Description

Technical Field

[0001] The invention belongs to the field of photovoltaic panel installation, in particular to an adjustable photovoltaic panel installation frame. Background Art

[0002] Photovoltaic power generation is one of the cleanest power generation methods of the future. It is of great significance for improving the environment, promoting energy upgrades and technological advancement, and promoting the healthy development of the photovoltaic industry. Photovoltaic panels rely on sunlight for power generation. The scale of power generation is positively correlated with the area of ​​the panels. Large-scale application of photovoltaic power generation depends on the large-scale installation of photovoltaic panels. Based on international experience, integrating photovoltaic power generation with buildings can solve the problem of limited installation area for photovoltaic power generation. This solution has also been applied in my country. The specific method is generally to install photovoltaic panels on the roofs of existing buildings. This installation method has, to a certain extent, solved the space problem of photovoltaic power generation.

[0003] When photovoltaic panels are installed on the roof of a building, due to being exposed all year round, a lot of dust will fall on their surface, blocking some light from reaching the cells and reducing the transmittance of the photovoltaic panels. Existing technology is not convenient for utilizing natural rainwater, and it is impossible to use natural rainwater to clean photovoltaic panels, resulting in a waste of natural resources. As a result, the photovoltaic panels can only be cleaned with tap water. However, the existing cleaning method is not convenient for adjusting the impact force of the water flow. When the water flow is used to flush the vicinity of the photovoltaic panel, the impact force of the water flow is too large. When it hits the dust on the photovoltaic panel, it will cause the dust to rub against the photovoltaic panel, thereby causing scratches. In addition, after cleaning the dust from the photovoltaic panel, the surface treatment of the photovoltaic panel is poor, resulting in water stains easily remaining on the photovoltaic panel. The water stains will form an uneven coverage on the surface of the photovoltaic panel, affecting the absorption of solar energy.

[0004] To this end, the present invention provides an adjustable photovoltaic panel mounting frame. Summary of the Invention

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] like Figures 1 to 13As shown, the present invention provides a technical solution, an adjustable photovoltaic panel mounting frame, including a water tank 1, a support frame 2 is fixedly connected to the top of the water tank 1, one end of the support frame 2 is rotatably connected to a mounting plate 3, a hydraulic cylinder 4 is fixedly installed on the top of the water tank 1, the output end of the hydraulic cylinder 4 is rotatably connected to a slider, the slider is slidably connected to the mounting plate 3, two photovoltaic panels 5 are symmetrically arranged on the top of the mounting plate 3, the top of the mounting plate 3 is fixedly connected to an annular side plate 6, one side of the annular side plate 6 is fixedly connected to a horizontal plate 7, the top of the horizontal plate 7 is fixedly connected to a support plate 8, the outer wall of the support plate 8 Two brackets 9 are symmetrically fixedly connected, and a rotating shaft 10 is rotatably connected between the two brackets 9. Several nozzles 11 are fixedly connected to the outer wall of the rotating shaft 10 at equal intervals. An adjustment component is provided on the top of the horizontal plate 7. A water pump 12 is fixedly installed on one side of the water tank 1. The input end of the water pump 12 is fixedly connected to a water inlet pipe 13. One end of the water inlet pipe 13 extends to the interior of the water tank 1. The output end of the water pump 12 is fixedly connected to several water outlet pipes 14. The water outlet pipe 14 is connected to the nozzle 11. A first water outlet 37 is opened inside the mounting plate 3, and a water circulation component is provided on the top of the water tank 1.

[0026] Through the above technical solution, the hydraulic cylinder 4 is started, and the output end of the hydraulic cylinder 4 drives the slider to move upward, so that the mounting plate 3 rotates along the support frame 2, thereby adjusting the inclination angle of the mounting plate 3, so that the photovoltaic panel 5 can face the sunlight and improve the absorption effect of solar energy. When it rains, the inclined mounting plate 3 cooperates with the annular side plate 6 to collect rainwater, and the rainwater slides down the inclined surface of the mounting plate 3 and is discharged from the mounting plate 3 through the first water outlet 37. The rainwater is filtered by the water circulation component to prevent the recycled rainwater from being mixed with dust and other debris. The filtered rainwater enters the water tank 1 and is collected. When the photovoltaic panel 5 is exposed for a long time and accumulates dust, Then, start the water pump 12 to pump out the rainwater collected in the water tank 1 along the water inlet pipe 13, and the pumped rainwater enters the nozzle 11 along the water outlet pipe 14, and is sprayed out through the nozzle 11 to clean the photovoltaic panel 5. In this way, the rainwater in nature is effectively utilized, which is more energy-saving and environmentally friendly. When flushing the position near the photovoltaic panel 5, the water pressure of the nozzle 11 is reduced through the provided adjustment component to avoid strong impact of the water flow on dust and the like, causing dust and the like to scratch the photovoltaic panel 5. When flushing the position far away from the photovoltaic panel 5, the water pressure of the nozzle 11 is increased through the provided adjustment component to avoid the inability to flush dust far away from the photovoltaic panel 5 due to insufficient water pressure.

[0027] Specifically, the adjusting component includes an electric telescopic rod 16, which is arranged at the top of the horizontal plate 7 and is rotatably connected to the horizontal plate 7. The outer wall of the rotating shaft 10 is fixedly connected to the positioning rod 15, and the output end of the electric telescopic rod 16 is rotatably connected to the positioning rod 15. Both sides of the nozzle 11 are fixedly connected to a fixed plate 17, and the inner walls of the two fixed plates 17 are slidably connected to a first sliding shaft 18. The tops of the two first sliding shafts 18 are fixedly connected to a top plate 21, and a baffle 22 is fixedly connected between the two top plates 21. A slot 23 is opened at the top of the nozzle 11, and the baffle 22 fits the inner wall of the slot 23. The bottoms of the two first sliding shafts 18 are fixedly connected to a first limit block 20, and the outer wall of the first sliding shaft 18 is sleeved with a first spring 19. The top of the first spring 19 is fixedly connected to the top plate 21, and the bottom of the first spring 19 is fixedly connected to the fixed plate 17. The outer wall of the support plate 8 and the limit plate 50 are fixedly connected above the baffle 22.

[0028] When the water level is too low, the water level will be increased, and the water pressure in the nozzle 11 will increase, so that the water flow can be sprayed farther and the impact force of the water flow will be increased. When the water level is too low, the water level will be increased, and the water pressure in the nozzle 11 will increase, so that the water flow can be sprayed farther and the impact force of the water flow will be increased. When the water level is too low, the water level will be increased, and the water pressure in the nozzle 11 will increase, so that the water flow can be sprayed farther and the impact force of the water flow will be increased. When the water level is too low, the water level will be increased, and the water pressure in the nozzle 11 will increase, so that the water flow can be sprayed farther and the impact force of the water flow will be increased. When the water level is too low, the water level will be increased, and the water pressure in the nozzle 11 will increase, so that the water flow can be sprayed farther and the impact force of the water flow will be increased. When the water level is too low, the water level will be increased, and the water pressure in the nozzle 11 will increase, so that the water flow can be sprayed farther and the impact force of the water flow will be reduced.

[0029] Specifically, a motor 24 is fixedly installed on one side of the annular side plate 6, and the output end of the motor 24 passes through the annular side plate 6 and is fixedly connected to a screw rod 25. The outer wall of the screw rod 25 is connected to a slide plate 26 through a screw nut pair. The slide plate 26 is slidably connected to the annular side plate 6, and the inner wall of the slide plate 26 is symmetrically slidably connected to two second sliding shafts 27. One end of the two second sliding shafts 27 is fixedly connected to a first extrusion plate 30, and the first extrusion plate 30 is symmetrically fixedly connected to two sponge pads 31 on one side near the slide plate 26. The other ends of the two second sliding shafts 27 are fixedly connected to a second limit block 28. The outer wall of the second sliding shaft 27 is sleeved with a second spring 29, one end of the second spring 29 is fixedly connected to the slide plate 26, and the other end of the second spring 29 is fixedly connected to the first extrusion plate 30. A through groove for cooperating with the screw rod 25 is provided inside the first extrusion plate 30, and a second water outlet 38 is provided on the top of the mounting plate 3 and on the side away from the first water outlet 37.

[0030] Through the above technical solution, after the photovoltaic panel 5 is flushed, the motor 24 is started to drive the screw 25 to rotate, so that the slide plate 26 moves to the side close to the first water outlet 37. When the slide plate 26 moves, it drives the first extrusion plate 30 and the sponge pad 31 to move. The accumulated water on the photovoltaic panel 5 is wiped by the moving sponge pad 31 to prevent excessive water accumulation on the photovoltaic panel 5. When the first extrusion plate 30 moves to a position close to the annular side plate 6, the first extrusion plate 30 cannot move due to the limit of the annular side plate 6. As the slide plate 26 continues to move, the sponge pad 31 between the slide plate 26 and the first extrusion plate 30 is squeezed to discharge the rainwater absorbed by the sponge pad 31. The rainwater squeezed out of the sponge pad 31 flows out along the first water outlet 37 and enters the water tank 1 again, thereby recycling and saving water resources.

[0031] Specifically, two push rods 33 are symmetrically slidably connected to the inner wall of the slide plate 26 , and one end of the two push rods 33 is fixedly connected to the second extrusion plate 32 , and the second extrusion plate 32 is attached to the outer wall of the sponge pad 31 .

[0032] Through the above technical solution, after squeezing out the rainwater in the sponge pad 31, the motor 24 controls the slide plate 26 to move back. At this time, the sponge pad 31 can wipe the photovoltaic panel 5 again to further absorb the rainwater on the photovoltaic panel 5. When the slide plate 26 moves to the other side of the annular side plate 6, under the extrusion of the annular side plate 6, the top rod 33 slides in the slide plate 26, pushing the second extrusion plate 32 to move toward the direction of the first extrusion plate 30, and squeezing out the rainwater absorbed by the sponge pad 31 again. At this time, the rainwater squeezed out of the sponge pad 31 falls from the second water outlet 38 and similarly enters the water tank 1 for recycling.

[0033] Specifically, a blocking plate 36 is fixedly connected to the top of the first extrusion plate 30 , and the blocking plate 36 is configured to be arc-shaped.

[0034] Through the above technical solution, when the nozzle 11 is used to flush the photovoltaic panel 5, the first extrusion plate 30 is controlled to move to the second water outlet 38. The baffle plate 36 is provided to block the rainwater sprayed from the nozzle 11 to prevent the rainwater from splashing to one side. Moreover, under the wrapping of the baffle plate 36 and the annular side plate 6, the sprayed rainwater can flow back downward along the inclined surface of the mounting plate 3, thereby performing secondary cleaning on the photovoltaic panel 5 and having a better effect on dust.

[0035] Specifically, two hot air blowers 34 are symmetrically fixedly connected to one side of the first extrusion plate 30 away from the slide plate 26 , and both hot air blowers 34 are installed at an angle.

[0036] Through the above technical solution, after the sponge pad 31 absorbs the rainwater remaining on the photovoltaic panel 5, the hot air blower 34 is started to blow hot air to the surface of the photovoltaic panel 5, thereby drying the photovoltaic panel 5 to avoid water stains on the photovoltaic panel 5. When fallen leaves are piled up on the photovoltaic panel 5, the hot air blown out by the hot air blower 34 can blow the fallen leaves away from the photovoltaic panel 5.

[0037] Specifically, a guide plate 35 is fixedly connected to the top of the hot air blower 34 , and the guide plate 35 is configured to be arc-shaped.

[0038] Through the above technical solution, the hot air blown out by the hot air blower 34 is wrapped by the arc-shaped guide plate 35 to prevent the hot air from hitting the photovoltaic panel 5 and then quickly drifting upward, thereby improving the drying effect of the hot air on the photovoltaic panel 5. Moreover, under the guiding effect of the concave surface of the guide plate 35, the overflowing hot air can flow along the surface of the photovoltaic panel 5, so that the drying effect of the hot air is better.

[0039] Specifically, the water circulation component includes two water inlets 44, both of which are opened at the top of the water tank 1 and are respectively located below the first water outlet 37 and the second water outlet 38. The top of the water tank 1 is symmetrically slidably connected with four third sliding shafts 40, and the tops of the four third sliding shafts 40 are fixedly connected with filter plates 43. The tops of the filter plates 43 are set as symmetrical inclined planes, and the tops of the filter plates 43 are provided with empty grooves. The bottoms of the four third sliding shafts 40 are fixedly connected with third limit blocks 42, and the outer wall of the third sliding shaft 40 is provided with a third spring 41. The top of the third spring 41 is fixedly connected to the filter plate 43, and the bottom of the third spring 41 is fixedly connected to the water tank 1.

[0040] Through the above technical solution, rainwater falling from the first water outlet 37 and the second water outlet 38 falls on the inclined surface of the filter plate 43, and is filtered by the filter plate 43, so that dust and other debris remain on the filter plate 43 and slide down along the inclined surface of the filter plate 43. The filtered rainwater passes through the filter plate 43 and falls, and passes through the water inlet 44 into the water tank 1 for storage.

[0041] Specifically, the outer wall of the output end of the hydraulic cylinder 4 is fixedly connected to a connecting shaft 46, and the bottom of the connecting shaft 46 is symmetrically fixedly connected to two fixed shafts 47. The inner wall of the fixed shaft 47 is equidistantly slidably connected to a number of protrusions 49, and the top and bottom of the protrusion 49 are both set as inclined surfaces. One end of the protrusion 49 is fixedly connected to a fourth spring 48, and the fourth spring 48 is fixedly connected to the fixed shaft 47. The elastic force of the fourth spring 48 is greater than the elastic force of the third spring 41.

[0042] When the hydraulic cylinder 4 controls the sliding block to move up and down, the angle of the photovoltaic panel 5 is adjusted. When the hydraulic cylinder 4 controls the photovoltaic panel 5 to rotate downward, the fixed shaft 47 is driven to move downward, causing the protrusion 49 to move downward. When the inclined surface of the protrusion 49 is pressed against the empty groove of the filter plate 43, it is stuck. As the fixed shaft 47 moves downward, the filter plate 43 is pushed downward, pressing the third spring 41. When the third spring 41 is compressed to the limit, the filter plate 43 is squeezed to make the protrusion 49 move toward the inside of the fixed shaft 47, pressing the fourth spring 48. When the protrusion 49 is separated from the filter plate 43, the filter plate 43 is driven to vibrate upward under the action of the third spring 41. Thus, the filter plate 43 is reciprocated through the provided several protrusions 49. When the photovoltaic panel 5 is controlled to rotate downward, the filter plate 43 is continuously vibrated, which is convenient for shaking off the dust and the like filtered on the filter plate 43, preventing the dust and the like from adhering to the filter plate 43 and affecting the filtering effect of rainwater.

[0043] Specifically, a guide assembly is provided at the bottom of the mounting plate 3 and below the first water outlet 37 and the second water outlet 38. The guide assembly includes two guide plates 39. The two guide plates 39 are symmetrically fixedly connected to the bottom of the mounting plate 3. The two guide plates 39 are both installed at an angle. A slide groove is provided at the top of the two guide plates 39. Two extension plates 45 are symmetrically fixedly connected to the top of the filter plate 43 and above the water inlet 44.

[0044] Through the above technical solution, the guide plate 39 is provided to guide the rainwater falling from the first water outlet 37 and the second water outlet 38, so that the rainwater can fall on the highest point of the filter plate 43, thereby extending the residence time of the rainwater on the filter plate 43 and preventing the rainwater from sliding directly from the inclined surface of the filter plate 43. The two extension plates 45 are provided to facilitate the wrapping of the rainwater falling on the filter plate 43 to prevent the rainwater from splashing everywhere.

[0045] When in use, the hydraulic cylinder 4 is started, and the output end of the hydraulic cylinder 4 drives the slider to move upward, so that the mounting plate 3 rotates along the support frame 2, thereby adjusting the inclination angle of the mounting plate 3, so that the photovoltaic panel 5 can face the sunlight and improve the absorption effect of solar energy. When it rains, the inclined mounting plate 3 cooperates with the annular side plate 6 to collect rainwater, and the rainwater slides down along the inclined surface of the mounting plate 3 and is discharged from the mounting plate 3 through the first water outlet 37 and the second water outlet 38. The rainwater falling from the first water outlet 37 and the second water outlet 38 falls on the inclined surface of the filter plate 43, and is filtered by the filter plate 43, so that dust and other debris remain on the filter plate 43 and slide down along the inclined surface of the filter plate 43. The filtered rainwater passes through the filter plate 43 and falls, and passes through the water inlet 4 4 enters the water tank 1 for storage, and the guide plate 39 is provided to guide the rainwater falling from the first water outlet 37 and the second water outlet 38 so that the rainwater can fall on the highest point of the filter plate 43, thereby extending the residence time of the rainwater on the filter plate 43 and preventing the rainwater from sliding directly from the inclined surface of the filter plate 43. The two extension plates 45 are provided to facilitate the wrapping of the rainwater falling on the filter plate 43 to prevent the rainwater from splashing everywhere. When the hydraulic cylinder 4 controls the photovoltaic panel 5 to rotate downward, it drives the fixed shaft 47 to move downward, causing the protrusion 49 to move downward. When the inclined surface of the protrusion 49 is pressed against the empty groove of the filter plate 43, it is stuck. As the fixed shaft 47 moves downward, the filter plate 43 is pushed downward, pressing the third spring 41. When the third spring 41 is compressed to the limit, the filter plate 43 is pressed downward. 43 is squeezed, so that the protrusion 49 moves toward the inside of the fixed shaft 47, compressing the fourth spring 48. When the protrusion 49 is separated from the filter plate 43, the filter plate 43 is driven to vibrate upward under the action of the third spring 41. Thus, the filter plate 43 is reciprocated, and the plurality of protrusions 49 are provided. When the photovoltaic panel 5 is controlled to rotate downward, the filter plate 43 is continuously vibrated, so that the dust and the like filtered on the filter plate 43 are shaken off, and the dust and the like are prevented from adhering to the filter plate 43 and affecting the filtering effect of rainwater. When the photovoltaic panel 5 is exposed for a long time and dust is accumulated, the water pump 12 is started to pump the rainwater collected in the water tank 1 out along the water inlet pipe 13. The pumped rainwater enters the nozzle 11 along the outlet pipe 14 and is sprayed out through the nozzle 11 to clean the photovoltaic panel 5, thereby effectively utilizing the rainwater in nature. It is more energy-saving and environmentally friendly. When washing a position far away from the photovoltaic panel 5, the electric telescopic rod 16 is used to control the positioning rod 15 to rotate upward, driving the nozzle 11 to rotate upward, and the top of the baffle 22 is pressed against the limit plate 50. Under the reverse push of the limit plate 50, the baffle 22 slides in the nozzle 11. At this time, the diameter of the nozzle 11 gradually decreases, so that the water pressure of the nozzle 11 is increased, so that the water flow can spray farther and increase the impact force of the water flow, avoiding the inability to wash dust far away from the photovoltaic panel 5 due to insufficient water pressure. When the baffle 22 slides in the nozzle 11, the first spring 19 is pressed. When washing a position near the photovoltaic panel 5, the electric telescopic rod 16 is used to control the positioning rod 15 to rotate downward, driving the nozzle 11 to rotate downward. Under the action of the first spring 19,The baffle 22 is driven to move back, so that the diameter of the nozzle 11 gradually becomes larger, the water pressure in the nozzle 11 is reduced, and then the impact force of the water flow is reduced, and the impact force of the nozzle 11 on the position near the photovoltaic panel 5 is reduced, so as to avoid the strong impact of the water flow on dust and the like, which causes the dust and the like to scratch the photovoltaic panel 5. After the photovoltaic panel 5 is flushed, the motor 24 is started to drive the screw rod 25 to rotate, so that the slide plate 26 moves to the side close to the first water outlet 37. When the slide plate 26 moves, it drives the first extrusion plate 30 and the sponge pad 31 to move. The water on the photovoltaic panel 5 is wiped by the moving sponge pad 31 to prevent excessive water accumulation on the photovoltaic panel 5. When the pressing plate 30 moves to a position close to the annular side plate 6, the first squeezing plate 30 cannot move under the limit of the annular side plate 6. As the slide plate 26 continues to move, the sponge pad 31 between the slide plate 26 and the first squeezing plate 30 is squeezed to discharge the rainwater absorbed by the sponge pad 31. The rainwater squeezed out of the sponge pad 31 flows out along the first water outlet 37 and enters the water tank 1 again, thereby recycling and saving water resources. After squeezing out the rainwater in the sponge pad 31, the motor 24 controls the slide plate 26 to move back. At this time, the sponge pad 31 can wipe the photovoltaic panel 5 again to further absorb the rainwater on the photovoltaic panel 5. When the slide plate 26 moves to When the annular side plate 6 is on the other side, the push rod 33 slides in the slide plate 26 under the extrusion of the annular side plate 6, pushing the second extrusion plate 32 to move in the direction of the first extrusion plate 30, and squeezing out the rainwater absorbed by the sponge pad 31 again. At this time, the rainwater squeezed out from the sponge pad 31 falls from the second water outlet 38 and enters the water tank 1 for recycling. When the nozzle 11 is used to flush the photovoltaic panel 5, the first extrusion plate 30 is controlled to move to the second water outlet 38. The baffle plate 36 is provided to block the rainwater sprayed from the nozzle 11 to prevent the rainwater from splashing to one side, and the rainwater sprayed is wrapped by the baffle plate 36 and the annular side plate 6. Water can flow back down along the slope of the mounting plate 3, performing a secondary cleaning of the photovoltaic panel 5 and achieving a better dust removal effect. After the sponge pad 31 has absorbed the remaining rainwater on the photovoltaic panel 5, the hot air blower 34 is activated to blow hot air onto the surface of the photovoltaic panel 5, thereby drying the photovoltaic panel 5 and preventing water stains on the photovoltaic panel 5. The hot air blown out by the hot air blower 34 is wrapped by the curved guide plate 35, preventing the hot air from hitting the photovoltaic panel 5 and then quickly drifting upward, thereby improving the drying effect of the hot air on the photovoltaic panel 5. The concave surface of the guide plate 35 guides the overflowing hot air to flow along the surface of the photovoltaic panel 5, achieving a better drying effect.
