Description

  The present invention relates to a meteorological observation pole and a method for standing a meteorological observation pole.

  Specifically, for example, the present invention relates to a meteorological observation pole for installing an anemometer or anemometer at a measurement point at a high place in a planned installation site of a wind power generation facility, and a method for standing a meteorological observation pole.

  In recent years, interest in environmental issues has increased, and the amount of installed wind power generation facilities has steadily increased.

  In the future, the installation amount of wind power generation equipment is expected to increase dramatically with the enhancement of related bills to promote the spread of new energy such as wind power generation.

  Furthermore, as a place to be installed, even in the case of Europe and the like, it may be constructed not only on land but also on the sea.

  However, wind power generation uses natural wind as its energy source, so even if a large amount of high-performance power generation equipment is installed, if it is installed in a place with poor wind conditions (wind speed and direction), sufficient generated power is generated. I can't get it.

  In addition, even if a sufficient amount of wind is blowing, installing a wind power generation facility in a location where the wind speed and direction change frequently will shorten the life of the facility or in the worst case. May lead to accidents such as equipment damage.

  Therefore, when the installation of wind power generation facilities is planned, for example, as shown in FIG. 12, a column (pole) having a height of about 30M or 40M to which a windmill type anemometer (anemometer and anemometer) is attached. Is built at the site where wind turbines for wind power generation are planned, and wind conditions (wind speed and wind direction) for selecting the wind turbine installation location are investigated by this wind turbine type wind direction anemometer.

  In the case of a 30M pole, an anemometer and an anemometer are attached to the ground heights of 20M and 30M, and in the case of a 40M pole, the ground height meters and anemometers are respectively attached to the ground heights of 30M and 40M.

  In other words, a pole (pole) with a height of about 30M to 40M is constructed at the wind turbine installation planned position, and fixed point observation is performed using a wind turbine type wind direction anemometer attached to the pole. Is regularly measured (for example, every week, every month, every year), and the data is tabulated to investigate the wind conditions at the planned construction site of the wind turbine for wind power generation.

  In this method, it is necessary to secure a large work site and set up the ground for installing the pole, and it is necessary to work at a high place in the installation work of the pole where the windmill type anemometer is installed, which requires a lot of labor and cost. There was such a problem.

  In addition, wind power generators are rapidly increasing in size, and currently 2000 KW is becoming standard, which corresponds to a hub height (rotor center of rotation) of about 70 to 80 m. Therefore, power generation companies have a strong desire to conduct wind observations near the height of the hub.

  In addition, the Agency for Natural Resources and Energy's outer organization, NEDO, has subsidized wind observations, up to 30 meters in height. It was changed from 40m to 50m from H17.

  As a conventional weather observation pole method, for example, there is a ginpole method that raises the entire weather observation pole by pulling the wire hung on the ginpole, but it requires a lot of land for installation work and compression when standing Because the pole cannot withstand the load, the height of about 60m was the limit.

  In addition, a truss system that assembles trusses locally is also adopted, but there is a problem that construction work becomes expensive because work at a high place is required.

  Therefore, it is a great advantage if a 100 m high weather observation pole can be easily set up on a relatively small land and at a relatively low cost.

  As means for solving the above-mentioned problems of the prior art, for example, in Japanese Patent Application Laid-Open No. 2004-101265 (Patent Document 1 below), on the ground surface that is a predetermined distance away from the position where the laser radar is installed. A step of obtaining altitude data and a point moved from a plurality of predetermined positions on the ground surface by a desired height as an observed point, position data in each polar coordinate system is calculated and calculated. Storing the position data, and setting the laser radar scanning method in advance so that the wind direction and wind speed of each observed point can be measured using the stored position data of each observed point. By automatically measuring the wind direction and wind speed at each observed point according to a preset laser radar scanning method, the data of a large number of observed points is automatically obtained using a laser radar. Wind measurement method of efficiently can be acquired for wind power windmill construction site it has been proposed.

  However, this patent document 1 provides a method for estimating the wind direction and the wind speed at the observation point based on the position data detected using the laser radar, and accurately determines the wind direction and the wind speed at the actual observation point. It was not possible to measure.

In addition, by using a Doppler soda (acoustic anemometer), it is possible to measure an altitude of several hundred meters from the ground, but this method is used only for special cases such as research purposes. This subsidy is only allowed for data from conventional mechanical (cup-type) anemometers.

  The best mode for carrying out the invention will be described in detail with reference to FIGS.

  1 to 3, 1 is a ginpole, 2 is a mast, 3 is a V frame, 4 is a first V frame, 5 is a second V frame, 6 is a first mast, and 7 is a second mast. Duplicated description is omitted by using the same reference numerals.

  FIG. 1 is a diagram illustrating a state before raising in a conventional weather observation pole of a ginpole type.

  As shown in FIG. 1, in the conventional method, the weight of the mast is lifted using a gin pole, but in order to suppress the occurrence of long column buckling due to the compressive force generated at that time, the wire rope M2A2 connected to the left and right anchors. Restraint was given by M2A4.

  FIG. 2 is a diagram illustrating a state in which the conventional ginpole-type weather observation pole is being raised.

  As shown in FIG. 2, when raising the mast 2, it is necessary to adjust the length of the branch line arranged in the horizontal direction. If the length adjustment of the branch line is not properly performed, It is very easy to cause a large bending deformation and breakage.

  FIG. 3 is a diagram illustrating a state in which the V frame type weather observation pole of the present invention is being raised.

  As shown in FIG. 3, instead of the conventional ginpole, by providing a V frame 3 that forms a V-shaped surface perpendicular to the mast 2 at the end of the mast 2 that stands up on the ground, Since the wire rope connecting the V frame 3 and the mast 2 can give not only the weight of the mast but also the horizontal force, it is not necessary to give the horizontal force restraint by the branch line of the ground anchor. Therefore, it is possible to rotate the observation tower about 90 degrees from the horizontal posture to the vertical posture without any adjustment work while relaxing the branch line from the anchor of A3 or A4. The raising work can be performed safely and reliably and quickly and easily.

  FIG. 4 is a diagram illustrating a state in which the weather observation pole having a plurality of masts according to the present invention is being raised.

  As shown in FIG. 4, the first mast 6 has a first V frame 4 that forms a V-shaped surface perpendicular to the first mast 6 at an end on the ground side, and the first mast 6 has a hinge box interposed therebetween. The second mast 7 connected to the second mast 7 has a second V frame 5 that forms a V-shaped surface perpendicular to the second mast 7 at the end of the second mast 7 hinge box. When assembling, the plurality of masts can be folded, so that the work space required for standing the weather observation pole can be reduced to about 1/4 of the conventional one.

  In the gin pole method, the height of the meteorological observation pole is limited in structural mechanics. However, according to the folding method of the present invention, the upper limit of the height can be greatly increased.

  5 and 6 are diagrams for explaining the tension of the branch line in the meteorological observation pole, and illustrate the balance of forces at the position M2 in FIGS. 1 to 4 in cross-sectional views.

  FIG. 5 shows the case of the conventional ginpole system, and FIG. 6 shows the case of the V frame system of the present invention. As shown in FIG. 6, in the case of the V frame system of the present invention, Even if a branch line is not used, a horizontal force can be applied to the mast, so that it is possible to prevent a long column buckling due to a compressive force when raising the mast.

  In the present invention, a folding weather observation pole can be realized by using a hinge box and a V frame, and as a result, an observation tower having a height of about 100 m can be built without requiring a job. Is possible.

  In addition, if this folding method is used for a land of a small area that could not be stood by the conventional ginpole method, it can be constructed.

  FIG. 7 to FIG. 12 show the procedure of the standing work of the meteorological observation pole of the present invention.

  FIG. 7 is a diagram illustrating the ground assembly process of the meteorological observation pole in the present invention.

  First, the first mast and the second mast are assembled on the ground in a folded state.

  Since the first mast and the second mast are assembled in a folded state, the work space corresponding to the entire length of the pole can be reduced to about ¼.

  As shown in FIG. 7, the first V frame 4 is attached to the end of the first mast on the ground side in a direction perpendicular to the first mast.

  The V frame is a frame that forms a V-shaped surface perpendicular to the mast at the end of the mast that stands up on the ground.

  A pulley is provided at the tip of the V frame, and the first mast 1 can be raised by raising and pulling the rope 1 on the pulley.

  In addition, wire ropes V12-M1, V12-M2, and V12-M3 are provided at three locations on the first mast. By connecting these three wire ropes to the pulley at the tip of the V frame, Since the tension generated in the wire rope when pulling up one mast can be divided into three, the bending moment acting on the first mast can be remarkably reduced, and the breakage and deformation of the first mast can be prevented.

  Further, since the second mast is connected to the first mast via the hinge box, the second mast can be pivoted with respect to the first mast around the hinge box. Is provided.

  The hinge box is a box installed on the upper part of the first mast, and has a long hole penetrating the rotation shaft provided at the end of the second mast so that the first mast and the second mast are relative to each other. And a member having a mechanism for causing the axes of the first mast and the second mast to coincide with each other.

  In the example of FIG. 7, the V frame is a frame arranged so as to form a V-shaped surface perpendicular to the mast, and a pulley is provided at the tip of the V frame, and the V frame is raised up. By attaching and pulling the rope 2 and the wire ropes V22-M4, V22-M5, V22-M6, the second mast can be turned with respect to the first mast.

  In the present invention, the material used for the mast and the V frame is not limited, but a steel pipe or a steel truss is preferable from the viewpoint of strength and workability.

  FIG. 8 is a diagram illustrating a step of erecting the first mast of the meteorological observation pole in the present invention.

  By pulling up the wire rope V22-M4, V22-M5, V22-M6 by changing the direction of tension by pulling up the raising rope 1 attached to the tip of the V-frame of the first mast from the ground with a winch or the like. The first mast can be raised as shown in FIG.

  FIG. 9 is a diagram illustrating a step of fixing the first mast of the weather observation pole in the present invention.

  By connecting the anchor on the ground and the three portions of the first mast with a guy rope, the first mast can be fixed in an upright state.

  FIG. 10 is a diagram illustrating a step of erecting the second mast of the meteorological observation pole in the present invention.

  As shown in FIG. 10, on the pulley provided at the tip of the V frame provided at the end of the second mast on the hinge box side, the raising rope 2 and the wire ropes V22-M4, V22-M5, V22-M6 are provided. The second mast can be swung around the hinge box to be raised by pulling it with a winch or the like installed on the ground to change the direction of the tension.

  FIG. 11 is a diagram illustrating a state where the second mast of the meteorological observation pole according to the present invention has been raised.

  In the state where the first mast and the second mast are folded, the central axis of the mast cannot be made coincident. However, by providing a guide groove made of an elongated hole that can move the rotating shaft in the hinge box, After raising the two masts, the central axis of the second mast can be shifted in the direction of the central axis of the first mast so that they coincide.

  FIG. 13 is a diagram for explaining the operation of the hinge box used in the present invention.

  As shown in FIG. 13 (a), the hinge box has a key-shaped long hole inclined with respect to the axis of the first mast in the plate fixed to the upper portion of the first mast. The rotating shaft provided at the end portion has a structure that penetrates the elongated hole.

  FIG. 13A shows a state in which the second mast is folded, and since the axes of the first mast and the second mast are displaced in the horizontal direction, the second mast can be folded without avoiding interference between the masts.

  As shown in FIG. 13 (b), in a state where the second mast is turned 90 degrees, the rotation axis of the second mast slides in the elongated hole and coincides with the axis of the first mast.

  Further, as shown in FIG. 13 (c), after turning the second mast to 135 degrees, it can finally be raised to the vertical position shown in FIG. 13 (d). Since the axes of the mast can be matched, the same strength as that of the integral mast can be obtained.
