Description

Technical Field

[0001] The utility model relates to a special tool for cleaning an air duct of a high-voltage motor cooler. Background Art

[0002] Due to the influence of surface dust and wind, powder and dust easily accumulate in the cooling ducts of high-voltage motors in power plants, causing the cooling ducts to be blocked or even clogged, which greatly reduces the cooling effect of the motor cooler, and then causes the motor winding temperature to rise, insulation aging, and even motor burnout. Therefore, it is particularly important to clean and unblock the motor cooling ducts in a timely manner. At present, there are no special cleaning tools in China for duct cleaning. Only a thin bamboo pole or a hard iron wire head wrapped with cotton cloth is used to poke into the duct for cleaning. Such simple tools often have poor cleaning effects. The accumulated powder and dust in the duct solidify and stick to the inner wall of the wind belt, which cannot be effectively removed. Therefore, the present invention provides a special tool for cleaning the ducts of high-voltage motor coolers to solve the above problems. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide a special tool for cleaning the air duct of a high-voltage motor cooler.

[0004] The above purpose is achieved through the following technical solutions:

[0005] A special tool for cleaning the air duct of a high-voltage motor cooler, comprising a telescopic rod, the end of which is fixed to a support platform, four outer sleeves fixed to the side of the support platform, the four outer sleeves being evenly arranged in a circle along the center of the support platform, an inner rod inserted into each outer sleeve, the inner rod slidingly engaged with the outer sleeve, the end of the inner rod fixed to a supporting arc plate, the back of the supporting arc plate being fixed with a steel sponge cleaning pad;

[0006] The support is connected to the screw rod through a bearing. The screw rod is covered with a screw sleeve. The side of the screw sleeve is hinged to one end of four connecting rods. The other end of the connecting rod is hinged to the support column on the inner rod at the corresponding position.

[0007] The special tool for cleaning the air duct of a high-voltage motor cooler is described, and the telescopic rod includes a first tube, a second tube and a third tube. The first tube is fixed to the support platform, the second tube is sleeved on the first tube, and the third tube is sleeved on the second tube. The side walls of the first tube and the second tube are evenly provided with multiple positioning holes. The second tube is threadedly connected with a second bolt, and the second bolt passes through the positioning hole on the first tube. The third tube is threadedly connected with a third bolt, and the third bolt passes through the positioning holes on the second tube and the first tube.

[0008] The arc abutting plate is connected with the steel wire sponge cleaning pad through the primary and secondary magic tape. Advantages

[0009] 1. The device can be inserted into the cooler air duct to clean the accumulated powder and dust in the air duct, and the telescopic rod can be telescoped to facilitate the insertion of the device into the cooler air duct.

[0010] 2. The position of the arc abutting plate can be adjusted according to the different hole diameters of the inner wall of the cooler air duct, so that the steel wire sponge cleaning pad can tightly abut against the inner wall of the air duct, and the accumulated powder attached to the inner wall of the air duct can be effectively removed after back and forth operation, thereby greatly improving the cleaning effect and efficiency.

DETAILED DESCRIPTION

[0017] As Figure 1-5 shown, a high-voltage motor cooler air duct cleaning special tool comprises a telescopic rod 6, the end of the telescopic rod is fixed with a support 9, the side surface of the support is fixed with four outer sleeves 10, the four outer sleeves are uniformly arranged along the center of the support in a circle, an inner rod 11 is inserted into each outer sleeve, the inner rod is in sliding fit with the outer sleeve, the end of the inner rod is fixed with an arc abutting plate 4, and the back of the arc abutting plate is fixed with a steel wire sponge cleaning pad 5.

[0018] The arc-supporting plate and the steel sponge cleaning pad are connected by a Velcro tape. The back of the arc-supporting plate is bonded with a mesh surface 8 of the Velcro tape, and the steel sponge cleaning pad is bonded with a hook surface 7 of the Velcro tape, which can fix the steel sponge cleaning pad.

[0019] The support is connected to the screw 1 through a bearing. The screw is covered with a screw sleeve 2. The side of the screw sleeve is hinged to one end of four connecting rods 3. The other end of the connecting rod is hinged to the support 13 on the corresponding inner rod. Each inner rod is fixed with a support, which passes through the sliding hole 12 on the outer sleeve.

[0020] The telescopic rod includes a first tube 61, a second tube 64 and a third tube 65. The first tube is fixed to the support platform, the second tube is sleeved on the first tube, and the third tube is sleeved on the second tube. The side walls of the first tube and the second tube are evenly provided with a plurality of positioning holes 66. The second tube is threadedly connected to a second bolt 62, and the second bolt passes through the positioning hole on the first tube. The third tube is threadedly connected to a third bolt 63, and the third bolt passes through the positioning holes on the second tube and the first tube.

[0021] Working principle: When in use, the device needs to be adjusted to the position against the arc plate so that its wire sponge cleaning pad can contact the inner wall of the air duct with a certain pressure. A nut is welded at the end of the screw. Turn the screw, and the screw is threadedly connected to the sleeve, so that the screw moves downward. Since the sleeve is hinged to each inner rod through a connecting rod, the inner rod is pushed to slide under the push of the connecting rod, so that its four against the arc plates move outward at the same time, so that the size of the formed cleaning ring changes, until the formed cleaning ring is adjusted to be slightly larger than the inner wall of the air duct and stops. Remove the second bolt and the third bolt, and the positioning holes on the first and second tubes correspond to each other. Slide the second tube to adjust the length of the telescopic rod. After adjustment, tighten the second bolt, and the second bolt passes through the positioning hole of the first tube, and then slide the third tube. After sliding, tighten the third bolt, and the third bolt passes through the positioning holes of the second and first tubes. After adjusting the telescopic rod, extend the device into the air duct so that its wire sponge cleaning pad is close to the inner wall of the air duct. After running back and forth, it can effectively remove the accumulated powder attached to the inner wall of the air duct, greatly improving the cleaning effect and efficiency.
