Description

Technical Field

[0001] This application relates to the technical field of underground environmental engineering, and more particularly, to an underground engineering ventilation and cooling system. Background Art

[0002] In the related art, during the use of the underground engineering ventilation and cooling system, most of the filter nets of the ventilation and cooling equipment will adhere to a certain amount of dust and particulate matter. This is because the suspended particles and pollutants in the air are intercepted by the filter net and accumulate on the filter net. These dust and particulate matter deposited on the filter net will gradually accumulate, resulting in a decrease in the filtration efficiency and may have an adverse impact on the operation of the equipment. At the same time, by adjusting the appropriate air humidity, the suspension time of dust and particulate matter in the air can also be reduced, which helps to improve the air quality and lower the temperature in the air. However, in this method, when the staff replaces the filter net, they need to manually remove the old filter net from the equipment, and at the same time, they need to disassemble the bolts with a wrench or a screwdriver. When installing a clean filter net, the staff also needs to ensure that the filter net is correctly aligned and safely fixed in its position. Therefore, it is too dependent on manual operation by the staff. At the same time, when the filter net is installed, there may still be a phenomenon of misalignment of the filter net installation, which brings potential safety hazards to the normal operation of the equipment. At the same time, during the process of manually replacing the filter net by the staff, an independent driving structure is still required to control the opening or closing of the humidifying structure, which increases the operation steps of the staff and further brings inconvenience to the actual use of the staff.

Second, the existing second servo motor is used to realize dust cleaning during the process of replacing the installation frame and the filter net, so that the soaked filter net is cleaner. Third, the existing second servo motor is used to control the penetration of the humidifying holes, so that the opening and closing of the humidifying holes can be freely adjusted according to the humidity of the environment during use. Finally, the above three effects are all controlled by the inlet of a single second servo motor, without introducing too much drive, effectively optimizing the circuit structure.

[0041] The following describes the underground engineering ventilation and cooling system according to an embodiment of the present application with reference to the drawings.

[0042] As Figures 1-11 shown, the underground engineering ventilation and cooling system according to an embodiment of the present application includes: a ventilation support mechanism 1, a water circulation cleaning mechanism 2, and a filter screen cleaning and cooling mechanism 3.

[0043] As Figure 1 andFigure 2 As shown, there is a ventilation support mechanism 1, a water circulation cleaning mechanism 2. The water circulation cleaning mechanism 2 is arranged at the lower end of the ventilation support mechanism 1. The water circulation cleaning mechanism 2 filters the sewage and cools it down again. There is a filter screen cleaning and cooling mechanism 3. The filter screen cleaning and cooling mechanism 3 is located at the front end of the ventilation support mechanism 1 and the water circulation cleaning mechanism 2. The water after being filtered and cooled by the water circulation cleaning mechanism 2 flows into the interior of the filter screen cleaning and cooling mechanism 3. The water after being cooled by the water circulation cleaning mechanism 2 cleans and cools the filter screen cleaning and cooling mechanism 3.

[0044] During use, the filter screen cleaning and cooling mechanism 3 can replace the filter screen and make it enter the interior of the water circulation cleaning mechanism 2 for soaking. At the same time, the filter screen cleaning and cooling mechanism 3 can automatically replace and clean the filter screen, and realize the humidification function by lifting the height of the filter screen, thus meeting the use in a variety of working environments. The water circulation cleaning mechanism 2 can also extract, filter and cool the water after soaking, and then make the cooled water flow into the interior of the filter screen cleaning and cooling mechanism 3. Then, through the ventilation support mechanism 1, the low temperature and moisture generated by the filter screen cleaning and cooling mechanism 3 are blown into the environment, thus effectively ensuring the stability of the ventilation and cooling effects in the working environment.

[0045] Such as Figure 3 、 Figure 4 and Figure 5As shown, the water circulation cleaning mechanism 2 includes a cleaning tank 201, a water passing frame 203 and a filter box 205. The cleaning tank 201 is fixedly connected to the inner wall of the lower end of the ventilation box 101. The water passing frame 203 is fixedly connected to the middle of the inner wall of the cleaning tank 201. The filter box 205 is fixedly connected to the lower end of the water passing frame 203. The lower surface of the filter box 205 is fixedly connected to the inner bottom surface of the cleaning tank 201. A sealing short board 206 is connected to the upper end of the filter box 205 by bolts. The middle of the lower end of the sealing short board 206 is fixedly connected with a water filtering wire frame 207. A sealing wide board 204 is connected to the rear end of the water passing frame 203 by bolts. A protective door 202 is hingedly connected to the rear end of the cleaning tank 201. A condenser 208 is fixedly connected to the middle of the rear end of the inner bottom surface of the cleaning tank 201. A first high-pressure water pump 209 is fixedly connected to one side of the rear end of the inner bottom surface of the cleaning tank 201. The water suction port of the first high-pressure water pump 209 is fixedly connected with a first multi-way pipe 210. The first multi-way pipe 210 is connected to the filter box 205 in a penetrating manner. A second high-pressure water pump 211 is fixedly connected to the other side of the rear end of the inner bottom surface of the cleaning tank 201. The water outlet of the second high-pressure water pump 211 is fixedly connected with a second multi-way pipe 212. The water outlet of the first high-pressure water pump 209 and the water inlet of the condenser 208 are connected by a hose. The water suction port of the second high-pressure water pump 211 and the water outlet of the condenser 208 are connected by a short pipe. Specifically, starting the first high-pressure water pump 209 can enable the first multi-way pipe 210 to suck water from the inside of the cleaning tank 201 through the filter box 205, and then drain it into the inside of the condenser 208 through the connecting short pipe. At this time, during the process of pumping the water inside the cleaning tank 201, the flowing cooling water inside the cleaning tank 201 realizes the slow flushing of the filter net 332, so that the water flow drives the dust and particulate impurities attached to the surface of the filter net 332 to flow towards the inside of the filter box 205 and be filtered by the water filtering wire frame 207, thereby ensuring the cleanliness during the circulation use of the cooling water.

[0046] As Figure 6 and Figure 7As shown, the filter screen cleaning and cooling mechanism 3 includes a second servo motor 301, a plurality of main gears 303, a cleaning brush 304, a mounting frame 306, a toothed plate 309, a water passing box 311, a water passing frame 313, a water passing cover 317, and a water flow conversion cover 325. The output end of the second servo motor 301 is fixedly connected with a rotating rod 302. Two main gears 303 are respectively fixedly connected to the outer walls on both sides of the rotating rod 302. The cleaning brush 304 is fixedly connected to the middle of the outer wall of the rotating rod 302. The mounting frame 306 is arranged inside the front ends of the ventilation box 101 and the cleaning box 201. Transmission grooves 308 are opened on both sides of the mutually approaching ends of the mounting frame 306. The toothed plates 309 are fixedly connected to the interiors of the transmission grooves 308. The main gears 303 are respectively meshed with the toothed plates 309. Among them, when the filter screen 332 needs to be cleaned, by starting the second servo motor 301, the rotating rod 302 can drive the main gears 303 to rotate. At this time, under the mutual meshing of the main gears 303 and the toothed plates 309, the filter screen 332 with attached dust and particulate impurities can move towards the inside of the cleaning box 201. At the same time, the filter screen 332 after being soaked inside the cleaning box 201 will move towards the upper part of the ventilation box 101 synchronously. At the same time, during the rising and falling process of the filter screen 332, the cleaning brush 304 will rotate following the rotating rod 302. At this time, the cleaning brush 304 sweeps the filter screen 332 during the replacement process, thereby effectively increasing the content of attached dust and particulate impurities on the surface of the filter screen 332 after soaking, greatly improving the ventilation effect of the device, and at the same time, it can also improve the filtration efficiency and extend the service life of the equipment. At the same time, the water level inside the cleaning box 201 can soak half of the cleaning brush 304. Therefore, the cleaning brush 304 is continuously cleaned by the cooling water during rotation, ensuring the cleanliness of the cleaning brush 304 during long-term use.

[0047] As Figure 8 , Figure 9 , Figure 10 and Figure 11As shown, a first water flow cavity 310 is provided at the front end of the upper part of the ventilation box 101.

Limiting grooves 315 are provided in the middle of the lower ends of the first water flow conversion cavities 314. Springs 316 are fixedly connected to the middle of the lower surfaces of the water flow frames 313. The upper surfaces of the water flow covers 317 are fixedly connected to the lower ends of the springs 316. The water flow covers 317 are located inside the first water flow conversion cavities 314 and are slidably connected inside the limiting grooves 315. Water flow conversion grooves 321 are provided at the upper ends of the mounting frames 306. A water flow cooling pipe 322 is fixedly connected to the middle of the mounting frames 306. A water flow conversion cover 325 is fixedly connected to the inner wall of one end of the water flow conversion groove 321. Third water flow conversion holes 326 are provided at one end of the upper part of the water flow conversion groove 321. Second water flow conversion cavities 328 are provided at the upper ends of the mounting frames 306. Fourth water flow conversion holes 327 are provided at one end of the upper part of the second water flow conversion cavities 328. The third water flow conversion holes 326 and the fourth water flow conversion holes 327 are both located inside the water flow conversion cover 325. Annular pipes 329 are provided at the mutually approaching ends of the water flow cooling pipes 322. A plurality of atomizing spray nozzles 330 are provided on the pipe bodies of the annular pipes 329. A plurality of connecting hoses 331 are fixedly connected to the upper parts of the annular pipes 329. The upper ends of the connecting hoses 331 are communicated with the second water flow conversion cavities 328. Two sliding plates 305 are respectively fixedly connected to the inner walls on both sides of the front ends of the ventilation box 101 and the cleaning box 201. Sliding grooves 307 are provided in the middle of the outer walls on both sides of the mounting frames 306. The mounting frames 306 are slidably connected to the outer walls of the sliding plates 305 through the sliding grooves 307. Limiting frames 318 are respectively fixedly connected to the upper ends of the first water flow conversion cavities 314. The upper ends of the water flow covers 317 are respectively clamped with the limiting frames 318. The upper ends of the mounting frames 306 respectively penetrate through the limiting grooves 315 and are clamped with the lower ends of the water flow covers 317. First water flow conversion holes 319 are provided at both the front end and the rear end of the upper part of the water flow covers 317. Second water flow conversion holes 320 are provided on the mutually approaching sides of the lower parts of the water flow covers 317. Drainage cavities 323 are provided at the lower ends of the mounting frames 306. A plurality of drainage holes 324 are provided at the lower parts of the mutually approaching ends of the drainage cavities 323. The upper ends of the water flow cooling pipes 322 are communicated with the water flow conversion grooves 321. The lower ends of the water flow cooling pipes 322 are communicated with the drainage cavities 323. Specifically, when the staff needs to replace the filter screen 332, the second servo motor 301 is started to make the main gear 303 mesh with the toothed plate 309, so that the filter screen 332 with dust and particulate matter attached to its surface moves towards the inside of the cleaning box 201. At the same time, the filter screen 332 after being soaked inside the cleaning box 201 will synchronously move towards the upper part of the ventilation box 101.At this time, during the downward movement of the filter screen 332 with dust and impurity particles, the water passing cover 317 will move downward inside the limit groove 315 under the action of the spring 316. At this time, the first water flow conversion hole 319 will be located inside the limit groove 315, and the water inside the second water passing cavity 312 cannot flow into the outside of the first water flow conversion cavity 314 through the first water flow conversion hole 319, thus achieving the purpose of automatic cut-off. At the same time, when the filter screen 332 moves upward after soaking and cleaning, the water passing cover 317 will move toward the inside of the limit frame 318 under the action of the installation frame 306 and be clamped with the limit frame 318. At this time, the water inside the second water passing cavity 312 will enter the inside of the water flow conversion groove 321 through the first water flow conversion cavity 314 and the first water flow conversion hole 319, thus achieving the purpose of automatic flow opening. At this time, it will then flow into the inside of the drainage cavity 323 through the water passing cooling pipe 322. During the flowing process, the cooling water can discharge the lower temperature to the inside of the ventilation box 101 through the water passing cooling pipe 322. At this time, under the action of the first servo motor 103 and the ventilation fan blade 104, the cooled cold air is discharged to the environment. When it is necessary to humidify the environment, it can be achieved by controlling the number of rotation turns of the second servo motor 301. Among them, when it is necessary to humidify the environment, by starting the second servo motor 301, the position of the installation frame 306 inside the limit groove 315 can be controlled. When the upper part of the installation frame 306 is completely clamped with the limit frame 318, while the cooling water enters the inside of the water flow conversion groove 321 through the first water flow conversion hole 319, it will also enter the inside of the water flow conversion cover 325 through the second water flow conversion hole 320 and the third water flow conversion hole 326. At this time, the cooling water inside the water flow conversion cover 325 will enter the inside of the second water flow conversion cavity 328 through the fourth water flow conversion hole 327, then be discharged into the inside of the annular pipe 329 through the connecting hose 331, and then be sprayed outward through a plurality of atomizing nozzles 330. At this time, the wind blown by the first servo motor 103 and the ventilation fan blade 104 will carry the sprayed moisture and flow toward the external environment, thus achieving the purpose of cooling, humidifying, and ventilating the external environment. Among them, for this device, by starting the second servo motor 301, first, the second servo motor 301 can control the rising and falling of the two installation frames 306 to complete the replacement of the corresponding filter screens 332, thus ensuring the efficiency of filtering dust and particulate impurities of the device and improving the ventilation effect at the same time. Second, during the process of replacing the installation frame 306 and the filter screen 332 by using the existing second servo motor 301, dust cleaning is realized. Third, by using the existing second servo motor 301, the penetration of the humidifying holes is controlled, so that the opening and closing of the humidifying holes can be freely adjusted according to the humidity of the environment during use. Finally, the above three effects are all controlled through the wire inlet of a single second servo motor 301, without introducing too much drive, effectively optimizing the circuit structure.

[0048] Specifically, the working principle of the underground engineering ventilation and cooling system is as follows: During the process of workers using the device to ventilate the underground construction environment, during the long-term use of the filter net 332, a certain amount of dust and particulate impurities will adhere to its surface. At this time, by starting the second servo motor 301, the rotating rod 302 can drive the main gear 303 to rotate. At this time, under the mutual meshing of the main gear 303 and the toothed plate 309, the filter net 332 with adhered dust and particulate impurities can move towards the inside of the cleaning box 201. At the same time, after being soaked inside the cleaning box 201, the filter net 332 will move synchronously towards the upper part of the ventilation box 101. At the same time, during the ascending and descending process of the filter net 332, the cleaning brush 304 will rotate following the rotating rod 302. At this time, the cleaning brush 304 sweeps the filter net 332 during the replacement process, thereby effectively increasing the content of adhered dust and particulate impurities on the surface of the filter net 332 after soaking, greatly improving the ventilation effect of the device, and at the same time, it can also improve the filtration efficiency and extend the service life of the equipment. At the same time, the water level inside the cleaning box 201 can soak half of the cleaning brush 304. Therefore, the cleaning brush 304 is continuously washed by the cooling water during rotation, ensuring the cleanliness of the cleaning brush 304 during long-term use. At this time, during the downward movement of the filter net 332 with dust and impurity particles, the water passing cover 317 will move downward inside the limit groove 315 under the action of the spring 316. At this time, the first water flow conversion hole 319 will be located inside the limit groove 315, and the water inside the second water flow cavity 312 cannot flow through the first water flow conversion hole 319 to the outside of the first water flow conversion cavity 314, thus achieving the purpose of automatic interception. At the same time, when the filter net 332 after soaking and cleaning moves upward, the water passing cover 317 will move towards the inside of the limit frame 318 under the action of the mounting frame 306 and be clamped with the limit frame 318. At this time, the water inside the second water flow cavity 312 will enter the inside of the water flow conversion groove 321 through the first water flow conversion cavity 314 and the first water flow conversion hole 319, thus achieving the purpose of automatic flow opening. At this time, it will then flow towards the inside of the drainage cavity 323 through the water passing cooling pipe 322. During the flowing process, the cooling water can discharge the lower temperature to the inside of the ventilation box 101 through the water passing cooling pipe 322. At this time, under the action of the first servo motor 103 and the ventilation fan blade 104, the cooled cold air is discharged to the environment. When it is necessary to humidify the environment, it can be achieved by controlling the number of rotation turns of the second servo motor 301. Among them, when it is necessary to humidify the environment, by starting the second servo motor 301, the position of the mounting frame 306 inside the limit groove 315 can be controlled. When the upper part of the mounting frame 306 is completely clamped with the limit frame 318, while the cooling water enters the inside of the water flow conversion groove 321 through the first water flow conversion hole 319, it will also enter the inside of the water flow conversion cover 325 through the second water flow conversion hole 320 and the third water flow conversion hole 326.At this time, the cooling water inside the water flow conversion cover 325 will enter the inside of the second water flow conversion cavity 328 through the fourth water flow conversion hole 327, then be discharged into the inside of the annular pipe 329 through the connecting hose 331, and then be sprayed outwards through a plurality of atomizing nozzles 330. At this time, the wind blown by the first servo motor 103 and the ventilation fan blades 104 will carry the sprayed moisture and flow towards the external environment, thereby achieving the purpose of cooling, humidifying and ventilating the external environment.
