Description

Automatic greenhouse roof window structure convenient to open, close and clean

Technical Field

The utility model relates to the technical field of agricultural greenhouses, in particular to an automatic greenhouse roof window structure convenient to open and close and clean.

Background

Greenhouses are equipment commonly used in agricultural production to provide suitable environmental conditions to promote the growth of crops. The greenhouse is generally provided with a top window at the top of the shed, so that additional ventilation and heat dissipation are provided for the interior of the shed, and meanwhile, the indoor temperature and humidity are regulated, so that the stability and the suitability of the greenhouse environment are ensured. The greenhouse roof window is generally designed to be openable, and can be manually or automatically controlled to be opened or closed.

The existing greenhouse roof window has the following problems in practical application:

1. at present, the top window of most greenhouses is not provided with a screen window, which causes mosquitoes and birds to enter the greenhouse, so that the mosquitoes and birds are difficult to expel, and the mosquitoes and birds can damage the planted crops;

2. in order to avoid the screen window being covered by air pollutants such as dust and the like, the top window provided with the screen window influences ventilation and heat dissipation, so that the screen window is cleaned frequently, but the screen window is difficult to clean due to the higher position of the shed roof.

3. During rainy days, in order to avoid rainwater to get into the big-arch shelter, the staff can close the roof window this moment, but also can lead to ventilation in the greenhouse and heat dissipation limited simultaneously, and moisture and steam can't be effectively discharged to lead to temperature and humidity to rise, high humidity and high temperature are unfavorable to the growth of plant, probably lead to leaf yellowing, plant diseases and insect pests to breed scheduling problem.

In the utility model patent of China patent number 202010842749, a full-automatic skylight is disclosed, the full-automatic skylight comprises a greenhouse frame, a plurality of square-grid-arranged skylights are paved on the top of the greenhouse frame, all or the same row of skylights can be opened through the action of a power part, all positions of the skylights can be opened independently, the skylights consist of an upper window door and a lower window frame, and a blocking net capable of being wound automatically is arranged in the window frame. According to the utility model, the window and door are opened by upward rotation, the window and door drives the window frame to rotate downwards, so that the window frame and the window and door are respectively opened and pulled to two sides, the U-shaped arranged blocking net is used for blocking the exposed window hole for the first time, and the screen net is further arranged on the back of the window frame for blocking the second time, so that birds and mosquitoes cannot fly into the window frame when the skylight of the greenhouse is opened, and the trouble of a planter is avoided.

For this related art patent, the inventors consider this to be: the device is through installing blocking net, though can avoid birds and mosquito to fly into the big-arch shelter, but comparatively inconvenient when clearing up blocking the net, because blocking net is located higher positions such as roof window, need use ladder or other instrument to clear up, increased staff's intensity of labour, if blocking net is not cleared up for a long time, can be covered by air pollution such as dust to influence ventilation and heat dissipation, and blocking net's durability is relatively poor, receives the efflorescence easily and produces the damage, needs periodic replacement and maintenance, has increased cost and work load.

The utility model patent number 201710984685 discloses a rain-proof, bird-proof and wind-proof greenhouse which is mainly used for cultivating fruit trees in the south area. The greenhouse is a single greenhouse or a multi-span greenhouse formed by a plurality of single greenhouses; the single greenhouse comprises a main greenhouse body and a top window arranged at the top of the main greenhouse body; the main shed body comprises a plurality of shed arches and a shed film covering the outer sides of the shed arches; the two sides of the main shed body and the top of the main shed body are respectively provided with a side vent and a top vent; the roof window comprises a plurality of upper arches, support rods arranged at two sides below the upper arches, and an upper canopy film covered outside the upper arches. The side vent and the top vent are respectively covered with a bird-proof insect-proof net, and the outside of the bird-proof insect-proof net is covered with a rolling film. The roof vent is located below the roof window. The rain-sheltering bird-preventing wind-resisting greenhouse provided by the utility model can meet the four-season environmental requirements of fruit tree planting in most southern areas of China, is rain-sheltering, bird-preventing, wind-resisting, rust-preventing, fruit cracking-preventing and bagging-reducing, has simple structure and operation, and can be modified on the basis of the original greenhouse.

For this related art patent, the inventors consider this to be: the device reaches the purpose of preventing birds protection against insects through preventing the fly net at the vent cover, but the bird protection against insects net level setting of top vent department leads to preventing the surface of bird protection against insects net to store up the pollutant more easily, even people birds nest on preventing bird protection against insects net to influence the ventilation and the radiating effect of preventing bird protection against insects net, and need expend the manual work and clear up, it is comparatively troublesome.

Therefore, the utility model provides an automatic greenhouse roof window structure which is convenient to open and close and clean, and solves the problems.
