Description

TECHNICAL FIELD

[0002] Fishery resources refer to the total body of fish, crustaceans, mollusks, algae and marine mammals with development and utilization value in natural waters. Fishery resources play a crucial role in maintaining water ecological balance and ensuring sustainable development of fisheries. With the increasing problems of non-compliance with industrial wastewater discharge, intensified agricultural non-point source pollution and random dumping of domestic sewage, the water quality of fishery waters has been threatened. Water pollution not only leads to deterioration of the living environment of aquatic organisms such as fish, decline in reproductive capacity, and increase in disease incidence, but also may cause mass mortality, directly affecting fishery production and fishermen's income.

[0003] Prior art one (Chinese patent with publication number CN221883608U and publication date 2024-10-22) is an environmental monitoring device for surface water pollution prevention and control, which relates to the technical field of environmental monitoring. It includes a monitoring device block with a device cavity inside. By setting an adjustment structure, it can monitor surface water at different depths, avoiding the problem that traditional environmental monitoring equipment for surface water pollution prevention and control can only monitor surface water at a fixed depth and cannot monitor surface water at multiple depths. The monitoring effect is better, ensuring the accuracy of the equipment in monitoring surface water. The equipment is suitable for surface water of various depths, avoiding the problem that traditional environmental monitoring equipment for surface water pollution prevention and control cannot adjust the monitoring depth, leading to the inability to use the equipment in some specific surface water monitoring locations. It saves the cost of purchasing new equipment, reduces the cost in the environmental monitoring process, and greatly improves the use effect of the equipment.

[0004] There is also prior art two (Chinese patent with publication number CN116429995B and publication date 2025-08-08), a breeding tail water pollution monitoring device and method. For breeding tail water pollution detection, the device can be placed on the corridor platform, then moved along the corridor platform, and when it moves to a specific position, the detection rod is inserted into the breeding tail water to complete the detection of the corresponding parameters. And through the setting of the left and right clamping positioning wheel groups, the position of the mobile car on the corridor platform can be moved more accurately, avoiding deviation from the center, so that the detection rods on both sides can ensure better position equality when detecting the breeding tail water on both sides, that is, the distance between the detection rods and the position of the corridor platform is controllable, and the detection position of the detection rods on both sides can be controlled more accurately through the action of the lifting drive.

[0005] Although the prior art can adjust the detection position, in the actual fishery water environment, there are often problems such as entanglement of aquatic plants, attachment of plankton and sediment deposition, and these impurities are easy to attach to the sampling port or sensor surface of the monitoring device, affecting the monitoring accuracy and device life, and when the prior art is used for different depth water quality monitoring, the monitoring components are directly in contact with the water body, and after long-term use, they are easy to be polluted and blocked, and during the non-monitoring period, the monitoring components are still exposed in the water body, which accelerates the wear and aging of the components, increases the maintenance cost and frequency.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Example 1: In actual fishery water monitoring, water bodies may have localized stagnant areas or concentration gradients due to various factors, such as differences in water flow velocity and biological activity. Without agitation, the water sample entering monitoring tank 6 may not accurately reflect the water quality of the entire monitoring area, leading to biased monitoring results. Figures 1-6The present invention provides the following technical solution: a fishery resource water pollution monitoring device, wherein a fixed box 2 is fixedly connected to the side of the mounting frame 1, and an adjusting screw 3 is rotatably connected to the upper part of the fixed box 2, and a sleeve 5 is slidably arranged inside the lower part of the fixed box 2; a detection screen 4 is arranged on the outer side of the fixed box 2; a monitoring tank 6 is fixedly connected to the lower end of the sleeve 5, and a monitoring instrument 21 for monitoring water quality is fixedly connected inside the monitoring tank 6; the sleeve 5 is threaded to the outer side of the adjusting screw 3, and limit blocks 13 are fixedly connected to the front and rear sides of the outer side of the sleeve 5. The inner wall of the fixed box 2 is provided with a sliding groove 14. The limiting block 13 is slidably connected inside the sliding groove 14. The left and right sides of the fixed box 2 are rotatably connected with connecting rods 10. The inner side of the connecting rod 10 is fixedly connected with a contact rod 11, and the outer side of the connecting rod 10 is fixedly connected with a water stirring rod 8. The side of the connecting rod 10 is fixedly connected with a torsion spring 9 between it and the fixed box 2. The left and right sides of the sleeve rod 5 are fixedly connected with contact frames 12 at equal intervals. When the sleeve rod 5 moves vertically, the contact frames 12 and the contact rod 11 collide, and the water stirring rod 8 is rotated through the connecting rod 10. The water stirring rod 8 is used to agitate the water.

[0025] When the user needs to adjust the monitoring position to obtain data from different water depths, they only need to manually rotate the adjusting screw 3. The adjusting screw 3 and the sleeve 5 are connected by a threaded design. When the adjusting screw 3 rotates, based on the transmission principle of the thread, a force is generated that causes the sleeve 5 to move. At the same time, the limiting block 13 is installed on the sleeve 5, and the sliding groove 14 is formed on the inner wall of the fixing box 2. The two work together to form a precise limiting structure. The limiting block 13 and the sliding groove 14 effectively restrict the rotational freedom of the sleeve 5, so that the sleeve 5 will not move with the adjusting screw 3 when the adjusting screw 3 rotates. As the sleeve rod 5 rotates downwards, it causes the monitoring bucket 6, which is fixedly connected to its lower end via a sturdy connector, to move downwards as well. The protective outer cylinder 7 also moves downwards along with the monitoring bucket 6, allowing the entire monitoring assembly to penetrate deep into the fishery waters to be monitored. During the vertical movement of the sleeve rod 5 along the interior of the fixing box 2, the contact frames 12, installed on both sides of the sleeve rod 5 and fixedly connected at equal intervals, will move vertically in sync with the movement of the sleeve rod 5. When the contact frames 12 gradually move and come into contact with the contact rod 11, the contact frames 12 will... The abutment rod 11 applies a horizontal abutment force. Since the connecting rod 10 and the fixed box 2 are connected by a rotating shaft, the connecting rod 10 rotates around the rotating shaft under the influence of the abutment force. As the connecting rod 10 rotates, the stirring rod 8 also rotates. As the sleeve rod 5 continues to move downwards, the abutment frame 12 also continues to move downwards. At this time, the contact state between the abutment frame 12 and the abutment rod 11 gradually changes, and the abutment frame 12 gradually disengages from the abutment rod 11. When the abutment rod 11 is no longer subjected to the abutment force of the abutment frame 12, the connecting rod 10 rotates. Under the elastic force generated by the release of the elastic potential energy stored in the torsion spring 9, the connecting rod 10 will rotate in the opposite direction around the rotation axis, thereby driving the water stirring rod 8 fixedly connected to its outer side to rotate and reset. During the rotation, the water stirring rod 8 will generate a strong stirring effect on the water around the monitoring tank 6. This stirring can break the original static state of the water, make the water in the monitoring area fully mixed and uniform, and ensure that the water sample entering the monitoring tank 6 later is more representative, thereby significantly improving the accuracy and reliability of the monitoring data and providing strong data support for the scientific management and decision-making of fishery waters.

[0026] Example 2: Figures 7-11The present invention provides the following technical solution: a fishery resource water pollution monitoring device, wherein a protective outer cylinder 7 is sleeved on the outside of the monitoring tank 6, and an adjustment mechanism is provided between the inner side of the protective outer cylinder 7 and the inside of the monitoring tank 6. The adjustment mechanism adjusts the position of the protective outer cylinder 7 by rotating the support frame 17 it includes in the positive direction, so that water can enter the monitoring tank 6 for monitoring. The adjustment mechanism includes a driver 23, which is fixedly connected to the inside of the monitoring tank 6, and the lower output shaft end of the driver 23 is fixedly connected to the support frame 17. A limiting groove 18 is opened on the monitoring tank 6, and the outer end of the support frame 17 is slidably connected to the inside of the limiting groove 18. The outer end of the support frame 17 is fixedly connected to the protective outer cylinder 7, and an auxiliary hole 20 is opened on the periphery of the protective outer cylinder 7. A water inlet hole 19 for water to enter is opened on the periphery of the monitoring tank 6. When the support frame 17 is in the initial position, the auxiliary hole 20 and the water inlet hole 19 do not correspond, and water cannot enter the monitoring tank 6 through the water inlet hole 19.

[0027] When the device receives a water quality monitoring command, the driver 23 starts and drives the connected support frame 17 to rotate in a positive direction. During the rotation, the support frame 17 is ensured to rotate smoothly by the limiting groove 18, avoiding swaying or deviation, thus ensuring the stability and reliability of the entire rotation process. When the support frame 17 rotates, the protective outer cylinder 7 rotates synchronously with the support frame 17 at the same angle. During the rotation of the protective outer cylinder 7, the auxiliary holes 20 evenly distributed on its periphery gradually rotate to correspond to the positions of the water inlet holes 19 set on the periphery of the monitoring tank 6. In the initial state, the protective outer cylinder 7 can provide effective protection for the monitoring tank 6, preventing debris, organisms, etc. in the water from damaging the monitoring tank 6, ensuring the accuracy and stability of the monitoring data. The sealing airbag 15 is tightly fitted to the position of the water inlet hole 19, preventing the water from entering the tank. The water inlet 19 provides a good seal. As the outer protective cylinder 7 rotates, the sealing airbag 15 also shifts position, gradually moving away from the water inlet 19, thus releasing the seal on the water inlet 19. When the auxiliary hole 20 is completely aligned with the water inlet 19 and the sealing airbag 15 is completely offset from the water inlet 19, the external water, under its own pressure, flows smoothly into the monitoring tank 6 through the auxiliary hole 20 and the water inlet 19. A high-precision monitoring instrument 21 is installed inside the monitoring tank 6. The monitoring instrument 21 has multiple monitoring functions and can analyze and detect various indicators in the water sample in real time and accurately, such as pH, dissolved oxygen content, and heavy metal content. The water sample entering the monitoring tank 6 provides a reliable test sample for the monitoring instrument 21, enabling it to obtain accurate water quality data and provide a scientific basis for subsequent water quality assessment and decision-making.

[0028] Example 3: The monitoring tank 6 contains high-precision instruments and sensitive components. If water or impurities enter, they may contaminate the monitoring environment, leading to inaccurate monitoring data, or even damaging internal components, affecting the normal operation and lifespan of the equipment. To solve this problem, such as... Figures 7-11 The present invention provides the following technical solution: a fishery resource water pollution monitoring device, wherein a sealing mechanism is provided between the inner wall of the monitoring tank 6 and the interior of the protective outer cylinder 7. The sealing mechanism achieves sealing of the monitoring tank 6 by the reverse rotation of the support frame 17. The sealing mechanism includes a sealing airbag 15, which is fixedly connected to the inner wall of the protective outer cylinder 7. When the support frame 17 is in the initial position, the sealing airbag 15 and the water inlet 19 are located at the same position, and the inner side of the sealing airbag 15 is flush with the monitoring tank. The outer wall of the 6 is tightly fitted, and a connecting hose 22 is provided above the sealing airbag 15. An air storage airbag 16 is fixedly connected inside the monitoring tank 6, and the air storage airbag 16 is arranged in a ring structure. The air storage airbag 16 is connected to the other end of the connecting hose 22. An abutting airbag 24 is provided below the air storage airbag 16. A compression frame 25 is fixedly connected to the side of the support frame 17, and the compression frame 25 is positioned corresponding to the abutting airbag 24. When the support frame 17 rotates in the opposite direction, the compression frame 25 compresses the abutting airbag 24.

[0029] After the water quality monitoring is completed, the driver 23, located in the key power part of the equipment, drives the connected support frame 17 to rotate in the reverse direction. As the support frame 17 rotates, the protective outer cylinder 7 fixedly connected to it also rotates synchronously. The auxiliary holes 20 evenly distributed around the periphery of the protective outer cylinder 7 gradually misalign with the water inlet holes 19 at the corresponding positions around the periphery of the monitoring tank 6. When they are completely misaligned, an effective barrier is formed between the auxiliary holes 20 and the water inlet holes 19, initially preventing the entry of external water. The squeezing frame 25 installed on the side of the support frame 17 moves synchronously with the reverse rotation of the support frame 17, gradually approaching the contact airbag 24 located below the air storage airbag 16. When the squeezing frame 25 contacts the contact airbag 24, As the support frame 17 continues to rotate, the pressure applied by the compression frame 25 to the contact airbag 24 gradually increases. Under the action of pressure, the contact airbag 24 deforms, and the gas inside is forced into the storage airbag 16 through the preset channel. As the gas is continuously injected, the storage airbag 16 gradually expands. The gas inside the storage airbag 16 is quickly transported to the sealing airbag 15 through the connecting hose 22. The sealing airbag 15 begins to inflate and expand. Under the action of gas pressure, the inner side of the sealing airbag 15 is tightly attached to the outer wall of the monitoring tank 6, effectively preventing external water, impurities, etc. from entering the monitoring tank 6 during equipment movement or when not in use, and avoiding secondary pollution caused by leakage of residual water samples after monitoring is completed.

[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
