Description

Technical Field

[0001] This invention relates to the field of water quality testing technology, and in particular to a cruise-type water quality testing device. Background Technology

[0002] With increasingly stringent requirements for water quality, it is essential to scientifically monitor and manage the water environment of river basins and assess and protect aquatic ecosystems. However, traditional water quality testing devices are fixed-location devices, which cannot comprehensively and efficiently detect the overall water quality. Therefore, a cruise-type water quality testing device is needed.

[0003] Current cruise-type water quality monitoring devices often require continuous cruising at different locations to monitor water quality during the monitoring process. However, when conducting monitoring in lakes, they frequently encounter varying water depths. Sudden changes in water depth can easily cause the cruise device to capsize due to instability in its draft, hindering monitoring operations, damaging components, and making recovery difficult. Therefore, this application proposes a cruise-type water quality monitoring device. Summary of the Invention

Four springs are fixedly connected between the bottom of the pressure plate and the water tank. A sealing ring is fixedly connected to the bottom of the water tank and inside the inner hull. The push rod and the sealing ring are slidably connected. A water pipe that penetrates the inner hull and is connected to the double-suction pump is fixedly connected to the inside of the inner hull.

[0012] Preferably, the rotating assembly includes a double-headed toothed plate fixedly connected to the bottom of the push rod and slidably connected to the inner hull. Two reciprocating screws are rotatably connected inside the second inner compartment. A first gear is fixedly connected to each of the two reciprocating screws. A first toothed plate is threaded onto one of the reciprocating screws, and a second toothed plate is threaded onto the other. A first threaded rod is rotatably connected inside the second inner compartment. A second threaded rod is rotatably connected to the side of the second inner compartment closest to the first threaded rod. A second gear is fixedly connected to the top of the first threaded rod, and a third gear is fixedly connected to the second threaded rod. Scraping components for protecting and cleaning the testing equipment are provided on the first and second threaded rods.

[0013] Preferably, the scraping assembly includes a protective shell fixedly connected to the bottom of the inner hull, a filter screen is provided on the protective shell, a cleaning ring blade threadedly connected to a first threaded rod is slidably sleeved on the outer side of the protective shell, a water quality analyzer fixedly connected to the inner hull is provided inside the protective shell, and a cleaning ring sleeve threadedly connected to a second threaded rod is slidably sleeved on the outer side of the water quality analyzer and located inside the protective shell.

[0014] Preferably, a nut is threaded onto the fourth threaded rod, another nut is slidably fitted onto the guide rod, a rotating shaft is rotatably connected to the inside of the inner hull near the fourth threaded rod, an annular groove is formed on the rotating shaft, a blade is fixedly connected to the bottom of the rotating shaft, a fixing block is fixedly connected between the two nuts and slidably connected to the rotating shaft, a locking block is fixedly connected to the inner wall of the fixing block and inside the annular groove, an electric cutter is fixedly connected to the bottom of both nuts, and a motor with a drive end fixedly connected to the fourth threaded rod is fixedly installed inside the inner hull near the top of the fourth threaded rod.

[0015] Preferably, an airbag is fixedly connected to the outer side of the outer hull, an inspection port is provided on one side of the top of the outer hull, several antennas are fixedly connected to the side of the top of the outer hull near the inspection port, a camera is fixedly connected to one side of the top of the inner hull, an electric propeller is provided on the side of the inner hull away from the outer hull, a depth sensor is fixedly connected to the side of the bottom of the inner hull near the water pipe, and a sonar detector is fixedly connected to the side of the inner hull near the electric cutter.

[0017] The present invention has the following beneficial effects:

[0018] 1.

This prevents the aquatic plants from getting tangled on the hull and affecting normal navigation and testing work, ensuring the smooth movement of the device in the water and ensuring that subsequent water quality testing and other tasks can be carried out continuously and stably.

[0019] 2. By incorporating a water pressure component, a dual-suction pump can be used to pump and drain water from the outside environment. The amount of water in the tank can be adjusted according to actual conditions, thereby controlling the overall weight of the device. For example, when the device needs to float or sink, the weight can be adjusted to better adapt to different water depths for water quality testing, improving the device's adaptability and flexibility in various aquatic environments.

[0020] 3. By setting up a rotating component and a scraping component, the rotating component, with its double-headed toothed plate and reciprocating screw working together, can drive the cleaning ring blade and cleaning ring sleeve in the scraping component to move, effectively protecting the water quality analyzer and other testing equipment inside the protective shell, preventing external impurities from damaging the equipment, and cleaning it at the same time, keeping the testing equipment in good working condition, which is conducive to improving the accuracy of the test data and extending the service life of the testing equipment.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Example

[0032] Reference Figures 1-9 A cruise-type water quality monitoring device includes: a hull assembly, a water pressure assembly, and a grass-cutting assembly;

[0033] The hull assembly is used for the basic construction and cruising of the overall detection device, including the outer hull 1 and the inner hull 2 ​​which is fixedly connected inside the outer hull 1;

[0034] The inner hull 2 ​​has a first inner compartment 8 and a second inner compartment 18. The second inner compartment 18 is equipped with a rotating component for synchronous reversal.

[0035] The water pressure assembly is used to control the weight of the overall device by pumping water from the outside. The water pressure assembly includes a water tank 9 fixedly connected inside the first inner compartment 8 and a double suction pump 16 fixedly connected inside the inner hull 2 ​​and located above the first inner compartment 8.

[0036] The mowing assembly is used to cut the aquatic plants encountered by the hull during the cruise to prevent them from getting tangled. The mowing assembly includes a fourth threaded rod 33 that is rotatably connected to the inside of the outer hull 1 and a guide rod 34 that is fixedly connected to the inside of the outer hull 1.

[0037] Additionally, a nut 35 is threaded onto the fourth threaded rod 33, and another nut 35 is slidably fitted onto the guide rod 34. A rotating shaft 36 is rotatably connected to the side of the inner hull 2 ​​near the fourth threaded rod 33. An annular groove 37 is provided on the rotating shaft 36. A blade 38 is fixedly connected to the bottom of the rotating shaft 36. A fixing block 39 is fixedly connected between the two nuts 35 and slidably connected to the rotating shaft. A locking block 40 is fixedly connected to the inner wall of the fixing block 39 and inside the annular groove 37. An electric cutter 41 is fixedly connected to the bottom of both nuts 35. A motor 42 is fixedly installed above the fourth threaded rod 33 inside the inner hull 2.

[0038] In this embodiment, after the sonar detector 43 detects water plants in front of the hull, the motor 42 is activated. The motor 4 drives the third threaded rod 33 to rotate. At this time, the nut 35 on the third threaded rod 33 can slide downward along the guide rod 34 to the bottom of the hull. Then, the electric cutter 41 is activated to cut the water plants, which can efficiently cut the water plants encountered during the cruise. Whether it is a thin filamentous water plant or a dense clump of water plants, it can be dealt with in time to prevent it from getting tangled on the propeller or other critical parts of the hull. This ensures that the device can maintain a stable sailing speed and course, and avoids problems such as power obstruction and control failure due to water plants getting tangled.

[0039] At the same time, the two nuts 35 slide down, causing the fixing block 39 to slide along the rotating shaft 36. At this time, the rotating shaft 36 can continuously rotate along the locking block 40 on the inner wall of the fixing block 39 through the annular groove 37 on it. The rotating shaft 36 can drive the blade 38 to rotate, thereby further cutting and cleaning the water plants wrapped on the nuts 35.

[0040] Furthermore, without effective weed control measures, tangled weeds often require manual removal, which not only consumes a significant amount of manpower and time, but also poses a risk of damage to the ship's structure and related equipment due to frequent cleaning operations, increasing additional maintenance costs. The weed-cutting component of this device can automatically handle weed problems during navigation, greatly reducing the frequency of manual intervention and lowering various maintenance costs caused by weed entanglement. It also saves considerable time that would otherwise be devoted to maintenance, allowing the device to focus more on actual water quality testing. Example

[0041] Reference Figures 2-6 Compared to Embodiment 1, in this embodiment, the top of the water tank 9 is fixedly connected to a folded hose 10 that communicates with the double suction pump 16. The bottom of the folded hose 10 is fixedly connected to a water inlet 11. The bottom of the water inlet 11 is fixedly connected to a pressure plate 12. The bottom of the pressure plate 12 is fixedly connected to a push rod 13 that is slidably connected to the water tank 9. The bottom of the pressure plate 12 is fixedly connected to the water tank 9. The bottom of the water tank 9 and inside the inner hull 2 ​​is fixedly connected to a sealing ring 15. The push rod 13 and the sealing ring 15 are slidably connected. The inner hull 2 ​​is fixedly connected to a water pipe 17 that passes through the inner hull 2 ​​and communicates with the double suction pump.

[0042] The rotating assembly includes a double-headed toothed plate 21 fixedly connected to the bottom of the push rod 13 and slidably connected to the inner hull 2. The interior of the second inner compartment 18 is rotatably connected to two reciprocating screws 19, each of which is fixedly connected to a first gear 20. One reciprocating screw 19 is threaded with a first toothed plate 22, and the other reciprocating screw 19 is threaded with a second toothed plate 23. The interior of the second inner compartment 18 is rotatably connected to a first threaded rod 24. The interior of the second inner compartment 18 is rotatably connected to a second threaded rod 25 on the side near the first threaded rod 24. The top of the first threaded rod 24 is fixedly connected to a second gear 26, and the second threaded rod 25 is fixedly connected to a third gear 27.

[0043] The scraping assembly includes a protective shell 30 fixedly connected to the bottom of the inner hull 2. A filter screen 31 is provided on the protective shell 30. A cleaning ring blade 28 that is threadedly connected to the first threaded rod 24 is slidably sleeved on the outer side of the protective shell 30. A water quality detector 32 that is fixedly connected to the inner hull 2 ​​is provided inside the protective shell 30. A cleaning ring sleeve 29 that is threadedly connected to the second threaded rod 25 is slidably sleeved on the outer side of the water quality detector 32 and inside the protective shell 30.

[0044] In this embodiment, the depth sensor 43 detects different water depths. Then, the dual-suction pump 16 pumps water into the water tank 9 through the water pipe 17. The water flows into the water tank 9 through the inlet 11 at the bottom of the folded hose 10. The more water in the tank 9, the more it compresses the pressure plate 12, pushing the push rod 13 downwards, allowing the device to flexibly adjust its weight according to actual testing needs. When it needs to delve into deeper waters for water quality sampling and testing, the dual-suction pump can pump water from outside into the tank, increasing the overall weight of the device and improving the overall stability of the vessel. After completing the testing task at that depth and reaching shallower water, the dual-suction pump can drain the water from the tank, reducing the weight of the device and allowing it to float to a suitable position to prevent it from running aground. This flexible weight adjustment feature greatly expands the range of water depths the device can operate in, enabling it to comprehensively cover water quality testing from shallow to deep water areas, obtaining more comprehensive and accurate water quality data.

[0045] Furthermore, when the dual-suction pump 16 pumps water into the water tank 9, the pressure plate 12 pushes the push rod 13 downwards. The push rod 13 drives the double-headed toothed plate 21 to slide, and the double-headed toothed plate 21 drives the two first gears 20 to rotate synchronously in opposite directions. This drives the two reciprocating screws 19 to rotate, which in turn drives the first toothed plate 22 and the second toothed plate 23 on them to move, thereby dragging the second gear 26 and the third gear 27 to rotate. At this time, the first threaded rod 24 and the second threaded rod 25 rotate synchronously in opposite directions, driving the cleaning ring blade 28 and the cleaning ring sleeve 29 on them to move alternately and reciprocally on and inside the protective shell 30 according to a specific trajectory, thereby cleaning the filter screen 31 and the surface of the water quality analyzer 32. This prevents the filter screen 31 from becoming clogged and affecting the entry of water samples. At the same time, the cleaning ring sleeve 29 cleans the surface of the water quality analyzer 32, ensuring that the analyzer can accurately sense the content of various components, pH, dissolved oxygen and other key indicators in the water sample.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
