Embodiment 1

[0017] Such as Figure 1 to Figure 3 As shown, a kind of anti-water alarm protection device for automobile engine air intake pipe includes a water inlet detection device and an alarm protection circuit 7. The float 4 that descends and moves up and down, the fixed electrode located on the inside top of the float chamber 3, the floating electrode 21 located on the top of the float 4 and capable of electrical contact with the fixed electrode, the water inlet 5 located at the lower part of the side wall of the float chamber 3 and Located on the exhaust port 17 on the upper part of the side wall of the float chamber 3, the alarm protection circuit 7 includes an alarm device connected to the fixed electrode and an engine control circuit 23 connected to the alarm device.

[0018] The outer side of the float chamber 3 is also provided with a layer of casing 15, and the casing 15 is fixed below the intake pipe of the automobile engine through the fixing hole 1. The alarm device includ...

Embodiment 2

[0023] In order to reflect the different distances between the road water and the engine intake pipe, to remind the driver of the road conditions and accurately control the speed of the vehicle or turn off the engine to stop, this embodiment proposes another structure, such as image 3 As shown, the automobile engine intake pipe anti-water alarm protection device includes multi-stage water ingress detection devices connected in sequence along the vertical direction of the horizontal plane, multi-level alarm devices connected to the water ingress detection devices correspondingly, and the highest level of alarm devices. The engine control circuit, wherein each level of water inlet detection device and alarm device are all identical with the structure of embodiment 1.

[0024] Now take the three-stage water inflow detection device and alarm device as an example to illustrate, wherein, the electrode 11 of the float chamber 12 of the first-stage water inflow detection device is con...

Abstract

The invention discloses an alarm and protection system for preventing water induction in an intake tube of an automobile engine, comprising a water induction detection device and an alarm and protection circuit (7). The water induction detection device comprises a floater chamber (3), a floater (4) which is arranged in the floater chamber (3) and vertically moves with the rising and lowering of water level, a fixed electrode which is arranged at the top part of the interior of the floater chamber (3), a floating electrode (21) which is arranged at the top part of the floater (4) and can be in electric contact with the fixed electrode, a water inlet (5) arranged at the lower part of the side wall of the floater chamber (3) and an air outlet which is arranged at the upper part of the side wall of the floater chamber (3). The alarm and protection circuit (7) comprises an alarm device which is connected with the fixed electrode and an engine control circuit (23) which is connected with the alarm device. The alarm and protection system of the invention has superior performance, quick response, reliability, simple structure and comparatively low cost.

Description

technical field [0001] The invention relates to an alarm protection device, in particular to an alarm protection device for preventing water ingress into an automobile engine intake pipe. Background technique [0002] In the rainy season, the road is prone to water accumulation. When the car passes the waterlogged section, it is difficult for the driver to accurately estimate the depth of the water accumulation on the road and the relative position of the engine air intake. damage. For this reason, people in the industry have tried every means to conduct research in this area, but no relevant research results have been seen so far. Contents of the invention [0003] Aiming at the disadvantages of the prior art, the purpose of the present invention is to provide a kind of anti-water alarm protection device for automobile engine intake pipe which can prompt the driver to pay attention in time according to the different distances between the accumulated water and the engine ...
