The invention discloses an inner wall loss measuring device for power pipelines, which includes a coiled cylinder group and an insertion sleeve, a detection mechanism is installed in the insertion sleeve, and a catheter is wound and connected to the coiled cylinder group. The detection column and the air bag realize the detection of the change length and change amount of the inner wall of the pipeline. When measuring, the lifting column can be rotated first to drive the sealing sleeve to a suitable position, so that the insertion sleeve can be inserted into power pipes of different diameters. Both can achieve the purpose of normal detection. Once the depression is measured, the values ​​on the pressure measuring device and the distance measuring cylinder will change, so that the change amount and the initial change position can be obtained. After the insertion sleeve passes through the depression, the pressure measurement The values ​​on the gauge and the distance measuring cylinder will change again. At this time, the user can measure the distance of the pipe change according to the amount of the catheter during the two changes of the distance measuring cylinder, so that the user's subsequent maintenance is more convenient.

The invention relates to a mobile electrical cabinet. The cabinet comprises a track plate and a cabinet group. The cabinet group is mounted at the lower end of the track plate in a sliding fit manner.The invention relates to the mobile electrical cabinet. According to the invention, the electrical cabinet is used based on the design concept of mobile multi-stage wire arrangement; the electrical cabinet can be installed on the top of a wall, and the mounting position of the electrical cabinet on the top of the wall can be determined as required; the mobile electrical cabinet occupies a small area, which saves ground space; the whole placing space is tidy and clear; a wire arrangement board provided by the invention can arrange wires outside the electrical cabinet; the wires can be horizontally routed along the top of the mounting wall, which avoids disorder with other wires and a phenomenon of hanging falling, and facilitates subsequent maintenance; and concave arc grooves in the wirearrangement board can play a role in limiting and fixing the wires placed thereon, so as to prevent movement of the wires.

The invention discloses a radio marine communicator display control unit device with a protection mechanism. The radio marine communicator display control unit device comprises a bottom fixing plate,an upper fixing plate is arranged on the top face of the bottom fixing plate, a mounting groove is formed in the middle of the top face of the upper fixing plate, a connecting bottom plate is formed on the bottom face of a display control unit of a radio shipway, the mounting groove sleeves the connecting bottom plate in an inserted mode, and the connecting bottom plate abuts against the bottom face of the mounting groove. The radio marine communicator display control unit device can be fixed to an operation table, the display control unit of the demountable radio shipway can be mounted on theradio marine communicator display control unit device, the radio marine communicator display control unit device is convenient to demount and mount, and subsequent repair and maintenance are facilitated; meanwhile, a demountable cover plate mounted on the device can prevent manual-screwing bolts from being unscrewed, the situation that a hull operates for a long time and consequently, the manual-screwing bolts loosen and fall off is prevented, and firm fixing is ensured; and the radio marine communicator display control unit device adopts a demountable protection cover so that the display control unit of the radio shipway can be protected, and when the hull is unstable, people or other objects do not collide with the display control unit of the radio shipway directly.

The invention provides a novel detecting and isolating system for a fault of a RS-485 port, which comprises a bus and a plurality of slave nodes connected with the bus, wherein each of the slave nodes comprises an RS-485 communication circuit, an MCU (Micro Controller Unit) and a relay; the MCU is connected with a normally opened end of the relay and the RS-485 communication circuit; and the relay is connected with the RS-485 communication circuit and an RS-485 bus. The slave nodes of the novel detecting and isolating system for the fault of the RS-485 port can judge whether the RS-485 bus communication is abnormal or not. If the communication is abnormal, the slave nodes can automatically disconnect from the RS-485 system bus and can carry out data communication with the RS-485 communication circuit through IO ports of the slave nodes, so as to detect whether the RS-485 communication circuit can normally work or not.
