[0001] This utility model relates to the field of ship cargo hold water ingress alarm technology, and in particular to a ship cargo hold water ingress detection and alarm system that can be remotely monitored. Background Technology

[0002] A ship cargo hold flood alarm sensor is a device specifically designed to detect water ingress into a ship's cargo hold. Its technical background mainly involves the following aspects: Sensor technology: Ship cargo hold flood alarm sensors typically use level sensors, leakage sensors, etc. These sensors operate based on principles of capacitance, resistance, magnetism, and sound waves, monitoring changes in the water level within the cargo hold. Advances in sensor technology have enabled flood alarm sensors to detect water level changes in the cargo hold more accurately and reliably. Wireless communication technology: Ship cargo hold flood alarm sensors generally require remote monitoring; therefore, wireless communication technology is needed to transmit the data collected by the sensor to a monitoring center on shore. Advances in wireless communication technology have made transmission faster and more reliable, while also reducing maintenance costs. Digital signal processing technology: Due to… Ship cargo hold flood alarm sensors need to monitor the water levels of multiple cargo holds in real time. Therefore, digital signal processing technology is required to process the data collected by the sensors in real time to issue alarm information promptly. Data analysis technology is also crucial: the data collected by the ship cargo hold flood alarm sensors needs to be processed and analyzed to determine the severity of the flooding. With the development of data analysis technology, ship cargo hold flood alarm sensors can achieve more accurate data analysis, thereby improving ship safety. In summary, the technical background of ship cargo hold flood alarm sensors mainly includes sensor technology, wireless communication technology, digital signal processing technology, and data analysis technology. The development of these technologies makes ship cargo hold flood alarm sensors more accurate and reliable in detecting changes in water level in cargo holds, providing a guarantee for shipping safety.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0027] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0029] Combination Figure 1-4 This embodiment discloses a remotely monitorable ship cargo hold water ingress detection and alarm system for on-site and remote dual-position monitoring of accidental water ingress into ship cargo holds.

[0030] The hardware includes a main body, which includes a detachable back panel 1 and a panel 2. The back panel 1 is connected to the cargo hold wall by bolts. The back panel 1 can be installed on the side wall of the same cargo hold in different locations according to actual needs. The back panel 1 mainly serves as a mounting base. The panel 2 is connected to the back panel 1 by a snap-fit ​​structure, which can be easily disassembled and installed, and is convenient for maintenance.

[0031] Combination Figure 2 and Figure 6As shown, a circuit board 6 is installed inside the panel 2. The circuit board 6 includes a central processing module, a storage module, a power supply module, a sensor module, and an alarm module for collaborative operation. It is also connected to an external remote data center module through a transmission module. The connections between the modules are all existing technologies. Their specific structures and working principles will not be described in detail here. Those skilled in the art can select and implement them from existing technologies according to actual operating conditions.

[0032] In this embodiment, the sensor module includes a humidity sensor 7. The detection end 71 of the humidity sensor 7 is connected to a moisture-wicking element 8. The moisture-wicking element 8 is made of absorbent cotton thread, extends to the outside of the panel 2, and is detachably installed on the cargo hold wall. The moisture-wicking element 8 can conduct water entering from the cargo hold wall to the detection end 71 of the humidity sensor 7. In actual use, if water leaks from the cargo hold side wall, the seepage water on the wall will be "captured" by the moisture-wicking element 8 in a specific area, and the humidity brought by the water will be conducted to the detection end 71, enabling efficient humidity monitoring.

[0033] Furthermore, the detection end 71 of the humidity sensor 7 is provided with a double-sided humidity-sensitive element. In this embodiment, the humidity-sensitive element is a humidity-sensitive capacitor made of polymer thin film capacitor, and is configured with a corresponding detection circuit. Combined with... Figure 3 As shown, the moisture-wicking component 8 has a "U"-shaped wrapping end 81 on the side near the humidity sensor 7. The inner side of the wrapping end 81 is attached to the detection end 71 through a water-permeable adhesive component 82.

[0034] Specifically, in combination Figure 4 The adhesive layer 82 has an adhesive layer structure with a plurality of water-permeable holes 83 evenly distributed thereon. The function of the air-permeable holes is to increase the conduction efficiency of water at the detection end 71. The center of each water-permeable hole 83 is a circular through hole, and a plurality of strip-shaped through holes are arranged symmetrically around the circular through hole. The inner ends of the strip-shaped through holes are connected to the circular through hole. This structure allows for sufficient water conduction in the center of the water-permeable hole 83, while the periphery provides auxiliary conduction, thereby increasing the conduction contact area and ensuring the detection efficiency and quality of the detection end 71.

[0035] Other, such as Figure 1 As shown, the alarm module includes an alarm light 4 and a speaker 5 installed on the panel 2. The alarm light 4 provides a light alarm signal, and the speaker 5 provides a sound alarm signal, which can provide a conspicuous alarm message on site and help on-site personnel to find the location of water ingress in the cargo hold in a timely manner.

[0036] Furthermore, the front of the panel 2 is also provided with a display screen 3 for displaying the operating parameters of the device.

[0037] In the specific implementation process, if water seepage occurs in the detection area covered by the exposed area of ​​the moisture-wicking component 8, the water will quickly reach the detection end 71 of the humidity sensor 7 along the moisture-wicking component 8. After the humidity sensor 7 detects the humidity change information, it transmits the signal to the central processing module. The central processing module calculates the detection structure by comparing the sample value and the threshold, and sends it to the alarm module and the remote data center module at the same time. The remote data center module further transmits the detection signal to other output devices to achieve the effect of remote monitoring.

[0038] In another embodiment, such as Figure 5 As shown, the moisture-wicking component 8 has an extension section 84 on the side away from the humidity sensor 7. The extension section 84 is located on the outside of the panel 2. The extension section 84 is provided with several extension claws 85. The function of the extension section 84 and the extension claws 85 is to increase the coverage area of ​​the moisture-wicking component 8 and increase the detection coverage area.

[0039] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
