Description

Technical Field

[0001] The present invention belongs to the field of dust suppression vehicles, and particularly relates to a multi-functional dust suppression vehicle capable of spraying in all directions. Background Art

[0002] In the fields of environmental governance and urban cleaning, dust suppression vehicles, as an important piece of equipment, are widely used in places such as roads and construction sites to reduce dust particles in the air by spraying water mist and improve air quality. Most of the dust suppression vehicles on the market at present are equipped with spraying devices, such as fog cannons. Their main function is to atomize water and spray it into the air, where it combines with dust to make it settle.

[0003] However, there are some obvious deficiencies in the spraying devices of existing dust suppression vehicles. First of all, the current spraying systems usually cannot flexibly adjust the spraying range. This means that the sprayer can only effectively cover an area at a certain distance from it, that is, the far end of the spray range, while the area close to the sprayer often has poor effects 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 operate on a narrow road or needs to spray closely on a specific dust generating point (such as a material stacking place), the existing fixed spraying mode is inadequate. Either it cannot accurately cover the target area, or local water accumulation is caused due to the over-concentration of water mist, which instead affects the operation effect. Even more, when dust suppression operations need to be carried out on targets at different distances, the operator often has to barely adapt by adjusting the vehicle's driving speed and distance. This method is inefficient and difficult to ensure the spraying effect.

[0004] Secondly, most of the current mainstream fog cannon technologies use axial flow fans as the air supply mechanism. The axial flow fan accelerates the air flow through the rotating blades, generates high-speed air flow, and pushes the atomized water droplets out. The magnitude of the wind speed directly determines the spraying distance of the water mist. In order to increase the spraying distance, the existing technology mainly relies on increasing the rotational speed of the fan or increasing the installation angle of the blades. Increasing the rotational speed means that the fan motor needs to consume more electrical energy to overcome air resistance, resulting in a significant increase in energy consumption. At the same time, the high-speed rotating blades will generate strong aerodynamic noise when rubbing against the air. Especially when the rotational speed is high, the noise problem will be more prominent, seriously affecting the tranquility of the surrounding environment and even possibly damaging the hearing of the operator. Increasing the blade installation angle will also increase the interaction force between the fan blades and the air. Although it can also increase the wind speed to a certain extent, it will also cause an increase in the motor load, energy consumption, and will also be accompanied by noise generation. In some occasions with high environmental protection requirements, such as near the city center, schools, and hospitals, the use of dust suppression vehicles with high energy consumption and high noise will be strictly restricted. In addition, frequently operating the fan at high power will shorten the service life of the equipment and increase the maintenance cost. Summary of the Invention

[0056] The accompanying drawings are only for illustrative purposes and should not be construed as a limitation of this patent; for better illustration of this embodiment, some components in the drawings may be omitted, enlarged or reduced, which does not represent the dimensions of the actual product.

[0057] For those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted. The technical solutions of the present invention will be further described below with reference to the drawings and embodiments.

[0058] Please refer to Figures 1-11 , this embodiment provides a multifunctional dust suppression vehicle capable of spraying in all directions, including a vehicle body 1. A double-axis turntable is provided between the vehicle body 1 and the fog cannon 2. The double-axis turntable enables the fog cannon 2 to adjust both the pitching angle and rotate around the vertical direction.

[0059] The fog cannon 2 is composed of a first cylinder body 21. Inside the first cylinder body 21, a vortex ring generating assembly 5 and a nozzle 221 are sequentially arranged along the direction of air flow. The function of the vortex ring generating assembly 5 is to generate pulsed air flow inside the cylinder body. This pulsed air flow can increase the transmission distance of the water mist, thereby reducing the dependence on continuous high-speed air flow to a certain extent, reducing energy consumption and noise.

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

[0061] The adjusting ring 32 and the first cylinder body 21 are connected by an air guide cover 33, and a plurality of rotating beams 31 distributed along the circumferential direction of the first cylinder body 21 are arranged on the air guide cover 33. The first end and the second end of these rotating beams 31 are respectively detachably hinged to the adjusting ring 32 and the first cylinder body 21, and are connected by a first driving assembly. By controlling the first driving assembly, the angle of the rotating beam 31 can be changed, thereby adjusting the angle of the air guide cover 33 and further realizing the adjustment of the spray direction and range. The air guide cover 33 is made of a soft material. For example, the air guide cover 33 can be nylon cloth or plastic.

[0062] A first movable hinge assembly 41 and a second movable hinge assembly 42 are respectively arranged on the outer side walls of the adjusting ring 32 and the first cylinder body 21. These assemblies both include a limit shoulder 43, a limit ring 44, and a first push rod 45. By pushing the limit ring 44 close to or away from the limit shoulder 43 with the first push rod 45, the unlocking and locking of both ends of the rotating beam 31 can be realized.

[0063] A second cylinder body 22 is arranged inside the first cylinder body 21. The first driving assembly includes a second push rod 34 fixed inside the second cylinder body 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 telescopic movement of the second push rod 34, the auxiliary rod 341 can be driven to move, thereby changing the angle of the rotating beam 31 and realizing the adjustment of the shape of the air guide cover 33.

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

[0065] A first flow channel 51 is formed between a first cylinder body 21 and a second cylinder body 22, and a second flow channel 52 is formed inside the second cylinder body 22. The flow-through area of the first flow channel 51 is smaller than that of the second flow channel 52, and the air flow will be further accelerated after passing through the first flow channel 51. The vortex ring generating assembly 5 includes a first wind blocking member 531, a second wind blocking member 532 and a third driving assembly. The third driving assembly is used to drive the first wind blocking member 531 and the second wind blocking member 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 both the first flow channel 51 and the second flow channel 52. Further, a wind blocking ring 54 is also arranged inside the first cylinder body 21.

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

[0067] The specific structure of the third driving assembly includes a driving motor 55 fixed inside the first cylinder body 21. The output end of the driving motor 55 is connected with a connecting rod 56. One end of the connecting rod 56 is hinged to one end of a transmission rod 57, and the other end of the transmission rod 57 is hinged to the first wind blocking member 531. The first wind blocking member 531 can be connected to the second wind blocking member 532 through a rib plate 533 to alternately block or open 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 body 21, and a wind guiding plate 212 for adjusting its output air flow is arranged in front of the fan 211. The fan 211 continuously conveys air flow into the first cylinder body 21. The air flow passes through the wind guiding plate 212 to eliminate the rotational inertia of the air flow. The driving motor 55 drives the connecting rod 56 to rotate. Under the action of the transmission rod 57, the first wind blocking member 531 and the second wind blocking member 532 move back and forth, periodically blocking the first flow channel 51 and the second flow channel 52, and spraying the air flow in the first cylinder body 21 in the form of vortex rings.

[0069] Working principle:

[0070] When carrying out dust suppression operations, select an appropriate spray mode and range according to actual requirements. By controlling the inflation of the airbag 321 and the movement of the second push rod 34 in the spray hole adjustment assembly 3, the shape, size, and aspect ratio of the air guide cover 33 can be dynamically adjusted to achieve effective coverage of both short-distance and long-distance areas. At the same time, by controlling the position of the wind shield 53 in the vortex ring generating assembly 5, the air flow channel inside the fog cannon 2 can be changed to form different air flow patterns. For example, concentrated and long-range water mist can be generated through the second flow channel 52, or diffused and wide-coverage water mist can be generated through the first flow channel 51. The design of the vortex ring generating assembly 5 aims to utilize the characteristics of the vortex to improve the pushing efficiency of the water mist, thereby reducing energy consumption and noise levels while maintaining or improving the dust suppression efficiency.

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

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

[0073] Both the first movable hinge assembly 41 and the second movable hinge assembly 42 at both ends of the rotating beam 31 are in a locked state. The airbag 321 is partially inflated, reducing the diameter of the spray holes of the adjustment ring 32, enhancing the focusing effect of the air flow, increasing the spraying speed and range. At this time, the output direction of the nozzle 221 is parallel to the axis of the first cylinder 21.

[0074] At this time, the vortex ring generating assembly 5 is in a working state. By generating vortices in the air flow, it can reduce the diffusion of the water mist in the air, maintain the integrity of the water mist beam, and thus significantly increase the spraying distance. The vortex can also enhance the collision and combination of the water mist and dust particles, improving the dust suppression efficiency.

[0075] This mode can achieve precise long-distance spraying with a small coverage area, and is suitable for precisely targeting specific dust generation points in the distance, such as material piles at high places, road dust in the distance, etc.

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

[0077] In this mode, based on the "long-distance and small-range mode", the inflation of the airbag 321 is cancelled, making the diameter of the spray holes of the adjustment ring 32 slightly larger than that in the "long-distance and small-range mode", and the spraying range is correspondingly expanded. At this time, the vortex ring generating assembly 5 is in a working state. The generation of vortices still helps to maintain the stability of the water mist and a certain range, and improves the dust suppression efficiency. At this time, the output direction of the nozzle 221 is parallel to the axis of the first cylinder 21.

[0078] In this mode, medium-distance spraying can be achieved, with a moderate coverage range, suitable for dust suppression operations in areas such as roads and yards at medium distances. Compared with the long-distance mode, the coverage range is slightly expanded, but the spraying range is slightly reduced.

[0079] 3. Medium-distance large-range mode (as shown in the appendix 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 air deflector 33, making the ejected air flow more dispersed. By moving the first wind shield 531, the air flow only flows out from the second flow channel 52. When the air flow flows out from the second flow channel 52, less turbulence will be generated, so that the water mist will start to disperse after a certain distance. At this time, the vortex ring generating assembly 5 does not work, canceling the constraint of the vortex ring, and the water mist is more likely to disperse around, forming 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, medium-distance spraying can be achieved, with a large coverage range, suitable for dust suppression of larger areas, such as wider roads, open construction sites, etc.

[0082] 4. Short-distance maximum-range mode (as shown in the appendix Figure 10 )

[0083] Based on the "medium-distance large-range mode", in this mode, by moving the first wind shield 531, the air flow only flows out from the first flow channel 51: the first flow channel 51 is narrower than the second flow channel 52, which can increase the flow velocity and dispersion degree of the air flow, further expanding the spraying range. At this time, the vortex ring generating assembly 5 does not work, and the water mist spreads rapidly within a short distance, forming the largest coverage area.

[0084] In this mode, maximum-range spraying at a short distance can be achieved, suitable for quickly and comprehensively suppressing dust in the area around the vehicle, such as sprinkling dust suppression and quickly covering the operation area.

[0085] 5. Short-distance omnidirectional range mode (as shown in the appendix 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 rotating shaft of the first end 311 as the hinge point, increasing the initial diameter of the rear end of the air deflector 33, forming an outlet for backward spraying. At the same time, the output direction of the nozzle 221 is adjusted to be perpendicular to the axis of the first cylinder 21; then the airbag 321 is fully inflated, so that the airbag 321 completely blocks the spray holes of the adjusting ring 32; at this time, the axis of the fog cannon 2 is perpendicular to the horizontal plane under the adjustment of the two-axis turntable.

[0087] This mode can achieve 360-degree or nearly 360-degree all-round spraying at close range, and is suitable for quickly suppressing dust in enclosed or semi-enclosed spaces around vehicles, such as tunnels, mine roadways, waste treatment stations, etc., and can form a dust suppression area surrounding the vehicle.

[0088] To further illustrate the specific application scenarios of the above various modes, the following are some application embodiments.

[0089] When it is found that a belt conveyor in the distance (e.g., 50 meters away) is generating a large amount of dust, the operator can select the "long-distance small-range mode". At this time, the spray holes of the fog cannon 2 will be adjusted to the minimum diameter, and the vortex ring generating assembly 5 is activated to eject a high-range and concentrated water mist beam, which precisely covers the dust generation point to inhibit dust diffusion.

[0090] When the dust suppression vehicle is driving on the main roads in the mining area or construction site and needs to suppress dust on the roads along the way, the operator can select the "medium-distance medium-range mode". The spray hole diameter is moderate, and the vortex ring generating assembly 5 works to eject a water mist with a medium distance and medium range, covering the entire road surface and reducing secondary dust generated by vehicle driving at the same time.

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

[0092] When the truck has just completed the unloading operation and it is necessary to immediately suppress dust on the ground around the vehicle to prevent dust from being generated by the remaining materials, the operator can select the "short-distance maximum-range mode". A fan-shaped water mist covering a large area around the vehicle is ejected to quickly complete the dust suppression operation.

[0093] When the dust suppression vehicle needs to carry out dust suppression operations in a narrow tunnel, due to limited space, it is necessary to comprehensively suppress the dust on the inner wall and in the air of the tunnel. The operator can select the "short-distance omnidirectional range mode". The airbag 321 is inflated, the airbag 321 completely blocks the adjusting ring 32, and the auxiliary rod 341 pushes the rotating beam 31 to swing outwards with the first end 311 as the hinge point, forming a dense dust suppression fog wall around the vehicle and effectively reducing the dust concentration in the tunnel.

[0094] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or alterations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the claims of the present invention.
