Description

Technical Field

[0001] The utility model relates to the technical field of generators, in particular to a rotor AC impedance tester for generator detection. Background Art

[0002] A generator is a mechanical device that converts other forms of energy into electrical energy. It is driven by a turbine, steam turbine, diesel engine or other power machinery, and converts the energy generated by water flow, air flow, fuel combustion or nuclear fission into mechanical energy and transmits it to the generator, which then converts it into electrical energy. Generators are widely used in industrial and agricultural production, national defense, science and technology, and daily life. When using a generator, a rotor AC impedance tester is needed to detect whether the generator is generating electricity normally and whether it can be used normally.

[0003] Among them, the existing patent with announcement number CN219871540U discloses a rotor AC impedance tester for generator detection, including a detector, a protective cover, a connecting block and a positioning block. The protective cover is arranged inside the detector, and the left side of the protective cover is fixedly connected to the connecting block, and the front side of the detector is fixedly connected to the positioning block. The positioning block is used in conjunction with the connecting block, and a positioning cavity is provided inside the positioning block, and an adjustment mechanism and two positioning mechanisms are provided inside the positioning cavity; however, the above patent does not have a cable sorting function, resulting in the cables being staggered when the tester is used. In severe cases, it is easy to cause entanglement, causing the cables to be bent and damaged, and at the same time, affecting the appearance, thereby failing to meet the customer's usage needs.

[0004] Therefore, those skilled in the art have provided a rotor AC impedance tester for generator detection to solve the problems raised in the above background technology. Utility Model Content

[0005] In order to improve the problem of lack of cable arrangement function, the utility model provides a rotor AC impedance tester for generator detection.

[0006] The utility model provides a rotor AC impedance tester for generator detection, which adopts the following technical solutions:

[0007] The rotor AC impedance tester for generator detection includes a tester body, a slide rail is fixedly connected to the bottom of the front side of the tester body, a slide plate is evenly slidably connected to the outer surface of the slide rail, a positioning column is fixedly connected to the top of the slide plate, a movable frame is slidably connected to the outer surface of the positioning column, a stud is fixedly connected to the top of the front side of the positioning column, the front side of the stud passes through the movable frame and is threadedly connected to a limiting nut, a gooseneck is fixedly connected to the top of the movable frame, a concave frame is fixedly connected to the top of the gooseneck, a screw is threadedly connected to the top of the concave frame, the bottom of the screw passes through the concave frame and is rotatably connected to a pressure plate through a bearing, and heat dissipation components are arranged on the left and right sides of the tester body.

[0008] By adopting the above technical solution, when the tester body is in use, the staff takes the slide plate, so that the slide plate drives the positioning column to slide on the outer surface of the slide rail. When the slide plate moves to a suitable position, the staff turns the limit bolts in sequence, so that the limit bolts are inserted into the inner cavity of the corresponding pin hole, thereby limiting the connection between the slide plate and the slide rail.

[0009] Next, the staff rotates the limit nut in sequence according to the cable arrangement height, so that the limit nut rotates away from the movable frame on the outer surface of the stud thread, thereby releasing the limit on the movable frame. Next, the staff moves the movable frame upward in sequence, so that the movable frame drives the gooseneck tube to move upward. When the gooseneck tube drives the concave frame to move upward to the appropriate arrangement height, the staff rotates the limit nut in the opposite direction, so that the limit nut rotates in the opposite direction on the outer surface of the stud thread and fits tightly with the connection of the movable frame, thereby limiting the connection between the movable frame and the positioning column, thereby completing the adjustment of the cable arrangement height;

[0010] Then, the staff passes the cables through the concave frame and the pressure plate in turn. Next, the staff turns the handle so that the handle drives the screw to rotate on the inner surface of the concave frame. At the same time, the screw drives the pressure plate and the anti-slip pad to move downward, so that the pressure plate, concave frame, anti-slip pad and positioning groove are used in coordination to press and limit the cables, thereby achieving cable organization.

[0013] Optionally, pin holes are evenly opened on the front side of the slide rail, and a limiting bolt is threadedly connected to the front side of the slide plate, and one end of the limiting bolt passes through the slide plate and extends to the inner cavity of the pin hole.

[0014] By adopting the above technical solution and arranging the pin hole and the limiting bolt, the connection between the slide rail and the slide plate can be limited.

[0015] Optionally, a movable groove for use with a stud is provided on the front side of the movable frame, and the stud is located in an inner cavity of the movable groove.

[0016] By adopting the above technical solution and setting the movable groove, the movable frame can be easily moved and at the same time, the movable frame can be limited.

[0017] Optionally, the outer surface of the limiting nut is tightly fitted with the connection between the movable frame, and the number of the limiting nuts is four.

[0018] Optionally, an anti-skid pad is fixedly connected to one side of the pressing plate and the concave frame opposite to each other, and a positioning groove is provided on one side of the anti-skid pad.

[0019] By adopting the above technical solution, the provision of the anti-skid pad and the positioning groove can position and protect the cable, and at the same time, increase the friction between the cable and the pressure plate and the concave frame, thereby improving stability.

[0020] Optionally, four corners of the bottom of the tester body are fixedly connected with support legs, and the number of the support legs is four.

[0021] By adopting the above technical solution and the setting of the supporting legs, the tester body can be supported.

[0022] Optionally, the outer surface of the pressing plate is slidably connected to the connection point of the concave frame, and the top of the screw is fixedly connected with a rotating handle.

[0023] By adopting the above technical solution and setting of the rotating handle, the screw can be easily rotated.

[0024] In summary, the utility model has the following beneficial effects:

[0040] In this embodiment, the heat dissipation effect of the tester body 1 can be improved by providing the heat dissipation component 12 .

[0041] The implementation principle of the utility model is as follows: when the tester body 1 is used, the staff takes the slide plate 3 in turn, so that the slide plate 3 drives the positioning column 4 to slide on the outer surface of the slide rail 2. When the slide plate 3 moves to a suitable position, the staff rotates the limit bolt 14 in turn, so that the limit bolt 14 is inserted into the inner cavity of the corresponding pin hole 13, thereby limiting the connection between the slide plate 3 and the slide rail 2;

[0044] At the same time, when the tester body 1 generates heat during operation, the tester body 1 conducts the heat to the heat conducting plate 121 and the heat dissipating fins 122, thereby increasing the heat dissipation area of ​​the tester body 1. At the same time, the setting of the ventilation holes 123 can facilitate the air circulation in the inner cavity of the tester body 1, so that the heat in the inner cavity of the tester body 1 can be discharged in time, thereby effectively improving the heat dissipation effect of the tester body 1 and increasing the service life of the tester body 1.
