Water pipe leakage alarm device and leak detection method thereof

The invention relates to a water leakage alarm device, in particular to a water pipe leakage alarm device capable of detecting water leakage and issuing an alarm.

There are water towers in the building and the house to connect the tap water required by each user. However, there is no feasible leak detection device in all the pipelines. The existing tap water pipelines are mostly located in the pipes or walls of the building, and the materials are mostly used. The rigid plastic pipe, together with the joints, is bonded by an adhesive. When the tap water pipe is subjected to external force or earthquake shaking and rubbing against the building, it is easy to cause cracks in the pipe wall or its joints, resulting in water leakage, general users or families. In this case, it is not easy to find water leakage. It is necessary to wait until two months later to receive a large amount of water bill, and then there will be water leakage in the home. The existing building has less than dozens of water pipes with hundreds of water pipes. At the same time, it is necessary to pay a large inspection fee for each user or household in the building to check the state of the water pipe in the home, and it is impossible to immediately know whether the pipeline of each user leaks water, and it is easy to cause loss of money and water resources due to water leakage, so how to Know the leaks as soon as possible, and solve or repair the water leakage problem early to avoid losing money and valuable water resources. solved problem.

As mentioned above, the existing water pipes of existing buildings are mostly located in pipes or walls, and users will have to wait until they receive a large water bill to find out that they have In the case of water leakage, the problem of loss of a large amount of money and water resources is caused. Therefore, the main purpose of the present invention is to provide a water leakage warning device and a water leakage detecting method for detecting water consumption through timing, and when the leakage water amount exceeds a set value, An alarm is issued to indicate the water leakage condition, which solves the problem that the user cannot find the water leakage in time, resulting in loss of money and water resources.

The main technical means adopted to achieve the foregoing objectives is that the water leakage detecting method includes: setting a detecting section time and a leaking water limit; detecting a leak amount every other triggering time in the detecting section time; determining the trigger Whether the amount of water leakage exceeds the limit of leakage water in the time limit; the limit value exceeding the leakage water indicates that an alarm needs to be issued when the water leakage occurs, and the water leakage limit value indicates that there is no water leakage, and the water leakage amount is repeatedly detected according to the time of the detection section.

The main technical means adopted to achieve the foregoing objective is that the water leakage alarm device comprises: a flow detector connected to a water pipe for obtaining water consumption through the water pipe; a control module The control module is connected to the flow detector to obtain the value of the water consumption. The control module includes one or more detection zone times, a plurality of trigger times, and one or more leakage water limit values. The control module is selected. The detection time is compared with the water consumption value and the leakage water limit according to the set trigger time; a setting unit is electrically connected with the control module, and the setting unit is used to set the detection section time and the trigger time of the control module. And a leaking water limit; a buzzer electrically connected to the control module, the buzzer being controlled The signal of the module sounds an alarm.

The water leakage warning device composed of the foregoing components is used to set the detection section time and the leakage water limit of the control module through the setting unit during the nighttime or when the water is not used, and the control module selects the trigger according to the selected section time. The time continues to obtain the water consumption value of the flow detector and is compared with the set leakage water limit. If the water leakage limit exceeds the set value, the water leakage occurs, and the buzzer immediately issues an alarm to remind the pipeline of the water leakage and solve the existing user. It is impossible to find the leaking of the pipeline in time, resulting in the loss of money and waste of water resources.

The segment time, the trigger time and the water leakage limit, the control module 13 obtains and compares the water consumption and the water leakage limit according to each trigger time in the selected detection period time, and determines that the water consumption of the trigger time exceeds the set value. The leaking water limit is issued by the buzzer 14 or the display unit 15; in this embodiment, the detecting section time 131 is a self-setting or time value built in the control module 13, such as: Hours, 2 hours, 4 hours or 8 hours, the water leakage limit 132 is a self-setting or fixed water quantity value, such as: 0.5 liter, 1 liter, the trigger time is a self-setting or control mode The time value of the built-in group 13 is 10 minutes, 30 minutes, and the user sets the detection section time, the trigger time and the leaking water limit of the control module 13 through the setting unit 12, for example, setting the detection section time to 4 hours. The triggering time is 30 minutes, and the leakage water limit is 0.5 liters, that is, the control module 13 obtains the water consumption in the time interval every 30 minutes within 4 hours, and judges that the water consumption in the time period exceeds 0.5 liter, and the water leakage is issued.
