[0013] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0014] like Figure 1As shown, the biomass-assisted solar heating system of this embodiment includes a hot water storage tank 1, and the connection ends of the hot water storage tank 1 are respectively connected to an outdoor solar circulation system 2 and a heat plate exchange circulation system 3; the outdoor solar circulation system 2 includes an outdoor solar heat collecting tube 4, the input end of the outdoor solar heat collecting tube 4 is connected to a solar circulation pump 5, and the output end of the outdoor solar heat collecting tube 4 is connected to the water supply end of the hot water storage tank 1 through a valve, and the output end of the outdoor solar heat collecting tube 4 is connected to the return water end of the hot water storage tank 1 through a valve; the heat plate exchange circulation system 3 includes a heat plate exchange 6, and the input end of the heat plate exchange 6 is connected to the heat plate exchange circulation pump 5. The heat exchanger circulation system 3 is connected to the indoor heat dissipation circulation system 8; the indoor heat dissipation circulation system 8 includes a biomass boiler 9, the input end of the biomass boiler 9 is connected to the output end of the heat exchanger 6, the output end of the biomass boiler 9 is connected to the light heating circulation pump 10 through a valve, the input end of the light heating circulation pump 10 is connected to the indoor radiator or floor heating 11, and the output end of the indoor radiator or floor heating 11 is connected to the input end of the heat exchanger 6.

[0015] refer to Figure 1 A water level and water temperature measuring instrument 12 and an electric auxiliary heating 13 are built into the hot water storage tank 1, and the water level and water temperature measuring instrument 12 and the electric auxiliary heating 13 are used in conjunction with each other.

[0016] This embodiment can detect the water temperature and water volume inside the hot water storage tank 1 and can perform auxiliary heating on the water temperature inside the hot water storage tank 1 by providing the water level and water temperature measuring instrument 12 and the electric auxiliary heating 13 .

[0017] refer to Figure 1 The input end of the hot water storage tank 1 is connected to a solenoid valve 14 , and the solenoid valve 14 is used in conjunction with a water level and water temperature measuring instrument 12 , and the input end of the solenoid valve 14 is connected to a tap water source 15 .

[0018] In this embodiment, through the arrangement of the solenoid valve 14 and the tap water source 15, when the water level and water temperature measuring instrument 12 detects that the water level of the hot water storage tank 1 is lower than the set water level, the solenoid valve 14 opens to automatically replenish the tap water source 15, and when the water level reaches the set water level, the solenoid valve 14 closes to stop replenishing water.

[0019] refer to Figure 1 The outside of the hot water storage tank 1 is electrically connected to an automatic control box 16, and the automatic control box 16 has a built-in control system, and the control system is electrically connected to multiple valves respectively. Multiple temperature monitoring points are arranged inside the control system, and the multiple temperature monitoring points are respectively used in conjunction with the outdoor solar energy circulation system 2, the heat plate exchange circulation system 3 and the indoor heat dissipation circulation system 8.

[0020] This embodiment can perform long-distance data transmission and real-time control of each circulation system by setting up the automatic control box 16, the control system and the temperature monitoring points and utilizing the automatic control box 16 with a data collector and a network base station for remote data transmission.

[0021] refer to Figure 1 The input end of the biomass boiler 9 is connected to an automatic feeding device 17.

[0022] The present embodiment can facilitate the automatic replenishment of biomass to the biomass boiler 9 by setting up the automatic feeding device 17, that is, the biomass mainly refers to: corn stalks, sorghum stalks, cotton stalks, branches, wheat straw and other common crops and plant stalks in rural areas that have been simply crushed.

[0023] refer to Figure 1 The number of outdoor solar heat collecting tubes 4 and indoor radiators or floor heating 11 is several, and the several outdoor solar heat collecting tubes 4 and indoor radiators or floor heating 11 are connected in series respectively.

[0024] This embodiment can improve the heat absorption and heating effects of the device by disposing a plurality of outdoor solar heat collecting tubes 4 and indoor radiators or floor heating 11.

[0025] When the outdoor solar energy circulation system 2 of the utility model is used, after the sun comes out during the day, when the control system detects through the temperature monitoring point that the water temperature of the outdoor solar energy collecting tube 4 rises to the set temperature, the solar energy circulation pump 5 starts to work and circulates the hot water in the outdoor solar energy collecting tube 4 to the hot water storage tank 1 for storage. At this time, the water level and water temperature measuring instrument 12 can detect the water level and water temperature in the hot water storage tank 1 in real time. When the water level and water temperature measuring instrument 12 detects that the water level in the hot water storage tank 1 is lower than the set water level, the solenoid valve 14 opens and starts to automatically replenish the tap water source 15. When the water level reaches the set water level, the solenoid valve 14 closes and stops replenishing water, thereby controlling the water level to be kept within the normal range. When it is rainy or at night when there is no solar energy, the antifreeze mode can be set through the automatic control box 16, and the solar energy circulation pump 5 will enter the energy-saving and power-saving mode to perform intermittent circulation work; At this time, the heat plate exchange circulation system 3 transfers the hot water in the hot water storage tank 1 to the indoor heat dissipation circulation system 8 through the heat plate exchanger 6. The indoor heat dissipation circulation system 8 circulates the heat through the heat plate exchanger 6 through the light heating circulation pump 10 to the indoor radiator or floor heating 11, thereby achieving the effect of heating the room. When the indoor temperature rises to reach the set temperature, the light heating circulation pump 10 stops working. When the temperature is lower than the set temperature, the light heating circulation pump 10 starts to circulate in sequence. At this time, due to use in rainy weather or at night, the temperature in the hot water storage tank 1 is lower than the set temperature. At this time, the control system automatically turns on the biomass boiler 9 auxiliary heat source to heat the indoor circulating water. When the indoor temperature reaches the set temperature, the control system will stop the biomass boiler 9 auxiliary heat source, and circulate control in sequence to keep the water supply temperature at the set temperature to achieve the heating effect.
