Description

Technical Field

[0001] The present invention relates to the technical field of biological water sampling equipment, and particularly to a biological early warning sample collection and sampling device for sudden water pollution. Background Art

[0002] Sudden water pollution refers to the situation where a large amount of harmful substances suddenly enter the water body due to accidental accidents or human factors, resulting in a sharp deterioration of water quality. When sudden water pollution occurs, it is necessary to immediately use biological water sampling equipment to carry out sampling and detection work, which is not only to evaluate the current degree of pollution, but also to provide a scientific basis for subsequent emergency response, pollution control, and ecological restoration. Among them, biological water sampling equipment is a tool specifically used for collecting and analyzing biological samples and their related environmental parameters in water bodies, and is widely used in fields such as water quality monitoring, ecological research, and pollution early warning.

[0003] Existing biological water sampling equipment mainly collects water bodies and incidentally collects biological samples in the water bodies during sampling, aiming to understand the species composition and abundance of phytoplankton and zooplankton in the water bodies. Therefore, the number of samples such as algae and plankton obtained by sampling is small. However, when sudden water pollution occurs, people need to establish a more sensitive biological early warning system. At this time, more samples of algae and plankton are required for more detailed analysis or testing, and existing biological water sampling equipment is difficult to meet the sampling requirements in the case of sudden water pollution.

[0004] Based on the above situation, the present invention proposes a biological early warning sample collection and sampling device for sudden water pollution that is convenient for plankton to attach. Summary of the Invention

[0010] In one embodiment, a balancing mechanism is further included. The balancing mechanism is arranged on the mounting plate frame.

Detailed Description of the Invention

[0036] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0037] Embodiment 1

[0038] A biological early warning sample collection and sampling device for sudden water pollution, such as Figures 1-7As shown in the figure, it includes an installation plate frame 1, a sampling tank 11, a flow-stopping ball 1101, a deflector plate frame 12, a fixing frame 13, a limiting plate 14, a collection frame 15 and an opening / closing plate 16. In the middle of the installation plate frame 1, sampling tanks 11 are fixedly connected in a circumferentially equally spaced manner. Inside the sampling tank 11, a flow-stopping ball 1101 is movably connected to the lower side. In the middle of the installation plate frame 1, a fixing frame 13 is fixedly connected. Outside the fixing frame 13, deflector plate frames 12 are fixedly connected in a circumferentially equally spaced manner. At the top of the deflector plate frame 12, a limiting plate 14 is slidably connected. At the bottom of the limiting plate 14, a collection frame 15 is fixedly connected. At the bottom of the deflector plate frame 12, an opening / closing plate 16 is rotatably connected.

[0039] When researchers need to collect samples of water bodies, algae, plankton, etc. in the water bodies, they can use an external hoisting device to lift components such as the installation plate frame 1 and place them into the water bodies. At this time, components such as the installation plate frame 1, the sampling tank 11, and the deflector plate frame 12 will all quickly sink under the action of gravity. During this period, the flow-stopping ball 1101 will move upward relative to the sampling tank 11 under the action of the impact of the water flow and water pressure and no longer block the water inlet at the lower part of the sampling tank 11. Then the water flow will enter the sampling tank 11 through the water inlet, and the air in the sampling tank 11 will be discharged from the water outlet at the upper part. In this way, normal sampling of the water body can be carried out. And the opening / closing plate 16 will also rotate upward and open under the action of the impact of the water flow and water pressure during the sinking process. Then the water flow will enter the deflector plate frame 12 through the water inlet at the lower part of the deflector plate frame 12, and the gas in the deflector plate frame 12 will also be squeezed out by the water flow. When the inside of the deflector plate frame 12 is filled with water, the excess water will be discharged from the water outlet at the upper part of the deflector plate frame 12. During this period, when the water flow passes through the collection frame 15, the collection frame 15 can intercept and capture small algae, plankton, etc. in the water flow and provide more attachment points for them. In this way, more samples of algae, plankton, etc. can be collected and used for more detailed analysis or testing later. When components such as the installation plate frame 1 sink to the bottom of the water, the flow-stopping ball 1101 and the opening / closing plate 16 will both move reversely and reset under the action of their own gravity and re-block the water inlets of the sampling tank 11 and the deflector plate frame 12. After the sampling is completed, researchers can use an external hoisting device to take out components such as the installation plate frame 1 from the water. During this period, the already reset flow-stopping ball 1101 and opening / closing plate 16 can prevent the water body samples inside the sampling tank 11 and the deflector plate frame 12 from being discharged from the lower water inlets. When researchers need to analyze and test with more algae, plankton, etc., they can pull out the collection frame 15 upward through the limiting plate 14 and take the algae, plankton, etc. attached to the collection frame 15.

[0040] Embodiment 2

[0041] On the basis of Embodiment 1, as Figure 8 and Figure 9As shown in the figure, it further includes a collection mechanism. The collection mechanism is arranged on the mounting plate frame 1. The collection mechanism includes a current collecting plate 2, a connecting pipe 21, a fixing block 22, a limiting plate 23 and a bait box 24. The fixing blocks 22 distributed equidistantly in a circle are fixedly connected to the lower part of the mounting plate frame 1. A current collecting plate 2 is fixedly connected between the bottoms of the fixing blocks 22 distributed equidistantly in a circle. A connecting pipe 21 is fixedly connected and communicated between the current collecting plate 2 and the sampling tank 11. A limiting plate 23 is fixedly connected to the lower side inside the current collecting plate 2. A bait box 24 is fixedly connected inside the current collecting plate 2.

[0042] As Figure 9 shown, the limiting plate 23 is integrally frustum-shaped.

[0043] When components such as the current collecting plate 2 sink downward along with the mounting plate frame 1, due to the relatively large cross-sectional area of the current collecting plate 2, the current collecting plate 2 can better guide and collect water flow and make the water flow enter the sampling tank 11 through the connecting pipe 21, so that water body sampling can be completed more quickly. And when components such as the current collecting plate 2 and the mounting plate frame 1 sink to the bottom of the water, the researchers can start the bait box 24. The bait box 24 can emit a weak green light and a sound signal with a specific frequency to attract organisms such as fish and shrimp at the bottom of the water to pass through the limiting plate 23 and enter the current collecting plate 2. The frustum-shaped limiting plate 23 can effectively prevent the trapped fish and shrimp and other organisms from escaping from the current collecting plate 2. When the researchers take out components such as the mounting plate frame 1 from the water through an external hoisting device, the fish and shrimp and other organisms in the current collecting plate 2 are also taken away from the water body immediately. In this way, the fish and shrimp and other organisms in the water body can be collected and sampled, which is convenient for the researchers to directly understand the impact of water body pollution on aquatic organisms through the fish and shrimp and other organisms and realize more accurate biological early warning.

[0044] As Figures 10-13 shown, it further includes a speed reduction mechanism. The speed reduction mechanism is arranged on the mounting plate frame 1. The speed reduction mechanism includes a mounting frame 3, a mechanical spring box 31, an air bag 32, a threaded rod 33, a lead screw sleeve 34, a transmission belt 35, an exhaust pipe 36, a diversion pipe 37 and a stop block 38. The mounting frame 3 is fixedly connected to the upper part of the mounting plate frame 1. A mechanical spring box 31 is fixedly connected to the middle of the mounting frame 3. An air bag 32 is fixedly connected to the upper part of the mounting plate frame 1. A lead screw sleeve 34 is rotatably connected to the left side of the mechanical spring box 31. A transmission belt 35 is sleeved between the lead screw sleeve 34 and the output end of the mechanical spring box 31. And a one-way gear is connected between the mechanical spring box 31 and its output end. A threaded rod 33 is threadedly connected to the middle of the lead screw sleeve 34. An exhaust pipe 36 is fixedly connected to the lower part of the mechanical spring box 31. An exhaust groove is opened in the lower left part of the exhaust pipe 36. A stop block 38 is slidably connected inside the exhaust pipe 36. The stop block 38 is fixedly connected to the threaded rod 33. Five diversion pipes 37 are fixedly connected and communicated between the exhaust pipe 36 and the air bag 32.

[0045] Before components such as the mounting plate frame 1 are placed into the water body by an external hoisting device, researchers can turn the knob on the mechanical spring box 31 and make the spring inside the mechanical spring box 31 be in an energy storage state. After letting go, the output end of the mechanical spring box 31 will drive the lead screw sleeve 34 to slowly rotate forward through the transmission belt 35, and the slow forward rotation of the lead screw sleeve 34 will drive the threaded rod 33 and the stopper 38 to slowly move upward. At this time, researchers can place components such as the mounting plate frame 1 into the water and let them sink. During this period, since the airbag 32 is in an inflated state, the inflated airbag 32 can buffer and decelerate the sinking components such as the mounting plate frame 1 by virtue of its buoyancy in the water, so as to prevent components such as the mounting plate frame 1 from being inserted into the silt due to too fast sinking speed and causing greater disturbance to the organisms in the water body, thus affecting the collection and sampling results. At the same time, the threaded rod 33 and the stopper 38 will move upward under the action of the lead screw sleeve 34 and gradually no longer block the five diversion pipes 37. The gas in the airbag 32 will then be discharged outward through the exhaust grooves of the diversion pipes 37 and the exhaust pipe 36, and the airbag 32 will gradually become deflated. Since the five diversion pipes 37 are gradually connected from bottom to top, the deflation speed of the airbag 32 is from slow to fast. In this way, when buffering and decelerating the sinking of components such as the mounting plate frame 1 through the airbag 32, the gas in the airbag 32 can only be discharged slowly, so as to ensure the deceleration effect. And when components such as the mounting plate frame 1 have sunk to the bottom of the water, the gas in the airbag 32 can be quickly discharged, and the airbag 32 becomes deflated and is not easily toppled by the impact of the underwater undercurrent for components such as the mounting plate frame 1. When the external hoisting device takes components such as the mounting plate frame 1 out of the water, researchers can first make the lead screw sleeve 34 rotate reversely to drive the threaded rod 33 and the stopper 38 to move downward and reset, and then inject gas into the airbag 32 again. Since a one-way gear is connected between the mechanical spring box 31 and its output end, when the lead screw sleeve 34 rotates reversely and drives the output end of the mechanical spring box 31 to rotate reversely through the transmission belt 35, the spring in the mechanical spring box 31 will not be affected.

[0046] As Figure 1 and Figure 14 shown, it further includes a balance mechanism. The balance mechanism is arranged on the mounting plate frame 1. The balance mechanism includes a balance weight 4, a guide vane 41 and a rotating shaft 42. The balance weights 4 evenly distributed circumferentially are fixedly connected to the outside of the mounting plate frame 1. One side of the balance weight 4 away from the mounting plate frame 1 is rotatably connected with the rotating shaft 42, and one end of the rotating shaft 42 away from the balance weight 4 is fixedly connected with the guide vane 41.

[0047] As Figure 14 shown, both the upper and lower sides of the balance weight 4 are conical.

[0048] As Figure 14 shown, the surface of the guide vane 41 is designed to be streamlined.

[0049] When components such as the mounting plate frame 1 gradually sink under the action of gravity, the four balance weights 4 evenly distributed at equal intervals in a circle can not only increase the overall weight of this sampling device, but also make the center of gravity of this sampling device as close to the center as possible, thereby increasing the stability of this device. Moreover, both the upper and lower sides of the balance weight 4 are conical, which can effectively reduce the water flow resistance. During the sinking process, the guide vanes 41 will rotate 90° under the impact of the water flow and become vertical. At this time, the streamline-designed guide vanes 41 can easily break through the longitudinal water flow and reduce the resistance and impact of the water flow on components such as the mounting plate frame 1, so that components such as the mounting plate frame 1 can sink vertically smoothly, so as to avoid tilting of components such as the mounting plate frame 1 during sinking and affecting the sampling of water bodies by components such as the sampling tank 11. When components such as the mounting plate frame 1 sink to the bottom of the water, the guide vanes 41 will rotate 90° under their own gravity and return to the horizontal state. At this time, the horizontal guide vanes 41 can break through the horizontal undercurrents at the bottom of the water body to reduce the impact of the horizontal undercurrents on components such as the mounting plate frame 1.

[0050] As Figure 1 and Figure 15 shown, it further includes an attachment mechanism. The attachment mechanism is arranged on the mounting plate frame 1. The attachment mechanism includes a rotating frame 5, an adsorption film 51 and a rotating rod 52. The rotating rods 52 evenly distributed at equal intervals in a circle are all rotatably connected to the lower part of the mounting plate frame 1. A rotating frame 5 is fixedly connected to the outside of the rotating rod 52. An adsorption film 51 is fixedly connected between the rotating frames 5 evenly distributed at equal intervals in a circle.

[0051] As Figure 15 shown, the adsorption film 51 is corrugated.

[0052] When components such as the mounting plate frame 1 gradually sink under the action of gravity, components such as the rotating frame 5 and the adsorption film 51 will also sink downward with the mounting plate frame 1. At this time, the rotating frame 5 and the adsorption film 51 will drive the rotating rod 52 to flip upward together under the impact of the water flow and form a frustum of a cone shape. Moreover, the corrugated adsorption film 51 can intercept and capture algae and plankton in the water body during the sinking process. When components such as the mounting plate frame 1 and the rotating frame 5 sink to the bottom of the water, the rotating frame 5 and the adsorption film 51 will drive the rotating rod 52 to flip downward and reset under their own gravity and contact the bottom sludge. At this time, the corrugated adsorption film 51 can provide attachment points for benthic organisms and epiphytic organisms in the water body and sample them, so as to sample the organisms in the water body more comprehensively.

[0053] It should be understood that the above description is only for exemplary purposes and does not mean to limit the present invention. Those skilled in the art will understand that the variant forms of the present invention will be included within the scope of the claims herein.
