Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a water system, control method, sweeper truck, and storage medium for a sweeper truck. Background Technology

[0002] With the advancement of technology and the continuous development of society, more and more people have realized the importance of environmental protection. Generally, multi-functional sanitation vehicles (such as sweeper trucks) with functions such as road sweeping, washing, and vacuuming are used to clean the roads.

[0003] like Figure 1 As shown, current sweeper trucks all use a centrally located wide suction nozzle arrangement. The suction nozzle includes left and right high-pressure spray bars and a high-pressure spray bar built into the middle of the nozzle. The spray bar has several fan-shaped nozzles. The high-pressure fan-shaped water jets formed by the jets from the fan-shaped nozzles overlap and combine to form a V-shaped high-pressure water jet, which strips and drives the dirt on the road surface into the suction nozzle. Then, the negative pressure of the centrifugal fan is used to collect it back into the garbage bin. Because the high-pressure water system is driven by only one water pump, the pressure in the high-pressure water pipeline is roughly the same, which easily creates watermarks when spraying water, resulting in poor road cleaning and sweeping effects. Summary of the Invention

[0004] This application provides a water system, control method, sweeper, and storage medium for a sweeper, to solve the problems in related technologies where the water pressure between each group of spray bars is basically the same, which easily forms watermarks when spraying water, resulting in poor sweeping and cleaning effects.

The method is used in the water system of the sweeper truck as described in any of the above embodiments, including: detecting the sweeping operation state of the sweeper truck; when the sweeping operation state is that the sweeper truck is working, adjusting the water spray pressure of a target spray bar among the plurality of spray bars, and detecting the water spray pressure of the target spray bar and the water spray pressure of other spray bars; and completing the water spray pressure adjustment when the water spray pressure of the target spray bar and the water spray pressure of other spray bars both reach their respective target pressures, so that the target spray bar and the other spray bars work under different water spray pressures.

[0011] Optionally, adjusting the water pressure of the target spray bar among the plurality of spray bars includes: controlling the opening of the first throttle valve to the maximum and closing the second throttle valve, so that the water pressure of the other spray bars and the water pressure of the target spray bar both reach a first target pressure; controlling the first throttle valve to adjust the inlet flow rate of the water supply line of the target spray bar until the water pressure of the other spray bars shows an increasing trend and the water pressure of the target spray bar shows a decreasing trend, and maintaining the opening of the first throttle valve; controlling the second throttle valve to adjust the return flow rate of the target spray bar until the water pressure of the target spray bar reaches a second target pressure, and maintaining the opening of the second throttle valve.

[0012] Optionally, the first target pressure is greater than the second target pressure.

[0013] Optionally, after making the target spray bar work under different water pressures as the other spray bars, the method further includes: obtaining the optimal vehicle speed of the sweeper truck when spraying water; and controlling the sweeper truck to spray water at the optimal vehicle speed.

By controlling the target spray bar to spray water at different pressures compared to other spray bars, the formation of comb-like watermarks can be avoided, effectively improving the cleaning and sweeping effect. This solves the problems in related technologies where the water pressure of each group of spray bars is basically the same, easily forming watermarks during spraying and resulting in poor cleaning and sweeping effects.

[0024] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0025] The following description, with reference to the accompanying drawings, outlines the water system, control method, sweeper, and storage medium of an embodiment of this application. Addressing the problems mentioned in the background section, this application provides a water system for a sweeper. By adding two throttle valves to adjust the water pressure of a target spray bar among multiple spray bars, each group of spray bars can operate simultaneously at different pressures with only one water pump. By controlling the target spray bar to spray water at different pressures compared to other spray bars, the formation of comb-like watermarks can be avoided, effectively improving the sweeping and cleaning effect. This solves the problem in related technologies where the water pressure between different groups of spray bars is essentially the same, easily forming watermarks during spraying and resulting in poor sweeping and cleaning effects.

[0026] Specifically, Figure 2 A block diagram of the water system of the sweeper truck according to an embodiment of this application.

[0027] like Figure 2 The water system 10 of the sweeper truck includes: a water tank 100, a water pump 200, a multi-channel water supply assembly 300, multiple spray booms, a first throttle valve 400, a second throttle valve 500, a first pressure gauge 600, and a second pressure gauge 700.

[0028] The water pump 200 has its inlet connected to the water tank 100 via a first pipe. The inlet of the multi-channel water supply assembly 300 is connected to the outlet of the water pump 200 via a second pipe. The multiple outlets of the multi-channel water supply assembly 300 are connected to multiple spray bars, and one of the outlets is connected to the water tank 100 via a third pipe. A first pressure gauge 600 is installed on the second pipe to detect the water spray pressure of the multiple spray bars. A second pressure gauge 700 is installed on the target spray bar to detect its water spray pressure. A first throttle valve 400 is installed on the target spray bar, and the outlet of the target spray bar near the first throttle valve 400 is connected to the third pipe via a fourth pipe. A second throttle valve 500 is installed on the fourth pipe. The water spray pressure of the target spray bar is adjusted by the first throttle valve 400 and the second throttle valve 500, allowing the target spray bar to operate at different water spray pressures than the other spray bars.

[0029] The sweeper in this embodiment includes multiple spray bars, each with several fan-shaped nozzles, such as... Figure 3 As shown, the high-pressure fan-shaped water jet formed by the fan-shaped nozzle has a greater impact force in the middle and a smaller impact force on both sides. The higher the water pressure, the more obvious the effect.

[0030] like Figure 3Taking the target spray boom shown as an example, it consists of more than 10 nozzles. The black overlapping part of the fan-shaped water jet has a weaker impact force, while the non-overlapping part in the middle has a stronger impact force. This creates a difference in the strength of the impact force on the ground, resulting in water streaks on the washed surface. Experiments have shown that the lower the system pressure, the smaller the pressure difference between the middle part and the sides of the nozzle, the weaker the impact force on the road surface, and the less noticeable the water streaks after the operation. However, a lower impact force will result in a poorer cleaning effect on the road surface, especially for other spray booms, which are higher off the ground, and the curbs on both sides of the road are relatively dirty areas, requiring higher impact force from the nozzles.

[0031] Therefore, during the operation of the sweeper truck, this embodiment of the application, while ensuring the water spray pressure of other spray bars, needs to reduce the water pressure in the target spray bar. This is achieved by adjusting the water spray pressure of the target spray bar among multiple spray bars using the first throttle valve 400 and the second throttle valve 500, until the water spray pressure of the target spray bar and the water spray pressure of other spray bars all reach their respective target pressures. This completes the water pressure adjustment, allowing each group of spray bars to operate simultaneously under different pressures. This ensures the cleanliness and sweeping effect of the road surface, reduces the impact of comb-like watermarks on the road surface, and increases the adaptability of the sweeper truck to different road conditions such as urban roads, national highways, and suburban areas. Simultaneously, this embodiment of the application uses a water pump 200 to deliver water from the water tank 100 to each spray bar, while excess water flows back to the water tank 100 through the second throttle valve 500. This extends the operating time of the sweeper truck and improves its operating efficiency.

[0032] For example, other spray booms in the water system 10 of the sweeper vehicle in this application embodiment, such as... Figure 4 The left and right spray booms shown are examples of target spray booms. Figure 4 The center spray bar shown has a first throttle valve 400. Figure 4 The throttle valve I and the second throttle valve 500 shown are as follows: Figure 4 The throttle valve II shown is located on the fourth pipeline, while throttle valve I is mounted on the central spray bar. The first pressure gauge 600... Figure 4 The pressure gauge shown is I, and the second pressure gauge is 700, for example. Figure 4 The pressure gauge shown is II. Pressure gauge I is used to detect the water spray pressure of the left and right spray bars, and pressure gauge II is used to detect the water spray pressure of the middle spray bar.

[0033] Furthermore, such as Figure 4 As shown, the water system 10 of the sweeper truck in this embodiment of the application also includes a ball valve and a filter installed on the first pipeline. The filter can ensure the safety of the water quality flowing into the water pump, improve the service life of the water pump, and effectively prevent the nozzles installed on the outlet branch pipe from becoming clogged.

[0034] Furthermore, such as Figure 4As shown, in this embodiment, the outlet side of the second pipeline near the water pump 200 is connected to the water tank 100 via a fifth pipeline; a pressure regulating valve is installed on the fifth pipeline to regulate the water supply pressure of the second pipeline. When water flows through the pressure regulating valve, the valve is subjected to the pressure of the water flow, thereby generating a reaction force that closes the valve. The spring inside the pressure regulating valve generates an upward force, opening the valve. When the fluid pressure exceeds a set value, the pressure regulating valve is pushed closed by the pressure, thereby reducing the flow rate and lowering the pressure. Conversely, when the water pressure is lower than the set value, the pressure regulating valve is pushed open by the spring, increasing the flow rate and raising the pressure.

[0035] Furthermore, such as Figure 4 As shown, the outlet side of the second pipeline near the water pump 200 is connected to the water tank 100 via a sixth pipeline. An unloading valve is installed on the sixth pipeline to maintain the water supply pressure of the second pipeline. When water flows through the unloading valve, the valve experiences a certain pressure, causing it to close. When the pressure reaches a certain level, the unloading valve opens, thus maintaining the flow rate and pressure at a certain level. This also prevents the system from experiencing excessive pressure, which could damage other valves or compromise the safety of the entire system.

[0036] The water system of the sweeper truck proposed in this application's embodiments adjusts the water spray pressure of the target spray bar among multiple spray bars by adding two throttle valves. This allows each group of spray bars to operate simultaneously at different pressures with only one water pump. By controlling the target spray bar to spray water at different pressures compared to other spray bars, the formation of comb-like watermarks can be avoided, effectively improving the sweeping and cleaning effect. This solves the problems in related technologies where the water pressure of each group of spray bars is basically the same, easily forming watermarks during spraying and resulting in poor sweeping and cleaning effects.

[0037] Next, referring to the accompanying drawings, a water pressure control method for a sweeper truck according to an embodiment of this application is described. This method is used in the water system of the sweeper truck in the above embodiment.

[0038] Figure 5 This is a flowchart illustrating a control method for the water system of a sweeper truck provided in an embodiment of this application.

[0039] like Figure 5 As shown, the water pressure control method of this sweeper truck includes the following steps:

[0040] In step S501, the cleaning status of the sweeper is detected.

[0041] In step S502, when the sweeping operation is in the working state of the sweeper truck, the water spray pressure of the target spray bar among the multiple spray bars is adjusted, and the water spray pressure of the target spray bar and the water spray pressure of other spray bars are detected.

[0042] In one embodiment of this application, adjusting the water pressure of a target spray bar among multiple spray bars includes: controlling the opening of a first throttle valve to its maximum and closing a second throttle valve, so that the water pressure of the other spray bars and the water pressure of the target spray bar both reach a first target pressure; controlling the first throttle valve to adjust the inlet flow rate of the water supply line of the target spray bar until the water pressure of the other spray bars shows an increasing trend and the water pressure of the target spray bar shows a decreasing trend, and maintaining the opening of the first throttle valve; controlling the second throttle valve to adjust the return flow rate of the target spray bar until the water pressure of the target spray bar reaches a second target pressure, and maintaining the opening of the second throttle valve.

[0043] The first target pressure is greater than the second target pressure. Both the first and second target pressures can be specifically set or calibrated according to the sweeper's operating mode and the vehicle's current speed, without specific limitations.

[0044] Specifically, the implementation of this application can be combined with, for example, Figure 4 The water system of the sweeper truck is described in detail below. This embodiment adds two throttle valves, namely throttle valve I and throttle valve II. During adjustment, the system pressure is adjusted first, followed by the pressure of the central spray boom. Therefore, in this embodiment, throttle valve II can be closed first, while throttle valve I is fully open. Taking the sweeper truck in standard operating mode as an example, the system pressure displayed by pressure gauges I and II is the first target pressure A (MPa). To ensure cleaning effectiveness and reduce road surface streaks, this embodiment can gradually reduce the diameter of throttle valve I by adjusting the opening of the throttle valve until the reading of pressure gauge I shows a trend greater than A (MPa). At this point, throttle valve I is no longer adjusted, and the flow rate through throttle valve I remains constant, so the pressure A (MPa) of pressure gauges I and II remains unchanged. Then, throttle valve II is opened and adjusted, and the reading of pressure gauge II is observed to gradually decrease until the second target pressure B (MPa) is reached. At this point, throttle valve II is no longer adjusted, thus achieving operation of the central spray boom at pressure B (MPa); the side spray booms continue to operate at pressure A (MPa). The same principle can be applied to the third or even more spray booms, allowing each boom to operate at a different pressure. By using only one water pump, each spray boom can operate simultaneously at different pressures, improving the cleaning effect and ensuring that comb marks are largely removed after the cleaning process.

[0045] Furthermore, the pressure of the side spray bar A can also be adjusted. If the reading of the system throttle valve I is adjusted further and C > A (MPa), it can handle the condition where the outer curb of the vehicle is relatively dirty.

[0046] In this embodiment, the adjustment of the first and second throttle valves can be done manually or electrically. For example, in the case of manual adjustment, the operator can determine whether the readings of pressure gauge I and pressure gauge II show an increasing or decreasing trend. In the case of electrical control adjustment, the readings of pressure gauge I and pressure gauge II can be acquired by an image acquisition device (such as a camera), and the increasing or decreasing trend of pressure gauge I and pressure gauge II can be identified by a computer algorithm, without specific limitations.

[0047] In step S503, the water pressure adjustment is completed when the water pressure of the target spray bar and the water pressure of the other spray bars both reach their respective target pressures, so that the target spray bar and the other spray bars work under different water pressures.

[0048] This application embodiment can control the target spray bar and other spray bars to spray water at different pressures, which can avoid the formation of comb-like watermarks and effectively improve the cleaning effect.

[0049] In one embodiment of this application, after the target spray bar and other spray bars are made to work under different water spray pressures, the method further includes: obtaining the optimal vehicle speed when the sweeper sprays water; and controlling the sweeper to spray water at the optimal vehicle speed.

[0050] It is understandable that vehicle speed also affects the cleaning effect of the road surface. If the vehicle speed is too high, the road surface will not be cleaned properly, while if the vehicle speed is too low, water resources will be wasted. Therefore, the embodiments of this application must ensure both the pressure of each group of spray bars of the sweeper and the speed of the sweeper during operation. For example, after testing, it was verified that at a vehicle speed of about 8 km / h, the target spray bar has the best effect at a pressure of B (MPa), while other spray bars have better effects at a pressure of ≥A (MPa).

[0051] When the sweeper truck is working, the embodiments of this application can determine the optimal speed of the target spray bar and other spray bars under different spray pressures by querying the relationship table between water spray pressure and optimal vehicle speed. By controlling the sweeper truck to spray water at the optimal speed, the sweeper truck can achieve good cleaning quality and work efficiency.

[0052] According to the control method of the water system of the sweeper truck proposed in this application, when the sweeper truck is working, the water spray pressure of the target spray bar among multiple spray bars is adjusted. The water spray pressure adjustment is completed when the water spray pressure of the target spray bar and the water spray pressure of other spray bars all reach their respective target pressures. This allows each group of spray bars to work simultaneously under different pressures, thus ensuring the cleanliness and sweeping effect of the road surface while reducing the impact of watermarks left by the spray bar on the road surface. Therefore, this solves the problems in related technologies where the water pressure of each group of spray bars is basically the same, which easily forms watermarks during spraying, resulting in poor sweeping effect.
