Description

Technical Field

[0001] This invention relates to the field of inclinometer technology, and more specifically, to a method for deploying and retracting an inclinometer for slopes. Background Technology

[0002] Inclinometers are commonly used to detect lateral displacement of soil in landslide areas and deep excavation sites. They are also used to detect deformation of structures such as dams, or to detect settlement of the base of large buildings using horizontally embedded inclinometer tubes. The basic configuration of an inclinometer includes an inclinometer sleeve, an inclinometer probe, a control cable, and an inclinometer reading device. During use, the inclinometer probe is inserted into the inclinometer tube buried in the ground via the control cable. The cable is then pulled upwards, and the inclination angle of the inclinometer tube axis relative to the reference axis is measured at approximately the same interval, according to the markings on the cable, until the tube opening is reached.

[0003] When using inclinometers on slopes, the complex slope environment and the large amount of dust and impurities at the construction site often cause a large amount of dust and impurities to adhere to the surface of the inclinometer's control cable. This not only makes it difficult to store the control cable, but also makes it easy for the impurities and dust on the surface of the control cable to affect the working efficiency of the inclinometer the next time it is used. In severe cases, it may even lead to damage to the control cable and thus affect the surveying results. Summary of the Invention

[0004] This invention provides a method for deploying and retracting an inclinometer for slope protection, which solves the technical problem of a large amount of dust and impurities adhering to the surface of the inclinometer cable, thus affecting the working efficiency of the inclinometer.

[0005] To achieve the above objectives, the present invention provides a method for deploying and retrieving an inclinometer for slope protection, the method comprising:

[0006] S1. One end of the control cable is connected to the inclinometer probe, and the other end is connected to the inclinometer reading recorder;

[0007] S2. Adjust the support at the bottom of the inclinometer;

[0008] S3. Rotate the manual winder in the first rotation direction to release the control cable and place the inclinometer probe into the bottom of the inclinometer tube;

[0009] S4. Rotate the manual winder in the second rotation direction to retract the control cable. Take a measurement and record the data at equal intervals until the inclinometer probe is removed from the inclinometer tube. Clean the surface of the control cable while retracting it.

[0010] By employing the aforementioned technical solutions, when using an inclinometer to measure data, dust often adheres to the surface of the control cable. When the control cable is wound and placed inside the housing, the dust increases the frictional resistance of the cable, accelerating its wear. Alternatively, during the retrieval or placement process within the inclinometer tube, sand and gravel may embed into the insulation layer of the control cable, damaging the internal core wires and causing measurement errors. Therefore, this application designs a method for retrieving and placing an inclinometer for slope protection. During the control cable retrieval process, firstly, sand and gravel embedded in the wire insulation layer are cleaned, and then the dust adhering to the surface of the control cable is cleaned. This prevents dust and gravel from increasing wear on the control cable and helps extend the service life of the inclinometer.

[0011] Furthermore, during the recovery of the control cable, the inner rings of the two crescent-shaped supports adhere to the surface of the control cable.

[0012] By adopting the above technical solution, during the process of recycling the control cable, since the inner ring of the control cable is always in contact with the surface of the control cable, the inner ring of the crescent-shaped support can scrape off the sand embedded in the insulation layer of the control cable, preventing the sand from scratching the insulation layer of the control cable, affecting the internal core wire, and thus affecting the measurement results.

[0013] Furthermore, when the variable diameter section of the control cable passes through the crescent-shaped support, the surface of the variable diameter section is always in contact with the inner ring of the crescent-shaped support by the first telescopic device.

[0014] By adopting the above technical solution, the crescent-shaped support can clean the sand and gravel adhering to the surface of the control cable, preventing the sand and gravel from entering the interior. In addition, when the diameter of the control cable increases, the two crescent-shaped support parts are compressed. Because the first telescopic device keeps the surface of the diameter-changing section in contact with the inner ring of the crescent-shaped support part, the crescent-shaped support part can also be used to clean the sand and gravel on the surface of the insulation layer of the control cable, thus extending the service life of the equipment.

[0015] Furthermore, the method for cleaning the surface of the control cable also includes: the recovered control cable enters the cleaning equipment, the drive wheel is started, the drive wheel drives the driven wheel to move, and during the process of the control cable being collected, the brush on the belt cleans the surface of the control cable.

[0016] By adopting the above technical solution, the drive unit drives the cleaning equipment to work. A gap is left between the cleaning equipment and the control cable is within this gap. The brush on the belt cleans the dust on the surface of the control cable to prevent the presence of dust from causing the device to malfunction, thereby improving the working efficiency of the device.

[0017] Furthermore, the method for cleaning the surface of the control cable also includes: when the variable diameter section control cable passes through the cleaning device, the second telescopic device ensures that the variable diameter section control cable always fits against the first mounting plate and the second mounting plate, and the cleaning device cleans the dust on the surface of the variable diameter section control cable.

[0018] By adopting the above technical solution, when the diameter of the control cable increases, the variable-diameter section of the control cable is compressed, increasing the distance between the first and second mounting plates on both sides of the variable-diameter section. Then, the brush on the belt cleans the surface of the variable-diameter section of the control cable of dust. Conversely, when the diameter of the control cable decreases, the control cable can pass directly through the crescent-shaped support. In this case, the crescent-shaped support cannot effectively clean the sand and gravel on the insulation layer of the control cable. Then, the recovered control cable enters the cleaning equipment, where the brush on the belt cleans the dust and sand from the control cable, preventing damage to the device from dust and sand.

[0019] Furthermore, during the process of recycling the control cable, the brush is cleaned by the following method: the drive motor drives the cleaning wheel; when the brush comes into contact with the cleaning wheel, the cleaning wheel causes the brush to bend backward; when the bent brush has completely passed the cleaning wheel, the brush rebounds, and the rebound vibration causes the dust attached to the brush to fall off.

[0020] By adopting the above technical solution, the brush on the belt is used to clean the control cable. Some of the dust on the control cable will fall into the storage box, while the rest will stick to the brush. When the brush comes into contact with the cleaning wheel, the elasticity of the brush itself causes the brush to bend backward. When the bent brush has completely passed the cleaning wheel, the brush rebounds, and the vibration of the rebound causes the dust attached to the brush to fall off.

[0021] Furthermore, during the cleaning of the control cable surface, on the contact surface between the belt and the control cable, the belt and the control cable are in opposite directions of transport.

[0022] By adopting the above technical solution, the conveyor belt and the control cable are transported in opposite directions, which helps to improve the dust removal efficiency of the brush on the surface of the control cable.

[0023] Furthermore, during the cleaning process, on the contact surface between the belt and the cleaning wheel, the belt and the cleaning wheel are in opposite directions of transport.

[0024] By adopting the above technical solution, the conveying direction of the belt and the cleaning wheel is opposite, which helps to improve the efficiency of dust removal by the brush.

[0025] Furthermore, during the process of controlling cable retrieval or release, the retrieval or release of the control cable is guided by a conductor mechanism.

[0026] By adopting the above technical solution, we can prevent the control cable from getting stuck inside during the retrieval or release process, thus avoiding interference with the normal operation of the measurement work.

[0027] Furthermore, during the process of cleaning the dust on the surface of the control cables and the dust adhering to the brush, the cleaned dust falls into the receiving box.

[0028] By adopting the above technical solution, the container is used to hold the dust that is being cleaned.

[0029] This invention provides a method for deploying and retracting an inclinometer for slope protection, which has at least the following technical advantages:

[0030] 1. During the recovery of the control cable, the inner rings of the two crescent-shaped supports are attached to the surface of the control cable. This allows the inner rings of the crescent-shaped supports to scrape away the sand embedded in the insulation layer of the control cable, preventing the sand from scratching the insulation layer of the control cable, affecting the internal core wires, and thus affecting the measurement results.

[0031] 2. Another method for cleaning the surface of control cables includes: the recovered control cables enter the cleaning equipment, the drive wheel is activated, and the drive wheel drives the driven wheel. During the cable recovery process, brushes on the belt clean the surface of the control cables. This method utilizes the brushes on the belt to clean dust from the surface of the control cables, preventing dust from causing device malfunctions and thus improving the device's working efficiency.
