Technical Field

[0001] The utility model relates to the technical field of photovoltaic equipment, in particular to a sunshade. Background Art

[0002] Awnings are widely used in outdoor facilities to provide shelter and protect people and objects from the direct impact of strong sunlight and rain. With the increasing awareness of the use of renewable energy, photovoltaic panels are integrated into awnings as a green energy technology. This type of awning not only has the dual functions of shading and rain protection, but also can convert solar energy into electrical energy to achieve energy self-sufficiency.

[0003] In the related art, photovoltaic panels in awnings are usually fixedly mounted on brackets to cover a specific area. However, fixed photovoltaic panels are prone to water accumulation in rainy weather. As the water accumulates, the effective receiving area of ​​the photovoltaic panels decreases, thereby reducing the photoelectric conversion efficiency of the photovoltaic panels.

[0033] See also Figure 1 and Figure 2 The sunshade 100 of the embodiment of the utility model comprises a bracket 10, a photovoltaic panel 20 and a driving device 30. The bracket 10 is formed with a water receiving groove 11; the photovoltaic panel 20 is arranged on the bracket 10; the driving device 30 is arranged on the bracket 10 and connected to the photovoltaic panel 20, and the driving device 30 is used to drive the photovoltaic panel 20 to switch between a horizontal state and an inclined state. When the photovoltaic panel 20 is in the inclined state, the lower end edge of the photovoltaic panel 20 faces the inside of the water receiving groove 11.

[0034] In the sunshade awning 100 of the embodiment of the utility model, the driving device 30 enables the photovoltaic panel 20 to switch between a horizontal state and an inclined state. When the photovoltaic panel 20 is in the inclined state, the lower edge of the photovoltaic panel 20 faces the inside of the water receiving trough 11, which helps rainwater flow along the inclined surface of the photovoltaic panel 20 to the water receiving trough 11, thereby avoiding the accumulation of rainwater on the photovoltaic panel 20. Reducing the accumulation of water can maintain the effective receiving area of ​​the photovoltaic panel 20, thereby improving the photoelectric conversion efficiency.

[0035] In addition to preventing rainwater from accumulating, the tilted state also helps dust and debris on the photovoltaic panel 20 to be washed away with rainwater, reducing pollution on the surface of the photovoltaic panel 20 and further improving the photoelectric conversion efficiency. In addition, the photovoltaic panel 20 has different requirements for tilt angles in different seasons and weather conditions. Through the drive device 30, the angle of the photovoltaic panel 20 can be adjusted according to the actual sunshine conditions and weather changes to obtain the best lighting conditions and power generation efficiency.

[0036] Specifically, the awning 100 can be made of materials such as metal or plastic, and can resist external environmental factors such as wind, rain, snow, etc. The awning 100 can be applied to areas such as the periphery of outdoor public and large commercial facilities or the courtyard of a private residence.

[0037] The bracket 10 is a structure for supporting and fixing the photovoltaic panel 20, providing a mounting base for the photovoltaic panel 20, so that the photovoltaic panel 20 can operate stably. The bracket 10 can be made of metal or other high-strength materials, and the bracket 10 can be used to support the photovoltaic panel 20 and keep it in a fixed position. The number of brackets 10 can be multiple, and multiple brackets 10 can support the photovoltaic panel 20 at different supporting points, thereby improving the stability of the photovoltaic panel 20.

[0038] The photovoltaic panel 20 is used to convert solar energy into electrical energy. The electrical energy converted by the photovoltaic panel 20 can be used by the driving device 30. The photovoltaic panel 20 can be different types of solar energy conversion devices such as monocrystalline silicon, polycrystalline silicon or thin-film solar cells, and photovoltaic panels 20 of different efficiencies and sizes can be selected as needed. The photovoltaic panel 20 can be set on the top of the bracket 10 in a slot connection manner. For example, the edge of the photovoltaic panel 20 can be directly inserted into the corresponding slot on the bracket 10 and fixed by a spring clip, a pressure block or a hand tightening screw. Of course, according to actual needs, the photovoltaic panel 20 can also be set on the bracket 10 by other connection methods such as threaded connection and clamp connection.

[0039] The driving device 30 can be connected to the photovoltaic panel 20 by mechanical or electric means, and the driving device 30 can drive the photovoltaic panel 20 to switch between a horizontal state and an inclined state. The driving mode of the driving device 30 can be a motor 31 drive, a hydraulic drive, or a pneumatic drive.

[0040] The driving device 30 can be used to adjust the angle of the photovoltaic panel 20 to adapt to the change of the sun's position. The tilt angle of the photovoltaic panel 20 can be adjusted according to the change of the sunshine conditions. For example, when the sun rises, moves or sets, the driving device 30 can drive the photovoltaic panel 20 according to the preset program or the real-time monitoring data to make the photovoltaic panel 20 at different angles to maintain the best incident angle between the photovoltaic panel 20 and the sunlight. The real-time monitoring data can be realized by observation equipment such as a sun angle sensor.

[0041] On rainy days, the driving device 30 can drive the photovoltaic panel 20 to switch the photovoltaic panel 20 from a horizontal state to an inclined state, and cooperate with the water receiving trough 11 on the bracket 10 to collect the accumulated water on the photovoltaic panel 20.

[0042] The horizontal state refers to the state in which the photovoltaic panel 20 is parallel to the ground. On rainy days, rainwater easily accumulates on the photovoltaic panel 20, thereby affecting the photoelectric conversion efficiency of the photovoltaic panel 20. The inclined state refers to the state in which the photovoltaic panel 20 is not parallel to the ground. In this state, the lower edge of the photovoltaic panel 20 faces the inside of the water receiving trough 11, which is convenient for draining the photovoltaic panel 20. Among them, the lower edge of the photovoltaic panel 20 refers to the edge of the photovoltaic panel 20 that is at a lower position when in an inclined state.

[0043] The water receiving trough 11 is a trough formed on the bracket 10, and the water receiving trough 11 is used to collect rainwater flowing down from the photovoltaic panel 20. The shape of the water receiving trough 11 can be a regular shape such as a long strip, a trapezoid or a multi-stage shape, or it can be an irregular shape, and the depth and width of the water receiving trough 11 can be set according to demand. The lower edge of the photovoltaic panel 20 can be higher than the opening of the water receiving trough 11, or it can be lower than the opening of the water receiving trough 11, or the lower edge of the photovoltaic panel 20 can extend into the water receiving trough 11. When the driving device 30 drives the photovoltaic panel 20 to switch from a horizontal state to an inclined state, the rainwater accumulated on the photovoltaic panel 20 can flow to the inside of the water receiving trough 11 under the action of gravity, thereby completing the drainage of the photovoltaic panel 20 and the collection of rainwater.

[0044] See also Figure 2 In some embodiments, when the photovoltaic panel 20 is in a tilted state, the lower edge of the photovoltaic panel 20 is located in the water receiving groove 11.

[0045] In this way, when the lower edge of the photovoltaic panel 20 is located in the water receiving groove 11, rainwater can be prevented from directly impacting the ground or other objects, thereby reducing water splashing and water erosion, and reducing the probability that the area below the photovoltaic panel 20 is adversely affected by rainwater.

[0046] Specifically, when the photovoltaic panel 20 is tilted, the lower edge of the photovoltaic panel 20 is located in the water receiving trough 11, so that rainwater can flow directly from the photovoltaic panel 20 into the water receiving trough 11, thereby avoiding water leakage during the process of rainwater flowing from the photovoltaic panel 20 into the water receiving trough 11.

[0047] See also Figure 1 and Figure 3 In some embodiments, the photovoltaic panel 20 includes a plurality of sub-panels 21, and the plurality of sub-panels 21 are arranged to form at least one column. The water receiving trough 11 extends along the column direction L of the plurality of sub-panels 21. When each column of sub-panels 21 is in an inclined state, the lower end edge of each column of sub-panels 21 faces the inside of the water receiving trough 11.

[0048] In this way, the design of the sub-panel 21 allows for independent maintenance or replacement of a single or several sub-panels 21 without disassembling the entire photovoltaic panel 20, which greatly simplifies maintenance work and reduces maintenance costs. At the same time, by allowing the water receiving trough 11 to extend along the column direction L of the sub-panels 21 of the photovoltaic panel 20, the driving device 30 can simultaneously drive a column of sub-panels 21, so that the sub-panels 21 in the column can all face the inside of the water receiving trough 11 at the same time, which can not only reduce the use cost of the driving device 30, but also more efficiently collect the accumulated water on each column of sub-panels 21, thereby improving the water collection efficiency of the entire awning 100.

[0049] Specifically, the sub-panel 21 is a single module constituting the photovoltaic panel 20, and a plurality of sub-panels 21 can be arranged according to certain rules, for example, they can be arranged in a straight line. The sub-panels 21 can be tilted or adjusted independently, so the sub-panels 21 can be in a tilted state simultaneously or in a time-sharing manner. When the driving device 30 drives a column of sub-panels 21 to tilt at the same time, each sub-panel 21 in a column can face the inside of the water receiving tank 11. Sub-panels 21 in different columns can be arranged at intervals to reduce the probability of interference with sub-panels 21 in adjacent columns when the state of the sub-panels 21 is switched.

[0050] See also Figure 2 In some embodiments, a plurality of sub-boards 21 are arranged to form two columns, and the inclination directions of the sub-boards 21 in the two columns are opposite.

[0051] Thus, by making the inclination directions of the two rows of sub-boards 21 opposite to each other, a symmetrical drainage design is formed, which can balance the force distribution of the photovoltaic panel 20 during drainage and reduce the asymmetric pressure on the structure of the bracket 10. At the same time, one water receiving trough 11 can provide drainage function for the two rows of sub-boards 21 at the same time, which makes the structure of the awning 100 compact and reduces the number of water receiving troughs 11, thereby reducing the manufacturing cost of the awning 100.

[0052] See also Figure 2 and Figure 4In some embodiments, each column of sub-boards 21 is mounted on the same rotating shaft 40 , and the rotating shaft 40 is connected to a driving device 30 , and the driving device 30 drives each column of sub-boards 21 to rotate as a whole through the rotating shaft 40 .

[0053] Thus, by installing each column of sub-boards 21 on the same rotating shaft 40 and controlling them through one driving device 30, centralized control of multiple columns of sub-boards 21 is achieved, simplifying the operation process. At the same time, this centralized control method can also reduce the number of driving devices 30, thereby reducing the maintenance and use costs of the driving devices 30.

[0054] Specifically, the driving device 30 may correspond to the rotating shaft 40 one by one, or one driving device 30 may correspond to multiple rotating shafts 40. The driving device 30 may drive the rotating shaft 40 to rotate through the motor 31, thereby driving each column of sub-boards 21 to rotate as a whole. The driving device 30 may include a motor 31 and a gear assembly 32. The motor 31 may be arranged on the bracket 10 and electrically connected to the photovoltaic panel 20. The gear assembly 32 connects the rotating shaft 40 and the motor 31. The motor 31 may be a DC motor, an AC motor, a servo motor or a stepper motor, etc. The specific type may be selected according to actual needs. The motor 31 may be mounted on the bracket 10 by a mechanical fixing method, such as bolt fixing, welding or clamping.

[0055] The photovoltaic panel 20 can be used to provide electric energy to the motor 31. The electrical connection between the motor 31 and the photovoltaic panel 20 can be achieved by means of wires or cables, and the cables are connected from the input end of the motor 31 to the output end of the photovoltaic panel 20. Between the motor 31 and the photovoltaic panel 20, a battery or a transformer circuit can be provided.

[0056] The gear assembly 32 can be connected to the motor 31 and the rotating shaft 40 by key connection, spline connection or direct meshing. The gear assembly 32 is used to convert the rotation speed and torque of the motor 31 into parameters suitable for the rotating shaft 40. The gear assembly 32 may include a plurality of gears, the plurality of gears are meshed with each other, and the speed ratio of the plurality of gears is greater than 1. The gear transmission is more stable than the direct transmission of the motor 31, so the photovoltaic panel 20 can rotate stably. At the same time, since the speed ratio of the plurality of gears is greater than 1, the gear assembly 32 can reduce the speed output by the motor 31, so that the photovoltaic panel 20 can be adjusted in smaller angle increments, which is easy to control.

[0057] The number of the rotating shafts 40 may correspond to the number of the sub-plates 21 one by one, and the rotating shafts 40 may be fixedly connected to the sub-plates 21 by welding, bolting, etc., so that each column of sub-plates 21 can rotate along with the rotating shafts 40. Since each column of sub-plates 21 is mounted on the same rotating shaft 40, the sub-plates 21 in one column share an axis, and the sub-plates 21 in one column can rotate around the axis at the same time.

[0058] See also Figure 1 and Figure 2 In some embodiments, the bracket 10 includes a support column 12 and a frame 13 disposed at one end of the support column 12 , the photovoltaic panel 20 is mounted on the frame 13 , and the frame 13 is formed with a water receiving trough 11 .

[0059] In this way, by installing the photovoltaic panel 20 on the frame 13 at one end of the support column 12, a stable structure is formed, thereby providing stable support for the photovoltaic panel 20. The water receiving trough 11 is integrated on the frame 13, which can reduce the use cost caused by adding additional components and improve the space utilization of the awning 100.

[0060] Specifically, the support column 12 is a part of the bracket 10, which plays the role of bearing and transferring loads, and can be made of high-strength materials, such as metals, alloys, etc., to ensure the stability of the entire structure. The frame 13 is a structure at one end of the support column 12, which is used to fix and support the photovoltaic panel 20. The frame 13 may include cross beams, longitudinal beams or other supporting components of other shapes to accommodate photovoltaic panels 20 of different sizes. Different parts of the frame 13 may have different functions. For example, the frame 13 may include cross beams and longitudinal beams staggered with the cross beams, the cross beams can be used to support the photovoltaic panel 20, and the longitudinal beams can be used to form a water receiving trough 11.

[0061] The photovoltaic panel 20 can be arranged on the frame 13 by means of slot connection, bolt connection, adhesion, etc., or can be fixed to the frame 13 by means of a clamp or other components. The water receiving trough 11 can be arranged close to the photovoltaic panel 20 to collect rainwater flowing out of the photovoltaic panel 20.

[0062] See also Figure 2 and Figure 3 In some embodiments, the frame 13 is formed with a drain port 130 that is connected to the water receiving tank 11.

[0063] In this way, the drain port 130 formed on the frame 13 is connected to the water receiving trough 11, which can ensure that rainwater flows smoothly from the water receiving trough 11 to the drain port 130, so as to be quickly discharged from the awning 100, reducing the adverse effects caused by water accumulation in the water receiving trough 11. For example, since rainwater can be quickly discharged through the drain port 130, maintenance and cleaning work caused by water accumulation is reduced, thereby reducing maintenance costs.

[0064] Specifically, the drain port 130 can be a simple opening or a structure with an adjusting valve to control the drainage rate. The shape of the drain port 130 can be a regular shape such as a circle or a square, or an irregular shape. The number of the drain ports 130 can be one or more, and the multiple drain ports 130 can be arranged at intervals to ensure that all the water in the water receiving trough 11 can be discharged. A guide plate or a guide ridge can be provided in the water receiving trough 11 to guide the direction of the water flow and prevent the water flow from forming a dead water area in the water receiving trough 11.

[0065] In some embodiments, the drain port 130 is located at the lowest point of the water receiving tank 11 .

[0066] In this way, since the drain port 130 is located at the lowest point of the water receiving trough 11 , under the action of gravity, the accumulated water in the water receiving trough 11 will gather toward the drain port 130 , thereby ensuring that the rainwater can be discharged smoothly.

[0067] Specifically, the lowest point of the water receiving trough 11 refers to the lowest part of the water receiving trough 11 in the structure, which is the place where the accumulated water finally stays under the action of gravity. The bottom wall of the water receiving trough 11 can have an appropriate slope so that water can flow smoothly to the drain port 130. The bottom wall of the water receiving trough 11 should be smooth to reduce the friction resistance of the water flow and make the water flow smoother.

[0068] See also Figure 1 In some embodiments, the awning 100 further includes a camera device 50 disposed on the bracket 10 , and the camera device 50 is used to capture an image of the upper surface of the photovoltaic panel 20 .

[0069] In this way, the camera device 50 can confirm the water accumulation on the photovoltaic panel 20 by taking images of the upper surface of the photovoltaic panel 20 in real time or periodically to evaluate the cleaning needs, so that the driving device 30 can cooperate with the water receiving trough 11 to promptly remove the accumulated water on the photovoltaic panel 20.

[0070] Specifically, the camera device 50 can be a fixed camera or a movable camera, which is used to capture the image of the upper surface of the photovoltaic panel 20. The camera device 50 can be set on the bracket 10 by bolt connection, magnetic attraction, etc. The shooting angle of the camera device 50 can be adjusted to ensure that the field of view of the camera device 50 can fully cover the upper surface of the photovoltaic panel 20. The number of camera devices 50 can be one or more, and multiple camera devices 50 can be arranged on the bracket 10 at intervals, and multiple camera devices 50 can obtain a wider field of view. The electric energy required by the camera device 50 can also be provided by the photovoltaic panel 20. The camera device 50 and the photovoltaic panel 20 can be directly connected by a cable, or they can be electrically connected through intermediate equipment such as a junction box or a busbar.

[0071] According to the image of the upper surface of the photovoltaic panel 20 captured by the camera device 50, the driving device 30 can automatically drive the photovoltaic panel 20 to complete the drainage of the photovoltaic panel 20. When it is confirmed that there is water accumulation on the upper surface of the photovoltaic panel 20, the camera device 50 can communicate with the driving device 30 or other equipment that controls the driving device 30, so that the driving device 30 drives the photovoltaic panel 20, so that the photovoltaic panel 20 is in a tilted state, so that the accumulated water on the photovoltaic panel 20 flows into the inside of the water receiving tank 11.

[0072] See also Figure 1 and Figure 5 In some embodiments, the awning 100 also includes a base 60 and a storage battery 70 , the bracket 10 is connected to the base 60 , the storage battery 70 is electrically connected to the photovoltaic panel 20 , and the storage battery 70 is disposed in the base 60 .

[0073] In this way, the base 60 provides a more stable foundation for the entire awning 100, making the bracket 10 and the photovoltaic panel 20 arranged on the bracket 10 more stable, thereby enhancing the stability of the overall structure of the awning 100.

[0074] The design of the integrated energy storage battery 70 simplifies the installation process, because there is no need to separately place the energy storage battery 70 outside the awning 100, thereby reducing the number of installation points and wiring, making maintenance more convenient, and avoiding external messy lines and equipment, improving the overall aesthetics of the awning 100. In addition, the design of the built-in energy storage battery 70 reduces the impact of external factors on the energy storage battery 70, such as weather changes or accidental impacts, thereby improving the safety of the entire energy storage battery 70.

[0075] Specifically, the base 60 is the supporting foundation of the photovoltaic awning 100, and the base 60 can be made of a strong and durable material, such as wood, metal or high-strength plastic. The base 60 can be used for people to walk around or place items. The base 60 can be fixed to the bottom of the bracket 10 by bolts, screws or welding, or fixed to the base 60 by plug-in connection. For example, the bottom of the bracket 10 is designed with a slot or a tubular structure for inserting the base 60, which is locked by a pin or a buckle.

[0076] The base 60 may be provided with a mounting hole, which may be used to connect to the bottom of the bracket 10. A gasket or a sealing ring may be provided at the connection between the bracket 10 and the base 60 to improve stability and weatherproof performance.

[0077] The energy storage battery 70 can be a lithium-ion battery, a lead-acid battery, or other types of rechargeable batteries. The energy storage battery 70 is used to store the electrical energy generated by the photovoltaic panel 20, and can power loads such as household appliances and portable devices. The energy storage battery 70 and the photovoltaic panel 20 can be directly connected by a cable, or they can be electrically connected through an intermediate device such as a junction box or a busbar. The energy storage battery 70 can be connected to the inner surface of the base 60 by gluing, threading, etc. Among them, the gluing method can prevent shock and reduce mechanical wear. The base 60 can be provided with a battery tray or a fixing frame to facilitate the installation or removal of the energy storage battery 70.
