Technical Field

[0001] The utility model relates to the technical field of backflow alarm devices, and in particular to a backflow alarm device for an Internet of Things pipeline. Background Art

[0002] Backflow is a common phenomenon in pipeline transportation. Backflow will cause the water flow direction to change, affect the normal operation of the pipeline, and even cause equipment damage and waste of resources. Therefore, timely detection and alarm of backflow is of great significance to ensure the normal operation of the pipeline.

[0003] Traditional pipeline backflow detection methods usually use manual inspections or installation of sensors, which have problems such as untimely detection and high false alarm rate. Therefore, the present invention proposes a pipeline backflow alarm device based on Internet of Things technology, which can realize real-time monitoring and remote alarm, and improve detection accuracy and efficiency.

Magnetic induction sensors are placed in the sensor mounting holes and then sealed with glue. Two rubber pad mounting holes are opened in the upper part of the semi-cylinder, and connecting rubber pads are installed in the rubber pad mounting holes.

[0010] Furthermore, in order to better realize the utility model, the shape of the rubber pad is consistent with the planar shape of the semi-cylinder, and two raised rubber pad connecting columns are provided on the top of the rubber pad. The rubber pad connecting columns are inserted into the rubber pad mounting hole. A groove is opened at the upper position of the rubber pad as a bending groove to facilitate the bending of the rubber pad. A magnet is buried in the lower position of the rubber pad. When the rubber pad fits the semi-cylinder, the position of the magnet corresponds to the sensor mounting hole.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0019] Therefore, the following detailed description of the embodiments of the utility model provided in the accompanying drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents selected embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0020] Figure 1-Figure 3This is a specific embodiment of the utility model, which is an Internet of Things pipeline backflow alarm device. The bottom of the water meter housing 1 is connected to the pipeline through a threaded pipe 101. A semi-cylinder 201 is fixedly connected to the bottom of the threaded pipe 101. A backflow detection device 2 is arranged in the semi-cylinder 201. The backflow detection device 2 detects whether there is backflow in the pipeline. The plane of the semi-cylinder 201 is perpendicular to the water flow direction in the pipeline. The backflow detection device 2 includes a rubber pad 202, which is hung and fitted on the plane of the semi-cylinder 201. Four through holes are opened in the middle and lower part of the semi-cylinder 201 as water holes 2011, and holes are opened between the water holes 2011 as sensor installation holes 2013. The magnetic induction sensor is placed in the sensor installation hole 2013 and sealed with glue. Two rubber pad installation holes 2012 are opened in the upper part of the semi-cylinder 201, and the rubber pad 202 is installed and connected in the rubber pad installation hole 2012. The shape of the rubber pad 202 is consistent with the planar shape of the semi-cylinder 201. Two raised rubber pad connecting columns 2021 are provided on the top of the rubber pad 202. The rubber pad connecting columns 2021 are inserted into the rubber pad mounting holes 2012. A groove is opened at the upper position of the rubber pad 202 as a bending groove 2022 to facilitate the bending of the rubber pad 202. A magnet 2023 is buried at the lower position of the rubber pad 202. When the rubber pad 202 fits the semi-cylinder 201, the position of the magnet 2023 corresponds to the sensor mounting hole 2013.

[0021] When a backflow occurs, water will flow through the water hole 2011 and push open the rubber pad 202. The moving rubber pad 202 will drive the magnet 2023 to move. At this time, the sensor will detect the change in magnetic force and determine that a backflow occurs.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
