Abstract
The utility model provides a swirl drainer. The swirl drainer comprises a drainer main body, wherein an inverted conical water draining hole is formed in the drainer main body. A conical bus of the water drainage hole has an angle of 45-80 DEG with the end surface of the water drainage hole; and an internal thread is arranged at the upper part of the water drainage hole. The drainer provided by the utility model has better water drainage efficiency; and the water drainage hole can be prevented from being blocked by impurities so as to very well ensure the smoothness of the drainage hole.
Description
Technical field
The utility model relates to a kind of whirlpool outlet device.
Background technology
Development along with urban construction; Road equipment is also more perfect; Particularly when the laying road road surface; Whenever be spaced a distance a draining well lid or draining double-edged fine-toothed comb just need be set, could guarantee that like this rainwater can be drained through the outlet device on the well lid fast when rainfall, ensure the traffic safety on road surface.Drain hole on the tradition outlet device is generally circle or rectangular through holes, and the side of drain hole is vertical with well lid or double-edged fine-toothed comb end face.The drainage efficiency of this outlet device is lower, and flow rate of water flow is slower, when rainfall is big, causes surface gathered water easily, the influence driving; And owing to usually have some foreign material on the road surface, when foreign material are punched on the drain hole position of outlet device by rainwater, easily drain hole is stopped up, also can cause impeded drainage, even make the draining well lid lose efficacy.
The utility model content
To the above-mentioned deficiency that prior art exists, the main purpose of the utility model is to solve the lower problem of present outlet device drainage efficiency, and a kind of draining fast is provided, and can prevent the whirlpool outlet device that drain hole is blocked.
The technical scheme of the utility model: a kind of whirlpool outlet device, comprise the outlet device body, it is characterized in that, in this outlet device body, be provided with obconic drain hole.
The outlet device of the utility model changes the state of current through drain hole the time through obconic drain hole, makes it produce rotate effect, increases flow velocity with this, and takes foreign material out of, has obviously improved the drainage efficiency of outlet device.
Further technical scheme, the angle of the element of cone of said drain hole and drain hole end face is 45 ~ 80 °.
Further again, be provided with internal thread on the top of drain hole.
With respect to prior art, the utlity model has following beneficial effect:
1, drainage efficiency is high: it is tapered that the outlet device of the utility model is arranged to rounding with drain hole, works as current like this and flow to the drain hole place, because the initial disturbance of flowing; Current can be rotate effect when flowing into drain hole, and along with water flows downward, the sectional area of drain hole reduces gradually; The current radius of gyration reduces gradually; Rotary speed can be increasing when water was discharged downwards like this, and rotate effect strengthens, and drainage efficiency improves.
2, can prevent that foreign material from stopping up drain hole: if foreign material are poured in the drain hole, because under the rotate effect effect that current constantly strengthen, foreign material can be taken out of drain hole, so just can well guarantee the unimpeded of tap.
Description of drawings
Fig. 1 is the vertical view of the utility model whirlpool outlet device;
Fig. 2 is the structure sectional view of the utility model whirlpool outlet device.
Among the figure, 1-outlet device body, 2-drain hole, 3-draining well lid.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described further.
As depicted in figs. 1 and 2; A kind of whirlpool outlet device; Comprise outlet device body 1, this outlet device body 1 is installed on the draining well lid 3, in this outlet device body 1, is provided with obconic drain hole 2; Said drain hole 2 is up big and down small through hole, and the angle of the element of cone of drain hole 2 and drain hole end face is 45 °, 50 °, 55 °, 65 °, 72 °, 78 ° or 80 °.The design angle of this taper hole can come according to the thickness of draining well lid or double-edged fine-toothed comb to select flexibly.The drain hole of utility model has adopted special turbination hole, when current flow to drain hole, because the initial disturbance of flowing; Current can produce rotation, and because drain hole is a bellmouth, along with water flows downward; Sectional area shrinks gradually; The current radius of gyration reduces gradually, and according to the principle of the conservation of angular momentum, radius of gyration reduces then that angular velocity of rotation must increase.Rotary speed can be increasing when water was discharged downwards like this, and rotate effect strengthens, and drainage efficiency improves.When in the water all kinds of impurity being arranged, the effect of sweeping along of current also can strengthen.As long as the volume of foreign material less than drain hole, all can be taken out of drain hole under the rotate effect effect that current constantly strengthen.Drain hole can avoid blocked like this, and drainage effect is also strengthened.
Referring to Fig. 2,, also be provided with internal thread on the top of drain hole 2 in order to strengthen the rotate effect that current flow into the drain hole initial time.
Need to prove at last; Above embodiment is only in order to technical scheme but not the restriction technologies scheme of explanation the utility model; Although the applicant specifies the utility model with reference to preferred embodiment, those of ordinary skill in the art should be appreciated that those modifications that technical scheme of the utility model is carried out perhaps are equal to replacement; And do not break away from the aim and the scope of present technique scheme, all should be encompassed in the middle of the claim scope of the utility model.
