Technical Field

[0001] The utility model relates to the technical field of ship design, in particular to a navigation test device for a ship design model. Background Art

[0002] A ship is a general term for various vessels. A ship is a means of transportation that can navigate or berth in waters for transportation or operations, and has different technical performances, equipment, and structural forms according to different usage requirements. A ship is a man-made means of transportation mainly operating in geographical waters. When designing a ship, a reduced-scale model of the ship is first made, and then a navigation test is carried out on the ship design model.

[0014] Compared with the prior art, the beneficial effects of the present utility model are:

[0015] 1. A navigation test device for a ship design model of the present utility model. When the fan for the required test wind direction is turned on, it can conduct a wind resistance test on the ship design model during navigation. At the same time, the fan housing is rotated, and the fan rotates around the damping rotating shaft, enabling the adjustment of the fan angle, and thus the adjustment of the wind direction. It can conduct wind resistance tests on the ship design model at multiple wind directions during navigation, making the test results more comprehensive.

[0016] 2. A navigation test device for a ship design model of the present utility model. When it is necessary to test the navigation situation of the ship design model in a rainy environment, the water pump is started to pump the water in the main water tank into the interior of the second horizontal pipe through the water delivery pipe, and finally sprayed out from the nozzles at the bottom of the second horizontal pipe, which can test the navigation situation of the ship in rainy days. When it is necessary to increase the sprayed water, one or two valves can be opened to make the water transported to the inner cavity of the first horizontal pipe and sprayed out from the nozzles at the bottom of the first horizontal pipe. At this time, the nozzles at the bottoms of the first horizontal pipe and the second horizontal pipe both spray water, which is equivalent to testing the navigation situation of the ship design model in the case of heavy rain and light rain.

[0017] 3. A navigation test device for a ship design model of the present utility model. The water sprayed out by the nozzles falls into the inner cavity of the main water tank. As the water level in the main water tank rises, the water flows into the auxiliary water tank through the connecting pipe, thus avoiding the situation that the water level in the main water tank rises and overflows due to simulated rainfall, so as to ensure the normal progress of the test work.

[0018] 4. A navigation test device for a ship design model of the present utility model. When it is necessary to test the navigation situation of the ship design model when encountering waves, the hydraulic rod is controlled to extend or shorten through an external power supply. The hydraulic rod drives the second movable rod to move left and right through the transmission rod, and the second movable rod drives the first movable rod to move left and right through the connecting rod. The first movable rod and the second movable rod respectively drive the movable plates at the bottom to move left and right. When the two movable plates move left and right, they will push the water forward and generate water waves. When it is necessary to reduce the water waves, the hydraulic rod stops working, and the locking bolt is unscrewed to release the fixation between the connecting rod and the first movable rod. At this time, the hydraulic rod works only to drive the movable plate below the second movable rod to move, thereby generating small waves, so as to test the wave resistance of the ship design model during navigation.

Two limiting holes 17 are formed in both the first movable rod 11 and the second movable rod 12. Two limiting rods 18 are arranged between the first movable rod 11 and the second movable rod 12. The two ends of the limiting rod 18 movably penetrate through the adjacent limiting holes 17 and are fixedly connected with the fixed frame 5. A connecting rod 14 is fixedly connected to the left side of the second movable rod 12. A through hole 15 is formed in the first movable rod 11. The left end of the connecting rod 14 movably penetrates through the through hole 15. A threaded hole is formed in the top of the first movable rod 11. A locking bolt 16 is inserted into the inner cavity of the threaded hole. The locking bolt 16 is in threaded connection with the threaded hole. The bottom end of the locking bolt 16 is matched with the top of the connecting rod 14;

[0030] A transmission rod 21 is fixedly connected to the right side of the second movable rod 12. A hydraulic rod 19 is arranged on the right side of the transmission rod 21.

A plurality of installation plates 26 are respectively fixedly connected with the main water tank 1 and the fixed frame 5.

[0031] Working principle: For a ship design model navigation test device of the present utility model, during use, water is injected into the main water tank 1. As the water level rises, the water flows from the communicating pipe 22 into the auxiliary water tank 2 until the water level in the auxiliary water tank 2 is slightly lower than the water level in the main water tank 1, and then the water injection is stopped. Then, the ship design model is placed in the main water tank 1 for navigation. The air blower 23 in the required test wind direction is turned on, which can conduct a wind resistance test on the ship design model during navigation. At the same time, the outer shell of the air blower 23 is rotated, and the air blower 23 rotates around the damping rotating shaft 25, which can adjust the angle of the air blower 23, and thus can adjust the wind direction. The wind resistance test can be carried out on the ship design model in multiple wind directions during navigation, making the test results more comprehensive;

[0032] When it is necessary to test the navigation situation of the ship design model in a rainy environment, the water pump 3 is started to pump the water in the main water tank 1 into the inner part of the second horizontal pipe 8 through the water delivery pipe 4, and finally sprayed out from the nozzles 10 at the bottom of the second horizontal pipe 8, which can test the navigation situation of the ship in rainy days. When it is necessary to increase the sprayed water, one or two valves 9 can be opened, so that the water is delivered to the inner cavity of the first horizontal pipe 7 and sprayed out from the nozzles 10 at the bottom of the first horizontal pipe 7. At this time, the nozzles 10 at the bottoms of both the first horizontal pipe 7 and the second horizontal pipe 8 spray water, which is equivalent to testing the navigation situation of the ship design model in the case of heavy rain and light rain;

[0033] The water sprayed by the nozzle 10 falls into the inner cavity of the main water tank 1. As the water level in the main water tank 1 rises, the water flows from the connecting pipe 22 into the secondary water tank 2, thus preventing the water level in the main water tank 1 from rising and overflowing due to simulated rainfall, thereby ensuring the normal progress of the test work.

[0034] When it is necessary to test the navigation situation of the ship design model in the face of waves, the hydraulic rod 19 is controlled to extend or retract through an external power supply. The hydraulic rod 19 drives the second movable rod 12 to move left and right through the transmission rod 21. The second movable rod 12 drives the first movable rod 11 to move left and right through the connecting rod 14. The first movable rod 11 and the second movable rod 12 respectively drive the movable plates 13 at the bottom to move left and right. When the two movable plates 13 move left and right, they will push the water forward and generate water waves. When it is necessary to reduce the water waves, stop the hydraulic rod 19 from working, unscrew the locking bolt 16, and release the fixation between the connecting rod 14 and the first movable rod 11. At this time, the hydraulic rod 19 works only to drive the movable plate 13 below the second movable rod 12 to move, thereby generating small waves, so as to be able to test the wave resistance of the ship design model during navigation.
