Description

Technical Field

[0001] The present invention relates to the technical field of amphibious ships, and particularly to an amphibious oil spill emergency rescue system. Background Art

[0002] Existing amphibious oil spill emergency rescue ships usually have an oil storage tank installed in the ship. During the process of collecting oil spills on the water, the amphibious oil spill emergency rescue ship collects the oil-water mixture on the water surface into the oil storage tank. When the oil storage tank is full, the amphibious oil spill emergency rescue ship needs to be driven to the shore, and the oil-water mixture in the oil storage tank is pumped to the oil storage device on the shore through an oil pump installed on the shore. The whole process requires the amphibious oil spill emergency rescue ship to frequently repeat the actions of collecting and storing oil spills, resulting in low oil spill collection efficiency. Moreover, since the weight of the oil storage tank directly participates in the buoyancy calculation of the amphibious oil spill emergency rescue ship, the amount of oil-water mixture carried by the oil storage tank each time is relatively small.

A liquid collection tank 56 is arranged at the bottom of the oil-water separation tank 54 corresponding to the lower part directly below the oil spill buffer pipe 53. A buffer overflow cover 55 is arranged between the bottom of the oil spill buffer pipe 53 and the liquid collection tank 56. The bottom of the liquid collection tank 56 is provided with an opening and leads to a spherical cavity 57. The bottom of the spherical cavity 57 is connected to a drain pipe 59.

An oil pump 67 is arranged at the bottom of the oil storage tank 66, and the oil pump 67 is connected to the oil pipeline 68.

[0028] It should be further noted that for the amphibious oil spill cleaning and collection device 2, the oil-water mixture after cleaning and collection enters the oil spill buffer pipe 53 through the oil-water mixture input pipe 51. Solids and impurities in the oil-water mixture are discharged through the filter screen 52. The oil-water mixture flushes downward from the oil spill buffer pipe 53 and the water flow impact is reduced at the buffer overflow cover 55. The oil-water mixture overflows smoothly from the overflow buffer cover and flows to the spherical cavity 57 through the liquid collection tank 56. When the water level in the oil-water separation tank 54,

[0029] A solenoid valve 58 is provided at the connection between the drain pipe 59 and the spherical cavity 57, a first float liquid level switch 61 is provided inside the spherical cavity 57, a second float liquid level switch 62 and a third float liquid level switch 63 are also provided in the oil-water separation box 54, the second float liquid level switch 62 is provided near the bottom of the oil-water separation box 54, the third float liquid level switch 63 is provided near the top of the oil-water separation box 54, the density of the floats in the first float liquid level switch 61, the second float liquid level switch 62 and the third float liquid level switch 63 are the same, and the density values ​​of the three floats are greater than the density of the oil spill and less than the density of water, the first float liquid level switch 61, the second float liquid level switch 62, the third float liquid level switch 63 and the solenoid valve 58 are all connected to the PLC controller.

[0030] It needs to be further explained that the solenoid valve usually requires a DC 24V voltage power supply. The positive pole is connected to the 24V power supply through the red line, and the negative pole is connected to the output point of the PLC. When the output point of the PLC is activated, the negative pole line of the solenoid valve is connected to the common point, so that the solenoid valve is energized and performs an action; the float level switch triggers the internal microswitch through the float as the liquid level rises and falls, and outputs a normally open or normally closed switch signal. The common end of the float level switch is connected to the common end of the PLC input module, and the NO / NC contact end of the float level switch is connected to the digital input channel of the PLC. The positive pole of the PLC input module power supply is connected in series with the contact end of the float level switch. When the liquid level reaches a high level, the NO contact of the float level switch closes, and the PLC input channel detects a high-level signal to trigger the control logic.

[0031] It should be further explained that in order to prevent the oil-water mixture collected by the oil suction pump from directly rushing into the oil-water separation box 54 and destroying the oil-water interface of the oil-water mixture, an oil overflow buffer pipe 53 and a buffer overflow cover 55 are provided so that the oil-water mixture maintains a stable oil-water interface when entering the oil-water separation box 54, and a liquid collecting tank 56 is provided so that the oil-water mixture escaping from the buffer overflow cover 55 can escape into the liquid collecting tank 56 as soon as possible, and flow into the spherical cavity 57 below through the liquid collecting tank 56; further, since the amphibious ship 1 belongs to water operations, the amphibious ship 1 is at work It is easy to shake continuously during operation, resulting in irregular fluctuations in the oil-water interface. In order to ensure that the spilled oil will not be drawn into the bottom drain pipe 59 with the shaking, a spherical cavity 57 is arranged to cooperate with the first float liquid level switch 61 and the second float liquid level switch 62. When the oil-water interface completely reaches the second float liquid level switch 62, the bottom solenoid valve 58 will be automatically opened for drainage. When the oil-water interface is lower than the second float liquid level switch 62, the bottom solenoid valve 58 will be automatically closed to continue to accumulate the oil-water mixture to ensure that the water discharged from the drain pipe 59 is not mixed with the spilled oil.

[0032] It should be further explained that the state of the oil-water mixture in the oil-water separation box 54 is divided into nine situations:

[0033] First, the oil liquid level and the water liquid level of the oil-water mixture do not reach the height of the first float level switch 61, and the water liquid level does not reach the height of the first float level switch 61. At this time, the first float level switch 61, the second float level switch 62, and the third float level switch 63 are all in an untriggered state. At this time, the PLC controller controls the solenoid valve 58 to close, and the oil suction pump works.

[0034] Second, the oil liquid level of the oil-water mixture reaches the height of the first float level switch 61 but is less than the height of the second float level switch 62, and the water liquid level does not reach the height of the first float level switch 61. At this time, the first float level switch 61, the second float level switch 62, and the third float level switch 63 are all in an untriggered state. At this time, the PLC controller controls the solenoid valve 58 to close, and the oil suction pump works.

[0035] Third, the oil liquid level of the oil-water mixture reaches the height of the second float level switch 62 but is less than the height of the third float level switch 63, and the water liquid level does not reach the height of the first float level switch 61. At this time, the first float level switch 61, the second float level switch 62, and the third float level switch 63 are all in an untriggered state. At this time, the PLC controller controls the solenoid valve 58 to close, and the oil suction pump works.

[0036] Fourth, the oil liquid level of the oil-water mixture reaches the height of the third float level switch 63, and the water liquid level does not reach the height of the first float level switch 61. At this time, the first float level switch 61 and the second float level switch 62 are both in an untriggered state, and the third float level switch 63 is in a triggered state. At this time, the PLC controller controls the solenoid valve 58 to close, and the oil suction pump stops working.

[0037] Fifth, the oil liquid level of the oil-water mixture is between the first float level switch 61 and the second float level switch 62, and the water liquid level is between the first float level switch 61 and the second float level switch 62. At this time, the first float level switch 61 is in a triggered state, the second float level switch 62 is in an untriggered state, and the third float level switch 63 is in an untriggered state. At this time, the PLC controller controls the solenoid valve 58 to close, and the oil suction pump works.

[0038] Sixth, the oil liquid level of the oil-water mixture is between the second float level switch 62 and the third float level switch 63, and the water liquid level is between the first float level switch 61 and the second float level switch 62. At this time, the first float level switch 61 is in a triggered state, the second float level switch 62 is in an untriggered state, and the third float level switch 63 is in an untriggered state. At this time, the PLC controller controls the solenoid valve 58 to close, and the oil suction pump works.

[0039] For the seventh case, the oil liquid level of the oil-water mixture reaches the height of the third float level switch 63, and the water liquid level is between the first float level switch 61 and the second float level switch 62. At this time, the first float level switch 61 is in the triggered state, the second float level switch 62 is in the untriggered state, and the third float level switch 63 is in the triggered state. At this time, the PLC controller controls the solenoid valve 58 to close, and the oil suction pump stops working.

[0040] For the eighth case, the oil liquid level of the oil-water mixture is between the second float level switch 62 and the third float level switch 63, and the water liquid level is between the second float level switch 62 and the third float level switch 63. At this time, the first float level switch 61 is in the triggered state, the second float level switch 62 is in the triggered state, and the third float level switch 63 is in the untriggered state. At this time, the PLC controller controls the solenoid valve 58 to open, and the oil suction pump works.

[0041] For the ninth case, the oil liquid level of the oil-water mixture reaches the height of the third float level switch 63, and the water liquid level is between the second float level switch 62 and the third float level switch 63. At this time, the first float level switch 61 is in the triggered state, the second float level switch 62 is in the triggered state, and the third float level switch 63 is in the triggered state. At this time, the PLC controller controls the solenoid valve 58 to open, and the oil suction pump stops working.

[0042] The third float level switch 63 is mainly used to be linked with the oil suction pump to prevent the explosion of the oil-water separation tank 54 caused by the high content of spilled oil in the oil-water mixture and the slow oil-water separation speed, while the oil suction pump continuously inputs the oil-water mixture into the oil-water separation tank 54, resulting in the overflow of the spilled oil and filling the oil-water separation tank 54.

[0043] The second float level switch 62 is mainly used to monitor the position of the water liquid level in the oil-water mixture. When the water liquid level in the oil-water mixture crosses the second float level switch 62, it ensures that the spherical cavity 57 is filled with water. At this time, the normal bumping and shaking of the amphibious ship 1 will not affect the water in the spherical cavity 57. At this time, the PLC controller controls the solenoid valve 58 to open, and the water is discharged from the spherical cavity 57.

[0044] The first float level switch 61 is mainly used for alarm when the liquid level angle is extreme or the inlet of the spherical cavity 57 is blocked, that is, when the second float level switch 62 is in the triggered state, but the first float level switch 61 is in the untriggered state. At this time, the signal is transmitted to the PLC controller for alarm.

[0045] Working process and principle of the present invention: During the continuous forward movement of the amphibious boat 1, the oil absorption roller 24 is continuously tumbled by driving the motor through the PLC controller. The oil guide plate 28 of the amphibious oil spill cleaning and collection device 2 collects the oil-water mixture on the water surface into the oil collection tank 21 through the oil absorption roller 24. The oil suction pipe 23 is connected to the oil suction pump in the oil collection tank 21 and sucks the oil-water mixture into the oil-water mixture input pipe 51 through the oil suction pump. The oil-water mixture separates solid impurities and waterweeds in the oil-water mixture through the filter screen 52. The oil-water mixture further enters the buffer overflow hood 55 through the oil spill buffer pipe 53. The buffer overflow hood 55 decelerates the high-flow and high-velocity oil-water mixture and discharges it along the oil spill buffer hood. The oil-water mixture flows into the spherical cavity 57 under the guiding action of the liquid collection tank 56. The oil-water mixture continuously replenishes the oil-water separation tank 54. Since the high-density water is concentrated at the lower end and the low-density oil spill floats on the water surface;

[0046] The oil-water mixture presents a total of nine states in the oil-water separation tank 54. According to these nine states, the first float level switch 61, the second float level switch 62, and the third float level switch 63 transmit corresponding electrical signals to the PLC controller. The PLC controller controls the working states of the solenoid valve 58 and the oil suction pump and issues an alarm in the corresponding states. The oil spill in the oil-water mixture continuously drips into the oil guide pipe 65 through the oil-water separation membrane 64 and leads to the oil storage tank 66. The oil spill in the oil storage tank 66 is then transported to the oil transmission pipe 68 through the oil pump 67. The separated oil spill in the oil transmission pipe 68 further enters the oil storage bag 41 through the oil transmission pipe 68. The oil storage bag 41 is connected to the amphibious boat 1 through the towing rope and is towed forward by the amphibious boat 1. The water in the oil-water mixture is directly discharged outside the ship through the drain pipe 59.
