Description

Technical Field

[0001] The present invention belongs to the technical field of photovoltaic solar panel brackets, and in particular relates to a photovoltaic solar panel bracket and an installation method thereof. Background Art

[0002] When installing solar panels, a photovoltaic solar panel bracket is often needed. It not only serves as a key structure for supporting and fixing photovoltaic solar panels, but also provides a stable installation foundation for solar panels to ensure that solar panels can be firmly placed in a suitable position. For example, the publication number is: CN217362986U. A photovoltaic solar panel mounting bracket for power generation includes a base plate, two groups of base plates are arranged at intervals, and a telescopic component is arranged between the two groups of base plates. The telescopic component is used to adjust the spacing between the two groups of base plates to adapt to solar panels of different widths; the utility model facilitates the adjustment of the spacing between the two groups of base plates by setting two groups of connecting rods, which can not only adapt to solar panels of different widths but also facilitate the storage of the base plates, saving transportation space. Furthermore, the mounting plate is supported by the support rod, and the user can select the socket for the plug rod to be connected according to the actual fixed angle. When adjusting, it only needs to press the plug rod to disengage it from the socket and connect it to the appropriate socket. At the same time, during transportation and storage, the mounting plate can be slid and placed on the inner side of the accommodating groove, thereby further reducing the occupied space.

[0003] The problem with the prior art is that when using the above-mentioned solar panel bracket, it is necessary to rotate the two double-headed screws separately to adjust the angle of the mounting plate. However, this adjustment method has obvious disadvantages. First, it greatly reduces the speed of angle adjustment. Second, it is difficult to ensure that the number of turns of the two double-headed screws is completely consistent, and it is also impossible to ensure that the inclination angles of the two mounting plates remain consistent, thereby weakening the stability of the solar panel after installation. Thirdly, the double-headed screws will become loose during long-term use, which will reduce the stability of the entire bracket. Summary of the invention

However, this adjustment method has obvious disadvantages: first, it greatly reduces the speed of angle adjustment; second, it is difficult to ensure that the number of turns of the two double-headed screws is completely consistent, and it is also impossible to ensure that the inclination angles of the two mounting plates remain consistent, thereby weakening the stability of the solar panel after installation; thirdly, the double-headed screws will become loose during long-term use, which will reduce the stability of the entire bracket.

[0008] As a preferred embodiment of the present invention, both ends of the upper surface of each chassis body are fixedly connected with a second rotating block, and each mounting frame is rotatably connected to the second rotating block at the front end of each chassis body.

[0009] As a preferred embodiment of the present invention, a movable groove is formed on a side of each mounting bracket close to the angle adjustment mechanism, and fixing holes are formed on both sides of each mounting bracket.

[0010] As a preferred embodiment of the present invention, mounting holes are provided on opposite sides of the support frame and the mounting frame.

[0011] As a preferred embodiment of the present invention, the angle adjustment mechanism includes two first support rods and two second support rods, each of the first support rod and the second support rod form a group, the second support rod on each group of the support rods is respectively rotatably connected to the second rotating block at the rear end of each base frame body, the first support rod and the second support rod on each group of the support rods are connected by a threaded rod, the thread grooves of the two threaded rods are in opposite directions, the rear end of the threaded rod is rotatably connected to the first support rod, and the front end of the threaded rod is threadedly connected to the second support rod, a gear is fixedly sleeved on the middle part of each of the threaded rods, and a plurality of locking holes are arranged in a circle on each of the gears.

[0012] As a preferred embodiment of the present invention, an electric push rod is arranged above each of the first support rods, and the electric push rod is fixedly connected to the upper surface of the first support rod through two mounting blocks. A slide groove is provided on the upper surface of the front end of each of the second support rods, and each of the fixing mechanisms is respectively arranged in each slide groove.

[0013] As a preferred embodiment of the present invention, each of the fixing mechanisms includes a connecting rod, which is fixedly installed in a slide groove, and both ends of each of the connecting rods are sleeved with springs, one end of the spring is fixedly connected to the inner wall of the slide groove, and the other end of the spring is fixedly connected to a trapezoidal block, and the trapezoidal block slides on the outer surface of the connecting rod, and a connecting block is fixedly connected to the outer side of each of the trapezoidal blocks, and the connecting block is adapted to the fixing hole.

[0014] A method for installing a photovoltaic solar panel bracket, the installation method comprising the following steps: S1. Before installing the solar panels, the two chassis bodies need to be squeezed. Under the action of the central axis, the two pulleys will slide in the limit grooves. During this process, the two gears will gradually approach each other until they mesh with each other. S2. Next, one of the gears is rotated, and the two threaded rods can be synchronously driven to rotate through the meshing connection between the gears, thereby driving the second support rod on each side to move in a direction away from or close to the gear. As the second support rod moves, the angle between the second support rod and the mounting frame can be adjusted; S3. After the angle adjustment is completed, the two base frames are simultaneously pulled outward until the distance between the two base frames is adjusted to a position that matches the width of the solar panel. Angle seats can be set on the base frames to install the adjusted base frames in the appropriate place through the angle seats. S4. After the width adjustment and the angle adjustment are completed, the electric push rod is started. The output end of the electric push rod passes through the locking hole and continues to extend toward the fixing mechanism. At this time, the two trapezoidal blocks on each side are squeezed and move away from each other. The spring contracts accordingly. Due to the movement of the trapezoidal block, the connecting block on it is synchronously driven to move until the connecting block is inserted into the fixing hole. In this way, the second support rod and the mounting frame are fixed. When the electric push rod continues to drive the output end to extend, the output end passes through the mounting hole on the rear side of the mounting frame and is inserted into the mounting hole on the support frame. This can play a role in initially fixing the support frame, which is conducive to improving the installation efficiency of the subsequent support frame. S5. The output end of the electric push rod is inserted into the locking groove to lock the gear to avoid the threaded rod from loosening during use, thereby preventing the stability of the solar panel from being reduced.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention not only locks the gears through the arrangement of the electric push rod to prevent the threaded rod from loosening during use; at the same time, the cooperation with the fixing mechanism can firmly fix the second support rod and the mounting frame. Secondly, the support frame can be initially fixed on the mounting frame by means of the cooperation with the mounting hole, thereby improving the subsequent installation speed of the support frame.

[0016] 2. The present invention arranges two gears and two reverse threaded rods. When one of the gears is rotated, the other gear will rotate synchronously when adjusting the angle. This not only can adjust the angles of the two mounting frames at the same time, but also can ensure that the angles of the mounting frames on both sides are adjusted consistently. This improves the angle adjustment efficiency while also improving the accuracy of the angle adjustment, thereby avoiding shaking of the solar panel due to inconsistent tilt angles of the two mounting frames, thereby reducing the stability of the solar panel.

[0023] In the present application, the setting of the base frame mechanism 1 can adjust the distance between the two base frame bodies 101 so as to fix solar panels of different widths and improve the application range of the bracket.

[0024] like Figure 1 , Figure 6 As shown, a movable groove 201 is formed on one side of each mounting bracket 2 close to the angle adjustment mechanism 3 , and fixing holes 202 are formed on both sides of each mounting bracket 2 .

[0025] It should be noted that when adjusting different angles, the second support rod 302 and the mounting bracket 2 can be fixed according to the fixing holes 202 at different positions to increase the range of angle adjustment.

[0026] like Figure 1 , Figure 6 As shown, mounting holes 6 are provided on opposite sides of the support frame 5 and the mounting frame 2 .

A sliding groove 3021 is opened on the upper surface of the front end of each second support rod 302, and each fixing mechanism 4 is respectively arranged in each sliding groove 3021.

[0029] In the present application, the setting of the electric push rod 306 not only plays a locking role on the gear 304 to prevent the threaded rod 303 from loosening during use; at the same time, in cooperation with the fixing mechanism 4, the second support rod 302 and the mounting frame 2 can be firmly fixed, and secondly, the support frame 5 can be initially fixed on the mounting frame 2 by means of cooperation with the mounting hole 6, thereby improving the subsequent installation speed of the support frame 5; It should be noted that the installation of a power storage device on the bracket can store the electric energy converted by the solar panel and can also provide a power source for the electric push rod 306; through the arrangement of two gears 304 and two reverse threaded rods 303, when adjusting the angle, when one of the gears 304 is rotated, the other gear 304 is rotated synchronously, which can not only synchronously adjust the angles of the two mounting frames 2, but also ensure that the angle adjustment of the mounting frames 2 on both sides is consistent, thereby improving the angle adjustment efficiency and the accuracy of the angle adjustment, avoiding the shaking of the solar panel due to the inconsistent tilt angles of the two mounting frames 2, thereby reducing the stability of the solar panel.

[0030] like Figure 4 , Figure 5 , Figure 6 As shown, each fixing mechanism 4 includes a connecting rod 401, which is fixedly installed in the slide groove 3021.

[0032] A method for installing a photovoltaic solar panel bracket, the installation method comprising the following steps: S1. Before installing the solar panel, the two base frame bodies 101 need to be squeezed. Under the action of the central shaft 103, the two pulleys 105 will slide in the limit groove 1011. During this process, the two gears 304 will gradually approach each other until they mesh with each other. S2. Next, one of the gears 304 is rotated. Through the meshing connection between the gears 304, the two threaded rods 303 can be synchronously driven to rotate, thereby driving the second support rod 302 on each side to move away from or close to the gear 304. With the movement of the second support rod 302, the angle between the second support rod 302 and the mounting frame 2 can be adjusted; S3.

An angle seat can be set on the base frame body 101, and the adjusted base frame body 101 can be installed in a proper place through the angle seat; S4. After the width adjustment and the angle adjustment are completed, the electric push rod 306 is started. The output end of the electric push rod 306 passes through the locking hole 3041 and continues to extend toward the direction of the fixing mechanism 4. At this time, the two trapezoidal blocks 403 on each side are squeezed and move away from each other. The spring 402 contracts accordingly. Due to the movement of the trapezoidal block 403, the connecting block 404 thereon is synchronously driven to move until the connecting block 404 is inserted into the fixing hole 202. In this way, the second support rod 302 is fixed to the mounting frame 2. When the electric push rod 306 continues to drive the output end to extend, the output end passes through the mounting hole 6 on the rear side of the mounting frame 2 and is inserted into the mounting hole 6 on the support frame 5. This can play a role in preliminarily fixing the support frame 5, which is conducive to improving the subsequent installation efficiency of the support frame 5. S5. The output end of the electric push rod 306 is inserted into the locking groove to lock the gear 304, thereby preventing the threaded rod 303 from loosening during use, thereby preventing the stability of the solar panel from being reduced.

[0033] In summary: this photovoltaic solar panel bracket and installation method, through the setting of the electric push rod 306, not only locks the gear 304 to prevent the threaded rod 303 from loosening during use; at the same time, in cooperation with the fixing mechanism 4, the second support rod 302 and the mounting frame 2 can be firmly fixed, and secondly, the support frame 5 can be initially fixed on the mounting frame 2 with the help of the cooperation with the mounting hole 6, thereby improving the subsequent installation speed of the support frame 5; through the setting of the two gears 304, when adjusting the angle, when one of the gears 304 is rotated, the other gear 304 is rotated synchronously, which not only can synchronously adjust the angles of the two mounting frames 2, but also can ensure that the angle adjustment of the mounting frames 2 on both sides is consistent, thereby improving the angle adjustment efficiency while also improving the angle adjustment accuracy, thereby avoiding the shaking of the solar panel due to the inconsistent inclination angles of the two mounting frames 2, thereby reducing the stability of the solar panel.

During this process, the two gears (304) gradually approach each other until they mesh with each other. S2. Next, one of the gears (304) is rotated. Through the meshing connection between the gears (304), the two threaded rods (303) can be synchronously driven to rotate, thereby driving the second support rod (302) on each side to move in a direction away from or close to the gear (304). As the second support rod (302) moves, the angle between the second support rod (302) and the mounting frame (2) can be adjusted; S3.

In this way, the second support rod (302) and the mounting frame (2) are fixed. When the electric push rod (306) continues to drive the output end to extend, the output end passes through the mounting hole (6) on the rear side of the mounting frame (2) and is inserted into the mounting hole (6) on the support frame (5).
