[0004] The technical solution in the above patent document realizes the fixation of the electric energy meter by clamping and limiting, but each electric energy meter is still connected to the circuit by wire connection, and a plurality of electrical devices are generally arranged in the meter box. When each electrical device is connected by wire, the connection between the wire and the port of the electrical device is not only troublesome to assemble, but also affects the efficiency of assembly and maintenance. In addition, the wire has certain construction requirements when connected to the port of each electrical device, which has high requirements for the staff. The arrangement of a large number of wires in the meter box will cause the lines 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 adopts the natural heat dissipation of ventilation holes for heat dissipation, and 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, it is difficult to guarantee the heat dissipation demand inside the meter box by relying solely on the natural heat dissipation of the ventilation holes, which is easy to 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 loss of electrical equipment will be accelerated under low temperature conditions, affecting its service life.

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

[0028] 1. The assembly of various electrical equipment is realized by setting an intermediate frame 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 the wire, 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 main body of the electric energy meter to be assembled downward to realize the connection between the main body of the electric energy meter and the circuit on the intermediate frame, and then screws are used to realize the assembly and fixation of the main body of the electric energy meter on the loading plate.

[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 in combination with the auxiliary parts in the box and the corresponding grid plates. 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 two-way electric push rod in the driving mechanism through the received stable information. When the two-way 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 plates, 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 raise 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 shaft. When the 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 toothed 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 the operation of the dual-axis motor causes the cleaning part threaded thereon to reciprocate, thereby synchronously realizing 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 and retracts a mileage. The corresponding splicing parts will not be plugged into the corresponding connecting rings for 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 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, the air inlet is in a semi-open state, and the heat dissipation effect inside the box is guaranteed by natural air cooling. The continuous operation of the rotating shaft driven by the dual-axis motor will make the cleaning parts threaded on it reciprocate and adjust 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 piece on the ventilation slot. 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 position 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, so as to adjust the size 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 operation of the electrical equipment, avoids the electrical equipment from running for a long time under low temperature conditions, and ensures its service life.

[0071] A plurality of holes are linearly opened on the top shell wall of the cavity, and the top ends of the plurality of connection terminals 283 respectively pass through the corresponding holes. The setting of the holes can not only facilitate the connection terminals 283 to extend and insert into the electric energy meter body 27, but also can hide and protect the connection terminals 283 when not in use.

[0072] There are notches on both sides of the top of the bar block 281, and a gear 284 is installed on the inner wall of the side of the notch through a rotating shaft. A driven rack 285 meshing with the gear 284 is provided on the front side of the gear 284, and the bottom end of the driven rack 285 penetrates the bottom shell wall of the notch and is fixedly connected to the corresponding port plate 282. An active rack 286 meshing with the gear 284 is provided on the rear side, and the top of the active rack 286 is fixedly connected with a support plate for contacting the electric energy meter body 27, and the bottom end of the active rack 286 also penetrates the bottom shell wall of the notch, and a spring telescopic rod 287 is installed. The bottom of the spring telescopic rod 287 is provided with an ear plate, and the side wall of the ear plate is integrally arranged on the corresponding inner wall of the cavity. When the electric energy meter body 27 is assembled in a downward sliding manner, its bottom first contacts the support plate, and then the active rack 286 moves down during the continuous downward movement of the electric energy meter body 27, compressing the spring telescopic rod 287. The active rack 286 meshes with the gear 284 during the downward movement, causing the gear 284 to move, thereby driving the driven rack 285 meshing 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 electric energy 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 electric energy meter body 27 and place it on the corresponding assembly component 28 distributed on the middle frame. The back of the electric energy meter body 27 contacts the loading plate 24 in the middle frame and is located above the corresponding assembly component 28. Then the electric energy meter body 27 to be assembled is slid downward for adjustment, and the bottom end of the electric energy meter body 27 first contacts the support plate of the corresponding assembly component 28 when it moves downward. Then the electric energy meter body 27 continues to move downward, and exerts pressure on the support plate in contact with it. After the support plate is stressed, 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 meshed with it rotates. There is also meshing transmission between the gear 284 and the driven rack 285, 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 out from the corresponding channels.

[0075] When the electric energy meter body 27 slides downward to the maximum mileage, each connection terminal 283 is inserted into the corresponding connection port of the electric energy meter body 27 under the drive of the port plate 282 to achieve the connection between the electric energy meter body 27 and the circuit. After the electric energy meter body 27 is connected to the circuit, it is fixed to the loading plate 24 by screws. This cycle is repeated to achieve convenient assembly of multiple electric energy meter bodies 27.

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

[0077] When the vertical plate 44 moves, the sleeve 43 movably connected thereon moves synchronously. Then, the corresponding sleeve 43 on each rotating shaft 42 slides and moves to the maximum mileage on the corresponding rotating shaft 42 along with the movement of the vertical plate 44. At this time, the sleeve 43 and the corresponding connecting ring 47 are plugged and limited to realize the assembly with the corresponding bearing. When the vertical plate 44 slides to the maximum mileage, the adjustment rod 46 assembled thereon moves synchronously. The adjustment rod 46 moves in the inclined groove of the slide plate 161 in the corresponding auxiliary component 16, so that the slide plate 161 is adjusted to move upward. The corresponding fixed plate 163 is moved up to the maximum mileage through the support rod 162. When the fixed plate 163 moves upward, the bottom end of the connecting rod 32 in the corresponding heat dissipation component 3 is supported, and the reset spring is compressed, so that the corresponding grid plate 17 moves up to the maximum mileage, and the air inlet on the side wall of the housing 11 is fully opened.

[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 sliding sleeve 43 is respectively plugged and limited with the corresponding connecting ring 47, the rotating shaft 42 drives the gear chain member 45 to move while driving the sliding sleeve 43. Due to the linkage effect of the gear 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 to achieve air cooling of the internal structure of the box body 1. The airflow entering the box body 1 is discharged through the ventilation slot 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 activity, 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 two-way electric push rod 48 to retract a mileage, 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 out of 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 thereon moves in the inclined groove of the corresponding slide plate 161, so that the slide plate 161 moves downward. After the slide plate 161 moves downward, it drives the fixed plate 163 to move downward 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 grid plate 17 to move downward, and the grid plate 17 semi-shields the air inlet, thereby realizing natural air cooling and heat dissipation inside the box body 1.

[0081] If the temperature sensor body 5 in the box body 1 detects that the temperature in the box body 1 is too low, the controller body 6 starts the two-way electric push rod 48 to retract one mile again, so that it retracts to the initial state. The two-way 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 double-axis motor 41 drives the rotating shaft 42 to perform idling activities, and the gear chain member 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 member 49 on the ventilation slot. When the vertical plate 44 retracts again, the adjustment rod 46 thereon moves in the inclined groove of the corresponding slide plate 161, so that the slide plate 161 moves down again. After the slide plate 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 grid plate 17 to move downward again. At this time, except for the topmost air inlet which is in a semi-blocked state, the other air inlets are completely blocked by the grid plate 17, reducing the exchange channel between the internal air of the box 1 and the external air, making full use of the heat generated by the operation of the internal equipment of the box 1, so that the inside of the box 1 reaches a suitable temperature, thereby avoiding 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 the smooth connection between the sliding sleeve 43 and the corresponding connecting ring 47.

[0083] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
