Embodiment 1

[0022] As shown in the accompanying drawings, Figures 1 to 4The illustrated split solar photovoltaic heat pump structure includes a support 1, which is in the form of a vertical rod, is made of metal material, and provides stable support for the photovoltaic panel 3 and other components as the main load-bearing structure, while reducing the occupation of the greenhouse planting area. The outer wall of the support 1 is provided with a connecting frame 2, which is generally made of metal material and connected to the support 1 by welding, screwing or other methods. The connecting frame 2 is arranged on one side of the outer wall of the support 1 and is used to fix the photovoltaic panel 3, thereby firmly connecting the photovoltaic panel 3 to the support 1 and ensuring the stability and safety of the photovoltaic panel 3. The connecting frame 2 is provided with photovoltaic panels 3 on both sides. The photovoltaic panel 3 is formed by cutting, assembling and packaging silicon material, and converts solar energy into electrical energy to provide power for the heat pump mechanism 8 and other electrical appliances.

[0023] The photovoltaic panel 3 is provided with a cleaning mechanism 4 on one side, which is composed of a fixed plate 11, a sliding rail 12 and a cleaning roller 13.

[0024] The heat pump mechanism 8 is provided with three triangular supports 9 below. The three triangular supports 9 are arranged uniformly along the circumferential direction of the support 1. The triangular supports 9 are usually made of metal pipes or profiles and are processed by cutting and welding to provide additional support and stability to the entire structure and ensure the structural safety under natural conditions such as wind.

Embodiment 2

[0025] Based on the embodiment 1, the scheme in embodiment 1 is further refined and introduced in combination with the specific working mode as follows. Figures 1 to 4As shown, see the following description for details:

[0026] As a preferred embodiment, the cleaning mechanism 4 includes a fixed plate 11, a slide rail 12 and a cleaning roller 13. Fixed plates 11 are provided on both sides of the photovoltaic panel 3, and a slide rail 12 is provided on one side of the outer wall of the fixed plate 11. A cleaning roller 13 is provided on one side of the slide rail 12, so that the cleaning roller 13 can be displaced along the horizontal direction of the photovoltaic panel 3 through the slide rail 12. Furthermore, the fixed plate 11 is usually made of metal or high-strength plastic to ensure that it has sufficient strength and durability, thereby providing a stable installation foundation for the slide rail 12 and achieving effective cleaning. The slide rail 12 provides a guide rail for the cleaning roller 13, so that it can move smoothly along the horizontal direction of the photovoltaic panel 3 to achieve the cleaning purpose. The cleaning roller 13 is made of soft material and is usually equipped with a metal shaft core in the center. The material is combined with the shaft core by bonding, mechanical fixation, etc., and plays a role in removing dust, dirt and other impurities by moving on the surface of the photovoltaic panel 3, keeping the photovoltaic panel 3 clean and efficiently converting energy.

[0027] As a preferred embodiment, a support arm 14 is provided under the load-bearing platform 5, and the support arm 14 is obliquely arranged on the outer wall of the bracket 1, and there are three groups of support arms 14, and the three groups of support arms 14 are evenly arranged along the circumferential direction of the bracket 1. Furthermore, the support arm 14 is usually made of metal pipes or profiles, and is processed through cutting, bending, welding and other processes to ensure that it has stable supporting force, providing additional support from the bracket 1 to the load-bearing platform 5, and enhancing the stability of the entire structure, especially the vibration and pressure generated when the equipment is running on the load-bearing platform 5.

[0028] As a preferred embodiment, the heat pump mechanism 8 includes a condenser 15, an evaporator 16 and a fan 17. The top of the condenser 15 is connected to the compressor 6 through a pipeline. The evaporator 16 is provided on one side of the condenser 15, and the fan 17 is provided below the evaporator 16. There are two groups of fans 17, and the two groups of fans 17 are evenly arranged along the horizontal direction of the evaporator 16. A connection port 18 is provided on one side of the outer wall of the fan 17. Furthermore, the condenser 15 is composed of metal tubes and fins. In heating mode, the condenser 15 serves as a heat dissipation component of the heat pump mechanism 8, releasing heat to heat the air in the greenhouse; in cooling mode, it serves as a heat absorption component to help cool the air in the greenhouse. The fan 17 generates an airflow through the rotation of the impeller, which promotes the air to flow through the evaporator 16, enhances the heat exchange effect, and thus improves the cooling or heating efficiency of the heat pump system. At the same time, the heat released by the heat pump mechanism 8 is sent into the greenhouse air duct through the fan 17 to provide the required heat for the greenhouse.

[0029] As a preferred embodiment, the outer wall side of the battery 7 is provided with a power grid interface 19, and the battery 7 can be connected with the circuit through the power grid interface 19. Further, the power grid interface 19 allows the battery 7 to exchange electric energy with the external power grid, that is, the excess electric energy can be delivered to the power grid, and the electric energy can also be absorbed from the power grid to meet the operation demand of the heat pump system.

[0030] As a preferred embodiment, the bottom plate 10 is provided with a fixing bolt 20 at each of the four corners of the bottom, and further, the fixing bolt 20 is usually made of metal and is manufactured by mechanical processing such as turning, drilling and the like. It is inserted into the ground and fixed to maintain the stability of the entire solar photovoltaic heat pump structure and prevent movement or dumping due to environmental influences.

[0031] The working process of the utility model is as follows: firstly, the photovoltaic panel 3 captures solar energy and converts it into electric energy, and this part of electric energy is delivered to the battery 7 for storage. When the greenhouse needs to be heated, the compressor 6 starts to drive the heat pump mechanism 8 to work. The refrigerant becomes high-temperature and high-pressure gas under the action of the compressor 6 and flows to the condenser 15. In the condenser 15, the high-temperature refrigerant releases heat to the passing air or water, thereby transferring heat to the greenhouse and improving the internal temperature. At the same time, the fan 17 starts to push the air to flow through the condenser 15, helping the heat to be more evenly distributed in the greenhouse. The above is the working principle of the split type solar photovoltaic heat pump structure.
