DETAILED DESCRIPTION

[0014] 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.

[0015] See also Figure 1-Figure 6 The present invention provides a technical solution: a GIS micro-water online monitoring device based on the Internet of Things technology, including a micro-water monitor 1, a GIS device and a driving mechanism, the driving mechanism including two connecting plates 2, two guide rails 3, two sliders 4, a connecting block 5, an elastic expansion joint 6 and a hydraulic chamber 7; Two connecting plates 2 are fixedly installed at both ends of the inner wall of the pipeline of the GIS equipment, and two guide rails 3 are fixedly installed between the two connecting plates 2 and arranged oppositely. Two sliders 4 are slidably connected to the two guide rails 3, and a connecting block 5 is fixedly installed between the two sliders 4. The hydraulic chamber 7 is fixedly installed on the left side of the left connecting plate 2, and a hydraulic plate 71 is slidably connected to the inner wall. The right side of the hydraulic chamber 7 is connected to the external pipeline, and a one-way valve 1 is arranged in the pipeline. The elastic expansion joint 6 is fixedly installed between the inner side of the left connecting plate 2 and the connecting block 5, and is connected to the right pipeline of the hydraulic chamber 7, and a one-way valve 2 is arranged in the pipeline. The left side of the hydraulic chamber 7 is connected to the external hydraulic pump pipeline. The micro-water monitor 1 is fixedly installed on one side of the connecting block 5, and a micro-water monitoring system is arranged inside. The micro-water monitoring system is connected to the external Internet of Things signal, and the elastic expansion joint 6 is connected to the external control valve pipeline. When the micro-water monitor 1 monitors the internal moisture of the pipeline of the GIS equipment, after monitoring an area, the external hydraulic pump is started, and the external hydraulic pump injects liquid into the left side of the hydraulic chamber 7 through the pipeline. The hydraulic pressure pushes the hydraulic plate 71 to slide to the right along the inner wall of the hydraulic chamber 7. The gas on the right side of the hydraulic plate 71 is injected into the elastic expansion joint 6 through the pipeline to stretch it, thereby driving the connecting block 5 to move to the right. The connecting block 5 drives the slider 4 to move on the guide rail 3 to provide stability. The connection block 5 moves to the right and drives the micro-water monitor 1 to move to the right. After moving a distance, it stops. The micro-water monitor 1 is started again to monitor micro-water. Micro-water monitoring can be performed on all areas in the GIS equipment in real time. The monitoring data is more accurate, the monitoring effect is better, and the monitoring is more comprehensive, which avoids the phenomenon that a certain area cannot be monitored, resulting in the increase of moisture in this area and cannot be discovered in time. When the micro-water monitor 1 moves to the limit position, the elastic expansion joint 6 extends to the limit length, then the external control valve opens, and the air pressure inside the elastic expansion joint 6 returns to normal, so that the micro-water monitoring work is carried out from left to right in a cycle through elastic reset, ensuring the comprehensiveness of the monitoring; The moisture inside the GIS equipment is detected through the micro-water monitoring system, and the monitoring data is transmitted to the external network through signals, and received and monitored in real time through the external network.

[0016] Two tooth plates 8 are fixed between the two connecting plates 2, and the two tooth plates 8 are arranged opposite to each other. Gears 41 are installed on the outer sides of the two sliders 4, and fan blades 42 are fixed above the gears 41, and the two fan blades 42 are arranged opposite to each other. The gear 41 meshes with the toothed plate 8; When the slider 4 moves to the right, the micro-water monitor 1 moves to the right, and the slider 4 drives the gear 41 to move to the right. The gear 41 rotates by meshing with the toothed plate 8, and the gear 41 drives the fan blades 42 to rotate. The two fan blades 42 rotate relative to each other, thereby fanning in opposite directions, which can concentrate the internal gas in the middle position. The micro-water monitor 1 collects more sufficient gas, further improves the accuracy of the monitoring data, and greatly improves the monitoring quality.

[0017] A sleeve 72 is fixed to the right side of the inner wall of the hydraulic chamber 7, a sliding plug 73 is slidably connected to the inner wall of the sleeve 72, and a spring 74 is fixed between the left side of the sliding plug 73 and the right side of the hydraulic plate 71; An extrusion rod 411 is fixed to the bottom of the gear 41, the interior of the connection block 5 is hollow, and a slide plate 51 is slidably connected to the upper and lower inner walls, a spring 52 is fixed between the two slide plates 51, and a lifting rod 53 is fixed to the outer sides of the two slide plates 51. The outer end of the lifting rod 53 and the inner end of the extrusion rod 411 are both spherical, and after the gear 41 rotates, the extrusion rod 411 and the lifting rod 53 contact each other, and the middle of the connection block 5 is connected to the right side of the sleeve 72 by a hose; When the hydraulic plate 71 moves to the right, the spring 1 74 is squeezed to deform, and the spring 1 74 generates a reaction force, thereby buffering the hydraulic plate 71, avoiding the instability of the micro-water monitor 1 when it stops moving, resulting in vibration damage to the internal structure, and protecting the micro-water monitor 1, so that it can always maintain high-precision monitoring; At the same time, when the micro-water monitor 1 is about to stop moving to the right, the gear 41 rotates to drive the squeezing rod 411 to rotate around its center until the squeezing rod 411 contacts the lifting rod 53 and squeezes the lifting rod 53. The lifting rod 53 is forced to push the slide plate 51 to move inward, and the two slide plates 51 approach each other. The spring 2 52 is deformed by the force, and the gas between the two is squeezed and injected into the sleeve 72 through the pipeline, pushing the sliding plug 73 to move. The sliding plug 73 further applies pressure to the spring 1 74, so that the buffering strength of the hydraulic plate 71 when it moves to the right is increased, further ensuring the stability of the micro-water monitor 1 after it stops moving.

[0018] The outer side of the slider 4 is provided with a countersunk hole 43, the inner wall of the countersunk hole 43 is slidably connected with an ups and downs block 431, and a spring 432 is fixed between the outer side of the ups and downs block 431 and the outer side of the inner wall of the countersunk hole 43, and a push-pull rod 44 is bearing-connected between the ups and downs block 431 and the slider 4; When the extrusion rod 411 and the lifting rod 53 come into contact with each other, the two interact with each other, and the extrusion rod 411 is subjected to the force to drive the gear 41 to move upward, and the gear 41 drives the undulating block 431 to slide along the inner wall of the countersunk hole 43 through the push-pull rod 44, and the spring three 432 is deformed by the force. After that, when the extrusion rod 411 is out of contact with the lifting rod 53, the spring three 432 generates a reaction force to pull the push-pull rod 44 to quickly reset, thereby driving the fan blade 42 to shake up and down through the gear 41, so as to shake off the dust on the fan blade 42 to improve its rotation smoothness, and when the fan blade 42 is quickly reset downward, the gas inside it can be quickly pushed, so that the gas is more concentrated in the middle position, so as to further improve the micro-water monitoring quality of the micro-water monitor 1.

[0019] The movable distance of the slide plate 51 is greater than the movable distance of the undulating block 431, and the meshing portion of the tooth plate 8 and the gear 41 is greater than the movable distance of the undulating block 431; During the up-and-down movement of the undulating block 431, since the up-and-down movement distance of the undulating block 431 is smaller than the up-and-down movement distance of the slide plate 51, the slide plate 51 can smoothly squeeze the gas into the sleeve 72, providing high-strength buffering. At the same time, since the up-and-down movement of the undulating block 431 can prevent the slide plate 51 from moving too far, resulting in more gas being squeezed into the sleeve 72, and prevent the hydraulic plate 71 from being subjected to too large a reaction force when moving to the right, resulting in a slow speed when stopping, thereby relatively improving the monitoring efficiency; Since the meshing portion of the toothed plate 8 and the gear 41 is greater than the distance that the undulating block 431 moves up and down, it is possible to prevent the toothed plate 8 from being disengaged from the gear 41 when moving up and down, thereby ensuring that the work of concentrating the gas in the middle is continuously and effectively carried out.

[0020] The moving distance of the micro-water monitor 1 each time is adjusted by the pressure of the external hydraulic pump.

[0021] The distance between the guide rail 3, the tooth plate 8 and the two connecting plates 2 is adjusted by the length of the pipeline of the GIS equipment; By controlling the pressure of the external hydraulic pump, the thrust on the hydraulic plate 71 is changed, so that the amount of gas entering the elastic expansion joint 6 is controlled, and the distance of each movement of the micro-water monitor 1 is controlled, the operation is convenient and efficient, and the monitoring quality of the micro-water monitor 1 is further improved; The length of the guide rail 3, the tooth plate 8, and the distance between the connecting plates 2 can be freely adjusted according to the length of the GIS equipment pipeline to ensure comprehensive monitoring.

[0022] The micro-water monitoring system includes a sensor monitoring module and a remote monitoring module. The remote monitoring module is electrically connected to the sensor monitoring module. The sensor monitoring module is used to monitor and analyze the moisture content in the GIS equipment in real time by using sensors, and transmit the data to the background system for analysis and processing. The remote monitoring module is used to realize the real-time measurement, data transmission and early warning and forecasting functions of moisture with data analysis as the core, and the moisture situation in the GIS equipment can be grasped in real time through remote monitoring. The remote monitoring module includes a real-time measurement unit, a data transmission unit and an early warning unit. The real-time measurement unit is used to measure the moisture content in the environment in real time, the data transmission unit is used to transmit the monitored data to the background system through the network, and the early warning unit is used to analyze and warn based on the measured data; The micro-water monitoring system can measure the moisture content in the environment in real time to ensure the accuracy and timeliness of the data. The monitored data can be transmitted to the background system through the communication network to facilitate remote monitoring and management. The micro-water monitoring system can also analyze and issue early warnings based on the measured data to prevent the impact of excessive or low moisture on equipment or the environment.
