[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0028] like Figure 1 and Figure 2As shown, a primary and secondary integrated pole-mounted vacuum circuit breaker includes: a base frame 20, the base frame 20 is a rectangular plate with an inverted L-shaped cross-section, a circuit breaker body 21 is provided on the top of the base frame 20, and a threaded groove is provided on the front wall of the base frame 20. The model of the circuit breaker body 21 is consistent with the model of the circuit breaker body used in the prior art (publication number: CN112233932A). This is the existing technology and will not be described in detail here.

[0029] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, the corrosion-resistant structure is arranged on the wall surface of the base 20 for connecting with the circuit breaker body 21. The corrosion-resistant structure includes: an alignment plate 30, a card slide 32 and a stud 35. The alignment plate 30 is symmetrically fixedly connected to the inner bottom surface of the base 20, the card slide 32 is symmetrically fixedly connected to the bottom of the circuit breaker body 21, and the stud 35 is threadedly connected to the bottom of the screw plate 33. The symmetrical alignment plate 30 can be clamped with the symmetrical card slide 32.

[0030] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, the alignment plate 30 is a plate with a broken line cross section, and the card slide plate 32 is also a plate with a broken line cross section. The inner wall surface of the card slide plate 32 can fit the outer wall surface of the alignment plate 30, and the bottom of the alignment plate 30 is symmetrically provided with threaded holes for fitting studs 35. The corrosion-resistant structure also includes a front baffle 31, a screw plate 33 and a rainproof box 34. The front baffle 31 is fixedly connected to the top of the front wall surface of each alignment plate 30. The front baffle 31 can fill the gap between the front wall surface of the alignment plate 30 and the wall surface of the base frame 20. The front baffle 31 is a plate with an inverted right-angled trapezoid. The rainproof box 34 is fixedly connected to the bottom of each card slide plate 32, and the screw plate 33 is fixedly connected to the bottom of each card slide plate 32. 3 is fixedly connected to the side wall of each card slide 32. The top of each screw plate 33 is symmetrically penetrated by a threaded hole for adapting to the stud 35. The rainproof box 34 is composed of a hollow isosceles triangular box in the upper half and a plate with a U-shaped cross-section in the lower half. The top inclined surface of the rainproof box 34 can fit the bottom inclined surface of the card slide 32. The screw plate 33 is a rectangular plate. The threaded holes in the wall of the screw plate 33 can coincide with the threaded holes in the wall of the positioning plate 30. A stud 35 is respectively set in each threaded hole in the wall of the screw plate 33. The stud 35 can simultaneously penetrate the threaded holes in the wall of the screw plate 33 and the positioning plate 30.

[0031] When in use, the base frame 20 is first installed on the electric pole smoothly through the threaded grooves on its wall surface. Then, when installing the circuit breaker body 21, the symmetrical card plate 32 wall surface is first aligned with the bottom inclined surface of the positioning plate 30 and slidably engaged. Then, when the card plate 32 and the positioning plate 30 are slid and engaged, the inner inclined surface of the card plate 32 is completely aligned with the outer inclined surface of the positioning plate 30. Then, the screw plate 33 stops sliding when it slides along with the card plate 32 until it coincides with the threaded hole on the wall surface of the positioning plate 30. At this time, the stud 35 is screwed into the threaded holes on the screw plate 33 and the wall surface of the positioning plate 30 from bottom to top. The stud 35 is screwed until the end thereof protrudes from the wall surface of the positioning plate 30 and the screwing can be stopped.

[0032] In summary, by providing an anti-corrosion structure, the circuit breaker body 21 can be quickly installed on the top of the base frame 20, and the studs 35 after installation will not be corroded by rainwater. The anti-corrosion structure locks the position of the studs 35 by sliding the card plate 32 and the alignment plate 30. When rainwater comes, the card plate 32 and the rainproof box 34 can completely surround and block the studs 35, thereby effectively preventing the problem of rainwater eroding the studs 35. In addition, this solution only needs to screw four studs 35 to complete the installation. Therefore, compared with the existing technology, this solution can not only prevent rainwater from corroding the studs 35 but also quickly and conveniently install the circuit breaker body 21.

[0033] like Figure 1 and Figure 5 As shown, the wall surface of the alignment plate 30 is provided with a snap-fit ​​structure, which includes a clamping tube 40 and an alignment groove 41. The clamping tube 40 is clamped on one side of the alignment plate 30. The clamping tube 40 is a tube with a U-shaped cross-section. The side wall opening of the clamping tube 40 is clamped on the side wall surfaces of the alignment plate 30 and the screw plate 33. The top of the clamping tube 40 is symmetrically opened with a U-shaped opening, and the top of each U-shaped opening is respectively provided with an alignment groove 41. The snap-fit ​​structure also includes a nut 42 and an alignment ring 43. The nut 42 is threadedly connected to the end of the stud 35 passing through the alignment plate 30. The alignment ring 43 is fixedly connected to the bottom of each nut 42. The alignment ring 43 is annular, and the alignment groove 41 is also annular. The alignment groove 41 can adapt to the size of the alignment ring 43.

[0034] In actual use, after the circuit breaker body 21 is installed to the top of the base frame 20 through the corrosion-resistant structure, a snap-fit ​​structure can be added if the fixing effect of the circuit breaker body 21 needs to be improved. When installing the snap-fit ​​structure, first align the side wall opening of the clamping tube 40 with the screw plate 33 and the side wall of the alignment plate 30 and clamp it in. When clamping the clamping tube 40, align the U-shaped groove on the wall of the alignment groove 41 with each stud 35. Then, after the inner wall surface of the clamping tube 40 cavity and the side wall surface of the alignment plate 30 are in contact, stop moving the clamping tube 40. Then, thread the bottom of the nut 42 and the end of each stud 35 passing through the alignment plate 30. As the nut 42 is rotated, the alignment ring 43 enters each alignment groove 41 to complete the installation.

[0035] In summary, by setting up a snap-fit ​​structure, the connection and fixing effect of the circuit breaker body 21 and the base 20 can be improved by adding it, which can effectively improve the fitting effect of the alignment plate 30 and the card plate 32, and can effectively improve the combined fixing life of the circuit breaker body 21 and the base 20.

[0036] Working principle: First, the base frame 20 is smoothly installed on the utility pole through the threaded groove opened on its wall. Then, when installing the circuit breaker body 21, the symmetrical card slide 32 wall is first aligned with the bottom inclined surface of the alignment plate 30 for sliding engagement. Then, when the card slide 32 and the alignment plate 30 are slid and aligned, the inner inclined surface of the card slide 32 will be completely aligned with the outer inclined surface of the alignment plate 30. Then, the screw plate 33 stops sliding when it slides with the card slide 32 and coincides with the threaded hole on the wall of the alignment plate 30. At this time, the stud 35 is screwed from bottom to top into the threaded holes on the screw plate 33 and the wall of the alignment plate 30. The stud 35 is screwed until the end protrudes from the wall of the alignment plate 30 and then stopped. The installation is now complete.
