Description

A kind of multifunction energy-saving cleans vehicle
Technical field
The present invention relates to a kind of cleaning vehicles, and vehicle is cleaned more particularly, to a kind of multifunction energy-saving.
Background technology
Traditional cleaning ground health is the work of a burdensome, particularly in some big public places, it is necessary to Expend more manpower and time.Such as the worker that mops floor will spend a very long time come the railway station that drags a clean Waiting hall, midway will also ceaselessly be gone to clean dirty mop and change water, consume the water resource of many preciousnesses.And currently Some intellective dust collectors of research and development, what it is due to aiming is all high end home market, manufactures cost and use cost too It is high, it is difficult to promote and apply.
In addition, with the quickening of modern life rhythm and the requirements such as raising of the degree of automation.Since people are busy with one It work, after going home, just without muscle power with energy high intensity solution work, therefore, for it is a can high-efficiency cleaning, The rapid automatized cleaning products of energy just become to be highly desirable to again.Meanwhile people are also increasingly heavier for the concern of environmental resource Depending on energy saving concept also gos deep into people's daily life.The design of product will be compatible with the considerations of multiple functions.
At present, some automatic cleaners that some scientific research institutions and manufacturer are researching and developing, their work It needing to consume more electric energy, cleaning intensity is not high, and their design object is also mainly used for indoor, domestic applications, It is difficult to meet actual demand.Need to produce a kind of production of the water-saving cleaning ground health for meeting practical application of real environmental protection and energy saving Product.
The content of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of multifunction energy-saving is clear Clean vehicle.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of multifunction energy-saving cleans vehicle, including moveable car body, the solar energy storage machine being installed on carbody canopy Structure and vehicle body and the refuse sweeping mechanism and mopping ground that are sequentially arranged by direct of travel are arranged on, wherein,
The refuse sweeping mechanism includes rotary broom component, is arranged on rotary broom component rear and receives temporary rotation Turn broom component and clean the dustpan component of rubbish and the dustbin for receiving rubbish in dustpan component;
The mopping ground includes water tank and the component that mops floor for being arranged in water tank rear;
The solar energy storage energy supply mechanism includes solar cell panel assembly and connects with solar cell panel assembly The energy storage for connecing and being used to provide power source to car body, refuse sweeping mechanism and mopping ground energizes component.
Preferably, the rotary broom component includes electric rotating machine, two rotary brooms, two rotation axis and two rotations Rotating disk, described two rotation gears are engaged and are separately positioned in the rotation axis of a connection rotary broom, described One in two rotation axis exports axis connection with electric rotating machine and is driven by it rotating.Rotation gear is driven using electric rotating machine Rotation so that two rotary brooms relatively rotate, and then coordinate together to bring the rubbish in front into and sweep into dustpan component.
It is furthermore preferred that lifting assembly moving up and down is installed, on lifting assembly described in setting in the car body Rotary broom component, and lifted by lifting assembly, adjust the upright position of rotary broom component so that rotary broom can be by rubbish Rubbish is swept into dustpan component.The purpose of lifting assembly is set primarily to adjusting height of the rotary broom component apart from ground, So that its one side is adapted to the cleaning works of different road conditions.
