Loosening-preventing and automatic-fastening device of connection bolts for combination and fixation of storage batteries

Abstract

The invention discloses a loosening-preventing and automatic-fastening device of connection bolts for combination and fixation of storage batteries. According to the loosening-preventing and automatic-fastening device, a ratchet sleeve is arranged on the front side of a fixed connection handle, a ratchet is arranged inside the ratchet sleeve, fixed inner teeth are arranged on the inner side of the ratchet, ratchet teeth are arranged on the outer circumference of the ratchet, receding stopping grooves are formed in the inner side of the ratchet sleeve, receding stopping springs are arranged in the receding stopping grooves, a receding stopping pin is arranged on the front side of each receding stopping spring, a fixed clamping base is arranged on the rear side of the fixed connection handle, and a tension spring is arranged on the upper side of the fixed clamping base. When copper connection bars of a storage battery pack are twisted slightly, and alternatively vibration is produced due to environmental factors, the ratchet teeth prevent the bolts from moving in the loosening direction under the action of the receding stopping pins, the bolts are pushed to rotate in the fastening direction, and the function of automatically fastening the bolts is achieved.

Description

technical field [0001] The invention relates to a connecting bolt for fixing a battery pack, in particular to an automatic fastening device for fixing the connecting bolt of a battery pack. Background technique [0002] At present, the market competition is fierce, prompting the rapid expansion of the scale of the communication network. The communication network computer rooms, IDC communication computer rooms, transmission convergence computer rooms, and base station computer rooms are "blossoming everywhere", and there is a trend of stronger expansion. [0003] The most basic requirement of communication network service is continuous and uninterrupted service. The uninterrupted service of the communication network service is based on the uninterrupted power supply of the communication network equipment system. [0004] The uninterrupted power supply of the current network communication network equipment system mainly consists of a DC uninterrupted power supply system and ...

AI Technical Summary

Problems solved by technology

[0011] (2) Increased network operating costs:

According to incomplete statistics, the premature scrapping of batteries will cause operators to increase network operating costs by nearly one billion yuan each year.

[0015] (3) Increase the cost of environmental pollution control

[0016] Battery packs are generally scrapped ahead of time. During the process of recycling and reprocessing battery packs by battery manufacturers, serious lead emissions are formed, which increases local environmental pollution and increases the cost of environmental pollution control.

[0017] (4) There are fire hazards

[0018] The fastening bolts are loose, the connection between the copper bar and the battery pole is poor, and contact resistance is formed at the connection part

During the high-current charging and discharging process of the battery, the heat accumulation at the connection part will cause the battery to melt, short-circuit and catch fire.
