Description

Technical Field

[0001] This utility model relates to the field of disconnecting switch technology, and in particular to a fully sealed disconnecting switch. Background Technology

[0002] A fully sealed disconnect switch is a special type of disconnect switch, characterized by its sealing performance. The design of a fully sealed disconnect switch completely isolates its internal structure from the external environment. It is typically used in high-voltage power systems to prevent external environmental influences on the switch's internal structure, ensuring stable operation and extending its service life. A key feature of fully sealed disconnect switches is their lack of arc-extinguishing capability; they can only open and close circuits when there is no load current. This entry introduces the functions, characteristics, types, applications, anti-misoperation improvements, maintenance, and common problems of disconnect switches.

[0003] Most fully sealed disconnect switches on the market currently rely on natural cooling during long-term use, depending on the natural flow of air for heat dissipation. This method results in poor heat dissipation, which affects the service life of the fully sealed disconnect switches. In addition, existing fully sealed disconnect switches have poor sealing performance, which affects their sealing effect. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] In view of the fact that most fully sealed disconnect switches on the market currently exist, when used for a long time, they usually adopt natural cooling, relying on the natural flow of air for heat dissipation. This method results in poor heat dissipation, which affects the service life of the fully sealed disconnect switch. At the same time, the existing fully sealed disconnect switches have poor sealing effect, which affects the sealing effect of the fully sealed disconnect switch. Therefore, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a fully sealed disconnect switch.

[0007] To solve the above technical problems, this utility model provides the following technical solution: a fully sealed disconnect switch, including a disconnect switch body, a disconnect switch cover plate installed on one side wall of the disconnect switch body, and a sealing component installed on one side wall of the disconnect switch cover plate, an exhaust pipe installed on one end side wall of the disconnect switch body, a heat dissipation component installed on the end of the disconnect switch body away from the exhaust pipe, and a filter frame installed on one end of the heat dissipation component, and bolt mounting rods installed inside the disconnect switch cover plate.

[0008] As a preferred embodiment of the fully sealed disconnect switch of this utility model, wherein: a mounting post is installed on one side wall inside the disconnect switch body, and the mounting post is threadedly connected to the bolt mounting rod.

[0009] By adopting the above technical solution, this solution achieves better installation and fixing effect between the disconnector cover plate and the disconnector body through the threaded connection of the mounting column and the bolt mounting rod.

[0010] As a preferred embodiment of the fully sealed disconnecting switch of this utility model, the heat dissipation component includes a heat dissipation sleeve, which is fixedly installed on the side wall of one end of the disconnecting switch body. A positioning and engaging component is installed on the outer wall of the heat dissipation sleeve, and a heat dissipation fan is installed inside the heat dissipation sleeve. A limit component is installed on the outer wall of the positioning and engaging component.

[0011] By adopting the above technical solution, this solution enables the cooling fan to start, allowing external air to enter the interior of the disconnect switch body through the cooling sleeve.

[0012] As a preferred embodiment of the fully sealed disconnect switch of this utility model, the positioning and engaging assembly includes a fixing sleeve, which is fixedly installed on the outer wall of the heat dissipation sleeve. The top end of the fixing sleeve is provided with a first through hole, and a U-shaped rod is provided inside the first through hole. The side wall of the U-shaped rod is provided with a first threaded hole.

[0013] By adopting the above technical solution and through the design of the first through hole, the U-shaped rod can slide inside the first through hole.

[0014] As a preferred embodiment of the fully sealed disconnecting switch of this utility model, the bottom end of the fixed sleeve is equipped with a second high-pressure spring body, and the top end of the second high-pressure spring body is fixedly connected to the bottom end of the U-shaped rod. The bottom end of the fixed sleeve is equipped with a vertical rod, and the outer wall of the vertical rod is fitted with a sliding sleeve. The outer wall of the sliding sleeve is fixedly connected to the outer wall of the U-shaped rod.

[0015] By adopting the above technical solution, the U-shaped rod can drive the sliding sleeve to slide on the outer wall of the vertical rod through the cooperation of the vertical rod and the sliding sleeve.

[0016] As a preferred embodiment of the fully sealed disconnecting switch of this utility model, the limiting component includes a second threaded hole, which is opened on the side wall of the fixed sleeve. A threaded rod is threadedly connected to the inside of the second threaded hole, and a disc body is installed at one end of the threaded rod.

[0017] By adopting the above technical solution, the threaded connection between the second threaded hole and the threaded rod allows the threaded rod to rotate and slide inside the second threaded hole.

[0018] As a preferred embodiment of the fully sealed disconnect switch of this utility model, the filter frame includes a mounting ring, which is sleeved on the outer wall of the heat dissipation sleeve. A sealing mesh is installed inside the mounting ring, and positioning holes are provided at both the top and bottom ends of the mounting ring.

[0019] By adopting the above technical solution and through the design of the sealing mesh, the dust and lint in the air are filtered out when the disconnecting switch body is dissipating heat.

[0020] As a preferred embodiment of the fully sealed disconnecting switch of this utility model, the sealing assembly includes a first sealing gasket, a sealing layer is installed at the bottom of the first sealing gasket, and a second sealing gasket is installed at the bottom of the sealing layer. The sealing layer includes elastic plates, which are arranged horizontally inside the sealing layer. A first high-pressure spring body is installed on the inner wall of each elastic plate, and the bottom end of the first high-pressure spring body is fixedly connected to the bottom end inside the sealing layer.

[0021] By adopting the above technical solution and through the design of the elastic plate and the first high-pressure spring body, the sealing effect of the sealing assembly is improved by the elastic recovery of the elastic plate and the first high-pressure spring body.

[0022] The advantages of this fully sealed disconnect switch are as follows: First, by activating the cooling fan, external air is drawn into the disconnect switch body through the cooling sleeve, carrying away the heat and expelling it through the exhaust pipe, thus quickly dissipating heat from the disconnect switch body. Simultaneously, the cooling sleeve and mounting ring work together, allowing the vertical rod and sliding sleeve to engage. This enables the U-shaped rod to move up and down on the outer wall of the vertical rod via the sliding sleeve, compressing the second high-pressure spring body and causing deformation. This allows the U-shaped rod to engage with the positioning hole. Furthermore, the threaded rod is threaded to the second and first threaded holes respectively, allowing for engagement with these holes by rotating the threaded rod. This facilitates the installation and removal of the heat dissipation components and filter frame by the operator, and also facilitates the cleaning of the sealing mesh.

[0023] The advantages of this fully sealed disconnect switch are as follows: Firstly, the design of the first sealing gasket, with elastic plates arranged laterally inside the sealing layer, and the design of the first high-pressure spring body, causes the first sealing gasket and the first high-pressure spring body to deform under compression. This allows the disconnect switch cover plate to achieve a better sealing effect when installed with the disconnect switch body through the sealing assembly, thanks to the elastic recovery of the first sealing gasket and the first high-pressure spring body.

[0036] Example 1: Refer to Figures 1-6This is the first embodiment of the present invention. This embodiment provides a fully sealed disconnecting switch, which can achieve the problem that most fully sealed disconnecting switches on the market currently use natural cooling during long-term use, relying on natural airflow for heat dissipation. This method results in poor heat dissipation, thus affecting the service life of the fully sealed disconnecting switch. The present invention includes a disconnecting switch body 1, a disconnecting switch cover plate 2 installed on one side wall of the disconnecting switch body 1, an exhaust pipe 4 installed on one end side wall of the disconnecting switch body 1, a heat dissipation component 5 installed on the end of the disconnecting switch body 1 away from the exhaust pipe 4, and a filter frame 6 installed on one end of the heat dissipation component 5. Bolt mounting rods 7 are installed inside the disconnecting switch cover plate 2. Mounting posts 101 are installed on one side wall inside the disconnecting switch body 1, and the mounting posts 101 are threadedly connected to the bolt mounting rods 7.

[0037] Combination Figure 3 , Figure 4 and Figure 5 In the first embodiment of this utility model, the heat dissipation component 5 includes a heat dissipation sleeve 501, which is fixedly installed on the side wall of one end of the disconnector switch body 1. A positioning and engaging component 502 is installed on the outer wall of the heat dissipation sleeve 501, and a heat dissipation fan 503 is installed inside the heat dissipation sleeve 501. A limiting component 504 is installed on the outer wall of the positioning and engaging component 502. The limiting component 504 includes a second threaded hole 5041, which is opened on the side wall of the fixed sleeve 5021. A threaded rod 5042 is threadedly connected inside the second threaded hole 5041, and a disc body 5043 is installed at one end of the threaded rod 5042. The threaded connection between the threaded rod 5042 and the second threaded hole 5041 allows the threaded rod 5042 to rotate and slide inside the second threaded hole 5041.

[0038] Combination Figure 3 , Figure 4 and Figure 5In the first embodiment of this utility model, the positioning and engaging assembly 502 includes a fixing sleeve 5021, which is fixedly installed on the outer wall of the heat dissipation sleeve 501. A first through hole 5022 is formed at the top of the fixing sleeve 5021, and a U-shaped rod 5023 is disposed inside the first through hole 5022. A first threaded hole 5024 is formed on the side wall of the U-shaped rod 5023. A second high-pressure spring body 5025 is installed at the bottom inside the fixing sleeve 5021. The top end of the high-pressure spring body 5025 is fixedly connected to the bottom end of the U-shaped rod 5023. The bottom end of the fixed sleeve 5021 is equipped with a vertical rod 5026, and a sliding sleeve 5027 is sleeved on the outer wall of the vertical rod 5026. The outer wall of the sliding sleeve 5027 is fixedly connected to the outer wall of the U-shaped rod 5023. Through the cooperation of the vertical rod 5026 and the sliding sleeve 5027, the U-shaped rod 5023 can drive the sliding sleeve 5027 to slide on the outer wall of the vertical rod 5026.

[0039] Combination Figure 2 , Figure 3 and Figure 4 In the first embodiment of this utility model, the filter frame 6 includes a mounting ring 601, which is sleeved on the outer wall of the heat dissipation sleeve 501. A sealing mesh 602 is installed inside the mounting ring 601. Positioning holes 603 are provided at the top and bottom of the mounting ring 601. Through the design of the sealing mesh 602, dust and lint in the air are filtered when the isolating switch body 1 is dissipating heat.

[0040] The specific working principle is as follows: when rapid heat dissipation of the disconnector switch body 1 is required, the cooling fan 503 is first activated to draw external air through the cooling sleeve 501 into the interior of the disconnector switch body 1, carrying away the hot air and expelling it through the exhaust pipe 4, thereby rapidly dissipating heat from the disconnector switch body 1. Simultaneously, the cooling sleeve 501 cooperates with the mounting ring 601, allowing the vertical rod 5026 and the sliding sleeve 5027 to work together, enabling the U-shaped rod 5023 to pass through the sliding sleeve 5027 on the vertical rod 5026. The outer wall of 26 rises and falls, squeezing the second high-pressure spring body 5025 to deform, thereby causing the U-shaped rod 5023 to engage with the positioning hole 603. At the same time, the threaded rod 5042 is threadedly connected to the second threaded hole 5041 and the first threaded hole 5024 respectively. By rotating the threaded rod 5042, it can be threadedly engaged with the second threaded hole 5041 and the first threaded hole 5024, which makes it convenient for operators to install and disassemble the heat dissipation component 5 and the filter frame 6, and also facilitates the cleaning of the sealing mesh 602.

[0041] Example 2: Refer to Figures 1-6This is the first embodiment of the present invention. This embodiment provides a fully sealed disconnect switch, which solves the problem that existing fully sealed disconnect switches have poor sealing performance, thus affecting the sealing effect of the fully sealed disconnect switch. A sealing component 3 is installed on one side wall of the disconnect switch cover plate 2. The sealing component 3 includes a first sealing gasket 301, a sealing layer 302 is installed at the bottom of the first sealing gasket 301, and a second sealing gasket 303 is installed at the bottom of the sealing layer 302. The sealing layer 302 includes an elastic plate 3021, which is arranged horizontally inside the sealing layer 302. A first high-pressure spring body 3022 is installed on the inner wall of each elastic plate 3021, and the bottom of the first high-pressure spring body 3022 is fixedly connected to the bottom of the sealing layer 302. Through the design of the elastic plate 3021 and the first high-pressure spring body 3022, the sealing effect of the sealing component 3 is improved by the elastic recovery of the elastic plate 3021 and the first high-pressure spring body 3022.

[0042] The specific working principle is as follows: First, through the design of the first sealing gasket 301, and through the elastic plate 3021 arranged horizontally inside the sealing layer 302, and through the design of the first high-pressure spring body 3022, the first sealing gasket 301 and the first high-pressure spring body 3022 are compressed and deformed, so that the first sealing gasket 301 and the first high-pressure spring body 3022 elastically recover, so that the sealing effect of the disconnecting switch cover plate 2 is better when it is installed with the disconnecting switch body 1 through the sealing component 3.
