Hereinafter, a facility safety management system and method according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic view of a facility safety management system according to the present invention.

Most of the structure for supplying water in the building supplies water to the water storage tank 10 through the water supply pipe 80. The reservoir tank 10 is usually present in the machine room together with the underground power supply facility. The water tank 10 is automatically controlled by a solenoid valve (not shown) in conjunction with the signals of the water level sensors 60 and 70. In order to further control the water pipe 80 before and after the solenoid valve, And so on.

The high water level sensor 60 is mounted in the water storage tank 10 to sense the amount of water in the water storage tank 10 and to control the water level using a solenoid valve (not shown) connected to the water supply pipe 80. However, if the solenoid valve malfunctions or the high-level sensor 60 fails, a safety accident occurs in which the water is overflowed and the machine room is flooded.

In the case of the present invention, the machine room including the water storage tank 10 is configured as follows to prevent the damage as described above.

Inside the water storage tank 10, a low water level sensor 70, a high water level sensor 60 and a dangerous water level sensor 65 may be included. In the case of the low-level sensor 70, the water in the water storage tank 10 is used to maintain the low water level. In the case of the high-level sensor 60, the water in the water storage tank 10 is a sensor for maintaining the high water level. The hazard level sensor 65 is a sensor for detecting the overflow danger level in the event of a failure of the high level sensor 60, and this signal is automatically closed.

Each sensor is connected to the control device 20. [ The controller 20 can collect and determine the information of the connected sensors, control the valve control system 100, inform the central control system (not shown) and inform the operator and / Or may include a function to notify the person in charge of the status or automatic call notification. The control device 20 may be located inside the machine room, but may be located in a separate space such as a management room, and is connected to the machine room through communication so that it can be detected and controlled remotely.

The water collection tank 40 may be configured to determine whether the machine room with the water storage tank 10 is submerged. The water collection tank 40 is configured to be lower than the bottom surface where the water storage tank 10 is located. That is, the bottom surface of the collecting tank 40 is configured to be lower than the water storage tank 10. When the machine room is submerged, due to the slight inclination and relatively low position in the collecting direction, all water can be configured to collect in the first collecting compartment (40).

A water immersion sensor (50) capable of sensing the immersion of the machine room is located in the water collection tank (40). The immersion sensor 50 can be connected to the controller 20 to send the sensing information to the controller 20. [ The water immersion sensor 50 can send sensing information to the controller 20 when the water reaches a predetermined height in the water collecting compartment 40.

In addition, a drain hole (90) may be formed in the collecting wall (40). The drain hole 90 functions to drain water into the water collecting compartment 40 and to send sensing information to the control device 20 without any feedback to the machine room, can do.

A fire sensor 30 capable of sensing a fire or the like inside the machine room can be separately provided inside the machine room and the fire sensor 30 can be connected to the controller 20 to provide sensing information.

When the solenoid valve or the high-level sensor 60 malfunctions, the gate valve 101 of the water supply pipe 80 must be locked with a signal from the dangerous level sensor 65 before the water in the storage tank 10 overflows.

The present invention constitutes a gate valve unit (100) including a gate valve (101) in a water pipe (80). The gate valve unit 100 receives the information of the dangerous level sensor 65 from the control unit 20 and supplies a control signal to the gate valve unit 100 when it is determined that there is a risk of water overflow, Lock it.

In order to apply this system to the installed system, it should be applicable to the various gate valves 101 and water pipes 80 installed.

Figure 2 is a representation of various gate valves. A ball valve capable of opening and closing the valve by 90 degrees, an external screw valve for opening and closing the valve, and anna valve. The amount of rotation for opening and closing the valve also varies. In order to control the valves automatically by installing them on these various valves and pipes, the separate gate valve unit 100 must have a special structure and control method.

3 is an embodiment of the gate valve portion 100. As shown in FIG. A gate valve 101 is constituted by a flange 103 on a pipe 104 located at the front and rear of the gate valve among the water supply piping 80 and a handle 102 for controlling the opening and closing of the gate valve 101 is formed. Up to this point is the structure of the gate valve 101 which is normally installed in a building. The present embodiment is a structure in which the handle 102 is rotated and opened.

The handle has a circular perimeter as the handle of the valve of FIG. 2, and has 3 to 5 handle supports for holding the handle towards the center. In the center, there is a fixing member for fixing the handle to the shaft at the center of the valve, and the handle is fixed to the shaft by the fixing member.

To automatically rotate the handle 102, the drive lever 120 is positioned through the handle support. The driving lever 120 is coupled to the driving lever support 121. The driving lever support 121 includes a disc shaped coupling portion having a circular hole for coupling the driving lever 120 to the lower portion thereof And a cylindrical body portion connected to the coupling portion and having the same radius up to the upper portion.

The upper part of the body part is coupled to the driving device main shaft 117 of the driving device 110 so that when the driving device rotates, the driving lever supporting device 121 rotates to rotate the handle 102 to open and close.

The drive lever support 121 may be configured to be removably mounted so as to correspond to the various sizes of the handle 102. In addition, the driving lever 120 can change its shape according to the type of the handle 102, and can change its size and length.

The driver 110 may include a driver motor 111 and a driver gear box 112. The control of the driver 110 can be controlled by turning on / off the power of the driver motor 111, and can be controlled by placing a separate driver controller 116. Further, in order to check how many times the driver motor 111 rotates, the driver motor 111 may include an encoder.

The driver 110 is fixed and supported using a driver support 113, a driver fixing bolt 114, and a driver clamp 115. However, since the diameter of the pipe 104 is different, the actuator clamp 115 and the actuator support 113 are configured to be changeable. In addition, when the installation position or the like is not feasible, it is possible to configure the structure in which the angle and height of the actuator support stand 113 can be adjusted as shown in FIG.

Since the gate valve 101 is rotated only 90 degrees in the case of a ball valve, the driver motor 111 is easy to operate. However, in the case of the Anna yarn or the outer screw valve, the amount of rotation differs from one valve to another during opening and closing, so that it is necessary to control the amount of rotation. If the amount of rotation is confirmed in advance and the degree of rotation or the like is known by using the encoder and the separate control unit 116, control can be performed. However, there is a problem that the unit price becomes high.

The present invention can use only simple switch on / off control of the motor 111, and the switch fixes the micro switch 118 using the switch fixing base 118-1 (also in this case, A screw groove is formed in the body portion and a position sensing nut 119 is fixed to the body sensing portion 119. The position sensing nut 119 is provided with a lever The lever 119-1 turns on and off the micro switch 118. The drive lever support 121 is rotated by the driver 110, The position sensing nut 119 is relatively rotated and moves upward together with the lever 119-1 to control the micro switch 118 to turn off the driver 110. The lever 119- 1) can be moved up and down, but can not move left and right The movement of the lever 119-1 can be easily seen from the left and right photographs of FIG.

On the other hand, since the gate valve 101 in the machine room is a valve that hardly opens and closes, there is a problem that it rusts or does not operate properly. Therefore, when the handle 102 is rotated at the same torque in the driver 110, the valve can not be locked at a high speed or, in the worst case, the valve can not be locked. In order to solve this problem, when the torque of the driver 110 is increased, the valve may be damaged in the process of locking the valve.

In order to solve the above problems, in the present invention, when the initial actuator rotates, the torque of the actuator is increased within a predetermined angle, and when the predetermined angle is exceeded, have. The predetermined angle is preferably within about 10 degrees.

Figure 6 is another embodiment of the onset.

When the size of the handle of the gate valve is larger than a predetermined value, the drive lever may not be able to transmit the force with the handle. When the distance between the plurality of drive levers is increased, May be destroyed.

In order to solve this problem, Fig. 6 has a handle with a handle 202 including a handle gear 202-1. In addition, the driver 210 is formed in the direction of the driver support 213, that is, downward. The driving unit 210 is connected to a driving unit 221 including a driving gear 221-1. When the driving unit 210 rotates, the driving unit 221 rotates and the driving gear 221-1 The handle 202 is also rotated by the handle gear 202-1 coupled to the handle 202. [

A screw groove is formed in the body portion of the driver unit 221 as in the first embodiment, and a position sensing nut 219 is coupled to the screw groove. A lever 219-1 is formed on one side of the position sensing nut 219 so that the micro switch 218 can be turned on and off by moving the lever 219-1 up and down. The operation of the position sensing nut 219 and the lever 219-1 is the same as in the first embodiment.

The micro switch 218 is fixed by a switch fixing base 218-1.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, Those skilled in the art will appreciate that various modifications and changes may be made thereto without departing from the scope of the present invention.
