Description

Technical Field

[0001] The present invention relates to the technical field of water sample collection, and specifically to a water sample collection device for sewage treatment. Background Art

[0002] Sewage treatment is an important link in the field of environmental protection. With the rapid development of industrialization and urbanization, the sewage discharge is increasing continuously, and the water quality is becoming increasingly complex. In order to ensure the effectiveness of the sewage treatment process and the compliance of the effluent water quality, it is crucial to accurately understand the water quality characteristics of the sewage. As the first step to obtain the sewage treatment water quality information in the sewage tank, the accuracy and representativeness of the water sample collection in the sewage tank directly affect the subsequent water quality analysis and treatment process.

[0003] Traditional sampling methods mostly adopt manual sampling at regular intervals, which have problems such as low efficiency, inflexible time intervals, and being easily contaminated by humans. Although existing automatic sampling devices can achieve regular collection, such as the Chinese patent with the publication number CN221006924U discloses a water sample collection device for sewage treatment, there are still the following defects in the collection process:

[0004] 1. Currently, when collecting sewage in a sewage treatment tank, since the sewage collection samples at different positions and different depths are different, the collection of sewage water samples at a single position will result in incomplete water sample collection;

[0005] 2. After the sewage water sample is extracted at one position and then the sewage is extracted at another position, due to the residue of the previous sewage water sample extraction in the sampling pipeline, it will affect the accuracy of the subsequent sewage water sample collection;

[0006] 3. When the sampling pipeline moves at different depths, sewage surges into the sampling pipeline, causing internal pollution of the sampling pipeline and affecting the water sample collection accuracy;

[0007] 4. Since the collection is carried out through multi-position collection and the collected water samples are of multiple categories, the staff needs to repeatedly take and place the samples for collection, and the process is cumbersome. Summary of the Invention

[0008] Technical Problems to be Solved

[0045] In this invention, unless otherwise clearly specified and defined, the first feature being "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature may be that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature has a higher horizontal height than the second feature.

[0046] Refer to Figures 1 - 10, A water sample collection device for sewage treatment, including a mobile platform 6. There is a vehicle-mounted drive mechanism at the bottom of the mobile platform 6. The vehicle-mounted drive mechanism includes Mecanum wheels 9 installed at the four corners of the bottom of the mobile platform 6 through side brackets. On one side of the side bracket, a drive motor 8 for driving the rotation of the Mecanum wheel 9 is fixed by bolts. The structural principle and function of the Mecanum wheel 9 already belong to the prior art, so its structure is not specifically described. It can mainly achieve movements such as controlling forward, backward, lateral movement, and rotation. There are at least three sampling assemblies 3 at the extended part of the side of the mobile platform 6. Each sampling assembly 3 is installed on the mobile platform 6 through a transverse movement module 5 and a lifting module 4 and conducts precise detection and sampling of the three-dimensional space point coordinates in the sewage treatment tank. The transverse movement module 5 includes a transverse movement mounting frame 503 fixed to the top of the mobile platform 6 by bolts. On one side of the transverse movement mounting frame 503, a transverse movement electric push rod 501 is fixed by bolts. One end of the transverse movement electric push rod 501 passes through the transverse movement mounting frame 503 and is fixed by bolts to a transverse movement guide frame 502 that is slidably connected to the transverse movement mounting frame 503. The lifting module 4 includes a ball screw linear module 401 fixed to the end of the transverse movement guide frame 502 by bolts. There is a collection assembly 7 at the top of the mobile platform 6 for classifying and collecting the water samples collected by the sampling assemblies 3. On one side of each sampling assembly 3, there is a sealing system 2 for sealing the inside of the sampling assembly 3. There is a cleaning system 1 at the top of the mobile platform 6 for cleaning the inside of the sealed sampling assembly 3. Currently, when collecting sewage in the sewage treatment tank, since the collected samples of sewage at different positions and different depths are different, collecting the sewage water sample at a single position will result in incomplete water sample collection. Therefore, the vehicle-mounted drive mechanism is used to drive the mobile platform 6 to move, which can move along the square sewage treatment tank or move around the circular sewage treatment tank. Then, through the cooperation of the transverse movement module 5 and the lifting module 4, the sampling assembly 3 can classify and extract the sewage at different positions and different depths in the sewage tank. However, after the sewage water sample extraction at one position is completed, when extracting sewage at another position, due to the residue of the previous sewage water sample extraction in the sampling assembly 3, it will affect the accuracy of subsequent sewage water sample collection. Therefore, the sampling assembly 3 is cleaned by the cleaning system 1. During this cleaning process, the sealing system 2 is needed to seal the inside of the sampling assembly 3 to assist the cleaning system 1 in cleaning the sampling assembly 3, and the sealing system 2 can maintain the internal sealing state of the sampling assembly 3 when it moves at different depths, preventing sewage from pouring into the sampling assembly 3 during movement and causing internal pollution of the sampling assembly 3, which affects the water sample collection accuracy. After the collection is completed, the collected water needs to be classified and collected. Since the collection is carried out at multiple positions and the collected water samples are of multiple categories, the collection assembly 7 completes the classification collection of different groups, which is neat and convenient for subsequent staff to conduct classification detection and processing.

[0047] The sampling component 3 in the present invention includes a sampling water pump 306 fixed to the top of the moving platform 6 by bolts. One end of the water inlet of the sampling water pump 306 is fixed with a sampling water inlet pipe 304 by bolts. One end of the sampling water inlet pipe 304 is connected with a sampling water exploration pipe 301 through a sampling flexible hose 303. And the sampling water exploration pipe 301 is fixedly installed on one side of the sliding table of the lifting module 4 through a lifting seat 302. The bottom end of the sampling water exploration pipe 301 is welded with a sampling water exploration head 308. One end of the water outlet of the sampling water pump 306 is fixed with a sampling water outlet pipe 307 by bolts. Sampling solenoid valves 305 are provided in both the sampling water inlet pipe 304 and the sampling water outlet pipe 307. By controlling the opening or closing of the sampling solenoid valves 305 of the sampling component 3, and then by starting the sampling water pump 306, the sampling water pump 306 rotates to generate centrifugal force and enables the sampling water exploration pipe 301 to pump water through the sampling water exploration head 308. The pumped sewage enters the interior of the sampling water pump 306 through the sampling water inlet pipe 304 and is discharged and collected through the sampling water outlet pipe 307.

[0048] The closed system 2 in the present invention includes a closed cover 208 hinged to the outer wall of one side of the sampling water exploration head 308 through a spring hinge 207. A winding mounting frame 203 is fixed to one side of the lifting seat 302 by bolts. A winding roller 202 is rotatably connected to the interior of the winding mounting frame 203 through a bearing. A pulling rope 201 is wound around one side of the winding roller 202. A guiding seat 205 is welded to the outer wall of one side of the sampling water exploration head 308. An arc-shaped guiding ring groove 206 is opened on one side of the guiding seat 205. One end of the pulling rope 201 bypasses the arc-shaped guiding ring groove 206 and is fixed to the traction head provided on the closed cover 208. A winding motor 204 for driving the winding roller 202 to rotate along the axial direction is fixedly connected to one side of the lifting seat 302. By starting the winding motor 204, the winding motor 204 rotates to drive the winding roller 202 to rotate and perform a winding operation on the pulling rope 201. The pulling rope 201 is stressed and guided through the arc-shaped guiding ring groove 206 opened on the guiding seat 205 to apply a pulling force to the closed cover 208. At this time, the closed cover 208 opens, and the spring hinge 207 is stressed and generates a torsional force.

[0049] The cleaning system 1 in the present invention includes three groups of two-way water pumps 104 fixed to the top of the mobile platform 6 by bolts and corresponding to the sampling assembly 3.

A fresh water tank 107 and a surplus water collection tank 106 are fixed to the top of the mobile platform 6 by bolts. One end of the three groups of two-way water pumps 104 is connected to an electric three-way ball valve 105 through a branch pipe, and the other two water outlets of the electric three-way ball valve 105 are respectively connected to the fresh water tank 107 and the surplus water collection tank 106 through connecting water pipes.

After the sampling assembly 3 is closed by the closing system 2, the cleaning solenoid valve 102 is opened, and then the two-way water pump 104 and the sampling water pump 306 are started simultaneously. At this time, the two-way water pump 104 extracts fresh water from the inside of the fresh water tank 107 through the electric three-way ball valve 105, then enters the sampling assembly 3 through the cleaning flexible hose 103 and the cleaning water pipe 101, and then the sampling water pump 306 extracts the fresh water entering the sampling assembly 3, so as to realize the flow of fresh water inside the sampling assembly 3 and wash and clean the residues inside the sampling assembly 3. After the cleaning is completed, since there is still some flushing fresh water that has not been completely extracted inside the sampling assembly 3, the two-way water pump 104 is connected to the surplus water collection tank 106 through the electric three-way ball valve 105, and then the two-way water pump 104 pumps water from the sampling assembly 3, so that the unextracted flushing fresh water inside the sampling assembly 3 enters the surplus water collection tank 106 through the two-way water pump 104 and is collected, thereby emptying the inside of the sampling assembly 3.

A plurality of equally spaced insertion grooves are provided at the top of the high-precision turntable 704. A water sample collection tank 705 is inserted into the insertion groove. At the top of the heavy-duty turntable 702, there are three waste water collection tanks 703 corresponding to the high-precision turntable 704 for collecting the waste water for cleaning the sampling component 3. The top of the mobile platform 6 is fixedly bolted with a sealed mounting frame 1004. Two sealed guide rods 1002 are inserted into the top of the sealed mounting frame 1004. The bottom end of the sealed guide rod 1002 is fixedly bolted with a sealed lifting frame 1003. Three water sample collection pipes 706 are fixedly bolted to one side of the sealed lifting frame 1003. And the three water sample collection pipes 706 can be respectively inserted into the water sample collection tanks 705 arranged on the three high-precision turntables 704. The top ends of the three water sample collection pipes 706 are respectively communicated with one end of the three sampling water outlet pipes 307 through water sample collection flexible hoses 707. The top of the sealed mounting frame 1004 is fixedly bolted with a sealed electric push rod 1001 for driving the sealed lifting frame 1003 to move up and down. The top of the mobile platform 6 is provided with a sealing component 10 for sealing the water sample collection tank 705. The collected water samples discharged through the sampling water outlet pipes 307 enter the water sample collection tanks 705 respectively arranged on the three high-precision turntables 704 through the water sample collection flexible hoses 707 and the water sample collection pipes 706, and classified collection is realized. A reduction motor 701 for driving the heavy-duty turntable 702 to rotate along the axial direction is arranged inside the mobile platform 6. The bottom ends of the three high-precision turntables 704 all pass through the heavy-duty turntable 702 and are fixedly bolted with synchronous belt pulleys 712. And the three synchronous belt pulleys 712 are connected by a synchronous belt. The bottom end of one of the high-precision turntables 704 is fixedly bolted with a driven gear disc 709.

The rotation positioning component 11 includes two positioning pin holes 1104 opened on the circumferential outer side of the heavy-duty turntable 702 and a plurality of high-precision pin holes 1103 opened on the circumferential outer side of the three high-precision turntables 704 and corresponding to the water sample collection tank 705. The top of the mobile platform 6 is fixedly bolted with two waste water collection electromagnetic locks 1102 cooperating with the positioning pin holes 1104. The top of the heavy-duty turntable 702 is fixedly bolted with two water sample collection electromagnetic locks 1101 cooperating with the high-precision pin holes 1103 opened on the high-precision turntable 704. A plurality of water sample collection classification marks 708 corresponding to the plurality of water sample collection tanks 705 are provided at the top of the three high-precision pin holes 1103. Then, by starting the rotary motor 711,The rotation of the rotating electric machine 711 causes the driving gear 710 to drive the driven gear disk 709 to rotate. The rotation of the driven gear disk 709 drives the three high-precision turntables 704 to rotate through the synchronous belt and three synchronous belt pulleys 712 until the next water sample collection tank 705 on the high-precision turntable 704 rotates to the water sample collection position and stops. Then, the water sample collection electromagnetic lock 1101 is inserted into the high-precision pin hole 1103, and the high-precision turntable 704 is locked and fixed. When discharging waste water, the reduction motor 701 is started. The rotation of the reduction motor 701 drives the heavy-duty turntable 702 to rotate until the three waste water collection tanks 703 provided on the heavy-duty turntable 702 rotate to the lower part of the water sample collection pipe 706 and stop. Then, the waste water collection electromagnetic lock 1102 is inserted into the positioning pin hole 1104, and the position of the heavy-duty turntable 702 is fixed, so as to collect the cleaned waste water of the sampling assembly 3 through the waste water collection tank 703.,

[0051] The sealing assembly 10 in the present invention includes three frames 1008 fixed to the top of the moving platform 6 by bolts. Two transverse guide rails 1009 are fixed to the top of the frame 1008 by bolts. A transverse rack 1007 is slidably connected to the top of the transverse guide rail 1009 through a slide table. A transverse push frame 1010 is fixed between the two transverse racks 1007 by bolts. Three groups of vertical racks 1005 corresponding to the frame 1008 are fixed to the bottom of the sealing lifting frame 1003 by bolts. Two connecting gears 1006 are rotatably connected inside the frame 1008, and the connecting gears 1006 are respectively meshed with the transverse rack 1007 and the vertical rack 1005. Chutes 1012 are provided at the tops of multiple water sample collection tanks 705. A sealing cover 1011 for closing the top opening of the water sample collection tank 705 is slidably connected inside the chute 1012. Reset tension springs 1013 connected to the water sample collection tank 705 are provided on both sides of the sealing cover 1011. Since the high-precision turntable 704 and the heavy-duty turntable 702 rotate, the water samples collected in the water sample collection tank 705 will spill under the action of centrifugal force, and the water sample collection tank 705 is in an open state, which is likely to cause internal pollution of the water sample collection tank 705 and affect the subsequent test results. Therefore, the sealing cover 1011 is used to close the top opening of the water sample collection tank 705. Then, when collecting water samples, the sealing electric push rod 1001 is started. The sealing electric push rod 1001 extends to drive the sealing lifting frame 1003 and the vertical rack 1005 to move downward. Since the connecting gear 1006 is respectively meshed with the transverse rack 1007 and the vertical rack 1005, when the vertical rack 1005 moves downward, the transverse rack 1007 drives the transverse push frame 1010 to move horizontally through the connecting gear 1006, and the sealing cover 1011 at the top opening of the water sample collection tank 705 is squeezed, so that the sealing cover 1011 moves along the chute 1012, thereby opening the water sample collection tank 705, and then facilitating the collection of the water samples drawn by the upper water sample collection pipe 706. After the collection is completed, the sealing electric push rod 1001 can be shortened to reset, then the transverse push frame 1010 moves horizontally to reset, and the sealing cover 1011 moves reversely along the chute 1012 under the action of the reset tension spring 1013 to complete the collection of the water samples.

[0052] When the present invention is in use, it is divided into the following steps:

[0053] S1: First, the vehicle-mounted drive mechanism is used to drive the moving platform 6 to move, which can move along the square sewage treatment tank or move around the circular sewage treatment tank. Then, through the cooperation of the transverse movement module 5 and the lifting module 4, the sampling assembly 3 can extract sewage at different positions and different depths in the sewage tank in a classified manner;

[0054] S2: Then start the sealing electric push rod 1001. The elongation of the sealing electric push rod 1001 drives the sealing lifting frame 1003 and the vertical rack 1005 to move downward. Since the connecting gear 1006 meshes with the horizontal rack 1007 and the vertical rack 1005 respectively, when the vertical rack 1005 moves downward, the horizontal rack 1007 is driven by the connecting gear 1006 to drive the horizontal push frame 1010 to move horizontally, and the sealing cover 1011 at the top opening of the water sample collection tank 705 is squeezed, so that the sealing cover 1011 moves along the chute 1012, thereby opening the water sample collection tank 705, and then facilitating the collection of the water sample extracted by the upper water sample collection pipe 706;

[0055] S3: Then start the winding motor 204. The rotation of the winding motor 204 drives the winding roller 202 to rotate and wind the pulling rope 201. The pulling rope 201 is stressed and guided through the arc-shaped guiding ring groove 206 opened in the guiding seat 205 to apply a pulling force to the closing cover 208. At this time, the closing cover 208 opens, and the spring hinge 207 is stressed and generates a torsional force. Then, the sampling solenoid valve 305 is controlled to open the sampling assembly 3. Then, by starting the sampling water pump 306, the sampling water pump 306 rotates to generate a centrifugal force, and the sampling water probe 301 pumps water through the sampling water probe head 308. The extracted sewage enters the sampling water pump 306 through the sampling inlet pipe 304 and is discharged through the sampling outlet pipe 307. The collected water sample discharged through the sampling outlet pipe 307 enters the water sample collection tanks 705 respectively arranged on the three high-precision turntables 704 through the water sample collection telescopic hose 707 and the water sample collection pipe 706, and realizes classified collection;

[0056] S4: After the collection is completed, the sealing electric push rod 1001 can be shortened and reset, then the horizontal push frame 1010 moves horizontally and resets, and the sealing cover 1011 moves reversely along the chute 1012 and resets under the action of the reset tension spring 1013;

[0057] S5: Then, when sampling at the next position through the cooperation of the vehicle-mounted driving mechanism, the transverse movement module 5 and the lifting module 4, start the reduction motor 701. The rotation of the reduction motor 701 drives the heavy-duty turntable 702 to rotate until the three wastewater collection boxes 703 arranged on the heavy-duty turntable 702 rotate to the lower part of the water sample collection pipe 706 and stop. Then, the wastewater collection electromagnetic lock 1102 is inserted into the positioning pin hole 1104 to fix the position of the heavy-duty turntable 702;

[0058] S6: Then, after the sampling assembly 3 is enclosed by the closed system 2, open the cleaning solenoid valve 102, and then start the two-way water pump 104 and the sampling water pump 306 simultaneously. At this time, the two-way water pump 104 extracts clear water from the inside of the clear water tank 107 through the electric three-way ball valve 105, and then enters the sampling assembly 3 through the cleaning telescopic hose 103 and the cleaning water pipe 101. Then, the sampling water pump 306 extracts the clear water that enters the sampling assembly 3, so as to realize the flow of clear water inside the sampling assembly 3, wash and clean the residues inside the sampling assembly 3, and collect the cleaning wastewater of the sampling assembly 3 through the wastewater collection tank 703;

[0059] S7: After the cleaning is completed, connect the two-way water pump 104 to the surplus water collection tank 106 through the electric three-way ball valve 105, and then the two-way water pump 104 pumps water from the inside of the sampling assembly 3, so that the uncompletely extracted flushing clear water existing inside the sampling assembly 3 enters the surplus water collection tank 106 through the two-way water pump 104 and is collected, thereby emptying the inside of the sampling assembly 3;

[0060] S8: Then release the wastewater collection electromagnetic lock 1102, and then start the reduction motor 701. The rotation of the reduction motor 701 drives the heavy-duty turntable 702 to rotate and reset, and is fixed by the wastewater collection electromagnetic lock 1102. At this time, by starting the rotation motor 711, the rotation of the rotation motor 711 causes the driving gear 710 to drive the driven gear disk 709 to rotate. The rotation of the driven gear disk 709 drives the three high-precision turntables 704 to rotate through the synchronous belt and the three synchronous belt pulleys 712 until the next water sample collection tank 705 on the high-precision turntable 704 rotates to the water sample collection position and stops. Then, the water sample collection electromagnetic lock 1101 is inserted into the high-precision pin hole 1103, and the high-precision turntable 704 is locked and fixed, thus completing the preparatory work for the next round of water sample collection.
