Description

Technical Field

[0001] This utility model relates to the field of water diversion and irrigation engineering technology, specifically to a water flow regulation device for a riverbed system. Background Technology

[0002] Currently, natural water flows originating from high-altitude areas are typically treated (e.g., sedimentation, flow rate regulation) so that the water flow (e.g., water quality and flow rate) can meet the irrigation requirements of downstream areas.

[0003] In the prior art, the invention patent with application publication number CN102107991A discloses "An Ecological Purification System for Decentralized Domestic Sewage in Mountainous Villages and Towns", which includes: a natural confluence and ditch sedimentation tank subsystem (hereinafter referred to as sedimentation system), a flood and sewage diversion subsystem (hereinafter referred to as diversion system), and a ditch vegetation interception subsystem (hereinafter referred to as speed regulation system).

[0004] The sedimentation system includes sedimentation tanks built at equal intervals in the natural confluence channel. The sedimentation tanks are pre-filled with filler material. When water flows through the natural confluence channel, the sedimentation tanks can initially adsorb the sediment, thereby achieving the purpose of initial sedimentation.

[0005] The diversion system includes a diversion channel, a filter screen installed at the lower end of the diversion channel, and flood discharge channels installed at both ends of the diversion channel. When water flows from the sedimentation system to the diversion channel, the filter screen at the bottom of the diversion channel can achieve secondary sedimentation, and the flood discharge channels at both ends of the diversion channel can achieve flood discharge of the water flow (that is, the water flow can pass through the filter screen at the bottom of the diversion channel and also flow into the flood discharge channels at both ends of the diversion channel, thereby achieving water flow regulation).

[0006] The speed control system includes plants (e.g., vines, herbaceous dwarf plants, tall plants) and small dams, which are spaced between the plants. The use of these plants and small dams can reduce the water flow rate.

[0007] However, firstly, although the sedimentation system and the diversion system can purify water quality through sedimentation twice, the flow regulation system may introduce new floating debris (e.g., branches and other debris brought in by the water flow impacting the plants). Secondly, the vegetation in the flow regulation system will be damaged after long-term impact from the water flow, meaning that the vegetation cannot effectively reduce the water flow rate. In summary, the existing solutions have low efficiency in water purification and flow regulation.

[0008] Therefore, there is an urgent need for a water flow regulation device for riverbed systems, which can greatly improve the efficiency of water purification and water flow regulation. Utility Model Content

[0009] To address the aforementioned technical problems, this utility model provides a water flow regulation device for riverbed systems. Firstly, because it incorporates a float-blocking mechanism, a sedimentation mechanism, and a speed-regulating mechanism, the water flow has already been purified by the float-blocking and sedimentation mechanisms when the speed-regulating mechanism adjusts the flow rate; that is, no new floating debris is introduced during the operation of the speed-regulating mechanism. Secondly, because the speed-regulating mechanism itself is a stable gabion structure (compared to the vegetation used in existing speed-regulating mechanisms, the gabions in this utility model are less susceptible to water flow impact), it can effectively reduce the water flow rate. Furthermore, the specific dimensions of the gabions in the speed-regulating mechanism of this utility model can significantly reduce material consumption (i.e., save costs).

[0010] This utility model provides a water flow regulation device for a riverbed system, characterized in that it includes: a float-blocking mechanism for intercepting floating objects arranged sequentially in the river channel; a sedimentation mechanism for settling sediment in the river downstream of the float-blocking mechanism; a diversion mechanism for controlling the flow rate of the river in the river channel arranged downstream of the sedimentation mechanism; and a speed regulation mechanism for adjusting the flow rate of the river in the diversion mechanism.

[0011] The drift-blocking mechanism includes multiple pairs of drift-blocking components connected vertically in sequence. Each pair of drift-blocking components includes two drift-blocking frames arranged vertically symmetrically. Each drift-blocking frame includes multiple regular triangular pyramid hollow structures arranged vertically in sequence.

[0012] The sedimentation mechanism includes sedimentation components disposed on the outer surfaces of the river channel and the riverbank for settling sediment in the river. The sedimentation components include a first sedimentation layer and a second sedimentation layer disposed below the first sedimentation layer.

[0013] The diversion mechanism includes a diversion channel arranged downstream of the first sediment layer along the river channel direction to guide the direction of the river, and a discharge channel arranged at the junction of the river channel and the diversion channel to discharge excess water flow.

[0014] The speed regulating mechanism includes a speed regulating component disposed on the upper surface of the spillway for reducing the river flow. The speed regulating component includes an anti-slip gabion, an anti-scour gabion, and two regulating gabions arranged sequentially from bottom to top. The anti-slip gabion, the anti-scour gabion, and the regulating gabion are all the same height.

[0015] The anti-slip gabion and the erosion gabion have the same length, and the width of the anti-slip gabion is greater than or equal to the width of the erosion gabion.

[0016] Two regulating gabions are symmetrically arranged at both ends of the erosion-resistant gabion with the river channel direction as the axis. The length of the regulating gabion is less than the length of the erosion-resistant gabion, and the width of the regulating gabion is less than the width of the erosion-resistant gabion.

[0017] The above-mentioned water flow regulation device for a riverbed system is characterized in that: the edge length of the hollow triangular pyramid structure is 4.5m.

[0018] The above-mentioned riverbed system water flow regulation device is characterized in that: it further includes a seepage prevention component disposed on the lower surface of the second sediment layer for preventing water infiltration; the seepage prevention component includes a first seepage prevention layer and a second seepage prevention layer disposed on the lower surface of the first seepage prevention layer.

[0019] The above-mentioned riverbed system water flow regulation device is characterized in that: the length of the anti-slip gabion is 50m, the length of the anti-scour gabion is 50m, and the length of the regulating gabion is 12m; the width of the anti-slip gabion is 9m, the width of the anti-scour gabion is 6m, and the width of the regulating gabion is 2m; the height of the anti-slip gabion, the anti-scour gabion, and the regulating gabion is 1m.

[0020] The beneficial effects are analyzed and reasoned as follows:

[0021] In existing technologies, firstly, although sedimentation systems and diversion systems can purify water quality through sedimentation in two stages, the speed regulation system may introduce new floating debris (e.g., branches and other contaminants brought in by water flow impacting plants). Secondly, the vegetation in the speed regulation system will be damaged after long-term water flow impact, meaning the vegetation cannot effectively reduce water flow. In summary, the existing solutions have low efficiency in water purification and flow regulation.

[0022] In the technical solution provided by this utility model, firstly, the drift interception mechanism can intercept floating objects in the river, and the sedimentation mechanism can settle the silt in the river, thereby purifying the river water quality. Secondly, the diversion mechanism can coarsely regulate the water flow in the river channel, and the speed regulation mechanism can finely regulate the water flow, so that the water flow ultimately meets the irrigation requirements of the downstream area.

[0023] Firstly, it is precisely because of the inclusion of a float-blocking mechanism, a sedimentation mechanism, and a speed-regulating mechanism that the water flow has already been purified by the float-blocking and sedimentation mechanisms when the speed-regulating mechanism adjusts the water flow rate. In other words, the speed-regulating mechanism will not introduce new floating objects when it is working.

[0024] This avoids the situation in existing technologies where the speed regulation system may introduce new floating objects (e.g., dirt such as branches and twigs brought by the water flow impacting plants).

[0025] Secondly, precisely because the speed regulating mechanism itself is a stable gabion structure (compared to the speed regulating mechanism in the prior art which is vegetation, the gabion in this utility model is not easily affected by the impact of water flow), it can effectively reduce the water flow rate.

[0026] This avoids the situation in existing technologies where vegetation in speed regulation systems is damaged after being subjected to long-term water flow impact, meaning that the vegetation cannot effectively reduce water flow.

[0027] In summary, the technical solution of this utility model can greatly improve the efficiency of water purification and the efficiency of water flow regulation. Attached Figure Description

[0039] The present invention will now be described in further detail with reference to the embodiments and accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0040] It should be noted that, where there is no conflict, the features of the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the embodiments and accompanying drawings.

[0041] In existing technologies, firstly, although sedimentation systems and diversion systems can purify water quality through two separate sedimentation processes, the speed regulation system may introduce new floating debris (e.g., branches and other contaminants brought in by the water flow impacting plants). Secondly, the vegetation in the speed regulation system will be damaged after long-term water flow impact, meaning the vegetation cannot effectively reduce water flow. In summary, the existing solutions have low efficiency in water purification and water flow regulation.

[0042] Based on this, the present invention provides a water flow regulation device for a riverbed system. Firstly, because it incorporates a float-blocking mechanism, a sedimentation mechanism, and a speed-regulating mechanism, the water flow has already been purified by the float-blocking and sedimentation mechanisms when the speed-regulating mechanism adjusts the water flow rate; that is, no new floating debris is introduced when the speed-regulating mechanism is in operation. Secondly, because the speed-regulating mechanism itself is a stable gabion structure (compared to the vegetation used in existing technologies, the gabions in this invention are less susceptible to water flow impact), it can effectively reduce the water flow rate.

[0043] In summary, the technical solution of this utility model can greatly improve the water purification efficiency and flow regulation efficiency.

[0045] Combination Figures 1 to 7 The present invention provides a water flow regulation device for a riverbed system, comprising: a float-blocking mechanism for intercepting floating objects arranged sequentially in the riverbed; a sedimentation mechanism for settling sediment in the river located downstream of the float-blocking mechanism; a diversion mechanism for controlling the flow of the river in the riverbed located downstream of the sedimentation mechanism; and a speed regulation mechanism for regulating the flow of the river water located in the diversion mechanism.

[0046] The drift-blocking mechanism includes multiple pairs of drift-blocking components connected vertically in sequence. Each pair of drift-blocking components includes two drift-blocking frames arranged vertically symmetrically. Each drift-blocking frame includes multiple regular triangular pyramid hollow structures 1 arranged vertically in sequence.

[0047] The sedimentation mechanism includes sedimentation components for settling sediment in the river, which are installed on the outer surface of the river channel and the riverbank. The sedimentation components include a first sedimentation layer 2 and a second sedimentation layer 3 installed below the first sedimentation layer.

[0048] The diversion mechanism includes a diversion channel 4 set downstream of the first sediment layer 2 along the river channel direction to guide the direction of the river, and a discharge channel 5 set at the junction of the river channel and the diversion channel 4 to discharge excess water flow.

[0049] The speed regulation mechanism includes a speed regulation component for slowing down the river flow, which is set on the upper surface of the spillway 5. The speed regulation component includes an anti-slip gabion 6, an anti-scour gabion 7, and two regulating gabions 8 arranged sequentially from bottom to top. The anti-slip gabion 6, the anti-scour gabion 7, and the regulating gabion 8 are all the same height.

[0050] The anti-slip gabion 6 and the erosion gabion 7 have the same length, and the width of the anti-slip gabion 6 is greater than or equal to the width of the erosion gabion 7.

[0051] Two adjustable gabions 8 are symmetrically arranged at both ends of the erosion-resistant gabion 7 with the river channel direction as the axis. The length of the adjustable gabion 8 is less than the length of the erosion-resistant gabion 7, and the width of the adjustable gabion 8 is less than the width of the erosion-resistant gabion 7.

[0052] The triangular pyramid hollow structure 1 can be composed of three vertical skeletons and six horizontal braces. For example, the diameter of each vertical skeleton can be 30-40cm, and the diameter of each horizontal brace can be 15-20cm, and the material of the vertical skeletons and horizontal braces can be wood.

[0053] The first settling layer 2 can be a gabion cage, and the second settling layer 3 can be gravel placed below the gabion cage.

[0054] Preferably, the gravel can also be placed in a gabion cage, and the two together form a sedimentation component to achieve sedimentation of the silt. The specific placement of the gravel can be selected according to the actual situation.

[0055] After passing through the damming mechanism, sedimentation mechanism, diversion mechanism, and speed regulation mechanism in sequence, the water flow rate in the river can reach 26 to 50 cubic meters per second.

[0056] It should be noted that the lengths of the anti-slip gabion 6, the erosion-resistant gabion 7, and the regulating gabion 8 all refer to the dimensions along the width of the river (i.e., perpendicular to the direction of river flow), while the widths of the anti-slip gabion 6, the erosion-resistant gabion 7, and the regulating gabion 8 all refer to the dimensions along the length of the river (i.e., parallel to the direction of river flow).

[0057] When the anti-slip gabion 6 and the erosion gabion 7 are of the same length, they can stably resist the impact of water flow. The width of the anti-slip gabion 6 is greater than or equal to the width of the erosion gabion 7. That is, if the width of the erosion gabion 7 is less than the width of the anti-slip gabion 6, it is possible to regulate the water flow while saving materials (i.e., reducing the cost of gabions).

[0058] A pair of regulating gabions 8 are symmetrically set at both ends of the anti-erosion gabion 7 to prevent the water flowing through the spillway 5 from washing away the sides of the spillway 5.

[0059] In practice, firstly, when the river flows through the drift-blocking mechanism, the drift-blocking frame, which is made up of several hollow triangular pyramidal structures 1, can intercept floating objects in the river and then flow to the sedimentation mechanism downstream.

[0060] Secondly, when the river flows through the sedimentation mechanism set downstream of the damming mechanism, the water first impacts the riverbank from the river channel, and then flows back from the riverbank to the river channel. Specifically, the backflow process is that the water flows from the high point of the riverbank through the sedimentation components (i.e., the first sedimentation layer 2 and the second sedimentation layer 3 set below the first sedimentation layer 2), and then flows into the river channel, and finally flows to the downstream diversion mechanism.

[0061] Third, when the river flow is directed towards the diversion mechanism downstream of the sedimentation mechanism, it can flow in both the direction of the guide channel 4 and the direction of the spillway 5, thus achieving coarse regulation of the river flow. It is understood that the spillway 5 can handle a flow rate greater than or equal to that of the guide channel 4.

[0062] Understandably, multiple diversion mechanisms can be set up downstream of the sedimentation mechanism, with the specific number of sections designed based on the final water flow meeting the irrigation requirements of the downstream area.

[0063] Fourth, when the river flow direction is set downstream of the diversion mechanism (specifically, the spillway 5), the flow rate of the water flowing through the spillway 5 can be finely adjusted. Specifically, the anti-slip gabion 6, the anti-scouring gabion 7, and the regulating gabion 8 are set in the spillway 5 from bottom to top.

[0064] The beneficial effects are analyzed and reasoned as follows:

[0065] In existing technologies, firstly, although sedimentation systems and diversion systems can purify water quality through sedimentation in two stages, the speed regulation system may introduce new floating debris (e.g., branches and other contaminants brought in by water flow impacting plants). Secondly, the vegetation in the speed regulation system will be damaged after long-term water flow impact, meaning the vegetation cannot effectively reduce water flow. In summary, the existing solutions have low efficiency in water purification and flow regulation.

[0066] In the technical solution provided by this utility model, firstly, the drift interception mechanism can intercept floating objects in the river, and the sedimentation mechanism can settle the silt in the river, thereby purifying the river water quality. Secondly, the diversion mechanism can coarsely regulate the water flow in the river channel, and the speed regulation mechanism can finely regulate the water flow, so that the water flow ultimately meets the irrigation requirements of the downstream area.

[0067] Firstly, it is precisely because of the inclusion of a float-blocking mechanism, a sedimentation mechanism, and a speed-regulating mechanism that the water flow has already been purified by the float-blocking and sedimentation mechanisms when the speed-regulating mechanism adjusts the water flow rate. In other words, the speed-regulating mechanism will not introduce new floating objects when it is working.

[0068] This avoids the situation in existing technologies where the speed regulation system may introduce new floating objects (e.g., dirt such as branches and twigs brought by the water flow impacting plants).

[0069] Secondly, precisely because the speed regulating mechanism itself is a stable gabion structure (compared to the speed regulating mechanism in the prior art which is vegetation, the gabion in this utility model is not easily affected by the impact of water flow), it can effectively reduce the water flow rate.

[0070] This avoids the situation in existing technologies where vegetation in speed regulation systems is damaged after being subjected to long-term water flow impact, meaning that the vegetation cannot effectively reduce water flow.

[0071] In summary, the technical solution of this utility model can greatly improve the efficiency of water purification and the efficiency of water flow regulation.

[0072] In the embodiments described above, a water flow regulation device for a riverbed system was introduced. In another embodiment of this utility model, the specific dimensions of the hollow triangular pyramid structure 1 in the drift-blocking mechanism were introduced.

[0073] For example, the edge length of the hollowed-out triangular pyramid 1 is 4.5m.

[0074] It should be noted that the above-mentioned edge length is only used as an example in this utility model and does not impose any specific limitations on the edge length.

[0075] Understandably, when the edge length is smaller, the gaps in the spliced ​​drift-blocking frame are smaller, which can intercept more small-sized floating objects.

[0076] The specific dimensions of the hollow triangular pyramid structure 1 in the drift-blocking mechanism were described in the embodiments described above. In another embodiment of this utility model, a seepage-proof component is described, which is disposed on the lower surface of the second sediment layer 3.

[0077] For example, it also includes a seepage prevention component disposed on the lower surface of the second sedimentation layer 3 to prevent water from seeping down; the seepage prevention component includes a first seepage prevention layer 9 and a second seepage prevention layer 10 disposed on the lower surface of the first seepage prevention layer.

[0078] Understandably, the impermeable components allow the sedimentation components to be securely mounted on the riverbank surface to perform their sedimentation function. For example, the first impermeable layer 9 can be a geomembrane, and the second impermeable layer 10 can be clay.

[0079] The embodiments described above introduce an anti-seepage component installed on the lower surface of the second sedimentation layer 3. In another embodiment of this invention, the specific dimensions of the anti-slip gabion 6, the erosion-resistant gabion 7, and the adjustable gabion 8 are described.

[0080] For example, the length of anti-slip gabion 6 is 50m, the length of anti-impact gabion 7 is 50m, and the length of regulating gabion 8 is 12m; the width of anti-slip gabion 6 is 9m, the width of anti-impact gabion 7 is 6m, and the width of regulating gabion 8 is 2m; the height of anti-slip gabion 6, anti-impact gabion 7, and regulating gabion 8 is 1m.

[0081] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0082] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
