Description

Technical Field

[0001] The present invention relates to a foundation settlement monitoring device, specifically a detection device applied to the foundation settlement of a substation. Background Technique

[0002] After the substation is built and put into operation, the foundation of the substation will have different degrees of settlement problems, posing a major threat to the safe operation of the substation. Especially for the GIS equipment of the substation, once the foundation settles, it will cause the foundation to sink, the pipeline to be misaligned, and the sulfur hexafluoride to leak, resulting in very serious consequences. To ensure the stable operation of the substation, it is necessary to closely monitor the foundation settlement of the substation and regularly carry out foundation settlement monitoring work.

[0003] The instruments and equipment used in the application of precise geometric leveling measurement technology to the foundation settlement monitoring of substations mainly include precise level instruments and leveling rods. To ensure the monitoring accuracy, invar leveling rods are selected. The invar leveling rod usually has an invar alloy tape installed in the center of a wooden frame. Since the invar alloy tape is a metal conductive tape, a grounding wire must be installed on the invar leveling rod when operating in the energized area of the substation; this makes it necessary to install the grounding wire during each measurement process, and the grounding wire must be disassembled and carried to the next measurement station every time an operation at one measurement station is completed and transferred to the next measurement station. This not only makes it inconvenient to install the grounding wire, but also the current grounding wire is long and messy, making it inconvenient to carry, and often requires special cooperation of multiple people, bringing many inconveniences to the settlement monitoring work.

[0004] The existing method is to set a slidable mounting seat on the invar leveling rod to rotate and wind up the grounding wire. This method is relatively convenient, but in most cases, the grounding wire is directly wound around the outside of the invar leveling rod, which is very inconvenient. Therefore, technical personnel in this field have proposed a detection device applied to the foundation settlement of a substation to solve the problems raised in the above background. Summary of the Invention

[0005] The purpose of the present invention is to provide a detection device applied to the foundation settlement of a substation to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

[0007] A detection device applied to the foundation settlement of a substation, including an invar leveling staff. A limiting chute is fixedly connected to the side of the invar leveling staff. Limiting sliders are symmetrically and slidably connected up and down inside the limiting chute. Horizontal fixing rods are fixedly connected to the right sides of the limiting sliders. A number of fixing rings are fixedly connected to the outside of the horizontal fixing rods. The grounding wire of the invar leveling staff alternately passes through the upper and lower fixing rings in sequence; Rotating rods are rotatably connected to the inner sides of the limiting sliders, and the outer ends of the rotating rods are rotatably connected to threaded connection blocks. A fixing bolt is threaded on the threaded connection block. A positioning connection block is fixedly connected to the middle of the limiting chute, and the fixing bolt is in threaded fit with the positioning connection block.

[0019] The present invention will be further described below in conjunction with the accompanying drawings of the specification and specific preferred embodiments, but the protection scope of the present invention is not limited thereby.

[0020] Please refer to Figures 1 - 3 , a detection device applied to the foundation settlement of a substation, including an invar leveling staff 1. A limiting sliding groove 2 is fixedly connected to the side of the invar leveling staff 1. Limiting sliding blocks 3 are symmetrically and slidably connected up and down inside the limiting sliding groove 2. Horizontal fixing rods 4 are fixedly connected to the right sides of the limiting sliding blocks 3. A plurality of fixing rings 5 are fixedly connected to the outside of the horizontal fixing rods 4. The grounding wire of the invar leveling staff 1 alternately passes through the upper and lower fixing rings 5 in sequence;

[0021] When in use, by unscrewing the fixing bolt 8, the threaded connection block 7 is disengaged from the positioning connection block 9, and the outer end of the inclined rod 6 can be pulled outwards. After being pulled out, the limiting sliding blocks 3 move towards each other. At this time, the fixing rings 5 on the horizontal fixing rods 4 will move downwards;

[0022] Inclined rods 6 are rotatably connected to the inner sides of the limiting sliding blocks 3. The outer ends of the inclined rods 6 are rotatably connected to the threaded connection blocks 7. A fixing bolt 8 is threadedly connected to the threaded connection block 7. A positioning connection block 9 is fixedly connected to the middle of the limiting sliding groove 2. The fixing bolt 8 is in threaded fit connection with the positioning connection block 9;

[0023] After the fixing rings 5 are close to each other, the grounding wire can be pulled out. The grounding wire is used for measurement. After the measurement is completed, the threaded connection block is pressed inwards, the fixing rings 5 move away from each other, and the grounding wire will be retracted, which is convenient for moving the device to perform multiple measurements.

[0024] There are 2 - 5 fixing rings 5, preferably 4.

[0025] A limiting retaining ring 10 is fixedly connected to the end of the grounding wire of the invar leveling staff 1.

[0028] The working principle of the present invention is: when in use, by unscrewing the fixing bolt 8, the threaded connection block 7 is disengaged from the positioning connection block 9, and the outer end of the inclined rod 6 can be pulled outwards. After being pulled out, the limiting sliding blocks 3 move towards each other. At this time, the fixing rings 5 on the horizontal fixing rods 4 will move downwards. At this time, the grounding wire can be pulled out. The grounding wire is used for measurement. After the measurement is completed, the threaded connection block is pressed inwards, the fixing rings 5 move away from each other, and the grounding wire will be retracted, which is convenient for moving the device to perform multiple measurements.
