[0026] In the present application, the support column 6 is used to support and fix the entire protective structure. By inserting the insertion rod 9 into the ground, the support column 6 is made vertical to support the first protective net 1 and the second protective net 10. By arranging the base frame 8 and the reinforcing rod 7 at the bottom of the support column 6, the stability and strength of the support column 6 can be improved.

[0027] Furthermore, the opening and closing mechanism 2 includes an electric push rod 201 and a telescopic frame 205, one end of the electric push rod 201 is fixedly connected to the second mounting shaft 202, the output end of the electric push rod 201 is fixedly connected to the connecting shaft 204, the connecting shaft 204 is rotatably mounted on one end of the telescopic frame 205, one side of the mounting sleeve 3 is fixedly connected to the mounting block 203, the second mounting shaft 202 is rotatably mounted on the mounting block 203, both ends of the telescopic frame 205 are respectively rotatably mounted on the two mounting sleeves 3, and the shelves near the two ends of the telescopic frame 205 are respectively rotatably mounted on the first mounting shafts 11 at both ends.

[0028] In the present application, the electric push rod 201 is used in conjunction with a mobile power supply. Before the protective equipment is put into use, several first protective nets 1 and second protective nets 10 are in a folded state. When in use, the electric push rod 201 is powered by the mobile power supply, and the output end of the electric push rod 201 extends, driving the telescopic frame 205 to extend, thereby allowing the first protective net 1 and the second protective net 10 to open. The telescopic frame 205 can make the protective structure occupy a smaller space when retracted and provide a larger protection area when expanded. By connecting the telescopic frame 205 to the middle of the first protective net 1 and the second protective net 10, it can be quickly expanded and folded under the action of the electric push rod 201, thereby improving the convenience of operation.

During operation, loosen the fastening screw 13 to move the limit plate 15 away from the support column 6, so that the installation sleeve 3 can slide up or down along the support column 6, driving the first protective net 1 to move up or down. After adjustment, tighten the fastening screw 13 to make the limit plate 15 press against the support column 6, so that the position of the installation sleeve 3 is fixed, thereby completing the adjustment of the first protective net 1 and the second protective net 10.
