Description

Technical Field

[0001] This application relates to the technical field of smart grids, and in particular to a floor-mounted outdoor ring main unit. Background Technology

[0002] Currently, with the continuous advancement of urban power distribution network renovation projects, 10kV outdoor ground-mounted ring main units, as key branching and transfer equipment in urban power distribution networks, are being deployed in large numbers in busy urban areas such as commercial streets, residential markets, and sidewalks, undertaking core power supply functions such as regional power distribution, line segment protection, and fault isolation.

[0003] In related technologies, a 10kV small outdoor ring main unit includes a cabinet and two cabinet doors that are rotatably installed on the front side of the cabinet. The height and length of the cabinet are both about 1.2 meters, and several heat dissipation vents are opened on both the left and right sides of the cabinet. A grounding bolt is fixed at the lower edge of the front side of the cabinet. When installing and applying the ring main unit, the bottom surface of the cabinet is fixed to the top surface of the pre-laid cement base with bolts, and the grounding wire is connected to the grounding bolt.

[0004] When the aforementioned ring main unit is applied to a cement base near a busy urban area, the complex flow of people in the area means that passersby who are buying groceries, carrying packages, or shopping may stop to rest, unpack their packages, or organize their belongings. Since the unit is about 1.2 meters high, they may subconsciously place cardboard boxes, plastic bags, takeout food, and shopping bags directly on the top surface of the flat unit. However, the long-term placement of heavy objects may cause the top plate of the unit to deform, damage the unit's protective sealing, and shorten the equipment's lifespan, indicating room for improvement. Summary of the Invention

[0005] The purpose of this application is to provide a floor-standing outdoor ring main unit that solves the problem in the above-mentioned related technologies that passersby can easily pile up debris on the top of the unit, which can easily cause deformation of the top plate, damage to the seal of the unit, and shorten the service life of the equipment.

[0006] The technical solution for a floor-mounted outdoor ring main unit provided in this application is as follows: A floor-standing outdoor ring main unit includes a cabinet body and a cabinet door rotatably mounted on the front side of the cabinet body. Several ventilation openings are provided on the left and right sides of the cabinet body. Control components are provided on the inner wall of the cabinet body. Protective plates are rotatably mounted on the left and right edges of the top surface of the cabinet body. The two protective plates can rotate towards each other to a protective state where they abut against the top surface of the cabinet body, and can rotate away from each other to a receiving state where they are flush with the top surface of the cabinet body. When in the protective state, the outer edges of the top surfaces of the two protective plates are provided with downward-sloping guide slopes, and there is a clearance between the sides of the two protective plates when they are close to each other. The gap; a locking block is rotatably connected to the center of the front edge of the top surface of the cabinet. The locking block can rotate backward to a locked state that abuts against the top surface of the cabinet, and rotate forward to a positioned state that abuts against the front side of the cabinet. A positioning element is provided on the back side of the locking block when it is in the locked state; the locking block rotates to the locked state when the two protective plates are in the protective state, and the left and right sides of the locking block abut against the side wall of the clearance gap at this time; the locking block rotates to the positioned state when the two protective plates are in the receiving state, and the positioning element locks the state of the two protective plates at this time through the control element.

[0007] By adopting the above technical solution, a switchable protective plate and a linkage locking block are installed on the top surface of the cabinet, effectively solving the problem of cabinet top deformation and sealing failure caused by pedestrians randomly piling up debris in busy urban areas. When the protective plate is in the protective state, the inclined guide surface on the top surface can prevent the accumulation of objects on a flat surface, avoiding the accumulation of debris and heavy objects at the source, preventing the cabinet top plate from being deformed under pressure, and at the same time, it can quickly drain rainwater from the top surface, improving the waterproof performance of the cabinet top. The locking block is stored in the clearance gap and laterally abuts against the protective plate, realizing the stable positioning of the protective plate and ensuring the stability of the normal protective structure. When the equipment needs maintenance or when protection needs to be strengthened in rainy weather, the protective plate can be switched to the receiving state, and the state can be locked in conjunction with the locking block, positioning parts, and control parts. The flat surface of the protective plate can be temporarily placed for maintenance tools and parts, taking into account both equipment protection and on-site maintenance convenience, effectively extending the overall service life of the ring main unit, and adapting to complex outdoor urban application scenarios.

[0008] Optionally, the positioning element includes two positioning rods that are rotatably mounted side by side on the left and right sides of the locking block; when the locking block is in the locked state, the two positioning rods rotate towards each other to a side-by-side positioning state, and when the locking block is in the positioning state, they rotate away from each other to a coaxial control state; when the two positioning rods are in the positioning state, their left and right sides abut against the inner wall of the clearance gap, and their bottom surface abuts against the top surface of the cabinet.

[0009] By adopting the above technical solution, switchable positioning rods are set on both sides of the locking block to achieve precise adaptation and reinforced limiting between two working states. When the locking block is in the locked state, the two positioning rods are retracted towards each other, without occupying the clearance space, ensuring the normal protective function of the protective plate. When the locking block is switched to the positioning state, the positioning rods rotate back to front to a coaxial state. Through the dual limiting method of the outer wall abutting against the clearance and the bottom surface abutting against the top surface of the cabinet, the structural stability of the protective plate in the receiving state is greatly improved, preventing the protective plate from shaking or shifting under force. At the same time, the positioning rods can accurately cooperate with subsequent control components to complete the structural locking, realize mechanical linkage adaptation, and improve the linkage accuracy and reliability of the overall structure.

[0010] Optionally, when the two protective panels are in the receiving state, a storage groove is provided on the top surface, and a cover plate is rotatably connected to the upper edge of the inner wall of the two storage grooves that are close to each other at this time; when the two protective panels are in the receiving state, the two cover plates are rotated out from the storage groove to the unfolded state that abuts against the top surface of the cabinet, and when the two protective panels are in the protective state, they are rotated to the storage state located in the storage groove.

[0011] By adopting the above technical solution, when the protective panel is in its normal protective state, the cover is stored inside the storage trough, resulting in a flat and regular overall structure that does not interfere with the protective panel's functions of rain protection, drainage, and preventing the accumulation of items. When the protective panel is switched to the maintenance and acceptance state, the cover can be rotated out and unfolded to fit against the top surface of the cabinet, filling the gap on the top surface of the cabinet and forming a complete and flat storage surface, further expanding the maintenance and storage space. This structure can automatically adapt to the protective panel's state for storage and unfolding, requiring no manual disassembly or assembly. It has a high degree of structural integration, is easy to operate, and can also cover the gap at the top of the cabinet, further improving the cabinet's dustproof and waterproof effects.

[0012] Optionally, a control groove is provided at the opening edge of the receiving trough, and an arc-shaped protrusion is fixed on the outer side of the cover plate. The outer side of the arc-shaped protrusion is an arc surface with a minor arc length, and an arc-shaped groove is provided on the inner wall of the receiving trough. The arc-shaped protrusion is inserted into the arc-shaped groove when the cover plate is in the receiving state.

[0013] By adopting the above technical solution, the arc-shaped locking structure has guiding adaptability, and the cover plate can automatically align and snap into place when flipped for storage. The assembly is smooth and without jamming, requiring no additional locking components. The structure is simple and compact, requires no manual locking, and is not prone to failure during long-term outdoor use, significantly improving the overall structural stability and outdoor adaptability of the equipment.

[0014] Optionally, the top surface of the cabinet has a clearance hole for the upper end of the control rod to pass through, and the front side has a mounting hole. When the cover is in the unfolded state, the top surface has a locking hole that coincides with the clearance hole. The control components include a control rod that slides on the left and right side walls of the cabinet and has its upper end passing through the clearance hole; an elastic pressing component installed on the inner wall of the cabinet to drive the control rod to slide up and down; a traction rope with one end connected to the outer circumference of the lower end of the control rod; and a control block located on the front side of the cabinet. Two fixing blocks are fixed on the control block, and the front side of the cabinet has a... A fixed slot is provided. The other end of the traction rope passes through the mounting hole and is fixedly connected to the side of the control block facing the fixed slot. A positioning slot is provided on the end face of the positioning rod away from the locking block. When the two protective plates are in the protective state, the fixed slot is inserted into the fixed slot, and the top surface of the control rod is flush with the top surface of the cabinet. When the two protective plates are in the receiving state, the cover plate is in the unfolded state, and the two positioning rods are in the controlled state, the fixed slot is dislodged from the fixed slot, and the fixed slot is inserted into the positioning slot. The upper end of the control rod moves up and inserts into the locking hole.

[0015] By adopting the above technical solution, during normal operation, the fixing block engages with the fixing slot on the cabinet, locking the control structure and ensuring the protective plate remains stably in a protective state. During maintenance or in rainy conditions, the fixing block disengages from the fixing slot on the cabinet and engages with the positioning slot on the positioning rod. Pulling the traction rope moves the control rod upward and inserts it into the locking hole of the cover plate, simultaneously locking the working state of the cover plate, protective plate, and positioning rod. The purely mechanical linkage structure requires no electrical control components, resulting in a low failure rate, rapid response, and one-button switching and locking of operating conditions, significantly improving the ease of operation and stability of the equipment.

[0016] Optionally, an elastic sealing ring is embedded in the inner wall of the relief hole.

[0017] By adopting the above technical solution, an elastic sealing ring is embedded in the inner wall of the clearance hole, which can effectively seal the assembly gap between the control rod and the clearance hole, significantly improving the sealing, waterproofing, and dustproofing performance of the top of the cabinet. Under normal conditions, the sealing ring fits against the outer wall of the control rod, preventing outdoor rainwater, dust, and insects from entering the cabinet through the gap, thus protecting the electrical components inside the cabinet.

[0018] Optionally, a guide slope is provided on the outer edge of the side of the fixing block away from the control block.

[0019] By adopting the above technical solution, a guide slope is set on the outside of the fixed block to provide precise guidance for the locking and unlocking actions of the block, greatly reducing the operational difficulty of switching working conditions. Whether locking into the fixed slot on the cabinet or the positioning slot on the positioning rod, the guide slope can achieve automatic alignment and smooth engagement, eliminating the need for precise manual alignment, avoiding hard impacts and wear on the block, and extending the service life of the structure.

[0020] Optionally, the elastic compression member includes a protruding plate fixed on the outer periphery of the control rod and located inside the cabinet, and a compression spring located above the protruding plate and in a compressed state, with the two ends of the compression spring abutting against the top wall of the cabinet and the top surface of the protruding plate, respectively.

[0021] By adopting the above technical solution, during normal operation, the compression spring continuously applies pressure, pressing down the control rod through the protruding plate to make the top surface of the control rod flush with the top surface of the cabinet, ensuring the stability of the structure under normal conditions. When the working condition is changed and the traction rope is pulled, the spring force can be overcome to move the control rod upward, achieving structural locking; after the tension is released, the spring can automatically drive the control rod to reset, completing the structural reset. This elastic reset structure has a sensitive response and high stability. The purely mechanical structure is resistant to outdoor high and low temperatures and wind and rain erosion, and is not prone to failure, ensuring long-term stable cyclic operation of the control components.

[0022] Optionally, a sealing plate is slidably provided on the left and right side walls of the cabinet in the vertical direction. The top surface of the sealing plate is fixedly connected to the lower end surface of the control rod. The sealing plate has a sealing opening that can coincide with the heat dissipation vent. The sealing opening coincides with the heat dissipation vent when the upper end surface of the control rod is flush with the top surface of the cabinet, and is misaligned with the heat dissipation vent when the upper end of the control rod is inserted into the locking hole.

[0023] By adopting the above technical solution and utilizing the linkage design of the sealing plate and control lever, the adaptive switching of the heat dissipation vents is achieved, balancing heat dissipation and waterproofing requirements. During normal operation, the sealing opening and the heat dissipation vent coincide, ensuring normal airflow within the cabinet, achieving efficient heat dissipation, and guaranteeing stable operation of electrical equipment. In rainy weather or maintenance conditions, the control lever moves upward, simultaneously raising the sealing plate, causing the sealing opening and heat dissipation vent to misalign. The solid surface of the sealing plate completely blocks the heat dissipation vent, effectively preventing rainwater and dust from entering the cabinet. The structure automatically switches according to operating conditions, eliminating the need for manual sealing, resulting in a high degree of automation and precise adaptation to the usage needs of different environments.

[0024] Optionally, guide blocks located on the two vertical sides of the sealing plate are fixed on the left and right inner walls of the cabinet, and guide notches are provided on the guide blocks for the edge of the sealing plate to be inserted.

[0025] By adopting the above technical solution, the guide notch engages with the two sides of the sealing plate, which can limit the left and right displacement and back and forth swaying of the sealing plate, avoid problems such as misalignment, jamming, displacement and deformation caused by long-term sliding, and ensure that the sealing opening and heat dissipation opening are accurately aligned.

[0026] In summary, this application includes the following beneficial technical effects: In this application, a switchable protective panel and a linkage locking block are installed on the top surface of the cabinet, effectively solving the problem of cabinet top deformation and sealing failure caused by pedestrians randomly piling up debris in busy urban areas. When the protective panel is in the protective state, the inclined guide surface on the top surface can prevent the accumulation of objects on a flat surface, thus avoiding the accumulation of debris and heavy objects at the source, preventing the cabinet top panel from being deformed under pressure, and at the same time, it can quickly drain rainwater from the top surface, improving the waterproof performance of the cabinet top. By storing the locking block in the clearance gap and laterally abutting against the protective panel, the protective panel is stably limited, ensuring the stability of the normal protective structure.

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

[0030] Example: Reference Figure 1 and Figure 2 An outdoor ring main unit with a floor-standing design includes a cabinet body 1 and a cabinet door 2 rotatably mounted on the front side of the cabinet body 1. Several heat dissipation vents 11 are provided on the left and right sides of the cabinet body 1. A control component 6 is provided on the inner wall of the cabinet body 1. A protective component 3 is provided on the top surface of the cabinet body 1. The protective component 3 includes protective plates 31 rotatably mounted on the left and right edges of the cabinet body 1. The two protective plates 31 can rotate towards each other to a protective state that abuts against the top surface of the cabinet body 1, and rotate away from each other to a receiving state that is flush with the top surface of the cabinet body 1. When the two protective plates 31 are in the protective state, an inclined downward guide slope 311 is provided on the outer edge of the top surface of the two protective plates 31. There is a clearance between the sides of the two protective plates 31 that are close to each other at this time. A locking block 4 is rotatably connected to the center of the front edge of the top surface of the cabinet body 1. The locking block 4 can rotate backward to a locked state that abuts against the top surface of the cabinet body 1, and rotate forward to a positioning state that abuts against the front side of the cabinet body 1. When the locking block 4 is in the locked state, a positioning component 5 is provided on the back side. When the ring main unit is in normal use, the two protective plates 31 are pre-adjusted to the protective state, the locking block 4 is turned to the locked state, and the positioning piece 5 and the locking block 4 are both located in the clearance gap. At this time, the left and right sides of the locking block 4 abut against the side wall of the clearance gap, thereby limiting and fixing the two protective plates 31 in this state. During the later operation and maintenance of the ring main unit (or when it is raining and the protection of the heat dissipation port 11 needs to be strengthened), the two protective plates 31 are pre-adjusted to the receiving state, the locking block 4 is turned to the positioning state, and the positioning piece 5 locks the state of the two protective plates 31 at this time through the control piece 6. During operation and maintenance, additional operation and maintenance tools or parts can be temporarily placed on the top surface of the protective plate 31. During rainy weather protection, the protective plates 31 are used to protect the heat dissipation ports 11 on the left and right sides.

[0031] Reference Figure 1 and Figure 2 The positioning component 5 includes two positioning rods 51 that are rotatably mounted side by side on the left and right sides of the locking block 4. When the locking block 4 is in the locked state, the two positioning rods 51 rotate towards each other to a side-by-side positioning state, and when the locking block 4 is in the positioning state, they rotate away from each other to a coaxial control state. When the locking block 4 is in the positioning state, the two positioning rods 51 rotate in opposite directions to the coaxial control state. At this time, the left and right sides of the two positioning rods 51 abut against the inner wall of the clearance gap, and the bottom surface abuts against the top surface of the cabinet 1, so as to better limit and lock the state of the two protective plates 31 at this time.

[0032] Reference Figure 3When the two protective plates 31 are in the receiving state, a receiving groove 312 is provided on the top surface. At this time, a cover plate 32 is rotatably connected to the upper edge of the inner wall of the two receiving grooves 312 that are close to each other. An arc-shaped protrusion 321 is fixed on the outer side of the cover plate 32. The outer side of the arc-shaped protrusion 321 is an arc surface with a minor arc length. An arc-shaped groove 313 is provided on the inner wall of the receiving groove 312. A control groove 314 is provided at the opening edge of the receiving groove 312. When the two protective plates 31 are in the receiving state, the two cover plates 32 rotate out from the storage groove 312 to the unfolded state that abuts against the top surface of the cabinet 1; when the two protective plates 31 are in the protective state, the two cover plates 32 rotate to the storage state located in the storage groove 312, and the arc-shaped protrusion 321 is inserted into the arc-shaped groove 313, thereby improving the installation stability of the cover plates 32 in this state.

[0033] Reference Figure 4 , Figure 5 , Figure 6 and Figure 7 The cabinet 1 has a clearance hole 12 on its top surface for the upper end of the control rod 61 to pass through, and a mounting hole 13 on its front side. The inner wall of the clearance hole 12 is fitted with an elastic sealing ring 14 made of rubber. The cover plate 32 has a locking hole 322 on its top surface when it is in the unfolded state, which coincides with the clearance hole 12. The control component 6 includes a control rod 61 that slides on the left and right side walls of the cabinet 1 and passes through the clearance hole 12 at its upper end, an elastic pressing component 62 that is installed on the inner wall of the cabinet 1 to drive the control rod 61 to slide up and down, a traction rope 63 with one end connected to the outer peripheral surface of the lower end of the control rod 61, and a control block 64 located on the front side of the cabinet 1. The elastic compression member 62 includes a protruding plate 621 fixed on the outer periphery of the control rod 61 and located inside the cabinet 1, and a compression spring 622 located above the protruding plate 621 and in a compressed state. The two ends of the compression spring 622 abut against the top wall of the cabinet 1 and the top surface of the protruding plate 621, respectively. Two fixing blocks 65 are fixed on the control block 64. A guide slope 651 is provided on the outer edge of the side of the fixing block 65 away from the control block 64. A fixing slot 15 is opened on the front side of the cabinet 1. The other end of the traction rope 63 passes through the mounting hole 13 and is fixedly connected to the side of the control block 64 facing the fixing block 65. A positioning slot 511 is opened on the end face of the positioning rod 51 away from the locking block 4. When the two protective plates 31 are in the protective state (that is, when the ring main unit is in normal use), the fixing block 65 is inserted into the fixing slot 15, and the top surface of the control rod 61 is flush with the top surface of the cabinet 1. When the two protective plates 31 are in the receiving state, the cover plate 32 is in the unfolded state, and the two positioning rods 51 are in the control state (that is, when the ring main unit is under maintenance or when the protection is strengthened in rainy weather), the fixing block 65 is dislodged from the fixing slot 15, and the fixing block 65 is inserted into the positioning slot 511. The upper end of the control rod 61 moves up and is inserted into the locking hole 322.

[0034] Reference Figure 8 and Figure 9 A sealing plate 7 is slidably installed on the left and right side walls of the cabinet 1 along the vertical direction. The top surface of the sealing plate 7 is fixedly connected to the lower end face of the control rod 61. A sealing opening 71 that can coincide with the heat dissipation vent 11 is opened on the sealing plate 7. Guide blocks 16 located on the two vertical sides of the sealing plate 7 are fixed on the left and right inner walls of the cabinet 1. Guide notches 161 for the edge of the sealing plate 7 to be inserted are opened on the guide blocks 16. When the ring main unit is in normal use, the upper surface of the control rod 61 is flush with the top surface of the cabinet 1, and the sealing opening 71 coincides with the heat dissipation opening 11 to maintain normal heat dissipation performance. When the ring main unit is under maintenance or when protection is strengthened in rainy weather, the two protective plates 31 are in the receiving state, the upper end of the control rod 61 moves up and inserts into the locking hole 322, and the sealing opening 71 is misaligned with the heat dissipation opening 11 to prevent external rainwater from entering the cabinet 1 from the heat dissipation opening 11.

[0035] The implementation principle of this application embodiment is as follows: During normal operation, the two protective plates 31 are adjusted to the protective state, and the top guide slope 311 can guide rainwater, leaving space for assembly. The locking block 4 rotates to the locked state and is stored in the clearance, with its left and right side walls abutting against the protective plate 31, completing the limiting of the protective plate 31. At this time, the fixing block 65 of the control block 64 is engaged in the fixing slot 15 of the cabinet 1, restricting the movement of the traction rope 63. The control rod 61 keeps its top surface flush with the top surface of the cabinet 1, driving the sealing plate 7 to keep the sealing opening 71 aligned with the heat dissipation opening 11, ensuring normal ventilation and heat dissipation of the cabinet 1, and ensuring stable operation of the equipment; and the setting of the guide slope 311 prevents unauthorized personnel from placing debris on the top surface of the cabinet 1.

[0036] During maintenance or rain protection, the protective plate 31 is flipped to a receiving position flush with the top surface of the cabinet 1. The locking block 4 is rotated to the front positioning position, and the two positioning rods 51 rotate in opposite directions to a coaxial control position. At the same time, the locking of the fixing block 65 to the slot of the cabinet 1 is released, allowing the fixing block 65 to engage with the positioning slot 511 on the positioning rod 51. Pulling the traction rope 63 causes the control rod 61 to move upward against the spring force, and the upper end is inserted into the locking hole 322 on the cover plate 32, thus fixing the cover plate 32 and the protective plate 31 in this state. The control rod 61 simultaneously moves the sealing plate 7 upward, causing the sealing opening 71 to be misaligned with the heat dissipation opening 11. The heat dissipation opening 11 is sealed to prevent rainwater from seeping in, and the unfolded protective plate 31 can be temporarily placed to store maintenance tools and parts, taking into account both waterproof protection and maintenance convenience.

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.
