Description
Technical Field
[0001] The utility model relates to the technical field of ship building, in particular to a sand retaining plate and an open cargo hold sewage well on which the sand retaining plate is installed. Background Art
[0002] The sewage well of the open cargo hold of a 950TEU container ship is divided into a sedimentation tank and a suction tank. A partition is set between the sedimentation tank and the suction tank. To facilitate the entry and exit of the crew, a manhole is opened on the partition. However, the aperture of this manhole is too large, and the mud and sand in the suction tank easily flow into the sedimentation tank from the manhole. Therefore, a mud guard with a filter hole needs to be installed at the manhole to block the mud and sand. However, the current sewage well construction plan cannot achieve the goal of firmly fixing the sand guard on one side of the manhole and easily disassembling it, making the subsequent maintenance very inconvenient.

The horizontal limit plate is symmetrically arranged on both sides of the sand barrier plate. The opening directions of the limit grooves of the two horizontal limit plates are relatively arranged. The two sides of the sand barrier plate are plugged into the limit grooves of the horizontal limit plate. The vertical limit plate is arranged below the sand barrier plate. The opening direction of the limit groove of the vertical limit plate is vertically upward. The bottom of the sand barrier plate is plugged into the limit groove of the vertical limit plate. The bottom surface of the top plate is overlapped and fixed with the top surface of the horizontal limit plate. U-shaped grooves matching the horizontal limit plates are opened on both sides of the sand barrier plate.

[0008] Preferably, a gap is set between the bottom end of the sand retaining plate and the inner wall of the limiting groove of the vertical limiting plate, and the spacing between the bottom end of the sand retaining plate and the inner wall of the limiting groove is 5 mm.
[0009] Preferably, a sewage manhole cover is provided above the sedimentation tank.
[0010] Preferably, a drain hole is provided at the bottom of the partition, and a drain plug is provided in the drain hole.
[0011] Compared with the prior art, the utility model has the following advantages:
[0012] 1. Through the cooperation of the horizontal limit plate and the vertical limit plate, the two sides and the bottom of the sand retaining plate are limited in the limit groove, ensuring that the sand retaining plate can be firmly fixed on one side of the manhole, and the silt in the suction chamber is limitedly blocked from flowing into the sedimentation chamber.
[0013] 2. Through the U-shaped grooves on both sides of the sand retaining plate, move the sand retaining plate along the horizontal limit plate toward the partition until both sides of the sand retaining plate are inserted into the limit grooves of the horizontal limit plate, and then use the sand retaining plate's own gravity to fall, so that the top plate of the sand retaining plate is overlapped and fixed with the horizontal limit plate. This structure makes it easier to disassemble the sand retaining plate and simplifies the maintenance of the sewage well in the later stage. BRIEF DESCRIPTION OF THE DRAWINGS
