A monitoring device and method for water environment emergency warning

Abstract

The present invention discloses a monitoring device and method for water environment emergency warning, which relates to the technical field of environmental monitoring. The device comprises a hull, wherein a sampling device, a detection device and a supporting device are arranged above the hull. The hull is placed on the water surface and is moved to a designated position by a propeller. When the sampling device moves to the sampling location, the sampling device is lowered to the sampling location by a rope elevator. During sampling, water is sucked in by a rotating motor, a rotating shaft, a spiral blade and a hollow cylinder. Before the water enters, it is filtered to prevent large solids from being sucked in and causing the spiral blade to be stuck. After the water is sucked in, it enters a collection pipe through a pipe for storage. The rotation of the auxiliary rod can drive away the surrounding fish and prevent some impurities such as aquatic plants from entering the suction range. When the sampling device dives, it is protected by a protective block at the bottom to prevent the bottom of the device from contacting hard objects such as stones and causing damage.

However, the current equipment has the following problems: if the sampling port of the sampling device is not protected, aquatic plants or large solids may be sucked in, and in some complex water environments, sharp objects at the bottom may scratch the bottom of the sampling device, causing damage to the equipment and failure to work properly. Summary of the Invention

By placing the hull on the water surface, the propeller is driven by the driving assembly to make the hull reach the designated position. When the sampling device moves to the sampling location, the rope elevator is operated by driving motor 1, and the operation of the rope elevator causes the steel cable to extend downward.

[0007] According to the above technical solution, the collection pipe is connected to the hollow cylinder through pipe 1, and the output end of the rotating motor drives the rotating shaft to rotate, and the rotation of the rotating shaft drives the spiral blade to rotate. At this time, water is sucked into the hollow cylinder through the spiral blade, and a docking hole 1 is opened on the circumferential surface of the collection pipe.

[0008] According to the above technical solution, the detection device includes a fixed tube 1, a T-shaped rod, an elastic telescopic rod 1 and a liquid tank. The fixed tube 1 is fixedly installed on the right side of the rope elevator, the T-shaped rod is slidably installed on the inner wall of the fixed tube 1, the fixed end of the elastic telescopic rod 1 is fixedly installed on the top of the rope elevator, and the liquid tank is fixedly installed on the movable end of the elastic telescopic rod 1. The circumferential surface of the fixed tube 1 is provided with a docking hole 2. The interior of the liquid tank is provided with a PH solvent. When the sampling device moves upward, it drives the collecting tube to move. The movement of the collecting tube will contact the bottom of the T-shaped rod, causing the T-shaped rod to move upward. The movement of the T-shaped rod will compress the No. 2 spring. When the docking hole 1 of the collecting tube moves to overlap with the docking hole 2 of the fixed tube 1, the liquid in the collecting tube will enter the test tank through pipe 2.

[0009] According to the above technical solution, the detection device also includes a liquid storage tube, a No. 2 spring and a fixed tube 2. One side of the liquid storage tube is fixedly installed on the bottom of the liquid tank, the fixed tube 2 is fixedly installed on the fixed end of the elastic telescopic rod 1, the No. 2 spring is arranged between the fixed tube 2 and the liquid storage tube, and the liquid storage tube is driven to reset by the arranged No. 2 spring. The other side of the liquid storage tube is slidably installed on the inner wall of the fixed tube 2. The circumferential surface of the liquid storage tube is provided with a docking hole 3. When the T-shaped rod moves upward, it contacts the liquid storage tube to cause it to move upward. The movement of the liquid storage tube drives the liquid tank to move and at the same time causes the movable end of the elastic telescopic rod 1 to move upward.

[0010] According to the above technical solution, the detection device also includes a liquid storage tube, a No. 2 spring, a second fixed tube, a test tank, a second drive motor, a mixing rod, a detector and a warning light. One side of the liquid storage tube is fixedly installed at the bottom of the liquid tank, the second fixed tube is fixedly installed at the fixed end of the elastic telescopic rod, the No. 2 spring is arranged between the second fixed tube and the liquid storage tube, and the other side of the liquid storage tube is slidably installed on the inner wall of the second fixed tube. The test tank is fixedly installed on the surface of the rope hoist, the fixed end of the second drive motor is arranged at the top of the test tank, and the mixing rod is fixedly installed at the output end of the second drive motor. After the PH solvent and the sampled water enter the test tank, the mixing rod is driven to rotate by the output end of the second drive motor, and the two are mixed through the mixing rod. The detector is fixedly installed on the inner wall of the test tank, and the warning light is arranged at the top of the rope hoist. The detector is electrically connected to the warning light. The mixed liquid is tested by the detector. When it exceeds a predetermined value, the warning light is always on to alert the onshore operator.

[0011] According to the above technical solution, one side of the test tank is connected to the fixed tube one through the pipe two, and the other side of the test tank is connected to the fixed tube two through the pipe three. The circumferential surface of the liquid storage tube is provided with a docking hole three. When the docking hole three of the liquid storage tube moves to overlap with the docking hole three of the fixed tube two, the pH solvent in the liquid storage tube will enter the test tank through the pipe three.

[0012] According to the above technical solution, the supporting device includes a driving plate, a waterproof plate, a fixing rod and a limiting rod. The driving plate is fixedly mounted on the top of the hull, the waterproof plate is rotatably mounted on the inner wall of the hull, a No. 1 torsion spring is arranged between the waterproof plate and the hull, and the waterproof plate is driven to reset by the arranged No. 1 torsion spring, the fixing rod is fixedly mounted on the outer wall of the driving assembly, the limiting rod is fixedly mounted on the fixed end of the elastic telescopic rod 2, and a slot is provided on the top of the limiting rod. The initial state of the movable end of the elastic telescopic rod 2 is a compressed state and is restricted by the limiting rod at this time. The fixed end of the elastic telescopic rod 2 moves to drive the limiting rod to move forward. When the limiting rod moves, its slot contacts the inclined surface of the limiting block, causing the limiting block to move downward while compressing the No. 3 spring. At this time, the movable end of the elastic telescopic rod 2 is released.

[0013] According to the above technical solution, the support device also includes a limit block, an air cushion and a driving rod. The limit block is slidably installed on the inner wall of the fixed rod. A No. 3 spring is arranged between the limit block and the fixed rod. The limit block is reset by the No. 3 spring. The top of the limit block is set to a triangle. The air cushion is set at the movable end of the elastic telescopic rod 2. 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 cause the waterproof board to 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 water environment emergency warning monitoring device comprises the following steps:

[0015] Step 1: Place the hull on the water surface and drive the propeller through the drive assembly to move the hull to the designated position. When the sampling device moves to the sampling location, the rope elevator is activated by driving motor 1. The rope elevator extends downward to drive the sampling device to dive for sampling.

[0016] Step 2: When the water surface is reached, the counterweight is used to balance the sealed box so that it can be moved to deeper waters. When sampling, the spiral blade rotates to suck water into the 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 being sucked in, the water enters the collection pipe through pipe 1 for storage;

[0017] Step 3: The auxiliary rod can be rotated to 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 rope hoist is used to retract the steel cable to reset the sampling device.

[0018] The present invention provides a monitoring device and method for water environment emergency warning, which has the following beneficial effects:

[0019] (1) The invention sets up a sampling device, places the hull on the water surface, and drives the propeller through the driving assembly to make the hull reach the designated position. 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 pipe 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.

[0020] (2) This invention, through the setting of the detection device, allows the sampling liquid in the collection tube to enter the test tank through the collection tube and the T-shaped rod through the pipe 2, and allows the pH solvent in the liquid tank to enter the test tank through the 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. 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. After the pH solvent and sampled water enter the test tank, the output end of the driving motor 2 drives the mixing rod to rotate. The mixing rod can optimize the detection conditions, reduce errors and uncertainties in the detection process, thereby improving 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 predetermined value, the warning light is always on to alert the onshore operator.

[0021] (3) This 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 air cushion storage area 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 retractable 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 retracted device is easier to carry and install. BRIEF DESCRIPTION OF THE DRAWINGS

The auxiliary rod 12 is fixedly installed on the circumferential surface of the rotating shaft 9. The rotation of the auxiliary rod 12 can drive away the surrounding fish and prevent some impurities such as aquatic plants from entering the suction range. The protective block 13 is slidably installed on the inner wall of the rotating shaft 9. 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. The No. 1 spring 14 is arranged between the protective block 13 and the auxiliary rod 12, and the protective block 14 is reset by the set No. 1 spring 14. The collecting tube 15 is fixedly installed on the inner wall of the sealed box 5.

[0033] The collecting pipe 15 is connected to the hollow cylinder 7 through a pipe 1. A docking hole 1 is provided on the circumferential surface of the collecting pipe 15. After being sucked in, water enters the collecting pipe 15 through the pipe 1 and is stored.

[0034] A method for using a water environment emergency warning monitoring device comprises the following steps:

[0035] 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 motor 1 3 is driven to make the rope hoist 2 work. The rope hoist 2 works to make the steel cable 4 extend downward and drive the sampling device to dive for sampling.

[0036] Step 2: When reaching the water surface, the counterweight 6 is used to balance the sealed box 6 so that it can be moved to deeper waters. When sampling, the spiral blade 10 rotates to suck water into the hollow cylinder 7. Before entering, the water is filtered through the filter 11 to prevent large solids from being sucked in and causing the spiral blade 10 to get stuck. After being sucked in, the water enters the collection pipe 15 through the pipe 1 for storage;

[0037] Step 3: The auxiliary rod 12 is rotated to drive away the surrounding fish and prevent impurities such as water plants from entering the suction range. When the sampling device dives, the protective block 13 at the bottom is used to protect it from contacting hard objects such as stones and causing damage. After the sampling is completed, the rope hoist 2 is used to retract the steel cable 4, so that the sampling device is reset.

[0038] When this embodiment is working, the hull 1 is placed on the water surface, and the propeller is driven by the driving component to make the hull 1 reach the specified position. When the sampling device moves to the sampling location, the rope hoist 2 is operated by the driving motor 13. The rope hoist 2 works to extend the steel cable 4 downward. The extension of the steel cable 4 drives the sealing box 5 to move. When reaching the water surface, the counterweight 6 is used to balance the weight so that the sealing box 5 can move to deeper waters. When sampling, the output end of the rotating motor 8 drives the rotating shaft 9 to rotate, and the rotation of the rotating shaft 9 drives the spiral piece 10 to rotate. At this time, water is sucked into the hollow cylinder 7 through the spiral piece 10. The water first enters the hollow cylinder 7. The water is filtered through the filter 11 to prevent large solids from being sucked in and causing the spiral 10 to get stuck. After the water is sucked in, it enters the collection pipe 15 through 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.

[0039] See also Figures 1-8 On the basis of the above embodiment, in another embodiment of the present invention, a detection device and a supporting device are provided above the hull 1, and the detection device includes a fixed tube 20, a T-shaped rod 21, an elastic telescopic rod 22 and a liquid tank 23.

The detector 210 is electrically connected to the warning light 211. Traditional monitoring methods may require collecting water samples and sending them back to the laboratory for analysis. This process may take a long time. 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.

[0041] 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.

[0042] The detection device also includes a slider 212, a threaded rod 213 and an elastic telescopic rod 214. One side of the slider 212 is fixedly mounted on the bottom of the rope hoist 2, the threaded rod 213 is fixedly mounted on the output end of the drive assembly, and the other side of the slider 212 is threadedly mounted on the circumferential surface of the threaded rod 213. The fixed end of the elastic telescopic rod 214 is fixedly mounted on the right side of the rope hoist 2. The sampling device can be stored after sampling is completed.

[0043] The supporting device includes a driving plate 30, a waterproof plate 31, a fixing rod 32 and a limiting rod 33. The driving plate 30 is fixedly installed on the top of the hull 1, and the waterproof plate 31 is rotatably installed on the inner wall of the hull 1. A No. 1 torsion spring is arranged between the waterproof plate 31 and the hull 1, and the No. 1 torsion spring is used to drive the waterproof plate 31 to reset. The fixing rod 32 is fixedly installed on the outer wall of the driving assembly, and the limiting rod 33 is fixedly installed on the fixed end of the elastic telescopic rod 214. A card slot is provided on the top of the limiting rod 33 to prevent the storage area of ​​the air cushion 35 from being submerged in water.

[0044] The supporting device also includes a limit block 34, an air cushion 35 and a driving rod 36. The limit block 34 is slidably installed on the inner wall of the fixed rod 32. A No. 3 spring is arranged between the limit block 34 and the fixed rod 32. The limit block 34 is reset by the No. 3 spring. The top of the limit block 34 is arranged as a triangle. The air cushion 35 is arranged at the movable end of the elastic telescopic rod 214. One side of the driving rod 36 is fixedly installed at the movable end of the elastic telescopic rod 214. 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, it may encounter wind and waves, which causes the hull 1 to shake and thus affect the sampling. At this time, the shaking condition is alleviated by establishing support on the water surface through the air cushions 35 on both sides.

[0045] When the present embodiment is working, the upward movement of the sampling device drives the collecting tube 15 to move, and 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. The T-shaped rod 21 moves upward and contacts the liquid storage tube 24, causing it to move upward. The movement of the liquid storage tube 24 drives the liquid tank 23 to move and simultaneously 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 sampled water enter the test tank 27, the output end of the driving motor 28 drives the mixing rod 29 to rotate. The mixing rod 29 allows the two to be mixed, which can optimize the detection conditions, reduce errors and uncertainties in the detection process, thereby improving 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. 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. 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. The sampling device can be stored after the sampling is completed.

[0046] The initial state of the movable end of the elastic telescopic rod 214 is a compressed state and is restricted by the limit rod 33 at this time. The fixed end of the elastic telescopic rod 214 moves and drives the limit rod 33 to move forward. When the limit rod 33 moves, its slot contacts the inclined surface of the limit block 34, causing the limit block 34 to move downward while compressing the No. 3 spring. 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 contacts the waterproof board 31, causing the waterproof board 31 to rotate, and finally causes the air cushion 35 to 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 flooded, which may encounter wind when the sampling device is sampling. The waves cause the hull 1 to shake, thereby affecting the sampling. At this time, the shaking condition is 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 and convenient for operation and transportation. In particular, when the sampling location needs to be moved frequently, the contracted device is easier to carry and install.

6. A method for using a water environment emergency warning monitoring device, using the water environment emergency warning monitoring device according to claim 5, characterized in that: The following steps are involved: Step 1: Place the hull on the water surface and drive the propeller through the drive assembly to move the hull to the designated position. When the sampling device moves to the sampling location, the rope elevator is activated by driving motor 1. The rope elevator extends downward to drive the sampling device to dive for sampling. Step 2: When the water surface is reached, the counterweight is used to balance the sealed box so that it can be moved to deeper waters. When sampling, the spiral blade rotates to suck water into the 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 being sucked in, the water enters the collection pipe through pipe 1 for storage; Step 3: The auxiliary rod can be rotated to 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 rope hoist is used to retract the steel cable to reset the sampling device.
