Description

Technical Field

[0001] This utility model relates to the field of monitoring equipment technology, specifically a deep displacement inclinometer for landslide monitoring. Background Technology

[0002] A deep displacement inclinometer is an important device for landslide monitoring. It typically consists of an inclinometer tube, a probe, and a data acquisition system. The inclinometer tube is buried in a borehole in the landslide body, and the probe is inserted into the inclinometer tube via a cable. The sensor inside the probe can measure the change in the probe's tilt angle within the inclinometer tube. When the landslide body displaces, the inclinometer tube deforms accordingly, and the tilt angle measured by the probe changes accordingly. By measuring and analyzing these angle changes, the horizontal displacement at different depths of the landslide body can be calculated.

[0003] Deep displacement inclinometers are classified into guide wheel inclinometers and fixed inclinometers according to their measurement methods. Guide wheel inclinometers require manual lifting and lowering of the probe rod to different depths to measure the tilt angle and calculate the displacement point by point. Fixed inclinometers, on the other hand, are permanently installed inside the inclinometer tube and measure the tilt angle change through a gravity accelerometer, supporting automated monitoring.

[0004] Existing guide wheel inclinometers can only acquire data from a single point at a time, relying heavily on manual operation and failing to achieve efficient automated monitoring. While guide wheel inclinometers equipped with Bluetooth for mobile phone control have solved the problem of automated monitoring, they still require manual lifting and lowering of the probe rod and do not integrate well with fixed inclinometers.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a deep displacement inclinometer for landslide monitoring, comprising a support frame and a probe rod. The outer wall of the support frame is equipped with multiple sets of sliders, and one end of each slider is equipped with a connecting rod. One end of the connecting rod is provided with a limit block, and the top of the limit block is provided with a positioning plate. One end of the positioning plate is equipped with a bearing, and a rotating rod is provided inside the bearing.

[0007] By adopting the above technical solution, the placement position of the probe of the guide wheel inclinometer can be changed through the setting of connecting rods and limiting blocks. This allows users to adjust the position of the device according to the actual situation. It can be placed at one end of the monitoring port or at the top of the monitoring port. The change in tilt angle is measured by gravity accelerometer, thereby achieving the effect of combining the guide wheel inclinometer with the fixed inclinometer, reducing monitoring costs and improving work efficiency. The setting of the locking block temporarily limits the probe, making it easier for users to move the device, thereby reducing the probability of probe collision, increasing the service life of the device, and also making it easier for users to move the device.

[0008] The present invention is further configured such that the electric push rod is installed on the top of the support frame, and a baffle is installed at one end of the electric push rod.

[0013] Preferably, the arrangement of the round hole and the through hole facilitates the connection between the round hole and the bolt to limit the position of the limiting block, and also facilitates the limiting of the connecting line.

[0014] The present invention is further configured such that the diameter of the circular hole is the same as that of the through hole, and the inner wall of the circular hole is provided with an internal thread.

[0015] Preferably, the engagement of the round hole and the bolt facilitates the positioning of the slider, and the position of the limit block can be adjusted according to the position of the monitoring port, thereby improving the practicality of the device.

[0016] The present invention is further configured such that the slider is sleeved on the outer wall of the support frame, and a connecting rod is installed at one end of each set of sliders.

[0017] Preferably, the slider is frame-shaped and fitted onto the outer wall of the support frame, and the connecting rod is located between the two sets of sliders, moving the two sets of sliders simultaneously.

[0018] The present invention is further configured such that a limiting block is fixedly installed at one end of the connecting rod, and the opening end of the limiting block is arc-shaped, and the two sets of limiting blocks are arranged opposite to each other.

[0019] Preferably, the relative movement of the limiting block facilitates the limiting of the probe rod and the connecting wires inside the device, thereby effectively protecting the probe rod and the connecting wires.

[0020] The present invention is further configured such that both ends of the fixing frame are equipped with locking blocks, and the locking blocks are in contact with the outer wall of the probe rod.

It can be placed at one end of the monitoring port or on top of the monitoring port. The tilt angle change is measured by a gravity accelerometer, thus achieving the combined effect of a guide wheel inclinometer and a fixed inclinometer, reducing monitoring costs and improving work efficiency. The locking block 5 temporarily limits the probe, facilitating user movement of the device, reducing the probability of probe collision, increasing the device's lifespan, and making it easier for the user to move the device.

[0029] For details regarding the above embodiments, please refer to [link / reference]. Figures 1-3 The electric push rod 43 is installed on the top of the support frame 1, and a baffle 2 is installed at one end of the electric push rod 43. The baffle 2 connects the support frame 1 and the fixed frame 3, making it easy for the user to pull the fixed frame 3 to move the device.

[0030] For details regarding the above embodiments, please refer to [link / reference]. Figures 1-3 A fixing frame 3 is provided at one end of the baffle 2, and the fixing frame 3 is connected to the support frame 1 and the baffle 2 by bolts. The baffle 2 protects the positioning plate 4, and the fixing frame 3 facilitates the movement of the device and improves the working efficiency of the device.

[0031] For details regarding the above embodiments, please refer to [link / reference]. Figures 1-3 The support frame 1 has multiple sets of round holes 10 at both ends, and the inner wall of the slider 11 has multiple sets of through holes 110. The round holes 10 and through holes 110 are arranged opposite each other to facilitate the connection of the round holes 10 with bolts to limit the position of the limiting block 13, and also to limit the connection line.

[0032] For details regarding the above embodiments, please refer to [link / reference]. Figures 1-3 The circular hole 10 and the through hole 110 have the same diameter, and the inner wall of the circular hole 10 is provided with internal threads. The circular hole 10 meshes with the bolt to facilitate the positioning of the slider 11. The position of the limit block 13 can be adjusted according to the position of the monitoring port, thereby improving the practicality of the device.

[0033] For details regarding the above embodiments, please refer to [link / reference].

[0034] For details regarding the above embodiments, please refer to [link / reference]. Figures 1-3 A limiting block 13 is fixedly installed at one end of the connecting rod 12, and the opening end of the limiting block 13 is arc-shaped.

[0035] Second embodiment: Please see Figure 3 , Figure 4 The difference between Embodiment 2 and Embodiment 1 is that, while retaining the features of Embodiment 1, a locking block 5 is added to both ends of the fixing frame 3 to facilitate temporary positioning of the locking block 5.

[0036] The locking block 5 is fixedly connected to the fixing frame 3, and one end of the opening of the locking block 5 is arc-shaped.

[0037] In practical operation, this utility model is as follows: When the equipment is needed to monitor landslides, first move the equipment to the appropriate location, then install the probe on the connecting line. The probe is placed in the monitoring port, and the user can lift and lower the probe to different depths to measure the tilt angle and calculate the displacement point by point. When the probe needs to be installed in the monitoring port for a long time, move the two sets of connecting rods 12 so that the two sets of limiting blocks 13 are relatively close. The limiting blocks 13 are provided with internal threads, and then bolts are passed through the through holes 110. The bolts engage with the inner wall of the limiting blocks 13 to limit the position of the limiting blocks 13. Finally, the electric push rod 43 is moved upward by the control button to make it easier for the probe to pass through the limiting blocks 13 and be placed in the monitoring port. This allows the device to measure the tilt angle change through the gravity accelerometer, and also protects the detection port. Furthermore, locking blocks 5 are installed at both ends of the fixing frame 3, and the open end of the locking block 5 is arc-shaped. The locking block 5 fits against the outer wall of the probe rod, which makes it easy to temporarily limit the position of the locking block 5, so that the user can easily adjust the device, avoid the probe rod being placed randomly, and reduce the possibility of the probe rod being hit.
