Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-5 , the present utility model provides a technical solution: an auxiliary device for measuring the levelness of a circulating water pump in a power plant, including a channel steel plate 1, a mounting seat 2 is detachably connected to the upper part of the middle side of the channel steel plate 1, inverted U-shaped plates 4 are fixedly arranged at the front and rear positions of the mounting seat 2, an I-shaped plate 15 is inserted between the two inverted U-shaped plates 4, clamping plates 5 are fixedly arranged on the upper sides of the I-shaped plates 15, placing plates 6 are fixedly connected to the upper end faces of the clamping plates 5, square placing chambers 7 are opened in the placing plates 6, a level is placed between the two placing chambers 7, and a lifting component is connected between the two clamping plates 5 to adjust the distance between the two placing plates 6.

[0024] First, place the level in the two placing chambers 7. By adjusting the lifting component, move the two clamping plates 5 towards the direction of approaching each other, thereby adjusting the distance between the two placing plates 6, so as to fix the level in the placing chamber 7. Then, place the channel steel plate 1 on the measuring motor base and the outer cylinder of the large vertical water pump as needed to measure the levelness, reducing the phenomenon of errors in detection caused by too many measuring parts.

[0025] The lifting component includes an adjusting screw rod 11 rotatably connected to the middle of the mounting base 2. A lifting plate 8 is threadedly connected to the upper side of the adjusting screw rod 11. The left and right end faces of the lifting plate 8 are inclined, and sliding plates 14 are fixedly connected to both the left and right end faces. Sliding grooves 13 are formed on the opposite faces of the two clamping plates 5. The sliding plates 14 are slidably connected to the sliding grooves 13 and can freely move up and down along the sliding grooves 13. By rotating the adjusting screw rod 11, due to the sliding connection between the sliding plates 14 and the sliding grooves 13, when the lifting plate 8 moves up and down freely, it drives the two clamping plates 5 to move outward or inward simultaneously, thereby adjusting the position between the two placing plates 6, so as to conveniently and quickly fix the position of the level between the two placing chambers 7.

[0026] The lower side of the adjusting screw rod 11 is connected to a transmission shaft 10 through a bevel gear set. The transmission shaft 10 is connected to a bearing seat through a bearing, and the bearing seat is fixedly connected to the mounting base 2. An adjusting handle 9 is fixedly arranged at the rear end of the transmission shaft 10; by rotating the adjusting handle 9, the adjusting handle 9 drives the transmission shaft 10 to rotate, and the transmission shaft 10 drives the adjusting screw rod 11 to rotate through the bevel gear set, so as to adjust the lifting plate 8 to a suitable height position, facilitating the adjustment of the two placing plates 6 to a suitable distance for quickly clamping the level.
