Technical Field

[0001] The utility model relates to the field of photovoltaic power generation, in particular to a photovoltaic component capable of eliminating reflection effects. Background Art

[0002] One of the most important issues in the world in this century is the problem of climate and environmental pollution. With the rapid development of the economy and the continuous growth of the population, non-renewable resources have begun to decrease. As one of the most abundant and clean renewable energy sources, the effective development and utilization of solar energy has always been a hot topic in the world. The efficient use of solar energy has always been an important part of the future development of science and technology, thus giving rise to many photovoltaic technologies.

[0003] In the process of energy conversion, the loss of light energy caused by surface reflection in traditional photovoltaic modules is still a problem that needs to be solved in the current photovoltaic industry and is also the goal pursued by researchers in related industries. To this end, we proposed a photovoltaic module that can eliminate the reflection effect. Utility Model Content

[0004] The utility model aims to solve the technical problem of light energy loss caused by surface reflection during energy conversion of traditional photovoltaic components.

[0005] The new technical solution adopted by the utility model to solve its technical problems is:

[0006] A photovoltaic module capable of eliminating the reflective effect comprises: a photovoltaic module body, four photovoltaic panels, four hydrophobic films, four anti-reflective films, four cleaning mechanisms, a bracket, a photosensitive sensor, four drive motors, a thermomotor, a heat-conducting hose, and a controller. The photovoltaic module body is a box structure and is arranged on the ground. The four photovoltaic panels are arranged horizontally, arranged above the photovoltaic module body, and evenly arranged around the center of the photovoltaic module body. One side of the four photovoltaic panels is close to the side of the center of the photovoltaic module body, and is connected to the edge of the top plate of the photovoltaic module body through a rotating shaft. The axis of the rotating shaft is arranged horizontally, and the four photovoltaic panels form a cross shape. The four anti-reflective films are respectively arranged above the four photovoltaic panels and are respectively fixedly connected to the upper surfaces of the four photovoltaic panels. The four hydrophobic films are respectively fixedly connected to the upper surfaces of the four anti-reflective films. The four cleaning mechanisms are respectively arranged above the four hydrophobic films, and the four cleaning mechanisms are respectively connected to the four hydrophobic films in a sliding manner along the long direction of the four photovoltaic panels. The four drive motors are arranged above the photovoltaic module body and are respectively connected to the rotating shafts of the four photovoltaic panels. The photosensitive sensor is arranged on the upper part of the photovoltaic module body and is fixedly connected to the photovoltaic module body. One side of the bracket is arranged above the ground, and the other side is arranged on the side of the photovoltaic module body. One side of the bracket is fixedly connected to the ground, and the other side of the bracket is fixedly connected to the photovoltaic module body. The thermomotor is arranged inside the photovoltaic module body, passes through the side of the photovoltaic module body, contacts with four photovoltaic panels, and is electrically connected to the photosensitive sensor. One end of the heat-conducting hose is fixedly connected to the four photovoltaic panels, and the other end is fixedly connected to the thermomotor. The controller is arranged inside the photovoltaic module body, passes through the side of the photovoltaic module body, is close to the thermomotor, is fixedly connected to the photovoltaic module body, and is electrically connected to the four drive motors and the four photovoltaic panels.

[0007] When sunlight shines on the photovoltaic panel, most of the sunlight is converted into electrical energy by the photovoltaic panel, and a small part of the sunlight causes the photovoltaic panel to generate heat. The heat is transferred to the thermomotor through the thermal hose, and the thermomotor can convert the heat into electrical energy. When the photosensitive sensor detects that the photovoltaic panel has strong light intensity, it will transmit the signal of strong light intensity of the photovoltaic panel to the controller. The controller receives this signal and starts to use the current generated by the thermomotor. The generated current starts to drive the drive motor to rotate, thereby controlling the photovoltaic panel to rotate up and down along the horizontal axis. The cleaning mechanism on the photovoltaic panel will clean the upper surface of the hydrophobic film due to the rotation of the photovoltaic panel, keeping the photovoltaic panel clean. The setting of the anti-reflective film can fundamentally reduce the reflection on the surface of the photovoltaic panel.

[0008] Furthermore, graphene powder is arranged inside the heat-conducting hose, which is a heat-conducting material and can conduct the heat of the photovoltaic panel into the thermomotor through heat conduction.

[0009] When the photovoltaic panel generates heat, the heat will enter the thermal hose and be transferred to the graphene powder inside. The temperature of the graphene powder will rise, and due to its good heat transfer properties, the graphene powder will eventually transfer the heat to the thermomotor.

[0010] Furthermore, the four hydrophobic films are respectively fixedly connected to the upper surfaces of the four anti-reflective films by glue.

[0011] The connection of glue can ensure the firmness between the hydrophobic film and the anti-reflective film. When foreign objects fall on the hydrophobic film, they will not enter between the hydrophobic film and the anti-reflective film, and affect the anti-reflective effect of the anti-reflective film.

[0012] Furthermore, two linear grooves are respectively arranged on the side edges of the photovoltaic panel surface, and the linear grooves are arranged along the length direction of the panel.

[0013] To ensure that the cleaning mechanism can slide fixedly along a straight line on the photovoltaic panel, a sliding groove is required on the photovoltaic panel for the cleaning mechanism to slide. When sliding under the action of gravity, due to the two linear grooves respectively set on the sides of the photovoltaic panel surface, the cleaning mechanism can efficiently clean the hydrophobic film on the upper surface of the photovoltaic panel without sliding off the photovoltaic panel.

[0014] Furthermore, each cleaning mechanism includes two slide rails and a cleaning brush. The two slide rails are respectively arranged inside the linear grooves on the sides of the upper surface of the corresponding photovoltaic panel and are fixedly connected to the corresponding photovoltaic panel body. The cleaning brush is strip-shaped, perpendicular to the two slide rails, located above the corresponding photovoltaic panel body, in contact with the hydrophobic film, and slidably connected to the two slide rails, and its sliding direction is parallel to the two slide rails.

[0015] When the photovoltaic panel rotates horizontally, the cleaning brush slides on the rail under the action of gravity. Since the cleaning brush is perpendicular to the photovoltaic panel, it will take away the dust on the hydrophobic film. After rainy weather, it can also wipe the rainwater on the surface of the hydrophobic film, so that the photovoltaic panel has a better sunlight absorption effect.

[0016] Furthermore, the photovoltaic panel is provided with a first baffle and a second baffle, both of which are parallel to the cleaning brush, respectively at the two side edges of the top, and are fixedly connected to the photovoltaic panel.

[0017] When the photovoltaic panel is driven to rotate upward by the rotation of the driving motor, the cleaning brush starts to slide downward under the action of gravity to clean. When it slides to the side edge of the photovoltaic panel, the second baffle will block the cleaning brush. When the photovoltaic panel is driven to rotate downward by the rotation of the driving motor, the cleaning brush starts to move away from the second baffle and eventually slides to the other side edge of the photovoltaic panel and is blocked by the first baffle. This cycle repeats to achieve the effect of automatic cleaning.

[0018] The main beneficial effects of this utility model patent are reflected in the following aspects:

[0019] 1. The energy conversion efficiency of photovoltaic modules is improved through unique optical design and structural optimization. The rotation mechanism and cleaning mechanism of the photovoltaic panel ensure that the photovoltaic panel always maintains the best angle and clean state, so as to maximize the absorption of solar energy and convert it into electrical energy. The setting of anti-reflective film can fundamentally reduce the reflection on the surface of the photovoltaic panel and improve the light capture efficiency of the photovoltaic module.

[0020] 2. Through the thermoelectric machine, the heat generated by the photovoltaic modules during operation can be effectively utilized, which not only improves the working efficiency of the photovoltaic modules, but also avoids problems such as performance degradation and shortened life due to overheating, and ensures the stability of the photovoltaic modules.

[0021] 3. The hydrophobic film on the cleaning mechanism and the anti-reflective film can effectively ensure the cleanliness of the surface of the photovoltaic module, thereby greatly reducing the manual cleaning cost, and the energy conversion efficiency of the photovoltaic module will not be affected by external dirt.

[0026] In order to make the present invention easy to understand, the concept of the present invention and the technical effects produced are further clearly and completely described below in combination with specific implementation methods, so as to fully understand the purpose, characteristics and effects of the present invention.

[0027] like Figure 1-3As shown, a photovoltaic module capable of eliminating the reflective effect comprises: a photovoltaic module body 1, four photovoltaic panels 2, four cleaning mechanisms, a bracket 3, a photosensitive sensor 4, four driving motors 5, a thermal motor 6, a heat-conducting hose 7, a controller 8, four hydrophobic films 9, and four anti-reflective films 10. The photovoltaic module body 1 is a box structure, which is arranged on the ground. The four photovoltaic panels 2 are arranged horizontally, arranged above the photovoltaic module body 1, and evenly arranged around the center of the photovoltaic module body 1. One side of the four photovoltaic panels 2 is close to the side of the center of the photovoltaic module body 1, and is connected to the top plate edge of the photovoltaic module body 1 through a rotating shaft. The axis of the rotating shaft is arranged horizontally, and the four photovoltaic panels 2 form a cross shape. The four anti-reflective films 10 are respectively arranged above the four photovoltaic panels 2 bodies, and are respectively fixedly connected to the upper surfaces of the four photovoltaic panels 2 bodies. The four hydrophobic films 9 are respectively fixedly connected to the upper surfaces of the four anti-reflective films 10. The four cleaning mechanisms are respectively arranged above the hydrophobic films 9, and the four cleaning mechanisms are respectively connected to the four hydrophobic films 9 along the board length direction of the four photovoltaic panels 2. Four driving motors 5 are arranged above the photovoltaic module body 1 and are respectively connected to the rotating shafts of the four photovoltaic panels 2. The photosensitive sensor 4 is arranged on the upper part of the photovoltaic module body 1 and is fixedly connected to the photovoltaic module body 1. One side of the bracket 3 is arranged above the ground, and the other side is arranged on the side of the photovoltaic module body 1. One side of the bracket 3 is fixedly connected to the ground, and the other side of the bracket 3 is fixedly connected to the photovoltaic module body 1. The thermomotor 6 is arranged inside the photovoltaic module body 1, passes through the side of the photovoltaic module body 1, contacts with the four photovoltaic panels 2, and is electrically connected to the photosensitive sensor 4. One end of the heat-conducting hose 7 is fixedly connected to the four photovoltaic panels 2, and the other end is fixedly connected to the thermomotor 6. The controller 8 is arranged inside the photovoltaic module body 1, passes through the side of the photovoltaic module body 1, is close to the thermomotor 6, is fixedly connected to the photovoltaic module body 1, and is electrically connected to the four driving motors 5 and the four photovoltaic panels 2.

[0028] When sunlight shines on the photovoltaic panel 2, most of the sunlight is converted into electrical energy by the photovoltaic panel 2, and a small part of the sunlight causes the photovoltaic panel 2 to generate heat, which is transferred to the thermomotor 6 through the heat-conducting hose 7, and the thermomotor 6 can convert the heat into electrical energy. When the photosensitive sensor 4 detects that the light intensity of the photovoltaic panel 2 is strong, it will transmit the signal of the strong light intensity of the photovoltaic panel 2 to the controller 8. After receiving this signal, the controller 8 starts to use the current generated by the thermomotor 6, and the generated current starts to drive the drive motor 5 to rotate, thereby controlling the photovoltaic panel 2 to rotate up and down along the horizontal axis. The cleaning mechanism on the photovoltaic panel 2 will clean the upper surface of the hydrophobic film 9 due to the rotation of the photovoltaic panel 2, keeping the photovoltaic panel 2 clean, and the setting of the anti-reflective film 10 can fundamentally reduce the reflection on the surface of the photovoltaic panel 2.

[0029] The heat-conducting hose 7 is provided with graphene powder inside, which is a heat-conducting material and can conduct the heat of the photovoltaic panel 2 into the thermomotor 6 through heat conduction.

[0030] When the photovoltaic panel 2 generates heat, the heat will enter the heat-conducting hose 7 and be transferred to the graphene powder inside. The temperature of the graphene powder will rise. Due to its own good heat transfer properties, the graphene powder will eventually transfer the heat to the thermomotor 6.

[0031] The four hydrophobic films 9 are respectively fixedly connected to the upper surfaces of the four anti-reflective films 10 by glue.

[0032] The connection of glue can ensure the firmness between the hydrophobic film 9 and the anti-reflective film 10 . When foreign objects fall on the hydrophobic film 9 , they will not enter between the hydrophobic film 9 and the anti-reflective film 10 to affect the anti-reflective effect of the anti-reflective film 10 .

[0033] Two linear grooves 11 are respectively arranged on the side edges of the surface of the photovoltaic panel 2 , and the linear grooves 11 are arranged along the length direction of the panel.

[0034] To ensure that the cleaning mechanism can slide fixedly along a straight line on the photovoltaic panel 2, a slide groove for the cleaning mechanism to slide is required on the photovoltaic panel 2. When sliding under the action of gravity, due to the two linear grooves 11 respectively set on the side edges of the photovoltaic panel 2, the cleaning mechanism can efficiently clean the hydrophobic film 9 on the upper surface of the photovoltaic panel 2 without sliding off the photovoltaic panel 2.

[0035] Each cleaning mechanism includes two slide rails 12 and a cleaning brush 13. The two slide rails are respectively arranged inside the linear grooves 11 on the side of the upper surface of the corresponding photovoltaic panel 2 and are fixedly connected to the main body of the corresponding photovoltaic panel 2. The cleaning brush 13 is strip-shaped, perpendicular to the two slide rails 12, located above the corresponding photovoltaic panel 2, in contact with the hydrophobic film 9, and slidably connected to the two slide rails 12, and its sliding direction is parallel to the two slide rails 12.

[0036] When the photovoltaic panel 2 rotates in the horizontal direction, the cleaning brush 13 slides on the slide rail 12 under the action of gravity. Since the cleaning brush 13 is perpendicular to the photovoltaic panel 2, the cleaning brush 13 will take away the dust on the hydrophobic film 9. After rainy weather, the rainwater on the surface of the hydrophobic film 9 can be wiped off, so that the photovoltaic panel 2 has a better sunlight absorption effect.

[0037] It should be noted that the utility model is a photovoltaic module that can eliminate the reflection effect. The materials of the four photovoltaic panels 2 are exactly the same, and each photovoltaic panel 2 can work independently through the drive motor 5. The sunlight intensity at different angles is different at different times of the day. When the photosensitive sensor 4 detects that the sunlight intensity at an angle is strong, it will transmit the signal of the strong sunlight intensity to the controller 8, and the controller 8 will drive the four drive motors 5 to approach the angle. A part of the thermal motor 6 and the controller 8 are exposed on all four sides of the photovoltaic module body 1, which is convenient for the connection of the heat-conducting hose 7, the drive motor 5 and each photovoltaic panel 2.

[0038] The photovoltaic panel 2 generates heat during operation, which is transferred to the thermomotor 6 through the heat-conducting hose 7, and the thermomotor 6 converts the heat into electrical energy. The thermomotor 6 can reduce the temperature of the photovoltaic panel 2 and improve the utilization rate of energy.

[0039] The cleaning mechanism on the photovoltaic panel 2 is combined with the hydrophobic film 9, which has a simple structure, is economical and practical, and does not require manual operation. It can always keep the surface of the photovoltaic panel 2 brand new, making the light energy conversion of the utility model stable and more durable.

[0040] Working principle:

[0041] Under sunlight, the photovoltaic panel 2 first absorbs solar energy and converts it into electrical energy. Since part of the sunlight is converted into heat, the temperature of the photovoltaic panel 2 rises. At this time, the thermomotor 6 starts to work, and the heat transferred by the heat-conducting hose 7 converts the heat energy into electrical energy. The graphene powder filled in the heat-conducting hose 7 serves as an efficient heat-conducting material, which helps to transfer heat to the thermomotor 6 faster.

[0042] The light sensor 4 detects the light intensity of the photovoltaic panel 2 and sends the information to the controller 8. When the light intensity exceeds the preset threshold, the controller 8 activates the thermomotor 6, and the generated electric energy drives the four drive motors 5 to rotate, thereby driving the photovoltaic panel 2 to rotate up and down along the horizontal axis. This rotation enables the cleaning brush 13 to slide on the slide rail 12 along the linear groove 11 on the surface of the photovoltaic panel 2, thereby effectively removing dust and dirt on the hydrophobic film 9, as well as water droplets after rainy weather.

[0043] In addition, the anti-reflective film 10 covers the photovoltaic panel 2, further reducing the reflection of light and improving the overall performance of the photovoltaic module. The entire system is designed to optimize the power generation performance of the photovoltaic module, extend its service life, and reduce maintenance costs through automated cleaning and heat management.

[0044] The four photovoltaic panels 2 are provided with a first baffle 14 and a second baffle 15 . The first baffle 14 and the second baffle 15 are parallel to the cleaning brush 13 , respectively at the two side edges of the top, and are fixedly connected to the photovoltaic panel 2 bodies.

[0045] When the photovoltaic panel 2 is driven to rotate upward by the rotation of the driving motor 5, the cleaning brush 13 starts to slide downward to clean under the action of gravity, and when it slides to the side edge of the photovoltaic panel 2, the second baffle 15 will block the cleaning brush 13. When the photovoltaic panel 2 is driven to rotate downward to a horizontal angle by the rotation of the driving motor 5 and continues to rotate, the cleaning brush 13 starts to move away from the second baffle 15, and finally slides to the other side edge of the photovoltaic panel 2 and is blocked by the first baffle 14, and the cycle is repeated to achieve the effect of automatic cleaning.

[0046] The core concept of the utility model lies in its innovative design and advantages, which have been explained in the foregoing content. However, it should be emphasized that these are only examples of specific implementation schemes and do not represent all possibilities of the utility model. Professionals in the technical field should recognize that the application and implementation of the utility model have a certain flexibility, allowing adjustments and optimizations without violating its basic principles. Various modifications and improvements can be made to it according to actual needs. The scope of protection of the utility model shall be based on the attached claims and their equivalents.
