Description

The present invention relates to an apparatus for preventing rainwater from flowing into a greenhouse. For example, when an opening is formed by rolling up a cover sheet of a greenhouse, rainwater is prevented from entering the greenhouse from the opening. This relates to a rainwater inflow prevention device for a greenhouse.

In the present invention, the “vinyl house” refers to a greenhouse formed by attaching a covering sheet to a support frame formed of a frame material such as a pipe.

In the present invention, the “coated sheet” refers to a coating sheet or film formed of a synthetic resin such as polyvinyl chloride.

It is necessary to form an opening in the greenhouse at high temperatures such as in summer.

When forming an opening in a greenhouse, the opening is generally formed by rolling up a part of a covering sheet in the greenhouse.

That is, as shown in FIG. 5, the opening 5 is formed by winding up the covering sheet 1 of the greenhouse by rotating the winding handle 3.

As shown in FIG. 5, the rainwater 6 that has fallen on the roof portion of the greenhouse flows down the both sides of the greenhouse through the covering sheet, and between the roll-shaped winding portion 1 a of the covering sheet 1 and the covering sheet 1. And then flows down into the greenhouse so as to be wound around the roll-shaped winding part 1a.

When rainwater flows into the planting floor near the opening 5 in the greenhouse, the floor soil becomes excessively humid, and the crops on the planting floor cause abnormal growth due to lack of oxygen, resulting in a significant reduction in productivity.

In order to prevent rainwater from entering the greenhouse through the opening of the greenhouse, the following method is generally used.

(I) Preventing rainwater from entering the greenhouse by closing the opening promptly at the start of rainfall.

However, in this method, when the worker is not in the vicinity of the greenhouse or when it begins to rain at midnight, the opening of the greenhouse cannot be closed in a timely manner. Rainwater will flow into the house.

(B) A net is stretched at the opening of the greenhouse.

However, in this method, although the amount of rainwater flowing into the greenhouse from the opening of the greenhouse is slightly reduced, the inflow of rainwater cannot be prevented.

(C) A roll-shaped covering sheet wound around the horizontal pipe is protruded from the opening by sandwiching an object between the horizontal pipe that winds the covering sheet of the greenhouse and the vertical pipe of the greenhouse. .

However, in this method, although a temporary effect can be seen in the case of light rain, it is not possible to prevent rainwater from flowing in in the case of normal rain.

Under such circumstances, Japanese Patent Application Laid-Open No. 2004-313142 proposes a rainwater collecting device for a greenhouse.

A greenhouse stormwater collecting apparatus (hereinafter referred to as “conventional greenhouse stormwater collecting apparatus”) disclosed in Japanese Patent Application Laid-Open No. 2004-313142 is provided with a clamping plate at each of the ends of a pair of clamping screws that support the water collecting basin. The drainage basin is attached to the greenhouse by fastening each fastening screw in a state where a pair of fastening plates are sandwiched between the structural pipes in the vertical direction via the covering sheet.

When a conventional rainwater collecting device for a greenhouse is attached above the opening in the greenhouse, it is possible to prevent rainwater from entering the greenhouse through the opening.
JP 2004-313142 A

However, in the conventional rainwater collecting apparatus for a greenhouse, there is a possibility that the covering sheet pressed against the surface of the structural pipe by the fastening plate may be damaged.

Moreover, in the said conventional greenhouse rainwater collecting apparatus, the operation | work which attaches a water collecting tank to a greenhouse is troublesome.

The present invention has been made in an attempt to provide a rainwater inflow preventing device for a greenhouse that does not have the above-described problems in the conventional rainwater collecting device for a greenhouse.

That is, the present invention provides an inexpensive rainwater inflow prevention device for a greenhouse that can be easily attached to a greenhouse without damaging the covering sheet and without preparing a mounting jig or the like. .

In order to solve the above problems, the present invention provides the following rainwater inflow prevention device for a greenhouse.
