Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic panels, and particularly relates to a photovoltaic panel installation structure for preventing loosening. Background Art

[0002] Photovoltaic power generation is a technology that directly converts light energy into electrical energy by using the photovoltaic effect at the semiconductor interface. It has the advantages of no pollutant emissions and no energy consumption. Photovoltaic power generation technology is also a hot issue in current social research. In photovoltaic power generation, photovoltaic energy panels are used more frequently. They are devices that absorb sunlight and directly or indirectly convert solar radiant energy into electrical energy through the photovoltaic effect or the photochemical effect.

[0003] For example, the patent application No. 201720803705.6 discloses a photovoltaic panel installation structure, including a bottom plate. One side of the upper end of the bottom plate is hinged with a fixing plate. A support rod is fixed at the lower end of the fixing plate. An adjusting mechanism is arranged at the lower end of the support rod. Two chutes are arranged at equal intervals on the fixing plate. Sliders are installed in the chutes. Two parallel support frames are arranged on both sides of the fixing plate. First threaded through holes are arranged on the support frames. Screws penetrate through the first threaded through holes. A rotating wheel is fixed at the upper end of the screw. Second threaded through holes corresponding to the screws are arranged on the photovoltaic panel. Through the combination of the adjusting mechanism, the screw and the photovoltaic panel, the utility model realizes the angle adjustment of the photovoltaic panel and is convenient for the disassembly of the photovoltaic panel, which is suitable for popularization.

[0004] The prior art enables the photovoltaic panel to be adjusted in angle through the cooperation of the screw and the rotating wheel, and also facilitates the installation and disassembly of the photovoltaic panel, reducing the maintenance time. However, there are still the following deficiencies: First, in the prior art, at the connection between the column and the embedded pile body, a screw connection method is usually adopted on the surface of the column. Such a connection method is not only inconvenient for installation, but also prone to loosening due to external forces in bad weather, resulting in the inclination of the photovoltaic panel and reducing the conversion efficiency. Second, when installing a photovoltaic panel frame on a site with loose soil, the embedded ground pile will tilt in the soil due to insufficient supporting force, increasing the manual maintenance cost. Summary of the Utility Model

[0005] In order to overcome the deficiencies of the prior art, the utility model provides a photovoltaic panel installation structure that prevents loosening. By setting a connector and a fixing member, the connection degree between the upright column and the embedded ground pile can be effectively increased, enabling the photovoltaic panel frame to be more stably installed on the embedded ground pile. It can effectively resist the influence of strong wind weather and other external natural forces, ensuring the safe operation of the photovoltaic panel frame. The connection between the connector and the fixing member is more convenient, making the installation process simpler, reducing the working difficulty during the assembly process, and improving work efficiency. The setting of the pile body can provide strong support for the upright column. Through the setting of the fixing plate, the friction between the pile body and the soil can be increased, and the soil above the fixing plate can increase the weight of the pile body, reducing tilting or damage caused by wind force.

[0006] In order to achieve the above object, the utility model provides the following technical solution: a photovoltaic panel installation structure that prevents loosening, including a connector. A plurality of spherical grooves are provided on the inner wall of the connector, and steel balls are provided in the inner cavities of the plurality of spherical grooves. A return spring is provided on the outer surface of the connector, and a sliding block is provided outside the return spring. A stop block is provided on the inner wall of the sliding block, and an inclined groove is provided below the stop block. A convex block is provided on the end face of the connector, and a fixing member is provided below the connector. The convex block is inserted into the interior of the fixing member, and a circular groove is provided on the outer surface of the fixing member. The steel balls can slide inside the circular groove. The steel balls can move between the spherical grooves and the circular groove, and together with the sliding block, a clamping effect can be achieved. Through the cooperation of the convex block and the fixing member, the connector can be fixed above the fixing member.

[0007] Preferably, a pile body is provided below the fixing member, and the fixing member is threadedly connected to the pile body. A load-bearing plate is provided on the inner wall of the pile body, and the convex block abuts against the end face of the load-bearing plate. Through holes are provided on the outer surface of the pile body. The load-bearing plate can distribute the pressure brought by the connector within the pile body, preventing the connector from being damaged and improving the service life of the device.

[0008] Preferably, a movable plate is provided inside the pile body. A plurality of first connecting members are provided at the bottom of the movable plate, and a plurality of connecting rods are rotatably provided between the plurality of first connecting members. A second connecting member is rotatably provided at one end of each of the plurality of connecting rods, and fixing plates are provided on the end faces of the plurality of second connecting members. Third connecting members are provided at one end of each of the plurality of fixing plates, and the third connecting members are fixedly connected to the pile body. When the fixing plates are opened outwards, they will squeeze the surrounding soil, making the soil more solid. After filling the soil above the fixing plates, the friction between the fixing plates and the soil can be increased to fix the position of the pile body, preventing the pile body from tilting. Or when the pile body is pulled outwards by an external force, the fixing plates will increase the contact between the pile body and the soil, preventing the pile body from being pulled out by the external force.

[0009] Preferably, a bearing sleeve is provided at the axis of the load-bearing plate, a threaded rod is provided inside the bearing sleeve, a threaded sleeve is provided outside the threaded rod and inside the movable plate, and the threaded sleeve is rotatably connected to the outer surface of the threaded rod. The bearing sleeve can make the threaded rod rotate independently and can play a positioning role to prevent the threaded rod from tilting.

[0010] Preferably, a cross hole is provided on the top of the threaded rod, and a worker can rotate the threaded rod through the cross hole.

[0011] Preferably, a column is arranged above the connecting head, a triangular connecting piece is rotatably arranged above the column, an inclined beam is arranged above the triangular connecting piece, a plurality of purlins are arranged above the inclined beam, and a plurality of photovoltaic panels are arranged above the plurality of purlins.

[0012] Preferably, a drill bit is provided at the bottom of the pile body, which can break the soil and facilitate the installation of the pile body.

[0013] In summary, compared with the prior art, the beneficial effects of this solution are:

[0014] (1) In the present invention, by providing the connector and the fixing member, the connection between the column and the pile body is more tightly secured to prevent loosening caused by severe weather such as strong winds. The load-bearing plate can withstand the pressure from the column and transfer the pressure to the inside of the pile body, thereby increasing the pressure-bearing capacity of the device and prolonging the service life of the device.

[0015] (2) In the present invention, the fixing plate can be opened and closed through the through hole on the surface of the pile body. The fixing plate can compact the soil near the pile body and increase the friction between the pile body and the soil to prevent the pile body from tilting due to loose soil. After the fixing plate is opened, the soil above the fixing plate is compacted to prevent the pile body from being pulled upward. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0026] Embodiment 1:

[0027] Referring to Figure 3 , Figure 4 , Figure 7 , Figure 8 , a photovoltaic panel installation structure for preventing loosening, including a connector 1. A plurality of spherical grooves 2 are provided on the inner wall of the connector 1. Steel balls 3 are provided in the inner cavities of the plurality of spherical grooves 2. A return spring 4 is provided on the outer surface of the connector 1. A slide block 5 is provided outside the return spring 4. A stop block 6 is provided on the inner wall of the slide block 5. An inclined groove 7 is provided below the stop block 6. A protrusion 8 is provided on the end face of the connector 1. A fixing member 9 is provided below the connector 1. A cavity for connection is provided at the center of the fixing member 9. The protrusion 8 is inserted into the cavity of the fixing member 9. A circular groove 10 is provided on the outer surface of the fixing member 9. The steel ball 3 can slide inside the circular groove 10. The steel ball 3 can move in the spherical groove 2 and move in the circular groove 10, and cooperate with the slide block 5 to achieve a clamping effect. Through the cooperation of the protrusion 8 and the fixing member 9, the connector 1 can be fixed above the fixing member 9.

[0028] Referring to Figure 7 , Figure 8The steel ball 3 can roll in the spherical groove 2 because the stopper 6 on one side of the sliding block 5 abuts against the steel ball 3, and a part of the steel ball 3 can slide from the spherical groove 2 to the circular groove 10, so the steel ball 3 will extend a part of the outer spherical surface from one side of the spherical groove 2 to the inside of the circular groove 10 for clamping, but the steel ball 3 will not fall from the spherical groove 2. In this solution, the number of steel balls 3 is consistent with that of the spherical groove 2. The specific number is not restricted in this solution and can be set according to specific circumstances to ensure the processing effect.

[0029] When installing the connecting head 1 and the fixing part 9, by toggling the sliding block 5 upwards, the return spring 4 is squeezed by the stopper 6, and the sliding block 5 drives the stopper 6 to move upwards, and the protrusion 8 under the connecting head 1 is inserted along the cavity wall of the fixing part 9. During the insertion, the outer surface of the fixing part 9 will touch the steel ball 3. During this process, the steel ball 3 moves in the opposite direction, and a part of the outer spherical surface of the steel ball 3 will extend from the spherical groove 2 to the inclined groove 7, but the steel ball 3 will not completely fall off from the spherical groove 2. At this time, the connecting head 1 can be connected with the fixing part 9. After the connection is completed, the sliding block 5 is released, and the return spring 4 is restored downward. The return spring 4 pushes the sliding block 5 to move downward, and the sliding block 5 drives the stopper 6 to move downward. When the stopper 6 resists the steel ball 3, a part of the steel ball 3 rolls in the spherical groove 2 to the circular groove 10, but the steel ball 3 will not completely fall off from the spherical groove 2. At this time, the steel ball 3 will be stuck at the connection between the circular groove 10 and the spherical groove 2, forming a clamping connection, thereby completing the clamping and fixing process.
