For making the object of the embodiment of the present invention, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Fig. 1 is the structural representation of power unit one embodiment of hinge movable dam of the present invention.As shown in Figure 1, the power unit of the hinge movable dam of the present embodiment, comprises bar linkage structure and hydraulic cylinder 1; Bar linkage structure comprises connecting rod 2 and lower link 3, and one end of upper connecting rod 2 and one end of lower link 3 are coupling; The other end of upper connecting rod 2 is connected with the lock body back of hinge movable dam, and one end and the connecting rod base 4 of lower link 3 are hinged, and connecting rod base 4 is fixed on gate foot; One end and the hydraulic cylinder base 5 of hydraulic cylinder 1 are hinged, and hydraulic cylinder base 5 is fixed on gate foot, and the other end of hydraulic cylinder 1 is connected with lower link 3, by driving lower link 3 to drive upper connecting rod 2 to move, rising to drive the lock body of hinge movable dam or declining.
In the present embodiment, hydraulic cylinder 1 drives upper connecting rod 2 to complete rising dam and falling dam of hinge movable dam by driving lower link 3 to swing, namely hydraulic cylinder 1 is by acting on lower link 3, realize the impulse stroke of hydraulic cylinder 1 and the amplification of driving force, to drive upper connecting rod 2 to move, thus the lock body of hinge movable dam is driven to realize elevating movement.One state diagram of the power unit that Fig. 2 is the hinge movable dam shown in Fig. 1.Another state diagram of the power unit that Fig. 3 is the hinge movable dam shown in Fig. 1.Such as shown in Figure 2, when hydraulic cylinder 1 drives the lock body of hinge movable dam to rise, hydraulic cylinder 1 stretches out, upwardly lower link 3, the thrust of hydraulic cylinder 1 can be decomposed into thrust upwards and point to one end active force upwards of this lower link 3 along lower link 3 on lower link 3, like this, lower link 3 not only can be made upwards to rise, simultaneously thrust upwards can promote connecting rod 2 and upwards rises, thus the lock body promoting hinge movable dam rises.
Again such as shown in Figure 3, when hydraulic cylinder 1 drives the lock body of hinge movable dam to decline, hydraulic cylinder shrinks, hydraulic cylinder 1 pulls lower link 3 downwards, the pulling force of hydraulic cylinder 1 can be decomposed into downward pulling force and point to the downward active force of the other end of this lower link 3 along lower link 3 on lower link 3, like this, lower link 3 not only can be made downwards to retract, downward thrust can pull connecting rod 2 upwards to fall after rise simultaneously, thus pulls the lock body of hinge movable dam to decline.
The power unit of the hinge movable dam of the present embodiment, driving stroke and the driving force of hydraulic cylinder 1 is amplified by the bar linkage structure adopting upper connecting rod 2 and lower link 3 to form, when the impulse stroke of hydraulic cylinder 1 and driving force constant, the lifting of the lock body that hydraulic cylinder 1 can be made dam facing height can be driven higher by bar linkage structure, the power unit of the hinge movable dam of the present embodiment is adopted to drive hinge movable dam, hinge movable dam structure can be improved, strengthen the ability that hinge movable dam adapts to higher water retaining height, improve the integrally-built stability of hinge movable dam, strengthen the safety of hinge movable dam, extend the application life of hinge movable dam.
The power unit of the hinge movable dam of above-described embodiment, in actual use, the lock body of hinge movable dam will be made under normal circumstances to keep raised configuration, i.e. state in dam, therefore when under the dynamic action at hydraulic cylinder, after being risen by the lock body of hinge movable dam, hydraulic cylinder 1 still will provide the power of needs to lower link 3, hydraulic cylinder 1 continuous firing will be caused like this, reduce the application life of hydraulic cylinder 1.Therefore in order to overcome the above problems, present invention also offers following examples.
Fig. 4 is the structural representation of another embodiment of power unit of hinge movable dam of the present invention, and as shown in Figure 4, the power unit of the hinge movable dam of the present embodiment, on basis embodiment illustrated in fig. 1, further comprises braced structures; This braced structures comprises base for supporting 6, support bar 7 and release mechanism 8.One end of support bar 7 is connected to the middle part of lower link 3, and the other end is connected with release mechanism 8; When lower link 3 moves, release mechanism 8 is driven to slide along base for supporting 6 by support bar 7.
Fig. 5 is the structural representation of the base for supporting of braced structures in Fig. 4, and Fig. 6 is the top view of the base for supporting shown in Fig. 5.As shown in Figure 5, in the braced structures of the power unit of the hinge movable dam of the present embodiment, base for supporting 6 can be fixedly connected with gate foot, and base for supporting 6 is provided with two wedge shape limiting plates 61 and at least one pair of wedge shaped support plate 62; Two wedge shape limiting plates 61 are set in parallel in base for supporting 6 center line both sides, particularly, as shown in Figure 4, and the base for supporting 6 shown in composition graphs 5, can show that the beveled end A of each wedge shape limiting plate is away from lower link base 4.As shown in Figure 5 and Figure 6, two wedge shape limiting plates 61, for constrained solution latch mechanism 8 (not shown), make release mechanism 8 hold B to slide by the beveled end A of wedge shape limiting plate 61 to facing directly of wedge shape limiting plate 61 between two wedge shape limiting plates 61; And when the length of the distance superelevation wedge shape limiting plate 61 that release mechanism 8 slides, depart from the constraint of wedge shape limiting plate 61, for release mechanism 8 provides sliding rail, release mechanism 8 is made to hold B to slide to the beveled end A of wedge shape limiting plate 61, to realize release mechanism reverse slide along facing directly of wedge shape limiting plate 61;
As shown in Figure 5 and Figure 6, at least one pair of wedge shaped support plate 62 is set in parallel between two wedge shape limiting plates 61, and the beveled end C of each wedge shaped support plate 62 is arranged on one end of the beveled end A away from wedge shape limiting plate 61 of wedge shaped support plate 62, namely the beveled end C of at least one pair of wedge shaped support plate 62 and beveled end A of wedge shape limiting plate 61 is oppositely arranged.At least one pair of wedge shaped support plate 62 is for when release mechanism 8 is subject to the constraint of two wedge shape limiting plates 61, for release mechanism 8 provides sliding rail, make release mechanism 8 along at least one pair of wedge shaped support plate 62 beveled end C at least one pair of wedge shaped support plate 62 face directly end D slide, and when release mechanism 8 depart from least one pair of wedge shaped support plate 62 face directly end D time, stop that release mechanism 8 slides to the beveled end C of at least one pair of wedge shaped support plate 62, to stop release mechanism 8 reverse slide, and power is provided support to release mechanism 8.Such as shown in Figure 5, in the braced structures of the power unit of the hinge movable dam of the present embodiment, be specifically described for a pair wedge shaped support plate 62.
Further alternatively, in the power unit of the hinge movable dam of the present embodiment, the base for supporting 6 of braced structures is also provided with two guide strips 63, one end of two guide strips 63 holds B to connect with facing directly of corresponding wedge shape limiting plate 61 respectively, the facing directly of two guide strips 63 and wedge shape limiting plate 61 hold the width between the unconnected other end of B be greater than two guide strips 63 and wedge shape limiting plate 61 face directly hold B to be connected one end between width.Two guide strips 63, for adjusting the width of release mechanism 8, make release mechanism 8 enter two wedge shape limiting plates 61, and then restrained.Because release mechanism 8 needs to slide between two wedge shape limiting plates 61 or slide along two wedge shape limiting plates 61, therefore the width of release mechanism 8 is needed to regulate, when release mechanism 8 is along before sliding between two wedge shape limiting plates 61, two guide strips 63 can be introduced into, and by two guide strips 63, release mechanism 8 is gradually reduced, finally make the width of release mechanism 8 meet the width slided between two wedge shape limiting plates 61.When release mechanism 8 slides along two wedge shape limiting plates 61, release mechanism 8 is owing to having departed from the constraint between two wedge shape limiting plates 61, so release mechanism 8 can recover to enter the width before two guide strips 63, now the width of release mechanism 8 is greater than the width between two wedge shape limiting plates 61, thus B can be held to slide to the beveled end A of wedge shape limiting plate 61 along facing directly of wedge shape limiting plate 61.
Particularly, sectional view when Fig. 7 is the release mechanism elongation of braced structures in Fig. 4, sectional view when Fig. 8 is the release mechanism shortening of braced structures in Fig. 4.Such as shown in Figure 7, release mechanism 8 can comprise main back shaft 81, two expansion back shaft 82 and two springs 83.Each expansion back shaft 82 is connected with the end of main back shaft 81 by corresponding spring 83, and under the elastic force effect of spring 83 can in main back shaft 81 free-extension, specifically as shown in Figure 8.Each expansion back shaft 82, when being in elongation state, the total length that main back shaft 81 and two expand back shaft 82 is less than the maximum open width in Fig. 5 or Fig. 6 between two guide strip 63 other ends, be greater than the width between two wedge shape limiting plates 61 in Fig. 5 or Fig. 6, expand back shaft 82 to make two to enter between two wedge shape limiting plates 61 along two guide strips 63 in Fig. 5 or Fig. 6, and along two wedge shape limiting plate 61 reverse slide.As shown in Figure 7, the length of main back shaft 81 is greater than the width in Fig. 5 or Fig. 6 between at least one pair of wedge shaped support plate 62, and when each expansion back shaft 82 is compressed in main back shaft 81, main back shaft 81 can slide along at least one pair of wedge shaped support plate 62.
Fig. 9 is for rise dam status of processes figure, Figure 10 is for rise dam process release mechanism and base relative position top view, Figure 11 is the sectional view of the lower support structure of state in dam, and Figure 12 is for falling dam status of processes figure, and Figure 13 is for falling dam process release mechanism and base relative position top view.The braced structures specific works process of the power unit of the hinge movable dam of the present embodiment is as follows:
As shown in Figure 9 and Figure 10, when in hinge movable dam rise process, lower link 3 moves upward, and drive release mechanism 8 to slide by support bar 7, slip into the other end of two guide strips 63 at release mechanism 8 before, two spring 83 (not shown) are not compressed, two expansion back shaft 82 (not shown) stretch out in main back shaft 81, the total length of main back shaft 81 and two expansion back shafts 82 is less than the maximum open width between the other end of two guide strips 63, after release mechanism 8 slips into the other end of two guide strips 63, compressed by these two guide strips 63 gradually, spring 83 storage power simultaneously.After release mechanism 8 enters two wedge shape limiting plates 61, by the constraint of two wedge shape limiting plates 61, two expansion back shafts 82 can continue to be contracted in main back shaft 81.Now main back shaft 81 holds D (not shown) to slide along the beveled end C (not shown) of wedge shaped support plate 62 to facing directly of wedge shaped support plate 62, and when hinge movable dam is elevated to certain altitude, release mechanism 8 departs from facing directly of wedge shaped support plate 62 and holds D.As shown in figure 11, main back shaft 81 drops from the end D that faces directly of wedge shaped support plate 62, height due to the center of gravity of main back shaft 81 is less than the height facing end D directly of wedge shaped support plate 62, when after the active force of cancelling hydraulic cylinder 1, wedge shaped support plate 62 provides support power to main back shaft 81, main back shaft 81 cannot be slided to the direction of the beveled end C of wedge shaped support plate 62, now can realize staying dam by means of only braced structures.
As shown in Figure 12 and Figure 13, when in hinge movable dam decline process, because wedge shaped support plate 62 is to the support force effect of main back shaft 81, main back shaft 81 cannot slide to the direction of the beveled end C (not shown) of wedge shaped support plate, hinge movable dam can not be declined, therefore hinge movable dam is needed to raise certain angle again, be preferably 5 °-10 °, release mechanism 8 is slided a segment distance, exceed the length of wedge shape limiting plate 61, depart from the constraint of wedge shape limiting plate 61, spring 83 (not shown) releases energy, make two to expand back shaft 82 to stretch out in main back shaft 81, now carry out again falling dam, because two expansion back shafts 82 stretch out in main back shaft 81, the total length making main back shaft 81 and two expand back shaft 82 is greater than the width between two wedge shape limiting plates 61, release mechanism 8 cannot return between two wedge shape limiting plates 61, but hold B (not shown) to slide along the beveled end A (not shown) of two wedge shape limiting plates 61 to facing directly of wedge shape limiting plate 61 by two expansion back shafts 82, release mechanism 8 is no longer by the support force of wedge shaped support plate 62, hinge movable dam can fall dam, and enter and rise dam and fall dam process next time.
It should be noted that, when arranging multipair wedge shaped support plate 62, when can realize the height difference of hinge movable dam rise, complete the support of braced structures to lower link 3, thus making hinge movable dam keep current lifting heights, its course of work is consistent with the above-mentioned course of work, does not repeat them here.The position that support bar 7 is connected with lower link 3 can connect according to actual conditions, and preferably support bar 7 is connected at same position up and down connecting rod 3 with hydraulic cylinder 1.
