[0034] Embodiment 1

[0035] As Figure 1-6As shown in the figure, the present utility model provides a technical solution: a centrifugal fan assembly base, including a base 1, a fixed column 2 fixedly installed on the upper part of the base 1, a placement plate 4 slidably connected to the outer wall of the fixed column 2, a connecting plate 5 fixedly connected to the upper part of the placement plate 4, a movable plate 6 fixedly connected to the upper part of the connecting plate 5, a top plate 7 fixedly connected to the top of the fixed column 2, a centrifugal fan body 8 arranged on the upper part of the placement plate 4, and a connecting component 3 arranged under the lower part of the top plate 7. The connecting component 3 includes a disassembly and assembly mechanism 31 arranged under the lower part of the top plate 7. A moving mechanism 32 is arranged under the lower part of the top plate 7. The movable plate 6 is slidably connected to the outer wall of the fixed column 2. The disassembly and assembly mechanism 31 includes a first hydraulic cylinder 311 fixedly installed on the upper part of the base 1. An installation plate 312 is arranged on the upper part of the placement plate 4. A convex column 313 is fixedly connected to the bottom of the installation plate 312. A clamping groove 314 is opened in the front of the convex column 313. A convex groove 315 is opened in the upper part of the placement plate 4. A first sliding groove 316 is opened in the front of the placement plate 4. A first sliding rod 317 is fixedly connected to the inner wall of the first sliding groove 316. A first sliding block 318 is slidably connected to the outer wall of the first sliding rod 317. A first spring 319 is fixedly connected to the inner wall of the first sliding groove 316. A connecting rod 3110 is fixedly connected to the outside of the first sliding block 318. One end of the connecting rod 3110 is movably connected to a clamping rod 3111. A pull rod is fixedly connected to the outer end of the clamping rod 3111. A second spring 3112 is fixedly connected to the outside of the connecting rod 3110. A positioning groove 3113 is opened in the side wall of the movable plate 6. A threaded groove 3116 is opened in the inner wall of the positioning groove 3113. A positioning block 3114 is clamped in the inner wall of the positioning groove 3113. A sound insulation plate 3117 is fixedly connected to one side of the positioning block 3114. A bolt 3115 is threadedly connected to the inside of the positioning block 3114.

[0036] In this embodiment, the convex column 313 is slidably connected to the inner wall of the convex groove 315, and the installation plate 312 is fixedly installed with the bottom of the centrifugal fan body 8.

[0037] Furthermore, the clamping rod 3111 is clamped with the clamping groove 314. One end of the first spring 319 is fixedly connected to the first sliding block 318. Through the cooperation of the installation plate 312, the convex column 313, the clamping groove 314, the convex groove 315, the first sliding groove 316, the first sliding rod 317, the first sliding block 318, the first spring 319, the connecting rod 3110, the clamping rod 3111, and the second spring 3112, it is convenient for manual disassembly of the installation plate 312, so as to facilitate manual maintenance and repair of the centrifugal fan body 8 fixedly installed on the upper part of the installation plate 312, thereby increasing the applicability of the device.

[0038] Furthermore, one end of the second spring 3112 away from the connecting rod 3110 is fixedly connected to the pull rod.

[0039] Furthermore, the bolt 3115 is adapted to the threaded groove 3116. The output end of the first hydraulic cylinder 311 is fixedly connected to the placing plate 4.

[0040] When it is necessary to disassemble the mounting plate 312, the worker only needs to hold the pull rod and pull the clamping rod 3111 outwards by hand, so that the clamping rod 3111 is separated from the clamping groove 314. Subsequently, under the action of the elastic force of the first spring 319, the first slider 318 can move in the first chute 316 through the first sliding rod 317. Thus, the connecting rod 3110 fixedly connected to the outside of the first slider 318 can move synchronously, and the connecting rod 3110 can stay outside the convex column 313. Then, the mounting plate 312 can be taken outwards by hand, which is convenient for workers to repair and maintain the centrifugal fan body 8 fixedly installed on the upper part of the mounting plate 312. Furthermore, the applicability of the device is increased. And the height of the placing plate 4 can be adjusted by the first hydraulic cylinder 311, so that the height of the centrifugal fan body 8 can be adjusted, further increasing the applicability of the device.

[0041] Embodiment 2

[0042] On the basis of Embodiment 1, a preferred embodiment of the centrifugal fan assembly base provided by the present utility model is as Figures 1 to 6 shown: The moving mechanism 32 includes a second hydraulic cylinder 322 fixedly installed on the inner wall of the base 1. The output end of the second hydraulic cylinder 322 is fixedly connected to a bottom plate 321. An installation column 323 is movably connected inside the bottom plate 321. A first installation block 324 is fixedly connected to the side wall of the installation column 323. The first installation block 324 is movably connected to a support rod 325 through a pin. A second chute 326 is opened on the upper part of the bottom plate 321. A second sliding rod 327 is fixedly connected to the inner wall of the second chute 326. A second slider 328 is slidably connected to the outer wall of the second sliding rod 327. A third spring 329 is fixedly connected to the inner wall of the second chute 326. A second installation block 3210 is fixedly connected to the upper part of the second slider 328. A moving wheel 3211 is arranged at the bottom of the installation column 323.

[0043] In this embodiment, the bottom plate 321 is slidably connected to the inner wall of the base 1.

[0044] Further, the bottom of the support rod 325 is movably connected to the second mounting block 3210 through a pin. One end of the third spring 329 is fixedly connected to the second slider 328. Through the cooperation of the bottom plate 321, the second hydraulic cylinder 322, the mounting column 323, and the moving wheels 3211, relative movement between the base 1 and the ground can occur, facilitating the movement operation of the device. Moreover, when the base 1 contacts the ground, the device can be more stable during use. At the same time, through the cooperation of the mounting column 323, the first mounting block 324, the support rod 325, the second chute 326, the second sliding rod 327, the second slider 328, the third spring 329, and the second mounting block 3210, when the device is jolted during movement, a buffering effect can be achieved.

[0045] Furthermore, the number of the support rods 325 is several, and they are grouped in pairs and symmetrically distributed on both sides of the mounting column 323.

[0046] When the device needs to be moved, the second hydraulic cylinder 322 drives the bottom plate 321 to move downward, so that the mounting column 323 can move downward synchronously, and then the moving wheels 3211 arranged at the bottom of the mounting column 323 can move downward synchronously. When the moving wheels 3211 move downward, due to the interaction of forces, the base 1 can be separated from the ground, and then the device can be moved manually. Moreover, when the device is jolted during movement, under the action of gravity, relative sliding can occur between the mounting column 323 and the bottom plate 321. Under the action of the first mounting block 324, the support rod 325, and the second mounting block 3210, the second slider 328 can move in the second chute 326 through the second sliding rod 327, deforming the third spring 329. Under the action of the elastic force of the third spring 329, a buffering effect can be achieved, thereby preventing damage to the centrifugal fan body 8 caused by jolts.

[0047] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
