The invention is described in further detail below with reference to the accompanying drawings:
fig. 1 is a schematic diagram illustrating an optical fiber winding method for improving consistency of an optical fiber hydrophone according to an embodiment of the present invention. The optical fiber winding method for improving the consistency of the optical fiber hydrophone comprises the following steps:
the method comprises the following steps: measuring the diameter of the cross section of the optical fiber ring 1, obtaining the perimeter of the cross section according to the diameter, setting the number of turns of the wound optical fiber, and obtaining the length of the wound optical fiber according to the perimeter of the cross section and the number of turns of the wound optical fiber;

step three: the optical fiber which is led out from the fiber carrying disc 2 and has the optical fiber winding tension in the step two is wound on the fiber guide wheel 3, guided by the fiber guide wheel 3, passes through the glue inlet wheel 8 to enable the outer surface of the optical fiber to be coated with glue, and then enters the fiber inlet groove 4 of the optical fiber ring mandrel 11;
step four: the optical fiber entering the fiber groove 4 is led into the groove of the first clamping groove 71 arranged at one end of the elastic wall 12, the optical fiber ring 1 is rotated, the optical fiber winds the outer surface of the optical fiber winding area 5 arranged on the elastic wall 12 from one end of the elastic wall 12 to the other end of the elastic wall 12 side by side to form a first layer of optical fiber, then the optical fiber continuously winds the optical fiber back to one end of the elastic wall 12 side by side from the other end of the elastic wall 12 through the groove of the second clamping groove 72 arranged at the other end of the elastic wall 12, and the optical fiber is sequentially and circularly wound until the set number of turns of the optical fiber is.
In the first step, as shown in fig. 1 and 2, the cross section of the optical fiber ring 1 is a circle, the diameter of the cross section of the optical fiber ring 1 is accurately measured by a caliper, the circumference of the cross section is calculated, the number of turns of the optical fiber wound on the optical fiber ring 1 is set, and the length of the optical fiber on the optical fiber ring 1 is accurately calculated, so that the total length of the optical fiber wound on each optical fiber ring 1 is ensured to be consistent.
In the second step, 3 factors of the wall thickness of the elastic wall 12, the optical fiber winding tension and the optical fiber length are selected, and the reasonable optical fiber winding tension is determined by adopting an L4(3) orthogonal test method, so that the tight coupling of the optical fiber and the elastic wall 12 is ensured, and the problem that the optical fiber is damaged due to overlarge tension in the manufacturing process is solved.
In the third step, as shown in fig. 1 and 2, a part of the optical fiber is slowly drawn out from the fiber carrying disc 2, and after passing through the fiber guide wheel 3, a vertical angle is formed with the axial direction of the optical fiber ring 1, the fiber carrying disc 2 is slowly rotated to slightly tighten the optical fiber, and then the optical fiber reaches the glue inlet wheel 8, the contact area between the glue inlet wheel 8 and the optical fiber is adjusted, so that the glue is uniformly coated on the outer surface of the optical fiber, and the stress of the subsequent optical fiber ring 1 caused by the non-uniform glue amount is reduced.
