Technical Field

[0001] This invention relates to the field of cable management devices, and in particular to a centralized cable routing and management mechanism for an electricity metering box and its usage method. Background Technology

[0002] An electricity metering box is a closed or semi-closed device specifically designed for the safe and accurate measurement of electrical energy. It integrates core metering components such as electricity meters, transformers, and terminals, as well as related auxiliary equipment. Through a reasonable structural layout and protective design, it provides a stable installation environment and reliable electrical connection for these components. It is widely used in electricity metering scenarios for various power users and power supply lines.

[0003] The multiple incoming, outgoing, and meter connection wires inside the electricity metering box are often randomly intertwined, which not only seriously affects the aesthetics and does not meet the requirements of standardized operation, but also causes a series of safety hazards and maintenance problems, including poor heat dissipation and local overheating caused by the tight stacking of cables, accelerated insulation aging and even fire risk, mechanical damage and short circuit leakage hazards caused by the mutual squeezing and pulling of cables.

[0004] Therefore, a cable management mechanism for power metering boxes and its usage method are proposed to solve the above-mentioned problems. Summary of the Invention

[0005] To achieve the above objectives, the present invention provides the following technical solution: a centralized cable routing and organizing mechanism for an electricity metering box, comprising a box body, wherein a cable routing mechanism is provided inside the box body, and a cooling mechanism is provided on the cable routing mechanism; The wiring mechanism includes a mounting plate, a first mounting block and a second mounting block are fixedly connected to the top of the mounting plate, a fixed cylinder is fixedly connected to one side of the first mounting block, a threaded rod is rotatably connected between the first mounting block and the second mounting block, a threaded block is fixedly connected to the outer side of the threaded rod, a sliding rod is slidably connected inside the fixed cylinder, an adjusting block is fixedly connected to the side of the sliding rod away from the fixed cylinder, a worm gear is fixedly connected to the outer side of the threaded rod, a worm is rotatably connected to the top of the mounting plate, and a wire frame is fixedly connected to the top of the mounting plate.

[0006] Preferably, the rear side of the inner wall of the enclosure is fixedly connected to the electricity meter body, the top wall of the enclosure has at least three inlet holes, the bottom wall of the enclosure has at least three outlet holes, a protective coil is installed in each inlet hole and outlet hole, and heat dissipation strip holes are provided at the top and bottom of the enclosure.

[0007] Preferably, the mounting plate is installed on the inner bottom wall of the housing by bolts. The number of the first mounting block and the second mounting block is not less than three and they are symmetrically distributed front and back. The first mounting block and the second mounting block correspond one-to-one with the cable outlet hole. The first mounting block has a first cable management hole inside, and the second mounting block has a second cable management hole inside.

[0008] Preferably, the threaded rod passes through the fixed cylinder on the side away from the second mounting block and is rotatably connected to the first mounting block. The fixed cylinder is designed in the shape of a frustum. The interior of the fixed cylinder has a groove that matches the movement trajectory of the sliding rod, and the interior of the fixed cylinder has an clearance hole that matches the movement trajectory of the adjusting block.

[0009] Preferably, the number of the adjusting blocks is four and they are centrally symmetrically distributed inside the fixed cylinder. The threaded block is designed in the shape of a frustum and fits against the inner wall of the four adjusting blocks.

[0010] Preferably, the worm gear is located between the fixed cylinder and the second mounting block, the worm gear meshes with the worm, the wire frame is located directly below the fixed cylinder, and the number of wire frames is not less than three, and they are respectively on the same axis as the first wire guide hole and the second wire guide hole.

[0011] Preferably, the cooling mechanism includes a mounting frame, a drive motor is fixedly connected inside the mounting frame, a fan blade is detachably mounted on the output shaft of the drive motor, a controller is fixedly connected to the outside of the housing, and a conductive rubber strip is fixedly connected to the outside of the adjusting block.

[0012] Preferably, the mounting frame is detachably connected to the inner bottom wall of the housing and is located between the heat dissipation strip hole and the wiring mechanism. The number of mounting frames is two and they are symmetrically distributed from left to right.

[0013] On the other hand, this application also proposes a method for using a centralized cable routing and organizing mechanism for an electricity metering box, including the following steps: S1, installing the cable routing mechanism by bolting the entire cable routing mechanism onto the inner bottom wall of the box; S2. Adjust the cable routing mechanism and adjust the position of the adjusting block according to the cable specifications.

[0014] S3. Cable connection: Pull the cable of the external power grid into the box 1 through the inlet hole, pass through the energy meter and out through the first cable management hole, wrap around the surface of the regulating block, then pass through the conductor frame and the second cable management hole in sequence, and finally out through the outlet hole. S4. Internal temperature monitoring and control of the enclosure: The temperature of the cable is monitored by a cooling mechanism and cooled when necessary.

[0015] In summary, the present invention provides a cable consolidation and management mechanism for electricity metering boxes and its usage method, which has the following beneficial effects: 1. The cable consolidation and management mechanism for this power metering box and its usage method utilize a worm gear driven by a worm wheel and a threaded rod for precision transmission. This drives the axial movement of the frustum-shaped threaded block, simultaneously propelling four centrally symmetrical adjusting blocks radially along the sliding grooves within the fixed cylinder. This achieves stepless adjustment of the cable channel diameter. This design allows the mechanism to perfectly adapt to cables of different diameters, providing stable support to prevent loosening while avoiding damage to the insulation layer caused by mechanical stress from excessive clamping. Combined with the cable management holes on the first and second mounting blocks and the straight alignment path formed by the conductor frame facing the outlet, this ensures that the cables are neatly arranged from the inlet to the outlet, reducing bending stress and mutual interference.

[0016] 2. The cable consolidation and management mechanism and its usage method used in this power metering box monitor the surface temperature of the cables in real time through conductive rubber strips tightly attached to the cable surface and transmit the signal to the controller. When the temperature exceeds a preset threshold, the controller immediately starts two symmetrically arranged drive motors, which drive the fan blades to rotate at high speed, forming a forced convection airflow that draws in cool air from the bottom of the box, flows through the cable consolidation area, and is discharged from the top of the box. This directly and efficiently dissipates heat from the cable accumulation area. Once the temperature drops, the system automatically shuts off the fan. Through closed-loop control with real-time temperature feedback, the overall temperature rise inside the box is greatly reduced, effectively delaying cable insulation aging and preventing fire hazards.

[0017] 3. The cable consolidation and management mechanism for the power metering box and its usage method: The entire consolidation mechanism is fixed to the bottom wall of the box by mounting plate bolts, realizing modular quick installation and disassembly. The fan blades adopt a detachable design, which is convenient for cleaning and replacement. Both the inlet and outlet holes are equipped with protective coils, which take into account both protection and sealing. This makes the mechanism not only highly efficient in wiring and good in heat dissipation, but also has excellent maintainability and adaptability. Attached Figure Description

[0020] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Example

[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, a cable consolidation and management mechanism for an electricity metering box includes a box body 1, a cable routing mechanism 2 is provided inside the box body 1, and a cooling mechanism 3 is provided on the cable routing mechanism 2. The wiring mechanism 2 includes a mounting plate 201. A first mounting block 202 and a second mounting block 203 are fixedly connected to the top of the mounting plate 201. A fixed cylinder 204 is fixedly connected to one side of the first mounting block 202. A threaded rod 205 is rotatably connected between the first mounting block 202 and the second mounting block 203. A threaded block 206 is fixedly connected to the outside of the threaded rod 205. A sliding rod 207 is slidably connected inside the fixed cylinder 204. An adjusting block 208 is fixedly connected to the side of the sliding rod 207 away from the fixed cylinder 204. A worm gear 209 is fixedly connected to the outside of the threaded rod 205. A worm gear 210 is rotatably connected to the top of the mounting plate 201. A wire frame 211 is fixedly connected to the top of the mounting plate 201.

[0022] like Figure 1 , Figure 2 and Figure 3As shown, the rear inner wall of the box 1 is fixedly connected to the electricity meter body. The top inner wall of the box 1 has no fewer than three inlet holes 101, which allow for centralized cable entry, facilitate standardized cable entry paths, and reduce clutter inside the box. The bottom inner wall of the box 1 has no fewer than three outlet holes 102, which allow cables to be led out in an orderly manner, avoid cable crossing and tangling, and facilitate later maintenance. Both the inlet holes 101 and the outlet holes 102 are equipped with protective coils, which protect the cable sheath from scratches by the holes and also serve as dustproof and waterproof. The top and bottom of the box 1 are provided with heat dissipation strip holes, which form natural ventilation channels and assist the cooling mechanism 3 in improving the overall heat dissipation efficiency.

[0023] like Figure 3 and Figure 4 As shown, the mounting plate 201 is installed on the inner bottom wall of the housing 1 by bolts. The bolt connection makes the mounting plate 201 securely installed and removable, which facilitates the maintenance and replacement of the entire cable routing mechanism 2. There are no fewer than three first mounting blocks 202 and two mounting blocks 203, which are symmetrically distributed front and back. Multiple sets of symmetrically distributed first mounting blocks 202 and second mounting blocks 203 support the simultaneous arrangement of multiple cables, improving the cabling efficiency. The first mounting blocks 202 and second mounting blocks 203 correspond one-to-one with the cable outlet holes 102. The one-to-one correspondence design ensures that the path of each cable from the inlet to the outlet is clear and avoids cross interference. The first mounting block 202 has a first cable management hole inside, and the second mounting block 203 has a second cable management hole inside. The first cable management hole and the second cable management hole perform preliminary positioning and separation of the cables, improving the neatness of the cable routing.

[0024] like Figure 4 and Figure 5 As shown, the threaded rod 205 passes through the fixed cylinder 204 on the side away from the second mounting block 203 and is rotatably connected to the first mounting block 202. Both ends of the threaded rod 205 are supported, which enhances the transmission stability and prevents jamming during adjustment. The fixed cylinder 204 is designed in the shape of a frustum. The frustum-shaped fixed cylinder 204 provides a guide slope for the adjusting block 208, so that it can expand or contract smoothly during movement. The interior of the fixed cylinder 204 is provided with a groove that matches the movement trajectory of the sliding rod 207. The groove guides the sliding rod 207 to move along a predetermined path, ensuring that the movement trajectory of the adjusting block 208 is accurate. The interior of the fixed cylinder 204 is provided with a clearance hole that matches the movement trajectory of the adjusting block 208. The clearance hole provides movement space for the adjusting block 208 and prevents it from interfering with the inner wall of the fixed cylinder 204 during adjustment.

[0025] like Figure 6As shown, there are four adjusting blocks 208, which are centrally symmetrically distributed inside the fixed cylinder 204. The four symmetrically distributed adjusting blocks 208 can evenly support the cable from multiple directions, avoiding excessive force on a single point. The threaded block 206 is designed in the shape of a frustum and fits against the inner wall of the four adjusting blocks 208. When the frustum-shaped threaded block 206 moves axially, it pushes the adjusting blocks 208 to move radially, realizing the synchronous adjustment of the clamping diameter.

[0026] like Figure 3 , Figure 4 and Figure 5 As shown, the worm gear 209 is located between the fixed cylinder 204 and the second mounting block 203. The worm gear 209 meshes with the worm 210. The meshing of the worm gear 209 and the worm 210 provides reliable transmission and self-locking, ensuring that the position is fixed and does not loosen after adjustment. The wire frame 211 is located directly below the fixed cylinder 204 and faces the outlet of the fixed cylinder 204, ensuring that the cable can smoothly enter the next guiding link after adjustment. There are no less than three wire frames 211, and they are respectively on the same axis as the first cable management hole and the second cable management hole. The axis alignment design ensures that the cable path from the inlet to the outlet is straight, reducing bending stress.

[0027] like Figure 3 and Figure 7 As shown, the cooling mechanism 3 includes a mounting frame 301, inside which a drive motor 302 is fixedly connected. The mounting frame 301 provides protection and fixation for the drive motor 302. The drive motor 302 serves as the active cooling power source. The output shaft of the drive motor 302 is detachably mounted with fan blades 303. The fan blades 303 are detachable for easy cleaning or replacement and convenient maintenance. A controller 304 is fixedly connected to the outside of the housing 1. The controller 304 realizes intelligent control of the entire cooling system and can automatically start and stop the fan according to the temperature. A conductive rubber strip 305 is fixedly connected to the outside of the adjusting block 208. The conductive rubber strip 305 directly contacts the electric current. The cable surface is monitored for temperature changes in real time, providing signal input for intelligent heat dissipation. The controller 304 monitors the cable sheath temperature in real time based on the conductive rubber strip 305 installed on the outside of the regulating block 208. When the detected temperature exceeds the preset threshold, the controller 304 automatically starts the drive motor 302. The drive motor 302 drives the fan blades 303, which are detachably connected to its output shaft, to rotate, forcing airflow to cool the cable and the environment inside the box. When the temperature drops below the safe range, the controller 304 automatically shuts off the drive motor 302, causing the fan blades 303 to stop working, thereby realizing intelligent and energy-saving start-stop control based on the actual temperature of the cable.

[0028] like Figure 3As shown, the mounting frame 301 is detachably connected to the inner bottom wall of the housing 1 and is located between the heat dissipation strip hole and the wiring mechanism 2, so that the fan blade 303 can directly blow air onto the wiring area, which is highly targeted in heat dissipation. There are two mounting frames 301 and they are symmetrically distributed from left to right. The symmetrical layout of the double fan blades 303 enhances the uniformity of heat dissipation and avoids local overheating dead corners in the housing 1. Example

[0029] like Figure 8 As shown, this application also proposes a method for using a centralized cable routing and organizing mechanism for an electricity metering box, including the following steps: S1, installing the cable routing mechanism 2, and installing the entire cable routing mechanism 2 on the inner bottom wall of the box body 1 by bolts; S2. Adjust the cable routing mechanism 2 and adjust the position of the adjusting block 208 according to the cable specifications.

[0030] S3. Cable connection: Pull the cable of the external power grid into the box 1 through the inlet hole 101, pass through the energy meter and out through the first cable management hole, and wrap around the surface of the adjusting block 208, then pass through the conductor frame 211 and the second cable management hole in sequence, and finally out through the outlet hole 102. S4. Temperature monitoring and control inside the enclosure 1: The temperature of the cable is monitored by the cooling mechanism 4 and cooled when necessary.

[0031] In use, firstly, the mounting plate 201 is securely installed on the inner bottom wall of the housing 1 with bolts, completing the initial fixation of the cable routing mechanism 2. Then, the clamping mechanism is adjusted according to the specific specifications of the cables to be laid: by rotating the worm gear 210, the worm wheel 209 meshing with it is driven to rotate. The worm wheel 209 drives the threaded rod 205 to rotate between the first mounting block 202 and the second mounting block 203, causing the threaded block 206 fixedly connected to the outside of the threaded rod 205 to produce axial displacement. Because the threaded block 206 has a frustum-shaped design and is symmetrically distributed with four centers, the clamping mechanism... The inner walls of the section 208 are fitted together, and its axial movement will push each adjusting block 208 to move radially synchronously along the sliding groove opened in the fixed cylinder 204, thereby adjusting the diameter of the cable channel formed by the adjusting blocks 208. This ensures that it can provide sufficient support for cables of different specifications to prevent the cables from loosening, while avoiding mechanical stress caused by excessive winding, which could damage the cable insulation layer. When laying the cable, the external cable is introduced through the inlet hole 101 opened at the top of the box 1, passes through the protective coil, connects to the energy meter, and then exits through the first cable management hole of the first mounting block 202. The cable then winds around the adjusted surface of the regulating block 208, gaining effective support and fixation, before being guided downwards into the conductor frame 211 located directly below the fixing cylinder 204 for proper routing. Finally, it passes through the second cable management hole of the second mounting block 203 and is led out to the user's load via the bottom cable outlet hole 102. During operation, the conductive rubber strip 305, tightly attached to the cable surface, continuously monitors its surface temperature and transmits the signal in real time to the controller 304 on the outside of the enclosure 1. When the monitored temperature exceeds a preset safety threshold, the controller 304 immediately activates the circuit installed in the enclosure. Two drive motors 302 are symmetrically distributed on the bottom wall of the inner body 1. The drive motors 302 drive the detachable fan blades 303 to rotate at high speed, drawing in cold air from the heat dissipation vents at the bottom of the housing 1. The airflow blows directly towards the cable routing mechanism 2 area and carries heat out through the heat dissipation vents at the top, achieving targeted forced convection cooling of the cables and the environment inside the housing 1. When the temperature drops below the safe range, the controller 304 automatically shuts off the drive motors 302, causing the fan blades 303 to stop running. This ensures effective heat dissipation while achieving energy saving, consumption reduction, and intelligent control.
