The utility model content:
The technical problems to be solved in the utility model is, at the deficiency that above-mentioned prior art exists, provides a kind of heat riser of new farm plastic greenhouse.This heat riser is to utilize solar energy, can complement one another with the lifting temperature of existing mode of heating to plastic tunnel, can expect to consume to reduce, and reduces production costs; With means relatively economical, environmental protection obtain anti-season or early season agricultural product.
Technical solution of the present utility model is:
A kind of heat riser of farm plastic greenhouse, this device comprises at least one light gathering reflector, the light reflecting mechanism that cell mount, bracing frame are formed, light gathering reflector is put in cell mount, and cell mount and bracing frame are for being rotationally connected.
After adopting above structure, compared with prior art, the utlity model has following advantage: the characteristic of utilizing light gathering reflector, with the photothermal reflectance of the light reflected ray of sunshine in agricultural booth, to improve the temperature in the booth, can complement one another with the lifting temperature of existing mode of heating, reduce and to have expected to consume, reduce production cost plastic tunnel; Thereby with means relatively economical, environmental protection obtain anti-season or early season agricultural product.
As further perfect, the heat riser of described farm plastic greenhouse, also comprise the water circle device of forming by tank, water pump, circulating water pipe, the position of described tank is arranged in the 2-3 rice booth of light reflecting mechanism front, described circulating water pipe is arranged in the booth, the water inlet pipe of described water pump is installed in the tank, and the outlet pipe of water pump is connected with the circulating water pipe water inlet, and the water side of described circulating water pipe is placed in the tank.This structure, mainly be to consider when the interior temperature of booth on daytime has satisfied the temperature needs of crops, the reflection luminous energy of sunshine is accumulated in tank, water in the tank is heated, keep savings to get up heat energy by the water in the tank, to evening, when the air themperature in the booth reduces, with water pump the hot water in the tank is imported in the circulating water pipe again, heat is dispersed in the booth by following the ball water pipe.
As preferably, described light gathering reflector is a Fresnel planar concentrating reflective mirror.Because the reflective mirror that the optically focused of Fresnel planar concentrating reflective mirror and reflecting effect are better than other types.
As improvement, described Fresnel planar concentrating reflective mirror is set to three of left, center, right.This set is more convenient for regulating each piece Fresnel planar concentrating reflective mirror light reflected ray and is concentrated relatively to converge on a bit or to concentrate and diverge in a slice, utilize its light reflected ray to concentrate relatively to converge on a bit water to heat, or utilize its light reflected ray to concentrate relatively to diverge in a slice the air in the booth is heated up tank.
