A non-motorized inspection device for inspecting a fluid pipeline, includes a monitoring device capable of generating at least one representation of the pipeline, an inertial unit capable of determining orientation data relating to the inspection device, and a means for preventing distortion of the at least one representation.

A sewer inspection or maintenance system is provided, at least comprising a carrier system, a satellite system which is movable relative to the carrier system, and a guide device coupled to the carrier system, along which the satellite system can be guided during a movement relative to the carrier system. The guide device can be extended or unfolded or rolled out from a stowed position into at least one position of use, so that the effective length of the guide device can be increased.

A drilling apparatus has a work robot mounting a drilling blade and moving inside a main pipe and a photodetector for detecting the contour of an opening image formed on the inner surface of a pipe lining material by illumination light. The opening image is scanned, and a two-dimensional image corresponding to the opening image is generated based on the contour points P0 to P8 detected by the photodetector for display on a display unit. The amount of positional deviation between the center of the two-dimensional image on the display unit and the axial center C of the rotary shaft of the drilling blade is calculated, and the pipe lining material is drilled by moving the drilling blade by the amount of positional deviation in a direction in which the positional deviation is eliminated.

The purpose of the present invention is to provide a highly efficient method for capturing images inside a confined space without the need for direct visual observation by an inspector. Provided is an unmanned aerial vehicle equipped with at least four rotors, a drive device that drives the rotors, a control signal generation circuit that generates a control signal for causing the drive device to drive the rotors, and an imaging camera, wherein said unmanned aerial vehicle is configured to fly within a confined space by driving the rotors while capturing images inside the confined space by means of the imaging camera.

The invention discloses an anti-blocking device for a field channel, a fixed plate which is symmetrical back and forth, and comprises a front and back symmetry fixing plate, the lower end of the fixing plate can be fixed to the two sides of the canal channel of the canal, a transmission box is fixedly connected between the fixed plates on the two sides, a transmission device is arranged in the transmission box, and a cleaning device is arranged on the lower side of the transmission case, the device is simple in structure, a plurality of devices can be arranged on the canal channel, the cleaning efficiency is improved, the device can automatically clean the channel in the canal channel, avoid blockage of the channel after a long time, can collect sundries, and does not need manual cleaning, and the collected sundries are taken out by only human timing.

Provided is a rinsing head for a pipe or sewer inspection system, comprising imaging means arranged at the front end and rinsing means arranged axially behind the imaging means. The rinsing means comprises a number of rinsing nozzles with openings arranged on its lateral surface and spaced apart from each other circumferentially. The rinsing nozzles are connected via to an inlet opening for pressurized water provided at the rear end of the rinsing means. A WLAN module is arranged within the rinsing head and coupled to a camera module of the imaging means operatively. An antenna unit of the WLAN module is arranged axially behind the rinsing nozzles with at least one antenna arranged at least partially radially around the inlet opening for pressurized water. The WLAN module and the antenna unit are adapted to transmit image and/or video data provided by the camera module to a control/display means.
