[0001] The present invention relates to the technical field of wave experiments, and particularly relates to a laboratory uniform flow field simulation system and a simulation method. Background Art

[0002] At present, various wave and water flow experiments in the laboratory use submersible pumps to simulate the flow field. The generated water flow is uneven (the flow velocity is large on the pump axis and small between the pumps). Therefore, a long distance is required to make the water flow stable and uniform, and its flow rate cannot be accurately controlled. Therefore, we propose a laboratory uniform flow field simulation system and a simulation method to solve the above-mentioned problems. Summary of the Invention

[0003] The purpose of this application is to provide a laboratory uniform flow field simulation system and a simulation method to solve the problem that the use of a submersible pump in the above background art generates uneven water flow. Therefore, a long distance is required to make the water flow stable and uniform, and its flow rate cannot be accurately controlled.

[0004] To achieve the above purpose, this application provides the following technical solution: A laboratory uniform flow field simulation system includes a control box, multiple water pumps and a rectifying box. The control box is electrically connected to the multiple water pumps respectively, and the water pumps are connected to the rectifying box through hoses, and a flow meter is installed on the hose.

[0006] A power component is installed on the rear inner wall of the rectifying box, and the front side of the power component extends into the confluence box and is connected to two flow-blocking and resistance components. The flow-blocking and resistance components are connected to the inner wall of the confluence box, and a plurality of nozzles are fixedly installed at equal intervals on the right inner wall of the confluence box. The right ends of the nozzles extend into the rectifying box.

[0007] With the above structure, after connecting the water pump to the external water pipe, at this time, the water pump is used to transport water to the confluence box through the connecting component. Under the action of the two flow-blocking and resistance components, the initial reduction of the water flow velocity can be realized, so as to reduce the water flow impact.

The front end of the driving shaft extends into the confluence box and is connected to the gear component, and the gear component is connected to the two flow-blocking members.

[0017] Furthermore, by starting the adjustment motor to drive the driving bevel gear to rotate, at this time, under the meshing transmission of the connecting bevel gear, the driving shaft can be driven to rotate. Then, under the transmission of the gear component, the two flow-blocking members can be driven to operate simultaneously.

[0018] Preferably, the gear component includes a support member, a rotating toothed ring, a bevel gear ring, a transmission bevel gear, and two driving gears;

[0019] The support member is installed on the bottom inner wall of the confluence box.

The transmission bevel gear is fixedly installed at the front end of the driving shaft, and the transmission bevel gear meshes with the bevel gear ring. The driving gears are connected to the corresponding flow-blocking members, and the two driving gears are both meshed with the rotating toothed ring.

[0020] Further, when the driving bevel gear rotates with the driving shaft, under the meshing drive of the bevel gear ring, the rotating gear ring can be driven to rotate, and then under the meshing drive of the two driving gears, the two flow-blocking members can be driven to move.

[0021] Preferably, the support member includes a slip ring and two sliding plates;

[0022] The slip ring is fixedly installed on the bottom inner wall of the rectifying box, the two sliding plates are symmetrically slidably connected to the slip ring, and both sliding plates are fixedly connected to the bottom of the rotating gear ring.

[0033] 1. In the present invention, the control box can control the start of multiple water pumps and the delivery flow rate of the water pumps. The water can be transported into the collection box through a hose and then into the confluence box through a connecting pipe. When the water flows in the confluence box, under the blocking effect of multiple baffle nets, the flow rate will be reduced. Then the water can be ejected from multiple nozzles. At this time, an impact force will be generated on the arc-shaped flow retarder plate. Under the action of the arc-shaped flow retarder plate, the impact force of the water flow can be blocked again until the water can be discharged from the drain hole, and the net plate is used to block the impact force of the water flow again, so that the discharged water flow can form a uniform flowing state;

[0034] 2. In the present invention, after the flow rate of the water pump increases, the regulating motor can be started to drive the driving bevel gear to rotate. Under the meshing transmission of the connecting bevel gear, the driving shaft can be driven to rotate. When the driving shaft rotates, under the meshing transmission of the transmission bevel gear and the bevel gear ring, the rotating toothed ring can be driven to rotate. At this time, under the meshing transmission with the two driving gears, the two support shafts can be driven to rotate, so as to adjust the positions of the four baffle nets, increase the contact area between the baffle nets and the water, and thus increase the blocking force on the water, making the water flow smoothly;

[0035] When the present invention transports water into the confluence box and the rectifying box, multiple baffle nets and the arc-shaped flow retarder plate can rectify the water, thereby eliminating the impact force of the water flow and enabling the water to flow out smoothly from the rectifying box. Therefore, the problem of uneven water flow can be eliminated, and it has good practicability. BRIEF DESCRIPTION OF THE DRAWINGS

[0060] In this embodiment, the gear member includes a support member, a rotating gear ring 24, a bevel gear ring 20, a driving bevel gear 19 and two driving gears 23;

[0061] The support member is installed on the inner bottom wall of the confluence box 6. The rotating gear ring 24 is connected to the support member, and the bevel gear ring 20 is fixedly sleeved on the rotating gear ring 24. The driving bevel gear 19 is fixedly installed at the front end of the driving shaft 16, and the driving bevel gear 19 meshes with the bevel gear ring 20. The driving gear 23 is connected to the corresponding flow-blocking member, and both driving gears 23 mesh with the rotating gear ring 24.

[0062] When the driving bevel gear 19 rotates along with the driving shaft 16, at this time, under the meshing drive of the bevel gear ring 20, the rotating gear ring 24 can be driven to rotate. Then, under the meshing drive of the two driving gears 23, the two flow-blocking members can be driven to move.

[0063] In this embodiment, the support member includes a slip ring 26 and two sliding plates 27;

[0064] The slip ring 26 is fixedly installed on the inner bottom wall of the rectifying box 5. The two sliding plates 27 are symmetrically and slidably connected to the slip ring 26, and both sliding plates 27 are fixedly connected to the bottom of the rotating gear ring 24.

[0067] The support shaft 21 is rotatably connected in the confluence box 6, and the driving gear 23 is fixedly sleeved on the support shaft 21. The two frames 22 are symmetrically and fixedly installed on the support shaft 21, and the retaining net 25 is fixedly embedded in the corresponding frame 22.

[0068] By adjusting the angle of the retaining net 25, the contact surface with water can be adjusted so as to adjust the impact force of water.

[0069] The present invention also proposes a simulation method for a laboratory uniform flow field simulation system, including the following steps:

[0070] S1: Connect the water pump 2 to the external water pipe;

[0071] S2: Operate the control box 1 to start multiple water pumps 2 at the same time to pressurize and transport water;

[0072] S3: After the water enters the confluence box 6, the water can be rectified to reduce the water flow impact force. Then, after passing through the arc-shaped flow-slowing plate 12, the water can be decelerated again, so that the water can be smoothly discharged from the drain hole;

The water can be delivered into the collection box 8 through the hose 3, and then can be delivered into the confluence box 6 through the connecting pipe 7. When the water flows in the confluence box 6, under the blocking effect of multiple baffle nets 25, the flow rate will be reduced. Then the water can be ejected from multiple spray pipes 10. At this time, an impact force will be generated on the arc-shaped slow-flow plate 12. Then, under the action of the arc-shaped slow-flow plate 12, the impact force of the water flow can be blocked again until the water can be discharged from the drain holes, and the net plate 13 is used to block the impact force of the water flow again. In this way, the discharged water flow can be made to flow in a uniform state.

When the driving shaft 16 rotates, under the meshing transmission of the transmission bevel gear 19 and the bevel gear ring 20, the rotating toothed ring 24 can be driven to rotate. At this time, under the meshing transmission with the two driving gears 23, the two support shafts 21 can be driven to rotate, so as to adjust the positions of the four baffle nets 25, increase the contact area between the baffle nets 25 and the water, and thus increase the blocking force on the water, making the water flow smoothly. Therefore, the problem of uneven water flow can be eliminated, and it has good practicability.
