Therefore, in order to improve the practicability of the settlement observation device in practical applications, we propose a high-precision telescopic settlement observation device.

[0003] The prior art also has the following defects during use: The telescopic settlement observation device in the prior art has a less than ideal accuracy during the settlement observation process. When the observation device is telescopically adjusted, it is easy to affect the installation accuracy of the observation end. In addition, when observing the settlement, the device itself is affected by gravity and has the defect of aging and deformation, which makes it impossible to maintain the initial point of the settlement observation at the same point, thereby affecting the detection accuracy of the settlement observation device. When the telescopic settlement observation device in the prior art is used outdoors, since the settlement observation device needs to conduct long-term and stable observation of the observation point, and there is a large amount of dust and water vapor in the outdoor environment, which in turn blocks and affects the observation end, it will affect the detection effect of the observation end and reduce the accuracy of the settlement observation.

DETAILED DESCRIPTION

[0016] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0017] like Figure 1 - Figure 5 As shown, a high-precision telescopic settlement observation device proposed by the present invention comprises a sleeve 1, a telescopic rod 2, an inner tube 3 and a protection box 4. The protection box 4 is a hollow cubic structure, and an opening is arranged on the front of the protection box 4. An extension cover 401 is fixedly installed on the front of the protection box 4, and an aeration pipe 402 is fixedly installed on the inner wall of the extension cover 401. The protection box 4 can provide an installation position for the surrounding components, and during installation, the protection box 4 can be embedded in the wall of the building, so as to fix the device. The extension cover 401 can 4, thereby improving the protection range of the device for the detection ball head 202, and guiding the air ejected from the aeration pipe 402 through the extension cover 401, so that the air ejected from the aeration pipe 402 forms an air curtain to protect the detection ball head 202, improving the effect of the detection ball head 202 on the sedimentation observation, and the aeration pipe 402 can guide the air pumped into the air pump 403, thereby forming an air curtain in front of the protection box 4, protecting the detection ball head 202, and preventing the surface of the detection ball head 202 from being contaminated with dust and water vapor to affect the detection effect; A sleeve 1 is fixedly installed on the back of the protection box 4, and a limit cylinder 103 is fixedly installed on the front end of the sleeve 1 to the inside of the protection box 4. The limit cylinder 103 is provided with slots on both the upper and lower sides. The sleeve 1 can provide a mounting position for the telescopic rod 2, and can store the telescopic rod 2 inside the sleeve 1, so as to avoid the detection ball head 202 extending out of the protection box 4 when not working and causing damage. The limit cylinder 103 can limit the side of the telescopic rod 2, thereby improving the stability of the telescopic rod 2, and avoiding irregular shaking of the telescopic rod 2 when working, thereby ensuring the accuracy of the detection ball head 202 in observing the settlement; A telescopic rod 2 is movably installed inside the sleeve 1, and a limiting cylinder 103 extends from the front end of the telescopic rod 2. The telescopic rod 2 can slide inside the sleeve 1 to adjust the installation position of the detection ball head 202, and the detection ball head 202 is fixed so that the detection ball head 202 can be observed at a fixed position for settlement; An inner cylinder 3 is fixedly installed inside the protection box 4. The inner cylinder 3 is a hollow cylindrical structure. A guide groove 301 is opened on the inner wall of the inner cylinder 3. Two brackets 303 are installed on the inner side of the inner cylinder 3. The bracket 303 is a triangular structure. Two groups of motors are fixedly installed on the bracket 303 near the position of the inner cylinder 3. A driving wheel 304 is fixedly installed on the output end of the motor, and the driving wheel 304 is engaged with the guide groove 301. A correction groove 302 is fixedly installed on the side of the bracket 303 near the center of the inner cylinder 3. The correction groove 302 is a semicircular structure, and rollers are evenly spaced on the inner wall of the correction groove 302. The inner cylinder 3 can provide an installation position for the internal components, and the guide groove 301 can limit the driving wheel 304. Then the limiting wheel is made to rotate at a uniform speed along the guide groove 301, and the bracket 303 can support the correcting groove 302, so that the correcting groove 302 applies a thrust to one side of the telescopic rod 2. The two correcting grooves 302 cooperate to limit the telescopic rod 2, and when the telescopic rod 2 deviates, the telescopic rod 2 drives the detection ball head 202 to reset, thereby ensuring the accuracy of the detection ball head 202 for settlement observation. The motor adopts YE3-100KW type. After the motor is powered on, it can rotate, thereby driving the driving wheel 304 to rotate. After the driving wheel 304 rotates, it applies a thrust to the bracket 303, so that the bracket 303 rotates around the telescopic rod 2, thereby driving the correcting groove 302 to rotate around the telescopic rod 2.

[0018] Furthermore, a spring 101 is fixedly installed inside the sleeve 1 near the rear end, and a baffle 102 is fixedly installed at the front end of the spring 101, and the baffle 102 is in contact with the inner wall of the sleeve 1. The spring 101 can apply elastic force to the baffle 102, and then when the baffle 102 collides with the telescopic rod 2, the telescopic rod 2 can be buffered by the elastic force applied to the baffle 102, so as to prevent the telescopic rod 2 from transmitting vibration to the detection ball head 202 and damaging the structure of the detection ball head 202, so as to ensure the durability and structural stability of the detection ball head 202.

[0019] Furthermore, spring pieces 201 are installed on the upper and lower sides of the telescopic rod 2 through pins and return springs. The spring pieces 201 are wedge-shaped structures, and the spring pieces 201 are consistent with the slots on the upper and lower sides of the limiting tube 103. A detection ball head 202 is fixedly installed on the front end of the telescopic rod 2. The spring piece 201 can pop out from the inside of the telescopic rod 2, and then after being engaged with the limiting tube 103, the telescopic rod 2 is limited, and the two correction grooves 302 are cooperated to wrap the telescopic rod 2 for rotation, so as to achieve stability and correction of the telescopic rod 2, and ensure that the detection ball head 202 can work in a fixed position, thereby improving the accuracy of the device for settlement observation. The detection ball head 202 can monitor the deviation amplitude of the observation point during the settlement process by photographing the observed object, and obtain the settlement degree of the measured object, so as to achieve settlement observation of the measured object and provide effective data for the settlement assessment of the building.

[0020] Furthermore, a controller 305 is installed on the outside of the inner tube 3, and the controller 305 is fixedly connected to the inner wall of the protection box 4. The controller 305 can be connected to other electronic components through wires, thereby controlling the various components inside the device to cooperate with each other and store the observation data, so that the staff can evaluate the settlement amplitude of the object under test according to the detection data.

[0021] Furthermore, an air pump 403 is fixedly installed on one side of the aeration pipe 402, and the air pump 403 is fixedly connected to the inner wall of the protection box 4. The air pump 403 is of CM-15W-6 type. After the air pump 403 is powered on, it can pump air into the inside of the aeration pipe 402, and then the air is ejected through the aeration pipe 402, forming an air curtain in front of the protection box 4 to protect the detection ball head 202.

[0022] Furthermore, reinforcing beams are installed on both sides of the bracket 303 by bolts, and the two ends of the reinforcing beams are fixedly connected to the two groups of brackets 303 respectively. The reinforcing beams fixedly connect the two brackets 303 to ensure the structural stability between the brackets 303, thereby improving the supporting effect and correcting effect of the bracket 303 and the correcting groove 302 on the telescopic rod 2.

[0023] Working principle: After the device is installed and confirmed to be correct, the telescopic rod 2 is pulled out from the sleeve 1, and the telescopic rod 2 and the limit tube 103 are fixed by the spring piece 201, and the correction groove 302 is supported by the bracket 303, and the bracket 303 with the correction groove 302 is respectively installed on the upper and lower sides of the telescopic rod 2, and the bracket 303 is installed in the guide groove 301 inside the inner tube 3 by installing the reinforcement beam, and the driving wheel 304 is driven to rotate by the motor, and the driving wheel 304 drives the bracket 303 to move, so that the bracket 303 and the correction groove 302 rotate at a uniform speed around the telescopic rod 2, and the correction groove 302 is used to contact the telescopic rod through a plurality of rollers on the inner side. 2 applies thrust to keep the telescopic rod 2 at the center of the inner cylinder 3, and the telescopic rod 2 fixes the detection ball head 202, so that the detection ball head 202 observes the settlement of the object to be measured. When the telescopic rod 2 is deformed, the two correction grooves 302 continue to apply lateral thrust to the telescopic rod 2, so that the telescopic rod 2 drives the detection ball head 202 to return to its original position. At the same time, the air pump 403 pumps air into the aeration pipe 402. The air sprayed from the aeration pipe 402 is guided by the extension cover 401 to form an air curtain in front of the protection box 4, so as to blow away the dust and water vapor in front of the device, so as to keep the space between the detection ball head 202 and the object to be measured clean, thereby ensuring the settlement observation effect of the detection ball head 202.
