Description

Technical Field

[0001] This invention relates to the technical field of dustproof and heat dissipation equipment for power metering boxes, specifically a dustproof and heat dissipation device for power metering boxes. Background Technology

[0002] Electricity metering boxes are devices used for metering electricity in 3-35kV three-phase power systems. They consist of combined instrument transformers, a box, an electricity meter, and surge arresters. These devices are mainly divided into three categories: oil-immersed, outdoor dry-type, and prepaid metering boxes. Oil-immersed boxes, represented by the JLS-35 model, use a V / V connection and are suitable for rural substations and industrial and mining enterprise power distribution stations. Outdoor dry-type models, such as the JLSZV-10, use epoxy resin casting technology and have oil-free characteristics. Prepaid types integrate vacuum circuit breakers and remote meter reading systems, supporting anti-theft and remote electricity purchase functions.

[0003] An existing dustproof and heat dissipation device for power metering boxes typically requires manual disassembly and cleaning of the box. The machine cannot clean and collect the dust inside the box, leading to dust accumulation over time. This affects the heat dissipation of the components and wastes a lot of manpower and time. Summary of the Invention

[0004] The purpose of this invention is to provide a dustproof and heat dissipation device for an electricity metering box to solve the problems mentioned in the background art.

[0008] Furthermore, there are several heat dissipation vents, the surface of the threaded rod is threadedly connected to the inner wall of the slider, the inner wall of the belt away from the first pulley is connected to the inner wall of the second pulley, the surface of the second soft brush is in contact with the inner wall of the box, the surface of the extrusion plate is adapted to the inner wall of the collection box, and the end of the limiting telescopic rod away from the extrusion plate is fixedly connected to the inner wall of the collection box.

[0009] Furthermore, the heat dissipation device includes a second motor, the surface of which is fixedly connected to the inner wall of the support frame, a long rod is fixedly connected to the inner wall of the heat dissipation frame, heat dissipation fins are fixedly connected to the surface of the long rod, a second rotating rod is fixedly connected to the output end of the second motor, fan blades are fixedly connected to the surface of the second rotating rod, and a heat dissipation base is fixedly connected to the bottom of the inner wall of the housing.

[0010] Furthermore, the long rod passes through the heat dissipation fins and extends to the bottom of the inner wall of the heat dissipation frame. There are several heat dissipation fins. The second rotating rod passes through the housing and extends to the outer end of the fan blade. The heat dissipation base is located below the power metering device.

[0011] Furthermore, the lifting and cooling device includes a slide rail, the surface of which is fixedly connected to the inner wall of the housing. A fixing ring is fixedly connected to the surface of the thin rod. An inclined plate is hinged to the end of the fixing ring away from the thin rod. A lifting plate is hinged to the end of the inclined plate away from the fixing ring. A lifting wheel is fixedly connected to the inner wall of the lifting plate. A fixed telescopic rod is fixedly connected to the bottom of the lifting wheel. A force-applying plate is fixedly connected to the top of the lifting plate. A lifting support is fixedly connected to the end of the force-applying plate away from the lifting plate.

[0012] Furthermore, the top of the lifting support frame is adapted to the bottom of the power metering device, the power metering device is located above the lifting support frame, the surface of the lifting wheel is slidably connected to the inner wall of the slide rail, and the end of the fixed telescopic rod away from the lifting wheel is fixedly connected to the inner wall of the slide rail.

[0013] The present invention has the following beneficial effects: When the motor of this invention is turned on, the output end drives the rotating rod to rotate. When the rotating rod rotates, it drives the threaded rod to rotate as well. When the threaded rod rotates, it drives the slider to move back and forth inside the slide groove through the thread. When the slider moves, it drives the cleaning brush and the soft brush to move together, so that the cleaning brush and the soft brush can clean the inner wall of the housing and the inner wall of the heat dissipation vent, so as to avoid the problem of dust accumulation affecting the heat dissipation of the machine and causing damage to the circuit. At the same time, when the soft brush moves, it drives the push plate to move and push away the dust that has fallen off after cleaning. When the rotating rod rotates, it drives the first pulley to rotate. The first pulley drives the second pulley to rotate on the surface of the support rod through the transmission belt. The second pulley drives the second threaded rod to rotate. When the second threaded rod rotates, it drives the second slider to move back and forth through the thread. The second slider drives the second soft brush to clean the inner wall of the housing. When the slider moves, it drives the squeezing plate through the thin rod to squeeze the dust that has fallen into the collection box, thereby increasing the collection space of the collection box. The limiting telescopic rod makes the position of the squeezing plate more stable when it moves.

[0014] When the second motor of this invention is turned on, the output end will drive the second rotating rod to rotate. When the second rotating rod rotates, it will drive the fan blades to rotate, so that the fan blades can blow air to cool the inside of the housing. At this time, the airflow blown out by the fan blades will be discharged through the heat dissipation fins, which improves the heat dissipation efficiency of the machine and avoids damage to the circuits due to slow heat dissipation. At the same time, the heat dissipation base will ventilate the bottom of the power metering device, preventing some parts from affecting heat dissipation and thus affecting the normal operation of the components.

[0015] When the thin rod moves, it drives the fixed ring to move as well. The fixed ring, in turn, presses against the inclined plate, causing the lifting plate to move up and down within the slide rail via the lifting wheel. The fixed telescopic rod ensures greater stability during the lifting wheel's movement, preventing the power metering device from falling and being damaged due to positional shift. The lifting plate's up-and-down movement also drives the lifting support frame to move up and down via the force plate. This lifting support frame, in turn, moves the power metering device above, allowing for sufficient heat dissipation from the device. This prevents heat dissipation dead zones caused by angle issues, avoiding problems such as short circuits over time and improving the component's lifespan.

[0016] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Heat dissipation fins 52 are fixedly connected to the surface of the long rod 51. The output end of the second motor 50 is fixedly connected to the second rotating rod 53. When the second rotating rod 53 rotates, it drives the fan blades 54 to rotate, so that the fan blades 54 can blow air to dissipate heat inside the housing 1. The surface of the second rotating rod 53 is fixedly connected to the fan blades 54. The airflow blown out by the fan blades 54 will be discharged through the heat dissipation fins 52. A heat dissipation base 55 is fixedly connected to the bottom of the inner wall of the housing 1. The heat dissipation base 55 will provide ventilation to the bottom of the power metering device 4.

[0027] The lifting and cooling device 9 includes a slide rail 60, the surface of which is fixedly connected to the inner wall of the housing 1. A fixing ring 62 is fixedly connected to the surface of the thin rod 39. When the fixing ring 62 moves, it presses against the inclined plate 63, causing the inclined plate 63 to press against the lifting plate 66, thereby driving the lifting plate 66 to move up and down inside the slide rail 60 via the lifting wheel 64. The end of the fixing ring 62 away from the thin rod 39 is hinged to the inclined plate 63, and the end of the inclined plate 63 away from the fixing ring 62 is hinged to the lifting plate 66.

The rotation of the threaded rod 29, in turn, causes the slider 23 to move back and forth within the slide groove 21 via the thread. As the slider 23 moves, it moves the cleaning brush 24 and the soft brush 25 together, allowing them to clean the inner walls of the housing 1 and the heat dissipation vent 28. This prevents dust accumulation from affecting the machine's heat dissipation and causing damage to the wiring. Simultaneously, the movement of the soft brush 25 moves the push plate 26, which pushes away the dust that has fallen off during cleaning. The rotating rod 30 rotates... When in motion, the first pulley 31 rotates, and the first pulley 31 drives the second pulley 34 to rotate on the surface of the support rod 33 via the transmission belt 32. This causes the second pulley 34 to drive the second threaded rod 35 to rotate. When the second threaded rod 35 rotates, it drives the second slider 36 to move back and forth via the thread.

When the slider 23 moves, it drives the squeezing plate 40 via the thin rod 39 to squeeze the dust that falls into the collection box 38, increasing the collection space of the collection box 38. When the limiting telescopic rod 41 moves the squeezing plate 40, With a more stable position, when the second motor 50 is turned on, its output will drive the second rotating rod 53 to rotate.

The airflow from the fan blades 54 will be exhausted through the heat dissipation fins 52, improving the machine's heat dissipation efficiency and preventing damage to wiring due to slow heat dissipation. Simultaneously, the heat dissipation base 55 will provide ventilation to the bottom of the power metering device 4, preventing some areas from affecting heat dissipation and thus the normal operation of the components. When the thin rod 39 moves, it will drive the fixed ring 62 to move as well. When the fixed ring 62 moves, it will... The inclined plate 63 presses against the lifting plate 66, thereby causing the lifting plate 66 to move up and down inside the slide rail 60 via the lifting wheel 64. The fixed telescopic rod 65 makes the movement of the lifting wheel 64 more stable, preventing the power metering device 4 from falling and being damaged due to positional deviation. When the lifting plate 66 moves up and down, it will drive the lifting support frame 61 to move up and down through the force plate 67. The lifting support frame 61 will then drive the power metering device 4 above to move together, allowing the machine to fully dissipate heat from the power metering device 4, avoiding heat dissipation dead angles due to angle issues, and preventing problems such as short circuits caused by long-term operation, thus improving the service life of the components.
