[0048] See also Figures 1 to 6 , this embodiment provides an electric road pollution removal vehicle, including a chassis 1, a cleaning device 2, a first heat preservation box 3 and a heating device 4;

[0049] The chassis 1 is provided with a cleaning device 2, a first heat preservation box 3 and a heating device 4. A battery pack 10 is provided in the first heat preservation box 3. The first heat preservation box 3 is provided with a first connection port and a first vent. The first connection port serves as a connection channel between the battery pack 10 and an external electrical device, wherein the electrical device includes a motor for driving the chassis 1 to move.

[0050] The heating device 4 includes a heater and a hot air duct. The heater is arranged on the chassis 1 and is connected to the first vent through the hot air duct to heat up the battery pack 10 in the first insulation box 3 .

[0051] The battery pack 10 on the electric road pollution removal vehicle plays a vital role. It is the energy heart of the entire vehicle, responsible for storing and releasing electrical energy on demand to drive various functional components of the vehicle, ensuring that the vehicle can perform cleaning tasks efficiently and environmentally friendly. Specifically, the functions of the battery pack 10 mainly include:

[0052] 1. Powering the drive motor: The most direct and critical function of the battery pack 10 is to provide power to the motor so that the vehicle can travel. In an electric sanitation vehicle, the high-power drive motor relies on the electrical energy released by the battery pack 10 to convert into mechanical energy to propel the vehicle forward, backward, and perform various operations such as acceleration and steering.

[0053] 2. Support auxiliary systems: In addition to the drive motor, the electric road pollution removal vehicle is also equipped with a variety of auxiliary systems, such as a cleaning device 2, a water pump (for water spraying and recycling systems), a control system, a lighting system, etc. These auxiliary systems also require electrical energy to maintain operation. The battery pack 10 provides the necessary power support for these components to ensure that the various parts of the vehicle operate in coordination when performing cleaning tasks.

[0054] The first thermal insulation box 3 is made of insulating material and is tightly mounted on the chassis 1. The core of the vehicle, the battery pack 10, is safely contained inside. In order to facilitate the electrical connection between the battery pack 10 and other systems of the vehicle, the thermal insulation box is specially provided with a first connection port with good sealing performance. A sealing member (such as a sealing ring or a sponge) can be provided at the first connection port to ensure that the battery pack 10 can stably supply power to electrical devices such as motors while maintaining the heat preservation effect.

[0055] The heater is installed at an appropriate position of the chassis 1 and can generate warm airflow. The warm air is directly introduced into the first insulation box 3 through the hot air duct, effectively surrounding and heating the battery pack 10.

[0056] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 In this embodiment, the first heater 41 may be a fuel heater, and the first heater 41 is connected to a fuel tank 45, which provides the fuel required for the operation of the first heater 41. By maintaining the battery pack 10 in a suitable operating temperature range, generally making the ambient temperature of the first insulation box 3 and the battery pack 10 greater than zero degrees Celsius, the chemical reaction rate of the battery and the energy loss are effectively slowed down, thereby significantly extending the overall service life of the battery and reducing long-term operating costs.

[0057] In some embodiments, the heater is an electric heater, which can be powered by the battery pack 10. Hot air heating does not involve the emission of harmful substances and does not create the risk of liquid leakage, so it is relatively safe.

[0058] See also Figure 3 In this embodiment, the electric road pollution removal vehicle further includes a temperature sensor 110 and a controller. The temperature sensor is arranged in the first heat preservation box 3, located on one side of the battery pack 10. The temperature sensor 110 is used to detect the temperature in the first heat preservation box 3. The chassis 1 is provided with a cab, and the cab is provided with a display screen. The display screen and the temperature sensor 110 are respectively connected to the controller, and the controller is used to receive the temperature information detected by the temperature sensor 110 and display it through the display screen. This makes it convenient for the electric road pollution removal vehicle to keep the battery pack 10 in a zero-temperature environment when operating in winter.

[0059] One or more high-precision temperature sensors are installed inside the first insulated box 3 near the battery pack 10. These sensors are exquisitely designed and can accurately sense the real-time temperature changes inside the insulated box, especially around the battery pack 10. The controller establishes a communication connection with the temperature sensor and the display screen in the cab by wired or wireless means. The controller has data processing and logic judgment functions and can be installed in the chassis 1 or the car. A clear and readable display screen is set in the cab, which not only displays the basic operating information of the vehicle, but also displays the internal temperature data of the insulated box transmitted by the temperature sensor in real time. The temperature sensor continuously monitors the temperature inside the insulated box and sends the data to the controller; after the controller processes the data, it immediately transmits the current temperature value to the display screen in the cab for display, so that the driver can understand the ambient temperature of the battery pack 10 at any time to avoid freezing due to low temperature.

[0060] In this embodiment, the controller is connected to the heaters (the first heater 41, the second heater 43, and the third heater) to control the operation of the heaters. If the temperature in the first insulated box 3 is lower than a preset threshold, the controller can further trigger the heater, automatically adjust the working state of the heater, and increase the wind speed to increase the temperature in the insulated box, thereby ensuring that the battery pack 10 is in an ideal operating environment.

[0061] See also Figure 3 In this embodiment, waterproof thermal insulation cotton 120 is attached to the inner wall of the first thermal insulation box 3 or the outer wall of the battery pack 10. The waterproof thermal insulation cotton 120 can be attached to the inner wall of the first thermal insulation box 3, close to the battery pack 10, to form a thermal insulation layer; or it can be directly wrapped on the outer wall of the battery pack 10 to form a thermal insulation shell close to the battery. In practical applications, the attachment position may be flexibly selected according to the design of the thermal insulation box and the layout of the battery pack 10, or the two may be used in combination. Preferably, the waterproof thermal insulation cotton 120 can be attached to the inner wall of the first thermal insulation box 3 without wrapping the outer wall of the battery pack 10. The thermal insulation cotton is firmly fixed in a predetermined position with an adhesive to ensure that it will not fall off or shift during the operation of the vehicle. The attachment of the waterproof thermal insulation cotton 120, through its low thermal conductivity and high-density structure, effectively reduces the heat loss through the thermal insulation box wall or directly from the surface of the battery pack 10, especially in cold and humid environments, which can significantly slow down the temperature drop of the battery. At the same time, its waterproof properties prevent external moisture from penetrating, protecting the battery from moisture erosion and avoiding battery performance degradation or safety hazards caused by humidity.

[0062] See also Figure 1 , Figure 3 and Figure 6In this embodiment, the electric road pollution removal vehicle further includes a clean water tank 9, a water supply device 7, a second heat preservation box 5 and a third heat preservation box 6; the water supply device 7 includes a high-pressure water pump 71, a water supply pipe and a filter 77, the clean water tank 9, the high-pressure water pump 71 and the cleaning device 2 are connected through a water supply pipe, the filter 77 is connected in series to the water supply pipe between the water inlet of the high-pressure water pump 71 and the clean water tank 9, the filter 77 is provided with a second heat preservation box 5 outside the filter 77, the second heat preservation box 5 is provided with a second vent and a second connection port for accommodating the water supply pipe, the high-pressure water pump 71 is provided with a third heat preservation box 6 outside the high-pressure water pump 71, the third heat preservation box 6 is provided with a third vent and a third connection port for accommodating the water supply pipe; the heater includes a first heater 41 and a second heater 43, the hot air pipe includes a first hot air pipe 42 and a second hot air pipe 44, the first heater 41 is connected to the first vent through the first hot air pipe 42, and the second heater 43 is connected to the second vent and the third vent through the second hot air pipe 44.

[0063] The clean water tank 9 is the main water source for vehicle cleaning operations. The clean water tank 9 stores sufficient clean water for the high-pressure water pump 71 to extract and use. The high-pressure water pump 71 draws water from the clean water tank 9 through the low-pressure pipe 76, and after purification by the filter 77, it is output through the high-pressure water pump 71 and the high-pressure pipe 72. The high-pressure pipe 72 can be connected to the cleaning device 2 to clean the road in the form of high-pressure water jets.

[0064] The second insulation box 5 is arranged around the filter 77, and the third insulation box 6 wraps the high-pressure water pump 71. Both insulation boxes are made of insulation materials and are sealed. The inner wall can also be attached with waterproof insulation cotton, and each is provided with a vent and a connection port to facilitate the passage of the pipeline and the circulation of hot air. Since the filter 77 and the high-pressure water pump 71 are placed in a similar position, the first heater 41 provides warm airflow to the first insulation box 3 (i.e., the insulation box where the battery pack 10 is located) through the first hot air duct 42, and the second heater 43 provides warm airflow to the second insulation box 5 (surrounding the filter 77) and the third insulation box 6 (wrapping the high-pressure water pump 71) through the second hot air duct 44, ensuring that the temperature of these key components is maintained within the ideal working range. Among them, the second hot air duct 44 has two air outlets, which are connected to the second vent and the third vent respectively.

[0065] See also Figure 4 In this embodiment, the structure of the second heater 43 is the same as that of the first heater 41. When the first heater 41 is a fuel heater, the second heater 43 is also a fuel heater, and the oil tank 45 is connected to the first heater 41 and the second heater 43 respectively.

[0066] See also Figure 1In this embodiment, the electric road pollution removal vehicle also includes a carriage, which is arranged on the upper surface of the chassis 1, and a first insulation box 3 is provided in the carriage. A first vent is provided at the bottom of the first insulation box 3.

[0067] See also Figure 1 , Figure 5 and Figure 6 In this embodiment, the electric road pollution removal vehicle further includes a clean water tank 9, a water supply device 7 and an antifreeze device 8; the water supply device 7 includes a high-pressure water pump 71, a water supply pipeline and a filter 77, the water supply pipeline includes a low-pressure pipeline 76 and a high-pressure pipeline 72, the water inlet of the high-pressure water pump 71 is connected to the clean water tank 9 through the low-pressure pipeline 76, the filter 77 is connected in series with the low-pressure pipeline 76, and the water outlet of the high-pressure water pump 71 is connected to the high-pressure pipeline 72; the antifreeze device 8 includes an antifreeze tank 81, an antifreeze recovery pipe 82 and a reversing valve 83, the water outlet of the high-pressure water pump 71 is connected to the high-pressure pipeline 72 through the reversing valve 83, and the reversing valve 83 is connected to the antifreeze tank 81 through the antifreeze recovery pipe 82, for recovering the antifreeze in the water supply pipeline. The antifreeze can be, but is not limited to, an antifreeze containing ethylene glycol, an antifreeze containing propylene glycol, or an antifreeze containing diethylene glycol.

[0068] The reversing valve 83 is installed between the water outlet of the high-pressure water pump 71 and the high-pressure pipe 72, and can switch between water supply and recovery modes. When no operation is required or the vehicle is parked at low temperature, the reversing valve 83 switches to the recovery mode, and the antifreeze recovery pipe 82 in the high-pressure pipe 72 flows back to the antifreeze tank 81, where the antifreeze is mixed with water to prevent the pipe from freezing. In the water supply mode, the connection between the reversing valve 83 and the antifreeze recovery pipe 82 is cut off.

[0072] In this embodiment, the outside of the high-pressure pipeline 72 and the low-pressure pipeline 76 are both provided with heating belts and insulation layers. All pipelines except the second insulation box 5 and the third insulation box 6 are wrapped with heating belts and insulation layers to ensure the normal flow of water in the pipeline. The heating belt uses an electric heating element, which can be powered by the battery pack 10 of the vehicle. The power output of the heating belt is adjusted by the intelligent control system to maintain the fluid in the pipeline within the ideal temperature range. The outside of the heating belt is wrapped with a layer of high-efficiency insulation material to form an insulation layer.

It should be noted that the cleaning device 2 is a prior art, and its specific structure can refer to the patent CN211815905U.

[0075] In this embodiment, the clean water tank 9 and the dirty water tank can form a storage bin, which is located on the upper surface of the chassis 1.

[0076] In this embodiment, a corresponding temperature sensor is installed in the clean water tank 9 to monitor and prevent freezing due to excessively low temperature.

[0077] See also Figure 1In this embodiment, the chassis 1 includes a frame 11 that supports the carriage, the cleaning device 2, the first bracket 13, the second bracket 14, the bracket 12, the water supply pipe and other components. The frame 11 is usually made of high-strength steel or aluminum alloy to achieve the dual goals of light weight and high strength. The frame 11 is also provided with a special area to accommodate the motor, transmission mechanism and wiring harness. The controller connects various components through the wiring harness and is responsible for collecting data, processing information and controlling the coordinated work of various parts of the vehicle.

[0078] The operating process of the electric road pollution removal vehicle is;

[0079] The first heater 41 of the heating device 4 must be turned on first to make the ambient temperature of the first insulation box 3 greater than zero degrees to avoid a significant attenuation of the battery; the second heater 43 of the heating device 4 must be turned on first to make the ambient temperature of the second insulation box 5 and the third insulation box 6 greater than zero degrees to ensure their normal functions; the heating belt must be turned on first to ensure that the temperature outside the pipeline is greater than zero degrees, and the temperature of the outside is maintained by insulation cotton.

[0080] Open the winter ball valve 74 of the pure electric all-weather road pollution removal, switch to the winter operation mode, start the high-pressure water pump 71, and the water in the clean water tank 9 is sucked out from the water outlet, passes through the filter 77 and other parts, enters the high-pressure water pump 71, and is pressurized and sprayed to the high-pressure water pipe, and then passes through the reversing valve 83, and finally sprayed to the road surface by the nozzle of the cleaning device 2. At the same time, start the fan 22 to generate super large air volume and negative pressure, and the sewage is sucked from the suction port of the suction seat 21 of the cleaning device 2 and enters the sewage tank, and the gas is discharged after filtering.

[0081] After the operation is completed, the water channel is automatically drained, antifreeze is automatically added, and the heating device 4 is turned off until the next day's operation. The reversing valve 83 is switched, the high-pressure water pipe is connected to the antifreeze return pipe, and the high-pressure water pump 71 is turned on. The antifreeze is recovered to the antifreeze tank 81 through the pre-set time, and the reversing valve 83 automatically returns to its position to avoid antifreeze contaminating the road environment and wasting antifreeze, thereby reducing operating costs.

[0082] It has the following beneficial effects:

[0083] (1) It can operate around the clock, solving the problem of no equipment operation in winter.

[0084] (2) The heating device 4 increases the ambient temperature of the battery pack 10, thereby reducing battery attenuation and increasing operating endurance.

[0085] (3) According to different working conditions, the working environment temperature of each situation can be monitored in real time to avoid abnormalities.

[0086] (4) You can choose winter mode or summer operation mode. Selecting winter operation mode solves the problem of auxiliary water tank antifreeze.
