[0027] The working principle of this utility model:

[0028] When in use, first, place the device at the specific position where the foundation pit needs to be intercepted. This step is the basis of the entire operation process, ensuring that the device can accurately control and intercept the foundation pit. Then, by adjusting the height of the telescopic rod 3, accurate interception of the foundation pit can be achieved. This process requires careful operation to ensure the accuracy of the interception effect. After adjusting the position, start the motor 13, and the transmission shaft 106 at the upper end of the motor 13 will drive the driving gear 101 to start rotating. A driven gear 102 is arranged around the driving gear 101. They realize the transmission of the driven gear 102 through the mutual meshing between the tooth surfaces. This step is the key to the operation of the entire device, ensuring that the power can be effectively transmitted to the driven gear 102. As the driven gear 102 rotates, it will drive the connecting rod 103 at the lower end of the driven gear 102 to slide on the surface of the contact groove 7. The upper end of the connecting rod 103 is connected to the transmission rod 4 through the fixed rod 105. Therefore, during the sliding process of the connecting rod 103, the transmission rod 4 will also move along the direction of the fixed groove 9. This The process realizes dynamic control of the pit interception. During the continuous sliding process, the connecting rod 103 will move outward, and finally achieve the purpose of intercepting the pit. Since the device is provided with interception mechanisms 1 all around, it is only necessary to intercept the corresponding pit surface when in use. In order to realize this function, the limit rod 205 can be pushed downward to make the baffle plate 14 at the front end of the limit rod 205 contact with the support plates 202 on both sides. Under the pressure of the baffle plate 14, the support plates 202 will slide to both sides. The groove 5 moves, thereby fixing the connecting rod 103. This step ensures that the driving gear 101 transmits the transmission to the driven gear 102, and the driven gear 102 transmits the transmission to the fixing sleeve 204, and finally the support rod in the fixing sleeve 204 transmits the transmission to the connecting rod 103. When the baffle 14 reaches the specified position, the limit rod 205 can be rotated to push the positioning block 206 on the limit rod 205 into the limit groove 207. In this way, the position of the limit rod 205 can be fixed, thereby achieving the purpose of intercepting the foundation pit.
