[0022] Example:

[0023] Please refer to Figures 1-3. This utility model provides the following technical solution:

[0024] A household-based centralized solar heating system includes a solar water heater, a covering device, and an insulation device;

[0025] The solar water heater includes a support frame 1, a water storage tank 2, and a solar tube array panel 3. The support frame 1 is used to support and fix the water storage tank 2 and the solar tube array panel 3. The solar tube array panel 3 is composed of a transfer tube 10 and a heat collection tube 11. Multiple heat collection tubes 11 are provided, and one end of each heat collection tube 11 is inserted into the transfer tube 10. One end of the transfer tube 10 is connected to the water storage tank 2 through a pipe.

[0026] Each collector tube 11 is equipped with a heat insulation device at the other end. The heat insulation device includes a sealing heating ring 12, a heater 13, and a heating wire 14. The sealing heating ring 12 is fitted onto the end of the collector tube 11.

[0027] The heater 13 is fixed near the sealing heating ring 12, and a heating wire 14 is provided at one end of the heater 13 near the sealing heating ring 12. The heating wire 14 is spiral and extends outward.

[0028] The sealing heating ring 12 is composed of two rings, an inner ring and an outer ring. The inner ring is in contact with the inner cavity of the heat collection tube 11, while the heating wire 14 is inserted between the two rings. The heating wire 14 heats the liquid in the heat collection tube 11 through heat conduction.

[0029] A temperature sensor is installed in the inner cavity of the sealed heating ring 12, and the temperature sensor is linked with the heater 13. When the temperature is lower than the preset value, the heating is activated, which can maintain the water temperature in the heat collection tube 11 at night.

[0030] The covering device includes insulation cloth 4, roll 5, slide rail 7 and drive vehicle 8; the roll 5 is set at the bottom of the solar tube array panel 3, and the insulation cloth 4 is stored inside the roll 5. The size of the insulation cloth 4 matches that of the solar tube array panel 3.

[0031] The solar tube array panel 3 is symmetrically equipped with slide rails 7 on the left and right sides, and drive vehicles 8 are symmetrically installed on the slide rails 7. A connecting rod 9 is provided between the two drive vehicles 8. The connecting rod 9 is horizontally fixed to one end of the insulation cloth 4. When the drive vehicle 8 moves upward along the slide rail 7, the connecting rod 9 pulls the insulation cloth 4 upward until the insulation cloth 4 covers the entire solar tube array panel 3.

[0032] The two ends of the roll 5 are equipped with winding machines 6. When the winding machines 6 rotate, they tighten or release the insulation cloth 4. The winding machines 6 and the two drive vehicles 8 are controlled synchronously. The drive vehicles 8 are equipped with photosensitive sensors. The photosensitive sensors are used to detect the light intensity. When the light is insufficient, the drive vehicles 8 are triggered to move and unfold the insulation cloth 4 to cover the solar tube array panel 3.

[0033] When the light intensifies, the rewinder 6 reverses to retract the insulation cloth 4, while the drive vehicle 8 drives the connecting rod 9 and the insulation cloth 4 downwards in sync until the connecting rod 9 abuts against the drum 5. At this point, the insulation cloth 4 has completed its retraction, and the solar tube array panel 3 uses solar energy to heat it again.

[0034] Working principle: The solar tube array panel 3 consists of a transfer tube 10 and multiple heat collection tubes 11. One end of the heat collection tube 11 is inserted into the transfer tube 10 to form a parallel heat collection network. The heat collection tube 11 absorbs solar radiation through vacuum or glass material to heat the heat transfer liquid inside the tube. The high-temperature liquid is pumped into the water storage tank 2 through the water pump in the transfer tube 10 for storage, thus realizing heat energy collection. This is the existing technology and will not be described in detail here.

[0035] The sealing heating ring 12 is fitted onto the other end of the heat collection tube. It consists of two rings, an inner and an outer one. The inner ring is in contact with the liquid inside the tube and transfers heat through thermal conduction.

[0036] Heater 13 transfers heat to sealing ring through spiral heating wire 14, and then heats the liquid in the heat collection tube through heat conduction through inner ring body to prevent the liquid from freezing or heat loss due to excessively low temperature at night.

[0037] The temperature sensor monitors the temperature inside the heat collection tube in real time. When the temperature is detected to be lower than the preset value, the heater 13 is activated to maintain the temperature of the liquid inside the tube within the heat preservation range. The heating wire 14 adopts a spiral design to increase the heat dissipation area and improve the heating efficiency.

[0038] The insulating cloth 4 is stored in the roll 5 and is unfolded and retracted by the drive 8 on the two side slide rails 7 and the connecting rod 9. When the light is insufficient, the drive 8 is triggered to move upward, unfolding the insulating cloth 4 to cover the solar tube array panel 3 and reduce heat radiation to the outside.

[0039] When the light becomes stronger, the rewinder 6 rotates in the opposite direction to recycle the insulation cloth 4, and the solar tube array panel 3 is exposed to sunlight again to collect heat.

[0040] When the drive vehicle 8 moves along the slide rail 7, the connecting rod 9 pulls the insulation cloth 4 to cover the solar tube array panel 3, forming a physical insulation layer; the winding machine 6 is controlled synchronously with the drive vehicle 8 to ensure a smooth winding and unwinding process.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description. Therefore, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model, and no reference numerals in the claims should be construed as limiting the scope of the claims.
