Description

Technical Field

[0001] This utility model belongs to the field of grounding impedance detection technology, specifically relating to a grounding impedance detection device based on harmonic analysis. Background Technology

[0002] Grounding impedance refers to the resistance performance of a device's grounding system. It is the voltage generated by current flowing through the grounding resistance in a circuit. The principle of grounding impedance testing is to measure the magnitude of the grounding resistance and calculate the value of the grounding current according to Ohm's law, thereby determining the resistance performance of the grounding system.

[0003] In current grounding impedance testing, it is necessary to select a ground location, insert a probe at a suitable position, and connect the grounding impedance testing equipment to the grounding electrode test point for testing. However, in field operations, the ground is usually uneven, and it is difficult to ensure the stable operation of the grounding impedance testing equipment. Therefore, it is necessary to design a grounding impedance testing device based on harmonic analysis. Utility Model Content

[0004] The purpose of this invention is to provide a grounding impedance detection device based on harmonic analysis, which aims to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A grounding impedance detection device based on harmonic analysis includes a main frame assembly, a grounding impedance detector is attached to the inner wall of the main frame assembly, a limiting assembly is fixedly connected to the outer wall of the main frame assembly, a grinding assembly is provided on the outer wall of the main frame assembly, a side support assembly is provided on the outer wall of the main frame assembly, and a wire take-up assembly is provided on the outer wall of the main frame assembly.

[0007] The main frame assembly includes a main frame, with extension plates fixedly connected to both sides of the main frame, and a small support plate slidably connected to the inner wall of the front end of the main frame;

[0008] The take-up assembly includes a take-up rack fixedly mounted on the outer wall of the main frame. A take-up motor is fixedly connected to the outer wall of the take-up rack, and the output shaft of the take-up motor is fixedly connected to a take-up rod via a coupling. With the take-up assembly, during use, the take-up motor drives the take-up rod to rotate, thereby realizing the orderly winding of the wires connected to the probe or grounding electrode test point, avoiding mutual crossing and interference between multiple wires, and improving the accuracy of the grounding impedance detector in field use.

[0009] The limiting component includes an outer support plate fixedly mounted on the outer wall of the main frame. A rotary motor is mounted above the outer support plate. The output shaft of the rotary motor is fixedly connected to a rotating rod via a coupling. A pressure plate is fixedly connected to the outer wall of the rotating rod. Multiple spring cylinders are arranged in an equidistant array at the bottom of the pressure plate, and rubber pads are fixedly connected to the bottom of each spring cylinder. Through the setting of the limiting component, during use, starting and controlling the rotary motor drives the pressure plate to rotate, positioning the multiple spring cylinders above the grounding impedance detector. Then, starting and controlling the side lifting hydraulic cylinder pulls the pressure plate downwards, causing the bottom of the spring cylinders to fit tightly against the top of the grounding impedance detector, thereby achieving a better limiting effect on the grounding impedance detector, improving the stability of the grounding impedance detector during field use, and facilitating the operation of the grounding impedance detector.

[0010] The grinding assembly includes a push hydraulic cylinder, one end of which is fixedly connected to a file. By setting up the grinding assembly and starting and controlling the use of the push hydraulic cylinder, the file can be pushed outwards reciprocally to grind and remove rust and debris from the outer wall of the probe and grounding electrode test point, thereby improving the accuracy of the data after insertion into the soil and improving the detection effect of the equipment.

[0011] The side support assembly includes a side frame, with a main lifting hydraulic cylinder fixedly connected to the inner wall of the side frame, and several pulleys fixedly connected to the bottom of the side frame. Through the side support assembly, the pulleys allow for convenient movement of the detection device during use, improving its applicability for outdoor applications. The main lifting hydraulic cylinder allows for adjustment of the height of both sides of the main frame assembly according to the specific outdoor location, ensuring the grounding impedance detector remains horizontal and stable for optimal performance.

[0012] In a preferred embodiment of this utility model, the number of the take-up components is four, and the four take-up components are symmetrically arranged at the front and rear ends of the main frame component.

[0013] In a preferred embodiment of this utility model, a pull block is fixedly connected to the outer wall of the small tray, and the small tray is positioned directly below the grinding assembly.

[0014] In a preferred embodiment of this utility model, a side lifting hydraulic cylinder is fixedly connected to the top of the outer support plate, and the top of the side lifting hydraulic cylinder is fixedly connected to the bottom of the rotary motor through a connecting seat.

[0015] In a preferred embodiment of this utility model, a connecting block is fixedly connected to the bottom of the pushing hydraulic cylinder, and two side support plates are fixedly connected to the outer wall of the main frame, with the two side support plates and the connecting block being movably connected by a pivot pin.

[0016] In a preferred embodiment of this utility model, there are multiple main lifting hydraulic cylinders, and the top of the main lifting hydraulic cylinders is fixedly connected to the bottom of the extension plate.

[0017] In a preferred embodiment of this utility model, there are two side support components, and the two side support components are symmetrically arranged on both sides of the main frame.

[0018] In a preferred embodiment of this utility model, there are two side frames, and the inner wall of the side frame slides in contact with the outer wall of the extension plate.

[0019] Compared with the prior art, the beneficial effects of this utility model are: by setting up the take-up assembly, during use, the take-up motor drives the take-up rod to rotate, thereby realizing the orderly winding of the wires connected to the probe or grounding electrode test point, avoiding the mutual crossing and interference between multiple wires, and improving the accuracy of the grounding impedance detector in the field.

[0020] By setting the limiting component, during use, the rotating motor is started and controlled to drive the pressure plate to rotate, so that multiple spring cylinders are above the grounding impedance detector. Then, the side lifting hydraulic cylinder is started and controlled to pull the pressure plate down, so that the bottom of the spring cylinders is tightly fitted with the top of the grounding impedance detector, thereby achieving a better limiting effect on the grounding impedance detector, improving the stability of the grounding impedance detector when used in the field, and facilitating the operation of the grounding impedance detector.

[0021] By setting up the grinding component and using the starting and controlling push hydraulic cylinder, the file plate can be pushed outwards reciprocally to grind and remove rust and debris from the outer wall of the probe and grounding electrode test point, thereby improving the accuracy of data after insertion into the soil and improving the detection effect of the equipment.

[0022] With the side support components and several pulleys, the testing device can be easily moved to different positions during use, thus improving its applicability for outdoor use. The main lifting hydraulic cylinder can be operated to adjust the height of the main frame components on both sides according to the specific location during outdoor use, thereby keeping the grounding impedance tester in a horizontal and stable state for better performance.
