Description
Technical field
The present invention relates to a kind of hydraulic driving adjustment device, be specifically related to a kind of hydraulic driving adjustment device of underwater measurement platform, belong to the marine monitoring field.
Background technology
Marine monitoring technology is indispensable basic technology and the information obtaining means that concerns national marine safety, economic development, environmental protection, disaster reduction and prevention.At present, marine monitoring platform commonly used is buoy and submerged buoy system, and the advantage of buoy is to realize data real-time Transmission via satellite, can finish the observation to upper ocean.Its shortcoming is the destruction that is subjected to factors such as fishing boat, storm easily, and more the deep water ocean essential is monitored; The advantage of subsurface buoy is to lay under water, be difficult for being found and destroying, but it is made up of a series of series connection CTD, the current meter (or other observation instruments) of deep-sea grappling usually, shortcoming is to need a large amount of instruments, higher, the complicated operation of expense, and can only can not realize serial section observation at discrete several level up-samplings.Hoistable platform in the past adopts motor drive mode, cause the knotting of cable wire easily, cause the lifting difficulty, in order to improve above-mentioned difficulties, regulate so be necessary to study a kind of hydraulic-driven, adopt the buoyancy adjustment mode to control lifting platform, reliable in action simple in structure, low in energy consumption, and can well overcome because of long-term work causes marine corrosion and microbial adhesion and make problems such as system's lifting difficulty, maximum diving depth reaches 1500m.
Summary of the invention
The invention provides a kind of hydraulic driving adjustment device of underwater measurement platform, adjust the buoyancy of measuring table, thereby realize moving up and down of measuring table by hydraulic driving adjustment device.
Hydraulic driving adjustment device comprises housing, direct current generator, control module, solenoid directional control valve, retaining valve, external pressure sensor, oil sac guard shield, oil sac, throttling valve, hydraulic pump, oil supply pressure sensor and fuel tank, and outer periphery has hoistable platform and measuring table; Fuel tank is installed in the enclosure interior upper end, and hydraulic pump places the fuel tank lower end, and the oil supply pressure sensor is connected in the fuel tank by fluid pressure line, and external pressure sensor is installed in housing bottom; Fuel tank internal is connected on hydraulic pump and the retaining valve by the two-way pressure duct through two solenoid directional control valves, retaining valve is connected on the oil sac by pressure duct, the oil sac guard shield is contained in the oil sac top, hydraulic pump links to each other with oil sac with throttling valve through solenoid directional control valve respectively by pressure duct, the output shaft of direct current generator links to each other with hydraulic pump, control module is installed in the direct current generator below, and hydraulic driving adjustment device is installed in the below of hoistable platform.
Fuel tank places the upper end, and hydraulic pump places the fuel tank lower end, can guarantee the back pressure that hydraulic pump sucks like this, thereby avoids the particular design requirement of fuel tank.Oil sac is contained in hoistable platform inside, with outside contact with sea water.
Because whole hydraulic system oil liquid amount is a definite value, in order to detect oil sac inner fluid volume in real time, just can learn indirectly by detecting fuel tank inner fluid volume, the oil supply pressure sensor is exactly by detecting fuel tank inner fluid pressure, through type p=ρ gh learns fuel tank fluid volume, thereby learn to charge into oil sac inner fluid volume, realize the switching controls of solenoid directional control valve.External pressure sensor is to be used to detect seawater pressure, learn by pressure sea water advanced, thereby determine the duty of system.
The principle of work of hydraulic driving adjustment device: object keeps weight constant, changes its suffered buoyancy in water by changing volume, thereby can finish the lifting of platform with energy seldom, and its principle utilizes gill control to rise and fall the same with fish.Hoistable platform buoyancy adjustment control device keeps weight of object constant exactly, relies on its volume of change to realize the sink-float of hoistable platform in water.The oil sac volume is increased, thereby the buoyancy of hoistable platform is increased gradually and rise.Otherwise, when the hydraulic oil in the oil sac externally is expelled back into fuel tank under the effect of seawater pressure, the oil sac volume-diminished, hoistable platform buoyancy reduces thereupon, when gravity greater than buoyancy, hoistable platform just sinks gradually.
Working method: when system sinks, after hoistable platform cloth is put into and uses the depth of water, to the control module energising, solenoid directional control valve is opened in control module control, and solenoid directional control valve moves to right position, hydraulic pump is by pipeline and throttling valve and oil sac connection, and start the direct current generator counter-rotating, and thereby drive hydraulic pump the oil in the oil sac is turned back in the fuel tank, oil sac shrinks, the hoistable platform volume reduces, and makes hoistable platform sink to the detected precalculated position of external pressure sensor;
When system floats, solenoid directional control valve is opened in control module control, solenoid directional control valve moves to position, a left side, the inlet port of hydraulic pump and fuel tank are connected, hydraulic pump is by pipeline and retaining valve and oil sac connection, and start direct current generator and make it just to change, direct current generator drives hydraulic pump goes into the oil pump in the fuel tank in the oil sac, is increased to the pressure difference of oil supply pressure sensor determination up to the oil sac volume.
Beneficial effect: this device adopts the mode of buoyancy adjustment control gear lifting, simple and reliable for structure, power consumption is extremely low, avoided because system works at the deep-sea for a long time, system's lifting difficulty is destroyed and made to seawater and microorganism to mooring guy, also will improve many shortcomings of traditional anchorage system simultaneously.
