Distribution box door opening and closing mechanism based on alternating-current distribution device

Abstract

The invention relates to the technical field of alternating-current power distribution devices, and discloses a power distribution box door opening and closing mechanism based on an alternating-current power distribution device. The mechanism comprises a box body; the left side of the box body is fixedly connected with a connecting block. According to the distribution box door opening and closingmechanism based on the alternating-current distribution device, when a gear rotates counterclockwise, at the moment, a clamping block moves downwards under the powerful action of teeth on the clampingblock, the gear can rotate anticlockwise; when the gear rotates clockwise, the clamping block can generate resistance to the teeth, so that the teeth cannot rotate, the gear cannot rotate clockwise;and therefore, the effect of controlling the rotating direction of the gear is achieved. When wind power acts on an opened box door, the box door can rotate anticlockwise through the wind power, a clamping rod can drive the gear to rotate clockwise, the box door cannot be closed through the wind power due to the fact that the gear cannot rotate clockwise, and therefore the effect that closing of the box door cannot be affected by the wind power when the box door is opened and closed at any angle is achieved.

Description

technical field [0001] The invention relates to the technical field of AC power distribution devices, in particular to a switch door mechanism for a distribution box based on an AC power distribution device. Background technique [0002] The AC power distribution device is used to connect the power supply, transformer, converter equipment and other loads, and monitor and protect the power supply system. The control functions of the operation mode, such as protection, measurement, alarm and power factor compensation, etc. [0003] The distribution box is used to connect the power supply, transformer, converter equipment and other loads. It is a very important AC power distribution device. When the outdoor distribution box is in the process of circuit inspection, its door will be affected by the wind, and it needs to be manually However, in the case of circuit leakage, holding the box door with hands is likely to cause electric shock hazards, and during the internal operation...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a distribution box door opening and closing mechanism based on an AC power distribution device, which has the advantage that the box door will not be closed due to the influence of wind force at any angle of opening and closing, and solves the problem that the outdoor distribution box During the circuit inspection process, the box door will be affected by the wind force and needs to be supported by hand. However, in the case of circuit leakage, holding the box door with hands is likely to cause electric shock hazards. The frequent shutdown will bring great inconvenience to the operator
