The detection device is arranged on the top of the inner wall of the shell, and the detection device is electrically connected to the servo motor. The reversal of the I-shaped wheel will drive the fixed arc rod to rotate, and the rotation of the fixed arc rod will drive the power cord to stretch, so that in the face of extreme weather, the output end of the servo motor will rotate slightly in the opposite direction and stretch the tightened power cord.

[0007] According to the above technical solution, a No. 1 spring is arranged between the sliding column and the housing, the power line contacts the sliding column, and the sliding column is driven to reset by the No. 1 spring.

[0008] According to the above technical scheme, the sealing device includes: a transmission triangle, a baffle, a square block, a transmission vertical rod and an elastic telescopic rod. A vent is opened on the surface of the shell. The square block is fixedly installed on the top of the inner wall of the shell.

The transmission triangle is fixedly installed on the side where the transmission vertical rod is close to each other. The baffle is rotatably installed on the inner wall of the shell. The two ends of the baffle are rotatably installed on the side where the transmission vertical rod is close to each other. The fixed end of the elastic telescopic rod is rotatably installed on the surface of the I-wheel. The free end of the elastic telescopic rod is slidably installed on the inner wall of the shell. The movement of the transmission triangle will drive the transmission vertical rod to move to the top. The movement of the transmission vertical rod will drive the baffle to rotate in the direction of the vent. The rotation of the baffle will block the vent.

The transmission round rod is fixedly installed on a side of the square plate close to the reset plate. The movement of the transmission round rod will drive the square plate to move. After the square plate moves, it no longer contacts the L-shaped rod, so that the protective door can be opened through a special unlocking method.

[0013] According to the above technical solution, the reset plate contacts the transmission round rod, and a second spring is arranged between the rotating long rod and the protective door. The second spring drives the rotating long rod to reset.

[0014] The present invention provides a combined reactive power compensation controller chassis, which has the following beneficial effects: (1) The invention, by rotating the fixed arc rod, drives the power cord to rotate and reel, thereby preventing multiple power cords from being randomly placed inside the housing, resulting in air inside the housing being unable to circulate, causing the device inside the housing to be unable to dissipate effective heat, thereby improving the protection effect of the device. After the limit baffle contacts the limit block, the limit block can no longer rotate, making the I-shaped wheel unable to rotate. After the power cord is completely reeled, the I-shaped wheel can no longer reel, thereby preventing excessive reeling from causing the connection between the power cord and the distribution cabinet or power supply device to be disconnected, resulting in the device being unable to work normally, thereby improving the stability of the device during operation. The output end of the servo motor will rotate slightly in the opposite direction and stretch the tightened power cord, thereby preventing the entire device from shaking in extreme weather, causing the power cord to be disconnected in the tightened state, thereby further improving the protection effect of the device.

[0015] (2) In the present invention, the movement of the transmission vertical rod drives the baffle to rotate in the direction of the vent. The rotation of the baffle blocks the vent to prevent rainwater or impurities from flowing back into the shell in extreme weather, causing the shell to no longer be insulated and causing the device to discharge or leak electricity, thereby improving the safety of the device. The movement of the sealing plate will contact the baffle and block and seal the contact point between the baffle and the vent, further improving the sealing effect of the baffle.

[0016] (3) The invention prevents the protective door from being opened by preventing the square plate from rotating outward. In extreme weather conditions, the protective door is doubly limited to prevent the protective door from being opened and causing the internal device of the housing to be exposed to rain and damaged. After the square plate moves, it no longer contacts the L-shaped rod, so that the protective door can be opened. A special unlocking method allows the protective door to be opened under special circumstances. The protective door cannot be opened by a single pull or a single rotation, thereby improving the practicality of the device. BRIEF DESCRIPTION OF THE DRAWINGS
