Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0031] For ease of understanding, please refer to Figures 1 to 4 , this embodiment provides an electric power oil detection device, including a detection box 1. Inside the detection box 1, there is a filter cylinder 2 for filtering impurities in the electric power oil to be detected. A plurality of filter holes are formed in the peripheral wall of the filter cylinder 2. The filter cylinder 2 is drivingly connected to a rotation mechanism 8. The rotation mechanism 8 can drive the filter cylinder 2 to perform a vertical flipping motion inside the detection box 1. The filter cylinder 2 is rotatably connected to an oil inlet pipe 3 for conveying the electric power oil into the filter cylinder 2. The inlet end of the oil inlet pipe 3 is clamped on the support arm 4 of the detection box 1. Below the inside of the detection box 1, there is a detection sensor 5 for detecting the quality of the electric power oil. The detection sensor 5 is electrically connected to a control panel 6 located outside the detection box 1. Below the detection box 1, there is an oil outlet 7, and the opening and closing state of the oil outlet 7 is controlled by a valve.

[0032] The staff conveys the electric power oil to be detected into the filter cylinder 2 through the oil inlet pipe 3, and starts the rotation mechanism 8 to drive the filter cylinder 2 to perform a vertical flipping motion, so that the filter cylinder 2 continuously rotates while filtering the electric power oil, avoiding the impurities in the electric power oil from clogging the filter holes for a long time, affecting the filtering effect and prolonging the filtering time. After the electric power oil filtered by the filter cylinder 2 overflows from the filter holes, it flows down to the lower part of the detection box 1. The quality of the electric power oil is detected by the detection sensor 5. The detection sensor 5 analyzes and processes the data of the electric power oil, and displays the detection result on the control panel 6 outside the detection box 1, so as to determine whether the batch of electric power oil meets the relevant regulations and requirements.

[0033] For ease of understanding, please refer to Figures 1 to 3The rotating mechanism 8 includes a funnel-shaped rotating member 81 which is rotatably connected to the side wall of the detection box 1 through a rotating bearing. The wide end of the rotating member 81 is detachably connected to the filter cartridge 2, and the narrow end of the rotating member 81 is rotatably connected to the outlet end of the oil inlet pipe 3 through a rotating joint 9. A driving assembly for driving the rotating member 81 to flip vertically is connected to the narrow end of the rotating member 81 located outside the detection box 1, which includes a motor box 82 fixed to the outside of the detection box 1. A motor is arranged in the motor box 82. The output shaft of the motor passes through the motor box 82 and is connected to one end of a worm 83. The other end of the worm 83 is rotatably connected to the extension plate 85 of the detection box 1. The upper part of the worm 83 is meshed with a worm wheel 84, and the inner side of the worm wheel 84 is connected to the rotating member 81. When the motor is turned on, the output shaft of the motor drives the worm 83 to rotate, and the rotation of the worm 83 drives the meshing worm wheel 84 above to rotate, and the rotation of the worm wheel 84 drives the rotating member 81 located inside the worm wheel 84 to rotate, and finally the rotation of the rotating member 81 drives the filter cartridge 2 to flip vertically.

[0034] For easier understanding, see Figures 2 to 4 A screw hole 22 is provided on the end of the peripheral wall of the filter cartridge 2, and a corresponding screw hole 22 is provided on the wide end of the rotating member 81. The screws are inserted into the screw holes 22 of the filter cartridge 2 and the rotating member 81 in sequence to achieve relative fixation of the filter cartridge 2 and the rotating member 81. A first groove 21 is provided on the end of the peripheral wall of the filter cartridge 2, and a protrusion 811 is provided on the wide end of the rotating member 81. When the filter cartridge 2 is installed on the rotating member 81, the positions of the screw holes 22 of the filter cartridge 2 and the rotating member 81 can be aligned by correspondingly plugging the positions of the first groove 21 and the protrusion 811, which is convenient for the staff to install and improves the assembly efficiency. The detection box 1 is screwed with a support rod 11 on the side wall of the mirror image side of the rotating mechanism 8. The support rod 11 penetrates the side wall of the detection box 1 from the outside of the detection box 1 and enters the inside of the detection box 1, and extends to the second groove 23 at the bottom of the filter cartridge 2. The support rod 11 can support the filter cartridge 2, so that the filter cartridge 2 is always in a horizontal state during the vertical flipping process, avoiding tilting after long-term filtration, ensuring that the rotating mechanism 8 can operate normally and drive the filter cartridge 2 to flip vertically. A wear-resistant ring 12 is nested inside the second groove 23. The wear-resistant ring 12 is made of a material with high wear resistance, such as polyurethane rubber. The support rod 11 is sleeved on the inner side of the wear-resistant ring 12, and the support rod 11 is rotatably connected to the filter cartridge 2 through the wear-resistant ring 12. A sealing ring is provided at the connection between the support rod 11 and the side wall of the detection box 1 to prevent oil leakage. A box cover 10 is screwed on the top of the detection box 1.

[0035] When the staff installs the filter cartridge 2, first, align the first groove 21 at the end of the circumferential wall of the filter cartridge 2 with the position of the protrusion 811 at the wide end of the rotating member 81. After sleeving the filter cartridge 2 on the rotating member 81, relatively fix the filter cartridge 2 and the rotating member 81 with screws. Then, align the support rod 11 with the position of the second groove 23 at the bottom of the filter cartridge 2, and insert it through the outside of the detection box 1 until the support rod 11 abuts against the bottom of the filter cartridge 2. At this time, the support rod 11 and the filter cartridge 2 are rotationally connected through the wear-resistant ring 12. Then, connect and fix the support rod 11 and the side wall of the detection box 1 with screws. Finally, cover the box cover 10 and lock it with screws, thus completing the installation action of the filter cartridge 2; after the detection device is used multiple times, it is necessary to disassemble the filter cartridge 2 to clean the impurities inside the filter cartridge 2. First, disassemble the box cover 10. After sequentially disassembling the fixing screws of the support rod 11 and the side wall of the detection box 1, horizontally pull out the support rod 11 from the detection box 1. Then, after sequentially disassembling the fixing screws of the filter cartridge 2 and the rotating member 81, horizontally pull the filter cartridge 2 away from the rotating member 81, thus completing the disassembly action of the filter cartridge 2.

[0036] Although the present utility model has been described by using the above preferred embodiments, it is not intended to limit the protection scope of the present utility model. Any person skilled in the art, without departing from the spirit and scope of the present utility model, making various changes and modifications to the above embodiments still belongs to the protection scope of the present utility model.
