Description

Technical Field

[0001] The present invention belongs to the field of water surface detection buoys, and in particular relates to a small buoy coordinated action process testing device and a testing method. Background Art

[0002] The small buoy is carried by a dedicated underwater vehicle and detaches from the vehicle at a designated location. At a certain depth, the deployment section's float bladder inflates, jettisoning the fairing. Simultaneously, the tail section's multi-stage telescopic mechanism, under pressure, cuts through pins, allowing the buoy to deploy step by step. When the buoy's attitude stabilizes, the cylinder inflates the piston chamber, raising the head section's detection device to a predetermined height. The detection device then searches for, captures, and tracks the target, transmitting relevant information about the target and the buoy's own location to the dedicated underwater vehicle.

[0003] To achieve the buoy's ultimate mission objective, it's crucial to ensure the smooth coordinated operation of the float bladder inflation, tail section deployment, and nose section lift. Failure in any of these processes will result in mission failure. Therefore, appropriate testing equipment is required to assess and evaluate the accuracy of the coordinated operation of small buoys. However, accurately testing this coordinated operation within the buoy's small footprint is a technical challenge. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides a small buoy coordinated action process testing device and a testing method thereof, which adds a test section between the small head section and the expansion section to detect the accuracy of the buoy coordinated action process and determine the technical status of the buoy.

[0005] The purpose of the present invention is achieved through the following technical solution: a small buoy coordinated action process testing device, including a head section, a test section and a deployment section.

[0006] The test section is detachably connected between the head section and the expansion section.

[0007] The test section includes a lifting and inflating joint, a test section shell, a float bag inflating joint, a high-pressure pipeline and a telescopic mechanism inflating joint.

[0008] One end of the lifting and inflating joint is connected to the piston cavity of the head section, and the other end is connected to the high-pressure pipeline.

[0009] One end of the float bag inflation joint is connected to the float bag inflation cavity, and the other end is connected to the high-pressure pipeline.

[0010] One end of the telescopic mechanism inflation joint is connected to the expansion section sealing chamber, and the other end is connected to the high-pressure pipeline.

[0011] The high-pressure pipeline includes a high-pressure gas storage cylinder, a test gas cylinder, a solenoid valve, a pressure reducing valve, a stop valve and a pipeline.

[0012] The high-pressure gas storage cylinder is connected to three test gas cylinders through pipelines. Valves are provided on the connecting pipelines to control the gas supply from the high-pressure gas storage cylinder to the three pipelines.

[0013] The high-pressure gas cylinder is inflated through an external gas delivery device.

[0014] The lifting inflation joint, the float bag inflation joint and the telescopic mechanism inflation joint are correspondingly connected to the three test gas cylinders through pipelines.

[0015] The solenoid valve is arranged on the pipeline connecting the test gas cylinder and the joint, and is used to control the gas release of the test gas cylinder to the outside.

[0016] Preferably, the test segment is connected to the head segment and the expansion segment in the radial direction by two rows of screws.

[0017] In addition to providing a small-sized buoy coordinated motion process testing device, the present invention further provides a method for using the small-sized buoy coordinated motion process testing device, which is specifically as follows:

[0018] The high-pressure gas cylinder in the high-pressure pipeline is inflated through an external gas transmission device, and the gas in the cylinder serves as the working gas source of the system.

[0019] When conducting the test, connect the test section between the head section and the deployment section. According to the test requirements, connect the pipelines corresponding to the three test gas cylinders in the high-pressure pipeline to the lifting and inflation joint, float bag inflation joint and telescopic mechanism inflation joint of the test section. Adjust the pressure reducing valve in the high-pressure pipeline to the pressure required for the test, switch to the corresponding test gas cylinder through the valve for inflation, and then control the corresponding test gas cylinder to deflate to the outside through the solenoid valve. Test whether the lifting function of the head section detection device, the float bag inflation to throw away the fairing, and the telescopic mechanism deployment function are normal. After the test, manually depressurize the pipeline through the pressure relief valve to ensure the safety of the test.

[0020] Compared with the prior art, the present invention has the following advantages:

[0021] The present invention provides a small buoy coordinated action process testing device and testing method, which simulates the action performance of the float bag inflation, tail section deployment and head section lifting during the operation of the small buoy by setting a test section between the head section and the deployment section, thereby providing a strong guarantee for determining the technical status of the small buoy and releasing technical risks in advance. The present invention has a simple structure, high reliability, and good economic and military benefits. BRIEF DESCRIPTION OF THE DRAWINGS
