Description

Technical Field

[0001] This invention relates to the field of garden water body monitoring technology, specifically to an intelligent water quality monitoring device for garden water bodies. Background Technology

[0002] Garden water features are dynamic or static landscape elements centered around water in garden landscapes, including ponds, streams, fountains, artificial lakes, etc. They not only serve the functions of regulating the ecology and beautifying the environment, but also provide habitats for animals and plants.

[0003] Monitoring garden water bodies is crucial because their water quality is easily affected by factors such as rainfall, visitor activities, surrounding vegetation, and maintenance. If eutrophication leads to algal blooms, decreased dissolved oxygen, or excessive pollutants, it will not only damage the landscape but also threaten the survival of aquatic organisms and even affect the safety of surrounding soil and groundwater through infiltration or runoff.

[0004] Patent application number CN202511323831.7 specifically relates to an intelligent water quality monitoring device for garden water bodies, including a base and a round basin; the round basin is fixed to the base, and a pull ring is installed on the round basin. This invention achieves water quality monitoring by releasing a water pipe, which moves vertically downwards under the gravity of a counterweight ball, creating negative pressure within the pipe. This pressure then allows water samples to be extracted through a filter head, which filters impurities from the water. The water sample flows along the water pipe, round pipe, guide pipe, water pump, and delivery pipe, finally flowing into a collection cylinder through the delivery pipe. A baffle and a guide vane I support the extracted water sample, submerging the monitoring probe. The monitoring probe is then activated to detect the water sample, thus enabling monitoring of water bodies in gardens. This method is short-cycle, highly efficient, and meets real-time requirements.

[0005] This patent controls an external motor to drive a propeller to rotate and move the base, causing the filter ball head to shift in the water, thereby enabling the extraction of water samples from different water areas. However, it has two major drawbacks: first, it detects different depths sequentially, making it difficult to collect samples quickly and continuously; second, storing water samples from different depths together in the same water collection tank can easily lead to cross-contamination and data distortion.

[0006] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Summary of the Invention

[0024] like Figures 1 to 9As shown, the present invention provides an intelligent water quality monitoring device for garden water bodies, comprising: a floating chamber 1, a sampling mechanism 2 disposed within the floating chamber 1, and a driving mechanism 3 for moving the floating chamber 1; The sampling mechanism 2 consists of a collection component 21 and a liquid aspiration component 22; The collection assembly 21 includes: a rotating frame 211 rotatably installed in the floating chamber 1, a collection bucket 212 equidistantly placed on the rotating frame 211, a fixing assembly 213 fixing the collection bucket 212, a nozzle 214 fixedly installed in the floating chamber 1, and a rotating assembly that drives the rotating frame 211 to rotate. The liquid suction assembly 22 includes: a support frame 221 fixedly installed in the floating chamber 1, a winding roller 222 rotatably installed on the support frame 221, a steel cable 223 wound on the winding roller 222, a sinking chamber 224 fixedly installed at one end of the steel cable 223, and a water inlet 225 provided in the sinking chamber 224. The water inlet 225 is connected to the nozzle 214 through a hose 226.

[0025] The floating chamber 1 is basin-shaped; an airbag 11 is fixedly installed along the side wall of the floating chamber 1.

[0026] The rotating assembly includes: a motor fixedly installed in the floating chamber 1, a rotating rod 2152 fixedly connected to the output shaft of the motor, a bevel gear 2153 coaxially fixedly installed on the rotating rod 2152, and a bevel ring 2154 fixedly installed on the rotating frame 211, wherein the bevel ring 2154 meshes with the bevel gear 2153.

[0027] When water quality sampling and testing are required in garden water bodies, staff will move the entire testing equipment and place it on the surface of the garden lake. Thanks to the unique structural mechanics of the floating chamber 1 and the stable buoyancy generated by the built-in airbag 11, the floating chamber 1 can float stably on the water surface. Subsequently, with the power output provided by the built-in drive mechanism 3, the floating chamber 1 will autonomously navigate and move across the water surface. This ensures that the testing equipment can reach water areas that are difficult for staff to access due to geographical limitations, thereby achieving more comprehensive and thorough water quality sampling. This significantly improves the practical effectiveness and applicability of the testing device in garden water quality monitoring scenarios.

[0028] When the floating chamber 1 is precisely moved and positioned directly above the target water area to be detected, the drive motor starts running, and its output shaft transmits rotational power to the gear transmission system. Under the precise meshing transmission of the gear pair, the drive rotating frame 211 rotates uniformly around its own axis inside the floating chamber 1.

[0029] At this time, several collection buckets 212, fixedly installed on the rotating frame 211, rotate synchronously with the rotating frame 211. As the rotating frame 211 continues to rotate, each collection bucket 212 moves sequentially to a designated position directly below the nozzle 214 according to a preset trajectory. The nozzle 214 sprays water samples at fixed times and in fixed quantities according to a predetermined program, allowing the collection buckets 212 to continuously collect multiple independent water sample samples.

[0030] This design allows for simultaneous testing of multiple water samples, effectively shortening the overall testing process and improving efficiency. Furthermore, using multiple independent collection containers 212 to store different water samples effectively avoids mixing samples from different sources, preventing cross-contamination and ensuring the accuracy and reliability of the test results.

[0031] When sampling water at different depths in a garden's water features, the control system of the winding roller 222 precisely calculates and releases a steel cable 223 of corresponding length based on pre-set target sampling depth parameters. During the smooth release of the steel cable 223 by the winding roller 222, the sinking chamber 224, due to its own gravity, overcomes the buoyancy and resistance of the water, moving vertically downwards at a uniform speed along the traction direction of the steel cable 223. As the sinking chamber 224 descends, it simultaneously moves the inlet 225 at its bottom downwards until the inlet 225 precisely reaches the preset depth. At this point, the valve at the inlet 225 opens, and water flows into the sinking chamber 224 under pressure difference, thus achieving precise extraction of water samples from different depths and providing reliable samples for subsequent comprehensive and accurate water quality analysis.

[0032] A first synchronous roller 2155 is coaxially fixedly installed on one side of the winding roller 222; a second synchronous roller 2156 is coaxially fixedly installed on the rotating rod 2152; a synchronous belt 2157 is provided on the first synchronous roller 2155 and the second synchronous rod.

[0033] It is important to emphasize that when the motor rotates, it drives the rotating frame 211 to rotate along the floating chamber 1, while the winding roller 222 rotates synchronously on the support frame 221. On the one hand, as the rotating frame 211 rotates, the collection bucket 212 fixedly installed on it moves along a predetermined trajectory and is precisely positioned directly below the nozzle 214, thereby orderly receiving the water sample sprayed from the nozzle 214. On the other hand, during the rotation of the winding roller 222, it releases a steel cable 223 of a corresponding length according to the preset transmission ratio, so that the sinking chamber 224 connected to the end of the steel cable 223 descends at a uniform speed in the vertical direction to the designated water sample collection depth position under its own gravity.

[0034] For example, when staff set the water sample collection depth to 2 meters, the motor operates according to a pre-programmed number of rotations. Simultaneously, while driving the first collection bucket 212 to accurately move to the designated receiving position below the nozzle 214, the winding roller 222 rotates the corresponding number of times, precisely controlling the release length of the steel cable 223 to ensure the sinking chamber 224 is lowered to a depth of 2 meters for water sample collection. Through this design, each collection bucket 212 corresponds to a specific depth of water sample, effectively avoiding cross-contamination between samples from different depths and ensuring the independence and accuracy of water sample collection.

[0035] Furthermore, to further enhance the ease of operation and practicality of the device, each collection bucket 212 is engraved with a clear and unique number. When selecting water samples from specific depths for individual testing, staff can quickly and accurately identify the target water sample by observing the number on the collection bucket 212, without the need for additional complex identification procedures. This significantly improves the practical effectiveness and operational efficiency of the entire water quality sampling and testing device.

[0036] The fixing component 213 includes: a sliding groove formed on the rotating frame 211, and an arc-shaped clamping plate 1 2132 and an arc-shaped clamping plate 2133 slidably installed in the sliding groove; the arc-shaped clamping plate 1 2132 and the arc-shaped clamping plate 2133 are mirror images of each other; a movable pin 2134 is inserted between the arc-shaped clamping plate 1 2132 and the arc-shaped clamping plate 2133; the movable pin 2134 is elastically connected to the arc-shaped clamping plate 1 2132 and the arc-shaped clamping plate 2133 on both sides by a spring 1 2135; the arc-shaped clamping plate 1 2132 and the arc-shaped clamping plate 2133 are elastically connected to the rotating frame 211 by a spring 2136.

[0037] When the collection bucket 212 needs to be placed or removed, the operator only needs to manually apply force to pry open the first arc-shaped clamp 2132 and the second arc-shaped clamp 2133 along their connecting axis, creating an opening space large enough to accommodate the collection bucket 212. Then, the collection bucket 212 is precisely placed within the clamping area formed by the first arc-shaped clamp 2132 and the second arc-shaped clamp 2133. At this point, the built-in high-elasticity spring, with its excellent elastic deformation characteristics, generates a stable and continuous clamping force, firmly clamping the collection bucket 212 between the arc-shaped clamps.

[0038] This fixing method, based on the principle of spring elastic clamping, effectively ensures that the collection bucket 212 remains highly stable and stationary during complex movements such as high-speed or variable-speed rotation of the rotating frame 211. This prevents water sample spillage or leakage caused by shaking, thus guaranteeing the integrity and accuracy of water sample collection. Furthermore, this fixing method is simple and quick to operate, requiring no additional tools or complex procedures, significantly improving the efficiency and convenience of placing and removing the collection bucket 212.

[0039] The sinking chamber 224 is equipped with a water supply system; The water supply assembly includes: a cavity 22411 opened in the sinking chamber 224, a mounting frame 22412 rotatably installed in the cavity 22411, a motor 22413 that drives the mounting frame 22412 to rotate, a squeezing roller 22414 rotatably installed on the mounting frame 22412, a hose 226 laid on the inner wall of the sinking chamber 224, and the squeezing roller 22414 and the hose 226.

[0040] Once the sinking chamber 224 is pulled down to the preset target depth by the help of the winding roller 222 and remains stable, the drive motor 22413 starts to operate. The output shaft of the drive motor 22413 transmits the rotational power to the mounting frame 22412 through a coupling and other transmission components, driving the mounting frame 22412 to rotate directionally around its central axis inside the sinking chamber 224.

[0041] During the rotation of the mounting frame 22412, the compression roller 22414 mounted on it rotates synchronously. As it rotates, the compression roller 22414 continuously contacts and applies a regular compressive force to the hose 226 pre-arranged within the sinking chamber 224. With the continuous rotation of the compression roller 22414, the hose 226 is periodically compressed and deformed, creating a dynamically changing negative pressure environment inside the hose 226.

[0042] Because one end of the flexible hose 226 is tightly connected to the inlet 225 located on the side wall or bottom of the settling chamber 224, under the negative pressure inside the hose 226, lake water at the target depth is drawn into the hose 226 through the inlet 225 under atmospheric pressure. After entering the hose 226, the lake water is transported along the fluid channel formed on the inner wall of the hose 226 to the nozzle 214 connected to the other end of the hose 226. The nozzle 214 sprays the lake water at a specific flow rate and volume into the pre-positioned collection bucket 212 according to preset spray parameters, thereby achieving precise collection and transfer of water samples at different depths.

[0043] The bottom of the sinking chamber 224 is also equipped with a crushing component 2242; The crushing assembly 2242 includes: a shaft 22421 rotatably mounted on the bottom of the sinking chamber 224, a hinge rod 22422 fixedly mounted on the shaft 22421, a crushing blade 22423 hinged to the hinge rod 22422, and an adjusting assembly 22424 for adjusting the angle of the crushing blade 22423; the shaft 22421 is fixedly connected to the output shaft of the second motor 22413.

[0044] Given that most garden water bodies are stagnant, with very little water flow, they are highly susceptible to the growth of aquatic plants and various suspended impurities. The presence of these plants and impurities significantly interferes with the water extraction process, reducing sampling efficiency and quality.

[0045] When drive motor 22413 starts operating, it drives shaft 22421 to rotate. During rotation, shaft 22421 transmits power to the breaker blade 22423 mounted on it, driving the breaker blade 22423 to rotate at high speed around the central axis of shaft 22421. With its sharp cutting edge and rational structural design, breaker blade 22423 forms a highly efficient cutting zone in the water below the sinkhole 224, mechanically shredding the aquatic plants growing there.

[0046] The crushing action of the crushing blade 22423 effectively prevents aquatic plants from tangling and adhering to the outer surface of the sinking chamber 224, avoiding problems such as increased resistance and obstructed movement when the sinking chamber 224 is lowered or raised due to tangling. On the other hand, it significantly reduces the risk of the inlet 225 being blocked by aquatic plants and large particles, ensuring smooth water flow at the inlet 225, guaranteeing the continuity and stability of the water extraction process, and thus improving the reliability and applicability of the entire water sampling device in complex water environments.

[0047] It should be explained in detail here that when motor 22413 rotates, on the one hand, it drives the mounting bracket 22412 to rotate, continuously squeezing the hose 226 to draw water into the collection bucket 212; on the other hand, it drives the breaker blade 22423 to rotate and cut the aquatic plants below the sinking chamber 224, preventing the aquatic plants from getting tangled on the outside of the breaker chamber and affecting the sinking of the sinking chamber 224.

[0048] The adjusting assembly 22424 includes: an inner rod 224241 sleeved on the shaft 22421, a support rod 224242 hinged to the inner rod 224241, and the other end of the support rod 224242 hinged to the crusher 22423; the top end of the inner rod 224241 is elastically connected to the inner wall of the shaft 22421 by a spring 224243.

[0049] As the sinking chamber 224 continues to descend and gradually approaches the riverbed bottom, the inner rod 224241 at its bottom will be the first to contact the riverbed surface. Under the pressure of the riverbed's reaction force, the inner rod 224241 slides inward along the pre-set guide groove inside the shaft 22421, applying axial pressure to the compression spring nested inside the shaft 22421, causing it to undergo elastic deformation. As the inner rod 224241 displaces along the axial direction of the shaft 22421, the support rod 224242, hinged to the inner rod 224241 via a linkage mechanism, generates a lever effect, pushing the breaker blade 22423 assembly to expand outward around its rotation axis until the cutting edge plane of the breaker blade 22423 becomes parallel to the axial centerline of the inner rod 224241.

[0050] It should be noted that, to optimize the cutting efficiency of aquatic plants and the water flow guidance effect, the breaker blade 22423 assembly adopts a variable angle structure design: In the normal working state where the inner rod 224241 is not under pressure, the cutting edge of the breaker blade 22423 is arranged at a 45° angle to the axis of the shaft 22421. At this time, the rotation of the breaker blade 22423 creates a propeller effect, and its cutting edge can efficiently cut and break up aquatic plants and suspended impurities in the water, while also guiding the water flow into the inlet 225 in an orderly manner through the spiral flow field, improving the efficiency of water sample collection. When the inner rod 224241 touches the bottom and is under pressure, driving the breaker blade 22423 to expand to a state parallel to the inner rod 224241, the axial force of the breaker blade 22423 during rotation is significantly reduced, effectively reducing the mechanical disturbance intensity of the rotating blade assembly to the riverbed sediments. Fluid dynamics simulations have verified that this design can reduce the resuspension rate of sediment after contact with the bottom by more than 70%, thereby avoiding excessive turbidity in collected water samples due to the entrainment of large amounts of riverbed sediment, and ensuring the accuracy and reliability of subsequent water quality testing and analysis results.

[0051] It should be further explained that a proximity switch is provided on the inner rod 224241, and a sensing element matching the proximity switch on the shaft 22421 is provided on the shaft 22421. When the inner rod 224241 reaches the bottom and performs an upward displacement operation, the proximity switch on the inner rod 224241 and the sensing element on the shaft 22421 gradually approach each other. After reaching the set sensing distance, the proximity switch is triggered, which in turn transmits an electrical signal to the control terminal. Upon receiving the electrical signal, the control terminal immediately issues a command to stop the motor, thereby ensuring that the sinking chamber 224 does not completely touch the bottom and preventing the inlet 225 from sucking in sludge from the riverbed surface, thus improving the accuracy of water quality sampling.

[0052] In summary, when the sink 224 approaches the bottom, the inner rod 224241 first touches the bottom and then moves upward. During this process, on the one hand, the motor stops rotating through the cooperation of the aforementioned proximity switch and sensing element; on the other hand, the tilt angle of the crushing blade 22423 is adjusted synchronously to reduce its agitation of the riverbed sludge, thereby improving the cleanliness of the water sample.

[0053] The drive mechanism 3 includes: a motor 31 fixedly installed on the floating tank 1, and a spiral blade 32 fixedly installed on the motor 31.

[0054] When it is necessary to move the floating chamber 1 on the water surface, simply drive motor 31 to rotate. Motor 31 drives the spiral blade 32 to rotate, and the rotation of the spiral blade 32 propels the floating chamber 1 to move.

[0055] The floating chamber 1 is equipped with a top cover 12; by setting the top cover 12, a closed environment can be effectively constructed to prevent external pollutants from entering, ensure the purity of the sample in the collection bucket 212 after sampling, and avoid the sample being affected by external factors, thus affecting the accuracy of the test results.
