[0033] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.
[0034] As Figure 1 shown, a speed adjustment push plate device for a ship model collision test includes a seat frame 2, a push plate 3, a spring 4, and a stretching mechanism 5; the seat frame 2 is used to install the push plate 3, the spring 4, and the stretching mechanism 5; the push plate 3 is slidably connected to the seat frame 2 and is used to push the ship model 1; the spring 4 connects the seat frame 2 and the push plate 3; the stretching mechanism 5 is connected to the push plate 3.
[0035] In this embodiment, as Figure 1 shown, the seat frame 2 is of a U-shaped structure, and the push plate 3 is located in the middle of the U-shaped structure.
[0036] In one embodiment, as Figure 1 shown, a scale 2-1 parallel to the moving direction of the push plate 3 is provided on the seat frame 2.
[0037] In one embodiment, as Figure 1 shown, a hook 3-1 is provided on the back of the push plate 3 for connecting the stretching mechanism 5.
[0038] In one embodiment, as Figure 1 shown, when the stretching mechanism 5 stretches the push plate 3 to move backward relative to the seat frame 2, the spring 4 is in a stretched state.
[0039] In other embodiments, when the stretching mechanism 5 stretches the push plate 3 to move backward relative to the seat frame 2, the spring 4 can also be in a compressed state.
[0040] In one embodiment, as Figure 1As shown, the stretching mechanism 5 includes a pulling rope 5-1 and a rotating shaft 5-2. The pulling rope 5-1 is connected to the push plate 3. A winding drum 5-3 and a rocker 5-4 are provided on the rotating shaft 5-2. The pulling rope 5-1 is wound around the winding drum 5-3. The diameter of the rocker 5-4 is larger than that of the winding drum 5-3, which makes it easier for manual operation to tighten the pulling rope 5-1 more labor-saving. The rocker 5-4 is arranged on one side of the seat frame 2 with a scale 2-1, which is convenient for collecting the pulling rope 5-1 and confirming whether the push plate 3 reaches the preset scale at the same time.
[0041] In one embodiment, as Figure 1 shown, the rotating shaft 5-2 is further connected with a motor 5-5, which can save manpower and improve the automation level.
[0042] In one embodiment, as Figure 2 shown, a locking pin 5-2-2 is provided on the shaft seat 5-2-1 of the rotating shaft 5-2. After stretching in place, the locking pin 5-2-2 can be tightened so that the pulling rope 5-1 will not be released. Ensure that the push plate 3 remains stable during the test.
[0043] In one embodiment, a pair of electromagnets 5-6 are provided on the pulling rope 5-1. Designing electromagnets 5-6 on the pulling rope 5-1 can quickly release the push plate 3 when needed, which is not only convenient for operation, but also avoids the entanglement and damage that may be caused by traditional ropes, improving the safety of the test.
[0044] In one embodiment, a flexible material layer, such as a rubber layer, is provided on the surface of the push plate 3 facing the ship model 1, which can protect the ship model 1 in the collision test, reduce damage, and at the same time protect the push plate 3 itself, extending the service life of the device.
[0045] When the device is in use, shake the rocker 5-4 to pull the push plate 3 backward to a specific position through the pulling rope 5-1, and fix it at the preset scale with the locking pin 5-2-2. Press the stern of the ship model 1 tightly against the push plate 3, and then manually release or electrically release the push plate 3 through the electromagnet 5-6. The ship model 1 will move forward at a preset speed under the push of the push plate 3. By adjusting the stretching length of the spring 4 and corresponding to the corresponding scale, different initial velocity settings can be achieved, so as to simulate different collision conditions.
[0046] To sum up, the utility model uses the elastic force released by the stretching spring 4 to drive the push plate 3, and then pushes the ship model 1 to conduct a collision test. This method not only simplifies the structure of the test device, reduces the number of operators, but also improves the flexibility and efficiency of the test.
