JP2004278504A - Wind power generator using pet bottle - Google Patents

Abstract

<P>PROBLEM TO BE SOLVED: To provide a wind power generator characterized by the use of a PET bottle and overall safety based on absorption of shocks through utilization of soft, lightweight materials for windmill blades and other arrangements. <P>SOLUTION: Flexible polystyrene blades provided with PET bottle rotor heads are reinforced with blade supporting metal fixtures, while a rotor is fitted to a windmill shaft by means of joints. The windmill shaft is passed through a washer, PET bottle cap, bush, PET bottle itself, and washer in this order. A direct current motor-mounted gear box (plastic model application) is directly linked with the shaft through joints. The PET bottle is utilized as a fixation/protection cover for the gear box to constitute the main body of the wind power generator. The main body of the wind power generator is fixed to a wind power generator turn stand using bolts/nuts and fixation bands. Through these steps, the wind power generator using a PET bottle is completed. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

[0001]
[Industrial applications]
The present invention relates to reusing PET bottles as a part of a windmill without special processing, and to manufacturing a safe and low-cost wind power generator with flexible Utrac (polystyrene) blades.
[0002]
[Prior art]
Conventional wind power generators have many blades made of metal or hard resin, and the blades rotate at high speed with sharp angles, and can be easily installed anywhere with equipment for supporting heavy equipment. There was a problem with the spread in residential areas.
[0003]
[Problems to be solved by the invention]
An object of the present invention is to provide a lightweight and shock-absorbing device by using a plastic bottle or a flexible material for a part of a wind turbine device that solves the above-mentioned problems.
[0004]
[Means for Solving the Problems]
In order to achieve the above object, the plastic bottle used in the windmill of the present invention is used as a part of the windmill without special processing, thereby reducing the cost, and further, the blade has a flexible Utrac (polystyrene type). Use to form a safe wind generator.
[0005]
[Action]
Using a PET bottle as a support for the rotor creates a lightweight, non-corrosive windmill.
Since the blade is made of a lightweight and shock-absorbing material, even if it is rotating at a high speed, if it comes into contact with a human body, it is absorbed by the breakage of the blade, thereby reducing the risk.
Furthermore, it can be easily set up in a residential area because of its small size, light weight and low cost.
The wind power generators can be easily added at low cost without using any special equipment or materials, and high voltage and large current can be obtained by operating them in series or in parallel.

【Example】
1. A plastic (polystyrene) blade (2) with a rotor head (1) of a PET bottle is reinforced by a blade support (3) and a rotor (4) is attached to a shaft (4) by a joint (5). Attach the washer ▲ 9 ▼ PET bottle cap ▲ 6 ▼ Bush ▲ 7 ▼ Pass the PET bottle body ▲ 10 ▼ Washer ▲ 9 ▼ through the windmill shaft 4 in this order, and joint the gear box with a DC motor at ▲ 12 ▼ (For plastic model) (13) is directly connected. The gear box is fixed and protected by the PET bottle (8) to form the wind turbine generator body.
The wind turbine generator body is fixed to the generator direction support stand (15) with the bolt and nut (11) and the fixing band (16). With the above, a wind power generator using a plastic bottle is formed.
【The invention's effect】
【The invention's effect】
This invention creates a low-cost and safe wind generator, including the use of plastic bottles and the use of flexible and lightweight materials for windmill blades, thereby providing more wind generators in residential areas. The objective is to improve the environment if the consumption of commercial electricity is reduced by recycling and private power generation.
