[0029] Refer to Figure 1 The utility model provides a technical scheme: fan installation verticality control device, including fan installation cylinder 1 and calibration block 2.

[0030] The overall specific setting and function are specifically introduced below.

[0031] In the embodiment: the lateral wall of calibration block 2 is fixedly connected with hollow round plate 6, the outer surface of hollow round plate 6 is fixedly installed with center point 7, the both sides of center point 7 are fixedly connected with horizontal line 8, and the inside of hollow round plate 6 is equipped with the aqueous solution of half volume of hollow round plate 6. The characteristic that liquid keeps horizontal under the action of gravity is utilized to assist in judging verticality, and the calibration work after the installation of fan installation cylinder 1 is facilitated, and the installation efficiency of fan installation cylinder 1 is improved to a certain extent. The aqueous solution is green aqueous solution. The green aqueous solution in hollow round plate 6 is evenly distributed in hollow round plate 6. The surface of hollow round plate 6 is evenly provided with a plurality of outer scale lines 9. The scale display of outer scale line 9 is abnormal, and it indicates that fan installation cylinder 1 has verticality deviation. The side, away from hollow round plate 6, of calibration block 2 is provided with reserved slot 5 with V-shaped cross section. The reserved slot 5 with V-shaped cross section provided on calibration block 2 can improve the tightness of the adhesion of cylindrical structure fan installation cylinder 1 in the adhesion process. The arc surface of hollow round plate 6 is provided with a plurality of side scale lines 10. The installation personnel can judge the degree of verticality deviation according to the scale of outer scale line 9 and side scale line 10, so as to determine the direction and amplitude of adjustment. Hollow round plate 6 is made of acrylic material. Hollow round plate 6 adopts acrylic material, and because it has good transparency, the installation personnel can clearly observe the liquid level of aqueous solution and the condition of scale line.

[0032] Specifically, the lower surface of the calibration block 2 is fixedly connected with a connecting rope 3. By arranging the connecting rope 3, the carrying work of the calibration block 2 is facilitated. The lower end of the connecting rope 3 is fixedly connected with an elastic ring 4. The elastic ring 4 is suitable for the wearing work of different persons, and the phenomenon that the calibration block 2 falls during the high-altitude operation is avoided.

[0033] The working principle is that during the installation process of the fan tower drum, the verticality control device can effectively play a role. First, the calibration block 2 is tightly attached to the fan installation drum 1 to be installed, and the calibration block 2 is tightly attached to the position of the fan installation drum 1 where the verticality needs to be detected. When the hollow circular plate 6 is filled with a half-volume green aqueous solution, the liquid is used to assist in judging the verticality by using the characteristic of keeping horizontal under the action of gravity. If the fan installation drum 1 is in a vertical state, the green aqueous solution in the hollow circular plate 6 will be evenly distributed in the hollow circular plate 6. At this time, the horizontal line 8 on both sides of the center point 7 should be parallel to the liquid level of the aqueous solution, and the scale display of the outer scale line 9 and the side scale line 10 should be at a specific standard position. The installer can directly judge whether the fan installation drum 1 is vertical by observing the relative position relationship between the liquid level of the aqueous solution and the horizontal line 8, and the scale display of the outer scale line 9 and the side scale line 10 being covered by the aqueous solution or the corresponding scale. If it is found that the liquid level of the aqueous solution is not parallel to the horizontal line 8, or the scale display of the outer scale line 9 and the side scale line 10 is abnormal, it indicates that the fan installation drum 1 has a verticality deviation. For example, if the liquid level of the aqueous solution on one side is higher than the horizontal line 8, it indicates that the fan installation drum 1 on that side is relatively high and needs to be adjusted. At this time, the installer can judge the degree of verticality deviation according to the scale of the outer scale line 9 and the side scale line 10, so as to determine the direction and amplitude of adjustment. For larger deviations, professional tools may be needed to make large adjustments to the position of the fan installation drum 1. For smaller deviations, the fan installation drum 1 can be adjusted to a vertical state by fine-tuning the installation components. During the adjustment process, the change of the liquid level of the aqueous solution and the scale line is continuously observed until the fan installation drum 1 is vertical, the liquid level of the aqueous solution is parallel to the horizontal line 8, and the scale display of the outer scale line 9 and the side scale line 10 returns to the standard state. The preformed groove 5 with a V-shaped cross section on the calibration block 2 can improve the tightness of the fitting between the cylindrical structure of the fan installation drum 1 and the calibration block 2 during the fitting process, and can make the calibration block 2 and the fan installation drum 1 keep parallel state, ensuring the reliability of the verticality detection. The hollow circular plate 6 is made of acrylic material, which has good transparency, so that the installer can clearly observe the liquid level of the aqueous solution and the scale line, improving the detection efficiency. The connecting rope 3 is set to facilitate the carrying work of the calibration block 2. The elastic ring 4 is suitable for wearing work of different personnel, avoiding the phenomenon of falling of the calibration block 2 during the high-altitude operation process, and improving the safety of the use of the calibration block 2. By setting the above structure, the liquid is used to assist in judging the verticality by using the characteristic of keeping horizontal under the action of gravity, which facilitates the calibration work after the installation of the fan installation drum 1 outdoors, and improves the installation efficiency of the fan installation drum 1 to a certain extent.
