Detailed description of the invention
Fig. 1 is the schematic diagram of structure of the present invention.
In figure: exhaust pipe 1, exhaust valve 2, engine 3, air inlet pipe 4, air inlet pipe valve 5, sealing ring 6, early warning water level
Sensor 7 closes water level sensor 8, float cylinder 9, water tank 10, water pump 11, gear 12, rack gear 13, float 14, water-break water level biography
Sensor 15, water inlet 16, ECM 17.
Specific embodiment
Present invention is further described in detail with specific embodiment with reference to the accompanying drawing:
As shown in Figure 1, a kind of automobile wading or park waterlogging when avoid automatically cylinder intake device, including hair
Motivation 3, float cylinder 9 and ECM 17, it is characterised in that: the 3 upper end two sides of engine are respectively equipped with exhaust pipe 1 and air inlet pipe 4,
The exhaust pipe 1 is equipped with exhaust valve 2, and the air inlet pipe 4 is equipped with air inlet pipe valve 5, is cased on the float cylinder 9 close
Seal 6 is simultaneously slidably connected with it, and 6 lower section of sealing ring is equipped with water inlet 16 on float cylinder 9, and 6 side of sealing ring is solid
Surely there is rack gear 13, the rack gear 13 is engaged with the gear 12 being fixed on stepper motor output shaft, and 9 side of float cylinder is under
It is successively arranged water-break water level sensor 15, early warning water level sensor 7 on and and closes water level sensor 8, the early warning water level passes
Above sealing ring 6, the water-break water level sensor 15 is described floating below water inlet 16 for sensor 7 and closing water level sensor 8
9 lower inside of auxiliary cylinder is equipped with float 14, and 9 lower end of float cylinder is connect by water pipe with water pump 11, the water pump 11 and water tank
10 connections, the exhaust valve 2, air inlet pipe valve 5, stepper motor and water pump 11 are controlled by ECM 17 respectively, described pre-
Alert water level sensor 7, closing water level sensor 8 and water-break water level sensor 15 are electrically connected with ECM 17 respectively.
The height of the sealing ring 6 is greater than the height of water inlet 16.
The diameter of the water pipe is less than the diameter of float cylinder 9.
The exhaust valve 2, air inlet pipe valve 5, stepper motor and water pump 11 are electrically connected with external power supply respectively.
The diameter of the float 14 is less than the diameter of float cylinder 9.
The water tank 10 is equipped with water filling port and water outlet.
Working principle: when driver, which starts engine, goes out vehicle, the present apparatus starts self-test.17 order stepper motor of ECM
The gear 12 of (not shown) driving rotates, and band carry-over bar 13 moves down, and makes sealing ring 6 that water inlet 16 be fully sealed.Then 17 ECM
The water that order water pump 11 extracts in water tank 10 enters float cylinder 9, increase the water level in float cylinder 9.It is closed when float 14 reaches
When the height of water level sensor 8, closes water level sensor 8 and successfully ordered to the transmission self-test of ECM 17.
After present apparatus self-test success, the water in float cylinder 9 is drawn back water tank 10 by 17 order water pump 11 of ECM.When water-break water level
When sensor 15 detects float 14, the gear 12 of 17 order stepper motor (not shown) of ECM driving is rotated, band carry-over bar 13
It moves up, fully opens water inlet 16, whether this state can detect automobile at any time and paddle or park waterlogging.
If self-test is unsuccessful, driver is prompted to need repairing the present apparatus.
If automobile wading or park waterlogging when, water level is possible to be increased to the height of damage engine.When entrance float cylinder 9
In water level make float 14 be more than early warning water level sensor 7 height and do not reach close water level sensor 8 height when, ECM
17 can prompt driver to paddle with caution.
When the water level entered in float cylinder 9 makes float 14 reach the height for closing water level sensor 8, the order row of ECM 17
Tracheae valve 2 and air inlet pipe valve 5 generate closing motion and remain off simultaneously.
When the water level entered in float cylinder 9 makes float 14 return to the height of water-break water level sensor 15, ECM 17 is ordered
It enables exhaust valve 2 and air inlet pipe valve 5 while generating breakdown action and keeping it turned on, engine 3 is in normal exhaust
And air-suction state.
