Description
Technical Field
The utility model relates to a robot technical field in the pit, especially a wireless charging device for colliery is robot in pit.
Background
The total amount of coal resources in China is nearly 6 trillion tons, the resource amount buried below 1000m accounts for 53%, an energy structure mainly based on coal is a necessary choice for the current situation of energy resources in China, and the coal is stored for a long time, along with the gradual reduction of shallow coal resources, the development of coal is transferred to a deep part, and the coal mining system is in a dangerous mining environment with unclear geological conditions, unclear threats and multiple disasters, and the intelligent mining technology is an important means for ensuring the production safety of coal mines. The intelligent coal mining in China realizes the control of fully mechanized complete equipment laneways and the ground, forms an unmanned operation and manned inspection mining mode, but has difficulties in unmanned inspection and intelligent early warning of the underground main coal flow transportation working face of the coal mine. In order to realize the 'people reduction and unmanned' intelligent mining in the underground coal mine production process, the national emergency management department provides a research plan for developing 38 robots suitable for the underground safe production of the coal mine.
At present, around the research and development of various robots in coal mines, one more and more prominent problem is the cruising ability and the battery charging mode of the robots. According to the underground coal mine mining environment, various robots required by the national emergency administration and the coal safety mining center to operate underground must meet the explosion-proof requirement, and all underground electrical equipment must obtain corresponding coal mine safety certification. The weight of the existing various underground intelligent mining robots is increased abnormally obviously after the explosion-proof shell is added, and the robots are often made to be extremely heavy due to the self weight of the robots and the weight of a large-volume battery. The amount of the stored electric quantity of the existing lithium battery is closely related to the weight of the battery, and the self weight of the robot can be increased while the battery module is increased. Moreover, at present, the electric energy stored in the battery carried by the mining robot can only maintain the duration of the mining robot in the working surfaces of the middle and short roadways for one cycle or even less than one cycle, and the mining robot needs to return to the fixed charging pile for charging. Therefore, due to the limitation of the battery power, the robot cannot always complete the working duration of one cycle, and the working state and the application scene of the robot are seriously affected. For example, in some ultra-long working face roadways, the battery endurance of the robot is seriously insufficient, thereby influencing the mining and production of coal. Therefore, how to increase the battery endurance of the mining robot is a key research problem in the field of coal safety mining at present.
At present, various mobile robots adopted by mines have higher and higher requirements on the endurance of batteries carried by the mobile robots due to overlarge self weight, the existing mine robots adopt a charging mode for returning to a fixed charging position for wired charging for stopping the operation content being executed, the charging mode seriously restricts the moving distance and the endurance of the mine robots, and the working efficiency of the mine robots is greatly reduced. Therefore, a wireless charging system and a wireless charging device for the underground coal mine robot are needed, which can charge the robot in a multi-direction and long-time manner in an operation state under the condition of meeting the requirement of underground explosion-proof charging power.
