Description

Technical Field

[0001] The utility model relates to the field of municipal drainage facilities, in particular to an eccentric rainwater outlet component. Background Art

[0002] The traditional rainwater pipe system consists of rainwater inlets and inspection wells. The rainwater inlets are water collection facilities, which are arranged in sections every 30-40 meters along the road to collect rainwater along the road. Inspection wells must be set up in conjunction with the rainwater inlets. The rainwater inlets and inspection wells are connected by rainwater inlet connecting pipes. The rainwater pipe connecting pipes change with the position of the inspection wells.

[0003] In the process of rainwater pipe construction, there is a phenomenon that the rainwater main pipe is buried deep. Because the rainwater outlet connection pipe needs to be connected to the inspection well chamber, if the depth of the rainwater outlet is only increased, when the rainwater grate is damaged, it is easy to cause safety hazards, and the deep burial depth of the rainwater outlet is not easy to dredge and maintain. Utility Model Content

[0004] The purpose of the utility model is to provide an eccentric gully assembly to address the defects of the prior art. To cope with the situation where the rainwater main is buried at a great depth, the structure of the gully combined with an eccentric well is adopted. The water collected by the gully is discharged through the eccentric well for a secondary drop and then enters the well chamber of the inspection well through a connecting pipe, thereby reducing the buried depth of the gully to improve safety.

[0005] In order to achieve the above purpose, the following technical solutions are adopted:

[0006] An eccentric rainwater inlet assembly comprises:

[0007] A rainwater outlet with a grate at the top opening;

[0008] The eccentric well is arranged horizontally and spaced apart from the rainwater outlet. One side of the eccentric well is connected to the rainwater outlet through a water inlet, and the other side is connected to the inspection well through a connecting pipe. Vertically, the bottom surface of the rainwater outlet is located between the bottom surface of the eccentric well and the water inlet, and the connecting pipe is located between the water inlet and the bottom surface of the eccentric well.

[0009] Furthermore, the bottom end of the water delivery port and the bottom surface of the rainwater outlet are spaced apart in the vertical direction, and a sludge well is formed between the bottom surface of the rainwater outlet and the water delivery port.

[0010] Furthermore, the water inlet is connected to the top of the eccentric well, and the connecting pipe is connected to the bottom of the eccentric well.

[0011] Furthermore, a grille is installed in the water inlet.

[0012] Furthermore, the top and bottom ends of the eccentric well are both blocked, the top end of the water delivery port is flush with the end surface of the top end of the eccentric well, and the bottom end of the connecting pipe is flush with the end surface of the bottom end of the eccentric well.

[0013] Furthermore, the eccentric well is located on a side of the rainwater inlet close to the inspection well, and the axis of the eccentric well is vertically distributed.

[0014] Furthermore, a groove is provided at the top of the inspection well, and the grate is embedded in the groove.

[0015] Furthermore, a vertical edge stone is provided on one side of the grate, the vertical edge stone abuts against the grate to constrain the position of the grate, and the vertical edge stone is combined with the top of the inspection well to form a groove for accommodating the inspection well.

[0016] Furthermore, the axis of the connecting pipe is arranged obliquely, and one end of the connecting pipe connected to the inspection well is lower than one end of the connecting pipe connected to the eccentric well.

[0017] Furthermore, an anti-seepage layer is provided at the bottom of the rainwater outlet and the bottom of the eccentric well, and the sides of the rainwater outlet and the sides of the eccentric well are both waterproof structures.

[0018] Compared with the prior art, the utility model has the following advantages and positive effects:

[0019] (1) In order to solve the problem that the use of deep-buried rainwater outlets is prone to safety hazards when the rainwater main is buried deep, a rainwater outlet combined with an eccentric well structure is adopted. The water collected by the rainwater outlet flows through the eccentric well for a second drop, and then enters the well chamber of the inspection well through a connecting pipe, thereby reducing the buried depth of the rainwater outlet to improve safety.

[0020] (2) The depth of the stormwater inlet is reduced, which makes it easier to clear silt, maintain and inspect than traditional stormwater inlets with large burial depths, thus saving the cost of clearing silt before the rainy season.

[0021] (3) By setting a height difference between the water inlet and the bottom of the rainwater outlet, a sludge well is formed at the bottom of the rainwater outlet, reducing the amount of mud and gravel transported to the inspection well and reducing the risk of blockage in the drainage system. In addition, grates are set to achieve initial filtration, and large volumes of garbage are intercepted by the grille to achieve secondary filtration, promoting smooth drainage.

[0025] In a typical implementation of the present invention, Figure 1 As shown, an eccentric rainwater inlet assembly is proposed.

[0026] When the buried depth of the rainwater main pipe is large, it is usually necessary to build a deeper rainwater outlet 3, which directly increases the buried depth of the rainwater outlet 3. On the one hand, when the grate 1 of the rainwater outlet 3 is damaged, a safety accident is prone to occur due to the large buried depth. On the other hand, it is inconvenient to dredge the rainwater outlet 3 with a large buried depth. Based on this, this embodiment provides an eccentric rainwater outlet assembly, establishes an eccentric well 5 connected to the rainwater outlet 3, and uses the eccentric well 5 to connect to the inspection well 8 through the connecting pipe 7, so as to meet the vertical depth of the water flow path, reduce the buried depth of the rainwater outlet 3, reduce safety hazards and facilitate dredging.

[0027] Below, the eccentric gully assembly is described in detail with reference to the accompanying drawings.

[0028] See also Figure 1 The eccentric gully assembly includes a gully 3 and an eccentric well 5. The top opening of the gully 3 is provided with a grate 1 for collecting and filtering rainwater. Considering the convenience and safety of daily use, it is ensured that rainwater can be effectively collected and impurities can be filtered out. The eccentric well 5 is arranged horizontally with the gully 3 to form a certain eccentric distance. This makes the connection between the gully 3 and the inspection well 8 more flexible, and there is no need to directly increase the burial depth of the gully 3. A water inlet 9 is provided on one side of the eccentric well 5 for connecting the gully 3 so that rainwater can flow smoothly into the eccentric well 5. The other side of the eccentric well 5 is connected to the inspection well 8 through a connecting pipe 7 to realize the discharge of rainwater.

[0029] It is understandable that the horizontal spacing between the eccentric well 5 and the rainwater inlet 3 can be set to 24 cm, 30 cm, etc., and configured according to actual needs to form an eccentric arrangement in the horizontal direction.

[0030] In the vertical layout, the bottom surface of the rainwater inlet 3 is located between the bottom surface of the eccentric well 5 and the water inlet 9, and the connecting pipe 7 is located between the water inlet 9 and the bottom surface of the eccentric well 5, so that the water entering the eccentric well 5 through the water inlet 9 can be smoothly discharged from the connecting pipe 7. This layout ensures that before the rainwater flows into the inspection well 8, it will first fall twice in the eccentric well 5, reducing the water flow speed and reducing the impact on the inspection well 8. At the same time, since the connecting pipe 7 is located below the eccentric well 5, the problem caused by directly increasing the burial depth of the rainwater inlet 3 is also avoided.

[0031] By adopting the eccentric well 5 structure, the rainwater inlet 3 does not need to be buried too deeply underground, which reduces the potential safety hazard caused by damage to the rainwater grate 1 and also facilitates future dredging and maintenance work.

[0032] In addition, the large vertical drop between the conventional rainwater inlet 3 and the rainwater main pipe will cause a large drop and produce an impact effect if the rainwater inlet 3 and the inspection well 8 are directly established through the connecting pipe 7. In this embodiment, the secondary drop of rainwater in the eccentric well 5 also helps to reduce the impact of water flow on the inspection well 8, further improving the safety of the drainage system.

[0033] By optimizing the connection mode between the rainwater inlet 3 and the inspection well 8, the additional engineering investment caused by raising the well chamber of the inspection well 8 is avoided, thereby achieving engineering cost savings.

[0034] The bottom end of the water inlet 9 and the bottom surface of the rainwater outlet 3 are vertically spaced apart to form a sludge well between the bottom surface of the rainwater outlet 3 and the water inlet 9; this helps to precipitate mud and impurities at the bottom of the rainwater outlet 3, reduce the amount of mud and gravel that enter the inspection well 8, and reduce the risk of blockage in the drainage system.

[0035] The water inlet 9 is connected to the top of the eccentric well 5, and the connecting pipe 7 is connected to the bottom of the eccentric well 5. The top and bottom of the eccentric well 5 are both blocked. The top of the water inlet 9 is flush with the top end face of the eccentric well 5, so that the water inlet 9 can be built at the same time as the eccentric well 5, reducing the construction difficulty. The bottom end of the connecting pipe 7 is flush with the bottom end face of the eccentric well 5, so that the connecting pipe 7 can be well supported by the bottom end face of the eccentric well 5, thereby improving its stability; ensuring that rainwater can smoothly enter the eccentric well 5, and form a secondary waterfall in the well, reducing the water flow speed, and then smoothly enter the inspection well 8 through the connecting pipe 7.

[0036] A grille 4 is installed in the water inlet 9 to intercept large-volume garbage, achieve secondary filtration, and ensure smooth drainage. A vertical edge stone 2 is provided on one side of the grate 1 to constrain the position of the grate 1 and ensure the stability of the rainwater outlet 3 structure.

[0037] The axis of the connecting pipe 7 is arranged tilted, and one end of the connecting pipe 7 connected to the inspection well 8 is lower than the other end of the connecting pipe 7 connected to the eccentric well 5; ensuring that rainwater can be discharged smoothly, while lowering the position of one end of the connecting pipe 7 connected to the inspection well 8, which helps to reduce the accumulation of water in the eccentric well 5.

[0038] The bottom of the rainwater inlet 3 and the bottom of the eccentric well 5 are provided with an anti-seepage layer, and the sides of the rainwater inlet 3 and the sides of the eccentric well 5 are waterproof structures 6. The bottom and sides of the rainwater inlet 3 and the eccentric well 5 are waterproofed and anti-seepage treated to ensure the stability and durability of the structure.

[0039] By setting up the sedimentation well and the grille 4, the mud and garbage entering the inspection well 8 are effectively reduced, the risk of clogging of the drainage system is reduced, and the smooth drainage is promoted. Not only the safety and maintenance convenience of the rainwater drainage system are improved, but also the drainage efficiency is improved.

[0040] like Figure 1As shown, the vertical height of the rainwater outlet 3 in this embodiment is less than 1300mm, and the diameter of the rainwater outlet 3 is 360mm. If a rectangular cross-section is adopted, the horizontal width of the rainwater outlet 3 is 360mm, wherein the depth of the sludge well is 300mm; the water delivery port 9 is a circular through-hole structure, and the diameter of the water delivery port 9 can be set to 500mm. The side wall thickness of the eccentric well 5 is 240mm, that is, the spacing between the eccentric well 5 and the rainwater outlet 3 is 240mm; the top thickness of the eccentric well 5 is 240mm, and the diameter of the eccentric well 5 is 360mm.

[0041] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
