[0002] In the process of general ship navigation, the seawater door is easily blocked by external marine waste, causing the suction side of the seawater pump to be low pressure, thereby causing the central cooler to not work normally, and further affecting the fresh water cooling of the main engine, main generator and other equipment, so that each device cannot operate normally. Based on this situation, seawater needs to be circulated. The seawater door is generally installed with a grid, and the gap between the grids is easy to cause blockage. At present, when the seawater door is blocked, compressed air pipeline blowing or steam pipeline blowing is generally used. However, when the compressed air or steam completely invades the water, the water resistance is very large, and it is difficult to effectively and timely blow away the blockage of the seawater door, resulting in the problem of the seawater door blockage cannot be effectively solved.

DETAILED DESCRIPTION

[0023] The shape, structure, mutual position and connecting relationship between parts, the function and working principle of each part of the specific embodiment of the utility model are further explained in detail by the description of the embodiment with reference to the drawings:

[0024] As shown in the drawing, Figure 1 - the drawing, Figure 2 The utility model discloses a ship seawater door anti-blocking structure, and the seawater door 1 is connected with the storage component 3 through the first pipeline 2, the second pipeline 4 connected with the storage component 3 is connected with the side position 5, and the third pipeline 6 connected with the storage component 3 is connected with the upper position of the seawater door 1, and the seawater door 1 comprises the grid 7.The storage component 3 is a ship central cooler.The above-mentioned structure is directed to the deficiency in the prior art, and the improved technical scheme is provided.The seawater door 1 is arranged, the seawater door 1 is used for the passage of seawater, the seawater is transported to the storage component 3 through the first pipeline 2, the storage component 3 is a ship central cooler, and then the seawater is used for cooling the ship central cooler.The storage component 3 is additionally provided with the second pipeline 4 and the third pipeline 6, the second pipeline 4 is used for transporting the seawater after the cooler to the side position 5 and then discharging from the side position 5.The third pipeline 6 is used for guiding part of the seawater to the position of the seawater door 1, and the seawater door 1 is impacted by the seawater under pressure, so that the marine external waste articles blocking the seawater door 1 can be cleaned, the seawater can be normally transported to the storage component 3 through the seawater door 1 by the first pipeline 2, and sufficient seawater can be reliably provided to cool the cooler.The ship seawater door anti-blocking structure has the advantages of simple structure and effective solution to the seawater door blocking problem.

[0025] The first pipeline 2 is provided with a first valve 8 and a seawater pump 9. The second pipeline 4 is provided with a second valve 11 and a second water pump. The third pipeline 6 is provided with a third valve 12. The above structure, the seawater pump is used for pumping seawater into the storage part 3. In the state that the seawater door is not blocked, the first valve 8 is in the normally open state, the second valve 11 is in the normally open state, the third valve 12 keeps the normally closed state, and the seawater flowing through the central cooler is directly discharged from the side position after completing the cooling. When the seawater blocks the seawater door 1, the actual pressure value detected by the pressure sensor 13 close to the inlet of the seawater pump 9 is less than the set low pressure, the alarm 14 feeds back a signal to the control part, and the control part controls the third valve 12 to open. Part of the seawater is guided to the seawater door 1 position through the third pipeline 6, and the seawater door 1 is impacted, so that the seawater door is blocked by the external waste on the sea, so that sufficient seawater can be supplied to the storage part, the normal operation of the central cooler is ensured, and the normal sailing of the ship is ensured.

[0026] The filter 10 is further arranged between the first valve 8 and the seawater pump 9 of the first pipeline 2. The above structure, the filter 10 is used for filtering impurities in the seawater transported by the first pipeline 2.

[0027] The first pipeline 2 is provided with a pressure sensor 13, and the pressure sensor 13 is connected with an alarm 14. The above structure, when the seawater blocks the seawater door 1, the actual pressure value detected by the pressure sensor close to the inlet of the seawater pump 9 is less than the set low pressure, the alarm feeds back a signal to the control part, and the control part controls the third valve 12 to open. In this way, the seawater pressure is monitored in real time, and once the blockage occurs, the external intervention is carried out to clean the blockage.

[0028] The first valve 8, the second valve 11 and the third valve 12 are all electrically controlled valves. The pressure sensor 13 and the alarm 14 are respectively connected with a control part. The first valve 8, the second valve 11 and the third valve 12 are respectively connected with the control part. The above structure, the opening and closing of each valve can be reliably controlled through the control part, and the association is established between the pressure sensor, the alarm, the control part and the valve, and the automatic control is realized. The structure of the utility model can effectively solve the problem that the seawater door 1 is blocked, the central cooler is not running or the running effect is poor, so that the situation that the cooling state of each equipment of the ship is poor, the high temperature is not running or the machine is stopped is avoided, and the ship can be normally sailed in the process of normal sailing without frequent maintenance.

[0029] The ship seawater door anti-blocking structure, when seawater does not block the seawater door 1, the first valve and the second valve are always opened, the third valve is closed, at this time the first pipeline 2 normally transports seawater to supply the central cooler to cool, and the cooled seawater is discharged through the second pipeline 4. When seawater blocks the seawater door 1, the actual pressure value detected by the pressure sensor 13 close to the inlet of the seawater pump 9 is less than the set low pressure value, the alarm 14 connected with the pressure sensor feeds back a signal to the control component, the control component controls the third valve 12 to open, part of seawater is introduced to the seawater door 1 position through the third pipeline 6, and the seawater door 1 is impacted, so that the seawater door blocked by marine external waste articles can be washed away, so that sufficient seawater can be supplied to the storage component, the normal operation of the central cooler is ensured, and normal navigation of the ship is ensured.

[0030] The utility model has been described above in conjunction with the drawings, and obviously, the specific implementation of the utility model is not limited by the above-mentioned mode, as long as various improvements are made by adopting the method concept and technical scheme of the utility model, or the concept and technical scheme of the utility model is directly applied to other occasions without improvement, and all fall within the protection scope of the utility model.
