Description

  The present invention relates to an illumination display tower and a vertical axis windmill, and more particularly, a display body and a strong vertical axis windmill supported by a support frame, and the display body illuminated by the power generated by the windmill and the vertical axis. Regarding windmills.

Conventionally, a display tower is provided with a display board on the tower, and illumination light from external electric power is applied to the display board. Further, Patent Document 1 also proposes a wind turbine with blades attached to a rotating advertising body.
In the advertising tower of Patent Document 1, a rotating body is arranged around a support shaft, drag type blades are disposed on the longitudinal intermediate outer periphery of the rotating body, a light emitter is mounted on the blade, and a space between the support shaft and the rotating body. The generator and the battery are arranged so as to co-rotate with the rotating body.
JP-A-8-137420

In the advertising tower of Patent Document 1, the weight of the rotating body is remarkably heavy and the drag blade acts as a brake on one side of the support shaft. Therefore, the rotating blade does not rotate unless high-speed wind such as typhoon blows. Even if it rotates, it cannot generate electricity with a generator that co-rotates on a rotating body.
In addition, it is said that wind power generation cannot be put into practical use unless a wind speed of 4 m / s or more blows for 2000 hours or more per year (approximately 5.5 hours per day). The wind speed of 4m / s is a state in which the branches of the tree are constantly swaying, so there are few winds of such wind speed throughout the year, so continuous wind power generation with ordinary windmills is impossible, and advertising lighting with wind power generation is impossible. It is virtually impossible to continue.
The display tower requires a certain installation area, and has a large power consumption because it draws electric wires from outside lines for lighting. If in-house power generation is possible with this power alone, the maintenance cost can be reduced. The present invention incorporates a high-performance wind power generation mechanism that generates power even at low wind speeds in a display tower, efficiently generates power by rotating a windmill at a high position, and can continuously illuminate a display body with the power generated by wind power. The purpose is to provide a display tower.

  The specific contents of the present invention are as follows.

The display body can be illuminated with the electric power thus obtained.
The display body is projected outward from the support frame body at the outer surface position of the blades and is located in multiple radial directions that pass through the axis of the vertical axis wind turbine. You can watch. Moreover, since the wind which hits a display body is guide | induced to the blade | wing direction of a windmill, the air volume which strikes a blade | wing increases, the rotational efficiency of a windmill is improved, and electric power generation amount is increased.

(2) Since the illumination display tower of the invention described in claim 3 has a plurality of blades arranged on one longitudinal main shaft of the support frame, the shaft torque is large even at low wind speeds. Since the power generation efficiency is excellent, it is possible to sufficiently supply power for a large display body.

  (4) In the vertical axis wind turbine according to the invention described in claim 4, since the blade cage is formed at the ring edge of the blade support, by arranging the blade with a long chord length in the blade cage, The blade can be easily attached and can be fixed firmly and stably.

[Example 1]
Examples of the present invention will be described. FIG. 1 is a plan view of a main part of an illumination display tower of the present invention, FIG. 2 is a front view of the main part, and FIG. 3 is a front view of the illumination display tower showing the whole.
In the illumination display tower (1), the display body (3) is disposed above and outside the support frame (2). The support frame (2) is framed by a plurality of support columns (4) and a plurality of shaft supports (5) arranged in a multi-stage manner on the support columns (4).

The support frame (2) is set to a required height and size. In the upper part visible from a distance, a plurality of support arms (6) are located outside the support frame (2), in a plurality of radial directions passing through the central axis, and projecting outward in the horizontal direction (4 in the figure). ).
As shown in FIG. 1, the support arm (6) has a wide base and is formed so as not to be refracted by strong winds.

  The display body (3) is disposed vertically between the upper and lower support arms (6). The display body (3) is, for example, a vertical rectangular hollow body, transparent plates are stretched in parallel on both wide surfaces, and an illuminating lamp (3a) is disposed therein. A display text image (3b) is displayed on the transparent plate. Since the display body (3) is set in the radial direction of the support frame (2), it can be viewed from multiple directions.

In the illumination display tower (1), a plurality of shaft supports (5) are arranged on the support frame (2) inside the support frame (2). Each shaft support (4) is framed, for example, in a quadrangular shape, and vertical and horizontal bars are assembled inside, and a bearing (7) is disposed at the center thereof.
One vertical main shaft (8) is rotatably supported through the upper and lower bearings (7), and the lower portion of the vertical main shaft (8) is connected to the generator (9). Reference numeral (10) denotes a storage battery.

A blade arrangement section (11) is set between the pair of upper and lower bearings (7). In each blade arrangement section (11), lift type blades (12) are arranged via blade support bodies (13), respectively.
In the cross-sectional plan view, the lift-type blade (12) is formed in a substantially fish shape with a thick front part and a thin rear part facing the rotation direction.

  When this lift-type blade is rotated by other force, the air at the front of the blade (12) is compressed, the air density is increased, and the atmospheric pressure is increased. It flows at low speed at high speed, and the blade (12) is pushed forward as a reaction.

  As shown in the figure, the blade (12) has an upper and lower end inclined at an inclination angle of about 45 degrees in the longitudinal main axis (8) direction to form an inclined portion (12a). The number of blade arrangement sections (11) in which the blades (12) are arranged is appropriately set according to the size of the blades (12) and the power generation capacity of the generator (9).

  That is, the power generation capacity of the power generator (9) is determined in accordance with the amount of power required for lighting the display body (3). The wind receiving area of the blade (12) is calculated according to the axial torque required for the rotation of the generator (9), the number of blades (12) that matches the wind receiving area is selected, and the blade arrangement according to the number of blades is selected. The number of stages in the area (11) is selected.

Since the blade (12) has the inclined portion (12a) formed at the upper and lower tip portions, the wind flow that dissipates upward and downward during rotation is suppressed and the rotational force is increased.
In addition, the wind current hitting the inclined portion (12a) has a function of generating a negative pressure and gathering the wind current from other areas to make a rotational force in order to slide the inclined surface at high speed, and there is no inclined portion (12a). Compared to the direct blade, a large improvement in rotational efficiency has been confirmed by experiments.

The blade (12) has two blades in each blade arrangement section (11), and the phase of each blade (12) is displaced up and down by an angle obtained by dividing 360 degrees by the number of blade arrangement sections (11). ing.
Thereby, the phase of each blade (12) is a constant interval in a plan view, and the phases do not overlap vertically. The reason for using two blades is that when the number of blades is large, the turbulence of the previous blades causes the subsequent blades to stall in the process leading to high-speed rotation, making it impossible to rotate the blades as a whole.

  Since the display bodies (3) are respectively disposed at a plurality of positions in the radial direction passing through the center of the support frame (2) outside the blade arrangement section (11), in FIG. Since the wind hits the display body (3) and flows in the direction of the blade (12), the blade (12) is subjected to an air volume of 1.5 times the rotational diameter, so the vertical axis wind turbine (14) The rotation efficiency can be increased, and the power generation efficiency can be increased even at low wind speeds.

In the illumination display tower (1), the vertical axis (8), the blade support (13), and the blade (12) constitute a vertical wind turbine (14). A wind generator (9) is added to the wind power generation mechanism.
In FIG. 1, when the wind indicated by the arrow B blows, the wind hitting the display body (3) is blocked, increasing the density and increasing the atmospheric pressure. As a result, since the blade (12) rotates at a high speed in the direction of the airflow flowing downwind, the rotation efficiency of the blade (12) is increased.

  In the illumination display tower (1) of the present invention configured as described above, the vertical wind turbine (14) rotates even when the wind speed is 4 m / s or less, and the blade (12 ) Are arranged in multiple stages, the shaft torque is large, and the large cogging torque of the generator (9) can be easily overcome to generate power.

The electricity generated by the generator (9) can be stored in the storage battery (10) and used as a power source for the illumination lamp (3a) of the display body (3) at night. The extra power can be used for other power sources or sold.
Reference numeral (15) in FIG. 2 is a roof, and a solar power generation panel can be stretched on the upper surface.

[Example 2]
FIG. 4 is a front view of an illumination display tower showing the second embodiment. The same parts as those in the previous example are denoted by the same reference numerals and description thereof is omitted.
In the second embodiment, the display body (3) is also disposed on the top of the support frame (2). The display body (3) has a plate shape in a circular shape in plan view. The beam of the illumination lamp is irradiated from the support frame (2).

Further, in the middle of the height of the support frame (2), the display body (3) is arranged in an annular shape at a portion other than the side surface where the blade (12) is located. The display body (3) can be an electronic bulletin board for displaying the display text (3b) using a light emitting diode.
Accident information, traffic jam information, weather information, etc. can be displayed on highways, etc., and light-emitting diodes have low power consumption, so their usability is high. Reference numeral (16) in the figure denotes a streetlight.

[Example 3]
FIG. 5 is a front view of an illumination display tower showing the third embodiment. The same parts as those in the previous example are denoted by the same reference numerals and description thereof is omitted.
In the third embodiment, two pairs of support frames (2) are arranged, and a horizontally long display body (3) is placed between them.

  The support frame (2) is erected in a pair on the left and right sides of the expressway, for example. A horizontal girder frame (2a) is installed between the left and right support frame bodies (2) at a position that is at a moderate height and away from the position of the blade (12) of the vertical axis wind turbine (14). The display body (3) is fixed to the horizontal girder frame (2a).

A net is stretched around the support frame (2) at the site where the vertical axis wind turbine (14) is located. Further, since the blade (12) is made of synthetic resin and is lightweight, even if it is damaged, it does not become an impact force against other objects and does not protrude from the net and scatter outward, so that it does not become an obstacle to the road.
There are support frames (2) on the left and right of the display body (3), and vertical wind turbines (14) are arranged on each of them to generate electric power. Can be used for body power.

  FIG. 6 is a plan view of a blade support of the vertical axis wind turbine (14), and FIG. 7 is a front view thereof. This vertical axis wind turbine (14) has an annular edge (13a) formed in the peripheral portion of the blade support (13), and a blade rod (13b) is recessed in the peripheral portion of the annular edge (13a). ing. The blade (12) is fitted to the outside of the blade rod (13b), and is fixed by an arbitrary attachment means.

  When the blade (12) is disposed around the longitudinal main shaft (8), the rotational balance is slightly different even if the mounting position is moved by several millimeters. For example, if one of the two blades is moving forward, the result is that the regular interval is long before and short behind, and even a difference of 1 mm affects the rotation as a difference of 2 mm. . When the rotational balance is lost, the wind strikes from one direction, and thus the rotational force balance is lost, which hinders smooth rotation.

In this vertical axis wind turbine (14), the blade collar (13b) is formed on the ring edge (13a) around the periphery of the blade support (13), so the blade (12) is fixed at an accurate position. Can do.
Since it can fix over the chord length of a blade | wing (12), the twist of the blade | wing (12) by a high wind pressure can also be suppressed, and rotation efficiency can be stabilized.

  FIG. 8 is a plan view of the blade support of the vertical axis wind turbine (14). In the vertical wind turbine (14), a blade rod (13b) is recessed inside the ring edge (13a) of the blade support (13). The blade (12) is fitted into the inner side of the blade cage (13b), and is fixed by any attachment means.

As a result, even if the chord length of the blade (12) is long, the entire length of the outer side along the chord length of the blade (12) abuts against the blade rod (13b), so it is stable even if centrifugal force is applied to the blade (12). And firmly fixed.
In addition, positioning is easy and the mounting workability is excellent, and the ring edge (13a) maintains a stable rotation due to the rotation inertia.

  In addition, this invention is not limited to the said Example, A design change can be suitably performed according to the objective. Each part in each embodiment can be combined.

  Although it is an illumination display tower, it can be used as an illumination tower because it can substantially generate power by wind power.
