Description

Technical Field

[0001] This invention relates to the field of sampling devices for water pollution in mining areas, and specifically to an intelligent sampling device for mining water pollution exploration. Background Technology

[0002] Hydrogeological conditions of mineral deposits are key factors affecting the technical difficulty and safety of mineral resource mining. They directly or indirectly influence mining scheme design, engineering implementation, and economic benefits through various mechanisms. Hydrogeological conditions refer to the general term for the formation, distribution, and variation patterns of groundwater, and mainly include the following elements: groundwater recharge and discharge, aquifer characteristics, groundwater dynamics, and water quality and quantity. During mining operations, changes in the geographical environment of the mine can affect its hydrology, with the most significant impact being on water quality. When minerals and debris from the mine fall into rivers, they not only affect water flow data such as flow velocity and maximum flow rate, but also endanger water quality and cause pollution. Therefore, real-time water quality monitoring is necessary to ensure that water pollution can be detected promptly and to reduce the spread of water pollution. When sampling water sources in mining areas, sampling is usually done using sampling buckets, combined with attached... Figure 10 For reference, after the sampling bucket is lowered into the water source, the water in area a near the inlet of the sampling bucket flows into the sampling bucket, and finally the sampling bucket is taken out. However, existing sampling containers have some drawbacks, such as: The sampling range of the sampling bucket is limited, and the sampling depth in the water source is relatively uniform, resulting in limited sample diversity, incomplete detection data, and a greater risk of detection errors. Furthermore, the polluted water contains some mineral pollutants and sediments, but the existing sampling buckets are not convenient for collecting sediment samples and cannot measure the changes in the content of pollutants and sediments at different depths.

[0003] Therefore, the present invention provides an intelligent sampling device for mining water pollution exploration to solve the above problems. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides an intelligent sampling device for mining water pollution exploration, which solves the problem that the existing sampling buckets have a limited sampling range when sampling polluted water and polluted sediment, resulting in incomplete detection data.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: An intelligent sampling device for mining water pollution exploration includes a loading shell and a hemispherical shell; Wastewater sample collection bottles are arranged in a circular array within the loading shell, with N rings where N is an integer and N≥2. One of the wastewater sample collection bottles in each ring is located on the diameter line of the loading shell. A water pump is slidably installed at the bottom of the loading shell along the diameter line, and the outlet of the water pump is connected to the lower port of each wastewater sample collection bottle on the diameter line of the loading shell. The lower end of the loading shell is fixedly connected to an outer ring, and N-1 lifting rings are inserted and moved up and down inside the outer ring. The lifting rings are nested inside each other, and the outer ring and the outermost lifting ring, as well as the two adjacent lifting rings, are fixed by a stopper. The hemispherical shell is fixedly connected to the innermost lifting ring. The side of the hemispherical shell has a circular array of slots, and an arc-shaped rotating plate rotates through the slots via a rotating shaft. A bird beak tube passes through the arc-shaped rotating plate, and a push plate assembly is installed on the bird beak tube. When the bird beak tube extends out of the hemispherical shell, the push plate assembly pushes open the blocker. A sediment filter is fixedly connected to the bottom of the loading shell in a circular array. The sediment filter has N filter chambers, and the upper end of the filter chamber is provided with an inlet and an outlet. A power source is fixedly connected to the upper center of the loading shell. The output shaft of the power source has a first push rod that rotates, an attached lifting ring that is fixedly connected, and a second push rod that rotates. The other end of the first push rod rotates on the water pump, and the other end of the second push rod rotates inside the arc-shaped rotating plate. A first hose is fixed between the attached lifting ring and the water inlet of the water pump, and a second hose is fixed between the attached lifting ring and the beak pipe. The attached lifting ring moves up and down around the mud and sand filter. The first hose and the second hose are aligned with the water outlet and water inlet of the filter chamber, respectively. Through the above technical solution, firstly, the power source drives the water pump to move laterally via the first push rod, allowing the water pump to connect to the sewage sample collection bottles one by one, thus collecting sewage samples from different depths into different sewage sample collection bottles for separate testing later. Secondly, the power source pushes the arc-shaped rotating plate via the second push rod, which moves the beak tube out of the hemispherical shell, enabling sampling of sewage from different areas at the same depth, resulting in a wider sampling range. Thirdly, when the push plate assembly pushes open the stopper, multiple lifting rings move downwards one by one, causing the hemispherical shell to gradually move downwards, enabling sampling of sewage from different depths, resulting in a wider sampling range, and further enhancing the sampling efficiency as the hemispherical shell moves downwards. The arc-shaped rotating plate can be rotated back into the hemispherical shell, and the bird's beak tube can be returned to the hemispherical shell, realizing the reset function of the arc-shaped rotating plate and the bird's beak tube. Fourth, when the power source drives the attached lifting ring to move down, the first hose and the second hose can be aligned with the outlet and inlet of the filter chamber at different heights, which can separate the silt and sand at different depths for sampling. The filter separates the sewage and silt, which can reduce the wear on the water pump and extend the service life of the water pump. Secondly, it can separate the sewage and silt for sampling and subsequent testing. Fifth, when the output shaft of the power source moves up, the second push rod and the arc-shaped rotating plate can be used to drive the hemispherical shell and the lifting ring to move up and back to their original positions. The first push rod can also be used to drive the water pump back to its original position.

[0006] Preferably, the wastewater sample collection bottle has 3 rings, with 6 wastewater sample collection bottles in each ring. One of the wastewater sample collection bottles in each ring is located on the diameter line of the loading shell. There are 6 water pumps, such that each water pump slides between three wastewater sample collection bottles respectively. The lifting ring has two rings, an inner ring and a middle ring. The hemispherical shell is fixed inside the inner ring. The inner ring moves up and down through the middle ring, and the middle ring moves up and down through the outer ring. Limiting grooves are provided on the inner side of the middle ring and the inner side of the outer ring. Limiting blocks are integrally formed on the outer side of the inner ring and the outer side of the middle ring. The limiting blocks on the inner ring slide up and down on the limiting grooves of the middle ring, and the limiting blocks on the middle ring slide up and down in the limiting grooves of the outer ring. Blockers are installed between the inner ring and the middle ring, and between the middle ring and the outer ring. Through the above technical solution, the inner ring and the middle ring, and the middle ring and the outer ring are restricted by the sliding of the limiting block in the limiting groove. Firstly, it can prevent the inner ring and the middle ring from rotating and can only move up and down. Secondly, the limiting groove restricts the downward movement of the limiting block, which can prevent the inner ring and the middle ring from moving down too much and coming off downward.

[0007] Preferably, the stopper includes a stop pin, a first spring, and a stopper housing. The stop pin is movably inserted inside the stopper housing. The first spring is fixed between the bottom side of the stopper housing and the stop pin. The stopper housing is inserted inside the lower end of the middle ring, and the stop pin is supported at the lower end of the inner ring. The stopper housing is inserted inside the lower end of the outer ring, and the stop pin is supported at the lower end of the middle ring. The push plate assembly includes a first push plate and a second push plate, both of which are fixedly connected to the outside of the bird beak tube. The distance between the first push plate and the second push plate is greater than the distance between the two stoppers. The length of the first push plate is less than the length of the second push plate. When the bird beak tube moves out of the hemispherical shell, the first push plate pushes the blocking pin of the stopper in the outer ring. When the bird beak tube moves out of the hemispherical shell, the second push plate pushes the blocking pin of the stopper in the middle ring. Through the above technical solution, the first spring pushes the blocking pin, the blocking pin of the outer ring blocks the middle ring upward, and the blocking pin of the middle ring blocks the inner ring upward, so that the outer ring, middle ring and inner ring support each other. The first push plate first pushes open the blocking pin of the outer ring, so that the middle ring, inner ring and hemispherical shell move down together. The second push plate then pushes open the blocking pin of the middle ring, so that the inner ring and hemispherical shell move down together again. By precisely controlling the falling sequence, the hemispherical shell can be moved down twice in sequence.

[0008] Preferably, a slide is fixedly connected to the lower side of the loading shell. The slide is a T-shaped groove slide. A third sealing plate slides laterally inside the slide. The water pump is fixedly connected to the lower side of the third sealing plate. The water outlet of the water pump passes upward through the third sealing plate. The end of the first push rod rotates inside the end of the third sealing plate. A frustum-shaped opening is provided on the lower side of the loading shell, and an inner tube is integrally formed on the bottom side of the inner side of the loading shell. The inner tube is aligned with the frustum-shaped opening and is inserted upward into the lower end of the sewage sample collection bottle. The third sealing plate slides below the frustum-shaped opening. The length and width of the third sealing plate are greater than the diameter of the frustum-shaped opening, so that when the third sealing plate moves below the frustum-shaped opening, it blocks the lower end of the frustum-shaped opening. The diameter of the water pump's outlet is smaller than the diameter of the frustum-shaped opening. Through the above technical solution, the third sealing plate can block the frustum-shaped opening, so that the water jet from the pump has enough water pressure to rush into the sewage sample collection bottle, and when the third sealing plate moves a certain distance laterally, it can still ensure that the water outlet of the pump is connected to the frustum-shaped opening.

[0009] Preferably, an inner tube is provided at the lower end of the wastewater sample collection bottle, and the bottom inner tube passes upward through the inner tube of the collection bottle. A one-way valve is installed inside the bottom inner tube. The inlet of the one-way valve faces the frustum-shaped opening and the outlet faces the inside of the wastewater sample collection bottle. A pipe opening sealing plate is rotated through a rotating shaft at the upper end of the inner tube of the collection bottle. The diameter of the pipe opening sealing plate is larger than the diameter of the inner tube of the collection bottle. A torsion spring is fixedly connected between the pipe opening sealing plate and the inner tube of the collection bottle. The torsion spring pushes the pipe opening sealing plate downward. With the above technical solution, when the sewage sample flows from the inner tube at the bottom of the shell into the sewage sample collection bottle, the one-way valve will not obstruct the flow of the sewage sample. When the third sealing plate leaves the frustum-shaped opening, the one-way valve can prevent the sewage sample in the inner tube of the collection bottle from flowing downward from the inner tube at the bottom of the shell, thus achieving the purpose of controlling the one-way flow of the sewage sample. When the sewage sample collection bottle is removed from the loading shell, the torsion spring pushes the sealing plate at the pipe opening downward, blocking the inner tube of the collection bottle, thus preventing the sewage sample from flowing downward from the inner tube of the collection bottle.

[0010] Preferably, the sediment filter has three filter chambers arranged in a linear array. Each filter chamber has a filter switch door installed at its lower end via a hinge. Each filter chamber has a filter screen plate fixedly connected to its upper end. The filter screen plate is inclined. Each filter chamber has a first conical end and a second conical end on its upper side. The height of the first conical end is higher than the height of the second conical end. The filter screen plate is located between the first conical end and the second conical end. The attached lifting ring is fixedly connected with a first sealing plate and a second sealing plate. The water outlet of the second hose passes through the first sealing plate, and the water inlet of the first hose passes through the second sealing plate. The length and width of the first sealing plate are greater than the internal length and width of the first conical end, so that the first sealing plate blocks the first conical end. The length and width of the second sealing plate are greater than the internal length and width of the second conical end, so that the second sealing plate blocks the second conical end. Through the above technical solution, the sewage sample flows through the second hose, the first conical end, the filter chamber of the sediment filter, the second conical end, and the first hose. During this process, the filter screen can filter out the sediment sample in the sewage separately, achieving the purpose of separating the sewage sample and the sediment sample. The length and width of the first sealing plate are larger than the internal length and width of the first conical end, and the length and width of the second sealing plate are larger than the internal length and width of the second conical end. When the first sealing plate and the second sealing plate move up and down a certain distance, they can still block the first conical end and the second conical end, ensuring good sealing performance and stable water pressure. This ensures that when the first sealing plate and the second sealing plate move up and down, the first hose can still be aligned with the second conical end, and the second hose can still be aligned with the first conical end, ensuring the normal flow of sewage.

[0011] Preferably, a polyvinyl chloride plastic sheet is fixedly connected between the periphery of the arc-shaped rotating plate and the periphery of the slotted hemispherical shell, and a corrugated sealing tube is fixedly connected between the upper end of the hemispherical shell and the lower side of the loading shell, wherein the corrugated sealing tube is located inside the innermost lifting ring. Through the above technical solution, the groove of the polyvinyl chloride plastic sheet hemispherical shell is sealed, and the corrugated sealing pipe seals the space between the hemispherical shell and the loading shell. This ensures that the hemispherical shell is sealed after the device is submerged in water, preventing a large amount of sewage carrying mud and sand from entering between the hemispherical shell and the loading shell, thus protecting the internal parts.

[0012] Preferably, there are metal sand loading boxes arranged in a circular array inside the hemispherical shell, the metal sand loading boxes are filled with metal sand, and the slots in the hemispherical shell are located between two adjacent metal sand loading boxes. Through the above technical solution, the metal sand and the metal sand loading box are used to increase the overall weight of the hemispherical shell, ensuring that the hemispherical shell can overcome the buoyancy of the sewage and sink into the depths of the sewage.

[0013] The beneficial effects of this invention are as follows: 1. The power source drives the water pump to move laterally through the first push rod, and controls the water pump to connect to the sewage sample collection bottles of different rings one by one, so as to put sewage samples of different depths into different sewage sample collection bottles, avoid the mixing of sewage of different depths, and separate storage makes it easier to conduct separate testing later. 2. The power source pushes the arc-shaped rotating plate through the second push rod. The arc-shaped rotating plate drives the bird beak tube to move out of the hemispherical shell, which can sample sewage from different areas at the same depth. The bird beak tube rotates while sucking up sewage samples, which can suck up sewage from a larger area. The sampling range is wider, rather than just sucking up sewage from a narrow area. The sewage pollution data is closer to the pollution data of the entire water source, reducing errors and making the data more reliable after testing. 3. When the push plate assembly pushes open the blocker, multiple lifting rings can move downwards one by one, thereby causing the hemispherical shell to gradually move down, which can sample sewage at different depths and has a wider sampling range. 4. Furthermore, when the hemispherical shell moves downward, the arc-shaped rotating plate can rotate back into the hemispherical shell, and the bird beak tube can return to the hemispherical shell, realizing the reset function of the arc-shaped rotating plate and the bird beak tube. Automatic reset makes the automation level higher, requiring no other additional operations, and making it more convenient to use. 5. When the power source drives the attached lifting ring to move down, the first hose and the second hose can be aligned with the outlet and inlet of the filter chamber at different heights, which can separate the silt and sand at different depths. The filter separates the sewage and silt, which can reduce the wear on the water pump and extend the service life of the water pump. It can also separate the sewage and silt for sampling and subsequent testing. 6. When the output shaft of the power source moves upward, the second push rod and the arc-shaped rotating plate can be used to drive the hemispherical shell and the lifting ring to move back to their original positions. Alternatively, the first push rod can be used to drive the water pump back to its original position.

[0014] In summary, this device can sample wastewater from different areas at different depths, providing a wider sampling range and more comprehensive testing. This results in subsequent testing data that is closer to the average level of water pollution, ensuring the reliability of the data and reducing errors. Furthermore, it can sample sludge from different areas at different depths, detecting changes in sludge content at various depths, providing more comprehensive data. The separate sampling of wastewater and sludge also facilitates separate testing later on. Attached Figure Description

[0026] The following will refer to the attached reference. Figures 1 to 10 The various embodiments of the present invention will be described in detail below. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0027] As attached Figure 1 - Appendix Figure 10 As shown, an intelligent sampling device for mining water pollution exploration includes a loading shell 5, a lifting ring, and a hemispherical shell 7. See appendix Figure 1 The loading shell 5 is cylindrical. A main support frame 2, a storage battery 3, and a wireless remote controller 9 are fixedly connected to the center of the upper side of the loading shell 5. A power source 1 is fixedly connected to the main support frame 2. The power source 1 is one of an electric push rod, an electric cylinder, or a slide table. The power source 1 is placed vertically. The loading shell 5 is annular, so that the output shaft of the power source 1 moves downward through the center of the loading shell 5. The output end of the storage battery 3 is electrically connected to the wireless remote controller 9, and the output end of the wireless remote controller 9 is electrically connected to the power source 1. The wireless remote controller 9 can receive external wireless signals to control the circuit.

[0028] See appendix Figure 1 Appendix Figure 2 Appendix Figure 5 and attached Figure 7The upper end of the loading shell 5 contains a circular array of sample water bottle loading cavities. There are N rings of these cavities, where N is an integer and N≥2. For details on the arrangement of the sample water bottle loading cavities, please refer to the appendix. Figure 2 In this embodiment, the sample bottle loading cavity has 3 rings, with 6 bottles in each ring. One of the 3 rings is arranged along the diameter line of the loading shell 5. This can also be represented as: there are 6 rows arranged in a circular array around the center of the loading shell 5, with 3 bottles in each row. A frustum-shaped opening 40 is provided in the side wall between the lower side of the loading shell 5 and the lower side of the sample bottle loading cavity. The diameter of the frustum-shaped opening 40 increases from top to bottom, so that the vertical cross section of the frustum-shaped opening 40 is frustum-shaped. A shell bottom inner tube 39 is integrally formed on the bottom side of the sample bottle loading cavity. The lower end of the shell bottom inner tube 39 is aligned with the upper end of the frustum-shaped opening 40. See appendix Figure 1 Appendix Figure 5 and attached Figure 7 Each sample bottle contains a wastewater sample collection bottle 4 that moves vertically within its loading chamber. The upper end of each wastewater sample collection bottle 4 has an outlet with a threaded cap for sealing. Unscrewing the cap allows the wastewater sample to be poured out. The lower end of each wastewater sample collection bottle 4 has an inner tube 36. A bottom inner tube 39 passes upwards through the inner tube 36, inserting into the lower end of the wastewater sample collection bottle 4. A one-way valve 38 is installed inside the bottom inner tube 39. The inlet of the one-way valve 38 faces the frustum-shaped opening 40, and the outlet faces the inside of the wastewater sample collection bottle 4. This ensures that wastewater can only enter the wastewater sample collection bottle 4 through the bottom inner tube 39 and cannot flow back into the bottom inner tube 39. (See attached appendix for further details.) Figure 9 A pipe-mouth sealing plate 37 is rotatably mounted on the upper end of the inner tube 36 of the collection bottle via a rotating shaft. The diameter of the pipe-mouth sealing plate 37 is larger than the diameter of the inner tube 36 of the collection bottle. A torsion spring is fixedly connected between the pipe-mouth sealing plate 37 and the inner tube 36 of the collection bottle. One end of the torsion spring is inserted into the pipe-mouth sealing plate 37 and the other end is inserted into the rotating shaft of the inner tube 36 of the collection bottle, so that the torsion spring pushes the pipe-mouth sealing plate 37 downward. When the bottom inner tube 39 is inserted into the sewage sample collection bottle 4, the pipe-mouth sealing plate 37 is pushed open by the bottom inner tube 39. When the sewage sample collection bottle 4 is pulled upward from the sample water bottle loading cavity, the torsion spring pushes the pipe-mouth sealing plate 37 downward until the pipe-mouth sealing plate 37 rotates to a horizontal state and covers the upper end of the inner tube 36 of the collection bottle, preventing the sample water in the sewage sample collection bottle 4 from flowing out of the inner tube 36 of the collection bottle.

[0029] See appendix Figure 5 and attached Figure 7A slide 42 is fixedly connected to the lower side of the loading shell 5. There are six slides 42, each located directly below the six rows of sample water bottle loading chambers, so that each slide 42 is located on the diameter line of the loading shell 5. The slide 42 is a T-shaped groove slide. A third sealing plate 41 slides laterally inside the slide 42. The third sealing plate 41 slides below the frustum-shaped opening 40. The length and width of the third sealing plate 41 are larger than the diameter of the frustum-shaped opening 40, so that when the third sealing plate 41 moves below the frustum-shaped opening 40, it blocks the lower end of the frustum-shaped opening 40. The lower side of the third sealing plate 41 is fixedly connected to... A water pump 12 is connected to the output of a wireless remote control 9. The outlet of the water pump 12 passes upward through the third sealing plate 41. The diameter of the outlet of the water pump 12 is smaller than the diameter of the lower end of the frustum-shaped opening 40. The water pump 12 can still be aligned with the frustum-shaped opening 40 when it moves within a certain range. The output shaft of the power source 1 rotates a first push rod 10 via a rotating shaft. The other end of the first push rod 10 rotates inside the end of the third sealing plate 41, causing the third sealing plate 41 and the water pump 12 to move along the diameter line of the loading shell 5, passing under the three frustum-shaped openings 40 in sequence. Figure 5 Based on the appendix Figure 8 A support base 29 is fixedly connected to the bottom of the loading shell 5 in a circular array. A slider 46 is integrally formed at the lower end of the support base 29. A groove 45 is provided on the side of the first push rod 10. The slider 46 slides in the groove 45. The support base 29 and the slider 46 limit the movement trajectory of the first push rod 10. When the lower end of the first push rod 10 moves up and down, its upper end moves laterally.

[0030] See appendix Figure 3 Appendix Figure 5 Appendix Figure 6 and attached Figure 7 The lower end of the loading shell 5 is fixedly connected to an outer ring 15. A floating ring 6 is fixedly fitted between the loading shell 5 and the outer side of the outer ring 15. The floating ring 6 is filled with air, allowing the device to float on the water surface. N-1 lifting rings are vertically inserted inside the outer ring 15, with the lifting rings nested inside each other. In this embodiment, there are two lifting rings: an inner ring 13 and a middle ring 14. The inner ring 13 is vertically inserted inside the middle ring 14, and the middle ring 14 is vertically inserted inside the outer ring 15. Limiting grooves 43 are provided on the inner side of ring 14 and the inner side of outer ring 15. Limiting blocks 44 are integrally formed on the outer side of inner ring 13 and the outer side of middle ring 14. The limiting blocks 44 on inner ring 13 slide up and down on the limiting grooves 43 of middle ring 14, and the limiting blocks 44 on middle ring 14 slide up and down in the limiting grooves 43 of outer ring 15. Blockers 35 are installed between inner ring 13 and middle ring 14 and between middle ring 14 and outer ring 15 and are fixed by the blockers 35.

[0031] See appendix Figure 3 Appendix Figure 5 Appendix Figure 6and attached Figure 7 A hemispherical shell 7 is fixed inside the inner ring 13. The hemispherical shell 7 is hemispherical in shape. A flushing opening is provided at the lower end of the hemispherical shell 7, and a bottom sealing cap 31 is threaded into the flushing opening. Metal sand loading boxes 17 are arranged in a circular array inside the hemispherical shell 7. The metal sand loading boxes 17 are filled with metal sand. The hemispherical shell 7 has slots arranged in a circular array on its side. The slots of the hemispherical shell 7 are located between two adjacent metal sand loading boxes 17. An arc-shaped rotating plate 19 rotates within the slot via a rotating shaft. The output shaft of the power source 1 rotates to provide a second push rod 30. The other end of the rod 30 rotates inside the arc-shaped rotating plate 19. To prevent a large amount of sewage from entering the hemispherical shell 7, a polyvinyl chloride plastic sheet 8 is fixedly connected between the periphery of the arc-shaped rotating plate 19 and the periphery of the slotted hemispherical shell 7. A corrugated sealing pipe 16 is fixedly connected between the upper end of the hemispherical shell 7 and the lower side of the loading shell 5. The corrugated sealing pipe 16 is located inside the inner ring 13. A bird beak pipe 28 passes through the arc-shaped rotating plate 19. A push plate assembly is installed on the bird beak pipe 28. When the bird beak pipe 28 extends out of the hemispherical shell 7, the push plate assembly pushes open the blocker 35.

[0032] See appendix Figure 3 Appendix Figure 4 and attached Figure 5 A sediment filter 20 is fixedly connected to the bottom of the loading shell 5 in a circular array. The sediment filter 20 is detachably fixed by being threaded into the bottom of the loading shell 5 at its upper end. The sediment filter 20 has N filter chambers. The upper end of each filter chamber is provided with an inlet and an outlet. The sediment filter 20 has 3 filter chambers arranged in a linear array. The lower end of each filter chamber is equipped with a filter switch door 21 that is rotatably installed via a hinge. The upper end of each filter chamber is fixedly connected with a filter screen plate 24. The filter screen plate 24 is inclined. The upper side of each filter chamber is provided with a first conical end 25 and a second conical end 27. The height of the first conical end 25 is higher than the height of the second conical end 27. The filter screen plate 24 is located between the first conical end 25 and the second conical end 27. See appendix Figure 3 and attached Figure 4A first hose 11 is fixed to the inlet end of the water pump 12, and a second hose 18 is fixed to the end of the beak pipe 28. An attached lifting ring 22 is fixedly connected to the output shaft of the power source 1. A first sealing plate 23 and a second sealing plate 26 are fixedly connected inside the attached lifting ring 22. The outlet end of the second hose 18 passes through the first sealing plate 23, and the inlet end of the first hose 11 passes through the second sealing plate 26. The length and width of the first sealing plate 23 are greater than the internal length and width of the first conical end 25, so that the first sealing plate 23 blocks the first conical end 25. The length and width of the second sealing plate 26 are greater than the internal length and width of the second conical end 27, so that the second sealing plate 26 blocks the second conical end 27. The first hose 11 is aligned with the second conical end 27, and the second hose 18 is aligned with the first conical end 25.

[0033] As attached Figure 7 As shown, the one-way valve 38 includes a sealing ball 3801, a second spring 3802, and a valve body 3803. The valve body 3803 is fixed inside the inner tube 39 at the bottom of the shell. The inner diameter of the upper end of the valve body 3803 is larger than the inner diameter of the lower end. The sealing ball 3801 is inserted and moved up and down inside the upper end of the valve body 3803. The diameter of the sealing ball 3801 is larger than the inner diameter of the lower end of the valve body 3803. The second spring 3802 is fixedly connected between the sealing ball 3801 and the lower end of the valve body 3803. The working principle of the one-way valve 38 is as follows: the one-way valve 38 is a common one-way valve in the prior art, and the fluid flows from the lower end of the valve body 3803 to the upper end.

[0034] As attached Figure 5 and attached Figure 6 As shown, the blocker 35 includes a blocking pin 3501, a first spring 3502, and a blocker housing 3503. The blocking pin 3501 is movably inserted into the blocker housing 3503. The first spring 3502 is fixed between the bottom side of the blocker housing 3503 and the blocking pin 3501. The blocker 3503 is located within the blocker 35 between the inner ring 13 and the middle ring 14. The blocker housing 3503 is inserted into the lower inner side of the middle ring 14. The blocking pin 3501 is supported at the lower end of the inner ring 13. Inside the stopper 35 between the middle ring 14 and the outer ring 15, the stopper housing 3503 is inserted into the lower inner side of the outer ring 15, and the stopper pin 3501 is supported at the lower end of the middle ring 14. A ring bottom slope 34 is provided on the lower outer edge of the inner ring 13 and the middle ring 14. When the stopper pin 3501 leaves the lower part of the inner ring 13 or the middle ring 14, the ring bottom slope 34 can make the stopper pin 3501 leave the lower part of the inner ring 13 or the middle ring 14 more smoothly, and the triggering process is smoother. The push plate assembly includes a first push plate 32 and a second push plate 33. Both the first push plate 32 and the second push plate 33 are fixedly connected to the outside of the bird beak tube 28. The distance between the first push plate 32 and the second push plate 33 is greater than the distance between the two stoppers 35. The length of the first push plate 32 is less than the length of the second push plate 33. When the bird beak tube 28 moves out of the hemispherical shell 7, the first push plate 32 pushes the blocking pin 3501 of the stopper 35 in the outer ring 15. When the bird beak tube 28 moves out of the hemispherical shell 7, the second push plate 33 pushes the blocking pin 3501 of the stopper 35 in the middle ring 14.

[0035] The working principle of this device is as follows: The sampling personnel used an external wireless signal transmitting device to control the wireless remote control 9, which in turn controlled the operation of the power source 1 and the water pump 12. When the wireless remote control 9 powers on the water pump 12, the water flows sequentially through the beak pipe 28, the second flexible hose 18, the first conical end 25, the filter chamber of the sediment filter 20, the second conical end 27, the first flexible hose 11, the water pump 12, the frustum-shaped opening 40, and the one-way valve 38 before flowing into the wastewater sample collection bottle 4. During this process, the filter screen 24 filters out sediment particles from the sample water. (Refer to the appendix for more details.) Figure 10 At this point, the initial sampling range is the uppermost region b; While the above operations are being performed, the wireless remote controller 9 controls the power source 1 to power on. The output shaft of the power source 1 moves downward. Firstly, the output shaft of the power source 1 drives the lower end of the first push rod 10 to move downward, and the upper end of the first push rod 10 moves towards the center of the loading shell 5. The first push rod 10 drives the third sealing plate 41 to slide, but at this time the third sealing plate 41 has not left the frustum-shaped opening 40. The water outlet of the water pump 12 is still located below the frustum-shaped opening 40, so that the sample water continues to flow into the sewage sample collection bottle 4. Secondly, the output shaft of the power source 1 pushes the second push rod 30. The lower ends of the second push rod 30 move away from each other in a circle. The second push rod 30 pushes the arc-shaped rotating... The plate 19 rotates, causing the arc-shaped rotating plate 19 to drive the bird's beak tube 28 to extend out of the hemispherical shell 7. Thirdly, the output shaft of the power source 1 drives the attached lifting ring 22 to move downwards. The attached lifting ring 22 drives the first sealing plate 23 and the second sealing plate 26 to move downwards. However, at this time, the first sealing plate 23 still blocks the first conical end 25, and the second sealing plate 26 still blocks the second conical end 27, so that the second hose 18 is still connected to the first conical end 25, and the first hose 11 is still connected to the second conical end 27. That is to say, during the first, second, and third points mentioned above, the water pump 12 continuously operates and continuously samples water. (Refer to the attached...) Figure 10 At this point, the sampling range is the uppermost region c; Afterwards, the water pump 12 stops working, the output shaft of the power source 1 continues to move downward, and the beak tube 28 moves outward until the first push plate 32 pushes the blocking pin 3501 of the blocker 35 in the outer ring 15, so that the blocking pin 3501 no longer blocks the middle ring 14. The middle ring 14, the inner ring 13 and the hemispherical shell 7 move downward due to gravity. At this time, the distance between the hemispherical shell 7 and the output shaft of the power source 1 becomes farther, and the lower end of the second push rod 30 moves closer to each other, so that the arc-shaped rotating plate 19 drives the beak tube 28 to rotate back into the hemispherical shell 7 in the opposite direction. The output shaft of power source 1 continues to move downwards. Firstly, the output shaft of power source 1 drives the lower end of the first push rod 10 downwards, while the upper end of the first push rod 10 continues to move towards the center of the loading shell 5. The first push rod 10 drives the third sealing plate 41 to slide, at which point the third sealing plate 41 leaves the frustum-shaped opening 40 and reaches below the next frustum-shaped opening 40. Secondly, the output shaft of power source 1 pushes the second push rod 30, and with each revolution, the lower ends of the second push rod 30 move away from each other. The second push rod 30 pushes the arc-shaped rotating plate 19 to rotate, causing the arc-shaped rotating plate 19 to drive the bird beak tube 28 to move, until the arc-shaped rotating plate 19 and the bird beak tube 28 return to their initial state. At three points, the output shaft of the power source 1 drives the attached lifting ring 22 to move continuously downward, and the attached lifting ring 22 drives the first sealing plate 23 and the second sealing plate 26 to move downward. At this time, the first sealing plate 23 leaves the first pointed cone end 25 and moves to the first pointed cone end 25 in the lower filter chamber, and the second sealing plate 26 leaves the second pointed cone end 27 and moves to the second pointed cone end 27 in the lower filter chamber, so that the second hose 18 is connected to the first pointed cone end 25 below, and the first hose 11 is connected to the second pointed cone end 27 below. Then, the next sewage sampling is started according to the above, and the sample water of the middle area b and area c is obtained. After sampling again, the output shaft of power source 1 continues to move downward, and the beak tube 28 moves outward until the second push plate 33 pushes the blocking pin 3501 of the blocker 35 in the middle ring 14, so that the blocking pin 3501 no longer blocks the inner ring 13. The inner ring 13 and the hemispherical shell 7 move downward due to gravity. The next sampling process begins as described above, and the sample water in the following regions b and c is obtained. After three samplings are completed, all sample water from regions b and c is obtained. The output shaft of power source 1 moves upward. The output shaft of power source 1 drives the entire hemispherical shell 7 to move upward through the second push rod 30 and the arc-shaped rotating plate 19. The hemispherical shell 7 drives the inner ring 13 to move upward. The inner ring 13 drives the middle ring 14 to move upward through the limiting block 44 until the hemispherical shell 7, the inner ring 13 and the middle ring 14 have all moved back to their original positions. The stopper 35 then pushes the middle ring 14 and the inner ring 13 again. At the same time, the output shaft of power source 1 drives the attached lifting ring 22 to move back to its original position. The output shaft of power source 1 pushes the third sealing plate 41 and the water pump 12 back through the first push rod 10, completing the reset. Then remove the device from the sewage source, pull out the sewage sample collection bottle 4 upwards, block the inner tube 36 of the collection bottle with the tube sealing plate 37 to prevent the sample water from flowing out, then unscrew the bottom sealing cap 31, put your hand into the hemispherical shell 7 from the bottom end, unscrew the mud and sand filter 20 to take out the mud and sand sample, or rinse the inside of the hemispherical shell 7 after unscrewing the bottom sealing cap 31.
