DETAILED DESCRIPTION

[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 cloud platform-based integrated online monitoring device for intelligent environment of a power distribution room, comprising a cloud platform system, an environmental monitor 1 and a driving mechanism, the driving mechanism comprising a chamber 2, a motor 21, an output shaft 22, a pneumatic chamber 23, a connecting shaft 24 and an elastic expansion joint 25; The chamber 2 is installed on the top of the power distribution room, the motor 21 is fixedly installed on the upper inner wall of the chamber 2, the output shaft 22 is fixedly connected to the output end of the motor 21, the connecting shaft 24 is fixedly connected to the output shaft 22 through the air pressure chamber 23, the elastic expansion joint 25 is connected to the bottom end of the connecting shaft 24, the environmental monitor 1 is fixedly installed on the outer end of the elastic expansion joint 25, and is arranged downward, the inner wall of the air pressure chamber 23 is slidably connected with a magnetic plate 231, and the bottom of the magnetic plate 231 is in contact with the bottom of the inner wall of the air pressure chamber 23. The parts are connected by springs, an electromagnetic device 232 is fixed on the inner wall of the air pressure chamber 23, and it has magnetism after being energized, and the magnetic pole is opposite to the magnetic plate 231, an air pipe 241 is arranged inside the connecting shaft 24, and a one-way valve 1 is arranged inside the air pipe 241, and the two ends of the air pipe 241 are respectively connected to the bottom of the air pressure chamber 23 and the inside of the elastic expansion joint 25, the bottom of the air pressure chamber 23 is connected to the external pipeline, and a one-way valve 2 is arranged in the pipeline, and the elastic expansion joint 25 is connected to the external control valve pipeline; The environmental monitor 1 is started to monitor the comprehensive environment of the power distribution room. At this time, the motor 21 rotates and drives the output shaft 22 to rotate. The output shaft 22 drives the connecting shaft 24 to rotate through the air pressure chamber 23. The connecting shaft 24 drives the environmental monitor 1 to rotate around the center of the motor 21 through the elastic expansion joint 25. The environmental monitor 1 realizes circular rotation and uniformly monitors the equipment in the power distribution room, so that each device can be monitored. At the same time, for the equipment in the internal and external areas of the power distribution room, the electromagnetic device 232 is powered on by starting it, thereby generating magnetism. The magnetic pole is opposite to the magnetic plate 231, thereby generating a magnetic repulsion force, pushing the magnetic plate 231 to move downward, and the spring is subjected to force. When the magnetic plate 231 slides downward along the inner wall of the air pressure chamber 23, the gas below it is input into the elastic expansion joint 25 through the air pipe 241, causing it to stretch slightly. Then the electromagnetic device 232 is powered off and loses its magnetism. The spring generates a reaction force to reset the magnetic plate 231 and extract gas from the outside through the pipeline. The above operation is repeated to make the elastic expansion joint 25 slowly extend, driving the environmental monitor 1 to move gradually outward. When it rotates around the center of the motor 21, the monitoring range is gradually increased, and the equipment in the area outside the center of the distribution room can be monitored, so as to achieve the effect of all-round and no-dead-angle monitoring of all equipment, and the monitoring quality is greatly improved.

[0015] The environment monitor 1 is internally provided with an integrated online environment monitoring system, which is electrically connected to the cloud platform system. The integrated online environment monitoring system includes a temperature and humidity monitoring module, a safety status module and an equipment status module; The temperature and humidity monitoring module is used to monitor the temperature and humidity data in the power distribution room and transmit it to the cloud platform system. The safety status module is used to monitor the safety status of the equipment in the power distribution room and transmit it to the cloud platform system. The equipment status module is used to monitor the status information of the equipment in the power distribution room and transmit it to the cloud platform system. The cloud platform system is used to receive the temperature and humidity, safety status and equipment status information of the power distribution room, and connect to the external network for online monitoring; Online monitoring is carried out through the cloud platform system, and the temperature, humidity, safety status and equipment status of the equipment in the distribution room are monitored in real time through the comprehensive environmental online monitoring system. When problems occur in the distribution room equipment, they can be discovered accurately and promptly, which facilitates the maintenance of the distribution room equipment.

[0016] A threaded block 26 is fixed to the right side of the inner wall of the chamber 2, a threaded hole is arranged in the middle of the threaded block 26, and a screw rod 261 is threadedly connected in the threaded hole, a rotating shaft 262 is fixed above the screw rod 261, a toothed disc 263 is fixed at the upper end of the rotating shaft 262, a sector tooth 221 is fixed to the outer side of the output shaft 22, the sector tooth 221 and the toothed disc 263 are meshed with each other, and a pressure plate 264 is fixed to the outer side of the rotating shaft 262; A hole is provided above the air pressure chamber 23, and a limit rod 233 is slidably connected in the hole, a ring tube 234 is fixed to the upper end of the limit rod 233, an elastic spring 235 is fixed between the bottom of the ring tube 234 and the upper surface of the air pressure chamber 23, and the elastic spring 235 is sleeved on the outer side of the limit rod 233. When the limit rod 233 and the magnetic plate 231 are in the initial state, the bottom end of the limit rod 233 contacts the upper surface of the magnetic plate 231; The rotation of the output shaft 22 drives the sector teeth 221 to rotate, and the sector teeth 221 drives the toothed disc 263 to rotate slightly through meshing, and the toothed disc 263 drives the screw 261 to rotate through the rotating shaft 262, and the screw 261 moves downward while rotating through the threaded hole of the threaded block 26, and the rotating shaft 262 drives the pressure plate 264 to move downward while rotating, so that the pressure plate 264 contacts the upper end of the annular tube 234, presses the annular tube 234, and the annular tube 234 drives the limiting rod 233 to move downward, and the elastic spring 235 is deformed by force, and the lower end of the limiting rod 233 contacts and squeezes the upper surface of the magnetic plate 231, so that the magnetic plate 231 is limited when it is reset; Thus, as the elastic expansion joint 25 is gradually extended, the monitoring range of the environmental monitor 1 increases. At this time, the magnetic plate 231 is limited so that less gas is extracted after resetting, and the amount of gas subsequently injected into the elastic expansion joint 25 is less, so that the length of the elastic expansion joint 25 extended each time becomes shorter and shorter. When the monitoring range increases, it is in a state of gradual and slow increase, thereby preventing a substantial increase in the monitoring coverage area from resulting in insufficient monitoring of the distribution room equipment and avoiding incomplete monitoring. The further outward the environmental monitor 1 is, the smaller the monitoring coverage area increases, so that it can play a role in comprehensive monitoring.

[0017] The number of teeth of the sector teeth 221 is one tenth of the number of teeth of the toothed disc 263, that is, when the sector teeth 221 rotates one circle, the toothed disc 263 rotates thirty-six degrees; The thickness of the toothed disc 263 is five times the thickness of the sector teeth 221, and in the initial state of the toothed disc 263, the bottom of the toothed disc 263 is flush with the bottom of the sector teeth 221; By making the number of teeth of the sector teeth 221 one tenth of the number of teeth of the toothed disc 263, the electromagnetic device 232 can be started and closed once for each rotation of the motor 21, and the toothed disc 263 rotates slightly, so that the limit rod 233 moves a small distance when moving downward, and the limit of the magnetic plate 231 increases slowly. The further the environmental monitor 1 is moved outward, the smaller the increase in the monitoring coverage area is, which plays a role in enhancing the monitoring quality and makes the monitoring of the equipment in the power distribution room more comprehensive; At the same time, by setting the thickness of the toothed disc 263 to five times the thickness of the sector teeth 221, the screw rod 261 moves downward and drives the toothed disc 263 to move downward, and the toothed disc 263 will not be disengaged from the sector teeth 221, thereby avoiding transmission failure and preventing the subsequent failure to reset.

[0018] The bottom of the screw rod 261 is provided with a countersunk hole, and a slider 27 is slidably connected in the countersunk hole. An insert block 271 is fixed to the upper end of the slider 27. A slot 272 is provided at the top of the countersunk hole. The insert block 271 and the slot 272 fit each other. A square block 273 is fixed at the bottom of the insert block 271, a round rod 28 is installed on the bearing at the bottom of the inner wall of the chamber 2, a square groove 281 is provided on the upper surface of the round rod 28, the square block 273 is inserted into the square groove 281, a disc 282 is fixed at the bottom end of the round rod 28, and a push-pull rod 283 is fixed to the outer side of the bottom of the disc 282.

[0019] The outer bearing sleeve of the bottom of the connecting shaft 24 is connected with a collar 242, and the right side of the collar 242 is provided with limit holes at the front and rear, and the limit holes are slidably connected with guide blocks 243, and the left end of the elastic expansion joint 25 is fixed with two guide rods 251, and the two guide rods 251 are respectively fixed to the two guide blocks 243, and the upper end of the collar 242 is fixed with a swing rod 29, and the upper end of the swing rod 29 and the lower end of the push-pull rod 283 are both spherical, and after the disc 282 rotates, the push-pull rod 283 and the swing rod 29 are in contact with each other; When the screw rod 261 moves downward, it drives the square block 273 to move downward. At the same time, the square block 273 is in an active state and will not rotate due to the rotation of the screw rod 261. The square block 273 slides downward along the inner wall of the square groove 281 of the round rod 28 until it touches the bottom. At this time, the square block 273 is supported, so that its upper end drives the slider 27 to slide upward along the countersunk hole at the bottom of the screw rod 261. The slider 27 drives the insert block 271 to insert into the slot 272. At this time, the screw rod 261 drives the round rod 28 to rotate through the square block 273. At the same time, the elastic expansion joint 25 is about to extend to the limit position. The monitoring coverage of the environmental monitor 1 is large. At this time, the round rod 28 drives the disc 282 to rotate, thereby driving the push-pull rod 283 to rotate around the center of the disc 282. When the push-pull rod 283 After contacting the swing rod 29, the swing rod 29 drives the ring 242 to rotate, and the ring 242 drives the guide rod 251 to rotate around the center of the ring 242 through the guide block 243, thereby driving the elastic expansion joint 25 to rotate, and the elastic expansion joint 25 drives the environmental monitor 1 to rotate, and then the push-pull rod 283 is out of contact with the swing rod 29. At this time, the environmental monitor 1 is reset due to the influence of the center of gravity, so that the environmental monitor 1 makes a swinging movement. When the monitoring coverage is large, the monitoring can be more comprehensive. When monitoring a large range, the front and rear monitoring surfaces of the peripheral area can be increased, and the coverage area is larger. It can prevent insufficient monitoring from causing problems with the equipment to be discovered in time, avoid the inability to maintain the equipment with problems in time, and greatly improve the monitoring quality.

[0020] A length meter is provided inside the elastic expansion joint 25, and the length meter is connected to the external control valve signal. A length identification module is provided inside the length meter, and the length identification module is used to identify the extension length of the elastic expansion joint 25, and when the elastic expansion joint 25 is extended to the limit length, the signal controls the external control valve to open and close; The operation steps of the motor 21 and the electromagnetic device 232 are as follows: Step S1, the motor 21 rotates forward, and the electromagnetic device 232 is briefly turned on and off once each time the motor 21 rotates one circle; Step S2: After the length measuring instrument recognizes that the elastic expansion joint 25 is extended to the limit length, a signal is sent to control the external control valve to open, so that the gas in the elastic expansion joint 25 is discharged, and the elastic expansion joint 25 is elastically reset; Step S3, the motor 21 rotates in the reverse direction, and the electromagnetic device 232 is briefly opened and closed once each time the motor 21 rotates one circle, until the elastic expansion joint 25 is extended to the limit length, the external control valve is opened, and the elastic expansion joint 25 is reset again; Step S4, repeating steps S1 to S3; In this way, the equipment in the power distribution room is monitored from the inside out in a cyclic manner, the monitoring range is greatly increased, and the conditions of all equipment are fully monitored.
