In the fire protection window opening and closing device proposed in the preferred embodiment of the present invention, the connection state of the electric motor unit and the operation unit by the clutch unit is shown.

Fire fighting window opening and closing device according to the present invention, as shown in Figures 1 to 3, and the stationary motor unit 10 for generating a rotational force in the forward or reverse direction according to the direction of application of the drive current applied from the power supply; An operation unit 20 for receiving a rotational force from the stationary motor unit 10 and pulling the window installed in a hinge or sliding structure to the window frame and closing the window; And a controller 30 for controlling the current supply of the forward and reverse motor unit 10.

In the fire fighting window opening and closing device 1, when the control unit 30 applies a driving current to the forward and reverse motor unit 10 in the forward direction, the forward and reverse motor unit 10 rotates the rotation shaft 11 in the forward direction to generate a forward rotational force. And, the operation unit 20 receives the rotational force in the forward direction from the rotary shaft 11 of the stationary motor unit 10 through the operating shaft 21 to pull the window closed.

The operation unit 20 for opening and closing the window by applying the rotational force from the stationary motor unit 10 is a chain rope type to close the window by pulling the chain through the chain rope, a wire type to close the window by pulling the window through the wire, various Various forms known in the art may be adopted, such as a link type for opening and closing a window through a link structure.

However, in the present embodiment, the operating shaft 21 is rotated by applying a rotational force from the rotary shaft 11 of the stationary motor unit 10, the sprocket 22 fixed to the operating shaft 21, and the The chain rope type operation part 20 including the chain rope 23 adhered to the plaque 22 is adopted.

Therefore, when the control unit 30 receives the driving signal applied from the situation room or the like and applies the driving current to the forward / reverse motor unit 10 in the forward direction, the forward / reverse motor unit 10 generates the rotational force in the forward direction so that the operation unit 20 It is applied to the operation shaft 21, the operation shaft 21 to move the chain rope 23 attached through the sprocket 22 in the forward direction to pull and close the open window.

Then, when the control unit applies a current in the reverse direction to the reverse motor unit 10, the reverse motor unit 10 generates a rotation force in the reverse direction and applies it to the operating shaft 21 of the operating unit 20, the operating shaft 21 The reverse movement of the chain rope 20 attached through the sprocket 22 to open the closed window.

In addition, in the present embodiment, the clutch unit 40 is formed between the rotating shaft 11 of the stationary motor unit 10 and the operating shaft 21 of the operating unit 20, thereby interlocking them by the clutch unit 40. By configuring the state to be controlled, the electric opening and closing of the window through the drive of the stationary motor unit 10, and the manual opening and closing of the window through the manual operation is possible.

The clutch unit 40 may include a first clutch member 41 fixed to one of the rotating shafts 11 and the operating shafts 21 of the operating unit 20 and the stationary motor unit 10. And a second clutch member 42 which is installed on the remaining shaft in a retracted structure, and a solenoid 43 which sets the connection state with the first clutch member 41 by advancing and retracting the second clutch member 42. do.

Therefore, in the electric opening / closing state of the window through the drive of the stationary motor unit 10, the second clutch member 42 is advanced by the solenoid 43 and engaged with the first clutch member 41, in this state. The motor unit 10 and the operation unit 20 form an interlocking state.

Then, in the manual opening and closing state of the window, the second clutch member 42 is retracted by the solenoid 43 so that the engaged state with the first clutch member 41 is dismantled, but without the braking resistance by the forward and reverse motor unit 10. You can manually open and close the window by pushing it manually.

On the other hand, in the present embodiment by adding a voltage controller 32 for boosting the strength of the current applied to the forward and reverse motor unit 10 to the control unit 30, the operator closes the window constructed through the voltage controller 32 According to the resistance to increase and adjust the strength of the current applied to the stationary motor unit 10.

Normally, a 24V fire current is applied to the building from the power supply unit, and in this embodiment, a driving current boosted by the fire current to 25V-30V through the voltage controller 32 is applied to the stationary motor unit 10.

Thus, by adjusting the strength of the current applied to the stationary motor unit 10, it is possible to control the opening and closing speed of the window, it can be configured to stably open and close the windows having different opening and closing resistance within the set time.

In addition, in the present invention, in the fire fighting window opening and closing device 1, a load measuring unit 33 for detecting the actual load of the stationary motor unit 10, and a memory unit in which the preset load of the stationary motor unit 10 is stored in advance. In addition to (31), if the actual load exceeding the set load amount is measured during the closing of the window by electric movement, the closing of the window or the opening of the closed window are made to pause the closing of the window.

The load measuring unit 33 measures the actual load of the stationary motor unit 10 through a current value, a voltage value, or a resistance value applied to the stationary motor unit 10, which is widely used in electric and electronic fields. It is a technique of well-known tolerance utilized.

However, in the present invention, such a load measuring unit 33 is added to the fire fighting window opening and closing device 1, and when the actual load exceeds the set load amount by an obstacle between the window and the window frame to be electrically closed, the electric closing of the window is performed. By stopping, the safety problem is solved by the electric closing of the window continuously in the state in which the human body part or obstacle is sandwiched between the window and the window frame.

For example, when the actual load measured by the load measuring unit 33 is lower than the set load amount, the drive current is continuously applied to the forward and reverse motor unit 10 in the forward direction to realize the electric closing of the window, but the window is electrically closed. If the actual load amount measured through the load measuring unit 33 exceeds the set load amount due to an obstacle or the like between the window frame and the window frame, the controller 30 cuts off the supply of the drive current applied to the forward / reverse motor unit 10 so that The motor closing is temporarily stopped or the supply current of the driving current applied in the forward direction is reversed to open the motor closing window.

Thus, the present invention can solve the safety problems of the electric closing of the window continuously in the state in which the body parts or obstacles of people between the window and the window frame is sandwiched.

However, as described above, each of the windows to be constructed has an opening and closing resistance of individual strength, the actual load of the forward and reverse motor portion may be increased by the opening and closing resistance.

When the actual load measured by the opening and closing resistance in this way exceeds the set load amount stored in the memory 31, the controller 30 stops closing the window or closes the window even when no obstacle is caught between the window and the window frame. The stationary motor part 10 may be malfunctioned, such as opening and closing.

However, in consideration of the opening and closing resistance of each window to be constructed, it is practically difficult for the installer to programmatically update the set load stored in the memory 31 of the controller in the field, thereby preventing a malfunction of the controller according to the opening and closing resistance.

Therefore, in this embodiment, the load amount adjustment controller 34 which arbitrarily increases or decreases the actual load amount measured by the load measurement unit 33 between the load measurement unit 33 and the control part 30 is added.

By adding the load adjustment controller 34 as described above, it is possible to stably detect the occurrence of overload of the forward and reverse motor unit 10 without malfunctioning according to the opening and closing resistance without changing the set load amount stored in the memory 31.

That is, the load amount adjustment controller 34 applies a load amount obtained by arbitrarily subtracting the load amount according to the opening and closing resistance to the load amount measured through the load measuring unit 33, and the controller 30 controls the subtracted load amount and the memory 31. In preparation for the set load amount stored in, it is to recognize whether or not the overload of the stationary motor unit 10.

Therefore, the contractor arbitrarily increases or decreases the actual load amount measured by the load measuring unit 33 through the load amount adjusting controller 34 and applied to the controller 30 according to the opening / closing resistance of the window to be constructed, and thus stored in the memory 31. Even without changing the set load amount, it is possible to stably recognize whether or not the overload of the stationary motor unit 10 occurs without a malfunction due to the switching resistance.

4 and 5 is a flow chart showing a control method of the fire fighting window opening and closing device according to the present invention in sequence, and the control method of the fire fighting window opening and closing device according to the present invention will be described in detail below with reference to FIGS. .

When the control unit 30 receives the driving signal through the wire or wirelessly in the situation room or the like, the control unit 30 applies a current to the forward and reverse motor unit 10 in the forward direction, and the forward direction generated by the forward and reverse motor unit 10. The window opened by the rotational force is electrically closed to one side.

In the electric closing process of the window, the load measuring unit 33 measures the actual load of the stationary motor unit 10, and the control unit 30 measures the actual load and the memory 31 measured by the load measuring unit 33. Prepare for the set load stored in.

At this time, if the actual load measured by the load measuring unit 33 is greater than the set load amount stored in the memory 31, the control unit 30 cuts off the drive current applied in the forward direction to temporarily stop the electric closing of the window, or By changing the direction of application of the driving current applied in the reverse direction so that the electrically closed window is electrically open.

For example, when the actual load amount is lower than the set load amount, a current is applied to the electric motor in the forward direction by a drive signal to achieve electric closing of the window, and an obstacle is inserted between the window and the window frame to be electrically closed, and the actual load amount is set. If exceeding, the control unit temporarily cuts off the supply of the drive current applied in the forward / reverse motor part to stop the electric closing of the window temporarily, or reverses the supply direction of the current applied in the forward direction in the reverse direction, so that the closed window By opening, sufficient time and space can be removed to remove body parts or obstacles between the window frame and the window.

Thus, in the present invention, the electric closure of the window is continuously performed in a state where a human body part or an obstacle is caught between the window and the window frame, and a body part such as an arm is injured by an electric closed window, or an obstacle is , Or physical deformation of windows, window frames, etc. can be prevented.

Thereafter, the controller 30 re-applies the current temporarily blocked to the forward / reverse motor unit 10 in the forward direction, or reapplies the current applied in the reverse direction to the forward / reverse motor unit 10 to achieve electric closing of the window. do.

By the electric closing of the window, and the obstacle between the window and the frame by the electric opening action, the window can be separated from the window and the window frame by repeatedly colliding with the window that is opened and then closed, thereby enabling a stable electric closing of the window. .

If the overload is continuously measured even if the electric opening and closing of the window are repeated as many times as the set number of times, the controller 30 determines that the obstacle cannot be removed, and re-applies the current in the forward direction to perform the electric closing of the window. Either stop or apply the current in reverse to allow the window to open electrically.
