[0002] With the rapid development of optical fiber communication technology and the support of national policies, the demand for optical cables has increased year by year. The service life of optical cables has attracted great attention from people. Among them, the water seepage performance of optical cables is one of the main indicators for evaluating the quality of optical cables and is also an important indicator to ensure the service life of optical cables. During the use of optical cables, if water seeps into the cable core, that is, around the optical fibers, it will cause an increase in the water peak attenuation of the optical cable, corrosion of the metal strengthening members in the cable core, and even water entering the optical cable joint box along the cable core, bringing a huge impact to the entire information communication. The water seepage test device for optical cables can detect the water seepage performance of optical cables. In the prior art, most of the water seepage testing machines are the solutions disclosed in, for example, the patent (publication number: CN208505539U), which have a simple structure and low manufacturing cost. However, when in use, it is necessary to manually add tap water into a circular tube with a small diameter, and the operation is inconvenient. Content of the Utility Model

The other input port of the tee joint is connected to a vertical air pipe. A plurality of horizontally arranged air pipe joints are installed on the upper part of the upright frame. The upper end of the air pipe is correspondingly connected to the air pipe joint. A water pipe elbow is installed on the upper part of the water tank. A float valve is installed at the inner end of the water pipe elbow. There are several cable waterproof joints, which are horizontally installed on the front side of the water seepage valve plate. The cable waterproof joints are in one-to-one correspondence and communication with the switching valves through the water seepage valve plate.
