[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Reference Figures 1-2 , Figure 7 This utility model provides an embodiment of a small dust suppression device for highway construction, including a base 1. The base 1 serves as the basic support structure for the entire device, providing a stable placement platform to ensure that the device will not easily shake or shift during use, thus guaranteeing stable operation. An electric turntable 2 is rotatably connected to the top of the outer surface of the base 1. The electric turntable 2 allows the device to rotate horizontally, and its working direction can be flexibly adjusted through electric control to expand the dust suppression coverage area and meet the dust suppression needs of different construction scenarios. A support frame 4 is fixedly connected to the top of the outer surface of the electric turntable 2. The support frame 4 supports and fixes important components such as the mist cannon 6, firmly installing it on the electric turntable 2 to ensure that the mist cannon 6 will not shift its position due to its own vibration or other factors during operation, thus ensuring the overall structural stability of the device. An angle adjustment component 9 is provided on the top of the inner surface of the support frame 4. The angle adjustment component 9 includes a rotating shaft 901, which is a key component for adjusting the angle of the fog cannon 6. Through its rotatable connection with the support frame 4, the fog cannon 6 can be adjusted vertically around the rotating shaft 901, thereby changing the spray direction of the fog cannon 6 and enabling dust suppression operations at different heights. The outer surface of the rotating shaft 901 is rotatably connected to the top of the inner surface of the support frame 4, so that the rotating shaft 901 can always rotate the fog cannon 6 along a designated position on the support frame 4. The fog cannon 6 is fixedly connected to the outer surface of the rotating shaft 901. As the main dust suppression component, the fog cannon 6 diffuses the water mist sprayed by the spray ring 7 into the air, adsorbs and settles the dust particles in the air, and achieves the purpose of dust suppression, effectively improving the air quality of the construction area.

[0036] Reference Figures 3-4 , Figure 6 A spray ring 7 is fixedly connected to the outer surface of the fog cannon 6 via a support column 18. The support column 18 connects and supports the spray ring 7, ensuring its stable installation on the fog cannon 6 and enabling it to work in conjunction with the fog cannon 6. This also ensures the stability of the spray ring 7 during operation. A protective ring 8 is rotatably connected to the outer surface of the spray ring 7, allowing it to rotate along the surface of the spray ring 7. A nozzle 19 is fixedly connected to the outer surface of the spray ring 7. The nozzle 19 is the component that converts water into water mist, evenly distributed on the spray ring 7. It sprays the water supplied by the water pump 3 in a mist form, increasing the contact area between the water mist and the air, thus improving dust suppression efficiency. Spray holes 20 are formed on the outer surface of the protective ring 8 to protect the nozzle 19 from damage. When in use, the device can protect the nozzle 19. Through cooperation with the nozzle 19, water mist can only be sprayed when the nozzle 20 is aligned with the nozzle 19. When not in use, the nozzle 19 is covered to protect it. The outer surface of the protective ring 8 is fixedly connected to the traction member 13, which is used to drive the protective ring 8 to rotate. The front end of the outer surface of the fog cannon 6 is fixedly connected to the limiting plate 10. The outer surface of the traction member 13 and the inner surface of the limiting plate 10 are connected through and slidably connected. The limiting plate 10 plays a role in limiting and positioning, providing guidance and limiting for the sliding of the traction member 13, ensuring that the traction member 13 will not leave the predetermined track during the sliding process, and also providing a locking position for the locking block 15 to ensure that the position of the protective ring 8 is fixed.

[0037] Reference Figure 2 , Figure 7 The angle adjustment component 9 also includes a knob 902. A threaded sleeve 904 is threaded through and connected to the rear of the outer surface of the knob 902, allowing the knob 902 to always move axially to a designated position within the threaded sleeve 904. The outer surface of the threaded sleeve 904 is threaded through and fixedly connected to the inner surface of the fog cannon 6. When the knob 902 moves the threaded sleeve 904 in an arc, it simultaneously causes the fog cannon 6 to rotate along the support frame 4, thereby adjusting the spray angle of the fog cannon 6. The support frame 4... An arc-shaped groove 903 is provided on the top of the outer surface of the knob 902. The arc-shaped groove 903 provides a track for the sliding of the knob 902. Its arc design is adapted to the rotation angle of the fog cannon 6, ensuring that the knob 902 can slide along a predetermined trajectory during the adjustment of the angle. The outer surface of the knob 902 and the inner surface of the arc-shaped groove 903 are connected and slidably connected. When the knob 902 is tightened, the friction generated by the contact between the knob 902 and the outer surface of the arc-shaped groove 903 can fix the fog cannon 6 at a specified angle.

[0038] Reference Figures 2-4A handle 14 is hinged to the front end of the inner surface of the fog cannon 6, allowing the handle 14 to move in an arc along a designated position within the fog cannon 6. The outer surface of the traction member 13 is hinged and slidably connected to the inner surface of the handle 14, allowing the handle 14 to move in an arc along a designated position, thereby driving the traction member 13 to move in a larger arc along that designated position. A telescopic member 12 is elastically connected to the outer surface of the handle 14 via a spring 16, allowing the telescopic member 12 to move without being affected by external forces. The telescopic member 12 is always close to the handle 14. The outer surface of the telescopic member 12 is fixedly connected to the locking block 15, so that when the telescopic member 12 moves along the right side of the handle 14, the locking block 15 can move together. The outer surface of the limiting plate 10 is provided with a locking groove 11. The outer surface of the limiting plate 10 is engaged with the inner surface of the locking groove 11. The locking block 15 cooperates with the locking groove 11 to fix the position of the protective ring 8. When the locking block 15 is engaged in the locking groove 11, the protective ring 8 is locked in the current position to prevent it from rotating due to vibration or other factors during operation.

[0039] Reference Figures 1-2 , Figure 5 A water pump 3 is fixedly connected to the top of the outer surface of the base 1. The water pump 3 provides power to the equipment, draws water from the water source and delivers it to the spray ring 7 and the mist cannon 6 through the hose 5, providing sufficient water pressure to the nozzle 19 and the mist cannon 6 to ensure that the water mist can be sprayed out at an appropriate speed and range to achieve effective dust suppression. The output end of the water pump 3 is fixedly connected to the bottom of the outer surface of the spray ring 7 through the hose 5. The hose 5 has a certain degree of flexibility and can adapt to the position changes of the equipment during angle adjustment and rotation without affecting the connection between the water pump 3 and the spray ring 7, ensuring that water can be smoothly delivered from the water pump 3 to the spray ring 7. One end of the spring 16 is fixedly connected to the outer surface of the handle 14, and the other end of the spring 16 is fixedly connected to the inner surface of the telescopic member 12, so that the telescopic member 12 can always drive the locking block 15 to engage with the locking groove 11 under the elastic force of the spring 16, so as to keep the protective ring 8 in the designated position.

[0040] Reference Figures 1-2 , Figure 6 The outer surface of the protective ring 8 has a through groove 17 at the rear end. The inner surface of the through groove 17 is connected to the outer surface of the support column 18. The through groove 17 provides sliding space for the protective ring 8, so that the protective ring 8 will not be blocked by the support column 18 when it rotates around the spray ring 7, ensuring the smooth rotation of the protective ring 8. At the same time, it also plays a certain role in limiting the rotation of the protective ring 8. The outer surface of the water pump 3 is fixedly connected to a housing. The housing is used to protect the water pump 3 and prevent external dust, debris and other objects from entering the water pump 3 and avoiding affecting the normal operation of the water pump 3.

[0041] Working principle: When using the dust suppression equipment, first pull the telescopic component 12 outward to cause the locking block 15 to disengage from the slot 11. Then pull the telescopic component 12 downward so that when it rotates along the inside of the fog cannon 6 via the handle 14, it can simultaneously drive the traction component 13 to move in a circle. When the traction component 13 moves in a circle, it will simultaneously drive the protective ring 8 to rotate along the outer surface of the spray ring 7, so that the spray hole 20 on the protective ring 8 is aligned with the nozzle 19 on the spray ring 7, so that the spray from the nozzle 19 can spray in front of the fog cannon 6. Then release the telescopic component 12 so that it retracts inward under the elastic force of the spring 16, so that the locking block 15, driven by the telescopic component 12, is always locked with the slot 11 without external force, so that the protective ring 8 can always be kept in the designated position. Then start the water pump 3 and the fog cannon 6 to diffuse the sprayed water mist into the working area.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
