Description

Technical Field

[0001] This invention relates to the technical field of port fire alarms, specifically to a networked remote monitoring port fire alarm device and its monitoring system. Background Technology

[0002] Currently, mobile lifting machinery in ports generally uses automatic fire extinguishing devices. Depending on the extinguishing agent used, these devices are generally divided into ultra-fine dry powder automatic fire extinguishing devices and new water-based engine compartment automatic fire extinguishing equipment. These devices integrate detection, alarm, drive, and spraying, providing rapid response and short fire control time. They can achieve 24-hour uninterrupted monitoring and implement automatic fire extinguishing functions. However, due to the large temperature fluctuations during the operation of mobile machinery in ports, the automatic fire extinguishing devices are prone to frequent false triggering, which may lead to their disassembly and affect the safety of the mobile machinery during use.

[0003] To overcome the above-mentioned defects, existing technology 1 (Chinese patent with announcement number CN222167695U, announcement date 2024-12-13) provides a fire alarm device, including a fire alarm body and a mounting plate. A fixing groove is provided on the top outer side of the fire alarm body, and a fixing block is provided at the bottom center of the mounting plate. The fixing block is connected to the inside of the fixing groove by a thread. An extension plate is provided on the bottom surface of the fire alarm body, and a telescopic rod is provided on the top of the extension plate. A fixing plate is provided on the top of the telescopic rod, and the inner surface of the fixing plate contacts the outer surface of the fire alarm body. Based on the existing fire alarm device, a fixing groove is provided on the top of the fire alarm, and the fixing groove is connected to the fixing plate by a thread. The fixing plate is located at the mounting plate, and the mounting plate is fixedly connected to the ceiling by fixing bolts. When the fire alarm body needs to be removed for maintenance or replacement, it can be removed simply by rotating the fire alarm body. Patent No. 2 (Chinese Patent No. CN218332815U, Publication Date: 2023-01-17) discloses a fire alarm device, relating to the field of fire alarm technology. It solves the technical problem that current methods require two people to simultaneously press the button while another person disassembles the alarm body, making single-person disassembly time-consuming, labor-intensive, and hindering the disassembly and assembly process. The new device includes a fire alarm body with a mounting plate on its top. Fixing blocks are fixedly mounted on both sides of the bottom of the mounting plate. Each fixing block has a locking plate inside, and the bottom ends of both locking plates are fixedly connected to the two sides of the top of the fire alarm body. Each fixing block has a hollow groove inside, and each hollow groove contains an installation component. Each installation component includes a limit rod, a limit plate, a retraction spring, and a tilting slider. This design facilitates single-person disassembly and installation of the fire alarm body, saving time and labor, improving disassembly and assembly progress, and making it more convenient to use and operate.

[0004] The aforementioned mechanisms facilitate the disassembly and installation of fire alarms by utilizing the interplay of disassembly and assembly components. However, in actual use, after installation using bolts or mounting components, subsequent disassembly of the fire alarm requires a certain amount of time. When a fire alarm is damaged and needs repair, spending too much time disassembling it will reduce its overall usability during use. Summary of the Invention

[0005] The purpose of this invention is to provide a networked remote monitoring port fire alarm device and its monitoring system, in order to solve the problem mentioned in the background art that when a fire alarm is damaged and needs repair, excessive time is spent disassembling the fire alarm, which leads to a decrease in overall applicability.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a networked remote monitoring port fire alarm device and its monitoring system, comprising a fixed base plate, an mounting base installed on the right side of the top of the fixed base plate, and a fire alarm body installed on the top of the mounting base, the top of the fire alarm body having a fixing hole; a servo motor installed on the left side of the bottom of the fixed base plate, and a mounting mechanism for fixing the servo motor having an output end; the mounting mechanism includes a fixing rod, and the fixing rod is located at the front and rear ends of the bottom of the fixed base plate; a suction cup is provided at the bottom of the fixing rod, and a push rod is installed inside the fixing rod via a piston; a sealing plate is installed at the lower end of the push rod via a connecting spring; a fixing frame is provided on the outside of the fire alarm body, and a cleaning mechanism for wiping the surface of the fire alarm body is provided on the inside of the fixing frame.

[0007] Furthermore, a cam is provided on the left side of the top of the fixed base plate, and the output end of the servo motor is connected to the cam. A mounting bracket is provided at the middle position of the top of the fixed base plate, and a pressing block is connected to the left side of the mounting bracket by a spring, and a pushing block is provided on the right side of the pressing block.

[0008] Furthermore, the cross-section of the propulsion block is an inverted trapezoid, and the top of the propulsion block is at the same horizontal line as the top of the propulsion rod.

[0009] Furthermore, the extrusion block is slidably connected to the fixed base plate, and the extrusion block is located on the right side of the cam.

[0010] Furthermore, the cleaning mechanism includes a cleaning brush, which is disposed on the inner side of the fixed frame. The inner side of the cleaning brush is in contact with the outer side of the fire alarm body. The output end of the servo motor is equipped with a drive gear through a belt pulley transmission mechanism, and a driven gear meshes with the right side of the drive gear. The top end of the driven gear is connected to the bottom end of the fixed frame, and a torsion spring is disposed at the lower end of the driven gear.

[0011] Furthermore, the driving gear is a half gear, and the driving gear is rotatably connected to the bottom end of the fixed base plate.

[0012] Furthermore, the fire alarm body is internally equipped with a suppression mechanism to extend the alarm time. The suppression mechanism includes a shape memory metal sheet, which is disposed on the left and right sides of the top of the mounting base. A movable plate is mounted on the top of the shape memory metal sheet via a fusing block, and an elastic airbag is mounted on the top of the movable plate. Fixed plates are mounted on both sides of the top of the elastic airbag via return springs, and an abutment pin is mounted at the middle position of the bottom end of the fixed plate.

[0013] Furthermore, the abutment pin is positioned above the elastic airbag, and the elastic airbag is positioned below the fixed plate. The fixed plate and the movable plate are connected by a return spring to form an elastic structure.

[0014] Furthermore, guide rods are provided on both the left and right sides of the top of the mounting base, and movable blocks are installed on the outer side of the guide rods by springs. Conductive plates are installed on the bottom of the movable blocks and on both the left and right sides of the top of the mounting base.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The fire monitoring system consists of an ultraviolet flame detector, a smoke detector, and a buzzer. The ultraviolet flame detector detects fires by detecting the ultraviolet rays produced by the combustion of materials, and reacts quickly to fires with strong flame radiation or no smoldering stage. The smoke detector automatically detects the smoke concentration in the surrounding environment every 1.6 seconds. If the smoke concentration is close to the alarm value of 1.06±0.26%FT, the smoke detector starts intelligent calculation. If the calculation result reaches or exceeds the alarm value, the sensor starts an audible and visual alarm and triggers the audible and visual alarm in the driver's cab to be activated simultaneously, completing the fire alarm process.

[0017] Furthermore, after the cam rotates to another angle, the pressing block automatically resets due to the spring force, and the push rod also resets synchronously due to the connecting spring force. The piston reset causes the air inside the suction cup to be extracted and enter the interior of the fixed rod. When the push rod resets, the increased air pressure due to the increased internal air leads to the air pressure pushing the sealing plate upward. The air is discharged from the gap between the push rod and the fixed base plate, allowing the suction cup to be stably adsorbed at the required installation position. At the same time, the repeated rotation of the servo motor output end allows the air inside the suction cup to be continuously extracted, thus maintaining a stable vacuum adsorption state inside the suction cup, making the use of the suction cup more stable.

[0018] Furthermore, the shape of the push block is an inverted trapezoid, which causes the push block to compress the push rod to a certain extent when it is pushed, thereby pushing the push rod downward. After the push block resets, the push rod resets simultaneously, realizing the repeated extraction of gas inside the suction cup.

[0019] 2. The drive gear meshes with the driven gear during rotation, allowing the driven gear to synchronously drive the fixed frame to reciprocate. When the piston rotates, it drives the cleaning brush to rotate, thus allowing the cleaning brush to wipe the outside of the fire alarm body. This keeps the fire alarm body clean during use and reduces the possibility of insufficient brightness during audible and visual alarms due to dust accumulation.

[0020] Furthermore, the shape memory metal sheet and the movable plate are connected by a fusible block. The fusible block melts due to the high temperature of the fire, causing the movable plates to be reset by a return spring. The elastic airbag is synchronously driven to reset and is then punctured by the abutment pin. The inert gas inside the elastic airbag is released and extinguishes the fire inside the fire alarm body, extending the service life of the fire alarm body as much as possible, thereby achieving a better fire alarm effect.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1: As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 10 The technical solution shown addresses the problem of reduced overall applicability caused by excessive time spent disassembling fire alarms during repairs: This networked remote monitoring port fire alarm device and its monitoring system discloses an installation mechanism, including a fixed base plate 1. A mounting base 2 is installed on the right side of the top of the fixed base plate 1, and a fire alarm body 3 is mounted on the top of the mounting base 2. A fixing hole 4 is provided on the top of the fire alarm body 3. A servo motor 5 is installed on the left side of the bottom of the fixed base plate 1, and a mounting mechanism for fixing is provided at the output end of the servo motor 5. The mounting mechanism includes a fixing rod 10, which is positioned at the front and rear of the bottom of the fixed base plate 1. At both ends, a suction cup 11 is provided at the bottom end of the fixing rod 10, and a push rod 12 is installed inside the fixing rod 10 through a piston. A sealing plate 13 is installed at the lower end of the push rod 12 through a connecting spring 14. A cam 6 is provided on the left side of the top of the fixing base plate 1, and the output end of the servo motor 5 is connected to the cam 6. A mounting bracket 7 is provided at the middle position of the top of the fixing base plate 1, and a pressing block 8 is connected to the left side of the mounting bracket 7 through a spring. A push block 9 is provided on the right side of the pressing block 8. The cross-section of the push block 9 is an inverted trapezoid, and the top of the push block 9 is at the same horizontal line as the top of the push rod 12. The pressing block 8 is slidably connected to the fixing base plate 1, and the pressing block 8 is located on the right side of the cam 6.

[0034] In this example, the fire monitoring system consists of an ultraviolet flame detector, a smoke detector, and a buzzer. The ultraviolet flame detector detects the fire spectrum (180nm-290nm) by detecting the ultraviolet light produced by burning materials, and reacts quickly to fires with strong flame radiation or no smoldering stage. The smoke detector automatically detects the smoke concentration in the surrounding environment every 1.6 seconds. If the smoke concentration approaches the alarm value of 1.06±0.26%FT, the smoke detector begins intelligent calculation. If the calculation result reaches or exceeds the alarm value, the sensor starts an audible and visual alarm and triggers the audible and visual alarm in the driver's cab to activate simultaneously, completing the fire alarm process. The output of the servo motor 5 rotates and drives the cam 6 to rotate, so that the cam 6 continuously squeezes the compression block 8, which pushes the compression block 8 to the right. In turn, the compression block 8 pushes the pusher block 9 to the right. The lower right end of the pusher block 9 is in contact with the top end of the pusher rod 12, pushing the pusher rod 12 downward. The bottom end of the pusher rod 12 pushes the piston downward. As the cam 6 rotates to another angle, the compression block 8 automatically resets due to the spring force, and the push rod 12 also resets synchronously due to the spring force of the connecting spring 14. The piston reset causes the air inside the suction cup 11 to be extracted and enter the interior of the fixing rod 10. When the push rod 12 resets, the increased air pressure due to the increased internal air pressure causes the sealing plate 13 to be pushed upward. The air is discharged from the gap between the push rod 12 and the fixing base plate 1, so that the suction cup 11 can be stably adsorbed at the required installation position. At the same time, the repeated rotation of the output end of the servo motor 5 can continuously extract the air inside the suction cup 11, thereby maintaining a stable vacuum adsorption state inside the suction cup 11, making the use of the suction cup 11 more stable. The push block 9 is inverted trapezoidal in shape, so when the push block 9 is pushed, it will squeeze the push rod 12 to a certain extent, thereby pushing the push rod 12 downward. After the push block 9 resets, the push rod 12 resets synchronously, realizing the repeated extraction of gas inside the suction cup 11.

[0035] Example 2: Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 9The technical solution shown addresses the problem that dust accumulates on the surface of the fire alarm body 3 during prolonged use, leading to insufficient light flickering during audible and visual alarms. This networked remote monitoring port fire alarm device and its monitoring system discloses a cleaning mechanism. A mounting bracket 15 is installed on the outer side of the fire alarm body 3, and a cleaning mechanism for wiping the surface of the fire alarm body 3 is installed on the inner side of the mounting bracket 15. The cleaning mechanism includes a cleaning brush 19, which is located on the inner side of the mounting bracket 15 and fits against the outer side of the fire alarm body 3. A drive gear 16 is installed at the output end of the servo motor 5 via a belt pulley transmission mechanism. A driven gear 17 meshes with the right side of the drive gear 16. The top of the driven gear 17 is connected to the bottom end of the mounting bracket 15, and a torsion spring 18 is installed at the lower end of the driven gear 17. The drive gear 16 is a half-gear and is rotatably connected to the bottom end of the fixed base plate 1.

[0036] In this example, the output of the servo motor 5 drives the drive gear 16 to rotate via a belt drive mechanism. When the drive gear 16 rotates, it meshes with the driven gear 17, which in turn drives the fixed frame 15 to rotate back and forth. When the fixed frame 15 rotates, it drives the cleaning brush 19 to rotate, which in turn wipes the outside of the fire alarm body 3. This keeps the fire alarm body 3 clean during use and reduces the possibility of insufficient brightness during audible and visual alarms due to dust accumulation. At the same time, the drive gear 16 is a half gear, so it cannot mesh with the driven gear 17 after a certain angle. This allows the driven gear 17 to reset its angle via the torsion spring 18, and the fixed frame 15 is simultaneously driven to reset. This allows the fixed frame 15 and the cleaning brush 19 on its inner side to reciprocate and clean the outside and top of the fire alarm body 3.

[0037] Example 3: Figure 1 , Figure 2 , Figure 7 and Figure 8The technical solution shown addresses the problem that, during a fire, the fire alarm body 3, being near a fire, is susceptible to fire damage, leading to a shortened lifespan. This networked remote monitoring port fire alarm device and its monitoring system disclose a suppression mechanism. The fire alarm body 3 is internally equipped with this mechanism to extend the alarm time. The suppression mechanism includes shape memory metal sheets 20, which are located on the left and right sides of the top of the mounting base 2. A movable plate 22 is mounted on the top of the shape memory metal sheets 20 via a fusible block 21. An elastic airbag 23 is installed at the top of the device. A fixed plate 24 is installed on both sides of the top of the elastic airbag 23 via a return spring 26. An abutment pin 25 is installed at the middle position of the bottom of the fixed plate 24. The abutment pin 25 is positioned above the elastic airbag 23, and the elastic airbag 23 is positioned below the fixed plate 24. The fixed plate 24 and the movable plate 22 form an elastic structure through the return spring 26. Guide rods 29 are provided on both the left and right sides of the top of the mounting base 2. A movable block 27 is installed on the outer side of the guide rod 29 via a spring. Conductive sheets 28 are installed on the bottom of the movable block 27 and on both the left and right sides of the top of the mounting base 2.

[0038] In this example, when the fire is severe and spreads to the vicinity of the fire alarm body 3, the shape memory metal sheet 20 and the movable plate 22 are connected by a fusible block 21. The fusible block 21 melts due to the high temperature of the fire, causing the movable plate 22 to reset via the return spring 26. The elastic airbag 23 is synchronously driven to reset and is then punctured by the abutment pin 25. The inert gas inside the elastic airbag 23 is released and extinguishes the fire inside the fire alarm body 3, extending the service life of the fire alarm body 3 as much as possible, thereby achieving a better fire alarm effect. At the same time, the shape memory metal sheet 20 changes shape from an "L" shape after being heated and resets to a straight shape. After resetting, the shape memory metal sheet 20 presses the movable block 27, causing the conductive sheet 28 at the bottom of the movable block 27 to contact and adhere to the conductive sheet 28 at the top of the mounting base 2, thereby achieving secondary alarm processing and increasing applicability during use.
