Description

TECHNICAL FIELD

[0001] The utility model relates to high branch saw technical field, concretely is a safe and efficient electric insulation high branch saw. BACKGROUND

[0002] In the operation and maintenance of power transmission and distribution lines, vehicles cannot enter individual sections, and some eucalyptus, cluster flowers, and paulownia trees often grow in the line protection area. These trees grow very quickly, with an average annual growth height of more than three meters, posing a great hidden danger to the safe operation of high-voltage lines. If not cut down in time, it may cause personal injury or equipment tripping accidents during strong winds or thunderstorms. In the complex environment of the wild, it is easy to touch the high-voltage line above the branches during the use of ordinary high branch saws, and the low-voltage insulation layer on the high branch saw will be punctured, causing casualties.

[0003] The existing device mainly extends the height of the electric saw through a threaded fixing section. The existing technology is similar to an electric high branch saw, and the structure of the patent number CN208425236U includes an electric saw machine, a telescopic rod, and a Bluetooth switch. The electric saw machine includes a gear, a motor, and a battery. The electric saw machine is detachably connected to the telescopic rod. The telescopic rod includes a metal inner rod and an outer rod. The metal inner rod is sleeved in the outer rod. The metal inner rod is detachably connected to the electric saw machine. The outer rod includes a metal outer rod at the top end of the outer rod and a high-voltage resistant insulation outer rod at the lower end of the outer rod. A high-voltage alarm is provided on the metal outer rod. A Bluetooth signal receiving end is provided on the motor. The advantage is that the high-voltage alarm can alert the operator of the distance between the electric saw machine and the high-voltage line to ensure the safety of the high-voltage line. However, the device still has room for optimization.

[0004] The existing device mainly controls the electric saw to cut off the branches by manually holding the extension rod, making it difficult for some devices to control the inclination angle of the electric saw, thus making it inconvenient for the electric saw to cut off the branches. At the same time, some devices are mainly composed of multiple telescopic rods, making it difficult for some devices to adjust the height of the electric saw according to the position of the branches, thus making it inconvenient to cut off branches of different heights, reducing the working efficiency and practicality of the device. Therefore, in order to solve the above problems, a safe and efficient electric insulation high branch saw is proposed. UTILITY MODEL CONTENTS
