A water environment quality monitoring system

Abstract

The application relates to the technical field of water quality monitoring equipment, in particular to a water environment quality monitoring system which comprises a filter plate, an inner barrel body, an outer barrel body, a cleaning assembly, a sampling assembly, a pressing rod and a pedal. A worker pushes the pressing rod inward, so that the pressing rod is integrated with the cleaning assembly. Then the worker repeatedly steps on the pedal. The pedal drives the cleaning assembly and the sampling assembly to cooperate with each other through power transmission of the pressing rod, so that the inner barrel body can be washed. When the washing is completed, the worker pulls the pressing rod outward, so that the pressing rod is separated from the cleaning assembly. Then the worker repeatedly steps on the pedal again. The sampling assembly is driven by power transmission of the pressing rod to realize sampling. The inner barrel body does not need to be manually washed by the worker for many times, and the sampler does not need to be pulled out of the river by the worker to realize sampling. Therefore, the worker does not need to overcome the combined gravity of the sampler and the water sample, so that the working strength of water sample collection is reduced, and the worker's fatigue in the water sample collection process is reduced.

Description

Technical Field

[0001] This invention relates to the field of water quality monitoring equipment technology, and specifically to a water environment quality monitoring system. Background Technology

[0002] Water quality monitoring is the process of monitoring and measuring the types of pollutants in water bodies, the concentrations of various pollutants, and their changing trends, and evaluating the water quality status. The monitoring scope is very broad, including unpolluted and polluted natural water (rivers, lakes, seas, and groundwater) as well as various industrial wastewater. The main monitoring items can be divided into two categories: one is comprehensive indicators reflecting the water quality status, and the other is some toxic substances. The water environment quality monitoring process includes steps such as water sample collection, on-site monitoring, water sample dispensing, and adding fixatives.

[0003] However, in the existing water environment quality monitoring process, one end of the sampling rope must first be fixed to a bridge, and the other end connected to the sampler. Then, the sampler is placed into the river to be tested to collect water. The sampler is then pulled out by the sampling rope, and the water collected in the sampler is used to rinse the settling container multiple times. During the multiple rinsing of the settling container, the staff needs to bend over and hand wash the inner surface of the settling container. Furthermore, when collecting water samples, the staff needs to pull the sampling rope again to pull the sampler out of the river. In all of the above processes, the staff needs to overcome the combined gravity of the sampler and the water sample to complete the sampling work. Therefore, the rinsing work before water sampling and the sampling process during sampling both make the water sampling work quite arduous, which can easily cause fatigue among the staff.

[0004] In view of this, in order to overcome the above-mentioned technical problems, the present invention designs a water environment quality monitoring system, which improves the above-mentioned technical problems. Summary of the Invention

Detailed Implementation

[0051] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0052] This invention provides a water environment quality monitoring system that improves upon the existing technology, where the rinsing work before water sample collection and the sampling process during sampling both result in a high workload for water sample collection, which can easily cause fatigue among staff.

[0053] The technical solution of the present invention is to improve the above-mentioned technical problems. The general idea is as follows: During the water sample collection process, the staff pushes the pressure rod 7 inward, so that the pressure rod 7 is connected to the cleaning component 4 as a whole. Then the staff repeatedly presses the pedal 8. The pedal 8 drives the cleaning component 4 and the sampling component 5 to cooperate through the power transmission of the pressure rod 7, so as to realize the washing of the inner tank 2.

[0054] After rinsing is completed, the staff pulls the lever 7 outward to disengage it from the cleaning component 4, and then repeatedly presses the pedal 8. The power transmission of the lever 7 drives the sampling component 5 to take a sample.

[0055] There is no need for manual bending over to wash the inner tank 2 multiple times, nor is there a need for manual pulling of the sampling rope to pull the sampler out of the river to collect samples. Furthermore, there is no need for manual overcoming of the combined gravity of the sampler and the water sample, thereby reducing the workload of water sample collection and reducing the fatigue caused to staff during the water sample collection process.

[0056] To better understand the above technical solutions, the following will provide a detailed explanation of the above technical solutions in conjunction with the accompanying drawings and specific implementation methods;

[0057] The present invention provides a water environment quality monitoring system, including a filter plate 1, and further comprising:

[0058] Inner barrel 2, the inner barrel 2 is disposed outside the filter plate 1;

[0059] Outer barrel 3, the outer barrel 3 is disposed outside the inner barrel 2, and the upper surface of the outer barrel 3 is rotatably connected to the inner barrel 2;

[0060] Cleaning component 4 is disposed in the interlayer formed between the outer tub 3 and the inner tub 2, and is used to rinse the inner tub 2.

[0061] Sampling component 5, which is disposed on one side of cleaning component 4, is used to collect water samples;

[0062] The through groove 6 is formed on the outer barrel body 3;

[0063] Pressure rod 7, the pressure rod 7 being transversely penetrating through the through groove 6;

[0064] The pedal 8 is fixedly connected to the pressure rod 7 at one end outside the outer barrel 3.

[0065] By adopting the above technical solution, before collecting water samples, it is necessary to collect the water body to be tested and rinse the inner tank 2. When rinsing the inner tank 2, the staff pushes the pressure rod 7 forward, so that the pressure rod 7 is connected to the cleaning component 4 as one unit.

[0066] At this time, the staff steps on pedal 8, and pedal 8 moves downward, which drives the pressure rod 7 fixedly connected to it to move downward. The downward movement of pressure rod 7 transmits power to cleaning component 4, and cleaning component 4 drives inner barrel 2 to rotate in the forward direction through power transmission.

[0067] Then the staff stopped pressing the pedal 8. The pedal 8 returned to its original position with the help of the elastic element. During the process of the pedal 8 returning to its original position, it drove the pressure rod 7, which was fixedly connected to it, to move upward. The upward movement of the pressure rod 7 transmitted the power to the cleaning component 4, and the cleaning component 4 drove the inner barrel 2 to rotate in the opposite direction.

[0068] At the same time, when the staff step on the pedal 8, they come into contact with the sampling component 5. The pressure rod 7 transmits power to the cleaning component 4 and also to the sampling component 5. At this time, the sampling component 5 generates negative pressure to draw the water sample into the inner tank 2.

[0069] Thus, during the rinsing of the inner tub 2, the staff repeatedly press the pedal 8. The pedal 8, through the power transmission between the pressure rod 7 and the cleaning component 4, drives the inner tub 2 to rotate repeatedly in the forward and reverse directions. At the same time, during the repeated pressing of the pedal 8, the sampling component 5 is triggered. The sampling component 5 sucks the water to be tested into the inner tub 2. In conjunction with the forward and reverse rotation of the inner tub 2, the rinsing of the inner tub 2 is achieved.

[0070] When water sampling is carried out after rinsing, the staff pulls the pressure rod 7 outward to disengage the pressure rod 7 from the cleaning component 4. At this time, the staff continues to press the pedal 8 repeatedly. Since the pressure rod 7 is disengaged from the cleaning component 4, the pressure rod 7 will not transmit power to the inner barrel 2. The inner barrel 2 will not rotate due to the up and down movement of the pressure rod 7. Thus, the inner barrel 2 is in a stationary state.

[0071] However, when the staff repeatedly press the pedal 8, the sampling component 5 will still be powered by the pressure rod 7. At this time, the sampling component 5 will still generate negative pressure to draw the water sample into the inner tank 2 for water sample collection.

[0072] Compared to existing technologies, the rinsing work before water sampling and the sampling process during sampling both result in a higher workload for water sampling, which can easily cause fatigue among staff.

[0073] In the process of water sample collection, the staff pushes the pressure rod 7 inward, so that the pressure rod 7 is connected to the cleaning component 4 as one unit. Then the staff repeatedly presses the pedal 8. The pedal 8 drives the cleaning component 4 and the sampling component 5 to cooperate through the power transmission of the pressure rod 7, so as to achieve the washing of the inner tank 2.

[0074] After rinsing is completed, the staff pulls the lever 7 outward to disengage it from the cleaning component 4, and then repeatedly presses the pedal 8. The power transmission of the lever 7 drives the sampling component 5 to take a sample.

[0075] There is no need for manual bending over to wash the inner tank 2 multiple times, nor is there a need for manual pulling of the sampling rope to pull the sampler out of the river to collect samples. Furthermore, there is no need for manual overcoming of the combined gravity of the sampler and the water sample, thereby reducing the workload of water sample collection and reducing the fatigue caused to staff during the water sample collection process.

[0076] As one embodiment of the present invention, the cleaning component 4 includes:

[0077] Rotating block 41, the upper surface of which is fixedly connected to the lower surface of inner barrel 2;

[0078] The spiral rod 42 is located at the center of the rotating block 41 and forms a spiral transmission connection with the rotating block 41. The lower end of the spiral rod 42 is fixedly connected to the bottom end of the inner surface of the outer barrel 3.

[0079] An annular connecting block 43, the inner surface of which is rotatably connected to the outer surface of the rotating block 41;

[0080] Mounting slots 44, a plurality of mounting slots 44 are evenly formed on the outer surface of the annular connecting block 43;

[0081] Pressure plate 45, which is slidably connected to pressure rod 7 located inside outer barrel 3;

[0082] Telescopic sleeve 46, the upper surface of which is fixedly connected to the lower surface of pressure plate 45, and the lower surface of telescopic sleeve 46 is fixedly connected to the bottom end of the inner surface of outer barrel 3;

[0083] Spring 47 is disposed inside telescopic sleeve 46, and both ends of spring 47 are fixedly connected to both ends of the inner surface of telescopic sleeve 46;

[0084] As one embodiment of the present invention, the sampling component 5 includes:

[0085] Airbag 51, the airbag 51 is located between two No. 1 cylindrical tubes, and the bottom end of the airbag 51 is fixedly connected to the inner surface of the outer barrel 3;

[0086] Air inlet 52, which is provided on airbag 51;

[0087] One-way valve 53, wherein the one-way valve 53 is disposed inside the air inlet 52;

[0088] A perforated plug 54 is disposed inside the air inlet 52;

[0089] Air inlet pipe 55, which is fixedly connected to air inlet 52, and extends upward to the outside of outer barrel 3;

[0090] A waterproof and breathable membrane 56 is disposed inside the air inlet pipe 55;

[0091] The three-way pipe 57 includes a first port in the vertical direction and a second port and a third port in the horizontal direction. The first port is fixedly connected to the air inlet pipe 55 at one end outside the outer barrel 3.

[0092] The No. 1 water inlet pipe 58 is fixedly connected to the No. 2 port of the three-way pipe 57 on the side away from the inner barrel 2.

[0093] The second water inlet pipe 59 is fixedly connected to the No. 3 port of the three-way pipe 57 on the side near the inner barrel 2. The end of the second water inlet pipe 59 away from the three-way pipe 57 is in contact with the filter plate 1.

[0094] An exhaust port 510 is provided on the airbag 51 and located below the air inlet 52;

[0095] Second check valve 511, wherein the second check valve 511 is disposed inside the exhaust port 510;

[0096] By adopting the above technical solution, when rinsing the inner surface of the inner barrel 2, the end of the No. 1 water inlet pipe 58 away from the tee pipe 57 is placed into the river. The staff pushes the pressure rod 7 inward, and the pressure rod 7 moves to one side of the inner barrel 2. When the pressure rod 7 moves to one side of the inner barrel 2, the end of the pressure rod 7 located inside the outer barrel 3 is engaged in the installation groove 44 opened on the annular connecting block 43. At this time, the pressure rod 7 is connected to the cleaning component 4 as one unit.

[0097] At this time, the staff member steps on pedal 8, and pedal 8 moves downward, which drives the pressure rod 7 fixedly connected to it to move downward.

[0098] Since the pressure rod 7 is engaged with the mounting groove 44 on the annular connecting block 43 at this time, the pressure rod 7 exerts downward pressure on the annular connecting block 43 during its downward movement, causing the annular connecting block 43 to move downward.

[0099] The inner surface of the annular connecting block 43 is rotatably connected to the rotating block 41, so the annular connecting block 43 drives the rotating block 41 to move downward during its downward movement.

[0100] Since the rotating block 41 is connected to the screw rod 42 by a central screw drive, the rotating block 41 rotates in the forward direction as it moves downward on the screw rod 42.

[0101] The rotating block 41 rotates in the forward direction, causing the inner barrel 2, which is fixedly connected to the upper surface, to rotate in the forward direction.

[0102] At the same time, as the pressure rod 7 moves downward, it drives the pressure plate 45, which is slidably connected to it, to move downward.

[0103] The pressure plate 45 moves downward and presses against the airbag 51 and spring 47 below it. After the airbag 51 is compressed, the second one-way valve 511 at the exhaust port 510 opens, so that the internal gas is discharged from the exhaust port 510.

[0104] When the staff stops pressing the pedal 8 when it reaches the end point, the pedal 8 is no longer under pressure, so the spring 47 and the airbag 51 are no longer under the pressure and return to their elastic deformation.

[0105] During the process of spring 47 and airbag 51 restoring their elastic deformation, they drive pressure plate 45 to move upward;

[0106] The upward movement of the pressure plate 45 causes the pressure rod 7, which is slidably connected to it, to move upward.

[0107] The upward movement of the pressure rod 7 causes the pedal 8 and the annular connecting block 43 to move upward.

[0108] As the annular connecting block 43 moves upward, it drives the rotating block 41 to move upward.

[0109] Since the rotating block 41 is connected to the screw rod 42 by a central screw drive, the rotating block 41 rotates in the opposite direction as it moves upward on the screw rod 42.

[0110] This causes the rotating block 41 to rotate in the opposite direction, which in turn causes the inner barrel 2, which is fixedly connected to the upper surface, to rotate in the opposite direction.

[0111] At the same time, as the pressure on the airbag 51 decreases during the upward movement of the pressure plate 45, the airbag 51 gradually recovers its elastic deformation. During the process of recovering its elastic deformation, the airbag 51 needs to draw air from the perforated plug 54 at the air inlet 52.

[0112] When airbag 51 inhales, one-way valve 53 opens to allow inhalation.

[0113] During the process of air intake 52 provided on the airbag 51, the air pressure in the air intake pipe 55 at the air intake port decreases.

[0114] The decrease in air pressure inside the air inlet pipe 55 causes a decrease in air pressure inside the No. 1 water inlet pipe 58 and the No. 2 water inlet pipe 59 connected by the T-connector 57 at its upper end. As a result, the water flow in the river to be tested enters the No. 1 water inlet pipe 58 and gradually enters the No. 2 water inlet pipe 59 through the No. 1 water inlet pipe 58.

[0115] Water flows into the inner tub 2 through the second water inlet pipe 59, and with the forward and reverse rotation of the inner tub 2, the inner tub 2 is rinsed.

[0116] After one rinse is completed, drain the water in the inner tub 2 from the drain outlet 13. After the water is drained, close the drain outlet 13 and repeat the above actions to achieve multiple rinses of the inner tub 2.

[0117] After the washing is completed, the staff pulls the pressure rod 7 outward, and the pressure rod 7 disengages from the mounting groove 44 on the annular connecting block 43;

[0118] At this time, the pedal 8 is pressed repeatedly. Since the lever 7 is slidably connected to the pressure plate 45, the lever 7 is still connected to the pressure plate 45 after being pulled outward.

[0119] Thus, after the pressure bar 7 is subjected to pressure, it can still drive the pressure plate 45 to move downward again, and the downward movement of the pressure plate 45 can squeeze the airbag 51 again.

[0120] When the airbag 51 is compressed, the second one-way valve 511 at the exhaust port 510 opens, so that the internal gas is discharged from the exhaust port 510.

[0121] When the staff releases the pedal 8, the spring 47 and the airbag 51 are no longer subjected to the compressive force and return to their elastic deformation.

[0122] During the process of restoring elastic deformation, the airbag 51 needs to draw air from the perforated plug 54 at the air inlet 52;

[0123] When airbag 51 inhales, one-way valve 53 opens to allow inhalation.

[0124] During the process of air intake 52 provided on the airbag 51, the air pressure in the air intake pipe 55 at the air intake port decreases.

[0125] The reduced air pressure inside the air inlet pipe 55 causes a decrease in air pressure inside the No. 1 water inlet pipe 58 and the No. 2 water inlet pipe 59 connected by the T-connector 57 at its upper end. As a result, the water flow in the river to be tested enters the No. 1 water inlet pipe 58, and the water flow gradually enters the No. 2 water inlet pipe 59 through the No. 1 water inlet pipe 58, thus achieving sampling.

[0126] Thus, the staff pushes the pressure rod 7 inward, so that the pressure rod 7 engages with the annular connecting block 43. Then the staff repeatedly presses the pedal 8. The pedal 8, through the power transmission of the pressure rod 7, drives the cleaning component 4 and the sampling component 5 to cooperate with each other, causing the inner barrel 2 to rotate repeatedly in the forward and reverse directions, thereby washing the inner barrel 2.

[0127] After rinsing is completed, the staff pulls the pressure rod 7 outward to disengage the pressure rod 7 from the cleaning component 4. At this time, the staff continues to press the pedal 8 repeatedly. Since the pressure rod 7 is disengaged from the mounting groove 44 on the annular connecting block 43, the pressure rod 7 will not transmit power to the inner tub 2 at this time. The inner tub 2 will not rotate due to the up and down movement of the pressure rod 7. Thus, the inner tub 2 is in a stationary state at this time.

[0128] Then, repeatedly press the pedal 8, and the pedal 8 will drive the lever 7 to move up and down repeatedly.

[0129] As the pressure rod 7 moves up and down repeatedly, it drives the pressure plate 45 to repeatedly squeeze the air bag 51, which generates a large negative pressure at the air inlet 52 of the air bag 51. As a result, the water flows into the inner barrel 2 through the first water inlet pipe 58 and the second water inlet pipe 59 in sequence, thus realizing the collection of water samples.

[0130] There is no need for manual bending over to wash the inner tank 2 multiple times, nor is there a need for manual pulling of the sampling rope to pull the sampler out of the river to achieve sampling. Furthermore, there is no need for manual overcoming of the combined gravity of the sampler and the water sample, thereby reducing the workload of water sampling and reducing the fatigue caused to staff during the water sampling process.

[0131] A waterproof and breathable membrane 56 is provided in the air inlet pipe 55. This ensures that the air in the air inlet pipe 55 is unobstructed when the airbag 51 inhales. It also prevents the negative pressure generated in the air inlet pipe 55 due to the airbag 51 inhaling, which would prevent the water from flowing down into the air inlet pipe 55 when the first water inlet pipe 58 and the second water inlet pipe 59 are filled with water samples, thus preventing the sampling component 5 from working properly.

[0132] Furthermore, the spring 47 is placed inside the telescopic sleeve 46, which is formed by two cylindrical barrels slidingly connected. This ensures that the spring 47 can be compressed normally and restore its elastic deformation, while also reducing the phenomenon of the spring 47 tilting when squeezed.

[0133] In one embodiment of the present invention, both the inner barrel 2 and the outer barrel 3 are configured as telescopic barrel structures.

[0134] By adopting the above technical solution, since water sample collection is usually carried out outdoors, both the inner barrel 2 and the outer barrel 3 are designed as telescopic barrel structures, which makes the inner barrel 2 and the outer barrel 3 easy to store and reduces the storage space.

[0135] In one embodiment of the present invention, the diameter of one end of the pressure rod 7 located inside the outer barrel 3 is smaller than the diameter of the mounting groove 44, and a rubber layer 9 is fixedly connected to one end of the pressure rod 7 located inside the outer barrel 3.

[0136] By adopting the above technical solution, by setting the diameter of the end of the pressure rod 7 inside the outer barrel 3 to be smaller than the diameter of the mounting groove 44, it is ensured that the pressure rod 7 can be smoothly inserted into the mounting groove 44. By setting a rubber layer 9 to be fixedly connected to the end of the pressure rod 7 inside the outer barrel 3, the sum of the diameter of the end of the pressure rod 7 inside the outer barrel 3 and the thickness of the rubber layer 9 is greater than the diameter of the mounting groove 44 by 2-4mm. The elasticity of the rubber layer 9 is used so that when the pressure rod 7 is inserted into the mounting groove 44, the rubber layer 9 is squeezed and generates tension force, thereby ensuring the stable connection between the mounting rod and the annular connecting block 43.

[0137] As one embodiment of the present invention, an inclined plate 10 is provided inside the inner barrel 2. The inclined plate 10 is located below the filter plate 1. A water leakage hole 11 is provided on the inclined plate 10. One side wall of the water leakage hole 11 is in contact with the inner surface of the inner barrel 2.

[0138] By adopting the above technical solution, when water flows out from the No. 2 inlet pipe 59 and enters the inner barrel 2, it first passes through the filter plate 1 in the inner barrel 2 and falls onto the inclined plate 10 located below the filter plate 1. Due to the slope of the inclined plate 10, the water flows down the slope of the inclined plate 10 due to its own weight. Since the inclined plate 10 is provided with a water leakage hole 11, one side of the hole wall of the water leakage hole 11 is in contact with the inner surface of the inner barrel 2, so that the water sample that slides down the inclined plate 10 passes through the water leakage hole 11 and then slides down the inner surface of the inner barrel 2. By utilizing the wall adhesion effect of water, the phenomenon of water sample entering the inner barrel 2 generating air bubbles and affecting the detection accuracy is reduced.

[0139] In one embodiment of the present invention, a dust cover 12 is hinged to the upper surface of the inner barrel 2;

[0140] By adopting the above technical solution, a dust cover 12 is hinged to the upper surface of the inner barrel 2, and a hole is made in the dust cover 12 to allow the No. 2 water inlet pipe 59 to pass through the hole in the dust cover 12, thereby reducing the contact between the inner barrel 2 and the external environment, and thus reducing the entry of impurities in the air into the inner barrel 2 and affecting the detection accuracy.

[0141] As one embodiment of the present invention, the bottom of the inner barrel 2 is provided with a drain outlet 13, and a drain pipe 14 is rotatably connected to the surface of the drain outlet 13. The drain pipe 14 passes through the outer barrel 3 and extends to the outside of the outer barrel 3.

[0142] In one embodiment of the present invention, a rubber stopper 15 is provided inside the drain pipe 14;

[0143] By adopting the above technical solution, during rinsing and sampling, the drain pipe 14 is blocked with a rubber stopper 15. After one rinsing and sampling, the staff removes the rubber stopper 15 from the drain pipe 14, and the water in the inner barrel 2 is discharged from the drain pipe 14.

[0144] Furthermore, by setting a rotatable connection between the connecting pipe and the surface of the drain outlet 13, the inner barrel 2 will not interfere with the drain pipe 14 when it rotates.

[0145] A mounting ring is fixedly connected to one end of the drain pipe 14 inside the drain outlet 13. The outer surface of the mounting ring is rotatably connected to the surface of the drain outlet 13, thereby achieving the rotatable connection between the drain pipe 14 and the drain outlet 13.

[0146] In one embodiment of the present invention, a slot 16 is provided in the rotating block 41, the surface of the slot 16 is threaded with the screw rod 42, and the depth of the slot 16 is greater than the length of the spiral pattern on the screw rod 42.

[0147] By adopting the above technical solution, since the rotating rod needs to rotate on the screw rod 42 while moving up and down, and the inner barrel 2 is fixedly connected to the upper surface of the rotating block 41, in order to ensure that the rotating block 41 has enough space for up and down movement, so as to ensure that the rotating block 41 can move up and down normally on the screw rod 42, a slot 16 is provided in the rotating block 41. The surface of the slot 16 is threaded with the screw rod 42, and the depth of the slot 16 is greater than the length of the spiral thread on the screw rod 42, so that the screw rod 42 can move up and down normally in the slot 16 of the rotating block 41.

[0148] Working principle: When rinsing the inner surface of the inner barrel 2, the end of the No. 1 water inlet pipe 58 away from the tee pipe 57 is placed into the river. The staff pushes the pressure rod 7 inward. The pressure rod 7 moves to one side of the inner barrel 2. When the pressure rod 7 moves to one side of the inner barrel 2, the end of the pressure rod 7 inside the outer barrel 3 is engaged in the installation groove 44 opened on the annular connecting block 43. At this time, the pressure rod 7 is connected to the cleaning component 4 as one unit.

[0149] At this time, the staff member steps on pedal 8, and pedal 8 moves downward, which drives the pressure rod 7 fixedly connected to it to move downward.

[0150] Since the pressure rod 7 is engaged with the mounting groove 44 on the annular connecting block 43 at this time, the pressure rod 7 exerts downward pressure on the annular connecting block 43 during its downward movement, causing the annular connecting block 43 to move downward.

[0151] The inner surface of the annular connecting block 43 is rotatably connected to the rotating block 41, so the annular connecting block 43 drives the rotating block 41 to move downward during its downward movement.

[0152] Since the rotating block 41 is connected to the screw rod 42 by a central screw drive, the rotating block 41 rotates in the forward direction as it moves downward on the screw rod 42.

[0153] The rotating block 41 rotates in the forward direction, causing the inner barrel 2, which is fixedly connected to the upper surface, to rotate in the forward direction.

[0154] At the same time, as the pressure rod 7 moves downward, it drives the pressure plate 45, which is slidably connected to it, to move downward.

[0155] The pressure plate 45 moves downward and presses against the airbag 51 and spring 47 below it. After the airbag 51 is compressed, the second one-way valve 511 at the exhaust port 510 opens, so that the internal gas is discharged from the exhaust port 510.

[0156] When the staff stops pressing the pedal 8 when it reaches the end point, the pedal 8 is no longer under pressure, so the spring 47 and the airbag 51 are no longer under the pressure and return to their elastic deformation.

[0157] During the process of spring 47 and airbag 51 restoring their elastic deformation, they drive pressure plate 45 to move upward;

[0158] The upward movement of the pressure plate 45 causes the pressure rod 7, which is slidably connected to it, to move upward.

[0159] The upward movement of the pressure rod 7 causes the pedal 8 and the annular connecting block 43 to move upward.

[0160] As the annular connecting block 43 moves upward, it drives the rotating block 41 to move upward.

[0161] Since the rotating block 41 is connected to the screw rod 42 by a central screw drive, the rotating block 41 rotates in the opposite direction as it moves upward on the screw rod 42.

[0162] This causes the rotating block 41 to rotate in the opposite direction, which in turn causes the inner barrel 2, which is fixedly connected to the upper surface, to rotate in the opposite direction.

[0163] At the same time, as the pressure on the airbag 51 decreases during the upward movement of the pressure plate 45, the airbag 51 gradually recovers its elastic deformation. During the process of recovering its elastic deformation, the airbag 51 needs to draw air from the perforated plug 54 at the air inlet 52.

[0164] When airbag 51 inhales, one-way valve 53 opens to allow inhalation.

[0165] During the process of air intake 52 provided on the airbag 51, the air pressure in the air intake pipe 55 at the air intake port decreases.

[0166] The decrease in air pressure inside the air inlet pipe 55 causes a decrease in air pressure inside the No. 1 water inlet pipe 58 and the No. 2 water inlet pipe 59 connected by the T-connector 57 at its upper end. As a result, the water flow in the river to be tested enters the No. 1 water inlet pipe 58 and gradually enters the No. 2 water inlet pipe 59 through the No. 1 water inlet pipe 58.

[0167] Water flows into the inner tub 2 through the second water inlet pipe 59, and with the forward and reverse rotation of the inner tub 2, the inner tub 2 is rinsed.

[0168] After one rinse is completed, drain the water in the inner tub 2 from the drain outlet 13. After the water is drained, close the drain outlet 13 and repeat the above actions to achieve multiple rinses of the inner tub 2.

[0169] After the washing is completed, the staff pulls the pressure rod 7 outward, and the pressure rod 7 disengages from the mounting groove 44 on the annular connecting block 43;

[0170] At this time, the pedal 8 is pressed repeatedly. Since the lever 7 is slidably connected to the pressure plate 45, the lever 7 is still connected to the pressure plate 45 after being pulled outward.

[0171] Thus, after the pressure bar 7 is subjected to pressure, it can still drive the pressure plate 45 to move downward again, and the downward movement of the pressure plate 45 can squeeze the airbag 51 again.

[0172] When the airbag 51 is compressed, the second one-way valve 511 at the exhaust port 510 opens, so that the internal gas is discharged from the exhaust port 510.

[0173] When the staff releases the pedal 8, the spring 47 and the airbag 51 are no longer subjected to the compressive force and return to their elastic deformation.

[0174] During the process of restoring elastic deformation, the airbag 51 needs to draw air from the perforated plug 54 at the air inlet 52;

[0175] When airbag 51 inhales, one-way valve 53 opens to allow inhalation.

[0176] During the process of air intake 52 provided on the airbag 51, the air pressure in the air intake pipe 55 at the air intake port decreases.

[0177] The reduced air pressure inside the air inlet pipe 55 causes a decrease in air pressure inside the No. 1 water inlet pipe 58 and the No. 2 water inlet pipe 59 connected by the T-connector 57 at its upper end. As a result, the water flow in the river to be tested enters the No. 1 water inlet pipe 58, and the water flow gradually enters the No. 2 water inlet pipe 59 through the No. 1 water inlet pipe 58, thus achieving sampling.

[0178] Thus, the staff pushes the pressure rod 7 inward, so that the pressure rod 7 engages with the annular connecting block 43. Then the staff repeatedly presses the pedal 8. The pedal 8, through the power transmission of the pressure rod 7, drives the cleaning component 4 and the sampling component 5 to cooperate with each other, causing the inner barrel 2 to rotate repeatedly in the forward and reverse directions, thereby washing the inner barrel 2.

[0179] After rinsing is completed, the staff pulls the pressure rod 7 outward to disengage the pressure rod 7 from the cleaning component 4. At this time, the staff continues to press the pedal 8 repeatedly. Since the pressure rod 7 is disengaged from the mounting groove 44 on the annular connecting block 43, the pressure rod 7 will not transmit power to the inner tub 2 at this time. The inner tub 2 will not rotate due to the up and down movement of the pressure rod 7. Thus, the inner tub 2 is in a stationary state at this time.

[0180] Then, repeatedly press the pedal 8, and the pedal 8 will drive the lever 7 to move up and down repeatedly.

[0181] As the pressure rod 7 moves up and down repeatedly, it drives the pressure plate 45 to repeatedly squeeze the air bag 51, which generates a large negative pressure at the air inlet 52 of the air bag 51. As a result, the water flows into the inner barrel 2 through the first water inlet pipe 58 and the second water inlet pipe 59 in sequence, thus realizing the collection of water samples.

[0182] There is no need for manual bending over to wash the inner tank 2 multiple times, nor is there a need for manual pulling of the sampling rope to pull the sampler out of the river to collect samples. Furthermore, there is no need for manual overcoming of the combined gravity of the sampler and the water sample, thereby reducing the workload of water sample collection and reducing the fatigue caused to staff during the water sample collection process.
