Description
Technical Field
[0001] The utility model belongs to the technical field of patrol inspection devices, and particularly relates to a rail-hanging fixed-point patrol inspection device applied to a comprehensive pipe gallery. Background Art
[0002] Urban underground utility corridors are one of the necessary infrastructures for the development of livable smart cities and are also a key project in current urban construction. The construction of urban utility corridors has become a development trend worldwide. Urban underground utility corridors are intensive public tunnels that contain a variety of pipelines and equipment such as water conservancy systems, gas systems, power systems, thermal systems, communication systems, and fire protection systems. It can effectively save urban ground space and improve resource utilization efficiency, and is the key to the normal and efficient operation of urban management. However, there are still many challenges in the long-term stable operation of utility corridors.
[0003] First, during the long-term use of pipelines, due to erosion by environmental conditions, natural aging of materials, or various external interference factors, the pipelines inside the corridor may be damaged, causing safety problems such as water leakage and circuit short circuits, or other potential risks. Secondly, most of the integrated corridors are buried deep underground, with limited space and complex environment, which increases the difficulty of implementing traditional inspection and maintenance work. Especially in the face of emergencies, due to these unfavorable conditions, it becomes particularly difficult to take countermeasures quickly and effectively. These problems will not only cause economic losses, but may also pose a serious threat to the safe and stable operation of urban infrastructure.
[0004] At present, the inspection work inside the pipeline is mainly carried out manually. However, due to the narrow space of the pipeline and the complex and changeable inspection environment, manual inspection not only faces the challenges of difficult operation and heavy workload, but also has low efficiency. In addition, manual inspection may also cause some abnormal conditions to be missed due to differences in personal subjective judgment, resulting in failures. Once there are defects or potential risks in the pipeline, it may trigger safety incidents such as toxic gas leakage and equipment failure, which seriously threaten the safety of the staff. Another alternative is to use manually controlled camera devices for inspection. Although this method can cover some areas that are difficult to reach manually, it still requires personnel to control the equipment to move inside the pipeline in real time, so it is impossible to realize the automation of the inspection process. Inspections perform daily tasks in underground integrated pipe corridors, and the information that needs to be transmitted is large and real-time. Existing signal transmission methods such as ZigBee and Bluetooth wireless communication methods have short transmission distances and low transmission rates, which are not suitable for pipe corridors; because the pipe corridor is underground, it is difficult to cover the base station signal outside. If a base station is set up inside the pipe corridor, it is necessary to cover the entire corridor, and the construction and operation costs are very high. Utility Model Content
[0005] In view of the above-mentioned problems, the purpose of the utility model is to provide a rail-mounted fixed-point inspection device applied to an integrated pipeline corridor, which not only realizes automated inspection, but also has a signal relay function, ensuring the stability of data transmission and the accuracy of positioning.
