Description

Electric shock protection safety energy metering box Technical Field

[0001] This application relates to the technical field of electricity metering boxes, and in particular to electric shock-proof safety electricity metering boxes. Background Technology

[0002] An electricity metering box is a collection of metering instruments and auxiliary equipment necessary for measuring electrical energy. It mainly includes electricity meters, voltage and current transformers and their secondary circuits, electricity metering panels, cabinets, boxes, etc.

[0003] Existing metal electricity metering boxes are generally made of metal to adapt to different environments. However, appropriate insulation protection should be provided inside the box to prevent electric shock. As described in patent application number CN202320227596.3, an insulating protective shell is installed inside the box and fixedly installed inside the box.

[0004] Regarding the aforementioned technologies, when the electrical components inside the electricity metering box are working, they will generate heat. When the box is dissipating heat, the insulating protective shell has a certain blocking effect, and the heat dissipation effect of the box needs to be improved. Summary of the Invention

[0005] In order to improve the heat dissipation effect while protecting the electricity meter box from electric shock, this application provides an electric shock-proof safety electricity meter box.

[0006] This application provides a shockproof safety energy metering box, which adopts the following technical solution:

[0007] An electric shock-proof safety energy metering box includes a box body and an insulating mounting frame installed inside the box body. The mounting frame includes a bottom plate and a top plate, and a heat dissipation rack installed between the bottom plate and the top plate. The heat dissipation rack includes at least two rows of mounting rods, with multiple mounting rods in each row spaced apart. Each mounting rod is connected in series with multiple spherical structures. Adjacent spherical structures on the same mounting rod are tangent to each other, and spherical structures between adjacent mounting rods in the same row are tangent to each other. The center heights of adjacent spherical structures in adjacent rows of mounting rods are different. A mounting base is installed on the heat dissipation rack. The bottom plate, top plate, and heat dissipation rack are all spaced from the inner wall of the box body, and a support rod connects the bottom plate and the bottom wall of the box body.

[0008] By adopting the above technical solution, the metering box isolates the internal electronic components from the box body through an insulated mounting frame, effectively preventing the risk of electric shock. At the same time, the spherical structure on the heat dissipation rack increases the heat dissipation area and improves the heat dissipation efficiency. The adjacent spherical structures are all in a tangent state and the center height of the two adjacent rows of spheres is different. When the side wall of the box body near the heat dissipation rack has a ventilation section, the heat dissipation rack can not only dissipate heat but also play a blocking role. External wind and rain will not directly contact the heat dissipation rack and the mounting base, thus improving the overall safety performance of the electricity metering box.

[0009] Optionally, multiple spheres are slidably mounted on the mounting rod, and a pressing block is helically mounted on one end of the mounting rod, with the pressing block abutting against the sphere structure.

[0010] By adopting the above technical solution, the spherical structure can slide freely on the mounting rod and be limited by the pressure block. This design allows the spherical structure to slide and be fixed on the mounting rod.

[0011] Optionally, the mounting base includes a mounting ring and a mounting plate, the mounting plate and the mounting ring being fixedly connected, the mounting ring having a through hole for the mounting rod to pass through and a clearance groove for contacting the outer wall of the plurality of spherical structures.

[0012] By adopting the above technical solution, the mounting base provides a stable installation foundation through the fixed connection of the mounting ring and the mounting plate; the design of the perforation and clearance groove allows the mounting base to fit tightly against the spherical structure on the heat sink, ensuring the stable installation of the connector.

[0013] Optionally, the mounting plate has a groove on one side wall near the mounting ring.

[0014] By adopting the above technical solution, the groove wall of the mounting plate can also contact the spherical structure, thereby enhancing the stability of the mounting base.

[0015] Optionally, the mounting base is installed on the mounting rods in the same row, and the lower end of the mounting rods in the same row is connected to a linkage rod. The linkage rod is in sliding contact with the base plate, and the linkage rod slides closer to or further away from the mounting rods in other rows.

[0016] By adopting the above technical solution, the linkage rod connects the mounting rods in the same row and allows them to slide relative to the base plate. This design allows the heat sink rack to be adjusted as needed to adapt to different working environments or heat dissipation requirements. When the spherical structures of the two rows of mounting rods approach each other, the two rows of spherical structures limit each other. When the linkage rod moves one row of mounting rods away from the other row of mounting rods, the rotating abutment block leaves the spherical structure, allowing the spherical structure to be moved and the installation position of the mounting base to be adjusted.

[0017] Optionally, a first wiring port is provided on the base plate, a second wiring port is provided on the bottom wall of the box, the support rod is a hollow structure with openings at both ends, one end of the support rod is connected to the first wiring port, the other end of the support rod is connected to the second wiring port, and a sealing component is provided on the outer wall of the box at the second wiring port.

[0018] By adopting the above technical solution, not only is a passageway for the wires to pass through provided, but the sealing component also prevents the intrusion of external dust and moisture.

[0019] Optionally, the support rod includes a first support half-ring and a second support half-ring, the first support half-ring being fixedly installed on the base plate, and the second support half-ring being rotatably installed on the first support half-ring.

[0020] By adopting the above technical solution, the cooperation between the first support half-ring and the second support half-ring allows the wire to be exposed or wrapped.

[0021] Optionally, the sealing assembly includes filler particles and an installation cylinder for holding the filler particles. The outer wall of the installation cylinder has a variable diameter structure, and the end of the installation cylinder with the larger outer diameter is fixedly connected to the box body.

[0022] By adopting the above technical solution, the filling particles can be filled into the installation cylinder, and the wire can be led out through the installation cylinder; this design not only ensures the safe exit of the wire, but also prevents the intrusion of external dust and moisture.

[0023] In summary, this application includes at least one of the following beneficial effects:

[0024] 1. The design of the insulated mounting frame, heat dissipation rack, and spherical structure effectively prevents the risk of electric shock, significantly improves heat dissipation efficiency, and extends the service life of the equipment;

[0025] 2. The mounting position is adjustable, enhancing the installation flexibility of the mounting base;

[0026] 3. The support rod can support the insulated mounting frame and the wires, and can also be used with the sealing components to reduce the entry of mosquitoes and external dust. Attached Figure Description

Detailed Implementation

[0037] The present application will be further described in detail below with reference to Figures 1-9.

[0038] This application discloses an anti-electric shock safety energy metering box. Referring to Figure 1, the anti-electric shock safety energy metering box includes a box body 100 and an insulating mounting frame 200 installed inside the box body 100. The mounting frame 200 includes a bottom plate 210 and a top plate 220, and a heat dissipation rack 230 installed between the bottom plate 210 and the top plate 220. A mounting seat 300 for mounting electrical components is installed on the heat dissipation rack 230. The bottom plate 210, top plate 220, and heat dissipation rack 230 are all spaced from the inner wall of the box body 100. Support rods 240 are connected to the bottom wall of the box body 100. Multiple support rods 240 are provided to ensure that the mounting frame 200 can be stably installed inside the box body 100. When electrical components are mounted on the heat dissipation rack 230 via the mounting seat 300, the heat dissipation rack 230 can provide good heat dissipation when the electrical components are working.

[0039] Referring to Figures 2 and 3, the heat sink 230 includes at least two rows of mounting rods 231, and in this embodiment, two rows of mounting rods 231 are preferred. Multiple mounting rods 231 in each row are spaced apart along the length of the base plate 210, and adjacent mounting rods 231 in the two rows are staggered. Multiple spherical structures 232 are connected in series on each mounting rod 231, and the spherical structures 232 have the same outer diameter. Adjacent spherical structures 232 on the same mounting rod 231 are tangent, and the spherical structures 232 on adjacent mounting rods 231 in the same row are tangent. The centers of adjacent spherical structures 232 on adjacent mounting rods 231 in the same row are at the same height. To make the center heights of adjacent spherical structures 232 in the two rows of mounting rods 231 different, the starting positions of the spherical structures 232 on adjacent mounting rods 231 in the two rows of mounting rods 231 are different. One row of mounting rods 231 has a pad 233 connected to its lower end, and the pad 233 contacts the first spherical structure 232 at the lower end of the mounting rod 231. The side wall of the enclosure 100 has a heat dissipation groove 110. If wind or dust enters the enclosure 100 through the heat dissipation groove 110, the spherical structures 232 on the two rows of mounting rods 231 will be tangent to each other, causing the meter to be mounted on the heat dissipation bracket 230. The heat dissipation bracket 230 not only provides heat dissipation but also acts as a barrier.

[0040] Referring to Figures 2 and 3, the lower end of one row of mounting rods 231 is connected to a linkage rod 235. The linkage rod 235 slides in contact with the base plate 210, and can slide closer to or further away from other rows of mounting rods 231. In this embodiment, the row of mounting rods 231 near the mounting base 300 is slidably mounted on the base plate 210. A groove 221 is provided on the lower surface of the top plate 220. The upper end of the mounting rod 231 extends into the groove 221, and then the lower end of the mounting rod 231 is fixedly connected to the linkage rod 235. When the linkage rod 235 slides, the upper end face of the mounting rod 231 slides in contact with the bottom wall of the groove 221. A receiving groove 212 is provided on the upper surface of the base plate 210, and the linkage rod 235 is located in the receiving groove 212. A guide rod 211 passes through the base plate 210 and passes through the linkage rod 235. The length direction of the guide rod 211 is the same as the sliding direction of the linkage rod 235. The guide rod 211 guides the linkage rod 235, allowing the linkage rod 235 to slide stably within the receiving groove 212.

[0041] Referring to Figure 3, a pressing block 234 is installed on the upper end of the mounting rod 231. The pressing block 234 is threadedly connected to the mounting rod 231, and the pressing block 234 contacts the uppermost spherical structure 232 of the mounting rod 231, thus limiting the spherical structure 232. If the pressing block 234 is rotated away from the spherical structure 232, the sphere can slide up and down on the mounting rod 231.

[0042] Referring to Figure 4, when the linkage rod 235 moves the ball structure 232 of one row of mounting rods 231 away from the ball structure 232 of another row of mounting rods 231, rotating the pressing block 234 away from the ball structure 232 can realize the up and down sliding of the ball structure 232.

[0043] Referring to Figures 5 and 6, the mounting base 300 includes a mounting ring 310 and a mounting plate 320, which are fixedly connected to the outer wall of the mounting plate 320 and the mounting ring 310. The mounting ring 310 has a through hole 311 for the mounting rod 231 to pass through, and a clearance groove 312 for contacting the outer wall of the spherical structure 232. When the mounting base 300 is mounted on the heat sink 230, the mounting rod 231 passes through the mounting ring 310, and the mounting ring 310 is installed between the two spherical structures 232, which remain tangent to each other. The spherical structure 232 contacts the inner wall of the clearance groove 312. The spherical structure 232 limits and fixes the mounting ring 310, ensuring its secure installation between the two spheres. By installing the mounting base 300, its position can be adjusted as needed, improving the flexibility of its position adjustment.

[0044] Referring to Figure 6, the mounting ring 310 may have a notch 313, through which the mounting rod 231 can directly enter the mounting ring 310. When adjusting the position of the mounting base 300, simply move the linkage rod 235 and the pressing block 234 appropriately to allow the ball structure 232 to move up and down. When installing the mounting ring 310, the ball structure 232 does not need to leave the mounting rod 231, which facilitates the connection of the mounting ring 310.

[0045] A mounting base 300 is provided with at least two mounting rings 310. In this embodiment, there are two mounting rings 310. When the mounting rings 310 are vertically distributed on the mounting plate 320, the two mounting rings 310 are simultaneously mounted on different spherical structures 232 of the same mounting rod 231. When the mounting rings 310 are horizontally distributed on the mounting plate 320, the two mounting rings 310 are respectively mounted on different mounting rods 231. Multiple mounting rings 310 are provided so that the mounting base 300 can be stably mounted on the heat sink 230.

[0046] The mounting plate 320 features a perforated structure for heat dissipation. Preferably, this perforated structure consists of an array of threaded holes 321, with bolts 322 threaded into these holes. The array of threaded holes 321 facilitates the installation of different types of electrical components and also aids in heat dissipation. Electrical components are typically mounted to the housing 100 using bolts 322. For example, before installing an electricity meter, a meter connector 400 is threaded into it. The meter connector 400 has a slotted hole for the bolts 322 to pass through, which then secures the meter connector 400 to the mounting plate 320. The mounting base 300 and the heat sink 230 facilitate the installation of electronic components, allow for easy repositioning of components according to circuit planning, and provide excellent heat dissipation.

[0047] Referring to Figure 5, a groove 323 is provided on one side wall of the mounting plate 320 near the mounting ring 310. When the mounting base 300 is installed on the heat sink 230, the spherical structure 232 and the inner wall of the groove 323 of the mounting plate 320 are in contact, which increases the stability of the mounting plate 320.

[0048] Referring to Figure 7, the base plate 210 has multiple first wiring ports 213, and the inner bottom wall of the housing 100 has a second wiring port 120. The support rod 240 is a hollow structure with openings at both ends. The upper end of the support rod 240 is connected to the first wiring port 213, and the lower end of the support rod 240 is connected to the second wiring port 120. The support rod 240 guides and limits the wires. A sealing assembly is provided on the outer wall of the housing 100 at the second wiring port 120. The sealing assembly includes filling particles and an installation cylinder 500 for holding the filling particles. One end of the installation cylinder 500 is fixedly installed on the outer wall of the housing 100. The installation cylinder 500 has a variable diameter structure. The outer diameter of the end of the installation cylinder 500 closer to the housing 100 is larger, and the outer diameter of the end of the installation cylinder 500 farther from the housing 100 is smaller. The opening with the smaller outer diameter allows only the power supply wire to pass through, and the filling particles can only be filled into the installation cylinder 500. The filling particles are not shown in the embodiments of this application. The filling particles can be granular activated carbon desiccant. The activated carbon desiccant is made from high-quality wood chips, coconut shells and other raw materials. It is processed by high-temperature activation and special pore size adjustment process. It has a large specific surface area and rich medium and micro pore structure. It can not only effectively remove moisture, but also adsorb odors and pollutants. It is suitable for moisture prevention and purification of electrical boxes.

[0049] Referring to Figures 8 and 9, to facilitate the filling of the filling particles, the support rod 240 includes a first support semi-ring 241 and a second support semi-ring 242. The upper end of the first support semi-ring 241 is fixedly installed on the base plate 210, and the lower end of the first semi-ring is fixedly installed on the inner bottom wall of the box 100. The second support semi-ring 242 is rotatably installed on the first support semi-ring 241. The outer ring wall of the first support semi-ring 241 contacts the inner ring wall of the second support semi-ring 242. A slider 244 is fixedly connected to the inner ring wall of the second support semi-ring 242. The outer ring wall of the first support semi-ring 241 has a groove 243 for the slider 244 to slide in. The slider 244 is slidably installed in the groove 243. A limiting protrusion extends from the bottom wall of the slider 244, and an arc groove is provided on the bottom wall of the groove 243 for the protrusion to slide in, so that the slider 244 cannot leave the first support semi-ring 241. The second support semi-ring 242 is close to the box door for easy opening. The second support semi-ring 242 can rotate to expose the wires, and also facilitates the filling of the filling particles into the installation cylinder 500.

[0050] The implementation principle of the anti-electric shock safety energy metering box in this application embodiment is as follows:

[0051] The insulated mounting frame 200 consists of a base plate 210, a top plate 220, and a heat sink 230. All components are made of insulating material to ensure electrical isolation between the inside of the electricity metering box and the external environment. The heat sink 230 consists of at least two rows of mounting rods 231, with multiple spherical structures 232 connected in series on each row of rods 231. These spherical structures 232 not only increase the heat dissipation area but also act as a barrier between the components and the box 100 through mutual contact. The support rods 240 not only support the entire insulated mounting frame 200 but also provide a passage for wires to pass through and, in conjunction with the sealing components, provide dust and insect protection, thus improving the overall safety performance of the electricity metering box.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
