Description

Technical Field

[0001] This invention relates to the field of photovoltaic power generation, and in particular to a foldable photovoltaic container with an energy storage mechanism. Background Technology

[0002] With the increasing prominence of the global energy crisis and environmental problems, solar energy, as a clean and renewable energy source, has received widespread attention for its development and utilization. Photovoltaic equipment, as the core carrier of solar energy utilization, has experienced rapid development in recent years. However, traditional photovoltaic equipment faces many problems that urgently need to be solved in practical applications.

[0003] For example, the patent entitled "A Portable Photovoltaic Array Generator Container and Its Usage Method" (patent application number: CN202211587313.2) discloses a portable photovoltaic array generator container and its usage method, including a foldable photovoltaic power generation unit, a track assembly for the foldable photovoltaic power generation unit to move, and electrical equipment. After multiple foldable photovoltaic power generation units are connected, they can be folded or extended with the assistance of the track assembly. Before the foldable photovoltaic power generation unit is installed, the track assembly needs to be laid first. The track assembly is generally long and made of rigid material, making storage and installation cumbersome.

[0004] Therefore, it is necessary to propose a foldable photovoltaic container with an energy storage mechanism to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a foldable photovoltaic container with an energy storage mechanism to solve the problem that before installing the foldable photovoltaic power generation unit, it is necessary to lay track components first. The track components are generally long and made of rigid materials, which makes storage and installation cumbersome.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a foldable photovoltaic container with an energy storage mechanism, comprising a container body for placing a first storage frame and a second storage frame, wherein photovoltaic modules are folded and stored within the first and second storage frames. The first and second storage frames are both equipped with a winding box at their bottom ends. The winding box is equipped with a winding mechanism. The winding mechanism releases two rails, and a counterweight is fixed to one end of each rail. After the photovoltaic modules are laid out, two track bars clamp the two sides of the photovoltaic modules respectively and support the bottom edge of the photovoltaic modules, so that the photovoltaic modules and the ground are separated by a gap; The top of the track bar is provided with a sliding groove, and both sides of the photovoltaic module are provided with pulleys for sliding in the sliding groove; A heat dissipation component for dissipating heat from the inside of the ground clearance is provided on one side of the winding box.

[0007] Preferably, an insert plate is inserted between the two counterweights, and a ventilation opening is provided in the middle of the insert plate, and a filter screen is provided inside the ventilation opening; Two recessed slots are provided on one side of the winding box, and the counterweight is engaged in the corresponding recessed slot.

[0008] Preferably, the two track bars have L-shaped notches on opposite sides along the length direction, and the track bars are elastic, with the sliding grooves distributed along the length direction of the track bars.

[0009] Preferably, the heat dissipation component includes a heat dissipation fan, and multiple heat dissipation ports are provided between the two embedded slots. The heat dissipation fan is located inside the winding box, and the air outlet of the heat dissipation fan is connected to the multiple heat dissipation ports.

[0010] Preferably, a first side door and a second side door are hinged to one side of the container body. The first side door and the second side door are distributed vertically and open in a direction away from each other. One end of the second side door is attached to the ground and provides inclined support to the bottom of the track.

[0011] Preferably, one end of the container body is hinged to an end section, and the second storage frame slides out of one end of the container body; The container body is equipped with a support rail. The bottom end of the second storage frame is slidably installed on the support rail. A connecting frame is fixed at the bottom of the end of the second storage frame away from the container body. A support leg is rotatably connected inside the connecting frame. The bottom end of the support leg is equipped with a moving wheel.

[0012] Preferably, a second electric push rod is installed between one end of the support rail and the inner wall of the container, and two support rails are provided.

[0013] Preferably, the photovoltaic module includes multiple photovoltaic frames, two adjacent photovoltaic frames are hinged to each other, and a photovoltaic panel is provided inside the photovoltaic frame. L-shaped plates are fixed at both ends of the photovoltaic frame, and the pulley is rotatably connected to the L-shaped plate.

[0014] Preferably, the winding box has two winding slots inside, and each of the two embedded slots has a storage slot for releasing the track bar. The storage slot is connected to the corresponding winding slot, and a winding shaft is rotatably connected between the two winding slots. A motor is fixed inside the winding box, and the drive shaft of the motor is connected to one end of the winding shaft.

[0015] Preferably, the counterweight is provided with an auxiliary handle on the side away from the container body, and the counterweight is telescopically connected to two protruding blocks on the side facing the container body. The top of the counterweight is provided with a fixing screw, which is pressed against the upper surface of the corresponding protruding block.

[0016] Preferably, two adjacent photovoltaic frames are rotatably connected by a hinge shaft and driven to rotate by a servo motor. The servo motor is installed on one side of the photovoltaic frame. When the servo motor starts, it drives the hinge shaft to rotate and drives the photovoltaic frame on the other side to rotate.

[0017] The technical effects and advantages of this invention are as follows: 1. Because the track bar is flexible, it can be stored by rewinding, which facilitates actual installation and reduces the labor intensity of personnel. At the same time, by adjusting the length of the extended and retracted track bar, the deployment requirements of different sites can be met.

[0018] 2. The sides of the photovoltaic modules engage with the L-shaped notches, and the pulleys can slide freely along the sliding grooves at the top of the track bars, enabling the photovoltaic modules to unfold and fold smoothly. At the same time, the L-shaped notches opened along the length of the two track bars on opposite sides allow the sides of the photovoltaic modules to engage precisely, forming a "two-way limiting" with the pulleys and sliding grooves, preventing the photovoltaic modules from tilting or shifting after unfolding.

[0019] 3. After unfolding, the two track bars not only clamp the sides of the photovoltaic module but also support its bottom edge, creating a gap between the photovoltaic module and the ground. This gap avoids wear and moisture caused by direct contact between the photovoltaic module and the ground, and also serves as a natural heat dissipation channel, laying the foundation for subsequent heat dissipation work.

[0020] 4. The track strips can serve as a guide mechanism for the sliding installation of photovoltaic modules, preventing the photovoltaic modules from tilting after being unfolded and ensuring that they are in a straight line. The two track strips also form a protective sleeve on both sides of the photovoltaic modules. Because the track strips are elastic, they can not only adapt to slight ground undulations, but also form a buffer when subjected to external impacts, thus protecting the photovoltaic modules.

[0021] 5. The cooling fan's outlet is connected to multiple heat dissipation vents, forcibly supplying air to the ground clearance beneath the photovoltaic modules, accelerating airflow. As air convects within the gap, it carries the heat generated by the photovoltaic panels and dissipates it through the vents, achieving efficient heat dissipation and effectively solving the problem of efficiency degradation caused by high temperatures in photovoltaic panels.

[0022] 6. The laser head should be tilted downwards, so that the downward beam forms a straight line on the ground to ensure the track remains straight when deployed, avoiding bending or tilting. 7. The first and second storage frames unfold independently from the sides and ends of the container, improving overall operational efficiency. Both the first and second storage frames are used to fold and store photovoltaic modules composed of multiple photovoltaic panels, achieving intensive storage of the photovoltaic modules.

[0035] This invention provides, for example Figures 1 to 11 The foldable photovoltaic container with an energy storage mechanism shown includes a container body 1 for placing a first storage frame 5 and a second storage frame 6, and photovoltaic modules 7 are folded and stored inside the first storage frame 5 and the second storage frame 6. Based on the container body 1, two independent photovoltaic storage and unfolding systems are integrated inside: the first storage frame 5 and the second storage frame 6. Both are used to fold and store the photovoltaic module 7 composed of multiple photovoltaic panels 8, thus realizing the intensive storage of the photovoltaic module 7.

[0036] The side of the container body 1 adopts a layered door design. The first side door 2 and the second side door 3 are hinged to the side of the container body and can be fully opened in the direction away from each other, providing ample space for the lateral unfolding of the photovoltaic module 7. An end door 4 is set at one end of the container body, which facilitates the second storage frame 6 to slide out and unfold from the end of the container body 1. The first storage frame 5 and the second storage frame 6 are deployed from the sides and ends of the container body 1 respectively without interfering with each other, thus improving the overall operational efficiency.

[0037] The first storage frame 5 has upright plates 17 on both sides, and each upright plate 17 has a support plate. The two support plates are rotatably connected to the lower surface of the first side door 2. After the first electric push rod 18 is extended, it can be supported and fixed after the first side door 2 is opened. The extension and retraction of the first electric push rod 18 can complete the opening and closing of the first side door 2.

[0038] The bottom of the first storage frame 5 and the second storage frame 6 are both equipped with a winding box 19. The winding box 19 is equipped with a winding mechanism. The winding mechanism releases two rails 9. One end of each rail is fixed with a counterweight 13. The winding mechanism is used to wind and release the rails 9.

[0039] The winding box 19 has two independent winding slots 33 inside. Each of the two embedded slots 21 has a storage slot 23 for releasing the track bar 9. The storage slot 23 is connected to the corresponding winding slot 33. A winding shaft 35 is rotatably connected between the two winding slots 33. A motor 34 is fixed inside the winding box 19, and the drive shaft of the motor 34 is connected to one end of the winding shaft 35. The motor 34 can be a servo motor to achieve forward and reverse rotation, thereby precisely controlling the release and retraction length of the track bar 9. The track bar 9 is stored by winding, which facilitates actual installation, reduces labor intensity, and allows for adjustment of the release and retraction lengths of the track bar 9 to meet the deployment requirements of different sites.

[0040] An auxiliary handle 14 is provided on the side of the counterweight 13 away from the container body 1. In the actual operation of the present invention, when the first side door 2 and the second side door 3 are opened, the motor 34 can be started to release the track bar 9. At the same time, the personnel pull out the counterweight 13 through the auxiliary handle 14. After the counterweight 13 is pulled out, the track bar 9 is laid on the ground. Then, the folded photovoltaic module 7 can be placed on the two released track bars 9. The photovoltaic module 7 can be laid at a certain angle (i.e., an angled laying between two adjacent photovoltaic spaces) or laid flat on the track bar 9.

[0041] To save storage space for the track bar 9, an inflatable track bar 9 can be used. When rolled up, the air inside the inflatable track bar 9 is expelled, and it is in a deflated state, which is convenient for storage. When in use, the inflatable track bar 9 is inflated to make it bulge, which is convenient for supporting the photovoltaic module 7.

[0042] Specifically, the inflatable track bar 9 has a cavity inside, and an inflation hole can be opened on the side of the end connected to the counterweight 13 to facilitate inflation after being pulled out.

[0043] The counterweight 13 can fix the end of the track bar 9. The counterweight 13 can prevent one end of the track bar 9 from moving by its own weight, and at the same time, it is convenient for personnel to pull out the track bar 9.

[0044] The top of the track bar 9 is provided with a sliding groove 10. Both sides of the photovoltaic module 7 are provided with pulleys 12 for sliding in the sliding groove 10. The photovoltaic module 7 includes multiple photovoltaic frames. Two adjacent photovoltaic frames are hinged to each other, and photovoltaic panels 8 are provided in the photovoltaic frames. L-shaped plates 11 are fixed at the top of both ends of the photovoltaic frames. The L-shaped plates 11 are fixed to the photovoltaic frames by bolts, and the pulleys 12 are rotatably connected in the L-shaped plates 11.

[0045] The pulleys 12 of the photovoltaic module 7 are placed into the sliding grooves 10. The pulleys can move freely along the sliding grooves 10 of the track 9, realizing the smooth unfolding and folding of the photovoltaic module, while limiting the photovoltaic module 7 to prevent tilting. Adjacent photovoltaic frames are connected by hinges, which can be folded flexibly. When unfolded, they slide along the sliding grooves 10 via the pulleys 12.

[0046] Both track bars 9 have L-shaped notches 24 on their opposite sides along their length, and sliding grooves 10 are distributed along the length of the track bars 9. The side of the photovoltaic module 7 engages within the L-shaped notches 24, and the pulley 12 can slide freely along the sliding grooves 10 at the top of the track bar 9, enabling the photovoltaic module 7 to unfold and fold smoothly. At the same time, the L-shaped notches 24 on the opposite sides of the two track bars 9 allow the side of the photovoltaic module 7 to engage precisely within them, forming a "two-way limiting" with the pulley 12 and the sliding grooves 10, preventing the photovoltaic module 7 from tilting or shifting after unfolding.

[0047] Once deployed, the two track bars 9 not only clamp the photovoltaic module 7 on both sides but also support its bottom edge, creating a gap between the photovoltaic module 7 and the ground. This gap avoids wear and moisture caused by direct contact between the photovoltaic module and the ground, and also serves as a natural heat dissipation channel, laying the foundation for subsequent heat dissipation work.

[0048] Furthermore, the track bar 9 can serve as a guide mechanism for the sliding installation of the photovoltaic module 7, preventing the photovoltaic module 7 from tilting after it is unfolded and ensuring that it is in a straight line. The two track bars 9 also form a protective sleeve on both sides of the photovoltaic module 7. Because the track bar 9 is elastic, it can not only adapt to slight ground undulations, but also form a buffer when subjected to external impact, thus protecting the photovoltaic module 7.

[0049] A plate 15 is inserted between the two counterweights 13. A vent 16 is provided in the middle of the plate 15, and a filter screen is installed inside the vent 16. Slots 27 are provided on opposite sides of the two counterweights 13. The two ends of the plate 15 are inserted into the corresponding slots 27. The air blown out by the heat dissipation component can be discharged from the vent 16, which not only ensures that the air in the ground clearance is discharged, but also prevents dust and debris from entering. At the same time, the plate 15 can fix the two counterweights 13 to avoid the problem of non-parallelism between the two counterweights 13, and can increase the stability between the two counterweights 13. When not in use, the plate 15 can be placed inside the container body 1.

[0050] The insertion plate 15 can block and protect one end of the photovoltaic module 7, and play a limiting role.

[0051] A heat dissipation assembly for cooling the interior of the ground clearance gap is provided on one side of the winding box 19. The heat dissipation assembly includes a cooling fan, and multiple heat dissipation vents 20 are provided between the two embedded slots 21. The cooling fan is located inside the winding box 19, and the air outlet of the cooling fan is connected to the multiple heat dissipation vents 20, forcibly supplying air to the ground clearance gap below the photovoltaic module 7 to accelerate air circulation. After the air forms convection within the gap, it carries the heat generated by the operation of the photovoltaic panel 8 and is discharged through the ventilation vents 16 of the insertion plate 15, achieving efficient heat dissipation and effectively solving the problem of efficiency degradation of the photovoltaic panel 8 due to high temperature.

[0052] It should be noted that the photovoltaic modules 7 inside the second storage frame 6 can also be supported and unfolded by pulling out the track bar 9. Furthermore, the bottom end of the second storage frame 6 can be hinged to a support plate (not shown in the figure) that opens in the same direction as the second side door 3. One end of the support plate contacts the ground, forming an inclined support to support the unfolded photovoltaic modules 7. Since this is existing technology, it will not be described in detail.

[0053] Two recessed slots 21 are provided on one side of the winding box 19, and the counterweight 13 is fitted into the corresponding recessed slot 21. A laser head 22 is provided in the recessed slot 21. The laser head 22 is inclined downward to irradiate, and its inclined downward beam forms a straight line on the ground to ensure that the track bar 9 remains straight when it is unfolded, and avoids bending or tilting.

[0054] One end of the second side door 3 is attached to the ground and provides inclined support to the bottom of the track strip 9.

[0055] The container body 1 is equipped with a support rail 31. The bottom end of the second storage frame 6 is slidably installed on the support rail 31. The bottom end of the second storage frame 6 away from the container body 1 is fixed with a connecting frame 28. The connecting frame 28 is rotatably connected with a support leg 29. The bottom end of the support leg 29 is equipped with a movable wheel 30. The support leg 29 can be unfolded to support the bottom after the second storage frame 6 slides out.

[0056] A second electric push rod 32 is installed between one end of the support rail 31 and the inner wall of the container body 1. There are two support rails 31. The second electric push rod 32 can drive one end of the support rail 31 to extend out of the container body 1, so that the support rail 31 can support the sliding second storage frame 6. At the same time, the second storage frame 6 can also slide on the extended support rail 31 to increase the sliding length of the second storage frame 6.

[0057] The counterweight 13 has two telescopically connected extension blocks 25 on one side of the container body 1. The top of the counterweight 13 is provided with a fixing screw 26, which is pressed against the upper surface of the corresponding extension block 25. The extension block 25 can be pressed and fixed by the fixing screw 26. The extension block 25 can enhance the stability of the counterweight 13 in contact with the ground, increase the contact area with the ground, and improve the friction.

[0058] The container 1 has a reserved space for installing energy storage batteries, which can be seamlessly connected with photovoltaic modules 7 to form an integrated "power generation-energy storage" system. With high power generation efficiency and stable operation, it can realize the instant storage and flexible use of electrical energy, playing an important role in scenarios such as power outage emergencies and off-grid power supply, and improving the autonomy and reliability of energy utilization.

[0059] The entire outer surface of container 1 is coated with a polyurea elastomer coating system. This coating is formed by the on-site spraying and curing of isocyanate components and amino compound components, with the thickness controlled within the range of 2.0±0.2mm, forming a continuous and seamless elastic protective layer.

[0060] This polyurea coating system achieves both corrosion protection and explosion-proof functions through the following technical features: Corrosion resistance: The coating has an adhesion of ≥8MPa to the steel surface and has excellent resistance to chemical media corrosion. It can withstand acid and alkaline environment corrosion in the pH range of 3-11. In the salt spray test, it can achieve more than 5000 hours without rust or peeling, meeting the requirements for use in C5-M high corrosion environments.

[0061] Explosion-proof performance: The coating has a Shore hardness of ≥85D, an elongation at break of ≥300%, and a tensile strength of ≥25MPa. When subjected to external impact, it can absorb more than 80% of the impact energy through elastic deformation. When unexpected pressure fluctuations occur inside the container, it can buffer the pressure impact through its own extensibility, preventing the container from brittle fracture due to instantaneous force concentration.

[0062] Construction process: High-pressure airless spraying technology is adopted, the coating curing speed is ≤10 seconds, and it can be applied in an environment of -10℃ to 40℃. It forms a molecular-level bond with the steel surface of the container body, and the coating does not contain volatile organic compounds (VOCs), which meets environmental protection requirements.

[0063] Durability: The coating has excellent resistance to ultraviolet aging. After 1000 hours of QUV aging test, the color difference ΔE ≤ 3 and the tensile strength retention rate ≥ 85%, which can ensure an effective protection life of more than 10 years in outdoor exposure. Example

[0064] like Figure 1 , 10 As shown in Figure 11, two adjacent photovoltaic frames are rotatably connected by a hinge shaft. A hinge block is installed on the side of the photovoltaic frame closest to the hinge shaft. The hinge block is located on the hinge shaft. Space can be reserved at the hinge side of the adjacent photovoltaic frames to install a servo motor 37, ensuring that the output shaft of the servo motor 37 is coaxial with the hinge shaft. When the servo motor 37 is activated, the corresponding photovoltaic frames can be actively unfolded. Two photovoltaic frames that unfold via the servo motor 37 form a group. The two groups of photovoltaic frames are hinged on opposite sides, and abutment blocks 36 can be added to the opposite sides of the two groups of photovoltaic frames. When the two adjacent photovoltaic frames unfold, the two abutment blocks 36 contact each other, forming a limit. The angle formed between the photovoltaic frames can be achieved by using abutment blocks 36 of different shapes or tangential angles according to the unfolding needs of the photovoltaic frames, resulting in an M-shaped distribution of the two groups of photovoltaic frames.

[0065] A traveling mechanism is provided on the side of the hinge shaft near the servo motor 37. The traveling mechanism includes a drive gear bearing, two driven wheels, a drive frame 39, and a wear-resistant belt 38. The drive gear bearing and driven wheels are triangular in shape. The wear-resistant belt 38 is provided on the outer side of the drive gear bearing and driven wheels. The inner side of the wear-resistant belt 38 has teeth. The drive gear bearing is driven by the hinge shaft, and then transmitted to the driven wheels through the wear-resistant belt 38, forming a stable mechanical transmission path to ensure the smooth and reliable unfolding and retraction of the photovoltaic frame. Since this is existing technology, it will not be described in detail.

[0066] Auxiliary wheels can also be added to both sides of the photovoltaic frame to facilitate movement on the ground after the photovoltaic frame is unfolded, without the need for additional tracks. Since the servo motor 37 can rotate in both directions, the photovoltaic frame can automatically extend and retract.

[0067] When the photovoltaic frame unfolds to the preset position, rigid contact is formed between the limiting blocks 36, precisely limiting the unfolding angle of the frame to 140° through mechanical limiting, with an angle control accuracy of ±0.5°. This 140° unfolding tilt angle is the optimal light-receiving angle optimized through simulation. It is designed based on the variation law of solar altitude angle in a specific latitude region, which can maximize the amount of sunlight received by the photovoltaic panel and the effective irradiation time in different seasons and at different times of the year.
