Description

Technical Field

[0001] The utility model relates to the field of shipwreck salvage, in particular to a buoy device for quickly salvaging sunken objects. Background Art

[0002] China Patent Publication (Announcement) No.: CN105620683A, Patent Title: A rubber salvage buoy, comprising a cylindrical rubber body with hemispherical rubber heads integrally connected at both ends. The outer ends of the rubber heads are connected to flanged housings, which contain a buffer cavity. The outer end faces of the flanged housings are provided with an inflation check valve, a shut-off valve, and a safety valve, all connected to the buffer cavity. The rubber head ends are integrally connected to an air nozzle, one end of which is connected to the rubber body and the other end to the buffer cavity. The invention provides functions such as inflation leakage prevention, automatic exhaust, and emergency exhaust valve assembly protection. When working underwater, the external pipeline on the water surface is connected to the rubber cylinder 1, and the inflation check valve 7 of the inflation control valve group 2 at both ends is used to inflate the two ends of the rubber cylinder 1 at the same time. The gas enters the rubber cylinder 1 through the inflation check valve 7, the rubber cylinder 1 expands, and the internal pressure increases. When the inflation pressure of the rubber cylinder 1 reaches the opening pressure set by the safety valve 9, exhaust begins, and the internal pressure of the rubber cylinder 1 maintains the set working pressure; the buoyancy of the buoy reaches the designed value, and the salvage buoy is lifted. As the salvage buoy rises, the external water pressure changes, the internal pressure in the rubber cylinder 1 increases, the gas expands, and the safety valve 9 continues to exhaust. As the internal and external pressure difference increases, the exhaust speed and exhaust volume are gradually increased to maintain a small change in the internal pressure, ensuring the pressure safety of the rubber cylinder 1. After it rises to a suitable height and stops, the internal pressure drops to the set pressure: during work, if the safety valve 9 fails and cannot exhaust, the lifting is suspended and the stop valve 8 is opened to exhaust.

[0003] The device primarily consists of an inflatable rubber float, an air chamber, and a buoyancy compartment as the main structure; an air intake and exhaust system to control the float pressure; and a net and sling system to form a salvage system. While inflatable rubber floats perform well in both surface and underwater operations in oceans, inland rivers, and lakes, they also present several challenges. First, the rubber material can be affected by water and weather over time, leading to aging and cracking, which can affect the stability and safety of the equipment. Furthermore, due to its smooth and elastic properties, rubber is difficult to bond to fabric. Consequently, a net and sling connection method is employed. However, this method is significantly affected by external forces such as currents and waves, causing the equipment to shift and increasing the difficulty of salvaging. Second, the rubber floats are large, weighing 2.5 tons, and their slow inflation and cumbersome operation prevent them from quickly and effectively recovering sunken objects, delaying rescue efforts. Furthermore, their large size limits their application range and limits their suitability to deep waters. Summary of the Invention

[0004] The purpose of the utility model is to provide a buoy device for quickly salvaging sunken objects, so as to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the utility model is achieved through the following technical measures: a buoy device for quickly salvaging sunken objects, characterized in that it is composed of a buoy system and a pneumatic control system, the buoy system includes an airbag buoy body, a webbing buckle is provided on the outer peripheral wall of the airbag buoy body, the webbing buckle is used to pass through the stress-bearing webbing, the front end of the stress-bearing webbing is provided with a quick detachment buckle, the other end of the quick detachment is connected to the sunken object, the airbag buoy body is provided with an inflation and deflation valve, a pressure relief valve and a quick inflation connector, the quick inflation connector is connected to the pneumatic control system, the pneumatic control system includes a high-pressure air circuit connected to the quick inflation connector, the other end of the high-pressure air circuit is connected to a manual bottle head valve, the manual bottle head valve is connected to a carbon fiber high-pressure gas cylinder, and the material of the airbag buoy body is TPU material.

[0006] Compared with existing technologies, this utility model offers advantages: Because traditional rubber materials can be affected by water and weather over time, leading to aging and cracking, which can impact the stability and safety of the equipment, the airbag float body is constructed from TPU, a material known for its high strength, toughness, wear resistance, cold resistance, oil resistance, water resistance, and aging resistance. This novel structure incorporates a float system and pneumatic control system. A manual valve opens the carbon fiber high-pressure gas cylinder, resulting in rapid inflation, simple operation, fast and efficient response, and a compact size suitable for a wide range of applications.

[0007] As an improvement to the present invention, the airbag float body is composed of two independently controlled airbag float units. This design is chosen for its purpose: if one unit fails, the other can still operate normally, ensuring the smooth implementation of rescue operations.

[0008] As an improvement to the present invention, the manual cylinder valve includes a valve body with a puncture needle disposed therein. This design is used to pierce the copper seal on the carbon fiber cylinder, allowing the high-pressure gas in the carbon fiber cylinder to enter the airbag float body through the outlet adapter and high-pressure gas pipe, achieving rapid inflation and molding.

[0009] As an improvement to the present invention, the needle has a puncture section at the front, a piston section in the middle, and a pin hole at the rear. This design is chosen for the following reasons: the puncture section is used to pierce the copper film seal on the carbon fiber gas cylinder; the piston section is used to control the linear movement of the needle; and the pin hole is used to pass a latch, allowing the needle to remain stationary under the action of a compression spring. During operation, when the latch is removed, the needle moves downward under the force of the compression spring, piercing the copper film seal on the gas cylinder.

[0010] As an improvement to the present invention, there are two pistons, each with a first sealing ring. This design is chosen for the following reasons: the two pistons further ensure linear movement, and the first sealing ring prevents the high-pressure gas in the carbon fiber cylinder from seeping into the upper portion of the needle.

[0011] As an improvement to the present invention, the puncture portion is provided with a groove. The purpose of selecting this design is that when the puncture needle pierces the copper film seal of the carbon fiber gas cylinder, the high-pressure gas in the carbon fiber gas cylinder will pass through the gap in the groove, flow to the gas outlet adapter, pass through the high-pressure gas pipe, and enter the airbag float body.

[0012] As an improvement to the present invention, the bottle valve is a pneumatic valve, comprising a valve body, a plunger disposed within the valve body, and an upper cover threadedly attached to the upper end of the valve body. The upper end of the upper cover is connected to an air pipe. This design is chosen for its purpose of achieving pneumatic control by moving the plunger through air pressure in the air pipe.

[0021] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0022] Example 1

[0023] Please refer to Figure 1 -5. This embodiment provides a buoy device for rapidly recovering sunken objects, comprising a buoy system and a pneumatic control system. The buoy system includes an airbag buoy body 1, the outer wall of which is provided with a webbing buckle 2 for passing through a load-bearing webbing 3. The front end of the load-bearing webbing 3 is provided with a quick-release buckle 4, the other end of which is connected to the sunken object. The airbag buoy body 1 is provided with an inflation and deflation valve 5, a pressure relief valve 6, and a quick-inflation connector 7, which is connected to the pneumatic control system. The pneumatic control system includes a high-pressure gas circuit 8 connected to the quick-inflation connector 7, the other end of which is connected to a manual cylinder valve 9, which is connected to a carbon fiber high-pressure gas cylinder 10.

[0024] The airbag float body 1 is made of TPU, a material with high strength, outstanding load-bearing capacity, impact resistance, and shock absorption. It also has good processability and can be processed using common thermoplastic processing methods. It is also wear-resistant, oil-resistant, and low-temperature resistant.

[0025] In the embodiments of the present invention, please refer to Figure 1 The airbag float body 1 is composed of two independently controlled airbag float units. Each of the two independently controlled airbag float units is equipped with an inflation and deflation valve 5, a pressure relief valve 6, and a quick inflation connector 7. If one unit suddenly fails, the other unit can still operate normally, ensuring the normal operation of the rescue.

[0026] In the embodiments of the present invention, please refer to Figure 2 and Figure 3The manual bottle head valve 9 includes a valve body 11, and a puncture needle 12 is arranged in the valve body 11. The front end of the puncture needle 12 is provided with a puncture part 13, the middle is provided with a piston part 14, and the rear end is provided with a pin hole 15. The puncture part 13 is used to break through the cylinder copper film head 21 on the carbon fiber gas cylinder; the piston part 14 is used to control the linear movement of the puncture needle 12; the pin hole 15 is used to pass through the pin 18, so that the puncture needle 12 remains stationary under the action of the compression spring 19. When working, the pin 18 is removed, and the puncture needle 12 moves downward under the action of the compression spring 19, breaking through the cylinder copper film head 21, and the high-pressure gas in the carbon fiber gas cylinder enters the airbag float body 1 through the gas outlet adapter 20 and the high-pressure gas pipe, thereby realizing rapid inflation and molding.

[0027] In the embodiments of the present invention, please refer to Figure 3 There are two piston parts 14, each of which is provided with a first sealing ring 16. The two piston parts 14 can further ensure the linearity of movement. The first sealing ring 16 is provided on the piston part 14 to prevent the high-pressure gas in the broken carbon fiber cylinder from penetrating into the upper half of the space of the puncture needle 12.

[0028] In the embodiments of the present invention, please refer to Figure 4 The puncture portion 13 is provided with a groove 17. When the puncture needle 12 breaks through the copper film seal 21 of the carbon fiber gas cylinder, the high-pressure gas in the carbon fiber gas cylinder will pass through the gap of the groove 17, flow to the gas outlet adapter 20, pass through the high-pressure gas pipe, and enter the airbag float body 1.

[0029] In the embodiments of the present invention, please refer to Figure 5 , the carbon fiber high-pressure gas cylinder can also be controlled by a pneumatic cylinder head valve, which can achieve semi-automatic control compared with the manual cylinder head valve. Furthermore, the pneumatic cylinder head valve includes an upper cover 23, and a third sealing ring 26 is provided between the upper cover 23 and the valve body 14 to achieve sealing, and a needle 12 is provided in the valve body 14. The front end of the needle 12 is provided with a puncture part 13, and the rear end is provided with a second sealing ring 25. During operation, the external gas pushes the needle 12 downward through the air pipe 22, breaking the copper film seal 21 of the gas cylinder, and the high-pressure gas in the carbon fiber gas cylinder enters the air bag float body 1 through the gas outlet adapter 20 and the high-pressure gas line 8, thereby achieving rapid inflation and molding. When there is no air pressure, the needle 12 is reset under the restoring force of the spring 24.

[0030] This embodiment provides a buoy device for quickly salvaging sunken objects. During normal use, a diver brings the airbag float body 1 to the location where underwater salvage is required, fixes the airbag float body 1 at a suitable location for the sunken object, and then connects the high-pressure air pipe to the airbag float body 1. After ensuring that there is no problem with the airbag float body 1, the crew on board starts to control the manual bottle head valve 9, which opens the carbon fiber high-pressure gas cylinder 10 to release carbon dioxide, which is transmitted to the airbag float body 1 through the high-pressure gas line 8. After the airbag float body 1 is inflated to the rated pressure in a short time, the pressure relief valve 6 automatically starts to work to discharge excess gas, and the buoyancy generated by the airbag float body 1 causes the sunken ship or sunken object to float to the surface.

[0031] The beneficial effects of the present utility model are as follows: the device provides controllable buoyancy for the salvage of sunken ships and sunken objects, and it can quickly handle emergency rescue of sudden and catastrophic events in rivers and lakes. Among them, the airbag float body 1 is made of TPU material, which has the characteristics of high strength, wear resistance, oil resistance, and low temperature resistance; it can provide a large amount of buoyancy safely and stably in a short time, and the device is convenient and fast, with less preparation time, high efficiency and can effectively reduce the rescue time, and is less affected by environmental factors, and can work normally in low-temperature waters. A webbing buckle 2 is added, and the force-bearing webbing 3 passes through the webbing buckle 2. This fixed connection method can firmly fix the airbag float body 1, ensuring that the airbag float body 1 can work normally when affected by water flow during underwater operations. The entire system device is safe and stable, easy to carry, and easy to operate.

[0032] Because traditional rubber materials can be affected by water and weather over time, leading to aging and cracking, which can impact the stability and safety of the device, the airbag float body 1 is made of TPU, a material with high strength, excellent toughness, and resistance to wear, cold, oil, water, and aging. This novel structure includes a float system and a pneumatic control system. A manual cylinder valve 9 opens the carbon fiber high-pressure gas cylinder 10, resulting in rapid inflation, simple operation, fast and efficient response, and a compact size suitable for a wide range of applications.
