Description

Technical Field

[0001] The utility model relates to the field of optical fiber monitoring, in particular to a glue bucket used for coating sand particles on optical fibers. Background Art

[0002] Distributed fiber optic sensing technology has been widely used in the field of geotechnical engineering monitoring. Usually, the surface of the optical fiber is relatively smooth, and the coupling effect with the surrounding medium is poor during use. In practical applications, sand can be adhered to the surface of the distributed optical fiber to increase the roughness of the optical fiber, so that it has better coupling with the surrounding aggregate. However, there is currently a lack of devices for coating optical fibers with glue and bonding sand, which makes the glue coating and bonding sand process complicated, and the coating effect is poor, and the sand is unevenly distributed on the surface of the optical fiber. Utility Model Content

[0003] In order to overcome the above technical defects, the utility model provides a glue bucket for coating optical fiber with sand particles, which solves the problem that the process of coating optical fiber with glue and bonding sand particles is complicated and difficult to be uniform.

[0004] In order to solve the above problems, the utility model is implemented according to the following technical solutions.

[0005] A glue bucket for coating sand grains on optical fiber comprises a glue bucket main body, wherein the glue bucket main body comprises a sand bin and a glue bin.

[0006] Further: a glue groove is provided at the bottom of the glue bin, the glue groove is symmetrically concave, and the glue groove is filled with glue.

[0007] Further: the middle part of the glue bin is arranged with a lower rubber wheel and an upper rubber wheel in an up-and-down shape, and the surfaces of the lower rubber wheel and the upper rubber wheel are brushes. When in use, the brush at the bottom of the lower rubber wheel is placed in the glue. The spacing between the lower rubber wheel and the upper rubber wheel can allow the optical fiber to pass through and can be in close contact with the upper and lower brushes, and the optical fiber can cause the lower rubber wheel and the upper rubber wheel to rotate when moving. The two ends of the rotating shaft of the lower rubber wheel and the upper rubber wheel can be fixed to the bin wall.

[0008] Further: the sand bin is filled with sand, and the sand particle size is set according to actual needs.

[0009] Furthermore: through holes are provided on the front and rear walls of the glue bin and the sand bin for the optical fiber to pass through, and the diameter of the through hole is slightly larger than the diameter of the optical fiber.

[0010] Furthermore: when the glue bucket is used, glue is loaded into the glue groove, the optical fiber passes through the through holes of the glue bucket body in sequence and is placed between the lower rubber wheel and the upper rubber wheel, sand is loaded into the sand bin, and the optical fiber is pulled so that it is coated with glue under the rotation of the lower rubber wheel and the upper rubber wheel. When the optical fiber coated with glue passes through the sand bin, the sand is bonded to the optical fiber under the action of the glue, thereby making an optical fiber coated with sand.

[0011] The utility model has the following beneficial effects: the utility model is a glue bucket for optical fiber coating with sand, which can simultaneously complete the optical fiber coating with glue and the bonding with sand, increase the roughness of the optical fiber surface, enhance the coupling effect between the optical fiber coated with sand and the surrounding medium when using the optical fiber, and improve the optical fiber sensing test effect. At the same time, the device has a simple structure, is easy to operate, and greatly improves work efficiency.

[0012] The upper glue wheel ensures that the optical fiber is in close contact with the lower glue wheel. At the same time, the glue of the lower glue wheel will be transferred to the upper glue wheel through the surface, making the glue on the surface of the optical fiber more even.
