The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0025] like Figures 1 to 6 As shown, the present application provides a photovoltaic power station water treatment filtration and anti-clogging device, which is arranged below a photovoltaic panel 1, and a water guide trough 2 is arranged on the photovoltaic panel 1, comprising: a filter box 3, a cleaning mechanism and a driving mechanism, the filter box 3 is arranged below the water outlet of the water guide trough 2, the upper surface of the filter box 3 is inclined downward along the direction of the water flow and is provided with a plurality of water inlet gate ports 4, the water inlet gate ports 4 are used to filter sand and gravel; the cleaning mechanism comprises a plurality of first top plates 5, the first top plates 5 are arranged below the water inlet gate ports 4 and are slidably connected to the inner wall of the filter box 3, the first top plates 5 are perpendicular to the upper surface of the filter box 3 and correspond to the water inlet gate ports 4, the first top plates 5 move up and down along the water inlet gate ports 4; the driving mechanism is cooperatively connected to the bottom of the cleaning mechanism, and is used to drive the cleaning mechanism to move up and down.

[0026] Specifically, the photovoltaic panel 1 is arranged to be tilted downward, and a support frame is arranged below the photovoltaic panel 1, and the support frame can support and fix the stability of the photovoltaic panel 1. Water retaining plates are arranged on both sides of the photovoltaic panel 1 to prevent water from flowing out from the sides. A water guide trough 2 is arranged on the bottom edge of the photovoltaic panel 1 to collect water and flow out. A filter box 3 is arranged below the water outlet of the water guide trough 2, and the filter box 3 is fixed on the support frame. The upper surface of the filter box 3 is arranged to be tilted downward, and a plurality of water inlet gates 4 are arranged thereon. The water inlet gate 4 is a horizontal strip-shaped opening (perpendicular to the direction of water flow), which is used to prevent sand and gravel from entering the filter box 3. When cleaning the photovoltaic panel 1, the sand and gravel will be blocked by the water inlet gate 4, and the water will flow into the filter box 3 for storage and can be recycled. The cleaning mechanism is a first top plate 5 having the same number as the water inlet gate openings 4. The first top plate 5 is perpendicular to the upper surface of the filter box 3. Support plates are arranged on opposite sides of the inner wall of the filter box 3 (perpendicular to the water flow direction), and slide grooves (not shown in the figure) corresponding to the two side edges of the first top plate 5 are arranged above the support plates. The lower end of the first top plate 5 is supported on the support plate, and the two side edges are slidably connected in the slide grooves.

[0027] During the flushing process of the photovoltaic panel 1, some sand and gravel are stuck in the water inlet gate 4, and the driving mechanism is turned on, driving the first top plate 5 connected to the driving mechanism to slide in an inclined upward direction and extend into the water inlet gate 4, and the upper end of the first top plate 5 is flush with the upper end of the water inlet gate 4, so that a smooth plane is formed on the top of the filter box 3, and the sand and gravel stuck in the water inlet gate 4 rolls downward and slides out of the top of the filter box 3 by its own weight and the impact force of rainwater. After the upper end of the first top plate 5 is flush with the upper end of the water inlet gate 4, it immediately slides tilted downward and returns to the position before the driving mechanism is turned on, and then is driven by the driving mechanism to slide tilted upward again. The first top plate 5 is driven by the driving mechanism to continue to tilt upward and tilt downward, solving the problem of some sand and gravel being stuck in the water inlet gate 4.

[0028] The above technical solution adopted by the photovoltaic power station water treatment filtration and anti-clogging device provided in this application can achieve the following beneficial effects:

[0029] (1) The present application filters rainwater by providing a filter box 3 and a water inlet gate 4 on the upper surface of the filter box 3, so that sand and gravel are filtered through the water inlet gate 4, and rainwater enters the filter box 3 through the water inlet gate 4 for collection;

[0030] (2) In this process, part of the gravel in the rainwater is washed out by the water through the inclined surface, and part of it is stuck in the water inlet gate 4. By providing the first top plate 5 and the driving mechanism, the driving mechanism drives the first top plate 5 to move upward, and the gravel stuck in the water inlet gate 4 is pushed out. Through the continuous impact of water, the gravel is washed out from the top of the filter box 3. The problem that there is a lot of gravel in the suburbs, and the gravel is easy to block the filter port and affect the water source filtration is solved.

[0031] In a preferred embodiment, the cleaning mechanism includes a first top rod 6 , which is slidably connected to one side of the interior of the filter box 3 , and one end of the first top plate 5 is connected to the first top rod 6 .

[0032] Specifically, the first top plate 5 is welded to one side of the first top rod 6. Two L-shaped grooves are arranged on the side wall of the filter box 3, and the arrangement direction of the L-shaped grooves is perpendicular to the upper surface of the filter box 3. The two ends of the first top rod 6 are placed at the inner bottom of the L-shaped grooves. The bottom of the L-shaped grooves is used to support the first top rod 6. When the first top rod 6 is working, it moves stably along the vertical part of the L-shaped groove under the drive mechanism. Based on this technical solution, the first top rod 6 is driven by the drive mechanism to move, and the first top rod 6 can drive several first top plates 5 to move simultaneously during the movement, which simplifies the structure and reduces the cost.

[0033] Based on the above scheme, the cleaning mechanism also includes a second top rod 8 and a second top plate 7, the second top rod 8 is slidably connected to the inside of the filter box 3, and one end of the second top plate 7 is connected to the second top rod 8. The second top rod 8 and the second top plate 7 are arranged in the same manner as the first top rod 6 and the second top plate 7. The second top rod 8 is connected to the driving mechanism in cooperation with the driving mechanism. When the first top rod 6 slides upward, the second top rod 8 slides downward, so that the water inlet gate 4 is partially blocked by the first top plate 5 and partially open. On the contrary, when the first top rod 6 slides downward, the second top rod 8 slides upward, so that the water inlet gate 4 at the top of the filter box 3 can continue to filter and collect. When cleaning sand and gravel, the first top rod 6 and the second top rod 8 work alternately, and more water can be collected while cleaning sand and gravel.

[0034] To further optimize the above technical solution, a plurality of the first top plates 5 and a plurality of the second top plates 7 are arranged at intervals. Specifically, a second top plate 7 is arranged between two adjacent first top plates 5, and the number of the first top plates 5 is the same as the number of the second top plates 7. During operation, the first top rod 6 drives the first top plate 5 to move upward, and the first top plate 5 enters the water inlet gate 4. The upper plane of the first top plate 5 is flush with the water inlet gate 4. The sand and gravel roll to the next water inlet gate 4 or directly slide out of the filter box 3. Then the first top rod 6 drives the first top plate 5 to descend, and the second top rod 8 starts to drive the second top plate 7 to move upward and enter the water inlet gate 4. This embodiment is the most preferred one. The alternating and repeated work based on this embodiment allows the entire process to proceed smoothly and can reduce the waste of water resources.

[0035] In a preferred embodiment, the driving mechanism includes a rotating shaft 11, a motor 12 and a first cam 9. The rotating shaft 11 passes through the opposite sides of the filter box 3. The motor 12 is arranged on one side of the outer wall of the filter box 3 and is fixedly connected to one end of the rotating shaft 11. The first cam 9 is fixedly connected to the rotating shaft 11 and is arranged in cooperation with the first push rod 6. Specifically, the rotating shaft 11 crosses the opposite sides of the filter box 3, and the axis of the rotating shaft 11 is perpendicular to the direction of the water flow. The motor 12 is arranged on the outer wall of the filter box 3, and a support plate can be arranged at the lower end of the motor 12 to support the motor 12. The output end of the motor 12 is fixedly connected to one end of the rotating shaft 11, and the contact part of the rotating shaft 11 and the filter box 3 are both connected by bearings. The first cam 9 is arranged on the rotating shaft 11 and close to the first push rod 6. The first cam 9 is clamped on the rotating shaft 11. When the rotating shaft 11 rotates, the first cam 9 rotates coaxially with the rotating shaft 11. The first cam 9 can be set to one or more. For example, when there is one first cam 9, the first cam 9 can be set at the center of the first push rod 6, and the first cam 9 can be driven by the motor 12 through the rotating shaft 11; when there are two first cams 9, the first cams 9 can be respectively set at the two ends of the first push rod 6, and each cam is driven by a motor 12 and a rotating shaft 11, so that the first push rod 6 can be balanced during the rising process. In this application, in order to reduce costs, the first cam 9 can be set to one. Through the setting of this technical solution, the first top plate 5 can move up and down, thereby cleaning sand and gravel.

[0036] In order to ensure that the second push rod 8 can move up and down, the driving mechanism also includes a second cam 10, which is coaxial with the first cam 9 and is arranged in cooperation with the second push rod 8. Specifically, the structural design of the second cam 10 is consistent with the first cam 9. When the first cam 9 and the second cam 10 are working, when the first push rod 6 makes a push stroke movement, the second push rod 8 makes a return stroke movement; when the first push rod 6 makes a return stroke movement, the second push rod 8 makes a push stroke movement. Through this design, the first top plate 5 and the second top plate 7 move up and down alternately.

[0037] In order to ensure that the first push rod 6 and the first top plate 5 are smoothly and stably reset, a first spring 13 is provided at the upper end of the first push rod 6, and the other end of the first spring 13 is connected to the top of the filter box 3. Specifically, one end of the first spring 13 is fixed to the upper end surface of the first push rod 6, and the other end is fixed to the inner top of the filter box 3. Two first springs 13 are provided, which are respectively provided at the two ends of the first push rod 6. By providing the first spring 13, the first push rod 6 and the first top plate 5 can be smoothly returned to their original positions.

[0038] In order to ensure that the second top rod 8 and the second top plate 7 are smoothly and stably reset, a second spring 14 is provided at the upper end of the second top rod 8, and the other end of the second spring 14 is connected to the top of the filter box 3. Specifically, one end of the second spring 14 is fixed to the upper end surface of the second top rod 8, and the other end is fixed to the inner top of the filter box 3. Two second springs 14 are provided, which are respectively provided at the two ends of the second top rod 8. By providing the second spring 14, the second top rod 8 and the second top plate 7 can be smoothly returned to their original positions.

[0039] The water storage capacity in the filter box 3 is limited. When it rains, in order to reserve enough water for the subsequent cleaning of the photovoltaic panel 1, the photovoltaic power station water treatment filtration and anti-clogging device also includes a water tank 15. The water tank 15 is arranged below the photovoltaic panel 1, and the water inlet of the water tank 15 is connected to the water outlet of the filter box 3. Specifically, the water tank 15 is arranged on the ground. In order to reduce costs, the water tank 15 can be a brick-concrete structure, and the support frame of the photovoltaic panel 1 is fixed to the upper end of the water tank 15. Based on this solution, the bottom end of the filter box 3 is set to a downward inclined surface to prevent water from accumulating in the filter box 3. The water outlet of the filter box 3 extends to communicate with the water tank 15. By setting the water tank 15, the problem of limited water storage in the filter box 3 is solved.

[0040] Here’s how this application works:

[0041] Rainwater or cleaning water is collected in the water channel 2 through the photovoltaic panel 1, and the water carries sand and gravel to the water inlet gate 4, where the sand and gravel are blocked, and the water flows into the filter box 3 through the water inlet gate 4. The motor 12 is started, and the motor 12 drives the first cam 9 and the second cam 10 to rotate through the rotating shaft 11. The first cam 9 pushes the first push rod 6 to move (assuming that the first push rod 6 is pushed first), and the first push rod 6 drives the first top plate 5 to move upward, and the first top plate 5 enters the water inlet gate 4 at intervals. When the upper plane of the first top plate 5 is flush with the water inlet gate 4, The gravel rolls to the next water inlet gate 4. At this time, the first cam 9 separates from the first push rod 6, and the first push rod 6 returns to its original position under the action of the first spring 13; the second cam 10 pushes the second push rod 8 to move, and the second push rod 8 drives the second top plate 7 to move upward, and the second top plate 7 enters the water inlet gate 4 at intervals. When the upper plane of the second top plate 7 is flush with the water inlet gate 4, the gravel rolls to the remaining water inlet gate 4. At this time, the second cam 10 separates from the second push rod 8, and the second push rod 8 returns to its original position under the action of the second spring 14. The first cam 9 and the second cam 10 continuously rotate, driving the first push rod 6 and the second push rod 8 to move up and down alternately, thereby driving the first top plate 5 and the second top plate 7 to move up and down, and the gravel can be cleaned out of the water inlet gate 4 in sequence.

[0042] The above-described embodiments only express the way of equipment layout of the present application, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent application; it should be pointed out that for ordinary technicians in this field, several adjustments and improvements can be made without departing from the concept of the present application, which all belong to the scope of protection of the present application; therefore, the scope of protection of the patent of this application should be based on the attached claims.
