Description

Technical Field

[0001] This invention relates to the field of current detection technology and is a monitoring device for ultra-high voltage grounding electrodes. Background Technology

[0002] A grounding electrode is a conductor or combination of conductors buried in the earth to connect with it. As a metallic conductor or group of conductors in direct contact with the soil, it is mainly divided into artificial grounding electrodes and natural grounding electrodes. The core function of a grounding electrode is to provide an electrical connection with the earth through close contact with the soil, thereby safely dissipating lightning energy and discharging it into the earth. In practical applications, grounding electrodes need to be connected to grounding wires, and usually two or more grounding electrodes are buried in the earth, forming a current loop with the earth. Since the maximum current in this loop can reach tens of amperes, which may cause the grounding electrode to burn out, a grounding electrode current monitoring device must be used to detect the current during the installation and subsequent maintenance of the grounding electrode to ensure that it meets safety standards.

[0003] Currently, there are various types of grounding electrode current monitoring devices on the market, among which the most common is the clamp meter. The clamp meter consists of a current clamp and an ammeter. When in use, the current clamp is opened, and the grounding wire connected to the grounding electrode is clamped around it, and the monitoring data can be read through the ammeter.

[0004] However, in ultra-high voltage (UHV) scenarios, when the voltage is too high, workers face the risk of electric shock even without direct contact with the power lines, thus requiring a sufficiently safe distance. Existing monitoring equipment (such as conventional clamp meters) lacks extension capabilities, forcing workers to get as close to the power lines as possible to operate the equipment and take measurements, which undoubtedly increases the risk of electric shock significantly.

[0005] Therefore, inventing an ultra-high voltage grounding electrode monitoring device that can be operated remotely to solve the safety hazards caused by the inability to extend the lifespan of existing equipment is of great practical significance. Summary of the Invention

[0006] This invention provides an ultra-high voltage grounding electrode monitoring device that overcomes the shortcomings of the prior art and can effectively solve the safety hazards caused by the inability to extend the lifespan of existing equipment.

[0007] The technical solution of the present invention is achieved through the following measures: an ultra-high voltage grounding electrode monitoring device includes an ammeter body, an installation cavity is provided inside the ammeter body, a first sliding groove is provided inside the installation cavity, a moving rod is connected inside the first sliding groove, a gear is connected to the inner wall of the installation cavity by a rotating shaft, a rack is connected to one side of the moving rod, the rack and the gear mesh with each other, a motor is connected to the outer wall of the ammeter body, the output end of the motor passes through the ammeter body and is connected to the rotating shaft of the gear, an opening corresponding to the moving rod is provided on the ammeter body, an extension rod is connected to the top of the moving rod, a fixed frame is connected to the top of the extension rod, a movable clamp is connected to the fixed frame by a rotating shaft, and a movable component is provided on one side of the outer wall of the extension rod.

[0008] The following are further optimizations and / or improvements to the above-mentioned technical solution: The aforementioned movable components may include a first upright plate connected to the outer wall of the extension rod, a first mounting port on the first upright plate, a sleeve connected to the first mounting port, a second sliding groove on the inner wall of the sleeve, a sliding block connected in the second sliding groove, a first rotating frame connected to one side of the sliding block, two first connecting rods connected to the first rotating frame by a rotating shaft, a second connecting rod connected to one end of the first connecting rod by a rotating shaft, two second rotating frames connected to the outer wall of the movable clamp by a rotating shaft, the second connecting rods connected to the second rotating frames by a rotating shaft, a pull rod connected to one end of the sliding block, a through-hole corresponding to the sliding block on one end of the sleeve, a second upright plate connected to one side of the ammeter body, a circular opening corresponding to the pull rod on one end of the second upright plate and the sleeve, the sleeve passing through the circular opening and connected to a limit block.

[0009] An insulating layer may be provided around the body of the aforementioned ammeter.

[0010] An LCD screen and a switch may be installed on one side of the ammeter body.

[0011] A protective shell is fixedly connected to one side of the ammeter body.

[0012] The aforementioned motor can be a servo motor, and the output shaft of the servo motor is connected to the shaft of the gear via a coupling.

[0013] An operating handle may be provided at the end of the aforementioned pull rod away from the sliding block, and the surface of the operating handle may be provided with anti-slip texture.

[0014] The ammeter body may contain a controller, which is electrically connected to the motor and the LCD screen.

[0015] The ammeter body may also include a wireless communication module for transmitting monitoring data to a remote terminal.

[0016] This invention achieves long-distance safe monitoring of UHV grounding electrode current by setting up an extendable detection structure and linkage operation components. Its core lies in using a motor-driven rack and pinion transmission to move a movable rod and extension rod, pushing the movable clamp to a safe distance, preventing personnel from close contact with high-voltage power lines and significantly reducing the risk of electric shock. Simultaneously, through the coordinated action of the pull rod, sliding block, connecting rod, and rotating frame in the movable components, the opening and closing of the movable clamp can be remotely controlled, ensuring stable clamping of the power line and current detection. The outer insulation layer of the device further enhances operational safety, and the protective shell effectively protects the motor and other critical components from external environmental influences. The LCD screen and controller work together to intuitively present monitoring data and achieve precise control of the motor. Adding a wireless communication module can transmit data to a remote terminal, improving the convenience and real-time nature of monitoring. The overall structure, through the combination of mechanical transmission and electrical control, not only solves the safety hazards caused by the inability to extend the reach of traditional monitoring equipment but also ensures the stability and accuracy of the detection process. It is suitable for current monitoring scenarios in the installation and maintenance of UHV grounding electrodes, possessing high practical value and safety assurance capabilities.

Detailed Implementation

[0022] The present invention is not limited to the following embodiments, and the specific implementation can be determined according to the technical solution of the present invention and the actual situation.

[0023] The present invention will be further described below with reference to embodiments: Example 1: As shown in the attached document Figure 1 , 2As shown in Figures 3 and 4, the UHV grounding electrode monitoring device includes an ammeter body 1. An installation cavity is formed inside the ammeter body 1, and a first sliding groove is provided within the installation cavity. A moving rod 2 is connected to the first sliding groove. A gear 3 is connected to the inner wall of the installation cavity via a rotating shaft. A rack 4 is connected to one side of the moving rod 2, and the rack 4 meshes with the gear 3. A motor 5 is connected to the outer wall of the ammeter body 1. The output end of the motor 5 passes through the ammeter body 1 and is connected to the rotating shaft of the gear 3. An opening corresponding to the moving rod 2 is formed on the ammeter body 1. An extension rod 6 is connected to the top of the moving rod 2, allowing the movable clamp 8 to be extended to a safe position. A fixing frame 7 is connected to the top of the extension rod 6, and the movable clamp 8 is connected to the fixing frame 7 via a rotating shaft. A movable component 9 is provided on one side of the outer wall of the extension rod 6. In this embodiment, there are two movable clamps 8.

[0024] In this embodiment, the movable component 9 includes a first upright plate 10 connected to the outer wall of the extension rod 6. The first upright plate 10 has a first mounting port, and a sleeve 11 is connected to the mounting port. The inner wall of the sleeve 11 has a second sliding groove, and a sliding block 12 is connected to the sliding groove. A first rotating frame 13 is connected to one side of the sliding block 12. Two first connecting rods 14 are connected to the first rotating frame 13 by a rotating shaft. One end of the first connecting rod 14 is connected to a second connecting rod 15 by a rotating shaft. The outer wall of each movable clamp 8 is connected to two second rotating frames 16 by a rotating shaft. The second connecting rod 15 is connected to the second rotating frame 16 by a rotating shaft. One end of the sliding block 12 is connected to a pull rod 17. One end of the sleeve 11 has a through-hole corresponding to the sliding block 12. One side of the ammeter body 1 is connected to a second upright plate 18. One end of the second upright plate 18 and the sleeve 11 has a circular opening corresponding to the pull rod 17. The sleeve 11 passes through the circular opening and is connected to a limit block 19. The rotation of the movable clamp 8 is controlled by the limit block.

[0025] In this embodiment, an insulating layer 20 is provided around the ammeter body 1. The insulating layer 20 is made of rubber, which can enhance the protection of people.

[0026] In this embodiment, an LCD display screen 21 and a switch 22 are provided on one side of the ammeter body 1, which facilitates the control of the device.

[0027] In this embodiment, a protective shell 23 is connected to one side of the ammeter body 1, which can protect the motor 5.

[0028] The working principle of this invention is as follows: When measurement is required, press switch 22, the motor 5 works, drives the gear 3 to rotate, drives the rack 4 that meshes with it, causing the moving rod 2 to move. The moving rod 2 extends the fixed frame 7 and the movable clamp 8 to a sufficiently safe position through the extension rod 6. Press switch 22 again, the motor 5 stops working, pulls the limit block 19, drives the sliding block 12 and the first rotating frame 13 through the pull rod 17, and the first connecting rod 14 drives the second connecting rod 15, causing the movable clamp 8 to rotate. Place the wire to be monitored in the middle of the movable clamp 8, and the current can be detected.

[0029] This invention utilizes a combination of a moving rod, rack, gear, motor, extension rod, movable component, sleeve, sliding block, first rotating frame, first connecting rod, second connecting rod, second rotating frame, pull rod, and limit block. When measurement is required, the motor operates, driving the gear to rotate, which in turn drives the rack meshing with it, causing the moving rod to move. The moving rod, via the extension rod, extends the fixed frame and movable clamp to a sufficiently safe position, then pulls the limit block. The pull rod then drives the sliding block and the first rotating frame, and the first connecting rod drives the second connecting rod, causing the movable clamp to rotate. The wire to be monitored is placed in the middle of the movable clamp, allowing for current detection. This invention automatically extends the detection equipment to a sufficiently safe length for wire monitoring, significantly reducing the risk of electric shock to workers who are too close to the wire.

[0030] Example 2: As shown in the attached document Figure 1 , 2 As shown in Figures 3 and 4, in this embodiment of the UHV grounding electrode monitoring device, motor 5 is a servo motor, and the output shaft of the servo motor is connected to the rotating shaft of gear 3 via a coupling. The servo motor can receive control signals to precisely adjust the output speed and angle, and transmit power stably to gear 3 through the coupling, ensuring the transmission accuracy between gear 3 and rack 4. This allows for precise control of the extension distance of the moving rod 2 and the extension rod 6, enabling the movable clamp 8 to accurately reach the preset monitoring position, avoiding the impact of travel deviation on the monitoring effect, and improving the control accuracy and operational accuracy of the device.

[0031] In this embodiment, an operating handle is provided at the end of the pull rod 17 away from the sliding block 12, and the surface of the operating handle is provided with anti-slip texture. When the operator pulls the pull rod 17 by gripping the operating handle, the anti-slip texture increases the friction between the hand and the handle. This allows the operator to operate the pull rod 17 with less effort, prevents hand slippage during pulling, and improves the stability and convenience of operation, especially ensuring the reliability of operation in humid or oily environments.

[0032] Example 3: As shown in the attached document Figure 1 , 2As shown in Figures 3 and 4, in this embodiment of the UHV grounding electrode monitoring device, a controller is installed inside the ammeter body 1. The controller is electrically connected to the motor 5 and the LCD display 21. The controller receives external commands or preset programs to control the start, stop, and speed of the motor 5. Simultaneously, it receives the current signal transmitted by the movable clamp 8 and transmits the processed signal to the LCD display 21 for display. This enables automated control of the device, reduces manual intervention, makes the motor 5 run more accurately, and ensures more timely processing and display of current data, thereby improving the device's intelligence level.

[0033] In this embodiment, the ammeter body 1 is also equipped with a wireless communication module for transmitting monitoring data to a remote terminal. The wireless communication module receives the monitoring data processed by the controller and transmits the data to the remote terminal (such as a computer or mobile phone) via wireless signal. This enables remote sharing and viewing of monitoring data, allowing staff to obtain real-time data without being near the equipment, facilitating timely monitoring of the grounding electrode's current status. It is particularly suitable for centralized management of multiple monitoring points, improving the flexibility and efficiency of monitoring work.

[0034] The above technical features constitute the embodiments of the present invention, which have strong adaptability and implementation effect. Unnecessary technical features can be added or removed according to actual needs to meet the needs of different situations.
