Abstract

PURPOSE:To provide a transmission adjusting device for quantities of light and heat by fixing a large number of synthetic resin adjusting cylinders disposed in such a manner that the side surface of one cylinder expanded when air is introduced therein can make contact with the side surface of other contiguous adjusting cylinder between two side surface mounting bodies having openings capable of ventilating. CONSTITUTION:Synthetic resin sheet adjusting cylinders 1 disposed in such a manner that the side surface of one cylinder expanded when air is introduced therein can make contact with the side surface of other contiguous adjusting cylinder 1, are fixed in a large number between two side surface mounting bodies 2 made of planar sheets 2a capable of obtaining incident sun rays and having a large number of openings 5a for ventilation at suitable positions for making possible to ventilate air inside and outside hot room H, and an air introducing device 4 is connected to these adjusting cylinder 1. In the stage prior to the air introduction, there are gaps for air passage between the cylinders 1 and openings 5 or 5a are provided. Therefore, ventilation inside and outside the room becomes possible. However, when air is introduced into the room, the cylinder 1 is expanded and makes contact with the contiguous cylinder 1 and the ventilation inside and outside room is interrupted.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device that is installed on the outside of a window of a house, particularly a greenhouse, and is capable of adjusting the amount of incident sunlight and the amount of heat transmitted inside and outside.

Conventionally, transparent or semi-transparent sheets such as vinyl chloride sheets were used for the outer surface of greenhouses, making it impossible to adjust the amount of sunlight entering the greenhouse. Due to the large amount of incident light, the indoor temperature can become abnormally high, and in the winter, indoor heat passes through these sheets with poor insulation properties and escapes outside, resulting in very poor heat retention. It had a structure.

However, the recent rise in oil prices has made it difficult to produce agricultural products cost-effectively unless such agricultural greenhouses are improved.

The present inventors have attempted to solve these problems in the past, and the present invention is aimed at solving the above-mentioned problems. The purpose is to adjust the amount of heat transferred indoors and outdoors, and its gist is that the expanded cylindrical side surface when air is introduced comes into contact with the side surface of another adjustment cylindrical body adjacent to it. A large number of adjustment cylinders made of sheets are fixed in a sandwiched state between two side mounting bodies having openings that allow ventilation, and an air supply device is connected to each adjustment cylinder to adjust the transmission amount of light and heat. It's because it's configured.

The details of the present invention will be further explained based on embodiments shown in the drawings.

In conventional greenhouses H, etc., transparent, translucent, or opaque vinyl chloride or polyethylene sheets are stretched on the interior and exterior interfaces, such as the roof and side walls, to allow sunlight to enter the room. The present invention was developed to be used in place of such greenhouse sheets, or to be installed in other places where it is necessary to adjust the amount of sunlight incident. .

That is, the apparatus of the present invention, as shown in FIG.
A synthetic resin sheet adjustment cylinder 1 arranged so as to be able to come into contact with the side surface is attached to two side mounting bodies 2 shown at the upper and lower positions in the figure.
A large number of air supply devices 4 are fixed in between, and air supply devices 4 are connected to these adjustment cylinders 1.
It is completed by connecting.

Here, the adjustment cylinder 1 is made into a long cylinder shape using a transparent, translucent or opaque synthetic resin sheet used in conventional agricultural greenhouses, It is configured to be able to expand and contract when entering and not entering the greenhouse, and to contact the side surface of another adjacent cylindrical body when expanding, thereby blocking air movement inside and outside the greenhouse H.

As shown in Fig. 2, the side mounting bodies 2 for fixing these cylindrical bodies 1 are designed to allow sunlight to enter and provide ventilation at appropriate locations to allow air to circulate inside and outside the greenhouse H. A flat plate-like sea) 2a with a large number of openings 5a,
Alternatively, as shown in FIG. 1, it is possible to use tape 2b or a string (not shown). When the sheet 2a on a flat plate is used, when the area ratio of the opening 5a to the entire surface of the sheet 28 is relatively large, the sheet 2a does not necessarily need to be formed of a translucent material; When the ratio is relatively small, it is preferable that the material be a translucent material. In addition, when tapes 2b are used, each cylinder 1 is connected by tapes 2b arranged in parallel at appropriate intervals, and when the cylinder 1 is contracted, sufficient ventilation and sunlight enter the cylinder in the cross-sectional direction. Since a possible opening 5 is formed, the tape 2a and the string do not need to be made of a translucent material, and any material can be selected. A large number of cylindrical bodies 1 are fixed to this side mounting body 2 by welding, integral molding, adhesion, or the like.

The air feeding device 4 is provided as shown in FIG. Use what you have.

Therefore, when this device in which a number of adjustment cylinders 1 are clamped and fixed to two side mounting bodies 2.2 is used, for example, on the wall surface of an agricultural greenhouse H, that is, as shown in FIG. 1 or 2. By attaching this device to the )υ-arm of the greenhouse H as shown in Fig. 4 and connecting it to the air supply device 4, the space between the cylinders 1 is closed for air passage before air is supplied. Since there is a gap and the mounting body 2 is provided with the openings 5 and 5a, it is possible to ventilate indoors and outdoors, and the air supply device 4 is connected to each cylindrical body 1.
When air is introduced into the cylindrical body 1, the cylindrical bodies 1 expand as shown in FIG. 3 and come into contact with the adjacent cylindrical bodies 1, thereby blocking ventilation between the inside and the outside.

For example, one mode of realizing the function of the present invention having such a configuration is to expand and contract the cylindrical body 1 in response to changes in the outside temperature and the amount of incident sunlight in the morning, noon, and evening of the day. , it is possible to measure the circulation of air inside and outside the greenhouse H.

That is, in the morning, the cylindrical bodies 1 are expanded, the gaps between each cylindrical body 1 are eliminated, the greenhouse H is kept in a substantially airtight state, and the warm air warmed by the incident light S is confined within the greenhouse H. Measure the temperature rise. During the daytime when the outside temperature is high, 1. The cylindrical body 1 is appropriately reduced to discharge a portion of the warm air inside the greenhouse H to the outside, thereby preventing the inside of the greenhouse H from becoming excessively high temperature. Then, at night when the outside temperature drops, the cylinder 1 is expanded and expanded again to keep the inside of the greenhouse H almost airtight.
Prevents warm air from escaping to the outside. At this time, the cylindrical body 1 blocks the flow of air inside and outside the greenhouse H, and the space 7 formed within the cylindrical body 1 forms a heat insulating layer, so that the temperature inside the greenhouse H is at the boundary with the outside air. It also prevents heat from being taken away through the cylindrical body 1.

It goes without saying that this response to the external environment by expanding and contracting the cylindrical body 1 is also effective against seasonal fluctuations.

In this way, the light amount and heat amount transmission amount adjusting device according to the present invention can prevent the indoor temperature from becoming excessively high by appropriately discharging indoor warm air to the outside while constantly letting in sunlight. If this device is used in a greenhouse, etc., the conditions within the greenhouse can be made optimal for the growth of plants. This temperature adjustment can be easily achieved by expanding and contracting the adjusting cylinder; when it is necessary to maintain or raise the indoor temperature, the adjusting cylinder is expanded, and when it is necessary to lower it, the adjusting cylinder is contracted. Since this can be achieved with just one step, it becomes possible to appropriately adjust the indoor temperature in response to changes in the external environment. Furthermore, the adjustment cylinder forms a heat insulating layer when expanding and expanding, and prevents the transfer of heat from indoors to outdoors, resulting in a significant reduction in fuel costs.
