Description

Technical Field

[0001] The utility model relates to the technical field of transformer box frame splicing pieces, in particular to a transformer box frame splicing piece with good heat dissipation performance. Background Art

[0002] Transformer box frame splicing parts are a kind of parts used to splice multiple pieces into a box frame. For example, a box-type transformer is made of box frame panels, door panels and other parts spliced ​​and fixed. In order to ensure the heat dissipation efficiency of the entire box frame, several heat dissipation holes will be opened on both sides of the box frame panels to transfer the heat in the transformer oil to the air in time, thereby ensuring the normal operation of the transformer.

[0003] When using, traditional transformers are generally installed on the ground, and then cables are used to connect the various devices on the inner wall of the transformer to the outside world, thereby ensuring the stable transmission and operation of electricity through the action of the transformer. However, in actual use, it is found that the ground where some transformers are installed is relatively humid and contains a lot of impurities. Under long-term use, the box frame will be corroded and penetrated, causing damage to internal components and even leading to safety accidents. Damage will be caused by setting pads at the four corners of the box frame, but long-term use will cause the pads to sink, which will also affect the normal use of the transformer. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the ground at the installation location of some transformers in the prior art is relatively moist and has a lot of impurities. Under long-term use, the box frame plate will be corroded and penetrated, causing damage to internal components and even leading to safety accidents. The damage will be caused by setting pads at the four corners of the box frame plate, but long-term use will cause the pads to be concave, which will also affect the normal use of the transformer. A transformer box frame splicing part with good heat dissipation performance is proposed.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a transformer box frame splicing piece with good heat dissipation performance, comprising a box frame plate, a top plate is fixedly connected to the surface of one side of the box frame plate, a door plate is hinged on the side of the inner wall of the box frame plate close to each other, a number of evenly distributed heat dissipation holes are respectively opened on both sides of the surface of the box frame plate, an adjustment device is arranged on the surface of the box frame plate, the adjustment device comprises two mounting plates, the two mounting plates are respectively fixedly connected to the two sides of the surface of the box frame plate, screws are respectively threadedly connected to the two side surfaces of the two mounting plates, a bottom plate is rotatably connected to the circular arc surface of the screw, and a cone block is fixedly connected to one end of the screw.

[0006] The effect achieved by the above components is that when the box frame of the transformer is in use, it has a better distance from the ground, so it is not easily corroded and damaged by impurities and sewage on the ground, ensuring the normal use of the box frame, and making the components of the transformer less likely to be damaged, extending its service life and reducing the occurrence of safety accidents.

[0011] Preferably, a surface of one side of the bottom plate away from the mounting plate is fixedly connected with a plurality of evenly distributed reinforcement protrusions, and the cross-sections of the plurality of reinforcement protrusions are all conical.

[0012] The effect achieved by the above components is that, through the setting of the protrusions, the bottom plate can be firmly contacted and pressed on the ground, and it is not easy to shift the position, thereby improving the stability of the entire transformer.

[0013] Preferably, a nut is threadedly connected on the arc surface of the screw, and the nut is located on the arc surface of the screw between the mounting plate and the base plate.

[0014] The effect achieved by the above components is: through the setting of the nut, when the screw is rotated, after the height position of the box frame plate is adjusted, the nut is contacted and squeezed with the mounting plate, so that the screw is not easy to rotate and loosen.

[0015] Preferably, protective devices are respectively provided on both sides of the surface of the box frame plate, and the protective devices include a protective shell, and mounting blocks are respectively fixedly connected on both sides of the surface of the protective shell, and bolts are threadedly connected to the surface of the mounting block, and the bolts are threadedly connected to the surface of the box frame plate, and the protective shell cover is arranged on the surface of the heat dissipation hole.

[0016] The effect achieved by the above components is that when the transformer box is in use, the heat dissipation holes not only play a good heat dissipation function, but also make it difficult for impurities and rainwater to enter during use, thereby ensuring the normal operation and use of the transformer components on the inner wall of the box frame plate, and not prone to damage and accidents.

[0017] Preferably, an operating block is fixedly connected to one end surface of the bolt, and a plurality of anti-slip protrusions are provided on the surface of the operating block.

[0019] Preferably, a protective pad is fixedly connected to a surface of one side of the protective shell close to the box frame plate, and the protective pad is a rubber pad.

[0020] The effect achieved by the above components is: by adding the protective pad, the protective shell is more closely attached to the surface of the box frame plate, and it is not easy to produce gaps, so that the protective shell can better protect the heat dissipation holes and prevent rainwater and impurities from entering.

[0029] Reference Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment: the adjusting device 5 includes two mounting plates 51, and the two mounting plates 51 are fixedly connected to the two sides of the surface of the box frame plate 1 respectively. The two side surfaces of the two mounting plates 51 are respectively penetrated with screw rods 52, and the arc surface of the screw rods 52 is rotatably connected with a bottom plate 53, and one end of the screw rods 52 is fixedly connected with a cone block 54. When the horizontal height of the box frame plate 1 installed on the ground is adjusted, first, the cone blocks 54 on the screw rods 52 on both sides of the box frame plate 1 are inserted into the ground, and the bottom plate 53 on the screw rods 52 is contacted and pressed on the ground, and then the screw rods 52 are rotated to rotate the screw rods 52 on the surface of the mounting plates 51, so that the heights of the four corners of the box frame plate 1 are adjusted to different degrees until the box frame plate 1 maintains a horizontal position. At this time, when the box frame plate 1 of the transformer is in use, it is better to create a distance with the ground, so that it is not easy to be eroded and damaged by impurities and sewage on the ground, thereby ensuring the normal use of the box frame plate 1, and also making it difficult for the components of the transformer to be damaged, extending its service life, and reducing the occurrence of safety accidents.

[0030] Reference Figure 1 , Figure 2 and Figure 3As shown, in this embodiment: a limiting rod 56 is fixedly connected to the surface of the bottom plate 53, and limiting grooves 57 are respectively provided on the two side surfaces of the two mounting plates 51, and the limiting rod 56 is slidably connected to the inner wall of the limiting groove 57. Through the sliding setting of the limiting rod 56 and the limiting groove 57, the position of the bottom plate 53 is ensured to be stable when the screw 52 rotates, so as to better and more efficiently adjust the position height of the box frame plate 1 of the transformer, and a bearing 55 is fixedly connected to the arc surface of the screw 52, ​​the inner ring of the bearing 55 is fixedly connected to the screw 52, ​​and the outer ring of the bearing 55 is fixedly connected to the inner wall of the bottom plate 53. Through the setting of the bearing 55, the screw 52 is smoother when rotating, reducing the friction damage between the bottom plate 53, thereby ensuring the normal use of the adjustment device 5.

[0031] Reference Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment: a surface of the bottom plate 53 on one side away from the mounting plate 51 is fixedly connected with a plurality of uniformly distributed reinforcing protrusions 58, and the cross-sections of the plurality of reinforcing protrusions 58 are all conical. Through the arrangement of the protrusions, the bottom plate 53 can be firmly contacted and extruded on the ground, and it is not easy to shift the position, thereby improving the stability of the entire transformer. A nut 59 is threadedly connected to the arc surface of the screw rod 52, and the nut 59 is located at the arc surface position of the screw rod 52 between the mounting plate 51 and the bottom plate 53. Through the arrangement of the nut 59, when the screw rod 52 rotates and the height position of the box frame plate 1 is adjusted, the nut 59 is contacted and extruded with the mounting plate 51, so that the screw rod 52 is not easy to rotate and loosen.

[0032] Reference Figure 1 and Figure 4 As shown, in this embodiment: the protective device 6 includes a protective shell 61, and mounting blocks 62 are fixedly connected on both sides of the surface of the protective shell 61, and bolts 63 are threadedly connected to the surface of the mounting block 62. The bolts 63 are threadedly connected to the surface of the box frame plate 1, and the protective shell 61 is covered on the surface of the heat dissipation hole 4. When the heat dissipation hole 4 on the surface of the box frame plate 1 is protected, the protective shell 61 is first contacted and squeezed on the surface of the box frame plate 1, and the protective shell 61 is shielded on the surface of the heat dissipation hole 4, and then two bolts 63 are threadedly connected to the mounting blocks 62 on both sides of the surface of the protective shell 61, until the bolts 63 are stably connected to the surface of the box frame plate 1. At this time, when the transformer box is in use, the heat dissipation hole 4 not only plays a good heat dissipation function, but also makes it difficult for impurities and rainwater to enter during use, thereby ensuring the normal operation and use of the transformer components on the inner wall of the box frame plate 1, and not prone to damage and accidents.

[0033] Reference Figure 1 and Figure 4As shown, in the present embodiment: an operating block 64 is fixedly connected to the surface of one end of the bolt 63, and a plurality of anti-slip protrusions are provided on the surface of the operating block 64. Through the provision of the operating block 64, the bolt 63 can be more convenient to use, so that the protective shell 61 can be more conveniently installed on the surface of the box frame plate 1, thereby improving the convenience of using the protective device 6. A protective pad 65 is fixedly connected to the surface of the side of the protective shell 61 close to the box frame plate 1. The protective pad 65 is a rubber pad. Through the provision of the protective pad 65, the protective shell 61 is more closely attached to the surface of the box frame plate 1, and gaps are not easily generated, so that the protective shell 61 can better protect the heat dissipation holes 4 from entering rainwater and impurities.

[0034] Working principle: When adjusting the horizontal height of the box frame plate 1 installed on the ground, first, the cone blocks 54 on the screws 52 on both sides of the box frame plate 1 are inserted into the ground, and the bottom plates 53 on the screws 52 are contacted and pressed on the ground, and then the screws 52 are rotated to make the screws 52 rotate on the surface of the mounting plate 51, so that the heights of the four corners of the box frame plate 1 are adjusted to different degrees until the box frame plate 1 maintains a horizontal position, and then the nuts 59 are rotated to make the nuts 59 contact and press on the surface of the mounting plate 51. At this time, when the box frame plate 1 of the transformer is in use, it is better spaced from the ground, so that it is not easily eroded and damaged by impurities, sewage, etc. on the ground, which ensures the normal use of the box frame plate 1 and makes the components of the transformer less likely to be damaged, thereby extending its service life and reducing the occurrence of safety accidents.

[0035] When protecting the heat dissipation holes 4 on the surface of the box frame plate 1, first, the protective shell 61 is contacted and squeezed on the surface of the box frame plate 1, so that the protective pad 65 on the protective shell 61 is contacted and squeezed on the surface of the box frame plate 1, and the protective shell 61 is shielded on the surface of the heat dissipation holes 4, and then the operating block 64 fixedly connected on the bolt 63 is rotated, and the two bolts 63 are respectively threadedly connected to the mounting blocks 62 on both sides of the surface of the protective shell 61 until the bolts 63 are stably connected to the surface of the box frame plate 1. At this time, when the transformer box is in use, the heat dissipation holes 4 not only play a good heat dissipation function, but also make it difficult for impurities and rainwater to enter during use, thereby ensuring the normal operation and use of the transformer components on the inner wall of the box frame plate 1, and not prone to damage and accidents.
