Abstract
The utility model discloses a water resistance test device for underwater cables. The water resistance test device comprises a tube body and a bracket mounted below the tube body; at least four connecting pipes are integrally arranged on the tube body, wherein the four connecting pipes are respectively connected with a pressure gauge, a water inlet pipe, a water outlet pipe and supercharging equipment; and sealing devices are respectively arranged at two ends of the tube body. The water resistance test device is characterized in that: each sealing device comprises end heads and sealing covers; the end heads are fixedly connected to end parts of the tube body; sealing rings are arranged in the end heads; pressure plates are arranged at two ends of the sealing rings; each pressure plate is provided with a through hole of which the hole diameter is equal to the outside diameter of an underwater cable to be tested; and the sealing covers press on the pressure plates at external sides and are fixedly connected with the end heads. The water resistance test device for the underwater cables has the advantages that: the water-resisting pressure and the water impermeability of the underwater cable to be tested can be tested by putting the underwater cable to be tested into the tube body, fully filling the sealed tube body and supercharging; and an observation mechanism is arranged on the tube body, and thus, the test conditions of the underwater cable in the tube body can be observed in real time.
