[0047] See also Figure 1 and Figure 2 , a protective device provided in an embodiment of the present application includes a dustproof mechanism 100 and a driving mechanism, wherein the dustproof mechanism 100 is used to control the metering device B ( Figure 7 ) on the interface mechanism 500 ( Figure 7 ) for protection, it can be driven away from the interface mechanism 500 by the driving mechanism to make the interface mechanism 500 open, so that the operator can connect the wire to the interface mechanism 500 to achieve the measurement of electricity, and it can also be driven by the driving mechanism to cover the interface mechanism 500 to make the interface mechanism 500 closed, thereby achieving dust prevention and protection for the interface mechanism 500. Wherein:

[0048] The dustproof mechanism 100 includes a dustproof plate 110, a linkage assembly 120 and a trigger assembly 130. The dustproof plate 110 is movably covered on the interface mechanism 500, and the linkage assembly 120 is fixedly connected to the dustproof plate 110 and the linkage assembly 120 is movably abutted against the trigger assembly 130. When the trigger assembly 130 releases the linkage assembly 120, the linkage assembly 120 can drive the dustproof plate 110 away from the interface mechanism 500 to open the interface mechanism 500, which is convenient for operators to connect or remove wires. Conversely, when the trigger assembly 130 abuts and pushes the linkage assembly 120, the linkage assembly 120 can drive the dustproof plate 110 close to the interface mechanism 500 to cover the interface mechanism 500, thereby protecting the interface and preventing dust and water vapor from entering the interface mechanism 500.

[0049] The driving mechanism includes a connecting assembly 210 and a holding assembly 220. The connecting assembly 210 is fixedly connected to the trigger assembly 130, and the holding assembly 220 is fixedly connected to the connecting assembly 210; when the holding assembly 220 moves, the movement can be transmitted to the trigger assembly 130 through the connecting assembly 210, that is, the holding assembly 220 drives the connecting assembly 210 to drive the trigger assembly 130 to resist or release the linkage assembly 120.

[0050] When in use, the operator holds the entire metering mechanism through the force application point provided by the holding component 220, and drives the connection component 210 by operating the holding component 220 to drive the trigger component 130 to release the linkage component 120, so that the linkage component 120 synchronously drives the dustproof plate 110 away from the interface mechanism 500 to open the interface mechanism 500 for wiring or disconnecting; when not in use, the operator operates again, holds the holding component 220 tightly to fully open the dustproof plate 110, removes the wires connected to the interface mechanism 500, and then releases the holding component 220 to reset the holding component 220, and during the resetting process drives the connection component 210 to drive the trigger component 130 to resist or push the linkage component 120, so that the linkage component 120 synchronously drives the dustproof plate 110 close to the interface mechanism 500 to cover the interface mechanism 500 and achieve protection of the interface.

[0051] In this embodiment, by setting a dustproof mechanism 100 and a driving mechanism, the dustproof mechanism 100 includes a dustproof plate 110 movably covered on the interface mechanism 500 of the metering device B, a linkage component 120 fixedly connected to the dustproof plate 110 and driving the dustproof plate 110 to open and block the interface mechanism 500, and a trigger component 130 movably abutting against the linkage component 120; the driving mechanism includes a connecting component 210 fixedly connected to the trigger component 130, a holding component 220 fixedly connected to the connecting component 210 and driving the connecting component 210 to drive the trigger component 130 to abut or release the linkage component 120, the dustproof plate 110 covers the interface mechanism 500, and the dustproof plate 110 is fixedly connected to the trigger component 130. Through the cooperation between the linkage component 120 and the trigger component 130, the interface mechanism 500 can be opened or blocked according to the wiring needs to achieve dust prevention and protection of the interface mechanism 500, and the trigger component 130 is triggered by the connection component 210 and the holding component 220, and the holding component 220 can provide enough force application space so that the connection component 210 drives the trigger component 130 to move synchronously, and then the dustproof plate 110 is synchronously driven to move through the movable contact between the trigger component 130 and the linkage component 120, so that the dustproof plate 110 can quickly and efficiently open and block the interface mechanism 500, so as to improve the metering efficiency of the electricity.

[0052] In one embodiment, the linkage assembly 120 at least includes a linkage structure (not shown in the figure) arranged at the first end of the dustproof plate 110, and correspondingly, the trigger assembly 130 includes a trigger plate 131 that is movably abutted against the linkage structure. In specific implementation, linkage structures are usually arranged at both ends of the dustproof plate 110, and each linkage structure is correspondingly provided with a trigger plate 131 that is movably abutted therewith. In this way, force can be applied to both ends of the dustproof plate 110 at the same time to ensure the stable movement of the dustproof plate 110, and it can support the setting of a relatively long dustproof plate 110. When the dustproof plate 110 is long, some guide structures or pulley structures can be arranged in the middle of the dustproof plate 110 to maintain the stable movement of the dustproof plate 110; it is understandable that in some other embodiments, the trigger plate 131 of the linkage structure can also be arranged only at one end of the dustproof plate 110. In this case, if it is necessary to improve the stability of the movement of the dustproof plate 110, a slide groove, pulley or guide structure can be arranged between the other end of the dustproof plate 110 and the metering device B to assist the movement of the dustproof plate 110.

[0053] When a linkage structure and a trigger plate 131 are provided at both ends of the dustproof plate 110, since the linkage structure and the trigger plate 131 at both ends have the same structure, the present embodiment is described below taking the linkage structure and the trigger plate 131 provided at the first end of the dustproof plate 110 as an example.

[0054] The linkage structure includes a connecting plate 121, a fixing plate 122 and a linkage member 123. The connecting plate 121 is fixedly connected to the first end of the dustproof plate 110, the fixing plate 122 is arranged on the metering device B, the linkage member 123 is arranged between the connecting plate 121 and the fixing plate 122, one end of the linkage member 123 is fixedly connected to the connecting plate 121, the other end of the linkage member 123 is movably penetrated on the fixing plate 122 and the passing end of the linkage member 123 is movably abutted against the trigger plate 131, and through the action of the linkage member 123, the connecting plate 121 can be driven to approach or move away from the fixing plate 122, and then the dustproof plate 110 is driven to move on the interface mechanism 500 through the connecting plate 121.

[0055] In an optional embodiment, the connecting plate 121 is L-shaped, including a horizontal plate 121a and a vertical plate 121b. The horizontal plate 121a is fixedly connected to the vertical plate 121b. The horizontal plate 121a is connected to the linkage member 123, and the vertical plate 121b is connected to the dustproof plate 110 to optimize the spatial layout of the entire linkage structure and realize the miniaturization and compactness of the structure of the entire dustproof device.

[0056] In one embodiment, see Figure 3 and Figure 4The linkage member 123 includes a guide rod 123a, a first spring 123b and a force plate 123c. The guide rod 123a is fixed on the connecting plate 121, the first spring 123b is sleeved on the guide rod 123a, and the force plate 123c is fixed on the guide rod 123a and corresponds to the end away from the connecting plate 121; the end of the guide rod 123a away from the connecting plate 121 is penetrated on the fixing plate 122, the force plate 123c is fixed on the passing end of the guide rod 123a, and the force plate 123c is movably abutted against the trigger plate 131, one end of the first spring 123b is fixed to the connecting plate 121, and the other end of the first spring 123b is fixed to the fixing plate 122. The trigger plate 131 includes a horizontal plate 131b and a vertical plate 131c vertically arranged on the horizontal plate 131b, the vertical plate 131c is arranged at an angle to the moving direction of the guide rod 123a, and an open groove 131a is formed between the horizontal plate 131b and the vertical plate 131c, the open groove 131a is arranged toward the force-bearing plate 123c, and the cross-sectional area of ​​the open groove 131a along the vertical plane gradually decreases from the outside to the inside, wherein the vertical plane is a plane perpendicular to the horizontal plate 131b and parallel to the moving direction of the guide rod 123a. Such arrangement enables the trigger plate 131 to release the force-bearing plate 123c when it moves inward, thereby causing the force-bearing plate 123c and the guide rod 123a to move toward the trigger plate 131, at which time the force-bearing plate 123c is away from the fixed plate 122, and enables the trigger plate 131 to push the force-bearing plate 123c when it moves outward, thereby causing the force-bearing plate 123c and the guide rod 123a to move toward the direction away from the trigger plate 131, at which time the force-bearing plate 123c is close to the fixed plate 122.

[0057] When the interface mechanism 500 is opened, the trigger plate 131 moves inward under the drive of the driving mechanism to release the force plate 123c, so that the force of the trigger plate 131 on the force plate 123c is reduced and is less than the reset force of the first spring 123b. Since the action stroke of the trigger plate 131 is limited, the force plate 123c will not completely separate from the trigger plate 131, that is, the force of the trigger plate 131 on the force plate 123c will not disappear, so that the connection plate is driven by the reset action of the first spring 123b. 121 as a whole moves toward the direction approaching the fixed plate 122 so that the dustproof plate 110 opens the interface mechanism 500; conversely, when closing the interface mechanism 500, the trigger plate 131 is reset and moves outward under the reset action of the driving mechanism to push the force-bearing plate 123c, so that the force on the force-bearing plate 123c is greater than the compression force of the first spring 123b and compresses the first spring 123b, thereby pushing the connecting plate 121 as a whole to move away from the fixed plate 122, so that the dustproof plate 110 resets and closes the interface mechanism 500.

[0058] In an optional embodiment, the linkage assembly 120 includes a first linkage structure and a second linkage structure respectively arranged at both ends of the dustproof plate 110, and the trigger assembly 130 includes a first trigger plate movably abutting against the first linkage structure and a second trigger plate movably abutting against the second linkage structure, so as to increase the stability of the movement of the dustproof plate. In specific implementation, the first linkage structure and the second linkage structure have the same structure and are symmetrically arranged, and the structure of the linkage structure recorded in the above embodiment can be referred to. The structure of the first trigger plate and the second trigger plate have the same structure and are symmetrically arranged, and the structure of the trigger plate recorded in the above embodiment can be referred to, and no further description is given here.

[0059] In one embodiment, see Figure 1 , Figure 4 and Figure 5 The connecting assembly 210 includes a first connecting rod 211 and a second connecting rod 212, wherein the first connecting rod 211 is connected to the first trigger plate, and the second connecting rod 212 is connected to the second trigger plate. The holding assembly 220 includes a first holding member 221, a second holding member 222, and a second spring 223, wherein the first holding member 221 is connected to the first connecting rod 211, and the second holding member 222 is connected to the second connecting rod 212, and the second spring 223 is disposed between the first holding member 221 and the second holding member 222. In an optional embodiment, corresponding to the number of the trigger plates 131, the first connecting rod 211 and the second connecting rod 212 are respectively fixedly connected to the trigger plates 131 at one end, so as to transmit the force exerted by the operator on the first holding member 221 and the second holding member 222 to the corresponding trigger plates 131.

[0060] When in use, the first gripping member 221 and the second gripping member 222 provide a force application space for the operator to hold the entire device. By applying force on the first gripping member 221 and the second gripping member 222, the first gripping member 221 and the second gripping member 222 are brought close to each other and the second spring 223 is compressed. In the process of the first gripping member 221 and the second gripping member 222 approaching each other, the first gripping member 221 and the second gripping member 222 respectively drive the connected first connecting rod 211 and the second connecting rod 212 to move inward synchronously, and the trigger assembly 130 is driven to act through the first connecting rod 211 and the second connecting rod 212, so as to realize the linkage of the linkage assembly 120 and open the interface machine. Structure 500; when not in use, the operator releases the first gripping member 221 and the second gripping member 222, so that the external force on the first gripping member 221 and the second gripping member 222 is smaller than the restoring force of the second spring 223, and they move away from each other under the restoring action of the second spring 223. In the process of the first gripping member 221 and the second gripping member 222 moving away from each other, the first gripping member 221 and the second gripping member 222 respectively drive the connected first connecting rod 211 and the second connecting rod 212 to move outward synchronously, and the trigger assembly 130 is driven to operate through the first connecting rod 211 and the second connecting rod 212, thereby realizing the linkage of the linkage assembly 120 and closing the interface mechanism 500.

[0061] In an optional embodiment, the connecting assembly 210 further includes a first limiting column 213 and a second limiting column 214 disposed inside the metering device B, and the first limiting column 213 and the second limiting column 214 are fixed inside the metering device. A third limiting groove (not shown) is disposed inside the first limiting column 213, and the first connecting rod 211 is movably disposed in the third limiting groove so that the third limiting groove limits the movement of the first connecting rod 211. When the first connecting rod 211 moves, the third limiting groove can limit the first connecting rod 211 in the third limiting groove, ensuring the stable movement of the first connecting rod 211; a fourth limiting groove (not shown) is disposed inside the second limiting column 214, and the second connecting rod 212 is movably disposed in the fourth limiting groove so that the fourth limiting groove limits the movement of the second connecting rod 212. When the second connecting rod 212 moves, the fourth limiting groove can limit the second connecting rod 212 in the fourth limiting groove, ensuring the stable movement of the second connecting rod 212. In specific implementation, the number of the first limit column 213 and the second limit column 214 can be set to multiple to improve the stability of the corresponding connecting rod movement. The specific number can be set based on comprehensive considerations such as the size of the connecting rod and the stability requirements, and this embodiment does not make specific restrictions.

[0062] The first gripping member 221 includes a first connecting portion 221a and a first handle 221b. The first connecting portion 221a is fixedly connected to the first connecting rod 211, and the first connecting portion 221a is slidably arranged in the metering device B. The first handle 221b is used to provide a force application space for the operator to hold. The first connecting portion 221a can be slidably connected to the corresponding position in the metering device B through a slide groove. When a force is applied to the first handle 221b, the first connecting portion 221a slides in the metering device B to drive the first connecting rod 211 to move inward or outward. The first handle 221b is connected to the first connecting portion 221a and can rotate around the first connecting portion 221a. Correspondingly, a first storage area (not shown) can be set at a corresponding position on the metering device B. When not in use, the first handle 221b can be rotated and flipped into the first storage area, so as to avoid the first handle 221b extending out of the metering device B when stored and affecting the storage stability. Optionally, the first storage area may be a first storage groove capable of accommodating the first handle 221b, so that it can be stored in the first storage groove after the first handle 221b is flipped over. In some other embodiments, the first storage area may also be a planar area, and a first magnetic block is arranged on the first storage area, and a first magnetic block is also arranged at a corresponding position on the first handle 221b. After the first handle 221b is flipped over to the first storage area, the first handle 221b can be fixed to the first storage area by the adsorption force of the two first magnetic blocks to further improve the stability of the first storage area; of course, when setting the first storage groove, a corresponding first magnetic block may also be arranged to improve the storage stability.

[0063] Similar to the structure of the first gripping member 221, the second gripping member 222 includes a second connecting portion 222a and a second handle 222b, and a second spring 223 is fixed between the first connecting portion 221a and the second connecting portion 222a. The second connecting portion 222a is fixedly connected to the second connecting rod 212, and the second connecting portion 222a is slidably arranged in the metering device B. The second handle 222b is used to provide a force application space for the operator to hold. The second connecting portion 222a can be slidably connected to the corresponding position in the metering device B through a slide groove. When a force is applied to the second handle 222b, the second connecting portion 222a slides in the metering device B to drive the second connecting rod 212 to move inward or outward. The second handle 222b is connected to the second connection part 222a and can rotate around the second connection part 222a. Correspondingly, a second storage area (not shown) can be set in the corresponding position on the metering device B. When not in use, the second handle 222b can be rotated and flipped into the second storage area, so as to prevent the second handle 222b from extending out of the metering device B when stored and affecting the storage stability. Optionally, the second storage area can be a second storage groove that can accommodate the second handle 222b, so that the second handle 222b can be stored in the second storage groove after flipping. In some other embodiments, the second storage area can also be a plane area, and a second magnetic block is set on the second storage area, and a second magnetic block is also set at a corresponding position on the second handle 222b. After the second handle 222b is flipped to the second storage area, the second handle 222b can be fixed in the second storage area by the adsorption force of the two second magnetic blocks to further improve the storage stability; of course, when the second storage groove is set, a second magnetic block can also be set accordingly to improve the storage stability.

[0064] In an optional embodiment, the driving mechanism further includes a limiter 230 disposed inside the metering device B, and the limiter 230 is located between the first gripping member 221 and the second gripping member 222 to limit the first gripping member 221 and the second gripping member 222. The limiter 230 includes a middle partition 231, a first limiter pin 232, and a second limiter pin 233; the middle partition 231 is fixed inside the metering device B, the first limiter pin 232 is disposed on the middle partition 231 and on a side opposite to the first gripping member 221, and the second limiter pin 233 is disposed on the middle partition 231 and on a side opposite to the second gripping member 222 to cooperate with the first gripping member 221 and the second gripping member 222 to limit the position.

[0065] Correspondingly, a first limiting groove (not shown) is provided on the side of the first handle 221b facing the second handle 222b, and the first limiting groove is provided corresponding to the first limiting pin 232, and can limit the first limiting pin 232 when the first handle 221b approaches inward; a second limiting groove 222c is provided on the side of the second handle 222b facing the first handle 221b, and the second limiting groove 222c is provided corresponding to the second limiting pin 233, and can limit the second limiting pin 233 when the second handle 222b approaches inward. Through the cooperation and limitation of the first limiting groove and the first limiting pin 232 and the cooperation and limitation of the second limiting groove 222c and the second limiting groove 222c, the first handle 221b and the second handle 222b can be prevented from rotating relative to their respective corresponding connecting parts after they approach each other, thereby increasing the stability of the first handle 221b and the second handle 222b during use.

[0066] In an alternative embodiment, see Figure 1 and Figure 6 The protective device also includes an anti-collision mechanism 300 to prevent the metering device B from being damaged by collision or falling during use, so as to further improve the protective effect.

[0067] The anti-collision mechanism 300 includes at least one anti-collision component arranged on the periphery of the metering device B. Taking four anti-collision components as an example, the four anti-collision components are respectively arranged on the four corners of the metering device B to protect the metering device B. Of course, in some other embodiments, the number of anti-collision components can be determined according to actual protection requirements, that is, more or fewer anti-collision components are arranged on the periphery of the metering device B.

[0068] Each anti-collision component includes a cushioning airbag 310 and an inflation and deflation structure 320. The cushioning airbag 310 is correspondingly arranged on the periphery of the metering device B. The inflation and deflation structure 320 is connected to the cushioning airbag 310 so as to inflate the cushioning airbag 310 during use, thereby protecting the metering device B, and to deflate the cushioning airbag 310 when not in use, which can facilitate storage and prevent the cushioning airbag 310 from being in an inflated state for a long time and causing fatigue failure.

[0069] In an exemplary embodiment, the inflation and deflation structure 320 includes a piston cylinder 321, a piston rod 322 and a connecting air pipe 323. The piston cylinder 321 is fixed inside the metering device B by means of a structure such as a buckle or a bolt, and the connecting air pipe 323 connects the piston cylinder 321 and the buffer airbag 310; the interior of the piston cylinder 321 is hollow, and the piston rod 322 is movably arranged in the piston cylinder 321, and the first end of the piston rod 322 is sealedly connected to the inner wall of the piston cylinder 321, and the first end of the piston rod 322 is slidably connected to the inner wall of the piston cylinder 321 to form a variable space 321a in the piston cylinder 321, one end of the connecting air pipe 323 is connected to the variable space 321a, and the other end is connected to the buffer airbag 310, and the piston cylinder 321 is connected to the buffer airbag 310 through the piston rod 322. The sliding movement inside 321 can change the volume of the variable space 321a. When the piston rod 322 compresses the variable space 321a forward (i.e. inward), the air in the variable space 321a is passed into the cushioning airbag 310 through the connecting air pipe 323, so that the cushioning airbag 310 is inflated to play a protective role. When the piston rod 322 releases the variable space 321a backward (i.e. outward), a relative negative pressure is formed in the variable space 321a, and the air in the cushioning airbag 310 is sucked into the variable space 321a through the connecting air pipe 323, so that the cushioning airbag 310 is deflated and contracted for easy storage. The second end of the piston rod 322 is fixedly connected to the connecting component 210. With such an arrangement, the connecting component 210 can synchronously drive the piston rod 322 to move when driving the trigger plate 131 to move, so as to drive the trigger plate 131 and the piston rod 322 at the same time, so that when in use, only one operation is needed to simultaneously realize the opening of the dustproof plate 110 and the inflation of the buffer airbag 310, as well as the closing of the dustproof plate 110 and the deflation of the buffer airbag 310, so as to improve the convenience of use. Moreover, the two are driven by a unified driving mechanism, which is conducive to further optimizing the spatial layout of the entire linkage structure and further realizing the miniaturization and compactness of the structure of the entire dustproof device. At the same time, after the dustproof plate 110 is opened, the operator connects the wire to the wiring mechanism. Since the moving direction of the dustproof plate 110 is perpendicular to the plug-in direction of the wire, the wire or the plug on the wire can be against the edge of the dustproof plate 110 to prevent the dustproof plate 110 from resetting. In addition, since the dustproof plate 110 is fixed to the linkage assembly 120, it can continuously abut against the trigger assembly 130 through the linkage assembly 120, so that the trigger assembly 130 will not be reset, and then the connecting assembly 210 will also not be reset, and the drive 322 can be maintained in the state of the compressed variable space 321a, and the buffer airbag 310 continues to inflate to achieve buffering and collision prevention of the metering device B.

One end of the linkage assembly 120 passes through the outside of the metering body 400 and is fixed to the dustproof plate 110. The connecting assembly 210 and the gripping assembly 220 are arranged inside the metering body 400. One end of the gripping assembly 220 away from the connecting assembly 210 extends to the outside of the metering body 400 to form a gripping portion 224. The gripping portion 224 is used to provide a gripping space for the operator to hold the entire device.

[0074] In an exemplary embodiment, the data acquisition module 610 can be implemented by a sensor chip of the ACS758 series to collect data such as voltage, current, and power of the electric energy meter through the wires connected to the interface mechanism 500. The data processing module 620 can be implemented by a filter chip of the SCT2650STER model to filter and correct data such as voltage, current, and power to improve the accuracy of electricity metering. The calculation module 630 can be implemented by an i.MX RT series cross-border processor to perform calculations on the electricity metering data processed by the data processing module 620, and determine whether there is incorrect wiring or abnormal conditions according to preset rules.

[0075] In an optional embodiment, the processing mechanism 600 further includes a communication module 640, which is in communication connection with the data acquisition module 610, the data processing module 620 and the calculation module 630, and can transmit the electricity metering data and the electricity data to the cloud, so as to realize data exchange between the processing mechanism 600 and the cloud.
