Description

Deep well pump pontoon for coal mine Technical Field The utility model relates to the technical field of water pumping equipment, in particular to a deep well pump pontoon for a coal mine. Background In underground mining operation of a coal mine, a large amount of underground water can continuously flow into an operation area, and if the underground water cannot be timely and effectively discharged, the safety production and the stable operation of equipment of the coal mine are seriously threatened. The mine ponding can cause that the tunnel is flooded, prevent personnel from passing through and running the equipment, and even cause serious safety accidents such as roof collapse, gas accumulation and the like. According to incomplete statistics, coal mine safety accidents caused by unsmooth drainage bring huge economic loss and casualties to industries each year. Therefore, the efficient and reliable drainage device is a key device essential for coal mine safety production. At present, underground coal mine drainage technology is continuously developed, and various drainage schemes are developed. The patent with the application number 202410669161.3 discloses a coal mine underground drainage device, and the device solves the problem of impurity filtration in the drainage process to a certain extent by arranging a filter bin and two symmetrically distributed filter mechanisms inside a drainage box. The filter design that it adopted, the cooperation of accessible telescopic link, first spring, spout and slider realizes convenient dismantlement and installation, conveniently carries out quick replacement when filter surface slime, cinder are too much. However, this solution still has certain limitations. In the complex operation environment in actual colliery in the pit, filtering mechanism in the drainage tank easily piles up because of a large amount of slime, cinder and blocks up, and only relies on the manual work to promote the filter and change, when the mine water inflow is big, the drainage task is urgent, operating efficiency is lower, is difficult to satisfy quick drainage's demand. Meanwhile, the device is relatively weak in design on the aspects of water level monitoring and automatic control in the drainage process, and the drainage strategy can not be timely and accurately adjusted according to the water level change, so that the water is possibly not timely drained or excessively drained, and energy waste is caused. In addition, conventional underground coal mine drainage methods have a number of problems. If the water pump is manually controlled to start or stop, a large amount of manpower is consumed, the reaction is slow, and rapid change of the water level cannot be timely dealt with. According to investigation, when the water is manually controlled, the water pump can not be started before the water level reaches the dangerous height under about 30% of conditions, and the water drainage timeliness is seriously affected. Although the partial drainage device is provided with a simple filtering device, the problems of low filtering precision, easy blockage, difficult cleaning and maintenance and the like generally exist, so that the drainage pump is frequently damaged due to the suction of impurities, and the equipment maintenance cost and the downtime are increased. The related data show that the equipment maintenance cost caused by the damage of impurities sucked by the drainage pump is millions each year, and the shutdown time is accumulated for more than thousands of hours, so that the production efficiency of the coal mine is seriously affected. Disclosure of utility model The utility model aims to provide a deep-well pump floating boat for a coal mine, which aims to solve the problems that the design of the device in the aspects of water level monitoring and automatic control in the drainage process is relatively weak, the drainage strategy can not be timely and accurately adjusted according to the water level change, and the drainage is possibly not timely or excessively performed, so that the energy waste is caused. In order to achieve the above purpose, the deep well pump floating pontoon for the coal mine comprises a pontoon body, wherein a water pumping component is arranged in the pontoon body and below the water level, the water pumping component pumps water out, the output end of the water pumping component is connected with a hose, the outer end of the hose is connected with an inclined tube, the outer end of the inclined tube is connected with a drainage pipeline on the shore, the water pumping component comprises a waste residue blocking bin, and one end of the waste residue blocking bin is connected with a water pump. The water pumping component is arranged below the water level in the hull based on the characteristic that the floating pontoon can rise and fall along with the water level, so that the water pumping component is always in an effective water absorption positio
