Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mine electric locomotive, in particular to an unmanned mine electric locomotive. BACKGROUND

[0002] The unmanned mine electric locomotive is a highly advanced mine equipment, which aims to realize the automation of mine transportation and logistics. This electric locomotive is equipped with advanced automation technology, such as sensors, cameras, laser radars and GPS systems, in order to intelligently navigate and operate in the mine environment. The main goal of these unmanned electric locomotives is to improve the efficiency, safety and sustainability of mine operations. They can autonomously perform tasks such as transporting ore, rock and other materials without human intervention. This not only reduces the risk of personnel in dangerous environments, but also reduces the possibility of accidents and operational errors.

[0003] Currently, the underground mine environment has high temperature and high humidity, and is in a state of 30-40°C and humidity greater than 85% for a long time. At the same time, a large amount of dust is generated during ore mining and transportation, which can float and diffuse into the machine box. In such an environment, there are serious problems of poor heat dissipation and dust accumulation inside the electrical machine box:

[0004] 1) The air with high temperature and humidity reduces the heat dissipation efficiency inside the machine box, and the electrical components are in a long-term overheated environment, which leads to the decrease of insulation performance and the increase of conduction resistance, making the motor and electrical control components more prone to aging and failure;

[0005] 2) A large amount of fine dust accumulates on the surface of electrical components, increases the insulation distance, and also gathers in the gaps between the heat sinks to hinder heat dissipation, further deteriorating the heat dissipation environment, and the dust can also directly cause short circuit of electrical components, poor contact of contacts and other faults.

[0006] For example, when the mine train is formed, the locomotive is parked in the bare mine environment, and the machine box of the locomotive is directly exposed to high temperature and humidity and ore dust. After a period of time, the insulation and heat dissipation performance of the electrical components inside the machine box will be significantly deteriorated, and faults such as component overheating and insulation resistance decrease will occur, which may cause damage to the main circuit of the locomotive, directly affecting the reliability and service life of the locomotive.

[0007] Based on this, the present application designs an unmanned mine electric locomotive to solve the above-mentioned problems. SUMMARY
