[0002] Geological disasters are natural disasters mainly caused by abnormal changes in the geological environment. To avoid geological disasters, depth detectors are often used to detect the depth of cracks in space. The depth detector can detect the depth of cracks through ultrasonic waves, thus facilitating subsequent repair of the cracks. When detecting the depth of cracks at the top of the space, due to the high height of the space, it is inconvenient for the staff to hold the depth detector to detect the depth of the cracks at the top of the space, which affects the work efficiency of the staff.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0022] Reference Figures 1 to 3 As shown, the utility model provides a geological disaster depth detector, including a base 1, a column 2 is connected to the top of the base 1, a slider 5 is slidably connected to the column 2, a bracket 3 is connected to the top of the column 2, a screw rod 4 is rotatably connected between the bracket 3 and the base 1, the slider 5 is threadedly connected to the screw rod 4, a driving component is transmission-connected to the screw rod 4, a side of the slider 5 away from the column 2 is connected to a cross plate 11, an electric push rod 12 is installed on the cross plate 11, the telescopic end of the electric push rod 12 is connected to a fixed plate 13, and a clamping component for fixing a depth detector body 24 is provided on the fixed plate 13.

[0023] The set clamping component can stably fix the depth detector body 24 and is convenient for disassembly and storage. By setting the driving component to drive the screw rod 4 to rotate, and at the same time, the sliding limit of the slider 5 on the column 2 and the threaded connection between the slider 5 and the screw rod 4 work together, the slider 5 drives the fixed plate 13 and the electric push rod 12 to move up and down. By setting the telescopic electric push rod 12, the height of the depth detector body 24 is further finely adjusted and the top of the geological space to be detected is contacted by the depth detector body 24, improving the detection accuracy.

[0024] The utility model is easy to operate, can replace manual hand-held detectors to detect the crack depth of the space top, and improves the detection efficiency.

[0025] Further, the driving component includes a motor 7 fixedly installed on the base 1. The output end of the motor 7 is connected with a driving pulley 8. One end of the screw rod 4 close to the base 1 is connected with a driven pulley 6. The diameter of the driving pulley 8 is smaller than that of the driven pulley 6. The driving pulley 8 is in transmission cooperation with the driven pulley 6 through a belt.

[0026] By setting the motor 7 to drive the driving pulley 8 to rotate, through the rotation of the belt, the driving pulley 8 drives the driven pulley 6 to rotate, and the rotation of the driven pulley 6 drives the screw rod 4 to rotate.

[0027] Further, the column 2 is an I-beam. One end of the slider 5 is provided with a groove 9. The groove 9 is of a C-shaped structure. The slider 5 is slidably connected to the column 2 through the groove 9.

[0028] Further, in order to reduce the friction between the slider 5 and the column 2 and improve the stability of the slider 5 during movement, rollers 10 are rotatably connected to the opposite side walls of the groove 9 and the column 2. The rollers 10 are in sliding contact with the column 2.

[0029] Further, the clamping component includes a positioning frame 14 fixedly connected to the top end of the fixed plate 13. The cross-section of the positioning frame 14 is of an annular structure. A guide rod 17 is fixedly connected to the lower part of the positioning frame 14 in the horizontal direction. A bidirectional threaded rod 15 is rotatably connected to the upper part of the positioning frame 14 in the horizontal direction. One end of the bidirectional threaded rod 15 penetrates through the side wall of the positioning frame 14 and is fixedly connected with a handle 16. Both ends of the bidirectional threaded rod 15 are threadedly connected with clamping plates 18. The bottom ends of the two clamping plates 18 are slidably sleeved on the guide rod 17, and the two clamping plates 18 are symmetrically arranged on both sides of the depth detector body 24 respectively.

[0030] By rotating the handle 16 to drive the bidirectional threaded rod 15 to rotate, the two clamping plates 18 approach the depth detector body 24 synchronously under the joint action of the bidirectional threaded rod 15 and the guide rod 17 and are pressed against the depth detector body 24, thereby realizing the fixation of the depth detector body 24.

[0031] Furthermore, in order to prevent damage caused by direct contact between the depth detector body 24 and the geology during the ascending process, a support rod 19 is fixedly connected to the top end of the fixing plate 13. The top end of the support rod 19 is fixedly connected to an annular plate 20. The annular plate 20 is sleeved on the depth detector body 24, and there is a gap between the annular plate 20 and the depth detector body 24. The detection end of the depth detector body 24 is lower than the top end of the annular plate 20.

[0032] Furthermore, an annular elastic block 21 is fixedly connected to the top end of the annular plate 20. The annular elastic block 21 is coaxially arranged with the annular plate 20. A travel switch 22 is arranged at the top end of the annular plate 20. The height of the travel switch 22 is lower than the thickness of the annular elastic block 21. The travel switch 22 is electrically connected to a microcontroller. The electric push rod 12 and the driving assembly are both electrically connected to the microcontroller.

[0033] During the ascending of the slider 5 or the elongation of the electric push rod 12, in order to prevent the annular plate 20 from being squeezed and deformed after contacting the geology, thereby damaging the depth detector body 24, the annular elastic block 21 first contacts the geology surface and is gradually compressed. When the travel switch 22 is triggered, the travel switch 22 transmits a signal to the microcontroller, and the microcontroller controls the motor 7 and the electric push rod 12 to stop running.

[0034] Furthermore, in order to facilitate observing the crack conditions at the top of the geological space and the surrounding working environment, a camera 23 is installed at the top end of the fixing plate 13.

[0035] The working principle of the geological disaster depth detector provided by the present utility model: When in use, place the depth detector body 24 in the middle of the positioning frame 14. At the same time, rotate the handle 16 to drive the bidirectional threaded rod 15 to rotate. Under the combined action of the bidirectional threaded rod 15 and the guide rod 17, the two clamping plates 18 move synchronously closer to the depth detector body 24 and press tightly on the depth detector body 24, thereby realizing the fixation of the depth detector body 24. Start the motor 7. The motor 7 drives the driving pulley 8 to rotate. Through the rotation of the belt, the driving pulley 8 drives the driven pulley 6 to rotate. The rotation of the driven pulley 6 drives the lead screw 4 to rotate. At the same time, under the combined action of the sliding limit of the slider 5 on the column 2 and the threaded connection between the slider 5 and the lead screw 4, the slider 5 drives the fixing plate 13 and the electric push rod 12 to rise. When it is observed that the depth detector body 24 is about 15 centimeters away from the crack at the top of the space, turn off the motor 7 and start the electric push rod 12 to elongate until the travel switch 22 is triggered and the electric push rod 12 stops running. Then start the depth detector body 24 to detect the depth of the crack at the top of the space.
