Description

Technology Field

[0001] The present invention relates to an intelligent integrated control monitoring-based solar power generation device capable of pre-detecting fires and abnormal signs, and more specifically, to an intelligent integrated control monitoring-based solar power generation device capable of pre-detecting fires and abnormal signs, which can suppress fires using a multi-fire suppression method in the event of a fire in a junction box—which accounts for a high proportion of fire incidents—and capable of an integrated control system for all set areas. Background Technology

[0003] In the case of power distribution panels or junction boxes, which are part of the electrical equipment, there is a high risk of electrical fires occurring due to phenomena caused by electrical leakage, sparks, or insulation breakdown.

[0004] Furthermore, in the event of a fire in spaces such as distribution panels or junction boxes, managers typically fail to notice the fire in unmanned solar power systems. This is because there is a complete lack of fire monitoring capabilities. Even if a fire is detected via a sensor, fire suppression is difficult due to the absence of fire extinguishing devices, and in most cases, it is impossible to verify whether such devices are operational.

[0005] In addition, when the manager identifies the space where the fire occurred, they enter the space or manually extinguish the fire using fire extinguishers, etc., while the space is open.

[0006] However, in this case, there is a problem in that there is a high risk of casualties, such as electric shock caused by internal insulation breakdown or ground faults when a firefighter comes into contact with the outside of a metal enclosure.

[0007] In addition, if you touch or open the fire area without checking its internal condition, you may suffer burns from the heat and direct exposure to toxic gases.

[0008] To solve these problems, fire extinguishing devices made of thermoplastic resin on the surface have been installed, but due to the nature of being installed outdoors, the surface corrodes due to frequent temperature changes, and the fire extinguishing agent leaks into micro-spaces, failing to perform its normal function in the event of a fire.

[0009] Due to the heat-reactive surface, it cannot be displayed on monitoring systems such as separate fire extinguisher operation notifications, making it impossible to verify normal operation; this presents a problem where the status must be checked by visiting the site.

[0010] Although fires are detected through various methods such as arc generation and smoke detection in DC lines, physical methods to suppress fires are not applied due to the characteristics of DC.

[0011] At the same time, since there is no configuration for managing all solar power installation sites from a remote or virtual control power plant, real-time on-site verification of each location is unavoidable, leading to a growing problem of requiring a large workforce and demanding specialized expertise.

[0015] In addition, the present invention aims to provide an intelligent integrated control monitoring-based solar power generation device that can cut off the power system through the prior detection of fire and abnormal signs, rapidly operate a fire extinguishing device regardless of whether the fire-affected space is open or entered, and improve safety by avoiding direct contact with the enclosure.

[0027] The intelligent integrated control monitoring-based solar power generation device capable of pre-detecting fire and abnormal signs according to the present invention has the effect of minimizing casualties and property damage by applying a triple operation method of automatic fire extinguishing of a built-in automatic fire extinguishing device instead of the extrusion spray method of a general fire extinguisher when a fire occurs, thereby enabling fire suppression in the detection section before fire, the initial section of fire, and the rapidly rising section of fire, thereby improving safety and reducing fire suppression time.

Specific details for implementing the invention

[0034] Terms and words used in this specification and claims should not be interpreted as being limited to their ordinary or dictionary meanings, and should be interpreted in a meaning and concept consistent with the technical spirit of the invention, based on the principle that the inventor can appropriately define the concept of the terms to best describe his invention.

[0035] Therefore, the embodiments described in this specification and the configurations illustrated in the drawings are merely one preferred embodiment of the present invention and do not represent all of the technical ideas of the present invention; thus, it should be understood that various equivalents and modifications that can replace them may exist at the time of filing this application.

[0036] Hereinafter, an intelligent integrated control monitoring-based solar power generation device capable of pre-detecting fire and abnormal signs according to the present invention will be described in more detail with reference to the attached drawings.

[0037] FIG. 1 is a configuration diagram of an intelligent integrated control monitoring-based solar power generation device capable of pre-detecting fire and abnormal signs according to the present invention.

[0038] As illustrated in FIG. 1, the intelligent integrated control monitoring-based solar power generation device capable of pre-detecting fire and abnormal signs according to the present invention includes a solar module (100), a module power cutoff box (200), a fire cutoff connection box (300), a power converter (400), a power distribution board (500), an RTU (Remote Terminal Unit: 600), and a monitoring system (700).

[0039] The above solar module (100) is a power generation module formed by connecting multiple 'solar cells' in series or parallel and sealing them with a frame and protective material to form a single rigid plate, which directly converts solar energy into electrical energy.

[0040] The above module power cutoff box (200) is a core electrical protection device of a photovoltaic power generation system that detects and manages power supplied from the above solar module (100) or string (module combination) in real time, and immediately cuts off the circuit for each string when a dangerous situation such as overload, short circuit, abnormal current, or fire occurs, thereby ensuring the safety of the system and the user.

[0041] That is, the module power cutoff box (200) is formed between the solar module (100) and the fire cutoff junction box (300), and when an abnormality such as overcurrent, short circuit, or fire is detected, it quickly and safely cuts off the power between the solar module (100) and the fire cutoff junction box (300) to prevent arc generation or additional damage.

[0042] As shown in FIG. 2, only the positive (+) terminal of the solar module (100) is connected to the circuit breaker of the module power cutoff box (200) and then connected to the fire cutoff connection box (300). In a state where the negative (-) terminal of the solar module (100) is directly connected to the fire cutoff connection box (300), a temperature sensor is installed inside the fire cutoff connection box (300) to detect operation in case of fire and high temperature in the module power cutoff box (200).

[0043] The above module power cutoff box (200) has an individual cutoff function by tripping the cutoff switch for each string when a bimetal switch detects a fire in the above fire cutoff connection box (300) to ensure safe access.

[0044] The above fire cutoff junction box (300) interconnects the sensor, control, communication, and cutoff functions with the above module power cutoff box (200) to protect the system's power flow and the entire facility, including modules, junction boxes, and wiring, in real time.

[0045] More specifically, the fire cutoff connection box (300) includes an early fire extinguishing operation device (310), a visualization device (320), a gas-type automatic fire extinguishing device (330), a sensor module (340), an intelligent computing device (350), a main power cutoff device (360), and a string power monitoring device (370), as shown in FIG. 3.

[0046] The above early fire extinguishing device (310) is a device that allows the fire extinguishing device installed inside to be forcibly operated safely through manual operation without contact with the outer casing when a fire occurs.

[0047] When a fire occurs, if the wiring inside the fire-blocking connection box (300) comes into contact with the outer casing from the inside, current is applied to the outer casing in a single-line ground fault state (single-line ground fault), and if a user touches the outer casing to open the door of the outer casing for the purpose of fire suppression, an electric shock accident may occur, and if the user touches the outer casing heated by the fire, burns may occur.

[0048] Accordingly, the above-mentioned early fire extinguishing device (310) has an operating part formed externally so that a user can manually operate it from outside the fire blocking connection box (300), and a fire extinguishing device formed inside the outer box.

[0049] More specifically, as illustrated in FIG. 4, the early fire suppression device (310) includes an operating part (311), an operating part (312), and a suppression part (313).

[0050] The above operating part (311) can be operated by the user by opening the cover (311a) formed on the outside of the outer casing installed for arbitrary operation and waterproofing of the fire cutoff connection box (300) and pulling the operating lever (311b).

[0051] The above operating unit (312) transmits the operating power generated by the user pulling the operating lever (311b) of the above operating unit (311) to the above suppression unit (313) so that the corresponding suppression unit (313) can operate.

[0052] More specifically, the operating part (312) includes a return elastic body (312a) and a power transmission wire (312b).

[0053] One end of the above-mentioned return elastic body (312a) is connected to the operating lever (311b) and the other end is fixed inside, so that it expands when the operating lever (311b) is pulled and returns to its original state when the pull is released.

[0054] The above return elastic body (312a) improves operation performance by enabling re-operation by automatically returning the above operation lever (311b) in the event of a misoperation.

[0055] One end of the power transmission wire (312b) is connected to the operating lever (311b), and the other end is connected to the glass bulb (313a) of the suppression unit (313), so that the glass bulb (313) is ruptured as the user pulls the operating lever (311b).

[0056] The glass bulb (313a) is a heat-sensitive element, and when it reaches a specific temperature, the internal liquid expands, causing the glass bulb to break and release extinguishing water into the extinguishing tank (313b). However, the user pulls the operating lever (311b) before the specific temperature is reached to spray the extinguishing liquid from the extinguishing tank (313b) early. The glass bulb (313a) is a sub-component constituting the suppression unit (313).

[0057] As mentioned above, the suppression unit (313) is composed of a glass bulb (313a) and a fire extinguishing tank (313b), and as the glass bulb (313a) formed at the inlet of the fire extinguishing tank (313b) containing the fire extinguishing liquid is ruptured as described above, the fire extinguishing liquid inside the fire extinguishing tank (313b) is sprayed to suppress the fire.

[0058] The above visualization device (320) displays the conditions inside the fire-blocking connection box (300) in different colors, such as normal power generation, circuit breaker inspection, and fire, so that they can be known from the outside.

[0059] The above visualization device (320) ensures optimal identification performance by applying high-efficiency LEDs.

[0060] The above gas-type automatic fire extinguishing device (330) is a fire extinguishing device capable of mechanical or electrical operation, normally stored in a liquid state, and vaporizes into a colorless and odorless vapor when sprayed, leaving no residue.

[0061] For reference, the gas-type automatic fire extinguishing device (330) may be identical to the suppression unit (313), and the glass bulb (313a) may correspond to the heat detection device (331).

[0062] First, the mechanism by which the gas-type automatic fire extinguishing device (330) operates mechanically to operate the fire extinguishing device will be explained.

[0063] More specifically, the gas-type automatic fire extinguishing device (330) includes a heat detection device (331), a fixing pin (332), a first pressure spring (333), a latch (334), a latch support shaft (335), a movable frame (336), a second pressure spring (337), and a projection (338), as shown in FIG. 5.

[0064] As shown in FIG. 5b, the heat detection device (331) expands and ruptures when it reaches a specific temperature.

[0065] The above fixing pin (332) moves upward as the heat sensing device (331) ruptures.

[0066] The first pressure spring (333) is stretched as the heat sensing device (331) ruptures, and the tension generated helps the fixing pin (332) move upward as shown in FIG. 5b.

[0067] One end of the latch (334) is fixed to the fixing pin (332), and the other end is hooked onto the projection (338) that is holding the movable frame (336).

[0068] The above latch support shaft (335) is formed in a vertical direction and supports the middle point of the latch (334) so ​​that it can rotate with a seesaw mechanism.

[0069] The above-mentioned movable frame (336) is composed of a vertical frame (336a) and a horizontal frame (336b) in an L-shape structure and is movable according to the rotation of the above-mentioned latch (334).

[0070] The second pressure spring (337) is formed on the outer surface of the vertical frame (336a) and provides elastic force to move downward as the latch (334) releases the pressure of the projection (338) that is fixing the vertical frame (336a).

[0071] That is, the second pressure spring (337) causes the vertical frame (336) to move downward by the tension force generated as the pressure of the projection (338) is released.

[0072] As the above projection (338) releases contact with the other end of the latch (334) it is in contact with, it releases the movement of the vertical frame (336a).

[0073] As described above, as the vertical frame (336a) moves, the combined horizontal frame (336b) moves downward and pressurizes the valve (V) of the fire extinguishing tank (313b) as shown in FIG. 5b to spray the fire extinguishing liquid.

[0074] The above gas-type automatic fire extinguishing device (330) may also spray fire extinguishing liquid by pressurizing the valve of the fire extinguishing tank (313b) through electrical operation.

[0075] As illustrated in FIG. 6c, by detecting early fire and local fire through smoke, infrared, and heat detection via the CO or IR detection sensor (341) and temperature sensor (342) of the sensor module (340), the intelligent computing device (350), which receives the detection information of the CO or IR detection sensor (341) and temperature sensor (342) via wired or wireless connection, operates the gas-type automatic fire extinguishing device (330).

[0076] That is, as the intelligent computing device (350) applies power to the solenoid (339), the plunger (P) is pulled downward and pressurizes the latch (334), and the latch (334) rotates under the support of the latch support shaft (335) to operate the operating device (336), thereby mechanically operating the gas-type automatic fire extinguishing device (330), and the horizontal frame (339b) pressurizes the valve (V) of the fire extinguishing tank (313b), which is not shown in FIG. 6, to spray the fire extinguishing liquid.

[0077] At this time, it is preferable that a return spring (339a) formed in a compressed state on the outer surface of the plunger (P) is tensioned together with the plunger (P) moving downward when power is applied and the solenoid (339) is operated, and when power is cut off, it is compressed back to its original state to return the plunger (P) to its original position.

[0078] As described above, the gas-type automatic fire extinguishing device (330) is described in cases where it operates mechanically and electrically, but as shown in FIG. 7, the overall mechanism is similar, except that the power source that operates the latch (334) to operate the movable frame (336) is different.

[0079] The sensor module (340) may further include a humidity sensor (343) to measure the humidity inside the fire-blocking connection box (300).

[0080] Before a fire occurs, the temperature sensor (342) measures the temperature inside the fire cutoff connection box (300), and the intelligent computing device (350) connected to the temperature sensor (342) can indicate a fire warning as 'high temperature' if the measured value (sensor) is greater than or equal to the set value (setting).

[0081] Additionally, when the CO or IR detection sensor (341) measures the carbon monoxide concentration inside the fire cutoff connection box (300) in real time, the intelligent computing device (350) displays a monitoring fire warning if the measured carbon monoxide concentration is above the lower limit of the set range, and when the carbon monoxide concentration persists within the lower and upper limits of the set range for a certain period of time, it activates the main power cutoff device (360) to cut off the main power supply.

[0082] At this time, if the carbon monoxide concentration exceeds the upper limit of the set range for a certain period of time or longer, it is preferable for the user to first operate the early fire suppression device to activate the suppression unit (313) or the gas-type automatic fire suppression device (330).

[0083] If primary extinguishing is not achieved, the gas-type automatic fire extinguishing device (330) performs secondary extinguishing by an electrical method, and if secondary extinguishing is not achieved, tertiary extinguishing is achieved by a mechanical method.

[0084] Infrared (IR) detection through the above CO or IR detection sensor (341) can further determine whether an actual fire has occurred by detecting fire flames, thereby improving reliability.

[0085] If the above CO or IR detection sensor (341) does not detect both carbon monoxide and infrared radiation within the set range, or detects only one of carbon monoxide and infrared radiation, it does not perform warning indication, main power supply cutoff, or fire extinguisher operation output.

[0086] On the other hand, if the CO or IR detection sensor (341) detects both carbon monoxide and infrared radiation within the set range, it performs a warning indication, cuts off the main power supply, or outputs the operation of a fire extinguishing device.

[0087] CO IR output of power 0 0 0 1 0 0 0 1 0 1 1 1

[0088] However, if the above carbon monoxide concentration exceeds the upper limit of the set range for a certain period of time or longer, the fire cutoff connection box (300) performs a warning indication, cutoff of main power supply, or operation of a fire extinguishing device regardless of the detection of CO and IR.

[0089] Immediately after a fire occurs, when a local fire starts in the fire cutoff connection box (300), the CO or IR detection sensor (341) measures the CO concentration and measures the time.

[0090] When power is supplied, the above-mentioned early fire extinguishing device (310) is operated to activate the suppression unit (313) so that the fire can be suppressed early.

[0091] When the power supply is cut off due to the occurrence of a direct fire, such as a large fire (flame) or a DC electric fire inside the fire-blocking connection box (300), the heat detection device (331) is activated and ruptured, causing the gas-type automatic fire extinguishing device (330) to operate, thereby allowing the fire to be quickly suppressed.

[0092] Alternatively, if a fire suppressor detects a fire near the fire cutoff connection box (300), the early fire suppression activation device (310) is operated to forcibly activate the suppression unit (313) so that forced fire suppression can be carried out.

[0093] As mentioned above, the intelligent computing device (350) receives detection information from the CO or IR detection sensor (341) and temperature sensor (342) connected via wired or wireless connection.

[0094] More specifically, as shown in FIG. 8, the intelligent computing device (350) is equipped with a control power connection unit, a sensor module connection unit, a status notification display connection unit, an RS485 communication connection unit, and a voltage and current measurement unit for each string, and performs the functions of monitoring the voltage and current for each string of the photovoltaic power generation device, monitoring the internal temperature of the junction box, displaying a high temperature when the temperature is above the set temperature, and displaying a status notification (Red_R, Blue_B, Green_G) inside the junction box.

[0095] The intelligent computing device (350) may operate the gas-type automatic fire extinguishing device (330) as described above with the received detection information, but may also transmit the detection information to the monitoring system (700) located locally or remotely via wired or wireless so that an administrator or others can monitor it locally or remotely, and may also transmit information such as voice and lamp notification output.

[0096] The above monitoring system (700) can monitor and control N multiple locations from one place through wired or wireless fire monitoring, thereby reducing manpower waste, improving safety through remote control upon early detection of abnormal conditions, and increasing maintenance efficiency thereafter.
