Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to an ecological water conservancy project device adapted to the connection between rivers and lakes. Background Technique

[0002] A water conservancy project is a complex of different types of hydraulic structures built at suitable sections of a river or a channel to meet the goals of various water conservancy projects for harnessing rivers and eliminating disasters. Since the water conservancy project cuts off the water flow, the fish in this ecological environment are blocked by the water conservancy project, resulting in the inability of the fish school to migrate, and further leading to changes in the local ecological environment. In order to avoid this phenomenon, an ecological water conservancy project device adapted to the connection between rivers and lakes is needed.

[0003] In the prior art, in order to reduce the impact on the migration of fish schools, most water conservancy projects usually build a water trough with a small slope. In order to reduce the water flow velocity in the water trough, a large number of obstacles with special shapes are also required to be built in the water trough. This method not only has a high construction cost, but also cannot provide much help for the migration of fish schools during actual use. Content of the Utility Model

Detailed Embodiments

[0030] The following is further described in conjunction with the embodiments shown in the accompanying drawings.

[0031] For convenience of description, in this embodiment, Figure 2 the left side is the front and the right side is the rear, where Figure 2 the left side is the downstream direction of the dam body 1, and the right side is the upstream direction of the dam body 1.

[0032] As Figures 1 to 3 shown, the ecological water conservancy hub device adapted to the connection between rivers and lakes includes a dam body 1, a lifting groove assembly, a lifting assembly, and a guiding groove 3. A plurality of overflow grooves 2 are formed on the dam body 1 so that fish upstream of the dam body 1 can swim to the downstream of the dam body 1 through the overflow grooves 2. The lifting groove assembly is arranged on the downstream side of the dam body 1 and includes a second lifting groove 8 and a plurality of first lifting grooves 7. The second lifting groove 7 is arranged at the bottom; each first lifting groove 7 is arranged at equal intervals above the second lifting groove 8 and is arranged in a stepped manner, and the first lifting groove and each second lifting groove are fixed on the dam body by a lifting assembly. The lifting assembly is arranged on the dam body 1 and drives the lifting groove assembly to move vertically so as to convey the fish group from the lifting groove assembly to the guiding groove 3.

[0033] As Figure 5 shown, the lifting assembly includes a sleeve 5, a piston 21, a sleeve rod 6, a drain pipe 20, a first solenoid valve 19, a water inlet pipe 11, and a second solenoid valve 22. The sleeve 5 is fixed on the dam body 1 and is hollow inside; the piston 21 is vertically slidably positioned in the sleeve 5; one end of the sleeve rod 6 is fixedly connected to the piston 21 and the other end vertically passes through the top of the sleeve 5. The drain pipe 20 is installed in the sleeve rod, one end of the drain pipe 20 penetrates the piston 21, and the other end extends out of the side wall of the sleeve rod 6; the first solenoid valve 19 controls the on-off of the drain pipe 20 so as to drain the water in the sleeve 5. The water inlet pipe 11 passes through the bottom of the sleeve 5 and can inject water into the inside of the sleeve 5; the second solenoid valve 22 is used to control the on-off of the water inlet pipe 11. In this embodiment, a communicating pipe 32 is laid inside the dam body 1; one end of the communicating pipe 32 extends to the upstream of the dam body 1, and the other end communicates with the water inlet pipes 11 of each lifting assembly; a cover body 9 is arranged at one end of the communicating pipe 32 located upstream of the dam body, and a first filter screen 10 is arranged on the inner side wall of the cover body to prevent impurities in the water upstream of the dam body 1 from entering the communicating pipe and ensure the normal operation of the lifting assembly.

[0034] During operation, the water upstream of the dam body 1 enters the sleeve 5 of the lifting assembly through the communicating pipe 32. Under the action of water pressure and in cooperation with the piston 21, the sleeve rod 6 rises. When the sleeve rod 6 rises, the corresponding first lifting groove 7 or second lifting groove 8 is driven to rise.

[0035] As Figure 4As shown, the first lifting groove 7 includes a first groove body 7-1, two first sliding grooves 12, first sliding blocks 13, first baffles 14 and first partition plates 15. The front and rear sides of the first groove body 7-1 are respectively provided with notch openings. Two first sliding grooves 12 are vertically opened at the front notch opening of the first groove body 7-1; the first sliding blocks 13 are in sliding fit with the first sliding grooves 12; the first baffles 14 are fixedly connected to the first sliding blocks 13; the first partition plates 15 are fixed to the bottom of the first groove body 7-1. Two adjacent first lifting grooves 7 are arranged vertically, and the notch opening at the rear side of the lower first lifting groove 7 is in contact connection with the first partition plate of the upper first lifting groove 7.

[0036] As Figure 6 , Figure 7 shown, the second lifting groove 8 includes a second groove body 8-1, a sealing plate 26, connecting rods 29, a connecting plate 28 and springs 30; in this embodiment, there are four connecting rods 29, connecting plates 28 and springs 30 respectively. The rear side of the second groove body 8-1 is provided with a notch opening, and a plurality of water leakage holes 25 are evenly arranged on the bottom surface; a second filter screen 24 is arranged on the side surface of the second groove body 8-1. The sealing plate 26 is vertically movably installed below the second groove body 8-1; a through hole 27 for the lifting assembly to pass through is opened on the sealing plate 26 so that the lifting assembly is connected to the bottom of the second groove body 8-1. The connecting rods 29 are fixed to the bottom surface of the second groove body 8-1 and pass through the sealing plate 26 and are fixedly connected to the second groove body 8-1. The connecting plate 28 is fixed to the bottom of the connecting rod 29; the springs 30 are fixed between the sealing plate 26 and the connecting plate 28. The notch opening at the rear side of the second lifting groove 8 is in contact connection with the first partition plate 15 of the adjacent first lifting groove 7. A fish bait storage box 23 is arranged in the second groove body 8-1. The fish bait storage box 23 is of a porous structure and is used to attract fish groups to gather in the second lifting groove 8.

[0037] The working mode of the lifting groove assembly for lifting fish groups step by step is as follows:

[0038] During the upward movement of the second lifting tank 8, when the second lifting tank 8 contacts the nearby first baffle 14, with the upward movement of the second lifting tank 8 and the sliding between the first slider 13 and the first chute 12, the first baffle 14 is lifted. At this time, the water and fish in the second lifting tank 7 flow into the first lifting tank 7. Then, the second electromagnetic valve 22 corresponding to the first lifting tank 7 is turned on, and the first lifting tank is lifted through the corresponding sleeve 5, piston 21, and sleeve rod 6. During the upward movement of the first lifting tank 7, under the action of gravity, the first baffle 14 gradually resets to seal the front slot opening of the first lifting tank 7, and the rear slot opening of the first lifting tank 7 is also in a sealed state under the action of the adjacent first partition 15. Thus, the fish and water are further lifted through the first lifting tank 7. At the same time, during the upward movement of the second lifting tank 8, the water passing through the water leakage hole 25 presses the sealing plate 26, causing the sealing plate 26 to slide downward along the connecting rod 29, and then leaking out of the water leakage hole 25, so that the water above the second lifting tank 8 can flow out through the water leakage hole 25 and the gap between the second lifting tank 8 and the sealing plate 26, further reducing the water flow degree above the second lifting tank 8 and avoiding disturbing the fish.

[0039] The guiding groove 3 is fixed on the top of the dam body 1 and is used to connect the upstream and downstream of the dam body 1. As Figure 8 shown, the guiding groove 3 includes a guiding groove body 3-1, a support column 4, a second chute 31, a second slider 17, a second baffle 16, and a second partition 18. The front and rear sides of the guiding groove body 3-1 are respectively provided with slot openings; the support column 4 is fixed on the dam body 1 and is used to support the guiding groove body 3-1. Two second chutes 31 are vertically provided at the front slot opening of the guiding groove body 3-1. The second slider 17 is slidably matched with the second chute 31; the second baffle 16 is fixedly connected with the second slider 17. The second partition 18 is fixed at the bottom of the guiding groove body 3-1, and the second partition 18 of the guiding groove 3 is in contact connection with the rear slot opening of the adjacent first lifting tank 7. During the upward movement of the first lifting tank 7 close to the guiding groove 3, the cooperation of the second chute 31, the second slider 17, the second baffle 16, and the second partition 18 keeps the first lifting tank 7 sealed, thus ensuring that the fish and water can normally enter the guiding groove 3 through the first lifting tank 7, and further ensuring that the fish can smoothly enter the upstream of the dam body 1.

[0040] Preferably, the bottom surfaces of the first tank body 7-1, the second tank body 8-1, and the guiding groove body 3-1 are all set as inclined surfaces that slope backward, so as to ensure the smooth flow of fish and water during the lifting process.

[0041] A plurality of overflow grooves 2 are provided on the dam body 1, so that the fish upstream of the dam can swim to the downstream of the dam body 1 through the overflow grooves 2.

[0042] The working method of the present utility model is as follows:

[0043] First, fill the bait storage box 23 with bait. When fish migrate downstream of the dam body 1, they are attracted by the smell of the bait in the bait storage box 23 and swim to a position above the second lifting groove 8.

[0044] Turn on the second solenoid valve 22 below the second lifting groove 8. At this time, the water stored upstream of the dam body 1 enters the sleeve 5 through the connecting pipe 11 and this second solenoid valve 22 under the action of water pressure, pushing the corresponding piston 21 to rise, and then driving the second lifting groove 8 to rise through the corresponding rod 6.

[0045] The second lifting groove 8 moves along the first partition plate 15 on the nearby first lifting groove 7, preventing the water and fish in the second lifting groove 8 from detaching from the second lifting groove 8 after the second lifting groove 8 leaves the water surface, thus realizing the rise of the fish group driven by the second lifting groove 8. During the rise of the second lifting groove 8, the water above the second lifting groove 8 can be discharged through the two second filter screens 24, preventing the water flow change above the second lifting groove 8 from disturbing the fish group. During the rise of the second lifting groove 8, the water passing through the water leakage hole 25 squeezes the sealing plate 26, causing the sealing plate 26 to slide downward along the connecting rod 29, and then the water leakage hole 25 is exposed, enabling the water above the second lifting groove 8 to flow out through the water leakage hole 25 and the gap between the second lifting groove 8 and the sealing plate 26, further reducing the water flow degree above the second lifting groove 8 and preventing the fish group from being disturbed; when the second lifting groove 8 stops rising, the water on the second lifting groove 8 acts under inertia, and the pressure of the water on the second lifting groove 8 on the sealing plate 26 decreases. At this time, the spring 30 pushes the sealing plate 26 to rise, realizing the sealing of the water leakage hole 25 at the bottom of the second lifting groove 8.

[0046] When the second lifting groove 8 abuts against the nearby first baffle 14, with the rise of the second lifting groove 8 and the sliding between the first slider 13 and the first chute 12, the first baffle 14 rises. At this time, the water and fish in the second lifting groove 8 flow into the first lifting groove 7 under the action of the inclined plane.

[0047] Then, turn on the second solenoid valve 22 corresponding to the first lifting groove 7, and make the first lifting groove 7 rise through the corresponding sleeve 5, piston 21 and rod 6. During the rise of the first lifting groove 7, under the action of gravity, the first baffle 14 gradually resets to seal one end of the first lifting groove 7, and the other end of the first lifting groove 7 is also in a sealed state under the action of the nearby first partition plate 15, thus realizing the further lifting of the fish group and water through the first lifting groove 7.

[0048] Repeat the above steps until the water and fish group enter the guide groove 3 and then flow to the upstream position of the dam body 1 through the guide groove 3, realizing the process of assisting the fish group to migrate.

[0049] After the water and fish schools are lifted in multiple first lifting grooves 7 and second lifting grooves 8, the switch of the corresponding first solenoid valve 19 is turned on, and the switch of the corresponding second solenoid valve 22 is turned off. Under the action of gravity, the sleeve rod 6 is driven to descend. At this time, the water in the sleeve 5 is output through the drain pipe 20 and the first solenoid valve 19, realizing the reset of multiple first lifting grooves 7 and second lifting grooves 8 to perform the next lifting of the fish school.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
