Description

Technical Field

[0001] The present invention relates to the technical field of water quality sampling, and particularly to a water quality sampling device for environmental monitoring. Background Art

[0002] Environmental monitoring refers to determining the environmental quality (or pollution degree) and its change trend by measuring representative values of factors affecting environmental quality. Environmental monitoring is to detect the content and emission amount of various substances that have an impact on humans and the environment, track the change of environmental quality, determine the environmental quality level, and provide a basis and guarantee for environmental management, pollution control and other work. For the detection of water quality, it is one of the important items in environmental monitoring. By detecting water, the environmental quality level around the water source and whether the water source is polluted can be determined.

[0003] When taking water quality samples for traditional environmental monitoring of water, a simple water bucket is generally used. During the use process, a rope is connected to the water bucket. Then, during the sampling work, according to the sampling requirements, the rope is lowered to make the water bucket hold the water sample, obtaining a certain sample for water quality determination. However, it is found in the actual use process that the existing water quality sampling equipment has a relatively simple form and a relatively simple structure. Therefore, when sampling, a lot of water debris and impurities will be mixed in the water sample, which affects the subsequent use of the water sample. At the same time, it is difficult for the water bucket to collect samples at different depths, reducing the use effect of the sampling equipment and bringing difficulties to the water quality monitoring work. Summary of the Invention

[0004] The object of the present invention is to solve the problems existing in the prior art that the existing water quality sampling equipment has a relatively simple form and a relatively simple structure. Therefore, when sampling, a lot of water debris and impurities will be mixed in the water sample, which affects the subsequent use of the water sample. At the same time, it is difficult for the water bucket to collect samples at different depths, reducing the use effect of the sampling equipment and bringing difficulties to the water quality monitoring work.

[0005] To achieve the above object, the present invention adopts the following technical solution: A water quality sampling device for environmental monitoring includes a sampling bucket. A connecting frame is fixedly connected to the surface of the sampling bucket. A water inlet nozzle is communicated with one side surface of the sampling bucket. A water outlet nozzle is arranged at the bottom position of the sampling bucket. A cover is threadedly connected to the surface of the water outlet nozzle. An auxiliary device is arranged inside the sampling bucket, and the auxiliary device filters and processes the water quality samples collected by the sampling bucket.

[0006] The effects achieved by the above components are as follows: When sampling the water quality of the environment using a sampling bucket, the rope is installed on the connecting frame, and then according to the required depth of the water sample to be taken, the sampling bucket is lowered into the water to the corresponding depth below the rope. After the sampling bucket sinks to the corresponding position, the auxiliary device is activated to open the water inlet nozzle of the sampling bucket to collect an appropriate water quality sample. At the same time, the auxiliary device filters the water sample collected by the sampling bucket, and then after the collection is completed, the sampling bucket is pulled out. Then, when testing the sample, the cover is opened, and an appropriate amount of sample is taken from the position of the water outlet nozzle.

[0007] Preferably, the auxiliary device includes a rotating rod, which is rotatably connected through the surface of the sampling bucket. A servo motor is fixedly connected to the bottom of the sampling bucket, and the output end of the servo motor is fixedly connected to one end of the rotating rod.

An electric telescopic rod is fixedly connected to the surface of the sampling bucket, and the output end of the electric telescopic rod is fixedly connected to a moving block, which is engaged with the groove of the limiting disk. A first filter screen and a second filter screen are fixedly connected to the inner wall of the sampling bucket, and the hole size of the first filter screen is larger than that of the second filter screen. A cleaning component is provided at the position of the arc surface of the sampling bucket where the first filter screen and the second filter screen are located, and the component assists in removing the impurities remaining inside the sampling bucket. A rotating cylinder is rotatably connected to the arc surface of the rotating rod, and a number of evenly distributed arc-shaped plates are fixedly connected to the arc surface of the rotating cylinder, and a number of holes are provided on the surface of the arc-shaped plates.

An installation rod is fixedly connected to the inner wall of the sampling bucket, and a gear is rotatably connected to one end of the installation rod, and the gear is engaged with the tooth disk. Three rotating rods are rotatably connected to the sides of the first filter screen and the second filter screen close to each other and are evenly distributed in a circumferential manner. A rotating plate with holes is fixedly connected to the arc surfaces of the three rotating rods. Rollers are respectively fixedly connected to the arc surfaces of the three rotating rods, and a belt is provided on the arc surfaces of the rollers on the three rotating rods. A conveyor belt is provided on the arc surfaces of the rotating rod and one of the rotating rods. A number of evenly staggered flow guiding plates are provided at the position between the second filter screen and the bottom of the inner wall of the sampling bucket, and a notch is provided on one side of the flow guiding plate, and a number of stripe protrusions are provided on the surface of the flow guiding plate. A protection component is provided at the position of the water outlet nozzle on the inner wall of the sampling bucket, and the protection component takes protective measures for the water quality sample in the sampling bucket when obtaining the water quality sample.

[0008] The effects achieved by the above components are as follows: When collecting environmental water samples, the sampling bucket can better ensure the cleanliness of the water sample, without excessive impurities mixing in, which may affect subsequent use and detection. This improves the accuracy and reliability of the detection results, as well as the usage effect and practicality of the sampling bucket.

[0009] Preferably, the cleaning component includes four processing frames. The four processing frames are grouped in pairs. The processing frames in the same group are fixedly connected to the surface of the sampling bucket and are respectively located on one side of the first filter screen and the second filter screen. Covers are respectively clamped on the surfaces of the processing frames in the same group. A connecting plate is fixedly connected to the surface of the cover. A screw rod is inserted through the surface of the connecting plate. The screw rod is fixedly connected to the surface of the sampling bucket. A nut is threadedly connected to the arc surface of the screw rod.

[0010] The effects achieved by the above components are as follows: When the water quality sample in the sampling bucket is completely taken out and used, rotate the nuts on both sides of the sampling bucket to separate the nuts from the connecting plate and remove them from the screw rod. Then, remove the cover from the opening of the processing frame. At this time, take out the sundries and impurities in the sampling bucket, restart the servo motor, and at the same time, use clean water to rinse the inside of the sampling bucket, so as to completely remove the intercepted and filtered impurities inside the sampling bucket, ensuring the next sampling use of the sampling bucket. At this time, when the sampling bucket is in use, it can better ensure the cleanliness and pollution - free inside, so as to ensure the accuracy and reliability of the sample when sampling water quality, improving the usage effect and practicality of the sampling bucket.

[0011] Preferably, the protection component includes a mounting frame. The mounting frame is fixedly connected to the inner wall of the sampling bucket. A sliding rod is slidably connected through the surface of the mounting frame. One end of the sliding rod is fixedly connected to a protection plug. An auxiliary frame is fixedly connected to the surface of the protection plug. The protection plug is slidably inserted into the inner wall of the water outlet nozzle. A spring is sleeved on the arc surface of the sliding rod. The two ends of the spring are respectively fixedly connected to the surfaces of the mounting frame and the protection plug.

[0012] The effect achieved by the above components is: when using the sampling bucket to take out the corresponding water quality sample and take it out of the water surface, and using the test tube to take out an appropriate amount of sample, first remove the cover on the water outlet, then insert the test tube into the inner wall of the water inlet and outlet, and continue to slide, and in the process of sliding, it contacts and squeezes the auxiliary frame fixedly connected to the protective plug, and then continues to push and squeeze upward. In the process of squeezing and pushing, the protective plug is gradually pushed away from the inner wall of the water outlet, so that the sliding rod fixedly connected to the protective plug slides on the inner wall of the mounting frame, and a gap appears. At this time, the water sample at the bottom of the inner wall of the sampling barrel will enter the test tube through the gap. After taking out an appropriate amount of sample, the test tube is pulled out of the water outlet. At this time, the protective cover will be pushed toward the port position of the water outlet under the elastic force of the spring until the protective cover slides back into the water outlet to block and seal it. At this time, the sampling barrel can be more convenient and quick when performing appropriate amount of water sample extraction and testing, making the use of water samples more sufficient, and further improving the use effect and functionality of the sampling barrel.

[0013] Preferably, a protective sleeve is sleeved on the arc surface of the rotating rod, and the protective sleeve cover is arranged on the surface of the gear and the gear plate.

[0014] The effect achieved by the above components is: through the setting of the protective cover, after water enters the sampling barrel, the meshing of the gear tooth plate is submerged in water, and debris and impurities are not easily entangled or entangled on the gears and gear plates, thereby maintaining the rotation of the device structure in a normal form, and is not prone to jamming or freezing, so that larger debris and impurities can be better intercepted and processed.

[0015] Preferably, a limiting rod is fixedly connected to the surface of the sampling barrel, and the limiting rod is slidably connected to the surface of the moving block.

[0016] The effect achieved by the above components is: through the setting of the limit rod, the electric telescopic rod drives the moving block to move up and down, and the moment the moving block is stuck in the groove on the limit plate, the position of the moving block is guaranteed to be stable, and the electric telescopic rod is not easily forced to rotate, causing damage to the internal mechanical structure of the electric telescopic rod, thereby making it less likely for abnormal situations to occur during the use of the moving block.

[0017] Preferably, bearings are fixedly connected to the arc surfaces of the three rotating rods respectively, the inner rings of the bearings are fixedly connected to the arc surfaces of the rotating rods, and the outer rings of the bearings are fixedly connected to the surface of the second filter screen.

[0018] The effect achieved by the above components is: through the setting of the bearing, the contact between the rotating rod and the second filter screen is reduced when the rotating rod rotates, so that rotational wear is less likely to occur between the rotating rod and the second filter screen, ensuring the normal use of the rotating rod and the second filter screen, and better stirring and intercepting relatively fine impurities.

[0019] Preferably, a counterweight sleeve is fixedly connected to the surface of the sampling bucket, and the counterweight sleeve covers the surface of the servo motor.

[0020] The effects achieved by the above components are as follows: Through the setting of the counterweight sleeve, when the sampling bucket is immersed in water along with the rope below, it can better ensure a vertical state, is not prone to tilting and shaking, so that the samples taken below are more accurate and reliable. At the same time, the configuration block can better protect the servo motor outside the sampling bucket, so that the output end position of the servo motor is not easily entangled and trapped by sundries in the water, affecting the normal use of the sampling bucket.

[0021] Preferably, a connecting rope is fixedly connected to the surface of the nut, and the other end of the connecting rope is fixedly connected to the arc surface of the sampling bucket.

[0022] The effects achieved by the above components are as follows: Through the setting of the connecting rope, the nut is more convenient to pick up during use, and a stable connection relationship with the sampling bucket is ensured. It is not easy for the nut to fall and be lost during the disassembly and assembly of the cover plate and the use of the nut, ensuring the integrity and normal use effect of the sampling bucket, and better clearing the impurities and dirt intercepted and filtered inside the sampling bucket.

[0023] Preferably, a sealing ring is fixedly connected to the arc surface of the protective plug, and the sealing ring is a rubber ring.

[0024] The effects achieved by the above components are as follows: Through the setting of the sealing ring, the protective plug fits more closely and is better adapted to the inner wall of the water outlet nozzle, and it is not easy to generate gaps. Therefore, when the protective plug is inside the water outlet nozzle, it can better intercept the water quality inside the sampling bucket, and it is not easy to have water stains leak and drip when the cover is opened, improving the use effect of the protection component.

[0025] In summary, the beneficial effects of the present invention are as follows:

[0026] In the present invention, when the sampling bucket is used to collect environmental water samples, it can accurately collect samples at different depth positions, can better ensure the cleanliness of the water sample, and there is no excessive mixing of impurities, which affects subsequent use and detection, improving the accuracy and reliability of the detection results, and also improving the use effect and practicability of the sampling bucket.

[0027] In the present invention, when the sampling bucket is used, it can better ensure the cleanliness and pollution-free inside, so as to ensure the accuracy and reliability of the sample when sampling water quality, improving the use effect and practicability of the sampling bucket.

[0039] Refer to Figure 1As shown in the figure, the present invention provides a technical solution: a water quality sampling device for environmental monitoring, including a sampling bucket 1. A connecting frame 2 is fixedly connected to the surface of the sampling bucket 1. A water inlet nozzle 3 is communicated with one side surface of the sampling bucket 1. A water outlet nozzle 8 is arranged at the bottom position of the sampling bucket 1. A cover 7 is threadedly connected to the surface of the water outlet nozzle 8. An auxiliary device 4 is arranged inside the sampling bucket 1. The auxiliary device 4 filters and processes the water quality samples collected by the sampling bucket 1. When sampling the environmental water quality using the sampling bucket 1, install the rope on the connecting frame 2, and then according to the required depth of the water sample to be taken, lower the rope so that the sampling bucket 1 enters the water at the corresponding depth. After the sampling bucket 1 sinks to the corresponding position, start the auxiliary device 4 to open the water inlet nozzle 3 of the sampling bucket 1 to collect the appropriate water quality samples. At the same time, the auxiliary device 4 filters the water samples collected by the sampling bucket 1. Then, after the collection is completed, pull out the sampling bucket 1. Then, when testing the sample, open the cover 7 and take an appropriate amount of sample from the position of the water outlet nozzle 8.

[0040] Referring to Figure 1 - Figure 7 As shown in the figure, in this implementation scheme: The auxiliary device 4 includes a rotating rod 41. The rotating rod 41 is rotatably connected through the surface of the sampling bucket 1. A servo motor 42 is fixedly connected to the bottom of the sampling bucket 1. The output end of the servo motor 42 is fixedly connected to one end of the rotating rod 41. A thread is provided at one end of the rotating rod 41. A trapezoidal block 43 is threadedly connected to the threaded position of the rotating rod 41. A limiting disk 44 is fixedly connected to one side surface of the trapezoidal block 43. A number of uniformly distributed grooves are provided on the arc surface of the limiting disk 44. An electric telescopic rod 46 is fixedly connected to the surface of the sampling bucket 1. The output end of the electric telescopic rod 46 is fixedly connected to a moving block 45. The moving block 45 is engaged with the groove of the limiting disk 44. A first filter screen 47 and a second filter screen 48 are fixedly connected to the inner wall of the sampling bucket 1. And the hole size of the first filter screen 47 is larger than the hole size of the second filter screen 48. A cleaning component 5 is arranged at the position of the arc surface of the sampling bucket 1 where the first filter screen 47 and the second filter screen 48 are located. The component assists in removing the impurities remaining inside the sampling bucket 1. A rotating cylinder 49 is rotatably connected to the arc surface of the rotating rod 41. A number of uniformly distributed arc-shaped plates 410 are fixedly connected to the arc surface of the rotating cylinder 49. And a number of holes are provided on the surface of the arc-shaped plate 410. A turntable frame 411 is fixedly connected to the arc surface of the rotating rod 41. The turntable frame 411 is in contact with the surface of the first filter screen 47. Tooth disks 412 are respectively fixedly connected to the sides of the rotating cylinder 49 and the turntable frame 411 that are close to each other. An installation rod 413 is fixedly connected to the inner wall of the sampling bucket 1. One end of the installation rod 413 is rotatably connected to a gear 414. The gear 414 is engaged with the tooth disk 412. Three rotating rods are rotatably connected to the sides of the first filter screen 47 and the second filter screen 48 that are close to each other and are evenly distributed in a circumferential manner

[0041] 415. On the arc surfaces of the three rotating rods 415, there is a fixedly connected rotating plate 416 with holes. On the arc surfaces of the three rotating rods 415, there are respectively fixedly connected rollers 418. And on the arc surfaces of the rollers 418 on the three rotating rods 415, there is a belt 417. Between the rotating rod 41 and the arc surface of one of the rotating rods 415, there is a conveyor belt 419. Inside the sampling bucket 1, at the position between the second filter screen 48 and the bottom, there are several uniformly and staggeredly distributed flow guiding plates 420. And on one side of the flow guiding plate 420, there is a notch. On the surface of the flow guiding plate 420, there are several stripe protrusions. Inside the sampling bucket 1, at the position of the water outlet nozzle 8, there is a protection component 6. When the protection component 6 obtains the water quality sample in the sampling bucket 1, it takes protective measures for the sample water quality. When sampling the environmental water quality using the sampling bucket 1, install the rope on the connecting frame 2, and then according to the required depth of the water sample to be taken, lower the rope so that the sampling bucket 1 enters the water at the corresponding depth. After the sampling bucket 1 sinks to the corresponding position, start the servo motor 42 to make the rotating rod 41 rotate. Because the moving block 45 is stuck in the groove of the limiting disk 44, the trapezoidal block 43 rises driven by the rotating rod 41. At the same time, start the electric telescopic rod 46 to make the speed of the electric telescopic rod 46 driving the trapezoidal block 43 the same as the moving speed of the moving block 45, so that the moving block 45 moves upward stably, exposing the gap at the position of the water inlet nozzle 3. At this time, water will enter the sampling bucket 1 from the gap. Then the water will pass through the holes of the first filter screen 47 and enter the lower part. Larger sundries and impurities will be intercepted. At the same time, the turntable frame 411 will rotate and rub against the surface of the first filter screen 47 in a rotating manner, scraping the impurities attached to the first filter screen 47 to ensure the continuous falling of water. Because the gear 414 drives the gears 414 on the rotating disk and the rotating cylinder 49 to mesh and rotate at the same time, the rotating cylinder 49 will drive the arc-shaped plate 410 to rotate. And during the rotation process, the impurities will be intercepted and fished out. Then the water will fall on the second filter screen 48 and intercept and process smaller sundries and impurities. Then through the connection and drive of the conveyor belt 419 and the belt 417, the rotating rod 415 will rotate, driving the rotation of the rotating plate 416. Then the water sample will fall on the inclined flow guiding plate 420 below and continuously fall at the notch position until the collection is completed. Then after the collection is completed, pull out the sampling bucket 1. Then when testing the sample, open the cover 7 and take an appropriate amount of sample from the position of the water outlet nozzle 8. At this time, when the sampling bucket 1 collects and samples environmental water samples, it can better ensure the cleanliness of the water sample, without excessive impurities mixing in, affecting the subsequent use and detection, improving the accuracy and reliability of the detection result, and also improving the use effect and practicability of the sampling bucket 1.

[0042] Refer to Figure 1 and Figure 9As shown, in this implementation: The cleaning component 5 includes four processing boxes 51. The four processing boxes 51 are grouped in pairs. The processing boxes 51 in the same group are fixedly connected to the surface of the sampling bucket 1 and are respectively located on one side of the first filter screen 47 and the second filter screen 48. The surfaces of the processing boxes 51 in the same group are respectively clamped with cover plates 53. A connecting plate 54 is fixedly connected to the surface of the cover plate 53. A screw rod 52 is inserted through the surface of the connecting plate 54. The screw rod 52 is fixedly connected to the surface of the sampling bucket 1. A nut 55 is threadedly connected to the arc surface of the screw rod 52. When the water quality sample in the sampling bucket 1 is taken out and used up completely, rotate the nuts 55 on both sides of the sampling bucket 1 to separate the nuts 55 from the connecting plate 54 and remove them by turning back from the screw rod 52. Then remove the cover plate 53 from the opening of the processing box 51. At this time, take out the sundries and impurities in the sampling bucket 1, and restart the servo motor 42. At the same time, use clean water to wash the inside of the sampling bucket 1, so as to completely remove the intercepted and filtered impurities in the sampling bucket 1, ensuring the next sampling use of the sampling bucket 1. At this time, when the sampling bucket 1 is in use, it can better ensure that the inside is clean and free of dirt, so as to ensure the accuracy and reliability of the sample when sampling water quality, improving the use effect and practicability of the sampling bucket 1.

[0043] Referring to Figure 1 and Figure 5 As shown, in this implementation: The protection component 6 includes a mounting frame 61. The mounting frame 61 is fixedly connected to the inner wall of the sampling bucket 1. A sliding rod 62 is slidably connected through the surface of the mounting frame 61. One end of the sliding rod 62 is fixedly connected to a protection plug 63. An auxiliary frame 64 is fixedly connected to the surface of the protection plug 63. The protection plug 63 is slidably inserted into the inner wall of the water outlet nozzle 8. A spring 65 is sleeved on the arc surface of the sliding rod 62. The two ends of the spring 65 are respectively fixedly connected to the surfaces of the mounting frame 61 and the protection plug 63. When using the sampling bucket 1 to take out the corresponding water quality sample and take it out of the water surface, and using a test tube to take an appropriate amount of sample, first remove the cap 7 on the water outlet nozzle 8, then insert the test tube into the inner wall of the water inlet and outlet nozzle 8 and keep sliding. During the sliding process, it contacts and presses the auxiliary frame 64 fixedly connected to the protection plug 63, and then continues to push and press upward. During the pushing and pressing process, the protection plug 63 is gradually pushed away from the inner wall of the water outlet nozzle 8, so that the sliding rod 62 fixedly connected to the protection plug 63 slides in the inner wall of the mounting frame 61, and a gap appears. At this time, the water sample at the bottom of the inner wall of the sampling bucket 1 will enter the test tube through the gap. After taking an appropriate amount of sample, pull out the test tube from the water outlet nozzle 8. At this time, the protection cover will be pushed towards the port position of the water outlet nozzle 8 under the elastic force of the spring 65 until the protection cover slides back into the water outlet nozzle 8 again and blocks it. At this time, when the sampling bucket 1 is used to extract and detect an appropriate amount of water sample, it can be more convenient and fast, making the use of the water sample more sufficient, and further improving the use effect and functionality of the sampling bucket 1.

[0044] Referring to Figure 1 andFigure 2 As shown, in this embodiment: a protective sleeve 421 is sleeved on the arc surface of the rotating rod 41, and the protective sleeve 421 covers the surface of the gear 414 and the toothed disc 412. Through the setting of the protective sleeve 421, after water enters the sampling barrel 1, the meshing of the gear 414 and the toothed disc 412 is submerged in water, and foreign matter and impurities are not easily entangled or entangled on the gear 414 and the gear 414 disc, thereby maintaining the rotation of the device structure in a normal form, and is not prone to jamming or deadlocking, and can better intercept and process larger foreign matter and impurities.

[0045] Reference Figure 2 As shown, in the present embodiment: a limiting rod 422 is fixedly connected to the surface of the sampling barrel 1, and the limiting rod 422 is slidably connected to the surface of the moving block 45. Through the setting of the limiting rod 422, the electric telescopic rod 46 drives the moving block 45 to move up and down, and the moment the moving block 45 is stuck into the groove on the limiting plate 44, the position of the moving block 45 is guaranteed to be stable, and the electric telescopic rod 46 is not easily forced to rotate, causing damage to the internal mechanical structure of the electric telescopic rod 46, thereby making it less likely for abnormal situations to occur when the moving block 45 is used.

Through the arrangement of the bearing 423, the contact between the rotating rod 415 and the second filter screen 48 is reduced when the rotating rod 415 rotates, so that rotational wear is not likely to occur between the rotating rod 415 and the second filter screen 48, thereby ensuring the normal use of the rotating rod 415 and the second filter screen 48, and better stirring and intercepting of relatively fine impurities.

Through the setting of the counterweight sleeve 424, the sampling barrel 1 can better maintain a vertical state when immersed in the water under the rope, and is not prone to tilting and shaking, so that the samples taken below are more accurate and reliable. At the same time, the configuration block can better protect the servo motor 42 outside the sampling barrel 1, so that the output end position of the servo motor 42 is not easily entangled and trapped by debris in the water, affecting the normal use of the sampling barrel 1.

Through the setting of the connecting rope 56, the nut 55 is more convenient to pick up during use, ensuring a stable connection relationship with the sampling bucket 1. It is not easy for the nut 55 to fall off or be lost during the disassembly and assembly of the cover plate 53 and the use of the nut 55, ensuring the integrity of the sampling bucket 1 and its normal use effect, and better clearing the impurities and dirt intercepted and filtered inside the sampling bucket 1.

[0049] Refer to Figure 1 and Figure 4 As shown, in this implementation: A sealing ring 66 is fixedly connected to the arc surface of the protective plug 63. The sealing ring 66 is a rubber ring. Through the setting of the sealing ring 66, the protective plug 63 fits more closely and is better adapted to the inner wall of the water outlet nozzle 8, and it is not easy to generate gaps. Thus, when the protective plug 63 is inside the water outlet nozzle 8, it can better intercept the water quality inside the sampling bucket 1, and it is not easy for water stains to leak and drip when the cover 7 is opened, improving the use effect of the protection component 6.

[0050] Working principle: When sampling the environmental water quality using the sampling bucket 1, install the rope on the connecting frame 2, and then according to the required depth of the water sample to be taken, lower the rope so that the sampling bucket 1 enters the water at the corresponding depth. After the sampling bucket 1 sinks to the corresponding position, start the servo motor 42 to make the rotating rod 41 rotate. Since the moving block 45 is stuck in the groove of the limit disc 44, the trapezoidal block 43 rises driven by the rotating rod 41. At the same time, start the electric telescopic rod 46 to make the speed at which the electric telescopic rod 46 drives the trapezoidal block 43 the same as the moving speed of the moving block 45, so that the moving block 45 moves upward stably, exposing the gap at the position of the water inlet nozzle 3. At this time, water will enter the sampling bucket 1 through the gap. Then the water will pass through the holes of the first filter screen 47 and enter the lower part, and larger sundries and impurities will be intercepted. At the same time, the turntable frame 411 will rotate, generating rotational friction with the surface of the first filter screen 47 to scrape the impurities attached to the first filter screen 47, ensuring the continuous flow of water. Since the gear 414 drives the gears on the rotating disc and the rotating cylinder 49 to mesh and rotate simultaneously, the rotating cylinder 49 will drive the arc-shaped plate 410 to rotate, and during the rotation process, intercept and lift the impurities. Then the water will fall on the second filter screen 48 to intercept and process smaller sundries and impurities. Then, driven by the connection of the conveyor belt 419 and the belt 417, the rotating rod 415 rotates, driving the rotation of the rotating plate 416. Then the water sample will fall on the inclined guide plate 420 below and continuously fall at the notch position until the collection is completed. After the collection is completed, pull out the sampling bucket 1. Then, during the sample detection, open the cover 7, insert the test tube into the inner wall of the water inlet and outlet nozzle 8, and continuously slide it. During the sliding process, it contacts and presses against the auxiliary frame 64 fixedly connected to the protective plug 63, and then continues to push and press upward. During the pushing and pressing process, gradually push the protective plug 63 away from the inner wall of the water nozzle 8, so that the sliding rod 62 fixedly connected to the protective plug 63 slides in the inner wall of the mounting frame 61, and a gap appears. At this time, the water sample at the bottom of the inner wall of the sampling bucket 1 will enter the test tube through the gap. After taking an appropriate amount of sample, pull out the test tube from the water outlet nozzle 8. At this time, the protective cover will be pushed towards the port position of the water outlet nozzle 8 under the elastic force of the spring 65 until the protective cover slides back into the water outlet nozzle 8 and blocks it. When the water quality sample in the sampling bucket 1 is completely taken out and used, rotate the nuts 55 on both sides of the sampling bucket 1 to separate the nuts 55 from the connecting plate 54 and remove them from the screw rod 52, and then remove the cover plate 53 from the opening of the treatment box 51. At this time, take out the sundries and impurities in the sampling bucket 1, and restart the servo motor 42. At the same time, use clean water to rinse the inside of the sampling bucket 1, so as to completely remove the intercepted and filtered impurities inside the sampling bucket 1, ensuring the next sampling use of the sampling bucket 1. At this time, when the sampling bucket 1 is collecting and sampling environmental water samples, it can better ensure the cleanliness of the water sample, without excessive impurities mixing in, affecting the subsequent use and detection, and improving the accuracy and reliability of the detection results.It also improves the usage effect and practicality of the sampling bucket 1.,
