The suspension beams 104 intersect each other perpendicularly and divide the breeding area 101 into 6-8 boxes 105. The boxes 105 are used to install breeding cages 102. The outer periphery of the box opening of the breeding cage 102 is provided with a card edge 106 protruding outward. When the box body of the breeding cage 102 is a hollow structure, when its bottom is inserted into the box slot 105, the card edge 106 can be aligned with the top surface of the suspension beam 104. The aquaculture cages 102 are fixed and limited by each other, and a number of handles 107 are welded on the clamping edge 106 to facilitate the taking and placing of the cages. Different types of fish can be placed in different aquaculture cages 102 during the experiment; a plurality of first buoyancy boxes 103 are fixedly installed at the bottom of the test float 100, and each first buoyancy box 103 is distributed around the periphery of the aquaculture area 101; a first fence 110 and a second fence 111 are installed on the top of the test float 100, and the first fence 110 and the second fence 111 form a "U" shape structure. The first fence 110 is arranged around the periphery of the breeding area 101, and the second fence 111 is arranged around the periphery of the test float 100. Slots 108 are respectively opened at both ends and both sides of the test float 100. The slots 108 are parallel to the sides of the test float 100 and penetrate the top and bottom surfaces of the test float 100. The wave-blocking curtain 300 can be inserted into the slots 108 for fixation. The wave-blocking curtain 300 includes a mesh frame 301 and an air bubble film 304. A plurality of mesh holes 302 are opened in the middle of the mesh frame 301. The top of the mesh frame 301 is welded. There is a baffle 303, which is perpendicular to the end of the mesh frame 301. The other end of the mesh frame 301 can be inserted into the slot 108 and limited by the baffle 303; the bubble film 304 is detachably wrapped on the mesh frame 301 through the pressure strip and covers each mesh hole 302; a pair of fixed connecting rods 109 are also welded at both ends of the test float 100, one end of the fixed connecting rod 109 is welded to the end of the test float 100, and the other end of the fixed connecting rod 109 extends outward from the end of the test float 100.

[0040] There are two floating bridges 200 and they are connected to the two ends of the test float 100 by fixed connecting rods 109. The floating bridge 200 is composed of multiple single-segment floating bodies 201. The head and tail of each single-segment floating body 201 are connected to each other in sequence and can be freely disassembled. The single-segment floating body 201 includes: a rectangular frame 202, a second pontoon 204, a U-shaped rod 205 and a handrail 206; a slot 203 is provided at the bottom of the rectangular frame 202, and the second pontoon 204 is installed in the slot 203, symmetrically on both sides of the rectangular frame 202. Multiple first sleeves 207 are welded, and the axis of the first sleeve 207 is in a vertical state. The two ends of the U-shaped rod 205 can be inserted into the first sleeve 207 and locked and fixed by the first bolt 208, and the two ends of the U-shaped rod 205 can continue to extend upward from the top of the rectangular frame 202, and are fixedly connected to the handrail rod 206 by bolts to form a handrail structure. The middle part of the U-shaped rod 205 abuts against the bottom of the second buoyancy box 204 so that the second buoyancy box 204 can be tightened and fixed in the slot 203.

[0041] In addition, two second sleeves 209 are welded at both ends of the rectangular frame 202. The axis of the second sleeve 209 is horizontal and parallel to the side of the rectangular frame 202. The two adjacent single-section floats 201 are connected by a movable connecting rod 211. The two ends of the movable connecting rod 211 can be respectively inserted into the second sleeves 209 of the adjacent rectangular frames 202 and locked and fixed by second bolts 210. The second sleeve 209 on the outer side of the single-section float 201 at the end of the floating bridge 200 can also be mutually engaged with the fixed connecting rod 109 at the end of the test floating body 100, and locked and fixed by the second bolts 210, so that the floating bridge 200 and the test floating body 100 are connected to each other.

[0042] Next, a method for using an underwater blasting test platform in this embodiment is described in detail to enable those skilled in the art to better understand the present invention:

[0043] When conducting experiments, operators can determine the length of the floating bridge 200 and the position of the test float 100 according to the requirements of the experimental design, and then can assemble single-section floats 201 and splice single-section floats 201 to form a floating bridge 200 at any time, thereby realizing modular free construction.

[0044] In order to verify the impact of the blast shock wave on aquatic organisms, different species of fish and other aquatic animals can be placed in different breeding cages 102, and then each breeding cage 102 is installed in each tank 105 and immersed in water.

[0045] According to the location of the blasting point and the design requirements of the experiment, the installation quantity and position of the wave-blocking curtain 300 can be adjusted arbitrarily. The installation principle is that the wave-blocking curtain 300 is installed between the blasting point and the breeding area 101. If it is necessary to test the impact of the bubble curtain on aquatic organisms, the bubble film 304 on the wave-blocking curtain 300 can be removed, and the bubble tube body of the bubble curtain can be directly installed on the net frame 301, so that the form of different curtains can be easily changed, thereby obtaining more experimental verification information.

[0046] The floating bridge 200 can not only provide a water platform for the test float 100, but also can suspend explosives and sensors under the floating bridge 200, so as to fix the distance between the blasting point, the sensor and the test float 100, making the experimental data more accurate.

[0047] In summary, the underwater blasting test platform in this embodiment is capable of captive breeding of aquatic organisms in the experimental waters by arranging multiple breeding cages 102 in the test float 100. Explosives and sensors can be installed under the floating bridge 200. By changing the number of single-section floats 201, the distance between the blasting point and the breeding area 101 can be flexibly changed, thereby verifying the impact of the blasting shock wave on the aquatic organisms. A detachable wave-blocking curtain 300 is arranged around the test float 100, thereby verifying the weakening effect of the wave-blocking curtain 300 at different directions and distances on the shock wave.
