Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic energy storage devices, and specifically to an outdoor photovoltaic energy storage device with an adjustable bracket structure. Background Art

[0002] A photovoltaic energy storage device is a device that converts solar energy into electrical energy and stores it. The photovoltaic energy storage device mainly consists of a photovoltaic module and an energy storage system. In order to enable the photovoltaic module to receive sunlight more efficiently, brackets with adjustable tilt angles are currently commonly used to install the photovoltaic module.

[0003] Currently, common photovoltaic modules are mainly placed outdoors by brackets. In the case of snow in winter, snow is extremely likely to adhere to the surface of the photovoltaic panel, which has many adverse effects on the normal operation of the photovoltaic module, such as reducing the photoelectric conversion efficiency and increasing the component load. At present, the methods for dealing with the problem of snow accumulation on the photovoltaic panel have obvious drawbacks. One way is to arrange for workers to carry special tools to the site for snow removal after the snowfall. This process not only consumes a large amount of manpower and is extremely cumbersome to operate, but also is greatly restricted by the geographical environment and the installation location of the photovoltaic module. For example, in some areas with complex terrain or high installation height of the module, manual snow removal is difficult and there are certain safety risks; another common practice is to install a heating structure on the photovoltaic component. When snow accumulation occurs, the structure uses pre-stored electrical energy to generate heat, thereby melting the snow to achieve the purpose of snow removal. However, it is found through retrieval that in the patent with the application number 202310809152.5, a solar photovoltaic power generation system and method are disclosed. In this photovoltaic power generation system, a heating strip cluster is arranged on the lower surface of the photovoltaic module. The heating strip cluster includes several heating strips, and each heating strip is used to heat a unit area of the photovoltaic module, and can melt the snow covering the photovoltaic module. However, this method has serious problems of electric energy waste. On the one hand, the energy consumption of the heating structure is large, and a large amount of electric energy that could originally be used for power generation needs to be consumed; on the other hand, in the case of heavy snowfall or continuous snowfall, the heating device may need to be turned on for a long time, further exacerbating the consumption of electric energy. This undoubtedly increases the cost of photovoltaic power generation and reduces the overall efficiency. For this reason, we propose an outdoor photovoltaic energy storage device with an adjustable bracket structure. Summary of the Invention

[0004] To solve the above technical problems, an embodiment of the present application provides an outdoor photovoltaic energy storage device with an adjustable bracket structure, including an adjustable bracket and a photovoltaic component installed on the upper end surface of the adjustable bracket, and further including: A water supply component for spraying water onto the upper end of the inclined photovoltaic component; An active pressure-bearing component and a pressure adjustment component. The active pressure-bearing component is installed at the end of an adjustable bracket through an extension plate and is located on one side of the water outlet end of the water supply component. The pressure adjustment component includes a force application member and an adjustment member connected to each other. One end of the force application member away from the adjustment member is hinged to the active pressure-bearing component, and the adjustment member is connected to the pipeline of the water supply component. When the active pressure-bearing component is deflected or moved downward under pressure, the force application member acts on the adjustment member to open the pipeline of the water supply component. A centrifugal limiting component is vertically arranged in the middle of the active pressure-bearing component. In strong winds, the deflection of the active pressure-bearing component is limited by the centrifugal limiting component.

[0005] In some embodiments, the water supply component includes a booster water tank fixed to the lower end of the adjustable bracket. A water supply pipe is connected to the bottom end of the side wall of the booster water tank. The water outlet end of the water supply pipe is connected to a water outlet pipe at the end of the photovoltaic component. A plurality of water outlet nozzles are equidistantly installed on one side of the water outlet pipe close to the photovoltaic component.

[0006] In some embodiments, the active pressure-bearing component includes two vertically parallel and fixed vertical plates. On the opposite sides of the two vertical plates, there are symmetrically arranged liftable mounting plates. One inclined plate is hinged to each of the two mounting plates. The two inclined plates are inclined relative to each other, and a first spring is connected between the lower end surface of the inclined plate and the extension plate.

[0007] In some embodiments, on the opposite sides of the two vertical plates, there are chutes with a large inner and a small outer diameter. A sliding strip is connected to the mounting plate and is adapted to the chute.

[0008] In some embodiments, the adjustment member includes a hinge bar and an adjustment rod. Two connecting bars are fixed to the outside of the adjustment rod. The hinge bar is hinged between the lower end surface of the inclined plate and the corresponding connecting bar.

[0009] In some embodiments, the force application member includes a connection box arranged outside the water supply pipe. A baffle is arranged inside the water supply pipe and within the area covered by the connection box. The end of the adjustment rod is connected to the side wall of the baffle, and the adjustment rod penetrates through the water supply pipe and the connection box.

[0010] In some embodiments, the centrifugal limiting component includes an inverted concave-shaped frame, a hollow connecting column, and a wind speed cup. The hollow connecting column vertically penetrates through the inverted concave-shaped frame in a liftable manner. The wind speed cup is rotatably installed at the top of the hollow connecting column through a bearing. A connecting rod with its top fixed to the wind speed cup is arranged inside the hollow connecting column. An active limiting member is installed at the bottom end of the connecting rod.

[0011] In some embodiments, the movable limiting member includes a cylindrical frame fixed to the lower end of the outer part of the connecting rod. A convex ring is fixed in the middle of the interior of the cylindrical frame. A plurality of second springs are connected in a circumferential array on the outer circumference of the convex ring. The ends of the second springs are connected to limiting rods passing through the cylindrical frame. A retaining ring is fixed to the outer part of the limiting rod near one end of the second spring. A limiting strip is fixed to the lower end surface of the inclined plate near the end. A groove for receiving the outer end of the limiting rod is formed in the limiting strip.

[0012] In some embodiments, a connecting ring is fixed to the outer part of the hollow connecting column, and a third spring is connected between the connecting ring and the inverted concave frame.

[0013] In some embodiments, a convex block is connected to the outer part of the adjusting rod and inside the connecting box, and a stop block for blocking after the convex block deflects 90° is connected to the inner wall of the connecting box.

[0014] The present invention has at least the following beneficial effects: 1. Saving energy and resources: By setting up the movable pressure-bearing assembly and other components, the physical structure linkage-triggered water supply and snow removal method does not require additional energy to detect the snow volume, which saves energy consumption. Moreover, water is supplied for snow removal only when the accumulated snow reaches a certain level and triggers the action of the inclined plate, avoiding the waste of water resources and realizing energy-saving snow removal operation.

[0015] 2. Compact structure and high reliability: The water supply assembly is controlled by using the deflection, downward movement of the inclined plate and the linkage of the adjusting member. The structure of the whole device is relatively compact, and each component is closely matched through mechanical linkage. There is no need for complex electronic sensors to detect the snow volume, reducing the risk of failure of electronic devices in the harsh snowy weather environment and improving the reliability of the system.

[0016] 3. Reducing maintenance costs: The traditional snow removal method for photovoltaic modules usually requires manual cleaning or using stored electric energy, while this automatic snow removal method is triggered by the snow pressure and does not require a large amount of additional manpower and electric energy to drive, reducing the maintenance cost and manpower cost of the photovoltaic system.

[0017] 4. Enhancing wind resistance and ensuring stable operation: The centrifugal limiting assembly is configured. When encountering strong wind weather, the wind speed cup rotates to drive the limiting rod to move outwards, stretching the second spring. The end of the extended limiting rod can be stuck into the groove of the limiting strip. This fitting state can effectively limit the damage caused by excessive deflection when the strong wind blows the inclined plate, providing a solid guarantee for stable operation.

Detailed implementation manners

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] Embodiment 1: Please refer to Figures 1-12 As shown, the present invention provides a technical solution: an outdoor photovoltaic energy storage device with an adjustable bracket structure, including an adjustable bracket 1 and a photovoltaic component 2 installed on the upper end surface of the adjustable bracket 1. The adjustable bracket 1 is a bracket with adjustable inclination, which is prior art. The specific structure and the inclination adjustment process will not be elaborated here. It also includes a water supply component 3, a movable pressure-bearing component 4, a centrifugal limiting component 5, and a pressure adjustment component 6. The water supply component 3 is used to spray water on the upper end of the inclined photovoltaic component 2, so as to facilitate the snow falling on the photovoltaic component 2 to slide down when it snows in winter (the water will form a thin liquid film between the snow and the photovoltaic panel, and the water, as a lubricant, will significantly reduce the friction between the snow and the photovoltaic panel). The movable pressure-bearing component 4 is installed at the end of the adjustable bracket 1 through an extension plate and is located on one side of the water outlet end of the water supply component 3. The pressure adjustment component 6 includes a force-applying member 61 and an adjustment member 62 connected to each other. One end of the force-applying member 61 away from the adjustment member 62 is hinged to the movable pressure-bearing component 4, and the adjustment member 62 is connected to the pipeline of the water supply component 3. When the movable pressure-bearing component 4 is deflected or moved downward under pressure, the force-applying member 61 acts on the adjustment member 62 to open the pipeline of the water supply component 3. The centrifugal limiting component 5 is vertically arranged in the middle of the movable pressure-bearing component 4. When there is strong wind, the deflection of the movable pressure-bearing component 4 is limited through the centrifugal limiting component 5 to limit the movement of the movable pressure-bearing component 4 and reduce the occurrence of its damage.

[0022] Among them, please refer to Figures 1-4 As shown, the water supply component 3 includes a pressurized water tank 31 fixed to the lower end of the adjustable bracket 1. A water supply pipe 32 is connected to the bottom end of the side wall of the pressurized water tank 31. The water outlet end of the water supply pipe 32 is connected to a water outlet pipe 33 at the end of the photovoltaic component 2. A plurality of water outlet nozzles 34 are equidistantly installed on the side of the water outlet pipe 33 close to the photovoltaic component 2. The pressurized water tank 31 is a pressurized water tank, so that after the pipeline is connected, water can be sent into the water outlet pipe 33. A water replenishing pipe is provided on the upper end surface of the pressurized water tank 31, and a valve is installed on the water replenishing pipe. Moreover, heat preservation layers are provided on the exteriors of the pressurized water tank 31, the water supply pipe 32, and the water outlet pipe 33 to prevent the water inside from freezing in severe winter. After the pipeline is connected, the water in the pressurized water tank 31 is sent into the water outlet pipe 33 under pressure through the water supply pipe 32, and then sent to the photovoltaic component 2 through the water outlet nozzles 34. And when the staff conducts regular inspections, the pressurization and water replenishment of the pressurized water tank 31 can be carried out to maintain the required state.

[0023] Please refer to Figures 5-7As shown in the figure, the movable pressure-bearing assembly 4 includes two vertically parallel and fixed vertical plates 43. On the opposite sides of the two vertical plates 43, there are symmetrically arranged liftable mounting plates 42. On each of the two mounting plates 42, there is a hinged inclined plate 41. The two inclined plates 41 are inclined relative to each other, and a first spring 45 is connected between the lower end surface of the inclined plate 41 and the extension plate. On the opposite sides of the two vertical plates 43, there are chutes 46 with a larger inner size and a smaller outer size. The mounting plate 42 is connected with a slide bar 44 that cooperates with the chute 46. When it snows, the snow falls on the inclined plate 41, and the inclined plate 41 deflects downward along the hinge axis. When the two inclined plates 41 deflect, a linkage effect will be generated, driving the adjusting member 62 to move downward along a specific track. The downward movement of the adjusting member 62 can adjust the force-applying member 61. Among them, when the snow volume is large, there is more snow accumulated on the inclined plate 41. Through the movement of the slide bar 44 along the chute 46, the weight of the snow can press the inclined plate 41 downward. At this time, the water supply assembly 3 can also be triggered to discharge water.

[0024] Refer to Figures 10-11 As shown in the figure, the adjusting member 62 includes a hinged bar 621 and an adjusting rod 623. Two connecting bars 622 are fixed to the outside of the adjusting rod 623. The hinged bar 621 is hinged between the lower end surface of the inclined plate 41 and the corresponding connecting bar 622. When the inclined plate 41 deflects downward or moves downward, at this time, the first spring 45 is compressed, driving the hinged bar 621 to move downward to push the connecting bar 622 downward.

[0025] Refer to Figures 10-11 As shown in the figure, the force-applying member 61 includes a connection box 611 provided outside the water supply pipe 32. Inside the water supply pipe 32 and within the area covered by the connection box 611, there is a baffle 612. The end of the adjusting rod 623 is connected to the side wall of the baffle 612, and the adjusting rod 623 penetrates through the water supply pipe 32 and the connection box 611. When the hinged bar 621 pushes the connecting bar 622 downward, the displacement of the connecting bar 622 will drive the connected adjusting rod 623 to rotate. During the rotation of the adjusting rod 623, the baffle 612 that originally tightly blocked the water supply pipe 32 will flip. As the baffle 612 continuously flips, the blocking state between it and the water supply pipe 32 is broken, and the water supply pipe 32 is opened. The water that was originally blocked in the pipe can then smoothly pass through the water supply pipe 32 and be sent out, thus realizing the water delivery function.

[0026] Refer to Figures 8-9 and Figure 12As shown, the centrifugal limiting component 5 includes a concave frame 51, a hollow connecting column 53 and an anemometer cup 52. The hollow connecting column 53 vertically penetrates through the concave frame 51 in a liftable manner. The concave frame 51 is installed on the extension plate. A connecting ring is fixed to the outside of the hollow connecting column 53. A third spring 55 is connected between the connecting ring and the concave frame 51. The anemometer cup 52 is rotatably installed at the top of the hollow connecting column 53 through a bearing. A connecting rod 56 with its top fixed to the anemometer cup 52 is provided inside the hollow connecting column 53. A movable limiting member 54 is installed at the bottom end of the connecting rod 56.

[0027] Among them, the movable limiting member 54 includes a cylindrical frame 541 fixed to the lower end of the outside of the connecting rod 56. A convex ring 544 is fixed at the middle of the inside of the cylindrical frame 541. A plurality of second springs 543 are connected in a circular array on the outer circumference of the convex ring 544. The end of the second spring 543 is connected to a limiting rod 542 penetrating through the cylindrical frame 541. A retaining ring 545 is fixed to the outside of the limiting rod 542 and near one end of the second spring 543. A limiting strip 7 is fixed to the lower end surface of the inclined plate 41 near the end. A groove for accommodating the outer end of the limiting rod 542 is formed on the limiting strip 7.

[0028] Through the above, when encountering strong wind weather, the anemometer cup 52 will rotate rapidly under the drive of the wind force. During this rotation process, due to the generation of centrifugal force, the limiting rod 542 is driven to gradually move outward. At this time, the second spring 543 connected to the limiting rod 542 is also stretched accordingly and is in a stretched state under force. During the continuous rotation of the plurality of limiting rods 542, at least one limiting rod 542 in the extended state has its end exactly located in the groove of the limiting strip 7. This ingenious fitting state is like installing a stable safety device on the inclined plate 41, effectively restricting the damage caused by excessive deflection that may occur when the strong wind blows the inclined plate 41, thereby providing a solid guarantee for the stable operation of the equipment.

[0029] In the case of general wind force, the wind force at this time can drive the anemometer cup 52 to rotate, but the centrifugal force is not enough to drive the limiting rod 542 to extend too much, so that the separation can blow the inclined plate 41 to deflect at this time to realize the water outlet of the water delivery component 3, and the dust removal and ash cleaning of the photovoltaic component 2 can be realized in non-snow weather.

[0030] In the harsh environment of a blizzard, the wind speed cup 52 will rotate at high speed due to the continuous action of strong winds. The force generated by this high-speed rotation can effectively lock the deflection of the inclined plate 41, ensuring that the inclined plate 41 remains stable under a specific state. However, since the inclined plate 41 is exposed to wind and snow for a long time, snow will gradually accumulate on its surface. As the amount of snow continues to increase, the weight of the snow generates a downward pulling force, which in turn drives the inclined plate 41 to start moving downward synchronously, and the wind speed cup 52 will also move downward with the inclined plate 41 in this process. When the inclined plate 41 moves down to a specific position, it will trigger the relevant linkage mechanism of the water delivery component 3, causing the water delivery component 3 to start discharging water, thereby effectively carrying out the snow removal operation.

[0031] Example 2: Please refer to Figure 11 As shown, this embodiment is an extension of embodiment 1: a protrusion 613 is connected to the outside of the adjustment rod 623 and located inside the connection box 611, and a stopper 614 is connected to the inner wall of the connection box 611 for blocking the protrusion 613 when it deflects 90°.

[0032] As described above, when the adjustment rod 623 rotates, the baffle 612 connected thereto will be driven to rotate synchronously. At the same time, the protrusion 613 fixed on the adjustment rod 623 will also move with the rotation of the adjustment rod 623. As the adjustment rod 623 continues to rotate, the baffle 612 also continuously changes its angle. When the baffle 612 rotates to 90°, the protrusion 613, which was originally on the motion trajectory, just moves to the position of contact with the stopper 614. At this time, since the position of the stopper 614 is fixed and the protrusion 613 continues to move and resists the stopper 614, the stopper 614 can effectively block the protrusion 613, thereby limiting the further rotation of the adjustment rod 623, so that the deflection angle of the device reaches the maximum and prevents further rotation.

[0033] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0034] While the embodiments of the present invention have been shown and described, it will be apparent to those skilled in the art that various changes, modifications, substitutions, and alterations can be made to the embodiments without departing from the principles and spirit of the invention.
