DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for controlling the defrosting of cherries in a shelter house.

[0002]

2. Description of the Related Art In this type of conventional apparatus for preventing frost damage, it is assumed that the cause of frost damage is that nighttime cold air stagnates near the ground surface. For this reason, a concrete or steel pole about 8m high is erected separately from the house, and a fan is attached to the tip to prevent frost and frost by causing convection between the warm air above and the cool air below. Was. However, this equipment requires specialized skills and large equipment costs in construction, and since the concrete columns and metal columns are installed by basic concrete which is an electrical insulator, it is necessary to provide a lightning arrester for each, In addition, it was impossible to remove the pillars or remove the Juan, leaving him exposed to the elements of the wind, which required a great deal of maintenance to maintain Juan's swing mechanism and other functions. In addition, the temperature of the ground surface suddenly dropped due to the radiation cooling phenomenon at night, and there was an adverse effect such as frost blight on young fruit trees.

SUMMARY OF THE INVENTION The present invention relates to an apparatus for preventing frost damage on cherries on a rain-protection house, using a height of a steel frame, and removing a fan at the top of the house. By arranging them freely, the conventional construction columns are eliminated, and the danger of lightning is grounded using good conductors of the house reinforcement.

[Means for Solving the Problems] Generally, in a house for cherries, a vinyl sheet is prepared before the harvest season as a result of a flower, and a sheet for which a rain forecast is given by a weather forecast is put on and a fruit hits the rain. It is common to prevent this. This is to prevent the rainfall during the harvest season from causing actual cracks and losing commercial value.

[0005] In the present invention, in the frost prevention management device from late April to mid-May when late frost occurs, that is, from the opening stage of the cherry to the end stage, a house (steel frame only) which is not usually covered with a sheet is used. Therefore, in the present invention, in the present invention, the fan shaft is detachably mounted on the house steel ridge upward or downward so as to be detachable, and by turning the fan downward, air near the ground surface is reduced. In addition to stirring to increase the temperature, a sprinkler is provided on the ground to continue watering so as not to lower the temperature of the ground surface to 0 ° C or less.

[0006]

The weather conditions that cause frost damage occur when the ground cools due to radiant cooling and the temperature of the atmosphere rises above the surface temperature. Therefore, this can be prevented if the surface temperature can be maintained at 0 ° C. or higher.

According to the past meteorological data, when the surface temperature at the time of frost generation was -3.degree. C., the temperature of the atmosphere at a height of 8 m was + 3.degree. The present invention provides such cherries by mounting a fan on a house to agitate the atmosphere to raise the atmospheric temperature near the surface of the ground and to prevent the temperature of the surface from falling below 0 ° C. by sprinkling water on the ground. It can prevent frost and frost damage.

Further, at the time of harvesting, since the roof surface is closed to prevent rain, the temperature rises, and high-temperature damage (rots after the harvest) often occurs on the fruits. Further, the working environment in the house deteriorates. In this environment, the work of Juan can be easily exchanged with the outside air, and the work of moving vinyl on the roof can be completely excluded.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an embodiment of a frost prevention management system for cherries according to the present invention. FIG. 1 is a diagram showing an embodiment of claim 1. FIG. FIG. 3 shows an embodiment of the sprinkler.

In the figure, (1) shows a reinforcing bar of a house for cultivating cherries, and (4) and (5) show pipes on the top of the house. Reference numeral (3) denotes a metal shaft for mounting the fan (2), and a power supply for driving the fan (3) is built in the shaft (not shown). Reference numeral (6) indicates a sprinkler. Therefore, FIG.
Where Juan (3) is a pipe at the top of the house (4),
The shaft (2) is mounted upward on the ridge shown in (5), and the fan (3) is installed so as to pivot downward. The atmosphere is stirred from above the house (1).

The embodiment shown in FIG. 2 is different from the embodiment shown in FIG. 1 in that a metal shaft (2) is attached to a pipe (4) at the top of the house with the metal shaft (2) facing downward. ) To stir the air in the house (1).

Further, in the embodiment of FIG. 3, in addition to the embodiment shown in FIGS. 1 and 2, a sprinkler (6) is provided on the ground to sprinkle water on the ground surface. It prevents the surface temperature from dropping below 0 ° C. In the figure, the embodiment in which the fan (3) is separately mounted on the upper and lower sides is shown.

[0013]

According to the present invention, a fan is provided on a steel-frame-only house building on which a sheet is not yet covered at a time when late frost is likely to occur, and a warm air above and a cold air stagnating below are stirred. The temperature of the air near the ground surface is raised to prevent frost damage, and the installation and removal of the fan can be easily performed to facilitate maintenance and inspection of the equipment. There is no danger of lightning. Sprinklers are installed on the surface of the ground to prevent water from falling below 0 ° C, which is extremely effective in preventing frost damage on cherries. Not only can it be used effectively to protect cherries, but it can be installed economically and used for multiple purposes.
