[0002] 6KV high-voltage distribution cabinet (or switch cabinet) is a high-voltage power equipment, mainly including shell, partition and pressure relief device, busbar room, circuit breaker room, cable room and grounding mechanism (grounding switch), etc. Among them, the main function of the grounding mechanism is to ensure that the high-voltage distribution cabinet can quickly cut off the power supply when a fault occurs, so as to prevent major accidents such as electric shock and fire. When the high-voltage equipment and lines are overhauled, the equipment is grounded to protect personal safety. At the same time, artificial grounding can also be caused to meet the protection requirements. For example, the grounding switch is configured next to the isolating switch on both sides of the circuit breaker, which plays the role of grounding on both sides of the circuit breaker during maintenance.

[0003] In the related technologies, considering safety factors and efficiency issues, many enterprises gradually adopt robots to replace manual separation and combination of ground knife mechanisms, which can not only improve work efficiency and accuracy, but also ensure personnel safety and reduce maintenance costs. However, it is difficult for the current robot arm to automatically and accurately dock with the ground knife mechanism, resulting in inadequate operation of the ground knife mechanism, causing equipment failure, and even safety accidents in serious cases.

[0032] like Figures 1 to 4 As shown, an embodiment of the utility model provides an adapter 100, which is applied to a high-voltage switch cabinet 200. The high-voltage switch cabinet 200 is provided with a cabinet body 201 and a ground knife mechanism 202. The adapter 100 includes an adapter sleeve 10 and a fixing assembly 20. The adapter sleeve 10 is provided with a first connecting portion 11 and a second connecting portion 12 at two axial ends thereof. The first connecting portion 11 is used to penetrate into the cabinet body 201, be sleeved on and fixed to the outer periphery of the operating rod of the ground knife mechanism 202, and the second connecting portion 12 is used to penetrate out of the cabinet body 201, be sleeved on and fixed in the sleeve of the robot arm 300; the fixing assembly 20 is detachably connected to the adapter sleeve 10, and the fixing assembly 20 is fixed on the cabinet body 201.

[0033] Based on the above technical solution, the ground knife mechanism 202 is arranged inside the cabinet 201, and the robot needs to operate the ground knife mechanism 202 outside the cabinet 201, so the robot arm 300 needs to extend into the cabinet 201 to match and fix with the ground knife mechanism 202, but the operating rod structure of the ground knife mechanism 202 is relatively complex, and it is difficult for the robot arm 300 to automatically align with the operating rod of the ground knife mechanism 202. In this embodiment, the adapter 100 is applied to the high-voltage switch cabinet 200. Specifically, the adapter sleeve 10 is connected to the cabinet 201 through the fixing assembly 20, and the first connecting portion 11 of the adapter sleeve 10 is inserted into the cabinet 201 and is sleeved and fixed on the outer periphery of the operating rod of the ground knife mechanism 202, so that the ground knife mechanism 202 can be connected and fixed with one end of the adapter sleeve 10, and the second connecting portion 12 of the adapter sleeve 10 is inserted out of the cabinet 201 and is sleeved and fixed in the sleeve of the robot arm 300, so that the robot arm 300 can be connected and fixed with the other end of the adapter sleeve 10. In this embodiment, the operating rod of the ground knife mechanism 202 is extended outside the cabinet 201 by using the adapter 100, and the operating rod of the ground knife mechanism 202 is replaced by the second connecting part 12 that can be matched and fixed with the robot arm 300. In this way, the robot arm 300 does not need to extend into the cabinet 201 to be directly connected and fixed to the ground knife mechanism 202, but is indirectly connected and fixed to the ground knife mechanism 202 through the adapter 100. The robot arm 300 rotates to make the adapter 100 interlock with the ground knife mechanism 202, thereby realizing the opening and closing operation of the ground knife mechanism 202.

[0034] As an implementation method, Figure 4 and Figure 5 As shown, the adapter sleeve 10 includes a first sleeve 14 and a second sleeve 15 , the first connecting portion 11 is provided on the first sleeve 14 , the second connecting portion 12 is provided on the second sleeve 15 , and the first sleeve 14 and the second sleeve 15 are detachably connected.

[0035] Specifically, the adapter sleeve 10 of this embodiment is a segmented sleeve, the first sleeve 14 (right sleeve) penetrates into the cabinet 201, the second sleeve 15 (left sleeve) penetrates out of the cabinet 201, the first connection portion 11 of the first sleeve 14 is sleeved and fixed on the outer periphery of the operating rod of the ground cutter mechanism 202, and the second connection portion 12 of the second sleeve 15 is sleeved and fixed with the sleeve of the robot arm 300. According to actual needs, two sleeves of different specifications or lengths can be selected for combination to adapt to different sizes of ground cutter mechanisms 202 and robot arms 300, thereby enhancing the versatility of the adapter sleeve 10.

[0036] In this embodiment, the first sleeve 14 and the second sleeve 15 may be connected and fixed in a threaded manner, for example, matching threads are machined on the inner wall of the first sleeve 14 and the outer wall of the second sleeve 15, and the threads are engaged with each other by rotating the two sleeves, thereby achieving fixation. The first sleeve 14 and the second sleeve 15 may also be connected and fixed in a wedge-shaped manner, where a wedge-shaped section is made on the first sleeve 14, the second sleeve 15 is inserted into the wedge-shaped section and rotated at a certain angle, and the wedges are engaged with each other to achieve fixation.

[0037] As an implementation method, Figure 4 and Figure 5 As shown, the adapter sleeve 10 includes a pin 13, a first sleeve 14 is provided with a first mounting hole 16, and a second sleeve 15 is provided with a second mounting hole 17. The second sleeve 15 is sleeved in the first sleeve 14, and the pin 13 is passed through the first mounting hole 16 and the second mounting hole 17 to fix the second sleeve 15 on the first sleeve 14.

[0038] Specifically, this embodiment provides a pin connection method, which is a simple and direct fixing method that does not require complicated installation steps or tools. It only requires inserting the second sleeve 15 into the first sleeve 14, aligning the first mounting hole 16 with the second mounting hole 17, and then passing the pin 13 through the first mounting hole 16 and the second mounting hole 17 to achieve the fixation of the two sleeves.

[0039] The two sleeves of this embodiment are connected by a pin shaft. On the one hand, the pin shaft 13 can play an anti-over-torque role. During the process of the robot arm 300 performing the ground knife operation, if the torque is too large or the operation is improper, the ground knife mechanism 202 will be damaged. However, when the pin shaft 13 can be disconnected first when subjected to excessive torque, it actually plays the role of a "fuse", thereby preventing the robot arm 300 from continuing to apply excessive torque to the ground knife mechanism 202, effectively protecting the ground knife mechanism 202 from damage, and providing more safety guarantees for the cabinet 201. By introducing the anti-over-torque design of the pin shaft 13 in this embodiment, the connection between the adapter sleeve 10 and the ground knife mechanism 202 connected to it and the robot arm 300 becomes more reliable.

[0040] On the other hand, the pin connection has a relatively high connection strength, especially when an interference fit is adopted between the pin 13 and the mounting hole, which can ensure that the sleeve will not become relatively loose or relatively displaced when subjected to external loads, thereby ensuring the stability and reliability of the connection between the two sleeves.

[0041] As an implementation method, Figure 2 and Figure 3 As shown, the inner wall of the first connecting portion 11 is provided with a spline structure 18 extending in the axial direction, and the spline structure 18 is used for being sleeved on the operating rod of the ground knife mechanism 202 .

[0042] Specifically, in practical applications, a circle of splines or tooth structures are usually provided on the outer periphery of the operating rod of the ground knife mechanism 202. Based on this, in this embodiment, a spline structure 18 is provided on the inner wall of the first connecting portion 11, which can match the splines of the operating rod of the ground knife mechanism 202. The dense tooth shape of the spline matches the corresponding groove on the operating rod, providing high-precision positioning and connection, reducing the shaking and displacement of the operating rod during the connection process, thereby improving the stability of the connection.

[0043] It is understandable that the spline structure 18 can effectively transmit torque, ensuring that the operating rod of the ground knife mechanism 202 obtains sufficient power when rotating. At the same time, the dense tooth design of the spline increases the contact area, so that the operating rod can still maintain a stable connection state when bearing a large load. The spline is usually made of wear-resistant material, has good wear resistance, can resist wear during long-term use, and extend the service life of the connection parts.

[0044] As an implementation method, Figure 2 As shown, the outer wall of the second connecting portion 12 is provided with a prism structure 19 extending in the axial direction, and the prism structure 19 is used to be sleeved in the sleeve of the robot arm 300 .

[0045] Specifically, the inner hole of the sleeve of the robot arm 300 is usually a regular polygon, and the prism structure 19 on the outer wall of the second connection part 12 can match the inner hole of the sleeve of the robot arm 300. In this way, when the robot arm 300 is docked with the second connection part 12, the inner hole of the sleeve can be easily inserted into the prism structure 19, and the two can be connected and fixed. Of course, the regular polygon inner hole and the prism structure 19 are universal and can adapt to robot arms 300 of different sizes and specifications.

[0046] Exemplarily, the inner hole of the sleeve of the robot arm 300 is a regular hexagon, and the outer wall of the second connecting part 12 is provided with a regular hexagonal prism structure 19. The matching design of the prism structure 19 and the regular hexagonal inner hole makes it difficult for the adapter sleeve 10 to shake or misalign during rotation.

[0047] In actual application, a spline structure 18 is provided on the inner wall of the first connecting part 11, and a prismatic structure 19 is provided on the outer wall of the second connecting part 12. The spline structure 18 is fixed with the spline of the operating rod of the ground knife mechanism 202 in the cabinet 201, and the prismatic structure 19 is fixed with the sleeve of the robot arm 300 outside the cabinet 201. The robot arm 300 rotates so that the adapter 100 interlocks with the ground knife mechanism 202, thereby realizing the opening and closing operation of the ground knife mechanism 202.

[0048] As an implementation manner, the first sleeve 14 is provided with a plurality of first mounting holes 16 along its axial direction, and the second sleeve 15 is provided with a plurality of second mounting holes 17 along its axial direction, and each first mounting hole 16 corresponds to each second mounting hole 17 one by one.

[0049] Specifically, in this embodiment, a plurality of first mounting holes 16 and a second mounting hole 17 corresponding to each other are respectively arranged on the first sleeve 14 and the second sleeve 15. A plurality of pins 13 can be used to fix the two sleeves, or one pin 13 can be selected according to actual needs. During the installation process, the relative position between the first sleeve 14 and the second sleeve 15 is fine-tuned by adjusting the position of the pin 13 in different mounting holes, so as to form a sleeve structure similar to a telescopic sleeve with adjustable length.

[0050] As an implementation method, Figure 6 As shown, the adapter 100 includes a first bearing 30 and a second bearing 40 . The first bearing sleeve 30 is arranged on the outer periphery of the first sleeve 14 , the second bearing 40 is sleeved on the outer periphery of the second sleeve 15 , and the fixing assembly 20 is sleeved on the outer peripheries of the first bearing 30 and the second bearing 40 .

[0051] Specifically, the outer periphery of the first sleeve 14 and the outer periphery of the second sleeve 15 are both provided with bearings, so that the first sleeve 14 and the second sleeve 15 can achieve smooth rotation in the direction of their axis to ensure the rotational coaxiality of the first sleeve 14 and the second sleeve 15. The bearings can not only provide rotational flexibility, but also effectively support the first sleeve 14 and the second sleeve 15 to ensure that they remain stable when subjected to external loads. Among them, the first bearing 30 can adopt a deep groove ball bearing, the inner and outer rings of the deep groove ball bearing are almost parallel, and can withstand large radial and axial loads. The second bearing 40 can adopt an angular contact bearing, which can withstand high radial and axial loads and maintain a stable operating state. The load is shared by multiple rolling elements, reducing the stress concentration effect.

[0052] Exemplarily, a deep groove ball bearing is installed on the outer periphery of the first sleeve 14 , and two angular contact bearings are installed on the outer periphery of the second sleeve 15 .

[0053] As an implementation method, Figure 6 or Figure 7 As shown, the fixing assembly 20 includes an adjusting nut 23, a first mounting plate 21 and a second mounting plate 22. The first mounting plate 21 is sleeved on the outer periphery of the first bearing 30 and the second bearing 40. The second mounting plate 22 is attached to the cabinet body 201, and the second mounting plate 22 is fixed to the first mounting plate 21 by the adjusting nut 23. The adjusting nut 23 is used to fix the second mounting plate 22 to the cabinet body 201.

[0054] Specifically, the first mounting plate 21 is sleeved on the outer circumference of the first bearing 30 and the second bearing 40, and is used to fix the adapter sleeve 10 and the bearing member. The second mounting plate 22 is attached to the cabinet 201. The second mounting plate 22 can be quickly fixed to the cabinet 201 by adjusting the nut 23, and can be easily disassembled when needed. Due to the combined design of the adjusting nut 23 and the mounting plate, the fixing assembly 20 can be used for different types of cabinets 201, which increases versatility.

[0055] As an implementation manner, the fixing assembly 20 includes a rubber pressing plate 24 , and the rubber pressing plate 24 is disposed on a side of the second mounting plate 22 facing the cabinet 201 .

[0056] Specifically, the rubber pressure plate 24, as an elastic material, has good buffering and shock absorbing properties. The surface friction coefficient of the rubber pressure plate 24 is relatively large, and the friction between the rubber pressure plate 24 and the cabinet 201 is also relatively large. By adjusting the nut 23 to fix the second mounting plate 22 to the cabinet 201 and pressing the rubber pressure plate 24 toward the cabinet 201, the fixing assembly 20 can be effectively prevented from sliding or shifting relative to the cabinet 201, thereby improving the stability of the structure of the adapter 100.

[0057] Second, as Figure 8 As shown, an embodiment of the utility model provides a high-voltage switch cabinet 200 , which includes a cabinet body 201 and an adapter 100 , wherein the adapter 100 is installed on the cabinet body 201 .

[0058] Specifically, the high-voltage switch cabinet 200 of this embodiment uses the adapter 100 to extend the operating rod of the ground knife mechanism 202 outside the cabinet body 201. The robot arm 300 does not need to extend into the cabinet body 201 to be directly connected and fixed to the ground knife mechanism 202, but is indirectly connected and fixed to the ground knife mechanism 202 through the adapter 100. The robot arm 300 rotates to make the adapter 100 interlock with the ground knife mechanism 202, thereby realizing the opening and closing operation of the ground knife mechanism 202.

[0059] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
