Description

A mobile dust suppression fog cannon vehicle Technical Field

[0001] This utility model relates to the field of fog cannon vehicles, and more specifically, it relates to a fog cannon vehicle used for dust suppression. Background Technology

[0002] The official name of the fog cannon truck is a multi-functional dust suppression truck. It is a device specifically designed to control dust. Its working principle is to atomize water into tiny water droplets of 10 to 150 micrometers in size through a high-pressure atomization system, and then spray these water droplets to a distance through the principle of wind delivery to form a large area of ​​water mist layer, thereby achieving the effects of dust reduction, dryness reduction, road wetting and road washing. It can reduce dust, cool down and purify the air in the environment after operation.

[0003] For example, Chinese Patent Publication CN114250736A discloses a fog cannon vehicle, which includes a vehicle body, a water tank, and a fog cannon. A carrier plate is mounted on the vehicle body, the water tank is mounted on the carrier plate, a first plate is mounted on the carrier plate that slides along the height direction, a first drive mechanism is mounted on the carrier plate to adjust the first plate up and down, a second plate is mounted on the first plate that adjusts along the horizontal direction, a second drive mechanism is mounted on the first plate to adjust the second plate along the horizontal direction, a first turntable is rotatably mounted on the second plate, the rotation axis of the first turntable is set along the height direction, a first rotation mechanism is mounted on the first turntable to drive the first turntable to rotate, and the fog cannon is mounted on the first turntable. This application has the effect of increasing the spray range, thereby improving usability.

[0004] The spray mechanism in the above technical solution is a traditional annular tube. The diameter of the traditional annular tube is fixed, which directly limits the coverage area of ​​the spray. The fixed diameter of the annular tube means that the spray concentration is not adjustable. In actual work, it is difficult to meet different spray requirements. Different environments and cleaning needs require different spray volumes. The fixed diameter of the annular tube cannot meet diverse needs and cannot be adjusted according to different operational requirements, resulting in insufficient flexibility.

[0005] Therefore, a new solution is needed to address this problem. Summary of the Invention

[0006] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a mobile dust suppression fog cannon vehicle that uses an arc-shaped protective shell and telescopic protective strips to block foreign objects that are splashed to both sides when the cleaning brush sweeps the road surface, thus preventing hard foreign objects from splashing onto pedestrians or vehicles passing by the cleaning vehicle and causing them injury, thereby improving the safety of cleaning operations.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a mobile dust suppression fog cannon vehicle, comprising: a mobile vehicle, an installation platform mounted on the top of the mobile vehicle, a spray cylinder mounted on the top of the installation platform, and fan blades installed inside the spray cylinder;

[0008] A spray assembly is disposed inside a spray cylinder. The spray assembly includes a mounting frame fixed inside the spray cylinder. One end of the mounting frame is fixed with multiple hollow strips. Multiple slots are opened inside the mounting frame. An expansion member is disposed outside the mounting frame. An annular tube is mounted on the expansion member. The annular tube includes multiple rigid pipes. A telescopic tube connects two adjacent rigid pipes. Atomizing nozzles are disposed outside each of the multiple rigid pipes.

[0009] By adopting the above technical solution, during spraying, the rigid pipe can be expanded outward according to the expansion and contraction parts. When the rigid pipe expands outward, the telescopic tube will extend, maintaining the overall closure of the annular pipe, thereby increasing the overall diameter and circumference of the annular pipe. Conversely, when the expansion and contraction parts retract, the rigid pipe will be pulled inward. When the rigid pipe retracts inward, the telescopic tube will fold back, thereby decreasing the overall diameter and circumference of the annular pipe.

[0010] The present invention is further configured such that: the expanding member includes a movable seat that slides inside the mounting frame, an electric push rod that is fixed outside the mounting frame, and lifting bars that slide inside multiple hollow bars respectively. One end of each of the lifting bars is fixed outside the multiple rigid pipes. Expanding bars rotatably connect the multiple lifting bars and the movable seat. One end of the electric push rod is fixed outside the movable seat.

[0011] The present invention is further configured such that: the atomizing nozzle includes a flexible tube fixed to the outside of a rigid pipe, and an atomizing nozzle is fixed to one end of the flexible tube.

[0012] The present invention is further configured such that: the spray assembly also includes a deflector disposed outside the rigid pipe, the deflector being used to change the spray angle of the atomizing nozzle.

[0013] The present invention is further configured such that: the inside of the spray cylinder is provided with multiple through slots; the deflecting component includes an annular strip that slides outside the spray cylinder, multiple hydraulic cylinders that are fixed outside the spray cylinder, connecting sleeves that rotate outside multiple rigid pipes respectively, and two hollow limiting strips that are fixed to one end of the lifting strip respectively; and multiple hoses are respectively fixed inside the multiple connecting sleeves.

[0014] One end of each of the multiple hydraulic cylinder telescopic rods is fixed to the outside of the annular bar. Multiple connecting rods are passed through the inside of the annular bar. The multiple connecting rods are respectively passed through the inside of multiple through slots. One end of each of the multiple connecting rods is fixed with a drive rod. One end of the drive rod slides inside the inside of two hollow limiting strips through two short shafts. Two hollow rods are fixed below each of the multiple connecting sleeves. The other end of the drive rod slides inside the two hollow rods through two connecting shafts.

[0015] The present invention is further configured such that: a water tank is fixed above the mobile vehicle, and the water tank is connected to one of the rigid pipes through a water conveying mechanism.

[0016] In summary, this utility model has the following beneficial effects:

[0017] 1. The moving seat is pushed by an electric push rod, which causes the expansion and contraction strips to gradually expand or contract outside the mounting frame. When expanding, the lifting strip moves in the hollow strip to increase the total length of both, thereby increasing the diameter of the annular tube. When contracting, the diameter of the annular tube is reduced. The spray concentration can be adjusted according to different environments and cleaning needs to meet diverse requirements and provide high flexibility.

[0018] 2. The annular bar is pushed and pulled by the extension and retraction of the hydraulic cylinder. The annular bar drives the drive rod to move through the connecting rod. When the drive rod pushes the hollow rod towards the opening of the spray tube, the connecting sleeve causes the spray angle of the atomizing nozzle to deflect towards the outer edge of the annular tube. When the drive rod pulls the hollow rod into the spray tube, the connecting sleeve causes the atomizing nozzle to deflect towards the inner side of the annular tube. This can concentrate the dust suppression mist towards a specific direction or area, corresponding to different spray intensities, and taking into account both regional and local dust suppression tasks.

Detailed Implementation

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.

[0026] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0027] As shown in Figures 1-5, a mobile dust suppression fog cannon vehicle includes a mobile vehicle 1 and a spray assembly 5. The mobile vehicle 1 is equipped with a mounting platform 2 that can change the orientation of the spray cylinder 3. The spray cylinder 3 is mounted on the mounting platform 2. The spray assembly 5 is located inside the spray cylinder 3. The spray cylinder 3 is equipped with fan blades 4 inside. A water tank 7 is fixed on the top of the mobile vehicle 1.

[0028] The spray assembly 5 includes a mounting frame 51 fixed inside the spray cylinder 3. One end of the mounting frame 51 is fixed with a plurality of annular and equidistantly distributed hollow strips 52. The interior of the mounting frame 51 has a plurality of grooves 53. An expansion member is provided on the exterior of the mounting frame 51. An annular tube 54 with an adjustable diameter is mounted on the expansion member. The annular tube 54 includes a plurality of rigid pipes 541. A telescopic tube 542 connects two adjacent rigid pipes 541. The water tank 7 is connected to one of the rigid pipes 541 through a water supply mechanism, which consists of a water pump and a water supply pipe. The water pump inlet is connected to the interior of the water tank 7 through a water suction pipe, and the water outlet is fixed to one end of the water supply pipe. Atomizing nozzles 59 are provided on the exterior of the plurality of rigid pipes 541. Each atomizing nozzle 59 includes a flexible hose 591 fixed to the exterior of the rigid pipe 541. One end of the flexible hose 591 is fixed with an atomizing nozzle 592.

[0029] The expansion component includes a movable seat 55 that slides inside the mounting frame 51, an electric push rod 56 that is fixed outside the mounting frame 51, and lifting bars 57 that slide inside multiple hollow bars 52 respectively. The number of hollow bars 52, lifting bars 57, and rigid pipes 541 are the same and their positions are opposite. The lifting bars 57 are located inside the annular pipe 54. One end of each of the multiple lifting bars 57 is fixed outside the multiple rigid pipes 541. Expansion bars 58 rotate between each of the multiple lifting bars 57 and the movable seat 55. One end of the electric push rod 56 is fixed outside the movable seat 55 and is used to drive the movable seat 55 to move along the groove 53.

[0030] The spray assembly 5 also includes a deflector disposed outside the rigid pipe 541. The deflector is used to change the spray angle of the atomizing nozzle 592 and change the density of the water mist spray. The spray cylinder 3 has multiple through slots 6 inside, and the positions of the through slots 6 correspond to the positions of the rigid pipe 541. The deflector includes an annular strip 510 that slides outside the spray cylinder 3, multiple hydraulic cylinders 511 that are fixed outside the spray cylinder 3, connecting sleeves 512 that rotate outside the multiple rigid pipes 541 respectively, and two hollow limiting strips 513 that are fixed to one end of the lifting strip 57 respectively. Multiple hoses 591 are fixed inside the multiple connecting sleeves 512 respectively.

[0031] One end of the telescopic rod of multiple hydraulic cylinders 511 is fixed to the outside of the annular bar 510 to drive the annular bar 510 to move outside the spray cylinder 3. Multiple connecting rods 514 that can slide inside the annular bar 510 are inserted inside the annular bar 510. Multiple connecting rods 514 are respectively inserted inside multiple through slots 6. One end of multiple connecting rods 514 extending into the spray cylinder 3 is fixed with a drive rod 515. One end of the drive rod 515 slides through two short shafts inside two hollow limit bars 513 on the same lifting bar 57. Two hollow rods 516 are fixed below multiple connecting sleeves 512. The other end of the drive rod 515 slides through two connecting shafts inside the two hollow rods 516 located below the same connecting sleeve 512.

[0032] During use, when spraying, the electric push rod 56 extends and retracts, pushing the movable seat 55 within the mounting frame 51. As the movable seat 55 moves, it causes the connected expanding and contracting strip 58 to gradually expand or contract outside the mounting frame 51. When the expanding and contracting strip 58 expands, it pushes the lifting strip 57 within the hollow strip 52, increasing their combined length. This expands the rigid pipe 541 outwards. As the rigid pipe 541 expands, the telescopic tube 542 extends, maintaining the overall sealing of the annular pipe 54 without affecting the adjustment of the overall diameter and circumference of the annular pipe 54. When the expanding strip 58 retracts, it pulls the lifting strip 57 to move within the hollow strip 52, reducing the total length of both. This causes the rigid pipe 541 to retract inward. When the rigid pipe 541 retracts, the telescopic tube 542 folds and shortens. The diameter of the annular tube 54 is adjustable, allowing for adjustments to the spray concentration based on different environments and cleaning needs, meeting diverse requirements and offering high flexibility. Furthermore, as the lifting strip 57 moves, it drives the drive rod 515 and connecting rod 514 to change position as the annular tube 54 expands and retracts via the hollow limiting strip 513, ensuring that the drive rod 515 remains in the position within the hollow rod 516.

[0033] The annular bar 510 can be moved along the through groove 6 outside the spray cylinder 3 by extending and retracting the hydraulic cylinder 511. The annular bar 510 drives the internally inserted connecting rod 514 to move in the through groove 6. The connecting rod 514 then drives the drive rod 515 to move along the direction of the hollow limit bar 513. One end of the drive rod 515 moves in the hollow rod 516. When the drive rod 515 pushes the hollow rod 516 towards the opening of the spray cylinder 3, it will cause the connecting sleeve 512 to deflect towards the periphery of the annular tube 54, thereby driving... The spray angle of the atomizing nozzle 592 deflects towards the outer edge of the annular tube 54. Conversely, when the drive rod 515 pulls the hollow rod 516 into the spray cylinder 3, it will cause the connecting sleeve 512 to deflect towards the inner side of the annular tube 54, thereby causing the spray angle of the atomizing nozzle 592 to deflect towards the inner side of the annular tube 54. This allows the spray to cover a wider or more precise area, concentrate the dust-suppressing mist towards a specific direction or area, improve dust suppression efficiency, and meet different spray intensities, taking into account both regional and local dust suppression tasks.

After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
