Description

一种用于太阳能电池板的清洁装置Cleaning device for solar panel 技术领域Technical field
本发明涉及清洁技术领域,更具体地说,它涉及一种用于太阳能电池板的清洁装置。This invention relates to the field of cleaning technology and, more particularly, to a cleaning apparatus for solar panels.
背景技术Background technique
随着世界生产经济的迅猛发展和全球人口的不断增加,原先以化石能源为主的不可再生能源日益减少,同时化石能源引起的生态污染对人类赖以生存的环境造成了严重破坏。然而以太阳能为主的新型能源成为了可再生能源的主流之一,因其普遍性、长久性和总量巨大等特点备受青睐。其中光伏发电是太阳能应用的一种技术,将太阳能转换为电能,利用光伏发电技术建立的分布式光伏电站应运而生,并被广泛推广,其中太阳能板为核心部件之一。分布式光伏电站的安装位置有一定的要求,必须是露天安装在室外屋顶、高空或空旷处,尽可能的接收太阳光,最大限度的发挥其光电转换性能。但是空气中的灰尘、杂质和一些腐蚀物质极易附着于太阳能板表面,一旦被雨水淋洗而且未擦干水渍,会形成大量的水痕,严重影响太阳能板光电转换效率。如果树叶、鸟粪、浮土等粘附性较强的杂物覆盖在太阳能板上,长期不做清洗工作,会出现太阳能板转换效率降低、使用寿命减小等的问题。若是太阳能板被安装在高空或者屋顶较高时,又有大雪覆盖,无法及时清理,可能会带来严重的安全隐患。With the rapid development of the world's production economy and the increasing population of the world, the non-renewable energy sources that were originally based on fossil energy are decreasing. At the same time, the ecological pollution caused by fossil energy has caused serious damage to the environment on which human beings depend. However, new energy-based energy sources have become one of the mainstream of renewable energy, and they are favored for their universality, longevity and huge total. Among them, photovoltaic power generation is a technology of solar energy application. The conversion of solar energy into electric energy, the distributed photovoltaic power station established by photovoltaic power generation technology came into being, and was widely promoted, among which solar panels are one of the core components. The installation location of distributed photovoltaic power plants has certain requirements. It must be installed in the open roof, high altitude or open space, and receive sunlight as much as possible to maximize its photoelectric conversion performance. However, dust, impurities and some corrosive substances in the air are easily attached to the surface of the solar panel. Once it is washed by the rain water and the water stain is not dried, a large amount of water marks are formed, which seriously affects the photoelectric conversion efficiency of the solar panel. If the sticky matter such as leaves, bird droppings, and floating soil is covered on the solar panel, and the cleaning work is not performed for a long time, problems such as a decrease in the conversion efficiency of the solar panel and a decrease in the service life may occur. If the solar panels are installed at high altitude or the roof is high, and there is heavy snow cover, it cannot be cleaned up in time, which may bring serious safety hazards.
现有技术中,针对分布式光伏电站的清洗装置,一种是采用清洁设备,如专利名称为:多功能太阳能电池板清洗车,申请号为:201410196364.1的专利,该专利对太阳能电池板的阵列和设计安装均有一定的限制要求,同时一块太阳能板安装一个清洁设备,成本较高、安装复杂、占地面积大;另一种是采用清扫机器人,如专利名称为:太阳能电池板清洗机器人,申请号:201610495980.6,该方法可进行 自动清洗,无需改造任何光伏组件,节约了人工费用,并且可以设定不同工作模式,配合少量水即可完成清洗工作,能够节约水资源,但是成本过高,维修费用也很高,容易破坏太阳能板表面,对于斜坡屋顶,难以进行清洗工作。另外有纳米薄膜自清洁技术,将自清洁涂层应用于太阳能电池玻璃镀膜上,典型的有二氧化钛涂层材料,有利于太阳能电池板的保洁,但是这个方法较大的问题是透明度、光催化活性等性能指标较低,且成本较高,未得到广泛应用。我国目前使用较多的仍是人工清洗,劳动强度大且工作效率低。In the prior art, for the cleaning device of the distributed photovoltaic power station, one is to use a cleaning device, such as the patent name: multi-function solar panel cleaning vehicle, the application number is: 201410196364.1, the patent for the array of solar panels There are certain restrictions on design and installation. At the same time, a solar panel is installed with a cleaning device, which has high cost, complicated installation and large floor space. The other is to use a cleaning robot, such as the patent name: solar panel cleaning robot. Application No.: 201610495980.6, this method can be used for automatic cleaning, no need to modify any PV modules, saving labor costs, and can set different working modes, with a small amount of water to complete the cleaning work, which can save water resources, but the cost is too high. Maintenance costs are also high, and it is easy to damage the surface of the solar panel. It is difficult to clean the slope roof. In addition, there is a nano-film self-cleaning technology, which applies a self-cleaning coating to the solar cell glass coating. A typical titanium dioxide coating material is beneficial to the cleaning of the solar panel, but the larger problem of this method is transparency and photocatalytic activity. Other performance indicators are lower, and the cost is higher, which has not been widely used. At present, the use of more in China is still manual cleaning, labor intensity and low work efficiency.

水分别通过长水管3和第一喷头11进入喷水区15内并会形成旋涡注水,可以将太阳能电池板100表面上的杂物去除,再从喷水口18 喷出,喷水口18呈长条缝状,喷出的水形成一层薄水幕,便于对太阳能电池板100的清洗,泄水区16可以减小喷水区15水压,多余的水进入泄水区16可从泄水口19流出。本实施例中,罩子21的弧面为96度,挡水板17的弧面为83度,水进入喷水区15内后会形成垂直涡流,垂直涡流可以对太阳能电池板100表面提供最大化的冲击力,不仅利用涡流注水节约了水资源,而且由于水流自下而上、再自上而下的二次冲洗提高了清洗效率。The water enters the water spray area 15 through the long water pipe 3 and the first spray head 11, respectively, and forms a vortex water injection, and the impurities on the surface of the solar battery panel 100 can be removed, and then sprayed from the water spray port 18, and the water spray port 18 is The strip is slit, and the sprayed water forms a thin water curtain to facilitate the cleaning of the solar panel 100. The drain area 16 can reduce the water pressure of the spray area 15, and the excess water can enter the drain area 16 to be discharged. The nozzle 19 flows out. In this embodiment, the curved surface of the cover 21 is 96 degrees, and the curved surface of the water retaining plate 17 is 83 degrees. When the water enters the sprayed area 15, a vertical eddy current is formed, and the vertical eddy current can maximize the surface of the solar panel 100. The impact force not only saves water resources by using vortex water injection, but also improves the cleaning efficiency due to the bottom-up and top-down secondary flushing of the water flow.

罩子21的两侧均安装有超声清洗装置32,本实施例中超声清洗装置32采用公告号为CN101395704B的发明装置。The ultrasonic cleaning device 32 is mounted on both sides of the cover 21. In the present embodiment, the ultrasonic cleaning device 32 uses the invention device with the publication number CN101395704B.
罩子21两侧安装有超声清洗装置32,为了避免超声清洗装置32损坏太阳能电池板100表面,保证罩子21注水后才能启动超声清洗装置32,同时超声震动清洗正是需要涡流注水,以水为媒介方能实现,超声清洗装置32的原理是利用声能转化为机械能,由于超声波的辐射,在声波的作用下使得罩子21中的注水震动,破坏太阳能电池板100表面的杂质和污物的吸附,从而剥离污物层。Ultrasonic cleaning device 32 is installed on both sides of the cover 21. In order to prevent the ultrasonic cleaning device 32 from damaging the surface of the solar panel 100, the ultrasonic cleaning device 32 can be activated after the cover 21 is filled with water, and the ultrasonic vibration cleaning requires eddy current injection, and water is used as a medium. It can be realized that the principle of the ultrasonic cleaning device 32 is to convert the acoustic energy into mechanical energy. Due to the radiation of the ultrasonic wave, the water injection in the cover 21 vibrates under the action of the sound wave, and the adsorption of impurities and dirt on the surface of the solar panel 100 is destroyed. Thereby the dirt layer is peeled off.
长水管3与卡块23之间通过滑移套设在长水管3外壁的套环31进行连接。将套环31设置为与长水管3外壁滑移连接,方便可以根据相邻两个导轨22之间的间距调整套环31的位置,使得第二喷头12能够对准导轨22,方便对导轨22的冲洗,调整第一喷头11的位置保证对太阳能电池板100表面的清洗效果。The long water pipe 3 and the block 23 are connected by a collar 31 which is slip-sleeved on the outer wall of the long water pipe 3. The collar 31 is disposed to be slidably coupled to the outer wall of the long water pipe 3, so that the position of the collar 31 can be adjusted according to the spacing between the adjacent two guide rails 22, so that the second nozzle 12 can be aligned with the guide rail 22 to facilitate the alignment of the guide rail 22. The flushing adjusts the position of the first head 11 to ensure the cleaning effect on the surface of the solar panel 100.
长水管3、第一长气管6和第二长气管9均是完整且足够长的一根管子,水箱1、第一气箱4和第二气箱7均设与室内。The long water pipe 3, the first long gas pipe 6 and the second long gas pipe 9 are both a complete and long enough pipe, and the water tank 1, the first gas tank 4 and the second gas tank 7 are both provided indoors.
