The force-bearing mechanism is aligned with the air switch to make the force-bearing plate contact the switch of the air switch. If the switch has fallen, the force-bearing mechanism can move down, and the elasticity of the spring is small. When the air switch trips, the switch will fall in an instant. At this time, due to the large force of the switch falling, the steel ball can be separated from the sleeve, and then the force-bearing plate and the plug rod can move down. When the plug rod moves down, the plug rod can push the two connecting rods to separate the two dial plates, and when the two dial plates are separated, the detection plate can be driven down, without any No matter which switch trips rapidly, the detection plate can be lowered, while a slow lowering of the force-bearing mechanism will not cause the detection plate to drop. When the detection plate drops, the conductive plate A and the conductive plate B can be separated and the power can be cut off, which can have an alarm effect. When sparks or explosions occur in the air switch, the detection frame can be impacted. The detection frame can be separated from the detection plate when under force. In a normal state, the detection frame and the detection plate are in a circuit-connected state. When separated, the circuit is disconnected, which has the effect of detecting the distribution cabinet. This solves the problem that the existing sensors in the prior art generally need to use electricity, cannot send signals when the power is off, and have a large degree of restrictions on use.

[0015] 2. The safety detection device for power distribution is provided with a slot, and the slot can connect two detection boards. When facing a distribution cabinet with more air switches, a longer distance can be detected through the connection of the detection boards.

[0016] 3. The safety detection device for power distribution is provided with an annular groove which can fix the steel ball. However, due to the smoothness of the surface of the steel ball, the steel ball can be separated from the annular groove when subjected to a sharp force.

[0017] 4. The safety detection device for power distribution can achieve better transmission effect by setting a force-bearing plate with an arc-shaped groove, and the arc-shaped groove can be adapted to the air switch. BRIEF DESCRIPTION OF THE DRAWINGS
