Technical Field
[0001] This utility model belongs to the field of magnetic field collector technology, specifically relating to a portable U-shaped magnetic field collector. Background Technology
[0002] Cable phase detection is an important daily task in power systems. Traditional cable phase detection methods typically require power outages and the use of specialized testing instruments to contact the cable. This is not only complex and time-consuming, but also poses significant safety risks under high-voltage environments. With continuous technological advancements, non-contact cable phase detection devices utilizing the principle of magnetic field induction have gradually emerged. These devices can safely perform phase detection in energized environments, improving both work efficiency and safety.
[0003] While existing magnetic field phase acquisition devices have addressed some of the safety hazards and operational complexity of contact detection, some current devices suffer from insufficient compactness and ease of use. In existing designs, some screws and interfaces are exposed, allowing moisture, dust, and other external factors to enter and affect the stability and lifespan of electronic components. The presence of numerous exposed metal parts in some devices increases the risk of accidental electric shock. Furthermore, the inefficient design of some devices' openings complicates cable routing and reduces work efficiency.
[0004] In view of this, we propose a portable U-shaped magnetic field collector. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] The following is combined with Figure 1-5 This application will be described in further detail.
[0025] This application discloses a portable U-shaped magnetic field collector, including a collector housing 1, a telescopic insulating rod 3, and a handheld device 15 with a display screen 17.
[0026] The collector housing 1 is provided with a U-shaped opening 2 for the cable to be inserted. The collector housing 1 is composed of an outer shell 101 and a bottom cover 102. The cavity enclosed by the outer shell 101 and the bottom cover 102 is provided with a U-shaped probe 4 made of a material with high magnetic permeability for sensing the magnetic field around the cable.
[0027] The housing 101 has an internally threaded post, and the bottom cover 102 is threadedly connected to the internally threaded post via a concealed screw. A cover plate 18, which is threadedly connected to the housing 101, is inserted into the upper limit of the bottom cover 102. The internally threaded post provides additional mechanical strength, making the connection between the housing 101 and the bottom cover 102 more secure and ensuring the stability of the overall structure of the data collector. The design of the concealed screw and the threaded cover plate 18 provides a more sealed environment, helping to prevent damage to the internal electronic components from external factors such as moisture and dust. The screws are hidden internally, reducing exposed metal parts, lowering the risk of accidental electric shock, and improving safety during use.
[0028] The external threaded connector 301 at the front end of the telescopic insulating rod 3 is screwed into the insulating interface 103 on the outer shell 101, and the tail end of the telescopic insulating rod 3 is fixedly sleeved with an insulating handle 302.
[0029] This portable U-shaped magnetic field collector is used for phase acquisition inside cable boxes. When in use, hold the telescopic insulating rod 3 connected to the collector housing 1, place the magnetic field collector on the cable, and let the cable pass through the U-shaped opening 2 in the middle of the fork to acquire the phase information of a single cable. Then, measure the other two cables in sequence.
[0030] When measuring the phase of an elbow joint or cable branch box elbow joint of a high-voltage indoor operating cable, connect a telescopic insulating rod 3 to the bottom of the magnetic field phase acquisition device housing 1 and insert it into the insulating interface 103 of the cable elbow joint. The arrow marking 12 on the side of the acquisition device indicates the direction of the cable's operating current.
[0031] This portable U-shaped magnetic field acquisition device, using a telescopic insulating rod 3, allows for safe cable phase acquisition in energized environments, avoiding the risk of electric shock from direct contact with high-voltage cables. The device's compact and lightweight design makes it easy for personnel to carry and operate, especially in space-constrained high-voltage indoor environments. The U-shaped opening 2 allows cables to be easily threaded through, enabling phase information acquisition without complex operations. The U-shaped probe 4, made of a high-permeability material, effectively senses the magnetic field around the cable, providing accurate phase information. When measuring the phase information of multiple cables sequentially, the device's position can be quickly changed to improve work efficiency. The acquisition device is suitable not only for phase acquisition inside ordinary cable boxes but also for phase determination of elbow joints or cable branch box elbow joints in high-voltage indoor environments, offering a wide range of applications. Because the acquisition device can be quickly installed and removed, it reduces interference and interruptions to normal operation during cable inspection and maintenance.
[0032] The cavity enclosed by the outer casing 101 and the bottom cover 102 also houses a circuit board and a battery 5. The circuit board integrates a microprocessor 6 electrically connected to the U-shaped probe 4 via a connector, a wireless communication module A7 connected to the antenna 19 on the outer casing 101, and a memory module 8 for storing processed data or program code. The handheld device 15 integrates a corresponding wireless communication module B16. After the wireless communication module A7 on the circuit board inside the collector casing 1 successfully pairs with the wireless communication module B16 inside the handheld device 15, the collected magnetic field phase data is wirelessly transmitted to the handheld device 15, and the phase determination result is displayed on the display screen 17.
[0033] The data collector housing 1 is equipped with a power switch 9, a status indicator light 10, and a charging indicator light 11. Arrow markers 12 are located on both sides of the front end of the housing 1. A charging interface 13 is also embedded in the side of the housing 1. The embedded charging interface 13 is designed for convenient charging without disassembling the data collector or using special charging equipment. The charging interface 13 is designed with a protection circuit to prevent overcharging, over-discharging, and short circuits, ensuring the safety of the battery 5 and extending its lifespan. The power switch 9 allows users to easily turn the device on and off. The status indicator light 10 provides real-time feedback on the device's status, such as operating status and battery level. The charging indicator light 11 provides an intuitive display of the charging status during charging, allowing users to easily understand the charging progress.

[0035] Status indicator light 10: Red light flashing intermittently indicates power-on, green light flashing intermittently indicates successful communication.
[0036] Charging indicator light 11: Red light indicates charging, green light indicates fully charged.
[0037] Arrow 12 indicates the direction of the operating current in the cable, helping users to correctly install and use the data acquisition unit and ensure data accuracy. Clear labeling reduces the possibility of misoperation and improves operational safety.
[0038] The integration of the microprocessor 6, wireless communication module, and memory module 8 on the circuit board makes the data acquisition unit more compact, reducing its size and weight and improving its portability. The microprocessor 6 enables real-time data processing, improving data accuracy and timeliness. The memory module 8 provides data storage functionality, saving the acquired data for subsequent analysis or transmission. The built-in battery 5 provides a stable power supply, ensuring the data acquisition unit can operate for extended periods without an external power source.
[0039] The collected magnetic field phase data can be directly viewed on the display screen 17, improving the user experience. The wireless communication module B16 allows the handheld device 15 to communicate remotely with the data acquisition unit, enabling users to operate from a safe location and reducing risks. The handheld device 15 is easy to carry, allowing for data reading and operation anytime, anywhere, thus improving work efficiency.
[0040] The U-shaped probe 4 uses a material with high magnetic permeability to sense the magnetic field around the cable and converts the magnetic field signal into an electrical signal. The microprocessor 6 receives the converted electrical signal from the U-shaped probe 4, processes and analyzes the data, and determines the phase information of the cable. The wireless communication module A7 wirelessly transmits the phase data processed by the microprocessor 6 to the wireless communication module B16 in the handheld device 15. The memory module 8 stores the processed data or program code for later use or analysis. The power switch 9, status indicator 10, and charging indicator control the power on and off, and display the current status and charging status of the device.
