Description

Technical Field

[0001] This invention relates to the field of power equipment technology, and in particular to a primary and secondary integrated pole-mounted extended device. Background Technology

[0002] Primary and secondary integrated pole-mounted switches are used to promptly disconnect power in the event of a circuit fault. Since these switches are mostly used in exposed environments, and the aging of internal components over long-term use can affect the circuit's open circuit capability, regular inspections are necessary to ensure their proper functioning.

[0003] However, since the switching test is required when inspecting the primary and secondary integrated pole-mounted switches, the power will be cut off, which will affect the lives of residents and even industrial production.

[0004] Therefore, a primary and secondary fusion integrated column-mounted expansion device is needed to solve the above-mentioned technical problems. Summary of the Invention

[0005] This invention addresses the technical problems existing in the prior art by providing a primary and secondary fusion complete column-mounted expansion device.

[0006] The technical solution of this invention to solve the above-mentioned technical problems is as follows: A primary and secondary fusion-type column-mounted expansion device includes a control box, a pole post mounted on the top of the control box, a conductive motor module disposed inside the control box, a conductive post mounted on the conductive motor module, the conductive motor module being used to drive the conductive post to translate, a conductive sleeve sleeved on the outside of the conductive post, an auger connecting the conductive sleeve and the conductive post, a locking component fixed on the outside of the conductive sleeve, and a rectangular opening provided on the side of the control box, with an insulating material penetrating through the interior of the rectangular opening. An insulating sleeve is slidably connected to the control box. An insulating column extends through the interior of the insulating sleeve, and a hexagonal post is provided at the end of the insulating column. The hexagonal post is adapted to the nut screw and the insulating column is adapted to the locking component. The interior of the insulating sleeve has a cylindrical hole and a first sliding cavity. The cylindrical hole, the first sliding cavity, and the insulating column are coaxial. The cross-sectional area of ​​the cylindrical hole is smaller than that of the first sliding cavity. The cross-sectional area of ​​the insulating column is the same as that of the cylindrical hole. A sliding module is provided between the insulating column and the inner wall of the first sliding cavity.

[0007] Preferably, in the above-described primary and secondary fusion-type column-mounted expansion device, the sliding module includes a collar, which is slidably sleeved on the outside of the insulating column. The collar is located inside the first sliding cavity, and the cross-section of the collar is U-shaped. The inner diameter of the collar is the same as the outer diameter of the insulating column. A second sliding cavity is formed between the collar and the insulating column. A second external convex ring is fixedly sleeved on the outside of the insulating column. The second external convex ring is located inside the second sliding cavity and is slidably connected to the second sliding cavity. A positioning unit is provided between the collar and the first sliding cavity.

[0008] Preferably, in the above-mentioned primary and secondary fusion sleeve column expansion device, the positioning unit includes a locking protrusion and two annular locking grooves. The locking protrusion is fixedly sleeved on the outside of the sleeve, and the two annular locking grooves are both disposed on the inner wall of the first sliding cavity.

[0009] Preferably, in the above-mentioned primary and secondary fusion complete column-mounted expansion device, the contact surface cross-section of the locking protrusion and the annular locking groove is arc-shaped, and the locking protrusion is made of elastic material.

[0010] Preferably, in the above-mentioned primary and secondary fusion complete column-mounted expansion device, one side of each of the two annular locking grooves is provided with a transition arc surface.

[0011] Preferably, in the above-mentioned primary and secondary fusion integrated column-mounted expansion device, the end of the insulating column is provided with a handle, the upper side of the insulating sleeve is connected with a spring, the outer side of the control box is hinged with a pull rod, and the upper end of the spring is connected to the middle part of the pull rod.

[0012] Preferably, in the above-mentioned primary and secondary fusion integrated column-mounted expansion device, the rectangular opening is provided with grooves on both sides, the insulating sleeve is fixedly fitted with a first external protruding ring, the two sides of the first external protruding ring are embedded in the groove, and the groove is slidably connected to the first external protruding ring.

[0013] Preferably, in the above-mentioned primary and secondary fusion integrated column-mounted expansion device, the guide column is provided with a second threaded hole and a limiting block, the limiting block is located below the second threaded hole, and the guide sleeve is provided with a first threaded hole.

[0014] The beneficial effects of this invention are as follows: When the device is under maintenance, the pull rod is pulled up and secured with a buckle. The insulating post is pushed to the leftmost end, and the collar is positioned by the positioning unit. The hexagonal post is inserted into the locating screw. By holding the handle at the right end of the insulating post and rotating it, since the second outer convex ring still has sliding space in the second sliding cavity, the locating screw can be removed from the second threaded hole and left in the first threaded hole. At this time, the positioning unit limits the movement of the insulating post to the right, thereby ensuring that the insulating post is firmly locked in the locking part, ensuring that the conductive sleeve can always contact the contact. During maintenance, even if the conductive motor module drives the conductive post to move, the connection between the contact, conductive sleeve, and conductive post is ensured, thereby ensuring the smooth flow of the circuit. Therefore, the device can be operated without power interruption during maintenance. Attached Figure Description

Detailed Implementation

[0026] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0027] like Figure 1 - Figure 9 As shown, the primary and secondary integrated column-mounted extended device includes a control box 2, with a pole post 1 mounted on the top of the control box 2, and a terminal block 3 provided on the top of the pole post 1. Inside the control box 2 is a conductive motor module, on which a conductive post 6 is mounted. The conductive motor module drives the conductive post 6 to move horizontally. When the conductive post 6 contacts the contact point 4, the circuit is connected; otherwise, it is disconnected.

[0028] A conductive sleeve 5 is fitted around the conductive post 6, and conductive grease is applied between the conductive sleeve 5 and the conductive post 6. The conductive post 6 has a second threaded hole 26 and a limiting block 24, with the limiting block 24 located below the second threaded hole 26. The conductive sleeve 5 has a first threaded hole 13. Organic screws 14 are embedded inside the first threaded hole 13 and the second threaded hole 26.

[0029] A locking member 9 is fixed to the outside of the conductive sleeve 5. The locking member 9 is cylindrical. A rectangular opening is provided on the side of the control box 2. An insulating sleeve 10 passes through the inside of the rectangular opening. The insulating sleeve 10 is slidably connected to the control box 2. Specifically, a sliding groove 7 is provided on both sides of the rectangular opening. A first external protruding ring 16 is fixedly sleeved on the outside of the insulating sleeve 10. The two sides of the first external protruding ring 16 are embedded in the inside of the sliding groove 7. The sliding groove 7 is slidably connected to the first external protruding ring 16.

[0030] An insulating column 8 runs through the interior of the insulating sleeve 10. Specifically, the interior of the insulating sleeve 10 is provided with a cylindrical hole 25 and a first sliding cavity 17. The insulating column 8 passes through the cylindrical hole 25 and the first sliding cavity 17. The cylindrical hole 25, the first sliding cavity 17, and the insulating column 8 are coaxial. The cross-sectional area of ​​the cylindrical hole 25 is smaller than that of the first sliding cavity 17. The cross-sectional area of ​​the insulating column 8 is the same as that of the cylindrical hole 25.

[0031] like Figure 3As shown, the end of the insulating post 8 is provided with a hexagonal post 15, which is adapted to the grommet 14. The hexagonal post 15 is used to rotate the grommet 14 to make it rotate, thereby moving forward and backward. The insulating post 8 is adapted to the locking member 9. When the insulating sleeve 10 is at the uppermost stroke position of the slide groove 7, and the conductive sleeve 5 is at its uppermost stroke position, the hexagonal post 15 and the grommet 14 are directly opposite each other, and the insulating post 8 can be directly pushed to insert the hexagonal post 15 into the grommet 14; similarly, when the insulating sleeve 10 and the conductive sleeve 5 are both at their respective lowermost stroke positions, the hexagonal post 15 and the grommet 14 are directly opposite each other.

[0032] When the hexagonal post 15 is inserted into the caliper screw 14, it first enters the locking part 9, and then the end of the insulating post 8 is locked into the locking part 9. Thus, by rotating the handle at the end of the insulating post 8, the hexagonal post 15 and the caliper screw 14 can be rotated.

[0033] A handle is provided at the end of the insulating column 8, and a spring 12 is connected to the upper side of the insulating sleeve 10. A pull rod 11 is hinged to the outside of the control box 2, and the upper end of the spring 12 is connected to the middle of the pull rod 11. When the pull rod 11 is pulled up, the insulating sleeve 10 is at its uppermost position of travel, such as... Figure 1 As shown. When the pull rod 11 is lowered, the insulating sleeve 10 is at its lowest point of travel, as... Figure 2 As shown.

[0034] When the device is in normal use, such as Figure 2 As shown, the conductive sleeve 5 and the conductive post 6 are fixedly connected by a nut screw 14, allowing them to move synchronously. At this time, the insulating post 8 is straightened at its rightmost end, preventing it from touching the conductive sleeve 5.

[0035] During maintenance, the nut screw 14 is disengaged from the second threaded hole 26. At this time, the nut screw 14 is located inside the first threaded hole 13. The conductive sleeve 5 is slidably connected to the conductive post 6, and the upper end of the conductive sleeve 5 is in contact with the contact 4. The conductive sleeve 5 is then inserted into the locking member 9 through the insulating post 8. After the pull rod 11 is pulled up, the insulating sleeve 10 and the insulating post 8 are pulled up by the tension of the spring 12. After the pull rod 11 is pulled up, it is locked by the buckle on the control box 2 housing, thereby causing the insulating post 8 to pull up the locking member 9 and the conductive sleeve 5, ensuring that the conductive sleeve 5 is always in contact with the contact 4. During the test of the conductive motor module, the rise and fall of the conductive post 6 does not affect the circuit's continuity.

[0036] When the device is in normal use, in order to ensure that the insulating post 8 is fixed and does not touch the conductive sleeve 5, and at the same time during maintenance, in order to ensure that the insulating post 8 is firmly inserted into the locking part 9 and to prevent it from being dislodged by external vibration, a relevant positioning structure needs to be set up.

[0037] like Figure 4 - Figure 9 As shown, a sliding module is provided between the insulating post 8 and the inner wall of the first sliding cavity 17. The sliding module includes a collar 20, which is slidably fitted on the outside of the insulating post 8 and located inside the first sliding cavity 17. The collar 20 has a U-shaped cross-section, and its inner diameter is the same as the outer diameter of the insulating post 8. A second sliding cavity 23 is formed between the collar 20 and the insulating post 8. A second external protruding ring 22 is fixedly fitted on the outside of the insulating post 8 and is located inside the second sliding cavity 23. The second external protruding ring 22 is slidably connected to the second sliding cavity 23. A positioning unit is provided between the collar 20 and the first sliding cavity 17. The positioning unit includes a locking protruding ring 21 and two annular locking grooves 18. The locking protruding ring 21 is fixedly fitted on the outside of the collar 20, and the two annular locking grooves 18 are both provided on the inner wall of the first sliding cavity 17. The contact surface between the locking protrusion 21 and the annular locking groove 18 has an arc-shaped cross-section, and the locking protrusion 21 is made of elastic material. To ensure that the locking protrusion 21 can be smoothly locked into the locking groove 18, a transition arc surface 19 is provided on one side of each of the two annular locking grooves 18.

[0038] When the device is in normal use, pull the insulating post 8 to the rightmost end. At this time, the locking protrusion 21 engages in the annular locking groove 18 on the right side, and the collar 20 is fixed in place. However, the insulating post 8 can slide relative to it. This sliding stroke is the length of the second sliding cavity 23. The length of the second sliding cavity 23 should be set as short as possible, ensuring that it is greater than the depth of the second threaded hole 26. At the same time, ensure that the hexagonal post 15 does not contact the conductive sleeve 5 when the second outer protrusion 22 slides to the leftmost end of the second sliding cavity 23. This ensures that the insulating post 8 is fixed in place and does not touch the conductive sleeve 5.

[0039] During maintenance, push the insulating post 8 to the leftmost position. At this time, the locking protrusion 21 engages in the annular locking groove 18 on the left side, and the second outer protrusion 22 slides to the rightmost end of the second sliding cavity 23. The nut screw 14 disengages from the second threaded hole 26 and is located in the first threaded hole 13, and the hexagonal post 15 is fully inserted into the nut screw 14. After the pull rod 11 is pulled up, the conducting sleeve 5 is pulled up by the tension of the spring 12. This ensures that the insulating post 8 is firmly inserted into the locking part 9, preventing it from disengaging due to external vibration.
