Description

Technical Field

[0001] The present application relates to the technical field of drainage network flow detection, and in particular to a drainage network flow monitoring device. Background Art

[0002] Flow detection of drainage pipe networks is a key measure to ensure the efficient operation of urban drainage systems, promptly detect and solve pipe blockages, leakages and illegal discharge problems, evaluate and optimize sewage treatment facilities, strengthen environmental protection and law enforcement, promote smart drainage and urban management, enhance the city's ability to cope with extreme weather, and predict and prevent potential problems. It is of great significance to safeguarding urban environmental quality and public health.

[0003] In the prior art, water level sensors and flow sensors are used to monitor the drainage network. The water level sensor is fixedly installed on the upper part of the drain pipe by bolts to monitor the water level in the drain pipe. The flow sensor is fixedly installed on the lower part of the drain pipe by bolts to monitor the water flow velocity in the drain pipe. The water flow in the drain pipe is obtained by combining the water level and the water flow velocity, thereby realizing real-time monitoring of the drainage network.

[0004] Regarding the above-mentioned related technologies, when there are plastic bags, leaves and other garbage in the drain pipe, they may cover the flow sensor and affect the normal use of the flow sensor. The sludge accumulated in the drain pipe and the grease, sludge and other impurities attached to the flow sensor may also cause inaccurate monitoring of the flow sensor. In addition, the installation and disassembly of the water level sensor and the flow sensor in the prior art are relatively troublesome, so improvements are made. Summary of the invention

[0005] In order to remove plastic bags, leaves and other garbage covering the flow sensor, reduce the impact of impurities such as grease and silt attached to the flow sensor and silt in the pipe on the monitoring of the flow sensor, and facilitate the installation and disassembly of the water level sensor and the flow sensor, the present application provides a drainage network flow monitoring device.

[0006] The present application provides a drainage network flow monitoring device, which adopts the following technical solution: A drainage pipe network flow monitoring device is installed between a first drainage pipe and a second drainage pipe, comprising a monitoring pipe body, both ends of which are respectively connected to the first drainage pipe and the second drainage pipe flanges, an equipment pipe is vertically arranged on the monitoring pipe body, the equipment pipe is communicated with the monitoring pipe body, a fixing plate is arranged at the end of the equipment pipe away from the monitoring pipe body, a telescopic pump is arranged in the equipment pipe, the fixed end of the telescopic pump is on the fixing plate, a lifting plate is arranged in the equipment pipe, the lifting plate is connected to the telescopic end of the telescopic pump, and a water level monitor is arranged on a surface of the lifting plate away from the fixing plate; The fixed plate is provided with an adjusting rod on one side close to the lifting plate, and the adjusting rod comprises a fixed tube and a lifting rod, and the lifting rod is rotatably and lifted in the fixed tube, and a sliding groove is provided on the inner wall of the fixed tube, and the sliding groove comprises a vertical linear groove and an arc linear groove, and the arc linear groove is provided above the vertical linear groove and is connected with the vertical linear groove, and a protrusion is provided on the outer peripheral wall of the lifting rod, and the protrusion is slidably arranged in the sliding groove, and a connecting block is provided on the end of the lifting rod away from the fixed rod, and the connecting block is rotatably connected with the lifting plate, and when the protrusion is located in the vertical linear groove, the connecting block is vertically lifted and lowered, and when the protrusion is located in the arc linear groove, the connecting block is rotatably lifted and lowered; A flow monitor is arranged in the monitoring tube body, and a mounting seat is arranged in the monitoring tube body, and the mounting seat is located directly below the lifting plate. A lifting assembly is arranged on the connecting block for lowering the flow monitor and mounting it on the mounting seat, and for lifting and removing the flow monitor from the mounting seat. A dredging mechanism is also arranged in the monitoring tube body for clearing silt at the bottom of the monitoring tube body.

[0007] By adopting the above technical solution, the monitoring pipe body is installed between the first drain pipe and the second drain pipe through the flange connection. The water level monitor in the monitoring pipe body can detect the water level in the monitoring pipe body, and the flow monitor can detect the water flow velocity in the monitoring pipe body. Since the flow monitor is generally installed at the inner lower part of the monitoring pipe body, plastic bags, leaves and other garbage in the water body may cover the flow monitor, thereby affecting the normal use of the flow monitor. Therefore, the telescopic pump is started, and the telescopic pump drives the lifting plate to descend. The descent of the lifting plate drives the lifting rod to descend until the connecting block descends to the lowest point, and then the telescopic end of the telescopic pump is shortened to drive the connecting block to start rising. At this time, the flow monitor is taken out from the mounting seat under the action of the lifting assembly. Since the connecting block is installed on the lifting rod, the protrusion on the lifting rod will first rise in the vertical linear groove, and there is no relative rotation between the lifting rod and the fixed tube. When the protrusion enters the arc-shaped linear groove, the lifting rod and the fixed tube will rotate relative to each other, thereby driving the flow monitor on the connecting block to rotate synchronously with the lifting rod. When the flow monitor rotates, under the action of gravity and water flow, plastic bags, leaves and other garbage covering the flow monitor are removed, and then the flow monitor is lowered and installed on the mounting seat through the lifting assembly through reverse operation, so as to realize the normal use of the flow monitor. A large amount of silt accumulated at the inner bottom of the monitoring tube body may cause inaccurate monitoring of the flow monitor. The dredging mechanism in the present application can remove the silt in the monitoring tube body, thereby improving the monitoring accuracy of the flow monitor. Optionally, the lifting assembly includes an electromagnet, a metal block and a quick installation and disassembly structure, the electromagnet is embedded in a surface of the connecting block away from the lifting rod, the metal block can be adsorbed on the electromagnet, the electromagnet can drive the metal block to descend, and install the metal block and the flow monitor on the mounting seat, and can drive the metal block to rise, and remove the metal block and the flow monitor from the mounting seat, and the quick installation and disassembly structure is used for quick installation and disassembly between the metal block and the flow monitor.

[0008] By adopting the above technical solution, the quick installation and disassembly structure can quickly install the flow monitor on the metal block, and quickly remove the flow monitor from the metal block, and the electromagnet can adsorb the metal block when powered on, and can be separated from the metal block when powered off, thereby driving the metal block to descend and installing the metal block and the flow monitor on the mounting seat, as well as driving the metal block to rise and remove the metal block and the flow monitor from the mounting seat, and keeping the metal block, the flow monitor and the connecting block in the same motion state, thereby realizing the lifting and rotation of the flow monitor.

[0009] Optionally, the quick installation and disassembly structure includes a clamping block, a reset piece and an unlocking block. The fixed end of the flow monitor is socketed on the metal block. There are two groups of clamping blocks. The two groups of clamping blocks are movably arranged in the metal block. The ends of the two groups of clamping blocks that are close to each other are wedge-shaped. The reset piece is arranged between the two groups of clamping blocks to bring the two groups of clamping blocks close to each other. A wedge-shaped clamping groove is provided at the fixed end of the flow monitor corresponding to the wedge-shaped ends of the two groups of clamping blocks. The unlocking block is arranged on the metal block to move the two groups of clamping blocks away from each other. The contact surfaces of the unlocking block and the two groups of clamping blocks are both wedge-shaped surfaces.

[0010] By adopting the above technical solution, the fixed end of the flow monitor is socketed and arranged on the metal block. Since the ends of the two groups of clamping blocks that are close to each other are wedge-shaped, when the flow monitor is installed, the end of the flow monitor will cause the two groups of clamping blocks to move away from each other until the wedge-shaped end of the clamping block is clamped and installed in the wedge-shaped clamping groove on the fixed end of the flow monitor. At this time, the flow monitor is quickly fixed on the metal block. When the flow monitor needs to be removed from the metal block, since the contact surfaces of the unlocking block and the two groups of clamping blocks are both wedge-shaped surfaces, pressing the unlocking block can make the two groups of clamping blocks move away from each other until the wedge-shaped end of the clamping block is separated from the wedge-shaped clamping groove on the fixed end of the flow monitor, and then the flow monitor can be removed from the metal block, thereby realizing rapid installation and disassembly of the flow monitor. Compared with the prior art, it is convenient to replace the flow monitor and realizes the fixed-point installation and disassembly of the flow monitor.

[0011] Optionally, the dredging mechanism includes a flap plate, a tooth plate, a driving gear, a rotating shaft and a driving assembly. A mounting groove is opened on the inner wall of the monitoring tube body. The tooth plate is slidably arranged in the mounting groove. The rotating shaft, the gear and the flap plate are provided in multiple groups. The multiple groups of rotating shafts are arranged at intervals on the side walls of the mounting groove. The multiple groups of driving gears and the flap plates are respectively arranged on the multiple groups of rotating shafts. The tooth plate and the driving gear are meshed with each other. The driving assembly is used to make the tooth plate reciprocate in the mounting groove.

[0012] By adopting the above technical solution, when the driving component drives the tooth plate to reciprocate in the installation groove, the tooth plate and the active gear are meshed with each other, so the active gear can be driven to rotate back and forth, so that the flap plate on the rotating shaft connected to the gear can be swung back and forth. When the flap plate swings back and forth, the silt in the monitoring tube body can be washed away by the water flow, thereby reducing the amount of silt in the monitoring tube body, thereby improving the monitoring accuracy of the flow monitor. When the water flow rate in the drainage network is slow, the removal effect of plastic bags, leaves and other garbage covering the flow monitor may be weak. Therefore, the water flow in the drainage network can be disturbed by the flap plate to cause waves, thereby improving the removal effect of plastic bags, leaves and other garbage covering the flow monitor.

[0013] Optionally, the drive assembly is provided with two groups, and the two groups of drive assemblies are respectively arranged at both ends of the monitoring tube, and the drive assembly includes a drive motor, a drive gear, a gear ring and a drive ring. The drive motor is arranged on the outer peripheral wall of the monitoring tube body, and the drive gear is arranged on the output shaft of the drive motor. The drive ring is rotatably arranged at one end inside the monitoring tube body, and the gear ring is placed on the drive ring, and the gear ring and the drive gear are meshed with each other. The end of the drive ring close to the equipment tube is arranged in a wavy shape, and the two ends of the gear plate are respectively abutted against the ends of the two groups of drive rings close to the equipment tube.

[0014] By adopting the above technical solution, the driving motor is started, and the driving gear on the output shaft of the driving motor drives the gear ring to rotate, thereby realizing the rotation of the driving ring connected to the gear ring. Since the end of the driving ring close to the equipment pipe is arranged in a wavy shape, and the two ends of the tooth plate are respectively abutted against the ends of the two groups of driving rings close to the equipment pipe, when the driving ring rotates, the shape of its end can make the tooth plate reciprocate in the installation groove, thereby driving the flip plate to swing back and forth.

[0015] Optionally, the mounting seat includes a first clamping block and a second clamping block, the first clamping block and the second clamping block are symmetrically arranged, and a moving block is arranged at the bottom, a mounting platform is arranged in the monitoring tube body, a moving groove is opened on the mounting platform, the moving block is slidably arranged in the moving groove, a spring is arranged in the moving groove, the spring is used to make the first clamping block and the second clamping block approach each other, and wedge-shaped guide blocks are arranged on the ends of the first clamping block and the second clamping block away from the moving block.

[0016] By adopting the above technical solution, when the electromagnet drives the metal block to move vertically downward, the metal block first contacts the wedge-shaped guide block. Under the action of the wedge-shaped guide block, the first clamping block and the second clamping block move away from each other. At this time, the spring is compressed until the metal block completely enters between the first clamping block and the second clamping block, thereby fixing the metal block on the mounting seat. The compressed spring can further improve the stability of the metal block on the mounting seat.

[0017] Optionally, a mounting plate is provided in the equipment tube, a wiping plate is provided on the mounting plate, the wiping plate is an arc-shaped plate, a sponge layer is provided on the wiping plate for wiping the monitoring end of the flow monitor, and an arc avoidance groove is provided on the lifting plate corresponding to the wiping plate.

[0018] By adopting the above technical scheme, the telescopic section of the telescopic pump is shortened, and the lifting plate rises to make the wiper plate extend through the arc avoidance groove. At the same time, the electromagnet on the connecting block drives the metal block to rotate and rise. When the flow monitor rotates and rises, it abuts against the wiper plate, so that the sponge layer on the wiper plate wipes the monitoring end of the flow monitor, thereby further improving the monitoring accuracy of the flow monitor, and while wiping, the more stubborn plastic bags, leaves and other garbage attached to the flow monitor can be removed.

[0019] Optionally, an opening and closing window is provided on the equipment pipe to facilitate replacement of the water level monitor and the flow monitor.

[0020] By adopting the above technical solution, when the water level monitor and the flow monitor rise to the highest point, the opening and closing window can be opened to quickly replace the water level monitor and the flow monitor. Compared with the existing technology, there is no need to throttle the drainage network during maintenance and replacement, which improves the efficiency of maintenance and replacement and avoids the impact of maintenance and replacement on the drainage network.

[0021] In summary, the present application includes at least one of the following beneficial technical effects: 1. Since the flow monitor is generally installed at the lower inner part of the monitoring tube body, plastic bags, leaves and other garbage in the water body may be wrapped around the flow monitor, thus affecting the normal use of the flow monitor. Therefore, the telescopic pump is started, and the telescopic pump drives the lifting plate to descend. The descent of the lifting plate drives the lifting rod to descend until the connecting block descends to the lowest point, and then the telescopic end of the telescopic pump is shortened to drive the connecting block to start rising. At this time, the flow monitor is taken out from the mounting seat under the action of the lifting assembly. Since the connecting block is installed on the lifting rod, the protrusion on the lifting rod will first rise in the vertical linear groove, and there is no relative rotation between the lifting rod and the fixed pipe. When the protrusion enters the arc-shaped linear groove, the lifting rod and the fixed pipe rotate relative to each other, thereby driving the flow monitor on the connecting block to rotate synchronously with the lifting rod. When the flow monitor rotates, under the action of gravity and water flow, the plastic bags, leaves and other garbage wrapped around the flow monitor are removed, and then the flow monitor is lowered and installed on the mounting seat through the lifting assembly through the reverse operation, so as to realize the normal use of the flow monitor. 2. When the water level monitor and flow monitor rise to the highest point, the opening and closing window can be opened to quickly install and disassemble the water level monitor and flow monitor. Compared with the existing technology, there is no need to perform throttling operations on the drainage network during maintenance and replacement, which improves the efficiency of maintenance and replacement and avoids the impact of maintenance and replacement on the drainage network; 3. When the driving component drives the tooth plate to reciprocate in the installation groove, the tooth plate and the driving gear are meshed with each other, so the driving gear can be driven to reciprocate, so the flap plate on the rotating shaft connected to the gear can be reciprocated. When the flap plate reciprocates, the silt in the monitoring pipe body can be washed away by water flow, thereby reducing the amount of silt in the monitoring pipe body, thereby improving the monitoring accuracy of the flow monitor. When the water flow rate in the drainage network is slow, the removal effect of plastic bags, leaves and other garbage wrapped on the flow monitor may be weak. Therefore, the water flow in the drainage network can be disturbed by the flap plate to make it wave, thereby improving the removal effect of plastic bags, leaves and other garbage wrapped on the flow monitor; 4. The telescopic section of the telescopic pump is shortened, and the lifting plate rises to make the wiper plate extend through the arc avoidance groove. At the same time, the electromagnet on the connecting block drives the metal block to rotate and rise. When the flow monitor rotates and rises, it abuts against the wiper plate, so that the sponge layer on the wiper plate wipes the monitoring end of the flow monitor, thereby further improving the monitoring accuracy of the flow monitor. At the same time, the more stubborn plastic bags, leaves and other garbage attached to the flow monitor can be removed. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The following is combined with Figure 1-6 This application is described in further detail.

[0026] The present application discloses a drainage network flow monitoring device, referring to Figure 1 , Figure 2 and Figure 3A drainage pipe network flow monitoring device is installed between a first drainage pipe and a second drainage pipe, and includes a monitoring pipe body 1. The two ends of the monitoring pipe body 1 are respectively connected to the first drainage pipe and the second drainage pipe flanges. An equipment pipe 11 is vertically arranged on the monitoring pipe body 1. The equipment pipe 11 is connected to the monitoring pipe body 1. A fixing plate 12 is arranged at the end of the equipment pipe 11 away from the monitoring pipe body 1. A telescopic pump 13 is arranged in the equipment pipe 11. The fixed end of the telescopic pump 13 is arranged on the fixing plate 12. A lifting plate 14 is arranged in the equipment pipe 11. The lifting plate 14 is connected to the telescopic end of the telescopic pump 13. A water level monitor 15 is arranged on the side of the lifting plate 14 away from the fixing plate 12.

[0027] The fixed plate 12 is provided with an adjustment rod 16 on one side close to the lifting plate 14. The adjustment rod 16 includes a fixed tube 161 and a lifting rod 162. The lifting rod 162 is rotatably lifted and lowered in the fixed tube 161. A sliding groove is provided on the inner wall of the fixed tube 161. The sliding groove includes a vertical groove 163 and an arc groove 164. The arc groove 164 is provided above the vertical groove 163 and communicates with the vertical groove 163. A convex block is provided on the outer peripheral wall of the lifting rod 162. The convex block is slidably provided in the sliding groove. A connecting block 17 is provided on the end of 162 away from the fixed rod, and the connecting block 17 is rotatably connected to the lifting plate 14. When the protrusion is located in the vertical linear groove 163, the connecting block 17 is vertically lifted and lowered, and when the protrusion is located in the arc-shaped linear groove 164, the connecting block 17 is rotationally lifted and lowered; a flow monitor 18 is provided in the monitoring tube body 1, and a mounting seat 2 is provided in the monitoring tube body 1. The mounting seat 2 is located directly below the lifting plate 14, and a lifting assembly 3 is provided on the connecting block 17; a dredging mechanism 4 is also provided in the monitoring tube body 1.

[0028] The monitoring pipe body 1 is installed between the first drain pipe and the second drain pipe through a flange connection. The water level monitor 15 in the monitoring pipe body 1 can detect the water level in the monitoring pipe body 1, and the flow monitor 18 can detect the water flow velocity in the monitoring pipe body 1. Since the flow monitor 18 is generally installed at the inner lower part of the monitoring pipe body 1, plastic bags, leaves and other garbage in the water body may be covered on the flow monitor 18, thereby affecting the normal use of the flow monitor 18. Therefore, the telescopic pump 13 is started, and the telescopic pump 13 drives the lifting plate 14 to descend. The descent of the lifting plate 14 drives the lifting rod 162 to descend until the connecting block 17 descends to the lowest point, and then the telescopic end of the telescopic pump 13 is shortened to drive the connecting block 17 to start rising. At this time, under the action of the lifting component 3, The flow monitor 18 is taken out from the mounting seat 2. Since the connection block 17 is mounted on the lifting rod 162, the protrusion on the lifting rod 162 will first rise in the vertical linear groove 163, and there will be no relative rotation between the lifting rod 162 and the fixed tube 161. When the protrusion enters the arc-shaped linear groove 164, the lifting rod 162 and the fixed tube 161 will rotate relative to each other, thereby driving the flow monitor 18 on the connection block 17 to rotate synchronously with the lifting rod 162. When the flow monitor 18 rotates, under the action of gravity and water flow, the plastic bags, leaves and other garbage wrapped on the flow monitor 18 are removed, and then the flow monitor 18 is lowered and installed on the mounting seat 2 through the lifting component 3 by reverse operation, so as to realize the normal use of the flow monitor 18. A large amount of silt accumulated at the inner bottom of the monitoring tube body 1 may cause inaccurate monitoring of the flow monitor 18. The silt removal mechanism 4 in the present application can remove the silt in the monitoring tube body 1, thereby improving the monitoring accuracy of the flow monitor 18.

[0029] Reference Figure 2 and Figure 3 The lifting assembly 3 includes an electromagnet 31, a metal block 32 and a quick installation and removal structure 33. The electromagnet 31 is embedded in the side of the connecting block 17 away from the lifting rod 162. The metal block 32 can be adsorbed on the electromagnet 31. The electromagnet 31 can drive the metal block 32 to descend and install the metal block 32 and the flow monitor 18 on the mounting seat 2, and can drive the metal block 32 to rise and remove the metal block 32 and the flow monitor 18 from the mounting seat 2. The quick installation and removal structure 33 is used for quick installation and removal between the metal block 32 and the flow monitor 18.

[0030] The quick installation and removal structure 33 can quickly install the flow monitor 18 on the metal block 32, and quickly remove the flow monitor 18 from the metal block 32, and the electromagnet 31 can adsorb the metal block 32 when powered on, and can be separated from the metal block 32 when powered off, thereby driving the metal block 32 to descend and install the metal block 32 and the flow monitor 18 on the mounting base 2, as well as driving the metal block 32 to rise and remove the metal block 32 and the flow monitor 18 from the mounting base 2, and keeping the metal block 32, the flow monitor 18 and the connecting block 17 in the same motion state, thereby realizing the lifting and rotation of the flow monitor 18.

[0031] Reference Figure 5 The quick installation and disassembly structure 33 includes a clamping block 331, a reset member 332 and an unlocking block 333. The fixed end of the flow monitor 18 is socketed and arranged on the metal block 32. The clamping block 331 is provided with two groups. The two groups of clamping blocks 331 are movably arranged in the metal block 32. The ends of the two groups of clamping blocks 331 close to each other are wedge-shaped. The reset member 332 is arranged between the two groups of clamping blocks 331, and is used to make the two groups of clamping blocks 331 close to each other. A wedge-shaped clamping groove is opened at the fixed end of the flow monitor 18 corresponding to the wedge-shaped ends of the two groups of clamping blocks 331. The unlocking block 333 is arranged on the metal block 32, and is used to make the two groups of clamping blocks 331 move away from each other. The contact surfaces of the unlocking block 333 and the two groups of clamping blocks 331 are both wedge-shaped surfaces. In this embodiment, the reset member 332 is a spring, which is a preferred embodiment of this embodiment. In other embodiments, the reset member 332 can be an elastic connecting block, etc.

[0032] The fixed end of the flow monitor 18 is inserted and arranged on the metal block 32. Since the ends of the two sets of clamping blocks 331 close to each other are wedge-shaped, when the flow monitor 18 is installed, the end of the flow monitor 18 will make the two sets of clamping blocks 331 move away from each other until the wedge-shaped ends of the clamping blocks 331 are clamped and installed in the wedge-shaped clamping groove on the fixed end of the flow monitor 18. At this time, the flow monitor 18 is quickly fixed and installed on the metal block 32. When the flow monitor 18 needs to be removed from the metal block 32, When the block 32 is removed, since the contact surfaces of the unlocking block 333 and the two groups of clamping blocks 331 are wedge-shaped surfaces, pressing the unlocking block 333 can make the two groups of clamping blocks 331 move away from each other until the wedge-shaped end of the clamping block 331 is separated from the wedge-shaped clamping groove on the fixed end of the flow monitor 18, and then the flow monitor 18 can be removed from the metal block 32, thereby realizing rapid installation and disassembly of the flow monitor 18, which is convenient for replacing the flow monitor 18 compared with the prior art.

[0033] Reference Figure 4 and Figure 6The dredging mechanism 4 includes a flip plate 41, a tooth plate 42, a driving gear 43, a rotating shaft 44 and a driving assembly 46. A mounting groove 45 is opened on the inner wall of the monitoring tube body 1. The tooth plate 42 is slidably arranged in the mounting groove 45. There are multiple groups of rotating shafts 44, gears and flip plates 41. The multiple groups of rotating shafts 44 are arranged at intervals on the side walls of the mounting groove 45. The multiple groups of driving gears 43 and the flip plates 41 are respectively arranged on the multiple groups of rotating shafts 44. The tooth plate 42 and the driving gear 43 are meshed with each other. The driving assembly 46 is used to make the tooth plate 42 reciprocate in the mounting groove 45.

[0034] When the driving component 46 drives the tooth plate 42 to reciprocate in the installation groove 45, the tooth plate 42 and the driving gear 43 are meshed with each other, so the driving gear 43 can be driven to rotate reciprocatingly, so that the flip plate 41 on the rotating shaft 44 connected to the gear can be swung back and forth. When the flip plate 41 swings back and forth, the silt in the monitoring pipe body 1 can be washed away by the water flow, thereby reducing the amount of silt in the monitoring pipe body 1, thereby improving the monitoring accuracy of the flow monitor 18. When the water flow rate in the drainage network is slow, the removal effect of plastic bags, leaves and other garbage wrapped on the flow monitor 18 may be weak. Therefore, the water flow in the drainage network can be disturbed by the flip plate 41 to cause waves, thereby improving the removal effect of plastic bags, leaves and other garbage wrapped on the flow monitor 18.

[0035] Reference Figure 3 and Figure 4 There are two groups of drive components 46, and the two groups of drive components 46 are respectively arranged at both ends of the monitoring tube. The drive components 46 include a drive motor 461, a drive gear 462, a gear ring 463 and a drive ring 464. The drive motor 461 is arranged on the outer peripheral wall of the monitoring tube body 1, and the drive gear 462 is arranged on the output shaft of the drive motor 461. The drive ring 464 is rotatably arranged at one end inside the monitoring tube body 1. The gear ring 463 is sleeved on the drive ring 464, and the gear ring 463 and the drive gear 462 are meshed with each other. The end of the drive ring 464 close to the equipment pipe 11 is arranged in a wavy shape, and the two ends of the tooth plate 42 are respectively abutted against the ends of the two groups of drive rings 464 close to the equipment pipe 11.

[0036] The driving motor 461 is started, and the driving gear 462 on the output shaft of the driving motor 461 drives the gear ring 463 to rotate, thereby realizing the rotation of the driving ring 464 connected to the gear ring 463. Since the end of the driving ring 464 close to the equipment pipe 11 is arranged in a wave shape, and the two ends of the tooth plate 42 are respectively abutted against the ends of the two groups of driving rings 464 close to the equipment pipe 11, when the driving ring 464 rotates, the shape of its end can make the tooth plate 42 reciprocate in the mounting groove 45, thereby driving the flip plate 41 to swing back and forth.

[0037] Reference Figure 6 The mounting seat 2 includes a first clamping block 21 and a second clamping block 22, the first clamping block 21 and the second clamping block 22 are symmetrically arranged, and a moving block 23 is arranged at the bottom. A mounting platform is arranged in the monitoring tube body 1, and a moving groove is opened on the mounting platform. The moving block 23 is slidably arranged in the moving groove, and a spring 24 is arranged in the moving groove. The spring 24 is used to make the first clamping block 21 and the second clamping block 22 approach each other. Wedge-shaped guide blocks 25 are arranged on the ends of the first clamping block 21 and the second clamping block 22 away from the moving block 23.

[0038] When the electromagnet 31 drives the metal block 32 to move vertically downward, the metal block 32 first contacts the wedge-shaped guide block 25. Under the action of the wedge-shaped guide block 25, the first clamping block 21 and the second clamping block 22 are moved away from each other. At this time, the spring 24 is compressed until the metal block 32 completely enters between the first clamping block 21 and the second clamping block 22, thereby fixing the metal block 32 on the mounting seat 2. The compressed spring 24 can further improve the stability of the metal block 32 on the mounting seat 2.

[0039] Reference Figure 2 and Figure 3 , a mounting plate 5 is arranged in the equipment pipe 11, and a wiping plate 51 is arranged on the mounting plate 5. The wiping plate 51 is an arc-shaped plate, and a sponge layer for wiping the monitoring end of the flow monitor 18 is arranged on the wiping plate 51. An arc avoidance groove is opened on the lifting plate 14 corresponding to the wiping plate 51. The telescopic section of the telescopic pump 13 is shortened, and the lifting plate 14 rises to make the wiping plate 51 extend through the arc avoidance groove. At the same time, the electromagnet 31 on the connecting block 17 drives the metal block 32 to rotate and rise. When the flow monitor 18 rotates and rises, it abuts against the wiping plate 51, so that the sponge layer on the wiping plate 51 wipes the monitoring end of the flow monitor 18, thereby further improving the monitoring accuracy of the flow monitor 18, and while wiping, the more stubborn garbage such as plastic bags and leaves attached to the flow monitor 18 can be removed.

[0040] The equipment pipe 11 is provided with an opening and closing window 6 for facilitating the replacement of the water level monitor 15 and the flow monitor 18. When the water level monitor 15 and the flow monitor 18 rise to the highest point, the opening and closing window 6 can be opened to quickly replace the water level monitor 15 and the flow monitor 18. Compared with the prior art, there is no need to throttle the drainage network during maintenance and replacement, which improves the efficiency of maintenance and replacement and avoids the impact of maintenance and replacement on the drainage network.

[0041] The implementation principle of a drainage network flow monitoring device in the embodiment of the present application is: When it is necessary to remove the garbage coated on the flow monitor 18, the telescopic pump 13 drives the lifting plate 14 to descend, and the descent of the lifting plate 14 drives the lifting rod 162 to descend until the connecting block 17 descends to the lowest point so that the electromagnet 31 abuts against the metal block 32, and the electromagnet 31 is started, and then the telescopic end of the telescopic pump 13 is shortened to drive the connecting block 17 to start rising. At this time, the flow monitor 18 is taken out from the mounting seat 2 under the electromagnet 31 and the metal block 32. Since the connecting block 17 is installed on the lifting rod 162, the protrusion on the lifting rod 162 will first rise in the vertical linear groove 163, and then the lifting rod 162 will rise. There is no relative rotation between the lowering rod 162 and the fixed tube 161. When the protrusion enters the arc-shaped groove 164, the lifting rod 162 and the fixed tube 161 rotate relative to each other, thereby driving the flow monitor 18 on the connecting block 17 to rotate synchronously with the lifting rod 162. When the flow monitor 18 rotates, under the action of gravity and water flow, plastic bags, leaves and other garbage covering the flow monitor 18 are removed, and then the flow monitor 18 is lowered and installed on the mounting seat 2 through the lifting component 3 by reverse operation, so as to realize the normal use of the flow monitor 18.

[0042] When it is necessary to remove the sludge in the monitoring tube body 1, the driving motor 461 is started, and the driving gear 462 on the output shaft of the driving motor 461 drives the gear ring 463 to rotate, thereby realizing the rotation of the driving ring 464 connected to the gear ring 463. Since the end of the driving ring 464 close to the equipment pipe 11 is arranged in a wavy shape, and the two ends of the tooth plate 42 are respectively abutted against the ends of the two groups of driving rings 464 close to the equipment pipe 11, when the driving ring 464 rotates, the tooth plate 42 can be reciprocated in the mounting groove 45 through the shape of its end. Since the tooth plate 42 and the driving gear 43 are meshed with each other, the driving gear 43 can be driven to reciprocate, so that the flip plate 41 on the rotating shaft 44 connected to the gear can be reciprocated. When the flip plate 41 reciprocates, the water flow can be used to wash away the sludge in the monitoring tube body 1, thereby reducing the amount of sludge in the monitoring tube body 1, thereby improving the monitoring accuracy of the flow monitor 18.
