DETAILED DESCRIPTION

[0022] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0023] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0024] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 6 、 Figure 7As shown, a structural diagram of an air-cooled dry-type transformer that is convenient for fixed installation is provided by an embodiment of the present invention, including a base 1 and a transformer body 2, the bottom wall of the transformer body 2 is fixedly installed with a bottom plate 21, the surface of the base 1 is provided with a cylindrical mounting groove 3, the bottom wall of the bottom plate 21 is fixedly installed with a column 4 that cooperates with the mounting groove 3, the side wall of the mounting groove 3 is provided with a positioning mechanism 5 that cooperates with the column 4, the positioning mechanism 5 includes a clamping block 51, a clamping groove 52 and a locking assembly 53, the clamping block 51 is provided with multiple groups and is fixedly installed on the side wall of the column 4 in an annular manner with equal spacing, the clamping groove 52 includes multiple groups of downwardly opened groups on the top wall of the mounting groove 3, which are distributed in an annular manner and cooperate with the clamping block 51 The vertical slot 521 is connected to the mounting slot 3, and the side wall of the mounting slot 3 is provided with a turning slot 522 connected to the bottom end of the vertical slot 521. The bottom wall of the turning slot 522 is downwardly provided with a bottom slot 523 that cooperates with the clamping block 51. The bottom slot 523 and the vertical slot 521 are staggered along the vertical direction. The locking assembly 53 includes a pressing plate 531, a supporting portion 532 and a rotating portion 533. The supporting portion 532 is located on the top wall of the turning slot 522 and is connected to the pressing plate 531. The supporting portion 532 is used to control the pressing plate 531 to be in a vertical state above the clamping block 51. The rotating portion 533 is located on the top wall of the turning slot 522 and is connected to the pressing plate 531. The rotating portion 533 is used to control the pressing plate 531 to rotate to a horizontal state.

[0025] When in use, the transformer body 2 and the bottom plate 21 to be installed are placed on the surface of the base 1, and the column 4 on the bottom wall of the bottom plate 21 is further inserted into the mounting groove 3 on the surface of the base 1. When the column 4 is inserted into the mounting groove 3, the clamping block 51 is synchronously inserted into the vertical groove 521, and the column 4 continues to move into the mounting groove 3, and the clamping block 51 continues to move downward to the bottom of the vertical groove 521. After the clamping block 51 moves to the bottom of the vertical groove 521, the bottom plate 21 is rotated slightly, and the bottom plate 21 drives the column 4 to rotate synchronously, and the column 4 drives the clamping block 51 to move horizontally to the steering groove 522, the clamping block 51 applies a thrust to the pressure plate 531 when moving, so that the pressure plate 531 rotates to a horizontal state, and then the clamping block 51 moves downward into the bottom groove 523. After the clamping block 51 moves into the bottom groove 523, the support portion 532 controls the pressure plate 531 to rotate to a vertical state and restricts the clamping block 51 above the clamping block 51, effectively preventing the clamping block 51 from moving upward. At this time, the column 4 can be stably fixed in the mounting groove 3, and then the transformer body 2 and the bottom plate 21 can be installed on the surface of the base 1. When it is necessary to disassemble the base plate 21 and the transformer body 2, the rotating part 533 controls the pressure plate 531 to rotate to a horizontal state again. At this time, the pressure plate 531 releases the restriction on the clamping block 51 and pulls the base plate 21 upward. The base plate 21 and the column 4 cooperate with each other to drive the clamping block 51 to move upward synchronously into the steering groove 522. The base plate 21 is further rotated. The base plate 21 and the column 4 cooperate with each other to drive the clamping block 51 to move synchronously in the steering groove 522. When the clamping block 51 moves to the bottom end of the vertical groove 521, the base plate 21 is pulled vertically upward. The clamping block 51 moves upward synchronously in the vertical groove 521, and the base plate 21 and the transformer body 2 can be easily removed from the surface of the base 1.

[0026] like Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 As shown, as a preferred embodiment of the present invention, the support portion 532 includes a receiving groove 5321 with an upward opening on the top wall of the turning groove 522, and the pressure plate 531 is rotatably installed at one end of the receiving groove 5321. The top wall of the receiving groove 5321 is provided with a top hole 5322 upward, and an extrusion spring 5323 is fixedly installed in the top hole 5322, and the telescopic end of the extrusion spring 5323 is connected to the side wall of the pressure plate 531.

[0027] Under the action of gravity and the thrust of the extrusion spring 5323, the pressure plate 531 is in a vertical position within the steering groove 522. When the clamping block 51 moves within the steering groove 522, the clamping block 51 can push the pressure plate 531 to rotate to a horizontal position. After the clamping block 51 moves further into the bottom groove 523, the extrusion spring 5323 pushes the pressure plate 531 to a vertical position again. At this time, the pressure plate 531 restrains the clamping block 51 above it, effectively preventing the clamping block 51 from moving upward. When the bottom plate 21 and the transformer body 2 need to be disassembled, the rotating portion 533 controls the pressure plate 531 to rotate to a horizontal position within the steering groove 522. At this time, the pressure plate 531 releases the restraint on the clamping block 51, and can conveniently control the clamping block 51 to move into the steering groove 522 and further into the vertical groove 521.

[0028] like Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 As shown, as a preferred embodiment of the present invention, the rotating part 533 includes a control chamber 5331 with an upward opening on the top wall of the receiving slot 5321, and a motor 5332 is fixedly installed in the control chamber 5331, and a winding roller 5333 is fixedly installed on the output shaft of the motor 5332. A pulling rope 5334 is wound on the surface of the winding roller 5333, and the pulling rope 5334 is connected to the side wall of the pressure plate 531 at one end away from the winding roller 5333. A controller (not shown in the drawings) and a battery (not shown in the drawings) are provided in the base 1, and the battery is used to provide power for the motor 5332, and the controller is electrically connected to the motor 5332.

[0029] When it is necessary to disassemble the base plate 21 and the transformer body 2, the motor 5332 drives the winding roller 5333 to rotate, and the winding roller 5333 reels the pulling rope 5334. The pulling rope 5334 will simultaneously apply tension to the pressure plate 531 during the reeling process, and the pulling rope 5334 will automatically pull the pressure plate 531 to a horizontal state. At this time, the clamping block 51 can move upward to the turning groove 522 and further move to the vertical groove 521, so that the column 4 can be easily removed from the mounting groove 3.

[0030] like Figure 2 、 Figure 6 、 Figure 7 As shown, as a preferred embodiment of the present invention, a sealing component 6 is provided between the base 1 and the bottom plate 21 , and the sealing component 6 is used to seal the gap between the base 1 and the bottom plate 21 .

[0031] like Figure 2 、 Figure 6 、 Figure 7As shown, as a preferred embodiment of the present invention, the sealing assembly 6 includes an annular groove 61 opened on the surface of the base 1 and sleeved on the outside of the mounting groove 3, and a sealing ring 62 that cooperates with the annular groove 61 is fixedly installed on the bottom wall of the base plate 21.

[0032] The transformer body 2 is usually located outdoors. When in a harsh environment such as rain or snow, the sealing ring 62 cooperates with the annular groove 61 to seal the gap between the base 1 and the bottom plate 21, effectively preventing rainwater from flowing into the installation groove 3.

[0033] like Figure 1 、 Figure 2 As shown, as a preferred embodiment of the present invention, a plurality of drain pipes 7 are downwardly opened on the bottom wall of the annular groove 61 , and one end of the drain pipes 7 away from the annular groove 61 extends to the outside of the base 1 .

[0034] like Figure 1 、 Figure 2 As shown, as a preferred embodiment of the present invention, a handrail 8 is provided on the surface of the bottom plate 21 and is located outside the transformer body 2.

[0035] The working principle of the present invention is as follows: when in use, the transformer body 2 and the bottom plate 21 to be installed are placed on the surface of the base 1, and the column 4 on the bottom wall of the bottom plate 21 is further inserted into the mounting groove 3 on the surface of the base 1. When the column 4 is inserted into the mounting groove 3, the clamping block 51 is simultaneously inserted into the vertical groove 521. The column 4 continues to move into the mounting groove 3, and the clamping block 51 continues to move downward to the bottom of the vertical groove 521. After the clamping block 51 moves to the bottom of the vertical groove 521, it is rotated slightly. The base plate 21 drives the column 4 to rotate synchronously, and the column 4 drives the clamping block 51 to move horizontally into the steering groove 522. The clamping block 51 applies a thrust to the pressure plate 531 during movement, causing the pressure plate 531 to rotate to a horizontal position. The clamping block 51 then moves downward into the bottom groove 523. The compression spring 5323 pushes the pressure plate 531 to a vertical position again. At this time, the pressure plate 531 restrains the clamping block 51 above it, effectively preventing the clamping block 51 from moving upward. At this point, the column 4 can be stably fixed in the mounting groove 3, and the transformer body 2 and the base plate 21 can then be mounted on the surface of the base 1.

[0036] When the bottom plate 21 and the transformer body 2 need to be disassembled, the motor 5332 drives the winding roller 5333 to rotate, and the winding roller 5333 rewinds the pulling rope 5334. The pulling rope 5334 will simultaneously apply tension to the pressure plate 531 during the rewinding process, and the pulling rope 5334 will automatically pull the pressure plate 531 to a horizontal state. At this time, the pressure plate 531 releases the restriction on the clamping block 51 and pulls the bottom plate 21 upward. The bottom plate 21 and the column 4 cooperate with each other, which can drive the clamping block 51 to move upward synchronously into the steering groove 522. Further rotate the bottom plate 21, and the bottom plate 21 and the column 4 cooperate with each other, which can drive the clamping block 51 to move synchronously in the steering groove 522. When the clamping block 51 moves to the bottom end of the vertical groove 521, the bottom plate 21 is pulled vertically upward, and the clamping block 51 moves upward synchronously in the vertical groove 521, so that the bottom plate 21 and the transformer body 2 can be easily removed from the surface of the base 1.

[0037] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in this field without departing from the purpose of the present invention.
