Abstract
A kind of flexible thin film elevating and falling weir that is fixed on the concrete structure top in the water.Delivery pipe has an opening to be positioned the inner lowest part of covering, so that elevating and falling weir descends fully, water is flow through smoothly.
Description
The present invention relates to the elevating and falling weir of generally forming, especially have the weir of the inflatable that has improved tapping equipment by fexible film.
The elevating and falling weir that fexible film is made is fixed on the top of the concrete structure in the waters of controlled water flow, by making it to rise, perhaps makes it to descend by venting to the elevating and falling weir inflation, thus controlled water flow.
The basic structure of inflatable flexible thin film elevating and falling weir comprises the covering of rubber fabric or similar articles, and this covering is fixed to the top of concrete structure.Pressure medium as air and/or water one class is charged into covering, makes elevating and falling weir be raised to a permanent position, and pressure medium is emitted from covering, and elevating and falling weir is contracted to folded position (for example, Japanese uncensored patent publication No. 11702/1965 and 2371/1969).
With reference to accompanying drawing 1(prior art), when the high weir top that inflatable flexible thin film elevating and falling weir and concrete are made joins, the performance that can obtain to increase the water dike.But discharge water (4) is accumulated to the bottom of covering (2).This is because the covering bottom is positioned at below the water level that fills/put mouthful (3).Filling/put mouthful (3) is used for filling/release body to covering.By filling/put pipe (5), the airborne water vapour that sprays into covering (2) is by the water cooling in the elevating and falling weir.Vapor condensation enters water (4).Thereby when covering was exitted, water still remained in the covering.The flexible elevating and falling weir of residual water overslaugh is retracted to the folded position that is positioned at the concrete structure top fully.After the covering venting, the overslaugh water level drops to the top of concrete structure smoothly.
In common flexible thin film elevating and falling weir, because fill/put mouthful (3) of water are positioned at more than the lowest water level of covering (2), residual water is present in covering folded position bottom, can not be discharged fully.
At the shortcoming of above-mentioned prior art, task of the present invention provides an improved flexible thin film elevating and falling weir.Invention provides a flexible thin film elevating and falling weir, and it has a discharging mouth of pipe, and this mouth of pipe is positioned at the bottommost of the covering of rubber fabric, and is fixed on the concrete structure top.
Read example explanation down in conjunction with the accompanying drawings, advantage of the present invention and progress are conspicuous.Identical label is represented same parts or like in the accompanying drawing.
Fig. 1 (prior art) is the cross section of common elevating and falling weir, and this elevating and falling weir is fixed on the concrete structure.Fig. 1 (a) represents this elevating and falling weir setting (inflation) position, and Fig. 1 (b) represents the folded position of this elevating and falling weir.
Fig. 2 and Fig. 3 represent elevating and falling weir of the present invention.Fig. 2 is the cross section of an embodiment, wherein delivery pipe with fill/put the pipe be connected.Fig. 3 (a) is delivery pipe and fills/put pipe and divide the embodiment that is arranged.Fig. 3 (b) is the cross section in river, invents said elevating and falling weir and places on the river.
Fig. 4 (a) reaches the delivery pipe emission effect separately of two embodiment of the present invention that (b) explain.
The characteristic of delivery pipe of the present invention (6) is described in conjunction with Fig. 2 and Fig. 3, and the opening (7) of delivery pipe (6) is positioned at the lowest part of covering.On Fig. 2 and opening (7) position shown in Figure 3, delivery pipe (6) is connected with covering (2).
As shown in Figure 2, delivery pipe (6) with fill/put pipe (5) and be connected.Forming the quantity and the size of delivery pipe (6) decides according to the width in river.
Fill/put link position between pipe (5) and the delivery pipe (6) and be lower than opening (7) position on the delivery pipe (6), so that make water from covering (2) discharging smoothly.
Fig. 3 represents the another kind of arrangement of pipe, and delivery pipe (6) is with to fill/put pipe (5) separate.When in case of necessity, the water in the covering (2) is discharged by delivery pipe (6).Embodiment shown in Figure 3 comprises operation room (10), and this operation room is connected with pipe (6) with pipe (5).
As mentioned above, except that the opening that fills/put pipe (5) (3), also be provided with opening (7), it is positioned at the lowest part of covering (2).Therefore, discharge water (4) can not remain in the covering (2), and it is by opening (7) discharging smoothly of pipe (6).
In one embodiment, fill/put pipe and also can be used as delivery pipe (6), when the opening that fills/put pipe was positioned at the lowest part of covering (2), emission effect may reduce.The diameter that fills/put pipe depends on filling/putting the time of elevating and falling weir.In general, the caliber scope is 50～150 millimeters.
When filling/putting pipe and have major diameter D, need big flange be set for opening.Shown in Fig. 4 (a), it makes the distance A increase of the lowest part of covering to opening.Otherwise, when fill/put pipe just like shown in Fig. 4 (b) than minor diameter D ' time, littler than the distance A shown in Fig. 4 (a) from the lowest part of covering to opening apart from B.So, the emission effect of the embodiment shown in Fig. 4 (b) good than shown in Fig. 4 (a).
So the present invention can comprise a diameter less than the delivery pipe that fills/put the pipe diameter, and be provided with opening at the covering lowest part.
According to the present invention, delivery pipe is gathered extreme lower position, so that water is discharged smoothly.Thereby can make elevating and falling weir rise fully or descend, water level drops to covering folding place.
According to aforementioned and accompanying drawing, other embodiments of the invention and improvement will be conspicuous for ordinary skill.Just because of this, the present invention is not subjected to unsuitable restriction, and all various replacements that comprise within the scope of the following claims all belong to design of the present invention.
Claims (3)
1, flexible thin film elevating and falling weir it comprise:
Be used for waterbornely, can be fixed on the flexible covering at concrete structure top.
At one end have the fluid of an opening to fill/to put pipe, it makes fluid communicate with flexible covering inside.So that flexible covering charges into or exhaust fluid.
Have a delivery pipe at least, its first end has an opening, and this opening is positioned at the extreme lower position of flexible covering inside.
2, according to claim 1, second end of delivery pipe is connected to the end that the low fluid of brake specific exhaust emission tube opening fills/put pipe.
3, according to claim 1, it is separate that delivery pipe and fluid fill/put pipe, so that does not have fluid flow between the two.
