The utility model is fixedly connected to the foundation pit support by screws or bolts. After the monitoring is completed, only the tightened nut needs to be loosened and it can be removed for recycling. The structure is simple and the operation is very convenient. The adjusting unit can conveniently adjust the prism to a suitable height by using the working principle of a gear and a rack, and the prism can be well adjusted to any angle by using the annular connecting teeth on the sliding rod.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Such as Figures 1 to 3As shown in the figure, a displacement monitoring device for foundation pit support provided by the utility model includes a bottom plate 1, a height adjustment component 2 and a monitoring component 3. A height adjustment component 2 is fixedly connected to the top of the bottom plate 1, and a monitoring component 3 is fixedly connected to the top of the height adjustment component 2. Horizontal rulers 5 are fixedly connected to the front side, rear side, left side and right side of the top of the bottom plate 1. The four corners of the bottom of the bottom plate 1 are movably connected to an adjustment component 6 through hinges, and a limit component 7 is fixedly connected to the bottom of the bottom plate 1.

[0023] Reference Figure 1 , the adjustment component 6 includes electric telescopic rods 61. The electric telescopic rods 61 are movably connected to the four corners of the bottom of the bottom plate 1 through hinges. An adjustment plate 62 is arranged at the bottom of the bottom plate 1. The output ends of the electric telescopic rods 61 are movably connected to the top of the adjustment plate 62 through hinges. Support members 8 are fixedly connected to the four corners of the bottom of the adjustment plate 62.

[0024] As a technical optimization scheme of the utility model, by setting the adjustment component 6, the electric telescopic rods 61 are movably installed on the bottom plate 1 through hinges, and then the output ends of the electric telescopic rods 61 are movably installed on the adjustment plate 62 through hinges. After the user places the device at the position to be monitored, by observing the horizontal ruler 5 and then controlling the extension or shortening of the electric telescopic rods 61 through the controller 12, the bottom plate 1 is made to be in a horizontal state, ensuring that the data acquisition of the monitoring component 3 is more accurate during measurement.

[0025] Reference Figure 3 , the support member 8 includes a support seat 81. The support seat 81 is fixedly connected to the four corners of the bottom of the adjustment plate 62 through hinges. Anti-slip grooves 82 are formed at the bottom of the support seat 81.

[0026] As a technical optimization scheme of the utility model, by setting the support member 8, the support seat 81 is movably installed on the adjustment plate 62 through hinges. The support seat 81 contacts the ground. Through the hinges, the support seat 81 can adapt to uneven ground, ensuring that the device can adapt to various terrains. And the anti-slip grooves 82 increase the friction between the device and the smooth ground, effectively preventing the device from sliding.

[0027] Reference Figure 3 , the limit component 7 includes limit rods 71. The limit rods 71 are fixedly connected to the bottom of the bottom plate 1. Limit blocks 72 are fixedly connected to the bottom of the adjustment plate 62. The bottom of the limit rods 71 penetrate through the adjustment plate 62 and the limit blocks 72 and are fixedly connected to limit balls 73.

[0028] As a technical optimization solution of the present utility model, by setting the limiting component 7, the limiting rod 71 is fixed to the bottom plate 1, then the limiting block 72 is fixed to the adjusting plate 62, and then the limiting ball 73 is fixed to the limiting rod 71. When the bottom plate 1 is adjusted, the limiting rod 71 prevents it from tipping over. Moreover, the distance between the bottom plate 1 and the adjusting plate 62 is restricted by the limiting ball 73, making the equipment more stable during use.

[0029] Reference Figure 3 , a limiting groove 9 for cooperating with the limiting ball 73 is formed at the bottom of the limiting block 72.

[0030] As a technical optimization solution of the present utility model, by setting the limiting groove 9, the limiting groove 9 is in sliding fit with the limiting ball 73. When the limiting ball 73 rotates at an angle, the limiting groove 9 makes the rotation smoother, reduces the loss during the friction of the limiting ball 73, increases its service life, and ensures the service time of the equipment.

[0031] Reference Figure 3 , through holes 10 are formed at the front, rear, left, and right sides of the top of the adjusting plate 62, and soil nails 11 are slidably connected inside the through holes 10.

[0032] As a technical optimization solution of the present utility model, by setting the through holes 10 and the soil nails 11, the soil nails 11 are slidably connected to the through holes 10. When the equipment is used on an uneven soil ground, by driving the soil nails 11 into the soil, the fixing effect of the equipment on the soil ground is increased, ensuring the stability of the equipment during use.

[0033] Reference Figure 1 , a controller 12 is fixedly connected to the left side of the front of the top of the bottom plate 1, and the controller 12 is electrically connected to the electric telescopic rod 61 through a wire.

[0034] As a technical optimization solution of the present utility model, by setting the controller 12, the controller 12 is fixed to the bottom plate 1, and then the controller 12 is electrically connected to the electric telescopic rod 61 through a wire, which facilitates the user to precisely control the extension or shortening of the electric telescopic rod 61 through the controller 12 and ensures the stability of the operation.

[0035] Working principle and usage process of the present utility model: When in use, after the user places the device at the position to be monitored, it contacts the ground through the support base 81. The support base 81 can adapt to uneven ground through the hinge. Then, by observing the spirit level 5, and precisely controlling the extension or shortening of the electric telescopic rod 61 through the controller 12, when the limiting rod 71 and the bottom plate 1 are adjusted, the device will not tip over. The limiting groove 9 enables the limiting ball 73 to rotate more smoothly during angle rotation, and the limiting ball 73 can limit the distance between the bottom plate 1 and the adjusting plate 62. Then, the monitoring component 3 is raised to the required position for monitoring through the height adjustment component 2.

[0036] In summary: For this displacement monitoring device for foundation pit support, by setting the spirit level 5, after the user places the device at the position to be monitored, the device is fixed through the support component 8. Then, by observing the spirit level 5 and controlling the adjustment component through the controller 12 to level the device, and through the limiting component 7 to make the device more stable during leveling. Then, the monitoring component 3 is raised to the required position for monitoring through the height adjustment component 2, which solves the problems that in the construction site, there are restrictions during placement, such as uneven terrain, which will increase the difficulty of placing the device, and the device does not have a leveling function. The inclination of the device will cause the monitoring to not correctly cover the area to be monitored, thus affecting the data collection accuracy.
