Embodiment Construction

[0032] In order to better understand the technical solution of the present invention, the implementation steps of the present invention will be further described below in conjunction with the accompanying drawings.

[0033] Such as figure 1 As shown, the specific implementation method is to gently peel off the Kevlar layer 4 to a certain length, wrap the Kevlar layer 4 on the tapered cylinder 7 that locks the Kevlar, and tighten it so that it is embedded in the load-bearing head Inside the shell 16. Fix the oil-filled towline pressure-resistant sheath 3 on the upper sealing cover 9 of the sealed oil tank 10, fix and lock it with a locking screw filled with solid superglue 8, and secure the towline oil-filled pressure-resistant sheath 3 It is fixed on the upper sealing cover 9 of the oil-filled cabin 10. The optical fiber and the power line of the trailing cable are welded on the photoelectric hybrid watertight connector 11 to complete the switching of the photoelectric signa...

Abstract

The invention relates to a bearing head of an underwater sonar electronic system for connecting a trailing cable. The trailing cable comprises the following parts from inside out: optical fibers and a cable (1), a pressure-proof sheath (3), a Kevlar layer (4) and an outer sheath (5), wherein the trailing cable is filled with oil; the bearing head comprises an upper tapered cylinder (7) and a lower oil-filled sealed cabin (10), and the tapered cylinder (7) is used for locking the Kevlar layer (4) of the trailing cable; the oil-filled sealed cabin (10) is communicated with an oil charge oil circuit (2) in the trailing cable, the optical fibers and the cable (1) go out from the oil-filled sealed cabin (10) and are welded in a watertight plug-in component on the bearing head shell (16); the bearing head shell (16) is provided with an oil nozzle (12), and the oil nozzle (12) is communicated with the oil of a underwater sonar electronic device through a pressure-proof rubber tube (14), thus the communication of the oil charge oil way (2) and external devices in the trailing cable with mixing oil charge and photoelectricity is realized.

Description

technical field [0001] The invention belongs to the technical field of deep sea detection, in particular to a bearing head for connecting a tow cable and an underwater sonar electronic system. Background technique [0002] Underwater large-depth towed sonar relies on towed cables for towed navigation. In order to improve the pressure resistance performance of the underwater large-depth sonar electronic system, the interior of the sonar array and other equipment needs to be filled with oil to balance the internal and external pressure of the sonar cavity, so that the equipment can work at various depths underwater. At the same time, it is designed to be filled with oil, which can not only balance the pressure on the inner and outer surfaces of the cable sheath, ensure that the deformation of the cable is small when the cable is at any depth, but also ensure a good shielding effect and provide oil for the sonar electronic system below. compensate. [0003] The connection bet...
