DETAILED DESCRIPTION

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0019] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0020] Example 1 Please refer to Figures 1-8 An embodiment of the present invention provides a sampling device serving an underwater robot, which includes: a working basket 1 and a first support column, a first support plate 2, a second support column 3, a second support plate 4, a drive motor 5, and a working baffle 6 connected in sequence from bottom to top inside the working basket 1. The first support plate 2 is provided with a placement groove 7, and an electric push rod 8 is connected to the bottom of the working basket 1. A working hole 9 is provided in the center of the placement groove 7, and the electric push rod 8 slides through the working hole 9. A transition hole 10 for the bottle body to pass through is provided on the second support plate 4, a water leakage hole is provided at the bottom of the working basket 1, and a guide sleeve 12 is movably connected to the placement groove 7. One end of the working baffle 6 is connected to the output end of the drive motor 5, and the other end is slidably connected to the working basket 1.

[0021] It should be noted that the existing underwater sampling equipment still has shortcomings in actual use: due to the lack of special underwater vehicles, the sampling device cannot move flexibly and freely underwater. At the same time, traditional monitoring methods have also caused serious waste of manpower and material resources. Due to the limitations of terrain and monitoring distance, the real-time monitoring of the environment is limited, making it difficult to achieve relatively ideal results.

[0022] It is worth noting that the sampling device provided in the embodiment of the present invention is designed to work in conjunction with the technology disclosed by the inventor with publication number CN117191474A, and includes a working basket 1. The working basket 1 is cylindrical and has a drainage hole at its bottom. The drainage hole is used to discharge excess water when the sampling device is recovered to reduce the weight of the device; an annular groove is provided on the top of the working basket 1, and one end of the working baffle 6 can be slidably connected in the annular groove, thereby assisting in realizing the rotation function of the working baffle 6; a number of reflective strips 16 are fixedly connected to the outer wall of the working basket 1, and the reflective strips 16 can improve the visibility of the device underwater, making it convenient for the operator to monitor in real time through underwater camera equipment. The inside of the working basket 1 is connected in sequence from bottom to top with the first support column, the first support plate 2, the second support column 3, the second support plate 4, the drive motor 5 and the working baffle 6. The first support column and the second support column 3 are fixedly connected to the inner wall of the working basket 1 to support and stabilize the internal components. The first support column and the drive motor 5 are installed at the bottom of the working basket 1, and the first support plate 2 is installed above the second support column 3. The first support plate 2 is connected to the second support plate 4 through the second support column 3.

[0023] Furthermore, if Figure 3 As shown, a plurality of placement slots 7 are provided on the first support plate 2, and the plurality of placement slots 7 are distributed in a circular array for placing sampling bottles. A working hole 9 is provided at the center of each placement slot 7, and the movable end of the electric push rod 8 slides through the working hole 9 to push the sampling bottle for sampling operation; wherein, the arrangement of the plurality of placement slots 7 can ensure the reasonable distribution of space between the sampling bottles, avoid mutual interference, and improve the sampling efficiency.

[0024] Furthermore, a guide sleeve 12 is movably connected to the placement groove 7. The guide sleeve 12 is used to ensure the vertical movement of the sampling bottle and fix the sampling bottle to prevent the sampling bottle from deviating from its position. The guide sleeve 12 can ensure that the sampling bottle always remains in a vertical state during the movement, avoiding the offset problem caused by water flow disturbance.

[0025] Furthermore, a transition hole 10 is provided on the second support plate 4, which is coaxial with the placement groove 7 for the bottle to pass through. The transition hole 10 allows the sampling bottle to smoothly pass through the second support plate 4 when moving upward, avoiding the occurrence of jamming.

[0026] Furthermore, the sealed cabin 13 is connected to the center of the first support plate 2 to protect the internal components, and the control components can be connected inside the sealed cabin 13. Figure 7As shown, a sealing cover 14 is connected to the top of the sealed chamber 13. A sealing ring is provided between the sealing cover 14 and the sealed chamber 13 to ensure the sealing performance of the sealed chamber 13. The provision of the sealed chamber 13 effectively prevents water from entering the internal component area, thereby improving the reliability and service life of the device. The sealing cover 14 is provided with a mounting slot 15 for connecting the sensor and the packing assembly.

[0027] Furthermore, the drive motor 5 is fixed above the second support plate 4 through a mounting base 11, and its output end is connected to the working baffle 6 for controlling the rotation of the working baffle 6. In addition, the mounting base 11 can enhance the stability of the drive motor 5, ensuring that the drive motor 5 will not affect the rotation accuracy of the working baffle 6 due to vibration during operation. The other end of the working baffle 6 is slidably connected to the working basket 1 and slides in the annular groove to press the sampling bottle and complete the closing operation. The sliding connection of the working baffle 6 enables it to be driven by the drive motor 5 to accurately rotate to just above the sampling bottle, thereby completing the closing operation of the sampling bottle. The electric push rod 8 is arranged at the bottom of the working basket 1 and is slidably penetrated into the working hole 9 to push the sampling bottle upward to cooperate with the closing operation of the sampling bottle.

[0028] It should be noted that, during operation, this sampling device is connected to the underside of the underwater robot. When the system controls the target sampling bottle to be powered on, the electric telescopic assembly in the sampling bottle pushes the middle rod, which drives the movable plate thereon outward, so that the boundary rod, under the action of the spring, pushes the bottle cap to open the sampling bottle for sampling. After sampling is completed, the electric push rod 8 reverses, and the middle rod returns to its original position. Subsequently, the electric push rod 8 pushes the sampling bottle upward, and the system controls the drive motor 5 to drive the working baffle 6 to rotate to directly above the sampling bottle. The combined action of the electric push rod 8 and the working baffle 6 presses the sampling bottle, completing the closing operation of the sampling bottle. When the underwater robot reaches the second sampling point, the second target sampling bottle is put into operation, and so on.

[0029] It should be noted that the sampling device provided by the embodiment of the present invention has at least the following advantages: (1) The present invention can complete the sampling work through system control by shore personnel, reducing the waste of manpower and material resources, reducing the serious waste of manpower and material resources caused by traditional monitoring methods, and improving the efficiency and practicality of underwater sampling work; (2) The present invention realizes continuous and efficient sampling of water bodies by carrying an underwater robot and cooperating with a sampling basket and a sampling bottle, and can independently complete underwater sampling tasks, solving the problem that the existing technology cannot collect water at a deeper depth and can only obtain a single point water sample in one sampling task, and cannot complete stratified sampling at different depths at one time; (3) The present invention can also realize real-time data collection of water samples in the water area while sampling, thereby ensuring the accuracy of the water sample data.

[0030] Example 2 Based on Example 1, this embodiment of the present invention provides a sampling device for an underwater robot. Specifically, a bottle is placed within a working basket 1, to which a filter and a cleaning assembly are connected. Two cleaning blocks intermittently move in a circular motion to clean the filter, preventing clogging. When the cleaning blocks stop moving, they vibrate, cooperating with the flowing water to shake off impurities such as sludge that may have contaminated their surfaces, achieving a self-cleaning effect.

[0031] Example 3 Based on Example 1, an embodiment of the present invention provides a sampling device serving an underwater robot. Specifically, the guide sleeve 12 is made of wear-resistant material, which can withstand the wear caused by multiple sampling operations and extend the service life of the device.

[0032] Example 4 Based on Example 1, an embodiment of the present invention provides a sampling device for an underwater robot. Specifically, a dynamic water flow compensation system is provided below the first support plate 2. The dynamic water flow compensation system includes a water flow sensor, a micro-hydraulic cylinder, and a compensation plate. The water flow sensor is mounted at the bottom of the working basket 1 to monitor the speed and direction of the water flow in real time. The micro-hydraulic cylinder is connected to the water flow sensor and is used to drive the compensation plate to adjust its angle. The compensation plate is connected to the bottom of the working basket 1 via a hinge to maintain the stability of the device under the impact of the water flow. When the water flow sensor detects a change in the water flow speed or direction, the micro-hydraulic cylinder adjusts the angle of the compensation plate based on the water flow data, thereby reducing the impact of the water flow on the sampling device and ensuring that the vertical movement of the bottle body is not disturbed during the sampling process.

[0033] Example 5 Based on Example 1, an embodiment of the present invention provides a sampling device for underwater robots. Specifically, a multi-stage water filtration assembly is added to the bottom of the working basket 1. The multi-stage water filtration assembly includes a coarse filter, a fine filter, and an activated carbon layer. The coarse filter is installed above the leak hole to intercept large particles of impurities; the fine filter is installed below the coarse filter to further filter small particles of impurities; and the activated carbon layer is installed below the fine filter to absorb organic pollutants in the water. When water enters the working basket 1 through the leak hole, the coarse filter, fine filter, and activated carbon layer sequentially filter and purify the water, ensuring the purity of the water during the sampling process.
