Abstract
Description
Technical Field
[0001] This invention relates to the field of water environment management technology, specifically to a detection and sampling device for water environment pollution management. Background Technology
[0002] In the work of water pollution control, water body testing and sampling are key steps to understand the pollution status and formulate control plans. However, traditional water pollution testing and sampling equipment still has shortcomings. Traditional water pollution detection and sampling equipment usually introduces the water to be sampled directly into the sampling container through a pumping pipe. However, natural water bodies often contain large particulate impurities such as silt, dead branches, and algae. When these impurities enter the sampling container directly with the water flow, they will block the sampling pipe or sampling port, causing sampling to be interrupted. At the same time, the impurities will mix with the water sample and interfere with the subsequent detection process. When traditional equipment is used for sampling, the pumping pipe is directly connected to the external water body, resulting in extremely poor local water flow stability. When the water body is flowing or fluctuating, the water flow speed and direction at the inlet of the pumping pipe will change drastically, causing a large number of air bubbles to be mixed into the pumped water sample, or a large number of impurities deposited at the bottom of the water body to be rolled up and carried into the sampling container due to water flow disturbance. This causes the water sample composition to deviate from the actual situation of the water body and cannot accurately reflect the average pollution state of the water body. Summary of the Invention
[0003] To achieve the above objectives, the present invention provides the following technical solution: a detection and sampling device for water pollution control, comprising: The pre-sampling housing and a support column set on one side of the pre-sampling housing are provided. Guide mechanisms are installed on both sides of the bottom of the pre-sampling housing to guide large particulate impurities in the water to be sampled. A fixed frame is fixedly installed on the outer surface of the pre-sampling housing and a fixed ring is fixedly installed on the outer surface of the support column. A connecting frame is fixedly connected between the fixed frame and the fixed ring to strengthen the connection between the pre-sampling housing and the support column and prevent the equipment from shaking. A base is fixedly installed at the bottom of the support column and casters are installed at the four corners of the bottom of the base to facilitate the overall movement of the equipment and adapt to different sampling locations. A water inlet mechanism is installed at the bottom of the pre-sampling housing and is used to introduce the water to be sampled into the pre-sampling housing. A sampling mechanism is installed in the middle of the pre-sampling shell and is used to sample the water entering the pre-sampling shell. The bottom of the pre-sampling housing cavity is wavy, and the middle of the bottom of the pre-sampling housing cavity is convex arc-shaped. The guide mechanism is located at the concave arc-shaped parts on both sides of the pre-sampling housing cavity. The bottom of the pre-sampling housing cavity is designed so that large particulate impurities in the water to be sampled are guided by the guide mechanism to settle at the concave part of the bottom of the pre-sampling housing cavity cavity, thus avoiding impurities interfering with the sampling.
[0004] Preferably, the water inlet mechanism includes a water storage box, which is fixedly installed in the middle of the bottom of the pre-sampling housing. A connecting pipe is fixedly installed at the bottom of the water storage box, and a water suction pipe is rotatably installed at the bottom end of the connecting pipe. The water suction pipe can be rotated to adjust its angle to adapt to different water intake positions and draw external water into the connecting pipe. A water inlet pipe and a water blocking component are fixedly installed at the bottom of the inner cavity of the water storage box. The water inlet pipe is connected to the connecting pipe and guides the water in the water storage box into the pre-sampling housing. The water blocking component is located directly above the water inlet pipe and is squeezed and fitted to the water inlet pipe. The water blocking component is located directly above the water inlet pipe to control the opening and closing of the water inlet pipe.
[0005] Preferably, there are six connecting pipes, and the six connecting pipes are evenly distributed at the bottom of the water storage box. The connecting pipes connect the water storage box and the water pumping pipe, and guide the water pumped by the water pumping pipe into the water storage box. The distribution of multiple pipes can improve the water intake efficiency.
[0006] Preferably, the water-blocking component includes a water-blocking cone block, and a sealing disc is fixedly installed on the top of the water-blocking cone block. The sealing disc is squeezed and adapted to the top of the water inlet pipe. The water-blocking cone block is inserted into the water inlet pipe to initially block the water flow. At the same time, the cone surface can guide the water flow to impact the sealing disc.
[0007] Preferably, a return spring is fixedly installed at the bottom edge of the sealing disc. There are four return springs, and the four return springs are evenly distributed along the axis of the sealing disc. The sealing disc is tightly attached to the water inlet pipe by the elastic force of the return springs to prevent backflow of water when no sample is taken.
[0008] Preferably, the sampling mechanism includes a sampling housing and a motor. The sampling housing is fixedly installed on the top of the pre-sampling housing, extending through the pre-sampling housing and into its interior. The motor is fixedly installed on the top of the sampling mechanism via a bracket. A water guide pipe is fixedly installed at the middle of the bottom of the sampling housing, guiding water from inside the pre-sampling housing into the sampling housing. A drive shaft is fixedly installed at the output end of the motor, extending through the sampling housing and to its bottom. A spiral water guide vane one and a spiral water guide vane two are fixedly installed sequentially from top to bottom on the outer surface of the drive shaft. The motor drives the drive shaft to rotate, causing the spiral water guide vane one and the spiral water guide vane two to rotate. A sampling element is installed on the outer surface of the sampling housing for collecting water samples. An air extraction pipe is fixedly installed on the top of the sampling housing, which can be connected to an external air extraction device to reduce the air pressure inside the sampling housing and assist the water flow to rise.
[0009] Preferably, a bearing is fixedly installed on the outer surface of the motor, and the bearing is rotatably installed at the axis at the top of the sampling housing. The bearing reduces friction when the transmission shaft rotates, ensuring stable operation.
[0010] Preferably, the first spiral water guide plate is disposed inside the sampling housing and is sealed and adapted to the inner wall of the sampling housing. The second spiral water guide plate is disposed inside the water guide pipe L and is sealed and adapted to the inner wall of the water guide pipe. When the first spiral water guide plate rotates, it guides the water in the pre-sampling housing upward into the sampling housing. The second spiral water guide plate assists in conveying the water upward, thereby improving the water guiding efficiency.
[0011] Preferably, the sampling component includes a sampling tube and a sampling bottle. The sampling tube is fixedly installed on the outer surface of the sampling housing. The sampling tube penetrates the pre-sampling housing and extends to its outer side. The sampling tube guides the water inside the sampling housing to the sampling bottle. A sealing ring is fixedly installed at the other end of the sampling tube. The sampling bottle is detachably installed at the end of the sampling tube. The sampling bottle and the sealing ring are sealed and adapted to each other. The sealing ring enhances the sealing performance during sampling. The outer surface of the sampling bottle is provided with a scale. The scale makes it easy to read the sampling amount intuitively and ensures the sampling accuracy.
[0012] Preferably, the guiding mechanism includes an arc-shaped baffle, which is rotatably mounted at the bottom of the pre-sampling housing cavity via a rotating shaft. The arc-shaped baffle is disposed on both sides of the concave surface of the pre-sampling housing. A buffer spring is fixedly connected between the inner curved surface of the arc-shaped baffle and the pre-sampling housing. A guide groove is provided on the outer curved surface of the arc-shaped baffle. The guide groove directionally guides large particles of impurities to gather at the concave area at the bottom of the pre-sampling housing with the water flow. The buffer spring buffers the impact force of the water flow on the arc-shaped baffle and keeps the baffle stable.
[0013] This invention provides a sampling and detection device for water pollution control. It has the following beneficial effects: I. The sampling and testing equipment for water pollution control utilizes a pre-sampling shell and a guiding mechanism. After the sampled water enters the pre-sampling shell, the wave-like structure at the bottom of its inner cavity guides the water flow to both sides. Large particles of impurities in the water flow settle under gravity. Simultaneously, the guide groove of the arc-shaped baffle further directs the impurities, and the buffer spring buffers the impact of the water flow to maintain the stability of the baffle. Ultimately, the impurities settle in the concave areas on both sides. The bottom shape of the pre-sampling shell changes the direction of the water flow, and together with the guiding mechanism, achieves the physical separation and settling of large particles of impurities, preventing impurities from entering the sampling stage with the water flow, reducing the interference of large particles of impurities on the water sample, and improving the accuracy of subsequent testing. At the same time, the pre-sampling shell reduces air bubbles and impurities entering the sampling bottle, preventing the problem of deviation between the water sample composition and the actual water body due to poor local water flow stability.
[0014] II. The water pollution control detection and sampling equipment, through the water inlet mechanism, draws water from the pumping pipe and enters the water storage box through a series of evenly distributed connecting pipes. The water flow pressure overcomes the elastic force of the return spring, pushing the water-blocking cone and sealing plate upward, opening the water inlet pipe. When the water inlet stops, the return spring returns to its original position, the sealing plate and the water inlet pipe are pressed together to seal, and the water-blocking cone is inserted into the water inlet pipe to block the water flow. Multiple connecting pipes improve the water inlet efficiency, and the water-blocking components can prevent backflow and avoid secondary pollution of the water sample.
[0015] III. The sampling and testing equipment for water pollution control, through the setting of the sampling mechanism, the motor drives the transmission shaft to rotate, the second spiral water guide plate transports water upward in the water guide pipe, the first spiral water guide plate further guides water in the sampling shell, and at the same time the air extraction pipe is connected to external equipment to extract air, reduce the air pressure in the shell to assist the water flow to rise, the water sample flows into the sampling bottle through the sampling tube, and the double spiral water guide plates are respectively sealed and adapted to the inner wall of the sampling shell and the water guide pipe to avoid water leakage and improve the sampling success rate.
[0016] IV. The sampling and testing equipment for water pollution control, through the setting of the sampling element, ensures that when the water sample is discharged from the sampling tube, the sealing ring fits tightly with the sampling bottle to prevent leakage. The operator observes the sampling volume through the scale on the outside of the sampling bottle. After the required amount is reached, the sampling bottle is removed and sealed. The sealing ring prevents the water sample from leaking or mixing with air during the collection process, ensuring the accuracy of the sampling volume and improving the reliability of the data.
[0017] V. The water pollution control detection and sampling equipment is equipped with casters, which propel the equipment to the sampling point. The support column supports the pre-sampling shell, and the connecting frame strengthens the structure to prevent the equipment from shaking during sampling. This allows for flexible movement of the equipment, making it suitable for different sites such as rivers and lakes, and expanding its applicable scope. Attached Figure Description

A buffer spring 42 is fixedly connected between the inner curved surface of the arc-shaped baffle 41 and the pre-sampling housing 1. A guide groove 43 is provided on the outer curved surface of the arc-shaped baffle 41. The guide groove 43 guides large particles of impurities to gather at the concave bottom of the pre-sampling housing 1 with the water flow.

Water inlet mechanism 2 is installed at the bottom of pre-sampling housing 1 and is used to introduce the water to be sampled into pre-sampling housing 1. Sampling mechanism 3 is installed in the middle of pre-sampling housing 1 and is used to sample the water entering the pre-sampling housing 1. The bottom of the pre-sampling housing 1 is wavy, and the middle of the bottom of the pre-sampling housing 1 is convex arc. The guide mechanism 4 is set at the concave arc on both sides of the pre-sampling housing 1. The bottom of the pre-sampling housing 1 is designed so that large particles of impurities in the water to be sampled are guided by the guide mechanism 4 and settle in the concave area at the bottom of the pre-sampling housing 1, thus avoiding impurities from interfering with the sampling.
[0022] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figure 5 and Figure 6 As shown, the water inlet mechanism 2 includes a water storage box 21, which is fixedly installed in the middle of the bottom of the pre-sampling housing 1. A connecting pipe 22 is fixedly installed at the bottom of the water storage box 21, and a water suction pipe 23 is rotatably installed at the bottom end of the connecting pipe 22. The water suction pipe 23 can be rotated to adjust the angle to adapt to different water intake positions and draw external water into the connecting pipe 22. A water inlet pipe 24 and a water blocking component 25 are fixedly installed at the bottom of the inner cavity of the water storage box 21. The water inlet pipe 24 is connected to the connecting pipe 22 and guides the water in the water storage box 21 into the pre-sampling housing 1. The water blocking component 25 is located directly above the water inlet pipe 24 and is squeezed and adapted to the water inlet pipe 24. The water blocking component 25 is located directly above the water inlet pipe 24 to control the opening and closing of the water inlet pipe 24.
[0023] There are six connecting pipes 22, and the six connecting pipes 22 are evenly distributed at the bottom of the water storage box 21. The connecting pipes 22 connect the water storage box 21 to the water pumping pipe 23, and guide the water pumped by the water pumping pipe 23 into the water storage box 21. The multiple pipes can improve the water intake efficiency.
[0024] The water-blocking component 25 includes a water-blocking cone block 251. A sealing disc 252 is fixedly installed on the top of the water-blocking cone block 251. The sealing disc 252 is squeezed and adapted to the top of the water inlet pipe 24. The water-blocking cone block 251 is inserted into the water inlet pipe 24 to initially block the water flow. At the same time, the cone surface can guide the water flow to impact the sealing disc 252.
[0025] A return spring 253 is fixedly installed at the bottom edge of the sealing disc 252. There are four return springs 253, and the four return springs 253 are evenly distributed along the axis of the sealing disc 252. The sealing disc 252 is tightly attached to the water inlet pipe 24 by the elastic force of the return springs 253 to prevent backflow of water when no sample is taken.
[0026] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 7 to 8 As shown, the sampling mechanism 3 includes a sampling housing 31 and a motor 32. The sampling housing 31 is fixedly installed on the top of the pre-sampling housing 1, and extends through the pre-sampling housing 1 into its interior. The motor 32 is fixedly installed on the top of the sampling mechanism 3 via a bracket. A water guide pipe 37 is fixedly installed at the middle of the bottom of the sampling housing 31, guiding water from the pre-sampling housing 1 into the sampling housing 31. A drive shaft 33 is fixedly installed at the output end of the motor 32, and the drive shaft 33 extends through the sampling housing 31. Extending to its bottom, the outer surface of the drive shaft 33 is fixedly mounted with a spiral water guide plate 35 and a spiral water guide plate 36 from top to bottom. The motor 32 drives the drive shaft 33 to rotate, and the drive shaft 33 drives the spiral water guide plate 35 and the spiral water guide plate 36 to rotate. A sampling element 39 is installed on the outer surface of the sampling housing 31. The sampling element 39 is used to collect water samples. An air extraction pipe 38 is fixedly installed on the top of the sampling housing 31. The air extraction pipe 38 can be connected to an external air extraction device to reduce the air pressure inside the sampling housing 31 and assist the water flow to rise.
[0027] A bearing 34 is fixedly mounted on the outer surface of the motor 32. The bearing 34 is rotatably mounted at the shaft center at the top of the sampling housing 31. The bearing 34 reduces the friction when the transmission shaft 33 rotates, ensuring stable operation.
[0028] Spiral water guide plate 35 is installed inside the sampling housing 31 and is sealed and adapted to the inner wall of the sampling housing 31. Spiral water guide plate 36 is installed inside the water guide pipe L37 and is sealed and adapted to the inner wall of the water guide pipe 37. When the spiral water guide plate 35 rotates, it guides the water in the pre-sampling housing 1 upward into the sampling housing 31. The spiral water guide plate 36 assists in conveying the water upward, thereby improving the water guiding efficiency.
[0029] The sampling component 39 includes a sampling tube 391 and a sampling bottle 392. The sampling tube 391 is fixedly installed on the outer surface of the sampling housing 31. The sampling tube 391 penetrates the pre-sampling housing 1 and extends to its outer side. The sampling tube 391 guides the water inside the sampling housing 31 to the sampling bottle 392. A sealing ring 393 is fixedly installed at the other end of the sampling tube 391. The sampling bottle 392 is detachably installed at the end of the sampling tube 391. The sampling bottle 392 is sealed and adapted to the sealing ring 393. The sealing ring 393 enhances the sealing performance during sampling. The outer surface of the sampling bottle 392 is provided with a scale 394. The scale 394 facilitates intuitive reading of the sampling volume and ensures sampling accuracy.
[0030] During use, the operator pushes the device with the casters 10 at the bottom of the base 7 to move it to the water environment area to be sampled. The support column 8 and the connecting frame 6 ensure the overall stability of the device and prevent shaking during movement or sampling. The angle of the water pumping pipe 23 is adjusted so that it is inserted into the water to be sampled. The water pump draws water through the water pumping pipe 23. The water flows through six evenly distributed connecting pipes 22 into the water storage box 21, and then through the water inlet pipe 24 to impact the water blocking component 25. The water pressure overcomes the elastic force of the return spring 253, pushing the sealing plate 252 and the water-blocking cone 251 upward, opening the water inlet pipe 24, and allowing water to flow into the pre-sampling housing 1. If pumping stops, the return spring 253 returns to its original position, the sealing plate 252 and the top of the water inlet pipe 24 are pressed together to seal, and the water-blocking cone 251 is inserted into the water inlet pipe 24 to prevent water backflow. The water flow entering the pre-sampling housing 1 flows along its wavy bottom. Large particles of impurities in the water flow are guided by the guide mechanism 4 under the impact of gravity and water flow. The arc-shaped baffle 41 buffers the impact of water flow through the buffer spring 42. The guide groove 43 on the outer curved surface guides the impurities to the concave arc-shaped areas on both sides, and finally settles in the concave bottom, preventing impurities from entering the subsequent sampling stage. The motor 32 is started, and its output end drives the spiral water guide vane 1 35 and spiral water guide vane 2 36 to rotate through the transmission shaft 33. The spiral water guide vane 2 36 rotates in the water guide tube 37, which transports the water separated from impurities in the pre-sampling shell 1 upward to the sampling shell 31. The spiral water guide vane 1 35 further guides the water upward in the sampling shell 31. At the same time, the external equipment can be connected through the air extraction tube 38 to reduce the air pressure in the sampling shell 31 and assist the water flow to rise. After the water flows into the sampling shell 31, it is discharged through the sampling tube 391 and flows into the detachable sampling bottle 392. The sealing ring 393 ensures that the connection is sealed to prevent water sample leakage. The scale 394 on the outer surface of the sampling bottle 392 can be read intuitively to ensure sampling accuracy. After sampling, turn off motor 32 and water inlet power. Reset spring 253 drives water blocking component 25 to seal water inlet pipe 24 to prevent residual water from flowing back. Remove sampling bottle 392 and seal it for preservation to complete the sampling operation.
