In order to fully understand the present invention, preferred embodiments of the present invention will be described with reference to the accompanying drawings. Embodiments of the present invention may be modified in various forms, and the scope of the present invention should not be construed as being limited to the examples described in detail below. This embodiment is provided to more completely explain the present invention to those skilled in the art. Therefore, the shapes of elements in the drawings may be exaggerated to emphasize a clearer description. It should be noted that in each drawing, the same members are sometimes indicated by the same reference numerals.

A switchboard equipped with a disaster warning system according to the present invention (hereinafter, referred to as a switchboard) includes a main body 10, a sensor unit 30, an alarm unit 20, and a control unit 40, as shown in FIG. can be defined as

A plurality of power distribution devices 1 for power distribution may be embedded in the main body 10, and may be formed in the form of an enclosure made of a solid metal material so that external factors do not act on the power distribution devices 1 built in. (1) It is preferable to be formed to have a predetermined extra space to minimize direct contact with.

In one embodiment, the main body 10 may be provided in the form of a square enclosure, that is, in the form of a hexahedron, and a door capable of opening and closing may be formed on the front side. Also, a control switch of the power distribution device 1 may be formed on the door.

The door is always locked to prevent unauthorized third party access and safety accidents, but is designed to be opened in a way that only the manager knows. For example, it may include a structure in which only an administrator can open and close it through a secret key or a locking device.

A display window may be formed on the door to check whether the power distribution device 1 installed inside the main body 10 operates normally, and a manager can check the internal situation through the display window without opening the door. Therefore, if it is not a situation in which the power distribution device 1 must be directly manipulated by entering through the door, it can be easily checked through the display window.

Other specific structures of the main body 10 will be described later.

Next, the sensor unit 30 is installed on the main body 10 and generates a disaster signal by detecting a nearby disaster. Here, a disaster is a concept including fire, earthquake, flood, etc., and means a situation that causes a failure of the power distribution device 1. When such a disaster situation occurs, the sensor unit 30 quickly senses it and It enables early response to prevent accidents in advance.

The sensor unit 30 measures the temperature inside the main body 10 and generates a temperature signal when the measured temperature turns around a preset critical temperature, and detects an overcurrent of the power distribution device 1 An overcurrent sensor 32 that generates an overcurrent signal, a fire sensor 33 that generates a fire signal when a fire inside or outside the body 10 is detected, and an earthquake sensor 34 that detects an earthquake may be included.

The temperature sensor 31 may be installed inside the main body 10 and, in particular, is disposed close to the power distribution device 1 to detect heat generated from the power distribution device 1 .

The temperature sensor 31 may measure and sense the operating temperature of the power distribution device 1, that is, the amount of heat generated by the power distribution device 1 in real time.

The temperature sensor 31 is divided into a contact type for temperature sensing by direct contact and a non-contact type for measuring radiated heat rays. Here, the temperature sensor 31 includes a thermistor, a thermocouple, a thermocouple, a crystal oscillator, a pyroelectric infrared sensor, an IC temperature sensor, a transistor, a photoelectric tube, a diode, a photodiode, a phototransistor, a shape memory alloy (SMA), and a thermosensitive ferrite. , mercury thermometers, quantum infrared sensors, etc. can be used.

The temperature sensor 31 compares the detected temperature in real time with a predetermined threshold temperature, and sends a temperature signal to the control unit 40 when the temperature exceeds the threshold temperature.

Next, the overcurrent sensor 32 measures the current flowing through the power distribution device 1 and measures an abnormal overcurrent excessively flowing due to a short circuit or a short circuit, and various configurations are possible. For example, the overcurrent sensor 32 may be one or more current measurement sensors that measure the current flowing through the power distribution device 1 in real time.

The overcurrent sensor 32 transmits an overcurrent signal to the control unit 40 when overcurrent is detected.

Next, the fire sensor 33 is a line capable of detecting a fire occurring around the power distribution device 1 according to overheating, short circuit, short circuit, or arc generation of the power distribution device 1, for example, a smoke sensor, flame It may be composed of a detection sensor, a gas detection sensor, and the like.

The smoke detection sensor and the flame detection sensor send a fire signal to the controller 40 when smoke or flame is detected.

The smoke detection sensor and the flame detection sensor generally use an optical sensor, and generate signals by measuring the amount of light emitted by the flame, the shape or state of the flame, the movement of the flame, or the movement of smoke. The smoke detection sensor and the flame detection sensor can convert the light itself or the information contained in the light into an electrical signal using photoelectric conversion principles such as photoelectric effect, photoconductive effect, photovoltaic effect, and pyroelectric effect. A photodiode, phototransistor, LASCR, CCD image sensor, MOS image sensor, photothyristor, photoelectric power tube, photoelectric tube, photocoupler, color sensor, PSD, fiber sensor, infrared sensor, ultraviolet sensor, etc. may be used.

The gas detection sensor measures the components of the gas and detects a fire by a specific amount of gas components. In this embodiment, it is assumed that carbon monoxide, carbon dioxide, etc. are measured and described, but is not limited thereto, and the combustion process of surrounding structures in the event of a fire It is possible to detect the occurrence of a fire by detecting any one of the noxious gases generated from the gas.

Here, there are various types of gas detection sensors depending on the type of gas and the gas concentration. Generally, it is composed of catalytic combustion sensors, semiconductor sensors, ceramic gas sensors, etc., and includes electrochemical methods (solution conduction method, potentiostatic electrolysis method, diaphragm approach), optical methods (infrared absorption method, visible part absorption method, optical interference method). method), electrical methods (hydrogen ionization method, thermal conduction method, catalytic combustion method, semiconductor method) gas chromatography method, etc. may be used.

Next, when an earthquake occurs, the earthquake sensor 34 senses it, generates an earthquake signal, and transmits it to the control unit 40 . Since the earthquake sensor 34 may use a known sensor capable of detecting vibration caused by an earthquake, a detailed description thereof will be omitted.

Each signal generated by the smoke detection sensor, flame detection sensor, and gas detection sensor is integrated into a fire signal, and the temperature signal of the temperature sensor 31, the overcurrent signal of the overcurrent sensor 32, and the earthquake of the earthquake sensor 34 The fire signal of the signal and fire sensor 33 may be integrated into a disaster signal and transmitted to the control unit 40 .

Next, the control unit 40 is responsible for controlling the operation of the warning unit 20 based on the disaster signal.

That is, the control unit 40 is electrically connected to the sensor unit 30 and receives a signal generated from the sensor unit 30, and operates the alarm unit 20 based on this, so that an alarm can be output to the outside. .

At this time, since the alarm unit 20 is installed on the outside of the main body 10 and can output an alarm, for example, an alarm sound or an alarm light to the outside, a known siren structure can be used, so a detailed description thereof will be omitted.

On the other hand, upon receiving the disaster signal, the control unit 40 may determine that a disaster has occurred in the switchboard, especially a fire in the case of a fire signal. Accordingly, it may automatically cut off power in the switchboard or receive a fire report. there is. To this end, the control unit 40 may be connected to the fire reporting module, and the fire reporting module is operated according to the control signal of the control unit 40 to automatically receive a fire report to the disaster handling agency 50a, for example, 119. .

The fire reporting module may use an automatic reporting device. Such an automatic reporting device can be set in advance to automatically report a fire to a nearby 119 upon receiving a control signal from the control unit 40 . In the case of a fire accident, it is most important to respond quickly at the beginning. If a fire breaks out while the manager of the switchboard is away, it may develop into a serious accident because immediate response is impossible.

The control unit 40 may include a communication unit for communication with an external device so as to transmit the temperature of the power distribution device 1 measured by the sensor unit 30, an operating state, whether a disaster has occurred, etc. to the manager terminal 50. there is.

The communication unit is connected to the control unit 40 by wire, and receives information provided from the control unit 40 along the connected wire. In addition, the received information may be transmitted to the manager terminal 50 wirelessly.

The communication unit may be separated from the control unit 40 and connected by wire in preparation for the possibility of being affected by the high voltage or high current generated in the power distribution device 1 .

In transmitting various types of information wirelessly, the communication unit uses a predetermined wireless communication network. For example, Wi-Fi, 3G or 4G networks may be used. The manager terminal 50 has the same concept as a manager's smart phone, and can receive switchboard state information through such a wireless communication network.

Meanwhile, the communication unit may transmit the operating state of the power distribution device 1 displayed on the display window to the manager terminal 50 .

As an embodiment, the manager terminal 50 determines whether the power distribution device 1 is operating normally through the communication unit, whether a fire has occurred in the power distribution device 1, or how many degrees the operating temperature of the power distribution device 1 is. recognition can be verified. In order to check these contents, an application communicating with a communication unit may be installed in the manager terminal 50 .

Therefore, even if the manager of the switchboard is away from the site, it is possible to immediately cope with a fire accident, and the advantage of being able to check the state of the power distribution device 1 from a remote location using the manager terminal 50 is provided.

Hereinafter, a specific structure of the main body 10 will be described with reference to the accompanying drawings.

As shown in FIGS. 3 to 5, the main body 10 includes an outer housing 11, an inner housing 12, a pressure protrusion 13, an elastic pad 14, a pressure sensor 15, and a floating motor 16. ), it may be illustrated as including a rotary drum 17 and a buoyancy wire 18.

The outer housing 11 constitutes the outermost part of the main body 10 and may be formed in the form of a rectangular enclosure forming a rocking space 11a therein. The door, display window, etc. may be provided in the outer housing 11 , and the alarm unit 20 may be installed at an appropriate place on the upper surface of the outer housing 11 .

Next, the inner housing 12 is configured to be accommodated in the swinging space 11a of the outer housing 11, and is seated and accommodated on the bottom surface of the swinging space 11a, and the inner wall surface of the swinging space 11a. It may be formed in the form of a rectangular enclosure configured to offset a certain distance from the upper surface toward the inside.

That is, the inner housing 12 may be provided in the form of an enclosure having a smaller size than the inner size of the outer housing 11 and spaced apart from the inner surface and upper surface of the swinging space 11a by a predetermined distance.

The inner surface, the bottom surface, and the top surface of the swinging space 11a may refer to an inner side surface, an inner bottom surface, and an inner top surface of the inner space of the outer housing 11, respectively.

Again, a caster 12a supported by rolling on the bottom surface of the swinging space 11a may be provided at the lower part of the inner housing 12, and thus, the inner housing 12 may be provided with vibration caused by an earthquake in the main body ( 10), a structure capable of eccentric movement in the forward, backward, left and right directions inside the swinging space 11a is provided.

As the inner housing 12 moves, the elastic pad 14 to be described later may be pressed with a certain pressure. That is, when vibration caused by an earthquake occurs, the inner housing 12 vibrates in an irregular direction within the shaking space 11a to press the elastic pad 14 .

The power distribution device 1 may be embedded in the inner housing 12 , and a door may be provided to open and close the inside like the outer housing 11 .

Next, the pressing protrusion 13 is configured to protrude from each side of the inner housing 12, and protrudes toward the inner surface of the swing space 11a from each side of the inner housing 12 in the form of a square housing. It can be made in the form of four protrusions.

Next, the elastic pad 14 is formed on the inner surface of the swinging space 11a facing the pressing protrusion 13 and is supported in contact with each of the pressing protrusions 13 at corresponding locations, and the pressure protrusion 13 Similarly, on the inner surface of each swinging space 11a, it is formed in the form of a protrusion protruding toward the facing pressing protrusion 13.

In the state in which the inner housing 12 is seated and supported on the bottom surface of the swinging space 11a, each of the pressing protrusions 13 formed on the inner housing 12 is in contact with the elastic pad 14, while FIG. 9 As shown in , when the inner housing 12 moves upward, the pressure protrusion 13 may be spaced upward from the elastic pad 14 accordingly.

The elastic pad 14 is preferably made of a material such as silicon, rubber, etc., which has a predetermined elastic force and can buffer the shock applied from the contact-supported inner housing 12 or restore it to its original state.

In particular, when the lateral pressure is applied by the pressure protrusion 13 as the inner housing 12 vibrates, the elastic pad 14 is compressed and deformed in a certain shape accordingly, and then returns to its original state when the lateral pressure is removed. can be restored with

The elastic pad 14 has an empty interior, and a pressure sensor 15 to be described below may be installed in the empty space.

Next, the pressure sensor 15 is built into the elastic pad 14 and generates a vibration signal as the elastic pad 14 is compressed and deformed, and the generated vibration signal is sent to the control unit 40, and the control unit 40) controls the operation of the support motor 16 to be described later based on the vibration signal.

The pressure sensor 15 includes, for example, a first conductor 15a and a second conductor 15b spaced apart from each other at a predetermined distance inside the elastic pad 14, and the first conductor ( 15a) and the second conductor 15b are respectively connected to apply current, and when the first conductor 15a and the second conductor 15b come into contact with each other to form a contact point, when current flows, it is sensed and a vibration signal is generated. It can be illustrated as including a detector (not shown) that does.

That is, as shown in FIG. 8, when the first conductor 15a and the second conductor 15b embedded in the elastic pad 14 come into contact with each other by compression deformation of the elastic pad 14, the detector This is the principle of generating a vibration signal and sending it to the control unit 40.

Next, the lifting motor 16 is configured to generate power for lifting the inner housing 12 to a certain height in the lifting space, is installed on the upper surface of the outer housing 11, and is operated and controlled based on the vibration signal. can

That is, when the vibration signal is transmitted, the control unit 40 operates the lifting motor 16 to lift the inner housing 12 to a certain height.

The rotary drum 17 is coupled to the rotary shaft of the lift motor 16, so that it can rotate in the forward and reverse directions. A lift wire 18, which will be described later, is connected to the rotary drum 17, so that the lift wire 18 can be wound or unwound.

Next, the lifting wire 18 has one end connected to the inner housing 12 and the other end connected to the rotary drum 17, and the rotary drum by connecting the inner housing 12 to the rotary drum 17 ( As the 17) rotates, when the buoyancy wire 18 is wound around the outside of the rotary drum 17, the inner housing 12 can be buoyed upward at a certain height.

At this time, the buoyancy wire 18 consists of at least 4 pieces so that they can be connected to each corner of the upper surface of the inner housing 12, while in the case of the outer housing 11, each buoyancy wire 18 is not interfered with. In order not to do so, the outer housing 11 has a structure in which four passage holes 11b through which each of the lifting wires 18 pass are formed through the corner portion of the upper surface.

Meanwhile, the rotary drum 17 may be disposed at the top center of the outer housing 11, and four buoyancy wires 18 extend radially from the rotary drum 17 to form respective through holes 11b. It can be inserted into and connected to the upper surface of the inner housing 12.

Accordingly, one end of each buoyancy wire 18 radially converges toward the rotary drum 17 while being connected to each corner of the upper surface of the inner housing 12, and the other end is connected to the rotary drum 17. It is made of a structure so that when the inner housing 12 is lifted, it does not lose its balance, and the lifting operation can be performed stably, and even after the inner housing 12 is lifted to a certain height, it randomly rotates or It provides the advantage of being able to have a stable posture by effectively suppressing movement.

On the other hand, a plurality of guide rollers 11c for guiding each of the support wires 18 exposed to the upper portion of the outer housing 11 through the passage holes 11b around each of the plurality of passage holes 11b. can be installed.

That is, each of the buoyancy wires 18 exposed through the passage hole 11b is guided by each guide roller 11c and more stably wound or unwound around the rotary drum 17 while maintaining a constant tension and direction. operation can be made.

On the other hand, in the section between the upper surface of the inner housing 12 and the guide roller 11c, each of the lift wires 18 is operated in a straight line perpendicular to the upper surface of the inner housing 12. is equipped

In other words, the buoyancy wire 18 extending from the upper surface of the inner housing 12 is exposed through the passage hole 11b and operates in a straight line until guided by the guide roller 11c disposed directly above it. By doing so, irregular twisting or unnecessary interference between the outer housing 11 and the inner housing 12 is prevented.

When the vibration caused by an earthquake is applied to the switchboard, the main body 10 having such a structure lifts the inner housing 12 within the outer housing 11 to a certain height in the swinging space 11a, so that the vibration caused by the earthquake is applied to the inner housing It is not transmitted to the power distribution device 1 accommodated in (12).

That is, when the outer housing 11 vibrates due to the occurrence of an earthquake, this vibration is transmitted to the inner housing 12 in contact with the elastic pad 14 of the outer housing 11, and the inner housing 12 rotates in all directions. On the other hand, as vibration is applied to the inner housing 12 in this process, the inner housing 12 moves eccentrically in the swinging space 11a and the pressing protrusion 13 presses the elastic pad 14 , A vibration signal is generated by compression deformation of the elastic pad 14 and is transmitted to the control unit 40.

Accordingly, the controller 40 controls the operation of the lift motor 16 based on the vibration signal, while the rotary drum 17 is rotated by the lift motor 16 and the lift wire 18 is wound around the lift wire 18 to the outside. As the inner housing 12 connected to the wire 18 is lifted upward in the floating space at a predetermined height, the side surface and lower surface of the inner housing 12 are suspended at a predetermined distance from the side surface and lower surface of the floating space.

When the inner housing 12 floats and hangs in this way, the pressure protrusion 13 is also separated from the elastic pad 14 in the vertical direction, so that the generation of the vibration signal is stopped, while the inner housing 12 ) can remain suspended.

That is, when an earthquake occurs, the main body 10 completely separates the inner housing 12 from the outer housing 11 to suppress transmission of vibration to the power distribution device 1, but in particular, the inner housing 12 is a buoyancy wire Only by (18), it becomes suspended inside the outer housing 11, so that even if the outer housing 11 vibrates vertically or horizontally, this vibration is not easily transmitted to the inner housing 12. In addition, even if the inner housing 12 vibrates, it has a structure that does not easily collide with the outer housing 11.

As a result, a safety structure in which the power distribution device 1 housed in the inner housing 12 can be more effectively protected from vibration is provided.

The embodiments of the present invention described above are merely exemplary, and those skilled in the art will appreciate that various modifications and equivalent other embodiments are possible therefrom. Therefore, it will be well understood that the present invention is not limited to the forms mentioned in the detailed description above. Therefore, the true technical protection scope of the present invention should be determined by the technical spirit of the appended claims.
