Embodiment

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

See Fig. 1,2, be first embodiment of the present utility model, the present embodiment green house comprises: booth 10, the agent structure of booth 10 is identical with existing structure, do not give unnecessary details at this, wherein, booth 10 tops have keel 20, and keel 20 are equipped with arch bar 22, and keel 20 are formed bow member with arch bar 22, keel 20 are along the length direction setting of booth 10 and be positioned at the centre position, arch bar 22 is covered with collapsible top film 30 along the width setting of booth 10 on the arch bar 22, top film 30 is equipped with film-coiling device 42, film-coiling device 42 is commercially available, can select hand-rail type or chain type film-coiling device for use; By film-coiling device 42 control top film 30 volume, put, it is open or open fully to make the booth top form part, thereby strengthen ventilation, heat radiation, the rainproof effect of booth 10, and, when bad weather can controls booth top film 30 at short notice temporarily, even booth quantity is more, also can tackle fast, generally, the use of top film 30 is very simple, installation cost is lower.

Further, the outer ledge of described top film 30 is wound with axostylus axostyle 40, and film-coiling device 42 is installed on an end of axostylus axostyle 40, and this axostylus axostyle 40 also is the length direction setting along booth 10, because the action of gravity of axostylus axostyle 40, top film 30 can be sagging naturally; By control film-coiling device 42, can drive shaft rod 40 rotations, and then realize top film 30 volume, put.

Further again, arch bar 22 tops are furnished with draw-in groove 24, draw-in groove 24 is commercially available, and draw-in groove 24 is fixing left and right sides top film 30 respectively, and draw-in groove 24 can be fixed in any position of arch bar 22 tops, more convenient is, draw-in groove 24 is installed on the top of booth 10 middle parts, keel 20, and simultaneously, described top film 30 comprises left and right sides two parts, left and right sides top film 30 all adopts same structure, and all to the middle part rolling.

More specifically, the top of described booth 10 has the tripod (not shown) that is used to support axostylus axostyle 40, this tripod is mainly used in and supports axostylus axostyle 40, under the action of gravity of axostylus axostyle 40, top film 30 is sagging naturally, the long-time use, top film 30 may produce slightly deformed, increase tripod and support axostylus axostyle 40, promptly can avoid the distortion of afore-mentioned next top film 30, strengthen result of use; Certainly, the installation site of tripod and installation quantity can be different, do not give unnecessary details at this.

When the temperature in the booth 10 is too high, can pass through film-coiling device 42 rolling top film 30, make booth 10 tops form thermovent, the hot-air in the booth 10 rises and is dispersed into booth 10 outsides by the top thermovent, thereby reduces the heat in the booth 10.

When weather rains, utilize film-coiling device 42 that top film 30 is opened, play rainproof effect.

When strong wind utilizes film-coiling device 42 that top film 30 is partially opened temporarily, can play effect to booth 10 inner pressure releases, strong wind is reduced greatly to the influence of booth 10, reach the wind resistance effect.

See Fig. 3, be second embodiment of the present utility model, present embodiment is further improved on the basis of first embodiment, and wherein, top film 30 tops of described booth 10 also are equipped with collapsible sunshade net 50, sunshade net 50 is equipped with film-coiling device 42, wherein, the outer ledge of described sunshade net 50 is wound with axostylus axostyle 40, and film-coiling device 42 is installed on an end of axostylus axostyle 40, acting among first embodiment of axostylus axostyle 40 is described, do not give unnecessary details at this; This sunshade net 50 is commercially available, both can insect protected, can shelter from heat or light again, and install and use cost reduces greatly; Sunshade net 50 sets film-coiling device 42, can adopt the volume identical with top film 30, put mode, increases the convenience that uses.

More specifically, described booth 10 tops have double-deck bow member, and the bow member of bottom cooperates top film 30, and the bow member of top layer cooperates sunshade net 50, adopt dismantled and assembled structure between two keel 20, sunshade net 50 can be decided according to different requirements with the distance between the top film 30.

Similar with first embodiment, described sunshade net 50 comprises left and right sides two parts, and arch bar 22 tops are furnished with draw-in groove 24, and draw-in groove 24 is fixing left and right sides sunshade net 50 respectively; Sunshade net 50 also can adopt the single piece type structure.

Arch bar 22 spacings of described top layer be bottom arch bar 22 spacings 2-3 doubly, can also reduce cost like this.

Can allow booth 10 interior illumination strengthen 50 rollings of sunshade net; When illumination is excessive, sunshade net 50 can be opened, reduce the temperature in the booth 10; When the temperature in the booth 10 is too high, top film 30 can be opened, and look concrete condition and select sunshade net 50 rollings or open, strengthen heat radiation, ventilation to booth 10.

Aspect production application, can produce, install according to the utility model structure, also can transform existing big booth structure according to the utility model scheme, owing to the utlity model has advantages such as cost is low, easy to install, we can say that the utility model scheme is to promoting that this area agricultural development has positive role.

Certainly, the embodiment of the above, it is preferred embodiments of the present utility model, and unrestricted the utility model practical range, so all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, and all should be included in the utility model claim.
