Title: PROPELLER FOR INCREASING PENETRATION DEPTH OF GRAVITY INSTALLED PLATE ANCHOR AND METHOD THEREOF
Abstract:
A propeller (2) for increasing a penetration depth of a gravity installed plate anchor, comprising a cylindrical middle shaft (2a). The cylindrical middle shaft (2a) is designed in a streamline form, the front end thereof is ellipsoidal, and the tail thereof gradually contracts. The tail of the cylindrical middle shaft (2a) is provided with three tail wings (2b) and is connected to the tail of the propeller (2) by means of a slot. The front end of the cylindrical middle shaft (2a) is provided with a connecting groove (2c) to connect a gravity installed plate anchor (1). The propeller (2) is detachably installed at the tail of the gravity installed plate anchor (1), and can increase the falling speed of the gravity installed plate anchor (1) in water and enhance the directional stability of the gravity installed plate anchor (1). The propeller (2) can be recycled and reused, thereby reducing total project costs.
