Intelligent driving device for fan of cooling tower

Abstract

The invention discloses an intelligent driving device for a fan of a cooling tower, which comprises a ratchet mechanism (1), the fan (2), a hydraulic turbine (3), a motor (4) and an intelligent controller (5). A hub of the fan (2) is fixed with an outer wheel of the ratchet mechanism (1) in a horizontal direction; an output shaft of the hydraulic turbine (3) is connected with the ratchet mechanism (1) through a coupler; and the output shaft of the motor (4) is connected with the ratchet mechanism (1) by an axle hole. Under the condition that a load is not very high or the environment is not very severe, the cooling tower needs a relatively low blowing rate and the hydraulic turbine (3) independently drives the fan (2) to run through the output shaft (35) and an outer ring (101) of a ratchet. Under the condition that the load is relatively high or the environment is relatively severe, the cooling tower needs a relatively high blowing rate, and the motor (4) runs under the control of the intelligent controller (5), and drives the fan (2) to run with the hydraulic turbine (3) through the transmission of the ratchet mechanism (1) so as to provide enough blowing rate for normal runningof the cooling tower.

Description

technical field [0001] The invention relates to an intelligent driving device for a cooling tower fan, in particular to a high-efficiency and energy-saving cooling tower fan intelligent driving device based on hybrid driving and intelligent control of electric energy and mechanical energy. Background technique [0002] The cooling tower is a very common water resource recycling equipment at present. Its main function is to exchange heat between the cooling water containing waste heat and the air in the tower and to treat the water with medicine so that it can reach the required temperature and water quality for reuse. cycle. Due to the need for heat dissipation, powerful cooling fans are installed in cooling towers. At present, most of the cooling fans used in cooling towers are driven by electric motors with corresponding reduction mechanisms, which consume a lot of electric energy; on the other hand, Most of the cooling towers that are actually used at present, the circul...

Problems solved by technology

[0006] The purpose of the present invention is to solve the problems that the reliability of the existing cooling tower is reduced due to the simple application of the water turbine to drive the fan, the popularization and application are restricted, and the working state of the cooling tower itself is single, and energy-saving operation cannot be realized.
