Detailed Implementation

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use.

[0032] like Figure 1 and Figure 2 As shown, this embodiment discloses an underwater collision test device, which includes a water tank 1, a collision component, and a driving component 6. A slide rail assembly is detachably installed on the water tank 1 via a fixing clamp 3. The collision component is installed on the slide rail assembly and can move along the length of the slide rail assembly. The collision component is partially placed inside the water tank 1. During the test, water is added to the water tank 1, and the water level is controlled according to the test requirements. The driving component 6 is connected to the collision component. A pressure sensor 9 is fixed on the inner wall of the water tank 1. The driving component 6 drives the collision component to move and contact the pressure sensor 9.

[0033] Continue to observe the appendix Figure 1In this embodiment, the slide rail assembly includes a transmission slide rail 2 and a slider. The slider is movably mounted on the transmission slide rail 2. During installation, each transmission slide rail 2 is equipped with two sliders. The sliders are connected to the slide rails in free fall to reduce friction. The collision component is fixedly connected to the sliders. The transmission slide rail 2 is mounted on the side surface of the water tank 1 through a fixing clip 3. The transmission slide rail 2 is arranged along the length direction of the side surface of the water tank 1. Normally, the water tank 1 is a cuboid. Two transmission slide rails 2 are installed opposite each other on the water tank 1 to support the sliding collision component.

[0034] In some embodiments, the distance between the two sets of slide rail assemblies is adjustable, within the thickness range of the tank wall of the water tank 1. The fixing clamp 3 consists of an arc-shaped mounting piece and two screws. The arc-shaped mounting piece is fixedly connected to the transmission slide rail by bolts. Each screw spirals through the two corresponding sides of the arc-shaped mounting piece. The arc-shaped mounting piece is placed on the tank wall of the water tank 1 with its two sides facing downwards. By rotating the screws, the screws abut against the tank wall of the water tank 1, thus firmly fixing the transmission slide rail. This technical solution design allows for quick fixing and disassembly of the transmission slide rail 2. When adjusting the distance between the two transmission slide rails 2, it is only necessary to rotate the screws to adjust the distance between the two sides of the arc-shaped mounting piece and the tank wall. The adjustment method is simple and convenient, and different length collision components can be quickly switched for use.

[0035] As attached Figure 2 and Figure 3 As shown, in this embodiment, the collision assembly includes a traction frame 4 and a support frame 11. The traction frame 4 is fixed on the slider, and the support frame 11 is connected to the traction frame 4 by four suspension ropes 10. A support housing 12 is fixed to the side of the support frame 11 facing the pressure sensor 9. In actual production, the support frame 11 is a frame structure. Threaded holes are opened in the support housing 12, and the workpiece to be tested is fixed to the surface of the support housing 12 with bolts for relevant underwater collision tests. The distance between the two transmission slide rails 2 is adjusted by the length of the traction frame 4. Under normal circumstances, some counterweights need to be fixed inside the support frame 11. In actual production, counterweights 13 are assembled and fixed to the support frame 11 using weight assembly and fixing belts.

[0036] As attached Figure 2 and 4 As shown, in this embodiment, the rear cross structure of the support frame 11 is a rear limiting tube, and the bottom cross structure is a bottom cross limiting tube. They form the middle installation space for assembling the limiting support counterweight 13. The number and weight of the support counterweight 13 are set in various ways to meet the needs of the test; observe the attached... Figure 5 The two short longitudinal beams inside the middle of the traction frame 4 are assembly beams, and the two long transverse beams are support beams. The four intersection points are used to fix the four suspension ropes 10. It should be noted that the two support beams are arranged parallel and symmetrically between the two assembly beams, so that the entire traction frame 4 is subjected to relatively balanced longitudinal forces. Figure 6 In the process, the four apex recessed openings (top holes) of the bearing shell are used to ensure the flatness of the outer shell. In actual fixing, rivets or screws can be used to fix the bearing shell 4 flat to the side of the bearing frame 11. The middle opening (inner hole) of the bearing shell 4 is used to assemble the workpiece to be tested. The flat bearing shell 4 provides a basis for accurate testing and ensures the accuracy of the test data.

[0037] In this embodiment, a winch is used as the driving component 6. The winch is fixed outside the water tank 1, and the winch's traction hook is connected to the traction frame 4. To facilitate the connection between the traction hook and the traction frame 4, a traction rope 5 is fixed on the traction frame 4. The traction hook is directly hung on the traction rope 5, which is secure and easy to use. The traction rope 5 is made of steel wire rope to ensure its strength. In the collision test, the bearing shell 12 and the pressure sensor 9 are at a distance. The winch is used to pull the bearing shell 12 through the winch rope. To ensure the stability of the winch rope's movement, a suitable pulley 7 is installed on the wall of the water tank 1. The movement of the winch rope needs to be guided and limited by the pulley 7.

[0038] In another embodiment, as shown in the appendix Figure 3 As shown, the installation coordinates (position) of the pressure sensor 9 are adjustable. A fixing frame 8 is provided inside the water tank 1. The fixing frame 8 includes two sets of longitudinal telescopic members 84 and two sets of transverse telescopic members 83. The two sets of transverse telescopic members 83 are fixed parallel to each other between the two sets of longitudinal telescopic members 84. The pressure sensor 9 is fixed to the lower transverse telescopic member 83. The transverse telescopic member 83 includes a mounting rod 81 and a connecting rod 82. The connecting rod 82 is movably inserted into the cavity of the mounting rod 81. Both can move freely to achieve telescopic movement, fixing the pressure sensor 9 to the surface of the mounting rod 81. The mounting rod 81 is threaded with a locking screw 85. After adjusting the relative position of the mounting rod 81 and the connecting rod 82, rotating the locking screw 85 will press and fix them together. Similarly, the structure of the longitudinal telescopic member 84 is the same as that of the transverse telescopic member 83, only the installation position is different. By adjusting (deforming) the transverse telescopic member 83 and the longitudinal telescopic member 84, the position of the pressure sensor 9 can be changed to meet different experimental needs. The adjustment is convenient, and the structural design also ensures the accuracy of position adjustment; thus, to a certain extent, the reliability of the experiment is guaranteed.

[0039] In another embodiment, a testing method was disclosed during the experiment. This method is based on the underwater collision test device described above. The slide rail assembly is fixed parallel to the side of the water tank 1. The workpiece to be tested is fixed on the side of the collision assembly facing the pressure sensor 9, and test water is filled into the water tank 1, with the water level submerging the workpiece to be tested. The driving component 6 is activated to drive the collision assembly to move towards the pressure sensor 9 until the workpiece to be tested collides with the pressure sensor 9. The driving speed of the driving component 6 and the counterweight mass in the collision assembly are adjustable. By changing the test parameters, tests can be conducted under different working conditions.

[0040] In actual production, an industrial camera can be installed in the water tank 1 to record video in the direction of the pressure sensor 9. The drive unit 6, the pressure sensor 9, and the industrial camera are connected to the control center (computer) via cables. At this time, the workpiece to be tested is fixed on the bearing housing 12. The position of the pressure sensor 9 and the initial position of the workpiece to be tested are adjusted. The winch selected in this embodiment can switch between traction speeds of 0.25m / s and 0.5m / s. The bearing frame 11 can realize collision conditions with no counterweight, 25kg counterweight, 50kg counterweight, 75kg counterweight, and 100kg counterweight. The drive unit 6 is started to pull the traction frame 4 to move, so that the workpiece to be tested collides with the pressure sensor 9. The test status is recorded by the industrial camera. By changing the counterweight and other operations, tests under different working conditions can be realized. The test data is connected to the control center for analysis and storage.
