DETAILED DESCRIPTION

[0018] The utility model is further described below in conjunction with the accompanying drawings: Embodiment 1:

[0019] See attached Figure 1-5In the present embodiment, a construction foundation pit enclosure device includes a column 1 and a slide groove 4. The slide grooves 4 are processed on the four sides of the outer wall of the column 1 respectively. The inner wall of the slide groove 4 is plugged with a baffle 5. The baffle 5 can be pulled upward under the force to detach from the inner wall of the slide groove 4. A bracket 7 is fixedly connected to the lower front of the baffle 5. The left and right sides of the lower front of the baffle 5 are connected to a control structure 2. The top of the column 1 is connected to a fixed structure 3. The top of the column 1 is processed with a round mouth, and the bottom of the column 1 is fixedly connected to an insertion rod 8.

[0020] The control structure 2 includes a bent plate 201 and a horizontal plate 202. The rear end faces of the two bent plates 201 are respectively fixed to the left and right sides of the lower front of the baffle 5. The inner wall of the bent plate 201 is plugged into the outer wall of the horizontal plate 202. The horizontal plate 202 can move up and down on the inner wall of the bent plate 20 under force. The inner wall of the horizontal plate 202 is threadedly connected with a screw rod 203. The top of the screw rod 203 is fixedly connected with a handle 204. The handle 204 is convenient for driving the screw rod 203 to rotate. The outer wall of the screw rod 203 is rotatably connected to the inner wall of the bracket 7. The screw rod 203 is rotated by the inner wall bearing of the bracket 7 under force. The rear end face of the horizontal plate 202 fits with the front of the baffle 5.

[0021] By holding the handle 204 in the control structure 2 and rotating it, the rotating handle 204 rotates the screw 203, and the rotating screw 203 drives the cross plate 202 to move downward on the inner wall of the bent plate 201, and then the cross plate 202 gradually moves downward. The cross plate 202 will block the gap under the baffle 5, and can prevent children and animals from drilling through the gap at the bottom of the baffle 5. The bent plate 201 restricts the cross plate 202, ensuring that the cross plate 202 can only move up and down, thereby improving the protection performance of the building foundation pit enclosure device and eliminating the use limitations of the building foundation pit enclosure device.

[0022] The fixing structure 3 includes a vertical rod 301 and a square plate 302. The bottom of the vertical rod 301 is fixedly connected to the top of the column 1. The outer wall of the vertical rod 301 is plugged into the circular opening of the outer wall of the square plate 302. The square plate 302 is subjected to force and moves up and down through the outer wall of the vertical rod 301. The inner wall of the square plate 302 is rotatably connected with a bolt 303. The bolt 303 is subjected to force and rotates through the inner wall bearing of the square plate 302. The outer wall of the bolt 303 is threadedly connected to the top circular opening of the column 1.

[0023] Working principle:

[0024] Installation of building foundation pit protection device:

[0025] Make the left and right sides of the baffle 5 respectively plug into the outer wall slide groove 4 of the column 1, then make the outer wall of the insertion rod 8 plug into the ground, make the bottom of the column 1 fit into the ground, then the outer wall circular mouth of the square plate 302 is plugged into the outer wall of the vertical rod 301, and then the bolt 303 is rotated to make the outer wall of the bolt 303 gradually connected with the top thread of the column 1. As the bolt 303 gradually rotates downward, it will move the square plate 302 downward, so that the bottom of the square plate 302 is aligned with the top of the column 1, and the square plate 302 presses the top of the baffle 5 to complete the position fixation of the baffle 5.

[0026] Gap shielding at the bottom of the building foundation pit protection device:

[0027] Hold the handle 204 and rotate it. The rotating handle 204 rotates the screw rod 203. The rotating screw rod 203 drives the horizontal plate 202 to move downward on the inner wall of the curved plate 201. Then the horizontal plate 202 gradually moves downward. The horizontal plate 202 will block the gap under the baffle 5 to prevent children and animals from drilling through the gap at the bottom of the baffle 5. The curved plate 201 restricts the horizontal plate 202 to ensure that the horizontal plate 202 can only move up and down. Embodiment 2:

[0028] See attached Figure 1-5 : In this embodiment, a construction foundation pit enclosure device also includes a mesh plate 6, and the outer wall of the mesh plate 6 is fixedly connected to the inner wall of the baffle 5.

[0029] Working principle:

[0030] The mesh plate 6 ensures the enclosure function while being able to observe the condition of the foundation pit. Pedestrians passing by can see the internal condition, and the display of danger is more intuitive.
