The utility model discloses a cloth dyeing device, including dyeing pool, the left side upper end of this dyeing pool is provided with the feeding roller, the right side upper end is provided with the discharge roller, and the pool bottom left side, the middle side and the right side of dyeing pool all are provided with the conveying roller, and the cloth that needs to be dyed passes the left side feeding roller feeding, passes three conveying rollers of pool bottom again and feeds, realizes the discharge from discharge roller, be provided with dye in the dyeing pool. The cloth that needs to be dyed in the device enters the dyeing pool through the feeding roller, then passes three conveying rollers and is conveyed downward, realizes the discharge through the discharge roller of upside after again, and be provided with dye in the dyeing pool, and the cloth is soaked and dyed through dye when passing the dyeing pool, realizes the discharge from the discharge roller when corresponding complete dyeing, and the structure is reasonable.

A locking structure is arranged between a lower shell and an upper cover plate, the interior of the lower shell is divided into an upper cavity and a lower cavity through a detection partition plate, the upper cavity is divided into an outer cavity and an inner cavity through a sampling baffle ring, a plurality of storage cylinders are fixedly installed in the outer cavity, air inlet branch pipes and air outlet branch pipes are further arranged in the storage cylinders, and the air inlet branch pipes and the air outlet branch pipes are connected with the upper cover plate. The air inlet branch pipes and the air outlet branch pipes penetrate through the detection partition plate to enter the lower cavity, an air inlet header pipe and an air outlet header pipe are arranged in the lower cavity, the air inlet branch pipes are provided with corresponding electromagnetic valves, the air inlet header pipe is connected with an air extracting pump, an extractor pipeline of the air extracting pump penetrates through the lower shell to be communicated with the outside, and the air outlet header pipe also penetrates through the lower shell to be communicated with the outside. An irradiation hole is formed in the sampling baffle ring, an illumination light source is rotationally mounted on the upper cover plate, and a light intensity detection sensor and a limiting device are arranged in the outer cavity; the device can automatically carry out absorbance detection after a plurality of U-shaped absorption tubes are sampled, so that the sampling accuracy is ensured, the light is effectively avoided, and the manual complexity is reduced.

The utility model provides an optical module and an optical fiber link online monitoring system, and relates to the technical field of optical communication. The optical module comprises an optical detector, a trans-impedance amplifier and a monitoring unit, and the optical detector is used for receiving a data optical signal and a detection optical signal which are input through an external optical fiber and converting the data optical signal and the detection optical signal into a data electric signal and a detection electric signal respectively. The input end of the transimpedance amplifier is electrically connected with the optical detector so as to receive data electric signals and detection electric signals output by the optical detector. The low-speed sampling end of the transimpedance amplifier is electrically connected with the sampling part of the monitoring unit, and the sampling part obtains a sampling signal through the low-speed sampling end and transmits the sampling signal to the control and processor; and the control and processor is used for processing an alternating current sampling signal in the sampling signals so as to determine the fault position of the external optical fiber. On the basis of low cost, real-time monitoring and online breakpoint detection can be carried out on the optical fiber link.
