Description

Technical Field

[0001] The utility model relates to the technical field of ship model experiments, in particular to a device for simulating the resistance experienced by a three-dimensional model ship during navigation. Background Art

[0002] A ship model is a scale model that is made in strict proportion to the shape, structure, color and even interior components of a real ship. Ship models truly reproduce the main features of the original ship and are well-made. They themselves contain ship culture and have high collection value. A carefully collected set of ship models can fully and realistically reproduce the history of a shipping company or a ship brand.

[0003] When simulating the resistance encountered by a three-dimensional model hull during navigation, the simulation needs to be performed on a still water surface. However, the water flow speed in the river varies, and it is difficult to adjust the water flow speed during the simulation. In addition, different degrees of waves may be generated on the water surface in different weather conditions, making simulation more difficult.

[0004] To this end, we proposed a three-dimensional model hull resistance simulation device to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a device for simulating the resistance experienced by a three-dimensional model ship during navigation, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A device for simulating the resistance experienced by a three-dimensional model ship during navigation, comprising:

[0008] A cell body, wherein a circulation cavity is provided in the cell body, and the circulation cavity is connected to the interior of the cell body through a connecting channel;

[0009] A wave simulation mechanism for simulating waves within a pool, the wave simulation mechanism comprising a cavity disposed within the pool, a baffle disposed within the cavity, the upper end of the baffle slidingly penetrating the pool and extending into the pool, a crankshaft rotatably connected within the cavity, a first motor fixedly connected within the cavity, a drive shaft of the first motor coaxially and fixedly connected to the crankshaft, a deflector rotatably connected to a curved portion of the crankshaft, the upper end of the deflector rotatably connected to the lower end of the baffle;

[0010] A water flow generating mechanism is used to drive the water in the pool body. The water flow generating mechanism includes an L-shaped plate that is slidingly connected to the left side of the inner wall of the pool body. An inclined plate is provided in the L-shaped plate. A plurality of nozzles are installed on the inclined plate. The inclined plate is fixedly connected to the L-shaped plate through a fixed plate. A water pump is fixedly installed in the circulation chamber. The plurality of nozzles are all connected to the water pump. A lifting mechanism for lifting the L-shaped plate is provided in the pool body.

[0011] Furthermore, the lifting mechanism includes two grooves arranged on the inner side of the pool body, and threaded rods are rotatably connected in the two grooves. Threaded blocks are threadedly sleeved on the outside of the two threaded rods, and the two threaded blocks are fixedly connected to the L-shaped plate. A transmission cavity is provided in the pool body, and the lower ends of the two threaded rods rotate through the pool body and extend to be arranged in the transmission cavity. The two threaded rods are connected by a transmission mechanism, and a second motor is installed at the upper end of the pool body. The drive shaft of the second motor rotates through the pool body and is coaxially fixedly connected to one of the threaded rods.

[0012] Furthermore, the transmission mechanism includes two pulleys, the two pulleys are coaxially fixedly connected to two threaded rods respectively, and the two pulleys are connected through a synchronous belt transmission.

[0013] Furthermore, a plurality of the nozzles are evenly distributed in an array on the inclined plate, and the nozzles are located in a direction of the inclined plate away from the inner side of the L-shaped plate.

[0014] Furthermore, the L-shaped plate is located on the left side of the pool body, and the baffle is located at the left 1 / 3 of the pool body.

[0015] Compared with the prior art, the beneficial effects of the present invention are at least:

[0016] 1. By setting up a wave simulation mechanism, the first motor drives the crankshaft to rotate, and the crankshaft drives the baffle to move back and forth through the deflection plate. During the flow of water, waves can be generated. When the baffle moves back and forth at a faster speed and the water flow is larger, the waves generated are larger. When the baffle moves back and forth at a slower speed and the water flow is smaller, the waves generated are smaller. Different waves can be simulated, and the simulation is relatively simple.

[0017] 2. By setting up a water flow generating mechanism, the two threaded rods are driven to rotate by the second motor, and the two second threaded rods drive the L-shaped plate to rise and fall through the two threaded blocks. The L-shaped plate drives the inclined plate to rise and fall through the fixed plate until it is in a suitable position. When the L-shaped plate is in a higher position and the water pumping volume is larger, a water flow with a larger flow rate can be created. When the L-shaped plate is in a lower position and the water pumping volume is smaller, a water flow with a smaller flow rate can be created. The water flow speed can be adjusted, and the adjustment is more convenient.

[0018] The utility model can adjust the size of the water flow, generate waves, and adjust the size of the waves, and is more accurate in simulating the sailing resistance of the three-dimensional model ship. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] See also Figures 1 to 5 , a device for simulating the resistance of a three-dimensional model ship during navigation, comprising:

[0027] The pool body 1 has a circulation chamber 2 in the pool body 1, and the circulation chamber 2 is connected to the interior of the pool body 1 through a connecting channel 3;

[0028] In order to simulate the resistance of the three-dimensional model ship to navigation by simulating waves, a wave simulation mechanism 4 is provided to simulate the waves in the pool body 1. The wave simulation mechanism 4 includes a cavity 5 provided in the pool body 1, a baffle 6 is provided in the cavity 5, the upper end of the baffle 6 slides through the pool body 1 and extends to the pool body 1, a crankshaft 7 is rotatably connected in the cavity 5, a first motor 8 is fixedly connected in the cavity 5, a drive shaft of the first motor 8 is coaxially fixedly connected to the crankshaft 7, a deflector 9 is rotatably connected to the curved portion of the crankshaft 7, and the upper end of the deflector 9 is rotatably connected to the lower end of the baffle 6;

[0029] Through the above technical features, the crankshaft 7 is driven to rotate by the first motor 8, and the crankshaft 7 drives the baffle 6 to rise and fall reciprocally through the deflection plate 9. During the flow of water, waves can be generated. When the baffle 6 reciprocates and rises at a faster speed and the water flow is larger, the waves generated are larger. When the baffle 6 reciprocates and rises at a slower speed and the water flow is smaller, the waves generated are smaller. Different waves can be simulated.

[0030] In order to simulate the size of the water flow and the resistance encountered by the three-dimensional model ship during navigation, a water flow generating mechanism 10 is set up to drive the water in the pool body 1. The water flow generating mechanism 10 includes an L-shaped plate 11 that is slidably connected to the left side of the inner wall of the pool body 1. It should be noted that the L-shaped plate 11 is located on the left side of the inside of the pool body 1, and the baffle 6 is located at 1 / 3 of the left side of the pool body 1. An inclined plate 12 is provided in the L-shaped plate 11, and a plurality of nozzles 13 are installed on the inclined plate 12. It is worth mentioning that a plurality of nozzles 13 are evenly distributed in an array on the inclined plate 12, and the nozzles 13 are located in the direction of the inclined plate 12 away from the inner side of the L-shaped plate 11. The inclined plate 12 is fixedly connected to the L-shaped plate 11 through a fixed plate 14. A water pump 15 is fixedly installed in the circulation chamber 2, and a plurality of nozzles 13 are connected to the water pump 15. A lifting device for lifting the L-shaped plate 11 is provided in the pool body 1. Mechanism 16. It should be noted that the lifting mechanism 16 includes two grooves 17 arranged on the inner side of the pool body 1, and threaded rods 18 are rotatably connected in the two grooves 17. The two threaded rods 18 are threadedly sleeved with threaded blocks 19 on the outside. The two threaded blocks 19 are fixedly connected to the L-shaped plate 11. A transmission cavity 20 is provided in the pool body 1. The lower ends of the two threaded rods 18 rotate through the pool body 1 and extend into the transmission cavity 20. The two threaded rods 18 are connected through a transmission mechanism 21. It should be noted that the transmission mechanism 21 includes two pulleys 23, which are coaxially fixedly connected to the two threaded rods 18 respectively, and the two pulleys 23 are connected through a synchronous belt transmission. A second motor 22 is installed at the upper end of the pool body 1. The drive shaft of the second motor 22 rotates through the pool body 1 and is coaxially fixedly connected to one of the threaded rods 18.

[0031] Through the above technical features, the two threaded rods 18 are driven to rotate by the second motor 22, and the two threaded rods 18 drive the L-shaped plate 11 to rise and fall through the two threaded blocks 19. The L-shaped plate 11 drives the inclined plate 12 to rise and fall through the fixed plate 14 until it reaches a suitable position. When the L-shaped plate 11 is in a higher position and the water pump 15 pumps a larger amount of water, a larger flow of water can be created. When the L-shaped plate 11 is in a lower position and the water pump 15 pumps a smaller amount of water, a smaller flow of water can be created, and the speed of the water flow can be adjusted.

[0032] Working principle:

[0033] 1) Simulating the effect of water flow on the navigation resistance of the three-dimensional model ship: The second motor 22 drives the two threaded rods 18 to rotate, and the two threaded rods 18 drive the L-shaped plate 11 to rise and fall through the two threaded blocks 19. The L-shaped plate 11 drives the inclined plate 12 to rise and fall through the fixed plate 14 until it reaches a suitable position. When the L-shaped plate 11 is at a higher position and the water pump 15 pumps a larger amount of water, a larger flow of water can be generated. When the L-shaped plate 11 is at a lower position and the water pump 15 pumps a smaller amount of water, a smaller flow of water can be generated, thereby adjusting the speed of the water flow.

[0034] 2) Simulate the resistance of the three-dimensional model ship to the effects of wave size: The crankshaft 7 is driven to rotate by the first motor 8, and the crankshaft 7 drives the baffle 6 to rise and fall back through the deflection plate 9. Waves are generated during the flow of water. When the baffle 6 reciprocates and rises faster and the water flow is larger, the waves generated are larger. When the baffle 6 reciprocates and rises slower and the water flow is smaller, the waves generated are smaller. Different waves can be simulated.
