Description

Technical Field

[0001] The present invention relates to the technical field of transformer cabinets, and particularly to a heat dissipation cabinet for a transformer. Background Art

[0002] A transformer is a device for changing alternating voltage. During the operation of the transformer, part of the electrical energy is lost in the form of heat, causing the transformer itself to heat up. Therefore, many transformers are directly exposed on the outside and rely on the heat dissipation fins provided on the side for heat dissipation. However, the exposed transformers are vulnerable to corrosion and external force damage, and there are also potential safety hazards of electric shock for the transformers exposed outside. Therefore, a heat dissipation cabinet for a transformer is needed to protect the transformer.

[0003] Although the existing transformer cabinets are provided with a plurality of air inlets and air outlets, in order to prevent dust from entering the inside of the heat dissipation cabinet, dust-proof partitions are also provided. In the daily use of the heat dissipation cabinet, the dust-proof partitions will also reduce the air intake volume of the air inlets, thereby reducing the heat dissipation effect of the heat dissipation cabinet and making it difficult to quickly cool the inside of the heat dissipation cabinet. Therefore, we propose a heat dissipation cabinet for a transformer. Summary of the Invention

[0004] In order to overcome the deficiencies of the prior art, the present invention provides a heat dissipation cabinet for a transformer.

By providing the roller, the friction between the sliding rod and the swing rod can be reduced, and the swing rod can rotate more smoothly.

[0011] As a preferred technical solution of the present invention, the adjusting mechanism includes a connecting rod fixed at the bottom of the side heat dissipation plate and a rack fixed on the lifting rod. A movable gear is provided at one end of the connecting rod away from the side heat dissipation plate. The bottom of the rack is meshed with the outside of the gear.

A connecting shaft is provided in the middle of the assembly block. The top of the flip plate is installed outside the connecting shaft. The convex portion can be supported by the lock block to prevent the side heat dissipation plate from directly contacting the ground and damaging the side heat dissipation plate when it is flipped.

[0018] Compared with the prior art, the beneficial effects that the present invention can achieve are:

[0019] 1. Through the cooperation of structures such as the side heat dissipation plate, the swinging device, the transmission mechanism, and the adjustment mechanism, the connecting rod drives the side heat dissipation plate to flip around the axis of the connecting rod, so that the side heat dissipation plate changes from the vertical state to the horizontal state and then flips upward and resets. At the same time, when the gear drives the side heat dissipation plate to flip upward through the connecting rod, the speed becomes faster, increasing the air circulation speed, increasing the air intake volume, making the air flow speed faster at the ventilation slot, quickly reducing the temperature inside the heat dissipation cabinet body, and improving the heat dissipation efficiency of the heat dissipation cabinet body.

[0020] 2. Through the cooperation of structures such as the rack, the gear, the threaded sleeve, and the pull rod adjustment mechanism, the side heat dissipation plate rotates around the axis of the connecting rod to the horizontal state, making the side heat dissipation plate in an always-open state, thereby avoiding the side heat dissipation plate from blocking the ventilation slot of the heat dissipation cabinet body and increasing the air intake volume inside the heat dissipation cabinet body.

[0021] 3. Through the cooperation of structures such as the side heat dissipation plate and the barrier mechanism, the screen covers between the ventilation slot and the side heat dissipation plate, and the screen isolates sundries to prevent sundries from entering the inside of the heat dissipation cabinet body when the side heat dissipation plate is in the always-open state, causing damage to the transformer.

[0022] 4. Through the cooperation of structures such as the sliding rod, the bidirectional threaded rod, the fixing frame, and the positioning mechanism, the rotation angle of the side heat dissipation plate is adjusted, so as to facilitate people to adjust the flapping amplitude of the side heat dissipation plate, adjust the air intake volume, and thus facilitate people to adjust the air intake volume and the temperature inside the heat dissipation cabinet body when cooling different transformers, which is convenient and fast.

[0033] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments. However, the following embodiments are only the preferred embodiments of the present invention, not all of them. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without creative work all belong to the protection scope of the present invention. The experimental methods in the following embodiments are all conventional methods unless otherwise specified, and the materials, reagents, etc. used in the following embodiments can be obtained from commercial channels unless otherwise specified.

[0034] Embodiment: The present invention provides as Figure 1 , Figure 2 and Figure 8A heat dissipation cabinet for a transformer shown in the figure, comprising:

[0035] A heat dissipation cabinet body 1, a top heat dissipation bin 3 for discharging hot air inside the heat dissipation cabinet body 1 is arranged at the top of the heat dissipation cabinet body 1, an openable cabinet door 2 is further arranged on the front of the heat dissipation cabinet body 1, ventilation slots for facilitating air intake are arranged on both sides of the heat dissipation cabinet body 1, side heat dissipation plates 4 are arranged on the ventilation slots, a plurality of air intake inclined slots are arranged on the side heat dissipation plates 4, a partition frame 7 for separating wire harnesses is further arranged inside the heat dissipation cabinet body 1, and a wire arranging board 8 for fixing the wire harnesses is arranged on the partition frame 7.

[0036] As can be seen from the above, during use, after the transformer is placed inside the heat dissipation cabinet body 1, the wire harness is passed through the partition frame 7 and the wire arranging board 8 for fixing. When the heat dissipation cabinet body 1 is in normal use, cold air enters the inside of the heat dissipation cabinet body 1 through the ventilation slots, and the hot air inside the heat dissipation cabinet body 1 is discharged through the top heat dissipation bin 3, completing the cooling of the temperature inside the heat dissipation cabinet body 1.

[0037] Reference Figures 1-6 As shown in the figure, a swing device 5 is arranged at one end of the heat dissipation cabinet body 1 away from the cabinet door 2. The swing device 5 comprises two motors 501 fixed on the heat dissipation cabinet body 1, two transmission mechanisms are arranged on the output ends of the two motors 501, an adjustment mechanism is arranged between the two transmission mechanisms and the side heat dissipation plate 4, and a positioning mechanism is arranged between the two transmission mechanisms;

[0038] The transmission mechanism comprises a transmission plate 502 fixed on the output shaft of the motor 501 and a sliding rod 507 slidably mounted on the heat dissipation cabinet body 1. A rotatable pulley 512 is arranged at one end of the transmission plate 502 away from the motor 501. A moving disc is arranged at one end of the sliding rod 507 away from the heat dissipation cabinet body 1. A swing rod 503 that can swing is arranged on the moving disc and the pulley 512. A rotatable transmission shaft 513 is arranged at one end of the swing rod 503. A lifting rod 504 is sleeved on the outer wall of the transmission shaft 513. The swing rod 503 is limited by the sliding rod 507, so that the transmission plate 502 drives the swing rod 503 to rotate around the sliding rod 507 through the pulley 512, and the swing rod 503 drives the lifting rod 504 to reciprocate up and down through the transmission shaft 513;

[0039] A fixed block 505 is further fixed on the heat dissipation cabinet body 1. A slot adapted to the lifting rod 504 is opened in the middle of the fixed block 505. A chute adapted to the sliding rod 507 is opened on the heat dissipation cabinet body 1. A roller is fixed at one end of the sliding rod 507 away from the heat dissipation cabinet body 1. A moving slot adapted to the pulley 512 and a positioning slot adapted to the roller are opened on the swing rod 503. By arranging the roller, the friction between the sliding rod 507 and the swing rod 503 can be reduced, and the swing of the swing rod 503 can be made smoother when it rotates.

[0040] The adjusting mechanism includes a connecting rod 506 fixed to the bottom of the side heat dissipation plate 4 and a rack 510 fixed to the lifting rod 504. A movable gear 511 is provided at one end of the connecting rod 506 away from the side heat dissipation plate 4. The bottom of the rack 510 meshes with the outside of the gear 511. The rack 510 is arranged in the lower half of the lifting rod 504, and only half of the teeth are provided on the outer wall of the gear 511.

[0041] By adopting the above technical solution:

[0042] During use, the output shaft of the motor 501 drives the transmission plate 502 to rotate. The transmission plate 502 drives the pulley 512 to rotate. The swing rod 503 is limited by the slide rod 507, so that the pulley 512 drives the swing rod 503 to rotate around the slide rod 507. At the same time, the pulley 512 slides along the moving groove, so that the swing rod 503 drives the transmission shaft 513 to move up and down. The transmission shaft 513 drives the lifting rod 504 to move up and down, so that the lifting rod 504 drives the rack 510 to move up and down, so that the rack 510 drives the engaged gear 511 to rotate. The gear 511 drives the connecting rod 506 to rotate, so that the connecting rod 506 drives the side heat dissipation plate 4 to flip around the axis of the connecting rod 506, so that the side heat dissipation plate 4 changes from the vertical state to the horizontal state and then flips up and resets, pushing the cold air outside the heat dissipation cabinet body 1 into the heat dissipation cabinet body 1, increasing the air intake of the heat dissipation cabinet body 1;

[0043] By rotating the swing rod 503 around the slide rod 507, the swing rod 503 performs a variable-speed reciprocating motion, so that the speed of the swing rod 503 when swinging downward is faster, so that the speed of the swing rod 503 driving the lifting rod 504 to move downward is faster. The lifting rod 504 drives the gear 511 to rotate faster through the rack 510, and the gear 511 drives the side heat dissipation plate 4 to flip upward faster through the connecting rod 506, increasing the air circulation speed, increasing the air intake, making the internal circulation speed of the heat dissipation cabinet body 1 faster, making the air flow speed at the ventilation slot faster, and quickly reducing the temperature inside the heat dissipation cabinet body 1, improving the heat dissipation efficiency of the heat dissipation cabinet body 1.

[0044] Secondly, referring to Figure 1 、 Figure 2 、 Figure 6 and Figure 7 As shown, a threaded portion is provided on the connecting rod 506, and a threaded sleeve 514 is screwed on the threaded portion. Two pull rods 515 are symmetrically fixed on the gear 511, and a groove is provided on the outer wall of the threaded sleeve 514. One end of the pull rod 515 away from the gear 511 is inserted into the groove.

[0045] Two limit blocks are fixed on the outer wall of the connecting rod 506. A jack adapted to the connecting rod 506 is provided in the middle of the gear 511, and a limit groove adapted to the limit block is provided in the jack. Through the cooperation of the limit block and the limit groove, the gear 511 can drive the connecting rod 506 to rotate, and the gear 511 can also move along the outer wall of the connecting rod 506.

[0046] By adopting the above technical solution:

[0047] During use, rotate the threaded sleeve 514 to make the threaded sleeve 514 move along the threaded part of the connecting rod 506. At the same time, the threaded sleeve 514 pushes the pull rod 515 to move, and the pull rod 515 drives the gear 511 to move, so that the gear 511 moves along the outside of the connecting rod 506. After the gear 511 is separated from the rack 510, push the side heat dissipation plate 4 to rotate, so that the side heat dissipation plate 4 rotates around the axis of the connecting rod 506 and turns into a horizontal state, so that the side heat dissipation plate 4 is in an open state all the time, thereby avoiding the side heat dissipation plate 4 from blocking the ventilation slots of the heat dissipation cabinet body 1 and increasing the intake air volume inside the heat dissipation cabinet body 1.

[0048] Again, refer to Figure 1 、 Figure 2 Figure 3 、 Figure 4 and Figure 9 As shown in

[0049] Two barrier mechanisms 6 are provided on both sides of the heat dissipation cabinet body 1. The barrier mechanism 6 includes a screen and a fixing frame. The fixing frame is fixed on the outer wall of the heat dissipation cabinet body 1, and the screen is fixed on the side heat dissipation plate 4.

[0050] A convex portion is provided on the top of the side heat dissipation plate 4. A rotatable lock block 11 is provided on the convex portion. A clamping block is provided at one end of the lock block 11. A flip plate 10 that can be flipped is provided on the heat dissipation cabinet body 1. A clamping groove adapted to the clamping block is provided at the bottom of the flip plate 10.

[0051] By adopting the above technical solution:

[0052] During use, when the side heat dissipation plate 4 is flipped downward, the side heat dissipation plate 4 drives the convex portion to flip downward, so that the convex portion drives the screen to flip downward, so that the screen covers between the ventilation slot and the side heat dissipation plate 4. The screen isolates sundries to avoid sundries from entering the interior of the heat dissipation cabinet body 1 when the side heat dissipation plate 4 is in an open state all the time, causing damage to the transformer;

[0053] When the side heat dissipation plate 4 continuously flaps, the side heat dissipation plate 4 drives the screen to move through the convex part, contracts the screen, and at the same time, the side heat dissipation plate 4 drives the air below the screen to move, blows the sundries on the screen, and makes the sundries on the screen fall outside the screen. This can not only prevent the sundries from accumulating on the screen for a long time and affecting the air intake volume, but also prevent the sundries from damaging the screen.

[0054] Finally, referring to Figures 3-5 As shown, the positioning mechanism includes a fixing frame 509 fixed on the heat dissipation cabinet body 1. A rotatable bidirectional threaded rod 508 is arranged in the middle of the fixing frame 509. A threaded hole adapted to the bidirectional threaded rod 508 is arranged on the sliding rod 507. An adjusting wheel is fixed in the middle of the bidirectional threaded rod 508. An installation groove adapted to the adjusting wheel is arranged in the middle of the fixing frame 509. The outer wall of the adjusting wheel is provided with convex lines facilitating people to rotate the adjusting wheel. The sliding rods 507 on the two transmission mechanisms are both screwed on the bidirectional threaded rod 508.

[0055] By adopting the above technical solutions:

[0056] During use, rotate the adjusting wheel. The adjusting wheel drives the bidirectional threaded rod 508 to rotate. The bidirectional threaded rod 508 drives the sliding rod 507 adapted to it to rotate. The sliding rod 507 is limited by the chute, so that the sliding rod 507 moves along the chute. The sliding rod 507 drives the roller to move along the positioning groove, adjusts the swinging amplitude of the swing rod 503, adjusts the lifting distance of the lifting rod 504, adjusts the rotation angle of the adjusting gear 511, and adjusts the rotation angle of the side heat dissipation plate 4, thereby facilitating people to adjust the flapping amplitude of the side heat dissipation plate 4 and adjust the air intake volume.

[0057] The above has described in detail the embodiments of the present invention with reference to the accompanying drawings. However, the present invention is not limited to this. Within the scope of knowledge possessed by those skilled in the art to which the present invention pertains, various changes can be made without departing from the gist of the present invention.
