Description

Universal gate switch using inertia torque {UNIVERSAL GATE SWITCH USING INERTIAL TORQUE}

The present invention includes a rotating mass driven and revolved by a motor to the outside of the rotating shaft, and has a magnetic gear that rotates in engagement with the rotating mass, and the magnetic shaft and the rotating shaft are fixedly coupled to rotate the rotating shaft by driving the motor. The present invention relates to a universal gate switch using inertial torque that locks or releases an actuator such as an external valve by the rotary shaft, and further turns on or off an external switch by the rotary shaft.

In general, valves that are opened and closed by rotation, such as gate valves, are difficult to open and close remotely.

However, in the case of such a manual valve, even if an emergency situation arises and the manual opening and closing is difficult for a person to access, the opening and closing is not performed in a timely manner, and there is a risk of enormous damage to property and life.

In addition, the valve may be automatically opened and closed by directly connecting the rotating shaft of the motor to the shaft of the manual valve. In this case, the motor rotates by reaction when the motor is not fixed. Problems can arise if there is no suitable place to fix the motor around, as in.

Furthermore, in the case of an on / off switch such as an emergency switch, it is generally difficult to turn it on and off remotely, so that it is generally used manually.

However, even in the case of such an emergency switch, even if an emergency situation occurs and an attempt is made to turn it off manually, when an emergency has already occurred and a person is inaccessible, the emergency switch cannot be turned off in a timely manner, causing a great loss of property and human life. There are many.

An object of the present invention is to enable manual opening and closing of the manual valve and switch in a distant position and at the same time open and close automatically.

Another object of the present invention is to simplify and compact the structure by using the principle of dynamics, without opening and closing the manual valve and switch to a complicated hydraulic.

Another object of the present invention is to propose a structure that can be adapted to various types of valves and switches.

Still another object of the present invention is to freely open and close valves and switches freely by installing it in a place where it is difficult to fix the motor, such as in space.

Referring to the method of remotely controlling the universal gate switch using the inertial torque according to the present invention. When the motor drive switch is turned on through the transmitter from the outside, the receiver located in the storage box 38 receives it, and the motors 40 and 42 rotate under the control of the controller. As a result, the adapter 12 at the tip of the rotary shaft 10 is rotated. Valve is mounted on the switch or the switch is turned on or off by the lever 14 mounted on the adapter 12.
