Description

Technical Field

[0001] The present invention relates to the technical field of sanitation vehicles, and particularly to a washing and sweeping vehicle. The present invention also relates to a control method for controlling the above-mentioned washing and sweeping vehicle. Background Art

[0002] At present, with the rapid advancement of urbanization, the urban scale continues to expand, the road network continues to extend, and the task of urban road cleaning and sanitation becomes increasingly onerous. The traditional manual cleaning mode is not only extremely inefficient and unable to cope with large-area and long-distance road cleaning work, but also faces huge challenges in terms of economy as the labor cost increases year by year.

[0003] Urban road structures are diverse. Taking urban expressways as an example, they usually have a main road and a service road. In the traffic environment of the main road, vehicles travel at high speeds. To prevent traffic congestion or even traffic accidents caused by road cleaning operations, there are high requirements for the operation speed of sanitation cleaning vehicles, which need to be able to achieve fast and efficient operations. The situation of the loop service road is more complex, with a rich variety of traffic participants. Sanitation operation vehicles are mostly vehicles with large loads. When operating in such a complex road environment, for safety reasons, the operation speed has to be controlled.

[0004] The existing washing and sweeping vehicles expose obvious drawbacks in the face of such diverse urban road cleaning requirements. In the scenario of cleaning the main road where fast operation is required, its operation speed is difficult to increase, resulting in low cleaning efficiency and unable to meet the requirements of the expressway traffic conditions for the timeliness of cleaning operations; in complex road conditions such as loop service roads, even if the speed needs to be controlled due to safety factors, there is not enough room for optimizing its own operation speed, making it difficult to improve the operation efficiency while ensuring safety, which is not conducive to improving the use quality of the washing and sweeping vehicle.

[0065] To better protect the structure of the collection part 5, a protective structure is provided at the top of the collection part 5 of the road sweeper in this embodiment. The protective structure covers the upper part of the connection between the first adsorption part 202 and the second adsorption part 302 and the collection part 5. Through the setting of the protective structure, covering the top of the collection part 5 helps to block the garbage inhaled into the collection part 5 from directly hitting the top of the collection part 5, which is beneficial to protecting the collection part 5 and helps with the design implementation.

[0066] Specifically, the protective structure includes a rectangular reinforcing plate provided at the top of the collection part 5, and four trapezoidal reinforcing side plates connected to the four sides of the rectangular reinforcing plate and inclined downward from the top of the collection part 5. When the garbage enters the collection part 5 through the first extension pipe 2041 or the second extension pipe 3041, it will impact on the reinforcing plate and the reinforcing side plates to prevent the garbage from directly hitting the top of the collection part 5.

[0067] The road sweeper of this embodiment can quickly clean the garbage on the ground and wash and sweep the ground. Through the cooperation of the first cleaning mechanism 2, the second cleaning mechanism 3, the high-pressure waterway system 4, the collection part 5 and the negative pressure device 6 provided on the vehicle chassis 1, it can quickly wash and sweep the garbage on the ground, which is beneficial to improving the working efficiency of the road sweeper and helps to improve the use quality of the road sweeper.

[0068] Embodiment Two

[0069] This embodiment relates to a control method for a road sweeper, and this control method is used to control the road sweeper in Embodiment One.

[0070] The control method of the road sweeper in this embodiment includes a normal mode, an energy-saving mode and a strong mode. After judging the road conditions, the operator can select different modes to control the road sweeper to clean the road surface.

[0071] In the normal mode, the first cleaning mechanism 2 is controlled to work according to the first preset parameters, so that the first spraying assembly 201 sprays and washes the ground, and the first adsorption part 202 sucks up the sundries on the ground.

[0072] Among them, the first preset parameters include the water pressure output by the high-pressure waterway system 4 and the air volume of the negative pressure device 6. In this embodiment, the water pressure and air volume of the first preset parameters can be, for example, a water pressure of 5 MPa and an air volume of 7300 m 3 / h. The normal mode can be applied, for example, to the situation where there are large debris on the ground. By adopting the normal mode, only the first cleaning mechanism 2 is put into use, which is conducive to collecting and cleaning the large debris on the ground and washing the ground.

[0073] In the energy-saving mode, the second cleaning mechanism 3 is controlled to operate according to the second preset parameters, so that the second spraying component 301 sprays and washes the ground, and the second adsorption part 302 sucks up the ground debris.

[0074] Among them, the second preset parameters include the water pressure output by the high-pressure water circuit system 4 and the air volume of the negative pressure device 6. In this embodiment, the water pressure and air volume of the second preset parameters can be, for example, a water pressure of 3 MPa and an air volume of 8500 m 3 / h. The energy-saving mode can be applied, for example, to the situation where the ground is relatively clean and only granular debris exists. By adopting the energy-saving mode, it is conducive to only putting the second cleaning mechanism 3 into use when the ground is relatively clean. The second cleaning mechanism 3 sucks up the particulate matter on the ground and washes the ground to meet the energy-saving use situation on a relatively clean road surface.

[0075] In the strong mode, the first cleaning mechanism 2 and the second cleaning mechanism 3 are controlled to operate according to the third preset parameters, so that the first spraying component 201 and the second spraying component 301 jointly spray and wash the ground, and the first adsorption part 202 and the second adsorption part 302 jointly suck up the ground debris.

[0076] Among them, the third preset parameters include the water pressure output by the high-pressure water circuit system 4 and the air volume of the negative pressure device 6. In this embodiment, the water pressure and air volume of the third preset parameters can be, for example, a water pressure of 4 MPa for the first spraying component 201, a water pressure of 2 MPa for the second spraying component 301, and an air volume of 11500 m 3 / h. The strong mode can be applied, for example, to the situation where rapid cleaning is required. When performing strong-mode washing and sweeping, by making the water pressure of the first spraying component 201 greater than the water pressure of the second spraying component 301 and increasing the air volume, the water traces remaining on the ground after the washing and sweeping vehicle passes can be reduced, which helps to quickly dry the road surface and is conducive to use in the situation where rapid cleaning is required.

[0077] The control method of the washing and sweeping vehicle in this embodiment forms a normal mode, an energy-saving mode, and a strong mode. The operator can control the washing and sweeping vehicle in Embodiment 1 to work in different modes according to the control method of the washing and sweeping vehicle in this embodiment, which can quickly clean the garbage on the ground and wash and sweep the ground. Through the cooperation of the first cleaning mechanism 2, the second cleaning mechanism 3, the high-pressure water circuit system 4, the collection part 5, and the negative pressure device 6 provided on the vehicle chassis 1, the garbage on the ground can be quickly washed and swept, which is conducive to improving the working efficiency of the washing and sweeping vehicle and helps to improve the use quality of the washing and sweeping vehicle.

[0078] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
