Description

Technical Field

[0001] The present invention relates to the technical field of drawdown zone restoration, and in particular to a self-filtering light-tracking photovoltaic device and method for reservoir bank protection. Background Art

[0002] In recent years, with the continuous development of solar energy technology, distributed photovoltaic power generation systems have been widely used in many fields. With the further promotion of the integrated development of more fields and new energy, deploying a distributed photovoltaic power generation system on the reservoir bank can not only effectively utilize idle resources, but also provide clean and renewable energy for reservoir bank facilities.

[0003] The defects existing in the existing slope photovoltaic panel structure are as follows: 1. Comparative document CN220527980U discloses a slope photovoltaic system. The protected claim is "The embodiment of the present application provides a slope photovoltaic system, including: a drainage channel, multiple groups of drainage channels are arranged at intervals along the first direction on the slope, and the drainage channels are used to drain road surface water; a water baffle, the water baffle is laid at the top end of the slope close to the adjacent two groups of drainage channels, and the water baffle is used to guide the road surface water to drain into the drainage channel; a bracket, the bracket is arranged on the side of the adjacent two groups of drainage channels away from the slope; a lightweight photovoltaic module, the lightweight photovoltaic module is bonded to the side of the bracket away from the drainage channel. In this way, since the drainage channel is provided on the slope and the bracket is erected on the drainage channel, compared with the slope with loose soil, the bearing capacity of the drainage channel is greater, so that the bracket can be firmly fixed; in addition, since the water baffle is laid at the top end of the slope close to the adjacent two groups of drainage channels, the road surface water can be guided to drain from the drainage channel, avoiding the erosion of the slope by the road surface water and further improving the overall installation reliability of the slope photovoltaic system." However, since the angle of the photovoltaic panel does not change after being arranged on the slope, the power generation efficiency is relatively low in some places with insufficient sunlight.

[0004] 2. The comparative document CN218587111U discloses a multi-angle sunlight-tracking photovoltaic power generation device. The claimed right is "The present utility model discloses a multi-angle sunlight-tracking photovoltaic power generation device, including a photovoltaic panel and a support base. One side of the photovoltaic panel is fixedly connected with a support block, a sliding groove is formed on the surface of the photovoltaic panel, a sliding mechanism is arranged on one side of the photovoltaic panel, the inner wall of the support base is fixedly connected with a battery box, a battery is fixedly connected to the inner wall of the battery box, and a rotating column is fixedly connected to the top of the support base. The present utility model relates to the technical field of photovoltaic power generation. For this multi-angle sunlight-tracking photovoltaic power generation device, by starting the motor, one end of the output shaft of the motor drives the first bevel gear to start rotating through a coupling. The rotation of the first bevel gear drives the second bevel gear to start rotating. The rotation of the second bevel gear drives the rotating rod to start rotating. The surface of the rotating rod starts to rotate inside the rotating column. The rotation of the rotating rod drives the concave block to start rotating, thereby causing the photovoltaic panel to start rotating." However, the current power generation efficiency of the photovoltaic panel is not very high, and this device needs to continuously detect the angle of sunlight to adjust the rotation of the motor, resulting in less actual power storage of the photovoltaic panel.

[0005] 3. The comparative document CN210671466U discloses a slope greening vegetation. The claimed right is "The present utility model discloses a slope greening vegetation belt, including a slope and a support. A vegetation belt is arranged on the support. An irrigation branch pipe penetrates through the vegetation belt. A water tank is arranged at the bottom of the support. A recyclable water tank is arranged below the water tank. The recyclable water tank is connected with an irrigation water pipe. The irrigation water pipe is perpendicular to the vegetation belt and a water outlet is reserved at the intersection position with the vegetation belt to communicate with the irrigation branch pipe. An irrigation control device is also arranged on the surface of the recyclable water tank. An irrigation branch pipe is arranged inside the vegetation belt, which can fully irrigate the vegetation belt. A non-woven fabric is arranged outside the vegetation belt to keep the shape of the plant substrate stable. The plant substrate can maintain the water source and nutrients required for plant growth, improving the survival rate of plants; through the fixed connection setting of the slope and the support, the vegetation belt arranged on the support, and the plant layer growing on the vegetation belt and adhering to the slope surface, soil erosion of the slope can be prevented." However, after long-term succession of plants on the slope, plants with relatively high growth heights will grow out, blocking the photovoltaic panel and affecting its power generation efficiency.

[0006] Photovoltaic has been applied to a certain extent in the field of slopes. However, due to the certain angle of the slope itself and the continuous movement of the sun, the actual power generation efficiency of the photovoltaic panel cannot reach the maximum; on some reservoir banks, the plants grow too lushly. After long-term plant succession when the photovoltaic panel is installed on the reservoir bank, the vegetation will grow and cover the photovoltaic panel, affecting its light-emitting efficiency; under human activities, the water in the reservoir is polluted to varying degrees, including but not limited to heavy metal pollution, polycyclic aromatic hydrocarbon pollution, and nitrogen and phosphorus pollution. Summary of the Invention

[0007] The object of the present invention is to overcome the above deficiencies and provide a self-filtering light-tracking photovoltaic device and method for reservoir bank protection to solve the problems raised in the background art.

[0008] To solve the above technical problems, the technical solution adopted by the present invention is: a self-filtering light-tracking photovoltaic device for reservoir bank protection, including a rotating light-tracking photovoltaic device laid on the reservoir bank slope. The input end of the rotating light-tracking photovoltaic device is connected to the output end of the screw conveyor through a speed reducer, and the top end of the screw conveyor is communicated with the filtering pool.

[0009] Preferably, the rotating light-tracking photovoltaic device includes a photovoltaic panel and a support plate hinged to each other. A support rod with an adjustable length is provided between the support plate and the photovoltaic panel. The bottom of the support plate is connected to a transmission shaft, and the input end of the transmission shaft is connected to the output end of the screw conveyor through a speed reducer.

[0010] More preferably, the photovoltaic panel and the support plate are hinged by a hinge.

[0011] More preferably, a first gear is arranged below the transmission shaft, and the input end of the first gear is connected to the output reduction gear of the speed reducer.

[0012] More preferably, a rotating blade is arranged in the middle of the transmission shaft, a net-shaped disc housing is arranged below the rotating blade, the lower part of the transmission shaft and the first gear are both located in the net-shaped disc housing, and the net-shaped disc housing is fixedly connected to the anchor rod below.

[0013] Preferably, the screw conveyor includes an energy supply device and a water delivery pipe. A rotating shaft is arranged inside the water delivery pipe, and spiral blades are arranged on the surface of the rotating shaft. The lower end of the rotating shaft is connected to the output end of the energy supply device, and both the top and bottom of the rotating shaft are rotatably connected to the water delivery pipe through bearings. A plurality of gear two with a hollow structure are fixedly arranged on the outer circumference of the rotating shaft. A notch is opened on the upper surface of the water delivery pipe corresponding to the gear two, and the gear two meshes with the input reduction gear of the speed reducer.

[0014] More preferably, the energy supply device includes a rotating impeller. A protective housing with a hollow structure is sleeved outside the rotating impeller. The central shaft of the rotating impeller is arranged inside the protective housing and is rotatably connected thereto. A gear four is arranged outside the central shaft of the rotating impeller, and the gear four meshes with a gear three arranged at the lower part of the rotating shaft.

[0015] More preferably, the reduction ratio of the speed reducer is set as: every 24 hours, the output reduction gear of the speed reducer makes the first gear rotate 360°.

[0016] Preferably, the filtering pool is sequentially provided with a fine sand layer, an activated carbon layer and a fluffy cotton layer from top to bottom. Each layer is isolated by a gauze, and a hole is reserved below the filtering pool for the filtered water to flow into the reservoir bank.

[0017] In addition, the present invention also discloses a usage method of the above self-filtering light-tracking photovoltaic device for reservoir bank protection, which includes the following steps: Step 1: Clean the gravel and weeds on the reservoir bank and detect the position of the lowest water level line of the reservoir bank; Step 2: When the water level is at its lowest, arrange the rotating light-tracking photovoltaic device on the reservoir bank through anchor rods; Step 3: Arrange a screw conveyor device on one side of the rotating light-tracking photovoltaic device, ensure that the energy supply device at the bottom of the screw conveyor device and the pipe orifice below the water delivery pipe are immersed below the lowest water level line and set up brackets below for fixation, and ensure that the gear 2 of the screw conveyor device corresponds to the position of the rotating light-tracking photovoltaic device; Step 4: Add a speed reducer between the rotating light-tracking photovoltaic device and the screw conveyor device to connect the two, and build a filter pool on the top of the screw conveyor device; Step 5: After the device is assembled, pre-adjust the angle of the photovoltaic panel of the rotating light-tracking photovoltaic device to make it receive light to the greatest extent; Step 6: Due to the action of the water flow in the reservoir, the rotating impeller of the energy supply device rotates, and through the gear 4, the gear 3 arranged at the lower part of the rotating shaft rotates, so that the rotating shaft drives the spiral blade to rotate. Through the screw conveying process, the water in the reservoir is transported to the filter pool, and at the same time drives the gear 2 to rotate; Step 7: Pre-adjust the reduction ratio of the speed reducer so that when the gear 2 of the screw conveyor device rotates for one day, it drives the gear 1 of the rotating light-tracking photovoltaic device to rotate one week. The gear 1 drives the photovoltaic panel to rotate with time through the transmission shaft, reaching one rotation per day. The photovoltaic panel rotates with the angle of the sun's rotation to maximize the reception of light and increase the power generation efficiency of the photovoltaic panel; Step 8: When the plants on the reservoir bank grow too tall, they will extend into the meshes on the upper part of the mesh disc housing. The gear 1 drives the rotating blade to rotate slowly through the transmission shaft, and when the top of the plant just passes through the mesh, it is cut off by the shear force between the blade and the mesh disc, so as to prevent the plants from blocking the photovoltaic panel due to excessive height; Step 8: The water in the filter pool is filtered through multiple layers and then flows into the reservoir bank through the holes below the filter pool to irrigate the vegetation on the reservoir bank; Step 9: Place a cover plate on the top of the filter pool and make marks to prevent people from accidentally falling in.

[0018] Advantages of the present invention: 1. The water level lines of the reservoir bank vary greatly in different seasons. Taking the Three Gorges Reservoir Area as an example, in summer, the water level line reaches its lowest point, and combined with dry weather, it is difficult for plants to grow; the screw conveyor device can transport the water in the reservoir area to the filter storage pool to irrigate the plants and maintain the soil humidity.

[0019] 2. The screw conveyor of the present invention, under the action of water flow by the energy supply device, rotates the impeller to convey water, realizing the process of automatically and slowly conveying water to the filtration reservoir without electricity.

[0020] 3. Due to the influence of ship driving in the reservoir area and the incomplete combustion emissions of biomass fuels on the reservoir bank, water pollution may be caused; the screw conveyor continuously conveys the water in the reservoir area to the filtration reservoir under the action of water flow, and then most of the pollutants in the water are removed through filtration by activated carbon and the like, which can purify the water body.

[0021] 4. The present invention sets the angle of the photovoltaic panel of the rotating light-tracking photovoltaic device to face the angle of maximum light reception, adjusts the reduction gear so that the second gear of the screw conveyor rotates one day to drive the first gear of the rotating light-tracking photovoltaic device to rotate one week; the first gear makes the photovoltaic panel rotate with time through the transmission shaft, and the photovoltaic panel rotates one week a day almost along with the angle of the sun's rotation, which can make the photovoltaic panel receive light maximally and increase the power generation efficiency of the photovoltaic panel.

[0022] 5. When the plants on the reservoir bank grow too high and will reach the photovoltaic panel to block it, they extend into the meshes on the upper part of the net-shaped disc housing, and the first gear makes the rotating blade rotate slowly through the transmission shaft. When the top of the plant passes through the mesh, it is cut off by the shear force between the blade and the mesh disc, reducing the influence of the growth of plants around the photovoltaic panel on the coverage of the photovoltaic panel.
