Drainage device for cabin of yacht

[0020] In order to better understand the improvements made by the present invention over the prior art, the specific implementations are described in detail below. figure 1 Shows a schematic structural diagram of a yacht cabin drainage device. The inlet and outlet pipes connected to the inlet and outlet ends of the solenoid valve 1, and the suction pipe 4 connected to the water pipe at one end but smaller in diameter than the outlet pipe. One end of the water pipe leads to the water inlet 51 on the tank floor, and one end of the water pipe leads to The bilge water outlet 61 on the stern seal plate; the suction pipe 4 leads to the bilge water, the cabin drainage device also includes a drainage structure 12, and the cabin drainage device includes a ventilation steel pipe 121 arranged on one side of the water pipe 20, and the ventilation steel pipe 121 faces away The direction of the water outlet is obliquely arranged on one side of the water pipe 20. One end of the ventilation steel pipe 121 away from the drain pipe is provided with an external thread, the compressed air joint 123 is provided with an internal thread matching the external thread, and the joint between the ventilation steel pipe 121 and the compressed air joint 124 is provided with an air leakage prevention device 123, The ventilation steel pipe 121 and the compressed air joint 123 are fixedly connected by bolts. As a preferred solution of the cabin drainage device, the included angle between the ventilating steel pipe 121 and the drain pipe 20 is 15°~45°, and the included angle between the ventilating steel pipe 121 and the drain pipe 20 is 28°. When the switch is turned on, the force that enters the drain pipe to absorb water through the hose and the water absorption assembly is the greatest, and the water absorption speed is also fast, that is, the accumulation of water discharged from the water outlet is the fastest.

[0021] The cabin drainage device also includes a control box, which is respectively connected with the solenoid valve and the alarm;

[0022] When the water level rises to the position that triggers the high level sensor, the drain solenoid valve opens, and the water is discharged under the action of gas pressure, and the water level drops continuously. When the water level drops to the low level sensor, the drain solenoid valve Shut down and stop water discharge.

[0023] The control box is equipped with a wireless module, which is connected to the remote terminal through WIFI.

[0024] In the improvement scheme of the above-mentioned yacht cabin drainage device, the bilge water outlet is 310-380mm above the waterline in height.

[0025] figure 2 show figure 1 Shows the schematic diagram of the structure of the anti-leak device 122. The connection between the ventilating steel pipe 121 and the compressed air joint 124 is fixedly connected by the anti-leak device 122. The anti-leak device is provided with a rubber sealing ring 1221, so that better and more reliable The shaft sealing effect can achieve a good and stable shaft sealing.

[0026] Compared with the prior art, the drainage structure is controlled to communicate with the water pipe through a control box, and the drainage structure is provided with a ventilation steel pipe 121 for compressed air injection and a compressed air joint 123, and the ventilation steel pipe 121 is inclined toward the end away from the water outlet. The force of compressed air can be used to suck the water in the bilge of the yacht through the water pipe, that is, compressed air is injected into the drainage structure toward the water outlet, causing the pressure in the drainage pipe of the drainage structure to be lower than the pressure in the ship section. Generates water-absorbing suction, sucks the water in the bilge of the yacht into the hose, and automatically adjusts it through the control box. When the water level rises to the position where the high level sensor is triggered, the drain solenoid valve opens and the water is discharged under the action of gas pressure. The level of water drops continuously. When the level of water drops to the low level sensor, the drain solenoid valve is closed and the water discharge stops. The entire drainage process is reliable, which is conducive to the safety of the front and rear equipment, changes the uncertainty of the previous manual drainage, eliminates the damage to the air compressor and dryer caused by the failure of water to be discharged in time, improves the quality of compressed air, makes the water discharged in time, and reduces the follow-up The load of the dryer and the filter is beneficial to improve the quality of compressed air, and the operation is convenient. The water level information and alarm information can be viewed in real time through the remote terminal.

[0027] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above-mentioned embodiments. Within the scope of knowledge possessed by a person of ordinary skill in the art, various modifications can be made without departing from the purpose of the invention. Kind of change.
