Description

Technical Field

[0001] The present invention relates to the field of underwater target detection, and particularly to an underwater device floating and attitude adjustment device. Background Art

[0002] With the development of ocean hydrological monitoring, underwater target detection, and seabed observation technologies, people have a better understanding of the marine ecosystem. Currently, the instrument and equipment used in ocean hydrological monitoring, underwater target detection, and seabed observation technologies usually need to be deployed below the sea surface, complete operations below the sea surface, and be regularly recovered and maintained, so as to collect the data obtained thereby and recycle the core components. In the prior art, after the underwater device completes its operation underwater, divers are required to go underwater to salvage it, resulting in low work efficiency, great salvage difficulty, and high safety risks. It is difficult to achieve automatic floating after receiving a floating instruction and maintain the attitude during the floating process. Summary of the Invention

[0003] The purpose of the present invention is to overcome the deficiencies existing in the prior art, and provide an underwater device floating and attitude adjustment device, which solves the technical problem that in the prior art, after the underwater device completes its operation underwater, divers are required to go underwater to salvage it, greatly reduces the possibility of danger to the staff during this process, improves work efficiency, reduces the salvage difficulty, and ensures the personal safety of the salvage personnel. The principle is simple and effective, and the reliability is high.

[0004] The purpose of the present invention is completed through the following technical solutions: This underwater device floating and attitude adjustment device includes:

[0005] An air cylinder for storing compressed gas;

[0006] An airbag connected to the air cylinder through a pipeline, and an electromagnetic valve is provided on the pipeline. The inlet of the electromagnetic valve is communicated with the air outlet end of the air cylinder, and the outlet of the electromagnetic valve is communicated with the air inlet end of the airbag. The opening and closing of the pipeline are controlled by the electromagnetic valve to fill the airbag with gas;

[0007] A sealed cabin is arranged between the airbag and the air cylinder in a closed manner, and the electromagnetic valve is arranged in the sealed cabin; and

[0008] An electric control component is arranged in the sealed cabin, which is used to receive a floating instruction and control the electromagnetic valve to act through a signal.

[0009] As a further technical solution, an end cover is installed on the side of the sealed cabin close to the airbag.

[0010] As a further technical solution, the electronic control component includes a battery and a main board powered by the battery. A communication module is provided on the main board, which is used to receive the floating-up instruction from the control terminal and send the real-time position to the control terminal; after the communication module receives the floating-up instruction, the main board controls the solenoid valve to act through a signal.

[0011] As a further technical solution, a one-way fixed-differential pressure reducing valve is installed at the exhaust end of the airbag, which is used to discharge the gas in the airbag after the device is recovered.

[0012] As a further technical solution, an airbag lining is arranged inside the airbag.

[0013] The beneficial effects of the present invention are as follows:

[0014] 1. The solenoid valve is used to control the opening and closing of the pipeline between the gas cylinder and the airbag. The gas in the gas cylinder inflates the airbag through the solenoid valve, realizing the overall floating of the device.

[0015] 2. The communication module is set on the main board, which can be remotely controlled by an external terminal, safe and reliable. After the communication module receives the floating-up instruction, the main board controls the solenoid valve to act through a signal, realizing automatic floating, and no longer requires divers to go underwater for operation.

[0016] 3. After the device emerges from the water surface as a whole, it will start the position signal sending program to send the real-time position of the device to the terminal, which is convenient for timely salvage.

[0017] 4. A sealed cabin is arranged between the gas cylinder and the airbag, and the battery, solenoid valve and main board are all arranged in the sealed cabin to keep it airtight and prevent seawater from entering and damaging the electrical components.

[0018] 5. A one-way fixed-differential pressure reducing valve is installed at the exhaust end of the airbag, which can quickly discharge the gas in the airbag after the device is recovered, facilitating repeated use. Description of the Drawings

[0024] The present invention will be described in detail below in conjunction with the accompanying drawings:

[0025] Embodiment: As shown in the attached Figures 1 to 4 figures, this underwater device floating and attitude adjustment device includes a gas cylinder 1, a sealed cabin 2, an end cap 3, a one-way differential pressure reducing valve 4, an airbag 5, a battery 6, a main board 7, an airbag lining 8, and an electromagnetic valve 9.

[0026] Refer to the attached Figure 1 , 3 figures. The gas cylinder 1 is arranged on one side (left side) of the device, and compressed gas (usually compressed air) is stored in the gas cylinder 1. The airbag 5 is arranged on the other side (right side) of the device. The airbag 5 is connected to the gas cylinder 1 through a pipeline, and an electromagnetic valve 9 is provided on this pipeline. The inlet of the electromagnetic valve 9 is communicated with the air outlet end of the gas cylinder 1, and the outlet of the electromagnetic valve 9 is communicated with the air inlet end of the airbag 5. The electromagnetic valve 9 is used to control the opening and closing of the pipeline, so as to fill the airbag 5 with gas. As shown in Figure 2 , 4 figures, preferably, a one-way differential pressure reducing valve 4 is installed at the exhaust end of the airbag 5, which can quickly discharge the gas in the airbag 5 after the device is recovered, facilitating repeated use. Further, an airbag lining 8 is arranged in the airbag 5 to ensure a certain structural strength.

[0027] As shown in Figure 2 figures, a sealed cabin 2 is arranged between the airbag 5 and the gas cylinder 1, so that the sealed cabin 2 is kept airtight with the airbag 5 and the gas cylinder 1. The battery 6, the electromagnetic valve 9, and the main board 7 are all arranged in the sealed cabin to keep sealed, effectively preventing seawater from entering and causing damage to electrical components. Among them, the battery 6 and the main board 7 are used as an electric control component, which can receive the floating instruction and control the action of the electromagnetic valve 9 through signals. Further, the main board 7 is powered by the battery 6, and a communication module is provided on the main board 7. The communication module can receive the floating instruction from an external control terminal and send the real-time position to the control terminal after the whole device floats out of the water surface. When the communication module receives the floating instruction, the main board 7 controls the action of the electromagnetic valve 9 through signals, so as to automatically control the device to float.

[0028] Preferably, as shown in Figure 1 , 3 figures, an end cap 3 is installed on the side of the sealed cabin 2 close to the airbag 5.

[0029] The working process of the present invention:

[0030] During remote floating, the operator remotely issues a floating instruction (which can be done on the deck unit of the mother ship). The communication module on the main board 7 receives the floating instruction, and the main board 7 controls the solenoid valve 9 to act through signals, causing the solenoid valve 9 to open (the pipeline between the gas cylinder 1 and the airbag 5 is opened). The compressed air in the gas cylinder 1 inflates the airbag 5 through the solenoid valve 9. As the airbag 5 expands, the buoyancy of the overall equipment becomes greater and greater. When the equipment becomes positively buoyant, it starts to float until it emerges from the water surface. At this time, by means of the communication module on the main board 7, the real-time position of the device is sent to the control terminal, and then the salvage can begin.

[0031] Through the device provided by the present invention, the staff can remotely control the floating and sinking of the equipment in a safe area, greatly reducing the possibility of danger to the staff during this process and improving work efficiency.

[0032] The present invention realizes the automatic lifting function through an airbag and has the following advantages: The solenoid valve technology is already mature, with many successful application cases and is widely used in the machinery industry. At the same time, with the continuous progress of technology, the performance and reliability of the solenoid valve are also constantly improving. For most machinery, it is technically feasible to use a solenoid valve, with low cost and convenient assembly and maintenance.

[0033] In addition, the present invention has a high degree of automation, a simple structure, and a low manufacturing cost.

[0034] It can be understood that for those skilled in the art, any equivalent replacement or change to the technical solution and inventive concept of the present invention should fall within the protection scope of the appended claims of the present invention.
