Specific embodiment
Backward flowing preventing device this utility model provided below in conjunction with the drawings and specific embodiments and sinking containing the device Shallow lake pond is described in further detail.With reference to following explanation and claims, advantages and features of the present utility model will become apparent from. It should be noted that, accompanying drawing in the form of simplifying very much and uses non-accurately ratio, only conveniently, lucidly to aid in Illustrate the purpose of this utility model embodiment.
The structural representation of the backward flowing preventing device 200 for referring to Fig. 2 and Fig. 3, Fig. 2 and providing for one embodiment of this utility model Figure, decomposing schematic representations of the Fig. 3 for Fig. 2.Backward flowing preventing device 200 is a variable cross-section hollow pipe, is followed successively by into water from top to bottom and is connected Section 210, section divergent segment 220, straight length 230, section converging transition 240, water outlet linkage section 250, are provided with straight length 230 Ball float 260, the internal diameter with diameter greater than water inlet linkage section 210 of ball float 260 in backward flowing preventing device 200 are additionally provided with ball float and hang Put component.Wherein, ball float suspension component blocks water outlet linkage section 250 for preventing ball float 260 from dropping, so that current smoothly lead to Cross.In figs. 2 and 3, ball float suspension component is filter screen 271, and for example and without limitation, the version of filter screen 271 is:1) The crisscross formation of the filaments such as iron wire, fibre bundle containing poroid fabric, surrounding is fixed by frame;2) central aperture Plastics, the thin slice of alloy etc..Filter screen 271 can prevent ball float 260 from falling and block water outlet linkage section 250, and water can be made smooth Pass through.When water is entered in backward flowing preventing device 200 by water outlet linkage section 250, ball float 260 slowly floats, until block into water connecting Section 210 is connect, in the presence of hydraulic pressure, ball float 260 is closely sticked together with water inlet linkage section 210 or section divergent segment 220, effectively Control water is flowed out by linkage section 210 of intaking.
As seen from the above description, ball float 260 is set and ball float suspends the backward flowing preventing device 200 of component, current list can be made To circulation, so as to anti-water-stop body pours in down a chimney.
Ball float suspension component 270 it is another preferred embodiment, as shown in figure 4, on section divergent segment 220 arrange filter Cylinder 272, filter cylinder 272 is fixed on section divergent segment 220, and the side wall of filter cylinder 272 and base plate arrange multiple osculums, ball float 260 It is placed in filter cylinder 272.During nominal situation, ball float 260 is located at the bottom of filter cylinder 272, and water body is by the osculum stream on filter cylinder 272 Go out, then discharged by water outlet linkage section 250;When water pours in down a chimney into backward flowing preventing device 200, ball float 260 floats and blocks into water Linkage section 210.It is preferred embodiment that filter cylinder 272 is fixed on section divergent segment 220, as an example by hanging buckle structure, Hanging buckle structure can be that notch or suspension ring are arranged on section divergent segment 220, arrange hook, be so conducive to taking on filter cylinder 272 Lower filter cylinder 272 is cleaned.
Ball float suspension component 270 it is another preferred embodiment, as shown in figure 5, in section divergent segment 220 or straight length 230 arrange rope 273, and one end of rope 273 is fixed on section divergent segment 220 or straight length 230, and the other end is fixed on ball float On 260.Fix for the ease of rope 273, suspension ring can be set on section divergent segment 220 or straight length 230.The length of rope is full Foot:Ball float 260 does not block 250 water outlet of water outlet linkage section when hanging, and when ball float 260 floats, can block into water linkage section 210. In order to be further described to the length of rope, incorporated by reference to Fig. 6, Fig. 6 be in Fig. 5 embodiment in different operating modes ball float position with Rope lengths schematic diagram.In Fig. 6, when ball float floats and blocks into water linkage section 210, the minimum length of rope 273 is labeled as H1;When ball float being sunk to blocking water outlet linkage section 210, the minimum length of rope 273 is H2;So rope 273 of ball float 260 Length need to meet condition:H1<H<H2, that is, rope 273 is met when water body pours in down a chimney, ball float 260 can float and block into water linkage section 210, in nominal situation, 260 without prejudice to water body of ball float flows out water outlet linkage section 250.Therefore, rope 273 and ball float are set 260, water body flow when both can guarantee that nominal situation can pour in down a chimney blocking river when river is in high water level, again with structure letter The good advantage of list, low cost, effect, meanwhile, with Fig. 2 compared with the embodiment shown in Fig. 4, it is right that setting rope 273 is also reduced Ball float suspends the cleaning of component.
In addition, 260 diameter of ball float is excessive, by drainage effect during impact nominal situation, 260 diameter of ball float is too small can not Ensure the sealing effectiveness between ball float 260 and water inlet linkage section 210 or section divergent segment 220.It is therefore preferable that be, ball float 260 1.1-1.5 times of a diameter of water inlet 210 internal diameter of linkage section.
This utility model additionally provides a kind of sedimentation tank 100, with reference to shown in Fig. 7 and Fig. 8, cell body one end of sedimentation tank 100 Connection water inlet pipe 110, other end connection outlet pipe 121, outlet pipe 121 are also associated with the backward flowing preventing device in previous embodiment 200.As shown in fig. 7, in nominal situation, Jing after 100 purified treatment of sedimentation tank, 130 Jing outlet pipes 121 of water flow into anti-down sewage Ball float 260 is kept apart by filling device 200, ball float addressing component with water outlet linkage section 250, makes water body smoothly flow out backward flowing preventing device 200, in outlet pipe 122.As shown in figure 8, in flood season operating mode, river water level goes up, under hydraulic pressure effect, river pours in down a chimney Enter in backward flowing preventing device 200, ball float 260 floats, and block into water linkage section 210, block the water body for pouring in down a chimney and enter sedimentation tank 100 In.Therefore, the sedimentation tank in the present embodiment, suspends component 270 by arranging ball float 260 and ball float, it is ensured that current can smoothly by 100 Jing backward flowing preventing devices 200 of sedimentation tank are entered in river, while can also block river enters precipitation by backward flowing preventing device 200 In pond 100, so as to prevent sedimentation tank 100 to overflow and pollute because river pours in down a chimney.
Illustrated, the backward flowing preventing device 200 set by sedimentation tank 100 shown in Fig. 7, Fig. 8 is needed, its ball float suspension Component is filter screen 271, certainly, has similar effect using aforesaid filter cylinder 272 and 273 version of rope, and here is not made Repeat.
Foregoing description is only the description to this utility model preferred embodiment, not any limit to this utility model scope Fixed, any change that the those of ordinary skill in this utility model field is done according to the disclosure above content, modification belong to right and want Seek the protection domain of book.
