Description

Technical Field

[0003] For example, the Chinese invention patent (application number: CN202310657883.2) discloses a "charging pile fault diagnosis method, device, system and computer-readable storage medium".

At present, the fault monitoring of each unit module generally adopts a preset sampling monitoring or threshold judgment method. If a fault occurs, the charging pile will send the fault result to the charging pile interface or remote platform, but such a fault monitoring method is only a one-way reporting mode. For remote operation and maintenance personnel, they can only know that many devices have failed through the remote platform, but they cannot locate the fault of the charging pile through remote active inspection.

When the transmission mechanism 3 is working, the slider 204 and the slide groove 203 are coordinated to ensure that the pull rope 205 is always straight.

[0039] By providing the electrode sheet 209 and cooperating with the two groups of electric shocks spaced apart inside the electric shock slot 208, different alarm effects can be provided according to different situations.

[0040] Further, such as Figure 5 , Fig. 9 and Fig.10As shown, the transmission mechanism 3 includes a transmission box 301 arranged in the inner cavity of the charging pile 101, and gear shafts 308 are symmetrically arranged on both sides of the transmission box 301. A servo motor 309 is fixedly installed at the bottom of one group of gear shafts 308, and a pull rope 205 is wound around the bottom of the two groups of gear shafts 308. The servo motor 309 cooperates with the gear shaft 308 to push the transmission box 301 to move, and synchronously drives the pull rope 205 to wind and scale. A support frame 307 is fixedly installed at one end of the transmission box 301 away from the charging pile 101, and the support frame 307 is in a right angle shape, and the top of the support frame 307 is engaged with the clamping groove 105. A sensor component 106 is arranged at the other end of the transmission box 301, and the sensor component 106 is fixedly connected to the inner wall of the charging pile 101.

[0041] The sensor assembly 106 facilitates the detection of various data inside the charging pile 101 , and the transmission box 301 cooperates with the support frame 307 to facilitate the movement of the charging gun 102 .

[0042] Further, such as Figure 5 , Fig. 9 and Fig.10 As shown, both sides and one end of the transmission box 301 are provided with discharge grooves 302 in an array, and the discharge grooves 302 are meshed with the gear shaft 308. The discharge groove 302 at one end of the transmission box 301 matches the sensor component 106. A movable rod 303 is provided in the middle of the inner cavity of the transmission box 301. A fixed plate 304 is fixedly installed at one end of the movable rod 303 away from the support frame 307. The other end of the fixed plate 304 and both sides of the movable rod 303 are provided with sealing covers 306 in an array, and the sealing covers 306 are provided in an array. The cover 306 is connected to the discharge trough 302, and a fixed shaft 305 is provided through the other end of the movable rod 303. The fixed shaft 305 is connected to the internal spring of the movable rod 303, and the other end of the fixed shaft 305 is fixedly connected to the inner wall of the transmission box 301; when the sealing cover 306 is squeezed by the sensor component 106, it separates from the discharge trough 302. At the same time, the sealing cover 306 squeezes the movable rod 303, so that the sealing covers 306 at both ends of the movable rod 303 are synchronously separated from the discharge trough 302.

[0043] The sealing cover 306 cooperates with the discharge chute 302 to facilitate the transmission box 301 to penetrate, thereby achieving the fire extinguishing operation.

[0044] The use process of the charging pile fault diagnosis system and device provided by the present invention is as follows: First, the device is taken out and installed at an appropriate position. When charging is required, the servo motor 309 is started and drives the gear shaft 308 installed at its output end to rotate. At this time, the pull rope 205 wound under the gear shaft 308 is released when the gear shaft 308 rotates; The gear shaft 308 rotates continuously and drives the gear box 301 meshed therewith to move outward, thereby pushing the charging gun 102 outward through the gear box 301 and the support frame 307, until the charging gun 102 is separated from the mounting sleeve 103 and completely moved to the outside of the charging pile 101. At this time, the user holds the charging gun 102 and lifts it upward, and the charging gun 102 pushes the protective cloth 201 above it and the alarm 202 installed at both ends of the protective cloth 201, so that the charging gun 102 and the card slot 105 opened at the bottom are separated from the support frame 307. At this time, charging can be carried out. At the same time, the servo motor 309 is started in reverse to reset the gear box 301. During the charging process, if overvoltage or overcurrent occurs inside the charging pile 101, the servo motor 309 is started in reverse, and the transmission box 301 is driven to move toward the inside of the charging pile 101 until the sealing cover 306 at one end of the transmission box 301 contacts the sensor assembly 106. At this time, the servo motor 309 cooperates with the gear shaft 308 to wind the pull rope 205, thereby pulling the alarm 202 to rotate downward. At this time, the first group of electric shocks carried in the electric shock slot 208 contacts the electrode sheet 209, thereby connecting the alarm 202 and sounding an alarm. If the charging pile 101 overheats and catches fire during the charging process, repeat the above steps, and use the servo motor 309 to continuously drive the transmission box 301 to move into the charging pile 101, and make the sealing cover 306 at one end of the transmission box 301 continue to squeeze the sensor component 106 until the sensor component 106 squeezes the sealing cover 306 in contact with it into the transmission box 301. Synchronously, under the transmission of the movable rod 303 and the fixed plate 304, the sealing covers 306 on both sides of the transmission box 301 also fall off. At this time, the pressurized carbon tetrachloride filled in the transmission box 301 is ejected through the discharge trough 302, thereby realizing the fire extinguishing operation.
