[0060] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below by taking examples. The terms and pronouns about persons in the present patent application are not limited to specific genders.

[0061] The present application provides a kind of for vacuum arc-extinguishing chamber's bearing device, it is not only convenient in the cleaning process of the component of vacuum arc-extinguishing chamber, and it is convenient to clean these components.The component here is for example copper component.More specifically, the component is for example copper bar 51 or tube core.

[0062] The bearing device for vacuum arc-extinguishing chamber includes bearing basket 1, and the bearing basket 1 includes bottom disc and fence.

[0063] As Figures 1 to 4As shown, the chassis is used to carry multiple components 5 of the vacuum interrupter, the chassis comprises several metal support bars 11, and there is a hollow part 111 between two adjacent metal support bars 11. The multiple components 5 of the vacuum interrupter can be placed on the chassis, and the multiple components 5 can be the same kind of component, which is convenient for management and placement, and of course different kinds of components can also be placed according to actual needs. The hollow part 111 between the metal support bars 11 means that when immersion cleaning or flushing cleaning is used, the components 5 do not need to be taken out of the carrying basket 1, and due to the existence of the hollow part 111, not only can the water not stay in the carrying basket 1, but also can flow out through the hollow part 111, and the components 5 in the carrying basket 1 can be cleaned from multiple angles.

[0064] The fence surrounds the periphery of the chassis and is fixed to the chassis, and the fence is used to block the components 5 of the vacuum interrupter from falling out of the carrying basket 1. The height of the fence is higher than that of the chassis, so as to avoid damage caused by the components 5 falling out of the carrying basket 1 during transportation.

[0065] As an example, as shown in Figure 1 and Figure 2 , the fence can comprise several metal bars 61, for example, the fence comprises a rectangular frame composed of metal bars 61, and is fixed to the chassis by several vertical metal bars 61, which are perpendicular to the chassis. An L-shaped metal piece 7 is also arranged at each corner of the fence, which abuts against the metal bar 61, and the metal bar 61 is located inside the L-shaped metal piece 7, so that when another carrying basket 1 is placed above the carrying basket 1, the L-shaped metal pieces 7 can also play a role in fixing the position.

[0066] As another example, as shown in Figure 3 , the fence can comprise several metal rods 62, which are perpendicular to the chassis. Such a structure saves cost. Of course, the fence of Figure 3 can also be arranged as the same fence as Figure 1 and Figure 2 .

[0067] As an example, the carrying basket 1 also comprises a support rod 3 fixed between the opposite two sides of the fence. The support rod 3 not only can enhance the strength of the carrying basket 1, but also can be used as a handle for convenient transportation.

[0068] According to the carrying device for the vacuum interrupter of the utility model, by arranging several metal support bars 11 on the chassis and having a hollow part 111 between the adjacent metal support bars 11, the carrying device not only facilitates the transportation of multiple components 5, but also facilitates cleaning.

[0069] There are many ways to implement this chassis, such as Figures 1 to 3 As shown, it illustrates three implementation methods. The implementation methods for each chassis will be described below.

[0070] Implementation Method 1:

[0071] like Figure 1 As shown, the chassis includes a first frame 12, several metal support strips 11, and several first insulating sleeves 13.

[0072] The first border 12 can be rectangular, for example, a rectangular border made of metal strip 61.

[0073] The several metal support bars 11 are arranged parallel to each other, with both ends of each metal support bar 11 fixed to the first frame 12. Two adjacent metal support bars 11 are used to support one component 5, and the radial cross-section of each metal support bar 11 is circular. Figure 1 As can be seen, component 5 can be placed between two metal support bars 11, that is, at the hollow part 111, and the two metal support bars 11 support component 5. Multiple components 5 can be placed in the carrying basket 1, so that one carrying basket 1 can transport multiple components 5 at the same time, which is highly efficient.

[0074] Each metal support bar 11 is fitted with a first insulating sleeve 13, which can be made of plastic or rubber. The use of this first insulating sleeve 13 prevents direct contact between the component 5 and the metal support bar 11, thus avoiding bumps or scratches. As an example, the first insulating sleeve 13 is rotatably fitted onto the metal support bar 11. When the component 5 is a copper rod 51 or other cylindrical part, after the component 5 is placed on the metal support bar 11, the operator can easily adjust its position by rotation.

[0075] This structure is relatively simple and has a low cost.

[0076] Implementation Method Two:

[0077] like Figure 2 As shown, the chassis includes a first frame 12, several parallel metal support bars 11, and several first insulating sleeves 13, as well as several parallel reinforcing ribs 14. Each reinforcing rib 14 has its two ends fixed to the first frame 12, and its extension direction is perpendicular to the extension direction of the metal support bars 11. The reinforcing rib 14 is fixed to the metal support bars 11. That is, the reinforcing rib 14 and the metal support bars 11 are fixed together at their intersection. As an example, they can be fixed together by welding. The radial cross-section of the reinforcing rib 14 can be rectangular, which facilitates welding to the circular metal support bars 11.

[0078] In the presence of the reinforcing rib 14, several first insulating sleeves 13 are sleeved on the same metal strip, so as to avoid the first insulating sleeves 13 at the position where the metal support strip 11 intersects with the reinforcing rib 14. As shown in Figure 2 , the number of reinforcing ribs 14 is 2, and there are 3 first insulating sleeves 13 on one metal support strip 11.

[0079] The reinforcing rib 14 can increase the strength of the whole bearing basket 1 and can bear larger weight of the parts 5.

[0080] Implementation three

[0081] As shown in Figure 3 , the bottom disc includes a second frame 21, several metal support strips 11 and several metal wave strips 22.

[0082] The structure of the second frame 21 can be the same as that of the first frame 12, that is, it can be a rectangular frame, for example, a rectangular frame made of a metal strip 61.

[0083] The several metal support strips 11 are all fixed on the second frame 21, and the several metal support strips 11 are parallel.

[0084] Each metal support strip 11 is fixed with a metal wave strip 22, the metal wave strip 22 has a wave crest and a wave trough, and one part 5 can be placed in the wave troughs in the same column, and the radial section of the metal wave strip 22 is circular. As shown in Figure 3 , it shows the case where several parts 5 are placed on the bottom disc. The Figure 3 fence shown in the figure is connected to the metal wave strip 22.

[0085] Some parts 5 have only a part in a cylindrical shape, and the cylindrical shape is fixedly connected with other parts, and the metal wave strip 22 can lift the position of the part 5 when bearing such a part 5, so as to avoid the other parts. For example Figure 3 , as shown in the figure, the part 5 includes a copper bar 51 and a copper sheet 52 fixed to one end of the copper bar 51, and the diameter of the copper sheet 52 is greater than that of the copper bar 51. At this time, the bearing basket 1 shown in Figure 3 , the copper sheet 52 is placed on the outer part of the metal wave strip 22, so as to better fix the position of the part 5.

[0086] As an example, the bottom disc further includes a second insulating sleeve 23, which is sleeved on the metal wave strip 22. The material of the second insulating sleeve 23 can be plastic or rubber, and the use of the second insulating sleeve 23 can avoid damage caused by direct contact between the metal support strip 11 and the part 5.

[0087] Figure 3 The structure shown in the figure is suitable for irregularly shaped parts 5.

[0088] In addition, the carrying device may also include a carrying basket 4, which can accommodate multiple carrying crates 1, arranged sequentially from top to bottom. Using this carrying basket 4, multiple carrying crates 1 can be moved at once, and components 5 located in the same carrying crate 1 can be cleaned simultaneously, improving the utilization rate of the cleaning equipment. Figure 4 The diagram shows the case where the support basket 1, implemented in method three, is located in the support net basket 4.

[0089] like Figure 4 As shown, the carrying basket 4 includes a base basket 41 and a third frame 42. The third frame 42 surrounds the base basket 41, and its top has a carrying area A for supporting another carrying basket 4. This further improves the utilization rate of the cleaning equipment, allowing for the cleaning of more components 5.

[0090] As an example, the third frame 42 includes several ribs 421 and a rectangular frame 422. One end of the ribs 421 is perpendicular to the bottom mesh basket 41. Each rib 421 includes a first bend 4211 and a second bend 4212. The first bend 4211 extends outward to support the mesh basket 4, and the second bend 4212 extends in a direction perpendicular to the bottom mesh basket 41. Each first bend 4211 forms a support area A, such as... Figure 4 As shown, the load-bearing area A exists in four directions. Each second bend 4212 is fixed to the rectangular frame 422. The rib 421 is integrally formed, and the corresponding first bend 4211 and second bend 4212 can be formed through processing. Such a structure is relatively simple to implement and has a low cost.

[0091] It is conceivable that the aforementioned "basket" and "net" indicate that the component has multiple holes and is not completely sealed. In order to facilitate cleaning, such as by soaking, the carrier device is designed so that the components therein can come into contact with water over a large area, which is beneficial to improving cleaning efficiency.

[0092] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
