Description

Technical field:

[0001] The invention relates to the technical field of outdoor fan installation, and more particularly to an installation method and a workbench for a large column-type fan. Background technology:

[0002] In early spring and late autumn, the temperature drops due to the invasion of cold air, especially in clear and windless nights and early mornings. The radiation heat dissipation of some hillsides increases, and the ground temperature drops rapidly. At the same time, the plants planted on the ground, such as trees and tea trees, also cool down rapidly. When the surface temperature of the plants drops below 0℃, they will suffer from frost damage. If the tree is damaged by frost, the quality and yield of the fruit produced by the fruit trees will be affected. For example, frost damage to tea trees directly causes the tea leaves to freeze and wither, seriously affecting the yield of tea. Therefore, fans are installed above the plants through columns to prevent freezing by transporting the higher temperature air from high places to the ground. This type of fan is called a frost-proof fan.

[0003] There are many kinds of frost-proof fans on the market. The structure of one of them is shown in the figure attached to the instruction manual. Fig. 9 Therefore, a fan with large blades is fixedly installed on the top of the column 2. The fan expands the frost-proofing range based on the large blades, but the installation of the fan is relatively difficult because the areas where the fan is used are mostly mountainous terrains, and vehicles such as cranes and lifting trolleys cannot reach the installation area, that is, the fan cannot be hoisted by cranes, lifting trolleys, etc.; therefore, it is necessary to design a method for convenient installation of the frost-proof fan. Summary of the invention:

[0004] The purpose of the present invention is to address the deficiencies of the prior art and to provide an installation method and workbench for a large column-type fan. The designed workbench and hoisting method can facilitate the installation of an outdoor large column-type anti-frost fan.

[0005] A method for installing a large column-type fan, the installation method comprising the following steps:

[0006] ①. Set up the column. The installer will plug and fix the column on the ground where the large fan is to be installed. There are several linearly distributed sockets on the column.

[0007] ② Install the pedal. The installer inserts several iron bars into the sockets of the column from bottom to top. Both ends of the iron bars extend out of the column to be used as pedals.
