Description

Technical Field

[0001] The invention relates to a relay verification platform, in particular to a relay verification platform with high flexibility. Background Art

[0002] There are a large number of relays in the power system of a pumped storage power station, which requires operators to regularly calibrate relays of different specifications during the operation of the power system to prevent the relays from malfunctioning or refusing to operate due to increased contact resistance or failure, and to ensure the stable operation of the power system. On this basis, the existing relay calibration device, as shown in patents 201710627590.4, 202122263943.1 and 202220471738.6, is mainly composed of a power output terminal, a control terminal, a display screen and multiple electrical rails. When it is necessary to calibrate a relay of any specification, the operator inserts the corresponding relay base into the electrical rail, and then electrically connects the relay base and the power output terminal, and then removes the relay to be tested from the equipment and plugs it into the relay base, so that the relay can be energized through the control terminal and the corresponding detection function can be realized.

[0003] However, the defect of the above device is that, in order to facilitate the installation and replacement of the relay base and achieve the purpose of rapid detection of relays of different specifications, the relay base is only mounted on the outside of the electrical rail and is in a free sliding state during installation, which makes the relay base easily displaced by external collision during the detection process, thereby causing entanglement of the connecting wire and affecting its detection stability. Secondly, in order to improve the detection efficiency, the operator will also operate other relay bases during the detection of any relay, thereby increasing the possibility of collision caused by the relay base.

[0004] Therefore, a relay verification platform capable of positioning a relay base in a detection state is needed. Summary of the invention

[0005] The purpose of the present invention is to provide a highly flexible relay inspection platform, which can realize the positioning of the relay base and facilitate operators to quickly replace the relay base after the inspection is completed.

[0006] The technical solution of the present invention is as follows: a highly flexible relay calibration platform comprises a calibration base, on which power terminals, a control terminal, a display screen and a plurality of electrical rails are respectively provided, a plurality of relay bases are slidably connected to the electrical rails, the relay bases and the power terminals are electrically connected, a slide rail is provided on one side of the electrical rail, a slider is slidably connected in the slide rail, a column extending vertically to the top of the slide rail is provided at one end of the slider, a fixing piece is detachably connected to the top of the column, a plug plate is connected to the slider on one side of the column, a positioning strip is detachably connected to one end of the slide rail, a plurality of slots extending to the outside of the slide rail are spaced apart on one side of the positioning strip, the plug plate is used to longitudinally limit the slider after being inserted into the slot, and the fixing piece is used to longitudinally limit the relay base.

[0007] In the aforementioned highly flexible relay verification platform, the slider is connected with a push-type self-locking buckle, and the plug-in plate is glued to the side wall of the push-type self-locking buckle.

[0008] In the aforementioned highly flexible relay verification platform, the push-type self-locking buckle includes a male buckle and a female buckle that are buckled together, the female buckle is fixedly connected to the slider, the lower end of the male buckle is buckled and connected to the female buckle, and the other end of the male buckle extends to the outside of the slide rail and is connected to the plug plate.

[0009] In the aforementioned highly flexible relay verification platform, the fixing member is an L-shaped elastic pressing piece, and the top and side of the column are connected to the elastic pressing piece via screws.

[0010] In the aforementioned highly flexible relay calibration platform, the cross-sectional shape of the slide rail is C-shaped, and both ends of the slide rail are provided with bending portions for limiting the height of the slider, and the positioning bar is screwed to the bending portion away from the side of the electrical guide rail.

[0011] In the aforementioned highly flexible relay verification platform, the slider has a rectangular tube shape, and the female buckle is buckled and connected to the middle of the slider and is glued to the slider.

[0012] Compared with the prior art, the present invention has the following characteristics:

[0013] (1) The present invention uses the structural coordination of the slide rail and the slider to enable the slider to move horizontally on the slide rail based on the position of the relay base. The structural coordination of the plug plate and the positioning strip allows the slider to be limited by inserting the plug plate after the slider moves into position. On this basis, the fixing member provided on the slider allows the relay base to be positioned after the slider is fixed, thereby effectively preventing the relay base from shifting during the detection process and ensuring its detection stability.

[0014] (2) By connecting the plug plate to the slider via a push-type self-locking buckle, the positioning stability of the slider can be ensured on the one hand, and on the other hand, it can also facilitate the installation and removal of the plug plate by the operator, that is, when removing the plug plate, the operator only needs to pull the male buckle from the slider to release the limit of the slider, thereby realizing the rapid sliding of the slider;

[0015] (3) By using an elastic pressing piece as a fixing part and locking the relay base to limit the position, it is possible to ensure the positioning effect of the relay base while facilitating the operation of the operator; that is, when positioning, the operator only needs to move the relay base into place and then lock the elastic pressing piece into the groove of the relay base. When releasing the positioning, the operator only needs to lift the elastic pressing piece and move the relay base away, thereby effectively improving the operating efficiency;

[0016] Therefore, the present invention can realize the positioning of the relay base and facilitate the operator to quickly replace the relay base after the detection is completed. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0022] Embodiment. A highly flexible relay calibration platform, comprising: Figure 1As shown, it includes a verification machine base 1, on which a power terminal 2, a control terminal 3, a display screen 4 and a plurality of electrical rails 5 are respectively provided. A plurality of relay bases 6 are slidably connected to the electrical rails 5, and the relay bases 6 and the power terminal 2 are electrically connected. A slide rail 7 is provided on one side of the electrical rail 5, and a slider 8 is slidably connected in the slide rail 7. One end of the slider 8 is provided with a column 9 vertically extending to the top of the slide rail 7, and a fixing part 10 is detachably connected to the top of the column 9. A plug plate 11 is connected to the slider 8 on one side of the column 9, and one end of the slide rail 7 is detachably connected to a positioning strip 12, and a plurality of slots 13 extending to the outside of the slide rail 7 are spaced apart on one side of the positioning strip 12. The plug plate 11 is used to longitudinally limit the slider 8 after being inserted into the slot 13, and the fixing part 10 is used to longitudinally limit the relay base 6.

[0023] The slider 8 is connected with a push-type self-locking buckle, and the plug plate 11 is glued to the side wall of the push-type self-locking buckle.

[0024] The push-type self-locking buckle includes a male buckle 14 and a female buckle 15 that are buckled together. The female buckle 15 is fixedly connected to the slider 8. The lower end of the male buckle 14 is buckled and connected to the female buckle 15. The other end of the male buckle 14 extends to the outside of the slide rail 7 and is connected to the plug plate 11.

[0025] The fixing member 10 is an L-shaped elastic pressing piece, the outside of which is wrapped with insulating tape, and the top and side of the column 9 are connected to the elastic pressing piece via screws.

[0026] The cross-sectional shape of the slide rail 7 is C-shaped, and both ends of the slide rail 7 are provided with bending parts for limiting the height of the slider 8 , and the positioning strip 12 is screwed to the bending part on the side away from the electrical guide rail 5 .

[0027] The slider 8 has a rectangular tube shape. The female buckle 15 is buckled and connected to the middle of the slider 8 and is glued to the slider 8. The slider 8 is provided with an opening for the male buckle 14 to be inserted.

[0028] Working principle of the present invention: When the present invention is in use, the operator first inserts the corresponding relay base 6 into the electrical rail 5 according to the specifications of the relay to be tested, and then connects the relay base 6 to the power terminal 2 through the power cord, so that it can be tested through the verification platform after the relay is plugged in.

[0029] After the relay base 6 is wired, the operator slides the slider 8 to one side of the relay base 6 according to the position of the relay base 6, and then places the fixing member 10 in the groove of the relay base 6, so that the fixing member 10 is snapped into the groove under the action of elasticity and is close to the relay base 6, thereby realizing the positioning function. After the fixing member 10 is placed, the operator then inserts the male buckle 14 into the female buckle 15, and inserts the plug plate 11 on one side of the male buckle 14 into the corresponding slot 13, so as to limit the slider 8 with the positioning strip 12 to prevent the relay base 6 and the slider 8 from moving laterally when subjected to external collision.

[0030] When the relay base 6 needs to be replaced, the operator can lift the fixing part 10 to release the limitation on the relay base 6; when the longitudinal position of the slider 8 needs to be adjusted, the operator only needs to pull out the male buckle 14 from the female buckle 15 to release the limitation on the slider 8, and reinsert the male buckle 14 for positioning after the slider 8 moves into place, thereby facilitating the operator's operation.
