Description

Water leakage detection device

The present invention relates to a detection device, in particular to a water leakage detection device.

The world is currently experiencing water shortage, and this water shortage problem is becoming more and more serious.

The operation principle of the water leakage detection device 100 is described in detail below: Referring to FIG. 1, when in use, water flows from the right into the water channel 63 including the water flow 64 through a water input port 61. Then, the water flows left to the water pipe 20 and the third sensor 43 provided in the water pipe 20. In addition, the turbine 30 is located on the left side of the third sensor 43, which rotates under the instruction of the stepping motor 10 and pushes the water to flow to the left. The stepping motor 10 is located on the water pipe 20 and to the left of the turbine 30. The valve 50 is arranged under the stepping motor 10. When it is detected that no water leakage has occurred, the water flows to the left from the water output port 62 out of the water pipe 20 to the outside water plant or the next equipment that needs water. In the above description, the connection between the first to third sensors 41-43 and the stepping motor 10 and the connection between the turbine 30 can be realized in a wired or wireless manner.

When the first sensor 41 and/or the second sensor 42 detects that water leakage does occur, it will send a signal to the stepping motor 10 and notify the water leakage. Then, the stepping motor 10 will send a signal to the valve 50 to close the water pipe 20 to prevent the water from continuing to flow to the left and causing water waste. At this time, the stepping motor 10 will send a signal to the turbine 30 to stop rotating, so as to stop driving the water in the water pipe 20 to flow to the left. The first sensor 41 and/or the second sensor 42 also send a signal to the first light emitting diode (LED) lamp 82 to cause it to emit light to indicate that water leakage has occurred. The first sensor 41 and / or the second sensor 42 sends a signal to the buzzer 84 further allowed to issue audio warnings to alert people near water leakage occurs.

The connection between the first/second sensor 41/42 and the stepping motor 10, the connection between the stepping motor 10 and the valve 50, the connection between the stepping motor 10 and the turbine 30 Connection can be achieved by wired or wireless.

In the above description, the first switch 85 can be pressed to restart the water leakage detection device 100; or the second switch 86 can be pressed to stop the water leakage detection device 100 for repair and maintenance. It has nothing to do with water leakage. The first LED lamp 82 is used to indicate water leakage; and the second LED lamp 83 is used to visually indicate that there is no water leakage. The LCD screen 81 receives a signal from the third sensor 43 to visually display the amount of water flowing through the water channel 63 in liters.

The following three aspects of the present invention deserve special attention:

1. In the process of detecting water leakage, the water keeps flowing in the water pipe. But the sensor will It is judged that this is normal water use, or water leakage has occurred. If after a long period of time (depending on the user's requirements and settings), the water continues to flow without interruption, the first sensor 41 and/or the second sensor 42 will automatically detect the water leakage This occurs, and a command is issued to the stepping motor 10 to close the valve 50 to stop the water leakage, and then the user is notified of the water leakage.

2. The turbine 30 is rotated by the water flowing in the water passage 63. The main task of the turbine 30 To operate the third sensor 43 for reading the amount of water used and allow the reading to be displayed on the LCD screen 81.

3. Use the LCD screen to display the amount of water flowing through the water channel 60 and show the normal flow of water move. When water leakage is detected, the water leakage detection device 100 transmits the water leakage information to the user's mobile phone via the Internet. The water leakage detection device 100 can also store information on the amount of water used during a two-year period. The device can read this information from the LCD screen 81 to know the details of the amount of water used. Therefore, the present invention can achieve the above-mentioned objects without requiring personnel to read the amount of water used, control the state of the water flow, and transmit and store information about the amount of water flow.

From the above description, it can be seen that the present invention has technical features that are not available in the conventional technology It can achieve effects that cannot be achieved by conventional technologies, meets patent requirements, and has patent value.

The above description is considered as an explanation of the principle of the present invention. In addition, since those skilled in the art will easily think of many modifications and changes, it is not desirable to limit the present invention to the exact structure and operation shown and described in the scope of the invention, so all appropriate modifications and equivalents can be adopted.
