Description

Technical Field

[0001] The present invention relates to the technical field of transformers, and in particular to a noise-reducing transformer. Background Art

[0002] A transformer is an important device for transmitting electric energy. It changes the voltage by stepping up or stepping down the voltage to meet the voltage requirements of different electrical equipment. Since the transformer generates low-frequency noise during operation, the low-frequency noise is likely to affect the residents in the community. In residential communities, box-type transformers are mostly used. Installing the transformer and switch equipment in the box can reduce the noise pollution generated by the operation of the transformer equipment.

[0003] The box-type transformers in residential communities are usually installed outdoors. The heat generated during the operation of the transformer is relatively high. When used in cities with relatively low average annual temperatures, the temperature difference between the inside and outside of the box-type transformer is relatively large. The hot air inside the box-type transformer cannot be dissipated in time and will generate water vapor. The water vapor liquefies into small water droplets and adheres to the electrical equipment inside the box-type transformer, which is likely to damage the electrical equipment. Usually, heat dissipation treatment is performed on the bottom of the box-type transformer. Since hot air moves upward, most of the heat accumulates at the top inside the box-type transformer. Therefore, the contact path between the cold air at the bottom of the box-type transformer and the hot air inside the box-type transformer is relatively long, resulting in poor heat dissipation effect. Summary of the Invention

[0004] By providing a noise-reducing transformer in the embodiments of the present application, the problem in the prior art that the heat mostly accumulates at the top inside the box-type transformer, so the contact path between the cold air at the bottom of the box-type transformer and the hot air inside the box-type transformer is relatively long, resulting in poor heat dissipation effect is solved.

Detailed implementation manners

[0054] To facilitate the understanding of the present invention, the present application will be described more comprehensively below with reference to the relevant drawings; the preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein; on the contrary, these embodiments are provided to make the disclosure of the present invention more thorough and comprehensive.

[0055] It should be noted that the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only embodiments.

[0056] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs; the terms used in the description of the present invention in this specification are only for the purpose of describing specific embodiments and are not intended to limit the present invention; the term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0057] As Figures 1 to 17 shown, the present application provides a noise-reducing transformer, which includes a box body 100 and a cabinet door 110. A sound insulation cotton 111 is fixed on the inner side of the box body 100 and on the cabinet door 110 near the inside of the box body 100. The sound insulation cotton 111 reduces noise by absorbing the low-frequency sound waves of the transformer, and can reduce the noise generated by the operation of the transformer. It also includes a heat dissipation component 200, and the heat dissipation component 200 is used for dissipating heat from the electrical equipment in the box body 100;

[0058] The heat dissipation component 200 includes a shielding plate 210, a heat dissipation part 220 and an intake part 230;

[0059] The baffle plate 210 is fixed to the top of the box body 100. Heat dissipation grooves 211 are formed in the baffle plate 210. The heat dissipation grooves 211 facilitate the dissipation of heat. An opening is formed at the bottom of the heat dissipation grooves 211. The opening communicates with the inside of the box body 100. A ventilation plate 2111 is fixed in the opening. Through holes are formed in the ventilation plate 2111. The ventilation plate 2111 is used for ventilating the inside of the box body 100 and can play a role in preventing insects and rodents at the same time;

[0060] The heat dissipation part 220 includes a heat dissipation fan 221 and a cleaning head 223;

[0061] The heat dissipation fan 221 is fixed in the heat dissipation groove 211. The heat dissipation fan 221 is located above the ventilation plate 2111. The heat dissipation fan 221 is driven by a motor to rotate. When the heat dissipation fan 221 rotates for heat dissipation, the cleaning head 223 can contact the ventilation plate 2111 to clean the dust blocked at the through holes of the ventilation plate 2111, ensuring the normal circulation of air in the box body 100;

[0062] The heat dissipation fan 221 includes four fan blades 222. A cleaning head 223 is fixed near the ventilation plate 2111 on each fan blade 222;

[0063] Each of the fan blades 222 is a plate body with a hollow interior. The cleaning head 223 is a cylinder with a hollow interior and openings at both ends. One end of the cleaning head 223 extends into the fan blade 222. The connection between the cleaning head 223 and the fan blade 222 is sealed and fixed. The cleaning head 223 communicates with the inside of the fan blade 222. A brush is fixed at the spare end of the cleaning head 223. The brush can extend into the through holes of the ventilation plate 2111 to facilitate the cleaning of the dust in the through holes;

[0064] The air intake part 230 is used for pumping air into the fan blades 222, which can accelerate the flow of hot air in the box body 100. As the heat dissipation fan 221 rotates, it can drive the air around the ventilation plate 2111 to make a turbulent flow, increasing the contact area between the hot air in the box body 100 and the external cold air.

[0065] It should be noted that by pumping air into the fan blades 222 through the air intake part 230, the cleaning head 223 can drive the air around the ventilation plate 2111 to make a turbulent flow, increasing the contact area between the hot air in the box body 100 and the external cold air.

[0066] Specifically, as Figure 3 Figure 17 shown, the air intake part 230 includes an air pipe 231 and a guide pipe 233;

[0067] The ventilation pipe 231 is a cross-shaped pipe body. The air inlet end of the ventilation pipe 231 is rotatably connected to the air guide pipe 233. The air guide pipe 233 coincides with the axis of the cooling fan 221, and the rotating connection between the ventilation pipe 231 and the air guide pipe 233 is sealed. Air is introduced into the air guide pipe 233 through an air pump.

[0068] The ventilation pipe 231 has four air outlet ends, and a branch pipe 232 is fixed on each air outlet end. The air outlet end of one branch pipe 232 extends into one fan blade 222, and the connection between each branch pipe 232 and the fan blade 222 is sealed and fixed.

[0069] It should be noted that when the fan blade 222 rotates, the ventilation pipe 231 and the branch pipes 232 move synchronously with the fan blade 222, and the position of the air guide pipe 233 remains unchanged, so it is not easy to entangle the pipes. Air is introduced into the air guide pipe 233 through an air pump, so that the gas enters the ventilation pipe 231, and then is split into four branch pipes 232 through the ventilation pipe 231 to pump air into the fan blade 222.

[0070] In the above embodiment, when cooling the inside of the box body 100, through the rotating cooling movement of the cooling fan 221, the flow rate of the hot air inside the box body 100 can be accelerated, and at the same time, the cold air outside is sent into the box body 100 for ventilation and air exchange inside the box body 100. Air is introduced into the air guide pipe 233 through an air pump, so that the gas enters the ventilation pipe 231, and then is split into four branch pipes 232 through the ventilation pipe 231 to pump air into the fan blade 222. Through the cleaning head 223, the air around the ventilation plate 2111 can be driven to make a turbulent flow, increasing the contact area between the hot air inside the box body 100 and the cold air outside. At the same time, the brush at the bottom of the cleaning head 223 can clean the dust on the ventilation plate 2111 to avoid dust clogging the through holes. The heat dissipation component 200 is located at the top of the box body 100, which can shorten the contact path between the external cold air and the hot air inside the box body 100, accelerate the contact speed between the hot air inside the box body 100 and the external cold air, and improve the heat dissipation efficiency.

[0071] ]]In some embodiments of the present invention, as Figures 10 to 12 shown, one side of each fan blade 222 is open, and a gas soft bag 2221 is fixed inside each fan blade 222. The air outlet end of one branch pipe 232 extends into a gas soft bag 2221, and the connection between the branch pipe 232 and the gas soft bag 2221 is sealed and fixed. The inside of the gas soft bag 2221 is inflated through the branch pipe 232 to make the gas soft bag 2221 expand.

[0072] One end of the cleaning head 223 extends into the gas soft bag 2221, and a valve is fixed on the cleaning head 223.

[0073] It should be noted that when the gas soft bag 2221 is inflated, the valve on the cleaning head 223 is in the closed state, and when the gas soft bag 2221 is inflated, the gas will not leak from the cleaning head 223.

[0074] Specifically, as Figure 12 shown, after the gas soft bag 2221 is inflated and expanded, the gas soft bag 2221 can abut against the adjacent fan blade 222.

[0075] In the above embodiment, when encountering bad weather such as strong wind or dust, dust and impurities easily enter the box body 100 from the ventilation plate 2111. The air pump is used to inflate the air duct 233, and the gas enters the air pipe 231 and then enters the gas soft bag 2221 through the branch pipe 232 to make the gas soft bag 2221 expand. After each gas soft bag 2221 expands, one gas soft bag 2221 abuts against an adjacent fan blade 222 to fill the gap between the fan blades 222, which can prevent external dust or impurities from entering the box body 100. After the bad weather, the gas in the gas soft bag 2221 is deflated to reset the gas soft bag 2221;

[0076] When heat dissipation treatment is performed on the box body 100, the valve on the cleaning head 223 is in the open state, and the air pump is used to extract air from the gas soft bag 2221 through the air duct 233 to generate negative pressure gas at the cleaning head 223, disturbing the gas flow trajectory around the ventilation plate 2111. At this time, the gas soft bag 2221 remains in its initial state unchanged and does not affect the gas flow in the cleaning head 223, increasing the functionality of use.

[0077] In some embodiments of the present invention, as Figures 13 to 16 shown, a plurality of air inlet cylinders 224 are evenly spaced and fixed near the ventilation plate 2111 on each fan blade 222;

[0078] The air inlet cylinder 224 is a hollow cylinder with both ends open, and one end of it extends into the gas soft bag 2221, and a valve is fixed on each air inlet cylinder 224;

[0079] A cleaning soft bag 2241 is fixed at the free end of each air inlet cylinder 224, and a cleaning part 2242 is fixed at the bottom of the cleaning soft bag 2241. The cleaning part 2242 can contact the surface of the ventilation plate 2111. In this way, when the fan blade 222 rotates, the cleaning part 2242 can also clean the ventilation plate 2111.

[0080] It should be noted that when the valve on the air inlet cylinder 224 is open, the valve on the cleaning head 223 is in the closed state.

[0081] Specifically, as Figure 15As shown, by repeatedly inflating and deflating the gas soft bag 2221 through the air duct 233, the cleaning soft bag 2241 expands and contracts repeatedly, enabling the cleaning part 2242 to extend into the through hole of the ventilation plate 2111. After expansion, the cleaning soft bag 2241 drives the cleaning part 2242 to extend into the through hole in the ventilation plate 2111, capable of flushing away the dust and impurities in the through hole of the ventilation plate 2111, and better cleaning the through hole of the ventilation plate 2111.

[0082] It should be noted that by repeatedly inflating and deflating the gas soft bag 2221 through the air duct 233, at this time, the valve on the air inlet cylinder 224 is opened, and gas can enter the cleaning soft bag 2241, causing the cleaning soft bag 2241 to expand and contract repeatedly.

[0083] Specifically, as Figure 15 shown, the cleaning part 2242 is a rubber bladder, and its interior is filled with gravity powder. A cleaning cloth is fixed to the outside of the cleaning part 2242, and the cleaning cloth can contact the inner wall surface of the through hole of the ventilation plate 2111.

[0084] It should be noted that the cleaning part 2242 is filled with gravity powder. As the gas soft bag 2221 expands and contracts, it can drive the cleaning part 2242 to expand and contract synchronously, enabling the cleaning part 2242 to extend into the through hole of the ventilation plate 2111. Under the impact of the cleaning part 2242, the contact force with the through hole in the ventilation plate 2111 can be increased, and the ventilation plate 2111 can be better cleaned.

[0085] In the above embodiment, when cleaning the through hole of the ventilation plate 2111, the air duct 233 is inflated and deflated to the air pipe 231, and then each gas soft bag 2221 is inflated and deflated through the branch pipe 232. At this time, the valve on the air inlet cylinder 224 is in the open state, and the valve on the cleaning head 223 is in the closed state. The gas in the gas soft bag 2221 enters the cleaning soft bag 2241, causing the cleaning soft bag 2241 to expand and contract repeatedly. When the cleaning soft bag 2241 expands, it can drive the cleaning part 2242 to extend into the through hole of the ventilation plate 2111. The dust and impurities in the through hole of the ventilation plate 2111 are cleaned by the cleaning cloth. At the same time, the gas soft bag 2221 expands and contracts repeatedly, continuously impacting the adjacent fan blades 222, causing the fan blades 222 to vibrate, which can increase the contact force between the cleaning part 2242 and the ventilation plate 2111, improve the cleaning efficiency of the ventilation plate 2111. After the rotation of the cooling fan 221 pauses for a period of time, at this time, the cleaning part 2242 is located above the through hole of the ventilation plate 2111. Repeat the above actions to extend the cleaning part 2242 into the through hole of the ventilation plate 2111, and the through hole of the ventilation plate 2111 can be completely cleaned, improving the ventilation and heat dissipation efficiency in the box body 100.

[0086] In some embodiments of the present invention, as Figures 2 to 17As shown, there are multiple heat dissipation parts 220 and multiple ventilation plates 2111. One heat dissipation part 220 is located above one ventilation plate 2111.

[0087] The air intake part 230 further includes a main pipeline 234. The air intake end of the main pipeline 234 is fixed to the air pump, and there are multiple air outlet ends of the main pipeline 234. One air outlet end of the main pipeline 234 is fixed to the air intake end of one air duct 233.

[0088] A sound insulation board 212 is fixed in the heat dissipation groove 211. The sound insulation board 212 is a honeycomb-shaped plate body, which can play a role in sound insulation and is composed of multiple holes evenly spaced on the plate body. The sound insulation board 212 is located above the heat dissipation part 220.

[0089] In the above embodiment, by providing one main pipeline 234, air can be respectively introduced into multiple air ducts 233, reducing the driving source and saving the use cost. At the same time, the provided sound insulation board 212 can achieve the sound insulation effect without affecting the normal heat dissipation movement of the heat dissipation part 220.

[0090] In some embodiments of the present application, as Figures 1 to 19 shown, it further includes a protection component 300. The protection component 300 is used to protect the equipment to avoid damage to the equipment caused by high-altitude falling objects.

[0091] The protection component 300 includes a protection board 310 and a collection tank 320.

[0092] The protection board 310 is a plate body with an isosceles trapezoid cross-section, and it is fixed to the shielding board 210 through a bracket. A through groove is opened on the protection board 310, and an anti-falling soft pad 311 is fixed in the through groove of the protection board 310. The anti-falling soft pad 311 is convenient for providing buffering for high-altitude falling objects. The anti-falling soft pad 311 can provide a certain buffering effect for high-altitude falling objects and reduce the impact force of high-altitude falling objects.

[0093] There are two collection tanks 320. One collection tank 320 is fixed in the direction of one waist edge of the protection board 310. The collection tank 320 is used to collect rainwater. A diversion pipe 322 is fixed at the bottom of the collection tank 320, and the free end of the diversion pipe 322 can extend into the water collection tank to collect the rainwater in the water collection tank, which is convenient for irrigating plants in the community environment, reducing the use of water resources and making reasonable use of natural resources.

[0094] Specifically, as Figure 18 and Figure 19As shown, a fixed clamping strip 321 is fixed near the protective plate 310 on each of the collection grooves 320. A fixed clamping groove that cooperates with the fixed clamping strip 321 is formed on the protective plate 310. The collection groove 320 is detachably connected to the protective plate 310. The fixed clamping strip 321 can be slidably clamped in the fixed clamping groove, and the collection groove 320 is positioned on the protective plate 310 by using frictional force, which is convenient for disassembly and maintenance and has a low cost.

[0095] In the above embodiment, through the provided protection assembly 300, an object falling from a height falls on the anti-fall soft pad 311. The anti-fall soft pad 311 gives a certain buffering force to the falling object, which can reduce the damage degree of the falling object from a height to the equipment and improve the safety of use. Through the provided collection groove 320, rainwater can be collected and the collected rainwater can be sent into the water collection tank, which is convenient for recycling the rainwater, rationally utilizes natural resources, and can realize the protection against falling objects from a height and the rational utilization of natural resources.

[0096] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
