An access port is arranged at the upper end of the water tank 10.

In some specific examples of the present utility model, the implementation path of the present solution is as follows:

1. the chassis power system alone provides power to the chassis. The chassis fuel tank provides fuel to both the chassis and the second engine 210. Meanwhile, an electromagnetic on-off valve is additionally arranged between the oil supply of the chassis fuel tank and the branching of the oil pipe to control an oil way.

2. The second engine 210 transmits power to the high-pressure water pump 40 through a belt. The waterway system is driven by the high-pressure water pump 40.

The novel garbage can cleaning vehicle 1000 has two modes of high-pressure waterway operation and garbage can operation, which are respectively as follows:

3. high-pressure waterway operation mode: cleaning a garbage can or the ground and other operation scenes;

4. garbage collection mode: the garbage is manually collected from the side feed port of the garbage can 300, and the garbage can 300 is tipped to be unloaded at a designated place.

The novel garbage can cleaning vehicle 1000 has the functions of conventional garbage can cleaning and garbage collection, and can also be used for deep cleaning (15 MPa) scouring with higher pressure on the ground with more stains such as walking streets, snack streets and the like and heavier greasy dirt. The two cleaning operation modes are supported simultaneously by a single pump, and the cleaning operation modes can be independently selected by controlling a manual high-pressure ball valve.

The discharging of the dustbin 300 is realized by taking the electric chassis storage battery through the power unit, controlling the lifting oil cylinder of the dustbin 300 lifting mechanism 400 to stretch and retract, and achieving the purposes of discharging garbage and resetting the dustbin 300.

In some specific examples of the present utility model, waterway schemes and implementation paths:

the garbage can cleaning vehicle 1000 is provided with a novel high-pressure waterway system 20, supports two sets of system parallel operation of high-pressure cleaning and high-pressure steam cleaning, and has a steam backflow prevention function, and is based on the specific waterway principle: the high pressure water pump 40 is operated by the second engine 210 or other power transmission to suck water out of the water tank 10, and the pressure is monitored by the pressure gauge after the water is filtered. The high-pressure water reaches the water diversion pipe 90 of the high-pressure pipeline after passing through the automatic unloading valve 50 (10 Mpa), and the water pressure exceeds 10Mpa at the moment to be automatically unloaded, and the manual unloading can be performed through the unloading ball valve. At this time, both high-pressure cleaning and high-pressure steam cleaning can be performed through the water diversion pipe 90.

1. "high pressure cleaning" mode:

the manual high-pressure ball valve for opening the high-pressure waterway is provided with a handheld spray gun through a quick-change connector for cleaning the garbage can or the ground under high pressure, and the high-pressure water pipe connector can be arranged at the center of the outside of the high-pressure cleaning reel 610, and the handheld spray gun is arranged at the tail end of the high-pressure water pipe for performing obstacle-crossing high-pressure cleaning.

2. "high pressure steam wash" mode:

the manual high-pressure ball valve of the high-temperature high-pressure steam waterway is opened, and high-pressure water overflows through the overflow valve 37, so that the pipeline is ensured not to be overpressurized. While the high pressure water passes through the check valve 32 and the flow switch, the check valve 32 prevents the back flow of steam. The heater 31 is activated by the flow switch to generate high-temperature and high-pressure steam. The steam passes through a steam safety valve 36 to ensure no overpressure, and a temperature and pressure sensor 34 is installed on the high-temperature and high-pressure steam waterway to monitor the steam. The handheld spray gun is arranged at the tail end of the high-temperature high-pressure steam waterway, so that high-temperature cleaning operation can be performed.

3. Stop working: the unloading ball valve of the water diversion pipe 90 is used for manually unloading when the work is required to be stopped, so that the service lives of other waterway elements are prolonged.

As shown in fig. 7, in some specific examples of the present utility model, the waterway control method: after the control command is issued, the waterway controller judges whether the waterway control system is faulty, if yes, an alarm is given, and if no, an electric signal is transmitted to the second engine 210, and the second engine 210 is started to drive the water pump 40. And high-pressure cleaning is selected, and the water outlet of the water pump 40 is switched to the high-pressure waterway operation. The steam cleaning is selected, the water outlet of the water pump 40 is switched to the steam cleaning valve, the water is fed to the heater 31 through the flow switch, a flow switch signal is input to the water inlet channel controller, the heater 31 starts to work at the moment, and when the flow switch has no signal feedback, the heater 31 stops working. The water outlet of the heater 31 is provided with a temperature transmitter and a pressure transmitter, and provides signals of temperature and pressure to the waterway controller. The temperature transmitter and the pressure transmitter are both provided with preset values, and the heater 31 stops working as long as the high temperature or the high pressure of the high temperature steam exceeds the preset values; below the preset value, the heater 31 continues to operate, generating high temperature steam.

As shown in fig. 8, the garbage can lifting control: the garbage can lifting control command is given to the power unit, and the lifting oil cylinder of the garbage can 300 is directly controlled to stretch and retract through the power unit.

The utility model has the following advantages:

1. the use of hydraulic components is reduced, the leakage risk of hydraulic oil is reduced, the structure is simple, and the equipment reliability is improved.

2. The addition of the check valve 32 eliminates the risk of high pressure steam flowing back to the water inlet line of the heater 31, improving the safety of the product.

3. The product economy is greatly improved.
