[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] See also Figure 1-4, the utility model provides an embodiment: a safety protection device for a deep foundation pit, including a column 1, a plurality of columns 1 are arranged in parallel, the lower end of the column 1 is fixedly connected to a supporting base plate 101, a telescopic slot 103 is provided inside the upper end of the column 1, an L-shaped cross-section fixing ring 105 is fixedly provided on the upper end surface of the column 1 and at the upper end of the telescopic slot 103, a screw 2 is provided inside the telescopic slot 103, the upper end of the screw 2 passes through the middle of the L-shaped cross-section fixing ring 105 and extends out of the upper end of the column 1 and is fixedly connected to a warning device 3, the warning device 3 includes a battery box 301 and a lampshade 302, the lampshade 302 is fixed to the upper end of the battery box 301, a warning light 303 is fixedly provided on the upper end of the battery box 301 and inside the lampshade 302, and a railing assembly 5 is fixedly connected between two adjacent columns 1.

[0024] Furthermore, the supporting base plate 101 is fixedly connected to the ground at the edge of the foundation pit by a first bolt 102 , so that the column 1 is stably fixed on the ground at the edge of the foundation pit.

[0025] Furthermore, rectangular limiting parts 104 are fixedly connected on both sides of the upper end of the telescopic groove 103, and rectangular sliding grooves 201 are provided on the end faces of both sides of the screw 2. The two rectangular limiting parts 104 slide into the two rectangular sliding grooves 201 on the screw 2 respectively, so that the screw 2 can be lifted and lowered through the telescopic groove 103. When the screw 2 is lifted and lowered, the rectangular limiting parts 104 slide along the rectangular sliding grooves 201 to prevent the screw 2 from rotating when it is lifted and lowered.

[0026] Furthermore, the upper end of the L-shaped cross-section fixing ring 105 is rotatably connected to a rotating tube 106, and an internal threaded portion 107 is fixedly provided on the inner end face of the rotating tube 106. The upper end of the screw 2 passes through the interior of the rotating tube 106 and is threadedly connected to the internal threaded portion 107. The rotating tube 106 is rotated to drive the screw 2 to rise and fall, and the screw 2 drives the warning device 3 to rise and fall, which is convenient for adjusting the height of the warning device 3 to increase the warning range of the warning device 3.

[0027] Furthermore, two parallel connecting plates 4 are fixedly connected to the upper and lower ends of both side end surfaces of the column 1.

[0028] Furthermore, the railing assembly 5 includes two parallel transverse railings 501 , a plurality of vertical railings 502 are fixedly connected between the two transverse railings 501 , and rectangular plug-in portions 503 are fixedly connected to both ends of the transverse railings 501 .

[0029] Furthermore, the rectangular plug-in parts 503 at one end of the two transverse railings 501 are respectively inserted between the two connecting plates 4 at the upper and lower ends of one side of the column 1 and fixedly connected by the second bolts 401. A guardrail unit is formed by the column 1 and the railing assembly 5, and deep foundation pits are maintained by multiple guardrail units.

[0030] Working principle: When in use, first fix the supporting base plate 101 to the ground at the edge of the foundation pit through the first bolt 102 to ensure the stability of the column 1. Then, adjust the height of the warning device 3 according to actual needs. This is achieved by rotating the rotating tube 106 at the upper end of the L-shaped cross-section fixing ring 105. Since the inner side of the rotating tube 106 is provided with an internal threaded portion 107, which matches the thread on the upper end of the screw 2, the rotation of the rotating tube 106 will drive the screw 2 to move up and down in the telescopic groove 103. At the same time, the rectangular slide grooves 201 on both sides of the screw 2 slide along the rectangular limit portion 104 inside the telescopic groove 103 to ensure that the screw 2 remains vertical and does not rotate during the lifting process. When the screw 2 is adjusted to the appropriate height, the warning light 303 (powered by the battery box 301) on the warning device 3 will be lit to provide a night warning function. Next, assemble the railing assembly 5. The rectangular connectors 503 at each end of the handrail assembly 5 are inserted between the connecting plates 4 at the upper and lower ends of the sides of two adjacent columns 1, and secured with second bolts 401 to ensure the stability between the handrail assembly 5 and the columns 1. In this way, multiple columns 1 and handrail assemblies 5 are interconnected to form a complete deep foundation pit safety protection device, which not only effectively prevents people from accidentally entering the deep foundation pit area, but also provides a clear warning sign through the warning device 3 at night, enhancing construction safety.

[0031] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
