Detailed Embodiments

[0028] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present utility model, and should not be construed as limiting the present utility model.

[0029] Combined with Figure 1 , the cleaning vehicle 100 according to an embodiment of the present utility model includes: a vehicle body 10, a first box body 21, a second box body 22, and a spraying device 31. Specifically, the first box body 21 is disposed on the vehicle body 10, the second box body 22 is disposed on the vehicle body 10 and communicates with the first box body 21. The first box body 21 is used for storing water, the second box body 22 is used for storing water, the spraying device 31 is connected to the first box body 21 and the second box body 22, and the first box body 21 and the second box body are adapted to supply water to the spraying device 31. That is to say, the cleaning vehicle 100 has two box bodies at the same time, which can increase the water output, facilitate increasing the duration of the cleaning operation, and improve the cleaning efficiency. Specifically, both the first box body 21 and the second box body 22 can supply water to the spraying device 31, thereby increasing the water spraying amount of the spraying device 31, increasing the water storage capacity of the cleaning vehicle 100, facilitating increasing the cleaning duration or the cleaning amount, reducing the frequency of adding water, facilitating reducing the use cost, and improving the cleaning efficiency.

[0030] For the cleaning vehicle 100 according to an embodiment of the present utility model, by simultaneously providing the first box body 21 and the second box body 22, and both the first box body 21 and the second box body 22 can supply water to the spraying device 31, the water supply amount can be increased, which is beneficial to improving the cleaning efficiency.

[0031] Combined with Figure 1 , in some embodiments of the present utility model, the cleaning vehicle 100 includes a lifting device 50. The lifting device 50 is disposed on the second box body 22 and rises or falls relative to the second box body 22. The spraying device 31 is disposed on the lifting device 50, whereby the lifting height of the spraying device 31 can be increased. The lifting device 50 is directly disposed above the second box body 22, which can increase the initial height of the lifting device 50. In the case of reaching the same lifting height, the lifting range of the lifting device 50 can be reduced, so that the size of the lifting device 50 can also be reduced, which is beneficial to the space layout.

[0032] Specifically, in the related art, the lifting device is directly connected to the vehicle body, and the lifting device moves in the up and down direction to realize the raising and lowering of the spraying device. In this way, the space occupied by the lifting device is relatively large. In the present application, the second box body 22 is placed on the vehicle body 10, and the lifting device 50 and the spraying device 31 can be directly arranged above the second box body 22. On the one hand, the height of the spraying device 31 is increased, so that the size and the occupied space of the lifting device 50 can be reduced; on the other hand, the second box body 22 can also be used for storing water, thereby increasing the water loading capacity of the vehicle.

[0033] Optionally, the lifting device 50 can be a scissor-type lifting device 50.

[0034] In some embodiments of the present utility model, the first box body 21 is connected to the spraying device 31 through a first pipeline 41, and the second box body 22 is connected to the spraying device 31 through a second pipeline 42. The first box body 21 and the second box body 22 supply water to the spraying device 31 respectively. That is to say, the first box body 21 and the second box body 22 can be respectively connected to the spraying device 31, so as to supply water to the spraying device 31 respectively, thereby improving the flexibility during application. Specifically, the first pipeline 41 is provided with a first valve, and the first valve is adapted to connect or disconnect the first pipeline 41 to connect or disconnect the first box body 21 and the spraying device 31; the second pipeline 42 is provided with a second valve, and the second valve is adapted to connect or disconnect the second pipeline 42 to connect or disconnect the second box body 22 and the spraying device 31.

[0035] Furthermore, in some embodiments of the present utility model, the first box body 21 includes a first water level detector, and the first water level detector transmits signals to the first valve; the second box body 22 includes a second water level detector, and the second water level detector transmits signals to the second valve. Thus, when the water level detectors of the first box body 21 and the second box body 22 reach a predetermined value, the first water level detector or the second water level detector can be opened or closed. The first water level detector can also transmit signals to the second valve, and the second water level detector can also transmit signals to the first valve. For example, when the first box body 21 is short of water, the first valve is closed and the second valve is opened, so that the second box body 22 is connected to the spraying device 31.

[0036] In some embodiments of the present utility model, the first box body 21 communicates with the second box body 22. The first box body 21 is connected to the spraying device 31 through the first pipeline 41, and the first box body 21 is adapted to supply water to the spraying device 31. In other words, the second box body 22 can replenish water to the first box body 21. The spraying device 31 is only connected to the first box body 21, which can simplify the structure and facilitate manufacturing. Specifically, the second pipeline 42 is connected to the first pipeline 41, and a control valve is provided on the second pipeline 42. The control valve is adapted to connect or disconnect the first pipeline 41 and the second pipeline 42. Thus, the water in the second box body 22 can enter the first box body 21 to deliver the water in the second box body 22 to the first box body 21.

[0037] Combined with Figure 3 , in some embodiments of the present utility model, one end of the first pipeline 41 is connected to the second pipeline 42, and the other end is connected to the first box body 21. One end of the second pipeline 42 is connected to the first pipeline 41, and the other end is connected to the second box body 22. The cleaning vehicle 100 further includes a control valve 85 provided on the second pipeline 42. The control valve 85 is adapted to connect or disconnect the first pipeline 41 and the second pipeline 42. Specifically, a high-pressure water pump 62 is provided in the first box body 21. The high-pressure water pump 62 can supply high-pressure water to the spraying device 31. Therefore, the first pipeline 41 can be connected to the spraying device 31. The first pipeline 41 is connected to the second pipeline 42, and the high-pressure water can be sent to the second box body 22. When the control valve 85 is opened, the high-pressure water can enter the second box body 22 from the first pipeline 41 through the second pipeline 42, and the high-pressure water then sends the water in the second box body 22 to the first box body 21 through the second pipeline 42. Thus, the water supply from the second box body 22 to the first box body 21 can be realized, and only the original high-pressure water pump 62 in the first box body 21 is utilized, which is beneficial to simplifying the structure and saving energy.

[0038] Alternatively, the first box body 21 communicates with the second box body 22. The second box body 22 is connected to the spraying device 31 through the second pipeline 42, and the second box body 22 is adapted to supply water to the spraying device 31. The first box body 21 can replenish water to the second box body 22. The spraying device 31 is only connected to the second box body 22, which can simplify the structure.

[0039] Further, in some embodiments of the present utility model, the first box body 21 includes a first water level detector (not shown in the figure), and the first water level detector controls the signal transmission of the control valve 85. The second box body 22 includes a second water level detector, and the second water level detector controls the signal transmission of the control valve 85. The water level detector can be used to judge the water levels in the first box body 21 and the second box body 22. By obtaining the water levels, the opening and closing of the control valve 85 can be controlled according to the water levels. For example, when the water level in the first box body 21 is higher than the set value or the water level in the second box body 22 is lower than the set value, the control valve 85 is closed. Specifically, when the water level in the first box body 21 is lower than the set value and at the same time the water level in the second box body 22 is higher than the set value, the motor 71 is turned on, and the control valve 85 can be automatically opened. The high-pressure water can return to the first box body 21 through the jet nozzle. When the high-pressure water flow passes through the second pipeline 42 of the second box body 22, due to the Bernoulli principle, the water in the second box body 22 is sucked into the first box body 21 until the liquid level in the first box body 21 is higher than the set value or the liquid level in the second box body 22 is lower than the set value, and then the control valve 85 can be automatically closed. Thus, automatic water replenishment from the second box body 22 to the first box body 21 can be realized, which is beneficial to improving the cleaning efficiency, reducing the operation work of the operator, and improving the automation effect.

[0040] In addition, the water level information in the box body can also be fed back to the operator so that the operator can evaluate the cleaning state of the cleaning vehicle 100, thereby reasonably arranging the cleaning work.

[0041] Optionally, it can also be that the first box body 21 communicates with the second box body 22, and the first box body 21 is suitable for supplying water to the spraying device 31. When the water in the first box body 21 is insufficient, the second box body 22 can supply water to the first box body 21 to continuously supply water to the spraying device 31. Or, the second box body 22 is suitable for supplying water to the spraying device 31. When the water in the second box body 22 is insufficient, the first box body 21 can supply water to the second box body 22. It can also be that both the first box body 21 and the second box body 22 can supply water to the spraying device 31. For example, when the water level line in one of the first box body 21 and / or the second box body 22 is lower than the preset value, the other supplies water to the spraying device 31.

[0042] In some embodiments of the present utility model, the height of the second box body 22 relative to the vehicle body 10 is lower than the height of the first box body 21 relative to the horizontal plane, and the spraying device 31 is arranged above the second box body 22. In this way, the space above the second box body 22 can also be utilized to arrange the spraying device 31, so that the spraying device 31 has a certain height. Therefore, the spraying device 31 does not need to be lifted to a relatively high position by a lifting device 50 with a very high lifting height, which is beneficial to reducing the size of the lifting device 50 or simplifying the structure of the lifting device 50, thereby optimizing the structure of the vehicle body 10. For example, the spraying device 31 can be directly arranged above the second box body 22 without arranging the lifting device 50, and the spraying range can be adjusted only by adjusting the spraying device 31; alternatively, the spraying device 31 and the lifting device 50 are arranged above the second box body 22.

[0043] Optionally, it can also be that the first box body 21 has a water inlet, and the second box body 22 has a water outlet. The water inlet and the water outlet are respectively arranged at the bottoms of the first box body 21 and the second box body 22, and the water inlet is communicated with the water outlet. The water in the second box body 22 naturally enters the first box body 21 by gravity.

[0044] Optionally, it can also be that the water in the second box body 22 is sent to the first box body 21 through a pump body.

[0045] Combined with Figure 1 , in some embodiments of the present utility model, the vehicle body 10 includes a front wheel 13 and a rear wheel 14. The second box body 22 is arranged between the front wheel 13 and the rear wheel 14, and at least a part of the first box body 21 is opposite to the rear wheel 14, which can improve the rationality of the gravity distribution of the vehicle body 10 and is beneficial to improving the working stability of the spraying device 31. Specifically, since the size of the second box body 22 may be relatively large and the weight is also relatively large, the second box body 22 can be arranged in the middle of the vehicle body 10 in the front-rear direction, that is, between the front wheel 13 and the rear wheel 14 of the vehicle, which can improve the overall stability of the vehicle body 10. And a spraying device 31 and a lifting device 50 are arranged above the second box body 22. In this way, the spraying device 31 can also be located in the middle of the vehicle body 10, which is beneficial to improving the working stability of the spraying device 31, especially when the spraying device 31 is lifted to a certain height.

[0046] In some embodiments of the present utility model, the vehicle body 10 includes a cab 11 and a chassis 12. The chassis 12 is connected to the cab 11. The first box body 21 and the second box body 22 are arranged on the chassis 12 and fixedly connected to the chassis 12. The second box body 22 is located between the cab 11 and the first box body 21, which is beneficial to improving the structural stability and the compactness of each component on the vehicle body 10, and is convenient for the second box body 22 to supply water to the first box body 21 and the first box body 21 to supply water to the spraying device 31.

[0047] In some embodiments of the present utility model, the spraying device 31 includes a seat body and a spray arm. The spray arm is provided on the seat body and rotates relative to the seat body. The spray arm extends a certain distance in a direction away from the seat body. Thus, the spraying range of the spraying device 31 can be increased, and the cleaning effect can be improved. Optionally, the spraying device 31 can be a hand-held spray gun to facilitate flexible arrangement by the operator.

[0048] In some embodiments of the present utility model, in combination with Figure 1 , the cleaning vehicle 100 further includes a third box body 23. The third box body 23 is provided on a side of the first box body 21 facing away from the second box body 22. A storage space is constructed inside the third box body 23, which can improve the space utilization rate and the functionality of the cleaning vehicle 100.

[0049] In combination with Figure 1 and Figure 2 , in some embodiments of the present utility model, the cleaning vehicle 100 further includes a cleaning device. The cleaning device is connected to the front part of the vehicle body 10 in the front-rear direction. The height of the cleaning device relative to the horizontal plane is lower than the height of the spraying device 31 relative to the horizontal plane. Specifically, the cleaning device is provided in front of the cab 11. The height of the cleaning device is relatively low and can be used to clean or wash the ground. The height of the spraying device 31 is relatively high and can be used for spray dust suppression or spraying maintenance operations on high-altitude facilities such as traffic lights, road signs, and billboards. In addition, the spraying device 31 is arranged at a higher position, and during the process of the water mist falling downward, it can contact the particles in the air, improving the dust suppression effect.

[0050] More specifically, in combination with Figure 1 , the cleaning vehicle 100 may further include a spray gun 34. The spray gun 34 is connected to the first box body 21 and is provided on a side facing away from the spraying device 31, or the spray gun 34 is provided at the rear of the vehicle, so as to achieve spraying and cleaning at the rear of the vehicle. Specifically, the height of the spray gun 34 relative to the horizontal plane can be relatively low, facilitating the operator to hold and operate it, for example, when cleaning a specific area, improving the cleaning effect.

[0051] Combined with the foregoing, a cleaning device is provided at the front of the cleaning vehicle 100, a spraying device 31 is provided in the middle, and a spray gun 34 is provided at the rear. The first box body 21 is provided in the middle of the vehicle, which can facilitate water supply to the cleaning device, the spraying device 31, and the spray gun 34 at the same time. The cleaning device can be used to clean areas with a relatively low position. The spraying device 31 can be adjusted by a lifting device 50 to clean areas with a relatively high position. Thus, the cleaning range of the cleaning vehicle 100 can be increased, and the cleaning effect can be improved. In addition, the cleaning device and the spraying device 31 do not interfere with each other and can be used simultaneously to improve the cleaning efficiency.

[0052] In some embodiments of the present utility model, the cleaning vehicle 100 further includes a fourth box body 24. The fourth box body 24 is disposed on a side of the first box body 21 away from the second box body 22. A power device and a pressure device are provided in the fourth box body 24. The power device is connected to the pressure device and is adapted to provide power for the pressure device. The pressure device is communicated with the first box body 21 to convey the water in the first box body 21 to the spraying device 31. The water in the first box body 21 can be conveyed to the spraying device 31, the cleaning device and the spray gun 34, and the pressure of the water can be increased so that the cleaning device and the spraying device 31 can spray high-pressure water, thereby improving the cleaning effect. In combination with Figure 1 , specifically, the fourth box body 24 is disposed at the rear of the third box body 23, or the fourth box body 24 is disposed at the rear of the vehicle body 10 or on the rear side of the rear wheels 14 of the vehicle body 10.

[0053] In some embodiments of the present utility model, the cleaning device includes a water spraying frame 32 and a nozzle 33. The water spraying frame 32 is connected to the front part of the vehicle body 10. The water spraying frame 32 extends along the left and right directions of the vehicle body 10. The nozzle 33 is disposed on the left or right side of the water spraying frame 32; or the nozzle 33 is movably connected to the water spraying frame 32. Specifically, the water spraying frame 32 is connected to the vehicle body 10, and the nozzle 33 is disposed on the water spraying frame 32. The nozzle 33 can be connected to the vehicle body 10, and the nozzle 33 can move or change its position on the water spraying frame 32, thereby improving the change of the cleaning position and facilitating the improvement of the flexibility during use. Thus, the water spraying frame 32 extends along the left and right directions, and a water spraying effect can be achieved in front of the vehicle. Moreover, the water spraying range extends along the left and right directions. The nozzle 33 is disposed on one side of the water spraying frame 32, and a fixed-point cleaning effect can be achieved.

[0054] The following describes a cleaning vehicle 100 according to a specific embodiment of the present utility model with reference to the accompanying drawings.

[0055] In combination with Figures 1 to 3 , the cleaning vehicle 100 according to an embodiment of the present utility model includes a vehicle body 10, a first box body 21, a second box body 22, a third box body 23, a fourth box body 24, a lifting device 50, a spraying device 31, a cleaning device, a water circuit system and the fourth box body 24.

[0056] Specifically, the water spraying frame 32 is arranged in front of the cab 11 and is fixed to the vehicle body 10 by bolts. The nozzles 33 are arranged at the left front of the water spraying frame 32. The second box body 22 is located in the middle of the vehicle, behind the cab 11 of the vehicle body 10. The lifting device 50 is located above the second box body 22. The spraying device 31 is installed on the lifting device 50. The first box body 21 is located behind the lifting device 50, near the rear axle of the vehicle body 10, and is provided with an overflow pipe and a wave baffle. The third box body 23 is located behind the first box body 21, and tools such as a cleaning cart are placed inside. The fourth box body 24 is located at the rear of the vehicle, and components such as a high-pressure washing reel 61, a high-pressure water pump 62 and a water circuit system, a motor 71 and a transmission mechanism, and a hydraulic power unit 72 are installed in the internal space.

[0057] More specifically, the motor 71 and the transmission mechanism provide power for the high-pressure water pump 62 and the water circuit system. The high-pressure water pump 62 and the water circuit system respectively provide high-pressure water for the cleaning device, the spraying device 31 and the high-pressure washing reel 61. The hydraulic power unit 72 provides hydraulic power for the lifting device 50.

[0058] The second box body 22 is connected to the first box body 21 to increase the water storage capacity of the box body. Specifically, Figure 3 The principle of the high-pressure water circuit is shown. The water spraying frame 32, the nozzles 33, the spraying device 31 and the spray gun 34 can form a linkage water valve group 30.

[0059] Combined with Figure 3 The linkage water valve group 30 is connected to the first box body 21. The first box body 21 includes a first pipeline 41, the second box body 22 includes a second pipeline 42. One end of the first pipeline 41 is connected to the first box body 21, and the other end is connected to the water valve group 30 and the second pipeline 42. The first pipeline 41 includes an automatic unloading valve 80, a pressure gauge 63, a high-pressure water pump 62, a filter 84 and a high-pressure ball valve 64. Thus, the stability of water supply from the first box body 21 to the water valve group 30 can be improved, and the cleaning effect can be enhanced.
