Description

Technical Field

[0001] The utility model relates to the technical field of greenhouse, in particular to a steel-frame type solar greenhouse roll-up quilt type ventilation hole adjusting device. Background Technique

[0002] In plateau cold regions, greenhouse is a necessary condition for people to get fresh vegetables. However, the existing greenhouses are costly, have a small light-receiving area, and a small space area inside the shed, which is not convenient for people to cultivate.

[0003] Most of the frames of the currently widely used solar greenhouses are made of wooden structures or steel structures, mainly composed of beams, columns and brackets. Especially, the beam, column and bracket structures of the steel structure are complex, consume a lot of steel, have a high manufacturing cost, a relatively low light transmittance, poor wind and snow pressure resistance, and there are columns evenly distributed in the greenhouse, occupying the usable space and being very inconvenient to use, resulting in a high production input cost and low economic benefits.

[0004] A patent with a publication number of CN201617047U is disclosed in the prior art. The solution includes a front roof suspended combined steel frame of a solar energy-saving greenhouse. The front roof suspended combined steel frame is composed of evenly distributed arc-shaped single-tube steel frames and steel wires matched and connected with them. A ridge installation clamp is arranged at the upper end of the arc-shaped single-tube steel frame, and a connecting seat is arranged at its lower end. Steel wire fixing brackets are evenly arranged on the arc-shaped single-tube steel frame. The ridge installation clamps at the upper ends of each arc-shaped single-tube steel frame are respectively fixedly connected with the front eaves, and the connecting seats at their lower ends are respectively fixedly connected with the fixed seats on the ground. The two ends of the tightened steel wires are respectively matched with the steel wire fixing brackets of each arc-shaped single-tube steel frame, and are respectively fixedly connected with each arc-shaped single-tube steel frame through steel wire fixing frames. The structure is reasonable, light, easy to install, has good snow pressure and wind resistance performance, high light collection efficiency, no columns on the greenhouse cultivation surface, high utilization rate of the planting area, and low manufacturing cost.

[0005] The existing device gradually exposes the deficiencies of the prior art during use, mainly manifested in the following aspects:

[0006] First, when the existing steel-frame type solar greenhouse is in use, the operator pulls the pull rope inside the shed to adjust the opening size of the ventilation hole. Since the ventilation hole is movable, when there is a strong wind, the wind is likely to lift and blow the film from the ventilation hole, resulting in damage to the film and increasing the planting cost.

[0007] Second, the ventilation hole needs to be ventilated regularly every day to ensure the normal growth of crops. This makes it easy for rainwater to enter the greenhouse along the ventilation hole in rainy weather, which has a certain impact on the greenhouse plants and facilities.

[0008] In summary, it can be seen that there are obvious inconveniences and defects in the existing technology in actual use, so it is necessary to improve it. Utility Model Content

A film rolling roller is detachably and rotatably arranged on the top of the support frame. The rear end part of the rain-proof film is wound on the film rolling roller, and the front end part of the rain-proof film is connected to the sliding component. The sliding component is slidably installed on the support frame.

[0014] As an optimized scheme, the sliding component is arranged to slide obliquely downward towards the front end of the steel-frame greenhouse main body, and an inclined rain guiding surface is formed on the upper surface of the rain-proof film.

[0015] As an optimized scheme, two support sleeves are detachably arranged in parallel at the upper end part of the support frame. Both ends of the film rolling roller are rotatably inserted into the support sleeves.

[0016] As an optimized scheme, a fixing knob is threadedly connected to the support sleeve along the radial direction, and the end of the fixing knob abuts against the film rolling roller.

[0017] As an optimized scheme, an insertion groove is opened at the upper end part of the support frame, and an insertion column inserted into the insertion groove is fixedly connected to the lower surface of the support sleeve.

[0018] As an optimized solution, the sliding assembly includes sliding rods arranged in parallel. On the support frame, sliding sleeves are fixedly connected to correspond to each of the sliding rods obliquely. The sliding rods are slidably inserted into the sliding sleeves. A connecting seat is fixedly connected between the front ends of the two sliding rods. The front end of the rain shelter film is detachably connected to the connecting seat.

[0019] As an optimized solution, a connecting groove is formed on the side wall of the connecting seat facing the rain shelter film. The front end of the rain shelter film is wound around a connecting plate, and the connecting plate is inserted into the connecting groove.

[0020] As an optimized solution, a plurality of fastening knobs are connected in parallel by threading at the upper end of the connecting seat. The end of the fastening knob abuts against the upper end of the connecting plate, and the lower end of the connecting plate abuts against the lower surface of the connecting groove.

[0021] As an optimized solution, a turntable is fixedly connected to the end of the fastening knob, and a fastening seat is fixedly connected to the rotating end of the turntable. The lower end of the fastening seat abuts against the upper end of the connecting plate.

[0022] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0023] By setting the ventilation holes to a fixed size and using a rolling machine to adjust the size of the ventilation holes with the heat preservation quilt, the operation of the operator at the bottom of the greenhouse is omitted, saving labor. And by pressing the heat preservation quilt on the ventilation holes, the influence of strong wind weather on the ventilation holes can be overcome, and the film at the ventilation holes can be protected. By arranging a rain shelter film at the top of the greenhouse main body, in rainy weather, the rain shelter film can be pulled out above the ventilation holes to achieve rain shelter operation. The rain shelter film is obliquely arranged, which can divert rainwater and prevent it from gathering on the rain shelter film. When the rain shelter film is in a non-use state, the film can be retracted and reserved by using the sliding assembly and the film rolling roller. BRIEF DESCRIPTION OF THE DRAWINGS
