Description

{Meteorological Mast} An eclipse measurement tower that is easy to construct and safe for lightning.

The present invention relates to a bulb-measuring tower installed to measure a condition of a bulb height (wind velocity, wind direction, atmospheric pressure, temperature, etc.) of a hub at the time of installing a wind turbine,

More specifically, the present invention relates to a data collecting device installed in a tower and a wind measurement tower that minimizes the damage to the sense by minimizing the possibility of installation of a lightning strike to the tower side.

In general, the Meteorological Mast (MM) is installed to accurately measure and reflect the wind-turbine condition of the wind turbine as the wind direction changes according to the difference in temperature or pressure.

An upright tower having a height of approximately 50 to 80 m is installed and a temperature sensor, an anemometer, a vane, or the like is installed on a side boom protruding from the top of the tower or horizontally, , Wind direction, and atmospheric pressure.

At this time, the measured information is transmitted to the data collection device installed in the lower part of the tower and reflected in the movement of the wind turbine.

The Meteorological Mast is installed in a high mountain area with no wind turbines,

Especially at this time, it was difficult to transport the bulky and heavy towers and the materials for constructing them to the high mountains.

Moreover, even if these towers and materials are transported to a high mountain area, it is difficult to construct them upright in a windy area. Such a bullwhip measuring tower is made of a metal material, so that it is inevitably subject to much damage caused by a lightning stroke.

Therefore, in order to prevent such damage, a method has been devised in which a lightning rod is installed at the upper end, a grounding facility is formed at the lower end, and a tower is made to flow to the ground as a conductor when a thunderstorm occurs.

However, this facility was not to avoid lightning, but rather to increase the damage by guiding the lightning to the tower, which does not need to be unnecessarily hit.

In other words, the tower would attract a lightning strike with a positive charge to a site with a negative charge,

At this time, the induction lightning current flows into the earth and the ground wire, and the internal voltage rises, causing the electromagnetic sensor to instantly damage or damage the sensor and the data collecting device installed in the tower.

Therefore, according to the present invention, a tower and a ground are insulated from each other, and a lightning strike having a positive charge and a ground having a negative charge are separated from each other,

Thereby minimizing damage to the data collection device and sense by making it unnecessary to induce the lightning strike toward the tower,

In addition, there is no need to transport unnecessarily large amounts of material to the mountainous area, and the towers can be installed easily with sufficient pulling force.

To this end, in the present invention, one or more side booms are formed on the left and right sides, and the sensors for measuring the condition of the atmospheric condition are installed in the side boom, and a data collecting device In the enrichment measuring tower installed,

The bulb-measuring tower includes a plurality of vertically erected support posts, a connecting rod connecting the support posts, a support piece protruding outwardly from the support upper end, and a fixing hole formed at an upper end of the support member A plurality of connection towers in which fixed flanges are formed integrally are formed, and these are connected in series to form an upwind measuring tower erected up and down.

According to the present invention, a lower pedestal is fixed by a ground anchor having a thread formed at a rear end thereof in a state where the lower plate and the insulating plate are overlapped,

When the tower plate is placed on the insulating plate, the insulating washer is fitted to the rear end of the ground anchor exposed on the through hole, and the through hole of the tower plate is fastened with a very high fixing nut, To minimize the possibility that the lightning strike will be directed toward the tower.

In addition, the present invention is characterized in that a frame end extending outwardly from the support is integrally formed with the connecting rod, and in particular, a fixing piece protruding upward and downward along the support is formed at the edge of each support, So that the ground and the tower are separated from each other because the ground wires including the insulating stick are connected to the fixed base installed on the ground in a state in which the ground wires are strapped.

In addition, the present invention provides a method of forming a buried space by advancing a trench in a depth of 1.2 to 1.5 m underground, forming a plurality of buried holes perforated in the lower end of the buried space at a depth of 1.2 to 1.5 m,

The anchor plate having a lot formed thereon is positioned after inserting a depth anchor having a screw thread at the rear end thereof, and a rear end of the depth anchor exposed at the hole of the anchor plate is fastened with a joint bolt , The buried space is filled with soil and cement so that only the upper connecting portion of the lot is exposed, so that the tower can be easily installed with sufficient pulling force.

The present invention minimizes the probability of failure of the data collection device and sense while reducing the likelihood of being hit by a lightning strike by insulating the tower from the ground.

Further, the present invention enables the towers to be easily installed while having a sufficient pulling force in the high mountains.
