Problems solved by technology

[0002] At present, the "information island" existing in the construction of smart cities in my country has led to relatively isolated and closed city data, and the informatization monitoring of urban multi-energy underground pipe network is not comprehensive, especially the underground power pipe network information system is relatively backward. Traditional pipe network information Disadvantages of the system: slow search and query speed, heavy workload, difficulty in updating information, and difficulty in maintaining timeliness of information; in order to change the problems of low work efficiency, accuracy and timeliness of information in the power pipe network information system, it is necessary to ensure The integrity, completeness, accuracy and timeliness of the basic data of the underground power pipeline network, so the pipeline detector came into being
[0010] The first three methods above, the measurement accuracy is not high, the deeper the buried depth, the worse the accuracy, the operation is inconvenient, and the efficiency is low
In the fourth method, the electronic compass will be disturbed by the geomagnetism and the surrounding environment magnetic field, the azimuth data is not accurate enough, the precision is low, and the scope of application is limited.
The disadvantages are: (1) due to the integration of navigation information, the positioning error increases with time, and the long-term accuracy is poor; (2) it takes a long time for initial alignment before each use; (3) the price of the equipment is relatively high expensive

Abstract

The invention discloses an information detector for an underground power pipe network, which is used for measuring the driving distance by virtue of odometers arranged on walking wheels, and is high in precision and small in accumulated error. The optical fiber gyroscope is used as a sensor for acquiring a pitch angle and a yaw angle, so that the precision is high; the detector is provided with acommunication unit, a memory, a data interface unit and an external memory interface, so that various data transmission modes can be selected; the detector is also provided with a rechargeable power supply and a switch, is convenient to use, and is energy-saving and environment-friendly; the detector detection vehicle is provided with the traction device and the walking supporting device, expansion of the walking wheels can be kept, the distance between the walking wheels and the traction rod is adjusted, equipment can be placed into pipelines with different outer diameters, and the walking wheels can be kept to be tightly attached to the inner walls of the pipelines through the tension springs; the detector body adopts a cabin type hollow cylinder sealing structure and has the functions of dust prevention, water prevention, corrosion prevention, electromagnetic interference prevention and pipeline damage prevention.
