Abstract
The utility model discloses a water intake protection device of an engine. The water intake protection device comprises a water intake detection device, a master control chip, an engine flameout device, a resetting switch and a power supply module which are arranged in a tank of an air filter; the water intake detection device sends a detection signal to the master control chip, and the output end of the master control chip is connected with the engine flameout device; the resetting switch is connected with the master control chip; and the power supply module supplies power to the master control chip. The water intake protection device disclosed by the utility model is capable of effectively preventing a cylinder body from being broken due to water intake of the engine and reducing the economic loss and is reliable in water intake detection, simple and independent in structure and free of large change on an original vehicle.
Description
Technical field
The utility model relates to a kind of water inflow of the engine protective gear.
Background technique
If motor car engine water inlet; when valve-closing piston stroking upward pressurized gas, because not having compressibility, water can not cause valve to damage or cylinder rupture; add up annual Rain Storm of Mid-summer according to insurance company and attack the case that causes engine cylinder-body to break because of water inlet and reach several ten thousand, if when rainwater enters motor, can effectively detect and flame-outly rapidly can effectively protect motor.
The model utility content
The utility model purpose is to provide a kind of water inflow of the engine protective gear for the defective that prior art exists.
The utility model adopts following technological scheme for achieving the above object: a kind of water inflow of the engine protective gear comprises water inlet detecting device, main control chip, generator blanket, reset switch and power module in the case that is placed in air-strainer; Described water inlet detecting device sends to main control chip with testing signal, and the output terminal of main control chip connects the generator blanket; Reset switch is connected with main control chip; Power module is powered to main control chip.
Further, described water inlet detecting device comprises basin type container, and there is insulation board its top, the first probe and the second probe are installed on this insulation board, the first probe is from the power supply power taking, and the second probe is electrically connected with the voltage transitions chip, connects main control chip behind the voltage transitions chip.
Further, described first, second probe and basin type container interval 2CM, interval 5MM between two probes.
Further, described generator blanket comprises a bistable relay, and this relay is controlled by single-chip microcomputer and a bridge circuit output positive negative pulse stuffing.
The beneficial effects of the utility model: adopt this covering device can effectively prevent the cylinder block cracking that causes because of water inflow of the engine, reduce economic loss.Its water inlet detects reliable, simple in structure independent, need not former car is changed greatly.The engine misses control mode is simple, and safety is without hidden danger.
Description of drawings
Fig. 1 fundamental diagram of the present utility model;
Fig. 2 structural representation of the present utility model.
Embodiment
Fig. 1, shown in Figure 2 is a kind of water inflow of the engine protective gear, comprises water inlet detecting device, main control chip, generator blanket, reset switch and power module in the case that is placed in air-strainer; Described water inlet detecting device sends to main control chip with testing signal, and the output terminal of main control chip connects the generator blanket; Reset switch is connected with main control chip; Power module is powered to main control chip.
Wherein, the water inlet detecting device structure as shown in Figure 2, there is insulation board 2 basin type container 1 top, the first probe 1 and the second probe 2 are installed on the insulation board 2, the first probe 1 connects the voltage transitions chip from 12 volts of storage battery power takings behind the second probe 2, connects main control chip after the voltage transitions.
A whole set of water inlet detecting device can be placed in the case of air-strainer, when a large amount of rainwater enter suction port, in the current engagement type container 1, thereby conducting probe 1 and probe 2, convert the 12V electricity to 5V through the voltage transitions chip again, thereby to high level signal of main control chip input, receive the i.e. water inflow of the engine as can be known of this signal.
In implementation process, between probe and basin type container and the distance of being separated by between two probes certain requirement is arranged, general two probe spacings are from 5MM.Probe and basin type container 1 be apart from 2CM, so not only can guarantee the validity that detects but also can not report by mistake.
The engine misses controlling method is various.As control main power circuit or control the oil spout circuit.Also can in oil sprayer bonding circuit, be connected in series a bistable relay, a kind of be normal open a kind of be normally closed, this relay is controlled by single-chip microcomputer and bridge circuit output positive negative pulse stuffing.When receiving when needing locking information, thereby pulse of output changes relay into the Chang Kai line disconnection by normally closed, thereby so that motor is can't oil spout flame-out.
During work, inlet water sensor is transferred to main control chip with signal, and main control chip is judged according to the level signal that receives, and exports immediately control command to engine misses control mechanism and rapidly execution.Need manually dewater after the water inlet, and main control chip resetted get final product.
The above only is preferred embodiment of the present utility model, and is in order to limit the utility model, not all within spirit of the present utility model and principle, any modification of doing, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
