Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-2, a ventilation device for a vegetable greenhouse comprises an annular frame 1, an annular rail 2 is fixedly connected to the inner wall of the annular frame 1, the section of the annular rail 2 is in an i shape, and the part of a movable fan blade 3 sliding on the annular rail 2 also adopts an i-shaped structure. The i-shaped structure can facilitate the sliding of the moving fan blade 3 on the annular track 2 and prevent the moving fan blade from falling off the annular track 2 when sliding.

The annular track 2 is connected with a plurality of movable fan blades 3 in a sliding mode, the annular frame 1 is fixedly connected with a plurality of fixed fan blades 4, the movable fan blades 3 and the fixed fan blades 4 are of fan-shaped structures, the areas of the fixed fan blades 4 are equal to those of the movable fan blades 3, and the fan-shaped structures can utilize space to the maximum within a certain limit, so that the air intake is maximized.

The fixed fan blades 4 are fixedly connected with an annular block 5, a circular groove 11 is formed in the middle of the annular block 5, a central shaft 6 is arranged in the middle of the circular groove 11, the fixed fan blades 4 are fixedly connected with the central shaft 6, and a clamping mechanism and a limiting mechanism matched with the clamping mechanism are arranged on the central shaft 6.

The block mechanism comprises fixture block 7 and spring 8, and the one end that gag lever post 9 was kept away from to fixture block 7 adopts the arc structure, and draw-in groove 10 inner wall adopts the arc structure, so sets up the roll-off of being convenient for fixture block 7 and draw-in groove 10, prevents that the card from dying, has seted up on the center pin 6 and has accomodate groove 14, accomodates groove 14 and spring 8 fixed connection, spring 8 and fixture block 7 fixed connection, and draw-in groove 10 that uses with fixture block 7 cooperation has been seted up to circular groove 11 inner wall.
