Caisson type deck drainage pipe

Abstract

The caisson type deck drainage pipe comprises a grid, a clamping sleeve, a base plate, a fixing bolt, a caisson coaming, a caisson bottom plate, an upper end sleeve, a drainage pipe body, a deck and awater inlet. By means of the caisson form, the distance between the opening and the broadside is reduced, no dead corner is left, a certain space is reserved in the caisson, the deck ponding phenomenon can be effectively prevented, and the phenomenon that bow rainwater does not enter the bow drainage pipe and flows to the stern is eradicated. The installation mode of the grid is changed, so thatrainwater can directly flow into the caisson and is not hindered, the grid is fixed through four corners, the gridcannot fluctuate under the condition of violent shaking, and due to the fact that thegrid is fixed through the butterfly nuts, operation is convenient.

Description

technical field [0001] The invention relates to the field of ship drainage equipment, in particular to a caisson-type deck drainage pipe. Background technique [0002] Ship drainage system is not only closely related to life, but also related to ship safety. However, the drainage on the deck is not smooth. When there is a large amount of accumulated water, the crew will have difficulty walking, and if they are careful, they will trip over the protrusions in the accumulated water. In the case of strong winds and waves, it is very likely that they will fall into the water after falling. , When the drainage is not smooth, the weight of the ship will increase, which will affect the performance of the ship. It can be seen that the drainage system of the ship is not only closely related to life, but also related to the safety of the crew and the ship. The number, location and pipe diameter of deck drains should be determined according to the size of the deck area and the directio...

Problems solved by technology

However, due to factors such as on-site construction and hull structure, the deck drain will be a certain distance away from the side shell, and the deck surface will have a certain inclination angle from the midship to the side, forming a dead angle, so that the drain and the side shell In this distance, accumulated water is formed, which is not easy to discharge, and most ships still have a stern tilt phenomenon, so that the water at the bow will flow to the stern through this space, increasing the drainage pressure of the stern drain. When it is too large, there will be a phenomenon that the stern drain cannot be drained expressly, and a large amount of water will accumulate

In addition, the grid installation form currently used is all close to the deck surface, which will cause the water flow to be blocked by the grid and cannot flow into the drain pipe smoothly, which will greatly reduce the drainage effect; and the current grid is easy to open. Only install two semi-circular pipe short joints on one side of the round steel for fixing. This design is simple, but when encountering strong winds and waves, the other end of the grille will also rise and fall, constantly hitting the deck surface, damaging the deck surface paint
