Description

Water jet carrier

The utility model relates to a kind of water jet carrier.

Common carrier, especially for the medium and small carrier of river navigation, its common type of drive all is the form that is rearward pushed away water by the mechanisms such as impeller that are located at quarter of a ship, it is pushed rearward water and all comes from around the impeller.And ship in motion, and the upstream face in ship side the place ahead will inevitably run into the resistance of water, all is changing modes such as ship side angle and radian reducing resistance as far as possible at present, and fails resistance or part resistance are rationally utilized.

The purpose of this utility model is to provide a kind of water jet carrier, makes it can make full use of application force between hull and the water, to reach the purpose of saving the energy and improving ship's speed.

The water jet carrier of the utility model left-right symmetric position below hull respectively is provided with a water space that is isolated with the ship storehouse, and its place ahead is respectively through preceding inlet channel and following inlet channel and be opened near the preceding water inlet the bow portion ship side upstream face waterline and be opened on the following water inlet UNICOM of boat bottom; Its rear all be opened on stern below and wherein be provided with the water jet standpipe UNICOM that pushes away water impeller that connects with axle drive shaft.Be provided with the structure of blocking at preceding water inlet and following water inlet.The resistance of water that ship is rightabout relative motion and forms thus between ship and the water in motion to navigating, when upstream face place, the utility model said structure ship side the place ahead has offered water inlet, just in time can utilize, the water that makes part should form resistance enters from preceding water inlet smoothly naturally, behind water space, be pushed water impeller blowing water pipe and spray release backward, change into ahead power into hull.Equally, utilize hull gravity to press down the contradiction of the buoyancy that hull is made progress with water, the following water inlet that is positioned at the boat bottom position in the utility model said structure also can make the part water at hull bottom place successfully enter naturally, warp inlet channel down is compiled in water space equally, spray release backward through pushing away water impeller blowing water pipe again, form the onward impulse of hull.Therefore, spray backward and push away and the water of hull ahead power is provided by pushing away water impeller, not only need not to use additional energy source, also can not form adverse effects such as unnecessary extra turbulent flow, whirlpool, and can reduce and dissolve the resistance that part is advanced, help energy savings and improve ship's speed.Be to increase the water spray propelling thrust, the sectional area that can make the outlet of water jet standpipe water spray suitably effectively pushes away water area less than what push away water impeller.In preceding water inlet and following water inlet, enter for preventing foreign material such as floating debris, the necessary structure of blocking is set.Test shows that the structure of setting up of blocking is too fine and closely woven might not be favourable, easily is closed or partially enclosed live for fibrous or sheet foreign material hide.The structure of blocking is arranged to the crossed grid net form formula that water direction side into is the cutting edge shape can prevents more effectively that this phenomenon from taking place.

For further reducing the ship resistance, the bow at water inlet place bottom is in same baseplane substantially with the hull bottom before can making, and the bow bottom is in the state that is submerged under water when making foot.Can prevent like this that bow bottom from upwarping too highly makes the bow bottom that it upwarps when navigating be higher than the water surface and be subjected to excessive wave making resistance.

Below the utility model is described in further detail with example shown in the drawings, but the scope of the utility model foregoing is not limited only to down example.

Fig. 1 structural representation of the present utility model.

The A-A figure of Fig. 2 Fig. 1.

The B-B figure of Fig. 3 Fig. 1.

As figure, the bow portion ship side 2 and the mid-ship ship side 15 of these water jet carrier both sides are linear pattern, and angle is 160 °～165 ° therebetween, and the angle of bow portion both sides ship side 2 at the bow place is 25 °～30 °.Respectively be provided with a water space 9 that is isolated with the ship storehouse in the left-right symmetric mode below the hull postmedian, its place ahead links with preceding water inlet 3 that is opened on ship side 2 upstream face waterline vicinity and the following water inlet 6 that is opened on boat bottom through preceding inlet channel 5 and following inlet channel 8 respectively; Its rear all be opened on stern below and wherein be provided with the water jet standpipe that pushes away water impeller 11 12 UNICOMs that connect with axle drive shaft 10, the sectional area of this water jet standpipe water spray outlet should be slightly less than push away water impeller effectively push away water area, and be provided with the shear constitution 16 that matches with it in the water inlet side's side that pushes away water impeller 11, with the adverse effect of avoiding biologies such as small fish and shrimp that impeller is produced.Be provided with the structure 4,7 of blocking of cross graticule mesh pattern at preceding water inlet 3 and following water inlet 6 places, descend also can establish again in the inlet channel one deck cross lattice pattern structure of blocking in case of necessity.The block water inlet direction side of structure 4,7 of this cross graticule mesh is blade shape, as shown in Figure 3.The bottom 13 of the bow 1 at water inlet 3 places is in same baseplane substantially with hull bottom 14 before the hull, makes ship be in the state that is submerged under water in bow bottom 13 in motion.Prove that through small scale experiment the resistance that the hull of said structure advances in the river is compared and can obviously be reduced with the ship of present traditional form, energy resource consumption reduces, and moving velocity improves.
