The specific embodiment
Towed flap arrangement of the present utility model can be installed on the sidewall or diapire of pond body or tank body, tank etc., is the retaining side in the body of pond, and the pond is external to be the emptying side; Separated by pool wall 30 between retaining side and emptying side, pool wall 30 can be concrete structure or steel plate.
Embodiment 1
Fig. 2 is opened in the structural representation of the towed flap arrangement of pool wall 30 for through hole 2.Holder device comprises the holder device 41 that is connected flashboard 10 both sides, is fixed on the guide rod 42 at flashboard middle part.Winding plant comprises elevator fixed part 53, elevator guide wheel 51 and the lift rope 52 on this guide wheel, and an end of lift rope 52 is connected with guide rod 42.Counter weight device is positioned at the external emptying side in pond.Counter weight device comprises the counterweight fixed part 61 that is fixed on the pool wall, counterweight guide wheel 62, and counterweight rope 63 and counterweight 65 on the guide wheel are provided with suspension hook 64 at an end of described counterweight rope, are used to hang counterweight 65; The other end of counterweight rope 63 is connected with the guide rod 42 of holder device 41.
Flashboard 10 stresses when this device is closed, see Fig. 2:
When flashboard 10 cut out, flashboard 10 was subjected to the pulling force from counterweight 65, and counterweight rope 63 is tightened up at this moment, and lift rope 52 is in relaxed state.This moment, flashboard 10 was by from the pulling force of counterweight 65 drawing on the retaining side that has leaned against pool wall 30 tightly.Because counterweight 65 determined, also stablize constantly so act on the pulling force size of counterweight rope 63 on the flashboard 10, promptly the size of sealing load is stable.
Flashboard 10 stresses when this device is in opening, see Fig. 2:
When this installs in off position in the process that is opened, lift rope 52 by relaxed state to being tightened up at leisure, when from the power of winding plant more than or equal to join liquid effects in 65 gravity and the pond flashboard 10 upward pressures and the time, flashboard 10 is pulled away from the inwall of through hole 20 by lift rope 52, when thereby flashboard 10 was in opening, the counterweight rope 63 of flashboard 10 both sides was all stressed with lift rope 52.
Because in practical operation, there are reasons such as machining accuracy is not enough, alignment error, sedimentation and deformation, wearing and tearing, may exist between 30 two sealing surfaces of flashboard 10 and pool wall and be uneven and spacing does not wait, in order to realize automatic adjustment, be the rubber annular gasket 71 of cavity and interior pressurising power fluid media (medium) in the middle of the preferred employing of this device.See Fig. 5, annular gasket 71 can adapt to situation such as machining accuracy is not enough, alignment error, sedimentation and deformation, wearing and tearing automatically and between the sealing surface that causes be uneven and spacing does not wait.The flowability of the fluid media (medium) in annular gasket 71 cavitys makes annular gasket 71 each site pressure all equate, the sealing surface around the through hole is good seal all.
Fig. 3 is opened in the structural representation of the towed flap arrangement at the bottom of the pond for through hole 2.Described holder device 41 1 ends are fixed on pool wall, and the other end is connected with winding plant; Flashboard 10 moves in the scope that holder device is set.Guide rod 42 can pass holder device by guide pin bushing 421, and an end of guide rod 42 and flashboard 10 are fixing, and the other end is connected with winding plant, and guide rod 42 pulling flashboards 10 move on support.When through hole 20 is opened on the diapire in pond, can be directly installed on flashboard 10 belows to counterweight 65, also can be installed in the flashboard top.
As shown in Figure 4, in order to realize better sealing effectiveness, preferred flashboard 10 be a circle, and flashboard 10 also can be square or other shapes, and for example flashboard 10 is rectangle or square, when flashboard 10 when being non-circular, then needs to add an anti-switch block 45.
The utility model can be applicable to the workplace of through hole 2 positions on pond diapire, pond sidewall even pond roof.Can carry out the conversion of counterweight forces or elevator force direction by support, guide wheel, counterweight rope and lift rope.
Preferred lift rope is in relaxed state when closing, and will make flashboard 10 farthest bear the active force of counterweight 65 like this.
Preferably, at the one-sided or bilateral of flashboard 10 or pool wall 30 rubber weather strip 71 is installed.The hollow ring weather strip 71 of interior pressurising power fluid media (medium) shown in Figure 5.71 pressured 72 of weather strips are fixed on the flashboard 10 it.State when Fig. 5 is flashboard 10 unlatchings; Fig. 6 is the state of flashboard 10 when closed by the counterweight effect.
As Fig. 7, the moving contact site of weather strip 71 can process specific shape, to increase the partially sealed pressure of sealing surface.The contact site can be one or more projections 711, to reduce contact area, increases sealing load; The contact site also can be processed into the shape of comma tail, can make sealing surface be close to sealed like this, thereby realizes respond well, reliable and stable sealing.Also can be other shapes that are suitable for sealing.
As Fig. 8, be another embodiment of the present utility model.When flashboard 10 is bigger, heavier, can be without holder device, but can make dolly 100 to flashboard, guide wheel 102 is installed, supporting guide 101 is set below the flashboard car 100, to bear the gravity of flashboard, guide rail 101 is by taking turns 102 weight of bearing flashboard car 100, and wheel 102 can roll on guide rail 101.
Fig. 9 is another embodiment of the present utility model.When the area of flashboard 10 is bigger, can be without holder device, but hanging nose 54 is set respectively in the both sides of flashboard 10, the hanging nose 54 of both sides can make flashboard 10 be in the state perpendicular to stay cord under the tension of lift rope 52 and counterweight rope respectively.In order to make pulling force more even, can utilize 3 principles of determining a face, 3 hanging noses 54 respectively are set in the flashboard both sides, connect with 3 ropes respectively, converge into one, to obtain pulling force more uniformly.
Embodiment 5
As Figure 10, be another embodiment of the present utility model.At this moment, through hole 2 is opened on the inclined wall, can lead by support 41 and guide wheel, makes the pulling force that is directed downwards of counterweight 65 change into the vertical tension that acts on flashboard 10.
In order when through hole and paddle sizes are all big, sufficient intensity to be arranged also, floor 44 can be set, as shown in Figure 3 on flashboard.
