[0037] like Figures 1 to 10 As shown, a high-safety power grid switch device of this embodiment includes a base 100, a first drive assembly 400 and a second drive assembly. A mounting plate 110 is provided on the base 100, and a mounting hole 111 is provided on the mounting plate 110. In actual operation, the base 100 can be installed on an external transformer device or other equipment by using fasteners such as bolts to pass through the mounting hole 111, and the installation is simple and convenient. Two groups of knife gate assemblies 200 are movably provided on the base 100. The knife gate assemblies 200 include a connecting member 210 and a rotating member 220. The connecting member 210 is connected to the wire 300, and the rotating member 220 is rotatably provided on the base 100.

[0038] In the embodiment, the two groups of blade assemblies 200 are movably arranged on the base 100, and the connection members 210 of the two groups of blade assemblies 200 are abutted or separated from each other by the movement of the two groups of blade assemblies 200 to realize the operation of power-on or power-off. Specifically, when the power-on operation is performed, the two groups of rotating members 220 are driven to rotate by the first driving assembly 400, so that the two groups of blade assemblies 200 are rotated to the first position, at which the connection members 210 of the two groups of blade assemblies 200 are abutted and connected with the wires 300 connected with the two groups of connection members 210, and the power-on operation is completed. When the power-off operation is performed, the two groups of rotating members 220 are driven to rotate by the first driving assembly 400, so that the two groups of blade assemblies 200 are rotated away from the first position, at which the connection members 210 of the two groups of blade assemblies 200 are separated from each other and the wires 300 connected with the two groups of connection members 210 cannot be connected, and the power-off operation is completed.

[0039] Further, the second driving assembly is arranged to drive the two groups of blade assemblies 200 to relatively approach or move away from each other. In the power-on operation, the second driving assembly drives the two groups of blade assemblies 200 to relatively approach each other, so that the rotating tracks of the two groups of connection members 210 intersect, and the two groups of connection members can abut each other during the rotation of the rotating members 220. In the power-off operation, the second driving assembly drives the two groups of blade assemblies 200 to relatively move away from each other, so that the rotating tracks of the two groups of connection members 210 do not intersect, and even if the first driving assembly 400 is mistakenly turned on to drive the two groups of blade assemblies 200 to rotate, the two groups of connection members 210 cannot abut each other, thereby effectively avoiding the situation that the blade device is powered on due to the mistaken touch of the switch, and the safety of the operator during the circuit maintenance process is ensured.

[0040] In one of the embodiments, the first driving assembly 400 includes a driving motor 410, a driving gear 420 and two driven gears 430.

By arranging the conductive cavity 223 in the insulating rod 221, the area of the connecting member 210 exposed to the outside is reduced, which is beneficial to improve the safety of the overall device.

[0043] In one of the embodiments, the metal connecting plate 211 is provided with a hook 214 away from the insulating rod 221, in the power supply operation, the two hooks 214 are buckled and limited to each other to ensure the stability of the connection of the two metal connecting plates 211, and to avoid the situation that the two metal connecting plates 211 are separated due to poor contact or incorrect operation, resulting in power failure. Specifically, in the power supply operation, after the first driving assembly 400 drives the two sets of the blade assemblies 200 to rotate to the abutting position of the two metal connecting plates 211, the second driving assembly drives the two sets of the blade assemblies 200 to move away from each other, so that the two hooks 214 are buckled and limited to each other, at this time, the two sets of the blade assemblies 200 are relatively fixedly connected, and the two metal connecting plates 211 always abut, so as to ensure that the circuit is always in the power-on state, and to ensure the normal power supply operation of the circuit.

[0044] In one of the embodiments, as shown in Figure 8As shown, the hooks 214 are provided with pressure sensors 215, when the two metal connecting plates 211 abut, the two hooks 214 abut with the metal connecting plates 211 respectively, the pressure sensors 215 are arranged on the end of the hooks 214 abutting with the metal connecting plates 211, whether the hooks 214 abut with the metal connecting plates 211 is detected through the pressure sensors 215, so as to carry out the subsequent fastening operation of the hooks 214, further ensure that the two metal connecting plates 211 always abut, so as to guarantee that the circuit is always in the energized state, and guarantee the normal energization operation of the circuit.

[0045] In one of the embodiments, two bearing frames 120 are slidingly arranged on the base 100, the bearing frames 120 are provided with guide blocks 121, the base 100 is provided with guide grooves 130, the guide blocks 121 are slidingly arranged in the guide grooves 130, so as to realize the sliding of the bearing frames 120 on the base 100.

[0046] Specifically, the two driven gears 430 are arranged on the two bearing frames 120 respectively, when the power-off operation is carried out, the two metal connecting plates 211 are first separated through the driving motor 410, and then the two bearing frames 120 are relatively moved away from each other through the first servo push rods 510. At this time, the driven gears 430 arranged on the two bearing frames 120 respectively also relatively move away from each other and disengage from the meshing with the driving gear 420, that is, the blade assemblies 200 contact and are drivingly connected with the first driving assembly 400, which can effectively avoid the misoperation of the first driving assembly 400 switch, so that the two groups of the blade assemblies 200 are incorrectly combined to cause the power-on, thereby guaranteeing the operation safety of the operating personnel in the circuit maintenance process.

[0047] In one of the embodiments, the high-safety power grid blade device further includes a lifting assembly 600 arranged on the bearing frame 120, the lifting assembly 600 includes a lifting slide rail 610, a sliding frame 620 slidingly connected with the lifting slide rail 610, and a second servo push rod 630, the second servo push rod 630 is arranged on the lifting slide rail 610, the output shaft of the second servo push rod 630 is connected with the sliding frame 620 to drive the sliding frame 620 to slide on the lifting slide rail 610, the blade assembly 200 is connected with the sliding frame 620, and when the blade assembly 200 slides along the lifting slide rail 610 to rise to the second position with the sliding frame 620, the blade assembly 200 is disengaged from the driving connection with the first driving assembly 400.

[0048] Specifically, the sliding frame 620 is connected with the insulating rod 221, and the sliding frame 620 is provided with a collar 640 for the insulating rod 221 to rotate. In the power-off operation, first, the two connecting members 210 are separated by the first driving assembly 400, and then the two sets of the contactor assembly 200 are driven to move away from each other to a position where the two connecting members 210 cannot abut by the first servo push rod 510, and then the sliding frame 620 is pushed up by the second servo push rod 630, the insulating rod 221 rises with the sliding frame 620, the plug-in block 222 at the bottom of the insulating rod 221 is separated from the plug-in hole, the insulating rod 221 is disconnected with the driven gear 430, that is, the contactor assembly 200 is disconnected with the first driving assembly 400, so as to further avoid the misoperation of the first driving assembly 400 to cause the two sets of the contactor assembly 200 to be incorrectly combined to cause power-on, and to ensure the safety of the operator during the circuit maintenance process.

[0049] In one embodiment, the base 100 is provided with distance sensors 700 on both sides for detecting the position of the bearing frame 120, and the distance sensors 700 are respectively connected with the first servo push rod 510 and the second servo push rod 630. Specifically, in the process of driving the bearing frame 120 to move relatively close or far away by the first servo push rod 510, the position of the bearing frame 120 is detected by the distance sensor 700, and the position information of the bearing frame 120 is fed back to the control module (not shown), and the control module sends signals to control the start and stop of the first servo push rod 510 and the second servo push rod 630 according to the position information of the bearing frame 120. Thus, the automatic operation of the first servo push rod 510 and the second servo push rod 630 is realized, and the connection and disconnection of the contactor assembly 200 and the first driving assembly 400 are automatically completed.

[0050] In actual operation, the position of the bearing frame 120 can be pre-set with a power-on position and a power-off position. When the power-on operation is performed, the distance sensor 700 detects the position of the bearing frame 120. If the position of the bearing frame 120 is not at the power-on position, the first servo push rod 510 is started and drives the bearing frame 120 to move to the power-on position. At this time, the driven gear 430 on the bearing frame 120 can be engaged with the driving gear 420, and when the two sets of shutter assemblies 200 are driven by the driven gear 430 to rotate to the first position, the connecting members 210 of the two sets of shutter assemblies 200 can complete the abutment power-on. When the power-off operation is performed, the distance sensor 700 detects the position of the bearing frame 120. If the position of the bearing frame 120 is not at the power-off position, the first servo push rod 510 is started and drives the bearing frame 120 to move to the power-off position. At this time, the driven gear 430 on the bearing frame 120 is separated from the driving gear 420, and the second servo push rod 630 is started again to drive the shutter assembly 200 to separate from the driven gear 430, thereby completely separating the shutter assembly 200 from the first driving assembly 400, avoiding the error start of the first driving assembly 400 to cause power-on, and improving the safety of the operation.

[0051] In one embodiment, the high-safety power grid shutter device further comprises a baffle 800, which is arranged above the base 100. The base 100 and the baffle 800 provide a certain degree of closed operation environment for the first driving assembly 400 and the second driving assembly, which is beneficial to reduce the interference of external factors on the first driving assembly 400 and the second driving assembly, and ensure the normal operation of the first driving assembly 400 and the second driving assembly. Specifically, the bottom of the baffle 800 is provided with a sliding block 810, and the base 100 is provided with a sliding groove 140 for sliding of the sliding block 810. The first driving assembly 400 and the second driving assembly are exposed by sliding the baffle 800, so as to facilitate the disassembly and maintenance of the first driving assembly 400 and the second driving assembly. Further, the two sides of the sliding block 810 are respectively provided with clamping protrusions 811, and the sliding groove 140 is provided with clamping holes 141 corresponding to the positions of the clamping protrusions 811, so as to limit the movement of the sliding block 810 and the sliding groove 140 from other directions of the sliding direction, so that the sliding block 810 can only slide along the length direction of the sliding groove 140, and the stability of the connection between the sliding block 810 and the sliding groove 140 is ensured.

[0052] Further, the baffle 800 is correspondingly provided with an avoiding groove 820 corresponding to the position of the shutter assembly 200, so as to avoid interference and collision between the baffle 800 and the shutter assembly 200 during the sliding process of the baffle 800 on the base 100, and ensure the smooth sliding of the baffle 800 on the base 100.

Various obvious changes and modifications can be made by those skilled in the art without departing from the scope of the present application. It is not necessary to enumerate all the embodiments.
