Description
Technical field
The utility model designs a kind of technical field of municipal drainage equipment, designs a kind of rainwater collection pool rainwater collection pool more specifically.
Background technology
Along with people are to the continuous exploitation of surface water, underground water, rainwater resource is also valued by the people gradually.In order to the environment protecting and keep people and water, Man & Nature to get along amiably and peacefully, people more and more pay attention to the Collection and use of rainwater, as set up rainwater collection pool, allow rainwater play due effect, thus alleviate the water resource of growing tension.And rainwater collection pool is generally be connected with municipal drainage pipeline.But when amount of rainfall is larger, when the water level of municipal drainage pipeline is higher, sewage wherein probably can flow backward in rainwater collection pool affects water quality in rainwater collection pool.
Utility model content
For the problems referred to above, the purpose of this utility model is to provide a kind of structure simple and can effectively prevents the rainwater in municipal drainage pipeline from flowing backward to device in rainwater collection pool.
The utility model is realized by following technical scheme.
A kind of rainwater collection pool anti-backflow device, described anti-backflow device comprises device body, described device body inside is hollow cavity, described device body side is provided with the water inlet be connected with municipal drainage pipeline, described device body opposite side is provided with the delivery port be connected with rainwater collection pool, cavity between described water inlet and delivery port arranges Packed dividing plate, described dividing plate has intercepted rainwater and has directly flow into water outlet from inlet end, described dividing plate is provided with an anti-overflow lip, to being arranged with a funnel shaped anti-overflow pipe on described anti-overflow lip, a hollow metal ball float is provided with in described anti-overflow pipe.
As this technical scheme further, the diameter of described metal ball float is greater than the diameter of the anti-overflow lip on baffle plate, and the diameter of described metal ball float is less than the diameter of anti-overflow pipe lower nozzle.
As this technical scheme further, the distance between bottom described anti-overflow pipe lower nozzle and device body is less than the length of floating ball diameter.
As this technical scheme further, the cavity bottom of described device body is provided with two pieces of vertical baffle plates, and described baffle plate is positioned at the below of anti-overflow pipe; Distance between described two pieces of baffle plates is not less than the diameter of metal ball float, and is not more than the diameter of the lower nozzle of anti-overflow pipe.
As this technical scheme further, bottom the internal cavity of described device body, be provided with resilient rubbber cushion, described resilient rubbber cushion is positioned at the below of anti-overflow pipe.
Beneficial effect: the utility model in use, be arranged between rainwater collection pool and municipal drainage pipeline, when municipal drainage pipeline water level is higher, the metal ball float of the inside floats and is sealed by overfall, prevent the sewage in municipal drainage pipeline from flowing backwards and enter rainwater collection pool, overfall reflux would not be caused like this.When water level is lower, can normally overflow.The utility model structure is simple, and anti-overflow effect is better, and can normally overflow, easy to use.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present embodiment.
Fig. 2 is the top view of the present embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail, can implements according to this with reference to manual word to make those skilled in the art.
As shown in Fig. 1, Fig. 2, a kind of rainwater collection pool anti-backflow device, comprises device body 1, and device body 1 inside is hollow cavity 2.The left and right left side cavity 2 of device body 1 being provided with below a water inlet 3(be connected with municipal drainage pipeline is only for Fig. 1, the description of Fig. 2, be not limited to the restriction to the utility model structure), the right side cavity 2 of device body 1 is provided with a delivery port be connected with rainwater collection pool 4, and the height of water inlet 3 is higher than the height of delivery port 4.Such design facilitates normal overflow to be that rainwater enters into rainwater collection pool from municipal drainage pipeline.
The top of the cavity 2 in device body 1 is provided with a breast board 11 straight down, and the length of breast board 11 is less than the height of cavity 2.Also be provided with the horizontal baffle 5 of a sealing in the cavity 2 of device body 1, the first end of horizontal baffle 5 is fixed on breast board, and the second end of horizontal baffle 5 is arranged on cavity 2 wall below water inlet 3.The existence of horizontal baffle 5 has intercepted rainwater and has directly flow into water outlet from municipal drainage pipeline.Horizontal baffle 5 offers a circular anti-overflow lip 6.To being arranged with a up-small and down-big funnel shaped anti-overflow pipe 7 on anti-overflow lip 6, the diameter of the upper orifice of anti-overflow pipe 7 is identical with the diameter of anti-overflow lip 6.Distance between the lower nozzle of anti-overflow pipe 7 and the bottom of cavity 2 is less than the diameter of stainless steel floating ball 8.Be placed with a hollow stainless steel floating ball 8 in anti-overflow pipe 7, ball float uses stainless steel, can play anticorrosive property strong, about aging-resistant.The diameter of hollow stainless steel floating ball 8 is greater than the diameter of the through hole on baffle plate, and the diameter of described metal ball float is less than the diameter of anti-overflow pipe lower nozzle.The distance be provided with on bottom cavity 2 immediately below anti-overflow pipe 7 between two pieces of baffle plate 10, two baffle plates 10 straight up equals the diameter of anti-overflow pipe 7 lower nozzle.Distance between the lower nozzle of breast board 10 and anti-overflow pipe 7 is less than the radius of stainless steel floating ball 8.A resilient rubbber cushion 9 is provided with on bottom cavity 2 between two baffle plates 10.Resilient rubbber cushion 9 to stainless steel floating ball, can play the effect of buffering.
The utility model in use, be arranged between rainwater collection pool and municipal drainage pipeline, when municipal drainage pipeline water level is higher, the stainless steel floating ball of the inside floats and is sealed by overfall, prevent the sewage in municipal drainage pipeline from flowing backwards and enter rainwater collection pool, overfall reflux would not be caused like this.When water level is lower, can normally overflow.The utility model structure is simple, and anti-overflow effect is better, and can normally overflow, easy to use.
Although embodiment of the present utility model is open as above, but it is not restricted to listed in manual and embodiment utilization, it can be applied to various applicable field of the present utility model completely, for those skilled in the art, can easily realize other amendment, therefore do not deviating under the universal that claim and equivalency range limit, the utility model is not limited to specific details and illustrates here and the legend described.
