Description

Dam fish transfer system using Shanghai-dong netting

The present invention relates to a fish movement system to prevent the destruction of the ecosystem by the smooth movement of the fish in the dam constructed in the river.

According to the present invention, when a dam is installed in a river, stream organisms such as fish are interrupted in the flow path between the upstream and the downstream of the dam, which causes a great problem in the ecosystem of the water and the inhabitants. Dams invade aquatic flora and fauna and invade the habitats of aquatic plants and animals. In addition, the installation of dams and beams will not only disrupt the movement paths of living creatures in the water, but will also disrupt the entire ecosystem based on rivers, making it difficult to move birds and terrestrial animals. .

According to Article 12, Paragraph 2 of the current Fishery Resources Protection Ordinance, "Anyone who wishes to install a workpiece that blocks the entire breadth of the river must consult with the Fisheries Commissioner to open a part of the river or to install a fishery to secure the passage of soha fish." Although the fish is being installed around the dam in accordance with this law, it has not had a good effect due to the lack of technology and many problems in construction.

Although many reservoirs and dams are installed all over the country, there are not many dams or reservoirs with fishes, and the research and recognition of fishes is very poor. Therefore, many environmental ecosystem problems have occurred.

The method of making a fishery is a walled fishery or a terraced fishery. The limit is usually applied to underwater beams where the gap between upstream and downstream is not so high. Such a method is usually used in the case of a stepped water surface in the field, but in this case also the case that the cement is easily damaged due to the winter, the effect is very insufficient. Another method is to make a prefabricated block in ice harbor type (stair type) and install it. These methods are not applicable when the water level difference between upstream and downstream of the Soyang River Dam or Multi-purpose Dam is severe.

The present invention has an object of the present invention to provide a method for automatic transport of fish using water level control to solve the above problems. The present invention attracts the fish so that the fish downstream or the fish upstream can move to where they want to move without any influence and creates a space for the manned fish to swim upstream and move upstream. It is to create a cycle that can move freely between upstream and downstream. Therefore, if the present invention is applied for the correct installation of the fish and secure the moving space of the fish, the ecosystem environment of the existing dam or the newly established dam will be improved, and the innovative invention that can prevent the extinction of fish species due to the free traffic of the fish to be.

The present invention is a device that is to build a system of the device on one side of the dam, unlike humans artificially capture the fish and move to the top and bottom. In addition, the device is a configuration of a system that can be used electrically or physically available.

As described above, the present invention uses the water level control between the upper end and the lower end of the dam, and due to the dam installed in the river, the movement of fish between upstream and downstream is not smooth, resulting in the destruction of the ecosystem. This device is a device that greatly contributes to the protection of the aquatic ecological environment by allowing fish to move upstream and downstream to spawn or move upstream and downstream due to seasonal changes.

The configuration and system of this device is a system that can be applied to any dam in the world by introducing the present system, which has not been able to make a fish passage because of the high water level difference between upstream and downstream while making a dam across the river. The added value for it is very large. In addition, it is an automatic transportation system of fish using the water level control that can install the fish irrespective of the high water level difference. It is a very innovative system that can be installed even if there is a vertical or inclined plane regardless of the altitude difference between the upstream and the downstream.

The configuration of the present invention is a fish manned passage and a structure having a door for opening and closing the fish can move between the upstream and downstream side, the net for moving the fish, the water pipe for adjusting the water level, the pulley and the light fixture as a forced transfer device and automatic control It consists of a system (Fig. 7).

In the structure with the fish movement and manned passage and opening and closing door, the moving passage (1) the upper manned passage (3) the lower manned passage (10) the hydraulic opening and closing door (4) the switchgear frame (14) to another opening and closing device (15) It is composed.

The net for moving the fish is composed of a conveying device net (5) floats (6) floats connection chain (7) mesh roller (19) connecting ring (26) connecting plate (27).

The water level adjusting water pipe is composed of limit switches 8 and 9 interlocked with opening and closing doors above and below the water level control water pipe 21 and the water level control valve 20.

The pulley and the light fixture, which is a forced transfer device, are configured of a motor 23, a reducer 24, a connection line 25, a pulley 29, a light 13, and a power supply 28 and a level sensor 30.

The automatic control system (Fig. 7) uses the lower limit switch (8) and the upper limit switch (9) and the water level control valve (20) and the light (13) and the motor (23) to control the opening and closing of the switchgear according to mutual purposes. It is a total control system that controls organically.

The above components are explained in parts as follows.

The moving passage 1 is a structure for utilizing the water level difference between the upstream and the downstream of the dam, and is a structure integrated with the fish attraction passage (3.10), and must be able to overcome a certain amount of water pressure in manufacturing. By using this passage, the fish moves up and down, and the fish moves up and down on the fish feeder net (5) integrated with the mouth.

Top and bottom manned passages (3.10) can be manufactured according to a certain size and surrounding landscape so that fish upstream can naturally gather. Then, a hydraulic pressure gate (4) is attached between the upper and lower manned passages (3.10) and the moving passage (1) to control the water level in the moving passage (1) to transfer the fish.

The role of the hydraulic opening and closing door (4) is installed at the upper and lower ends between the upper and lower manned passage (3.10) and the moving passage (1), and when the fish downstream moves upward, the hydraulic opening and closing door (4) at the upper part is closed. To prevent the water from moving downstream, and when the fish fills the transfer device net (5) at the lower end, close the water pressure opening and closing door (4) at the lower end, then open the water level control valve (20) to fill the water in the moving passage (1) After opening the upper hydraulic opening and closing door (4) is the main device to move the fish upwards.

The float lifting and seating part is composed of a motor (23) reducer (24) connecting line (25) connecting ring (26) pulley (29) applied power (28),

The conveying device net connected to the chain by a chain is composed of a conveying device net (5) floats (6) and chain linkage device (7) connecting ring (26) float connecting plate (27) mesh roller (19).

How to use is used as a means for moving the fish (2) by moving up and down in the passage (1). Closing the hydraulic opening and closing door (4) of the upper portion and the hydraulic opening and closing door (4) of the lower portion is opened, the fish enters the transfer device net (5) sagging on the bottom via the lower manned passage (10). To transfer the fish collected for a certain time, close the water pressure opening and closing door (4) at the lower part and open the water level control valve (20) to fill the water in the moving passage (1). The feeder net 5 will run up. At this time, the fish trapped in the conveying device net (5) is automatically transported to the water pressure opening and closing door (4) of the upper end at a rate that the water level rises. At this time, when the movement of the ball is not good, you can pull up or down using the pulley (29). And when you open the water pressure opening and closing door (4) of the upper end the fish will go out along the upstream water level (18). The feeder net (5) again stays at the upper end for a certain time to attract the fish, closes the hydraulic opening and closing door (4) at the upper end and drains the water by opening the hydraulic opening and closing door (4) at the lower end, and the mouth (6) falls down. The conveying device net (5) suspended on the float (6) also comes down to the floor. Then the fish comes down from the top to the bottom along the moving passage (1).

Hydraulic opening and closing door (4) of the upper and lower ends are installed between the moving passage (1) and the upper leading passage (3) and the lower leading passage (10), and the hydraulic opening and closing door (4) compression rubber (12) switchgear frame ( 14)). This is the main device for moving the fish and controlling the water level upstream and downstream for moving the fish. This apparatus is the present patent. Figure 2. 3 is illustrated. In addition to the method illustrated in the drawing (3), the water pressure opening and closing door may be changed to the device of the drawing (4), and the size and shape may be automatically adjusted by a local construction method.

The light 13 may be installed at a suitable position for attracting fish at the lower end or the upper end with a function of brightening the inside of the moving passage 1. In addition to the ability to attract fish can be used for emergency use in repairing the device.

The water level control device is composed of a water level control valve (20) and a water level control water pipe (21), a water level detection sensor (30), which floats a float (6) for transporting fish in the moving passage (1). It is used as a device for supplying water in the mobile passage (1) for lifting the fish upstream. When the lower pressure opening / closing door 4 is closed, the water level control valve 20 is opened to move the upstream water to the water pressure or automatic control system in conjunction with the sensor 30 until the same as the upstream water level 18. ) Serves to fill the water.

The automatic control system (Fig. 7) is composed of a timer and switchgear switch with a constant power supply for the operation of the present invention, and a limit switch (8.9) detecting sensor 30 at the end of the water pressure opening and closing door for safe operation. do.

Referring to the above components in detail the operation method by the accompanying drawings as follows. Upstream and downstream of the various dams blocking the river to create a moving passage (1) structure in which the fish can move freely so that the ecology of the fish can be completely restored. Referring to the system of the automatic fish feeder using the water level control of Figure 1 can be carried up and down the fish flow path (3.10) and fish on the upstream and downstream side, or the fish can move up and down on their own Make the tunnel for moving water level control (1). The mobile passage 1 can be constructed vertically or diagonally depending on the circumstances of the construction work and the state of the site. The hydraulic pressure difference between the upper part and the lower part may be long.

Make upstream and downstream fish passages (3.10) on the upstream and downstream sides of the level control passage, and at the end of the passage, create a hydraulic opening door (4) to overcome the water pressure. And fill the water so that the fish can move freely to the passage (1) of the fish to overcome the hydraulic pressure difference. At this time, the light 13 is placed on the upper or middle lower portion of the fish movement passage 1 using the water level control so that the fish can move smoothly so that the fish can move easily. Forced feeding device consisting of a mouth 6, a chain linking device 7 and a conveying device mesh 5 inside the fish passage 1 using the water level control as a forced device for the downstream fish to move upstream ( 5) By placing (Fig. 2) inside, it is possible to forcibly move the fish between the upper end and the lower end.

Buoy 6 has the same structure as the surface of the water at the bottom of the water level 18 and always floating on the surface, and the transfer device net (Fig. 2 (5)) has an opening and closing device on one side so that meat can easily enter and exit Meat coming into the passage is a structure that does not leave the fish passage (1) using water level control. This mouthpiece is a device for forcibly transporting fish from the lower water level 18 to the upstream dam surface, and is operated after staying for a time set by an automatic control system (FIG. 7) consisting of a timer and a switch for which a constant power is applied. Do it. For example, staying downstream for five hours forces the fish coming in through a fish mandatory to be forced upstream. At this time, the opening and closing device door (4) installed at the lower end of the hydraulic opening and closing door (4) installed at both ends by the moving passage (1) of the fish using the water level control to close and open the opening and closing device door (4) installed at the upper end. When the water is filled in the passage (1) of the fish using the water level control. Then, the float 6 rises upwards and the fish trapped in the transfer net mesh 5 connected to the float floats upwards as the water level rises in the fish passage 1 using the water level control. When the upper portion is moved to the upper portion of the upper net guide passage (3) to open the transfer net to move the fish to the water surface of the upstream side. In addition, after stopping the fish in the upstream side for a certain time, the water pressure opening and closing door (4) at the upper end of the fish passage (1) using the water level control is closed and the water pressure opening and closing door (4) installed at the lower end. When opened, the water in the flow passage of the fish using the water level control is gradually drained until the water level coincides with the water level at the lower side, and the transport net (5) connected with the chain on the upstream side 6 is moved downward. When it comes down to the downstream it is to open the transport net (5) to send the fish to the lower maneuvering passage 10 to go out downstream. Another way of using the mouthpiece 6 may be used only by adjusting the water level without using the apparatus of FIG. It is possible to allow the fish to move up and down by fixing the sub-spheres (5.6.7) to the lower end of the moving passage (1) so as not to float in water and to adjust the upper and lower water level (18). Most fish have a habit of going upstream rather than their position, so the fish entering the manned passage at the bottom move themselves upstream through the fish passage (1) using the water level control. Alternatively, the method of this patent allows the bottom vegetation fish to take advantage of the habit and use the stone to the inner conveyer mesh net 5 of FIG. can do.

The most important of this system is that the hydraulic doors (4) installed at both ends of the water flow between the upstream side and the downstream side always have the opposite action. When moving to the upstream side, lock the lower door, open the water level control valve 20 in the fish flow passage using the water level control, fill the water 22 through the water level control water pipe 21, and discharge the fish 2 upstream. Until the bottom hydraulic opening door (4) should be locked. On the contrary, in order to move the fish upstream to the downstream side, lock the bottom door and fill the water in the passage of the fish using water level control (1), lock the top door, open the bottom door, and slowly drain the water Ensure that the water level (18) is correct. The fish can then move freely from downstream to upstream and downstream. When the movement of the float (FIG. 5) is not smooth, it can be forcibly moved by using the float lifting device and the seating device (FIG. 6) installed above the moving passage.
