Water level detection and automatic water discharging system of engine compartment direct-current electric pump for power surfboard

Abstract

The invention relates to a water discharging system of a power surfboard or a motorboat, in particular to a water level detection and automatic water discharging system of an engine compartment direct-current electric pump for the power surfboard. The water level detection and automatic water discharging system comprises a water discharging pipe, wherein a water inlet of the water discharging pipe is formed in a soleplate on the inner tail part of an engine compartment, and a water outlet of the water discharging pipe runs out of an engine compartment water discharging opening located in a top panel of a floating plate body; the water discharging pipe is provided with an engine compartment water discharging filter and a direct-current electric water discharging pump, a water level detector is arranged on the soleplate on the inner tail part of the engine compartment, both the direct-current electric water discharging pump and the water level detector are communicated with a controller, with a single chip microcomputer, of a control system through a conducting wire, the water level detector feeds a detection signal back to the controller with the single chip microcomputer, and the controller with the single chip microcomputer controls the direct-current electric water discharging pump to run automatically. By adopting the structure, the back flowing of water is avoided, no accumulated water in the engine compartment is guaranteed, and the application performance is improved.

Description

technical field [0001] The invention relates to a drainage system for a power surfboard or a motorboat, in particular to an automatic drainage system for detecting the water level of a direct current electric pump in an engine compartment of a power surfboard, which avoids backflow of water, ensures no accumulation of water in the engine compartment, and improves usability. Background technique [0002] Surfing is popular for its thrills and effective physical exercise. Ordinary surfboards must borrow the thrust of wind and waves before they can be used. When there is no wind and waves or the wind and waves are small, the surfboard will lose its due utility. In order to realize surfing without wind waves or when the wind waves are small, a kind of power surfboard in the prior art uses an engine as power, which can surf on the sea surface or drive on a calm water surface; this type of power surfboard generally Including the hull assembly, power unit, joystick, main empennage...

AI Technical Summary

Problems solved by technology

[0003] Portable power surfboards and ultra-light motorboats are completely submerged in the engine compartment during the process of starting, low speed, and deceleration braking. It is inevitable that water will enter the engine compartment, especially in the past negative pressure drainage system, water will flow from the drain pipe A large number of roads enter the engine compartment, which will seriously affect the normal operation of the engine, and will also increase the weight of the hull, resulting in slower speed increase. The flow of water in the cabin will cause the hull to become unstable and difficult to control.

[0004] To sum up, in the negative pressure drainage system of the prior art, water will flow back into the engine compartment from the drain pipe, and the accumulated water will seriously affect the normal operation and use effect of the engine.
