Description

Technical Field

[0001] The utility model belongs to the technical field of pipe network detection, and in particular relates to a tool for detecting pipe networks in urban underground spaces. Background Art

[0002] In the current field of urban underground pipe network detection, detection tools face some technical challenges. First, due to the variety of sizes of underground pipes, from small drainage pipes to large main pipes, detection tools often have difficulty adapting to such size diversity, resulting in poor detection results. Second, the detection tools are not stable enough during actual use and are easily disturbed by the surrounding environment, such as soil conditions, groundwater levels, adjacent pipelines, etc. These factors will affect the accuracy and reliability of detection.

[0003] These limitations have had an adverse impact on the maintenance and management of urban underground pipe networks, limiting the efficiency and safety of detection work. Therefore, in order to improve the performance of detection tools, meet the detection needs of pipelines of different sizes, and enhance their stability in complex environments, the development of new, highly stable detection technologies has become an important research direction in this field. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide an urban underground space pipe network detection tool to solve the problems raised in the above background technology. Due to the diverse sizes of underground pipes, from small drainage pipes to thick main pipes, the detection tools are often difficult to adapt to such diversity of sizes, resulting in poor detection effect. Secondly, the detection tool is not stable enough during actual use and is easily disturbed by the surrounding environment, such as soil conditions, groundwater level, adjacent pipelines, etc. These factors will affect the accuracy and reliability of detection.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an urban underground space pipeline detection tool, comprising a device body, both side surfaces of the device body are fixedly connected with detection cameras, the side surfaces of the device body are fixedly connected with a base, four of the bases are provided, the surfaces of the four bases are fixedly connected with a telescopic rod structure, the surface of the telescopic rod structure is provided with a spring structure, the output end of the telescopic rod structure is transmission-connected with a connecting structure, one end of the connecting structure is fixedly connected with a driving motor, and the output end of the driving motor is transmission-connected with a rubber wheel.

[0006] Preferably, a searchlight is fixedly connected to the side surface of the device body.

[0007] Preferably, an outer side of the detection camera is fixedly connected to an outer frame, and a sliding groove is provided on an inner side of the outer frame.

[0008] Preferably, the upper end of the sliding groove is fixedly connected to a driving motor, the output end of the driving motor is transmission-connected to a threaded screw, and the surface of the threaded screw is threadedly connected to a sliding rod.

[0009] Preferably, a plurality of cylindrical brushes are fixedly connected to the inner surface of the sliding rod.

[0010] Preferably, a sensor group is arranged inside the device body.

[0011] Preferably, the sensor group includes an underground pipeline inertial positioning device, a geophysical detection sensor, a distributed optical fiber sensor and a ground penetrating radar sensor.

[0012] Compared with the prior art, the utility model provides a tool for detecting urban underground space pipe networks, which has the following beneficial effects:

[0013] 1. The utility model is provided with a telescopic rod structure and a spring structure. When in use, the detection tool is placed inside the underground space pipe network. The rubber wheel and the inner wall of the pipe network are in contact with each other. The rubber wheel is squeezed to the inner wall of the pipe network by the outward elastic force of the telescopic rod structure and the spring structure, so that the detection tool is more stable in the process of moving on the inner wall of the pipe network, and the image detected by the detection camera is more stable and clear. The rubber material of the rubber wheel also increases the friction between the detection tool and the pipe network, thereby further ensuring the stability of the operation of the detection tool, effectively avoiding the problem that due to the diverse sizes of underground pipes, from small drainage pipes to large main pipes, the detection tool is often difficult to adapt to such size diversity, resulting in poor detection effect. Secondly, the detection tool is not stable enough in actual use and is easily disturbed by the surrounding environment, such as soil conditions, groundwater level, adjacent pipelines, etc. These factors will affect the accuracy and reliability of detection.

[0014] 2. The utility model is provided with a driving motor. When the inner wall of the pipe network is detected by the detection tool, the driving motor drives the threaded screw to rotate, so that the sliding rod slides up and down on the surface of the detection camera. At the same time, the cylindrical brush on the inner surface of the sliding rod cleans the dust and stains on the surface of the detection camera, thereby ensuring the clarity of the picture taken by the detection camera;

[0015] 3. The utility model ensures that the detection tool can clearly detect the specific conditions of the inner wall of the pipeline network in a dark environment by setting up a searchlight. By setting up a sensor group, the autonomous navigation technology of the spacecraft is used through the inertial positioning instrument of the underground pipeline. Through the combined navigation and multi-sensor information fusion technology, the three-dimensional information of the underground pipeline in the complex urban environment is obtained. Through geophysical detection sensors, including microgravity, high-density electrical method, shallow reflection seismic, surface wave exploration, ground penetrating radar, etc., the existence and position of the underground pipeline are determined by measuring the characteristics of the physical field distribution. Through distributed optical fiber sensors, it is used to perform real-time monitoring of underground pipelines, including pipeline leakage monitoring, third-party intrusion monitoring, deformation monitoring, corrosion monitoring, geological and natural disaster monitoring and submarine pipeline monitoring, etc. Through ground penetrating radar sensors, a non-destructive detection method is used to efficiently detect underground public facilities, such as pipelines, without damaging the ground.
