[0002] Photovoltaic power station refers to a photovoltaic power generation system that uses solar energy and special materials such as crystalline silicon panels, inverters and other electronic components to connect to the power grid and transmit electricity to the grid. Photovoltaic power stations are the green power development energy projects that the country encourages the most. They can be divided into independent power generation systems with batteries and grid-connected power generation systems without batteries. Solar power generation is divided into solar thermal power generation and photovoltaic power generation. The solar power that has entered commercialization at this time refers to solar photovoltaic power generation. Safety warning signs and fences need to be set up at the construction site of the photovoltaic power station to prevent unauthorized personnel from entering the construction site.

[0029] Reference Figure 1 , Figure 3 and Figure 4 As shown, a cavity is opened at the bottom of the support rod 1, and a mounting plate 12 is slidably arranged inside the cavity. A push plate 9 is rotatably embedded and installed at the bottom of the mounting plate 12. A vertical rod 8 is vertically fixed at the bottom of the push plate 9, and a support foot 7 is fixed at the vertical rod 8;

[0030] A sliding rod 91 is horizontally penetrated and fixed on the pushing plate 9. Arc-shaped guiding grooves 10 are symmetrically arranged in the cavity. The sliding rod 91 is arranged in the guiding groove 10, and the sliding rod 91 and the guiding groove 10 are cooperatively guided. A pushing spring 11 for assisting in pushing the pushing plate 9 is sleeved and installed on the vertical rod 8 in the cavity. A sliding groove 92 is vertically opened on the outer side of the support rod 1. An extending rod 13 is fixed on the outer side edge of the mounting disc 12. The extending rod 13 slides in the sliding groove 92. A sliding cavity is opened on the extending rod 13, and a positioning assembly 14 for auxiliary positioning is installed in the sliding cavity. Positioning holes 141 are symmetrically drilled on both sides of the support rod 1 corresponding to the sliding groove 92. A protruding block 131 is fixedly protruded at one end of the extending rod 13 facing the support rod 1. A receiving groove 132 is opened inside the protruding block 131.

[0031] Through the cooperation among the support feet 7, the vertical rod 8, the pushing plate 9, the sliding rod 91, the guiding groove 10, etc. arranged at the bottom of the support rod 1, when the extending rod 13 is stepped on downward, the extending rod 13 integrally slides along the sliding groove 92. During the process of the extending rod 13 being stepped on, the mounting disc 12 is driven to move downward as a whole. During the process of the mounting disc 12 moving downward, the pushing plate 9 is driven to move downward as a whole. During the process of the pushing plate 9 moving downward, the sliding rod 91 slides along the guiding groove 10, so that the vertical rod 8 rotates as a whole. During the process of the vertical rod 8 rotating, the support feet 7 are driven to rotate 90 degrees as a whole, so as to unfold the support feet 7 as a whole. During the process of the pushing plate 9 being pressed downward, the pushing spring 11 is driven to be compressed. It can make the support feet 7 be consistent with the cross bar in the transportation state, can protect the support feet 7 from rotating 90 degrees as a whole during work, so as to realize protective support, can reduce the overall floor area of the device during transportation, and can reduce the overall transportation cost during transportation.

[0032] The above-mentioned positioning assembly 14 includes a sliding rod 15 that is horizontally slidably arranged in the sliding cavity. The sliding rod 15 is in an L-shaped rod structure. The horizontal section of one end of the sliding rod 15 is in a Chinese character "zhong" shape in the vertical section. One end of the sliding rod 15 is fixed with a connecting rod. One end of the connecting rod extending into the receiving groove 132 is fixed with a positioning pin 18. The positioning pin 18 and the positioning hole 141 are cooperatively slidable. A return spring 17 for assisting in pushing the pushing disc 16 is installed in the sliding cavity.

[0033] Through the provided positioning assembly 14, when the extension rod 13 reaches the positioning hole 141, the positioning pin 18 is inserted and positioned in the positioning hole 141, thereby completing the overall positioning of the extension rod 13 and pushing the sliding rod 15 outward. In the process of the sliding rod 15 being pushed outward, the pushing plate 16 is pulled, and the reset spring 17 is compressed, and the positioning pin 18 is withdrawn from the positioning hole 141. Under the action of the pushing spring 11, the pushing plate 9 is pushed, thereby adjusting the supporting foot 7 back to the initial state, ensuring that the supporting foot 7 is in the extended state when it can be positioned, and trying to avoid the problem that the supporting foot 7 is retracted as a whole when the device is in the protective working state, causing the device to be unable to stand effectively.

[0034] Working principle:

[0035] During work, when it is necessary to protect the construction position, the support rod 1 is taken to the designated position, and the extension rod 13 is stepped down. The extension rod 13 slides as a whole along the slideway 92, and the installation plate 12 is driven to move downward as a whole during the extension rod 13 is stepped on. The installation plate 12 is driven to move downward as a whole during the downward movement of the installation plate 12. The push plate 9 is driven to move downward as a whole during the downward movement of the push plate 9. The slide bar 91 slides along the guide groove 10, so that the vertical rod 8 is rotated as a whole. The vertical rod 8 is driven to rotate the support foot 7 as a whole 90 degrees during the rotation process, so that the support foot 7 is unfolded as a whole. When the movable plate 9 is pressed downward, the push-up spring 11 is compressed. When the extending rod 13 reaches the positioning hole 141, the positioning pin 18 is inserted and positioned in the positioning hole 141, thereby completing the overall positioning of the extending rod 13 and ensuring that the supporting foot 7 is in the current state. When the overall length of the safety protection device needs to be adjusted, the supporting rod 1 is pulled to a specified length, and the positioning bolt 6 is rotated. The insert plate 3 and the positioning bolt 6 are threadedly matched, so that the positioning bolt 6 is topped at the bottom of the insertion slot 5, thereby completing the overall length adjustment of the device.

[0036] After use, the sliding rod 15 is pushed outward by the foot. In the process of the sliding rod 15 being pushed outward, the pushing plate 16 is pulled, and the reset spring 17 is compressed, and the positioning pin 18 is withdrawn from the positioning hole 141. Under the action of the pushing spring 11, the pushing plate 9 is pushed, thereby adjusting the supporting foot 7 back to the initial state.

[0037] All technical features in this embodiment can be freely combined according to actual needs.
