Description

Attached vertical-axis wind generater

Wind power generation system is a clean energy source, and since 1970, after the energy crisis, the world has already reached the practical stage through continuous use technology development, and commercialization is actively progressing all over the world. Recently, active researches are being conducted on hybrid wind power generation systems and large-capacity wind power generation systems in which solar, diesel, and wind powers are combined.

In particular, the empirical research on the development and installation operation of vertical axis wind power generation system in Korea from 1992 to December 1996 on the vertical axis wind power generation was carried out using the composite material laboratory affiliated with Korea Fiber Corporation. Alternative energy generation systems for street lamps, such as street lamp systems using photovoltaic cells, as in the case of US Patent No. 4,200,904, use only solar energy as an energy source, and solar power street lamps in US Patent No. 5,149,188, There is a photovoltaic street light system using a combination of light and wind. However, the above-mentioned US Patent No. 4,200,904 and US Patent No. 5,149,188 are intended to provide a street light that can be installed in an area in which it is difficult to connect with a battery in the form of an independent power type. Therefore, the above systems, which are stand-alone power systems, run out of electricity stored in the battery when power generation is insufficient for several days. In addition, when the battery is at the end of its life, maintenance is required, such as replacing the battery. In particular, when more power is generated than the storage capacity of the battery, the surplus power produced by the generator is to be discarded.

Therefore, the main object of the present invention is to provide a means for attaching a grid-connected small vertical axis wind power generation system to street lamps located around a road, thereby using the power generated by the power generation system in the street lamp 1 as an existing load. And supply the surplus produced power to the grid linkage, and if the power produced for the use of the street light is insufficient, the insufficient power is supplied from the grid linkage power line, which is the supply power line, to increase the reliability of the streetlight operation, and the surplus It is to provide a vertical axis wind power generation system (2) with a street lamp as a small-scale distributed power supply device for supplying clean alternative energy to the grid through grid connection lines.

A feature of the present invention for achieving the above object, in that the street light is formed in the center or the periphery of the road, leaving only the lower end (8) of the existing street light, cut off the upper end of the street lamp including the street lamp, and cut It is configured to form a vertical axis power generation system having a height similar to that of the street lamp by pressing and fixing it to the lower end 8 of the existing street lamp, and attaching the street lamp 1 to the upper portion of the vertical axis power generation system 2.

The present invention will be described in detail with reference to the drawings.

1 is an elevation of street lamps on a general road, the street lamps are made of circular tepa-type and octagonal-tepe-type steel pipes or stainless steel pipes, and various types of streetlights using cast iron are installed in places requiring aesthetics. However, up to now, most of the street lamps are street lamps illustrated in FIG. Street lamps have various heights depending on the installation site, but most streetlights are 8-12 meters in height.

The present invention is to cut the street lamp by using an oxygen welding machine, a laser cutting machine, or an electric cutting mechanism in order to provide the above-described street lamp-mounted vertical axis wind power generation system (2). The street lamps cut at the top end perform structural reinforcement work required by the wind generators to be attached, the shaft calibration and correction work for the street lamps, and the cutting surface treatment. Axial correction aims to prevent stress generated when the rotor of the vertical axis wind turbine rotates eccentrically and provides an easy means to fix the vertical axis wind turbine through the cutting surface treatment.

4A and 4B are cross-sectional views of the foundation of the cut street lamp 8, Figure 4A is a reinforcement of the cut street lamp by using a triangular support (9), Figure 4B is a foundation work around the street lamp Fixing by fixing the expansion plate 10 coupled with the bottom fixed steel plate of the street lamp, and combines the reinforcing rod (12) connecting the expansion plate and the street lamp in order to resist the stress applied to the horizontal. The upper part of the cut street lamp is configured to install a mounting plate 11 for attaching the wind power generator to facilitate the installation of the wind power generator.

Figure 2a is a front view of a conventional horizontal axis wind power generator, the horizontal axis wind power generator is capable of self-starting and has a relatively wide operating area, and enters a large-scale mass production stage worldwide, occupy most of the wind power generators currently used. Has been popularized but has the disadvantages of complicated power transmission system, high maintenance cost and complicated mechanical mechanism. In particular, energy loss of yawing system occurs and additional devices for wind direction such as wind direction tracking device are required.

Figure 2b is a front view of a conventional Darius-type vertical axis wind turbine, the vertical axis wind turbine is easy to maintain and repair, operating regardless of the wind direction, easy to maintain, and excellent structural stability, while Starting conditions must be secured such that starting power is required, and a larger installation area is required as compared to the horizontal axis wind turbine, and the rotor blades are larger than those of the horizontal axis wind turbine.

Figure 2c is a front view of a conventional Gyromill vertical shaft wind turbine, Gyromill vertical shaft wind turbine is a type that solves the difficulty of improving efficiency and transport in the form to mix the advantages of the vertical shaft wind turbine and the horizontal shaft wind generator As shown in 2C, it has an H-type rotor. However, as shown in FIG. 2c, the rotor of the Gyromill-type generator is wider and larger than the Darius type, and thus shows a problem in that shadows are generated by the street lamp lighting when attached to an existing street lamp. In addition, the weight of the rotor is heavy, there is a disadvantage that the structural burden on the existing street lamp.

Therefore, the present applicant has analyzed the advantages and disadvantages of each of the above-mentioned wind generators when selecting a street light-type wind generator, and concluded that the vertical Darius type shown in FIG. 2B is the best. In other words, according to the convenience of maintenance and the characteristic of operating regardless of the wind direction, the separate wind direction tracking device is unnecessary, so it has good structural simplicity and form symmetry, and it is possible to replace the starting power which is the disadvantage of Darius wind generator. Because it can be supplied from, and also attached to the street lamp because it has a miniature rotor, the disadvantage of manufacturing and installation is largely eliminated. In addition, since the rotor wing area is small, there is little obstacle in performing road lighting, which is a unique function of street lights.

3 is a partial cross-sectional view of a street lamp with a street lamp-mounted Darius-type vertical axis wind generator 2 according to a preferred embodiment of the present invention. The foundation reinforcement work of the streetlight substructure of Figure 4 is provided with a mounting plate 11 for the installation of a wind power generator to the street lamp to connect a separately produced wind generator (2), and the street light (1) on the top of the generator Connected.

5 is an assembly road of the vertical axis of the wind turbine generator according to the present invention is attached to the end of the street lamp, the street lamp is responsible for the road lighting, the fastening pipe 15 that can be fastened to the upper portion of the wind turbine at the bottom of the upper shareholder Consists of. In addition, the mounting plate 11 of the street lamp pole 8 and the bottom of the wind power generator for fastening the fastening tube 15 and the bottom portion of the wind turbine is shown to be coupled with the mounting bar, the fixing of the street lamp pole and the wind generator Bolts and nuts are used for this purpose.

6 is a detailed enlarged cross-sectional view of the rotor. Similar to a conventional vertical axis generator, the Darius-shaped vanes are connected to the rotary wheel assembly 19, and the upper bearing assembly 17 of the rotary wheel assembly 16 is spaced in proportion to the length of the street light so as to rotate the rotary wheel assembly 19. ) Is configured. Bearings used in the upper and lower bearing assemblies are generally radial bearings and thrust bearings embedded in the bearing housing to support vertical and horizontal loads. However, in the case of a micro rotor such as the present invention, the weight of the rotor and the structure is light. Can be replaced with a suitable bearing. The power is transmitted to the speed increaser 24 via the rotating part according to a conventional method.

As shown in the detailed internal view shown in FIG. 9, the kinetic energy transmitted from the power transmission shaft 18 is increased to an effective rotational speed through which the generator 25 can rotate via the speed increaser 24. As shown in FIG. The speed increaser 24 is manufactured by a conventional method such as a planetary gear train in consideration of the rotational speed and power generating capability of the rotor. The rotational speed increased through the speed reducer is connected to the generator through the power transmission shaft. The generator should be easily connected to the grid and should be selected to have high energy conversion efficiency. Most small wind generators are used as stand-alone power supplies, but according to the present invention, in the case of grid-connected small vertical axis wind generators, power generation is generated by direct current generators for system linkage and then DC power generation is synchronized with inverters. In this case, AC generators are used because problems such as noise effects and waveform defects are applied to the inverter. Among the alternators, induction type asynchronous generators do not need power stabilization equipment for generating power at the time of grid connection, and have the advantages of simple structure and low price. The braking device 20 uses the hydraulic device 21 to stop the rotor in an emergency situation such as an overwind condition or a stop of the KEPCO system line. The control device 27 is configured to remotely control the wind power generation system and a safety device capable of system protection, and to monitor the state of the system.
