Underground long-distance intelligent wireless lighting system for coal mine

Abstract

The invention discloses an underground long-distance intelligent wireless lighting system for a coal mine. The underground long-distance intelligent wireless lighting system comprises a main roadway wall, an alternating-current power supply, a primary side rectifying and high-frequency converting device, a primary side resonance compensating device, an energy transmitting guide rail coil, a hook,a power pick-up and conversion device and lighting equipment. The lighting system has the beneficial effects that the energy transmitting guide rail coil can be arranged at will according to the actual illumination area requirement; the power pick-up and conversion device and the lighting equipment can be placed at any position of the energy transmitting guide rail coil according to lighting requirements; the power pickup and conversion device and the lighting equipment can be moved, overhauled and replaced at will, the whole circuit does not need to be powered off, the power supply reliability is higher, risks are reduced, and meanwhile due to the fact that the energy transmitting guide rail coil is electrically isolated from the power pickup and conversion device, the lighting system hasthe advantages of being flexible in power supply, easy to control, high in safety and convenient to maintain.

Description

technical field [0001] The invention relates to a wireless charging system, in particular to a coal mine underground long-distance intelligent wireless lighting system, which belongs to the technical field of wireless charging.
