Description

Sheath cutter for towed linear array

Technical Field

The invention belongs to the technical field of sheath cutting, and particularly relates to a sheath cutter for a towed line array.

Background

Besides a supporting framework, a lead, a strong rope and electronic components, the interior of the towing line array (hereinafter referred to as towing line array) is filled with a large amount of light paraffin oil, silicone oil or solid glue in order to ensure the zero buoyancy requirement. The devices are mainly packaged through the PU sheath, and the sheath and the connector are tightly pressed through the pressing ring at the connector, so that the watertight effect of the whole towed linear array is realized.

Before the sheath is penetrated, the sheath is generally intercepted according to the length of the array and a certain margin, so that the fault tolerance rate is improved. Therefore, after the operation of the compression ring is finished, the sheath tends to be more than one piece. In order to ensure the normal use of the trailing line array, the extra sheaths need to be cut off.

When operating, an operator often cuts off the sheath along the edge of the pressure ring by using an art designing knife, but the operation process has the following defects: 1. The sheath can not be cut neatly, which affects the assembly of the subsequent matching ring; 2. the clamping ring and the connector shell can be damaged when the sheath is cut by the art designing knife; 3. the hand of an operator is easily cut in the cutting process of the sheath, and potential safety hazards exist.

Disclosure of Invention

The invention provides a sheath cutter for a towed line array, which aims to overcome the defects of the prior art.

In order to achieve the purpose, the invention adopts the following technical scheme: a sheath cutter for a towed linear array comprises a shell and a cutting assembly arranged on the shell; the cutting assembly comprises a cutter holder arranged on the shell, an extrusion groove arranged at the bottom of the cutter holder, and a cutter component matched with the cutter holder.

Furthermore, cutter part is including locating the compressing tightly piece of blade holder tip, with compress tightly the cutting piece that the piece is connected, compress tightly the piece and can drive the cutting piece and reciprocate in the blade holder bottom.

Further, the cutting piece is a blade, and the bottom of the blade is matched with the extrusion groove.

Furthermore, a thread groove is formed in the tool apron, and the pressing piece is a pressing screw.

Furthermore, the tool apron is also provided with a limiting piece for limiting the position of the cutting piece.

Furthermore, a limiting hole matched with the limiting piece is formed in the cutting piece; the limiting part is a limiting screw in threaded fit with the tool apron.

Further, the shell is divided into an upper shell and a lower shell, and a positioning piece matched with the upper shell is arranged on the lower shell; the upper shell and the lower shell are connected through a fixing part.

Furthermore, a positioning hole is formed in the lower shell; the positioning piece is a positioning column which can be inserted into the positioning hole so that the relative position of the upper shell and the lower shell is fixed.

Further, the fixing component is a movable joint bolt and a nut.

Further, the swing bolt can be inserted into the positioning post.

In conclusion, the length of the cutting piece moving out of the bottom of the cutter holder is adjusted by moving the pressing piece, so that the connector is prevented from being damaged while the sheath is cut; the rotary shell cuts off redundant sheaths through the cutting piece, so that the sheaths are cut neatly, and the subsequent assembly of the matched ring is facilitated.
