DETAILED DESCRIPTION

[0025] The present invention is further described in detail below with reference to the accompanying drawings.

[0026] like Figures 1 to 8 As shown, in order to achieve the technical effect of "being able to detect the strength of the transformer casing at a certain temperature", the structure and function of the transformer detection system are described in detail below;

[0027] A transformer detection system includes two support rings 11, each support ring 11 is fixedly connected to a plurality of sliding brackets 12, each sliding bracket 12 is slidably connected to a clamping mechanism 30, each support ring 11 is rotatably connected to a rotating disk 40, and both rotating disks 40 are fixedly connected to a detection mechanism 50; one of the support rings 11 is fixedly connected to a telescopic mechanism I21, and the telescopic end of the telescopic mechanism I21 is fixedly connected to the other support ring 11;

[0028] The clamping mechanism 30 includes a sliding seat 31, a swing motor I 32 is fixedly connected to the sliding seat 31, a swing bracket I 33 is fixedly connected to the output shaft of the swing motor I 32, a swing motor II 34 is fixedly connected to the swing bracket I 33, a swing rod 35 is fixedly connected to the output shaft of the swing motor II 34, a swing motor III 36 is fixedly connected to the swing rod 35, and a clamping bracket 37 is fixedly connected to the output shaft of the swing motor III 36;

[0029] The support ring 11 is fixedly connected with a power mechanism I for driving the rotating disk 40 to rotate;

[0030] The side surface of the clamping bracket 37 is provided with a plurality of grooves;

[0031] The sliding bracket 12 is rotatably connected to a screw rod 13, a sliding seat 31 is slidably connected to the sliding bracket 12, and the sliding seat 31 is connected to the screw rod 13 by threads;

[0032] The sliding bracket 12 is fixedly connected with a power mechanism II for driving the screw rod 13 to rotate;

[0033] The detection mechanism 50 includes a telescopic mechanism II 51, a swing motor IV 52 is fixedly connected to the telescopic end of the telescopic mechanism II 51, and a swing bracket II 53 is fixedly connected to the output shaft of the swing motor IV 52;

[0034] The swing bracket II 53 is fixedly connected with a telescopic mechanism III 54, and the telescopic end of the telescopic mechanism III 54 is fixedly connected with a support plate 55, and the support plate 55 is fixedly connected with a sliding cavity 56, and a plurality of sliding arc plates 57 are slidably connected in the sliding cavity 56, and the plurality of sliding arc plates 57 form a closed loop, and a compression spring I is fixedly connected between the sliding arc plate 57 and the sliding cavity 56, and a temperature control mechanism is provided on the support plate 55;

[0035] The support plate 55 is slidably connected with a sliding column 58, the end of the sliding column 58 is fixedly connected with a detection ball 59, and a compression spring II is fixedly connected between the support plate 55 and the sliding column 58;

[0036] The swing bracket II 53 is fixedly connected with a sensor 510, and the lower end of the sliding column 58 is in contact with the sensor 510;

[0037] When in use, the transformer housing to be tested for strength is placed between the plurality of clamping mechanisms 30, such as Figure 1 As shown, eight clamping mechanisms 30 are provided, and four clamping mechanisms 30 are connected to each support ring 11. The eight clamping mechanisms 30 can fully clamp the transformer housing, and the position of the clamped transformer housing can be adjusted according to different usage requirements, thereby achieving comprehensive detection of the transformer housing;

[0038] When clamping, the power mechanism I is started, the output shaft of the power mechanism I starts to rotate, the output shaft of the power mechanism I drives the screw rod 13 to rotate, and when the screw rod 13 rotates, the sliding seat 31 is driven to move through the thread, thereby adjusting the position of the sliding seat 31, and the swing motor I 32 is started, the output shaft of the swing motor I 32 starts to rotate, and the output shaft of the swing motor I 32 drives the swing bracket I 33 to move, so that the swing bracket I 33 swings, and the swing bracket I 33 drives the swing motor II 34 to move, and the swing motor II 34 drives the swing rod 35 to move, and the swing rod 35 drives the swing motor III 36 to move, and the swing motor III 36 drives the clamping bracket 37 to move, thereby adjusting the position of the clamping bracket 37;

[0039] Start the swing motor I 32, the output shaft of the swing motor I 32 starts to rotate, the output shaft of the swing motor I 32 drives the swing bracket I 33 to swing, the swing bracket I 33 drives the swing motor II 34 to move, the swing motor II 34 drives the swing rod 35 to move, the swing rod 35 drives the swing motor III 36 to move, the swing motor III 36 drives the clamping bracket 37 to move, and then adjusts the angle of the clamping bracket 37;

[0040] Start the swing motor II 34, the output shaft of the swing motor II 34 drives the swing rod 35 to swing, the swing rod 35 drives the swing motor III 36 to move, the swing motor III 36 drives the clamping bracket 37 to move, and then adjusts the angle of the clamping bracket 37;

[0041] like Figure 4 As shown, the output shafts of the swing motor I 32 and the swing motor II 34 are staggered at 90 degrees, so that the output shafts of the swing motor I 32 and the swing motor II 34 can drive the clamping bracket 37 to move to different positions and angles when rotating;

[0042] Furthermore, due to the irregularity of the transformer housing, in order to stably clamp the transformer housing, the swing motor III36 is started, and the output shaft of the swing motor III36 starts to rotate, and the output shaft of the swing motor III36 drives the clamping bracket 37 to swing, so that the clamping bracket 37 swings to different angles, ensuring that the clamping bracket 37 can contact the side of the transformer housing, thereby ensuring the clamping of the transformer housing;

[0043] Further, the telescopic mechanism I21 can be started, and the telescopic mechanism I21 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism I21 drives the sliding bracket 12 to move, thereby adjusting the relative distance between the two sliding brackets 12, so that the clamping mechanisms 30 on the upper and lower sides can move to different positions to meet different clamping requirements;

[0044] Furthermore, the four clamping mechanisms 30 on one side can clamp the transformer housing independently, and the four clamping mechanisms 30 on the upper and lower sides can clamp the transformer housing alternately, thereby ensuring that the two detection mechanisms 50 can detect any position of the transformer housing.

[0045] Further, when the transformer shell is clamped, the telescopic mechanism II51 is started. The telescopic mechanism II51 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism II51 drives the swing motor IV52 to move. The swing motor IV52 drives the swing bracket II53 to move. The swing bracket II53 drives the telescopic mechanism III54, the support plate 55, the sliding cavity 56, the sliding arc plate 57, the sliding column 58, the detection ball 59 and the sensor 510 to move, so that the multiple sliding arc plates 57 are in contact with the side of the transformer shell, one of the two detection mechanisms 50 extends into the inner side of the transformer shell and contacts the inner side of the transformer shell, and the other detection mechanism 50 contacts the outer side of the transformer shell. The contact positions of the two detection mechanisms 50 correspond to each other, that is, one is on the outside and the other is on the inside.

[0046] At this time, in order to adjust the position of the detection mechanism 50, the power mechanism I can be started, the output shaft of the power mechanism I starts to rotate, the output shaft of the power mechanism I drives the rotating disk 40 to rotate, the rotating disk 40 drives the detection mechanism 50 to rotate, the swing motor IV52 is started, the output shaft of the swing motor IV52 starts to rotate, the output shaft of the swing motor IV52 drives the multiple sliding arc plates 57 to move, and then the position of the sliding arc plates 57 is adjusted, so that the sliding arc plates 57 can contact any position of the transformer housing;

[0047] Furthermore, due to the irregularity of the outside and inside of the transformer housing, when the multiple sliding arc plates 57 are in contact with the transformer housing, that is, when the multiple transformer housings are buckled on the outside of the transformer housing, in order to ensure that the multiple sliding arc plates 57 close the contact position of the transformer housing as much as possible, the telescopic mechanism III54 is started. The telescopic mechanism III54 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism III54 drives the multiple sliding arc plates 57 to move, so that the ends of the multiple sliding arc plates 57 are in contact with the transformer housing, thereby forming a relative space.

[0048] The temperature control mechanism provided on the support plate 55 is started. The temperature control mechanism can be a refrigeration mechanism or a heating mechanism, and then the temperature of the transformer shell part which is fastened with multiple sliding arc plates 57 is controlled. At the same time, the telescopic mechanism II51 is started. The telescopic end of the telescopic mechanism II51 pushes the detection ball 59 to contact with the transformer shell, squeezes the transformer shell, and the detection ball 59 feeds back the reaction force of the transformer shell to the sliding column 58. The sliding column 58 contacts the sensor 510 and then feeds back to the sensor 510. The sensor 510 is preferably a pressure sensor, which feeds back the pressure on the transformer shell, so as to detect the strength of the transformer shell at a certain temperature.
