[0033] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0034] like Figure 1-4 As shown, the utility model provides a high-frequency electronic transformer, which includes: a base 1, a fixing component 2, a heat dissipation component and a transformer body 8;

[0035] The transformer body 8 is fixed on the base 1, and the heat dissipation assembly includes: an air intake pump 1001 and a heat conduction plate 1002; wherein,

[0036] At least two heat-conducting plates 1002 with hollow structures are vertically fixedly arranged on the inner wall of the shell of the transformer body 8, and each of the heat-conducting plates 1002 is evenly provided with a plurality of air outlet pipes 12 connected with the inside thereof and capable of passing through the shell of the transformer body 8. The inside of the base 1 is a hollow structure, and an air intake pump 1001 is fixedly arranged therein. The output end of the air intake pump 1001 is connected with the inside of each transformer body 8 through an air intake pipe 11, and the input end thereof passes through the base 1;

[0037] At least two groups of fixing components 2 with adjustable intervals are fixedly arranged on the base 1 to assemble the transformer body 8 on an outdoor angle iron bracket.

[0038] In the above scheme, when the heat generated inside the transformer body 8 is conducted to the heat conducting plate 11, and the air intake pump 1001 works to inject external air into the heat conducting plate 11 through the air intake pipe 11, and the gas passing through the heat conducting plate 11 exchanges heat with the heat conducting plate 11, so as to indirectly cool the inside of the transformer body 8, and the gas after heat exchange is discharged into the external environment through the air outlet pipe 11. Therefore, the heat generated inside the transformer body 8 can be heat exchanged with the external air through the heat dissipation component 3 to achieve heat dissipation. Moreover, during the heat dissipation process, the outside air enters the heat conducting plate 11 through the air inlet pipe 11, and is discharged from the air outlet pipe 12 after heat exchange with the heat conducting plate 11, so that the outside air will not contact the coil and the iron core of the transformer body 8. Therefore, even if the outside air contains moisture or dust, it will not affect the normal use of the coil and the magnet inside the transformer body 8. While dissipating the heat, it can play a dustproof and waterproof role, preventing dust and moisture from entering the shell of the transformer body 8 and contacting the coil and the iron core to corrode the coil and the iron core, affecting their normal use.

[0039] The transformer housing of the prior art is provided with multiple rows of heat dissipation fins, and the heat generated inside the transformer is conducted to the external environment through the heat dissipation fins. Compared with the prior art heat dissipation technology, the present embodiment uses the flowing gas to enter the heat conducting plate 1001 and flow out from the inside thereof, so that the heat on the heat conducting plate 1001 is continuously driven by the flowing gas, thereby improving the heat dissipation effect.

[0040] In the above solution, the heat conducting plate 1002 is fixed on the inner wall of the shell of the transformer body 8, and the side of the heat conducting plate 1002 facing away from the inner wall of the shell can be in contact with the heat generating component of the transformer body 8 (or the transformer body 8 is installed between two heat conducting plates 1002), so that the heat generated by the heat generating component of the transformer body 8 is transferred to the heat conducting plate 1001. The heat conducting plate 1001 can be made of aluminum or other heat conducting materials.

[0041] In a preferred embodiment of the present invention, each set of the fixing components 2 comprises: a moving plate 201 and a clamping plate 202; wherein,

[0042] Two movable plates 201 that can move horizontally toward the base 1 and can be locked by the locking mechanism 3 after movement are symmetrically arranged on both sides of the base 1 located on both sides of the transformer body 8, and the facing surfaces of the two movable plates 201 located below the base 1 are respectively spaced apart and horizontally fixed with clamping plates 202 that can rest against the inside of the angle iron.

[0043] In the above scheme, if Figure 1 As shown, by moving the two movable plates 201 of each group of the fixed components 2 toward each other, the two movable plates 201 drive the clamping plates 202 on each of them to approach the angle iron until the clamping plates 202 abut against the angle iron, and the moved movable plates 201 are locked and fixed by the locking mechanism 3.

[0044] In the actual installation process, at least two angle irons are installed between two electric poles, and the transformer is placed on multiple angle irons, and the transformer is installed on the angle irons by bolts. The bolt installation method requires that the bolts be fixed one by one on the transformer and the angle irons, which is time-consuming and inconvenient for maintenance. Compared with the existing assembly method, the present embodiment can quickly install the transformer on the angle iron through the fixing component 2, which is simple and fast to operate, improves installation efficiency, and facilitates maintenance.

[0045] In a preferred embodiment of the present invention, the locking mechanism 3 comprises: a first tooth plate 301, a second tooth plate 302 and a locking tooth plate 303; wherein,

[0046] A first tooth plate 301 and a second tooth plate 302 are symmetrically and movably provided at the upper end of the base 1 located on both sides of the transformer body 8, and the first tooth plate 301 and the second tooth plate 302 are respectively fixed on the two clamping plates 202 of each group of the clamping plates 202, and a locking tooth plate 303 that can be meshed and connected with the first tooth plate 301 and the second tooth plate 302 is liftably provided above the first tooth plate 301 and the second tooth plate 302.

[0047] In the above scheme, when in use, the locking tooth plate 203 is moved upward to separate it from the first tooth plate 301 and the second tooth plate 302 respectively to disengage the meshing relationship, and then the spacing between the two movable plates 201 is adjusted so that the two clamping plates 202 on the two movable plates 201 are against the angle iron, and the base 1 and the transformer body 8 fixed on the base 1 are firmly fixed on the angle iron bracket. After the movable plate 201 is moved to a suitable position, the locking tooth plate 303 is lowered in the vertical direction until it is meshed and connected with the first tooth plate 301 and the second tooth plate 302 respectively, thereby locking and fixing the movable plate 201 after moving.

[0048] In a preferred embodiment of the present invention, a row of limit columns 4 are evenly spaced and vertically fixed on the base 1 located next to each of the locking tooth plates 303, and a row of limit plates 5 corresponding to the row of limit columns 4 are horizontally fixed on each of the locking tooth plates 303 near the row of limit columns 4, and each of the limit plates 5 is vertically penetrated with a guide hole for the corresponding limit column 4 to pass through, and each of the limit columns 4 located above each of the limit plates 5 is sleeved with a tensioning spring 6, and the two ends of each of the tensioning springs 6 are respectively fixed on the limit plates 5 and the top of the limit columns 4.

[0049] In the above scheme, through the tensioning action of multiple tensioning springs 6, the locking tooth plate 303 can be pressed against the first tooth plate 301 and the second tooth plate 302, and meshed with the two to achieve a locking function. When the locking relationship needs to be released, it is only necessary to pull the locking plate 303 upwards and overcome the force of the tensioning spring 6, so that the locking plate 303 is disengaged from the first tooth plate 301 and the second tooth plate 302, thereby moving the movable plate 201.

[0050] In a preferred embodiment of the present invention, a magnetic block 9 is fixedly disposed on each of the clamping plates 202 facing the base 1 .

[0051] In the above scheme, when the clamping plate 303 abuts against the angle iron, since the angle iron is made of iron material, the clamping plate 303 can be tightly adsorbed on the angle iron under the magnetic force of the magnetic block 9, further improving the fixing effect of the fixing component 2.

[0052] In a preferred embodiment of the utility model, the side wall of the base 1 is provided with a maintenance port connected to the interior thereof, and a sealing plate capable of covering the maintenance port is detachably provided on the maintenance port, and the input end of the air intake pump 1001 passes through a through hole on the sealing plate.

[0053] In the above solution, when the air intake pump 1001 is not working, the air intake pump 1001 can be taken out for maintenance through the maintenance port.

[0054] In a preferred embodiment of the present invention, a guide rail 7 is horizontally fixedly provided on the upper end of the base 1 directly below each of the locking tooth plates 303, and the bottoms of the No. 1 tooth plate 301 and the No. 2 tooth plate 302 are partially recessed to form a No. 1 slide groove and a No. 2 slide groove that are compatible with the guide rail 7, and the No. 1 tooth plate 301 and the No. 2 tooth plate 302 are slidably assembled on the guide rail 7 through the No. 1 slide groove and the No. 2 slide groove.

[0055] In the above scheme, through the coordinated use of the guide rail 7 and the first tooth plate 301 and the second tooth plate 302, it can be ensured that the two movable plates 201 of each group of the fixed assembly 2 can move smoothly and reliably.

[0056] In summary, the high-frequency electronic transformer provided by the utility model overcomes the problem in the prior art that the heat generated by the electronic transformer body is only transferred to the external environment through a heat conducting plate or a heat conducting block, the heat dissipation effect is not very good, and the service life of the electronic transformer is reduced.
