The present invention relates to an instrument freeze prevention device in which one end of a heat pipe is buried underground and the other end of a heat pipe is arranged in parallel with a pressure impulse pipe in contact with the other end.

The above-mentioned instrument antifreeze device conventionally utilizes geothermal heat to prevent freezing of instruments in which internal liquid hardly flows like liquid transport pipes, by bringing the heat dissipation part of the heat pipe into contact with the impulse pipe. It was known that the heat absorbing part was simply buried underground at a depth of 2 to 5 m.

しかし、冬期の寒冷時には地表面近傍の地中部

できなかつた。(For example, Japanese Patent Application Laid-open No. 58-58414) [Problem that the invention attempts to solve] However, during cold winters, the underground part near the earth's surface becomes very cold, and the geothermal heat absorbed in the deep underground part is absorbed by the earth. Because the heat is radiated and lost in the underground near the surface, it could not be efficiently transmitted to the impulse pipes above ground.
また液輸送管が有する熱も充分には利用されて
いなかつた。 Furthermore, the heat possessed by the liquid transport pipe has not been fully utilized.
本考案の目的は、深い地中部で吸収した地熱を

The characteristic configuration of the instrument freeze prevention device of this invention is that the heat pipe is located 50 to 75 cm near the ground surface in the underground part.
is surrounded by a heat insulating material that prevents heat radiation from inside the heat pipe to the underground part, and the ground surface is surrounded by a heat insulating material that prevents heat exchange between the heat pipe and the outside air, and the thickness of the heat insulating material in the radial direction of the heat pipe is The thickness is made larger than the thickness of the heat insulating material, and the tip of the other end is disposed within the heat insulating material near the protrusion for deriving static pressure. It is as follows.

In other words, by surrounding the surface side of the underground part of the heat pipe with heat insulating material, the geothermal heat absorbed deep underground is less likely to be radiated on the surface side even in cold weather, reducing heat loss and transferring it to the surface. It can be efficiently transmitted to the impulse pipe. At that time, we focused on the fact that the heat capacity of air is smaller than that of soil, so especially in the early morning hours when freezing occurs, the parts of the earth that are close to the surface of the earth are likely to get cold. In addition to increasing the effectiveness, the thickness of the insulation material at the ground surface can be made thinner, thereby achieving an economical effect of reducing the amount of insulation material required. Furthermore, since the thickness of the heat insulating material is large, even if a bending force is applied to the heat pipe, the thickness of the heat insulating material absorbs the force, making it possible to achieve the effect that it will not easily bend. .

有効に地熱を伝達することができる。 With the above configuration, it is possible to ensure heat retention of the part on the ground side in the underground part, and also to provide sufficient heat insulation by providing the tip of the other end of the heat pipe close to the liquid transport pipe. Therefore, the heat held by the liquid transport pipe, which is maintained at a temperature that does not allow freezing, and the fluid (technical water) flowing inside this pipe, is effectively used to prevent the impulse pipe from freezing, and the heat pipe can prevent freezing. up to the highly sensitive impulse pipe parts.
Geothermal heat can be transferred effectively.
従つて、計器の凍結防止に地熱を十分利用でき

Therefore, it is possible to provide an economical and efficient device that can sufficiently utilize geothermal heat to prevent freezing of instruments.

凍結防止装置を形成してある。 A gauge 3 such as a pressure gauge or a flow meter supported by a column 5 is connected to the liquid transport pipe 2 covered with a heat insulating material 7 at an intermediate portion in the longitudinal direction across a pressure impulse pipe 4. Compared to the liquid transport pipe 2, the internal liquid hardly flows, so the impulse pipe 4 is prone to freezing during cold winters, and one end of the impulse pipe 4 is about 2.
The other end portions 1b of the heat pipes 1 buried at a depth of ~5 m are arranged side by side in contact with each other, and a heat insulating material 8 made of glass wool is coated on the outside to form an instrument antifreeze device.

つてより効率良く地熱を地上に輸送できる。 The surface side of the underground portion 1a of the heat pipe 1 (approximately 50 cm to 75 cm deep) is surrounded by a heat insulating material 9 made of glass wool to prevent heat radiation near the surface during cold weather. In addition, since air has a smaller heat capacity than soil, we focused on the fact that the parts underground and close to the surface of the earth are likely to get cold, especially in the early morning hours when it is easy to freeze. The thickness of the heat insulating material 9 is configured to be larger than the thickness of the heat insulating material 8. Therefore, when not insulated, the amount of heat released is 4 to 6 times as much as when insulated, and by insulating, geothermal heat can be transported to the ground more efficiently.
