[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in combination with the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0039] Refer to Figures 1 to 5, the present utility model protects a water quality sampling device, which includes a support member 1 that can be placed on a boat 4. The boat 4 refers to a small boat, such as a rowing boat or a small speedboat.

[0040] The top end of the support member 1 is hinged to a balancing member 3. The balancing member 3 can swing slightly relative to the support member 1 or sway slightly along the vertical direction, so that the plane where the balancing member 3 is located can be parallel to the water surface.

[0041] The support member 1 has at least two hanging ends, and each hanging end can be detachably connected to a sampling bottle 2. Each hanging end can take in and release a rope to make the sampling bottle 2 enter and exit the water for sampling.

[0042] The sampling bottle 2 can collect water samples on both sides simultaneously and store the water samples separately.

[0043] By setting the balancing member 3 in the present utility model, the balancing member 3 can swing slightly, so that the plane where the balancing member 3 is located is parallel to the water surface. In this way, the balancing member 3 etc. can offset part of the sway of the boat 4 and prevent the sampling depth of the sampling bottle 2 from being inaccurate due to the sway of the boat 4. Specifically, referring to Figure 1 for detailed description, when the boat 4 below sways, it will drive the support member 1 to sway. Since the balancing member 3 is hinged to the support member 1, the influence on the balancing member 3 is relatively small. Of course, the balancing member 3 can only offset the vertical sway of the boat 4 to a certain extent, try to make the sampling bottle 2 sample at the specified depth and reduce the influence. It cannot completely avoid the influence of the boat 4.

[0044] By setting the sampling bottle 2, the sampling bottle 2 can collect water samples on both sides simultaneously, and can collect water samples from the same layer, preventing the interference of water samples from the upper and lower layers; in addition, the sampling bottle 2 can store the water samples on both sides separately, so that multi-point sampling at the same position can be realized, ensuring the accuracy of the sampling result.

[0045] Referring to Figure 3 , in a specific embodiment, the sampling bottle 2 includes a bottle body 21 and a bottle cap 23 detachably connected to the top end of the bottle body 21. A vertical partition 29 is provided in the bottle body 21, which can divide the bottle body 21 into two left and right accommodating spaces. Two water inlet pipes 22 are provided on the side wall of the bottle body 21, and the two water inlet pipes 22 are respectively communicated with the two accommodating spaces. Each water inlet pipe 22 can be independently controlled to open and close to realize water inlet. Among them, the water inlet pipe 22 is perpendicular to the side wall of the bottle body 21, and the water inlet pipes 22 are oppositely arranged on both sides of the bottle body 21.

[0046] In this embodiment, the water inlet pipe 22 is set to take water samples. In this way, the water inlets of the two water inlet pipes 22 will not interfere with each other. Moreover, the water inlet pipe 22 can take in water in the horizontal direction, minimizing the interference of upper and lower layer waters to the greatest extent. By making the bottle body 21 and the bottle cap 23 detachably connected, when detecting the water sample in the sampling bottle 2, the bottle cap 23 can be opened to detect the water samples on both sides of the partition plate 29. It is also possible to open the bottle cap 23, pour out and mix the water sample in the bottle body 21 before detection.

[0047] Reference Figure 3 , in a specific embodiment, a screw rod 25 is provided inside the water inlet pipe 22. The axis of the screw rod 25 coincides with the axis of the water inlet pipe 22. A gear cover 26 is provided at the outer end of the screw rod 25. One end of the screw rod 25 is a cross end, and the cross end is fixed on the inner wall of the water inlet pipe 22. The other end of the screw rod 25 protrudes from the water inlet end face of the water inlet pipe 22. The gear cover 26 is a conventional gear with a threaded hole opened in the center. The screw rod 25 passes through the threaded hole, enabling the gear cover 26 to rotate, approaching or moving away from the water inlet pipe 22, so as to close or open the water inlet pipe 22. A sealing gasket can also be provided on the side of the gear cover 26 close to the water inlet pipe 22 to ensure the sealing performance, prevent the water sample from leaking out, and of course also prevent the water samples of other layers from entering.

[0048] A wireless motor 28 is provided on the side wall of the bottle body 21. One end of the rotating shaft of the wireless motor 28 is connected to a driving gear 27, and the driving gear 27 meshes with the gear cover 26. The wireless motor 28 is a commercially available waterproof motor.

[0049] The wireless motor 28 can drive the driving gear 27 to rotate forward and backward, so that the gear cover 26 approaches or moves away from the water inlet of the water inlet pipe 22.

[0050] In this embodiment, by providing the screw rod 25 and the gear cover 26, when taking water samples, the gear cover 26 can move horizontally in a spiral manner, which can reduce the fluctuation of the water layer and the influence of waters of different layers, ensuring that the taken water sample can truly reflect the actual situation of the water body, improving the representativeness of the water sample and the accuracy of the detection result.

[0051] Reference Figure 3 , in a specific embodiment, a lifting ring 24 is provided on the top surface of the bottle cap 23. The lifting ring 24 is convenient for detachably connecting with a rope. In addition, after the sampling bottle 2 takes the water sample from the water, a label can be hung on the lifting ring 24 to distinguish the sampling bottles 2 at different sampling positions.

[0052] Reference Figure 2 , in a specific embodiment, the support member 1 includes a support column 12, and at least 3 legs 11 are provided at the bottom end of the support column 12. The top end of the support column 12 is connected to a sphere 13 through a support rod 14. Among them, the diameter of the support column 12 is larger than the diameter of the support rod 14.

[0053] In this embodiment, a plurality of legs 11 are provided so that the support member 1 can be placed at different positions of the ship, increasing the stability. By arranging the support column 12 below, the overall center of gravity of the support member 1 is biased downward, further increasing the stability of the support member 1.

[0054] Reference Figure 4 and Figure 5 , in a specific embodiment, the balance member 3 includes a cross-shaped frame body 31. The frame body 31 can be formed by vertically intersecting two straight rods of the same length, or can be formed by splicing four straight rods of the same length.

[0055] A ball socket 33 is provided at the midpoint of the bottom surface of the frame body 31, and the ball socket 33 is sleeved on the outer side of the top of the sphere 13.

[0056] The frame body 31 has 4 ends, and the suspension end is the end.

[0057] A winch 35 and a drive motor 34 for driving the winch 35 to rotate are provided on each end, and a rope is provided in the winch 35.

[0058] In this embodiment, by providing the frame body 31, the frame body 31 has 4 ends on the horizontal plane, and the 4 ends have different positions, so that multiple water samples can be taken at the same depth at one sampling point for the sampling bottle 2, and the error can be reduced.

[0059] Reference Figure 3 and Figure 4 , in a specific embodiment, the ball socket 33 includes a hollow hemispherical sleeve body 331, and a plurality of convex blocks 332 are provided at the edge of the sleeve body 331, and the convex blocks 332 can limit the swinging amplitude of the frame body 31.

[0060] In this embodiment, by providing the convex blocks 332, the swinging amplitude of the frame body 31 can be limited. In this way, when the ship 4 is traveling fast when sampling work is not carried out, the frame body 31 swings within a controllable range to prevent hitting the staff; in addition, by providing the convex blocks 332, limiting can be carried out. For example Figure 4 In, only the leftmost sampling bottle 2 is used for sampling, and the rest of the sampling bottles 2 are not sampled. The leftmost sampling bottle 2 will pull the frame body 31 to deviate downward, and the convex blocks 332 can prevent the frame body 31 from deviating excessively.

[0061] Reference Figure 3 and Figure 4 , in a specific embodiment, 4 counterweights 32 are uniformly arranged on the frame body 31, and the distance from each counterweight 32 to the center of the frame body 31 is the same. Among them, the counterweight 32 is a cuboid, and the bottom end of the cuboid is lower than the lowermost end of the sphere 13. In this way, the center of gravity of the frame body 31 can be lower than the connection point between the support member 1 and the balance member 3, enabling the frame body 31 to automatically maintain balance, and the plane where the frame body 31 is located can be as parallel to the water surface as possible, so that the sampling bottles 2 at the ends of the frame body 31 have the same underwater depth.

[0062] The above-disclosed are only the preferred embodiments of the present utility model. Of course, the scope of rights of the present utility model cannot be limited thereby. Therefore, equivalent changes made according to the claims of the present utility model still fall within the scope covered by the present utility model.
