Description

Technical Field

[0001] The present invention belongs to the technical field of inflatable boats, and specifically relates to an emergency rescue boat. Background Art

[0002] An inflatable boat is an inflatable vessel. Compared with traditional boats, inflatable boats can adapt to various water areas and are widely used in water-based leisure, entertainment, fishing, fishing and other water operations. They have the advantages of being lightweight and multifunctional. Especially in emergency rescue, they have significant advantages and convenience.

[0003] The hull of an inflatable boat is generally made of an inflatable buoyancy tire made of elastic material. At the same time, the inflatable buoyancy tire is divided into multiple independent air chambers, and the partition is set with high airtightness. When an individual air chamber is damaged, the other parts still maintain sufficient buoyancy. The power unit mainly uses an outboard motor installed at the stern of the boat. When the outboard motor is in use, the propeller is driven to rotate by the motor, and the propeller forms a push in the water to push the inflatable boat forward.

[0004] Emergency rescue boats are usually used in extremely complex water environments, such as floods, heavy rains, waterlogging and other environments. When such natural disasters occur, there are usually difficulties in the impassable roads, making it difficult to transport conventional rigid rescue boats to the disaster area. At the same time, there will be a large number of floating objects in the water, which will pose a serious threat to the operation of the outboard motor, and even cause the working load of the outboard motor to exceed the standard, resulting in damage to the outboard motor and seriously affecting emergency rescue work.

[0005] Therefore, the present invention provides an emergency rescue boat. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0029] Embodiment 1

[0030] As Figures 1 to 4As shown in the figure, an emergency rescue boat according to an embodiment of the present invention includes a hull 1, a wire-drawing bottom plate 2, a gas cylinder 3, a fairing 4, and a fan propeller 5. The hull 1 is formed by connecting a plurality of capsules in series at the head and tail. Adjacent capsules are connected through a pipeline, and a valve is provided in the middle of the pipeline. A wire-drawing bottom plate 2 is fixedly connected to the middle of the hull 1. A gas cylinder 3 is fixedly connected to the tail of the hull 1. The air outlet end of the gas cylinder 3 is communicated with the hull 1. A fairing 4 is pin-connected to the top surface of the wire-drawing bottom plate 2 near the tail of the hull 1. A fan propeller 5 is fixedly connected to the middle of the fairing 4. In this embodiment, the wire-drawing bottom plate 2 is a flexible inflatable material inside. It can be deformed and folded when not inflated, and has a certain stiffness and bearing capacity after being inflated inside. An air guide opening is provided in the middle of the wire-drawing bottom plate 2. Transverse plate beams and longitudinal beams are pre-installed inside the wire-drawing bottom plate 2. The wire-drawing bottom plate 2 is connected to the capsules of the hull 1 around its perimeter, and air valves and gas cylinders are provided at the top for inflation and deflation. Tether holes for fixing the apron 9 are provided on the side of the bottom of the wire-drawing bottom plate 2. When not inflated, both the hull 1 and the wire-drawing bottom plate 2 are in a compressed and folded state, which is convenient for the staff to pack and transport them to the flood disaster area for use, improving the convenience and passability of transportation. At the same time, the staff can use a parachute pack for airdrop, further expanding the applicable range of the emergency rescue boat. When in use, the gas cylinder 3 is used to inflate the hull 1 and the wire-drawing bottom plate 2, causing the hull 1 to expand and the wire-drawing bottom plate 2 to unfold and harden, forming the hull of the rescue boat. The fairing 4 is fixedly installed on the wire-drawing bottom plate 2 using a fixing pin to complete the assembly of the rescue boat. The fan propeller 5 provides backward wind force to push the rescue boat to travel on the water surface, and floating objects in the water cannot hinder the power of the rescue boat, improving the safety of the rescue boat's operation. Moreover, the hull 1 formed by connecting a plurality of capsules in series ensures that even if a certain capsule is punctured by a floating object in the water, the hull 1 still has buoyancy, reducing the probability of the rescue boat sinking.

[0031] As Figures 1 to 4 shown, a flexible air guide cover 6 is fixedly connected to the bottom of the side of the fairing 4 close to the tail of the hull 1. The bottom of the flexible air guide cover 6 is fixedly connected to the wire-drawing bottom plate 2, and the inner ring of the flexible air guide cover 6 penetrates through the wire-drawing bottom plate 2. During operation, the fan propeller 5 provides backward wind force to push the rescue boat to travel on the water surface. At the same time, part of the airflow is guided by the flexible air guide cover 6 to the bottom of the wire-drawing bottom plate 2, lifting the rescue boat upward, reducing the contact between the rescue boat and the water surface, not only reducing the frictional resistance between the rescue boat and the water surface, but also reducing the damage to the rescue boat caused by floating objects in the water.

[0032] As Figures 1 to 4 shown, a bracket 7 is fixedly connected to the side of the fairing 4 close to the tail of the hull 1. A plurality of rudder surfaces 8 are rotatably installed in the middle of the bracket 7, and the plurality of rudder surfaces 8 are connected in series through connecting rods. During operation, the staff controls the movement of the connecting rods through the steering wheel, causing the plurality of rudder surfaces 8 to rotate synchronously, thereby adjusting the wind direction of the fan propeller 5 and then controlling the direction of the rescue boat.

[0033] As Figures 1 to 3 shown, an apron 9 is fixedly connected to the bottom of the hull 1; the apron 9 forms an air chamber around the bottom of the hull 1, and the wind generated by the fan propeller 5 blows into the air chamber at the bottom of the rescue boat through the flexible air duct 6, so that the air chamber is always filled with high-pressure gas, providing an upward lifting force for the rescue boat, thereby generating an air cushion at the bottom of the boat to achieve the effect of the rescue boat taking off into the air; at the same time, the provided apron 9 provides additional buoyancy for the hull 1, improving the carrying capacity of the rescue boat.

[0034] As Figures 1 to 3 shown, movable tail vertebrae 10 are fixedly connected to both ends of the stern of the hull 1, and the movable tail vertebrae 10 are connected to adjacent capsules through pipes; the movable tail vertebrae 10 provided on both sides of the hull 1 enhance the balance performance and stability performance of the rescue boat, provide support when the rescue boat turns at high speed, and effectively reduce the probability of the rescue boat capsizing.

[0035] As Figures 1 to 3 shown, a clamp 11 is installed on the outer ring of the movable tail vertebra 10, and a hydrodynamic thruster 27 is fixedly connected to the bottom of the clamp 11; the hydrodynamic thruster 27 in this embodiment is a small electric-driven hydrodynamic thruster, which is powered by the hybrid oil-electric power device carried on the hovercraft and is fixed on the fixed base of the movable tail vertebra 10 by using the clamp 11; when the rescue boat moves forward, the hydrodynamic thrusters 27 on both sides are started simultaneously to provide auxiliary forward power for the rescue boat, and at the same time, the probability of the rescue boat capsizing is reduced; when the rescue boat moves backward, the hydrodynamic thrusters 27 on both sides are started in the reverse direction simultaneously to push the rescue boat backward; when the rescue boat turns around or turns in a narrow area, only one side of the hydrodynamic thruster 27 needs to be turned on to push the rescue boat to turn around and turn; thereby improving the applicable range of the rescue boat and improving the rescue ability of the rescue boat.

[0036] As Figures 1 to 3 shown, a plurality of handles 12 are evenly and fixedly connected to the outer side of the top of the hull 1, and a plurality of hanging rings 13 are evenly and fixedly connected to the inner side of the top of the hull 1; through the provided handles 12, it is convenient for passengers to grip and improves safety; through the provided hanging rings 13, it is convenient for the staff to hoist and carry materials.

[0037] Embodiment 2

[0038] As Figures 5 to 6As shown in the figure, compared with the first comparative example, another implementation of the present invention is as follows: A mounting seat 14 is fixedly connected to the middle of the wire drawing bottom plate 2. A baffle 15 is hinged to the side of the mounting seat 14 away from the flow guide cover 4. A torsion spring is sleeved outside the rotating shaft of the baffle 15. A fixing seat 16 is fixedly connected to the side of the wire drawing bottom plate 2 away from the flow guide cover 4. A fixing rod 17 is fixedly connected to the top of the baffle 15. The fixing seat 16 is fixedly connected to the fixing rod 17 through a pin; after the rescue boat rescues the disaster victims, when the disaster victims take the rescue boat, while the fan propeller 5 generates a backward wind force, a relatively large wind force will be formed on the rescue boat, and the disaster victims are in this area, making the disaster victims feel uncomfortable; Therefore, this embodiment provides a solution: When it is necessary to pick up the disaster victims, pull out the pin between the fixing rod 17 and the fixing seat 16, and the baffle 15 rotates under the action of the torsion spring, so that the baffle 15 rotates to a vertical state, separating the fan propeller 5 from the middle of the rescue boat, so that a region with a relatively small wind force is formed in the middle of the rescue boat, thereby improving the comfort of the disaster victims when taking the boat.

[0039] As Figures 5 to 6 shown, a plurality of bases 18 are uniformly fixedly connected to the middle of the side of the wire drawing bottom plate 2 away from the flow guide cover 4. Winches 19 are rotatably installed outside the vertical rods on both sides of the base 18. A torsion spring is arranged inside the winch 19. A pull rope 20 is uniformly wound around the outer circle of the winch 19. One end of the pull rope 20 away from the base 18 is fixedly connected to a hook 21; during operation, pull the pull rope 20, pull out the pull rope 20 from the outer circle of the winch 19, so that the winch 19 rotates, and hook the hook 21 to the hanging rings 13 on both sides of the hull 1 to form a net in the middle of the rescue boat, which is not only convenient for the disaster victims to grasp, but also convenient for tying various materials, improving the overall safety.

[0040] As Figures 5 to 6 shown, a sliding ring 22 is sleeved outside the pull rope 20. Bolts 23 are threadedly installed on both sides of the sliding ring 22. A screw rod 24 is fixedly connected to the top of the sliding ring 22. A nut 25 is threadedly installed on the top of the screw rod 24. A pressing piece 26 is slidably installed outside the top of the screw rod 24. The outer circle of the screw rod 24 is slidably matched with the top groove of the base 18; after the hook 21 is hooked to the hanging rings 13 on both sides of the hull 1, slide the sliding ring 22 so that the sliding ring 22 moves along the pull rope 20 to the base 18, so that the screw rod 24 is stuck in the groove of the base 18, and use the nut 25 to press the pressing piece 26 against the top of the base 18 to fix and lock the sliding ring 22, and then rotate the bolts 23 on both sides to lock the pull rope 20 and the sliding ring 22, thereby locking the extended length of the pull rope 20, and then improving the safety of the pull rope 20 during use.

[0041] During operation: When not inflated, both the hull 1 and the wire drawing bottom plate 2 are in a compressed and folded state, which is convenient for the staff to pack and transport them to the flood disaster area for use, improving the convenience and passability of transportation. At the same time, the staff can use the parachute pack for airdropping, further expanding the application range of the emergency rescue boat.

[0042] When in use, the gas cylinder 3 is used to inflate the hull 1 and the wire drawing bottom plate 2, causing the hull 1 to expand and the wire drawing bottom plate 2 to unfold and harden, forming the hull of the rescue boat. The fairing 4 is fixedly installed on the wire drawing bottom plate 2 using fixing pins to complete the assembly of the rescue boat. The fan propeller 5 provides backward wind force. The staff controls the movement of the connecting rod through the steering wheel, causing multiple rudder surfaces 8 to rotate synchronously, thereby adjusting the wind direction of the fan propeller 5 and then controlling the direction of the rescue boat, and pushing the rescue boat to travel on the water surface. Floating objects in the water cannot impede the power of the rescue boat, improving the safety of the rescue boat's operation. At the same time, the hydrokinetic thrusters 27 on both sides are started simultaneously to provide auxiliary forward power for the rescue boat.

[0043] At the same time, the apron 9 forms an air chamber around the bottom of the hull 1. The fan propeller 5 provides backward wind force to push the rescue boat to travel on the water surface. Part of the airflow is introduced into the bottom of the wire drawing bottom plate 2 by the flexible air deflector 6, blowing air into the air chamber at the bottom of the rescue boat, so that the air chamber is always filled with high-pressure gas, providing an upward lift force for the rescue boat, thus generating an air cushion at the bottom of the boat, achieving the effect of the rescue boat taking off, reducing the contact between the rescue boat and the water surface, not only reducing the frictional resistance between the rescue boat and the water surface, but also reducing the damage of floating objects in the water to the rescue boat. At the same time, the apron 9 provided provides additional buoyancy for the hull 1, improving the carrying capacity of the rescue boat. Floating objects in the water cannot impede the power of the rescue boat, improving the safety of the rescue boat's operation. Moreover, the hull 1 formed by connecting multiple capsules in series ensures that even if a certain capsule is punctured by a floating object in the water, the hull 1 still has buoyancy, reducing the probability of the rescue boat sinking.

[0044] When it is necessary to pick up the disaster victims, after the rescue boat rescues the disaster victims and the disaster victims board the rescue boat, when the fan propeller 5 generates a backward wind force, a relatively large wind force will be formed on the rescue boat, and the disaster victims will be in this area, making the disaster victims feel uncomfortable; at this time, pull out the pin between the fixing rod 17 and the fixing seat 16, and the baffle 15 rotates under the action of the torsion spring, so that the baffle 15 rotates into a vertical state, separating the fan propeller 5 from the middle part of the rescue boat, making the middle part of the rescue boat form an area with a relatively small wind force, and improving the comfort of the disaster victims when boarding; pull the pull rope 20, pull the pull rope 20 out from the outer ring of the winch 19, so that the winch 19 rotates, and hook the hook 21 to the hanging rings 13 on both sides of the hull 1. Slide the sliding ring 22 so that the sliding ring 22 moves along the pull rope 20 to the base 18, so that the screw rod 24 is stuck in the groove of the base 18, and use the nut 25 to press the pressing piece 26 tightly on the top of the base 18 to fix and lock the sliding ring 22. Then rotate the bolts 23 on both sides to lock the pull rope 20 and the sliding ring 22, forming a net in the middle of the rescue boat, which is not only convenient for the disaster victims to hold, but also convenient for tying various materials, improving the overall safety;

[0045] When it is necessary to turn, according to the range conditions of the water area, when the water surface of the water area is relatively wide, the rudder surface 8 can be directly adjusted to turn. When the water area is relatively narrow and it is impossible to directly turn around; when the rescue boat retreats, the two hydrodynamic thrusters 27 start in the reverse direction at the same time to push the rescue boat to retreat; when the rescue boat turns around or turns in a narrow area, when turning to one side, turn off the hydrodynamic thruster 27 on that side, or reverse the hydrodynamic thruster 27 on that side, and turn on the hydrodynamic thruster 27 on the other side to push the rescue boat to turn around and turn; thereby improving the applicable range of the rescue boat and the rescue ability of the rescue boat.

[0046] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
