The present invention relates to a ceiling window opening and closing device for a greenhouse, and more particularly, in a summer or winter, a greenhouse ceiling opening and closing that can promote the growth of cultivated plants by adjusting the temperature inside the greenhouse to be suitable for growing conditions of horticultural plants. Relates to a device.

In general, the greenhouse is divided into a tunnel type single-acting type with one roof and interlocking type by connecting several roofs together.

Single-acting greenhouse, as shown in Figure 1, providing a plurality of double arc-shaped frame 101 and interconnected the ends of them to create a single unit domed frame. After arranging a plurality of the domed frames at regular intervals along the longitudinal direction to form a greenhouse 100 having a tunnel shape, it is completed by covering the outer surface with vinyl.

The temperature inside the greenhouse is an important environmental factor for the growth of cultivated horticultural plants, and the temperature inside the greenhouse should be kept constant even during seasonal changes.

In other words, in a season when the temperature increases, such as summer, the temperature inside the greenhouse is rapidly increased, so that the plant cannot grow and die out (hereinafter referred to as "drying phenomenon"), which is too high than the air temperature.

In the season when the temperature is lowered, such as winter, the temperature inside the greenhouse is rapidly lowered, causing the plant to freeze (hereinafter referred to as "low temperature phenomenon").

Accordingly, in order to prevent the drying phenomenon of the plant due to the high temperature, water sprayed by spraying water on the outer surface of the greenhouse by providing a sprinkler 102 on the outer upper surface of the greenhouse 100 as shown in FIG. Along the outer surface of the greenhouse is adopted to lower the temperature inside the greenhouse.

However, the temperature reduction method of the greenhouse using the sprinkler 102, the water flowing down the outer surface of the greenhouse 100 can see the effect of the inner region of the greenhouse forming a boundary of the greenhouse to some extent, but actually lowering the temperature There was a problem that the temperature does not uniformly down to the inner central portion of the greenhouse 100, which is a zone where plants are needed to grow.

Therefore, there is a problem in that the income of the horticultural plants grown in the greenhouse 100 causes enormous obstacles, as well as a decrease in yield accordingly.

In addition to the problems described above, the conventional method for controlling the temperature inside the greenhouse using a sprinkler is because the water sprayed from the sprinkler continuously flows down the outer surface of the greenhouse, causing a significant temperature difference inside and outside the greenhouse. Dew condensation occurred, resulting in a decrease in the amount of sunlight transmitted and consequently a huge obstacle to the growth of horticultural plants.

In addition, in the conventional method of controlling the temperature inside the greenhouse, since the water sprayed from the sprinkler flows down the vinyl on the outer surface of the greenhouse and seeps into the ground, the ground of the area always has excessive moisture, There was a problem that the horticultural plants do not grow normally due to adverse effects on the plants located.

In addition, conventionally by providing a separate heating means in the greenhouse to prevent the low temperature of the plant to supply a high temperature hot air to the inside of the greenhouse to supply the hot air circulating the inside of the greenhouse to increase the temperature inside the greenhouse The method is adopted.

However, the method of increasing the temperature of the greenhouse using the heating means may increase the temperature evenly to the inner central part of the greenhouse, which is a region in which plants which need to increase the temperature may be effective in the vicinity of the heating means. There was a problem that can not be.

In order to solve this problem, when the temperature of the hot air generated by the heating means is raised so that the temperature of the central portion may be increased, there is a problem that drying occurs in the plant close to the heating means.

Therefore, there is a problem that the income is lowered due to the reduction in yield as well as causing a huge obstacle to the growth of the horticultural plants grown in the greenhouse.

On the other hand, conventionally, as shown in Figure 3 installed on the upper side of the greenhouse so as to open and close to illuminate the inside of the greenhouse.

When the moving pipe 210 is moved, the moving wire 211 is moved together to rotate the first rotating roller 202, and the lifting wire 201 moves together as the first rotating roller 202 is rotated. While the window wire 200 is connected to the lifting wire 201 is moved downwards, the other end of the lifting wire 201 is wound on the second rotating roller 203, so that it maintains a constant elasticity It is rotated to a state.

On the other hand, when closing the ceiling window opened through the above process, if the drive motor 220 is operated in the reverse direction by the rotational force generated in the drive motor 220 is the belt 221 and the moving pipe 210 in the reverse direction The moving wire 211 and the lifting wire 201 connected to the moving pipe 210 are moved in the reverse direction and are closed while moving the window frame 200 upward.

However, such a conventional device is to open and close the window frame 220 after the rotational force generated from the drive motor 220 is transmitted to the rotating roller and the wire, when the foreign matter flows into the contact surface of the rotating roller and the wire or the humidity is high Due to the rotational force of the roller, the wire is not moved smoothly, there is a problem that can not open and close the ceiling window.

In addition, since the wire is stretched during long-term use, there is a problem that a slip phenomenon occurs due to a decrease in the elastic force of the wire.

In addition, the conventional window frame is opened and closed in a sliding manner in the upper part of the greenhouse, when the wire is broken, the window frame 200 falls and damages the surrounding equipment, and in severe cases, there is a problem that a human injury occurs.

In addition, the conventional window frame is installed so as to maintain a predetermined inclination angle, the center of gravity is located smoothly when the bottom is located in the sliding manner open, but when closing the open window frame due to the high weight window frame There was a problem that an overload occurs in the composition motor.
