Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
[0018] Example 1

[0020] An inclinometer 3 is vertically arranged in the casing 1, and a cable 2 is connected to the top of the inclinometer 3. The inclinometer 3 is inserted into the casing 1, and the inclinometer 3 is pulled by the cable 2 to move in the casing 1, so as to monitor different geological disasters;
[0021] The left and right inner walls of the casing 1 are both provided with slide grooves 7. There are two slide grooves 7, which are symmetrically provided on the inner walls of the casing 1. The two slide grooves 7 can be provided on the left and right inner walls of the casing 1, or on the front and rear inner walls, which helps the inclinometer 3 to move its position in the casing 1.
[0022] At least two fixing sleeves 4 are mounted on the outer side of the inclinometer 3. The two fixing sleeves 4 are fixed to the upper and lower ends of the inclinometer 3 respectively. When the inclinometer 3 moves, the two fixing sleeves 4 are driven to move together.
[0023] The slide grooves 7 are provided with pulleys 5, and the pulleys 5 are connected to the corresponding fixed sleeves 4 through connecting rods 6. Figure 1 As shown, there are four pulleys 5, two pulleys 5 on the left are arranged in the left slide groove 7, the upper left pulley 5 is fixed to the left wall of the upper fixed sleeve 4 through the connecting rod 6, the lower left pulley 5 is fixed to the left wall of the lower fixed sleeve 4 through the connecting rod 6, and the two pulleys 5 on the right are arranged in the thick slide groove 7, the upper right pulley 5 is fixed to the right wall of the upper fixed sleeve 4 through the connecting rod 6, and the lower right pulley 5 is fixed to the right wall of the lower fixed sleeve 4 through the connecting rod 6. The pulleys 5 slide up and down along the length direction of the slide groove 7, so that the inclinometer 3 can move up and down stably in the casing 1;
[0024] The slide groove 7 is provided with a housing 12, and the housing 12 is connected to the fixed sleeve 4 through a connecting rod 13. The housing 12 is located in the slide groove 7, and the right side wall of the left housing 12 is fixed to the fixed sleeve 4 through the connecting rod 13, and the left side wall of the right housing 12 is fixed to the fixed sleeve 4 through the connecting rod 13; a top plate 10 is horizontally provided on the outer side of the housing 12, such as Figure 1 As shown, the upper top plate 10 is horizontally arranged above the housing 12, and the lower top plate 10 is horizontally arranged below the housing 12; a through slot communicating with the inside and outside is opened on the housing 12, and a slide plate 9 is independently installed in the through slot, as shown in FIG. Figure 2 As shown, a through slot communicating with the inside and outside is provided on the top of the housing 12, and the slide plate 9 slides up and down along the groove depth direction of the through slot; one end of the slide plate 9 passes through the through slot and is fixed on the top plate 10, and the other end is in the housing 12, and the upper end of the slide plate 9 is fixed on the top plate 10, and the top plate 10 is driven to move when the slide plate 9 moves; a spring 8 is mounted on the slide plate 9 between the top plate 10 and the housing 12, as shown in FIG. Figure 2As shown, the upper end of the spring 8 is fixed to the bottom of the top plate 10, and the lower end of the spring 8 is fixed to the top of the housing 12, and the top plate 10 is continuously supported upward by the spring 8; a rotating shaft 14 is horizontally installed in the housing 12, as shown in FIG. Figure 2 As shown, the left end of the rotating shaft 14 is mounted on the left inner wall of the housing 12, and the right end is mounted on the right inner wall of the housing 12 through a driving member; a driving member for driving the rotating shaft 14 to rotate is mounted on the inner wall of the housing 12, and the driving member is a prior art, generally a motor or a servo motor, the power output end of the motor is connected to the right end of the rotating shaft 14, and the rotating shaft 14 is driven to rotate in the housing 12 by the motor; a gear 15 with only half of the gear teeth is mounted on the rotating shaft 14, as shown in FIG. Figure 3 As shown, the gear 15 is a gear of special structure, with only half of the gear teeth; a rack 11 meshing with the gear 15 is fixed on the slide plate 9, and the rack 11 is installed on the slide plate 9, and the slide plate 9 meshes with the gear 15 through the rack 11; this paragraph of text as a whole constitutes a driving assembly for pulling the slide plate 9 into the shell 12. When the driving assembly is used, the driving member drives the shaft 14 to rotate clockwise, and the gear 15 rotates with the shaft 14. The gear teeth of the gear 15 mesh with the rack 11, driving the lower end of the slide plate 9 to move into the shell 12, driving the top plate 10 to move toward the shell 12, and the spring 8 is compressed by force. When the gear teeth of the gear 15 rotate to disengage from the rack 11, the spring 8 recovers its deformation after losing the force, lifts up the top plate 10, and the lower end of the slide plate 9 returns to the upper half of the housing 12. The rotating shaft 14 continues to rotate and repeats the above process until the top plate 10 clears the debris in the slide groove 7. Of course, the driving component can also use an electric push rod. The electric push rod is a prior art. It is an electric drive device that converts the rotational motion of the motor into the linear reciprocating motion of the push rod. The outer shell of the electric push rod is fixed to the inner bottom of the housing 12, and the push rod of the electric push rod is located at At the lower end of the slide 9, an electromagnet is installed between the push rod and the lower end of the slide 9. When in use, the electromagnet is energized, the push rod of the electric push rod is connected to the lower end of the slide 9, the electric push rod is shortened, and the slide 9 is driven to move downward, the spring 8 is compressed by force, and when the spring 8 reaches the maximum deformation, the electromagnet is powered off, the spring 8 loses the force and recovers the deformation, driving the top plate 10 to impact the debris in the chute 7, and the debris is pushed out of the chute 7 to ensure the normal use of the pulley 5; this paragraph of text as a whole constitutes a cleaning component for cleaning the debris in the chute 7. When the cleaning component is used, when it is necessary to clean the debris in the chute 7 , the movable top plate 10 contacts the debris, and the slide plate 9 is pulled toward the shell 12 through the driving component. The top plate 10 moves toward the shell 12, and the spring 8 is compressed. When the spring 8 is at the maximum deformation, the driving component is released, and the spring 8 recovers its deformation after losing the force, pushing the top plate 10 to impact the debris, and the kinetic energy generated by the spring 8 recovering the deformation is used to push the debris out of the slide groove 7, thereby ensuring the normal movement of the pulley 5 in the slide groove 7; of course, in the cleaning component, the width of the top plate 10 is slightly smaller than the groove width of the slide groove 7, which facilitates the movement of the top plate 10 in the slide groove 7 and prevents the top plate 10 from being stuck in the slide groove 7.
[0025] When this embodiment is used, the inclinometer 3 is inserted into the casing 1, the pulley 5 is inserted into the corresponding slide groove 7, and the inclinometer 3 is pulled by the cable 2 to move in the casing 1 to detect geological disasters. When stones and other debris appear in the slide groove 7 to block the movement of the pulley 5, the cable 2 encounters resistance, and the debris in the slide groove 7 is cleaned by the cleaning component, so that the pulley 5 can move smoothly along the slide groove 7 to prevent the pulley 5 from derailing.
[0026] Example 2
[0027] This embodiment further illustrates the technology. Figure 2 As shown, when the spring 8 is in a natural state, the distance between the lower end of the slide plate 9 and the inner bottom of the shell 12 is 8 cm to 10 cm. This distance will directly affect the impact force of the top plate 10 hitting the debris and the volume of the shell 12. If the distance is too large, the volume of the shell 12 will be too large, which will waste materials. If the distance is too small, the length of the spring 8 that is contracted is insufficient, resulting in too little impact force of the top plate 10 on the debris after the spring 8 is released, affecting the cleaning effect of the top plate 10. The distance can be selected from any length of 8 cm, 10 cm, 9 cm and 8 cm-10 cm. In this embodiment, after the gear teeth of the gear 15 rotate, the lower end of the slide plate 9 rests against the inner bottom of the shell 12.
[0028] Example 3
[0029] This embodiment further illustrates the technology. Figure 2 As shown, the shell 12 is provided with two through slots, in which two slide plates 9 are installed, and the upper ends of the two slide plates 9 are fixed on the top plate 10. There are two slide plates 9, and the top plate 10 is driven up and down by the two slide plates 9 at the same time, so as to ensure the stability of the top plate 10 during movement, prevent the top plate 10 from deflecting during movement, and enable the top plate 10 to stably move along the length direction of the slide plates 9.
[0030] Example 4
[0031] This embodiment further illustrates the technology. Figure 3 As shown, the cross section of the top plate 10 is a triangular structure, and the upper end of the top plate 10 is a top angle structure, which reduces the contact area between the top plate 10 and the debris, increases the local force on the debris, and helps the top plate 10 to clean the debris in the chute 7.
