Description

Technical Field

[0001] The present application relates to the technical field of catamaran hulls, and in particular to a double-hull connection structure for a high-speed aluminum alloy law enforcement boat. Background Art

[0002] In existing twin-hull designs, especially for specialized vessels like high-speed aluminum alloy law enforcement boats, the underwater hull structure is often fixed and lacks the necessary adjustment mechanisms. This fixed design is particularly limiting when operating in complex and changing environments.

[0003] Currently, most double-hull vessels feature fixed shapes and sizes for their underwater sections. This results in a fixed unit displacement frictional resistance during navigation, making it difficult to adapt to actual needs. In practical applications, law enforcement boats often need to navigate a variety of water environments, including narrow waterways, open lakes, and even rough seas. These diverse environments place extremely high demands on the boats' navigational performance.

[0004] However, due to the fixed underwater hull, existing double-hull vessels cannot effectively adjust their navigation attitude and resistance characteristics in different water conditions, thus affecting the vessel's navigation efficiency and stability. This limitation is particularly evident when sailing at high speeds or performing emergency missions, which can affect the law enforcement boat's maneuverability and response speed.

[0005] In view of the above problems, a double-piece connection structure of a high-speed aluminum alloy law enforcement boat is now designed. Utility Model Content

[0006] An embodiment of the present application provides a double-hull connection structure for a high-speed aluminum alloy law enforcement boat to solve the problem that some existing double-hull boats in the related art usually have an underwater hull part designed with a fixed shape and size and cannot be adaptively adjusted according to actual needs.

[0007] In a first aspect, a high-speed aluminum alloy law enforcement boat double-piece connection structure is provided, comprising:

[0008] Two sheets arranged opposite to each other, connected by a metal connecting bridge, and the outline of the sheet is shuttle-shaped;

[0009] Arc plates are attached to both sides of the sheet body, and an airbag is provided on the side of the sheet body arc plate close to the sheet body. There is a cavity inside the sheet body, and two groups of driving parts are arranged relatively inside the cavity. The driving parts are connected to the corresponding sheet body arc plates and are used to drive the sheet body arc plates away from or close to the sheet body.

[0010] In some embodiments, a partition is provided inside the cavity, and the partition is used to separate the cavity to form two independent storage chambers, and the airbag and the driving member are accommodated by the storage chambers.

[0011] In some embodiments, an air supply mechanism is embedded in the partition, and the air supply mechanism is used to evacuate or inflate the airbags on both sides.

[0012] In some embodiments, through holes are formed on both sides of the cavity, and the driving member extends outward through the through holes and is connected to the corresponding arc plate of the sheet body.

[0013] In some embodiments, the driving member includes a driving motor and a connecting plate connected to each other, the driving motor is arranged on the partition, and the connecting plate is connected to the sheet body arc plate.

[0014] In some embodiments, the two sheets and the metal connecting bridge are integrally cast.

[0015] This application provides a high-speed aluminum alloy law enforcement boat with a dual-plate connection structure. By dynamically adjusting the position of the plate arcs and the state of the airbags, the boat can optimize its underwater form according to different water conditions, thereby reducing resistance and improving navigation speed and stability. In emergency situations, such as when quickly crossing complex waters or conducting high-speed pursuits, the boat can adjust its underwater form to reduce resistance and improve maneuverability, thereby ensuring the safe completion of the mission.

[0016] This structure enables the law enforcement boat to better adapt to complex and changing water environments, and maintain optimal navigation performance whether it is narrow waterways, open lakes or rough seas. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0025] An embodiment of the present application provides a double-hull connection structure for a high-speed aluminum alloy law enforcement boat, which can solve the problem that some existing double-hull boats in the relevant technology usually adopt a fixed shape and size design and cannot be adaptively adjusted according to actual needs.

[0026] See also Figure 1-Figure 3 A high-speed aluminum alloy law enforcement boat double-sheet connection structure includes: two sheets 1 arranged opposite to each other, the two sheets 1 are connected by a metal connecting bridge 2, and the outline of the sheet 1 is shuttle-shaped; sheet arc plates 3 are attached to both sides of the sheet 1, and an airbag 4 is provided on the side of the sheet arc plate 3 close to the sheet 1. The sheet 1 has a cavity 5 inside, and two groups of driving members 6 are arranged opposite to each other inside the cavity 5. The driving members 6 are connected to the corresponding sheet arc plates 3 and are used to drive the sheet arc plates 3 away from or close to the sheet 1.

[0027] When the law enforcement boat needs to adapt to different water conditions, the driving member 6 located in the internal cavity 5 of the sheet body 1 will be activated. These driving members 6 can be electric push rods, hydraulic cylinders or other forms of driving devices, which are connected to the sheet body arc plate 3 through mechanical connections.

[0028] As the driving members 6 are activated, they push or pull the sheet arc plate 3, moving it away from or closer to the contact surface of the sheet 1. This movement can be an expansion movement away from the sheet 1 or a contraction movement close to the sheet 1.

[0029] The movement of the sheet body arc plate 3 not only changes its own position, but also affects the state of the air bag 4 connected thereto. When the sheet body arc plate 3 moves, the air bag 4 will be compressed or expanded, thereby further adjusting the resistance of the water flow to the law enforcement boat.

[0030] By adjusting the position of the arc plate 3 and the state of the airbag 4, the underwater shape of the law enforcement boat is optimized. This optimization enables the law enforcement boat to better adapt to different water flow conditions, reduce resistance, and improve navigation speed and stability.

[0031] By dynamically adjusting the position of the arc plate 3 and the state of the airbag 4, the law enforcement boat can optimize its underwater form according to different water conditions, thereby reducing resistance and improving navigation speed and stability. In emergency situations, such as when quickly crossing complex waters or conducting high-speed pursuit, the law enforcement boat can adjust its underwater form to reduce resistance and improve maneuverability, ensuring the safe completion of the mission.

[0032] This structure enables the law enforcement boat to better adapt to complex and changing water environments, and maintain optimal navigation performance whether it is narrow waterways, open lakes or rough seas.

[0033] Since key components such as the driving member 6 and the airbag 4 are located inside the sheet 1 or in easily accessible positions, the structure is relatively simple and convenient in terms of maintenance and care.

[0034] It should be noted that if Figure 1 As shown, the airbag 4 in this embodiment is located at the bottom of the driving member 6, that is, the airbag 4 is located on the side close to the underwater part of the sheet body 1.

[0035] Specifically, a partition 7 is provided inside the cavity 5 , and the partition 7 is used to separate the cavity 5 to form two independent storage chambers, and the airbag 4 and the driving member 6 are accommodated through the storage chambers.

[0036] The partition 7 separates the cavity 5 into two independent storage chambers. This separation not only ensures that the airbag 4 and the driving member 6 each have independent installation spaces, but also avoids mutual interference between them during operation.

[0037] In the compartmented storage chamber, the airbag 4 and driver 6 are separately installed. The airbag 4 is typically located near one side of the curved sheet 3, allowing it to compress or expand when the driver 6 pushes on the curved sheet 3, thereby adjusting the water flow resistance. The driver 6 is located opposite or to the side of the airbag 4 and is mechanically connected to the curved sheet 3, driving its movement.

[0038] The cavity 5 is divided into two independent storage chambers by the partition 7, so that the layout of the airbag 4 and the driving member 6 is more compact and orderly, thereby improving the utilization rate of the internal space of the law enforcement boat.

[0039] The separated storage chamber ensures the independence of the airbag 4 and the driving member 6 during operation, avoids mutual interference between them, and thus improves the stability and reliability of the entire system.

[0040] The independent storage chamber design makes the maintenance and care of the airbag 4 and the drive member 6 more convenient and quick. When necessary, the working status of these components can be easily accessed and checked, and necessary repairs or replacements can be made.

[0041] In one embodiment, an air supply mechanism 8 is embedded in the partition 7 , and the air supply mechanism 8 is used to evacuate or inflate the airbags 4 on both sides.

[0042] The partition 7 not only serves to separate the cavity 5, but also embeds an air supply mechanism 8 thereon. As a key component, the air supply mechanism 8 is responsible for supplying or extracting gas to the airbags 4 on both sides, thereby achieving the function of inflating and deflating the airbags 4.

[0043] The air supply mechanism 8 includes an air pump, air pipe, and valves. When the law enforcement boat needs to adjust the state of the airbag 4, the air supply mechanism 8 is activated to deliver or extract air to or from the airbag 4 through the air pipe. The valve controls the direction and volume of the gas flow, ensuring that the airbag 4 is inflated or deflated as expected.

[0044] As the air supply mechanism 8 is activated, the airbag 4 is inflated or deflated as needed. When inflated, the airbag 4 expands and clings to the sheet arc plate 3, increasing the contact area between the sheet arc plate 3 and the water flow, thereby increasing resistance. Conversely, when deflated, the airbag 4 contracts and moves away from the sheet arc plate 3, reducing the contact area and lowering resistance.

[0045] Furthermore, through holes are provided on both sides of the cavity 5 , and the driving member 6 extends outward through the through holes and is connected to the corresponding sheet arc plate 3 .

[0046] The through holes on both sides of the cavity 5 allow the driving member 6 to partially extend out of the cavity 5 and be directly connected to the sheet body arc plate 3. Usually achieved by bolts, pins or other mechanical connectors, ensuring that the driving member 6 can stably push or pull the sheet body arc plate 3.

[0047] In one embodiment, the driving member 6 includes a driving motor 61 and a connecting plate 62 that are connected to each other. The driving motor 61 is disposed on the partition 7 , and the connecting plate 62 is connected to the sheet arc plate 3 .

[0048] The drive member 6 is designed to include a combination of a drive motor 61 and a connecting plate 62. The drive motor 61 is mounted on the partition 7, while the connecting plate 62 is connected to the sheet body arc plate 3. This allows the drive motor 61 to effectively push or pull the sheet body arc plate 3 through the connecting plate 62, thereby achieving precise adjustment of the law enforcement boat's underwater configuration.

[0049] The drive motor 61 is a power source responsible for generating thrust or pull. It is usually mounted on the partition 7 to ensure its stability and reliability. When the control system sends a command to the drive motor 61, it starts and generates the required driving force.

[0050] The connecting plate 62 is the transmission component between the drive motor 61 and the sheet arc plate 3. One end of the connecting plate is connected to the output shaft of the drive motor 61, and the other end is connected to the sheet arc plate 3 via mechanical connectors such as bolts and pins. When the drive motor 61 generates driving force, this force is transmitted through the connecting plate 62 to the sheet arc plate 3, causing it to move along a predetermined trajectory.

[0051] As the connecting plate 62 rotates, the curved plate 3 moves away from or closer to the body 1 as needed. This movement not only changes the contact area and angle between the curved plate 3 and the water flow, but also affects the state of the airbag 4 connected to it. By precisely controlling the output force of the drive motor 61 and the transmission ratio of the connecting plate 62, the law enforcement boat can achieve fine-tuned underwater configuration.

[0052] In this embodiment, the two sheets 1 and the metal connecting bridge 2 are integrally cast.

[0053] The one-piece casting ensures a seamless connection between the sheet 1 and the metal connecting bridge 2, eliminating potential weaknesses such as welding or bolting. This integral structure can withstand greater stress and pressure, improving the overall structural strength of the law enforcement boat.

[0054] One-piece casting simplifies the manufacturing process, reduces assembly and commissioning time, improves production efficiency and reduces manufacturing costs.

[0055] The integrally cast structure makes the transition between the sheet body 1 and the metal connecting bridge 2 smoother, thereby reducing water flow resistance.

[0056] The one-piece cast structure has smooth lines and a seamless appearance, enhancing the overall aesthetics of the law enforcement boat.
