Detailed Description
The technical solution of the present invention is further described below by means of the accompanying drawings and examples.
It should be noted that, unless explicitly stated or limited otherwise, the terms "connected" and "connected" in the description of the present invention are to be interpreted broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected, mechanically or electrically connected; may be directly connected or indirectly connected through an intermediate. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.
In the description of the present invention, "a plurality" means two or more unless otherwise specified; the terms "upper", "lower", "left", "right", "inner", "outer", "front", "rear", "head", "tail", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are merely for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," "third," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
As shown in fig. 1, the anti-collision device for ship propellers provided by the present invention comprises components including i-steel 1, slide 2, fixed pulley 3 and lifting rope 4, the specific structure and connection relationship of the components are:
the device is characterized in that the sliding seat 2 is installed on a stern board of a side box of a ship trunk, the I-steel 1 is clamped in a groove of the sliding seat 2, the top of the I-steel 1 is fixed with the sliding seat 2, the fixed pulley 3 is fixed on the sliding seat 2, one end of the lifting rope 4 is fixed on the ship 6, and the other end of the lifting rope 4 penetrates through the fixed pulley 3 and is connected with the tail end of the I-steel 1.
As shown in fig. 4, the section of the i-steel 1 is in a non-standard i shape, one side clamped in the groove of the sliding seat 2 is in a triangular shape, one side used for detecting rocks is in a rectangular shape, and the edges of each side of the i-steel 1 are ground into round corners so as to reduce structural damage caused by collision.
As shown in fig. 3 and 5, the upper part of the sliding seat 2 is a trapezoidal supporting seat, the middle of the side part is hollowed to form a groove suitable for the structure of the i-steel 1, the side is divided into two parts by the groove, the upper end and the lower end of each part are respectively provided with a baffle 7 for clamping the i- steel 1, 4 baffles are provided in total, and each baffle is fixed with the main body of the sliding seat 2 by 4 bolts.
The working principle and the process are as follows:
