Technical Field

[0001] The present invention relates to the technical field of voltage detection, and in particular to a water area voltage detection device and a detection method. Background Art

[0002] At present, swimming pools, sightseeing pools and large fish ponds are often equipped with various electrical equipment, such as water pumps, wall lamps, underwater lights and oxygen pump lines. When the lines laid in the water are aged and damaged, or when there are problems with the electrical equipment, it is easy to cause leakage. If the installation of the swimming pool power supply equipment does not follow the safety regulations or regular inspections are not carried out, the risk of electric shock is very high.

[0003] In addition, illegal electric fishing activities still exist in some fish ponds or waters, which is a "chronic disease" that endangers the construction of water ecological civilization. If supervision is not effective, it will have a serious impact on fishery resources and the ecological environment of fishery waters.

[0004] Therefore, how to provide a device and a detection method that can detect the voltage in water areas around the clock is an urgent problem that those skilled in the art need to solve. Summary of the invention

[0005] In view of this, the present invention has a simple structure and is convenient to be directly set up within the water area, and can realize all-weather voltage detection. The layout of probes is used to realize the detection of voltage direction, which is conducive to further determining the specific location of the leakage point or discharge point.

[0006] In order to achieve the above object, the present invention adopts the following technical solution:

[0020] V OX ,V OY ,V OZ Perform vector addition to obtain the vector voltage V S =V OX +V OY +V OZ , determine voltage detection information, including: the voltage direction of the vector voltage.

[0021] Preferably, the method further includes the step of sending the voltage detection information: when it is detected that the absolute value of the potential difference between any two probes is higher than a set threshold, the water area voltage detection device enters a high-performance mode from a sleep mode, and executes the step of wirelessly sending the voltage detection information to an external computer.

After synthesizing the voltage vector direction through the potential difference at the ends of the four probes, the direction of the leakage point / discharge point is determined according to the direction of the vector. For example, the synthesized voltage is V S , its direction is from O to S, then continue to -V S direction detection until the leakage point or discharge point is found.

[0037] In one embodiment, the specific installation position of the circuit control board is not limited, and it can be located underwater or above water. The circuit control board 1 and the four probes are wrapped with insulating materials, and only the ends of the four probes are exposed, so that the ends of the four probes are in contact with the water area.

[0038] In one embodiment, the circuit control panel 1 is placed above the water area and is wrapped with insulating material and / or waterproof material.

[0042] In this embodiment, the wireless WiFi module sends "detection data + number" information to an external computer, where "detection data" represents the detected voltage direction and "number" represents the circuit control board number, which makes it convenient for staff to quickly locate the water area where leakage occurs and the approximate direction of the leakage voltage.

[0043] In one embodiment, it also includes: a power supply module 14 and a power supply voltage detection circuit 15 electrically connected to the central processing unit 12, the power supply module 14 is used to supply power to the circuit control board 1, and the power supply voltage detection circuit 15 is used to detect the power supply voltage of the power supply module 14.

[0050] In one embodiment, each water area voltage detection device is assigned a unique number, and the voltage detection information sent wirelessly includes: voltage direction + number. For example, the information of "detection data + number" is sent to an external computer, where "detection data" represents the detected voltage direction and "number" represents the circuit control board number, so that the staff can quickly locate the water area where leakage occurs and the approximate direction of the leakage voltage.

[0051] For example: When V OX ,V OY ,V OZ When the detection data is sent, for example, "VOX:17VOY:50VOZ:100" is sent, the staff can obtain the direction of the leakage point or discharge point based on the sum of the device number and the space vector.
