DETAILED DESCRIPTION

[0013] The utility model will be further described below in conjunction with the accompanying drawings.

[0014] Please refer to Figure 1-4 The utility model is a ship ballast water sampler for microbial detection, comprising a sampling tube 1, both ends of the sampling tube 1 away from each other are fixedly connected with flanges 5, a bottom groove 2 is provided on the bottom side wall of the sampling tube 1 and near the middle position, a storage groove 7 is provided on the bottom side wall of the sampling tube 1 and near the bottom groove 2, two rotating columns 6 are rotatably connected between the bottom groove 2 and the water intake pipe 3, the water intake pipe 3 is fixedly connected between the two rotating columns 6, the water intake pipe 3 is a cylindrical structure, a section of the inner wall of the water intake pipe 3 located in the sampling tube 1 is fixedly connected with a convex plate 12, a blocking column 13 is set between the convex plates 12, and a control rod 4 is fixedly connected to the middle of the bottom side wall of the blocking column 13;

[0015] A cross plate 20 is fixedly connected to one end of the water intake pipe 3 located in the bottom groove 2, a screw groove 14 is opened in the middle of the cross plate 20, the control rod 4 is inserted and connected in the screw groove 14, and a section of the outer wall of the control rod 4 located above the screw groove 14 is fixed with threaded teeth 15, and the control rod 4 is threadedly connected to the screw groove 14 through the threaded teeth 15.

[0016] As a preferred technical effect of the present scheme, since the sampling tube 1 is installed on the water outlet end of the filter, the filtered ballast water can be sampled, avoiding the problem of inaccurate detection conclusions caused by sampling the water in the ballast water tank. The end of the water intake pipe 3 located in the bottom groove 2 is moved to rotate the water intake pipe 3 along the rotating column 6, and the end of the water intake pipe 3 located in the storage groove 7 is tilted, so that the end of the water intake pipe 3 located in the sampling tube 1 impacts the flowing water. This state allows the ballast water to enter the water intake pipe 3 more smoothly, thereby improving the efficiency and quality of sampling.

[0017] A water inlet 8 is provided on the side wall of the water intake pipe 3 located above the blocking column 13, and a sealing plate 9 is inserted in the water inlet 8. A movable groove 10 is provided on the side wall of the sampling tube 1 located below the water inlet 8, and a linkage rod 11 is telescopically inserted in the movable groove 10. One end of the sealing plate 9 extends into the movable groove 10 and is fixedly connected to one end of the linkage rod 11. The end of the linkage rod 11 away from the sealing plate 9 extends out from the bottom opening of the movable groove 10. The side wall of the end of the linkage rod 11 away from the sealing plate 9 is rotatably connected to a positioning plate 16 through a torsion spring. The side wall of the movable groove 10 opposite to the positioning plate 16 is fixedly connected to a limiting plate 17. The positioning plate 16 is an outwardly inclined structure, and the limiting plate 17 is a hook-shaped structure opposite to the positioning plate 16. The bottom side wall of the positioning plate 16 is rotatably connected to a rotating shaft 18, and the bottom side wall of the rotating shaft 18 is fixedly connected to an adjusting column 19, and the end of the adjusting column 19 away from the rotating shaft 18 extends out from the bottom opening of the movable groove 10.

[0018] As a preferred technical effect of this solution, the linkage rod 11 is pulled downward to pull the sealing plate 9 into the movable groove 10, so that the water inlet 8 is in an open state, and the water that impacts the water intake pipe 3 will enter the water intake pipe 3 through the open water inlet 8. The blocking column 13 is pushed upward in advance, so that the water entering the water intake pipe 3 can flow out from the gap between the blocking column 13 and the convex plate 12, and finally the water flows along the water intake pipe 3 into the pre-prepared sample tube, so that the ballast water can be sampled without stopping the machine.

[0019] Specifically, when the utility model is used, in order to ensure the stability of the fit between the blocking column 13 and the convex plate 12, a transverse plate 20 is set up and a screw groove 14 is opened in the middle of the transverse plate 20, and at the same time, the threaded teeth 15 are connected to the control rod 4, and the blocking column 13 is pulled down and the threaded teeth 15 are inserted into the screw groove 14, and then the threaded teeth 15 are rotated to make it threadedly connected into the screw groove 14. Due to the characteristics of the threaded connection, the blocking column 13 is also pulled down synchronously during the rotation process, thereby increasing the tightness of the fit between the blocking column 13 and the convex plate 12, and preventing the ballast water from leaking out when sampling is not performed. When sampling, it is only necessary to reverse the control rod 4 to push open the blocking column 13, and then pull the sealing plate 9 into the movable groove 10 to achieve water inlet and sampling. The positioning plate 16 is provided to ensure stable blocking of the sealing plate 9 and the water inlet 8. When the linkage rod 11 is pushed upward, the positioning plate 16 is pressed toward the linkage rod 11 by the limiting plate 17. When the linkage rod 11 moves to above the limiting plate 17, it will open outward under the action of the torsion spring. Then the bottom end of the positioning plate 16 will be inserted into the bottom end of the limiting plate 17 to realize the positioning of the linkage rod 11. When the water inlet 8 needs to be opened, the linkage rod 11 is pushed upward to disengage the positioning plate 16 from the limiting plate 17. Then the adjusting column 19 is pulled to adjust the positioning plate 16 toward the direction of the linkage rod 11. Then, the linkage rod 11 and the adjusting column 19 are pulled downward synchronously to pull the sealing plate 9 into the movable groove 10.

[0020] The above are only preferred implementations of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.

[0021] Other parts of the present invention not described in detail belong to the prior art and will not be described in detail here.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
