Description

Technical Field

[0001] The invention relates to the technical field of dust suppression devices, in particular to an urban high-altitude rotary spray dust suppression device. Background Art

[0002] Dust suppression refers to making water adhere to dust particles in the air, thereby making the dust in the air heavier and falling to the ground. In order to solve the problem of high-altitude dust in urban municipal roads, construction sites, factory areas and other places, fog piles are generally used to suppress dust particles floating in the city's air.

[0003] During the installation of traditional fog piles, the columns are usually fixed directly to the cement base by bolts. When the nozzles on the columns need to be replaced or repaired, the bolts need to be removed first to put down the columns, and then the rotating nozzles need to be repaired and replaced. The bolts need to be removed and installed repeatedly, resulting in cumbersome operation and low installation efficiency.

[0004] When installing the fog pile, the wires and high-pressure water pipes need to be connected to the main unit and the nozzle on the top of the column respectively. Usually, the wires and high-pressure water pipes are passed through the inside of the column together, so the two are easily entangled with each other, which is not convenient for maintenance and has safety hazards. In addition, due to the long length of the column, when the wires or high-pressure water pipes are damaged, they need to be completely pulled out, which is not convenient for operation;

[0005] The position of the mist pile is usually fixed after installation, and the dust suppression range of the nozzle is limited. When the dust suppression distance of the mist pile is required to be longer, the mist pile is difficult to play an effective dust suppression effect, and the position of the mist pile needs to be constantly adjusted. Therefore, the column needs to be repeatedly disassembled and installed, and the operation process is cumbersome and has poor flexibility. Summary of the invention

At this time, the wires and high-pressure water pipes inside the first column 401 can be exposed, which is convenient for the inspection of the wires or high-pressure water pipes. At the same time, the internal spaces of the first column 401 and the second column 402 are divided into two parts by the first partition plate 404, thereby realizing the separation of the wires and the high-pressure water pipes, avoiding entanglement between the two, and improving safety.

[0037] Specifically, Figure 1 , Figure 5-Figure 8 As shown, the mounting structure 6 includes a mounting cover 601 and a sliding sleeve 602 fixed on the mounting cover 601, the top end of the second column 402 is threadedly connected to the mounting cover 601, the upper and lower surfaces of the sliding sleeve 602 are respectively fixedly connected to the first mounting bar 603 and the second mounting bar 604, the first mounting bar 603 and the second mounting bar 604 are respectively provided with a first cavity 605 and a second cavity 606, the mounting cover 601 is provided with a wire hole 607, and the sliding sleeve 602 passes through the mounting cover 601; the sliding sleeve 602 completely passes through the mounting cover 601, thereby improving the stability of the rotating sprinkler 8, the interior of the two telescopic rods 703 is separated by the second partition plate 706, and the wires and high-pressure water pipes inside the second column 402 are passed into the internal space of the two telescopic rods 703 through the wire hole 607 provided in the mounting cover 601, and the flexibility is strong.

[0038] Specifically, Figure 1 , Figure 5-Figure 8As shown, the elongation structure 7 includes a second rotating shaft 701 and a second gear 702 fixed to the end of the second rotating shaft 701, the second rotating shaft 701 is rotatably connected inside the mounting cover 601, and two telescopic rods 703 are slidably connected inside the sliding sleeve 602, the lower surface of one telescopic rod 703 is fixedly connected to a second rack 704, and the upper surface of the other telescopic rod 703 is fixedly connected to a third rack 705, the second rack 704 and the third rack 705 are slidably connected to the inner walls of the second cavity 606 and the first cavity 605 respectively, and the second rack 704 and the third rack 705 are both meshed with the second gear 702, a motor 707 is fixedly connected to the outer wall of the mounting cover 601, and the second rotating shaft 701 is fixedly connected to the driving shaft of the motor 707, the interiors of the two telescopic rods 703 are fixedly connected to second partitions 706, and the ends of the two telescopic rods 703 are fixedly connected to a The rotary nozzles 8 are mounted on the second column 402 through the mounting cover 601. When the dust suppression range of the rotary nozzle 8 needs to be adjusted, the motor 707 drives the second shaft 701 to rotate, and the second shaft 701 drives the second gear 702 to rotate. Since the second gear 702 is simultaneously engaged with the second rack 704 and the third rack 705, and the first mounting bar 603 and the second mounting bar 604 are respectively provided with a first cavity 605 and a second cavity 606, the second gear 702 drives the second rack 704 and the third rack 705 to slide toward each other along the inner walls of the second cavity 606 and the first cavity 605, respectively. Then, the second rack 704 and the third rack 705 drive the two telescopic rods 703 to extend in opposite directions along the inner wall of the sliding sleeve 602, and the rotary nozzle 8 is mounted at the end of the telescopic rod 703. At this time, the dust suppression range of the rotary nozzle 8 can be increased, and the operation efficiency is high.

[0039] When the present invention is in use, the base plate 1 is fixed to the designated cement floor by bolts, and then the hexagonal wrench is inserted into the driving hole 311, and the worm 303 is rotated through the driving hole 311, and then the worm 303 drives the worm wheel 302 to rotate, and the worm wheel 302 drives the screw rod 301 to rotate, and then the screw rod 301 thread drives the slider 304 to slide upward along the guide rod 204, and at the same time, the limiting rod 308 provided on the support seat 201 is always engaged with the first limiting groove 309 on the slider 304 and the second limiting groove 310 on the first rotating shaft 305, so as to effectively The support plate 205 is prevented from rotating with the first rotating shaft 305 during the lifting process, thereby improving stability. At this time, the support plate 205 no longer blocks the wire storage groove 203 inside the support frame 202. The wires and the high-pressure water pipe are passed through the first column 401 and the second column 402, and then the first column 401 and the second column 402 are fixed as a whole through the flange 5. After the installation of the rotating nozzle 8 is completed, the worm 303 is continued to be rotated. When the worm 303 is continuously rotated, when the first gear 306 fixed at the end of the first rotating shaft 305 contacts the support seat 20 1 (the limiting rod 308 is separated from the first limiting groove 309 on the slider 304 and the second limiting groove 310 on the first rotating shaft 305, and the limiting is released), at this time, the first gear 306 is meshed with the first rack 307, and then when the screw rod 301 drives the slider 304 to continue to slide upward, the first gear 306 drives the first rotating shaft 305 to rotate 90 degrees clockwise, and the first rotating shaft 305 drives the support plate 205 and the first column 401 to rotate 90 degrees clockwise. At this time, the first column 401 is parallel to the ground, and the first column 401 is parallel to the ground. Align the groove at the bottom of a column 401 with the mounting seat 206 on the support plate 205 and fix it with bolts. Then, pass the excess wires and high-pressure water pipes at the bottom of the first column 401 through the center of the mounting seat 206 and put them into the wire storage slot 203. Pull out the ends of the wires and high-pressure water pipes from the holes reserved at the edge of the support frame 202 and connect them to the main unit of the fog pile. Then, use a hexagonal wrench to reversely rotate the worm 303 so that the slider 304 drives the support plate 205 to slide downward until the bottom surface of the support plate 205 is engaged with the edge of the support frame 202. At this point, the installation of the fog pile is completed. The installation process is simple and stable. At the same time, it effectively avoids the excess wires and high-pressure water pipes from being exposed to the outside, and it is highly safe.

When the worm 303 is continuously rotated, when the first gear 306 fixed at the end of the first rotating shaft 305 contacts the first rack 307 on the inner wall of the support seat 201, the first gear 306 is meshed with the first rack 307. Then, when the lead screw 301 drives the slider 304 to continue to slide upward, the first gear 306 drives the first rotating shaft 305 to rotate 90 degrees clockwise, and the first rotating shaft 305 drives the support plate 205 and the first column 401 to rotate 90 degrees clockwise. At this time, the first column 401 is parallel to the ground, and then the rotary sprinkler 8 can be repaired. After completing the repair of the rotary sprinkler 8, the worm 303 is rotated in the opposite direction until the bottom surface of the support plate 205 is re-engaged with the edge of the support frame 202, which improves the maintenance efficiency, is easy to operate, and has strong flexibility.

[0041] If the wires or high-pressure water pipes inside the first column 401 or the second column 402 are damaged, the first column 401 only needs to be laid down, and then the protective cover 403 on the first column 401 can be removed by removing the bolts. At this time, the wires and high-pressure water pipes inside the first column 401 can be exposed, which is convenient for the inspection of the wires or high-pressure water pipes. At the same time, the internal spaces of the first column 401 and the second column 402 are divided into two parts by the first partition plate 404, so as to separate the wires and the high-pressure water pipes, avoid the entanglement between the two, and improve safety;

[0042] The rotating nozzle 8 is installed on the second column 402 through the installation cover 601. When the dust suppression range of the rotating nozzle 8 needs to be adjusted, the motor 707 drives the second shaft 701 to rotate, and the second shaft 701 drives the second gear 702 to rotate. Since the second gear 702 is simultaneously engaged with the second rack 704 and the third rack 705, and the first mounting bar 603 and the second mounting bar 604 are respectively provided with a first cavity 605 and a second cavity 606, the second gear 702 drives the second rack 704 and the third rack 705 to move toward each other along the inner walls of the second cavity 606 and the first cavity 605. Sliding, the second rack 704 and the third rack 705 drive the two telescopic rods 703 to extend in opposite directions along the inner wall of the sliding sleeve 602, and the rotating nozzle 8 is installed at the end of the telescopic rod 703. At this time, the dust suppression range of the rotating nozzle 8 can be increased, and the operation efficiency is high. The sliding sleeve 602 completely penetrates the installation cover 601, which improves the stability of the rotating nozzle 8. The interior of the two telescopic rods 703 is separated by the second partition plate 706, and the wires and high-pressure water pipes inside the second column 402 are passed into the internal space of the two telescopic rods 703 through the wire holes 607 opened in the installation cover 601, which has strong flexibility.
