Abstract
The invention relates to a method for connecting and sealing a detachable underwater cable and a sensor, which can effectively solve the problem that the sealing position of an underwater environment cable and a sensor is frequently stressed and sealed. The invention has the technical solution that a joint is added to a universal sensor and is connected with an underwater connection plug of routine use and sealed; the left end of the joint is connected with the sensor; then the right end of the joint is connected with an underwater socket through screw threads and is sealed with a seal ring on the socket; the underwater connection plug is bond up with a signal transmission cable by bicomponent glue; a sleeve is utilized to protect the combination position of the underwater socket, the signal transmission cable and the underwater plug; and an annular clearance between the sleeve and the signal transmission cable is compressed and sealed by a rubber pad, a shim and a bolt, thereby forming a structure that the connection position of the cable and the sensor is sealed into a whole. The invention has simple method, easy operation and good sealing effect, and the structure can bear great pressure change and is not easy to deform, and thereby, the method has huge economic and social benefits.
Description
One, technical field
The present invention relates to the encapsulating method that is connected of a kind of detachable submerged cable and transducer.
Two, background technology
Sealing Technology is to prevent fluid or parts or the measure of solia particle from leaking between adjacent faying face and preventing introduced contaminants (as dust and moisture etc.) intrusion machinery equipment inside, and it is widely used in all trades and professions.In industry Sealing Technologies such as Marine Sciences exploration, boats and ships naval vessels, the Sealing Technology of Aero-Space industry is all very advanced both at home and abroad at present.But to environmental work under water and the pressure amplitude that the sealing ring gap is very little, bear at the sealing position is big, the underwater sealing under this specific environment of the frequent stress deformation in sealing position, all also be not well solved at home at present.Therefore, how to realize that the underwater sealing in the specific environment is the technical problem that needs to be resolved hurrily.
Three, summary of the invention
At above-mentioned situation; for overcoming the defective of prior art; the present invention's purpose just provides the encapsulating method that is connected of a kind of detachable submerged cable and transducer; can effectively solve the problem of the frequent stressed sealing in sealing position of environment cable and transducer under water; the technical scheme of its solution is; increase a joint to general purpose transducer; attachment plug under water that itself and routine are used links to each other and seals; the method that adopts screw thread and laser welding to combine joint left end and transducer couples together; again with the right-hand member of joint by screw thread and under water socket couple together; and the sealing of the sealing ring on the dependence socket; attachment plug under water and signal-transmitting cable are in the same place by two component glue bonds; with sleeve will be under water socket and signal-transmitting cable and under water the binding site of plug protect; annular gap between sleeve and the signal-transmitting cable compresses sealing by rubber blanket and pad and bolt, constitutes the structure that cable and the transducer place of linking are sealed into one.The inventive method is simple, and is easy to operate, and good sealing effect can bear pressure variation and not yielding significantly, and its application has huge economic and social benefit.
Four, description of drawings
Accompanying drawing is a structural profile front view of the present invention.
Five, embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is elaborated.
Shown in accompanying drawing; the present invention increases a joint 1 at first for common (general) transducer; it can be linked to each other with the attachment plug under water 4 that routine is used and seal; method is; adopting screw thread and laser welding to combine joint 1 left end and transducer couples together; with the right-hand member of joint by screw thread and under water socket couple together; and 3 sealings of the sealing ring on the dependence socket; attachment plug under water 4 and signal-transmitting cable 9 are combined by the vulcanized joint 5 that bi-component glue forms; protect by the binding site of sleeve 2 socket and signal-transmitting cable and attachment plug under water under water; annular gap between sleeve and the signal-transmitting cable is sealed by rubber blanket 7 and pad 6 and hold-down bolt 8, constitutes the structure that cable and the transducer place of linking are sealed into one.
When the present invention produced connection in concrete manufacturing, its method can be provided by following embodiment:
(1) it is dark the holding wire of transducer to be filled in the about 25mm of sensor internal, fills in the transducer with the circular rubber cushion of 7mm then, and iron filings are fallen into sensor internal when avoiding tapping;
(2) on joint 1, be socket mounting hole tapping under water with the 5/16-24UNF screw tap;
(3) installing hole that processes is cleaned out, pulled out holding wire and socket wire bonds under water;
(4) smear the silicone oil resin on the sealing ring 3 with socket, tight a bolt;
(5) hold-down bolt 8, pad 6 and rubber blanket 7 are set on the cable 9 successively, again cable is removed the 50mm crust, remove the steel wire and the unnecessary heart yearn that expose out, it is stand-by to stay two lead-in wires, the about 15mm of length, attachment plug under water lead-in wire same treatment, general lead-in wire is long be no more than 40mm (≤40mm);
(6) attachment plug lead-in wire and cable tail weld under water, go between till exposing new face with Coarse Mesh Gauze polishing cable and attachment plug under water 4;
(7) the hollow pipe blended rubber cloth that latten(-tin) is rolled into internal diameter 12mm is finalized the design, attachment plug makes progress and is wrapped with adhesive tape on the lead-in wire of 30mm under water, guarantees that its diameter is 12mm, is fixed to brass tube on the adhesive tape, cable and attachment plug under water are fixed on the support, and keep with one heart;
(8) bi-component glue is fully mixed, be filled into then in the copper pipe, solidified 48 hours, form vulcanized joint 5, then auxiliary equipment such as brass tube are dismantled; Said bi-component glue is polyurethane or electron pouring sealant;
(9) sleeve 2 is set on the cable 9, then the silicone oil resin is evenly coated in attachment plug under water 4 and socket couples together;
(10) pad, rubber blanket is tightened hold-down bolt.
The inventive method is novel unique, application easy to operate, through test, adopt cable, the transducer of this inventive method encapsulation, through the indoor static pressure test of 1000 hours (about 42 days), outward appearance is good about 2MPa, insulation resistance meets the requirements, any problem does not appear, and the use of the packer permeability test surplus 200 section in engineering practice, respond well.And through be used for " ten days river power station, Shaanxi prospecting engineering ", " river mouth, Henan village key water control project prospecting engineering ", " the ditch reservoir leak stopping of Jincheng, Shanxi tin precipice with reinforce the prospecting engineering " and " the ancient virtuous key water control project in the Yellow River is reconnoitred engineering " all obtained success, reached the technique effect of sealing fully, economic and social benefit is huge.
