Abstract
The invention relates to an elastic overflow weir. The bottom edge of a weir plate is hinged on a fixed base, a sealing rubber sheet is arranged at the hinged part of the weir plate and the fixed base, the upper surface of the weir plate is of an arc surface, the sensitivity is high, the overflow resistance is low, the overflow rate is fast, and the overflow amount is larger, the closure effect is stable, and the water discharge of large quantity is realized; the back surface of the weir plate is linked with at least a cluster spring fixed on the fixed base, thus, the overflow weir is enabled to have simple outline structure, the parts are reduced, the assembly and the maintenance are convenient, the overflow weir is not limited by the landform, the rise and the fall of the weir plate are stable, and the overflow weir of 1 meter width can be used for replacing a fixed weir of 8 to 15 meter width.
Description
Technical field
The present invention relates in a kind of hydraulic engineering to control in dam discharging and the urban water supply system to water that water dams, the elastic overflow weir of the big discharging of current.
Background technology
In the water system pipe network, should control the water amount of damming in order to reach, solve the purpose of a large amount of dischargings of current again, generally adopt overflow weir to control.Usually adopt the fixed weir control amount of damming at present, fixed weir is a level altitude, mainly plays the effect of damming, and the water that surpasses the amount of damming climbs over the fixed weir weir crest and discharges, its overflow control poor effect.Substitute a kind of adjustable flotative van batardeau of fixed weir, its weir plate is articulated on the firm banking, and the weir plate upper surface connects floating drum by pull rope, rigid bearing, place the counterweight stone roller on the floating drum, increase and reduce by float buoyancy, control weir plate descending and up, realization overflow and the purpose of damming.This pivoted weir strengthens than the fixed weir spillway discharge, but has following shortcoming: the floating drum rigid bearing of control pivoted weir work is subject to the restriction of fabricating yard, and the contour structures complexity is installed inconvenience, working sensitivity and control from view of profit difficulty; The upper surface of weir plate is the plane, and it is big to cross water resistance, the weir plate bumpy motion.
Summary of the invention
In order to overcome the shortcoming that prior art exists, the purpose of this invention is to provide a kind of simple in structure, be convenient to install, cross that water resistance is little, the weir plate motion steadily, overflow and the fireballing elastic overflow weir that dams.
The present invention realizes that the technical scheme that this purpose adopts is: the base of weir plate is articulated on the firm banking, weir plate and firm banking hinged place are provided with the sealing offset plate, the upper surface of described weir plate is an arc surface, the back side of weir plate connects the cluster spring more than at least one, and the other end of cluster spring is fixed on the firm banking.
Further, the described weir plate back side is connected angle with horizontal plane be acute angle, preferred 30-60 °.
After adopting above technical scheme, the beneficial effect that the present invention reaches is:
1, the upper surface of weir plate is an arc surface, highly sensitive, it is little to cross water resistance, flooding velocity is fast, spillway discharge is bigger, and fixedly weir plate and pivoted weir are significantly increased the existing stable effect of damming to spillover efficiency, can realize the discharging of big flow water again, one meter wide overflow weir can support the wide fixed weir of 8-15 rice and use;
2, the weir plate back side connects the cluster spring that is fixed on more than at least one on the firm banking, the elastic force size of cluster spring, number of combinations are decided by the waterpower design, use cluster spring can make the overflow weir contour structures simple, reduce parts, convenient for installation and maintenance, not limited by landform, weir plate rises and falls steadily.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
A kind of elastic overflow weir shown in Fig. 1, the base of its weir plate 1 is articulated on the firm banking 5, and the hinged place adds 4 sealings of fluid sealant plate, and the upper surface of weir plate is an arc surface, the cluster spring 3 that the back side 2 of weir plate connects more than at least one, the other end of cluster spring is fixed on the firm banking 5.Under the condition of not locating resistance, waterpower is greater than weir plate elastic force, and weir plate is descending, opens weir gate; Weir plate elastic force is during greater than waterpower, and weir plate is up, closes weir gate.
Claims (2)
1, a kind of elastic overflow weir, the base of weir plate is articulated on the firm banking, weir plate and firm banking hinged place are provided with the sealing offset plate, it is characterized in that: the upper surface of described weir plate is an arc surface, the back side of weir plate connects the cluster spring more than at least one, and the other end of cluster spring is fixed on the firm banking.
2, elastic overflow weir according to claim 1 is characterized in that: the weir plate back side connects angle with horizontal plane be acute angle, preferred 30-60 °.
