Description

Technical Field

[0001] This utility model relates to the field of soil thermal storage technology, specifically a soil thermal storage type solar heating integrated system. Background Technology

[0002] Two concentric circular pipes are used as heat transfer pipes. The end of the outer pipe is closed. During the heat storage stage, the heat transfer medium enters the inner pipe from the distribution pipe and flows out from the outer pipe, forming a closed loop to transfer heat to the soil and store it. During the heating, the water flow direction in the pipe is reversed. In order to reduce heat loss, a polystyrene foam insulation layer of a certain thickness is laid on the ground. In order to ensure heat transfer performance, there should be good contact between the outer pipe and the surrounding soil. In order to achieve the effect of temperature stratification in the soil, the heat transfer medium should be kept at a low flow rate in the pipe.

[0003] For example, patent document CN 222322317 U discloses a solar greenhouse system for long-term solar energy storage and heating using soil-hydrated salts. This system includes a greenhouse, a solar collector circulation unit, a soil-hydrated salts heat storage and heating unit, and an automated control unit. This system innovatively combines solar energy collection with soil-hydrated salts composite heat storage and heating technology to achieve effective seasonal storage and utilization of solar energy. During the non-heating season when solar energy is abundant, the system efficiently collects solar energy through collectors and converts it into heat energy. This heat energy is then stored using the soil-hydrated salt mixture and the soil's high heat storage capacity and excellent thermal stability. During the heating season, the stored heat energy is released into the greenhouse, providing a stable heat source for crop growth. This system has advantages such as high energy efficiency, environmental friendliness, and sustainability, and is suitable for solar greenhouses under various climatic conditions. It is of great significance for promoting green agriculture and the application of renewable energy.

[0004] However, in practice, due to its structural limitations, this structure can only be used for simple soil-laying heat storage, which has low soil heating efficiency. At the same time, the equipment cannot perform efficient flow heating of solar energy, which cannot meet the daily use needs. Therefore, it is urgent to design a soil-storage type solar heating integrated system to solve the above problems. Summary of the Invention

[0005] The purpose of this utility model is to provide a soil-storage type solar heating integrated system to solve the problems mentioned in the background art. In actual operation, due to the limitations of its own structure, the existing structure can only adopt a simple soil-laying heat storage operation, which has low soil heating efficiency. At the same time, the equipment cannot perform efficient flow heating operation of solar heating, and cannot meet the daily use needs.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a soil-storage type solar heating integrated system, including a conical frame, a bottom plate fixedly connected to the bottom of the conical frame, an insulated inner liner provided on the inner wall of the conical frame, and a heat storage groove opened inside the conical frame and the insulated inner liner;

[0007] A hot water storage tank is fixedly connected to the bottom end of the docking base plate. Infusion side frames are fixedly connected to both sides of the hot water storage tank. A control pump is fixedly connected to one end of the infusion side frame. An infusion pipe is fixedly connected to the top end of the control pump.

[0008] Preferably, a heat storage plate is provided at the top of the infusion tube, and a heat storage unit is fixedly connected to the bottom of the heat storage plate.

[0009] Preferably, the heat storage plate is fixedly connected to both sides of the heat storage plate, and the surface of the heat storage plate is provided with solar tube arrays.

[0010] Preferably, the hot water storage tank has a water storage tank inside, and water storage side grilles are provided on both sides of the inner wall of the water storage tank.

[0011] Preferably, a heat-conducting plate is uniformly and fixedly connected to the bottom end of the docking base plate.

[0012] Preferably, the inner wall of the heat-insulating inner liner is uniformly provided with heat-conducting strips.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This soil-based solar heating system, through its conical frame, connecting base plate, insulated inner tank, heat storage tank, hot water storage tank, water storage trough, heat conduction plate, and heat conduction strips, enables more efficient and uniform soil-based solar heating operation. In actual use, the operator first lays the soil for heat storage inside the heat storage tank of the conical frame, and then installs the entire conical frame inside the hot water storage tank via the connecting base plate. At this point, the temperature-controlled solar hot water inside the hot water storage tank can be evenly transferred through the heat conduction plate at the bottom of the connecting base plate, stably heating the soil evenly along the heat conduction strips on the inner wall of the conical frame and the insulated inner tank, completing the heat storage operation. This also allows the equipment to operate more evenly and stably, demonstrating the practicality of the equipment design.

[0015] This soil-based solar heating system, through its conical frame, hot water storage tank, liquid delivery side frame, liquid control pump, liquid delivery pipe, heat storage plate, heat storage unit, connecting side plate, solar tube assembly, and water storage side grid, further enhances the overall performance of the equipment. In daily use, operators can connect the heat storage plate to the liquid control pump via the liquid delivery pipes at the bottom of the connecting side plates. Activating the liquid delivery side frames on both sides of the hot water storage tank, in conjunction with the water storage side grids on both sides of the inner wall of the tank, circulates the stored hot water within the tank. This ensures the hot water is evenly heated at the heat storage unit at the bottom of the heat storage plate, working in conjunction with the conical frame to complete the soil heat storage operation. This improves the equipment's effectiveness in utilizing solar energy and demonstrates the comprehensiveness of its design. Attached Figure Description

At this time, the temperature-controlled solar hot water inside the hot water storage tank 5 can be uniformly transferred through the heat-conducting plate 15 at the bottom of the bottom plate 2.

[0024] A hot water storage tank 5 is fixedly connected to the bottom end of the bottom plate 2. Infusion side frames 6 are fixedly connected to both sides of the hot water storage tank 5.
