Description

Technical Field

[0001] The utility model relates to the technical field of ship equipment, in particular to an unpowered three-dimensional target ship. Background Art

[0002] A target ship is an important ship equipment with special military purposes. It is mainly used as a surface target for anti-ship weapon systems (such as artillery, anti-ship missiles, etc.) to attack, to test the guidance capability or attack effect of the weapon system under test (i.e., the anti-ship weapon system). In other words, the role of the target ship is to test the performance of the weapon system under test.

[0003] After searching the patent document with the publication number CN114906277A, the patent document discloses "a recyclable double-float non-powered three-dimensional target ship. This device effectively simulates the towering equipment targets on the ship through the setting of the mast assembly in the three-dimensional target ship, and has the characteristics of realistic simulation of target characteristics; since the target size and angle corresponding to each mast assembly are adjustable, it can adapt to target ship shooting training of different sizes; since the stern structure cabin of the float is the same as the middle structure cabin, some parts of the float are universal. After shooting, the undamaged stern structure cabin or the middle structure cabin can be disassembled and reassembled, which is conducive to enhancing the maintainability of the target ship after shooting damage, and some parts of the float can be recycled for many times, effectively reducing costs";

[0004] However, the target ship of the above-mentioned device has a fixed shape. Therefore, when the strike test of the weapon system needs to drop the target ship to a longer distance, the target ship will look smaller, making it difficult to carry out aiming tests on some weapon systems that are not equipped with high-power positioning sights. Utility Model Content

[0005] The purpose of the utility model is to provide a non-powered three-dimensional target ship in order to solve the above problems.

[0006] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0007] An unpowered three-dimensional target ship comprises a fish frame, a wind mechanism for enabling the device to move with the help of wind is installed above the fish frame, and a floating mechanism for enabling the device to float on the water surface;

[0008] The floating mechanism includes a bidirectional screw, which is rotatably connected to one end of the fish frame, and a limiting rod is fixed to the other end of the fish frame. The front and rear ends of the bidirectional screw and the limiting rod are both provided with expansion frames, the bidirectional screw is threadedly connected to the expansion frame, the limiting rod is slidably connected to the expansion frame, two lower extension plates are fixed to the corresponding ends of the two expansion frames, a floating plate is fixed to the lower end of the expansion frame, a turntable is fixed in the middle of the bidirectional screw, a plurality of through holes are evenly opened on the outer ring of the turntable, a threaded plug rod is provided in the middle of the uppermost through hole, and a nut is threadedly connected to one end of the threaded plug rod.

[0009] Preferably, the bottom of the uppermost through hole is flush with the uppermost end of the fish skeleton, and the floating plate is made of foam material.

[0010] Preferably: a convex block is arranged at the upper end of the lower extension plate, and the convex block on the lower extension plate is slidably connected to the branch in the middle of the fish frame.

[0011] Preferably: a circular plate with a larger diameter than the threaded rod is arranged at one end of the threaded rod, and a plurality of grooves are provided on the outer ring of the rotating disk and the nut.

[0012] Preferably, the wind power mechanism comprises a plurality of upper extension frames, wherein the upper extension frames are fixed to the upper ends of the outer extension frames, and canvas is fixed between two corresponding upper extension frames.

[0013] Preferably, the canvas is made of polyester and the color of the canvas is red.

[0014] The beneficial effects compared with the prior art are as follows:

[0015] Before using this device, the device is adjusted according to the distance of the device being released. If the release distance is short, the device can be released directly. If the release distance is far, first unscrew the nut from the threaded rod, and then take out the threaded rod. Through the threaded connection between the expansion frame and the two-way screw rod and the sliding connection between the expansion frame and the limit rod, the two expansion frames can be moved in opposite directions by rotating the turntable, thereby increasing the distance between the two expansion frames. In this way, the size of the entire device is enlarged, so that the device can be adjusted as needed. In this way, the situation where the device looks smaller after being released at a long distance can be avoided. BRIEF DESCRIPTION OF THE DRAWINGS
