Description

Technical Field

[0001] The utility model relates to the technical field of water ingress alarm and drainage in a multi-beam probe cabin of a surveying and mapping vessel, and in particular to a control device for graded water ingress alarm and processing in a multi-beam probe cabin. Background Art

[0002] In existing surveying vessel multi-beam probe retraction and deployment control systems, if water ingress into the multi-beam probe compartment occurs, on-duty personnel must detect it through the multi-beam probe compartment monitoring system and the control box's optical alarm. Furthermore, draining the multi-beam probe compartment must be performed manually. Therefore, during periods of downtime, at night when crew members are resting, or when the survey room is unattended, crew members may not be able to detect a leak in time. Furthermore, the existing control system lacks robust automated response measures, potentially threatening the safety of electrical components within the multi-beam probe compartment and potentially causing serious damage to surveying and mapping operations.

[0014] The present invention will be further described below in conjunction with the accompanying drawings. It should be noted that this embodiment is based on the technical solution and provides a detailed implementation method and specific operation process, but the protection scope of the present invention is not limited to this embodiment.

[0015] This embodiment provides a multi-beam probe cabin water ingress classification alarm and processing control device, such as Figure 1 As shown, it includes a float switch 1, a float switch 2, a float switch 3, a warning light 1, a buzzer 5, a drain pump 2, a drain solenoid valve 3, a pressure relay, an extension alarm 6, a time relay 1KT, an intermediate contactor 1KA, an inflation solenoid valve 7, a relay 1KM, a relay 2KM, a relay 3KM and a relay 4KM; the warning light 1, the drain pump 2, the drain solenoid valve 3, the buzzer 5, the extension alarm 6 and the inflation solenoid valve 7 are connected in parallel and are all connected to the power switch QS;

[0016] Float switch 1, float switch 2, and float switch 3 are respectively used to measure different water level heights, and the water level heights measured by float switch 1, float switch 2, and float switch 3 increase in sequence;

[0017] The warning light 1 is connected in series with the contact 1K1 of the float switch 1; the drainage pump 2 is connected in series with the contact 2K2 of the float switch 2; the drainage solenoid valve 3 is connected in series with the contact 3K3 of the float switch 2; the contact 1K1 of the float switch 2, the coil of the relay 1KM and the buzzer 5 are connected in series, the contact 1KM1 of the relay 1KM and the contact 1K1 of the float switch 2 are connected in parallel; the contact 3K1 of the float switch 3 is connected to the coil of the relay 2KM and the coil of the relay 3KM respectively, the coil of the relay 2KM is connected in series with the extension alarm 6, the coil of the relay 3KM is connected to the time relay 1 KT is connected in series; the contact 2KM1 of the relay two 2KM is connected in series with the time relay 1KT, and the contact 3KM1 of the relay three 3KM is connected in series with the inflation solenoid valve 7; the contact 1KT1 of the time relay 1KT is connected in series with the coil of the intermediate contactor 1KA, and the contact 1KA1 of the intermediate contactor 1KA is connected in series with the air compressor; the two ends of the coil of the relay four 4KM are respectively connected in series with the normally open contact PL and the normally closed contact PH of the pressure relay, and the contact two 4KM2 of the relay four 4KM is connected in series with the inflation solenoid valve 7; the contact one 4KM1 of the relay four 4KM is connected in parallel with the normally open contact PL of the pressure relay.

[0018] In this embodiment, the buzzer 5 is connected in series with a self-locking button SB1. After the buzzer is powered on, the staff can press the self-locking button SB1 to disconnect the power supply of the buzzer and manually confirm and silence the alarm.

[0019] In this embodiment, the extension alarm 6 is connected in series with a second self-locking button SB2. Similarly, after the extension alarm is powered on, the staff can press the second self-locking button SB2 to disconnect the power supply of the extension alarm and manually confirm and silence the alarm.

[0020] The working principle of the above control device is:

[0021] When water enters the multibeam probe compartment or residual water reaches the critical water level x during the ship's swaying, a level 1 alarm is triggered, serving as a warning (a level 1 alarm helps to attract the attention of personnel). When the water level reaches height x, the float switch actuates, its contact 1K1 closes, and the warning light is energized, providing real-time feedback on the water level in the multibeam probe compartment.

[0022] When the water level rises to y, float switch 2 activates. Contact 1 (2K1) of float switch 2 closes, energizing the coil of relay 1KM. Contact 1KM1 of relay 1KM closes and self-locks, energizing the buzzer. Furthermore, contacts 2K2 and 2K3 of float switch 2 close, energizing drain pump 2 and opening drain solenoid valve 3, which opens and connects to the drainage pipe. A manager can press self-locking button SB1 to acknowledge the alarm and silence buzzer 5 without affecting the drainage operation of drain pump 2 and drain solenoid valve 3.

[0023] When the multi-beam probe cabin takes on a large amount of water and no one responds, the water level continues to rise until z, and the float switch three is actuated, wherein the contact 3K1 of the float switch three is closed, the coils of relay two 2KM and relay three 3KM are energized, and the contact 2KM1 of relay two 2KM is closed and self-locked. At this time, the extended alarm 6 (installed in the crew's cabin) is energized and sounds an audible alarm (this is a level three alarm) to alert the crew. At the same time, the contact 3KM1 of relay three 3KM is closed, connecting the inflation solenoid valve circuit, and the inflation solenoid valve 7 is energized and opened, connecting the inflation pipeline, and preparing for the inflation of the multi-beam probe cabin. In addition, the time relay 1KT is energized, and the contact 1KT1 is delayed in closing, so that the intermediate contactor 1KA is delayed in energizing, and the contact 1KA1 of the intermediate contactor 1KA is closed, connecting the power supply of the air compressor (the air compressor is set to the automatic control position by default, Figure 1 (QF represents the air compressor power switch). The air compressor inflates the multibeam probe compartment through the air charging line. High-pressure air and a drain pump together drain seawater from the multibeam probe compartment, protecting the electrical and automation equipment inside. Crew members can press the self-locking button SB2 to confirm the alarm and silence the extended alarm.

[0024] In this embodiment, the gas pressure in the multi-beam probe cabin is controlled by a two-position mechanism. When the control system initiates a three-level alarm response, the gas pressure in the multi-beam probe cabin is less than or equal to the set lower limit of the pressure relay. The normally open contact PL of the pressure relay closes, the coil of relay four 4KM is energized, contact one 4KM1 of relay four 4KM closes for self-protection, and contact two 4KM2 closes (at this time, the pressure in the multi-beam probe cabin is lower than the set upper pressure limit of the pressure relay, the normally closed contact PH of the pressure relay is closed, and the control circuit is connected), connecting the inflation solenoid valve 7, and the inflation solenoid valve 7 is energized to open. When the gas pressure in the multi-beam probe cabin rises to the set upper pressure limit of the pressure relay, the normally closed contact PH of the pressure relay opens, the coil of relay four 4KM loses power, contact two 4KM2 of relay four 4KM opens, and the inflation solenoid valve 7 is de-energized and closed.

[0025] In this embodiment, the opening and closing of the inflation solenoid valve 7 is controlled in a dual-position manner based on the air pressure in the multi-beam probe cabin. The pressure range depends on the loading, draft and sea conditions of the surveying vessel and can be adjusted according to the actual conditions of the surveying vessel.

[0026] The opening and closing of drain solenoid valve 3 and the start and stop of drain pump 2 are controlled by float switch 2. When the water level drops below water level x, contact 2K2 and contact 3K3 of float switch 2 disconnect, automatically stopping drain pump 2 and closing drain solenoid valve 3. The first-level alarm is controlled by float switch 1, providing real-time monitoring and feedback of the water level in the cabin.
