Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.
Embodiment one
Referring to Fig.1-2, a kind of wind resistance greenhouse bracket, including two first piston pipes that are parallel and being horizontally fixed on ground
1,1 both ends of first piston pipe seal, and are connected between the end of two first piston pipes 1 by connecting rod (not shown) and surround box
Shape, 1 middle part of first piston pipe is vertical and is fixedly connected with second piston pipe 2, and second piston pipe 2 is connected to first piston pipe 1, the
First piston 3 there are two being flexibly connected in one piston tube 1, and two first pistons 3 are symmetrically distributed in the two of second piston pipe 2
Side is connected with second piston 4, filling in the space that second piston 4 and two first pistons 3 are formed in second piston pipe 2
There is hydraulic oil, first piston 3 is fixedly connected with piston rod 5 far from one end of hydraulic oil, and the other end of piston rod 5 is through to first
The outside of piston tube 1 is simultaneously fixedly connected with mounting plate 6, and the portion outboard that piston rod 5 is located in first piston pipe 1 is cased with spring
12, the both ends of spring 12 are connect with the end face of first piston 3 and first piston pipe 1 respectively, and 6 upper end of mounting plate is rotatably connected to branch
Strut 7 is rotatably connected to curved rod 8 between the upper end of two support rods 7, and the middle part of curved rod 8 is run through and slidably connected perpendicular
Bar 9,9 lower end of vertical bar are through in second piston pipe 2 and are fixedly connected with second piston 4, and the upper horizontal of curved rod 8 is equipped with pressure
Plate 10,9 upper end of vertical bar is through pressing plate 10 and is firmly connected with it, and 10 bottom of pressing plate offsets with 8 upper end of curved rod, and on vertical bar 9
End is connected with wing plate 11, and 11 crowning of wing plate is located at its lower end, and in strong wind weather, the speed air flow outside greenhouse is very
Fastly, since the crowning of wing plate 11 is located at its lower end, the air quickly flowed makes wing plate 11 generate downward pressure, and then compresses
Vertical bar 9 moves down, and then compresses the hydraulic oil in second piston pipe 2, since second piston pipe 2 is connected to first piston pipe 1,
And then piston rod 5 is compressed to two sides movement by hydraulic oil, and then so that support rod 7 is turned to heeling condition, and then reduce greenhouse
The windward side of side, while after the side inclination of greenhouse, cooperate its arc top surface, the air blast in greenhouse surface can be will act on
It guides, reduces strong wind to the active force of greenhouse, prevent greenhouse from being blown down.
In this implementation, when playing strong wind, air flows faster on the outside of greenhouse causes the air pressure on the outside of greenhouse lower, supports
When the rotation inclination of bar 7, gap can be generated between support rod 7 and first piston pipe 1, the air in greenhouse can be exported from gap, into
And the air pressure in greenhouse is reduced, so that the draught head inside and outside greenhouse reduces, prevent greenhouse from being thrown, and support rod 7 rotates
While, it will drive the increase of 8 curvature of arc panel, and then reduce the whole height of greenhouse, reduce blocking of the greenhouse to wind, make wind energy
It is walked well by water conservancy diversion, and then damage of the strong wind to greenhouse can be effectively prevent.
In the present invention, curved rod 8 uses elastic steel strip, and can compress elastic steel strip by pressing plate 10 when vertical bar 9 moves down makes
Its deformation reduces its radian, pressure difference inside and outside greenhouse caused by reducing because of its arcuate structure, and then effectively greenhouse is avoided to be lifted
It turns over, improves wind loading rating, while elastic steel strip can restore original form after strong wind stopping, and greenhouse is kept to have higher dome.
Further, 9 upper end of vertical bar and wing plate 11 rotate, and when wind is blown from different directions, wing plate 11 is free to rotate
It goes windward, to make full use of wind-force, and then improves the lower pressure that wing plate 11 generates, reduce the highly effective wind resistance of greenhouse.
Further, the first reinforcing rod is fixedly connected between two support rods 7 ipsilateral and adjacent positioned at greenhouse bracket
(not shown) is fixedly connected with the second reinforcing rod (not shown) between two adjacent curved rods 8, improves the intensity of greenhouse, and
When installing multiple greenhouse brackets, greenhouse bracket can mutually link, and improve the whole wind resistance of greenhouse.
Embodiment two
Referring to Fig. 3-4, it is equipped with cavity in mounting plate 6, and cavity inside is equipped with wind-up roll 13, there is close coiling on wind-up roll
The strip-shaped hole in cavity sidewalls and the end face seal with connecting rod and first piston pipe 1 are run through in sealer 14, the free end of sealing film 14
Connection.
The present embodiment and embodiment one the difference is that, cavity is equipped in mounting plate 6, and cavity inside is equipped with winding
Roller 13, coiling has a sealing film 14 on wind-up roll, strip-shaped hole of the free end of sealing film 14 in cavity sidewalls and with connecting rod and
The end face seal of first piston pipe 1 connects, and when the plant planted in greenhouse, growth needs confined space to keep temperature and humidity
When, due to that can not export the gas in greenhouse in strong wind weather, prevents the temperature and humidity in greenhouse from changing, can lead to
The sealing film 14 freely stretched is crossed, leakproofness of the greenhouse in strong wind weather in it is kept, more embodies by reducing greenhouse height
Carry out windproof importance.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Anyone skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
