Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a dust suppression vehicle. Background Art

[0002] At present, a large amount of dust is generated during the construction process of construction sites. The dust reduction device of traditional technology generally adopts a conventional structure cannon fog machine. The dust removal principle of the cannon fog machine is that water enters the liquid pressurizing device and is pressurized into high pressure, and then sent to the atomizing nozzle to atomize the liquid into fine mist particles. Since the diameter of the mist droplets is very small, they can float in the air for a long time. When the cold mist droplets hit the dust suspended in the air, they will adhere to the dust and gradually condense. When the weight of the dust suspended in the air increases to a certain level and the gravity is greater than the buoyancy, it will fall to the ground, thereby achieving the purpose of spray dust removal to purify the air and improve the ecological environment.

[0003] For example, the patent document with publication number CN116139622A discloses a construction dust reduction device, which includes a dust reduction device base plate and a nozzle bearing seat. When in use, the height of the lifting platform can be adjusted by a provided lifting mechanism, thereby realizing height adjustment of the nozzle bearing seat and the dust reduction nozzle, so that the dust reduction nozzle can be adjusted according to the on-site work intensity and dust height, thereby ensuring a good dust treatment effect on the site;

[0004] Another example is a dust reduction structure and a dust reduction construction method for construction disclosed in the patent document with publication number CN117563364A. When in use, when the rotating frame rotates at a set speed and within a set angle range, the driven gear is meshed and connected with the fixed gear ring, so that on the one hand, the dust reduction swing cylinder can reciprocate within the set angle range, and on the other hand, the shaft sleeve can reciprocate within the set angle range.

[0005] Although the above scheme can improve the coverage of the spray to a certain extent, in order to enable the water mist to reach an effective range, continuous power supply is required to keep the cannon fog machine running at high power, which consumes significant energy. Summary of the invention

[0006] The purpose of the present invention is to overcome the defects of the prior art and provide a dust suppression vehicle to solve the problem of significant energy consumption caused by the high-power operation of the cannon fog machine in the prior art to increase the spray coverage range.

[0007] To achieve the above-mentioned purpose, the present invention provides a dust suppression vehicle, comprising a mobile vehicle, a water pumping system, a fog machine, a conical seat and a swinging nozzle;

[0008] The water pumping system and the fog machine are installed on the mobile vehicle, and the water pumping system supplies water to the fog machine;

[0009] The conical seats are evenly arranged in a plurality along the circumference of the air outlet of the cannon fog machine;

[0010] The oscillating nozzle is supplied with water by the water pump system and is rotatably connected to the conical seat; the spray end of the oscillating nozzle can selectively rotate to one of the inner side and the outer side of the air outlet as the oscillating nozzle rotates on the conical seat.

[0011] By adopting this technical solution, a conical seat and a swinging nozzle are added and installed at the air outlet position of the cannon fog machine on the basis of the original cannon fog machine. The rotation of the swinging nozzle on the conical seat can selectively make its spray end be located on the inside or outside of the air outlet. During normal operation, the spray end of the swinging nozzle is located on the inside of the air outlet, and combined with the spray of the cannon fog machine itself, the spray volume at the air outlet position of the cannon fog machine can be increased; when the spray end of the swinging nozzle is rotated to be located outside the air outlet, the spray end located on the outside can be sent forward by the natural wind outside the cannon fog machine, thereby increasing the spray range and solving the problem of increased energy consumption required to increase the spray range.

[0012] Furthermore, the oscillating nozzle includes a V-shaped rod rotatably connected to the conical seat at a corner, and a first outer nozzle and a second outer nozzle respectively installed at both ends of the V-shaped rod; the first outer nozzle and the second outer nozzle correspond to the spray ends of the oscillating nozzle; the number of oscillating nozzles is increased to two, so that the adjustment is more flexible, and accordingly, one of the first outer nozzle and the second outer nozzle can be rotated to the outside of the air outlet, which can increase the spray range by rotating the nozzle to the outside of the air outlet, and increase the spray amount by leaving the nozzle on the inside of the air outlet; the first outer nozzle and the second outer nozzle can also be rotated to the outside of the air outlet at the same time, increasing the spray range while ensuring the spray amount within the increased range; the first outer nozzle and the second outer nozzle can also be left on the inside of the air outlet at the same time, greatly increasing the spray amount passing through the air outlet.

[0013] Furthermore, it also includes a supporting ring cover and an air guide plate;

[0014] The support ring cover is arranged concentrically with the air outlet and is located at the periphery of the air outlet, and the support ring cover is located at the outer side of the conical seat;

[0015] The air guide plate is arranged between the support ring cover and the air outlet, and is fixed to the support ring cover and the air outlet respectively.

[0016] By adopting this technical solution, the support ring cover and the wind guide plate cooperate to guide the natural wind outside the fog machine, so that the natural wind can act more on the conical seat, and then the natural wind can act more on the V-shaped rod connected to the conical seat and the first outer nozzle and the second outer nozzle connected at both ends of the V-shaped rod, so as to achieve the purpose of spraying fog from the first outer nozzle or the second outer nozzle with the help of natural wind.

[0017] Furthermore, the air guide plate is a V-shaped plate, and the opening direction of the air guide plate is the same as the direction of the air outlet.

[0018] By adopting this technical solution, the distance between adjacent air guide plates decreases from back to front. After the natural wind enters, it guides and increases the flow rate, providing sufficient delivery force for the mist sprayed by the first outer nozzle or the second outer nozzle located outside the air outlet.

[0019] Furthermore, it also includes fan blades, racks, connecting springs and external gears;

[0020] The fan blades correspond to the conical seats one by one and are rotatably connected to the periphery of the supporting ring cover;

[0021] One end of the rack is limitedly slidably connected to the fan blade, and the other end is slidably connected to the conical seat, and the side portion of the rack is meshed with the external gear, and the external gear is coaxially fixed with the rotating shaft of the V-shaped rod;

[0022] The connecting spring is sleeved on the rack, one end of the connecting spring is fixed to the conical seat, and the other end is fixed to the rack;

[0023] When the connecting spring is in a normal state, the fan blade is inclined toward one side of the air outlet, and the first outer nozzle and the second outer nozzle are both located on the inner side of the air outlet.

[0024] By adopting this technical solution, when the fan blades are subjected to sufficient natural wind force, they can press down the rack to compress the connecting spring, and at the same time push the outer gear to rotate to drive the V-shaped rod to rotate, so that the first outer nozzle connected to the V-shaped rod rotates to the outside of the air outlet, or the second outer nozzle rotates to the outside of the air outlet, or the first outer nozzle and the second outer nozzle rotate to the outside of the air outlet at the same time, and cooperate with the natural wind to achieve the purpose of automatically increasing the spray range; when the natural wind force becomes smaller, the first outer nozzle and the second outer nozzle can be reset under the action of the connecting spring, and cooperate with the cannon fog machine to increase the spray amount at the air outlet position.

[0025] Furthermore, the mobile vehicle comprises a frame, wheels and a hand push rod;

[0026] The frame is used to support and install the water pump system and the fog machine;

[0027] The wheels are mounted on the bottom of the frame;

[0028] The hand push rod is installed on the top of the frame at a side facing away from the air outlet.

[0029] Furthermore, the water pumping system includes a water tank and a water pump mounted on the frame, and the water pump draws water stored in the water tank to supply water to the cannon fog machine, the first outer nozzle and the second outer nozzle.

[0031] Furthermore, the cannon fog machine includes a support tube, an air inlet tube, a spray tube, a fixed support rod, a spray seat and an inner nozzle;

[0032] The air inlet cylinder, the support cylinder and the spray cylinder are sequentially connected and communicated from back to front, wherein a fan is installed inside the air inlet cylinder, and the front end of the spray cylinder is the air outlet;

[0033] The spray seat is connected to the inside of the spray barrel through the fixed support rod, and a plurality of inner nozzles are connected to the spray seat, and the plurality of inner nozzles are all supplied with water by the water pump system.

[0034] By adopting this technical solution, a basic cannon fog machine structure is formed.

[0035] Furthermore, the bottom of the support tube is rotatably mounted on a rotatable support sleeve through support legs, and the rotatable support sleeve is rotatably mounted on the water tank.

[0036] By adopting this technical solution, the cannon fog machine has the ability of bidirectional rotation compared to the water tank, which provides the prerequisite for the vertical and horizontal angle adjustments of the cannon fog machine.

[0037] Furthermore, a height control component and an angle control component are provided between the fan and the frame;

[0038] The height control component is used to adjust the height of the fan;

[0039] The angle control component is used to adjust the angle of the fan.

[0040] By adopting this technical solution, after the height control component adjusts the height of the fan, the spray barrel at the front end of the fog machine is lifted or lowered due to the rotation of the middle support tube of the fog machine compared to the water tank, thereby completing the vertical angle adjustment of the fog machine; after the angle control component adjusts the angle of the fan, the spray barrel at the front end of the fog machine is swung left and right due to the rotation of the middle support tube of the fog machine compared to the water tank, thereby completing the horizontal angle adjustment of the fog machine.

[0041] Compared with the prior art, the present invention has the following beneficial effects:

[0042] 1. On the basis of the original cannon fog machine, a swinging nozzle that can rotate inwards and outwards is set at its air outlet. When it is rotated to the inside of the air outlet, it can increase the spray volume of the cannon fog machine's air outlet. When it is rotated to the outside of the air outlet, it can cooperate with natural wind to increase the spray range of the cannon fog machine's air outlet, thereby increasing the spray range without increasing energy consumption.

[0043] 2. The linkage mechanism is formed by the fan blades, racks, connecting springs and external gears, so that the swing nozzle can automatically rotate to the outside of the air outlet under the action of natural wind, so as to increase the spray volume with the help of natural wind and realize the automation of increasing the spray range.
