Description

Technical Field

[0001] The present invention relates to the technical field of sewage sampling, and in particular to a sewage treatment sample detection assistant based on water body mapping services. Background Art

[0002] With the acceleration of urbanization and the development of industrialization, water shortage and water pollution are becoming increasingly serious. Wastewater treatment has become a key measure to protect water resources and improve the quality of the water environment. However, wastewater treatment faces many challenges, such as complex pollution sources, difficult treatment, and limited monitoring methods. Therefore, it is necessary to use advanced technical means to improve the efficiency and accuracy of wastewater treatment. When evaluating water resources, the resource evaluation system will consider factors such as the quantity, quality, distribution, and development and utilization status of water resources. This information is crucial for formulating wastewater treatment strategies, because wastewater treatment needs to be planned and implemented based on the actual situation of water resources. Water body mapping services use advanced mapping technology and equipment to accurately measure and record water bodies, providing a scientific basis for wastewater treatment. Through water body mapping, the location, scope, and discharge of pollution sources can be accurately determined, providing a basis for formulating targeted treatment measures. Water body mapping services can provide high-precision water quality data, including key indicators such as dissolved oxygen content and ammonia nitrogen concentration. These data are of great significance for evaluating water quality and formulating water resource protection strategies.

[0003] In the process of sewage treatment, sampling water quality is a crucial step. By analyzing water samples, we can understand the types, concentrations and distribution of pollutants, thus providing an important basis for formulating scientific and reasonable treatment plans. When in use, the existing sewage sampling device still has the following defects:

[0004] The existing sewage sampling device is to tie a rope to a sampling bucket. When sampling, the sampling bucket is placed in the sewage to be sampled, and the rope is loosened so that the sampling bucket can reach a specified depth. The valve of the sampling bucket is opened by the pressure of water, and the sewage enters the sampling bucket from one end of the valve. Then the rope is lifted, the water pressure is reduced, and the valve is closed, so that the water in the sampling bucket will not flow out from the other end of the valve again, and the sampling is completed. After the sampling is completed, the valve is opened to discharge the sampled water for testing. Not only does the operator need to loosen the valve, but also the sampled water is discharged from the sampling bucket. , air enters the sampling barrel from one end of the valve, and the sampled water is discharged from the sampling barrel under the combined effect of air pressure and water gravity. The operation is not convenient enough, and it takes a long time to complete the collection of sampled water, which reduces the efficiency of sewage sampling. In addition, since sewage enters the sampling barrel from one end of the valve, the air in the sampling barrel is discharged from the sampling barrel from the other end of the valve, so that sewage can only enter the sampling barrel slowly. After a certain period of waiting, the operator is prone to misjudgment and lifts the sampling barrel when the water in the sampling barrel is not full, resulting in sampling failure, further reducing the efficiency of sampling. Summary of the invention

[0005] In view of the fact that the existing technology has the problem of collecting the sampled water after sampling, the operation is cumbersome, and water and air enter and exit from the same outlet, the water cannot be collected quickly, and when sampling sewage, the water can only be sampled slowly, which may easily cause misjudgment by the operator, resulting in the sampling bucket being lifted up before the water in the sampling bucket is full, resulting in sampling failure. A sewage treatment sample detection assistant based on water body mapping service is proposed.

[0006] The present application provides a sewage treatment sample detection assistant based on water body mapping services, the purpose of which is: when collecting samples, the sampling bucket is inverted to collect water, so that the sample collection is faster, and when sampling, the sewage can enter the sampling bucket faster, reducing the probability of misjudgment by the operator, so that the sampling bucket is full of sample water when it is lifted.

[0022] 1. By loosening or reeling in the pull rope, the sampling bucket is placed in the water or lifted from the water.

[0024] 3. By triggering the assembly, the limit plate rotates in the through hole, driving the fixed shaft to rotate, causing the torsion spring to twist and deform, causing the limit plate to rotate out of the through hole, thereby limiting the first float, so that when the water in the sampling bucket is poured out, the first float will not block the top sampling port, so that the water in the sampling bucket can be drained.

[0039] 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.

[0040] Example 1, reference Figure 1-Figure 12 , which is the first embodiment of the present invention, provides a sewage treatment sample detection assistant based on water body mapping service, including a sampling barrel 1, a counterweight block 11 fixedly connected to the bottom of the sampling barrel 1, a top sampling port 12 opened at the top of the sampling barrel 1, a bottom sampling port 13 opened at the bottom of the sampling barrel 1, a plurality of fixed ropes 14 distributed in a circular array fixedly connected to the sampling barrel 1, and a pull rope 15 fixedly connected to the top of the fixed rope 14, and also includes a sampling unit installed on the sampling barrel 1; the sampling unit includes a sampling component installed on the sampling barrel 1, a clamping component installed in the sampling barrel 1, and a pull rope 15 installed on the sampling component. The push-open component and the sampling component include a buoyancy component 2 installed in the sampling barrel 1, a rotating sealing component 3 installed at the bottom of the buoyancy component 2, and a transverse sealing component 4 installed at the top of the buoyancy component 2; the sampling component is used to open and close the top sampling port 12 and the bottom sampling port 13, the clamping component is used to clamp the bottom sampling port 13, and the push-open component is used to open the top sampling port 12; the buoyancy component 2 includes an L-shaped plate 21 fixedly connected to the bottom of the sampling barrel 1, a column 22 fixedly connected to one side of the L-shaped plate 21, a first float 23 limitedly slidably connected to the outside of the column 22, and the first float 23 is slidably connected to the L-shaped plate 21.

[0041] Specifically, by loosening or winding the pull rope 15, the sampling bucket 1 is placed in the water or lifted from the water, and the sampling bucket 1 can be vertically raised or lowered through multiple fixed ropes 14 distributed in a circular array, so that the water sample obtained is more accurate, and the counterweight block 11 can overcome the buoyancy of the water and move downward to enter the specified depth for sampling, and through the top sampling port 12 and the bottom sampling port 13, the top and bottom of the sampling bucket 1 are both open during sampling, so that the sampling bucket 1 is connected from top to bottom, so that sewage can enter the sampling bucket 1 very quickly without waiting for a long time, thereby improving the sampling efficiency and the sampling accuracy. When the sampling bucket 1 is lifted, the top sampling port 12 and the bottom sampling port 13 are closed by the sampling component, so that sewage no longer enters the sampling bucket 1, and sampling The water in the barrel 1 will not flow out. After sampling is completed, the sampling barrel 1 is inverted, and the top sampling port 12 is pushed open by pushing the component so that the sample water can flow out. During the outflow of the sample water, the bottom sampling port 13 will be opened immediately. At this time, the sampling barrel 1 is connected from top to bottom, so that the water in the sampling barrel 1 can be quickly discharged and collected, which not only simplifies the operation steps but also improves the water collection efficiency. The column 22 is fixedly installed at the bottom of the sampling barrel 1 through the L-shaped plate 21. When water enters the sampling barrel 1, the first float 23 is affected by the buoyancy and slides upward on the column 22 to open the bottom sampling port 13. When the first float 23 moves to the top of the sampling barrel 1, the top sampling port 12 is sealed. At the same time, the bottom sampling port 13 is closed, so that the sampling barrel 1 forms a sealed structure again.

[0042] Reference Figure 5 The rotary sealing assembly 3 includes two connecting shafts 31 rotatably connected to the inner side of the bottom sampling port 13 and symmetrically distributed, a rotary sealing plate 32 fixedly connected between the two connecting shafts 31, gears 33 fixedly connected to the outer sides of the two connecting shafts 31, two racks 34 slidably connected to the sampling barrel 1 and symmetrically distributed in the center, the two racks 34 are respectively meshed with the two gears 33, a first vertical rod 35 and a second vertical rod 36 fixedly connected to the tops of the two racks 34, a first cross bar 37 and a second cross bar 38 fixedly connected to both sides of the first float 23, the first vertical rod 35 and the second vertical rod 36 are respectively slidably connected to the first cross bar 37 and the second cross bar 38, and a floating plate 39 fixedly connected to the top of the second vertical rod 36.

[0043] Specifically, when the first float 23 slides upward on the column 22, the first cross bar 37 and the second cross bar 38 slide outside the first vertical bar 35 and the second vertical bar 36. Since the first vertical bar 35 is shorter than the second vertical bar 36, when the first cross bar 37 slides to the top of the first vertical bar 35, the second cross bar 38 slides to the bottom of the second vertical bar 36. The first cross bar 37 will drive the first vertical bar 35 to move upward, and the second cross bar 38 will continue to slide on the second vertical bar 36, thereby driving the rack 34 at the bottom of the first vertical bar 35 to move upward, so that the gear 33 meshing with it rotates, driving the connecting shaft 31 to rotate, and driving the rotating sealing plate 32 to rotate. The bottom sampling port 13 is opened so that sewage can enter the sampling barrel 1 from the bottom sampling port 13. Water continuously enters the sampling barrel 1, causing the first float 23 to continuously slide upward on the column 22. When the second cross bar 38 moves to the top of the second vertical bar 36, it will drive the second vertical bar 36 to move upward, driving the bottom rack 34 to move upward. Since the two racks 34 are centrally symmetrically distributed, they will drive the gear 33 meshing with them to rotate, driving the connecting shaft 31 to rotate in the opposite direction to the previously rotated connecting shaft 31, and driving the rotating sealing plate 32 to rotate in the opposite direction, closing the bottom sampling port 13, so that the water in the sampling barrel 1 no longer flows out.

[0044] Reference Figure 6 The transverse sealing assembly 4 includes a movable groove 41 opened at the top of the sampling barrel 1, a transverse sealing plate 42 slidably connected to the top sampling port 12, the transverse sealing plate 42 is sealingly and slidably connected to the movable groove 41, a circular groove opened in the movable groove 41, a first spring 43 fixedly connected between the transverse sealing plate 42 and the inner wall of the circular groove, two symmetrically distributed extrusion blocks 44 fixedly connected to the movable groove 41, a first connecting rope 45 fixedly connected to the transverse sealing plate 42, the first connecting rope 45 is slidably connected to the two extrusion blocks 44, a rubber ball 46 fixedly connected to the first connecting rope 45, a first inclined surface 47 opened on the extrusion block 44, a second floating ball 48 slidably connected to the top of the sampling barrel 1, and the end of the first connecting rope 45 away from the transverse sealing plate 42 passes through the sampling barrel 1 and is fixedly connected to the second floating ball 48.

[0045] Specifically, the sampling barrel 1 continues to sink in the sewage, and the buoyancy of the second float 48 continues to increase. The second float 48 continuously pulls the first connecting rope 45, and then pulls the rubber ball 46. Since the rubber ball 46 is located on one side of the two extrusion blocks 44, the rubber ball 46 is not easily pulled under the action of the two extrusion blocks 44. When the buoyancy of the second float 48 is greater than the resistance of the two extrusion blocks 44 to the rubber ball 46, the rubber ball 46 can pass between the two extrusion blocks 44, and pull the transverse sealing plate 42, so that the first spring 43 is stretched, and the elastic force of the first spring 43 is less than the buoyancy of the second float 48, so the first spring 43 is easily stretched, so that the transverse sealing plate 42 moves To the side of the movable groove 41, the top sampling port 12 is fully opened. At this time, the sampling bucket 1 sinks to a specified depth, so that the water at the specified depth can be sampled. After the sampling is completed, the sampling bucket 1 is pulled upward, and the buoyancy of the second float 48 gradually decreases. The first spring 43 will reset, causing the transverse sealing plate 42 to slide toward the side of the top sampling port 12, and the rubber ball 46 is driven to move through the first connecting rope 45. Under the action of the first inclined surface 47, the rubber ball 46 slides over the two extrusion blocks 44, that is, the extrusion blocks 44 will not block the rubber ball 46 again, making it difficult to reset the transverse sealing plate 42. By resetting the transverse sealing plate 42, the top sampling port 12 is sealed, so that the external sewage no longer enters the sampling bucket 1.

[0046] Example 2, reference Figure 7-Figure 9 , is the second embodiment of the present invention, which is different from the first embodiment in that: the clamping component includes a pushing component 5 installed at the top of the sampling barrel 1, and a clamping component 6 installed at the bottom of the sampling barrel 1; the pushing component 5 includes a fixed box 51 fixedly connected to the top of the sampling barrel 1, a pushing rod 52 slidably connected to the bottom of the fixed box 51, a moving rod 53 limitedly slidably connected to one side of the fixed box 51, an inclined surface provided at one end of the moving rod 53, the pushing rod 52 is limitedly slidably connected to the inclined surface, two symmetrically distributed guide grooves provided on the moving rod 53, two symmetrically distributed guide blocks fixedly connected to the fixed box 51, a second spring 54 fixedly connected between the guide block and the inner wall of the guide groove, a second connecting rope 55 fixedly connected to the other end of the moving rod 53, a roller 56 fixedly installed on the inner wall of the sampling barrel 1, and the second connecting rope 55 passes around the roller 56.

[0047] Specifically, by pushing the assembly 5, the clamping assembly 6 clamps and limits the rotating sealing plate 32. When the first float 23 moves to the top of the sampling barrel 1, the pushing rod 52 is squeezed to move upward, so that the pushing rod 52 slides on the inclined surface, and the moving rod 53 moves to the outside of the fixed box 51, so that the guide block slides on the inside of the guide groove, and the second spring 54 is squeezed to move the second connecting rope 55 downward. Under the action of the roller 56, the second connecting rope 55 moves along a certain trajectory, so that the clamping assembly 6 limits the rotating sealing plate 32. Then, when the sampling barrel 1 is lifted, the bottom sampling port 13 will not be opened, so that the sampling barrel 1 is always in a sealed state.

[0048] Reference Fig. 9 The clamping assembly 6 includes a slide groove opened at the bottom of the sampling barrel 1, a slider 61 slidably connected to the slide groove, a second connecting rope 55 fixedly connected to the slider 61, an insertion rod 62 fixedly connected to the slider 61, a slot 63 opened on the rotating sealing plate 32, the insertion rod 62 is inserted into the slot 63, and a third spring 64 fixedly connected between the slider 61 and the inner wall of the slide groove.

[0049] Specifically, when the second connecting rope 55 moves downward, since the third spring 64 is in a compressed state, the third spring 64 will be reset, so that the slider 61 moves toward the rotating sealing plate 32 on the inner side of the slide groove, driving the insertion rod 62 to move, so that the insertion rod 62 is plugged into the inner side of the slot 63, and the rotating sealing plate 32 is limited. The rest of the structure is the same as that of the first embodiment.

[0050] Example 3, reference Figure 10-12 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the pushing component includes a pushing component 7 installed on the buoyancy component 2, a limiting component 8 installed on the buoyancy component 2, and a trigger component 9 installed on the pushing component 7; the pushing component 7 includes an active cavity 71 opened at the top of the column 22, a fixed block 72 slidingly connected in the active cavity 71, a pushing rod 73 fixedly connected to the top of the fixed block 72, the pushing rod 73 is connected through the top of the active cavity 71, a first wedge block 74 fixedly connected to the top of the pushing rod 73, a second inclined surface 75 opened on the transverse sealing plate 42, and the first wedge block 74 and the second inclined surface 75 are slidingly connected.

[0051] Specifically, when the sampling barrel 1 is full of samples, the sampling barrel 1 is inverted. Under the action of gravity, the fixed block 72 slides downward in the movable cavity 71, driving the push rod 73 to move downward, driving the first wedge block 74 to move downward, so that the first wedge block 74 slides on the second inclined surface 75. Under the action of the second inclined surface 75, the transverse sealing plate 42 is pushed into the movable groove 41, so that the top sampling port 12 is opened, so that the sample in the sampling barrel 1 can flow out. Since the sampling barrel 1 is inverted, under the action of the buoyancy of water, the first float 23 moves upward on the column 22, so that the first float 23 no longer squeezes the push rod 52, and the second spring 5 4 will be reset, so that the moving rod 53 moves into the fixed box 51, the second connecting rope 55 is pulled, so that the second connecting rope 55 moves upward, and the slider 61 is pulled, so that the third spring 64 is squeezed, so that the insertion rod 62 is separated from the inner side of the slot 63, and the rotating sealing plate 32 will no longer be limited. Under the buoyancy of water, the floating plate 39 will move upward, drive the second vertical rod 36 to move upward, drive the rack 34 to move upward, drive the gear 33 to rotate, drive the connecting shaft 31 to rotate, drive the rotating sealing plate 32 to rotate, so that the bottom sampling port 13 is opened, so that the sampling barrel 1 is connected from top to bottom, so that the sample in the sampling barrel 1 can be poured out more easily.

[0052] Reference Fig.11 The limiting assembly 8 includes a through hole 81 arranged on the column 22 and connected to the active cavity 71, two fixed shafts symmetrically distributed in the through hole 81, a limiting plate 82 arranged between the two fixed shafts, and a torsion spring arranged between the limiting plate 82 and the through hole 81, and the torsion spring is sleeved on the fixed shaft.

[0053] Specifically, by triggering the component 9, the limit plate 82 rotates in the through hole 81, driving the fixed shaft to rotate, causing the torsion spring to twist and deform, so that the limit plate 82 rotates out of the through hole 81, and then limits the first float 23, so that when the water block in the sampling bucket 1 is poured out, the first float 23 will not block the top sampling port 12, so that the water in the sampling bucket 1 can be drained.

[0054] Reference Fig.12 The trigger assembly 9 includes a slot 91 formed on the fixed block 72 , a trigger block 92 slidingly connected in the slot 91 , a third inclined surface formed on the trigger block 92 , and a trigger spring 93 fixedly connected between the inner wall of the slot 91 and the trigger block 92 .

[0055] Specifically, when the sampling barrel 1 is inverted, the fixed block 72 will move downward in the active cavity 71. At the beginning, the trigger block 92 is located in the empty slot 91 under the action of the active cavity 71, compressing the trigger spring 93. When the trigger block 92 moves to the through hole 81, the trigger spring 93 will be reset without being forced, so that the trigger block 92 moves to the outside of the empty slot 91 and pushes the limit plate 82. When the sampling barrel 1 resumes its upright state, the fixed block 72 moves in the opposite direction in the active cavity 71. Under the action of the third inclined surface and the active cavity 71, the trigger block 92 re-enters the empty slot 91, and the torsion spring will return to its original state, so that the limit plate 82 rotates into the through hole 81.

[0056] Reference Figure 2 and Figure 3 , and also includes a sealing sleeve 10 arranged on the top of the sampling barrel 1, and the sealing sleeve 10 is a truncated cone structure.

[0057] Specifically, when the first float 23 moves upward in the sampling barrel 1, the top of the first float 23 will contact the sealing sleeve 10, and the top sampling port 12 will be sealed under the joint action of the sealing sleeve 10 and the first float 23, and the sealing sleeve 10 is a truncated cone structure, so that the first float 23 can more easily seal the sealing sleeve 10. The rest of the structure is the same as that of Example 2.

[0058] In summary, the working principle of the present invention is as follows: when in use, under the action of the pull rope 15, the sampling bucket 1 is placed in the sewage, and the sampling bucket 1 is always vertically downward when sampling through the fixed rope 14. The second float 48 is acted upon by the buoyancy to pull the first connecting rope 45, squeeze the first spring 43, and pull the transverse sealing plate 42 to move into the movable groove 41, so that the top sampling port 12 is opened, allowing the sewage to enter the sampling bucket 1. The first float 23 is acted upon by the buoyancy to move upward on the column 22, driving the first cross bar 37 to move upward, driving the first vertical bar 37 to move upward, and driving the first vertical bar 37 to move upward. The rod 35 moves upward, driving the rack 34 to move upward, driving the gear 33 to rotate, driving the connecting shaft 31 to rotate, driving the rotating sealing plate 32 to rotate, and opening the bottom sampling port 13 again, so that the sampling bucket 1 is connected from top to bottom, allowing sewage to quickly enter the sampling bucket 1; when the first float 23 moves to the bottom of the sealing sleeve 10, the top sampling port 12 is sealed, and the floating plate 39 is affected by the buoyancy of the water, which will drive the second vertical rod 36 to move upward, and under the cooperation of the rack 34 and the gear 33, the rotating sealing plate 32 is rotated again, and the rotation direction is opposite to the previous one, and the bottom sampling port 13 is also closed.

[0059] The first float 23 squeezes the push rod 52, so that the moving rod 53 moves toward the outside of the fixed box 51, and squeezes the second spring 54, so that the second connecting rope 55 moves downward. Under the action of the third spring 64, the slider 61 moves on the inner side of the slide groove toward the side of the rotating sealing plate 32, driving the insertion rod 62 to move into the slot 63, limiting the rotating sealing plate 32, so that the rotating sealing plate 32 cannot rotate, and the bottom sampling port 13 cannot be opened. The pull rope 15 is pulled, the buoyancy of the water changes, and the buoyancy of the second float 48 is reduced. The first spring 43 will be reset, so that the transverse sealing plate 42 moves toward the top sampling port 12 to seal the top sampling port 12, and the pull rope 15 is lifted to move the sampling bucket 1 out of the water to complete the sampling.

[0060] When collecting samples, the sampling barrel 1 is turned upside down, and the first float 23 moves upward due to the buoyancy, no longer squeezing the push rod 52, and no longer sealing the sealing sleeve 10. The second spring 54 is reset, so that the moving rod 53 moves into the fixed box 51, and the second connecting rope 55 is pulled, so that the slider 61 moves away from the rotating sealing plate 32 on the inner side of the slide groove, so that the insertion rod 62 moves out from the inner side of the slot 63, and no longer limits the rotating sealing plate 32. The fixed block 72 slides in the active cavity 71, driving The push rod 73 and the first wedge block 74 move, and under the action of the second inclined surface 75, the transverse sealing plate 42 is pushed open, so that the top sampling port 12 is opened, so that the water in the sampling barrel 1 can be discharged, and the floating plate 39 is subjected to the buoyancy, driving the second vertical rod 36 to move upward, and under the action of the rack 34 and the gear 33, the rotating sealing plate 32 is driven to rotate, so that the bottom sampling port 13 is also opened, so that the sampling barrel 1 is connected from top to bottom again, so that the water in the sampling barrel 1 can be quickly discharged.
