Description

Technical Field

[0001] This invention relates to the field of water rescue equipment technology, specifically to a water rescue device for fire rescue. Background Technology

[0002] Life rafts and lifeboats are common water rescue equipment used in fire and rescue operations. They are specialized equipment and tools for water rescue missions, designed to help rescuers carry out rescue and relief work in aquatic environments. They can provide a safe floating platform for people to avoid danger and wait for rescue.

[0003] Existing lifeboats are vessels with autonomous propulsion capabilities. They are typically rigid in structure, providing greater stability and comfort. They can accommodate multiple passengers and are equipped with comfortable seats and wave-damping facilities, allowing passengers to remain relatively safe and comfortable in harsh sea conditions. Lifeboats are usually equipped with necessary life-saving equipment such as life rings, food, water, medical kits, and communication equipment so that passengers can receive necessary support during a rescue. Lifeboats are autonomously propelled and controlled through their own power systems, such as oars and engines, to find safe areas or escape dangerous areas.

[0004] However, during lifeboat rescues, the need to get close to the victims to manually throw lifebuoys presents two drawbacks. First, due to limited human strength, the lifebuoy is thrown only a short distance, requiring the lifeboat to get very close. The waves created by the lifeboat during this approach are detrimental to the rescue. Second, manually throwing lifebuoys is prone to deviations in direction, potentially missing the optimal rescue window. Third, some victims, due to excessive panic, are unable to calmly use the lifebuoy, significantly increasing the difficulty of the rescue and requiring external force to lift them. Both manual rescue and lifelines pose safety hazards. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a water rescue device for fire rescue, which can accurately throw a lifebuoy in a specific direction to improve rescue efficiency, and is equipped with a special rescue net to quickly lift the victim from underwater, thereby increasing the rescue success rate and reducing rescue risks.

[0008] As an improvement, the fixed main board is provided with a bracket on the side near the life ring placement rack. A rotating shaft is fixedly connected to one end of the bracket near the sliding block. The rotating shaft is rotatably connected to the ejection switch plate. A stop block is provided on the sliding plate. A locking block that cooperates with the stop block is provided at the bottom of the ejection switch plate. A trapezoidal end that cooperates with the trapezoidal fixing block is provided at one end of the ejection switch plate near the trapezoidal fixing block.

[0009] As an improvement, racks are provided on both sides of the sliding plate, and gears that cooperate with the racks are provided on both sides of the fixed main plate. The two gears are fixedly connected to the drive shafts of the two drive motors.

[0010] As an improvement, the support rod includes a main rod, on which a first connecting rod is provided. The first connecting rod is provided with a plurality of evenly distributed annular grooves. The triangular flag includes a rotating sleeve that cooperates with the first connecting rod. The rotating sleeve is provided with a hemispherical groove that cooperates with the annular groove. A ball bearing is provided between the hemispherical groove and the annular groove. A flag is fixedly connected to one side of the rotating sleeve.

[0011] As an improvement, the double-cylinder anti-sinking shell includes a double-cylinder shell, the double-cylinder shell is provided with a plurality of evenly distributed baffles, the double-cylinder shell is provided with a plurality of first air chambers separated by baffles, and the anti-sinking guide chamber includes an anti-sinking guide shell, the anti-sinking guide shell is provided with a second air chamber.

[0012] As an improvement, the main frame includes a main frame body, which has two symmetrical through holes. Two symmetrically mounted shaft brackets are provided on one side of the main frame body, and the shaft brackets are provided with strip-shaped shaft grooves.

[0013] As an improvement, the net rescue device includes a first electric telescopic rod fixedly installed on the main frame. The first electric telescopic rod passes through the main frame through a through hole. An L-shaped connecting rod that mates with the main frame is fixedly connected to the bottom of the first electric telescopic rod. A connecting shaft that can slide and rotate within a strip-shaped shaft groove is provided on the shaft frame. A second connecting rod is fixedly connected to one end of the connecting shaft.

A flexible net is provided between the two first net fixing devices and the two second net fixing devices.

[0014] With the above structure, the present invention has the following advantages:

[0015] 1. Equipped with a lifebuoy ejection device, through the cooperation of a sliding plate, sliding block, spring, ejection switch plate and drive motor, the sliding block can quickly eject the lifebuoy. Compared with the traditional manual throwing of the lifebuoy, the ejection direction is more accurate, avoiding the situation where the direction of manual throwing is greatly deviated and thus missing the best rescue time. The ejection distance is farther than that of manual throwing, which can keep the equipment at a certain distance from the victim, thereby preventing the victim from being choked by water or other secondary injuries caused by the rescue equipment being close to the victim.

[0016] 2. Equipped with a net rescue device, through the cooperation of the first electric telescopic rod, L-shaped connecting rod, connecting shaft, second electric telescopic rod, soft net and main frame, when the victim is too panicked or incapacitated to save themselves, the soft net can be used to lift the victim to a certain extent. Compared with manual rescue, this reduces the rescue risk and increases the rescue success rate.

[0017] 3. By forming several first air chambers separated by partitions inside the double-cylinder shell, and a second air chamber inside the anti-sinking guide chamber, the entire device forms multiple independent air chambers, which greatly improves the stability after being impacted and enhances safety.

[0018] 4. Through the cooperation between the rotating sleeve, main rod and rotating ball, the tail end of the flag is always opposite to the direction of travel of the equipment during the operation, so that the remote rescue personnel can clearly observe the direction of travel of the equipment, and the wind direction on the water surface can be observed after the equipment stops on the water surface.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings.

[0031] Combined with appendix Figure 1 and attached Figure 9 A water rescue device for firefighting and rescue includes a double-cylinder anti-sinking shell 1, wherein the double-cylinder anti-sinking shell 1 comprises a double-cylinder shell 101, and the double-cylinder shell 101 is provided with a plurality of evenly distributed partitions 102. The double-cylinder shell 101 is provided with a plurality of first air chambers 103 separated by the partitions 102. Anti-sinking guide chambers 2 are fixedly connected to both ends of the double-cylinder anti-sinking shell 1. The anti-sinking guide chamber 2 comprises an anti-sinking guide shell 201, and the anti-sinking guide shell 201 is provided with a second air chamber 202.

[0032] The double-cylinder shell 101 has several evenly distributed partitions 102 inside, which form several first air chambers 103 separated by the partitions 102, and a second air chamber 202 inside the anti-sinking guide chamber 2. This makes the whole device form multiple independent air chambers, which greatly improves the stability after being impacted and enhances safety.

[0033] Combined with appendix Figure 7 and attached Figure 10The double-cylinder anti-sinking shell 1 is externally fixedly connected to a main frame 3. The main frame 3 includes a main frame body 301, which has two symmetrical through holes 304. Two symmetrically installed shaft brackets 302 are located on one side of the main frame body 301, and each shaft bracket 302 has a strip-shaped shaft groove 303. A net-dropping rescue device 9 is located below the main frame 3. The net-dropping rescue device 9 includes a first electric telescopic rod 901 fixedly installed on the main frame body 301. The first electric telescopic rod 901 passes through the main frame body 301 via the through holes 304. An L-shaped connecting rod 902 that mates with the main frame body 301 is fixedly connected to the bottom of the first electric telescopic rod 901. A connecting shaft 903 that can slide and rotate within the strip-shaped shaft groove 303 is provided on the shaft bracket 302. A second connecting rod 904 is fixedly connected to one end of the connecting shaft 903. 04. One end away from the connecting shaft 903 is rotatably connected to the L-shaped connecting rod 902. The other end of the connecting shaft 903 is fixedly connected to an electric telescopic rod seat 905. A first net fixing device 908 is provided at the end of the electric telescopic rod seat 905. A second electric telescopic rod 906 is provided on the electric telescopic rod seat 905. A second net fixing device 909 is provided at the end of the second electric telescopic rod 906 away from the electric telescopic rod seat 905. A flexible net 907 is provided between the two first net fixing devices 908 and the two second net fixing devices 909.

[0034] This structure controls the extension length of the second electric telescopic rod 906. When the second electric telescopic rod 906 is at its longest, the flexible landing net 907 is fully open; when the second electric telescopic rod 906 is at its shortest, the flexible landing net 907 is fully closed. It also controls the extension length of the first electric telescopic rod 901. When the first electric telescopic rod 901 extends from its shortest length, the flexible landing net 907 rotates upwards around the connecting shaft 903. When the first electric telescopic rod 901 shortens from its longest length, the flexible landing net 907 rotates downwards around the connecting shaft 903. When a person in distress cannot save themselves using a lifebuoy, the flexible landing net 907 can lift them up, reducing rescue risks and increasing the success rate of the rescue.

[0035] Combined with appendix Figure 2 Appendix Figure 3 and attached Figure 5One end of the main frame 3 is fixedly connected to a lifebuoy ejection device 6. The lifebuoy ejection device 6 includes a fixed main plate 601 fixedly connected to the main frame 3. A sliding plate 602 is slidably connected to the fixed main plate 601. A sliding block 603 is slidably connected to the sliding plate 602. A trapezoidal fixing block 604 is fixedly installed on the sliding plate 602. A limiting slide rod 605 slidably connected to the sliding block 603 is fixedly installed inside the trapezoidal fixing block 604. The sliding block 603 is provided with a limiting slide rod 605. The five-part limiting sliding hole 617 is provided. A spring 606 is provided between the trapezoidal fixing block 604 and the sliding block 603 and is sleeved on the limiting sliding rod 605. A launch switch plate 609 is provided above the sliding block 603 to allow the sliding block 603 to charge and launch. Drive motors 612 are provided on both sides of the fixed main board 601 to control the left and right movement of the sliding plate 602. A life ring placement rack 613 is fixedly connected to the end of the fixed main board 601 away from the main frame 3. A life ring 614 is provided on the life ring placement rack 613.

[0036] Two symmetrical drive motors 612 control the left and right movement of the sliding plate 602. When the sliding plate 602 moves from the direction of the main frame 3 towards the direction of the life ring placement frame 613, the sliding block 603 moves with the sliding plate 602. When the sliding block 603 contacts the ejection switch plate 609, the sliding block 603 is blocked by the ejection switch plate 609. At this time, the sliding block 603 continues to move, thereby compressing the space of the spring 606, thus causing the spring 606 to store force. When the sliding plate 602 continues to move and the ejection switch... When plate 609 makes contact, ejector switch plate 609 lifts up and disengages from sliding block 603. At this time, sliding block 603 is subjected to the elastic force of spring 606 and quickly moves from the direction of main frame 3 to the direction of life ring placement frame 613 to eject the life ring 614. This prevents the life ring 614 from being missed due to directional deviation when manually thrown. In addition, when ejecting the life ring 614, this device can maintain a distance from the victim and prevent the risk of the victim being choked by water due to waves caused by this device.

[0037] Combined with appendix Figure 3 Appendix Figure 5 and attached Figure 6 The fixed main board 601 has a bracket 607 on the side near the life ring holder 613. The bracket 607 is fixedly connected to a rotating shaft 608 at one end near the sliding block 603. The rotating shaft 608 is rotatably connected to the ejection switch plate 609. The sliding plate 602 has a stop block 611. The bottom of the ejection switch plate 609 has a locking block 610 that cooperates with the stop block 611. The ejection switch plate 609 has a trapezoidal end 618 that cooperates with the trapezoidal fixing block 604 at one end.

[0038] With this structure, during the sliding process of the sliding block 603 moving from the main frame 3 towards the life ring placement frame 613, after the stop block 611 on the sliding block 603 contacts the locking block 610 at the lower end of the ejector switch plate 609, the travel trajectory can be restricted by the ejector switch plate 609, causing the sliding plate 602 and the sliding block 603 to move relative to each other, thereby causing the spring 606 to store force. After the trapezoidal end 618 at one end of the ejector switch plate 609 contacts the trapezoidal fixing block 604 on the sliding plate 602, the trapezoidal fixing block 604 lifts the trapezoidal end 618 upward, causing the sliding block 603 to disengage from the ejector switch plate 609 and quickly eject.

[0039] Combined with appendix Figure 3 and attached Figure 4 The sliding plate 602 is provided with racks 615 on both sides, and the fixed main plate 601 is provided with gears 616 on both sides that cooperate with the racks 615. The two gears 616 are fixedly connected to the drive shafts of the two drive motors 612.

[0040] This structure enables two drive motors 612 to repeatedly move the sliding plate 602 from the main frame 3 towards the life ring placement rack 613.

[0041] A support rod 7 is fixedly connected above the main frame 3. A triangular flag 8 is rotatably connected to the support rod 7. The support rod 7 includes a main rod 701. A first connecting rod 702 is provided on the main rod 701. A plurality of evenly distributed annular grooves 703 are provided on the first connecting rod 702. The triangular flag 8 includes a rotating sleeve 801 that cooperates with the first connecting rod 702. A hemispherical groove 802 that cooperates with the annular groove 703 is provided inside the rotating sleeve 801. A ball bearing 803 is provided between the hemispherical groove 802 and the annular groove 703. A flag 804 is fixedly connected to one side of the rotating sleeve 801.

[0042] With this structure, since the rotating sleeve 801 and the main rod 701 are rotatably connected through the ball bearing 803, the tail end of the flag 804 is always opposite to the direction of travel of the equipment during the operation. This allows remote rescue personnel to clearly observe the direction of travel of the equipment and the wind direction on the water surface after the equipment stops.

[0043] An infrared night vision device 11 is fixedly connected to the top of the support rod 7. A 360° wireless camera 10 is fixedly installed below the infrared night vision device 11. Electric telescopic frames 4 are fixedly connected to both sides of the main frame 3. Trapezoidal floats 12 are fixedly connected to one end of the two electric telescopic frames 4. Spiral propulsion devices 5 are fixedly installed at the lower ends of the two trapezoidal floats 12.

[0044] With an infrared night vision device 11 and a 360° wireless camera 10, remote control personnel can clearly observe the situation at the disaster site. The electric telescopic frame 4 between the two sides of the main frame 3 and the trapezoidal float 12 allows the equipment to be adjusted according to the width of the water. Two independent spiral propulsion devices 5 can ensure the forward, backward and rotation movements of the equipment. The above are existing technologies and will not be described in detail here.

[0045] In its specific implementation, this invention is moved by a remote wirelessly controlled spiral propulsion device 5, and remote image feedback is provided by an infrared night vision device 11 and a 360° wireless camera 10. The drive motor 612, the first electric telescopic pole 901, the second electric telescopic pole 906, and the electric telescopic frame 4 are all controlled by remote control technology, which is existing technology and therefore not described in detail here. The lifebuoy 614 is launched in the rear end of the device. The rotating sleeve 801 and the main pole 701 are rotatably connected by a ball bearing 803, so that during the movement of this device, the tail end of the flag 804 is always opposite to the direction of movement of this device, so that the remote rescue personnel can clearly observe the direction of movement of this device, and after the device stops on the water surface, they can observe the wind direction on the water surface.

[0046] Specific Implementation Example 1: When it is necessary to throw the lifebuoy 614 to the victims, the lifebuoy ejection device 6 is pre-ejected into the pre-ejection state. The remote control drive motor 612 is used to move the sliding plate 602 and the sliding block 603 towards the front end. When the stop block 611 on the sliding block 603 contacts the locking block 610 at the lower end of the ejection switch plate 609, the sliding block 603 stops moving. At this time, the sliding plate 602 continues to move, so that there is relative movement between the sliding block 603 and the sliding plate 602, thereby compressing the spring 606 until the distance between the trapezoidal end 618 and the trapezoidal fixing block 604 is the smallest, and the lifebuoy ejection device 6 enters the pre-ejection state.

[0047] This device travels to the vicinity of the target water area via a spiral propulsion device 5, maintaining a distance from the victims to prevent waves caused by the movement from causing them to choke on water. With the rear end facing the victims, the remote-controlled drive motor 612 is activated to make the sliding plate 602 continue to move towards the front end. At this time, the trapezoidal end 618 connects with the trapezoidal fixing block 604, causing the ejection switch plate 609 to rotate upward around the pivot 608 and lift up, thereby disengaging the stop block 611 from the locking block 610. Then, under the elastic force of the spring 606, the sliding block 603 quickly ejects the lifebuoy 614, which can accurately eject the lifebuoy 614 in a certain direction, avoiding the situation where manual throwing is prone to excessive directional deviation and missing the best rescue time.

[0048] In specific embodiment 2, when a victim loses the ability to save themselves through the lifebuoy 614 due to excessive panic or choking on water, the spiral propulsion device 5 can be remotely controlled to travel to the target water area of ​​the victim, with the front end of the device facing the victim. The second electric telescopic pole 906 is extended to its maximum length via remote control, at which point the soft landing net 907 is fully opened. The first electric telescopic pole 901 is extended via remote control, causing the L-shaped connecting rod 902 to move downward. At this time, the second connecting rod 904 rotates, causing the electric telescopic pole seat 905 to rotate upward around the connecting shaft 903, thereby lifting the victim upward with the soft landing net 907. Compared with manual rescue, this reduces the rescue risk and increases the rescue success rate.

[0049] The present invention and its embodiments have been described above. This description is not restrictive, and the actual structure is not limited thereto. In summary, if those skilled in the art, inspired by this description, design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the scope of protection of this invention.
