Abstract

The invention discloses a combined-type underwater hydraulic pump station and relates to the technical field of hydraulic pump stations. The combined-type underwater hydraulic pump station comprises apump station shell and an intermediate junction box, the intermediate junction box is welded to the pump station shell, and water sealing connector seat mounting holes are formed between the pump station shell and the intermediate junction box. A pressure equalizing mechanism is arranged on the intermediate junction box and comprises a connecting rod and an elastic element, the connecting rod isof a hollow structure, and one end of the connecting rod communicates with a box cavity of the intermediate junction box. A cavity is formed in the other end of the connecting rod, the elastic elementis arranged at an opening of the cavity to seal the cavity, and water sealing connector seats are connected to water sealing junction seats of all sensors in the pump station shell through intermediate cables. The box cavity of the intermediate junction box is full of oil. According to the combined-type underwater hydraulic pump station, smooth operation of an operation system can be effectivelyguaranteed, and the reliability of the operation system is guaranteed.

Description

technical field [0001] The present invention relates to the technical field of hydraulic pump stations, more specifically to a combined underwater hydraulic pump station, in particular to a combined hydraulic pump station that integrates an intermediate wiring, a branch box and a hydraulic pump station. Background technique [0002] With the development of water conservancy, hydropower and marine engineering, the use of underwater machinery and tools is increasing day by day. Underwater operations often use underwater hydraulic power sources, and cables are used to supply power to underwater hydraulic pump stations and issue operating instructions. Underwater sensors also pass cables. Pass the signal to the control system on the water. [0003] There are usually two ways to realize power supply and signal transmission, one is to set up an independent intermediate junction box / box. The main cable is connected to the intermediate junction box / box through a watertight socket, ...
