Detailed description of the invention
Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
The invention provides a kind of automatic control water level and contain weir, with reference to Fig. 1, Fig. 1 is the structural representation that automatic control water level of the present invention is contained weir the first embodiment, in one embodiment, this automatic control water level is contained weir and is comprised that two is that be oppositely arranged and be located at respectively the side wall 10 of both sides, river course, and is connected between both walls 10 and culvert top board 20 that stacked on top of one another arranges and contain dam, the end 30; Contain between top board 20 and culvert dam, the end 30 and there is interval, and form the siphon passage 40 that water supply stream passes through; Form respectively upper river 50 and downstream river course 60 at the two ends of siphon passage 40, siphon passage 40 has towards the water inlet 41 of upper river 50 with towards the delivery port 42 of downstream river course 60; Siphon passage 40 has a top, and top is higher than siphon passage 40 optional positions, and top is higher than water inlet 41, and lower than the spilling water position in river course.
Above-mentioned river course is formed by two river levees, and in the present embodiment, above-mentioned both walls 10 can be river levee, also can be attached at respectively the body of wall on two river levees.Above-mentioned culvert top board 20 is located at and is contained the top on dam, the end 30, and the two ends of containing top board 20 are connected with both walls 10 respectively, and the two ends of containing dam, the end 30 are connected with both walls 10 respectively.The height on above-mentioned siphon passage 40 tops can arrange according to actual needs, preferably, needs only the spilling water position a little less than river course.
It is as follows that automatic control water level is contained the operating principle on weir: rise or hold when full when upper river 50 current overflow, as shown in Figure 2, the water level of upper river 50 is higher than the apical position of above-mentioned siphon passage 40, therefore current enter siphon passage 40 from water inlet 41, and hold completely whole siphon passage 40, current flow out from delivery port 42, and this is siphonage.Under siphonage, the current of upper river 50 constantly flow into downstream river course 60 by siphon passage 40, the water level of upper river 50 constantly declines, as shown in Figure 3, in the time that the water level of upper river 50 is between the top of siphon passage 40 and water inlet 41, under siphonage, the current in upper river 50 still drain into downstream river course 60 by siphon passage 40.Until the water level of upper river 50 is while dropping to the position lower than water inlet 41, as shown in Figure 4, air enters in siphon passage 40, and siphonage disappears, and current stop discharge, thereby has realized the upper river 50 water big vast object of automatically overflowing after completely.In the time that the water level in upper river 50 raises gradually and be positioned under the peak of containing dam, the end 30, siphonage does not produce, the interior non-water flow of siphon passage 40 passes through, until the water level in upper river 50 is while being increased on the top of siphon passage 40, siphonage produces again, so repeatedly, can keep all the time water level in upper river 50 between the top and water inlet 41 of siphon passage 40.Because automatic control water level culvert provided by the invention weir does not need artificial participation in big vast process is overflow in realization automatically, and need to, by resources such as outside electric power, therefore effectively not reduce cost.In addition, the effect of flood spillway can be played in above-mentioned automatic control water level culvert weir, also can play the effect discharging water, and has therefore avoided arranging in prior art the design of flood spillway and other special dewatering outlets simultaneously, has further reduced engineering and maintenance cost.
Further, with reference to Fig. 5, Fig. 5 is the structural representation that automatic control water level of the present invention is contained weir the second embodiment, contains the switch valve 22 that top board 20 is provided with at least one pore 21 and opens or close for controlling pore 21.In the present embodiment, the quantity of pore 21, size and position can arrange according to actual needs.For example, can a pore 21 or multiple pore 21 be set at the top end of siphon passage 40 (containing the position near siphon passage 40 tops on top board 20), also the several differing heights of certain in siphon passage 40 place arranges respectively one or more pores 21 respectively, preferably, when pore 21 is at least two, at least two pores 21 height is with respect to the horizontal plane not identical.Above-mentioned switch valve 22 can be a stopper adaptive with pore 21 shapes, size, also can be screw etc., staff can be opened pore 21 or close by instruments such as spanners, also can adopt other modes to arrange, as long as can make switch valve 22 can control the unlatching of pore 21 or close.The top of siphon passage 40 to water inlet 41 places are made as upstream passageway, preferably, pore 21 is located in upstream passageway, be located at the position that is used to form upstream passageway of containing top board 20, by pore 21 is located in upstream passageway, can be by controlling the unlatching of pore 21 or closing the lowest water level that regulates upper river 50.
With reference to Fig. 6, Fig. 6 is the structural representation that automatic control water level of the present invention is contained weir the 3rd embodiment, in the present embodiment, describes as example so that two pores 21 to be set, and one of them pore 21 is located at the top of siphon passage 40, is made as the first pore 211; Another pore 21 is located at bottom or the medium position of upstream passageway substantially, is made as the second pore 212, and the position of the second pore 212 is lower than the highest point of containing dam, the end 30.
It is as follows that automatic control water level is contained weir operating principle: when the water level of upper river 50 is during higher than the first pore 211, as shown in Figure 7, no matter the first pore 211 and the second pore 212 are in opening or closed condition, and siphonic effect all occurs siphon passage 40.The water level of upper river 50 declines gradually, until drop to the first pore 211 places, if now the first pore 211 is opened, air enters in siphon passage 40 by the first pore 211, siphonage disappears, current in upper river 50 stop flowing into downstream river course 60, upper river 50 water levels go up gradually, until exceed the top of siphon passage 40, siphonage produces again, so repeatedly, under the effect of the first pore 211 by the water level limitation in upper river 50 at the first pore more than 211.If now the first pore 211 is closed, siphonage continues, and as shown in Figure 8, the water level of upper river 50 continues to decline under siphonage, until drop to the second pore 212 places; If now the second pore 212 is opened, as shown in Figure 9, air enters in siphon passage 40 by the second pore 212, siphonage disappears, current in upper river 50 stop flowing into downstream river course 60, upper river 50 water levels go up gradually, until exceed the top of siphon passage 40, siphonage produces again, so repeatedly, because the position of the second pore 212 is lower than the highest point of containing dam, the end 30, therefore under the effect of the second pore 212 by the water level limitation in upper river 50 at the second pore more than 212; If now the second pore 212 is closed, siphonage continues, and the water level of upper river 50 continues decline under siphonage, until drop to water inlet 41 places, under the effect of water inlet 41 by the water level limitation of upper river 50 at water inlet more than 41.
Further, pore 21 is connected with peripheral air exhauster.When upper river 50 water levels are during higher than water inlet 41 and lower than the top of siphon passage 40, if now wish to produce siphonage, pore 21 can be connected with air exhauster, by air exhauster, the air in siphon passage 40 be pumped, thereby make the interior generation siphonage of siphon passage 40.Before wet season or arriving in flood season, now the water level of upper river 50 is also not enough to the top higher than siphon passage 40, the generation siphonage that can think by air exhauster, thereby in advance by the water level limitation of upstream passageway at lowest water level, avoided river to rise suddenly and sharply suddenly and flood occurred.
The concrete shape of above-mentioned siphon passage 40 can arrange according to actual needs, and for example, siphon passage 40 can be inverted U-shaped or semicircle setting or the desirable curve of other hydraulics along the cross section of water (flow) direction.The top of siphon passage 40 is made as upstream passageway to water inlet 41 places, and the top of siphon passage 40 to delivery port 42 places are made as downstream passage, and preferably, upstream passageway is greater than the cross section radian of downstream passage along water (flow) direction along the cross section radian of water (flow) direction.More preferably, downstream passage is plane layout.
These are only the preferred embodiments of the present invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes manual of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
