TECHNICAL FIELD
[0001] The utility model relates to a sewage pipeline technical field, especially a sewage pipeline with blockage early warning function. BACKGROUND
[0002] Sewage pipelines are usually used to discharge wastewater, sewage or other liquids into a sewage treatment system or a drainage system. These pipelines need to have certain corrosion resistance and sealing performance to ensure long-term stable operation. In residential, commercial buildings or industrial plants, sewage pipelines are used to discharge wastewater from various facilities such as kitchens, bathrooms, laundry rooms, etc. into a sewage treatment system or a sewer, and the U-shaped pipe is a type of water trap. The water trap plays a role in preventing gases in the sewage pipeline system from entering the room, but it is also one of the accessories that is most prone to blockage in the sewage pipeline. If larger garbage is discharged into the interior of the residential sewage pipeline, the water trap is prone to blockage. The blockage situation will become more and more serious with the accumulation of blocked garbage in the sewage pipeline, eventually leading to almost no drainage, resulting in water returning to the owner's room, causing irreparable loss. SUMMARY

[0015] Further, the U-shaped pipe is provided with an access hole at the bottom, and a plug is threadedly connected to the access hole.
[0016] The utility model discloses a beneficial effect is:
[0017] The utility model discloses a sewage pipeline with the early warning function of blockage, through setting up detection pipe and liquid level meter, can real -time monitoring the liquid level situation in sewage pipeline. When the water inlet pipe liquid level gradually rises when the residence sewage pipeline is discharged into larger garbage and leads to the trend of trap blockage, and the liquid level change signal detected by the liquid level meter is transmitted to the controller. Before the blockage develops to almost impossible drainage, causes the serious loss of indoor return water, the controller can start the audible and visual alarm according to the preset liquid level threshold value, and sends the early warning of blockage to the owner in time, reminds the owner to take the U-shaped pipe blockage, avoids the indoor return water caused by the serious blockage of pipeline, effectively reduces the property loss risk that the owner can suffer from;
[0018] The setting of the emergency sewage pipe provides an emergency drainage channel when the pipeline is blocked. When the pipeline is detected to be blocked and the liquid level reaches the warning value, the controller can control the electromagnetic valve to open, so that the sewage in the water inlet pipe flows into the drain pipe through the connecting pipe via the emergency sewage pipe, avoiding excessive accumulation of sewage in the pipeline, further ensuring the smoothness of pipeline drainage, and preventing sewage overflow caused by blockage.

[0023] The specific embodiments of the present application will be further described below with reference to the accompanying drawings. The same parts are denoted by the same reference numerals.
[0024] It should be noted that the words "front", "back", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the words "inner" and "outer" refer to the directions towards or away from the geometric center of a particular component.
[0025] In order to make the content of the present application more easily understood, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.
[0026] As shown in the drawings, Figs. 1-2 A sewage pipeline with a blockage early warning function, comprising a water inlet pipe 1, a U-shaped pipe 2, a drain pipe 3, a detection pipe 4, an emergency sewage pipe 5, a connecting pipe 6, and a warning device.
[0027] The warning device comprises a liquid level meter 8, a controller 9, and an audible and visual alarm 10.
[0028] The water inlet pipe 1 is in communication with one end of the U-shaped pipe 2, and sewage flows into the U-shaped pipe 2 through the water inlet pipe 1; the drain pipe 3 is connected to the other end of the U-shaped pipe 2 away from the water inlet pipe 1, the connecting pipe 6, the U-shaped pipe 2, and the drain pipe 3 are communicated through a tee joint, and are used for discharging sewage.
[0029] The detection pipe 4 is in communication with the water inlet pipe 1, and the end thereof away from the water inlet pipe 1 is inclined upward, which prevents sewage from entering the detection pipe 4 and ensures that the liquid level in the detection pipe 4 can accurately reflect the liquid level in the water inlet pipe 1 when the pipeline is blocked.
[0030] The liquid level meter 8 is installed on the detection pipe 4, and the model of the liquid level meter 8 selected in the present embodiment is MY-136. When the pipeline is blocked, sewage enters the detection pipe, and the liquid level meter 8 can measure the change in the liquid level in the detection pipe 4 and transmit the liquid level data to the controller 9 in real time.
[0031] The controller 9 is a controller with PLC as the core, and specifically can adopt a Mitsubishi PLC controller FX3U-16MT / ES-A and a Siemens S7-200 SMART series controller.
[0032] One end of the emergency sewage pipe 5 is in communication with the water inlet pipe 1, and the other end is inclined upward, which also plays a role in preventing sewage from flowing backward. The connecting pipe 6 is in communication with the drain pipe 3, and an electromagnetic valve 11 is arranged between the emergency sewage pipe 5 and the connecting pipe 6. The electromagnetic valve 11 is in a normally closed state, which prevents the sewage pipeline from emitting a bad smell.
[0033] When the controller 9 receives the clogging early warning signal sent by the liquid level meter 8, a control signal is immediately sent to the electromagnetic valve 11 to open the electromagnetic valve 11, so that the sewage in the water inlet pipe 1 can flow into the drain pipe 3 through the emergency sewage pipe 5 and the connecting pipe 6, thereby avoiding the accumulation of sewage in the pipeline to cause backwater.
[0034] In addition, the bottom of the U-shaped pipe 2 is provided with an access hole 12, and a plug 7 is threadedly connected to the access hole 12. When the inside of the U-shaped pipe 2 needs to be cleaned due to clogging, the plug 7 can be conveniently screwed off, and the U-shaped pipe 2 can be maintained and repaired.
[0035] Meanwhile, the audible and visual alarm 10 is electrically connected to the controller 9. Once the controller 9 determines that the pipeline is at risk of clogging, the audible and visual alarm 10 is triggered to send an audible and visual alarm to remind personnel to clean the pipeline in time, thereby playing a warning role.
[0036] The above merely describes the preferred embodiments of the utility model patent and is not intended to limit the utility model patent. Any modification, equivalent replacement and improvement made within the spirit and principle of the utility model patent shall be included in the protection scope of the utility model patent.
