Description

Technical Field

[0001] This invention relates to the field of nearshore water pollution detection technology, specifically to a nearshore ecological early warning water pollution detector and its detection method. Background Technology

[0002] Nearshore water pollution detection is a core technology of marine ecological early warning systems. By periodically detecting key pollutant indicators, the health of the ecosystem is assessed, enabling relevant personnel to take timely and appropriate measures. For example, the marine water quality detection device with announcement number CN215415362U includes a detection device housing with a mounting frame on top; a signal receiver fixedly mounted on the right side of the mounting frame; a worktable fixedly mounted on top of the mounting frame, with a signal transmitter mounted above the worktable; a motor fixedly disposed inside the detection device housing, with a threaded screw connected to its output end, and a movable block on the surface of the threaded screw; and a detection body mounted on the surface of the movable block, with detection terminals inside. Compared to existing devices, this marine water quality detection device, through the action of the motor, threaded screw, and movable block, facilitates rapid delivery of the detection body to the target area for detection, enabling rapid marine water detection. The automatic operation of the motor saves detection time and improves work efficiency. For example, a marine water pollution detection device with announcement number CN213600694U includes a float and a remote control center. A base is fixedly connected to the lower end of the float, and a placement seat is fixedly mounted on one side of the upper surface of the float. A small wind turbine is fixedly mounted on the upper end of the placement seat. A microprocessor and a data storage module are fixedly mounted on the upper surface of the float away from the small wind turbine. A battery is fixedly mounted on the upper end of the microprocessor and data storage module. A through hole is fixedly opened in the middle of the interior of the float and the base. A water-proof plate is fixedly mounted on the outside of the through hole inside the base, and an upper fixing frame is fixedly mounted on the upper end of the through hole. This device has advantages such as real-time monitoring, speed, energy saving, high accuracy, convenient operation, wide monitoring range, and high flexibility. It has broad application prospects and significant social and economic benefits, and is worthy of promotion. However, the above-mentioned marine water quality detection device still has the following disadvantages in actual use: 1. Since water pollution detectors are used in nearshore areas, the waves are usually large. However, traditional water pollution detectors only have a single floating structure and cannot adjust the contact area between the floating structure and the sea surface according to the size of the waves, resulting in poor stability. 2. Furthermore, traditional water pollution detectors always keep the sampling structure submerged in seawater when extracting seawater at different depths. Therefore, each time seawater is extracted, there are residues from the previous extraction, affecting the accuracy of the test. Also, there is a lack of a structure to empty the inside of the sampling structure after the test.

[0003] To address the aforementioned issues, there is an urgent need for innovative designs based on existing water pollution detectors. Summary of the Invention

[0004] The purpose of this invention is to provide a nearshore ecological early warning water quality pollution detector and its detection method, so as to solve the problems mentioned in the background art: traditional water quality pollution detectors only have a single floating structure, cannot adjust the contact area between the floating structure and the sea surface according to the size of the waves, and lack a structure for emptying the interior of the sampling structure after detection.

[0006] Preferably, the adjustment mechanism includes a gear fixed to the output shaft of the first motor, and there are two gears, with two racks meshing on the sides of each gear. At the same time, the ends of the racks are fixedly connected to one end of the connecting rod. Through the meshing transmission of the gears and racks, the second floats distributed at equal angles can be driven to move away from or towards each other.

[0007] Preferably, the connecting rod slides through the side of the first float plate, and the other end of the connecting rod is fixed to the second float plate. The second float plate is hollow, and the two relatively distributed second float plates move in opposite directions. The arrangement of the second float plate can improve the stability of the device, and its hollow shape can reduce the overall weight of the device.

[0008] Preferably, the detection mechanism includes a detector installed on the upper surface of the protective box, and the bottom of the detector is connected to one end of the movable tube, and a connecting plate is fixed to the other end of the movable tube, while an inlet hole is opened at the edge of the connecting plate.

[0009] Preferably, the lower end face of the connecting plate is in contact with and rotates with the upper end face of the first float plate, and the upper end face of the first float plate is provided with connecting holes at equal angles. The connecting holes are interconnected with the liquid inlet and the movable tube, and the connecting holes are connected with the water pumping pipe. The sampled liquid is transmitted to the detector through the water pumping pipe, the connecting holes, the liquid inlet and the movable tube.

[0010] Preferably, the water pumping pipe is fixedly inserted through the interior of the first float plate, and the inner diameter of the middle section of the water pumping pipe is larger than the inner diameter of its two ends. The water pumping pipes are distributed at equal angles, and the lengths of adjacent water pumping pipes are different. At the same time, movable blocks are attached to and slide inside the water pumping pipe.

[0011] Preferably, a fixing rod is provided on the upper end face of the movable block, a limit frame is fixed at the position with the larger inner diameter of the water pumping pipe, and a hole is provided at the center of the limit frame, and the fixing rod passes through the hole at the center of the limit frame after it is raised.

[0012] Preferably, the upper end of the movable tube is connected to the output shaft of the second motor through a pulley mechanism, and the second motor is installed on the upper end face of the protective box. A sleeve block is rotatably sleeved on the outer side of the movable tube, and a fixing hole is reserved on the movable tube inside the sleeve block.

[0013] Preferably, the sleeve block is interconnected with the interior of the movable tube through the fixing hole, and the side of the sleeve block is fixedly connected to one end of the fixing tube, and the other end of the fixing tube is fixed to the output end of the fan. At the same time, the fan is installed on the upper surface of the protective box, and the fixing tube and the sleeve block are connected. A one-way valve is provided inside the fixing tube.

[0014] A detection method for a nearshore ecological early warning water quality pollution detector, the detection method comprising the following steps: First, the device is floated at a designated nearshore location via the first and second float plates. Then, the detector operates, drawing seawater into the movable pipe through the pumping pipe, and then into the detector for testing. During the testing process, the movable tube is driven to rotate by the second motor, which in turn drives the connecting plate to rotate, so that the movable tube can be connected to the pumping pipe at different angles, thus enabling the extraction and testing of seawater at different depths. After the final test is completed, the blower generates gas that is blown into the water pipes at different angles to expel any remaining seawater and empty the pipes, thus preventing any impact on the accuracy of the next test.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The nearshore ecological early warning water quality pollution detector and its detection method are equipped with an auxiliary floating structure, which can increase the contact area between the floating structure and the sea surface when the waves are large, thereby improving the stability of the device. Furthermore, after each sampling test, the seawater in the sampling structure can be drained to avoid residue affecting the accuracy of the next test. The specific details are as follows: 1. Through the meshing transmission of gears and racks, the racks and the second floats, which are distributed at equal angles, are driven to move away from each other. In this way, the distance between the second floats and the first floats can be increased, thereby increasing the contact area with the sea surface, which can improve the overall stability of the device and reduce swaying. 2. The movable tube drives the connecting plate to rotate. When the inlet hole coincides with the connecting hole, the detector can pump seawater through the corresponding pumping pipe for testing. After the seawater at one location is tested, the movable tube continues to drive the connecting plate to rotate, thereby causing the inlet hole to coincide with the connecting hole at different locations. Therefore, it can extract and test seawater at different depths. 3. The gas generated by the blower is transmitted to the sleeve block through the fixed pipe, and then to the movable pipe through the fixed hole. After that, it can enter the water pumping pipe through the liquid inlet hole and the connecting hole, and push the movable block down, squeezing the seawater in the water pumping pipe to discharge it. The rotation of the connecting plate empties the water pumping pipe at different angles so that there is no seawater residue in the next test. Attached Figure Description

Detailed Implementation

[0018] 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.

[0019] Please see Figures 1-9 The present invention provides the following technical solution: Example 1: To address the problems existing in the prior art, this example provides the following technical solution: a nearshore ecological early warning water quality pollution detector, comprising a first float 1, a first motor 2 installed inside the first float 1, and the output shaft of the first motor 2 being connected to a second float 6 via an adjustment mechanism, the second float 6 being equidistantly positioned on the side of the first float 1, and the adjustment mechanism being used to adjust the distance between the second float 6 and the first float 1; further comprising: a protective box 7, fixed to the upper surface of the first float 1, the protective box 7 containing a detection mechanism, and the detection mechanism performing water quality testing by drawing seawater at different depths.

[0020] Because the water pollution detector 17 is used in nearshore areas, the waves are often large. However, the traditional water pollution detector 17 only has a single floating structure and cannot adjust the contact area between the floating structure and the sea surface according to the size of the waves, resulting in poor stability. Figures 1-4 As shown, the adjustment mechanism includes two gears 3 fixed to the output shaft of the first motor 2, and each gear 3 has two racks 4 meshing with its sides. The ends of the racks 4 are fixedly connected to one end of a connecting rod 5. The connecting rod 5 slides through the side of the first float 1, and the other end of the connecting rod 5 is fixed to the second float 6. The second float 6 is hollow, and the two relatively distributed second floats 6 move in opposite directions. First, the device is placed in a designated near-shore location. The first float 1 and the second float 6 float on the sea surface to maintain the device's stability. When there are large waves, the first float 1 is subjected to significant impact and swaying, thus driving the first motor 2 to rotate the two gears 3. Then, through the meshing transmission between the gears 3 and the racks 4, the equally angled racks 4 are driven away from each other, and the connecting rod 5 pushes the second floats 6 away from each other. This increases the distance between the second floats 6 and the first float 1, thereby increasing the contact area with the sea surface, improving the overall stability of the device, reducing swaying, and minimizing the impact on subsequent detection.

[0021] Example 2: In existing water pollution detectors 17, the sampling structure is always submerged in seawater when extracting seawater at different depths. Therefore, residues from previous extractions remain with each extraction, affecting detection accuracy. Furthermore, there is a lack of a structure to vent the interior of the sampling structure after detection. Therefore, this example addresses this issue through the following technical solution: Figures 5-9As shown, the detection mechanism includes a detector 17 installed on the upper surface of the protective box 7. The bottom of the detector 17 is connected to one end of the movable tube 9, and a connecting plate 10 is fixed to the other end of the movable tube 9. An inlet hole 11 is provided at the edge of the connecting plate 10. The lower end face of the connecting plate 10 is in contact with and rotates against the upper end face of the first float 1. A connecting hole 12 is pre-drilled at equal angles on the upper end face of the first float 1. The connecting hole 12 is connected to the movable tube 9 through the inlet hole 11 and is also connected to the water pumping pipe 13. The water pumping pipe 13 is fixedly inserted through the interior of the first float 1. The inner diameter of the middle section of the water pumping pipe 13 is larger than the inner diameters of its two ends. The water pumping pipes 13 are distributed at equal angles, and adjacent water pumping pipes 13 have different lengths. A movable block 14 is slidably attached to the interior of the water pumping pipe 13. The upper end face of the movable block 14 is provided with… A fixed rod 15 is provided, and a limit frame 16 is fixed at the position with the larger inner diameter of the water pumping pipe 13. A hole is provided at the center of the limit frame 16, and the fixed rod 15 passes through the hole at the center of the limit frame 16 after being raised. The upper end of the movable pipe 9 is connected to the output shaft of the second motor 8 through a pulley mechanism. The second motor 8 is installed on the upper end face of the protective box 7. A sleeve block 20 is rotatably sleeved on the outer side of the movable pipe 9. A fixing hole 21 is reserved on the movable pipe 9 on the inner side of the sleeve block 20. The sleeve block 20 is interconnected with the interior of the movable pipe 9 through the fixing hole 21. The side of the sleeve block 20 is fixedly connected to one end of the fixed pipe 19, and the other end of the fixed pipe 19 is fixed to the output end of the fan 18. The fan 18 is installed on the upper end face of the protective box 7. The fixed pipe 19 and the sleeve block 20 are connected. A one-way valve is provided inside the fixed pipe 19.When seawater testing is required, the second motor 8 drives the movable tube 9 to rotate via a pulley mechanism. The movable tube 9 then drives the connecting plate 10 to rotate. When the inlet hole 11 coincides with the connecting hole 12, the detector 17 operates, drawing seawater into the movable tube 9 through the corresponding pumping pipe 13. The seawater then enters the detector 17 for testing. After testing seawater at one location, the movable tube 9 continues to drive the connecting plate 10 to rotate, causing the inlet hole 11 to coincide with the connecting hole 12 at different locations. The corresponding pumping pipe 13 then begins pumping water. Since multiple pumping pipes 13 of different lengths are provided, seawater at different depths can be extracted and tested. After testing is completed, the blower 18 operates to generate gas. The gas is transmitted through the fixed pipe 19 to the sleeve block 20, and then through the fixed hole 21 to the movable tube. The water enters the pumping pipe 13 through the inlet hole 11 and the connecting hole 12, pushing the upper movable block 14 down. During this descent, the movable block 14 squeezes the seawater in the pumping pipe 13, causing it to be expelled. Thus, the pumping pipe 13 is emptied, and the detector 17 is closed, preventing gas leakage. The connecting plate 10 rotates to empty the pumping pipes 13 at different angles, ensuring no seawater residue remains for the next test. Because the fixed pipe 19 has a one-way valve, it can only supply gas to the movable pipe 9. When testing is needed, the detector 17 pumps water, causing the movable block 14 to rise and the fixed rod 15 to pass through the limiting frame 16. The movable block 14 is then blocked by the limiting frame 16 and no longer rises, without affecting the water flow.

[0022] Example 3: A detection method for a nearshore ecological early warning water quality pollution detector, the detection method comprising the following steps: First, the device is floated at a designated nearshore location using the first float plate 1 and the second float plate 6. Then, the detector 17 operates, drawing seawater through the pumping pipe 13 into the movable pipe 9, which then enters the detector 17 for testing. During the testing process, the second motor 8 drives the movable pipe 9 to rotate, which in turn drives the connecting plate 10 to rotate, connecting the movable pipe 9 to the pumping pipes 13 at different angles. This allows for the extraction and testing of seawater at different depths. Finally, after the testing is completed, the blower 18 generates gas and blows it into the pumping pipes 13 at different angles to expel any remaining seawater, ensuring that the pumping pipes 13 are empty and preventing any impact on the accuracy of the next test.
