[0002] With social development and the advancement of urbanization, more and more buildings are springing up. Construction processes such as lime and cement raise a lot of dust. Various factories have started production, and the smoke and dust emitted into the atmosphere have a great impact on the environment. Moreover, the wind will carry the dust and smoke into the city, affecting the urban environment. Dust floating in the air has become one of the main pollutants in the city.

[0003] A search revealed a patent with authorization announcement number CN 218924187 U, which discloses a dust suppression device for environmental protection. The device includes a base, a primary support fixedly installed at the top of the base, a secondary support inserted through the top of the primary support, a support plate hinged to the top of the secondary support, a turntable installed at the top of the support plate, a nozzle fixedly installed on the outer side of the turntable, a water inlet pipe installed at the bottom of the support plate, a transition pipe installed at the top of the support plate, and an adjustment mechanism provided at the bottom of the support plate. The adjustment mechanism includes a guide block, an inclined support, a secondary support, and a primary support, with the guide block slidably sleeved on the outer side of the secondary support.

[0004] Although the dust suppression range can be adjusted by adjusting the tilt angle and height of the turntable, the device has a fixed position and can only suppress dust in the area where it is placed, which has poor flexibility. Therefore, in order to solve the aforementioned problems, we propose a dust suppression device for environmental protection. Utility Model Content

[0005] The purpose of this utility model is to address the deficiencies in the existing technology by proposing an environmental protection dust suppression device.

[0014] When dust suppression is needed in a certain area, clean water can be loaded into a water tank. Then, a drone can be launched to carry the water tank to the airspace above the area. The spraying components can then spray the area from the air to suppress dust. The drone can also land at a high altitude and use the spraying components to spray a large area of ​​dust at a fixed location.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model;

[0023] Reference Figure 1-4 An environmental protection dust suppression device includes a drone 1. A water tank 2 is fixedly installed on the bottom of the drone 1. A spraying assembly 3 is fixedly installed on the lower side of one side of the water tank 2. A bracket 4 is fixedly installed on the bottom of the water tank 2. The spraying assembly 3 includes a mounting frame 11, which is fixedly installed on the lower side of one side of the water tank 2. A lead screw 9 is rotatably installed between the left and right sides inside the mounting frame 11. The lead screw 9 is a bidirectional lead screw. The outer surface of the lead screw 9 is provided with two symmetrical threads with opposite textures. A drive motor 20 is fixedly installed on one side of the mounting frame 11. The output end of the drive motor 20 is connected to the lead screw 9. Mounting blocks 12 are threaded on both sides of the lead screw 9. A spray pipe 18 is rotatably installed inside the front end of the mounting block 12. A connecting hose 14 is fixedly connected to one end of the spray pipe 18. One end of the connecting hose 14 is connected to the inside of the water tank 2. Multiple atomizing nozzles 19 are fixedly installed at equal intervals on the outer surface of the spray pipe 18.

[0024] When dust suppression is needed in a certain area, clean water can be loaded into water tank 2. Then, drone 1 is started to carry water tank 2 to the airspace above the area. After that, the area can be sprayed with water from the air by spraying component 3. Through the above process, dust suppression can be carried out more comprehensively in the area, allowing water mist to spread over a wide area, adsorbing more dust and improving the dust suppression effect.

[0025] Drone 1 can be an existing industrial drone, which has a good payload capacity and is suitable for long-term and large-scale work.

[0026] The drive motor 20 of the spray assembly 3 can drive the lead screw 9 to rotate. After the lead screw 9 rotates, it can drive the two spray pipes 18 to move laterally through the two sections of threads on the surface and the mounting block 12. The two spray pipes 18 can move in opposite directions at the same time or in opposite directions at the same time, which can change the spray range.

[0027] Limiting rods 10 are fixedly installed between the left and right sides inside the mounting bracket 11. The rear end of the mounting block 12 is slidably installed on the outer surface of the limiting rods 10. The limiting rods 10 can limit the mounting block 12, so that the mounting block 12 can only move in a straight line, and prevent the mounting block 12 from rotating with the lead screw 9 under the action of friction.

[0028] A second gear 17 is fixedly mounted on the outer surface of the spray pipe 18. A rotary motor 15 is fixedly mounted on the top of the mounting block 12. A first gear 16 is fixedly mounted on the output end of the rotary motor 15. The first gear 16 meshes with the second gear 17. The rotary motor 15 can drive the first gear 16 to rotate, and the first gear 16 can drive the spray pipe 18 to rotate through the second gear 17, thereby changing the spraying direction of the spray pipe 18. The rotary motor 15 can be a stepper motor, which can precisely control the rotation angle of the spray pipe 18.

[0029] A solenoid valve 13 is fixedly installed inside the spray pipe 18 on the side near the connecting hose 14. The solenoid valve 13 can control the water flow rate into the spray pipe 18, thereby facilitating the control of the start and stop of the spray.

[0030] A water inlet 8 is fixedly installed on one side of the water tank 2, and an air pump 5 is fixedly installed on one side of the water tank 2. An air pump 5 is fixedly installed at the air outlet end of the air pump 5. One end of the air pump 5 is connected to the inside of the water tank 2, and a one-way valve 7 is fixedly installed inside the air pump 6.

[0031] Clean water can be added to the water tank 2 through the water inlet 8. The air pump 5 can inflate the water tank 2 through the air inlet 6 to increase the internal pressure of the water tank 2, thereby increasing the water pressure so that the clean water has sufficient pressure to be sprayed out through the spray pipe 18. The one-way valve 7 can prevent the clean water from flowing back into the air pump 5.
