The water pressure sensor body 1 and the top of the top cover plate 5 are connected with a wire 6.

[0024] Specifically, by contacting the guide mechanism 3 with the side wall of the hole, and cooperating with the elastic force of the second spring 35 and the first spring 34, the water pressure sensor body 1 can slide smoothly inside the hole to avoid being stuck inside the hole. At the same time, when the device is placed to the specified position, the device can be supported by the support mechanism 4 to ensure the stability of the device placement and improve the accuracy of the monitoring data.

[0025] The guide mechanism 3 includes a slide bar 31, a frame 32, a hinge rod 33, a second spring 35 and a roller 36. One end of the slide bar 31 is slidably connected to the vertical strip 2. The other end of the slide bar 31 is connected to the frame 32, the cross-section of the frame 32 is U-shaped, and the two ends of the roller 36 are rotatably connected in the U-shaped setting of the frame 32.

At the same time, when the rollers 36 roll, it can effectively avoid the water pressure sensor body 1 from being stuck in the hole and unable to be pulled out, thereby ensuring smooth embedding and improving work efficiency.

[0029] When the device reaches the bottom of the hole, the micro motor 43 is started, the threaded rotating rod 411 is driven to rotate by the micro motor 43, and the limiting function of the limiting bar 414 and the interaction between the threads are cooperated to enable the lifting block 412 to perform lifting and lowering movements, and push the multiple linkage rods 413 and the unfolding rod 7 to unfold around. When the unfolding rod 7 is unfolded and contacts the inner wall of the hole, the water pressure sensor body 1 is fixed, and the device can be fixed at any position in the hole, thereby improving the convenience of monitoring.
