Description

Technical Field

[0002] When the buoy is working, its underwater sensor needs to choose the appropriate working depth according to different sea conditions to achieve the best submarine search effect. The technical difficulty and advancement of the depth-setting device design are mainly reflected in the design and implementation of the depth-setting wire burning mechanism. In traditional designs, such as foreign products, mechanical depth setting and rotating line-release are used to determine the depth setting length. Its structure is complex and large in size, and it can only set the working depth before being deployed. At present, a detachable mechanical structure is used in China. When in use, the depth-setting device needs to be separated from the surface electronic cabin. The interior of the buoy is a sensitive mechanical structure. When in use, each device needs to be triggered and deployed step by step, which makes the processing difficult and the cost high. Summary of the invention

[0016] like Figure 1 or Figure 2 The sonar buoy depth setting wire burning device shown in the figure, the traditional buoy includes a surface electronic cabin, the surface electronic cabin is connected to the underwater sensor, the buoy is equipped with a power supply and a management system. The sonar buoy depth setting wire burning device includes a depth setting release device which is integrated with the surface electronic cabin and is arranged on the outer bottom surface of the surface electronic cabin. The depth setting release device can release the sensor underwater according to the currently selected depth setting depth.

[0017] Depth release device, specifically:

[0018] It includes multiple burnt wire resistors, each of which corresponds to the release of a working depth. When the buoy is powered on and the management system is started, a burnt wire resistor matching the current depth setting parameter is selected according to the preset depth setting parameter. The matching can be multiple or single. The management system burns out the corresponding burnt wire resistor through the selection circuit in the prior art and releases the sensor according to the preset depth setting parameter.

[0019] Furthermore, the sensor is connected to the surface electronic cabin through a signal line, and the surface electronic cabin communicates with the controller, and also includes a surface electronic cabin shell, a plurality of load-bearing cables, a cover plate and a plurality of burnt-wire circuit boards (PCB burnt-wire circuit boards). The cover plate 1 is sealed on the surface electronic cabin shell, wherein:

[0020] The bottom surface of the shell of the surface electronic compartment is fixed to the outer bottom surface of the surface electronic compartment. A plurality of burn-in circuit boards 5 are installed in the central area of ​​the bottom surface of the shell of the surface electronic compartment. A burn-in resistor is welded on each burn-in circuit board 5. Each load-bearing cable is connected to the corresponding burn-in resistor in a threading manner and is tied with the signal line.

[0021] After the buoy is deployed, the power supply is turned on, and the management system is started. According to the pre-set depth setting parameters, one or more burn-in resistors that match the current depth setting parameters are selected, one or more load-bearing cables are burned out, and the signal line sets the depth of the sensor according to the preset parameters.

[0022] like Figure 3 As shown, the bottom surface of the shell of the surface electronic compartment is symmetrically provided with holes for each load-bearing cable to pass through, and is filled with a grease or silicone grease layer for surface sealing. Because the surface electronic compartment floats on the water surface, the hydrostatic pressure is low, and the grease or silicone grease layer is used to prevent water from entering the shell. The load-bearing cables are made of aramid wire.

[0023] For example, the cover plate 1 is an ABS plate with a length of 80 mm, a width of 67 mm and a thickness of 2 mm; the outer diameter of the surface electronic compartment shell 2 is 116 mm and the height is 143 mm; the burnt-wire resistor 3 has a resistance of 22 ohms; the small screw 4 is a standard fastener of M2.5 stainless steel screw; the burnt-wire circuit board 5 has a width of 12 mm, a length of 38 mm and a thickness of 2 mm; the load-bearing cable 6 is a nylon cable with a diameter of 1 mm; the large screw 7 is a standard fastener of M3 stainless steel screw.

[0024] During assembly, first weld the burn-in resistor 3 to the burn-in circuit board 5, and then assemble the whole into the bottom groove of the surface electronic compartment shell 2, insert the load-bearing cable 6 into the holes at both ends of the burn-in circuit board 5 and pass through the upper end of the burn-in resistor 3, fill the groove with silicone grease, and finally install the cover plate 1 to the bottom surface of the surface electronic compartment shell 2.

[0025] The load-bearing cable control lengths are 10 meters, 20 meters, 30 meters, 40 meters, and 50 meters, with 10 meters being the initial default release length.

[0026] When the sensor depth setting parameter is 20 meters, just burn out the burnt wire resistor corresponding to 20 meters to release the sensor's 20-meter depth setting;

[0027] When the sensor's fixed depth parameter is set to 50 meters, all load-bearing cables are burned out by the corresponding burn-wire resistors, completing the sensor's 50-meter fixed depth release.

[0028] The above are only specific embodiments of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present disclosure should be included in the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be based on the protection scope of the claims.
