The long-shaft pump comprises a bailer vehicle (110), a long shaft (120), a bearing (130), a transmission device (140) and an electric motor (150). The transmission device comprises a planetary gearbox (141), an orthogonal shaft gearbox (142) and a frequency converter (143); one end of the long shaft (120) successively passes through the bearing (130), the planetary gearbox (141), the orthogonal shaft gearbox (142) and the frequency converter (143), so as to be in transmission connection with a drive shaft of the electric motor (150); and the bailer vehicle (110) comprises a cylindrical base (112) and at least three blades (111) distributed on the surface of the cylindrical base (112) in an annular array radially extending from the center of the long shaft. Two adjacent blades and the surface of the cylindrical base forms a bailer capable of bailing water from a lower water side of a channel to a higher water side of the channel. The pump station (200) comprises a pump station foundation (210), several equipment rooms (231) transversely distributed at intervals and constructed on the pump station foundation (210), and two ends of the long shaft (120) of the bailer-type long-shaft pump (100) are supported on side walls of two adjacent equipment rooms. The bailer-type long-shaft pump achieve large water flow and low lift, the pump station is space-saving, has shorter construction cycle, and reduces investment and operation costs.

An equipment monitoring system preferably includes an electronic control device, a controller area network bus wiring harness (CAN BUS) and a plurality of sensors. The electronic control device preferably includes a software program for receiving input from the plurality of sensors. The CAN BUS wiring harness provides an interface between the electronic control device and the plurality of sensors. The plurality of sensors include at least one oil temperature sensor, at least one fluid pressure sensor, at least one vibration sensor, at least one speed sensor, a moisture sensor vacuum sensor and an exhaust air temperature sensor. The software program monitors the plurality of sensors. If the operating limit of one of the plurality of sensors is exceeded, the electronic control device sets off some type of alarm. The electronic control device preferably wirelessly transmits the data received from the sensor to a remote device.

A sewer cleaning device has a rinsing hose, to which pressurized water is applied, which is stored on an assigned storage reel and which passes through a transportation apparatus adjacent to the storage reel. A manner of operating, which protects the rinsing hose, is achieved by providing a reel arrangement, around which the rinsing hose is wrapped at least once, having two redirection reels arranged laterally adjacent to one another in the radial direction, which are offset in relation to one another in the axial direction by at least the thickness of the rinsing hose and of which at least one redirection reel is arranged tilted about an axis of symmetry, which perpendicularly intersects the axes of the two redirection reels, so that during each complete wrap around the reel arrangement forming the transportation apparatus by the rinsing hose, a pitch of the path assigned to the rinsing hose results.

A boom hose apparatus for a material collection vehicle includes a telescoping boom assembly and a hose assembly supported by the boom assembly. The boom assembly includes a plurality of telescoping conduits. A flexible hose is received through the telescoping conduits and can slidably extend from, or retract into, the conduits independently from the telescoping of the conduits.

A large bore mobile vacuum system is used with special large bore vacuum adapters to enable a method and system for cleaning ground tanks used to store wastewater. The ground tank cleaning method and system may be safer and more efficient that conventional methods by enabling a human operator to physically remain outside of the ground tank, while preventing the contents of the ground tank from being exposed to the environment during the ground tank cleaning.

In a sewer cleaning vehicle is provided having a container for the water required for cleaning the sewer and/or the sludge obtained during cleaning of the sewer, and an extension arm which is liftable and lowerable and/or rotatable about a vertical axis and which is accommodated on the container for the manipulation of a flushing hose which can be supplied with compressed water and which can be inserted into the sewer. A suction hose with a suction draft can be lowered into the sewer. At least one further working device which is provided for working the sewer and which can be manipulated by the extension arm is carried along on the vehicle and can be loosely accommodated on an associated retaining device provided on the vehicle side and can releasably be coupled to the extension arm when required by an associated coupling device.

A pump-storage device includes a tank, a treatment container, and a vacuum pump. The treatment container includes a first chamber in communication with an inlet. The first chamber includes a bottom wall having a first valve intercommunicated with a second chamber. The second chamber includes a bottom wall having a second valve. The treatment container includes a first control valve having a first duct in communication with the first chamber, a second duct in communication with the second chamber, and a third duct in communication with the tank. The treatment container includes an actuation cylinder for actuating an actuation rod to extend or retract. A first valve plate and a second valve plate are mounted on the actuation rod for controlling opening and closing of the first valve and the second valve. The treatment container includes a second control valve in communication with the first chamber and the vacuum pump.

A combination vehicle (10) for cleaning a sewer includes a water jetting system (12) with a frame (34) mounted to a first end (38) of the vehicle (10) and horizontally spanning substantially the width thereof, and a slide carriage (36) operatively engaged with the frame (34) and slideable therealong. A hose reel frame (28) pivotally connects to the slide carriage (36) and is pivotal about a vertical axis, and supports a hose reel (30) that is rotatable about a horizontal axis and configured to support a hose (32). The hose (32) operatively connects to a water jetting source (46) to supply pressurized water for use in cleaning the sewer. A controller (44) operatively connects to the hose reel frame (28) and is operable to move the slide carriage (36) along the frame (34), and also to pivot the hose reel frame (28) relative to the vertical axis, thereby to enhance safety and maneuverability in locating the hose (32) in a desired position for cleaning a sewer.
