Underwater equipment carrier and device for working or examining a sole

The present invention relates to an underwater device carrier for use on a sole of a body of water according to the preamble of claim 1 and to an apparatus for processing or examining a sole of a body of water with a corresponding underwater device carrier. The invention further relates to a use of such a device for processing and / or examining a sole of a body of water.

A generic underwater equipment carrier, equipped with appropriate equipment, in particular for the rehabilitation of waters can be used. It is known per se to provide such an underwater device carrier with a self-propelled drive, which comprises two shafts, wherein on one lateral surface of each of these shafts there is in each case one worm for propelling power. is arranged on the sole. As a result, the underwater equipment carrier can be maneuvered, in particular, on a muddy sole without the need for a complex cable pulling device.

Known underwater equipment carriers of the type described have the disadvantage that it is not easy to control how deep the underwater equipment carrier penetrates into the sole with said waves. This can entail that either the snails do not penetrate deep enough into a subsoil of the corresponding water body to generate sufficient propulsion, or that the underwater equipment carrier sinks too deep with the waves and thereby prevents a movement of the underwater equipment carrier by a too high resistance becomes.

The invention is therefore an object of the invention to develop a corresponding underwater equipment carrier, which overcomes the above disadvantage and can easily hold in a precisely controllable depth relative to the sole, so that the screws penetrate deep enough, but not too deep into the sole , The invention is further based on the object to develop a corresponding device for processing or examining a sole of a body of water and to propose an advantageous use of such a device for processing and / or examining a sole of a body of water.

This object is achieved by a Unterwassergeräteträger with the characterizing features of the main claim in conjunction with the features of the preamble of the main claim and by an apparatus having the features of claim 9 and a use with the features of the claim 22. Advantageous embodiments and further developments of the invention will become apparent with the features of the subclaims.

Due to the fact that the waves themselves are designed as buoyancy bodies of the underwater equipment carrier whose buoyancy in water exceeds their own weight in absolute terms, a resultant of buoyancy and gravitational force reacts very sensitively to immersion of the waves in an area of increasing density. The result of this is that the sinking of the underwater implement carrier due to the density gradient normally occurring at a bottom of a body of water only and only takes place until the waves rest on the sole and the worms serving as drive worms are engaged with the sole in such a way that movement of the worm Unterwassergeräteträgers is easily possible by the self-propelled. Under normal conditions, the typically unmanned underwater implement carrier is then completely below a water surface of the corresponding body of water.

The waves mentioned are arranged in preferred embodiments of the invention on two sides of the Unterwassergerä- teträgers and in each case in the longitudinal direction of the underwater device carrier oriented to ensure a stable position of the underwater device carrier on the sole. The screws of the two opposing shafts are preferably designed as opposing spirals, so over this

Waves a resultant propulsion force can be generated, which corresponds as far as possible to an axis of symmetry of the underwater device carrier. The waves can be made for example of metal or plastic, so in each case one with the screws Made of metal or plastic shaft jacket.

A typical embodiment of the invention provides that each of the waves through at least one at a

End of the shaft or motor arranged in the shaft is driven. An arrangement of the respective motor outside the shaft is particularly advantageous because then the waves serving as buoyancy bodies can be designed particularly simply.

In a particularly simple embodiment of the invention, the waves, which are designed, for example, as simple hollow shafts, each have at least one fixed buoyancy tank. Alternatively or additionally, the waves can also have at least one taring tank, which can be filled more or less with ballast, for example water, in order to adjust the underwater equipment carrier - depending on the placement of the underwater device carrier and sole properties - and adjust a penetration depth into the sole. Of course, with filled taring tanks, the specific gravity of the waves, which are themselves designed as floats, can also be higher than that of water.

A particularly advantageous embodiment provides that the waves are frictionally mounted between two thrust bearings, typically by flansch- o- coupling-like connections. Then you can

Shafts are easily replaced, whereby the underwater carrier can be easily adapted to different environmental conditions. For example, waves that are to be exchanged can have different volumes and masses and therefore different buoyancy properties as well as different lely have executed screws with different pitches or tread depths. Alternatively, the shafts can also be mounted by means of flange connections between the corresponding abutments, which additionally form a positive connection, but are also designed so that it is possible to remove the shafts when abutments remain mounted.

In addition to the named waves, in further developments of the invention, at least one further buoyant body arranged above the waves can be provided in order to ensure overall greater buoyancy and / or better Triiritninöglichkeiten. Accordingly, the at least one further buoyant body can be designed as a taring tank or else only as an optionally replaceable fixed buoyancy tank. Such a further buoyant body allows a more flexible use of the underwater device carrier with various additional devices which lead to a total mass which varies over a relatively large interval.

Based on a type of underwater device described above, an advantageous device for processing or examining a sole of a body of water can be realized. For example, the body of water may be a lake, a pond or flowing water.

An advantageous embodiment of such a device provides that the underwater device carrier carries a pressure measuring device for determining a water depth, that is to say for determining a depth of the underwater device carrier under a water surface. This may be, for example, a piezoelectric pressure gauge.

The underwater equipment carrier may also be connected to a receiver of a satellite-based navigation system, that is to say for example with a GPS receiver, wherein the receiver is held floating on the water surface above the underwater equipment carrier. For this purpose, the receiver may be carried by a float, which is connected by a rope to the underwater equipment carrier. Such a cable can in turn be combined with a length compensating device which ensures that the receiver always remains above the underwater implement carrier, for example by means of a spring-loaded winch. By embodiments of this kind, a current position of the underwater equipment carrier can be determined accurately in a simple manner.

For determining a location of the underwater implement carrier, the device may also comprise a tachometer which cooperates with a reflector which is connected to the underwater device carrier and is kept floating on the water surface above the underwater device carrier. The reflector can be, for example, a prism supported by a float or a plurality of such prisms, wherein the float can again be connected to the underwater device support via a rope that may be combined with a length compensation.

The underwater equipment carrier may also be equipped with at least one underwater camera for sole examination and / or navigation. A preferred embodiment of the device provides that the underwater equipment carrier is equipped with at least one pump for sucking material from the sole. This pump can be placed between the two branches, where it is well protected and where the rotating screws can assist in pumping out, in particular by loosening up the sole. In this embodiment, the device can be used, for example, for desliming a watercourse floor.

It may be advantageous to design the underwater implement carrier with cutters for loosening the sole. These may be e.g. on the. Be arranged Schncs-, preferably at a front end of the respective screw, wherein the cutting devices are preferably oriented perpendicular to a course of the worm gear. Also, such a cutting device may be arranged in front of a suction head of a pump in order to facilitate a suction of material by the loosening.

Alternatively or additionally, the underwater implement carrier can also be equipped with a device for injecting material into the sole and / or for applying material over the sole. Then the device can serve in particular for sediment conditioning or in the case of the second alternative for precipitation of suspended solids by flocculation. By means of said device, both additional substances can be introduced into the sole as well as previously sucked off parts of the sole - for rearrangement and / or after a modification - are returned to the sole. Preferably, said means for injecting or discharging material comprises a pump carried by the submersible for generating or increasing an injection pressure. This may be unnecessary in an advantageous manner, to convey the material to be introduced already under high pressure to the underwater equipment carrier.

Alternatively or additionally, said injecting means may comprise a mixing module carried by the underwater implement carrier for bringing together at least two components of the injected or discharged material. This may be advantageous, in particular, when the material to be injected or to be applied over the sole consists of a mixture which, when mixed, is difficult to convey to the underwater equipment carrier, for example because it hardens rapidly.

Finally, in an advantageous embodiment of the invention, said device may comprise injection nozzles which are arranged in the immediate vicinity of the shafts and / or on a jib oriented transversely to the shafts. An arrangement in the immediate vicinity of the waves can have the advantage that the material is injected where the screws lead to a loosening of the sole. In turn, by using a cantilever oriented transversely to the shafts, a large-area treatment of the sole can be achieved in a simple manner. It is also possible for a plurality of nozzles or booms to be arranged one behind the other in order to enable injection or discharge of material over the sole with different injection materials in one operation. An advantageous embodiment of the invention provides that the device is designed as a modular system in which the underwater equipment carrier can be equipped by a simple exchange of modules with various nen from a group of several or all of the previously mentioned devices.

The device may comprise a supply and / or disposal unit which has at least one line connection floating in a first section from the underwater equipment carrier to the water surface and in a second section along the water surface continuing to a supply and / or disposal station. This line connection may comprise multiple lines, each of which is e.g. the removal of pumped-off sole material, the supply of injectable into the sole or over the sole auszubringendem material, a supply or discharge of ballast or a power supply of the underwater device carrier can serve. Such a line may in particular carry compressed air, hydraulic fluid or electric current. The conduit connection may also include a tube or a preferably flexible tube that is gas-filled and that maintains the conduit connection in the second portion of the conduit connection to the water surface. This hose or tube may in particular be air-filled and, for example, additionally serve as a compressed air supply.

An advantageous method for processing and / or examining a bottom of a body of water results from the use of a device of the type described. The underwater device carrier, which is typically completely submerged and resting on the sole, can be driven by rotating the shafts. and carried over the sole, carried by the underwater equipment carrier extracted soil material or sediment-water mixture to the water surface and / or transported a material for soil treatment or flocculation from the water surface from the underwater equipment carrier and from there to the sole or above Sole into the water can be injected. As a result, water sediments, for example, can be relocated, solidified or selectively sucked off, wherein the underwater equipment carrier can advantageously be used largely independently of a water depth or working depth.

The screws can be realized by helical metal or plastic profiles in a form known by screw conveyors on the waves, which are preferably driven by one or in pairs arranged waterproof drive units. The drive units may each be integrated in a cylindrical base body of the shafts, a torque then being e.g. via internal planetary gear can be transmitted to the shafts, or arranged frontally so that there are each unilaterally or bilaterally fixed drive heads, between which the shaft is braced, the torque then z. can be transmitted to the shaft via sprockets. In this case, a particularly easy interchangeability of the waves with the screws results. A

The speed of the shafts may be adjustable, for example, via frequency converters and / or by geared motors. At a speed that is the same on both sides, the underwater implement carrier is moved forwards or backwards in a straight line, while the direction is determined by one-sided operation or operation with different rotational speeds can be changed. By an opposite direction of rotation or conveying direction of the waves with the screws, the sediment can be loosened and pressed, for example, in the direction of a suction pump.

By using modular assemblies, the device described can be used for various tasks, e.g. for the conditioning of water sediments, for precipitation or flocculation within the water body, e.g. a flocculation of sediment or suspended matter horizons above the sediment, for solidification of sediment surfaces, selective degradation of water sediments by extractors, or for initial storage of water sediments. A combination of these applications is possible.

Embodiments of the invention are described below with reference to Figures 1 to 12. It shows

12 is a plan view of the water with the underwater equipment carrier of FIG. 11th

In Fig. 1, an underwater equipment carrier with a frame 1 can be seen, which is oriented on two sides respectively in the longitudinal direction of the underwater device carrier and rotatably mounted in the frame 1 waves 2. On one lateral surface of each of these shafts, a respective screw for generating propulsion is arranged on a sole of a body of water, so that the shafts 2 together with motors 3 arranged at each end of the shafts 2 form a self-propelled unit of the underwater device carrier.

The waves 2, which may be made of metal or plastic, are each designed as a buoyant body whose buoyancy in water their own weight in terms of amount surpasses. In the illustrated here simple embodiment of the invention, the waves thereby each form a fixed buoyancy tank, the thereby it is realized that the shafts 2 are hollow and sealed. In a modification of the invention, the shafts may additionally or alternatively have a taring tank with which the underwater implement carrier can be trimmed.

Between the two shafts 2, a pump 4 designed as a mud pump can be seen. With this pump 4, material can be sucked out of a bottom of a body of water on which the underwater device carrier is inserted. Before the pump 4, a rinsing pump 5 is arranged, which belongs to an underwater nozzle system or jet system and with which hydraulic shear forces in the region of a suction head of the pump 4 can be registered in the sole in order to support sediment loosening.

2, the same underwater equipment carrier is shown in a side view, wherein recurring features here and in the following figures are again provided with the same reference numerals and no longer need to be described in detail. In FIG. 2, one of two further buoyancy bodies 6 arranged above the shafts 2 can additionally be seen, which are designed as taring tanks and with which the underwater equipment carrier can be trimmed and, in particular, adapted to different loads. For this purpose, the buoyant body 6 can be filled with ballast water or emptied by compressed air. Alternatively, the buoyancy bodies 6 could also be designed as fixed buoyancy tanks, in particular if the waves already have two taring tanks. With the buoyancy tanks, the buoyancy of the underwater equipment carrier can be adjusted manually or automatically so that the underwater equipment carrier is submerged on a waterbed or after completion of a Sole treatment reappears again to a water surface and depending on a density difference between open water and riverbed rest on the riverbed and can be moved over this.

FIG. 3 shows the same underwater equipment carrier in a front view, whereby recurring features are again provided with the same reference numerals.

One of the shafts 2 with two of the motors 3 is shown in Fig. 4 as SchnittZeichnung. There it can be seen that the shaft 2 is mounted kraftschlüssicr between two thrust bearings by means of bearings, which are designed as the abutment flange. This allows a very simple expansion of the shaft 2, for example, for the purpose of replacement by a different equivalent replacement shaft. Finally, in each case a gear 7 can be seen between the motors 3 and the respective thrust bearing, which serves to reduce the rotational speed of the corresponding motor 3.

A different type of shaft 2 for use in a similar underwater equipment carrier is shown in FIG. In this wave 2, which is also designed as a buoyancy body whose buoyancy in water exceeds its own weight in terms of amount, a hub motor 8 is disposed within the shaft 2, with which the shaft 2 can be driven. Also, this shaft 2 is frictionally mounted by a flange or coupling-like connection between two thrust bearings, wherein the abutment are connected to bearing pin 9, which in turn are mounted in the frame 1 of the corresponding underwater device carrier. Fig. 6 shows an apparatus for processing or examining a sole 10 of a body comprising an underwater device carrier of the type described above. This is completely below a water surface 11 and rests on the sole 10, over which it is moved by driving the shafts 2 by means of the screws. Here, the underwater equipment carrier on a pressure measuring device 12 for determining a water depth, which is designed as a piezoelectric pressure cell and is connected via a data line 13 with a arranged on a float 14 transmitting station. This float 14 also carries a receiver 15 of a GPS system with which a current location of the underwater gyroscope carrier can be determined. For this purpose, the receiver 15 is connected via a cable to the underwater device carrier, wherein a length compensation ensures that this rope is taut at above the device carrier floating float 14. With the transmitter already mentioned, the specific location of the underwater device carrier can be transmitted wirelessly to a system control together with the water depth. Of course, instead of a wireless data transmission, a signal cable can also be used.

Figure 7 shows a plan view of a body of water whose sole 10 is being treated with an underwater implement of the type described, again holding a float 14 above the underwater implement in the manner previously described. In a modification of the embodiment described above, this float 14 carries a prism instead of a GPS receiver, which allows a location of the underwater device carrier by means of a arranged on a bank of the water tachymeter 16, the one for this purpose Laser beam 17 directed to the arranged on the float 14 prism. The tachymeter 16 and the prism connected via a cable tension to the underwater equipment carrier and floating above it forms a self-tracking tachymetric surveying system by means of which the location of the underwater equipment carrier can be detected in a local coordinate system.

By determining the depth of water with the pressure measuring device 12 and the position determination of the underwater device carrier with a GPS, as in the embodiment described with reference to FIG. 6, or with the tachymetric surveying system described with reference to FIG. 7, the underwater device carrier can be guided, for example Basis of existing digital water measurement data. In addition, the underwater equipment carrier can be equipped with an underwater camera, which can serve not only for sole examination, but also for navigation. Then a guide of the submerged device underwater with the underwater camera or several underwater cameras can be supported.

8 shows the underwater implement carrier of FIGS. 1 to 3 with an additionally mounted device for injecting material into the sole 10 and / or for dispensing material over the sole 10, this device comprising injection nozzles 17 arranged transversely to one another to the waves 2 oriented boom 18 are arranged. A front view of the underwater device carrier with this device is shown in FIG. 9, a side view of the corresponding underwater device carrier in FIG. 10. Additionally recognizable is one of the water surface 11th from the underwater equipment carrier leading supply line 19. The said device, which comprises the metering comb designed as a jib 18 with the injection nozzles 17 and is fed through the supply line allows suspended mixtures of active substances such as solutions or gases (eg oxygen or air) areally or selectively be applied to a sediment surface at the sole 10 or injected into the sediment by means of the injection nozzles 17. The boom 18 has laterally projecting arms, which allow a distribution of the active ingredients over a large width. The underwater equipment carrier can carry one or more pressure hearing pumps, especially for larger water supply. reduce the Er.er- ing need for the supply of the material to be injected and / or increase the pressure for injection into the sediment. In addition, the underwater equipment carrier may carry a mixing module for combining active substances in a multi-component application shortly before deployment. By also possible arrangement of several corresponding devices, eg front and rear, different active substances can be applied simultaneously in parallel.

The device for injecting material into the sole 10 equipped with the arm 18 in the exemplary embodiment from FIGS. 8 to 10 may alternatively also be designed such that an entry of the active substances can take place directly in the region of the shafts 2 with the drive screws, so that the active ingredients are incorporated via a screw movement of the screws on the waves 2 in the sediment. With the device shown in FIGS. 8 to 10, it is also possible to apply active substances into the body of water above the sole 10, for example in order to flocculate and precipitate suspended cloud horizons above the sediment and the sole 10.

11 shows a cross section through a body of water with a water surface 11 and a sole 10, in which a device with an underwater device carrier of the type described is used. This device further comprises a supply and disposal station 20 with a line connection 21, which in a first section of the underwater equipment carrier to a connection station 22 on the water surface 11 and in a second section long the water surface 11 floating on to the supply and disposal station 20th leads. The supply and disposal station 20 could of course also be arranged to float. The line connection 21 comprises in the second section a support hose which is filled with air and holds the line connection there to the water surface 11. A likewise enclosed by the line connection 21 pressure hose for pumped sediment-water mixture is spirally guided around this support hose, but could also be connected in other ways form-fitting and flexible with the support hose. The line connection 21 comprises in particular a compressed air hose for emptying the buoyancy tanks of the buoyancy bodies 6 as well as power and control cables. It may also include hydraulic hoses, provided that hydraulic drives are provided. The power and control cables and, if applicable, hydraulic hoses can be used for the operation and control of the motors 3 and other units with which the underwater equipment carrier is fitted. The line connection 21 comprises furthermore, at least one pressure hose with which either active substances, for example for sediment conditioning or flocculation, are conveyed from the supply and disposal station 20 to the underwater equipment carrier and / or conveyed extracted deep water or sediment-water mixture from the underwater equipment carrier to the supply and disposal station 20 becomes.

In the case of the device shown in FIGS. 11 and 12, the underwater device carrier is equipped in particular with the pump 4, which is e.g. may be designed as a mud pump and with which the sediment is sucked from the sole 10 as a sediment-water mixture and conveyed to the supply and disposal station 20 via said pressure hose. The sediments can be extracted layer by layer and selectively in depth and location. By rotating the screws with the shafts 2, the sediment can additionally be loosened up and fed to the underwater mud pumps (pump 4, flushing pump 5) arranged centrally between the shafts 2, without any sediment being whirled up. In addition, perpendicular to a screw flight of the screws on the shafts 2, preferably in the region of a screw crown and at the level of the suction head of the pump 4, cutting units can be mounted to assist additional loosening of settled sediments and / or tearing or cutting of sediment deposits such as white roots can. The suction head of the pump 4 can also be designed adjustable in height, for example mechanically or hydraulically.

In order to allow precise maneuvering with the unmanned underwater implement carrier, the speed of the shafts 2 can be adjusted with the screws via frequency converters and / or by a corresponding design the transmission 7 (see Fig. 4) are changed continuously. The motors 3 can thus be designed in particular as, for example, electric or hydraulic geared motors.

Since the shafts 2 are easily replaceable, the underwater equipment carrier can be equipped with screws of different pitch and range. An optimal adaptation to a density, viscosity and shear strength of the sole 10 then takes place via the different pitch, wherein a high pitch is typically selected for a soft sole 10 and a low pitch for a solid sole 10. About a Gangwεite the snails, a travel speed of the underwater equipment carrier can be influenced.

A device of the type described here can be used for processing and / or examining a sole 10 of different waters, in particular for work on the bottom 10 of natural waters (eg lakes, ponds, running waters), artificial waters (eg water reservoirs, reservoirs or reservoirs) Fish breeding facilities) or technical facilities (eg storage tanks or sewage treatment plants).
