[0020] (III) Beneficial effects

[0021] Compared with the prior art, the present invention provides a combined ecological restoration device for river basin water environment management, which has the following beneficial effects:

[0022] 1. When the present invention is in use, multiple plant racks can be arranged into multiple groups according to the same number until a suitable width is reached. Retaining walls and tail weirs are used at both ends to achieve relative sealing, thereby forming a water retaining dam structure, so that a certain water level difference is formed between the upstream and downstream under the action of the water retaining dam structure. After the water level rises, it first enters the planting rack from the canal mouth, and then overflows into the water storage channel after the water level in the planting rack rises. After the water level in the water storage channel rises, it is discharged from the overflow port on the tail weir to the downstream. In this way, the water level is raised after interception, and the water flow can be diverted into thin streams during the overflow process, and the water flow can also impact the low water surface when falling, increasing the contact area and time with the air. The hinged components arranged in the plant rack can form a multi-layer structure inside it, and multiple channels can be formed when forming a row, so that multiple spaces can be formed inside it for planting emergent plants, diving plants and submerged plants, and the space in the middle part can be selected as a breeding area, and the area of ​​the breeding area can be adjusted according to demand to breed more fish.

[0023] 2. The hinge assembly provided in the present invention can realize synchronous folding of the two gantries through the two meshing arc-shaped racks when in use, and the parallel movement of the two side panels can be guaranteed during synchronous folding. During installation, the lower end of the side panel is inserted into the riverbed mud layer, and the close fit of the folded edges can realize that a plurality of plant racks form a relatively sealed space, and the aperture of the mesh plate can be selected according to demand, especially the mesh plate in the breeding area can select a small-aperture plate, so that the fish eggs produced in the breeding area are blocked from the outside world, so that the water flow can only overflow into the water storage channel through the upper end, and the plurality of triangular openings provided during the overflow process can form a plurality of thin streams of water, and the position of the overflow port is lower than the position of the triangular opening, so that the thin stream after diversion through the triangular opening can impact the pages in the water storage channel to generate bubbles, so that the oxygen content in the water can be increased, and after the assembly is completed, the U-shaped clamping piece can not only fix the water diversion plate in the limit clamping slot, but also connect and fix the adjacent side panels through the U-shaped slot, the positioning slot and the positioning unit.

[0024] 3. The present invention is provided with a flow disturbance mechanism. When in use, the water retaining dam composed of the retaining wall and the tail weir makes the upstream water flow only overflow and discharge. Therefore, the water level of the downstream is much lower than the upstream water level, thereby forming a liquid level difference. Part of the water in the water storage channel is discharged through the overflow port. Under the action of the gravity of the water flow, the water flow with a water flow velocity is quantitatively discharged through the drain pipe and the constriction mouth. When the water flows, it drives the first impeller and the second impeller to rotate. When the first impeller rotates, it drives the hollow shaft to rotate the retaining frame. When the retaining frame rotates, it drives the triangular plate to make a circular motion. At this time, the triangular plate can be used to stir the water flow at the overflow nozzle, so that the water flow forms a vortex at the overflow nozzle, so that the water can be further stirred when overflowing to increase the contact with the air. In addition, when the second impeller rotates, it drives the vertical shaft to rotate the pump wheel. When the pump wheel rotates, the water in the flow limiting pipe is pushed upward to accelerate the discharge. At this time, part of the water can be run into the air. Under the action of gravity, the water falls freely and hits the water surface to form small bubbles in the water, so that the water body is broken up again by the disturbance during the movement and fully contacts the air.

A plurality of hinged components are arranged in the planting rack, and a plurality of channel openings 3 are arranged at the upper end of the retaining wall 1, and the channel openings 3 are connected to the plant rack, and a plurality of overflow openings are arranged at the upper end of the tail weir 5, and the overflow openings are connected to the water storage channel;

[0042] The retaining wall 1 is composed of a plurality of baffles, and right-angled notches are provided at the corners of the plurality of baffles, and the right-angled notches on two adjacent baffles together form a channel outlet 3. The tail weir 5 is composed of a plurality of tail plates, and notches are provided at the upper ends of the plurality of enclosures, and the notches on the two adjacent enclosures together form an overflow outlet. The side walls of the retaining wall 1 and the tail weir 5 are fixedly connected with a plurality of I-shaped steels 2, and two I-shaped steels 2 are symmetrically arranged on one side of each baffle of the retaining wall 1, and one I-shaped steel 2 is arranged at the joint of two adjacent tail plates of the tail weir 5. A plurality of shells 10 are arranged on one side of the tail weir 5, and spoiler assemblies are arranged in the plurality of shells 10, and the spoiler assemblies are fixed on one side of the tail plate. The spoiler assemblies convert the water level difference in the water storage channel into mechanical energy, and use the mechanical energy to stir the water discharged from the overflow outlet to fully contact with the air to achieve aeration.

[0043] When the present invention is in use, multiple plant racks can be arranged into multiple groups according to the same number until a suitable width is reached. The retaining wall 1 and the tail weir 5 are used at both ends to achieve relative sealing, thereby forming a water retaining dam structure. The width of the water retaining dam structure matches the width of the water surface, so that water can only overflow through the upper end of the water diversion plate 4, so that a certain water level difference is formed between the upstream and downstream under the action of the water retaining dam structure. After the water level rises, it first enters the planting rack from the canal mouth 3. After the water level in the planting rack rises, it overflows into the water storage channel. After the water level in the water storage channel rises, it is discharged from the overflow port on the tail weir 5 to the downstream. In this way, the water level is raised through interception, and the water flow can be diverted into thin streams during the overflow process. When the water flow falls, it can also cause impact on the low water surface, thereby increasing the contact area and time with the air.

[0044] like Figure 2As shown, the hinged components arranged in the plant rack can form a multi-layer structure inside the plant rack, and multiple channels can be formed when a row is formed, so that multiple spaces can be formed inside the plant rack for planting emergent plants, submerged plants and submerged plants. The space in the middle part can be selected as a breeding area, and the area of ​​the breeding area can be adjusted in size according to demand to breed more fish, such as scavengers. The scavenger is an omnivorous fish that relies on sucking algae, benthic animals and garbage in the water.

[0045] Embodiment 2: Based on embodiment 1, the difference is that;

[0046] See attached Figure 2 and Figure 3 The hinge assembly includes a center plate 20 and two gantries 21. The lower end of the center plate 20 is fixedly connected to two rectangular plates.

A mesh plate 22 is fixedly connected inside the gantry 21, and the opposite sides of the center plate 20 are fixedly connected with inclined plates 23, which are in contact with the side walls of the mesh plate 22. Multiple hinge assemblies divide the interior of the planting frame into a water-emergent plant planting area, a submerged plant planting area, a breeding area, and a submerged plant planting area from top to bottom.

[0047] The two opposite sides of the two folding edges 16 are fixedly connected to the limit plate 12, and the limit plate 12 and one side of the side plate 17 form a limit slot.

[0048] The hinge assembly provided in the present invention can realize synchronous folding of the two gantries 21 by means of the two meshing arc-shaped racks 25 when in use, and can ensure the parallel movement of the two side panels 17 when synchronously folding. When installed, the lower ends of the side panels 17 are inserted into the riverbed mud layer, and the close fit of the folded edges 16 can realize that a plurality of plant racks form a relatively sealed space, and the aperture of the mesh plate 22 can be selected according to demand, especially the mesh plate 22 in the breeding area can be selected with a small aperture, so that the fish eggs produced in the breeding area are blocked from the outside world. The water can only overflow into the water storage channel through the upper end, and the multiple triangular openings 15 set during the overflow process can make the water form multiple thin streams, and the position of the overflow port is lower than the position of the triangular opening 15, so that the thin streams after being diverted by the triangular opening 15 can impact the pages in the water storage channel to generate bubbles, thereby increasing the oxygen content in the water. After the assembly is completed, the set U-shaped clip 11 can not only fix the water diversion plate 4 in the limit slot, but also connect and fix it with the adjacent side plate 17 through the U-shaped slot 13, the positioning slot 14 and the positioning portion 19.

[0051] A vertical shaft 31 is rotatably connected to the hollow shaft 7 through a sealed bearing, the lower end of the vertical shaft 31 extends into the housing 10 and is fixedly connected to a second impeller 33 identical to the first impeller 34, the upper end of the vertical shaft 31 extends into the retaining frame 38 and is fixedly spliced ​​with a pump wheel 41, the side wall of the pump wheel 41 is sleeved with a limiting flow tube 37, the lower end of the limiting flow tube 37 is obliquely fixedly connected to a plurality of blades 42, the lower ends of the plurality of blades 42 are fixedly connected to the lower end of the retaining frame 38, the side walls of the first impeller 34 and the second impeller 33 are each provided with two symmetrically distributed guide covers 35, the plurality of guide covers 35 are fixed in the housing 10 to form two annular channels, the two annular channels are respectively matched with the positions of the arc-shaped openings 24 on the two constriction portions 9.

[0052] The spoiler mechanism provided in the present invention, when in use, because the retaining wall 1 and the tail weir 5 form a water retaining dam so that the upstream water flow can only overflow and discharge, the water level of the downstream is much lower than the upstream water level, thereby forming a liquid level difference, and part of the water in the water storage channel is discharged through the overflow port, and under the action of the water flow gravity, the water flow with the water flow velocity is quantitatively discharged through the drainage pipe 32 and the constriction part 9, and the water flow drives the first impeller 34 and the second impeller 33 to rotate when the water flow flows, and the first impeller 34 drives the hollow shaft 7 to rotate the retaining frame 38 when the first impeller 34 rotates, and the retaining frame 38 drives the triangular plate 39 when the retaining frame 38 rotates. The water at the overflow nozzle 6 makes a circular motion. At this time, the triangular plate 39 can be used to stir the water flow at the overflow nozzle 6, so that the water forms a vortex at the overflow nozzle 6, so that the water can be further stirred when overflowing to increase the contact with the air. In addition, when the second impeller 33 rotates, it drives the vertical shaft 31 to rotate the pump wheel 41. When the pump wheel 41 rotates, it pushes the water in the flow limiting pipe 37 to accelerate the discharge upward. At this time, part of the water can be run into the air. Under the action of gravity, the water falls freely and hits the water surface to form small bubbles in the water, so that the water body is broken up again by the turbulence during the movement and fully contacts the air.
