[0058] As Figures 1-11As shown, the drawer-type electric energy meter calibration device of the embodiment comprises a drawer box 10, a drawer unit 20, an auxiliary clamping positioning mechanism and a connection and pushing mechanism 30; wherein the drawer box 10 is internally provided with a plurality of receiving cavities 11 with openings facing the same side, and the receiving cavities 11 extend along a first direction X; the drawer unit 20 comprises a sliding base plate 21 and a front cover plate 22, the sliding base plate 21 is movably arranged in the receiving cavity 11 along the first direction X, the front cover plate 22 is mounted on one side of the sliding base plate 21, and the front cover plate 22 is used to close the opening of the receiving cavity 11 after the sliding base plate 21 is received, the sliding base plate 21 is provided with a placement area for mounting the electric energy meter, and the side of the sliding base plate 21 close to the front cover plate 22 is provided with an electric energy meter calibration wiring device 23 corresponding to the placement area; the auxiliary clamping positioning mechanism is arranged in the placement area and is used to position the installation of the electric energy meter in the first direction X and a second direction Y; the connection and pushing mechanism 30 is arranged on the side of the drawer box 10 away from the front cover plate 22, and the connection and pushing mechanism 30 is used to push the electric energy meter to move along the first direction X and be connected with the electric energy meter calibration wiring device 23 when the sliding base plate 21 is received.

[0059] In this way, the drawer-type design enables the electric energy meter to be horizontally received, greatly saving space compared with the traditional vertical placement, and the drawer-type design enables the electric energy meter to be horizontally placed, which can improve the convenience of operation, facilitate the user to take and place, improve the operation and calibration efficiency, and at the same time, the front cover plate 22 can close the opening of the receiving cavity when the sliding base plate 21 is received, thereby maintaining the cleanliness and safety of the device; the connection and pushing mechanism 30 is used to push the electric energy meter to move along the first direction X and be automatically connected with the electric energy meter calibration wiring device 23 when the sliding base plate 21 is received, thereby reducing manual operation and improving calibration efficiency; in addition, the auxiliary clamping positioning mechanism is arranged in the placement area, which can position the installation of the electric energy meter in the first direction X and the second direction Y, so that the device is suitable for electric energy meters of various models and has strong universality and applicability; and the device can be used in multiple stacks, which does not occupy space and is beneficial to large-scale calibration.

[0060] In the preferred embodiment, the drawer box 10 is internally provided with 5 receiving cavities 11, the drawer unit 20 is 5, and each drawer unit 20 corresponds to one receiving cavity 11, and the sliding base plate 21 can be slidably received or separated from the receiving cavity 11; in other embodiments, since each drawer is independent and similar in structure, the drawer box 10 can also adopt other numbers of receiving cavities 11, which can be selected according to the needs to meet the calibration needs.

[0061] In some embodiments, when the electric energy meter is installed, the electric energy meter to be tested is placed in the placement area of the sliding plate 21, and the auxiliary clamping positioning mechanism is used to accurately position the electric energy meter; then the sliding plate 21 is stored, and the sliding plate 21 is slid along the direction of the storage cavity 11 to be stored in the drawer box 10, and the front cover plate 22 closes the opening of the storage cavity 11; during the storage of the sliding plate 21, the engagement and pushing mechanism 30 pushes the electric energy meter to slide along the placement area until it is automatically connected with the electric energy meter testing wiring device 23; through the connection of the electric energy meter testing wiring device 23 and the position of the terminal post of the electric energy meter, the testing work of the electric energy meter is finally carried out.

[0062] In addition, the drawer type electric energy meter testing device realizes the horizontal storage and automatic connection of the electric energy meter through the storage cavity 11 of the drawer box 10 and the slidable sliding plate 21. Compared with the traditional vertical placement, the horizontal storage greatly saves space; through the pushing action of the engagement and pushing mechanism 30, the electric energy meter can automatically slide to the connection position, which facilitates the testing operation, reduces manual operation, and improves the testing efficiency; and the horizontal placement of the electric energy meter facilitates the user to take and place, and the auxiliary clamping positioning mechanism makes the device applicable to various models of electric energy meters, and has strong universality and applicability.

[0063] It should be noted that the device is suitable for scenarios that require large-scale and efficient electric energy meter testing, such as power companies, testing agencies, etc. The drawer type design can effectively utilize space, improve testing efficiency, and facilitate management and operation.

[0064] In some embodiments, the auxiliary clamping positioning mechanism includes a first clamping positioning assembly 25 and a second clamping positioning assembly 26, the first clamping positioning assembly 25 is used to clamp and position the electric energy meter in the second direction Y; the second clamping positioning assembly 26 is used to clamp and position the electric energy meter in the first direction X, and the first clamping positioning assembly 25 and the second clamping positioning assembly 26 can realize the clamping and positioning of electric energy meters of different models, thereby limiting the position of the electric energy meter during testing, and ensuring the accuracy and efficiency of testing.

[0065] In some embodiments, the sliding plate 21 is provided with an operation channel 211 extending along the second direction Y corresponding to the placement area, both ends of the operation channel 211 are provided with a sliding groove 27, the first clamping positioning assembly 25 includes an operation rotating rod 251, an adjusting screw rod 252 and a placement clamping plate 253, the operation rotating rod 251 is arranged in the operation channel 211 along the second direction Y, the adjusting screw rod 252 is arranged at both ends of the operation rotating rod 251, and the placement clamping plate 253 is movably arranged in the sliding groove 27 along the second direction Y, and the placement clamping plate 253 is threadedly connected with the adjusting screw rod 252, so that the movement of the placement clamping plate 253 in the second direction Y can be realized by rotating the operation rotating rod 251, thereby matching electric energy meters of different models.

[0066] In the above embodiments, the setting direction of the placement clamping plates 253 is the same as the direction of the engagement columns of the electric energy meter calibration wiring device 23, that is, both extend along the first direction X, so that the electric energy meter is docked with the engagement columns of the electric energy meter calibration wiring device 23 after sliding. To realize the movement of the two placement clamping plates 253 towards or away from each other, the screw threads of the adjusting screws 252 at both ends of the operation rotating rod 251 are oppositely arranged, which are used to drive the adjustment of the spacing between the two placement clamping plates 253.

[0067] In some embodiments, when adjusting the positioning and clamping, the operation rotating rod 251 in the channel 211 is operated to synchronously rotate the two adjusting screws 252. Since the screw threads of the two adjusting screws 252 are oppositely arranged, when the operation rotating rod 251 is rotated, the two placement clamping plates 253 move towards or away from each other along the sliding groove 27, thereby adjusting the spacing between the two placement clamping plates 253, realizing accurate positioning, meeting the needs of electric energy meters of various sizes, and avoiding the tilting of the electric energy meter during docking.

[0068] It should be noted that the placement clamping plates 253 only limit the sliding spacing of the electric energy meter in the second direction Y, and do not clamp the electric energy meter. The purpose is to place the electric energy meter between the two placement clamping plates 253 after adjusting the first clamping and positioning assembly 25, slide the sliding base plate 21 in the direction of the storage cavity 11, and make the electric energy meter stored in the drawer box 10. The engagement and pushing mechanism 30 pushes the electric energy meter to slide along the first direction X between the two placement clamping plates 253 of the placement area, and is accurately docked with the engagement columns of the electric energy meter calibration wiring device 23, thereby realizing automatic detection without manual intervention, making the operation more convenient, and ensuring the stability and accuracy of the electric energy meter during the detection process.

[0069] In addition, through the adjustment of the first clamping and positioning assembly 25, the accurate positioning of the electric energy meter during the detection process can be ensured, and the accuracy of the detection is improved. The clamping design of the placement clamping plates 253 can ensure the stability of the electric energy meter during the detection process, and avoid detection errors caused by vibration or displacement. The operation of the two placement clamping plates 253 is controlled by the operation rotating rod 251, which is simple and fast. The device is suitable for electric energy meters of various models and sizes, and has strong universality and applicability.

[0070] In other embodiments, a non-slip sleeve is fixedly arranged on the operation rotating rod 251, which mainly serves to increase the friction between the user's hand and the operation rotating rod 251, and prevent slipping during rotation. The non-slip sleeve is usually made of rubber or other soft materials with good friction coefficient, so as to ensure the stability and safety of the operation.

[0071] In other embodiments, the anti-skid sleeve is not higher than the surface of the sliding seat plate 21 in height when the operation rotating rod 251 is operated, on the one hand, to ensure that the anti-skid sleeve does not interfere with the drawer box 10 or the storage cavity 11 when the sliding seat plate 21 is pushed out or retracted, keeping the operation smooth; on the other hand, to avoid the anti-skid sleeve protruding too high, affecting the appearance and safety of the device.

[0072] It should be noted that when in use, the user only needs to rotate the anti-skid sleeve with the fingers to synchronously rotate the operation rotating rod 251, which can easily rotate the adjusting screw 252, so that the placement clamp plate 253 slides in the second direction Y along the sliding groove 27, changing the position to match different models of electric energy meters.

[0073] In some embodiments, the second clamping and positioning assembly 26 includes four fixed blocks 261 arranged in a rectangular array on the sliding seat plate 21, a guide sliding rod 262 connected between the opposite two fixed blocks 261 along the first direction X, two limiting circular plates 263 sleeved on the guide sliding rod 262, a positioning clamp plate 264 movably sleeved on the guide sliding rod 262 and arranged between the fixed block 261 and the limiting circular plate 263 on the side close to the front cover plate 22, and a pushing plate 266 movably sleeved on the guide sliding rod 262 and arranged between the fixed block 261 and the limiting circular plate 263 on the side away from the front cover plate 22. In a preferred embodiment, the second clamping and positioning assembly 26 further includes a first elastic member 265 and a second elastic member 267 sleeved on the guide sliding rod 262, the first elastic member 265 is arranged between the fixed block 261 and the positioning clamp plate 264 on the side close to the front cover plate 22, and the second elastic member 267 is arranged between the limiting circular plate 263 and the pushing plate 266 on the side away from the front cover plate 22. Through the cooperation of the fixed blocks 261, the guide sliding rod 262, the positioning clamp plate 264, the pushing plate 266, the first elastic member 265 and the second elastic member 267, stable fixing and adjusting functions are provided for the docking process of the electric energy meter and the electric energy meter calibration wiring device 23.

[0074] In the above embodiments, the pushing plate 266 slidably sleeved on the two guide sliding rods 262 is a one-piece plate member, the pushing plate 266 extends along the second direction Y, and the two ends of the pushing plate 266 are slidably connected with the two guide sliding rods 262. In this way, the pushing plate 266 can be arranged corresponding to the position of the abutting bar 34, so that the abutting bar 34 can push the electric energy meter along the first direction X through the pushing plate 266, and the electric energy meter pushes the positioning clamp plate 264 to slide synchronously to complete the docking with the docking column of the electric energy meter calibration wiring device 23.

[0075] In some embodiments, the first elastic member 265 and the second elastic member 267 are preferably springs.

[0076] In the specific embodiment, four fixing blocks 261 are fixedly installed on the sliding plate 21, which are arranged in a rectangular array two by two to provide stable support points for the subsequent guide sliding rods 262. Two guide sliding rods 262 are fixed on two corresponding fixing blocks 261 along the first direction X. The main function of the guide sliding rods 262 is to guide the sliding of the positioning clamping plate 264 and the pushing plate 266, ensuring their stability and accuracy during sliding along the first direction X.

[0077] Exemplarily, two limiting round plates 263 are fixedly sleeved on each guide sliding rod 262, which function to limit the sliding range of the positioning clamping plate 264 and the pushing plate 266, preventing them from sliding out of the guide sliding rod 262. The positioning clamping plate 264 and the pushing plate 266 are slidably sleeved on the guide sliding rod 262, and they are located on the same guide sliding rod 262 on the side away from each other between the two limiting round plates 263. This arrangement provides sufficient sliding space for the positioning clamping plate 264 and the pushing plate 266 on the guide sliding rod 262 to accommodate electric energy meters of different sizes.

[0078] Further, a first elastic member 265 and a second elastic member 267 are also sleeved on each guide sliding rod 262. The arrangement of the elastic members can generate an elastic force when the electric energy meter is placed in the placement area, thereby helping the positioning clamping plate 264 and the pushing plate 266 to better fix the electric energy meter in the first direction X. The first elastic member 265 acts on the pushing plate 266, causing the pushing plate 266 to move and reset away from the electric energy meter verification wiring device 23 when the abutting bar 34 does not abut, and the second elastic member 267 can drive the positioning clamping plate 264 to move and reset away from the electric energy meter verification wiring device 23.

[0079] In some embodiments, the distance between the positioning clamping plate 264 and the pushing plate 266 when stationary is less than that of a typical electric energy meter.

[0080] In some embodiments, in order to maintain the cleanliness and safety inside the device, a locking bolt 28 is threadedly installed on the front cover plate 22, and the side of the drawer box 10 close to the front cover plate 22 is provided with a corresponding screw hole. When the sliding plate 21 is stored in the storage cavity 11, the locking bolt 28 is connected and fixed with the screw hole of the drawer box 10, ensuring the stability of the sliding plate 21 during verification and preventing verification errors caused by accidental sliding or vibration. At the same time, the threaded installation of the locking bolt 28 ensures its firmness and reusable characteristics.

[0081] In other embodiments, the front cover plate 22 is also fixedly installed with a handle 29; the handle 29 fixedly installed on the front cover plate 22 provides a convenient control point for the operator. When it is necessary to take out or move the slide plate 21 and the electric energy meter thereon, the operator can easily pull out or push into the slide plate 21 from the storage cavity 11 by holding the handle 29. This design greatly improves the convenience and efficiency of operation.

[0082] It should be noted that the setting of the locking bolt 28 and the handle 29 further improves the practicability and ease of use of the present embodiment. The locking bolt 28 fixes the slide plate 21 and the drawer box 10 through threaded connection, ensuring the stability during the verification process; and the handle 29 provides a convenient control point for the operator, making it easy to take out and move the slide plate 21.

[0083] In some embodiments, the abutment and pushing mechanism 30 includes a side plate 31 fixedly installed on the side of the drawer box 10 away from the front cover plate 22, the side of the drawer box 10 corresponding to the side plate 31 is provided with a rectangular opening 13, the rectangular opening 13 is staggered with the side plate 31, and a contact bar 34 is slidably installed in the rectangular opening 13, the contact bar 34 extends into the storage cavity 11 and is arranged corresponding to the position of the electric energy meter, the contact bar 34 is staggered with the slide plate 21 and the side plate 31, and the side plate 31 is provided with a motor 37 for driving the contact bar 34 to change position and be positioned, and the motor 37 is used to drive the contact bar 34 to move in the first direction X.

[0084] In some embodiments, when the slide plate 21 is stored into the storage cavity 11, the contact bars 34 located in the rectangular opening 13 will change position in the first direction X under the action of the motor 37. These contact bars 34 extend into the storage cavity 11 and are arranged corresponding to the position of the electric energy meter. Since the contact bars 34 are staggered with the slide plate 21 and the side plate 31, they can directly contact the electric energy meter and push the electric energy meter to slide along the placement area until the abutment column of the electric energy meter verification wiring device 23 is docked.

[0085] In some embodiments, when there are multiple contact bars 34 on the drawer box 10, the motor 37 on the side plate 31 is responsible for controlling the synchronous change of the positions of the multiple contact bars 34 and ensuring that the contact bars 34 can be positioned at appropriate positions when needed. This design enables the abutment and pushing mechanism 30 to be flexibly adjusted according to different sizes and positions of the electric energy meter, ensuring that the electric energy meter can be accurately and stably docked with the verification wiring device.

[0086] In other embodiments, the motor 37 is a servo motor to ensure accurate control of the position of the contact bar 34 in the first direction X.

[0087] In some embodiments, the adapter pushing mechanism 30 realizes automatic pushing and docking of the electric energy meter through the rectangular opening 13 on the side support plate 31 and the slidingly installed abutting strip 34. The introduction of the motor 37 makes this process more flexible and controllable, which can adapt to electric energy meters of different sizes and positions; and the adapter pushing mechanism 30 can automatically push the electric energy meter to dock with the calibration wiring device, reducing the tediousness and errors of manual operation; through the adjustment of the motor 37, the adapter pushing mechanism 30 can adapt to electric energy meters of different sizes and positions, having strong universality and adaptability; the stable pushing of the abutting strip 34 ensures the stability of the electric energy meter during docking, avoiding calibration errors caused by vibration or displacement; the operator only needs to control the motor 37 to realize the automatic docking of the electric energy meter, which is simple and fast to operate.

[0088] In some embodiments, the rectangular guide opening 36 is formed on the abutting strip 34, and the rectangular guide block 14 fixedly connected with the inner wall of the rectangular opening 13 is slidably arranged in the rectangular guide opening 36; by forming the rectangular guide opening 36 on the abutting strip 34 and arranging the rectangular guide block 14 fixedly connected with the inner wall of the rectangular opening 13 in the rectangular guide opening 36, higher stability and precision are provided for the adapter pushing mechanism 30. When the motor 37 starts to work, it will push the abutting strip 34 to slide in the rectangular opening 13. Since the rectangular guide block 14 is fixedly connected with the inner wall of the rectangular opening 13 and is slidably arranged in the rectangular guide opening 36 of the abutting strip 34, the sliding of the abutting strip 34 will be along the rectangular guide block 14, ensuring the stability and linearity of the sliding. This design enables the abutting strip 34 to more accurately push the electric energy meter to dock with the calibration wiring device.

[0089] It should be noted that the cooperation of the rectangular guide block 14 and the rectangular guide opening 36 actually forms a sliding guide mechanism. This guide mechanism restricts the freedom of the abutting strip 34 during sliding, so that it can only move linearly along the first direction X.

[0090] In some embodiments, the adapter pushing mechanism 30 further comprises a plurality of rotating shafts 32 rotatably installed on the side support plate 31 and a tensioning wheel 310, the plurality of rotating shafts 32 are respectively arranged in the first direction X and staggered with the plurality of abutting strips 34, the abutting strips 34 located on one side of the rotating shafts 32 are each formed with a gear set 35, the rotating shafts 32 are each fixedly sleeved with an adjusting gear 33 and a synchronous wheel 39, the adjusting gear 33 is engaged with the gear set 35, the tensioning wheel 310 and the synchronous wheel 39 are located on the same side of the side support plate 31, the synchronous wheel 39 and the tensioning wheel 310 are sleeved with a synchronous belt 38, the side support plate 31 is fixedly installed with the motor 37, and the output shaft of the motor 37 is in transmission connection with the synchronous belt 38.

[0091] In some embodiments, the motor 37 is started when it is necessary to adjust the position of the abutting bars 34 to push the electric energy meter to be in contact with the testing wiring device. The output shaft of the motor 37 drives all the synchronous wheels 39 to rotate through the synchronous belt 38, thereby driving the adjusting gears 33 through the rotating shaft 32. Since the adjusting gears 33 are engaged with the toothed groups 35, the rotation of the adjusting gears 33 can be converted into the linear motion of the abutting bars 34, i.e. driving the abutting bars 34 to slide in the rectangular opening 13, thereby achieving the automatic pushing and contacting of the electric energy meter in the first direction X.

[0092] It should be noted that the abutting pushing mechanism 30 adopts a combination of gear and rack transmission and synchronous belt transmission. The motor 37 is used as a power source to transmit power to other rotating shafts 32 through the synchronous belt 38, thereby achieving the synchronous rotation of the rotating shafts 32. The adjusting gears 33 on each rotating shaft 32 are engaged with the toothed groups 35 on the abutting bars 34, thereby converting the rotary motion of the rotating shafts into the linear motion of the abutting bars 34, i.e. achieving the synchronous linear motion of the abutting bars 34 in the first direction X, thereby achieving the automatic pushing and contacting of the electric energy meter. Through the motor driving and synchronous belt transmission, the synchronous motion of the abutting bars is achieved, the automatic pushing and contacting of the electric energy meter is achieved, and the tediousness and errors of manual operation are reduced. Since the gear and rack transmission is adopted, the linear motion of the abutting bars has high accuracy, thereby ensuring the accurate contacting of the electric energy meter and the testing wiring device. Through the synchronous belt transmission, the synchronous rotation of the rotating shafts is achieved, thereby improving the efficiency of the entire motor 37, and thereby improving the efficiency of the electric energy meter testing. The entire motor 37 has simple and compact structure, is easy to maintain, and reduces the use cost.

[0093] In other embodiments, the abutting bars 34 are arranged in an "L" shape to avoid slipping with the adjusting gears 33. Specifically, the abutting bars 34 are an "L" shaped structure formed by connecting a longer straight segment and a shorter segment perpendicular thereto. The longer straight segment not only has the toothed groups 35, but also is used to contact and push the electric energy meter, while the shorter perpendicular segment is used for limiting. When the motor 37 is started and drives the rotating shaft 32 to rotate, the adjusting gears 33 will also rotate. Since the abutting bars 34 are arranged in an "L" shape, the shorter perpendicular segment can limit the adjusting gears 33 in the first direction X, thereby ensuring that there is no slippage or misplacement during the driving process. At the same time, the longer straight segment can smoothly push the electric energy meter into or out of the receiving cavity 11.

[0094] In some embodiments, a guide groove 12 is formed on each of the two side inner walls of the receiving cavity 11, and a guide block 210 is slidably installed in each of the guide grooves 12 and fixedly connected with the slide plate 21. By forming the guide grooves 12 on the two side inner walls of the receiving cavity 11 and slidably installing the guide blocks 210 in the guide grooves 12 and fixedly connecting the guide blocks 210 with the slide plate 21, the stability and smoothness of the slide plate 21 sliding in the receiving cavity 11 are further enhanced. When it is necessary to move the slide plate 21, an operator can push the slide plate 21 through the handle 29 or other operating devices. Since the two sides of the slide plate 21 are fixed with the guide blocks 210, the guide blocks 210 slide in the guide grooves 12 of the two side inner walls of the receiving cavity 11, thereby ensuring the stable sliding of the slide plate 21 in the receiving cavity 11.

[0095] In addition, the guide grooves 12 and the guide blocks 210 form a sliding guide system. This system limits the movement trajectory of the slide plate 21 in the receiving cavity 11, so that the slide plate 21 can only slide in the first direction X. The cooperation of the guide grooves 12 and the guide blocks 210 ensures the stable sliding of the slide plate 21 in the receiving cavity 11, avoiding the inconvenience or safety accidents caused by the shaking or deviation of the slide plate 21. Since the sliding of the slide plate 21 is more stable and smooth, the operator can more quickly and accurately complete the calibration, replacement or maintenance of the electric energy meter, thereby improving the work efficiency.

[0096] In some embodiments, the length of the receiving cavity 11 in the first direction X is equal to the length of the slide plate 21 in the first direction X, so that the slide plate 21 can be completely slid into the receiving cavity 11 and will not be exposed outside the drawer box 10, thereby ensuring the neatness and beauty of the device. Since the length of the slide plate 21 is completely matched with the length of the receiving cavity 11, the sliding of the slide plate 21 in the receiving cavity 11 is more stable, and the possibility of shaking and deviation is reduced.

[0097] In some embodiments, the height of the front cover plate 22 in the third direction Z is equal to the height of the drawer box 10 in the third direction Z, and the height of the front cover plate 22 in the third direction Z is greater than the opening height of the receiving cavity 11. The height design of the front cover plate 22 makes it not only able to completely cover the opening part of the drawer box 10, but also able to embed and block part of the opening of the receiving cavity 11, and also facilitates the fixation of the locking bolt 28 with the drawer box 10. This design not only enhances the beauty of the device, but also can prevent dust or other sundries from entering the inside of the receiving cavity 11 to some extent, thereby maintaining the cleanliness and safety of the electric energy meter.

[0098] In another embodiment, in order to further improve the use effect of the drawer type electric energy meter calibration device, the drawer type electric energy meter calibration device further comprises a heat dissipation opening 24 arranged on the sliding seat plate 21, the heat dissipation opening 24 corresponds to the connection position of the electric energy meter and the electric energy meter calibration wiring device 23, and the bottom inner wall of each of the plurality of receiving cavities 11 is fixedly provided with a connecting channel 15, the connecting channel 15 is open on one side of the sliding seat plate 21, the top of the connecting channel 15 is located on the same plane as the bottom of the sliding seat plate 21, and after the sliding seat plate 21 is completely received in the receiving cavity 11, the connecting channel 15 is in sealed butt joint with the heat dissipation opening 24. The outer wall of the drawer box 10 is fixedly provided with a flow guide cylinder 40, the plurality of connecting channels 15 and the flow guide cylinder 40 are connected through a through pipe 16, and any opening of the flow guide cylinder 40 is provided with a fan 41, and the fan 41 discharges air outside the flow guide cylinder 40.

[0099] In some embodiments, the plurality of sliding seat plates 21 are each provided with a heat dissipation opening 24, and the positions of the heat dissipation openings 24 correspond to the connection positions of the electric energy meter and the electric energy meter calibration wiring device. Such a design is to ensure that the heat generated during the operation of the electric energy meter and the wiring device can be effectively dissipated, so as to avoid overheating affecting the normal operation of the equipment.

[0100] In some embodiments, in order to achieve the heat dissipation effect, the bottom inner wall of the receiving cavity 11 is provided with a connecting channel 15. The connecting channel 15 is open on one side of the sliding seat plate 21, and the top of the connecting channel 15 is located on the same plane as the bottom of the sliding seat plate 21. When the sliding seat plate 21 is completely received in the receiving cavity 11, the connecting channel 15 is in sealed butt joint with the heat dissipation opening 24. Such a design ensures that when the sliding seat plate 21 is received, the heat dissipation opening 24 thereon can be tightly connected with the connecting channel 15 to form a closed heat dissipation channel. The plurality of connecting channels 15 and the flow guide cylinder 40 are connected through the through pipe 16 to form a continuous heat dissipation path. Any opening of the flow guide cylinder 40 is provided with a fan 41, and the fan 41 discharges air outside the flow guide cylinder 40. In use, when the electric energy meter and the wiring device on the sliding seat plate 21 work, the heat generated will enter the connecting channel 15 through the heat dissipation opening 24 and flow to the flow guide cylinder 40 through the through pipe 16. At this time, the fan 41 starts to work to discharge the heat from the flow guide cylinder 40, thereby achieving effective heat dissipation effect. In order to ensure air circulation, a ventilation opening (not shown) can be arranged on any one of the drawer box 10 or the front sealing plate 22, or a rectangular opening 13 can be used to introduce air to ensure the need for air circulation, so that air can enter the receiving cavity 11.

[0101] It should be noted that by setting the heat dissipation port 24, the connection channel 15, the guide pipe 16 and the guide air cylinder 40, not only can the electric energy meter and the wiring device be effectively cooled to prevent overheating, but also the opening and closing of the cooling channel can be realized by the storage of the sliding seat plate 21 and the connection of the connection channel 15, so that the cooling process is more flexible and controllable. At the same time, the addition of the fan 41 further enhances the cooling effect and improves the stability and reliability of the equipment.

[0102] In some embodiments, the height of the guide air cylinder 40 is equal to the height of the drawer box 10, and the guide air cylinder 40 is provided with a connecting lug 42 at the upper and lower portions. The drawer box 10 can be used alone or stacked together, and only the connection of the multiple drawer boxes 10 and the connection of the multiple guide air cylinders 40 by the connecting lug 42 and the bolt connection can make the air duct uniform, as shown in Figure 11 .

[0103] The working process of the present application is as follows: Figures 1-11 As shown in the figure, in the use process, the distance between the two placing clamps 253 is adjusted according to the size of the electric energy meter, when the electric energy meter is placed on the placing clamp 253, the bottom of the electric energy meter will contact the positioning clamp 264, and the top will contact the push plate 266. Since the distance between the positioning clamp 264 and the push plate 266 is smaller than the usual electric energy meter when it is static, the positioning clamp 264 slides downward to compress the corresponding first elastic member 265, so as to ensure that the electric energy meter can be clamped and fixed between the positioning clamp 264 and the push plate 266. When the sliding seat plate 21 is slid into the storage cavity 11 to complete the fixation, the abutting strip 34 will push the push plate 266 to slide on the guide sliding rod 262, and then push the electric energy meter to move in the direction of the electric energy meter calibration wiring device 23. In this process, the positioning clamp 264 will also slide synchronously and tightly fit with the bottom corner of the electric energy meter, so as to realize the stable fixation of the electric energy meter. At the same time, due to the existence of the first elastic member 265 and the second elastic member 267, the whole fixation and calibration process is more stable, and the shaking or deviation of the electric energy meter in the connection process is avoided. When unlocked, each part is reset under the rebound of the elastic member.
