Abstract
Description
Technical Field
[0001] This utility model relates to the field of marine environmental monitoring technology, specifically a filtering sampling device for marine environmental monitoring. Background Technology
[0002] The marine environment refers to the vast, continuous body of water of the oceans and seas on Earth, including seawater, dissolved and suspended substances in seawater, seabed sediments, and marine life. It is the cradle of life and a treasure trove of resources for humankind. With the increasing scale of human exploitation of marine resources, it has been impacted and polluted by human activities. To protect the marine environment, monitoring is necessary.
[0003] The main function of marine environmental monitoring sample collection equipment is to obtain a certain amount of seawater, sediment, or biological samples for subsequent monitoring and analysis, facilitating the understanding of the degree of pollution in the marine environment. When conducting marine environmental monitoring, the primary task is seawater sample collection. To ensure the accuracy of seawater testing, staff need to collect samples from different stations in the ocean. During seawater sampling, the device is directly inserted into the water, allowing seawater to automatically fill in. Floating debris such as garbage in the seawater will also enter the sampling device. Directly emptying the sample will result in the loss of some water sample, while emptying too much will render the sample unsuitable for testing. Utility Model Content

Detailed Implementation
[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] like Figures 1 to 3As shown in this embodiment, a filtering sampling device for marine environmental monitoring is disclosed, including a column 1. A sampling bucket 2 is provided on one side of the column 1. One side of the sampling bucket 2 is connected to the column 1 via a lifting assembly 3. The lifting assembly 3 includes a lifting motor 31, a driving gear 32, and a driven gear 33. The interior of the column 1 is a cavity. The lifting motor 31 is fixedly connected to the column 1 via a fixing plate 34. The lifting motor 31 is located below the cover opening assembly 5. The output shaft of the lifting motor 31 is fixedly mounted with the driving gear 32. The driving gear 32 meshes with the driven gear 33. The driving gear 32 and the driven gear 33 are rotatably arranged inside the column. Racks 35 are meshed on the outer sides of both the driving gear 32 and the driven gear 33. Slide grooves 36 are opened on both the front and rear sides of the interior of the column 1. The top surface of the column 1 is an opening. A slider 37 is slidably arranged in the slide groove 36. The slider 37 and the driven gear 33 are connected to each other. The corresponding racks 35 are fixedly connected. Vertical grooves 38 are opened on both the front and rear sides of one side of the column 1. The vertical grooves 38 are connected to the corresponding sliding grooves 36. Sliding rods 39 are slidably installed in the vertical grooves 38. A connecting frame 310 is fixedly installed at one end of the two sliding rods 39. The connecting frame 310 is fixedly connected to the sampling bucket 2. The lifting motor 31 works. The output shaft of the lifting motor 31 drives the driven gear 33 to rotate through the driving gear 32. The driving gear 32 and the driven gear 33 can drive the corresponding racks 35 to move up and down, and can drive the slider 37 to move in the sliding groove 36. The slider 37 slides in the vertical groove 38 through the sliding rods 39, which can drive the connecting frame 310 to move up and down. Thus, the connecting frame 310 can drive the sampling bucket to move up and down, and can adjust the height of the sampling bucket, so that it can be used for sampling in marine environments at different depths.
[0018] The top surface of one side of the sampling bucket 2 is rotatably connected to the bucket lid 4 via a spring shaft. The upper end of the column 1 is connected to the bucket lid 4 via a lid opening assembly 5. The lid opening assembly 5 includes a lid opening motor 51, a reel 52, and a rope 53. The lid opening motor 51 is fixedly installed on the top surface of the fixing plate 34. The output shaft of the lid opening motor 51 is fixedly installed on the reel 52. The reel 52 is rotatably installed inside the column 1. The upper end of the rope 53 is fixedly connected to the reel 52. A through groove 54 is opened on one side of the upper part of the column 1. The lower end of the rope 53 passes through the through groove 54. The top of the bucket lid 4... A connecting ring 55 is fixedly installed on one side of the sample container. The lower end of the rope 53 is fixedly connected to the connecting ring 55. The reel 52 is located in the middle of the two racks 35. When the opening motor 51 is working, the output shaft of the opening motor 51 drives the reel 52 to rotate. When the reel 52 is winding the rope 53, the rope 53 can open the lid 4, allowing seawater to enter the sampling container 2 and thus complete the water collection. When the reel 52 is releasing the rope, the lid 4 can be reset under the action of the spring shaft, thus closing the lid 4.
[0019] A filter assembly 6 is installed inside the sampling bucket 2. The filter assembly 6 includes a V-shaped filter cover 61, a moving block 62, and a vertical rod 63. The vertical rod 63 passes through the middle of the V-shaped filter cover 61 and is rotatably connected to the V-shaped filter cover 61. Moving blocks 62 are fixedly installed on both sides of the V-shaped filter cover 61. Moving grooves 64 are opened on both sides inside the sampling bucket 2. The moving blocks 62 are slidably set in the corresponding moving grooves 64. The lower end of the vertical rod 63 has an external thread. A screw hole 65 is opened on the bottom surface inside the sampling bucket 2. The lower end of the vertical rod 63 is threaded to the screw hole 65. The V-shaped filter cover 61 filters marine debris, thereby effectively preventing marine debris from entering the sampled seawater during seawater sampling and causing deviations in the test results. When the vertical rod 63 is rotated, the lower end of the vertical rod 63 moves out of the screw hole 65, allowing the V-shaped filter cover 61 to be removed from the sampling bucket 2. This allows the marine debris inside the V-shaped filter cover 61 to be removed and facilitates the replacement of the V-shaped filter cover 61.
[0020] A counterweight 66 is provided at the lower end of the vertical rod 63. When the threaded connection between the lower end of the vertical rod 63 and the screw hole 65 fails, the counterweight 66 can keep the V-shaped filter cover 61 inside the sampling bucket 2, preventing the filter cover 61 from floating out of the sampling bucket 2 and thus making it impossible to filter the collected seawater.
[0021] A drain pipe 7 with a valve is installed on the lower side of the other side of the sampling bucket 2. The water in the sampling bucket 2 can be drained through the drain pipe 7, so that it can be used in the next step.
[0022] Working principle:
[0023] When the lifting motor 31 operates, its output shaft drives the driven gear 33 to rotate via the driving gear 32. The driving gear 32 and driven gear 33 drive the corresponding rack 35 to move up and down, which in turn moves the slider 37 within the slide groove 36. The slider 37 slides within the vertical groove 38 via the slide rod 39, which in turn moves the connecting frame 310 up and down. This allows the connecting frame 310 to move the sampling bucket up and down, adjusting its height to accommodate sampling in marine environments at different depths. When the cover-opening motor 51 operates, its output shaft drives the reel 52 to rotate. When the reel 52 is winding, the rope 53 winds around it, simultaneously opening the lid 4 and allowing seawater to enter the sampling bucket 2, thus completing the water collection. When the reel 52 releases the line, the spring shaft causes the lid 4 to reset, thus closing the lid 4. The V-shaped filter 61 filters marine debris, effectively preventing marine debris from entering the seawater sample during seawater sampling and causing deviations in the test results. Rotating the vertical rod 63 moves the lower end of the vertical rod 63 out of the screw hole 65, allowing the V-shaped filter 61 to be removed from the sampling bucket 2, thus removing the marine debris inside the V-shaped filter 61 and facilitating its replacement. When the threaded connection between the lower end of the vertical rod 63 and the screw hole 65 fails, the weight block 66 keeps the V-shaped filter 61 inside the sampling bucket 2, preventing the filter 61 from floating out of the sampling bucket 2 and thus failing to filter the collected seawater.
