Abstract
Description
Technical Field
[0001] This invention relates to the field of disconnector technology, and specifically to a device for recovering live foreign objects from a double-column disconnector. Background Technology
[0002] In recent years, the problems of foreign objects accumulating or entangled on disconnecting switches have become increasingly prominent in posing a threat to substation operating equipment. The power grid system has experienced multiple incidents of equipment tripping or temporary shutdowns caused by foreign objects hanging on disconnecting switches.
[0003] CN111816490A discloses an outdoor low-voltage enclosed load disconnector. By encapsulating all components of the disconnector within a housing, it protects the metal parts of the disconnector and effectively prevents foreign objects from contacting it. However, it is difficult to install and maintain during use, and it requires high-temperature resistance from the components encapsulated within the housing. Due to the lack of ventilation inside the housing, heat dissipation is greatly reduced, and it is also impossible to collect and handle foreign objects that fall onto the disconnector, posing a significant safety hazard. It is extremely unsuitable for handling foreign objects in double-column disconnectors. Therefore, there is an urgent need for those skilled in the art to design a device suitable for handling live foreign objects in double-column disconnectors. Summary of the Invention
[0004] The problem this invention aims to solve is to provide a device for collecting foreign objects on disconnecting switches, preventing them from falling off, and allowing for safe and easy removal of the foreign objects when the collection area is full. When foreign objects slide off the disconnecting switch to the foreign object collection insulating part, they are collected by the foreign object storage extension part and concentrated in the foreign object collection bag at the bottom of the device. When the foreign object collection is full, the foreign object can be removed by taking out the foreign object collection insulating part and removing the storage bag from the hook. This device can prevent foreign objects from falling off, effectively recover foreign objects, and improve operating efficiency.
[0005] To address the aforementioned problems, this invention provides a dual-column disconnector switch live foreign object recovery device, comprising a platform fixing component, a platform support component, and a foreign object collection device. The platform fixing component has a platform support component at its bottom end, which is rotatably and separably connected to it, effectively ensuring the stability of the connection between the platform fixing component and the platform support component, while facilitating installation and disassembly. Both ends of the platform fixing component are provided with foreign object collection devices and are hinged to them.
[0006] The foreign object collection device has three parts, including a foreign object collection insulating part located at the inner end of the central opening of the platform support component and foreign object storage extension parts symmetrically located at both ends of the foreign object collection device. The foreign object storage extension parts have a V-shaped structure.
[0007] Preferably, the platform fixing assembly includes a first platform fixing insulating plate and a second platform fixing insulating plate. A threaded rod is fixedly provided on the side end of the first platform fixing insulating plate, and a threaded slot is provided on the inner end of the second platform fixing insulating plate. The threaded rod is rotatably inserted into the threaded slot, which can effectively ensure the overall fixation of the platform fixing assembly, while facilitating installation and disassembly.
[0008] Preferably, the outer edges of the first platform fixing insulation plate and the second platform fixing insulation plate are provided with mirror-shaped U-shaped grooves, and the center of the first platform fixing insulation plate and the second platform fixing insulation plate are provided with supporting threaded grooves.
[0009] Preferably, the platform support assembly includes a platform support rod, the top of which is provided with a threaded protrusion, which is rotatably inserted into a support threaded groove.
[0010] Preferably, the foreign object storage extension includes a support connecting plate, an extension support insulating plate, a hook, and a storage bag. One end of the support connecting plate is hinged to the platform fixing insulating plate, and the other end of the support connecting plate is hinged to the extension support insulating plate. A collection groove and a hook groove are provided at the connection between the support connecting plate and the extension support insulating plate. The hook passes through the hook groove and extends to both ends. The two ends of the storage bag are respectively sleeved on the hook parts at both ends of the hook, thereby placing the storage bag at the lower end of the collection groove.
[0011] Preferably, the supporting connecting plate and the platform fixing insulating plate are folded outwards, and the included angle at the connection between the supporting connecting plate and the platform fixing insulating plate is 180°-225°.
[0012] Preferably, the supporting connecting plate and the extended supporting insulating plate are folded inward, and the included angle at the connection between the supporting connecting plate and the extended supporting insulating plate is 0°-70°.
[0013] Preferably, the foreign matter collection insulation part is an insulated bottle structure.
[0014] The advantages of using the above structure are as follows:
[0015] The platform fixing component of this invention is equipped with foreign object collection devices at both ends and hinged to them. These devices can collect foreign objects falling from the disconnect switch from multiple directions, thus achieving comprehensive collection. The foreign object collection device comprises three parts: a foreign object collection insulating part located inside the central opening of the platform support component, and foreign object storage extension parts symmetrically located at both ends of the device. The insulating part collects foreign objects falling from the center of the disconnect switch, while the V-shaped storage extension parts fully cover the halfway point where the foreign object lands. The device collects foreign objects that fall from the upper corners of the disconnecting switch, as well as those that do not fall into the insulating part, by sliding them into the extended part for collection. This allows the foreign objects to be concentrated at the bottom of the device. When the collection is almost full, the insulating part can be removed from the U-shaped groove between the first and second platform fixed insulating plates. The foreign objects can then be removed by taking the collection bag off the hook. This method is safe and convenient, greatly reducing the risk of foreign objects falling and causing a short circuit to the equipment during the handling of foreign objects. This ensures reliable recovery of foreign objects when handling disconnecting switches under energized conditions. Attached Figure Description

Detailed Implementation
[0020] The present invention will be further explained and described below with reference to the accompanying drawings and embodiments.
[0021] like Figures 1-3As shown, a dual-column disconnector switch live foreign object recovery device includes a platform fixing component 1, a platform support component 2, and a foreign object collection device 3. The platform fixing component 1 has a platform support component 2 at its bottom end and is rotatably and separably connected to it. This rotatable and separable connection can effectively ensure the fixation of the connection between the platform fixing component 1 and the platform support component 2, while facilitating installation and disassembly. Both ends of the platform fixing component 1 are provided with foreign object collection devices 3 and are hinged to them. The foreign object collection devices 3 can collect foreign objects falling from the disconnector switch from multiple directions, thereby achieving comprehensive collection of foreign objects.
[0022] The foreign object collection device 3 comprises three parts: a foreign object collection insulating part 301 located at the inner end of the central opening of the platform support component 2, and foreign object storage extension parts 302 symmetrically located at both ends of the foreign object collection device 3. The foreign object collection insulating part 301 has an insulating bottle structure and can collect foreign objects falling from the center of the disconnect switch. The foreign object storage extension parts 302 have a V-shaped structure and can fully cover the landing radius of the foreign object, collecting foreign objects falling from the corners of the disconnect switch as well as those that do not fall in. Foreign objects in the collecting insulation part 301 slide into the foreign object collection extension part 302 for collection, so that the foreign objects can be concentrated at the bottom of the device. When the foreign objects are about to be collected, the foreign object collecting insulation part 301 can be removed from the U-shaped groove 105 between the first platform fixed insulation plate 101 and the second platform fixed insulation plate 102. The foreign objects can be removed by removing the collection bag 306 from the hook 305. This is safe and convenient, and greatly reduces the risk of foreign objects falling and causing a short circuit to the equipment grounding during foreign object handling. This enables reliable recovery of foreign objects when handling foreign objects in the disconnecting switch under energized conditions.
[0023] The platform fixing assembly 1 includes a first platform fixing insulating plate 101 and a second platform fixing insulating plate 102. A threaded rod 103 is fixedly provided on the side end of the first platform fixing insulating plate 101, and a threaded slot 104 is provided on the inner end of the second platform fixing insulating plate 102. The threaded rod 103 is rotatably inserted into the threaded slot 104, which can effectively ensure the overall fixation of the platform fixing assembly 1, and at the same time facilitate installation and disassembly.
[0024] The outer edges of the first platform fixing insulation plate 101 and the second platform fixing insulation plate 102 are both provided with mirror-shaped U-shaped grooves 105. The center of the first platform fixing insulation plate 101 and the second platform fixing insulation plate 102 is provided with a support threaded groove 106. The platform support assembly 2 includes a platform support rod 201. The top of the platform support rod 201 is provided with a threaded protrusion 202. The threaded protrusion 202 is rotatably inserted into the support threaded groove 106. The platform support rod 201 provides support for the platform fixing assembly 1.
[0025] The foreign object storage extension section 302 includes a support connecting plate 303, an extension support insulating plate 304, a hook 305, and a storage bag 306. One end of the support connecting plate 303 is hinged to the platform fixed insulating plate via a hinge 307, and the other end of the support connecting plate 303 is hinged to the extension support insulating plate 304 via a hinge 307. A collection groove 308 and a hook groove 309 are provided at the connection between the support connecting plate 303 and the extension support insulating plate 304. The hook 305 passes through the hook groove 309 and extends to both ends. The two ends of the storage bag 306 are respectively sleeved on the hook portions 310 at both ends of the hook 305, thereby placing the storage bag 306 at the lower end of the collection groove 308.
[0026] The supporting connecting plate 303 and the platform fixed insulating plate are folded outwards, and the angle between the supporting connecting plate 303 and the platform fixed insulating plate is 180°-225°. The supporting connecting plate 303 and the extended supporting insulating plate 304 are folded inwards, and the angle between the supporting connecting plate 303 and the extended supporting insulating plate 304 is 0°-70°. With the above structure, the area of the foreign object collection device 3 when collecting foreign objects can be greatly increased, so that it can fully cover the area where the foreign object falls.
[0027] To facilitate understanding of the above technical solutions of the present invention, the following detailed description of the above technical solutions of the present invention will be provided through specific usage methods.
[0028] The specific installation and usage process is as follows: First, the operator rotates and fixes the threaded rod 103 on one side of the first platform fixing insulation plate of the platform fixing assembly 1 to the threaded slot 104 on the second platform fixing insulation plate 102. Then, the operator rotates and fixes the threaded protrusion 202 at the upper end of the platform support rod 201 of the platform support assembly 2 to the support threaded groove 106 and tightens it. Next, the operator attaches the two ends of the collection bag 306 of the foreign object collection extension 302 of the foreign object collection device 3 to the hooks 310 at both ends of the hook 305. The operator then places the foreign object collection insulation part 301 into the U-shaped groove 105 between the first platform fixing insulation plate 101 and the second platform fixing insulation plate 102. The operator can place the entire device at the lower end of the disconnecting switch. The foreign object collection insulating part 301 collects foreign objects that fall from the center of the disconnecting switch. The foreign object storage extension part 302 collects foreign objects that fall from the corners of the disconnecting switch and foreign objects that do not fall into the foreign object collection insulating part 301. When the foreign object collection is about to be full, the foreign object collection insulating part 301 can be removed from the U-shaped groove 105, and the foreign object can be removed by removing the storage bag 306 from the hook 305. It is safe and convenient, and greatly reduces the risk of foreign objects falling and causing a short circuit to the equipment ground during foreign object handling. Thus, reliable recovery of foreign objects is achieved when handling foreign objects in a energized disconnecting switch.
