Description

River and Marine Harvesters {Water sampler}

The present invention relates to a water harvester used for analyzing chemical components in river water and sea water, and more particularly, river and marine harvesters capable of accurate sampling at a desired depth by minimizing the resistance of water in rivers and oceans with strong water flow. It is about.

Generally, water collectors are used to sample water in rivers or oceans, and to investigate pollution, bacteria, and organisms according to depths.

Conventional water collectors are usually provided with a stopper at the inlet of the sump and connected to the string, when the water collector reaches a certain depth, by pulling the string to open the stopper was used.

However, this method has a disadvantage that accurate measurement is difficult because the water collector rises along the string connected to the stopper. Also, the weight of the weight alone is reduced to an arbitrary depth due to the influence of the air sealed by the material and the stopper. There was a problem that could not be reached correctly.

In addition, in the case of Nansen water collector, when the water collector is filled to a certain depth, some of the upper water remains in the water collector, and it is difficult to collect water accurately, and when the water collector is used in an area with strong water flow, the water collector is pushed into the water flow. There was a problem that the water depth of the water collector should be corrected because it is far from the intended area.

The present invention has been made to solve the above problems, an object of the present invention is less affected by the flow of water in the rivers or oceans where the flow of water is strong by a plurality of drains formed in the sump, and without additional correction work It is to provide a river and marine harvester that can be easily collected at the depth of water to be collected.

That is, the present invention is made of a cylindrical body of the upper and lower closure and the discharge port is provided on one side of the lower side, each of the four inlet and the upper and lower outer wall is provided with four fixing frames respectively on the upper and lower outer surface Water passage; A separator formed at an upper center portion of the basin and connected to a wire at a lower portion thereof and a drop guide at a lower portion thereof, and to connect or separate four tension lines in a lateral direction; A rubber stopper is provided to open and close the water collecting port, and a locking plate connected to a tension line at the center of the top and the bottom thereof, and a weight connected to the wire at the center of the water collecting container.

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

1 is a view showing the overall appearance of the water collector according to the present invention, and FIG. 2 is a cross-sectional view of FIG. 1, in particular the state where the water inlet 4 is opened by the engagement of the hooks 9a and 9b. Figure is shown.

1 to 2, the water collector of the present invention is a sump container 20, separator 30, locking plate 15, rubber stopper 2, tension line (8a, 8b) dropping weight (6), It consists of the wires 11a and 11b and the weight 10.

The sump container 20 is a cylindrical shape of the top and bottom is closed, made of a metal material that does not corrode in the sea water, the outer wall is a pair of top and bottom of the water collection port (4) has a space of 90 degrees in the circumferential direction, respectively Are arranged. In addition, a ring 13c is fixedly installed at the center of the lower surface of the sump 20, and four fixing frames 5a and 5b are fixed at equal intervals in the radial direction. Here, the fixing frame (5a, 5b) has a triangular shape, one side that is inclined to extend the long side is provided with a ring (13b) at its end.

In addition, an outlet 32 connected to the valve 33 is provided at one side of the lower side of the outer wall of the water container 20, and the weight 10 is vertically connected to the wire 11b to be fixed to the central portion ( Fixed to 13c).

On the other hand, the separator 30 is located in the center of the upper sump 20, the spring 24 and the guide piece 22 is built in the inside, the guide piece 22 has four lower hooks on its outer surface 9b is fixed and supported to linearly move up and down through the long grooves 28 formed at equal intervals on the outer surface of the separator 30. At this time, the lower hook 9b is temporarily engaged by the tension of the upper hook 9a and the tension line 8a connected thereto.

The locking plate 15 is provided with one rubber stopper 2 at the upper and lower portions of the inner wall thereof, and the upper and lower ends thereof are connected to the tension lines 8a and 8b to maintain a balance. When coupled to) is located at a distance from the outer wall of the sump (20). In this case, the rubber stopper 2 may be formed in various shapes as long as it can be easily opened and closed with the water inlet 4.

In addition, the tension lines (8a, 8b) connected to the locking plate 15 is connected to the upper hook (9a) through the ring (13b) on the fixing frame (5a) to the upper side, the ring (13d) to the lower side Is fixedly supported on, it is preferable that the lower one is provided to be a high tension than the upper.

Referring to the operation and action of the subject innovation constituted as described above are as follows.

First, when the locking plate 15 is pulled from the outer wall of the water container 20 so that the rubber stopper 2 is separated to open the water collecting port 4, the locking plate 15 is tension lines 8a and 8b. In spite of its elasticity, the upper hook 9a connected to the upper tension line 8a of the separated locking plate 15 is coupled to the upper hook 9a on the separator 30. In this case, the locking plate 15 is spaced apart from the sump 20 at a predetermined interval while being kept tight by the elasticity of the upper and lower tension lines 8a and 8b, and is relatively higher than the sump 4. It is located at. This operation is repeated in the same process for each locking plate (15).

On the other hand, if the fall weight (6) is not yet down to the separator (30), when operated in a state for collecting water as described above will be stored in the river or the sea to be collected water collector. Here, particular care should be taken so that the engagement of the upper hook 9a and the lower hook 9b is not released.

Once stored, the collected water collector is continuously lowered downward by its own weight and weight 10. That is, since a plurality of water collecting ports 4 of the water collecting container 20 are in an open state, there is no fear of receiving water pressure, so that the water can be freely stored to a desired depth.

At this time, the falling weight (6) is held by the worker on the water surface, the wire (11a) continues to release to the depth to be collected.

Once the water collector reaches the depth to be collected, the water container is in the water container 20 of the water collector, so the water collector 4 must be closed. Therefore, at this time, when the operator releases the dropping weight 6, the weight falls freely by its own load, and the dropping weight 6 is guided by the wire 11a to reach the water collector.

Figure 3 shows that the hook of the separator is separated by the impact of the dropping weight, showing that the rubber stopper of the locking plate closed the water collecting port.

Here, when the dropping weight 6 impacts the guide piece 22 of the separator 30 instantaneously, the guide piece 22 is lowered by the impact and the lower spring 24 is compressed.

At this time, the lower hook (9b) fixed to one side of the guide piece 22 is lowered at the same time as the guide piece 22 is lowered, the moment the engagement state with the upper hook (9a) is released. As the coupling state is released in this way, when the locking plate 15 is temporarily lowered by the preliminary elasticity of the tension lines 8a and 8b connected to the lower part of the locking plate 15, the rubber stopper 2 is formed there. The water collecting port 4 is closed while naturally moving to the water collecting hole 4 along the guide surface.

In addition, when the rubber stopper 2 is moved to close the water inlet 4, the instantaneous tension line 8a is caused by the contact between the inner wall of the locking plate 15 and the outer wall of the water container 20. The elasticity of 8b) prevents the rubber stopper 2 from being excessively fitted into the water inlet 4.

On the other hand, when the coupling of the hook (9a, 9b) is released and the locking plate 15 is lowered, the upper hook (9a) connected to the upper tension line (8a) is caught by the ring (13b) the locking plate ( 15) no longer deviates or falls.

When the water is completed by the above process, when the wire 11a is pulled or rolled up to the surface of the water, the water collector is pulled onto the water surface, and the water collecting operation is completed.

Of course, the collected water is to be discharged to the outside through the outlet 32 connected to the valve (33).

Particularly important in the above-mentioned harvesting process is the length and thickness of the lower tension lines 8a and 8b of the locking plate 15, which is connected to the tension of the tension lines 8a and 8b. If the lock plate 15 is too large, the locking plate 15 is lowered further downward than the water collecting port 4 so that the locking plate 4 cannot be completely blocked. On the contrary, when the tension is weak, the locking plate 15 temporarily stops due to water resistance. It is not possible to close the water collecting port 4 at the same time. Therefore, the design of tension lines 8a and 8b suitable for correct operation is of paramount importance.

According to the present invention having the above-described configuration, since the water flow can be minimized in a river or the sea where the water flow is strong by a plurality of water inlets formed in the water container, water of a depth to be collected It can achieve the effect that it can collect water accurately.
