Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic support technology, specifically relating to a protective device for rooftop photovoltaic panels. Background Technology

[0002] Solar panels are often installed on rooftops and are subject to various natural and human-induced factors during use. Natural factors include hail, heavy rain, strong winds, ultraviolet radiation, as well as dust accumulation and snow buildup; human-induced factors include potential unintentional collisions or deliberate damage. To address these issues, protective devices are essential to ensure the normal operation of solar panels.

[0003] However, most photovoltaic panel protection devices currently on the market have relatively simple structures. Their functions are mainly limited to protecting the edges of the photovoltaic panels, reducing damage from collisions and abrasions, and enhancing the overall structural strength of the photovoltaic panels, thus reducing the risk of panel breakage due to external forces to some extent. However, when debris or snow accumulates on the surface of the photovoltaic panels, these obstructions can seriously affect the absorption and conversion efficiency of solar energy. To address such issues, frequent manual cleaning of the photovoltaic panel surface is often required, which is cumbersome and places a heavy workload on maintenance personnel. Utility Model Content

[0004] The purpose of this invention is to provide a rooftop photovoltaic panel protection device to solve the problems existing in the background art.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0006] A rooftop photovoltaic panel protection device, comprising:

[0007] Connecting plate, used to connect other components;

[0008] Two clamping plates are installed on the outside of the connecting plate and are symmetrically arranged on the connecting plate;

[0009] Four side plates are symmetrically fixedly connected to the two sides of the clamping plate, and the included angle between the two side plates on the same clamping plate is set to an obtuse angle. The two side plates on the same clamping plate and the other two side plates are provided with mounting grooves at their opposite ends for installing other components.

[0010] A plurality of mounting strips are provided, each of which is located between two clamping plates and is fixedly connected to the side plate on both sides. Each of the mounting strips is located below the mounting groove. Each mounting strip has a plurality of mounting holes on its surface for mounting a photovoltaic panel.

[0011] Two protective plates are respectively located between the two clamping plates, and the two sides of the two protective plates are rotatably connected to the inside of the mounting groove. The rotatable connection point between the protective plates and the mounting groove is located in the middle of the side plate.

[0012] A cleaning component is located below the two protective plates and is used to work with the protective plates to achieve the purpose of cleaning.

[0013] Further specifying, the cleaning component includes:

[0014] A servo motor, mounted on the outside of any of the clamps, is used to provide power during cleaning;

[0015] Two transmission rods are located between two clamping plates and are symmetrically rotatably connected to the two clamping plates. One end of each transmission rod extending out of the clamping plate is fixedly connected to the output shaft of the servo motor.

[0016] A transmission gear is fixedly connected to one end of the transmission rod that extends out of the clamp, and the transmission gear is positioned opposite to the servo motor.

[0017] The driven gear is fixedly connected to one end of the other transmission rod that extends out of the clamp, and meshes with the transmission gear.

[0018] Several cams are provided, each of which is fixed to the outside of the two transmission rods, and the arc-shaped surface of the cam abuts against the lower end of the corresponding protective plate.

[0019] Furthermore, the cams on the outer sides of the two drive rods are arranged alternately.

[0020] Furthermore, each of the mounting slots has a groove on its lower wall, and each groove is close to the connecting plate. An elastic rubber strip connects the groove to the protective plate.

[0021] Further specified, a crossbar is fixed between the two symmetrical side plates, and the two crossbars are located between the two clamping plates. The two crossbars are located on the side away from the connecting plate and are symmetrical about the connecting plate as the axis of symmetry.

[0022] Furthermore, the connecting plate is V-shaped, and the included angle of the V-shape is obtuse.

[0023] Furthermore, the lower end of the side plate is fixed with two support rods, and the two support rods are symmetrical about the connecting plate as an axis of symmetry.

[0024] The beneficial effects of this utility model are:

[0025] 1. Through the cooperation of the clamps, side plates, connecting plates and protective plates, a stable protective frame is constructed, which facilitates all-round protection of the photovoltaic panels installed on the mounting strip.

[0026] 2. By setting up a servo motor, transmission rod, transmission gear, driven gear and cam, the cam rotates and lifts the protective plate to tilt it. Gravity is used to shake off debris and snow, reducing the frequency and workload of manual cleaning. At the same time, the elastic rubber strip stretches and stores energy when the protective plate rotates. After the cam leaves, it retracts and the protective plate automatically resets, ensuring the continuity of the cleaning action.

[0027] 3. By setting up crossbars, the protective plate is tapped when it rotates to a specific position, causing it to vibrate and making the cleaning more thorough and efficient. Attached Figure Description

[0039] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0040] Example 1:

[0041] like Figures 1-6 As shown, a rooftop photovoltaic panel protection device includes:

[0042] Connecting plate 100 is used to connect other components;

[0043] Two clamping plates 101 are installed on the outside of the connecting plate 100 and are symmetrically arranged on the connecting plate 100.

[0044] Four side plates 102 are symmetrically fixed to the two sides of two clamping plates 101 respectively, and the included angle between the two side plates 102 on the same clamping plate 101 is set to an obtuse angle. The two side plates 102 on the same clamping plate 101 and the other two side plates 102 are provided with mounting grooves 103 at the opposite ends for installing other components.

[0045] Several mounting strips 104 are located between two clamping plates 101, and both sides of each mounting strip 104 are fixedly connected to the side plate 102. Each mounting strip 104 is located below the mounting groove 103. Several mounting holes 105 are opened on the surface of any mounting strip 104 for mounting photovoltaic panels.

[0046] Two protective plates 106 are located between two clamping plates 101, and the two sides of the two protective plates 106 are rotatably connected to the inside of the mounting groove 103. The rotatable connection point between the protective plates 106 and the mounting groove 103 is located in the middle of the side plate 102.

[0047] The cleaning component is located below the two protective plates 106 and is used to work with the protective plates 106 to achieve the purpose of cleaning.

[0048] The connecting plate 100 provides the foundation for the connection of the entire protective device, enabling the components to be combined into an organic whole.

[0049] The clamping plate 101 is used to assist the connecting plate 100 in clamping and fixing the entire device on the roof, and also serves as a connecting component for the side plate 102.

[0050] The side plate 102, on the one hand, cooperates with the clamping plate 101 to further fix the device on the roof, and on the other hand, cooperates with the connecting plate 100 and the clamping plate 101 to form a protective frame structure.

[0051] The included angle between the two side panels 102 is set to an obtuse angle, which can better fit the roof and also prevent excessive debris and snow from accumulating on the upper side, thus affecting subsequent cleaning.

[0052] The mounting strip 104 is used to provide a carrier for the installation of photovoltaic panels. Together with the mounting holes 105, the photovoltaic panels can be fixed in an orderly manner inside the protective device.

[0053] The protective plate 106, together with the connecting plate 100, the clamping plate 101 and the side plate 102, forms a protective frame that can protect the internal photovoltaic panels. At the same time, the protective plate 106 can rotate and tilt inside the mounting groove 103, so that impurities and snow falling onto the upper surface of the protective plate 106 can slide off, thereby reducing the absorption of sunlight by the photovoltaic panels.

[0054] Each of the two protective plates 106 has a rubber sealing strip at one end facing the other. This not only prevents debris from entering the device and falling onto the photovoltaic panel, thus affecting it, but also reduces the impact between the two protective plates 106.

[0055] The cleaning component provides power and mechanical transmission for the cleaning action of the protective plate 106, enabling the protective plate 106 to move according to design requirements, shaking off debris and snow from the surface, thereby achieving the purpose of cleaning.

[0056] The connecting plate 100 serves as the core of the connection, enabling the clamping plate 101 and the side plate 102 to be connected in an orderly manner, forming a stable frame structure. The clamping plate 101 and the side plate 102 cooperate with each other, not only fixing the mounting strip 104, but also providing support for the installation and rotation of the protective plate 106. The mounting strip 104 supports the photovoltaic panel, ensuring that it is firmly installed. The protective plate 106 and the cleaning component work together to protect the photovoltaic panel while also realizing an automatic cleaning function, reducing the frequency and workload of manual cleaning, and improving the overall protection effect and usage efficiency of the photovoltaic panel.

[0057] The cleanup components include:

[0058] Servo motor 200, mounted on the outside of any clamp 101, is used to provide power during cleaning;

[0059] Two transmission rods 201 are located between two clamping plates 101 and are symmetrically rotatably connected to the two clamping plates 101. One end of any transmission rod 201 extending out of the clamping plate 101 is fixedly connected to the output shaft of the servo motor 200.

[0060] The transmission gear 202 is fixedly connected to one end of the transmission rod 201 that extends out of the clamp 101, and the transmission gear 202 is arranged opposite to the servo motor 200.

[0061] Driven gear 203 is fixedly connected to one end of another transmission rod 201 that extends out of clamp 101, and meshes with transmission gear 202;

[0062] Several cams 204 are fixed to the outside of two transmission rods 201, and the arc-shaped surface of the cam 204 abuts against the lower end of the corresponding protective plate 106.

[0063] Servo motor 200 is the power source for the entire cleaning assembly.

[0064] The transmission rod 201 serves to transmit power and support the cam 204. One end of one transmission rod 201 is fixedly connected to the output shaft of the servo motor 200. When the servo motor 200 rotates, it drives the transmission rod 201 connected to it to rotate synchronously. Since the two transmission rods 201 are interconnected through the transmission gear 202 and the driven gear 203, the other transmission rod 201 can also rotate, thus realizing the relative rotation of the two transmission rods 201. At the same time, the transmission rod 201 provides a mounting position for the cam 204 fixed on its outer side, ensuring that the cam 204 can rotate with the rotation of the transmission rod.

[0065] The transmission gear 202 and the driven gear 203 utilize the characteristics of gear transmission to transmit the rotation of one transmission rod 201 to another transmission rod 201, enabling the two transmission rods 201 to rotate relative to each other. Ideally, the two transmission rods 201 rotate in opposite directions but at the same speed. This design allows the cams 204 on the two transmission rods 201 to work in coordination, ensuring that the cleaning action on the two protective plates 106 is synchronous and stable.

[0066] The cam 204, designed in a teardrop shape, rotates to its tip position and abuts against the protective plate 106. As the cam 204 continues to rotate, the upward thrust at the tip gradually increases, pushing the protective plate 106 around the rotational connection point with the mounting groove 103. Because the protective plate 106 is rotatably connected to the inside of the mounting groove 103 on both sides, and the connection point is located in the middle of the side plate 102, the protective plate 106 will rotate around this connection point as an axis under the pushing action of the cam tip, thereby causing the upper surface of the protective plate 106 to tilt. This change in tilt angle, utilizing the principle of gravity, causes debris and snow on the upper surface of the protective plate 106 to slide down along the tilted surface, achieving the purpose of cleaning the protective plate. Moreover, the teardrop-shaped profile of the cam 204 makes the lifting and lowering process of the protective plate 106 smoother, avoiding debris splashing or damage to the protective plate due to sudden movements. During one revolution of cam 204, the protective plate 106 will undergo a complete motion of lifting, tilting, and falling back, completing one cleaning operation. This cycle is repeated to achieve continuous cleaning of the protective plate.

[0067] The servo motor 200 provides power, which is transmitted to the cam 204 through the transmission rod 201. At the same time, the transmission gear 202 and the driven gear 203 ensure that the two transmission rods 201 rotate in a coordinated manner, so that each cam 204 can synchronously and stably lift the protective plate 106. When the servo motor 200 starts, it drives the transmission rod 201 to rotate, and the cam 204 on the transmission rod 201 rotates accordingly, gradually lifting the protective plate 106, changing its tilt angle, and cleaning away the debris and snow on the protective plate 106. The entire cleaning process is highly automated, requiring no frequent manual operation, which greatly improves the cleaning efficiency, ensures the light-gathering effect of the photovoltaic panel, and ensures that the photovoltaic panel can work continuously and stably.

[0068] The cams 204 on the outer sides of the two transmission rods 201 are arranged alternately.

[0069] During rotation, the alternating cams 204 cooperate with each other to lift the protective plate 106 in sequence, so that the protective plate 106 can smoothly change its tilt angle, thus effectively cleaning the debris and snow on the surface of the protective plate 106. This combination not only improves the cleaning efficiency, but also ensures the stability of the cleaning process, avoiding damage to the protective plate 106 or incomplete cleaning due to uncoordinated movement of the cams 204, and effectively ensuring the normal operation of the cleaning function of the photovoltaic panel protection device.

[0070] Each mounting slot 103 has a groove 300 on its lower wall, and each groove 300 is close to the connecting plate 100. An elastic rubber strip 301 connects the groove 300 and the protective plate 106.

[0071] The groove 300 provides space for the installation and placement of the elastic rubber strip 301, so that the elastic rubber strip 301 can be stably connected between the mounting groove 103 and the protective plate 106; the groove 300 is located close to the connecting plate 100 and the cam 204, and this layout can better utilize the elastic force of the elastic rubber strip 301.

[0072] The elastic rubber strip 301, based on the excellent elastic properties of rubber, connects the groove 300 and the protective plate 106. The protective plate 106 rotates around its connection point with the mounting groove 103, stretching the elastic rubber strip 301. During this stretching process, the elastic rubber strip 301 stores elastic potential energy, much like a stretched spring. When the cam 204 no longer pushes the protective plate 106, the elastic rubber strip 301 returns to its original shape using its stored elastic potential energy. The resulting tension pulls the protective plate 106 back to its initial position, preparing for the next cleaning cycle. This elastic restoring force ensures the continuity of the cleaning action of the protective plate 106 and its automatic reset function.

[0073] A crossbar 302 is fixed between the two symmetrical side plates 102, and the two crossbars 302 are located between the two clamping plates 101. The two crossbars 302 are located on the side away from the connecting plate 100 and are symmetrical about the connecting plate 100 as the axis of symmetry.

[0074] The crossbar 302 has a certain rigidity, which enhances the structural stability of the entire protective device. At the same time, when the protective plate 106 rotates to a specific position during the cleaning process, it will strike the crossbar 302. After the crossbar 302 is struck, the protective plate 106 will vibrate. This vibration can accelerate the sliding of debris and snow on the protective plate, further improving the cleaning effect. Moreover, the symmetrical arrangement of the crossbars 302 ensures that the striking and vibration effects on both sides of the protective plate 106 are consistent, preventing a situation where one side has a better cleaning effect and the other side has a poor cleaning effect, thus ensuring the comprehensiveness and efficiency of the cleaning work.

[0075] The connecting plate 100 is V-shaped, and the included angle of the V-shape is obtuse.

[0076] The connecting plate 100 is located on the upper side of the entire device and is installed in an inverted V shape. It allows snow, rainwater and other debris falling on the connecting plate 100 to slide to both sides, thereby preventing the accumulation of debris on the device and affecting the normal use of the photovoltaic panels.

[0077] Two support rods 303 are fixed at the lower end of the side plate 102, and the two support rods 303 are symmetrical about the connecting plate 100 as the axis of symmetry.

[0078] The support rod 303 is used to abut against the roof to prevent the roof from affecting the operation of the internal components of the device after it is installed on the roof; the support rod 303 can also share some of the pressure and enhance the stability of the protective device when installed on the roof.

[0079] When there is debris or snow on the upper part of the protective plate 106:

[0080] When the servo motor 200 is started, the output shaft of the servo motor 200 drives the transmission rod 201 to rotate. Since the transmission gear 202 and the driven gear 203 mesh with each other, the two transmission rods 201 rotate synchronously. As a result, each cam 204 will also rotate synchronously. The rotating cam 204 will push up the protective plate 106, causing the upper surface of the protective plate 106 to gradually tilt. The tilted protective plate 106 uses gravity to make debris and snow slide off along the tilted surface, thus achieving cleaning.

[0081] The cam 204 is teardrop-shaped, and initially, the arc surface of the cam 204 is in contact with the protective plate 106. Therefore, when it rotates to the tip position and abuts against the lower end of the protective plate 106, continued rotation will increase the upward thrust of the tip, thereby causing the protective plate 106 to tilt.

[0082] During the rotation of cam 204;

[0083] The elastic rubber strip 301 is stretched and stores elastic potential energy. When the cam 204 rotates away from the position of lifting the protective plate 106, the elastic rubber strip 301 contracts with the stored elastic potential energy, pulling the protective plate 106 back to the initial position, preparing for the next cleaning and ensuring the continuity of the cleaning action.

[0084] When the protective plate 106 rotates to a specific position, it will strike the crossbar 302, causing the protective plate 106 to vibrate. This vibration can accelerate the sliding off of residual debris and snow on the protective plate 106, further improving the cleaning effect. In addition, since the two crossbars 302 are symmetrical about the connecting plate 100, the striking and vibration effects on both sides of the protective plate 106 are consistent, ensuring that the cleaning work is comprehensive and efficient.

[0085] In this embodiment, by starting the servo motor 200, the transmission rod 201 and the cam 204 are driven to rotate synchronously, and the protective plate 106 is lifted up, so that the upper surface of the protective plate 106 is tilted, thereby using gravity to clean the debris and snow on the protective plate 106. During the rotation of the protective plate 106, the elastic rubber strip 301 stretches and stores energy when the protective plate 106 rotates. After the cam 204 leaves, it contracts to reset the protective plate 106, preparing for the next cleaning. When the protective plate 106 rotates to a specific position, it will strike the crossbar 302 to generate vibration, which will accelerate the sliding of residual debris and snow.

[0086] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
