Abstract
Description
Technical Field
[0001] This invention belongs to the technical field of water rescue equipment, specifically referring to a water rescue inflation device with an automatic alarm function. Background Technology
[0002] Overwater accidents occur frequently during water-based operations, recreation, or navigation. Existing water rescue equipment typically uses manual rope pulling or hydrostatic release devices to trigger inflation. However, existing rescue devices have the following shortcomings: they lack early audible and visual alarm functions, often only providing buoyancy after the airbag is inflated, and in nighttime or poor visibility conditions, it is difficult to quickly spot the person in the water; the alarm methods are limited, usually relying on the person in the water actively calling for help or the passive reflective strips, lacking active flashing lights and high-decibel alarm sounds; some devices cannot recognize and alarm when the user loses control of their body (such as cramps or unconsciousness causing changes in body position) but has not yet fully sunk into the water; and relying solely on electronic alarm systems is unreliable, lacking mechanical or pneumatic backup alarm methods if the circuit fails upon contact with water.
[0003] Therefore, there is an urgent need to design a life-saving device that can realize multi-dimensional sound and light alarms, has dual protection of circuit and air circuit, and can respond in stages according to the situation of falling into the water. Summary of the Invention
[0004] To address the aforementioned technical problems and overcome the shortcomings of existing technologies, this invention provides a water rescue inflation device with an automatic alarm function, aiming to solve the problems of existing rescue equipment having a single alarm method, lacking early active alarm and dual protection mechanisms.
[0005] The technical solution adopted in this invention is as follows: This solution provides a water rescue inflation device with automatic alarm function, including an airbag, a strap connecting the airbags together, and a main unit fixed on the strap.
[0006] The main unit includes a housing. A waterproof battery is fixedly installed on the bottom surface of the inner wall of the housing. A spring box is fixedly installed on the side wall of the housing. A spring shaft and a winding ratchet are rotatably installed inside the spring box. The spring shaft and the winding ratchet are connected in a driving connection. A main gear is coaxially fixedly installed on the upper wall of the spring shaft. The spring shaft passes through the spring box and is coaxially fixedly connected to the main gear. A pawl is rotatably installed on the side wall of the housing. An electromagnet is also fixedly installed on the side wall of the housing. The winding ratchet and the pawl abut against each other, and the pawl and the electromagnet are magnetically attracted to each other.
[0007] A high-brightness LED and an alarm are fixedly installed on the side wall of the housing, and a light-transmitting window is fixedly installed on the upper wall of the housing; a rotating light shield is rotatably installed inside the side wall of the housing, and the rotating light shield covers the outside of the high-brightness LED; a rectangular groove is opened on the side wall of the rotating light shield; a secondary gear is coaxially fixedly installed on the upper wall of the rotating light shield, and the secondary gear meshes with the main gear for transmission.
[0008] A release shell is fixedly mounted on the bottom wall of the outer casing. A puncture seat is slidably mounted inside the release shell, and a puncture needle is fixedly mounted at the center of the puncture seat. An inflation spring connects the release shell and the puncture seat. A water-soluble sheet is disposed between the puncture seat and the inner wall of the release shell. The water-soluble sheet resists the elastic force of the inflation spring and limits the puncture seat. An inflation bottle is fixedly mounted on the side wall of the outer casing. A diversion cap is fixedly mounted at the mouth of the inflation bottle. The needle tip of the puncture needle is movably mounted inside the diversion cap. An inflation conduit and a sound-emitting conduit are connected to the diversion cap. A diving whistle is fixedly mounted on the outer wall of the outer casing. The inflation conduit communicates with the airbag, and the sound-emitting conduit communicates with the diving whistle. The waterproof battery is electrically connected to the high-brightness LED, the alarm, and the electromagnet. A trigger component for detecting trigger signals is provided in the circuit, and the trigger component is mounted on the outer casing.
[0009] As a preferred embodiment of the present invention, the triggering component includes a water conductive probe fixedly disposed on the lower wall of the housing, and the water conductive probe is connected to the circuit.
[0010] As another preferred embodiment of the present invention, the triggering component includes a gravity pendulum rotatably disposed on the side wall of the outer shell, an attitude contact fixedly disposed at the inner end of the gravity pendulum located in the outer shell, and a conductive ring fixedly disposed on the side wall of the outer shell and coaxially sleeved on the outside of the gravity pendulum; the attitude contact and the conductive ring are in contact and cooperate to conduct the circuit.
[0011] Compared with the prior art, the beneficial effects of the present invention are:
[0012] (1) This invention achieves a strong sound and light warning in the early stage of falling into water by setting up a physical flashing and electronic alarm driven by a mechanical spring;
[0013] (2) The present invention first triggers the sound and light alarm in the early stage of falling into the water or when the posture is abnormal to attract the attention of the rescuer; as time goes by (the water-soluble tablet dissolves), the inflation and pneumatic alarm are activated to avoid accidental triggering, which not only wastes the gas cylinder but may also affect the action;
[0014] (3) By setting up a dual sound-emitting device of electronic alarm and pneumatic diving whistle, even if the circuit is damaged and fails in seawater, the gas released from the gas cylinder can still drive the diving whistle to emit a piercing whistle, ensuring the issuance of distress signals.
[0015] (4) The present invention, through the design of a gravity pendulum, can provide an early warning when a person is in a drowning posture (vertical), which is superior to the single water-triggering method. Attached Figure Description

[0024] The accompanying drawings are provided to further illustrate the invention and form part of the specification. They are used together with the embodiments of the invention to explain the invention and do not constitute a limitation thereof. Detailed Implementation
[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0026] Example 1: Please refer to Figures 1-5 This embodiment provides a water rescue inflation device with automatic alarm function, including an airbag 1, a strap 2 connecting the airbags 1 together, and a main unit 3 fixed on the strap 2.
[0027] The main unit 3 includes a housing 10, and a waterproof battery 11 is fixedly installed on the bottom surface of the inner wall of the housing 10. A spring barrel 20 is fixedly installed on the side wall of the housing 10. The spring barrel 20 contains an energy-storing spring. A spring shaft 22 and a winding ratchet 21 are rotatably installed inside the spring barrel 20. The winding ratchet 21 is used to lock the spring in one direction for energy storage. A pawl 24 is rotatably installed on the side wall of the housing 10, and an electromagnet 25 is fixedly installed on the side wall of the housing 10. One end of the pawl 24 abuts against the winding ratchet 21, and the other end corresponds to the position of the electromagnet 25. When the electromagnet 25 is energized and generates magnetic force, it can attract the pawl 24 to rotate, causing the pawl 24 to disengage from the winding ratchet 21. A main gear 23 is coaxially fixedly installed on the upper wall of the spring shaft 22. When the spring releases energy, the spring shaft 22 drives the main gear 23 to rotate.
[0028] Regarding the alarm display, an alarm 30 and a high-brightness LED 31 are fixedly installed on the side wall of the housing 10, and a light-transmitting window 12 is fixedly installed on the upper wall of the housing 10. A rotating light shield 32 is rotatably installed on the inner side wall of the housing 10, covering the high-brightness LED 31. The side wall of the rotating light shield 32 has several rectangular slots 33. A secondary gear 34 is coaxially fixedly installed on the upper wall of the rotating light shield 32, and the secondary gear 34 meshes with the main gear 23 for transmission.
[0029] Regarding trigger detection, a triggering component is provided on the lower wall of the outer casing 10. In this embodiment, the triggering component is a water-sensing structure, and the triggering component is a water-conducting probe 13 fixedly disposed on the lower wall of the outer casing 10. The waterproof battery 11 is electrically connected to the high-brightness LED 31, the alarm 30, the electromagnet 25, and the water-conducting probe 13 to form a circuit.
[0030] Regarding inflation and release, a rectangular release shell 40 is fixedly installed on the bottom wall of the outer shell 10. A puncture seat 41 is slidably installed inside the release shell 40, and a puncture needle 42 is fixedly installed at the center of the puncture seat 41. An inflation spring 43 is fixedly installed on the inner wall of the release shell 40. One end of the inflation spring 43 is connected to the release shell 40, and the other end is connected to the puncture seat 41. A water-soluble sheet 44 is engaged between the puncture seat 41 and the inner wall of the release shell 40. Under normal conditions, the water-soluble sheet 44 stretches and expands the inflation spring 43 and restricts the movement of the puncture seat 41.
[0031] An inflation cylinder 50 is fixedly installed on the side wall of the outer casing 10. A diversion cap 51 is fixedly installed at the mouth of the inflation cylinder 50. The needle tip of the puncture needle 42 extends movably into the diversion cap 51. An inflation conduit 52 and a sound-emitting conduit 53 are fixedly connected to the diversion cap 51. A diving whistle 54 is fixedly installed on the outer wall of the outer casing 10. The inflation conduit 52 is connected to the airbag 1, and the sound-emitting conduit 53 is connected to the diving whistle 54.
[0032] The specific usage process of this solution is as follows:
[0033] First, before use, secure the airbag 1 and main unit 3 with the straps 2. In the early stages of a person falling into the water or when the main unit 3 is splashed with liquid, the water-conducting probe 13 conducts electricity upon contact with water, closing the circuit. The waterproof battery 11 powers the alarm 30, electromagnet 25, and high-brightness LED 31. At this time, the alarm 30 sounds; the high-brightness LED 31 emits a continuous light; the electromagnet 25 is energized, generating a magnetic force that attracts the pawl 24, causing it to disengage from the upper ratchet 21. The energy from the spring in the mainspring barrel 20 is released, driving the mainspring shaft 22 to rotate the main gear 23, which in turn drives the secondary gear 34 and the rotating light shield 32 to rotate at high speed. The light emitted by the high-brightness LED 31 intermittently passes through the rectangular slot 33 on the rotating light shield 32 and is projected through the light-transmitting window 12, forming a high-frequency flashing physical light signal to attract the attention of rescuers.
[0034] A few seconds after falling into the water, the water-soluble tablet 44 dissolves completely due to immersion, losing its restraining effect on the puncture seat 41. The inflatable spring 43 quickly contracts and resets, causing the puncture seat 41 and puncture needle 42 to move upward rapidly, piercing the sealing film at the mouth of the gas cylinder 50. The gas cylinder 50 releases high-pressure gas into the diversion cap 51. Most of the gas enters the airbag 1 through the inflation conduit 52, inflating it to generate buoyancy; a small portion of the gas flows into the diving whistle 54 through the sound-emitting conduit 53, emitting a piercing whistle as a mechanical backup in case the electronic alarm fails.
[0035] Example 2: This example is based on Example 1, but differs in that a triggering component is provided on the side wall of the outer shell 10. In this example, the triggering component is an attitude-sensing triggering structure. The triggering component includes a gravity pendulum 60 rotatably mounted on the side wall of the outer shell 10. An attitude contact point 61 is circumferentially fixed at the end of the gravity pendulum 60 located inside the outer shell 10. A conductive ring 62 is fixedly mounted on the side wall of the outer shell 10. The conductive ring 62 is coaxially sleeved on the outside of the gravity pendulum 60, and the attitude contact point 61 can contact and conduct electricity with the conductive ring 62. Furthermore, a water-soluble waterproof paper sheet 63 is wrapped around the outside of the release shell 40.
[0036] Please see Figures 1-7 In this embodiment, the user carries the main unit 3 on their back. In a normal lying position, such as during swimming practice, the gravity pendulum 60 maintains a specific angle under the action of gravity or buoyancy, and the posture contact 61 separates from the conductive ring 62, breaking the circuit. When the user experiences cramps, unconsciousness, or drowning, causing their body posture to change from horizontal to vertical and submerged in water, the gravity pendulum 60 rotates relative to the outer shell 10, causing the posture contact 61 to contact the conductive ring 62. The circuit is then connected, triggering the alarm 30 and the rotating light shield 32 to flash, providing an early warning. If the initial alarm does not result in rescue, as the immersion time increases, the external water-soluble waterproof paper 63 dissolves, and water flows into the release shell 40, dissolving the water-soluble sheet 44. This triggers the release of the inflatable spring 43 and the puncture needle 42 to puncture the air cylinder 50, inflating the airbag 1 and activating the diving whistle 54.
[0037] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
