Description

Technical Field

[0001] The invention relates to the technical field of electrical equipment, in particular to a modular wiring-free metering box. Background Art

[0002] The meter box is a set of metering instruments and auxiliary equipment necessary for measuring electric energy, including electric energy meters, voltage and current transformers and their secondary circuits, electric energy metering panels, cabinets, boxes, etc.

[0003] At present, in the prior art, electrical equipment installed in a meter box is basically assembled by wire connection when making circuit connections. For example, a Chinese patent with application number 202410109226.9 discloses an outdoor modular anti-theft electricity meter box, including an electricity box body, an electricity meter is arranged in the electricity box body, the top and bottom of the electricity meter are provided with terminal plates, the rear surface of the electricity meter is fixedly connected to a pre-positioning column, and the electricity meter is movably arranged in the electricity box body through the pre-positioning column.

[0004] The technical solution in the above-mentioned patent document achieves the fixation of the electric energy meter by clamping and limiting. However, each electric energy meter is still connected to the circuit by wire connection. The meter box is generally equipped with multiple electrical devices. When each electrical device is connected by wire, the connection between the wire and the port of the electrical device is not only cumbersome to assemble, affecting the efficiency of assembly and maintenance, but also has certain construction requirements when connecting the wire to the port of each electrical device, which is demanding for the staff. The arrangement of a large number of wires in the meter box will cause the wiring to be messy, affecting the use safety of each electrical device in the meter box and further increasing the assembly and maintenance burden of the staff. The existing meter box basically uses natural heat dissipation through ventilation holes for heat dissipation. Its heat dissipation effect is limited and the heat dissipation effect cannot be adjusted according to the change of the internal temperature of the meter box. If the internal temperature of the meter box is too high, relying solely on the natural heat dissipation of the ventilation holes cannot guarantee the heat dissipation requirements of the meter box, which can easily cause a series of adverse problems, causing damage to the equipment and affecting the use of electricity. If the internal temperature of the meter box is too low, since the use of electrical equipment has certain temperature requirements, the low temperature will accelerate the loss of electrical equipment and shorten its service life.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. By setting up an intermediate frame, the assembly of various electrical equipment is realized to form a metering module, and a copper bus is integrated on the loading plate of the intermediate frame to replace the circuit composed of wires, and the main switch body and various air switches are pre-assembled on the loading plate. Then, with the cooperation of the assembly components, it is only necessary to slide the electric energy meter body to be assembled downward to realize the connection between the electric energy meter body and the circuit, and then use screws to realize the assembly and fixation of the electric energy meter body on the loading plate. When the electric energy meter body is slid into the assembly component, the connection end is connected to the port on the electric energy meter body, avoiding the assembly and setting of the wires, thereby not only improving its assembly safety, reducing the skill requirements for the staff, and reducing its loading and maintenance burden, but also improving the neatness inside the box.

[0029] 2. By arranging heat dissipation components on the inner walls on both sides of the shell, and setting a driving mechanism on the bottom inner wall of the shell, an air-cooling structure is formed together with the auxiliary parts and corresponding grid plates in the box. The temperature sensor body monitors the temperature of the inner wall of the box and transmits the monitoring information to the controller body. The controller body turns on the bidirectional electric push rod in the driving mechanism according to the received stable information. When the bidirectional electric push rod is extended, it drives the corresponding splicing parts to move synchronously. When the splicing parts move, the connecting rod and the corresponding auxiliary parts cooperate to realize the lifting and lowering adjustment of the corresponding grid plate, thereby realizing the size adjustment of the air inlet.

[0030] 3. When the temperature inside the box is too high, the controller body starts the two-way electric push rod and moves it to the maximum mileage. At this time, each splicing part uses the corresponding auxiliary parts to realize the corresponding grid plate to the maximum mileage during the movement, and the air inlet is opened to the maximum state. When the splicing part moves to the maximum mileage, it is plugged into the corresponding connecting ring to limit the position. Then the controller body starts the dual-axis motor to drive the movement of the rotating shaft. When the rotating shaft rotates, it passes through the plug-in limit of the sliding sleeve in the splicing part and the connecting ring, thereby synchronously driving the movement of the corresponding gear chain part, thereby driving the fan blades in the corresponding heat dissipation component to rotate and blow air, achieving the effect of air cooling and heat dissipation. The operation of the dual-axis motor causes the cleaning part threaded thereon to perform reciprocating activities, and synchronously realizes the cleaning of the ventilation slots.

[0031] 4. When the temperature inside the box is normal, the controller body turns on the two-way electric push rod to retract a distance. The corresponding splicing parts will not be plugged into the corresponding connecting rings for a limit position after the activity, so that the air-cooling heat dissipation effect will not be achieved. However, after the splicing parts are active, the connecting rods loaded thereon realize the lifting and lowering adjustment of the corresponding grid plates through the cooperation with the corresponding auxiliary parts, thereby realizing the size adjustment of the air inlet. At this time, the air inlet is in a semi-open state, and the heat dissipation effect inside the box is guaranteed by means of natural air cooling. The continuous operation of the rotating shaft driven by the dual-axis motor will make the cleaning parts threaded on it to be reciprocated and adjusted to maintain the cleaning effect of the ventilation slots.

[0032] 5. When the temperature inside the box is too low, the controller body turns on the two-way electric push rod to retract to the initial state, and ensures the continuous operation of the dual-axis motor to maintain the cleaning effect of the cleaning parts on the ventilation slots. The two-way electric push rod drives the corresponding splicing parts to move. The splicing parts will not be plugged into the corresponding connecting rings for limit after the movement, so that the air-cooled heat dissipation effect will not be achieved. However, after the splicing parts are moved, the connecting rods loaded on them can realize the lifting and lowering adjustment of the corresponding grid plates through the cooperation with the corresponding auxiliary parts, thereby realizing the size adjustment of the air inlet. At this time, except for the topmost air inlet, the other air inlets are in a covered state, which reduces the heat dissipation effect of the box, realizes the utilization of the heat generated by the electrical equipment during operation, avoids the electrical equipment from running for a long time under low temperature conditions, and ensures its service life.

The top of the connecting rod 32 is fixedly connected to the corresponding grid plate 17 via screws. The bottom end of the connecting rod 32 is located below the bottom of the side frame 31 and contacts the corresponding fixing plate 163. As the fixing plate 163 rises, it simultaneously pushes up the connecting rod 32 on top.

[0059] A locating ring is fixedly connected to the outer shell of the connecting rod 32. A return spring is sleeved between the locating ring and the side frame 31. The return spring on the connecting rod 32 ensures that the connecting rod 32 moves downward synchronously with the downward movement of the fixing plate 163. The contact design between the connecting rod 32 and the fixing plate 163 facilitates disassembly and maintenance of the heat dissipation assembly 3.

[0060] A circular hole is provided on the side wall of the side frame 31, in which a transmission shaft is rotatably connected, and a fan blade is installed at the inner end of the transmission shaft.

The bottom end of the driven rack 285 extends through the bottom wall of the notch and is fixedly connected to the corresponding port plate 282. A driving rack 286 meshes with the rear of the gear 284. The top of the driving rack 286 is fixedly connected to a support plate that contacts the meter body 27. The bottom end of the driving rack 286 also extends through the bottom wall of the notch and is mounted with a spring-loaded telescopic rod 287. The bottom of the spring-loaded telescopic rod 287 is equipped with an ear plate, the side wall of which is integrally mounted on the corresponding inner wall of the cavity. During downward assembly of the meter body 27, its bottom first contacts the support plate. Then, as the meter body 27 continues to move downward, the driving rack 286 moves downward, compressing the spring-loaded telescopic rod 287. During the downward movement, the active rack 286 engages with the gear 284 to move, thereby driving the driven rack 285 engaged with the gear 284 to move upward, thereby enabling the port plate 282 to drive the connecting terminal 283 to move upward and extend, thereby completing the plug-in assembly of the connecting terminal 283 and the wiring port on the electricity meter body 27.

[0073] The working principle of the present invention is: when the product is assembled, the box body 1 is first fixed to the wall by expansion bolts, and then the cabinet door 15 on the box body 1 is opened to facilitate the staff to assemble the electric energy meter body 27 in the metering module 2.

[0074] Select a suitable electricity meter body 27 and place it in correspondence with the assembly components 28 distributed on the middle frame. The back of the electricity meter body 27 contacts the loading plate 24 in the middle frame and is located above the corresponding assembly component 28. Then, the electricity meter body 27 to be assembled is slid downward for adjustment. When the electricity meter body 27 slides down, its bottom end first contacts the support plate of the corresponding assembly component 28. The electricity meter body 27 then continues to move downward, exerting pressure on the support plate in contact with it. When the support plate is subjected to force, the corresponding active rack 286 moves downward, thereby compressing the corresponding spring telescopic rod 287. Due to the meshing transmission between the active rack 286 and the gear 284, when the active rack 286 moves downward, the gear 284 meshing with it rotates. The gear 284 and the driven rack 285 are also meshingly transmitted, and when the gear 284 moves, the corresponding driven rack 285 moves upward. The driven rack 285 drives the port plate 282 to move synchronously during the upward movement, and the movement of the port plate 282 causes the multiple connection terminals 283 arranged thereon to extend from the corresponding channels.

[0075] When the meter body 27 slides downward to its maximum range, the connection terminals 283, driven by the port plate 282, are inserted into corresponding connection ports on the meter body 27, connecting the meter body 27 to the circuit. After the circuit connection is complete, the meter body 27 is secured to the loading plate 24 with screws. This repetitive process allows for the convenient assembly of multiple meter bodies 27.

[0076] When the product is assembled and used, if the temperature sensor body 5 installed inside the box body 1 transmits a signal to the controller body 6 indicating that the temperature is too high, the controller body 6 activates the bidirectional electric push rod 48 in the drive mechanism 4, causing both output ends of the two sides to move to the maximum range. As the output ends of the bidirectional electric push rod 48 move, the corresponding vertical plate 44 in the drive mechanism 4 moves and adjusts to the maximum range.

[0077] As the vertical plate 44 moves, the sleeves 43, to which it is movably connected, move synchronously. Consequently, the corresponding sleeves 43 on each shaft 42 slide to their maximum displacement along with the movement of the vertical plate 44. At this point, the sleeves 43 engage and limit the corresponding connecting rings 47, completing assembly with the corresponding bearings. When the vertical plate 44 slides to its maximum displacement, the adjustment rod 46 mounted on it moves synchronously. The adjustment rod 46 moves within the inclined slot of the slide 161 in the corresponding auxiliary component 16, causing the slide 161 to move upward. The support rod 162 moves the corresponding fixed plate 163 upward to its maximum displacement. As the fixed plate 163 moves upward, it supports the bottom end of the connecting rod 32 in the corresponding heat sink assembly 3, compressing the return spring and causing the corresponding grille plate 17 to move to its maximum displacement, fully opening the air inlet on the side wall of the housing 11.

[0078] After the vertical plate 44 slides to the maximum mileage, the controller body 6 starts the dual-axis motor 41 to drive the rotating shaft 42 to rotate. At this time, since each sleeve 43 is respectively plugged and limited with the corresponding connecting ring 47, the rotating shaft 42 drives the sleeve 43 to move while driving the tooth chain member 45 to move. Due to the linkage effect of the tooth chain member 45, the transmission shaft in the corresponding heat dissipation component 3 rotates accordingly, and under the rotation of the fan blades, the external gas is blown into the interior of the box body 1 from the air inlet, realizing air cooling of the internal structure of the box body 1. The airflow entering the box body 1 is discharged through the ventilation slots acting as the air outlet, and the hot air in the box body 1 is brought out of the box body 1, thereby achieving efficient heat dissipation of the product.

[0079] After the dual-axis motor 41 is running, the cleaning member 49 threadedly connected thereto performs a reciprocating displacement movement, thereby cleaning each ventilation slot.

[0080] If the temperature sensor body 5 in the box body 1 detects that the temperature in the box body 1 is in a normal state. At this time, the controller body 6 starts the bidirectional electric push rod 48 to retract one mile, and then the corresponding vertical plate 44 drives the corresponding sliding sleeve 43 to retract, so that the sliding sleeve 43 and the corresponding connecting ring 47 are disengaged from the limit. At this time, the dual-axis motor 41 drives the rotating shaft 42 to perform idling activities, and the gear chain part 45 is no longer moving, so that the transmission shaft connected thereto cannot move, and the heat dissipation component 3 cancels the air cooling effect. The movement of the rotating shaft 42 can only ensure the cleaning effect of the threaded cleaning part 49 on the ventilation slot. When the vertical plate 44 retracts, the adjustment rod 46 on it moves in the inclined groove of the corresponding slide 161, causing the slide 161 to move downward. After the slide 161 moves downward, it drives the fixed plate 163 downward through the support rod 162. When the fixed plate 163 moves downward, the connecting rod 32 in the corresponding heat dissipation assembly 3 above it moves downward under the action of the return spring, thereby driving the corresponding grid plate 17 to move downward, and the grid plate 17 semi-blocks the air inlet, thereby achieving natural air cooling and heat dissipation inside the box 1.

[0081] If the temperature sensor body 5 in the box body 1 detects that the temperature inside the box body 1 is too low, the controller body 6 starts the bidirectional electric push rod 48 to retract one distance again, so that it retracts to the initial state. The bidirectional electric push rod 48 drives the corresponding sliding sleeve 43 to retract again through the corresponding vertical plate 44, so that the sliding sleeve 43 and the corresponding connecting ring 47 are separated again. At this time, the dual-axis motor 41 drives the rotating shaft 42 to perform idling movement, and the gear chain part 45 is no longer moving, thereby making the transmission shaft connected thereto unable to move, and the heat dissipation component 3 cancels the air cooling effect. The movement of the rotating shaft 42 can only ensure the cleaning effect of the threaded cleaning part 49 on the ventilation slot. When the vertical plate 44 retracts again, the adjustment rod 46 on it moves in the inclined groove of the corresponding slide 161, causing the slide 161 to move down again. After the slide 161 moves down, it drives the fixed plate 163 to move down through the support rod 162. When the fixing plate 163 moves downward, the connecting rod 32 in the corresponding heat dissipation assembly 3 above it moves downward under the action of the return spring, thereby driving the corresponding grille plate 17 to move downward again. At this time, except for the topmost air inlet which is in a semi-blocked state and shifted, the other air inlets are completely blocked by the grille plate 17, reducing the exchange channel between the internal air of the box 1 and the external air, fully utilizing the heat generated by the operation of the equipment inside the box 1, so that the interior of the box 1 reaches a suitable temperature, thereby preventing the internal structure of the box 1 from operating at a low temperature for a long time and extending the service life of the product.

[0082] When the interior of the box body 1 needs to be cooled by air, the controller body 6 needs to first pause the dual-axis motor 41 and then start the bidirectional electric push rod 48 to ensure smooth insertion between the sliding sleeve 43 and the corresponding connecting ring 47.

Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
