Description

Technical Field

[0001] This utility model relates to the field of transformer technology, and in particular to a waterproof structure for a transformer substation. Background Technology

[0002] A transformer is a device that uses electromagnetic induction to transform voltage, current, and impedance. It is a fundamental piece of equipment for power transmission and distribution and is widely used in industry, agriculture, transportation, and urban communities. Currently, the poor heat dissipation of the top of the transformer box can affect its normal operation. If ventilation holes are directly opened on the top of the box, there is a risk of water ingress when used in rainy seasons or rainy areas. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a waterproof structure for transformer substations to solve the heat dissipation and waterproofing problems of transformer cabinets.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A waterproof structure for a transformer substation includes a roof, which includes a base frame and multiple drainage units. Each drainage unit includes a bottom drainage trough, a baffle, and a guide plate assembly. The bottom drainage trough is fixed to the base frame. The guide plate assembly is fixed in position and its bottom extends into the bottom drainage trough. An arched frame is fixed to the top of the guide plate assembly, and the baffle is fixed to the arched frame. A top drainage trough is fixedly connected between two adjacent guide plate assemblies of adjacent drainage units. Sealing caps are fixed to both ends of the multiple drainage units.

[0006] Furthermore, the guide plate assembly includes an inner guide plate and a top guide plate. There are two inner guide plates that are mirror-symmetrical, and the bottom of the inner guide plate extends into the top of the bottom drainage channel. There are two top guide plates that are mirror-symmetrical, and the bottom of the top guide plate extends between the two inner guide plates. The top drainage channel is fixedly connected between two adjacent top guide plates of adjacent drainage units.

[0007] Furthermore, the top of the box includes a fixing frame and a connector. The fixing frame is fixedly disposed between adjacent bottom drainage channels and directly below the top drainage channel. The connector is also disposed through all the drainage units. The connector has a fixing hole for the internal guide plate to pass through. The connector is located below the top guide plate.

[0008] Furthermore, guide plates are provided on both sides of the baffle, the guide plates are inclined downwards, and the bottom of the guide plates is located directly above the top drainage channel; a downwardly inclined blocking plate is fixed to the top of the bottom drainage channel.

[0009] Furthermore, the internal guide plate includes a first guide section, a second guide section, and a third guide section. The first guide section extends into the top of the bottom drainage groove. The second guide section is connected above the first guide section and has an inclination angle greater than that of the first guide section. The third guide section is connected above the second guide section and has an inclination angle less than that of the second guide section.

[0010] Furthermore, the top guide plate includes a fourth guide section and a fixing section. A fixing plate is fixed on the fixing section, and the arched frame is fixed on the fixing plate. The fourth guide section is inclined downward and connected to one side of the fixing section. The bottom of the fourth guide section extends between the two inner guide plates.

[0011] Furthermore, the top drainage channel includes a drainage plate and inclined plates connected to both sides of the drainage plate. The inclined plates are connected to the top guide plate, and the top drainage channel and the two top guide plates on both sides are an integral structure.

[0012] Furthermore, for the two outermost drainage units, the outer wall of the bottom drainage trough extends upward, one bottom of the arched frame is fixed to the outer wall of the bottom drainage trough, and the guide plate assembly includes an inner guide plate, a top guide plate, and an edge guide plate. The inner guide plate is close to the inner wall of the bottom drainage trough, and its bottom extends into the bottom drainage trough. The bottom of the top guide plate extends into the outer side of the inner guide plate, and the edge guide plate is disposed on the outer side of the top guide plate and has a gap between it and the outer wall of the bottom drainage trough.

[0013] Furthermore, the top of the edge guide plate is inclined and the inclination direction is consistent with the inclination direction of the top guide plate. The guide plate assembly also includes a longitudinal guide plate, which is disposed on the outside of the edge guide plate. A gap is also provided between the longitudinal guide plate and the outer wall of the bottom drainage groove.

[0014] Furthermore, the top of the tank also includes an extension frame and a sliding frame. The extension frame is located outside the drainage unit and fixed to the base frame, while the sliding frame is located above the extension frame and can slide outward along the extension frame.

[0015] The beneficial effects of this utility model are:

[0016] This invention discharges most of the rainwater that falls on the drainage unit through the top drainage channel, and discharges a small amount of rainwater that enters the gap between the baffle and the bottom drainage channel through the guide plate assembly and the bottom drainage channel. The guide plate assembly does not contact the baffle and the bottom drainage channel. This non-contact structure forms a heat dissipation channel in the waterproof unit, achieving both ventilation and heat dissipation while also achieving a waterproof effect.

[0025] To make the technical problems solved, the technical solutions and the beneficial effects of the utility model clearer, the utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] Example 1

[0027] like Figures 1-4 As shown, this embodiment provides a waterproof structure for a transformer substation, including a top 10.

[0028] The top of the tank 10 includes a base frame 11 and multiple drainage units 12. Each drainage unit 12 includes a bottom drainage channel 121, a baffle 122, and a guide plate assembly 123. The bottom drainage channel 121 is fixed to the base frame 11. The guide plate assembly 123 is fixed in position and its bottom extends into the bottom drainage channel 121. An arched frame 124 is fixed to the top of the guide plate assembly 123, and the baffle 122 is fixed to the arched frame 124. A top drainage channel 125 is fixedly connected between two adjacent guide plate assemblies 123 of adjacent drainage units 12. Sealing caps 126 are fixed to both ends of the multiple drainage units 12. When the sealing caps 126 are installed at both ends of the sealing drainage unit 12, they avoid the top drainage channel 125 and the bottom drainage channel 121.

[0029] Rainwater falls on the top of the transformer tank 10. Rainwater falling into the top drainage trough 125 can be directly discharged from the top of the tank 10. Most of the rainwater falling on the baffle 122 also flows into the top drainage trough 125 and is discharged there. When the rainfall is heavy, a small amount of rainwater enters the gap between the baffle 122 and the guide plate assembly 123. This rainwater flows into the bottom drainage trough 121 under the guidance of the guide plate assembly 123 and is discharged there. The transformer can dissipate heat through the gap between adjacent bottom drainage troughs 121, ensuring both heat dissipation and waterproofing.

[0030] Furthermore, the deflector assembly 123 includes an inner deflector 1231 and a top deflector 1232. There are two inner deflectors 1231 that are mirror-symmetrical, and the bottom of the inner deflector 1231 extends into the top of the bottom drain trough 121. There are two top deflectors 1232 that are mirror-symmetrical, and the bottom of the top deflector 1232 extends between the two inner deflectors 1231. The top drain trough 125 is fixedly connected between two adjacent top deflectors 1232 of adjacent drain units 12.

[0031] Rainwater enters the gap between the baffle 122 and the top guide plate 1232, and after being guided twice by the inner guide plate 1231 and the top guide plate 1232, it finally flows into the bottom drainage channel 121 and flows out from the bottom drainage channel 121. Moreover, the top guide plate 1232 does not contact the baffle 122 and the inner guide plate 1231, and the inner guide plate 1231 does not contact the bottom drainage channel 121. This non-contact structure forms a heat dissipation channel. The two-stage guidance can enhance the breathability and heat dissipation effect while ensuring the waterproof effect.

[0032] Furthermore, the top of the box 10 includes a fixing frame 127 and a connector 128. The fixing frame 127 is fixedly disposed between adjacent bottom drainage channels 121 and is located directly below the top drainage channel 125. The connector 128 is also disposed through all drainage units 12. The connector 128 has a fixing hole 129 for the internal guide plate 1231 to pass through. The connector 128 is located below the top guide plate 1232.

[0033] The mounting bracket 127 is hollow inside, allowing simultaneous connection between two adjacent bottom drainage channels 121, thus achieving interconnection between the bottom drainage channels 121 and enhancing drainage performance. Preferably, all bottom drainage channels 121 and the mounting bracket 127 are integrally formed. The internal guide plate 1231 is fixed to the connector 128 through the fixing hole 129, facilitating the installation of the internal guide plate 1231. The connector 128 can independently support the internal guide plate 1231, ensuring that the internal guide plate 1231 does not contact the bottom drainage channel 121 or the top guide plate 1232.

[0034] Furthermore, guide plates 1210 are provided on both sides of the baffle 122. The guide plates 1210 are inclined downwards, and the bottom of the guide plates 1210 is located directly above the top drainage channel 125. A downwardly inclined baffle plate 1211 is fixed to the top of the bottom drainage channel 121. The guide plates 1210 can preferentially guide rainwater on the baffle 122 into the top drainage channel 125. The baffle plate 1211 is fixed to the sealing cover 126, which can prevent rainwater in the bottom drainage channel 121 from splashing upwards when flowing out of the bottom drainage channel 121, and can also prevent rainwater from directly entering the bottom drainage channel 121.

[0035] Furthermore, the internal guide plate 1231 includes a first guide portion 12311, a second guide portion 12312, and a third guide portion 12313. The first guide portion 12311 extends into the top of the bottom drainage channel 121. The second guide portion 12312 is connected above the first guide portion 12311 and has an inclination angle greater than that of the first guide portion 12311. The third guide portion 12313 is connected above the second guide portion 12312 and has an inclination angle less than that of the second guide portion 12312. Through this configuration, the fixation between the internal guide plate 1231 and the connector 128 is more stable, achieving precise flow guidance through the mutual cooperation between the internal guide plate 1231, the top guide plate 1232, and the bottom drainage channel 121.

[0036] Furthermore, the top guide plate 1232 includes a fourth guide portion 12321 and a fixing portion 12322. A fixing plate 1212 is fixed on the fixing portion 12322, and the arched frame 124 is fixed on the fixing plate 1212. The fourth guide portion 12321 is inclined downward and connected to one side of the fixing portion 12322. The bottom of the fourth guide portion 12321 extends between the two inner guide plates 1231.

[0037] Furthermore, the top drainage channel 125 includes a drainage plate 1251 and inclined plates 1252 connected to both sides of the drainage plate 1251. The inclined plates 1252 are connected to the top guide plates 1232, and the top drainage channel 125 and the two top guide plates 1232 on both sides are an integral structure. With the above structure, rainwater on the baffle 122 is more easily guided to the top drainage channel 125.

[0038] Furthermore, for the two outermost drainage units 12, the outer wall of the bottom drainage trough 121 extends upward, and one bottom of the arched frame 124 is fixed to the outer wall of the bottom drainage trough 121. The guide plate assembly 123 includes an inner guide plate 1231, a top guide plate 1232, and an edge guide plate 1233. The inner guide plate 1231 is close to the inner wall of the bottom drainage trough 121, and its bottom extends into the bottom drainage trough 121. The bottom of the top guide plate 1232 extends into the outer side of the inner guide plate 1231. The edge guide plate 1233 is located on the outer side of the top guide plate 1232 and has a gap between it and the outer wall of the bottom drainage trough 121.

[0039] Furthermore, the top of the edge guide plate 1233 is inclined in the same direction as the top guide plate 1232. The guide plate assembly 123 also includes a longitudinal guide plate 1234, which is preferably a straight plate. The longitudinal guide plate 1234 is located on the outside of the edge guide plate 1233, and a gap is also provided between the longitudinal guide plate 1234 and the outer wall of the bottom drainage channel 121. The longitudinal guide plate 1234 assists the edge guide plate 1233, which can better guide the rainwater at the edge, allowing the rainwater to flow accurately into the bottom drainage channel 121.

[0040] Example 2

[0041] like Figures 1-7 As shown, this embodiment provides a waterproof structure for a transformer substation. Based on embodiment 1, the top of the substation 10 also includes an extension frame 13 and a sliding frame 14. The extension frame 13 is located outside the drainage unit 12 and fixed on the base frame 11. The sliding frame 14 is located above the extension frame 13 and can slide outward along the extension frame 13.

[0042] The sliding frame 14 is mounted on the extension frame 13 via a slide rail. The extension frame 13 and the drainage unit 12 are sealed and fixedly connected. The heat dissipation function of the transformer can be achieved through multiple drainage units 12. The entire area of ​​the top of the tank 10 does not need to be set up as drainage units 12.

[0043] This invention discharges most of the rainwater falling on the drainage unit 12 through the top drainage channel 125, and discharges a small amount of rainwater that enters the gap between the baffle 122 and the drainage channel 121 through the guide plate assembly 123 and the bottom drainage channel 121. The guide plate assembly 123 does not contact the baffle 122 and the bottom drainage channel 121. This non-contact structure forms a heat dissipation channel in the waterproof unit, achieving both ventilation and heat dissipation functions and waterproof effect.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model shall fall within the protection scope of the present utility model.
