Description

Technical Field

[0001] The present invention relates to the technical field of electrical engineering, and in particular to a detection device and method for electrical engineering. Background Art

[0002] Electrical work usually refers to professional technical operations and engineering practices related to power systems, equipment installation, operation, maintenance and fault detection; this type of work covers all aspects of power production, transmission, distribution and use, and involves the design, installation, commissioning, operation and maintenance and safety management of electrical equipment, and is widely used in industries, construction, transportation and daily life. Electrical work requires technicians to master not only basic knowledge such as power principles, electronic technology, and automatic control, but also practical operation skills and the ability to deal with complex faults.

[0003] The detection device in electrical engineering is an important tool to ensure the safe and reliable operation of electrical equipment. Among them, measurement and detection is one of the core links. It mainly uses various professional instruments to accurately measure and evaluate the key parameters of the electrical system to determine the health status and operational reliability of the equipment. In the measurement and detection, the measurement of current and voltage is the most basic. Through the use of ammeters, voltmeters and other equipment, we can quickly understand the power supply status of the circuit, ensure that the current and voltage are maintained within the rated range, and prevent problems such as overload or undervoltage. At the same time, the measurement of impedance and insulation resistance is particularly important. Impedance measurement determines whether the circuit has short circuit, open circuit or abnormal load by analyzing the impedance value of the circuit or equipment, while the measurement of insulation resistance can detect the insulation performance of the equipment to prevent safety hazards such as leakage and short circuit. The measurement of grounding resistance is an important means to ensure the safe grounding of equipment. By detecting the impedance of the grounding system, it is ensured that the power system can quickly discharge the current to the ground in the event of a fault to protect the safety of personnel and equipment.

[0004] Although the detection devices in electrical engineering play an important role in ensuring the safe operation of electrical equipment, there are still some shortcomings in the use of detection instruments in the prior art. Usually, when testing electrical systems, technicians rely on handheld detection instruments, such as ammeters, voltmeters, insulation resistance testers, etc. Although this handheld operation is easy to carry and measure quickly, it is easy to cause unstable operation due to the inability to achieve fixed placement of the instrument, especially in complex working environments (such as high-altitude operations, narrow spaces or long-term detection tasks). Handheld operation not only increases the workload of technicians, but also affects the measurement accuracy and reliability of the results. In addition, long-term handheld operation can easily lead to operator fatigue and the risk of misoperation. Especially when testing high-voltage equipment, it is even more necessary to ensure the stability and safety of the measuring instrument, otherwise it is easy to cause safety accidents or equipment damage, especially in the fixed placement of the instrument. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a detection device and method for electrical engineering, which solves the problem that the detection instruments in the prior art cannot be fixedly placed, especially the problems of insufficient stability, reduced measurement accuracy and operator fatigue caused by handheld operation in complex working environments.

[0014] The present invention also provides a method for using the detection device for electrical engineering, comprising the following steps: S1. When the detection device is installed and fixed as a whole, the bottom shell is driven to move downward by holding the lower protective shell and the upper protective shell. When the bottom shell moves downward, it will drive the extrusion block to move to the position to be fixed, so that the extrusion block is squeezed by the position to be fixed, and the extrusion block will move upward when it is squeezed. When the extrusion block is squeezed, it will drive the limit plate to move upward at the same time, so that the limit plate slides into the middle of the clamping groove. After the limit plate slides into the middle of the clamping groove, the two tension springs will pull the two connecting blocks to move toward each other. When the two connecting blocks move, they will drive the two clamping plates to move at the same time, and the two clamping plates can fix the device as a whole when they move; S2. When the detection device is disassembled as a whole, the two connecting plates are manually pressed to move toward the opposite sides. When the two connecting plates move at the same time, the moving block is driven to move, and when the moving block moves, the connecting block and the clamping plate are driven to move outward. When the clamping plate moves, it will be separated from the clamping groove. When the clamping plate is separated from the clamping groove, the extrusion block can be pushed downward under the action of spring 1, so that the limit plate and the two clamping plates are clamped and limited, so that the detection device can be disassembled as a whole; S3. When the detector vibrates or is hit, the detector will squeeze the buffer plate. When the buffer plate is squeezed, it will drive the upper buffer shell to move downward. When the upper buffer shell moves downward, it will squeeze the spring three. When the spring three is squeezed, it will drive the adjustment plate to move downward at the same time. When the adjustment plate is squeezed, it will drive the buffer ring to move downward at the same time through the buffer column. When the buffer ring moves downward, it will squeeze the spring four, so that the detector as a whole can be buffered; S4. When the detection device is carried as a whole, the pull ring is pulled to drive the pull rope to move. When the pull rope moves, the movable plate is pulled to move downward, and when the movable plate moves, the spring 5 is squeezed. When the movable plate squeezes the spring 5, it drives the card block to slide into the interior of the fixed shell. When the card block moves, it will be separated from the card slot. After the card block is separated from the card slot, the length of the adjustment belt can be adjusted, and the shoulder strap and the adjustment belt can be separated, so that the detection device can be carried as a whole; S5. When using the detection device, insert the two detection wires into the position to be detected, and then use the detector to detect it. After the detection is completed, the detector will display the corresponding value, allowing the operator to observe or record the value. When further detection or detection of small electrical appliances is required, it can be used for detection through a handheld multimeter.

[0015] The present invention provides a detection device and method for electrical engineering, which has the following beneficial effects: 1. The present invention drives the bottom shell to move to the required fixed position through the lower protective shell and the upper protective shell. After moving to the required position, the extrusion block can be squeezed to make the extrusion block slide into the interior of the bottom shell. When the extrusion block is moved and squeezed, the extrusion block will squeeze the spring 1 and drive the limit plate to move. When the limit plate moves, it can easily slide into the interior of the clamping groove, so that it can be conveniently clamped and fixed under the action of the clamping groove. After the limit plate slides into the middle of the clamping groove, the tension spring will pull the two connecting blocks to move. When the two connecting blocks move at the same time, they will drive the clamping plate and the anti-slip strip to move, so as to facilitate the clamping of the required fixed position, and at the same time, it is convenient for operators to perform detection work, and it improves work efficiency and reduces the labor intensity of operators.

[0016] 2. The present invention squeezes the upper buffer shell through the buffer plate, and when the upper buffer shell is squeezed, it drives the spring three and the adjusting plate to move downward at the same time. When the adjusting plate moves downward, it drives the buffer column to move downward at the same time. When the buffer column moves downward, it squeezes the buffer ring. When the buffer ring is squeezed, it squeezes the spring four. Therefore, under the action of the spring four and the spring three, the detector can be buffered, preventing the detector from being affected or damaged by external vibration or impact, thereby increasing the overall service life of the device and making it convenient for operators to use.

[0017] 3. The present invention drives the pull rope to move by pulling the pull ring, and when the pull rope moves, it will pull the movable plate to move, and when the movable plate moves, it will squeeze the spring five, and when the movable plate squeezes the spring five, it will drive the card block to move, and when the card block moves, it will be separated from the card slot. When the card block is separated from the card slot, the adjustment belt can be adjusted conveniently, and the shoulder strap and the adjustment belt can be separated conveniently, so that the operator can work conveniently, thereby improving work efficiency.

When the detection device is installed and fixed as a whole, the bottom shell (13) is driven to move downward by holding the lower protective shell (1) and the upper protective shell (2). When the bottom shell (13) moves downward, it drives the extrusion block (15) to move to the position to be fixed, so that the extrusion block (15) is squeezed by the position to be fixed, and the extrusion block (15) moves upward when being squeezed. When the extrusion block (15) is squeezed, it drives the limit plate (25) to move upward at the same time, so that the limit plate (25) slides into the middle of the clamping groove (24). When the limit plate (25) slides into the middle of the clamping groove (24), the two tension springs (22) pull the two connecting blocks (17) to move toward the opposite sides. When the two connecting blocks (17) move, they drive the two clamping plates (18) to move at the same time. When the two clamping plates (18) move, the device as a whole can be fixed; S2. When the detection device is to be disassembled as a whole, the two connecting plates (19) are manually pressed to move toward the opposite sides. When the two connecting plates (19) move at the same time, the moving block (20) is driven to move. When the moving block (20) moves, it drives the connecting block (17) and the clamping plate (23) to move outward. When the clamping plate (23) moves, it is separated from the clamping groove (24). After the clamping plate (23) is separated from the clamping groove (24), the extrusion block (15) can be pushed downward under the action of the spring 1 (26), so that the limit plate (25) and the two clamping plates (23) are clamped and limited, so that the detection device can be disassembled as a whole. S3. When the detector (10) vibrates or is impacted, the detector (10) will squeeze the buffer plate (9). When the buffer plate (9) is squeezed, it will drive the upper buffer shell (31) to move downward. When the upper buffer shell (31) moves downward, it will squeeze the spring three (35). When the spring three (35) is squeezed, it will drive the adjustment plate (36) to move downward at the same time. When the adjustment plate (36) is squeezed, it will drive the buffer ring (38) to move downward at the same time through the buffer column (37). When the buffer ring (38) moves downward, it will squeeze the spring four (39), so that the detector (10) can be buffered as a whole. S4. When the detection device is carried as a whole, the pull ring (47) is pulled to drive the pull rope (46) to move. When the pull rope (46) moves, it pulls the movable plate (43) to move downward. When the movable plate (43) moves, it squeezes the spring five (44). When the movable plate (43) squeezes the spring five (44), it drives the card block (41) to slide into the interior of the fixed shell (40). When the card block (41) moves, it will be separated from the card slot (42). After the card block (41) is separated from the card slot (42), the length of the adjustment belt (4) can be adjusted. At the same time, the shoulder strap (3) and the adjustment belt (4) can be separated, so that the detection device can be carried as a whole. S5. When the detection device is used, two detection wires (14) are inserted into the positions to be detected, and then the detection device (10) is used to detect the detection device. After the detection is completed, the detection device (10) will display the corresponding value, so that the operator can observe or record the value. When further detection is required or small electrical detection is required, the handheld multimeter (12) can be used to detect the detection device.
