Description

Technical Field

[0001] This invention belongs to the technical field of water source detection and sampling equipment, specifically relating to a wide-area deep water source detection and sampling device. Background Technology

[0002] With the escalating global water pollution problem and the increasing demand for deep water research, the need for such research is becoming increasingly urgent. Marine resource development and research require a precise understanding of the impact of ocean currents at different depths on sediment distribution, while freshwater monitoring and remediation necessitate a clear understanding of the pollution characteristics of water layers at different depths. Therefore, aquatic environmental exploration, monitoring, and sampling, as a prerequisite for resource development, aims to construct a multi-dimensional water environment database to provide a scientific basis for subsequent development. Currently, most mainstream water quality monitoring and sampling devices rely on fixed-point buoys or manual diving sampling, and existing water quality monitoring technologies are insufficient to meet the demands for wide-area, deep, and efficient water source monitoring.

[0003] Patent publication number CN119223675B discloses a hydrogeological exploration water source sampling and testing device, including a sampling shell. Both sides of the sampling shell are provided with reaction shells, and the bottom of the two reaction shells are provided with the same counterweight. The interior of the reaction shells is filled with reactants. The interior of the sampling shell is provided with several partition plates, which divide the interior of the sampling shell into a transition cavity and several sampling chambers. The transition cavity is located at the top inside the sampling shell. This invention ensures that the sampling shell can quickly and vertically descend, avoiding significant displacement caused by lateral water flow impact during descent, thus preventing sampling of the target water area. It further reduces the resistance when lifting the sampling shell after sampling, facilitating rapid and effortless lifting to the water surface after sampling. It is convenient to use and has a compact structure.

[0004] While the above-mentioned technical solutions have solved the technical problems of underwater water source detection and collection, the following issues still exist: they can only achieve local water area collection and monitoring, making it difficult to cover the dynamic changes of large water areas (such as lakes, nearshore areas, and reservoirs); and they rely on manual or periodic sampling, making it impossible to achieve continuous collection and monitoring over long periods of time. Summary of the Invention

[0005] This invention provides a wide-area deep water source detection and sampling device. By combining a mobile platform with a floating structure, it can be operated both on land and on the water. With the help of a small crane's electromagnet adsorption and deployment system, it can achieve seamless operation between the water area and the shore, breaking through the limitations of traditional sampling equipment on the working environment and significantly improving the accessibility of complex water areas. The device adopts a winch, multiple piston rods and multiple sampling cups. By vertically lowering the sampler and using an ultrasonic depth sounder for real-time monitoring, it can achieve precise positioning and sampling of deep water bodies from 0 to 50 meters. It solves the technical problems of existing water quality detection and sampling devices that can only achieve local water area sampling and monitoring, making it difficult to cover the dynamic changes of large water areas (such as lakes, nearshore areas and reservoirs); and that rely on manual or periodic sampling, making it impossible to achieve long-term continuous sampling and monitoring.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: A wide-area deep water source detection and sampling device includes a mobile platform with a fixed compartment and a small crane. The water source detection and sampling device is placed in the fixed compartment. The device includes two floats, a mounting plate, and a power box. The mounting plate is mounted on the two floats, and a fixed plate is located on the upper side of the mounting plate. A sampling hole is opened on the mounting plate. A sampling mechanism and a driving mechanism are provided on the mounting plate. The sampling mechanism includes a winch, a collector, and a collection cup. The collector has a hanging ring, and the pull rope of the winch is connected to the hanging ring. The collector has a cylindrical structure. A power box and a control box are located on the top of the collector, and the bottom of the collector has a pointed bottom. A ring of mounting holes is provided on the top side edge of the collector. A piston rod is correspondingly set above each mounting hole, and a fastening screw is provided on the rear side of each piston rod. The collection cup is fixed in the mounting hole by the fastening screw. The top of the collection cup has a hinged cover with a corresponding first push plate and a second push plate. A mounting block is provided on the side of the collection cup, and a compression spring is provided between the mounting block and the second push plate.

[0007] The driving mechanism includes a driving rod, a water pump, an inlet pipe, and a spray pipe. The water pump is fixed on the mounting plate, and the inlet pipe passes vertically through the mounting plate. The top of the inlet pipe is connected to the water pump inlet via a flexible hose. The spray pipe is located behind the inlet pipe, and the top of the spray pipe is connected to the water pump outlet via a flexible hose. The bottom of the spray pipe has a rearward-facing propulsion nozzle. The spray pipe is equipped with a limiting plate and an operating plate. The limiting plate is located above the mounting plate, and the operating plate is located above the limiting plate. One end of the driving rod is hinged to the mounting plate, and the other end of the driving rod is hinged to the operating plate.

[0008] The bottom of the collection cup is equipped with a vacuum suction port, which has a one-way valve. The inner side of the lid of the collection cup is equipped with a rubber sealing layer.

[0009] The bottom of the fixed plate is equipped with guide wheels, and the winch's pull rope is connected to the collector through the guide wheels.

[0010] The control box on top of the data collector contains a controller, an ultrasonic depth detector, and a Beidou positioning device.

[0011] The power box on the mounting plate contains a power source and a controller, the power source being an internal combustion generator or a battery.

[0012] A monitoring camera is installed at the bottom of the fixing plate.

[0013] The bottom of the water inlet pipe of the drive mechanism is equipped with an impurity filter.

[0014] The small crane is equipped with an electromagnet on its lifting head. The small crane uses the electromagnet to attract and fix the plate to realize the raising and lowering of the water source detection and sampling device.

[0015] The controller inside the power box is either a wireless controller or a wired controller.

[0016] Beneficial effects By adopting the above technical solution, the beneficial effects of the present invention are: The present invention provides a wide-area deep water source detection and sampling device. By combining a mobile platform with a floating structure, it can be both mobile on land and floating on the water. With the help of the electromagnet adsorption and retrieval system of a small crane, it can achieve seamless connection between water area and shore base, break through the limitations of traditional sampling equipment on the working environment, and significantly improve the accessibility of complex water areas. Employing a winch, multiple piston rods, and multiple sampling cups, the system vertically lowers the sampler and uses an ultrasonic depth sounder for real-time monitoring, enabling precise positioning and sampling of deep water bodies ranging from 0 to 50 meters. The collection cup features an empty suction port and a one-way valve design, with a rubber sealing layer and vacuum suction providing dual protection. The spring cover structure enables automatic opening and closing, effectively preventing contamination from water layers at different depths and ensuring sample purity. Integrating Beidou positioning, wireless controller and monitoring camera, it realizes remote control operation and real-time image transmission. Operators can complete the entire process of positioning, lowering, data collection and retrieval in a safe area on the shore, which greatly reduces the risk of water operations. The power box integrates an internal combustion generator or battery pack to provide a stable power supply for electrical equipment such as winches, water pump drives, and cameras. The float, power box, and data acquisition mechanism all adopt standardized interface design, allowing for quick replacement of different specifications of data acquisition devices, data acquisition cups, and sensor modules according to testing needs.

After collection is completed, the lid 18 automatically closes under the action of the compression spring 22.

[0034] After the data collection is completed, the winch 9 is activated to retrieve the collector 10 back to the water surface. Once the operator confirms the collector 10 is functioning correctly via a monitoring camera, a small crane 3 is used to hoist the device back into the fixed chamber 2. The collected water sample is then sent to the laboratory for further analysis.

[0035] This invention enables precise location sampling of deep water sources over a wide area, significantly improving accessibility and sampling efficiency in complex waters. Simultaneously, it integrates advanced technologies such as BeiDou positioning, wireless controllers, and monitoring cameras, achieving remote control operation and real-time image transmission, greatly reducing the risks of waterborne operations.
