Description

Technical Field

[0001] The invention relates to a device in the technical field of marine engineering, in particular to a flow-making device. Background Art

[0002] A flow-making device is a mechanical equipment used to create a water flow environment. Flow-making devices have important applications in scientific research, industrial production, entertainment facilities and other fields. They are essential for creating and maintaining a specific fluid environment. Flow-making devices are used in different scenarios. In the field of water conservancy engineering, flow-making devices are devices used to simulate port flow. This equipment can help study and test the impact of water flow, or be used for other hydrological dynamics experiments. The design of a flow-making device usually includes components such as pumps, pipes, and nozzles. The specific type and function of the flow-making device depends on its application purpose and design requirements.

[0003] In traditional flow-making equipment, the flow-making equipment generally adopts a circulation pipeline design. For example, the application number is CN202122540119.6, which is connected to the pool body through a circulation pipeline. The outlet and inlet of the circulation pipeline are respectively located at both ends of the pool body. The water flow is formed in the pool body through the water pump. This type of flow-making equipment cannot make more refined adjustments to the water flow in the later stage, and the experimental data is limited.

[0004] In the invention patent with application number 201810226304.8, a flow-making device for marine engineering experiments is involved. This flow-making device can drive the flow-making nozzle to move up and down perpendicular to the water surface through an electric push rod, and can drive the flow-making nozzle to rotate circumferentially through a disc-shaped gear structure. The plane formed by the circumferential movement is parallel to the water surface. The flow-making nozzle performs a jet in a circumferentially rotating state. The rotation of the flow-making nozzle itself will affect the jet and water flow, which may affect the stability of the experimental data, and this type of flow cannot be made. Compared with traditional flow-making equipment, this invention has only made beneficial improvements in the up and down movement of the flow-making nozzle, and the flow-making direction and effect are limited. Summary of the invention

[0005] The object of the present invention is to provide a flow-generating device which has the advantages of diversified jet modes and jet directions.

[0024] The present invention is further configured as follows: the flow supply component is connected to the ejector via a connecting pipe, and the connecting pipe is made of a flexible material.

[0025] By adopting the above technical solution, due to the existence of the angle adjustment component, the connecting pipe made of flexible material is used to facilitate position adaptation, thereby avoiding the connecting pipe from breaking due to angle adjustment.

The flow-making device 4 is provided with at least one group of flow-making components. The flow-making component is provided with more than two ejectors 401. The output directions of the ejectors 401 of the same group of flow-making components are the same, and the output directions of the ejectors 401 corresponding to the flow-making components belonging to different groups are different. In this embodiment, two flow-making components are provided, but it is not limited to two, and it can also be more than one. The two flow-making components are arranged in a symmetrical relationship, and the output directions of the ejectors 401 of the two groups of flow-making components are arranged in opposite directions, and the ejectors 401 of the flow-making components are arranged evenly spaced.

[0045] See also Figure 7 , the two storage tanks 402 are each connected to a pressure control pump, and the pressure control pump can drive the storage tank 402 to be in a pressurized or negative pressure state. For the convenience of the experiment, the storage tank 402 can store liquid or gas, and the ejector 401 can eject gas or liquid to observe the experimental effects of different media. When the ejector 401 needs to eject liquid, the pressure control pump can pressurize the storage tank 402, cooperate with the regulating switch valve, and drive the liquid in the storage tank 402 to pass through the connecting pipe and the ejector 401 in turn until it is ejected; when the ejector 401 needs to eject gas, the pressure control pump can pressurize the storage tank 402, discharge the liquid first, and then cooperate with the regulating switch valve to drive the liquid in the storage tank 402 to pass through the connecting pipe and the ejector 401 in turn until it is ejected.

[0047] In this embodiment, a valve is provided between the two storage tanks 402, and a liquid level sensor is provided in each of the storage tanks 402. The two groups of flow-generating components are in a spraying state and a absorbing state, respectively. When the liquid in the storage tank 402 of the flow-generating component in the spraying state is about to be insufficient, the liquid in the storage tank 402 of the flow-generating component originally in the absorbing state stops being absorbed and the regulating switch valve of the storage tank 402 is closed, and the storage tank 402 of the flow-generating component originally in the absorbing state is pressurized to a pressure that is the same as the storage tank 402 in the spraying state. At this time, the valve is opened, and the liquid in the storage tank 402 of the flow-generating component originally in the absorbing state is replenished into the storage tank 402 opposite to the spraying state through the valve, which can reduce the liquid replenishment time of the storage tank 402 in the spraying state and thus extend the duration of the experiment.

[0048] The horizontal position of the flow-generating device 4 is adjusted laterally by the first transfer component 1, the ejector 401 can be driven to be immersed in the liquid by the second transfer component 2, and the position of the ejector 401 from the water surface is controlled by the height reverse lifting and lowering, and the initial injection angle of the ejector 401 relative to the horizontal plane is controlled by the angle adjustment component 3. When the ejector 401 is driven to move synchronously by the angle adjustment component 3 and the ejector 401 sprays liquid synchronously, a wavy water flow can be formed to propel it to a distance, and the angle rotation speed of the auxiliary angle angle adjustment component 3 and the different spraying flow rates of the ejector caused by the different pressures of the pressure tank are used to simulate water flow data in different states. Different storage tanks 402 control the relative position of the ejector 401 through the combination of negative pressure and positive pressure of the pressure control pump and the transfer device, so as to achieve different flow-generating effects, thereby obtaining different simulation states and experimental data.
