Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic engineering technology, and in particular relates to a wind-resistant mechanism for photovoltaic panels used in photovoltaic engineering. Background Technology

[0002] Photovoltaic engineering is a general term for technologies and related facilities that use the photovoltaic effect to convert solar energy into electrical energy. The main equipment or materials involved include photovoltaic panels, inverters, brackets and supporting electrical equipment. Since photovoltaic panels are generally installed at an angle, they are easily blown away and damaged by strong winds. Therefore, in order to avoid the impact of wind on photovoltaic panels, wind-resistant structures are usually installed on the photovoltaic panel brackets.

[0003] A wind-resistant fixing device for a ground-mounted photovoltaic panel is disclosed in document CN218416249U. The device includes an installation plate and a photovoltaic panel body fixed to the top of the installation plate. The photovoltaic panel body has a windbreak plate on its side wall. The bottom of the installation plate is fixed with legs in a rectangular array. The bottom of each of the legs is fixed with a base. The side walls of the legs and the bases are all equipped with fixing rods. The side walls of the windbreak plate are fixed with multiple telescopic rods in a rectangular array. The top of the windbreak plate is fixed with a first wind guide plate at an angle. The side walls of the windbreak plate are detachably fixed with a second wind guide plate in a triangular structure. The multiple telescopic rods are elastically inserted into the multiple fixing rods. The top of the positioning rod is fixed at the center of the bottom wall of the installation plate.

[0004] However, it still has the following drawbacks in practical use:

[0005] 1. The photovoltaic panel windproof fixing device mentioned above has a wind deflector installed on the support leg by a fixing rod. The wind deflector, the first wind guide plate and the second wind guide plate are used to prevent wind from the main body of the photovoltaic panel. However, it is not convenient to quickly install and fix the wind deflector on the support leg during use. This makes it difficult to quickly repair the wind deflector and other windproof structures when they are damaged, resulting in poor practical performance.

[0006] 2. The photovoltaic panel wind-resistant fixing device mentioned above has a triangular second wind guide plate. The second wind guide plate guides the airflow at the rear end of the photovoltaic panel body. However, in use, because the second wind guide plate is an integral structure and it is not convenient to store the second wind guide plate, the presence of the second wind guide plate will affect the inspection of the staff when the wind force is small.

[0007] To address these issues, we provide a wind-resistant mechanism for photovoltaic panels used in photovoltaic projects. Utility Model Content

[0008] The purpose of this utility model is to provide a wind-resistant mechanism for photovoltaic panels used in photovoltaic projects. The side plate and the fixed plate are installed on the bracket by connecting strips, and the connection between the side plate and the bracket is strengthened by abutment rods. This solves the problem of the existing wind-resistant structure being inconvenient to install and disassemble. At the same time, the threaded rod drives the moving plate to move, and the moving plate drives the movable plate to move, which solves the problem of the existing windproof structure being inconvenient to store.

[0009] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0010] This utility model is a wind-resistant mechanism for photovoltaic panels used in photovoltaic engineering, including a support frame and a photovoltaic panel body fixedly connected to the support frame. A fixing plate is provided at the rear end of the support frame through a fixing component, and a windproof component is also provided at the rear end of the fixing plate.

[0011] The fixing assembly includes side plates that are fixedly connected to both sides of the front end face of the fixing plate. Each side plate has a threaded abutment rod that passes through its outer wall. One end of the abutment rod is connected to both sides of the bracket. Each side plate has a connecting strip that is rotatably connected to its front end face. The left and right adjacent connecting strips are connected to each other.

[0012] The windproof assembly includes multiple mounting plates movably connected to the rear end of a fixed plate via dampers. Movable blocks are movably connected to both sides of the rear end face of the mounting plates. The same movable plate is movably connected to the rear end of the mounting plates. A threaded rod is threaded through the end face of the middle mounting plate. The rear end of the threaded rod is fixedly connected to the center of the front end face of the movable plate. Movable plates are rotatably connected to both sides of the movable plate. The end of the movable plate away from the movable plate is rotatably connected to the rear end face of the movable block.

[0013] A further feature of this invention is that: one end of the abutting rod is fixedly connected to an abutting plate, the end of the abutting plate away from the abutting rod is respectively attached to the outer walls of both sides of the bracket, and the other end of the abutting rod is fitted with a rotating cap.

[0014] A further feature of this invention is that each end face of the connecting strip is provided with a positioning hole, and each positioning hole is fitted with a positioning post with clearance, and the rear end of each positioning post is fixedly connected to the bracket.

[0015] A further feature of this invention is that: a fixing rod is fixedly connected to all four sides of the bottom of the bracket, and a pre-embedded block is fixedly connected to the bottom end of each fixing rod.

[0016] A further feature of this invention is that the same insert rod passes through one end of the connecting strips that are close to each other, and the top of each insert rod is fixedly connected to a limiting plate.

[0017] A further feature of this invention is that: mounting bases are fixedly connected to both sides of the rear end face of the mounting plate, and sliding rods are fixedly connected between the mounting bases; the moving blocks are respectively slidably sleeved on both sides of the outer wall of the sliding rods.

[0018] A further feature of this invention is that: a limiting rod is fixedly connected to both the upper and lower ends of the front end face of the movable plate, and the front ends of the limiting rods respectively movably pass through the upper and lower end faces of the mounting plates and are threaded with limiting nuts.

[0019] A further feature of this invention is that a handwheel is fixedly connected to the front end of the threaded rod, and the handwheel is located in front of the mounting plate.

[0020] This utility model has the following beneficial effects:

[0021] This utility model, by setting a fixing component, first places the fixing plates on both sides of the rear end of the bracket, so that the side plates are located on both sides of the bracket's legs. Then, the rotating cap is rotated, which drives the abutment rod and the abutment plate to move, so that the abutment plates are respectively attached to both sides of the bracket's legs. Finally, the connecting strip is rotated so that the left and right adjacent connecting strips come into contact with each other, and the insertion rod passes through the connecting strip. This realizes the installation of the fixing plate and the windproof structure on the bracket, which facilitates the installation and disassembly of the fixing plate and the windproof structure, and thus facilitates the inspection and replacement of the windproof structure.

[0022] This invention features a windproof component. By rotating a handwheel, the handwheel drives a threaded rod to rotate synchronously. The threaded connection between the threaded rod and the mounting plate causes the movable plate to move relative to the mounting plate. This, in turn, applies an external force to the movable plate, causing it to move. This allows for the retraction and extension of the movable plate, facilitating the windproof structure's operation and preventing it from interfering with the workers' inspection work when the wind is light.

Example 2

[0042] Please see Figure 1 , Figure 6 , Figure 7 and Figure 8 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but differs from the previous embodiment in that: a windproof component 5 is also provided at the rear end of the fixed plate 4. The windproof component 5 includes a mounting plate 501, a damper 502, a moving block 503, a moving plate 504, a threaded rod 505, and a movable plate 506.

[0046] A handwheel 505a is fixedly connected to the front end of the threaded rod 505, and the handwheel 505a is located in front of the mounting plate 501.

[0047] The rest of the structure is the same as in Example 1.

[0048] The operation process of this embodiment is as follows: rotate the handwheel 505a, which drives the threaded rod 505 to rotate synchronously. Under the action of the threaded connection between the threaded rod 505 and the mounting plate 501, the moving plate 504 moves relative to the mounting plate 501. Thus, the moving plate 504 applies an external force to the movable plate 506, causing the movable plate 506 to move, thereby realizing the opening and closing of the movable plate 506.
