Problems solved by technology

[0002] At present, construction vehicles are generally used in places with relatively harsh environments. Condensing fans are used to blow and dissipate heat from the condenser core on construction machinery air conditioners. If it is blocked, it will affect the heat dissipation of the condenser, and even cause damage to the equipment.
At present, regular manual cleaning is generally used to remove weeds and dust accumulated over a long period of use. This is not conducive to improving efficiency, and it is also inconvenient to remove weeds inside the device.

Abstract

The invention discloses an electromechanical device, and particularly relates to a device, used on a vehicle, of adjusting forward and reverse rotation of a condensing fan. The device comprises relays, a switch and a fan, wherein the relays comprise a time relay KJ1 and two relays KJ2 and JK3; a switch and the like are arranged in each relay; one of the two relays KJ2 and KJ3 is normally open and the other one of the two relays KJ2 and KJ3 is normally closed; and the forward and reverse rotation time is adjusted through time setting of the time relay JK1 to control the action of the fan. The device has the advantages of improving the radiating effect of a condenser and reducing the manual cleaning frequency. By using the condensing fan with excellent blowing and air suction effects and through control circuit design, forward and reverse rotation control of the condensing fan is realized to blow weeds and dust out. The device can be widely applied to mechanical vehicles operating outdoors.

Description

technical field [0001] The invention relates to an electromechanical device, in particular to a device for adjusting forward and reverse rotation of a condensing fan on a vehicle. Background technique [0002] At present, construction vehicles are generally used in places with relatively harsh environments. Condensing fans are used to blow and dissipate heat from the condenser core on construction machinery air conditioners. If it is blocked, it will affect the heat dissipation of the condenser, and even cause damage to the equipment. At present, regular manual cleaning is generally used to remove weeds and dust accumulated over a long period of use. This is not conducive to improving efficiency, and it is also inconvenient to remove weeds inside the device. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the invention proposes a device that is easy to operate and safe to use. [0004] The present invention is achieved through the followin...
