Embodiment 2

[0033] Embodiment 2 is different from Embodiment 1 in that, since there are some debris inside the tower that is easy to fall off, such as structural rubber blocks, if it enters the axial flow fan 5, it will seriously threaten the safe operation of the axial flow fan 5, and even Cause the axial flow fan 5 to shut down, and then cause other problems. In order to ensure the safe operation of the axial flow fan 5, a layer of heavy steel mesh 9 is installed on the underside of the bracket mounting flange 8, and a layer of ventilation steel mesh 10 is installed on the lower surface of the heavy steel mesh 9, and the bracket mounting flange 8 and The heavy steel mesh 9 is welded together to form a platform protection plate, which is used for safety protection, and the ventilation steel mesh 10 is used to prevent falling small parts from entering the axial flow fan 5 and causing danger.

Embodiment 3

[0034] The third embodiment is different from the above-mentioned embodiments in that, since the axial flow fan 5 has certain vibrations during operation, in order to reduce the impact of the vibration on the wind power generator, the axial flow fan 4 is installed with the flange 4 and the axial flow fan. A flange damping element 3 is arranged between the upper mounting surface of the fan 5 and / or between the lower mounting flange 1 of the axial flow fan and the lower mounting surface of the axial flow fan 5 to absorb and buffer the vibration of the axial flow fan 5; A platform damping element 7 is installed between the fixed support 2 and the bracket mounting flange 8 and / or between the short fixed support 6 and the bracket mounting flange 8 to further buffer the vibration of the axial flow fan 5 .

Embodiment 4

[0035] Embodiment 4. This embodiment provides a method for using and installing the above-mentioned installation bracket of the tower platform axial flow fan. The installation bracket is suspended and installed on the tower platform by using platform welding bolts, and then the axial flow fan is suspended and installed on the tower. Below the platform, including the following key steps:

[0036] Step 1. Pass the platform welding bolts from the lower side of the tower platform to the upper surface, and then weld the lower end of the platform welding bolts to the lower side of the tower platform, so that the platform welding bolts will not fall off and can be carried out from above the tower platform. The locking and dismounting of the fastening nut facilitates the installation and disassembly of the mounting bracket.

[0037] Step 2. Attach the flange damping element to the mounting flange under the axial fan of the large bracket, and then install the lower mounting surface of ...

Abstract

The invention discloses an installation bracket for an axial flow fan of a tower barrel platform. The installation bracket comprises a large bracket, a small bracket and a bracket installation flange, wherein the axial flow fan is fixedly installed between the large bracket and the small bracket; the large bracket and the small bracket are fixedly connected with the bracket installation flange respectively; the bracket installation flange is fixedly connected to the upper surface of the tower barrel platform; the large bracket and the small bracket penetrate through inner holes of the tower barrel platform. The installation bracket is reliably suspended on the lower side of the tower barrel platform, and the axial flow fan is further reliably suspended on the lower side of the tower barrel platform. All positioning and installation holes are U-shaped installation holes and can be assembled and disassembled one by one during the installation of the platform, and the installation and maintainability of the axial flow fan are improved. By the adoption of an installation flange and a fixed support, which are similarly structured, the installation bracket is simple and firm in structure; a heavy steel plate screen is arranged above the bracket and is used for safety protection; an air ventilation steel wire screen is arranged below the steel plate screen and is used for preventing small parts from falling down into the axial flow fan so as to avoid a danger.

Description

technical field [0001] The invention relates to a mounting bracket and a method for using and installing the mounting bracket of an axial flow fan applied to a wind power generator, in particular to a mounting bracket for an axial flow fan in a tower air-cooled heat dissipation system and a method for using and installing the mounting bracket. Background technique [0002] With the increase of the rated power of the wind turbine, a large amount of heat is generated on the surface of electrical components such as inverters and reactors inside the tower. In order to accelerate the heat dissipation, the tower platform needs to be installed with an axial flow fan for auxiliary heat dissipation. Generally, the axial flow fan is installed above the tower platform. This installation method takes up a lot of working space on the tower platform and brings great inconvenience to the installation, use and maintenance of other equipment. Therefore, the axial flow fan is installed on the ...
