Specific embodiments
[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0023] The present utility model provides as Figures 1 - 4A locomotive transformer oil acid value measuring instrument shown in the figure includes an acid meter 1. Inside the right front corner at the upper end of the acid meter 1, there is a measurement chamber 2. At the left front corner of the upper end of the acid meter 1, there is a control panel 3. Inside the left side at the upper end of the acid meter 1, there is a printing mechanism 4, and the printing mechanism 4 is located behind the control panel 3. Inside the lower end of the measurement chamber 2, there is a position adjustment turntable 5 rotatably connected. Inside the outer side at the upper end of the position adjustment turntable 5, there are multiple limiting platforms 6 rotatably connected. On the upper side of the rear inner wall of the measurement chamber 2, there is a measurement titration mechanism 7, and the measurement titration mechanism 7 is located above the position adjustment turntable 5 and directly above the last limiting platform 6. At the rear side of the upper end of the measurement chamber 2, there is an upper cover 8 rotatably connected. At the center of the lower end of the position adjustment turntable 5, there is a position adjustment motor 9 rotatably connected through a rotating shaft, and the position adjustment motor 9 is located inside the center of the lower end of the measurement chamber 2. The locomotive transformer oil is measured by the acid value measuring instrument to measure the content of acidic substances in the transformer oil. The aging degree and refining quality of the locomotive transformer oil are evaluated based on the content of acidic substances in the transformer oil to ensure the stable operation of the locomotive transformer. The locomotive transformer oil is placed in multiple measurement containers at a specific weight, and the multiple measurement containers are placed on the upper ends of the multiple limiting platforms 6 for acid value measurement. The multiple measurement containers can be sequentially rotated to directly below the measurement titration mechanism 7 through the position adjustment turntable 5, and the measurement titration mechanism 7 injects liquid and measures the locomotive transformer oil in the measurement container directly below, so as to measure the accurate acid value of the locomotive transformer oil. The measurement result can be printed by the printing mechanism 4, and the position adjustment turntable 5 can accurately rotate the multiple measurement containers to directly below the measurement titration mechanism 7 in sequence through the position adjustment motor 9.
[0024] Preferably, inside the center at the lower end of the limiting platform 6, there is a driven magnetic strip 15. Below the driven magnetic strip 15, there is a driving magnetic strip 16. At the lower end of the driving magnetic strip 16, there is a mixing motor 17 rotatably connected through a rotating shaft, and the mixing motor 17 is arranged at the rear side of the center of the lower inner wall of the measurement chamber 2. During the process of the measurement titration mechanism 7 injecting liquid and measuring the locomotive transformer oil directly below, the measurement container can rotate through the rotation of the limiting platform 6, so as to quickly mix the locomotive transformer oil inside the measurement container and the liquid injected by the measurement titration mechanism 7, thereby ensuring the accurate measurement of the acid value of the locomotive transformer oil. And since the rotating ball 14 and the driving magnetic strip 16 are both magnetic objects, the rotating ball 14 and the driving magnetic strip 16 are magnetically connected. When the driving magnetic strip 16 rotates below the rotating ball 14 through the mixing motor 17, the rotating ball 14 will rotate together with the driving magnetic strip 16 under the action of magnetism, and drive the limiting platform 6 to rotate inside the position adjustment turntable 5, so that the measurement container on the upper end of the limiting platform 6 can follow the rotation, thereby mixing the locomotive transformer oil and the liquid injected by the measurement titration mechanism 7.
[0025] Preferably, a plurality of limiting rotation grooves 10 penetrate through the upper outer side of the upper end of the position-adjusting turntable 5 up and down. And a plurality of limiting platforms 6 are respectively rotatably connected inside the plurality of limiting rotation grooves 10.

A limiting clamping ring 13 is fixedly connected to the outer side of the cylindrical outer wall of the limiting platform 6, and the limiting clamping ring 13 is rotatably connected inside the limiting clamping groove 11.

The limiting platform 6 can be restricted inside the limiting rotation groove 10 through the limiting clamping groove 11 and the limiting clamping ring 13, and restricted inside the position-adjusting turntable 5 through the limiting rotation groove 10. And the limiting clamping ring 13 can rotate inside the limiting clamping groove 11 through the two ball grooves 12 and the plurality of rotating balls 14, thereby reducing the friction between the limiting clamping groove 11 and the limiting clamping ring 13. It can not only make the limiting platform 6 easier to rotate inside the limiting rotation groove 10, but also reduce the wear between the limiting platform 6 and the limiting clamping ring 13 and the position-adjusting turntable 5.
[0026] Preferably, a plurality of clamping sliding grooves 18 are opened inside the outer side of the upper end of the limiting platform 6. A plurality of clamping sliding blocks 19 are slidably connected inside the plurality of clamping sliding grooves 18. One ends of the upper ends of the plurality of clamping sliding blocks 19 close to the central axis of the limiting platform 6 are fixedly connected with clamping claws 20. The upper ends of the clamping claws 20 are arranged in an arc shape, and one end of the clamping claws 20 close to the central axis of the limiting platform 6 is perpendicular to the upper end of the clamping sliding block 19.

A clamping spring 22 is arranged inside one end of the clamping sliding block 19 far away from the central axis of the limiting platform 6. The clamping spring 22 is sleeved outside the limiting rod 21, and the clamping sliding block 19 is elastically connected inside the clamping sliding groove 18 through the clamping spring 22. The measuring container can be clamped to the upper end of the limiting platform 6 through the plurality of clamping claws 20, so that the measuring container can be firmly fixed to the upper end of the limiting platform 6, preventing the measuring container from falling off the upper end of the limiting platform 6 during the rotation process. And the outer walls of the upper ends of the plurality of clamping claws 20 are arranged in an arc shape, making it more convenient for the measuring container to be clamped between the plurality of clamping claws 20. At the same time, the plurality of clamping claws 20 can be elastically connected to the upper end of the limiting platform 6 through the clamping sliding block 19 and the clamping spring 22, enabling the plurality of clamping claws 20 to not only clamp measuring containers of different sizes, but also prevent the measuring container from loosening.
