Hybrid dust absorption environmental sanitation vehicle and hybrid sweeping environmental sanitation vehicle

Abstract

The invention relates to a hybrid vacuum sweeper. A chassis is provided with an engine, a gear transfer case, a silicon rectifying generator, a storage battery, a power converter, a motor, a dustbin, a suction tube, a suction cup, a fan, a water tank and a water pump. The engine drives the silicon rectifying generator and the fan respectively. The silicon rectifying generator is connected with the power converter and the storage battery to output generated electric current. The power converter is connected with the motor to drive a rear axle shaft to drive the vacuum sweeper to run. The fan sucks dust and garbage on the ground in front of the suction cup into the dustbin through the dustbin, the suction tube and the suction cup. The water pump pumps water from the water tank to control the dust in the suction tube and the suction cup by a wet method. In the invention, a hybrid drive technology is applied to a special urban environment sanitary vehicle with vehicle-mounted operating devices, and the special vehicle has an oil-saving effect due to the use of a single engine as well as good operation effects; and a hybrid drive mechanism continuously generates electricity and overcomes the drawback that an electrical vehicle can not work for a long time due to the limitation from the capacity of the storage battery.

Description

technical field [0001] The invention relates to a hybrid power sanitation equipment, in particular to a hybrid power dust-absorbing sanitation vehicle and a hybrid power sweeping sanitation vehicle. Background technique [0002] At present, more and more mechanized equipment has been used for urban road cleaning, and vacuum cleaners and sweepers have been widely used. In sanitation vehicles with on-board operating devices, such as sweeping vehicles, high-pressure washing vehicles and other special sanitation vehicles, two engines are generally installed on large and medium-sized vehicles. The main engine is responsible for driving the vehicle, and the auxiliary engine is responsible for providing stable power. Drive the vehicle-mounted operating device to work. On small sanitation vehicles, due to the limited space of the vehicle, a single engine is generally used to drive multiple hydraulic pumps in series, and several hydraulic pumps drive hydraulic motors to drive the ve...

Problems solved by technology

The shortcomings of the above patents are low transmission efficiency and high fuel consumption of hydraulic transmission

[0008] At present, it is still difficult to find information on the application of hybrid electric vehicle technology to sanitation vehicles such as vacuum cleaners and floor sweepers. The application of this technology requires not only variable power to meet the variable speed of the vehicle, but also stable power to drive the vehicle-mounted operating device. To work, it is also necessary to be able to work continuously for a long time to meet uncertain cleaning tasks. The operating system that meets the requirements of motor vehicles must be configured in the cab to adapt to the driving habits of drivers and avoid traffic accidents; the structure of sanitation vehicles is also It must be advanced, whether sweeping and sweeping the floor should not raise dust, whether the fan exhaust should spray dust, there should be no traces of mud mixed with water and dust on the cleaned ground, and it must be able to work in freezing weather and rainy days; vehicles High transmission efficiency, low emissions and low fuel consumption
