Description

An alarm device for insufficient extension length of the insulating arm of the insulated bucket arm truck

technical field

The invention relates to an alarm device for insufficient extension length of an insulating arm of an insulating bucket arm vehicle.

Background technique

At present, a large number of 10kV distribution network live work has been carried out in the power system. Among them, the insulated arm truck is a very important operation platform for distribution network live work, and more than 90% of the operations must be realized by the insulated arm truck. The insulated bucket arm truck sends the workers to the overhead line, and extends the insulating arm to a certain length, and keeps the workers insulated from the ground through the insulating arm to ensure the safety of the workers. Therefore, the insulation arm is the main insulation during the live work. According to the electric safety regulations, the live work of 10kV distribution network needs to extend the insulation arm to an effective length of at least 1m, that is, the distance between the crank arm and the metal telescopic arm must be at least 1m distance, so as to maintain effective insulation to the ground. However, during the operation process, the operators often ignore this requirement, especially in the phase change operation and near-side phase operation, the length of the insulating arm is often less than 1m, which affects the safety of the operation. Therefore, in the live work of 10kV distribution network, it is of great practical significance to design a warning device for insufficient extension length of the insulating arm of the insulating bucket truck for live work, which can improve the safety of the work and remind the operators in time.

The first supporting foot 11 can be fixed to the metal telescopic arm by means of locking screws, or can also be fixed by means of bonding, which is not limited thereto.

The light control alarm is installed on the end of the insulating arm away from the metal telescopic arm. The light control alarm includes a box body 20, a battery 21, a photoresistor 22, a control circuit board 23 and a buzzer 24, a battery 21, and a control circuit board 23 and the buzzer 24 are all installed in the box body 20, the light emitted by the directional light emitter 10 is aimed at the photoresistor 22, the battery 21 is electrically connected with the control circuit board 23, the buzzer 24, and the photoresistor 22, when the directional light emitter When the distance between the device 10 and the photoresistor 22 is less than a preset value, the buzzer 24 sends out an alarm sound. In this embodiment, the preset distance between the directional light emitter 10 and the photoresistor 22 is set to 1 m. The preset value can be adjusted according to actual needs.

In this embodiment, a through hole 26 is opened on the side of the box body 20 , and the photoresistor 22 corresponds to the through hole 26 to ensure that the photoresistor 22 can receive the light emitted by the directional light emitter 10 .
