Description

TECHNICAL FIELD

[0001] The present application belongs to the field of dust suppression vehicles, and particularly relates to a multifunctional dust suppression vehicle capable of omnidirectional spraying. BACKGROUND

[0002] In the field of environmental governance and urban cleaning, dust suppression vehicles, as an important equipment, are widely used in roads, construction sites and other places to reduce dust particles in the air and improve air quality through spraying water mist. Most of the dust suppression vehicles on the market are equipped with spraying devices, such as fog cannons, which mainly function to spray water mist into the air after atomization, combining with dust to make it settle.

[0003] However, the spraying devices of the existing dust suppression vehicles have some obvious deficiencies. First, the current spraying system usually cannot flexibly adjust the spraying range. This means that the spraying machine can only effectively cover the area at a certain distance from it, i.e. the far end of the spraying range, while the area close to the spraying machine is often ineffective or even cannot be covered. This fixed spraying mode limits the application scenarios and efficiency of the dust suppression vehicle. For example, when the dust suppression vehicle needs to work on a narrow road or needs to spray water mist close to a specific dust raising point (such as a material storage site), the existing fixed spraying mode is not satisfactory, either failing to accurately cover the target area or causing local water accumulation due to too concentrated water mist, which in turn affects the work effect. Even worse, when different distances of targets need to be dusted, the operator often has to adjust the vehicle's driving speed and distance to adapt, which is inefficient and difficult to ensure the spraying effect.

[0004] Secondly, the current mainstream fog cannon technology mostly uses an axial flow fan as the air supply mechanism. The axial flow fan accelerates air flow through rotating blades to generate high-speed airflow and push out the atomized water droplets. The speed of the airflow directly determines the spraying distance of the water mist. In order to improve the spraying distance, the existing technology mainly relies on increasing the speed of the fan or increasing the installation angle of the blades. Increasing the speed means that the fan motor needs to consume more electric energy to overcome air resistance, resulting in a significant increase in energy consumption. At the same time, the friction between the high-speed rotating blades and the air generates strong aerodynamic noise, which is more prominent when the speed is high, seriously affecting the tranquility of the surrounding environment and even possibly causing damage to the operator's hearing. Increasing the installation angle of the blades also increases the interaction force between the fan blades and the air, which can increase the wind speed to some extent, but also increases the load of the motor and energy consumption, and also generates noise. In some places with high environmental protection requirements, such as urban centers, schools and hospitals, the use of dust suppression vehicles with high energy consumption and high noise will be strictly limited. In addition, frequently operating the fan at high power will also shorten the service life of the equipment and increase the maintenance cost. SUMMARY

[0005] The utility model discloses a multifunctional dust suppression vehicle capable of omnidirectional spraying, aiming at solving the limitations of the prior art, by combining the spray hole adjusting assembly and the vortex ring generating assembly in the fog gun. The spray hole adjusting assembly can flexibly control the spraying mode and range, thereby achieving efficient dust suppression operation at different distances. The vortex ring generating assembly reduces energy consumption and noise level while maintaining or improving dust suppression efficiency. The utility model aims to improve the multifunctionality, effectiveness and environmental friendliness of the dust suppression vehicle in various urban and industrial environments.

[0056] The drawings are only used for illustrative purposes and should not be construed as limiting the patent; in order to better illustrate the embodiment, some components of the drawings may be omitted, enlarged or reduced, and do not represent the actual product size.

[0057] It is understandable to some skilled persons in the art that some known structures and their descriptions in the drawings may be omitted. The technical solutions of the present application will be further described below in combination with the drawings and embodiments.

[0058] Please refer to Figures 1-11 The embodiment provides a multifunctional dust suppression vehicle capable of omnidirectional spraying, which comprises a vehicle body 1, and a double-shaft turntable is arranged between the vehicle body 1 and a fog gun 2. The double-shaft turntable enables the fog gun 2 to adjust the pitch angle and rotate around the vertical direction.

[0059] The fog gun 2 is composed of a first barrel 21, and a vortex ring generating assembly 5 and a nozzle 221 are sequentially arranged in the first barrel 21 along the direction of air flow. The vortex ring generating assembly 5 generates a pulse airflow in the barrel, which can improve the transmission distance of the water mist, thereby reducing the dependence on continuous high-speed airflow to a certain extent, and reducing energy consumption and noise.

[0060] At the front end of the first barrel 21, a nozzle adjusting assembly 3 is arranged. The assembly includes an adjusting ring 32, on which a nozzle is formed, and a gas bag 321 is arranged at the nozzle. By controlling the inflation and deflation of the gas bag 321, the size of the nozzle can be changed. When the gas bag 321 is inflated, it will expand towards the center of the nozzle, reducing its aperture, thereby changing the diffusion shape and distance of the sprayed water mist. For example, reducing the aperture can make the water mist more concentrated and have a longer range, which is suitable for long-distance dust suppression. Conversely, increasing the aperture can make the water mist more dispersed and have a wider coverage, which is suitable for short-distance or large-area dust suppression.

[0061] The adjusting ring 32 is connected to the first barrel 21 through a wind deflector 33, on which a plurality of rotating beams 31 are arranged circumferentially along the first barrel 21. The first ends and the second ends of the rotating beams 31 are respectively detachably hinged to the adjusting ring 32 and the first barrel 21, and are connected through a first driving assembly. By controlling the first driving assembly, the angle of the rotating beams 31 can be changed, thereby adjusting the angle of the wind deflector 33, further realizing the adjustment of the spray direction and range. The wind deflector 33 is made of soft material, for example, the wind deflector 33 can be nylon cloth or plastic.

[0062] The outer side walls of the adjusting ring 32 and the first barrel 21 are respectively provided with a first movable hinge assembly 41 and a second movable hinge assembly 42. These assemblies all include a limiting shoulder 43, a limiting ring 44 and a first push rod 45. By pushing the limiting ring 44 towards or away from the limiting shoulder 43 through the first push rod 45, the unlocking and locking of the two ends of the rotating beam 31 can be realized.

[0063] A second barrel 22 is arranged in the first barrel 21, and the first driving assembly includes a second push rod 34 fixed in the second barrel 22 and an auxiliary rod 341. One end of the auxiliary rod 341 is hinged to the movable end of the second push rod 34, and the other end is hinged to the rotating beam 31. By controlling the extension and retraction of the second push rod 34, the auxiliary rod 341 can be moved, thereby changing the angle of the rotating beam 31 and realizing the adjustment of the shape of the wind deflector 33.

[0064] In order to further realize the control of the spray direction, the nozzle 221 is also connected with a second driving assembly. The assembly includes a third push rod 351, a driving ring 35 drivingly connected with the third push rod 351, and a driving rack 352 arranged on the driving ring 35 and extending axially along the first barrel 21. The nozzle 221 is provided with an adjusting gear 222 meshing with the driving rack 352. By controlling the third push rod 351, the driving ring 35 can be moved along the axial direction of the first barrel 21, thereby driving the driving rack 352 to move, and finally changing the angle of the nozzle 221 through the adjusting gear 222, realizing the adjustment of the spray angle.

[0065] The first flow channel 51 is formed between the first cylinder 21 and the second cylinder 22, and the second flow channel 52 is formed in the second cylinder 22. The flow area of the first flow channel 51 is smaller than that of the second flow channel 52, and the airflow will be further accelerated after passing through the first flow channel 51. The vortex ring generating assembly 5 includes a first wind blocking piece 531, a second wind blocking piece 532, and a third driving assembly. The third driving assembly is used to drive the first wind blocking piece 531 and the second wind blocking piece 532, so that the conduction states of the first flow channel 51 and the second flow channel 52 are opposite, so that vortex rings can be formed in the first flow channel 51 and the second flow channel 52. Further, the first cylinder 21 is also provided with a wind blocking ring 54.

[0066] When the first wind blocking piece 531 and the second wind blocking piece 532 are in the first position, the first wind blocking piece 531 blocks the first flow channel 51, and the airflow only flows out from the second flow channel 52, forming a spray mode. When the first wind blocking piece 531 and the second wind blocking piece 532 are in the second position, the second baffle blocks the second flow channel 52, and the airflow only flows out from the first flow channel 51, forming another spray mode.

[0067] The specific structure of the third driving assembly includes a driving motor 55 fixed in the first cylinder 21, and the output end of the driving motor 55 is connected with a connecting rod 56. One end of the connecting rod 56 is hinged with a transmission rod 57, and the other end of the transmission rod 57 is hinged with the first wind blocking piece 531. The first wind blocking piece 531 can be connected with the second wind blocking piece 532 through the rib plate 533 to realize the alternating blocking or opening of the first flow channel 51 and the second flow channel 52.

[0068] A fan 211 is arranged at the tail end of the first cylinder 21, and a wind deflector 212 for adjusting the output airflow is arranged in front of the fan 211. The fan 211 continuously delivers airflow into the first cylinder 21, and the airflow passes through the wind deflector 212 to eliminate the rotational inertia of the airflow. The driving motor 55 drives the connecting rod 56 to rotate, and under the action of the transmission rod 57, the first wind blocking piece 531 and the second wind blocking piece 532 move forward and backward, periodically block the first flow channel 51 and the second flow channel 52, and the airflow in the first cylinder 21 is sprayed in the form of vortex ring.

[0069] Working principle:

[0070] In the dust suppression operation, the appropriate spray mode and range are selected according to the actual needs. By controlling the inflation of the air bag 321 in the spray hole adjusting assembly 3 and the action of the second push rod 34, the shape, size and length-diameter ratio of the wind deflector 33 can be dynamically adjusted to effectively cover the near and far areas. At the same time, by controlling the position of the wind-blocking piece 53 in the vortex ring generating assembly 5, the airflow channel inside the mist cannon 2 can be changed to form different airflow modes, for example, concentrated and long-range water mist generated through the second flow channel 52, or diffused and wide-range water mist generated through the first flow channel 51. The design of the vortex ring generating assembly 5 aims to utilize the characteristics of vortex flow to improve the pushing efficiency of water mist, thereby reducing energy consumption and noise level while maintaining or improving dust suppression efficiency.

[0071] Based on the above working principle, the present application at least includes the following spray modes:

[0072] 1. Long-distance small-range mode (as shown in the accompanying Figure 7

[0073] The first movable hinge assembly 41 and the second movable hinge assembly 42 at both ends of the rotating beam 31 are in the locked state. The air bag 321 is partially inflated, reducing the diameter of the spray hole of the adjusting ring 32, enhancing the focusing effect of the airflow, improving the spray speed and range, and at this time the output direction of the spray head 221 is parallel to the axis of the first cylinder 21.

[0074] At this time, the vortex ring generating assembly 5 is in working condition, which can reduce the diffusion of water mist in the air by generating vortex flow in the airflow, maintain the integrity of the water mist beam, and significantly improve the spray distance. Vortex flow can also enhance the collision and combination of water mist and dust particles, improving dust suppression efficiency.

[0075] This mode can achieve long-distance precise spraying with a smaller coverage area, which is suitable for precise attack on specific dust points far away, such as high material piles, distant road dust, etc.

[0076] 2. Medium-distance medium-range mode (as shown in the accompanying Figure 8

[0077] This mode is based on the "long-distance small-range mode" and cancels the inflation of the air bag 321, so that the diameter of the spray hole of the adjusting ring 32 is slightly larger than that of the "long-distance small-range mode", and the spray range is correspondingly expanded. At this time, the vortex ring generating assembly 5 is in working condition, and the generation of vortex flow still helps to maintain the stability of the water mist and a certain range, and improves the dust suppression efficiency, and at this time the output direction of the spray head 221 is parallel to the axis of the first cylinder 21.

[0078] ​​In this mode, the spraying can be realized at a medium distance, and the coverage is moderate, which is suitable for dust suppression on medium-distance roads, yards and other areas. Compared with the long-distance mode, the coverage is expanded, but the range is slightly reduced.

[0079] 3. Medium-distance large-range mode (as shown in the accompanying Figure 9

[0080] The first movable hinge assembly 41 is in the unlocked state, and the second movable hinge assembly 42 is in the locked state. The rotating beam 31 is opened to the maximum stroke with the second end 312 as the hinge point, increasing the initial diameter of the front end of the wind deflector 33, so that the sprayed airflow is more dispersed. By moving the first wind-blocking piece 531, the airflow is only discharged from the second flow channel 52, and the airflow will produce a small turbulence when flowing out of the second flow channel 52, so that the water mist begins to diffuse after a certain distance. At this time, the vortex ring generating assembly 5 does not work, and the constraint of the vortex ring is cancelled, so that the water mist is more easily diffused around to form a larger coverage range. At this time, the output direction of the nozzle 221 is parallel to the axis of the first cylinder 21.

[0081] In this mode, the spraying can be realized at a medium distance, and the coverage is larger, which is suitable for dust suppression in a larger area, such as a wider road, an open construction site, etc.

[0082] 4. Small-distance maximum-range mode (as shown in the accompanying Figure 10

[0083] On the basis of the medium-distance large-range mode, the first wind-blocking piece 531 is moved to make the airflow only flow out of the first flow channel 51. The first flow channel 51 is narrower than the second flow channel 52, which can improve the flow rate and dispersion degree of the airflow, and further expand the spraying range. At this time, the vortex ring generating assembly 5 does not work, and the water mist rapidly diffuses in a short distance to form the maximum coverage area.

[0084] In this mode, the spraying can be realized at a short distance with the maximum range, which is suitable for rapid and comprehensive dust suppression in the area around the vehicle, such as water spraying and dust suppression, rapid coverage of the operation area, etc.

[0085] 5. Small-distance omnidirectional range mode (as shown in the accompanying Figure 11

[0086] The first movable hinge assembly 41 is in the locked state, and the second movable hinge assembly 42 is in the unlocked state. The rotating beam 31 is opened to the maximum stroke with the first end 311 as the hinge point, increasing the initial diameter of the rear end of the wind deflector 33, forming a backward spraying outlet, and adjusting the output direction of the nozzle 221 to be perpendicular to the axis of the first cylinder 21. Then, the air bag 321 is fully inflated to completely block the spray holes of the adjusting ring 32. At this time, the axis of the fog gun 2 is perpendicular to the horizontal plane under the adjustment of the double-shaft turntable.​​​

[0087] This mode can achieve near 360-degree or approximately 360-degree omnidirectional spraying, and is suitable for quickly suppressing dust in a closed or semi-closed space around the vehicle, such as a tunnel, a mine tunnel, a garbage disposal station, etc., to form a dust suppression area around the vehicle.

[0088] To further illustrate the specific application scenarios of each mode, the following are some application examples.

[0089] When a belt conveyor far away (e.g. 50 meters away) is found to be generating a large amount of dust, the operator can select the "long-distance small-range mode". At this time, the spray hole of the fog gun 2 is adjusted to the smallest diameter, the vortex ring generating assembly 5 is started, and a high-range, concentrated water mist beam is sprayed to accurately cover the dust generating point and suppress dust diffusion.

[0090] When the dust suppression vehicle is driving on the main road of a mine or construction site and needs to suppress dust on the road along the way, the operator can select the "medium-distance medium-range mode". The spray hole diameter is moderate, the vortex ring generating assembly 5 is working, and a medium-range water mist is sprayed to cover the entire road surface while reducing secondary dust generated by vehicle driving.

[0091] When a large-area material pile at a medium distance (e.g. 20 meters away) needs to be suppressed, the operator can select the "medium-distance large-range mode". The airflow flows out from the second flow channel 52, the vortex ring generating assembly 5 is closed, and a water mist with a wide coverage range is sprayed to quickly reduce the dust on the surface of the entire material pile.

[0092] When the truck has just completed the unloading operation and needs to immediately suppress dust on the ground around the vehicle to prevent residual material from generating dust, the operator can select the "small-distance maximum-range mode". A fan-shaped water mist covering a large area around the vehicle is sprayed to quickly complete the dust suppression operation.

[0093] When the dust suppression vehicle needs to perform dust suppression operations in a narrow tunnel, due to limited space, the dust on the tunnel walls and in the air needs to be suppressed in all directions, the operator can select the "small-distance omnidirectional range mode". The air bag 321 is inflated, the air bag 321 completely blocks the adjusting ring 32, and the auxiliary rod 341 pushes the rotating beam 31 to swing outward with the first end 311 as the hinge point, forming a dense dust suppression mist wall around the vehicle to effectively reduce the dust concentration in the tunnel.

[0094] Obviously, the above embodiments of the present application are merely exemplary but not intended to limit the embodiments of the present application. Based on the above description, any other variations or changes can be made by those skilled in the art without departing from the spirit and principles of the present application. It is not necessary to list all the embodiments here. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present application shall fall within the scope of the claims of the present application.
