Description

Technical Field

[0001] This invention belongs to the technical field of fog cannon equipment, specifically relating to a fog cannon device that enhances spray. Background Technology

[0002] With increasing public awareness of environmental protection, dust generated during construction has become a major concern in the construction industry, posing a threat to air quality and construction workers, especially in urban areas or densely populated locations. To address this dust problem, mist cannons are commonly used to spray water mist. This water mist absorbs and encapsulates airborne dust particles, effectively reducing the concentration of particulate matter and mitigating smog. Currently, conventional mist cannons have a relatively basic structure, consisting of a base and a rotatable cannon barrel. The base houses a motor and water tank for power and water supply. The barrel is supported by a rotatable bracket and can rotate vertically to spray water mist upwards. A ring of nozzles surrounds the barrel, and a fan is located at the bottom. Sometimes, the base is a vehicle. However, conventional mist cannons have limited vertical rotation angles for spraying. For dust suppression at higher locations, the entire mist cannon needs to be transported to a higher position before spraying. Moreover, the single-ring nozzles at the nozzle opening are arranged around the circumference of the nozzle opening, forming a single ring of water mist, which does not have sufficient contact with airborne particles, and the dust suppression effect needs to be improved. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides a fog cannon device for enhanced spraying, comprising, from bottom to top, a base, a support frame, and a spray cylinder. The base contains a power supply, a motor, and a water tank.

Detailed Implementation

[0026] This embodiment provides a fog cannon device for enhancing spray, such as... Figures 1-5 As shown, from bottom to top, it includes a base 1, a support frame 2, and a spray cylinder 3. The base 1 is equipped with a power supply, a motor, and a water tank. The support rod 4 at the bottom of the support frame 2 is rotatably connected to the base 1, and the spray cylinder 3 is rotatably connected to the upper part of the support frame 2, so that the support rod 4 drives the spray cylinder 3 to rotate in the horizontal direction through the support frame 2, and the spray cylinder 3 can also rotate in the vertical direction.

[0027] One end of the spray cylinder 3 is the cylinder opening 8, and the other end is the cylinder bottom. The cylinder bottom is equipped with a fan 9, the cylinder opening 8 is equipped with a first spray section 10, the spray cylinder 3 is equipped with a wind accelerator, and the wind accelerator is equipped with a second spray section 11. The fan 9 and the wind accelerator provide spray power, and both the first spray section 10 and the second spray section 11 can spray water mist to the outside of the spray cylinder 3.

[0028] Optionally, the support frame 2 includes a vertical support rod 4 and a U-shaped bracket. The bottom of the support rod 4 is rotatably connected to the through groove on the upper surface of the base 1. The support rod 4 is hollow and open at both the top and bottom. The wires and water pipes inside the base 1 pass through the support rod 4 and out of the base 1, and then connect to the spray cylinder 3.

[0029] The support includes a horizontal beam 5 and vertical support rods 6 at both ends of the beam 5. The top of the support rod 4 is fixedly connected to the middle of the beam 5. The beam 5 has through holes corresponding to the positions of the support rods 4, so that the internal space of the support rods 4 can be connected to the outside. The top of a support rod 6 is rotatably connected to both sides of the spray cylinder 3, so that the spray cylinder 3 swings up and down with the tops of the two support rods 6 as fulcrums.

[0030] Optionally, the spray cylinder 3 is provided with a through hole at the position corresponding to the support rod 4, so that the pipeline passing through the support rod 4 enters the spray cylinder 3 through the through hole and then connects to the fan and the first spray section inside the spray cylinder 3.

[0031] The power supply, motor and water tank in the base 1 of this invention are the same as those in the prior art. The difference is that the base 1 of a traditional fog cannon has several through holes on its upper surface, which are used to pass through wires and water pipes respectively. The cannon barrel also has several through holes for connecting wires and water pipes. The arrangement of the pipes is irregular and messy, which causes the cannon barrel to be hindered by the pipes when it rotates left, right and up and down, and the pipes need to be tidied up at any time.

[0032] This invention utilizes the internal space of a vertically positioned support rod 4 as a confinement tube for pipelines. All pipelines pass through the support rod 4 and exit the base 1. Rotation of the support rod 4 does not affect the internal pipelines. The pipelines extend into the spray cylinder 3 through corresponding through holes. When the spray cylinder 3 rotates horizontally about the support rod 4, or swings up and down about the top of the support rod 6, it is unaffected by the pipelines within the through holes. This eliminates the need for constant pipeline adjustments, improving operational convenience and safety.

[0033] Optionally, the spray tube 3 is cylindrical, and the diameter of the tube opening 8 is not greater than the diameter of the tube bottom. It can be a tube from an existing fog cannon, and the straight line connecting the center of the tube bottom and the center of the tube opening 8 is the central axis of the spray tube 3.

[0034] Optionally, the blower 9 at the bottom of the spray cylinder 3 includes a drive motor 12 and several blades. The bottom of the cylinder is provided with a hollow protective railing. Blades are provided between the drive motor 12 and the protective railing. The drive motor 12 can be fixed inside the spray cylinder 3 by several connecting rods. Wires are inserted through the through hole to connect to the drive motor 12. When the blower 9 rotates, it draws air from outside the bottom of the cylinder into the spray cylinder 3 through the protective railing and then sprays it outward from the cylinder opening 8.

[0035] Optionally, the wind accelerator includes a rotating shaft 13 and a first rotating part 14 and a second rotating part 15 connected to the rotating shaft 13. The rotating shaft 13 coincides with the central axis of the spray tube 3. The drive motor 12 is a dual-axis motor with two rotating shafts, one connected to the blades and the other connected to the rotating shaft 13, which can drive the fan 9 and the wind accelerator to rotate simultaneously.

[0036] A second spray section 11 is provided between the first rotating part 14 and the second rotating part 15. The first spray section 10 is detachably connected to the second spray section 11 through a connecting water pipe 16 to fix the position of the second spray section 11.

[0037] Further optionally, the first rotating part 14 is cylindrical in shape. The end of the first rotating part 14 closest to the second spray part 11 is the front end, and the other end is the rear end. The diameter of the front end is not less than the diameter of the second spray part 11, the diameter of the rear end is greater than the diameter of the front end, and the diameter of the rear end is slightly smaller than the diameter of the corresponding spray tube 3 part, so as not to affect the rotation of the first rotating part 14.

[0038] The first rotating part 14 includes several arc-shaped first rotating blades 17. The several first rotating blades are evenly distributed along the circumference of the first rotating part 14. The first rotating blades are arc-shaped in the length direction and protrude towards the inner wall of the spray tube 3. The first rotating blades are inclined relative to the tangent direction of the surface of the first rotating part 14 on which they are located. Adjacent first rotating blades do not contact each other and have gaps.

[0039] In one specific implementation, in every three adjacent first rotating blades, the left side of the middle first rotating blade covers the right side of the left first rotating blade, and the left side of the right first rotating blade covers the right side of the middle first rotating blade.

[0040] Alternatively, the second rotating part 15 is cylindrical in shape, with one end of the second rotating part 15 near the cylinder opening 8 as the front end and the other end as the rear end. The diameter of the front end is not greater than the diameter of the cylinder opening 8, and the diameter of the rear end is not less than the diameter of the second spray part 11.

[0041] The second rotating part 15 includes a plurality of arc-shaped second rotating blades 18, which are evenly distributed along the circumference of the second rotating part 15. The second rotating blades 18 are arc-shaped along their length and protrude toward the inner wall of the spray cylinder 3. The second rotating blades 18 are inclined relative to the tangent direction of the surface of the second rotating part 15 on which they are located, and adjacent second rotating blades do not contact each other and have gaps. The first rotating part 14 and the second rotating part 15 are concentrically arranged with the spray cylinder 3.

[0042] In one specific implementation, in every three adjacent second rotating blades, the left side of the middle second rotating blade covers the right side of the left second rotating blade, and the left side of the right second rotating blade covers the right side of the middle second rotating blade.

[0043] Both the first and second rotating blades are connected to the rotating shaft via one or more connecting rods.

[0044] Optionally, both the first spray section 10 and the second spray section 11 are annular. The diameter of the first spray section 10 is larger than the diameter of the second spray section 11, and the diameter of the first spray section 10 is slightly smaller than the diameter of the nozzle 8, so that the first spray section 10 can be installed on the inner wall of the nozzle 8.

[0045] The first spray section 10 has several first nozzles on its side facing the outer side of the nozzle 8, and the several first nozzles are evenly arranged in a circle around the circumference of the first spray section 10; the second spray section 11 has several second nozzles on its side facing the nozzle 8, and the several second nozzles are evenly arranged in a circle around the circumference of the second spray section 11; the first spray section 10 and the second spray section 11 are concentrically arranged with the spray cylinder 3.

[0046] Further optional, at least two connecting water pipes 16 are evenly arranged on the side of the first spray section 10 facing the inside of the spray cylinder 3. The two ends of the connecting water pipes 16 are respectively connected to the first spray section 10 and the second spray section 11. The connecting water pipes 16 are rigid pipes that can support and fix the position of the second spray section 11 inside the wind accelerator.

[0047] A water pipe that enters through the through hole of the spray cylinder 3 extends close to the inner wall of the spray cylinder 3 toward the cylinder opening 8 and connects to the first spray section 10 to supply water to the first spray section 10. The first spray section 10 supplies water to the second spray section 11 through the connecting water pipe 16.

[0048] Traditional fog cannons use a fan 9 at the bottom of the cannon to provide airflow to a ring of nozzles at the cannon opening 8, propelling water mist outwards along the length of the spray cannon 3. The single ring of water mist formed by the nozzles at the cannon opening 8 contains a small amount of water droplets, resulting in insufficient contact with airborne particles. To achieve the same dust suppression effect, a longer spraying time is required.

[0049] Based on the first spray section 10 at the nozzle 8, this invention adds a second spray section 11 inside the spray cylinder 3. The diameter of the second spray section 11 is smaller than that of the first spray section 10, achieving multi-ring spraying and increasing the spray volume. This invention also incorporates a wind accelerator inside the spray cylinder 3, which provides secondary acceleration to the airflow within the spray cylinder 3 and agitates the airflow, working in conjunction with the second spray section 11 to achieve multi-dimensional spraying. Specifically, the first rotating section 14 is thin at the front and thick at the rear. The fan 9 provides the initial aerodynamic force to the first rotating section 14, with most of the airflow entering the rear end of the first rotating section 14 and flowing along its length. Simultaneously, under the agitation of the first rotating blade 17, the airflow within the first rotating section 14 flows in a spiral forward motion. As the inner diameter of the first rotating section 14 decreases, the airflow gradually accelerates, reaching its maximum velocity when it reaches the second spray section 11. This velocity carries the water mist sprayed from the second spray section 11, continuing to flow along the second rotating section 15, while also preventing the water mist sprayed from the second spray section 11 from falling into the first rotating section 14. The second rotating section 15 is wider at the front and narrower at the rear. Although the increased diameter of the flow channel causes a slight decrease in air velocity after the water mist-containing airflow enters the second rotating section 15, the airflow still gains propulsive power for spiral forward movement under the stirring action of the second rotating blade 18. Therefore, the impact of the reduced air velocity is within an acceptable range, resulting in very few droplets falling into the first rotating section 14. In addition, the rotational stirring action of the second rotating section 15 allows the airflow and water mist to fully contact and mix, ensuring that the water mist is evenly distributed across the cross-section of the spray nozzle 3. As a result, when the water mist exits the nozzle 8, it merges with the water mist sprayed from the first spray section 10, forming a larger area and richer water mist coverage, thus improving the dust suppression effect.

[0050] Due to the arrangement of the first rotating blade 17 and the second rotating blade 18, some airflow will flow back and forth inside and outside the wind accelerator, sometimes entering the wind accelerator and sometimes flowing out of the wind accelerator. This does not forcibly restrict the airflow, so as to avoid reducing the airflow and causing airflow obstruction. Since the airflow spirals forward, with both inflow and outflow, the wind accelerator can generally stir and accelerate the airflow.

[0051] Further optionally, the width of the same first rotating blade 17 gradually decreases along the direction from the bottom of the cylinder to the opening 8, and the width of the same second rotating blade 18 gradually decreases along the direction from the opening 8 to the bottom of the cylinder; the number of first rotating blades 17 and second rotating blades 18 is the same and they correspond one to one, and the front end of the first rotating blade 17 is connected to the rear end of the second rotating blade 18.

[0052] The second rotating blade 18 is preferably made of plastic, which is waterproof and prevents rusting. The first rotating blade 17 and the second rotating blade 18 are detachable.

[0053] Optionally, the nozzle 8 is provided with a retractable spray mechanism, which includes a front edge ring 19, a telescopic folding cylinder 20, and a storage groove 7. The first spraying part 10 is provided on the inner side wall of the front end of the front edge ring 19. The front edge ring 19 is connected to the front end of the telescopic folding cylinder 20. The rear end of the telescopic folding cylinder 20 is connected to the inside of the storage groove 7. The storage groove 7 is provided on the inner wall of the nozzle 8 and is used to accommodate the telescopic folding cylinder 20 after it has been retracted and folded.

[0054] Optionally, the diameter of the front end of the front edge ring 19 is larger than the diameter of the rear end, and the diameter of the front edge ring 19 varies uniformly. The outer wall of the middle part of the front edge ring 19 is connected to the front end of the telescopic folding cylinder 20. The outer side of the storage groove 7 is connected to the inner wall of the cylinder opening 8, and the inner side faces the rear part of the front edge ring 19. The outer side of the front part of the front edge ring 19 contacts the edge of the cylinder opening 8, and the rear part of the front edge ring 19 is inserted into the inner ring of the storage groove 7, but does not enter the interior of the storage groove 7, so as to support the front edge ring 19.

[0055] Optionally, an operating rod is provided on each of the two outer sides of the spray cylinder 3. The top end of the operating rod is connected to the outer side of the front edge ring 19 of the cylinder, and the bottom end extends to the bottom of the cylinder. Several through holes are provided in the middle of the operating rod, and the several through holes are arranged along the length direction of the operating rod. The outer side of the top end of the support rod 6 is also provided with a through hole, which is used to correspond to a certain through hole of the operating rod to temporarily support the operating rod.

[0056] This invention addresses the problem of the inability to adjust the nozzle 8 of existing fog cannons by proposing a retractable spray mechanism and operating levers. Each operating lever corresponds one-to-one with a support rod 6. Manual operation brings the two operating levers parallel, thereby shifting the leading edge ring 19 of the spray cannon. For example, pushing the two operating levers forward, upward, or along the length of the spray cannon 3 causes the leading edge ring 19 to extend beyond the spray cannon 3. The front end of the telescopic folding tube 20 moves with the leading edge ring 19, and a portion of the telescopic folding tube 20 extends out of the receiving groove 7, effectively lengthening the front end of the spray cannon 3 and changing the spray angle at the front end. Once the leading edge ring 19 is in position, the operating levers align with the corresponding through holes on the support rods 6, and a pin is inserted through the two corresponding through holes to fix the position of the operating levers.
