Description

Technical Field

[0001] The utility model relates to the technical field of maintenance of an isolating switch operating mechanism box, in particular to a maintenance auxiliary tool for an isolating switch operating mechanism box. Background Art

[0002] The isolating switch operating mechanism box is used to control the opening and closing of the isolating switch. When the isolating switch operating mechanism box cuts off the path of the isolating switch circuit, the circuit is separated from the power supply to cut off the power supply of the circuit. This function is very important for the maintenance, inspection and troubleshooting of the power supply system. It can ensure that the circuit is in a safe state when performing these operations to avoid current from causing harm to maintenance personnel or damage to equipment.

[0003] Usually, there is a mechanical transmission mechanism inside the isolating switch operating mechanism box, and the isolating switch is set on one side of the isolating switch operating mechanism box through a support. A transmission rod connected to the mechanical transmission mechanism extends from the top of the isolating switch operating mechanism box, and the top of the transmission rod is connected to the isolating switch. When the transmission rod rotates in the positive and negative directions, the isolating switch can be controlled to be in the open or closed state.

[0004] Since the isolating switch operating mechanism box is usually placed outdoors, as the external environment changes, the isolating switch operating mechanism box is prone to failure due to rain erosion and wind and sand wear. Therefore, it is currently possible to add relevant sensors to the transmission rod to judge whether the transmission rod is working reliably. For example, the Chinese utility model patent with application number 201921131840.6 provides a torque overvalue alarm device for the isolating switch operating mechanism box, which uses the torque detection sensor to determine whether the torque data value is abnormal to perform intelligent alarm.

[0005] However, the reliability of electronic sensors when used outdoors is low, so operators are required to inspect and maintain the isolating switch operating mechanism box; during the maintenance process, the transmission rod will be separated from the isolating switch operating mechanism box. At this time, the top of the transmission rod is connected to the isolating switch, and the transmission rod shakes unstably, which on the one hand affects the maintenance work and reduces the maintenance efficiency, and on the other hand, it is easy to damage the isolating switch and reduce its service life. Therefore, the maintenance of the isolating switch operating mechanism box cannot meet actual needs. Utility Model Content

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0025] Refer to Figure 1 , the top of the disconnector operating mechanism box 10 is in transmission connection with the drive rod 20 through a flange 50. A strut 30 is arranged on one side of the disconnector operating mechanism box 10. A disconnector is arranged at the top of the strut 30, and the top of the drive rod 20 is connected to the disconnector. During use, the disconnector operating mechanism box 10 controls the rotation of the drive rod 20, thereby controlling the opening and closing of the disconnector at its top.

[0026] Embodiment 1

[0027] Refer to Figures 1 to 3 , this embodiment provides a maintenance auxiliary tool for a disconnector operating mechanism box, including an auxiliary connection member 40 connecting the drive rod 20 and the strut 30, so that when the disconnector operating mechanism box 10 is maintained, the drive rod 20 is fixed on the periphery of the strut 30 by using the auxiliary connection member 40 to prevent the drive rod 20 from shaking.

[0028] During the actual maintenance process, after disassembling the transmission rod 20 from the flange 50 at the top of the disconnector operating mechanism box 10, it can be separated, which facilitates the maintenance of the disconnector operating mechanism box 10. At the same time, it can also ensure the service life of the disconnector and meet the actual maintenance requirements.

[0029] Specifically, the auxiliary connecting member 40 can be selectively connected to the transmission rod 20 and the support column 30 by means of tying, magnetic attraction, bonding or clamping. Preferably, the auxiliary connecting member 40 is clamped to the transmission rod 20, and the auxiliary connecting member 40 is detachably connected to the support column 30. At the same time, the diameter of the support column 30 is usually selected to be twice or more the diameter of the transmission rod 20.

[0030] Specifically, the auxiliary connecting member 40 includes a connecting base plate 41, a transmission rod clamping member 42 and a support column clamping member 43. Among them, the connecting base plate 41 cooperates with the transmission rod clamping member 42 to connect the transmission rod 20, and the connecting base plate 41 cooperates with the support column clamping member 43 to connect the support column 30.

[0031] Thus, the transmission rod 20 is kept stable relative to the support column 30 to avoid shaking. At the same time, the transmission rod 20 can also be supported by the transmission rod clamping member 42, reducing the influence of the self-weight of the transmission rod 20 on the disconnector.

[0032] The transmission rod clamping member 42 can be used as a clamping member to be clamped to the transmission rod 20. Preferably, the transmission rod clamping member 42 can also be selected as a U-shaped structure. The transmission rod clamping member 42 is sleeved outside the transmission rod 20, and the transmission rod clamping member 42 cooperates with the connecting base plate 41 to realize the clamping of the transmission rod 20. The disassembly is simple and convenient, reducing the impact on the maintenance efficiency.

[0033] During actual use, first disassemble the support column clamping member 43 from the connecting base plate 41. Then, after sleeving the support column clamping member 43 outside the support column 30, connect the support column clamping member 43 to the connecting base plate 41 to keep the auxiliary connecting member 40 stably connected to the support column 30.

[0034] Subsequently, disassemble the transmission rod clamping member 42 from the connecting base plate 41. Then, after sleeving the transmission rod clamping member 42 outside the transmission rod 20, finally connect the transmission rod clamping member 42 to the connecting base plate 41 to connect the connecting base plate 41 to the transmission rod 20, so as to ensure that the transmission rod 20 can still keep its position fixed relative to the support column 30 after being disassembled from the disconnector operating mechanism box 10.

[0035] Further explanation, the connecting base plate 41 includes an arc section 61 and a strip section 62. One end of the strip section 62 is connected to one end of the arc section 61, and the other end of the strip section 62 is connected to the transmission rod clamping member 42.

[0036] Correspondingly, the support column clamping member 43 is an arc structure, and the support column clamping member 43 and the arc section 61 cooperate to form a clamp for the support column 30.

[0037] The transmission rod clip 42 is of a U-shaped structure, and the transmission rod clip 42 cooperates with the strip segment 62 to form a clamp for the transmission rod 20.

[0038] One end of the support clip 43 is connected to the corresponding end of the arc segment 61 through a connecting bolt 60, and the other end of the support clip 43 is connected to the strip segment 62 through a connecting bolt 60. The connecting bolt 60 on the strip segment 62 is located between the transmission rod clip 42 and the arc segment 61, and at the same time, the arc segment 61 and the transmission rod clip 42 are on the same side.

[0039] Further preferably, connecting threads are provided at both ends of the transmission rod clip 42. When connecting, the end of the transmission rod clip 42 passes through the connecting base plate 41 and is detachably connected through a connecting nut.

[0040] Obviously, the above-described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
