Technical Field
The application belongs to the technical field of dust cleaning of solar photovoltaic panels, and relates to a high-efficiency energy-saving dust removing device for solar photovoltaic panels.
Background
Photovoltaic power generation is a green new energy source, and rapid development is achieved in recent years. Despite the great improvements in photovoltaic technology, dust accumulation on the surface of solar electric floors, blocking a portion of the incident sunlight, remains a significant challenge for the industry.
In order to make full use of sunlight, many large-scale solar power plants are built in open-land, sunny geographical areas, such as desert areas. Although this is advantageous for solar power generation, there is often a lot of dust in these areas, which accumulate on the surface of the solar panel and block part of the sunlight, thereby reducing the power generation efficiency. According to statistical data, in a dry desert area with little rain, the loss of the output power of the photovoltaic module caused by dust accumulation is 15%, the highest loss can be 30%, and the annual average power generation efficiency loss is 6%. Therefore, solar panels generally require periodic cleaning, and the most commonly used cleaning method at present is to use pressurized water spray or mist, which requires a large amount of pure water for cleaning. The water for cleaning, due to the lack of water in the desert area, requires water to be transported from a remote place, thereby increasing the operation and maintenance costs of the solar power plant. To reduce water consumption, some small-scale power stations perform manual scrubbing or robotic dry cleaning, but are prone to introducing irreversible surface scratches, thereby reducing light transmittance.
Aiming at the problems, the application provides a device for removing dust on a solar cell panel by utilizing high-voltage direct current pulse, namely a novel dust removing method of the solar cell panel, which is suitable for desert areas lack of water.

Description of the embodiments

Wherein the light-transmitting conductive material 2 is used as a positive electrode, and the light-transmitting metal grid 3 is used as a negative electrode.
The light-transmitting metal mesh grids 3 are arranged above the light-transmitting conductive material 2 at intervals, the light-transmitting conductive material 2 is covered above the solar photovoltaic panel 1 to form a light-transmitting dust-proof layer, the light-transmitting conductive material 2 is obliquely arranged compared with the horizontal plane, and dust discharge ports are reserved on the bottom sides of the light-transmitting conductive material 2, so that dust on the surface of the light-transmitting conductive material 2 can conveniently flow downwards to the light-receiving area of the Fang Yichu photovoltaic panel under the action of a direct-current high-voltage electrostatic field, and the purpose of removing the dust is achieved.
Referring to fig. 1, a solar photovoltaic panel 1 is disposed obliquely with respect to a horizontal plane, and a light-transmitting conductive material 2 is adjacent to and parallel to an upper surface of the solar photovoltaic panel 1. The light-transmitting conductive material 2 can be connected with the upper surface of the solar photovoltaic panel 1 in an insulating and sealing way, so that dust is prevented from entering a gap between the light-transmitting conductive material 2 and the solar photovoltaic panel 1.
The light-transmitting conductive material 2 is a hard material and is selected from light-transmitting conductive glass, light-transmitting glass with a light-transmitting conductive coating or glass covered with a light-transmitting conductive plastic sheet, the light transmittance of the light-transmitting conductive material 2 is 70% -95%, and the resistance between 55 cm in a conductive area is preferably less than 25 ohms. Because the conductive layer is to be electrically connected, the connection must be reliable. The light-transmitting conductive material 2, whether it is in contact with the photovoltaic panel or not, must be mechanically reliably fixed.
The inclination angle of the light-transmitting conductive material 2 with respect to the horizontal plane may be >10 °.
In use, the two high-voltage electrodes of the device are covered above the photovoltaic cell panel, so that sunlight is not (extremely) blocked to irradiate on the photovoltaic cell panel, and the device is pressurized at regular time or according to needs, so that dust deposited on the surface of the conductive glass moves out of the photovoltaic cell panel, and the purpose of removing the dust blocking the light is achieved. The pressurization referred to herein is a high-voltage electrostatic field, and as shown in fig. 2, a pulse wave signal is generated under pressurization. Under the action of the direct current high-voltage electrostatic pulse, dust falling on the surface of the high-transmittance conductive glass is forced to induce the same polarity (namely, the transparent conductive material 2 is selected as the transparent conductive glass), and the dust leaves the surface in the direction perpendicular to the surface of the transparent conductive glass under the action of the same polarity repulsion and opposite polarity attraction, and falls vertically under the action of the pulse due to the pulse. Because the light-transmitting conductive glass is obliquely arranged, dust slides down as if it were floating above the glass surface.
The principle verification experiment proves that under the condition that the transparent conductive glass is inclined by 20 degrees, dust only needs tens of seconds to slide out of the electrode area from the surface of the glass. The inclination degree of the transparent conductive glass is influenced by the latitude of the photovoltaic power station, the inclination angle of a high latitude area can reach more than 40 degrees, and dust almost instantaneously slides out of the electrode area under the condition.
The light-transmitting metal mesh 3, which is one of the high-voltage electrostatic field electrodes, includes a frame and a light-transmitting mesh woven on the frame with stainless steel wires. The diameter of the stainless steel wire is 0.01-1mm. The stainless steel wires are arranged in parallel at intervals on the frame to form a row of row lines, each row line is horizontally arranged, therefore, the row lines are perpendicular to the macroscopic discharge direction of dust on the surface of the transparent conductive material 2, the distance between every two adjacent stainless steel wires is 10-50mm, the wires are required to be tightened, excessive sagging is not allowed, the electrode distance is too small to cause high-voltage breakdown, and the steel wire mesh grid can be fixed by a metal frame or an insulating material frame, but must be reliably connected with electricity.
In the device, the direct-current high-voltage power supply device comprises a low-voltage direct-current power supply and a high-voltage direct-current pulse generator 4, wherein the high-voltage direct-current pulse generator 4 is connected with the low-voltage direct-current power supply, and the high-voltage direct-current pulse generator 4 can generate high-voltage static electricity under the power supply effect of the low-voltage direct-current power supply so as to form a direct-current high-voltage electrostatic field formed by the high-voltage direct-current pulse electricity between the two conductive electrodes. In contrast to fig. 1, a control switch 5 is provided on the supply line of the high-voltage dc pulse generator 4 on the low-voltage dc power supply side.
The high voltage DC pulse generator is a component for generating DC high voltage static electricity, and can generate high voltage static electricity under the condition of low voltage DC power supply, the electromotive force (voltage difference) of the high voltage DC pulse generator is different depending on the property of dust, and the property of the dust is 4000VDC-50000VDC, and the property of the dust refers to sand dust mainly containing silicon dioxide, dry cohesive soil dust and other dust. The pulse high voltage can be rectangular, trapezoidal or triangular (see figure 2), and the key is to ensure the voltage value of the electrostatic field and the carrying capacity and no-load carrying capacity.
The frame of the light-transmitting metal grid 3 is arranged on an insulating bracket in a manner of moving up and down or rotating, and the bottom of the insulating bracket is fixedly arranged on a fixing member beside the solar photovoltaic panel 1. Therefore, the light-transmitting metal mesh 3 can be separated from the light-transmitting conductive material 2 by a distance, and the purpose is that when sticky dust is adhered to the conductive electrode by excessive moisture, the light-transmitting metal mesh 3 can be opened to manually clean dust adhered to the surface of the light-transmitting conductive material 2.
It should be noted that the device has no moving parts, such as a motor, and can work immediately after power is supplied, thus being very suitable for radio remote control. If the power supply of the direct current high voltage generator is taken from the photovoltaic cell, the device is simpler and is convenient to popularize and apply.
The insulating component of the device refers to a special component for fixing the photovoltaic device and keeping the relative position of the photovoltaic device, and the insulating component has an insulating requirement because of the high direct current voltage during operation.
The application is based on the high-voltage direct current pulse dust removal technology, which consists of a direct current power supply, a high-voltage direct current pulse generator, positive electrode conductive glass, negative electrode steel wire mesh grid and a control switch, wherein the high voltage is applied to the positive electrode conductive glass and the negative electrode steel wire mesh grid by opening the control switch through connection of wires, so that a high-voltage electrostatic field is generated, sand particles scattered on the conductive glass are separated rapidly, and the sand particles rapidly slide out of an electrode area from the surface of the glass under the condition that the conductive glass is inclined by 20 degrees, thereby achieving the aim of removing dust. As a result of measurement, the removal rate of sand and dust was 95% or more.

After the device is used for removing dust, the daily average power generation capacity of a photovoltaic array can be improved by about 5%, and a 10 megawatt photovoltaic power station is taken as an example, so that the power generation capacity can be increased by about 50 ten thousand Kw-h in the whole year, the economic benefit is increased by about 45 ten thousand yuan, and remarkable economic benefit and social benefit are achieved.
