Description
Technical field
The utility model relates to greenhouse by solar heat technical field, especially a kind of soil thermal storage anti-freezing energy-saving greenhouse by solar heat that is adapted at the application of northern China cold district.
Background technology
Along with optimizing and revising of the economic structue of agriculture, agricultural planting structure has had great variation, especially greenhouse by solar heat by traditional farming type to the fast development of modern agriculture type.In the north, due to very cold, the key of building greenhouse by solar heat is energy-saving heat preserving, has made full use of solar energy source.
In the winter of northern China, particularly late fall or early spring sunlight indoor air temperature exceed the suitable temperature of cultivation, in order not make warm indoor air temperature too high, the general method of leaking informaton that adopts is carried out the interior waste heat of discharge chamber to reduce warm indoor temperature, and be unfavorable for plant growth night or cloudy owing to not having the temperature in solar radiation greenhouse very low.Greenhouse by solar heat runs into the Snowfall of ultralow temperature weather or continuous many days, once boiler heating not in time, often easily causes freeze injury, brings about great losses to agricultural production.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of rational in infrastructure, high insulating effect, waste heat in daytime greenhouse can be stored in soil, be re-used as thermal source night to indoor release, dwindle day and night temperature in greenhouse, be conducive to plant growth, remarkable in economical benefits, is adapted at the soil thermal storage anti-freezing energy-saving greenhouse by solar heat of application in north China.
The purpose of this utility model is achieved in that a kind of soil thermal storage anti-freezing energy-saving greenhouse by solar heat, it comprises body of wall and ceiling, ceiling is by some pairs of film bow members as support frame, and in the inner side of support frame and outside, all fixed plastics film forms duplicature greenhouse by solar heat ceiling; It is characterized in that: in greenhouse, surrounding is underground arranges heat insulation ditch, in heat insulation ditch, lays heat-barrier material; In greenhouse, underground central longitudinal is to middle heat storage tank is set, in greenhouse, underground thing both sides longitudinally arrange respectively east side heat storage tank and west side heat storage tank, between middle heat storage tank and east side heat storage tank and west side heat storage tank, be all communicated with some heat-exchange tubes, middle heat storage tank top arranges air intake cylinder, on air intake cylinder, blower fan is installed, on east side heat storage tank and west side heat storage tank, multiple discharge pipes is set respectively; It also comprises an electric cabinet that starts blower fan according to room temperature control.
The internal diameter of heat-exchange tube is 0.12～0.18 meter, and the horizontal range between heat-exchange tube is 0.4～0.6 meter, and it is 0.4～0.6 meter that heat-exchange tube is laid depth distance greenhouse inner bottom surface height.
In order to improve heat insulation effect, it adopts semi-underground type design form, and warm flooring is lower 0.5～1.2 meter than warm outdoor ground.
Described body of wall comprises side wall body and back wall, and back wall is built and formed by soil heap, and the side section of back wall is trapezoidal, the trapezoidal width of going to the bottom is 4～5 meters, trapezoidal height is 2.3～2.8 meters, and base angle, inner side is 70 °～85 °, and base angle, outside is 50 °～70 °.
In order further to improve Insulation, before room, the southern side of ground arranges Cold-proof Ditch, lays heat insulation material at Cold-proof Ditch.
The utility model compared to the prior art its advantage is:
1) it is when room temperature reach a certain height by day, automatically start blower fan by electric cabinet, make indoor high temperature air enter middle heat storage tank, entered again east side heat storage tank and the west side heat storage tank of both sides by heat-exchange tube by middle heat storage tank, then entered in greenhouse by discharge pipe, hot-air is by heating to soil in heat-exchange tube process, improve soil temperature, heat energy storage, improving soil temperature is conducive to plant growth on the one hand, improve plant products and quality, can reduce on the other hand greenhouse air temperature, make warm indoor temperature be more suitable for plant growth.
2) when not shine upon night, the temperature in greenhouse starts to decline, and at this moment the heat of soil internal reservoir starts to discharge, and has slowed down warm indoor air temperature and has underspeeded, and is conducive to plant growth.
3) at the weather that runs into ultralow temperature or snowfall, temperature indoor temperature is reduced to when will causing freeze injury, electric cabinet starts blower fan automatically, pressure makes heat and the warm room air in soil, stored carry out exchange heat, alleviate the cooling rate of warm room air, avoid boiler heating to cause not in time freeze injury.
4) in greenhouse, surrounding is underground arranges heat insulation ditch, in heat insulation ditch, lays heat-barrier material; Can reduce the soil heat loss that greenhouse heats through accumulation of heat, be conducive to improve the thermal efficiency.
5) it adopts the body of wall of semi-underground type design form and suitable depth, when having ensured the heat-insulating property of body of wall, reduced construction cost, this structure is particluarly suitable for hillside on the sunny side and builds, in excavating semi-underground type greenhouse, soil is directly piled up to body of wall, can adopt excavator to cut the earth, pressing machine or caterpillar tractor suppression, the method of last shaping by stock removal is built thick wall body, construction cost is cheap, and construction speed is fast, high insulating effect.
6) it also has simple in structure, the easy feature of construction, is adapted at the cold area popularizing application of 40 °～45 °, northern China latitude.
