Description

Technical Field

[0001] The present invention relates to the technical field of detection equipment, and particularly relates to a detection device for transformer manufacturing. Background Art

[0002] The principle of transformer voltage transformation was first discovered by Faraday, but it was not until the 1880s that it began to be practically applied. In the competition between direct current and alternating current that power plants should output, the ability to use transformers for alternating current is one of its advantages. Transformers can convert electrical energy into a high-voltage and low-current form and then convert it back, thus greatly reducing the loss of electrical energy during transmission and enabling the economic transmission distance of electrical energy to be farther.

[0003] In a Chinese patent (application number: CN202123321623.3), a welding detection device for a transformer shell is disclosed, including a base, a fan, and a water tank for accommodating the transformer shell to be detected. The water tank and the fan are both arranged on the base, and the fan is used to dry the transformer shell. It also includes a drying component, and the drying component is arranged on the front side and the rear side of the fan. In the present invention, by arranging the drying component on the front side or the rear side or both the front side and the rear side of the fan, when the fan dries the transformer shell, the temperature of the air blown towards the transformer shell increases, thereby shortening the time for the transformer shell to become dry and improving work efficiency.

[0004] The following technical problems exist in the actual use process of this patent and the prior art:

[0005] 1. When detecting the welding seal of the transformer shell, in order to accurately observe the welding seam of the transformer, it is generally detected by the water detection method, which requires a large amount of time for the operator to dry the transformer shell, reducing the processing efficiency of the transformer. Therefore, it needs to be improved.

[0006] 2. At the same time, since existing transformers generally install a lot of heat sinks for heat dissipation, heat dissipation grooves will be formed between the heat sinks on the transformer shell. If the heat dissipation grooves on the transformer shell are broken due to production errors, it may have a significant impact on the performance, life, and safety of the transformer, and the heat sink grooves of the existing transformer shell are generally difficult to detect. Therefore, it needs to be improved. Summary of the Invention

Specific embodiments

[0028] In order to make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0029] Embodiment 1, as Figures 1-6 shown, a detection device for transformer manufacturing includes a frame 1, a rotatable placement tray 2 is movably installed on the frame 1, a transformer housing 3 is placed on the placement tray 2, a top of the frame 1 is fixedly connected with an imaging device 4, the imaging device 4 is located on the left side of the transformer housing 3, a top of the imaging device 4 is fixedly connected with a connecting block 5, a side of the connecting block 5 is fixedly connected with an electric telescopic rod 6, one end of the electric telescopic rod 6 passes through the connecting block 5 and is fixedly connected with a moving frame 7, a pin row 8 is movably installed inside the moving frame 7, the pin row 8 is composed of multiple groups of pins, adjacent pins are closely attached to each other, a top of the connecting block 5 is fixedly connected with a top plate 9, a pneumatic cylinder 10 is fixedly installed on the top of the top plate 9, and a lower end of the pneumatic cylinder 10 penetrates through the top plate 9 and is fixedly connected with an extrusion box 11.

[0030] When it is necessary to detect the transformer housing 3, the operator can place the transformer housing 3 to be detected on the placement plate 2 at this time, and then start the air cylinder 10 until the air cylinder 10 drives the extrusion box 11 to move into the upper end of the transformer housing 3 and stop. Then, the extrusion box 11 is used to seal the transformer housing 3 and limit the transformer housing 3. Subsequently, by starting the electric telescopic rod 6, the electric telescopic rod 6 drives the moving frame 7 to move towards the transformer housing 3, and then the moving frame 7 drives the pin row 8 to move towards the transformer housing 3, so that the pin row 8 gradually contacts the outer surface of the transformer housing 3 and the pin row 8 is inserted between the heat sinks of the transformer housing 3. Then, the pin row 8 in contact with the transformer housing 3 gradually contracts and moves towards the imaging device 4. At this time, the imaging device 4 can judge whether there is damage between the heat sinks of the transformer housing 3 through the contraction movement of the pin row 8. After that, the operator continues to start the air cylinder 10, so that the air cylinder 10 drives the extrusion box 11 to seal and compress the air inside the transformer housing 3. At this time, if there is a welding seam on the side of the transformer housing 3 in contact with the pin row 8, the air sealed inside the transformer housing 3 will be discharged from the welding seam, and the discharged air will push the pin row 8 to move. At this time, the imaging device 4 can judge the welding seam on the transformer housing 3 through the moving pin row 8. Such a design enables the detection device to detect both the damaged parts between the heat sinks of the transformer housing 3 and the welding seams of the transformer housing 3 without using water, thereby making the detection effect of the detection device on the transformer housing 3 better.

[0031] Embodiment 2, as Figure 4 shown, the imaging device 4 includes an imaging box 401, a camera 402 and a glass screen 403. The imaging box 401 is fixed to the bottom of the connection block 5, the camera 402 is installed inside the imaging box 401, the glass screen 403 is fixed inside the imaging box 401, and the side surface of the glass screen 403 is in contact with the side surface of the pin row 8.

[0032] Through the design of the imaging device 4, the camera 402 can observe the movement of the pin row 8 through the glass screen 403. Then, when the electric telescopic rod 6 drives the moving frame 7 to move towards the imaging device 4, at this time, the glass screen 403 can push the moved pin row 8 into a neat state, so that the neat pin row 8 can continue to test the subsequent transformer housing 3.

[0033] Embodiment 3, as Figure 1 shown, a control box 23 is fixedly connected to the top of the placement plate 2. The top of the control box 23 is fixedly connected to the bottom of the top plate 9. A display screen 24 is fixedly connected inside the control box 23, and the display screen 24 is electrically connected to the imaging device 4.

[0034] Through the relationship between the display screen 24 and the camera device 4, when the camera device 4 detects the damaged parts between the heat sinks of the transformer casing 3 and the welding gaps on the transformer casing 3 through the pin row 8, the data detected by the camera device 4 will be displayed on the display screen 24, so that the operator can quickly find the abnormal parts of the transformer casing 3 and then repair the abnormal parts of the transformer casing 3.

[0035] Embodiment 4, as Figure 2 As shown, a driving motor 13 is fixedly connected to the bottom of the frame 1, and a rotating rod 14 is transmission-connected to the driving motor 13. The upper end of the rotating rod 14 penetrates the frame 1 and is fixedly connected to the bottom of the placement tray 2.

[0036] When the camera device 4 has detected one side of the transformer casing 3 through the pin row 8, the operator can start the drive motor 13 at this time, so that the rotating rod 14 drives the placement plate 2 to rotate, and then the placement plate 2 can drive the transformer casing 3 to rotate ninety degrees, so that the other side of the transformer casing 3 can correspond to the pin row 8, and then start the electric telescopic rod 6, so that the movable frame 7 drives the pin row 8 to detect the heat sink gap on the other side of the transformer casing 3, and then start the pneumatic cylinder 10, so that the pneumatic cylinder 10 drives the extrusion box 11 to compress the air inside the transformer casing 3, and then the air will be discharged from the welding gap of the transformer casing 3, so that the air will push the pin row 8, so that the camera device 4 can detect the welding gap on the other side of the transformer casing 3 through the pin row 8, and then the transformer casing 3 is rotated in turn to detect different surfaces.

[0037] Embodiment 5, as Figure 1 and Figure 3 As shown, an air bag 19 is fixedly connected to the interior of the squeeze box 11 , and the air bag 19 is located above the transformer housing 3 .

[0038] When the airbag 19 is squeezed and expanded by the gas inside the squeeze box 11, the squeeze box 11 can seal and squeeze the transformer casing 3 with different inner diameters through the expanded airbag 19, so that the gas inside the transformer casing 3 is discharged through the welding gap to push the pin row 8, and then the camera device 4 can detect the transformer casing 3 by moving the pin row 8, so that the device can detect the transformer casing 3 with different inner diameters, thereby improving the detection range of the transformer casing 3 by the device.

[0039] Embodiment six, as Figure 3As shown in the figure, a blower 15 is fixedly connected to the top of the top plate 9. An air extraction pipe 16 is fixedly installed at the upper end of the blower 15, and an air delivery pipe 18 is fixedly installed at the lower end of the blower 15. The lower end of the air delivery pipe 18 penetrates through the top plate 9 and extends to the outside of the top plate 9. A connecting pipe 17 is movably sleeved inside the lower end of the air delivery pipe 18, and the lower end of the connecting pipe 17 is fixedly communicated with the extrusion box 11.

[0040] By starting the blower 15, the air extraction pipe 16 extracts the external air, and then the air delivery pipe 18 discharges the air into the inside of the extrusion box 11 through the connecting pipe 17, so that the air inside the extrusion box 11 gradually compresses and expands the air bag 19, and then the extrusion box 11 can seal and contact the inner wall of the transformer shell 3 through the expanded air bag 19, thus achieving the purpose of sealing the transformer shells 3 with different inner diameters.

[0041] Embodiment Seven, as Figure 6 As shown in the figure, a side pipe 20 is fixedly communicated with the air delivery pipe 18. The other end of the side pipe 20 is fixedly connected with a valve 21, and the other end of the valve 21 is fixedly communicated with an exhaust pipe 22.

[0042] When discharging the air inside the extrusion box 11, at this time, by opening the valve 21, the air inside the extrusion box 11 will sequentially pass through the connecting pipe 17 and the air delivery pipe 18 and be discharged to the side pipe 20, and then the air will be discharged from the exhaust pipe 22, thus achieving the purpose of discharging the air inside the extrusion box 11.

[0043] Embodiment Eight, as Figure 5 As shown in the figure, a plurality of balls 12 are equidistantly installed inside the placement plate 2, and the upper ends of the balls 12 are in contact with the bottom of the transformer shell 3.

[0044] When limiting the transformer shell 3 on the placement plate 2, at this time, the operator can more easily move the transformer shell 3 to directly below the extrusion box 11 through the balls 12, and then by starting the air cylinder 10, the air cylinder 10 drives the extrusion box 11 to move into the inside of the transformer shell 3. Subsequently, by starting the blower 15, the air extraction pipe 16 extracts the external air, and then the air delivery pipe 18 discharges the air into the inside of the extrusion box 11 through the connecting pipe 17, so that the air inside the extrusion box 11 gradually expands the air bag 19, and then the extrusion box 11 can push the transformer shell 3 to move through the expanded air bag 19. At this time, the transformer shell 3 can move better through the balls 12.
