Description

Technical Field

[0001] This utility model belongs to the field of underwater explosion and damage testing technology, and relates to a device for underwater distance-adjustable power testing. Background Technology

[0002] Underwater explosion testing of munitions, as an important research method, is gradually becoming systematic in practice. Most underwater explosion damage tests are conducted in wells, pools, or tanks, which limits the testing environment and restricts the scale and accuracy of the tests. Current technology lacks dedicated testing platforms; the warhead and target are typically installed and then directly hoisted into the nearshore area or towed to a predetermined location for testing. This lack of a large platform makes operation inconvenient, hinders the positioning of the testing equipment, and allows the equipment to rotate or shift due to environmental factors. Furthermore, the immersion depth cannot be well controlled, leading to errors in data acquisition and significantly impacting test accuracy.

[0003] A Chinese invention patent with publication number CN112213357B discloses a floating platform capable of conducting underwater explosion damage tests in large water areas. The platform includes a floating platform body, a gantry, a lift, a target, a ballast section, an assembly base, a deployment cable, a load-bearing cable, and a restrictive detonating cord. The target is connected to the ballast section. The gantry is installed in the middle of the floating platform body. One end of the deployment cable is fixed to the gantry, and the other end passes through a notch on the floating platform body below the gantry and connects to the target. The lift controls the lowering of the deployment cable and the retrieval of the target. The length of the deployment cable is slightly longer than the specified detonation depth, ensuring that the cable is not stressed during the test detonation. One end of the load-bearing cable is fixed to the floating platform body, and the other end connects to the target. The load-bearing cable includes… At least two cables, symmetrically arranged, are used to fix the relative position of the target and the floating platform; the length of the load-bearing steel cable is set according to the specified detonation depth to control the target's water immersion depth and bear the target's weight during test detonation; the unloading process is stopped when the load-bearing steel cable is fully stressed during target unloading; one end of the restrictive detonating cord is fixed to the floating platform body and connected to the detonating tube when testing is required, and the other end is connected to the test detonation source set on the target; N anchoring buoys are connected to the floating platform body at equal intervals; when the floating platform body floats in the water, the connecting cables between the N anchoring buoys and the floating platform body are straightened to form N equidistant anchoring points, restricting the movement and rotation of the floating platform; N is a positive integer greater than or equal to 3.

[0004] The existing technology has the following technical defects:

[0005] The above technical solution can test the explosive performance of explosives in water, but its explosion source is fixed inside the target. However, underwater munitions such as torpedoes, mines, and depth charges will not explode completely inside the target. They are usually detonated at the edge of the target or at a certain distance from the target. The above technical solution cannot conduct explosion experiments at different positions and distances between the warhead and the target. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a device for underwater distance adjustable power testing.

[0007] The device for underwater distance-adjustable power testing described in this utility model includes a floating platform support and a floating platform body. The floating platform body is provided with lifting lugs and a lifting frame. A hand-cranked hoist is connected to the lifting frame, and a lifting rope is connected to the hand-cranked hoist. The lifting rope passes through the floating platform body and is connected to an effect target. An adjustment component is provided on the effect target, and a bracket is connected to the adjustment component. A warhead is fixedly connected to the bracket.

[0008] Working process or working principle:

[0009] Before the test, the floating platform was placed on the floating platform support. The effect target was suspended below the floating platform using a hand-cranked hoist on the gantry, and the warhead was then fixed on the bracket. At this time, the floating platform was lifted by a crane and slowly and steadily placed on the water surface. The effect target was then placed underwater at a certain distance using a hand-cranked hoist. After the warhead exploded, the effect target was pulled up using a hand-cranked hoist, and the floating platform was lifted by a crane and slowly and steadily placed on the floating platform support. The effect target was then retrieved and damage data was collected.

[0010] The adjustment assembly includes a connecting plate fixed on the effect target, and two ends of the bracket are fixed to the connecting plate by nuts. The two ends of the bracket are threaded, and the distance between the bracket and the connecting plate is adjusted by rotating the two nuts on the bracket.

[0011] The floating platform body is provided with at least three lifting lugs, and lifting lugs are also provided on all four sides of the floating platform body. By setting multiple lifting lugs, the floating platform body is more stable when being lifted.

[0012] The aforementioned hanger has 7 lifting holes, and a hand-cranked hoist is attached to the lifting holes.

[0013] The bottom of the floating platform is fixedly connected to a rubber plate, which serves to buffer, waterproof, and prevent rust.

[0014] The effect target is equipped with a suspension plate corresponding to the suspension rope.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] The warhead of this invention is fixed at a specific position on the effect target by a bracket, and explosion experiments at different distances are achieved by adjusting the distance. This experimental device system is simple to manufacture and easy to operate, and can meet the needs of underwater warhead power testing at different distances, greatly reducing testing costs and improving testing efficiency.

The adjustment component includes a connecting plate fixed to the effect target. Both ends of the bracket are fixed to the connecting plate by nuts. The two ends of the bracket are threaded. The distance between the bracket and the connecting plate is adjusted by rotating the two nuts on the bracket. The floating platform body is provided with at least three lifting lugs, and lifting lugs are also provided on all four sides of the floating platform body. The multiple lifting lugs make it more stable when lifting the floating platform body. The lifting frame is provided with seven lifting holes, and the hand-cranked hoist is hung in the lifting holes.
