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 ultrasonic detection 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 ultrasonic detection. Utility Model Content

[0019] A maximum value A and a minimum value B are set in the detection processing device;

[0020] When the detected ultrasonic frequency or speed is at a constant value A and is stable, it can be determined that the drainage riser is in an empty pipe state;

[0039] This embodiment discloses a drainage pipe blockage alarm device based on the ultrasonic detection principle, wherein the alarm device 2 comprises:

[0040] An ultrasonic detector 201, which is disposed at a straight pipe section 101 at the bottom of a building drainage riser 1; and

[0041] A detection and processing device 202 connected to the ultrasonic detector 201 and disposed outside the straight pipe section 101, the detection and processing device 202 is used to detect in real time the change in the frequency or speed of the ultrasonic wave generated by the ultrasonic detector 201;

[0042] The alarm device 2 determines the blockage condition of the drainage riser 1 by detecting the change in the frequency or speed of the ultrasonic wave generated by the ultrasonic detector 201 .

[0043] 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 two parts, namely, an ultrasonic detector 201 and a detection processing device 202, on one side of the building drainage riser 1. The alarm device 2 of this embodiment mainly detects the blockage of the drainage riser 1 based on the ultrasonic detection principle. Therefore, the ultrasonic detector 201 is fixed to the outside of the straight pipe section 101 of the drainage riser 1 or integrated into the straight pipe section 101 of the drainage riser 1 in an integrated manner. The ultrasonic detection principle is used in combination with the detection processing device to detect the change of the ultrasonic frequency or speed emitted by the ultrasonic detector 201 in real time, so as to judge the blockage of the drainage riser 1.

[0044] 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;

[0045] All detection and processing devices 202 are connected to the signal processing weak current box 3, and the signal processing weak current box 3 processes the ultrasonic frequency or speed change signal generated by the ultrasonic detector 201 detected by the detection and processing device 202;

[0046] The signal processing weak current box 3 communicates with the terminal device 5 via wired and / or wireless means.

[0047] 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.

[0048] The terminal device 5 of this embodiment includes a signal receiving processor 4; and a control room computer and / or an indoor video intercom screen and / or an owner's mobile phone; wherein the control room computer, the indoor video intercom screen, and the owner's mobile phone are all provided with alarms.

[0049] As the main design point of the present application, the alarm device 2 of the present embodiment mainly detects the change of the ultrasonic frequency or speed generated by the ultrasonic detector 201 detected by the detection processing device 202 as follows:

[0050] A constant value A and a constant value B are set in the detection processing device 202;

[0051] When the detected ultrasonic frequency or speed is at a constant value A and is stable, it can be determined that the drainage riser 1 is in an empty pipe state;

[0052] When the detected ultrasonic frequency or speed 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 1 is in a blocked state;

[0053] When the detected ultrasonic frequency or speed is between the constant value A and the constant value B, and the fluctuation is unstable, it can be determined that the drainage riser 1 is in a drainage state.

[0054] When the ultrasonic detection principle is applied to the drainage riser 1, the present embodiment uses the real-time detected ultrasonic frequency or speed change 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 set in the detection processing device according to the actual situation, 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 result is transmitted to the terminal device 5 in real time by the detection processing device 202.

[0055] Specifically, the ultrasonic detector 201 is used to generate scattered waves by emitting ultrasonic waves of a certain frequency or speed to bubbles and solid particles in the flowing liquid through the generating transducer according to the Doppler effect, and the scattered waves are received by the receiving transducer r, and the frequency or speed change is proportional to the moving speed of the particles (or bubbles). Therefore, the three states of the drainage riser 1 can be obtained according to the detected ultrasonic frequency or speed change, namely, the empty pipe state, the drainage state, and the blocked state.

[0056] 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;

[0057] 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.

[0058] Preferably, the power supply mode of the alarm device 2 of this embodiment is:

[0059] Plug into a 220V socket via a power adapter; or

[0060] Configure the battery.

[0061] In order to reduce the use cost, the battery of this embodiment can be a rechargeable dry cell or other types of rechargeable batteries.

[0062] In the above technical solution, the utility model provides a drainage pipe blockage alarm device based on the ultrasonic detection principle, which has the following beneficial effects:

[0063] The alarm device 2 of the utility model utilizes the ultrasonic detection principle to monitor the blockage condition of the building drainage riser 1 in real time according to the changes in the internal medium flow state, and can realize accurate and timely signal feedback and alarm. It has a novel structure and meets the monitoring and use requirements of the blockage condition of the building drainage riser 1.
