Abstract

The utility model discloses a large-span solar greenhouse, which comprises an insulation rear wall, a main frame and double-groove plastic greenhouse films. An overhead insulation guard plate is disposed between the top of the greenhouse and the insulation wall. The main frame is structurally composed of longitudinal large-span arch main supports and transverse horizontal supports. One transverse horizontal support is mounted at the top between two longitudinal large-span arch main supports. Four to six double-groove arch supports are disposed between two longitudinal large-span arch main supports. The upper ends of the double-groove arch supports are connected with the transverse horizontal supports, and the lower ends of the double-groove arch supports are connected with a ground foundation. Parallel transverse bracing steel wires for transverse fixation penetrate the double-groove arch supports and the greenhouse. A hollow plastic film is disposed outside upper clamping grooves of the double-groove arch supports, and a single plastic film is disposed outside lower clamping grooves of the double-groove arch supports. Cold-proof partition plates are disposed underground on the periphery of the interior of the greenhouse. The large-span solar greenhouse has the span reaching 12-14m, so that land utilization rate is increased. The large-span solar greenhouse under multiple-insulation is suitable for cold areas in north China.

Description

Big span greenhouse by solar heat

Technical field: the utility model relates to the industrialized agriculture field, is a kind of big span greenhouse by solar heat specifically.

Background technology: present greenhouse by solar heat mainly contains two kinds, and a kind of is exactly the simple and easy greenhouse that covers single-layer plastic film; A kind of is polyester sunlight board greenhouse.The heat insulation effect of single-layer plastic film is poor, need add thermal insulation quilt separately, has increased investment, shortened the solar irradiation time, moreover it is poor to go back heat insulation effect, and the area that is higher than certain latitude in the north does not reach the requirement of surviving the winter; Be exactly that span is little in addition, general 7-8 rice, land utilization rate is low; Relative surface area is big, and heat storage capacity is poor; Do not have the winter protection ditch to cause ground temperature low, do not have the not congruent defective of temperature regulating facility configuration in the greenhouse.And polyester sunlight board booth cost cost is too high, and heat insulation effect is also very poor, does not reach the requirement of surviving the winter, thereby also is difficult to popularize use.

Summary of the invention: the utility model purpose is to provide a kind of big span greenhouse by solar heat, and its span is designed to 12-14 rice, and it is provided with multiple insulation measure, high insulating effect, be simple and easy, efficiently, modern agriculture facility cheaply.

The utility model greenhouse technology scheme is following:

There are insulation back wall, main frame, two draw-in groove plastic greenhouse film in this greenhouse; Between booth place of rising and insulated wall, establish and rise the insulation backplate; The structure of main frame is to be configured to horizontal flat by vertically big span arch main support; Laterally flat support of the place's of rising installing between two vertically big span arch main supports disposes 4～6 two draw-in groove arch supports between two vertically big span arch main supports, two draw-in groove arch supports upper end is connected with laterally flat support; The lower end is connected with the basis, ground, is provided with many be used for crosswise fixed parallel horizontal and draws steel wire to pass two draw-in groove arch supports to run through the greenhouse; On two draw-in groove arch supports, adorn the hollow plastic film outside the draw-in groove, lower bayonet slot dress single-layer plastic film, the underground cold division board of setting up defences in the surrounding in the greenhouse.

Wall is the outer formation of hollow brick wall addition polymerization polystyrene board heat-insulatation after the above-mentioned insulation.

Above-mentioned booth is risen the insulation backplate bubble Colour light plate of attaching most importance to.

Above-mentioned vertically big span arch main support is the light steelframe of arch, and span is 12～14 meters, is made by angle steel.

Above-mentioned two draw-in groove arch supports are made up of the two draw-in groove framves of arch and drop-down string steel wire and pole.

Above-mentioned laterally flat support is the lightweight steel construction frame, for the upper support structure frame of two draw-in groove arch supports, by angle steel and reinforcement fabrication.

Above-mentioned winter protection division board is to be embedded in 10 centimeters underground thick heavily bubble styrofoam, in depth following 1～1.5 meter.

The advantage of the utility model is: 1, this greenhouse span is big, can reach 12～14 meters, and 7～8 meters of general greenhouse spans enlarge the effective cultivated area in greenhouse, improve land utilization rate.2, multiple insulation setting, insulation hollow wall, underground winter protection division board, draw-in groove is installed the hollow plastic film on two draw-in grooves, and lower bayonet slot is installed single-layer plastic film, plays multi-layer heat preserving and does not establish thermal insulation quilt in addition; Make insulation more reliable, be fit to the north than cold district.

Description of drawings Fig. 1 is the utility model main support cross-sectional view longitudinally;

Fig. 2 is that the utility model is along two draw-in groove arch support cross-sectional view;

Fig. 3 is the utility model overall structure vertical view;

Fig. 4 is the laterally flat supporting structure sketch map of the utility model;

Fig. 5 is the two draw-in groove arch support structure charts of the utility model;

Fig. 6 is two draw-in grooves, the horizontal structure of steel wire figure that draws of the two draw-in groove arch supports of the utility model.

Embodiment is described further the utility model below in conjunction with accompanying drawing.

Can see by Fig. 1～6; There is insulation back wall 1 in this greenhouse, main frame, two draw-in groove plastic greenhouse film, and above-mentioned back wall is made up of hollow brick wall addition polymerization polystyrene board heat-insulatation skin; Between booth place of rising and insulated wall, establish and rise insulation backplate 2; It is heavily to steep Colour light plate, and in order to reach the purpose of big span, its main frame is set to: utilize vertically big span arch main support 3 and laterally flat support 5 to be the main support structure; Its span is 12～14 meters; Laterally flat support 5 of the place's of rising installing between two vertically big span arch main supports, 5 two draw-in groove arch supports 6 of configuration between two vertically big span arch main supports, two draw-in groove arch supports upper end is connected with laterally flat support; The lower end is connected with the basis, ground; Be provided with the many parallel horizontal steel wires 7 that draw, pass two draw-in groove arch supports and run through the greenhouse, in order to the stability of whole frame; Dress hollow plastic film outside the draw-in groove 10 on two draw-in groove arch supports, lower bayonet slot 11 dress single-layer plastic film play the multi-layer heat preserving effect, and do not establish thermal insulation quilt in addition; The underground cold division board 4 of setting up defences in surrounding in the greenhouse, this plate is to be embedded in 10 centimeters underground thick heavily bubble styrofoam, in depth following 1～1.5 meter.

Can see that by Fig. 5～6 above-mentioned two draw-in groove arch supports 6 are made up of the two draw-in groove framves of arch and drop-down string steel wire 9 and pole 8; At two draw-in grooves 10, to establish the many parallel horizontal steel wires 7 that draw between 11 fixing.
