Abstract
The invention relates to ship propulsion devices, in particular to an improvement of a ship water jet propulsion device. The marine deflectable water jet propulsion device comprises a conduit and a propeller device fixedly mounted in the conduit, wherein the water inlet end of the conduit is arranged at the bottom of a ship; the water outlet end of the conduit is arranged at the stern part of the ship; a hollow nozzle capable of being controlled to rotate horizontally is mounted in the water outlet end of the conduit; the outer surface of the nozzle and the spherical surface of the inner wall of the conduit are glidingly contacted; a reverse thrust conduit is mounted below the conduit; the water outlet end of the reverse thrust conduit points to a ship bow ; the water inlet end of the reverse thrust conduit is connected onto the conduit between the nozzle and the propeller device; a conduit valve capable of being controlled to open and close is mounted at the water outlet end of the conduit; and a reverse thrust valve capable of being controlled to open and close is mounted on the reverse thrust conduit. The marine deflectable water jet propulsion device can change a water jet direction so as to change a ship advancing direction, and has the characteristics of high efficiency, omission of a complicated rudder gear and reduction of ship weight.
Description
Technical field:
The present invention relates to marine propulsion, relate in particular to the improvement of marine water-jet propulsion system.
Background technology:
Hydraulic efficiency jet propulsion system is a kind of of marine propulsion; possesses remarkable high-speed maneuverability; accelerate with deceleration and stopping performance aspect have the performance identical with nonuniform pitch propeller; when revolution the side force that produces of hydraulic efficiency jet propulsion system radius of turn is reduced and noise and vibration less; shallow draft; shallow water effect is little; transmission device is simple; the annex resistance is little; protective value good and daily service and the comparatively easy characteristics of maintenance; existing marine water-jet propulsion system is mainly by primary mover and driving device; propeller arrangement; conduit; rudder and the combined operation of falling rudder equipment etc. are formed; propeller arrangement is fixedly mounted in the conduit; the water inlet end of conduit places bottom of ship; the water side of conduit places the ship stern; the thrust promotion boats and ships that rely on propeller arrangement that water is released generation fast from the ship stern advance; this hydraulic efficiency jet propulsion system structure is uncomplicated; but can not change the direction of water spray to adjust the working direction of boats and ships; need and rudder gear auxiliary work together; could realize turning round of boats and ships; and the Shi Shuineng that comes about scatters and disappears big; efficient is low; can multi-aspectly spray water at present, do not need the marine water-jet propulsion system of rudder gear still rare.
Summary of the invention:
At the prior art above shortcomings, the objective of the invention is to provide a kind of deflectable hydraulic efficiency jet propulsion system peculiar to vessel, it can change water spraying direction to change the direction that boats and ships advance, and has the efficient height, save complicated rudder gear, reduce the characteristics of ship weight.
In order to solve the problems of the technologies described above, the scheme of technical solution problem of the present invention is: a kind of deflectable hydraulic efficiency jet propulsion system peculiar to vessel, comprise conduit and be fixedly mounted on the interior propeller arrangement of this conduit, the water inlet end of described conduit places bottom of ship, the water side of described conduit places the boats and ships stern, but the shower nozzle of the hollow of controlled level rotation is installed in the water side of described conduit, the inwall sphere moving contact of the outside face of this shower nozzle and described conduit, the below of described conduit is equipped with anti-pushing catheter, stem is pointed in the water side of this anti-pushing catheter, the water inlet end of this anti-pushing catheter is connected on the conduit between described shower nozzle and the described propeller arrangement, the water side of described conduit is equipped with the duct valve that can control folding, and the anti-valve that pushes away that can control folding is installed on the described anti-pushing catheter.
After adopting such scheme, 1, because but the shower nozzle of the hollow of controlled level rotation is installed in the water side of conduit, the inwall sphere moving contact of the outside face of this shower nozzle and described conduit, so can change the direction of water spray by the angle of control shower nozzle horizontal deflection, realize turning to of boats and ships, complicated rudder gear and steering wheel have been saved, again owing to utilize the deflection of shower nozzle directly to change water spraying direction, water can scatter and disappear little, the commentaries on classics distance of efficient height and deflection shower nozzle is not very big, power and the volume of the executive device of control shower nozzle deflection are also little, effectively increased the boats and ships utilization of space, reduce ship weight, thereby improve the work efficiency of marine main engine, also saved the cost of the Equipment of Vessel of appropriate section.2, because anti-pushing catheter is installed below conduit, stem is pointed in the water side of this anti-pushing catheter, the water inlet end of this anti-pushing catheter is connected with conduit between described shower nozzle and the described propeller arrangement, the water side of described conduit is equipped with the duct valve that can control folding, the anti-valve that pushes away that can control folding is installed on the described anti-pushing catheter, so open duct valve and close the anti-valve that pushes away, then current flow out at a high speed from shower nozzle, boats and ships forwards navigate by water; Closure catheter for closing valve and the anti-valve that pushes away of unlatching, then current flow out at a high speed from anti-pushing catheter, and boats and ships are moved backward.Manoevreability and the quick reaction capability of boats and ships have been improved greatly.
The control stalk that described shower nozzle is rotated is installed on the described shower nozzle.
Description of drawings:
Below in conjunction with the drawings and specific embodiments the present invention's deflectable hydraulic efficiency jet propulsion system peculiar to vessel is described in further detail.
Fig. 1 is the structural principle scheme drawing of the present invention's deflectable hydraulic efficiency jet propulsion system peculiar to vessel.
The specific embodiment:
Among Fig. 1, deflectable hydraulic efficiency jet propulsion system peculiar to vessel comprises conduit 2 and the propeller arrangement 5 that is fixedly mounted in this conduit 2, the water inlet end of conduit 2 places bottom of ship, the water side of conduit 2 places the boats and ships stern, but the shower nozzle 4 of the hollow of controlled level rotation is installed in the water side of conduit 2, the inwall sphere moving contact of the outside face of this shower nozzle 4 and conduit 2, the control stalk 3 that shower nozzle 4 is rotated is installed on the shower nozzle 4, the below of conduit 2 is equipped with anti-pushing catheter 6, stem is pointed in the water side of this anti-pushing catheter 6, and the water inlet end of this anti-pushing catheter 6 is connected with conduit 2 between shower nozzle 4 and the propeller arrangement 5.The water side of conduit 2 is equipped with the duct valve 1 that can control folding, and the anti-valve 7 that pushes away that can control folding is installed on the anti-pushing catheter 6.Open duct valve 1 and close the anti-valve 7 that pushes away, then current flow out at a high speed from shower nozzle 4, navigation that boats and ships forwards (comprise dead ahead, left front, right front); Closure catheter for closing valve 1 and the anti-valve 7 that pushes away of unlatching, then current flow out at a high speed from anti-pushing catheter 6, and boats and ships are moved backward.Boats and ships forwards navigate by water when needing to turn, and the angle of adjusting shower nozzle 4 horizontal deflections gets final product.Manoevreability and the quick reaction capability of boats and ships have been improved greatly.
