Background

The sunlight greenhouse is an energy-saving sunlight greenhouse, is also called a greenhouse and consists of two side gable walls, a maintenance back wall body, a supporting framework and a covering material. Is a unique greenhouse type in northern areas of China. The solar greenhouse is a greenhouse which is not heated indoors, heat storage and release are realized by absorbing solar energy through the rear wall body, and a certain indoor temperature level is maintained so as to meet the growth requirement of vegetable crops. (some farmers also add heating measures in the greenhouse, such as a furnace, a boiler and a heating pipe, or heat preservation measures at night, such as a roller shutter quilt and the like.

However, in the traditional passive heat accumulation and release mode, the heat energy accumulation and release process is slow, the accumulated and released heat is limited, the heat release process is uncontrollable, and the phenomena of low temperature and freeze injury are often caused at night in winter, so that the yield and the quality of crops are influenced.

SUMMERY OF THE UTILITY MODEL

In order to achieve the purpose, the utility model adopts the following technical scheme:

the utility model provides a sunlight greenhouse initiative is held and is released thermal system, includes heat accumulation cask and a plurality of heat collection and release board, the fixed intercommunication in bottom of heat collection and release board has outlet pipe and inlet tube, and is a plurality of through the wet return intercommunication between the outlet pipe, the one end of wet return is linked together with the end of intaking of heat accumulation cask, through the delivery pipe intercommunication between a plurality of inlet tubes, the one end of delivery pipe and the play water end intercommunication of heat accumulation cask, the one end threaded connection that the delivery pipe is located the heat accumulation cask has the immersible pump.

Preferably, the top and the bottom of the heat collecting and releasing plates are fixedly connected through a bracket.

Preferably, the top of the water outlet pipe is in threaded connection with an exhaust valve.

Preferably, one end of the water supply pipe close to the hot water storage bucket is in threaded connection with a control valve.

Preferably, the heat collecting and releasing plate is made of aluminum alloy, and the surface of the heat collecting and releasing plate is subjected to matte black plastic spraying treatment.

Preferably, the heat collecting and releasing plate has a width of 1m and a height of 1.8 m.

Has the advantages that:

the solar greenhouse utilizes the fluid medium circulating in the heat collecting and releasing plate to continuously absorb and accumulate the solar radiation energy reaching the surface of the wall body in the daytime, and releases heat through the circulation of the fluid at night, so that the heat energy accumulation and release efficiency is doubled, the temperature of the sunlight greenhouse in winter and at night is obviously improved, the thickness of a north wall can be effectively reduced, and the light and the simplification of the greenhouse structure are realized.
