Description

Technical Field

[0001] This utility model relates to the field of ship box-type power supply technology, and in particular to an emergency abandonment positioning structure for ship box-type power supplies. Background Technology

[0002] With the acceleration of the global energy transition, the demand for shipboard power supplies (especially lithium battery storage boxes) as mobile power supply devices is growing rapidly in maritime transport. These devices, due to their integrated high-energy-density lithium battery packs, are classified as Class 9 dangerous goods under the International Maritime Dangerous Goods Code (IMDG Code), with the UN number UN3536. Their maritime transport must strictly adhere to the UN38.3 testing standard and relevant regulations such as JT / T 1543—2025 "Safety Technical Requirements for Lithium Batteries Transported by Ships." Shipboard power supplies typically weigh over 30 tons each. During maritime transport and loading / unloading, they are susceptible to factors such as ship tilting and vibration, changes in weather and sea conditions, and failure of mooring and lashing. Furthermore, the internal lithium batteries pose a risk of thermal runaway. In the event of a fire, they are characterized by high combustion temperatures, difficulty in extinguishing, and a high risk of reignition. In extreme cases, emergency abandonment at sea is necessary to ensure the safety of the ship and personnel, which is a core manifestation of the "human life first" principle in maritime emergency response.

[0003] Currently, the safety monitoring of shipboard containerized power supplies mainly relies on shipboard centralized monitoring systems and conventional dangerous goods monitoring equipment. Existing technologies mostly focus on status monitoring during transportation (such as temperature, voltage, and smoke detection), but there are significant shortcomings in positioning and tracking technology for the extreme scenario of "emergency abandonment at sea." Furthermore, there is a disconnect between relevant regulations and technological development. International maritime rules such as the SOLAS Convention and the MARPOL Convention only explicitly require timely reporting of lost containers, without mandating that containerized power supplies have independent and continuous positioning and tracking capabilities after being abandoned at sea. Although domestic guidelines have gradually improved the safety requirements for the entire chain of containerized power supply transportation at sea, they have not proposed specific technical solutions for the positioning process after abandonment at sea, resulting in existing positioning technologies being unable to adapt to the special working conditions required for abandoning containerized power supplies at sea.

[0004] Among existing positioning technologies, some shipborne dangerous goods monitoring devices only have the function of monitoring the status during transportation and lack the ability to locate after falling into the water; a small number of positioning devices are mostly general-purpose designs, using a single immersion trigger mode, without taking into account the special scenario of emergency abandonment of the ship at sea, and are prone to falsely triggering positioning reports due to non-abandonment scenarios such as being splashed by sea waves or accumulating water in the cabin during navigation.

[0005] Therefore, a shipboard box-type power supply emergency abandonment positioning structure is provided to address the above-mentioned problems. Utility Model Content

[0006] This invention provides a shipboard box-type power supply emergency sea-abandonment positioning structure to solve the technical problem of how to avoid false triggering of positioning reports in non-emergency sea-abandonment states.

[0007] This utility model solves the above-mentioned technical problems through the following technical solutions: This utility model provides an emergency positioning structure for a ship's box-type power supply, including a positioning device. A mounting groove is provided at the center of the top of the ship's box-type power supply, and a base plate is fixedly installed on the bottom wall of the groove. The positioning device is fixed to the base plate via a mounting assembly. The positioning device contains a multi-parameter sensing module, a main control module, a positioning module, and an information reporting module, all of which are electrically connected to the main control module. The multi-parameter sensing module is equipped with a water immersion electrode sensor and a triaxial acceleration sensor. The water immersion electrode sensor is used to detect whether the ship's box-type power supply has fallen into the water. A three-axis accelerometer is used to monitor whether the ship's box-type power supply has reached the acceleration required for being jettisoned at sea. When the ship's box-type power supply is detected to have fallen into the water and reached the acceleration required for being jettisoned at sea, the main control module performs real-time positioning through the positioning module and simultaneously reports the information in real-time through the information reporting module. The bottom of the positioning device is provided with a mounting cavity with a bottom opening, and a battery is fitted inside the mounting cavity. A sealing ring is provided at the bottom of the positioning device, and the sealing ring is located on the outside of the bottom of the mounting cavity. The base plate is provided with multiple positioning parts and multiple clamping parts. The positioning parts are connected to the bottom of the battery, and the clamping parts abut against the bottom of the battery.

[0008] Preferably, the multi-parameter sensing module is further provided with a water pressure sensor and a temperature sensor; the water pressure sensor and the immersion electrode sensor are disposed on the outer wall of the positioning device.

[0009] Preferably, there are multiple mounting components, and the multiple mounting components are evenly distributed on both sides of the positioning device.

[0010] Preferably, the mounting assembly includes a fixing seat fixed to the base plate and a sleeve fixed to the bottom side of the positioning device. A stud is fixed on the fixing seat, the sleeve is sleeved on the stud, and a nut is threaded onto the stud.

[0011] Preferably, the positioning part includes a positioning post fixed to the top surface of the base plate and a positioning sleeve fixed to the bottom of the battery, wherein the positioning post and the positioning sleeve are inserted into each other.

[0012] Preferably, the clamping part includes a first spring, which is sleeved on the positioning post.

[0013] Preferably, the base plate is provided with an annular insert, and the insert is provided with an annular groove along its length direction, and the sealing ring is embedded in the annular groove.

[0014] Preferably, a finger groove is formed on one side wall of the mounting cavity.

[0015] Preferably, a lever is fixed to one side of the bottom of the battery, and the lever extends into the finger groove.

[0016] Preferably, an inner sealing component is provided inside the sealing ring. The inner sealing component includes a corrugated folded soft sleeve. The top end of the corrugated folded soft sleeve is fixed to the bottom surface of the positioning device. A pressure plate is fixed to the bottom end of the corrugated folded soft sleeve, and a sealing gasket is provided on the bottom surface of the pressure plate. The pressure plate is elastically connected to the bottom surface of the positioning device through a second spring.

[0017] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.

[0018] The positive and progressive effects of this utility model are as follows: The aforementioned shipboard box-type power supply emergency abandonment positioning structure adopts a multi-condition joint triggering logic of "throwing acceleration + immersion state", which overcomes the problem that the existing single immersion triggering mode is prone to false triggering due to sea waves splashing and water accumulation in the cabin.

[0019] The mounting cavity for battery installation is located at the bottom of the positioning device. Together with a sealing ring and a base plate, the sealing ring presses against the base plate during installation, creating a seal and eliminating the need for an additional sealing cover. When the positioning device is disassembled for maintenance or battery replacement, the mounting cavity remains uncovered after removing the mounting components, eliminating the need for cover removal. The positioning and pressing components provide a limiting position for the battery after installation, ensuring its stability within the mounting cavity.

[0020] By using a sealing ring in conjunction with an inner sealing component, a double sealing structure is provided for the installation cavity after the positioning device is installed, which improves the sealing effect. At the same time, the inner sealing component provides pressure to the sealing gasket through the compression force of the second spring, ensuring the sealing effect. Attached Figure Description

Detailed Implementation

[0023] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0024] like Figures 1-8 As shown, the shipboard box-type power supply emergency abandonment positioning structure includes a positioning device 3; the shipboard box-type power supply 1 has an installation groove 4 at the top center, and a base plate 5 is fixedly installed on the bottom wall of the installation groove 4.

[0025] The positioning device 3 is fixed to the base plate 5 by an installation component.

[0026] The positioning device 3 is equipped with a multi-parameter sensing module 14, a main control module 15, a positioning module 16, and an information reporting module 17, and the multi-parameter sensing module 14, the positioning module 16, and the information reporting module 17 are all electrically connected to the main control module 15.

[0027] The multi-parameter sensing module 14 is equipped with a water immersion electrode sensor 1401 and a triaxial acceleration sensor 1403; the water immersion electrode sensor 1401 is used to detect whether the ship's box-type power supply 1 has fallen into the water; the triaxial acceleration sensor 1403 is used to monitor whether the ship's box-type power supply 1 has reached the acceleration required for being jettisoned at sea; by monitoring the change in acceleration, it is determined whether the ship's box-type power supply 1 has been jettisoned at sea.

[0028] When the ship's box-type power supply 1 is detected to have fallen into the water and reached the acceleration required to be thrown into the sea, the main control module 15 performs real-time positioning through the positioning module 16 and simultaneously reports the information in real-time through the information reporting module 17.

[0029] The positioning device 3 has a mounting cavity 302 with a bottom opening at its bottom, and a battery 9 is embedded in the mounting cavity 302. The battery 9 is used to power the positioning device 3. The bottom of the positioning device 3 is provided with a sealing ring 10, and the sealing ring 10 is located on the outside of the bottom of the mounting cavity 302.

[0030] The base plate 5 is provided with multiple positioning parts and multiple pressing parts. The positioning parts are connected to the bottom of the battery 9, and the pressing parts abut against the bottom of the battery 9.

[0031] The aforementioned positioning structure uses a dual-parameter method to determine whether the ship's box-type power supply 1 has been abandoned at sea. The immersion electrode sensor 1401 detects whether it is immersed in water to determine whether it has fallen into the water. The triaxial acceleration sensor 1403 monitors acceleration changes to identify whether the ship's box-type power supply 1 has been abandoned. When the conditions of "acceleration threshold met (acceleration ≥ 5 m / s², recognizing the abandonment action) + immersion signal valid (confirming falling into the water)" are met, it is determined that the ship's box-type power supply 1 has been abandoned at sea in an emergency, and then enters the working mode to report positioning information in real time. When it is determined that it has not been abandoned at sea, it is in standby mode, does not locate, and does not report information.

[0032] By using the above dual-parameter design to determine whether to abandon the sea, false triggering is avoided. Unlike the positioning structure in the existing technology that uses a single immersion trigger mode, when seawater enters the immersion electrode sensor 1401 in non-abandonment scenarios such as being splashed by waves or accumulating water in the cabin during navigation, positioning will not be triggered.

[0033] In the aforementioned positioning structure, the battery 9 is installed and sealed. When the positioning device 3 is fixedly installed, the sealing ring 10 at the bottom presses against the base plate 5 to form a seal, so that the mounting cavity 302 does not need to be sealed with an additional sealing cover. When the positioning device 3 is disassembled and repaired, after the mounting components on the positioning device 3 are disassembled and repaired, there is no cover at the mounting cavity 302, so there is no need to remove or install the cover.

[0034] Simultaneously, a positioning part and a pressing part are provided. After the positioning device 3 is installed, the positioning part provides positioning for the battery 9, while the pressing part presses the battery 9 to provide reliable limit for the battery 9 and avoids the problem of poor contact at the power connection position of the battery 9.

[0035] like Figure 2 and Figure 7As shown, the multi-parameter sensing module 14 is also equipped with a water pressure sensor 1402 and a temperature sensor 1404; the water pressure sensor 1402 and the immersion electrode sensor 1401 are disposed on the outer wall of the positioning device 3.

[0036] The water pressure sensor 1402 is used to detect the depth after the object falls into the water; the temperature sensor 1404 is used to detect the ambient temperature of the ship's box-type power supply 1.

[0037] The main control module 15 uses an STM32L476 microcontroller as its core and has a built-in preset multi-condition triggering algorithm. It only starts the positioning working mode when it detects "acceleration ≥ 5m / s² (throwing action) + water immersion signal valid" to avoid false triggering. At the same time, it integrates a data storage unit to record nearly 72 hours of status data for easy subsequent traceability.

[0038] The positioning module 16 adopts a multi-mode positioning mode of "BeiDou / GPS dual-mode positioning + AIS automatic identification system + maritime satellite backup". BeiDou / GPS is used to accurately obtain position coordinates, AIS system is used to broadcast positioning information to surrounding ships and shore-based equipment, and maritime satellite is used to achieve stable transmission of positioning signals in the open sea and areas with weak signals, so as to ensure continuous positioning after falling into the water, whether it is near the shore or in the open sea, floating or semi-submerged.

[0039] Meanwhile, the positioning module 16 has a built-in identity coding unit that pre-stores the core information of the ship's box-type power supply 1, including the box number, UN3536 dangerous goods label, battery capacity, manufacturer, ship name, loading location, etc. The positioning signal and identity information are transmitted synchronously to achieve integrated reporting of "location + identity".

[0040] The information reporting module 17 adopts an NB-IoT communication module. In accordance with the requirements of the SOLAS Convention, IMDG Rules and MARPOL Convention, it presets a standardized reporting format, packages the location information and container identification information into standardized messages, and reports once every 5 minutes (after falling into the water), directly connecting to the maritime supervision platform and shore-based monitoring center.

[0041] In summary, the positioning device 3 achieves integrated reporting of the "location + identity" of the ship's box-type power supply 1, and the reporting format strictly follows the requirements of the SOLAS Convention, IMDG Code and MARPOL Convention. At the same time, it automatically generates standardized reporting logs, which solves the problems of non-standard information reporting and missing certificates of existing positioning devices, and ensures that the ship owner and maritime authorities complete compliant reporting and subsequent investigations.

[0042] like Figure 2 , Figure 3 , Figure 5 as well as Figure 6As shown, there are multiple mounting components, and these mounting components are evenly distributed on both sides of the positioning device 3.

[0043] The installation assembly includes a fixing seat 6 fixed on the base plate 5 and a sleeve 301 fixed on the bottom side of the positioning device 3. A stud 7 is fixed on the fixing seat 6, the sleeve 301 is sleeved on the stud 7, and a nut 8 is threadedly connected to the stud 7.

[0044] With the positioning device 3 installed, the nut 8 presses the sleeve 301, causing the sleeve 301 to press onto the fixed seat 6.

[0045] During disassembly, unscrew nut 8, then lift positioning device 3; the sleeve 301 separates from stud 7, thus completing disassembly. During installation, connect sleeve 301 to stud 7, then tighten nut 8 on stud 7. Nut 8 presses against sleeve 301, and sleeve 301 presses against fixing seat 6, thus completing installation.

[0046] like Figures 4-6 As shown, the positioning part includes a positioning post 11 fixed to the top surface of the base plate 5 and a positioning sleeve 902 fixed to the bottom of the battery 9. The positioning post 11 and the positioning sleeve 902 are inserted into each other.

[0047] When the positioning device 3 is installed, the positioning sleeve 902 is inserted into the positioning post 11 to provide positioning for the battery 9.

[0048] The clamping part includes a first spring 12, which is sleeved on the positioning post 11.

[0049] During the installation of the positioning device 3, the first spring 12 is compressed. The elastic force of the compressed first spring 12 provides upward pressure to the battery 9, so that the electrical contact at the top of the battery 9 fits tightly with the electrical contact of the positioning device 3, thus avoiding poor contact.

[0050] like Figures 4-6 As shown, the base plate 5 is provided with an annular insert 13, and the insert 13 is provided with an annular groove along its length direction, and the sealing ring 10 is embedded in the annular groove.

[0051] After the positioning device 3 is installed, the sealing ring 10 is pressed into the insert 13 to provide a seal for the bottom opening of the mounting cavity 302, preventing water and foreign objects from entering.

[0052] A finger groove 3021 is provided on one side of the groove wall of the mounting cavity 302.

[0053] The finger slot 3021 allows for easy insertion of a finger to remove the battery 9.

[0054] like Figure 4As shown, a lever 901 is fixed to one side of the bottom of the battery 9, and the lever 901 extends into the finger groove 3021.

[0055] When removing the battery 9, the battery 9 can be removed by inserting a finger into the finger groove 3021 and turning the lever 901. The lever 901 is designed to make it easier to remove the battery 9.

[0056] like Figure 1 As shown, the top surface of the positioning device 3 is lower than the height of the corner pieces 2 at the four corners of the ship's box-type power supply 1.

[0057] When the positioning device 3 is installed on the ship's box-type power supply 1, the positioning device 3 is located in the mounting groove 4. The highest point of the positioning device 3 is not higher than the plane of the top corner piece 2 of the ship's box-type power supply 1 and does not exceed the outline of the ship's box-type power supply 1, so as not to affect the hoisting, stacking and dock transfer operations of the ship's box-type power supply 1.

[0058] like Figure 8 As shown, an inner sealing component 18 is provided inside the sealing ring 10. The inner sealing component 18 includes a corrugated folded soft sleeve 1804. The top end of the corrugated folded soft sleeve 1804 is fixed to the bottom surface of the positioning device 3. A pressure plate 1801 is fixed to the bottom end of the corrugated folded soft sleeve 1804. A sealing gasket 1802 is provided on the bottom surface of the pressure plate 1801. The pressure plate 1801 is elastically connected to the bottom surface of the positioning device 3 through a second spring 1803.

[0059] By adding an inner sealing component 18, the sealing effect of the bottom opening of the mounting cavity 302 is further improved. When the positioning device 3 is installed, the inner sealing component 18 is pressed between the bottom surface of the positioning device 3 and the base plate 5, causing the corrugated folded soft sleeve 1804 to shrink and the second spring 1803 to compress. The elastic force of the second spring 1803 causes the pressure plate 1801 and the sealing gasket 1802 to press against the base plate 5 to form a seal. Together with the seal provided by the sealing ring 10, a double sealing structure is formed.

[0060] This utility model is not limited to the above-described embodiments. Any changes made to its shape or structure fall within the protection scope of this utility model. The protection scope of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the protection scope of this utility model.
