Description

Technical Field

[0001] This invention relates to a wastewater discharge monitoring system, specifically a monitoring system for urban wastewater discharge, and relates to the technical field of wastewater treatment and discharge. Background Technology

[0002] Wastewater refers to wastewater discharged from domestic and industrial sources that has been polluted to some extent. Water that has lost its original function is simply called wastewater. It mainly consists of water used for domestic purposes, containing a relatively high amount of organic matter, and is relatively easy to treat. During the wastewater discharge process, in order to ensure that the wastewater meets discharge standards, monitoring and sampling devices are generally installed at the wastewater discharge point to monitor and sample the wastewater.

[0003] However, existing wastewater monitoring devices still have some problems. Most existing monitoring devices install multiple sampling devices at the discharge outlet to monitor the discharged wastewater. However, in actual operation, since wastewater is placed in a storage tank for chemical dosing or microbial degradation or reaction of substances in the water, the storage tank has a certain depth. Therefore, during the drainage process, the flow rate of wastewater is related to the water content in the storage tank. When there is more water in the storage tank, the water flow rate at the discharge outlet is faster, and vice versa. Since the number of sampling devices operating at the existing discharge outlet is limited, this can lead to too few samples being collected when the flow rate is high, and too many samples being collected when the flow rate is low, which can easily result in waste.

[0004] Therefore, how to select the appropriate number of sampling devices based on the flow rate of sewage is a problem that needs to be solved. Summary of the Invention

[0005] Purpose of the invention: To provide a monitoring system for urban sewage discharge to solve the above-mentioned problems existing in the prior art.

[0006] Technical solution: A monitoring system for urban sewage discharge, comprising:

[0007] Water storage tank, connecting pipes, monitoring unit, water outlet pipe, and multiple sampling devices;

[0008] The monitoring unit includes a support tube, a measuring mechanism disposed inside the support tube, and a control device connected to the measuring mechanism;

[0009] The measuring mechanism includes a mounting frame connected to the support tube, a rotating part connected to the mounting frame, a plurality of rotating fan blades disposed at one end of the rotating part, a transmission assembly connected to the other end of the rotating part, a rotating part connected to the transmission assembly, and a counting part connected to the control device.

[0010] The sampling device is electrically connected to the control equipment;

[0011] The counting unit is used to record the number of rotations of the rotating part;

[0012] One end of the connecting pipe is connected to the water storage tank, and the other end is connected to the support pipe. A valve is provided at the connection between the connecting pipe and the water storage tank. One end of the outlet pipe is connected to the support pipe.

[0013] The sampling device is located inside the water outlet pipe;

[0014] At least when urban sewage is discharged, the water flow in the storage tank drives the rotating fan blades through the connecting pipes, and then the rotating part is driven by the transmission component. The counting unit then feeds back the number of rotations of the rotating part to the control equipment, which then selects the appropriate number of sampling devices based on the actual number of rotations of the rotating part, and then samples and monitors the quality of the discharged sewage.

[0015] In a further embodiment, the rotating part includes a transmission member disposed on the mounting bracket, a rotating shaft passing through the transmission member, and a rotating frame connected to one end of the rotating shaft.

[0016] The rotating frame is cylindrical, and the rotating fan blades are detachably installed on the circumference of the rotating frame, with the rotating fan blades having a predetermined curvature.

[0017] The other end of the rotating shaft is connected to the transmission assembly;

[0018] The mounting bracket has a hexagonal prism structure.

[0019] In a further embodiment, the mounting frame is also provided with a plurality of support parts in the circumferential direction, a plurality of telescopic cylinders symmetrically mounted on the mounting frame, and a limiting strip with a predetermined arc connected to the output end of the telescopic cylinder;

[0020] The support unit includes a hinge seat located circumferentially on the mounting frame, a set of connecting shafts symmetrically mounted on the hinge seat, a support frame mounted on the connecting shaft, a limiting wheel mounted on the support frame, and a support spring for connecting two support frames on the same support unit; it enables the limiting strip to abut against the inner wall of the support tube, thereby preventing the measuring unit from shifting inside the support tube, thus ensuring that the rotating fan blade can rotate normally, and at the same time, it can adjust the position of the support unit in the support tube, thereby allowing the position of the rotating fan blade to be adjusted according to the actual situation.

[0021] In a further embodiment, the transmission assembly includes a protective tube connected to the mounting bracket, an input shaft located on the protective tube, an adjustment part connected to the input shaft, and an output shaft connected to the adjustment part;

[0022] The input shaft is connected to the other end of the rotating shaft;

[0023] The output shaft is connected to the rotating part; the protective tube provided can prevent damage to the parts inside the protective tube, thereby ensuring the smooth operation of the device.

[0024] In a further embodiment, the adjusting part includes a set of first rotating disks disposed inside the protective tube, and a plurality of transmission parts for connecting the first rotating disks;

[0025] The axis of one of the first rotating disks is parallel to the axis of the other rotating disk;

[0026] Both the transmission part and the protective tube are L-shaped.

[0027] In a further embodiment, the transmission part includes a second connecting rod, connectors symmetrically mounted at both ends of the second connecting rod, a first connecting rod connected to one of the connectors, and a third connecting rod connected to the other connector.

[0028] The first connecting rod passes through the first rotating disk and reciprocates along the axis of the first rotating disk.

[0029] The third connecting rod passes through another first rotating disk and reciprocates along the axis of the first rotating disk;

[0030] At least in the working state, when the first connecting rod extends from one side of the first rotating disk, the third connecting rod retracts into the first rotating disk to which it is connected; it can not only complete the monitoring of water flow, but also select the appropriate number of sampling devices according to its flow rate, thereby avoiding an increase in enterprise costs.

[0031] In a further embodiment, the first rotating disk is further provided with a limiting sleeve in the circumferential direction, and the limiting sleeve is further provided with a plurality of limiting grooves and a limiting ball placed in the limiting grooves;

[0032] The limiting ball abuts against the inner wall of the protective tube to avoid excessive friction causing the transmission part to stop moving, thereby enabling the selection of an appropriate number of sampling devices based on the actual fluid flow rate.

[0033] In a further embodiment, at least two second rotating disks with the same structure as the first rotating disk are also sleeved on the second connecting rod;

[0034] At least four stop blocks are also symmetrically installed along the axial direction of the second rotating disk.

[0035] In a further embodiment, the number of transmission parts is seven, one of which has its axis coincident with the axis of the input shaft;

[0036] The remaining six transmission units are evenly distributed around the first rotating disk, and the distance from the axis corresponding to the above six transmission units to the axis of the input shaft is the same.

[0037] A monitoring method based on the aforementioned urban sewage discharge monitoring system includes the following steps:

[0038] S1: In order to monitor the sewage discharged from the city, it is necessary to monitor the sewage to be discharged before the sewage discharge work. Therefore, it is necessary to install the measuring device in the monitoring unit and complete the installation of the monitoring unit.

[0039] S2: When the monitoring unit needs to be installed, first place one of the limiting wheels from the multiple support parts into the support tube in sequence. Then, the installer pulls the other limiting wheel from the support part toward the axis of the mounting frame, so that the mounting frame is located inside the support tube. At this time, the support spring is in a deformed state, which allows the mounting frame to be located inside the support tube. Then, the installer pushes the mounting frame, so that the mounting frame moves upward along the axis of the support tube. When the rotating fan is in the predetermined position, the rotating cylinder on the mounting frame starts to work. The moving rotating cylinder drives the limiting strip to start moving, so that the limiting strip abuts against the inner wall of the support tube, thereby completing the fixation of the mounting frame position and completing the preliminary installation work for the sewage monitoring.

[0040] S3: After the installation of the monitoring unit is completed, the urban wastewater is first stored in the storage tank. Then, medicines or other disinfectants are added to the storage tank to disinfect the wastewater. After standing for a period of time, the valve starts to move, allowing the wastewater in the storage tank to move along the connecting pipe and then the flowing wastewater to the monitoring unit.

[0041] S4: When the sewage moves to the monitoring unit, the rotating fan blades have a certain curvature. When the water flows over the rotating fan blades, the rotating fan blades will start to rotate. The rotating fan blades can drive the rotating frame to start rotating. The rotating frame can drive the rotating shaft to start moving. The rotating shaft can drive the transmission components to start working.

[0042] S5: When the rotating shaft starts to rotate, the rotating shaft can drive the input shaft connected to it to start rotating. The rotating input shaft can drive the first rotating disk connected to it to start moving. When the first rotating disk rotates, the first rotating disk can drive multiple first connecting rods provided on the first rotating disk to start moving. Then the moving first connecting rod can drive the second connecting rod to start rotating. The moving second connecting rod can drive the third connecting rod to start rotating. The moving third connecting rod can drive another first rotating disk connected to it to start moving, which in turn can drive the output shaft to start moving.

[0043] S6: When the output shaft starts to move, the moving output shaft can drive the rotating part connected to it to start moving. Then the counting unit can record the number of rotations of the rotating part within a predetermined time and send the recorded number of rotations of the rotating part to the control device.

[0044] S7: When the control equipment receives the signal received by the counting unit, it can select the corresponding number of sampling devices to sample and detect the water flow into the outlet pipe based on the number of rotations. This not only enables the monitoring of the water flow, but also allows the selection of the corresponding number of sampling devices based on the flow rate, thereby avoiding increased costs for the enterprise.

[0045] Beneficial Effects: This invention discloses a monitoring system for urban sewage discharge. To select the appropriate number of sampling devices based on the sewage flow rate, the system includes a monitoring unit. The impact between the rotating fan blades and the water flow within the monitoring unit drives the fan blades to rotate. This rotating fan blades then activate a transmission component, which in turn drives the rotating part to operate. A counting unit records the number of rotations of the rotating part within a predetermined time and sends this record to a control device. Upon receiving the signal from the counting unit, the control device selects the appropriate number of sampling devices based on the rotation count to sample the water flowing into the outlet pipe. This system not only monitors the water flow but also selects the appropriate number of sampling devices based on the flow rate, preventing issues of insufficient or excessive sample quantities. It allows for real-time control of the number of operating sampling devices, thus completing the sewage sampling and collection process. Attached Figure Description

[0053] Based on the applicant's research and analysis, the reason for this problem (the limited number of sampling devices at existing sewage outlets leads to insufficient sample collection at high flow rates and excessive sample collection at low flow rates, resulting in waste) is that existing monitoring devices typically install multiple sampling devices at the sewage outlet to monitor the discharged wastewater. However, in actual operation, the wastewater is placed in a storage tank for drug administration or microbial degradation or reaction of substances in the water. Therefore, the storage tank has a certain depth, and the sewage flow rate is related to the water content in the storage tank. When there is more water in the storage tank, the sewage flow rate at the outlet is faster, and vice versa. Thus, the sewage flow rate varies. This invention aims to select the appropriate number of sampling devices based on the sewage flow rate. The sampling device includes a monitoring unit. The impact between the rotating fan blades and the water flow within the monitoring unit causes the fan blades to rotate. This rotation of the fan blades then activates a transmission assembly, which in turn drives the rotating part to operate. A counting unit records the number of rotations of the rotating part within a predetermined time and sends this record to a control device. Upon receiving the signal from the counting unit, the control device selects an appropriate number of sampling devices based on the number of rotations to sample the water flowing into the outlet pipe. This not only monitors the water flow but also allows for the selection of an appropriate number of sampling devices based on the flow rate, preventing issues of insufficient or excessive sample quantities. The device enables real-time control of the number of operating sampling devices, thus completing the sampling and collection of wastewater.

[0054] A monitoring system for urban sewage discharge includes: a water storage tank 1, a connecting pipe 2, a monitoring unit 3, a support pipe 31, a measuring mechanism 32, a mounting frame 321, a support part 322, a hinge seat 3221, a support frame 3222, a limiting wheel 3223, a support spring 3224, a connecting shaft 3225, a transmission component 323, a rotating shaft 324, a rotating frame 325, a rotating fan blade 326, a transmission assembly 327, an input shaft 3271, a protective pipe 3272, a first rotating disk 3273, a limiting sleeve 3274, a limiting ball 3275, a transmission part 3276, a first connecting rod 32761, a second connecting rod 32762, a third connecting rod 32763, a connecting part 32764, a second rotating disk 3277, an output shaft 3278, a stop block 3279, a control device 33, a water outlet pipe 4, and a valve 5.

[0055] This device includes a water storage tank 1, a connecting pipe 2, a monitoring unit 3, a water outlet pipe 4, and multiple sampling devices. The monitoring unit 3 includes a support pipe 31, a measuring mechanism 32 disposed within the support pipe 31, and a control device 33 connected to the measuring mechanism 32. The measuring mechanism 32 includes a mounting frame 321 connected to the support pipe 31, a rotating part connected to the mounting frame 321, multiple rotating fan blades 326 disposed at one end of the rotating part, a transmission assembly 327 connected to the other end of the rotating part, and a rotary fan blade connected to the transmission assembly 327. The rotating part and the counting part connected to the control device 33; the sampling device is electrically connected to the control device 33; the counting part is used to record the number of rotations of the rotating part; one end of the connecting pipe 2 is connected to the water storage tank 1, and the other end is connected to the support pipe 31. A valve 5 is provided at the connection between the connecting pipe 2 and the water storage tank 1. One end of the outlet pipe 4 is connected to the support pipe 31; the sampling device is located inside the outlet pipe 4; at least when discharging urban sewage, the water flow in the water storage tank 1 drives the rotating fan blade 326 to rotate through the connecting pipe 2, and then passes through the transmission assembly 327. The rotating part is driven to rotate, and the counting part feeds back the number of rotations of the rotating part to the control device 33. The control device 33 then selects the appropriate number of sampling devices based on the actual number of rotations of the rotating part to sample and monitor the quality of the discharged wastewater. The counting part can record the number of rotations of the rotating part within a predetermined time and send the recorded number of rotations to the control device 33. When the control device 33 receives the signal from the counting part, it can then select the appropriate number of sampling devices to sample and detect the water flow into the outlet pipe 4 based on the number of rotations. This not only completes the monitoring of the water flow but also allows for the selection of the appropriate number of sampling devices based on the flow rate, thus avoiding the problem of insufficient or excessive sample quantity. This enables real-time control of the number of working sampling devices, thereby completing the sampling and collection of wastewater. Alternatively, the rotating part and the counting part can be replaced with a rotary encoder, which can directly convert the circular motion into a digital signal output and then transmit this digital signal to the control device, which then controls the appropriate number of sampling devices to operate.

[0056] The rotating part includes a transmission component 323 mounted on the mounting frame 321, a rotating shaft 324 passing through the transmission component 323, and a rotating frame 325 connected to one end of the rotating shaft 324; the rotating frame 325 is cylindrical, and the rotating fan blade 326 is detachably mounted on the circumferential direction of the rotating frame 325, the rotating fan blade 326 having a predetermined curvature; the other end of the rotating shaft 324 is connected to the transmission assembly 327; the mounting frame 321 has a hexagonal prism structure; the mounting frame 321 is also provided with multiple support parts 322 on its circumference, multiple telescopic cylinders symmetrically mounted on the mounting frame 321, and a limiting strip with a predetermined curvature connected to the output end of the telescopic cylinder; the support part 322 includes a component mounted on the mounting frame 321. A hinge seat 3221 with 21 circumferences upwards, a set of connecting shafts 3225 symmetrically mounted on the hinge seat 3221, a support frame 3222 provided on the connecting shaft 3225, a limiting wheel 3223 mounted on the support frame 3222, and a support spring 3224 for connecting two support frames 3222 on the same support part 322; In order to monitor the sewage discharged from the city, it is necessary to monitor the sewage to be discharged before the sewage discharge work. Therefore, it is necessary to install the measuring mechanism 32 in the monitoring unit 3 to complete the installation of the monitoring unit 3; When it is necessary to install the monitoring unit 3, first place one of the limiting wheels 3223 among the multiple support parts 322 into the support tube 31 in sequence, and then install. Personnel retract the other limiting wheel 3223 in the support 322 towards the axis of the mounting frame 321, thus positioning the mounting frame 321 inside the support tube 31. At this time, the support spring 3224 is in a deformed state, allowing the mounting frame 321 to be positioned inside the support tube 31. Then, the installer pushes the mounting frame 321, causing it to move axially upwards in the support tube 31. Once the rotating fan is in the predetermined position, the rotary cylinder on the mounting frame 321 begins to operate. The moving rotary cylinder drives the limiting strip to move, causing the limiting strip to abut against the inner wall of the support tube 31, thereby fixing the position of the mounting frame 321 and completing the preliminary installation work for the wastewater monitoring system. After completing the installation of the monitoring unit 3, the city... Municipal wastewater is stored in storage tank 1. Then, chemicals or other disinfectants are added to storage tank 1 to disinfect the wastewater. After a period of settling, valve 5 is activated, allowing the wastewater in storage tank 1 to flow along connecting pipe 2, eventually reaching monitoring unit 3. When the wastewater reaches monitoring unit 3, the rotating fan blades 326, due to their curvature, begin to rotate as water flows over them. The rotating fan blades 326 then drive the rotating frame 325 to rotate, which in turn drives the rotating shaft 324 to move, which in turn drives the transmission assembly 327 to operate.

[0057] In a further embodiment, when the water flow impacts the rotating fan blade 326, it not only drives the rotating fan blade 326 to rotate, but also applies a downward pressure to the rotating fan blade 326. Simultaneously, since the mounting frame 321 in this device has multiple support parts 322, and the axis of the limiting wheel 3223 in the support part 322 is perpendicular to the center line of the mounting frame 321, when the water flow applies a downward pressure to the rotating fan blade 326, the mounting frame 321 will slide within the support tube 31. This will cause the rotating fan blade 326 to become increasingly lower, eventually causing it to abut against the inner wall of the water outlet pipe 4, which could easily damage the device. Therefore, this device includes a telescopic cylinder and a limiting strip connected to the telescopic cylinder. During installation, the limiting strip abuts against the inner wall of the support tube 31, preventing the measuring unit from shifting within the support tube 31 and ensuring that the rotating fan blade 326 can rotate normally.

[0058] The transmission assembly 327 includes a protective tube 3272 connected to the mounting bracket 321, an input shaft 3271 located on the protective tube 3272, an adjusting part connected to the input shaft 3271, and an output shaft 3278 connected to the adjusting part; wherein the input shaft 3271 is connected to the other end of the rotating shaft 324; the output shaft 3278 is connected to the rotating part; the adjusting part includes a set of first rotating disks 3273 disposed within the protective tube 3272, and a plurality of transmission parts 3276 for connecting the first rotating disks 3273; the axis of one of the first rotating disks 3273 is parallel to the axis of another rotating disk; both the transmission part 3276 and the protective tube 3272 are "L" shaped; the transmission part 3276 includes a second connecting rod 32762, connectors 32764 symmetrically mounted at both ends of the second connecting rod 32762, a first connecting rod 32761 connected to one of the connectors 32764, and a third connecting rod 32763 connected to the other connector 32764; wherein the first connecting rod 32761 passes through the first rotating disk 3273 and reciprocates in the axial direction of the first rotating disk 3273; the third connecting rod 32763 passes through the other first rotating disk 3273 and reciprocates in the axial direction of the first rotating disk 3273; at least in the working state, when the first connecting rod 32761 extends from one side of the first rotating disk 3273, the third connecting rod retracts to the first rotating disk 3273. Within the first rotating disk 3273 connected to it; when the rotating shaft 324 starts to rotate, the rotating shaft 324 can drive the input shaft 3271 connected to it to start rotating, and the rotating input shaft 3271 can drive the first rotating disk 3273 connected to it to start moving. When the first rotating disk 3273 rotates, the first rotating disk 3273 can drive the multiple first connecting rods 32761 provided on the first rotating disk 3273 to start moving. Then, the moving first connecting rods 32761 can drive the second connecting rods 32762 to start rotating, and the moving second connecting rods 32762 can drive the third connecting rods 32763 to start rotating. The moving third connecting rods 32763 can drive the multiple first connecting rods 32761 connected to it to start moving. The first rotating disk 3273 starts to move, which in turn drives the output shaft 3278 to start moving. When the output shaft 3278 starts to move, it drives the rotating part connected to it to start moving. The counting unit records the number of rotations of the rotating part within a predetermined time and sends the recorded number of rotations to the control device 33. When the control device 33 receives the signal received by the counting unit, it can select the corresponding number of sampling devices to sample and detect the water flow into the outlet pipe 4 according to the number of rotations. This not only completes the monitoring of the water flow, but also allows the selection of the corresponding number of sampling devices according to the flow rate, thereby avoiding an increase in enterprise costs.

[0059] In a further embodiment, existing methods for measuring fluid velocity in pipelines mostly involve the interaction of a fan blade, a rotating shaft 324, and a gear set, which drives the rotating part connected to the gear set to move. However, due to the relatively humid environment in which this device is located, the gears in the gear set may rust, or due to the inherent characteristics of the meshing gears, when the water flow impact force is too small, the presence of the gear set acts as a braking mechanism, preventing the fan blade from rotating. Consequently, the number of sampling devices actually working is less than the number of sampling devices intended for operation, resulting in a small number of samples collected at this flow rate.

[0060] To solve the aforementioned problems, this device includes a transmission assembly 327, comprising at least two first rotating disks 3273, two second rotating disks 3277, a transmission part 3276, and a protective tube 3272. Firstly, the protective tube 3272 prevents water from corroding the transmission part 3276 within the transmission assembly 327. Secondly, through the interaction of the first rotating disks 3273, second rotating disks 3277, and transmission part 3276, and because there is no gear transmission in this device, no damage occurs during the transmission process. The device generates significant resistance, so as long as the water flow can drive the fan blades to rotate, the rotating disk can be driven by the transmission unit 3276. The counting unit can then record the number of rotations of the rotating disk. At the same time, since the rotating disk in this device has multiple limiting balls 3275 on its circumference, the surface contact can be converted into point contact, thereby reducing the friction between the transmission unit 3276 and the protective tube 3272. This avoids the situation where the transmission unit 3276 does not move due to excessive friction, and allows for the selection of an appropriate number of sampling devices based on the actual fluid flow rate.

[0061] In a further embodiment, when there is too much water in the water storage tank 1, the water flow will cause the rotating fan blade 326 to rotate faster, which will in turn cause the output shaft 3278 in the transmission assembly 327 to rotate faster, which will cause the rotating part to rotate too fast, thus requiring a high-quality technical part. The counting part can be a visual sensing device. The rotating part includes a drive component and a rotating disk, which will lead to excessive budget.

[0062] To solve the above problems and prevent the rotating part from rotating too fast, which would cause the counting part to be unable to perform accurate measurements, a first gear and a second gear are respectively provided on the output shaft 3278 and the rotating part. The first gear is sleeved on the output shaft 3278, and the second gear is connected to the connecting piece 32764. At the same time, the diameter of the first gear is smaller than the diameter of the second gear, which can reduce the rotation speed of the rotating disk and ensure that the counting part can complete the recording of the number of rotations of the rotating disk.

[0063] The first rotating disk 3273 is also provided with a limiting sleeve 3274 in the circumferential direction. The limiting sleeve 3274 is also provided with a plurality of limiting grooves and a limiting ball 3275 placed in the limiting grooves; the limiting ball 3275 abuts against the inner wall of the protective tube 3272.

[0064] The second connecting rod 32762 is also fitted with at least two second rotating disks 3277 with the same structure as the first rotating disk 3273; at least four stop blocks 3279 are also symmetrically installed on the second rotating disk 3277 in the axial direction.

[0065] There are seven transmission parts 3276, one of which has its axis coincident with the axis of the input shaft 3271; the remaining six transmission parts 3276 are evenly arranged around the first rotating disk 3273, and the distance from the axis corresponding to the above six transmission parts 3276 to the axis of the input shaft 3271 is the same.

[0066] Working Principle Description: To monitor urban wastewater discharge, it is necessary to monitor the wastewater before discharge. Therefore, the measuring mechanism 32 needs to be installed within the monitoring unit 3. When installing the monitoring unit 3, first, one of the limiting wheels 3223 from the multiple support parts 322 is placed sequentially inside the support tube 31. Then, the installer moves the other limiting wheel 3223 from the support part 322 towards the axis of the mounting frame 321, positioning the mounting frame 321 within the support tube 31. At this point, the support spring 3224 is in a deformed state, allowing the mounting frame 321 to be positioned within the support tube 31. The installer then pushes the mounting frame 321 to install the monitoring unit. The mounting bracket 321 moves axially upward along the support pipe 31. When the rotary fan is in the predetermined position, the rotary cylinder on the mounting bracket 321 starts to work. The moving rotary cylinder drives the limit strip to move, causing the limit strip to abut against the inner wall of the support pipe 31, thus fixing the position of the mounting bracket 321 and completing the preliminary installation work for the wastewater monitoring. After the installation of the monitoring unit 3 is completed, the urban wastewater is first stored in the storage tank 1. Then, chemicals or other disinfectants are added to the storage tank 1 to disinfect the wastewater. After standing for a period of time, the valve 5 starts to move, allowing the wastewater in the storage tank 1 to move along the connecting pipe 2, and then the flowing wastewater can move to the monitoring unit 3. When the wastewater... When the water flows to monitoring unit 3, the rotating fan blade 326, having a certain curvature, will start to rotate as water flows over it. This rotating fan blade 326 then drives the rotating frame 325 to rotate, which in turn drives the rotating shaft 324 to move. The rotating shaft 324 then drives the transmission assembly 327 to operate. As the rotating shaft 324 rotates, it drives the connected input shaft 3271 to rotate, which in turn drives the connected first rotating disk 3273 to move. When the first rotating disk 3273 rotates, it... The moving first connecting rods 32761 on the first rotating disk 3273 are driven to start moving. The moving first connecting rods 32761 can drive the second connecting rods 32762 to start rotating. The moving second connecting rods 32762 can drive the third connecting rods 32763 to start rotating. The moving third connecting rods 32763 can drive another first rotating disk 3273 connected to it to start moving, which in turn can drive the output shaft 3278 to start moving. When the output shaft 3278 starts moving, the moving output shaft 3278 can drive the rotating part connected to it to start moving. The counting unit can then record the number of rotations of the rotating part within a predetermined time and send the recorded number of rotations of the rotating part to the control device 33.When the control device 33 receives the signal from the counting unit, it can select the appropriate number of sampling devices based on the number of rotations to sample and detect the water flow into the outlet pipe 4. This not only allows for water flow monitoring but also enables the selection of the appropriate number of sampling devices based on the flow rate, thus avoiding increased costs for the enterprise.
