Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic accessory technology, and specifically relates to an adjustable side pressure device for photovoltaic modules. Background Technology

[0002] A photovoltaic (PV) module is a power generation device that produces direct current (DC) when exposed to sunlight. It consists of thin, solid-state photovoltaic cells made almost entirely of semiconductor materials, such as silicon. To mount the PV module onto a track, a lateral pressure device is used to press and limit the position of the PV panels.

[0003] Currently, patent CN216564995U discloses a photovoltaic adjustable side-pressure module, comprising: a side-pressure plate, a track mounting component, a pad, and a fixing component. The side-pressure plate has an arc-shaped recess, a pressing part located on one side of the arc-shaped recess, an abutting part located on the other side of the arc-shaped recess, and a clearance hole located within the arc-shaped recess. The pad is assembled within the arc-shaped recess and has an arc-shaped bottom surface that mates with the arc-shaped recess and a connecting hole corresponding to the clearance hole. The fixing component passes sequentially through the connecting hole of the pad and the clearance hole of the arc-shaped recess and is fixedly connected to the track mounting component; the fixing component and the clearance hole are in clearance fit. This photovoltaic adjustable side-pressure module can be adjusted within a certain range according to the actual height to press the solar panel.

[0004] In summary, while the aforementioned existing technologies satisfy the requirements for lateral pressure on photovoltaic panels and can accommodate adjustments to photovoltaic panels of a certain size, the lateral pressure components used to apply pressure to the photovoltaic panels during adjustment need to swing. After swinging, the contact area between the lateral pressure component and the photovoltaic panel decreases, thus reducing the stability of lateral pressure on the photovoltaic panels after adjustment. Secondly, the existing technologies apply lateral pressure to the top of the photovoltaic panel, but lack a corresponding limiting structure for the bottom. The photovoltaic module is directly laterally pressed and limited on the track, which is not conducive to adjusting the position of the photovoltaic module. If adjustment is required after installation, the fixing bolts need to be removed and the photovoltaic module lifted. Loosening the fixing bolts to adjust the photovoltaic module directly will cause friction between the photovoltaic module and the track. Summary of the Invention

[0005] The purpose of this invention is to provide an adjustable side pressure device for photovoltaic modules, which has the advantages of being adaptable to and having good stability of side pressure and convenient position adjustment. It solves the problems of decreased side pressure stability and inconvenience of position adjustment after the side pressure device of the photovoltaic module is adjusted according to the thickness of the photovoltaic panel.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an adjustable side pressure device for photovoltaic modules, including a connector, an upper pressure plate bolted to one side of the connector, a lower clamping plate provided inside the connector, an adjusting bolt threaded inside the lower clamping plate, a track mounting component provided at the bottom of the connector, a bearing embedded in the top of the track mounting component, a locking rod rotatably sleeved inside the bearing, a locking groove for engaging with the locking rod at the bottom end of the adjusting bolt, and a fixing component bolted to one side of the track mounting component and sleeved with the adjusting bolt.

[0007] The above technical solution allows for simultaneous fixation of the photovoltaic panel by setting an upper pressure plate and a lower clamping plate. After fixing the photovoltaic module during pressure testing, its position can be easily adjusted. By setting an adjusting bolt, a lower clamping plate, and an upper pressure plate, the photovoltaic panel can be adjusted up and down in a sliding manner without reducing the contact area, depending on the thickness of the photovoltaic panel.

[0008] The present invention is further configured such that a limiting member is bolted to the front of the track mounting component, and a limiting bolt is connected to the internal thread of the limiting member.

[0009] The above technical solution allows for the setting of limiting components and limiting bolts to limit the movement of the track-mounted components, thereby limiting the movement of the photovoltaic modules and the track.

[0010] The present invention is further provided that the bottom of the upper pressure plate and the top of the lower abutment plate are both provided with toothed grooves.

[0011] The above technical solution, with its toothed grooves, increases the friction between the upper pressure plate and the adjusting bolts and the photovoltaic panel.

[0012] The present invention is further configured such that a guide groove is provided on one side of the connector, and the interior of the guide groove is slidably connected to the surface of the lower abutment plate.

[0013] The above technical solution employs a guide groove design to facilitate the up-and-down sliding of the lower abutment plate.

[0014] The present invention is further configured such that a guide rod is slidably connected inside the lower abutment plate, and the top and bottom ends of the guide rod are bolted to the connector.

[0015] The above technical solution, with its internal sliding connection between the guide rod and the lower clamping plate, ensures that the lower clamping plate will not rotate together with the adjusting bolt.

[0016] The present invention is further configured such that a gasket is provided on the top of the fixing member, and the interior of the gasket is fitted onto the surface of the adjusting bolt.

[0017] The above technical solution uses shims to prevent direct contact between the adjusting bolts and the fasteners, thus reducing the wear rate of the fasteners.

[0018] In summary, this utility model has the following beneficial effects:

[0019] 1. By setting an upper pressure plate and a lower clamping plate, the upper pressure plate and the lower clamping plate are fixed to the top and bottom of the photovoltaic panel respectively under the adjustment of the adjusting bolts. After the track mounting parts and the track are installed, the photovoltaic module can be adjusted without disassembling the adjusting bolts, and there is no need to carry it. There will be no friction between the photovoltaic panel and the track.

[0020] The position of the lower clamping plate can be adjusted by setting the adjusting bolt. The distance between the lower clamping plate and the upper pressure plate can be adjusted according to the different thicknesses of the photovoltaic panel. After adjustment, the contact area between the upper pressure plate, the connector, the lower clamping plate and the photovoltaic panel will not decrease, and the stability will not change after adjustment.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings. Example

[0028] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5An adjustable side pressure device for photovoltaic modules includes a connector 1. An upper pressure plate 2 is bolted to one side of the connector 1. A lower abutment plate 3 is provided inside the connector 1. Toothed grooves are provided at the bottom of the upper pressure plate 2 and the top of the lower abutment plate 3 to increase the friction between the upper pressure plate 2, adjusting bolt 4, and the photovoltaic panel. A guide groove 12 is provided on one side of the connector 1, and the interior of the guide groove 12 is slidably connected to the surface of the lower abutment plate 3. The guide groove 12 facilitates the up-and-down sliding of the lower abutment plate 3. A guide rod 13 is slidably connected inside the lower abutment plate 3. The top and bottom ends of component 3 are bolted to connector 1. The guide rod 13 and the lower abutment plate 3 are internally slidably connected, ensuring that the lower abutment plate 3 will not rotate with the adjusting bolt 4. The lower abutment plate 3 is internally threaded with the adjusting bolt 4. The bottom of connector 1 is provided with a track mounting component 5. The front of the track mounting component 5 is bolted with a limit component 10. The internal thread of the limit component 10 is connected with a limit bolt 11. The limit component 10 and the limit bolt 11 can limit the track mounting component 5, thus limiting the photovoltaic module and the track. The top of the track mounting component 5 is embedded with a bearing 6, and a locking rod 7 is rotatably connected inside the bearing 6. The bottom end of the adjusting bolt 4 has a slot 8 for engaging with the locking rod 7. A fixing component 9 is bolted to one side of the track mounting component 5 and fitted with the adjusting bolt 4. A gasket 14 is provided on the top of the fixing component 9, and the inside of the gasket 14 fits against the surface of the adjusting bolt 4. The gasket 14 is used to prevent the adjusting bolt 4 and the fixing component 9 from directly contacting and causing friction, thereby reducing the wear rate of the fixing component 9. By setting an upper pressure plate 2 and a lower abutment plate 3, under the adjustment action of the adjusting bolt 4, the upper pressure plate 2 and the lower abutment plate 3 are... Fixed to the top and bottom of the photovoltaic panel respectively, after the track mounting component 5 and the track are installed, the photovoltaic module can be adjusted without disassembling the adjusting bolt 4, and no handling is required, so there will be no friction between the photovoltaic panel and the track. The position of the lower clamping plate 3 can be adjusted by setting the adjusting bolt 4, and the distance between the lower clamping plate 3 and the upper pressure plate 2 can be adjusted according to the different thicknesses of the photovoltaic panel. After adjustment, the contact area between the upper pressure plate 2, the connecting component 1 and the lower clamping plate 3 and the photovoltaic panel will not decrease, and the stability will not change after adjustment.

[0029] Brief description of usage: In use, slide the track mounting piece 5 and the limiting piece 10 onto the track. Then, insert the photovoltaic panel of the photovoltaic module between the upper pressure plate 2 and the lower clamping plate 3. Insert the adjusting bolt 4 into the connector 1 and thread it through the lower clamping plate 3 until the slot 8 and the locking rod 7 at the bottom of the adjusting bolt 4 are engaged. The adjusting bolt 4 will then rub against the locking rod 7 and rotate under the action of the bearing 6. After the adjusting bolt 4 and the locking rod 7 contact, the adjusting bolt 4 continues to rotate. The lower clamping plate 3 on the surface of the adjusting bolt 4 will move up or down under the guidance of the guide groove 12 and the guide rod 13. When the adjusting bolt 4 rotates in the forward direction, the lower clamping plate 3 moves upward; when the adjusting bolt 4 rotates in the reverse direction, the lower clamping plate 3 moves downward. When the lower clamping plate 3 moves upward, the top of the lower clamping plate 3 will contact the bottom of the photovoltaic panel. After the lower clamping plate 3 contacts the photovoltaic panel, the lower clamping plate 3 will no longer be able to move upward under the threaded connection of the adjusting bolt 4, and the adjusting bolt 4 will also be unable to be turned. At this time, the adjusting bolt 4 and the fixing part 9 will contact and limit the fixing part 9 and the track mounting part 5. The position of the lower clamping plate 3 will no longer move. The lower clamping plate 3 and the upper pressure plate 2 will clamp the photovoltaic panel. The track mounting part 5 and the track are independently connected and do not contact the photovoltaic panel. The position of the photovoltaic panel can be adjusted at will under the sliding action of the track mounting part 5 and the track. By rotating the limiting bolt 11 downward to contact the track, the track mounting part 5, the limiting part 10 and the pressed photovoltaic panel can be limited.

After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
