[0003] However, during use, the single-cylinder household photovoltaic electric heating integrated machine disclosed in the above patent has a problem: the transparent cover on the shell does not have a heat preservation effect in order to ensure light transmittance. After the sun sets, the heat inside the shell can easily be lost to the outside through the transparent cover, which reduces the heat preservation effect of the shell on the photovoltaic electric heating cylinder. Therefore, it is necessary to propose a single-cylinder household photovoltaic electric heating integrated machine to solve the above problems. Utility Model Content

After the sun sets, the heat inside the shell can easily be lost to the outside through the transparent cover, which reduces the heat preservation effect of the shell on the photovoltaic electric heating cylinder.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a single-cylinder household photovoltaic electric heating integrated machine, comprising a base plate and a photovoltaic electric heating cylinder, with support plates fixedly installed at both ends of the top of the base plate, and rotating shafts fixedly installed at both ends of the photovoltaic electric heating cylinder, the rotating shafts being rotatably connected to the support plates via an adjustment component, a shell covering the outside of the photovoltaic electric heating cylinder, the rotating shafts penetrating the side of the shell and being fixedly connected to the shell, the inner wall of the shell and the outer wall of the photovoltaic electric heating cylinder forming a sealed space, a first heat insulation layer being provided on the inner wall of the shell, a transparent cover plate being fixedly installed on the side of the shell, and auxiliary components being provided at the outer ring of the shell;

[0006] The auxiliary component includes two arc-shaped guide rails, which are respectively fixedly installed at both ends of the housing. Limiting grooves are fixedly opened inside the arc-shaped guide rails. A movable cover is slidably installed between the two limiting grooves. A rubber frame is fixedly installed on the side of the movable cover near the housing, and a second heat insulation layer is fixedly installed on the side of the movable cover near the housing.

[0007] Preferably, the side of the rubber frame away from the movable cover is movably fitted to the outer wall of the housing.

[0008] Preferably, a handle is fixedly provided on the side of the movable cover.

[0009] Preferably, a thin-film solar cell is provided on the outer wall of the photovoltaic thermal cylinder, and a junction box is provided on the thin-film solar cell. A water inlet pipe and a water outlet pipe are fixedly provided at both ends of the photovoltaic thermal cylinder, and the water inlet pipe and the water outlet pipe both penetrate through the end of the shell.

A first limiting hole is fixedly disposed inside the rotating disk, and a plurality of second limiting holes are fixedly disposed inside the support plate in a ring-shaped and uniformly distributed manner.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. With the installation of auxiliary components, after sunset, pull the handle to move the movable cover between the two limit grooves until the movable cover slides to the end of the arc-shaped guide rail. At this time, the movable cover and the transparent cover are facing each other, thus forming a closed space between the transparent cover, the movable cover and the rubber frame. This prevents the heat inside the shell from escaping through the transparent cover, solving the problem that in the existing single-cylinder household photovoltaic electric heating integrated machine, the transparent cover on the shell does not have a heat preservation effect in order to ensure light transmittance.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides, for example Figures 1-5 The single-cylinder household photovoltaic electric heating integrated machine shown includes a base plate 1 and a photovoltaic electric heating cylinder 3. Support plates 2 are fixedly installed at both ends of the top of the base plate 1. Rotating shafts 6 are fixedly installed at both ends of the photovoltaic electric heating cylinder 3. The rotating shafts 6 are rotatably connected to the support plates 2 through bearings. The photovoltaic electric heating cylinder 3 is covered by a shell 10. The rotating shafts 6 pass through the side of the shell 10 and are fixedly connected to the shell 10. The central axes of the photovoltaic electric heating cylinder 3, the rotating shafts 6, and the shell 10 are on the same horizontal line. A transparent cover plate 11 is fixedly installed on the side of the shell 10. A water inlet pipe and a water outlet pipe are fixedly installed at both ends of the photovoltaic electric heating cylinder 3, respectively. Both the water inlet pipe and the water outlet pipe pass through the end of the shell 10. In use, water is injected into the photovoltaic electric heating cylinder 3 through the water inlet pipe. Sunlight shines on the photovoltaic electric heating cylinder 3 through the transparent cover plate 11 to heat the water. When needed, the water is discharged through the water outlet pipe.

[0025] Since the inner wall of the shell 10 and the outer wall of the photovoltaic thermal cylinder 3 form a sealed space, and the inner wall of the shell 10 is provided with a first heat insulation layer, the shell 10 forms a heat insulation box to keep the heat of the photovoltaic thermal cylinder 3 warm. Considering that in the existing single-cylinder household photovoltaic electric heating integrated machine, the transparent cover plate 11 on the shell 10 does not have a heat insulation effect in order to ensure light transmittance, and the heat inside the shell 10 is easily lost to the outside through the transparent cover plate 11 after the sun sets, reducing the heat insulation effect of the shell 10 on the photovoltaic thermal cylinder 3, this utility model provides an auxiliary component at the outer ring of the shell 10. By setting the auxiliary component, the problem of the transparent cover plate 11 not having a heat insulation effect is compensated, and the photovoltaic thermal cylinder 3 is better insulated.

[0026] Specifically, the auxiliary components include two arc-shaped guide rails 12, which are fixedly installed at both ends of the housing 10. Limiting grooves 13 are fixedly opened inside the arc-shaped guide rails 12. A movable cover 14 is slidably installed between the two limiting grooves 13. A rubber frame 15 is fixedly installed on the side of the movable cover 14 near the housing 10. A second heat insulation layer is fixedly installed on the side of the movable cover 14 near the housing 10.

[0027] After sunset, the handle 17 is fixedly installed on the side of the movable cover 14. Pulling the handle 17 causes the movable cover 14 to slide between the two limiting grooves 13 until the movable cover 14 slides to the end of the arc-shaped guide rail 12. At this time, the movable cover 14 and the transparent cover 11 are facing each other. In addition, the side of the rubber frame 15 away from the movable cover 14 is in contact with the outer wall of the shell 10, thus forming a closed space between the transparent cover 11, the movable cover 14 and the rubber frame 15. This prevents the heat inside the shell 10 from escaping through the transparent cover 11. This solves the problem that in the existing single-cylinder household photovoltaic electric heating integrated machine, the transparent cover 11 on the shell 10 does not have a heat preservation effect in order to ensure light transmittance. After sunset, the heat inside the shell 10 is easily lost to the outside through the transparent cover 11, which reduces the heat preservation effect of the shell 10 on the photovoltaic electric heating cylinder 3.

[0028] Meanwhile, a screw 16 is threadedly connected to the side wall of the arc-shaped guide rail 12. The threaded end of the screw 16 extends into the interior of the limiting groove 13. After the movable cover 14 and the transparent cover 11 are facing each other, the two screws 16 are rotated to press the movable cover 14 into the interior of the limiting groove 13, thereby pressing the rubber frame 15 onto the housing 10, improving the sealing between the rubber frame 15 and the housing 10, and providing better heat insulation for the transparent cover 11.

[0029] Furthermore, a thin-film solar cell 4 is provided on the outer wall of the photovoltaic thermal cylinder 3, and a junction box 5 is provided on the thin-film solar cell 4. When sunlight with a spectrum of 0.32 to 2.5 μm is projected onto the thin-film solar cell 4, most of it is absorbed, a small amount of solar energy is converted into electrical energy, and most of it is converted into heat energy, thereby realizing the integrated photovoltaic-electric-thermal effect. For the specific working principle, please refer to the literature cited in the background technology, and this application will not elaborate further.

[0030] Since the rising position of the sun changes with the seasons, in order to improve the collection and utilization rate of solar energy without increasing the area of ​​the transparent cover plate 11, the rotating shaft 6 in this utility model is rotatably connected to the support plate 2 through an adjusting component. The adjusting component includes a rotating disk 7, which is fixedly installed at one end of the rotating shaft 6 that movably passes through the side wall of the support plate 2. A first limiting hole is fixedly installed inside the rotating disk 7, and several second limiting holes are fixedly installed inside the support plate 2 in a ring-shaped and uniformly distributed manner. A movable rod 8 is slidably connected between the first limiting hole and the second limiting hole. A handle is fixedly installed at the end of the movable rod 8. A spring 9 is fixedly connected between the handle and the side of the rotating disk 7 away from the support plate 2. The spring 9 is movably sleeved on the outer ring of the movable rod 8.

[0031] Specifically, when it is necessary to adjust the sun-facing direction of the transparent cover 11, pull the handle to pull the movable rod 8 out from the second limiting hole, thereby removing the restriction on the position of the rotating disk 7. At this time, the movable rod 8 can be rotated to rotate the rotating disk 7, the rotating shaft 6, the photovoltaic thermal cylinder 3, the shell 10, and the transparent cover 11, thereby adjusting the sun-facing direction of the transparent cover 11 to match the position of the sun, which facilitates the improvement of the solar energy collection and utilization rate, better heating of the photovoltaic thermal cylinder 3, and improving the practicality of the device. After the transparent cover 11 is rotated to the appropriate position, the movable rod 8 is inserted into the corresponding second limiting hole to limit and fix the rotating disk 7, thereby fixing the position of the transparent cover 11.

[0032] Working Principle: During use, water is injected into the photovoltaic thermal cylinder 3 through the inlet pipe. Sunlight shines on the photovoltaic thermal cylinder 3 through the transparent cover 11, heating the water. When needed, the water is discharged through the outlet pipe. Since the inner wall of the shell 10 and the outer wall of the photovoltaic thermal cylinder 3 form a sealed space, and the inner wall of the shell 10 is provided with a first insulation layer, the shell 10 forms an insulated box to retain the heat from the photovoltaic thermal cylinder 3. After sunset, pulling the handle 17 causes the movable cover 14 to slide between the two limiting grooves 13 until it reaches the end of the arc-shaped guide rail 12. At this point, the movable cover 14 and the transparent cover 11 are facing each other. Additionally, the side of the rubber frame 15 away from the movable cover 14 is in contact with the outer wall of the shell 10, thus forming a closed space between the transparent cover 11, the movable cover 14, and the rubber frame 15, preventing heat from the inside of the shell 10 from dissipating through the transparent cover 11. After the movable cover 14 and the transparent cover 11 are aligned, rotate the two screws 16 to press the movable cover 14 into the inside of the limiting groove 13, thereby pressing the rubber frame 15 onto the housing 10, improving the sealing between the rubber frame 15 and the housing 10, and providing better heat insulation for the transparent cover 11. When it is necessary to adjust the sun-facing direction of the transparent cover 11, pull the handle to pull the movable rod 8 out from the inside of the second limiting hole, thereby removing the limitation on the position of the rotating disk 7. At this time, the movable rod 8 can be rotated to drive the rotating disk 7, the rotating shaft 6, the photovoltaic thermal cylinder 3, the housing 10, and the transparent cover 11 to rotate, thereby adjusting the sun-facing direction of the transparent cover 11 to match the position of the sun, which is conducive to improving the collection and utilization rate of solar energy and better heating the photovoltaic thermal cylinder 3. After the transparent cover 11 is rotated to the appropriate position, insert the movable rod 8 into the corresponding second limiting hole to limit and fix the rotating disk 7, thereby fixing the position of the transparent cover 11.
