[0002] Gobi photovoltaic panels refer to solar photovoltaic panels installed in gobi desert areas. These areas usually have abundant sunlight resources and vast land areas, which are suitable for large-scale development of the photovoltaic power generation industry. Building a photovoltaic power station on the gobi beach can not only effectively utilize solar resources, reduce dependence on traditional fossil fuels, and reduce greenhouse gas emissions, but also improve the local ecological environment to a certain extent and inhibit the expansion of desertification. Photovoltaic panels are usually composed of highly efficient monocrystalline silicon or polycrystalline silicon solar cells, installed on brackets resistant to wind and sand and corrosion. These cells can convert the energy in sunlight into electrical energy, which is collected and transmitted to the power grid through the circuit system behind the photovoltaic panel. Photovoltaic power stations in gobi areas are generally equipped with energy storage systems, which can continue to supply power at night or on cloudy days to achieve 24-hour uninterrupted power supply.
[0003] When current gobi photovoltaic panels are in use, due to the harsh gobi environment with strong wind and sand, a transparent tempered glass cover is generally installed on the surface of the photovoltaic panel to prevent the surface of the photovoltaic panel from being worn by sand and easily damaged. When the transparent tempered glass cover is installed on the surface of the photovoltaic panel for use, although it does not affect the photovoltaic panel from absorbing heat and converting it into electrical energy, when there is a large amount of dust accumulated on the transparent tempered glass cover and there is no dust cleaning structure, the dust will block the sunlight from shining on the photovoltaic panel, resulting in a lower heat conversion rate of the photovoltaic panel.

[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making any creative work shall fall within the scope of protection of the present application.
[0022] The present application is described in detail below with reference to the accompanying drawings and specific implementation methods.
[0023] Example
[0024] like Figures 1 - 6As shown in the figure, a photovoltaic power generation panel for the gobi that can sweep dust includes: a photovoltaic power generation panel body 1, a protection frame 101 installed outside the photovoltaic power generation panel body 1, a transparent tempered glass cover 102 installed on the top of the photovoltaic power generation panel body 1, a support frame 2 fixedly installed at the bottom of the photovoltaic power generation panel body 1 by bolts, and a dust cleaning component arranged on one side of the outer end of the photovoltaic power generation panel body 1. The dust cleaning component includes: a cleaning box 3, a fixing block 301, an electric push rod 302, and a scraping plate 303. A power supply component is arranged on one side of the outer end of the support frame 2. The power supply component includes: a battery box 5, a storage battery 501, an inverter 502, and a photovoltaic controller 503.
[0025] Among them, installation blocks 103 are respectively installed on both sides of the bottom of the transparent tempered glass cover 102, and screw holes 104 are opened on the four sides of the top of the protection frame 101 and both sides of the top of the installation block 103. When the photovoltaic power generation panel body 1 is in use, the photovoltaic power generation panel body 1 is fixedly installed on the support frame 2 by bolts. The support frame 2 is buried in a foundation pit, and concrete is poured to fix the support frame 2 in the foundation pit to increase the stability of the support frame 2 when used in the gobi. Then, the transparent tempered glass cover 102 is placed on the surface of the photovoltaic power generation panel body 1. The installation blocks 103 on both sides of the bottom of the transparent tempered glass cover 102 are placed in contact and fit with both sides of the top of the protection frame 101, so that the screw holes 104 opened on the protection frame 101 and the installation block 103 are docked. At this time, bolts are tightened inside the screw holes 104, and then the transparent tempered glass cover 102 is fixedly installed on the surface of the photovoltaic power generation panel body 1. The thickness of the transparent tempered glass cover 102 is 1CM, so that sunlight can pass through the transparent tempered glass cover 102 and irradiate on the surface of the photovoltaic power generation panel body 1 to be heated, and it can also prevent sand and dust from getting on the surface of the photovoltaic power generation panel body 1 through the transparent tempered glass cover 102, avoiding damage to the surface of the photovoltaic power generation panel body 1 being scratched by sand.
[0026] Among them, a cleaning box 3 is installed on one side of the outer end of the photovoltaic power generation panel body 1. A fixing block 301 is installed on one side inside the cleaning box 3. One end of the fixing block 301 is fixedly installed with an electric push rod 302. One end of the electric push rod 302 is fixedly installed with a scraping plate 303. The bottom of the scraping plate 303 is flush with the surface of the transparent toughened glass cover 102, and the width of the scraping plate 303 is the same as that of the transparent toughened glass cover 102. An activity port 304 is opened on the outer end of the cleaning box 3 facing the direction of the transparent toughened glass cover 102, and the scraping plate 303 is located inside the activity port 304. When the photovoltaic power generation panel body 1 generates electricity by heating and is protected by the transparent toughened glass cover 102, when dust accumulates on the surface of the transparent toughened glass cover 102, the electric push rod 302 is started to push the scraping plate 303 to move out of the cleaning box 3 from the activity port 304. Since the bottom of the scraping plate 303 is flush with the surface of the transparent toughened glass cover 102, when the scraping plate 303 is pushed towards the transparent toughened glass cover 102, the scraping plate 303 can scrape off the dust accumulated on the surface of the transparent toughened glass cover 102, achieving the purpose of dust sweeping and cleaning, avoiding the dust blocking the sunlight from shining on the photovoltaic power generation panel body 1, and ensuring that the photovoltaic power generation panel body 1 can be normally heated and converted into electric energy for utilization.
[0027] After the electric push rod 302 pushes the scraping plate 303 to move back and forth on the surface of the transparent toughened glass cover 102 to complete the dust sweeping and cleaning, the electric push rod 302 can drive the scraping plate 303 back into the activity port 304 to seal the activity port 304 and prevent dust from entering the inside of the cleaning box 3 from the activity port 304.
[0028] Among them, heat insulation layers 4 are provided inside both the cleaning box 3 and the scraping plate 303. The heat insulation layer 4 is made of aerogel material. When the electric push rod 302 is fixedly installed inside the cleaning box 3 through the fixing block 301 for use, the cleaning box 3 and the scraping plate 303 form a closed space to hide and protect the electric push rod 302. Since heat insulation layers 4 are provided inside both the cleaning box 3 and the scraping plate 303 and the heat insulation layer 4 is made of aerogel material, the cleaning box 3 and the scraping plate 303 have good heat insulation performance, can effectively block the external heat from entering the inside of the cleaning box 3, and avoid the electric push rod 302 being easily damaged by heat in the Gobi environment.
[0029] Among them, a placement table 7 is fixedly installed on one side of the outer end of the support frame 2. A support rod 701 is fixedly installed between the placement table 7 and the support frame 2 by bolts. On both sides of the top of the placement table 7, support plates 702 are fixedly installed. A wire groove opening 703 is provided on the side of the support plate 702 close to the support frame 2. When the placement table 7 is in use, support rods 701 are installed on both sides of the outer end of the placement table 7 by bolts, and one end of the support rod 701 is installed with the support frame 2 by bolts, so that an integral body is formed among the placement table 7, the support frame 2 and the support rod 701. After the placement table 7 is installed, the bottom of the cleaning box 3 is fixedly installed on the top of the support plate 702 by bolts. The cleaning box 3 is supported by the placement table 7 and the support plate 702 to ensure the stable use of the cleaning box 3.
[0030] Among them, a battery box 5 is provided on one side of the outer end of the support frame 2. A storage battery 501 is installed inside the battery box 5. An inverter 502 is installed on one side of the storage battery 501. A photovoltaic controller 503 is installed at the top end inside the battery box 5.
[0031] When the photovoltaic power generation panel body 1 is in use, the photovoltaic power generation panel body 1 is connected to the inverter 502 and the storage battery 501 through wires. The photovoltaic controller 503 and the storage battery 501 are connected to the control chassis 6 through wires. The control chassis 6 is connected to the electric push rod 302 through wires. When sunlight shines on the photovoltaic power generation panel body 1, the photovoltaic power generation panel body 1 absorbs heat energy and converts it into electric energy. The direct current is converted into alternating current through the inverter 502. When the electric energy is stored in the storage battery 501, the photovoltaic controller 503 plays a role in protecting the transmission circuit against overcharge, over-discharge, short circuit and overload, ensuring the stability of electricity storage. After the converted electric energy is stored in the storage battery 501, the storage battery 501 can supply power to the control chassis 6 and the electric push rod 302 for use. The photovoltaic power generation structure is a mature and conventional technology in the technical field. And this solution does not make improvements to the circuit or program of the photovoltaic power generation structure. The circuit and signal connection methods among its photovoltaic power generation structures also belong to common conventional technologies. Therefore, the circuit and signal connection relationships are not described in detail.
[0032] Among them, a control chassis 6 is fixedly installed on one side of the top of the battery box 5. The control chassis 6 is composed of a timer, a control unit, an actuator and a contact. The control chassis 6 is connected to the photovoltaic controller 503 through wires. The working principles of the timer, the control unit, the actuator and the contact are as follows: Timer: used to set how long it takes for the switch to be activated. Control unit: This part is responsible for processing the information of the timer and sending a signal when the set time arrives. Actuator: When the control unit receives that the timer reaches the set time, the actuator will start. This part can be an electromagnet, a motor or any other device that can convert a signal into a mechanical action. Contact: The actuator will open or close the circuit through the contact.
[0033] When the control cabinet 6 is used to set the control time for starting and closing the electric push rod 302, since there is no sunlight at night, there is no need to set the night period. It is only necessary to set three time periods during the day for cleaning. The dust-sweeping cleaning time is 10 minutes, that is, the first time period (07:50 - 8:00), the second time period (11:50 - 12:00), and the third time period (15:50 - 16:00). During these three time periods, the control cabinet 6 will regularly start the electric push rod 302 to work. The electric push rod 302 will push the scraper 303 to move back and forth on the surface of the transparent tempered glass cover 102 for dust-sweeping cleaning. After this time period ends, the electric push rod 302 will close and stop working. Moreover, for the control program involved in the present utility model, those skilled in the art can implement it according to the same or similar principles in the prior art. This part is not the innovation of the present utility model.
[0034] Working principle:
[0035] When the photovoltaic panel body 1 is in use, the photovoltaic panel body 1 is fixedly installed on the support frame 2 through bolts. The support frame 2 is buried in the foundation pit, and concrete is poured to fix the support frame 2 in the foundation pit to increase the stability of the support frame 2 when used in the gobi. Then, the transparent tempered glass cover 102 is placed on the surface of the photovoltaic panel body 1. The mounting blocks 103 on both sides of the bottom of the transparent tempered glass cover 102 are placed in contact and fit with the top sides of both sides of the protection frame 101, so that the protection frame 101 is docked with the screw holes 104 opened on the mounting blocks 103. At this time, the bolts are tightened inside the screw holes 104, and then the transparent tempered glass cover 102 is fixedly installed on the surface of the photovoltaic panel body 1. The thickness of the transparent tempered glass cover 102 is 1CM, so that sunlight can pass through the transparent tempered glass cover 102 and irradiate on the surface of the photovoltaic panel body 1 to be heated, and it can also prevent dust from falling on the surface of the photovoltaic panel body 1 through the transparent tempered glass cover 102, avoiding damage to the surface of the photovoltaic panel body 1 by being scratched by sand.
[0036] When dust accumulates on the surface of the transparent tempered glass cover 102, the electric push rod 302 is started to push the scraper 303 to move out of the cleaning box 3 from the movable opening 304. Since the bottom of the scraper 303 is flush with the surface of the transparent tempered glass cover 102, when the scraper 303 is pushed towards the transparent tempered glass cover 102, the scraper 303 can scrape off the dust accumulated on the surface of the transparent tempered glass cover 102, achieving the purpose of dust-sweeping cleaning, avoiding dust blocking sunlight from irradiating on the photovoltaic panel body 1, and ensuring that the photovoltaic panel body 1 can be normally heated and converted into electrical energy for utilization.
