Description

TECHNICAL FIELD

[0001] The present application relates to the field of ocean exploration technology, in particular to an underwater automatic control system for ship ocean exploration operation. BACKGROUND

[0002] In the prior underwater automatic control system for ship ocean exploration operation, mechanical limit switches are used for opening the watertight door and retracting the probe. When the contact rod of the mechanical limit switch contacts or separates from the watertight door, the contact rod retracts or extends, causing the contact to close or open, and giving the corresponding automatic control signal. In the ship body, underwater, and compressed air cabin, there is a lot of water vapor, and the air pressure in the cabin changes frequently as the automatic operation proceeds. The water vapor can penetrate into the box body of the limit switch through the seal as the contact rod of the mechanical limit switch retracts and extends, causing the contact of the limit switch in the box body to short circuit, and causing the automatic control system to fail. After such a failure, the hydraulic system may be misoperated to crush the multibeam echo sounder, or the hydraulic equipment may be damaged. After the failure, a hand pump needs to be used to replace the electric hydraulic pump, which is laborious. CONTENT OF THE UTILITY MODEL

[0014] The utility model will be further described below with reference to the drawings, and it is to be noted that the embodiment is based on the technical scheme, and detailed implementation and specific operation process are given, but the protection scope of the utility model is not limited to the embodiment.

[0015] The embodiment provides a kind of underwater automatic control system for marine detection operation of ship, as shown in Figure 1 It is shown that including probe telescopic hydraulic cylinder 100, inner opening water-tight door hydraulic cylinder one 101 and inner opening water-tight door hydraulic cylinder two 103, the probe telescopic hydraulic cylinder 100 is connected to electromagnetic valve one 141 by hydraulic line, and inner opening water-tight door hydraulic cylinder one 101 and inner opening water-tight door hydraulic cylinder two 103 are respectively connected to electromagnetic valve two 142 by hydraulic line, and the electromagnetic valve one 141 and electromagnetic valve two 142 are respectively connected to the connecting pipe line of hydraulic power station 102 by hydraulic line;Inner opening water-tight door hydraulic cylinder one 101 and inner opening water-tight door hydraulic cylinder two 103 are connected to inner opening water-tight door respectively, and are used to drive inner opening water-tight door to open or close;The multi-beam depth finder is located at the bottom of probe telescopic water-tight door, and the probe telescopic hydraulic cylinder 100 is connected to probe telescopic water-tight door and is used to drive probe telescopic water-tight door to open or close;Inner opening water-tight door and probe telescopic water-tight door are respectively arranged at the side and directly above the opening of underwater airtight cabin;

[0018] In normal state, the underwater closed cabin is filled with compressed air, and the inner opening water-tight door is closed on the opening of the underwater closed cabin.

If the control system receives the signal of the two magnetic induction switches of the water-tight door opening limit switch 173, the control system starts the hydraulic power station and the electromagnetic valve one 141 at this time, controls the probe retracting water-tight door to close through the probe retracting hydraulic cylinder, and the multi-beam probe is extended into the water along with the closing of the probe retracting water-tight door. At this time, the marine surveying operation can be started. If the control system only receives the signal of one magnetic induction switch of the water-tight door opening limit switch 173, it is a false induction and no action is needed.

If the control system receives the signal of the two magnetic induction switches of the probe retracting limit switch 171, it is confirmed that the probe retracting water-tight door is opened.

Similarly, if the control system only receives the signal of one magnetic induction switch of the probe retracting limit switch 171, it is a false induction and no action is needed.
