Description

Technical Field

[0001] The present application relates to the technical field of power supply metering equipment, and in particular to an intelligent electric energy metering box. Background Art

[0002] An energy meter box is a device used to measure electrical energy. It includes an energy meter, voltage and current transformers and their secondary circuits, as well as auxiliary equipment such as energy meter panels, cabinets, and boxes. Energy meter boxes are typically used in low-voltage power distribution systems. They operate by assembling switchgear, measuring instruments, protective devices, and auxiliary equipment within a closed or semi-enclosed metal cabinet or panel.

[0003] At present, during the use of outdoor electricity meter boxes, the electricity meter boxes may malfunction and need to be repaired by operators. The operators need to disconnect the power supply first, and then open the box door for maintenance. After the maintenance is completed, the operator turns the box door handle and uses the card block to lock the box door.

[0004] Regarding the above-mentioned related technologies, the inventor believes that there are no good monitoring measures for outdoor electricity meter boxes. After daily maintenance and fault disconnection and reconnection operations, it is easy for the box door to be not closed or not closed tightly, which may easily cause electric shock and poor safety. Summary of the Invention

[0005] In order to improve the safety of an electric energy meter box, the present application provides an intelligent electric energy meter box.

[0006] The present application provides an intelligent electric energy meter box that adopts the following technical solutions:

[0008] By adopting the above technical solution, the operator connects the power line on the electric energy meter box to the first metal block and the second metal block respectively. When the electric energy meter box needs to be inspected, the operator turns the handle of the box door. The rotation of the handle drives the insulating rope to move, and the movement of the insulating rope drives the moving block to move. The movement of the moving block drives the connecting block to move. The movement of the connecting block compresses the driving spring, and the connecting block is separated from the first metal block and the third metal block, thereby disconnecting the power supply in the electric energy meter box; when the operator closes the box door and turns the handle to lock the box door, the moving block drives the connecting block to move under the action of the driving spring, and the connecting block moves between the first metal block and the third metal block, thereby energizing the electric energy meter box; when the operator closes the box door but does not lock it, the connecting block is always separated from the first metal block and the third metal block, so that the system prompts the operator in the terminal background that the electric energy meter box cannot be powered on, thereby playing a monitoring role for the outdoor electric energy meter box, thereby preventing electric shock and improving the safety of the electric energy meter box.

[0009] Preferably, a rotating plate is fixedly connected to the box door, a rotating rod is fixedly connected to the rotating plate, rotating blocks are provided at both ends of the rotating rod, the rotating rod is rotatably connected to the rotating block, a roller is installed on the end of the rotating rod that penetrates into the rotating block, and the end of the insulating rope away from the transmission roller passes around the roller and is fixedly connected to the moving block.

[0010] By adopting the above technical solution, the insulating rope passes through the box door and enters the box body through the roller on the rotating rod and is fixedly connected to the moving block, thereby reducing the friction between the insulating rope and the box body and improving the flexibility of the insulating rope.

[0011] Preferably, a connecting groove for plugging with the connecting block is provided on the end of the first metal block close to the connecting block, and the connecting block can abut against the inner wall of the connecting groove, and a slope is provided on the end of the third metal block close to the connecting block, and a slope is provided on the end of the connecting block close to the third metal block, and the slope on the third metal block matches the slope on the connecting block.

[0012] By adopting the above technical solution, when the operator closes the box door and turns the handle to lock the box door, the moving block drives the connecting block to move under the action of the driving spring, and the inclined surface of the connecting block slides on the inclined surface of the third metal block. The moving block continues to move so that the connecting block is inserted into the connecting groove under the action of the inclined surface. The connecting block is pressed against the inclined surface of the third metal block under the action of the driving spring, and the bottom end of the connecting block is pressed against the inner wall of the connecting groove under the action of the inclined surface, thereby improving the conductive stability of the connecting block and preventing the power line from being broken.

[0014] By adopting the above technical solution, the curved surface of the first wave plate makes the end of the first wave plate press tightly against the gate plate, thereby improving the conductivity of the gate plate and the second metal block. The operator uses the limiting assembly to drive the gate plate to move, and the end of the gate plate slides on the curved surface of the second wave plate, reducing the resistance of the gate plate to insert into the second wave plate and the insulating plate, making it convenient for the operator to connect the second metal block and the third metal block. When the operator opens the box door, the operator uses the limiting assembly to drive the gate plate away from the second wave plate, thereby disconnecting the second metal block and the third metal block, preventing the operator from accidentally touching the handle, causing the third metal block and the second metal block to be energized and causing electric shock to people, thereby improving the safety of the equipment.

The operator uses the fixing component to release the fixed state of the limit column, and the limit column moves under the action of the limit spring. The movement of the limit column drives the gate plate to move, and the movement of the gate plate disconnects the second metal block from the third metal block, thereby cutting off the power supply; when the operator completes the maintenance, the operator moves the limit rubber plate, and the movement of the limit rubber plate drives the gate plate to move, and the gate plate drives the limit column to move. The movement of the limit column causes the limit spring to be in a compressed state, and then the operator uses the fixing component to fix the limit column, thereby facilitating the operator's recycling.

[0018] By adopting the above technical solution, the operator uses the control component to drive the fixed block to move, the movement of the fixed block causes the fixed gear to rotate, the rotation of the fixed gear drives the fixed rack to move, the movement of the fixed rack causes the fixed rack to move away from the fixed slide, thereby releasing the fixed state of the gate; the operator uses the control component to drive the fixed block to move, the fixed block drives the fixed rack to move through the fixed gear, and the fixed rack is inserted into the fixed slide, thereby fixing the gate.

[0019] Preferably, the control component includes a first airbag fixedly connected to the fixed block and a second airbag penetrating the side wall of the box body. The insulating plate is provided with a control slide groove for slidingly cooperating with the fixed block. The end of the first airbag away from the fixed block is fixedly connected to the inner end face of the control slide groove. The first airbag is communicated with the second airbag. A compression component for compressing and deforming the second airbag is provided on the box body.

[0020] By adopting the above technical solution, the operator uses the compression assembly to compress the second airbag, and the compression deformation of the second airbag causes the first airbag to expand and deform, and the expansion deformation of the first airbag drives the fixed block to move, thereby facilitating the use of the operator.

[0021] Preferably, the compression assembly includes a compression rack passed through the box body and a compression gear fixedly mounted on the rotating rod, the compression rack is engaged with the compression gear, the compression rack is fixedly connected to the second airbag, and a compression groove for slidingly cooperating with the compression rack is provided on the box body, and the end of the second airbag away from the compression rack is fixedly connected to the inner end face of the compression groove.

[0022] By adopting the above technical solution, the operator opens the box door to rotate the rotating rod, the rotation of the rotating rod causes the compression gear to rotate, the rotation of the compression gear causes the compression rack to move, the movement of the compression rack drives the second airbag to compress, the compression of the second airbag drives the first airbag to expand and deform, the expansion and deformation of the first airbag causes the fixed block to move, the fixed block drives the fixed rack to move through the fixed gear, thereby causing the gate to move, thereby disconnecting the power supply and improving the safety of the box.

[0024] By adopting the above technical solution, when the operator completes the maintenance, the operator drives the gate plate through the limiting rubber plate, and the movement of the gate plate drives the limiting column to move. The movement of the limiting column causes the positioning rod to enter the positioning slide groove under the action of the inclined surface. At this time, the positioning spring is in a compressed state. When the positioning rod moves to the position of the fixed slide groove, the positioning rod enters the fixed slide groove under the action of the positioning spring, and then the operator closes the box door. The box door causes the second airbag to expand and deform through the rotating rod. The expansion and deformation of the second airbag causes the first airbag to shrink. The contraction of the first airbag drives the fixed block to move. The fixed block moves to cause the positioning rod to move away from the fixed slide groove. The fixed block drives the fixed gear through the fixed gear to be inserted into the fixed slide groove, so that the gate plate is always connected to the third metal block, which is convenient for the operator to use.

Then the operator opens the door, and the door drives the fixed block to move through the rotating rod. The movement of the fixed block causes the locking rod to slide in the locking slot. Under the action of the inclined surface, the locking rod drives the locking rod to insert into the locking slot, thereby locking the movable block. The locking rod compresses the locking spring through the locking disc, thereby preventing the movable block from resetting; the operator closes the door to move the fixed block, and the movement of the fixed block causes the locking rod to enter the locking slot, thereby releasing the fixation of the movable block, which is convenient for the operator to recycle.

The connecting block is pressed against the inclined surface of the third metal block under the action of the driving spring. The bottom end of the connecting block is pressed against the inner wall of the connecting groove under the action of the inclined surface, thereby improving the conductive stability of the connecting block and preventing the power line from being broken.

[0030] 3. The operator turns the door handle to move the moving block. The movement of the moving block separates the connecting block from the first metal block and the second metal block.

[0061] Referring to the figure, the insulating plate 12 is provided with a fixing assembly 3 for fixing the limiting column 22. The fixing assembly 3 includes a fixing rack 31, a fixing gear 32, and a fixing block 33. The fixing rack 31 is inserted through the insulating plate 12. The end of the fixing rack 31 that extends beyond the inner wall of the limiting groove 25 enters the limiting column 22. The limiting column 22 is provided with a fixing slot 34. The sidewalls of the fixing rack 31 slideably engage the inner wall of the fixing slot 34. The end of the fixing rack 31 that extends into the fixing slot 34 is provided with an inclined surface.

[0062] Reference Figure 7 The fixed gear 32 is vertically arranged and rotatably mounted on the insulating plate 12. The fixed gear 32 meshes with the fixed rack 31.

The insulating plate 12 is provided with a control slot 43. The outer wall of the fixed block 33 slides with the inner wall of the control slot 43. The fixed block 33 is provided with a positioning rod 35.

[0063] Reference Figure 7 The positioning rod 35 is horizontally disposed and extends through the fixed block 33. The fixed block 33 is provided with a positioning slot 36. The outer wall of the positioning rod 35 slides in engagement with the inner wall of the positioning slot 36. The end of the positioning rod 35 extending beyond the fixed block 33 can be inserted into the limiting column 22. The side wall of the end of the positioning rod 35 extending beyond the fixed block 33 slides in engagement with the inner wall of the fixed slot 34. The end of the positioning rod 35 extending into the fixed slot 34 is provided with an inclined surface. A positioning spring 37 is provided on the positioning rod 35. The positioning spring 37 is horizontally disposed and fixedly connected to the positioning rod 35. The end of the positioning spring 37 away from the positioning rod 35 is fixedly connected to the inner end surface of the positioning slot 36.

[0064] When the operator has completed the inspection, the operator drives the gate plate 17 to move through the limiting rubber plate 21. The movement of the gate plate 17 drives the limiting column 22 to move, so that the positioning rod 35 enters the positioning slot 36 under the action of the inclined surface. At this time, the positioning spring 37 is in a compressed state. The operator continues to move the gate plate 17. When the positioning rod 35 moves to the position of the fixed slot 34, the positioning rod 35 enters the fixed slot 34 under the action of the positioning spring 37, thereby fixing the position of the gate plate 17.

[0065] Reference Figure 3 、 Figure 7 The housing 1 is provided with a control assembly 4 for driving the fixed block 33 to move. The control assembly 4 includes a first airbag 41 and a second airbag 42. The first airbag 41 is arranged horizontally and disposed within a control chute 43. One end of the first airbag 41 is fixedly connected to the fixed block 33, and the end of the first airbag 41 away from the fixed block 33 is fixedly connected to the inner end surface of the control chute 43. The second airbag 42 is arranged horizontally and communicates with the first airbag 41. A compression chute 53 is defined on the insulating plate 12. The second airbag 42 is disposed within the compression chute 53 and fixedly connected to the inner end surface of the compression chute 53.

[0066] Reference Figure 3 The housing 1 is provided with a compression assembly 5 for compressing and deforming the second airbag 42. The compression assembly 5 includes a compression rack 51 and a compression gear 52. The compression rack 51 is horizontally disposed and extends through the housing 1. The outer wall of the compression rack 51 slides with the inner wall of a compression chute 53. The end of the compression rack 51 extending into the compression chute 53 is fixedly connected to the second airbag 42. The compression gear 52 is horizontally disposed and disposed within the rotating block 115. The compression gear 52 is fixedly mounted on the end of the rotating rod 114 located within the rotating block 115 and meshes with the compression rack 51.

[0067] The operator opens the box door 11, and the box door 11 drives the rotating rod 114 to rotate through the rotating plate 113, and the rotating rod 114 drives the compression rack 51 to move through the compression gear 52, and the compression rack 51 drives the first air bag 41 to expand and deform through the second air bag 42, and the expansion and deformation of the first air bag 41 drives the fixed block 33 to move, and the fixed block 33 drives the fixed rack 31 away from the fixed slide groove 34 through the fixed gear 32, so that the gate plate 17 is separated from the second wave plate 151 under the action of the limit spring 23, thereby disconnecting the current between the second metal block 14 and the third metal block 15, preventing the operator from accidentally touching the handle, causing the third metal block 15 and the second metal block 14 to be energized and causing electric shock to people, thereby improving the safety of equipment maintenance.

[0068] The operator moves the limiting rubber plate 21 so that the gate 17 is fixed by the positioning rod 35. Then the operator closes the box door 11. The rotation of the box door 11 drives the compression rack 51 to move. The compression rack 51 drives the second air bag 42 to shrink through the first air bag 41. The contraction of the second air bag 42 causes the positioning rod 35 to move away from the fixed slide groove 34, and the fixed rack 31 enters the fixed slide groove 34. At this time, the limiting column 22, under the action of the limiting spring 23, makes the inner wall of the fixed slide groove 34 abut against the side wall of the fixed rack 31, thereby fixing the position of the gate 17, maintaining the current of the second metal block 14 and the third metal block 15, and preventing power circuit breaker.

[0069] Reference Figure 5 、 Figure 7 The locking rod 121 is vertically arranged and slides through the housing 1. A locking slot 126 is formed on the bottom surface of the fixing block 33. The inner sidewall of the locking slot 126 slides with the sidewall of the locking rod 121. The end of the locking rod 121 that extends into the inner end of the locking slot 126 is provided with an inclined surface. The end of the locking rod 121 away from the fixing block 33 can extend into the locking groove 125, and the sidewall of the locking rod 121 can abut against the inner sidewall of the locking groove 125.

[0070] Reference Figure 5 、 Figure 7 The locking rod 121 is provided with a horizontally disposed locking disc 122, which is sleeved onto the locking rod 121 and fixedly connected to the locking rod 121. A vertically disposed sliding groove 124 is defined on the insulating plate 12, with the inner sidewall of the sliding groove 124 slidingly engaging with the outer sidewall of the locking disc 122. A vertically disposed locking spring 123 is sleeved on the locking rod 121, with one end fixedly connected to the locking disc 122 and the other end fixedly connected to the inner end surface of the sliding groove 124.

[0071] The operator turns the handle to move the movable block 16, which drives the connecting block 161 away from the first metal block 13 and the third metal block 15. The operator then opens the door 11, causing the fixed block 33 to move. The movement of the fixed block 33 causes the locking rod 121 to slide within the locking slot 126. The locking rod 121 moves under the action of the inclined surface, causing the bottom of the locking rod 121 to insert into the locking slot 125 of the movable block 16, thereby fixing the position of the movable block 16. The operator closes the door 11, causing the fixed block 33 to move. The movement of the fixed block 33 causes the top of the locking rod 121 to insert into the locking slot 126, thereby moving the bottom of the locking rod 121 away from the locking slot 125, releasing the fixed state of the movable block 16 and facilitating the operator to close the switch and turn on the power.

[0072] The implementation principle of an intelligent electricity meter box in an embodiment of the present application is as follows: when the outdoor electricity meter box is being repaired, the operator turns the handle so that the connecting block 161 is away from the first metal block 13 and the third metal block 15, so that the electricity meter box is powered off. Then the operator opens the box door 11 so that the gate 17 is away from the second wave plate 151. At this time, the locking rod 121 fixes the position of the movable block 16 to prevent the operator from accidentally touching the handle, so that the third metal block 15 and the second metal block 14 are energized and cause electric shock to people, thereby improving the safety of the equipment.

[0073] When the operator completes the inspection, the operator pulls the limiting rubber plate 21, so that the second metal block 14 and the third metal block 15 are energized. Then the operator closes the box door 11 so that the gate plate 17 is fixed by the fixed rack 31, which is convenient for the operator to recycle. At this time, the locking rod 121 is away from the moving block 16, and the moving block 16 is released from the fixed state. Then the operator turns the handle and locks the box door 11 again. At this time, the moving block 16 drives the connecting block 161 under the action of the handle to energize the first metal block 13 and the third metal block 15, which is convenient for the normal use of the electricity meter box.

[0074] When the operator closes the box door 11 but does not lock it, the connecting block 161 is always separated from the first metal block 13 and the third metal block 15, and the electricity meter box cannot be powered on, thereby reminding the maintenance personnel to lock the box door 11. The system prompts the monitoring personnel in the terminal background that the electricity meter box cannot be powered on, thereby playing a monitoring role on the outdoor electricity meter box, thereby preventing the electricity meter box from being accidentally opened and causing electric shock, and improving the safety of the electricity meter box.

[0075] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
