[0013] The following is a further non-limiting detailed description of the technical solution of the present invention in conjunction with the preferred embodiments and the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0014] See also Figure 1-Figure 7 , the present invention provides a technical solution: a GIL settlement and displacement monitoring device for a power transmission corridor foundation, comprising a power transmission corridor 1 and a monitoring cavity 2, wherein the monitoring cavity 2 is located on one side of the middle of the power transmission corridor 1; The monitoring chamber 2 includes a motor 21, a disc 22, a connecting block 23, a push-pull rod 24, a lifting rod 25 and a sleeve block 26. The motor 21 is fixedly mounted on the inner wall of the monitoring chamber 2. The disc 22 is fixedly connected to the output end of the motor 21. The connecting block 23 is fixedly mounted in the middle of the disc 22. The push-pull rod 24 is arranged inside the connecting block 23. The sleeve block 26 is fixedly mounted on one side of the inner wall of the monitoring chamber 2. The lifting rod 25 is slidably connected in the sleeve block 26. An arc disc 251 is fixed on the outer side of the lifting rod 25. The outer end of the push-pull rod 24 is spherical and contacts the arc disc 251 after rotation. A laser emitter 3 is fixed on the bottom end of the lifting rod 25. The laser emitter 3 is located on one side of the middle of the transmission corridor 1 and is aligned with the transmission corridor 1. When monitoring the settlement and displacement, the motor 21 runs, driving the disc 22 to rotate, and the disc 22 drives the connecting block 23 to rotate around its center, thereby driving the push-pull rod 24 to rotate. The push-pull rod 24 rotates until it contacts the arc disc 251 and presses the arc disc 251 to move downward. The arc disc 251 drives the laser emitter 3 to move downward through the lifting rod 25. At the same time, the laser emitter 3 runs to emit laser, and monitors the settlement and displacement of the transmission corridor 1 from top to bottom, so as to promptly detect whether the transmission corridor 1 has displacement and settlement, so as to avoid loosening or breaking of the equipment connection caused by the settlement and displacement of the transmission corridor 1, thereby causing equipment failure, preventing the stability and safety of power transmission from being affected, affecting large-area power supply, and avoiding displacement-induced current leakage, short circuit, and even serious accidents such as fire or explosion.

[0015] The laser emitter 3 is internally provided with a laser emission module, a settlement monitoring module and a displacement monitoring module. The laser emission module is electrically connected to the settlement monitoring module and the displacement monitoring module respectively. The laser emission module is used to emit laser through the laser emitter 3. The settlement monitoring module is used to irradiate the transmission corridor 1 from top to bottom through laser, so as to determine whether the transmission corridor 1 has settled. The displacement monitoring module is used to irradiate the transmission corridor 1 through laser, so as to determine whether the transmission corridor 1 has displaced. The monitoring process of the settlement monitoring module and the displacement monitoring module is as follows: Step S1, the laser emitter 3 runs and emits a laser, then the laser emitter 3 moves downward, and the laser irradiates the upper surface of the transmission corridor 1 until it is blocked, at which time the position data L1 is recorded, and then the laser irradiates the lower surface of the transmission corridor 1 until the transmission corridor 1 can no longer block the laser, at which time the position data L2 is recorded; Step S2, in the process from L1 to L2, the distance between the laser emission position and the position blocked by the transmission corridor 1 is D1, and because the transmission corridor is circular, D1 is from large to small, and then from small to large. At this time, the smallest D1 data is collected, that is, the distance between the middle position of the transmission corridor 1 and the laser emitter 3, and then the laser emitter 3 is reset; Step S3, repeating steps S1 to S2 once every cycle N, and monitoring whether the data of L1 and L2 change through the settlement monitoring module. When a change occurs, it is determined that the transmission corridor 1 has settled, or has an up-and-down displacement, and the settlement or displacement data is monitored. When there is no change, it indicates that no settlement or up-and-down displacement occurs; Step S4, monitor whether the minimum D1 data changes through the displacement monitoring module. If it changes, it is determined that the transmission corridor 1 has a left-right displacement, and the displacement data is monitored. If there is no change, it means that there is no left-right displacement. Monitoring is performed in this manner, and the monitoring period is adjustable, so as to monitor in real time whether the transmission corridor 1 has displacement and settlement, and record the displacement and settlement data in real time, so as to facilitate subsequent operators to perform maintenance and reset of the transmission corridor 1.

[0016] A sliding hole 231 is provided in the middle of the connecting block 23, a slider 241 is fixed to the outer side of the push-pull rod 24, and the slider 241 is slidably connected in the sliding hole 231, a sleeve 232 is provided on one side of the slider 241, and the sleeve 232 is sleeved on the outer side of the push-pull rod 24 and located in the sliding hole 231, an elastic spring 233 is provided between the slider 241 and the sleeve 232, a threaded rod 234 is fixed to the outer end of the sleeve 232, a threaded block 221 is fixed to the surface of the disc 22, and the threaded rod 234 and the threaded block 221 are threadedly connected; When the push-pull rod 24 rotates to contact the arc disk 251, the arc disk 251 is pressed to move downward, and then the spherical part of the push-pull rod 24 rubs against the arc part of the arc disk 251 and presses over the arc disk 251. In this process, the push-pull rod 24 is forced to move in the opposite direction, slides in the sliding hole 231 through the slider 241, and is limited by the sleeve 232, so that the elastic spring 233 is deformed. Through the reverse displacement of the push-pull rod 24, the speed of the lifting rod 25 moving downward can be relatively slowed down, avoiding the phenomenon that the laser emitter 3 cannot monitor in time due to excessive movement speed, and the downward movement distance of the laser emitter 3 can be controlled, and the monitoring efficiency is relatively improved.

[0017] A hydraulic chamber 27 is fixed above the inner wall of the monitoring chamber 2, and a hydraulic plate 271 is slidably connected to the inner wall of the hydraulic chamber 27. The bottom of the hydraulic plate 271 is connected to the upper end of the lifting rod 25 by a bearing. Through holes 272 are provided on the left and right sides of the hydraulic plate 271. The upper and lower parts of the hydraulic plate 271 are filled with magnetorheological fluid, and the upper part is connected to the inner wall of the hydraulic chamber 27 by a spring. When the lifting rod 25 moves downward, it drives the hydraulic plate 271 to slide downward along the inner wall of the hydraulic chamber 27, pulling the spring to deform under force, thereby performing primary buffering. At the same time, the magnetorheological fluid is squeezed and flows back and forth through the through hole 272, thereby further relieving pressure and buffering, performing secondary buffering, and further controlling the speed of the laser emitter 3 moving downward. On the one hand, it ensures the monitoring quality, and on the other hand, it prevents the laser emitter 3 from moving downward too fast, causing damage to the internal electronic components, thereby protecting the laser emitter 3. Afterwards, when the push-pull rod 24 is out of contact with the arc disk 251, the reaction force generated by the spring pulls the hydraulic plate 271 to reset, thereby driving the laser emitter 3 to reset through the lifting rod 25, and the motor 21 rotates, causing the laser emitter 3 to repeatedly move up and down, thereby performing real-time monitoring of the settlement and displacement of the power transmission corridor 1, and the operation is automated, convenient and efficient.

[0018] A chamber 28 is fixed to the inner wall of the monitoring chamber 2, a gear block 29 is fixed to the right side of the chamber 28, and a gear 235 is fixed to the outer end of the threaded rod 234; A tooth is provided above the tooth block 29, and after the disk 22 rotates, the gear 235 meshes with the teeth of the tooth block 29, the length of the tooth block 29 is five times the thickness of the gear 235, and in the initial state, after the disk 22 rotates, the gear 235 meshes with the middle part of the tooth block 29; After several times of settlement displacement monitoring, the push-pull rod 24 moves back and forth, so that the elastic spring 233 is deformed many times and fatigue increases. At this time, each time the push-pull rod 24 rotates, it drives the gear 235 to rotate around the center of the disk 22, so that it can mesh with the teeth on the tooth block 29 each time, and the gear 235 is driven to rotate slightly through the meshing. After the disk 22 rotates many times, the gear 235 rotates continuously, driving the threaded rod 234 to rotate and move in the threaded hole of the threaded block 221, thereby driving the sleeve 232 to rotate and move continuously. After the sleeve 232 moves, the push-pull rod 2 When the elastic spring 233 contacts and squeezes the circular arc disk 251, the slider 241 makes the reaction force generated by the compression of the elastic spring 233 relatively stable, thereby avoiding affecting the downward movement distance of the laser emitter 3 and preventing affecting the monitoring accuracy of the settlement displacement. The elastic force loss of the elastic spring 233 can be automatically compensated until the elastic spring 233 is completely scrapped, and the elastic spring 233 is replaced, and the gear 235 is reversely rotated to reset, so as to facilitate the replacement of the elastic spring 233. The monitoring device as a whole can be continuously used, and only individual components need to be replaced, and the cost is relatively greatly reduced.

[0019] The inner wall of the chamber 28 is slidably connected with a slide plate 281, the slide plate 281 is connected to the inner wall of the chamber 28 by a spring, the left side of the slide plate 281 is filled with magnetorheological fluid, and the left side of the chamber 28 is connected to the upper pipeline of the hydraulic chamber 27; Gear 235 is magnetic; As the gear 235 rotates around the center of the disk 22, the push-pull rod 24 and the arc disk 251 contact and squeeze each other, and the gear 235 is aligned with the magnetorheological fluid on the left side of the slide 281. At this time, under the influence of the magnetic force, the magnetorheological fluid on the left side of the slide 281 changes from magnetic neutrality to magnetism due to magnetic induction under the action of the magnetic field, and interacts with each other to form a "chain" structure, so that it changes from liquid to viscoplastic in an instant, showing the Bingham fluid characteristics of high viscosity and low fluidity. At this time, the hydraulic plate 271 slides downward along the inner wall of the hydraulic chamber 27, and the chamber 2 cannot be extracted through the pipeline. 8, so that the buffering effect is guaranteed to improve the accuracy of the monitoring data. After that, when the gear 235 rotates to the magnetorheological fluid away from the left side of the slide plate 281, the magnetorheological fluid magnetic field disappears, and in the absence of a magnetic field, the magnetorheological fluid exhibits the characteristics of a low-viscosity Newtonian fluid. At this time, when the hydraulic plate 271 is reset, part of the magnetorheological fluid can impact into the chamber 28 through the pipeline, thereby accelerating the reset speed of the laser transmitter 3, so as to ensure the monitoring efficiency during high-frequency monitoring, so as to timely monitor whether the transmission corridor 1 has any settlement and displacement phenomenon.

[0020] The interior of the sleeve block 26 is hollow and is provided with a tooth plate 261. A tooth plate 252 is fixed to the outer side of the lifting rod 25 and meshes with the tooth plate 261. A push-pull plate 262 is fixed to the left side of the tooth plate 261, a support rod 263 is fixed above the push-pull plate 262, and the right side of the tooth plate 261 is connected to the right side of the inner wall of the sleeve block 26 by a spring; When the push-pull rod 24 rotates around the center of the disk 22, the push-pull rod 24 first contacts the arc disk 251 and then breaks contact, so that the laser emitter 3 first moves downward and then resets upward. Then the push-pull rod 24 contacts the support rod 263 and pushes the support rod 263 to move to the left. The support rod 263 drives the tooth plate 261 to move, and the tooth plate 261 engages with the tooth disk 252, thereby driving the tooth disk 252 to rotate. The tooth disk 252 drives the laser emitter 3 to rotate through the lifting rod 25. At the same time, the spring is deformed by force. When the push-pull rod 24 is disengaged from the support rod 263, the support rod 263 is disengaged from the support rod 263. After the contact is released, the spring generates a reaction force to pull the tooth plate 261 to reset, thereby resetting the toothed disc 252, and causing the laser emitter 3 to rotate alternately clockwise and counterclockwise around the center of the lifting rod 25. At this time, by starting the laser emitter 3, the laser is emitted to illuminate one side of the transmission corridor 1, so as to monitor whether the transmission corridor 1 is in a horizontal plane, or whether there are other objects on the surface of the transmission corridor 1, such as animal feces and mud, so as to avoid the subsequent monitoring data from being inaccurate due to these objects.

[0022] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them. Although the present invention has been described in detail with reference to the above embodiments, a person skilled in the art should understand that the technical solutions described in the above embodiments can still be modified, or some of the technical features can be replaced by equivalents, and these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
