[0002] Photovoltaic power generation is a technology that uses the photovoltaic effect of semiconductor interfaces to directly convert light energy into electrical energy. It is mainly composed of three parts: solar panels (modules), controllers and inverters, and the main components are composed of electronic components. After solar cells are connected in series and packaged for protection, they can form large-area solar cell modules, which are then combined with power controllers and other components to form photovoltaic power generation devices.

[0003] Existing photovoltaic power generation controllers are generally installed in control cabinets, and the control cabinets are mostly fixed directly to the ground by bolts. When the bolts are exposed to rain and sunlight, they are prone to corrosion and rust, making it difficult to remove the bolts, increasing the difficulty of later maintenance of the control cabinet. In addition, some control cabinets are installed outdoors. In order to prevent rainwater from penetrating into the control cabinet from the ground, support rods are often installed at the bottom of the control cabinet to achieve the effect of isolating the ground. However, since the control cabinet is installed too high, when encountering strong winds, the control cabinet will shake unsteadily, which can easily cause the control cabinet to topple over and be damaged. Utility Model Content

DETAILED DESCRIPTION

[0022] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure. Example 1

[0024] like Figure 1-Figure 6As shown, the utility model provides a technical solution: a control cabinet for photovoltaic power generation, including a mounting seat 1 and a cabinet 2, the top of the mounting seat 1 is provided with a mounting groove 101, the bottom of the cabinet 2 is fixedly connected with a bottom column 21, the number of the bottom columns 21 is the same as the number of the mounting grooves 101, the side of the bottom column 21 is provided with a through hole 211, both sides of the outer wall of the cabinet 2 are fixedly connected with mounting blocks 22, the inner side of the mounting block 22 is provided with a pull rod 3, the front and rear ends of the mounting seat 1 are movably installed with a crank 4, the connection structure of the two cranks 4 is the same, one end of the crank 4 is fixedly connected with a screw 41, One end of screw rod 1 41 is fixedly connected to screw rod 2 411, screw rod 1 41 and screw rod 2 411 have the same structure but opposite directions, a threaded sleeve 42 is threadedly connected to the surface of screw rod 1 41, connecting rods 43 are movably installed on both sides of the outer wall of the threaded sleeve 42, one end of the connecting rod 43 is movably connected to a slider 44, the outer wall of the mounting groove 101 is fixedly connected to a fixing seat 5, the surface of the slider 44 is movably connected to the inner wall of the fixing seat 5, one end of the slider 44 is located on the inner side of the mounting groove 101, a limit block 441 is fixedly installed on the surface of the slider 44, and the limit block 441 is located inside the fixing seat 5.

[0025] In this embodiment, the bottom column 21 at the bottom end of the cabinet 2 is placed inside the installation groove 101, and the crank 4 is turned to drive the screw 1 41 and the screw 2 411 to rotate simultaneously. The rotation of the screw 1 41 causes the threaded sleeve 42 to move on its surface, and at the same time drives the connecting rod 43 to move outward and push the slider 44, so that the slider 44 moves toward the inside of the installation groove 101 and passes through the through hole 211 inside the bottom column 21, so that the bottom column 21 is installed and fixed. At the same time, since a limit block 441 is installed on the surface of the slider 44, the limit block 441 slides inside the fixing seat 5, which can prevent the slider 44 from being pulled out from the fixing seat 5 and limit it. Example 2

[0026] like Figure 1-Figure 6 As shown, a connecting block 11 is fixedly installed on the top of the mounting seat 1, and a fixing ring 12 is fixedly connected to the top of the connecting block 11. The interior of the mounting block 22 is a hollow structure, and grooves are provided on both sides of the interior of the mounting block 22. A guide rod 23 is fixedly installed inside the groove of the mounting block 22, and a spring 24 is movably installed on the surface of the guide rod 23. A hook 31 is fixedly connected to the bottom of the pull rod 3, and a movable shaft 32 is movably installed inside the top of the pull rod 3. Both sides of the movable shaft 32 are fixedly connected with movable blocks 33, and the inner wall of the movable block 33 is slidably connected to the surface of the guide rod 23, and the bottom of the movable block 33 is movably connected to the top of the spring 24.

[0027] In this embodiment, when the cabinet 2 is connected and fixed to the mounting base 1, by pulling the pull rods 3 on both sides downward, the pull rods 3 drive the movable block 33 to move downward on the surface of the guide rod 23 during the descent process, and squeeze the spring 24 on the surface of the guide rod 23. Due to the movable connection between the pull rod 3 and the movable shaft 32, the pull rod 3 can be rotated to adjust the angle, and the bent hook 31 at the bottom of the pull rod 3 pulls the fixed ring 12, and the spring 24 rebounds to move the pull rod 3 back, so that the bent hook 31 is connected to the fixed ring 12.

[0028] The working principle of this embodiment is as follows: the bottom column 21 is placed inside the mounting groove 101, and the crank 4 is turned to drive the screw rod 41 to rotate. The rotation of the screw rod 41 causes the threaded sleeve 42 to move on its surface, and at the same time drives the connecting rod 43 to move outward and push the slider 44, so that the slider 44 moves toward the inside of the mounting groove 101 and passes through the through hole 211 inside the bottom column 21, and the bottom column 21 is installed and fixed. The pull rods 3 on both sides are pulled downward. During the descent process, the pull rods 3 drive the movable block 33 to move downward on the surface of the guide rod 23, and squeeze the spring 24 on the surface of the guide rod 23, so that the hook 31 at the bottom of the pull rod 3 pulls the fixing ring 12, and the spring 24 rebounds to cause the pull rod 3 to move back, so that the hook 31 is connected to the fixing ring 12, thereby increasing the contact force points between the cabinet body 2 and the mounting seat 1, and improving the stability of the cabinet body 2.
