[0002] The foundation pit is the pit that needs to be excavated when the house building, municipal engineering or underground building is under construction. In order to guarantee the safety of the foundation pit construction and the main underground structure and the surrounding environment is not damaged, the foundation pit support, precipitation and excavation are needed, and the corresponding survey, design, construction and monitoring are carried out, and the comprehensive engineering of this system is called the foundation pit engineering. The foundation pit engineering is the construction operation facing various foundation soils and complex environmental conditions, and there are uncertain factors such as external force uncertainty, deformation uncertainty, soil uncertainty and some accidental changes. Therefore, it is unrealistic to accurately predict the changes of the foundation pit engineering support structure and the surrounding soil in the construction process in the engineering design stage. Therefore, for large and complex engineering, the prototype monitoring is the key to guarantee the foundation pit engineering. The prism position change amount is used as the measurement value of the foundation pit, that is, the lifting device of the prism is set on the detection point, the prism position is monitored through the total station outside the foundation pit, and then the foundation pit deformation amount is monitored.

The 90-degree damping shaft and the second shaft are arranged in parallel and extend to both sides of the base.

[0004] The above-mentioned patent mentions in the specification that "through the level monitoring, when the angle of the supporting plate 2 is in the horizontal state, the 90-degree damping shaft 5 makes the first gear 7 keep the fixed state at this time, so that the prism can be kept in the horizontal state, that is, the prism basically keeps the vertical rising state in the whole process, and the error influence caused by the prism inclined rising is avoided", but the present base is limited by the fixed installation mode when facing the irregular foundation pit or needing to accurately monitor the deformation amount from multiple specific angles. The prism cannot be flexibly adjusted in position and posture according to the actual demand, for example, in the narrow and complex structure corner of the foundation pit, or in the case of needing to capture the deformation information of the foundation in all directions and multiple views. The existing base cannot fully play a role, and therefore a prism base for foundation pit deformation detection is proposed to solve the above-mentioned problems. UTILITY MODEL CONTENTS

[0042] Specifically, the adjusting mechanism 3 enables the operator to accurately adjust the angle of the support plate 2 according to the actual ground conditions, so that the detection component 6 always maintains the best detection posture, whether it is the horizontal or vertical deformation amount can be accurately captured, greatly improving the accuracy and effectiveness of detection. In actual operation, the operator can observe the specific conditions of the foundation pit ground, manually operate the adjusting mechanism 3, and adjust the angle of the support plate 2 to maintain a suitable angle relationship with the ground. The design of the adjusting mechanism 3 also considers the convenience and flexibility of operation, so that the operator can quickly and accurately complete the angle adjustment operation.

[0043] The adjusting mechanism 3 includes a fixed plate 301, which is fixedly connected to the inside of the base 1. The fixed plate 301 provides a mounting and fixing base for the subsequent components of the adjusting mechanism 3, ensuring the stability of the adjusting mechanism 3 inside the base 1. The inside of the fixed plate 301 is rotatably connected to a control column 306. The control column 306 serves as an operating component of the adjusting mechanism 3. The operator can adjust the angle of the support plate 2 by rotating the control column 306. The outside of the control column 306 is fixedly connected to a damping shaft 302, which can provide a certain resistance during adjustment to make the adjustment process more stable and avoid inaccurate angle adjustment of the support plate 2 due to rapid adjustment. The outside of the control column 306 is fixedly connected to a first gear 303, which is coupled to a chain 304. Rotating the first gear 303 can drive the chain 304 to move, thereby adjusting the angle of the support plate 2. The inside of the chain 304 is coupled to a second gear 308.

[0044] Specifically, in the adjustment process, the operator can feel the moderate resistance brought by the damping shaft 302, so as to more accurately control the angle adjustment of the support plate 2.

The first gear 303 is fixedly connected outside the control column 306, the first gear 303 is coupled with the chain 304, and the chain 304 can be driven to move by rotating the first gear 303, so as to realize the adjustment of the angle of the support plate 2. In the adjustment process, the second gear 308 can effectively transmit the movement of the chain 304 to the subsequent components, ensuring the stability and accuracy of the adjustment process. At the same time, the existence of the second gear 308 also increases the transmission ratio of the adjustment mechanism 3, so that the operator can realize larger angle adjustment of the support plate 2 through smaller rotation angle. The control assembly 309 plays a role in facilitating the operator to control the starting transmission effect.

[0045] The chain 304 is rotatably connected outside the connecting column 305, and the connecting column 305 transmits the movement of the chain 304 to the support plate 2, so that the support plate 2 can be angle-adjusted with the movement of the chain 304. The top end of the connecting column 305 is fixedly connected to the bottom end of the support plate 2, so as to ensure that the support plate 2 can accurately rotate with the movement of the connecting column 305. The base 1 is fixedly connected outside the spring 307, and the top end of the spring 307 is fixedly connected to the bottom end of the support plate 2. The spring 307 can play a role in buffering and supporting during the adjustment of the support plate 2, so that the adjustment of the support plate 2 is more stable, and the stability of the support plate 2 is also enhanced. The control column 306 is rotatably connected inside the base 1, so as to ensure that the control column 306 can flexibly rotate inside the base 1 and effectively control the adjustment mechanism 3.

[0046] Specifically, in the adjustment process of the support plate 2, the spring 307 can effectively absorb and buffer the impact force generated during the adjustment process, reducing the shaking and vibration of the support plate 2. At the same time, the spring 307 can also provide a certain supporting force when the support plate 2 is stationary, ensuring the stability of the support plate 2 and preventing it from tilting or moving due to external force. The operator can easily rotate the control column 306 to realize various operations of the adjustment mechanism 3, thereby meeting different detection needs.

[0047] Referring to Figure 1 , Figure 2 and Figure 4The limiting mechanism 4 comprises a driving assembly 401, the driving assembly 401 comprising a motor 40101, the motor 40101 serving as a power source of the limiting mechanism 4 and being capable of providing stable driving force, so that the limiting mechanism 4 can accurately limit the detection component 6; the driving end of the motor 40101 is fixedly connected with a rotating shaft 40102, the rotating shaft 40102 is fixedly connected with a rotating rod 402 outside, the rotating rod 402 rotates under the driving of the motor 40101, both ends of the rotating rod 402 are rotatably connected with transmission rods 403, the far sides of the two transmission rods 403 are rotatably connected with sliding blocks 404, the rotating rod 402 transmits the power of the motor 40101 to the transmission rods 403, the transmission rods 403 convert the rotating motion of the rotating rod 402 into the linear motion of the sliding blocks 404, so as to realize the clamping and limiting of the detection component 6.

[0048] Specifically, the rotating rod 402, the transmission rods 403 and the sliding blocks 404 are designed according to the mechanical transmission principle, and have the advantages of simple structure and high transmission efficiency; during the limiting operation, the motor 40101 drives the rotating rod 402 to rotate, the rotating rod 402 transmits the power to the sliding blocks 404 through the transmission rods 403, so that the sliding blocks 404 slide linearly inside the supporting plate 2; by controlling the rotating direction and angle of the motor 40101, the motion direction and distance of the sliding blocks 404 can be accurately controlled, so as to realize the accurate clamping and limiting of the detection component 6.

[0049] The top ends of the two sliding blocks 404 are fixedly connected with limiting blocks 405, the sliding blocks 404 slide inside the supporting plate 2 under the driving of the transmission rods 403, so as to realize the position adjustment of the limiting blocks 405; the limiting blocks 405 directly contact with the detection component 6, and clamp both sides of the detection component 6, so as to realize the limiting and fixing of the detection component 6, ensure the position stability of the detection component 6 during the detection, and ensure that the limiting blocks 405 can accurately clamp the detection component 6, prevent the detection component 6 from shaking or moving; the top end of the supporting plate 2 is provided with a sliding groove, the outside of the sliding block 404 is slidably connected inside the sliding groove, the sliding groove provides guidance and limitation for the sliding of the sliding block 404, so as to ensure that the sliding block 404 can accurately slide within the specified range, and thus realize the effective limiting of the detection component 6.

The sliding groove provides guidance and limitation for the sliding of the sliding block 404, ensuring that the sliding block 404 can accurately slide within a specified range, thereby effectively limiting the detection component 6.

[0051] With reference to Figure 1 , Figure 2 and Figure 5 , the fixing mechanism 5 comprises a fixing cylinder 501, the top end of the fixing cylinder 501 being rotatably connected to the bottom end of the base 1. The fixing cylinder 501 provides a space for the installation and movement of the sliding cylinder 502 and the limiting column 503, and also ensures the stability of the connection between the fixing mechanism 5 and the base 1. The sliding cylinder 502 is slidingly connected to the inside of the fixing cylinder 501, and can slide within the fixing cylinder 501. By adjusting the position of the sliding cylinder 502, the height of the base 1 can be adjusted, so that the entire prism base can adapt to different depths of foundation pits. The limiting column 503 is slidingly connected to the inside of the sliding cylinder 502, and is used to fix the position of the sliding cylinder 502. When the limiting column 503 slides into the hole in the fixing cylinder 501, the position of the sliding cylinder 502 is fixed, thereby achieving the locking of the height of the base 1. The front end of the limiting column 503 is fixedly connected with the telescopic column 504, which provides guidance and support for the sliding of the limiting column 503, ensuring that the limiting column 503 can smoothly slide within the sliding cylinder 502.

[0052] Specifically, the limiting column 503 is designed with a reasonable structure and size, which can be well matched with the hole in the fixing cylinder 501. During the adjustment process, the operator can press or pull the limiting column 503 to make it slide into or out of the hole in the fixing cylinder 501, thereby fixing and unlocking the position of the sliding cylinder 502. This design is simple and convenient to operate, and can quickly and accurately lock and adjust the height of the base 1.

[0053] The outer part of the telescopic column 504 is sleeved with spring two 505, which can provide elastic force during the sliding process of the limiting column 503. When the limiting column 503 is pressed to slide into the inside of the sliding cylinder 502, the spring two 505 is compressed to store elastic potential energy. When the limiting column 503 is released, the spring two 505 releases the elastic potential energy to push the limiting column 503 out of the inside of the sliding cylinder 502, thereby fixing the position of the sliding cylinder 502.

The bottom end of the limiting block 405 is slidingly connected to the top end of the support plate 2, ensuring that the limiting block 405 can be stably installed on the support plate 2 to provide reliable limiting action for the detection component 6. The sliding connection between the limiting block 405 and the support plate 2 adopts high-precision machining process and surface treatment technology, which can ensure that the limiting block 405 stably slides on the support plate 2 without loosening or shaking. In actual use, the limiting block 405 can effectively limit and fix the detection component 6, ensuring the position stability of the detection component 6 during detection, thereby improving the accuracy and reliability of the detection result.

[0055] Working principle: when the operator needs to monitor the deformation of the foundation pit, the base 1 is placed in the inside of the foundation pit, at this time the detection component 6 is placed at the top of the support plate 2, by starting the motor 40101, the motor 40101 drives the rotating rod 402 to rotate in the inside of the support plate 2, so that the transmission rod 403 pulls the sliding block 404 to slide in the inside of the support plate 2, so that the limiting block 405 self-adaptingly clamps and limits the detection component 6, so as to ensure the stability of the position of the detection component 6 during detection, when disassembly is needed, the motor 40101 is started in reverse rotation, so that the limiting block 405 cancels the limiting of the detection component 6, through quick disassembly and assembly, the preparation time before monitoring is reduced, and the transportation of the detection component 6 is facilitated.

[0056] When the base 1 is in the inside of the foundation pit, if the ground is inclined, the control column 306 outside the first gear 303 or the second gear 308 can be manually rotated, so that the chain 304 moves outside the first gear 303 and the second gear 308, and through the transmission of the connecting column 305, the support plate 2 drives the detection component 6 to rotate horizontally, so as to adjust the angle of the support plate 2, so as to ensure that the detection component 6 is at a horizontal angle, and ensure the accuracy of monitoring, and the operator can adjust the height of the base 1 as needed, the inside of the sliding cylinder 502 is provided with a plurality of limiting columns 503, by pressing the limiting column 503 to slide into the inside of the sliding cylinder 502, the position of the fixing cylinder 501 and the sliding cylinder 502 is limited, by adjusting the position of the sliding cylinder 502, after adjustment, the spring two 505 in the inside of the sliding cylinder 502 pushes the limiting column 503 to slide out of the inside of the sliding cylinder 502, so that the limiting column 503 slides into the hole in the inside of the fixing cylinder 501, so as to fix the position of the sliding cylinder 502, so as to adjust the height.
