The second threaded rod is driven to rotate by rotating the second handle, and the second threaded block and the mounting leg are driven to move horizontally by the second threaded rod to adjust the position of the mounting leg. After the adjustment is completed, the mounting leg is installed on the prefabricated base by the preset bolts. However, the following defects still exist:

[0003] When the photovoltaic panel is installed inside the frame, it is compressed and fixed by the closed airbag, but it is difficult to limit the upper and lower sides of the photovoltaic panel, which affects the installation stability of the photovoltaic panel. Utility Model Content

The first pull rod 4068, the first pull rod 4068 passes through the outside of the first side tube 4065, the frame 1 and the support plate 2 limit the side wall and bottom of the photovoltaic panel respectively, and after pushing the connecting plate 405 toward the side of the frame 1, the rotating plate 402 is pushed to rotate around the rotating seat 401 through the connecting rod 404, so that the rotating plate 402 is parallel to the photovoltaic panel, so that the rotating plate 402 limits the top of the photovoltaic panel, thereby fixing the photovoltaic panel, facilitating the installation and protection of the photovoltaic panel.

[0025] The auxiliary fixing member 407 includes a suction cup 4071 fixedly mounted on the inner surface of the rotating plate 402 near the frame 1, a negative pressure cylinder 4072 is mounted on the other side of the rotating plate 402, the negative pressure cylinder 4072 is connected to the suction cup 4071, a screw cylinder 4073 is fixedly mounted on the end of the negative pressure cylinder 4072, a piston 4074 is movably mounted inside the negative pressure cylinder 4072, a connecting rod 4075 is mounted on the side of the piston 4074 away from the rotating plate 402, a screw 4076 is mounted on one end of the connecting rod 4075, the screw 4076 is threadedly connected to the screw cylinder 4073, a second side cylinder 4078 is fixedly mounted on the top of the negative pressure cylinder 4072, a second clamping rod 4079 is movably mounted inside the second side cylinder 4078, and the bottom end of the second clamping rod 4079 is connected to the connecting rod 407 5, a third spring 40710 is installed at the top of the second clamping rod 4079, and a second pull rod 40711 is installed at the top of the second clamping rod 4079. The second pull rod 40711 passes through the outside of the second side tube 4078, and a second clamping groove 4077 is opened on the outer wall of the connecting rod 4075. When the screw 4076 is turned, the second clamping groove 4077 can be driven to move to a position corresponding to the second clamping rod 4079. After the rotating plate 402 rotates around the rotating seat 401, the end face of the suction cup 4071 on the rotating plate 402 contacts the surface of the photovoltaic panel. After the screw 4076 is turned, the piston 4074 is pulled toward the side away from the suction cup 4071, so that negative pressure is generated between the suction cup 4071 and the photovoltaic panel, thereby further fixing the photovoltaic panel.

[0026] Working principle: When installing the photovoltaic panel, install the photovoltaic panel to the inner side of the frame 1 so that the bottom wall of the photovoltaic panel contacts the top wall of the support plate 2, and the side wall of the photovoltaic panel contacts the protective pad 3, then push the connecting plate 405 to move toward the side of the frame 1, and push the rotating plate 402 to rotate downward around the rotating seat 401 through the connecting rod 404 until the rotating plate 402 is parallel to the photovoltaic panel. At this time, the end face of the suction cup 4071 is in close contact with the surface of the photovoltaic panel, thereby limiting the top wall of the photovoltaic panel and fixing the photovoltaic panel. At this time, the first clamping groove 4064 on the sliding plate 4062 corresponds to the first clamping rod 4066, and the first clamping rod 4066 is clamped into the first clamping groove 4064 to clamp and fix the rotating plate 402;

[0027] Since the end face of the suction cup 4071 is in close contact with the surface of the photovoltaic panel, the screw 4076 is turned. Since the screw 4076 is threadedly connected to the screw barrel 4073, the piston 4074 is driven to move toward the side away from the suction cup 4071, so that the suction cup 4071 and the photovoltaic panel are fixed by negative pressure adsorption, thereby improving the fixing stability of the photovoltaic panel. After the connecting rod 4075 rotates, when the second slot 4077 moves to the position corresponding to the second clamping rod 4079 along with the connecting rod 4075, the second clamping rod 4079 is clamped into the second slot 4077 under the elastic force of the third spring 40710, thereby fixing the position of the piston 4074 and ensuring the negative pressure adsorption effect.
