Description

Technical Field

[0001] This application relates to power system distribution equipment, and more particularly to a primary and secondary integrated ring main unit with good dust protection. Background Technology

[0002] As a core piece of equipment in the power distribution system, the integrated primary and secondary ring main unit belongs to the field of power distribution equipment technology. Its main function is to integrate primary and secondary equipment modules, and through their collaborative work, achieve flexible control, fault isolation, and operation monitoring of the distribution network. It is a key infrastructure to ensure the safe, stable, and efficient operation of the distribution network. Since this equipment is mostly installed in outdoor or semi-outdoor environments, it is exposed to air containing dust and impurities for a long time. The insulation performance of the contacts of the primary equipment and the sensitivity of the circuit boards of the secondary equipment inside the box are easily affected by dust. At the same time, the heat generated during the operation of the equipment needs to be dissipated in a timely manner through ventilation. Therefore, ventilation and heat dissipation and dust protection have become the two core requirements to ensure its long-term reliable operation.

[0003] Existing integrated primary and secondary ring main units have significant shortcomings in their coordinated design for ventilation and dust prevention, making it difficult to meet both requirements simultaneously. Specifically, there is a general contradiction between the ventilation structure and dust prevention design of existing ring main units. Some products prioritize heat dissipation efficiency by using fixed vents or semi-open baffle designs. Even during non-ventilation periods, the vents remain semi-open, allowing external dust to continuously intrude into the enclosure and gradually adhere to the conductive contacts of primary equipment and the surfaces of precision components in secondary equipment. This not only reduces the insulation performance of the equipment and increases the risk of short circuits or poor contact, but may also block the heat dissipation channels, exacerbating the heat dissipation problem.

[0004] Addressing the core issue of the difficulty in coordinating ventilation and dust prevention in existing integrated primary and secondary ring main units, this application proposes an integrated primary and secondary ring main unit with excellent dust prevention. Its core innovation lies in the fact that when the ring main unit generates heat due to equipment operation and requires ventilation and heat dissipation, the baffle can be flexibly opened, forming an efficient air circulation channel with the ventilation components inside the unit to quickly remove heat from the unit and ensure stable equipment operation. When the ring main unit does not require ventilation, the baffle can be automatically or manually closed tightly, and the sealing structure further blocks the path of external dust into the unit, effectively preventing dust intrusion. Utility Model Content

[0005] The purpose of this application is to provide a primary and secondary integrated ring network box with good dustproof performance, which solves the problem that existing primary and secondary integrated ring network boxes cannot simultaneously achieve ventilation and heat dissipation and dust protection.

[0006] The dustproof primary and secondary fusion ring network box provided in this application adopts the following technical solution: it includes a box body, a top cover assembly and a ventilation assembly. The top cover assembly is set on the top of the box body, and the ventilation assembly is set on the bottom of the box body. Uprights are set at the top of the top of the top cover assembly near the four corners, and two sets of inclined plates are set on the top of the uprights. The ventilation assembly includes a frame, with grooves on both sides of the inner wall of the frame. A set of the grooves contains a bidirectional lead screw, and the surface of the bidirectional lead screw is threaded with two sets of threaded blocks. A baffle is provided on one side of each set of threaded blocks. A second drive motor is provided on one side of the frame, and the other end of the output shaft of the second drive motor is fixedly connected to the shaft end of the bidirectional lead screw.

[0007] By adopting the above technical solution, the uprights at the four corners of the top of the top cover assembly support two sets of inclined plates. The inclined plates can effectively block dust, rainwater and other impurities falling from the top, reducing the direct adhesion of impurities to the surface of the top cover assembly. The second drive motor can drive the bidirectional lead screw to rotate, causing the two sets of threaded blocks connected by the surface threads to move closer or further away synchronously, thereby driving the two sets of baffles to open and close. When the equipment inside the enclosure needs to dissipate heat, the baffles open under the drive action to ensure that the bottom ventilation channel is unobstructed and meets the heat dissipation requirements. When ventilation is not required, the baffles close to directly block the bottom ventilation opening and prevent external dust from entering the enclosure from the bottom. Compared with the existing fixed ventilation openings or semi-open baffles, this structure realizes the automatic and flexible opening and closing of the baffles, and can be adjusted in real time according to the heat dissipation requirements inside the enclosure.

[0008] Preferably, another set of grooves is provided with a slide rod, and two sets of slide plates are slidably connected to the surface of the slide rod. One side of each set of slide plates is fixedly connected to the bottom of two sets of baffles.

[0009] By adopting the above technical solution, the sliding rod in the groove cooperates with the sliding plate. The sliding plate is fixed at the bottom of the baffle and slides along the sliding rod, which can provide stable guidance and support for the baffle during the opening and closing process, and avoid the baffle from moving, deviating or getting stuck because it only relies on the threaded block for driving.

[0010] Preferably, a set of grooves are provided on both sides of the inner wall of the groove, and a slider is slidably connected in the groove, and the slider is fixedly connected to one side of the threaded block.

[0011] By adopting the above technical solution, the sliding groove cooperates with the slider on one side of the threaded block. The slider slides along the sliding groove, which can limit the movement of the threaded block and prevent it from rotating.

[0012] Preferably, a sealing groove and a sealing plate are respectively provided on one side of the two sets of baffles, and the sealing groove and the sealing plate are adapted to each other.

[0013] By adopting the above technical solution, the sealing grooves and sealing plates of the two sets of baffles are respectively matched. When the baffles are closed, the sealing plate can be embedded in the sealing groove to fill the joint gap between the two sets of baffles.

[0014] Preferably, the top cover assembly includes a cover, the top of the cover is provided with two sets of gear frames that mesh with each other, the top of the cover is provided with a pinion that meshes with a gear frame, the bottom of the cover is provided with a first drive motor, the other end of the output shaft of the first drive motor is provided at the bottom of the pinion via a rotating shaft, and the bottom of the cover is provided with two sets of perforated plates, each set of perforated plates having a first filter screen at its bottom.

[0015] By adopting the above technical solution, the first drive motor drives the pinion to rotate through the shaft. The pinion drives the meshing gear frame, which in turn drives another set of meshing gear frames to move in tandem. This enables control over the opening and closing state of the perforated plate. When ventilation needs to be enhanced, the perforated plate opens, forming stronger air convection in conjunction with the bottom ventilation components. At the same time, the second filter at the bottom of the perforated plate can filter the air entering from the top, intercepting dust particles in the air and preventing dust from entering the interior of the housing through the perforated plate.

[0016] Preferably, support rods are provided at the bottom of the frame near the four corners, and each support rod has a base at its bottom.

[0017] By adopting the above technical solution, the support rods at the four corners of the bottom of the frame support the frame, keeping the ventilation components at a certain distance from the ground, thus preventing dust and water from the ground from directly contacting the bottom structure of the ventilation components.

[0018] Preferably, the frame is provided with multiple sets of mounting brackets; each mounting bracket is provided with a fan at the top, the frame is provided with a second filter at the bottom, and the surface of the box is movably connected with two sets of doors via hinges.

[0019] By adopting the above technical solution, the blower on the mounting bracket inside the frame can accelerate the airflow. When the baffle is opened, the blower can force the outside air filtered by the first filter into the box, and at the same time drive the hot air inside the box to be discharged from the top cover assembly.

[0020] In summary, this application includes at least one of the following beneficial technical effects: This dustproof primary and secondary fusion ring mesh box uses a second drive motor to drive a bidirectional lead screw to rotate, causing two sets of threaded blocks connected by threads on the surface to move synchronously closer or further away, thereby driving two sets of baffles to open and close. When the equipment inside the box needs heat dissipation, the baffles open under the drive action to ensure unobstructed ventilation channels at the bottom and meet heat dissipation requirements. When ventilation is not required, the baffles close to directly block the bottom ventilation openings, preventing external dust from entering the box from the bottom. Compared with existing fixed ventilation openings or semi-open baffles, this structure enables automatic and flexible opening and closing of the baffles, which can be adjusted in real time according to the heat dissipation requirements inside the box. The first drive motor drives a small gear to rotate through a rotating shaft. The small gear drives a meshing gear frame, which in turn drives another set of meshing gear frames to move in tandem, enabling control of the opening and closing state of the perforated plate. When stronger ventilation is needed, the perforated plate opens, forming stronger air convection in conjunction with the bottom ventilation components. At the same time, the second filter at the bottom of the perforated plate can filter the air entering from the top, intercepting dust particles in the air and preventing dust from entering the box through the perforated plate.

[0023] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.

[0024] Example 1: A primary and secondary fusion ring network box with good dustproof performance, referring to... Figure 1The device includes a housing 1, a top cover assembly 2, and a ventilation assembly 4. The top cover assembly 2 is located on the top of the housing 1, and the ventilation assembly 4 is located on the bottom of the housing 1. Uprights 7 are provided near the four corners of the top of the top of the top cover assembly 2. Two sets of inclined plates 8 are provided on the top of the uprights 7. The uprights 7 at the four corners of the top of the top cover assembly 2 support the two sets of inclined plates 8. The inclined plates 8 can effectively block dust, rainwater and other impurities falling from the top, reducing the direct adhesion of impurities to the surface of the top cover assembly 2.

[0025] Example 2: A primary and secondary fusion ring network box with good dustproof performance. Figure 1 , Figure 4 and Figure 5 The ventilation component 4 includes a frame 401. Grooves 402 are formed on both sides of the inner wall of the frame 401. A bidirectional lead screw 409 is installed in one set of grooves 402. Two sets of threaded blocks 410 are threadedly connected to the surface of the bidirectional lead screw 409. A baffle 406 is provided on one side of each set of threaded blocks 410. A second drive motor 415 is installed on one side of the frame 401. The other end of the output shaft of the second drive motor 415 is fixedly connected to the shaft end of the bidirectional lead screw 409. The second drive motor 415 can drive the bidirectional lead screw 409 to rotate, causing the two sets of threaded blocks 410 to move closer or further away synchronously, thereby causing the two sets of baffles 406 to open and close. When the equipment inside the enclosure 1 needs heat dissipation, the baffles 406 open under the drive action, ensuring unobstructed bottom ventilation channels and meeting heat dissipation requirements. When ventilation is not required, the baffles 406 close, directly blocking the bottom ventilation opening and preventing external dust from entering the enclosure 1 from the bottom. Compared with existing fixed ventilation openings or semi-open baffles 406, this... The structure enables automatic and flexible opening and closing of the baffle 406, which can be adjusted in real time according to the heat dissipation requirements inside the housing 1. A sliding rod 403 is installed in another set of grooves 402. Two sets of sliding plates 404 are slidably connected to the surface of the sliding rod 403. One side of each set of sliding plates 404 is fixedly connected to the bottom of the two sets of baffles 406. The sliding rod 403 in the groove 402 cooperates with the sliding plate 404. The sliding plate 404 is fixed to the bottom of the baffle 406 and slides along the sliding rod 403, which can provide heat dissipation during the opening and closing of the baffle 406. It provides stable guidance and support, preventing the baffle 406 from shifting or jamming due to relying solely on the threaded block 410 for drive. Both sides of the inner wall of a set of grooves 402 are provided with sliding grooves 412, and sliders 411 are slidably connected in the sliding grooves 412. The sliders 411 are fixedly connected to one side of the threaded block 410. The sliding grooves 412 cooperate with the sliders 411 on one side of the threaded block 410. The sliders 411 slide along the sliding grooves 412, which can limit the movement of the threaded block 410 and prevent it from rotating.

[0026] Example 3: A primary and secondary fusion ring network box with good dustproof performance. Figure 2 , Figure 3 and Figure 5Each of the two sets of baffles 406 has a sealing groove 407 and a sealing plate 408 on one side. The sealing groove 407 and the sealing plate 408 are adapted to each other. When the baffles 406 are closed, the sealing plate 408 can be embedded in the sealing groove 407 to fill the gap between the two sets of baffles 406. The top cover assembly 2 includes a cover 201. The top of the cover 201 is provided with two sets of gear frames 202, which mesh with each other. The top of the cover 201 is provided with a pinion 203. 3. A gear frame 202 meshes with the cover 201. A first drive motor 206 is provided at the bottom of the cover 201. The other end of the output shaft of the first drive motor 206 is provided at the bottom of the pinion 203 via a rotating shaft. Two sets of perforated plates 204 are provided at the bottom of the cover 201. A first filter screen 205 is provided at the bottom of each set of perforated plates 204. The first drive motor 206 drives the pinion 203 to rotate via the rotating shaft. The pinion 203 drives the meshing gear frame 202, thereby driving the other set of meshing gear frames 202 in conjunction, which can realize the opening and closing state of the perforated plates 204. When ventilation needs to be strengthened, the perforated plate 204 opens, forming a stronger air convection in conjunction with the bottom ventilation component 4. Simultaneously, the second filter 413 at the bottom of the perforated plate 204 filters the air entering from the top, intercepting dust particles and preventing dust from entering the housing 1 through the perforated plate 204. Support rods 5 are installed near the four corners of the bottom of the frame 401, and bases 6 are installed at the bottom of each support rod 5. The support rods 5 at the four corners of the bottom of the frame 401 support the frame 401, keeping the ventilation component 4 a certain distance from the ground to prevent dust from the ground from entering. Water directly contacts the bottom structure of the ventilation component 4. Multiple sets of mounting brackets 405 are installed inside the frame 401. Each mounting bracket 405 is equipped with a blower 414 on its top. A second filter 413 is installed at the bottom of the frame 401. Two sets of doors 3 are connected to the surface of the housing 1 by hinges. The blower 414 on the mounting bracket 405 inside the frame 401 can accelerate airflow. When the baffle 406 is opened, the blower 414 can force the outside air filtered by the first filter 205 into the housing 1, while driving the hot air inside the housing to be discharged from the top cover component 2.

[0027] The implementation principle of this application embodiment is as follows: First, the ring mesh box is stably placed by the support rods 5 at the four corners of the bottom frame 401 and the base 6. The uprights 7 at the four corners of the top of the top cover assembly 2 support two sets of inclined plates 8, which can block the dust falling from the top in real time. When the primary and secondary equipment inside the box 1 generates heat and ventilation is required, the second drive motor 415 will start first. Its output shaft drives the bidirectional lead screw 409 in a set of grooves 402 in the ventilation assembly 4 frame 401 to rotate. Since the two sets of threaded blocks 410 connected to the surface of the bidirectional lead screw 409 have a slider 411 fixed on one side, the slider 411 can slide in the groove 4 on the inner wall of the groove 402. The sliding mechanism 12 effectively restricts the rotation of the threaded block 410 and guides its axial movement along the bidirectional lead screw 409. Simultaneously, the sliding plate 404 at the bottom of the baffle 406 slides stably along the sliding rod 403 in another set of grooves 402, preventing the baffle 406 from shifting or jamming. Ultimately, this causes both sets of baffles 406 to open synchronously to both sides, opening the bottom ventilation channel. Subsequently, the blower 414 on the mounting bracket 405 inside the frame 401 starts. Outside air undergoes preliminary filtration through the first filter 205 at the bottom of the frame 401, intercepting large dust particles, before being forcibly blown into the housing 1 by the blower 414. At the same time, the first drive motor 2 at the bottom of the cover 201... 06 drives the small gear 203 to rotate via the rotating shaft. The small gear 203 drives a set of gear frames 202 that mesh with it. This gear frame 202 then drives another set of meshing gear frames 202 in conjunction, thereby controlling the opening of the two sets of perforated plates 204 at the bottom of the cover 201. This forms an efficient airflow path with bottom air intake, internal convection, and top air exhaust. When the hot air inside the box is discharged through the perforated plates 204, it will be filtered again by the second filter 413 at the bottom of the perforated plates 204 to prevent dust from flowing back into the box 1 with the hot air, ensuring the cleanliness of the air entering the box 1, quickly removing the heat generated by the equipment operation, and ensuring stable operation of the equipment. When the box 1 is equipped with When the heat is reduced and continuous ventilation is no longer needed, the second drive motor 415 will rotate in reverse, driving the bidirectional lead screw 409 to rotate in reverse, causing the two sets of threaded blocks 410 to bring the baffles 406 closer together until they are completely closed. At this time, the sealing plate 408 on one set of baffles 406 will be precisely embedded in the sealing groove 407 of the other set of baffles 406, filling the gap at the joint of the baffles 406. At the same time, the first drive motor 206 rotates in reverse, controlling the perforated plate 204 to close through the gear frame 202, forming a cooperation with the sealing structure of the baffles 406, realizing the double sealing of the upper and lower ventilation channels of the housing 1, minimizing dust intrusion during non-ventilation periods.
