Description

Technical Field

[0001] This invention relates to the field of fire rescue, specifically to an underwater anchored drowning fire rescue device. Background Technology

[0002] Drowning rescue is an important part of the fire and rescue field. It refers to the emergency rescue operation in which firefighters use professional equipment and technology to search for and rescue people drowning in water, provide timely floating support for drowning victims, guide them out of dangerous waters, and assist with subsequent medical treatment. Its core objective is to maximize the safety of drowning victims and reduce the casualty rate of drowning accidents. It is suitable for sudden drowning scenarios in various water bodies such as rivers and lakes. Underwater anchored drowning rescue devices are commonly used professional equipment in drowning rescue. They are mainly composed of anchoring structures, floating components, and transmission components. They can be fixed to a designated underwater rescue area through anchoring components and use floating components to provide temporary floating support for drowning victims. At the same time, they can be used in conjunction with relevant auxiliary structures to realize rescue operations. They can be flexibly deployed by drones or remotely controlled unmanned boats and can stay in the designated water area for a long time to provide continuous support for drowning rescue.

[0003] However, in the existing technology, the floating structure of underwater anchored drowning fire rescue devices is mostly fixed, making it difficult to flexibly adjust the buoyancy and adapt to the rescue needs of different water depths and current environments. In scenarios with deep water or strong currents, the buoyancy of the anchoring base is often insufficient, resulting in poor floating stability of the device, easy sinking or shaking, and interference with the smooth progress of rescue operations. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an underwater anchored drowning fire rescue device, which solves the problem that in existing underwater anchored drowning fire rescue devices, the floating structure is mostly a fixed design.

[0008] Preferably, the expansion assembly further includes a bidirectional threaded rod, the outer wall of which is rotatably connected to the inner wall of the limiting block, the outer wall of which is threadedly connected to the inner wall of the first slider, and a first disk rotatably connected to the outer wall of the bidirectional threaded rod. A motor is fixedly connected to the top of the first disk, and the output end of the motor is rotatably connected to the inner wall of the first disk and fixedly connected to the top of the motor.

[0009] Preferably, the warning component includes a second slider, the inner wall of which is threadedly connected to the outer wall of a bidirectional threaded rod, a support rod is fixedly connected to the inner wall of the second slider, a second disk is fixedly connected to the upper surface of the support rod, and a safety warning sign ball is fixedly connected to the top of the second disk.

[0010] Preferably, the floating assembly includes a floating plate, the upper surface of which is fixedly connected to the lower surface of a limiting rod, the lower surface of which is slidably connected to the top of an anchoring base, and a limiting slider fixedly connected to the lower surface of the floating plate, the outer wall of which is slidably connected to the inner wall of the floating plate.

[0011] Preferably, the floating assembly further includes a floating ring, the outer wall of which is fixedly connected to the outer wall of the floating plate, an L-shaped slider is fixedly connected to the lower surface of the floating plate, a limiting plate is fixedly connected to the outer wall of the L-shaped slider, the outer wall of the limiting plate is abutting against the outer wall of the main anchor, and the outer wall of the limiting plate is slidably connected to the bottom end of the anchoring base.

[0012] Preferably, the opening and closing assembly includes a first rack, the lower surface of which is fixedly connected to the upper surface of the L-shaped slider, and the outer wall of the first rack is slidably connected to the inner wall of the anchoring base.

[0013] Preferably, the opening and closing assembly further includes a first gear, the tooth end of the first gear meshing with the tooth end of the first rack, a rotating column fixedly connected to the inner wall of the first gear, and the outer wall of the rotating column rotatably connected to the inner wall of the anchoring base.

[0014] Preferably, the opening and closing assembly further includes a second gear, the inner wall of which is fixedly connected to the outer wall of the second gear, the tooth end of the second gear is meshed with a second rack, the outer wall of the second rack is slidably connected to the inner wall of the anchoring base, and an opening and closing plate is fixedly connected to the outer wall of the second rack, the outer wall of the opening and closing plate being slidably connected to the inner wall of the anchoring base.

[0015] Working principle: When it is necessary to increase the buoyancy of the anchoring base, the motor is started. The rotation of the motor's output end drives the bidirectional threaded rod to rotate, causing it to rotate on the inner wall of the first disc and the limiting block. This rotation of the bidirectional threaded rod then moves the first slider, which in turn moves the second fixed block. The movement of the second fixed block then drives the third transmission rod to rotate, causing it to slide on the inner wall of the second transmission rod. This rotation of the third transmission rod then moves the limiting rod. During this process, the movement of the limiting rod causes the float to move, sliding onto the top of the anchoring base. This movement of the float causes the float ring to move, which in turn causes the limiting slider to move, sliding against the inner wall of the anchoring base. This increases the buoyancy of the anchoring base, improving its stability and reducing the risk of sinking due to insufficient buoyancy. It adapts to rescue needs in different water depths and current environments, providing a more stable floating support platform for drowning victims and reducing the impact of water currents.

[0016] When it is necessary to increase the warning height of the safety warning ball, the motor is started. The rotation of the motor's output end drives the bidirectional threaded rod to rotate, causing the bidirectional threaded rod to rotate on the inner wall of the first disc and the limiting block. In turn, the rotation of the bidirectional threaded rod drives the second slider to move. During this process, the movement of the second slider drives the support rod to move, which in turn drives the second disc to move. This movement of the second disc causes the safety warning ball to move upward, thereby increasing the warning height of the safety warning ball. This improves the visibility range of the safety warning ball, making it easier for rescuers, passing ships, and people in the surrounding area to spot the rescue area. It is adaptable to different rescue scenarios. When the rescue area is obstructed by obstacles, the water is deep, or the visibility is poor, the warning height can be increased to avoid obstruction and ensure that the warning effect is not affected.

[0017] When it is necessary to release the main anchor's limit, the movement of the floating plate drives the L-shaped slider to move, which in turn moves the limit plate. When the limit plate slides out of the main anchor, the main anchor's limit is released, thus achieving the effect of releasing the main anchor's limit. This facilitates flexible control of the main anchor's fixing and loosening, allows for rapid retrieval of the main anchor after rescue operations are completed, reduces the time and difficulty of main anchor retrieval, and improves the overall retrieval efficiency of the device.

[0018] When the secondary anchor is needed, the movement of the limiting plate moves the first rack, causing it to rotate. This rotation of the first rack drives the first gear, which in turn rotates the rotating column, causing it to rotate against the inner wall of the anchoring base. During this process, the rotating column rotates the second gear, which in turn moves the second rack. This movement of the second rack then moves the opening and closing plate, causing the first rack, second rack, and opening and closing plate to slide against the inner wall of the anchoring base. When the opening and closing plate slides out of the anchoring base, the secondary anchor can be used. This achieves the desired effect of using the secondary anchor, allowing for flexible control of its activation, reducing operational difficulty for personnel, and facilitating timely activation based on underwater anchoring needs. This is especially beneficial in complex underwater geological conditions, strong currents, and when the primary anchor alone is ineffective; activating the secondary anchor creates dual anchoring, reducing the risk of device displacement.

[0019] This invention provides an underwater anchored drowning fire rescue device. It has the following beneficial effects: 1. This invention uses a starting motor to drive a bidirectional threaded rod to rotate on the inner wall of the first disc and the limiting block, thereby moving the floating plate. The floating plate drives the floating ring and the limiting slider to slide along the anchoring base to increase buoyancy. This can effectively improve the stability of the anchoring base, reduce the risk of sinking due to insufficient buoyancy, adapt to the rescue needs of different water depths and current environments, provide a more stable floating support platform for drowning victims, and at the same time reduce the impact of water flow on the overall device, ensuring the smooth conduct of rescue operations.

[0020] 2. This invention uses a second slider to drive a support rod and a second disc in a coordinated manner, which moves the safety warning sign ball upward to increase the warning height. This effectively improves the visibility range of the safety warning sign ball, making it easier for rescuers, passing vessels, and nearby personnel to quickly locate the rescue area. It is adaptable to different rescue scenarios. When the rescue area is obstructed by obstacles, the water is deep, or the visibility is poor, the increased warning height can avoid obstruction and ensure that the warning effect is not affected. This creates a safe surrounding environment for rescue operations and improves the pertinence and safety of the warning at the rescue site.

[0021] 3. This invention uses the movement of the limiting plate to drive the opening and closing plate to slide along the inner wall of the anchoring base. When the opening and closing plate disengages from the anchoring base, the secondary anchoring is activated. The timing of the activation of the secondary anchoring can be flexibly controlled, reducing the difficulty of operation for the staff and facilitating the timely activation of the secondary anchoring according to underwater anchoring needs. Especially when the underwater geology is complex, the water flow is strong, and the main anchoring alone is not effective, the activation of the secondary anchoring can form a double anchoring, reducing the risk of device displacement and improving the anchoring stability of the device in complex underwater environments.
