Description
Technical field
The utility model relates to the power propulsion system of submarine, is a kind of new pump pushing-type submarine propeller specifically.
Background technology
Make a general survey of world's military affairs, the pump spray formula propelling unit mainly containing conventional propeller type propelling unit in submarine propeller field and occurred afterwards, propeller type propelling unit fltting speed is slow, noise is large, energy consumption is high, pump spray formula propelling unit overcomes the angle of rake many defects of propeller type, energy consumption is lower, noise is less, use the direction that pump spray formula propelling unit will be submarine propeller future development, but existing pump spray formula propelling unit needs the inner space taking submarine, destroy the structure and layout of Method for Inside Submarine's, pump is made to spray the angle of rake complex structure of formula, technical risk is large, cost is high, in order to solve the problem, also someone devises if the patent No. is " the submarine flank propulsive mechanism " disclosed in the Chinese patent of " ZL200920083036.5 ", avoid the structure and layout destroying Method for Inside Submarine's, improve the space availability ratio of submarine, but above-mentioned patent only address only the problem destroying Method for Inside Submarine's structure, adopt double side wings propulsion mode complex structure, technical risk is large, the high problem of cost appoints right existence, and easily there is situation about being blocked by foreign material in this propulsion mode grille guard grid.
Utility model content
The utility model provides a kind of new pump pushing-type submarine propeller according to the deficiencies in the prior art, and structure is simple, cheap, there will not be the situation that water inlet is blocked.
The technical solution of the utility model: a kind of new pump pushing-type submarine propeller, comprise the horizontal pump being arranged on submarine afterbody, it is characterized in that: the water side of horizontal pump is connected with silencer, the water inlet end of horizontal pump connects coolant inlet pipe, the water inlet of coolant inlet pipe is arranged on the both sides of submarine, water inlet is coated with filter screen, and on the outer wall of submarine, the side edge of filter screen is provided with foreign bodies removal machine.
The opening of described water inlet is diagonal-cut joint.
The angle of the diagonal-cut joint of described water inlet is 5 ° to 90 °.
Technique effect of the present utility model: structure is simple, water inlet adopts the mode of diagonal-cut joint to increase water inlet size, reduce resistance during navigation of submarine, foreign bodies removal machine can be good at disposing the foreign matter that filter screen is piled up, and effectively prevents water inlet blocked, the cooperation of horizontal pump and silencer, advance effective, noise is little, and whole propelling unit is cheap, maintenance and easy to maintenance.
Accompanying drawing explanation
Fig. 1 is the utility model schematic side view;
Fig. 2 is the utility model schematic top plan view.
Number in the figure represents respectively: 1-submarine, 2-horizontal pump, 3-silencer, 4-coolant inlet pipe, 5-water inlet, 6-filter screen, 7-foreign bodies removal machine.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further illustrated:
As depicted in figs. 1 and 2, a kind of new pump pushing-type submarine propeller, comprise the horizontal pump 2 being arranged on submarine 1 afterbody, it is characterized in that: the water side of horizontal pump 2 is connected with silencer 3, the water inlet end of horizontal pump 2 connects coolant inlet pipe 4, the water inlet 5 of coolant inlet pipe 4 is arranged on the both sides of submarine 1, and water inlet 5 is coated with filter screen 6, and on the outer wall of submarine 1, the side edge of filter screen 6 is provided with foreign bodies removal machine 7.
The opening of water inlet 5 is diagonal-cut joint.
The angle of the diagonal-cut joint of water inlet 5 is 5 ° to 90 °.
Time submarine needs to navigate by water, seawater enters in coolant inlet pipe by filter screen, starting mode of pump, water in water inlet is injected to from water side the chamber of silencer and forms a higher-pressure region by horizontal pump, high speed in higher-pressure region, High-Pressure Water is continuous, uniformly to the release below of submarine, impact marine seawater, produce huge antagonistic force, promote navigation of submarine, in navigation of submarine process, along with the quickening of the speed of a ship or plane, flow to flow rate of water flow in coolant inlet pipe also in synchronous quickening, in coolant inlet pipe, flow rate of water flow has just had initial velocity close to the submarine speed of a ship or plane and hydraulic pressure, namely be equivalent to add a boost pump when not increasing power at horizontal pump water inlet end and be pressurised into water pump water filling, thus substantially increase the work efficiency of water pump, particularly be designed to the water inlet of diagonal-cut joint, the size of adjustable intake, for water pump supercharging is provided convenience, reduce resistance during navigation of submarine, greatly reduce the energy consumption of navigation of submarine, the saving of energy consumption is that the underwater continuation of the journey of submarine provides condition, substantially prolongs the time of submarine submerge under water.
Enter foreign material to prevent water inlet and damage water pump, in water inlet, filter screen is set, filtering foreign falls by filter screen, ensure that water pump normally works, can pile up foreign matter after filter screen period of service is of a specified duration, the foreign matter of accumulation can affect the size of flooding quantity, so arrange foreign bodies removal machine on filter screen limit, remove the foreign matter that filter screen is piled up at any time, prevent filter screen by foreign matters from being blocked.
The water side joint noise reduction device of horizontal pump, when silencer can reduce navigation of submarine, the noise of water pump water spray, can play the effect of noise reduction, can also at the outer setting direction reverser of silencer, change the direction of water pump ejection High-Pressure Water, thus change the course of submarine.
A kind of new pump pushing-type submarine propeller of the present utility model, water inlet adopts the mode of diagonal-cut joint to increase water inlet size, reduce resistance during navigation of submarine, foreign bodies removal machine can be good at disposing the foreign matter that filter screen is piled up, effectively prevent water inlet blocked, the cooperation of horizontal pump and silencer, advance effective, noise is little, whole submarine propeller is energy-efficient, muting function good, cheap, be easy to the upgrading to existing old-fashioned submarine, structure is simple, maintenance and easy to maintenance.
