Description

Technical Field

[0001] The invention relates to an auxiliary device for transporting GIS equipment, and in particular to a packaging and transportation tool for GIS casings. Background Art

[0002] Gas-insulated metal-enclosed switchgear (GIS), a vital piece of equipment in power systems, is widely used both domestically and internationally. The GIS bushing, a crucial component, has an open end, within which a rod-shaped conductor protrudes. To prevent damage to the conductor protruding from the GIS bushing during transportation and to prevent dust, moisture, and other debris from entering the bushing, which could affect GIS performance, a GIS bushing packaging and transportation tool is typically installed.

[0003] The existing packaging and transportation tooling mainly includes a protective sleeve and a mounting plate. The mounting plate is annular and is connected to the open end of the GIS sleeve through fasteners. One end of the protective sleeve is connected to the inner side of the mounting plate, and the other end of the protective sleeve is closed. The part of the conductor extending from the GIS sleeve is housed in the protective sleeve.

[0004] However, when installing and disassembling the packaging and transportation tooling, the conductor is likely to collide or scrape against the inner wall of the protective sleeve. At the same time, during transportation, vibration may easily cause the conductor to collide or scrape against the inner wall of the protective sleeve, thereby damaging the conductor. In addition, after long-term use, the inner wall of the protective sleeve may adhere to a lot of impurities, thereby affecting the conductor. Summary of the Invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a packaging and transportation tool for GIS casings, which can prevent the packaging and transportation tool itself from affecting or damaging the conductor extending out of the GIS casing.

[0006] According to an embodiment of the present invention, a GIS casing packaging and transportation tool is used for a GIS casing having an open end, wherein a conductor extending out of the open end is provided in the GIS casing. The GIS casing packaging and transportation tool comprises:

[0007] an annular mounting plate for connecting the open end via fastening bolts;

[0008] a protective sleeve, one end of which is connected to the inner side of the annular mounting plate, and the other end of which is sealed;

[0009] a soft rubber protective sleeve, located inside the protective sleeve and extending to both ends of the protective sleeve, wherein a first annular flange is formed circumferentially on the outer side of one end of the soft rubber protective sleeve close to the annular mounting plate, and the soft rubber protective sleeve is used for inserting the conductor;

[0010] The clamping portion is detachably provided on the annular mounting plate to cooperate with the annular mounting plate to clamp the first annular flange.

[0011] The GIS casing packaging and transportation tooling according to the embodiment of the present invention has at least the following beneficial effects:

[0012] When using the GIS casing packaging and transport tooling of the present invention, the annular mounting plate is connected to the open end of the GIS casing using multiple fastening bolts, and the portion of the conductor extending from the open end is inserted into the soft rubber protective sleeve. The sealing effect of the annular mounting plate and the protective sleeve reduces the ingress of dust, moisture, and other foreign matter into the GIS casing. Furthermore, the soft rubber protective sleeve prevents damage to the conductor from collision or abrasion with the inner wall of the protective sleeve during installation and removal of the packaging and transport tooling and during transportation of the GIS casing. Finally, after extended use, if the soft rubber protective sleeve becomes contaminated with impurities, the clamping portion can be removed to release the clamping portion from the first annular flange of the soft rubber protective sleeve. The soft rubber protective sleeve can then be removed and cleaned, and then reinstalled. Because the soft rubber protective sleeve can be regularly removed and cleaned, the impact of impurities on the conductor is reduced, resulting in excellent practicality.

[0014] According to some embodiments of the present invention, a sealing cover is detachably provided at one end of the protective sleeve away from the annular mounting plate, and the sealing cover is used to seal the protective sleeve.

[0015] According to some embodiments of the present invention, a second annular flange is formed circumferentially on the outer side of one end of the soft rubber protective sleeve away from the annular mounting plate, and the sealing cover cooperates with the protective sleeve to clamp the second annular flange.

[0016] According to some embodiments of the present invention, the GIS casing packaging and transportation tooling further includes a first sealing ring and a second sealing ring, wherein the first sealing ring is arranged between the open end and the annular mounting plate, and the second sealing ring is arranged between the sealing cover and the protective casing.

[0017] According to some embodiments of the present invention, an annular depression is circumferentially provided on the inner side of one end of the protective sleeve close to the sealing cover, and the second annular flange is located in the annular depression.

[0018] According to some embodiments of the present invention, the annular mounting plate is provided with a plurality of mounting holes along the circumference, and the mounting holes are used for installing the fastening bolts.

[0039] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0040] Reference below Figures 1 to 6 The following describes a packaging and transportation tool for GIS casing according to an embodiment of the present invention.

[0041] like Figures 1 to 5 As shown, a GIS casing packaging and transportation tool according to an embodiment of the present invention is used for a GIS casing 100. The GIS casing 100 has an open end 101. A conductor 102 extending out of the open end 101 is provided in the GIS casing 100. The GIS casing packaging and transportation tool includes:

[0042] an annular mounting plate 200 for connecting to the open end 101 via fastening bolts;

[0043] A protective sleeve 300, one end of which is connected to the inner side of the annular mounting plate 200, and the other end of which is sealed;

[0044] The soft rubber protective sleeve 400 is located inside the protective sleeve 300 and extends to both ends of the protective sleeve 300. A first annular flange 401 is formed circumferentially on the outer side of the end of the soft rubber protective sleeve 400 near the annular mounting plate 200. The soft rubber protective sleeve 400 is used to insert the conductor 102;

[0045] The clamping portion 500 is detachably mounted on the annular mounting plate 200 to cooperate with the annular mounting plate 200 to clamp the first annular flange 401 .

[0046] When using the GIS casing packaging and transportation tooling of the present invention, the annular mounting plate 200 is connected to the open end 101 of the GIS casing 100 by a plurality of fastening bolts, and the portion of the conductor 102 extending out of the open end 101 is inserted into the soft rubber protective cover 400. The sealing effect of the annular mounting plate 200 and the protective sleeve 300 can reduce the entry of external dust, moisture and other debris into the GIS sleeve 100. In addition, by providing the soft rubber protective sleeve 400, it is possible to prevent the conductor 102 from colliding or scraping with the inner wall of the protective sleeve 300 during the installation, disassembly of the packaging and transportation tooling and transportation, thereby preventing the conductor 102 from being damaged. Finally, after long-term use, when the soft rubber protective sleeve 400 is adhered with a large amount of impurities, the clamping part 500 can be removed, and the clamping part 500 releases the clamping of the first annular flange 401 of the soft rubber protective sleeve 400. The soft rubber protective sleeve 400 can then be pulled out and cleaned, and then the cleaned soft rubber protective sleeve 400 can be reinstalled. Since the soft rubber protective sleeve 400 can be regularly disassembled and cleaned, the impurities on the soft rubber protective sleeve 400 can be reduced from affecting the conductor 102, thereby improving practicality.

[0047] It should be noted that, in general, the open end 101 of the GIS casing 100 can be provided with a flange, and the annular mounting plate 200 can be connected to the flange via multiple fastening bolts. The protective sleeve 300 can be welded or integrally formed with the inner side of the annular mounting plate 200 to enhance sealing. The protective sleeve 300 can be made of a hard material such as steel, iron, or aluminum to enhance protection for the conductor 102. The soft rubber protective cover 400 can be made of soft rubber or other suitable soft colloid. The soft rubber protective cover 400 is a soft and elastic material that prevents damage to the conductor 102. The clamping portion 500 is detachably disposed on the side of the annular mounting plate 200 facing away from the protective sleeve 300. The clamping portion 500 and the end surface of the annular mounting plate 200 facing away from the protective sleeve 300 form a clamping area. The first annular flange 401 is located within the clamping area, thereby clamping the first annular flange 401 and thus enabling installation of the soft rubber protective cover 400.

[0048] In some embodiments of the present invention, Figure 5 As shown, a mounting ring 201 is provided on the side of the annular mounting plate 200 facing away from the protective sleeve 300. The mounting ring 201 is coaxially arranged with the protective sleeve 300. The clamping portion 500 is provided in an annular structure, and the outer wall of the clamping portion 500 is threadedly connected to the inner wall of the mounting ring 201. Specifically, the inner wall of the mounting ring 201 is provided with an internal thread, and the outer wall of the clamping portion 500 is provided with an external thread. The mounting ring 201 is threadedly connected to the mounting ring 201 through the mating of the internal and external threads. By rotating the clamping portion 500, the clamping portion 500 can be moved closer to or away from the annular mounting plate 200, thereby clamping or loosening the first annular flange 401. This is convenient to operate and saves time and effort.

[0049] It should be noted that the clamping portion 500 is configured as an annular structure to facilitate the passage of the conductor 102. Of course, the inner diameter of the clamping portion 500 needs to be larger than the outer diameter of the conductor 102. In addition, the clamping portion 500 can also be detachably connected in other ways, such as connecting to the annular mounting plate 200 via fasteners.

[0050] In some embodiments of the present invention, Figure 6 As shown, the end of the protective sleeve 300 away from the annular mounting plate 200 is detachably provided with a cover 301, which is used to seal the protective sleeve 300. The cover 301 can seal the end of the protective sleeve 300 away from the annular mounting plate 200 to prevent the ingress of impurities such as moisture and dust. In addition, the cover 301 is removable, thereby facilitating the observation of the conductor 102 and the removal and installation of the soft rubber protective sleeve 400.

[0051] It should be noted that the cover 301 can be connected to the end of the protective sleeve 300 away from the annular mounting plate 200 by bolts, clamping or threads, which will not be described in detail here.

[0052] In some embodiments of the present invention, Figure 6 As shown, a second annular flange 402 is formed circumferentially on the outer side of the end of the soft rubber protective sleeve 400 away from the annular mounting plate 200. The cover 301 cooperates with the protective sleeve 300 to clamp the second annular flange 402. This arrangement clamps both ends of the soft rubber protective sleeve 400, preventing the soft rubber protective sleeve 400 from expanding or contracting. The soft rubber protective sleeve 400 is kept in a tensioned state, thereby providing better protection for the conductor 102.

[0053] In some embodiments of the present invention, the GIS casing packaging and transportation tooling further includes a first sealing ring and a second sealing ring. The first sealing ring is disposed between the open end 101 and the annular mounting plate 200, and the second sealing ring is disposed between the sealing cover 301 and the protective casing 300. The provision of the first and second sealing rings provides a better sealing effect and can further reduce the ingress of impurities such as moisture and dust into the GIS casing 100 and the protective casing 300.

[0054] In some embodiments of the present invention, Figure 6 As shown, an annular recess 302 is circumferentially provided on the inner side of the end of the protective sleeve 300 near the cover 301, and the second annular flange 402 is located within the annular recess 302. In other words, the second annular flange 402 is not clamped between the end surface of the protective sleeve 300 near the cover 301 and the end surface of the cover 301, but is located within the annular recess 302. This prevents interference between the second annular flange 402 and the second sealing ring, thereby reducing the second sealing ring's impact on the clamping effect of the second annular flange 402 or the second annular flange 402's impact on the sealing effect of the second sealing ring.

[0055] In some embodiments of the present invention, Figure 1 As shown, the annular mounting plate 200 is provided with multiple mounting holes 202 along its circumference for installing fastening bolts. Correspondingly, the flange of the GIS casing 100 is provided with multiple positioning holes along its circumference. To install the annular mounting plate 200, align the mounting holes 202 on the annular mounting plate 200 with the positioning holes on the flange of the GIS casing 100. Then, install the fastening bolts, resulting in a tighter connection and a better seal.

[0056] In some embodiments of the present invention, Figure 1 and Figure 4 As shown, an annular positioning plate 203 is provided circumferentially on the outer side of the annular mounting plate 200. The annular positioning plate 203 is adapted to fit over the open end 101. When installing the GIS casing packaging and transport tool of this embodiment, the annular positioning plate 203 is placed over the open end 101 of the GIS casing 100. The inner sidewall of the annular positioning plate 203 fits against the outer sidewall of the open end 101 of the GIS casing 100, thereby aligning the circle containing all the mounting holes 202 with the circle containing all the positioning holes. Subsequently, the protective casing 300 is rotated. When one mounting hole 202 aligns with one of the positioning holes, the remaining mounting holes 202 also align with the corresponding positioning holes. In other words, the provision of the annular positioning plate 203 in this embodiment allows for quick alignment of the mounting holes 202 with the positioning holes, facilitating the installation of fastening bolts. This makes installation of the GIS casing packaging and transport tool of this embodiment more convenient and rapid.

[0057] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the annular mounting plate 200 is provided with a through-hole for connecting to the GIS casing 100. A self-sealing valve 204 is provided on the side of the annular mounting plate 200 near the protective casing 300, connecting to the through-hole. This self-sealing valve 204 allows the interior of the GIS casing 100 to be evacuated and then filled with a slightly positive pressure of clean gas, such as high-purity nitrogen, to reduce humidity within the GIS casing 100 and prevent the risk of condensation. It should be noted that the self-sealing valve 204, also known as a self-closing valve, is a common structure used for inflation and deflation, and its specific structure and operating principle are not detailed here.

[0058] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, multiple reinforcing ribs 303 are provided between the outer wall of the protective sleeve 300 and the annular mounting plate 200. The reinforcing ribs 303 are arranged along the circumference of the protective sleeve 300. The provision of the reinforcing ribs 303 enhances the structural strength of the GIS sleeve packaging and transportation tooling of this embodiment, making it less susceptible to damage and extending its service life.

[0059] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the scope of the present invention.
