Technical Field

The invention relates to the field related to crop storage, in particular to a one-way ventilation anti-light-transmission window.

Background

Root crops refer to plants whose roots and stems are used as edible parts, such as lotus roots, radish, potato root vegetables such as amaranth, rape and scallion, and 90% of leafless vegetables are the same.

At present, rhizome crops are usually stored by arc-shaped storage facilities, but the existing ventilation window cannot realize the function of one-way ventilation, and cannot effectively shield direct sunlight from entering a storage bin, so that the conditions of germination and rot of the crops due to photosynthesis are easily caused.

Disclosure of Invention

Therefore, in order to solve the above-mentioned disadvantages, the present invention provides a one-way ventilation anti-light-transmission window.

The invention is realized in such a way that the one-way ventilation anti-light-transmission window is constructed, the device comprises a window frame, ventilation fan blades and a connecting shaft fixing rod, wherein a plurality of ventilation fan blades are arranged in the window frame, and each ventilation fan blade is rotatably connected with the window frame through the connecting shaft fixing rod.

Preferably, the ventilation fan blade is of a light-penetration-preventing fan structure.

Preferably, the area of the air inlet of the ventilation fan is larger than that of the air outlet.

Preferably, the ventilation fan blades are arranged in more than two positions, and are arranged in the window frame from top to bottom in the same direction and at equal intervals.

The invention has the following advantages: the invention provides a one-way ventilation anti-light-transmission window which is improved, compared with the same type of equipment, and comprises the following improvements:

the advantages are that: according to the one-way ventilation anti-light-transmission window, the ventilation fan is of the anti-light-transmission fan structure, the area of the air inlet of the structure is larger than that of the air outlet, and when the external air pressure is larger than the indoor air pressure, the outer fan blade is automatically closed to achieve the one-way ventilation function; meanwhile, due to the effect of the unidirectional shutter, the direct sunlight can be effectively shielded from entering the storage bin, so that the occurrence of adverse conditions such as germination and rot of crops due to photosynthesis can be avoided.

Detailed Description

The present invention will be described in detail with reference to fig. 1 to 3, and the technical solutions in the embodiments of the present invention will be clearly and completely described, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The invention provides a one-way ventilation anti-light-transmission window which comprises a window frame 1, ventilation fan blades 2 and a connecting shaft fixing rod 3, wherein a plurality of ventilation fan blades 2 are arranged in the window frame 1, and each ventilation fan blade 2 is rotatably connected with the window frame 1 through the connecting shaft fixing rod 3.

Furthermore, the ventilation fan blade 2 is of a light-penetration-proof fan structure, and can prevent sunlight from directly entering the storage bin.

Further, the air inlet area of the ventilation fan blade 2 is larger than the air outlet area, and when the external air pressure is larger than the indoor air pressure, the outer fan blade is automatically closed to achieve the function of one-way ventilation.

Furthermore, the ventilation fan blades 2 are arranged in more than two positions, and are arranged in the window frame 1 from top to bottom in the same direction and at equal intervals.

The invention provides a one-way ventilation anti-light-transmission window through improvement, and the working principle is as follows;

firstly, a plurality of ventilation fan blades 2 are arranged in a window frame 1, and the ventilation fan blades 2 are of a light-penetration-proof fan structure, so that direct sunlight can be prevented from entering a storage bin, and the direct sunlight can be effectively shielded from entering the storage bin, thereby avoiding the occurrence of adverse conditions such as germination and rot of crops due to photosynthesis;

secondly, every fan page or leaf 2 of taking a breath all rotates with window frame 1 through linking axle dead lever 3 and is connected, and fan page or leaf 2 accessible links axle dead lever 3 and overturns, and the air intake area of fan page or leaf 2 of taking a breath is greater than the air outlet area, and when external wind pressure was greater than indoor wind pressure, outside flabellum automatic closure reached the function of one-way taking a breath.

The invention provides a one-way ventilation anti-light-transmission window through improvement, the ventilation fan blade 2 adopts an anti-light-transmission fan structure, the area of an air inlet of the structure is larger than that of an air outlet, and when the external wind pressure is larger than the indoor wind pressure, the outer fan blade automatically closes to achieve the one-way ventilation function; meanwhile, due to the effect of the unidirectional shutter, the direct sunlight can be effectively shielded from entering the storage bin, so that the occurrence of adverse conditions such as germination and rot of crops due to photosynthesis can be avoided.
