The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further described.
As shown in Figure 1, water tower for river course earial drainage of the present invention, comprise tower body 2, on described tower body 2, be provided with water inlet, the quantity of water inlet can be 1, and 2 or other quantity are to be provided with 2 water inlets in Fig. 1, be respectively the first water inlet 22 and the second water inlet 24, on tower body 2, be also provided with outfall 27 and for making current in river course change after flow direction again the tower body that flows into tower body inside by the described water inlet wall 23 that blocks water.
During use, as depicted in figs. 1 and 2, can be in river course 3 interior above-mentioned water tower be set, the outfall of tower body 27 is communicated with the entrance of drainage gallery 1, current in river course are only introduced into behind tower body inside, could enter drainage gallery 1 by the outfall 27 of tower body, can not directly enter drainage gallery 1; And, make the water inlet of tower body 2 between tower body waterwall 23 and the outfall 27 of tower body 2, for example the first water inlet 22 in Fig. 1 and the second water inlet 24 are between tower body waterwall 23 and the outfall 27 of tower body 2, can first make by tower body waterwall 23 like this that river course 3 is interior to be changed after flowing to and by the water inlet of tower body 2, enter tower body inside again towards the mobile current of drainage gallery 1, then the outfall 27 by tower body 2 flows into drainage galleries 1.Known by above-mentioned analysis, current are after striking tower body waterwall 23 change directions, a part of sandstone in current can be deposited to bottom, river course, the sandstone content that makes to enter in the current of tower body inside reduces, and then the sandstone content that can make to enter in the current in drainage gallery 1 reduces, be conducive to reduce the wearing and tearing of the bed loads such as sandstone to drainage gallery 1, also can be conducive to avoid too much causing because of sandstone content the obstruction of drainage gallery 1.
On the basis of the above, in order to make to enter sandstone content in the current in drainage gallery 1 still less, described tower body inside is provided with and makes the current that flow into tower body inside change the inside stop water flowing out from outfall 27 again after flow direction.As shown in Figure 1 to Figure 3, because tower body inside is provided with inner stop water, by the water inlet 22 of tower body 2 and the current of water inlet 24 inflow tower body inside, first by inner stop water, changed after flow direction, then flow into drainage galleries 1 by the outfall 27 of tower body 2.By inner stop water, can make current enter by inner stop water, to be hindered behind tower body inside and change the flow direction, current change after the flow direction, part sandstone in current are precipitable around inner stop water, sandstone content in current is further reduced, and then the sandstone content that can make to enter in the current in drainage gallery 1 further reduce.The embodiment of above-mentioned inner stop water has multiple, and the maze-type structure that for example can be formed by multiaspect body of wall makes current in labyrinth passage, repeatedly change flow direction, fully makes the sandstone precipitation in current.If the form more complicated of inner stop water, may make the speed of current slower, earial drainage efficiency is lower.In order to make designs simplification, constructability, the current that make to enter in drainage gallery 1 keep flow velocity faster, thereby guarantee higher earial drainage efficiency, as shown in figures 1 and 3, described inner stop water comprises the inside wall that blocks water, the second inside wall 25 and the first inside wall 26 that blocks water that blocks water for example, described inside blocks water the metope of wall towards adjacent water inlet, for example the block water metope 29 of wall 25 of the second inside blocks water the metope 28 of wall 26 towards the first adjacent water inlet 22 towards the second adjacent water inlet 24, the first inside.Adopt said structure, during use, current are entered behind tower body inside by water inlet, first striking corresponding inside blocks water on wall, as shown in the arrow in Fig. 1, the current after shock can change flow direction, and the part sandstone in current can be deposited to the block water bottom of wall, corresponding inside.
In order further to reduce the sandstone content that enters the current in drainage gallery 1, described water inlet towards with outfall towards vertical.As shown in Figure 1, the first water inlet 22 and the second water inlet 24 towards all with outfall 27 towards vertical.The current that this design makes the to enter tower body inside flow direction that only changes could be discharged by outfall, and because the change amplitude of flow direction is larger, is extremely conducive to make the sandstone in current to be deposited to tower body bottom.If said structure and inner stop water are used jointly, can make the current that enter tower body inside force change flow direction repeatedly, the sandstone content that enters the current in drainage gallery 1 for minimizing is very favourable.
In addition, in order to make to enter the sandstone content of the current of tower body inside, further reduce, as shown in Figure 1, described tower body blocks water on the sidewall of tower body corresponding to the two ends of wall 23 and is respectively arranged with a described water inlet, namely the first water inlet 22 and the second water inlet 24, block water on the opposed sidewall of wall 23 and be provided with described outfall 27 with tower body on described tower body 2, as shown in Figure 1, in one end of tower body, be provided with the tower body wall 23 that blocks water, on the sidewall of the other end of tower body, be provided with above-mentioned outfall 27.This setup, can make on the one hand by tower body waterwall, to change direction current in the river course in and be divided into two-way, enters tower body inside respectively by two water inlets, can make like this to enter the flow velocity reduction of the current of tower body inside, is conducive to the precipitation of sandstone; On the other hand, above-mentioned set-up mode makes outfall between two water inlets, and then makes two strands of current that entered by two water inlets can mutually clash into and converge at outfall place, is so also conducive to make the middle part sandstone of current to precipitate.
On the basis of the above, as depicted in figs. 1 and 2, described the first water inlet 22 is extended to the top of tower body 2 by the bottom of tower body 2, and the top 21 of the first water inlet 22 is opening end.Because the top of water inlet is opening end, be conducive to by instrument, stretch into the bottom of water inlet by the top of water inlet so on the one hand, the sandstone of water inlet bottom annex alluvial are cleared up, guarantee the unimpeded of water inlet; On the other hand, water level in river course can raise tower body after rising accordingly, namely at the top of original tower body, continues to build new tower body, because the top of water inlet is opening end, be therefore convenient to make the height of water inlet also with the rising of tower body height, to build rising.
