DETAILED DESCRIPTION OF THE EMBODIMENTS
[40] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only part of the embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without inventive effort fall within the scope of the present invention.
[41] In order to make the above-mentioned object, features, and advantages of the present invention more obvious and easier to understand, the present invention is described in further detail below in conjunction with the accompanying drawings and specific implementations.
[42] As shown in FIGS. 1-14, the present invention discloses an apparatus for harvesting algae 13, including a harvesting ship 1 configured to harvest algae 13 cultivated in a flat culture pattern of multi-strand rope 14, and at least one storage compartment 2 configured to store harvested algae 13. At least one set of traction assemblies are provided on the harvesting ship 1, and the traction assemblies may drag a seedling rope 12 with algae 13 attached in water to the front of the harvesting ship 1 and then drag the seedling rope 12 into the storage compartment 2, and these two functions are achieved by a first traction assembly and a second traction assembly of the traction assemblies. The top of the storage compartment 2 has an opening for the seedling rope 12 to enter. The traction assemblies include the first traction assembly configured to drag strand ropes 14 in water to the harvesting ship 1 and the second traction assembly configured to drag the seedling rope 12 into the storage compartment 2. The first traction assembly includes two first transmission mechanisms 6 which are provided on two sides of the top of the opening and configured to be connected to the strand ropes 14, and a first driving mechanism configured to drive the first transmission mechanisms 6 to rotate to drag the strand ropes 14 to the harvesting ship 1. The second traction assembly includes two second transmission mechanisms 7 which are provided on two sides of the top of the opening and configured to be connected to the seedling rope 12, and a second driving mechanism configured to drive the second transmission mechanisms 7 to rotate to drag the seedling rope 12 into the opening. The first transmission mechanism 6 is located outside the second transmission mechanism 7.
[43] When the harvesting ship 1 moves to a flat cultivation region of multi-strand rope 14, after the first transmission mechanisms 6 on the harvesting ship 1 are correspondingly aligned with the strand ropes 14 in any ridge, the strand ropes 14 are connected to the first transmission mechanisms 6 manually or robotically, and then the first driving mechanism is started. The first driving mechanism drives the first transmission mechanisms 6 to rotate to drag the strand ropes 14 in water out of the water surface and to the front of the harvesting ship 1. After the strand rope 14 is dragged to the front of the harvesting ship 1, the seedling rope 12 is released from the strand rope 14 manually or robotically, and the seedling rope 12 is connected to the second transmission mechanisms 7. At this time, the second driving mechanism is started to drive the second transmission mechanisms 7 to rotate so that the seedling rope 12 and the algae 13 attached to the seedling rope 12 are dragged into the opening of the storage compartment 2, thereby completing the harvesting of the algae 13 on a single seedling rope 12.
[44] In the present invention, the strand ropes 14 in the water are dragged to the harvesting ship 1 through the first traction assembly, and the seedling rope 12 is dragged into the storage compartment 2 through the second traction assembly, achieving automatic harvesting of algae 13.
Compared with the method of manually dragging the strand ropes 14 in the related art, the present application reduces the manpower required for harvesting the algae 13 and improves the efficiency of harvesting the algae 13.
Meanwhile, compared with directly placing the harvested algae 13 on a deck of the harvesting ship 1, the present invention places the harvested algae 13 into the storage compartment 2, which isolates the harvested algae 13 from an external environment and avoids direct exposure to natural factors such as sunlight, wind, and sea birds, thereby reducing the risks of drying, spoilage, or damage to the algae 13. Additionally, it prevents the algae 13 from sliding and scattering on the deck and also minimizes contact between the algae 13 and oils, detergents, or other substances on the deck that may impact the quality of the kelp.
[45] The apparatus for harvesting algae 13 in the present invention may be configured to harvest algae 13 in the flat culture pattern of multi-strand rope 14 such as a two-strand rope 14, a three-strand rope 14, a four-strand rope 14, and a five-strand rope 14. The harvesting ship 1 in the present application may be a multi-hull ship such as a catamaran, a trimaran, a dquadrimaran, and a pentamaran. The specific type of the flat culture pattern of multi-strand rope 14 for harvesting depends on the type of the harvesting ship 1. For example, when the harvesting ship 1 is the catamaran, the apparatus for harvesting algae 13 in the present invention may be configured to harvest algae 13 in the flat culture pattern of two-strand rope 14, and one set of traction assemblies are provided one the catamaran. When the harvesting ship 1 is the trimaran, the apparatus for harvesting algae 13 in the present invention may be configured to harvest algae 13 in the flat culture pattern of three-strand rope 14, and one and a half sets of traction assemblies are provided on the trimaran, i.e., a set of traction assemblies + one first transmission mechanism 6 + one first driving mechanism + one second transmission mechanism 7 + one second driving mechanism. When the harvesting ship 1 is the pentamaran, the apparatus for harvesting algae 13 in the present invention may be configured to harvest algae 13 in the flat culture pattern of five-strand rope 14, and two and a half sets of traction assemblies are provided on the pentamaran, i.e., two sets of traction assemblies + one first transmission mechanism 6 + one first driving mechanism + one second transmission mechanism 7 + one second driving mechanism. The present invention may be configured to harvest kelp, undaria pinnatifida, porphyra, or other mature algae 13 that may be cultivated in the flat culture pattern of multi-strand rope 14.
[46] As shown in FIGS. 10-12, two ends of the strand rope 14 are connected to anchor piles 16 fixed in a seabed 15 through anchor ropes 18 to fix the strand rope 14. A plurality of floating balls 17 are provided on the strand rope 14 to ensure that the strand rope 14 may be located in a water area of a corresponding depth.
[47] Further, in the present invention, the first transmission mechanism 6 includes at least one clamping wheel set provided along a travel direction of the harvesting ship 1. The clamping wheel set includes two oppositely arranged clamping wheels, and a rotation axis of the clamping wheels is perpendicular to the travel direction of the harvesting ship 1. A gap between the two clamping wheels is not greater than a diameter of the strand rope 14 so that the strand rope 14 does not jump out of the clamping wheel set when driven by the clamping wheel set. The first transmission mechanism 6 is fixed to the harvesting ship 1 through a support frame 15.
[48] When the above-mentioned first transmission mechanism
G is used, since the gap between the two clamping wheels is not greater than the diameter of the strand rope 14, the strand rope 14 will not jump out of the clamping wheel set during the process of being dragged, ensuring the continuity of the dragging of the strand rope 14 and the harvesting of the algae 13. Meanwhile, compared with the traditional way of pulling the strand rope 14, since the two clamping wheels form a clamp on the strand rope 14, the pulling force is not concentrated in a small region, but is evenly distributed over the whole region where the strand rope 14 contacts the clamping wheels. Therefore, the pulling force that the strand rope 14 receives between the two clamping wheels will be more dispersed and uniform, thus reducing the risk of damage to the strand rope 14 or kelp due to the concentrated pulling force, thereby protecting the integrity of the strand rope 14 and the algae 13. Thus, the strand rope 14 may continue to be used for suspending the seedling rope 12 so that the algae 13 may be harvested with a high harvesting quality. Meanwhile, the clamping wheel set in the present invention reduces the contact of the strand rope 14 with other parts of the harvesting ship 1, reducing equipment wear and maintenance costs. In addition, in the present invention, a spacing between the two clamping wheels may be adjusted according to different diameters of the strand rope 14 so that the gap between the two clamping wheels is not larger than the diameter of the strand rope 14.
[49] Alternatively, the first transmission mechanism 6 in the present invention may not adopt the above-mentioned structure. Specifically, the first transmission mechanism 6 in the present invention includes a winch, a cylinder, or a roller provided along the travel direction of the harvesting ship 1 and having a rotation axis perpendicular to the travel direction of the harvesting ship 1. The winch, cylinder, or roller is configured to wind the strand rope 14. When the winch, cylinder, or roller is used as the first transmission mechanism 6 in the present invention, a rope wound on the winch, cylinder, or roller may be connected to the strand rope 14 to wind the strand rope 14 through the winch, cylinder, or roller. Alternatively, a rope may not be wound on the winch, cylinder, or roller, and one end of the strand rope 14 may be wound directly on a periphery of the winch, cylinder, or roller. After the winch, cylinder, or roller winds the strand rope 14, the first driving mechanism is started to drive the winch, cylinder, or roller to rotate so that the strand rope 14 is gradually wound and dragged to the harvesting ship 1, and since the seedling rope 12 hangs on the strand rope 14, which means that while the strand rope 14 is dragged to the harvesting ship 1, the seedling rope 12 is also dragged to the harvesting ship 1.
[50] The second transmission mechanism 7 in the present invention has various structures. For example, the second transmission mechanism 7 in the present invention includes a transmission chain provided along the travel direction of the harvesting ship 1, and a rotation axis of the transmission chain is perpendicular to the travel direction of the harvesting ship 1. At least one connecting piece 11 configured to cooperate with the seedling rope 12 is provided on the top or a side of the transmission chain, and the connecting piece 11 releases a connection relationship with the seedling rope 12 when the seedling rope 12 is dragged over the opening so that the seedling rope 12 and the algae 13 fall into the storage compartment 2. The cooperation between the connecting piece 11 and the seedling rope 12 meant that the seedling rope 12 may be bound to the connecting piece 11 or sheathed on the connecting piece 11.
Which method is chosen depends on the type of the connecting piece 11 and the type of the seedling rope 12. The provision of the connecting piece 11 avoids direct contact of the transmission chain with the seedling rope 12 and the algae 13, ensuring the integrity of the seedling rope 12 and the algae 13. There is a gap between the transmission chain and the deck of the harvesting ship 1 so that when the transmission chain rotates, there is no interference between the deck and the connecting piece 11. In addition, the situation that a small gap between the transmission chain and the deck of the harvesting ship 1 allows the deck of the harvesting ship 1 to abut against the connecting piece 11, resulting in an interruption of the rotation of the transmission chain will be avoided, ensuring the continuity of the operation of dragging the seedling rope 12 into the storage compartment 2, and improving the efficiency of harvesting the algae 13.
[51] Further, the second transmission mechanism 7 in the present invention may not adopt the above-mentioned structure. At this time, the second transmission mechanism 7 includes a winch or a pulley block provided along the travel direction of the harvesting ship 1 and having a rotation axis perpendicular to the travel direction of the harvesting ship 1. A rope is wound on the winch or the pulley block, at least one connecting piece 11 configured to cooperate with the seedling rope 12 is provided on the top or a side of the rope, and the connecting piece 11 releases a connection relationship with the seedling rope 12 when the seedling rope 12 is dragged over the opening so that the seedling rope 12 and the algae 13 fall into the storage compartment 2. In this structure, the second transmission mechanism 7 differs from the second transmission mechanism 7 of another form mentioned above only in that: in this structure, the transmission chain is replaced with the winch or the pulley block wound with a rope.
[52] When the travel speed of the harvesting ship 1 is relatively slow or a spacing between adjacent seedling ropes 12 is relatively large, only one connecting piece 11 may be provided on the second transmission mechanism 7. At this time, a construction cost of the apparatus for harvesting algae 13 is low, but the corresponding harvesting efficiency is low. A plurality of connecting pieces 11 may also be provided on the transmission chain to obtain a high harvesting efficiency.
[53] In the present invention, the connecting piece 11 has various forms and may be a clamping mechanism capable of clamping/loosening the seedling rope 12, a snap mechanism/magnetic attraction mechanism capable of locking two ends of the seedling rope 12 on the second transmission mechanism 7/loosening the seedling rope 12, a knot releasing mechanism capable of fixing two ends of the seedling rope 12 on the second transmission mechanism 7/loosening the seedling rope 12, or a hook cooperating with the seedling rope 12. The specific type of the connecting piece 11 is determined depend on factors such as the type of algae 13 being harvested, the harvesting efficiency, the harvesting quality, and the cost budget.
[54] Further, in the present invention, a strut is provided between the connecting piece 11 and the second transmission mechanism 7 and is provided on a side of the second transmission mechanism 7 facing the other second transmission mechanism 7. At this time, the connecting piece 11 is located between the two second transmission mechanisms 7, reducing an occupation area of the second traction assembly in a vertical direction.
[55] When the connecting piece 11 in the present invention is a hook, the hook may be in the shape of a straight bar or has a bent portion at a terminal end, such as a J-hook or an S-hook. At this time, the seedling rope 12 is directly sheathed on the hook, so when the second transmission mechanism 7 rotates counterclockwise until the rearmost end of the second transmission mechanism 7 begins to enter a next turn, the seedling rope 12 will fall off from the hook and enter the storage compartment 2, thereby achieving automatic separation of the seedling rope 12 from the connecting piece 11 and improving the efficiency of harvesting the algae 13.
[56] Further, in the present invention, the storage compartment 2 is a transport ship configured to transport the harvested algae 13, or a storage box provided on the harvesting ship 1. A net bag 3 configured to contain the harvested algae 13 is provided in the storage compartment 2, and the net bag 3 may also be replaced with a fishing net. When the storage compartment 2 is the storage box provided on the harvesting ship 1, the storage box is slidably connected to the harvesting ship 1, and a driving apparatus configured to drive the storage box to slide is provided on the harvesting ship 1 so that the harvested algae 13 sequentially enter until the storage box is filled.
As shown in FIG. 5, a slideway 4 slidably cooperating with the storage box is provided on the harvesting ship 1. The harvesting ship 1 is the multi-hull ship. The front of the harvesting ship 1 is provided with a plurality of rows of unpowered rotating cylinders 8 configured to reduce damage to the algae 13 when boarding.
[57] The front of the harvesting ship 1 is further provided with a rope untying assembly configured to untie a connecting rope 9 to untie the seedling rope 12 from the strand rope 14, and a specific structure of the rope untying assembly may refer to a U-shaped uncoiling piece in the patent document CN109699284B, an uncoiling device in the patent document CN107580865B, or a rope untying device in the patent document CN104756667B. An unhooking apparatus configured to remove the seedling rope 12 from the second transmission mechanism 7 is provided on the harvesting ship 1, and a specific structure of the unhooking apparatus may refer to an automatic unhooking limiting apparatus in the patent document CN106258191A. The apparatus for harvesting algae 13 further includes a transfer mechanism 19 configured to transfer the harvested algae 13 to a transfer ship 10 after the storage compartment 2 is filled with the harvested algae 13. The transfer mechanism 19 is provided on the transfer ship 10.
[58] In the present invention, the first driving mechanism and the second driving mechanism are rotary driving mechanisms which may drive the first transmission mechanisms
6 or the second transmission mechanisms 7 to rotate, such as a rotating motor and a motor. The transfer ship 10 is provided with a fuel tank 20, a hydraulic oil tank 21, and a seawater valve box 22.
[59] The present invention also provides a method for harvesting algae 13 applying the above-mentioned apparatus for harvesting algae 13, including the following steps. At
S1, the harvesting ship 1 and the transfer ship 10 cooperating with the harvesting ship 1 are moved to one ridge in a flat culture kelp cultivation area of multi- strand rope 14, and the harvesting ship 1 is moved to one end of strand ropes 14 in the ridge. The two first transmission mechanisms 6 are aligned with two strand ropes 14, respectively, and the first transmission mechanisms © are connected to the corresponding strand ropes 14.
[60] At S2, the first driving mechanism is started to drive the first transmission mechanisms 6 to rotate to drag submerged strand ropes 14 to the harvesting ship 1.
Meanwhile, the harvesting ship 1 is gradually moved from one end of the strand ropes 14 to the other end of the strand ropes 14. A travel speed of the harvesting ship 1 matches a speed at which the strand rope 14 is dragged.
[61] At $3, after the strand rope 14 is dragged to the harvesting ship 1, the second transmission mechanism 7 is connected to the seedling rope 12, and the second driving mechanism is started to drag the seedling rope 12 to the storage compartment 2. When the seedling rope 12 moves above the opening, a connection relationship between the second transmission mechanism 7 and the seedling rope 12 is released, and the seedling rope 12 and the algae 13 attached to the seedling rope 12 fall into the storage compartment 2, thereby completing the harvesting of the algae 13 on one seedling rope 12.
[62] At S4, 52-53 are repeated until all of the seedling ropes 12 and the algae 13 on two strand ropes 14 in the ridge are harvested into the storage compartment 2. S1-54 are repeated after all algae 13 in the ridge are harvested.
[63] After one end of the storage compartment 2 is filled with the harvested algae 13, the storage compartment 2 is moved to fill the other end of the storage compartment 2 with the harvested algae 13.
