Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of water tunnel experiments, and in particular relates to a modular traction-type water tunnel device and a use method thereof. Background Art
[0002] Water tunnels are highly effective experimental devices for hydrodynamics research, primarily used to study the interaction between experimental objects and water flow. Within a water tunnel system, pressure and flow rate can be controlled independently, enabling water to be recycled and reused. The cross-sections of water tunnel experimental sections can be shaped in various ways, such as square, rectangular, and circular, enabling multi-angle observation and data recording for scientific research or testing.
[0003] To conduct hydrodynamic experiments, the experimental object and the fluid must achieve the desired relative velocity. Water tunnels can be divided into two categories, depending on the experimental object and the fluid's motion state. The first category, in which the experimental object remains relatively stationary while the fluid medium is in motion, includes circulating and gravity tunnels. The second category, in which the fluid medium remains stationary while the experimental object is in motion, includes traction and spiral-arm tunnels. Circulating tunnels utilize pumps to power reciprocating water through pipes, achieving adjustable and relatively high flow rates. Gravity tunnels, powered by gravity, require no additional power system and often have lower flow rates.
[0004] A towable water tunnel is another type of hydrodynamic experimental equipment. The test object is towed by an electric trailer, hence its name. In 1872, British naval architect W. Froude built the world's first ship model test tunnel in Torquay, England. China completed its first water tunnel in Shanghai in 1954, measuring 70 meters long, 5 meters wide, and 2.5 meters deep. The towable water tunnel at the Xuhui campus of Shanghai Jiao Tong University was completed in 1958. This towable water tunnel is 110 meters long, 6 meters wide, and 3 meters deep, with a maximum towing speed of 6 meters per second. The China Ship Science Research Center completed a large water tunnel in Wuxi in 1965. This tunnel is 474 meters long, 7 meters deep, and has a 14-meter-wide test section. In September 2014, the University of Southampton in the UK completed construction of a new towable water tunnel. The tunnel measures 138 meters long, 6 meters wide, and 3.5 meters wide, respectively, with a maximum towing speed of 12 meters per second. The multifunctional traction water tunnel currently under construction at the Minhang Campus of Shanghai Jiao Tong University is 300m long, 16m wide, and 7.5m deep, with a maximum traction speed of 10m / s.
[0005] These towable water tunnels are often designed and constructed to accommodate large experimental objects, such as ships and submarines. Their high construction costs make them difficult for universities and research institutions to afford. However, a significant portion of hydrodynamic experiments require smaller objects and lower flow rates. Therefore, developing low-cost hydrodynamic experimental equipment to meet these needs is crucial. Summary of the Invention

[0029] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.
[0030] Example 1 See also Figure 1 and Figure 2 The present invention provides a modular traction water tunnel device, comprising a wheel-foot guide rail module 1, a linear motion platform 2, a traction water tunnel 3 and a traction module 4. Figure 3 The wheel-foot guide rail module 1 includes a first track 10 and a second track 11 arranged parallel to each other and a connecting rod 12 connecting the first track 10 and the second track 11. The first track 10 and the second track 11 are both formed by connecting a plurality of circular tubes in pairs, and a pad 13 is provided at the connection between two adjacent circular tubes. The connection between the two circular tubes is locked on the pad 13 by a locking sleeve or other connecting piece, thereby firmly fixing the circular tube on the pad 13 to prevent the wheel-foot guide rail module 1 from being displaced when subjected to force. A plurality of connecting rods 12 are arranged at equal intervals between the first track 10 and the second track 11. The setting of the connecting rods 12 can play a role in controlling the track gauge. The two ends of each connecting rod 12 are correspondingly fixed on the pad 13 connected to the first track 10 and the pad 13 connected to the second track 11. In order to facilitate connection, the two ends of the connecting rod 12 can be fixedly connected to the connecting piece on the corresponding pad 13 by fasteners such as studs. In order to facilitate the adjustment of the track gauge, a plurality of through holes are provided at equal intervals on each connecting rod 12 , and the track gauge can be adjusted by inserting studs into different through holes.
[0031] See also Figure 4The linear motion platform 2 includes a trapezoidal support body 20 and a sliding wheel group arranged at the bottom of the trapezoidal support body 20. In this embodiment, the trapezoidal support body 20 includes four C-shaped steels arranged longitudinally and a plurality of square-shaped steels that connect the four C-shaped steels in pairs transversely. The C-shaped steels and the square-shaped steels are fixedly connected by fasteners such as bolts, thereby facilitating disassembly and assembly. After assembly, the trapezoidal support body 20 has a channel 23 for the dragging water tunnel to pass through. A wheel foot group is provided at the bottom of each C-shaped steel. The wheel foot group includes a first group of wheel feet 21 arranged on the outside of the bottom of the C-shaped steel and a second group of wheel feet 22 arranged on the inside of the bottom of the C-shaped steel. The first group of wheel feet 21 and the second group of wheel feet 22 each include two wheel feet arranged side by side, and the two wheel feet on the first group of wheel feet 21 and the two wheel feet on the second group of wheel feet 22 are arranged in a one-to-one correspondence. The radial extension lines of the two corresponding wheel feet on the first group of wheel feet 21 and the second group of wheel feet 22 are connected to form a V shape. In order to facilitate the linear motion platform to slide on the wheel foot guide rail module 1, the top distance between the first set of wheel feet 21 and the second set of wheel feet 22 is greater than the bottom distance between the first set of wheel feet 21 and the second set of wheel feet 22, and the spacing between the bottoms of the first set of wheel feet 21 and the second set of wheel feet 22 is exactly equal to the diameter of the track so that the spacing between the bottoms of the first set of wheel feet 21 and the second set of wheel feet 22 at the bottom of the C-shaped steel can be slid on the first track 10 and the second track 11, so that the linear motion platform 2 can slide on the wheel foot guide rail module for linear movement.
[0032] See also Figure 5 and Figure 6The towable water tunnel 3 includes a water tunnel support frame that runs through a channel of a linear movable platform and is arranged lengthwise between the wheel-foot guide rail modules, and a waterproof canvas 30 disposed within the water tunnel support frame and used to hold water. The water tunnel support frame includes a horizontally arranged rectangular frame 31, a plurality of first connecting arms 32 inserted downwardly into the rectangular frame 31 and located on one side of the rectangular frame 31, a plurality of second connecting arms 33 inserted downwardly into the rectangular frame 31 and located on the opposite side of the rectangular frame 31, a first connecting shaft 34 rotatably disposed at the bottom of the first connecting arm 32, a second connecting shaft 35 rotatably disposed at the bottom of the second connecting arm 33, and a support plate 36 connecting the opposing first connecting shafts 34 and 35. To reduce costs and facilitate material procurement, the rectangular frame 31 is formed by bending a round tube or by splicing multiple round tube sections. Multiple first connecting arms 32 and corresponding second connecting arms 33 are evenly spaced at the bottom of the rectangular frame 31. In this embodiment, the first connecting arm 32 and the second connecting arm 33 are each composed of two parallel circular tubes. The circular tubes are angled with respect to the vertical direction and are tilted away from the waterproof canvas 30. The angle is greater than 0° and less than 45°, thereby improving the stability of the water tunnel support frame. The bottoms of the two circular tubes comprising the first connecting arm 32 or the second connecting arm 33 are pivotally connected to the ends of the first connecting shaft 34 or the second connecting shaft 35. To enhance the load-bearing capacity of the water tunnel support frame, each set of the first connecting shaft 34 and the second connecting shaft 35 is further connected by a support plate 36. In this embodiment, the support plate 36 is made of canvas. The waterproof canvas 30 is positioned within the interior area enclosed by the rectangular frame 31, the first connecting arm 32, the support plate 36, and the second connecting arm 33, with its edges folded outward and secured to the first connecting shaft 34 and the second connecting shaft 35 via ropes or the like. After assembly, the traction-type water tunnel 3 is positioned within the reserved channel 23 on the linear movable platform 2, and the two are fixedly connected by multiple fasteners.
[0033] When the water tunnel support frame is covered with the waterproof canvas 30 and filled with water, the whole structure will form a self-stable structure. Figure 7It is a right view of the experimental bench, f1 is the force exerted by part of the fluid gravity on the first connecting arm 32 and the second connecting arm 33 through the waterproof canvas 30 and the rectangular frame 31, f2 is the force exerted by the lateral pressure of the fluid on the first connecting arm 32 and the second connecting arm 33 through the waterproof canvas 30, and the appropriate inclination angle of the first connecting arm 32 and the second connecting arm 33 can balance the torques exerted by f1 and f2 on the first connecting arm 32 and the second connecting arm 33. When the first connecting arm 32 / second connecting arm 33 rotates counterclockwise around the first connecting axis 34 / second connecting axis 35 under the action of the lateral force f2, the water in the water hole will be lifted, and the tension f1 applied to the first connecting arm 32 / second connecting arm 33 will rapidly increase, preventing the first connecting arm 32 / second connecting arm 33 from rotating counterclockwise. When the first connecting arm 32 / second connecting arm 33 rotates clockwise around the first connecting axis 34 / second connecting axis 35 under the action of the tension f1, the contact area between the waterproof canvas 30 at the bottom of the water hole and the ground increases, and the tension f1 applied by the fluid will decrease, thus preventing the first connecting arm 32 / second connecting arm 33 from rotating clockwise. Through the above structural design, the gravity and pressure of the water are used to form a solid support structure.
[0034] See also Figure 8 The traction module 4 includes a motor 40 mounted on the ground at one end of the wheel-foot guide module 1, a first driving conveyor pulley 41 axially connected to the motor 40, a second driving conveyor pulley 43 connected to the first driving conveyor pulley 41 via a drive shaft 42, a first driven conveyor pulley 44 positioned opposite the first driving conveyor pulley 41 and located at the other end of the wheel-foot guide module 1, a second driven conveyor pulley 45 positioned opposite the second driving conveyor pulley 43 and located at the other end of the wheel-foot guide module, a first conveyor belt 46 connecting the first driving conveyor pulley 41 and the first driven conveyor pulley 44, and a second conveyor belt 47 connecting the second driving conveyor pulley 43 and the second driven conveyor pulley 45. The C-shaped steel on both sides of the linear motion platform 2 are connected to the first conveyor belt 46 and the second conveyor belt 47 respectively via fasteners such as clips. The first driving conveyor pulley 41 and the first driven conveyor pulley 44 are positioned above the first track 10, while the second driving conveyor belt 43 and the second driven conveyor pulley 45 are positioned above the second track 11. The motor 40 drives the first conveyor belt 46 and the second conveyor belt 47 to move, thereby driving the linear moving platform 2 to move linearly on the wheel-foot guide module 1. At the same time, the dragging water tunnel 3 is driven by the linear moving platform 2 to move linearly.
[0035] When assembling the modular traction-type water tunnel device of this embodiment, first, multiple round tubes are connected in pairs and fixed to the ground through pads 13 to form a first track 10 and a second track 11. Then, multiple connecting rods 12 are fixed to the corresponding pads 13 on the first track 10 and the second track 11 through studs to install the wheel-foot guide rail module 1. After the wheel-foot guide rail module 1 is installed, a motor 40 is set on the ground on one end side of the wheel-foot guide rail module 1. The motor 40 is first connected to the first active transmission pulley 41 through a shaft sleeve and then connected to the second active transmission pulley 43 through a transmission shaft 42. Then, a first driven transmission pulley 44 and a second driven transmission pulley 45 are set on the other end side opposite to the wheel-foot guide rail module 1. The first active transmission pulley 41 and the first driven transmission pulley 44 are connected through a first conveyor belt 46, and the second active transmission pulley 43 and the second driven transmission pulley 45 are connected through a second conveyor belt 47.
[0036] Take a plurality of round tubes and connect or bend them in pairs to form a rectangular frame 31. Then, evenly insert a plurality of first connecting arms 32 and second connecting arms 33 at the bottom of both sides of the rectangular frame 31. The first connecting shaft 34 is rotatably set at the bottom of the first connecting arm 32, and the second connecting shaft 35 is rotatably set at the bottom of the second connecting arm 33. The corresponding first connecting shaft 34 and second connecting shaft 35 are then connected by canvas to form a stable support structure. Afterwards, the waterproof canvas 30 is set in the internal area enclosed by the rectangular frame 31, the first connecting arm 32, the support plate 36 and the second connecting arm 33, and its edges are folded outward and fixed to the first connecting shaft 34 and the second connecting shaft 35 through the eyelets on the waterproof canvas 30 by ropes, etc., so as to form a stable water storage hole. Next, install the linear movable platform, take four C-shaped steels and a plurality of square steels connecting the four C-shaped steels, and connect the two ends of each square steel to the two C-shaped steels by bolts or other fasteners. After the connection is completed, the trapezoidal bracket body 20 has a channel 23 for the dragging water tunnel to pass through, and then a wheel foot group is set at the bottom of each C-shaped steel, and then the four wheel foot groups of the linear movable platform 2 are slidably connected to the wheel foot guide module 1. The installed traction water tunnel 3 is then passed through the channel of the linear movable platform 2 and set on the ground between the first track 10 and the second track 11 along the length direction of the wheel foot guide module 1. Finally, the first conveyor belt 46 and the second conveyor belt 47 are clamped to the C-shaped steel of the linear movable platform 2 by clips or the like. Since the connection method of the present invention is simple and is mostly connected by plugging or fixing with fasteners, the disassembly of the dragging water tunnel device of the present invention is also more convenient and quick.
