Description

Technical Field

[0001] This utility model relates to the field of water conservancy technology, specifically to a stilling pool with a diversion and energy dissipation structure. Background Technology

[0002] Stilling basins are energy dissipation facilities that induce bottom flow hydraulic jumps downstream of spillway structures. They can quickly transform rapid downstream flow into slow flow, making them an effective and economical energy dissipation facility. Most existing stilling basins utilize the hydraulic jump phenomenon for energy dissipation along the entire water flow, which has limited energy dissipation methods and generally poor results. Moreover, during the energy dissipation process, the water flow carries away some impurities and gravel, which accumulate in the stilling basin. If this accumulation is not cleaned over time, a large amount of material will be washed downstream, affecting water quality. Therefore, there is an urgent need for a stilling basin with a diversion energy dissipation structure. Utility Model Content

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] like Figures 1-4 As shown, the specific embodiment adopts the following technical solution: it includes a pool bottom 1, a tail sill 2, an inclined ramp 3 and a side guard plate 4. The inclined ramp 3 and the tail sill 2 are respectively provided on the upper left and right sides of the pool bottom 1. The front and rear sides between the inclined ramp 3 and the tail sill 2 are provided with side guard plates 4, and the side guard plates 4 are located above the pool bottom 1.

[0027] It also includes:

[0028] An inclined fish-scale slope 5 is located on the upper part of the inclined gentle slope 3. Several water-blocking edges 6 are fixedly installed on the inclined fish-scale slope 5, and convenient cleaning components 12 are provided on the water-blocking edges 6.

[0029] Diversion baffles 7, there are several diversion baffles 7, all of which are fixedly installed on the upper part of the pool bottom 1, and the left and right sides of the diversion baffles 7 are respectively connected to the inclined gentle slope 3 and the tail sill 2.

[0030] The No. 1 sill bar 8, there are several No. 1 sill bars 8, which are respectively fixedly installed on the upper part of the pool bottom 1 at the left and right sides of the diversion baffle 7. The diversion baffle 7 has a No. 1 flow port 9 at the left side of the No. 1 sill bar 8.

[0031] The second sill bar 10, of which there are several, is fixedly installed on the left and right side walls of several diversion baffles 7. A second flow port 11 is opened on the left side of the second sill bar 10 on the diversion baffle 7. The first sill bars 8 on both sides of the diversion baffle 7 are staggered and the second sill bars 10 on both sides of the diversion baffle 7 are staggered, which can realize staggered flow between the diversions on both sides of the diversion baffle 7, making the flow of each diversion more turbulent and improving the energy dissipation effect on the water flow.

[0032] The convenient cleaning component 12 includes;

[0033] A baffle 12-1 is movably disposed within a cleaning port 18 opened on the water-blocking edge 6. A sealing strip 15 is fixedly installed in a groove opened on the side wall of the baffle 12-1, and the sealing strip 15 is set in contact with the inner wall of the cleaning port 18. The sealing strip 15 can improve the sealing between the baffle 12-1 and the cleaning port 18, preventing water from flowing from the gap between the baffle 12-1 and the cleaning port 18 when the baffle 12-1 closes the cleaning port 18. The right side wall of the baffle 12-1 A control rod 12-2 is fixedly installed on the upper part, and the control rod 12-2 is movably inserted into the vertical groove 13 opened on the front side wall of the water-blocking edge 6. A threaded locking rod 16 is inserted into the control rod 12-2 by threaded rotation. One end of the threaded locking rod 16 passes through the control rod 12-2 and the baffle 12-1 and then abuts against the inner wall of the cleaning port 18. The end of the threaded locking rod 16 can generate a huge friction force with the inner wall of the cleaning port 18 to limit the baffle 12-1 in the cleaning port 18.

[0034] Hook 12-3, there are three hooks 12-3, which are respectively fixedly installed on the front side wall of the water-blocking side 6 at the left and right sides and below the cleaning port 18. Hook 12-4 is fixedly installed on the front side wall of the baffle 12-1.

[0035] The cleaning net bag 12-5 is located on the front side of the water-blocking edge 6. The opening of the cleaning net bag 12-5 has four mounting holes 14, which are respectively matched with the first hook 12-3 and the second hook 12-4. The upper end of the first hook 12-3 and the second hook 12-4 is fixedly provided with an anti-detachment block 17, which is spherical in structure. The anti-detachment block 17 not only prevents the cleaning net bag 12-5 from easily falling off the first hook 12-3 and the second hook 12-4, but also improves the ease of installation of the cleaning net bag 12-5 on the first hook 12-3 and the second hook 12-4 due to its spherical structure.

[0036] When using this utility model, the water flow generates multiple hydraulic jumps as it passes through the inclined fish-scale slope 5 and the water-blocking edge 6. This not only achieves multiple energy dissipation of the water flow but also intercepts impurities and gravel. Subsequently, the energy-dissipated water flow will form several diversions through several diversion baffles 7. As the diversions continue to flow to the right, the cooperation of the first sill bar 8 and the second sill bar 10 not only allows for another hydraulic jump to dissipate energy but also allows the diversions on one side to flow to the diversions on the other side through the first flow port 9 and the second flow port 11. At this time, the water flowing out from the first flow port 9 and the second flow port 11 will impact the diversions, making the diversions more turbulent and thus achieving a better energy dissipation effect.

[0037] When it is necessary to clean up the intercepted impurities and gravel, loosen the threaded locking rod 16 so that one end disengages from the inner wall of the cleaning port 18. Then, move the control rod 12-2 upwards. The control rod 12-2 moves the baffle 12-1 upwards, and the baffle 12-1 moves the second hook 12-4 upwards, causing the opening of the cleaning net bag 12-5 and the cleaning port 18 to open simultaneously. At this time, under the influence of the water flow, the impurities and gravel intercepted by the water-blocking edge 6 can be carried through the cleaning port 18 and enter the cleaning net bag 12-5 for collection. After the intercepted impurities and gravel are collected, move the baffle 12-1 downwards to close the cleaning port 18, and the opening of the cleaning mesh bag 12-5 will also close. Then tighten the threaded locking rod 16, so that one end of the threaded locking rod 16 generates a huge friction force with the bottom of the inner wall of the cleaning port 18, which limits the baffle 12-1. After that, the cleaning mesh bag 12-5 can be moved upwards, so that the four mounting holes 14 can be removed from the first hook 12-3 and the second hook 12-4 respectively. Remove the cleaning mesh bag 12-5 and proceed with the subsequent processing of the collected impurities and gravel.

[0038] Compared with the prior art, the beneficial effects of this utility model are:

[0039] 1. By combining the inclined fish scale slope 5, the water-blocking edge 6 and the convenient cleaning component 12, not only can multiple water jumps and energy dissipation of water flow be achieved, but impurities and gravel can also be intercepted and cleaned, thereby improving the downstream water quality.

[0040] 2. Through the coordination of the diversion baffle 7, No. 1 retaining bar 8, No. 1 flow outlet 9, No. 2 retaining bar 10 and No. 2 flow outlet 11, not only can the water flow be diverted and energy dissipated, but the diversions can also flow and impact each other, so that the diversions can fully rub and turbulently move, thereby improving the energy dissipation effect.

[0041] 3. By staggering the distribution of No. 1 retaining bars 8 and No. 2 retaining bars 10 on both sides of the diversion baffle 7, the flow of each diversion can be made more disordered, thereby further improving the energy dissipation effect on the water flow.

[0042] 4. The anti-detachment block 17 not only prevents the cleaning net bag 12-5 from easily falling off the first hook 12-3 and the second hook 12-4, but also improves the ease of installation of the cleaning net bag 12-5 on the first hook 12-3 and the second hook 12-4 through the spherical structure of the anti-detachment block 17.

[0043] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
