Intelligent regulating type guard fence

Abstract

The invention discloses an intelligent regulating type guard fence. The intelligent regulating type guard fence comprises a front guard fence body, a radiator, a fan and an electronic control unit, and the electronic control unit is electrically connected with the radiator and the fan. The intelligent regulating type guard fenceis characterized in that the front guard fence body comprises a mounting plate with ventilation holes, and M air guide plates are hinged to one side of the mounting plate; and the M air guide plates are arranged in parallel, wherein M is a natural number larger than 1. The intelligent regulating type guard fence at leastfurther comprises a temperature sensor used for detecting the temperature information of an engine, connection rods chained to the air guide plates, a hydraulic oil cylinder used for driving the connection rods to act, and a magnetic valve set used for controlling the hydraulic cylinder to act, wherein the output terminal of the temperature sensor is electrically connected with the electronic control unit; and the magnetic valve set and the electronic control unit are electrically connected. By means of the intelligent regulating type guard fence, the problems that the air exhaust quantity of a prior engineering vehicle radiator cannot be adjusted as the opening degree of a front guard fence body cannot be actively regulated in real time along with the temperature changes of the engine, and sundries between the front guard fence body and the radiator cannot be removed in time are solved.

Description

technical field [0001] The invention relates to the technical field of engineering vehicles, in particular to an intelligently adjustable protective grille. Background technique [0002] At present, the heat generated by the engine of the engineering vehicle is dissipated by the radiator. Generally, a hydraulic motor is used to drive a fan to supply air to cool the radiator. The front end of the radiator, that is, the front of the machine, is equipped with a grille (the front grille mentioned below) to protect the radiator. There are generally two structures of the front grille: one is that the main body of the front grille is mostly a punching plate, which is generally an integrated punching plate, and the four corners of the punching plate are installed on the front end of the machine through bolts; The front grille adopts a welded structure, which is welded by a mounting plate and a row of horizontal wind deflectors with uniform spacing and a certain angle upwards, and ...

AI Technical Summary

Problems solved by technology

The intelligent adjustable grille can solve the shortcomings of the original engineering vehicle radiator air volume that cannot be adjusted in real time according to the engine temperature and the front grille opening can not be cleaned in time, and realizes safety and reliability. , saving energy, improving heat dissipation efficiency
