Description

Technical Field

[0001] The invention relates to the technical field of drainage pipe structures, and in particular to a sewage drainage pipe. Background Art

[0002] Stormwater pipes and sewage pipes are the two main types of urban underground pipeline systems. Stormwater pipes are specially used to collect and transport natural precipitation, such as rainwater, melted snow, etc. These waters are usually clean and not seriously polluted. Sewage pipes are used to collect and transport domestic sewage and industrial wastewater, which usually contain various organic matter, chemicals and other pollutants.

[0003] In the prior art, sewage pipes and rainwater pipes are usually set separately. Since domestic wastewater often contains a large amount of debris and sediments, sewage pipes are prone to blockage. In order to avoid the above situation and maximize the use of rainwater in rainwater pipes for dredging, a sewage drainage pipe is proposed to solve the above problem. Summary of the invention

[0004] The purpose of the present invention is to provide a sewage drainage pipeline in view of the above-mentioned shortcomings.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solution: a sewage drainage pipeline, comprising:

[0006] A plurality of pipelines are spliced ​​together in sequence, wherein a partition is horizontally arranged inside the pipeline, and the partition separates the pipeline into a sewage pipe and a rainwater pipe;

[0007] The partition is provided with a plurality of connecting holes, and a one-way plug is provided in each of the connecting holes. A liquid injection groove corresponding to the connecting hole is provided in the partition, and a water injection port for connecting the liquid injection groove and the rainwater discharge pipe is also provided on the partition, so that rainwater in the rainwater discharge pipe enters the sewage discharge pipe and washes the sediment at the bottom of the sewage discharge pipe;

[0008] A blocking portion for blocking the rainwater discharge pipe is provided at one end of the pipeline, and a connecting groove is provided on the blocking portion, and the connecting groove is used to connect to the next pipeline;

[0009] The blocking portion is provided with a movable valve for blocking the communication groove, and the movable valve includes a telescopic crossbar, and the telescopic crossbar is provided with a blocking piece corresponding to the communication groove, and the telescopic crossbar is also provided with a blocking plate corresponding to the water injection port;

[0010] A sealing hose is provided between two adjacent pipelines, the sealing hose is communicated with the rain drain pipe, and a telescopic tube is provided on the sealing hose, and the telescopic tube is used to extend after rainwater enters the inside thereof to push the movable valve to move horizontally;

[0011] The baffle plate and the water injection port are staggered to allow rainwater inside the rainwater discharge pipe to enter the liquid injection tank and, as the water pressure continues to increase, push the one-way plugging piece to be discharged from the connecting hole to flush the sewage discharge pipe;

[0012] When the water pressure inside the rain drain pipe further increases until the telescopic tube pushes the movable valve to move horizontally, the baffle plate blocks the water inlet, and the blocking plate is misaligned with the connecting groove, opening the connecting groove to allow rainwater to enter the next pipe for step-by-step flushing.

[0013] Furthermore, the one-way blocking piece is hingedly arranged in the connecting hole, and a reset torsion spring corresponding to the one-way blocking piece is arranged in the connecting hole.

[0014] Furthermore, both ends of the pipeline are provided with placement grooves corresponding to the sealing hose;

[0015] The sealing hose is a flexible hose with telescopic function;

[0016] After rainwater in the rain drain pipe enters the sealing hose, the sealing hose expands to block the connection between the two groups of pipelines.

[0017] Furthermore, a sliding block is also provided on the telescopic crossbar;

[0018] The movable valve also includes a resisting spring that resists the slider, and the resisting spring is used to push the blocking piece to block the connecting groove after the water pressure inside the rain drain pipe is reduced.

[0019] Furthermore, the movable valve is slidably arranged on the blocking portion.

[0020] Furthermore, the telescopic tube is a corrugated telescopic tube, a guide groove opposite to the telescopic tube is opened in the accommodating groove, the telescopic tube is in contact with the telescopic cross bar, and the guide groove is used to guide the telescopic tube to extend and push the movable valve to translate.

[0021] Furthermore, the rainwater drain pipe is connected to the filtering device and the pressurizing device to input the treated rainwater into the rainwater drain pipe.

[0022] Furthermore, the two groups of pipelines are connected by a locking structure.

[0023] Furthermore, the telescopic tube is arranged at one end away from the inlet of the sealing hose, and the sealing hose is arranged in a ring shape in the placement groove.

[0024] The beneficial effects of the present invention are embodied in:

[0025] According to the present invention, in heavy rainfall weather, the one-way plugging piece can be pushed open by the water pressure inside the rain drain pipe, and the rainwater can be guided to be discharged from the connecting hole by the water pressure, thereby flushing the bottom wall of the sewage pipe to clean the sediment accumulated in the sewage pipe. A sealing hose and a movable valve are also provided. During the flushing process inside the current pipeline, the movable valve closes and blocks the rain drain pipe, and the rainwater inside the rain drain pipe cannot enter the rain drain pipe of the next pipeline until the rainwater enters the sealing hose and the telescopic tube is filled with rainwater to push the movable valve to move horizontally, thereby opening the connecting groove to allow the rainwater to enter the next pipeline. The above-mentioned arrangement is to avoid the rain drain pipes inside each pipeline from flushing the sewage pipe at the same time, thereby causing a large amount of sediment flowing in the pipeline and causing secondary blockage.

[0039] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0040] See also Figure 1-8 The present invention discloses a sewage drainage pipeline, comprising:

[0041] A plurality of pipelines 1 are sequentially spliced ​​together, wherein a partition 2 is horizontally arranged inside the pipeline 1, and the partition 2 separates the pipeline 1 into a sewage pipe 11 at the top and a rainwater pipe 12 at the bottom;

[0042] The partition plate 2 is provided with a plurality of connecting holes 21, and a one-way plugging piece 22 is provided in each of the connecting holes 21. A liquid injection groove 23 corresponding to the connecting hole 21 is provided in the partition plate 2. A water injection port 24 for connecting the liquid injection groove 23 with the rainwater discharge pipe 12 is also provided on the partition plate 2, so that rainwater in the rainwater discharge pipe 12 enters the sewage discharge pipe 11 and washes the sediment at the bottom of the sewage discharge pipe 11.

[0043] One end of the pipeline 1 is provided with a blocking portion 13 for blocking the rainwater discharge pipe 12, and a connecting groove 131 is opened on the blocking portion 13, and the connecting groove 131 is used to connect to the next pipeline 1;

[0044] The blocking portion 13 is provided with a movable valve 3 for blocking the communication groove 131, and the movable valve 3 includes a telescopic cross bar 31, and the telescopic cross bar 31 is provided with a blocking piece 32 corresponding to the communication groove 131, and the telescopic cross bar 31 is also provided with a blocking plate 35 corresponding to the water injection port 24;

[0045] A sealing hose 4 is provided between two adjacent pipelines 1, the sealing hose 4 is communicated with the rain drain pipe 12, and a telescopic tube 41 is provided on the sealing hose 4, and the telescopic tube 41 is used to extend after rainwater enters the inside thereof to push the movable valve 3 to translate;

[0046] The blocking plate 35 is staggered with the water injection port 24 to allow rainwater inside the rainwater discharge pipe 12 to enter the liquid injection tank 23 and, as the water pressure continues to increase, push the one-way plugging piece 22 to be discharged from the inside of the connecting hole 21 to flush the sewage discharge pipe 11;

[0047] The water pressure inside the rainwater discharge pipe 12 further increases until the telescopic tube 41 pushes the movable valve 3 to move horizontally, the blocking plate 35 blocks the water inlet 24, and the blocking plate 32 is misaligned with the connecting groove 131, and the connecting groove 131 is opened to allow rainwater to enter the next pipeline 1 for step-by-step flushing.

[0048] It should be noted that the water flow direction in pipeline 1 is as follows: Figure 2 As shown, the fluid flows from the inlet end of the pipeline 1 to the end having the movable valve 3 .

[0049] The present application adopts the above-mentioned structural setting, after the sewage pipe 11 and the rainwater pipe 12 are arranged in parallel, the sediment inside the sewage pipe 11 is washed away by water pressure during heavy rainfall, thereby achieving the purpose of unblocking the sewage pipe 11;

[0050] Specifically, in rainy weather, Figure 7 As shown, rainwater inside the rainwater discharge pipe 12 can enter the liquid injection tank 23 through the water injection port 24, and then when the water pressure inside the liquid injection tank 23 rises to the point where the one-way plugging piece 22 can be pushed open, the one-way plugging piece 22 opens, and rainwater is discharged from the connecting hole 21, thereby flushing the bottom wall of the sewage discharge pipe 11 to clean the sediment accumulated in the sewage discharge pipe 11;

[0051] In order to achieve the purpose of step-by-step flushing, a sealing hose 4 and a movable valve 3 are provided. The movable valve 3 is provided with a blocking plate 35 for blocking the water injection port 24 and a blocking plate 32 for blocking the connecting groove 131. During the flushing process inside the current pipeline 1, the movable valve 3 is closed to block the rainwater discharge pipe 12, and the rainwater inside the rainwater discharge pipe 12 cannot enter the rainwater discharge pipe 12 of the next pipeline 1 until the rainwater pressure continues to rise and enters the sealing hose 4 and the rainwater fills the telescopic tube 41 to push the movable valve 3 to move horizontally, thereby opening the connecting groove 131 to allow the rainwater to enter the next pipeline 1. At the same time, the blocking plate 35 closes the water injection port 24 to ensure the water pressure in the subsequent pipeline 1. Figure 8 As shown, the above arrangement is to prevent the rainwater pipes 12 inside each pipeline 1 from flushing the sewage pipe 11 at the same time, thereby causing a large amount of sediment flowing in the pipeline and causing secondary blockage.

[0052] It should be noted that the one-way plug 22 is hingedly arranged in the connecting hole 21, and a reset torsion spring corresponding to the one-way plug 22 is arranged in the connecting hole 21. The above structure is to set a one-way valve, which only allows rainwater to enter the sewage pipe 11 from the rain pipe 12. When the water pressure disappears, the one-way plug 22 closes to separate the rain pipe 12 and the sewage pipe 11 again.

[0053] It is easy to imagine that both ends of the pipeline 1 are provided with placement grooves corresponding to the sealing hose 4;

[0054] The sealing hose 4 is a flexible hose with telescopic function;

[0055] After the rainwater inside the rain drain pipe 12 enters the sealing hose 4 , the sealing hose 4 expands to block the connection between the two groups of pipelines 1 .

[0056] Through the above-mentioned structural setting, in order to avoid excessive water pressure inside the pipeline 1, which may cause leakage at the connection of the pipeline 1, a sealing hose 4 is provided. After rainwater enters the sealing hose 4 and causes it to swell, it can block the connection between the two groups of pipelines 1 to seal and avoid leakage.

[0057] In the present application, a slider 33 is also provided on the telescopic crossbar 31;

[0058] The movable valve 3 further includes a resisting spring 34 resisting against the slider 33 , and the resisting spring 34 is used to push the blocking piece 32 to block the communicating groove 131 after the water pressure inside the rain discharge pipe 12 is reduced.

[0059] It should be further explained that the movable valve 3 is slidably disposed on the blocking portion 13 , and a sliding groove corresponding to the movable valve 3 is provided in the blocking portion 13 .

[0060] It is easy to imagine that the telescopic tube 41 is a corrugated telescopic tube, and a guide groove opposite to the telescopic tube 41 is opened in the accommodating groove. The telescopic tube 41 contacts the telescopic cross bar 31, and the guide groove is used to guide the telescopic tube 41 to extend and push the movable valve 3 to translate.

[0061] It should be added that the elastic force of the resisting spring 34 is greater than or equal to the elastic force of the reset torsion spring. The above arrangement achieves the purpose of first opening the one-way plug 22 for flushing and then opening the next pipeline 1.

[0062] In the present application, it should also be noted that when the rainwater pressure is insufficient, the rainwater drain pipe 12 can be connected to the filtering equipment and the pressurizing equipment to input the treated rainwater into the rainwater drain pipe 12 to achieve the purpose of flushing the sewage pipe 11.

[0063] It should be noted that the two groups of pipelines 1 are connected via a locking structure.

[0064] It is easy to imagine that the telescopic tube 41 is arranged at one end away from the entrance of the sealing hose 4, and the sealing hose 4 is arranged in a ring shape in the mounting groove. Through the above-mentioned structural arrangement, the path for rainwater to enter the telescopic tube 41 is lengthened, so that when the elastic force of the resistance spring 34 is equal to the elastic force of the return torsion spring, the one-way plug 22 is first opened for flushing, and then the rainwater enters the telescopic tube 41 along the sealing hose 4 to trigger the movable valve 3.

[0065] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0066] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0067] In addition, "plurality" means two or more.

[0068] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
