Along with boats and ships are to maximization, high speed and automation direction development, the rapidity, high benefit, economy etc. of boats and ships, become the important indicator of shipbuilding.As calculating the important means of conversion efficiency, shaft power on-line measuring device peculiar to vessel has become the major parameter that shipyard and shipowner check and accept new shipbuilding oceangoing ship.By the measurement to shaft power under the different operating mode of main frame, can understand and check match condition between hull-main frame-thruster three, also can make diagnosis to obsolete vessel ship-machine-oar duty and fault simultaneously.Ship Axle power is one of important parameter characterizing hull and main power plant performance state.By monitoring parameters such as shaft power, and taking corresponding maintenance measure in time according to monitoring information, effectively can improve the dynamic property on naval vessel, economy and security.
At present, the metering system be most widely used is resistance strain plate and steel chord type.But resistance strain plate is easily subject to the impact of the degree of uniformity of temperature, humidity and bearing material therefor and reduces the accuracy of measurement, and the accuracy that the quality influence that steel chord type also can be subject to bearing material is measured.Meanwhile, the physical characteristics that these two kinds of metering systems also can be subject to foil gauge and string wire changes in time and affects measurement.
Summary of the invention
The utility model, for overcoming the deficiencies in the prior art, provides one and is convenient to safeguard and expand, and have the system of self-correcting function.
For achieving the above object, design a kind of Axis Power Measurement System peculiar to vessel, comprise axle peculiar to vessel, left end survey sensor, right-hand member survey sensor, left end coding collar, right-hand member coding collar, calibration code device, signal processor, signal receiver, it is characterized in that: the two ends, left and right of described axle peculiar to vessel are arranged with left end coding collar and right-hand member coding collar respectively, described left end coding collar is provided with left end survey sensor, described right-hand member coding collar is provided with right-hand member survey sensor, the axle peculiar to vessel be positioned on the left of left end coding collar is provided with calibration code device, described calibration code device, left end survey sensor and right-hand member survey sensor are connected the signal input part of terminal box respectively by communication cable, the signal output part of described terminal box passes through the signal input part of cable connection signal receiver, the signal input part of the signal output part connection signal processor of described signal receiver, described signal processor connects display.
Described left end coding collar is annular and surface is evenly equipped with some banded holes, and described right-hand member coding collar is annular and surface is evenly equipped with another banded hole of equal number.
Described display, between signal processor and signal receiver by dual-redundant CAN bus be connected.
Compared with the existing technology, when engine speed is lower than certain tachometer value, calibration code device can impel main frame automatically to adjust rotating speed to meet the requirement of shaft power measurements peculiar to vessel to the utility model; Structure is simple, is convenient to safeguard and expand.
Accompanying drawing explanation
Fig. 1 is the utility model Axis Power Measurement System schematic diagram peculiar to vessel.
See Fig. 1, wherein, 1 is display, and 2 is signal processors, and 3 is signal receivers, and 4 is terminal boxes, and 5 is left end survey sensors, and 6 is right-hand member survey sensors, and 7 is left end coding collars, and 8 is right-hand member coding collars, and 9 is calibration code devices, and 10 is axles peculiar to vessel.
Embodiment
With reference to the accompanying drawings the utility model is described further below.
As shown in Figure 1, the two ends, left and right of described axle peculiar to vessel 10 are arranged with left end coding collar 7 and right-hand member coding collar 8 respectively, described left end coding collar 7 is provided with left end survey sensor 5, described right-hand member coding collar 8 is provided with right-hand member survey sensor 6, the axle peculiar to vessel 10 be positioned on the left of left end coding collar 7 is provided with calibration code device 9, described calibration code device 9, left end survey sensor 5 and right-hand member survey sensor 6 are connected the signal input part of terminal box 4 respectively by communication cable, the signal output part of described terminal box 4 passes through the signal input part of cable connection signal receiver 3, the signal input part of the signal output part connection signal processor 2 of described signal receiver 3, described signal processor 2 connects display 1.
Described left end coding collar 7 is in annular and surface is evenly equipped with some banded holes, and described right-hand member coding collar 8 is in annular and surface is evenly equipped with another banded hole of equal number.
Described display 1, between signal processor 2 and signal receiver 3 by dual-redundant CAN bus be connected.
When the utility model uses, at the correct position of axle 10 rear and front end peculiar to vessel, left end coding collar 7 and right-hand member coding collar 8 are installed respectively, installation calibrating scrambler 9 near left end coding collar 7, installs left end survey sensor 5 and right-hand member survey sensor 6 respectively in the below of left end coding collar 7 and right-hand member coding collar 8.When hull is in anchored condition, utilize turning engine to make axle 10 low-speed running peculiar to vessel, the relative position between left end coding collar 7 and right-hand member coding collar 8 is as 0 of system.According to the size of axle 10 peculiar to vessel and material and the distance between left end coding collar 7 and right-hand member coding collar 8, calculate the moment of inertia of split bearing between left end coding collar 7 and right-hand member coding collar 8.System can according to this moment of inertia and rotating speed and between left end coding collar 7 and back-end code ring 8 side-play amount of relative position calculate main frame real power.
Left end survey sensor 5 and right-hand member survey sensor 6 can measure banded hole on coding collar whether by the plane at sensor contact place.Signal can be delivered to multiple display 1 by signal processor 2.Calibration code device 9 can provide the rotation of axle 10 peculiar to vessel more accurately to be calculated, to reach the effect of elevator system precision.
