Description

Technical Field

[0001] The invention belongs to the technical field of cold air cooling, and in particular to a cold air cooling system for high geothermal tunnel construction. Background Art

[0002] The construction of high geothermal tunnels is due to the extremely high temperature inside the tunnels in the high geothermal environment, which poses a threat to the health of construction workers and may cause health problems such as heat stroke and heat stroke. It will also affect the performance and stability of construction equipment and may even cause equipment failure. Therefore, it is necessary to use a cold air cooling system during construction.

[0003] The cold air cooling system is an efficient cooling device that integrates multiple components such as fans, wet curtains (or evaporative media), water tanks and water pumps, and control systems. It uses the principle of evaporative cooling to reduce the ambient temperature through air flow and water evaporation, providing people with a more comfortable working and living environment.

[0004] However, it will also lead to higher humidity inside the tunnel. High humidity environment may cause the growth of bacteria, mold and other microorganisms in the air. Construction workers may suffer from respiratory infections, allergies and other problems if they inhale these microorganisms for a long time. At the same time, excessive humidity may also lead to a relative decrease in the oxygen content in the air, increasing the burden on the respiratory system of construction workers. At the same time, humid air will cause the conductive metal, magnetic silicon steel sheet and metal casing in the power equipment to rust, reducing the performance and service life of the equipment.

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0023] like Figures 1 to 8 As shown, a cold air cooling system for high geothermal tunnel construction according to an embodiment of the present invention comprises an air inlet pipe 1, an air exhaust pipe 2 and a cooling component; Both the air inlet pipe 1 and the exhaust pipe 2 are connected to fans. When the fan in the air inlet pipe 1 is started, external air can be blown into the tunnel. When the fan in the exhaust pipe 2 is started, the gas in the tunnel can be transported outward, thereby realizing air circulation in the tunnel. At the same time, the heat in the tunnel can also be exchanged with the cold air outside to achieve a cooling effect.

[0024] The cooling assembly includes a water tank 3, a water pump 4, a water outlet pipe 5 and a water suction pipe 6. The water tank 3 is arranged between the air inlet pipe 1 and the air outlet pipe 2. The water pump 4 is fixedly installed at the top of the water tank 3. The suction end of the water pump 4 is connected with the water tank 3 through the water suction pipe 6. The output end of the water pump 4 extends to the inside of the air inlet pipe 1 through the water outlet pipe 5 and is provided with an atomizing nozzle. By starting the water pump 4, the water in the water tank 3 can be extracted through the water suction pipe 6, sprayed out through the water outlet pipe 5, and finally sprayed on the inside of the air inlet pipe 1 through the atomizing nozzle. At this time, the gas flow in the air inlet pipe 1 can drive the atomized water into the tunnel. The atomized water droplets can absorb the hot air in the tunnel, and the dust generated by the construction in the tunnel can also be reduced. It can not only cool the environment in the tunnel, but also further improve the air quality in the tunnel.

[0025] A filter cotton 12 is arranged inside the exhaust pipe 2, and a cleaning plate 11 is rotatably mounted on the filter cotton 12, and one end of the cleaning plate 11 is in contact with the filter cotton 12; When the exhaust pipe 2 discharges the gas in the tunnel, the water mist in the tunnel is also sucked out. At this time, the filter cotton 12 can not only block and filter the dust in the air, but also absorb the water mist floating in the air. The cleaning plate 11 maintains the squeezing effect on the filter cotton 12. When the cleaning plate 11 rotates, it not only rotates and squeezes the filter cotton 12 to squeeze out the water in the filter cotton 12, but also scrapes off the dust on the filter cotton 12.

[0026] A rotating rod 10 is rotatably mounted on the filter cotton 12, a first impeller 9 is fixedly mounted on the rotating rod 10, and a cleaning plate 11 is fixedly mounted on the outer wall of the rotating rod 10; When the exhaust pipe 2 extracts the gas in the tunnel, the airflow will impact the blades of the first impeller 9, so that the first impeller 9 drives the rotating rod 10 to rotate, thereby controlling the cleaning plate 11 to rotate on the outer wall of the filter cotton 12.

[0027] A liquid storage box 7 is provided at the bottom of the exhaust pipe 2 , a filter cloth 18 is provided inside the liquid storage box 7 , and the liquid storage box 7 is connected to the water tank 3 through a water supply pipe 8 .

[0028] The top of the liquid storage box 7 is opened, and the liquid storage box 7 is connected to the inner cavity of the exhaust pipe 2. When the cleaning plate 11 rotates against the outer wall of the filter cotton 12, the squeezed water and dust will directly fall into the interior of the liquid storage box 7, and the fallen impurities will be filtered by the filter cloth 18 arranged inside the liquid storage box 7 to complete the solid-liquid separation. The water dripping through the filter cloth 18 can enter the interior of the water tank 3 through the water supply pipe 8 (under the action of the water pump 4, the interior of the water tank 3 will be under negative pressure, so the water in the liquid storage box 7 can be absorbed through the water supply pipe 8).

[0029] As a preferred embodiment of the present invention, four brackets 17 are fixedly installed on the inner wall of the liquid storage box 7, and one end of the four brackets 17 away from the inner wall of the liquid storage box 7 is connected through a connecting platform 24, and a rotating shaft 23 is rotatably installed inside the connecting platform 24. A first pull rope 19 is provided inside the four brackets 17, and one end of the four first pull ropes 19 is fixedly connected to the outer wall of the rotating shaft 23, and the other ends of the four first pull ropes 19 are respectively connected to the bottom of the four corners of the filter cloth 18.

[0030] The connecting platform 24 is fixed at the center position of the liquid storage box 7 by four brackets 17. When the control shaft 23 is rotated inside the connecting platform 24, the shaft 23 will simultaneously reel in the four first pull ropes 19. At this time, the four corners of the filter cloth 18 will move upward under the contraction of the four first pull ropes 19. At this time, the filter cloth 18 will have four corners on top, and the dust filtered by the filter cloth 18 will accumulate in the center.

[0031] As a preferred embodiment of the present invention, the liquid storage box 7 is fixedly installed with a driving motor 14, the output shaft of the driving motor 14 is fixedly installed with a driving wheel 15, the top of the rotating shaft 23 is fixedly installed with a driven wheel 16, and the driving wheel 15 and the driven wheel 16 are connected by a belt.

[0032] By starting the driving motor 14, the driving wheel 15 can be driven to rotate, and under the action of the belt, the driven wheel 16 can be driven to rotate. When the driven wheel 16 rotates, it will drive the rotating shaft 23 to rotate and simultaneously reel in or unreel the four first pull ropes 19. When reeling in, the four corners of the filter cloth 18 can be lifted, and when reeling in, the four corners of the filter cloth 18 can be put down. Positioning blocks can be set on the bottom surface of the four corners of the filter cloth 18, which can be made of magnetic material. When the filter cloth 18 is horizontal, the magnetic positioning blocks set at the bottom can attract the magnetic blocks on the inner wall of the liquid storage box 7, so as to position the filter cloth 18 and keep the filter cloth 18 in a horizontal state.

[0033] As a preferred embodiment of the present invention, a fixed block 25 and a sliding block 26 are fixedly installed inside the four brackets 17, a return spring is arranged between the fixed block 25 and the sliding block 26, the first pull rope 19 passes through the fixed block 25 and is slidably connected to the fixed block 25, and the first pull rope 19 is fixedly connected to the sliding block 26.

[0034] When the rotating shaft 23 reels the four first pull ropes 19, the first pull ropes 19 will drive the sliding block 26 to slide inside the bracket 17 toward the fixed block 25. At the same time, the reset spring will also deform and store elastic potential energy until the rotating shaft 23 is unwound. The reset spring releases the elastic potential energy and separates the sliding block 26 from the fixed block 25, so that the first pull ropes 19 are reset and the filter cloth 18 returns to a horizontal position.

[0035] As a preferred embodiment of the present invention, a positioning cylinder 29 is fixedly installed at the inner bottom end of the liquid storage box 7, a carrying plate 27 is slidably installed inside the positioning cylinder 29, a plurality of extrusion plates 13 are slidably installed on the carrying plate 27, the bottom end of the extrusion plate 13 extends to the inside of the carrying plate 27, and a transmission assembly is provided at the bottom end of the extrusion plate 13 for controlling the sliding of the extrusion plate 13.

[0036] When the rotating shaft 23 reels the four first pull ropes 19, the supporting plate 27 can be controlled to slide on the positioning cylinder 29 until the bottom end of the filter cloth 18 fits with the top end of the supporting plate 27. A sliding groove for the extrusion plate 13 to slide is provided on the supporting plate 27. By controlling the transmission component to control multiple extrusion plates 13 to slide toward the center of the supporting plate 27 at the same time, the filter cloth 18 can be squeezed from the outside of the filter cloth 18, so that the moisture in the filter cloth 18 can be squeezed out quickly.

[0037] As a preferred embodiment of the present invention, the transmission assembly includes a transmission rod 33, a first spiral groove 39, a first guide block 38 and a first coil spring 40. The transmission rod 33 is rotatably installed inside the carrier plate 27, one end of the transmission rod 33 passes through the extrusion plate 13, the first spiral groove 39 is opened on the outer wall of the transmission rod 33, the first guide block 38 is fixedly installed inside the extrusion plate 13, one end of the first guide block 38 extends to the inside of the first spiral groove 39, and the first coil spring 40 is arranged on the outer wall of the transmission rod 33.

[0038] When the extrusion plate 13 moves toward the center of the supporting disk 27, the first guide block 38 will slide along the inside of the first spiral groove 39, thereby driving the transmission rod 33 to rotate, and at the same time driving the first coil spring 40 to rotate, so that the first coil spring 40 is deformed and stores elastic potential energy. When the first coil spring 40 releases the elastic potential energy, it can drive the transmission rod 33 to reset. With the cooperation of the first spiral groove 39 and the first guide block 38, the extrusion plate 13 close to the center of the supporting disk 27 can be controlled to slide in the direction away from the center of the supporting disk 27.

[0039] As a preferred embodiment of the present invention, a transmission gear 34 is fixedly installed at one end of the transmission rod 33 away from the first coil spring 40, and a transmission ring 36 is fixedly installed inside the supporting plate 27. A tooth block group 35 meshing with the transmission gear 34 is provided on the transmission ring 36. The number of tooth block groups 35 and the transmission gear 34 is consistent with the number of extrusion plates 13, and multiple tooth block groups 35 are intermittently arranged at the top of the transmission ring 36.

[0040] When the transmission ring 36 drives the tooth block group 35 to engage with the transmission gear 34, as the transmission ring 36 rotates, the extrusion plate 13 can be moved toward the center of the circle of the carrier disk 27 with the cooperation of the first spiral groove 39 and the first guide block 38. Since the tooth block group 35 is intermittently arranged, when the tooth block group 35 is not engaged with the transmission gear 34, the first coil spring 40 releases its elastic potential energy, driving the transmission rod 33 to reset and rotate, and cooperates with the first spiral groove 39 and the first guide block 38 to make the extrusion plate 13 slide in the direction away from the center of the circle of the carrier disk 27. As multiple tooth block groups 35 intermittently engage with the transmission gear 34, multiple extrusion plates 13 can be controlled to slide back and forth at the same time, thereby achieving reciprocating extrusion of the filter cloth 18, thereby further improving the water filtering effect.

[0041] As a preferred embodiment of the present invention, a transmission cylinder 45 is slidably installed inside the positioning cylinder 29, a connecting rod 47 is fixedly installed on the top of the transmission cylinder 45, and the top of the connecting rod 47 is fixedly connected to the bottom end of the carrier plate 27; A rotating ring 41 is rotatably mounted on the top of the positioning cylinder 29 , a second guide block 43 is fixedly mounted on the inner wall of the rotating ring 41 , a second spiral groove 44 is formed on the outer wall of the transmission cylinder 45 , the second guide block 43 extends to the inside of the second spiral groove 44 , and a second coil spring 32 is arranged on the outer wall of the rotating ring 41 .

[0042] By cooperating with the second spiral groove 44 and the second guide block 43, the rotating ring 41 can be driven to rotate when the transmission cylinder 45 slides inside the positioning cylinder 29. When the transmission cylinder 45 slides upward inside the positioning cylinder 29, the supporting plate 27 will be driven to slide upward under the action of the connecting rod 47 and approach the filter cloth 18. At this time, the rotating ring 41 will rotate, and at the same time, the second coil spring 32 will be driven to deform and store elastic potential energy. The elastic potential energy is released by the second coil spring 32, so as to drive the rotating ring 41 to reset and rotate. The second spiral groove 44 and the second guide block 43 cooperate to make the transmission cylinder 45 reset and slide downward inside the positioning cylinder 29.

[0043] As a preferred embodiment of the present invention, the internal thread of the transmission cylinder 45 is connected to a threaded rod 28, a connecting plate 37 is fixedly installed on the top of the threaded rod 28, the connecting plate 37 is fixedly connected to the transmission ring 36, a rotating rod 21 is slidably installed inside the threaded rod 28, and a second impeller 22 is fixedly installed on the bottom end of the rotating rod 21.

[0044] The rotation of the threaded rod 28 can drive the transmission cylinder 45 to slide. When the transmission cylinder 45 slides upward until it is disengaged from the thread between the threaded rod 28 and the transmission cylinder 45, the transmission cylinder 45 will not continue to slide. Under the continuous action of the threaded rod 28, the transmission cylinder 45 will shake up and down to a certain extent, which will not affect the coordination of subsequent structures. When the threaded rod 28 rotates, it will drive the transmission ring 36 to rotate through the connecting plate 37.

[0045] A limit rod is provided on the rotating rod 21 for limiting the sliding trajectory of the threaded rod 28 so that the threaded rod 28 can only slide along the outer wall of the rotating rod 21. At the same time, when the rotating rod 21 rotates, the threaded rod 28 will also be driven to rotate. When the accumulated water inside the liquid storage box 7 enters the water tank 3 through the water supply pipe 8, the water flow will impact the second impeller 22 to make it rotate, which will also drive the rotating rod 21 to rotate.

[0046] As a preferred embodiment of the present invention, a fixed disk 30 and a sliding disk 31 are fixedly installed on the outer wall of the positioning cylinder 29, the fixed disk 30 is arranged above the sliding disk 31, a top pressure spring is arranged between the fixed disk 30 and the sliding disk 31, and the top end of the sliding disk 31 is fixedly connected to the second pull rope 20, the second pull rope 20 passes through the fixed disk 30 and is fixedly connected to the first pull rope 19; A water inlet cavity 42 connected to the water supply pipe 8 is formed inside the bottom end of the positioning cylinder 29 , and a water inlet hole 46 is formed on the outer wall of the positioning cylinder 29 .

[0047] When the rotating shaft 23 rotates to reel in the four first pull ropes 19, the four first pull ropes 19 will pull the four corners of the filter cloth 18 at the same time. As the first pull ropes 19 shorten, the second pull ropes 20 will also be pulled upward and shortened until the sliding plate 31 is pulled to slide toward the fixed plate 30. At this time, the top pressure spring will also be deformed and store elastic potential energy until the sliding plate 31 releases the obstruction of the water inlet hole 46. At this time, the accumulated water in the liquid storage box 7 will enter the water inlet cavity 42 through the water inlet hole 46, and then pass through The water supply pipe 8 enters the water tank 3, and the second impeller 22 drives the rotating rod 21 to rotate, controls the threaded rod 28 to rotate, and causes the transmission cylinder 45 to drive the supporting plate 27 to slide upward until it fits with the filter cloth 18. At this time, the threaded rod 28 drives the transmission ring 36 to rotate through the connecting plate 37. With the cooperation of the intermittently arranged tooth block group 35 and the transmission gear 34, the first spiral groove 39 and the first guide block 38, the multiple extrusion plates 13 are controlled to slide back and forth at the same time, so as to realize the reciprocating extrusion of the filter cloth 18, thereby further improving the water filtering effect.

[0048] Working principle: when the exhaust pipe 2 discharges the gas in the tunnel, the water mist in the tunnel will also be sucked out. At this time, the filter cotton 12 set can not only block and filter the dust in the air, but also absorb the water mist floating in the air. The cleaning plate 11 maintains the squeezing effect on the filter cotton 12. When the cleaning plate 11 rotates, it will not only rotate and squeeze the filter cotton 12 to squeeze out the water in the filter cotton 12, but also scrape off the dust on the filter cotton 12. The squeezed water and dust will directly fall into the interior of the liquid storage box 7, and the filter cloth 18 set inside the liquid storage box 7 will filter the fallen impurities to complete the solid-liquid separation. The water dripping through the filter cloth 18 can enter the interior of the water tank 3 through the water supply pipe 8, which can not only cool down the tunnel, but also reduce the water content in the tunnel to ensure the construction environment.

[0049] The driving motor 14 drives the driving wheel 15 to rotate, and the driven wheel 16 can be driven to rotate under the action of the belt, so that the rotating shaft 23 can reel in the four first pull ropes 19 at the same time. At this time, the four first pull ropes 19 will pull the four corners of the filter cloth 18 at the same time. As the first pull ropes 19 shorten, the second pull ropes 20 will also be pulled upward and shortened until the sliding plate 31 is pulled to slide toward the position of the fixed plate 30. At this time, the top pressure spring will also be deformed and store elastic potential energy until the sliding plate 31 releases the obstruction to the water inlet 46. At this time, the accumulated water in the liquid storage box 7 will pass through the water inlet The hole 46 enters the interior of the water inlet chamber 42 and then enters the water tank 3 through the water supply pipe 8. At the same time, the second impeller 22 drives the rotating rod 21 to rotate, controls the threaded rod 28 to rotate, and causes the transmission cylinder 45 to drive the supporting plate 27 to slide upward until it fits with the filter cloth 18. At this time, the threaded rod 28 drives the transmission ring 36 to rotate through the connecting plate 37. With the cooperation of the intermittently arranged tooth block group 35 and the transmission gear 34, the first spiral groove 39 and the first guide block 38, the multiple extrusion plates 13 are controlled to slide back and forth at the same time, so as to realize the reciprocating extrusion of the filter cloth 18 and further improve the water filtering effect.
