Description

Technical Field

[0001] The present invention relates to the technical field of automatic cleaning of vehicle radiators, and more specifically, to an automatic cleaning system and method for an off-road vehicle radiator. Background Art

[0002] Military off-road engines generally use internal combustion engines. Part of the fuel used by the engine is converted into heat, so the engine needs to be cooled to ensure that it works at an appropriate temperature. The radiator is used to cool the engine. Due to their own characteristics, military off-road vehicles often travel in relatively harsh working conditions. The radiator is often covered with dust or adhered to debris, resulting in insufficient heat dissipation performance of the engine radiator, affecting the engine's power. Designing a device that automatically cleans the radiator can solve the problem of off-road vehicles easily clogging the radiator in complex environments.

[0003] The prior art has the following disadvantages: (1) When dust affects the heat dissipation performance of the radiator, it is generally necessary to disassemble it and manually flush it with a high-pressure water gun, which is time-consuming and cumbersome to operate; (2) When an automatic cleaning device is used, it is difficult to ensure the cleaning effect because the cleaning wind direction or sweeping action is fixed.

The two gear sets are used alternately to change the direction of power output from the conversion gear train to the mechanical fan, thereby achieving a better cleaning effect. Detergent solution is stored in the washing pot. Before the mechanical fan works, the detergent solution is pumped to the nozzle at the end through a water pipe by a water pump, and the high-pressure water flow is finally sprayed onto the radiator to wet and clean the dust thereon. The wind pressure sensor can detect the wind pressure near the radiator to help people in the vehicle determine whether the radiator is attached with too much dust and blocked, thereby solving the problems of poor vehicle radiator cleaning effect and inability to monitor radiator performance in real time.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0028] like Figure 1-Figure 3 As shown, the present invention provides an automatic cleaning system for an off-road vehicle radiator, comprising a radiator 1, a wind shield 2, a mechanical fan 3, an electromagnetic telescopic valve 13, a water pump 16, a wind pressure sensor 17 and a conversion gear train 20, wherein one end of the wind shield 2 is fixed to the radiator 1, and the mechanical fan 3 is fixed to the other end of the wind shield 2.

The fan 3 is connected in transmission to provide power for it. Since the cleaning effect of blowing air in a single direction is limited, the output direction of the conversion gear train 20 can be regulated by the electromagnetic telescopic valve 13, so as to realize the forward and reverse rotation of the mechanical fan 3 and better clean the radiator 1. In order to prevent the strong adhesion of stains, a water pump 16 and a wind pressure sensor 17 are also provided. The former is used to spray water to the radiator 1 to enhance the cleaning effect, and the wind pressure sensor 17 is used to sense the size of the wind pressure to realize the function of automatic monitoring, which solves the problems of poor cleaning effect of the vehicle radiator and inability to monitor the radiator performance in real time.
