[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0022] Example 1:

[0023] Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 , a precision detection device for the installation of a dynamically adjusted fan includes a base plate 2, and also includes: a support leg base plate 1 that is detachably connected to the base plate 2; a fan body 101, which is fixedly installed on the support leg base plate 1; a plurality of detection components, which are equidistantly arranged on the base plate 2 and are used to detect the fit between the support leg base plate 1 and the base plate 2, wherein the detection component includes a sliding cavity 3 and a detection cavity 4 opened on the base plate 2, a piston plate 301 is slidably connected in the sliding cavity 3, a push rod 302 is fixedly connected to the piston plate 301, the push rod 302 passes through the sliding cavity 3 and is slidably connected to the base plate 2, gas is stored in the sliding cavity 3, a slider 401 is slidably connected in the detection cavity 4, a pressure sensor 402 is fixedly installed on the inner wall of the detection cavity 4, the sliding cavity 3 is connected to the detection cavity 4 through a second conduit 404, and a second tension spring 405 is provided in the detection cavity 4, one end of the second tension spring 405 is fixedly connected to the slider 401, and the other end is fixedly connected to the inner wall of the detection cavity 4.

[0024] An exhaust pipe 406 communicating with the detection chamber 4 is provided on the base plate 2 , and a valve switch is provided on the exhaust pipe 406 .

[0025] It also includes a tension spring 303, which is arranged in the sliding cavity 3. One end of the tension spring 303 is fixedly connected to the inner wall of the sliding cavity 3, and the other end is fixedly connected to the piston plate 301.

[0026] A conduit 1 403 communicating with the sliding cavity 3 is provided on the base plate 2 , and one-way valves are provided on the conduit 1 403 and the conduit 2 404 .

[0027] Multiple bolts 201 are evenly spaced and fixedly connected on both sides of the top of the base plate 2. A plug hole matching the bolt 201 is opened on the leg bottom plate 1. The bolt 201 is inserted into the plug hole. A nut 202 is threadedly connected to the bolt 201, and the nut 202 fits the surface of the leg bottom plate 1.

[0028] Before installing the fan body 101, the stretched tension spring 1 303 automatically resets under its own resilience, and at the same time pulls the piston plate 301 to slide upward in the sliding chamber 3 to reset, so that the piston plate 301 pushes the push rod 302 out of the sliding chamber 3. At the same time, when the piston plate 301 slides upward in the sliding chamber 3, it can draw external air into the sliding chamber 3 through the conduit 1 403.

[0029] When installing the fan body 101, the fan body 101 can be easily installed on the base plate 2 (such as Figure 1 、 Figure 2 shown);

[0030] During the installation process, when the support leg bottom plate 1 gradually fits with the base plate 2, the push rod 302 will gradually move into the sliding cavity 3 under the push of the support leg bottom plate 1. At the same time, when the push rod 302 gradually moves into the sliding cavity 3, it pushes the piston plate 301 to move downward and stretches the tension spring 1 303. At this time, the gas sucked into the sliding cavity 3 is squeezed by the piston plate 301 and filled into the detection cavity 4 through the conduit 2 404, thereby causing the gas filled in the detection cavity 4 to push the slider 401 to move downward. When the slider 401 is against the pressure sensor 402, the pressure sensor The device 402 measures the distribution of the contact pressure between the support leg base plate 1 and the base plate 2, and analyzes the contact pressure data between the support leg base plate 1 and the base plate 2. If the pressure distribution is uniform, it means that the fit is good. If there is uneven pressure distribution or the pressure values detected by multiple pressure sensors 402 have a large difference, it means that the fit is poor. This ensures the installation quality and operational safety of the fan body 101, can not only reduce the loosening of fasteners and reduce maintenance costs, but also reduce the stress and wear of components, extend the service life of the equipment, and improve the reliability of the equipment.

[0031] Example 2:

[0032] Reference Figure 1 、 Figure 4 、 Figure 5 A precision detection device for the installation of a dynamic fan is basically the same as that of Example 1. Furthermore, the detection component further includes a displacement sensor 304, which is fixedly mounted on the inner wall of the sliding cavity 3;

[0033] When the piston plate 301 moves downward under the push of the push rod 302, the distance the piston plate 301 moves downward can be detected through the displacement sensor 304, so as to obtain the value of the downward movement of the piston plate 301, and then the multiple measured values are compared. If the difference range of the multiple values is small, it means that the fit is good. If the difference range of the multiple values is large, it means that the fit is not good. Through the comprehensive application of the above methods, it is possible to more accurately detect the fit between the support leg bottom plate 1 and the base plate 2, thereby ensuring the installation quality and operation safety of the fan body 101.

[0034] Example 3:

[0035] Reference Figure 2 、 Figure 3 A precision detection device for the installation of a dynamic blower is basically the same as that of Example 1. Furthermore, an exhaust pipe 406 connected to the detection chamber 4 is provided on the base plate 2, and a valve switch is provided on the exhaust pipe 406;

[0036] After completing the test of the fit between the support leg bottom plate 1 and the base plate 2, the valve switch on the exhaust pipe 406 is opened to allow the gas to be discharged from the detection chamber 4 through the exhaust pipe 406. When the gas is discharged from the detection chamber 4, the stretched tension spring 2 405 is reset under its own rebound force, and at the same time, the slider 401 can be pulled to slide upward in the detection chamber 4 to reset, so that the slider 401 is separated from the pressure sensor 402, avoiding long-term excessive pressure, which may cause damage to the pressure sensor 402, thereby extending the service life of the pressure sensor 402.

[0037] The above description is merely a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention.
