During the movement, the protective plate 4 can adjust the height of the storage tank 1 relative to the ground through the first connecting block 9, thereby facilitating the storage tank 1 to receive the transformer cooling oil.

[0067] Embodiment three:

[0068] like Figure 7 as well as Figure 9-12 and Fig.14 As shown, the structure of the transformer cooling oil storage device disclosed in the third embodiment of the present invention is basically the same as that in the second embodiment, except that:

[0069] The side wall of one end of the support leg 5 close to the first connecting block 9 is provided with a limiting hole 20, and the limiting holes 20 are provided in two groups, and the two groups of limiting holes 20 are evenly spaced and distributed in a circumferential state;

[0084] A limiting groove 51 is provided at the center position of the top end of the chamfer block 39, a matching fourth receiving groove 47 is provided at the position of the inner top end of the second receiving groove 40 corresponding to the position of the limiting groove 51, a matching second limiting block 49 is inserted and provided inside the fourth receiving groove 47, a matching fourth elastic member 48 is provided between the top end of the second limiting block 49 and the inner wall of the fourth receiving groove 47, the second limiting block 49 is elastically inserted into the inside of the limiting groove 51 through the fourth elastic member 48, and a third chamfered surface 50 is provided on the side of the second limiting block 49 facing the chamfer block 39;

[0085] A third receiving groove 41 is provided at a position of the side wall of the first connecting block 9 corresponding to the position of the second limiting block 49, a matching first abutting block 42 is inserted and arranged inside the third receiving groove 41, a matching third elastic member 43 is arranged between the side wall of the first abutting block 42 and the inner wall of the third receiving groove 41, the first abutting block 42 is elastically inserted into the inside of the third receiving groove 41 through the third elastic member 43, and a second chamfered surface 44 is provided on the lower end surface of the first abutting block 42 away from the third elastic member 43;

[0086] A first through hole 45 is provided between the third receiving groove 41 and the fourth receiving groove 47. A matching first pull rope 46 is provided inside the first through hole 45. Two ends of the first pull rope 46 are respectively fixedly connected to the lower end surface of the first abutting block 42 and the upper end surface of the second limiting block 49.

[0087] When the protective plate 4 drives the first connecting block 9 to rise, the elastically arranged bevel block 39 will gradually be limited by the bevel groove 38. When the bevel block 39 is squeezed by the bevel groove 38, the gas inside the first airbag 34 will be discharged to the inside of the second airbag 35 through the first exhaust pipe 37. At this time, the second airbag 35 expands and pushes the guide rod 33 to move downward. During the downward movement of the guide rod 33, the second connecting block 29 is driven to move downward. When the second connecting block 29 moves downward, the limiting rod 22 is driven to rotate through the cooperation of the second transmission tooth 30 and the third transmission tooth groove 31, and then the support leg 5 is driven to rotate through the transmission rod 17, so as to adjust the angle between the support leg 5 and the first connecting block 9, and the squeezed bevel block 39 will be limited inside the second receiving groove 40 through the cooperation of the second limiting block 49 and the limiting groove 51.

[0088] The present scheme is specifically as follows: the height of the storage tank 1 is adjusted according to the height of the transformer. When adjusting, the motor 11 is started, and the cooperation between the motor 11 and the adjusting ring 3 drives the supporting rod 7 to rotate inside the supporting groove 8. During the rotation process, the supporting rod 7 drives the lifting rod 58 to move along the inside of the lifting groove 59. During the movement process, the sliding protective plate 4 can be driven to move along the surface of the storage tank 1. During the movement process, the protective plate 4 will drive the first connecting block 9 to move synchronously. When the protective plate 4 drives the first connecting block 9 to rise, the elastically arranged second supporting block 52 will be gradually squeezed by the lower end surface of the second fixing ring 15. When the elastically arranged second supporting block 52 is squeezed, the elastically arranged first limiting block 25 will be driven to shrink toward the inside of the first receiving groove 23 through the second pull rope 56. After the elastically arranged first limiting block 25 withdraws from the inside of the limiting hole 20, the hinge between the supporting leg 5 and the first connecting block 9 will no longer be limited.

[0089] At the same time, the elastically arranged bevel block 39 will gradually be limited by the bevel groove 38. When the bevel block 39 is squeezed by the bevel groove 38, the gas inside the first airbag 34 will be discharged to the inside of the second airbag 35 through the first exhaust pipe 37. At this time, the second airbag 35 expands and pushes the guide rod 33 to move downward. During the downward movement of the guide rod 33, the second connecting block 29 is driven to move downward. When the second connecting block 29 moves downward, the limiting rod 22 is driven to rotate through the cooperation of the second transmission tooth 30 and the third transmission tooth groove 31, and then the supporting leg 5 is driven to rotate through the transmission rod 17, so as to adjust the angle between the supporting leg 5 and the first connecting block 9, so that the supporting leg 5 and the first connecting block 9 are in a vertical state, and the elastically arranged The second abutting block 52 is no longer squeezed at this time, the elastically arranged first limiting block 25 is inserted into the inside of another group of limiting holes 20, and when the chamfered block 39 is squeezed, the elastically arranged first abutting block 42 will no longer be limited by the second fixing ring 15 and pop out, and when the first abutting block 42 pops out, the elastically arranged second limiting block 49 is no longer limited by the first pull rope 46 and pops out, and the squeezed chamfered block 39 will be limited inside the second receiving groove 40 through the cooperation of the second limiting block 49 and the limiting groove 51, ensuring that the second connecting block 29 is limited, and then under the continuous rotation of the abutting rod 7, the height of the storage tank 1 can be adjusted to facilitate the access to the transformer cooling oil;

[0090] After the access is completed, when the storage tank 1 needs to be moved, the motor 11 is started to rotate in the opposite direction. At this time, the height of the storage tank 1 will move down, and the protective plate 4 will move down along the storage tank 1. During the downward movement, the elastically arranged second abutting block 52 is squeezed, so that the first limit block 25 moves out from the inside of the limit hole 20, and then the first connecting block 9 drives the bevel block 39 and the first abutting block 42 to move toward the inside of the through groove 27. When the elastically arranged first abutting block 42 moves to the inside of the through groove 27, it will be squeezed by the through groove 27. At this time, the elastically arranged second limit block 49 moves out from the inside of the limit groove 51. When the bevel block 39 is no longer affected by the second When the limit block 49 is limited, under the action of the second elastic member 36, the second connecting block 29 moves up. At this time, through the cooperation of the limit rod 22, the support leg 5 is driven to rotate, so that a certain angle appears between the support leg 5 and the first connecting block 9. After reaching a certain angle, the elastically set first limit block 25 is inserted into the interior of the limit hole 20 to complete the fixation of the angle between the support leg 5 and the first connecting block 9. When the support leg 5 and the first connecting block 9 have an inclined angle, the height of the storage tank 1 will drop significantly, thereby lowering the center of gravity of the storage tank 1, facilitating the movement of the storage tank 1, and reducing the possibility of the storage tank 1 tilting.
