Water pipe leakage alarm device

This creation relates to an alarm device, and more particularly to a water leakage alarm device that detects a leak in a water pipe and issues 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.

In view of this, the main purpose of this creation is to provide a water leakage warning device. By periodically detecting the water consumption, when the leakage water exceeds the set value, an alarm will be issued to indicate the water leakage condition, and the user cannot find the water leakage in time, resulting in loss of money and The issue of water resources.

The main technical means adopted to achieve the aforementioned creative purpose is that the water leakage alarm device comprises: a flow detector connected to a water pipe for obtaining water consumption through the water pipe; The module is connected to the flow detector to obtain the value of the water consumption. The control module includes one or more detection section times, a plurality of trigger times, and one or more leaking water limits. The control module is selected. The detection period time compares 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 of the control module and trigger Time and leakage limit; a buzzer that is electrically connected to the control module, and the buzzer receives an alarm from the control module.

The advantage of the creation is that the water leakage alarm device composed of the foregoing components is used to set the detection section time and the leakage limit of the control module through the setting unit during the night or when the water is not used, and the control module is in the detection section. The water consumption value of the flow detector is continuously obtained according to the selected trigger time and compared with the set leakage water limit. If the water leakage limit exceeds the set, the water leakage is detected, and the buzzer immediately issues an alarm to remind the pipeline to occur. The water leakage situation solves the problem that the existing users cannot find the pipeline leaking in time, resulting in loss of money and water resources.

For a preferred embodiment of the present invention, as shown in FIG. 1 and FIG. 2, a water pipe leakage alarm device 10 is installed on the water pipe line between the water source and the user, and the water pipe leakage alarm device 10 is used for detecting Whether there is water leakage in the water pipe.

The control module 13 includes one or more detection zone times, one or more leakage limits and a majority. a triggering time, the triggering time is less than the detecting section time, the setting unit 12 is configured to set the detecting section time, the triggering time and the leaking water limit, and the control module 13 triggers each segment according to the selected detecting section time. Obtaining and comparing the water consumption amount and the water leakage limit value, and determining that the water consumption amount of the triggering time exceeds the set water leakage limit value, that is, an alarm is issued by the buzzer 14 or the display unit 15; in this embodiment, The detection period time 131 is a self-definable or time value built in the control module 13, such as: 1 hour, 2 hours, 4 hours or 8 hours, and the leakage water limit 132 is self-definable or The fixed water quantity value, for example, 0.5 liter, 1 liter, the trigger time is a self-setting or the time value built in the control module 13, for example, 10 minutes, 30 minutes, the user sets the control mode through the setting unit 12 respectively. The detection section time, the triggering time and the leakage water limit of the group 13 are, for example, setting the detection section time to 4 hours, the triggering time to 30 minutes, and the leakage water limit to 0.5 liter, that is, the control module 13 is 4 hours. The water consumption in the time period is obtained every 30 minutes, and it is judged that the water consumption in the time period exceeds 0.5 liter, and an alarm of water leakage is issued.

Referring to FIG. 3, a cross-sectional view of the flow detector 11 in the preferred embodiment includes a blade 111, a rotating shaft 112 disposed on the axis of the blade 111, and a rotating shaft 112. a turntable 113 at the end, a bump 114 formed on the turntable 113, and a pair of micro switches 115 disposed on the bump 114, the bump 114 being located on the turntable 113 and different from the end of the blade 111, when the blade 111 When rotated by the water flow, the rotary disk 113 is synchronously rotated by the rotating shaft 112. Each time the bump 114 on the rotary disk 113 rotates, the micro switch 115 is triggered once, and the corresponding water consumption value is output; wherein the rotary disk 113 and the fine movement The switch 115 can be replaced by a rotary encoder, or the bump 114 on the turntable 113 can be changed to a magnet bump, so that a Hall sensor can detect its magnetic field signal and output a corresponding water consumption value.

Referring to FIG. 4 , it is a water leakage detection flowchart of the control module 13 , and the setting unit 12 sets a repeated detection section time and a water leakage limit (101), and the control module 13 respectively counts the detection section time. And the triggering time (102), the control module 13 counts the arrival triggering time (103), determines whether the water consumption is greater than the leakage water limit (104), and if the leakage water limit exceeds the leakage water (105), if the counting reaches the detection section At time (106), the buzzer 14 sends an alarm of water leakage (107). If the counting period does not reach the detection period, the triggering time continues to determine whether the water leakage exceeds the leakage limit, and if the control module 13 is in the step ( 103) Judging that the water leakage amount does not exceed the leakage water limit value indicates that there is no water leakage (108), the counting trigger time and the current detection period time (109) are stopped, and the next detection section time (110) is waited for re-detection.
