Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic solar energy, and specifically relates to a household photovoltaic energy storage device. Background Art

[0002] As the global energy crisis intensifies and environmental awareness increases, solar energy, as a clean, renewable energy source, has attracted more and more attention. As an important part of the solar power generation system, the performance of household photovoltaic energy storage devices directly affects the efficiency and stability of solar power generation.

[0003] However, existing household photovoltaic energy storage devices have certain limitations in design and function, especially the problem of being unable to store photovoltaic panels. Existing household photovoltaic energy storage devices usually adopt a fixed installation method, that is, photovoltaic panels are installed on the roof or the ground and connected to the energy storage device through cables. This installation method requires a certain amount of space, which will affect the use of other purposes for limited household space. Secondly, non-storable photovoltaic panels are more susceptible to damage when bad weather (such as heavy rain, hail, etc.) comes. Once the photovoltaic panel is damaged, it will not only affect the power generation efficiency, but may also require expensive repair or replacement costs. Based on the above problems, this application document proposes a household photovoltaic energy storage device to improve the above problems. Utility Model Content

[0025] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0026] like Figures 1 to 4 As shown, a household photovoltaic energy storage device includes a storage box 10, wherein the interior of the storage box 10 is equipped with a lifting mechanism 15, and a support plate 25 is provided at the upper end of the lifting mechanism 15 and located inside the storage box 10, and two pillars 26 are fixed on both sides of the upper end of the support plate 25, and the two pillars 26 on the upper end of the support plate 25 and located on one side are rotatably connected to a second rotating rod 27, and a photovoltaic panel 28 is fixed on the second rotating rod 27, and support rods 29 are fixed at both ends of the photovoltaic panel 28 close to the second rotating rod 27, and a threaded sleeve 24 is fixed to the upper end of the middle part of the support plate 25.

[0027] In the above embodiment, the photovoltaic panel 28 is rotated, and the photovoltaic panel 28 rotates along the second rotating rod 27. When the photovoltaic panel 28 rotates to a suitable illumination angle, the support rod 29 is limited by the positioning rod 30, so that the photovoltaic panel 28 can be fixed.

[0028] Furthermore, the support rod 29 is C-shaped, and a plurality of first circular through holes are evenly formed on the outer side of the support rod 29 .

[0029] In the above embodiment, the C-shaped design can improve the strength of the support rod 29, making it more able to withstand heavy pressure. At the same time, the positioning rod 30 can penetrate the first circular through hole on the support rod 29 to limit the support rod 29.

[0030] like Figure 4 and Figure 5 As shown, first square grooves are formed at both ends of the support plate 25, and second rollers 23 are fixed in the two first square grooves. Second square grooves are formed at both ends of the storage box 10, and the second rollers 23 are rollingly connected in the second square grooves.

[0031] In the above embodiment, when the support plate 25 rises, the second roller 23 is rolled and connected in the second square groove. The rolling connection between the second roller 23 and the second square groove can reduce the friction caused by direct contact, thereby reducing wear and extending the service life of the equipment. At the same time, the rolling connection is less noisy than the sliding connection, which is conducive to improving the working environment.

[0032] like Figure 7 and Figure 8 As shown, a second circular through hole is opened inside the upper end of the pillar 26, an annular groove is opened in the middle of the second circular through hole, and the radius of the annular groove is larger than the radius of the second circular through hole, a positioning rod 30 is slidably connected in the second circular through hole, a retaining ring 31 is fixed on the outer side of the positioning rod 30 and located in the annular groove, a spring 32 is arranged in the annular groove and at one end of the retaining ring 31 close to the positioning rod 30, and the spring 32 is fixed to the inside of the pillar 26.

[0033] In the above embodiment, the positioning rod 30 is pulled, and because the retaining ring 31 is fixed on the outer side of the positioning rod 30, the retaining ring 31 starts to move, and the retaining ring 31 squeezes the spring 32 when it moves, and the positioning rod 30 contracts at the same time. When the positioning rod 30 is pulled to a certain position, it no longer moves. At this time, the photovoltaic panel 28 can be rotated. When it is adjusted to a suitable angle, the positioning rod 30 is no longer pulled. The positioning rod 30 starts to move toward one end of the photovoltaic panel 28 under the action of the spring 32. Because a number of first circular through holes are evenly opened on the outer side of the support rod 29 and are compatible with the positioning rod 30, the support rod 29 can be limited when the positioning rod 30 moves, thereby fixing the photovoltaic panel 28.

[0034] The lifting mechanism 15 includes a bearing 16, a first rotating rod 17, a worm wheel 18, a threaded rod 19, a worm 20 and a handwheel 21. The bearing 16 is fixed to the inside of the storage box 10, the first rotating rod 17 is fixed to the upper end of the bearing 16, the worm wheel 18 is fixed to the outer side of the first rotating rod 17, the threaded rod 19 is fixed to the upper end of the first rotating rod 17, and the threaded sleeve 24 is adapted to the threaded rod 19. The worm 20 passes through the inside of the storage box 10, and one side of the worm 20 is meshed and connected with the outer side of the worm wheel 18. The handwheel 21 is fixed to the side of the worm 20 away from the worm wheel 18.

[0035] In the above embodiment, by rotating the handwheel 21, the worm 20 is driven to rotate when the handwheel 21 rotates, and the worm wheel 18 is driven to rotate when the worm 20 rotates. The worm wheel 18 is fixed to the outside of the first rotating rod 17, and the bottom end of the first rotating rod 17 is rotatably connected to the bearing 16, so when the worm wheel 18 rotates, the first rotating rod 17 rotates, and at the same time, the first rotating rod 17 drives the threaded rod 19 to rotate, the threaded rod 19 and the threaded sleeve 24 are threadedly connected, and the threaded sleeve 24 and the support plate 25 are fixedly connected, so when the threaded rod 19 rotates, the support plate 25 rises.

[0036] Positioning pins 11 are fixed at both ends of the upper end of the storage box 10, the outer side of one positioning pin 11 is rotatably connected to a first cover plate 12, one end of the first cover plate 12 is hingedly connected to a second cover plate 13, and first rollers 14 are fixed at the four end corners of the lower end of the storage box 10.

[0037] In the above embodiment, the first cover plate 12 rotates on the outside of the positioning pin 11. When the first cover plate 12 needs to be opened, the first cover plate 12 is rotated half a circle by rotating the first cover plate 12. Because the second cover plate 13 is hinged to the first cover plate 12, the second cover plate 13 is downward, avoiding the second cover plate 13 occupying space in the horizontal direction.

[0038] The working principle of the utility model is:

[0039] During operation, the support plate 25 can be raised by turning the hand wheel 21, and at the same time, the second rollers 23 fixed at both ends of the support plate 25 are rollingly connected in the second square groove. When the support plate 25 rises to a certain height, it will no longer rise. At this time, the positioning rod 30 is pulled, and when the photovoltaic panel 28 on one side is rotated to a suitable angle, the photovoltaic panel 28 is fixed to the pillar 26 through the positioning rod 30. When the photovoltaic panel 28 needs to be stored, the positioning rod 30 is pulled, and the photovoltaic panel 28 can be rotated to the upper end of the support plate 25. The hand wheel 21 is turned to lower the lifting mechanism 15. At this time, the photovoltaic panel 28 is stored in the storage box 10.

[0040] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
