Description

Technical Field

[0001] This utility model relates to the field of fog cannon dust suppression technology, specifically to a fog cannon device for a dust suppression vehicle. Background Technology

[0002] With the rapid pace of urbanization and industrial development, dust pollution has become an increasingly serious problem. Dust suppression vehicles, as an important environmental protection device, play a crucial role in controlling dust and improving air quality. The mist cannon device is one of the core components of a dust suppression vehicle, and its performance directly affects the dust suppression effect.

[0003] Traditional dust suppression vehicle fog cannons have some shortcomings in practical applications. For example, the air outlet structure of some fog cannons is not well-designed, resulting in uneven airflow distribution and affecting the spray range and coverage. Others have poor atomization, producing large water mist particles that are difficult to effectively adsorb airborne particulate matter, thus reducing dust suppression efficiency. Furthermore, some fog cannons have limited adjustment functions, failing to flexibly change the spray direction and range according to different operating environments and needs, thus limiting their applicability. Utility Model Content

[0004] Based on the above-mentioned technical problems, this utility model proposes a fog cannon device for a dust suppression vehicle.

[0005] A fog cannon device for a dust suppression vehicle includes a duct. A drive unit is fixedly installed at the rear of the duct. An impeller is provided on the output shaft of the drive unit. A water guide coil is provided at the outlet of the front section of the duct. An atomizing nozzle is provided on the water guide coil. The front section of the duct is a cylindrical body that gradually decreases in size from back to front. The drive unit is installed inside an outer casing. Multiple circumferentially evenly distributed fixing rods are provided between the outer casing and the inner wall of the duct. A telescopic rod is provided at the rear end of the outer casing. The front end of the telescopic rod is connected and fixed to the tip of a cone. The cone does not contact the inner wall of the duct.

[0006] Preferably, the bottom plate of the cone has a sliding hole at its center, the inner wall of the front end of the air duct is provided with a fixing frame, the center of the fixing frame is provided with a sliding rod, the sliding rod passes through the sliding hole, and the sliding rod is coaxially arranged with the cone and the air duct.

[0007] Preferably, the telescopic rod is a hydraulic rod, and a plurality of circumferentially evenly spaced connecting rods are provided between the outer wall of the telescopic rod and the air duct.

[0008] Preferably, the diameter of the bottom of the cone is smaller than the diameter of the mist outlet at the front end of the air duct.

[0009] Beneficial effects: This utility model optimizes the structure of the air duct and adds an adjustable cone. By pushing or pulling the cone to move back and forth, the distance between the bottom of the cone and the inner wall of the air duct can be changed by changing the position of the cone inside the air duct. When the power of the driving device remains unchanged, the flow state of the airflow inside the air duct (flow becomes faster or slower) can be adjusted by changing the distance between the cone and the inner wall of the air duct, thereby achieving flexible control of the spray intensity. Attached Figure Description

[0010] Figure 1 A schematic diagram of the structure of this utility model is shown;

[0011] Figure 2 A cross-sectional view of the present invention is shown;

[0012] Figure 3 The internal structure diagram of this utility model is shown. Detailed Implementation

[0013] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0014] like Figures 1-3 The fog cannon device of the dust suppression vehicle shown is mainly composed of components such as air duct 1, drive device 2, impeller 3, water guide coil 4, and atomizing nozzle 5. The drive device 2 can be a drive motor.

[0015] The air duct 1 serves as the main structure of the entire device, providing installation space and airflow channels for the internal components. The drive unit 2, which is fixedly installed at the rear of the air duct 1, provides power for the rotation of the impeller 3. When the impeller 3 on the output shaft of the drive unit 2 rotates, it generates a strong wind, which propels the airflow forward and provides power support for the spraying of water mist.

[0016] The water guide coil 4 and atomizing nozzle 5 installed at the mist outlet at the front end of the air duct 1 are designed to convert water into fine water mist particles and spray the water mist out with the help of the wind generated inside the air duct 1 to achieve the effect of dust suppression.

[0017] The front section of the air duct 1 adopts a cylinder design that gradually decreases in size from back to front. This structure allows the airflow to gradually accelerate inside the air duct 1, increasing the wind speed at the mist outlet and enhancing the spray distance and coverage of the water mist.

[0018] The drive unit 2 is installed inside the outer casing 6. Multiple circumferentially evenly distributed fixing rods 7 are set between the outer casing 6 and the inner wall of the air duct 1. On the one hand, they protect the drive unit 2 and reduce interference and damage from external factors. On the other hand, the fixing rods 7 can firmly fix the outer casing 6 inside the air duct 1, ensuring the stability of the drive unit 2 during operation.

[0019] A telescopic rod 8 is provided at the rear end of the outer casing 6. The telescopic rod 8 is a hydraulic rod. Multiple circumferentially evenly distributed connecting rods 9 are provided between the outer wall of the telescopic rod 8 and the air duct 1 to enhance the stability and support of the telescopic rod 8. Its front end is connected and fixed to the tip of the cone 10. The function of the telescopic rod 8 is to push or pull the cone 10 to move back and forth. By changing the position of the cone 10 in the air duct 1, the distance between the bottom of the cone 10 and the inner wall of the air duct 1 can be changed. When the power of the drive device 2 remains unchanged, the flow state of the airflow in the air duct 1 (flow becomes faster or slower) can be adjusted by changing the distance between the cone 10 and the inner wall of the air duct 1, thereby achieving flexible control of the spray intensity. The cone 10 does not contact the inner wall of the air duct 1 to ensure that it can move freely under the action of the telescopic rod 8 and will not affect the adjustment effect due to friction with the inner wall of the air duct 1.

[0020] As a further improvement, the bottom plate 11 of the cone 10 has a sliding hole in the center, and a fixing frame 12 is provided on the inner wall of the front end of the air duct 1. A sliding rod 13 is provided in the center of the fixing frame 12. The sliding rod 13 passes through the sliding hole and is coaxially arranged with the cone 10 and the air duct 1 to ensure the stability and accuracy of the movement of the cone 10.

[0021] As a further improvement, the diameter of the bottom of the cone 10 is smaller than the diameter of the mist outlet at the front end of the air duct 1, so as to ensure that the air duct 1 can always output air normally.

[0022] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
