Description

The present invention relates to a switchgear for a covering material capable of placing a subject and taking a picture.

In institutional horticulture, energy-saving and de-oiling measures to reduce the amount of fuel used for heating to maintain the temperature in winter cultivation are extremely important. In order to reduce the amount of heating fuel used, it is basic to suppress the heating load by improving the heat retention performance of the pipe house, and for that purpose, it is effective to use a covering material having high heat insulating properties. So far, it has been clarified that the multi-layer heat insulating coating material (futon material) has higher heat insulating performance than the conventional heat insulating covering material and is effective in improving the heat insulating performance of the house.
However, the futon material is thicker than the conventional heat insulating coating material, and the convergence when it is opened by the winding method or the curtain method during the day is inferior. And the solution is required. In addition, when installing not only futon materials but also covering materials for lining in a house, there are many methods of opening and closing using materials divided into multiple sheets, and there are many gaps that occur at the joints when expanding. It is a cause of lowering the heat retention.
Commonly used opening and closing methods include a curtain method that slides on a skeleton or wire to open and close, and a method that creates a lining skeleton with an inclined roof surface and opens and closes on the lining skeleton by a winding method. In both cases, pipes or wires are used for the lining frame, and they are installed using the shoulders of the house. Therefore, in the non-stretched state of the covering material, the covering material is converged on the ceiling portion or the shoulder portion, and the converged covering material shields the solar radiation. In addition, it is necessary to open and close by using a plurality of covering materials, and a gap is likely to be formed at the joint, which is a factor of lowering the heat retention property at the time of heating.
Patent Document 1 is a method of opening and closing the outer lining for tunnel ventilation, and a rotating shaft and an arm are used for the opening and closing method.
Patent Document 2 is an opening / closing method for ventilating the outer lining of a house, and is composed of a rotating shaft and an arm as in Patent Document 1.
Patent Document 3 is a method of opening and closing a suspended curtain in the depth direction of a house, and can suppress a decrease in the amount of solar radiation when the curtain is opened.
Patent Document 4 improves the heat retention of a house by using a covering material for a double-structured lining that forms an air layer, and spreads the house while blowing air with a blower to open and close the house. This is a method (curtain method) in which the material is pulled up by stopping and rotating the wire drum.
In Patent Document 5, a guide wire rod (cable) is stretched, a guide roller is inserted and supported in the guide wire rod, and the guide wire rod is self-propelled along the guide wire rod.

However, Patent Document 1 and Patent Document 2 cannot be used for opening and closing the lining in a house which is a large structure.
Further, in Patent Document 3, in the case of a house having a long depth, the converging portion of the curtain is the end face portion, and a large converging space is required.
