Description

TECHNICAL FIELD

[0001] The utility model relates to a drainage well, concretely relates to a drainage well structure with alleviating municipal road sundries pollution. BACKGROUND

[0002] The well lid is used for covering the deep well of the road or the home, prevents the person or the object from falling, is a kind of common municipal road facilities. According to material, it can be divided into metal well lid, high-strength fiber cement concrete well lid, resin well lid etc., generally adopts circular, can be used in green belt, sidewalk, motorway etc.

[0003] On the city street, the drainage well lid plays an important role when dredging the rainwater on the street. Especially in the summer of our country, rain is much, and the rainfall is big, if not promptly excluding the precipitation on the street, then the traffic of city will cause adverse effect. The existing well lid can realize the rapid discharge of rainwater, but the garbage such as branches, leaves and plastic bags on the street can easily enter the sewer, causing odor. Although the traditional drainage well is fast in drainage, but the large drainage hole leads to a large amount of sundries entering the drainage well pipeline system through the drainage hole at ordinary times, greatly increasing the cleaning workload of the sewer. UTILITY MODEL CONTENT

[0004] The utility model aims at overcoming the above-mentioned problems, providing a drainage well structure with alleviating municipal road sundries pollution, which can intercept impurities in water to the greatest extent and avoid the intercepted impurities from blocking the inlet of the drainage well, without affecting normal drainage work.

[0005] The utility model achieves the purpose by the following technical solutions:

[0009] The working principle of the above-mentioned drainage well structure with alleviating municipal road sundries pollution is as follows:

[0010] In operation, rainwater on the road flows to the well lid, and the well lid preliminarily intercepts impurities entrained by the rainwater, and leaves the impurities with a larger volume, while the rainwater and the impurities with a smaller volume pass through the first water inlet hole of the well lid into the well body and fall on the intercepting frame; since the size of the water filtering hole is smaller than the size of the drainage hole, the intercepting frame is equivalent to reducing the intercepting size, and the impurities are intercepted twice, so that the impurities with a size larger than the water filtering hole are intercepted, and finally the remaining impurities and rainwater pass through the water filtering hole and fall into the drainage well. Further, after a long time of interception, the impurities on the intercepting frame first block the water filtering hole and gradually accumulate; when the height of the accumulated impurities is level with the height of the first impurity discharge hole, since the size of the first impurity discharge hole is larger than the size of the water filtering hole, the impurities accumulated above are discharged from the first impurity discharge hole into the well body below, preventing the impurities from blocking the entire intercepting frame and affecting the normal drainage function.

Through the above structure, when the impurities are cleaned, the impurities above are dug out, and then the intercepting frame is taken out for cleaning, without the need to take out the intermediate frame; after cleaning, the top of the intercepting frame can be directly hung on the bottom of the intermediate frame, which is convenient and fast.

[0012] Further, a second impurity discharge hole is arranged on the side wall of the intermediate frame, and the size of the second impurity discharge hole is greater than or equal to the size of the drainage hole.

[0013] Further, the size of the first impurity discharge hole is greater than the size of the water filtering hole and smaller than the size of the second impurity discharge hole.

[0014] Through the above structure, the impurities with a size between the water filtering hole and the first impurity discharge hole are first discharged from the first impurity discharge hole, while the impurities with a size greater than the first impurity discharge hole continue to accumulate in the intercepting frame; when the height of the accumulated impurities is level with the height of the second impurity discharge hole, since the size of the second impurity discharge hole is greater than or equal to the size of the drainage hole, the second impurity discharge hole can discharge all the impurities falling down, preventing the impurities from blocking the entire intercepting frame and affecting the normal drainage function. The two-stage impurity discharge holes are arranged, which can intercept more impurities without affecting the normal drainage function.

[0015] Further, a first grabbing hole for grabbing is arranged on the side wall of the intermediate frame, so as to take out the intermediate frame.

[0016] Further, the top of the intermediate frame and the well lid are both provided with a plug-in hole, and the top of the well body is provided with a plug-in part of the plug-in hole.

[0017] Further, the length of the intermediate frame is greater than the length of the intercepting frame, and the width of the intermediate frame is greater than the width of the intercepting frame.

[0018] In one preferred scheme of the utility model, the side wall of the intercepting frame is provided with a second grabbing hole for grabbing, so as to take out the intercepting frame.

[0019] Compared with the prior art, the utility model has the following beneficial effects:

[0020] 1. The drainage well structure of the utility model can carry out secondary interception on impurities in rainwater through the filter hole smaller than the drainage hole, further avoids the impurities from falling into the well body, and can prolong the cleaning period of the well body.

[0021] 2.
