The top for supportting cavity 23, is provided with water hole 31 (as shown in Figure 9), when hydraulic pressure is excessive, runner lid in the bottom of round elastic slice 3
Plate 2 moves up, and round elastic slice 3 deforms therewith, and the presence of round elastic slice 3 makes the retard motion of flow passage cover plate 2, is unlikely to
Keep flow channel depth excessive and causes flow excessive.As shown in Figure 11, Figure 12, the top for adjusting cavity 7 is sealed end, bottom is to open
Mouth end, the outer wall for adjusting the inner wall and 4 upper cavity of pedestal of 7 lower part of cavity are fastened and connected, the edge on the side wall for adjusting cavity 7
It has been provided at circumferentially spaced multiple water outlets 71.Scraping blade cover board 5 includes the cover board 51 for being placed in 4 top of pedestal, in the week of cover board 51
Be arranged at intervals with multiple scraping blades 52 (as shown in Figure 10) to edge, each scraping blade 52 from each water outlet 71 it is corresponding stretch out and with water outlet
Mouth 71 is slidably connected.By the moving up and down on 71 side wall of water outlet of scraping blade 52, the big of 71 water yield of water outlet can be adjusted
It is small, while dirt being prevented to be attached on the wall surface of 71 side wall of water outlet.The top for adjusting cavity 7 is arranged in elastic support member 6
Between scraping blade cover board 5, when water flow is excessive, under the action of elastic support member 6, scraping blade cover board 5 can be obstructed to go out
It now significantly moves, further increases the uniformity of water outlet.The top for exporting cavity 8 is sealed end, bottom is open end, outlet
The inner wall of 8 bottom of cavity and the outer wall of 4 lower chamber of pedestal are fastened and connected, and in outlet, the top of cavity 8 is provided with water outlet
81 (as shown in figure 13).
In above-described embodiment, the top edge of import water-guiding element 1 is provided with annular convex platform 14, for guaranteeing runner most
Small depth.
In above-described embodiment, between the inner wall of 4 lower chamber of outer wall and pedestal of import water-guiding element 1,4 lower chamber of pedestal
Outer wall and export cavity 8 bottom interior wall between and 4 upper cavity of pedestal outer wall and adjust cavity 7 lower inner wall between
It is connected through a screw thread.
In above-described embodiment, as shown in figs. 4 and 6, at the top for the flow passage cover plate 2 being located in support cavity 23 close to stream
The position of road outlet 22 is provided with boss 24, blocks for preventing round elastic slice 3 from deforming senior general's runner exit 22.
In above-described embodiment, as shown in fig. 7, the position of conduction hole 42 is provided with boss 43 in the bottom of partition 41,
For preventing in the case where hydraulic pressure is excessive conduction hole 42 to be blocked by deformed round elastic slice 3.
In above-described embodiment, elastic support member 6 is spring, is provided at the top of scraping blade cover board 5 for fixed spring
The annular groove 53 (as shown in Figure 10) of one end.It is provided in the top inner wall for adjusting cavity 7 for the fixed spring other end
Annular groove 72 (as shown in figure 12).
In above-described embodiment, as shown in Figure 2 and Figure 3, runner is served as reasons the entirety that " Z " font flow passage unit is connected in series
In the labyrinth flow-path of " polygonal star " shape, the kinetic energy of water flow can be consumed, slows down the speed of water flow, in a preferred embodiment
In, labyrinth flow-path is integrally in " octagonal star " shape.
In above-described embodiment, as shown in figure 9, round elastic slice 3 uses stainless steel thin slice.
As shown in Figure 1, the present invention is in use, water enters tunnel inlets 13 from water inlet 11, in the effect of annular convex platform 14
Under, it flows through and is capable of forming reserved flow channel space between runner convex body 21 and flow path groove 12.Due to runner convex body 21 and stream
It is slidably connected between road groove 12, depth can change between runner convex body 21 and flow path groove 12.Water flow passes through runner convex body
After runner between 21 and flow path groove 12, out of, runner exit 22 enters flow passage cover plate 2 support cavity 23, pass through round bullet
The water hole 31 of piece 3 reaches the top of round elastic slice 3, then flows into 4 upper cavity of pedestal from the conduction hole 42 in pedestal 4, pedestal 4
Water in upper cavity acts on scraping blade cover board 5, is acted on by hydraulic pressure and pushes up scraping blade cover board 5, and water flow is from adjusting cavity 7
Water outlet 71 flows into outlet cavity 8 and adjusts in the gap that cavity 7 is formed, and is flowed out by water outlet 81.It is continuous with hydraulic pressure
Variation, flow passage cover plate 2 are moved up and down by the effect of hydraulic pressure, send out the flow channel depth between runner convex body 21 and flow path groove 12
Changing.Round elastic slice 3 understands upward, upward to flow passage cover plate 2 movement that deform when hydraulic pressure is excessive and plays limitation
Effect, when hydraulic pressure becomes smaller, round elastic slice 3 has restorable trend, and flow passage cover plate 2 is driven to move downward, flow passage cover plate 2 with
The mutual cooperation of round elastic slice 3 not only can voluntarily be adjusted water flow, can also be played the role of anticlogging.In addition,
Scraping blade cover board 5 is as the effect of hydraulic pressure moves upwards and top elastic support member 6 is made to generate compressive deformation, while bullet
Property support member 6 to restore to the original state can the power downward to scraping blade cover board 5, the two matches, water flow can be adjusted
Control, make to be discharged it is more uniform, and the up and down motion of scraping blade cover board 5 will make adjust cavity 7 water outlet 71 be not easy to plug.
The various embodiments described above are merely to illustrate the present invention, wherein the structure of each component, connection type etc. are all can be
Variation, all equivalents and improvement carried out based on the technical solution of the present invention should not be excluded of the invention
Except protection scope.
