On the inner ring of the bearing, and then realize the rotational connection of the movable rod and the movable plate, between the fixed plate and the movable plate, there is a cabinet locking spring 33 nested outside the movable rod, in order to realize the connection between the movable rod and the movable plate Move synchronously, be fixed with positioning bar 35 on the movable bar of mobile plate left and right sides. The cabinet body locking rod 3 is fixed on the leftmost end of the movable rod, as shown in Figure 8, the cabinet body locking rod can be hidden in the mounting block, and an extension rod 36 is fixed on the rightmost end of the movable rod, which is locked in the cabinet body. A coil spring 32 is arranged between the rod and the moving plate, and when the movable rod is rotated, the active force of the coil spring can be overcome to make the cabinet body locking rod rotate. After the movable rod is released, the cabinet body locking rod and the The movable lever resets. In the natural state, under the action of the cabinet locking spring, the cabinet locking rod stretches out from the base, and when the movable rod is pulled to the right, the cabinet locking spring can be compressed, and a retaining rod 34 is fixed on the movable rod. After the right passes through the fixed plate, turn the movable rod (the fixed plate is provided with a retaining rod hole for the retaining rod to pass through), and the movable rod and the fixed plate can be relatively stationary under the action of the retaining rod. At this time, the retaining rod and the fixed The baffle rod holes on the plate are staggered from each other.

In order to drive the rotation of the extension rod, as shown in Figure 6 and Figure 7, an ear plate 361 is provided along the radial direction of the extension rod on the outer wall of the extension rod, and a joystick 37 is installed on the hinge 38 on the ear plate. After axially rotating the joystick so that the joystick is perpendicular to the extension rod, the joystick is rotated radially along the extension rod to drive the rotation of the movable rod. As shown in Figure 4, a rod groove 151 and a transverse groove 153 arranged along the length direction of the installation block are provided on the front side wall of the installation block, and a second groove 153 arranged along the height direction of the installation block is also provided on the front side wall of the installation block. A longitudinal groove 152 and a second longitudinal groove 154, the transverse groove is located between the first and second longitudinal grooves and the transverse groove communicates with the first and second longitudinal grooves.

The right side of the base is provided with a blind hole, and an inner cover 4 is fixed in the blind hole, and a locking block 41 is arranged in the inner cover, the locking block is a cube or a cylinder structure, and a locking block is provided on the right end surface of the locking block.

In order to allow remote monitoring personnel to monitor the low-voltage power distribution cabinet in real time, when the temperature inside the cabinet sensed by the temperature sensor exceeds a certain value, the controller sends a message to the monitoring room through GSM to inform the monitoring personnel. The temperature sensor, the controller and the second indicator light constitute a high temperature alarm mechanism.

In order to monitor the fire, a smoke sensor is provided on the top of the cabinet, the smoke sensor is connected to the controller signal, the controller is connected to the current loop where the third indicator light 183 is located and controls the working state of the third indicator light, when the smoke sensor After sensing the smoke information in the cabinet, the controller controls the third indicator light to light up. In order to allow remote monitoring personnel to monitor the low-voltage power distribution cabinet in real time, when the smoke sensor senses the smoke in the cabinet, the controller sends a message to the monitoring room through GSM to inform the monitoring personnel. Smoke sensor, controller and third indicator light constitute the fire alarm mechanism.

In order to facilitate the monitoring personnel to know the problems existing in the cabinet through observation, the first, second and third indicator lights are arranged on the cabinet door, and the first, second and third indicator lights can emit light of different colors. for easy distinction. According to the lights of different colors emitted by the first, second and third indicator lights, the problems existing in the cabinet can be distinguished.

The fire in the cabinet is monitored by the fire alarm mechanism, and an alarm can be sent to the monitoring room when a fire occurs; the abnormal temperature in the cabinet is monitored by the high temperature alarm mechanism, and an alarm can be sent to the monitoring room when the temperature is abnormal; the monitoring cabinet can be destroyed by external force When the cabinet is damaged, an alarm can be sent to the monitoring room.

As shown in Fig. 19 and Fig. 20, an infrared emitter 5 and an infrared receiver 51 arranged up and down are also arranged on the inner wall of the cabinet, and the infrared emitter 5 and the infrared receiver 51 are many pairs, and the infrared emitter emits The infrared rays 52 can be received by the infrared receiver. After a certain period of time, the infrared transmitter emits infrared rays, and the infrared receiver sends a signal to the controller after receiving the infrared rays. As shown in Figure 21, when the cabinet is damaged, the side wall of the cabinet becomes uneven, and the infrared emitted by the infrared transmitter cannot be received by the infrared receiver. At this time, the controller cannot receive the infrared receiver for a long time. After the incoming signal, the controller will control the first indicator light to light up. At this time, the controller also sends a message to the monitoring room through GSM.
