Definitions

  • the invention relates to a lock gate that is at least partially submersible in water or in a body of water, according to the preamble of claim 1.
  • EP 2159330 A1 discloses a lock gate according to this generic term.
  • Lock gates that are at least partially submerged in water or at least partially operated under water are subject to increased requirements. This applies to roller gates of waterways, in particular roller gates of shipping locks, which are usually largely below the water level during operation.
  • Roller doors usually comprise a system of one or more rails arranged at the bottom of the lock trough and of one or more associated carriages, the so-called undercarriages.
  • the undercarriage (s) are connected to the door body and are used to move the roller door between the open position and the closed position.
  • Such a wheel-rail system as a maintenance-intensive assembly can only be inspected and serviced to a very limited extent and with increased effort, especially in the case of a machine device that is immersed in a body of water during operation, for example a lock gate.
  • the informative value of an inspection judgment made under these conditions is therefore generally correspondingly limited.
  • a close-hand inspection of the underwater assembly, for example the undercarriage, with a good view in the dry is not possible. Therefore, wear and damage are often noticed late or even too late, which can lead to a correspondingly high repair effort with corresponding downtimes.
  • the object of the present invention is to develop a sluice gate with a receptacle for an underwater assembly that can be immersed in water during operation so that the wear and tear of the underwater assembly is reduced and there are also improved possibilities for diagnosis and maintenance of the underwater assembly.
  • the lock gate according to the present invention can be at least partially immersed in water or in a body of water during operation, and comprises a receptacle in which an underwater assembly of the lock gate can be arranged.
  • the lock gate is characterized by a hollow cell arranged in the region of the receptacle, which is at least partially open in a lower region, while the lateral and upper regions of the hollow cell are hermetically sealed or can be hermetically sealed.
  • the underwater assembly of the lock gate can be arranged in the hollow cell.
  • the sluice gate can be operated lowered into the body of water, the hollow cell simultaneously remaining air-filled due to its areas which are airtight at the sides and at the top.
  • the underwater assembly which is now operated in the dry, also significantly facilitates diagnosis and maintenance of the underwater assembly and adjacent assemblies. Foreign bodies in the area of the underwater assembly can be detected in good time before they damage the system. This applies in particular when the underwater assembly is a carriage of the lock gate, as is the case according to particularly preferred embodiments of the invention.
  • the lock gate comprises a compressed air device or pump device for draining the hollow cell.
  • the hollow cell can be drained at any time if necessary, while the lock gate remains immersed in the water.
  • the drying process can take place after the lock gate is immersed in the water for the first time, for example, or during the operation of the lock gate if, due to external circumstances, water should have penetrated into the hollow cell.
  • the hollow cell comprises a camera device for remote monitoring and diagnosis of the underwater assembly located in the hollow cell.
  • a camera device for remote monitoring and diagnosis of the underwater assembly located in the hollow cell.
  • the hollow cell comprises a pressure lock device for maintenance personnel to access the hollow cell, while the lock gate is or remains immersed in the water.
  • the pressure lock device is arranged between the hollow cell and an access space which is closed off from the water pressure and which is under atmospheric air pressure, for example a stairwell or a machine room.
  • the hollow cell has a tubular device that can be moved out of the hollow cell beyond the lower open area of the hollow cell.
  • the pipe device is designed so that it can be brought to rest on the bottom of the body of water and, if necessary, can then be drained if necessary.
  • tubular device is to be interpreted broadly and should not be limited to a strictly tubular component as long as the requirement of a jacket surface closed in the lateral circumferential area and the possibility of bringing the lower open end of the device to the bottom of the body of water is fulfilled.
  • This pipe device can thus be moved or extended under water beyond the lower open area of the hollow cell until the lower edge of the pipe device reaches the bottom of the water and comes to rest there. If the installation of the pipe device at the bottom of the body of water is largely watertight, the pipe device can then be drained, which results in a largely dry access to the bottom of the body of water from the hollow cell.
  • the tube device can be hermetically sealed at its upper end with a viewing pane. In this way, after the pipe device has been extended, there is also a largely dry view of the bottom of the body of water.
  • the tubular device is helpful, in particular, for the inspection and, if necessary, maintenance of the rails of a lock gate designed as a roller shutter. This results not only in dry access, for example for maintenance work, to the underwater assembly of the lock gate arranged in the hollow cell, i.e. e.g. to the undercarriage of the lock gate, but also to the rail laid on the floor of the lock trough.
  • condition of the running rail can also be checked directly by hand, any wear and tear can be detected, and the necessary maintenance or repair work can be initiated in good time before major damage occurs to the undercarriage or the rail.
  • the hollow cell has at least one at least partially transparent wall.
  • an optical inspection of the underwater assembly can be carried out in a pressure-neutral manner or without the need for pressure equalization be carried out by maintenance personnel while the lock gate is immersed in the water or is in operation.
  • the maintenance personnel go downstairs to the area of the hollow cell, for example, and can thus observe or control the underwater assembly arranged in the hollow cell during operation through the viewing window under atmospheric pressure conditions.
  • a flushing system for cleaning the underwater assembly is arranged in the hollow cell.
  • the flushing system is preferably remotely controllable and can be observed remotely by means of a camera, for example from the control room.
  • the effect of the flushing system can be viewed, e.g. via remote video monitoring, and checked on the dry undercarriage during operation.
  • the nozzles of the flushing system can be cleaned, adjusted or even exchanged easily and under operating conditions (without having to move the door to a dry dock) as required.
  • stage device is arranged in the hollow cell.
  • the underwater assembly i.e. the undercarriage in the case of a lock gate, can be observed by maintenance personnel in operation and still in the dry.
  • the lock gate is characterized by an essentially vertical extraction shaft which, when the lock gate is submerged, forms a connection between the area of the underwater assembly and the atmosphere.
  • the extraction shaft is designed in such a way that the hollow cell, together with the dry underwater assembly arranged in it, emerges from the lock gate can be removed and placed in the area of the atmosphere above the water level. Otherwise the lock gate remains completely submerged in the water.
  • Fig. 1 shows highly schematically a lock gate 1 designed as a roller door, for example for a shipping lock.
  • the surrounding lock trough 2 is only indicated schematically in all of the figures.
  • the gate 1 can, as indicated by the movement arrow 4, be moved back and forth on a rail device 5 arranged at the bottom of the lock trough 2 in order to either close the lock trough 2 tightly on the respective side of the lock, or the access to the lock trough 2 to open for ships.
  • the lock gate 1 has one or more undercarriages 6, of which only one undercarriage 6 is shown here.
  • Fig. 2 shows how this problem is solved with the aid of the invention in that a hollow cell 7 is provided in the roller door 1, which is at least partially open in a lower area 8, while the side and upper areas or walls are hermetically sealed or lockable are.
  • the undercarriage 6 of the roller door 1 is arranged in the hollow cell 7, and the hollow cell 7 is filled with air under a corresponding excess pressure so that the water is or remains displaced from the hollow cell 7, as a result of which a water level 8 is formed in the lower area of the hollow cell .
  • a window area 11 for example a porthole or a glass floor, can be let in between an access space 9 arranged in the roller door 1, for example a machine room of the lock gate, and the hollow cell 7. Maintenance personnel can then enter the access space 9 (under the normal pressure conditions of the surrounding atmosphere 12) via a stairwell 10, for example, and observe and check the carriage 6 during operation through the window area 11.
  • Fig. 3 shows an embodiment of a lock gate 1, which is additionally equipped with a pressure lock 13 for access by maintenance personnel is equipped in the hollow cell 7.
  • the pressure lock 13 is located between the access room 9, which is accessible via the staircase 10, and the hollow cell 7. Normal atmospheric air pressure conditions prevail in the staircase 10 and in the access room 9, since the access room 9 is connected to the surrounding atmosphere 12 via the staircase 10 stands.
  • the pressure lock 13 is at the same increased air pressure level as the hollow cell 7.
  • the maintenance personnel can now open a connecting door (also not shown) between the pressure lock 13 and the hollow cell 7 and enter the hollow cell 7.
  • Fig. 4 shows very schematically how, with the help of a tubular device 14 which can be extended in the lower region of the hollow cell 7, even the rails 5 arranged on the bottom of the lock trough can be checked partially or completely in the dry and, if necessary, repaired.
  • the pipe device 14 is lowered through the water level 8 to the bottom of the lock trough, and a largely watertight seal between the lower edges of the
  • Pipe device 14 and the corresponding bottom area 15 of the lock trough created. Subsequently, the inner area of the pipe device 15 can be drained or drained, for example by a pump, whereby the corresponding floor area 15 of the lock trough, for example with the section of the rail 5 contained therein, becomes accessible almost dry.
  • the pipe device 14 can be hermetically sealed at the upper end with a disk. Then there is no need to pump out the pipe device 14, in which way at least one visual inspection of the corresponding floor area 15 or the surface of the rail 5 can still be carried out.
  • Fig. 5 shows a variant in which the undercarriage 6 is initially positioned on the rail 5.
  • the variant with the undercarriage 6 initially parked on the rails 5 is currently the most common variant of the assembly of a roller shutter according to the state of the art.
  • the gate body 16 of the lock gate 1 is then floated in and lowered, the hollow cell 7 in the variant according to FIG Fig. 5 is already air-filled in advance.
  • the installation variant according to Fig. 6 differs from the in Fig. 5 variant shown in that the hollow cell 7 in the variant according to Fig. 6 is not pumped out initially, but only after the Gate body 16 is pumped out on the undercarriage 6 or filled with compressed air.
  • Fig. 9 shows an embodiment of a roller door 1, which additionally has a removal shaft 17.
  • the extraction shaft 17 is open at its upper end and runs along the entire vertical extent of the gate body 16, so that the surrounding water is up to the same level as the surrounding water due to the principle of communicating pipes within the extraction shaft 17.
  • a tower compartment 18 is arranged inside the removal shaft 17, which comprises or carries the hollow cell 7. Since the tower compartment 18 and the hollow cell 7 are only open and otherwise closed in the lower area 8, they displace the water from the extraction shaft 17 when the tower compartment 18 with the hollow cell 7 and the undercarriage 6 arranged therein is located in the extraction shaft 17 .
  • the tower compartment 18 is connected to the removal shaft 17 by means of a detachable connecting device 19.
  • the tower compartment 18 with the hollow cell 7 together with the undercarriage 6 arranged therein can be removed from the removal shaft 17 and thus from the gate body 16, in particular for maintenance and repair purposes, without the lock gate 1 having to be removed or placed in a dry dock would have to be.
  • Fig. 10 shows an arrangement of an undercarriage in the hollow cell of a gate body in a possible structural design.
  • the outer, airtight delimitations 20 of the hollow cell 7 and the undercarriage 6 arranged therein can be seen.
  • the undercarriage 6 thus runs, as already explained with reference to the preceding figures, and as in FIG Fig. 10 indicated by the surrounding water 21 with the water level 8 in the area of the hollow cell 7, almost completely in the dry.
