摘要:
A hydrodynamic nozzle for the cleaning of pipes and channels exhibits a distribution chamber (7), joining to the pressurized water-entrance opening (4), wherein the pressurized water-discharge opening (5a, 5b) join into the distribution chamber (7) through channels (6a and 6b). The distribution chamber (7) exhibits a cone-shaped water subdivider (8), to which a defined radius (r1) follows, wherein the curvature of the radius (r1) is opposite to that of the pressurized water-entrance opening (4). The channels (6a and 6b) are merging tangentially at this radius (r1). Furthermore, the nozzle body (1) can be subdivided into an upper part (2) and a lower part (3), and can exhibit a separate form element (14), which forms the water subdivider (8) and the radius (r1), in the lower part (3). The degree of effectiveness is substantially increased with the nozzle according to the invention and thus the axial pressure of the exiting beam of liquid and the cleaning effect is substantially increased.
摘要:
A hydrodynamic tool for the cleaning of pipes and channels exhibits a pressurized water-entry inlet opening (2) connected to pressurized water-discharge outlet openings (4) through water guide channels (3). The water guide channels (3) are continuously connected to the pressurized water-entry inlet opening (2) with a hose connection (2a). The water guide channels (3) exhibit a largest possible deflection radius (r) and partially converge into one another. At least two water guide channels (3) rest with the innermost point of the diameter (d.sub.W1) at the center point (M) and with their outermost point of the diameter (d.sub.W1) at the outer diameter (d.sub.E) of the pressurized water-entry inlet opening (2). The water guide channels (3), corresponding to the arrangement of the pressurized water-discharge outlet openings (4), are either merging into the end of the deflection radius (r) or into the straight line region (3.G) and in an angle (.alpha.) to the respective pressurized water-discharge outlet openings (4).
摘要:
A hydrodynamic apparatus for cleaning channels and for monitoring channels is provided for pipes and channels. A disadvantage of all conventional bottom floor cleaners, flushing heads, and channel-cleaning nozzles is that during the cleaning process no observation and determination of the soiling state or, respectively, of the cleaning state of the channel and no recognition of damaged areas in the channel is possible. According to the invention, a monitoring unit (6) is installed selectively in or at the channel-cleaning apparatus. For this purpose, for example, a hollow space (11) is furnished at the bottom floor cleaner (S), wherein the monitoring unit (6) is partly integrated into the hollow space (11). The monitoring unit (6) exhibits a camera module (7) or two camera modules (7a and 7b). A video emitter (15) is coordinated to each camera module (7). The transmission to a video receiver (V) is performed without cable wireless from the video emitter (15). The cleaning process can be followed in a monitor (M). As desired, also ballast material (12) can be filled into the hollow space (11).
