Description

Technical Field

[0001] This invention relates to the field of photovoltaic technology, specifically to photovoltaic mounting brackets and installation methods on slopes. Background Technology

[0002] Photovoltaics refers to the technology of directly converting light energy into electrical energy, mainly through photovoltaic cells (solar cells). The basic principle of photovoltaic technology is to utilize the photovoltaic effect, that is, when photons shine on semiconductor materials (such as silicon), they will excite electrons, thereby generating an electric current.

[0003] When installing photovoltaic (PV) panels on a slope, workers need to move the PV panels one by one onto the PV bracket and adjust their positions before securing them to the bracket with screws. Since slope PV mounting brackets are fixed structures, moving the PV panels onto the bracket requires overcoming the height of the panels and makes angle adjustment difficult, resulting in time-consuming, labor-intensive, and inefficient installation. Therefore, we propose a slope PV mounting bracket and installation method to address these shortcomings of existing technology. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a photovoltaic mounting bracket and installation method for sloping surfaces, which has advantages such as overcoming installation height limitations and facilitating adjustment of the installation angle.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: a photovoltaic installation bracket on a slope, comprising two pairs of concrete columns, wherein a movable bracket slides inside the left concrete column, and a fixed bracket is installed at the top of the right concrete column.

[0008] The fixed bracket is equipped with a sliding connector, and a lifting mechanism is provided between the concrete columns on the left side. Both the sliding connector and the fixed bracket are equipped with rotating parts, and a pair of bracket crossbars are provided between the rotating parts. During operation, the lifting mechanism drives the movable bracket to move, which in turn rotates with the rotating parts and drives the sliding connector to move, changing the height and angle of the bracket crossbars.

[0009] The bracket has a fixed support vertical bar in the middle of the crossbar. Based on the fixed support vertical bar, there are at least two movable support vertical bars on both sides of the crossbar. The fixed support vertical bar and the movable support vertical bar are provided with adjustment and fixing parts and side clamping parts for fixing the installed photovoltaic panels on all four sides.

[0010] Furthermore, the sliding connector includes a guide rod and a movable seat, the guide rod being mounted on the top of the fixed bracket, and the movable seat sliding on the guide rod.

[0011] Furthermore, the lifting mechanism includes a sliding disc installed at the bottom of the movable support and a loading seat installed between the concrete columns on the left. A drive motor is installed on the surface of the loading seat, and a rotating shaft that rotates inside the loading seat is installed at the output end of the drive motor. A pair of guide wheels are installed on the outside of the loading seat, and a pair of winding discs are installed on the outside of the rotating shaft. A steel wire rope that passes around the guide wheels and connects to the sliding disc is wound on the outside of the winding discs.

[0012] Furthermore, a locking disc is installed at the top of the concrete column on the left, and the locking disc has at least four locking holes. The surface of the sliding disc is equipped with locking screws equal in number to the number of locking holes.

[0013] Furthermore, the rotating component includes a hinge seat installed between the movable seats and between the fixed brackets, and a rotating seat is rotatably mounted outside the hinge seat;

[0014] The crossbar of the support is connected between the rotating seats.

[0015] Furthermore, the adjusting fastener includes a directional sliding rod installed on the front and rear sides of the bottom end of the vertical rod of the fixed bracket, the movable support vertical rod is slidably sleeved on the outside of the directional sliding rod, and locking nuts are installed on the outside of both ends of the directional sliding rod;

[0016] The fixed support vertical rod and the movable support vertical rod are provided with placement grooves on the left and right sides of their upper surfaces. The photovoltaic panels are placed between two adjacent placement grooves. The surface of the support horizontal rod is provided with a sliding groove for the movable support vertical rod to slide.

[0017] Furthermore, the side clamping member includes mounting plates installed on the front and rear sides of the vertical rod of the fixed bracket. A bidirectional threaded rod is rotatably mounted on the mounting plate. The bidirectional threaded rod is provided with threaded grooves arranged in both directions. A threaded moving seat is threadedly connected in the threaded groove. An adjusting rod is mounted on the threaded moving seat. At least four clamping plates slide outside the adjusting rod. A slide block passing through the threaded moving seat is installed between the mounting plates. A locking groove is provided on the upper surface of the slide block. A locking screw located in the locking groove is threadedly connected to the threaded moving seat.

[0018] Furthermore, it also includes a water storage tank and at least five water pipes, which are respectively installed on the middle of the upper surface of the fixed support vertical rod and the movable support vertical rod. Multiple downwardly inclined nozzles are provided on the right side of the water pipes. The front end of the water pipes is connected to a flexible hose, and the other end of the flexible hoses is connected to a connecting pipe. A water pump is installed on the outside of the water storage tank, and a drain pipe is connected between the drain outlet of the water pump and the connecting pipe.

[0019] Furthermore, a water receiving seat is provided between the right sides of the guide rod, located below the rightmost movable support vertical rod. A clean water layer is provided inside the water receiving seat. A water outlet pipe located below the clean water layer is connected to the surface of the water receiving seat. The other end of the water outlet pipe is connected to a return water sedimentation seat. A timed electric valve is connected between the return water sedimentation seat and the water storage tank. A sedimentation storage cylinder is connected to the bottom end of the return water sedimentation seat. A sewage pipe is connected to the bottom end of the sedimentation storage cylinder. An automatic switch valve is connected to the outside of the sewage pipe.

[0020] The installation method for photovoltaic mounting brackets on slopes involves moving the movable bracket down to the bottom of the concrete column by driving the lifting mechanism during photovoltaic panel installation. The rotating component then moves the sliding connector, lowering the bracket's horizontal bar to the bottom and making it horizontal. This allows installers to overcome installation height limitations and place the photovoltaic panel between the fixed bracket vertical bar and the movable support vertical bar. After placement, the adjusting fixing component and side clamping component are used to clamp the photovoltaic panel on all four sides. Then, the lifting mechanism is activated again to move the movable bracket upwards, resulting in an inclined installation of the photovoltaic panel.

[0021] (III) Beneficial Effects

[0022] Compared with the prior art, the present invention provides a photovoltaic mounting bracket and installation method for sloping surfaces, which has the following beneficial effects:

[0023] 1. The photovoltaic mounting bracket and installation method on the slope involves driving a lifting mechanism to move the movable bracket down to the bottom of the concrete column. This, combined with the rotation of the rotating component, moves the sliding connector, causing the bracket's horizontal bar to move to the bottom and become horizontal. This facilitates installation by overcoming height limitations, improving the convenience and efficiency of the photovoltaic panel installation. The photovoltaic panel is placed between the fixed bracket vertical bar and the movable support vertical bar. After placement, the adjusting fixing component and side clamping component are used to clamp the photovoltaic panel on all four sides. Then, the lifting mechanism is activated again to move the movable bracket upwards, causing the installed photovoltaic panel to be tilted. This allows for quick adjustment of the photovoltaic panel's tilt angle according to installation needs.

[0024] 2. The photovoltaic mounting bracket and installation method on the slope involves using a water pump to draw water from the storage tank and spray it out through nozzles on the water pipe. This allows the sprayed water to clean the surface of the photovoltaic panels. The cleaned water flows along the slope of the photovoltaic panels into the water receiving base, where it is filtered through a clean water layer and then discharged into the return water sedimentation base. The sediment in the return water settles into the sedimentation storage cylinder. A timed electric valve controls the drainage time, ensuring that after sedimentation, the water is discharged back into the storage tank for reuse. After drainage is completed, the valve automatically opens to discharge the sediment, facilitating the reuse of the return water after further cleaning. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] like Figures 1 to 5As shown, the photovoltaic installation bracket on the slope includes two pairs of concrete columns 1. The concrete columns 1 are cylindrical columns made of reinforced concrete. The concrete columns 1 are poured into the ground through a casting hole and are arranged in a rectangular pattern to ensure that the upper surfaces of the concrete columns 1 are on the same horizontal plane. The left concrete column 1 has a reserved cavity, through which the movable bracket 3 can be moved up and down in a directional manner. The top center of the right concrete column 1 is fixed with a fastening screw and a sliding connector is provided at the upper end of the fixed bracket 2. A lifting mechanism is provided between the left concrete columns 1. Both the sliding connector and the fixed bracket 2 have rotating parts. A pair of bracket crossbars 8 are symmetrically distributed between the rotating parts. During operation, the lifting mechanism drives the movable bracket 3 to move, which in turn rotates the rotating parts and drives the sliding connector to move, changing the height and angle of the bracket crossbars 8.

[0033] Among them, a fixed support vertical bar 18 is welded between the middle of the support crossbar 8. Based on the fixed support crossbar 18 as the center, at least two movable support vertical bars 20 are provided on both sides of the support crossbar 8. Adjustable fixing parts and side clamping parts are provided between the fixed support vertical bar 18 and the movable support vertical bars 20 to fix the installed photovoltaic panel on all four sides.

[0034] like Figures 1 to 2 As shown, in this embodiment, the sliding connector includes a guide rod 4 and a movable seat 5. The guide rod 4 is welded to the top of the fixed bracket 2, and the movable seat 5 slides on the guide rod 4. A certain distance is reserved on the left side of the guide rod 4 for the movable seat 5 to slide. The lifting mechanism includes a sliding disc 11 welded to the center of the bottom of the movable bracket 3. The sliding disc 11 has the same diameter as the reserved cavity to ensure that the sliding disc 11 moves stably up and down in the concrete column 1 and avoids deflection during movement. It also includes a loading seat 9 that is fastened and fixed between the left concrete columns 1 by a collar and fastening screws. A drive motor 10 is installed and fixed on the front surface of the loading seat 9 by fastening screws. The output end of the drive motor 10 is installed and fixed to rotate circumferentially on the inner wall of the loading seat 9. The rotating shaft 12 has a pair of guide wheels 13 fixed on the upper surface of the loading seat 9. The guide wheels 13 are located above the two concrete columns 1 on the left. A pair of symmetrically distributed winding discs 14 are fixed on the outside of the rotating shaft 12. A steel wire rope 15 is wound around the outside of the winding disc 14, passing around the guide wheels 13 and connecting to the sliding disc 11. The steel wire rope 15 is perpendicular to the upper surface of the concrete column 1. The rotating component includes a hinge seat 6 installed and fixed between the movable seat 5 and the fixed bracket 2. A rotating seat 7 rotates around the outer circumference of the hinge seat 6. The bracket crossbar 8 is connected and fixed between the upper surfaces of the rotating seat 7. The upper surface of the bracket crossbar 8 is provided with a sliding groove 19 for the movable support vertical bar 20 to slide.

[0035] The working principle of this embodiment is as follows: When installing photovoltaic panels, the drive motor 10 is started to drive the winding disc 14 on the rotating shaft 12 to rotate in both directions, which winds and unwinds the steel wire rope 15. When photovoltaic panel installation is required, the drive causes the steel wire rope 15 to be unwinded. Under the directional guiding action of the guide wheel 13, the traction sliding disc 11 and the moving bracket 3 move linearly downward in the concrete column 1. During the downward movement of the moving bracket 3, the left hinge seat 6 moves down synchronously, causing the rotating seat 7 to rotate on the hinge seat 6. During the angle change of the movement, the right hinge seat 6 moves on the guide rod 4 through the moving seat 5, so that the guide rod is close to the right concrete column 1. This makes the bracket crossbar 8 on the rotating seat 7 gradually level with the concrete column 1, thus ensuring that the bracket crossbar 8 changes from an inclined plane to a horizontal plane, reducing the installation height. This makes it easier to install photovoltaic panels while reducing the height and maintaining a horizontal state, improving the convenience and efficiency of photovoltaic panel installation.

[0036] In addition, based on the above principle, after the photovoltaic panel is installed, the drive motor 10 is started to wind up the steel wire rope 15, thereby pulling the moving bracket 3 upward. During the upward movement, the surface of the bracket crossbar 8 is tilted downward from left to right, which makes it convenient to adjust the tilt angle of the photovoltaic panel after installation according to the upward movement distance of the moving bracket 3, thus improving the convenience of installation and adjustment angle.

[0037] like Figure 2 As shown, in this embodiment, a locking disc 16 with the same center is installed and fixed at the top of the left concrete column 1 by fastening screws. The locking disc 16 has at least four locking holes 17 distributed in a ring at equal distances. The upper surface of the sliding disc 11 is welded with locking screws 46 that correspond one-to-one with the number of locking holes 17. The setting distance of the locking screws 46 can be set according to the angle of the photovoltaic panel adjustment.

[0038] The working principle of this embodiment is as follows: after the photovoltaic panel is installed, when the sliding plate 11 moves upward, the locking screw 46 passes through the locking hole 17. As the sliding plate 11 moves upward, after adjusting to the inclined angle of the photovoltaic panel installation, the locking screw 46 is locked and fixed to the locking plate 16 by tightening the fastening nut on the outside of the locking screw 46, thus realizing the installation and fixing after the adjustment of the movable installation.

[0039] like Figure 1 and Figure 3As shown, in this embodiment, the adjusting fixing component includes directional sliding rods 22 symmetrically distributed on the front and rear sides of the bottom end of the fixed support vertical rod 18. The directional sliding rods 22 are located outside the support horizontal rod 8. The movable support vertical rod 20 is slidably sleeved on the outside of the directional sliding rods 22. Locking nuts 23 are threaded to both ends of the directional sliding rods 22. Placement slots 21 are provided on the left and right sides of the upper surface of the fixed support vertical rod 18 and the movable support vertical rod 20. The photovoltaic panel is placed between two adjacent placement slots 21. The upper surface of the support horizontal rod 8 is provided with a sliding groove 19 for the movable support vertical rod 20 to slide.

[0040] The working principle of this embodiment is as follows: when the support crossbar 8 is adjusted and moved down to the bottom and is in a horizontal state with the upper surface of the concrete column 1, the photovoltaic panel is placed between the adjacent placement slots 21 formed by the fixed support vertical bar 18 and the movable support vertical bar 20. After the photovoltaic panel is laid flat in the plane formed by the fixed support vertical bar 18 and the movable support vertical bar 20, the locking nut 23 is screwed in to clamp and fix the photovoltaic panel on the left and right sides after installation by the combination of the fixed support vertical bar 18 and the movable support vertical bar 20.

[0041] like Figure 1 and Figure 5 As shown, in this embodiment, the side clamping component includes mounting plates 24 on the front and rear sides of the fixed bracket vertical rod 18. A bidirectional threaded rod 25 rotates circumferentially between the mounting plates 24. The outer side of the bidirectional threaded rod 25 has threaded grooves arranged in the forward and reverse directions respectively on the front and rear sides of the middle. Threaded moving seats 26 are threadedly connected in the threaded grooves and are symmetrically distributed in the front and rear of the center. An adjusting rod 27 is fixedly fixed through the threaded moving seat 26 in a horizontal direction. At least four clamping plates 28 slide outside the adjusting rod 27. A slide seat 29 passing through the threaded moving seat 26 is installed and fixed between the mounting plates 24. A locking groove 30 is opened on the upper surface of the slide seat 29. A locking screw 31 located in the locking groove 30 is threadedly connected to the threaded moving seat 26. The clamping plates 28 slide horizontally in a straight line on the adjusting rod 27 without deflection.

[0042] The working principle of this embodiment is as follows: after the front and rear sides of the photovoltaic panel are clamped and fixed, the clamping plate 28 is adjusted to move on the adjusting rod 27 to ensure that each clamping plate 28 is located on the front and rear sides of each group of vertically spliced ​​photovoltaic panels. Thus, by rotating the bidirectional threaded rod 25 on the mounting plate 24, the threaded connection between the positive and negative threaded grooves and the threaded moving seat 26, as well as the linear limiting movement of the sliding seat 29 on the threaded moving seat 26, ensures that the clamping plates 28 on the front and rear sides move towards each other when the bidirectional threaded rod 25 rotates. This allows the clamping plates 28 to move and clamp and limit the photovoltaic panels after assembly. After clamping, the locking screw 31 can be locked and fixed in the locking groove 30 by rotating the fastening screw 31, thereby achieving the positioning and fixing of the clamping plate 28 after clamping, and thus achieving four-sided fixing of the photovoltaic panels after installation and assembly.

[0043] like Figure 1 and Figure 4 As shown, in this embodiment, the application also includes a water storage tank 32 and at least five water pipes 36. The water storage tank 32 is placed on the ground. The water pipes 36 are respectively installed and fixed to the middle of the upper surface of the fixed support vertical rod 18 and the movable support vertical rod 20, and are the same length as the fixed support vertical rod 18 and the movable support vertical rod 20. The right side of the water pipe 36 is connected to a plurality of downwardly inclined nozzles 37 evenly distributed. The front end of the water pipe 36 is connected to a flexible hose 47, and the other ends of the flexible hoses 47 are connected to a connecting pipe 35. The water pump 33 is fixed to the outside of the water storage tank 32 by fastening screws. The inlet of the water pump 33 is connected to the water storage tank 32 through an inlet pipe. The outlet of the water pump 33 is connected to the connecting pipe 35 through a drain pipe 34. The upper surface of the water storage tank 32 is provided with an opening, and a switch cover is provided at the opening. Cleaning fluid can be added to the water storage tank 32 by opening the switch cover.

[0044] The working principle of this embodiment is as follows: In order to ensure the cleanliness of the photovoltaic panel surface and improve the light conversion effect, the cleaning liquid stored in the water tank 32 is extracted by starting the water pump 33. By utilizing the interconnection between the water pump 33, the water tank 32, the drain pipe 34, the connecting pipe 35, the hose 47, the water pipe 36 and the nozzle 37, it is ensured that when the surface of the photovoltaic panel is tilted downward from left to right after installation, the nozzle 37 sprays the cleaning liquid to clean the dust on the surface of the photovoltaic panel, thereby ensuring the cleanliness of the photovoltaic panel's light-receiving surface and improving the light-receiving effect.

[0045] like Figure 1 and Figure 4As shown, in this embodiment, a water receiving seat 38 is installed and fixed between the right sides of the guide rod 4, located below the rightmost movable support vertical rod 20. The water receiving seat 38 is filled with a clean water layer 39, which is a filter screen made of activated carbon or other materials, and can be set according to the usage needs. The front surface of the water receiving seat 38 is connected to a water outlet pipe 40 located below the clean water layer 39. The other end of the water outlet pipe 40 is connected to a return water sedimentation seat 41. The upper surface of the return water sedimentation seat 41 is lower than the water outlet pipe 40, and the lower surface of the return water sedimentation seat 41 is flush with the upper surface of the water storage tank 32. A timed switch electric valve 42 is connected between the lower right surface of the return water sedimentation seat 41 and the upper left surface of the water storage tank 32. The bottom end of the return water sedimentation seat 41 is connected to a sedimentation storage cylinder 43, and the bottom end of the sedimentation storage cylinder 43 is connected to a drain pipe 44. An automatic switch valve 45 is connected to the outside of the drain pipe 44.

[0046] The working principle of this embodiment is as follows: when the surface of the photovoltaic panel is cleaned, the waste liquid after cleaning flows along the inclined surface of the photovoltaic panel into the water receiving base 38, and the impurities in the wastewater are filtered through the clean water layer 39. The filtered liquid is discharged into the return water sedimentation base 41 through the water outlet pipe 40 for sedimentation treatment. The sediment is stored in the sedimentation storage cylinder 43. After the sedimentation is completed, the timed switch electric valve 42 is opened according to the timed setting to discharge the upper clear liquid in the return water sedimentation base 41 into the water storage tank 32 for reuse. After the upper clear liquid is discharged, the automatic switch valve 45 is opened to discharge the sediment in the sedimentation storage cylinder 43. After discharge, the automatic switch valve 45 is closed to facilitate the return water sedimentation treatment after the next cleaning.

[0047] It should be added that the device of this application is equipped with a controller connected to the electrical equipment of this application for system control of the electrical equipment, and the time for switching the electric valve 42 on and off can be set according to the actual sedimentation time.

[0048] The installation method of the photovoltaic mounting bracket on the slope is as follows: When installing the photovoltaic panel, the moving bracket 3 is moved down to the bottom of the concrete column 1 by driving the lifting mechanism. The rotating part rotates and drives the sliding connecting part to move, so that the bracket crossbar 8 moves down to the bottom and makes the bracket crossbar 8 horizontal, so that the installer can overcome the installation height and place the photovoltaic panel between the fixed bracket vertical bar 18 and the moving support vertical bar 20. After the placement is completed, the adjusting fixing part and the side clamping part are adjusted to clamp the placed photovoltaic panel on all four sides. Then, the lifting mechanism is started again to move the moving bracket 3 up, so that the installed photovoltaic panel is set at an inclination.

[0049] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
