Description

Technical Field

[0001] The utility model relates to the technical field of ballast water sampling, in particular to a device for quickly sampling different depths of ship ballast water. Background Art

[0002] Ship's ballast water refers to the water added to a vessel to control its heel, trim, draft, stability, or stress. Ballast water contains organisms such as plankton, microorganisms, and bacteria, as well as fish eggs and larvae and spores of other plants. If discharged into a new environment with ballast water, these organisms could become invasive species and threaten the survival of other local species. Ballast water can also spread harmful parasites and pathogens. Therefore, customs are required to test the ballast water of foreign ships, and only discharge it into local waters if it passes the test.

[0003] Before testing ballast water, it is necessary to sample the ballast water in the ship. Existing sampling equipment cannot simultaneously sample at different depths in the ballast water. Ballast water at different depths must be taken out in batches, requiring multiple samplings. The operation is cumbersome and time-consuming, and it is also prone to cross-contamination of water samples, which in turn affects the accuracy of water sample test results. To this end, we provide a rapid sampling device for different depths of ship ballast water. Utility Model Content

[0008] Preferably, the bottom of the right side of the plug block is rotatably connected to the right side of the sampling tube via a hinge, and a slot is provided at the top of the right side of the plug block.

[0009] Preferably, a drain pipe is connected through the bottom of the left side of the inner wall of the water storage tank, and a drain valve is provided on the top of the drain pipe.

[0010] Preferably, the pusher includes two supports, which are fixed to the bottom of the right side of the sampling tube. A push plate is provided between the two supports, and the push plate is rotatably connected to the supports via a first rotating shaft.

[0014] (3) Beneficial effects

[0015] The utility model provides a device for rapid sampling of different depths of ship ballast water, which has the following beneficial effects:

[0016] 1. When the device is collecting water samples, first immerse the entire sampling tube in the ship's ballast water, then rotate the push plate to the right, and at the same time pull the rotating rod to the right. Since the bottom end of the rotating rod can be rotated between the two support blocks through the second rotating shaft, and the top end of the rotating rod can be rotated in the slot through the third rotating shaft, the rotating rod can pull the plug to the right to open the water inlet. Then, ballast water of different depths can enter the water storage bins of different heights through different water inlets for storage. In this way, ship ballast water samples of different depths can be taken out at the same time without the need for sampling in batches. The operation is simple, time-saving and labor-saving, and will not cause cross-infection of water samples, thereby ensuring the accuracy of water sample test results.

[0017] 2. When the device is sampling water, when the plug rotates to the right, the spring will be pulled by it and produce elastic deformation. After the sampling is completed, the rotating rod can be turned to the left. At this time, the pulling force disappears, the spring returns to its original shape and drives the plug to rotate to the left. The plug can block the water inlet again to seal the sampling tube.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] like Figure 1-6 As shown, the utility model provides a technical solution: a rapid sampling device for different depths of ship ballast water, including a sampling tube 1, the inner cavity of the sampling tube 1 is provided with multiple water storage bins 11 at equal distances from top to bottom, and a water inlet 12 is opened on the right side of the inner wall of the water storage bin 11. When sampling water, the ship's ballast water can be temporarily stored in the water inlet 12.

[0027] Among them, the inner cavity of the water inlet 12 is provided with a plug 3, and the bottom of the right side of the plug 3 is rotatably connected to the right side of the sampling tube 1 through a hinge. The plug 3 can be rotated open by the hinge to open the water inlet 12, and a slot 31 is provided at the top of the right side of the plug 3.

[0028] Furthermore, a push piece 6 is provided on the right side of the sampling tube 1. The push piece 6 includes two branches 61. The branches 61 are fixed to the bottom of the right side of the sampling tube 1. A push plate 62 is provided between the two branches 61. A grip 621 is provided on the top of the right side of the push plate 62. The push plate 62 and the branches 61 are rotatably connected through a first rotating shaft 63. A handle 2 is provided on the top of the sampling tube 1. When collecting water samples, the handle 2 and the grip 621 can be held by hand, and the sampling tube 1 can be immersed in the ballast water of the ship as a whole. Then, the push plate 62 can be rotated to the right through the first rotating shaft 63.

[0029] Furthermore, the plug block 3 and the push member 6 are rotatably connected via a rotating member 7. The rotating member 7 includes two support blocks 71. The support block 71 is fixed to the left side of the push plate 62. A rotating rod 72 is provided between the two support blocks 71. The rotating rod 72 and the support block 71 are rotatably connected via a second rotating shaft 73. The top of the rotating rod 72 is inserted into the inner cavity of the slot 31. The rotating rod 72 and the inner wall of the slot 31 are rotatably connected via a third rotating shaft 74.

[0030] During specific use, during sampling, when the push plate 62 rotates to the right, the rotating rod 72 can be pulled to the right. Since the bottom end of the rotating rod 72 can be rotated between the two support blocks 71 through the second rotating shaft 73, and the top end of the rotating rod 72 can be rotated in the slot 31 through the third rotating shaft 74, the rotating rod 72 can pull the plug block 3 to rotate to the right to open the water inlet 12, and then ballast water of different depths can enter the water storage tanks 11 at different heights through different water inlets 12 for storage. In this way, ship ballast water samples of different depths can be taken out at the same time without the need for sampling in batches. The operation is simple, time-saving and labor-saving, and will not cause cross-infection of water samples, thereby ensuring the accuracy of water sample detection results.

[0031] Furthermore, a bracket 4 is provided on the left side of the water inlet 12, and a spring 5 is connected between the left side of the plug 3 and the left side of the inner wall of the bracket 4. When the plug 3 rotates to the right, the spring 5 will be pulled by it and produce elastic deformation. After the sampling is completed, the rotating rod 72 can be rotated to the left. At this time, the pulling force disappears, the spring 5 returns to its original state and drives the plug 3 to rotate to the left. The plug 3 can block the water inlet 12 again to seal the sampling tube 1.

[0032] Furthermore, a drain pipe 8 is connected to the bottom of the left side of the inner wall of the water storage tank 11, and a drain valve 81 is provided on the top of the drain pipe 8. When testing the ballast water sample taken, the drain valve 81 can be opened, and the ballast water sample in the water storage tank 11 can be discharged from the drain pipe 8 and tested.
