Abstract

The present invention relates to a motor actuator for a fire extinguisher of an automatic fire extinguisher for a gas range. The motor actuator receives a signal from the main controller and automatically opens the extinguisher outlet of the fire extinguisher by a motor drive when a fire occurs in the gas range. All.

The motor actuator has a shape in which a power transmission gear directly opens the extinguishing fluid ejection opening to have a gear and a case capable of supporting and protecting the parts, and to open the extinguishing fluid ejection opening, The motor actuator is located on the side of the fire extinguisher head, and it is composed of a structure that can be fixed by bolting the fire extinguisher.

Therefore, the present invention improves the operation reliability by ejecting the extinguishing fluid by using a gear that transmits power and minimizes the interference of height by placing the motor actuator on the side of the fire extinguisher head. It is to suppress the big accident by suppressing it early.

Description

Motor Actuator for Fire Extinguishers {MOTOR ACTUATOR FOR EXTINGUISHER}

The present invention relates to a motor actuator for fire extinguisher, and more specifically, it is installed in the fire extinguisher of an automatic fire extinguishing apparatus that can open fire extinguisher automatically by the operation of the motor in response to the signal of the main controller when a fire occurs in the gas range. The present invention relates to a motor actuator for a fire extinguisher that opens a digestive fluid ejection push pin with motor power.

In the conventional method of operating the push pin of the motor actuator for fire extinguishers, the extinguishing fluid ejection push pin is ejected by using a separate connection device such as a lever and a cam in addition to the power transmission gear, so that the extinguishing fluid is ejected. The operating reliability has fallen.

And when the motor actuator for fire extinguisher is installed in the fire extinguisher, it is composed of a protective cap to protect the separate fixing bracket and the device that pushes the push pin and the push pin.The assembly cost is high. It was a problem.

In addition, the position of the motor actuator for fire extinguishers was also mounted on the upper part of the fire extinguisher, so it was restricted in the place where the fire extinguisher was installed.

Therefore, the present invention was devised to solve the above-mentioned problems, and the extinguishing fluid ejection push pin of the fire extinguisher is operated by using the power gear itself as a push switch without using a separate device such as a lever and a cam. In the method of fixing the motor actuator and the fire extinguisher, the motor actuator and the fire extinguisher are simply and securely fixed by bolts, and the position of the motor actuator is located next to the fire extinguisher head to minimize the interference with the installation place.

Hereinafter, the accompanying drawings will be described in detail.

1 is a side cross-sectional view showing an embodiment according to the present invention, the present invention has a plurality of gears for power transmission for transmitting the power of the motor 11 and the motor that is operated by receiving a signal from the main controller when a fire occurs in the gas range; A push gear 25 in which a push switch is formed on a power transmission gear to press the extinguishing liquid ejection push pin, and a motor actuator for a fire extinguisher having a case type 31 and 32 for supporting and protecting the parts.

When described in detail by the operation of the present invention is as follows.

When a fire occurs in the gas range and receives a signal from the main controller, the motor 11 rotates.

When the motor 11 rotates, the wedge gear 21 integrated with the motor rotates at the same time.

As the wheel gear 21 rotates, the helical gear 22 in close proximity to the wheel gear 21 is driven, and the helical gear 22 again rotates the reduction gear 1 (23), which is the next gear, to reduce the gear. The reduction gear 2 (24) rotates under the power of 1 (23).

As the reduction gear 2 24 transmits power to the last gear, the push gear 25 rotates.

As the push gear 25 rotates, the push switch 26 integrated with the push gear 25 rotates to press the push pin 101 to eject the extinguishing liquid.

In addition, the left and right cases 31 and 32 are configured to have a shape such as a boss and a hole so that the fixing plate and the gears for supporting and fixing the motor 11 are rotatable.

The left and right cases 31 and 32 also serve to protect the motor 11 and the gears and the like from external shocks and the environment.

In addition, the left and right sides 31 and 32 of the sides of the fire extinguisher with a bolt 33 to match the hole in the nut seat processed in the fire extinguisher by processing a hole for assembling the bolt 33 for engagement with the fire extinguisher And assemble the motor actuator for the fire extinguisher.

When a fire occurs in the gas range, when the heat sensor senses a signal to the main controller, the main controller sends a signal to the motor 11 again and the motor 11 rotates.

The rotational driving force of the motor 11 is sequentially driven by a worm gear 21 press-fitted into the motor, a helical gear 22, a reduction gear 1 (23), a reduction gear 2 (24) and a push gear 25, which are the next gears. As the push gear 25 is transmitted and the push gear 25 rotates, the push switch 26 integrated with the push gear 25 rotates.

When the push switch 26 presses the push pin 101 while rotating toward the push pin 101, the extinguishing fluid ejection port of the extinguisher is opened to extinguish the fire by ejecting the extinguishing fluid filled in the extinguisher.

Fire extinguisher motor actuator of the present invention uses a portion of the power transmission gear itself as a push switch to reduce the number of parts to reduce the cost, increase the operation reliability and efficiency, and work to fix the assembly of the motor actuator and fire extinguisher with bolts Reduced assembly time, reduced assembly costs, increased stability by making it robust and prevented from loosening. The motor actuator for fire extinguishers was placed next to the fire extinguisher head to reduce overall fire extinguisher height to minimize interference with the location where the fire extinguisher can be installed.
