Description

Technical Field

[0001] The present invention relates to the technical field of power generation devices, and particularly to a power generation device for an outdoor air conditioner. Background Art

[0002] When selecting a power generation device for an outdoor air conditioner, factors such as the usage environment, power consumption requirements, and cost need to be comprehensively considered. For example, for outdoor monitoring stations in desert areas and outdoor operation sites in plateau areas, a solar power generation device can be given priority. It can utilize the abundant solar energy resources to stably supply power to the air conditioner when the sunlight is sufficient, and it is pollution-free and has a low maintenance cost. In addition, when air conditioning cooling is required in high temperatures in summer, the solar radiation is strong and the power generation capacity is also stronger, which has a high seasonal matching degree with the usage requirements of the air conditioner. The solar power generation device mainly consists of parts such as solar panels, a controller, an inverter, and a bracket system. Since the solar power generation device is fixed by brackets, the flexibility of the power generation device in use is poor, resulting in a large occupied space for the solar power generation device and the lack of a function of storage and folding, which affects the operation when used for outdoor air conditioner power generation. Therefore, we propose a power generation device for an outdoor air conditioner. Summary of the Invention

Detailed implementation manners

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Example 1: Please refer to Figure 1 - Figure 14 , a power generation device for an outdoor air conditioner shown in the figure includes: a box body 1 and a main photovoltaic panel 2 arranged on the box body 1; it also includes: a mounting plate b3 rotatably connected to the box body 1 through a rotating rod 11, a secondary photovoltaic panel 4 is mounted on the mounting plate b3, an adjustment expansion unit 5 adapted to the main photovoltaic panel 2 and the secondary photovoltaic panel 4 is arranged in the box body 1, the adjustment expansion unit 5 is used to flip the secondary photovoltaic panel 4 and lift the main photovoltaic panel 2, and; a cleaning unit 6 is arranged in the box body 1, the cleaning unit 6 is used to clean dust attached to the surface of the main photovoltaic panel 2, an inverter 7 and a controller 8 are arranged in the box body 1, a handle 53 is rotatably connected to the box body 1 through a mounting block 42, the size of the main photovoltaic panel 2 is larger than that of the secondary photovoltaic panel 4, but the sum of the sizes of the two secondary photovoltaic panels 4 is larger than that of the main photovoltaic panel 2; It should be noted that the main photovoltaic panel 2 and the auxiliary photovoltaic panel 4 are responsible for converting solar energy into direct current, and the controller 8 mainly functions to manage and control the electrical energy output by the solar panels. The inverter converts the generated direct current into alternating current. The main photovoltaic panel 2 and the auxiliary photovoltaic panel 4 are mainly made of semiconductors. When sunlight shines on the panels, the photon energy is transferred to the electrons in the semiconductors, causing the electrons to transition into free electrons, thereby generating current. This process is based on the photoelectric effect, that is, the phenomenon that matter absorbs photon energy to generate electricity. This is a conventional setting in the field and will not be described in detail here. In addition, when the outdoor air conditioner is generating electricity, the main photovoltaic panel 2 and the auxiliary photovoltaic panel 4 are used to generate electricity. By adjusting the setting of the expansion unit 5, when the main photovoltaic panel 2 is adjusted and raised to an appropriate position, the two auxiliary photovoltaic panels 4 will be rotated 180 degrees in a linked manner, so that the main photovoltaic panel 2 and the auxiliary photovoltaic panel 4 can be on the same horizontal plane and receive sunlight together. This structure not only has efficient power generation capabilities, but also has a convenient storage function due to its unique design. It is not only very convenient to carry and use, but also effectively solves the inconvenience faced by traditional brackets when carrying, greatly improving the portability and practicality of the outdoor air conditioner. In addition, when the main photovoltaic panel 2 and the secondary photovoltaic panel 4 are not used for power generation, the expansion assembly can be adjusted to cleverly store the main photovoltaic panel 2 and the secondary photovoltaic panel 4 inside the box body 1. This not only saves space but also protects the photovoltaic panels from damage by the external environment. At the same time, the cleaning unit 6 is activated to thoroughly clean the dust adhering to the surface of the main photovoltaic panel 2. This process is crucial because the accumulation of dust will significantly reduce the power generation efficiency of the photovoltaic panel and affect its performance. Through such maintenance measures, it can be ensured that the main photovoltaic panel 2 is in the best working state before the next power generation work starts, thus maximizing the power generation effect.

[0021] Furthermore, as shown in Figure 6 , Figure 9 and Figure 10 , specifically, the cleaning unit 6 includes: at least two guide rails 21 are fixed inside the box body 1. A threaded rod 22 is rotatably connected to one of the guide rails 21. A slider 23 and a threaded sleeve 24 are respectively slidably connected inside the two guide rails 21, and the threaded sleeve 24 is threadedly connected to the threaded rod 22. A brush roller 25 is rotatably connected between the slider 23 and the threaded sleeve 24. A small gear 26 is fixed on the brush roller 25. A rack b 27 meshing with the small gear 26 is fixed on the box body 1. A driving motor 28 is fixed outside the box body 1. A spur gear a 29 is fixed on both the output shaft of the driving motor 28 and the threaded rod 22, and the two spur gears a 29 are meshingly connected; Among them, a protective shell 54 is fixed on the box body 1. The two spur gears a 29 are located inside the protective shell 54. By adding the protective shell 54, effective protection measures can be provided for the two spur gears a 29, avoiding the damage of the spur gears a 29 due to long-term exposure to the outside, and preventing the phenomenon of accidental contact with the spur gears a 29 during use; It should be noted that through the setting of the cleaning unit 6, when the main photovoltaic panel 2 and the secondary photovoltaic panel 4 are both safely stored inside the box body 1, the brush roller 25 will naturally rotate while performing a translational motion to ensure thorough cleaning of the dust adhering to the surface of the main photovoltaic panel 2. This efficient cleaning method can effectively avoid the decrease in power generation efficiency caused by excessive dust accumulation, thus ensuring that the photovoltaic panel can continuously operate in the best state and bring stable power output to users; Cleaning principle of the main photovoltaic panel 2 by the cleaning component: Driven by the driving motor 28, the two spur gears a29 are meshed and driven, so as to drive the threaded rod 22 to rotate synchronously. By using the threaded transmission between the threaded rod 22 and the threaded sleeve 24, the threaded sleeve 24 is forced to translate along the guide rail 21, thereby driving the brush roller 25 to translate synchronously. With the meshing setting of the pinion 26 and the rack b27, the purpose that the brush roller 25 rotates when translating can be achieved. Then, the surface of the main photovoltaic panel 2 is continuously cleaned by the brush roller 25.

[0022] In this solution, when using the main photovoltaic panel 2 and the secondary photovoltaic panel 4 for power generation work: First of all, driven by the cylinder 9, the mounting plate a10 and the main photovoltaic panel 2 rise synchronously, driving the transmission plate 15 to move synchronously, causing the transmission plate 15 to come into contact with the toothed plate a14, thereby driving the toothed plate a14 to rise along the groove a16 under force. By using the meshing transmission between the toothed plate a14 and the transmission gear 12, the mounting plate b3 and the secondary photovoltaic panel 4 are flipped 180°, so that the main photovoltaic panel 2 and the secondary photovoltaic panel 4 are kept in the same horizontal plane state; At the same time, when the mounting plate a10 moves upward, it drives the toothed plate b37 to move synchronously. By using the meshing transmission between the toothed plate b37 and the spur gear c38, the rotating shaft 34 is forced to rotate, thereby driving the spur gear b35 to rotate synchronously. And by using the meshing transmission between the spur gear b35 and the rack a36, the mounting frame 33 and the universal wheel 30 are forced to contract into the box body 1; After that, when the main photovoltaic panel 2 and the secondary photovoltaic panel 4 need to be stored, the main photovoltaic panel 2 is driven by the cylinder 9 to descend into the box body 1, and then the transmission plate 15 is separated from the toothed plate a14. By using the elastic action of the spring a19, the toothed plate a14 is driven to move back to its original position. With the meshing transmission between the toothed plate a14 and the transmission gear 12, the purpose of driving the secondary photovoltaic panel 4 to flip back to its original position is achieved. At the same time, the universal wheel 30 is driven to extend out of the box body 1.

[0023] Embodiment 2: Refer to Figure 4 - Figure 7 As shown, this embodiment further explains Embodiment 1, and the difference lies in the disclosure of the lifting and flipping methods of the main photovoltaic panel 2 and the secondary photovoltaic panel 4.

[0024] Specifically, the adjustment and expansion unit 5 includes: at least two cylinders 9 are fixed inside the box body 1, an installation plate a10 is fixed at the output end of the cylinder 9, and the main photovoltaic panel 2 is installed on the installation plate a10. A transmission gear 12 is fixed on the rotating rod 11. A channel 13 is opened on the box body 1, and a toothed plate a14 engaged with the transmission gear 12 is slidably connected inside the channel 13. A transmission plate 15 is fixed on the installation plate a10. A groove a16 is opened on the box body 1, and the transmission plate 15 is slidably connected inside the groove a16. At least two mounting sleeves 17 are fixed on the toothed plate a14, and a guide rod 18 is jointly fixed on the two mounting sleeves 17. The guide rod 18 is slidably penetrated through the box body 1. A spring a19 is sleeved on the surface of the guide rod 18. One end of the spring a19 is fixed to one of the mounting sleeves 17, and the other end of the spring a19 is fixed with a mounting ring 20 slidably sleeved on the outer surface of the guide rod 18. By setting the mounting ring 20, the limiting effect on the guide rod 18 and the toothed plate a14 can be achieved, preventing the toothed plate a14 from moving too far and disengaging from the transmission gear 12. When the spring a19 fails to drive the secondary photovoltaic panel 4 to reset properly, the toothed plate a14 can be manually pressed or the secondary photovoltaic panel 4 can be manually intervened to be flipped for resetting; Among them, several slide rails 39 are fixed inside the box body 1, and the other side wall of the slide rail 39 is fixed to the bottom surface of the installation plate a10. By adding the slide rails 39, not only can the guiding function be provided for the lifting of the main photovoltaic panel 2, but also it can ensure that the main photovoltaic panel 2 keeps a relatively stable state during the lifting movement, avoiding the situation of shaking when the main photovoltaic panel 2 is lifted; It should be noted that through the setting of the adjustment and expansion unit 5, when power generation work needs to be carried out, the main photovoltaic panel 2 and the secondary photovoltaic panel 4 can be efficiently and stably adjusted to the same horizontal plane state. With the cooperation of the main photovoltaic panel 2 and the secondary photovoltaic panel 4, the power generation work efficiency can be improved to a certain extent. And when power generation work is not needed, the main photovoltaic panel 2 and the secondary photovoltaic panel 4 can be completely stored inside the box body 1, thereby protecting the main photovoltaic panel 2 and the secondary photovoltaic panel 4; It should also be noted that by adopting an innovative design, that is, effectively storing and protecting the main photovoltaic panel 2 and the secondary photovoltaic panel 4, the problems existing in the traditional solar power generation device can be significantly improved. These problems are mainly reflected in the way of fixing with brackets, which makes the equipment difficult to carry and quite inconvenient to operate when used outdoors.

[0025] Furthermore, the box body 1 is provided with a plurality of universal wheels 30, and the box body 1 is provided with a retraction mechanism 31. The retraction mechanism 31 includes: a plurality of circular grooves 32 are opened on the box body 1, a mounting frame 33 is provided in the box body 1, and the universal wheels 30 are fixed to the mounting frame 33, at least two rotating shafts 34 are rotatably connected to the box body 1, a spur gear b35 is fixed to the rotating shaft 34, a rack a36 meshing with the spur gear b35 is fixed in the mounting frame 33, a toothed plate b37 is fixed to the bottom surface of the mounting plate a10, and a spur gear c38 meshing with the toothed plate b37 is fixed to the rotating shaft 34; Among them, a plurality of circumferentially distributed limiting rods 46 are fixed to the universal wheel 30, and a limiting groove 47 is provided on the box body 1. The limiting rods 46 are adapted to the limiting groove 47, and the central axis of the universal wheel 30 and the central axis of the circular groove 32 are arranged in a collinear manner. The four limiting rods 46 realize the limiting function for one universal wheel 30, effectively preventing the universal wheel 30 from moving too far. In addition, when the universal wheel 30 is used, the setting of the limiting rods 46 engaging with the limiting groove 47 can significantly improve the stability of the universal wheel 30 when in use. In addition, a plurality of rubber rings are fixed to the bottom of the box body 1, and the central axis of the rubber ring is collinear with the central axis of the circular groove 32. The additional rubber rings can provide a cushioning effect for the box body 1 when the universal wheel 30 is stored, thereby preventing the box body 1 from being damaged by direct contact with the ground. At the same time, several frames 48 are fixed in the box body 1, and a slide 49 is fixed on the mounting frame 33. The slide 49 is slidably connected to the frame 48. The bottom surface of the mounting plate a10 contacts one side of the frame 48. The cross section of the slide 49 is T-shaped. A pulley 51 is rotatably connected to the slide 49 through an additional plate 50. A slide groove 52 is opened in the frame 48, and the pulley 51 is slidably connected in the slide groove 52. Both side walls of the pulley 51 are chamfered. It should be noted that the addition of the frame 48 and the slide plate 49 can significantly improve the stability of the mounting frame 33 and the universal wheel 30 during lifting and lowering, thereby preventing shaking caused by insufficient stability during the lifting and lowering operation of the universal wheel 30, thereby ensuring that the lifting and lowering movement of the universal wheel 30 maintains sufficient stability for normal lifting and lowering. At the same time, it is worth mentioning that the addition of the pulley 51 and the slide 52 further improves the smoothness of the lifting and lowering operation of the movable plate, the mounting frame 33 and the universal wheel 30, thereby preventing the occurrence of jamming. It should be noted that through the linkage between the contraction component and the adjustment and expansion unit 5, it can be ensured that when the main photovoltaic panel 2 and the auxiliary photovoltaic panels 4 are used for power generation work, multiple universal wheels 30 can automatically contract and hide inside the box body 1. This design not only ensures the occupation stability of the main photovoltaic panel 2 and the auxiliary photovoltaic panels 4 during the power generation process, but also when these photovoltaic panels are not used for power generation, the universal wheels 30 can reset to their initial state. Such a reset function makes the device easy to push and move, thus providing great convenience for users. Therefore, while ensuring the power generation efficiency, this device also takes into account flexibility and portability, enabling users to easily push the device to any desired position when needed.

[0026] Embodiment 3: Refer to Figure 1 and Figure 2 As shown, this embodiment further illustrates other embodiments, and the difference lies in the limiting method for the two auxiliary photovoltaic panels 4 when they are in the storage state.

[0027] Furthermore, a limiting member 40 is provided on the box body 1. The limiting member 40 is used for angular limitation of the two auxiliary photovoltaic panels 4. The limiting member 40 includes: a groove b41 is formed on the box body 1, a mounting block 42 is fixed on the box body 1, and a rod body 43 slidably penetrates through the mounting block 42. One end of the rod body 43 is fixed with a limiting plate 44, and the limiting plate 44 is slidably connected in the groove b41. A spring b45 is sleeved on the surface of the rod body 43. One end of the spring b45 is fixed to the limiting plate 44, and the other end of the spring b45 is fixed to the mounting block 42. The two auxiliary photovoltaic panels 4 are in contact with the limiting plate 44; It should be noted that through the addition of the limiting member 40, a bearing and lifting effect can be formed on the bottom surfaces of the two auxiliary photovoltaic panels 4, preventing the two auxiliary photovoltaic panels 4 from being damaged due to lack of support and breakage caused by long-term non-use in the storage state; It should also be noted that when the main photovoltaic panel 2 rises, the main photovoltaic panel 2 comes into contact and extrusion with the limiting plate 44. Using the extrusion effect, the limiting plate 44 is forced to move along the groove b41. At this time, the spring b45 is under extrusion. When the main photovoltaic panel 2 descends, using the elastic effect of the spring b45, the limiting plate 44 can be rebounded and reset to its initial position, and the top surface of the limiting plate 44 forms a support and limitation for the auxiliary photovoltaic panel 4.

[0028] The main photovoltaic panel 2, the auxiliary photovoltaic panels 4, the driving motor 28, and the cylinder 9 can all be purchased on the market and are separately equipped with power supplies, which are mature technologies in this field and have been fully disclosed, so they will not be repeated in the specification.

[0029] It should be noted that in this document, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variation thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.
