The hydraulic planger pump 22 that is provided with circuit control panel 10 and is driven by electrical motor 19 in pressure shell, electrical motor 19 is connected with a storage battery 7, makes electrical motor 19 obtain power supply supply.Described column type pressure shell is short-thick type, has expanded the diameter of buoy, and this housing is divided into shell 17 and inner casing 21, and described shell 17 and inner casing 21 are the cylinder-like structure of both ends open, and shell 17 is set in the outside of inner casing 21, and both are sealed and matched and are removable; Upper end cover 12 links together by upper flange 11 and shell 17, and bottom end cover 5 links together by lower flange 6 and inner casing 21.Upper end cover 12, upper flange 11 and shell 17 threes connect by bolt 16; Bottom end cover 5, lower flange 6 and inner casing 21 threes link together by bolt 23 too.In enclosure interior, one hydraulic actuating cylinder is installed, the cylinder barrel 8 of this hydraulic actuating cylinder is fixed on lower flange 6, and the piston rod 18 coordinating with cylinder barrel 8 is connected with upper flange 11, and hydraulic planger pump 22 communicates with cylinder barrel 8 by oil circuit.
Because buoy need to carry out in seabed operation, so connecting part, each all adopts seal approach.I.e. junction between buoy inner casing 21 and shell 17, installs the mounting hole of satellite antenna 14 and sensor 13, all can adopt seal with elastometic washer.
The sensor is survey sensor and pressure sensor.
Outer cover at above-mentioned housing is provided with protection leather bag 9; the two ends of this protection leather bag 9 are connected with upper and lower flange; this leather bag can be protected inner casing 21 and shell 17; thereby make housing not be subject to marine corrosion; thereby increase the whole service life of buoy, also give between inside and outside shell auxiliary seal approach is provided.This leather bag communicates with hydraulic planger pump 22 by high pressure fuel pipe, on the high pressure fuel pipe between leather bag and hydraulic planger pump 22, is provided with solenoid directional control valve 24.This leather bag can further change the volume of buoy.When needing buoy to slip into the seabed below 2000 meters, only hydraulic oil need be injected among leather bag, increase the volume of leather bag, thereby further increase the buoyancy of buoy.When running into special sea situation or cause buoyancy inadequate because buoy period of service is long, be that buoy more than 2000 meters is not just having enough buoyancy to make its floating, now hydraulic planger pump can be injected into a part of hydraulic oil in buoy inner casing in leather bag, increase the volume of buoy, and then increase buoy buoyancy, make buoy floating.
In the bottom of bottom end cover 5, a float 4 has also been installed, this float 4 may be connected on bottom end cover 5 by bolt of rear end plate 26, at float 4 and bottom end cover 5 junctions, can adopt seal with elastometic washer.
On the oil circuit between above-mentioned hydraulic planger pump 22 and cylinder barrel 8, be provided with solenoid directional control valve 25.
One vacuum pump 15 is also installed on upper flange 11, when buoy rises to sea level, vacuum pump 15 is started working, buoy inner chamber is evacuated, keep the certain degree of vacuum of buoy inner chamber, improved to a certain extent the sealing effectiveness of buoy, also made the zero device in buoy avoid ingress of air and cause oxidation simultaneously.
Buoy principle of work of the present invention, in the time will increasing buoy volume: 19 power supplies of 7 pairs of electrical motors of storage battery, electrical motor 19 drives hydraulic planger pump 22 to rotate, by solenoid directional control valve 25 by the cylinder barrel 8 of high pressure oil injection liquid cylinder pressure, the piston rod 18 of hydraulic actuating cylinder is released, thereby promotion upper flange 11 and lower flange 6 are separated from each other, thereby drives shell 17 and inner casing 21 mutually to move, buoy volume increases, buoy floating.After arriving sea, solenoid directional control valve 25 obtains electric, closes oil supply loop, and buoy floats on sea.
When running into special sea situation, when causing buoyancy because buoy period of service is long not or slipping into the seabed below 2000 meters, need further to increase the buoyancy of buoy, now solenoid directional control valve 25 must be electric, closes hydraulic actuating cylinder oil supply loop, solenoid directional control valve 24 dead electricity, hydraulic planger pump 22 injects the hydraulic oil in buoy chamber among leather bag, for buoy provides buoyancy aid, after arriving sea, solenoid directional control valve 24 obtains electric, close leather bag oil supply loop, buoy floats on sea.
When buoy sinks, need to reduce volume, solenoid directional control valve 24 dead electricity, hydraulic planger pump 22 quits work, hydraulic oil pushes back hydraulic oil among buoy inner chamber by the pressure of leather bag and the pressure of seawater, solenoid directional control valve 25 dead electricity, the hydraulic oil in hydraulic actuating cylinder pushes back buoy inner chamber by the pulling force of the leather bag of buoy inner chamber degree of vacuum, sea pressure and connection buoy inside and outside shell by hydraulic oil, and buoy sinks.While arriving seabed one km, pressure sensor is passed to solenoid directional control valve 25 by signal, and solenoid directional control valve 25 must be electric, and pressure oil stops pushing back among buoy inner chamber, and buoy stays in one km place, seabed; Through solenoid directional control valve 25 dead electricity after a while, pressure oil is pushed back buoy inner chamber again, and buoy volume further dwindles, and buoy continues to sink; While arriving seabed two km, pressure sensor transfers signals to solenoid directional control valve 25, and solenoid directional control valve obtains electricly, and pressure oil stops being pushed back buoy inner chamber, and buoy volume stops dwindling, and buoy stays in two km places, seabed.
Sea pressure pushes back buoy inner chamber by the high pressure oil in leather bag by solenoid directional control valve 24, and buoy volume reduces; The pulling force of sea pressure, buoy inner chamber vacuum pressure, protection leather bag 9 pushes back buoy inner chamber by the high pressure oil in Barrel of Hydraulic Cylinders 8 by solenoid directional control valve 24, and buoy volume reduces.
Its principle of work of axial-flow type wave energy generating set that bottom end cover connects is to utilize sleeve 1 by bucket maritime interior waters and the outside seawater isolation of sleeve, form inner lead, when buoy floats up to sea along with the motion of wave, water formative in sleeve and outside sleeve is to motion, promoting impeller 3 rotates, impeller flow guiding head 2 inner geares synchronously rotate, the external gear 29 that drive is engaged with rotates, external gear 29 drives coaxial gear 27 to rotate, in-line gears and electrical generator 28 multiplying wheel engagements, drive generator amature rotates, and then generating, by wire, power delivery to the storage battery 7 in buoy shell is stored.In like manner, buoy floating and dive excessively in, the inside and outside seawater of sleeve, because the existence of inner lead in sleeve forms relative motion, promotes wheel rotation, and then driven gear rotates and generates electricity.
Buoy movement process of the present invention is: first buoy is thrown in to the marine site to required measurement, start operation; Carry out communication with satellite, obtain position and the service condition of buoy; Communication finishes rear buoy and shrinks shell, starts dive; Dive stays for some time when dark to a km sea; Buoy continues to shrink shell dive; When arriving 2000 meters of seabeds, stay for some time; Buoy extends shell and starts floating; In the process of floating, measure the data of required collection and store; Buoy rises to sea level, at this moment the shell of buoy be elongated to the longest with guarantee enough buoyancy make buoy floating across the sea with the stationarity that keeps buoy, be convenient to and being connected and communication of satellite; Buoy continues to shrink shell dive, and in sounding buoy floating-upward process, survey sensor is constantly measured the data such as temperature, salinity, level of oxygen and pollutant load of seawater.Arrive behind sea by satellite transmitter via satellite communication antenna take off data is sent.In buoy floating, dive and floating while having wave motion across the sea, all can produce electric energy is battery charge.Repeat above process.
