Description

Technical Field

[0001] The utility model relates to a municipal drainage structure, in particular to a rainwater outlet using a filter basket. Background Art

[0002] During heavy rain, the flow rate on urban roads surges, and road drainage facilities face great pressure. If the road runoff cannot be quickly removed, it is very easy to cause urban waterlogging, causing huge losses to the social economy and seriously threatening urban safety. On the other hand, a large amount of pollutants accumulate on the road surface, such as particulate matter, oil, salt, nitrogen, phosphorus, toxic substances and domestic garbage, which are washed into the drainage pipes or directly enter the surface water environment with surface runoff during rainfall, causing serious pollution to the water environment. However, the traditional road drainage method does not solve the runoff pollution problem well in the process of road surface rainwater confluence. Therefore, it is necessary to add physical or ecological interception measures on the basis of the traditional drainage system to control road runoff pollution and reduce the harm to the water environment. The technical improvement of scattered road rainwater inlets provides a possible way to control road runoff pollution. The rainwater inlet is an important auxiliary structure for collecting rainwater in the rainwater pipe system, which consists of a water inlet grate, a well body and a branch pipe. The rainwater inlet is the main way to collect and discharge road rainwater, so the reasonable design of the rainwater inlet is the key to the removal of rainwater from urban road pavement runoff.

[0003] In the prior art, there is a Chinese utility model patent with application number 202222698854.4 and application name "A fast-installed standardized environmentally friendly rainwater outlet", which includes a rainwater outlet located below the road surface, a rainwater grate is provided on the top of the rainwater outlet, a drainage outlet is provided on the side wall of the rainwater outlet, the drainage outlet is connected to the inside of the rainwater outlet, a filter basket is detachably connected to the rainwater outlet, and a water outlet is provided on the side wall of the filter basket. This rainwater outlet does not use filter bricks, and the filtering effect is poor, but the use of a hollow filter basket improves the filtering effect.

[0004] The Chinese utility model patent with application number 202123284883.8 and application name "Surface Source Pollution Processor Box" has a box body formed in one step by resin concrete. The top of the box body has an opening. The inside of the box body has a cavity for placing the surface source pollution processor inner tank. A drain port is provided on the side wall of the cavity. The drain port is located at the lower part of the box body. A drainage pipe is connected to the drain port. The inner side of the edge of the opening has a first step and a second step for carrying the surface source pollution processor inner tank. The second step is lower than the first step. An outer frame is provided on the outer side of the edge of the opening. A water filter plate is embedded in the first step. Although filter bricks are used and the filtration effect is good, the filtration cost is high.

[0005] Therefore, there is an urgent need for a rainwater outlet that takes into account filtering effect, efficiency and cost. Utility Model Content

[0013] Furthermore, the depth of the blind hole is greater than the thickness of the rainwater inlet body after thinning.

[0014] Furthermore, the material of the rainwater inlet body is resin concrete.

[0015] Furthermore, the cross section of the blind hole is a waist-shaped hole as a whole.

[0026] Embodiment 1:

[0027] like Figure 1 A rainwater outlet using a filter basket is shown, comprising a rainwater outlet body 1, a rainwater grate 2 covering the rainwater outlet body 1, a sewage intercepting basket 3 built into the upper part of the rainwater outlet body 1, a filter basket 4 placed on the bottom surface of the sewage intercepting basket 3, and a filter net 5 located above the filter basket 4 is arranged on the inner wall of the sewage intercepting basket 3.

[0028] The rainwater outlet body 1 is a shell, and the rainwater grate 2 can be opened or closed. The lower part of the rainwater outlet body 1 is provided with a pipe connection hole 6, and the pipe connection hole 6 is used to connect other drainage pipes. The structures of the rainwater outlet body 1 and the rainwater grate 2 are prior art and will not be repeated here.

[0029] Among them, the sewage interception basket 3 is detachably connected to the upper part of the rainwater outlet body 1, and the top surface of the sewage interception basket 3 is open and the bottom surface is provided with a drainage hole. In addition, drainage holes can also be provided on the side wall of the sewage interception basket 3, and a filter basket 4 or a filter brick can be placed on the side wall. The structure of the sewage interception basket 3 can refer to the prior art, such as the filter basket in the Chinese utility model patent with application number 202123221486.6 and application name "A Road Rainwater Inlet Structure".

[0030] Among them, the filter net 5 is detachably connected to the sewage interception basket 3; the filter basket 4 can be placed on the bottom of the sewage interception basket 3, and the filter basket 4 has at least one adsorption layer made of building red brick particles, which can be placed in the filter basket 4.

[0031] Specifically, a circle of protrusions 31 is provided above the inner wall of the sewage intercepting basket 3, and the edge of the filter screen is placed on the protrusions 31. Or other fasteners such as locks or bolts and nuts are used to install the filter screen 5 on the sewage intercepting basket 3. The filter screen 5 is detachable. A filter basket 4 is placed on the bottom surface of the sewage intercepting basket 3, and the top opening of the filter basket 4 is convenient for taking and placing the adsorption layer. The filter basket 4 can directly hold building red brick particles, or the building red bricks can be concentrated into a bag, and then the bag is placed in the filter basket 4. When in use, rainwater passes through the rainwater grate 2, the filter screen 5, and the filter basket 4 to reach the drainage hole on the bottom surface of the sewage intercepting basket 3, and then flows into the lower part of the rainwater outlet body 1, and then transferred through the pipe connection hole 4.

[0032] Preferably, the material of the other adsorption layers is any one of ceramic rings, volcanic ash, activated carbon, and architectural red bricks. Different materials have different advantages and adsorption capacities, and a variety of materials can be used for filtering.

[0033] Embodiment 2:

[0034] Based on the first embodiment, Figure 2 The lower part of the shown rainwater outlet body 1 is provided with a plurality of concentric circles to be separated, and a plurality of blind holes 11 are arranged at intervals in the circumferential direction of each circle to be separated. The blind holes 11 thin the rainwater outlet body 1, and when a circle to be separated is selected to leave the rainwater outlet body 1 under the action of external force, a pipe connecting hole 6 is formed.

[0035] The outer surface of the lower part of the rainwater outlet body 1 is provided with a plurality of blind holes 11, which reduce the strength of the rainwater outlet body 1, but do not make the lower part of the rainwater outlet body 1 water permeable like a through hole. Because the pipe connection hole on the rainwater outlet in the prior art is different according to the usage scenario, it is necessary to select a pipe connection hole of a suitable diameter to connect the external drain pipe. A traditional rainwater outlet body 1 only has a pipe connection hole under one diameter, and the diameter of the pipe connection hole is generally formulated according to relevant standards, such as a diameter of 100, 200, or 300 mm. If a rainwater outlet body 1 has the ability to provide pipe connection holes 4 of different diameters, selecting a pipe connection hole 4 to be used on site according to the on-site usage scenario avoids the need to carry or provide different rainwater outlet bodies 1, saving time. And if it is a small-diameter pipe connection hole 6 when used for the first time, the rainwater outlet body 1 can also provide a large-diameter pipe connection hole 6 again.

[0036] When in use, the circle to be separated is determined as needed, and an external force such as a hammer or a hand can be used to tear the circle to be separated from the rainwater inlet body 1.

[0037] Preferably, the depth of the blind hole 11 is greater than the thickness of the gully body 1 after thinning.

[0038] Preferably, the material of the rainwater inlet body 1 is resin concrete.

[0039] Preferably, the cross section of the blind hole 11 is a waist-shaped hole as a whole, that is, a long strip-shaped hole as a whole.

[0040] Embodiment three:

[0041] Based on the second embodiment, Figure 3 As shown, the material of the gully body 1 is resin concrete. The original wall thickness AD of the gully body 1 is expressed as 5hcm, and the depth AC of the blind hole is at least 3hcm, so that the gully body 1 is thinned to CD = 2hcm. In the circumferential direction of the separation circle, the length of the blind hole is 3hcm, and 2hcm is reserved as an interval between the two blind holes AB. The value of 5h can be determined by measurement and other means.

[0042] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
