Definitions
- the invention relates to a machine that can be filled with a gas.
- the invention further relates to a method for monitoring and / or checking a machine.
- Machines such as hydrogen-cooled generators or other gas-fueled machines are designed so that inspection inside the machine is not possible as long as the machine is filled with hydrogen or gas. Therefore, sampling of particles on the surface inside the machine is currently difficult or scarcely possible.
- several steps are required to remove the gas from the engine.
- the hydrogen must be drained from the machine and then rinsed with an inert gas, such as carbon dioxide or argon. After flushing with the inert gas, the generator is filled with air. After filling with air, the generator is walkable and can be checked.
- an inert gas such as carbon dioxide or argon. After flushing with the inert gas, the generator is filled with air. After filling with air, the generator is walkable and can be checked.
- this process takes a comparatively long time for large generators. Experience shows that such an implementation of this process can take more than eight hours.
- the invention begins, whose object is to provide a machine and a method with which an inspection can be carried out quickly.
- a machine which can be filled with a gas, with a housing, wherein a first space is arranged on the housing, wherein between the housing and the first space a first flap is arranged, which forms a fluidic connection between the housing and a second space disposed on the first space, wherein between the first and the second space, a second flap is arranged, which establishes a fluidic connection between the first space and the second space, wherein a monitoring device is provided for checking in the housing.
- the operable flying robot formed from outside as a monitoring device can be moved freely via a remote control in the first room, in the second room and in the generator. This can be done via a radio remote control or similar transmission facilities.
- the object directed to the method is achieved by a method for monitoring and / or checking a machine that can be filled with gas, wherein a remote control bare monitoring device is moved via a lock system in the interior of the machine.
- the invention is based on the aspect that a sluice system is arranged on the machine in order to avoid a complete rinsing of the generator or of the machine.
- the lock system can be attached to a manhole cover of a generator, in particular a foreign generator.
- it is proposed to introduce a monitoring device into the hydrogen-filled generator with the lock system in order to carry out a monitoring or sampling.
- the lock system comprises a first space, which is fluidically connected via a flap to the interior of the generator. Furthermore, the lock system comprises a second space, which is connectable via a second flap with the first space. Finally, the second space comprises an outer flap, via which the monitoring device can be introduced. Inlets and outlets allow the first room and the second room to be filled with air, inert gas or hydrogen.
- An essential idea of the invention is that the monitoring device is arranged in the first space with the first flap and second flap closed and after the first space is filled with the hydrogen which is in the generator and also has the same pressure, the first flap opens and the monitoring device can be moved into the interior of the generator.
- first space and the second space are formed with an exhaust pipe to suck the located in the first room or in the second room gases.
- FIG. 1 shows a schematic overview of the machine.
- the machine is designed, for example, as a generator 1 and comprises a housing 2, wherein hydrogen is contained within the housing 2.
- a lock system 3 is arranged via a connection 4.
- the lock system 3 comprises a first space 5 and a second space 6.
- the first space 5 can be fluidly connected to the interior 8 of the generator 1 via a flap 7. By opening the first flap 7, a fluidic connection between the first space 5 and the interior of the generator 8 is made possible.
- the first space 5 is also formed with a first feed line 9.
- This first supply line 9 comprises three sub-feed lines, which are provided with valves.
- the first supply line comprises a first sub-feed line 10 with a first sub-valve 11. Hydrogen can enter the first space 5 via the first sub-valve 11 and the first sub-feed line 10.
- the first supply line 9 is also fluidly connected to a second sub-line 12 and a second sub-valve 13. Through the second sub-line 12, air can flow into the first space 5. Furthermore, the first supply line 9 is connected to a third sub-feed line 14 and a third sub-valve 15. By the third sub-line 14 carbon dioxide (C0 2 ) can get into the first room.
- the first space 5 is also connected to an exhaust pipe 16 in which an exhaust valve 17 is arranged.
- About the first Exhaust pipe can flow out of the gas in the first space.
- the second chamber 6 comprises a second supply line 19.
- the second supply line 19 comprises a fourth sub-feed 20 with a fourth sub-valve 21.
- the second feed line 19 comprises a fifth supply line 22 with a fifth sub-valve 23.
- Carbon dioxide (C0 2 ) can enter the second space 6 via the fifth sub-line 22.
- the second space 6 further comprises a second exhaust pipe 24 with a second exhaust valve 25 via the second exhaust pipe 24, the gas in the second space 6 can flow out. Via a third flap 26, the lock system. 3
- the first space 5 and the second space 6 are arranged one behind the other and formed pressure-proof and gas-tight.
- a monitoring device in the form of a radio-controlled flying robot 27 can now be introduced into the second space 6.
- the third flap 26 must first be opened and the second flap 18 and the first flap 7 closed.
- the flying robot 27 may be designed as a small helicopter and equipped with a video camera, a headlight and gripping tools.
- transmitting and receiving antennas are mounted on the robot, in the generator 1 and in the first room 5 and in the second room 6.
- the lock system and the monitoring device are now designed such that the monitoring system can fly into the hydrogen-filled generator.
- the robot after the robot has been introduced into the second space 6, the third flap 26 must be closed. Subsequently, the second space 6 is purged with inert gas such as C0 2 and then filled with air.
- the fourth sub-valve 21 and the fifth sub-valve 23 are opened and closed. Thereafter, the robot can be flown by opening the second flap 18 in the first space 5. After closing the second flap 18, the first space is then flushed again with inert gas such as C0 2 and then filled with hydrogen. In this case, the hydrogen in the first space 5 is brought to the same pressure, which also prevails in the interior 8 of the generator 1. Subsequently, the first flap 7 can be opened and the robot can be moved into the interior of the generator 8.
- buoyancy of the helicopter must be adapted to the gas density in the interior of the generator 8.
- any accessible locations can now be approached in the interior of the generator 8, to bspw.
