Abstract

The present invention proposes a kind of photovoltaic plant cleaning systems and control method thereof, round-the-clock automatic washing is carried out for counter plate glass, solve the problem affecting generated output and generation hot spot effect because face glass dust foreign material cover, and then improve generating efficiency and the service life of photovoltaic plant.Photovoltaic plant cleaning systems of the present invention comprise the framework for installation panel glass, framework are provided with motor and pulley, and on pulley, adjustable shelf is provided with and utilizes described motor-driven steel wire, and steel wire is fixed with cleaner.Its control method is as follows: motor utilizes timer to carry out timing, and utilizes rainwater inductor to detect whether have precipitation; If do not have precipitation in scheduled time length, then control unit control cleaner cleans; If have precipitation in the given time, then control unit stops timing when precipitation, and controls cleaner and clean; Control unit utilizes timer to restart timing after each cleaning.

Description

A kind of photovoltaic plant cleaning systems and control method thereof
Technical field
The invention belongs to technical field of solar utilization technique, be related specifically to a kind of photovoltaic plant cleaning systems and control method thereof.
Background technology
The life-span of photovoltaic plant is 20-30, and its face glass is chronically exposed in air, and dust is attached on glass can have a strong impact on light transmission, even can form hot spot effect, the whole assembly of final breaking-up.Present photovoltaic plant is without special cleaning equipment, and its face glass is the cleaning by rainwater, cannot ensure the clean of cell panel in the area that the large rainwater of dust storm is few, is therefore difficult to the generating efficiency and the service life that ensure photovoltaic plant.
Summary of the invention
The object of the invention is to propose a kind of photovoltaic plant cleaning systems and control method thereof, round-the-clock automatic washing is carried out for counter plate glass, solve the problem affecting generated output and generation hot spot effect because face glass dust foreign material cover, and then improve generating efficiency and the service life of photovoltaic plant.
Photovoltaic plant cleaning systems of the present invention comprise the framework for installation panel glass, described framework are provided with motor and pulley, and on described pulley, adjustable shelf is provided with and utilizes described motor-driven steel wire, and described steel wire is fixed with cleaner.
Further, for the time of clean face plate more intelligently can be controlled, utilize rainwater as far as possible, in the control unit of described motor, be provided with timer and rainwater inductor.
Further, described motor is installed on the middle part of framework, and described cleaner has two, and lays respectively at the both sides of motor.Such motor, when rotating, can drive the cleaner of its both sides to work, more simultaneously.
Further, described pulley is provided with the hold down gag for compressing steel wire, loosens to prevent steel wire.
Further, described rainwater inductor is humistor, and humistor is after chance water, and its resistance significant change can occur, and can know whether have precipitation to occur by this characteristic.
The control method of above-mentioned photovoltaic plant cleaning systems comprises the steps: that the control unit of motor utilizes timer to carry out timing, and utilizes rainwater inductor to detect whether have precipitation; If do not have precipitation in scheduled time length, then control unit controls electric machine rotation, drives cleaner counter plate glass to clean by steel wire; If have precipitation in the given time, then control unit stops timing when precipitation, and controls electric machine rotation, drives cleaner counter plate glass to clean by steel wire; Control unit utilizes timer to restart timing after each cleaning.
Further, when glass sheet carries out clean over there, described control unit by controlling the rotation direction of motor, thus drives cleaner to move back and forth along steel wire.
Photovoltaic plant cleaning systems structure of the present invention is simple, cost is low, simple installation, goes for different length and up-and-down photovoltaic plant, and data show that this kind of cleaning can raise the efficiency more than 10% by experiment, have good practicality.
Accompanying drawing explanation
Fig. 1 is the structural representation of photovoltaic plant cleaning systems of the present invention.
Fig. 2 is the structural representation of the hold down gag of embodiment 1.
Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, the effect and operation principle etc. of the specific embodiment of the present invention as the mutual alignment between the shape of involved each component, structure, each several part and annexation, each several part are described in further detail.
Embodiment 1:
As shown in Figure 1, the photovoltaic plant cleaning systems of the present embodiment comprise the framework 1 for installation panel glass, framework 1 are provided with motor 2 and pulley 3, and on pulley 3, adjustable shelf is provided with the steel wire 4 utilizing described motor 2 to drive, and steel wire 4 is fixed with cleaner 5.Wherein, motor 2 is installed on the middle part of framework 1, and described cleaner 5 has two, and lays respectively at the both sides of motor 2.
Be provided with timer and rainwater inductor in the control unit of motor 2, in the present embodiment, utilize humistor to serve as rainwater inductor.
As shown in Figure 2, pulley 3 is provided with the hold down gag for compressing steel wire 4, hold down gag is made up of spring 6 and contact roller 7, wherein contact roller 7 is between spring 6 and pulley 3, steel wire 4 is between pulley 3 and contact roller 7, contact roller 7 is pressed on steel wire 4 by the elastic force of spring 6, and steel wire 4 is oppressed by pulley 3, contact roller 7 simultaneously, loosens (steel wire not shown in FIG.) to prevent steel wire 4.
The control method of above-mentioned photovoltaic plant cleaning systems comprises the steps:
The control unit of motor 2 utilizes timer to carry out timing, and utilizes rainwater inductor to detect whether have precipitation; If do not have precipitation in scheduled time length (such as 48 hours), then control unit control motor 2 rotates, and drives the cleaner 5 counter plate glass of its both sides to clean by steel wire 4; If have precipitation in the given time, then control unit stops timing when precipitation, and controls motor 2 and rotate, and drives the cleaner 5 counter plate glass of its both sides to clean by steel wire 4; Control unit utilizes timer to restart timing, until again carry out clean face plate when timing terminates or runs into precipitation after each cleaning.
When glass sheet carries out clean over there, control unit by controlling the rotation direction of motor 2, thus drives cleaner 5 to move back and forth along steel wire 4.
