Description

Technical Field

[0001] The present invention relates to the technical field of river regulation, in particular to an ecological river regulation structure for water conservancy projects. Background Art

[0002] In the construction of modern water conservancy projects, it is necessary to respect the natural river flow and carry out river channel regulation in a way close to nature to protect the ecological integrity of the river channel. In the process of regulating ecological river channels, placing fallen trees in the river channel is a core element in restoring the river ecosystem. The lack of fallen trees in the river channel can easily hinder fish migration, and the single horizontal structure of the river channel will lead to increased riverbank erosion, and the vertical exchange in the river channel will stagnate, causing the exchange between surface water and groundwater to be disconnected. After simulating the introduction of fallen trees in the natural river channel, a slow-flow area is formed on the back of the fallen trees, which can become a refuge for fish and a feeding platform for birds. In addition, fallen trees can intercept some floating objects in the river channel, facilitating river channel cleaning, and the whitewater effect produced when the water impacts the fallen trees can increase dissolved oxygen, making it possible to achieve an ecological river channel.

[0003] Chinese patent application number 201821727741.X discloses "an ecological fallen-wood revetment structure, comprising a wave-breaking structure disposed in water or on a mudflat, with shore anchor piles fixed to the shore disposed on both sides of the wave-breaking structure. The wave-breaking structure comprises a plurality of underwater anchor piles fixed in the water at a predetermined distance from one another, fallen wood being disposed between two adjacent underwater anchor piles and between the wave-breaking structure and the shore anchor piles, anchoring ropes A being disposed between the underwater anchor piles and the fallen wood, and anchoring ropes B being disposed between the shore anchor piles and the fallen wood. The present invention has a novel structure and is simple to operate. It can reduce wind and wave erosion of the revetment, block sediments on the revetment bank, prevent sediment loss on the revetment bank, and thus maintain the revetment."

[0004] This technical solution only solves the problem that the erosion area in the ecological revetment is easily damaged. However, in the construction of modern water conservancy projects, placing traditional wood in the river channel is not only difficult to transport and construct, but also affects the landscape. In addition, traditional wood has poor corrosion resistance and is difficult to maintain in the ecological river channel for a long time.

The bottom ends are respectively inserted and mounted in the middle of the top ends of the two fixed covers 302, and the bottom ends are respectively fixedly mounted in the middle of the two venturi tubes 303 by insertion. There are two anti-blocking heads 305, which are respectively fixedly mounted on the ends of the two air inlet pipes 304 away from the venturi tubes 303.

[0037] The venturi tube 303 is placed through the connecting frame 301, and then the venturi tube 303 is fixed to the connecting frame 301 through the fixing cover 302. The air inlet pipe 304 adopts a U-shaped structure with an anti-clogging head 305 to prevent large-volume debris from entering the air inlet pipe 304, so as to prevent the air inlet pipe 304 from being blocked. The pressure difference of the water flow entering the venturi tube 303 forms a negative pressure at the neck of the venturi tube 303, and the air on the surface of the river is sucked into the venturi tube 303 through the air inlet pipe 304 and discharged with the water flow in the venturi tube 303, so that the dissolved oxygen content in the discharged water is increased, so as to facilitate the survival of fish and benthic organisms and improve biodiversity.

[0038] In other aspects, this embodiment also provides a conduction mechanism 4 for preventing the venturi tube 303 from being blocked, such as Figure 1 、 Figures 4 to 6 As shown, the conducting mechanism 4 includes a conducting rod 415 . There are two conducting rods 415 , which are respectively arranged inside the two venturi tubes 303 .

[0039] In this embodiment, Figures 4 to 6As shown, the conduction mechanism 4 includes a water inlet 401, a first support frame 402, a first rotating shaft 403 and a water wheel 404.

[0040] When the water flows onto the guide plate 201 , part of the water flows into the water inlet 401 and drives the water wheel 404 to rotate, and drives the first rotating shaft 403 to rotate through the water wheel 404 .

[0041] In this embodiment, Figures 4 to 6 As shown, the conducting mechanism 4 includes a first gear 405, a second support frame 406, a second rotating shaft 407 and a second gear 408. There are two first gears 405, which are fixedly sleeved on both ends of the first rotating shaft 403 respectively. The second support frame 406 is fixedly mounted on the side of the first support frame 402 away from the guide plate 201. The second rotating shaft 407 is movably mounted on the end of the second support frame 406 away from the first support frame 402. There are two second gears 408, which are fixedly sleeved on both ends of the second rotating shaft 407 respectively. The two second gears 408 are respectively connected to the two first gears 405 by meshing.

[0042] The first gears 405 at both ends are driven to rotate by the first rotating shaft 403. When the first gear 405 rotates, the second gear 408 is driven to rotate slowly. The second rotating shaft 407 is supported and installed by the second supporting frame 406. The second gear 408 is installed through the second rotating shaft 407, and the two second gears 408 can rotate synchronously.

[0043] In this embodiment, Figures 4 to 6 As shown, the conduction mechanism 4 includes a third support frame 409, a reciprocating groove 410 and a reciprocating rod 411. There are two third support frames 409, which are fixedly mounted on the top side of the base plate 1 and located between the second gear 408 and the main fixed cylinder 202. The reciprocating groove 410 is opened at the top of the third support frame 409. The reciprocating rod 411 is movably mounted on the top of the two third support frames 409 and is inserted into the two reciprocating grooves 410.

[0044] The reciprocating rod 411 is supported by the third support frame 409 , and the reciprocating rod 411 can translate at the top end of the third support frame 409 through the reciprocating slot 410 .

[0045] In this embodiment, Figures 4 to 6As shown, the conducting mechanism 4 includes a connecting arm 412, a connecting rod 413 and a connecting cylinder 414. There are two connecting arms 412, and one end close to the guide plate 201 is movably mounted on the side of the two second gears 408 away from the second support frame 406. The ends of the two connecting arms 412 away from the guide plate 201 are movably sleeved on the reciprocating rod 411. There are two connecting rods 413, and the ends away from the guide plate 201 are fixedly mounted on the side walls of the two side fixed cylinders 203. There are two connecting cylinders 414, and they are fixedly mounted on the ends of the two connecting rods 413 away from the side fixed cylinders 203. There are two conducting rods 415, and they are movably mounted in the two connecting cylinders 414, and the ends close to the guide plate 201 are fixedly mounted on the two ends of the reciprocating rod 411. A conducting head is provided at one end of the conducting rod 415 located in the venturi tube 303.

[0046] The connecting arm 412 is driven to perform reciprocating motion by the second gear 408. When the connecting arm 412 moves away from the guide plate 201, the reciprocating rod 411 is driven to move in the reciprocating groove 410 toward the venturi tube 303. The reciprocating rod 411 drives the conducting head on the conducting rod 415 to move toward the neck of the venturi tube 303, so that water plants and other debris accumulated in the venturi tube 303 due to long-term use are conducted, so that the debris can be discharged from the venturi tube 303 with the water flow, so that the venturi tube 303 can be prevented from being blocked.

[0047] Working Principle: When using the present invention, the entire structure is placed in the river channel so that the outer side wall of the guide plate 201 faces the direction of water flow. Then, the main root pile 204 is inserted into the main fixing tube 202, and the side root pile 205 is inserted into the side fixing tube 203 to fix the entire structure in the river channel.

[0048] The water flow is diverted and directed by the guide plate 201, and the water flow is blocked by the guide plate 201, so that the water flow forms a Karman vortex, thereby forming a slow flow area on the back of the guide plate 201. The slow flow area on the back of the guide plate 201 can be used as a refuge for fish in the ecological river channel, and aquatic plants are planted in the planting troughs 208 provided in the slow flow area to improve the ecological integrity of the ecological river channel.

[0049] The water flow diverted by the guide plate 201 is accelerated and enters the venturi tube 303. The pressure difference of the water flow entering the venturi tube 303 creates a negative pressure at the neck of the venturi tube 303. Air on the surface of the river is sucked into the venturi tube 303 through the air inlet pipe 304 and discharged with the water flow in the venturi tube 303. This increases the dissolved oxygen content in the discharged water, which facilitates the survival of fish and benthic organisms, thereby improving biodiversity.

[0050] When the water flows on the guide plate 201, part of the water flows into the water inlet 401 and drives the water wheel 404 to rotate. The water wheel 404 drives the first rotating shaft 403 to rotate, so that the first gears 405 at both ends of the first rotating shaft 403 rotate simultaneously with the first rotating shaft 403. When the first gear 405 rotates, it drives the second gear 408 to rotate slowly. When the second gear 408 rotates, each rotation drives the connecting arm 412 to complete a reciprocating motion. When the connecting arm 412 moves in the direction away from the guide plate 201, it drives the reciprocating rod 411 to move in the reciprocating groove 410 toward the venturi tube 303, and the reciprocating rod 411 drives the conducting head on the conducting rod 415 to move toward the neck of the venturi tube 303, so that the water plants and other debris accumulated in the venturi tube 303 due to long-term use are conducted, so that the debris can be discharged from the venturi tube 303 with the water flow, so that the venturi tube 303 can be prevented from being blocked.
