Rotating mobile body equipped with electromagnets

Abstract

When raising and lowering a soot-cleaning machine inside a steel chimney, if magnets (permanent magnets) are used around the rotating body necessary for raising and lowering, once they are attracted to the inner surface of the chimney, a powerful electric motor with high torque is required to release the attractive force and rotate the body, so the overall configuration and cost of the device must be considered. [Solution] Instead of magnets (permanent magnets) around the rotating body, electromagnets are installed, and the function of generating magnetic attraction only when energized is utilized. By controlling the energization / de-energy of the electromagnets and the position of the commutator, the rotation function can move forward and backward, eliminating the need for an electric motor to rotate the rotating body.

Description

Technical Field

[0001] The present invention relates to a rotating moving body that utilizes the property of an electromagnet, which generates an attractive force only when energized and has no attractive force when not energized.

Background Art

[0002] When the electromagnet provided around the rotating body in FIG. 2 is a magnet (permanent magnet), once it is adsorbed to a steel plate (ferromagnetic material), a strong torque is required to remove the adsorption. To remove the adsorption and repeat the rotation by a rotary electric motor, a large and heavy electric motor with a large torque is required.

[0003] In Patent Document 1, when the chimney is made of steel, a magnet (permanent magnet) is fixed around the outer periphery of the rotating body. However, in the case of a magnet (permanent magnet), once it is adsorbed, a heavy electric motor with a strong torque is required to remove the adsorption force and rotate the rotating body. It is also necessary to consider the components, and the manufacturing cost becomes enormous.

Summary of the Invention

Problems to be Solved by the Invention

[0005] In the rotation of a conventional rotating body, it is normal to utilize the rotational force of an electric motor. To move up and down the inner surface of a steel chimney using the attractive force of a magnet (permanent magnet), once it is adsorbed, a heavy electric motor with a strong torque is required to remove the adsorption force and rotate it, resulting in a structurally enormous cost.

Means for Solving the Problems

[0006] To solve the above problem, the inventor devised the following: Idea 1 A power-generating structure that rotates and moves on a ferromagnetic material, The power generation structure comprises a plurality of electromagnets and at least one commutator, The electromagnet is arranged around the power generation structure, A lead wire, which is one side of the coil of the electromagnet, is connected to the lead portion. When the power generation structure rotates, the commutator is positioned to contact at least one of the lead portions. A rotating moving body equipped with an electromagnet, which, when the power generating structure rotates, causes the lead portion to come into contact with the commutator, and the electromagnet is attracted by the current supplied from the commutator, thereby enabling the power generating body to rotate and move on the ferromagnetic material.

[0007] Idea 2 The rotating moving body according to Invention 1, characterized in that the commutator's position is fixed in the horizontal and perpendicular directions when the power generating structure rotates. Idea 3 A rotating moving body according to invention 1 or 2, characterized by comprising two commutators.

[0008] Furthermore, to ensure clarity, the following statements should be clearly explained. A "ferromagnetic material" is a material that exhibits strong magnetism at room temperature and is a metal composed of iron, nickel, and cobalt. It may also be an alloy with other metals. An "electromagnet" is composed of a coil wound around a ferromagnetic material. A commutator, in a narrow sense, is a device that changes the direction of current every half rotation of the rotor of an electromagnet. However, this "commutator" is a "conductor" that only has the function of supplying current to the coil of the electromagnet. As mentioned above about "supplying" current, it is also possible to use the current in the reverse direction (the direction of receiving current).

Advantages of the Invention

[0009] A remarkable effect of the present invention is that although a conventional electric motor for rotating a rotating body is usually required, when the electromagnet is energized, an attractive force is generated due to its characteristic performance, and this attractive force creates a rotational movement function. A commutator is given a movement function, or by providing two commutators as a current switch and switching the energization to the commutator, a rotating moving body is provided with an electromagnet that can change the rotation direction forward and backward.

Modes for Carrying Out the Invention

[0011] The present invention will be described with reference to the drawings, but the present invention is not limited thereto.

[0012] Figure 1 shows the configuration of an electromagnet (1), with a coil (2) wound around it to generate an attractive force (magnetic flux) as an electromagnet (1) when energized, and leads (8) for energizing both ends (lead wires) (3) of the coil (2).

[0013] Figure 2 shows a rotating body (4) with multiple electromagnets (1) arranged around its outer circumference, and a commutator (5) inside the rotating body for energization. The position of the commutator indicates the position that determines the direction of rotation (forward direction).

[0014] Figure 3 shows a configuration similar to Figure 2, with multiple electromagnets (1) arranged around the outer circumference of a rotating body (4), and a commutator (5) inside the rotating body for energization. The position of the commutator indicates the location that determines the direction of rotation (rearward direction).

[0015] Figure 4 shows a rotating body (4) with multiple electromagnets (1) arranged around its outer circumference, and two commutators (5) inside the rotating body for energizing, with their positions indicating the location that determines the direction of rotation.

[0016] Figure 5 shows the directions of rotation, specifically the forward and backward directions.

[0017] Figure 6 shows a side view of a protective cover (7) for protecting the rotating body (4), commutator (5), and lead section (8) from dust. By the way, the protective cover (7) is fixed in place by a weight because the commutator is mounted on the outside of the rotating body. This is because a commutator can be designed to rotate if it is inside a rotating body, but not if it is outside of it. By the way, "fixed position" means that even when the rotating body rotates, it remains in the same position in both the horizontal and vertical directions.

[0018] Figure 7 shows an operating circuit diagram where current is supplied to the electromagnet (1) via the lead section (8) in the case of a single commutator (5).

[0019] Figure 8 shows an operating circuit diagram in which, in the case of two commutators (5), the direction of current flow can be changed by a switch (9) to change the rotation direction of the rotating body to "forward" or "backward". By the way, Figure 8 shows a forward / rear switch, but this forward / rear switch is, For example, when using this rotating mobile unit as a vacuum cleaner inside a chimney, it can also be used as a direction switch that switches from upward to downward movement when it reaches the top of the chimney, using a so-called top-end sensor. [Industrial applicability]

[0020] For the difficult task of cleaning the soot from tall, thick steel chimneys at thermal power plants and large factories, an automatic chimney soot cleaner that automatically raises and lowers itself to clean the soot would eliminate the need to install a winch at the chimney's exhaust port, thus avoiding dangerous work. Furthermore, at collection points such as delivery centers, if the wheels of an automated delivery vehicle are rotating bodies equipped with electromagnets, operation instructions (forward / backward, moving / stopping) can be easily given by switching the current on and off and using a current switch.
