They cannot adjust their trajectory after being launched, making it difficult to accurately deliver them to the location of the person in the water. Utility Model Content

[0003] This utility model discloses a rescue projectile. By setting a drive mechanism and a control module in the rescue projectile, the position of the rescue projectile can still be adjusted after it falls into the water, so as to accurately reach the location of the person who has fallen into the water.

The control module is connected to the drive mechanism. A remote control device for enabling rescue personnel to remotely control the control module to send the control signals.

[0005] A further improvement of this utility model is that the driving mechanism is a thruster, and the thruster's thrusting direction and thrusting speed are both adjustable.

[0006] A further improvement of this utility model is that the projectile is equipped with: a detection module for determining whether the projectile is in a working state, wherein the working state is either a thrown state or a water-falling state; and an alarm module connected to the detection module, which transmits the information that the projectile is in a working state to the alarm module when the detection module determines that the projectile is in a working state, and the alarm module sends a positioning signal after receiving the information to assist rescue personnel in identifying the location of the projectile.

[0007] A further improvement of this utility model is that the working state is the water-immersed state, and the detection module includes a water pressure sensor for detecting the water pressure on the projectile and a water pressure judgment unit. The water pressure judgment unit has a preset water pressure threshold.

[0008] A further improvement of this utility model is that the working state is the ejected state, and the detection module includes a centrifugal force sensor for detecting the centrifugal force on the projectile and a centrifugal force judgment unit.

[0009] A further improvement of this utility model is that the alarm module includes a sound-emitting device; the detection module is connected to the sound-emitting device so that when the detection module determines that the projectile is in a working state, it notifies the sound-emitting device to issue an audible alarm.

[0010] A further improvement of this utility model is that the alarm module includes a light-emitting device; the detection module is connected to the light-emitting device so that when the detection module determines that the projectile is in a working state, it notifies the light-emitting device to emit a light alarm.

Attached Figure Description

[0015] Figure 1 This is the front view of the present invention; Figure 2 This is a top view of the present invention; Figure 3 This is the left view of the present invention; The components include: 1. Projectile body; 2. Friction-resistant anti-slip surface layer; 3. Air-inflated buoyancy plate; 4. Light-emitting device; 5. Drive mechanism. Detailed Implementation

[0016] like Figures 1-3 The rescue projectile shown can be installed in a projectile and launched by the projectile, and includes: a projectile body 1; Drive mechanism 5, mounted on projectile 1, for driving projectile 1 to move in water; A control module is installed on the projectile 1 to receive external control signals and control the drive mechanism 5 according to the control signals. The control module is connected to the drive mechanism 5. A remote control device used by rescue personnel to remotely control the control module and send control signals.

[0017] like Figure 2 As shown, the drive mechanism 5 is a thruster, and the thruster's thrusting direction and speed are adjustable.

[0018] In this embodiment, the maximum control distance between the control module and the remote controller is 300m, and the thruster can achieve fine-tuning of steering by ±15° left and right.

[0019] Preferably, the projectile 1 is equipped with a detection module for determining whether the projectile 1 is in a working state, which is either the ejected state or the water-falling state; the alarm module connected to the detection module transmits the information that the projectile 1 is in a working state to the alarm module when the detection module determines that the projectile 1 is in a working state. After receiving the information, the alarm module sends out a positioning signal to assist rescuers in identifying the location of the projectile.

[0020] Preferably, in one embodiment, the detection module is a water-triggering module for determining whether the projectile 1 has encountered water. When the projectile 1 encounters water, the water-triggering module determines that the projectile 1 is in a working state.

[0021] The water-triggering module in this embodiment includes a water pressure sensor and a water pressure judgment unit. The water pressure judgment unit has a preset water pressure threshold. When the water pressure sensor detects that the water pressure on the projectile 1 is greater than the water pressure threshold, the water pressure judgment unit determines that the projectile 1 is in a working state.

[0022] Preferably, in another embodiment, the detection module is a centrifugal trigger module for determining whether the projectile 1 has detached from the launcher. When the projectile 1 detaches from the launcher, the centrifugal trigger module determines that the projectile 1 is in a working state.

[0023] The centrifugal triggering module of this embodiment includes a centrifugal force sensor and a centrifugal force judgment unit. The centrifugal force judgment module has a preset centrifugal force threshold. When the centrifugal force sensor detects that the centrifugal force of the projectile 1 is greater than the centrifugal force threshold, the centrifugal force judgment unit determines that the projectile 1 is in working state.

[0024] Preferably, in another embodiment, the projectile 1 is equipped with both a water-triggering module and a centrifugal force triggering module. The two triggering modules work independently and are not dependent on each other. If the centrifugal triggering module fails due to abnormal launching force or other reasons, the water-triggering module can determine that the projectile is in working condition after it falls into the water. If the water-triggering module fails due to a minor sensor malfunction, the centrifugal triggering module can still determine that the projectile 1 is in working condition when the projectile leaves the launcher. This avoids the loss of positioning due to a single trigger failure and meets the reliability requirements of complex rescue scenarios.

[0025] like Figure 1 , Figure 3 As shown, in one embodiment, the alarm module includes a sound-emitting device; the detection module is connected to the sound-emitting device so that when the projectile 1 is in the working state, it notifies the sound-emitting device to sound an alarm. By setting the sound-emitting device, the location of the person who fell into the water can be determined.

[0026] like Figure 1 , Figure 3 As shown, in another embodiment, the alarm module includes a light-emitting device 4; the detection module is connected to the light-emitting device 4 so that when the projectile 1 is in the working state, it notifies the light-emitting device 4 to emit a light alarm.

[0027] In another embodiment, the alarm module includes both a sound-emitting device and a light-emitting device 4. When the projectile 1 is in the working state, the alarm module can emit sound and light simultaneously.

[0028] By setting up a light-emitting device 4 and a sound-emitting device, it is easier for rescuers to locate the position of the projectile 1 after it is launched, so that rescuers can more accurately control the movement of the projectile 1 through the remote control device.

[0029] like Figures 1-3 As shown, an inflatable buoyancy plate 3 is installed on the projectile 1. An inflation mechanism is installed inside the inflatable buoyancy plate 3 to inflate it when an inflation signal is received. A detection module is connected to the inflation mechanism and sends an inflation signal when it determines that the projectile 1 is in a working state. In this embodiment, the detection module connected to the inflation mechanism is only a water-triggering module. By connecting only to the water-triggering module, it is ensured that the inflation mechanism will only inflate after the projectile falls into the water. This can prevent the projectile 1 from being accidentally inflated during the air launch phase (such as when encountering rain or moisture), and ensure that the inflatable buoyancy plate 3 expands precisely only in the most needed "water phase". This prevents the inflatable buoyancy plate 3 from expanding prematurely in the air, which would increase flight resistance and affect the launch distance of the projectile 1.

[0030] In this embodiment, when the air-inflated buoyancy plate 3 is in an uninflated state, it is close to the projectile 1 and does not occupy additional space.

[0031] Better, such as Figure 3As shown, the surface of the air-inflated buoyancy plate 3 is covered with a friction-resistant anti-slip surface layer 2 to ensure that a person falling into the water can firmly grasp the air-inflated buoyancy plate 3; the friction-resistant anti-slip surface layer 2 can be coated with an anti-slip coating or pressed with anti-slip texture, and its friction coefficient must be ≥0.8.

[0032] Preferably, in this embodiment, the fixed air-inflatable buoyancy plate 3 can expand within 3-5 seconds after falling into the water, forming a buoyancy plate with stable support and a buoyancy value of 50N (fully meeting the corresponding level requirements of the national standard GB / T 32234.1-2024 "Personal Buoyancy Devices"). Moreover, the friction and anti-slip surface layer 2 on the outer surface can significantly improve the grip friction of the person falling into the water even when wet, preventing them from slipping out of their hands, thus achieving the dual function of "buoyancy support + stable grip".

[0033] Preferably, in this embodiment, the material of the projectile 1 is resistant to seawater corrosion.

[0034] This utility model has the following beneficial effects: 1. The overall structural design takes into account both lightweight and portability. The projectile body is 1 size and is compatible with conventional projectile equipment. It can be launched by existing pneumatic or manual projectiles without the need for additional modification of the launch device, thus improving the adaptability of the scenario. The buoyancy module is made of seawater corrosion resistant material, ensuring long-term reliability. 2. Through the above structural optimization, this system achieves the full-process rescue requirements of "stable grasp - safe buoyancy - reliable positioning - accurate delivery". In particular, the four-position design of the sound and light-emitting device and the integrated design of "anti-slip - buoyancy" greatly improve the reliability of functions and ease of use. In complex sea conditions, it can effectively make up for the functional shortcomings of traditional projectiles, significantly improve rescue efficiency and success rate, and strengthen the hardware support capabilities of maritime rescue equipment. 3. Through the cooperation of drive mechanism 5, control module and remote controller, the precise position adjustment of projectile 1 after it falls into the water can be achieved.

[0035] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
