[0017] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use. Example

[0018] A high-pressure water circuit antifreeze drainage system for a vacuum cleaning truck, such as Figures 1-3 As shown, the system includes a chassis power take-off system 1, a high-pressure water circuit system 5, a fan system 2, an air vortex tube device 3, and a temperature control system 4. The chassis power take-off system 1 provides power to the fan system 2 and the high-pressure water circuit system 5. The air outlet of the fan system 2 is connected to the air vortex tube device 3. The temperature control system 4 is connected to the fan system 2 and the air vortex tube device 3. The air vortex tube device 3 separates the hot and cold air of the fan system 2. The temperature control system 4 detects the outdoor temperature and controls the drainage status of the system according to the outdoor temperature to achieve antifreeze drainage and reduce water waste. The air vortex tube device 3 separates the hot and cold water discharged from the drainage system. High-temperature air is input into the high-pressure water circuit system 5 for antifreeze drainage, and low-temperature air is input into the fan system 2 for fan-side air supply and fan heat dissipation.

[0019] The chassis power take-off system 1 includes an engine connected to a gearbox, which is connected to an auxiliary hydraulic pump, a rear axle, and two output transfer cases. The two output transfer cases are respectively connected to the blower system 2 and the high-pressure water circuit system 5. The blower system 2 and the high-pressure water circuit system 5 are powered by the engine and gearbox. The auxiliary hydraulic pump drives the tank of the cleaning vacuum truck to lift, the rear door to open and lock, and the reel to rotate and swing.

[0020] The high-pressure water system 5 includes a clean water tank, a high-pressure pump, a water filter, a three-way ball valve, a high-pressure reel, and a nozzle. The clean water tank is connected to the air vortex tube device 3 via an inlet pipe. The clean water tank is connected to the high-pressure pump, and the input end of the high-pressure pump is also connected to the air vortex tube device 3. A three-way ball valve is installed between the high-pressure pump and the clean water tank. The three-way ball valve is connected to the high-pressure reel, and the high-pressure reel is connected to the nozzle. The other end of the three-way ball valve is connected to the air vortex tube device 3. The high-temperature air discharged from the air vortex tube device 3 enters the clean water tank, the high-pressure pump, and the three-way ball valve to heat the high-pressure water system 5, thus preventing the high-pressure water system 5 from freezing. The operation of the high-pressure water system 5 is controlled by the three-way ball valve. When opened, the water in the clean water tank is filtered through the water filter, enters the high-pressure pump and the high-pressure reel 11, and is then sprayed out through the nozzle to clean the pipes and unclog blockages.

[0021] A safety valve is installed on the high-pressure pump, and an unloading valve is installed between the high-pressure pump and the three-way ball valve. The safety valve protects the high-pressure pump, and the unloading valve prevents excessive load between the high-pressure pump and the three-way ball valve, thus avoiding affecting the water flow.

[0022] The gas vortex tube device 3 includes a tube body 7, with a high-temperature gas outlet 6 and a low-temperature gas outlet 10 at both ends of the tube body 7. An air inlet 8 is provided on the tube body 7, and a guide tube is provided inside the air inlet 8. The high-temperature gas outlet 6 is connected to the high-pressure water system 5, and the low-temperature gas outlet 10 is connected to the fan system 2. The high-temperature gas enters the high-pressure water system 5 to heat the water and play an antifreeze role, while the low-temperature gas enters the fan system 2 to dissipate heat and cool the fan.

[0023] The temperature control system 4 includes a temperature sensor and an electronic control system. The temperature sensor detects the outdoor temperature, and the electronic control system controls the high-pressure water system 5 and the fan system 2. The detection results of the temperature sensor are transmitted to the electronic control system, which is connected to the three-way ball valve of the high-pressure water system 5. The electronic control system adjusts the working status of the high-pressure water system 5 and the fan system 2 according to the outdoor temperature detected by the temperature sensor. When the temperature is below 4℃, the three-way valve of the high-pressure water system 5 is opened for antifreeze drainage. When the temperature is below 0℃, the three-way valve of the high-pressure water system 5 can be opened for antifreeze drainage. It can realize antifreeze drainage reminder and automatic drainage. The antifreeze drainage system can realize cold and hot separation, using high-temperature air for antifreeze drainage and cold air for fan side air supply and operation cooling. It realizes high-pressure water antifreeze drainage and fan cooling, ensuring that the cleaning and vacuum truck will not freeze or crack due to the operator forgetting to drain or the water not being drained completely. At the same time, it assists in the heat dissipation of the fan. Example

[0024] Based on Embodiment 1, an implementation method for a high-pressure water circuit antifreeze drainage system for a vacuum cleaning truck is provided: The blower system 2 is a Roots pump blower, which is connected to the chassis power take-off system 1.

[0025] Unlike Embodiment 1, the chassis power take-off system 1 drives the Roots pump blower, which creates negative pressure in the sludge suction tank and at the same time creates a high-speed airflow near the suction pipe inlet to bring the material into the sludge suction tank. It can suck up non-liquid materials such as mud, solids, and dust.
