Description

Technical Field

[0001] The utility model relates to a municipal drainage structure, in particular to a main structure of a rainwater outlet. 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, the Chinese utility model patent with application number 202222698854.4 and application name "A fast-installed standardized environmentally friendly rainwater outlet" and the Chinese utility model patent with application number 202123284883.8 and application name "Surface source pollution treatment box" both have a pipe connection hole with a diameter opened in one rainwater outlet. However, in actual construction, the diameter of the outer pipe is often determined on site, and the diameter of the outer pipe to be connected to the pipe connection hole is fixed and unique, so different rainwater outlets need to be brought to the site to select the rainwater outlet with the appropriate diameter.

[0004] Therefore, there is an urgent need for a rainwater inlet that provides pipe connection holes with multiple diameters. Utility Model Content

[0005] The utility model aims to provide a rainwater outlet which provides pipe connecting holes with multiple diameters.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A rainwater inlet main structure comprises a rainwater inlet main shell, and a pipe connection hole is arranged at the lower part of the rainwater inlet main shell;

[0008] A plurality of concentric circles to be separated are arranged at the lower part of the rainwater outlet body, and a plurality of blind holes are arranged at intervals in the circumferential direction of each circle to be separated. The blind holes reduce the thickness of the outer shell of the rainwater outlet body, and the pipe connection hole is formed when a circle to be separated is selected to leave the outer shell of the rainwater outlet body under the action of external force.

[0009] Furthermore, the depth of the blind hole is greater than the thickness of the thinned outer shell of the rainwater inlet body.

[0010] Furthermore, along the circumference of the ring to be separated, the length of the blind hole is greater than the length of the interval between the two blind holes.

[0011] Furthermore, the material of the main shell of the rainwater inlet is resin concrete.

[0012] Furthermore, the cross section of the blind hole is a waist-shaped hole as a whole.

[0013] In the above technical solution, the utility model has the following beneficial effects:

[0014] The utility model provides a rainwater outlet main structure that can provide pipe connection holes of multiple diameters. By improving the outer shell of the rainwater outlet main body, it does not provide pre-opened pipe connection holes. Instead, multiple circles of blind holes are prefabricated on the rainwater outlet main body shell, and the blind holes thin the wall thickness of the rainwater outlet main body shell without piercing the rainwater outlet main body shell. Only when the size of the pipe connection hole is determined, a circle of blind holes corresponding to the size and the intervals on the circle of blind holes are torn off from the rainwater outlet main body shell under the action of external force, and the pipe connection hole is configured on site.

[0020] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0021] It should be noted that the terms "above", "one end", "upper", etc. used in this article indicate the orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description. Similar expressions are only for the purpose of illustration, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention; in addition, the terms "one part", "two parts", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0022] Embodiment 1:

[0023] like Figure 1 The lower part of the rainwater outlet main body shell 1 shown is provided with a plurality of concentric to-be-separated circles, and a plurality of blind holes 11 are arranged at intervals in the circumferential direction of each to-be-separated circle. The blind holes 11 thin the rainwater outlet main body shell 1, and when a to-be-separated circle is selected to leave the rainwater outlet main body shell 1 under the action of external force, a pipeline connection hole is formed.

[0024] The outer surface of the lower part of the main shell 1 of the rainwater outlet is provided with a plurality of blind holes 11, which reduce the strength of the main shell 1 of the rainwater outlet, but do not make the lower part of the main shell 1 of the rainwater outlet water-permeable like a through hole. Because the pipe connection hole on the rainwater outlet in the prior art is different according to the use scenario, for example, a pipe connection hole of different diameters is selected to connect to the external drain pipe. A traditional rainwater outlet main shell only has a pipe connection hole of a certain diameter, and the diameter of the pipe connection hole is generally formulated according to relevant standards, for example, the diameter is 100, 200, 300 mm. If a rainwater outlet main shell 1 has the ability to provide pipe connection holes of different diameters, the work of carrying or providing different rainwater outlet main shells 1 can be avoided according to the on-site use scenario. If it is a small-diameter pipe connection hole when used for the first time, the rainwater outlet main shell 1 can also provide a large-diameter pipe connection hole again.

[0025] 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 main casing 1 of the rainwater inlet.

[0026] Preferably, the depth of the blind hole 11 is greater than the thickness of the thinned rainwater outlet main body shell 1 .

[0027] Preferably, the material of the main shell of the rainwater inlet 1 is resin concrete.

[0028] 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.

[0029] Embodiment 2:

[0030] Based on the first embodiment, Figure 2 As shown, the material of the main shell 1 of the rainwater inlet is resin concrete. Assuming that the original wall thickness AD of the main shell 1 of the rainwater inlet is expressed as 5hcm, the depth AC of the blind hole is at least 3hcm, so that the main shell 1 of the rainwater inlet is thinned to CD = 2hcm. In the circumferential direction of the circle to be separated, the length of the blind hole is 3hcm, and 2hcm is reserved as an interval between the two blind holes AB. 5h is the original wall thickness AD of the main shell 1 of the rainwater inlet, which can be known by measurement and other means, so as to obtain the specific value of h.

[0031] 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.
