Description

[Detailed Description of the Invention] The present invention relates to an improvement of a water running test device for waterproof cables.

Water running conditions of waterproof cables are tested to determine whether their characteristics are good or bad.

Conventionally, as shown in FIG. 1, this testing device has been used to conduct water running tests using a device in which one water supply pipe is attached to one sample cable 4.

Note that a is for carrying out a water running test at the end, 2 is an L-shaped tube, b is for carrying out a water running test at the middle part of the cable, and 3 is a T-shaped tube.

However, with this conventional test equipment, it is inconvenient because it is necessary to monitor all samples in order to maintain a specified water level during a long test period, and it is also difficult to measure the water running length. In order to do this, the test water in which fluorescent dye was added and melted had the disadvantage that it could not be recovered even after the test was completed due to foreign substances such as dirt and dust settling around the sample and the mixing of waterproof compound into the test water.

The purpose of the present invention is to provide an improved waterproof cable water running test device that eliminates the above-mentioned drawbacks of the prior art, allows easy control of the test water level, and saves test water. The gist of this is that by providing multiple branched water supply pipes so that water can be supplied from one water storage tank to multiple waterproof cables at the same time, and by providing a valve on each water supply pipe. A waterproof cable water running test device is characterized in that it is configured to enable opening and closing of water supply.

Fig. 2 shows an embodiment of the test device of the present invention, where 5 is a water storage tank, and the bottom or lower side of the tank is connected to a water supply pipe 6 whose lower part is branched into a plurality of octopus legs. ing.

Reference numeral 7 denotes a valve attached to the tip of each branched water supply pipe 6, and the water supply is opened and closed by opening and closing the valve 7.

8 is an L-shaped pipe, 9 is a T-shaped pipe, and each water supply pipe 6
This valve is for connecting the waterproof cable 10 that is a sample to the valve 7.
By adjusting the opening and closing of the test tube, it is possible to start and end the test without affecting other samples.

Reference numeral 11 denotes a water level measuring scale provided in the water storage tank 5, which is adjusted so that a predetermined water level is always maintained during the test.

According to the test device of this embodiment constructed in this way,
Water running tests on multiple samples can be done by simply monitoring and adjusting the water level in one water tank.
Can be simplified.

It also has the advantage that water used for testing can be saved.

In the embodiment described above, the water storage tank is made of metal, and a part of its surface is embedded with transparent glass or plastic with a scale, but the water storage tank itself is made of transparent glass or plastic. It is also possible to have a water level display scale on its surface, or a water level display tube connected to the tank at the bottom or lower side of the tank.

Furthermore, it is also possible to integrate the T-shaped pipe or the L-shaped pipe with the water supply pipe in advance, or to provide the water supply pipe with a filter to filter out foreign substances such as dirt and dust. It should not be construed in a limited manner.

As explained above, according to the present invention, it is possible to provide an excellent water running test device for cables that prevents water running, which solves the drawbacks of the prior art, and has great practical value.
