[0013] According to the above technical solution, the supporting device also includes a limit block, an air cushion and a driving rod.

One side of the driving rod is fixedly installed at the movable end of the elastic telescopic rod 2. The other side of the driving rod is slidably installed on the inner wall of the driving plate. The movement of the elastic telescopic rod 2 drives the air cushion to move. At this time, the air cushion will contact the waterproof board to make the waterproof board rotate, and finally the air cushion will move out of the waterproof board. At this time, the waterproof board is reset by the No. 1 torsion spring.

[0014] A method for using a monitoring device for water environment emergency warning comprises the following steps: Step 1: Place the hull on the water surface and drive the propeller through the driving assembly to make the hull reach the designated position. When the sampling device moves to the sampling location, the rope elevator is driven by the driving motor 1, and the rope elevator is operated to extend the steel cable downward to drive the sampling device to dive for sampling; Step 2: When reaching the water surface, the sealed box is weighted by a counterweight so that it can be moved to deeper waters. When sampling, the spiral blade rotates so that water is sucked into the hollow cylinder. Before entering, the water is filtered through a filter to prevent large solids from being sucked in and causing the spiral blade to get stuck. After being sucked in, the water enters the collection tube through pipe 1 for storage; Step 3: By rotating the auxiliary rod, you can drive away the surrounding fish and prevent impurities such as water plants from entering the suction range. When the sampling device dives, it is protected by the protective block at the bottom to prevent the bottom of the sampling device from contacting hard objects such as stones and causing damage. After the sampling is completed, the steel cable is retracted through the rope hoist to reset the sampling device.

[0015] The present invention provides a monitoring device and method for water environment emergency warning, which has the following beneficial effects: (1) The invention, through the setting of the sampling device, places the hull on the water surface, drives the propeller through the driving assembly to make the hull reach the designated position, and when the sampling device moves to the sampling location, it drives the motor 1, rope hoist, steel cable, sealing box, and counterweight block to make the sampling device dive to the sampling location. When sampling, water is sucked in by rotating the motor, shaft, spiral blade, and hollow cylinder. Before entering, the water is filtered through the filter to prevent large solids from being sucked in and causing the spiral blade to get stuck. After the water is sucked in, it enters the collection tube through the pipe 1 for storage. The auxiliary rod can be rotated to drive away the surrounding fish and prevent some impurities such as water plants from entering the suction range. When the sampling device dives, it is protected by the protective block at the bottom to prevent the bottom of the sampling device from contacting hard objects such as stones and causing damage. After the sampling is completed, the steel cable is retracted by the rope hoist to reset the sampling device.

[0016] (2) The present invention, through the setting of the detection device, allows the sampling liquid in the collection tube to enter the test tank through pipe 2 through the collection tube and T-shaped rod, and allows the pH solvent in the liquid tank to enter the test tank through pipe 3 through the liquid storage tube. The traditional monitoring method may require the water sample to be collected and sent back to the laboratory for analysis, which may take a long time. However, by directly testing after sampling, water quality data can be obtained in a short time, which is crucial for emergency response in sudden environmental events. After the pH solvent and sampled water enter the test tank, the mixing rod is driven to rotate by the output end of the driving motor 2. The mixing rod can optimize the detection conditions and reduce the errors and uncertainties in the detection process, thereby improving the detection efficiency and obtaining accurate pH value data more quickly. This is particularly important in water environment emergency warning monitoring and can provide data support for decision-making in a timely manner. The mixed liquid is tested by the detector. When it exceeds the preset value, the warning light is always on to prompt the onshore operators.

[0017] (3) The invention, through the setting of the support device, releases the movable end of the second elastic telescopic rod through the limit rod and the limit block, and drives the air cushion to move at the same time. After the air cushion is moved out, the waterproof plate is used to prevent the storage area of ​​the air cushion from being flooded. When the sampling device is sampling, it may encounter wind and waves, which causes the hull to shake and thus affect the sampling. At this time, the air cushions on both sides are used to establish support on the water surface to alleviate the shaking condition. When the sampling device is stored, the limit rod is fixed by the limit block, and finally the air cushion is reset to the storage area. The contraction of the support device can make the sampling device more compact and convenient for operation and transportation. Especially when the sampling location needs to be moved frequently, the contracted device is easier to carry and install. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] A method for using a monitoring device for water environment emergency warning comprises the following steps: Step 1: Place the hull 1 on the water surface, and drive the propeller through the driving assembly to make the hull 1 reach the designated position. When the sampling device moves to the sampling location, the driving motor 1 3 is used to drive the rope hoist 2, and the rope hoist 2 works to extend the steel cable 4 downward to drive the sampling device to dive for sampling; Step 2: When reaching the water surface, the weight is counterbalanced by the weight block 6 so that the sealed box 6 can be moved to a deeper water area.

After the water is sucked in, it enters the collecting tube 15 through the pipe 1 for storage. The rotation of the rotating shaft 9 drives the auxiliary rod 12 to rotate. The rotation of the auxiliary rod 12 can drive away the surrounding fish and prevent some impurities such as water plants from entering the suction range. When the sampling device dives, it is protected by the protective block 13 at the bottom. The protective block 13 is squeezed to compress the No. 1 spring 14 to prevent the bottom of the sampling device from contacting hard objects such as stones and causing damage. After the sampling is completed, the steel cable 4 is retracted through the rope hoist 2 to reset the sampling device.

Traditional monitoring methods may require the water samples to be collected and sent back to the laboratory for analysis. This process may take a long time. However, by directly testing after sampling, water quality data can be obtained in a short time, which is crucial for emergency response in sudden environmental events.

[0027] One side of the test tank 27 is connected to the fixed tube 1 20 through the pipe 2, and the other side of the test tank 27 is connected to the fixed tube 2 26 through the pipe 3. When the docking hole 1 of the collection tube 15 moves to overlap with the docking hole 2 of the fixed tube 1 20, the liquid in the collection tube 15 will enter the test tank 27 through the pipe 2. The circumferential surface of the liquid storage tube 24 is provided with a docking hole 3.

The other side of the driving rod 36 is slidably installed on the inner wall of the driving plate 30. When the sampling device is sampling, wind and waves may be encountered, which causes the hull 1 to shake and thus affect the sampling. At this time, the shaking condition can be alleviated by establishing support on the water surface through the air cushions 35 on both sides.

[0031] When the present embodiment is working, when the sampling device moves upward, it drives the collecting tube 15 to move. The movement of the collecting tube 15 will contact the bottom of the T-shaped rod 21, causing the T-shaped rod 21 to move upward. The movement of the T-shaped rod 21 will compress the second spring 25. When the docking hole 1 of the collecting tube 15 moves to overlap with the docking hole 2 of the fixed tube 1 20, the liquid in the collecting tube 15 will enter the test tank 27 through the pipe 2. While the T-shaped rod 21 moves upward, it contacts the liquid storage tube 24, causing it to move upward. The movement of the liquid storage tube 24 drives the liquid box 23 to move and causes the movable end of the elastic telescopic rod 1 22 to move upward. When the docking hole 3 of the liquid storage tube 24 moves to overlap with the docking hole 3 of the fixed tube 2 26, the PH solvent in the liquid storage tube 24 will enter the test tank 27 through the pipe 3. The traditional monitoring method may require the water sample to be collected and sent back to the laboratory for analysis. This process may take a long time. However, directly testing after sampling can obtain water quality data in a short time. This is crucial for emergency response in sudden environmental events. After the pH solvent and the sampled water enter the test tank 27, the mixing rod 29 is driven to rotate by the output end of the driving motor 28. The mixing of the two by the mixing rod 29 can optimize the detection conditions, reduce errors and uncertainties in the detection process, thereby improving the detection efficiency and obtaining accurate pH value data more quickly. This is particularly important in water environment emergency warning monitoring, and can provide data support for decision-making in a timely manner. The mixed liquid is tested by the detector 210. When it exceeds the predetermined value, the warning light 211 is always on to prompt the onshore operator. The threaded rod 213 is rotated by the driving component, and the rotation of the threaded rod 213 causes the slider 212 to slide. The movement of the slider 212 drives the rope hoist 2 to move forward, and the movement of the rope hoist 2 drives the sampling device to move. The rope hoist 2 moves and drives the fixed end of the elastic telescopic rod 214 to move. After the sampling is completed, the sampling device can be stored; The initial state of the movable end of the elastic telescopic rod 214 is a compressed state and is limited by the limit rod 33 at this time. The fixed end of the elastic telescopic rod 214 moves to drive the limit rod 33 to move forward. When the limit rod 33 moves, its card slot will contact the inclined surface of the limit block 34, causing the limit block 34 to move downward and compress the No. 3 spring at the same time. At this time, the movable end of the elastic telescopic rod 214 is released, and the movement of the elastic telescopic rod 214 drives the air cushion 35 to move. At this time, the air cushion 35 will contact the waterproof board 31 to cause the waterproof board 31 to rotate, and finally the air cushion 35 will move out of the waterproof board 31. At this time, the waterproof board 31 is reset by the No. 1 torsion spring to prevent the storage area of ​​the air cushion 35 from being submerged in water. When the sampling device is sampling, it may encounter wind. The waves cause the hull 1 to shake, thus affecting the sampling. At this time, the shaking condition can be alleviated by establishing support on the water surface through the air cushions 35 on both sides. When the sampling device is stored, the movable end of the elastic telescopic rod 214 drives the driving rod 36 to move, and the driving rod 36 will move along the driving plate 30, so that the movable end of the elastic telescopic rod 214 is gradually compressed until it is reset, and after the limit rod 33 moves to contact the inclined surface of the limit block 34, the limit rod 33 is fixed by the limit block 34, and finally the air cushion 35 is reset to the storage area. The contraction support device can make the sampling device more compact, easy to operate and transport, especially when the sampling location needs to be moved frequently, the contracted device is easier to carry and install.
