The driving protection component drives the multiple fitting covers 19 to move vertically, so that each fitting cover 19 covers and locks onto the two mounting blocks 1, forming a protective area outside the two mounting blocks 1. At the same time, the driving protection component drives the frame strip 5 to rotate, and the frame strip 5 drives the self-protecting adjustment component to surround the width measuring component, synchronously forming a protective area outside the width measuring component. During this period, the self-protecting adjustment component adaptively adjusts its own length according to the length of the width measuring component to achieve effective protection of the width measuring component.

[0030] In this embodiment, as Figure 1 - Figure 3 As shown, the width measurement component includes: a measuring rod 2, positioned between two mounting blocks 1; a measuring sleeve 3 slidably connected to the outer wall of the measuring rod 2; and a distance sensor 4 installed on one side of the inner wall of the measuring sleeve 3, used to measure the movement distance of the measuring rod 2.

[0034] In use, the speed reducer rudder 15 drives the drive shaft 14 to rotate counterclockwise, the drive shaft 14 drives the separation strip 16 to no longer contact the bottom end of the inclined strip 17, the attached cover 19 drives the linkage strip 20 to move downward, the linkage strip 20 drives the other attached cover 19 to move downward synchronously, the attached cover 19 drives the inclined strip 17 to move downward, and the plurality of inclined teeth 18 move downward, until the inner wall top surface of the attached cover 19 is attached with the upper surface of the mounting block 1, the two attached covers 19 form a protection area outside the two mounting blocks 1, synchronous protection driving is realized, and when the frame strip 5 rotates counterclockwise, the support strip 23 rotates counterclockwise synchronously, the inclined pressing strip 21 drives the plurality of pressing teeth 22 to rotate counterclockwise, the plurality of pressing teeth 22 are pressed on the right side of the inclined strip 17, the plurality of pressing teeth 22 are meshed and pressed with the inclined teeth 18, the plurality of inclined teeth 18 are pressed and locked, the plurality of inclined teeth 18 lock the inclined strip 17, and finally the inclined strip 17 locks the attached cover 19, which can protect outside the mounting block 1 and avoid non-professionals from disassembling and changing the position of the mounting block 1.

[0035] In this embodiment, as shown in Figure 7 The inner wall top end of the attached cover 19 and close to the position of the inclined strip 17 is provided with two guide rods 26 for sliding along the inner wall of the mounting block 1. By driving the two guide rods 26 to move downward by the attached cover 19, the guide rods 26 are guided to move downward along the inner wall of the mounting block 1, so as to ensure that the attached cover 19 moves vertically downward.

[0036] In this embodiment, as shown in Figure 7As shown, the lower part of the frame strip 5 is provided with a battery 24 and a wireless controller 25, the wireless controller 25 and the battery 24 are fixedly connected with the mounting block 1, and the battery 24 and the wireless controller 25 are electrically connected. The wireless controller 25 is powered by the battery 24, and the wireless controller 25 can start the speed reducer 15 to realize the transmission control of the speed reducer 15.

[0037] The working principle of the adjustable clamp type measuring device for monitoring slope surface cracks is as follows.

[0038] Firstly, when the clamp installation is adjusted, the mounting block 1 is pulled to the left, the mounting block 1 drives the measuring rod 2 to move, and the measuring rod 2 moves from the inside of the measuring sleeve 3, so that the distance between the measuring rod 2 and the distance sensor 4 is increased, and the distance between the two mounting blocks 1 is also increased. At the same time, the mounting block 1 drives the displacement shaft 6 to move to the left, the displacement shaft 6 drives the covering shell 8 to move to the left, the covering shell 8 moves to the left along the inside of the sleeve shell 9, and the mounting block 1 drives the fixed shell 10 to move to the left, the fixed shell 10 slides to the left along the outer wall of the sleeve shell 9, and the fixed shell 10 drives the plurality of protective teeth 11 to move to the left, while the other mounting block 1 supports the fixed sleeve 12, the fixed sleeve 12 supports the sleeve shell 9, keeps the sleeve shell 9 and the fixed sleeve 12 from moving, and the two mounting blocks 1 can adjust the measuring position, the two mounting blocks 1 are located on both sides of the slope surface crack, and the pre-buried bolt clamp is inserted into the hole position on the mounting block 1 to fix the two mounting blocks 1 at the slope surface position, and the clamp installation adjustment operation is completed.

[0039] Secondly, when the protection is driven, the wireless controller 25 is powered by the battery 24, and the wireless controller 25 is started by the background remote controller, the wireless controller 25 can start the speed reducer 15, the speed reducer 15 drives the driving shaft 14 to rotate counterclockwise, the driving shaft 14 drives the separation strip 16 to rotate counterclockwise, the separation strip 16 is no longer in contact with the bottom end of the inclined strip 17, so that the fitting cover 19 drives the linkage strip 20 to move downward under the action of its own gravity, the linkage strip 20 drives the other fitting cover 19 to move downward synchronously, and the fitting cover 19 drives the two guide rods 26 to move downward, the guide rods 26 move downward along the inner wall of the mounting block 1. At the same time, the fitting cover 19 drives the inclined strip 17 to move downward, the inclined strip 17 drives the plurality of inclined teeth 18 to move downward, until the inner wall top surface of the fitting cover 19 is fitted with the upper surface of the mounting block 1, at this time, the two fitting covers 19 are respectively covered on the two mounting blocks 1, forming a protection area outside the two mounting blocks 1, and forming a protection area outside the wireless controller 25.

[0040] At the same time, the frame strip 5 rotates counterclockwise, and the support strip 23 rotates counterclockwise synchronously, the support strip 23 drives the inclined pressing strip 21 to rotate counterclockwise, the inclined pressing strip 21 drives the plurality of pressing teeth 22 to rotate counterclockwise, the plurality of pressing teeth 22 are pressed at the right side inclined surface of the inclined strip 17, and the plurality of pressing teeth 22 are engaged and pressed with the inclined teeth 18, so that the plurality of inclined teeth 18 are pressed and locked, and the plurality of inclined teeth 18 lock the inclined strip 17, and the inclined strip 17 is locked and attached to the cover 19.

[0041] At the same time, when the frame strip 5 rotates counterclockwise, the displacement shaft 6 rotates counterclockwise, the displacement shaft 6 rotates counterclockwise along the inner wall of the sliding groove 7, the displacement shaft 6 moves along the inner wall of the sliding groove 7, so that the displacement shaft 6 drives the covering shell 8 to rotate counterclockwise, the covering shell 8 drives the sleeve shell 9 to rotate counterclockwise, the sleeve shell 9 rotates counterclockwise along the inside of the fixed shell 10, so that the covering shell 8 surrounds the outer upper area of the measuring rod 2, and the sleeve shell 9 surrounds the outer upper area of the measuring sleeve 3, and the covering shell 8 and the fixed shell 10 form a surrounding area, and the sleeve shell 9 and the fixed sleeve 12 form a surrounding area. When a non-professional shakes or damages the connection between the measuring rod 2 and the measuring sleeve 3, the hand holds the outer wall of the fixed shell 10, the hand directly contacts the protection teeth 11 to cause damage, or the hand is located on the outer wall of the fixed sleeve 12, and the plurality of protection teeth 13 cause damage to the hands of the non-professional, so as to ensure that the connection between the measuring rod 2 and the measuring sleeve 3 is not disturbed from the outside, and the two mounting blocks 1 are not disturbed and deviated from the outside, so as to ensure that the distance between the two mounting blocks 1 changes, and the distance between the measuring rod 2 and the measuring sleeve 3 changes, and the width monitoring measurement data can be avoided from being disturbed or tampered.

[0042] When the distance between the two mounting blocks 1 increases, the mounting block 1 drives the displacement shaft 6 to move left, the displacement shaft 6 drives the covering shell 8 to move left, the covering shell 8 moves left along the inside of the sleeve shell 9, the mounting block 1 drives the fixed shell 10 to move left, the fixed shell 10 moves left along the outer wall of the sleeve shell 9 and slides, and the fixed shell 10 drives the plurality of protection teeth 11 to move left, so that the sleeve shell 9 and the covering shell 8 can change the length between the measuring rod 2 and the measuring sleeve 3, so that the sleeve shell 9 and the covering shell 8 continuously adapt to the length adjustment to realize effective protection of the upper part of the measuring rod 2 and the measuring sleeve 3. At the same time, the fixed sleeve 12 and the fixed shell 10 can change the length between the measuring rod 2 and the measuring sleeve 3, so that the fixed sleeve 12 and the fixed shell 10 continuously adapt to the length adjustment to realize effective protection of the lower part of the measuring rod 2 and the measuring sleeve 3.

[0043] Finally, when the crack of the slope surface becomes larger during the measurement, the installation block 1 drives the measuring rod 2 to move, the measuring rod 2 moves along the inside of the measuring sleeve 3, so that the measuring rod 2 is away from the distance sensor 4, the distance sensor 4 senses the distance between the measuring sleeve 3 and the distance sensor 4, and the change value of the sensed distance is the change value of the crack width of the slope surface, so that the width value of the crack of the slope surface can be measured, and the wireless controller 25 is used to realize the remote transmission to the background computer.

In the technical solution, the electrical appliance control elements not mentioned belong to the prior art, so they are not shown in the drawings, and will not be described here.

[0045] The above only describes the preferred embodiments of the present application and is not used to limit the present application.
