Description

Technical Field

[0001] The utility model relates to the technical field of environmental detection equipment, in particular to a water quality environmental monitoring and sampling device. Background Technique

[0002] When water quality monitors sample the water environment, they not only need to collect shallow water but also deep water. Shallow water can be collected with an ordinary collection bottle. Since deep water passes through shallow water, when sampling, it is necessary to first close the collection port and then open the collection port after reaching the deep layer for water body sampling.

[0003] After retrieval, a water quality sampler with the Chinese patent publication number CN218629097U, which relates to the technical field of collectors, includes a collection bottle. An activity chamber and a sample chamber are provided on the collection bottle. Two first water inlets are opened on the sample chamber. Two baffles are provided in the collection bottle. Telescopic rods are installed at the bottom sides of the two baffles. A sealing ring is installed on the two telescopic rods. A movable base is sleeved on the sealing ring.

[0004] This sampler can meet the need of closing the sampling port at the shallow layer first and then opening the sampling port at the deep layer for sampling. However, the depths of the deep layers of different water bodies are different, and this kind of collector cannot freely adjust the height at which the sampling port is opened after the collector sinks into the water. Therefore, it needs to be improved.

[0005] Therefore, we propose a water quality environmental detection and sampling device. Content of the Utility Model

[0017] (1) For this water quality environment detection and sampling device, the sampling bin is used to collect deep water bodies.

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope protected by the present utility model.

[0028] Embodiment: A water quality environment detection sampling device, as Figures 1-4As shown in the figure, it includes a sampling cylinder 1. The sampling cylinder 1 is a hollow tank. Inside the sampling cylinder 1, a middle partition 2 is integrally formed. The middle partition 2 divides the interior of the sampling cylinder 1 into upper and lower parts to form a sampling chamber 3 and an adjustment chamber 4. Among them, the sampling chamber 3 is used to collect deep water bodies, and the structure inside the adjustment chamber 4 is used to control the sinking and floating speed of the sampling cylinder 1 in water, and to control at what depth in the water the sampling cylinder 1 conducts sampling.

[0029] Specifically, an airbag 5 is fixedly installed at the upper end inside the adjustment chamber 4. The output end of the airbag 5 is fixedly installed with a one-way valve 6. The one-way valve 6 penetrates through the top of the sampling cylinder 1. During use, the airbag 5 is filled with gas to increase the buoyancy of the sampling cylinder 1 in water. When the airbag 5 gradually discharges air during use, the buoyancy weakens and it sinks into the water. The one-way valve 6 is an existing interface. When it is opened, the gas in the airbag 5 can only be discharged outward, and water cannot flow back from here, and it can control the flow rate of the gas discharge.

[0030] Among them, an adjustment water inlet 9 communicating with the adjustment chamber 4 is opened on the side wall of the sampling cylinder 1 corresponding to the bottom of the adjustment chamber 4. A depth partition 7 that can slide up and down in the adjustment chamber 4 is movably installed inside the adjustment chamber 4 at a position corresponding to below the airbag 5. When the sampling cylinder 1 is placed in water, water flows into the adjustment chamber 4 from the depth rod 8, pushes the depth partition 7 from below to squeeze the airbag 5, and discharges air. Further, a depth rod 8 is also movably installed inside the adjustment chamber 4. The depth rod 8 penetrates through the outer wall of the sampling cylinder 1 and extends into the adjustment chamber 4, and a push switch is provided at the bottom end surface of the depth rod 8. By adjusting the length of the depth rod 8 extending into the adjustment chamber 4, it is controlled where the depth partition 7 is squeezed to trigger the switch below the depth rod 8, and by controlling the speed of water flowing into the adjustment chamber 4, it is controlled when the sampling cylinder 1 collects water in the water.

[0031] Specifically, a sampling port 10 is opened on the outer wall of the sampling cylinder 1 corresponding to the upper part of the sampling chamber 3. When collecting water, water flows into the sampling chamber 3 from here. A central axis 11 is fixedly installed on the side wall of the sampling cylinder 1. Two shear rods 12 are movably installed on the central axis 11. The two shear rods 12 are movably connected in an X shape on the central axis 11. Sealing baffles 13 are fixedly installed at one end of the two shear rods 12 close to the sampling port 10. When the two sealing baffles 13 are combined, they block the sampling port 10, thereby closing the sampling port 10 and preventing water from entering the sampling chamber 3.

[0032] Further, one end of a set of shearing rods 12 close to the sampling port 10 is fixedly installed with an opening spring 14. The opening spring 14 is an elastic spring. Under the action of the elastic force of the opening spring 14, the two sealing baffles 13 always remain in an open state. The upper end face of the sampling cylinder 1 is also fixedly installed with an electric telescopic rod 15. The electric telescopic rod 15 is electrically connected to the pressing switch below the depth rod 8. The output end of the electric telescopic rod 15 is fixedly installed with a gathering frame 16. A groove for accommodating the ends of the two sets of shearing rods 12 is opened below the gathering frame 16. The ends of the two sets of shearing rods 12 are gathered by the gathering frame 16, so that the end of the shearing rod 12 close to the sampling port 10 overcomes the elastic force of the opening spring 14 and merges, blocking the sampling port 10. When the electric telescopic rod 15 is opened, the gathering frame 16 retracts, thus no longer restricting the shearing rod 12, and then the sealing baffle 13 is opened, allowing water to enter the sampling port 10.

[0033] Further, a slide rail 17 is fixedly installed in the sampling chamber 3. A buoyancy block 18 that can slide up and down along the slide rail 17 is movably installed in the middle of the slide rail 17. The buoyancy block 18 is hollow inside and has buoyancy. An inner sealing plate 19 is fixedly installed at the upper end of the buoyancy block 18. The inner sealing plate 19 is a rectangular block. During sampling, water flows into the sampling chamber 3, causing the buoyancy block 18 to float along the slide rail 17. Finally, the inner sealing plate 19 seals the sampling port 10 inside, preventing external water from entering the sampling chamber 3.

[0034] Further, a magnetic block 20 is fixedly installed at the top end of the slide rail 17. The magnetic block 20 is magnetically connected to the inner sealing plate 19. When the buoyancy block 18 floats near the top end of the slide rail 17, under the action of magnetic force, the inner sealing plate 19 immediately lifts up to block the entire sampling port 10, and at the same time, the sealing degree of the sampling port 10 is strengthened.

[0035] Further, the sampling cylinder 1 has a cylindrical structure and the side where the sampling port 10 is opened is a plane. At the same time, a slidable and openable sliding filter screen 21 is fixedly installed on the side wall surface of the sampling cylinder 1 corresponding to the sampling port 10. The sliding filter screen 21 and the sampling cylinder 1 form a complete arc surface, so as to filter debris and facilitate cleaning when collecting water.

[0036] Further, a handle 22 is fixedly installed at the top end of the sampling cylinder 1, which is convenient for carrying and tying ropes.

[0037] Working principle of the utility model: When in use, close the one-way valve 6, fill the airbag 5 with gas, adjust the length of the depth rod 8 extending into the adjustment chamber 4, then adjust the one-way valve 6 to the one-way output mode, combine the two sets of scissors rods 12 and pull down the gathering frame 16, and snap the upper ends of the two sets of scissors rods 12 into the gathering frame 16. At this time, the sealing baffle 13 seals the sampling port 10. Then pull up the sliding filter screen 21, throw the sampling cylinder 1 into the water. The water flow enters the adjustment chamber 4 from the adjustment water inlet 9, gradually fills the adjustment chamber 4, and pushes up the depth partition 7. The depth partition 7 gradually moves upward to discharge the gas in the airbag 5, reducing the buoyancy. When the sampling cylinder 1 is gradually filled with water until the depth partition 7 presses against the depth rod 8, under the block of the depth rod 8, water cannot enter the sampling cylinder 1, and the buoyancy remains unchanged. At the same time, the depth rod 8 activates the electric telescopic rod 15, and the electric telescopic rod 15 pulls the gathering frame 16, causing the two sets of scissors rods 12 to fork under the elastic force of the opening spring 14, so that the two sets of sealing baffles 13 slide to both sides of the sampling port 10. At this time, the water body flows into the sampling chamber 3 for water sample collection. During the collection process, the buoyancy block 18 gradually slides upward under the action of buoyancy until the inner sealing plate 19 coincides with the sampling port 10 to seal the sampling port 10 from the inside. At this time, the water body collection is completed. Through the buoyancy of the airbag 5 and the limit of the depth rod 8, the disadvantage of being inconvenient to adjust where the collection port opens is solved, so that water body sampling can be conveniently carried out at the required depth.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the utility model claimed.
