[0025] Specifically, the limiting component 6 includes a mounting plate 61, a first fixing ring 63, a second fixing ring 64, and a fixing rope 65. The second fixing ring 64 is fixed to the surfaces of the angle monitoring cylinder 1, the lateral monitoring cylinder 5, and the longitudinal monitoring cylinder 10. The mounting plate 61 is mounted on the surfaces of the third sliding block 2, the first sliding block 4, and the second sliding block 7. The first fixing ring 63 is fixed to the surface of the mounting plate 61, and a fixing rope 65 connects the first fixing ring 63 and the second fixing ring 64.

[0026] By adopting the above technical solution, the fixing rope 65 passes through the first fixing ring 63 and the second fixing ring 64 and is tied tightly, which can conveniently fix the initial position of the first sliding block 4, the second sliding block 7 and the third sliding block 2, making the transportation of the device convenient. The device can be installed by untying the fixing rope 65.

[0027] Specifically, the limiting component 6 also includes a threaded sleeve 66, a threaded hole 67, and a positioning rod 68. The positioning rod 68 is fixed to the side surface of the mounting plate 61, and the threaded sleeve 66 is installed on the surface of the positioning rod 68. The third sliding block 2, the first sliding block 4, and the second sliding block 7 have threaded sleeves 66 at positions corresponding to the threaded sleeves 66.

[0028] By adopting the above technical solution, the threaded sleeve 66 on the surface of the positioning rod 68 engages with the threaded hole 67, which can conveniently fix the mounting plate 61.

[0029] Specifically, the support block 9 has a storage structure 62 inside, which includes a limiting slide rail 621, a storage drawer 622, and a storage slot 623. The support block 9 has a storage slot 623 inside, the inner surface of which is fixed with the limiting slide rail 621, and the storage drawer 622 is connected inside the storage slot 623.

[0030] By adopting the above technical solution, after the device is installed, the storage drawer 622 is pulled to move on the surface of the limit slide rail 621 and move out of the storage slot 623. The storage drawer 622 can store and preserve the removed fixing rope 65 and mounting plate 61.

[0031] In this embodiment, the fixed base 8 is installed on the flat top of the dam slope, allowing the longitudinal monitoring cylinder 10 to move and be fixed on the surface of the crossbeam 11 at the upper end of the support block 9. The first sliding block 4 moves inside the longitudinal monitoring cylinder 10, allowing the hammer head to enter the slope. When the slope deforms, the first sliding block 4 moves, allowing for the measurement of longitudinal deformation. The connector is inserted into the slope, and when the slope moves, the second sliding block 7 can move inside the transverse monitoring cylinder 5, thereby measuring transverse deformation. The third sliding block 2 drives the angle monitoring structure 3 to rise and fall inside the angle monitoring cylinder 1, causing the angle adjustment plate to fit against the slope, thus allowing for the measurement of the deformation angle, which is convenient. The monitoring of slope displacement is completed, and the threaded sleeve 66 on the surface of the positioning rod 68 engages with the threaded hole 67, which can easily fix the mounting plate 61. The fixing rope 65 passes through the first fixing ring 63 and the second fixing ring 64 and is tied tightly, which can easily fix the initial position of the first sliding block 4, the second sliding block 7 and the third sliding block 2, facilitating the transportation of the device.

After the device is installed, the storage drawer 622 is pulled to move on the surface of the limit slide rail 621 and move out of the storage slot 623. The storage drawer 622 can store and preserve the removed fixing rope 65 and mounting plate 61.

[0032] Example 2

[0033] The difference between this embodiment and Embodiment 1 is that the protective component 12 includes a protective sleeve 121, a protective inner cylinder 122, and a connecting ring 123. The protective sleeve 121 is sleeved around the outside of the spring 13, and the protective inner cylinder 122 is connected inside the protective sleeve 121. The connecting ring 123 is fixed to one side of the protective sleeve 121 and the protective inner cylinder 122 that are far apart from each other.

[0034] By adopting the above technical solution, the protective sleeve 121 and the protective inner cylinder 122 are installed through the connecting ring 123. The sliding connection between the two can shield and protect the spring 13, preventing it from being exposed to air and corroding.

[0035] Specifically, the protective component 12 also includes an activated carbon plate 124, an adhesive layer 125, and absorbent cotton 126.

[0036] By adopting the above technical solution, the activated carbon plate 124 is fixed by the adhesive layer 125. It works in conjunction with the moisture-absorbing cotton 126 to absorb the moisture in the protective sleeve 121, keeping the air dry and preventing the spring 13 from rusting.

[0037] In this embodiment, the protective sleeve 121 and the protective inner cylinder 122 are installed through the connecting ring 123. The sliding connection between the two can shield and protect the spring 13, preventing it from being exposed to the air and corroding. The activated carbon plate 124 is fixed by the adhesive layer 125. It works with the moisture-absorbing cotton 126 to absorb the moisture inside the protective sleeve 121, keeping the air dry and preventing the spring 13 from rusting.

[0038] The structure and working principle of the angle monitoring structure 3 in this invention have been disclosed in a dam slope displacement monitoring device disclosed in Chinese patent application number 202420833249.X. Its working principle is that the angle adjustment plate descends and contacts the slope below, and the angle adjustment plate is rotatably connected to the third sliding block 2 through the rotating block. The entire surface of the angle adjustment plate will be in contact with the slope, thus producing an angle change. The third pointer will rotate with the rotating block. The angle of the slope is when the third pointer is aligned with the scale on the ring scale. When the slope is displaced, the angle adjustment plate will change angle, and the third pointer will also rotate to adjust the angle. In this way, the slope angle change can be monitored.

[0039] The working principle and usage process of this utility model are as follows: When using this utility model, the fixed base 8 is installed on the flat top of the dam slope. The longitudinal monitoring cylinder 10 moves and is fixed on the surface of the crossbeam 11 at the upper end of the support block 9. The first sliding block 4 moves inside the longitudinal monitoring cylinder 10, allowing the hammer head to enter the slope. When the slope deforms, the first sliding block 4 moves, allowing for measurement of longitudinal deformation. The connector is inserted into the slope. When the slope moves, the second sliding block 7 moves inside the transverse monitoring cylinder 5, allowing for measurement of transverse deformation. The third sliding block 2 drives the angle monitoring structure 3 to rise and fall inside the angle monitoring cylinder 1, causing the angle adjustment plate to fit against the slope, thus allowing for measurement of the deformation angle and convenient monitoring of slope displacement. The threaded sleeve 66 on the surface of the positioning rod 68 engages with the threaded hole 67, facilitating the fixation of the mounting plate 61 and the fixing rope 6. 5. By passing through the first fixing ring 63 and the second fixing ring 64 and fastening them, the initial positions of the first sliding block 4, the second sliding block 7 and the third sliding block 2 can be easily fixed, facilitating the transportation of the device. The device can be installed by untying the fixing rope 65. After the device is installed, pull the storage drawer 622 to move it on the surface of the limit slide rail 621 and move it out of the storage slot 623. The storage drawer 622 can store and preserve the removed fixing rope 65 and the mounting plate 61, etc. The protective sleeve 121 and the protective inner cylinder 122 are installed through the connecting ring 123. The sliding connection between the two can shield and protect the spring 13 to prevent it from being exposed to the air and rusting. The activated carbon plate 124 is fixed through the adhesive layer 125. It works with the moisture-absorbing cotton 126 to absorb the moisture in the protective sleeve 121, keeping the air dry and preventing the spring 13 from rusting.
