Description

Technical Field

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

[0002] Sudden water pollution refers to a situation where a large amount of harmful substances suddenly enter the water body due to accidents or human factors, causing the water quality to deteriorate sharply. When sudden water pollution occurs, biological water sampling equipment must be used immediately to carry out sampling and testing. This is not only to assess 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 specially used to collect and analyze biological samples in water bodies and their related environmental parameters. It is widely used in water quality monitoring, ecological research and pollution early warning.

[0003] Existing biological water sampling equipment mainly collects water and biological samples in the water during sampling, with the aim of understanding the species composition and abundance of phytoplankton and zooplankton in the water. Therefore, the number of samples such as algae and plankton obtained by sampling is relatively small. However, when water pollution occurs suddenly, people need to establish a more sensitive biological early warning system.

DETAILED DESCRIPTION

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

[0037] Example 1

[0038] Biological early warning sample collection and sampling equipment for sudden water pollution, such as Figure 1-Figure 7As shown, it includes a mounting plate frame 1, a sampling tank 11, a stop ball 1101, a guide plate frame 12, a fixing frame 13, a limiting plate 14, a collecting frame 15 and an opening and closing plate 16. The sampling tanks 11 which are evenly spaced are fixedly connected to the middle of the mounting plate frame 1, and the stop ball 1101 is movably connected to the lower side of the inner part of the sampling tank 11. The mounting plate frame 1 is fixedly connected to the middle part, and the guide plate frame 12 which is evenly spaced is fixedly connected to the outside of the fixing frame 13. The top of the guide plate frame 12 is slidably connected to the limiting plate 14, the bottom of the limiting plate 14 is fixedly connected to the collecting frame 15, and the bottom of the guide plate frame 12 is rotatably connected to the opening and closing plate 16.

[0039] When researchers need to collect samples of water bodies and algae and plankton in the water bodies, they can lift the mounting plate frame 1 and other components through external lifting equipment and place them into the water body. At this time, the mounting plate frame 1, the sampling tank 11 and the guide plate frame 12 and other components will all sink rapidly under the action of gravity. During this period, the stop ball 1101 will move upward relative to the sampling tank 11 under the impact of the water flow and the water pressure and will no longer block the water inlet at the bottom of the sampling tank 11. The water flow will then enter the sampling tank 11 through the water inlet and discharge the air in the sampling tank 11 from the upper water outlet, so that the water body can be sampled normally. In addition, the opening and closing plate 16 will also rotate upward and open under the impact of the water flow and the water pressure during the sinking process. The water flow will then enter the guide plate frame 12 through the water inlet at the bottom of the guide plate frame 12, and the gas in the guide plate frame 12 will also be squeezed out by the water flow. When the interior of the guide plate frame 12 is full of water, the excess water will be discharged from the water outlet at the top of the guide plate frame 12. When the water flows through the collecting rack 15, the collecting rack 15 can intercept and capture small algae and plankton in the water flow and provide more attachment points for them, so that more samples of algae and plankton can be collected and used for more detailed analysis or testing later. When the mounting plate rack 1 and other components sink to the bottom of the water, the stopper ball 1101 and the opening and closing plate 16 will move in the opposite direction and reset under the action of their own gravity and re-block the water inlet of the sampling tank 11 and the guide plate rack 12. After the sampling is completed, the researchers can remove the mounting plate rack 1 and other components from the water through external lifting equipment. During this period, the stopper ball 1101 and the opening and closing plate 16 that have been reset can prevent the water samples inside the sampling tank 11 and the guide plate rack 12 from being discharged from the lower water inlet. When the researchers need to use more algae and plankton for analysis and testing, the collecting rack 15 can be pulled out upwards through the limiting plate 14 to take the algae and plankton attached to the collecting rack 15.

[0040] Example 2

[0041] On the basis of Example 1, Figure 8 and Fig. 9As shown, it also includes a collecting mechanism, which is arranged on the mounting plate frame 1. The collecting mechanism includes a collecting plate 2, a connecting pipe 21, a fixing block 22, a limiting plate 23 and an attractant box 24. The fixing blocks 22 equidistantly distributed around the circumference are all fixedly connected to the lower part of the mounting plate frame 1. The collecting plates 2 are fixedly connected between the bottoms of the fixing blocks 22 equidistantly distributed around the circumference. The collecting plates 2 are fixedly connected to and communicated with the sampling tank 11 through a connecting pipe 21. The limiting plate 23 is fixedly connected to the lower side of the current collecting plate 2. The attractant box 24 is fixedly connected to the interior of the current collecting plate 2.

[0042] like Fig. 9 As shown, the limiting plate 23 is in the shape of a truncated cone as a whole.

[0043] When the collecting plate 2 and other components sink with the mounting plate frame 1, due to the large cross-sectional area of ​​the collecting plate 2, the collecting plate 2 can better guide and gather the water flow and allow the water flow to enter the sampling tank 11 through the connecting pipe 21, so that the water sampling can be completed more quickly, and when the collecting plate 2 and the mounting plate frame 1 and other components sink to the bottom of the water, the researchers can start the attractant box 24, which can emit a weaker green light and a sound signal of a specific frequency to attract fish, shrimp and other organisms on the bottom of the water to pass through the limiting plate 23 and enter the collecting plate 2, wherein the truncated cone-shaped limiting plate 23 can effectively prevent the trapped fish, shrimp and other organisms from escaping from the collecting plate 2, and when the researchers remove the mounting plate frame 1 and other components from the water through external lifting equipment, the fish, shrimp and other organisms in the collecting plate 2 are immediately taken away from the water, so that the fish, shrimp and other organisms in the water can be collected and sampled, which is convenient for researchers to directly understand the impact of water pollution on aquatic organisms through fish, shrimp and other organisms and achieve more accurate biological early warning.

[0044] like Figure 10-13 As shown, a deceleration mechanism is also included, which is arranged on the mounting plate frame 1. The deceleration mechanism includes a mounting frame 3, a mechanical clockwork box 31, an airbag 32, a threaded rod 33, a screw sleeve 34, a transmission belt 35, an exhaust pipe 36, a guide pipe 37 and a stopper 38. The mounting frame 3 is fixed to the upper part of the mounting plate frame 1, the middle part of the mounting frame 3 is fixed with the mechanical clockwork box 31, the upper part of the mounting plate frame 1 is fixed with the airbag 32, the left side of the mechanical clockwork box 31 is rotatably connected with the screw sleeve 34, and the screw sleeve A transmission belt 35 is sleeved between 34 and the output end of the mechanical clockwork box 31, and a one-way gear is connected between the mechanical clockwork box 31 and its output end. A threaded rod 33 is threadedly connected to the middle part of the screw sleeve 34. An exhaust pipe 36 is fixedly connected to the lower part of the mechanical clockwork box 31. An exhaust groove is opened at the lower left part of the exhaust pipe 36. A stopper 38 is slidably connected inside the exhaust pipe 36. The stopper 38 is fixedly connected to the threaded rod 33. Five guide pipes 37 are fixedly connected and communicated between the exhaust pipe 36 and the airbag 32.

[0045] Before placing the mounting plate frame 1 and other components into the water body through external lifting equipment, the researchers can turn the knob on the mechanical spring box 31 to put the spring inside the mechanical spring box 31 into an energy storage state. After releasing the knob, the output end of the mechanical spring box 31 will drive the screw sleeve 34 to rotate slowly in the positive direction through the transmission belt 35, and the slow positive rotation of the screw sleeve 34 will drive the threaded rod 33 and the stopper 38 to move slowly upward. At this time, the researchers can place the mounting plate frame 1 and other components into the water and make them sink. During this period, due to the air The airbag 32 is in an expanded state, so the expanded airbag 32 can use its own buoyancy in the water to buffer and slow down the sinking mounting plate frame 1 and other components, so as to prevent the mounting plate frame 1 and other components from being inserted into the silt due to excessively fast sinking speed and causing greater disturbance to the organisms in the water body, thereby affecting the collection and sampling results. At the same time, the threaded rod 33 and the block 38 will move upward under the action of the screw rod sleeve 34 and gradually stop blocking the five guide pipes 37. The gas in the airbag 32 will then be discharged through the guide pipe 37 and the exhaust pipe 36. The air groove is discharged outward, and the air bag 32 gradually becomes deflated. Since the five guide pipes 37 are gradually connected from bottom to top, the deflation speed of the air bag 32 is from slow to fast. In this way, when the sinking of the mounting plate frame 1 and other components is buffered and decelerated by the air bag 32, the gas in the air bag 32 can only be discharged slowly, thereby ensuring the deceleration effect. When the mounting plate frame 1 and other components have sunk to the bottom of the water, the gas in the air bag 32 can be discharged quickly, and the air bag 32 becomes deflated and is not easily impacted by the undercurrent at the bottom of the water. When the external lifting equipment takes the mounting plate frame 1 and other components out of the water, the researchers can first rotate the screw sleeve 34 in the opposite direction and drive the threaded rod 33 and the stop block 38 to move downward and reset, and then re-inject gas into the airbag 32. Since a one-way gear is connected between the mechanical clockwork box 31 and its output end, when the screw sleeve 34 rotates in the opposite direction and drives the output end of the mechanical clockwork box 31 to rotate in the opposite direction through the transmission belt 35, the spring in the mechanical clockwork box 31 will not be affected.

[0046] like Figure 1 and Fig.14 As shown, a balancing mechanism is also included, which is arranged on the mounting plate frame 1. The balancing mechanism includes a balancing block 4, a guide vane 41 and a rotating shaft 42. The balancing blocks 4 that are evenly distributed around the circumference are all fixedly connected to the outside of the mounting plate frame 1. The side of the balancing block 4 away from the mounting plate frame 1 is rotatably connected to the rotating shaft 42, and the end of the rotating shaft 42 away from the balancing block 4 is fixedly connected to the guide vane 41.

[0047] like Fig.14 As shown, the balancing weight 4 is conical on both the upper and lower sides.

[0048] like Fig.14 As shown, the surface of the guide vane 41 is of streamlined design.

[0049] When the mounting plate frame 1 and other components gradually sink under the action of gravity, the four balancing blocks 4 distributed evenly around the circumference can not only increase the overall counterweight of the sampling device, but also make the center of gravity of the sampling device as close to the center as possible, thereby increasing the stability of the device. The upper and lower sides of the balancing block 4 are both conical, which can effectively reduce the water flow resistance. The guide blade 41 will rotate 90° and become vertical under the impact of the water flow during the sinking process. At this time, the streamlined guide blade 41 can easily break the longitudinal water flow. , and reduce the resistance and impact of water flow on the mounting plate frame 1 and other components, so that the mounting plate frame 1 and other components can sink vertically smoothly, so as to avoid the mounting plate frame 1 and other components from tilting during sinking and affecting the sampling of the water body by the sampling tank 11 and other components. When the mounting plate frame 1 and other components sink to the bottom of the water, the guide blade 41 will rotate 90° under the action of its own gravity and return to a horizontal state. At this time, the guide blade 41 in the horizontal state can break the lateral undercurrent at the bottom of the water body to reduce the impact of the lateral undercurrent on the mounting plate frame 1 and other components.

[0050] like Figure 1 and Fig.15 As shown, it also includes an attachment mechanism, which 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 that are evenly distributed around the circumference are all rotatably connected to the lower part of the mounting plate frame 1. The rotating frame 5 is fixedly connected to the outside of the rotating rod 52, and the adsorption film 51 is fixedly connected between the rotating frames 5 that are evenly distributed around the circumference.

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

[0052] When the mounting plate frame 1 and other components gradually sink under the action of gravity, the rotating frame 5, the adsorption membrane 51 and other components will also sink with the mounting plate frame 1. At this time, the rotating frame 5 and the adsorption membrane 51 will drive the rotating rod 52 to flip upward and form an inverted cone shape under the impact of the water flow, and the corrugated adsorption membrane 51 can intercept and capture algae and plankton in the water body during the sinking process. When the mounting plate frame 1 and the rotating frame 5 and other components sink to the bottom of the water, the rotating frame 5 and the adsorption membrane 51 will drive the rotating rod 52 to flip downward and reset under the action of their own gravity and contact the bottom mud. At this time, the corrugated adsorption membrane 51 can provide attachment points for benthic organisms and periphyton in the water body and sample them, so that a more comprehensive collection and sampling of organisms in the water body can be carried out.
