[0020] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] like Figure 1The device shown is used to prevent ricochets during high-speed projectile testing on an underwater target course. The device structurally consists of a movable target plate 1 and a hydraulic lifting mechanism 2. The movable target plate 1 comprises a main frame A and an insertable target plate B, and is responsible for decelerating and intercepting ricochets that accidentally fly out of the water. The hydraulic lifting mechanism 2 comprises a hydraulic station 4 and a hydraulic cylinder 3, and is used to raise / lower the interception height of the movable target plate 1.

[0022] like Figure 1 The device shown is used to prevent ricocheting during high-speed projectile testing on an underwater target course. A total of four interception points are set on the infrastructure on both sides of the underwater target course. The device needs to be equipped with four sets of movable target plates 1, eight hydraulic cylinders 3, and one hydraulic station 4.

[0023] like Figure 2 、 3 The main frame A shown provides structural strength and rigidity for the inserted target plate B, and also plays a supporting and fixing role to facilitate lifting and movement, and to facilitate the lifting and adjustment of the hydraulic cylinder 3. The frame body A1 is composed of 60 square steel, and 40 square steel pipes are used as diagonal braces A2 between the upper and lower beams to form a truss structure; the target groove A3 is made of 10# channel steel in the middle, and the lifting legs A4 are made of 10mm steel plates on both sides of the frame to withstand the thrust of the hydraulic cylinder 3 to drive the overall structure up and down. Removable target plate lifting ears A5 are provided on both sides of the frame body A1, which are used to lift the car crane and install it above the preset interception point. After the overall frame is completed, its surface is sprayed with plastic to prevent rust.

[0024] like Figure 2 、 4 The inserted target plate B shown in the figure intercepts, slows down, and redirects accidentally flying projectiles. It is composed of a 50 square tube as the overall frame B3 of the inserted target plate, and a 2mm thick steel plate as the front and rear cover plates B2 of the inserted target plate. The internal material is filled with polymer fiber and damping material. After the target plate is manufactured, the surface is sprayed with plastic to prevent rust. The top of the target plate is provided with an inserted target plate lifting lug B1 for easy installation and replacement.

[0025] like Figure 2 The movable target plate 1 shown is evenly provided with target grooves made of channel steel for guiding and fixing the inserted target plate. A single movable target plate 1 is equipped with four inserted target plates B.

[0026] like Figure 1 The hydraulic lifting mechanism 2 shown in the figure consists of a hydraulic station 4 and eight hydraulic cylinders 3. The hydraulic station 4 is movable, and the hydraulic cylinders 3 are mounted at predetermined protection points on the target track via bottom fixing plates. The hydraulic station 4 provides power to the hydraulic cylinders 3. Once the anti-ricochet target plate 1 is hoisted to the upper ends of the hydraulic cylinders 3, the target plate's height is adjusted to the desired height by driving the hydraulic cylinders 3 on either side of the target plate to raise and lower it.

[0027] The hydraulic station 4 is selected to be movable and provide a pressure of up to 7 MPa, ensuring that the lifting force is greater than 2 tons after cooperating with the two hydraulic cylinders 3.

[0028] The stroke of hydraulic cylinder 3 is 1.5 meters. In order to ensure the lifting stroke, this project adopts a single-acting 3-section type. Hydraulic cylinder 3 is arranged at the preset interception point of the target track, and the bottom is fixed to the foundation by bolts.

[0029] Before conducting the high-speed projectile test on the underwater target track, the protective points of the infrastructure on both sides of the on-site water target track are arranged, and the movable target plates 1 can be arranged for the target plates at the four interception points. First, two hydraulic cylinders 3 are arranged at the preset protective points on the target track, and the bottom is fixed to the foundation by bolts; then the movable target plate 1 is lifted above the hydraulic cylinder 3 by hoisting, so that the lifting legs A5 of the movable target plate are placed on the hydraulic cylinder 3; then the output pressure and flow control of the hydraulic station 4 are adjusted to realize the lifting / lowering of the hydraulic cylinder 3; when the movable target plate 1 is lifted / lowered to the specified position, the inlet hydraulic valve of the hydraulic cylinder 3 can be closed, and the hydraulic station 4 can be moved to the next interception point to lift the movable target plate 1 at that location.

[0030] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation fall within the scope of protection of the present invention.
