Description

Technical Field

[0001] This invention belongs to the field of water quality testing technology, and in particular relates to a water conveyance channel with a water quality testing system. Background Technology

[0002] In wastewater treatment systems, the various treatment ponds are mostly connected by water conveyance channels. After the wastewater is treated in the upstream treatment pond, it is transported through the water conveyance channels and discharged to the downstream treatment pond for further treatment. During this process, the water quality needs to be tested.

[0003] The parameters for wastewater quality testing include monitoring pH, dissolved oxygen, conductivity, and turbidity. Other parameters require slightly lower precision in the depth of water sample testing. Currently, turbidity detection relies on a turbidimeter. Turbid substances in the water sample cause light to scatter. By measuring the intensity of the scattered light perpendicular to the incident light and comparing it with the internal calibration value, the turbidity in the water sample can be calculated. After linearization, the final value is output.

[0004] For turbidity parameters, since the pressure is different at different water source depths, there will be a large difference in turbidity at different water source depths.

[0005] In existing technologies, when detecting turbidity at different depths, it is necessary to sample the wastewater at the corresponding depth before measurement can be performed. Most of the sampling operations are carried out manually, which is inefficient, labor-intensive, and requires precise control of accuracy, resulting in a time-consuming, labor-intensive, and inflexible sampling process. Summary of the Invention

The testing instrument is slidably connected inside the testing pipe. Multiple inlets are distributed along the axis of the testing pipe, the bottom surface of the testing pipe is closed, and at least one outlet is provided on the bottom surface of the testing pipe.

When the pressure inside the testing pipe switches to a negative pressure state, one inlet is opened and all outlets are closed.

[0008] Furthermore, it also includes a support assembly, which includes two coaxially arranged support rods with a fixing ring between the two support rods.

[0013] Furthermore, at least one side of the fixing ring is connected to the support rod via a horizontal adjustment assembly.

[0014] Furthermore, the leveling assembly includes a level sensor, a set of meshing worm gears and worms, and a second housing located between the fixed ring and the support rod; the level sensor is directly or indirectly connected to the fixed ring; the worm is rotatably connected to the interior of the second housing; a rotating shaft extends from the fixed ring to the interior of the second housing, and the worm gear is coaxial with and fixedly connected to the rotating shaft; one side of the second housing is fixedly connected to the support rod, and the other side is rotatably connected to the rotating shaft; the leveling assembly also includes a rotation drive and a rotation controller, the rotation controller being communicatively connected to the rotation drive and the level sensor, and the rotation drive being driven by the worm; when the level sensor detects that the level of the fixed ring exceeds a threshold range, the worm drives the worm gear, which in turn drives the fixed ring to start rotating, until the level sensor detects that the level of the fixed ring is within the threshold range; several threaded holes are provided on the side wall of the fixed ring, and bolts for clamping the detection pipe are fitted into the threaded holes.

[0015] Furthermore, the control component includes a connecting block with an inner cavity, which is detachably connected to the upper end of the detection pipe.

Detailed Implementation

[0021] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0022] like Figure 1-8 As shown, the present invention provides a water conveyance channel with a water quality testing system, which can test water at different depths at the same location within the water conveyance channel 3. The water quality testing system is supported on the water conveyance channel. The water quality testing system includes a testing pipe 1 with graduations on its outer wall and a testing instrument 2, which is slidably connected inside the testing pipe 1.

[0023] During testing, the testing pipe 1 extends vertically downwards into the water near the side wall of the water conveyance channel 3, providing a safe testing space for the testing instrument 2. This prevents damage from hard objects such as stones in the water, steel bars extending from the side wall of the water conveyance channel 3, or entanglement with debris in the water, which could affect the testing process. Simultaneously, the depth of the lower end of the testing pipe 1 from the water surface is determined by the markings on its outer wall.

[0024] like Figure 1 , Figure 2 As shown, a support assembly 4 is provided on the water conveyance channel 3. The support assembly 4 includes two coaxially arranged support rods 43, and a fixing ring 44 is provided between the two support rods 43. When the fixing ring 44 is rotated to a horizontal position, it can be fixed, so that the detection pipe 1 is vertically fixed on the fixing ring 44 by extending into the fixing ring 44. The rotation axis of the fixing ring 44 is the axis of the support rods 43.

[0025] The support assembly 4 also includes two telescopic rods 41 detachably fixed to the ground near the side wall of the water conveyance channel 3, and two positioning rods 42 hinged to the telescopic rods 41. Each telescopic rod 41 includes an inner rod 411 and an outer rod 412 coaxially sleeved. Two support rods 43 are fixed between the two inner rods 411. A fixing plate 414 is provided on the side of the two outer rods 412 away from the telescopic end. The fixing plate 414 is detachably fixed to the ground on the upper side of the water conveyance channel 3 to secure the support assembly 4 to the water conveyance channel 3.

[0026] A positioning rod 42 is located on the lower side of the telescopic rod 41. The upper end of the positioning rod 42 is hinged to the outer rod 412. The rotation axis of the positioning rod 42 is parallel to the axis of the support rod 43, so that the positioning rod 42 can fit against the side wall of the water conveyance channel 3. Several positioning grooves 421 are provided on the positioning rod 42. A support rod 413 is hinged to the inner rod 411. The support rod 413 is engaged in the positioning grooves 421 to provide support for the inner rod 411. The rotation axis of the support rod 413 coincides with the axis of the support rod 43.

[0027] During installation, the fixing plate 414 is fixed to the ground. Next, the inner rod 411 is pulled out. The length pulled out is related to the slope of the side wall of the water conveyance channel 3; the greater the slope, the longer the length pulled out. The positioning rod 42 is hinged to the outer rod 412. After the outer rod 412 is fixed, the positioning rod 42 will naturally hang down along the side wall of the water conveyance channel 3. The end of the inner rod 411 is hinged to a support rod 413. When the inner rod 411 is pulled out to the specified length, the support rod 413 is engaged in different positioning slots 421 to provide support for the inner rod 411. This, in turn, causes the support rod 43 to receive support from the support rod 413. While improving the stability of the support rod 43, the support rod 413 can also limit the extension length of the inner rod 411 to a certain extent, thus improving the stability of the inner rod 411.

[0028] Since the positioning rod 42 and the outer rod 412 are hinged, the angle between them can always be adjusted to match the inclination angle of the side wall of the water conveyance channel, thereby ensuring the stability of the support assembly 4 on the water conveyance channel.

[0029] The outer rod 412, which plays a major supporting role, is fixed to the ground above the water conveyance channel by a fixing plate 414, such as by screws.

[0030] A fixing ring 44 is provided on the support rod 43, and the rotation axis of the fixing ring 44 is the axis of the support rod 43. When the fixing ring 44 is rotated to the horizontal position, it can be fixed. The detection pipe 1 is detachably connected to the fixing ring 44, and the two are coaxial, so that the detection pipe 1 is vertically supported in the water conveyance channel 3 by extending into the fixing ring 44.

[0031] Specifically, at least one side of the fixed ring 44 is connected to the support rod 43 via a horizontal adjustment assembly 45. The horizontal adjustment assembly 45 includes a horizontal sensor 453, a set of meshing worm gears 454 and worm 455, and a second housing 451 located between the fixed ring 44 and the support rod 43; the horizontal sensor 453 is directly or indirectly connected to the fixed ring 44; the worm 455 is rotatably connected to the interior of the second housing 451; the rotating shaft 300 extends from the fixed ring 44 to the interior of the second housing 451, and the worm gears 454 are coaxial with and fixedly connected to the rotating shaft 300; one side of the second housing 451 is fixedly connected to the support rod 43, and the other side is rotatably connected to the rotating shaft 300; The leveling assembly 45 also includes a rotation drive and a rotation controller. The rotation controller is communicatively connected to the rotation drive and the level sensor 453. The rotation drive is driven by the worm gear 455. When the level sensor 453 detects that the level of the fixed ring 44 exceeds the threshold range, the worm 455 drives the worm wheel 454, which in turn drives the fixed ring 44 to start rotating, until the level sensor 453 detects that the level of the fixed ring 44 is within the threshold range. The side wall of the fixing ring 44 has several threaded holes, and bolts 441 for clamping the test pipe 1 are fitted into the threaded holes.

[0032] In this embodiment, a rotating shaft 300 extends from the fixed ring 44, and the horizontal sensor 453 is fixed on the rotating shaft 300. The rotating shaft 300 extends into the interior of the second housing 451 and is fixedly connected to the worm gear 454. The two are coaxial. When the worm 455 drives the worm gear 454 to rotate, the fixed ring 44 will also rotate to adjust the level of the fixed ring 44, thereby ensuring that the detection pipe 1 is set in the vertical direction.

[0033] Specifically, when the horizontal sensor 453 detects, it outputs an electrical signal. The rotation controller receives and processes the electrical signal to determine and calculate the rotation direction and duration of the rotation drive component. This determines the number of rotations required for the worm gear 455 to rotate, which in turn drives the worm wheel 454 to swing the fixed ring 44 by the required angle, thereby adjusting the longitudinal axis of the fixed ring 44 to a vertical state.

[0034] More specifically, the rotation drive can be set as a small servo motor. Since the transmission ratio between the worm 455 and the worm wheel 454 can be easily set to a large value, the adjustment accuracy of this leveling component 45 can also be set to a high value.

[0035] Meanwhile, the self-locking characteristic of the transmission between the worm gear 454 and the worm 455 can be utilized so that the swing angle of the fixed ring 44 can only be adjusted by rotating the worm 455. Thus, during the use of this water quality testing system, under the premise that the testing pipe 1 is well fixed, even if the testing pipe 1 is hit, it can still maintain a vertical state without swinging, thereby improving the reliability of the water quality testing system.

[0036] In this embodiment, by engaging the support rod 413 into the specific positioning groove 421, the level of the fixed ring 44 can be coarsely adjusted. The horizontal adjustment component 45 drives the swing of the fixed ring 44 to achieve fine adjustment of the level of the fixed ring 44. This can better ensure the verticality of the detection pipe 1 inside the fixed ring 44, improve the fit between the marked height and the actual depth of its inlet 100 in the wastewater, and thus improve the accuracy of water sampling at the specified depth.

[0037] The side wall of the fixing ring 44 has several threaded holes, and bolts 441 for clamping the test pipe 1 are fitted into the threaded holes.

[0038] A control component 11 is detachably connected to the top of the detection pipe 1 to adjust the water level inside the detection pipe 1.

[0039] Multiple inlets 100 are distributed along the longitudinal axis of the detection pipeline 1, enabling each inlet 100 to extract wastewater at a corresponding depth, thus completing the detection of wastewater at different depths. The bottom surface of the detection pipeline 1 is closed, and at least one outlet 200 is provided on the bottom surface of the closed detection pipeline 1. Each inlet 100 and outlet 200 is controlled to open and close by a solenoid valve.

[0040] The control component 11 can switch the pressure inside the detection pipe 1 between a positive pressure state that is greater than the external air pressure or a negative pressure state that is less than the external air pressure. When the pressure in the detection pipeline 1 switches to a positive pressure state, all inlets 100 are closed and at least one outlet 200 is opened; when the pressure in the detection pipeline 1 switches to a negative pressure state, one inlet 100 is opened and all outlets 200 are closed.

[0041] Specifically, such as Figure 5 , Figure 6 As shown, the control assembly 11 includes a connecting block 111 with an inner cavity and two diaphragm pumps 112 disposed within the inner cavity, which are an intake pump and an exhaust pump, respectively. The connecting block 111 is detachably connected to the upper end of the detection pipe 1. The upper end of the detection pipe 1 is provided with a first internal thread, and the outer surface of the connecting block 111 is provided with a second external thread, which matches the first internal thread, allowing the connecting block 111 to be detachably connected to the upper end of the detection pipe 1. Figure 5-6 As shown, both diaphragm pumps 112 include an air extraction pipe 1121, which connects the inner cavity of the detection pipe 1 to the outside. The two air extraction pipes 1121 have opposite air extraction directions to adjust the water level in the detection pipe 1.

[0042] Both the intake pump and the exhaust pump are connected to the pump controller, and they do not operate simultaneously. When the intake pump is operating, all inlets 100 are closed, and at least one outlet 200 is open. When the exhaust pump is operating, one inlet 100 is open, and all outlets 200 are closed, thereby achieving control over the inlet and outlet of the detection pipe 1.

[0043] like Figure 7-8 As shown, the detector 2 includes a first housing 21 and a plurality of detection probes 22, a plurality of detection blocks and an umbrella head 23 correspondingly connected to the plurality of detection probes 22. The plurality of detection blocks are all fixed and sealed within the cavity of the first housing 21. The plurality of detection probes 22 and the plurality of detection blocks are of various types to meet the detection requirements of various indicators, such as a turbidity detection module, a temperature detection module, a pH detection module, etc. The plurality of detection probes 22 are all positioned downwards and extend from the lower end of the first housing 21.

[0044] Preferably, the detector 2 further includes a protective cover 24 that is directly or indirectly connected to the first housing 21. The connection port of the protective cover 24 is provided with an internal thread, and the lower end of the first housing 21 is provided with an external thread. The first housing 21 and the protective cover 24 are threadedly connected to cover a number of detection probes 22 inside, so as to prevent the detector 2 from being damaged by impurities in the water when it is conducting detection in the water.

[0045] like Figure 5 As shown, during the test, the detector 2 floats vertically on the water surface in the detection pipe 1. Figure 5 , Figure 7-8As shown, the umbrella head 23 is detachably fixed to the upper end of the first outer shell 21. The umbrella head 23 has a cavity 231 inside, which can increase the buoyancy of the detector 2, so that the detector 2 floats at the water surface height in the detection pipe 1.

[0046] When preparing for testing, insert the lower end of the testing pipe 1 into the wastewater, turn on the exhaust pump to extract the gas in the testing pipe 1 to the outside, then open the inlet 100 at the water depth to be measured, and at the same time close all the outlets, pump the water at the water depth to be measured into the testing pipe 1 until the water surface submerges the testing probe 22.

[0047] The umbrella head 23 is slidably connected to the detection pipe 1, and there is a flow channel between the two so that the air or liquid on the upper and lower sides of the umbrella head 23 can flow to each other, thereby connecting the upper and lower spaces of the umbrella head 23 into one.

[0048] During wastewater testing, when wastewater enters the testing pipe 1 through the inlet 100, which is higher than the umbrella head 23, the waste liquid can flow from above the umbrella head 23 through the flow channel to below the umbrella head 23, causing the detector 2 itself to float. Then, the turbidity of the water sampled at a specific depth can be measured.

[0049] During the wastewater discharge process, the air pump works, and gas can flow from above the umbrella head 23 through the flow channel to below the umbrella head 23. Under the action of pressure, the wastewater is discharged from the detection pipe 1 through the outlet 200.

[0050] Specifically, the flow channel can be set as a flow groove opened on the outer edge of the umbrella head 23 or on the inner wall of the detection pipe 1.

[0051] After the test is completed, all inlets 100 need to be closed and at least one outlet 200 needs to be opened to drain the water from the test pipe 1.

[0052] During the water inlet process of the detection pipeline 1, wastewater at different depths can be detected by opening the inlet ports 100 at different depths.

[0053] To ensure that all wastewater is discharged and that it completely covers the detection probe, the intake and exhaust pumps need to operate for a certain duration, taking into account their pumping and drainage volumes per unit time. This ensures that the amount of water pumped by the exhaust pump covers the detection probe, and that the intake pump ensures that all wastewater is reliably discharged.

[0054] The power source for each electronic control module can be a storage battery installed on the water conveyance channel.
