Abstract
The utility model relates to a water-jet type full speed active stabilizer for ships. The utility model comprises a water pump [1], a power source [2] for the water pump, an energy storage device [3], a pressure measuring device [4], a ship attitude signal device [5] and a control valve [6] which are connected through water pipe lines. The utility model actively provides a kind of resistance reverse to that the swing of the ships to the ships in a real time way with a water-jet form, and can produce a high efficient active stabilization action to the ships under the condition of different speed. The utility model has the characteristics of little space occupation in the ships, balanced running, reliable use, automatic operation, no addition out of the ships, little influence on ship body intensity, etc., and can be widely used for attitude regulation and positioning control of the ships which on the water surface or under the water.
Description
(1) technical field:
The utility model relates to a kind of ship stabilizer, is applicable to alleviate excessive the waving that above water craft produces in stormy waves, is beneficial to navigation, safety, the use of boats and ships.
(2) background technology:
Before the present utility model, boats and ships subtract the three kinds of modes that mainly contain of shaking: bilge keel, antirolling tank and stabilizer.Bilge keel is that stabilizing efficiency is limited by the passive type antirolling apparatus of increase ship rolling damping, generally can only be as the auxiliary mode of shaking that subtracts.Antirolling tank be by regulate and the control boats and ships in the water yield in two cabins that are connected, produce to subtract and shake moment, though its stabilizing efficiency is not influenced by ship speed, it is bigger that it takies the space in the cabin in, improved ship cost and cost and made initial stability of vessel decline.Stabilizer has to subtract for middle and high fast boats and ships and shakes the efficient height, takies the advantage that the cabin inner volume is little, be easy to control, but when boats and ships navigate by water under low speed, the stabilizing efficiency of stabilizer is extremely low, stabilizer was not just worked when boats and ships berthed, again because stabilizer is installed in outside the hull usually, easily by damage, and again to ship's navigation generation additional friction.
(3), summary of the invention:
The purpose of this utility model is the deficiency that overcomes the existing ship antirolling apparatus, provides a kind of stabilizing efficiency obvious, use reliably, and equilibrium operation, less to influence of ship-body, simple in structure, the full speed of a ship or plane of the boats and ships of convenient operating maintenance is antirolling apparatus initiatively.
The utility model comprises water pump [1], water pump propulsion source [2], energy storage [3], loadometer [4], ship attitude signal instrument [5] and control cock [6].It can be at any speed of a ship or plane (comprise zero speed of a ship or plane)---and under the full speed of a ship or plane situation, providing in real time and ship rolling motion direction opposite effect power, so can alleviate the rolling that boats and ships produce efficiently in stormy waves, is a kind of active mode of shaking that subtracts of best results.Again owing to outside hull, be not provided with any additional device thing, thus former ship performance is not produced additional effect, as: increase the boats and ships additional resistance or hinder the stop use of boats and ships.In addition, in the utility model when operation,, energy storage [3] has played actv. to whole line pressure and has transferred and can act on, make water pump [1] and propulsion source [2] needn't frequent starting with close, their operation is also just more steady, thereby has improved the safety and the economy of its use.Control cock arranged in pairs [6] is a bogie type dish valve, under the signal control of the seel direction that ship attitude signal instrument [5] provides, can sensitivity change the water flow jet direction effectively, and working condition is safe and reliable.Connect layout because whole apparatus system is a pipeline again, can improve the alerting ability of its layout, take available space in the less cabin, hull is caused less infringement.
If ship attitude signal instrument of the present utility model [5] is added the function that can determine the boats and ships water surface or submarine site, then the utility model can carry out the water surface of boats and ships or dynamic positioning under water or attitude adjustment.
(4), description of drawings:
Accompanying drawing 1 is initiatively antirolling apparatus system composition diagrams of the water jet full speed of a ship or plane boats and ships of the utility model
(5), the specific embodiment
The utility model is achieved in that it comprises water pump [1], water pump propulsion source [2], energy storage [3], loadometer [4], ship attitude signal instrument [5], control cock [6]; Water pump [1], energy storage [3], control cock [6] are connected by water pipeline, and energy storage [3] is parallel on the water pipeline, and the loadometer [4] that links to each other with circuit with water pump propulsion source [2] is housed; Control cock [6] is arranged in pairs, is bogie type dish valve, and is connected by control circuit with ship attitude signal instrument [5] simultaneously with water pump propulsion source [2].When boats and ships shown in Fig. 1 long and two-short dash line produce excessive waving, ship attitude signal instrument [5] (can be gathered Ship Swaying information, analyze, processing) sends signal, start water pump propulsion source [2] (available adjustable electric motivation, or also can the company of extension aboard ship on other propulsions source with diesel engine) drive water pump [1] seawater is pumped into pipeline, (can adopt bogie type dish valve by control cock [6] again, this valve arrangement is simple, use reliable, has only standard-sized sheet full cut-off two states, two is one group of interlock, open a pass for one simultaneously, hocket) be ejected into hull and produce propelling thrust outward, the water flow jet situation of two opposite senses of the every side of ship outlet, the direction of the Ship Swaying that is collected by ship attitude signal instrument [5] and the signal of size are controlled; All the time make jet water course produce the direction of application force and the direction opposite (this is realized by control cock [6]) of Ship Swaying, its size increases with the increase of seel amplitude that (this is increased the power of water pump propulsion source [2] by control, promptly realize) with the pump outlet capacity that improves water pump [1], jet water course will provide enough big damping moment to waving boats and ships in real time like this, force boats and ships to return to the situation of top-uping normally as early as possible, so can produce best active stabilizing efficiency.The energy storage [3] that is parallel on the pipeline can (can be opened and closed in the change procedure by control cock [6] and produce) when piping flow and pressure variation, stores the balanced line pressure of water energy that changes in the pipeline, makes water pump [1] smooth running.When if line pressure is excessive, loadometer [4] will send signal and stop water pump [1] operation, to ensure pipeline system safety.
Clearly, result of use of the present utility model also depends on: wave situation during according to ship dimensions and ship's navigation, pipeline system (is imported and exported shape, pipeline bore, trend, layout ...) and each equipment (performance, specification---seriation) carried out distribute design rationally.
