[0028] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0029] The outer box of the box transformer is mainly composed of a box body and a door panel component 400. The door panel component 400 usually includes a door panel body 410, a crossbeam 420 and two door posts 430. The crossbeam 420 is installed above the door panel, and the two door posts 430 are symmetrically arranged on both sides of the door panel body 410. For some box transformers with door sealing requirements, the door panel body 410 is fixed relative to the crossbeam 420 and the door posts 430. However, with the increasing urban electricity load, the outer dimensions of the box transformer are also increasing. The door panel body 410 of some box transformer outer boxes has already exceeded the prescribed maximum limit size, and even the door panel body 410 is too long and deformed. In addition, the door panel components 400 of some box transformers built in the early stage are standardized components. If the length of the door panel body 410 is continuously increased with the requirements of the box transformer, it is extremely unfavorable for the standardized production and processing of the door panel body 410, which will lead to overly complicated production and processing processes, difficult installation and transportation, and a significant increase in labor costs, production costs and transportation costs. In severe cases, the outer box of the box transformer is deformed and the internal components are damaged.

[0030] Reference Figure 1 As shown, a box-type transformer door sealing device according to an embodiment of the utility model comprises a rectangular door sealing plate 100 made of stainless steel. The door sealing plate 100 is horizontally arranged and perpendicular to the horizontal plane, that is, the two long sides of the door sealing plate 100 are spaced apart in the vertical direction, and the two short sides are spaced apart in the horizontal direction. The edges of the two long sides are respectively provided with a first transition section 110 formed by bending backwards, and the edges of the two short sides are respectively provided with a second transition section 120 formed by bending backwards, and the first transition section 110 and the second transition section 120 are both perpendicular to the door sealing plate 100.

[0031] Reference Figure 1 and Figure 2 As shown, it can be understood that the outer edge of the second transition section 120 is provided with a first connecting portion 111 which is vertically bent in a direction away from the center of the door closing plate 100, and the first connecting portions 111 of the two second transition sections 120 are symmetrically arranged on both sides of the door closing plate 100 and parallel to the door closing plate 100, and the first connecting portion 111 is provided with a first through hole 1101 for connecting the door column 430.

[0032] The first connection part 111 is bolted to the door column 430 through the first through hole 1101, so that the two sides of the door plate 100 are fixed to the two door columns 430 respectively. The cooperation between the first connection part 111 and the door column 430 can play a major role in fixing the door plate 100, ensuring that the door plate 100 is installed stably. At the same time, the first connection part 111 is formed by bending backward and the outer edge of the first connection part 111 is bent outward twice. After the door plate 100 is fixed, the first connection part 111 can be hidden behind the door column 430, thereby reducing the contact between the bolts on the first connection part 111 and the outside world, increasing the bending section, ensuring the neat appearance of the outer box of the box transformer, and extending the service life of the box transformer door sealing device.

[0033] Reference Figure 2 It can be understood that there are multiple first through holes 1101, and the multiple first through holes 1101 are arranged at intervals along the vertical direction. By providing multiple first through holes 1101, the door sealing plate 100 can be fixed at multiple points on the side of the door sealing plate 100, further improving the installation stability of the door sealing plate 100 and enhancing the sealing effect of the door sealing plate 100.

[0034] Reference Figure 2 and Figure 3 It can be understood that the outer edge of the first transition section 110 located at the top is provided with a second connecting portion 121 bent downward (i.e., in the direction toward the center of the door-sealing plate 100), and the second connecting portion 121 is provided with a second through hole 1201 for connecting the crossbeam 420, and the outer edge of the first transition section 110 located at the bottom is provided with a third connecting portion 122 bent downward (i.e., away from the center of the door-sealing plate 100), and the third connecting portion 122 is provided with a third through hole 1202 for connecting the door panel body 410, and the second connecting portion 121 and the third connecting portion 122 are both parallel to the door-sealing plate 100, that is, the first connecting portion 111, the second connecting portion 121 and the third connecting portion 122 are all bent 90°, thereby ensuring the structural consistency of the box-type transformer door-sealing device and facilitating the bending processing of the box-type transformer door-sealing device.

[0035] Specifically, when assembling the door panel component 400 of the box transformer, the user can rivet the second connection part 121 to the crossbeam 420 through the second through hole 1201, thereby installing the door plate 100 on the crossbeam 420. The cooperation between the second connection part 121 and the crossbeam 420 can play a secondary role in fixing the door plate 100; the user can then bolt the third connection part 122 to the door panel body 410 through the third through hole 1202, which plays an auxiliary role in fixing the door plate 100, ensuring the sealing effect of the door plate 100 while improving the overall structural tightness of the door panel component 400. In addition, the second connection part 121 and the third connection part 122 formed by the secondary bending are both hidden on the rear side of the door panel component 400, which can further improve the neatness of the box transformer's appearance and extend the service life of the box transformer's door sealing device.

[0036] Among them, the first through hole 1101 and the third through hole 1202 are both slot-shaped holes set in the horizontal direction or in the vertical direction. The first through hole 1101 is set as a slot-shaped hole to reserve fine-tuning space for the box-type transformer door sealing device, so that when the user assembles the door sealing plate 100, the door sealing plate 100 can be slightly moved, and the second through hole 1201 is aligned with the rivet hole on the crossbeam 420 without affecting the bolt connection between the first connecting part 111 and the door column 430; the third through hole 1202 is set as a slot-shaped hole to ensure that the adjusted door sealing plate 100 can also be smoothly connected to the door panel body 410. The first through hole 1101 cooperates with the third through hole 1202, which is convenient for the user to adjust the door panel position and then assemble the door sealing plate 100, eliminate the matching error of the door panel component 400 caused by factors such as processing accuracy, and effectively improve the fault tolerance rate of the door sealing plate 100.

[0037] Reference Figure 2 As shown, it can be understood that the rear side wall of the door closing plate 100 is connected to a wire trough mounting frame 300, and the wire trough mounting frame 300 is a bent piece with both sides bent vertically forward, and an installation groove 301 for installing the wire trough is formed between the wire trough mounting frame 300 and the door closing plate 100, and the wire trough mounting frame 300 is also provided with a threading hole connected to the installation groove 301 for the cable to pass through.

[0038] By setting the wire trough mounting frame 300, the user can fix the wire trough inside the box transformer through the wire trough mounting frame 300, which is convenient for wiring after assembly, reduces the user's high-altitude operation time, and improves the convenience of assembly of the box transformer as a whole. In addition, the user can set a corresponding number of wire trough mounting frames 300 according to the number of wire troughs that need to be fixed, and multiple wire trough mounting frames 300 can be arranged at intervals in the horizontal direction to ensure that the internal lines of the box transformer are clear and convenient for wiring.

[0039] The front end surface of the wire trough mounting frame 300 is welded and fixed to the door sealing plate 100, and the bottom of the wire trough mounting frame 300 is welded and fixed to the top end surface of the third connecting portion 122. The wire trough mounting frame 300 is welded and fixed to the door sealing plate 100 and the top end surface of the third connecting portion 122 respectively, which can effectively improve the structural stability of the wire trough mounting frame 300. At the same time, the wire trough mounting frame 300 can also play a role similar to a reinforcing rib to strengthen the structural strength between the door sealing plate 100 and the third connecting portion 122.

[0040] Since the third connecting portion 122 is formed by folding the second connecting section backward, and along the front-to-back direction, the thickness of the door panel main body 410 is generally smaller than the width of the second connecting section, if the door panel main body 410 is forcibly bolted to the third connecting portion 122, it is easy for the door panel main body 410 to be recessed into the cross beam 420 and the door column 430, that is, along the front-to-back direction, there is a certain distance between the front end surface of the door panel main body 410 and the front end surfaces of the cross beam 420 and the front end surfaces of the door column 430, which affects the beautiful appearance of the box-type transformer and easily makes it inconvenient to disassemble and assemble the door panel main body 410.

[0041] Reference Figure 3 It can be understood that the outer edge of the third connecting portion 122 is provided with a hook portion 123 formed by vertically bending forward, and the end of the hook portion 123 away from the second connecting portion 121 is vertically bent upward to form a limiting portion 124. After the door closing assembly is assembled, the limiting portion 124 abuts against the door panel body 410.

[0042] By setting the limiting portion 124, the limiting portion 124 can limit the movement of the door panel body 410 along the front and rear directions, so as to prevent the door panel from being recessed relative to the cross beam 420 and the door column 430, and keep the front end surface of the door panel body 410 flush with the front end surface of the cross beam 420 and the front end surface of the door column 430, thereby further improving the appearance of the box-type transformer and ensuring the convenience of assembly of the door panel body 410.

[0043] Reference Figure 4 and Figure 5 It can be understood that since the box-type transformer door sealing device is made of a stainless steel door sealing plate 100 using a multi-stage bending process, the user can control the length and width of the door sealing plate 100 when it is not bent, as well as the length and width of the bent part during bending, thereby controlling the length and various height dimensions of the box-type transformer door sealing device after bending, that is, the door sealing plate 100 has various length dimensions and various height dimensions.

[0044] It can be understood that by setting up the door sealing device, the user can produce the door panel parts 400 such as the door panel main body 410, the crossbeam 420, and the door column 430 according to standardized specifications in advance. When assembling the transformer outer box, the user bends the door sealing panel 100 according to actual needs and controls the length and height of the damper plate, so that the length and width of the door sealing panel 100 are lengthened or shortened to appropriate values, and then the door column 430 is connected through the first through hole 1101 of the first connecting part 111, the crossbeam 420 is connected through the second through hole 1201 of the second connecting part 121, and the door panel is connected through the third through hole 1202 of the third connecting part 122, so as to ensure that the transformer door sealing device can adapt to transformer outer boxes of different lengths or different widths.

[0045] Since the box-type transformer door sealing device is formed by bending a door sealing plate 100 made of stainless steel, it can not only effectively improve the overall structural strength of the box-type transformer door sealing device and extend the service life of the box-type transformer door sealing device; moreover, compared with the simple structure of the traditional integrated door panel, the box-type transformer door sealing device with the bending process has a simpler structure and is more convenient to produce and assemble, which can greatly reduce the production time; and the box-type transformer door sealing device can facilitate the standardization of door panels, and the user can produce the door panel components 400 in advance to reserve inventory. All that is needed is to produce the box-type transformer door sealing device of the corresponding size, and then use it by cooperating with the door panel components 400 through the various through holes, which greatly improves the manufacturing efficiency of the door panel components 400.

[0046] Reference Figure 1 It can be understood that the front side wall of the door plate 100 is connected with a rain shield 200. Specifically, the rain shield 200 is welded and fixed to the front side wall of the plate through the fourth connection part 220 on the rear side. The rain shield 200 is located at the lower part of the door plate 100 and above the third connection part 122. The rain shield 200 is extended in the direction away from the door plate 100. In the horizontal direction, the length of the rain shield 200 is greater than or equal to the length of the door plate 100. By setting the rain shield 200 with a length greater than or equal to the length of the door plate 100, the rain shield 200 can block rainwater and prevent rainwater from entering the box transformer through the gap between the second transition section 120 below and the door plate body 410, thereby playing a role in rainproof and waterproofing, and enhancing the rainproof effect and structural strength of the box transformer.

[0047] Reference Figure 3 It is understandable that the end of the rain shield 200 away from the door sealing plate 100 is provided with a downwardly bent rain shield 210. The rain shield 200 is tilted to guide rainwater to flow down the rain shield 200, avoiding rainwater accumulation and rusting the rain shield 200, and effectively improving the structural rationality of the rain shield 200.

[0048] Reference Figure 1 and Figure 3It can be understood that the end of the inclined rain shield 200 away from the door plate 100 is provided with a rain shield 210 that is vertically bent downward. By providing the rain shield 210, the rain shield 210 is parallel to the door plate 100, and the overlapping area of ​​the vertical plane projection of the rain shield 200 and the vertical plane projection of the door plate 100 can be increased, reducing the probability of oblique rainwater entering the interior of the box transformer, and further enhancing the rainproof effect of the box transformer.

[0049] Reference Figure 4 and Figure 5 The transformer outer box of an embodiment of the utility model comprises the transformer door sealing device of the above embodiment and the door panel component 400, and the door panel component 400 is composed of a door panel body 410, a crossbeam 420 and two door posts 430. The first connecting parts 111 on both sides of the door sealing plate 100 are respectively bolted to the two door posts 430 through the first through hole 1101, the second connecting part 121 on the upper rear side of the door sealing plate 100 is riveted to the crossbeam 420 through the second through hole 1201, and the third connecting part 122 on the lower rear side of the door sealing plate 100 is bolted to the door panel body 410 through the third through hole 1202. In addition, the plate on the front side of the crossbeam 420 is bolted to the door post 430, and the plate on the front side of the crossbeam 420 cooperates with the first connecting part 111 to fix the door post 430 from both sides of the door post 430, thereby effectively improving the structural tightness of the transformer outer box.

[0050] Since the outer box of the box-type transformer adopts all the technical solutions of the box-type transformer door sealing device of the above-mentioned embodiment, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiment, which will not be repeated here.

[0051] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
