Description

Cleaning device

Technical field

The utility model relates to cleaning equipment field, particularly relates to cleaning device.

Background technology

Study according to pertinent literature and record, 4g/m ²dust accretions make that the electric energy delivery efficiency of photovoltaic module is sharp falls 60%.What is more, and bird excrement, leaf, the animal climbing lighttight pollutant covering of bulk such as traces can produce hot spot effect, causes photovoltaic module localized regions of elevated temperature until burn and scrap.As can be seen here, the surface cleanness of photovoltaic module not only affects the generating efficiency of photovoltaic module, also affects the life-span of photovoltaic module.

In order to promote the generating efficiency of photovoltaic module, just must ensureing the cleannes of photovoltaic module, in prior art, usually having following several mode for addressing this problem:

One is artificial cleaning mode, and regularly hold instrument (such as cleaning brush etc.) by workman and clean photovoltaic module surface, the water consumption of this cleaning mode is low, and expense is low.But labour intensive, not manageability, cleaning effect uniformity is poor, and efficiency is low, and easily treating clean surface causes artificial damage simultaneously.

The second way utilizes the giant that waterwheel carries or underground pipe connects to clean, and advantage is that cleaning effect is good, and shortcoming is that water consumption is large, and adaptive capacity to environment is poor, simultaneously easily causes high pressure to damage to clean surface, and engineering input is larger.

The third mode adopts spray system, and which does not need artificial participation, and cleaning speed is fast, be applicable to roof photovoltaic, but cleaning effect is bad, and water consumption is large, and adaptive capacity to environment is poor, and engineering drops into larger.

4th kind of mode uses the professional equipments such as cleaning cart, advantage is that water consumption is less, cleaning effect is good, shortcoming is to adapt to physical features complex environment or place, simultaneously vehicle-mounted hairbrush brings different pressures to cell panel surface diverse location in cleaning cart is advanced, require higher to the professional skill of cleanup crew, buying simultaneously drops into larger.

5th kind is adopt cleaning device or robot to clean, thus realizes low water consumption, high efficiency, low-intensity, few people or unmanned automated cleaning.Particularly, cell panel is installed the cleaning device that can load and unload flexibly, needing the solar panel carrying out cleaning moves, the cleaning brush on it rotates and cleans the surface of solar panel.But, because these cleaning devices carry single hairbrush, round brush or scraper plate usually as burnisher, therefore the cleaning device or the robot that only carry hairbrush or round brush in use need repeated multiple times clean cell panel to reach cleaning purpose, efficiency is lower, effectively cannot remove accumulated snow and bulk pollutant simultaneously.In addition, the cleaning device or the robot that only carry wiper need to clean in the presence of water, otherwise easily cause photovoltaic panel surface scratches; And because need with water, the seasonal adaptation therefore carrying the cleaning device of wiper is indifferent.

To sum up, the existing cleaning device that cleans solar panel or machine can not clean solar panel per capita effectively.

Edge in the inclination that time clean, cleaning device assists wheels 451 by top, bottom is assisted wheels 453 and side to assist wheels 452 to block to be placed on solar panel, ensures that cleaning device walking motion is steady, smooth and easy, does not occur derailing, the phenomenons such as skidding.

After placing, cleaning device starts, and power supply control portion 60 sends clean instruction, and the first drive motors is powered and starts, and the first cleaning item carries out clockwise or counterclockwise rotary motion with controlled speed as required, carries out transverse direction clean solar panel; Second drive motors is powered and starts, second cleaning item 31 longitudinally rotates while the horizontal rectilinear motion of cleaning device and the first cleaning item spin-cleaning, the second cleaning item 31 contacted with solar panel carries out linear longitudinal movement relative to solar panel, carries out longitudinal straight line cleaning action to solar panel according to controlled speed; 3rd drive motors is powered and starts, and walking assembly 40 starts walking, drives whole cleaning device to move on solar panel.Realize thus cleaning the intersection that solar panel carries out horizontal and vertical both direction, to ensure can realize good cleaning effect with less cleaning time simultaneously.

Meanwhile; the rim detection wheel 54 of rim detection assembly detects the edge whether cleaning device moves to solar panel; when cleaning device moves to the edge of solar panel; rim detection is taken turns 54 unsettled, the first end touching gauge tap 51 of swing arm 52, and power supply control portion 60 receives the signal of gauge tap 51; control logic according to presetting judges; perform and move back and forth or shut down, realize repeatedly clean or shut down, completing clean grade for action.

In this course of work, by the first cleaning section 20 of transverse direction and the cross action of the second longitudinal cleaning section 30, when cleaning pollutant (floating dust, accumulated snow, leaf etc.) on solar panel, cleaning device is walked 1 time, then clean number of times and be equivalent to 3 times, and the second cleaning item 31 being arranged on the first cleaning item both sides forms with housing the barrier effectively blocking airborne dust, prevents cleaning process to the secondary pollution of solar panel; Simultaneously, first cleaning section 20 and the second cleaning section 30 are cleaned direction and have been carried out twice transformation in cleaning course, make the stressed more complicated of pollutant, more easily realize the fragmentation of pollutant, upspring, the cleaning direction of adding the second cleaning item 31 is top-down, to the acceleration that the pollutant cleaned is downward, accelerate the discharge of pollutant, be unlikely to disposablely thoroughly to clean or increase unnecessary manual intervention because of the accumulation of pollutant, achieve the efficient, high-quality of cleaning works.

Cleaning device of the present utility model has following effect:

This cleaning device can have stronger adaptive capacity to environment in centralized photovoltaic plant or distributed photovoltaic power station, by increasing in the both sides of the first cleaning section realizing laterally cleaning the second cleaning section realizing longitudinally cleaning, mating reaction both allowing, thus make this cleaning device seasonal adaptation ability strong, when anhydrous clean can realize cleaning purpose with less cleaning time, and accumulated snow, bulk pollutant etc. can be cleaned.

On the other hand, will walk assembly and rim detection Components integration integrated, make this cleaning device can realize seeking limit detection without the need to arranging limiting bracket at the edge of solar panel.Meanwhile, the running part of this cleaning device adopts the form of single motor direct-connected power transmission shaft, and transmission efficiency is high, provides stronger walking power.

The above; be only detailed description of the invention of the present utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; change can be expected easily or replace, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of described claim.
