Abstract
The invention discloses a deep-sea mercury hydraulic system, which is characterized by including a head mercury tank, an end mercury tank and a hydraulic oil tank. The upper parts and the lower parts of the head mercury tank and the end mercury tank respectively have hydraulic oil and mercury. The hydraulic oil tank is filled with hydraulic oil and is provided with a proportion valve, an oil pump, an electric motor and a safety valve; the oil inlet of the oil pump is communicated with the hydraulic oil in the hydraulic oil tank and the oil outlet of the oil pump is connected with a pressure port of the proportion valve. The oil return port of the proportion valve is communicated with the hydraulic oil in the hydraulic oil tank and the two outlets of the proportion valve are respectively communicated with the upper parts of the internal cavities of the head mercy tank and the end mercury tank by means of pipelines and the lower parts of the head mercury tank and the end mercury tank are communicated with each other by means of mercury pipes. The deep-sea mercury hydraulic system can not only prolong the service lives of the pump, the pipelines and the valves, but also can avoid the environmental pollution caused by the leakage of mercury, and is suitable for adjusting the head weight and end weight of underwater robots in deep-sea.
Description
Technical field
The present invention relates to a kind of deepwater robot form regulation system.Specifically, be the deep sea mercury hydraulic system that is used for regulating deep-sea under-water robot initial and end weight.
Background technology
Know all that in the shipbuilding industry deep-sea under-water robot in the operation process, for adapting to the needs of various varying environments, needs adjust its athletic posture in real time under water.Traditional method of adjustment all is to adopt at the different parts of robot weight is installed,, when needing, realize the adjustment of its attitude by discharging weight.Owing to be subjected to the locus and the deadweight restriction of robot, in a single day the entrained weight of robot discharges and finishes, and just can't proceed the attitude adjustment.Therefore, this method is very impracticable.In order to address this problem, the someone attempts to adopt mercury to come the athletic posture of under-water robot is adjusted.Mercury is a kind of liquid metal, and its proportion is bigger, and moving very, the mercury of small size just can make under-water robot obtain bigger inclination angle.But mercury is toxic substance, and a lot of metals are all had stronger corrosive property, if directly adopt water pump, pipeline and valve to come mercury is carried out pumping, can reduce the service life of water pump, pipeline and valve.In case and these water pumps, pipeline and valve damage, mercury will leak, and will pollute environment.
Summary of the invention
The problem to be solved in the present invention provides a kind of deep sea mercury hydraulic system.This deep sea mercury hydraulic system not only can prolong the service life of water pump, pipeline and valve, and can avoid because of mercury leakage, pollute to environment.
For addressing the above problem, take following technical scheme:
Deep sea mercury hydraulic system characteristics of the present invention are to comprise first mercury jar, tail water silver jar and hydraulic reservoir.The upper and lower part of initial and end mercury jar has hydraulic oil and mercury respectively.Be filled with hydraulic oil in the hydraulic reservoir and be provided with apportioning valve, oil pump, motor and safety valve, the hydraulic oil in the oil suction of oil pump and the hydraulic reservoir is communicated with, and its oil outlet links to each other with the pressure port of apportioning valve.Hydraulic oil in the return opening of apportioning valve and the hydraulic reservoir is communicated with, and two delivery port is connected by the inner chamber top of pipeline with initial and end mercury jar respectively, is connected by mercury tube between the lower lumen of initial and end mercury jar.
Take such scheme, have the following advantages:
Because deep sea mercury hydraulic system of the present invention comprises first mercury jar, tail water silver jar and hydraulic reservoir.Be filled with hydraulic oil in the hydraulic reservoir, the upper and lower part of initial and end mercury jar has hydraulic oil and mercury respectively.Proportional valve oil pump and motor and safety valve in the hydraulic reservoir, the interior hydraulic oil of the oil suction of oil pump and hydraulic reservoir is communicated with, and its oil outlet links to each other with the pressure port of apportioning valve.Hydraulic oil in the return opening of apportioning valve and the hydraulic reservoir is communicated with, and two delivery port is connected by the inner chamber top of pipeline with initial and end mercury jar respectively, is connected by mercury tube between the lower lumen of initial and end mercury jar.During work, rotate oil pump oil suction and pressurization in the hydraulic reservoir by the motor-driven oil pump.The oil pump outlet is delivered to the hydraulic oil pump in the jar in the head and the tail mercury jar in another jar through apportioning valve, rely on hydraulic oil the mercury that promotes in the head and the tail mercury jar of pressure in two jars, move, thereby regulate the distribution of weight of robot head and the tail, to reach the purpose that attitude is regulated.Like this, oil pump only contacts with hydraulic oil with apportioning valve, and does not contact with mercury, thereby has avoided the corrosion of mercury to oil pump and apportioning valve, has prolonged the service life of oil pump and apportioning valve.Do not contact with apportioning valve owing to oil pump again, thereby avoided the mercury leakage, can not pollute to environment with mercury.
Description of drawings
Accompanying drawing is a deep-sea of the present invention water hydraulic system schematic.
The specific embodiment
As shown in drawings, deep-sea of the present invention water hydraulic system comprises first mercury jar 1, tail water silver jars 9 and hydraulic reservoir 3.Mercury is equipped with in the bottom of first mercury jar 1 and tail water silver jar 9, and hydraulic oil is equipped with on their top.Be filled with hydraulic oil in the hydraulic reservoir 3, apportioning valve 4, oil pump 6, motor 7 and safety valve 5 are installed in it.Wherein, the hydraulic oil in the oil suction of oil pump 6 and the hydraulic reservoir 3 is communicated with, and its oil outlet links to each other with the pressure port P of apportioning valve 4.Hydraulic oil in the oil return inlet T of apportioning valve 4 and the hydraulic reservoir 3 is communicated with, two delivery port A and B are connected by the inner chamber top of pipeline 2 with first mercury jar 1 and tail water silver jar 9 respectively, are connected by mercury tube 10 between the lower lumen of first mercury jar 1 and tail water silver jar 9.
In the oil outlet bypass of oil pump 6, be connected to safety valve 5, be connected to pressure compensator 8 on the hydraulic reservoir 3.
During work, drive oil pump 6 by motor 7 and rotate, oil pump 6 is from hydraulic reservoir 3 interior oil suction and pressurizations.Oil pump 6 outlets are delivered to the hydraulic oil pump in the jar in head and the tail mercury jar 1 or 2 in another jar through apportioning valve 4, the pressure of dependence hydraulic oil promotes mercury and moves in two jars, thereby regulate the distribution of weight of robot initial and end, to reach the purpose that attitude is regulated.
