Description

Technology Field

[0001] The present invention relates to a panel for piping facilities in a building, and more specifically, to a modular PD (Pipe Duct) fire hydrant panel that can be assembled and installed on-site using a dry construction method and allows for easy replacement of the fire hydrant installed inside. Background Technology

[0002] In general, fire hydrants are mandatory in buildings such as apartments and commercial buildings to facilitate initial fire suppression. For aesthetic reasons and space efficiency, these fire hydrant systems are installed by being embedded within pipe ducts provided inside the walls, typically within PDs.

[0003] Conventional buried PD and fire hydrant structures were complex work processes and were a major factor in delaying the overall construction period. Furthermore, finishing quality varied significantly depending on the skill level of the workers, and the construction process generated large amounts of dust, noise, and construction waste, which compromised the working environment and caused environmental pollution.

[0004] Furthermore, conventional structures posed serious problems regarding the maintenance of fire hydrant systems. When a fire hydrant valve needed replacement due to failure or aging, fixed walls had to be demolished to access the hydrant inside. This process not only incurred significant costs and time but also caused great inconvenience to residents and building users due to the noise and dust generated during the demolition. Even after the replacement was completed, additional plastering and painting work was required to restore the damaged walls, resulting in extremely low maintenance efficiency. The problem to be solved

[0005] The present invention was devised to solve the above-mentioned problems, and the objective of the present invention is to provide a modular fire hydrant panel that drastically shortens the construction period, ensures uniform construction quality, and minimizes the generation of dust and waste at the construction site by applying a dry construction method in which standardized modules pre-fabricated in a factory are mechanically assembled at the site.

[0006] The purpose is to provide a modular fire hydrant panel that maximizes the convenience and safety of maintenance work by automatically ejecting the fire hydrant to an easy-to-work position in front of the panel via an internal mechanical drive unit without damaging the wall when repair or replacement of the fire hydrant is required.

[0007] The invention provides a modular fire hydrant panel that improves the structural stability and reliability of fire extinguishing equipment under normal conditions by determining and maintaining whether the fire hydrant is accurately and securely fixed in the correct position through mechanical locking devices and sensors.

[0020] The driving force of the above motor (280) rotates the disk shaft (211) through the gear section to rotate the support head (230), and is characterized by

[0021] A plurality of adjustment grooves (212) formed on the circumferential surface of the above-mentioned rotating disk (210); and

[0022] To selectively fix the rotation of the rotating disk (210), the disk adjustment unit (300) further comprises a second adjustment frame (340) of a link structure configured such that one end is fixed to the basic frame unit (10) and the other end approaches and separates from the circumferential surface of the rotating disk (210), and a spherical fastening part (400) installed at the other end of the second adjustment frame (340) and physically inserted into or separated from one of the adjustment grooves (212).

[0041] In addition, power, power transmission, and control therefor for the following assembly configurations and embodiments, including "by control," follow conventional technology including terminals, applications, hardware control modules, etc., so they are omitted to avoid redundancy.

[0042] In addition, the operation embodiments and configurations described in a general manner without being explained in detail below follow the prior art and are omitted in order to focus on describing the purpose of the present invention and the resulting effects.

[0043] Furthermore, in describing the present invention, if it is determined that a detailed description of related known functions or configurations may unnecessarily obscure the essence of the invention, such detailed description is abbreviated or omitted.

[0044] The present invention may include a basic frame unit (10), a finishing panel unit (20), a door unit (30), a coupling unit (40), and a fire hydrant fixing unit (100).

[0045] A basic frame unit (10) according to one embodiment of the present invention is a component installed in an opening of a building wall to form the structural framework of the entire PD panel. The basic frame unit (10) may be configured to include a plurality of vertical frames (11) and horizontal frames (12) assembled on-site, and a length adjustment unit (13) capable of adjusting the length according to site conditions.

[0046] The vertical frame (11) and horizontal frame (12) are made of a metal material that is lightweight yet possesses sufficient structural strength, such as galvanized steel or lightweight structural steel. Their role is to provide reference points to which the fire hydrant fixing unit (100), finishing panel unit (20), door unit (30), etc., described later can be connected, and to support the load generated from these units and transmit it to the building structure. The vertical frame (11) and horizontal frame (12) are assembled at right angles to each other on-site by the connecting unit (40) to form a square frame.

[0047] The above length adjustment unit (13) is configured to compensate for construction errors in the site opening. This can be implemented as a telescopic structure in which the inner frame and the outer frame overlap in a sliding manner and are fixed with bolts at specific positions. The above length adjustment unit (13) is applied to a part of the horizontal frame (12) or the vertical frame (11) to allow the overall width and height of the basic frame unit (10) to be precisely adjusted in millimeters (mm) at the site.

[0048] The core functions of the above basic frame unit (10) are 'modularity' and 'on-site adaptability'. Vertical frames (11) and horizontal frames (12) of standardized lengths are pre-fabricated in a factory, and then precisely assembled on-site using the length adjustment unit (13) to match the actual size of the building opening. This is a mechanism that enables the formation of a customized structure under any site conditions. The assembled basic frame unit (10) is firmly fixed to the building wall (concrete or stud) using the above connecting unit (40), such as anchor bolts, thereby performing the function of ensuring the stability of the entire panel system.

[0049] In one embodiment, it is performed step by step as follows:

[0050] (1) Measure the width and height of the on-site PD opening.

[0051] (2) The vertical frame (11) and the horizontal frame (12), which are standardized members, are brought into the site.

[0052] (3) The length adjustment unit (13) is operated to adjust the overall size of the frame to the actual size.

[0053] (4) Using the above-mentioned connecting unit (40), the vertical frame (11) and the horizontal frame (12) are assembled to complete the square frame.

[0054] (5) Insert the completed basic frame unit (10) into the PD opening, align it horizontally and vertically, and then finally fix it to the building wall.

[0055] The finishing panel unit (20) is a panel-shaped component attached to the outside of the basic frame unit (10) to shield the PD space from the outside and form the final finishing surface of the building. The finishing panel unit (20) may include a panel body (21) and a panel joining part (22) for joining with the basic frame unit (10).

[0056] The above panel body (21) is a key part that serves as the final finishing material. Its material must satisfy the fire resistance performance required by regulations, and may be gypsum board, CRC board, or metal sheet with powder coating or sheet finish on the surface. Its role is to protect internal fire extinguishing equipment, prevent the spread of flames in the event of a fire, and form a beautiful exterior of the building.

[0057] The panel coupling part (22) is a structure provided so that the panel body (21) can be easily coupled to the basic frame unit (10). This can be implemented in the form of a fastening hole pre-formed on the edge of the panel, or a clip or bracket attached to the back of the panel. The panel coupling part (22) is designed to be standardized to exactly match the coupling point formed on the basic frame unit (10). The finishing panel unit (20) is assembled in a manner that finally covers the exterior after the fire hydrant fixing unit (100) is installed on the basic frame unit (10).

[0058] The above finishing panel unit (20) functions through a ‘pre-finishing, post-construction’ mechanism. It is brought to the site with all finishing processes, such as painting and sheet attachment, completed at the factory. At the site, the worker brings the above finishing panel unit (20) to the above basic frame unit (10) and then secures it using the above connecting unit (40), such as a screw or clip, through the above panel connecting part (22) to complete the finishing construction. This has the functional feature of fundamentally eliminating complex and contaminating post-processing steps, such as painting, plastering, and wallpapering at the site.

[0059] In one embodiment, it is performed step by step as follows:

[0060] (1) Confirm that the assembly and installation of the above basic frame unit (10) are complete.

[0061] (2) Prepare the above-mentioned finishing panel unit (20) in a state where the final finishing is completed at the factory.

[0062] (3) Align the panel joint portion (22) of the above finishing panel unit (20) to the corresponding position of the above basic frame unit (10).

[0063] (4) The finishing panel unit (20) is fixed to the basic frame unit (10) using the above-mentioned coupling unit (40).

[0064] (5) When installing multiple panels, the joints between the panels are finished with silicone or gaskets to complete the installation.

[0065] The door unit (30) is a component that provides an openable access route so that a user can use the fire hydrant or an administrator can inspect and maintain the internal facilities. The door unit (30) is configured to include a door panel (31), a hinge unit (32) for opening and closing, and a locking unit (33) for keeping the door closed.

[0066] The above door panel (31) serves as the main body of the door, and its material and surface finish are manufactured to be identical or similar to the surrounding finishing panel unit (20) to form an integrated appearance. The above hinge unit (32) connects one side of the above door panel (31) with the side frame of the above basic frame unit (10), thereby enabling the above door panel (31) to open and close around a rotation axis. The above locking unit (33) is composed of a push-type latch or a locking device operated by a key, and serves to prevent the door from opening unintentionally during normal operation. The above door unit (30) is assembled to fit precisely into the opening formed by the above basic frame unit (10).

[0067] The door unit (30) operates as a basic rotational opening and closing mechanism with the hinge unit (32) as the rotation center. Its main function is to be precisely coupled with the basic frame unit (10) and the finishing panel unit (20) without any gaps, so that when closed, it looks like part of the wall. To this end, the door unit (30) is supplied in a pre-assembled form, and installation is completed on-site by simply fixing the hinge unit (32) to the basic frame unit (10).

[0068] In one embodiment, it is performed as follows:

[0069] (1) Complete the installation of the above basic frame unit (10) and the above finishing panel unit (20).

[0070] (2) The pre-assembled door unit (30) is placed in the frame opening.

[0071] (3) One side of the hinge unit (32) is fixed to the door panel (31), and the other side is fixed to the vertical frame (11) of the base frame unit (10) with the coupling unit (40).

[0072] (4) The striker portion of the locking unit (33) is installed at a corresponding position on the basic frame unit (10).

[0073] (5) Open and close the door to check if it operates smoothly and if it is aligned flat without any height difference with the surrounding finish surface when closed, and complete the installation after making adjustments.

[0074] Conventional buried fire hydrant cabinet doors are constructed by welding the frame and fitting the door leaf on-site, resulting in poor precision and frequent sagging or warping of the door over time. The door unit (30) of the present invention is provided in the form of a precisely pre-assembled unit at the factory, thus offering excellent construction precision and durability. Due to precise dimensional management, the possibility of door sagging or gaps occurring after installation is minimized, and consistent opening and closing performance can be maintained for a long period. In addition, installation convenience is maximized. Since on-site welding or complex fitting work is unnecessary and installation is possible with only simple assembly, even non-experts can easily install it, and installation time is reduced.

[0075] The coupling unit (40) is a component that collectively refers to all members that mechanically interconnect and fix each independent unit, such as the aforementioned basic frame unit (10), the finishing panel unit (20), the door unit (30), and the fire hydrant fixing unit (100). Depending on the purpose and location, the coupling unit (40) may include bolts / nuts (41), screws (42), brackets (43), clips (44), etc.

[0076] The bolt / nut (41) is primarily used for joining members of the basic frame unit (10) where strong fastening force is required, or for fixing the fire hydrant fixing unit (100) to the basic frame unit (10). The screw (42) is used to attach the finishing panel unit (20) to the basic frame unit (10) or to fix the basic frame unit (10) itself to a building wall. The bracket (43) is an auxiliary member in the shape of an L or C to connect two members located on different planes or to provide additional support. The clip (44) is a member that allows finishing panels to be quickly attached and detached using elasticity, and can be primarily used to fix panels in areas that are frequently inspected. All these joining units serve to ensure that each unit is assembled correctly in its proper position and performs the required structural performance.

[0077] In one embodiment, it is performed as follows:

[0078] (1) When assembling the vertical frame (11) and horizontal frame (12) of the above basic frame unit (10), bolts / nuts (41) are fastened in designated holes.

[0079] (2) When fixing the assembled basic frame unit (10) to the wall of a building, screws (42) or anchor bolts are used.

[0080] (3) When installing the above fire hydrant fixing unit (100), the bracket (43) and bolt / nut (41) are used together to securely fix it.

[0081] (4) When attaching the above finishing panel unit (20), a screw (42) or a clip (44) is selected and fastened according to the type of finishing.

[0082] Hereinafter, a fire hydrant fixing unit (100) according to a preferred embodiment of the present invention will be described in detail with reference to the attached drawings. The fire hydrant fixing unit (100) is a mechanical device designed to mechanically and precisely fix a fire hydrant embedded inside a building and to facilitate the separation and access of the fire hydrant during maintenance.

[0083] A fire hydrant fixing unit (100) according to one embodiment of the present invention may be configured to include: a unit frame structure (110) forming the framework of the entire structure; a fire hydrant support member (200) installed within the unit frame structure (110) to directly support the fire hydrant and change the position of the fire hydrant through rotational driving force; a disc adjustment member (300) that controls the rotation angle of the fire hydrant support member (200) and fixes it at a specific position; and a spherical fastening member (400) that physically locks or unlocks the rotational disc (210) of the fire hydrant support member (200) as part of the disc adjustment member (300).

[0084] The above-mentioned fire hydrant support member (200) is a primary functional part that directly grips the fire hydrant and changes its position by means of driving force. The above-mentioned fire hydrant support member (200) includes a rotating disk (210), a disk shaft (211), a head support shaft (220), a support member head (230), a fire hydrant sensing member (240), and a motor (280) that generates and transmits driving force, a gear shaft (270), a vertical spur gear (260), and a horizontal spur gear (250).

[0085] The rotating disk (210) is a disc-shaped member, and its role is to receive the rotational force of the motor (280), which will be described later, and to determine the horizontal position of the fire hydrant. The rotating disk (210) is rotatably installed on the upper frame of the unit frame structure (110), and a plurality of adjustment grooves (212) for coupling with the disk adjustment part (300) are formed at regular angular intervals on its circumference.

[0086] The disc shaft (211) and the head support shaft (220) serve as power transmission shafts, and their role is to transmit rotational force to the support head (230) that is in direct contact with the fire hydrant. The disc shaft (211) is positioned vertically, with its upper end penetrating the center of the rotating disc (210) and its lower end fixedly assembled to the center of the horizontal spur gear (250). The head support shaft (220) is fixedly installed to protrude horizontally from the side of the disc shaft (211).

[0087] The support head (230) is a member that directly wraps around and supports the perimeter of the fire hydrant. The support head (230) is connected to and assembled at the end of the head support shaft (220). Normally, it stably fixes the fire hydrant, and when replaced, it performs the role of a guide that pushes the fire hydrant forward through rotational movement.

[0088] The fire hydrant sensing member (240) is a sensor that serves to quantitatively verify the mounting status of the fire hydrant. Multiple sensors (A, B, and C in the drawing) are installed at regular intervals in a vertical direction on the inner surface of the support head (230), that is, the surface in contact with the fire hydrant. Each sensor measures the pressure generated when the fire hydrant is attached, and determines that it is properly attached only when the measured values ​​of all sensors fall within a pre-set standard range (e.g., 30 to 35 N), thereby providing a basis for determining whether the fire hydrant is accurately attached without tilting.

[0089] The motor (280) and gear section (250, 260, 270) are power sources that provide driving force to the rotating disk (210). The motor (280) is fixedly installed on the lower frame of the unit frame structure (110). The rotation axis of the motor (280) is connected to a vertical spur gear (260) placed inside the unit frame structure (110) via a gear shaft (270). The vertical spur gear (260) is installed to mesh with a horizontal spur gear (250) assembled at the bottom of the disk shaft (211).

[0090] The above-mentioned disk adjustment part (300) and spherical fastening part (400) serve as locking devices that control and lock the rotation of the above-mentioned rotating disk (210).

[0091] The adjustment unit support body (310) and the driving unit (311, 312) are the frame and driving unit of the disk adjustment unit (300). The adjustment unit support body (310) is fixedly installed on the side of the unit frame structure (110). Inside the adjustment unit support body (310), a pair of shaft rotation gears (312) are installed to rotate the adjustment unit drive shaft (311), and the adjustment unit drive shaft (311) is installed vertically by engaging between the shaft rotation gears (312).

[0092] The adjustment frame (320, 340) and the joint axis (330) are link structures that convert rotational motion into motion close to a straight line. The first adjustment frame (320) is fixedly assembled to the top of the adjustment drive shaft (311). The second adjustment frame (340) is rotatably connected to the first adjustment frame (320) through the joint axis (330).

[0093] The spherical fastening part (400) is an actuator part that directly locks the rotating disk (210). The spherical fastening part (400) is assembled inside a fastening part installation groove (350) formed at the end of the second adjustment part frame (340). The internal configuration includes a fastening part lifting cylinder (430) that performs a lifting motion, a fastening part magnetic member (440) that attaches the fastening part sphere (450) by magnetic force, and a sphere lifting head (470) and a sphere lifting spring (460) that assist in the separation of the fastening part sphere (450).

[0094] In one embodiment, it is performed as follows:

[0095] When the administrator applies a control signal, the motor (280) is driven to generate rotational force. This rotational force is transmitted in the order of the gear shaft (270), vertical spur gear (260), and horizontal spur gear (250). The disk shaft (211) connected to the horizontal spur gear (250) rotates, and as a result, the rotating disk (210) connected to the disk shaft (211) and the head support shaft (220) rotate in synchronization. The rotation of the head support shaft (220) rotates the support head (230), thereby performing the function of pushing the fire hydrant fixed to the support head (230) forward of the panel (when separated) or returning it to its original position (when fixed).

[0096] In one embodiment, when the fire hydrant is fixed in the correct position, the rotation of the rotating disk (210) must be prevented to fix the position. To this end, the disk adjustment unit (300) operates. First, a power source inside the adjustment unit support body (310) rotates the shaft rotation gear (312) to rotate the adjustment unit drive shaft (311). As a result, a link composed of the first adjustment unit frame (320) and the second adjustment unit frame (340) is deployed, causing the spherical fastening unit (400) to approach the circumference of the rotating disk (210). When the approach is complete, the fastening unit lifting cylinder (430) of the spherical fastening unit (400) lowers, and the fastening unit sphere (450), which is magnetically attached to the bottom, is inserted into the adjustment groove (212) of the rotating disk (210). Thus, the rotating disk (210) becomes locked, making physical rotation impossible.

[0097] In one embodiment, when unlocking, the operation is performed in the reverse order of the locking mechanism. The fastening part lifting cylinder (430) rises to separate the fastening part sphere (450) from the adjustment groove (212). At this time, the sphere lifting springs (460) on both sides push the sphere lifting head (470) to press the side of the fastening part sphere (450), thereby assisting the fastening part sphere (450) to smoothly detach from the adjustment groove (212). Subsequently, the link structure of the disk adjustment part (300) returns to its original position, and the rotating disk (210) becomes freely rotatable.

[0098] In one embodiment, it is performed as follows:

[0099] In the fire hydrant fixing stage,

[0100] (1) The manager brings the fire hydrant close to the support head (230).

[0101] (2) According to the control command, the motor (280) operates to rotate the support head (230) to wrap around the fire hydrant and move it to the correct position.

[0102] (3) The fire hydrant sensing member (240) measures the pressure of the fire hydrant, and if the values ​​of all sensors fall within the standard range, it sends a normal installation signal to the control unit. If the values ​​fall outside the standard range, it sends a warning notification to the manager to induce re-installation.

[0103] (4) When a normal mounting signal is confirmed, the disc adjustment unit (300) operates to insert the connecting part (450) of the spherical connecting part (400) into the adjustment groove (212) of the rotating disc (210) to physically lock the rotation. This completes the fire hydrant fixing procedure.

[0104] In the fire hydrant separation (replacement) stage,

[0105] (1) The administrator enters a fire hydrant disconnection command through the control panel or remote device.

[0106] (2) The spherical fastening part (400) of the above-mentioned disk adjustment part (300) operates first to separate the fastening part spherical part (450) that was inserted into the adjustment groove (212) and unlock it.

[0107] (3) When unlocking is complete, the motor (280) of the fire hydrant support (200) is driven.

[0108] (4) The driving force of the motor (280) rotates the rotating disk (210) and the support head (230) through the gear section.

[0109] (5) The rotational movement of the support head (230) safely pushes the fire hydrant from the interior space of the wall into the open space in front of the panel.

[0110] (6) The manager can easily repair the fire hydrant that protrudes forward or replace it with a new fire hydrant.

[0111] The fire hydrant fixing unit (100) of the present invention provides the following technical effects compared to conventional simple brackets or manual fixing devices.

[0112] Conventional technology involves a high risk of musculoskeletal injury and long working hours because workers must directly handle heavy fire hydrants within a narrow PD space. The present invention reduces the physical burden on workers by more than 90% (where 90% is based on the reduction rate of the force directly applied by the worker to withdraw the fire hydrant) through a mechanism that automatically discharges the fire hydrant to the front of the work space, and significantly lowers the risk of safety accidents.

[0113] Conventional fixing methods rely on the skill level of the operator, and there is a possibility that the fixation may be released due to vibration or external impact. The present invention precisely fixes the rotating disk (210) at a specific angle through a mechanical locking device, a disk adjustment part (300), and a spherical fastening part (400), thereby maintaining a consistent and robust fixed state regardless of changes in the external environment.

[0114] In conventional technology, the mounting status of a fire hydrant can only be checked visually, making it difficult to detect incomplete connections. The present invention provides a basis for quantitatively measuring the pressure during mounting through a fire hydrant sensing member (240), converting it into data, and enabling remote monitoring. This has the effect of increasing the reliability of the fire extinguishing equipment during normal operation.

[0115] A fire hydrant fixing system according to one embodiment of the present invention may include not only hardware components but also a fastening determination module as a software component for precisely controlling their operation.

[0116] The above-mentioned connection determination module is software logic that analyzes pressure measurements received from the fire hydrant sensing member (240) to determine whether the connection state of the fire hydrant satisfies predefined normal conditions. To ensure the safety and reliability of the entire system, the above-mentioned connection determination module controls the system so that subsequent physical locking operations are not performed in an incomplete connection state.

[0117] The above-mentioned fastening determination module is executed by a microcontroller unit or a computing device equivalent thereto and is configured to transmit and receive signals with other hardware units. Specifically, the fastening determination module receives pressure measurement values ​​of each sensor from the fire hydrant sensing member (240) and receives a signal indicating whether the fastening operation is completed from the driving motor (280) of the fire hydrant support member (200). In addition, it is configured to output control signals to the controller of the disk adjustment unit (300), a status display unit for displaying the status, and an alarm unit for alarming, depending on the determination result.

[0118] The control information used by the above-mentioned connection determination module to determine the connection status of the fire hydrant may include a minimum normal pressure reference value for determining whether the fire hydrant is effectively connected, a maximum normal pressure reference value for preventing system damage caused by excessive pressure, and a maximum allowable deviation reference value for determining whether the fire hydrant is tilted. Additionally, the control information may further include a measurement stabilization time to exclude the influence of vibration or electrical noise immediately after physical connection.

[0119] Below, the step-by-step control logic of the above-mentioned binding judgment module is explained in detail.

[0120] First, the connection determination module initiates a procedure to determine the connection state when it receives a 'fixing operation completion signal' from the drive motor (280). When the procedure is initiated, the module waits for a pre-set 'measurement stabilization time' and then collects and confirms the final pressure measurement value from each fire hydrant sensing member (240).

[0121] Next, the bonding judgment module checks whether each collected pressure measurement is within the normal range as a first judgment logic.

[0122] In the first judgment logic above, if the measurement value of even a single sensor is lower than the 'minimum normal pressure reference value,' the module determines this as a 'deficient connection error state' where the fire hydrant is not fully inserted. Conversely, if the measurement value of even a single sensor exceeds the 'maximum normal pressure reference value,' the module determines this as an 'overpressure connection error state' that could strain the system. If any of the above error states are determined, the error handling procedure described below is executed.

[0123] If the above first judgment logic is passed normally, the connection judgment module then determines whether the fire hydrant is tilted by examining the uniformity of the measured pressure values ​​as a second judgment logic.

[0124] In the second judgment logic described above, the module calculates the difference between the largest and smallest values ​​among the pressure measurements from all sensors, i.e., the maximum deviation. If the calculated maximum deviation exceeds a pre-set 'maximum allowable deviation threshold,' the module determines this as a 'tilting error state' where the fire hydrant is attached while tilted to one side, and performs an error handling procedure. This is because pressure non-uniformity between sensors implies an unstable posture of the fire hydrant.

[0125] Only when both the first judgment logic and the second judgment logic are passed without error, the connection judgment module finally confirms the current connection state as a 'normal connection state'.

[0126] Based on the final result of the above judgment procedure, the binding judgment module performs the following subsequent control measures.

[0127] When it is determined that the 'normal locking state' is present, the module transmits a 'lock execution signal' to the controller of the disk control unit (300). Upon receiving the signal, the disk control unit (300) performs a locking operation to physically fix the rotating disk (210) according to the mechanism described above. At the same time, the status display unit can be controlled to output a visual signal, such as illuminating a green indicator light, so that the administrator can recognize that the state is normal.

[0128] On the other hand, if any of the 'insufficient fastening error state', 'overpressure fastening error state', or 'tilting error state' is determined, the fastening determination module does not transmit a 'lock execution signal' to the disk adjustment unit (300). This is to ensure safety by preventing the abnormal fastening state from becoming physically fixed. Instead, the module flashes a red indicator light on the status display unit indicating the cause of the error and generates an alarm sound through the alarm unit to induce the administrator to immediately recognize the problem and take action.

[0129] Hereinafter, a comprehensive embodiment in which the components according to the present invention are organically combined to perform the installation and maintenance of a fire hydrant PD panel is described step by step.

[0130] This embodiment describes the process of initially installing a modular PD fire hydrant panel according to the present invention in a PD opening inside a building.

[0131] First, the worker measures the actual dimensions of the PD opening in the building. Based on the measured dimensions, the components of the basic frame unit (10), which were prefabricated in the factory, are brought to the site. The worker operates the length adjustment unit (13) included in the basic frame unit (10) to precisely adjust the overall width and height of the frame, taking into account the error of the opening at the site. The vertical frame (11) and horizontal frame (12) of the basic frame unit (10), which have been adjusted in size, are firmly assembled together using a connecting unit (40), specifically a bolt / nut (41). The completed basic frame unit (10), in the form of a square frame, is placed inside the PD opening, and after aligning the horizontal and vertical, it is firmly fixed to the building wall using a connecting unit (40) in the form of a screw (42). This is a step of forming a stable standard frame for the entire system.

[0132] When the installation of the above basic frame unit (10) is completed, the fire hydrant fixing unit (100) is then installed. The worker places the fire hydrant fixing unit (100) at a designated location inside the above basic frame unit (10). At this time, the unit frame structure (110) of the fire hydrant fixing unit (100) is mechanically connected to the above basic frame unit (10) through a connecting unit (40) such as a bracket (43) and a bolt / nut (41). Through this connection, structural continuity is ensured so that the weight of the fire hydrant and the dynamic load generated during replacement can be safely transferred to the building structure through the above basic frame unit (10).

[0133] Once the installation of all internal machinery is complete, an external finishing process is performed. A worker attaches a finishing panel unit (20), which has been finished at the factory, to the outside of the base frame unit (10). The panel joint (22) of the finishing panel unit (20) is aligned with the standardized joint point of the base frame unit (10) and is quickly secured through a joining unit (40) in the form of a screw (42) or a clip (44). Subsequently, a door unit (30) for fire hydrant access is installed in the opening formed by the base frame unit (10). The hinge unit (32) of the door unit (30) is fixed to the base frame unit (10), thereby completing the construction of the entire panel system. Since all these processes are carried out using only a dry assembly method that excludes wet processes, rapid and clean site management is possible.

[0134] This embodiment describes the process of separating an old or broken fire hydrant from an installed PD panel and replacing it with a new fire hydrant.

[0135] The manager first opens the door unit (30) to access the interior. When a fire hydrant disconnection command is entered through the control device, the system initiates an automated disconnection procedure. First, the disk adjustment unit (300) operates under the control of the connection judgment module. The spherical fastening unit (400) of the disk adjustment unit (300) releases the physical lock of the rotating disk (210) by raising and separating the fastening unit sphere (450) that was inserted into the adjustment groove (212) of the rotating disk (210).

[0136] Once unlocking is complete, the motor (280) of the fire hydrant support (200) is driven. The driving force of the motor (280) rotates the rotating disk (210) and the support head (230) by a predetermined angle through the gear section. The rotational movement of the support head (230) safely pushes the fire hydrant out of the narrow space inside the wall into the open workspace on the front of the panel.

[0137] The manager separates the old fire hydrant, which has been discharged forward and made easily accessible, from the support head (230) and places a new fire hydrant in its place. Then, when the manager inputs a fire hydrant fixing command, the motor (280) of the fire hydrant support (200) is driven in the reverse direction to return the support head (230) to its original position and embrace the new fire hydrant.

[0138] When the fire hydrant returns to its original position, the connection determination module is automatically activated. The fire hydrant sensing member (240) measures the contact pressure with the new fire hydrant and transmits it to the connection determination module. The module analyzes the range and uniformity of the pressure according to the aforementioned control logic to determine whether the connection state is 'normal' or 'error'.

[0139] If it is determined to be an 'error', the system generates an alarm, requests the administrator to re-attach it, and does not perform the locking operation. When the administrator correctly re-attaches the fire hydrant and it is determined to be in a 'normal' state, the attachment determination module finally sends a 'lock execution signal' to the disk adjustment unit (300). Finally, the disk adjustment unit (300) operates to physically lock the rotating disk (210) again, thereby safely and accurately completing all replacement and maintenance work. Afterward, the administrator closes the door unit (30) to finish the work.

[0140] Although preferred embodiments of the present invention have been illustrated and described above, the present invention is not limited to the specific embodiments described above. Various modifications are possible by those skilled in the art without departing from the essence of the invention as claimed in the claims, and such modifications should not be understood individually from the technical spirit or perspective of the present invention.
