Self-generating device for freight train safety monitoring system

Abstract

The invention relates to a self-generating device for a freight train safety monitoring system, and aims at converting mechanical energy of axle rotation into electric energy capable of supplying electricity to a monitoring device, so that active monitoring of the safe driving state of a freight train becomes feasible. The self-generating device comprises an axle and a wheel, wherein the wheel is arranged on the axle; a bogie side frame is arranged at the outer side of the axle; a dustproof plate seat groove on the axle is arranged between the inner side of the bogie side frame and the outer rim of the wheel; a side frame groove is formed in the end surface, toward the running front, of the bogie side frame; a wedge block of which the size is consistent with the internal shape of the groove is embedded into the side frame groove close to the lower part; the outside of the wedge block is fixed to the bogie side frame by a hoop I; a rotating shaft-type generator is fixed at the outer side of the wedge block through a hoop II; a rotating shaft of the generator extends towards the wheel direction; a generator driving wheel is arranged at the end part of the rotating shaft; a transmission belt is connected between the generator driving wheel and the dustproof plate seat groove; and an AC power output by the rotating shaft-type generator is stored into a power storage unit after being processed by a circuit unit.

Description

technical field [0001] The invention relates to a self-generating device used in a freight train safety monitoring system. It is suitable for providing electric energy for the operation safety monitoring system of freight trains. Background technique [0002] As a freight train with good economic benefits in the railway transportation system, it has been facing a technical problem for a long time, that is, it is impossible to monitor the real-time status of the train in operation. The existing monitoring means are to install infrared temperature monitoring devices on the side of the railway, and when the train passes by, the corresponding irradiation is passively measured. However, this monitoring method lacks real-time and missed detection. Although the railway department has invested a lot of money to install and maintain these devices, it has not really achieved the desired safety requirements. On the other hand, the truck system cannot increase the speed on a large sca...

Problems solved by technology

The solutions to the power generation problem in the existing literature include: 1) "Broad-gauge bogie with power generation device 200620034961.5" by China South Locomotive Group Meishan Vehicle Factory; 2) "Railway Express Freight Vehicle Axle End Power Supply Device 201210561264.5" by Tongji University; 3) Zhang Jian's "Railway Freight Car Safety Monitoring System 201110326854.5", 1) is unreasonable in that an extended bracket is installed on the frame of the bogie side frame, which increases the volume occupied by the bogie to the outside space; 2) and 3) the problem is that the generator body is installed on the position of the rotating shaft sleeve and the front cover, which will affect the daily maintenance work of the bogie axle, and these problems are extremely unfavorable to driving safety
