[0067] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will be described with reference to the accompanying drawings. Figures 1 to 11 The technical solutions of the present invention are clearly and completely described in detail with reference to the accompanying drawings and specific embodiments.

[0068] Example 1:

[0069] The surface water collection device of the embodiment of the present invention includes: a main body 1, a water collection component 2, a drainage component 3, a cleaning component 4, a controller 5, a positioning module 7, a depth sensor 8 and a detection and analysis component 9.

[0070] The main body 1 comprises a cylinder 11, a top cover 12, and a base 13. The cylinder 11 is open at the top and closed at the bottom. A removable top cover 12 is installed on the top, and the bottom is supported by the base 13. The interior of the cylinder 11 forms a chamber. An air outlet pipe 14 extends through the top cover 12. A one-way exhaust valve is installed in the air outlet pipe 14. During water collection, air inside the cylinder 11 is discharged through the air outlet pipe 14.

[0071] The water collection assembly 2 is mounted on the sidewall of the cylinder 11 and is fluidically connected to the interior of the cylinder 11. It is configured to direct surface water into the chamber of the cylinder 11 through the water collection assembly 2. Specifically, the water collection assembly 2 comprises a first pipeline 21 connected to the sidewall of the cylinder 11. The first pipeline 21 is serially connected to a water inlet control valve 22 and a water pump 23 fixed to the sidewall of the base 13. The water inlet end of the water pump 23 is connected to a telescopic tube assembly 25 via a second pipeline 24. The distal end of the telescopic tube assembly 25 is connected to a removable water collection guide 26 via a mounting base 29. One end of the telescopic tube assembly 25 is detachably connected to the other end of the second pipeline 24. The telescopic tube assembly 25 is composed of multiple stages of telescopic tubes that are sequentially slidably connected, with adjacent stages forming an axial sliding pair. The water collection guide 26 is detachably connected to the other end of the telescopic tube assembly 25. The water collection guide 26 is bell-shaped.

[0072] When the surface water collection device is in use, after one end of the telescopic tube assembly 25 is connected to the water collection guide 26, the telescopic tube assembly 25 is extended to a predetermined length. The other end of the telescopic tube assembly 25 is connected to the second pipeline 24. A portion of the telescopic tube assembly 25 and the water collection guide 26 are extended into the water body. The main body 1, the first pipeline 21, the water inlet control valve 22, the water pump 23, the second pipeline 24, and a portion of the telescopic tube assembly 25 are above the water surface. The water pump 23 is running, directing water from the water collection guide 26 through the telescopic tube assembly 25 and into the cylindrical body 11.

[0073] A locking device is installed between adjacent telescopic tubes in the telescopic tube assembly 25 to secure the connection. Specifically, the locking device can employ a spiral locking structure. The outer tube is externally threaded, and the inner tube nests within it. A locking nut fits over the outer tube's end and engages with the outer tube's threads. When the threaded ring is rotated clockwise, the helix angle of the threads converts the rotational motion into axial movement, pushing the locking nut toward the base of the tube. The locking surface (or tapered surface) of the locking nut compresses the friction bushing, which expands inward under radial force, compressing the outer wall of the inner tube. The static friction between the inner and outer tubes increases with increasing pressure, ultimately locking the relative position. Counterclockwise rotation of the threaded ring releases the axial pressure, allowing the friction bushing to elastically recover and the inner tube to resume its sliding state. The locking device can employ an eccentric / cam locking structure. By turning the eccentric lever, the cam compresses the tube wall, achieving locking. The locking device can also adopt a clamping structure, and the inner tube wall is provided with an array of clamping holes spaced apart along the axial direction; the clamping mechanism includes an elastic movable part and a locking clamp, the elastic movable part has a fixed end and a free end, wherein the fixed end is fixed at the proximal end of the base tube, and the free end extends to the outer circumferential surface of the inner tube and is rigidly connected to the locking clamp; the locking clamp is configured to selectively form a positioning match with any clamping hole. When the locking clamp is embedded in the corresponding clamping hole, an axial limit is formed on the outer tube and the inner tube. The locking clamp can be separated from the clamping hole by applying a radial force to deform the elastic movable part.

[0074] The drain assembly 3 is located at the bottom end of the sidewall of the cylinder 11 and is fluidically connected to the interior of the cylinder 11. It is configured to drain surface water from the accommodating chamber of the cylinder 11 through the drain assembly 3. Specifically, the drain assembly 3 includes a drain pipe 31 and a drain control valve 32. The drain pipe 31 is located at the bottom end of the sidewall of the cylinder 11 and is fluidically connected to the interior of the cylinder 11. The drain control valve 32 is located on the drain pipe 31 and is electrically connected to the controller 5.

[0075] The cleaning component 4 passes through the bottom of the cylinder 11 horizontally, and part of the structure extends into the accommodating chamber, and the exposed part is arranged at the bottom edge of the cylinder 11. The cleaning component 4 is configured to perform a cleaning operation on the accommodating chamber of the cylinder 11 through the cleaning component 4. Specifically, the cleaning component 4 includes a drive motor 41, which is installed inside the base 13; a rotating shaft 42, one end of which is transmission-connected to the output end of the drive motor 41; a turbine turntable 43, which is fixedly arranged at the other end of the rotating shaft 42, and the turbine turntable 43 includes a fixed disk 431 and a plurality of curved blades 432 circumferentially arranged on the side of the fixed disk 431, and the rotating shaft 42 is fixedly connected to the center position of the fixed disk 431; a limiting cap 44, which is coaxially sleeved on the end of the rotating shaft 42; and a rotating shaft limiting member 45, whose fixed end is rigidly fixed to the bottom end face of the cylinder 11, and the working end forms a rotational clearance fit with the outer wall of the rotating shaft 42. A limiting cap 44 is located at the end of the shaft 42 away from the drive motor 41. It serves to restrict the turbine disc 43 on the shaft 42, preventing axial displacement of the turbine disc 43. The fixed end of the shaft limiting member 45 is rigidly connected to the bottom end surface of the cylinder 11. A rotational clearance is maintained between the working end of the shaft limiting member 45 and the outer wall of the shaft 42. This radial displacement constraint on the shaft 42 effectively suppresses radial offset of the shaft 42 caused by high-speed rotation of the turbine disc 43, ensuring coaxial transmission accuracy between the drive motor 41 and the driven component.

[0076] The drive motor 41 is a waterproof brushless motor, the stator winding of which is encapsulated with H-class insulation material, and torque is transmitted between the rotor assembly and the rotating shaft 42 via a spline structure.

[0077] In order to seal the rotating shaft 42 and the cylinder 11, a plurality of sealing rings are provided on the outer wall of the rotating shaft 42. The plurality of sealing rings can be arranged at equal intervals. The sealing rings fit tightly with the rotating shaft 42, the rotating shaft limiter 45 and the cylinder 11, respectively, to ensure the sealing of the connection between the rotating shaft 42, the rotating shaft limiter 45 and the cylinder 11.

[0078] The controller 5 is built into the base 13 and electrically connected to the water sampling assembly 2, drainage assembly 3, and cleaning assembly 4. It integrates a wireless communication module to enable remote control from a mobile terminal. Furthermore, the controller 5 also includes a control module, a wireless communication module, and a data storage module. The controller 5 is configured to control the opening and closing of the water sampling assembly 2 to initiate and terminate water sampling operations; the opening and closing of the drainage assembly 3 to initiate and terminate drainage operations; and the opening and closing of the cleaning assembly 4 to initiate and terminate cleaning operations. The control module may include a programmable logic control unit (such as a PLC or CPU), memory, and electronic components connected to the programmable logic control unit, as is well known to those skilled in the art and will not be described in detail here. The wireless communication module is used to remotely transmit sampling data, device status, and other information to a mobile terminal, facilitating real-time monitoring and data analysis. The wireless communication module can also receive remote commands, enabling remote control of the device. The wireless communication module is a Bluetooth or Wi-Fi module. The data storage module stores device operating status and water sampling information and works in conjunction with the wireless communication module to transmit information.

[0079] The controller is equipped with a speed / direction feedback unit that dynamically adjusts the turbine disc speed and direction, enabling adaptive adjustment of cleaning intensity. The unevenly arranged curved blades of the turbine disc, combined with dynamic speed adjustment, create a cleaning flow field with alternating turbulent and laminar flows.

[0080] Curved blades 432 are arranged circumferentially on the fixed disk 431 (specifically, 6 to 30 curved blades are arranged on the fixed disk 431, and the number of curved blades is flexibly selected based on the diameter of the turbine disk 43 and the required operating conditions. The number affects the vortex frequency and fluid coverage density). Curved blades 432 are evenly arranged circumferentially on the fixed disk 431.

[0081] In addition, the curved blades 432 are unevenly distributed circumferentially around the fixed disk 431, i.e., the curved blades 432 are distributed in a "sparse-dense-sparse-dense" pattern around the circumference of the fixed disk 431. When the turbine disk 43 rotates, the difference in pitch between the curved blades 432 and the rotation of the turbine disk 433 cause two key effects on the fluid:

[0082] When turbine disk 43 rotates forward, the water in the wide-spaced area of ​​the curved blades 432 fully diffuses, forming a wide laminar flow zone. The water in the narrow-spaced area of ​​the curved blades 432 is compressed and accelerated, thereby enhancing the wall-adhering effect (high-speed water flows closely against the working surfaces of the curved blades 432, reducing the boundary layer thickness by 40% and increasing the shear force on the cylinder wall). This achieves extensive laminar flow coverage throughout the entire housing cavity of cylinder 11.

[0083] When the turbine disk 43 rotates in the reverse direction, the fluid in the small-pitch area of ​​the curved blades 432 is strongly sheared, generating high-frequency vortices. The vortices in the large-pitch area of ​​the curved blades 432 extend downstream, expanding the turbulent impact range. A full-area turbulent impact network is formed in the accommodating cavity of the cylinder 11.

[0084] The turbine turntable with non-uniformly distributed curved blades rotates to form forward laminar coverage and reverse turbulent impact, and the dirt removal rate is increased by 30% to 50% compared with traditional uniformly distributed blades.

[0085] A driving motor is provided in the surface water collection device, and a turbine turntable is provided in the cylinder. The driving motor drives the turbine turntable to rotate at high speed, realizing a rinsing function. Before sampling, the device automatically extracts a small amount of water sample to be tested, and the cleaning component operates to rinse the inside of the cylinder to ensure the purity and accuracy of the sampling. Before sampling, the surface water collection device extracts a small amount of water sample to be tested through the water sampling component 2 to rinse the inside of the cylinder 11 to ensure the purity and accuracy of the sampling. When the water sampling guide 26 reaches the required water sampling position, the water inlet control valve 22 and the water pump 23 are started to supply water to the inside of the cylinder 11, and the cleaning component 4 cleans the inside of the cylinder 11. After the cleaning reaches the preset time, the water inside the cylinder 11 is discharged through the drainage component 3, and the water sampling component 2 is started again to collect water. When the water volume inside the cylinder 11 reaches the water collection volume requirement, water intake is stopped.

[0086] The positioning module 7 and depth sensor 8 are fixed to the mounting base 29 and electrically connected to the controller 5. The detection and analysis component 9 includes a water quality parameter sensing unit and a signal processing unit. The water quality parameter sensing unit integrates a pH sensor, a water temperature sensor, a dissolved oxygen sensor, a conductivity sensor, and a turbidity sensor. The detection and analysis component 9 analyzes the pH, dissolved oxygen, water temperature, conductivity, and turbidity of the water sample. The detection end of the water quality parameter sensing unit is housed in the housing 11. The signal processing unit establishes a communication connection with the control module of the controller 5 via a data cable, converting the analog signals collected by each sensor into digital signals and transmitting them to the control module for water quality parameter analysis. The positioning module 7 is specifically a Beidou GPS-ATGM332D module, which accurately determines the geographic location of the water intake. The depth sensor 8 receives control commands from the control module, monitors the water depth at the water intake location, and transmits the measured water depth value to the control module. The depth sensor 8 can be a pressure sensor, ultrasonic sensor, laser sensor, radar sensor, or other sensor.

[0087] The connection between the positioning module 7 and the depth sensor 8 and the control module of the controller 5 enables automated control of the device. Specifically, when the water sampling guide 26 is at the desired water sampling position, the water inlet control valve 22 and water pump 23 automatically activate to supply water to the interior of the cylinder 11. The cleaning component 4 automatically cleans the interior of the cylinder 11. After the cleaning period has been set, the water inside the cylinder 11 is automatically drained through the drainage component 3. The water inlet control valve 22 and water pump 23 are then activated to collect water. When the water volume inside the cylinder 11 reaches the required water collection volume, water inlet is stopped. Once the water inside the cylinder 11 is stable, the water quality parameter sensing units of the detection and analysis component 9 detect the water quality. The analog signals collected by each sensor are converted into digital signals by the signal processing unit and transmitted to the control module. This information is then transmitted to the mobile terminal via the wireless communication module for water quality parameter analysis. After the detection and analysis component 9 completes its monitoring, the drainage component 3 drains the water inside the cylinder 11. The drainage component 3 can also be connected to a sampling bottle, which stores the sampled water for subsequent testing and analysis. The automated operation of the surface water collection device reduces human factors and improves the data accuracy of water collection analysis.

[0088] The surface water collection device also includes a power supply assembly 6, built into the base 13 and electrically connected to the water collection assembly 2, drainage assembly 3, cleaning assembly 4, and controller 5. This assembly provides power for the entire device. The power supply assembly 6 is electrically connected to the water pump 23 of the water collection assembly 2, the drive motor 41 of the cleaning assembly 4, and the controller 5. The power supply assembly 6 includes a battery pack and a charge-discharge management module. This module dynamically controls the charge and discharge process by real-time monitoring of battery voltage and current parameters, ensuring energy supply stability and battery life.

[0089] In some embodiments, the water sampling assembly 2 further includes a liquid level sensor 28 disposed on the barrel 11. The sensing portion of the liquid level sensor 28 is located within the receiving chamber of the barrel 11 and is electrically connected to the controller 5. When the water within the barrel 11 reaches the height of the liquid level sensor 28, the liquid level sensor 28 transmits the monitored liquid level information within the barrel 11 to the control module, which then controls the water pump 23 to stop supplying water and close the water inlet control valve 22. The liquid level sensor 28 may include a float level sensor, a capacitive level sensor, or a magnetostrictive level sensor.

[0090] In some embodiments, the top cover 12 is a shell structure, such as Figure 7 and Figure 8As shown, the top cover 12 includes a blocking portion 121 and an inserting portion 122; an elastic sealing ring 123 is provided on the outer wall of the inserting portion 122; when the top cover 12 is installed on the cylinder 11, the blocking portion 121 contacts the upper end surface of the cylinder 11 to form an axial limit fit, the inserting portion 122 extends into the accommodating chamber to a predetermined insertion depth, and the elastic sealing ring 123 contacts the inner wall of the cylinder 11.

[0091] Furthermore, in order to facilitate manual removal of the top cover 12 from the cylinder 11 , the circumferential outer wall of the blocking portion 121 is provided with a plurality of grooves 124 spaced apart along its circumferential direction. The plurality of grooves 124 are distributed in a circular array with the axis of the blocking portion 121 as the center.

[0092] In order to prevent impurities in the surface water from being collected into the cylinder 11 during the collection process, a filter 27 is provided on the outside of the water guide 26. Figure 10 shown.

[0093] The surface water collection device emits a beep or vibrates when it reaches the preset sampling point, ensuring the accuracy of the sampling point. This improves the positioning accuracy of the sampling point, ensures the representativeness and reliability of the sampled data, and reduces duplicate or missed sampling due to inaccurate positioning.

[0094] The surface water collection device has a modular design, and each functional component can be disassembled and cleaned independently, which improves the reliability and maintainability of the equipment.

[0095] The surface water collection device replaces the existing manual cleaning method of the surface water collection device by setting up a cleaning component, thereby improving the use efficiency, reducing the problem of uneven cleaning existing in manual cleaning, and reducing human errors; at the same time, the surface water collection device is equipped with a controller, a positioning module, a depth sensor and a detection and analysis component, which realizes the intelligence of the device, facilitates the collection of surface water and improves the accuracy of the collected data.

[0096] Example 2:

[0097] The embodiment of the present invention provides a method for using the surface water collection device of embodiment 1, comprising the following steps:

[0098] S1. Move the main body 1 above the surface water to be measured;

[0099] S2. After connecting one end of the telescopic tube assembly 25 to the water collection and flow guide 26, extend the telescopic tube assembly 25 to a predetermined length and connect the other end of the telescopic tube assembly 25 to the second pipeline 24.
