[0021] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the following embodiments will specifically elaborate on the technical solutions of the present utility model in conjunction with the accompanying drawings.

[0022] Referring to Figure 1 , an embodiment of the present utility model provides a self-draining sealed hatch door for a deep-sea and far-sea floating body, which includes: a hatch door body 1, a water collecting tank 2, a contact water immersion sensor 3, a first water suction pipe 4, a first drain pipe 5, a first water pump 6, a liquid level switch 7, a second water suction pipe 8, a second drain pipe 9, an extended connecting pipe 10, a second water pump 11, a PLC electrical controller 12, and a sealing frame 13.

[0023] The first water pump 6, the second water pump 11, and the PLC electrical controller 12 are respectively fixed on the inner side surface of the hatch door body 1 through mounting seats and bolts. Referring to Figure 2 , the second water pump 11 is installed and fixed on the hatch door body 1 through a water pump mounting seat 11a and bolts, and the installation of the first water pump 6 is the same as that.

[0024] Referring to Figure 1 and Figure 2 , a sealing frame groove is provided on the inner side surface of the hatch door body 1, and the sealing frame 13 is installed in the sealing frame groove. The cross-section of the sealing frame 13 is in an L-shaped structure. The sealing frame 13 is made of rubber material, and the sealing frame 13 is used to play a sealing role between the door frame and the hatch door body when the hatch door is closed, so as to improve the tightness of the hatch door.

[0025] A water collecting tank 2 is arranged at the lower end part of the inner side surface of the hatch door body 1. When the floating body has a water inlet situation, the hatch door is used as a channel connecting to the outside world. Once there is a water inlet situation, the hatch door will be the first to be impacted by the water flow. Therefore, the water collecting tank 2 is set to collect water at the hatch door, and the water in the water collecting tank 2 is discharged in time to avoid flowing into the cabin body again, which can reduce the damage caused by the water flow entering the cabin body to a certain extent. In this embodiment, the sealing frame 13 and the water collecting tank 2 are of an integral structure.

[0026] Referring to Figure 3, a contact water immersion sensor 3 is arranged in the water collecting tank 2, and 3a in the figure is the signal transmission line of the contact water immersion sensor. The contact water immersion sensor is a highly sensitive sensor in the prior art for detecting whether water leakage occurs in the measured range. Its principle is based on the electrical conductivity of the liquid. Electrodes are used to detect the presence of water and then convert it into a dry contact to output an induction signal. It has two types of output states: normally open and normally closed. For the normally open type of contact water immersion sensor, it is in the conducting state without a medium and closes when there is a medium; for the normally closed type of contact water immersion sensor, it is in the closed state without a medium and conducts when there is a medium. In this embodiment, a normally closed contact water immersion sensor is adopted. The contact water immersion sensor 3 is electrically connected to the PLC electrical controller 12, and the PLC electrical controller 12 is electrically connected to the first water pump 6. When the water collecting tank is filled with water, the contact water immersion sensor 3 emits an induction signal, the circuit is conducted, and the PLC electrical controller 12 controls the first water pump 6 to start to suck the water in the water collecting tank.

[0027] Refer to Figure 1 and Figure 3 , the lower end of the first water suction pipe 4 extends into the water collecting tank 2, and the lower end part of the first water suction pipe 4 is a perforated pipe section 4a. The first water suction pipe 4 is used to suck the water in the water collecting tank 2. The upper end of the first water suction pipe 4 is connected to the water inlet of the first water pump 6. The first drain pipe 5 is connected to the water outlet of the first water pump 6 and the end of the first drain pipe 5 passes through the hatch body 1 and extends outwards. Its structure is the same as that of the second drain pipe 9, and reference can be made to Figure 2 the second drain pipe 9 in

[0028] The upper end of the second water suction pipe 8 is connected to the water inlet of the second water pump 11. The lower port 8a of the second water suction pipe 8 is located at the lower end position of the hatch. The extension connecting pipe 10 and the lower port of the second water suction pipe 8 are detachably connected. The extension connecting pipe 10 is a flexible pipe and is bolted to the lower port of the second water suction pipe 8 through a pipe joint (not shown in the figure). The length of the extension connecting pipe 10 is set according to actual needs, and the end of the extension connecting pipe 10 contacts the ground inside the cabin. The extension connecting pipe 10 and the second water suction pipe 8 are used to suck the water in the cabin. Refer to Fig. 2, the second drain pipe 9 is connected to the water outlet of the second water pump 11 and the end of the second drain pipe 9 passes through the hatch body 1 and extends outwards. The first drain pipe 5 has the same structure as the second drain pipe 9. A drain pipe port 16 is installed at the end of the drain pipe. The drain pipe port 16 is in the shape of an elbow as Figure 2 shown. In this way, the water discharged from the elbow-shaped drain pipe port has a certain lift and does not fall vertically, so the impact of the discharged water on the hatch is reduced.

[0029] Preferably, as Figure 1 shown, the second water suction pipe 8 is located on the side where the hinge 1a of the hatch body 1 is located. In this way, it will not affect the normal opening and closing of the hatch during normal times.

[0030] Refer toFigure 2 A sealing ring 19 is installed between the second drain pipe 9 and the hatch body 1, and a sealing ring is also installed between the first drain pipe 5 and the hatch body 1 to improve the sealing effect.

[0031] See also Figure 1 and Figure 5 , the liquid level switch 7 is arranged in the cabin 20, and 7a in the figure is the signal transmission line of the liquid level switch. The liquid level switch 7 is also called a water level switch, a liquid level sensor, and is a switch of the prior art that controls the on-off of a circuit by means of a liquid level. Its working modes include normally open and normally closed, and can be selected according to actual needs. In this embodiment, a normally closed liquid level switch is used, and the liquid level switch 7 is arranged at a specific position in the cabin, such as a position 0.5 cm from the cabin floor, to sense whether water has entered the cabin. The liquid level switch 7 is electrically connected to the PLC electrical controller 12, and the PLC electrical controller 12 is electrically connected to the second water pump 11. When water accumulates in the cabin, the liquid level switch 7 sends a sensing signal, the circuit is turned on, and the PLC electrical controller 12 controls the second water pump 11 to start and pump water into the cabin.

[0032] The first water pump 6 is used to absorb water from the water tank, and the water volume is small, and a low-power water pump can be used according to actual needs. The second water pump 11 is used to absorb water in the cabin body, and the water volume is large, and a high-power water pump can be used according to actual needs.

[0033] See also Figure 1 The first water suction pipe 4 is provided with a first check valve 14, and the flow direction of the first check valve 14 is to flow to the first water pump 6. The second water suction pipe 8 is provided with a second check valve 15, and the flow direction of the second check valve 15 is to flow to the second water pump 11. The one-way valve can prevent water from flowing back into the cabin.

[0034] The electrical components in the self-draining sealed hatch for deep-sea floating bodies of this embodiment are all powered by the power source of the floating body itself. Such floating bodies used for exploration, measurement, and logistics usually have batteries as power sources, and some are also equipped with solar power generation systems as supplementary power sources. Therefore, the self-draining sealed hatch for deep-sea floating bodies of the utility model does not need to be equipped with a separate power source, and can directly use the power source of the floating body.

[0035] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention are included in the protection scope of the present invention.
