Abstract
The utility model discloses a marine shoe type sea chest comprising a cylindrical water inlet pipe and a water inlet grating arranged in the cylindrical water inlet pipe, wherein one side at the lower part of the cylindrical water inlet pipe, facing to the water flow direction, is provided with a boot-shaped flow guide trough connected with the cylindrical water inlet pipe as a whole; and the water inlet grating is distributed in a cavity enclosed by the cylindrical water inlet pipe and the boot-shaped flow guide trough. One side at the lower part of the cylindrical water inlet pipe, opposite to the water flow direction, is provided with a semicircular water stop ring; and the outline of the middle section of the boot-shaped flow guide trough and the horizontal base line of a ship, as well as the water inlet grating and the horizontal base line of the ship are arranged by an inclined angle. The marine shoe type sea chest can be arranged at the position of the ship bottom close to the middle part in a bilateral symmetry manner, so that the length of a seawater header pipe is shortened, the weight is lightened, the water supply effect is promoted, thus being capable of being widely applied to water supply systems of various high-speed ships.
Description
Technical field
The utility model relates to ship ' s equipment equipment, is specially a kind of boots formula sea chest peculiar to vessel that is applicable to high speed vessel seawater water supply system.
Background technology
Boats and ships are in operational process, and various device can produce heat, need constantly to replenish cooling water expansion tank and cool off.Sea chest is the maritime passage that is used for extracting seawater in the boats and ships, and seawater is drawn into seawater pipeline by sea chest by sea water pump, thereby enters the normal operation that cooling system guarantees Equipment of Vessel.In addition, the fire-fighting on the boats and ships, ballast and the sanitation system seawater that need use is also realized supply by sea chest.
Traditional sea chest peculiar to vessel is at the boats and ships port and starboard turn of the bilge case structure to be set, and by perforate on the turn of the bilge ship hull plate hull bottom is installed and is sucked grid formation sea chest.Among the shipbuilding industry standard C B/T615-1995 hull bottom is sucked the grid pattern and be divided into A type rectangular strip suction grid, the circular strip suction of Type B grid, C type circular bore suction grid and D type rectangle boring suction grid.Usually the height of left and right sides sea chest layout is different, is divided into high-order sea chest and low level sea chest.
On high speed vessel, use traditional sea chest, because sea chest is arranged on the boats and ships port and starboard turn of the bilge, the seawater house steward need be across the cabin port and starboard, the cabin area that has accounted for certain, make that usually just compact cabin is more crowded, and bigger across the seawater house steward weight of cabin port and starboard, be unfavorable for the high speed navigation of boats and ships.In addition,, can form zone of negative pressure at the sea chest place during shipping high speed navigation, easily cause the boats and ships insufficient water and produce phenomenon such as main auxiliary machine cooling water expansion tank high temperature because sea chest is at the boats and ships port and starboard turn of the bilge.
Summary of the invention
The purpose of this utility model will provide a kind of boots formula sea chest peculiar to vessel exactly, its close alow midway location that can be symmetrically arranged, and shortening seawater house steward's length and expendable weight improve water supply effect.
For achieving the above object, the boots formula sea chest peculiar to vessel that the utility model is designed, comprise the cylindrical shape coolant inlet pipe and be arranged on the interior trash rack of cylindrical shape coolant inlet pipe, described cylindrical shape coolant inlet pipe bottom is provided with the boot-shaped flame diversion trough that is connected as a single entity with it in face of a side of water (flow) direction, and described trash rack is arranged in the cavity that cylindrical shape coolant inlet pipe and boot-shaped flame diversion trough enclose.
Further, the side that water (flow) direction is carried in described cylindrical shape coolant inlet pipe bottom is provided with semicircle retaining ring, can prevent the mobile backward formation zone of negative pressure of the directly relative boats and ships of current and influence water supply effect.
Further, slanted angle α=30～60 of the middle section outline line of described boot-shaped flame diversion trough and hull horizontal base line °; Described trash rack and hull horizontal base line are and are in tilted layout its slanted angle β=5～45 °.
Advantage of the present utility model is: the middle section outline line of boot-shaped flame diversion trough and hull horizontal base line are slanted angle and arrange that water conservancy diversion reduces into water resistance effectively; The trash rack that is in tilted layout has the angle of meeting water, and can form intake pressure by the dynamic head that the relative ship's navigation of current produces and improve water supply effect; Semi-circular retaining ring can prevent the mobile backward formation zone of negative pressure of the directly relative boats and ships of current and influence water supply effect.Boots formula sea chest peculiar to vessel of the present utility model can be symmetrically arranged alow near midway location, shortens seawater house steward's length and expendable weight, improves water supply effect, can be widely used in the water supply system of all kinds of high speed vessels.
Description of drawings
Fig. 1 looks the sectional structure scheme drawing for the master of the utility model boots formula peculiar to vessel sea chest;
Fig. 2 is the A-A sectional structure scheme drawing among Fig. 1.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Boots formula sea chest peculiar to vessel shown in the figure comprises cylindrical shape coolant inlet pipe 2, and the upper end of cylindrical shape coolant inlet pipe 2 is provided with connecting flange 1, and connecting flange 1 is used to connect sea valve.Sea valve links to each other with the seawater house steward through filter, uses to the cooling system on the ship, ballast fire-fighting system and water supply system so that seawater to be provided.
Cylindrical shape coolant inlet pipe 2 lower ends are provided with the boot-shaped flame diversion trough 3 that is connected as a single entity with its welding in face of a side of water (flow) direction, and the fabricate block of cylindrical shape coolant inlet pipe 2 and boot-shaped flame diversion trough 3 is welded on the hull bottom 6.The middle section outline line of boot-shaped flame diversion trough 3 and slanted angle α=30～60 of hull horizontal base line 7 °, water conservancy diversion reduces into water resistance effectively, increases the water inlet area simultaneously.The side that water (flow) direction is carried in cylindrical shape coolant inlet pipe 2 bottoms is provided with semicircle retaining ring 5, can prevent the mobile backward formation zone of negative pressure of the directly relative boats and ships of current and influence water supply effect.
This boots formula sea chest peculiar to vessel in use, boats and ships along C shown in Figure 1 to navigation, seawater flows round about with respect to boats and ships, at the water conservancy diversion of boot last flame diversion trough 3 with under the effect of semi-circular retaining ring 5, seawater to flowing into bevelled trash rack 4, and enters the seawater water supply system by cylindrical shape coolant inlet pipe 2 along B.
During design, can calculate diameter, the size of boot last flame diversion trough 3 and the valid circulation area of trash rack 4 of determining cylindrical shape coolant inlet pipe 2 according to seawater output size; In conjunction with output size and ship speed determine boot last flame diversion trough 3 middle section outline lines and with the slanted angle α of hull horizontal base line 7, trash rack 4 and with the slanted angle β of hull horizontal base line 7 and the height of semi-circular retaining ring 5.
