BACKGROUND OF THE INVENTION
The present invention relates to an anti-freezing device for a surface such as a tee ground or green of a golf course.
[0002]
[Prior art]
In winter, the golf course teeing ground sometimes freezes, making it difficult to touch the teeing ground, and also freezing on the green, causing the ball to jump on the green and making the game less interesting.
[0003]
Therefore, the present invention provides an anti-freezing device in which a heater is set on a tee ground or green of a golf course to prevent freezing by warming the soil.
[0004]
[Means for Solving the Problems]
The present invention is characterized in that an electrically heated heating element for preventing the surface of the soil from freezing in the ground or the surface of a ground such as a tee ground or green of a golf course is embedded or placed.
[0005]
Thereby, the surface of the soil is heated to about 10 to 30 ° C., and the freezing of the surface of the soil is effectively prevented.
[0006]
Embodiment
Embodiments of the present invention will be described below with reference to the drawings.
[0007]
In FIG. 1, an anti-freezing device M of the present invention is buried at a depth of about 10 cm in the soil at a predetermined position of a tee ground G of a golf course. This anti-freezing device M has an electrically heated film heater 1, solar cells 2, 2... 2 are disposed in the vicinity of the four corners of the film heater 1. A tee 3 on which a ball 4B is placed is inserted.
[0008]
As shown in FIG. 2, the film heater 1 is formed by arranging strip-like heating elements 4, 4... 4 at predetermined intervals and laminating them with an insulating film. Electrodes 5 and 5 are attached, and solar cells 2, 2... 2 are connected to the electric wires.
[0009]
As shown in FIG. 3, a linear heating element 10 in which a heating material is vapor-deposited and bundled on a carbon fiber is laminated with an insulating film 30, and electrodes 11 and 11 are provided on both ends of the linear heating element 10. The solar cell 2 may be connected to the electrode 11. The belt-like heating element 4 and the linear heating element 10 are preferably elements disclosed in Japanese Patent Application No. 2003-148347. Alternatively, a heating element disclosed in Japanese Patent No. 2628519 may be used.
[0010]
That is, it is obtained by using at least tin oxide, lead oxide, and lead chloride as raw materials, adding a reducing agent to the raw materials and mixing to form a mixture, heating the mixture, and then cooling. A heat-generating functional material characterized by being produced from a supernatant or a precipitate is preferred.
[0011]
Note that the linear heating element 10 may be coated in a cylindrical shape with another coating material instead of the insulating film, and used in the form of an electric wire.
[0012]
As shown in FIG. 4, the solar cell 2 includes solar panels 20, 20,... 20 provided vertically in a case, and an electric double layer capacitor 21 set on the bottom of the case. The electric double layer capacitor 2 stores electricity and discharges little by little, and the film heater 1 generates heat even at night to prevent freezing.
[0013]
As shown in FIG. 5, a belt-like heater 22 is attached to the inner wall of the electric double layer capacitor 2, and the belt-like heater 22 has electrodes 24, 24 at both ends of the heating element 23 and is laminated with an insulating film. The electrode 24 is connected to the capacitor 21 and heated to prevent frost, snow, etc. from adhering to the transparent case portion 25 on the sunlight receiving surface.
[0014]
In the present embodiment, a solar battery is used as the heater power source, but the power source is not limited to this, and any power source within 3V to 280V may be used. It can be direct current or alternating current.
[0015]
By embedding a plurality of heaters 1 shown in FIG. 1 or the linear heating elements 10 shown in FIG. 3 over the entire surface of the green, it is possible to easily prevent the green from freezing. Note that the heater of the present invention is not limited to being buried in the soil, but may be placed on the upper surface of the tea ground or green.
[0016]
Further, as the heating element, a semiconductor electrothermal conversion material disclosed in Japanese Patent No. 2628519 can be used.
[0017]
That is, at least one chloride selected from tin tetrachloride and antimony trichloride, lead chloride, zinc chloride and indium chloride is dissolved in one organic solvent selected from ethyl alcohol, methyl alcohol and acetone. One solution selected from aqueous solutions of ammonium fluoride, hydrofluoric acid and tartaric acid is added to the solution for reduction, and this is heated to 150 to 250 ° C. to form a binder (such as Teflon (registered trademark)). It is also possible to use those formed into a film form by vapor deposition) or those deposited and deposited.
[0018]
【The invention's effect】
Since this invention was comprised as mentioned above, the freezing of the tee ground or green of a golf course can be prevented effectively.
