[0021] Compared with the prior art, the bottom-mounted underwater multi-physical field information detection device provided by the present application has an information detection module located on the top-level stereoscopic frame 110, and the top-level stereoscopic frame 110 is a fully open and unobstructed structure, which has a higher perception of the outside world and can more easily monitor underwater information in an all-round and more sensitive manner. Most of the existing similar devices are semi-enclosed or closed structures, and the signal source received by the information detection module is unidirectional. If information is to be monitored in all directions, it is necessary to set up information detection modules in multiple directions; the information detection module of the present application can monitor multi-physical field information such as sound wave signals, depth signals, electric field change signals and magnetic field change signals, and has underwater information fusion monitoring capabilities. The multi-physical field fusion information is transmitted to the industrial computer 620 for processing, and is transmitted back to the surface communication buoy in real time through the underwater acoustic communication machine 640, and then transmitted back to the mother ship, shore base or satellite. In this embodiment, the detection device is seated on the bottom through the anchor block base 300 at the bottom, the anchor block base 300 is plugged and matched with the bottom of the bottom three-dimensional frame 130, and the acoustic releaser 200 and the anchor block base 300 are connected. After the detection device works for a set time, the execution end of the acoustic releaser 200 is opened to release the anchor block base 300, and the main part of the detection device floats under the action of the buoyancy module 500. The mounting frame 100 is divided into a top three-dimensional frame 110, a middle three-dimensional frame 120 and a bottom three-dimensional frame 130. Each layer of the structure has a clear division of labor, which is convenient for installation and debugging, and it is easier to distribute the center of gravity. When the detection device is at the bottom or floating, the posture is more stable, and the position of the bottom and the floating are more accurate. In particular, when the seabed terrain is complex, it is very important for the detection device to be able to accurately sit on the bottom.

[0022] In one embodiment, the top-layer stereo frame 110, the middle-layer stereo frame 120 and the bottom-layer stereo frame 130 are detachably connected together. The top-layer stereo frame 110 includes a frame structure 111 and a mounting plate 112 arranged at the bottom of the frame structure 111. The mounting plate 112 is circumferentially opened with multiple mounting holes 1121 and multiple groups of dispersed mounting screw holes 1122. Some of the mounting holes 1121 are used to install the acoustic wave sensor 410, and some of the mounting screw holes 1122 are used to install the depth sensor 420, the electric field sensor 430, and the magnetic field sensor 440; the middle-layer installation space and the bottom-layer installation space are respectively located in the middle-layer stereo frame 120 and the bottom-layer stereo frame 130.

[0023] Specifically, the top-layer stereo frame 110 and the middle-layer stereo frame 120 are connected by flanges on four corners and corresponding bolts, and the middle-layer stereo frame 120 and the bottom-layer stereo frame 130 are connected by flanges on four corners and corresponding bolts, forming an assembled modular structure, which can be quickly disassembled and assembled, greatly reducing the difficulties and safety hazards of the system during lifting and transportation, and greatly reducing the various costs of the test. In addition, the design of multiple mounting holes 1121 and multiple groups of mounting screw holes 1122 on the mounting plate not only supports multiple combined installation forms of acoustic, magnetic, electrical and other sensors, adjusts the position distance of the mounting matrix, but also can carry any type and any form (including shape) of secondary development, wherein the acoustic wave sensor 410 is a vector hydrophone installed on the mounting hole 1121 through a flange, the depth sensor 420 is connected and fixed to the top surface of the mounting plate by screws and the mounting screw hole 1122, and the magnetic field sensor 440 is connected and fixed to the bottom edge of the mounting plate by screws and the mounting screw hole 1122, and a magnetic field sensor 440 can be installed around the mounting plate. The multiple mounting holes 1121 and the multiple groups of mounting screw holes 1122 are all distributed circumferentially, which is more conducive to adjusting the center of gravity of the detection device without deviation.

[0024] In one embodiment, the middle-layer three-dimensional frame 120 includes a plurality of support columns 121 distributed around the buoyancy module 500, and two mounting plates 122 distributed up and down. The two mounting plates 122 are respectively connected to the two ends of the support columns 121. The mounting plates 122 are provided with a plurality of through holes 1221. The buoyancy module 500 has a through hole 2 (such as Figure 2 As shown, through hole 2 is blocked by mounting plate 2 122 below through hole 1 1221, so it is not shown in the figure), through hole 1 1221 is coaxial with through hole 2, and through hole 1 1221 is coaxial with part of mounting hole 1121. Specifically, in this way, when the detection device sinks and floats, the water flow will pass through the flow channel formed by mounting plate 1, through hole 1 1221 and through hole 2, which has a guiding effect and can reduce the deviation of the detection device.

[0025] In one embodiment, the buoyancy module 500 is provided with a plurality of through holes 3 1222 , both ends of the through holes 3 1222 pass through the two mounting plates 2 122 , and cables for connecting the information detection module and the information integration module are passed through the through holes 3 1222 .

[0026] In one embodiment, a sealed chamber body 2 650 symmetrical to the sealed chamber body 1 610 is disposed in the bottom three-dimensional frame 130, and a backup power supply is disposed in the sealed chamber body 2 650. Such a configuration can balance the center of gravity of the detection device and increase the battery life.

[0027] In one embodiment, a total of four rod bodies 450 are arranged around the mounting plate 112, and an electric field sensor 430 is installed at one end of each rod body 450. Specifically, the four rod bodies 450 extend horizontally in four directions, and the cables connecting the electric field sensors 430 are passed through the rod bodies 450, which can detect underwater magnetic field changes in all directions and detect underwater equipment, such as submarines, more accurately and sensitively. Among them, the rod body 450 can be made of plastic materials such as PVC, PC, PA, PPE, etc., or can be made of metal materials such as steel and aluminum alloy; preferably, the rod body 450 is made of plastic material, which has good toughness and buffering effect to avoid irreversible bending deformation, and the light weight can reduce the overall weight.

[0028] In one embodiment, the middle of the mounting plate 112, the mounting plate 2 122 and the buoyancy module 500 has a through hole in the up-down direction, which is used for the acoustic releaser 200 to be set up in the middle of the mounting frame 100 in an up-down through-type manner. The top of the acoustic releaser 200 is fixedly connected to the middle of the frame structure 111, and the execution end of the acoustic releaser 200 is connected with a chain 201. There are two acoustic releasers 200, and they are respectively connected to the anchor block base 300 through two chains 201. In this way, the acoustic releaser 200 is on the center of gravity axis of the detection device, and can reduce the center of gravity deviation during the whole process of sinking and floating; the function of the two acoustic releasers 200 is that when one acoustic releaser 200 fails, the other can work normally to ensure that the detection device can float and be recovered.

[0029] In one embodiment, two baffles 131 are provided on the bottom three-dimensional frame 130, and the chain 201 is located between the two baffles 131, which can prevent the sound releaser 200 from loosening the chain 201. When the detection device floats up, the chain 201 swings and hits the sealed chamber body 1 610 and the sealed chamber body 2 650, and even gets entangled on the bottom three-dimensional frame 130 and cannot float up.

[0030] In one embodiment, at least four legs 132 are provided at the bottom of the bottom three-dimensional frame 130, each leg 132 is inserted into the anchor block base 300, and each leg 132 is sleeved with a spring 133, and both ends of the spring 133 are respectively in contact with the end of the leg 132 and the anchor block base 300. When the detection device lands on the bottom, the spring 133 acts as a buffer to achieve a soft landing.

[0031] In one embodiment, the information integration module further includes a beacon 660 disposed on the top of the mounting frame 100, and the underwater acoustic communication machine 640 is disposed in the top three-dimensional frame 110. The top middle of the frame structure 111 is fixedly connected with a lifting lug 113 through a base and bolts for lifting the detection device. In this way, the beacon 660 is used for accurate positioning when the detection device is retracted. Preferably, the beacon 660 is fixed to the middle of the frame structure 111 through bolts and a base to reduce the impact on the center of gravity; the underwater acoustic communication machine 640 is disposed in the top three-dimensional frame 110 to reduce obstruction and facilitate smooth communication.
