Description

Technical Field

[0001] This invention relates to the field of energy storage cabinet technology, and more particularly to a photovoltaic energy storage module for an energy storage battery compartment. Background Technology

[0002] Photovoltaic power generation, as a renewable energy source, is currently used in most modular energy storage cabinets. The power generation system converts sunlight into electrical energy and stores it in the photovoltaic energy storage module. Then, the power inverter converts the electrical energy into alternating current to supply power to users.

[0003] Existing photovoltaic energy storage modules dissipate heat through a cooling system. By installing a filter at the air inlet, dust is prevented from entering and covering the energy storage module to ensure its energy storage capacity and efficiency. Since the energy storage module is often placed outdoors, when used in high-temperature environments, the module may overheat or experience insufficient heat dissipation due to factors such as sunlight or heat dissipation efficiency, affecting its safety and performance. At the same time, when used in low-temperature environments, the insulation effect of the energy storage module may cause it to cool down, reducing its energy storage capacity and severely impacting the user experience. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that the safety and performance of energy storage modules in high or low temperature environments are seriously affected by environmental factors, and to propose a photovoltaic energy storage module for an energy storage battery compartment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A photovoltaic energy storage module for an energy storage battery compartment includes a power generation component, an energy storage component, and a suspension component, wherein the power generation component includes a photovoltaic power generation panel; The energy storage component includes a storage box and a battery module. The battery module is located inside the storage box, and a settling belt is fixed to one end of the storage box. The suspension assembly includes a suspension bracket, a telescopic arm, a drive assembly, a fixing assembly, a reaction force assembly, an external connection assembly, and a top fastening assembly. The outer side of the suspension bracket has a mating flip-over groove, and the inner wall of the mating flip-over groove has a following slider. One end of the following slider is hinged to a bottom push rod, and one end of the bottom push rod is fixed to a limit push rod. A flip-over tongue is fitted in the middle of the limit push rod, and one end of the flip-over tongue is fixed to a flip-over support rod. One end of the flip-over support rod is tightly fitted to the surface of the storage box, and one end of the flip-over tongue is fitted with a lifting rod. Both ends of the lifting rod are connected to the suspension bracket via built-in grooves. The inner wall of the telescopic arm is connected to a following rod via a tension spring, and the top end of the following rod is connected to a pressing plate via a reset assembly. The end of the pressing plate near the storage box has a slope.

[0006] Preferably, the closed ends of the two photovoltaic panels are connected by a hinge, allowing them to be laid flat and folded according to the usage environment.

[0007] Preferably, the drive assembly includes a stepper motor, the middle part of which is connected to the lifting rod via a threaded groove.

[0008] Preferably, the fixing component includes an expansion bolt inserted into the inner wall of the inner convex plate of the suspension bracket.

[0009] Preferably, the top fastening assembly includes an inner lifting handle fixed to the top of the lifting rod and a top traction rod hinged to the inner side of the suspension bracket via a shaft. A supporting horizontal shaft is inserted into the inner wall of the top traction rod, and both ends of the supporting horizontal shaft pass through the storage box.

[0010] Preferably, the reaction force assembly includes a transmission belt sleeved on one end of the supporting horizontal shaft, a tensioning pulley inserted at one end of the transmission belt, the inner wall of the tensioning pulley being hinged to the surface of the storage box via a shaft, a flipping wheel engaged at one end of the tensioning pulley, the inner wall of the flipping wheel being hinged to the surface of the storage box via a shaft, and the outer side of the flipping wheel being fixedly connected to the telescopic arm.

[0011] Preferably, the external component includes a mounting base fixed to the surface of the photovoltaic panel, and a hinge arm is sleeved on the outside of the shaft of the mounting base, one end of the hinge arm being fixed to the surface of the extrusion plate.

[0012] Preferably, the reset assembly includes a T-bolt inserted into the inner wall of the follower rod, one end of the T-bolt being fixed to the surface of the extrusion plate, and a follower spring being fixed between the T-bolt and the surface of the follower rod.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention utilizes the coordinated arrangement of a flipping support rod and a telescopic arm. A stepper drive motor drives the lifting rod downwards, which, through a connected flipping tongue, drives the flipping support rod to push the bottom of the storage box outwards. Under the action of the following push rod and the connected bottom push rod, the flipping support rod can perform a flipping action, thereby changing the storage box from a vertical to an inclined position. During the flipping process, the part of the storage box connected to the top traction rod can also flip, while the top traction rod can drive the support horizontal axis to rotate. Under the drive of the counter-force component, the flipping wheel can rotate in the opposite direction, causing the photovoltaic panels to rotate from the top of the storage box to the side. Simultaneously, the extrusion plate moves along the ribs of the storage box. When sliding, the photovoltaic panels can be changed from a flat to a folded state, thus turning them into a sunshade covering the top of the storage box. This prevents the storage box from overheating due to direct sunlight. Furthermore, because the photovoltaic panels are folded and placed at a certain angle, the heat conducted from the photovoltaic panels can be dissipated. Folding the photovoltaic panels also reduces the area exposed to sunlight, preventing overcharging and reducing the energy storage burden on the energy storage module. In low-temperature environments, since the external temperature is much lower than the equipment temperature, the heat conducted from the photovoltaic panels to the back of the storage box and the heat dissipated from the storage box can converge here, achieving a heat preservation effect.

[0014] 2. By setting up a settling belt, the present invention can block dust in the air, preventing excessive dust from entering the surface of the photovoltaic power generation panel and the storage box and affecting the heat dissipation of the storage box. At the same time, in cold weather, it can block some air from entering, so that the heat is retained for a longer time, preventing the storage box from being too cold and affecting the energy storage capacity of the energy storage module.

[0019] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0020] Example, refer to Figures 1 to 8 A photovoltaic energy storage module for an energy storage battery compartment includes a power generation component, an energy storage component, and a suspension component. The power generation component includes a photovoltaic power generation panel 1. The closed ends of two photovoltaic power generation panels 1 are connected by a hinge, allowing them to be laid flat and folded according to the usage environment. It is worth noting that: when the photovoltaic panel 1 is placed on top of the storage box 2 in an unfolded state under normal temperature conditions, it can fully receive sunlight to generate electricity. However, when used in high temperature or low temperature environments, the photovoltaic panel 1 is folded and placed at an angle on top of the storage box 2 to achieve the effects of shading at high temperatures and heat preservation at low temperatures.

[0021] The energy storage component includes a storage box 2 and a battery module. The battery module is located inside the storage box 2, and a settling belt 3 is fixed to one end of the storage box 2. It is worth noting that the settling zone 3 can block dust in the air, preventing excessive dust from entering the surface of the photovoltaic panel 1 and the storage box 2 and affecting the heat dissipation of the storage box 2. At the same time, it can block some air from entering when the weather is cold, so that the heat is retained for a longer time, preventing the storage box 2 from being too cold and affecting the energy storage capacity of the energy storage module.

[0022] The suspension assembly includes a suspension bracket 4, a telescopic arm 13, and a drive assembly. Further, the drive assembly includes a stepper drive motor 17, the middle of which is connected to the lifting rod 11 via a threaded groove.

[0023] The further advantage of the above is that by rotating the output end of the stepper motor 17, the lifting rod 11 is moved downward, and the flipping support rod 10 is moved outward by the flipping tongue 9, so that the storage box 2 is changed from a vertical state to an inclined state.

[0024] The fixing component further includes an expansion bolt 18 that is inserted into the inner wall of the inner convex plate of the suspension bracket 4.

[0025] The further advantage of adopting the above is that the suspension bracket 4 can be fixed to the wall by the expansion bolt 18, making the device more suitable for home use environment and preventing moisture or rainwater from seeping into the storage box 2, which would cause the energy storage module to age faster or short-circuit due to moisture.

[0026] The counter-force assembly further includes a transmission belt 22 sleeved on one end of the supporting horizontal shaft 21. One end of the transmission belt 22 is inserted into a tension wheel 23. The inner wall of the tension wheel 23 is hinged to the surface of the storage box 2 via a shaft. One end of the tension wheel 23 is engaged with a tilting wheel 24. The inner wall of the tilting wheel 24 is hinged to the surface of the storage box 2 via a shaft. The outer side of the tilting wheel 24 is fixedly connected to the telescopic arm 13.

[0027] The further advantage of the above is that the bottom of the storage box 2 moves outward under the push of the flip support rod 10, and the top traction rod 20 at the top of the storage box 2 is also driven to rotate. Therefore, the top traction rod 20 can rotate through the transmission belt 22 and the tension wheel 23 to drive the flip wheel 24 to rotate. The telescopic arm 13 connected to the flip wheel 24 and its built-in structural components can move the photovoltaic panel 1 to the side of the storage box 2 for placement, so that the photovoltaic panel 1 can be used as a shading or heat preservation cover.

[0028] The external component further includes a mounting base 25 fixed to the surface of the photovoltaic panel 1. A hinge arm 26 is sleeved on the outside of the shaft of the mounting base 25, and one end of the hinge arm 26 is fixed to the surface of the extrusion plate 16.

[0029] A further advantage of the above is that the hinge arm 26 can be connected to the photovoltaic panel 1 via the mounting base 25, providing the necessary technical conditions for the photovoltaic panel 1 to change its tilt angle via the hinge arm 26 and for the photovoltaic panel 1 to change from a flat state to a folded state.

[0030] The top fastening assembly further includes an inner lifting handle 19 fixed to the top of the lifting rod 11 and a top traction rod 20 hinged to the inner side of the suspension bracket 4 via a shaft. A support horizontal shaft 21 is inserted into the inner wall of the top traction rod 20, and both ends of the support horizontal shaft 21 pass through the storage box 2.

[0031] The further advantage of the above is that when the storage box 2 is supported from below by the flip support rod 10, the top of the storage box 2 can move downward under the action of the top traction rod 20, and move the top of the storage box 2 away from the suspension bracket 4. With the help of the flip support rod 10, the storage box 2 is changed from a vertical state to an inclined state, so that the photovoltaic power generation panel 1 can better shade the storage box 2 to reduce sunlight and avoid high temperature, or provide heat preservation effect for the storage box 2 when the temperature is low.

[0032] It is worth noting that after the inward lifting handle 19 moves upward following the lifting rod 11, it can cause one end of the top traction rod 20 to rise, so that the top of the storage box 2 can be fastened to the top of the suspension bracket 4 when it is placed vertically.

[0033] The outer side of the suspension bracket 4 is provided with a matching flip groove 5. The inner wall of the matching flip groove 5 is provided with a following slider 6. One end of the following slider 6 is hinged to a bottom push rod 7. One end of the bottom push rod 7 is fixed with a limit push rod 8. The middle part of the limit push rod 8 is fitted with a flip tongue 9. One end of the flip tongue 9 is fixed with a flip support rod 10. One end of the flip support rod 10 is tightly attached to the surface of the storage box 2. One end of the flip tongue 9 is fitted with a lifting rod 11. Both ends of the lifting rod 11 are connected to the suspension bracket 4 through the built-in groove 12. The inner wall of the telescopic arm 13 is connected to a following rod 15 through a tension spring 14.

[0034] The top end of the follower rod 15 is connected to the compression plate 16 via a reset assembly. Further, the reset assembly includes a T-bolt 27 inserted into the inner wall of the follower rod 15. One end of the T-bolt 27 is fixed to the surface of the compression plate 16, and a follower spring 28 is fixed between the T-bolt 27 and the surface of the follower rod 15.

[0035] The further advantage of the above is that, by following the spring 28, when the extrusion plate 16 slides from the top to the side against the surface of the storage box 2, the extrusion plate 16 moves away from the telescopic arm 13, thereby changing the photovoltaic panel 1 from a flat state to a folded state, and providing shade or heat preservation for the storage box 2.

[0036] The end of the extrusion plate 16 near the storage box 2 has a slope.

[0037] It is worth noting that one end of the extrusion plate 16 is designed with a bevel so that when the extrusion plate 16 slides along the side rib of the storage box 2, the telescopic arm 13 and the following rod 15 can extend and retract, so that the photovoltaic power generation panel 1 is close to the storage box 2. At the same time, the extrusion plate 16 can slide within the following rod 15 to make the photovoltaic power generation panel 1 folded.

[0038] When in use, the stepper motor 17 rotates, causing the lifting rod 11 to move downward along the built-in slide groove 12; When the lifting rod 11 moves down, the sliding block 6 moves down within the rotating groove 5. After the sliding block 6 moves to the bottom of the rotating groove 5, the lifting rod 11 continues to move down. The bottom push rod 7 can drive the rotating tongue 9 from a vertical state to an inclined state through the limiting push rod 8. When the rotating support rod 10 rotates with the rotating tongue 9, the bottom of the storage box 2 can be lifted, so that the storage box 2 changes from a vertical state to an inclined state. During the process of the storage box 2 being pushed by the flip support rod 10, the inward lifting handle 19 moves away from the top traction rod 20, and the top traction rod 20 will flip until the side of the top traction rod 20 is supported at the top of the storage box 2. When the lifting rod 11 moves down, the flip support rod 10 and the top traction rod 20 form a lever system. The two are rigidly connected by the support horizontal shaft 21 to ensure that the top and bottom of the storage box 2 have relative displacement during the tilting process. This displacement is amplified by the transmission belt 22 and converted into the rotational motion of the telescopic arm 13 through the flip wheel 24, ultimately realizing the position transfer and shape change of the photovoltaic power generation panel 1. The rotation of the top traction rod 20 can drive the support horizontal shaft 21 to rotate, which in turn drives the tension wheel 23 to rotate through the transmission belt 22. The rotation of the tension wheel 23 can drive the flip wheel 24 to rotate, thereby moving the photovoltaic panel 1 from the top of the storage box 2 to the side. During the rotation of the flipping wheel 24, the inclined surface of the extrusion plate 16 slides along the top of the storage box 2. The follower rod 15 can be driven to move towards the inner wall of the telescopic arm 13 under the traction of the tension spring 14. When the extrusion plate 16 moves from the top of the storage box 2 to the side, the two extrusion plates 16 will approach each other under the action of the inclined surface. Therefore, the two ends of the photovoltaic power generation panel 1 move relative to each other, which can cause the photovoltaic power generation panel 1 to change from a flat state to a folded position, so as to reduce the sunlight received by the surface of the storage box 2 and prevent high temperature. The photovoltaic power generation panel 1 is folded and has a certain angle with the storage box 2. At high temperature, it can guide heat to dissipate from the corner of the photovoltaic power generation panel 1. At low temperature, since the gap between the photovoltaic power generation panel 1 and the storage box 2 becomes smaller, the heat will remain there for a longer time, forming a heat preservation effect.

[0039] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
