The present invention relates to an anemometer, and more particularly, to a wind power meter using a streamlined mechanism that can be installed by a small number of people anemometer and wind vane at a point where the crane can not enter by using a streamlined mechanism.

Currently, fossil fuels such as petroleum, coal, and natural gas, which are generally used all over the world, are not exhausted due to the limitations of underground resources, and due to the waste gases such as carbon monoxide and nitrogen oxides generated during combustion, As the main culprit of destroying the natural environment by causing destruction and global warming, it is permanently available as an alternative to it, and much attention is paid to wind power generation, which is one of the most advantageous renewable energy technically and economically without polluting the environment. ought.

Therefore, in the same vein, following the advanced countries such as Europe and the United States, the wind power generation project and the construction of wind farms have been actively promoted in Korea.

However, the construction of wind farms that produce wind energy should be preceded by a survey of the basic location of wind resources.

To this end, roads where cranes can enter must be constructed in advance and the cranes must be arranged. Wind speed is measured by measuring instruments in areas where crane entry is difficult, and uniformity of wind speed, wind direction, and turbulence are required for the construction of wind farms. If the road does not meet the standards, the economic losses incurred in investment in road construction, equipment transportation and installation work cannot be avoided.

In order to solve this problem, excellent technology such as "Anemometer using ad balloon" of Korean Patent Publication No. 2002-23769 has been published, but the mechanism is shaken when the wind speed and the wind direction change due to the mechanism such as a ball that is heavily influenced by the wind. As the anemometer shakes up, down, left, and right, it is expected that a problem that a lot of measurement errors occur.

Accordingly, an object of the present invention is to provide a wind turbine for wind power generation using a streamlined mechanism that can be easily and quickly installed by a few manpower by using a streamlined mechanism at a point where the crane cannot enter. There is.

Another object of the present invention is to prevent the horizontal and vertical shaking of the anemometer due to the various horizontal stabilization means of the anemometer and wind vane installed wind turbine for wind power generation using a streamlined mechanism that can increase the reliability To provide.

In addition, by installing a disc-shaped horizontal safety plate 80 in the main rope 30 to further suppress the main rope 30 to move in the vertical direction, it is most preferably installed in the space between the wind gauge support member 40 Do.

Since the main rope 30 and the auxiliary rope 60 have to be lifted up to the air by the mechanism 10 and must be solid, it is preferable to use a light and tensile nylon or piano wire or aramid fiber material.

Consists of a plurality of support lines 47 for holding and fixed at a predetermined position of the main rope (30).

The apparatus 10 is designed to be streamlined, but designed such that the upper surface length A2 is longer than the lower surface length A1 based on the center rim H, that is, the upper surface area is larger than the lower surface area. Thus, as the wind gets stronger, it is better to receive a larger lift in the upward direction and receive a smaller wind resistance, and the elastic member 20 has the force in the vertical direction due to the change in the lift of the mechanism 10 when the wind speed suddenly changes. Can be absorbed, and even if the main rope 30 is shaken from side to side, the horizontal member 41 is suspended by the fastening means 45, such as a ring, so that the anemometer 50 and the wind vane 55 always remain horizontal. Done.

By analyzing the, the model of the wind turbine, the size of the wind farm will be determined.

2 is a circuit block diagram illustrating a signal processing circuit of an anemometer applied to the present invention, and includes a wind detection device 530 and a wind measurement device 550.

First, the wind detection device 530 is installed on the wind gauge support member 40 is configured to detect the wind speed according to the rotation of the wind cup 510, and to output the corresponding signal by wireless or wired, wind measurement device 550 is provided on the ground to receive the wind speed-related signal transmitted from the wind power detection device 530 by wireless or wired to store the predetermined wind speed data and periodically corresponding to the wind speed information through a predetermined wired / wireless network It is configured to transmit to the main monitoring system 100.

That is, the rotating shaft 512 is vertically fixed to the central portion of the wind cup 510 installed in the wind gauge support member 40, and the hole circle plate formed with a plurality of through holes 516 at regular intervals at the lower end of the rotating shaft 512. 514 is installed and configured to rotate in conjunction with the wind cup 510, and the light emitting diode 531 and the light receiving transistor 533 are disposed on the upper and lower sides of the hole disc 514 so as to face each other at a predetermined interval. The beam 531 is configured to be transmitted to the light receiving transistor 533 through the through hole 516 of the hole circle plate 514.

The reference voltage Vref set by the variable resistor VR is output at the output terminal of the light receiving transistor 533 which is turned on only when the beam emitted from the light emitting diode 531 is transmitted to the light receiving transistor 533. A comparator 535 for outputting a pulse according to the result is compared with the result, and a waveform shaping circuit unit 537 for converting and outputting a pulse into a stable waveform is connected to an output terminal of the comparator 535. The output terminal of the circuit portion 537 is connected to a first amplifier 539 for amplifying the shaped pulse to a predetermined level.

In addition, the wind measuring device 550 installed on the ground includes a second amplifying unit 551 and a second amplifying unit 551 for secondarily amplifying a signal transmitted from the first amplifying unit 539 to a predetermined level. A / D converter 553 for converting the analog signal of the pulse form output from the digital signal to the output and the data output from the A / D converter 553 receives the data to analyze the wind speed and wind direction data to the internal memory After storing, the control unit 555 periodically transmits wind speed information and ID to the main monitoring system 100 through a wired or wireless network by using a predetermined wired / wireless communication modem 557.

The main monitoring system 100 is a computer for displaying the wind speed as a numerical value on the screen by a program set up by analyzing and decoding each.

In addition, the wind detection device 530 installed on the wind gauge support member 40 and the wind measurement device 550 installed on the ground may be configured to receive driving power from the solar cell 90 installed on the ground, respectively.

On the other hand, although the wind detection device 530 and the wind measurement device 550 has been described as transmitting data in a wired manner, the wireless transmission means and the receiving means to the wind detection device 530 and the wind measurement device 550 respectively. In addition, it is obvious that the wind speed and wind direction measurement data can be configured to be transmitted wirelessly.

Referring to the installation process of the anemometer using the mechanism according to the present invention made as described above are as follows.

First, as shown in FIG. 1, after the hole 43 is drilled in the center of the anemometer support member 40, the anemometer including the wind detectors 510 and 530 of FIG. 2 at the edge of the anemometer support member 40 ( 50) and the wind vane 55 are installed, and fastening means 45 such as at least two or more rings are installed around the hole 43 so that the center of gravity is matched. Subsequently, after inserting and fastening the main rope 30 through the hole of the anemometer support member 40, the support line 47 is attached to the ring, which is the fastening means 45, and then the sub-connection ring 31 of the main rope 30. Tie the support string 47 to install the wind gauge support member 40 to the main rope (30).

On the other hand, the horizontal safety plate 80 is inserted between each of the wind gauge support members 40 and fastened to the main rope 30 using a predetermined ring and a support line.

In this manner, the plurality of wind gauge support members 40 and the horizontal safety plate 80 are installed on the main ropes 30 at regular vertical intervals, respectively.

In addition, after the main rope 30 and the plurality of auxiliary ropes 60 are fixedly installed on the ground support block, the main connecting ring 25 is fastened to the main rope 30 and the auxiliary ropes 60, and then the main connecting ring. The spring 20 and the emergency rope 70 are respectively installed on the 25, and the spring 20 and the emergency rope 70 are fastened to the mechanism connecting ring 15 again, and then a support line connected to the apparatus 10 ( 11) to the instrument connecting ring (15). Then, when the main rope 30 is slowly released, the device 10 is supported by the helium gas filled in the device 10 and ascended up to the air by the length of the main rope 30, thereby completing the installation.

In addition, at least two auxiliary ropes 60 are used. The shape of the auxiliary ropes 60 is approximately equilateral with the shape of an isosceles triangle, the shape of a triangular pyramid, or the shape of a pyramid. In addition, by connecting a turnbuckle (not shown) in the middle of the auxiliary rope 60, it can be arbitrarily adjusted to a suitable tension.

When the installation of the anemometer 50 using the mechanism 10 according to the present invention as described above is completed by the operating power output from the solar cell 90 shown in FIG. 550) is supplied with power and becomes operable, and the system must be driven by adding a charger and a storage battery as well as a solar cell in preparation for a rainy season or a cloudy day.

As such, when air flows in the vicinity of the wind turbine support member 40, which is raised from the ground to a certain height by the mechanism 10, the wind cup 510 is rotated as the air pressure acts on the wind cup 510. When the wind cup 510 is rotated, the hole circle plate 514 connected to the rotating shaft 512 is interlocked to rotate.

At this time, the beam of the light emitting diode 531 as the photodiode passes through the through hole 516 formed in the hole circle plate 514 and is transmitted to the light receiving transistor 533 as the phototransistor, thereby turning on the through hole 516. If not, the beam is blocked by the hole source plate 514 to turn off the light receiving transistor 533. That is, when the beam of the light emitting diode 531 is transmitted to the light receiving transistor 533, the light receiving transistor 533 is turned on to output a signal, and the beam of the light emitting diode 531 is transmitted to the light receiving transistor 533. If not, the light receiving transistor 533 is turned off and there is no output.

As the signal output due to the turn-on state of the light emitting diode 531 is applied to the non-inverting terminal (+) of the comparator 535, the comparator 535 is set by the variable resistor VR to invert the terminal (-). The voltage of the light emitting diode 531 applied to the non-inverting terminal (+) is higher than the reference voltage Vref and outputs a 'high' signal.

On the contrary, when the light receiving transistor 533 is turned off and there is no output signal, no voltage is applied to the non-inverting terminal (+) of the comparator 535, which causes the non-inverting terminal (+) of the comparator 535 to become negative. As the applied voltage is lower than the reference voltage Vref, the 'low' signal is output, so that the comparator 535 outputs a pulse type signal proportional to the wind speed according to the on / off state of the light receiving transistor 533.

The wind speed signal in the form of pulses output from the comparator 535 is converted into a stable pulse waveform by passing through the waveform shaping circuit unit 537, and the wind signal in the form of a shaped pulse is applied to the first amplifier 539. Amplified to a predetermined level is transmitted to the wind measuring device 550 installed on the ground.

The wind measuring device 550 receives the data transmitted from the first amplifier 539 through the wire installed in the main rope 30, amplifies the data again to a predetermined level, and then amplifies it to a predetermined level. The A / D converter 553 is input to convert the digital signal, and the wind speed data converted into the digital signal is input to the controller 555. The controller 555 calculates the wind speed by analyzing the input data. After storing in the memory, the wind speed-related information is transmitted to the main monitoring system 100 through the communication modem 557 and a predetermined wired / wireless network at regular intervals, and the main monitoring system 100 transmits the wind speed-related information. Will be displayed or displayed on the screen.

Therefore, in the present invention, if you want to install the wind gauge for the construction feasibility of the wind farm in the remote islands or mountainous regions where the crane cannot enter, the wind gauge can be easily installed using a streamlined mechanism. In addition, horizontal stabilization means such as streamlined mechanisms, springs, and horizontal safety plates prevent shaking of the anemometer and wind vane, enabling precise measurement, and eliminating the need for road construction, tree removal, and crane arrangement for entry of wind gauges. In addition to the cost savings, there is an excellent advantage to prevent the destruction of the environment.
