Description

Technical Field

[0001] This application relates to the technical field of ring network boxes, and in particular to an outdoor ring network box that is easy to clean from the top. Background Technology

[0002] In power supply and distribution systems, ring main units (RMS) play an irreplaceable role as key equipment. They rationally distribute electrical energy, effectively ensuring the stability and reliability of regional power supply. With the growth of electricity demand and the diversification of power consumption scenarios, small outdoor RMS units are widely used in urban streets, communities, industrial parks, and other outdoor locations due to their advantages such as small footprint and flexible installation. Their design must fully consider the complex outdoor environmental factors to ensure safe and stable operation under various conditions, providing solid support for the normal operation of the power system.

[0003] In related technologies, a small outdoor ring main unit includes a box body, a door installed on the vertical side of the box body, a top cover fixedly installed on the top surface of the box body, and several fixing protrusions fixedly installed on the lower part of the vertical outer side of the box body, with corresponding fixing through holes on the fixing protrusions. When using the outdoor ring main unit, a cement base higher than the ground is first laid at the installation site. The ring main unit is then hoisted onto the upper side of the cement base using hoisting equipment. Screws are then inserted through the fixing through holes on the fixing protrusions and screwed into the pre-drilled screw holes in the cement base, thereby achieving a stable installation of the ring main unit and ensuring its normal use in the outdoor environment.

[0004] However, when small outdoor ring cages are located in environments with high bird populations, some thorny problems arise. Due to frequent bird activity, their droppings easily adhere to the top cover of the cage. The top cover is constantly exposed to the outdoors, enduring wind, sun, and rain. If bird droppings are not cleaned for a long time, the acidic substances in the droppings will gradually corrode the surface of the top cover. Over time, this corrosion not only damages the appearance of the top cover, making it mottled and unsightly, but may also seriously affect the structural strength and waterproof performance of the top cover, thus shortening the overall lifespan of the ring cage. However, existing cleaning methods require ladders for climbing and specialized cleaning tools, making the process cumbersome and inefficient, and urgently need improvement. Summary of the Invention

[0005] The purpose of this application is to provide an outdoor ring cage that is easy to clean from the top, thereby solving the problem of low efficiency and cumbersome process of cleaning bird droppings adhering to the top cover in the aforementioned related technologies.

[0006] The outdoor ring network box provided in this application, which is easy to clean from the top, adopts the following technical solution:

[0007] An outdoor ring mesh box for easy top cleaning includes a box body, a top cover installed on the top of the box body, and a door rotatably installed on the vertical side of the box body. Ventilation vents are provided on two opposite vertical sides of the box body. A receiving groove is provided on the inner side of the door. Two support rods are arranged vertically side-by-side in the receiving groove, and several horizontal plates are arranged horizontally. The two ends of the horizontal plates are fixedly connected to the two support rods respectively. A connector rotatably connected to the upper end of each support rod is slidably mounted on the inner wall of the receiving groove. The connector can slide back and forth in the vertical direction. The rotation surface of the support rod is parallel to the vertical plane and perpendicular to the inner side of the door. The door is equipped with a control device to lock the sliding and rotation states of the support rods. When the door is opened to the point of contact with the surface of the ventilation vents, the locking of the support rods can be released by the control device. At this time, the support rods can slide downwards and rotate to a downward tilted position, and the horizontal plates are provided for workers to climb.

[0008] By adopting the above technical solution, when the top cover needs cleaning, the door is opened until it abuts against the surface of the heat dissipation vent. This releases the locking mechanism on the support rod, allowing it to slide downwards and rotate to a tilted downward position. At this point, the horizontal plate forms a structure that allows workers to climb, facilitating access to the top cover for cleaning and greatly improving cleaning efficiency. Furthermore, when not in use, the support rod and horizontal plate are stored in the recessed area on the inner side of the door, without taking up extra space or affecting the overall appearance and normal use of the ring main unit. Simultaneously, this simple and ingenious structure utilizes the door's own space and its rotating and sliding design to achieve convenient top cover cleaning, effectively solving the problems of low efficiency and cumbersome processes in existing cleaning methods, and extending the service life of the ring main unit.

[0009] Optionally, two guide blocks are fixedly provided on the inner wall of the receiving trough, and guide grooves are formed on the sides of the two guide blocks that are close to each other in the vertical direction; the connecting piece is a connecting block that is rotatably connected to the upper end of the support rod, and the side edges of the two connecting blocks that are far apart from each other are slidably installed in the guide groove.

[0010] By adopting the above technical solution, guide blocks and guide grooves are installed on the inner wall of the receiving trough. The connecting block, which is rotatably connected to the upper end of the support rod, is slidably installed within the groove. This provides precise guidance for the up-and-down sliding of the support rod, ensuring a smooth and stable sliding process without deviation or jamming, thus guaranteeing the stable operation of the structure. Simultaneously, this design also limits the connecting block, preventing it from detaching during sliding, enhancing the reliability and safety of the entire climbable structure, and providing greater protection for workers when using the horizontal planks to climb and clean the top cover.

[0011] Optionally, a limiting baffle is fixed on the side of the two support rods that are far apart from each other. The limiting baffle has a limiting slot on its bottom surface when the support rod is in a vertical state. The control component includes a control rod located on the outer side of the door and positioning rods vertically fixed at both ends of the control rod. A sealing plate is fixed on the outer periphery of the positioning rod. The door has a waist-shaped positioning hole in the vertical direction for the control rod to pass through and slide up and down. A positioning protrusion is fixed on the upper side of the end of the positioning rod away from the control rod. When the support rod is in a vertical state, the positioning protrusion can be inserted into the limiting slot, and one side of the sealing plate abuts against the outer side of the door at this time.

[0012] By adopting the above technical solution, when the support rod is in a vertical position, the positioning protrusion can be inserted into the limiting slot, and the sealing plate abuts against the outer side of the door, accurately and firmly locking the support rod to prevent it from shaking or rotating at will, thus ensuring structural stability. By sliding the control rod up and down within the waist-shaped positioning hole, the insertion and separation of the positioning protrusion and the limiting slot can be easily controlled, enabling flexible switching between the locked and unlocked states of the support rod. The operation is simple and convenient, providing a reliable guarantee for subsequent rotation and tilting of the support rod to allow workers to climb and clean the top cover.

[0013] Optionally, the door is provided with several air vents, and an upward-facing air guide shroud is fixed to the inner edge of the air vent opening; the horizontal plate is located above the air guide shroud when the support rod is in a vertical state; the horizontal plate can slide down to block the air guide shroud and slide up to release the air guide shroud from being blocked, and the control component can adjust and fix the support rod in both states.

[0014] By adopting the above technical solution, in the event of severe weather such as sandstorms or heavy rain, the sliding horizontal plate can effectively block external impurities and rainwater from entering the enclosure, preventing damage to internal electrical components and improving the stability and safety of equipment operation. In favorable outdoor conditions, the sliding horizontal plate releases its blockage, ensuring normal airflow through the air vents and the deflector, maintaining good heat dissipation performance of the enclosure, preventing overheating from affecting equipment performance and lifespan, thus balancing protection and heat dissipation requirements.

[0015] Optionally, control blocks are fixed on the two opposite vertical edges of the sealing plate, and several vertically distributed control slots are opened on the outer opening edge of the waist-shaped positioning hole; the control blocks are engaged in different control slots when the vertical height of the support rod is adjusted.

[0016] By adopting the above technical solution, the operation of the control block and the control slot is simple and convenient. When adjusting the height of the support rod, the operator only needs to make the control block fit into the corresponding slot, which improves the efficiency and convenience of operation and enhances the practicality and stability of the entire outdoor ring network box structure.

[0017] Optionally, a fixing plate is rotatably connected to the lower part of the vertical surface where the heat dissipation vent is located. A traction handle is detachably installed on the side of the fixing plate away from the box. Several fixing through holes are opened on the fixing plate. When the fixing plate is in a horizontal state, the bottom surface of the fixing plate is parallel to the bottom surface of the box. The traction handle can rotate upward with the fixing plate to a vertical state that is convenient for hoisting, and rotate downward to a horizontal state that is convenient for fixing.

[0018] By adopting the above technical solution, during hoisting, the traction handle rotates to a vertical position along with the fixing plate, facilitating connection to hoisting equipment and enabling convenient lifting. During installation and fixing, the fixing plate is rotated to a horizontal position, with its bottom surface parallel to the bottom surface of the box, allowing for stable installation on the base through the fixing through holes. Moreover, the traction handle is detachable, saving space. This design allows the ring main unit to flexibly switch between states during transportation and installation, meeting the needs of different scenarios and improving installation efficiency and ease of use.

[0019] Optionally, a limiting slot is provided on the upper side of the fixing plate when it is in a horizontal state; the lower end of the support rod can be inserted into the limiting slot when the horizontal plate is in a state for workers to climb.

[0020] By adopting the above technical solution, the limiting slots serve to position and limit the support rod, preventing it from swaying or shifting during use, thus enhancing the safety and stability for workers climbing. Simultaneously, this design cleverly utilizes the fixed plate structure, eliminating the need for additional complex components. While ensuring functionality, it makes the overall structure simpler and more rational, improving the practicality and reliability of the outdoor ring network box during operations such as cleaning the top cover.

[0021] Optionally, a middle rod is vertically fixed to the side of the traction handle facing the fixed plate, and a traction rod is vertically fixed to the end of the middle rod; the upper side of the fixed plate in a horizontal state has a receiving groove that communicates with the limiting groove and allows the middle rod to be inserted; the traction rod can be simultaneously inserted into the limiting groove when the middle rod is inserted into the receiving groove, and an elastic snap-fit ​​is provided on the outer periphery of the traction rod, and a first groove is provided on the inner wall of the limiting groove for the elastic snap-fit ​​to be inserted.

[0022] By adopting the above technical solution, when the fixed plate is horizontal, the intermediate rod is engaged in the receiving groove, the traction rod is engaged in the limiting groove, and the elastic snap-fit ​​component is engaged in the first groove, achieving multiple stable connections and enhancing the bonding strength between the traction handle and the fixed plate, making hoisting or fixing operations more reliable. At the same time, this design, while ensuring structural stability, facilitates flexible switching of the traction handle between hoisting and fixing states, and is convenient for disassembly and installation, improving the efficiency of outdoor ring network box transportation and installation, and providing convenience for the use of equipment in different scenarios.

[0023] Optionally, the two end faces of the control rod are rotatably connected to the sides of the two positioning rods that are close to each other. The control rod can rotate around its own axis, and a scraper is fixed on the outer periphery of the control rod along its own axis. When the control rod is installed on the door, the scraper is facing the door. When cleaning the top cover, the control rod can be removed from the door, and the scraper can then rotate to a position away from the positioning rods to clean the upper surface of the top cover.

[0024] By adopting the above technical solution, when cleaning the top cover is required, the control lever can be removed from the box door, and the scraper can be rotated away from the positioning lever to clean the upper surface of the top cover. This design eliminates the need for additional cleaning tools, utilizing the ring mesh box's own structure to achieve the top cover cleaning function, improving the convenience and efficiency of cleaning, effectively solving the problem of bird droppings and other stains corroding the top cover, and extending the service life of the ring mesh box.

[0025] Optionally, a second groove is provided on the side of the positioning protrusion and the sealing plate that are close to each other, so that the elastic snap-fit ​​can be inserted; the traction handle is detached from the fixing plate when the control rod is removed from the box door, and the traction rod can be inserted between the sealing plate and the positioning protrusion at this time, and the elastic snap-fit ​​can be inserted into the second groove at this time.

[0026] By adopting the above technical solution, after the control rod is removed and the traction handle is detached from the fixing plate, the traction rod can be engaged between the sealing plate and the positioning protrusion, and the elastic locking component can be engaged in the second groove. This design achieves a clever combination and stable connection between components. When cleaning the top cover, these components can be integrated into an auxiliary structure of a simple cleaning tool, enhancing the stability and convenience of the cleaning operation. At the same time, it makes full use of existing components without the need for additional complex devices, improving resource utilization and making the overall outdoor ring network box structure design more compact, reasonable, practical, and efficient.

[0027] In summary, this application includes the following beneficial technical effects:

[0028] When the top cover needs cleaning, open the door until it aligns with the surface of the ventilation vents. This releases the locking mechanism on the support rod, allowing it to slide downwards and rotate to a tilted downward position. At this point, the horizontal plate forms a structure that allows workers to climb, facilitating access to the top cover for cleaning and significantly improving efficiency. Furthermore, when not in use, the support rod and horizontal plate are stored in a recessed area on the inside of the door, without taking up extra space or affecting the overall appearance and normal operation of the ring main unit.

[0044] The present application will be further described in detail below with reference to all the accompanying drawings.

[0045] Example:

[0046] Reference Figure 1 and Figure 2 An outdoor ring mesh box that is easy to clean from the top includes a box body 1, a top cover 11 installed on the top of the box body 1, and a box door 2 rotatably installed on the vertical side of the box body 1. The other vertical edge of the box door 2 is detachably connected to the box door 2 by a conventional locking structure. Ventilation vents 12 are provided on two opposite vertical sides of the box body 1, and one of the box doors 2 can be rotated outward to abut against the vertical outer side where the ventilation vent 12 is located.

[0047] An auxiliary component 3 is provided on the inner side of the door 2 to assist workers in climbing to the upper side of the top cover 11. When it is necessary to clean the upper side of the top cover 11, the door 2 is opened to the state of contact with the vertical side where the heat dissipation vent 12 is located, and then the auxiliary component 3 is used to help workers quickly climb to the upper surface of the top cover 11 for cleaning.

[0048] Reference Figure 3 and Figure 4 The inner side of the door 2 is provided with a receiving groove 21. The auxiliary component 3 includes two support rods 31 arranged vertically side by side in the receiving groove 21 and several horizontal plates 32 arranged horizontally in the receiving groove 21. The two ends of the horizontal plates 32 are respectively fixedly connected to the two support rods 31.

[0049] The upper end of the support rod 31 is rotatably connected to a connector 33 that slides on the inner wall of the receiving trough 21. The connector 33 can slide back and forth in the up and down direction. The rotation surface of the support rod 31 is parallel to the vertical plane and perpendicular to the inner side of the box door 2. The box door 2 is provided with a control 4 that locks the sliding and rotation state of the support rod 31.

[0050] When the cabinet door 2 is opened to the point where it contacts the surface of the heat dissipation vent 12, the staff can release the lock on the support rod 31 through the control component 4, so that the support rod 31 can slide down and rotate to a tilted downward position. The horizontal plate 32 is then available for the staff to climb to clean the top cover 11.

[0051] Reference Figure 3 and Figure 4 The connecting piece 33 is a connecting block 331 that is rotatably connected to the upper end of the support rod 31. Two guide blocks 22 are fixedly provided on the inner wall of the sink 21. Guide grooves 221 are opened vertically on the sides of the two guide blocks 22 that are close to each other. When the connecting block 331 is installed, the side edges of the two connecting blocks 331 that are far apart from each other are slidably installed in the two guide grooves 221 respectively, thereby realizing the vertical sliding connection between the support rod 31 and the inner side of the box door 2, and the rotational connection along the vertical plane.

[0052] Reference Figure 4 and Figure 5 A limiting baffle 34 is fixed on the side of the two support rods 31 that are far apart from each other. The limiting baffle 34 has a limiting slot 341 on the bottom surface of the support rod 31 when it is in a vertical state. The control component 4 includes a control rod 41 located on the outer side of the door 2 and a positioning rod 42 fixed vertically at both ends of the control rod 41. A sealing plate 43 is fixed on the outer periphery of the positioning rod 42. A waist-shaped positioning hole 23 is opened on the door 2 along the vertical direction for the control rod 41 to pass through and slide up and down. A positioning protrusion 44 is fixed on the upper side of the end of the positioning rod 42 that is far away from the control rod 41.

[0053] When the support rod 31 is in a vertical position, the positioning rod 42 passes through the waist-shaped positioning hole 23. At this time, one side of the sealing plate 43 abuts against the outer side of the door 2, and the positioning protrusion 44 is located below the limiting baffle 34. Under the weight of the support rod 31 and the horizontal plate 32, the positioning protrusion 44 is inserted into the limiting slot 341, thereby limiting and locking the sliding and rotating states of the support rod 31. When cleaning the upper side of the top cover 11, the connecting piece 33 is removed from the door 2 to avoid interference and collision between the connecting piece 33 and the outer side of the box 1 where the heat dissipation vent 12 is located.

[0054] Reference Figure 6 and Figure 7 The door 2 is provided with several air vents 24, and an upward-facing air guide shroud 25 is fixed on the inner opening edge of the air vent 24; control blocks 431 are fixed on the two opposite vertical edges of the sealing plate 43, and two vertically distributed control slots 231 are provided on the outer opening edge of the waist-shaped positioning hole 23.

[0055] When the support rod 31 is in a vertical position, the horizontal plate 32 is located above the flow guide 25. The horizontal plate 32 can slide down to block the flow guide 25 and slide up to release the flow guide 25 from being blocked. The control block 431 can be inserted into different control slots 231 according to actual needs, so as to adjust and fix the support rod 31 in the blocked and open states of the flow guide 25.

[0056] Reference Figure 8 and Figure 9 The outer side of the housing 1 is provided with a traction assembly 5, wherein the traction assembly 5 includes a fixing plate 51 rotatably connected to the lower part of the vertical plane where the heat dissipation vent 12 is located, wherein a traction handle 52 is detachably installed on the side of the fixing plate 51 away from the housing 1; a plurality of fixing through holes 511 are provided on the fixing plate 51, and the bottom surface of the fixing plate 51 when it is in a horizontal state is parallel to the bottom surface of the housing 1.

[0057] When the ring network box is hoisted, the traction handle 52 is rotated upward with the fixing plate 51 to a vertical position. This makes it easier to fix the hoisting rope on the hoisting equipment to the traction handle 52 to hoist the ring network box. When the ring network box is fixed on the cement base, the traction handle 52 is rotated downward to a horizontal position. Then, the collision bolt passes through the fixing through hole 511 on the fixing plate 51 and is screwed into the pre-drilled screw hole on the cement base.

[0058] Reference Figure 10 A middle rod 53 is vertically fixed on the side of the traction handle 52 facing the fixed plate 51, and a traction rod 54 is vertically fixed at the end of the middle rod 53; a limiting groove 512 is opened on the upper side of the fixed plate 51 when it is in a horizontal state, and a receiving groove 513 is opened on the upper side of the fixed plate 51 when it is in a horizontal state, which communicates with the limiting groove 512 and allows the middle rod 53 to be inserted; an elastic snap-fit ​​member 55 is provided on the outer periphery of the traction rod 54, and a first groove 5121 is opened on the inner wall of the limiting groove 512;

[0059] The elastic snap-fit ​​component 55 includes a compression spring 551 and an arc-shaped protrusion 552. The traction rod 54 has a placement groove for the compression spring 551 and the arc-shaped protrusion 552 to be placed in. The compression spring 551 presses one side of the arc-shaped protrusion 552, causing a part of the arc-shaped protrusion 552 to protrude from the opening of the placement groove. The outer surface of the protruding part of the arc-shaped protrusion 552 is an arc surface, and the arc length corresponding to the arc surface is a minor arc.

[0060] When the intermediate rod 53 is inserted into the receiving groove 513, the traction rod 54 can be simultaneously inserted into the limiting groove 512. At this time, under the compression of the compression spring 551, the protruding part of the arc-shaped protrusion 552 is inserted into the corresponding first groove 5121, thereby improving the installation stability of the traction rod 54 in the limiting groove 512, and thus realizing the detachable connection between the fixing plate 51 and the traction handle 52.

[0061] Reference Figure 11 When the horizontal board 32 is in the position for workers to climb, the support rod 31 is tilted downwards. Workers can first remove the traction rod 54 from the limiting slot 512 so that the lower end of the support rod 31 can be inserted into the limiting slot 512, thereby fixing the tilted support rod 31.

[0062] Reference Figure 12 and Figure 13 The two ends of the control rod 41 are rotatably connected to the sides of the two positioning rods 42 that are close to each other. The control rod 41 can rotate around its own axis. A scraper 45 is fixed on the outer periphery of the control rod 41 along its own axis. The scraper 45 is facing the door 2 when the control rod 41 is installed on the door 2. The sides of the positioning protrusion 44 and the sealing plate 43 that are close to each other are provided with a second groove 441 for the elastic snap-fit ​​55 to be snapped into.

[0063] When cleaning the top cover 11, first remove the control lever 41 from the door 2, then rotate the scraper 45 away from the positioning lever 42, then remove the traction handle 52 from the fixing plate 51, and finally insert the traction rod 54 between the sealing plate 43 and the positioning protrusion 44, so that the elastic snap-fit ​​part 55 is inserted into the second groove 441. At this time, the control lever 41, scraper 45, positioning lever 42, traction handle 52, intermediate rod 53 and traction rod 54 together constitute a tool for cleaning the upper surface of the top cover 11. The worker holds the traction handle 52 and uses the scraper 45 to clean the upper surface of the top cover 11.

[0064] The implementation principle of this application embodiment is as follows:

[0065] During hoisting, the traction handle 52 is rotated upward with the fixing plate 51 to a vertical position, which facilitates the fixing of the hoisting rope on the hoisting equipment to the traction handle 52, thereby realizing the hoisting of the ring network box; during installation, the traction handle 52 is kept in a horizontal position with the fixing plate 51, and the fixing plate 51 is fixed to the cement base with bolts.

[0066] In normal use, the door 2 is closed, the auxiliary component 3 is stored in the receiving trough 21, and the support rod 31 is locked by the control component 4 and is in a vertical position. In addition, the control block 431 can be adjusted to be inserted into different control slots 231 according to the actual outdoor environment, and the control plate 32 can be used to block or open the guide shroud 25.

[0067] When it is necessary to climb and clean the top cover 11, open the box door 2 until it abuts against the vertical outer side where the heat dissipation vent 12 is located, release the locking of the control component 4 on the support rod 31, so that the support rod 31 slides down and rotates to the inclined downward state, and the lower end of the support rod 31 is locked into the limiting slot 512 of the fixing plate 51. At this time, the horizontal plate 32 can be used by the staff to climb to the top cover 11 for cleaning.

[0068] When using the control lever 41 and the traction handle 52 to form a cleaning tool, first remove the control lever 41 from the box door 2, rotate the scraper 45 to a position away from the positioning rod 42, then disassemble the traction handle 52, insert the traction rod 54 between the sealing plate 43 and the positioning protrusion 44, so that the elastic snap-fit ​​55 is inserted into the second groove 441. At this time, the control lever 41, scraper 45, positioning rod 42, traction handle 52, intermediate rod 53 and traction rod 54 constitute the cleaning tool. The worker holds the traction handle 52 and uses the scraper 45 to clean the upper surface of the top cover 11.
