Description

Technical Field

[0002] The distribution cabinet is divided into power distribution cabinet, lighting distribution cabinet and metering cabinet. It is the final equipment of the distribution system. The distribution cabinet is a general term for the motor control center. The solar distribution cabinet can use solar energy for power conversion and power supply, effectively saving a lot of resources.

[0003] Due to its characteristics, the distribution cabinet needs to be in a place where it can be exposed to sunlight for a long time. However, the existing heat dissipation design of the distribution cabinet only dissipates heat by setting ventilation holes, which has poor heat dissipation effect. In addition, the solar distribution cabinet needs to be exposed to sunlight for a long time. It is easy to cause the internal temperature of the distribution cabinet to be too high, causing the electronic components inside it to stop working. If the power is taken from the inside of the distribution cabinet, it does not meet the concept of energy saving and environmental protection. In the rainy summer period, there is also the risk of water ingress and leakage. Utility Model Content

The rocker arm 209 is fixedly connected to a connecting arm 211 via a connecting rod 210 hinged thereto. The rotation of the servo 208 drives the rocker arm 209 to swing, thereby driving the connecting arm 211 via the connecting rod 210, thereby realizing the adjustment of the pitch angle of the solar panel 207.

[0024] In the technical solution of the present utility model, two coaxial guide blocks 101 are fixedly connected inside the box body 1; the guide blocks 101 are coaxially slidably connected with guide rods 102, so that the guide rods 102 can slide freely and coaxially inside the two guide blocks 101, and prevent self-locking and jamming.

[0030] When the device starts to be used, the controller 108 obtains electric energy from the battery 107 to drive the rotating motor 204 and the servo 208 to operate, thereby achieving the best rotation angle and pitch angle of the solar panel 207 and maintaining the best photosensitivity angle with the sun at all times. The electric energy generated by the solar panel 207 is stored in the battery 107; when the temperature inside the box 1 is too high, the controller 108 sends a signal, and the battery 107 drives the cooling fan 110 to operate to dissipate heat inside the box 1; when water enters the box 1, the float 103 floats up and triggers the position switch 104 to operate through the guide rod 102, so that the controller 108 receives a signal, thereby cutting off the circuit of the distribution cabinet to prevent leakage and increase the safety of the equipment.
