Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural greenhouses, in particular to a window opening device for greenhouses. Background Art

[0002] An agricultural greenhouse is a facility that is light-permeable and heat-insulating for growing plants. It is mostly used for growing or raising seedlings of thermophilic vegetables, flowers, trees and other plants in low-temperature seasons. In order to ensure the ventilation effect in the greenhouse, it is generally necessary to set a skylight on the top of the greenhouse. However, in the prior art, the skylight is usually hinged on the top of the greenhouse, and the opening angle of the skylight is generally within the range of 40-90 degrees. Since the wind direction outside is uncertain, if the wind direction outside blows toward the skylight from the hinged side of the skylight, so that the skylight blocks the flow of air from the outside, the ventilation effect of the greenhouse will be affected. Therefore, it is urgent to study a window opening device for the greenhouse in order to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1:

[0023] See also Figure 1-2 As shown, the utility model is a window opening device for a greenhouse, comprising a window frame 1 and a supporting frame 2 arranged parallel to the window frame 1; a protective glass 3 is fixed parallel to the inner side of the supporting frame 2; a lifting mechanism 4 is connected to the supporting frame 2; the lifting mechanism 4 is installed on the window frame 1; the lifting mechanism 4 can adjust the relative distance between the window frame 1 and the supporting frame 2. When in use, by installing the window frame 1 on the top of the greenhouse and adjusting the relative distance between the window frame 1 and the supporting frame 2 by using the lifting mechanism 4, the protective glass 3 does not block the airflow from any direction outside after the greenhouse window is opened, thereby effectively ensuring the ventilation effect of the greenhouse.

[0024] Among them Figure 3-4 As shown, the four edges of the window frame 1 are welded with mounting blocks 5 in parallel; the mounting blocks 5 are arranged on a surface of the window frame 1 away from the carrier frame 2; and a surface of the mounting block 5 close to the carrier frame 2 is provided with a receiving hole 501 for installing a bolt. When in use, the window frame 1 is arranged in the opening for installing the skylight at the top of the shed, and the bolts are passed through the receiving hole 501 to connect the window frame 1 with the top frame of the shed, thereby effectively ensuring the installation efficiency of the entire device.

[0025] Among them Figure 3As shown, an insect-proof net 6 parallel to the protective glass 2 is welded on a surface of the window frame 1 away from the supporting frame 2. When in use, by welding the insect-proof net 6 on a surface of the window frame 1 away from the supporting frame 2, it can effectively prevent external insects from entering the greenhouse from the inner side of the window frame 1 after the protective glass 3 is away from the window frame 1.

[0026] Among them Figure 3 As shown, a sealing strip 7 made of silicone is bonded to the inner edge of the window frame 1; the sealing strip 7 is arranged on a surface of the window frame 1 close to the carrier frame 2; and one surface of the sealing strip 7 can collide with one surface of the carrier frame 2. When in use, by arranging the sealing strip 7 on the inner edge of the window frame 1 and arranging the sealing strip 7 on a surface of the window frame 1 close to the carrier frame 2, when the distance between the protective glass 3 and the window frame 1 is the shortest, one surface of the sealing strip 7 collide with one surface of the carrier frame 2, thereby ensuring the blocking effect on the inner side of the window frame 1.

[0027] Embodiment 2:

When in use, the servo motor 407 drives the second pulley 406 to rotate, prompting the first pulley 405 to drive a screw sleeve 401 to rotate, and then the first sprocket 403 and the chain 404 drive the four screw sleeves 401 to rotate synchronously, prompting the four screw rods 402 to move synchronously, thereby adjusting the relative distance between the window frame 1 and the supporting frame 2; at the same time, by arranging the second sprocket 401 on two adjacent screw sleeves 401, the second sprocket 410 is meshed with the chain 404, and the second sprocket 410 is arranged on the outside of the chain 404, which can effectively ensure the tension of the chain 404, thereby ensuring the stability of the transmission between the four first sprockets 403.
