A drain cleaner including a cable (50) configured to inserted in a drain, a drum (32) supporting the cable, a motor configured to rotate the drum, and a cable feed control mechanism configured to feed the cable in a linear direction. The cable feed mechanism includes a plurality of feed wedges (108) surrounding the cable, a plurality of rollers (112) supported by the feed wedges, and a collar (120) positioned around at least a portion of the plurality of feed wedges and having a cam surface. Each feed wedge has an inclined surface (152). Movement of the collar relative to the plurality of feed wedges causes the cam surface of the collar to engage the inclined surfaces of the plurality of feed wedges to move the plurality of feed wedges radially inward and into engagement with the cable.

Bereitgestellt wird eine Rohrinspektions- und/oder Wartungseinrichtung für ein Rohrinspektions- und/oder Wartungssystem, aufweisend - ein Gehäuse, - eine im Gehäuse angeordnete elektrische und/oder elektronische Komponente, - einen im Gehäuse angeordneten und mit der elektrischen und/oder elektronischen Komponente gekoppelten Akkumulator, wobei - die elektrische / elektronische Komponente und der Akkumulator fluid- und gasdicht in dem Gehäuse angeordnet sind, und - der Akkumulator mit einer Ladeeinrichtung gekoppelt ist, die ebenfalls fluid- und gasdicht in dem Gehäuse angeordnet ist, wobei die Ladeeinrichtung angepasst ist - mit einer außerhalb des Gehäuses anordenbaren Ladeeinheit zusammenzuwirken, um elektrische Energie drahtlos von der Ladeeinheit an die Ladeeinrichtung zu übertragen, und - mit der übertragenen elektrischen Energie zumindest teileweise den Akkumulator aufzuladen.
Bereit gestellt werden ferner ein Rohrinspektions- und/oder Wartungssystem, aufweisend eine erfindungsgemäße Rohrinspektions- und/oder Wartungseinrichtung, eine Ladeeinheit und ein Energieversorgungsmodul für eine erfindungsgemäße Rohrinspektions- und/oder Wartungseinrichtung.
摘要:
A nozzle assembly comprises a hollow nozzle body having a central bore and a plurality of ports extending through the body from the central bore; and a switching valve cartridge disposed in the central bore that directs fluid flow to ports upon application of fluid flow above a predetermined threshold to the inlet and direct fluid flow to different ports upon fluid flow having subsequently dropped below the predetermined threshold and then exceeding the predetermined threshold. The cartridge comprises a cylindrical cartridge case having a front portion and a cup shaped rear portion, a cylindrical poppet slidably disposed within the cup shaped rear portion of the cartridge case, and a biasing member within the cartridge case between the front portion of the case and the poppet urging the poppet away from the front portion of the cartridge case.

An opening/closing device 1 includes a gate 10 that receives a flow of a sewage W, and can fall toward a downstream side of the flow, a fall prevention unit 20b that prevents the gate 10 from falling by supporting the gate 10, a support release unit 22b that releases the support for the gate 10 by the fall prevention unit 20b, a first float 18 that is arranged on the upstream side of the gate 10, and is smaller in specific gravity than the sewage W, a surfacing prevention unit 44 that prevents the first float 18 from surfacing, a second float 16 that is arranged on the upstream side of the gate 10, is arranged above the first float 18, and is smaller in specific gravity than the fluid, and a surfacing-prevention release unit 42 that releases, resulting from surfacing of the second float 16, the prevention of the surfacing of the first float 18 by the surfacing prevention unit 44. Further, the support release unit 22b is activated resulting from surfacing of the first float 18.
