Description

Technical Field

[0001] This utility model relates to the field of greenhouse technology, and more specifically, to a butterfly-shaped continuous ventilation structure for the top of a large-span multi-span film greenhouse. Background Technology

[0002] In some greenhouses, windows need to be opened in the top for ventilation and dehumidification. However, existing greenhouse top window ventilation structures are mostly outward-opening or use film rollers to close the top windows. When the greenhouse area is large, the area of ​​the top windows is often increased. Due to the excessively large window area, the windows will sway under the influence of wind during ventilation, and opening and closing them is not very convenient. To solve this problem, we propose a butterfly-shaped continuous ventilation structure for the top of large-span multi-span film greenhouses. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a butterfly-shaped continuous ventilation structure for the top of a large-span multi-span film greenhouse. It has the advantages of folding and opening windows to reduce the area of ​​the windows that are erected when opening and closing, thereby alleviating the swaying of the windows caused by wind, and making the windows more stable during the opening and closing process.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a butterfly-shaped continuous ventilation structure for the top of a large-span multi-span film greenhouse, comprising:

[0005] The greenhouse roof frame has two sets of plastic films symmetrically arranged on it, and a top plate is fixedly connected between the two sets of plastic films. Several sets of ventilation openings are opened on the plastic films, and several sets of slide rails are fixedly connected to the plastic films.

[0006] An opening and closing mechanism, wherein the opening and closing mechanism is disposed on a plastic film;

[0007] The drive mechanism is mounted on the greenhouse roof frame;

[0008] The opening and closing mechanism includes two sets of rotating shafts. Both ends of the two sets of rotating shafts are rotatably connected to the two sides of the top plate. A drive gear is fixedly sleeved on an adjacent end of each set of rotating shafts, and the two sets of drive gears are meshed together. Several sets of first baffles are fixedly sleeved on the rotating shafts. A second baffle is provided on the surface of each first baffle. A hinge shaft is rotatably sleeved between the first baffles and the second baffles. The first baffles and the second baffles are hinged to each other through the hinge shaft. Connecting shafts are rotatably connected to the two sides of the bottom of the second baffles. Sliding blocks are rotatably sleeved on the surface of the connecting shafts. Two adjacent sets of second baffles are rotatably connected to a set of sliding blocks through the connecting shafts. The sliding blocks are slidably connected to the inner wall of the slide rail.

[0009] As a preferred embodiment of this utility model, a fixed chamber is fixedly connected to the greenhouse roof frame, a drive motor is fixedly installed on the inner wall of the fixed chamber, a worm gear is fixedly connected to the output end of the drive motor, a worm wheel is meshed on the worm gear, and the worm wheel is fixedly connected to the surface of a set of drive gears.

[0010] As a preferred embodiment of this utility model, baffles are fixedly installed on the front, back, left and right sides of the top of the vent.

[0011] As a preferred embodiment of this utility model, a number of limiting blocks are fixedly connected to the plastic film, and the limiting blocks are fixedly connected to the upward end of the slide rail.

[0012] As a preferred embodiment of this utility model, water guide strips are fixedly connected to the surfaces of opposite sides of the plastic film, and grooves are formed on the inner wall of the water guide strips.

[0013] As a preferred embodiment of this utility model, the slide rail and the stop block are made of lightweight stainless steel.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model, by setting a first baffle, a second baffle, a slide rail, and a sliding block, allows the first baffle to drive the second baffle to rotate around the hinge axis when the rotating shaft rotates. At the same time, the second baffle drives the sliding block to slide along the inner wall of the slide rail through the connecting shaft. During this rotation, the second baffle and the first baffle will release the closure of the ventilation opening. Due to the setting of the slide rail, the second baffle will be more stable during its movement, thereby realizing the folding and opening of the window and reducing the area of ​​the window standing up when opening and closing. This alleviates the swaying of the window caused by wind force and makes the window more stable during opening and closing.

[0016] 2. This utility model is designed with a drive motor, a worm, a worm wheel, and drive gears. When the drive motor starts, the worm will rotate and drive the worm wheel to rotate. This, in turn, drives another set of drive gears to rotate through a set of drive gears. At this time, the two sets of rotating shafts will rotate in opposite directions, thereby driving the first baffle to rotate around the rotating shaft as the center, thus facilitating the control of the rotation and opening of the first baffle.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 4 As shown, this utility model provides a butterfly-shaped continuous ventilation structure for the top of a large-span multi-span film greenhouse, comprising:

[0024] Greenhouse roof frame 1, two sets of plastic films 2 are symmetrically arranged on the greenhouse roof frame 1, a top plate 4 is fixedly connected between the two sets of plastic films 2, several sets of ventilation openings 3 are opened on the plastic films 2, and several sets of slide rails 11 are fixedly connected to the plastic films 2.

[0025] An opening and closing mechanism is provided on the plastic film 2;

[0026] The drive mechanism is mounted on the greenhouse roof frame 1;

[0027] The opening and closing mechanism includes two sets of rotating shafts 5. Both ends of the two sets of rotating shafts 5 are rotatably connected to the two sides of the top plate 4. A drive gear 17 is fixedly sleeved on the adjacent end of each set of rotating shafts 5. The two sets of drive gears 17 are meshed together. Several sets of first baffles 6 are fixedly sleeved on the rotating shafts 5. A second baffle 8 is provided on the surface of each first baffle 6. A hinge shaft 7 is rotatably sleeved between the first baffle 6 and the second baffle 8. The first baffle 6 and the second baffle 8 are hinged together by the hinge shaft 7. A connecting shaft 9 is rotatably connected to both sides of the bottom of the second baffle 8. A sliding block 10 is rotatably sleeved on the surface of the connecting shaft 9. Two adjacent sets of second baffles 8 are rotatably connected to a set of sliding blocks 10 through the connecting shaft 9. The sliding block 10 is slidably connected to the inner wall of the slide rail 11.

[0028] When the rotating shaft 5 rotates, the first baffle 6 will drive the hinge shaft 7 to move during the rotation, which in turn will drive the second baffle 8 to rotate around the hinge shaft 7. At the same time, the second baffle 8 will drive the sliding block 10 to slide along the inner wall of the slide rail 11 through the connecting shaft 9 during the rotation.

[0029] Among them, a fixed chamber 13 is fixedly connected to the greenhouse roof frame 1, a drive motor 14 is fixedly installed on the inner wall of the fixed chamber 13, a worm gear 15 is fixedly connected to the output end of the drive motor 14, a worm wheel 16 is meshed on the worm gear 15, and the worm wheel 16 is fixedly connected to the surface of a set of drive gears 17.

[0030] When the drive motor 14 starts, the worm gear 15 will drive the worm wheel 16 to rotate during the rotation process, which in turn drives a set of drive gears 17 to rotate. At this time, one set of drive gears 17 will drive another set of drive gears 17 to rotate, which in turn drives the two sets of rotating shafts 5 to rotate in opposite directions.

[0031] Among them, baffles 12 are fixedly installed on the front, back and left and right sides of the top of the ventilation opening 3.

[0032] Due to the setting of the baffle 12, rainwater will be prevented from leaking down and flowing into the greenhouse from the vent 3 after the window is closed.

[0033] Among them, several sets of limiting blocks 19 are fixedly connected to the plastic film 2, and the limiting blocks 19 are fixedly connected to the upward end of the slide rail 11.

[0034] The setting of limit block 19 will limit the running trajectory of sliding block 10.

[0035] Among them, water guide strips 18 are fixedly connected to the opposite sides of the plastic film 2, and grooves are provided on the inner wall of the water guide strips 18.

[0036] The water guide strip 18 will guide the rainwater on the plastic film 2, thereby preventing rainwater from falling from the top of the greenhouse entrance.

[0037] The slide rail 11 and the stop block 12 are made of lightweight stainless steel.

[0038] Due to the materials of the slide rail 11 and the stop block 12, the pressure on the top of the greenhouse will be reduced, thereby enhancing the stability of the greenhouse.

[0039] Working principle and usage process of this utility model:

[0040] When the greenhouse roof window needs to be opened, the drive motor 14 is started. The worm gear 15 rotates, driving the worm wheel 16 to rotate, which in turn drives another set of drive gears 17 to rotate. The two sets of rotating shafts 5 rotate in opposite directions, causing the first baffle 6 to rotate around the rotating shaft 5. During this rotation, the first baffle 6 drives the second baffle 8 to rotate around the hinge shaft 7. Simultaneously, the second baffle 8 follows the rotation trajectory of the first baffle 6, and through the connecting shaft 9, drives the sliding block 10 to slide along the inner wall of the slide rail 11. During this movement, the second baffle 8 gradually approaches the first baffle 6, and the second baffle 8 and the first baffle 6 release the closure of the ventilation opening 3. Due to the setting of the slide rail 11, the movement of the second baffle 8 is more stable, thereby realizing the folding and opening of the window, reducing the area of ​​the window standing up when opening and closing, and alleviating the swaying caused by wind. This also makes the window more stable during the opening and closing process.
