Description

Technical Field

[0001] The invention relates to the technical field of printing and dyeing wastewater sampling, and in particular to a water body detection sampling device based on a printing and dyeing wastewater treatment system. Background Art

[0002] In the printing and dyeing wastewater treatment system, water body detection and sampling equipment is a key tool to ensure the wastewater treatment effect and monitor water quality changes. This type of equipment can automatically or semi-automatically complete the task of collecting samples from water bodies at different treatment stages, and provide a scientific basis for adjusting treatment process parameters and evaluating treatment efficiency by analyzing the content of harmful substances, pH value, color and other indicators in the samples. This not only helps to protect the environment, but also guides enterprises to reduce resource waste and improve production efficiency.

[0003] The patent with the patent publication number of CN116558880A discloses a multifunctional sampling device for the treatment of printing and dyeing wastewater, including a vertical water intake pipe, a conical guide pipe formed at the lower end of the water intake pipe, a cylindrical insert pipe formed at the lower end of the guide pipe, a conical counterweight head is arranged below the water intake pipe, a vertical screw is formed on the upper end face of the counterweight head, the screw is inserted in the water intake pipe and is inserted with a conical sealing head, the sealing head is inserted in the pipe mouth of the insert pipe; the screw is respectively inserted with an upper limit plate and a lower limit plate, the upper limit plate and the lower limit plate are respectively inserted and fixed in the water intake pipe, a limit block is inserted and fixed on the screw between the upper limit plate and the lower limit plate, and the limit block abuts against the lower end face of the upper limit plate. This sampling device is a sewage collection sampler, which can be adjusted, not only to meet the collection of surface water samples in the sewage treatment pool, but also to meet the collection of water samples of different water layers in the sewage treatment pool after adjustment.

[0004] The prior art has the following defects:

[0005] Unable to flush the sampling pipeline and the inside of the pump body in time during multiple sampling processes: The sewage in the printing and dyeing wastewater treatment system has some differences in characteristics at different stages and different water depths. Therefore, it is necessary to sample at different depths of the water body, such as the surface, middle and bottom layers, so as to fully reflect the water quality of the entire water body. Since the printing and dyeing wastewater contains complex components such as dyes and chemical additives, the residual dyes, chemical additives and other substances in the process of multiple sampling will contaminate the new samples and affect the accuracy of the test results. Therefore, it is necessary to set up a device for timely flushing the sampling pipeline and the inside of the pump body to prevent the residual substances in the previous sample from contaminating the new sample, ensure the accuracy and representativeness of each sampling, extend the service life of the equipment, and ensure the normal operation of the system, thereby achieving the effect of improving the purity of the sample and the accuracy of the test.

[0006] Unable to sample sewage in the middle part of the pool: The sewage in the middle part of the pool and the sewage at the edge are different in dissolved oxygen content, temperature, suspended matter and sediment, chemical composition and biological activity. The central part usually has lower dissolved oxygen, more uniform temperature, less suspended matter, and is less affected by external pollution, while the edge has higher dissolved oxygen, larger temperature difference, more suspended matter and sediment, more complex chemical composition, and higher biological activity. Existing equipment can generally only sample sewage at the edge of the pool, but cannot sample sewage in the middle part of the pool, resulting in incomplete data, thus misjudging the degree of pollution and treatment effect, affecting the formulation and implementation of treatment plans. Therefore, it is necessary to set up a device with extendable sampling points to sample different water layers at any position of the pool, so as to have a more comprehensive understanding of the overall water quality, accurately assess the degree of pollution and treatment effect, thereby achieving the effect of improving the scientificity and effectiveness of environmental management. Summary of the invention

[0007] In view of the problems in the existing technology that the sampling pipe and the inside of the pump body cannot be flushed in time during multiple sampling processes and the sewage in the middle part of the pool cannot be sampled, a water body detection sampling equipment based on the printing and dyeing wastewater treatment system is proposed.

[0008] The present application provides a water body detection sampling device based on a printing and dyeing wastewater treatment system, the purpose of which is to: through the provision of a sample storage mechanism, a pump tube assembly and a sampling mechanism, the sampling pipeline and the inside of the pump body can be flushed in time to achieve the effect of improving the purity of the sample and the accuracy of the detection; through the provision of an extension assembly, different water layers at any position of the pool can be sampled, thereby achieving the effect of improving the scientificity and effectiveness of environmental management.

[0009] The technical solution of the present invention is: a water body detection sampling device based on a printing and dyeing wastewater treatment system, comprising a mobile base, a support base fixedly installed on the top of the mobile base, a sample storage mechanism arranged above the support base, a pump tube assembly and an extension assembly, and a sampling mechanism arranged on one side of the pump tube assembly and the extension assembly, the sample storage mechanism comprising a sample storage box fixedly installed on the top of the support base and a rotating cylinder, and a rotating assembly is arranged inside the sample storage box;

[0012] The above scheme is adopted, through the sample storage mechanism, three sample storage tubes are installed for each sampling group, and samples are taken from the surface, middle and bottom layers of a point in the sewage pool respectively. The sample storage tubes are installed in sequence in the rotating outer frame, and clean water is stored in two of the sample storage tubes for cleaning during the sampling process. The limit blocks on both sides of the sample storage tube are aligned with the limit grooves in the insertion grooves and inserted, so that the second opener and closeer fall on the first opener and closeer. At this time, the second opener and closeer are in a misaligned state with the first opener and closeer, and the flow port and the inside of the sample storage tube are not circulated. Then the rotating cylinder is operated, and the output end of the rotating cylinder drives the rotating outer frame to rotate in the sample storage box through the card slot, and the empty sample storage tube is facing the centrifugal water pump, and then the sample storage tube is rotated in each insertion slot to align the second opener and closeer with the first opener and closeer, so that the inside of the sample storage tube is connected with the extrusion tube through the flow port, thereby providing a container for sampling and flushing, and is converted by the rotating cylinder to prevent the residual substances in the previous sample from contaminating the new sample, so as to achieve the effect of improving the purity of the sample and the accuracy of detection.

[0013] Furthermore, the pump tube assembly includes a centrifugal water pump fixedly mounted on the top of the support base, an outer wall of the centrifugal water pump is fixedly connected to an extrusion pipe, and one end of the extrusion pipe away from the centrifugal water pump is connected to the flow port by penetrating the sample storage box.

[0014] Furthermore, a suction pipe is fixedly connected to the bottom of the centrifugal water pump, and one end of the suction pipe away from the centrifugal water pump is fixedly connected to a corrosion-resistant water pipe by penetrating a support base. An automatic hose reel is fixedly installed between the support base and the mobile base, and the corrosion-resistant water pipe is wound inside the automatic hose reel.

[0015] By adopting the above scheme, through the set pump pipe assembly, when sampling, the centrifugal water pump is operated, the centrifugal water pump provides suction to take samples through the suction pipe and the corrosion-resistant water pipe by the sampling mechanism, and transports them to the empty sample storage tube. When flushing, the centrifugal water pump is operated in reverse to draw clean water from the sample storage tube to flush the pipe and the pump, thereby providing power for sampling and flushing.

[0016] Furthermore, the sampling mechanism includes a wire drum fixedly mounted on one end of the extension component, the output end of the wire drum is fixedly connected to a hoist, and the bottom of the hoist is fixedly connected to a diving component.

[0017] Furthermore, the submersible component includes a wastewater cylinder fixedly connected to the bottom of the hoist, the inner wall of the wastewater cylinder is fixedly connected to a suction cylinder, and one end of the corrosion-resistant water pipe away from the centrifugal water pump is fixedly connected to the inner wall of the suction cylinder.

[0018] Furthermore, a filter plate is clamped on the inner wall of the water absorption cylinder, and a first rolling ball is rollingly connected to the inner wall of the water absorption cylinder.

[0020] The above scheme is adopted, through the sampling mechanism that is set up, when sampling the surface layer, the wire drum is operated to place the water suction cylinder and the wastewater cylinder into the surface layer of the water through the hoisting device. When sampling the middle layer, the wire drum continues to be operated to lower the submersible component. During the sampling process, the centrifugal water pump provides suction to take samples from the water suction cylinder. At this time, the first rolling ball in the water suction cylinder is separated from the bottom of the water suction cylinder, allowing the sewage to enter the water suction cylinder and be transported to the empty sample storage tube through the filtration of the filter plate. During the flushing process, the flushing water flows through the pipeline to reach the water suction cylinder, squeezing the first rolling ball to seal the bottom of the water suction cylinder, thereby preventing the cleaning water from causing secondary pollution to the sewage pool. The second rolling ball is squeezed to clear the partition cylinder, allowing the cleaning water to flow into the wastewater cylinder, thereby providing a sampling and flushing channel and carrier.

[0021] Furthermore, the extension assembly includes an extension frame fixedly installed on the top of the support base, the inner wall of the extension frame is slidably connected to a plurality of extension plates, a locking hinge is fixedly installed between two adjacent extension plates, the outer wall of the outermost extension plate is hinged to a mounting frame through a locking hinge, and the outer wall of the mounting frame is hinged to the top of the wire reel.

[0022] Furthermore, a water pipe swing groove is provided on the inner wall of the movable base, and the inner wall of the water pipe swing groove is slidably connected to the outer wall of the corrosion-resistant water pipe.

[0023] By adopting the above scheme, by pulling out the extension plate from the extension frame, multiple extension plates can form brackets of different lengths and be fixed by locking hinges. Since the end points of the extension plate are on both sides of the extension frame, the corrosion-resistant water pipe is driven to tilt, and the water pipe swing groove in the mobile base adapts to its tilted state. In this way, different water layers at any position of the pool can be sampled, thereby achieving the effect of improving the scientificity and effectiveness of environmental management.

[0024] Beneficial effects of the present invention:

[0025] 1. Through the sample storage mechanism, three sample storage tubes are installed in each sampling group, and samples are taken from the surface, middle and bottom layers of a point in the sewage pool respectively. The sample storage tubes are installed in the rotating outer frame in sequence, and clean water is stored in two of the sample storage tubes for cleaning during the sampling process. The limit blocks on both sides of the sample storage tube are aligned with the limit grooves in the insertion groove and inserted, so that the second opener and closeer fall on the first opener and closeer. At this time, the second opener and closeer are in a misaligned state with the first opener and closeer, and the flow port and the inside of the sample storage tube are not circulated. Then the rotating cylinder is operated, and the output end of the rotating cylinder drives the rotating outer frame to rotate in the sample storage box through the card slot, and the empty sample storage tube is facing the centrifugal water pump, and then the sample storage tube is rotated in each insertion groove to align the second opener and closeer with the first opener and closeer, so that the inside of the sample storage tube is connected with the extrusion tube through the flow port, thereby providing a container for sampling and flushing, and is converted by the rotating cylinder to prevent the residual substances in the previous sample from contaminating the new sample, so as to achieve the effect of improving the purity of the sample and the accuracy of detection.

[0026] 2. Through the set extension components, when it is necessary to sample the middle point of the water pool, pull out the extension plate in the extension frame. Multiple extension plates can form brackets of different lengths and be fixed by locking hinges. Since the end points of the extension plates are on both sides of the extension frame, the corrosion-resistant water pipes are driven to tilt, and the water pipe swinging groove in the mobile base adapts to its tilted state. In this way, different water layers at any position of the water pool can be sampled, thereby improving the scientificity and effectiveness of environmental management.

[0027] 3. Through the sampling mechanism set up, when sampling the surface layer, operate the wire drum to place the water suction cylinder and the waste water cylinder into the surface layer of the water through the hoist. When sampling the middle layer, continue to operate the wire drum to lower the submersible component. During the sampling process, the centrifugal pump provides suction to take samples from the water suction cylinder. At this time, the first rolling ball in the water suction cylinder is separated from the bottom of the water suction cylinder, allowing the sewage to enter the water suction cylinder and be transported to the empty sample storage tube through the filtration of the filter plate. During the flushing process, the flushing water flows through the pipeline to the water suction cylinder, squeezing the first rolling ball to seal the bottom of the water suction cylinder to prevent the cleaning water from causing secondary pollution to the sewage pool. The second rolling ball is squeezed to dredge the partition cylinder, allowing the cleaning water to flow into the waste water cylinder, thereby providing a sampling and flushing channel and carrier.

DETAILED DESCRIPTION

[0041] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0044] Specifically, sealing rings are provided at the bottom of the rotating outer frame 331 and the outside of the flow port 335, wherein the sealing ring at the bottom of the rotating outer frame 331 slides in the groove at the bottom of the sample storage box 31, and the sealing ring outside the flow port 335 slides in the groove on the side of the sample storage box 31. The output end of the rotating cylinder 32 penetrates the bottom of the sample storage box 31 and is engaged with the inner wall of the slot 336. The insertion slot 332 can be set to multiple numbers, so as to perform multiple groups of sampling. The opening of the first opener and closer 334 is a facing opening and is fixed inside the rotating outer frame 331.

[0045] Reference Figure 5 The sample storage assembly 34 includes a sample storage tube 341 slidably connected to the inner wall of the insertion groove 332, the outer wall of the sample storage tube 341 is fixedly connected to two symmetrically arranged limit blocks 342, the outer wall of the limit blocks 342 is slidably connected to the inner wall of the limit groove 333, the inner wall of the sample storage tube 341 is fixedly connected to a second opener 343, and the second opener 343 is sleeved on the outside of the first opener 334.

[0046] Specifically, a handle is provided on the top of the sample storage tube 341 for easy picking and placing, and the opening of the second opener and closeer 343 is also an opposite opening, so that the second opener and closeer 343 and the first opener and closeer 334 can be in two states of misalignment and alignment when they are put together.

[0047] Through the sample storage mechanism 3, three sample storage tubes 341 are installed for each sampling group, and samples are taken from the surface layer, middle layer and bottom layer of a point in the sewage pool respectively. The sample storage tubes 341 are installed in the rotating outer frame 331 in sequence, and clean water is stored in two of the sample storage tubes 341 for cleaning during the sampling process. The limiting blocks 342 on both sides of the sample storage tube 341 are aligned with the limiting grooves 333 in the insertion groove 332 and inserted, so that the second opener 343 falls on the first opener 334. At this time, the second opener 343 and the first opener 334 are in a misaligned state, and the flow port 335 and the inside of the sample storage tube 341 are not circulated. Then, the rotating cylinder 32 is operated, and the output end of the rotating cylinder 32 drives the rotating outer frame 331 to rotate in the sample storage box 31 through the card slot 336, and the empty sample storage tube 341 is facing the centrifugal water pump 41, and then the sample storage tube 341 is rotated in each insertion slot 332 to align the second opener 343 and the first opener 334. Thus, the interior of the sample storage tube 341 is connected to the extrusion tube 42 through the flow port 335, thereby providing a container for sampling and flushing, and converting through the rotating cylinder 32 to prevent the residual substances in the previous sample from contaminating the new sample, thereby achieving the effect of improving the sample purity and detection accuracy.

[0048] Reference Figure 3 - Figure 6 The pump pipe assembly 4 includes a centrifugal water pump 41 fixedly installed on the top of the support base 2, an outer wall of the centrifugal water pump 41 is fixedly connected with an extrusion pipe 42, one end of the extrusion pipe 42 away from the centrifugal water pump 41 is connected with the flow port 335 by penetrating the sample storage box 31, a suction pipe 43 is fixedly connected to the bottom of the centrifugal water pump 41, one end of the suction pipe 43 away from the centrifugal water pump 41 is fixedly connected with a corrosion-resistant water pipe 45 by penetrating the support base 2, an automatic hose reel 44 is fixedly installed between the support base 2 and the mobile base 1, and the corrosion-resistant water pipe 45 is wound around the inside of the automatic hose reel 44.

[0049] Specifically, the centrifugal water pump 41 has two rotation modes. When rotating forward, the suction pipe 43 sucks and the extrusion pipe 42 discharges. When rotating reversely, the two are switched. The length of the corrosion-resistant water pipe 45 is the distance between the maximum sampling point and the device. The corrosion-resistant water pipe 45 is automatically controlled by the automatic hose reel 44 to release and reel.

[0050] Through the provided pump pipe assembly 4, when sampling, the centrifugal water pump 41 is operated, and the centrifugal water pump 41 provides suction to take samples through the suction pipe 43 and the corrosion-resistant water pipe 45 by the sampling mechanism 6, and transports the samples to the empty sample storage tube 341. When flushing, the centrifugal water pump 41 is operated in reverse to draw clean water from the sample storage tube 341 to flush the pipeline and the pump, thereby providing power for sampling and flushing.

[0051] Reference Figure 6 - Figure 8The sampling mechanism 6 includes a wire drum 61 fixedly mounted on one end of the extension component 5, the output end of the wire drum 61 is fixedly connected to a hoist 62, the bottom of the hoist 62 is fixedly connected to a diving component 63, the diving component 63 includes a waste water cylinder 634 fixedly connected to the bottom of the hoist 62, the inner wall of the waste water cylinder 634 is fixedly connected to a water suction cylinder 631, one end of the corrosion-resistant water pipe 45 away from the centrifugal water pump 41 is fixedly connected to the inner wall of the water suction cylinder 631, a filter plate 632 is clamped on the inner wall of the water suction cylinder 631, a first rolling ball 633 is rollingly connected to the inner wall of the water suction cylinder 631, a partition cylinder 635 is fixedly connected to the inner wall of the waste water cylinder 634, the water suction cylinder 631 and the waste water cylinder 634 are connected via the partition cylinder 635, the inner wall of the partition cylinder 635 is rollingly connected to a second rolling ball 636, and a plurality of gravity blocks 637 are fixedly connected to the bottom of the waste water cylinder 634.

[0052] Specifically, the bottom of the hoist 62 is evenly distributed above the wastewater barrel 634, so that the wastewater barrel 634 can rise and fall more smoothly. The gravity provided by the gravity block 637 at the bottom of the wastewater barrel 634 is greater than the buoyancy of the wastewater barrel 634. When the wastewater barrel 634 is loaded with cleaned water, the gravity can be increased, so that the submersible component 63 can smoothly dive into the bottom layer of the sewage pool.

[0053] Through the sampling mechanism 6 that is set, when sampling the surface layer, the wire drum 61 is operated to place the water suction cylinder 631 and the waste water cylinder 634 into the surface layer of the water via the hoisting device 62. When sampling the middle layer, the wire drum 61 is continued to be operated to lower the submersible component 63. During the sampling process, the centrifugal pump 41 provides suction to sample from the water suction cylinder 631. At this time, the first rolling ball 633 in the water suction cylinder 631 is separated from the bottom of the water suction cylinder 631, allowing the sewage to enter the water suction cylinder 631 and be transported to the empty sample storage tube 341 through the filtration of the filter plate 632. During the flushing process, the flushing water flows through the pipeline to the water suction cylinder 631, squeezing the first rolling ball 633 to block the bottom of the water suction cylinder 631, thereby preventing the cleaning water flow from causing secondary pollution to the sewage pool. The second rolling ball 636 is squeezed to clear the partition cylinder 635, allowing the cleaning water to flow into the waste water cylinder 634, thereby providing a sampling and flushing channel and carrier.

[0054] During use, the device is moved to the side of the sewage pool by moving the base 1, and the universal wheels are locked. Three sample storage tubes 341 are set for each group of sampling, and samples are taken from the surface, middle and bottom layers of a point in the sewage pool respectively. The sample storage tubes 341 are installed in sequence in the rotating outer frame 331, and clean water is stored in two of the sample storage tubes 341 for cleaning during the sampling process. During installation, the limit blocks 342 on both sides of the sample storage tubes 341 are aligned with the limit grooves 333 in the insertion grooves 332 and inserted, so that the second opener 343 falls on the first opener 334. At this time, the second opener 343 and the first opener are aligned. 334 is in a dislocated state, and the flow port 335 and the inside of the sample storage tube 341 are not circulated. Then the rotating cylinder 32 is operated, and the output end of the rotating cylinder 32 drives the rotating outer frame 331 to rotate in the sample storage box 31 through the card slot 336, and the empty sample storage tube 341 is opposite to the centrifugal water pump 41, and then the sample storage tube 341 is rotated in each insertion slot 332, so that the second opener 343 and the first opener 334 are aligned, so that the inside of the sample storage tube 341 is connected to the extrusion tube 42 through the flow port 335, and the wire drum device 61 is operated to put the water suction cylinder 631 and the waste water cylinder 634 into the lifting device 62. At the surface of the water, the gravity block 637 at the bottom of the waste water cylinder 634 can effectively provide gravity, and then the centrifugal pump 41 is operated. The centrifugal pump 41 provides suction to take samples from the suction cylinder 631 through the suction pipe 43 and the corrosion-resistant water pipe 45. At this time, the first rolling ball 633 in the suction cylinder 631 is separated from the bottom of the suction cylinder 631, so that the sewage enters the suction cylinder 631 and is filtered by the filter plate 632 and transported to the empty sample storage tube 341. After the surface sampling is completed, the wire drum 61 is continued to be operated to lower the submersible component 63, and the automatic hose reel 44 releases the corrosion-resistant water pipe 45, and the operation is continued. The cylinder 32 is rotated to place one of the sample tubes 341 filled with clean water toward the centrifugal water pump 41. The centrifugal water pump 41 is then reversed to extract clean water from the sample tube 341 to flush the pipeline and the pump. The flushing water flows through the pipeline to the water suction cylinder 631, and the first rolling ball 633 is squeezed to block the bottom of the water suction cylinder 631 to prevent the cleaning water from causing secondary pollution to the sewage pool. The second rolling ball 636 is squeezed to clear the partition cylinder 635, so that the cleaning water flows into the waste water cylinder 634. After cleaning, the middle layer water sample is extracted; this process is repeated to extract the bottom layer water sample.

[0055] Example 2, reference Fig.10 - Fig.11 , which is the second embodiment of the present invention, and which is different from the first embodiment in that: Figure 5 The extension assembly 5 includes an extension frame 51 fixedly installed on the top of the support base 2, and the inner wall of the extension frame 51 is slidably connected with multiple extension plates 52. A locking hinge 53 is fixedly installed between two adjacent extension plates 52. The outer wall of the outermost extension plate 52 is hinged with a mounting frame 54 through the locking hinge 53, and the outer wall of the mounting frame 54 is hinged to the top of the wire reel 61.

[0056] Reference Fig.11 The inner wall of the movable base 1 is provided with a water pipe swing groove 46 , and the inner wall of the water pipe swing groove 46 is slidably connected to the outer wall of the corrosion-resistant water pipe 45 .

[0057] During use, when sampling is required at the middle point of the pool, an extension plate 52 is pulled out from the extension frame 51. Multiple extension plates 52 can form brackets of different lengths and are fixed by locking hinges 53. Since the end points of the extension plate 52 are located on both sides of the extension frame 51, the corrosion-resistant water pipe 45 is driven to tilt, and the water pipe swinging groove 46 in the mobile base 1 adapts to its tilting state, thereby sampling different water layers at any position of the pool, thereby achieving the effect of improving the scientificity and effectiveness of environmental management. The rest of the structure is the same as that of Example 1.

[0058] Working principle of the present invention:

[0059] During operation, the device is moved to the side of the sewage pool by moving the base 1, and the universal wheels are locked. Three sample storage tubes 341 are installed for each group of sampling. The surface, middle and bottom layers of a point in the sewage pool are sampled respectively. The sample storage tubes 341 are installed in the rotating outer frame 331 in sequence, and clean water is stored in two of the sample storage tubes 341 for cleaning during the sampling process.

[0060] During installation, the limit blocks 342 on both sides of the sample storage tube 341 are aligned with the limit grooves 333 in the insertion groove 332 and inserted, so that the second opener 343 falls on the first opener 334. At this time, the second opener 343 and the first opener 334 are in a misaligned state, and the flow port 335 and the inside of the sample storage tube 341 are not circulated. Then, the rotating cylinder 32 is operated, and the output end of the rotating cylinder 32 drives the rotating outer frame 331 to rotate in the sample storage box 31 through the card slot 336, and the empty sample storage tube 341 is facing the centrifugal water pump 41, and then the sample storage tube 341 is rotated in each insertion groove 332 to align the second opener 343 and the first opener 334, so that the inside of the sample storage tube 341 is connected with the extrusion tube 42 through the flow port 335.

[0061] The wire drum 61 is operated to place the water suction cylinder 631 and the waste water cylinder 634 into the water surface through the hoist 62. The gravity block 637 at the bottom of the waste water cylinder 634 can effectively provide gravity. The centrifugal water pump 41 is then operated to provide suction to take samples from the water suction cylinder 631 through the suction pipe 43 and the corrosion-resistant water pipe 45. At this time, the first rolling ball 633 in the water suction cylinder 631 is separated from the bottom of the water suction cylinder 631, allowing the sewage to enter the water suction cylinder 631 and be filtered by the filter plate 632 and transported to the empty sample storage tube 341.

[0062] After the surface sampling is completed, continue to operate the wire drum 61 to lower the submersible component 63, and the automatic hose reel 44 releases the corrosion-resistant water pipe 45, and operate the rotary cylinder 32 again, and one of the sample tubes 341 filled with clean water is facing the centrifugal water pump 41, and then the centrifugal water pump 41 is reversed to extract the clean water in the sample tube 341 to flush the pipeline and the pump. The flushing water flows through the pipeline to the water suction cylinder 631, and the first rolling ball 633 is squeezed to block the bottom of the water suction cylinder 631 to prevent the cleaning water from causing secondary pollution to the sewage pool. The second rolling ball 636 is squeezed to clear the partition cylinder 635, so that the cleaning water flows into the waste water cylinder 634. After cleaning is completed, the middle layer water sample is extracted; this process is repeated in sequence to extract the bottom layer water sample.

[0063] When sampling is required at the middle point of the water pool, an extension plate 52 is pulled out from the extension frame 51. Multiple extension plates 52 can form brackets of different lengths and are fixed by locking hinges 53. Since the end points of the extension plate 52 are located on both sides of the extension frame 51, the corrosion-resistant water pipe 45 is driven to tilt, and the water pipe swing groove 46 in the mobile base 1 adapts to its tilt state.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
