Abstract

The invention discloses a deep-sea hydraulic tank with various monitoring functions, which comprises a cylinder. A compensation film, which divides the cylinder into an oil cavity and a seawater cavity, is arranged in the inner cavity of the cylinder; a piston arranged in the seawater cavity is fixed with the compensation film; springs are arranged between the piston and one bottom of the cylinder; and an oil interface is formed at the other bottom of the cylinder. The tank is characterized in that a liquid level sensor, a temperature sensor, a pressure sensor and two metal pins are arranged inside the oil cavity, wherein, the liquid level sensor, the temperature sensor and the pressure sensor are fixed in sequence from top down the cylinder bottom of the oil cavity; the two metal pins are separately fixed on the lower side of the cylinder; a watertight socket is formed at the upper part of the bottom of the oil cavity; and the liquid level sensor, the temperature sensor, the pressure sensor and the two metal pins are connected with the watertight socket through a lead. The multifunctional deep-sea hydraulic tank can prevent electric elements in a hydraulic system from being damaged, thereby ensuring the normal operation of the hydraulic system. The tank can be used for pressure compensation for deep-sea underwater robots.

Description

technical field

[0001] The invention discloses a hydraulic oil tank. Specifically, it is a multifunctional hydraulic oil tank on a deep sea underwater robot for pressure compensation. Background technique

[0002] It is known in the shipbuilding industry that deep sea underwater robots are equipped with hydraulic systems to drive manipulators, pan / tilts, buoyancy adjustment systems, winches and release devices. Due to the high external pressure in deep sea conditions, the hydraulic system must be pressure compensated. Therefore, the hydraulic oil tanks of deep-sea underwater robots are all provided with pressure compensation mechanisms. At present, the hydraulic oil tank on the deep sea underwater robot only has a pressure compensation mechanism, and only has a pressure compensation function, and the function is single. Seawater is conductive, once it enters the hydraulic system, the electrical components will be short-circuited and damaged, making the hydraulic system un...
