[0002] At present, most of the heating methods in rural areas in northern my country use coal or electric boilers to heat the heating medium. This method has problems such as waste of resources, high cost, waste of human resources, and environmental pollution.

[0003] The Chinese patent with the patent number of 201911426852.6 discloses a cellular high-efficiency solar thermal collection and storage intelligent central control system, which uses a large-capacity water tank for heat storage. The heat storage medium is water or thermal oil, and the heat storage container is a large-capacity water tank. There is a problem of large floor space, and it also involves the treatment of water tank insulation. The operation and maintenance costs are high, and it is not easy to promote and apply. The Chinese patent with the patent number of 202211296436.0 discloses a solar ground source heat pump joint operation system and method. It is a solar energy and ground source heat pump joint operation system that utilizes solar energy and geothermal energy, in which the solar energy utilization part uses a hot water storage tank, which is an application of solar thermal energy. This technical solution has the problem of high cost of hot water storage tanks and high operation and maintenance costs.

[0004] The current heating systems in the above rural areas all use heat storage medium heat dissipation for heating, and all have problems such as high heating system cost, high heating operation cost, difficult maintenance of heating equipment, and large area occupied. Summary of the invention

[0005] The purpose of the present invention is to solve the deficiencies in the above-mentioned background technology and to provide a rural distributed residential solar heat storage heating system, which has the characteristics of low heating system cost, low heating operation cost, easy maintenance of heating equipment, saving ground space, energy saving and environmental protection.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions: The rural distributed residential solar thermal storage heating system has the following structure: the photovoltaic panel is connected to the inverter, the inverter is connected to the air blower, the air compressor and the collector through wires, the focusing device is installed above the collector, the air blower is connected to the air inlet of the collector, the air outlet of the collector is connected to the indoor heat release device and the air compressor through pipelines, the air outlet of the air compressor is connected to the underground heat storage system through pipelines, and the air outlet of the underground heat storage system is connected to the indoor heat release device through pipelines.

[0007] Preferably, the above-mentioned focusing device is installed in a courtyard.

[0008] Preferably, the photovoltaic panel is installed on the roof of a house.

[0009] Preferably, a first control valve is provided on the direct heating pipe between the indoor heat release device and the collector.

[0010] Preferably, there is a second control valve on the pipeline between the underground heat storage system and the indoor heat release device.

[0011] Preferably, the underground heat storage system is composed of a plurality of air storage devices connected in series, in parallel, or in series and parallel, connected by pipelines.

[0012] Preferably, the air storage device is a hard plastic air storage tank or a soft plastic air storage bag.

[0014] The heat storage and heating medium of the heating system of the present invention is air, and the energy storage form is compressed air energy storage and heat storage. The underground is used as the storage location of the heat storage device to save ground space. The heat storage container air storage device adopts an air tank or an air storage bag to greatly reduce the cost and facilitate maintenance and replacement. In addition, the air storage device is set underground, and the underground temperature is stable, which can reduce the insulation cost of the air storage device. At the same time, the system uses both the photovoltaic effect and the photothermal effect of solar energy, and uses the energy of photovoltaic power generation to realize system control and auxiliary heating, which can also reduce the cost of system operation.

[0015] Taking into account that rural areas are mainly distributed residential areas and the residential space is relatively large, and the resource endowment of rural areas, namely, abundant renewable energy resources such as solar energy, the present invention makes full use of solar energy resources, utilizes the solar photovoltaic effect as the power supply source of the system, and utilizes the solar thermal effect as the heating source of the system, which can achieve clean heating in rural areas in winter, and can gradually adjust and change the status quo of traditional combustion heating. On the basis of ensuring the safety, practicality and comfort of winter heating in rural houses, it takes into account economy and cleanliness, thereby realizing high-quality development of heating in rural areas. The present invention has the characteristics of energy saving and environmental protection. BRIEF DESCRIPTION OF THE DRAWINGS

The air compressor 5 is connected, and a first control valve 11 is arranged on the direct heating pipe 2 between the indoor heat release device 8 and the collector 10. The air outlet of the air compressor 5 is connected to the underground heat storage system 7 through a pipeline. The underground heat storage system 7 is composed of a plurality of air storage devices 6 connected in series, in parallel or in series and in parallel, which are connected by pipelines. The air storage device 6 adopts a hard plastic air storage tank or a soft plastic air storage bag. The underground heat storage system 7 is arranged under the ground 9. The air outlet of the underground heat storage system 7 is connected to the indoor heat release device 8 through a pipeline. There is a second control valve 12 on the pipeline between the underground heat storage system 7 and the indoor heat release device 8.

[0020] The above-mentioned focusing device 3 can select a variety of focusing devices such as Fresnel lenses to achieve the focusing of solar energy. The indoor heat release device 8 can select a device such as a multi-leaf exhaust vent that can release hot air into the room, so as to achieve indoor heating. The light-receiving surface of the collector 10 is coated with ordinary black paint or lead sulfide, metal oxide paint, etc. according to the cost. The non-light-receiving surface of the collector can be provided with an insulation layer. The size of the collector is set according to the heating demand.
