Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to a novel multifunctional fishway. Background Technology

[0002] Fish passages are channels for fish to migrate through. Remedial measures taken when human activities damage fish migration channels are usually done by building artificial water channels on sluice gates or dams to protect the habits of fish.

[0003] Chinese utility model patent CN222206248U discloses a novel multifunctional fishway, comprising a modular water intake channel installed in a waterway foundation. The water intake channel is trough-shaped, with multiple column mounting holes evenly distributed at its bottom and several vertical slots evenly distributed on its side walls. Several water-blocking modules are installed on the bottom plates near the side walls of the water intake channel. Each water-blocking module includes a water-blocking unit and a water-blocking plate. The water-blocking plate is engaged in the vertical slots on the column unit and side walls. The water-blocking unit includes a base, with a column fixedly installed on the upper part of the base. Several spring steel ball pins are evenly distributed on the outer circumference of the base. The water-blocking plate diverts water entering the water intake channel from upstream, forming a slow-flow zone. Furthermore, when the water in the slow-flow zone merges into the main channel, the direction of the return flow on both sides is opposite to the water flow in the water intake channel, which can significantly reduce the water flow velocity in the water intake channel and help fish migrate. During non-fish migration periods, the water-blocking units and baffles are removed and replaced with column units of different lengths, which can intercept floating debris at different depths during non-fish migration periods.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: During the switching process between the flood season and the non-flood season, it is necessary to switch several column units and water baffles one by one. This process is not only cumbersome, but also labor-intensive, bringing additional physical burden to the staff. Utility Model Content

[0005] In order to at least partially solve or alleviate the above problems, this utility model provides a novel multifunctional fishway.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a novel multifunctional fishway, including a water intake channel, wherein several sets of water-blocking components are spaced apart along the length of the water intake channel, each set consisting of two water-blocking components, which are respectively set on opposite inner walls of the water intake channel and arranged symmetrically. Each water-blocking component includes a mounting frame, on which a water-blocking plate is rotatably mounted. A column is set on the top of the water-blocking plate on the side away from the mounting frame. A connecting rod is commonly set on the column of the water-blocking component on the same side of the water intake channel. A rotating hole is vertically opened on the connecting rod, and the column is rotatably connected to the corresponding rotating hole. Filter plates are rotatably mounted on opposite inner walls of the water intake channel. Two control components are provided on the water intake channel for adjusting the positions of adjacent connecting rods and filter plates.

[0007] By adopting the above technical solution, which includes a water-blocking component, connecting rod, and control component, the position of the connecting rod is adjusted by the control component when switching between flood season and non-flood season. This causes several water-blocking plates to rotate until they are parallel to the inner wall of the water intake channel, thus losing their effect of restricting water flow. Simultaneously, the control component controls the rotation of the filter plates, causing two filter plates to block the interior of the water intake channel, filtering impurities from the water flow during the non-flood season. Switching between flood season and non-flood season is convenient and reduces the workload of staff.

[0008] Furthermore, the control component includes a first sliding groove disposed on the water intake channel, a sliding seat slidably disposed in the first sliding groove, a horizontal sliding hole opened on the sliding seat, a control rod slidably disposed in the sliding hole, one end of the control rod being connected to a connecting rod, two fixing holes spaced apart on the control rod, a screw hole vertically opened on the sliding seat, the screw hole communicating with the sliding hole, a first threaded rod spirally disposed in the screw hole, a rotating handle disposed at the upper end of the first threaded rod, and a linkage unit disposed on the water intake channel for driving the filter plate to rotate when the sliding seat slides.

[0009] By adopting the above technical solution, a first slide groove, a sliding seat, a control rod, a first threaded rod, and a rotating handle are set. The two fixing holes are concentric with the screw holes when the baffle is in operation and closed, respectively. When the position of the connecting rod needs to be adjusted, the control rod is moved, thereby driving the connecting rod to move. Then, the rotating handle is turned to drive the first threaded rod to descend, so that the lower end of the first threaded rod extends into the fixing hole, fixing the control rod, thereby fixing the connecting rod and the baffle.

[0010] Furthermore, a fixed shaft is vertically arranged on one side of the filter plate, and connecting blocks are provided at both the upper and lower ends of the fixed shaft. The connecting blocks are connected to the inner wall of the water inlet channel. The linkage unit includes a second sliding groove arranged on the water inlet channel. A rack is slidably arranged in the second sliding groove. One end of the rack is connected to a sliding seat. A rotating shaft is vertically rotatably arranged on the water inlet channel. A first gear and a second gear are fixedly sleeved on the rotating shaft. The first gear meshes with the rack. A third gear is arranged at the upper end of the fixed shaft through the connecting block. The third gear meshes with the second gear.

[0011] By adopting the above technical solution, a fixed shaft, a second slide groove, a rack, a first gear, a second gear, and a third gear are set. When the sliding seat slides, it drives the rack to slide, thereby causing the first gear, the second gear, and the rotating shaft to rotate, which in turn drives the third gear and the fixed shaft to rotate, thus causing the filter plate to rotate.

[0012] Furthermore, triangular blocks are provided at the bottom of the water channel between each set of water-blocking components.

[0013] By adopting the above technical solution and setting up a triangular block, when the water baffle is activated, the lower side of the water baffle contacts the side of the triangular block, and the triangular block provides support for the water baffle, thereby enhancing the stability of the water baffle.

[0014] Furthermore, the baffle plate is provided with a receiving groove, a sliding plate is slidably disposed in the receiving groove, and an adjustment component for adjusting the position of the sliding plate is provided on the top of the baffle plate.

[0015] By adopting the above technical solution, a receiving tank, a sliding plate, and an adjustment component are set up. The position of the sliding plate is adjusted by the adjustment component, so that the sliding plate slides out from the opening of the receiving tank, thereby changing the adjustment effect on the water flow.

[0016] Furthermore, the top of the baffle plate is provided with a strip groove, which is connected to the receiving groove. The top of the baffle plate is provided with a plurality of circular grooves at intervals, which are connected to the strip groove and the receiving groove. The adjusting component includes a threaded hole on the top of the sliding plate. A second threaded rod is spirally arranged in the threaded hole. The diameter of the second threaded rod is smaller than the width of the strip groove. A circular block is provided at the upper end of the second threaded rod. The diameter of the circular block is the same as the diameter of the circular groove. A control handle is provided on the top of the circular block.

[0017] By adopting the above technical solution, a strip groove, a circular groove, a second threaded rod, and a circular block are set. When adjusting the position of the sliding plate, first turn the control handle to drive the second threaded rod and the circular block to rise, so that the bottom of the circular block is higher than the top surface of the baffle plate. Then move the control handle to drive the sliding plate to slide, and then turn the control handle to drive the circular block to fall, so that the circular block is stuck in the corresponding circular groove, thereby fixing the position of the sliding plate.

[0018] Furthermore, one of the filter plates has a pin hole on its top, and the other filter plate has a fixing block on its top, with a pin that matches the pin hole slidably mounted on the fixing block.

[0019] By adopting the above technical solution, a pin hole, a fixing block, and a pin are set. After the filter plate is activated, the pin is inserted into the pin hole to connect the two filter plates and ensure the stability of the filter plates.

[0020] In summary, this utility model has the following beneficial effects: By incorporating a water-blocking component, a connecting rod, and a control component, when switching between flood and non-flood seasons, the control component adjusts the position of the connecting rod, thereby rotating several water-blocking plates until they are parallel to the inner wall of the water intake channel, thus losing their effect of restricting water flow. Simultaneously, the control component controls the rotation of the filter plates, causing two filter plates to block the interior of the water intake channel, filtering impurities in the water flow during non-flood seasons. Switching between flood and non-flood seasons is convenient and reduces the labor intensity of workers. Attached Figure Description

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0029] like Figure 1-6As shown in the embodiment of this application, a novel multifunctional fishway is disclosed, including a water inlet channel 10, a water-blocking component 20, and a control component 30. The water inlet channel 10 is trough-shaped. Several groups of water-blocking components 20 are spaced apart along the length of the water inlet channel 10. Each group consists of two water-blocking components 20, which are respectively disposed on opposite inner walls of the water inlet channel 10 and arranged symmetrically. The water-blocking component 20 includes a mounting frame 21, on which a water-blocking plate 22 is vertically rotatably mounted (the water-blocking plate 22 is rotatably mounted around the vertical center of the mounting frame 21). (Arranged for axial rotation), a column 23 is installed on the top of the side of the baffle plate 22 away from the mounting frame 21. A connecting rod 24 is installed on the column 23 of the baffle assembly 20 on the same side of the water diversion channel 10. The connecting rod 24 has a vertical rotating hole, and the column 23 is rotatably connected to the corresponding rotating hole (the column 23 is used to insert the rotating hole of the connecting rod 24). When the connecting rod 24 moves, it drives several baffle plates 22 to move synchronously. Each baffle 22 rotates relative to the vertical central axis to adjust the tilt angle along the water flow direction. Filter plates 25 are vertically rotatably installed on the inner walls of opposite sides of the water diversion channel 10. The filter plates 25 are located on the upstream side of the baffle 22. There are two control components 30, which respectively adjust the swing position of the adjacent connecting rod 24 and filter plate 25. When activated, the baffle plates 22 are tilted within the water intake channel 10, diverting water entering from upstream and creating a slow-flow zone. Furthermore, when the water from this slow-flow zone merges into the main channel, the direction of the backflow on both sides is opposite to the flow in the water intake channel 10, significantly reducing the water velocity and aiding fish migration. When switching between the flood season and non-flood season, the position of the connecting rod 24 is adjusted by the control component 30, causing several baffle plates 22 to rotate until they are parallel to the inner wall of the water intake channel 10, thus losing their flow-limiting effect. Simultaneously, the control component 30 controls the rotation of the filter plates 25, causing them to block the interior of the water intake channel 10, filtering impurities from the water flow during the non-flood season. Switching between the flood season and non-flood season is convenient and reduces the workload of staff.

[0030] Specifically, the baffle plate 22 has a receiving groove 221. The opening of the receiving groove 221 is located on the side of the mounting plate away from the mounting bracket 21. A sliding plate 222 is slidably disposed in the receiving groove 221. An adjustment component 60 is provided on the top of the baffle plate 22 to adjust the position of the sliding plate 222. By adjusting the position of the sliding plate 222 through the adjustment component 60, the sliding plate 222 slides out from the opening of the receiving groove 221, thereby changing the regulation effect on the water flow (the water-blocking width is adjusted by setting the sliding length of the sliding plate 222 along the width direction of the baffle plate 22, thereby changing the regulation effect on the water flow). The top of the baffle plate 22 has a strip groove 223, which communicates with the receiving groove 221. The top of the baffle plate 22 also has several circular grooves 224 spaced apart, which communicate with both the strip groove 223 and the receiving groove 221. The adjusting assembly 60 includes a threaded hole on the top of the sliding plate 222. A second threaded rod 61 is spirally arranged inside the threaded hole. The diameter of the second threaded rod 61 is smaller than the width of the strip groove 223. A circular block 62 is provided at the upper end of the second threaded rod 61. The diameter of the circular block 62 is... With the same diameter as the circular groove 224, the top of the circular block 62 is provided with a control handle 63. When adjusting the position of the sliding plate 222, first rotate the control handle 63 to drive the second threaded rod 61 and the circular block 62 to rise, so that the bottom of the circular block 62 is higher than the top surface of the baffle plate 22. Then move the control handle 63 to drive the sliding plate 222 to slide. Then rotate the control handle 63 to drive the circular block 62 to fall, so that the circular block 62 is inserted into the corresponding circular groove 224, thereby fixing the position of the sliding plate 222.

[0031] At the bottom of the water channel 10, triangular blocks 11 are provided between each group of water-blocking components 20. When the water-blocking plate 22 is activated, it is tilted in the direction of water flow. When the water-blocking plate 22 is activated, the lower side of the water-blocking plate 22 contacts the side of the triangular block 11, and the triangular block 11 provides support for the water-blocking plate 22, enhancing its stability. One filter plate 25 has a pin hole 251 at its top, and the other filter plate 25 has a fixing block 252 at its top. A pin 253 that matches the pin hole 251 is vertically slidably mounted on the fixing block 252. After the filter plate 25 is activated, the pin 253 is inserted into the pin hole 251, connecting the two filter plates 25 and ensuring the stability of the filter plates 25.

[0032] In setup, the control component 30 includes a first slide groove 31 on the water channel 10. A sliding seat 32 is slidably disposed within the first slide groove 31. A horizontal sliding hole is provided on the sliding seat 32, and a control rod 33 is horizontally slidably disposed within the sliding hole. One end of the control rod 33 is connected to the connecting rod 24. Two fixing holes 34 are spaced apart on the control rod 33, and a screw hole is vertically provided on the sliding seat 32. The two fixing holes 34 are concentric with the screw hole when the baffle plate 22 is open and closed, respectively. The screw hole communicates with the slide hole, and a first threaded rod 35 is spirally disposed within the screw hole. A rotating handle 36 is provided at the upper end of the first threaded rod 35. When the position of the connecting rod 24 needs to be adjusted, the control rod 33 is moved, thereby moving the connecting rod 24. Then, the rotating handle 36 is rotated to lower the first threaded rod 35, so that the lower end of the first threaded rod 35 extends into the fixing hole 34, fixing the control rod 33, thereby fixing the connecting rod 24 and the baffle plate 22. A linkage unit 40 is provided on the water channel 10 to drive the filter plate 25 to rotate when the sliding seat 32 slides.

[0033] In the specific configuration, a fixed shaft 50 is vertically arranged on one side of the filter plate 25. Connecting blocks 51 are provided at both the upper and lower ends of the fixed shaft 50. The connecting blocks 51 are connected to the inner wall of the water channel 10. The linkage unit 40 includes a second sliding groove 41 arranged on the water channel 10. A rack 42 is slidably arranged in the second sliding groove 41. One end of the rack 42 is connected to a sliding seat 32, allowing the sliding seat 32 and the rack 42 to slide synchronously. A rotating shaft 43 is vertically rotatably arranged on the water channel 10. A first gear 44 and a second gear 45 are fixedly sleeved on the rotating shaft 43. The first gear 44 meshes with the rack 42. A third gear 46 is arranged at the upper end of the fixed shaft 50, passing through the connecting block 51. The third gear 46 meshes with the second gear 45. When the sliding seat 32 slides, it drives the rack 42 to slide, thereby causing the first gear 44, the second gear 45, and the rotating shaft 43 to rotate, which in turn drives the third gear 46 and the fixed shaft 50 to rotate, thus causing the filter plate 25 to rotate. After the two filter plates 25 are activated, their surfaces are coplanar, and the side of the filter plate 25 away from the fixed shaft 50 is in contact, ensuring the interception effect of debris. The filter plates 25 filter debris in the water inlet channel 10. When too much debris is attached to the filter plates 25, the staff will clean them.

[0034] The operating principle of this novel multifunctional fishway in this embodiment is as follows:

[0035] When switching the device between the flood season and the non-flood season, first turn the handle 36 to drive the first threaded rod 35 to rise and release the limit constraint. Then, apply force to move the connecting rod 24, the control rod 33, and the sliding seat 32 so that the baffle plate 22 is parallel to the inner wall of the water channel 10 and loses its effect of restricting the water flow. Then turn the handle 36 to drive the first threaded rod 35 to fall and insert the limit, so that the lower end of the first threaded rod 35 extends into the fixing hole 34 and fixes the control rod 33, thereby fixing the connecting rod 24 and the baffle plate 22.

[0036] At the same time, when the sliding seat 32 slides, it drives the rack 42 to slide, thereby causing the first gear 44, the second gear 45, and the rotating shaft 43 to rotate, which in turn drives the third gear 46 and the fixed shaft 50 to rotate, thereby causing the filter plate 25 to rotate. Then, the pin 253 is inserted into the pin hole 251 to connect the two filter plates 25 and ensure the stability of the filter plate 25.

[0037] In one specific embodiment, the first gear has a diameter of 35 cm and a circumference of approximately 105 cm; the second gear has a diameter of 17 cm and a circumference of approximately 51 cm; the third gear has a diameter of 35 cm and a circumference of approximately 105 cm; if the rack moves 40 cm, the filter plate can rotate one-quarter of its length.

[0038] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
