Description
Technical field
The utility model belongs to the gate in hydraulic engineering, specifically the simple novel low water head gate of a kind of structure.
Background technology
In order to barrage retaining on small rivers, again can according to regimen timely adjustment water level, what existing employing was more is rubber dam.But rubber dam also comes with some shortcomings in actual use, according to introduction, the rubber dam life-span is short, within general 15 years, need change a dam bag, really can use and how long also need to determine according to actual conditions; Secondly, operational management difficulty comparatively greatly, needs normal understanding upper pond level situation to decide dam bag and fills the high and dam that collapses, be subject to korneforos floating thing simultaneously and scratch and artificial destruction, often need overhaul, therefore require that the floating thing in river course, place is few; Consider from cost and longevity, dam bag fills high unsuitable frequent with the dam that collapses, and namely rubber dam should not be used for SEA LEVEL VARIATION river course too frequently.
Summary of the invention
The utility model aims to provide a kind of novel low water head gate, and it has structure feature simple, easy to use, effectively can overcome many deficiencies that rubber dam in use exists.
The utility model realizes above-mentioned purpose by the following technical solutions:
A kind of novel low water head gate comprises gate, gate support, triangular mounting arm, hydraulic cylinder, hydraulic cylinder bearing, pull bar, drag link bearing, hinge, free bearing.Described gate is fixed in riverbed concrete foundation by gate support, and gate is connected with gate support by the first hinge on its base; The back side of described gate is connected with the triangular mounting arm with stable support function with free bearing by the second hinge, the middle part of described triangular mounting arm by the 3rd hinge with low water head gate can be made to rise be connected with the hydraulic cylinder landed; Described balance hydraulic cylinder and the stressed pull bar of triangular mounting arm are connected to the end of triangular mounting arm by the 4th dumpling axle, described hydraulic cylinder is connected by the 5th dumpling axle with hydraulic cylinder bearing, pull bar is connected by the 6th dumpling axle with drag link bearing, and described hydraulic cylinder bearing and drag link bearing are fixed on riverbed.
Described gate is the platy structure of arc, is connected with free bearing in gate back side middle and upper part, the bottom of described gate by stud connection in gate support; Hydraulic cylinder bearing and drag link bearing is respectively equipped with in the downstream of gate support; One end of described pull bar to drag link bearing by stud connection, the free bearing at described gate rear portion is had triangular mounting arm by stud connection, passes through stud connection between described triangular mounting arm and pull bar; Described hydraulic cylinder bearing has hydraulic cylinder by stud connection, and the other end of hydraulic cylinder is by the middle part of stud connection to triangular mounting arm.
The quadric chain that described triangular mounting arm, pull bar and gate are formed is by Driven by Hydraulic Cylinder.
Preferably, described free bearing is provided with four altogether, and every two free bearings are one group; Often organize free bearing to there being a hydraulic cylinder, described hydraulic cylinder top is connected with a cross bar, and the two ends of cross bar are connected respectively to corresponding triangular mounting arm.
The utility model overall structure is simple, be easy to manufacture, and cost is low, and Simultaneous Stabilization and reliability have enough guarantees, can be good at the effect realizing water storage and flood discharge; In addition, this structure long service life, has lower loss, does not also need too much maintenance in using; The height of gate can regulate according to actual needs, considerably increases the flexibility of use.
Accompanying drawing explanation
Fig. 1 is rear elevation of the present utility model.
Fig. 2 is the lateral view of gate of the present utility model when rising to peak.
Fig. 3 is the lateral view of gate of the present utility model when reducing as far as possible.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
The novel low water head gate of one as shown in Figure 1, Figure 2 and Figure 3 comprises gate 1, gate support 2, triangular mounting arm 3, hydraulic cylinder 4, hydraulic cylinder bearing 5, pull bar 6, drag link bearing 7, hinge, free bearing 9.
Gate 1 is fixed in riverbed concrete foundation by gate support 2, and gate 1 is connected with gate support 2 by the first hinge 81 on its base, at the back side of gate 1, the bracing frame be made up of two panels quadric chain is set, gate 1 back side is connected with the triangular mounting arm 3 with stable support function with free bearing 9 by the second hinge 82, the middle part of triangular mounting arm 3 by the 3rd hinge 83 with low water head gate 1 can be made to rise be connected with the hydraulic cylinder 4 landed, balance hydraulic cylinder 4 and the stressed pull bar 6 of triangular mounting arm 3 are connected to the end of triangular mounting arm 3 by the 4th hinge 84, hydraulic cylinder 4 is connected by the 5th hinge 85 with hydraulic cylinder bearing 5, pull bar 6 is connected by the 6th hinge 86 with drag link bearing 7, hydraulic cylinder bearing 5 and drag link bearing 7 are fixed on riverbed.
During retaining, hydraulic cylinder 4 promotes piston and extends, and due to the constraint of pull bar 6, hydraulic cylinder 4 is promoted gate 1 by pull bar 6 and triangular mounting arm 3 and upwards hoisted by the rotation of each hinge.During decline, hydraulic cylinder 4 contraction in length, drives pull bar 6 and triangular mounting arm 3 to be rotated down, thus realizes gate 1 and rotated by each hinge and drop to press close in order to sluicing with riverbed, and can stop arbitrarily gate between extreme higher position and extreme lower position as required.
Mechanism can realize fast lifting according to streamflow situation and requirement and decline with the object reaching retaining and sluicing.Easy to operate, simply, safety, reliability is high, practical, and cost is low.
