Description

Technical Field

[0001] This application relates to the technical field of smart grids, and in particular to a primary and secondary integrated ring network box that is easy to maintain in the later stages. Background Technology

[0002] As smart grid construction deepens towards distribution automation and compactness, integrated primary and secondary ring main units (RMUs) are becoming increasingly important as key node equipment in urban distribution networks, with their integration level and outdoor adaptability receiving increasing attention. Especially in scenic areas such as urban parks and greenbelts, RMUs not only undertake the core functions of power distribution and fault isolation but also need to consider environmental aesthetics and long-term maintenance-free operation. Because these devices are typically installed near vegetation, they are significantly affected by the surrounding ecological environment, posing new challenges to traditional operation and maintenance models. Therefore, improving the self-cleaning capability and ease of operation and maintenance of equipment in complex natural environments while ensuring stable electrical performance has become an important research direction for the current intelligent upgrading of distribution networks.

[0003] A typical primary and secondary integrated ring main unit structure is disclosed in related technologies. This equipment includes a housing, several doors hinged to the front and rear sides of the housing, and a cover fixedly installed on the top surface of the housing. The top edge and rear edge of the cover are integrally formed or fixedly connected with downward-sloping guide ramps, which guide rainwater to slide off quickly under gravity, aiming to achieve rain and water protection. In addition, several strip-shaped heat dissipation vents are provided on the left and right sides of the housing, utilizing the principle of natural air convection heat transfer to dissipate heat from the internal high-voltage switchgear and control unit. During construction and installation, the ring main unit is typically hoisted as a whole to a pre-set concrete base using hoisting equipment, and then the bottom of the housing is firmly fixed using anchor bolts or expansion bolts.

[0004] When used in tree-covered environments such as parks, fallen leaves and branches often accumulate on the top of the enclosure lid. Because these accumulated leaves remain damp during the rainy season or in high-humidity conditions, this dampness accelerates corrosion of the lid surface, necessitating regular cleaning. However, the standard installation height of these ring main units is typically around two meters, making it difficult to detect leaf accumulation during routine inspections. When cleaning is required, maintenance personnel must climb using ladders, frequently moving the ladders and adjusting their posture to cover the entire lid surface. This process is not only time-consuming and labor-intensive, but also poses safety hazards such as falls from heights and contact with live parts, indicating room for improvement. Summary of the Invention

[0005] The purpose of this application is to provide a primary and secondary integrated ring network box that is easy to maintain in the later stage, and to solve the problems of difficult cleaning of fallen leaves on the top surface of the box cover, high labor intensity and safety hazards caused by the need for high-altitude operations in the above-mentioned related technologies.

[0006] This application provides a primary and secondary integrated ring main unit that facilitates later maintenance, employing the following technical solution: A primary and secondary fusion ring network box that is easy to maintain includes a box body, several boxes doors rotatably installed on the front and rear sides of the box body, and a box cover installed on the top surface of the box body. The front and rear edges of the top surface of the box cover are provided with guide slopes. A scraper with its length direction perpendicular to the front side of the box body is slidably installed on the top surface of the box cover, and the bottom surface of the scraper abuts against the guide slopes. The upper part of the left and right sides of the box body is provided with winding wheels and a drive component that drives the winding wheels to rotate is fixedly installed. The upper part of the box cover is provided with a traction rope at both ends that are fixedly connected to the outer circumference of the two winding wheels respectively. The scraper is provided with clearance holes for the traction rope to pass through and be fixed. When one of the two winding wheels is winding, the other is unwinding, which drives the scraper to slide back and forth.

[0007] By adopting the above technical solution, a scraper is installed on the top surface of the box cover, which abuts against the guide slope. The scraper is driven by the upper winding wheels on the left and right sides of the box, a drive mechanism, and a traction rope, allowing maintenance personnel to clean the leaves and debris accumulated on the top of the box cover without needing to climb to the two-meter-high top of the box using a ladder. The drive mechanism drives one of the two winding wheels to wind up while the other winds down. The traction rope pulls the scraper along the top surface of the box cover through the clearance hole. The scraper's bottom surface scrapes away the dead leaves and branches accumulated on the guide slope to one side, replacing the traditional high-altitude operation method of manually sweeping with hand tools section by section. This structure effectively solves the problems of difficulty in detecting leaf accumulation on the top during daily inspections due to the high installation height of the ring network box, the high labor intensity caused by frequent ladder movements and body adjustments during cleaning, and the risk of falls from height. It achieves the technical effect of quickly removing accumulated materials on the top of the box cover from the ground, significantly improving the convenience and safety of later maintenance, while avoiding the accelerated corrosion of the box cover surface caused by long-term coverage of damp leaves.

[0008] Optionally, a dovetail slide rail is fixed in the middle of the top surface of the box cover in the horizontal direction. The length direction of the dovetail slide rail is parallel to the front side of the box door, and a dovetail notch is opened on the bottom surface of the scraper to slide with the dovetail slide rail.

[0009] By adopting the above technical solution, the length direction of the dovetail slide rail is parallel to the front side of the box door. The trapezoidal cross-section structure of the dovetail slide rail restricts the vertical displacement of the scraper, preventing the scraper from tilting or shifting due to external force during sliding. This ensures that the bottom surface of the scraper is always in close contact with the guide slope, thereby ensuring that the scraper can scrape the fallen leaves on the top surface of the box cover evenly and thoroughly. At the same time, it reduces the frictional resistance between the scraper and the top surface of the box cover, extending the service life of the scraper and the box cover.

[0010] Optionally, tensioning wheels are rotatably mounted on both the left and right sides of the box cover, and tensioning ring grooves for inserting traction ropes are formed on the outer circumference of the tensioning wheels.

[0011] By adopting the above technical solution, tensioning wheels with tensioning ring grooves are rotatably installed on the left and right sides of the box cover, and the traction rope is placed into the tensioning ring groove, so that the traction rope always maintains a suitable tension between the winding wheel and the scraper.

[0012] Optionally, vertically upward support rods are fixed on the front and rear sides of the box cover, and a crossbeam is fixed above the box cover with both ends fixedly connected to the upper end face of the support rods. Extension rods are coaxially fixed on both ends of the crossbeams, and a monitoring camera is fixed on the bottom surface of the end of the extension rod away from the crossbeam. When the scraper slides back and forth, it is located below the crossbeam.

[0013] By adopting the above technical solution, support rods are fixed on the front and rear sides of the enclosure cover, and a crossbeam is fixed on the upper end of the support rod. Extension rods are coaxially fixed on both ends of the crossbeam, and a monitoring camera is fixed on the bottom surface of the extension rods away from the crossbeam. This allows the monitoring camera to be stably supported above the enclosure cover and to obtain a monitoring view around the ring network enclosure. The scraper remains below the crossbeam during its reciprocating slide. This layout ensures that the sliding trajectory of the scraper and the installation position of the monitoring camera do not interfere with each other spatially. This achieves automatic cleaning of the top surface of the enclosure cover and utilizes the top space of the enclosure to integrate the video monitoring equipment, improving the security monitoring capability of the ring network enclosure in outdoor scenarios without obstructing the normal sliding of the scraper.

[0014] Optionally, a protective cover is slidably mounted below the two extension rods, located between the monitoring camera and the support rod. The protective cover has an opening on its side away from the support rod, and a positioning rod is fixed on its side facing the support rod. The support rod has a support hole through which the positioning rod passes and slides. A control rod is fixed vertically on the end face of the positioning rod away from the protective cover. A guide groove is provided on the crossbeam for the upper end of the control rod to pass through and slide. An elastic abutment rod with a length perpendicular to the front side of the housing and elastic elongation properties is fixed on the bottom surface of the crossbeam. Both ends of the abutment rod abut against the outer peripheral surfaces of the lower ends of the two control rods, respectively; adjustment blocks are fixed at the front and rear edges of the top surface of the scraper, and guide slopes are provided at the left and right edges of the sides of the two adjustment blocks that are close to each other; when the scraper slides to below the crossbeam, the guide slopes on the adjustment blocks abut against the opposite sides of the two control rods, and the sides of the two protective covers that are close to each other abut against the opposite sides of the two support rods; when the scraper slides to a state of misalignment with the crossbeam, the elastic abutment rod drives the two control rods to slide in opposite directions, and the protective cover slides to a position below the monitoring camera.

[0015] By adopting the above technical solution, a protective cover is slidably installed below the extension rod, a positioning rod is fitted with a support hole, a control rod is fitted with a guide groove, and an elastic abutment rod is fixed on the bottom surface of the crossbeam. Combined with the adjusting block and guide slope on the top surface of the scraper, this achieves automatic linkage between the scraper's position change and the opening and closing state of the protective cover. When the scraper slides below the crossbeam, the guide slope on the adjusting block abuts against the opposite sides of the two control rods, pushing the protective cover closer together and misaligning it with the monitoring camera, allowing the monitoring camera to monitor normally without obstruction. When the scraper slides to a state of misalignment with the crossbeam, the elastic abutment rod drives the two control rods to slide back and forth, and the protective cover slides below the monitoring camera, providing physical shielding for the monitoring camera during cleaning operations and reducing the possibility of external impurities adhering to the outer surface of the monitoring camera.

[0016] Optionally, control slots are provided on the outer periphery of the two control rods that are close to each other at their lower ends, allowing the ends of the elastic abutment rods to be engaged.

[0017] By adopting the above technical solution, the control slot provides a stable locking position for the end of the elastic abutment rod, preventing the elastic abutment rod from shifting laterally or falling off under long-term expansion and contraction deformation or vibration environment. This ensures that the elastic abutment rod can always reliably apply elastic thrust in opposite directions to the two control rods, thereby ensuring that the protective cover can be stably maintained in the protective position below the monitoring camera when the scraper slides to a state of misalignment with the crossbeam, thus improving the operational stability of the entire linkage protection mechanism.

[0018] Optionally, locking blocks are fixed on the sides of the two protective covers that are far apart from each other, and locking slots are opened on the sides of the two support rods that are opposite to each other. The locking blocks are inserted into the locking slots when the scraper slides to the bottom of the crossbeam.

[0019] By adopting the above technical solution, additional locking and positioning is provided for the protective cover when it is misaligned with the monitoring camera, preventing the protective cover from sliding unexpectedly under wind or other external disturbances, ensuring that the monitoring camera is always unobstructed during daily operation. At the same time, the plugging and mating of the locking block also enhances the connection rigidity between the protective cover and the support rod, keeping the protective cover stable under normal conditions and avoiding abnormal noise or positional displacement caused by vibration.

[0020] Optionally, a guide slope is provided on the outer edge of the side of the locking block away from the protective cover.

[0021] By adopting the above technical solution, a guide slope is set on the outer edge of the side of the locking block away from the protective cover, so that the locking block can be smoothly guided and directed during the process of being inserted into the locking slot.

[0022] Optionally, a protective plate is fixed horizontally above the crossbeam, and a vertically upward-facing barrier plate is fixed on the top surface of the two extension rods at their far-away ends. A horizontally arranged bent plate is fixed on the top surface of the two barrier plates in a far-away direction, and an installation hole is opened on the top surface of the bent plate. A sealing plate that can slide up and down is slidably mounted on the vertically slidable sides of the two barrier plates. A connecting rope is provided above the crossbeam, with its two ends fixedly connected to the top surface of the sealing plate and the upper end surface of the control rod, respectively, and passing through the installation hole. When the scraper and the crossbeam are misaligned, the sealing plate moves down to seal the receiving opening on the protective cover. When the scraper slides to the bottom of the crossbeam, the top surface of the sealing plate abuts against the bottom surface of the bent plate.

[0023] By adopting the above technical solution, a protective plate is installed above the crossbeam, and a blocking plate and a bending plate are installed at the end of the extension rod. The sealing plate is connected to the control rod by a connecting rope, realizing the synchronous lifting and lowering of the sealing plate with the movement of the control rod. When the scraper is misaligned with the crossbeam, the sealing plate moves down to seal the receiving opening on the protective cover, forming a closed protection for the monitoring camera together with the protective cover, further preventing dust or scattered debris generated during the cleaning process from entering the surface of the monitoring camera. When the scraper slides to the bottom of the crossbeam, the top surface of the sealing plate abuts against the bottom surface of the bending plate, removing the obstruction to the monitoring camera and restoring the monitoring camera to its normal monitoring field of view. This structure achieves automatic switching of multiple protections without adding an additional drive source.

[0024] Optionally, a limiting rod is fixed on the top surface of the sealing plate, and a limiting hole is opened on the top surface of the bent plate for the limiting rod to pass through; the upper end of the limiting rod abuts against the bottom surface of the protective plate when the scraper slides to below the crossbeam.

[0025] By adopting the above technical solution, the cooperation between the limiting rod and the limiting hole restricts the horizontal swing and deflection of the sealing plate, ensuring that the sealing plate can accurately align with the receiving opening on the protective cover to complete the sealing action. At the same time, when the scraper slides to below the crossbeam, the upper end face of the limiting rod abuts against the bottom surface of the protective plate, providing a rigid limit to the upper limit position of the sealing plate, preventing the sealing plate from moving too high and causing the connecting rope to loosen or come off, thus ensuring the stable storage position of the sealing plate when the monitoring camera is working normally.

[0026] In summary, this application includes the following beneficial technical effects: In this application, the drive unit drives one of the two winding wheels to wind up while the other winds up. The traction rope pulls the scraper along the top surface of the box cover through the clearance hole. The bottom surface of the scraper scrapes away the dead branches and leaves accumulated on the guide slope to one side, replacing the traditional high-altitude operation method of manually sweeping with hand tools section by section, which greatly improves the convenience and safety of later maintenance.

[0029] The present application will be further described in detail below with reference to all the accompanying drawings.

[0030] Example: Reference Figure 1 , Figure 2 and Figure 3A primary and secondary fusion ring network box that is easy to maintain in the later stage includes a box body 1, a number of box doors 11 rotatably installed on the front and rear sides of the box body 1, and a box cover 12 installed on the top surface of the box body 1. The front and rear edges of the top surface of the box cover 12 are provided with guide slopes 121. A cleaning component 2 is provided on the top surface of the box cover 12, wherein the cleaning component 2 includes a scraper 21 slidably installed on the top surface of the box cover 12 and perpendicular to the front side of the box body 1 in the length direction. The bottom surface of the scraper 21 abuts against the guide slope 121. The upper part of the left and right sides of the housing 1 is provided with a winding wheel 22 and a drive component 23 that drives the winding wheel 22 to rotate. The drive component 23 is a servo motor that can rotate forward and reverse. The upper part of the housing cover 12 is provided with a traction rope 24 at both ends, which is fixedly connected to the outer circumference of the two winding wheels 22 respectively. The scraper 21 is provided with a clearance hole for the traction rope 24 to pass through and be fixed. When cleaning the top surface of the cover 12, the two drive units 23 are activated. When one of the two winding wheels 22 is winding, the other is unwinding, thereby driving the scraper 21 to slide back and forth, and then using the scraper 21 to clean the top surface of the cover 12. When the ring network box is in normal use, the scraper 21 is slid to the middle of the top surface of the cover 12 and remains unchanged.

[0031] Reference Figure 2 and Figure 3 A dovetail slide rail 13 is fixedly installed in the middle of the top surface of the box cover 12 in the horizontal direction. The length direction of the dovetail slide rail 13 is parallel to the front side of the box door 11, and a dovetail notch 211 is opened on the bottom surface of the scraper 21 to slide with the dovetail slide rail 13. Tensioning wheels 14 are rotatably installed on the left and right sides of the box cover 12, and tensioning ring grooves for inserting traction ropes 24 are opened on the outer periphery of the tensioning wheels 14.

[0032] Reference Figure 3 and Figure 4 The outer side of the box cover 12 is provided with a support assembly 3, wherein the support assembly 3 includes a support rod 31 fixed vertically on the front and rear sides of the box cover 12. A crossbeam 32 is fixedly provided above the box cover 12, with both ends fixedly connected to the upper end face of the support rod 31. An extension rod 33 is coaxially fixed on both ends of the crossbeam 32. A monitoring camera 4 is fixed on the bottom surface of the end of the extension rod 33 away from the crossbeam 32. The monitoring camera 4 is a conventional monitoring device, which will not be described in detail here. The monitoring camera 4 is supported and fixed by the crossbeam 32 and the two support rods 31, and slides with the scraper 21, that is, the scraper 21 always slides below the crossbeam 32.

[0033] Reference Figure 5 , Figure 6 and Figure 7Below the two extension rods 33, a protective component 5 is provided. The protective component 5 includes a protective cover 51 that slides on the bottom surface of the two extension rods 33 and is located between the monitoring camera 4 and the support rod 31. The protective cover 51 has an accommodating opening 511 on the side away from the support rod 31 and a positioning rod 52 fixed on the side facing the support rod 31. The support rod 31 has a support hole 311 for the positioning rod 52 to pass through and slide. A control rod 53 is fixed in the vertical direction on the end face of the positioning rod 52 away from the protective cover 51. The crossbeam 32 has a guide groove 321 for the upper end of the control rod 53 to pass through and slide. An elastic abutment rod 54 with a length perpendicular to the front side of the box 1 and elastic elongation performance is fixed on the bottom surface of the crossbeam 32. The two ends of the elastic abutment rod 54 abut against the outer peripheral surfaces of the lower ends of the two control rods 53 respectively. The middle part of the top surface of the elastic abutment rod 54 is fixedly connected to the bottom surface of the crossbeam 32. The elastic abutment rod 54 is a conventional telescopic structure with an internal spring, which will not be described in detail here. Adjustment blocks 25 are fixed on the front and rear edges of the top surface of the scraper 21. Guide slopes 251 are provided on the left and right edges of the sides of the two adjustment blocks 25 that are close to each other. When the scraper 21 slides to below the crossbeam 32 (that is, when the ring network box is in normal use), the guide slope 251 on the adjusting block 25 abuts against the opposite sides of the two control rods 53, and the sides of the two protective covers 51 that are close to each other abut against the opposite sides of the two support rods 31. At this time, the protective cover 51 is misaligned with the monitoring camera 4. When the scraper 21 slides to the state of being misaligned with the crossbeam 32 (that is, when cleaning the top surface of the box cover 12), the elastic abutment rod 54 drives the two control rods 53 to slide in opposite directions. At this time, the protective cover 51 slides to the position below the monitoring camera 4, thereby reducing the possibility of external impurities adhering to the outer surface of the monitoring camera 4 during cleaning.

[0034] Reference Figure 5 , Figure 6 and Figure 7 The lower ends of the two control rods 53 are close to each other and have control slots 531 for the end of the elastic abutment rod 54 to be inserted into. The two protective covers 51 are fixed with locking blocks 55 on their opposite sides and have guide slopes 551 on the outer edge of the side of the locking blocks 55 away from the protective covers 51. The two support rods 31 are backed by locking slots 312. When the scraper 21 slides to the bottom of the crossbeam 32, the locking blocks 55 slide synchronously with the protective covers 51 and are inserted into the locking slots 312.

[0035] Reference Figure 7 , Figure 8 and Figure 9A protective plate 34 is fixed horizontally above the crossbeam 32. A vertically upward-facing barrier plate 35 is fixed on the top surface of the two extension rods 33 at their far-away ends. A horizontally arranged bent plate 36 is fixed on the top surface of the two barrier plates 35 in a far-away direction. An installation hole 361 is opened on the top surface of the bent plate 36. A sliding sealing plate 37 is slidably mounted vertically on the side surfaces of the two barrier plates 35 in a far-away direction. A limiting rod 371 is fixed on the top surface of the sealing plate 37. A limiting hole 362 for the limiting rod 371 to pass through is opened on the top surface of the bent plate 36. A connecting rope 38 is provided above the crossbeam 32, with both ends fixedly connected to the top surface of the sealing plate 37 and the upper end surface of the control rod 53, respectively, and passing through the installation hole 361. When the scraper 21 is misaligned with the crossbeam 32 (that is, when cleaning the top surface of the box cover 12), the sealing plate 37 moves down to seal the receiving opening 511 on the protective cover 51, using the protective cover 51 and the sealing plate 37 to provide external protection for the monitoring camera 4; when the scraper 21 slides to the bottom of the crossbeam 32 (that is, when the ring network box is in normal use), the top surface of the sealing plate 37 abuts against the bottom surface of the bending plate 36, the bottom surface of the sealing plate 37 is flush with the bottom surface of the crossbeam 32, and the upper end surface of the limit rod 371 abuts against the bottom surface of the protective plate 34, at which time the monitoring camera 4 is operating normally.

[0036] The implementation principle of this application embodiment is as follows: When the ring main unit is in normal operation, the scraper 21 slides to directly below the crossbeam 32. At this time, the guide slope 251 on the adjusting block 25 abuts against the opposite sides of the two control rods 53, pushing the two control rods 53 to slide towards each other. The two protective covers 51 move closer to each other under the action of the positioning rod 52 until the sides of the protective covers 51 that are close to each other abut against the opposite sides of the two support rods 31. At this time, the protective covers 51 are misaligned with the monitoring camera 4. At the same time, the locking block 55 slides synchronously with the protective cover 51 and inserts into the locking slot 312 on the support rod 31. The sealing plate 37 is moved upward by the connecting rope 38, so that the top surface of the sealing plate 37 abuts against the bottom surface of the bent plate 36, the bottom surface is flush with the bottom surface of the crossbeam 32, and the upper end surface of the limiting rod 371 abuts against the bottom surface of the protective plate 34. The monitoring camera 4 is unobstructed and operates normally.

[0037] When cleaning the top surface of the cover 12, the drive unit 23 is activated, one of the two winding wheels 22 winds up while the other unwinds. The traction rope 24, guided by the tensioning ring groove of the tensioning wheel 14, drives the scraper 21 to slide back and forth along the dovetail slide rail 13. When the scraper 21 slides to the point of misalignment with the crossbeam 32, the guide slope 251 on the adjusting block 25 disengages from the control rod 53, and the elastic abutment rod 54 releases its elastic force to push the two control rods 53 to slide in opposite directions. The control rod 53, through the positioning rod 52, drives the protective cover 51 to slide below the monitoring camera 4, and the locking block 55 disengages from the locking slot 312. At the same time, the sealing plate 37 slides down along the barrier plate 35 under its own weight, and the limiting rod 371 slides within the limiting hole 362 until the sealing plate 37 moves down and seals the receiving opening 511 on the protective cover 51, thus forming a closed protection for the monitoring camera 4 together with the protective cover 51. (Although it will pass directly under the crossbeam 32 during the sliding process, it will only be for a very short time, and only at this time will the protection of the surveillance camera 4 be removed. However, the surveillance camera 4 will be in the protected state for most of the time during the cleaning process.) The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be included within the scope of protection of this application.
