Description
Technical field
The utility model relates to a kind of constant frequency and constant voltage hydraulic electricity generation unit, and it generates electricity applicable to boats and ships or other occasion.
Background technique
At present the required electric energy of ship's navigation all is by using the act as a fuel generator special group of burning of light oil to provide basically, and the construction cost of boats and ships and user cost are all higher.And if use ship power main frame directly drives generator for electricity generation, then on the one hand because the ship power main frame receives the influence of working environment, there is the problem of serious shakiness in its rotating speed, causes generator speed unstable easily, the unstable phenomenon of output electric energy; On the other hand, mechanical loss is bigger, and the mounting point of generator also can be restricted.
Summary of the invention
In order to solve in the existing technology owing to the fixed generator speed unstable problem that causes of original PTO rotary speed unstabilization; The utility model provides a kind of constant frequency and constant voltage hydraulic electricity generation unit; Its hydraulic pressure loop control loop and tachogenerator and intelligence controlling device through forming by oil pump, hydraulic energy storage device, ratio electrical adjustment valve etc.; Can change the unsettled output speed of original power output unit into supply the generator smooth working to use stabilized (steady-state) speed, thereby make generator produce the electric energy of constant frequency, constant voltage.
The utility model technological scheme is to constitute like this; A kind of constant frequency and constant voltage hydraulic electricity generation unit; It comprises PTO, transmitting assemblies and generator, it is characterized in that: it also comprise by oil pump, one-way valve, hydraulic energy storage device, ratio electrical adjustment valve, oil hydraulic motor and oil sump tank connect to form successively and end to end hydraulic pressure loop control loop, be located at the tachogenerator on the alternator shaft and be connected in tachogenerator and the control end of ratio electrical adjustment valve between intelligence controlling device; Said PTO is connected driving through transmitting assemblies with oil pump, said oil hydraulic motor is connected driving with generator.
The further improvement of the utility model technique scheme is: said PTO is the ship power main frame.
Said transmitting assemblies comprise be connected first belt pulley that drives with the front end output shaft of ship power main frame, be connected second belt pulley of driving with oil pump and be connected in first belt pulley and second belt pulley between feed belt, the tail end output shaft drive propulsion device of ship power main frame.
The utility model working principle is explained as follows: drive first belt pulley through the front end output shaft behind the ship power main engine starting and rotate; Adjust rotating speed and drive oil pump work through first belt pulley, feed belt and second belt pulley, during oil pump work, hydraulic oil is given the continuous fuel feeding of hydraulic pressure accumulator through one-way valve; The pressure oil that hydraulic energy storage device is constantly collected passing ratio electrical adjustment valve is again carried level and smooth pressure oil to oil hydraulic motor; Oil hydraulic motor is rotated stably, drive generator rotation then and generate electricity, simultaneously; The oil of oil motor output is got back to oil sump tank, once more the oil feed pump fuel feeding.When generator loading changes; The rotating shaft rotating speed of generator is also corresponding to change, and tachogenerator is given intelligence controlling device with the data transfer that collects after detecting the rotating shaft change in rotational speed of generator, and real-time rotating speed and rated speed that intelligence controlling device will collect compare analysis; And then control ratio electron pressure valve regulation output flow and pressure; Make oil hydraulic motor output speed and torsion on request, thereby the rotating speed of adjustment generator is worked generator stably.Because the energy storage effect of hydraulic energy storage device, the speed change of ship power main frame and reverse can not exert an influence to generator, thereby the electric energy that obtains constant frequency and constant voltage is supplied with the ship's navigation use.Certainly, said PTO also can adopt other power source, and through the described constant frequency and constant voltage hydraulic electricity generation of the utility model unit, the electric energy that produces constant frequency, constant voltage supplies miscellaneous equipment to use.
Compared to prior art, the utlity model has following advantage:
(1) hydraulic pressure loop control loop and tachogenerator and the intelligence controlling device of the utility model through forming by oil pump, hydraulic energy storage device, ratio electrical adjustment valve etc.; Can change the unsettled output speed of original power output unit into supply the generator smooth working to use stabilized (steady-state) speed, thereby make generator produce the electric energy of constant frequency, constant voltage.
(2) surplus of the ship power main frame of the utility model combusting heavy oil capable of using is generated electricity as power source; Because the energy storage effect of hydraulic energy storage device; And the control circuit of being made up of tachogenerator, intelligence controlling device and ratio electrical adjustment valve makes the speed change of ship power main frame can not exert an influence to generator with reversing to the real-time regulated effect of generator speed, and the electric energy of guaranteeing to obtain constant frequency and constant voltage is supplied with ship's navigation and used; Realized that boats and ships are when navigation; Do not use the generator special group, and can guarantee that boats and ships obtain the purpose of the required electric energy of ship's navigation stably when navigation, reduce shipbuilding input cost and user cost greatly; Both improve economic benefit, improved energy transformation ratio again.
(3) the utility model can use with generator special group parallel operation on the ship, strengthens the supply of electric energy.
(4) installation of the described constant frequency and constant voltage hydraulic electricity generation of the utility model unit does not receive the restriction of position, can settle everywhere, helps rationally arranging of boats and ships spatial structure.
(5) the described constant frequency and constant voltage hydraulic electricity generation of the utility model unit mechanical loss when work is little.
(6) the described constant frequency and constant voltage hydraulic electricity generation of the utility model unit does not increase noise in use, and has the effect of energy-saving and emission-reduction.
