Description

Technical Field

[0001] This application relates to the field of fog cannon technology, specifically to an adjustable spray angle fog cannon device for dust suppression vehicles. Background Technology

[0002] As a core piece of equipment for controlling dust pollution, dust suppression vehicles are widely used in dust control operations in various scenarios such as construction sites, mining, road transportation, and ports. Their core working principle is to spray dust suppression liquid atomized by a mist cannon device. The water mist collides, adsorbs, and condenses with dust particles in the air, causing the dust to become heavier and settle, thereby reducing the dust concentration in the air and improving the working environment and air quality.

[0003] For example, the patent with publication number CN220715269U discloses a new type of dust suppression vehicle, including a new type of dust suppression vehicle body, a mounting base and dust suppression components. The angle of the fog cannon body is adjusted by controlling the first hydraulic cylinder so that its spray nozzle is facing upwards. Then, the air inlet is closed and opened by the internal pressure of the six groups of second hydraulic cylinders through the hydraulic pump and the reversing valve via the first row of valves.

[0004] However, the nozzles in the aforementioned patents are fixed nozzles. During operation, the overall angle of the fog cannon body is adjusted by a hydraulic cylinder, but the nozzle position remains fixed. The fog field sprayed by the fixed nozzles is mostly a hollow cone structure. The fog droplets are mainly concentrated in the edge area of ​​the cone fog field, while the fog droplet concentration in the center area of ​​the fog field is low, which easily leads to the phenomenon of central voids, resulting in uneven dust coverage and low dust suppression effect in the dust-generating area.

[0005] Therefore, it is necessary to provide an adjustable spray angle fog cannon device for dust suppression vehicles to solve the above problems.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0027] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0029] like Figure 1-2 As shown, this application provides an adjustable spray angle fog cannon device for a dust suppression vehicle, including a dust suppression vehicle body 1 for supporting the entire fog cannon device. The dust suppression vehicle body 1 is flexible and can move to different work areas according to dust suppression needs, adapting to mobile dust suppression scenarios. A mounting frame 2 is fixedly installed at the rear end of the dust suppression vehicle body 1. The mounting frame 2 provides a stable mounting base for the fog cannon body 3 and the adjustment components 4, ensuring that the fog cannon device does not shake when the vehicle is moving or operating, and ensuring spray accuracy.

[0030] The upper end of the mounting frame 2 is provided with a fog cannon body 3, including a cannon barrel 31 for guiding airflow and water mist; a fan 32 is provided on one side inside the cannon barrel 31. After the fan 32 is started, it can generate a high-speed airflow to provide power for water mist spraying, so that the water mist can spread over a long distance and expand the dust suppression coverage area; an annular pipe 33 is provided on the other side of the cannon barrel 31. Multiple nozzles 34 are provided on the outer wall of the annular pipe 33. The multiple nozzles 34 are evenly distributed around the annular pipe 33, so that the water mist can be sprayed out in a ring evenly, avoiding local water mist concentration or leakage, and improving the uniformity of dust suppression.

[0031] A connecting pipe 35 is provided at the upper end of the annular pipe 33. The connecting pipe 35 is used to connect to the water tank on the dust suppression vehicle body 1. The dust suppression liquid in the water tank is transported to the annular pipe 33 through the connecting pipe 35, and then atomized and sprayed out through the nozzle 34 to form a fine water mist. The water mist combines with the dust particles in the air, causing the dust to increase in weight and settle, thereby achieving the dust suppression effect.

[0032] like Figure 3-4 As shown, the mounting frame 2 is equipped with an adjustment component 4 for adjusting the angle of the fog cannon body 3, which can realize the vertical pitch and horizontal rotation adjustment of the fog cannon to meet the dust suppression needs of different heights and directions. The adjustment component 4 includes a support frame 41 rotatably mounted on the upper end of the mounting frame 2. The support frame 41 provides rotational support for the fog cannon body 3. The fog cannon body 3 is rotatably mounted on the upper end of the support frame 41 and can realize vertical pitch adjustment around the support frame 41.

[0033] An electric push rod 43 is rotatably mounted on one side of the lower end of the support frame 41. The output end of the electric push rod 43 is rotatably connected to the lower end of one side of the cannon barrel 31. The electric push rod 43 serves as the power source for pitch adjustment. Through its extension and retraction, it drives the cannon barrel 31 to rotate around the upper end of the support frame 41. When the electric push rod 43 extends, it pushes the lower end of the cannon barrel 31 forward, increasing the pitch angle of the cannon barrel 31 (raising the spray height). When the electric push rod 43 retracts, it pulls the lower end of the cannon barrel 31 backward, decreasing the pitch angle of the cannon barrel 31 (lowering the spray height). Through the precise extension and retraction of the electric push rod 43, stepless adjustment of the spray angle can be achieved, adapting to dust scenarios of different heights.

[0034] A first drive motor 42 is fixedly installed inside the mounting frame 2. The output end of the first drive motor 42 passes through the mounting frame 2 and is fixedly connected to the lower end of the support frame 41. The first drive motor 42 provides power for horizontal rotation adjustment. When it is necessary to adjust the horizontal spray direction of the fog cannon, the first drive motor 42 is started. The motor output end drives the support frame 41 to rotate around the upper end of the mounting frame 2, thereby driving the fog cannon body 3 to rotate horizontally in sync, achieving 360° horizontal spray coverage without dead angles. This allows for large-scale dust suppression operations without moving the dust suppression vehicle, improving work efficiency.

[0035] like Figure 4-6 As shown, a reciprocating assembly 5 for driving the annular tube 33 to reciprocate is provided on one side of the barrel 31. The reciprocating assembly 5 includes an annular bracket 51 fixedly installed on one side of the barrel 31 by bolts. The annular bracket 51 provides fixed support for the bearing 52. The bearing 52 is fixedly installed on the outer wall of the annular bracket 51. The bearing 52 can reduce the frictional resistance when the gear ring 53 rotates, making the gear ring 53 rotate more smoothly. The gear ring 53 is fixedly installed on the outer wall of the bearing 52. Multiple clips 54 are fixedly installed on the gear ring 53 by bolts. The annular tube 33 is snapped onto the clips 54. The clips 54 firmly connect the annular tube 33 and the gear ring 53, ensuring that the annular tube 33 rotates synchronously when the gear ring 53 rotates. At the same time, the connection of the clips 54 facilitates the disassembly and maintenance of the annular tube 33.

[0036] A drive mechanism for driving the gear ring 53 to rotate is provided on one side of the barrel 31. The drive mechanism includes a mounting plate 55 fixedly installed on the outer wall of one side of the barrel 31. A second drive motor 56 is fixedly installed on one side of the mounting plate 55. The second drive motor 56 serves as the power source for the rotation of the annular tube 33. Its output end passes through the mounting plate 55 and a gear 57 is fixedly installed thereon. The gear 57 meshes with the gear ring 53 to form a gear 57 transmission structure.

[0037] The second drive motor 56 is started, and the output end of the motor drives the gear 57 to rotate. The gear 57 drives the meshing gear ring 53 to rotate around the annular bracket 51, and then drives the annular tube 33 to rotate synchronously through the buckle 54. By controlling the forward and reverse rotation of the second drive motor 56, the reciprocating rotation of the annular tube 33 can be realized, so that the water mist sprayed by the nozzle 34 sweeps back and forth within a certain angle range. Through the reciprocating rotation of the annular tube 33, the water mist sprayed by the nozzle 34 fills the central area of ​​the fog field and improves the uniformity of the water mist coverage.

[0038] A first protective cover 6 is fixedly installed on one side of the mounting plate 55. The first protective cover 6 completely covers the second drive motor 56, which can isolate dust, water vapor, gravel and other impurities in the working environment, prevent impurities from entering the motor and causing short circuits and wear, extend the service life of the motor and ensure the stable operation of the drive mechanism. A second protective cover 7 is fixedly installed on the other side of the mounting plate 55. The second protective cover 7 covers the meshing area of ​​the gear 57 and the gear ring 53, prevents the meshing part from being blocked by dust or impacted by foreign objects, prevents the gear 57 from jamming, and ensures the smooth reciprocating rotation of the annular tube 33.

[0039] A counterweight 8 is fixedly installed on the outer wall of the other side of the cannon barrel 31. The counterweight 8 balances the weight on both sides of the cannon barrel 31, preventing the fog cannon from tilting or swaying due to the shift of the center of gravity when adjusting the angle. When the electric push rod 43 drives the cannon barrel 31 to pitch, the counterweight 8 can counteract the gravity on one side of the cannon barrel 31, keeping the cannon barrel 31 balanced and ensuring accurate adjustment of the spray angle. At the same time, it reduces the stress on the support frame 41 and the electric push rod 43, extends the service life of the adjustment component 4, and ensures the stability of the entire device during operation.

[0040] Working principle: When this device is working, the water supply system on the dust suppression vehicle body 1 is first started. The dust suppression liquid is transported to the annular pipe 33 through the connecting pipe 35 and then atomized and sprayed out through multiple nozzles 34. At the same time, the fan 32 in the cannon barrel 31 is started, generating a high-speed airflow that sprays the atomized water mist forward, forming a large-scale dust suppression fog field.

[0041] When it is necessary to adjust the spray angle of the fog cannon, it can be achieved through the adjustment component 4. Activate the electric push rod 43, and its telescopic movement will cause the cannon barrel 31 to pitch around the rotation point at the upper end of the support frame 41, thereby changing the vertical spray angle of the fog cannon to adapt to dust sources at different heights. Activate the first drive motor 42 to drive the support frame 41 and the fog cannon body 3 to rotate horizontally as a whole, achieving 360° coverage without blind spots and improving operational flexibility.

[0042] The second drive motor 56 in the reciprocating assembly 5 is activated, driving the gear 57 to rotate. This drives the gear ring 53 to reciprocate under the support of the bearing 52, which in turn drives the annular tube 33 and the nozzle 34 to oscillate within a certain angle range via the latch 54. The reciprocating motion of the nozzle 34 causes the water mist to dynamically fill the central area of ​​the fog field, effectively filling the central voids and improving the uniformity of dust suppression coverage.

[0043] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
