The leaked water is collected through the water collection tank 20, so that the two electrodes 30 in the water collection tank 20 are connected through the collected water. After the processor module 50 detects that the two electrodes 30 are connected, an alarm message is sent to the outside through the wireless communication module 60, so that the leakage point can be found in time.

[0031] Preferably, the processor module 50 uses a STM32F091RC single chip microcomputer.

[0032] Preferably, the wireless communication module 60 adopts an ESP8266WiFi module.

[0033] When in use, install the alarm device on the lower side of the welding point where water leakage needs to be monitored.

[0034] See also Figure 1 In order to expand the detection range of the weld, a water guide groove 21 which is wide at the top and narrow at the bottom is provided at the upper end of the water collecting groove 20 , and the water guide groove 21 is connected to the water collecting groove 20 .

[0035] Of course, further, an inclined water guide groove may be bonded below the weld of the buoyancy tank side wall, and the lower end of the water guide groove is located on the water guide groove 21, so that the monitoring range will be wider.

[0036] See also Figure 3 , 4 A battery 40 is also installed in the equipment cavity 13, and the battery 40 is electrically connected to the processor module 50 for power supply, so that the installation of the alarm device is not restricted by wires and the installation is more convenient.

[0037] Furthermore, an antenna 61 is installed on the housing 10 , and the antenna 61 is electrically connected to the wireless communication module 60 to improve the communication effect of the wireless communication module 60 .

[0038] Furthermore, a magnet 70 is installed on one side of the equipment cavity 13 corresponding to the installation wall 14, so that the alarm device can be conveniently attached to the side wall of the buoyancy tank during installation. In this embodiment, two magnets are installed.

[0039] When in use, after the installation wall 14 is coated with sealant, the alarm device can be directly attached to the side wall of the buoyancy tank through the magnet 70, which is convenient to use.

[0040] In one embodiment, see Figure 1 A sealing strip 11 is provided on the mounting wall 14. The sealing strip 11 is elastic, and the sealing strip 11 surrounds the outside of the water collecting tank 20 and the water guiding tank 21, and the sealing strip 11 is abutted against the side wall of the buoyancy tank to achieve sealing.

[0042] See also Figure 2 The housing 10 is provided with a cover plate 15 on one side of the device cavity 13 to seal the battery 40 , the processor module 50 and the wireless communication module 60 .

[0043] The cover plate 15 may be mounted on the housing 10 by means of bolts or by means of snap fastenings.

[0044] The working principle or action process of the utility model is as follows:

[0045] When in use, the alarm device is installed on the lower side of the weld joint where the leakage needs to be monitored. If the detection range needs to be extended, an inclined water guide groove can also be bonded below the weld of the side wall of the buoyancy tank, and the lower end of the water guide groove is located above the water guide groove 21. The leaking water enters the water collection tank 20 through the water guide groove 21. As the water level rises, the water in the water collection tank 20 contacts the two electrodes 30 at the same time, so that the two electrodes 30 in the water collection tank 20 are connected through the collected water. The processor module 50 uses the single-chip microcomputer STM32F091RC as a micro control unit. The STM32F091RC provides two zero-crossing comparators COMP1 and COMP2 internally, sharing the same current bias. The alarm is arranged in the area that needs to be monitored, which can be a fixed area or multiple areas can be monitored simultaneously. T1 and T2 are two probes of the detection circuit, which are respectively connected to the input ends of the two internal comparators of the microcontroller unit (MCU). When T1 and T2 are not in contact with water, the input ends of the two comparators are 0, so the outputs of the two comparators are low level. When there is water between the probes, the resistance between the two is changed. In this way, by detecting the output level of the comparator, the water leakage information can be known.

[0046] The wireless communication module 60 uses the ESP8266WiFi module, which integrates the RF front end, memory and microcontroller on a single chip. It has extremely high receiving sensitivity and anti-interference performance, and only requires a few external components to meet the needs of wireless networks. When there is no task to be executed, the wireless communication module can be controlled to enter a dormant state. The processor module and the wireless communication module communicate data through an asynchronous serial communication interface.

[0047] The wireless communication module 60 uploads the water leakage information to the server, processes and analyzes the received information on the server, and then sends it to the PC to remind the staff to deal with the water leakage in time. When no water leakage signal is detected, the detection system does not work and enters a dormant state.
