[0039] The embodiments of the present utility model will be described in detail below with reference to the drawings.

[0040] Example:

[0041] See also Figure 1 、 Figure 2 and Figure 3 This embodiment discloses an automatic water sample collector, including a carrier 10, a shaft 20, a hose 30, a water pump 40 and a container 50, wherein the water pump 40, the container 50 and the shaft 20 are all arranged on the carrier 10, one end of the hose 30 is arranged on the shaft 20, and the other end passes through the carrier 10, the input end of the water pump 40 is connected to one end of the hose 30, and the output end of the water pump 40 is located above the container 50.

[0042] Specifically, the carrier 10 can float on the water surface, and a small hole 11 is provided in the middle of the carrier 10. The two ends of the shaft body 20 are rotatably arranged on the carrier 10 through a support member 21, and are close to the small hole 11. The interior of the shaft body 20 is a hollow structure. One end of the shaft body 20 is closed, and this end of the shaft body 20 is connected to the output shaft power of a first motor 22 to achieve control of the shaft body 20. The other end of the shaft body 20 is an open structure, and a connecting pipe 22 is connected to this end of the shaft body 20. The connecting pipe 22 passes through the support member 21 and is rotatably connected to the support member 21.

[0043] After passing through the support member 21, the connecting pipe 22 is rotatably connected to the input pipe of the water pump 40. A mechanical seal is generally provided here to prevent water leakage. The water pump 40 is mounted on the carrier 10 via a column, with a certain distance between the output end of the water pump 40 and the carrier 10. The container 50 is then placed within this distance, so that the container 50 can be located below the output end of the water pump 40.

[0044] One end of the hose 30 is connected to the shaft body 20 and communicates with the interior of the shaft body 20 . The hose 30 is then wrapped around the shaft body 20 , and the other end thereof passes through the small hole 11 on the carrier 10 .

[0045] The aforementioned container 50 may have a plurality of mutually isolated spaces therein, so as to contain samples from different locations in the water area.

[0046] During the working process, the carrier 10 transports the container 50, the water pump 40, and the hose 30 to different positions in the water area for sampling. During the sampling process, the first motor 22 drives the shaft body 20 to rotate, so that the hose 30 is lowered from the small hole 11 in the middle of the carrier 10. By controlling the number of rotations of the shaft body 20, the length of the lowered hose 30 is controlled, and further the depth of the sample collected in the water area is controlled. Combining with controlling the position of the carrier 10 in the water area, samples can be collected at different water surface positions and different depth positions in the water area. Compared with the prior art, this technical solution has a simpler structure and a more convenient control method.

[0047] In this technical solution, a control module can also be directly installed on the carrier 10, and the movement trajectory of the carrier 10 is remotely controlled by means of wireless signals, and the first motor 22 is controlled, and further the depth position of the hose 30 extending into the water surface is controlled.

[0048] In one specific embodiment:

[0049] The carrier 10 includes a plate body 12, an airbag 13, and a driving member 14. Among them, a plurality of airbags 13 are arranged on the circumference of the plate body 12, and the driving member 14 is arranged on the plate body 12.

[0050] Specifically, the plate body 12 is a square structure, generally made of wood or plastic. If it is made of plastic, the plastic is a hollow outer shell, and foam is filled inside it to reduce the density of the plate body 12. In addition, chamfers 15 are respectively made at the four corners of the plate body 12, and the driving member 14 is installed at the chamfer 15 of the plate body 12.

[0051] The aforementioned shaft body 20, water pump 40, and container 50 are all arranged on the plate body 12, and the small hole 11 on the carrier 10 is also located in the middle of the plate body 12.

[0052] Preferably, there are multiple driving members 14, and the number of driving members 14 is the same as the number of airbags 13, both being 4. The 4 airbags 13 are respectively arranged on the four sides of the plate body 12, and the airbag 13 is strip-shaped, and its length direction is the same as the length direction of the side of the plate body 12 where it is located. The 4 driving members 14 are respectively arranged at the four corners after the chamfer 15 of the plate body 12, and form a structure spaced one by one from the 4 airbags 13 and surround the plate body 12 for one week.

[0053] In this embodiment, the plate body 12 is used as the basis for installing the shaft body 20, the water pump 40, and the container 50. The carrier 10 can float on the water surface through the airbag 13. By controlling one or several of the driving members 14, the purpose of controlling the movement of the carrier 10 is achieved.

[0054] In another specific embodiment:

[0055] The driving member 14 includes a second motor 141 and a plurality of paddle boards 142. Among them, all the paddle boards 142 are fixedly installed on the output shaft of the second motor 141, and the length directions of all the paddle boards 142 are perpendicular to the output shaft of the second motor 141. In addition, all the paddle boards 142 are evenly distributed on the output shaft of the second motor 141.

[0056] Specifically, the second motor 141 is fixedly installed on the chamfer 15 of the plate body 12. After installation, the extension direction of the output shaft of the second motor 141 forms an angle of 45° with the adjacent sides on the plate body 12 and extends away from the plate body 12, so that all the paddle boards 142 are located outside the plate body 12.

[0057] In this embodiment, by controlling the motion states of the four second motors 141, different motion directions of the carrier 10 in the water area can be achieved.

[0058] In another specific embodiment:

[0059] The container 50 has an open structure. The bottom of the container 50 is slidably arranged on the carrier 10, and there are a plurality of mutually isolated troughs 51 inside the container 50. The output end of the water pump 40 is located above the container 50, so that the water sample output by the water pump 40 can be directly poured into the trough 51.

[0060] By changing the position of the container 50 on the carrier 10, the water sample output by the water pump 40 flowing into different troughs 51 can be changed. Combined with the driving of the first motor 22 on the shaft body 20 and the hose 30, and the driving of the driving member 14 on the carrier 10, it is possible to load the water samples at different positions in the water area into different troughs 51.

[0061] Preferably, the bottom of the container 50 has a threaded hole, and a screw rod 52 is fitted in the threaded hole. One end of the screw rod 52 is coaxially connected to the output shaft of a third motor 53. By designing the third motor 53 and the screw rod 52, the container 50 can be directly driven to slide on the carrier 10.

[0062] In another preferred solution, a base 54 is slidably arranged on the carrier 10. The top of the base 54 has a sunken hollow structure, and the container 50 can be placed in the hollow structure. Through this design, the container can be easily installed on the carrier 10 or easily removed from the carrier 10. And the aforementioned threaded hole is designed on the base 54, and the third motor 53 and the screw rod 52 drive the base 54 to move on the carrier 10, thereby driving the container 50.

[0063] In another specific embodiment:

[0064] On the top of the carrier 10, two containers 50, a base 54 and a screw rod 52 are symmetrically arranged and are respectively located on both sides of the shaft body 20. The two screw rods 52 are driven by the same third motor 53.

[0065] In addition, a tee pipe 41 is arranged at the output end of the water pump 40. One end of the tee pipe 41 is connected to the output shaft of the water pump 40, and the other two ends of the tee pipe 41 are respectively located above the two containers 50.

[0066] Through this embodiment, the amount of samples collected from the water area at one time can be increased, and at the same time, the weights on both sides of the carrier 10 can be balanced.

[0067] In another specific embodiment:

[0068] A counterweight 60 is arranged at one end of the hose 30 passing through the small hole 11. Through this counterweight 60, the hose 30 can move vertically into the water body.

[0069] In another specific embodiment:

[0070] A filter screen is arranged at one end of the hose 30 passing through the small hole 11. By designing the filter screen, sundries can be prevented from entering the hose 30, blocking the hose 30 or affecting the water pump 40.

[0071] The above embodiments only represent the specific implementation manners of the present utility model, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model.
