Detailed Description
For the purpose of enhancing understanding of the present invention, the present invention will be described in further detail with reference to the accompanying drawings and examples, which are provided for illustration only and are not intended to limit the scope of the present invention.
Examples
As shown in figure 1, the floating piston type buoyancy regulator comprises a watertight pressure-resistant cabin 2, a regulating pipe 7 and a hydraulic power system 9.
A piston 5 is matched in the watertight pressure-resistant cabin 2 in a sliding mode, and the piston 5 divides the watertight pressure-resistant cabin 2 into an inner liquid chamber 6 and a pressure air chamber 8.
The inner liquid chamber 6 is internally provided with a buoyancy adjusting medium, the inner liquid chamber 6 is communicated outwards through the adjusting pipe 7, and the adjusting pipe 7 is provided with the hydraulic power system 9.
The pressure air chamber 8 is provided with a displacement sensor for detecting the displacement of the piston 5.
When the buoyancy adjusting device is used, the buoyancy adjusting medium in the inner liquid chamber 6 is outwards pumped out or the external buoyancy adjusting medium is pumped back to the inner liquid chamber 6 through the hydraulic power system 9, the piston 5 slides back and forth along with the buoyancy adjusting medium in and out of the watertight pressure-resistant cabin 2 to form the pressure air chambers 8 with different volumes, and then the buoyancy of the watertight pressure-resistant cabin 2 is changed. Because the pressure air chamber 8 is provided with the non-contact displacement sensor, the displacement distance of the piston 5 can be detected in real time, the volume change of the pressure air chamber 8 can be calculated through the displacement distance, and then the change of the buoyancy can be known, namely, the change of the buoyancy can be known in real time by means of the non-contact displacement sensor in the process of controlling the watertight pressure-resistant cabin 2 through the hydraulic power system 9.
If the medium in the watertight pressure-resistant cabin 2 is the same as the liquid in the environment, the medium in the watertight pressure-resistant cabin 2 can be directly pumped out to the environment, and the equipment space is further saved.
The hydraulic power system 9 is positioned in the pressure air chamber 8. The hydraulic power system 9 can be well protected from external corrosion, and meanwhile, the whole body can be better integrated, and the center of gravity of the whole body can be better controlled.
The hydraulic power system 9 is a hydraulic pump. The internal buoyancy adjusting medium can be better conveyed to enter and exit the watertight pressure-resistant cabin 2.
And an expansion bag 1 communicated with the end part of the adjusting pipe 7 is arranged outside the watertight pressure-resistant cabin 2. The medium can be controlled in the watertight pressure-resistant cabin 2 and the expansion bag 1 through the expansion bag 1, the medium is prevented from exchanging with the environment, and the buoyancy regulating medium can flow in a closed space when the buoyancy regulating medium is different from the liquid of the environment.
The pressure air chamber 8 is provided with a buoyancy adjusting controller 3, and the buoyancy adjusting controller 3 is respectively and electrically connected to the displacement sensor and the hydraulic power system 9. The buoyancy adjusting controller 3 can more conveniently monitor and control the displacement of the buoyancy power system according to the displacement of the piston 5 by the non-contact displacement sensor.
The expansion bag 1 is made of rubber. The space expansion and contraction can be better provided.
The displacement sensor is a non-contact displacement sensor. And the piston is not contacted, so that the interference to the piston in the detection process can be avoided.
The non-contact displacement sensor adopts a laser displacement sensor. It is convenient to detect the movement of the piston 5 with higher accuracy.
This scheme adopts non-contact displacement sensor can real-time detection piston 5's displacement volume, and then learns the change of buoyancy, and is higher to piston 5 displacement measurement accuracy, and overall structure mechanical regulation structure still less, simple structure, performance is more stable, combines expansion bag 1 to adjust the medium control with buoyancy in confined space, avoids taking place water pollution and corruption. The watertight pressure-resistant cabin 2 and the expansion bag 1 are communicated through the adjusting pipe 7, the watertight pressure-resistant cabin and the expansion bag can be more flexibly arranged at relative positions, and mass center auxiliary adjustment and control are facilitated in the application of the aircraft. The watertight and pressure-resistant cabin 2 with the rigid structure can avoid shaking in underwater motion, and is beneficial to the stable control of the mass center predictability of underwater equipment.
The scheme has two use modes, wherein one mode is that the buoyancy regulating medium is the same as the liquid in the external environment, for example, the buoyancy regulating medium and the liquid in the external environment are both water, and in this case, the water can be directly pumped into and out of the inner liquid chamber 6 from the external environment without using the expansion bag 1. The other is that the buoyancy regulating medium is different from the liquid in the external environment, for example, the buoyancy regulating medium is hydraulic oil, and at this time, the expansion bag 1 needs to be removed to isolate the buoyancy regulating medium from the external environment, so that corrosion to components can be avoided, and certainly, in actual use, the expansion bag 1 can be used as the buoyancy regulating medium and the liquid in the external environment. Namely, when the adjusting medium is hydraulic oil, the expansion bag is a rubber oil bag, and when the adjusting medium is an environmental water body, the expansion bag is a generalized environmental water body.
Because the expansion bag 1 is connected with the watertight pressure-resistant cabin 2 through the adjusting pipe 7, no new connection relation exists, and the expansion bag 1 can be placed at any position of target equipment; and because the expansion bladder 1 is a rubber soft oil bladder, the expansion bladder can be made into any required shape according to the requirement of installation space, and has more flexibility.
Since the buoyancy adjusting medium is a liquid which is an approximately incompressible body, the deviation between the buoyancy value obtained by measuring the displacement of the floating piston 5 by the non-contact displacement sensor and the volume of actual drainage can be ignored (compression amount deviation); compare this kind of buoyancy regulator of other modes such as flowmeter formula and directly reflected comparatively real displacement volume change, can accomplish high accuracy control, more importantly adopts non-contact displacement sensor to carry out the measurement of buoyancy change volume and does not need repeated calibration buoyancy benchmark zero point its characteristics that have repeatable high precision.
The buoyancy regulator has a simple structure, hydraulic oil always changes under the constraint of unchanged total volume of the internal hydraulic oil when the expansion capsule 1 of the internal liquid chamber 6 moves and distributes, and the change of the shape of the internal liquid chamber 6 is approximate to the linear relation change of a rigid body with a regular shape.
The expansion bag 1 of the buoyancy regulator can be a closed buoyancy regulating system which adopts special hydraulic oil as a regulating medium, and has the advantages that the buoyancy regulating working medium is not easily polluted by external environment, and the buoyancy regulating working medium has the advantages of long service life, high reliability, accurate and stable control and the like; the expansion bag 1 can also be an open buoyancy regulating system which adopts an environmental water body as a regulating medium, at the moment, the expansion bag 1 can be omitted, the expansion bag 1 is a generalized environmental water body, and the expansion bag has the obvious advantages that the installation space of the buoyancy regulator is greatly saved, and unnecessary external oil bags are reduced, but the expansion bag has the defects that the internal liquid chamber 6 is easy to pollute and rust related parts due to the fact that water of a natural water body is sucked, the related control difficulty is increased, the reliability of the system is reduced, and the expansion bag is particularly not suitable for being applied to a platform which stays underwater for a long time, and if related application is to be realized, special designs such as biological prevention, pollution prevention, rust prevention and the like need to be carried out.
The adjustment accuracy of the buoyancy regulator depends on the accuracy of the non-contact displacement sensor and the adjustment control response time of the adjustment execution system.
The innovation point of the scheme is that the floating rodless piston 5 is ingeniously pushed to move by applying the gas pressure in the closed gas chamber space, and the buoyancy adjusting control is realized by a method of measuring the displacement of the piston 5 by a non-contact displacement sensor and indirectly calculating the buoyancy adjusting size, so that all buoyancy adjusting schemes deduced in all forms based on the principle are in the patent protection range.
The use method of the floating piston type buoyancy regulator comprises the steps that when the regulating medium is hydraulic oil, the expansion bag is a rubber oil bag, and when the regulating medium is an environmental water body, the expansion bag is a generalized environmental water body. So that according to the difference of adjusting medium and environment liquid, select more suitable outside liquid storage space, when adjusting medium is the same with the environment water, transfer the liquid and the environment water of the withstand voltage cabin of watertight and exchange, can simplify the structure more, when adjusting medium and environment water inconsistent, the outside rubber oil pocket that adopts can adjust the medium in confined space, avoids taking place to leak the pollution.
In the embodiment, the laser displacement sensor is in a model number of LK-G80, and the buoyancy adjusting controller is in a model number of 6ES7288-1SR20-0AA 1.
The above embodiments should not limit the present invention in any way, and all technical solutions obtained by using equivalent alternatives or equivalent transformations fall within the protection scope of the present invention.
