Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of freight vehicles, in particular to a self-dust-lowering vehicle. BACKGROUND

[0002] Haze is a weather phenomenon produced by PM2.5 and other size particles, dust, aerosol and other particles floating in the atmosphere under certain temperature and humidity conditions in a relatively stable state. Haze has a great impact on people's health and daily life. Among various sources of air particulate pollution, freight trucks are an important factor. Large trucks inevitably vibrate during travel, although they are covered with canvas and other coverings, but the sand or other powder cargo in the truck still causes dust. Moreover, when the truck is driving on the road, the wheels will also interact with the ground to stir up the ground dust and cause dust, and the amount of dust is much higher than that of conventional vehicles. The conventional freight truck does not have a dust-lowering function during driving. In addition, the dust generated during the loading and unloading of the freight truck has a bad impact on the environment. Spraying water mist on the top of the freight truck can effectively reduce the dust generated during the loading and unloading of the freight truck, but the conventional freight truck does not have this function, and it needs to be coordinated with a separate water mist generating device or vehicle to reduce the amount of dust, which is not only very cumbersome, but also the loading and unloading site may not have a separate water mist generating device or vehicle. At the same time, the water mist generated by the conventional separate water mist generating device or vehicle usually has a short range and a small range, so one such device or vehicle may not be able to meet the dust-lowering effect of the freight truck at all.

[0003] The utility model patent with the application number 201920397836.8 discloses a self-dust-removing freight truck. The patent application uses a high-pressure water pump to take water from a water tank and distribute it to the first group of micro-fine atomizing nozzles, the second group of micro-fine atomizing nozzles and the third group of micro-fine atomizing nozzles through the first pipeline, the second pipeline and the third pipeline respectively. The water mist sprayed by the first group of atomizing nozzles reduces the dust generated upward in the truck compartment, the second group of nozzles reduces the dust generated by the rotation of the wheels, and the third group of nozzles reduces the dust generated backward during the forward movement of the vehicle. However, in actual use, the first group of micro-fine atomizing nozzles and the first pipeline easily affect the loading and unloading of the goods on the freight truck and the opening and closing of the coaming, causing damage to the first group of micro-fine atomizing nozzles and the first pipeline. At the same time, the second group of micro-fine atomizing nozzles and the third group of micro-fine atomizing nozzles are not reasonably distributed, and the dust-lowering effect is not ideal, and different dust-lowering modes cannot be adopted according to different working scenes and dust pollution levels. SUMMARY

[0004] The self-dust-reducing vehicle does not affect loading and unloading of goods on the freight vehicle and opening and closing of the cargo compartment, is convenient to use, can adopt different dust-reducing modes according to different working scenes and dust pollution degrees, has good dust-reducing effect, and saves electric energy and water energy.

[0005] To achieve the above object, the present application adopts the following technical scheme:

[0006] The self-dust-reducing vehicle comprises a vehicle body, a cargo compartment and wheels, a cargo compartment dust-reducing device and a vehicle body dust-reducing device, the cargo compartment dust-reducing device comprises at least one water mist generating device arranged at the side of the cargo compartment close to the vehicle head, the water mist generating device comprises rotatable fan blades and a first nozzle arranged behind the fan blades, the rotatable fan blades blow the water mist sprayed by the first nozzle to the upper side of the cargo compartment, the first nozzle is connected with a high-pressure water pump through a first pipeline, and the water inlet of the high-pressure water pump is connected with a water tank, the vehicle body dust-reducing device comprises a plurality of second nozzles, the second nozzles are connected with the high-pressure water pump through a second pipeline, the second nozzles comprise a plurality of side nozzles arranged at the two sides of the vehicle body, a first valve is arranged on the first pipeline, and a second valve is arranged on the second pipeline.

[0007] Preferably, the vehicle further comprises a main dust-reducing device, the main dust-reducing device comprises a plurality of groups of third nozzles arranged at the rear side of the vehicle body, the third nozzles are connected with the high-pressure water pump through a third pipeline, and a third valve is arranged on the third pipeline.

[0008] Preferably, the water mist generating device further comprises a substantially cylindrical cover body, a first rotating connecting shaft pipe and a second rotating connecting shaft pipe, the first nozzle is provided with at least two first nozzles arranged at the two sides of the first rotating connecting shaft pipe and penetrating through the first rotating connecting shaft pipe, the first nozzle is connected with the second rotating connecting shaft pipe through the first rotating connecting shaft pipe, the second rotating connecting shaft pipe is connected with the first pipeline through a rotating joint, the second rotating connecting shaft pipe is fixed on a bearing and is fixedly connected with the fan blades, the fan blades are arranged inside the cover body, and the bearing is arranged on the cover body.

[0009] Preferably, the side nozzles are arranged at the two sides below the cargo compartment, and the side nozzles are arranged obliquely towards the outside of the vehicle body; the second nozzles further comprise rear nozzles arranged at the rear side of the cargo compartment.

[0010] Preferably, the first nozzle is provided with two first nozzles, the cross sections of the two first nozzles and the cover body form an angle of 10°-25°, and the two first nozzles are arranged oppositely.

[0011] Preferably, the third nozzle is a rotating nozzle.

[0012] Preferably, it also includes a wheel cleaning device, which includes several sets of fourth nozzles arranged in front of or behind the wheel and tilted toward the wheel. The fourth nozzles are connected to a high-pressure water pump via a fourth pipe, and a fourth valve is provided on the fourth pipe.

[0013] Preferably, the system also includes a dust monitoring device and a control system, wherein the dust monitoring device is connected to the control system, and the control system is also connected to the high-pressure water pump, the first valve, the second valve, the third valve, and the fourth valve respectively.

[0014] Preferably, it also includes a positioning device and a control terminal, wherein the positioning device and the dust monitoring device can transmit the collected signals to the control terminal, and the control terminal is connected to the control system.

[0015] More preferably, the rotating nozzle is provided with three to five fifth nozzles.

[0016] In the above technical solution, by setting first nozzles at an angle of 10°-25° to the cross-section of the cover on both sides of the first rotating connecting shaft tube, the high-pressure water pump sprays water mist from the two first nozzles through the first pipe, generating a reverse thrust that interacts with each other, and then rotates the two first nozzles through the bearing. Since the second rotating connecting shaft tube is fixed on the bearing and fixed to the fan blade, the reverse thrust generated by the two first nozzles interacts with each other, causing the fan blade to rotate at high speed, thereby sending the water mist sprayed by the two first nozzles to a greater distance, greatly increasing the dust suppression range of the water mist generating device. By simply placing the water mist generating device on the side of the cargo box near the front of the vehicle, dust suppression can be achieved over the entire cargo box, without affecting the loading and unloading of goods on the self-dust-suppressing vehicle or the opening and closing of the cargo box panels, making it convenient to use. By installing multiple side nozzles on both sides of the vehicle body, with the nozzles angled outwards, this self-dust-reducing vehicle can effectively suppress dust generated on both sides of the vehicle body and towards the wheels during operation, rather than being limited to the vicinity of specific wheels. It can effectively suppress dust generated by bumps, vibrations, or the airborne dust from sand and other powdery goods during vehicle movement. Since dust typically increases with vehicle speed, and at higher speeds, dust usually accumulates behind the vehicle, the effectiveness of the side nozzles decreases. At this point, a third nozzle is activated. Because the third nozzle is a rotating nozzle with three to five fifth nozzles on each rotating nozzle, its spray range and height are significantly greater than that of the side nozzles, effectively reducing dust generation. A wheel cleaning device specifically cleans the wheels upon entry and exit, further reducing dust generated by the wheels. The dust monitoring device monitors dust data in real time and transmits the data to the control system. The control system then intelligently controls the opening of the first, second, third, and fourth valves, and controls whether each nozzle sprays according to different dust data, forming different dust suppression schemes. This results in more targeted dust suppression, better dust suppression effect, and better energy saving. BRIEF DESCRIPTION OF DRAWINGS

[0021] The application will be further described below with reference to the drawings:

[0022] As Figs. 1 to 4As shown, the self-dust-reducing vehicle includes a vehicle body 1, the vehicle body 1 including a vehicle head 10, a cargo compartment 20, vehicle wheels 30, a cargo compartment dust-reducing device 40, and a vehicle body dust-reducing device 50, wherein the cargo compartment dust-reducing device 40 includes at least one water mist generating device 41 arranged on the side of the cargo compartment 20 close to the vehicle head 10, the water mist generating device 41 including a rotatable fan blade 42 and a first nozzle 43 arranged behind the fan blade 42, so that the water mist sprayed by the first nozzle 43 can be blown to a distance far above the cargo compartment 20 by the rotating fan blade 42, greatly increasing the dust-reducing range of the water mist generating device 41, and realizing that the water mist sprayed by one water mist generating device 41 can penetrate the entire distance of the cargo compartment 20, and only one or several water mist generating devices 41 arranged side by side on the side of the cargo compartment 20 close to the vehicle head 10 can realize dust reduction of the dust raised above the entire cargo compartment 20, without affecting the loading and unloading of the cargo of the self-dust-reducing vehicle and the opening and closing of the surrounding plate of the cargo compartment 20, and being convenient to use. The first nozzle 43 is connected to a high-pressure water pump 70 through a first pipeline 44, and the water inlet of the high-pressure water pump 70 is connected to a water tank 71; the vehicle body dust-reducing device 50 includes a plurality of second nozzles 51, the second nozzles 51 being connected to the high-pressure water pump 70 through a second pipeline 52, and the second nozzles 51 including a plurality of side nozzles 53 arranged on both sides of the vehicle body 1, the side nozzles 53 being arranged on both sides below the cargo compartment 20 and being arranged obliquely towards the outside of the vehicle body 1, without affecting the loading and unloading of the cargo of the self-dust-reducing vehicle and the opening and closing of the surrounding plate of the cargo compartment 20, and enabling the self-dust-reducing vehicle to reduce dust raised on both sides of the entire vehicle body 1 and towards the side of the vehicle wheels 30 to a greater range during driving, rather than being limited to the vicinity of the specific vehicle wheels 30, and enabling dust raised during driving of the self-dust-reducing vehicle due to jolting and vibration or flying of powder cargo such as sand to be reduced. In the embodiment, the self-dust-reducing vehicle further includes a main dust-reducing device 60, the main dust-reducing device 60 including a plurality of groups of third nozzles 61 arranged on the rear side of the vehicle body 1, the third nozzles 61 being connected to the high-pressure water pump 70 through a third pipeline 62. In the embodiment, the third nozzles 61 are rotary nozzles, and the range and height of the water mist sprayed by the rotary nozzles are much greater than those of conventional nozzles. Since the faster the vehicle speed, the more dust raised, when the vehicle speed is high, dust is usually raised behind the vehicle, so the dust-reducing effect of the side nozzles 53 will decrease accordingly at this time, and the third nozzles 61 are opened at this time. Since the third nozzles 61 are rotary nozzles, and further, three to five fifth nozzles (not shown in the drawing) can be further arranged on each rotary nozzle, the amount of water mist sprayed by the third nozzles 61 is further increased, and the amount of dust raised is effectively reduced. First, second, and third valves 441, 521, and 621 are arranged on the first, second, and third pipelines 44, 52, and 62 respectively, and whether the nozzles spray water is controlled by the valves, thereby adapting to different working conditions.

[0023] In a preferred embodiment, the water mist generating device 41 further comprises a substantially cylindrical cover 45, a first rotating connecting shaft tube 46 and a second rotating connecting shaft tube 47, the first nozzle 43 is provided with at least two, which are arranged on both sides of the first rotating connecting shaft tube 46 and penetrate the first rotating connecting shaft tube 46, the first nozzle 43 is connected with the second rotating connecting shaft tube 47 through the first rotating connecting shaft tube 46, the second rotating connecting shaft tube 47 is connected with the first pipeline 44 through a rotating joint 48, the second rotating connecting shaft tube 47 is fixed on a bearing 49 and connected with the fan blade 42, the fan blade 42 is arranged inside the cover 45, the bearing 49 is fixed on the cover 45, and the rotating joint 48 is a commonly used pipeline connecting device, and the connected pipeline can rotate relatively. In this embodiment, the first nozzle 43 is provided with two, and the cross section of the two first nozzles 43 and the cover 45 forms an angle of 10°-25°, and the two first nozzles 43 are arranged oppositely. When the high-pressure water pump 70 sprays water mist from the two first nozzles 43 through the first pipeline 44, the two first nozzles 43 will generate reverse thrust, and the reverse thrust will interact through the bearing 49 to achieve the purpose of rotating the two first nozzles 43 around the bearing 49. Since the second rotating connecting shaft tube 47 is fixed on the bearing 49 and connected with the fan blade 42, the interaction of the reverse thrust generated by the two first nozzles 43 makes the fan blade 42 rotate at high speed, so that the water mist sprayed by the two first nozzles 43 is sent to a farther distance, greatly increasing the dust-settling range of the water mist generating device 41. At the same time, the driving of the fan blade 42 only relies on the interaction of the reverse thrust generated by the two first nozzles 43, further saving electric energy. The cover 45 can be further adjusted in angle and inclined to be arranged near the head side of the cargo compartment 20, further adjusting the height and dust-settling range of the water mist sprayed by the first nozzle 43, adapting to different dust-settling needs.

[0024] In a preferred embodiment, the second nozzle 51 further comprises a plurality of rear nozzles 54 arranged on the rear side of the cargo compartment 20, further improving the dust-settling effect of the vehicle body dust-settling device 50.

Through the wheel cleaning device 80, the wheels 30 are cleaned in and out of the field, further reducing the dust generated by the wheels 30.

[0026] In a preferred embodiment, to further increase the spraying effect of the second nozzle 51, improve the dust-settling effect of the second nozzle while reducing the amount of water used, the opening of the second nozzle 51 is substantially fan-shaped and a No. 3, No. 4 or No. 5 atomizing nozzle is selected, the aperture of the No. 3, No. 4 and No. 5 atomizing nozzle is 0.3mm, 0.4mm and 0.5mm respectively, so that the water mist sprayed by the second nozzle 51 forms a micro-mist effect, reduces the amount of water used, avoids muddy roads while further prolonging the time the water mist stays in the air, further improving the dust-settling effect. Similarly, the fifth nozzle can also be selected as a No. 3, No. 4 or No. 5 or even a No. 6 atomizing nozzle, further improving the dust-settling effect of the main dust-settling device 60.

[0027] In a preferred embodiment, the self-dust-settling vehicle also includes a dust-raising monitoring device 90 and a control system (not shown in the figure), the dust-raising monitoring device is connected to the control system, the control system is also connected to the high-pressure water pump 70, the first valve 441, the second valve 521, the third valve 621 and the fourth valve 821, the dust-raising monitoring device monitors the dust-raising data in real time and transmits the monitoring data to the control system, the control system intelligently controls the opening of the first valve 441, the second valve 521, the third valve 621 and the fourth valve 821, and then controls whether each nozzle sprays water according to different dust-raising data, forming different dust-settling schemes, which is more targeted, has better dust-settling effect and better energy-saving effect. The dust-raising monitoring device 90 can be further provided with two or more, respectively detecting the dust-raising data above the cargo compartment 20 and the dust-raising data below the cargo compartment 20, more accurately controlling whether each nozzle sprays water, forming different dust-settling schemes, further improving the targeting of dust-settling. In a preferred embodiment, the self-dust-settling vehicle also includes a positioning device (not shown in the figure) and a control terminal (not shown in the figure), the positioning device can accurately and effectively monitor the travel trajectory of the self-dust-settling vehicle and transmit the motion trajectory of the self-dust-settling vehicle to the control terminal, the dust-raising monitoring device transmits the collected signals to the control system, the control system controls the opening and closing of the corresponding valves, realizing different dust-settling modes for different dust pollution concentrations, the control system is connected to the control terminal, so as to realize the monitoring of the travel trajectory of the self-dust-settling vehicle in the control terminal while detecting the running state of each device.

[0028] In the above technical solution, when the dust monitoring device detects that the dust data above the cargo compartment 20 is too large, or when the self-dust-reducing vehicle is loading or unloading, the first valve 441 is opened, the high-pressure water pump 70 sprays water mist from the two first nozzles 43 through the first pipeline 44 and generates a reverse thrust interaction to realize the rotation of the two first nozzles 43 through the bearing 49, and the fan blades 42 also rotate at high speed with the bearing 49, so that the water mist sprayed by the two first nozzles 43 is sent to a farther distance, the dust-reducing range of the water mist generating device 41 is greatly increased, and the dust-reducing purpose of the entire cargo compartment 20 is realized, which does not affect the loading and unloading of the goods on the self-dust-reducing vehicle and the opening and closing of the cargo compartment 20, and is convenient to use. When the dust monitoring device detects that the dust data below the cargo compartment 20 is large, or when the self-dust-reducing vehicle generates a large amount of dust during driving, the second valve 521 is opened, and the second nozzle 51 generates a larger range of dust reduction on both sides of the entire vehicle body 1 and the side facing the wheels 30, instead of being limited to a specific wheel 30. The dust generated by the self-dust-reducing vehicle during driving due to bumps, vibrations or flying dust of powder goods, and the dust generated by the wheels and the ground can all achieve the dust-reducing purpose; when the dust monitoring device detects that the dust data below the cargo compartment 20 is larger, the third valve 621 is opened, and the water mist sprayed by the rotating nozzle has a much larger range than the water mist sprayed by the conventional nozzle, so that the amount of dust is effectively reduced. The wheel cleaning device 80 is used to clean the wheels 30 in and out of the field, further reducing the dust generated by the wheels 30. The control system intelligently controls the opening of the first valve 441, the second valve 521, the third valve 621 and the fourth valve 821, and then controls whether each nozzle sprays water mist according to different dust data, forming different dust-reducing schemes, which are more targeted, have better dust-reducing effect and better energy-saving effect.
