Detailed description of the invention
Develop simultaneously embodiment below in conjunction with the accompanying drawings, describes the present invention.
The present invention provides a kind of watertight joint sealing of vibration noise acquisition system in floating test, this watertight joint sealing can provide, for vibration noise acquisition instrument, the watertight space closed, signal transmission and power interface are provided simultaneously, make vibration noise acquisition instrument be capable of on the bank and monitor and supplementary power.
The concrete structure of this watertight joint sealing is as it is shown in figure 1, include: casing, cable 3 and photographic head 4.Wherein vibration noise acquisition instrument and power supply are arranged on box house, and casing provides the working environment of watertight for vibration noise acquisition instrument, it is to avoid vibration noise acquisition instrument and power supply are immersed in water.Casing is closing lid structure, is made up of joint sealing base 1 and joint sealing lid 2, is tightly connected by bolt, packing ring, nut and liner between joint sealing base 1 and joint sealing lid 2.Upper surface at joint sealing lid 2 is machined with the installing hole of the cup-shaped tube coupling of cable 5, is tightly connected between the cup-shaped tube coupling of cable 5 and joint sealing lid 2, and cable 3 passes joint sealing lid 2 through the cup-shaped tube coupling of cable 5.Being provided with light in casing and illuminate the photographic head 4 of function, for monitoring the state of its internal vibration Noise Acquisition instrument, photographic head 4 is powered by internal electric source.
Cable 3 is integrated with video signal transmission wire, netting twine, power cable and sensor signal transmission line.According to the function of heart yearn, cable internal core is divided into sensor signal transmission heart yearn, network cable transmission heart yearn, video signal transmission heart yearn and electric wire heart yearn.Cut cable at box house: sensor signal transmission heart yearn is connected with the input port of acquisition instrument, network cable transmission heart yearn is connected with the netting twine delivery outlet of acquisition instrument, video signal transmission heart yearn is connected with photographic head 4, and electric wire heart yearn is connected with power source charges end electric wire.Cut cable outside casing: sensor signal transmission heart yearn is connected with outside vibrating sensor or hydrophone by sensor signal transmission line watertight connector, thus casing external sensor signal is transported to the Acquisition Instrument input of box house；Network cable transmission heart yearn is connected with outside netting twine watertight connector, it is provided that the interface that during intertrial interval, system is connected with external computer, in order to determine that sensor signal is the most normal, and can realize the storing card data unloading of acquisition instrument, it is to avoid insufficient memory.Video signal transmission heart yearn is connected with outside photographic head data wire watertight connector, monitors for the intertrial interval phase and confirms the sealed environment within joint sealing.Electric wire heart yearn is connected with external power cord watertight connector, it is provided that during intertrial interval, system is connected the interface of charging with external power source, it is to avoid carrying out smoothly of Acquisition Instrument electricity shortage impact test.
Joint sealing base 2 is reserved with installing hole, for being fixed with test model by watertight joint sealing.For improving the resistance to corrosion of watertight joint sealing, plate epoxy zinc-enriched antirust paint in the outside exposed structure of watertight joint sealing.
The concrete installation step of this watertight joint sealing is:
(1) acquisition instrument and power supply are arranged on joint sealing base；
(2) photographic head is arranged on joint sealing lid；
(3) outside casing, cable is connected with video signal transmission wire watertight connector, netting twine watertight connector, power line watertight connector and sensor signal transmission line watertight connector respectively by corresponding heart yearn；
(4) by cable through joint sealing lid, its heart yearn is connected with the Acquisition Instrument of box house, power supply, heart yearn that photographic head is corresponding respectively, and cable is carried out water tight enclosure；
(5) the cup-shaped tube coupling of cable, clamp nut, packing washer, airtight and watertight padding are installed, by cable and joint sealing lid fixing seal；
(6) joint sealing lid is arranged on joint sealing base, by bolt, packing ring, nut, liner, by case lid with joint sealing base fixing seal.
The using method of this watertight joint sealing is:
First, by video signal transmission wire, netting twine monitoring box body internal medium and Acquisition Instrument each channel data state, confirm errorless after, watertight joint sealing is fixed on and need to carry out inside the model of underwater test.Underwater test often completes once to float after testing, and sees power supply surplus by video signal transmission wire, netting twine casing monitoring internal medium, Acquisition Instrument each channel data state product.By camera head monitor box house ambient condition, once water inlet immediately treats after finding.By cable interface, acquisition system condition monitoring can be realized, and can the data of continual unloading acquisition system storage card, it is to avoid insufficient space causes the test data of front batch to be capped.When box house power supply surplus is few, suspend test of floating, connect external power source plug by external power cord watertight connector, joint sealing internal electric source is charged.
In sum, these are only presently preferred embodiments of the present invention, be not intended to limit protection scope of the present invention.All within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
