Pneumatic anti-bird thorn

Abstract

The invention discloses a wind-driven anti-bird thorn, comprising a fixed base, the fixed base is provided with a shield, the top of the shield is provided with a fixed shaft, and the fixed shaft is provided with a sliding ball seat for rotation, A plurality of needles are arranged above the sliding ball seat, and the needles are located above the shield to form an inverted umbrella structure, and a dynamic main shaft is located in the shield below the sliding ball seat, and the lower end of the dynamic main shaft is connected with The swing weight is provided with a stress spring between the shield and the swing weight, and the stress spring is sleeved on the dynamic main shaft. When a bird touches the anti-bird thorn, it will shake by itself when it is stressed, so that the bird cannot stay on the insulator, making it impossible to defecate and build a nest on the tower pole, which greatly improves the performance of the anti-bird thorn and has high reliability. , The installation is simple and easy to maintain, and it solves the safety problems of transmission lines mainly caused by guano flashover and bird's nest short-circuit faults.

Description

technical field [0001] The invention relates to an anti-bird thorn, in particular to a pneumatic anti-bird thorn. Background technique [0002] At present, most of the existing anti-bird thorns are fixed structures, which are fixedly installed on the iron cross-arm, and are used to drive away birds on the tower pole of the transmission line, prevent birds from nesting and staying on the top of the insulator, and solve the problem of flashing with bird droppings. To protect the normal operation of transmission and distribution lines, the main transmission line operation safety issues are network and bird's nest short-circuit faults. The existing anti-bird thorns have a fixed protection range, and the protection range is small. It is necessary to install more than one to achieve a good protective effect, which increases the cost; moreover, the old-fashioned anti-bird thorns are mostly made of steel strands and galvanized iron wires. After long-term use, The puncture needle is...

Problems solved by technology

The existing anti-bird thorns have a fixed protection range, and the protection range is small. It is necessary to install more than one to achieve a good protective effect, which increases the cost; moreover, the old-fashioned anti-bird thorns are mostly made of steel strands and galvanized iron wires. After long-term use, The puncture needle is easy to deform, which affects the protective effect; because the anti-bird thorn is an unfolded structure, it is not conducive to inspection and maintenance after being installed on the tower pole, resulting in new safety hazards, increasing labor intensity, and causing certain troubles for maintenance personnel
