Description

Technical Field

[0001] This utility model belongs to the field of water monitoring technology, specifically relating to a mobile water quality monitoring device. Background Technology

[0002] Traditional fixed water quality monitoring stations have limited coverage, typically collecting data only at fixed points, and cannot reflect the dynamic changes in water quality across the entire river basin. Manual sampling and testing requires significant manpower and resources, and suffers from long testing cycles and data dispersion. Existing manual river inspection systems primarily assess water turbidity and other indicators through visual inspection by inspectors. This method cannot determine the content of substances in the water and is easily affected by environmental factors such as lighting conditions and observation angle.

[0003] Chinese utility model patent publication number CN 218067926U discloses an unmanned vessel-borne wireless intelligent water quality sensor. This patented device can eliminate the reliance on cables in traditional monitoring processes, achieving intelligent water quality monitoring and thus improving its efficiency. It can realize underwater data acquisition and storage functions. However, this device can only collect data at fixed points and cannot perform water quality monitoring across an entire body of water.

[0004] Chinese utility model patent CN 208155988U discloses an unmanned surface vessel (USV) for water environment monitoring, which is flexible and easy to operate. Chinese invention patent CN 110435829A discloses an USV for river water quality monitoring, which employs a swing mechanism to allow the water quality sensor to leave the water body when not in use, avoiding prolonged immersion. However, neither of these patents allows for adjustment of the water quality sensor's measurement depth, enabling detection of water quality at different depths, and the sensor's swing due to water flow can easily affect measurement accuracy.

[0005] Based on this need, there is an urgent need for a water quality monitoring device that is not affected by geographical location or complex water conditions, ensuring the timeliness and comprehensiveness of the collected water quality data, and helping to quickly deploy and accurately locate specific pollution events or emergencies. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a mobile water quality monitoring device for realizing water quality monitoring of the entire river channel.

[0007] To achieve the above objectives, a mobile water quality monitoring device is designed, which is installed on the side of a ship and includes...

[0008] U-shaped plate connected to the top of the ship's hull;

[0009] A fixing plate that connects to the lower outer side of the ship's hull;

[0010] A hollow telescopic link, the link comprising

[0011] The first fixing rod is located at the top and is connected to the U-shaped plate.

[0012] The second fixing rod is located at the bottom, and the bottom of the second fixing rod is connected to the water quality sensor. One side of the second fixing rod is connected to the fixing plate.

[0013] The telescopic rod located in the middle can adjust the length of the connecting rod.

[0014] Preferably, the top of the telescopic rod is fitted inside the first fixed rod, and the top of the second fixed rod is fitted inside the telescopic rod.

[0015] Preferably, the signal line of the water quality sensor passes through the top of the first fixed rod and is connected to the water quality sensor through the hollow structure of the telescopic connecting rod.

[0016] Preferably, the fixing plate is provided with a U-shaped buckle, which is used to connect the water quality sensor.

[0017] Compared with the prior art, the advantages of this utility model are:

[0018] 1. The fixed rod structure can prevent damage to the hull, and the telescopic rod can be freely adjusted in length to detect water parameters at different depths. The measurement accuracy will not be affected by the swaying of the sensor due to water flow. It is not affected by geographical location or complex water conditions and can travel freely in any corner of the river.

[0019] 2. Water quality sensors can be selected as needed to adapt to different water quality monitoring conditions, making operation more flexible.

[0020] 3. Water quality parameters can be viewed in real time on the display screen and can also be uploaded to the cloud to achieve full-coverage online collection of water quality parameters, ensuring the timeliness and comprehensiveness of the collected water quality data, and helping to quickly deploy and accurately locate specific pollution events or emergencies.

Two rows of four hexagonal bolts 3 are evenly arranged on the U-shaped plate 11. A gasket 9 is placed between the hexagonal bolts 3 and the U-shaped plate 11. The U-shaped plate 11 is connected to a first fixing rod 8. The signal line 12 of the water quality sensor is vertically inserted from the top of the first fixing rod 8. The lower part of the first fixing rod 8 is connected to a telescopic rod 7. The lower part of the telescopic rod 7 is connected to a second fixing rod 6. The top of the telescopic rod 7 is fitted inside the first fixing rod 8. The top of the second fixing rod 6 is fitted inside the telescopic rod 7. The telescopic rod 7, the first fixing rod 8 and the second fixing rod 6 are used to adjust the length of the connecting rod. The connecting rod has a hollow structure.
