Description

Technical Field

[0001] This utility model belongs to the technical field of spraying devices, and more specifically, it relates to a floating water quality monitoring device. Background Technology

[0002] Water quality monitoring devices are equipment used to detect various physicochemical indicators in water bodies in real time. They can effectively monitor key parameters such as pH and dissolved oxygen in water bodies. Water quality monitoring devices come in various types, and the appropriate type can be selected according to the usage environment. Floating water quality monitoring devices are one type of water quality monitoring device.

[0003] This type of monitoring device, through its floating structure and stable anchoring system, can float on the water surface and adapt to the complex environment of open water. However, traditional water quality monitoring devices mostly rely on fixed-shape floats for buoyancy and cannot dynamically adjust their buoyancy and center of gravity according to water fluctuations. This makes them prone to tilting and overturning under water flow impacts or severe weather, causing the monitoring probe to deviate from its effective position and significantly reducing data accuracy. At the same time, traditional devices cannot simultaneously detect water layers at different depths, making it difficult to obtain complete water quality profile data and failing to meet the multi-dimensional monitoring needs in complex water environments. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a floating water quality monitoring device to solve the technical issues of existing devices having unadjustable buoyancy, being prone to shaking leading to inaccurate data, and being unable to perform simultaneous monitoring at multiple depths.

[0005] The purpose and effectiveness of this floating water quality monitoring device are achieved through the following specific technical means:

[0006] A floating water quality monitoring device includes a main shell and a top cover covering the main shell. The main shell and the top cover are connected to form a main cavity. An adjustment component and a monitoring component are disposed in the main cavity.

[0007] The adjustment component includes an airbag, and multiple sets of floating boxes are arranged around the periphery of the main body shell. The airbag is installed in the floating box, and multiple sets of water inlet pipes are arranged at the bottom of the floating box. The floating box can be in a water-filled state and a water-drained state through the airbag.

[0008] The monitoring component includes multiple sets of monitoring elements and a winch for adjusting the height of the monitoring elements. An inlet and outlet pipe is provided inside the main body shell. The inlet and outlet pipe is through-hole. The winch is installed inside the inlet and outlet pipe and is driven by a motor provided on one side of the inlet and outlet pipe.

[0009] One set of the monitoring components is connected to the winch and is also connected to another set of the monitoring components via a connecting rope.

[0010] The main body cavity is equipped with a controller and a battery. The controller is electrically connected to the battery and a wireless module is installed in the controller.

[0011] According to a preferred embodiment, the adjustment assembly further includes multiple sets of air pumps, and a mounting bracket is provided inside the main body cavity. The multiple sets of air pumps and the controller are all mounted on the mounting bracket. An opening is provided at one end of the floating box, so that the floating box communicates with the main body cavity.

[0012] The floating box has a cover plate at its opening end, and a floating cavity is formed by connecting the cover plate to the floating box. The airbag is located in the floating cavity, and a connecting valve is provided on the airbag. The connecting valve passes through the cover plate, and the air pump is connected to the connecting valves on multiple sets of the airbags through a connecting pipe.

[0013] According to a preferred embodiment, the drainage state is as follows: when the floating box is filled with liquid and the air bladder is in a flat state, the air pump inflates the air bladder, the pressure inside the floating box increases, and the liquid is discharged from the water inlet pipe.

[0014] The water-filled state is when the floating box is not full of liquid, the airbag is inflated, the air pump pumps the airbag to reduce the pressure inside the floating box, and the liquid enters from the water inlet pipe.

[0015] According to a preferred embodiment, the water inlet pipe includes a first sleeve and a second sleeve, wherein the first sleeve is disposed at the bottom of the floating box and communicates with the floating box;

[0016] The first sleeve is fitted with a bearing, and the second sleeve is provided with a connecting sleeve at one end. The second sleeve is inserted into the first sleeve, and the connecting sleeve is fitted on the bearing. The second sleeve is rotatably connected to the first sleeve.

[0017] According to a preferred embodiment, one end of the second sleeve is closed, and multiple sets of water inlet holes are provided in the second sleeve, with an angle α formed between the water inlet holes and the axial diameter of the second sleeve.

[0018] Angle α is between 10° and 30°.

[0019] According to a preferred embodiment, the winch is installed at the top of the inlet / outlet pipe, and a rope is provided on the winch, one end of which is connected to one of the monitoring components;

[0020] The inlet and outlet pipe is equipped with a partition, which divides the inlet and outlet pipe into a lifting area and a component area. Multiple sets of monitoring devices are located in the lifting area, the winch is located in the component area, and the rope is threaded between the component area and the lifting area.

[0021] The bottom of the partition is provided with two sets of connecting frames, and the connecting frames are provided with brushes. The rope is threaded between the two sets of brushes and is in contact with the brushes.

[0022] According to a preferred embodiment, the monitoring component includes a first outer shell and a second outer shell, the first outer shell and the second outer shell are connected to form a spherical mounting part, the mounting part is provided with a detection area and a mounting area, and multiple sets of through grooves are provided on the first outer shell and the second outer shell, the detection area is connected to the outside through the through grooves;

[0023] The installation area is equipped with a water quality sensor and a processing module. The water quality sensor has a probe that passes through the detection area. The processing module is electrically connected to both the water quality sensor and the controller.

[0024] According to a preferred embodiment, multiple sets of monitoring components are arranged in a straight line along the axis, and the multiple sets of monitoring components are connected by the connecting rope. The topmost monitoring component is connected to the rope, and the bottommost monitoring component is connected to a falling block by the connecting rope. The falling block is cone-shaped.

[0025] The bottom of the inlet and outlet pipe is equipped with a protective cover, which is funnel-shaped.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] The air bladder and floating box in the regulating assembly work together to adjust buoyancy and center of gravity in real time according to water fluctuations. When encountering water flow impact, the air pump inflates the air bladder, causing the floating box to be in a deflated state, lowering the center of gravity of the device and significantly improving stability. Conversely, deflating the air bladder fills the floating box with water, increasing the draft to withstand wind and waves. At the same time, the water inlet pipe adopts a double-sleeve rotating structure. The angled water inlet hole on the second sleeve can adjust the water inlet angle according to the water flow direction, avoiding water sample collection deviation caused by water turbulence.

[0028] In the monitoring assembly, the winch, as the core driving component, is installed at the top of the inlet and outlet pipes, powered by a dedicated motor. One end of a high-strength rope wound around its outer side is securely connected to the topmost monitoring element. Multiple monitoring elements are connected in series via axially arranged connecting ropes, with the bottommost monitoring element connected to a conical drop block. This structural design enables multi-level coordinated operation: as the winch rotates and retracts the rope under motor drive, multiple monitoring elements can move synchronously up and down along the lifting and lowering zones within the inlet and outlet pipes. Through preset programs or remote control commands, they can be positioned at different depths, including the surface, middle, and bottom layers of the water.

[0029] The cone-shaped drop block not only straightens the connecting rope under its own weight, ensuring the monitoring components remain vertically distributed, but also effectively reduces the lateral impact of water flow on the device. The component area and lifting area, divided by the baffles inside the inlet and outlet pipes, provide protective space for drive components such as the winch, and ensure the monitoring components are not disturbed during lifting. When multiple monitoring components are stationary at different water layers, the built-in water quality sensors can simultaneously monitor parameters such as pH, dissolved oxygen, and ammonia nitrogen content at each point in real time.

[0039] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model. Example

[0040] like Figures 1 to 7 As shown, this utility model provides a floating water quality monitoring device, including a main shell 11 and a top cover 12 covering the main shell 11. The main shell 11 is made of high-strength corrosion-resistant material, which can resist the erosion of acid and alkali substances in the water and is not easily damaged after long-term use. The top cover 12 is connected to the main shell 11 by means of snaps or threads to form a relatively sealed main cavity. The internal space of the main cavity is rationally planned to accommodate the adjustment components and monitoring components, providing an installation location and protective space for the core components of the entire device.

[0041] The main body shell 11 and the top cover 12 are connected to form a main body cavity, and an adjustment component and a monitoring component are installed inside the main body cavity. The existence of the adjustment component allows the device to adjust its floating state according to the actual use environment; the monitoring component is responsible for detecting various water quality indicators. The two work together to ensure that the device can realize the water quality monitoring function.

[0042] The adjustment assembly includes an airbag 21, and multiple floating boxes 16 are arranged around the main body shell 11. The airbag 21 is made of highly elastic and tensile-resistant rubber material and is installed inside the floating box 16. Multiple water inlet pipes are provided at the bottom of the floating box 16, allowing the floating box 16 to be in a water-filled state and a water-drained state through the airbag 21. When the airbag 21 contracts, the internal space of the floating box 16 increases, and external water enters the floating box 16 through the water inlet pipes under pressure, and the device enters the water-filled state. At this time, the draft increases, which can reduce the swaying amplitude of the device in the case of large waves. When the airbag 21 inflates, it squeezes the water in the floating box 16, and the water is discharged through the water inlet pipes, and the device enters the water-drained state, lowering the center of gravity and enhancing the stability under the impact of water flow.

[0043] The monitoring assembly includes multiple monitoring elements and a winch 31 for adjusting the height of the monitoring elements. An inlet / outlet pipe 13 is installed inside the main housing 11, and the inlet / outlet pipe 13 is through-type. The winch 31 is installed inside the inlet / outlet pipe 13 and is driven by a motor located on one side of the inlet / outlet pipe 13. The winch 31 is rotated by the motor, enabling the raising and lowering of ropes connected to the monitoring elements. Multiple monitoring elements can move up and down along the inlet / outlet pipe 13. This configuration allows the device to detect water quality at different water layers, obtaining more comprehensive water quality information and avoiding the data limitations of only detecting a single fixed water layer.

[0044] One set of monitoring devices is connected to the winch 31 and then to another set of monitoring devices via a connecting rope. Multiple sets of monitoring devices are connected in series by the connecting rope and can be raised and lowered synchronously under the action of the winch 31, ensuring that the monitoring work at different water layers is carried out in an orderly manner. Each monitoring device works together to complete the detection task at different depths of the water body.

[0045] The main body houses a controller 14 and a battery 15, which are electrically connected. The controller 14 also contains a wireless module and can be an STM32F407VGT6 controller. The battery 15 provides power to the entire device; both the operation of the regulating components and the work of the monitoring components rely on its electrical energy. The controller 14, acting as the "brain" of the device, is responsible for controlling and coordinating the operation of each component. It receives data from the monitoring components, performs preliminary data processing, and then transmits the data to a remote terminal via its built-in wireless module, allowing staff to monitor water quality in real time.

[0046] A solar panel and solar charge controller can be added to the top of the device. The solar panel is made of high-conversion-efficiency material and is connected to the controller via waterproof wires. The controller can automatically adjust the charging voltage and current to prevent overcharging and over-discharging, achieving stable solar charging of the battery and improving the device's range.

[0047] like Figure 2 , Figure 4 , Figure 5 As shown, the adjustment assembly also includes multiple air pumps 22, and a mounting bracket 23 is provided inside the main body cavity. The multiple air pumps 22 and the controller 14 are all mounted on the mounting bracket 23. One end of the float box 16 has an opening, allowing the float box 16 to communicate with the main body cavity. The mounting bracket 23 provides a stable mounting position for the air pumps 22 and the controller 14, ensuring that these components will not easily shake or shift during device operation. The air pumps 22 are connected to the air bladder 21 via pipes, enabling them to inflate and deflate the air bladder 21, thereby switching between the water-filled and water-drained states of the float box 16. The design of the float box 16 communicating with the main body cavity forms a complete working system among the air pumps 22, the air bladder 21, and the float box 16.

[0048] A cover plate 24 is provided at the open end of the floatation box 16. A floating cavity is formed by connecting the cover plate 24 to the floatation box 16. An airbag 21 is located within the floating cavity and is equipped with a connecting valve that passes through the cover plate 24. An air pump 22 is connected to the connecting valves on multiple airbags 21 via a connecting pipe. The cover plate 24 closes the opening of the floatation box 16, forming a floating cavity together with the floatation box 16, providing a relatively independent working space for the airbag 21. The connecting valves ensure the flow of gas between the air pump 22 and the airbag 21. The air pump 22 operates the airbag 21 through the connecting pipes and connecting valves, controlling the expansion and contraction of the airbag 21.

[0049] In the drainage state, when the float box 16 is filled with liquid and the air bladder 21 is in a flattened state, the air pump 22 inflates the air bladder 21, increasing the pressure inside the float box 16 and discharging the liquid from the inlet pipe. In the water-filling state, when the float box 16 is not filled with liquid and the air bladder 21 is in an inflated state, the air pump 22 deflates the air bladder 21, decreasing the pressure inside the float box 16 and allowing liquid to enter through the inlet pipe. This switching mechanism between water-filling and drainage states allows for flexible adjustment of the device's buoyancy performance according to changes in the actual aquatic environment. For example, in fast-flowing water, the center of gravity can be lowered in the drainage state to enhance stability; when deeper water data is needed, the draft can be increased in the water-filling state.

[0050] The inlet pipe includes a first sleeve 41 and a second sleeve 42. The first sleeve 41 is located at the bottom of the float box 16 and communicates with it. A bearing is fitted onto the first sleeve 41. A connecting sleeve is provided at one end of the second sleeve 42, which passes through the first sleeve 41. The connecting sleeve is fitted onto the bearing, and the second sleeve 42 is rotatably connected to the first sleeve 41. The first sleeve 41 serves as the fixed part of the inlet pipe, ensuring a stable connection between the inlet pipe and the float box 16, allowing water to smoothly enter the float box 16. The second sleeve 42 is connected to the first sleeve 41 via the bearing and can rotate relative to it. When the water flow direction changes, the second sleeve 42 can rotate under the action of the water flow, adjusting its angle to make the water intake smoother, reduce the impact of the water flow on the inlet pipe, and ensure a stable water intake.

[0051] The second sleeve 42 is closed at one end and has multiple sets of water inlet holes 43. An angle α is formed between the water inlet holes 43 and the shaft diameter of the second sleeve 42; angle α is between 10° and 30°. The closed end, combined with the water inlet holes 43, ensures that water can only enter the inlet pipe through the water inlet holes 43. The angle formed between the water inlet holes 43 and the shaft diameter guides the water flow into the inlet pipe at a suitable angle, preventing direct impact on the interior of the floatation box 16, reducing disturbance to the device, and also filtering out larger floating objects to a certain extent, ensuring the relative cleanliness of the water entering the floatation box 16.

[0052] like Figure 2 , Figure 3 , Figure 6 , Figure 7 As shown, a winch 31 is installed at the top of the inlet / outlet pipe 13, and a rope is installed on the winch 31, one end of which is connected to one of the monitoring components. A partition 32 is installed inside the inlet / outlet pipe 13, dividing it into a lifting area and a component area. Multiple monitoring components are located in the lifting area, while the winch 31 is located in the component area. The rope passes between the component area and the lifting area. Two sets of connecting frames 33 are installed at the bottom of the partition 32, and brushes 34 are installed on the connecting frames 33. The rope passes between the two sets of brushes 34 and contacts the brushes 34. The winch 31 is installed at the top for easy rope winding and unwinding, driving the monitoring components to rise and fall. The partition 32 divides the inlet / outlet pipe 13 into sections, ensuring that the winch 31 and other components do not interfere with each other, guaranteeing their normal operation. The connecting frames 33 and brushes 34 clean the surface of the rope during its up-and-down movement, removing impurities adhering to the rope and preventing impurities from entering the component area and affecting the operation of the winch 31 and other components. They also reduce rope wear and extend the rope's service life.

[0053] The monitoring device includes a first housing 51 and a second housing 52, which are connected to form a spherical mounting portion. The mounting portion contains a detection area and a mounting area. Multiple through-slots are formed on both the first and second housings, allowing the detection area to communicate with the outside environment. A water quality sensor 53 and a processing module 54 are located within the mounting area. A probe is mounted on the water quality sensor 53 and extends into the detection area. The processing module 54 is electrically connected to both the water quality sensor 53 and the controller 14. The spherical mounting portion design minimizes water flow resistance, enabling more stable detection. The through-slots ensure full contact between the detection area and the surrounding water, allowing the probe of the water quality sensor 53 to accurately detect various water parameters. The water quality sensor 53 can be a YSI 5739 water quality sensor. The water quality sensor 53 detects water quality parameters. The processing module 54 performs preliminary processing on the data from the sensor and then sends the processed data to the controller 14. The processing module 54 can be an Arduino Nano 33 IoT processing module.

[0054] Multiple monitoring components are arranged in a straight line along the axis and connected by connecting ropes. The topmost monitoring component is connected to the rope, and the bottommost monitoring component is connected to a drop block 55 via a connecting rope. The drop block 55 is conical in shape. A protective cover 56 is installed at the bottom of the inlet / outlet pipe 13. The protective cover 56 is funnel-shaped, with its wide opening facing the lower water area, which can cover a large area of ​​the bottom entrance of the inlet / outlet pipe 13 and guide objects below to approach smoothly. As the drop block 55 rises with the monitoring components, the funnel-shaped inner wall can automatically correct its deviation direction, gradually guiding the drop block 55 to the center position of the inlet / outlet pipe 13 through the inclined curved surface. Even if the position of the falling block 55 is shifted due to water flow, the special shape of the protective cover 56 can use the guiding force generated by the water flow along the wall to make the falling block 55 rise smoothly along the inner wall and eventually enter the inlet / outlet pipe 13. This avoids collision with the pipe wall of the inlet / outlet pipe 13 due to positional deviation, or getting stuck at the pipe opening and unable to enter, ensuring that the monitoring component rises and falls smoothly without obstruction.

[0055] Multiple monitoring elements are arranged axially to ensure orderly detection of different water layers. The conical design of the drop block 55 straightens the connecting rope under gravity, keeping the monitoring elements vertical and ensuring the accuracy of the detection data. At the same time, the conical structure experiences less resistance in the water, reducing the lateral impact of water flow on the monitoring elements. The protective cover 56 prevents large debris from entering the inlet / outlet pipe 13, avoiding debris from entangled in the monitoring elements or affecting the operation of components such as the winch 31, thus ensuring the normal operation of the device.

[0056] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments.
