Description

Technical Field

[0001] This application relates to the technical field of ring main units, and in particular to a shockproof ring main unit. Background Technology

[0002] In power systems, ring main units are crucial electrical devices, undertaking the key task of relaying and connecting power distribution networks. They act like "transportation hubs" in the power transmission network, ensuring a stable supply and rational distribution of electricity. With rapid urbanization, expanding urban areas, and increasingly frequent infrastructure construction and industrial and commercial activities, electricity demand is showing a continuous upward trend. At the same time, the application scenarios for ring main units are becoming more widespread, and their working environments are becoming increasingly complex and diverse, ranging from relatively stable areas to various harsh environments. This places higher demands on the performance and reliability of ring main units.

[0003] Currently, outdoor ring main units have seen some technological advancements. A typical outdoor ring main unit mainly consists of a box body and a door mounted on the box body. The box body has specially designed wiring holes for external cables to pass through. In practical applications, after the corresponding electrical cabinet is installed inside the box, external cables can be easily connected to the box through these wiring holes, achieving a reliable connection with the electrical cabinet and thus completing the functions of power transmission and distribution. This design, to a certain extent, meets basic power usage needs and provides a fundamental guarantee for the normal operation of the power system.

[0004] However, when outdoor ring main units are applied in specific environments, existing technologies reveal significant shortcomings. For example, in outdoor settings where vibrations are frequent, such as roadsides where large vehicles pass by, the ring main units will shake with these vibrations. In this situation, the external cables will frequently come into contact with and rub against the inner walls of the connection holes. Prolonged exposure to this condition can easily damage the insulation layer and other parts of the external cables, leading to breakage. Once the cables are damaged, it will not only affect the normal transmission of electricity but may also cause safety accidents such as electrical leakage, posing a serious threat to the safety of surrounding personnel and equipment, indicating significant room for improvement. Summary of the Invention

[0005] The purpose of this application is to provide a shockproof ring main unit to solve the problem in the above-mentioned related technologies that when the ring main unit is used in a frequently vibrating environment, the insulation of the external cable close to the inner wall of the wiring hole may be damaged, posing a safety hazard.

[0006] The anti-vibration ring network box provided in this application adopts the following technical solution:

[0007] An anti-vibration ring mesh box includes a box body. An installation cavity is formed on the front vertical surface of the box body, and a door is detachably installed to seal the opening of the installation cavity. Wiring ports communicating with the installation cavity are formed on the left and right sides of the box body. A fixed seat is fixedly mounted on the inner wall of the box body below the wiring ports. A sealing seat is rotatably connected to the upper edge of the fixed seat away from the door. A control rod is fixedly mounted on the side of the sealing seat facing the door. An elastic pressing member is provided on the inner wall of the box body, and the elastic pressing member drives the control rod to rotate towards the fixed seat. A sealing notch is formed on the side of the fixed seat and the sealing seat that are close to each other. An elastic pad is fixedly mounted on the inner wall of the sealing notch. When the fixed seat and the sealing seat abut against each other, the two sealing notches together form a sealing cavity that coincides with the wiring ports.

[0008] By adopting the above technical solution, under frequent vibration, when the external cable is connected to the inside of the enclosure through the connector, the elastic compression component functions, driving the control rod to rotate towards the fixed seat, causing the fixed seat and the sealing seat to abut against each other. At this time, the two sealing notches together form a sealed cavity that coincides with the connector, and the elastic pad on the inner wall of the sealing notch can tightly press against the outer circumference of the external cable. This design effectively avoids frequent contact and friction between the external cable and the inner wall of the connector during vibration, greatly reducing the possibility of damage or breakage of the insulation layer and other parts of the external cable due to long-term friction.

[0009] Optionally, the elastic compression member includes a first spring in a compressed state and a limiting plate fixed above the control rod, wherein the two ends of the first spring are fixedly connected to the limiting plate and the side of the control rod that are close to each other.

[0010] By adopting the above technical solution, the first spring, under compression, generates a stable and continuous elastic force through its own elastic potential energy. This force is precisely transmitted to the control rod through its two ends, which are fixedly connected to the sides of the limiting plate and the control rod respectively, causing the control rod to rotate stably towards the fixed seat. This ensures reliable contact between the sealing seat and the fixed seat, thereby tightly encasing the external cable in the sealing cavity. The limiting plate not only provides a stable mounting base for the first spring but also effectively limits its extension and contraction range, preventing excessive extension or displacement and ensuring that the elastic compression component is always in good working condition.

[0011] Optionally, one vertical edge of the door is rotatably connected to the opening edge of the mounting cavity, and the other vertical edge of the door is detachably connected to the box body. A guide plate is rotatably connected to the lower edge of the opening of the mounting cavity. The guide plate can rotate upward to a vertical position inside the box body and downward to a horizontal position flush with the bottom surface of the box body. When the guide plate is in the horizontal position, a guide slope is provided on its upper side, and the guide slope is inclined downward in the direction away from the box body when the guide plate is in this position.

[0012] By adopting the above technical solution, when in a horizontal position, the guide ramp on its upper side slopes downwards away from the enclosure, forming a natural transition ramp. When workers use the pallet jack to move the electrical cabinet, there is no need to build additional complex auxiliary devices. They only need to adjust the guide plate to be horizontal, and the pallet jack and electrical cabinet can be easily moved into the enclosure along the guide ramp, greatly reducing the installation difficulty, reducing the manpower and time consumption during the installation process, and effectively improving installation efficiency.

[0013] Optionally, an extension protrusion is fixed on the side of the guide plate near the housing, and an accommodating notch is provided on the lower edge of the opening of the mounting cavity for inserting and rotating the extension protrusion; the upper side of the extension protrusion is flush with the bottom wall of the mounting cavity when the guide plate is in a horizontal state.

[0014] By adopting the above technical solution, the extended convex plate is rotatably connected to the accommodating notch at the lower edge of the mounting cavity opening, making the guide plate rotation more stable and less prone to shaking or displacement, thus ensuring the precise positioning of the guide plate in different states. When the guide plate is in a horizontal state, the upper surface of the extended convex plate is flush with the bottom wall of the mounting cavity, forming a smooth transition surface. This avoids bumps or jamming when the pallet jack enters the cabinet through the guide plate, making the handling of the electrical cabinet more stable and smooth, further improving installation efficiency, and also reducing potential damage to the electrical cabinet caused by uneven handling, thus ensuring equipment safety.

[0015] Optionally, an adjusting rod is vertically fixed on both sides of the guide plate near the housing; the adjusting rod is horizontal when the guide plate is vertically upward, and vertically upward when it is horizontal; the bottom surface of the control rod abuts against the upper side of the adjusting rod when the adjusting rod is horizontal, and the bottom surface of the sealing seat and the upper side of the fixed seat abut against each other at this time; when the adjusting rod is vertically upward, it presses against the control rod, causing the sealing seat to rotate away from the fixed seat.

[0016] By adopting the above technical solution, when the guide plate is in a vertically upward state, the adjusting rod presses the control rod vertically upward, causing the sealing seat to move away from the fixed seat, facilitating the connection of external cables. When the guide plate is turned to a horizontal state for transporting the electrical cabinet, the adjusting rod becomes horizontal, the bottom surface of the control rod abuts against the upper side of the adjusting rod, and the bottom surface of the sealing seat abuts against the upper side of the fixed seat to form a seal. This not only does not affect the installation of the electrical cabinet, but also automatically seals the wiring port after installation, preventing external cables from being damaged by friction against the inner wall of the wiring port, thus improving the adaptability and safety of the ring main unit in different operating scenarios.

[0017] Optionally, a buffer pad is fixed on the upper surface of the adjusting rod when it is in a vertical position.

[0018] By adopting the above technical solution, the buffer pad can buffer and dampen shocks during the process of the adjusting rod pressing against the control rod, avoiding direct rigid contact between the adjusting rod and the control rod, reducing wear caused by collision, and extending the service life of the components. At the same time, the buffering effect can make the pressing of the adjusting rod against the control rod more stable and gentle, ensuring the stability of the rotation of the sealing seat, thereby ensuring that the sealing cavity can be reliably formed and closed, and improving the performance and safety of the ring main unit in the face of complex environments such as vibration.

[0019] Optionally, a positioning protrusion is fixed on the side of the fixed base facing the door, and a positioning notch is provided on the positioning protrusion for the horizontal adjustment rod to rotate into; an elastic snap-fit ​​is provided on the outer side of the adjustment rod, and a positioning groove is provided on the inner wall of the positioning notch for the elastic snap-fit ​​to snap into.

[0020] By adopting the above technical solution, when the guide plate is in a horizontal state and the adjusting rod rotates into the positioning notch of the positioning protrusion, the positioning notch can initially limit the adjusting rod, preventing it from shaking freely. The cooperation between the elastic snap-fit ​​component and the positioning groove further securely clamps the adjusting rod, ensuring the guide plate's position is accurate and stable in a horizontal state. This not only allows the guide plate to better fulfill its transition function during electrical cabinet handling but also prevents the sealing effect of the sealing seat and fixed seat from being affected by guide plate swaying, improving the overall stability and reliability of the ring main unit structure and ensuring the normal operation of the equipment in complex environments.

[0021] Optionally, a fixing plate is installed on the inner side of the box door, and a fixing notch is opened on the side of the fixing plate away from the box door; the bottom surface of the sealing seat abuts against the top surface of the fixing seat when the guide plate is in a vertical state, and the outer end of the control rod can be inserted into the fixing notch when the box door is closed, and the fixing plate further locks the state of the guide plate and the sealing seat at this time.

[0022] By adopting the above technical solution, when the guide plate is in a vertical position, the bottom surface of the sealing seat abuts against the top surface of the fixed seat. At this time, the box door is closed, and the outer end of the control rod is engaged in the fixing notch of the fixed plate. The fixed plate further locks the guide plate and the sealing seat in place. This effectively prevents the guide plate and the sealing seat from accidentally rotating or shifting due to external forces such as vibration during the use of the ring main unit. It ensures that the sealing seat is always in the correct position, maintains a good sealing effect at the connection port, avoids damage to external cables, ensures the stability and safety of power transmission, and extends the service life of the equipment.

[0023] Optionally, the door is provided with an observation opening and an observation window for sealing the observation opening is fixedly provided; the fixing plate is installed vertically on the inner side of the door, the fixing plate can slide back and forth in the horizontal direction, and a cleaning cotton is fixedly provided on the side of the fixing plate facing the door, the cleaning cotton can clean the inner side of the observation window when it slides back and forth with the fixing plate.

[0024] By adopting the above technical solution, the cabinet door is equipped with an observation port and observation window, allowing staff to easily check the internal condition of the cabinet and keep abreast of the equipment's operating status. The ingeniously designed fixed plate, which can slide back and forth horizontally, has cleaning cotton attached to it that automatically cleans the inside of the observation window during sliding, effectively removing dust and stains and maintaining the window's clarity and transparency. This eliminates the need for staff to use additional tools for cleaning, saving maintenance time and effort.

[0025] Optionally, two dovetail slide rails are fixedly mounted side by side along the horizontal direction on the inner side of the box door, and fixed sliders facing the box door are fixedly mounted on the upper and lower sides of the fixed plate, and dovetail grooves are opened on the two fixed sliders to slide and connect with the dovetail slide rails.

[0026] By adopting the above technical solution, the dovetail slide rails arranged side by side on the inner side of the door cooperate with the fixed sliders with dovetail grooves on the upper and lower edges of the fixed plate. The dovetail structure has a good limiting effect, which can prevent the fixed plate from falling off the slide rail during the sliding process and ensure that the fixed plate can only slide smoothly back and forth in the horizontal direction.

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

[0028] In environments with frequent vibrations, when an external cable is connected to the enclosure through the connector, the elastic compression component activates, causing the control lever to rotate towards the fixed seat, thus bringing the fixed seat and the sealing seat into contact. At this point, the two sealing notches together form a sealed cavity that coincides with the connector, and the elastic pads on the inner walls of the sealing notches tightly press against the outer circumference of the external cable. This design effectively prevents the external cable from frequently contacting and rubbing against the inner wall of the connector during vibrations, significantly reducing the possibility of damage or breakage to the insulation layer and other parts of the external cable due to long-term friction.

[0039] The present application will be further described in detail below with reference to all the accompanying drawings.

[0040] Example:

[0041] Reference Figure 1 An anti-vibration ring mesh box includes a box body 1, wherein an installation cavity 11 is provided on the front vertical surface of the box body 1, and a box door 2 is detachably installed to block the opening of the installation cavity 11. Connection ports 12 that communicate with the installation cavity 11 and are used for external cable access are provided on both the left and right sides of the box body 1.

[0042] One vertical edge of the door 2 is rotatably connected to the opening edge of the mounting cavity 11, and the other vertical edge of the door 2 is detachably connected to the box body 1 through a conventional lock structure. The installation method of the door 2 is a conventional structure, which will not be described in detail here.

[0043] Reference Figure 2 and Figure 3The inner wall of the housing 1 is provided with two sets of fixing components 3 located near the two wiring ports 12. The fixing components 3 include a fixing seat 31 fixed on the vertical inner wall of the housing 1 and located below the wiring port 12. A sealing seat 32 is rotatably connected to the upper edge of the fixing seat 31 away from the door 2. A sealing notch 321 is opened on the side of the fixing seat 31 and the sealing seat 32 that are close to each other. A rubber elastic pad 33 is fixed on the inner wall of the sealing notch 321.

[0044] A control rod 34 is fixedly mounted on the side of the sealing seat 32 facing the door 2, and an elastic compression member 35 is provided on the inner wall of the box body 1; wherein the elastic compression member 35 includes a first spring 351 in a compressed state and a limiting plate 352 fixed above the control rod 34, and the two ends of the first spring 351 are fixedly connected to the sides of the limiting plate 352 and the control rod 34 that are close to each other.

[0045] When the external cable is inserted into the housing 1 through the connector 12, the elastic compression member 35 drives the control rod 34 to rotate towards the fixed seat 31, so that the top surface of the fixed seat 31 and the bottom surface of the sealing seat 32 abut against each other. At this time, the two sealing notches 321 together form a sealing cavity that coincides with the connector 12, thereby pressing against the outer periphery of the external cable, reducing the impact of external vibration on the external cable, and improving the buffering and shock absorption performance of the cable.

[0046] Reference Figure 4 , Figure 5 and Figure 6 A guide assembly 4 is installed on the housing 1. The guide assembly 4 includes a guide plate 41 that is rotatably connected to the lower edge of the opening of the mounting cavity 11. An extension protrusion 42 is integrally formed on the side of the guide plate 41 near the housing 1. A receiving notch 13 is provided on the lower edge of the opening of the mounting cavity 11 for inserting the extension protrusion 42 and for rotatably connecting it.

[0047] The guide plate 41 can rotate upward to a vertical position within the housing 1 and downward to a horizontal position flush with the bottom surface of the housing 1. When the guide plate 41 is in a horizontal position, a guide slope 411 is provided on its upper side. The guide slope 411 is inclined downward in a direction away from the housing 1 when the guide plate 41 is in this position. When the guide plate 41 is in a horizontal position, the upper side of the extension protrusion 42 is flush with the bottom wall of the mounting cavity 11.

[0048] When using a pallet jack to install the electrical cabinet into the enclosure 1, the staff can adjust the guide plate 41 to a horizontal position, and then move the pallet jack along the guide ramp 411 into the enclosure 1, which can quickly install the electrical cabinet into the enclosure 1 and improve the corresponding installation efficiency.

[0049] Reference Figure 4 and Figure 5An adjusting rod 43 is vertically fixed on the side of the guide plate 41 near the box 1 on both sides; when the guide plate 41 is in a vertically upward state, the adjusting rod 43 itself is in a horizontal state; when the guide plate 41 is in a horizontal state, the adjusting rod 43 itself is in a vertically upward state, and a rubber buffer pad 431 is fixed on the upper surface of the adjusting rod 43 in a vertical state.

[0050] When the adjusting rod 43 is in a horizontal state, the bottom surface of the control rod 34 abuts against the upper side of the adjusting rod 43, and the bottom surface of the sealing seat 32 and the upper side of the fixed seat 31 abut against each other under the action of the elastic pressing member 35. When the adjusting rod 43 is in a vertical upward state, the buffer pad 431 at the upper end of the adjusting rod 43 presses against the bottom surface of the control rod 34, causing the sealing seat 32 to rotate away from the fixed seat 31. At this time, it is convenient for the external cable to be connected to the inside of the box 1 through the wiring port 12.

[0051] Reference Figure 5 and Figure 7 A positioning protrusion 36 is fixed on the side of the fixed base 31 facing the door 2. A positioning notch 361 is provided on the positioning protrusion 36 for the horizontal adjustment rod 43 to rotate into. An elastic snap-fit ​​member 44 is provided on the outer side of the adjustment rod 43. A positioning groove 362 is provided on the inner wall of the positioning notch 361 for the elastic snap-fit ​​member 44 to snap into.

[0052] The elastic snap-fit ​​component 44 includes a compression spring 441 and an arc-shaped protrusion 442. The adjusting rod 43 has a placement groove 432 for the compression spring 441 and the arc-shaped protrusion 442 to be placed. One end of the compression spring 441 presses against one side of the arc-shaped protrusion 442, causing a part of the arc-shaped protrusion 442 to protrude from the opening of the placement groove 432. The protruding part of the arc-shaped protrusion 442 is an arc surface, and the arc length corresponding to the arc surface is a minor arc.

[0053] When the adjusting rod 43 is in a horizontal state, the guide plate 41 is in a vertically upward state. At this time, the adjusting rod 43 rotates into the positioning notch 361, and the elastic snap-fit ​​44 simultaneously snaps into the positioning groove 362, thereby improving the installation stability when the guide plate 41 is in a vertically upward state.

[0054] Reference Figure 8 The door 2 has an observation opening 21 and an observation window 22 for sealing the observation opening 21. A fixing plate 5 is installed on the inner side of the door 2. The fixing plate 5 is installed vertically on the inner side of the door 2. The fixing plate 5 can slide back and forth in the horizontal direction. A cleaning cotton 52 is fixed on the side of the fixing plate 5 facing the door 2.

[0055] Two dovetail slide rails 23 are fixedly mounted side by side along the horizontal direction on the inner side of the door 2. Fixed sliders 53 facing the door 2 are fixedly mounted on the upper and lower edges of the fixed plate 5. The two fixed sliders 53 have dovetail grooves 531 that slide in conjunction with the dovetail slide rails 23, thus achieving a sliding connection between the fixed plate 5 and the door 2. When cleaning the inner wall of the observation window 22 is required, the operator can slide the fixed plate 5 back and forth, and then use cleaning cotton 52 to clean the inner surface of the observation window 22.

[0056] Reference Figure 6 and Figure 7 A fixing notch 51 is provided on the side of the fixing plate 5 away from the door 2. When the guide plate 41 is in a vertical state, the position of the fixing plate 5 is pre-adjusted by sliding. When the bottom surface of the sealing seat 32 abuts against the top surface of the fixing seat 31, the outer end of the control rod 34 can be inserted into the fixing notch 51 when the door 2 is closed. At this time, the fixing plate 5 is used to further lock the state of the guide plate 41 and the sealing seat 32, thereby improving the installation stability of the guide plate 41 and the sealing seat 32 in this state.

[0057] The implementation principle of this application embodiment is as follows:

[0058] When connecting external cables, the guide plate 41 is adjusted to a horizontal position, and the electrical cabinet is easily installed into the enclosure 1 using the guide ramp 411, which improves installation efficiency. At this time, the adjusting rod 43 is in a vertical upward position, and its upper buffer pad 431 presses the bottom surface of the control rod 34, causing the sealing seat 32 to rotate away from the fixed seat 31, so that the external cable can be connected to the inside of the enclosure 1 through the wiring port 12.

[0059] After the cable connection and electrical cabinet installation are completed, rotate the guide plate 41 upward to a vertical position. The adjusting rod 43 then becomes horizontal, and the bottom surface of the control rod 34 abuts against the upper side of the adjusting rod 43. Under the action of the elastic pressing member 35, the bottom surface of the sealing seat 32 and the upper side of the fixed seat 31 abut against each other. The two sealing notches 321 form a sealing cavity that coincides with the wiring port 12, pressing against the outer periphery of the external cable, reducing the impact of external vibration, and improving the cable's buffering and shock absorption performance. At the same time, the adjusting rod 43 rotates into the positioning notch 361 of the positioning protrusion 36, and the elastic snap-fit ​​member 44 snaps into the positioning groove 362, improving the stability of the guide plate 41 in a vertical state.

[0060] When the cabinet door 2 is closed, the outer end of the control lever 34 engages with the fixing notch 51 on the fixing plate 5, further locking the guide plate 41 and the sealing seat 32. Additionally, the cabinet door 2 is equipped with an observation window 22 for easy monitoring of the internal electrical cabinet's operation. When cleaning the inner wall of the observation window 22 is required, the cabinet door 2 is opened, and then the fixing plate 5 is controlled to slide back and forth horizontally. The cleaning cotton 52 on the fixing plate can then clean the inner wall of the observation window 22. The fixing plate 5 is slidably connected to the cabinet door 2 via a dovetail slide rail 23 and a fixed slider 53.
