Abstract
The utility model belongs to the technical field of greenhouses, and discloses a greenhouse ventilation device which comprises an S-shaped hook and a chain. The S-shaped hook comprises a fixing part, a connecting part and a containing part which are fixedly arranged in sequence from top to bottom, the fixing part is connected with the chain, and the containing part is connected with the greenhouse film and hooks the bottom of the greenhouse film; one end of the chain is fixedly connected with the film pressing structure, and the other end of the chain freely hangs down; a plurality of small holes are formed in the chain at intervals, and the fixing parts of the S-shaped hooks penetrate through the small holes of the chain to be connected with the chain; the device is simple in structure, low in cost, not prone to damage and convenient to maintain, opening, closing and size of a greenhouse ventilation opening are adjusted by moving the S-shaped hook up and down, operation is easy, the workload is reduced, meanwhile, the device does not damage a greenhouse film, the ventilation quantity of a greenhouse can be adjusted in a multi-stage mode according to ventilation requirements, and the practicability is high. The problem that in the prior art, a greenhouse ventilation device is large in operation workload or complex in structure is solved.
