Description
Technical Field
[0001] The present application relates to the technical field of electric energy metering boxes, and in particular to an electric energy metering box that is safe and can prevent electric shock. Background Art
[0002] The electric energy meter box is a set of measuring instruments and auxiliary equipment necessary for measuring electric energy, which mainly includes electric energy meter, voltage and current transformer and its secondary circuit, electric energy metering panel, cabinet, box, etc.
[0003] Existing metal energy meter boxes are generally made of metal to adapt to different environments. However, appropriate insulation protection should be provided within the box to prevent electric shock. As described in patent application number CN202320227596.3, an insulating protective shell is installed within the box and fixedly mounted within the box. Electronic components are installed within the insulating protective shell, and the mounting position of the electronic components is difficult to adjust. When the electronic components within the energy meter box are in operation, they emit heat. When the box dissipates heat, the insulating protective shell provides a certain barrier effect, and the heat dissipation effect of the box needs to be improved. Summary of the Invention
[0004] In order to facilitate heat dissipation of electronic components in the electric energy meter box and to flexibly adjust their positions, the present application provides an electric shock-proof safety electric energy meter box.
[0005] This application provides an anti-electric shock safety electric energy metering box, which adopts the following technical solutions:
[0006] An anti-electric shock safety electric energy metering box comprises a box body, an insulating mounting frame installed in the box body, the mounting frame comprising a bottom plate and a top plate, a heat sink mounted between the bottom plate and the top plate, the heat sink comprising at least two rows of mounting rods, a plurality of mounting rods in a row of mounting rods being spaced apart, spherical structures being connected in series to the mounting rods, adjacent two spherical structures on the same mounting rod being tangent to each other, spherical structures between adjacent two mounting rods in the same row of mounting rods being tangent to each other, and spherical centers of adjacent two spherical structures in two adjacent rows of mounting rods being at different heights; a mounting seat being mounted on the heat sink; a spacing being left between the bottom plate, the top plate and the heat sink and the inner wall of the box body, a support rod being connected to the bottom plate and the inner bottom wall of the box body; a heat sink being provided on one side of the box body close to the heat sink;

[0009] The mounting seat is mounted on the mounting rods in the same row. The lower ends of the mounting rods in the same row are connected with linkage rods. The linkage rods are in sliding contact with the base plate. The linkage rods slide toward or away from the mounting rods in other rows.
[0010] By adopting the above technical solution, the meter box isolates the internal electronic components from the box body through the insulating mounting frame, effectively preventing the risk of electric shock, and at the same time using the spherical structure on the heat dissipation rack to increase the heat dissipation area and improve the heat dissipation efficiency. Adjacent spherical structures are in a tangent state and the height positions of the centers of the spheres in two adjacent rows are different. The side walls of the box body are provided with heat dissipation grooves to facilitate heat exchange between the air inside the box and the outside air. If wind or dust enters the box body through the heat dissipation grooves of the box body, the spherical structures on the two rows of mounting rods are tangent, and the spherical structures are staggered with each other. The heat dissipation rack can not only dissipate heat for the electronic components on the mounting seat, but also have a barrier effect. In addition, the spherical structure can also slide 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. Installation The seat provides a stable installation foundation through the fixed connection between the mounting ring and the mounting plate; the design of the perforation and the give way groove enables the mounting seat to fit tightly against the spherical structure on the heat sink, ensuring the stable installation of the connector; 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 to be adjusted as needed to adapt to different working environments or heat dissipation requirements, and when the spherical structures of the two rows of mounting rods are tangent, the two rows of spherical structures limit each other, so that the mounting seat is stably installed on the heat sink. When the linkage rod carries one row of mounting rods away from the other row of mounting rods, the abutment block is rotated to leave the spherical structure, the spherical structure can be moved, and the installation position of the mounting seat can be adjusted, so that the electronic components can be installed on the insulating mounting frame, which is convenient for heat dissipation and can flexibly adjust its own position.
[0011] Optionally, a groove is formed on a side wall of the mounting plate close to the mounting ring.
[0012] 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 seat.
[0013] Optionally, a first wiring port is provided on the bottom plate, a second wiring port is provided on the bottom wall of the box body, 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, and 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 body at the second wiring port.
[0014] By adopting the above technical solution, not only a passage for the wires to pass through is provided, but also the intrusion of external dust and moisture is prevented by the blocking component.
[0015] Optionally, the support rod includes a first support half ring and a second support half ring, the first support half ring is fixedly mounted on the base plate, and the second support half ring is rotatably mounted on the first support half ring.
[0016] By adopting the above technical solution, the first supporting half ring and the second supporting half ring cooperate to allow the wires to be exposed or wrapped.
[0017] Optionally, the blocking assembly includes filling particles and a mounting tube for containing the filling particles, the outer wall of the mounting tube is a variable diameter structure, and the end of the mounting tube with a larger outer diameter is fixedly connected to the box body.
[0018] By adopting the above technical solution, filling particles can be filled in the installation tube, and the wires can be led out through the installation tube; this design not only ensures the safe leading out of the wires, but also prevents the intrusion of external dust and moisture.

DETAILED DESCRIPTION
[0033] The following is combined with Figure 1 -Attached Figure 9 This application is described in further detail.
[0034] The embodiment of the present application discloses an anti-electric shock safety electric energy meter box. Figure 1 The anti-electric shock safety electric energy meter box includes a box body 100, an insulating mounting frame 200 installed in the box body 100, the mounting frame 200 includes a bottom plate 210 and a top plate 220, a heat sink 230 installed between the bottom plate 210 and the top plate 220, and a mounting base 300 for mounting electronic components is installed on the heat sink 230. There is a gap between the bottom plate 210, the top plate 220, the heat sink 230 and the inner wall of the box body 100. The bottom plate 210 and the bottom wall of the box body 100 are connected by support rods 240. There are multiple support rods 240, so that the mounting frame 200 can be stably installed in the box body 100. When the electronic components are installed on the heat sink 230 through the mounting base 300, the heat sink 230 can achieve a good heat dissipation effect when the electronic components are working.
[0035] Reference Figure 2 and Figure 3The heat dissipation rack 230 includes at least two rows of mounting rods 231, and the embodiment of the present application preferably has two rows of mounting rods 231. The multiple mounting rods 231 in one row of mounting rods 231 are spaced apart along the length direction of the base plate 210, and the adjacent two mounting rods 231 in the two rows of mounting rods 231 are staggered with each other. A plurality of spherical structures 232 are connected in series on one mounting rod 231, and the spherical structures 232 have the same outer diameter. The adjacent two spherical structures 232 in the same mounting rod 231 are tangent to each other, and the spherical structures 232 of the adjacent two mounting rods 231 in one row of mounting rods 231 are tangent to each other, and the centers of the adjacent two spherical structures 232 in the adjacent two mounting rods 231 are located at the same height. In order to make the height positions of the centers of the adjacent spherical structures 232 in the two rows of mounting rods 231 different, the starting installation positions of the spherical structures 232 of the adjacent two mounting rods 231 in the two adjacent rows of mounting rods 231 are different. A pad 233 is connected in series to the lower end of one row of mounting rods 231. The pad 233 contacts the first spherical structure 232 at the lower end of the mounting rod 231. A heat dissipation slot 110 is provided on the side wall of the housing 100. The heat dissipation slot 110 is adjacent to the heat dissipation rack 230. If wind or dust enters the housing 100 through the heat dissipation slot 110, the spherical structures 232 on the two rows of mounting rods 231 will be staggered when tangent to each other, allowing the electric meter to be installed on the heat dissipation rack 230. The heat dissipation rack 230 not only provides a heat dissipation effect but also has a barrier effect.
[0036] Reference Figure 2 and Figure 3 The lower ends of one row of mounting rods 231 are connected to linkage rods 235. The linkage rods 235 are in sliding contact with the base plate 210, and the linkage rods 235 can slide toward or away from the mounting rods 231 in other rows. In this embodiment of the present application, the row of mounting rods 231 near the mounting base 300 is slidably mounted on the base plate 210. The lower surface of the top plate 220 is provided with a recess 221. After the upper ends of the mounting rods 231 extend into the recess 221, the lower ends of the mounting rods 231 are fixedly connected to the linkage rods 235. When the linkage rods 235 slide, the upper end surfaces of the mounting rods 231 slide in contact with the bottom wall of the recess 221. The upper surface of the base plate 210 is provided with a receiving groove 212, and the linkage rods 235 are located within the receiving groove 212. A guide rod 211 is passed through the base plate 210, and the guide rod 211 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 so that the linkage rod 235 can be stably slidably installed in the receiving groove 212 .
[0037] Reference Figure 3The upper end of the mounting rod 231 is provided with a pressing block 234, which is threadedly connected to the mounting rod 231. The pressing block 234 contacts the spherical structure 232 at the upper end of the mounting rod 231, so that the spherical structure 232 is restrained. 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.
[0038] Reference Figure 4 When the linkage rod 235 moves the spherical structures 232 of one row of mounting rods 231 away from the spherical structures 232 of another row of mounting rods 231 , the pressing block 234 is rotated away from the spherical structures 232 , so that the spherical structures 232 can slide up and down.
[0039] Reference Figure 5 and Figure 6 The mounting base 300 includes a mounting ring 310 and a mounting plate 320, and the mounting plate 320 is fixedly connected to the outer wall of the mounting ring 310. The mounting ring 310 is provided with 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 installed on the heat dissipation frame 230, the mounting rod 231 passes through the mounting ring 310, and a mounting ring 310 is installed between the two spherical structures 232. The two spherical structures 232 remain in a tangent state, and the spherical structure 232 contacts the inner wall of the clearance groove 312. The spherical structure 232 has a limiting and fixing effect on the mounting ring 310, so that the mounting ring 310 is firmly installed between the two spheres. After installing the mounting base 300, the position of the mounting base 300 can also be adjusted according to the situation, thereby improving the flexibility of the position adjustment of the mounting base 300.
[0040] Reference Figure 6 The mounting ring 310 may be provided with a notch 313, through which the mounting rod 231 may be directly inserted into the mounting ring 310. To adjust the position of the mounting base 300, the linkage rod 235 and the pressing block 234 may be appropriately moved to allow the spherical structure 232 to move up and down. When the mounting ring 310 is installed, the spherical structure 232 does not need to leave the mounting rod 231, thus facilitating the connection of the mounting ring 310.
[0041] Each mounting base 300 has at least two mounting rings 310. In the embodiment of the present application, there are two mounting rings 310. When the mounting rings 310 are arranged vertically on the mounting plate 320, the two mounting rings 310 are simultaneously mounted on different spherical structures 232 of a mounting rod 231. When the mounting rings 310 are arranged horizontally on the mounting plate 320, the two mounting rings 310 are respectively mounted on different mounting rods 231. The multiple mounting rings 310 ensure a stable installation of the mounting base 300 on the heat sink 230.
[0042] The mounting plate 320 is provided with a hollow structure to facilitate heat dissipation. The hollow structure is preferably an array of threaded holes 321, and the threaded holes 321 are threadedly connected with bolts 322. The array-distributed threaded holes 321 are convenient for the installation of electrical components of different models and also help to dissipate heat. Electronic components are generally installed in the box 100 by bolts 322. For example, before the installation of the electric energy meter, the electric energy meter connector 400 is first threadedly installed. The electric energy meter connector 400 is provided with a waist-shaped hole for the bolt 322 to pass through. The bolt 322 fixes the electric energy meter connector 400 on the mounting plate 320. The mounting seat 300 and the heat dissipation frame 230 are convenient for the installation of electronic components, and also convenient for changing the installation position of electronic components according to the circuit plan, and can also achieve good heat dissipation effect.
[0043] Reference Figure 5 A groove 323 is formed on one side wall of the mounting plate 320 close to the mounting ring 310 . When the mounting seat 300 is mounted on the heat dissipation frame 230 , the spherical structure 232 contacts the inner wall of the groove 323 of the mounting plate 320 , thereby increasing the stability of the mounting plate 320 .
[0044] Reference Figure 7 A plurality of first wiring ports 213 are provided on the bottom plate 210, and a second wiring port 120 is provided on the inner bottom wall of the box body 100. 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 electric wires. A blocking assembly is provided on the outer wall of the box body 100 at the second wiring port 120. The blocking assembly includes filling particles and a mounting tube 500 for containing the filling particles. One end of the mounting tube 500 is fixedly mounted on the outer wall of the box body 100. The mounting tube 500 is a variable diameter structure. The outer diameter of the end of the mounting tube 500 close to the box body 100 is larger, and the outer diameter of the end of the mounting tube 500 away from the box body 100 is smaller. The opening with a smaller outer diameter is only for the electric wire to pass through, and the filling particles can only be filled in the mounting tube 500. The filling particles are not shown in the embodiment of the present application. The filling particles can be granular activated carbon desiccant. The activated carbon desiccant is made of high-quality sawdust, coconut shells, etc., and is processed by high-temperature activation and special pore adjustment process. It has a large specific surface area and rich medium and microporous structures. It can not only effectively remove moisture, but also absorb odors and pollutants. It is suitable for moisture-proofing and purification of electrical boxes.
[0045] Reference Figure 8 and Figure 9To facilitate the filling of filling particles, the support rod 240 includes a first support half-ring 241 and a second support half-ring 242. The upper end of the first support half-ring 241 is fixedly mounted on the bottom plate 210, and the lower end of the first half-ring is fixedly mounted on the inner bottom wall of the box body 100. The second support half-ring 242 is rotatably mounted on the first support half-ring 241. The outer ring wall of the first support half-ring 241 contacts the inner ring wall of the second support half-ring 242. A slider 244 is fixedly connected to the inner ring wall of the second support half-ring 242. The outer ring wall of the first support half-ring 241 defines a sliding groove 243 for the slider 244 to slide within. The slider 244 slides within the sliding groove 243. A limiting protrusion extends from the bottom wall of the slider 244. The bottom wall of the sliding groove 243 defines an arc groove for the protrusion to slide, preventing the slider 244 from leaving the first support half-ring 241. The second support half-ring 242 is located near the box door, making it easier for people to open it. The second supporting half ring 242 can be rotated to expose the wires, and it is also convenient to fill the filling particles into the installation cylinder 500.
[0046] The implementation principle of the anti-electric shock safety energy meter box in the embodiment of the present application is:
[0047] The insulating mounting frame 200 consists of a base plate 210, a top plate 220, and a heat sink 230. These components are all made of insulating materials to ensure electrical isolation between the interior of the energy meter box and the external environment. The heat sink 230 is composed of at least two rows of mounting rods 231, each of which is connected in series with multiple spherical structures 232. These spherical structures 232 not only increase the heat dissipation area but also, through mutual contact, provide a barrier between the components and the box 100. The support rods 240 not only support the entire insulating mounting frame 200 but also provide a passage for the wires to pass through. Together with the sealing assembly, they provide dust and insect protection, enhancing the safety of the entire energy meter box.
