Description

Technical Field

[0001] This utility model belongs to the field of centrifugal blower technology, and in particular relates to an adjustable high-voltage permanent magnet synchronous motor mounting base. Background Technology

[0002] Single-stage high-speed centrifugal blowers use a motor-driven speed-increasing gearbox to boost the motor speed to the operating speed of the centrifugal impeller. This accelerates the airflow entering through the impeller inlet, which then flows through the impeller and volute, converting mechanical energy into pressure potential energy and internal energy. The air is then discharged from the volute outlet into the outlet pipe. High-efficiency permanent magnet motors are increasingly widely used due to their high power density and high operating efficiency.

[0003] High-efficiency permanent magnet synchronous motors (PMSMs) offer high power density and small size, exhibiting superior performance compared to commonly used three-phase asynchronous motors. Currently, the motor mounting brackets for commonly used centrifugal blowers are designed based on the dimensions of three-phase asynchronous motor mounting brackets. However, the standard bracket size for PMSMs is 1-2 bracket sizes smaller than that of three-phase asynchronous motors. Therefore, the mounting dimensions of three-phase asynchronous motors and PMSMs differ, and the heights of their output shafts also differ. If a three-phase asynchronous motor needs to be replaced with a PMSM, a different motor mounting bracket for the centrifugal blower must be designed. Furthermore, in the event of a failure in the PMSM, it is not possible to directly replace it with a three-phase asynchronous motor. Therefore, existing centrifugal blower motor mounting brackets suffer from poor interchangeability and insufficient versatility. Utility Model Content

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many details listed in the specification are merely to provide the reader with a thorough understanding of one or more aspects of this utility model, and these aspects can be achieved even without these specific details.

[0030] like Figure 1-7As shown, an adjustable high-voltage permanent magnet synchronous motor mounting base includes a mounting mechanism 1, a lateral adjustment mechanism 2, and a height adjustment mechanism 3. The mounting mechanism 1 includes a base plate 11 and ribs 12. The base plate 11 is horizontally arranged with two ribs spaced apart on the left and right. The ribs 12 are horizontally arranged between the two base plates 11, and their two ends are fixedly connected to the two base plates 11 respectively. The height adjustment mechanism 3 includes a support plate 31 and a lifting assembly 32. The support plate 31 is horizontally arranged and connected to the two base plates 11 through the lifting assembly 32. The support plate 31 can move up and down through the lifting assembly 32. The lateral adjustment mechanism 2 includes a connecting plate 21 and a pitch-changing assembly 22. The connecting plate 21 is horizontally arranged with two ribs spaced apart on the left and right. The two connecting plates 21 are connected to the support plate 31 through the pitch-changing assembly 22. The connecting plates 21 can move back and forth through the pitch-changing assembly 22. The pitch-changing component 22 in the lateral adjustment mechanism 2 can adjust the distance between the two connecting plates 21, thereby adjusting the relative position of the two connecting plates 21 so that the position of the two connecting plates 21 conforms to the installation dimensions of the high-voltage permanent magnet synchronous motor to be replaced; the height adjustment mechanism 3 can adjust the height position of the lateral adjustment mechanism 2 so that the height of the output shaft of the high-voltage permanent magnet synchronous motor corresponds to the height of the half coupling of the input shaft of the high-speed speed-increasing gearbox; through the lateral adjustment mechanism 2 and the height adjustment mechanism 3, the high-voltage permanent magnet synchronous motor can be interchanged with the three-phase asynchronous motor.

[0031] The top surface of the base plate 11 has vertically through mounting holes 111 spaced apart on the left and right sides; the two connecting plates 21 expose the mounting holes 111. The base plate 11 is fixedly connected to the motor mounting base of the centrifugal blower by bolts passing through the mounting holes 111 of the base plate 11.

[0032] The lifting assembly 32 comprises four components, respectively located on the left and right sides of the top surface of each base plate 11, including studs 321, movable components 322, and lifting components 323. The studs 321 are vertically arranged, with their bottom ends fixedly connected to the base plate 11. The movable components 322 are sleeved on the studs 321, and their interiors are threadedly connected to the studs 321. The lifting components 323 are sleeved on the studs 321, with their bottom surfaces fixedly connected to the top surfaces of the movable components 322. The four corners of the support plate 31 are provided with through holes 311 corresponding to the studs 321. The diameter of the through holes 311 is larger than the diameter of the studs 321, and the support plate 31 is sleeved on the studs 321 through the through holes 311. The movable part 322 rotates and moves up and down on the stud 321 via a thread, thereby driving the lifting part 323 to move up and down. When the lifting part 323 moves upward, it can push the support plate 31 upward, causing the support plate 31 to move upward. After the lifting part 323 moves downward through the movable part 322, it presses down on the connecting plate 21, causing the connecting plate 21 to move downward, thereby realizing the up and down adjustment of the support plate 31.

[0033] The lifting assembly 32 also includes a locking nut 324; the locking nut 324 is threadedly connected to the stud 321 and is located above the support plate 31. After the height of the support plate 31 is adjusted by the moving part 322 and the lifting part 323, the locking nut 324 is screwed in to restrict the support plate 31.

[0034] The variable pitch assembly 22 includes a slide rail 221 and a slide table 222. The slide rail 221 is horizontally arranged on the support plate 31, with multiple slide rails spaced apart on the left and right. The bottom surfaces of the two connecting plates 21 are slidably mounted on the front and rear sides of the slide rail 221 via the slide table 222. The two connecting plates 21 can move back and forth on the slide rail 221 via the slide table 222, thereby adjusting the distance and position of the two connecting plates 21 to correspond to the installation dimensions of the high-voltage permanent magnet synchronous motor.

[0035] The connecting plate 21 has a through groove 213 on its bottom surface; the slide 222 is fixedly installed in the through groove 213. By setting the slide 222 in the through groove 213, the original height of the entire device can be reduced, preventing the original height of the entire device from being too high, which would cause the output shaft of the high-voltage permanent magnet synchronous motor to be too high above the height of the half-coupling of the high-speed gearbox.

[0036] The slide rail 221 is provided in two parts. The two slide rails 221, together with the slide table 222, can ensure the movement stability of the connecting plate 21, and at the same time ensure the support performance of the connecting plate 21.

[0037] The variable pitch assembly 22 also includes a limiting plate 223; the limiting plate 223 is vertically disposed at both ends of the slide rail 221. The limiting plate 223 is used to limit the travel of the connecting plate 21 and prevent the connecting plate 21 from moving outward and falling off.

[0038] The support plate 31 has vertically penetrating horizontal channels 312 on its top left and right sides; the connecting plate 21 has vertically penetrating locking screw holes 212 on its top left and right sides; it also includes locking bolts 4; the locking bolts 4 pass vertically through the locking screw holes 212 of the connecting plate 21 and the channels 312 of the support plate 31, fixing the connecting plate 21 and the support plate 31. By passing the locking bolts 4 through the locking screw holes 212 and the horizontal channels 312, the connecting plate 21 and the support plate 31 are locked together, preventing the connecting plate 21 from moving after the high-voltage permanent magnet synchronous motor is installed or during operation.

[0039] Each of the connecting plates 21 has vertically penetrating connecting holes 211 on both the front and rear sides of its top surface. The high-voltage permanent magnet synchronous motor is fixedly connected to the connecting plate 21 by bolts passing through the pre-reserved mounting holes on the high-voltage permanent magnet synchronous motor and the connecting holes 211 on the connecting plate 21.

[0040] The working principle of this utility model is as follows:

[0041] When it is necessary to replace the three-phase asynchronous motor with a high-voltage permanent magnet synchronous motor, first remove the three-phase asynchronous motor, and then fix the base plate 11 of the mounting mechanism 1 to the centrifugal blower motor mounting base with bolts.

[0042] According to the installation dimensions of the high-voltage permanent magnet synchronous motor, the connecting plate 21 of the transverse connecting mechanism is moved on the slide rail 221 via the slide table 222 of the pitch-changing assembly 22. The relative distance and position of the two connecting plates 21 are adjusted so that the connecting holes 211 on the two connecting plates 21 correspond to the installation dimensions of the high-voltage permanent magnet synchronous motor. After the position of the connecting plate 21 is determined, the connecting plate 21 and the support plate 31 are fixed by passing the locking bolts 4 through the locking screw holes 212 of the connecting plate 21 and the horizontal channel 312 of the support plate 31, thus fixing the position of the connecting plate 21. After fixing, the high-voltage permanent magnet synchronous motor is installed on the two connecting plates 21. The high-voltage permanent magnet synchronous motor is fixedly connected to the connecting plate 21 by passing bolts through the reserved mounting holes 111 on the high-voltage permanent magnet synchronous motor and the connecting holes 211 on the connecting plate 21.

[0043] Based on the height of the output shaft of the high-voltage permanent magnet synchronous motor, rotate the moving part 322 so that the moving part 322 drives the lifting part 323 to move upward on the stud 321, so that the support plate 31 moves upward. The support plate 31 drives the connecting plate to move upward, thereby adjusting the height of the output shaft of the high-voltage permanent magnet synchronous motor and the height of the half coupling of the input shaft of the corresponding high-speed speed-increasing gearbox, thus completing the replacement of the high-voltage permanent magnet synchronous motor.

[0044] In the event of a fault in the high-voltage permanent magnet synchronous motor, the mounting mechanism 1 of this application can be directly removed so that the base plate 11 is no longer connected to the centrifugal blower motor mounting base and can be taken out, and then the three-phase asynchronous motor can be installed.

[0045] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
