Technical Field

[0001] The utility model relates to the technical field of high-voltage motor air duct maintenance equipment, in particular to a special tool for cleaning high-voltage motor air ducts used in chemical enterprises. Background Art

[0002] When a motor runs for a long time, sand, catkins, oil and dust will accumulate in the air duct of the motor cooler, which will greatly reduce the cooling effect and cause problems such as increased winding temperature, insulation aging and motor winding short circuit. Taking the YAKK series motors commonly used in chemical companies as an example, their cooling method is air-to-air cooling, and the length of the air duct is generally 2-4 meters. The conventional air duct cleaning method is to use a slender bamboo pole or a hard round steel head wrapped with cotton cloth to poke it into the air duct for cleaning, or to use compressed air for blowing. The above working method has the defect of not thoroughly cleaning debris. At the same time, the use of cotton cloth for cleaning will cause foreign objects such as cotton cloth to fall into the air duct. Utility Model Content

The special tool includes an air inlet hose 1, the head end of the air inlet hose 1 is connected to a compressed air source, and the end of the air inlet hose 1 is connected to a wind-powered rotating cleaning component 3 through a fixed connecting member 2. The interior of the air inlet hose 1 is connected to the interior of the wind-powered rotating cleaning component 3 through an air hole 9 in the fixed connecting member 2; the wind-powered rotating cleaning component 3 includes a rotating part connected to the fixed connecting member 2, and a cleaning part arranged at the rear of the rotating part and integrally formed with the rotating part. The compressed air source described in the present invention can be a compressed air storage tank, a compressed air pipeline or an air compressor. The compressed air generated by it enters the rotating part of the wind-powered rotating cleaning part 3 through the air inlet hose 1 and the fixed connecting part 2, and is used to drive the rotating part to rotate. During the rotation of the rotating part, the cleaning part is driven to rotate to clean the inside of the air duct; the rotating part rotates with air as the power, and the currently conventional compressed air-driven rotating parts can be used. When the compressed air drives the rotating part to rotate, the air can be sprayed into the inside of the air duct, and at the same time achieve the purpose of cleaning debris.

[0022] Furthermore, the wind-powered rotating cleaning part 3 is a cylindrical structure with a hollow interior, and a connecting step 4 is provided inside the cylindrical structure corresponding to the connection between the rotating part and the cleaning part; a plurality of vents 5 inclined toward the fixed connecting part 2 are evenly opened on the rotating part, and a brush 6 is evenly provided on the outer circumferential surface of the cleaning part. In the present utility model, the inner diameter of the cylindrical structure corresponding to the rotating part is smaller, and the inner diameter of the cylindrical structure corresponding to the cleaning part is larger; the arrangement of the vents 5 enables the rotation of the rotating part, and at the same time, its inclination toward the fixed connecting part 2 can drive the air inlet hose 1 into the air duct, so as to achieve the purpose of flexible entry into the air duct of the present utility model, and at the same time, it can also facilitate the blowing out of debris in the air duct; the present utility model is provided with a brush 6, and during use, the cleaning part rotates together with the rotating part to achieve the purpose of rotating the brush 6, further achieving the characteristic of efficient cleaning of debris.

The sleeve 7 described in the present utility model is sleeved on the end of the air inlet hose 1 and realizes a fixed connection with the air inlet hose 1; the connecting threaded hole 10 is used for the fixed connection between the fixed connection part 2 and the wind-powered rotating cleaning part 3; the connecting sleeve 8 provides an installation position for the connection between the fixed connection part 2 and the wind-powered rotating cleaning part 3 on the one hand, and on the other hand, the compressed air in the air inlet hose 1 can enter the wind-powered rotating cleaning part 3 by providing the air holes 9, and drive the rotation of the rotating part.

[0024] Furthermore, the outer diameter of the connecting sleeve 8 is smaller than the inner diameter of the cylindrical structure corresponding to the rotating part. The above arrangement not only facilitates installation, but also facilitates the passage of compressed air and the discharge of compressed air through the vent hole 5, thereby realizing the rotation of the rotating part.

The end of the air intake hose 1 is provided with a joint, which is provided with an external thread that cooperates with the internal thread 11 to achieve a quick connection between the air intake hose 1 and the fixed connector 2.

[0026] Furthermore, a sealing ring 12 is provided between the inner end face of the wind-driven rotating cleaning member 3 and the end face corresponding to the sleeve 7. By providing the sealing ring 12, it is possible to achieve a seal between the wind-driven rotating cleaning member 3 and the sleeve 7. It should be noted that the rotating portion and the cleaning portion of the wind-driven rotating cleaning member 3 described in the present invention can rotate simultaneously. Based on this, the provision of the sealing ring 12 can achieve a seal between the aforementioned two portions, and is based on the premise that the rotation of the wind-driven rotating cleaning member 3 is not affected.

[0027] Furthermore, a gasket seal 13 is provided on the outer side of the connecting step 4, and the connecting bolt 14 is connected to the connecting threaded hole 10 through the gasket seal 13.
