Abstract

PURPOSE:To requir no blower and facilitate the maintenance and inspection, etc. by continuously providing spiral grooves on the outer periphery of a flywheel from the lower portion to upper portion of the flywheel so that the flywheel itself serves as a fan. CONSTITUTION:Spiral grooves are continuously provided on the outer periphery of a flywheel 13 from the lower portion to upper portion. Therefore, when the flywheel 13 is rotated, the wind is fed from the lower portion to upper portion of the flywheel 13, thus cooling the outer periphery of the flywheel 13. That is, the flywheel 13 itself serves as a fan as a result of its rotation and the wind flows along the outer periphery of the flywheel from the lower portion to upper portion of the flywheel, thus cooling the flywheel itself. Accordingly, a separate blower for cooling the flywheel is not required, thereby the diameter D of the concrete foundation 20 can be reduced.

Description

Detailed Description of the Invention: Directly connected to a generator with an electric starting means that converts the inertial energy of all rotating bodies into VC and stores it, converts it to electric energy again and supplies it when necessary. This invention relates to a flywheel device.

In this type of device, the flywheel device is entirely directly connected to a generator connected to a separate starting rotation motor, or a stationary type using a thyristor. A device that uses all of the devices includes one in which a flywheel device is directly connected to a generator motor that also serves as a starting rotation electric motor and a starter motor. In order to obtain a large inertia effect, the diameter of the flywheel increases and the weight increases by several hundred tons. ：、Achieving things〉；Roro.

Therefore, it is possible to prevent shaft misalignment, reduce vibration, and improve installation +f.
From the viewpoint of reducing n fJi, the horizontal axis type Puri is also configured into a vertical axis type.

Below, the excitement begins! ``As a generator with means D, both the conventional device and the device of the present invention are explained in the case of one generator.''

The following steps are taken to operate the flywheel directly connected to the generator motor. First, the Eri generator motor () is started as a motor by applying the energy from the thyristor starting device U, and the flywheel (1) is accelerated at a constant rotational speed and stored as rotational inertia energy. Accordingly, it operates as an original electric motor Il + a power generator, converting it into electrical energy and supplying it.

Therefore, in order to store a large amount of rotational inertia energy, a flywheel with a large diameter and a high M amount is required.Moreover, since a single disc has a high M(i), manufacturing and transportation problems are required. Due to the restriction 1, the flywheel is divided into multiple discs and stacked on top of each other and rotates at high circumferential speed7), so the friction loss with electricity is large and heat is accumulated on the outer periphery and inside. Since the temperature is quite high, it is necessary to cool it down, so a separate blower (c) is required.
It is larger than the separately installed blower of RT, &D, and as a result, the diameter of the pit of the concrete foundation (a) becomes thicker19, resulting in higher civil engineering costs.

In addition, the gap between the flywheel u3 and the concrete foundation (4) needs to be increased in order to reduce pressure loss, but for this purpose, the friction loss of the flywheel (13) is increased, and a separate blower is installed. −(E) and Kyukikai Cooling ((
The capacity of J (c) increases by 7IO'f.

The conventional flywheel device with T-trap mechanism is constructed as shown above, but due to the friction loss of the flywheel and the heat generated by the mechanism, the A separate bevel blower was required, which often resulted in disadvantages such as the diameter of the concrete foundation becoming larger.

In order to eliminate the above-mentioned drawbacks of the conventional ones, the invention has been made by providing spiral grooves on the outer periphery of the flywheel. A flywheel device that can eliminate the need for a separate blower to cool the flywheel. is intended to provide.

The entire drawings of an embodiment of the present invention will be described below.

In other words, the rotation Vc1 of the flywheel 0.1 is such that the flywheel itself becomes a fan, and the air flows from the bottom of the flywheel to the top through the outer circumference I' of the flywheel, so the flywheel itself is cooled. Since a separate blower (2) for cooling the flywheel is not required, it is economically inexpensive and eliminates maintenance and inspection. Also, since there is no separate blower, the diameter of the concrete foundation is small (
