[0039] Continue to refer to Figure 3 , in this embodiment, a processing unit 13 for filtering impurities in the liquid water is provided in the mobile water tank 10. The processing unit 13 is arranged on the inner bottom plate of the mobile water tank 10. The end of the water inlet pipe away from the water pump 11 is inserted into the processing unit 13. The liquid water in the mobile water tank 10 enters the water inlet pipe through the processing unit 13. By providing the processing unit 13, the impurities in the liquid water are prevented from blocking the atomizing nozzle 212.

[0040] Continue to refer to Figure 3 and Figure 4 , in this embodiment, the processing unit 13 includes a processing box 131, a control valve 132, and a sealing plate 133. An installation opening is provided on the outer side wall near the bottom end of the mobile water tank 10. The installation opening is communicated with the inner cavity of the mobile water tank 10. An opening 1312 is provided on one side of the processing box 131. The opening 1312 is communicated with the inner cavity of the processing box 131. The processing box 131 is arranged on the inner bottom plate of the mobile water tank 10. The installation opening is communicated with the inner cavity of the processing box 131 through the opening 1312. The sealing plate 133 is detachably installed on the opening 1312 to make the processing box 131 in a closed state. A filter screen 1311 is arranged in the processing box 131. The outer wall of the filter screen 1311 is connected to the inner wall of the processing box 131. The end of the water inlet pipe away from the water pump 11 is inserted into the processing box 131 through the top end of the processing box 131. The end of the processing box 131 away from the opening 1312 is connected to the control valve 132 through a connecting pipe 134. When the water pump 11 pumps water, the control valve 132 is in an open state. The liquid water in the mobile water tank 10 flows into the processing box 131 through the control valve 132 and the connecting pipe 134 in sequence, and enters the water inlet pipe through the filter screen 1311. By providing the filter screen 1311, the impurities in the water are prevented from being sucked into the water pump 11 and the atomizing nozzle 212 to cause blockage.

[0041] Specifically, one end of the water inlet pipe facing away from the water pump 11 is inserted into the treatment tank 131 and is located between the inner top wall of the treatment tank 131 and the filter screen 1311.

[0042] Among them, the sealing cover plate 133 and the treatment tank 131 are bolted together. Of course, the sealing cover plate 133 and the treatment tank 131 can also be connected by plugging and unplugging.

[0043] When the dust reduction device 1 provided in this embodiment performs dust reduction, the output shaft of the waterproof motor 221 drives the driving gear 222 to rotate. The rotation of the driving gear 222 drives the driven gear 223 to rotate. The driven gear 223 drives the water delivery pipe 211 to rotate, and the water delivery pipe 211 drives the atomizing nozzle 212 to rotate. Start the water pump 11, and the water pump 11 pumps the liquid water in the mobile water tank 10 into the treatment tank 131 through the control valve 132 and the connecting pipe 134 in sequence, and pumps it into the water inlet pipe through the filter screen 1311, and then transports it to the atomizing nozzle 212 through the water outlet pipe, the water collecting box 32 and the water delivery pipe 211. The atomizing nozzle 212 sprays the water mist in a circumferential rotation manner, and start the fan 23. The wind generated by the fan 23 is blown out through the communicating pipe 233 to increase the spraying range of the atomizing nozzle 212 and improve the dust reduction efficiency.

[0044] When the dust reduction spraying stops, close the control valve 132 to block the treatment tank 131, prevent the liquid water in the mobile water tank 10 from entering the treatment tank 131, and at the same time prevent the water in the treatment tank 131 from flowing into the mobile water tank 10. Then, the sealing cover plate 133 on the other side of the treatment tank 131 can be opened to clean the impurities filtered in the treatment tank 131.

[0045] Continue to refer to Figure 1 , in this embodiment, a plurality of pairs of lifting components 15 are arranged on the outer peripheral wall near the bottom end of the mobile water tank 10, and the plurality of pairs of lifting components 15 are arranged at intervals along the first direction 40 of the mobile water tank 10; by arranging the plurality of pairs of lifting components 15, thus, it is convenient to fix the mobile water tank 10 on the uneven roadside.

[0046] It should be noted that the first direction 40 of the mobile water tank 10 is the length direction of the mobile water tank 10, the second direction 50 of the mobile water tank 10 is the width direction of the mobile water tank 10, the third direction 60 of the mobile water tank 10 is the height direction of the mobile water tank 10, and the first direction 40, the second direction 50 and the third direction 60 of the mobile water tank 10 are perpendicular to each other in pairs.

[0047] As Figure 1 shown, in this embodiment, the number of the lifting components 15 is two pairs. Of course, the number of the lifting components 15 can also be three pairs or four pairs.

[0048] Among them, it should be noted that each pair of lifting components 15 includes two lifting components 15 arranged oppositely along the second direction 50 of the moving water tank 10.

[0049] Furthermore, in this embodiment, the lifting component 15 includes a fixed block 234 (fixed block 234151), a screw rod 152, and a support plate 153. One end of the fixed block 234 (fixed block 234151) is connected to the outer wall near the bottom end of the water tank, and the other end of the fixed block 234 (fixed block 234151) extends outward along the second direction 50 of the moving water tank 10. A threaded hole is formed in the fixed block 234 (fixed block 234151), and the threaded hole extends along the third direction 60 of the moving water tank 10 and penetrates the fixed block 234 (fixed block 234151). The bottom end of the screw rod 152 passes through the threaded hole and is connected to the support plate 153. The screw rod 152 is threadedly connected to the fixed block 234 (fixed block 234151), and the screw rod 152 can move relative to the fixed block 234 (fixed block 234151); by rotating the screw rod 152, the screw rod 152 drives the support plate 153 to move.

[0050] Specifically, the central axis of the screw rod 152 is arranged parallel to the third direction 60.

[0051] When the moving water tank 10 moves to a preset position, rotate the screw rod 152, and the screw rod 152 drives the support plate 153 to move downward, so that the bottom surface of the support plate 153 abuts against the ground, thereby adjusting the posture of the moving water tank 10, enabling the moving water tank 10 to be placed stably on a potholed and uneven road surface and preventing it from tilting and falling.

[0052] Furthermore, in this embodiment, a turntable 154 is provided at the top end of the screw rod 152. A plurality of push rods 1541 are provided on the outer peripheral wall of the turntable 154. One ends of the plurality of push rods 1541 are all connected to the outer peripheral wall of the turntable 154, and the other ends of the plurality of push rods 1541 all extend radially outward along the turntable 154. The plurality of push rods 1541 are arranged at intervals along the circumferential direction of the turntable 154; by providing the plurality of push rods 1541, the screw rod 152 can be twisted more conveniently.

[0053] In order to improve the comfort of the operator, a soft sleeve is sleeved on each push rod 1541.

[0054] During use, push the push rod 1541, and the push rod 1541 drives the screw rod 152 to rotate through the turntable 154. The screw rod 152 moves upward or downward along the threaded hole, and the movement of the screw rod 152 drives the support plate 153 to move.

[0055] Furthermore, in this embodiment, a viewing port is formed on the outer wall of the moving water tank 10. The viewing port is communicated with the inner cavity of the moving water tank 10, and a viewing window 16 is installed on the viewing port; by providing the viewing window 16, it is convenient to check the remaining water in the moving water tank 10, so as to add and supplement it in time.

[0056] Specifically, taking the Figure 1 shown orientation as an example, visual ports are provided on both the front wall and the rear wall of the mobile water tank 10. Each visual port communicates with the inner cavity of the mobile water tank 10, and a visual window 16 is installed on each visual port.

[0057] Among them, a control panel 17 electrically connected to the water pump 11, the waterproof motor 221, the fan 23, and the control valve 132 is installed on the outer wall of the mobile water tank 10. A waterproof box 18 is installed on the outside of the control panel 17, and the waterproof box 18 encloses the control panel 17 inside. On the one hand, by setting the control panel 17, it is convenient to centrally control the water pump 11, the waterproof motor 221, the fan 23, and the control valve 132. On the other hand, by setting the waterproof box 18, it is avoided that the control panel 17 contacts the water mist and fails during the dust suppression spraying.

[0058] The working process of the dust suppression device 1 provided in this embodiment is as follows: The water pump 11 is started to generate suction to suck the liquid water in the mobile water tank 10 into the treatment tank 131 and filter it through the filter screen 1311. The filtered water is then transported by the water pump 11 through the water outlet pipe, the water collecting box 32, and the water supply pipe 211 to the atomizing nozzle 212. At the same time, the waterproof motor 221 is started. The output shaft of the waterproof motor 221 drives the driving gear 222 to rotate. The driving gear 222 rotates to drive the driven gear 223 to rotate. The driven gear 223 drives the water supply pipe 211 to rotate, and the water supply pipe 211 drives the atomizing nozzle 212 to rotate, so that the atomizing nozzle 212 sprays the water mist in a circumferential rotation manner to the location of the building construction for dust suppression, and the fan 23 is started. The wind generated by the fan 23 is blown out through the connecting pipe 233 to increase the spraying range of the atomizing nozzle 212 and improve the dust suppression efficiency.
