Abstract
Description
Technical Field
[0001] This utility model belongs to the field of river diversion facilities, and more specifically, relates to a flow obstruction and diversion device for reciprocating flow in plain river networks. Background Technology
[0002] Plain river network areas are characterized by weak hydrodynamics and unstable river flow, easily resulting in reciprocating flows. Therefore, when diverting floods and polluted water bodies in plain river network areas, it is often difficult to control the river flow direction. Traditional pumping and drainage methods consume a lot of energy, have high control costs, and are difficult to control the spread of pollutants, resulting in poor control effects. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a flow-blocking and guiding device for reciprocating flow in plain river networks. This device utilizes the Tesla valve principle to construct a simple flow-blocking and guiding structure in plain river network areas, enabling the control of river water flow direction under certain hydrological conditions, achieving precise prevention and control in protected areas. Furthermore, this flow-blocking and guiding structure is characterized by its simple design and construction, low economic cost, and good prevention and control effect.
[0004] To achieve the above objectives, this utility model provides a flow-blocking and guiding device for reciprocating flow in plain river networks, comprising:
[0005] Multiple guide vanes are installed on both sides of the river channel bank. The guide vanes are in the shape of Tesla valves and all the guide vanes are arranged in the same direction on the river channel bank.

[0026] Preferred embodiments of the present invention will now be described in more detail. While preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.
[0027] This utility model provides a flow-blocking and guiding device for reciprocating flow in a plain river network, comprising:
[0028] Multiple guide vanes are installed on both sides of the river channel. The guide vanes are shaped like Tesla valves and all the guide vanes are set in the same direction on the river channel.
[0029] The fixing bases are installed one-to-one with the guide plates, and the fixing bases are set on the bank of the river channel.
[0030] The fixed frame is rotatably mounted on the fixed base at one end, and the other end of the fixed frame is connected to the guide plate.
[0031] Specifically, the device incorporates a Tesla valve-shaped guide plate positioned on the inner side of the riverbank. This unidirectional flow design allows for adaptability to various scenarios requiring flow obstruction and diversion in reciprocating rivers. The Tesla valve is a unidirectional fluid valve with no moving parts, operating primarily based on physical structure and fluid dynamics principles. It achieves unidirectional flow by propelling fluid through its spatial structure. The guide plate is fixed to the riverbank via a mounting base, allowing the water flow to follow the plate's profile and receive guidance. Furthermore, the mounting bracket can rotate the guide plate, altering its guiding effect on the river flow and enabling the conversion between flow diversion and flow obstruction.
[0032] This reciprocating flow obstruction and diversion device for plain river networks is suitable for relatively narrow river channels, generally less than 20m wide. Considering that in plain river network areas, apart from the main stream, other river channels are generally narrow, the application range of this device is relatively wide.
[0033] Optionally, the other end of the mounting bracket is arc-shaped and wraps around the arc surface of the deflector.
[0034] Optionally, the guide plate has multiple grooves on its arc surface along the horizontal direction, and the other end of the fixing frame has a protrusion corresponding to the groove, with the groove and the protrusion engaging with each other.
[0035] Specifically, the connection end between the fixing frame and the guide plate is set as an arc-shaped structure, so that the fixing frame can wrap and fix the guide plate. The fixing frame and the guide plate are respectively provided with protrusions and grooves, and the shapes of the two are compatible. The protrusions can be locked in the grooves to realize the tenon-and-mortise connection between the two. This ensures the fixing strength of the guide plate on the riverbank and also facilitates the disassembly and adjustment of the fixing frame and the guide plate.
[0036] Optionally, multiple grooves arranged along the same horizontal direction form a set of connecting structures, and multiple sets of connecting structures are arranged along the vertical direction on the arc surface of the guide plate.
[0037] Specifically, multiple sets of connecting structures are set on the arc surface of the guide plate. When the water level in the river channel changes, the fixing frame can be combined with different sets of connecting structures to ensure that the water flow always passes around the guide plate.
[0038] In one embodiment, the device can impede flood flow without affecting river flow at low water levels by adjusting the depth of the guide plate at a certain position through interlocking with different connecting structures. This ensures that the flow is impeded at high water levels but unaffected at low water levels. When the device impedes the flow of pollutants that have been mixed at different depths throughout the river channel, the height of the guide plate can be adjusted so that the bottom of the guide plate rests against the riverbed, achieving a complete blockage effect.
[0039] Optionally, a turntable controller is provided on the fixed base along the axial direction, and the turntable controller is connected to the fixed frame through a rotating shaft.
[0040] Specifically, when it is necessary to adjust the orientation of the guide vane in the river channel, the turntable controller is adjusted to drive the rotating shaft and the turntable mounting base to rotate, thus allowing the guide vane to switch between guiding and obstructing functions. The turntable controller can be controlled manually, electrically, or remotely.
[0041] Optionally, a fixing pile is provided at the bottom of the fixing base, and the fixing pile is embedded in the bank of the river channel.
[0042] Optionally, the bottom of the guide plate is provided with water passage holes, and the top of the guide plate is provided with air passage holes.
[0043] Optionally, the deflector can be a hollow shell structure.
[0044] Specifically, the guide plate is fixed to the riverbank by fixing piles on the fixing base. This allows the guide plate to resist the impact of the water flow and guide the water flow. In addition, the guide plate is designed as a hollow shell structure, so that the density of the guide plate material is close to that of the water or the outer skin is thin. When the guide plate is put into the water, the water flows into the interior of the guide plate through the water inlet, and the air inside the guide plate is discharged through the air outlet. This increases the weight of the guide plate and prevents the gravity or buoyancy of the guide plate from exerting a vertical force on the fixing frame, which would affect the connection strength between the guide plate and the fixing frame.
[0045] Alternatively, the guide vanes are staggered on both sides of the river channel bank.
[0046] Specifically, the guide plates are staggered on both sides of the river channel bank. This increases the number of times the water flow can come into contact with the guide plates, so that the water flow in the river channel is fully affected by the guide plates, thereby achieving the effect of obstructing or guiding the flow in the river channel.
[0047] Example
[0048] like Figures 1 to 5 As shown, this utility model provides a flow-blocking and guiding device for reciprocating flow in a plain river network, comprising:
[0049] Multiple guide vanes 1 are set on both sides of the riverbank 9. The guide vanes 1 are in the shape of Tesla valves, and all the guide vanes 1 are set in the same direction on the riverbank 9.
[0050] The fixing seat 6 is set one-to-one with the guide plate 1, and the fixing seat 6 is set on the bank of the river channel.
[0051] The fixed frame 2 is rotatably mounted on the fixed base 6 via the turntable 7 at one end, and the other end of the fixed frame 2 is connected to the guide plate 1.
[0052] In this embodiment, the other end of the fixing frame 2 is arc-shaped and is wrapped around the arc surface of the guide plate 1.
[0053] In this embodiment, a plurality of grooves 3 are provided on the arc surface of the guide plate 1 along the horizontal direction, and a protrusion corresponding to the groove is provided on the other end of the fixing frame 2, and the groove 3 and the protrusion are engaged.
[0054] In this embodiment, multiple grooves 3 arranged along the same horizontal direction form a set of connecting structures, and multiple sets of connecting structures are arranged along the vertical direction on the arc surface of the guide plate 1.
[0055] In this embodiment, a turntable controller 5 is provided on the fixed base 6 along the axial direction, and the turntable controller 5 is connected to the turntable 7 through a rotating shaft.
[0056] In this embodiment, a fixing pile 4 is provided at the bottom of the fixing base 6, and the fixing pile 4 is embedded in the riverbank 9.
[0057] In this embodiment, the bottom of the guide plate 1 is provided with a water passage hole 8, and the top of the guide plate is provided with a vent hole 10.
[0058] In this embodiment, the guide plate 1 is a hollow shell structure.
[0059] In this embodiment, the guide plates 1 are staggered on both sides of the river channel bank 9.
[0060] In summary, the device is staggered on both sides of the river channel bank 9, with all the guide plates 1 on both sides facing the same direction, forming a configuration such as... Figure 4 The structural layout shown allows for control of the water flow direction in the river. When the water flows from left to right, the flow resistance is low, which is the guiding direction; when the water flows from right to left, the flow resistance is high, making it almost impossible to flow, which is the obstructing direction.
[0061] like Figure 5 As shown, suppose the upstream waters of rivers A13 and B14 are polluted. Now, in order to protect area A, then according to... Figure 4 The structural layout includes a flow guide plate 1 between region A and region B. When water from upstream of river A passes through region A, part of the polluted water will flow south downstream, while the other part will flow eastward through river C15. However, when water from upstream of river B14 passes through region B, it cannot flow westward through river C15. This can alleviate the pollution situation in region A.
[0062] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
