Description

Technical Field

[0001] This invention relates to the field of transformer technology, specifically to a complete set of equipment for a 10kV pole-mounted transformer platform with natural heat dissipation and energy-saving structure. Background Technology

[0002] A pole-mounted transformer is a common type of electrical equipment, usually installed on a utility pole. It converts high-voltage electrical energy into low-voltage electrical energy suitable for users, supplying power to the surrounding area. It has a compact structure, including a transformer box, a distribution box, and other parts, and is also equipped with protective devices such as arresters. It can operate stably in outdoor environments and plays an important role in voltage conversion and power distribution in the power distribution network.

[0003] In the Chinese patent with publication number CN220651768U, entitled "A novel 10kV pole-mounted transformer platform complete set of equipment", the output end of the dual-axis servo motor drives the take-up reel to rotate through the rotating shaft, and at the same time can wind up the traction rope, thereby enabling the distribution cabinet and transformer to move upward, thus performing the installation work of the distribution cabinet and transformer without the need for lifting equipment to transport the distribution cabinet and transformer upward. This patent cannot effectively improve the heat dissipation performance of transformers. In contrast, existing transformer sets often use electric cooling fans to increase the heat dissipation performance of transformers, which cannot effectively utilize natural wind. As a result, the heat dissipation effect of transformers is poor. Moreover, the continuous operation of electric cooling fans consumes a lot of electricity, resulting in poor energy efficiency. Furthermore, the assembly flexibility of transformer sets is poor, making daily maintenance inconvenient. Summary of the Invention

[0010] According to the above technical solution, a drainage perforated plate is placed on the top of the inner side of the water storage tank, and filter cotton is placed on the top of the drainage perforated plate.

[0011] According to the above technical solution, a modular hoisting assembly is provided at the bottom of the trough-shaped frame, and the modular hoisting assembly includes a power distribution box; A distribution box is installed at the bottom of the trough-shaped frame, and I-shaped hangers are fixed on both sides of the top of the distribution box; The slotted frame has clamping frames welded to both ends on one side, and a T-shaped frame is clamped between the two opposing clamping frames. The top two ends of the T-shaped frame are embedded inside the clamping frames. A lifting screw is rotatably installed between the two T-shaped frames.

[0014] According to the above technical solution, one end of the hoisting screw is connected to a driven gear, and two assembly hoops are fixed on the outside of the utility pole at the bottom of the slotted frame. A drive rod is rotatably installed on one side of the two assembly hoops, and a drive gear is connected to the top of the drive rod. The driven gear meshes with the drive gear.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. Equipped with a natural heat dissipation component, the water control valve is intelligently controlled by a controller to ensure a fixed amount of water inside the heat dissipation box. The corrugated ceramic plates and water-absorbing ceramic plates are made of porous ceramic material. After the water-absorbing ceramic plates absorb the water inside the heat dissipation box, the water permeates the entire corrugated ceramic plate from the bottom under capillary action. When the natural wind drives the fan and cross-flow fan to rotate, the rotation of the cross-flow fan increases the air flow speed inside the heat dissipation box. The fast-flowing air accelerates the evaporation of water absorbed by the corrugated ceramic plates. The staggered distribution of the corrugated ceramic plates increases the contact area between the flowing air and the corrugated ceramic plates, allowing the water absorbed by the corrugated ceramic plates to evaporate quickly. The evaporation of water absorbs heat, and through heat conduction, it cools the transformer. The equipment has an energy-saving structure with natural heat dissipation. While the heat dissipation box, heat dissipation fins and heat dissipation plates increase the heat dissipation area of ​​the transformer, the rapid flow of natural wind and the promotion of water evaporation by natural wind achieve rapid cooling of the transformer. There is no need to install additional cooling fans to cool the transformer, which is energy-saving and environmentally friendly. The heat sink has a side air inlet and an air inlet shroud on one side. The multi-directional design of the air inlet shroud allows natural air from different directions to enter the heat sink from the shroud. After the natural air enters the air inlet shroud, it creates a canyon effect, which speeds up the airflow and makes the water absorbed by the wave ceramic pieces near the side air inlet evaporate faster, further improving the heat dissipation effect. When it rains, rainwater passes through the conical mesh cover and is absorbed by the filter cotton. After the conical mesh cover and filter cotton filter the rainwater, it flows into the water storage tank through the holes in the drain plate. The equipment can store rainwater, reducing the frequency of manual water replenishment, and the equipment is more green and environmentally friendly. The bellows and isolation net are assembled with the heat dissipation box via assembly slots. The corrugated ceramic plates are slidably connected to the installation rails via T-blocks. The installation of the corrugated ceramic plates, bellows, and isolation net does not require the use of fixing bolts, making the structural installation and maintenance convenient and quick.

[0016] 2. Equipped with modular hoisting components, the distribution box is installed using a flexible hoisting method. During installation of the channel frame, the T-block is placed between two opposing clamping frames, and the guide opening is aligned with the guide rail. The clamping frames and guide rail can respectively clamp the T-frame and the limiting rod. When the two channel frames move away from each other, the T-frame and the limiting rod can quickly separate from the channel frame. The T-frame and the limiting rod are installed in a splicing manner, making installation convenient and quick. When the distribution box needs to be inspected, the drive rod is manually rotated. Under the driving connection of the drive gear and the driven gear, the drive rod drives the hoisting screw to rotate, so that the two limit rods move closer to each other along the guide rail. When the two limit rods move closer to each other, the hoisting rod drives the distribution box to descend, reducing the height of the distribution box and making it easier for maintenance personnel to carry out maintenance. The distribution box is slidably connected to the hoisting rail via an I-shaped lifting rod. When the distribution box needs to be disassembled as a whole, the baffle is removed from inside the hoisting rail, a pushing force is applied to the distribution box, and the distribution box can be removed. The installation and disassembly of the distribution box is convenient and quick.

[0017] In summary, in the natural heat dissipation assembly, the corrugated ceramic plates are installed inside the heat dissipation box via a sliding connection between the T-shaped blocks and the mounting rails. The air box and the isolation net are assembled with the heat dissipation box via assembly slots. In the modular hoisting assembly, the T-shaped frame and the limiting rod are fixed by a movable snap-fit ​​method, and the distribution box is fixed by a sliding connection method. Most structures in both assemblies can be flexibly disassembled and installed, which improves the installation and maintenance convenience of the complete set of pole-mounted transformer equipment.

[0020] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0021] Example: Figure 1-12 As shown, this invention provides a complete set of equipment for a 10kV pole-mounted transformer platform with natural heat dissipation and energy-saving structure. It includes two poles (1), with a natural heat dissipation assembly (2) located between each pole. The natural heat dissipation assembly (2) includes a channel frame (201), a transformer (202), a heat dissipation box (203), a mounting rail (204), corrugated ceramic plates (205), a T-block (206), water-absorbing ceramic plates (207), a liquid level sensor (208), a sealing plate (209), a fixing pin (210), and fixing holes (211). 212, 213, 214, 215, 216, 217, 218, 219, 220, 221, 222, 223, 224, 225, 226, 227, 228, 229, 230, 230, 231, 24, 225, 226, 227, 228, 229, 230, 231, 232, 232, 233, 234; 24, 25, 26, 227, 228, 229, 230, 231, 232, 233, 234; 24, 25, 26, 237, 228, 239, 230, 231, 232, 233, 234; A channel-shaped frame 201 is fixed in the middle of the utility pole 1. There are two channel-shaped frames 201. A transformer 202 is installed in the middle of the top of the channel-shaped frame 201. Heat dissipation boxes 203 are installed on both sides of the transformer 202. Multiple corrugated ceramic plates 205 are installed inside the heat dissipation boxes 203. Water-absorbing ceramic plates 207 are connected to the bottom of the corrugated ceramic plates 205. The corrugated ceramic plates 205 and the water-absorbing ceramic plates 207 are made of porous ceramic material and have good water absorption capacity. When air flows inside the heat dissipation box 203, there are gaps between the corrugated ceramic plates 205, and the contact area between the flowing air and the corrugated ceramic plates 205 is larger. When the flowing air blows the water-absorbing corrugated ceramic plates 205, the absorbed water can evaporate quickly. Multiple mounting rails 204 are welded at equal intervals on both sides of the heat sink 203. Multiple T-blocks 206 are equally spaced on one side of the corrugated ceramic sheet 205. The T-blocks 206 slide into the adjacent mounting rails 204. The corrugated ceramic sheet 205 is slidably connected to the mounting rails 204 through the T-blocks 206, which facilitates the installation and removal of the corrugated ceramic sheet 205. An isolation net 220 is slidably installed on the other side of the heat sink 203 through the assembly groove 216. The isolation net 220 plays an isolation role to prevent external debris from entering the heat sink 203. Sealing plates 209 are installed at the bottom of both sides of the heat sink 203. The two sealing plates 209 are located at the bottom of the air box 217 and the isolation net 220, respectively. The sealing plates 209 play a role in sealing and storing water. When water is injected into the heat sink 203, the injected water can be stored at the bottom of the inner side of the heat sink 203. The heat sink 203 has two equally spaced fixing ears 212 welded on one side. A positioning rod 213 is slidably connected inside the fixing ears 212. A circular plate 214 is welded to one end of the positioning rod 213. A fixing spring 215 is connected between the circular plate 214 and the fixing ears 212. Fixing pins 210 are movably inserted into the two sides of the heat sink 203 at the positions corresponding to the positioning rods 213. A fixing hole 211 is opened at one end of the fixing pin 210. The top end of the positioning rod 213 is embedded in the adjacent fixing hole 211. The heat sink 203 has mounting slots 216 on both sides. A fan box 217 is slidably mounted on one side of the heat sink 203 via the mounting slots 216. A cross-flow fan 218 is rotatably mounted inside the fan box 217. A fan-driven fan 219 is connected to the top end of the rotating shaft of the cross-flow fan 218. Natural wind can drive the fan-driven fan 219 to rotate, which in turn drives the cross-flow fan 218 to rotate. The rotation of the cross-flow fan 218 increases the airflow speed inside the heat sink 203. The heat sink 203 is located on one side at the top of the water inlet 223, etc. Multiple side air inlets 221 are provided at intervals. An air inlet hood 222 is connected to the outside of the side air inlet 221. The openings of two adjacent air inlets 222 face opposite directions. The multi-directional design of the air inlet hood 222 allows natural wind from different directions to enter the heat dissipation box 203 from the air inlet hood 222. After the natural wind enters the air inlet hood 222, it forms a canyon effect, which speeds up the air flow and further speeds up the air flow at the side air inlet hood 221. The water absorbed by the wave ceramic plate 205 near the side air inlet hood 221 evaporates faster. A water inlet 223 is connected to the bottom of one side of the heat sink 203. A fixing hoop 224 is fixed to the outside of the utility pole 1. Support rings 225 are welded to both sides of the fixing hoop 224. A water storage tank 226 is fixed to the top of the support rings 225. A conical mesh cover 229 is installed on the top of the water storage tank 226. The conical mesh cover 229 can prevent leaves and other debris from entering the water storage tank 226. When debris falls to the top of the conical mesh cover 229, the conical design of the conical mesh cover 229 can prevent debris from being trapped. At the top of the water storage tank 226, a water supply pipe 230 is connected to one side of the top. The water supply pipe 230 is used to supply water into the water storage tank 226. A drainage perforated plate 227 is placed on the top of the inner side of the water storage tank 226. A filter cotton 228 is placed on the top of the drainage perforated plate 227. When it rains, rainwater passes through the conical mesh cover 229 and is absorbed by the filter cotton 228. After the conical mesh cover 229 and the filter cotton 228 filter the rainwater, it flows into the water storage tank 226 through the holes on the drainage perforated plate 227. A liquid level sensor 208 is installed on the bottom inner side of the heat sink 203. The bottom of the water storage tank 226 is connected to one end of the water control valve 231. The water inlet 223 is connected to one end of the three-way pipe 232. The other two ends of the three-way pipe 232 are respectively connected to the other end of the adjacent water control valve 231. The water control valve 231 is an electrically controlled valve. The output end of the liquid level sensor 208 is electrically connected to the input end of the controller. The input end of the water control valve 231 is electrically connected to the output end of the controller. The liquid level sensor 208 can detect whether there is still water inside the heat sink 203. When the heat sink 203 is short of water, the controller will open the water control valve 231, and the water inside the water storage tank 226 will flow through the three-way pipe 232 to deliver a certain amount of water into the heat sink 203. A heat sink 203 has a heat sink 234 connected to one side by multiple heat sink fins 233, and the heat sink 234 is in contact with one side of the transformer 202. The bottom of the channel frame 201 is provided with a modular hoisting assembly 3, which includes a distribution box 301, an I-shaped hoisting rod 302, a clamping frame 303, a T-shaped frame 304, a hoisting screw 305, a hoisting seat 306, a limiting rod 307, a guide port 308, a guide slide rail 309, a hoisting rotating rod 310, a hoisting channel rail 311, a baffle 312, a magnetic suction plate 313, a driven gear 314, an assembly hoop 315, a drive rod 316, and a drive gear 317. A distribution box 301 is installed at the bottom of the trough-shaped frame 201, and I-shaped hangers 302 are fixed on both sides of the top of the distribution box 301. A clamping frame 303 is welded to both ends of one side of the channel frame 201. A T-shaped frame 304 is clamped between the two opposing clamping frames 303. The top ends of the T-shaped frame 304 are embedded inside the clamping frames 303. A lifting screw 305 is rotatably installed between the two T-shaped frames 304. The outer ends of the lifting screw 305 are connected to a lifting seat 306 through screw holes. A limit rod 307 is welded to the top of the lifting seat 306. Guide openings 308 are provided at both ends of the limit rod 307. A guide rail 309 is welded to one side of the channel frame 201 between the two clamping frames 303. The guide openings 308 are slidably sleeved on the guide rail 309. On the outside, the guide rail 309 has a smooth surface, and the lifting screw 305 is a bidirectional screw. When the lifting screw 305 rotates, the two limiting rods 307 can move closer or further away from each other along the guide rail 309. When the two slotted frames 201 are fastened to the outside of the utility pole 1, the clamping frame 303 and the guide rail 309 can clamp the T-shaped frame 304 and the limiting rod 307 respectively. When the two slotted frames 201 move away from each other, the T-shaped frame 304 and the limiting rod 307 can quickly separate from the slotted frame 201. The T-shaped frame 304 and the limiting rod 307 are installed in a splicing manner, which is convenient and quick to install. The bottom of the lifting base 306 is rotatably connected to one end of the lifting boom 310, and the other end of the lifting boom 310 is rotatably connected to the lifting rail 311. The I-shaped lifting rod 302 is slidably embedded in the interior of the adjacent lifting rail 311, and the outer side of the I-shaped lifting rod 302 is in contact with the inner side of the adjacent lifting rail 311. A baffle 312 is inserted into one end of the lifting rail 311, and a magnetic plate 313 is connected to the top of the baffle 312. The bottom surface of the magnetic plate 313 is in contact with the top surface of the lifting rail 311. The magnetic plate 313 is a neodymium iron boron magnet, and the lifting rail 311 is made of iron. Under the magnetic attraction, the baffle 312 can be stably fixed and prevent the I-shaped lifting rod 302 from moving out of the interior of the lifting rail 311. One end of the lifting screw 305 is connected to a driven gear 314. Two mounting hoops 315 are fixed on the outside of the utility pole 1 at the bottom of the slotted frame 201. A drive rod 316 is rotatably mounted on one side of the two mounting hoops 315. A drive gear 317 is connected to the top of the drive rod 316. The driven gear 314 meshes with the drive gear 317. Under the action of the gear connection, rotating the drive rod 316 can drive the lifting screw 305 to rotate.

[0022] The working principle and usage process of this invention are as follows: In use, the water supply pipe 230 is connected to the outlet of the water pump. Water is supplied to the water storage tank 226 through the water supply pipe 230. The controller controls the water control valve 231, and the water inside the water storage tank 226 flows through the three-way pipe 232 and the inlet head 223 to be meteredly supplied to the heat dissipation box 203. The supplied water is stored at the bottom inside the heat dissipation box 203, and the water level inside the heat dissipation box 203 does not exceed the top of the sealing plate 209, the corrugated ceramic plate 205, and... The water-absorbing ceramic plate 207 is made of porous ceramic material and has good water absorption capacity. The water-absorbing ceramic plate 207 absorbs water inside the heat sink 203. Under capillary action, water soaks the entire wave-shaped ceramic plate 205 from the bottom. When the natural wind drives the fan 219 to rotate, it also drives the cross-flow fan 218 to rotate. The rotation of the cross-flow fan 218 increases the airflow speed inside the heat sink 203. The rapidly flowing air accelerates the evaporation of water absorbed by the wave-shaped ceramic plate 205. The water-absorbing ceramic plate 205... The staggered distribution of the corrugated ceramic plates 205, with gaps between each pair, allows for a larger contact area between the flowing air and the ceramic plates 205. Water absorbed by the ceramic plates 205 evaporates quickly, absorbing heat. This rapid airflow, combined with the heat absorption from evaporation, rapidly cools the heat dissipation box 203. A heat dissipation plate 234 on one side of the heat dissipation box 203 contacts the outside of the transformer 202. The heat dissipation box 203, heat dissipation fins 233, and heat dissipation plate 234 are made of copper-aluminum alloy, possessing excellent thermal conductivity. Through heat conduction, they effectively cool the transformer 202. The equipment features an energy-saving structure for natural heat dissipation. While increasing the heat dissipation area of ​​the transformer 202, the rapid flow of natural wind and its promotion of water evaporation further accelerate the cooling process. No additional cooling fan is required, making it energy-efficient and environmentally friendly. The heat sink 203 has a side air inlet 221 and an air inlet shroud 222 on one side. The openings of two adjacent air inlets shrouds 222 face opposite directions. The multi-directional design of the air inlet shrouds 222 allows natural air from different directions to enter the heat sink 203 from the air inlet shrouds 222. After entering the air inlet shrouds 222, the natural air creates a canyon effect, which increases the airflow speed and further increases the airflow speed at the side air inlet 221. The water absorbed by the wave ceramic plate 205 near the side air inlet 221 evaporates faster. By further increasing the water evaporation speed, the heat dissipation effect is further improved. A drainage perforated plate 227 is placed on the top of the inner side of the water storage tank 226, and a filter cotton 228 is placed on top of the drainage perforated plate 227. When it rains, rainwater passes through the conical mesh cover 229 and is absorbed by the filter cotton 228. After the conical mesh cover 229 and the filter cotton 228 filter the rainwater, it flows into the water storage tank 226 through the holes on the drainage perforated plate 227. The equipment can store rainwater, reduce the frequency of manual water replenishment, and the equipment is more green and environmentally friendly. A liquid level sensor 208 is installed on the bottom inner side of the heat sink 203. When the heat sink 203 is short of water, the controller will open the water control valve 231, and the water storage tank 226 will then supply water into the heat sink 203. The bellows 217 and the isolation net 220 are assembled with the heat sink 203 via the assembly slot 216. The corrugated ceramic plate 205 is slidably connected to the mounting rail 204 via the T-block 206. During construction, the corrugated ceramic plate 205, bellows 217 and isolation net 220 are easy and quick to install. When the cross-flow fan 218 and isolation net 220 need cleaning and maintenance, the structure can be quickly disassembled manually. When the corrugated ceramic plate 205 needs cleaning and maintenance, the positioning rod 213 is pulled, the fixing spring 215 is compressed, the positioning rod 213 is moved out of the fixing hole 211, and the fixing pin 210 is moved out of the heat sink 203. After all the fixing pins 210 are removed, the corrugated ceramic plate 205 is pulled out of the heat sink 203. The installation of the corrugated ceramic plate 205, bellows 217 and isolation net 220 does not require fixing bolts, and the structure is easy and quick to install and maintain. The distribution box 301 is installed using a flexible hoisting method. During installation, the T-shaped block 206 is placed between two opposing clamping frames 303, and the guide port 308 is connected to the guide rail 309. The clamping frames 303 and the guide rail 309 can clamp the T-shaped frame 304 and the limiting rod 307 respectively. When the two slotted frames 201 move away from each other, the T-shaped frame 304 and the limiting rod 307 can quickly separate from the slotted frame 201. The T-shaped frame 304 and the limiting rod 307 are installed in a splicing manner, which is convenient and quick to install. When the distribution box 301 needs to be inspected, the drive rod 316 is manually rotated. Under the driving connection of the drive gear 317 and the driven gear 314, the drive rod 316 drives the hoisting screw 305 to rotate, so that the two limit rods 307 move closer to each other along the guide rail 309. When the two limit rods 307 move closer to each other, the hoisting rotating rod 310 drives the distribution box 301 to descend. The connection line between the distribution box 301 and the transformer 202 is left with sufficient length to facilitate the smooth descent of the distribution box 301, reduce the height of the distribution box 301, and facilitate the maintenance personnel's inspection. The distribution box 301 is slidably connected to the hoisting rail 311 via the I-shaped lifting rod 302. When the distribution box 301 needs to be disassembled as a whole, the baffle 312 is removed from the inside of the hoisting rail 311, and a pushing force is applied to the distribution box 301 to remove it. The installation and disassembly of the distribution box 301 is convenient and quick. In the natural heat dissipation component 2, the wave-shaped ceramic plate 205 is installed inside the heat dissipation box 203 through the sliding connection of the T-shaped block 206 and the mounting slide rail 204. The air box 217 and the isolation net 220 are assembled with the heat dissipation box 203 through the assembly slot 216. In the modular hoisting component 3, the T-shaped frame 304 and the limit rod 307 are fixed by a movable snap-fit, and the power distribution box 301 is fixed by a sliding connection. Most of the structures in the two components can be flexibly disassembled and installed, which improves the installation and maintenance convenience of the equipment as a whole.
