Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of river ecological restoration, and particularly relates to a river and lake ecological restoration system. Background Art
[0002] River ecological restoration refers to using the principles of the ecosystem and adopting various methods to repair the biological groups and structures of the damaged water ecosystem, reconstruct a healthy aquatic ecosystem, repair and strengthen the main functions of the water ecosystem, and enable the ecosystem to achieve a virtuous cycle of overall coordination, self-maintenance, and self-succession.
[0003] An artificial lake is a lake dug out by people in a planned and purposeful manner and is generated under a non-natural environment, including landscape lakes and large reservoirs. Artificial lakes have the advantages of optimizing the urban environment, increasing the urban affinity, and reducing dust weather. Therefore, when a river flows through a city, a section of the river is often taken, and dams are set at the upstream and downstream of the river to intercept water, so that a certain section of the river always stores an appropriate amount of river water to form an urban artificial lake. However, a large amount of debris will accumulate on the water surface of the artificial lake in the long term and gather downstream, seriously affecting the urban beauty and the water ecosystem. Currently, it is common for workers to regularly salvage the debris floating on the water surface by boat, which is highly dangerous for workers and has a low salvage efficiency. Summary of the Invention
[0004] The purpose of the present invention is to overcome the problems in the prior art and provide a river and lake ecological restoration system.
[0005] The present invention provides a river and lake ecological restoration system, including: a garbage pushing and transporting structure and a storage area. The garbage pushing and transporting structure includes a rotating shaft and a spiral blade. The rotating shaft is fixedly connected to the inner rotating surface of the spiral blade, and both ends of the rotating shaft are rotatably arranged on the river bank, and a part of the rotating shaft is immersed in the water surface; the storage area is arranged on the side of the river bank, and the opening of the storage area is located in the upstream area close to the garbage pushing and transporting structure.
[0006] Preferably, a dam is provided below the garbage pushing and transporting structure. The dam is connected to the river bank on the side away from the storage area, and the side of the dam close to the storage area is lower than the side of the dam away from the storage area; the blade radius of the spiral blade gradually increases from the direction of the dam towards the storage area.
[0007] Preferably, lifting structures are provided on the side walls of both banks. Each lifting structure includes a vertical plate, an electric telescopic rod, a sliding plate, and a bearing. The vertical plate is fixedly connected to the river bank. A chute is provided on the upper end surface of the vertical plate. The bottom surface of the chute is fixedly connected to the fixed end of the electric telescopic rod. The moving end of the electric telescopic rod is fixedly connected to the lower end of the sliding plate. The sliding plate is slidably arranged in the chute. The upper end of the sliding plate is fixedly connected to the outer ring of the bearing. The inner ring of the bearing is fixedly connected to the end of the rotating shaft. A liquid level sensor is vertically arranged on the side wall of the river bank. The liquid level sensor sends liquid level height data to the controller, and the controller outputs a command for whether the electric telescopic rod extends or retracts, so that the position of the rotating shaft is consistent with the liquid level height.
[0008] Preferably, the upper end of the sliding plate on the lifting structure away from the storage area is fixedly connected to a motor bracket. A motor is fixedly arranged on the motor bracket. The output shaft of the motor is fixedly connected to the rotating shaft. The motor is electrically connected to the controller, and the controller controls the rotation of the motor.

[0012] Preferably, corrosion-resistant materials are provided on the surfaces of the rotating shaft and the spiral blade.
[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: When the river and lake ecological restoration system of the present invention is in use, during the process of water body flow, the lower blades of the spiral blade are pushed, and the water body generates a moment on the spiral blade, so that the spiral blade can rotate without the action of torque. During the rotation of the spiral blade and the rotating shaft, not only can it block the sundries on the water surface, but also the spiral blade can push the sundries on the water surface to the right side (storage area). The sundries enter the storage area from the opening. Workers only need to salvage the sundries in the storage area, avoiding the problem of workers salvaging the sundries floating on the water surface by boat regularly, greatly reducing the danger of workers, ensuring the life safety of workers, and having high salvage efficiency.

[0019] The following describes the specific implementation manners of the present invention in detail, but it should be understood that the protection scope of the present invention is not limited by the specific implementation manners. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.
[0020] A river and lake ecological restoration system provided by the present invention, as Figure 1-2 including: a garbage pushing and transporting structure and a storage area 4. The garbage pushing and transporting structure includes a rotating shaft 1 and a screw blade 2. The rotating shaft 1 is fixedly connected to the inner rotating surface of the screw blade 2, and both ends of the rotating shaft 1 are rotatably arranged on the riverbank 3, and a part of the rotating shaft 1 is immersed in the water surface; the storage area 4 is arranged on the side of the riverbank 3, and the opening of the storage area 4 is located in the upstream area close to the garbage pushing and transporting structure.
[0021] During the process of water flow, the lower blades of the screw blade 2 are pushed, and the water body generates a moment on the screw blade 2, enabling the screw blade 2 to rotate without the action of torque. During the rotation of the screw blade 2 and the rotating shaft 1, not only does it have a blocking effect on the debris 14 on the water surface, but also the screw blade 2 can push the debris 14 on the water surface to the right (storage area 4). The debris 14 enters the storage area 4 through the opening. Workers only need to salvage the debris in the storage area 4, avoiding the problem of workers regularly salvaging the floating debris on the water surface by boat, greatly reducing the danger to workers, ensuring the safety of workers' lives, and having high salvage efficiency.
[0022] Preferably, as Figure 1-2 a dam 5 is provided below the garbage pushing and transporting structure. The dam 5 is connected to the riverbank 3 on the side far from the storage area 4, and the side of the dam 5 close to the storage area 4 is lower than the side of the dam 5 far from the storage area 4; the blade radius of the screw blade 2 gradually increases from the direction of the dam 5 towards the storage area 4.
[0023] The function of the dam 5 not only has the function of blocking water, but also enables the speed and flow rate of water outflow to be reduced during the dry season. At the same time, it can also cause the debris 14 on the water surface to converge more towards the storage area 4 along with the water flow. When there is more debris 14 converged, the larger blades of the spiral blade 2 have a stronger ability to push the debris 14 to the right, and the ability of the water flow to drive the rotation of the rotating shaft 1 and the spiral blade 2 is also stronger;
[0024] During the flood season, the water flow increases, the water surface rises, and during the process of the water surface rising, part of the dam 5 is gradually submerged. The water surface width increases, and the accumulation width of the debris 14 on the water surface also increases. The increase in the water surface width enables the area where the water flow can drive the spiral blade 2 to increase, and the spiral blade 2 can adaptively push the debris 14 with the increased accumulation width into the storage area 4 together to the right.
[0025] Preferably, as Figure 1-3 Lifting structures are provided on the side walls of both sides of the river bank 3. Each lifting structure includes a vertical plate 6, an electric telescopic rod 7, a sliding plate 8 and a bearing 9. The vertical plate 6 is fixedly connected to the river bank 3. A chute is provided on the upper end surface of the vertical plate 6. The bottom surface of the chute is fixedly connected to the fixed end of the electric telescopic rod 7. The moving end of the electric telescopic rod 7 is fixedly connected to the lower end of the sliding plate 8. The sliding plate 8 is slidably arranged in the chute. The upper end of the sliding plate 8 is fixedly connected to the outer ring of the bearing 9. The inner ring of the bearing 9 is fixedly connected to the end of the rotating shaft 1; A liquid level sensor 10 is vertically arranged on the side wall of the river bank 3. The liquid level sensor 10 sends the liquid level height data to the controller, and the controller outputs a command on whether the electric telescopic rod 7 extends or retracts, so that the position of the rotating shaft 1 is consistent with the liquid level height.
[0026] When the liquid level sensor 10 detects that the water surface rises, the controller controls the two electric telescopic rods 7 to extend simultaneously. The sliding plate 8 moves upward, and the rotating shaft 1 and the spiral blade 2 are lifted, so that the rotating shaft 1 can always be near the water surface. The purpose is to maximize the torque generated when the flow of water drives the spiral blade 2 and maximize the ability to push the debris 14 to the right; When the liquid level sensor 10 detects that the water surface drops, the controller controls the two electric telescopic rods 7 to shorten simultaneously.
[0027] Preferably, as Figure 2-3 The upper end of the sliding plate 8 on the lifting structure far from the storage area 4 is fixedly connected to a motor bracket 11. A motor 12 is fixedly arranged on the motor bracket 11. The output shaft of the motor 12 is fixedly connected to the rotating shaft 1. The motor 12 is electrically connected to the controller, and the controller controls the rotation of the motor 12.
[0028] In the case where the water flow velocity is relatively small during the dry season and the ability of the water flow to drive the rotation of the rotating shaft 1 and the spiral blade 2 is low, the motor 12 is started to increase the ability of the spiral blade 2 to push the debris 14 to the right.
[0029] Preferably, asFigure 1-3 A diversion channel 13 along the direction of the rotating shaft 1 is arranged on the upper surface of the dam 5, and the lower part of the spiral blade 2 is immersed in the diversion channel 13.
[0030] The purpose is to confine the sundries 14 in the diversion channel 13, and the spiral blade 2 can better push the sundries 14 to move.
[0031] Preferably, the motor 12 is a waterproof motor; the bearing 9 is a waterproof sealed bearing.
[0032] Preferably, the diversion channel 13 is gradually bent downward in the direction close to the storage area 4, so that the diversion channel 13 can accommodate the gradually enlarged spiral blade 2.
[0033] Preferably, the surfaces of the rotating shaft 1 and the spiral blade 2 are both provided with corrosion-resistant materials.
[0034] The using method of the river and lake ecological restoration system of the present invention is as follows:
[0035] During the process of water flow, the lower blades of the spiral blade 2 are pushed, and the water body generates a moment on the spiral blade 2, so that the spiral blade 2 can rotate without the action of torque. During the rotation of the spiral blade 2 and the rotating shaft 1, not only does it have a blocking effect on the sundries 14 on the water surface, but also the spiral blade 2 can push the sundries 14 on the water surface to the right (storage area 4), and the sundries 14 enter the storage area 4 from the opening. Workers only need to salvage the sundries in the storage area 4;
[0036] When in the dry season, the outflow speed and flow rate of the water can both decrease, and at the same time, the sundries 14 on the water surface can also be converged more towards the storage area 4 along with the water flow. When there are more converged sundries 14, the larger blades of the spiral blade 2 can push the sundries 14 to the right more strongly, and the water flow can also drive the rotating shaft 1 and the spiral blade 2 to rotate more strongly;
[0037] When in the flood season, the water flow increases, the water surface rises, and during the process of the water surface rising, part of the dam 5 is gradually submerged, the water surface width increases, and the accumulation width of the sundries 14 on the water surface also increases. The increase in the water surface width enables the area of the water flow that can drive the spiral blade 2 to increase, and the spiral blade 2 can adaptively push the sundries 14 with the increased accumulation width together to the right into the storage area 4.
[0038] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
