Description

Technical Field

[0001] This invention relates to the field of water rescue technology, and in particular to a combined fire rescue device for rescuing people who have fallen into the water. Background Technology

[0002] In fire rescue operations, people falling into the water is a common emergency. When a drowning accident occurs, rescuers usually need to throw lifebuoys, life ropes and other rescue equipment to the person in the water so that they can float on the surface of the water and wait for further rescue.

[0003] Rescue equipment such as lifebuoys are usually fixed in shape and large in size, making them inconvenient to launch and carry over long distances. If they are launched directly using a launch device, their large size and high wind resistance will severely affect the launch distance and accuracy. Therefore, miniaturized equipment is more preferred.

[0004] If miniaturized equipment is used, it will be difficult to provide sufficient buoyancy and support area after the person falls into the water, thus failing to effectively ensure the safety of the person. Existing deployable rescue equipment requires manual unlocking of the deployment mechanism, which can easily lead to missed opportunities for rescue due to operational delays in emergency rescue scenarios. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, the purpose of this invention is to provide a fire rescue combination device for rescuing people who have fallen into water, which can automatically unlock and deploy its mechanism during operation.

[0006] The objective of this invention is achieved through the following technical solution:

[0007] A combined fire rescue device for rescuing people who have fallen into water includes:

[0008] A launching base, wherein the launching base is provided with a catapult mechanism;

[0009] A rescue component is slidably mounted on the launching base and supported by the ejection mechanism. The rescue component includes a first housing and a second housing, the first housing and the second housing being pivotally connected, with the pivotally connected end defined as the pivot end. The first housing has a first receiving cavity, and the second housing has a second receiving cavity, a water inlet, an unlocking cavity, and a first guide through hole. When the first receiving cavity and the second receiving cavity are engaged, a floating cavity is formed, which houses the floating component. The water inlet connects the unlocking cavity to the external environment, and the first guide through hole also connects the unlocking cavity to the external environment.

[0010] An automatic unlocking assembly includes a locking element and an unlocking element. The locking element is installed at one end relative to the pivot end, and the unlocking element is connected to the locking element and used to unlock the locking element. The locking element includes a locking sleeve and a locking rod, which cooperate to lock the first housing and the second housing. The unlocking element includes a first push block and a first float plate. The first push block abuts against the locking sleeve and is used to drive the locking sleeve to disengage from the locking rod. The first float plate is movably inserted into the unlocking cavity through a first guide hole. The first float plate is connected to the first push block so that when the water level in the unlocking cavity rises, the first float plate drives the first push block to push the locking sleeve, thereby separating the locking sleeve and the locking rod.

[0011] Furthermore, the locking component includes a first locking block and a second locking block. The first locking block is installed on the first housing, and the second locking block is installed on the second housing. The first locking block and the second locking block are spaced apart. The first locking block and the second locking block are respectively provided with a first through hole and a second through hole. The locking sleeve is slidably inserted through the first through hole and elastically connected to the first locking block. The locking rod is slidably inserted through the second through hole and elastically connected to the second locking block, so that the locking rod and the locking sleeve tend to move closer to each other.

[0012] Furthermore, the second housing has a second guide through hole, which connects the unlocking cavity to the external environment. The second guide through hole and the first guide through hole are arranged opposite each other in the horizontal direction. The unlocking component includes a second push block, a second float plate, and a telescopic rod. The second push block abuts against the locking sleeve rod. The second float plate is movably inserted into the unlocking cavity through the second guide through hole. The second push block is connected to the second float plate so that when the water level in the unlocking cavity rises, the second float plate drives the second push block to push the locking sleeve rod, thereby separating the locking sleeve rod from the locking sleeve. The second push block and the first push block are connected by the telescopic rod.

[0013] Furthermore, a torsion spring is installed at the pivot joint of the first housing and the second housing to give the swing ends of the first housing and the second housing a tendency to move away from each other.

[0014] Furthermore, the floating assembly includes a compressed air tank, an air supply pipe, and an air bladder. The compressed air tank is housed within the first receiving cavity, the air supply pipe is connected to the compressed air tank and housed within the first receiving cavity, and the two ends of the air bladder are respectively sealed and connected to the air supply pipe and the second housing. The start button of the compressed air tank is located outside the first housing.

[0015] Furthermore, multiple airbags are provided, and the multiple airbags are arranged at intervals along the length direction of the air supply pipe.

[0016] Furthermore, the launch base is pivotally connected to a take-up roller, which winds up a take-up rope, and the release section of the take-up rope is connected to the rescue assembly.

[0017] Furthermore, the bottom of the launch base is rotatably connected to a rotating seat and supported by the rotating seat.

[0018] Furthermore, the water inlet is equipped with a filter screen.

[0019] Furthermore, fluorescent markings are provided on the outer surfaces of the first and second housings.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. Based on the launch base equipped with an ejection mechanism, the rescue component is slidably mounted on the launch base and supported by the ejection mechanism. Under the action of the ejection mechanism, the rescue component can slide rapidly along the launch base and be ejected to the target water area, realizing long-distance, non-contact rescue deployment. Compared with traditional hand-thrown lifebuoys or manual wading rescue, this ejection deployment method can significantly increase the throwing distance of the rescue component, shorten the rescue response time, expand the rescue coverage area, and rescuers can complete the deployment operation from a safe position on the shore or boat, avoiding rescuers directly entering dangerous waters and reducing the risk of secondary injury or death during the rescue process. The stable initial velocity provided by the ejection mechanism can ensure the deployment accuracy of the rescue component, enabling the rescue component to reach the vicinity of the drowning person more accurately and improving the rescue success rate.

[0022] 2. Based on the pivotal connection between the first and second shells, the first and second receiving cavities cooperate to form a floating cavity, which houses the floating component. After the rescue component is unlocked, it can swing and unfold relative to each other along the pivot end. The floating cavity formed by the first and second receiving cavities opens, and the floating component exerts buoyancy within the floating cavity, forming a rescue carrier that can be grabbed or relied upon by the person in the water. The first and second shells adopt a pivotal opening and closing structure. When not unfolded, the whole is in a compact closed state, with small volume and low wind resistance, which is convenient for ejection transportation and storage. After unfolding, it forms a floating cavity with a large internal space, which can provide sufficient space for the arrangement and unfolding of the floating component and ensure buoyancy output. The floating cavity is formed by the enclosure of the first and second shells. The shells themselves also have a certain water-proof and structural support function, which can provide a stable grab and support surface for the person in the water, prevent the person in the water from falling out of the rescue component in panic, and improve the safety and reliability of the rescue carrier.

[0023] 3. The automatic unlocking component includes a locking element and an unlocking element. This automatic unlocking component uses the buoyancy of water as the unlocking power, requiring no external power supply, sensors, or manual operation. It has a simple structure and reliable operation, and can automatically trigger unlocking after the rescue component enters the water, ensuring that the rescue component can deploy in time after falling into the water. The first guide through hole provides guidance and constraint for the movement of the first float, ensuring that the first float floats smoothly in the predetermined direction, avoiding the first float from tilting or getting stuck, and improving the stability and accuracy of the unlocking action. The sleeve and locking rod are fitted together in a compact and secure manner, which can effectively withstand the vibration and impact during ejection and transportation, and prevent accidental unlocking.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0032] See Figures 1-4 A preferred embodiment of the present invention provides a fire rescue combination device for rescuing people from drowning, comprising: a launching base 1, a rescue component 3, and an automatic unlocking component 9;

[0033] Launching base 1 is equipped with ejection mechanism 2;

[0034] The rescue component 3 is slidably mounted on the launch base 1 and supported by the ejection mechanism 2. The rescue component 3 includes a first housing 301 and a second housing 302, which are pivotally connected. The pivot end of the first housing 301 and the second housing 302 is defined as the pivot end. The first housing 301 has a first receiving cavity 4, and the second housing 302 has a second receiving cavity 5, a water inlet 6, an unlocking cavity 7, and a first guide through hole 8. When the first receiving cavity 4 and the second receiving cavity 5 are engaged, a floating cavity is formed, which contains the floating component 15. The water inlet 6 connects the unlocking cavity 7 to the external environment, and the first guide through hole 8 connects the unlocking cavity 7 to the external environment.

[0035] Automatic unlocking component 9 includes a locking element 901 and an unlocking element 902. The locking element 901 is mounted at one end relative to the pivot end, and the unlocking element 902 is connected to the locking element 901 and used to unlock the locking element 901. The locking element 901 includes a locking sleeve 9011 and a locking rod 9012, which cooperate to lock the first housing 301 and the second housing 302. The unlocking element 902 includes a first push block 9021 and a first float 9022. A pusher block 9021 abuts against the locking sleeve 9011 and is used to drive the locking sleeve 9011 to disengage from the locking rod 9012; a first float plate 9022 is movably inserted into the unlocking cavity 7 through a first guide hole 8; the first float plate 9022 is connected to the first pusher block 9021 so that when the water level in the unlocking cavity 7 rises, the first float plate 9022 drives the first pusher block 9021 to push the locking sleeve 9011, thereby separating the locking sleeve 9011 and the locking rod 9012.

[0036] The working principle of this invention is as follows:

[0037] Under normal conditions, the first housing 301 and the second housing 302 are in a retracted state. After a person falls into the water, the rescue component 3 is placed in the launching base 1 and launched to the water near the person by the ejection mechanism 2. After the rescue component 3 enters the water, it enters the working state. In the working state, water enters the unlocking cavity 7 of the second housing 302 through the water inlet 6. The water level in the unlocking cavity 7 rises, the first float 9022 floats up along the first guide through hole 8 and drives the first push block 9021 to push the locking sleeve 9011, so that the locking sleeve 9011 separates from the locking rod 9012. The locking component 901 releases the lock on the first housing 301 and the second housing 302. The first housing 301 and the second housing 302 open the floating cavity formed by the first receiving cavity 4 and the second receiving cavity 5 around the pivot end. The floating component 15 exerts buoyancy, thereby forming a rescue carrier that can support the person who has fallen into the water and completes the rescue.

[0038] Obviously, based on the launch base 1 equipped with the ejection mechanism 2, the rescue component 3 is slidably mounted on the launch base 1 and supported by the ejection mechanism 2. Under the action of the ejection mechanism 2, the rescue component 3 can slide quickly along the launch base 1 and be ejected to the target water area, realizing long-distance, non-contact rescue deployment. Compared with traditional hand-thrown lifebuoys or manual wading rescue, this ejection deployment method can significantly increase the throwing distance of the rescue component 3, shorten the rescue response time, expand the rescue coverage area, and allow rescuers to complete the deployment operation from a safe position on the shore or boat, avoiding rescuers from directly entering dangerous waters and reducing the risk of secondary injury or death during the rescue process. The stable initial velocity provided by the ejection mechanism 2 ensures the deployment accuracy of the rescue component 3, enabling it to reach the vicinity of the person in the water more accurately and improving the rescue success rate. Based on the pivotal connection between the first housing 301 and the second housing 302, the first receiving cavity 4 and the second receiving cavity 5 cooperate to form a floating cavity, which houses the floating component 15. After the lock is released, the rescue component 3 can swing and unfold relative to each other along the pivot end, opening the floating cavity formed by the first receiving cavity 4 and the second receiving cavity 5. The floating component 15 then exerts buoyancy within the floating cavity, forming a rescue carrier that the person in the water can grab onto or rely on. The first housing 301 and the second housing 302 are pivotally connected. The structure features an openable / closing mechanism. When not deployed, it is in a compact, closed state, resulting in a small size and low wind resistance, facilitating ejection transport and storage. When deployed, it forms a floating cavity with a large internal space, providing ample room for the arrangement and deployment of the floating assembly 15, ensuring buoyancy output. The floating cavity is formed by the first shell 301 and the second shell 302, which also provide some water resistance and structural support, offering a stable gripping and support surface for those in the water, preventing them from detaching from the rescue assembly 3 in a panic, and improving the safety and reliability of the rescue vehicle. Based on the automatic unlocking assembly 9, which includes a locking element 901 and an unlocking element 902, this automatic unlocking... The locking assembly 9 uses the buoyancy of water as the unlocking power, requiring no external power supply, sensor, or manual operation. It has a simple structure and reliable operation, and can automatically trigger unlocking after the rescue assembly 3 enters the water, ensuring that the rescue assembly 3 can deploy in time after falling into the water. The first guide through hole 8 provides guidance and constraint for the movement of the first float 9022, ensuring that the first float 9022 floats smoothly in the predetermined direction, avoiding the first float 9022 from tilting and getting stuck, and improving the stability and accuracy of the unlocking action. The sleeve 9011 and the locking rod 9012 are fitted together in a compact and secure manner, which can effectively withstand the vibration and impact during ejection and transportation, and prevent accidental unlocking.

[0039] More preferably, the locking member 901 is provided with a first locking block 10 and a second locking block 11. The first locking block 10 is installed on the first housing 301, and the second locking block 11 is installed on the second housing 302. The first locking block 10 and the second locking block 11 are spaced apart. The first locking block 10 and the second locking block 11 are respectively provided with a first through hole 12 and a second through hole 13. The locking sleeve 9011 is slidably inserted through the first through hole 12 and elastically connected to the first locking block 10. The locking rod 9012 is slidably inserted through the second through hole 13 and elastically connected to the second locking block 11, so that the locking rod 9012 and the locking sleeve 9011 tend to move closer to each other. In this design, in the locked state, the pre-tightening force generated by the elastic connection keeps the locking sleeve 9011 and the locking rod 9012 tightly fitted together, effectively resisting the impact vibration during ejection and the bumps and swaying during transportation and storage, preventing the locking sleeve 9011 and the locking rod 9012 from accidentally loosening, and improving the reliability and stability of locking. The first locking block 10 and the second locking block 11 are independently installed on the first housing 301 and the second housing 302, respectively, facilitating the assembly, debugging, maintenance, and replacement of the locking components. The locking sleeve 9011 and the locking rod 9012 are elastically connected to the corresponding locking blocks. After unlocking, the elastic element can drive the locking sleeve 9011 and the locking rod 9012 to automatically reset to their initial positions, facilitating the re-locking after the rescue component 3 is retrieved, enabling the device to be reused and reducing operating costs. The elastic connection also provides a buffering effect during locking and unlocking, avoiding damage to components caused by rigid collisions and extending the service life of the device.

[0040] More preferably, the second housing 302 has a second guide through hole, which connects the unlocking cavity 7 and the external environment. The second guide through hole and the first guide through hole 8 are arranged opposite each other in the horizontal direction. The unlocking component 902 includes a second push block 9023, a second float plate 9024, and a telescopic rod 9025. The second push block 9023 abuts against the locking sleeve rod 9012. The second float plate 9024 is movably inserted into the unlocking cavity 7 through the second guide through hole. The second push block 9023 is connected to the second float plate 9024 so that when the water level in the unlocking cavity 7 rises, the second float plate 9024 drives the second push block 9023 to push the locking sleeve rod 9012, thereby separating the locking sleeve rod 9012 from the locking sleeve 9011. The second push block 9023 and the first push block 9021 are connected by the telescopic rod 9025. In this preferred embodiment, the second push block 9023 and the second float 9024, which are arranged relative to the first push block 9021 and the first float 9022, enable the device to be subjected to upward buoyancy regardless of whether it falls into the water from the front or the back, thereby unlocking the locking sleeve 9011 and the locking rod 9012.

[0041] More preferably, a torsion spring 14 is installed at the pivot joint of the first housing 301 and the second housing 302, so that the swinging ends of the first housing 301 and the second housing 302 tend to move away from each other. In this design, the opening driving force provided by the torsion spring 14 can overcome the friction between the housings, the resistance of the water, and any possible slight jamming, ensuring that the first housing 301 and the second housing 302 can reliably unfold after unlocking, avoiding the inability of the housings to open and causing the floating component 15 to malfunction, thus ensuring the timely realization of the rescue function; the torsion spring 14 is installed at the pivot joint, has a compact structure, does not occupy the internal space of the floating cavity, and the torque output direction of the torsion spring 14 is consistent with the swinging direction of the housing, so the driving force is transmitted directly and efficiently; the torsion spring 14 is compressed and stores energy when the housings are closed and locked, and is automatically released after unlocking, without the need for an additional power source.

[0042] Better yet, see Figure 3 As shown, the floating assembly 15 includes a compressed air tank 1501, an air supply pipe 1502, and an air bladder 1503. The compressed air tank 1501 is housed in the first receiving cavity 4. The air supply pipe 1502 is connected to the compressed air tank 1501 and is also housed in the first receiving cavity 4. The two ends of the air bladder 1503 are respectively sealed and connected to the air supply pipe 1502 and the second housing 302. The start button 16 of the compressed air tank 1501 is located outside the first housing 301. In this design, when the rescue component 3 is deployed, the person in the water or the rescuer can trigger the compressed air tank 1501 by pressing the start button 16 located outside the first housing 301. The high-pressure gas in the compressed air tank 1501 is quickly inflated into the airbag 1503 through the air supply pipe 1502, and the airbag 1503 rapidly expands to form a large floating component. The compressed air tank 1501 and the air supply pipe 1502 are housed in the first receiving cavity 4, which is effectively protected by the housing when the rescue component 3 is closed, avoiding damage from external forces during ejection and water entry. The two ends of the airbag 1503 are respectively sealed and connected to the air supply pipe 1502 and the second housing 302, so that the airbag 1503 forms a stable connection structure with the housing after deployment, preventing the airbag 1503 from detaching. At the same time, the airbag 1503 can fill the floating cavity after inflation, so that the entire rescue component 3 forms a full floating body.

[0043] More preferably, multiple airbags 1503 are provided, and the multiple airbags 1503 are spaced apart along the length of the air supply pipe 1502. In this preferred embodiment, after the multiple airbags 1503 inflate synchronously, they form multi-point buoyancy support along the length of the rescue component 3. The buoyancy is evenly distributed along the length, which enables the rescue component 3 to maintain a stable floating posture in the water, avoiding tilting, overturning, or partial sinking of the rescue component 3 due to buoyancy concentrated at one end. This improves the stability and balance of the rescue carrier in the water, providing safer and more reliable grabbing and support conditions for the person who has fallen into the water. The spaced arrangement of multiple airbags 1503 also forms a redundant safety structure. When one of the airbags 1503 leaks air due to damage or sealing failure, the remaining airbags 1503 can still inflate normally and provide buoyancy, preventing the entire rescue component 3 from losing its floating ability due to single-point failure, and enhancing the fault tolerance and safety of the rescue.

[0044] More preferably, the launching base 1 is pivotally connected to a winding roller 17, which winds up a winding rope 18. The release section of the winding rope 18 is connected to the rescue component 3. In this preferred embodiment, after the rescue is completed, the winding rope 18 can be rewound by rotating the winding roller 17, thereby pulling the rescue component 3 floating on the water surface back and retrieving it. This facilitates the reuse of the device and reduces the cost of a single rescue. The winding rope 18 can also serve as an active traction method. After the person in the water grabs the rescue component 3, the rescuer can use the winding roller 17 to wind up the winding rope 18 and gradually pull the person back to the shore or the side of the boat, thus achieving active rescue of the person in the water and preventing the person from being unable to return on their own due to exhaustion or the impact of the water current.

[0045] More preferably, the bottom of the launch base 1 is horizontally rotatably connected to a rotating seat 19 and supported by the rotating seat 19. In this preferred embodiment, the launch direction can be quickly changed by rotating the launch base 1, without the need to move the entire device or re-erect it, which greatly improves the flexibility and response speed of the launch operation, enabling rescuers to quickly and accurately target the location of the person in the water.

[0046] Better yet, see Figure 4 As shown, the water inlet 6 is equipped with a filter screen 20. In this preferred embodiment, the filter screen 20 can prevent weeds, silt, floating garbage, aquatic organisms and other debris in the water from entering the unlocking chamber 7, ensuring that the water inlet 6 is unobstructed and that the first float plate 9022 and the first push block 9021 move flexibly, so that the automatic unlocking component 9 can reliably and timely trigger unlocking in various complex water environments.

[0047] Better yet, see Figure 1As shown, fluorescent markers 21 are provided on the outer surfaces of the first housing 301 and the second housing 302. In this preferred embodiment, the rescue component 3 can absorb and release light energy through fluorescent materials in low-visibility environments such as night, dusk, fog, heavy rain, or other low-visibility conditions, emitting a conspicuous light signal. Under low-visibility conditions, it is difficult for a person in the water to spot rescue equipment of ordinary color. The fluorescent markers 21 can significantly enhance the visual recognition of the rescue component 3, enabling the person in the water to quickly find and grab onto the rescue component 3 in time, gaining valuable rescue time. The fluorescent markers 21 also facilitate rescuers to quickly locate the rescue component 3 and the person in the water on the surface, facilitating subsequent towing and retrieval and auxiliary rescue, and preventing the rescue component 3 from being lost or the location of the person in the water from being lost due to poor visibility.
