DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the specification of the present application.

[0019] Please refer to the drawings of the present application Figure 1 - the drawings of the present application Figure 5 The embodiment of the present application provides a portable marine search and rescue auxiliary terminal based on Beidou navigation, which comprises a mounting frame 3, a control assembly 5, a connecting assembly 4, a supporting assembly 6, the mounting frame 3 serves as the base of the overall device and can provide support for the installation of the remaining structures, the lower surface of the mounting frame 3 is fixedly connected with an arm ring 1, the arm ring 1 is made of elastic material, when a person uses the overall device, the overall device can be worn at the position of the upper arm through the mounting frame 3, the outer wall of the arm ring 1 is fixedly connected with an air bag 2, the air bag 2 is hollow, the air bag 2 can be inflated by filling high-pressure gas into the inside of the air bag 2, the air bag 2 is made of wear-resistant material, so that the user can be driven by the air bag 2 to float on the water surface, which can improve the survival probability of the user, and the air bag 2 can extrude the arm ring 1 inward after inflation, so that the arm ring 1 can further fit the upper arm of the user, thereby further reducing the probability of falling off of the arm ring 1; The control assembly 5 is arranged in the inside of the mounting frame 3 and is used for realizing automatic alarm and automatic control; The supporting assembly 6 is arranged on the upper surface of the mounting frame 3 and is used for providing physical support for the realization of the functions of the device; The connecting assembly 4 is arranged on the upper surface of the mounting frame 3 and is used for realizing the connection of the air bag 2 and the supporting assembly 6.

[0020] The connecting assembly 4 comprises a connecting sleeve 43, the connecting sleeve 43 is a gap pipeline with open rear end and lower end, the connecting sleeve 43 is fixedly connected to the upper surface of the mounting frame 3, the inner wall of the connecting sleeve 43 is inserted with an electric control valve 41, a recess is arranged on the upper surface of the mounting frame 3 near the lower end opening position of the connecting sleeve 43, a one-way valve 42 is arranged in the recess, the one-way valve 42 is configured to allow gas to pass from top to bottom only, so as to prevent gas from overflowing, the gas passing through the one-way valve 42 will continue to flow into the inside of the air bag 2, so as to inflate the air bag 2, the bending part of the connecting sleeve 43 is designed in an arc shape, so that the gas flow can be better guided to pass through, and the resistance of the gas flow at the bending part can be reduced, and the passing speed of the gas flow can be improved.

[0021] Support component 6 includes a fixing sleeve 62, which is configured as an n-shaped plate with an opening at the bottom. A compressed gas cylinder 63 is installed on the inner wall of the fixing sleeve 62. The end of the compressed gas cylinder 63 near the solenoid valve 41 is connected to the solenoid valve 41. By moving the fixing sleeve 62, the compressed gas cylinder 63 can be connected to the solenoid valve 41. Thus, when the solenoid valve 41 is connected, the gas inside the compressed gas cylinder 63 can enter the airbag 2 through the solenoid valve 41, the connecting sleeve 43, and the one-way valve 42 to inflate the airbag 2. A buoyancy plate 65 is hinged to the outer wall of the fixing sleeve 62. The buoyancy plate 65 is connected to... The fixed sleeve 62 is elastically connected by a torsion spring 68. When the buoyancy plate 65 is unrestricted, the torsion spring 68 can drive the buoyancy plate 65 to rotate outward and open. The buoyancy plate 65 is a hollow plastic plate. When in water, it can provide buoyancy to drive the fixed sleeve 62 to move upward and emerge from the water surface. The upper surface of the fixed sleeve 62 is equipped with a transmitting antenna 64. By driving the fixed sleeve 62 to move upward and emerge from the water surface through the buoyancy plate 65, the interference of water on the transmitting antenna 64 can be reduced. At the same time, when the compressed gas cylinder 63 moves outward, it will also drive the electrically controlled valve 41 connected to it to move away from the mounting frame 3 in a synchronous manner.

[0022] Support component 6 also includes a limiting plate 61, which is fixedly connected to the upper surface of the mounting bracket 3. The limiting plate 61 can guide the movement of the fixing sleeve 62, ensuring that the fixing sleeve 62 moves horizontally and stably. At the same time, it can block the buoyancy plate 65, restricting the buoyancy plate 65 from unfolding outward. The end of the buoyancy plate 65 away from the fixing sleeve 62 is detachably connected to a locking block 66. The end face of the limiting plate 61 near the fixing sleeve 62 is provided with a locking groove 67 that matches the locking block 66. Through the cooperation of the locking block 66 and the locking groove 67, the fixing sleeve 62 can be fixed to prevent it from moving arbitrarily. When the electric control valve 41 is connected, it drives the gas from the compressed gas cylinder 63 into the interior of the airbag 2, and the airbag... The internal air pressure of airbag 2 will gradually increase, while the internal air pressure of compressed air cylinder 63 will gradually decrease. When the internal air pressure of airbag 2 exceeds the internal air pressure of compressed air cylinder 63, compressed air cylinder 63 will no longer be able to inject air into airbag 2. At this time, the gas inside compressed air cylinder 63 will accumulate inside connecting sleeve 43, causing the internal air pressure of connecting sleeve 43 to increase. In this way, the airflow will try to push the electric control valve 41 outward. The electric control valve 41 will transmit the thrust to the fixed sleeve 62 through compressed air cylinder 63. The fixed sleeve 62 will transmit the thrust to the locking block 66. In this way, the locking block 66 will break and will no longer be able to fix the fixed sleeve 62. In this way, the fixed sleeve 62 will detach from the mounting bracket 3 and move outward.

[0023] The control component 5 includes indicator lights 51, 52, and 53. Indicator lights 51, 52, and 53 are structurally identical, differing only in the color of their illumination when powered on, thus representing different information. Indicator lights 51, 52, and 53 are mounted side-by-side on the upper surface of the mounting frame 3. This side-by-side arrangement facilitates easy viewing by the operator. Electrode 2 55 and Electrode 1 54 are mounted through the front surface of the mounting frame 3. Both Electrode 2 55 and Electrode 1 54 are made of conductive materials. When both Electrode 2 55 and Electrode 1 54 are fully immersed in water, they will be interconnected through the water. The inner wall of the mounting frame 3 is equipped with a relay coil 57, a relay switch 58, a battery 56, and a transmitting element 510. The battery 56 serves as a power source to provide power for the device's operation. The transmitting element 510 can periodically send signals to control the operation of the transmitting antenna 64. The relay coil 57 and the relay switch 58 together form a complete relay to ensure continuous circuit connection.

[0024] The battery 56, electrode 54, electrode 55, relay coil 57, transmitting element 510, indicator light 52, and solenoid valve 41 are connected in series to form circuit one. When electrodes 54 and 55 are both immersed in water, circuit one will be connected, and the battery 56 will be able to supply power to the solenoid valve 41. The solenoid valve 41 will then begin to operate, connecting the compressed air cylinder 63 and the connecting sleeve 43, thus initiating the inflation operation. Simultaneously, indicator light 53 will illuminate, indicating to the operator that the device is powered on and operating normally. At the same time, one end of the relay switch 58 is connected to the relay coil 57, and the other end is connected to the battery 56. When the relay coil... After energizing 57, the relay coil 57 will drive the relay switch 58 to close, thus keeping line 1 continuously energized through the relay switch 58. This prevents the device from repeatedly disconnecting or reconnecting due to entering or leaving the water. Once the terminal is started, it will not shut down until the battery 56 is completely depleted. The operator cannot manually shut down the terminal, which prevents the terminal from being accidentally shut down due to the operator moving their limbs in the water. After use, the terminal can be recycled. By replacing the battery 56, compressed air cylinder 63, and fixing sleeve 62, it can be reused. The overall terminal has good economic efficiency.

[0025] The transmitting element 510 has a transmitting interface on its outer wall, which is connected to indicator light 53. Indicator light 53 is connected in series with transmitting antenna 64 and connected to battery 56. The transmitting structure of transmitting element 510 will be intermittently switched on and off, thus controlling transmitting antenna 64 to intermittently send signals and realize automatic distress call. At the same time, indicator light 53 will also light up intermittently to indicate to the operator that the device is transmitting. Indicator light 53 is also connected in series with indicator light 51, and indicator light 51 is connected in series with manual switch 59. Manual switch 59 is a push-button switch that will automatically turn on when pressed and automatically turn off when the operator releases it. Manual switch 59 is located on the outer wall of the mounting bracket 3 near the operator's head for easy observation. Manual switch 59 is connected to relay wire. The coils 57 are interconnected. Once the line is connected, under the premise of automatic distress call, the operator can also manually transmit signals by pressing the manual switch 59 to activate the transmitting antenna 64 and the compressed air cylinder 63 to actively connect to the battery 56. At the same time, the indicator light 51 will also light up to indicate that the manual transmission function is working properly. In this device, the transmitting antenna 64 is directly connected to the Beidou navigation system to achieve device positioning. When the line is not connected, the entire terminal is in a low-power state, which ensures that the device can maintain its function for a long time when not in use and can improve the device's effective time. When wearing the terminal, the operator should wear it as close to the base of the upper arm as possible to prevent the terminal from interfering with the operator's movement and to prevent the terminal from falling off the operator's upper arm.

[0026] Working principle: When the terminal falls into the water with the personnel, the first electrode 54 and the second electrode 55 on the mounting frame 3 are completely immersed in the water. The circuit is connected through the water, and the first line powered by the storage battery 56 is activated. At this time, the electric control valve 41 connects the compressed air cylinder 63 and the connecting sleeve 43. The high-pressure gas in the compressed air cylinder 63 is injected into the air bag 2 through the connecting sleeve 43 and the one-way valve 42, causing the air bag 2 to expand and generate buoyancy. At the same time, the relay coil 57 is energized and drives the relay switch 58 to close, ensuring that the first line is continuously energized and avoiding functional interruption due to repeated entry and exit of the equipment from the water.

[0027] After the airbag 2 is inflated, its internal air pressure exceeds the air pressure of the compressed air cylinder 63. The gas accumulates in the connecting sleeve 43 and pushes the electric control valve 41, which in turn drives the fixed sleeve 62 to move through the compressed air cylinder 63. This causes the locking block 66 to break and disengage from the locking slot 67. After the fixed sleeve 62 is detached from the mounting bracket 3, the torsion spring 68 drives the buoyancy plate 65 to unfold. The buoyancy of the hollow plastic plate lifts the transmitting antenna 64 on the fixed sleeve 62 out of the water, reducing the interference of the water body on the signal. The transmitting element 510 controls the transmitting antenna 64 to intermittently send Beidou navigation and positioning signals to realize automatic distress call. At the same time, the user can activate the manual transmission function by pressing the manual switch 59. With the status prompts of indicator lights 51 and 53, the distress call function can be stably and effectively activated.
