JPH0656080A - Device for mounting and removing mooring rope and mooring chain provided in flat - Google Patents

Abstract

PURPOSE:To easily perform construction of set up, withdrawal, transfer, etc., of a device by forming a screw bar into a pipe shape in the device for adjusting length, and inserting a wire or a rope into the pipe, in the screw bar, so as to perform work by a simple means. CONSTITUTION:An upper end of a mooring chain 7 is placed to approach an eye metal fixture 11 by using a wire 12, by operating a winch 13, to connect both the chain and the fixture by a connecting metal fixture 14 or the like. Next, the wire 12 is set free from the mooring chain 7 and stored in the winch 13. Then a handle 10 is turned to lift a screw bar 9 in an upward direction, and the mooring chain 7 is placed in a tense condition and hoisted to a position where a piston 4 can be vertically moved in a cylinder. Thus, swiveling of a float 1 is transmitted to the piston 4.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a float floating on the ocean and its mooring.

[0002]

2. Description of the Related Art With regard to floats such as wave power pumps currently in use, there is no countermeasure for attaching and detaching mooring lines and mooring chains of the float, so that a very large crane carrier or the like is required. I had no choice but to work with it.

[0003]

[Problems to be Solved by the Invention] Regarding the mass diffusion of wave power pumps and the like, which are expected to be active in the future under the above-mentioned circumstances, there are major problems in design, manufacturing and installation cost reduction, and safety during work. It was

[0004]

[Means for Solving the Problems] The present invention addresses the above-mentioned problems by providing an adjusting device or a jack handle for adjusting the lengths of mooring lines and mooring chains at approximately the center of the float. In addition, using a pipe or the like for the threaded screw rod that also serves as the main trunk of this device, pass an auxiliary wire or the like through this pipe, connect one end of the wire to a mooring line or mooring chain, etc., and place the other end on the float. Tie to a simple winch. That is, by operating the winch, the wire is wound up, and the mooring line and the mooring chain are drawn to the connection portion at the substantially central portion of the target float.

Next, the mooring rope and the mooring chain thus attracted are connected to the float connecting portion by using a shackle or a connecting hardware.

[0006]

With this device constructed by using the above-mentioned means, a wire penetrating the inside of the threaded rod provided in the substantially central portion of the float is wound up by a winch or the like provided on the float, and both Bring closer. Therefore, with this method, a mooring line or a mooring chain can be connected to the float by a relatively simple means.

Embodiments Embodiments in which the present invention is applied to a wave pump will be described below with reference to the drawings. FIG. 1 is a vertical cross-sectional view showing the configuration of the device of the present invention. The configuration and operation of this figure will be described below.

First, a float 1 which oscillates due to waves is placed on the surface of the sea, and a saddle 2 and a cylinder 3 of a wave pump are installed on the bottom of the sea as shown in the figure. A piston 4 is provided in the cylinder, and a piston rod 5 is provided at the center thereof. An eye plate 6 is provided on the upper end of the piston rod, and a mooring chain 7 is connected to the eye plate 6. On the other hand, a threaded rod 9 made by processing a pipe or the like is passed through the inside of a main column pipe 8 provided at a substantially central portion of the float 1 floating above the sea surface. A handle 10 is provided on the upper end of the screw rod, and the screw rod can be moved up and down by rotating the handle.

An eye fitting 11 is attached to the lower end of the screw rod.
Is also provided. Next, a wire 12 is passed through the pipe of the threaded rod, and one end of this wire is tied to the mooring chain 7 described above. The other end corresponding to this is tied to the winch 13 provided on the float, and the wire can be wound by operating the winch. Next, this operation and operation will be described below.

In the construction of this device described above, if the upper end of the mooring chain 7 is wound with the wire 12 by operating the winch 13 provided on the float, the upper end of the mooring chain 7 is , The eye fitting 11 provided at the lower end of the screw rod 9 can be approached. That is, when the two are in close proximity to each other, the both are connected by using a shackle or a connecting fitting 14.

Next, the above-mentioned wire 12 is released from the mooring chain 7 and stored in the winch 13 provided on the float. With the above operation, the float 1 on the sea surface and the piston 4 provided on the sea bottom are connected via the mooring chain 7, but the mooring chain 7 is not in a tension state at this stage.

As the next operation, the handle 10 provided on the float is turned to lift the screw rod 9 upward. That is, if the mooring chain 7 is in a tensioned state and the piston is lifted up to a position where it can move up and down in the cylinder, the swing of the float 1 is transmitted to the piston 4. In other words, it can be said that the wave pump is in operation.

The above operation is a procedure for connecting the mooring rope and the mooring chain to the float, and when releasing them from the float, the operation reverse to the above-mentioned procedure may be performed. Therefore, the description of this operation will not be repeated.

EFFECTS OF THE INVENTION The present invention has the effects as described below in the field of wave power pumps and the like because the apparatus is configured as described above. 1. When the equipment became large, it became possible that installation work on the ocean was not possible. 2. Installation costs have become very cheap. 3. During the installation work period, it became possible to work safely in terms of labor. 4. As a result of easy installation, removal, and relocation of the equipment, maintenance of the equipment can be done on the dock and on land. 5. If the maintenance and repainting of the device can be performed relatively easily, the life of the device is extended. When the life of the device is extended, cost calculation such as power generation cost of electric power cost in the electric power industry becomes very cheap, and it is possible to do something that is not profitable.

In general, the wave power pump is used to replace the water in the harbor, to be used as a water supply pump for anti-icing, to cancel the wave in the sea area during the construction of a port, and to protect the global environment from the viewpoint of ocean environment. Although there are various uses such as purifying water, the scale of the device becomes enormous regardless of which one is used. However, the effects of the present invention can be made impossible, and will greatly contribute to global environment conservation and future energy development, energy saving, marine development industry and the like.
