In further embodiment, the big end water inlet of the taper sucker is equipped with water-absorbing sponge.
In preferred scheme, 2 ~ 3 times of the diameter of a diameter of reducer most thin portion point of the arterial drainage.
In preferred scheme, the suction side of the suction hose is equipped with the box that bails, and the tail end for the box that bails is connected to suction hose, scoops The front end of water box is equipped with water inlet.
A kind of foundation surface of concrete dams and lift surface ponding remove device provided by the utility model is led in arterial drainage When some solid stream of water pass through reducer, flow velocity increases, according to Bernoulli equation it is found that in the non-uniform flow tube of thickness, pipe Thin place's flow velocity is big, and the thick place's flow velocity of pipe is small, and the big local pressure of flow velocity is small, and the small local pressure of flow velocity is big, therefore in reducer Pressure becomes smaller, and generates the sucking to surrounding fluid and acts on, is i.e. suction effect, therefore generate suction to water suction air in tube, passes through Suction hose realization is drawn water.The arterial drainage of the device is not required to using blow-off line or drainage pipeline existing for construction site itself In addition power plant to be provided, resource is saved, it is easy to operate.
Description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and examples:
Fig. 1 is the overall structure diagram of the utility model.
Fig. 2 is the scheme of installation of the water absorber of the utility model.
Fig. 3 is the scheme of installation of the box that bails of the utility model,
In figure:Arterial drainage 1, suction hose 2, the first conical pipe 3, the second conical pipe 4, connecting tube 5, valve 6, filter device 7, " L " shape conduit 8, taper sucker 9, water-absorbing sponge 10, bail box 11, water inlet 12.
Specific implementation mode
As shown in Figure 1, a kind of foundation surface of concrete dams and lift surface ponding remove device, including arterial drainage 1 and suction Water pipe 2, generic continuous flow in arterial drainage 1, arterial drainage 1 are equipped with reducer, and the internal diameter of reducer is less than arterial drainage 1 Internal diameter, reducer side wall connection suction hose 2 so that reducer is connected to suction hose 2, the suction side of suction hose 2 is placed on ponding position It sets.Reducer can be integrally formed with arterial drainage 1, and reducer diameter shrinks the internal diameter for making internal diameter be less than arterial drainage 1.
Arterial drainage 1 selects blow-off line or drainage pipeline of construction site etc., to ensure to be changed without all site operations Pipeline, reducer include the first conical pipe 3, the second conical pipe 4 and connecting tube 5, and the both ends of connecting tube 5 are separately connected the first taper Pipe 3 and the smaller one end of 4 internal diameter of the second conical pipe, the first conical pipe 3 and 4 internal diameter of the second conical pipe it is larger one end and draining it is dry Pipe 1 connects, and suction hose 2 is connected to connecting tube 5.First conical pipe 3 and the second conical pipe 4 can carry out screw thread with arterial drainage 1 Connection, facilitates the repacking of site operation pipeline, meanwhile, multiple reducers, reducer connection pair can be set on arterial drainage 1 The suction hose 2 answered is arranged multiple suction hoses 2 and can be carried out at the same time and draws water.A diameter of connecting tube 5 of the arterial drainage 1 it is straight 2 ~ 3 times of diameter.1.5 ~ 2 times of 2 diameter of a diameter of suction hose of connecting tube 5.Guarantee has enough water pressures to generate suction hose 2 Suction ensures that ponding is smoothly discharged.
The suction hose 2 is obliquely installed, and suction hose 2 is tilted to the water inlet direction of arterial drainage 1.
The suction hose 2 and the angle of arterial drainage 1 are 60 ~ 70 °.
The suction hose 2 is equipped with valve 6.Valve 6 can select shut-off valve or check-valves, prevent arterial drainage 1 from stopping When draining, the residual water in arterial drainage 1 is flow backwards from suction hose 2.
The suction side of the suction hose 2 is equipped with filter device 7.Filter device can select filter screen or filter cotton, prevent Impurity in ponding blocks suction hose 2, influences ponding discharge.
As shown in Fig. 2, the suction side of the suction hose 2 is equipped with water absorber, water absorber includes " L " shape conduit 8 and cone One end of shape sucker 9, " L " shape conduit 8 is connected to the suction side of suction hose 2, and the other end is connect with the small end of taper sucker 9, cone The big end water inlet of shape sucker 9 is placed on ponding position.When water accumulating volume is bigger, deep, the suction side of suction hose 2 can be with It submerges in ponding completely, but when water accumulating volume is less, the suction side of suction hose 2 cannot complete ponding pumping because being higher than ponding height It is discharged, taper sucker 9 and the ponding face paste of setting are closed, can be fully erased by ponding.
The big end water inlet of the taper sucker 9 is equipped with water-absorbing sponge 10.10 one side of water-absorbing sponge can play filtering On the other hand effect can will remain less ponding absorption.
Embodiment 2:It is different from embodiment 1, as shown in figure 3, the suction side of the suction hose 2 is equipped with the box 11 that bails, scoop Water box 11 are threadedly coupled with suction hose 2, and the tail end for the box 11 that bails is connected to suction hose 2, and the front end for the box 11 that bails is equipped with water inlet 12.When water accumulating volume is less, can not achieve pump drainage removing, the box 11 that will bail is connected on suction hose 2, and ponding is swept into the box that bails It 11 and is discharged by suction hose 2.
The above embodiments are only the optimal technical scheme of the utility model, and are not construed as the limit for the utility model System, the technical solution that the scope of protection of the utility model should be recorded with claim include the technical solution of claim record The equivalents of middle technical characteristic are protection domain.Equivalent replacement i.e. within this range is improved, also in the utility model Protection domain within.
