[0002] A box-type transformer refers to a traditional transformer installed inside a box, which provides good protection for the transformer and increases the safety of the transformer during use.

[0035] For example, see Figure 1-12 , the present invention provides the following technical solutions:

[0036] A box-type transformer, specifically, comprises a box body 1 and a transformer body slidably arranged on the bottom surface of the box body 1; a maintenance port 2 is provided on the side surface of the box body 1; an annular hollow cavity 3 is provided inside the box body 1; a plurality of coaxial annular grooves 4 are uniformly provided on the inner side surface of the annular hollow cavity 3; a rotating groove 5 connected to the annular hollow cavity 3 is provided on the top of the box body 1; a heat dissipation part 6 is rotatably arranged inside the rotating groove 5; the heat dissipation part 6 comprises an arc box 7 rotatably matched with the annular hollow cavity 3; a rotating ring 8 rotatably matched with the rotating groove 5 is fixed on the arc box 7; the inner side surface of the arc box 7 is uniformly connected to the rotating groove 5; A mounting shell 9 matched with the corresponding annular groove 4 is arranged; a wiping sponge 10 is arranged inside the mounting shell 9; a drain pipe 11 is arranged on the inner peripheral side of the arc box 7 near its top; a first piston cylinder 12 is fixed to the end of the drain pipe 11; a piston part 13 is slidably arranged inside the first piston cylinder 12; an annular water tank 14 coaxial with the box body 1 is fixed to the inner peripheral side of the arc box 7; a water suction pipe 15 is arranged between the first piston cylinder 12 and the annular water tank 14; a screw rod 16 is rotatably arranged through the top of the box body 1; a guide part 17 matched with the piston part 13 is arranged on the screw rod 16.

[0037] Working principle of the first embodiment:

[0038] By controlling the heat dissipation part 6 to perform periodic forward and reverse rotation, the arc box 7 rotates slowly inside the annular hollow cavity 3, driving each group of wet wiping sponges 10 to rotate and wipe the inner wall of the corresponding annular groove 4. The opening of the annular groove 4 increases the heat exchange area of ​​the inner wall of the box body 1, and the heat generated by the operation of the transformer body is transferred to the inner wall of the box body 1. The water retained by wiping the inner wall of the annular hollow cavity 3 is evaporated. This process is an endothermic process, which realizes the heat dissipation inside the box body 1; the guide part 17 is driven by the rotation of the screw rod 16 to perform periodic lifting and lowering movements, and the first piston cylinder 12 is periodically pumped and drained in cooperation with the piston part 13, so as to realize the periodic water supply inside the arc box 7; the guide part 17 is lifted and lowered periodically to drive the second piston plate 71 to lift and lower periodically inside the second piston cylinder 39, so as to draw the heat generated by the operation of the transformer body into the annular hollow cavity 3, thereby improving the water evaporation efficiency.

[0039] For example 2, please refer to Figure 1-12 The second embodiment makes the following improvements on the basis of the first embodiment. Specifically, a U-shaped seat 18 is fixedly installed on the top of the box body 1; a servo motor 19 is fixedly installed on the surface of the U-shaped seat 18; the output end of the servo motor 19 is fixedly connected to the bottom end of the screw rod 16 through a reducer; a driving gear ring 20 is fixed on the side of the screw rod 16; a gear 21 meshing with the driving gear ring 20 is rotatably provided on the top of the box body 1; a driven gear ring 22 meshing with the gear 21 is fixed on the inner side of the annular water tank 14.

[0040] A plurality of ball seats 23 are evenly and fixedly mounted on the bottom surface of the annular water tank 14 ; balls 24 adapted thereto are arranged inside the ball seats 23 .

[0041] A baffle 25 is fixed to the outer side of the first piston cylinder 12; a guide tube 26 is fixed through the side of the baffle 25; the piston part 13 includes a first piston plate 27 that slides with the first piston cylinder 12; a connecting rod 28 is fixed to the side of the first piston plate 27; an ear plate 29 is fixed to the side of the connecting rod 28; a guide rod 30 that slides with the guide tube 26 is fixed to the side of the ear plate 29; a return spring 31 mounted on the guide tube 26 is connected between the ear plate 29 and the baffle 25; and a one-way valve is provided on both the suction pipe 15 and the discharge pipe 11.

[0042] A ball head 32 is fixed to the end of the connecting rod 28; the guide portion 17 includes a threaded sleeve 33 adapted to the screw rod 16; a guide ring 34 coaxial with the threaded sleeve 33 is arranged above the threaded sleeve 33; a conical guide plate 35 is connected between the guide ring 34 and the threaded sleeve 33; an extension plate 36 is fixed to the bottom of the threaded sleeve 33; a vertical rod 37 is fixed to the bottom surface of the extension plate 36; a guide hole 38 slidably matched with the vertical rod 37 is opened on the top of the box body 1.

[0043] Working principle of the second embodiment:

[0044] By setting a one-way valve on the water suction pipe 15, the water inside the annular water tank 14 can only be pumped into the first piston cylinder 12 through the water suction pipe 15. By setting a one-way valve on the drain pipe 11, the water inside the first piston cylinder 12 can only be sent into the arc box 7 through the drain pipe 11.

[0045] The servo motor 19 is controlled to start and drive the screw rod 16 to slowly rotate forward and reverse periodically, and the vertical rod 37 slides freely in the guide hole 38, driving the threaded sleeve 33 to periodically rise and fall along the screw rod 16 seat; in the initial state, the ball head 32 is pressed against the outer peripheral side of the threaded sleeve 33 under the elastic force of the return spring 31. When the threaded sleeve 33 descends, the ball head 32 slides and presses against the outer peripheral side of the guide ring 34 through the tapered guide plate 35. In this process, the ball head 32 is squeezed by the tapered guide plate 35, driving the first piston plate 27 along the first A piston cylinder 12 slides toward the direction approaching the drain pipe 11, the return spring 31 is compressed, and the water inside the first piston cylinder 12 is pressed into the arc box 7 through the drain pipe 11; when the threaded sleeve 33 rises, with the elastic return force of the return spring 31, the ball head 32 slides and presses against the outer peripheral side of the threaded sleeve 33 through the guide slide 34. During this process, the first piston plate 27 slides along the first piston cylinder 12 in the direction away from the drain pipe 11, thereby pumping the water inside the annular water tank 14 into the first piston cylinder 12 through the pumping pipe 15.

[0046] In short, by the periodic forward and reverse rotation of the screw rod 16, the periodic lifting and lowering motion of the guide part 17 is driven, so that the water inside the annular water tank 14 is pumped into the first piston cylinder 12, and is pressed into the interior of the arc box 7 through the first piston plate 27, thereby realizing the automatic supply of water inside the arc box 7 and improving the degree of automation of the device.

[0047] During the rotation of the screw rod 16, the driving ring gear 20 is driven to rotate slowly, thereby driving the gear 21 to rotate slowly, and then driving the driven ring gear 22 to rotate slowly, so that the arc box 7 on the heat dissipation part 6 rotates inside the annular hollow cavity 3, thereby driving the wet wiping sponge 10 to wipe along the corresponding annular groove 4. The moisture after wiping the inner wall of the annular groove 4 is heated and evaporated by the inner wall of the box body 1, completing the heat absorption process and reducing the temperature inside the box body 1; the periodic forward and reverse rotation of the screw rod 16 drives the heat dissipation part 6 to rotate forward and reverse periodically, ensuring that the arc box 7 rotates forward and reverse periodically inside the annular hollow cavity 3 to wipe.

[0048] For example 3, please refer to Figure 1-12 , this third embodiment makes the following improvements on the basis of the second embodiment. Specifically, a second piston cylinder 39 is fixed to the bottom surface of the U-shaped seat 18; a second piston plate 71 that slides with the second piston cylinder 39 is fixed to the bottom of the vertical rod 37; a suction pipe 40 is connected to the bottom of the second piston cylinder 39, and a plurality of delivery pipes 41 are evenly connected to the circumferential side surface near the bottom thereof; each delivery pipe 41 is connected to the annular hollow cavity 3; a one-way valve is provided on the suction pipe 40 and the delivery pipe 41; a coaxial exhaust pipe 42 and an exhaust pipe 43 are symmetrically provided on the outer circumferential side surface of the box body 1; an exhaust fan is provided inside the exhaust pipe 42.

[0049] A plurality of ventilation holes 44 are evenly arranged on the top of the box body 1; a filter plate is installed inside the ventilation hole 44; a threaded groove 45 is arranged on the top of the box body 1; an inner top cover 46 is screwed into the threaded groove 45; an outer top cover 47 coaxial with the inner top cover 46 is fixed on the top; a plurality of ventilation holes 48 are evenly arranged on the side surface of the inner top cover 46.

[0050] Working principle of the third embodiment:

[0051] The periodic forward and reverse rotation of the screw rod 16 drives the guide part 17 to rise and fall periodically, thereby driving the second piston plate 71 to rise and fall periodically along the inside of the second piston cylinder 39. By setting a one-way valve on the suction pipe 40, the hot air inside the box body 1 is drawn into the second piston plate 71 through the suction pipe 40. By setting a one-way valve on each group of delivery pipes 41, the hot air inside the second piston cylinder 39 can only be delivered into the annular hollow cavity 3 through the delivery pipe 41, thereby improving the efficiency of water evaporation and heat absorption inside the annular hollow cavity 3, and further improving the heat dissipation effect inside the box body 1.

[0052] By starting the exhaust fan, external cold air is drawn into the annular hollow cavity 3 through the exhaust pipe 42, and the air after heat exchange is discharged through the exhaust pipe 43, thereby increasing the air flow effect inside the annular hollow cavity 3 and further improving the heat exchange effect.

[0053] The provision of the outer top cover 47 prevents rainwater from directly entering the top of the box body 1 through the inner top cover 46, thereby improving the waterproof effect.

[0054] Example 4, please refer to Figure 1-12 , the fourth embodiment makes the following improvements on the basis of the third embodiment. Specifically, avoidance grooves 49 are symmetrically provided on the outer peripheral side of the box body 1 on both sides of the maintenance port 2; arc grooves 50 are symmetrically provided on the side of the avoidance groove 49; an arc door panel 51 adapted to the avoidance groove 49 is slidably provided on the outer peripheral side of the box body 1; arc rods 52 slidably matched with the corresponding arc grooves 50 are symmetrically fixed on the side of the arc door panel 51; an arc spring is connected between the arc rod 52 and the corresponding arc groove 50; a slot 53 is provided on the outer peripheral side of the arc door panel 51; a plug-in plate 54 plug-in matched with the slot 53 is symmetrically slidably provided on the top of the box body 1; a mounting plate 55 is fixed on the top of the plug-in plate 54; a support spring 56 is symmetrically fixedly connected between the mounting plate 55 and the top of the box body 1; a handle 57 is fixed on the outer peripheral side of the arc door panel 51.

[0055] The bottom of the transformer body is provided with a bearing part 58 by fastening bolts; the bearing part 58 includes a bearing plate 59; the bearing plate 59 is symmetrically fixed with slide rails 60 on two opposite sides; the inner bottom surface of the box body 1 is provided with a sliding cavity 61 that is slidably matched with the bearing plate 59; both sides of the inner wall of the sliding cavity 61 are provided with slide grooves 62 that are slidably matched with the corresponding slide rails 60; the inner bottom surface of the sliding cavity 61 is provided with a receiving groove 63; a limit plate 70 is slidably arranged inside the receiving groove 63; the limit plate 70 is fixedly connected to the receiving groove 63 A first spring is connected; positioning grooves 64 that are plugged into and matched with the limit plate 70 are symmetrically fixed on the surface of the bearing plate 59; guide rods 65 are symmetrically fixed on the surface of the bearing plate 59 on both sides of the positioning grooves 64; a lifting plate 66 is slidably arranged between the two guide rods 65; a second spring 67 that is sleeved on the corresponding guide rod 65 is connected between the lifting plate 66 and the bearing plate 59; a front plate 68 and a rear plate 69 are respectively fixed to the bottom surfaces of the two lifting plates 66; the front plate 68 and the rear plate 69 are respectively plugged into and matched with the corresponding positioning grooves 64.

[0056] Working principle of the fourth embodiment:

[0057] The plug plate 54 is slid upward and pulled out to be pulled out from the corresponding slot 53, the corresponding support spring 56 is compressed, the limit on the sealing door plate 63 is released, and the two sets of arc door plates 51 are squeezed and fitted under the pressure of the corresponding arc springs to complete the closure of the maintenance port 2; when it is necessary to maintain the transformer body inside the box body 1, the plug plate 54 is slid upward and pulled out, and the sealing door plate 63 is rotated to rotate it in the direction away from the limiting plate 70 until the slot 53 is placed directly under the corresponding plug plate 54, and the hand holding the plug plate 54 is released, and the corresponding plug plate 54 is inserted into the corresponding slot 53 under the elastic force of the corresponding support spring 56, so as to achieve fixed limit on the sealing door plate 63, so that the maintenance port 2 is opened.

[0058] In the initial state, the limit plate 70 slides and inserts into the positioning groove 64 just below the front plate 68 under the elastic force of the first spring, completing the fixed limit of the bearing plate 59. In this state, the transformer body is stored inside the box body 1; when the transformer body needs to be maintained, after opening the sealing door panels 63 on both sides, press down the lifting plate 66 corresponding to the front plate 68, drive the front plate 68 to descend and insert into the corresponding positioning groove 64, so that the limit plate 70 is pushed out from the corresponding positioning groove 64, and the limit plate 70 is pushed out of the corresponding positioning groove 64. 0 is kept flush with the bottom surface of the sliding cavity 61, the corresponding second spring 67 and the first spring are both compressed, and the bearing plate 59 is slowly pulled outward to the positioning groove 64 just below the rear plate 69 and slides to just above the limiting plate 70. Under the elastic restoring force of the first spring, the limiting plate 70 is driven to be inserted into the positioning groove 64 just above the rear plate 69, completing the fixed limit of the bearing plate 59. At this time, the transformer body fixedly mounted on the surface of the bearing plate 59 slides out of the box along with the bearing plate 59, which is convenient for subsequent maintenance.

[0059] A method for using a box-type transformer comprises the following steps:

[0060] T1.

[0062] T3. Start the exhaust fan so that external cold air is drawn into the annular hollow cavity 3 through the exhaust pipe 42 and discharged through the exhaust pipe 43, thereby increasing the air flow inside the annular hollow cavity 3 and improving the heat exchange efficiency.
