Description

Technical Field

[0001] The utility model relates to the technical field of aeration equipment application, and in particular to a customized optical cable suitable for distributed optical fiber aeration monitoring. Background Art

[0002] Aeration is a water treatment technology, which is mainly used to add oxygen to sewage to support the biodegradation process of microorganisms. It introduces air or pure oxygen into the sewage to make the sewage in the pool contact with the air and oxygenate it, and stirs the liquid to accelerate the transfer of oxygen in the air to the liquid. Distributed aeration is one of the commonly used methods in the aeration process. It is equipped with multiple groups of tubular aerators to fully ensure the aeration effect.

[0003] When existing distributed aeration is used, optical fiber detection is sometimes used to monitor the working status of multiple groups of tubular aerators, so as to avoid abnormal working of some tubular aerators and the staff's failure to find them in time. However, the current optical fiber detection method often makes the operation more cumbersome and troublesome when fixing the optical fiber on the pipe in order to ensure the contact surface between the optical fiber and the pipe, such as through spiral winding and pasting.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-Figure 6 As shown, the utility model is a customized optical cable suitable for distributed optical fiber aeration monitoring, including a plurality of first clamping fixtures 2 arranged at one end of the outer wall of a main body 1 of a distributed aeration device, a second clamping fixture 3 is arranged at one end of the first clamping fixture 2, a connecting block 6 is installed on one side of one end of the first clamping fixture 2 and the second clamping fixture 3, a connecting shaft 7 is passed through the top of the connecting block 6, the cross-sectional shape of the first clamping fixture 2 and the second clamping fixture 3 are both arc-shaped, and the first clamping fixture 2 and the second clamping fixture 3 are respectively made as an integrated whole with the corresponding connecting block 6 and U-shaped plate 8, so as to ensure the connection strength of the first clamping fixture 2 with the corresponding connecting block 6 and U-shaped plate 8 during use;

[0029] The central axis of the connecting shaft 7 is perpendicular to the transverse central axis of the connecting block 6, and the connecting shaft 7 is rotatably connected to the connecting block 6, so that the staff can clamp the first clamping fixture 2 and the second clamping fixture 3 at the connection of the tubular aerator on the distributed aeration equipment body 1 by rotating the first clamping fixture 2 and the second clamping fixture 3;

[0030] The first clamping fixture 2 and the second clamping fixture 3 are both provided with a receiving groove 4 on their inner sides, and an optical cable body 5 is arranged inside a group of receiving grooves 4. Both ends of the optical cable body 5 are respectively connected to the signal receiving and transmitting and monitoring equipment. The combination and use method thereof are the same as the existing optical fiber detection method, that is, external vibration, temperature change or medium change, etc. will cause slight vibration or deformation of the optical fiber, thereby causing the signal to fluctuate or the signal fluctuation mode to change, thereby completing the monitoring task. At the same time, during assembly, the optical cable body 5 can be directly squeezed into the receiving groove 4, and then the first clamping fixture 2 and the second clamping fixture 3 are clamped and fixed at the connection of the tubular aerator. Since the aerator will cause slight vibrations in the surrounding area due to bubble bursting and the like during operation, once the vibration stops or changes, it will affect the signal transmission of the optical fiber, thereby allowing the staff to be informed that there is an obstacle in the operation of the tubular aerator;

[0031] At the same time, during the installation process, it is only necessary to insert the optical cable body into the corresponding receiving groove, and to assemble and fix the first clamping fixture and the second clamping fixture in the above manner to complete the laying of the optical cable body, and to ensure that there is a sufficient contact surface at the connection between the optical fiber and the tubular aerator;

[0032] A U-shaped plate 8 is installed on one side of the outer wall of the first clamping fixture 2 and the second clamping fixture 3, and a square groove 9 is reserved on the inner wall of the U-shaped plate 8. A connecting mechanism for fixing the first clamping fixture 2 and the second clamping fixture 3 is arranged in the square groove 9. The connecting mechanism includes a bolt 10, which is arranged inside the square groove 9 and passes through the U-shaped plate 8. A nut 11 is sleeved on the outer side of the bolt 10 near one end. The central axis of the nut 11 coincides with the central axis of the bolt 10, and the nut 11 and the bolt 10 are threadedly connected, so that after the staff completes the combination of the optical cable body 5 with the first clamping fixture 2 and the second clamping fixture 3 and assembles them at the connection of the tubular aerator, the bolt 10 can be passed through the corresponding two sets of U-shaped plates 8 and the nut 11 is screwed onto the bolt 10 to complete the fixation. The operation process is convenient and quick;

[0033] A square fitting frame 12 is installed on the outer side of the end of the bolt 10 away from the nut 11, and the square fitting frame 12 and the square groove 9 form a sliding structure, so that after the bolt 10 is inserted into the square groove 9, the square fitting frame 12 will replace the bolt 10 and fit the inner wall of the square groove 9, so that during subsequent use, the square fitting frame 12 will assist in bearing part of the separation force of the first clamping fixture 2 and the second clamping fixture 3, thereby avoiding deformation or thread wear that may occur easily when conventional bolts are directly used.

[0034] The working principle of the utility model is as follows: one end of the optical fiber is connected to the corresponding equipment according to the existing optical fiber leak detection method and then laid; during the laying process, the optical fiber close to the tubular aerator is squeezed and inserted into the accommodating groove 4 on a group of first clamping fixtures 2 or second clamping fixtures 3; then the first clamping fixtures 2 and the second clamping fixtures 3 are rotated and assembled and clamped at the connection between the tubular aerator and the main pipeline; and the group of first clamping fixtures 2 and second clamping fixtures 3 are fixed by bolts 10 and nuts 11, so that the section of optical fiber is fully attached to and fixed to the tubular aerator; then the optical fiber is fully laid according to the above method, and the outer walls of multiple tubular aerators are covered with the optical cable body 5; finally, the other end of the optical fiber is connected to the corresponding equipment according to the existing optical fiber leak detection method; and the operation process is convenient and quick.

[0035] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
