Deep sea mercury liquid level gauge

Abstract

The invention discloses a deep-sea mercury level gauge which is characterized by comprising an insulating layer; the insulating layer is a long strip and is fixed on the inner wall of the mercury pot of an underwater robot in a vertical shape. A resistance layer and a conductive layer are arranged on the insulating layer; both the resistance layer and the conductive layer are long strips; the lengths of the resistance layer and the conductive layer are equal and are shorter than the insulating layer; the two ends of the resistance layer and the conductive layer are parallel and level and keep clearances with the two ends of the insulating layer. The sum of the widths of the resistance layer and the conductive layer are less than the width of the insulating layer and a resistance is left between the two layers; the upper ends of the resistance layer and the conductive layer are connected with a level gauge by a lead. The deep-sea mercury level gauge can be adopted to accurately measure the liquid level of the mercury and can avoid the pollution to the environment and the harm to the human body caused by the leakage of the mercury. The deep-sea mercury level gauge is applicable for measuring the liquid level of the mercury pot in the pose adjusting system of the deep-sea underwater robot.

Description

technical field [0001] The invention relates to a liquid level measuring device. Specifically, it is a liquid level gauge used to measure the mercury liquid level, which is suitable for measuring the liquid level of mercury tanks in the posture adjustment system of deep sea underwater robots. Background technique [0002] It is known in the shipbuilding industry that deep sea underwater robots are equipped with attitude adjustment devices. The attitude adjustment device is to arrange a mercury tank at both ends of the bow and stern of the underwater robot. The lower part of the mercury tank is filled with mercury, and the mercury in the two tanks is connected with each other by means of pipelines. There is hydraulic oil on the upper part of the mercury tank, and the hydraulic oil is in direct contact with the mercury. When working, the hydraulic oil in one tank flows to the other tank through the hydraulic oil pump, and then the mercury in one tank flows to the other tank,...

AI Technical Summary

Problems solved by technology

At present, the monitoring of the mercury liquid level in the mercury tank is roughly judged based on the real-time inclination value of the underwater robot, and accurate liquid level measurement cannot be performed.

Since the mercury level in the mercury tanks cannot be accurately measured, there is no way to control how much mercury flows from one tank to another

Therefore, it is difficult to prevent mercury from leaking out of the tank

Mercury is a harmful substance. Once leaked, it will not only pollute the environment, but also cause harm to the human body.
