Detailed Description

The following detailed description of the embodiments of the present invention will be given in order to provide those skilled in the art with a more complete, accurate and thorough understanding of the inventive concept and technical solutions of the present invention.

As shown in fig. 1-3, the present invention provides an exhaust pipe for preventing wading, which comprises a two-section exhaust pipe 1, a shaft lever 2, an inner turbofan 3, a drainage screw 4, an outer turbofan 5, a connecting frame 6 and a one-way clutch 7, wherein the two-section exhaust pipe 1 comprises a front section pipe and a rear section pipe, the connecting frame 6 is rotatably connected between the front section pipe and the rear section pipe, the shaft lever 2 is coaxially connected with the connecting frame 6 through the one-way clutch 7, the inner turbofan 3 is coaxially fixed at the front end of the shaft lever 2, the drainage screw 4 is coaxially fixed at the rear end of the shaft lever 2, the outer side of the connecting frame 6 extends out of the two-section exhaust pipe 1, and the outer turbofan 5 is installed at the outer side of the connecting frame 6.

The outer side of the outer turbofan 5 is sleeved with a flow guide shell 8, and the flow guide shell 8 is coaxially fixed on the two-section exhaust pipe 1.

The front side of the guide shell 8 is fixed on the surface of the front section pipe, the rear side of the guide shell 8 is fixed on the surface of the rear section pipe, through holes are formed in the front side and the rear side of the guide shell 8, and the caliber of the front side of the guide shell 8 is larger than that of the rear side.

The drainage screw 4 includes a screw shaft coaxially fixed to the rear end of the shaft lever 2 and a helical blade spirally wound around the periphery of the screw shaft.

When the rotation speed of the outer turbofan 5 is greater than that of the inner turbofan 3, the one-way clutch 7 is in an engaged state, and when the rotation speed of the outer turbofan 5 is less than that of the inner turbofan 3, the one-way clutch 7 is in a disengaged state.

At first, two-section exhaust pipe 1 is arranged at the tail of automobile exhaust, inner turbofan 3 is arranged at the inner side of drainage screw rod 4, when the automobile runs forwards on a wading road surface, water flow passes through diversion shell 8 from front to back due to accumulated water on the road surface, a larger amount of water flow rushes into diversion shell 8 due to the large caliber at the front side of diversion shell 8, the water flow of outer turbofan 5 is pressed to be faster, water flow drives outer turbofan 5 to rotate and then flows out through a small opening at the rear side, outer turbofan 5 drives shaft rod 2 to rotate through connecting frame 6, shaft rod 2 drives drainage screw rod 4 to rotate for drainage work, meanwhile, the automobile exhaust can also provide thrust for inner turbofan 3, and the inner turbofan is driven to drain work in the same direction by water discharge screw rod 4.

When the car is traveling on normal road surface, when speed is slower, interior turbofan 3 is faster than outer turbofan 5 because the carminative reason of car self, because one-way clutch 7's setting this moment, outer turbofan 5 belongs to the state with axostylus axostyle 2 separation, outer turbofan 5 can not influence the carminative work of car self, when traveling at a high speed, outer turbofan 5 is faster in the lower speed ratio of effect of wind current, make outer turbofan 5 and axostylus axostyle 2 joint under one-way clutch 7's effect this moment, outer turbofan 5 drives interior turbofan 3 and rotates, promote the exhaust work of blast pipe.

The device can pass through outer turbofan 5, interior turbofan 3, link 6, axostylus axostyle 2, one way clutch 7 and drainage screw rod 4's cooperation work, make the car when the road surface traveles wading, can be driven by the outside rivers of two segmentation blast pipes 1 through outer turbofan 5, also can make drainage screw rod 4 carry out the discharge work to the inside water of intaking of two segmentation blast pipes 1 through interior turbofan 3 by the inside air current drive of two segmentation blast pipes, the effectual blast pipe that prevents the car is when wading too deeply, thereby the exhaust can't lead to flame-out problem emergence with ponding discharge blast pipe, both effectual vehicle safety of having protected, personnel's personal safety on the car has also been protected.

The invention is described above with reference to the accompanying drawings, it is obvious that the specific implementation of the invention is not limited by the above-mentioned manner, and it is within the scope of the invention to adopt various insubstantial modifications of the inventive concept and solution of the invention, or to apply the inventive concept and solution directly to other applications without modification.
