Definitions
- the present invention relates to an underwater vehicle such as a submarine proper.
- this hydraulic energy is extremely well suited to the operation of the masts of the machine such as the slave operation of a periscope, or others.
- the electrical power of the submarine's onboard network is sometimes used for electric actuators for maneuvering this type of mast. This energy does not always have the availability and discretion required.
- the pneumatic energy does not facilitate the realization of a position control. It can be noisy for the crew when using the mast.
- the object of the invention is therefore to solve these problems.
- the subject of the invention is an underwater vehicle of the type comprising a high pressure air edge network and means for maneuvering at least one mast of this machine for hoisting and lowering the same.
- the operating means are connected to oleopneumatic means comprising a first hydraulic part for moving the mast and a second pneumatic part for pressurizing the first part from the high air edge network. pressure of the underwater vehicle.
- the air part of the air / hydraulic separator is connected to the outlet of a distributor comprising at least one inlet connected to pressurized air supply means and an outlet connected to expansion means;
- the pressurized air supply means comprises expander means and connected to the high pressure air edge network;
- the relaxation means comprise at least one detent bottle associated with a silencer for relaxing the air in the underwater vehicle;
- the hydraulic part of the air / hydraulic separator comprises a supply outlet associated with a high-pressure oleopneumatic accumulator and connected through a distributor proportional to a large chamber of a cylinder of means for maneuvering the mast;
- the proportional distributor comprises a return path connected to the hydraulic part of the separator
- the jack comprises a small chamber associated with an oleopneumatic back pressure accumulator
- the means for maneuvering the mast comprise a jack whose rod is fixed.
- FIG. 1 It has in fact shown in this figure, a block diagram illustrating the structure and operation of a power supply installation of maneuvering means of at least one mast of an underwater vehicle.
- maneuvering means allow for example the maneuver as the hoisting and the setting down of a mast of the machine such as for example a periscope mast of a submarine proper.
- These operating means are designated by the general reference 1 in this figure and then comprise for example at least one operating cylinder whose rod 1 is fixed and the body 1b mobile for the embodiment shown.
- the underwater vehicle also comprises a high-pressure onboard air network, designated by the general reference 2 in this figure.
- this edge network 2 may, for example, be an on-board network at a pressure of between 150 and 250 bars in a current environment.
- the means 1 for maneuvering the mast comprise oleopneumatic means designated by the general reference 3 in this figure, having a first hydraulic part 4, the mast displacement, and a second part pneumatic 5, pressurizing the first part 4, from the high-pressure air edge network 2 of the underwater vehicle.
- an air / hydraulic separator designated by the general reference 6 in this figure, the air portion 7 is associated with the second pneumatic portion 5 of the oleopneumatic means 3 and whose hydraulic part is associated with the first hydraulic part 4 of these oleopneumatic means 3, as will be described in more detail below.
- the air portion 7 of the air / hydraulic separator 6 is indeed connected to the output of a distributor, for example electrically controlled, designated by the general reference 8, and having at least one input connected to means supplying air under pressure, designated by the general reference 9, and an outlet connected to expansion means, designated by the general reference 10.
- the pressurized air supply means 9 comprise, for example, means forming a pressure reducer, designated by the general reference 1 1, thus making it possible to deliver to the rest of the circuit, a pressure for example at 150 bar, from a nominal pressure of 250 bar from the high-pressure on-board air system 2.
- the means of relaxation comprise, for their part, for example at least one expansion bottle, designated by the general reference 13 in this figure, associated with a silencer for relaxing the air in the rest of the underwater vehicle, this silencer being designated by the general reference 14.
- the hydraulic part 15 of the air / hydraulic separator 6 comprises a supply outlet associated with a high pressure oleopneumatic accumulator, designated by the general reference 16 in this figure, and connected through a proportional distributor 17, to a large chamber of the jack maneuvering means 1 of the mast of the machine.
- the proportional distributor 17 also comprises a return path connected to the hydraulic part 15 of the separator 6.
- maneuvering means 1 of the mast comprise the jack, whose rod is for example fixed and that the output and the return path of the hydraulic portion 15 of the separator 6 are associated with non-return valves, designated respectively by references 18 and 19.
- the small cylinder chamber of the operating means 1 is associated with an oleopneumatic backpressure accumulator, or recall, designated by the general reference 20 in this figure.
- an oleopneumatic backpressure accumulator, or recall designated by the general reference 20 in this figure.
- the principle of the oleopneumatic cylinder is diverted to the separator located upstream of the proportional distributor, operating at the hoisting and the setting down of the mast.
- This separator feeds a reserve of hydraulic fluid at high pressure, carried by an oleopneumatic accumulator, to store a little more oil than it takes to perform a full stroke of deployment of the mast.
- This separator is itself fed by a network of compressed air from the edge by means of a pressure regulator.
- an expansion volume is arranged downstream of the air distributor towards the purge in the edge, so as to create a rapid expansion in the separator and consequently if the distributor 17 is in the return position, in the large chamber of the cylinder of the maneuvering means of the mast.
- the high-pressure air network edge ensures, as has been indicated above, a pressure for example between 150 and 250 bars in the current environment.
- the flash pressure of 150 bar is used as an example.
- the on-board air network after expansion at 150 bars, is connected to an electrical distributor operating in the servo logic.
- the output U of this electrical distributor is connected to the pneumatic chamber of the separator.
- the return outlet R of the dispenser is connected to an expansion bottle, downstream of which is a diaphragm, and a silencer slowly releasing the air relaxed in the rest of the edge.
- the separator 6 may be constituted by a conventional high-pressure piston accumulator, diverted from its traditional use.
- This separator has two hydraulic outlets equipped with nonreturn valves, respectively connected to the ports P and R of the proportional hydraulic distributor 17. Between the separator and the orifice P thereof, a high pressure oleopneumatic accumulator constitutes the hydraulic energy reserve, which can be pre-loaded before controlling the hoisting of the mast so as to mask the slowness intrinsic to the pneumatic floor.
- the proportional distributor 17 is useful both in hoisting and downshifting, in order to control both the speed and the position of the mast in both directions.
- the output U of the proportional distributor is connected to the large chamber of the hoist cylinder.
- the small cylinder chamber of the operating means 1 is connected to an oleopneumatic booster or back-pressure accumulator.
- the air distributor 8 is actuated for a predetermined time delay just necessary to fill the accumulator.
- the mast can be enslaved in hoisting, thanks to the high-pressure reserve, but it can also be enslaved in the counter-pressure, in the small chamber pushing the piston of the separator.
- the air distributor 8 is again activated to inflate the high pressure accumulator.
- the air distributor 8 receives an order of expansion regardless of its previous state and the state of the compression timer.
- the proportional hydraulic distributor receives parallel but dissociated orders from the air distribution logic.
- the control law of the proportional distributor is then a conventional law for maintaining the position and the speed.
- the mast operates, for example, in response to a rallying instruction of a position, with clipping according to a maximum speed threshold of the mast.
- the clipping speed can be set or programmed according to the measured difference between the set position and the position of the mast at a given time.
