Technical Field
[0001] The utility model relates to the technical field of drainage pipelines, and particularly to a buried drainage pipeline. Background Art
[0002] A drainage pipeline refers to a system composed of conduits and their ancillary facilities for collecting and discharging sewage, wastewater, and rainwater. It includes main pipes, branch pipes, and pipes leading to a treatment plant. Whether built on a street or anywhere else, as long as it serves a drainage function, it should be counted as a drainage pipeline.
[0003] A buried drainage pipeline is to bury the drainage pipeline into the ground or a building. It is inconvenient to clean the buried drainage pipeline when it is blocked after laying. Therefore, in the prior art, a filter cylinder is assembled at the water inlet end of the drainage pipeline to filter out sundries such as leaves and plastic bags. The filter cylinder needs to be regularly cleaned of the sundries inside. When it rains without timely cleaning, rainwater cannot be drained in time and water will accumulate on the road surface. Therefore, a buried drainage pipeline needs to be designed. Summary of the Utility Model
[0004] Aiming at the above technical problems, the purpose of the utility model is to overcome the problem that water accumulates on the road surface when the sundries in the filter cylinder are not cleaned in time in the prior art.
[0005] To achieve the above purpose, the utility model provides a buried drainage pipeline, including: a vertical drainage pipe, a connection sleeve coaxially and fixedly installed on the drainage pipe, a filter support plate assembled at the top end of the connection sleeve, an annular limiting member coaxially and fixedly installed on the inner wall of the drainage pipe, an upper filter cylinder located on the inner wall of the drainage pipe and having an open top and a protruding annular flange in contact with the upper surface of the annular limiting member, and an outer pipe sleeve coaxially and fittingly installed on the outer wall of the drainage pipe at the lower end and fixedly connected to the connection sleeve at the upper end. A drainage channel is formed by spacing the inner wall of the outer pipe sleeve from the outer wall of the drainage pipe;
[0006] At least one water inlet communicating with the drainage channel is penetrated through the connection sleeve, at least one water outlet communicating with the drainage channel and located below the annular limiting member is penetrated through the drainage pipe, and an annular drainage member for guiding the flow to avoid the water inlet is fixedly connected to the inner wall of the connection sleeve in a fitting manner.
[0007] Preferably, the bottom of the upper filter cylinder is connected by at least one connecting arm to a coaxially arranged lower filter cylinder with an open top, and the water outlet is located between the lower filter cylinder and the upper filter cylinder.
[0008] Preferably, a lifting handle is fixedly connected to the annular flange.
[0009] Preferably, the connecting sleeve includes a first ring plate portion with an inner edge fixedly connected to the upper end of the drain pipe, a first pipe sleeve portion with a lower end fixedly connected to the outer edge of the first ring plate portion, a second ring plate portion with an outer edge fixedly connected to the upper end of the first pipe sleeve portion, a second pipe sleeve portion with a lower end fixedly connected to the inner edge of the second ring plate portion, and a third ring plate portion with an inner edge fixedly connected to the upper end of the second pipe sleeve portion;
[0010] The annular drainage member is fixedly installed in a fitting manner on the inner wall of the second pipe sleeve portion. The water inlet is located on the first pipe sleeve portion, and the upper end of the outer pipe sleeve is fixedly connected to the third ring plate portion.
[0011] Preferably, an annular base is fixedly arranged in a fitting manner on the top of the third ring plate portion, and the filter support plate is clamped downward on the annular base.
[0012] Preferably, a ring plate member fixedly connected to the lower end of the outer pipe sleeve is welded coaxially and in a fitting manner on the outer wall of the outer pipe sleeve.
[0013] According to the above technical solution, a buried drainage pipe provided by the present utility model has the following beneficial effects during use:
[0014] First, when it rains and the water cannot be drained in time, when the water level rises above the water inlet, the water will flow into the drainage channel and then flow out through the water outlet. Even if the debris inside the upper filter cylinder has not been cleaned in time, the water can still be drained in time, avoiding the problem of water accumulation on the ground due to the inability to drain water.
[0015] Second, the annular drainage member can guide the water entering the connecting sleeve into the upper filter cylinder. When there is no problem of water being unable to be drained in time, the water will not flow into the water inlet, and the debris carried by the water will be intercepted by the upper filter cylinder.
[0016] Other features and advantages of the present utility model will be described in detail in the subsequent specific implementation part; moreover, the parts not involved in the present utility model are the same as or can adopt the existing technology. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The specific embodiments of the present utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present utility model, and are not used to limit the present utility model.
[0023] In the present utility model, unless otherwise stated, the directional terms such as "upper, lower, inner, outer" included in the terms only represent the orientation of the terms in the normal use state, or the common names understood by those skilled in the art, and should not be regarded as a limitation of the terms.
[0024] As Figure 1-2 shown, an embedded drainage pipe includes: a vertical drain pipe 1, a connecting sleeve 2 fixedly installed coaxially on the drain pipe 1, a filter support plate 3 assembled at the top end of the connecting sleeve 2, an annular limiting member 4 fixedly installed coaxially on the inner wall of the drain pipe 1, an upper filter cylinder 5 located on the inner wall of the drain pipe 1 and having an open top and a protruding annular flange in contact with the upper surface of the annular limiting member 4, and an outer pipe sleeve 6 whose lower end is coaxially and fittingly installed on the outer wall of the drain pipe 1 and whose upper end is fixedly connected to the connecting sleeve 2 in a fitting manner. A drainage channel 7 is formed by spacing the inner wall of the outer pipe sleeve 6 from the outer wall of the drain pipe 1;
[0025] At least one water inlet 10 communicating with the drainage channel 7 is provided through the connecting sleeve 2, and at least one water outlet 8 communicating with the drainage channel 7 and located below the annular limiting member 4 is provided through the drain pipe 1. An annular drainage member 9 for guiding the flow to avoid the water inlet 10 is fixedly connected to the inner wall of the connecting sleeve 2 in a fitting manner.
[0026] The upper filter cylinder 5 can intercept sundries such as leaves and plastic bags. When the upper filter cylinder 5 is already filled with sundries, the water flow rate through the upper filter cylinder 5 is very small at this time. If it is not cleaned in time, in case of rain, the water cannot be drained in time. When the water level rises above the water inlet 10, the water will flow into the drainage channel 7 and then flow out through the water outlet 8. Without cleaning the sundries inside the upper filter cylinder 5 in time, the water can still be drained in time, avoiding the problem of water accumulation on the ground due to the inability to drain water.
[0027] The annular drainage member 9 can allow the water entering the connecting sleeve 2 to enter the upper filter cylinder 5. When there is no problem of water not being discharged in time, the water will not flow into the water inlet 10, and the debris carried in the water will be intercepted by the upper filter cylinder 5.
[0028] The bottom of the upper filter cylinder 5 is connected by at least one connecting arm 11 to a coaxially arranged lower filter cylinder 12 with an open top, and the water outlet 8 is located between the lower filter cylinder 12 and the upper filter cylinder 5.
[0029] When the water level is higher than the water outlet 8, there will be water carrying some debris flowing into the drain pipe 1, and the lower filter cylinder 12 can filter the water discharged through the water outlet 8, thereby intercepting the debris passing through the water outlet 8.
[0030] A lifting handle 13 is fixedly connected to the annular flange.
[0031] For cleaning work, a hook can be used to hook the lifting handle 13 to take out the upper filter cylinder 5 and the lower filter cylinder 12 for cleaning.
[0032] The connecting sleeve 2 includes a first ring portion 14 with an inner edge fixedly connected to the upper end of the drain pipe 1, a first pipe sleeve portion 15 with a lower end fixedly connected to the outer edge of the first ring portion 14, a second ring portion 16 with an outer edge fixedly connected to the upper end of the first pipe sleeve portion 15, a second pipe sleeve portion 17 with a lower end fixedly connected to the inner edge of the second ring portion 16, and a third ring portion 18 with an inner edge fixedly connected to the upper end of the second pipe sleeve portion 17;
[0033] The annular drainage member 9 is fixedly installed in a fitting manner on the inner wall of the second pipe sleeve portion 17, the water inlet 10 is located on the first pipe sleeve portion 15, and the upper end of the outer pipe sleeve 6 is fixedly connected to the third ring portion 18.
[0034] The water outlet 8 is arranged away from the axis of the connecting sleeve 2. With the drainage effect of the annular drainage member 9, in the case of no blockage, the water will normally flow into the upper filter cylinder 5.
[0035] An annular base 19 is fixedly arranged in a fitting manner on the top of the third ring portion 18, and the filter support plate 3 is clamped downward on the annular base 19, or one end of the filter support plate 3 can be hinged to the annular base 19.
[0036] On the outer wall of the outer pipe sleeve 6, a ring piece 20 fixedly connected to the lower end of the outer pipe sleeve 6 is coaxially and fittingly welded.
[0037] The preferred embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solutions of the present invention, and these simple modifications all fall within the protection scope of the present invention.
[0038] In addition, it should be noted that the various specific technical features described in the above specific embodiments can be combined in any appropriate manner without conflict. To avoid unnecessary repetition, the present utility model will not further describe various possible combination methods.
[0039] In addition, any combination can be made between various different embodiments of the present utility model, as long as it does not violate the idea of the present utility model, it should also be regarded as the content disclosed by the present utility model.
