Wireless power supply system for mining electric locomotive

Abstract

The invention discloses a wireless power supply system for a mining electric locomotive. The wireless power supply system comprises a network source, a primary energy conversion module connected with the network source, an energy receiving device mounted on the mining electric locomotive, and an energy conversion and control module, wherein an electromagnetic coupling resonance type electric energy transmission mode is adopted between the primary energy conversion module and the mining electric locomotive; the primary energy conversion module is a primary coil side; the energy receiving device of the mining electric locomotive and the energy conversion and control module form a secondary coil side; the energy receiving device is used for receiving electric energy, and the electric energy is converted by the energy conversion and control module into an electric energy form available for the mining electric locomotive; a coupling coil on the primary coil side adopts a sectional type power supply guide rail mode; a power supply guide rail is laid below a running rail of the mining electric locomotive; a coupling coil on the secondary coil side is the energy receiving device. According to the wireless power supply system for the mining electric locomotive, multiple problems of a conventional storage battery type mining electric locomotive during application are solved, and the duration capacity, the safety and the reliability of the mining electric locomotive can be improved.

Description

technical field [0001] The invention relates to the technical field of wireless power supply, in particular to a wireless power supply system for mining electric locomotives. Background technique [0002] Mining battery electric locomotive is an auxiliary transportation equipment commonly used in mines in my country. The electric locomotive transportation system mainly includes rails, mine cars, traction equipment and auxiliary mechanical equipment, etc., and is often composed of ore loading equipment, belt conveyors or trackless transportation equipment. efficient transport system. According to the different nature of the power supply, mining electric locomotives include DC electric locomotives and AC electric electric locomotives. At present, battery DC electric locomotives are most widely used in coal mines. The current mine electric locomotive is generally equipped with 2 to 3 sets of lead-acid battery packs, each weighing about 1 ton. After the battery pack on the elec...

AI Technical Summary

Problems solved by technology

Due to the low energy density, short service life and high maintenance cost of lead-acid batteries, the operating efficiency of electric locomotives is low, and the transportation costs are high. Moreover, lead-acid batteries have high cost and high pollution problems, and discarded batteries will also cause serious pollution to the environment.

In addition, the power supply module and driving equipment of the mine electric locomotive are designed separately, occupying a large space of the electric locomotive, and the stability and safety are not high
