Description

Technical Field

[0002] The power grid is a crucial infrastructure related to energy security and national security, and substations are vital power facilities within power grid projects. With my country's rapid economic development and social progress, the demand for power grid construction is constantly increasing. In particular, with the transformation of old mining areas and urbanization, more and more substations need to be built in coal mine goaf areas. Under the disturbance caused by the construction of substations in goaf areas and the loads imposed by the substations, the original equilibrium state of the foundation in the old goaf areas is disrupted. The interaction and coordinated settlement of the overlying soil and rock further amplify the residual settlement and deformation of the old goaf areas, leading to surface movement and deformation. Therefore, settlement and deformation are one of the most significant factors threatening the operational safety of substation buildings and equipment.

[0003] Currently, the static leveling sensors installed in the operating area of ​​substations in mining subsidence areas can detect settlement, but a single detection point cannot detect the settlement of large-scale building substations. Multiple static leveling sensors need to be installed within the substation area. Due to the distance between each static leveling sensor, there are large height errors between the sensors in the substation during installation. In addition, the lack of stable support during sensor installation leads to large installation errors, which affects the accuracy of settlement monitoring and makes installation and monitoring difficult.

The application layer includes a cloud platform data management center, a data server, and an application server.

[0030] The method of use in this embodiment is as follows: For settlement monitoring in a goaf substation, firstly, several static leveling sensors 5 are installed at the settlement monitoring point of the goaf substation using auxiliary installation equipment to form a detection system. This involves moving the auxiliary installation equipment to the installation position, placing the static leveling sensors 5 on the auxiliary installation equipment, adjusting the static leveling sensors 5 to the required installation height using the auxiliary installation equipment, and then fixing the static leveling sensors 5 on the installation surface of the settlement monitoring point in the goaf substation. Next, the auxiliary installation equipment uses a laser to locate the next installation point for the static leveling sensor 5 and marks the installation point. Then, the auxiliary installation equipment is separated from the fixedly installed static leveling sensors 5, and the static leveling sensor is installed at the marked installation point using the auxiliary installation equipment. Sensor 5, repeating the operation, finally uniformly numbered the several static leveling observation sensors 5 installed at the settlement monitoring points of the goaf substation. The static leveling observation sensors 5 installed at the settlement monitoring points of the goaf substation are used to monitor the settlement of the goaf substation. The detection system uses the static leveling observation method to automatically and in real time observe and monitor the settlement of the building structures and equipment foundations of the goaf substation. The detection system composed of several static leveling observation sensors 5 feeds back the monitoring data to the data demodulation instrument through the communication bus. The data demodulation instrument transmits the data to the field data acquisition and analysis computer through the local area network. The field data acquisition and analysis computer transmits the data to the cloud platform data management center through the wireless communication network. The cloud platform data management center transmits the data back to the application server through the data server.

[0031] When using the settlement monitoring device for the substation in the goaf area, the rollers 8 on the base 7 are rolled by pushing the handle 9 to move the equipment to the installation point. The static leveling sensor 5 is placed inside the mounting sleeve 42, and the mounting base 41 supports the static leveling sensor 5. The mounting block 61 on the static leveling sensor 5 protrudes from the mounting notch 43 outside the mounting sleeve 42. Then, according to the installation height of the static leveling sensor 5, the mounting plate 62 is fixed to the installation surface of the settlement monitoring point of the substation in the goaf area with bolts. The hydraulic lift 2 is used to lift the installation platform 1, the mounting frame 4, and the static leveling sensor. The height of the leveling sensor 5 is adjusted so that the height of the mounting block 61 on the static leveling sensor 5 is consistent with the height of the monitoring point. A fine adjustment is made to push the device, and the spring 15 on the guide rod 12 provides elastic support to the support base 13, allowing the mounting block 61 on the static leveling sensor 5 to be inserted into the mounting bracket 63. Then, the mounting block 61 and the mounting bracket 63 are fixedly installed using assembly bolts 64. The servo motor 38 drives the worm gear 37 to rotate, which in turn drives the meshing worm wheel 36 to rotate. The rotation of the worm wheel 36 drives the gear 35 to rotate via the connecting shaft, and the rotation of the gear 35 drives the meshing external gear disc. 31 rotates on the outside of the support platform 14, causing the point-finding turntable 33, on which the point-finding laser probe 34 is installed, to rotate circumferentially on the support platform 14 below the mounting base 41. The laser line emitted by the point-finding laser probe 34 is used to locate the installation point height of the next static leveling observation sensor 5 and to mark the point location. Then, the hydraulic lift 2 moves down, and the installation platform 1 and mounting frame 4 move down, separating the auxiliary installation equipment from the static leveling observation sensor 5 fixedly installed at the monitoring point. The auxiliary installation equipment is then moved to the marked position, and the point-finding laser probe 34 is rotated and adjusted so that the laser line is directed towards the marked position. The location of the point mark is determined, and the installation platform 1 and mounting frame 4 are raised by the hydraulic lift 2 so that the laser line emitted by the point-finding laser probe 34 coincides with the location of the fixed point mark. Then, the height of the auxiliary installation equipment is adjusted to the installation height required for the static leveling observation sensor 5 installation support. The installation and point-finding positioning operation of the static leveling observation sensor 5 is repeated. The auxiliary installation equipment facilitates the installation of the static leveling observation sensor 5 at the monitoring point of the substation in the goaf area. The support height can be adjusted according to the installation height of the static leveling observation sensor 5 monitoring point. The stable support makes the installation and operation of the static leveling observation sensor 5 convenient and accurate.The point-finding mechanism 3 on the auxiliary installation equipment utilizes the laser line emitted by the point-finding laser probe 34 to facilitate the positioning of multiple static leveling observation sensors 5 at various monitoring points. This allows the static leveling observation sensors 5 at several monitoring points to be accurately installed at the same horizontal level, reducing the height difference between monitoring points and thus minimizing monitoring errors. This improves the accuracy of settlement monitoring in the goaf substation. Furthermore, the point-finding turntable 33, in conjunction with the external gear plate 31, gear 35, worm gear 36, and worm 37, allows the point-finding laser probe 34 to rotate and perform point finding in any direction along a 360-degree circle at the same horizontal level. This provides a wide point-finding range, and the point-finding laser probe 34 self-locks and remains stable after finding a point.
