Description

Technical Field

[0001] This utility model relates to the field of power equipment manufacturing technology, and in particular to a connecting rod for a switchgear used in a fully enclosed insulated ring network. Background Technology

[0002] The connecting rod in a fully enclosed insulated ring network switchgear is a crucial component. It primarily serves a connecting and transmission function. Within the switchgear, one end of the connecting rod is typically connected to the operating mechanism, while the other end connects to the moving contact of the switch or related transmission components. When the operator operates the operating mechanism, the connecting rod transmits force and movement, enabling the moving contact of the switch to accurately perform opening and closing actions according to predetermined requirements. This achieves circuit connection and disconnection control, ensuring the safe, stable, and reliable operation of the fully enclosed insulated ring network's power transmission. When not in use, the connecting rod is often left unsecured on one side of the switchgear. Without proper securing, it may be mistaken for unrelated debris and moved arbitrarily by staff, easily leading to its loss. If the connecting rod is lost or moved to an unknown location, when the switchgear needs to be restarted, the lack of this critical connecting rod component prevents the operating mechanism from accurately transmitting force and movement to the moving contact, thus hindering the switch's normal opening and closing actions.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0030] Example 1

[0031] Reference Figures 1-8 This is the first embodiment of the present invention. This embodiment provides a switchgear linkage for a fully enclosed insulated ring network, including a main body assembly 100 and a fixing assembly 200, which can be used to fix the linkage when it is not in use.

[0032] Specifically, the main component 100 includes a ring main unit 101, on which a display screen 102 is installed.

[0033] Ring main unit 101 is a fully enclosed insulated ring network switchgear, which is one of the core devices in the power distribution network. It is mainly used for power distribution, control, protection and flexible networking. It is especially suitable for scenarios that require reliable power supply, such as urban power grids, industrial parks and commercial building complexes. Display screen 102 is the human-machine interaction window between the equipment and the operation and maintenance personnel. It is mainly used to display the equipment status, operating parameters and fault information in real time.

[0034] Specifically, the fixing component 200 is set at one end of the ring main unit 101 and includes a fixing member 201. The fixing member 201 includes a fixing frame 2011, which is fixed to one end of the ring main unit 101. A fixing rod 2012 is inserted into the inner wall of the fixing frame 2011. A locking ring 2013 is sleeved on the outer side of the fixing rod 2012. Multiple toothed grooves 2013-1 are opened on the locking ring 2013, and teeth 2014 are provided on the inner wall of the toothed grooves 2013-1.

[0035] There are two sets of fasteners 201, which are fixed to one end of the ring main unit 101 respectively. The fixing rod 2012 is movably connected to the locking ring 2013. A synchronizing rod is connected to the locking ring 2013. The locking ring 2013 can be moved by moving the synchronizing rod.

[0036] When the connecting rod 2031 needs to be used, the limiting position of the tooth groove 2013-1 is released, and then the engaging ring 2013 is moved. The movement of the engaging ring 2013 causes the tooth groove 2013-1 to move. The movement of the tooth groove 2013-1 will separate it from the tooth 2014, and then the connecting rod 2031 can be taken out for use.

[0037] When it is necessary to fix the connecting rod 2031, first put it back on the fixing bracket 2011, and then move the engaging ring 2013. The movement of the engaging ring 2013 causes the tooth groove 2013-1 to move. The movement of the tooth groove 2013-1 will squeeze the teeth 2014 one by one. After the teeth 2014 move to the required position, the teeth 2014 will engage with the tooth groove 2013-1, thereby fixing the connecting rod 2031.

[0038] Example 2

[0039] Reference Figures 1-8 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0040] Specifically, the fixing component 200 also includes a positioning element 202, which includes a support block 2021, and the support block 2021 is fixed to one end of the tooth 2014.

[0041] There are two sets of positioning components 202.

[0042] The support block 2021 moves within the inner wall of the fixed frame 2011.

[0043] By moving the engaging ring 2013, the engaging ring 2013 moves the tooth groove 2013-1, the tooth groove 2013-1 moves and squeezes the tooth 2014, the tooth 2014 moves and drives the support block 2021 to move.

[0044] Specifically, a support rod 2022 is provided at one end of the support block 2021, and two slots 2022-1 are provided on the inner wall of the support rod 2022. A locking block 2023 is provided on the inner wall of the slot 2022-1.

[0045] The movement of the support block 2021 can drive the support rod 2022 to move. The movement of the support rod 2022 causes the slot 2022-1 to press the block 2023. The block 2023 is elastic and can be pressed.

[0046] Specifically, a fixing frame 2024 is provided at one end of the card block 2023, a fixing groove 2024-1 is provided on the inner wall of the fixing frame 2024, a support block 2021 is provided on the inner wall of the fixing groove 2024-1, and one end of the fixing frame 2024 is fixed to one end of the fixing bracket 2011.

[0047] The fixed frame 2024 is used to support the card block 2023. By moving the support rod 2022, the support rod 2022 moves and drives the card slot 2022-1 to squeeze the card block 2023. The movement of the engagement ring 2013 can make the card block 2023 continuously squeezed. When the engagement ring 2013 moves to the required position, the card block 2023 will engage with the card slot 2022-1 to prevent the card block 2023 from moving on its own.

[0048] Specifically, a rotating shaft 2025 is inserted into the inner wall of the support rod 2022. A protective block 2026 is fixed to one end of the rotating shaft 2025. A torsion spring 2027 is sleeved on the outer side of the rotating shaft 2025. One end of the torsion spring 2027 is fixed to one end of the fixing frame 2011, and the other end is fixed to one end of the protective block 2026.

[0049] A synchronous shaft is fixed at one end of the rotating shaft 2025. Rotating one rotating shaft 2025 can drive the synchronous shaft to rotate, and the synchronous shaft drives the other rotating shaft 2025 to rotate, so that the two locking rings 2013 can be simultaneously limited and released.

[0050] When the support rod 2022 is moved, the rotating shaft 2025 will rotate. The rotating shaft 2025 will drive the protective block 2026 to rotate. The rotation of the protective block 2026 will apply a torsional force to the torsion spring 2027. After the engaging ring 2013 is moved to the required position, the spring 2027 will rebound, which will engage the tooth groove 2013-1 with the tooth 2014, thereby completing the fixation of the connecting rod 2031.

[0051] When it is necessary to remove the connecting rod 2031, the protective block 2026 is rotated. The rotation of the protective block 2026 drives the rotating shaft 2025 to rotate. The rotation of the rotating shaft 2025 applies a torsional force to the torsion spring 2027. At this time, the locking block 2023 will separate from the locking groove 2022-1, and then the locking ring 2013 can be taken out to remove the connecting rod 2031 for use.

[0052] Specifically, the fixing component 200 also includes a telescopic component 203, which includes a connecting rod 2031. The connecting rod 2031 is inserted into the inner wall of the fixing frame 2011. A threaded rod 2032 is inserted into the inner wall of the connecting rod 2031. A connecting shaft 2033 is sleeved on the outer side of the threaded rod 2032. There are three connecting shafts 2033. Each connecting shaft 2033 has a sliding strip 2034 on its surface. Each connecting shaft 2033 has a sliding groove 2033-1 on its inner wall. The sliding strip 2034 slides in the sliding groove 2033-1.

[0053] A groove corresponding to the sliding bar 2034 is also provided on the inner wall of the connecting rod 2031.

[0054] When the connecting rod 2031 is removed and needs to be used, the threaded rod 2032 is rotated. The rotation of the threaded rod 2032 will drive the connecting shaft 2033 to rotate. The rotation of the connecting shaft 2033 will drive the sliding bar 2034 to slide in the groove on the inner wall of the connecting rod 2031. The movement of the connecting shaft 2033 will also drive the sliding bar 2034 to slide in the inner wall of the sliding groove 2033-1. By rotating one connecting shaft 2033, the other two connecting shafts 2033 can be driven to move synchronously to the extension position.

[0055] Example 3

[0056] Reference Figures 7-8 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0057] Specifically, a first telescopic rod 2035 is provided on the inner wall of the connecting shaft 2033. The first telescopic rod 2035 is rotatable on the inner wall of the connecting shaft 2033. A positioning rod 2036 is sleeved on the outer side of the first telescopic rod 2035 and is fixed to the inner wall of the connecting shaft 2033.

[0058] The rotation of the connecting shaft 2033 will drive the first telescopic rod 2035 to rotate, and the rotation of the first telescopic rod 2035 will drive the positioning rod 2036 to rotate.

[0059] Specifically, the positioning rod 2036 is threadedly connected to the first telescopic rod 2035, and the second telescopic rod 2037 is sleeved on the outside of the positioning rod 2036.

[0060] The rotation of the positioning rod 2036 can drive the connecting shaft 2033 to move. The movement of the connecting shaft 2033 causes the sliding strip 2034 to slide in the groove on the inner wall of the connecting rod 2031. The rotation of the positioning rod 2036 will also drive the second telescopic rod 2037 to rotate.

[0061] Specifically, the inner wall of the connecting shaft 2033 is provided with a threaded groove 2033-2, and the connecting shaft 2033 is threadedly connected to the second telescopic rod 2037.

[0062] The rotation of the second telescopic rod 2037 causes the threaded groove 2033-2 to rotate, and the threaded groove 2033-2 causes the connecting shaft 2033 to move.

[0063] Specifically, a handle 2038 is fixed to the top of the threaded rod 2032.

[0064] By rotating the handle 2038, the threaded rod 2032 will be driven to rotate.

[0065] In use, when it is necessary to fix the connecting rod 2031, first place it on the fixing bracket 2011, and then move the synchronizing rod. The movement of the synchronizing rod drives the engagement ring 2013 to move, which in turn drives the tooth groove 2013-1 to move. The movement of the tooth groove 2013-1 will squeeze the teeth 2014 one by one. The movement of the teeth 2014 will drive the support block 2021 to move, which in turn drives the support rod 2022 to move. The movement of the support rod 2022 will cause the locking groove 2022-1 to engage the locking block 2031. 23 is squeezed. The movement of the locking ring 2013 can continuously squeeze the locking block 2023. The movement of the support rod 2022 will also drive the rotating shaft 2025 to rotate. The rotating shaft 2025 drives the protective block 2026 to rotate. The rotation of the protective block 2026 can apply a torsional force to the torsion spring 2027. After the locking ring 2013 is moved to the required position, the rebound force of the torsion spring 2027 can make the tooth groove 2013-1 engage with the tooth 2014, thereby completing the fixation of the connecting rod 2031.

[0066] When it is necessary to remove the connecting rod 2031, the protective block 2026 is rotated. The rotation of the protective block 2026 drives the rotating shaft 2025 to rotate. The rotation of the rotating shaft 2025 applies a torsional force to the torsion spring 2027. At this time, the locking block 2023 will separate from the locking groove 2022-1, and then the locking ring 2013 can be taken out to remove the connecting rod 2031 for use.

[0067] When the connecting rod 2031 is removed and needs to be used, the handle 2038 is rotated. The rotation of the handle 2038 will drive the threaded rod 2032 to rotate, which in turn will drive the connecting shaft 2033 to rotate. The rotation of the connecting shaft 2033 will cause the sliding strip 2034 to slide in the groove on the inner wall of the connecting rod 2031. The rotation of the connecting shaft 2033 will also drive the first telescopic rod 2035 to rotate, which in turn will drive the positioning rod 2036 to rotate. The rotation of the connecting shaft 2033 will also drive the sliding strip 2034 to slide in the inner wall of the sliding groove 2033-1. The positioning rod 2036 can drive the other connecting shafts 2033 to move. The rotation of the positioning rod 2036 will also drive the second telescopic rod 2037 to rotate, which in turn will drive the threaded groove 2033-2 to rotate. The threaded groove 2033-2 allows the connecting shaft 2033 to move to its extended position.
