Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic panel fixing frames, and in particular to a spliced solar photovoltaic panel fixing frame. Background Art

[0002] A solar photovoltaic panel mounting system, also known as a solar racking system or solar mounting system, is a structural framework designed specifically to support and securely mount solar photovoltaic panels. Its primary purpose is to ensure that the panels are effectively placed on the ground, rooftop, or other suitable locations, and oriented at the optimal angle to the sun, thereby maximizing solar energy absorption and improving energy conversion efficiency. These mounting systems are typically constructed from sturdy, corrosion-resistant metal materials (such as aluminum or stainless steel) to ensure stable operation in all weather conditions.

[0003] Currently, photovoltaic panel mounting brackets are often provided as discrete components before being transported to the installation site for ease of transportation and handling. However, in the construction of large-scale photovoltaic power plants, this approach makes on-site bracket assembly and inter-unit connection extremely complex and time-consuming. This is especially true when multiple photovoltaic panels need to be connected to expand the work area. Position calibration and precise docking become even more difficult, increasing both construction difficulty and project completion time. Therefore, to improve assembly efficiency and reduce on-site work time, it is necessary to optimize the existing process. A spliced solar photovoltaic panel mounting bracket is proposed to simplify on-site installation steps, accelerate project progress, and reduce labor costs and construction difficulty.

Therefore, they cannot be understood as limiting the present invention.

[0028] Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The technical solutions of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. It should be noted that the technical features involved in the different embodiments of the present invention described below may be combined with one another as long as they do not conflict with one another.

[0029] Embodiment: A spliced solar photovoltaic panel fixing frame, such as Figures 1-6 Shown, including: The rotating bracket 1 has a mounting plate at the top thereof which is driven by a motor to rotate. The mounting plate is driven by the motor to rotate in the front-rear direction. A connecting seat 11 is fixedly provided on the mounting plate at the top of the rotating bracket 1, allowing the connecting seat 11 to rotate and tilt in the front-rear direction along with the mounting plate. There are four hinged seats 2, which are respectively arranged at the four sides of the connecting seat 11. An extension plate 21 is hingedly provided on the hinged seat 2. The extension plate 21 can rotate along the corresponding hinged seat 2, thereby presenting two usage states of unfolding or folding, so that the whole can be flexibly adjusted according to the usage space to reduce unnecessary space occupation. A rotating disk 22 with an upper and lower layer structure is rotatably provided in the middle of the connecting seat 11, and a gripping block 24 for gripping operation is provided on the top of the rotating disk 22. The surface of the gripping block 24 is arranged with strip-shaped recesses. The pattern is suitable for fitting the position of the hand for gripping and providing the friction required for gripping to ensure stability during operation. Semi-annular grooves 221 are circumferentially opened on each layer of the rotating disk 22, and the number and layout of the extension plates 21 are adapted. A protruding rod 231 is slidably embedded in each semi-annular groove 221. A stop plate 23 is provided between the two upper and lower opposite protruding rods 231. The stop plate 23 is respectively slidably penetrated through the adjacent side edges of the connecting seat 11 and the adjacent hinge seat 2, and the end of the stop plate 23 is engaged with the corresponding side extension plate 21 to fix the unfolded extension plate 21; Specifically, the rotating disk 22 is rotated to drive the protruding rod 231 to slide along the semi-annular groove 221 synchronously with the rotation, thereby pushing the corresponding supporting plate 23 to retract or extend the sliding operation, see Figure 4 The butt plate 23 is in an extended state, thereby cooperating with the unfolded extension plate 21 to be inserted and fixed to it, so as to resist the unfolded extension plate 21 and ensure its unfolded position state. On the contrary, when the extension plate 21 is folded, the rotating disk 22 is rotated in the opposite direction to retract the butt plate 23, thereby releasing its restriction on the extension plate 21, allowing the extension plate 21 to rotate freely and fold closed, thereby reducing the overall floor space. Through the integrated movable structure, the disassembly and assembly of loose parts is reduced, thereby facilitating subsequent transportation and processing.

[0030] The connecting mechanism 3 is provided on two extension plates 21 opposite to each other in the front and rear directions. The connecting mechanism 3 includes a guide sleeve 31. The guide sleeve 31 is provided with two groups. The two groups of guide sleeves 31 are fixedly provided on the extension plates 21 on the front and rear sides respectively. The two guide sleeves 31 of the same group are respectively located on the left and right sides of the end of the corresponding extension plate 21. A connecting rod 32 is provided on each guide sleeve 31 in a sliding manner. The connecting rod 32 is a sliding operation in the front and rear directions. A single seat 321 is provided at the end of the connecting rod 32. An elastic member 33 is provided between the connecting rod 32 and the corresponding guide sleeve 31. In the embodiment, the elastic member 33 is a spring; and the front and rear extension plates 21 are further provided with a number and layout of retaining seats 34 that are compatible with the guide sleeve 31. The retaining seats 34 are all provided with a straight groove 341 and a cross groove 342. The straight seat 231 of the connecting rod 32 coincides with the straight groove 241, and the position of the cross groove 342 is close to the connecting rod 32 on the same side. When two different retaining seats 34 are connected and fitted, the connecting rod 32 is allowed to pass through the retaining seat 34 on the same side and enter the other retaining seat 34 and engage with its cross groove 342 to splice and fix the photovoltaic panels.

[0031] When the cam 32 is in the closed position, the cam 321 is in the closed position, and the cam 322 is in the closed position, so that the cam 322 is in the closed position.

[0032] like Figure 1 、 Figure 7 and Figure 8 As shown, it also includes an extension rod 4 that is slidably inserted into the left and right extension plates 21 respectively. A movable seat 41 is provided on the end of the extension rod 4 that is close to each other. The movable seat 41 is slidably matched with the extension plate 21 on the same side. By using the extension rod 4 that allows sliding adjustment, the left and right extension plates 21 can be adjusted to provide placement space for the left and right sides of the photovoltaic panel.

[0033] like Figure 2 、 Figure 3 、 Figure 5 and Figure 7As shown, it also includes a fixing bolt 211. The ends of the extension rod 4 and the front and rear extension plates 21 are all penetrated and threaded with a fixing bolt 211. The top of the fixing bolt 211 is provided with a buckle plate 212. The buckle plates 212 around are used to buckle and fix the position of the photovoltaic panel.

[0034] like Figure 7 and Figure 8 As shown, it also includes a guide rod 42, and the extension plates 21 at the left and right positions are provided with jacks 213 arranged symmetrically in front and back. A group of guide rods 42 is provided in the movable seat 41, and a dial plate 43 is provided between the guide rods 42 on the same side for sliding symmetrically in front and back. A second elastic member 45 is provided between the two dial plates 43 and is respectively sleeved on the corresponding guide rod 42. In this embodiment, the second elastic member 45 is a spring, and the dial plates 43 are provided on the side away from each other with an insertion rod 44 that is plugged into the jack 213 on the same side to fix the position of the corresponding extension rod 4.

[0035] like Figure 1 、 Figure 9 and Figure 10 As shown, a cleaning mechanism 5 is provided on the extension rods 4 on both sides, and the cleaning mechanism 5 includes an infusion pump 51 fixedly mounted on the left and right sides of the rotating bracket 1 respectively, and a mounting seat 53 is provided on the front and rear sides of the end of the extension rod 4. A nozzle 54 is hingedly provided on the mounting seat 53, so that the nozzle 54 can rotate and operate, thereby folding and fitting the adjacent extension plate 21 to reduce the occupied space. A rotary spray gun 55 is arranged on the nozzle 54, and a connecting pipe 52 is connected between the nozzle 54 and the water outlet of the infusion pump 51 on the same side. Water can be supplied by the infusion pump 51, so that the water flows through the connecting pipe 52 to the nozzle 54, and finally is sprayed out by the spray gun 55. The rotary spraying method is used to make the water spraying range wider, effectively ensuring the uniformity and comprehensiveness of cleaning.

[0036] like Figure 10 As shown, it also includes a guide frame 56. A guide frame 56 is provided at the bottom of each nozzle 54. A positioning seat 57 is slidably provided on the guide frame 56 and is plugged into the mounting seat 53 on the same side to fix the position of the corresponding nozzle 54. An elastic member 58 is provided between the positioning seat 57 and the adjacent guide frame 56. In this embodiment, the elastic member 58 is a spring, which can provide an elastic force for the positioning seat 57 to reset. The cooperation of the above components can be used to fix the position of the nozzle 54 in different rotation states.

[0037] like Figure 1As shown, it also includes an adjustment seat 6. The adjustment seat 6 is slidably provided on the rotating bracket 1. The adjustment seat 6 slides in the up and down directions. Articulated rods 61 are hingedly provided on the left and right sides of the adjustment seat 6 respectively. The bottom ends of the articulated rods 61 are hingedly provided with bottom plates 62. By utilizing flexible sliding and articulated node settings, a more flexible and adaptable auxiliary bracket is provided for the rotating bracket 1, so that the supporting effect of the rotating bracket 1 is enhanced, and the overall stability of the frame is effectively consolidated, thereby ensuring the stable installation of the photovoltaic panel.

[0038] When transporting the entire fixed frame, since the components of the frame are a movable integrated structure, during transportation, it is only necessary to rotate and retract the extension plates 21 to attach the components to the rotating bracket 1, thereby reducing the overall footprint of the frame and saving transportation space. When installing the photovoltaic panel later, first place the rotating bracket 1 at the installation location and take corresponding fixing measures, then lift each extension plate 21 upwards, so that each extension plate 21 rotates at the corresponding connection point on the hinge seat 2, and after the extension plate 21 is unfolded, you can hold the holding block 24 and rotate it, thereby driving the rotating disk 22 to rotate accordingly, so that the protruding rod 231 embedded in the semi-annular groove 221 instantly follows the rotation and moves along the direction of the semi-annular groove 221. From then on, the protruding rod 231 on all sides gradually moves outward, thereby driving the connected push plate 23 to push outward, and the push plate 23 moves in accordance with the movement and passes through the connecting seat 11 and the corresponding hinge seat 2, so that the end of the push plate 23 is inserted into the extension plate 21 on the same side, thereby supporting the unfolded extension plate 21 to fix the unfolded position of the extension plates 21 on all sides, and then according to To adjust the size of the photovoltaic panels to be installed, push the extension rods 4 on both sides to move. First, pull the two side plates 43 on one extension rod 4 so that the two slide closer to each other along the guide rod 42 on the corresponding moving seat 41. The elastic member 45 is deformed accordingly, and then the insertion rod 44 is freed from the restriction of the insertion hole 213. Then, the extension rod 4 can be pulled freely to extend the length of the extension plate 21. After the extension rod 4 has finished moving, the plate 43 can be released. The elastic member 45 is no longer restricted and is reset. Then, the two plates 43 slide away from each other under the elastic force, so that the plates 43 are reset. Then, the insertion rod 44 is reinserted into the insertion hole 213 at the corresponding position to fix the position of the extension rod 4 after adjustment. Then repeat the above operation to adjust the extension rod 4 on the other side. Then the photovoltaic panel can be placed on the extension plate 21 so that each side of the photovoltaic panel is embedded in the buckle plate 212 at the corresponding position, thereby buckling and fixing the four sides of the photovoltaic panel. When the photovoltaic panel needs to be spliced, another photovoltaic panel is attached together with the frame so that the two photovoltaic panels are attached to each other, and then the connecting rod 32 at one of the positions is pushed to make the connecting rod 32 approach the two card seats 34 on the side. As the connecting rod 32 moves, it slides on the guide sleeve 31, and the elastic member is engaged. 33 deforms accordingly until the connecting rod 32 passes through the last locking seat 34. Then, the connecting rod 32 is rotated 90 degrees and the connecting rod 32 is released. Under the restoring force of the elastic member 33, the connecting rod 32 returns to its original direction. However, due to the shape restriction of the straight seat 321, it is locked into the cross groove 342 of the locking seat 34, thereby connecting and fixing the frames on both sides. Then, the operation is repeated to connect the connecting rod 32 on the other side, so that the photovoltaic panels on both sides and the frames are connected and assembled. When the photovoltaic panels need to be cleaned, the nozzles 54 on both sides are first unfolded, and then the infusion pump 51 is filled with water, so that the water flows through the infusion pump 51, the connecting pipe 52, the nozzle 54 and the corresponding spray gun 55 to spray out to clean the photovoltaic panels.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
