[0002] In the field of engineering construction, deep foundation pit engineering is considered one of the most dangerous and complex projects. Due to the extremely complex geological conditions, related accidents occur frequently. Therefore, monitoring should be carried out during construction to ensure the safety of the construction environment and surrounding environment, and to avoid accidents such as foundation pit collapse. An inclinometer is an instrument used to measure the apex angle and azimuth angle of engineering structures such as boreholes, foundation pits, foundations, walls, and dam slopes.

[0003] Currently, most inclinometers on the market still use the traditional method of manually pulling the probe cable. When the inclinometer tube being inspected is deep and the number of tubes being inspected is large, the labor intensity of the operators is extremely high. To alleviate the labor intensity, two people usually take turns working, which increases labor costs. In addition, the long-term repetitive, high-intensity, and low-skill measurement operation makes young technicians prone to resistance, resulting in poor stability of the technical team on the construction site.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] Figure 1 A schematic diagram of the portable inclinometer device of this invention is shown. Figure 2 The front view of the portable inclinometer device of this invention is shown. Figure 3 yes Figure 2 Enlarged view of point A in the image. Figure 4The diagram shows a front view of the start / stop unit in this invention. The inclinometer device includes a base 1 and an inclinometer mechanism 2 mounted on the base 1. The inclinometer mechanism 2 includes an inclinometer probe 4, a cable 21 connected to the inclinometer probe 4, a cable reel 22, a driven pulley 23, and a start / stop unit 24 mounted on the driven pulley 23. The fixed end of the cable 21 is wound around the cable reel 22, the middle section of the cable 21 is distributed along the upper surface of the driven pulley 23, and the start / stop unit 24 abuts against the surface of the cable 21. A drive motor 25 is located at the center of the cable reel 22. The cable reel 22 is sleeved on the output end of the drive motor 23, so that when the drive motor 23 outputs power, it can drive the cable reel 22 to rotate. The drive motor 25 is signal connected to the start / stop unit 24. The cable reel 22 rotates under the drive of the drive motor 23. The cable reel 22 drives the cable 21 to move on the surface of the driven pulley 23 to change its measurement length, thereby enabling the inclination probe 4 to perform inclination measurement at different positions.In this embodiment, the cable reel 22 is used to accommodate the cable 21, winding the cable 21 to store a sufficient length of cable 21 in a small space. The start / stop unit 24 is used to control the rotation direction of the output end of the drive motor 25, thereby controlling the rotation direction of the cable reel so that the inclinometer probe 4 on the cable 21 rises or falls at the corresponding position. That is, when the start / stop unit 24 generates and sends a first electrical signal to the drive motor 25, and the drive motor 25 outputs power, the cable reel 22 rotates in the forward direction. The cable reel 22 is also driven in the forward direction by the drive motor 25, so that the cable 21 is gradually released from the cable reel 22 and moves along the surface of the driven pulley 23, extending the measurement length of the cable 21, so that the inclinometer probe 4 can descend along the slope on the corresponding slope, and the inclinometer probe 4 can then perform inclinometer measurement at a deeper position. Similarly, when the start / stop unit 24 generates and sends a second electrical signal to the drive motor 25, the cable reel 22 rotates in the forward direction. When the drive motor 25 outputs power, the cable reel 22 rotates in the reverse direction. Driven by the drive motor 25, the cable reel 22 also rotates in the reverse direction and moves along the surface of the driven pulley 23, causing the cable 21 to wind up along the surface of the cable reel 22. This allows the inclinometer probe 4 to rise along the corresponding incline, and the inclinometer probe 44 can then perform inclinometer measurements at a shallower position. That is, by using the motor to drive the cable reel 22, the rotation of the cable reel 22 drives the cable to move on the surface of the driven pulley, and the cable rises or falls along the corresponding incline, changing the position of the cable on the incline. This drives the inclinometer probe 4 on the cable detection end to move along the incline and change the position of the inclinometer probe 4, allowing the inclinometer probe 4 to perform inclinometer measurements at different positions. Using the start / stop unit 24 and the drive motor 25 to control the movement of the cable saves technicians a lot of repetitive physical labor, allowing technicians to concentrate on checking and verifying the inclinometer results, improving the technicians' enthusiasm for inclinometer work and the stability of the inclinometer results.

[0031] It should be noted that the inclinometer probe 4 is electrically connected to the corresponding cable, enabling it to transmit signals or data. The inclinometer probe 4 typically contains two mutually perpendicular accelerometers, corresponding to the two axes of the inclinometer guide groove within the probe 4. When the probe slides within the corresponding shaft or inclined plane, the accelerometers sense changes in the direction of gravity in real time. The inclinometer probe 4 then transmits the data to the reading instrument via the cable, and the software automatically calculates the displacement and generates a curve.

[0032] Furthermore, the driven pulley 23 is provided with two pulley protective covers 231 symmetrically distributed around the center of the pulley. A space is left between the two pulley protective covers 231 and the driven pulley 23 to accommodate the cable 21 and allow it to move. The two pulley protective covers 231 are symmetrically distributed based on the centerline of the driven pulley 23 in the vertical direction. The shape of the pulley protective covers 231 is arc-shaped, and its curvature matches the outer edge curvature of the driven pulley 23, allowing them to fit snugly against both sides of the driven pulley 23. This prevents external debris, dust, etc., from entering between the pulley and the cable 21, avoiding wear or jamming of the cable 21, and preventing accidental contact between personnel or other objects and the rotating pulley. This helps extend the service life of the inclinometer device and enhances safety protection during operation.

[0033] Furthermore, the start / stop unit 24 is located between the two pulley protective covers 231, and both ends of the start / stop unit 24 extend to form arc-shaped connecting rods 26. The start / stop unit 24 is connected to the two pulley protective covers 231 respectively based on the arc-shaped connecting rods 26. In this embodiment, the start / stop unit 24 is located between the two pulley protective covers 231, making full use of the space between the pulley protective covers 231, making the structure of the entire device more compact, avoiding the external placement of the start / stop unit 24, improving the space utilization rate of the inclinometer device, and allowing the operator to clearly see the contact relationship between the driven pulley 23, the cable 21, and the start / stop unit 24 from the position of the start / stop unit 24, which is beneficial for the operator to directly and clearly see the fault location when a fault occurs. Secondly, the start-stop unit 24 is connected to the pulley protection cover 231 through two arc-shaped connecting rods 26. The connection method is simple and reliable, and can withstand the vibration and impact generated by the start-stop unit 24 during operation. When subjected to external force, the arc-shaped connecting rods 26 can distribute the stress to the entire arc segment, reduce the stress on the connection point, and make the internal stress distribution more uniform, thereby greatly improving the strength and reliability of the connection and ensuring the stability of the connection.

[0034] Furthermore, the start / stop unit 24 includes: a connecting seat 241, a rotating rod 242, and a return spring 243; the rotating rod 242 is rotatably mounted on the connecting seat 241 based on a pin, and the rotating rod 242 includes: an L-shaped rod 2421 and an arc-shaped rod 2422, the L-shaped rod 2421 and the arc-shaped rod 2422 are integrally formed, and one end of the return spring 243 is connected to the middle of the L-shaped rod 2421, and the other end of the return spring 243 is connected to the connecting seat 241. In this embodiment, both ends of the connecting seat 241 are fixedly connected to corresponding arc-shaped connectors to ensure that the connecting seat 241 is fixed between the two pulley protective covers 231. The rotating rod is used to automatically press the corresponding button to make the drive motor 25 work. The return spring 243 is used to reset the rotating rod. When the rotating rod is rotated under force, the return spring 243 is stretched under force and has a reaction force on the rotating rod, so that the rotating rod is reset, providing sufficient elasticity to make the rotating rod quickly reset after operation. The rotating rod is rotatably mounted on the connecting seat 241. The position of the rotating rod can be adjusted according to the start and stop control requirements of different devices to adapt to cables 21 of different radii, so as to improve the versatility of the inclinometer device.

[0035] Furthermore, a movable roller 2423 is provided at the end of the arc-shaped rod 2422, and the surface of the movable roller 2423 abuts against the cable 21. The cable 21 is driven by the cable reel 22 to move along the surface of the movable roller 2423, causing the rotating rod to swing. Since the surface of the cable 21 is provided with corresponding protruding marks 211, when the cable 21 moves along the surface of the movable roller 2423, the protruding marks 211 push up the movable roller 2423, causing the movable roller to drive the rotating rod to swing. That is, when the movable roller 2423 moves from the surface of the cable 21 to the surface of the protruding marks 211, it drives the rotating rod to move in the opposite direction; when the movable roller 2423 moves from the protruding marks 211 to the surface of the cable 21, it drives the rotating rod to move in the forward direction. In this embodiment, the surface of the movable roller 2423 abuts against the cable 21. When the cable 21 is driven by the cable reel 22 to move along the driven roller, the movable roller 2423 can abut against the protruding mark 211 along the surface of the cable 21. Since the protruding mark 211 is slightly higher than the surface of the cable 21, when the movable roller 2423 moves from the surface of the cable 21 to the surface of the protruding mark 211, the movable roller 2423 drives the rotating rod to move in the opposite direction, thereby causing the return spring 243 to be stretched. The return spring 243 has a reaction force on the rotating rod, causing the rotating rod to have a tendency to move in the forward direction, thereby ensuring that the movable roller 2423 is in contact with the surface of the cable 21. When the moving roller 2423 moves from the surface of the raised mark 211 to the surface of the cable 21, since the surface of the cable 21 is slightly lower than the raised mark 211, the moving roller 2423 drives the rotating rod to move forward. At the same time, the return spring 243 returns to its original shape and pulls the pulling rod, so that the rotating rod can fit against the surface of the cable 21, which can accurately identify each raised mark 211 and improve measurement accuracy.

[0036] Furthermore, the start / stop unit 24 is also provided with a latch 244. The latch 244 is located on the side of the rotating rod away from the return spring 243, and the latch 244 engages with the connection between the L-shaped rod 2421 and the arc-shaped rod 2422. The latch 244 is used to limit the rotation range of the rotating rod. When the rotating rod 242 rotates to a specified angle, the latch 244 abuts against the connection between the L-shaped rod 2421 and the arc-shaped rod 2422, so that the rotating rod can only rotate a small range. This avoids the situation where the rotating rod rotates a large range, exceeding the elastic range of the return spring 243, or rotating a large range due to accidental contact, external impact, or improper operation. This helps the return spring 243 to stably perform its function within its elastic range, ensuring that the rotating rod can accurately return to its original position after operation, and guaranteeing the normal operation of the equipment's start / stop function.

[0037] Furthermore, the start / stop unit 24 is also equipped with a lowering switch 245 and an uppering switch 246. The uppering switch 246 is installed at the end of the connecting seat 241 away from the latch 244, and the lowering switch 245 is installed at the other end of the connecting seat 241 near the latch 244. The uppering switch 246 abuts against the end of the L-shaped rod 2421. In this embodiment, the uppering switch 246 controls the drive motor 25 to rotate in the opposite direction, thereby causing the cable reel 22 to rotate in the opposite direction. Consequently, the cable 21 is wound around the surface of the cable reel 22, and the cable 21 moves along the surface of the driven pulley 23 under the force of the cable reel 22. Finally, the inclinometer probe 4 moves upward along the incline to achieve ascent. Conversely, the descent switch 245 controls the drive motor 25 to rotate in the forward direction, which in turn causes the cable reel 22 to rotate in the forward direction. Consequently, the cable 21 is released along the cable reel 22, and the cable 21 moves along the surface of the driven pulley 23 under the force of the cable reel 22. Finally, the inclinometer probe 4 moves downward along the incline to achieve descent. This allows the switch device to accurately identify the rope-raising pause position and automatically shut off during inclinometer work, eliminating the need for manual identification, saving the effort of surveying technicians, and also eliminating the influence of human identification deviation. The measurement results are more stable and the measurement accuracy is higher.

[0038] It should be noted that the rising switch 246 has two buttons, one of which abuts against the end of the L-shaped rod 2421. The two buttons form a double-control switch, meaning that pressing either button will also connect the circuit, thereby controlling the drive motor 25. The button abutting against the end of the L-shaped rod 2421 can be pressed by the L-shaped rod 2421 according to the protrusion marking 211 on the cable 21. The other button can be pressed manually by the operator according to the usage situation to adapt to various usage scenarios. The falling switch 245, on the other hand, has only one button and is manually controlled by the operator.

[0039] Furthermore, the base 1 is provided with a pulley bracket 11 and a reel bracket 12. The driven pulley 23 is mounted on the base 1 based on the pulley bracket 11, and the cable reel 22 is mounted on the base 1 based on the reel bracket 12. A support rod 13 is provided between the pulley bracket 11 and the reel bracket 12, with one end of the support rod 13 connected to the pulley bracket 11 and the other end connected to the reel bracket 12. In this embodiment, the pulley bracket 11 supports the driven pulley 23, and the reel bracket 12 ultimately supports the cable reel 22. The support connection enhances the structural stability between the pulley bracket 11 and the reel bracket 12, preventing them from shaking or deforming during the cable 21 winding and unwinding process, thus improving the structural stability of the inclinometer device.

[0040] Furthermore, a battery compartment 3 containing batteries is provided on the support rod 13, and the battery compartment 3 is electrically connected to the inclinometer mechanism 2. In this embodiment, the battery compartment 3 is used to hold batteries, and the electrical energy in the batteries is transmitted to the inclinometer mechanism 2 through wires, ensuring that the inclinometer mechanism 2 has sufficient electrical energy to support its operation. This avoids the need to find a power source and lay power lines on-site, reducing the influence of on-site power supply and preventing the inclinometer device from being positioned unfavorably for measurement. It also helps to place the inclinometer device in the most suitable measurement position, thereby improving the efficiency of inclinometer work. Secondly, the batteries in the battery compartment 3 are detachably installed in the battery compartment 3. When the batteries in the battery compartment 3 are depleted, new batteries can be directly replaced with the batteries that are currently in use, ensuring that the batteries can be replaced quickly to restore the operation of the inclinometer equipment.

[0041] Furthermore, a handle 31 is provided on the upper surface of the battery compartment 3. The handle 31 on the upper surface of the battery compartment 3 avoids difficulties in gripping due to the smooth surface or irregular shape of the battery compartment 3, allowing users to move the battery compartment 3 or replace the battery without directly contacting other parts of the battery compartment 3. During operation, the handle 31 provides a stable gripping point, reducing the risk of the battery compartment 3 falling due to slippage or improper operation, thereby protecting the safety of the battery and the device.

[0042] In summary, this utility model incorporates a start / stop unit and a drive motor in a portable inclinometer. The start / stop unit controls the drive motor to drive a cable reel, which rotates to move the cable along the surface of a driven pulley. This causes the cable to rise or fall along the corresponding incline, changing its position on the incline. This, in turn, moves the inclinometer probe on the cable's detection end along the incline, changing its position and allowing the probe to measure inclines from different locations. Using the start / stop unit and drive motor to control the cable movement saves technicians a significant amount of repetitive physical labor, allowing them to focus on checking and verifying the inclinometer results. This improves the technicians' enthusiasm for inclinometer work and the stability of the results.

Specific examples have been used to illustrate the principles and implementation methods of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
