A size-adjustable underground cooling device for coal mine development

Abstract

The invention discloses a size-adjustable downhole cooling device for coal mine development, which includes a water storage box, a driving gear, a manual telescopic rod and a water pump. The rear end bearing of the rod is connected to the front side of the water delivery box, the inner bearing of the water delivery box is connected with a second rotating rod, and the outer key of the second rotating rod is connected with a set of bevel teeth, and the set of bevel teeth The inner key of the screw rod is connected with the screw rod, and the outer thread of the screw rod is connected with the extension board, and the inside of the extension board is provided with a water delivery tank. This size-adjustable coal mine development adopts a downhole cooling device. The cooling device is located inside the mine. Control the rotation of the rotating rod to change the angle of the support mechanism, turn the support mechanism out of the cooling device, extend the cooling device, and limit the cooling device. The cooling device can be moved, and the rotating rod can be reversely rotated later to store the support mechanism, which is convenient for transferring the entire cooling device and is more convenient to use.

Description

technical field [0001] The invention relates to the technical field related to coal mines, in particular to a size-adjustable downhole cooling device for coal mine development. Background technique [0002] Coal is the most important solid fuel, and it is a kind of combustible organic rock. Coal is formed from luxuriant plants growing in a certain geological age. Formed by the natural coalification of long geological ages, coal needs to be mined and utilized, and a coal mine is a reasonable space for human beings to excavate when digging geological layers rich in coal. Coal mines include open-pit mining and underground mining, among which underground During mining operations, workers are required to work underground in coal mines, and the underground operating environment is sultry, dust flutters during the mining process, and the working environment is poor. It is necessary to use auxiliary cooling devices to improve the underground mining environment. [0003] However, th...
