[0019] Figure 2 1 is a top view of the photovoltaic sand control system in an embodiment of the present invention. DETAILED DESCRIPTION

[0020] The present invention is further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0021] like Figure 1 to Figure 2As shown, an embodiment of the present invention provides a photovoltaic sand control system, including: a photovoltaic device, which includes a photovoltaic panel 1 and a photovoltaic bracket, the photovoltaic bracket includes a top frame 2 and a bottom bracket 6, the top frame 2 is formed by four frame structures connected in sequence, the frame structure includes a pair of wall panels 3 arranged opposite to each other, the pair of wall panels 3 are hollowed out to form a water outlet 4, the photovoltaic panel 1 is arranged in the middle of the top frame 2, the top frame 2 is connected to the bottom bracket 6 in a swingable manner, and is supported by the bottom bracket 6; a cleaning device, which includes a first spray mechanism 18, a cleaning brush 19 and a driving mechanism, the cleaning brush 19 is arranged on one side of the first spray mechanism 18, the driving mechanism is connected to the first spray mechanism 18, drives the first spray mechanism 18 and the cleaning brush 19 moves along the surface of the photovoltaic panel 1. When no cleaning is performed, the first spray mechanism 18 and the cleaning brush 19 are arranged on one side of the top frame 2; a planting device, which includes a water reservoir 12, an annular water diversion trough 8, a planting trough 7 and an irrigation mechanism, wherein the water reservoir 12 is arranged below the ground, the annular water diversion trough 8 is arranged above the water reservoir 12, the annular water diversion trough 8 has an annular water inlet located at the top and an annular water outlet located at the bottom, the annular water inlet is formed on the ground and is aligned with the water flow outlets 4 of the four frame structures of the top frame 2, the annular water outlet is connected to the water reservoir 12, the planting trough 7 is arranged in the middle of the annular drinking trough, and the irrigation mechanism is connected to the water reservoir 12 to drive the water in the water reservoir 12 to the planting trough 7.

[0022] The photovoltaic device provided by the present invention sets the photovoltaic panel 1 in the middle of the top frame 2, so that the top frame 2 surrounds the photovoltaic panel 1, and the top frame 2 is surrounded by four frame structures, and each frame structure includes a pair of wall panels 3 to form a water outlet 4 therebetween. The top frame 2 is set on the top of the bottom bracket 6 and is supported by the bottom bracket 6. When the photovoltaic device is working normally, the top frame 2 can swing relative to the bottom bracket 6 under the drive of the motor to adjust the angle of the photovoltaic panel 1 relative to the ground, so as to convert solar energy with higher efficiency.

[0023] When the photovoltaic panel 1 needs to be cleaned, the cleaning device is started. At this time, the photovoltaic panel 1 is adjusted to a state parallel to the ground, and the driving mechanism drives the first spray mechanism 18 to move from one side of the top frame 2 to the other side of the top frame 2. At the same time, during the movement of the first spray mechanism 18, the first spray mechanism 18 sprays water to the photovoltaic panel 1, and the cleaning brush 19 cleans the photovoltaic panel 1 as the first spray mechanism 18 moves, and sweeps away the dust and sand on the surface of the photovoltaic panel 1. In the above cleaning process, as the cleaning brush 19 cleans, the cleaning waste water will overflow to the edges of the photovoltaic panel 1 and flow downward along the water outlet 4 formed by the four frame structures.

[0024] The planting device is arranged below the photovoltaic device. The annular water diversion trough 8 has an annular water inlet at the top and an annular water outlet at the bottom, wherein the annular water inlet forms the ground and is aligned with the water outlets 4 of the four frame structures, and the annular water outlet is connected to the reservoir 12 below the annular water diversion trough 8. Therefore, when the clean wastewater flows downward along the water outlets 4 of the four frame structures, it will just fall into the annular water inlet and be drained into the reservoir 12 along the annular water diversion trough 8, thereby realizing the automatic collection of clean wastewater. The planting device also provides a planting trough 7 and an irrigation mechanism, wherein the planting trough 7 is located in the middle of the annular water diversion trough 8, and sand-fixing plants are planted in the planting trough 7. The irrigation mechanism is connected to the reservoir 12, and the irrigation mechanism pumps water in the reservoir 12 into the planting trough 7 for plant growth. At the same time, the planting trough 7 is arranged in the middle of the annular water diversion trough 8, that is, the planting trough 7 is just below the photovoltaic panel 1. The photovoltaic panel 1 can block sunlight and serve the purpose of shading the plants to further improve the growth environment of the plants.

[0025] Based on the above process, the photovoltaic sand control system provided by the present invention can automatically collect water for cleaning the photovoltaic panel 1, and automatically irrigate the plants under the photovoltaic panel 1, thereby improving the utilization efficiency of water resources. At the same time, the photovoltaic panel 1 is used to block light, thereby achieving more efficient photovoltaic sand control.

[0026] In a preferred embodiment, in the photovoltaic sand control system, a filtering device is provided in the annular water diversion trough 8, and the filtering device includes a filter mesh 9, a filter layer 10 and a support structure 11. The filter mesh 9 is arranged at the annular water inlet position, and the filter layer 10 is arranged below the filter mesh 9. The support structure 11 is arranged below the filter layer 10 to support the filter layer 10.

[0027] Clean wastewater may contain impurities such as dust and sand. In order to prevent the impurities in the clean wastewater from clogging the water reservoir 12 or the annular water diversion trough 8, a filtering device is provided in the annular water diversion trough 8. Among them, the filter screen 9 can intercept impurities with larger particles such as sand, and the filter layer 10 can filter particles with smaller particle sizes such as dust. The support structure 11 can support the filter screen 9 and the filter layer 10, and the support structure 11 can be a structure such as a grid or a baffle provided on the wall of the annular water diversion trough 8.

[0028] In a preferred embodiment, in the photovoltaic sand control system, the filter screen 9 and the filter layer 10 are detachably arranged on the support structure 11 .

[0029] The filter screen 9 and the filter layer 10 are both placed on the support structure 11. The filter screen 9 and the filter layer 10 can be taken out from the annular water inlet 8 to achieve replacement. When the staff inspects the photovoltaic device, they can also check the filter device and replace the filter screen 9 or the filter layer 10 in time.

[0030] In a preferred embodiment, in the photovoltaic sand control system, the upper edges of the pair of wall panels 3 remain flush with the upper surface of the photovoltaic panel 1, and the pair of wall panels 3 extend downward to form a diversion channel 5, and the lower end outlet of the diversion channel 5 is the water flow outlet 4.

[0031] To ensure that clean wastewater can overflow from the surface of the photovoltaic panel 1 into the frame structure, the upper edge of a pair of wall panels 3 should be flush with the upper surface of the photovoltaic panel 1. A downwardly extending diversion channel 5 is formed between the pair of wall panels 3, and the clean wastewater can flow downward along the diversion channel 5 until it flows out from the water outlet 4. This design can reduce the loss of clean wastewater during the overflow process, so that it can be collected as much as possible in the annular water diversion trough 8 below. The height of the diversion channel 5 can extend to a certain distance below the photovoltaic panel 1, but care must be taken not to block too much light from the plants so as not to affect plant growth. The diversion channel 5 can also block part of the light to a certain extent to reduce the impact of excessive light on plants.

[0032] In a preferred embodiment, in the photovoltaic sand control system, a water level sensor is provided in the water reservoir 12, and a controller is connected to the water level sensor for receiving the water level in the water reservoir 12 detected by the water level sensor. When the water level in the water reservoir 12 drops to a set threshold, the controller sends an alarm to a remote management server, which is a server for managing the power generation status of the photovoltaic device.

[0033] In order to enable remote staff to timely understand the water level in the reservoir 12, a water level sensor is set in the reservoir 12. The controller monitors the water level detected by the water level sensor and sends an alarm signal to the remote management server when the water level is lower than the set threshold. The staff can replenish the water in the reservoir 12 in time according to the alarm signal. The management server can use the same server as the server used to manage the power generation status of the photovoltaic device. At the same time, the controller can also be connected to the first spray mechanism 18, the irrigation mechanism, the second spray mechanism 16, and the water pump and other equipment to control the operation of the above equipment, and send the working signals of these equipment to the management server for remote management by the staff.

[0034] In a preferred embodiment, in the photovoltaic sand control system, the irrigation mechanism includes a second spraying mechanism 16 and a water pump, the second spraying mechanism 16 is arranged in the planting trough 7, the water pump is connected to the water reservoir 12 through a water pumping pipe 14, and is connected to the second spraying mechanism 16 through a first water supply pipe 15, and is connected to the first spraying mechanism 18 through a second water supply pipe 17.

[0035] The irrigation mechanism includes a second spray mechanism 16 and a water pump. The second spray mechanism 16 is arranged in the planting trough 7, and can be realized by a drip irrigation system, for example. The water pump extracts the water stored in the water reservoir 12 through the water pumping pipe 14, and transports it to the second spray mechanism 16 through the first water supply pipe 15 and to the first spray mechanism 18 through the second water supply pipe 17. When water is supplied to the first spray mechanism 18, the photovoltaic panel 1 can be cleaned. In other words, the present invention can automatically collect the clean wastewater of the photovoltaic panel 1, filter and clean the clean wastewater, and then recycle the water for cleaning the photovoltaic panel 1 again. This further improves the utilization efficiency of water resources.
