Description

Simultaneous collection of water sample and soft low quality sample

The present invention relates to a sampling device that can collect the sea water or the appeal of seawater by the depth, and also to collect the bottom layer water sample and soft low quality sample at the same time, more specifically, the approximate When moving to the upper part of the central part, it is possible to collect the water sample in the water layer and the water sample and the low quality sample at the same time by installing an opening and closing member to block the flow of water when moving to the lower side without blocking the flow of water. The present invention relates to an apparatus for simultaneously collecting water samples and soft low quality samples.

Generally, water and low quality samples are collected separately in seawater or in an appealing environment. Niskin or Van Dorn harvesters are used to collect water. Grab or box corerers are used to collect low quality samples. ), And according to the type of sample, that is, each sampling device is different for each water or low quality sample, it takes too much time for sampling. It is essential to work on the ship for the collection of marine and appeal samples, and the working time required for sampling takes longer in consideration of the worker's fatigue and work efficiency. As such, the conventional method needs to be improved.

In other words, in the case of the Niskin collector or Van Dorn collector, which is used to collect water samples for each water layer, open the lids attached to the upper and lower collectors, fix the collector body to a wire, lower the collector to the desired depth, and then add the weight on the ship. It is used to send a signal and to close the lid again to hold the desired water sample. However, such an operation may cause a case in which the sampling of the water is inadequate due to a mistake such as dropping a signal weight into the water when it is inexperienced, and the angle between the surface of the water and the wire to which the collector is attached due to the flow of underwater currents may occur. In case of narrowing, there were frequent failures such as the lid not closing correctly even if the weight was sent down.

In addition, in case of Grab collector or box type collector used to collect low quality samples, it is easy to be restricted by the ship used because the electric winch system must be attached to the ship due to the load of the collector itself. In the case of isotropic, the work load was inevitably larger than the required amount of sample.

The present invention is to solve such a conventional problem, in the case of collecting the sea water or the appeal water of the appeal by the depth of the water, especially the bottom-layer water sample and soft low-quality sample by a simpler structure to collect the water quickly and simultaneously It is an object of the present invention to provide an apparatus for simultaneously collecting samples and soft low quality samples.

As a technical configuration for achieving the above object, the present invention, the hollow-cylindrical cylindrical body is connected to each other to provide a flow path of the fluid in the vertical direction, and the upper portion of the stopper integrally fixed to protrude to the inner surface of the body It is provided by blocking the downward flow of the fluid, and the movement to the upper portion of the water sample and the soft low quality sample at the same time characterized in that the opening and closing member to be blocked by the support provided.

Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a cross-sectional view showing a water sample and a soft low quality sample at the same time according to the present invention, the upper and lower body of the upper and lower cylinders made of acrylic material, the upper and lower bodies 11, 12 are screwed together Is fastened to, the upper body 11 is a wire mesh screen member 21 is installed in the open portion of the upper end, the lower body 12 is a wire mesh screen member 22 is installed in the open portion of the lower end do.

The rod-shaped support 30 is fixed in the radial direction inside the upper end of the lower body 12, and forms a hole 32 penetrating up and down in the center portion of the support 30, the slide 32 in the slide 42 is fitted to slide in the vertical direction, the lower end of the slide 42 is fixed integrally to the upper end of the center of the opening and closing member (50).

The opening and closing member 50 is made of a material whose specific gravity is slightly larger than the specific gravity of water, for example, seawater or lake water, for sample collection, which protrudes on the inner surface of the lower body 12 and is fixed to the stopper 52. By being configured in a shape that is placed on the) the distance between the stopper 52 and the support 30 is limited.

In addition, a discharge pipe 60 for discharging the sample water is installed on the upper side of the support 30 of the lower body 12, and the discharge pipe 60 is provided with an opening / closing valve 62.

In addition, the lower end portion of the lower body 12 forms a wedge-shaped protrusion 70 so as to easily dig the soft poor surface, through which the soft poor sample such as nizil or 뻘 at the moment the collecting device is stuck to the bottom of the low quality. To be drawn into the body (12).

In addition, the lower portion of the lower body 12 is fixed to the lower portion of the weight 80 made of lead, etc. having an appropriate weight, the weight 80 is lowered for the device to collect the sample more quickly Assist you in doing so.

The device having such a configuration is used to simultaneously collect water and low quality samples in seawater or an appealing environment. When descending to seawater or lake water for sampling, the device can descend at an appropriate speed by the weight 80. At this time, the flow of the fluid passing through the lower screen member 22 and the upper screen member 21 is formed, the opening and closing member 50 is raised to the support 30 by the pressure of the fluid flow to the flow of the fluid It will descend without being blocked.

When the bottom side is reached after the continuous descent, the lower portion of the protrusion part 70 digs into the soft poor surface and is erected vertically, and at the same time, the soft poor sample such as nizil or sap enters the upper part of the opening and closing member 50, The opening and closing member 50 is gradually lowered due to the specific gravity difference and is placed on the stopper 52. Therefore, when the device is raised after an appropriate time, a soft poor sample is placed on the upper side of the opening and closing member 50, and its softness is increased. On the upper side of the low quality sample, water samples of the bottom can be collected.

Of course, in order to collect the water sample at any point other than the bottom, when the device is raised again to the point in the lowered state, ascending opening and closing member 50 is lowered as described above to confine the water sample inside the body. As the water sample can be collected.

That is, when the device is lowered, the opening and closing member 50 rises and water may pass through the inside of the body, and when the sample is temporarily stopped at the desired depth and rises again, the opening member 50 automatically stops ( 52), it is a principle to trap the water sample inside the body.

At this time, the water sample can be collected through the discharge pipe 60, the low quality sample can be collected by separating the upper and lower body (11, 12) from each other.

In more detail, the device is attached perpendicularly to the collecting line, and the grid size of the screen member 22 is about 5 mesh to facilitate the introduction of soft poor materials. In addition, the weight 70 is set to about 10kg so that the vertical drop can be made smoothly by increasing the falling speed in the water layer. In addition, the lower end portion is formed with a wedge-shaped protrusion 70 for the low seam-separated depth of 10 cm in order to be deeply embedded in the soft poor surface layer.

In addition, the opening and closing member 50 mounted on the stopper 52 is formed to flow toward the support 30 when the apparatus is lowered so that water flows through the inside of the body, whereas when it is raised again, By moving to the stopper 52 side to block the flow flowing through the inside of the body to prevent the water sample outflow to the outside of the body.

As described above, according to the simultaneous collection device for water sample and soft low quality sample according to the present invention, when the device descends to the center of the approximately hollow park barrel body, the device moves to the upper side and ascends without blocking the flow of water. By moving to the lower side to block the flow of water can be used to collect the water sample in the water layer and the water sample and the low quality sample at the bottom layer at the same time.

Therefore, it is possible to collect the water sample of the desired depth by simple manual operation when collecting the water sample in the sea water or the appeal environment, and in the case of a soft low-quality environment, it is excellent in practical use to collect and separate the water sample and the sediment sample at the bottom layer at the same time. Has an effect.
