Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-2, the present invention provides a technical solution: a novel marine water supply and drainage device comprises a water collection box 1, an electric drainage pump 2, a water outlet pipeline 3, a water inlet pipeline 4 and a power supply 6, wherein a float switch 5 is arranged inside the water collection box 1, the float switch 5, the electric drainage pump 2 and the power supply 6 form a loop, the electric drainage pump 2 is connected in parallel with a relay 7 and a time relay normally closed contact 8 which are connected in series in the loop, the time relay normally closed contact 8 is reset after being switched on for a set time, the electric drainage pump 2 is also connected in parallel with a time relay 9 in the loop, the float switch 5 is connected in parallel with a relay normally open contact 10 in the loop, the relay normally open contact 10 is closed after being switched on and is reset after being switched off, and the device can select 12V or 24V electric mode according to, the delay time of the time relay 9 is calculated according to the capacity of the water collecting and draining device and the flow of the electric draining pump 2, so that the water collecting and draining requirements of most ships under most conditions are met.

Specifically, as shown in fig. 1, the water outlet pipeline 3 is connected to the electric drainage pump 2 and is installed at the bottom end of the water collecting box 1, and the sewage is discharged through the electric drainage pump 2 and the water outlet pipeline 3.

Specifically, as shown in fig. 1, the float switch 5 is installed on the top side wall of the interior of the water collecting box 1, and if the float switch 5 is installed on the bottom of the water collecting box 1, the electric drain pump 2 operates as long as a small amount of sewage is accumulated in the water collecting box 1, which may cause frequent activation of the electric drain pump 2.
