Description
Technical field
The utility model relates to storm sewer field, the storm sewer partition of especially a kind of anti-backflow.
Background technique
The storm sewer in city is used to drain from urban district to river.And rainy season amount of rainfall it is larger when, local river water level can
It can sharp rise, so that river water be caused to flow backward.River water can cause difficulty to the municipal and environment-friendly work in urban district after flowing backward, can be to low
The even resident's personal safety of the house property in hollow region threatens.
There are some anti-backflow structures for sewer pipe on the market, is such as sealed using the floating ball of up and down motion when flowing backward
Seal, and it is usually then detached from seal under the effect of gravity.But this kind of floating ball, kickboard in normal work its own
Space between periphery and drainage pipeline is practical drainage channel, and drainage channel is very narrow, and attainable flow velocity is smaller.Meanwhile these
The structure of design is more fine, be easy to cause poorly sealed situation under sundries interference.
And people want running check storm sewer, and the design of these structures is not easy to people and checks maintenance.

Specific embodiment
It is with reference to the accompanying drawing, right by specific embodiment in order to understand in order to preferably explain the utility model
The utility model is described in detail.
As depicted in figs. 1 and 2, the periphery of framework 11 is circular ring shape plate.The first sealing ring 14 is arranged in the periphery of circular ring shape plate,
The outer diameter of first sealing ring 14 can cooperate the internal diameter of existing storm sewer, completely cut off the two sides up and down of the utility model.First is close
Seal 14 can be using quick hardening cement, marine glue, leak stopping king etc..In order to increase fixing intensity, can be arranged in 1 side wall of fixed frame
Fixed frame 1 is fixed in storm sewer by through-hole using bolt by through-hole.
The outer diameter for being also possible to the first sealing ring is larger, closed when the docking of the pipe of cement of two storm sewers
Clamp the top and bottom of the first sealing ring 14.
Stripe board is set at the diameter of circular ring shape plate, is provided with connector 13 below stripe board, this where stripe board
Diameter divides fixed plate 1 for Liao Liangge semicircle area, each semicircle area include one crossed by circular ring shape plate and stripe board half
Circular through hole.
Movable plate 2 includes baffle 24 and shaft 21, and shaft 21 and connector 13 are rotatablely connected, can be according to the number of shaft 21
The number of amount setting rotor 13.With reference to Fig. 3, the movable plate 2 in left side includes the shaft 21 that middle position is arranged in, right
The movable plate 2 of side includes two shafts 21 for being separately positioned on the two sides up and down of Fig. 3.Diameter where shaft 21 and stripe board
In parallel.The shaft 21 of two movable plates 2 can also be all disposed within to the two sides up and down for being biased to Fig. 3, the middle part of such stripe board is just
It can be not provided with connector 13.It will attenuate in the middle part of stripe board and even cancel, so that the utility model allows after movable plate 2 is opened
By flow it is bigger.
The shaft 21 of movable plate 2 is all set to the semicircle area where movable plate 2 in Fig. 3, also can be set another in fact
A semicircle area.Two movable plates 2 can be bonded closer when rotating downward, also be conducive to promote whole flow in this way.
In Fig. 2, baffle 24 is proximal end close to one end of shaft 21, and the other end is distal end.Shaft 21 and baffle 24 are by connecting
Plate 22 connects.It actually can not also include connecting plate 22, the arrangement identical with 24 level height of connecting plate of shaft 21.
Connecting plate 22 is connected to the proximal end of baffle 24, and the two shape is at L-shaped, actually also can connect in baffle 24
Portion.Or the plate-shaped in the not instead of Fig. 2 of the section of baffle 24, triangle or thicker rectangle, connecting plate is not needed in this way
In the case where 22, the upper surface of shaft 21 and baffle 24 relative position are still as shown in Figure 2, and the position of shaft 21 is lower than baffle
The upper surface of 24, while in vertical plane, except baffle 24 and the binding face of framework 11.So set, baffle 24 is to turn
When axis 21 is axis rotation fitting framework 11, there is the wiping action of the miniature deformation of a horizontal direction.
The second sealing ring 25 is arranged in baffle 24 above, and below seal 12 is arranged in corresponding position in framework 11.Seal 12
Protrude from framework 11 in the following, primarily to abrasion, defect when can have certain reparation surplus, guarantee entire 12 He of seal
Second sealing ring 25 is bonded tightly.
Baffle 24 can also be trapezoidal in the section of Fig. 2 view in fact, the short bottom length in trapezoidal upper bottom.And 11 upper half of framework
The also inclination from becoming that trapezoidal two waist can be cooperated vertically of the side wall of circular through hole.Trapezoidal two are arranged in second sealing ring 25
Waist.Seal 12 is also disposed on the sloped sidewall of framework 11.
It is less than 1g/cm including density for cavity 23 or baffle 24 inside baffle 243Part, such as distal end is using water-fast
Rubber, or whole includes one layer of water-fast plastics.The corresponding buoyancy of the displacement of baffle 24 in this way, greater than the gravity of itself.When
When refluence, baffle 24 seals under buoyancy.Partition provided by the utility model has completely cut off storm sewer.
When proper drainage, baffle 24 rotates down under the effect of gravity, at least one lower part of two baffles 24 in left and right
Anticollison block is set.In order to limit the rotational angle of baffle 24, anti-baffle plate 24 turns from the semicircle area of the side of shaft where itself
Movement dead is generated after to other side semicircle area, the gag lever post for two movable plates 2 in left and right is respectively set on connector 13.
Two such movable plate 2 needs that the anticollison block corresponding to gag lever post is respectively set, and anticollison block can be in baffle 24 in the following, can also
In 22 inside of connecting plate.
Upper embodiment is only the preferred embodiment of the utility model, for those of ordinary skill in the art, according to this reality
With novel thought, there will be changes in the specific implementation manner and application range, and this specification should not be construed as to this
The limitation of utility model.
