Abstract
The utility model discloses a sundries clearing device for shipping pushing water system which comprises a grid bar and a shell which is different with the usual one. The shell on which an upward disassembly opening is arranged, is connected within a water input pipe and water pushing pump. The grid bar is arranged within a water running channel in the shell through the disassembly opening on which a sealing cover is provided and above which an enclosing canister is arranged. The utility model has the following benefits: firstly, operators can open the sealing cover of the disassembly opening located in the shell of the ship body directly to take out the disassembling grid bar with no need for extra facility support such as divers so that the clearing operation is very easy; secondly, the sundries caught by the grid bar can be cleared completely and frequently so that the working efficiency of the water pushing pump can be improved; lastly, in the process of navigation, the sundries caught by the grid bar can be cleared when necessary.
Description
Technical field
The utility model relates to a kind of marine equipment, is specifically related to a kind of device for eliminating impurities of marine water-jet propulsion system.
Background technology
Marine water-jet propulsion system is used for the propelling of boats and ships, and it mainly relies on the work of water jet propulsion pump that power is provided.When boats and ships during in filthy coastal and inland river Chao Bo operation, foreign material enter water jet propulsion pump easily, thereby influence the normal operation of pump.In order to stop that foreign material enter water jet propulsion pump, need to install the device for eliminating impurities of hydro-jet propulsion system.The device for eliminating impurities of existing hydro-jet propulsion system mainly is to arrange stationary grizzly between inlet channel and hydro-jet propulsion system water inlet, stops foreign material by stationary grizzly.For keeping the unimpeded of boost pump water inlet, need in time remove the foreign material that stationary grizzly stops, need the diver to slip into the hand hole of hull bottom by water jet propulsion pump inflow point during removing and draw with hand and dig or with pressurized air or the flushing of high pressure (fire-fighting) water.So just have clear operation inconvenience, remove unclean problem, and boats and ships can't be removed in the boat way.
Summary of the invention
Technical problem to be solved in the utility model is the device for eliminating impurities that a kind of marine water-jet propulsion system is provided at the deficiency of above-mentioned prior art existence, and it can not only effectively stop foreign material, and it is convenient clean to remove foreign material.
The utility model is that the technical scheme that technical matters adopted of the above-mentioned proposition of solution is: comprise grid 1, different is, also include housing 6, described housing is connected between inlet channel 5 and the water jet propulsion pump 7, housing 6 is provided with the dismounting mouth that opening makes progress, described grid is contained in the flowing water passage of housing by the dismounting mouth, on the dismounting mouth of described housing seal cover cap 2 is housed, and a dismounting mouthful top is installed on encloses tube 3.
Press such scheme, a plurality of grids or multiple-structure grid can be housed in the described housing.
Press such scheme, be provided with slot at the dismounting mouth place of housing, the frame both sides of grid 1 and slot phase configuration.
Press such scheme, describedly enclose the drinking water that tube 3 upper surface is higher than ship, when drinking water was dark, the described tube upper end of enclosing can install one again additional and connects high section and enclose tube 4.
The beneficial effects of the utility model are: 1) the operating personal seal cover cap that only needs to open in hull in the housing dismounting mouthful just can take out above-mentioned removable grid, does not need the diver to wait the support of other facility, and clear operation is very convenient; 2) can remove the foreign material that stop on the grid neatly, and often remove, help to improve the work efficiency of water jet propulsion pump; 3) can in the boat way, remove by the foreign material of plaid matching grid resistance retaining in case of necessity.
Description of drawings
Fig. 1 is the positive sectional structure chart of an embodiment of the utility model.
Fig. 2 is the birds-eye view of Fig. 1.
Fig. 3 implements the scheme drawing of running condition for the utility model.
The specific embodiment
Further specify embodiment of the present utility model below in conjunction with accompanying drawing.
Include housing 6, housing is connected between water jet propulsion pump 7 and the inlet channel 5, form a leak free flowing water passage, on housing 6, offer the trapezoidal dismounting mouth that opening makes progress, dismounting mouthful both sides are provided with slot from top to bottom, the slot that the dismounting mouth is inserted in the frame both sides of grid 1 is contained in the housing 6, traverses in the flowing water passage, stops that foreign material enter water jet propulsion pump 7.Grid 1 has curved surfaces, has steel bar on it and intersects formed diamond-shaped meshes, and arc pushes up towards inlet channel 5 directions, can make the water speed that enters boost pump more steady, and grid 1 can be by thin gradually close multilayer grid, make stop more effective.Dispose seal cover cap 2 on the dismounting mouth of housing 6, in order to keep watertight.For preventing that seawater overflows to cabin when dismounting seal cover cap 2 and the grid 6, the dismounting mouth top of described housing 1 is provided with encloses tube 3, a lower end and a housing dismounting mouthful sealing of enclosing tube link, the upper surface height that encloses tube is higher than the drinking water of ship, can install by water valve 8 in lower end one side of enclosing tube, by water valve with enclose tube inner chamber and be connected, a draining that is used to enclose tin; When drinking water was dark, described enclosing also can be installed one again additional and connect high section and enclose tube 4 above the tube.
