Description

Technical Field

[0001] This utility model relates to the field of surface water monitoring technology, and in particular to an automatic surface water sampling device. Background Technology

[0002] In the field of surface water pollution monitoring, timely and flexible collection of water samples from different water areas and locations is crucial for pollution source tracing and early warning prediction. However, existing water sampling devices generally suffer from insufficient flexibility in sampling areas and limited sampling points, making it difficult to meet the diverse monitoring needs in complex aquatic environments.

[0003] For example, in patent "CN105651552B, A Floating Surface Water Sampling Device", the device includes a float, a lifting frame, and a water collection bucket. The float floats in a fixed water area to collect samples. Although it can automatically collect surface water, the float adopts a fixed-point floating method, which can only collect water in a fixed area and cannot be flexibly moved to different water areas according to monitoring needs. At the same time, the number of water collection buckets is fixed and corresponds to a single water collection point, making it difficult to simultaneously sample and compare different points in the same water area or different water areas. As a result, in scenarios such as tributary confluence and complex distribution of sewage outlets, it is impossible to obtain comprehensive water quality data, which limits the accuracy and timeliness of pollution source tracing.

[0004] Therefore, how to design a water sampling device that can flexibly adjust the water sampling area and enrich the water intake points to adapt to complex aquatic environments has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0029] Example 1

[0030] Please see Figure 1 This utility model provides an automatic surface water sampling device. Currently, the monitoring of surface water pollution mainly relies on cross-sectional water quality monitoring stations, which typically collect water samples hourly for analysis, resulting in significant timeliness issues. Furthermore, the limited density of water quality monitoring stations makes it difficult to achieve rapid monitoring and accurate source tracing in the event of an environmental pollution incident, hindering effective early warning and prediction.

[0031] Existing technologies have shortcomings in terms of real-time performance, power supply convenience, water sampling area flexibility, water sampling point diversity, and the adjustability of the number of water sampling buckets, making it difficult to achieve timely and accurate early warning and prediction and precise source tracing when facing complex and ever-changing pollution situations.

[0032] Please see Figure 1 and Figure 2 In this embodiment, the provided automatic sampling device includes a water surface mover 100 and a water sampling mechanism 200; the water surface mover 100 includes a support part 110 that can float on the water surface and a drive part 120 for driving the support part 110 to move on the water surface, the drive part 120 being disposed at the tail of the support part 110; the water sampling mechanism 200 includes a lifting frame 210 and a water sampling bucket 300 disposed on the lifting frame 210 and capable of entering the water based on the lifting frame 210 to perform water sampling operations; the support part 110 is also provided with a mounting plate 1 12. The mounting plate 112 is mounted on the bearing part 110 by a plurality of support columns 113; the bearing part 110 is also provided with a plurality of water intake holes 111, through which the water collection bucket 300 can enter the water to collect water; each of the water intake holes 111 is provided with a water collection mechanism 200 on the mounting plate 112; it also includes a main control module mounted on the mounting plate 112, used to control the running speed and direction of the drive unit 120, thereby precisely adjusting the position of the water surface mover 100 on the water surface to meet the needs of different water collection areas.

[0033] The main control module is also connected to the water collection mechanism 200, which can control the lifting height of the lifting frame 210 according to preset instructions, thereby enabling the water collection bucket 300 to carry out water collection operations in waters of different depths, greatly improving the diversity of water collection points.

[0034] Meanwhile, the main control module has intelligent adjustment capabilities, which can flexibly adjust the number of water sampling tanks 300 deployed according to the actual pollution monitoring needs. When facing areas with high pollution levels and large areas, the main control module can control more water sampling units 200 to lower water sampling tanks 300, ensuring that enough samples are collected for accurate analysis.

[0035] In use, the main control module and the driver first drive the carrier 110 to move to the target water area. The carrier 110 of the water surface mover 100 can float on the water surface, and the drive unit 120 at its tail can drive the carrier 110 to move on the water surface, thereby moving the device to the target water area where water needs to be collected.

[0036] Please see Figure 2 The supporting part 110 is provided with a plurality of water intake holes 111, and each water intake hole 111 is provided with a water collection mechanism 200 on the mounting plate 112 corresponding to the mounting plate 112. The water collection bucket 300 in the water collection mechanism 200 can enter the water through the water intake holes 111 based on the lifting frame 210 to carry out water collection. That is, by the movement of the lifting frame 210, the water collection bucket 300 is driven down into the water to complete the water collection, and then the water collection bucket 300 is lifted to the surface of the supporting part 110 to complete the water collection operation, and then returns via the drive part 120.

[0037] Typically, using the crucial facility of cross-sectional water quality monitoring stations, once abnormal or exceeding data points are detected, this vital information is rapidly transmitted to the main control center. At the main control center, the joint dispatch center combines the received data with numerous relevant factors such as upstream rainfall and cross-sectional flow, and then uses advanced AI calculation models for comprehensive and integrated analysis. In this way, source tracing work is initiated for upstream tributaries suspected of having abnormal conditions, as well as areas or sewage outlets requiring close monitoring.

[0038] During this process, the system can automatically collect water samples and properly store them. Furthermore, the system has an automatic task dispatch function, capable of issuing commands to unmanned surface vessels (USVs) to navigate to designated water surface locations and automatically collect water samples. After collection, the system matches the corresponding detection and analysis results with pollutant sequence maps. This method effectively ensures the consistency of upstream and downstream water quality data while guaranteeing the timeliness of water sample collection, thus providing strong support for accurate source tracing of pollution and facilitating better water quality protection and pollution control efforts.

[0039] Further, please see Figure 2 and Figure 3The drive unit 120 includes a first drive unit 122 and a second drive unit 130, which are hinged to each other via a connecting rod 121 and symmetrically arranged at both ends of the connecting rod 121. The first drive unit 122 includes a first guide rod 123 and a first blade assembly 124 that can rotate based on the first guide rod 123. The first drive unit 122 also includes a drive motor for driving the first blade assembly 124. The output shaft of the drive motor is connected to the first blade assembly 124 through the interior of the first guide rod 123. The second drive unit 130 has the same structure as the first drive unit 122.

[0040] Furthermore, the first drive unit 122 also includes a first base rod 126 connected to the first guide rod 123 via a first connector 125, and the first base rod 126 is fixedly connected to one end of the bearing part 110; the bottom of the first guide rod 123 is also provided with a first guide vane 127; the first connector 125 is configured as a corrugated pipe type expansion joint.

[0041] Furthermore, a first steering cylinder 128 is also hinged to the inner side of the first guide rod 123. The piston rod of the first steering cylinder 128 is hinged to the first guide rod 123, and the other end of the first steering cylinder 128 is fixedly connected to the bearing part 110.

[0042] Furthermore, the second drive unit 130 includes a second guide rod 131 and a second blade assembly 132 that can rotate based on the second guide rod 131. The second drive unit 130 also includes a drive motor for driving the second blade assembly 132. The output shaft of the drive motor is connected to the second blade assembly 132 through the interior of the second guide rod 131.

[0043] The second drive unit 130 also includes a second base rod 134 connected to the second guide rod 131 via a second connector 133, and the second base rod 134 is fixedly connected to one end of the bearing part 110; the bottom of the second guide rod 131 is also provided with a second guide vane 135; the second connector 133 is configured as a corrugated tube type expansion joint.

[0044] Furthermore, a second steering cylinder 136 is also hinged to the inner side of the second guide rod 131. The piston rod of the second steering cylinder 136 is hinged to the second guide rod 131, and the other end of the second steering cylinder 136 is fixedly connected to the bearing part 110.

[0045] When steering, the piston rod of the first steering cylinder 128 or the second steering cylinder 136 extends to drive the first guide rod 123 or the second guide rod 131. Since the first guide rod 123 and the second guide rod 131 are connected by the connecting rod 121, the first guide rod 123 or the second guide rod 131 rotates synchronously based on the first joint 125 and the second joint 133, so that the first guide vane 127 and the second guide vane 135 provided on the first guide rod 123 or the second guide rod 131 offset synchronously to achieve the adjustment of the preset angle and realize the reversing movement.

[0046] Specifically, the first drive unit 122 and the second drive unit 130 are each equipped with an independent steering actuator; the first steering cylinder 128 corresponds to the first guide rod 123 and the second steering cylinder 136 corresponds to the second guide rod 131.

[0047] When steering is required, the main control module controls the piston rod of the first steering cylinder 128 or the second steering cylinder 136 to extend or retract, and the piston rod pushes or pulls the corresponding first guide rod 123 or second guide rod 131 through the hinge point.

[0048] The first guide rod 123 and the second guide rod 131 are hinged together by the connecting rod 121 to form a rigid linkage structure; at the same time, the two are respectively connected to the first base rod 126 and the second base rod 134 fixed on the bearing part 110 through the corrugated pipe type expansion joint (first joint 125, second joint 133).

[0049] When a single guide rod (first guide rod 123 or second guide rod 131) is pushed by the corresponding steering cylinder, the other guide rod (second guide rod 131 or first guide rod 123) will rotate synchronously with it due to the constraint of the connecting rod 121; the bellows-type joint can adapt to the angle change and small displacement when the guide rod rotates, ensuring smooth rotation without jamming.

[0050] The bottom of both the first guide rod 123 and the second guide rod 131 is provided with guide vanes (first guide vane 127 and second guide vane 135), the angle of which shifts synchronously with the rotation of the guide rod. The change in the angle of the guide vane changes the direction of the reaction force of the water flow on the vane, thereby pushing the bearing part 110 to turn in the target direction; for example, when the vane shifts to the left, the reaction force of the water flow drives the device to turn to the left, realizing the precise adjustment of the preset angle.

[0051] Specifically, this steering structure offers high steering flexibility and can adapt to various water areas. Through the symmetrical design of the dual drive units and independent steering cylinder control, the steering structure can achieve small-angle fine adjustments (such as avoiding obstacles) and large-angle steering (such as changing the direction of navigation), meeting the path adjustment needs of complex water areas such as tributaries and sewage outlets.

[0052] The connecting rod 121 ensures that the guide rods on both sides rotate synchronously, avoiding device shaking caused by unilateral offset; the bellows-type joint reduces rotational resistance and coordinates with the angle change of the guide vanes to make the turning process smooth and without jamming, thus improving positioning accuracy.

[0053] The hinged structure between the steering cylinder and the guide rod can withstand the torque caused by water flow impact; the bellows-type joint has both extensibility and sealing properties, preventing water from entering the guide rod and affecting the operation of the drive motor, thus extending the service life of the device.

[0054] The steering structure, in conjunction with the driving functions of the first blade assembly 124 and the second blade assembly 132, can achieve integrated control of "driving + steering", enabling flexible movement without additional complex mechanisms, thus reducing the overall weight and energy consumption of the device.

[0055] Specifically, the steering structure, through the combination of mechanical linkage and pneumatic control, significantly improves the device's steering flexibility and movement efficiency in complex waters while ensuring stability and reliability, providing key support for achieving "multi-area, multi-point" water sample collection.

[0056] Further, please see Figure 4 and Figure 5 The lifting frame 210 includes a mounting frame 220 disposed on a mounting plate 112 at a corresponding position on the top of the water intake hole 111. The mounting frame 220 has a first guide rail 221 and a second guide rail 222 on both sides. The water collection bucket 300 is connected to the first guide rail 221 and the second guide rail 222 via a slider disposed on a connecting frame 230. The top of the mounting frame 220 is provided with a lifting cylinder 240. The piston rod of the lifting cylinder 240 is fixedly connected to the connecting frame 230 to drive the connecting frame 230 to move up and down on the first guide rail 221 and the second guide rail 222.

[0057] Furthermore, the connecting frame 230 is provided with a first mounting arm 231 and a second mounting arm 232 on both sides; the first mounting arm 231 and the second mounting arm 232 are respectively provided with a first rotating seat 233 and a second rotating seat 234; the water collection bucket 300 is mounted on the connecting frame 230 through the first rotating seat 233 and the second rotating seat 234; the first rotating seat 233 and the second rotating seat 234 are respectively provided with a stop 235, and the stop 235 is detachably inserted into the first rotating seat 233 and the second rotating seat 234 to realize the rotation or fixation of the water collection bucket 300.

[0058] Specifically, the stop 235 is made of ferromagnetic material (such as a steel pin), and a waterproof electromagnet is embedded in the rotating base. When not energized, the stop is inserted into the positioning hole under the action of the spring; when energized, the electromagnet generates magnetic force to attract the stop, compressing the spring to make the pin exit the positioning hole; the electromagnet must be IP68 waterproof to avoid water ingress and short circuit, making it suitable for underwater operation.

[0059] Furthermore, the mounting bracket 220 is also provided with a tilting cylinder 250 near the top. The piston rod end of the tilting cylinder 250 is provided with a snap-in part 252 that engages with the snap-in part 251 provided on the water collection bucket 300. When the snap-in part 252 and the snap-in part 251 are connected, the tilting cylinder 250 can drive the water collection bucket 300 to rotate based on the first rotating seat 233 and the second rotating seat 234.

[0060] In use, initially, the water collection bucket 300 is located on top of the mounting frame 220, above the water surface. When water needs to be collected, the lifting cylinder 240 on top of the mounting frame 220 is activated, and its piston rod extends downward. Since the piston rod is fixedly connected to the connecting frame 230, it will drive the connecting frame 230 to move downward synchronously.

[0061] The two sides of the connecting frame 230 are connected to the first guide rail 221 and the second guide rail 222 of the mounting frame 220 through sliders. The sliders slide along the guide rails to provide guidance and support for the lifting and lowering of the connecting frame 230, ensuring that the connecting frame 230 and the water collection bucket 300 installed on it can descend vertically stably.

[0062] The water collection bucket 300 enters the water through the water intake hole 111 on the bearing part 110 along with the connecting frame 230. After the water collection bucket 300 reaches the preset water collection depth and completes water collection, the piston rod of the lifting cylinder 240 retracts, driving the connecting frame 230 and the water collection bucket 300 to rise along the guide rail and return to the initial position, completing one lifting and water collection operation.

[0063] During the water-pouring operation, the water collection bucket 300 is mounted on the first mounting arm 231 and the second mounting arm 232 of the connecting frame 230 via the first rotating base 233 and the second rotating base 234. The rotating bases provide a pivot point for the water collection bucket 300 to rotate. In the initial state, the stop members 235 on the first rotating base 233 and the second rotating base 234 are in the plugged-in state, restricting the rotation of the water collection bucket 300 and keeping it in a stable water-collecting posture.

[0064] When water needs to be poured, the electromagnet is powered on to generate a magnetic force that attracts the stop, and the compressed spring causes the pin to exit the positioning hole, thus releasing the restriction on the rotation of the water collection bucket 300. Subsequently, the tilting cylinder 250 near the top of the mounting bracket 220 is activated, and the locking part 252 at the end of its piston rod mates with and connects to the locking part 251 on the water collection bucket 300.

[0065] The piston rod of the tilting cylinder 250 retracts (or extends, depending on the installation direction), and through the force of the locking part 252 and the locking part 251, it drives the water collection bucket 300 to rotate around the first rotating seat 233 and the second rotating seat 234 as the axis. When the water collection bucket 300 rotates to the preset pouring angle, the water in the bucket is poured into the designated container. After the pouring is completed, the tilting cylinder 250 reverses its action, driving the water collection bucket 300 back to the initial position. Then, by cutting off the power, the stop part 235 is inserted into the positioning hole under the action of the spring, waiting for the next operation.

[0066] Furthermore, it also includes an energy storage unit for powering the water surface mover 100, and a solar panel 114 for powering the energy storage unit, the solar panel 114 being electrically connected to the energy storage unit via wires.

[0067] Furthermore, the solar panel 114 is disposed on the top of the mounting plate 112 by a plurality of the support columns 113 and is spaced apart from the mounting plate 112.

[0068] The energy storage unit and the solar panel 114 form an independent power supply system. The solar panel 114 absorbs light energy, converts it into electrical energy, and stores it in the energy storage unit, providing power to the drive unit 120 (such as a drive motor and steering cylinder) of the water surface mover 100 and the lifting frame 210 (such as a lifting cylinder 240 and a tilting cylinder 250) of the water sampling mechanism 200. This design does not rely on an external power source and is particularly suitable for scenarios lacking power grid coverage, such as remote water areas and field monitoring points. It breaks through the dependence of traditional water sampling devices on fixed power supply facilities and greatly expands the application range of the device.

[0069] Solar energy is a renewable and clean energy source. By generating electricity independently through solar panels 114, the need for battery replacement or fuel-fired power generation can be reduced, lowering energy costs and maintenance frequency during long-term operation. At the same time, the energy storage unit can store excess electrical energy, ensuring that the device can still maintain normal operation for a certain period of time under conditions of insufficient sunlight, such as cloudy days or nights, thus guaranteeing the continuity of water extraction tasks.

[0070] The solar panels 114 are mounted on top of the mounting plate 112 and spaced apart by support columns 113. This arrangement utilizes the unused space above the mounting plate 112 to install the solar panels 114, without occupying the water surface space of the supporting unit 110, thus avoiding interference with the operation of the water intake mechanism 200 or the drive unit 120. Furthermore, the spaced arrangement reduces shading of the solar panels 114 by the mounting plate 112, ensuring that the solar panels 114 can receive maximum sunlight and improve power generation efficiency. In addition, the fixing method of the support columns 113 enhances the stability of the solar panels 114, adapting to the swaying environment during water surface operations.

[0071] The self-powered system eliminates the need for the device to be connected to the shore via cables, reducing the limitations imposed on the device's movement by external factors (such as water flow and terrain). The water surface mover 100 can move more flexibly on the water surface to select sampling points, further enhancing the autonomy and flexibility of water sampling operations.

[0072] Furthermore, the side of the support portion 110 is provided with a plurality of handles 115 at intervals, the handles 115 being used to drag or fix the support portion 110.

[0073] The handles 115 spaced apart on the side of the bearing part 110 are mainly used in two scenarios:

[0074] Firstly, it can be moved by dragging. When it is necessary to move the carrier 110 from its storage location to the water surface (such as the shore or dock) or to drag it from the water surface to land, the operator can apply pulling force by holding the handle 115 and use the force-bearing structure of the handle 115 to move the carrier 110 conveniently.

[0075] Secondly, it can be fixed in place.
