High-voltage power line crash site alarm apparatus

Abstract

The present invention discloses a high-voltage power line crash site alarm apparatus, which is an alarm apparatus sleeved on a cable, slides along the cable when the cable is broken, and falls onto the ground to give a smoke alarm. The protecting shell is hemispheric. Two protecting shells are clipped to form a whole ball housing. The protecting shell is made of a rubber material. A through hole is opened on the whole ball housing. The through hole runs through the whole ball housing. Multiple circles of roll balls are rotatably disposed on an inner wall of the through hole. One circle of rolls ball consists of at least eight roll balls. Two cigarette lighting grooves are opened on the protecting shell. A position giving groove is opened on a side of an inner part of the cigarette lightinggroove, and one end of the position giving groove extends out of the cigarette lighting groove. Two copper sheets are fixedly disposed inside the position giving groove. Sliding chutes are opened onthe bottom and the top of the cigarette lighting groove. The sliding chute is closely adjacent to the side of the inner part of the cigarette lighting groove. A sliding block is disposed inside the cigarette lighting groove, and an upper side and a lower side of the sliding block are slidably disposed inside the sliding chute.

Description

technical field [0001] The invention relates to an alarm for the drop point of a high-voltage line, which relates to an alarm for the drop point of a high-voltage line, and belongs to the field of electric equipment. In particular, it relates to an alarm device which is sheathed on a cable and slides along the cable and falls on the ground for smoke alarm when the cable breaks. Background technique [0002] High-voltage wires are generally used for long-distance power transmission, because the loss of transmission is small after the voltage is increased, so the high-voltage lines between cities are generally above 100,000 volts, and those within the city will also be above 10,000 volts. When the wires are broken by external factors When the wire falls on the ground, it is easy to cause electric shock to nearby personnel and endanger its life safety. It will cause it to stray into the leakage area of ​​the incoming wire and cause casualties. Especially for some areas that ar...

Problems solved by technology

[0002] High-voltage wires are generally used for long-distance power transmission, because the loss of transmission is small after the voltage is increased, so the high-voltage lines between cities are generally above 100,000 volts, and those within the city will also be above 10,000 volts. When the wires are broken by external factors When the wire falls on the ground, it is easy to cause electric shock to nearby personnel and endanger its life safety. It will cause it to stray into the leakage area of ​​the incoming wire and cause casualties. Especially for some areas that are easily affected by the external environment and have a high frequency of high-voltage wire breakage, it is necessary to set up a high-voltage wire disconnection warning. The structure of the falling device is complicated, and the overall erection and installation are complicated, which consumes time and manpower

[0003] The notification number CN108879546A discloses a high-voltage wire fall prevention device, which includes electric wires, which are hung on the upper part of the pole, and also includes: pulley blocks hanging on the poles, tension ropes connected between the pulley blocks, and tension ropes connected in series. The breaker, the tension rope, and the breaker are respectively connected with traction ropes. At the same time, between the poles and under the wires, there is a net bag, and a storage box is set under the pulley block. The overall structure of the device is complex and bulky. The installation is cumbersome, troublesome and time-consuming
