DETAILED DESCRIPTION

[0017] The following is combined with Figure 1 This application is described in further detail.

[0018] The embodiment of the present application discloses a foundation pit slope displacement detection device.

[0019] Reference Figure 1The foundation pit slope displacement detection device includes a fixed frame 1 fixed to the bottom of the foundation pit, a horizontal base 2 is welded to the upper end of the fixed frame 1, and the lower end of the fixed frame 1 is inserted into the bottom of the foundation pit and is located near the foot of the slope. A vertical fixed plate 3 is welded to one end of the base 2, and a horizontal shield 4 is fixed to the upper end of the fixed plate 3. The base 2 is provided with a through groove 21, a horizontal slide bar 22 is welded in the through groove 21, and a vertical moving plate 5 is slidably connected to the slide bar 22. The moving plate 5 is arranged opposite to the fixed plate 3, and the moving plate 5 is located below the shield 4. A horizontal cross bar 51 is welded to the middle of the outer wall of the side of the moving plate 5 away from the fixed plate 3. The cross bar 51 is hollow and the end is open. A horizontal telescopic rod 52 is threaded through the open end of the cross bar 51. One end of the telescopic rod 52 is threadedly connected to the cross bar 51, and the other end of the telescopic rod 52 extends out of the cross bar 51 and is hinged with a push block 53, so that the push block 53 can contact the slope of any inclination angle.

[0020] Reference Figure 1 An elastic component 6 is provided between the fixed plate 3 and the movable plate 5. The elastic component 6 includes an extension block 61 welded to the fixed plate 3. The extension block 61 is hollow inside and has an open end. A horizontal displacement block 62 is slidably passed through the open end of the extension block 61. The extended end of the displacement block 62 is fixed to the side wall of the movable plate 5. The displacement block 62 is sleeved with a spring 63. One end of the spring 63 is welded to the end of the extension block 61, and the other end of the spring 63 is fixed to the side wall of the movable plate 5.

[0021] Reference Figure 1 The fixed plate 3 is provided with a detection element 7 for real-time detection of the displacement of the slope. The detection element 7 is a through-beam distance-finding sensor. The transmitter of the through-beam distance-finding sensor is installed on the fixed plate 3, and the receiver of the through-beam distance-finding sensor is installed on the movable plate 5, and the transmitter and the receiver are arranged opposite to each other. An acoustic and visual alarm 8 is installed on the outer wall of the fixed plate 3. The acoustic and visual alarm 8 is electrically connected to the detection element 7 through a controller. When the foundation pit slope is displaced and a lateral driving force is generated on the push block 53, the push block 53 drives the movable plate 5 to move toward the direction close to the fixed plate 3. The through-beam distance-finding sensor can detect the change of the spacing between the fixed plate 3 and the movable plate 5 in real time, and is electrically connected to the acoustic and visual alarm 8 through the controller. When the change of the spacing between the fixed plate 3 and the movable plate 5 is detected, the controller controls the acoustic and visual alarm 8 to provide an acoustic and visual alarm to the outside world, reminding the outside surrounding personnel to avoid danger in time and make corresponding safety treatment on the slope. Since the circuit connection of the through-beam distance-finding sensor and the connection setting with the acoustic and visual alarm 8 are both existing technologies, they are not described here.

[0022] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
