[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] Reference Figure 1-6The utility model discloses a dust control device, comprising a storage box 1, a moving wheel 101 is arranged at the bottom of the storage box 1, a lifting mechanism 2 and a spray device 3 are arranged on the storage box 1, the spray device 3 is installed on the storage box 1 in a lifting manner through the lifting mechanism 2, a soft water bag 8 is arranged inside the storage box 1, a connecting pipe 7 is connected to the soft water bag 8, the connecting pipe 7 comprises a water inlet pipe, a water delivery pipe connecting the soft water bag 8 and the spray device 3, a negative pressure pipe connecting the soft water bag 8 and the negative pressure mechanism, an external water supply pipe is connected to the spray device 3, and valves are installed on the water inlet pipe, the water delivery pipe, the negative pressure pipe and the external water supply pipe.

[0028] The interior of the storage box 1 is a hollow structure with an opening at the top. The lifting plate 102 is installed in the storage box 1 in a vertically movable manner. One end of the negative pressure pipe, the water inlet pipe, and the water delivery pipe are all connected to the bottom of the soft water bag 8. The soft water bag 8 can be made of rubber or Oxford cloth with an oil-coated waterproof coating. The bottom of the soft water bag 8 is adhesively connected to the bottom of the inner side of the storage box 1. When in use, the lifting mechanism 2 drives the spray device 3 to rise or fall. The soft water bag 8 is filled with water for dust control after the spray device 3 is raised. When the spray device 3 needs to be stored in the storage box 1, the water in the soft water bag 8 at the spraying location is first extracted through the spray device 3, and then the air in the soft water bag 8 is extracted, so that the soft water bag 8 is fit and stored at the bottom of the storage box 1, and finally the spray device 3 is driven by the lifting mechanism 2 to be stored in the storage box 1.

[0029] The spray device 3 includes a turntable 6, on which a bracket 5 is provided, on which a fog cannon 4 is rotatably provided, and the fog cannon 4 includes a spray mechanism 10. One end of a water pipe is connected to a soft water bag 8, and the other end is connected to the spray mechanism 10. The spray mechanism 10 is also connected to an external water supply pipe.

[0030] The turntable 6 drives the bracket 5 and the fog cannon 4 to rotate in the horizontal direction to adjust the horizontal orientation of the fog cannon 4. The fog cannon 4 is installed on the bracket 5 in a vertical direction. The fog cannon 4 is rotated in the vertical direction to adjust the pitch angle of the fog cannon 4. The spray mechanism 10 includes a nozzle and a gear pump (not shown in the figure). The gear pump draws water and pressurizes it to spray water mist through the nozzle. When it starts to be used, the gear pump draws water through an external water supply pipe (not shown in the figure). When the spraying operation is nearing the end, the valve on the external water supply pipe is closed, and the valve on the water inlet pipe is opened. The spray mechanism 10 draws water from the soft water bag 8 through the water inlet pipe.

[0031] The fog cannon 4 includes a cylinder 9, a spray mechanism 10 is provided at one end of the cylinder 9, an axial flow fan 12 is provided on the side of the cylinder 9 away from the spray mechanism 10, the negative pressure mechanism includes a negative pressure through hole 14 penetrating through the cylinder 9, the negative pressure through hole 14 is located between the spray mechanism 10 and the axial flow fan 12, one end of the negative pressure tube is connected to the soft water bag 8, and the other end is connected to the negative pressure through hole 14.

[0032] When the airflow blown by the axial flow fan 12 passes over the negative pressure through hole 14, the air pressure above the negative pressure through hole 14 is less than the air pressure inside the negative pressure through hole 14, forming a suction effect on the negative pressure through hole 14. When the water in the soft water bag 8 is used up, the valve on the water inlet pipe is closed, and the valve on the negative pressure pipe is opened. The airflow blown by the axial flow fan 12 is used to suck out the air in the soft water bag 8. The principle is similar to that of a jet pump. Under the action of the external atmospheric pressure, the soft water bag 8 is flattened and stored at the bottom inside the storage box 1.

[0033] The negative pressure mechanism also includes a flow guide cover 13, which is in the shape of an arc-shaped tile. The axis of the flow guide cover 13 is parallel to the axis of the cylinder 9. The flow guide cover 13 is located directly above the negative pressure through hole 14. The flow guide cover 13 and the cylinder 9 enclose a negative pressure channel, and the top of the negative pressure through hole 14 is connected to the negative pressure channel.

[0034] The air guide cover 13 reduces the dust in the external environment from falling into the negative pressure through hole 14 without hindering the normal flow of the airflow blown out by the axial flow fan 12 .

[0035] The opening area of ​​the negative pressure channel on the side close to the axial flow fan 12 is larger than the opening area on the side close to the spray mechanism 10 .

[0036] The negative pressure channel is formed into a trumpet-like shape. According to Bernoulli's principle, air enters the negative pressure channel from a large opening and then flows out from a small opening, so that the air flow velocity is further increased, thereby improving the suction effect of the negative pressure channel on the negative pressure through hole 14.

[0037] A flow balancing plate 11 is arranged between the spray mechanism 10 and the axial flow fan 12 . The cross-sections of the plurality of flow balancing plates 11 are in a “M” shape. The negative pressure through hole 14 is located between two adjacent flow balancing plates 11 .

[0038] The flow equalizing plate 11 is arranged along the axial direction of the cylinder 9, and is distributed in a "M" shape with the axis of the cylinder 9 as the center, so that the airflow blown out by the axial flow fan 12 is evenly distributed. The part where the cylinder 9 and the flow equalizing plate 11 are connected is a truncated cone. At this position, the opening area of ​​the cylinder 9 close to the axial flow fan 12 is larger than the opening area on the side of the spray mechanism 10, so that a structure with a large opening at one end and a small opening at the other end is formed between the cylinder 9 and the air guide cover 13.

[0039] The lifting mechanism 2 includes a lifting plate 102 , a turntable 6 is installed on the top of the lifting plate 102 , electric push rods are arranged around the lifting plate 102 , four electric push rods are installed at the four corners of the storage box 1 , and the working ends of the electric push rods are connected to the lifting plate 102 .

[0040] When in use, the electric push rod is started, and the working end of the electric push rod is extended or retracted, driving the lifting plate 102 to rise or retract from the inner side of the storage box 1, and further driving the spray device 3 to rise or retract.

[0041] Working principle: When in use, start the lifting mechanism 2 to drive the spray device 3 to rise from the storage box 1, then open the valve on the water inlet pipe, fill the soft water bag 8 with water through the water inlet pipe, close the valve on the water inlet pipe, connect the external water supply pipe with the external water source, open the valve on the external water supply pipe, start the spray device 3, the spray mechanism 10 sprays water mist, the axial flow fan 12 blows out airflow, sprays the water mist to a distance for dust control, when the spraying work is about to end, close the valve on the external water supply pipe, open the valve on the water delivery pipe, extract the water in the soft water bag 8 through the spray mechanism 10 and spray it out, after the water in the soft water bag 8 is used up, close the valve on the water delivery pipe, open the valve on the negative pressure pipe, at this time, the airflow blown by the axial flow fan 12 passes through the negative pressure channel, the negative pressure channel extracts the air in the soft water bag 8 through the negative pressure through hole 14 and the negative pressure pipe, the soft water bag 8 is flattened, and the lifting mechanism 2 is controlled to drive the spray device 3 to be retracted into the storage box 1.
