[0002] In the field of natural water sample collection, conventional sampling devices often have a single function and are unable to meet diverse sampling needs. Many water bodies have complex environments and may need to collect both whole water samples containing large suspended particles or organisms and relatively clear water samples that have been filtered out of large impurities for analysis.

[0003] Traditional methods usually require carrying two different samplers or replacing filter components on site, which is cumbersome and inefficient, and increases equipment costs and carrying burdens. In addition, floating objects on the water surface can easily clog the sampling port, resulting in slow water inflow or sampling failure. After sampling, the sample is prone to stratification or sedimentation, affecting the representativeness of the detection. Therefore, a natural water sample sampler is provided to solve the above problems. Summary of the Invention

DETAILED DESCRIPTION

[0026] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0027] like Figure 1-5 As shown, a natural water sample sampler of the present invention includes a sampling tank 1 and an electric rotating base 2. The electric rotating base 2 is a relatively existing mechanical device, which is generally composed of a control panel and a motor. Its external power supply can drive the output end to rotate through the motor. A water sampling groove 11 is opened at the upper end of the sampling tank 1, an adjustment mechanism is provided on the upper side of the sampling tank 1, and a mixing mechanism is installed on the lower side of the sampling tank 1.

[0028] The sampling slots 11 are two circumferentially symmetrical fan-shaped slots;

[0029] The circumferentially symmetrical fan-shaped grooves are easy to rotate and adjust, so that two different sampling states can be quickly adjusted;

[0030] The adjustment mechanism includes a fan-shaped filter 12. The upper side of the sampling tank 1 is sealed and rotated with two circumferentially symmetrical fan-shaped filter screens 12. The upper end of the sampling tank 1 is equipped with a damping rotation knob 13. The two fan-shaped filter screens 12 are fixedly connected to the lower end of the knob 13.

[0031] When the knob 13 of the damping rotation assembly is not adjusted, the knob 13 which is not affected by external forces will not rotate on its own, thereby avoiding switching between different sampling states;

[0032] The mixing mechanism includes a mixing fan blade 14, which is sealed and rotatably assembled on the lower side of the sampling tank 1. The lower end of the sampling tank 1 is rotatably assembled with a concave connecting piece 141. The upper side of the concave connecting piece 141 is transmission-connected to the lower side of the mixing fan blade 14. The rotating end of the electric rotating base 2 is fixedly assembled with a convex connecting piece 21, and the concave connecting piece 141 matches the convex connecting piece 21.

[0033] The concave connecting piece 141 matches the convex connecting piece 21 in shape. After the two are connected to each other, the mixing blades 14 can be driven by the electric rotating base 2 to rotate and mix the sampled liquid.

[0034] The upper side of the sampling tank 1 is provided with a plurality of circumferentially symmetrical side grooves 15. A plurality of circumferentially symmetrical side screens 16 are fixedly mounted on the lower side of the fan-shaped filter 12. The side screens 16 are rotatably connected to the inner side of the sampling tank 1. The side grooves 15 and side screens 16 increase the efficiency of side water inflow, preventing the fan-shaped filter 12 at the top from being clogged by floating objects on the water surface, which would reduce the efficiency of water inflow to the sampling tank 1.

[0035] The edges of the water intake trough 11 and the side troughs 15 are provided with inclined scraping strips 17 , and the outer surfaces of the side filter screens 16 and the outer surfaces of the two sector-shaped filter screens 12 are matched with the inclined scraping strips 17 corresponding to their positions.

[0036] During the rotation of the knob 13, the surfaces of the sector filter 12 and the side filter 16 can be cleaned by tilting the scraper 17, thus reducing the cleaning effort of the staff.

[0037] A damping friction pad 131 is fixedly provided at the lower end of the knob 13 , and a plurality of evenly distributed friction strips 132 are fixedly provided at the side of the knob 13 .

[0038] A carrying ring 31 is fixedly provided at the lower end of the sampling tank 1 , and a sealing cover 32 is rotatably assembled on the outer side of the carrying ring 31 through a sealing thread.

[0039] The sealing cover 32 is a weighted cover that can keep the center of gravity of the sampling tank 1 at the bottom, preventing the sampling tank 1 from tilting after sampling and causing the sampled liquid to spill.

[0040] A servo motor is assembled inside the electric rotating base 2 , and an output end of the servo motor is transmission-connected to the convex coupling member 21 .

[0041] A transparent window 33 is provided on the side of the sampling tank 1, and a scale line 34 is fixed on the side of the sampling tank 1. The scale line 34 is assembled on the side of the transparent window 33. The transparent window 33 allows the staff to observe the state of the sampled liquid inside the sampling tank 1, and the scale line 34 allows the sampler to take out a specified amount of liquid.

[0042] When using this device to sample liquid, the staff first turns the knob 13 to adjust the sampling state: when the knob 13 is turned to the first position, the water trough 11 and the side trough 15 are directly opened, allowing the liquid to directly enter the sampling tank 1 for sampling; when the knob 13 is turned to the second position, the fan-shaped filter 12 covers the water trough 11, and the side filter 16 covers the side trough 15, and large impurities are filtered and sampled through the side filter 16 and the fan-shaped filter 12. Subsequently, the sampling tank 1 is immersed in a natural water body, and the liquid flows into the interior of the sampling tank 1 through the water intake trough 11 or the side trough 15, and the sampling is completed at this time; when the liquid inside the sampling tank 1 needs to be used, the sampling tank 1 is taken out, and then the concave connector 141 at the lower end of the sampling tank 1 is connected with the convex connector 21 of the electric rotating base 2, and the electric rotating base 2 is started to drive the mixing fan 14 to rotate to mix the liquid inside the sampling tank 1. After the mixing is completed, the sampling personnel can perform partial sampling and testing on the liquid.

[0043] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed herein are intended to be covered by the claims of the present invention.
