Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rain cover apparatus for planting panels, which prevents rain water from flowing into a cultivation tank during rainfall in an outdoor hydroponic cultivation apparatus.

[0002]

2. Description of the Related Art Conventionally, it has been required to enhance the commercial value of plants by directly shining sunlight on the plants that have been hydroponically grown in the building. In order to meet the above requirements, when the conventional hydroponic cultivation apparatus in the building is directly installed in the open field, rainwater flows into the tank from between the planting panel and the side wall of the cultivation tank to dilute the culture solution during rainfall, Sometimes, the culture solution overflows to the outside of the tank, resulting in an uneconomical situation in which the culture solution having a required concentration must be repeatedly prepared and replaced.

In this case, if some kind of rainproof means for preventing the inflow of rainwater into the cultivation tank is adopted, the rainproof means is
It is desired that the plant has a structure capable of smoothly carrying out the immersion pest control method previously developed by the present inventor, in which a planting panel in which plants are planted is immersed in a culture solution for a required time.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention The inventions of claims 1 and 2 prevent the inflow of rainwater into the tank and prevent the planted panel from smoothly carrying out the immersion pest control method. An object is to provide a rain cover device.

As a means for solving the problem, the invention of claim 1 of the present application provides a base of a flat rainproof plate on a panel end side facing a side wall of the cultivation tank in the planting panel supported on the upper part of the cultivation tank with a gap. Connecting the ends, the rainproof plate, when the planting panel upper surface is located above the opening upper surface of the cultivation tank, slopes downward from the planting panel end side to a position that covers at least the cultivation tank side wall upper surface. With a length that extends with
When the planting panel is submerged in the cultivation tank, the rainproof plate base end is swingably connected so as to stand up along the inner surface of the cultivation tank side wall. Propose a cover device,

According to the second aspect of the present invention, the base end portion of the flexible rainproof sheet is connected to the panel end side which is supported on the upper part of the cultivation tank and faces the side wall of the cultivation tank facing the side wall of the cultivation tank. However, the rainproof sheet, when the planting panel upper surface is located above the opening upper surface of the cultivation tank, extending from the planting panel end side to the cultivation tank side wall upper surface with a downward slope,
And when the planting panel is submerged in a cultivation tank, it has a length to leave the sheet tip part on the upper surface of the cultivation tank side wall while being drawn into the tank along the inner surface of the cultivation tank side wall, the open field hydroponics We propose a rainproof cover device for planting panels.

On the other hand, in order to support the planting panel in a state where the upper surface thereof is located above the upper surface of the opening of the cultivation tank in the inventions of claims 1 and 2, the planting panel floats above the culture liquid surface. In the case of the type, the planting panel is made thick, and in the case of the type in which the planting panel is submerged in the culture solution by its own weight, the planting panel is hung so that it can be lifted and lowered from above. The former requires a high pressing force for the immersion of the planting panel in the execution of the immersion pest control, and the latter requires a large suspension device.

According to the invention of claim 3 of the present application, in addition to the problems of the inventions of claims 1 and 2, the planting panel is supported with a simple structure in a state in which its upper surface is located above the upper opening surface of the cultivation tank. An object of the present invention is to provide a rainproof cover device that can be used.

As a means for solving the problem, the invention of claim 3 is the invention of claim 1 in which the planting panel is cultivated with the rainproof plate extending downward from the edge of the planting panel onto the side wall of the culturing vessel. Provided is a rainproof cover device for a planting panel for outdoor hydroponics, which is provided with detachable locking means for locking the rainproof plate upwardly in a state of extension of the downward inclination so as to be supported on a side wall. To do. Embodiments of the present invention will be described below with reference to the drawings.

[0022]

According to the first and second aspects of the present invention, it is possible to prevent the inflow of rainwater into the tank by the rainproof plate or the rainproof sheet at the time of rainfall, whereby the conventional culture solution is added for each rainfall. It is possible to eliminate the drawback of mixing and replacing, and when performing immersion descent and raising of the planting panel in the practice of immersion pest control, the rainproof plate or rainproof sheet moves up and down along the inner surface of the side wall of the cultivation tank. In addition to the smooth dipping, the rainproof plate or the rainproof sheet can act as a protective wall surrounding the plant to prevent damage to the leaves of the plant when moving up and down.

According to the invention of claim 3 of the present application, in addition to the effects of the inventions of claims 1 and 2, only by placing the locked rainproof plate on the upper surface of the side wall of the cultivation tank, the upper surface of the planting panel can be changed. It can be supported in a state that it is located above the upper surface of the opening of the cultivation tank, so that if the planting panel is of float type, thin one, if it is a self-weight sinking type, without a suspension device, respectively. It became possible to set the rainproof plate to a downward slope that allows rainwater to flow.In the former case, it is easy to push down and settle the planting panel when performing immersion type pest control, and in the latter case a large suspension device is used. The advantage is that it can be omitted.
