Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

Referring to fig. 1-3, an automatic cooling and humidifying vegetable greenhouse comprises a greenhouse body 2 installed on the surface of a planting ground 1, an arc-shaped groove 3 is formed in the side wall of the greenhouse body 2, an arc-shaped fixing frame 14 is fixedly connected to one end of the arc-shaped groove 3, an arc-shaped sliding frame 15 with ferromagnetism is connected in the arc-shaped groove 3 in a sliding mode, a sunshade net 4 compressed into a folded shape is arranged between the arc-shaped fixing frame 14 and the arc-shaped sliding frame 15, a sunshade mechanism used for automatically pulling the sunshade net 4 open under a high-temperature state is installed in the side wall of the lower end portion of the greenhouse body 28, a water storage cavity 5 is formed in the planting ground.

The sun-shading mechanism comprises a sliding cavity 8 arranged in the side wall of the lower end part of the greenhouse body 2, a magnetic sliding plug 13 is connected between the inner walls of the sliding cavity 8 in a sealing and sliding manner, a heat conduction plate 9 is embedded in the lower end part of the inner wall of the greenhouse body 2, a cavity between the magnetic sliding plug 13 and the inner wall of the sliding cavity 8 is filled with a heat evaporation liquid which is in contact with the heat conduction plate 9, and a cooling mechanism for cooling the inside of the greenhouse body 2 in a high-temperature state is arranged in the sliding cavity 8.

It should be noted that the thermal evaporation liquid is dichloromethane, and the boiling point of dichloromethane is 39.75 ℃, so that the thermal evaporation liquid can start to evaporate under the heat transfer effect of the heat conduction plate 9 when the temperature in the greenhouse body 2 reaches nearly 40 ℃ in summer, and further, the heat conduction plate 9 is made of a copper material with a good heat conduction effect, so that the temperature in the greenhouse body 2 can be accurately and quickly transferred to the thermal evaporation liquid, the reaction rate of the sun-shading mechanism is ensured, the high temperature can be accurately and efficiently reacted, and good protection is formed on vegetables.

The cooling mechanism includes air duct 6, the one end of air duct 6 and the one end intercommunication that arc mount 14 was kept away from to smooth chamber 8, the other end and the 5 intercommunication in water storage chamber of air duct 6 just immerse below the 5 liquid levels in water storage chamber, install the first check valve 10 that only allows the air to flow to water storage chamber 5 from smooth chamber 8 in the air duct 6, set up the air inlet 11 with smooth chamber 8 intercommunication on the heat-conducting plate 9, and install in the air inlet 11 and only allow the air to flow to smooth chamber 8's second check valve 12 from the inside of big-arch shelter body 2, the part of planting ground surface position in big-arch shelter body 2 all is equipped with the air vent 7 with water storage chamber 5 intercommunication.

Furthermore, because water storage chamber 5 is located 1 underground position in the plant, consequently, the water and the air in water storage chamber 5 all remain lower temperature throughout, and the one end that air duct 6 is located water storage chamber 5 is located the position below the liquid level all the time, can guarantee like this that the air in smooth chamber 8 is abundant and water contact after getting into water storage chamber 5, make no matter greenhouse body 2, how the circulation of the air of smooth chamber 8 and 5 three departments in water storage chamber flows, the air in water storage chamber 5 all can keep certain humidity, thereby can effectively maintain the humidity condition in greenhouse body 2, build good condition for vegetable growth.

In the invention, when the temperature is too high in summer, the high temperature in the greenhouse body 2 is transferred to the evaporation liquid through the heat conduction plate 9, the hot evaporation liquid is heated and evaporated, the air pressure in the cavity in which the hot evaporation liquid is located is increased, and the magnetic sliding plug 13 is pushed to slide towards the direction far away from the arc-shaped fixing frame 14, so that the arc-shaped sliding frame 15 is driven to slide under the action of magnetic force, and the arc-shaped sliding frame 15 is far away from the arc-shaped fixing frame 14, therefore, the foldable sunshade net 4 between the hot evaporation liquid and the magnetic sliding plug is pulled open to cover the whole greenhouse body 2, so that strong sunlight in summer is shielded, the temperature in the greenhouse body.

In this process, when the smooth stopper 13 of magnetism slides to the direction of keeping away from arc mount 14, can form the extrusion to the air in the smooth chamber 8, thereby the aquatic in the water storage chamber 5 is crowded into to the air in the smooth chamber 8, this part air is sufficient and the increase of humidity with water contact back temperature reduction, and can make the atmospheric pressure increase in the water storage chamber 5, thereby originally microthermal air can follow each air vent 7 and flow in the water storage chamber 5, get into greenhouse body 2, cool down to dispelling the heat in the greenhouse body 2, the required suitable temperature of vegetable plant growth in the greenhouse body 2 has effectively been guaranteed.

When the temperature resumes to the normal atmospheric temperature state in the big-arch shelter body 2, the thermal evaporation liquid is liquefied into liquid again under the effect of heat-conducting plate 9, the internal gas pressure of its place cavity reduces, produce the negative pressure, thereby with magnetism sliding plug 13 pull back original position, at this in-process, smooth chamber 8 is inhaled dry air in big-arch shelter body 2 through air inlet 11, produce the negative pressure in the big-arch shelter body 2, thereby make in the water storage chamber 5 with the moist air that water fully contacted from each air vent 7 entering big-arch shelter body 2 in, make and have certain humidity condition in the big-arch shelter body 2, thereby more do benefit to the growth of this internal plant vegetables of big-arch shelter.

This vegetable greenhouse has realized the circulation flow of three inside air in smooth chamber 8, water storage chamber 5 and big-arch shelter body 2 between high temperature and low temperature conversion, and covers sunshade net 4 automatically when high temperature, and sunshade net 4 is automatic folding when low temperature, has both guaranteed the suitable illumination that vegetables in the big-arch shelter body 2 need, the temperature condition, has also guaranteed the required humidity condition of vegetables growth, and need not to set up the higher electronic equipment self cost of purchase and maintenance cost such as air conditioner cascade.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
