Description

Technical Field

[0001] This utility model relates to the field of transformer housing technology, specifically a water-washable dust-removing protective housing for dry-type transformers. Background Technology

[0002] A transformer is a static electrical device that increases or decreases voltage based on the principle of electromagnetic induction without changing the frequency of alternating current. A dry-type transformer is a type of transformer whose core and windings are not immersed in insulating oil and rely on air as a cooling medium. In existing technologies, dust in the air can easily enter dry-type transformers. After long-term operation, dry-type transformers tend to accumulate a lot of dust, affecting their normal operation. However, a dry-type transformer with announcement number CN214476839U is connected to the protective shell through an air outlet duct. The top of the water-washed air outlet box is equipped with an air outlet to wash and remove dust from the air entering the protective shell, which has a better dust prevention effect.

[0003] While the aforementioned technologies can wash away dust from the air entering the protective enclosure, they have limited dust removal effectiveness. The windings and core of a dry-type transformer are the main heat-generating components, and heat dissipation depends on the flow of air between the winding gaps and the ventilation openings of the enclosure. If dust removal is not thorough, dust in the air will continue to accumulate on the winding surface, the ventilation openings of the enclosure, and the gaps of auxiliary heat dissipation components, which will lead to increased airflow resistance, reduced natural ventilation efficiency, and the inability to dissipate heat in time, causing the internal temperature of the transformer to continue to rise.

[0004] In view of this, the inventor conducted in-depth research on the aforementioned deficiencies in the prior art, which led to the creation of this case. Utility Model Content

[0005] The purpose of this invention is to provide a water-washable dust-removing protective shell for dry-type transformers, in order to solve the problem of limited dust removal effect of dry-type transformers currently on the market, as mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a water-washable dust-removing protective shell for dry-type transformers, comprising a first protective shell, a second protective shell installed on one side of the first protective shell, a water tank installed on the other side of the first protective shell, a ventilation duct provided on one side of the top of the water tank, a dust removal box provided on the other side of the top of the water tank, a water pump provided inside the water tank, and a water supply pipe provided at the output end of the water pump, one end of the water supply pipe connected to a rotary joint, a water outlet roller rotatably connected inside the dust removal box, one end of the water outlet roller and the end of the rotary joint away from the water supply pipe being connected, an atomizing nozzle connected to one side of the water outlet roller, a dust removal component for removing dust from the air provided inside the ventilation duct, and a swinging component for driving the water outlet roller to swing inside the ventilation duct.

[0007] Preferably, the dust removal assembly includes a fan installed at one end of a ventilation duct, a row of rotating rods rotatably connected inside the ventilation duct, and an air-guiding plate on one side of each rotating rod, the air-guiding plates being connected to each other by a first connecting rod.

[0008] Preferably, each of the two ends of the rotating rod is provided with a connecting plate, a support rod is provided between the connecting plates, the output end of the fan is provided with a rotating shaft, and the end of the rotating shaft away from the fan is provided with a rotating plate, and the inner part of the rotating plate away from the rotating shaft is slidably connected with a limit rod, and one end of the limit rod is provided with a sliding sleeve slidably connected to the outer surface of the support rod.

[0009] Preferably, the oscillating assembly includes a rack slidably connected to the inside of the dust collector, the rack being meshed with gears disposed on the outer surface of one end of the water outlet roller, and one end of the air guide plate being provided with a second connecting rod slidably connected to the ventilation duct and the inside of the dust collector, the second connecting rod being connected to the rack via a connecting rod.

[0010] Preferably, a slot is provided at one end of both the first protective shell and the second protective shell, and a filter plate is installed inside the slot.

[0011] Preferably, the top of the water tank has a horizontal groove, and the horizontal groove is connected to the ventilation duct and the bottom of the dust removal box.

[0012] Preferably, the ventilation duct and the dust collection box are respectively provided with interconnected through slots on the side closest to each other, and the atomizing nozzles are distributed at equal intervals.

[0013] With the above structure, the beneficial effects of the water-washable dust-removing protective shell for dry-type transformers disclosed in this utility model are as follows:

[0014] The dust removal components achieve the effect of preliminary dust removal of the air, which can avoid blockage of heat dissipation channels, ensure heat dissipation efficiency, divide the airflow into fine streams, and make the airflow evenly distributed in the water washing chamber, avoiding insufficient local water washing caused by airflow deviation.

[0015] By using water outlet rollers and rotary joints, the system achieves further dust removal by spraying air, which can accurately intercept fine dust, improve overall purification efficiency, control moisture carryover, and ensure the insulation safety of the transformer.

[0016] The oscillating component enables the water outlet roller and rotary joint to oscillate back and forth. This oscillation achieves full-coverage spraying, reduces airflow escape channels, eliminates blind spots through dynamic contact, and further improves the removal rate of small particles.

[0024] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0025] like Figures 1 to 6 As shown, this utility model relates to a water-washable dust-removing protective shell for dry-type transformers, comprising a first protective shell 1, a second protective shell 2 installed on one side of the first protective shell 1, a water tank 3 installed on the other side of the first protective shell 1, a ventilation duct 4 provided on one side of the top of the water tank 3, a dust removal box 5 provided on the other side of the top of the water tank 3, a water pump provided inside the water tank 3, and a water supply pipe 6 provided at the output end of the water pump, one end of the water supply pipe 6 connected to a rotary joint 7, a water outlet roller 8 rotatably connected inside the dust removal box 5, one end of the water outlet roller 8 connected to the end of the rotary joint 7 away from the water supply pipe 6, an atomizing nozzle 9 connected to one side of the water outlet roller 8, a dust removal component for removing dust from the air provided inside the ventilation duct 4, and a swing component for driving the water outlet roller 8 to swing inside the ventilation duct 4.

[0026] First, the dry-type transformer is installed between the first protective shell 1 and the second protective shell 2. Then, external air is guided into the dust collection box 5 through the ventilation duct 4. Then, the water pump is started to transport the clean water in the water tank 3 to the rotary joint 7 through the water supply pipe 6, and then to the water outlet roller 8. Finally, it is discharged through the atomizing nozzle 9. The atomizing nozzle 9 can evenly atomize into fine water mist. Since the atomizing nozzles 9 are evenly distributed, a fully covered atomizing area is formed. When the initial purified airflow enters from the ventilation duct 4 passes through the atomizing area, the small dust particles remaining in the airflow come into full contact with the water mist and are adsorbed by the water mist to form dust-laden water droplets, thus achieving air fine filtration. The dust-laden water droplets fall off under the action of gravity.

[0027] like Figure 1 and Figures 3 to 6 As shown, the dust removal assembly includes a fan 10 installed at one end of the ventilation duct 4. A row of rotating rods 11 are rotatably connected inside the ventilation duct 4. Each rotating rod 11 has an air-guiding plate 12 on one side. The air-guiding plates 12 are connected to each other by a first connecting rod 13.

[0028] The fan 10 at one end of the ventilation duct 4 can be started. The operation of the fan 10 generates negative pressure, which draws the dusty air from the outside into the ventilation duct 4, providing airflow power for the entire dust removal process. Then the air guide plate 12 can guide the airflow.

[0029] like Figure 3 and Figure 6 As shown, a rotating rod 11 has connecting plates 14 at both ends, a support rod 15 between the connecting plates 14, a rotating shaft 16 at the output end of the fan 10, a rotating plate at the end of the rotating shaft 16 away from the fan 10, and a limiting rod 17 is slidably connected inside the end of the rotating plate away from the rotating shaft 16. A sliding sleeve 18 is slidably connected to the outer surface of the support rod 15 at one end of the limiting rod 17.

[0030] When the fan 10 is running, the shaft 16 at its output end synchronously drives the rotating plate to rotate. The rotating plate drives the sliding sleeve 18 to slide back and forth on the outer surface of the support rod 15 through the limiting rod 17 at the end. When the sliding sleeve 18 slides, it drives the support rod 15 to move back and forth. The support rod 15 drives the rotating rod 11 connected to it to rotate through the connecting plate 14. Then, under the action of the first connecting rod 13, it drives a row of air-guiding plates 12 to swing back and forth synchronously. Through the change of the angle of the air-guiding plates 12, the airflow is evenly distributed to various areas inside the ventilation duct 4 to avoid airflow deviation. The swing of the air-guiding plates 12 will also form a shearing interception of the airflow. Large dust particles are initially intercepted due to inertia impacting the surface of the air-guiding plates 12.

[0031] like Figure 4 and Figure 5As shown, the swing assembly includes a rack 20 slidably connected to the inside of the dust collector 5. The rack 20 is meshed with gears 19 disposed on the outer surface of one end of the water discharge roller 8. One end of an air guide plate 12 is provided with a second connecting rod 21 slidably connected to the ventilation duct 4 and the inside of the dust collector 5. The second connecting rod 21 is connected to the rack 20 through a connecting rod.

[0032] When the air intake plate 12 swings, it will further drive the second connecting rod 21 to reciprocate. Then, under the action of the connecting rod, it will drive the rack 20 to reciprocate. Subsequently, under the action of the gear 19, it will drive the water outlet roller 8 to swing back and forth, thereby increasing the spray range.

[0033] like Figure 2 and Figure 3 As shown, a slot is provided at one end of both the first protective shell 1 and the second protective shell 2, and a filter plate is installed inside the slot.

[0034] The filter plate can further filter the air and further prevent dust from entering the first protective shell 1 and the second protective shell 2.

[0035] like Figures 3 to 5 As shown, a horizontal groove is provided on the top of the water tank 3, and the horizontal groove is connected to the ventilation duct 4 and the bottom of the dust removal box 5.

[0036] The horizontal groove allows dust-laden water droplets to flow back into water tank 3, enabling water resources to be recycled and reused without frequent water replenishment.

[0037] like Figures 3 to 5 As shown, ventilation duct 4 and dust collection box 5 are respectively provided with interconnected channels on the side of their proximity, and atomizing nozzles 9 are distributed at equal intervals.

[0038] This allows the airflow after initial dust removal to enter the interior of the dust collector 5 through the channel between the ventilation duct 4 and the dust collector 5.

[0039] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art of circuit board processing should be considered as not departing from the patent scope of this utility model.
