Description

Technical Field

[0001] The present invention relates to the technical field of drainage, and in particular to a device and a method for using the device to prevent backflow caused by blockage in a drainage system. Background Art

[0002] In modern building drainage systems, downpipes are key components that drain rainwater and sewage from inside and outside the building through pipes. However, due to long-term use, unreasonable pipe design or untimely pipe cleaning, downpipes are often blocked. When downpipes are blocked by debris, silt and other substances, poor drainage will cause sewage to flow back. In severe cases, sewage will flow back into the room, causing the sanitary environment in the house to deteriorate, and even cause property losses and health and safety issues.

[0003] At present, in order to solve the problem of blockage in sewer pipes, the construction industry usually prevents blockage by regularly inspecting and cleaning the pipes. However, this maintenance method is not only labor-intensive, but also difficult to monitor in real time, and it is impossible to detect and deal with the problem as soon as the blockage occurs. Especially in bad weather (such as heavy rain) or when the water consumption is high, the pressure in the sewer pipe increases sharply. If blockage occurs during this period, the risk of sewage backflow is greatly increased, which brings great inconvenience and potential damage to residents and building managers. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a device and a method for using the device to prevent backflow due to blockage in a drainage system, thereby solving the problem that the existing drainage system cannot prevent blockage and the blockage situation cannot be understood in a timely manner.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a device to prevent backflow due to blockage in a drainage system, comprising a floor, a main pipe installed inside the floor, a community sewage pipe well, and a sewer pipe installed inside the floor and connected to the main pipe, an overflow pipe is installed on the outside of the main pipe, an auxiliary drainage structure is installed on the outside of the overflow pipe for draining water when the main pipe is blocked, a sensor component for detection is installed on the outside of the auxiliary drainage structure, and the water outlet ends of the main pipe and the auxiliary drainage structure are both connected to the community sewage pipe well.

[0006] Preferably, the auxiliary drainage structure comprises a branch pipe, the branch pipe is installed on the outside of the main pipe, and the top of the branch pipe is connected to the overflow pipe, and the sensor component is installed at the bottom of the vertical section of the branch pipe.

[0008] Preferably, the sensing assembly comprises a sensor, which is installed in the middle of the auxiliary drainage structure and sends out a signal when water flows through the auxiliary drainage structure.

[0009] A drainage anti-blocking system includes a sensing module, a signal processing module, an alarm module and a property management module. The sensing module is used to monitor the water flow inside an auxiliary drainage structure; the signal processing module is used to receive and process the signal transmitted by the sensing module; the alarm module is used to issue an alarm reminder after receiving the signal from the signal processing module; the property management platform module is used to provide a visual system monitoring interface for property management personnel.

[0010] Preferably, the sensing module may be one of a water flow sensor, a water immersion sensor, a water level sensor and an ultrasonic flow meter.

[0011] Preferably, a method for using a device for preventing backflow from blockage in a drainage system comprises the following steps:

[0012] S1. The main pipe is blocked, and the water flows from the overflow pipe into the auxiliary drainage structure;

[0027] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Embodiment 1:

[0029] Please see attached Figure 1 and attached Figure 3The embodiment of the present invention provides a device for preventing backflow due to blockage of a drainage system, comprising a floor 1, a main pipe 2 installed inside a building, and a sewer pipe 3 installed inside the floor 1 and connected to the main pipe 2. The bottom drainage end of the main pipe 2 is connected to a sewage pipe well 6 in a community. An overflow pipe 4 is installed outside the main pipe 2. A branch pipe 5 is installed at the open end of the overflow pipe 4. The bottom drainage end of the branch pipe 5 is connected to the sewage pipe well 6 in the community. The main pipe 2 is used for normal drainage of the building. Wastewater flows from the main pipe 2 to the inside of the sewage pipe well 6 in the community. When the main pipe 2 is blocked, the wastewater accumulates upward. When it reaches the overflow pipe 4, it flows from the overflow pipe 4 to the inside of the branch pipe 5. The wastewater is diverted through the branch pipe 5 to reduce the blockage pressure of the overflow pipe 4 and prevent it from flowing back into the room. Secondly, a sensor component is installed outside the branch pipe 5. When water flows through the branch pipe 5, a signal is sent to notify the property and relevant personnel to investigate the problem. The sensor can be one of a water flow sensor, a water immersion sensor, a water level sensor and an ultrasonic flow meter. If a water flow sensor or a water immersion sensor is used, the sensor 7 is installed inside the branch pipe 5 and directly contacts the water body. If a water level sensor or an ultrasonic sensor is used, the sensor 7 is installed outside the branch pipe 5 and detects the water flow inside the branch pipe 5 by means of capacitance, without contacting the water body, thereby reducing the risk of water leakage. Then, a signal is sent to the property management platform to reflect the sewage discharge situation.

The device for preventing backflow due to blockage in drainage is applied to a multi-story building, and includes a floor 1, a main pipe 2 installed inside the building, and a vent pipe 8 arranged in parallel to the edge of the main pipe 2. The vent pipe 8 and the main pipe 2 are connected through an overflow pipe 4. A plurality of overflow pipes 4 are evenly distributed in the bathroom of the high-rise building. When the main pipe 2 of the current floor is blocked, waste water accumulates and then enters the branch pipe 5 of the current floor from the overflow pipe 4, and then triggers the sensor 7, thereby sending a signal to notify the property management personnel to conduct investigation, maintenance, and repair.

[0032] In this embodiment, the floors where the drainage system is blocked can be quickly understood, and maintenance and response can be carried out in a timely manner to improve maintenance efficiency. At the same time, the ventilation pipe 8 can prevent odor from returning to the residents' homes.
