DETAILED DESCRIPTION

[0031] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0032] like Figures 1 to 10 As shown, a photovoltaic panel supporting device for photovoltaic energy storage provided by the present invention includes a water tank 1 and a vacuum heat collecting tube 3, the water tank 1 is fixedly mounted on a base 2, there are a plurality of vacuum heat collecting tubes 3, and the plurality of vacuum heat collecting tubes 3 are arranged in an array on one side of the water tank 1 and are connected to the water tank 1, the vacuum heat collecting tube 3 is used to heat the water in the water tank 1 to a target temperature, and the photovoltaic panel supporting device for photovoltaic energy storage also includes:

[0033] A photovoltaic assembly 4, wherein the photovoltaic assembly 4 comprises a circumferential shift assembly, a photovoltaic panel 43 and an extension assembly 44, wherein the photovoltaic panel 43 is arranged on one circumferential side of the vacuum heat collecting tube 3, and the photovoltaic panel 43 is arranged corresponding to the vacuum heat collecting tube 3, wherein the photovoltaic panel 43 comprises a first side photovoltaic panel 432, a main photovoltaic panel 433 and a second side photovoltaic panel 434, wherein one end of the main photovoltaic panel 433 away from the water tank 1 is transmission-connected with the circumferential shift assembly, one side end of the main photovoltaic panel 433 is rotationally connected with the first side photovoltaic panel 432, and the other side end of the main photovoltaic panel 433 is rotationally connected with the second side photovoltaic panel 434, wherein the circumferential shift assembly is used to control the conversion of the photovoltaic panel 43 between the initial position and the heat collecting position, and one end of the first side photovoltaic panel 432 and the second side photovoltaic panel 434 away from the circumferential shift assembly are transmission-connected with the extension assembly 44 respectively;

[0034] When the photovoltaic panel 43 is located at the heat collection position, driven by the extension assembly 44, the first side photovoltaic panel 432 and the second side photovoltaic panel 434 swing outward to the heat collection position respectively, and the swing directions of the first side photovoltaic panel 432 and the second side photovoltaic panel 434 are opposite.

[0035] In the above embodiment, a water inlet pipe 11 and a water outlet pipe 12 are provided on the side of the water tank 1. The user can add water to the water tank 1 through the water inlet pipe 11, and take water from the water tank 1 through the water outlet pipe 12. When the vacuum collector tube 3 absorbs solar energy and heats the water in the water tank 1 to the target temperature, under the control of the controller, the circumferential shift component is driven to transmit the main photovoltaic panel 433 to rotate it from the initial position to the heat collection position, so that in the same illumination area, the photovoltaic panel 43 can be used to further collect and store solar energy without the need to additionally build a working bearing equipment for the photovoltaic panel 43, thereby making full use of the limited space area of ​​the residents. In addition, after the water in the water tank is heated to the target temperature, the photovoltaic panel 43 continues to absorb and store subsequent solar energy, for example, for powering small household appliances, thereby making full use of solar energy.

[0036] It should be noted that the target temperature of the water in the water tank can be adjusted according to user needs. For example, in winter, the demand for hot water is high, so the target temperature can be set to 60-70°C, while in summer, the demand for hot water is low, so the target temperature can be set to 35-45°C. There is no limitation here.

[0037] Among them, the working principle of the vacuum heat collection tube 3 of the device of the present invention is: the vacuum heat collection tube 3 is composed of two layers of glass, and the middle is evacuated. This design effectively reduces the loss of heat to the surrounding environment and improves the heat collection efficiency. The outer surface of the inner glass tube is usually coated with a layer of special material coating, which can efficiently absorb solar radiation energy and convert it into thermal energy. When sunlight shines on the vacuum heat collection tube 3, the coating absorbs the heat of solar radiation, causing the water temperature in the inner glass tube to rise. Since the specific gravity of cold water is greater than that of hot water, and the hot water rises and the cold water sinks, the water in the vacuum heat collection tube 3 will produce a natural convection cycle, so that the water temperature of the entire system gradually increases, realizing the effective use of solar energy.

[0038] The initial position of the photovoltaic panel 43 is shown in FIG. Figure 5 At this time, the photovoltaic panel 43 is located below the vacuum heat collecting tube 3, so that the vacuum heat collecting tube 3 is not blocked and fully receives light, and the heat collecting position of the photovoltaic panel 43 is as shown in FIG. Figure 6The photovoltaic panel 43 is located above the vacuum collector tube 3, so that the energy absorbing side of the photovoltaic panel 43 faces upward to fully receive light, and under the swinging and stretching of the first side photovoltaic panel 432 and the second side photovoltaic panel 434, the angle between the light and the first side photovoltaic panel 432 and the angle between the light and the second side photovoltaic panel 434 are increased, thereby improving the efficiency of the photovoltaic panel 43 absorbing solar energy.

[0039] Exemplarily, when the photovoltaic panel 43 is located at the initial position, the main photovoltaic panel 433, the first side photovoltaic panel 432, and the second side photovoltaic panel 434 form a concave structure on the side facing the vacuum heat collecting tube 3, so that when the photovoltaic panel 43 is located at the initial position, the sunlight is reflected by the photovoltaic panel 43 with the concave structure, so that the back side of the vacuum heat collecting tube 3 can also absorb solar energy, thereby improving the heat collection efficiency of the vacuum heat collecting tube 3. Exemplarily, the main photovoltaic panel 433, the first side photovoltaic panel 432, and the second side photovoltaic panel 434 are arranged in a mirror structure on the side facing the vacuum heat collecting tube 3 to improve the reflection effect of sunlight.

[0040] For example, Figure 5 As shown, the main photovoltaic panel 433 , the first side photovoltaic panel 432 and the second side photovoltaic panel 434 are arc-shaped structures respectively, and the inner concave surface of the arc-shaped structure is arranged toward one side of the vacuum heat collecting tube 3 .

[0041] For example, Fig.10 As shown, the main photovoltaic panel 433, the first side photovoltaic panel 432 and the second side photovoltaic panel 434 are respectively planar structures. When the photovoltaic panel 43 is located at the initial position, the main photovoltaic panel 433 has an angle with the first side photovoltaic panel 432 and the second side photovoltaic panel 434 respectively.

[0042] For example, see Figure 4 and Figure 8The extension assembly 44 includes a first gear 4322, a first tooth block 441, a second gear 4342, a second tooth block 442 and a mounting plate 443. The mounting plate 443 is fixedly arranged on the outside of the water tank 1. The vacuum heat collecting tube 3 passes through the mounting plate 443. A guide rail 4431 is provided on the mounting plate 443. The guide rail 4431 is located on the circumferential outer side of the vacuum heat collecting tube 3. The first side photovoltaic panel 432 is rotatably connected to the main photovoltaic panel 433 through the first rotating shaft 4321. The second side photovoltaic panel 434 is rotatably connected to the main photovoltaic panel 433 through the second rotating shaft 4341. The outer end of the first rotating shaft 4321 and the outer end of the second rotating shaft 4341 are respectively slidably connected to the mounting plate 443 through the guide rail 4431, wherein the first rotating shaft 4321 is fixedly connected with the first gear 4322, the second rotating shaft 4341 is fixedly connected with the second gear 4342, and the mounting plate 443 is respectively fixedly connected with the first tooth block 441 and the second tooth block 442, the first tooth block 441 is located on the side of the guide rail 4431 away from the vacuum heat collecting tube 3, and the second tooth block 442 is located on the side of the guide rail 4431 close to the vacuum heat collecting tube 3, and the photovoltaic panel 43 is connected to the photovoltaic panel 43 along the guide rail 4431. Figure 8 When the position shown rotates counterclockwise, the outer end of the first rotating shaft 4321 and the outer end of the second rotating shaft 4341 slide along the guide rail 4431 respectively. When the photovoltaic panel 43 is located at the heat collection position, the first gear 4322 is meshed with the first tooth block 441 for transmission, and the second gear 4342 is meshed with the second tooth block 442 for transmission, so that the first side photovoltaic panel 432 is driven to swing clockwise under the rotation of the first gear 4322, and the second side photovoltaic panel 434 is driven to swing counterclockwise under the rotation of the second gear 4342, so as to realize the extension of the photovoltaic panel 43. Figure 8 The middle dotted line indicates the photovoltaic panel 43 located at the heat collection position.

[0043] It should be noted that in order to prevent the second gear 4342 from being interfered with by the first gear block 441 when the photovoltaic panel 43 rotates counterclockwise, the radius of the second gear 4342 is smaller than the radius of the first gear 4322 .

[0044] In one embodiment, continue to refer to Figure 2 , Figures 5 to 9 The photovoltaic panel supporting device for photovoltaic energy storage also includes a supporting component 45, and the supporting component 45 includes a first sealing strip 452. The first sealing strip 452 is arranged between adjacent vacuum collector tubes 3. When the photovoltaic panel 43 is located at the heat collection position, the second side photovoltaic panel 434 and the first side photovoltaic panel 432 arranged adjacent to the first sealing strip 452 are respectively frictionally abutted against the first sealing strip 452.

[0045] In the above embodiment, due to rainy days, rainwater directly drips on the surface of the vacuum collector tube 3, so that after the rain stops, water stains are formed on the outer surface of the glass of the vacuum collector tube 3. The water stains are obvious and accumulate for a long time, which will reduce the light transmittance of the surface of the vacuum collector tube 3. The existence of water stains causes uneven patches to form on the surface of the vacuum collector tube 3, causing part of the solar radiation to be reflected by the water stains, thereby reducing the efficiency of the vacuum collector tube 3 in absorbing solar energy; therefore, the first sealing strip 452 is squeezed and clamped by the first side photovoltaic panel 432 and the second side photovoltaic panel 434, On rainy days, the photovoltaic panel 43 is located at the heat collection position to shield the vacuum heat collecting tube 3 from rain and prevent rain from directly dripping onto the surface of the vacuum heat collecting tube 3. The first sealing strip 452 is used to seal the gap between the first side photovoltaic panel 432 and the second side photovoltaic panel 434, so that the rain dripping from the upper surface of the photovoltaic panel 43 slides down to the ground under the action of gravity, avoiding the rain dripping from the upper surface of the photovoltaic panel 43 from gathering and dripping onto the ground between adjacent vacuum heat collecting tubes 3, causing splashing of rainwater and reducing the rain shielding effect of the vacuum heat collecting tube 3.

[0046] In one embodiment, continue to refer to Figure 2 , Figures 5 to 9 The first sealing strip 452 is connected to an extrusion coating driving member, which is arranged on the base 2 and is located at the lower side of the first sealing strip 452. When the photovoltaic panel 43 is located at the heat collection position, the first sealing strip 452 is driven by the extrusion coating driving member to move to the coating position in the direction close to the first side photovoltaic panel 432 and the second side photovoltaic panel 434. Thus, while the first side photovoltaic panel 432 and the second side photovoltaic panel 434 seal the first sealing strip 452 in the lateral extrusion and resistance, the first sealing strip 452 moves upward to respectively extrude and resist the outer ends of the first side photovoltaic panel 432 and the outer ends of the second side photovoltaic panel 434, thereby fully covering and sealing the outer ends of the first side photovoltaic panel 432 and the outer ends of the second side photovoltaic panel 434, and ensuring the sealing and rainproof effect between the adjacent first side photovoltaic panel 432 and the second side photovoltaic panel 434.

[0047] For example, see Figures 4 to 9The extruded coated driving member includes a connecting plate 431, an end plate 435, a wedge 451, a convex block 453 and a spring 456. The end of the main photovoltaic panel 433 away from the water tank 1 is fixedly connected to the connecting plate 431, and the main photovoltaic panel 433 is transmission-connected to the circumferential displacement assembly through the connecting plate 431. The end of the main photovoltaic panel 433 close to the water tank 1 is fixedly connected to the end plate 435. The circumferential side of the end plate 435 and the circumferential side of the connecting plate 431 are respectively fixedly connected to the wedge 451, and the wedge 451 and the convex block are fixedly connected. The block 453 is frictionally engaged, the protrusion 453 is fixedly connected to one end of the guide rod 454, a bearing plate 455 is fixedly connected to the base 2, the other end of the guide rod 454 passes through the bearing plate 455 and is fixedly connected to the first sealing strip 452, the side of the guide rod 454 located between the first sealing strip 452 and the bearing plate 455 is sleeved with a spring 456, the lower end of the first sealing strip 452 is fixedly connected to a limiting rod 457, the limiting rod 457 passes through the bearing plate 455 and is slidably connected to the bearing plate 455.

[0048] In the above embodiment, when the photovoltaic panel 43 rotates from the initial position to the heat collection position, the first sealing strip 452 is moved upward by the wedge blocks 451 on the connecting plate 431 and the end plate 435 pressing and abutting against the protrusions 453 .

[0049] It should be noted that the extension direction of the first sealing strip 452 is consistent with the extension direction of the vacuum heat collecting tube 3 , and the upward movement direction of the first sealing strip 452 refers to the upward movement of the first sealing strip 452 along the radial direction of the vacuum heat collecting tube 3 .

[0050] Exemplarily, a second sealing strip 48 is fixedly provided on the side of the main photovoltaic panel 433 adjacent to the first side photovoltaic panel 432, and a second sealing strip 48 is fixedly provided on the side of the main photovoltaic panel 433 adjacent to the second side photovoltaic panel 434, thereby respectively performing waterproof treatment on the rotating connection gap between the first side photovoltaic panel 432 and the main photovoltaic panel 433 and the rotating connection gap between the second side photovoltaic panel 434 and the main photovoltaic panel 433, thereby fully ensuring the rainproof effect of the vacuum collector tube 3.

[0051] For example, Figures 1 to 3 As shown, the end of the vacuum heat collecting tube 3 away from the water tank 1 is overlapped on the limit seat 21, and the limit seat 21 is fixedly connected to the base 2 to provide auxiliary support for the end of the vacuum heat collecting tube 3 away from the water tank 1;

[0052] The circumferential displacement assembly includes a motor 41, a toothed chain 42, a driving gear 46 and a driven gear 47. The motor 41 is placed on the base 2. The output shaft of the motor 41 is fixedly connected with a driving gear 46. The driving gear 46 is meshed with a toothed chain 42. The toothed chain 42 is meshed with a driven gear 47. The driven gear 47 is rotatably connected to a bearing seat 471. The side end of the bearing seat 471 is fixedly connected to a limit seat 21. The bearing seat 471 is sleeved on the outside of the vacuum heat collecting tube 3 and is spaced from the vacuum heat collecting tube 3. The side of the driven gear 47 away from the limit seat 21 is fixedly connected with a connecting plate 431. After the water in the water tank 1 is heated to the target temperature, the motor 41 is started, thereby realizing the rotation of multiple photovoltaic panels 43.

[0053] It should be noted that when the photovoltaic panel carrying device for photovoltaic energy storage is used in clear weather, the photovoltaic panel 43 is located at the initial position, the vacuum heat collecting tube 3 is completely exposed to the sun, and receives the sunlight. When the vacuum heat collecting tube 3 absorbs enough solar energy to heat the water in the water tank 1 to the target temperature, the motor 41 is started, and the photovoltaic panel 43 is rotated from the initial position to the heat collecting position under the transmission of the driving gear 46, the toothed chain 42 and the driven gear 47, so that the heat absorbing end of the photovoltaic panel 43 is exposed to the sun, so as to realize the continued collection and utilization of solar energy for subsequent solar radiation in the area where the same device is arranged, without occupying additional space for photovoltaic storage of electric energy;

[0054] Moreover, the photovoltaic panel 43 includes a first side photovoltaic panel 432, a main photovoltaic panel 433 and a second side photovoltaic panel 434. The first gear 4322 and the first tooth block 441, and the second gear 4342 and the second tooth block 442 are meshed and driven to realize that the first side photovoltaic panel 432 and the second side photovoltaic panel 434 are stretched outward, and the angle between the light and the first side photovoltaic panel 432 and the angle between the light and the second side photovoltaic panel 434 are increased, thereby improving the efficiency of the solar energy absorbed by the photovoltaic panel 43;

[0055] In addition, on rainy days, the device of the present invention can also start the motor 41 to place the photovoltaic panel 43 in the heat collection position, that is, the photovoltaic panel 43 is located above the vacuum heat collection tube 3. At this time, the photovoltaic panel 43 protects the vacuum heat collection tube 3 from rain, and when the photovoltaic panel 43 rotates, the adjacent first side photovoltaic panel 432 and the second side photovoltaic panel 434 squeeze the first sealing strip 452 sideways. At the same time, the friction between the wedge block 451 and the protrusion 453 is used to realize the upward movement of the first sealing strip 452 to the first side photovoltaic panel 432. The outer end of the second side photovoltaic panel 434 is wrapped in contact with the outer end, which fully ensures the sealing of the gap between the adjacent first side photovoltaic panel 432 and the second side photovoltaic panel 434, so that rainwater dripping on the photovoltaic panel 43 slides to the ground on one side, thereby improving the waterproof effect of the vacuum collector tube 3 and preventing rainwater from dripping directly on the outer glass surface of the vacuum collector tube 3, causing water stains to form on the outer glass surface of the vacuum collector tube 3, resulting in part of the solar radiation being reflected by the water stains, thereby affecting the efficiency of the vacuum collector tube 3 in absorbing solar energy.

[0056] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention.
