The voltage-detecting power pressure plate includes a pressure plate body 100, a voltage-detecting activation / deactivation device 200, and a control module.

[0046] The pressure plate body 100 includes a first electrode 110, a second electrode 120, and a connecting piece. Figure 1 In the middle, the connecting piece is covered and blocked by other structures. The connecting piece rotates with the second electrode 120 to electrically connect or disconnect the second electrode 120 from the first electrode 110, so that the voltage test plate can be switched between the closed state and the fully open state.

The voltage detection device 200 includes a housing 210 and a drive assembly DM, a first voltage detection wheel 230, a first voltage detection element 250, a second voltage detection wheel 240, and a second voltage detection element 260 mounted on the housing 210. In some embodiments, the housing 210 includes a first housing portion 211 and a second housing portion 212 detachably connected to each other. The drive assembly DM is throttle-connected to the first voltage detection wheel 230 and the second voltage detection wheel 240. The second voltage detection wheel 240 is throttle-connected to the second electrode 120 to drive the second electrode 120 to rotate. The first voltage detection wheel 250 can drive the first voltage detection element 250 to contact or separate from the first electrode 110, and the second voltage detection wheel 240 can drive the second voltage detection element 260 to contact or separate from the second electrode 120, and drive the second electrode 120 to rotate.

[0048] The control module is electrically connected to the drive component DM. The control module is configured to, before controlling the drive component DM to drive the second electrode 120 to rotate via the second voltage-detecting wheel 240 to switch to the closed state or the fully open state, control the drive component DM to drive the first voltage-detecting element 250 to contact the first electrode 110 to detect voltage on the first electrode 110, and control the drive component DM to drive the second voltage-detecting element 260 to contact the second electrode 120 to detect voltage on the second electrode 120 via the second voltage-detecting wheel 240.

[0049] According to an embodiment of the present invention, a voltage-detecting pressure plate includes a voltage-detecting activation / deactivation device 200. The device 200 includes a drive assembly DM, a first voltage-detecting wheel 230, a first voltage-detecting element 250, a second voltage-detecting wheel 240, and a second voltage-detecting element 260. The second voltage-detecting wheel 240 is tractively connected to a second electrode 120 to drive the second electrode 120 to rotate, thereby enabling remote control of the pressure plate body 100's state switching. The first voltage-detecting wheel 250 can drive the first voltage-detecting element 250 to contact or separate from the first electrode 110, enabling voltage detection of the first electrode 110 when the first voltage-detecting element 250 is in contact with the first electrode 110. The second voltage-detecting wheel 240 can drive the second voltage-detecting element 260 to contact or separate from the second electrode 120, enabling voltage detection of the second electrode 120 when the second voltage-detecting element 260 is in contact with the second electrode 120. The control module is configured to, before the control drive assembly DM drives the second electrode 120 to rotate via the second voltage-detecting wheel 240 to switch to the closed state or the fully open state, drive the first voltage-detecting element 250 to contact the first electrode 110 to detect voltage in the first electrode 110, and drive the second voltage-detecting element 260 to contact the second electrode 120 to detect voltage in the second electrode 120, via the second voltage-detecting wheel 240. By setting the first voltage-detecting wheel 230, the first voltage-detecting element 250, the second voltage-detecting wheel 240, and the second voltage-detecting element 260, and by controlling the drive assembly DM via the control module, control of the above components can be achieved. This enables automated or remote voltage detection of whether the first electrode 110 and the second electrode 120 are energized, ensuring the safety of the pressure plate body 100 during engagement and disengagement operations.

[0050] In some embodiments, rotation of the second electrode 120 causes the pressure plate body 100 to have a fully separated state, an electric detection state, and a closed state. In the fully separated state and the electric detection state, the second electrode 120 is disconnected from the first electrode 110. In the closed state, the second electrode 120 is electrically connected to the first electrode 110.

[0051] In the fully open and closed states, the first voltage detector 250 is disconnected from the first electrode 110, and the second voltage detector 260 is disconnected from the second electrode 120.

[0052] In the voltage detection state, the first voltage detector 250 is in contact with the first electrode 110 or the second voltage detector 260 is in contact with the second electrode 120.

[0053] In the above embodiments, in the fully open and closed states, the first voltage detector 250 is disconnected from the first electrode 110, and the second voltage detector 260 is disconnected from the second electrode 120, to prevent the secondary circuit from short-circuiting due to equipment failure of the switching device and to ensure the power supply safety of the substation.

[0054] In this embodiment, the first voltage detector 250 is an elastic element, and the first voltage detector wheel 250 deforms when it rotates. The first voltage detector 250 is connected to the first voltage detector wheel 230 and deforms when the first voltage detector wheel 230 rotates, so that the first voltage detector 250 can switch between contacting or separating from the first electrode 110.

[0055] In this embodiment, the second voltage detector 260 is an elastic element, which is driven to deform when the second voltage detector wheel 240 rotates. The second voltage detector 260 is connected to the second voltage detector wheel 240 and deforms when the second voltage detector wheel 240 rotates, so that the second voltage detector 260 can switch between contacting or separating from the second electrode 120.

[0056] In some embodiments, the first voltage detector 250 and the second voltage detector 260 are spring structures. The first voltage detector 250 and the second voltage detector 260 each include a fixing portion for fixed connection with the housing 210 and a deformable portion capable of elastic deformation relative to the fixing portion. In some embodiments, the deformable portion includes a straight-line extension structure. The deformable portion of the first voltage detector 250 can contact or disconnect from the first electrode 110, and the deformable portion of the second voltage detector 260 can contact or disconnect from the second electrode 120.

[0057] Figure 3 This is a perspective view of the first voltage testing wheel 230 in one embodiment of the voltage testing plate of the present invention. In some embodiments, the first voltage testing wheel 230 has a first push shoulder 231, which abuts against the first voltage testing element 250 and pushes the first voltage testing element 250 to deform when the first voltage testing wheel 230 rotates.

[0058] Figure 4 , Figure 5 This is a perspective view and a cross-sectional view of the second voltage testing wheel 240 in one embodiment of the voltage testing plate of the present invention. In some embodiments, the second voltage testing wheel 240 has a second push shoulder 241, which abuts against the second voltage testing element 260 and pushes the second voltage testing element 260 to deform when the second voltage testing wheel 240 rotates.

[0059] In some embodiments, after the first voltage detector 250 is installed in the housing 210, it disconnects from the first electrode 110 without external force. When the first voltage detector wheel 230 rotates, the first push shoulder 231 pushes the first voltage detector 250 to deform, causing the first voltage detector 250 to switch between contacting or disconnecting from the first electrode 110.

[0060] In some embodiments, after the second voltage detector 260 is installed in the housing 210, it contacts the second electrode 120 without external force. When the second voltage detector wheel 240 rotates, the second push shoulder 241 pushes the second voltage detector 260 to deform, causing the second voltage detector 260 to switch between contacting and disconnecting from the second electrode 120.

[0061] like Figure 3 In some embodiments, the first push shoulder 231 is provided to protrude relative to the outer peripheral surface of the first electrodetector wheel 230.

[0062] like Figure 4 , Figure 5 In some embodiments, the cross-sectional shape of the second push shoulder 241 is U-shaped and arranged around the second electrode 120.

[0063] In some embodiments, at least a portion of the outer peripheral surface of the first electrodetector wheel 230 is provided with a first transmission tooth 232 for transmission connection.

[0064] In some embodiments, at least a portion of the outer peripheral surface of the second electrodetector wheel 240 is provided with a second transmission tooth 242 for transmission connection.

[0065] Figure 6 This is a perspective view of the first electrode 110 and the second electrode 120 in one embodiment of the voltage-detecting plate of the present invention. In some embodiments, one end of the second voltage-detecting wheel 240 is provided with a transmission hole 243. The second electrode 120 has a transmission block 121, the shape of which matches the shape of the transmission hole 243. The transmission block 121 is inserted into the transmission hole 243, so that the second voltage-detecting wheel 240 can drive the second electrode 120 to rotate.

[0066] In some embodiments, the transmission hole 243 and the transmission block 121 are polygons, such as quadrilaterals.

[0067] In some embodiments, the drive assembly DM includes a drive element 220 and a drive wheel 270 connected to a shaft 221 of the drive element 220. The drive element 220 is, for example, a motor.

[0068] In the above embodiment, a single driving component 220 is used as the power source. The drive component 220 is decelerated through the transmission structure such as the transmission wheel 270 and the second voltage detection wheel 240, thereby amplifying the torque of the driving component 220 and outputting it to the second electrode 120 of the pressure plate body 100, so that it rotates and reciprocates. Compared with a dual driving component power source, the power of the driving component 220 can be reduced in the same volume, making the control simpler and more efficient.

[0069] In some embodiments, the drive assembly DM further includes a transmission cam 280. Figure 7This is a perspective view of the transmission wheel 270 and transmission cam 280 in one embodiment of the voltage testing plate of the present invention. In this embodiment, the transmission wheel 270 has a hollow structure, and a first abutment protrusion 271 is provided on the inner circumferential surface of the transmission wheel 270. The drive assembly DM also includes a transmission cam 280. The transmission cam 280 is coaxially connected to the rotating shaft 221 and passes through the transmission wheel 270. A second abutment protrusion 281 is provided on the outer circumferential surface of the transmission cam 280. The transmission cam 280 rotates to cause the second abutment protrusion 281 to abut or separate from the first abutment protrusion 271, and drives the transmission wheel 270 to rotate when the second abutment protrusion 281 abuts against the first abutment protrusion 271.

[0070] In the above embodiment, the transmission cam 280 rotates to cause the second abutting protrusion 281 to abut or separate from the first abutting protrusion 271. The transmission structure between the transmission cam 280 and the transmission wheel 270 can have a large free stroke. Therefore, when the pressure plate body 100 is manually operated, the pressure plate body 100 will not drive the drive component DM to rotate, thus improving the user experience.

[0071] like Figure 1 In some embodiments, the voltage-testing pressure plate further includes a circuit board 300 and a housing 400. The circuit board 300 is electrically connected to the drive assembly DM, and a control module is disposed on the circuit board 300. The circuit board 300 is electrically connected to the first voltage-testing element 250 and the second voltage-testing element 260. The circuit board 300 and the voltage-testing deployment / retraction device 200 are installed inside the housing 400, and a portion of the pressure plate body 100 is located outside the housing 400, with the first electrode 110 and the second electrode 120 extending into the housing 400. In some embodiments, the housing 400 includes a base 410 and a cover 420 that are detachably connected to each other.

[0072] like Figure 2 In some embodiments, the drive assembly DM further includes an idler wheel GT, the first electrodetector wheel 230 is connected to the drive wheel 270 via the idler wheel GT, and the second electrodetector wheel 240 is connected to the drive wheel 270 via the idler wheel GT.

The outer circumferential surface of the idler wheel GT is provided with multiple fourth transmission teeth G1. A third transmission tooth 272 meshes with a first transmission tooth 232, and the third transmission tooth 272 also meshes with the fourth transmission tooth G1, while the fourth transmission tooth G1 meshes with a second transmission tooth 242.

[0075] Figure 8 In some embodiments, the outer peripheral surface of the idler wheel GT is also provided with symmetrical limiting protrusions G2, which cooperate with the limiting ribs on the housing 210 to ensure that the rotation angle of the idler wheel GT does not exceed 90 degrees.

[0076] In some embodiments, the control module includes a photoelectric sensor 310. In some embodiments, the photoelectric sensor 310 is disposed on a circuit board 300. Figure 2 In some embodiments, the drive assembly DM further includes a rotation control wheel 290. The rotation control wheel 290 is coaxially connected to the idler wheel GT. The rotation control wheel 290 is located outside the housing 210. The rotation control wheel 290 can trigger the photoelectric sensor 310 when it rotates to a plurality of preset positions. The pressure plate body 100 also has a first voltage detection state for detecting voltage on the first electrode 110 and a second voltage detection state for detecting voltage on the second electrode 120. Based on the feedback signals generated by the photoelectric sensor 310 triggered by the rotation control wheel 290 rotating to different preset positions, the control module controls the drive assembly DM to switch the pressure plate body 100 to a fully separated state, a first voltage detection state, a second voltage detection state, or a closed state.

[0077] In some embodiments, the photoelectric sensor 310 is a U-shaped photoelectric sensor 310.

[0078] Figure 9 This is a perspective view of the rotating control wheel 290 in one embodiment of the voltage-detecting pressure plate of the present invention. In some embodiments, the outer periphery of the rotating control wheel 290 is provided with a plurality of detection protrusions 291 arranged at intervals along the circumference, and a detection groove 292 is provided between adjacent detection protrusions 291. When the rotating control wheel 290 rotates, the detection protrusions 291 and the detection grooves 292 pass through the photoelectric sensor 310 alternately in sequence. In this embodiment, the outer periphery of the rotating control wheel 290 is provided with four detection grooves 292 arranged at intervals along the circumference. Each detection groove 292 can trigger the photoelectric sensor 310. When the four detection grooves 292 are respectively aligned with the photoelectric sensor 310, the pressure plate body 100 is in a fully separated state, a first voltage-detecting state, a second voltage-detecting state, and a closed state in sequence.

[0079] In some embodiments, adjacent detection slots 292 are spaced apart by an angle of 30° along the rotation direction of the rotation control wheel 290.

[0080] In this embodiment, the rotation of the second electrode 120 causes the pressure plate body 100 to have a fully separated state, an electrical detection state, and an engaged state. The electrical detection state includes a first electrical detection state and a second electrical detection state. In the fully separated state and the electrical detection state, the second electrode 120 is disconnected from the first electrode 110. In the engaged state, the second electrode 120 is electrically connected to the first electrode 110.

[0081] When the four detection slots 292 are aligned with the photoelectric sensor 310, they correspond to the fully separated state, the first voltage detection state, the second voltage detection state, and the closed state in sequence.

[0082] Figure 10 This is a cross-sectional schematic diagram of the voltage detection device in a fully separated state according to an embodiment of the voltage detection power plate of the present invention. In the fully separated state, the second electrode 120 is disconnected from the first electrode 110, the first voltage detection element 250 is disconnected from the first electrode 110, and the second voltage detection element 260 is disconnected from the second electrode 120.

[0083] Figure 11 This is a cross-sectional schematic diagram of a voltage-detecting power plate according to an embodiment of the present invention, showing a voltage-detecting activation / deactivation device in the first voltage-detecting state. In the first voltage-detecting state, the second electrode 120 and the connecting piece rotate 30° relative to the fully separated state, and the rotation control wheel 290 rotates 30° relative to the fully separated state. At this time, the second electrode 120 is disconnected from the first electrode 110, the first voltage-detecting element 250 is in contact with the first electrode 110, and the second voltage-detecting element 260 is disconnected from the second electrode 120.

[0084] Figure 12 This is a cross-sectional schematic diagram of the voltage testing device in the second voltage testing state, according to an embodiment of the voltage testing power plate of the present invention. In the second voltage testing state, the second electrode 120 and the connecting piece continue to rotate 30° in the first voltage testing state, and the rotation control wheel 290 continues to rotate 30° relative to the first voltage testing state. At this time, the second electrode 120 is disconnected from the first electrode 110, the second voltage testing element 260 is in contact with the second electrode 120, and the first voltage testing element 250 is disconnected from the first electrode 110.

[0085] Figure 13 This is a cross-sectional schematic diagram of the voltage testing device in the closed position according to an embodiment of the voltage testing power plate of the present invention. In the closed position, the second electrode 120 and the connecting piece continue to rotate 30° in the second voltage testing state, and the rotation control wheel 290 continues to rotate 30° relative to the second voltage testing state. At this time, the second electrode 120 is electrically connected to the first electrode 110, the first voltage testing element 250 is disconnected from the first electrode 110, and the second voltage testing element 260 is disconnected from the second electrode 120.

[0086] In the above embodiments, in the fully open and closed states, the first voltage detector 250 is disconnected from the first electrode 110, and the second voltage detector 260 is disconnected from the second electrode 120, to prevent the secondary circuit from short-circuiting due to equipment failure of the switching device and to ensure the power supply safety of the substation.

[0087] This invention also provides a control method for a voltage-detecting power plate, which is used for a voltage-detecting power plate in any of the foregoing embodiments. The control method includes steps S110 to S140.

[0088] In step S110, the power test plate is in the first state. In response to the received switching command, it controls the drive component DM to start rotating. The first state is either the closed state or the fully open state.

[0089] In step S120, the control drive component DM drives the first voltage detector 250 to contact the first electrode 110 through the first voltage detector wheel 250 to detect voltage on the first electrode 110.

[0090] In step S130, the control drive component DM drives the second voltage detector 260 to contact the second electrode 120 via the second voltage detector wheel 240 to detect voltage on the second electrode 120.

[0091] The order of steps S120 and S130 is not limited. In some embodiments, step S120 is performed first and then step S130 is performed. In other embodiments, step S130 is performed first and then step S120 is performed.

[0092] In step S140, after the first electrode 110 and the second electrode 120 are tested for voltage respectively, the control drive component DM drives the second electrode 120 to rotate through the second voltage testing wheel 240, so that the voltage testing power plate switches to the second state, which is the other of the fully separated state and the closed state.

[0093] The following example, using the preparation of a power tester plate to switch from a fully open state to a closed state, will further illustrate the above control method.

[0094] In this example, in step S110, the power test plate is in a fully open state and responds to the received on / off switching command to control the drive component DM to start rotating.

[0095] In this example, in step S120, the control drive component DM drives the second electrode 120 to rotate via the second voltage detection wheel 240, causing the voltage detection plate to leave the fully separated state, and the control drive component DM drives the first voltage detection element 250 to contact the first electrode 110 via the first voltage detection wheel 250 to detect voltage on the first electrode 110.

[0096] In this example, in step S130, the control drive component DM drives the first voltage detector 250 to separate from the first electrode 110 via the first voltage detector wheel 250, and controls the drive component DM to drive the second voltage detector 260 to contact the second electrode 120 via the second voltage detector wheel 240 to detect voltage on the second electrode 120.

[0097] In this example, in step S140, after the first electrode 110 and the second electrode 120 are tested for voltage respectively, the control drive component DM drives the second voltage testing element 260 to separate from the second electrode 120 through the second voltage testing wheel 240, and controls the drive component DM to drive the second electrode 120 to rotate through the second voltage testing wheel 240 so that the voltage testing power plate switches to the closed state.

[0098] In the above example, the process of switching the voltage tester plate from the fully open state to the closed state is used as an example. The process of switching the voltage tester plate from the closed state to the fully open state is equivalent to the reverse process of the above example process, and will not be described in detail.

[0099] According to the control method of the power plate capable of voltage detection according to the embodiment of the present invention, upon receiving the switching command, the first electrode 110 and the second electrode 120 are voltage-tested sequentially. After the voltage testing of the first electrode 110 and the second electrode 120 is completed respectively, the control drive component DM drives the second electrode 120 to rotate through the second voltage testing wheel 240, thereby switching the power plate capable of voltage detection to a fully open or closed state. This realizes automated or remote voltage testing of whether the first electrode 110 and the second electrode 120 are energized, ensuring the safety of the power plate body 100 during the switching operation.

[0100] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made under the concept of the present invention using the description and drawings of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
