Abstract
The invention provides a cleaning system for a photovoltaic power station and a control method thereof. The cleaning system for the photovoltaic power station and the control method of the cleaning system are used for conducting all-weather full-automatic cleaning on panel glass and solve the problems that the electricity generating power is affected and the hot spot effect is generated due to the fact that the panel glass is covered by dust and sundries, thereby improving the electricity generating power of the photovoltaic power station and prolonging the service life of the photovoltaic power station. The cleaning system for the photovoltaic power station comprises a framework used for installing the panel glass, a motor and a pulley are installed on the framework, a steel wire which is driven by the motor is movably erected on the pulley and a cleaner is fixed to the steel wire. The control method of the cleaning system comprises the following steps that timing is conducted through a timer and a rain sensor is used for detecting whether rainfall exists or not; if rainfall does not exist in a preset time span, a control unit controls the cleaner to conduct cleaning; if rainfall exist in a preset time, the control unit enables timing to be stopped when rail falls and controls the cleaner to conduct cleaning; the control unit enables timing to be started again through the timer every time cleaning is completed.

Summary of the invention
The object of the invention is to propose cleaning systems and control method thereof for a kind of photovoltaic plant, for counter plate glass, carry out round-the-clock automatic washing, the problem that solution affects generated output and produces hot spot effect because face glass dust foreign material cover, and then generating efficiency and the service life of improving photovoltaic plant.
Photovoltaic plant of the present invention comprises the framework for installation panel glass with cleaning systems, and motor and pulley are installed on described framework, and on described pulley, adjustable shelf is provided with and utilizes described motor-driven steel wire, on described steel wire, is fixed with cleaner.
Further, for more intelligently controlling the time of clean face plate, utilize rainwater as far as possible, in the control module 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.Motor, when rotating, can drive the cleaner of its both sides to work simultaneously like this, more efficient.
Further, described pulley is provided with for compressing the hold down gag of steel wire, loosening to prevent steel wire.
Further, described rainwater inductor is humistor, and humistor is after meeting water, and significant change can occur its resistance, by this characteristic, can know whether have precipitation to occur.
Above-mentioned photovoltaic plant comprises the steps: that by the control method of cleaning systems the control module of motor utilizes timer to carry out timing, and utilizes rainwater inductor to survey whether to have precipitation; If there is no precipitation in scheduled time length, control module is controlled electric machine rotation, by steel wire, drives cleaner counter plate glass to clean; If there is in the given time precipitation, control module stops timing when precipitation, and controls electric machine rotation, by steel wire, drives cleaner counter plate glass to clean; Control module utilizes timer to restart timing after each cleaning.
Further, when glass sheet cleans over there, described control module is by controlling the rotation direction of motor, thereby drive cleaner moves back and forth along steel wire.
Photovoltaic plant of the present invention is simple in structure with cleaning systems, 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 cleaning systems for photovoltaic plant of the present invention.
Fig. 2 is the structural representation of the hold down gag of embodiment 1.
The specific embodiment
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present invention is described in further detail as the effect of the mutual alignment between the shape of each related member, structure, each several part and annexation, each several part and operation principle etc.
Embodiment 1:
As shown in Figure 1, the photovoltaic plant of the present embodiment comprises the framework 1 for installation panel glass with cleaning systems, and motor 2 and pulley 3 are installed on framework 1, and on pulley 3, adjustable shelf is provided with the steel wire 4 that utilizes described motor 2 to drive, and is fixed with cleaner 5 on steel wire 4.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.
In the control module of motor 2, be provided with timer and rainwater inductor, in the present embodiment, utilize humistor to serve as rainwater inductor.
As shown in Figure 2, pulley 3 is provided with for compressing the hold down gag of steel wire 4, hold down gag consists 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, the elastic force of spring 6 is pressed in contact roller 7 on steel wire 4, makes steel wire 4 simultaneously by pulley 3, contact roller 7 compressings, to prevent steel wire 4 loosening (steel wire not shown in FIG.).
Above-mentioned photovoltaic plant comprises the steps: by the control method of cleaning systems
The control module of motor 2 utilizes timer to carry out timing, and utilizes rainwater inductor to survey whether to have precipitation; For example, if there is no precipitation in scheduled time length (48 hours), control module is controlled motor 2 rotations, by steel wire 4, drives the cleaner 5 counter plate glass of its both sides to clean; If there is in the given time precipitation, control module stops timing when precipitation, and controls motor 2 and rotate, and by steel wire 4, drives the cleaner 5 counter plate glass of its both sides to clean; Control module utilizes timer to restart timing after each clean, until clean face plate is carried out in timing when finishing or running into precipitation again.
When glass sheet cleans over there, control module is by controlling the rotation direction of motor 2, thereby drive cleaner 5 moves back and forth along steel wire 4.
