Description

Technical Field

[0001] This invention relates to the field of emergency rescue equipment technology, and in particular to a marine personnel safety rescue tool. Background Technology

[0002] Ships are vehicles that can navigate or anchor in waterways for transportation or operations. Ships have a wide range of applications, such as passenger ships, cargo ships, passenger-cargo ships, engineering vessels, and fishing boats. However, accidents can occur during ship voyages due to unforeseen circumstances, and not all passengers can swim. To improve their survival rate after falling into the water, lifesaving equipment is necessary. Currently, the main lifesaving equipment consists of life rings and lifeboats. However, current life rings and lifeboats can only be used in emergency situations, limiting their everyday use. Furthermore, they cannot provide power after falling into the water, forcing users to wait for rescue in a small area, resulting in limited safety and operability. Summary of the Invention

[0003] The technical problem that this invention aims to solve is that current lifesaving equipment can only be used in the event of an accident, and its daily use is relatively limited. At the same time, it cannot provide power after falling into the water, which means that users can only wait for rescue in a small area, and its safety and operability are relatively limited.

[0004] The technical solution adopted by the present invention to solve its technical problem is: a marine personnel safety and lifesaving tool, including a central shell, on both sides of the central shell are horizontally arranged cylindrical drive covers fixedly installed by a top mounting frame, an internal transmission cover is coaxially fixed inside the cylindrical drive cover by a fixed bracket, a plurality of inflatable airbags are installed inside the cylindrical drive cover, a central centrifugal pump and a compressed air tank with built-in compressed air are installed inside the central shell, and a lateral drive impeller assembly controlled by the central centrifugal pump is movably assembled inside the internal transmission cover.

[0005] The front end of the central housing has a front inlet that is connected to the front air inlet of the central centrifugal pump, and a conical filter screen is installed at the outer opening of the front inlet.

[0006] An internal circulation booster pump is installed inside the central housing, and the compressed air tank is connected to the air inlet and outlet of the inflatable airbag through the internal circulation booster pump.

[0007] The compressed air tank, the inflatable air bag, and the internal circulation booster pump are fixedly connected via an electronically controlled valve.

[0008] The built-in transmission cover has an internal transmission groove that protrudes into the cylindrical drive housing.

[0009] The lateral drive impeller assembly includes a lateral drive housing movably mounted inside the internal drive groove, centrifugal drive blades fixed on the lateral drive housing, and drive blades fixed on the inner arcuate surface of the lateral drive housing.

[0010] The guide pipe of the centrally mounted centrifugal pump is fixedly connected to the internal transmission groove through the inside of the top mounting frame.

[0011] An arc-shaped filter cover is installed inside the inlet on the outer side of the cylindrical drive housing.

[0012] A plurality of lateral control frames are welded and fixed on the outer surface of the cylindrical drive housing.

[0013] A control handle is installed on the side wall of the central housing.

[0014] The beneficial effects of this invention are: (1) A marine personnel safety rescue tool of the present invention has a top mounting frame that fixes horizontally arranged cylindrical drive covers on both sides of the central housing. Inside the cylindrical drive cover, there is a built-in transmission cover with a built-in lateral drive impeller assembly, which can provide sufficient power to drive on the water after falling into the water, thereby improving the initiative and operability of falling into the water rescue. (2) Multiple inflatable airbags are installed between the built-in transmission cover and the cylindrical drive cover. Compressed air tanks are used to provide air source, which can provide sufficient buoyancy on water and greatly improve protection. (3) The inflatable airbag can be inflated and deflated as needed, and can be reused, greatly reducing the cost of use. It can also be used as a submarine during idle time, making it more widely applicable. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0021] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0022] Figure 1 , Figure 2 and Figure 3 The illustrated marine personnel safety and lifesaving tool includes a central housing 1. Horizontally arranged cylindrical drive housings 3 are fixedly installed on both sides of the central housing 1 via a top mounting frame 2. An internal transmission housing 4 is coaxially fixed inside the cylindrical drive housing 3 via a fixed bracket. A plurality of inflatable airbags 5 are installed inside the cylindrical drive housing 3. A central centrifugal pump 6 and a compressed air tank 7 containing compressed air are installed inside the central housing 1. A lateral drive impeller assembly 8 controlled by the central centrifugal pump 6 is movably assembled inside the internal transmission housing 4.

[0023] To facilitate pre-liquid extraction, the front end of the central housing 1 is provided with a front inlet that is connected to the front air inlet of the central centrifugal pump 6, and a conical filter screen 101 is installed at the outer opening of the front inlet.

[0024] In order to control gas backflow, an internal circulation booster pump 9 is installed inside the central housing 1, and the compressed air tank 7 is connected to the air inlet and outlet of the inflatable air bag 5 through the internal circulation booster pump 9.

[0025] To facilitate adjustment, the compressed air tank 7, the inflatable air bag 5, and the internal circulation booster pump 9 are fixedly connected by an electronically controlled valve 10.

[0026] The main function of the internal circulation booster pump 9 is to draw the air inside the inflatable airbag 5 back into the compressed air tank 7, and the compressed air tank 7 does not need to go through the internal circulation booster pump 9 to inflate the inflatable airbag 5.

[0027] To facilitate internal installation, the built-in transmission cover 4 has an internal transmission groove that protrudes into the cylindrical drive housing 3.

[0028] To facilitate hydraulic drive, the lateral drive impeller assembly 8 includes a lateral drive housing 81 movably mounted inside the internal drive groove, centrifugal drive blades 82 fixed on the lateral drive housing 81, and drive blades 83 fixed on the inner arcuate surface of the lateral drive housing 81.

[0029] To control the drive, the guide pipe of the centrally located centrifugal pump 6 is fixedly connected to the internal transmission groove through the inside of the top mounting frame 2.

[0030] The centrally located centrifugal pump 6 draws water in through the front inlet, then guides it into the internal transmission groove through the guide pipe, and drives the centrifugal drive blades 82 to rotate the lateral transmission cover 81. The lateral transmission cover 81 then drives the drive blades 83 to rotate, thus driving the entire device to move on or inside the water.

[0031] To prevent external impurities from being drawn into the interior, an arc-shaped filter cover 31 is installed inside the inlet on the outer side of the cylindrical drive housing 3.

[0032] To facilitate grabbing by other people who have fallen into the water, or to suspend other auxiliary tools on the outside, a plurality of lateral control frames 32 are welded and fixed on the outer side of the cylindrical drive housing 3.

[0033] To facilitate control, a control handle 102 is installed on the side wall of the central housing 1.

[0034] A hand switch is installed on the control handle 102 to control the central centrifugal pump 6, the internal circulation booster pump 9 and the electric control valve 10 respectively. The central centrifugal pump 6 is used to provide driving force and adjust the position of the entire tool, while the internal circulation booster pump 9 and the electric control valve 10 work together to control the flow direction between the compressed air tank 7 and the inflation air bag 5.

[0035] When a ship accident occurs and personnel carrying equipment fall into the water or the equipment is thrown into the water, the user should immediately grasp the control handle 102 and press the inflation control switch: the electric control valve 10 will quickly open, the gas channel between the compressed air tank 7 and the inflation airbags 5 will be opened, and high-pressure compressed air will be quickly injected into multiple inflation airbags 5; the inflation airbags 5 will expand inside the cylindrical drive housing 3, gradually filling the gap between the cylindrical drive housing 3 and the internal transmission cover 4, generating sufficient buoyancy to make the equipment float quickly on the water surface and support the user's body to leave the water; during inflation, the user can control the opening of the electric control valve 10 and adjust the inflation speed through the adjustment switch on the control handle 102 to avoid the airbags from rupturing due to excessive inflation; when the airbags are fully inflated, the inflation switch should be released, and the electric control valve 10 will automatically close to maintain stable air pressure inside the airbags.

[0036] After buoyancy stabilizes, the user presses the start switch of the central centrifugal pump 6, and the equipment enters active driving mode: the central centrifugal pump 6 starts, drawing water from the surrounding water through the front inlet, and the conical filter screen 101 filters impurities in the water to prevent them from entering the pump body and causing malfunctions; the water flows through the guide pipe to the internal transmission groove of the built-in transmission cover 4, impacting the centrifugal drive blades 82 of the lateral drive impeller assembly 8 at high speed, driving the lateral transmission cover 81 to rotate, which in turn drives the blades 83 to rotate, generating a reverse thrust, and the equipment begins to travel on the water surface; the user adjusts the power of the central centrifugal pump 6 through the control handle 102: when the power is increased, the water volume increases, the water flow impact force is enhanced, and the travel speed is increased; when the power is decreased, the travel speed is slowed down; by adjusting the power difference of the central centrifugal pump 6 corresponding to the two cylindrical drive covers 3, the equipment can be turned, turned around, and other actions can be realized, flexibly adjusting the travel direction to approach other people who have fallen into the water or to drive to a safe area.

[0037] When other people in the water are spotted, the user can maneuver the equipment to the vicinity of the target person. The target person can grab the lateral control frame 32 on the outside of the cylindrical drive housing 3 and stay close to the equipment to avoid drowning. If more people need to be carried, a lifeline can be suspended through the lateral control frame 32 to connect multiple people in the water. If buoyancy needs to be adjusted during the journey, the inflation switch can be pressed again, and the electronic control valve 10 will open again to replenish the airbag 5 with gas and increase buoyancy. If shallow diving is required, the deflation switch can be pressed to start the internal circulation booster pump 9. The electronic control valve 10 will switch to gas recovery mode, drawing some of the gas in the airbag 5 back into the compressed air tank 7. The airbag volume will decrease, and the equipment will sink to shallow water. After the dive is completed, the equipment can be reversed to restore buoyancy.

[0038] After the rescue operation, the equipment is recovered to the ship or shore: the user presses the recovery switch, the internal circulation booster pump 9 starts, the electronic control valve 10 keeps the gas recovery channel open, the gas in the inflatable airbag 5 is gradually drawn back to the compressed air tank 7, and the airbag is gradually deflated; after the airbag is completely deflated, the electronic control valve 10 and the internal circulation booster pump 9 are closed, the impurities on the conical filter screen 101 and the arc-shaped filter cover 31 are cleaned, and the inflatable airbag 5 is checked for damage or leakage; compressed air is added to the compressed air tank 7 to ensure sufficient air supply for the next use; the operating status of the central centrifugal pump 6 and the internal circulation booster pump 9 is checked, and after confirming that there are no faults, the equipment is stored in the designated location for the next use.

[0039] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
