[0033] The following will be combined with the attached Figures 1 to 11The technical solution of the present invention is described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] The present invention provides a wastewater quality detection device through improvement. Figure 1-Figure 11 As shown, the mounting frame 1 includes a first vertical frame 39 and a second vertical frame 40 on both sides, and a horizontal frame 41 is arranged on the top of the first vertical frame 39 and the second vertical frame 40; a lower swing seat 3 is fixedly arranged on the inner side of the first vertical frame 39, and an upper hanging plate 4 is fixedly arranged on the bottom of the horizontal frame 41; a swing shaft 5 is rotatably arranged in the middle of the first vertical frame 39, a swing fan 6 is fixedly arranged on the inner side of the swing shaft 5, and a meshing frame 7 facing downward is arranged in the middle of the swing shaft 5; a swing tube 10 is movably arranged between the lower swing seat 3 and the second vertical frame 40, a swing gear 11 meshing with the swing fan 6 is arranged on one side of the swing tube 10, and symmetrical loading plates 12 are arranged on both sides of the swing tube 10; A rotating shaft 22 is rotatably arranged above a vertical frame 39, an outer gear ring 23 is fixedly arranged on the inner side of the rotating shaft 22, and an inner gear 24 is fixedly arranged in the middle of the outer gear ring 23; a flip shaft 27 is movably installed on the upper hanging plate 4, a flip gear 28 intermittently meshing with the outer gear ring 23 and the inner gear 24 is installed on the inner side of the flip shaft 27, and a flip cylinder 30 is fixedly arranged on the outer side of the flip shaft 27; a collecting pipe 14 is also fixedly arranged on the second vertical frame 40, and when the loading plate 12 swings back and forth, the wastewater flows back into the flip cylinder 30 along the swinging pipe 10 and the collecting pipe 14, and under the intermittent drive of the outer gear ring 23 and the inner gear 24, the flip cylinder 30 flips to vibrate and stir the wastewater.

[0035] In this embodiment: the wastewater quality detection device is mainly divided into three parts: a loading plate 12, a turning cylinder 30 and a sampling frame 32. When the device is in use, the mounting frame 1 is first fixed to the top of the wastewater pool 2, and then the control panel 38 and the motor 8 are started. When the motor 8 is started, the swing fan 6 drives the swing tube 10 and the loading plate 12 to swing back and forth. At the same time, driven by the belt 29, the outer gear ring 23 and the inner gear 24 also drive the turning cylinder 30 to rotate intermittently. When the loading plate 12 on the left side swings from the bottom to the top, the wastewater flows to the middle through the loading plate 12. When the loading plate 12 on the left side swings upward from the horizontal position, the outer water inlet trough 13 on the left side overlaps with the inner water inlet trough 17 on the left side, and the wastewater on the loading plate 12 on the left side enters the swing tube 10. At this time, under the action of the water pump 21, the wastewater enters the turning cylinder 30 through the collecting pipe 14. When the left side of the loading plate 12 swings from the bottom to the top, the inner tooth portion 26 on the inner gear 24 meshes with the flip gear 28, and the flip cylinder 30 drives the wastewater to rotate clockwise. When the left loading plate 12 swings downward from the horizontal position, the outer water inlet trough 13 on the left does not overlap with the inner water inlet trough 17 on the left, and the wastewater in the swing tube 10 will not flow back to the left loading plate 12. At this time, the outer water inlet trough 13 on the right partially overlaps with the inner water inlet trough 17 on the right, and the wastewater on the right loading plate 12 flows into the swing tube 10. When the left side of the loading plate 12 swings from the top to the bottom, the outer tooth portion 25 on the outer gear ring 23 meshes with the flip gear 28, and the flip cylinder 30 drives the wastewater to rotate counterclockwise. In the gap of reversing, the cylinder 18 is started to make the cap 19 disengage from the flip cylinder 30, and the wastewater in the flip cylinder 30 falls into the collection part 33 below. After the wastewater flows out, the cylinder 18 is started again to make the cap 19 seal the side of the turning cylinder 30. At this time, the stirred wastewater will fall into the collecting part 33 below, and then the corresponding control valve 35 is opened, and the wastewater is stored in the sampling tube 36 while the sensor 37 detects the wastewater. When all the sampling tubes 36 store the wastewater samples, the detection operation is completed.

[0036] See attached Figure 1 -Attached Figure 3 A motor 8 is also installed on the outside of the first vertical frame 39. The output end of the motor 8 passes through the first vertical frame 39. The end of the output end of the motor 8 is provided with a swing arm 9 that cooperates with the engagement frame 7. The output end of the motor 8 is connected to the rotating shaft 22 through a belt 29.

[0037] In this embodiment, when the motor 8 is started, the swing arm 9 and the meshing frame 7 cooperate to drive the swing fan 6 to swing back and forth, thereby driving the swing tube 10 and the loading plate 12 to swing back and forth. At the same time, driven by the belt 29, the motor 8 also drives the outer gear ring 23 and the inner gear 24 to rotate.

[0038] See attached Figure 1The mounting frame 1 is fixedly installed above the wastewater tank 2.

[0039] In this embodiment, the device is arranged above the wastewater pool 2, and the design of the loading plate 12 can automatically sample and test the wastewater multiple times.

[0040] See attached Figure 4 -Attached Figure 6 and attached Fig.10 -Attached Fig.11 The collecting pipe 14 includes a first horizontal portion 15 and a second horizontal portion 16. The second horizontal portion 16 is sleeved inside the swinging pipe 10. A symmetrical outer water inlet groove 13 is opened on the outer wall of the swinging pipe 10. A symmetrical inner water inlet groove 17 is opened on the outer wall of the second horizontal portion 16. The outer water inlet groove 13 and the inner water inlet groove 17 are staggered.

[0041] In this embodiment: since the second horizontal portion 16 is sleeved inside the swinging tube 10 and abuts against the inner wall of the swinging tube 10, when the loading plate 12 swings, the wastewater in the wastewater pool 2 can be drained into the inside of the swinging tube 10. When the loading plate 12 on the left swings from the bottom to the top, the wastewater flows to the middle through the loading plate 12. When the loading plate 12 on the left swings upward from the horizontal position, the outer water inlet trough 13 on the left partially overlaps with the inner water inlet trough 17 on the left, and the wastewater enters the swinging tube 10. At this time, the outer water inlet trough 13 on the right does not overlap with the inner water inlet trough 17 on the right, and the wastewater in the swinging tube 10 will not flow back to the loading plate 12 on the right. When the loading plate 12 on the left swings downward from the horizontal position, the outer water inlet trough 13 on the left does not overlap with the inner water inlet trough 17 on the left, and the wastewater in the swinging tube 10 will not flow back to the loading plate 12 on the left. At this time, the outer water inlet trough 13 on the right side partially overlaps with the inner water inlet trough 17 on the right side, and the waste water on the loading plate 12 flows into the swing pipe 10.

[0042] See attached Figure 1 -Attached Figure 3 A cylinder 18 is also installed on the outer wall of the second vertical frame 40. A cap 19 that cooperates with the flip cylinder 30 is fixedly provided at the output end of the cylinder 18. A hole groove 20 that cooperates with the first horizontal part 15 is opened on the cap 19. The first horizontal part 15 passes through the hole groove 20 and extends into the interior of the flip cylinder 30.

[0043] In this embodiment, when the feeding plate 12 swings, the turning cylinder 30 drives the wastewater to rotate intermittently clockwise and counterclockwise. In the gap of reversing, the cylinder 18 is started to make the cap 19 separate from the turning cylinder 30, and the wastewater in the turning cylinder 30 falls into the collecting part 33 below.

[0044] See attached Figure 3 and attached Fig.10The outer gear ring 23 is provided with an outer gear portion 25, and the inner gear 24 is provided with an inner gear portion 26; the outer gear portion 25 occupies half of the outer gear ring 23, and the inner gear portion 26 occupies half of the inner gear 24, and the positions of the outer gear portion 25 and the inner gear portion 26 are opposite.

[0045] In this embodiment: the diameter of the inner gear 24 is twice that of the flip gear 28, and the diameter of the outer gear ring 23 is four times that of the flip gear 28. Under the linkage of the belt 29, the output end of the motor 8 rotates one circle, and the loading plate 12 swings twice. When the left side of the loading plate 12 swings from the bottom to the top, the inner tooth portion 26 on the inner gear 24 meshes with the flip gear 28, and the flip cylinder 30 drives the wastewater to rotate clockwise. Since the inner tooth portion 26 occupies half of the inner gear 24, the flip cylinder 30 will rotate one circle. When the left side of the loading plate 12 swings from the top to the bottom, the outer tooth portion 25 on the outer gear ring 23 meshes with the flip gear 28, and the flip cylinder 30 drives the wastewater to rotate counterclockwise. Since the outer tooth portion 25 occupies half of the outer gear ring 23, the flip cylinder 30 will rotate two circles.

[0046] See attached Figure 8 -Attached Fig.10 A sampling rack 32 is fixedly arranged at the bottom of the horizontal frame 41, and a collecting portion 33 located below the flip cylinder 30 is arranged at the bottom of the sampling rack 32. A plurality of discharge ports 34 are arranged at intervals at the bottom of the collecting portion 33. A control valve 35 is installed in the middle of the discharge port 34, and a sensor 37 located below the control valve 35 is also installed on the inner wall of the discharge port 34; a sampling tube 36 is also threadedly installed at the bottom of the discharge port 34.

[0047] In this embodiment: In order to perform separate detection and sample preservation on each extracted wastewater sample, multiple groups of discharge ports 34 are arranged at intervals at the bottom of the collecting part 33. When the cylinder 18 drives the cap 19 to detach from the flip cylinder 30, the cap 19 slides outward along the first horizontal part 15 in cooperation with the hole groove 20 and the first horizontal part 15. At this time, the stirred wastewater will fall into the collecting part 33 below, and then the corresponding control valve 35 will be opened. The wastewater is stored in the sampling tube 36, and the sensor 37 detects the wastewater, and the detection structure will be sent to the control panel 38. In order to facilitate the removal and disassembly of the sampling tube 36, the sampling tube 36 is threadedly installed at the bottom of the discharge port 34.

[0048] See attached Figure 3 and attached Figure 6 A water pump 21 is also installed in the middle of the collecting pipe 14.

[0049] In this embodiment, in order to guide the wastewater collected by the swing pipe 10 into the turning drum 30 for stirring treatment, a water pump 21 is provided in the middle of the collecting pipe 14 .

[0050] See attached Figure 7 and attached Fig.10 A plurality of partition plates 31 are also provided on the inner wall of the turning cylinder 30 .

[0051] In this embodiment, in order to further improve the stirring effect and thus reduce the detection error of wastewater, multiple groups of partition plates 31 are designed.

[0052] See attached Figure 1 Attached Figure 2 A control panel 38 is also provided on the outer wall of the mounting frame 1 , a first bearing 42 cooperating with the swing tube 10 is provided on the lower swing seat 3 , and a second bearing 43 cooperating with the flip shaft 27 is provided on the upper hanging plate 4 .

[0053] In this embodiment, in order to control the overall operation of the device, a control panel 38 is designed. In order to ensure that the swing tube 10 can rotate freely relative to the lower swing seat 3, a first bearing 42 is designed. In order to ensure that the tilting shaft 27 can rotate freely relative to the upper hanging plate 4, a second bearing 43 is designed.

[0054] Working principle of the present invention: When the device is used, the mounting frame 1 is first fixed to the top of the wastewater pool 2, and then the control panel 38 and the motor 8 are started. When the motor 8 is started, the swing fan 6 drives the swing tube 10 and the loading plate 12 to swing back and forth. At the same time, driven by the belt 29, the outer gear ring 23 and the inner gear 24 also drive the turning cylinder 30 to rotate intermittently. When the loading plate 12 on the left side swings from the bottom to the top, the wastewater flows to the middle through the loading plate 12. When the loading plate 12 on the left side swings upward from the horizontal position, the outer water inlet trough 13 on the left side overlaps with the inner water inlet trough 17 on the left side, and the wastewater on the loading plate 12 on the left side enters the swing tube 10. At this time, under the action of the water pump 21, the wastewater enters the turning cylinder 30 through the collecting pipe 14. When the left side of the loading plate 12 swings from the bottom to the top, the inner tooth portion 26 on the inner gear 24 meshes with the turning gear 28, and the turning cylinder 30 drives the wastewater to rotate clockwise. When the left loading plate 12 swings downward from the horizontal position, the left outer water inlet trough 13 does not overlap with the left inner water inlet trough 17, and the wastewater in the swing tube 10 does not flow back to the left loading plate 12. At this time, the right outer water inlet trough 13 partially overlaps with the right inner water inlet trough 17, and the wastewater on the right loading plate 12 flows into the swing tube 10. When the left side of the loading plate 12 swings from the top to the bottom, the outer tooth portion 25 on the outer gear ring 23 meshes with the flip gear 28, and the flip cylinder 30 drives the wastewater to rotate counterclockwise. In the gap of reversing, the cylinder 18 is started to make the cap 19 detach from the flip cylinder 30, and the wastewater in the flip cylinder 30 falls into the collection portion 33 below. After the wastewater flows out, the cylinder 18 is started again to make the cap 19 seal the side of the flip cylinder 30. At this time, the stirred wastewater will fall into the collecting part 33 below, and then the corresponding control valve 35 will be opened, and the wastewater will be stored in the sampling tube 36 while the sensor 37 will detect the wastewater. When all the sampling tubes 36 store the wastewater samples, the detection operation is completed.
