[0002] The foundation pit is a pit dug at the foundation design location according to the base elevation and foundation plane dimensions. Before excavation, the excavation plan should be determined based on geological and hydrological data and the conditions of nearby buildings, and waterproofing and drainage should be done. If the excavation is not deep, the slope can be used to stabilize the soil slope, and the slope size is determined according to relevant construction regulations.

[0003] In this process, the foundation pit needs to be surrounded, warned, and protected to prevent passers-by and vehicles from falling in. This is the role of the above-mentioned safety protection structure. Generally, the safety protection structure can be called a guardrail, but the existing foundation pit safety protection structure is in use. Since the shape and length of the foundation pit safety protection structure are fixed structures, when the foundation pit is large or the shape of the foundation pit is irregular, the foundation pit safety protection structure is not convenient to change and splice according to the shape of the foundation pit, resulting in insufficient applicability of the foundation pit safety protection structure. At night when the light is dim, the protective device lacks a lighting structure, so that the protective device does not have a warning function, which still makes safety accidents prone to occur.

Therefore, a foundation pit safety protection device for foundation pit excavation and a method of using it can be designed, and the LED lighting panel can be opened and closed by pulling down the protective partition net, so that the protection device has a warning function when the light is dim at night, thereby reducing the occurrence of safety accidents, and when the device needs to be rotated, expanded and spliced, the rotating seat is rotated on the outside of the device body through the third transmission gear, so that the staff can rotate the device at an angle as needed, thereby improving the applicability of the device, and the connection positioning block is extended outward through the knob, so that multiple devices are convenient for splicing and positioning through the connection positioning block and the connection positioning groove.

When the device needs to be rotated, expanded and spliced, the rotating seat 3 is rotated on the outside of the device body 1 through the third transmission gear 14, so that the staff can rotate the device at an angle as needed, thereby improving the applicability of the device. During the rotation of the first transmission gear 11 inside the rotating seat 3, the first transmission gear 11 expands the expansion seat 6 outward through the rack 10, and extends the connecting positioning block 19 outward through the knob 7, so that multiple devices are conveniently spliced ​​and positioned through the connecting positioning block 19 and the connecting positioning groove 18, which solves the problem that the existing foundation pit safety protection structure is not convenient to change and splice according to the shape of the foundation pit, resulting in insufficient applicability of the foundation pit safety protection structure. At night when the light is dim, the protective device lacks a lighting structure, so that the protective device does not have a warning function, resulting in the problem that safety accidents are still prone to occur.
