A articulated suction grille on the bottom of a ship

Abstract

The invention discloses a hull bottom arthropod type suction grille, and belongs to the technical field of ship equipment. The hull bottom arthropod type suction grille comprises a water inlet fixingframe, and a grille board group is arranged in the water inlet fixing frame and comprises a grille head part, a grille trunk part and a grille tail part. The grille trunk part comprises a plurality ofarthropod grille boards distributed in parallel, each arthropod grille board comprises a second grille board and a pair of second connecting heads, and a connecting mechanism is connected between each pair of adjacent arthropod grille boards. The connecting mechanisms comprise fixed parts and driving connecting parts, the driving connecting parts comprise connecting rods and rotary connecting rings, the connecting rods are fixedly connected with the left ends of the second connecting heads through the rotary connecting rings, and the fixed parts comprise positioning double rods and operativepull boards. The hull bottom arthropod type suction grille can be subjected to matched adjustment according to ship seawater suction inlets under different situations by imitating the body construction of arthropods, and universality of the hull bottom suction grille is obviously improved from two aspects of size adjustment and line type adjustment.

Description

technical field [0001] The invention relates to the technical field of ship equipment, in particular to a ship bottom articulated suction grille. Background technique [0002] The grid bottom suction grille is the door frame installed on the seawater tank of the ship and used to control the opening and closing of the seawater tank. It is used to filter the sundries mixed in the seawater and prevent the sundries from blocking the fresh water heat exchanger and lubricating oil heat exchanger. , At the same time, it plays a very important role in preventing sundries from winding the cooling water pump, etc. [0003] It is customary to make the bottom suction grille in the form of a straight plate on ships or offshore platforms.

[0003] It is customary to make the bottom suction grille in the form of a straight plate on ships or offshore platforms. According to the usual practice, if the line shape of the hull plate where the bottom suction grille is located is relatively tortuous or the length-width ratio of the seabed grille is large, the bottom suction grille and There will be a large flash seam between the outer plates of the hull. According to the ship registration regulations, such a structure does not meet the requirements. It is necessary to add flash seam adjustment plates on both sides of the hull opening. Due to the narrow space of the seabed valve box, the seabed It is very difficult to add the flash seam adjustment plate in the valve box, which greatly increases the workload of the workers; at the same time, the bottom suction grille with the flash seam adjustment plate lacks aesthetics

[0004] Moreover, the grille plates of the existing bottom suction grille are all integrally formed, and then connected to the fixed frame in the form of hinges. This type of bottom suction grille can only adapt to one size of seawater suction inlet, and needs to be customized according to the size. Lack of versatility, and when the integrated grille is connected by hinges, the gap between the two sides will exceed the standard size, and debris is easy to enter from the gap
