Description

Technical Field

[0001] This invention belongs to the field of monitoring technology, specifically a monitoring device for lightning arresters. Background Technology

[0002] As a critical protective device ensuring the safe operation of equipment in a power system, the real-time monitoring of the operating status of surge arresters is essential. Surge arrester monitors are the core components for realizing this monitoring function, primarily used to collect and feed back the operating parameters of surge arresters in real time, providing data support for the stable operation and maintenance of the power system. With the increasing demands for equipment reliability, ease of maintenance, and service life in power systems, many shortcomings in the structural design of existing surge arrester monitors have become increasingly apparent, making it difficult to meet practical application requirements.

[0003] Existing surge arrester monitors typically consist of an outer casing, a display casing, and a built-in monitoring unit. The rationality of the connection structure design between the display casing and the outer casing directly affects the monitor's assembly efficiency, connection stability, and sealing protection effect. Currently, most monitors use threaded connections or simple snap-fit ​​connections between the display cover and the outer cover. Threaded connections not only require repeated rotation for alignment during assembly, which is cumbersome, but also tend to wear and loosen the threads due to vibration and environmental corrosion after long-term use, affecting the connection's firmness. In view of this, a surge arrester monitor is proposed. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0005] Given the following technical problems in the existing technology: most monitors use threaded connections or simple snap-fit ​​connections for the display cover and outer cover. Threaded connections not only require repeated rotation for alignment during assembly, which is cumbersome, but also are prone to wear and loosening of the threads due to vibration and environmental corrosion after long-term use, affecting the connection's firmness.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a surge arrester monitor, comprising a monitor housing, a monitor display housing, and a monitoring unit; The monitoring unit is housed in the monitor housing and is used for real-time monitoring of the circuit. The monitor display cover is located at the opening of the monitor housing and has numerical display accessories for feeding back real-time data. A connecting seat is provided at the inner edge of the opening of the monitor outer cover. An inner liner is provided on the side of the monitor display cover facing the monitor outer cover. A connecting sleeve is provided on the side of the inner liner facing the monitor outer cover. The connecting sleeve and the connecting seat are fitted together. The connecting seat and the connecting sleeve are configured in a spline manner for precise docking. The connector is equipped with a connection module for limiting the state of the connector sleeve.

[0007] As a preferred technical solution for a surge arrester monitor, grounding connectors are symmetrically arranged on the lower back of the monitor housing, wherein the grounding connectors are used for the overall grounding operation, and surge arrester connectors are arranged on the upper part of the monitor housing, wherein the surge arrester connectors are used for the connection operation between the whole and the surge arrester.

[0008] As a preferred technical solution for a surge arrester monitor, the opening of the monitor's outer casing is provided with a guide rail, and a guide block is telescopically movable in the guide rail. An elastic element is arranged at the middle of the inner edge of the guide block and the guide rail. The guide rail is used to limit the movement range of the guide block. An outer liner is arranged on the part of the guide block facing the monitor's display cover. The outer liner wraps around the outer periphery of the connecting seat, connecting sleeve, and connecting module. The cooperation between the outer liner and the inner liner can further improve the overall sealing effect.

[0009] As a preferred technical solution for a surge arrester monitor, the connection module includes an outer ring cover, a second elastic element, an inner ring cover, and a locking element. The outer ring cover is arranged in parallel on the connecting seat, and the second elastic element is arranged at the middle position between the connecting seat and the outer ring cover. The inner ring cover is movably arranged in the outer ring cover, and the locking element is arranged in the inner ring cover.

[0010] As a preferred technical solution for a surge arrester monitor, the portion of the locking component extending out of the inner and outer ring covers is beveled, and the connecting sleeve has a continuous triangular opening. The triangular opening and the locking component are fitted together, and the beveled position of the locking component makes it difficult for the connecting sleeve and the connecting seat to detach after fitting.

[0011] As a preferred technical solution for a surge arrester monitor, the outer ring cover has a fan-shaped channel one reserved on the side away from the elastic element two. A connecting frame is configured in the fan-shaped channel one. One end of the connecting frame is connected to the inner ring cover, and the other end of the connecting frame is connected to the inner edge of the outer liner. The connecting frame and the outer liner are only in a telescopic relationship and cannot rotate relative to each other.

[0012] As a preferred technical solution for a surge arrester monitor, an elastic element three is configured at the middle position of the locking component and the inner edge of the outer ring cover. The outer ring cover has a reserved vertical channel for the extension and retraction movement of the locking component. The specifications of the vertical channel are compatible with the specifications of the locking component. The vertical channel and the elastic element three ensure that the locking component will not rotate with the inner ring cover.

[0013] As a preferred technical solution for a surge arrester monitor, the inner ring cover has a pre-reserved curved channel, and the overall outline of the curved channel tends to change from the inner edge of the inner ring cover to the outer periphery of the inner ring cover.

[0014] As a preferred technical solution for a surge arrester monitor, the side of the locking member is provided with a cylinder, which is located in a curved channel.

[0015] As a preferred technical solution for a surge arrester monitor, the inner ring cover has a reserved fan-shaped channel two, the specifications of which are larger than the specifications of the locking component, so that when the inner ring cover rotates, it will not drive the locking component to rotate together.

[0016] The beneficial effects of this invention are: 1. The connecting sleeve of the monitor display cover and the connecting seat of the outer cover adopt a spline-type fitting to achieve precise docking and avoid assembly deviation; the matching design of the triangular opening of the connecting sleeve and the slope of the locking piece allows the locking piece to automatically retract when the display cover is inserted, completing the initial fitting without additional operation, making the assembly process easy and efficient; after fitting, the locking piece is engaged with the vertical edge of the triangular opening under the action of the elastic element, completely restricting the position of the display cover, effectively preventing the connecting sleeve from separating from the connecting seat, and ensuring the firmness of the structural connection; 2. The outer liner and inner ring cover are linked by a connecting frame. During maintenance, only the outer liner needs to be rotated. The bending channel and the cylinder will help the locking piece to disengage from the triangular opening, releasing the limit on the display cover and making it easy to remove. The entire disassembly process has no complicated steps and does not require professional tools, which greatly reduces the difficulty and time of maintenance operations and improves the convenience of later maintenance of the equipment. 3. The outer liner that unlocks the display cover has both protective and aesthetic effects. Its operation position is inconspicuous and has a hidden design, making it difficult to be accidentally touched or rotated in non-maintenance scenarios. Structurally, it avoids situations where the locking parts are unlocked, the display cover is loosened or fallen off due to misoperation, ensuring the structural stability and operational safety of the monitor in actual use, and reducing equipment failures and monitoring failures caused by misoperation.

[0027] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0030] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0031] Example, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 A surge arrester monitor includes a monitor housing 100, a monitor display housing 200, and a monitoring unit; the monitoring unit is housed in the monitor housing 100 for real-time monitoring of the circuit, and the monitor display housing 200 is located at the opening of the monitor housing 100, wherein the monitor display housing 200 has numerical display accessories for feeding back real-time data. A grounding connector 101 is symmetrically arranged on the lower back of the monitor housing 100, wherein the grounding connector 101 is used for the overall grounding operation, and a surge arrester connector 102 is arranged on the upper part of the monitor housing 100, wherein the surge arrester connector 102 is used for the connection operation between the whole and the surge arrester. A connecting seat 103 is provided at the inner edge of the opening of the monitor outer cover 100. An inner liner 201 is provided on the side of the monitor display cover 200 facing the monitor outer cover 100. A connecting sleeve 202 is provided on the side of the inner liner 201 facing the monitor outer cover 100. The connecting sleeve 202 and the connecting seat 103 are fitted together. The connecting seat 103 and the connecting sleeve 202 are splined for precise docking.

[0032] Reference Figure 4 and Figure 6The monitor housing 100 has a guide rail 302 reserved at the opening position. A guide block 301 is telescopically movable in the guide rail 302. An elastic element 303 is arranged at the middle of the inner edge of the guide block 301 and the guide rail 302. The guide rail 302 is used to limit the movement range of the guide block 301. An outer liner 300 is arranged on the part of the guide block 301 facing the monitor display cover 200. The outer liner 300 wraps around the outer periphery of the connecting seat 103, the connecting sleeve 202 and the connecting module 400. The cooperation between the outer liner 300 and the inner liner 201 can further improve the overall sealing effect.

[0033] Reference Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 The connecting base 103 is equipped with a connecting module 400 for limiting the state of the connecting sleeve 202. The connecting module 400 includes an outer ring cover 401, an elastic element 402, an inner ring cover 405, and a locking element 406. The outer ring cover 401 is arranged parallel to the connecting base 103. The elastic element 402 is arranged at the middle position between the connecting base 103 and the outer ring cover 401. The inner ring cover 405 is movably arranged in the outer ring cover 401. The locking element 406 is arranged in the inner ring cover 405. The portion of the locking element 406 extending out of the inner ring cover 405 and the outer ring cover 401 is beveled. The upper part has a continuous triangular opening 203, which is fitted with the locking piece 406. The slope of the locking piece 406 makes it difficult for the connecting sleeve 202 and the connecting seat 103 to separate after fitting. The outer ring cover 401 has a fan-shaped channel 404 on the side away from the elastic member 402. The connecting frame 403 is arranged in the fan-shaped channel 404. One end of the connecting frame 403 is connected to the inner ring cover 405, and the other end of the connecting frame 403 is abutted to the inner edge of the outer liner 300. The connecting frame 403 and the outer liner 300 are only in a telescopic movement relationship and cannot rotate relative to each other. An elastic element 407 is positioned at the midpoint of the inner edge of the locking component 406 and the outer ring cover 401. The outer ring cover 401 has a pre-reserved vertical channel 410 for the telescopic movement of the locking component 406. The specifications of the vertical channel 410 are compatible with those of the locking component 406. The vertical channel 410 and the elastic element 407 ensure that the locking component 406 will not rotate with the inner ring cover 405. The inner ring cover 405 has a pre-reserved curved channel 409 for bending... The overall outline of the channel 409 tends to change from the inner edge of the inner ring cover 405 to the outer periphery of the inner ring cover 405; a cylinder 408 is arranged on the side of the locking member 406, and the cylinder 408 is located in the curved channel 409; a fan-shaped channel 411 is reserved on the inner ring cover 405, and the size of the fan-shaped channel 411 is larger than the size of the locking member 406, so that when the inner ring cover 405 rotates, it will not drive the locking member 406 to rotate together.

[0034] This implementation will achieve the following: During assembly: Insert the monitor display cover 200 into the opening of the monitor outer cover 100. At this time, the slope of the triangular opening 203 on the connecting sleeve 202 and the slope of the locking piece 406 cooperate with each other, so that the locking piece 406 can retract into the outer ring cover 401 and the inner ring cover 405. After the final connection, the locking piece 406 corresponds to the final position of the triangular opening 203. At this time, under the action of the elastic element 407, the locking piece 406 and the triangular opening 203 are engaged. With the cooperation of the vertical edges, the position of the monitor display cover 200 is completely restricted, making the overall assembly easier. During maintenance: Rotate the outer liner 300. The inner ring cover 405 will move synchronously with the outer liner 300 through the connecting bracket 403. At this time, the correspondence between the curved channel 409 and the cylinder 408 changes. The cylinder 408 can drive the locking piece 406 to extend and retract towards the outer periphery of the inner ring cover 405. After the locking piece 406 leaves the triangular opening 203, the monitor display cover 200 can be easily removed. The overall operation is relatively easy and convenient. The outer liner 300 not only has a sealing effect but also a beautiful effect. Moreover, the operation position is not very conspicuous and is relatively hidden, making it less likely to be accidentally operated.

[0035] It should be understood that numerous specific implementation decisions can be made during the development of any actual implementation method, and in any engineering or design project. Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0036] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
