Embodiment 1

[0029] Embodiment 1, this embodiment provides a power cable bridge inspection system, including a bridge mechanism, a cover opening mechanism arranged on the bridge mechanism, a track mechanism arranged in the bridge mechanism, and an inspection mechanism arranged on the track mechanism And a retractable mechanism for setting out the inspection mechanism; the inspection mechanism includes a mobile base arranged on a track mechanism, and a control mechanism 3, a power supply mechanism and a monitoring mechanism 32 are set on the mobile base, and the control mechanism 3 and monitoring center 31 communication connection. The opening mechanism is convenient to open an operation hole to operate the inspection system. After the inspection is completed, the opening mechanism can be closed again to prevent small animals and dust from entering. The track mechanism is convenient for the inspection mechanism to guide and move in the bridge mechanism, and the retractable mechanism is to r...

Embodiment 2

[0034] The difference between this embodiment and Embodiment 1 is:

[0035] The control mechanism 3 includes a microcontroller, the power supply mechanism includes a lithium battery 4 that supplies power to the control mechanism 3 and a power supply line 13 that supplies power to the drive motor 10, and the monitoring mechanism 32 includes a temperature and humidity sensor 5, a smoke sensor 6, Infrared camera 7 ; the control mechanism 3 is connected with the monitoring mechanism 32 and the drive motor 10 , and the power supply mechanism is connected with the control mechanism 3 and the drive motor 10 . The microcontroller is a single-chip microcomputer that integrates the main part of the microcomputer on a chip, which can meet the control requirements of the scene. The lithium battery supplies power to the control mechanism and the monitoring mechanism, and its power consumption is very small, and the battery can provide enough electric energy. The driving motor consumes a l...

Embodiment 3

[0037] The difference between this embodiment and Embodiment 1 is:

[0038] The monitoring center 31 includes a PLC controller 30 connected to the control mechanism 3 by wires, and the PLC controller 30 is connected with an operation button 28 and a display 29 . The monitoring center is on site for the staff to control the inspection agency, and at the same time display the information detected by the inspection agency. Its preferred PLC controller is a digital electronic device with a microprocessor, a digital logic controller for automatic control, and can load control instructions into the memory for storage and execution at any time. Of course, you can also directly modify the notebook as the control center.

[0039] The retracting mechanism includes a bobbin 26 and a bobbin 27 disposed on the bobbin 26 , and the power supply line 13 is wound on the bobbin 27 . The retracting mechanism is to wind and retract the power supply lines and communication lines to avoid too muc...

Abstract

The invention provides a power cable bridge inspection system. The power cable bridge inspection system comprises a bridge mechanism, an uncovering mechanism arranged on the bridge mechanism, a trackmechanism arranged in the bridge mechanism, an inspection mechanism arranged on the track mechanism and a winding and unwinding mechanism used for unwinding the inspection mechanism. The inspection mechanism comprises a movable base arranged on the track mechanism, a control mechanism, a power supply mechanism and a monitoring mechanism are arranged on the movable base, and the control mechanism is in communication connection with the monitoring center. According to the invention, cables of the bridge mechanism can be inspected, internal temperature, humidity and smoke can be monitored, internal images can be fed back for workers to view, fault points can be found when faults occur, inspection of the cables in the bridge mechanism can be easily completed, and long-term smooth operation ofthe cables can be ensured.

Description

technical field [0001] The invention relates to the technical field of power cable monitoring, in particular to a power cable bridge inspection system. Background technique [0002] With the continuous expansion of China's electric power industry, data communication industry, urban rail transit industry, automobile industry, and shipbuilding industries, the demand for wires and cables will also increase rapidly. The existing cable tray includes a U-shaped body and a cover plate. The cable is laid in the U-shaped inner body during use. However, the cable tray is closed for a long time. If the cable inside the cable encounters heat or is damaged When damaged, it cannot be found in time, and it is extremely inconvenient to overhaul after the cable is damaged. Although the existing technology for monitoring the inside of the cable tray exists, because of its narrow space and overhead installation, many places cannot be monitored at all, and there are great hidden dangers.
