Description

Technical Field

[0001] The utility model relates to the technical field of grounding devices, in particular to an electric digital display spiral grounding device for 10KV-110KV power transmission and distribution lines. Background Art

[0002] Since 90% of the transmission and distribution lines under the jurisdiction of Qinghai Province are located in mountainous terrain, and some towers are located in poor mountainous geological conditions with hard rock, sand, stone, hard soil and other hard materials, it is difficult to drive grounding wires and grounding piles when encountering such geological conditions during the power outage inspection and maintenance of the transmission and distribution lines. This can easily lead to safety hazards such as insufficient burial depth of the grounding wires and grounding piles due to the influence of natural geological conditions. According to the State Grid Electric Power Safety Work Regulations and relevant electrical construction specifications, the burial depth of the temporary grounding body and the top surface of the grounding pole should not be less than 0.6m. Insufficiently buried grounding bodies may cause the grounding resistance to fail to meet the standard, weakening the protective effect of the ground wire in the event of leakage. Therefore, there are two problems:

[0003] 1. Due to the special geological conditions, there are hard areas such as rock, sand, stone, and hard soil, making it difficult to insert artificial tools into the earth;

[0004] 2. It is impossible to determine whether the buried depth of the grounding body has reached the predetermined depth;

[0005] Therefore, an electric digital display spiral grounding device for 10kV-110kV transmission and distribution lines is developed to solve the problem of line grounding difficulties in areas with poor geological conditions, prevent the hidden dangers of insufficient grounding pile burial depth, ensure that the predetermined burial depth is reached, and ensure that safety measures are in place.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] This utility model designs an electric digital display spiral grounding device for 10KV~110KV power transmission and distribution lines. Through its unique design, it effectively solves two major problems encountered in grounding construction under specific geological conditions:

[0019] 1. Insertion problems in hard geological conditions:

[0020] Problem Description: In hard geological conditions such as rock, sandstone, and hard soil, traditional manual or mechanical methods often make it difficult to effectively and quickly insert grounding electrodes into the soil. This not only increases construction difficulty and labor costs, but may also affect the grounding effect.

[0022] Rotating and detachable chuck design: The rotating and detachable chuck not only facilitates connection with the grounding pin body, but also efficiently transmits the motor's power to the grounding pin through its rotational motion, ensuring stable and continuous power output during the screw-in process. At the same time, the detachable design facilitates removal or replacement for maintenance, increasing the flexibility and service life of the device.

[0023] 2. The problem of the grounding depth cannot be accurately determined:

[0024] Problem Description: During grounding construction, accurately controlling the burial depth of the grounding body is crucial. Insufficient burial depth will increase grounding resistance and affect grounding effectiveness; excessive burial depth may increase construction costs and time. However, traditional methods often make it difficult to accurately measure the actual burial depth of the grounding body.

[0025] Solution: Laser ranging module: This device has a laser ranging module fixed on the power head.

[0040] like Figures 1 to 5 As shown, it shows a specific embodiment of the utility model; Figures 1 to 5 As shown, the utility model discloses an electric digital display spiral grounding device for 10KV to 110KV power transmission and distribution lines, including a power head 1, a grounding pin body 2 and a laser ranging module 3. The power head 1 includes a start switch 1-1, a power battery, a motor 1-3, a rotating and detachable chuck 1-4 and a gripping portion 1-5. The output shaft of the motor 1-3 is connected to one end of the rotating and detachable chuck 1-4, and the other end of the rotating and detachable chuck 1-4 is connected to the grounding pin body 2;

[0041] The grounding pin body 2 includes a square connector, a grounding pin 2-1, a grounding wire lug 2-2, and a grounding wire mounting hole 2-3. One end of the square connector is connected to the rotatable detachable clamp 1-4, and the other end of the square connector is connected to the grounding pin 2-1. The grounding wire lug 2-2 is provided on the upper part of the grounding pin 2-1, and the grounding wire lug 2-2 is provided with a grounding wire mounting hole 2-3.

[0042] The laser distance measuring module 3 is fixedly arranged on the power head 1 .

[0043] Preferably, Figures 1 to 3 As shown, the laser ranging module 3 includes a shell, a laser ranging probe 3-1, a distance display screen 3-2, a ranging module switch 3-3, a control module and a charging port. The laser ranging probe 3-1 extends to the outside of the bottom of the shell, the distance display screen 3-2 and the ranging module switch 3-3 are arranged on the outer surface of the shell, the control module is arranged on the inside of the shell, and the charging port is arranged on one side of the shell.

[0044] In the laser ranging module 3, various components work together to achieve accurate depth measurement and intuitive data display functions. Its housing, as the main structural part of the laser ranging module 3, plays a role in protecting the internal electronic components and integrated circuits. It is usually made of strong and durable materials such as aluminum alloy or high-strength plastic to ensure that it can work normally without damage in harsh outdoor environments.

[0045] The laser ranging probe 3-1 is a core component of the laser ranging module. It is responsible for emitting the laser beam and receiving the reflected signal. This probe is designed with exceptional precision to ensure the laser beam is emitted at a stable angle and intensity, accurately measuring the distance from the emission point to the reflection point. In this device, the laser ranging probe 3-1 is cleverly extended to the outside of the bottom of the housing, allowing it to be directly aligned with the ground or the ground pin body for measurement, improving both accuracy and convenience.

[0046] The distance display screen 3-2 can display the measured distance data in real time. The distance display screen 3-2 is set on the outer surface of the shell, and its position is eye-catching and easy to observe. Construction personnel can adjust the screw-in depth of the grounding pin body in time by reading the data on the display screen to ensure that the predetermined burial depth requirement is met.

[0047] The distance measurement module switch 3-3 is used to control the start and stop of the laser distance measurement probe.

[0048] The control module is responsible for processing signals from the laser rangefinder and calculating accurate distance data. It also transmits this calculated data to the distance display for display and controls the start and stop of the laser rangefinder based on commands from the rangefinder module. The control module typically uses a single-chip microcomputer as its core component to ensure efficient and accurate data processing.

[0049] The charging port is set on one side of the shell to provide power support for the laser ranging module;

[0050] The device features a laser ranging module fixed to the power head, which uses laser ranging technology to monitor and display the buried depth of the grounding pin in real time. The module calculates distance by emitting a laser beam and receiving the reflected signal, offering accurate measurement and rapid response. Construction personnel can adjust the insertion depth based on the data displayed on the display to ensure the grounding pin meets the required buried depth.

[0051] Digital Display: The laser distance measurement module is integrated with the digital display system to visually display the measurement results in digital form on the power head's grip or other convenient location. This digital display not only improves measurement accuracy, but also facilitates operation and monitoring by construction personnel, reducing the possibility of human error.

[0052] In summary, the laser ranging module 3, through the coordinated operation of its various components, achieves accurate measurement and intuitive display of the buried depth of the grounding pin body. This not only improves construction efficiency and quality, but also provides a strong guarantee for the safe operation of the transmission and distribution line.

[0053] Preferably, Figures 1-2 、 Figure 5 As shown, the bottom of the grounding needle 2-1 is configured as a spiral drill bit.

[0054] The spiral shape of the grounding needle's base effectively cuts into the soil, reducing resistance during insertion. The sharp edge and rotational force of the auger bit effectively penetrate hard layers in the soil, such as rock and gravel, ensuring the grounding needle is smoothly screwed deep into the soil. To cope with tough geological conditions, auger bits are typically made of high-strength, corrosion-resistant materials such as stainless steel or alloy steel to ensure durability and stability during use.

[0055] The electric drive allows the auger to rotate rapidly and penetrate deep into the soil, significantly improving the installation efficiency of the grounding pins. Compared to traditional manual installation methods, the electric drive significantly reduces the labor intensity of construction workers and makes the operation more convenient.

[0056] Compared with traditional impact or excavation installation methods, the design of the spiral drill bit can reduce damage to the surrounding soil and underground pipelines, reducing construction risks.

[0057] In summary, the bottom of the grounding pin 2-1 is set as a spiral drill bit and works under electric drive, which can easily cope with hard geological conditions, ensure that the grounding pin body can be screwed into the soil smoothly and quickly, and provide reliable protection for the safe operation of various electrical equipment and systems.

[0058] Preferably, Figures 1-2 、 Figure 5 As shown, a scale line is set on the grounding pin 2-1.

[0059] In the grounding device, a scale line is set on the grounding pin 2-1 and used in combination with a laser ranging module to further improve the reliability and accuracy of the buried depth of the grounding pin.

[0060] Manual Reading of the Scale: Intuitive: The scale is printed directly on grounding pin 2-1, allowing workers to visually determine the grounding pin's depth by observing its position. This simple and direct method requires no additional equipment or techniques. Convenient Operation: Without the need for precise measurement or equipment, workers can quickly check whether the grounding pin has reached the required depth by observing the scale.

[0061] Laser ranging module, high precision: The laser ranging module calculates distance by emitting a laser beam and receiving its reflected signal, offering high accuracy and fast response. It provides accurate burial depth data, ensuring the stability and reliability of the grounding system. Real-time performance: The laser ranging module measures the burial depth of the grounding pin in real time and displays the results on a display. Construction personnel can adjust the grounding pin's insertion depth based on the displayed data to ensure the required burial depth is achieved. Reduced human error: Compared to manual readings, the laser ranging module automatically calculates and displays measurement results, reducing the potential for human error. This helps improve the accuracy and reliability of grounding system installation.

[0062] The combined use of the scale lines and the laser ranging module offers complementary advantages: the scale lines provide intuitive burial depth information, while the laser ranging module provides precise measurement results. This combined use of the two can fully leverage their respective strengths, improving the accuracy and reliability of depth determination. Dual Verification: During construction, construction personnel can first use the scale lines for a preliminary assessment, and then use the laser ranging module for precise measurement. This provides dual verification of burial depth, ensuring the quality of the grounding system installation. In some unusual geological conditions, such as high soil moisture or impurities such as rocks, the laser ranging module may be affected. In these cases, the scale lines can serve as an auxiliary tool to help construction personnel determine the depth of the grounding pins.

[0063] In summary, adding scale lines to grounding pin 2-1 and combining it with a laser ranging module can further improve the reliability and accuracy of grounding pin depth determination. This design combines the advantages of manual reading and laser ranging, providing more comprehensive and reliable support for grounding system installation.

[0064] Preferably, Figures 1-2 、 Figure 4 As shown, a protective cover 4 is further provided on the grounding pin 2 - 1 , and the protective cover 4 is arranged on the upper side of the grounding wire lug 2 - 2 .

[0065] The protective cover 4 provided on the grounding pin 2-1 is located on the upper side of the grounding wire lug 2-2. This design improves the safety of the device and prevents accidental injury to operators during operation or maintenance.

[0066] The main function of the protective cover is to protect the operator from the protrusions at the connection between the grounding pin and the grounding wire. These protrusions may become a safety hazard during operation or maintenance of the grounding device, and the presence of the protective cover can effectively isolate these potential sources of danger.

[0067] The protective cover is arranged on the upper side of the grounding wire lug 2-2. This position selection fully considers the operator's range of activities and possible contact parts, ensuring the maximum protection effect.

[0068] In summary, the protective cover 4 provided on the grounding pin 2 - 1 plays an important role in improving the safety of the device and preventing accidental injury to operators.

[0069] Preferably, Figures 1 to 3 As shown, the laser ranging module 3 is fixedly arranged between the motor 1-3 and the power battery 1-2.

[0070] Placing the laser ranging module 3 between the motor 1-3 and the power battery 1-2 can effectively utilize the free space inside the device, rationally arrange the layout, reduce the volume and weight of the entire device, and improve portability and installation flexibility.

[0071] Preferably, Figures 1 to 3 As shown, the power battery 1-2 is a detachable lithium battery.

[0072] The application of removable lithium battery in the electric digital display screw grounding device provides a convenient energy solution. The main advantages of this design are:

[0073] 1. Easy to replace: When the battery is exhausted or its performance degrades, the user can quickly replace the battery without the need for a complicated charging process. This is particularly practical for outdoor grounding installations. No need to find a charging power source, just carry a few spare batteries.

[0074] 2. Easy maintenance: The removable battery is easy to maintain and inspect, which helps to detect and solve problems in time and ensure the reliability of the equipment.

[0075] 3. Cost-effectiveness: Compared to built-in batteries, removable batteries may be more economical in the long run. Users can purchase additional batteries as needed instead of replacing the entire device at the end of the battery life.

[0076] Preferably, the length of the grounding pin 2 - 1 is 80 cm.

[0077] The electric digital display spiral grounding device used in 10kV to 110kV transmission and distribution lines features an 80cm grounding pin, designed to meet the needs of on-site operations. The top surface of the grounding electrode should be buried at a depth of no less than 0.6m to ensure effective and safe grounding. The length of the grounding pin, combined with the appropriate burial depth, ensures effective contact with the earth, providing stable grounding performance.

[0078] In general, the 80cm grounding pin length is a practical choice that comprehensively considers on-site construction convenience and grounding effect, aiming to ensure that the grounding device of the transmission and distribution line can operate safely and effectively.

[0079] The preferred embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in this field without departing from the purpose of the present invention.
