Abstract

The invention discloses a mine intrinsic safety type portable detection robot body driving device. The mine intrinsic safety type portable detection robot body driving device comprises an intrinsic safety electric source, a load matching circuit and a mine intrinsic safety type portable detection robot body motor which are connected in sequence, wherein the intrinsic safety electric source comprises a battery set protection circuit, a series battery set, a soft switch, a guard grating and a double voltage stabilizing circuit which are connected in series sequentially. The mine intrinsic safety type portable detection robot body driving device adopts low power consumption top speed reaction guard grating technology, adopts advanced motor load matching technology, and uses a high capacity lithium manganate battery set, and accordingly a low power consumption mine intrinsic safety type portable detection robot body driving device which needs no heavy explosive-proof box, and not only meets requirements for detection robot intrinsic safety explosion protection under protection environment, but also can meet requirements for portability of driving electric power and equipment loaded on a detection robot is provided.

Description

technical field [0001] The invention relates to a drive device, in particular to a mine intrinsically safe type portable detection robot body drive device. Background technique [0002] At present, the main body of mining rescue or detection robots at home and abroad is large, and the adaptive power supply of its walking drive motor mostly adopts 220V AC (drag line) or 24V and 48V DC Ni-MH power supply, and its intrinsically safe drive current is easily limited, so it is generally used Explosion-proof / explosion-proof and intrinsically safe devices or use inert gas filling to achieve the purpose of explosion-proof, the explosion-proof box is bulky and heavy. On the one hand, since the explosion-proof power supply device is usually a non-intrinsically safe design, its safety protection level is not high. If it is used for the detection of Class I environment in a disaster area, once the explosion-proof surface is damaged or the inert gas is volatilized and lost, it is easy to ...

[0002] At present, the main body of mining rescue or detection robots at home and abroad is large, and the adaptive power supply of its walking drive motor mostly adopts 220V AC (drag line) or 24V and 48V DC Ni-MH power supply, and its intrinsically safe drive current is easily limited, so it is generally used Explosion-proof / explosion-proof and intrinsically safe device or using inert gas filling to achieve the purpose of explosion-proof, the explosion-proof box is large and heavy

On the one hand, since the explosion-proof power supply device is usually a non-intrinsically safe design, its safety protection level is not high. If it is used for the detection of Class I environment in a disaster area, once the explosion-proof surface is damaged or the inert gas is volatilized and lost, it is easy to lose the explosion, resulting in secondary accidents. Accidents and disasters occur. On the other hand, the power safety barrier consumes a lot of power and the power supply efficiency is not high, which limits its application range for adaptive detection robots.
