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

[0003] Voltage monitoring is a crucial aspect of power system operation. It effectively identifies and prevents abnormal conditions in the power system. When the voltage deviates from the normal operating range, it may lead to equipment damage, energy waste, or even large-scale power outages. By monitoring voltage changes in real time and issuing timely alarms in abnormal situations, it can provide important support for the maintenance and management of the power system. Although existing power monitoring equipment can be fixed to cables, it lacks comprehensive external protection devices. Since most of the detection equipment is connected to the internal wiring of the cable by piercing, the monitoring equipment is easily damaged by accidental contact with external forces after installation, thus leading to the failure of the monitoring equipment.

[0004] Therefore, it is necessary to invent a voltage monitoring and protection device to solve the above problems. Utility Model Content

Detailed Implementation

[0020] 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.

[0021] This utility model provides, for example Figures 1-7 The voltage monitoring and protection device shown includes a cable body 1. A detection device 2 is fixedly installed on the outer surface of the cable body 1. The detection device 2 is wired to a control device 3. Two first protective covers 4 are provided on the outer surface of the cable body 1 for wrapping the detection device 2 and the control device 3. Two second protective covers 5 are provided on the outer surface of the cable body 1 for wrapping the detection device 2 and the control device 3. A reinforcing component 7 is provided on one side of the two second protective covers 5 to improve the connection strength between the second protective covers 5 and the cable body 1. The two reinforcing components 7 include second connecting members 701 fixedly connected to the second protective covers 5. 1. The second connector 701 is fixedly connected to the cable body 1 by bolts. A support plate 702 is fixedly connected to one side of the second connector 701. A right angle plate 703 is fixedly connected to the top of the support plate 702. A limit hole 7030 is symmetrically opened on one side of the right angle plate 703. A crossbar 704 that is inserted into the limit plate 7040 is symmetrically movably passed through the support plate 702. The limit plate 7040 is sleeved on the outer peripheral surface of the two crossbars 704. A second compression spring 705 is sleeved on the outer peripheral surface of the two crossbars 704, with its two ends abutting against the limit plate 7040 and the right angle plate 703 respectively. A clamping block 706 with an arc-shaped inner surface is fixedly connected to the other end of the two crossbars 704.

[0022] The first protective cover 4 and the second protective cover 5 constitute a protective structure for the detection equipment 2 and the control equipment 3. By wrapping them, they can effectively block external physical impacts, dust, moisture, and other damage to the equipment, providing a relatively safe and stable operating environment for the detection equipment 2 and the control equipment 3, and ensuring the normal operation of the equipment. The reinforcing component 7 is bolted to the cable body 1 through the second connector 701, providing a basic connection for the second protective cover 5. On this basis, by utilizing the cooperation of the crossbar 704, the limiting plate 7040, the second compression spring 705, and the clamping block 706, when installed, the crossbar 704, under the elastic force of the second compression spring 705, makes the clamping block 706 tightly fit against the cable body 1. By increasing the friction and clamping force with the cable body 1, the connection stability between the second protective cover 5 and the cable body 1 is further enhanced, preventing the second protective cover 5 from loosening or shifting under the influence of external factors, and ensuring the protective effect on the internal equipment.

[0023] A vertical plate 707 is inserted into the top of the right-angle plate 703. A vertical hole 7070 is opened in the middle of the vertical plate 707. A limiting block 708, which is fixedly connected to the right-angle plate 703, is slidably connected to the vertical hole 7070. The bottom end of the vertical plate 707 is inclined. The bottom surface of the vertical plate 707 abuts against the top side of the limiting plate 7040. The vertical plate 707 and the limiting block 708 cooperate to limit and guide the vertical plate 707 in the vertical direction to ensure its stable sliding. The inclined surface at the bottom end of the vertical plate 707 abuts against the top of the limiting plate 7040. During installation or disassembly, by pressing down the vertical plate 707, the inclined surface pushes the limiting plate 7040, thereby driving the crossbar 704 and the clamping block 706 to move, realizing convenient operation of clamping or releasing the cable body 1.

[0024] A horizontal plate 501 is fixedly connected inside the second protective cover 5. Inside the horizontal plate 501, below the horizontal plate 501, a mounting block 502 for fixing the control device 3 is fixedly installed. The horizontal plate 501 provides a mounting base for the mounting block 502. The mounting block 502 can position and fix the control device 3, so that the control device 3 remains stable inside the second protective cover 5.

[0025] A quick-release assembly 6 for easy disassembly of the first protective cover 4 is provided on one side. A rectangular hole 401 is provided inside the first protective cover 4. A first connector 402 is fixedly connected to one side of the first protective cover 4. The two first protective covers 4 are connected to each other by bolts through the first connector 402. The quick-release assembly 6 includes a rectangular frame 601 fixedly connected to the first protective cover 4. A rod 602 is movably inserted through one side of the rectangular frame 601. A toggle block 603 is fixedly inserted through the rod 602 and slidably connected to the rectangular frame 601. A first compression spring 604 is sleeved on the outer circumferential surface of the rod 602, with its two ends abutting against the toggle block 603 and the rectangular frame 601 respectively. The rectangular hole 401 is inserted into the horizontal plate 501. An insertion hole 5010 is provided at the end of the horizontal plate 501, and the insertion hole 5010 is inserted into the rod 602.

[0026] The first connector 402, in conjunction with the bolt, establishes a preliminary connection between the two first protective covers 4, forming initial protection for the detection equipment 2 and the control equipment 3. The rectangular hole 401, inserted into the horizontal plate 501, allows for preliminary positioning of the first protective cover 4 and the second protective cover 5, ensuring accurate installation and enhancing the tightness of the connection between the first protective cover 4 and the second protective cover 5. The quick-release assembly 6, based on this, provides a quick-release function. The rectangular frame 601 provides installation space and support structure for the insertion rod 602, the toggle block 603, and the first compression spring 604. When the first protective cover 4 is installed in place, the first compression spring 604 pushes the insertion rod 602 into the horizontal plate 5. In the socket 5010 of 01, the first protective cover 4 and the second protective cover 5 are quickly locked together. When disassembly is required, by moving the toggle block 603, the elastic force of the first compression spring 604 is overcome, and the plug rod 602 is pulled out of the socket 5010, thereby quickly separating the first protective cover 4 and the second protective cover 5. The plug rod 602 is inserted into the socket 5010, further realizing the quick locking and stable connection of the first protective cover 4 and the second protective cover 5. The operation is simple and convenient. When inspecting, maintaining or replacing internal equipment, there is no need to cumbersomely disassemble multiple bolts. The first protective cover 4 can be quickly separated by operating the quick-release component 6, which improves the efficiency of equipment maintenance and reduces maintenance time and labor costs. Multiple reinforcing rods 8 are fixedly installed inside the two first protective covers 4 and the second protective cover 5 to improve the support strength. The reinforcing rods 8 are distributed inside the first protective cover 4 and the second protective cover 5, which can enhance the overall structural strength and rigidity of the protective cover, making it less likely to deform or break when the protective cover is subjected to external impact, compression and other external forces, effectively improving the protective performance of the protective cover, better protecting the internal detection equipment 2 and control equipment 3, and extending the service life of the entire protective device.

[0027] The working principle of this utility model is as follows: The detection device 2 is fixedly installed on the outer surface of the cable body 1, and the wires connecting the detection device 2 and the control device 3 are completed. Then, two second protective covers 5 are installed around the detection device 2 and the control device 3 on the cable body 1. The second protective covers 5 are initially fixed to the cable body 1 using bolts on the second connector 701. Next, the vertical plate 707 is pressed down, and the inclined surface at the bottom of the vertical plate 707 pushes the limiting plate 7040, causing the horizontal bar 704 and the clamping block 706 to move towards the cable body 1 until the clamping block 706 is tightly attached to the cable body 1. At this time, the second compression spring 705 is compressed, and its elasticity generates a large frictional force and clamping force between the clamping block 706 and the cable body 1, completing the stable connection between the second protective cover 5 and the cable body 1, enhancing the installation stability of the second protective cover 5. Finally, the two first protective covers 4 are connected via the first connector 40. 2. The first protective cover 4 is initially connected to the bolts, forming initial protection for the equipment. At the same time, the rectangular hole 401 on the first protective cover 4 is inserted into the horizontal plate 501 inside the second protective cover 5, realizing the initial positioning of the first protective cover 4 and the second protective cover 5 and enhancing the tightness of their connection. After the first protective cover 4 is installed in place, the first compression spring 604 is compressed by pushing the actuating block 603. Under the elastic force of the spring, after the insertion rod 602 is inserted into the insertion hole 5010 of the horizontal plate 501, the actuating block 603 is released. Under the elastic force of the first compression spring 604, the insertion rod 602 is inserted into the insertion hole 5010, thereby realizing the rapid locking of the first protective cover 4 and the second protective cover 5. At this point, the entire protective device is installed. The first protective cover 4 and the second protective cover 5 form a protective structure, blocking external physical impacts, dust, water vapor, etc. from damaging the detection equipment 2 and the control equipment 3, providing a stable operating environment for the equipment.

[0028] During the operation of the device, the internal reinforcing rod 8 enhances the structural strength and rigidity of the first protective cover 4 and the second protective cover 5, resists external impacts and compression, prevents the protective cover from deforming or breaking, and continuously ensures the safety of the internal equipment. If it is necessary to inspect, maintain or replace the detection equipment 2 or the control equipment 3, simply move the toggle block 603 in the quick release assembly 6 to overcome the elastic force of the first compression spring 604 and pull the plug rod 602 out of the plug hole 5010 to quickly separate the first protective cover 4 without disassembling multiple bolts, which greatly improves the equipment maintenance efficiency and reduces maintenance time and labor costs.

[0029] It should be noted that the diameters of the detection device 2, control device 3, first protective cover 4, and second protective cover 5 in this embodiment are not limited.

[0030] 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. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
