Description

Technical Field

[0001] This utility model relates to the technical field of transformer cooler cleaning equipment, specifically to a descaling device for transformer coolers. Background Technology

[0002] Transformers generate a large amount of heat during operation, and to ensure their normal operation, they are usually equipped with coolers to reduce the temperature. After long-term use, a large amount of lint, dust, and other dirt accumulates on the inlet air grille and the filter screen of the fan outlet of the transformer cooler. This dirt not only affects the heat dissipation effect of the cooler and reduces the operating efficiency of the transformer, but may also cause the transformer to be damaged due to overheating, seriously affecting the stable operation of the power system.

[0003] Currently, cleaning transformer coolers mainly relies on manual cleaning or the use of simple cleaning tools. Manual cleaning is inefficient, labor-intensive, and rarely achieves satisfactory cleaning results. Existing simple cleaning tools have limited functionality, only capable of cleaning certain areas of the cooler and failing to comprehensively and effectively remove dirt.

[0004] In related fields, there are also some patented technologies for equipment cleaning. For example, patent CN119617959A discloses an "automatic cleaning device for transformer coolers," which mainly cleans by spraying water. However, this method is not suitable for equipment like transformer coolers, which have high waterproof requirements, and may cause damage to the equipment. Another example is patent CN111088499A, which provides a "descaling device for transformer coolers," which uses mechanical brushing. However, the brushing force is difficult to control, which may damage the cooler components, and it is not effective at cleaning some stubborn dirt.

[0005] Therefore, there is an urgent need to design a descaling device for transformer coolers to solve the problems of unreasonable cleaning methods, easy damage to equipment, and poor cleaning effect in the existing technology, so as to achieve efficient and safe cleaning of the inlet air grille and fan outlet filter screen of transformer coolers.

[0030] In specific implementation of this utility model, such as Figures 1 to 6 As shown, the working platform 1 serves as the basic support platform for the entire device. Multiple support legs 101 are welded to the bottom for stability, and a slot 102 is provided in the middle to accommodate the transformer cooler 7. The power mechanism 2 includes a drive motor 201, a gear steering gear 202, a transmission shaft 203, and a screw jack 204. The drive motor 201 is connected to the gear steering gear 202 via a coupling, and the screw jack 204 is connected to both sides of the gear steering gear 202 via the transmission shaft 203.

[0031] The front cleaning mechanism 3 includes a fixing block 301, a crossbar seat 302, a crossbar frame 303, and a cleaning strip 304. The cleaning strip 304 is assembled on the crossbar frame 303, and the crossbar frame 303 is connected to the crossbar seat 302 through a snap fastener 305 and a snap fastener seat 306. The crossbar seat 302 is fixed to the fixing block 301 by screws.

[0032] The rear cleaning mechanism 4 includes a cleaning roller brush 401, a rack 402, a slide rail 403, a limit cap 404, a slider 405, a support plate 406, a bearing 407, and a gear 408. The cleaning roller brush 401 has a cleaning soft rubber coating on its surface and gears 408 are mounted at both ends. The gears 408 are rotatably mounted in the bearing 407. The bearing 407 is connected to the slider 405 through the support plate 406. The slider 405 is slidably mounted in the longitudinally placed slide rail 403. The rear part of the gear 408 is meshed with the longitudinally placed rack 402.

[0033] One end of the connecting rod 5 is fixed to the fixed block 301, and the other end is fixed to the slider 405, which is used to connect the front cleaning mechanism 3 and the rear cleaning mechanism 4.

[0034] In addition, such as Figure 7As shown in the illustration, this embodiment also provides a schematic diagram of the positions of the transformer 6 and the transformer cooler 7 during specific descaling and cleaning. The transformer 6 is equipped with a matching transformer cooler 7 at its rear, which is placed in the slot 102 of the working base 1. The transformer cooler 7 includes a front air grille 701 and a fan outlet 702.

[0035] First, place the transformer cooler 7 in the slot 102 of the working base 1, ensuring that the front air grille 701 and the fan outlet 702 are aligned with the front cleaning mechanism 3 and the rear cleaning mechanism 4, respectively.

[0036] Then, the drive motor 201 is started, and the motor shaft of the drive motor 201 drives the gear steering gear 202 to rotate through the coupling. The gear steering gear 202 transmits the rotational force to the screw jacks 204 on both sides through the transmission shaft 203.

[0037] The lead screw of the screw jack 204 rises under the action of rotational force, driving the lifting platform 205 at the top of the lead screw to rise. The fixed block 301 and the crossbar seat 302 arranged on the lifting platform 205 rise accordingly, which in turn drives the crossbar frame 303 equipped with cleaning strips 304 to rise. The cleaning strips 304 are made of rubber with anti-corrosion treatment on the surface. They clean the lint and other dirt on the surface of the front air grille 701 by contacting it, avoiding physical damage to the cooler components.

[0038] Since the rear cleaning mechanism 4 is integrally connected to the front cleaning mechanism 3 via the connecting rod 5, the rear cleaning mechanism 4 rises simultaneously with the front cleaning mechanism 3. The connecting rod 5 drives the slider 405 to slide upward along the slide rail 403. The slider 405 is integrally connected to the shaft seat 407 with gear 408 via the bracket plate 406, thereby causing the gear 408 to move upward along the rack 402. As the gear 408 rises, it drives the cleaning roller brush 401 to rotate. The cleaning roller brush 401 is made of rubber with an anti-corrosion surface treatment and cleans lint and other dirt by rolling and contacting the filter screen of the fan outlet 702.

[0039] At this point, the upward cleaning process ends, and the downward cleaning process begins. The drive motor 201 reverses its operation, and the lead screw of the screw jack 204 descends, causing the lifting platform 205, the fixed block 301, the crossbar seat 302, and the crossbar frame 303 to descend as well. The cleaning strip 304 and the cleaning roller brush 401 then descend, cleaning the front air grille 701 and the filter screen of the fan outlet 702 again.

[0040] Repeat the above rising and falling cleaning process until the dirt on the front air grille 701 and the filter screen of the fan outlet 702 is completely removed.

[0041] The drive motor 201 is a Y2-90L-4 type three-phase asynchronous motor with a rated power of 1.5kW and a speed of 1400r / min. The gear steering gear 202 is an SJ-ZQ35 type three-way right-angle gearbox with a transmission ratio of 1:1 and an input / output shaft diameter of Φ20mm. The ball screw jack 204 is a JWB-3 type ball screw jack with a stroke of 500mm and a load of 300kg.

[0042] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
