A discharge channel 13 is opened in the vertical rod 1, and the upper end of the discharge channel 13 is connected to the bottom of the dust collection bin 3. The lower end of the discharge channel 13 extends to the outside of the vertical rod 1 and is connected to an air bag 15. A dust collection module 14 is fixedly installed between the discharge channel 13 and the air bag 15, and a filter 16 is fixedly installed at the rear end of the air bag 15. A control module is fixedly installed on the vertical rod 1, and the control module is used to control the operation of various electronic parts.

[0032] During operation, the speaker 4 on the front side of the vertical pole 1 is aimed at the construction site, and the dust collection module 14 is started to suck the floating dust into the dust collection bin 3 and finally send it into the air bag 15.

[0033] A sensing component is arranged in the front opening of the speaker 4, and the sensing component is used to sense the size of solid particles contained in the dust. When it is sensed that the dust contains a large number of solid particles and the particles are large, the water delivery device 2 takes over the work of the dust collection bin 3.

[0034] The sensing component includes an elastic screen 41 and a plurality of tension detection units 42. The elastic screen 41 is spider web-shaped. The tension detection units 42 are fixedly installed at equal distances on the inner wall of the front opening of the speaker 4. The end of the elastic screen 41 is fixedly connected to the working end of the tension detection unit 42. A film 43 is fixedly sewn at the gap of the elastic screen 41. The film 43 has a plurality of small holes. The elastic screen 41 and the film 43 cooperate to prevent large solid particles in the dust from entering the exhaust passage 13, thereby preventing the large solid particles from blocking the exhaust passage 13.

[0035] Working principle: The dust generated by construction contains solid particles, which are sucked into the airbag 15. Large solid particles fall on the elastic screen 41, and the elastic screen 41 droop tension detection unit 42 detects the value. If there are more solid particles and the volume is larger, the larger the measured value is, when the measured value reaches the preset range, the water delivery device 2 replaces the dust suction module 14 to work, and water is sprayed from the nozzle 21 in the form of water mist, and the water mist absorbs the dust, so as to prevent the dust from spreading.

[0036] A docking port 31 is fixedly installed at the bottom of the dust collection bin 3, and the docking port 31 is connected to the discharge channel 13. A motor-driven sponge roller 33 is pivotally connected in the dust collection bin 3, and the sponge roller 33 is located behind the docking port 31. A discharge pipe 32 is fixedly installed at the rear end of the dust collection bin 3, and a small electric push rod 34 is fixedly installed on the top of the dust collection bin 3. The movable end of the small electric push rod 34 extends into the dust collection bin 3 and contacts the sponge roller 33.

[0037] The end of the discharge pipe 32 away from the dust collection bin 3 is bent vertically downward and hinged with a flap 36. The front end of the flap 36 extends forward and is welded with a spring 37. The end of the spring 37 away from the flap 36 is welded to the body of the spring 37.

[0038] A slope 35 is welded at the bottom of the inner wall of the dust collection bin 3, and the front section of the slope 35 is higher than the rear section.

[0039] In order to protect the exhaust passage 13, a mesh screen is placed at the docking port 31. Figure 5 , the dust is sucked into the dust collection bin 3, carrying some large solid particles, which fall on the slope 35 and slide along the slope 35 to the sponge roller 33. After a period of time, the suction stops, the small electric push rod 34 shrinks, the motor 17 winds the steel wire 18, and drives the flap 36 to rotate, so that the lower end of the discharge pipe 32 is connected to the outside world. Then the sponge roller 33 rotates and sweeps the solid particles into the discharge pipe 32. In this way, the larger solid particles in the dust collection bin 3 are removed. Avoid the accumulation of larger solid particles in the dust collection bin 3.

[0040] A hollow cylinder 22 is fixedly installed in the nozzle 21, and a plurality of water outlets 23 are opened on the front of the cylinder 22, and a water inlet 24 is opened on the back of the water delivery device 2. The plurality of water outlets 23 are divided into three rows: upper, middle and lower.

[0041] The angle between two adjacent rows of water outlets 23 is 30°, and the angle between two adjacent rows of baffles 26 is 30°. The baffles 26 correspond to the water outlets 23 one by one, and the baffles 26 can cover the water outlets 23. By adjusting the angle of the shaft 25, the water outlet of any row or multiple rows of water outlets 23 can be controlled to achieve the purpose of controlling the water output.

[0042] The upper hoop 5 and the lower hoop 6 are fixedly installed on the shaft of the vertical rod 1 from top to bottom, and a rope 8 is connected to the side of the upper hoop 5. A hook lock 9 is fixedly tied to the end of the rope 8 away from the upper hoop 5. The hook lock 9 is threadedly connected to a screw 91, and a support leg 61 is welded on the outer side of the lower hoop 6. The hook locks 9 between adjacent vertical rods 1 are buckled together, so that two adjacent vertical rods 1 can be connected together, and the vertical rods 1 are surrounded in a circle around the construction site, thereby increasing the effect of suppressing dust and expanding the scope of suppressing dust.

[0043] There is a raised portion 51 on the side of the upper hoop 5, and the raised portion 51 is plugged with a sleeve 7, and the sleeve 7 is pivoted with a rotating rod 71, and the shaft of the rotating rod 71 vertically penetrates the sleeve 7, and the end of the rope 8 away from the hook lock 9 extends into the sleeve 7 and is fixedly tied to the rotating rod 71.

[0046] When the device is working, the electromagnet module 54 is powered on to generate a magnetic field, and the sleeve 7 is attracted by magnetic force. When a single vertical rod 1 is tilted due to external force, the values ​​measured by the tension detectors 52 on both sides of the vertical rod 1 change too much, and the electromagnet module 54 is powered off and has no magnetic force. At this time, even if the vertical rod 1 tilts, the sleeve 7 is directly pulled out from the raised part 51 without involving other vertical rods 1.

[0047] A base 11 is welded on the back of the vertical rod 1, a support rod 12 is welded on the bottom of the base 11, and a water storage bucket 10 is fixedly installed on the top of the base 11. The water storage bucket 10 is used to connect with the water delivery device 2.

Dust is suppressed by this vacuum dust suction method. A sensing component is provided in the speaker 4, and the sensing component is composed of an elastic blocking net 41, a tension detection unit 42, and a film 43. Whether there are many large solid particles in the dust is detected by sensing the extension. And when there are many large solid particles, the water delivery device 2 is used to replace the dust collecting bin 3 to suppress dust by sprinkling water. It serves the purpose of protecting local components.

[0049] In addition, the shaft of the vertical rod 1 is connected with an upper hoop 5, and the side of the upper hoop 5 is connected with a hook lock 9, a sleeve 7, a rotating rod 71, a volute spring 72, and a rope 8.
