Description

Technical Field

[0001] The utility model relates to the field of a ship distress rescue device, in particular to a rescue device with a multi-stage transmitter. Background Art

[0002] The marine environment is complex and ever-changing, and the safety risks of ships operating at sea are high. Typhoons, huge waves, and reefs are all major threats to ship navigation. In addition, with the increasing development of the ocean, the number of ships operating at sea is also increasing, and there are hidden dangers to ship traffic safety. Cases of ship collisions leading to ship capsizing and sinking are common. If a ship is in distress and no rescue is provided in a timely manner, the consequences will be very serious. When a ship is in distress, the ship's emergency rescue equipment can send a distress signal to the emergency rescue system. The maritime emergency command center will notify professional search and rescue forces or ships near the scene to come to the rescue. The use of emergency rescue equipment can minimize the response time of search and rescue forces to launch rescue operations, thereby minimizing the loss of life and property caused by accidents.

[0003] A multi-stage LINC (Linear Amplification with Nonlinear Components) transmitter is a specialized communications transmitter designed to meet linearity requirements while improving power efficiency. It primarily comprises a multi-stage signal separator, a phase modulation module, a predistorter, a mixer, an upconverter, and a radio frequency (RF) module. These components work together to convert the input signal into a phase signal. Through the synthesis of phase modulation and envelope signals, they ultimately generate an efficient RF signal for transmission.

[0004] Currently, most small fishing vessels are rarely equipped with advanced emergency distress systems due to economic reasons. Furthermore, these small vessels often have weak safety features and face more complex navigation situations, making collisions more likely and dangerous. Therefore, developing a simple, low-cost, and automatically triggered distress device is crucial for protecting the lives and property of fishermen. Utility Model Content

The strain sensor includes a base plate horizontally spaced at the bottom of the fixed block, and an extension plate is vertically provided on the base plate. The extension plate is inserted into the limit gap. In a normal state, a gap is left between the extension plate and the fixed block. Strain gauges are provided on the base plate and the extension plate. The strain sensor is electrically connected to the controller inside the shell as a sensor module.

[0008] On the basis of the above technical solution, the shell is a rectangular structure, and the mounting seats are arranged at the four corners of the shell.

[0009] On the basis of the above technical solution, the mounting seat is provided with a mounting hole with a threaded hole structure for matching with bolts to connect with the ship structure.

[0029] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Combine Figure 1-4 This embodiment discloses a distress signal device with a multi-stage transmitter, including a housing 1, a digital display screen 2, a limiter 3 and a strain sensor 4, which is intended to meet the needs of some small ships for transmitting distress signals in collision accidents at low cost and stable operation. Figure 6The distress device includes a controller, which is electrically connected to a power module, a sensor module, a wireless communication module, a storage module, an alarm module, and a multi-level warning module. The wireless communication module includes a multi-level LIN NC transmitter (for details, please refer to the relevant content in the prior art such as patent CN101110595A), which enables the wireless communication module to operate normally with low power, reducing purchase and maintenance costs, and is conducive to meeting the needs of some small ships for low-cost and stable operation of collision accident distress signal transmission. It should be noted that the various functional modules of the distress device are all prior art, and their specific structure and working principle will not be repeated here. Those skilled in the art can select and implement them from the prior art according to actual operation conditions.

[0031] The main innovation of this embodiment lies in the following: the rescue device comprises a rectangular housing 1 with mounting brackets 11 for connecting to the vessel's structure, located at the four corners of the housing 1. These brackets 11 are provided with threaded mounting holes 12 for bolt connection to the vessel's structure. The housing 1 is specifically manufactured using a one-piece injection molding process, with detachable upper and lower components. Sealing gaskets are installed at the joints to seal the interior and protect the internal electronic components.

[0032] The top of the housing 1 is provided with a digital display screen 2 for displaying the operating status and parameters of the device. The housing 1 is provided with an inner cavity 13 inside which the controller is arranged.

[0033] Furthermore, a flange-structured abutment platform 14 is provided at the bottom of the shell 1. The abutment platform 14 is a rectangular ring structure. A detection cavity 15 is provided inside the abutment platform 14. A limiter 3 and a strain sensor 4 are provided in the detection cavity 15 for collecting signals of ship collision.

[0034] Specific, combined Figure 3 and Figure 4 The position limiting member 3 is composed of two laterally spaced fixed blocks, namely a first fixed block 31 and a second fixed block 32. The first and second fixed blocks 31 and 32 are both rectangular in structure, and the adjacent sides and bottom sides of the first and second fixed blocks 31 and 32 are flat end surfaces. A position limiting gap 33 is defined between the two fixed blocks.

[0035] The strain sensor 4 includes a base plate 41 horizontally spaced at the bottom of the fixed block, one end of which is a fixed end connected to the inner wall of the abutment platform 14, and the fixed end is electrically connected to the controller inside the shell 1. The other end of the base plate 41 is a free end close to the limit member 3. An extension plate 42 is vertically arranged on the base plate 41, so that the main body of the strain sensor 4 has an inverted "T"-shaped longitudinal cross-sectional profile. The extension plate 42 is inserted into the limit gap 33. Under normal conditions, there is a gap between the extension plate 42 and the fixed block. The gap is selected according to actual design parameters. When a ship collision occurs, the short-term violent vibration generated by the hull will cause the base plate 41 and / or the extension plate 42 to frequently contact the limit member 3, causing the main body of the strain sensor 4 to deform. Strain gauges are provided on the base plate 41 and the extension plate 42. The strain sensor 4 is electrically connected to the controller inside the shell 1 as a sensor module, and uses the resistance change of the strain gauge to capture signals, thereby sending corresponding instructions to the controller to run the corresponding program.

[0036] It should be noted that there is a gap between the extension plate 42 and the inner side wall of the abutment groove, which allows a cantilever structure to be formed without affecting the basic structure of the free end of the strain sensor 4, thereby improving the sensing sensitivity of the strain sensor 4.

[0037] During the specific implementation process, the strain sensor 4 uses its unique structural design to accurately and stably detect collisions. The signal is sent to the controller, which compares and calculates the duration, frequency and intensity of the sensing signal with the threshold data, and generates corresponding instructions to the graded warning module. The graded warning module generates different types of warning signals according to the signal type, and simultaneously generates an alarm instruction and sends it to the alarm module, which is then sent to the remote server via the wireless communication module. The storage module records the operating parameters, and the power module provides power for the operation of each module.

[0038] In another embodiment, if Figure 5 As shown, in order to make the matching direction between the limiter 3 and the strain sensor 4 more multi-dimensional, expansion plates 43 are vertically provided on both sides of the extension plate 42, and there is a distance between the expansion plate 43 and the side wall of the fixed block. Therefore, the strain sensor 4 and the limiter 3 have a matching relationship in the front-back, left-right, and up-down directions, making the signal detection more comprehensive and reliable.

[0039] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
