[0002] In modern society, the stability and reliability of electricity supply are crucial for economic development and social life. With the continuous growth of electricity demand and the increasing complexity of power grid structures, the challenges facing power systems are becoming increasingly severe. Against this backdrop, ensuring the continuity and security of electricity supply has become an important issue.

[0003] Voltage monitoring is a crucial aspect of power system operation, effectively identifying and preventing abnormal conditions. When voltage deviates from the normal operating range, it can lead to equipment damage, energy waste, and even large-scale power outages. By monitoring voltage changes in real time and issuing timely alarms in abnormal situations, it provides vital support for power system maintenance and management. In industrial and residential electricity use, voltage fluctuations can negatively impact precision instruments in industrial production lines or electronic devices in homes. By deploying voltage monitoring and alarm devices, timely measures can be taken when voltage anomalies are detected, protecting equipment from damage and reducing economic losses. Developing a voltage monitoring and alarm device for power supply protection that integrates real-time voltage monitoring, data analysis, and anomaly alarm functions can effectively improve the stability and security of the power grid.

[0004] Traditional voltage monitoring devices are cumbersome to operate and difficult to adapt quickly to power lines of different specifications and complex measurement environments, resulting in low on-site work efficiency. In terms of measurement accuracy, some devices cannot accurately control the probe puncture position and depth, making it difficult to adapt to the measurement needs of cables of different diameters and affecting data accuracy.

[0005] Therefore, it is necessary to invent a voltage monitoring device for power supply to solve the above problems. Utility Model Content

[0007] To achieve the above objectives, this utility model provides the following technical solution: a voltage monitoring device for power supply, comprising a handle body, wherein a first limiting hole is provided inside the handle body, and two pressure blocks are installed in the first limiting hole. A horizontal plate is movably inserted through both pressure blocks, and the horizontal plate movably penetrates the handle body. A piercing clamping trigger, which abuts against the pressure blocks, is hinged to one side of the handle body at the first limiting hole. A first return spring is sleeved on the outer circumferential surface of the horizontal plate within the first limiting hole, and both ends of the first return spring abut against the pressure blocks and the handle body, respectively. A second limiting hole is provided inside the handle body on the side near the first limiting hole, and a limiting groove communicating with the second limiting hole is provided above the second limiting hole.

[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] This utility model provides, for example Figures 1-4 The voltage monitoring device for power supply shown includes a handle body 1. A first limiting hole 101 is provided inside the handle body 1. Two pressure blocks 102 are installed inside the first limiting hole 101. A horizontal plate 3 movably passes through both pressure blocks 102 and the handle body 1. A piercing and clamping trigger 2, which abuts against the pressure blocks 102, is hinged to one side of the handle body 1 at the first limiting hole 101. A first return spring 103 is fitted inside the first limiting hole 101 on the outer periphery of the horizontal plate 3. The two ends of the first return spring 103 abut against the pressure blocks 102 and the handle body 1, respectively. A second limiting hole 104 is provided inside the body 1 on the side near the first limiting hole 101. A limiting groove 105 communicating with the second limiting hole 104 is provided above the second limiting hole 104. A quick adjustment trigger 106 is movably installed inside the second limiting hole 104 and is movably inserted through the cross plate 3. The top of the quick adjustment trigger 106 is inserted into the limiting groove 105. A second return spring 107 is installed inside the second limiting hole 104 on the side near the end of the quick adjustment trigger 106. The two ends of the second return spring 107 abut against the quick adjustment trigger 106 and the handle body 1, respectively.

[0025] The handle body 1 serves as the handheld operating part of the entire device, facilitating the operator's grip and control of the device. The first limiting hole 101 provides installation space and movement guidance for the pressure block 102 and the horizontal plate 3. The piercing clamping trigger 2, in cooperation with the pressure block 102, pushes the pressure block 102 to move when the operator presses the trigger, thereby achieving clamping or releasing control of the horizontal plate 3. The first return spring 103 provides a restoring force after the piercing clamping trigger 2 is released, so that the pressure block 102 and the horizontal plate 3 return to their initial positions, ensuring the repeatability and stability of the device operation. The second limiting hole 104 and the limiting groove 105 provide installation and movement tracks for the quick adjustment trigger 106. The quick adjustment trigger 106 moves through the horizontal plate 3. By inserting the top end into different positions of the limiting groove 105, the position of the horizontal plate 3 can be quickly adjusted, realizing rapid adjustment of the device's working state. The second return spring 107 resets the quick adjustment trigger 106 after it is released, facilitating the next adjustment operation and ensuring smooth operation of the adjustment function.

[0026] A mounting block 6 is fixedly installed on the top of the handle body 1. A rectangular groove 601 is formed inside the mounting block 6. A third limiting hole 602 communicating with the rectangular groove 601 is formed at the end of the rectangular groove 601. A sliding groove 603 is formed on the outer peripheral surface of the mounting block 6. A limiting frame 10 is slidably mounted on the outer peripheral surface of the mounting block 6 through the sliding groove 603. A second clamping block 9 is fixedly connected to one side of the limiting frame 10 and movably sleeved with the end of the mounting block 6. A limiting post 7 is movably installed inside the third limiting hole 602. A puncture probe 8 is fixedly connected to one end of the limiting post 7. A third return spring 11 is sleeved in the rectangular groove 601 at the outer periphery of the third limiting hole 602 and the puncture probe 8. The two ends of the third return spring 11 are respectively connected to the second clamping block 9. The mounting block 6 abuts against the piercing probe 8 and other components. The mounting block 6 serves as the mounting base for the piercing probe 8 and other components, providing fixation and support. The rectangular groove 601 and the third limiting hole 602 provide installation space and movement guidance for the limiting post 7 and the piercing probe 8. The sliding groove 603 cooperates with the limiting frame 10, allowing the second clamping block 9 to slide along the mounting block 6, facilitating the adjustment of the position of the second clamping block 9 to accommodate objects of different sizes or shapes. The piercing probe 8 is used to pierce the power line or equipment under test to obtain voltage signals. The third return spring 11 provides a return force for the second clamping block 9 and the piercing probe 8, allowing them to return to their initial positions after the measurement or operation is completed. At the same time, it maintains a certain pressure during the measurement process to ensure good contact between the piercing probe 8 and the object under test.

[0027] Both sides of the handle body 1 are fixedly installed with cover plates 4. The cover plates 4 are used to close the two sides of the handle body 1. On the one hand, they protect the internal components of the handle body 1 such as the pressure block 102, the horizontal plate 3, and the first return spring 103, and prevent dust and impurities from entering and affecting the normal operation of the device. The end of the horizontal plate 3 is fixedly connected to the first clamping block 5. The inner side of the first clamping block 5 is arc-shaped. The first clamping block 5 is connected to the horizontal plate 3. Under the control of the piercing clamping trigger 2, the object to be measured can be clamped and fixed. The arc-shaped design of the inner side can better fit the outer surface of the object to be measured, increase the contact area, and improve the stability and reliability of clamping.

[0028] The inner surface of the second clamping block 9 is arc-shaped, and a circular hole 901 for insertion of the puncture probe 8 is provided at the center of the inner surface of the second clamping block 9. The arc-shaped inner surface of the second clamping block 9 cooperates with the first clamping block 5 to clamp the object to be measured in both directions, further enhancing the fixation effect. The circular hole 901 is used to accurately position the puncture probe 8, ensuring that the puncture probe 8 can accurately puncture the target position of the object to be measured. At the same time, it provides a certain support and guidance for the puncture probe 8 during the puncture process, ensuring the accuracy of the measurement. A foldable insulating protective sleeve 14 is fitted on the outer peripheral surface of the horizontal plate 3. The insulating protective sleeve 14 can effectively isolate the horizontal plate 3 from the conductive contact with the outside world, prevent the operator from being electrocuted during use, and ensure personal safety.

[0029] A fixing block 12 is fixedly installed on one side of the limiting frame 10. A scale plate 13 for measuring the movement distance of the limiting frame 10 is fixedly installed on one side of the fixing block 12. The fixing block 12 and the scale plate 13 cooperate with the limiting frame 10. By observing the scale on the scale plate 13, the movement distance of the limiting frame 10 can be intuitively understood, and thus the insertion depth of the piercing probe 8 can be determined. This facilitates precise adjustment by the operator to meet the measurement needs of cables of different diameters, improves the accuracy of measurement and the convenience of operation. A controller 15 is connected to the end of the mounting block 6 through a line. The controller 15 is electrically connected to the piercing probe 8. A buzzer 16 is fixedly installed on one side of the controller 15. The voltage signal acquired by the piercing probe 8 is transmitted to the controller 15. The controller 15 analyzes and processes the voltage signal. When an abnormal voltage is detected, the controller 15 controls the buzzer 16 to sound an alarm, promptly reminding the operator that an abnormal voltage has occurred, so that the operator can quickly take corresponding measures to ensure the safe and stable operation of the power system.

[0030] The working principle of this utility model is as follows: The operator first holds the handle body 1 and controls the movement of the horizontal plate 3 by operating the piercing and clamping trigger 2. When the piercing and clamping trigger 2 is pressed, the piercing and clamping trigger 2 abuts against the pressure block 102 and pushes it to move within the first limiting hole 101. Since both pressure blocks 102 move through the horizontal plate 3 and there is a gap between them, the pressure blocks 102 will also tilt when moving. After tilting, the pressure blocks 102 will generate a large friction force with the surface of the horizontal plate 3, thereby driving the horizontal plate 3 along the first limiting hole 101. As the handle body 1 moves in the direction of movement, the horizontal plate 3 moves, causing the quick adjustment trigger 106 to shift in angle, which in turn squeezes the second return spring 107, causing the quick adjustment trigger 106 to release its restraint on the horizontal plate 3. At this time, the first clamping block 5, which is fixedly connected to the end of the horizontal plate 3, moves accordingly. The first clamping block 5 cooperates with the second clamping block 9 to clamp and fix the power line or equipment under test. When the piercing clamping trigger 2 is released, the pressure block 102 will reset and return to the center under the action of the first return spring 103.

[0031] If the position of the horizontal plate 3 needs to be quickly adjusted, the operator can operate the quick adjustment trigger 106. The quick adjustment trigger 106 is movable through the horizontal plate 3 and its top end is inserted into the limiting groove 105. After the quick adjustment trigger 106 is squeezed, under the action of the limiting groove 105 and the second return spring 107, it will change from an inclined state to a vertical state, thereby releasing the quick adjustment trigger 106 from the horizontal plate 3. Thus, by pressing the piercing clamp trigger 2, the distance between the first clamping block 5 and the second clamping block 9 can be quickly adjusted. When the quick adjustment trigger 106 is released, the second return spring 107 provides a restoring force to return it to its original position, thereby restoring the restraint on the horizontal plate 3.

[0032] After the object to be measured is clamped and fixed, the puncture probe 8, driven by the limiting post 7, passes through the circular hole 901 in the center of the inner side of the second clamping block 9 and punctures the power line or equipment under test. The voltage signal acquired by the puncture probe 8 is transmitted through the line to the controller 15 connected to the end of the mounting block 6. The controller 15 analyzes and processes the voltage signal. If an abnormal voltage is detected, the controller 15 immediately controls the buzzer 16 to sound an alarm to remind the operator to take measures. In addition, the insulating protective sleeve 14 on the outer periphery of the horizontal plate 3 isolates it from external conductive contact to ensure the safety of the operator. The limiting frame 10, the fixing block 12 and the scale plate 13 work together to facilitate the operator to observe the movement distance of the limiting frame 10 and accurately adjust the position of the puncture probe 8 to meet the measurement needs of cables of different diameters.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
