Description

Technical Field

[0001] The utility model relates to the technical field of building drainage pipelines, in particular to a drainage pipeline blockage alarm device based on the electromagnetic induction principle. Background Art

[0002] The building drainage is discharged from the toilet or kitchen on each floor through the drainage riser. The pipes are discharged to the outside on the underground floor. Pipe blockage often occurs in the horizontal section of the discharge pipe. Once blocked, there is a risk that sewage will flow back into the room from the sanitary ware and floor drains of the residents on the ground floor, polluting the indoor environment, damaging the residents' decoration, and causing extreme sensory discomfort to the residents, which is actually a major accident for the residents.

[0003] Drainage risers are relatively complex. For multi-story projects, such as six floors, during peak hours in the morning and evening, the water flow at the bottom of the drainage risers is relatively simple, and the pipes are not fully flowed for a long time, making it easy to determine whether the pipes are blocked. For high-rise buildings, since the drainage risers are responsible for draining more layers, during peak hours in the morning and evening, the water flow at the bottom of the risers is complex, and the pipes are close to being fully flowed for a long time, with large fluctuations. Retrieving existing pipeline blockage detection technologies is prone to false alarms, increasing the workload of the property, and since there are many drainage risers in the households, it is impossible to detect which household's drainage riser is blocked. Therefore, how to monitor the building drainage risers in real time has become an urgent problem to be solved in this field.

[0004] Therefore, based on the above technical problems, technicians in this field urgently need to develop a drainage pipe blockage alarm device based on the principle of electromagnetic induction. Utility Model Content

It has a novel structure and meets the monitoring and use requirements of the building's drainage riser blockage.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] The utility model discloses a drainage pipe blockage alarm device based on the electromagnetic induction principle, the alarm device comprising:

[0019] Furthermore, the change of the magnetic field of the induction coil detected by the detection device is:

[0020] A constant value A is set in the detection device (the initial value set when the pipeline is empty);

[0021] When the detected magnetic flux is at a constant value A and is stable, it can be determined that the drainage riser is in an empty pipe state;

[0022] When the detected magnetic flux is at a constant value B and remains constant for more than a certain period of time C, it can be determined that the drainage riser is in a blocked state;

[0023] When the detected magnetic flux is between the constant value A and the constant value B, and the fluctuation is unstable, it can be determined that the drainage riser is in a drainage state.

[0024] Furthermore, when the straight pipe section of the drainage riser meets the wiring requirements, the signal processing weak current box communicates with the terminal device via 485, 232 or CAN wired mode;

[0040] This embodiment discloses a drainage pipe blockage alarm device based on the principle of electromagnetic induction. The alarm device 2 includes:

[0041] A real-time monitoring component, which is arranged at a straight pipe section 101 at the bottom of a building drainage riser 1, and has an induction coil 201 wound around the straight pipe section 101;

[0042] A detection device 202 connected to the induction coil 201 and disposed outside the straight pipe section 101, the detection device 202 is used to detect the change of the magnetic field generated by the induction coil 201 in real time; and

[0043] A transmission module 203 that communicates with the detection device 202 and transmits the magnetic field change signal detected by the detection device 202 to the terminal device 5;

[0044] The alarm device 2 determines the blockage condition of the drainage riser 1 through the change of the magnetic field of the induction coil 201 .

[0045] Specifically, this embodiment discloses an alarm device 2 capable of real-time monitoring whether a building drainage riser 1 is blocked; the alarm device 2 is mainly provided with three parts, namely, a real-time monitoring component, a detection device 202 and a transmission module 203, on the side of the building drainage riser 1. Among them, the alarm device 2 of this embodiment mainly detects the blockage of the drainage riser 1 based on the principle of electromagnetic induction. Therefore, the real-time alarm component uses an induction coil 201 wound around the drainage riser 1, and uses the charged ions containing paramagnetic substances in water to affect the changes of the external electromagnetic field through the magnetic medium, and calculates the magnetic flux by detecting the changes in the strength of the magnetic field and amplifying the signal.

[0046] The alarm device 2 of this embodiment needs to be set according to the number of drainage risers 1 of the building, specifically: each straight pipe section 101 of the drainage riser 1 of the building is provided with a set of alarm devices 2;

[0049] When in use, the alarm device 2 of this embodiment is arranged on each drainage riser 1 of the building, and in actual design, the pipeline and the alarm device 2 can be taken as a whole to form an independent product, for example, the alarm device 2 is integrated into the pipeline, and the pipeline is connected with the upper and lower pipelines through the connection parts such as the pipe joint, and finally forms a complete drainage riser 1. The alarm device 2 can also be directly fixed on the existing drainage riser 1 by using the fasteners such as the clamp.

[0056] When the present embodiment is applied to the drainage riser 1 based on the principle of the influence of magnetic medium on the external magnetic field, the paramagnetism of charged ions in the water flow is used to affect the change of the magnetic field of the magnetic induction coil 201 to judge the condition of the drainage riser 1, which is specifically divided into the above three conditions. The setting of the above values ​​can be based on the actual situation, and the corresponding values ​​can be set in the detection device 202, and then the working condition of the drainage riser 1 can be judged according to the change of the detection value, and finally the detection structure is transmitted to the terminal device 5 in real time using the transmission module 203.

[0057] Preferably, when the straight pipe section 101 of the drainage riser 1 of this embodiment meets the wiring requirements, the signal processing weak current box 3 communicates with the terminal device 5 via a wired method of 485, 232 or CAN;

[0058] When the straight pipe section 101 of the drainage riser 1 does not meet the wiring requirements, the signal processing weak current box 3 communicates with the terminal device 5 in a wireless manner via Zigbee, WiFi or Bluetooth.

[0059] Preferably, the power supply mode of the alarm device 2 of this embodiment is:

[0060] Plug into a 220V socket via a power adapter; or

[0061] Configure the battery.

[0062] In order to reduce the use cost, the battery of this embodiment can be a rechargeable dry cell or other types of rechargeable batteries.

[0063] In the above technical solution, the utility model provides a drainage pipe blockage alarm device based on the electromagnetic induction principle, which has the following beneficial effects:

It has a novel structure and meets the monitoring and use requirements of the blockage situation of the building drainage riser 1.
