"In one embodiment" appearing in different places in the specification does not mean the same embodiment, nor is it an independent or alternative embodiment that excludes other embodiments.
[0023] Embodiment 1
[0024] Reference Figs. 1-3 For the first embodiment of the present application, the embodiment provides a power plant excitation variable cooler base device, specifically comprising, a track mechanism 100, comprising a slide rail assembly 101 fixed in the excitation variable cooler box, a slide block assembly 102 slidingly arranged on the slide rail assembly 101, and a connecting plate assembly 103 fixed on the upper part of the slide block assembly 102; a pulling mechanism 200, comprising a nut 201 fixed on the upper part of the connecting plate assembly 103, and a screw rod 202 threaded into the nut 201; a fixing mechanism 300, comprising a baffle 301 fixed in the excitation variable cooler box and abutting one end of the slide rail assembly 101, and a fixing assembly 302 arranged on the excitation variable cooler box door plate W.
[0025] Further, the slide rail assembly 101 comprises a first slide rail 101a and a second slide rail 101b, and the first slide rail 101a and the second slide rail 101b are arranged in parallel.
[0026] It should be noted that the first slide rail 101a and the second slide rail 101b arranged in parallel can ensure that the sliding direction of the sliding object on the first slide rail 101a and the second slide rail 101b is parallel to the first slide rail 101a and the second slide rail 101b.
[0027] Further, the slider assembly 102 comprises a first slider 102a and a second slider 102b which are slidably arranged on the first slide rail 101a, and a third slider 102c and a fourth slider 102d which are slidably arranged on the second slide rail 101b; the first slider 102a and the third slider 102c are close to one end of the excitation transformer, and the second slider 102b and the fourth slider 102d are away from the other end of the excitation transformer.
[0028] Preferably, the connecting plate assembly 103 comprises a first connecting plate 103a which is fixed on the upper part of the first slider 102a and the third slider 102c, and a second connecting plate 103b which is fixed on the upper part of the second slider 102b and the fourth slider 102d.
[0029] In this embodiment, after the generator excitation transformer cooling fan is installed on the upper part of the first connecting plate 103a and the second connecting plate 103b, the generator excitation transformer cooling fan can slide along the length direction of the first slide rail 101a and the second slide rail 101b stably under the support of the four corners of the first slider 102a, the second slider 102b, the third slider 102c and the fourth slider 102d; after the maintenance personnel pull or push the end of the screw rod 202, the generator excitation transformer cooling fan can slide away from or close to the excitation transformer.
[0030] Embodiment 2
[0031] Reference Figs. 1-3 For the second embodiment of the utility model, this embodiment is based on the previous embodiment.
[0032] Specifically, the nut 201 is fixed on the upper part of the second connecting plate 103b, one end of the screw rod 202 is threadedly connected in the nut 201, and the other end penetrates through the excitation transformer cooler box door plate W and extends to the outside of the excitation transformer cooler box.
[0033] Further, the baffle 301 is fixed on the end of the first slide rail 101a and the second slide rail 101b close to the excitation transformer.
[0034] It should be noted that the baffle 301 can completely block the side wall of the first slider 102a and the third slider 102c.
[0035] Further, the fixing assembly 302 comprises a fixing plate 302a and a fixing bolt 302b which is threadedly connected on the fixing plate 302a and the excitation transformer cooler box door plate W; one end of the screw rod 202 abuts against the side wall of the fixing plate 302a.
[0036] In the embodiment, when the generator excitation transformer cooling fan is fixed, the installer needs to tighten the fixing bolt 302b so that the fixing plate 302a can press the end of the screw rod 202; after the screw rod 202 transmits the pressure to the connecting plate assembly 103, the connecting plate assembly 103 will push the first sliding block 102a and the third sliding block 102c to press on the side wall of the baffle 301, so that the generator excitation transformer cooling fan fixed on the upper part of the connecting plate assembly 103 can be stable during operation; the baffle 301 can completely block the side wall of the first sliding block 102a and the third sliding block 102c, so that the contact area of the first sliding block 102a and the third sliding block 102c with the baffle 301 is maximized, further improving the stability of the generator excitation transformer cooling fan during operation.
[0037] Preferably, the excitation transformer cooler door plate W is threadedly connected to the excitation transformer cooler.
[0038] It should be noted that the excitation transformer cooler door plate W is a standard door plate made of a steel plate with a thickness of 6 mm, which can stably support the fixing bolt 302b, so that the fixing plate 302a can stably press the screw rod 202.
[0039] In the embodiment, when the generator excitation transformer cooling fan is damaged and needs to be repaired by the maintenance personnel, the fixing bolt 302b needs to be unscrewed to remove the fixing plate 302a, and then the screw rod 202 is pulled to make the generator excitation transformer cooling fan slide along the slide rail assembly 101 away from the excitation transformer and close to the excitation transformer cooler door plate W. The generator excitation transformer cooling fan away from the excitation transformer greatly reduces the risk of high voltage and avoids electric shock of the maintenance personnel.
[0040] It should be noted that after the generator excitation transformer cooling fan is slid to close to the excitation transformer cooler door plate W, the maintenance personnel can remove the excitation transformer cooler door plate W from the excitation transformer cooler. The operation of first pulling the generator excitation transformer cooling fan and then removing the excitation transformer cooler door plate W can fully play the isolation role of the excitation transformer cooler door plate W. The excitation transformer cooler door plate W not only serves as a temporary fulcrum when the maintenance personnel pull the generator excitation transformer cooling fan, but also prevents the maintenance personnel from accidentally falling into the excitation transformer cooler, further reducing the risk of high voltage.
[0041] It should be noted that after the maintenance personnel remove the excitation transformer cooler door plate W, the excitation transformer cooler door plate W can be removed along the length direction of the screw rod 202, and the generator excitation transformer cooling fan can be repaired.
[0042] It is to be understood that the development process can involve both substantial design and experimental efforts. As such, in embodiments of the application, design synthesis and / or experimental tests can be conducted to help improve the performance of the devices. Efforts can be directed to concurrently improving one or more performance characteristics of the devices.
[0043] It should be noted that the above examples are only used to illustrate the technical solutions of the present application but not limit the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or equivalently replaced without departing from the spirit and scope of the present application, and all modifications and equivalent replacements should be included in the scope of the claims of the present application.
