A composite air supply component, a composite airbag component, an intelligent control component and a mechanical transmission component are arranged in the shell. The intelligent control component is used to predict the impact energy and the impact angle of the collision object, and send an inflation instruction to the composite air supply component to inflate the large airbag to a suitable air pressure and the small airbag to a rated air pressure, and send an angle adjustment instruction to the mechanical transmission component to adjust the collision angle of the small airbag. The large airbag cooperates with the small airbag to fully absorb the collision force acting vertically on the surface of the hull, and then the collision force parallel to the surface of the hull is transferred through the special angle combination of the small airbag.

It is different from a traditional ship anti-collision device with a fixed protection area, a constant protection angle and limited protection capability.

Description

Technical Field

[0001] The invention belongs to the technical field of ships, and in particular relates to an airbag-based modular intelligent anti-collision device for ships. Background Art

[0002] At present, with the continuous development and utilization of marine resources, fisheries, transportation, tourism, and resource mining have all made great progress. As an important transportation carrier, the shipbuilding industry is also booming, among which ships with high economic value, such as luxury yachts, high-specification fishing boats, and special scientific research ships are constantly emerging. However, due to various factors such as severe sea conditions and human negligence, collision accidents of ships with high economic value often occur in offshore, inland rivers, ports and other areas. Due to its own economic value, if an accident occurs, it will not only cause huge economic and property losses, but also cause unimaginable damage to the safety of life and property of personnel. my country's ships with high economic value are constantly developing, but the protective equipment for ships still needs to be continuously developed. Most of the existing external devices for ship collision prevention are still waste tires or rubber balls exposed on the outside. Waste tires not only affect the appearance, but also have limited protective capabilities. Rubber balls are generally used when berthing or mooring, and cannot appear in time for emergencies; and because they are suspended on the side and float in the water, they cannot accurately and continuously protect a specific area of ​​the ship. In addition, the existing marine inflatable protection equipment mostly uses a single inflatable closed bladder, which only absorbs energy through compression deformation when dealing with collision forces. For collisions at a certain angle, it may even slip or lose its position. In summary, high-value ships are in urgent need of designing an intelligent airbag protection device that can provide protection in a limited volume. It is installed in various important structural areas and can work independently or in groups for joint protection. In the case of a collision hazard, it can quickly calculate the impact energy to be suffered, as well as the collision angle and contact surface shape of the protection area, and provide effective protection through intelligent control.

[0006] The airbags are made of a watertight and airtight material, and can withstand sufficient external impact without damage or leakage. Since the small airbags are in the shape of a teardrop, with one end larger than the other, and the air inlet of the small airbag is located close to the side of the hull, the internal small airbag can be rotated and adjusted to the optimal collision angle through a mechanical transmission assembly to better disperse the collision energy. The force component parallel to the hull surface is better separated into a horizontal direction, so that part of the energy that destroys the hull structure can be transferred and disappear in the form of surface sliding. The use of two small airbags ensures that at a given collision angle, the energy can be transferred in a balanced and stable manner, avoiding the situation where a single small airbag is damaged due to the small bottom force area and unstable angle during operation.

[0007] Preferably, the composite gas supply assembly is located above one side of the shell; the composite gas supply assembly includes a high-pressure steel cylinder, a gas transmission channel A, a gas transmission channel B, a gas generator, and an electric airtight valve; the gas generator and the electric airtight valve are electrically connected to the intelligent control assembly; the high-pressure steel cylinder is connected to the electric airtight valve; the electric airtight valve is connected to the large air bag through the gas transmission channel A; the gas generator is connected to the small air bag through the gas transmission channel B.

After calculating that there is a collision risk, the central processing unit calculates the energy impact that the protected area is about to suffer, as well as the contact surface shape and collision angle of the collision object that the area is about to contact; the predicted impact energy is converted into the appropriate air pressure of the large air bag, and the collision contact surface shape and collision angle are converted into the collision angle of the small air bag.

[0011] The navigation direction, relative position, height difference, draft, relative speed, surface shape of the collision object and other information are obtained and processed, and the contact position between the protection area and the collision object, that is, the curvature of the collision object contact surface, is predicted. And the energy value range brought to the ship by the collision object is predicted and calculated. The intelligent control component converts this information into the optimal internal pressure of the external airbag and the optimal collision angle of the internal airbag. The electric valve in the composite inflation component is opened, and the high-pressure gas in the high-pressure cylinder quickly inflates the external spherical airbag. When the internal pressure reaches the optimal pressure, the electric valve is closed. At the same time, the gas generator also ignites and inflates the internal water drop-shaped airbag.

Since transmission rack A meshes with gear B, it drives gear B to rotate. At the same time, gear B meshes with transmission rack B, causing transmission rack B to move right. Since gears C and D are meshed with transmission rack B, small air outlets A and B are deflected, thereby causing the small airbag to rotate. Similarly, when the motor reverses, the small airbag rotates in the opposite direction.

Before each shell module is installed in a cluster, according to the needs of the ship's side protection area, the length of the retractable connecting rod 25 is adjusted first, and then each shell module is connected by the retractable connecting rod.

[0037] The module includes a shell 24, the outer surface of which may be covered with a skin to provide a certain degree of concealment; an intelligent control component is arranged on the lower left side of the shell 24, a composite air supply component is arranged on the upper left side of the shell 24, and a mechanical transmission component is arranged on the right side of the shell 24. The composite airbag component occupies the largest space inside the shell 24 and is arranged on the lower right side of the shell 24; the composite airbag component includes a large airbag 10 and a small airbag 11; the composite air supply component supplies air to the composite airbag component; the composite airbag component is used to resist external collision of the hull and protect the hull structure; the mechanical transmission component is used to adjust the collision angle of the small airbag 11; the intelligent control component is used to predict the impact energy and collision angle of the collision object, and send an inflation instruction to the composite air supply component to inflate the large airbag 10 to a suitable air pressure and the small airbag 11 to a rated air pressure, and send an angle adjustment instruction to the mechanical transmission component to adjust the angle of the small airbag 11.

[0038] The intelligent control component includes an image collector, an infrared rangefinder 1, a central processing unit 2 and a plurality of wires; the wires are electrically connected to the electric airtight valve 22, the gas generator 4 and the small motor 17 in the mechanical transmission component in the composite air supply component; the image collector is used to collect and identify potential collision objects in the surrounding area and the sea condition information near the waters where the ship is located; the infrared rangefinder 1 cooperates with the image acquisition sensor to send the environmental information and obstacle information to the central processing unit 2, and the central processing unit 2 preliminarily calculates whether there is a collision risk. After calculating that there is a collision risk, the central processing unit 2 calculates the energy impact that the protected area is about to suffer, as well as the contact surface shape and collision angle of the collision object that the area is about to contact; the predicted impact energy is converted into the appropriate air pressure of the large air bag 10, and the collision contact surface shape and collision angle are converted into the appropriate collision angle of the small air bag 11.

[0039] The composite gas supply assembly includes a high-pressure steel cylinder 3, a gas transmission channel A 15a, a gas transmission channel B 15b, a gas generator 4, and an electric airtight valve 22; the gas generator 4 and the electric airtight valve 22 are electrically connected to the intelligent control assembly; two steel cylinder brackets are arranged in the housing 24, and a gasket is installed in each steel cylinder bracket before the high-pressure steel cylinder 3 is installed, and the gasket can reduce the shaking of the high-pressure steel cylinder 3 and improve the safety of gas storage in the high-pressure steel cylinder 3; the electric airtight valve 22 is provided with two airtight interfaces, one of which is provided with a Y-shaped three-way pipe A, and the other airtight interface is connected to the gas transmission channel A 15a, and the gas transmission channel A 15a is connected to the large air bag 10 through the large air outlet 5; the electric airtight valve 22 is connected to the two high-pressure steel cylinders 3 through the Y-shaped three-way pipe A; the gas generator 4 is provided with a Y-shaped three-way pipe B, and the gas generator 4 is connected to the small air bag 11 through the Y-shaped three-way pipe B. The channel connection in the device is provided with a rubber airtight gasket for sealing. Two air supply modes are used.

The high-pressure cylinder 3 provides the most suitable air pressure for the large airbag 10, and the gas generator 4 provides the rated air pressure for the small airbag 11 to fully absorb the energy generated by the collision. Since the external large airbag is mainly used for energy release and to cope with various levels of impact energy, different internal pressures have different protective effects. Therefore, it is necessary to control the internal pressure of the external large airbag to cope with different levels of impact energy. For the small airbag without a vent hole, it only needs to be filled to the rated pressure.

[0040] A storage compartment 14 is provided in the housing. When the airbag is not deployed, it is folded and placed in the storage compartment, occupying little space. Fig.10 The air bag 10 shown is spherical, and the surface of the air bag 10 is provided with annularly arranged air leakage holes 12; the air leakage holes 12 are used to fully buffer and release energy; the air bag 10 not only absorbs energy by compressing the volume, but also releases a large amount of energy through the air leakage holes; a circular ring support frame 27 is arranged near the air outlet inside the air bag 10 to open the air bag near the bottom, and two small air bags 11 are symmetrically arranged inside the air bag; at the same time, wrapping strips are arranged around the outer surface of the air bag, and a light rod 16 is arranged inside the wrapping strip, the two ends of the vertical light rod are fixedly connected to the shell, and the rest of the place has a gap, and the middle part of the horizontal light rod has two points fixedly connected to the shell, and the rest of the place has a gap with the shell; the light rod is a lightweight aluminum alloy rod; when the air bag is unfolded to receive a collision and is used to resist the impact, the light rod can maintain the stability of the air bag to ensure that it will not deviate or shift.

The use of two small airbags ensures that the balance and stability can be achieved during sliding, and avoids the damage of the small airbag caused by the small force area at the bottom of the small airbag and the unstable work.

The two ends of the retractable connecting rod 25 are respectively fixed to the connecting hole 13, and finally fixed to the side of the ship by a strong magnetic strip 8;

[0045] The intelligent control component collects and processes the navigation direction, relative position, height difference, draft, relative speed, surface shape of the collision object, etc. acquired by the image acquisition sensor and infrared rangefinder 1 and other sensors, and predicts the contact position between the protection area and the collision object, that is, the curvature of the collision object contact surface; and predicts and calculates the energy value range brought by the collision object to the ship; the intelligent control component converts this information into the optimal internal pressure of the large airbag 10 and the optimal collision angle of the internal small airbag 11;

[0046] The intelligent control component sends the gas supply instruction to the composite gas supply component, and the electric airtight valve 22 in the composite inflation component opens, and the high-pressure gas in the high-pressure cylinder 3 quickly inflates the external spherical large air bag 10.
