Description

Technical Field

[0001] The utility model belongs to the technical field of water conservancy engineering, and specifically relates to a novel multifunctional fishway. Background Art

[0002] Chinese patent CN220468789U discloses a new type of ecological fishway, which discloses technical solutions such as "comprising a main channel and a weir, wherein both sides of the main channel are provided with symmetrical revolving channels for slowing down the flow velocity of water in the main channel, and the weir is arranged in the main channel"; it has technical effects such as "effectively reducing the kinetic energy of water, making it easier for migratory fish to pass through", but the presence of the weir is likely to form eddies, thereby changing the flow characteristics of the water body, causing misunderstanding of fish schools and thus affecting passage, and the building has a single function after the arrangement is completed, and silt is likely to accumulate in the revolving channel during non-fish migration time, destroying the function of the device.

[0003] Although the existing ecological fishways can reduce the kinetic energy of water and ensure easy passage of migratory fish, the setting of a drop-off at the intersection of the main channel and the return channel can effectively reduce the kinetic energy of water, but it is also easy to form eddies and change the flow characteristics of the water body. Most common ecological fishways are S-shaped, and the frequent changes in the direction of the flow channel are not conducive to fish migration. At the same time, most ecological fishways have a single function after construction, and the flow channel is narrow and easy to accumulate silt in the slow flow area during the non-fish migration period, which leads to the loss of fishway function. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the above-mentioned prior art and to provide a new type of multifunctional fishway, which can reduce the water flow velocity in the fishway, induce fish to migrate directly through the fishway to improve the migration efficiency, and at the same time, the modular design can quickly remove the water retaining plate and install column units of different lengths to form a pollution blocking device during the non-fish migration period to intercept water garbage at different depths to achieve the purpose of water purification.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A novel multifunctional fishway comprises a modular waterway installed in a waterway foundation, wherein the waterway is trough-shaped, a plurality of column mounting holes are evenly arranged on the bottom, a plurality of vertical slots are evenly arranged on the side walls, a plurality of water retaining modules are respectively installed on the bottom plates close to the two side walls of the waterway, and the straight area between the water retaining modules on both sides is a migratory channel; the water retaining modules are inclined to the side walls, and the inclination direction is toward the water flow direction, when the water diverted through the water retaining modules re-merges into the migratory channel, the direction of the velocity vector of the water flowing back on both sides is opposite to the direction of the flow velocity vector in the migratory channel.

[0007] Each water retaining module comprises a water retaining unit and a water retaining plate, and the water retaining plate is clamped in the vertical clamping grooves on the column unit and the side wall.

[0008] The water retaining unit comprises a base, a column is fixedly installed on the upper part of the base, a plurality of spring steel bead pins are evenly arranged on the outer peripheral surface of the base, and the column and the base are connected by a plurality of evenly distributed column ribs.

[0009] The upright column is provided with a vertical slot to facilitate the insertion of the water retaining plate.

[0010] The transverse section of the vertical slot is T-shaped, which facilitates the water retaining plate to be clamped.

[0011] The lower part of the vertical slot is at a certain distance from the upper surface of the bottom of the water channel. After the water retaining plate is inserted, there is a certain gap between the bottom of the water retaining plate and the upper surface of the water channel, ensuring that the silt deposited in the slow flow area of ​​the ecological fishway during operation can be cleaned up in time to prevent impact on the function.

[0012] Water retaining units are installed in the column installation holes at the gaps between the water retaining modules on the bottom plate close to the two side walls.

[0013] A groove matching the spring steel ball pin on the outer periphery of the base is provided on the inner side surface of the column mounting hole.

[0014] A novel multifunctional fishway comprises a modular waterway installed in a waterway foundation. The waterway is trough-shaped, with a plurality of vertical slots evenly arranged on the side walls and a plurality of column mounting holes evenly arranged on the bottom. Column units are installed in the column mounting holes.

[0015] The column unit comprises a base, a column is fixedly mounted on the upper part of the base, a plurality of spring steel bead pins are evenly arranged on the outer peripheral surface of the base, and the column and the base are connected by a plurality of evenly distributed column ribs.

[0016] A groove matching the spring steel ball pin on the outer periphery of the base is provided on the inner side surface of the column mounting hole.

[0017] According to the direction of water flow, the column units are divided into multiple groups with increasing heights. (The water flow direction in the article is right in and left out)

[0018] The utility model uses a water retaining plate to divert water entering the water diversion channel from the upstream to form a slow-flow zone; in addition, when the water flow in the slow-flow zone merges into the main channel, the direction of the return water flow on both sides is opposite to the water flow in the water diversion channel, which can significantly reduce the flow velocity in the water diversion channel and help fish migrate. In addition, considering the shortcomings of the single function of the ecological fishway during the non-fish migration period, the water retaining unit and the water retaining plate are removed during this period and replaced with column units of different lengths, which can intercept floating garbage of different depths during the non-fish migration period, and at the same time reduce the sedimentation in the water-blocking slow-flow zone, ensuring the stability of the fishway function.

[0027] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0028] The structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the utility model, so they have no substantial technical significance.

At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the utility model. The change or adjustment of their relative relationship should also be regarded as the scope of the implementation of the utility model without substantial change of the technical content. Example

[0029] like Figure 1-Figure 3 , Figure 6 , Figure 7 As shown, the novel multifunctional fishway is suitable for the migratory period, comprising a modular waterway 2 installed in a waterway foundation 1, wherein the waterway 2 is trough-shaped, a plurality of column mounting holes 3 are evenly arranged on the waterway bottom plate 2-3, a plurality of vertical slots 9-11 and 9-21 are evenly arranged on the waterway side walls 2-1 and 2-2, and five pairs of water retaining modules 4 are respectively installed on the bottom plates near the two side walls 2-1 and 2-2 of the waterway, namely the first to tenth water retaining modules 4-1 to 4-10 , the straight area between the water retaining modules 4-1 to 4-10 on both sides is the migratory channel 5; the water retaining module 4 is inclined to the side walls 2-1 and 2-2 of the water diversion channel, and the inclination direction is toward the direction of water flow. When the water diverted by the water retaining module 4 re-enters the migratory channel 5, the direction of the velocity vector of the water flowing back on both sides is opposite to the direction of the flow velocity vector in the migratory channel 5. The installation direction of the water retaining module 4 needs to be kept consistent to ensure that the effect of slowing down the flow velocity in the migratory channel 5 is achieved.

[0030] Each water retaining module 4 includes a water retaining unit 8 and a water retaining plate 9, and the water retaining plate 9 is clamped in the vertical clamping grooves on the water retaining unit 8 and the side walls 2-1 and 2-2 of the water diversion channel. The water retaining unit 8 is a stainless steel structure as a whole, including a base 7-3, and a column 7-1 is welded and installed on the upper part of the base 7-3. Spring steel ball pins 7-4 are evenly arranged on the outer peripheral surface of the base 7-3 to form a quick disassembly and assembly structure, with a total of four groups of spring steel ball pins, namely the first to fourth spring steel ball pins 7-41 to 7-44, and corresponding circular grooves are pre-made in the column mounting holes in the water diversion channel 2 to match the spring steel ball pins 7-4.

[0031] In order to resist the impact force of water flow on the column 7-1, six column ribs 7-2 are installed between the column 7-1 and the base 7-3 for structural reinforcement. In addition, the first to sixth column ribs 7-21 to 7-26 are evenly distributed and installed to prevent stress concentration.

[0032] A total of six groups of corresponding first to sixth water retaining units 8-1 to 8-6 are set up. The first water retaining unit 8-1 cooperates with the groove 9-11 on the side wall 2-2 of the water diversion channel to place the first water retaining plate 9-1; the first water retaining unit 8-1 cooperates with the second water retaining unit 8-2 to place the seventh water retaining plate 9-7, and so on to complete the installation of the water retaining unit 8 and the water retaining plate 9.

[0033] A vertical slot is provided on the column 7-1 to facilitate the insertion of the water retaining plate 9. The transverse section of the vertical slot is T-shaped, which facilitates the water retaining plate 9 to be stuck. The lower part of the vertical slot is a certain distance from the upper surface of the bottom of the water channel. After the water retaining plate 9 is inserted, there is a certain gap between the bottom of the water retaining plate 9 and the upper surface of the bottom of the water channel, ensuring that the sediment deposited in the slow flow area of ​​the ecological fishway during operation can be cleaned in time to prevent the function from being affected.

[0034] The cooperation between the water retaining unit 8 and the water retaining plate 9 can be further expanded according to the actual local conditions, and the first to sixth water retaining units 8-1 to 8-6 and the first to seventh water retaining plates 9-1 to 9-7 can increase the water retaining area to further slow down the flow rate in the water diversion channel 2.

[0035] Water retaining units 8 are installed in the column mounting holes 3 at the gaps between the multiple groups of water retaining modules 4 on the bottom plate close to the two side walls of the water diversion channel.

[0036] Referring to the principle of the Tesla valve, the water flow in the migratory channel 5 without bends is relatively smooth. When the water diverted by the water retaining module 4 re-enters the migratory channel 5, the direction of the velocity vector of the water flowing back on both sides is opposite to the direction of the flow velocity vector in the migratory channel 5, which can effectively slow down the flow velocity in the main channel. In addition, the flow resistance matrix composed of water retaining units 8 is installed in the column mounting holes 3 in the gaps of multiple groups of water retaining modules 4 on the bottom plate near the two side walls of the water diversion channel, which can further reduce the water flow velocity in the main channel. Example

[0037] like Figure 4-Figure 7 As shown, the novel multifunctional fishway is suitable for the non-migratory period, and includes a modular waterway 2 installed in the waterway foundation 1. The waterway 2 is trough-shaped, and a number of vertical slots are evenly arranged on the side walls 2-1 and 2-2 of the waterway. A plurality of column mounting holes 3 are evenly arranged on the bottom of the waterway, and column units 7 are installed in the column mounting holes 3 to form a pollution blocking module 6. Since the fish migration period is generally short, the current ecological fishway has the disadvantage of being unusable during the non-migratory period, and due to the existence of the slow flow area, it is easy to silt up here, resulting in the loss of the function of the fishway during the migration period. A pollution blocking module 6 is set, and six groups of pollution blocking modules 6-1 to 6-6 of different lengths are installed in the waterway. After installation, a blocking zone can be formed at different water depths to ensure the interception of floating garbage in different water depths, further improve the utilization rate of the ecological fishway, and prevent siltation.

[0038] The column unit 7 is a stainless steel structure as a whole, including a base 7-3, and a column 7-1 is welded and installed on the upper part of the base 7-3. Spring steel bead pins 7-4 are evenly arranged on the outer circumference of the base 7-3 to form a quick disassembly structure, with a total of four groups of spring steel bead pins, namely the first to fourth spring steel bead pins 7-41 to 7-44, and corresponding circular grooves are pre-made in the column installation holes in the water diversion channel 2 to match the spring steel bead pins 7-4.

[0039] In order to resist the impact force of water flow on the column 7-1, six column ribs 7-2 are installed between the column 7-1 and the base 7-3 for structural reinforcement. In addition, the first to sixth column ribs 7-21 to 7-26 are evenly distributed and installed to prevent stress concentration.

[0040] According to the direction of water flow, the column units 7 are divided into multiple groups with increasing heights (the water flow direction in the text is right in and left out). According to the actual local conditions, different lengths of the interception modules 6 are used to improve the interception efficiency. If the floating garbage intercepted by the interception module 6 is entangled with the column unit 7, it needs to be processed regularly.

[0041] Although the above describes the specific implementation methods of the utility model in combination with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. Technical personnel in the relevant field should understand that on the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
