Detailed Implementation

[0028] like Figures 1-3 As shown, this application provides a bottom-mounted underwater multiphysics information detection device, comprising: a mounting frame 100, an information detection module, a buoyancy module 500, and an information integration module; wherein, the mounting frame 100 includes an open top-layer three-dimensional frame 110, a middle-layer three-dimensional frame 120, and a bottom-layer three-dimensional frame 130, a sound release device 200 is disposed on the top-layer three-dimensional frame 110, and an anchor base 300 is movably disposed at the bottom of the bottom-layer three-dimensional frame 130, the anchor base 300 being connected to the actuating end of the sound release device 200; the information detection module is disposed on the top-layer three-dimensional frame 110, and the information detection module includes an acoustic wave sensor. 410, depth sensor 420, electric field sensor 430, magnetic field sensor 440; buoyancy module 500 is set in the middle layer three-dimensional frame 120; information integration module includes sealed chamber 610 set in the bottom layer three-dimensional frame 130, industrial control computer 620 and power supply 630 set in sealed chamber 610, and underwater acoustic communication device 640 set on mounting frame 100. Industrial control computer 620 is used to collect and process multi-physics field information collected by information detection module and issue commands. Underwater acoustic communication device 640 is used for external communication. Power supply 630 is connected to industrial control computer 620, underwater acoustic communication device 640 and information detection module.

[0029] Compared with the prior art, the bottom-sitting underwater multi-physical field information detection device provided by the application has an information detection module located on the top three-dimensional frame 110, and the top three-dimensional frame 110 is a fully open and unobstructed structure, has higher perception to the outside world, and can more easily and more sensitively monitor underwater information in all directions. The prior similar devices are mostly semi-closed or closed structures, and the signal source received by the information detection module is unidirectional. If the information is to be monitored in all directions, the information detection modules need to be arranged in multiple directions. The information detection module of the application can monitor sound wave signals, depth signals, electric field change signals, magnetic field change signals and other multi-physical field information, has the underwater information fusion monitoring capability, and the multi-physical field fusion information is transmitted to the industrial computer 620 for processing and transmitted back to the water surface communication buoy in real time through the underwater acoustic communication machine 640, and then transmitted back to the mother ship, the shore base or the satellite.

[0030] In the embodiment, the detection device is bottom-sitting through the anchor block base 300, the anchor block base 300 is inserted and matched with the bottom of the bottom three-dimensional frame 130, the sound release device 200 is matched with the anchor block base 300, after the detection device works for a set time, the execution end of the sound release device 200 is opened, the anchor block base 300 is released, and the main part of the detection device is floated up under the action of the buoyancy module 500. The mounting frame 100 has a three-layer structure of the top three-dimensional frame 110, the middle three-dimensional frame 120 and the bottom three-dimensional frame 130, each layer has clear division of labor, is convenient for installation and debugging, and is more easy to distribute the center of gravity. When the detection device is in the lower layer or floats up, the posture is more stable, the bottom-sitting and floating positions are more accurate, and especially when the seabed topography is complex, it is very important for the detection device to accurately sit on the bottom.

[0031] In one embodiment, the top three-dimensional frame 110, the middle three-dimensional frame 120 and the bottom three-dimensional frame 130 are detachably connected together, the top three-dimensional frame 110 includes a frame structure body 111 and a mounting plate one 112 arranged at the bottom of the frame structure body 111, a plurality of mounting holes 1121 and a plurality of groups of mounting screw holes 1122 dispersedly distributed are circumferentially arranged on the mounting plate one 112, part of the mounting holes 1121 are used for mounting the sound wave sensor 410, and part of the mounting screw holes 1122 are used for mounting the depth sensor 420, the electric field sensor 430 and the magnetic field sensor 440; the middle layer mounting space and the bottom layer mounting space are respectively located in the middle three-dimensional frame 120 and the bottom three-dimensional frame 130.

[0032] Specifically, the top-level three-dimensional frame 110 and the middle-level three-dimensional frame 120 are connected by flanges at the four corners and corresponding bolts, and the middle-level three-dimensional frame 120 and the bottom-level three-dimensional frame 130 are connected by flanges at the four corners and corresponding bolts, forming an assembled modular structure that allows for rapid assembly and disassembly, greatly reducing difficulties and safety hazards during lifting and transportation, while also significantly reducing various testing costs. Furthermore, the design of multiple mounting holes 1121 and multiple sets of mounting screw holes 1122 on the mounting plate not only supports various combinations of acoustic, magnetic, and electrical sensors and adjustments to the mounting matrix position and distance, but also allows for secondary development of any type and form (including shape). For example, the acoustic wave sensor 410 is a vector hydrophone mounted on the mounting hole 1121 via a flange; the depth sensor 420 is fixed to the top surface of the mounting plate via screws connected to the mounting screw holes 1122; and the magnetic field sensor 440 is fixed to the bottom edge of the mounting plate via screws connected to the mounting screw holes 1122. One magnetic field sensor 440 can be installed on each of the four sides of the mounting plate. The multiple mounting holes 1121 and the scattered sets of mounting screw holes 1122 are all circumferentially distributed, which is more conducive to adjusting the center of gravity of the detection device to prevent it from shifting.

[0033] In one embodiment, the middle-layer three-dimensional frame 120 includes multiple support columns 121 distributed around the buoyancy module 500 and two mounting plates 122 distributed vertically. The two mounting plates 122 are respectively connected to the two ends of the support columns 121. The mounting plates 122 are provided with multiple through holes 1221, and the buoyancy module 500 is provided with through holes 2 (e.g., ...). Figure 2 As shown, through hole two is blocked by mounting plate two 122 below through hole one 1221 (so it is not shown in the figure). Through hole one 1221 is coaxial with through hole two, and through hole one 1221 is also coaxial with part of mounting hole 1121. Specifically, when the detection device sinks and floats, the water flow will pass through the flow channel formed by the mounting plate, through hole one 1221 and through hole two, which has a guiding effect and can reduce the displacement of the detection device.

[0034] In one embodiment, the buoyancy module 500 has multiple through holes 1222, with two mounting plates 122 passing through both ends of the through holes 1222. Cables for connecting the information detection module and the information integration module are threaded through the through holes 1222.

[0035] In one embodiment, a second sealed chamber 650, symmetrical to the first sealed chamber 610, is provided within the bottom three-dimensional frame 130, and a backup power supply is provided within the second sealed chamber 650. This arrangement can balance the center of gravity of the detection device and improve its battery life.

[0036] In one embodiment, four rods 450 are arranged around the mounting plate 112, and one electric field sensor 430 is installed at one end of each rod 450. Specifically, the four rods 450 extend horizontally in four directions, and the cable connecting the electric field sensor 430 is arranged in the rod 450, which can detect the underwater magnetic field change in all directions and more accurately and sensitively detect underwater equipment such as submarines. The rod 450 can be made of plastic materials such as PVC, PC, PA, PPE, or metal materials such as steel and aluminum alloy. Preferably, the rod 450 is made of plastic material, which has good toughness and buffering effect, avoids irreversible bending deformation, and reduces the overall weight due to its light weight.

[0037] In one embodiment, the mounting plate one 112, the mounting plate two 122 and the buoyancy module 500 have a through hole in the up-down direction in the middle, which is used for the sound release device 200 to be arranged in the middle of the mounting frame 100 in a through-up and down manner. The top end of the sound release device 200 is fixedly connected to the middle of the frame structure 111, the execution end of the sound release device 200 is connected with the chain 201, the number of the sound release device 200 is two, and the two sound release devices 200 are connected with the anchor block base 300 through two chains 201 respectively. In this way, the sound release device 200 is on the gravity center axis of the detection device, and can reduce the gravity center deviation in the whole process of sinking and floating. The function of the two sound release devices 200 is to ensure that the detection device can float and be retrieved when one sound release device 200 fails and the other one works normally.

[0038] In one embodiment, the bottom layer stereo frame 130 is provided with two baffles 131, and the chain 201 is located between the two baffles 131, which can avoid the sound release device 200 from loosening the chain 201, and the chain 201 from swinging and hitting the sealed bin one 610 and the sealed bin two 650, or even winding on the bottom layer stereo frame 130 when the detection device floats up.

[0039] In one embodiment, the bottom layer stereo frame 130 is provided with at least four feet 132, each of which is inserted into the anchor block base 300, and a spring 133 is sleeved on each foot 132. The two ends of the spring 133 are respectively abutted with the end of the foot 132 and the anchor block base 300. When the detection device is on the bottom, the spring 133 plays a buffering role to realize soft landing.

[0040] In one embodiment, the information integration module further comprises a beacon 660 disposed on the top of the mounting rack 100, and the underwater acoustic communication machine 640 is disposed in the top layer of the three-dimensional frame 110. The top of the frame structure 111 is fixedly connected with a lifting lug 113 through a base and bolts in the middle of the top, which is used for lifting the detection device. In this way, the beacon 660 is used for accurate positioning when the detection device is retrieved. Preferably, the beacon 660 is fixed on the frame structure 111 near the middle through bolts and a base, which reduces the influence on the center of gravity. The underwater acoustic communication machine 640 is disposed in the top layer of the three-dimensional frame 110, which can reduce the shielding and facilitate smooth communication.
