Description

Technical Field

[0001] This utility model relates to the field of water quality permeation sampling technology, specifically to a rotatable water quality permeation sampling device. Background Technology

[0002] Water infiltration sampling primarily targets groundwater, surface water, and specific water bodies (such as dialysis water) for sampling. Surface water includes rivers, lakes, and reservoirs. For surface water sampling, appropriate sampling points are typically selected based on the monitoring objectives and water body characteristics. Sampling points should be representative and accurately reflect the overall condition of the surface water. Surface water sampling is commonly used to assess the degree of water pollution, water quality trends, and to provide decision support for the rational utilization and protection of water resources.

[0003] For example, Chinese Patent Publication No. CN219265765U discloses a sampling device for groundwater detection. It is supported on the ground by a support frame, and an automatic sampling bucket is driven by a drive roller to descend into the groundwater. The sampling process is controlled wirelessly, allowing sampling to be performed regardless of water pressure, making operation more convenient and flexible, and facilitating groundwater sampling and detection. A waterproof battery powers a miniature waterproof electric actuator. The telescopic ends of the miniature waterproof electric actuator on both sides drive a piston plate to rise and fall. After the piston plate rises, groundwater passes through a filter plate into a conical cylinder, where impurities are filtered out. Then, the piston plate descends to seal the lower end of the conical cylinder's inner cavity, and the main body of the sampling bucket is retrieved, completing the sampling. However, this device can only sample the surface of the groundwater and cannot accurately sample based on the depth of the groundwater. Utility Model Content

[0031] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0032] Example 1:

[0033] Please see Figures 1-6 As shown, this utility model is a rotatable water quality permeation sampling device, characterized in that it includes a sampling bucket 1, which is used for collecting and storing water.

[0034] Water control component 4 is installed inside the sampling bucket 1 and is used to control the flow of water into and out of the sampling bucket 1.

[0035] It should be noted that the bottom of the sampling bucket 1 is equipped with a counterweight (not shown) to facilitate the sinking of the sampling bucket 1 into the groundwater.

[0036] In a preferred embodiment, the water control component 4 includes a bidirectional motor 400, which is fixedly connected to the gap of the end cap of the sampling bucket 1, and both output ends of the bidirectional motor 400 are fixedly connected to a drive shaft 401.

[0037] Bevel gear 403 is provided in two sets and is fixed to the middle of the end of the drive shaft 401 away from the bidirectional motor 400. Bevel gear 404 is meshed on one side of each bevel gear 403.

[0038] Screw 1 405, two sets of screw 1 405 are provided and both are fixed to the middle of bevel gear 2 404. A partition column 408 is fixed to one side of screw 1 405, and screw 2 409 is fixed to the side of partition column 408 away from screw 1 405.

[0039] Limiting plate 402, two sets of limiting plates 402 are provided and both are fixed to the gap of the end cap of sampling bucket 1.

[0040] It should be noted that the end cap of the sampling bucket 1 is hollow inside to facilitate the placement of the bidirectional motor 400 while preventing water from flowing in.

[0041] In a preferred embodiment, lead screw 405 and lead screw 409 are arranged oppositely. Lead screw 405, separator 408, and lead screw 409 are all movably installed in the sliding grooves opened on both sides of the sampling barrel 1, and the drive shaft 401 is movably installed in the middle of the limiting plate 402.

[0042] It should be noted that lead screw 1 405 and lead screw 2 409 enable relative movement between sliding block 1 406 and sliding block 2 410.

[0043] In a preferred embodiment, the water control component 4 also includes a sliding block 406, which is threadedly connected to the surface of the lead screw 405. The sliding block 406 slides through a groove opened inside the sampling barrel 1, and a connecting plate 407 is fixedly connected to one side of the sliding block 406.

[0044] Sliding block 2 410 is threadedly connected to lead screw 2 409. Sliding block 2 410 slides through a groove opened inside the sampling barrel 1. A retaining ring 411 is fixedly connected to one side of sliding block 2 410.

[0045] It should be noted that the connecting plate 407 is made of rubber, which makes the friction of the connecting plate 407 relatively large and generates a large suction force when it moves inside the sampling barrel 1. The sampling barrel 1 is a double-layered structure with an interlayer in the middle to facilitate the up and down movement of the retaining ring 411.

[0046] In the implementation process, the sampling bucket 1 is submerged to the required depth in the groundwater by a counterweight and a steel wire rope. A bidirectional motor 400 is installed, with both output ends of the bidirectional motor 400 rotating along the center of the limiting plate 402 with retaining rings 411. Each retaining ring 411 rotates a bevel gear 403, which in turn rotates a bevel gear 404. The bevel gear 404 then rotates a lead screw 405, a separator 408, and a lead screw 409 within the sampling bucket 1. The rotation of the lead screws 405 and 409 causes sliding blocks 406 and 410 to move simultaneously inward or outward along the lead screws 405 and 409, passing through the limiting position of the sampling bucket 1. Both block 406 and sliding block 410 move inward or outward simultaneously with connecting plate 407 and retaining ring 411. When both connecting plate 407 and retaining ring 411 move outward, connecting plate 407 moves upward, generating suction in sampling bucket 1 and drawing water at the depth of sampling bucket 1 into sampling bucket 1 through water hole 5. At the same time, retaining ring 411 moves downward. When connecting plate 407 moves to a fixed point, retaining ring 411 moves to water hole 5 and blocks water hole 5, preventing water from being exposed inside sampling bucket 1. When connecting plate 407 and retaining ring 411 move inward simultaneously, retaining ring 411 moves upward, leaving water hole 5 unobstructed, and connecting plate 407 moves downward, pushing water out through water hole 5.

[0047] Example 2:

[0048] In a preferred embodiment, the outer surface of the sampling bucket 1 is equipped with a connecting component 3, and the drainage funnel 2 is provided with four sets.

[0049] In a preferred embodiment, the connecting component 3 includes a fixing block 300, which is fixed to the outer surface of the sampling bucket 1. A connecting block 301 is slidably connected inside the fixing block 300, and a drainage funnel 2 is fixed to the side of the connecting block 301 away from the fixing block 300.

[0050] The connecting bolt 302 passes through the fixing block 300 and the connecting block 301 and is connected to the connecting nut 303 by threads.

[0051] It should be noted that the drainage funnel 2 is used when draining water inside the sampling bucket 1, but not when sampling bucket 1. A connecting hole is provided between its fixing block 300 and connecting block 301 to facilitate the passage of the connecting bolt 302.

[0052] As a preferred embodiment, the sampling bucket 1 is provided with four sets of water holes 5, which are arranged in a ring and a semi-permeable membrane is installed inside the water holes 5.

[0053] It should be noted that semipermeable membranes are existing technology. Semipermeable membranes allow solvent molecules to pass through, but prevent solute molecules (such as salts dissolved in water, organic matter, etc.) from passing through.

[0054] As a preferred embodiment, it also includes a connecting plate 6, a protective box 8 is fixedly connected to the bottom of the connecting plate 6, a drive motor 9 is fixedly connected inside the protective box 8, and the output end of the drive motor 9 is fixedly connected to the top of the sampling barrel 1. Two sets of positioning blocks 7 are fixedly connected to the top of the connecting plate 6.

[0055] It should be noted that the protective box 8 is made of waterproof material, which can effectively prevent the drive motor 9 inside the protective box 8 from being corroded by water flow. The positioning block 7 is provided with connection holes for easy connection with steel wire rope.

[0056] In the implementation process, the wire rope of the winch (not shown) is connected through the positioning block 7, so that the sampling bucket 1 can be controlled in terms of the depth of water placement. A drive motor 9 is set up, and the output end of the drive motor 9 drives the sampling bucket 1 to rotate. The rotation of the sampling bucket 1 can evenly collect the water around the sampling bucket 1. The drainage funnel 2 is connected to the fixing block 300 through the connecting block 301. The connecting bolt 302 is passed through the connecting block 301 and the fixing block 300 and then falls in through the connecting nut 303. When water is drained from the sampling bucket 1, it flows out through the water hole 5 and is guided downward by the drainage funnel 2. This can effectively drain the sampled water and prevent splashing and waste when the water in the sampling bucket 1 is discharged.

[0057] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
