Description

Technical Field

[0001] The present invention relates to the technical field of coal mine transportation, and specifically to an intelligent temperature-sensing control type coal mine coal transportation cooling device. Background Art

[0002] A coal mine is an area where humans mine coal resources in coal-rich mining areas. Generally, it is divided into underground coal mines and surface coal mines. When the coal seam is far from the surface, generally, underground roadways are dug to mine coal, which is an underground coal mine. When the distance between the coal seam and the surface is very close, generally, the surface soil layer is directly stripped to mine coal, which is a surface coal mine. Most coal mines are underground coal mines. After the underground coal mine is mined, coal mine transportation operations are required. However, during the transportation of coal mines, coal is a flammable substance. During transportation, friction with air or accumulation is likely to generate high temperatures. If the temperature is too high, it is easy to ignite the coal mine, thus bringing potential safety hazards and economic losses. In order to achieve the purpose of cooling coal mines during transportation, an intelligent temperature-sensing control type coal mine coal transportation cooling device is provided.

When it is found that the temperature in the transport vehicle is relatively high, the motor runs to drive the water outlet pipe to displace, and the displacement of the water outlet pipe drives the atomizing nozzle to move through the upper part of the transport vehicle; at the same time, the water pump runs, and the water inlet pipe transports the water in the water tank into the connecting pipe, and the water in the connecting pipe enters the water outlet pipe and is sprayed out through the atomizing nozzle. The sprayed water enters the transport vehicle, and the water cools the coal mine, which is convenient for cooling the coal mine during transportation and prevents the coal mine from spontaneous combustion and causing losses. 2. By setting up a winding mechanism, when the water outlet pipe is displaced and reset, the motor runs to drive the threaded rod to rotate, and the rotation of the threaded rod drives the winding drum to rotate. The rotation of the winding drum automatically winds the connecting pipe, so as to prevent the connecting pipe from being scattered or wound when the water outlet pipe is displaced and reset, thus affecting subsequent operations. At the same time, when the winding drum rotates, the rotating rod can rotate relative to the water inlet pipe, and the water in the water inlet pipe can flow into the connecting pipe through the communication groove, which is convenient for automatically winding and releasing the connecting pipe when the water outlet pipe is displaced to cool the inside of the transport vehicle.

A water pump 309 is installed on the outer wall of the water inlet pipe 308. A motor 310 is installed on the outer wall of the mounting seat 302. The output end of the motor 310 is connected to a threaded rod 311. The cooling mechanism 3 further includes a movable groove 312. The movable groove 312 is opened on the outer wall of the mounting seat 302. Movable blocks 313 are symmetrically and slidably connected to the inner wall of the movable groove 312.

[0019] In this embodiment: The coal mine is placed into the transport vehicle 1, and the transport vehicle 1 is used to transport the coal mine; the infrared temperature sensor 304 monitors the coal mine in the transport vehicle 1 in real time. When it is found that the temperature in the transport vehicle 1 is higher than the preset safety value, the motor 310 is started. The rotation of the motor 310 drives the threaded rod 311 to rotate. The rotation of the threaded rod 311 drives the movable block 313 to slide in the movable groove 312. The two movable blocks 313 displace in opposite directions in the movable groove 312. The displacement of the movable block 313 drives the slider 315 to displace in the opposite direction in the chute 317 through the X-shaped telescopic hinge 314. The slider 315 slides along the outer wall of the limiting rod 318, thereby driving the displacement frame 316 to displace. The displacement of the displacement frame 316 drives the water outlet pipe 319 to displace. The displacement of the water outlet pipe 319 drives the atomizing nozzle 320 to move through the upper part of the transport vehicle 1; at the same time, the water pump 309 operates, and the water inlet pipe 308 transports the water in the water tank 306 into the connecting pipe 321. The water in the connecting pipe 321 enters the water outlet pipe 319 and is sprayed out through the atomizing nozzle 320. The sprayed water enters the transport vehicle 1, and the water cools the coal mine; this design facilitates the cooling of the coal mine during transportation and prevents losses caused by the spontaneous combustion of the coal mine.

A winding drum 403 is fixedly connected between the two support plates 401 on the outer wall of the rotating rod 402. One end of the connecting pipe 321 is fixedly connected to the winding drum 403. A communication groove 404 is formed inside the rotating rod 402 and the winding drum 403. The connecting pipe 321 and the water inlet pipe 308 are connected through the communication groove 404. One end of the rotating rod 402 is fixedly connected to a first bevel gear 405.

The rotation of the third bevel gear 408 drives the mounting shaft 407 to rotate. The rotation of the mounting shaft 407 drives the second bevel gear 406 to rotate. The rotation of the second bevel gear 406 drives the first bevel gear 405 to rotate. The rotation of the first bevel gear 405 drives the rotating rod 402 to rotate. The rotation of the rotating rod 402 drives the winding drum 403 to rotate. The rotation of the winding drum 403 drives the connecting pipe 321 to move and be released from the winding drum 403.
