[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] The present utility model provides as Figures 1-5A composite photovoltaic-thermal PVT integrated device with energy storage heat pump as shown in the figure includes a device support 1. Inside the upper end of the device support 1, there is a fixed and inclined battery support 2. At the upper end of the battery support 2, there is a storage battery 3. At the upper end of the device support 1, there is a fixed and inclined support frame 4, and the support frame 4 is located above the battery support 2 and is parallel to the battery support 2. Inside the upper end of the support frame 4, a photovoltaic panel 5 is clamped, and the photovoltaic panel 5 is connected to the storage battery 3 through a wire harness. Below the photovoltaic panel 5, there is a heat absorption plate 6, and the heat absorption plate 6 is clamped inside the support frame 4. Below the heat absorption plate 6, there is a heat storage pipe rack 7, and the inside of the heat storage pipe rack 7 is hollow. At the lower left side and the upper right side of the heat storage pipe rack 7, there are connected water guide pipes 8 respectively, and the two water guide pipes 8 are respectively connected to the water inlet pipe and the water outlet pipe. The composite photovoltaic-thermal PVT integrated device with energy storage heat pump converts light energy into electrical energy through the photovoltaic panel 5 and stores the electrical energy in the storage battery 3 through the wire harness. At the same time, it can convert solar energy into heat energy through the heat storage pipe rack 7 and store the heat energy in the water inside the heat storage pipe rack 7. And the water inside the heat storage pipe rack 7 can be input and output through the two water guide pipes 8, which is more convenient to export and use the water storing heat energy.

[0028] Preferably, a heat insulation layer 9 is arranged at the lower end of the heat storage pipe rack 7. Inside the heat storage pipe rack 7, there are connected multiple heat storage pipes 10, and the multiple heat storage pipes 10 are all located above the heat insulation layer 9. So that the heat storage pipe rack 7 can convert solar energy into heat energy through the multiple heat storage pipes 10 and store the heat energy in the water inside the heat storage pipe rack 7 and the heat storage pipes 10, thereby improving the utilization efficiency of solar energy. At the same time, the heat storage pipe rack 7 and the multiple heat storage pipes 10 can be insulated through the heat insulation layer 9 at the lower end to prevent heat loss.

[0029] Preferably, a temperature-sensitive resistor 11 penetrates downward inside the left side of the lower end of the heat storage pipe 10, and the lower end of the temperature-sensitive resistor 11 protrudes outside the lower end of the heat storage pipe 10. Inside the upper end of the heat insulation layer 9, there are opened multiple limit card slots 12. The lower ends of the multiple heat storage pipes 10 are all sleeved with heating pads 13, and the multiple heating pads 13 are respectively located inside the multiple limit card slots 12. The right side of the lower end of the heating pad 13 is connected to the storage battery 3 through a wire harness, and the left end of the heating pad 13 is connected to the right end of the temperature-sensitive resistor 11 through a wire harness. The lower end of the temperature-sensitive resistor 11 is connected to the storage battery 3 through a wire harness. During the process of the multiple heat storage pipes 10 absorbing and converting solar energy, the water temperature inside the heat storage pipes 10 can be detected through the temperature-sensitive resistor 11. Since the temperature-sensitive resistor 11 is connected in series with the storage battery 3 and the heating pad 13 through a wire harness and can change the internal resistance value according to the change of temperature, and the higher the temperature, the larger the internal resistance value of the temperature-sensitive resistor 11. Therefore, the lower the water temperature inside the heat storage pipes 10, the larger the current flowing through the heating pad 13, and the higher the temperature generated by the heating pad 13. On the contrary, the lower the temperature generated by the heating pad 13, ensuring that the water temperature inside the heat storage pipes 10 remains stable.

[0030] Preferably, the storage battery 3 can convert the stored electrical energy into the thermal energy of the water inside the heat storage pipe 10 through the heating pad 13, and can perform adaptive control according to the resistance value of the temperature-sensitive resistor 11 with the change of water temperature, so that the light energy can be converted into both electrical energy and thermal energy, and the electrical energy can be converted into thermal energy again, ensuring the stable energy conversion of the combined photovoltaic-thermal PVT and energy storage heat pump integrated device.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
