Description

Technical Field

[0001] The present disclosure relates to the technical field of sewage collection equipment, and more particularly to an anti-interference collection device for sewage detection in a sewage pipe network. Background Art

[0002] The sewage pipe network is composed of branch pipes, main pipes and trunk pipes, and is distributed in a dendritic shape. The sewage is transported to the treatment plant by gravity flow, and the inside of the pipe does not bear pressure. The auxiliary facilities include inspection wells for daily maintenance and monitoring.

[0003] When collecting sewage in the sewage pipe network for detection, it is necessary to insert the collection device from the inspection well into the main pipe or trunk pipe inside the pipe network to collect sewage. During the process of collecting samples, various factors may interfere, resulting in the collected samples not meeting the standards, thereby affecting the detection results. For example, during the detection process, the collection pipe touches the inner wall of the inspection well or the pipe, causing contamination; floating objects such as foam in the sewage pipe network block the nozzle of the collection pipe; problems such as sewage flow during the collection process and the collection bottle not being cleaned properly will all interfere with the collected samples, resulting in inaccurate detection results.

[0032] Embodiment

[0033] As Figures 1-5As shown, this embodiment provides an anti-interference collection device for sewage detection in a sewage pipe network, including a collection box 100, including a collection component; an anti-interference part 200, including a mounting shell 21, a push plate assembly 22, a lifting drive mechanism 23 and a rotating drive mechanism 24, the push plate assembly 22 is arranged at the bottom of the mounting shell 21 and is rotatably connected to the mounting shell 21, the mounting shell 21 includes a mounting cavity for accommodating the lifting drive mechanism 23 and the rotating drive mechanism 24, and the mounting shell 21 is connected to the collection box 100.

[0034] Among them, the input end of the collection component passes through the collection box 100 and extends to the push plate assembly 22. The lifting drive mechanism 23 drives the push plate assembly 22 to move closer or farther away from the preset center, so that the input end of the collection component is connected to or isolated from the outside world. The rotating drive mechanism 24 drives the push plate assembly 22 to rotate.

[0035] In this embodiment, the anti-interference part 200 is arranged at the bottom of the collection box 100, and the collection component in the collection box 100 includes an input end (i.e., a collection port for collecting sewage samples). The input end of the collection component passes through the collection box 100 and extends to the inner side of the push plate component 22, and is surrounded by the push plate component 22 to isolate it from the outside world and prevent it from being interfered with by the outside world, thereby affecting the collection effect; when the collection device goes deep into the sewage pipe network and contacts the sewage, the push plate component 22 is driven to separate by the lifting drive mechanism 23. During the separation process, the floating objects surrounding the input end of the collection component are pushed away to open the collection component, and after moving away, the push plate component 22 is driven to rotate by the rotating drive mechanism 24 to continuously block the floating objects from continuing to approach, thereby further ensuring that the collection port will not be blocked and contaminated by the floating objects during the collection process.

[0036] Specifically, the push plate assembly 22 includes a turntable 221, a plurality of push plates 222, a plurality of first connecting rods 223, a plurality of second connecting rods 224, and a hinge disc 225. In this embodiment, there are three push plates 222. The number of the first connecting rods 223 and the second connecting rods 224 is equal to that of the push plates 222 and corresponds one by one. The three push plates 222 are all triangular and are arranged in a circumferential array at the bottom of the turntable 221. When approaching, a conical enclosed space can be formed. A through hole is provided in the middle of the turntable 221, and a bushing 2211 is integrally formed on the through hole. The bushing 2211 is rotatably connected to the bottom of the mounting housing 21, so that the turntable 221 can rotate around the bushing 2211 as an axis, driving the push plates 222 to rotate. The push plates 222 are rotatably connected to the bottom of the turntable 221 through a first rotating shaft 2221. One end of the push plate 222 is rotatably connected to one end of the first connecting rod 223 through a second rotating shaft 2231. The other end of the first connecting rod 223 is rotatably connected to one end of the second connecting rod 224 through a third rotating shaft 2232. The middle of the first connecting rod 223 is rotatably connected to the hinge disc 225 through a fourth rotating shaft 2233. The end of the second connecting rod 224 away from the first connecting rod 223 is rotatably connected to the inner wall of the bushing 2211 through a fifth rotating shaft 2241. A drive tube 226 is fixedly connected to the middle of the turntable 221. The lifting drive mechanism 23 drives the drive tube 226 to lift. When the drive tube 226 rises, it drives the hinge disc 225 to rise, pulls the first connecting rod 223 to rotate around the fifth rotating shaft 2241, and pulls the push plate 222 to rotate around the first rotating shaft 2221. At this time, the bottom of the push plate 222 rotates inward and approaches each other, so that the input end of the acquisition component is wrapped and isolated from the outside, protecting the input end of the acquisition component from being polluted by the outside. When the drive tube 226 descends, it drives the hinge disc 225 to descend. At this time, the first connecting rod 223 rotates around the first rotating shaft, pushing the push plate 222 to rotate around the first rotating shaft 2221. At this time, the push plates 222 move away from each other, so that the input end of the acquisition component communicates with the outside, and at this time, the acquisition operation can be performed.

[0037] Specifically, the lifting drive assembly 23 includes a drive electric cylinder 231, a connecting member 232, a first bearing seat 233, and a first bearing 234. The first bearing 234 is embedded in the first bearing seat 233. The inner side of the first bearing 234 is fixed to the drive tube 226. The output shaft of the drive electric cylinder 231 is fixedly connected to one end of the connecting member 232, and the other end of the connecting member 232 is fixedly connected to the first bearing seat 233. The drive electric cylinder 231 drives the first bearing seat 233 to lift through the connecting member 232, thereby driving the drive tube 226 to lift. A first bearing 234 is provided between the drive tube 226 and the first bearing seat 233, enabling the drive tube 226 to rotate freely without causing the first bearing seat 233 and the connecting member 232 to rotate accordingly. When the rotary drive mechanism 24 drives the turntable 221 to rotate, the drive tube 226 will rotate synchronously. At this time, the rotation of the drive tube 226 will not affect the first bearing seat 233 and the connecting member 232, avoiding jamming.

[0038] Specifically, the rotary drive mechanism 24 includes a drive motor 241 and a drive gear 242. The output shaft of the drive motor 241 is key-connected to the drive gear 242. Teeth meshing with the drive gear 242 are provided on the outer side of the turntable 221. The drive gear 242 meshes with the turntable 221 through the teeth on the outer side of the turntable 221. The bushing 2211 is rotatably connected to the bottom of the mounting housing 21 through a second bearing 2212. The drive motor 241 drives the drive gear 242 to rotate, driving the turntable 221 to rotate with the second bearing 2212 as the support. The setting of the second bearing 2212 prevents the mounting housing 21 from rotating when the turntable 221 rotates, resulting in jamming. The rotation of the turntable 221 drives the push plate assembly 22 to rotate synchronously, enabling the push plate 222 to continuously push away the approaching floating objects, further protecting the collection assembly from interference and ensuring more accurate sewage samples are collected.

[0039] Specifically, the collection assembly includes a collection bottle 12 and a collection pump 11. The collection bottle 12 includes a water inlet 121. The input end of the collection pump 11 is connected to a collection pipe 13. The output end of the collection pump 11 is connected to the water inlet 121 through a pipeline. The end of the collection pipe 13 away from the collection pump 11 passes through the collection box 100, the mounting housing 21, and the drive shaft and extends to the inner side of a plurality of push plates 222, so that when the plurality of push plates 222 approach, they surround the collection pipe 13 to avoid external interference.

[0040] Further, a filter screen is provided at the end of the collection pipe 13 close to the push plate 222 to filter floating objects and prevent the inside of the collection pipe 13 from being blocked.

[0041] Further, the collection bottle 12 includes a water outlet 122, and a drain pipe 123 is connected to the water outlet 122. One end of the drain pipe 123 penetrates through the collection box 100 and extends to the outside of the collection box 100. An electronic valve 124 for controlling its on-off is provided on the drain pipe 123. Before collecting the sewage sample, there may be residual air and other factors interfering with the test results in the collection bottle 12. It is necessary to flush the inside of the collection bottle 12 with the sample multiple times to ensure that the collected sewage sample is more accurate. In this embodiment, the water inlet 121 is arranged at the bottom of the collection bottle 12, and the water outlet 122 is arranged at the upper part of the collection bottle 12. After the collection pump 11 pumps the sewage into the collection bottle 12 and fills the collection bottle 12, it is discharged from the water outlet 122. During actual collection, a time node can be set according to the pumping speed of the collection pump 11. Before the formal collection starts, the sewage samples collected before this time node will be discharged from the drain pipe 123. Then the electronic valve 124 controls the drain pipe 123 to close, and the collection pump 11 stops working. At this time, the sewage sample staying in the collection bottle 12 is the sample that finally needs to be tested, which can avoid the interference factors of the collection bottle 12 from affecting the test effect.

[0042] In another embodiment of the present application, the interior of the collection box 100 is separated into a collection chamber and an electric control chamber by a partition 101. The partition 101 is provided with a wire passing hole 1011. Among them, the collection assembly is arranged in the collection chamber, and a controller 31 and a power supply 32 are arranged in the electric control chamber. The controller 31 is connected to the collection assembly, the lifting drive mechanism 23 and the rotation drive mechanism 24 through internal wires to control their work. In this embodiment, the controller 31 and the power supply 32 are arranged in the collection box 100, eliminating the need for an external power supply 32 and wires to extend to the ground, thus avoiding damage to the wires.

[0043] Moreover, it further includes a flow rate sensor 4, and the flow rate sensor 4 is electrically connected to the controller 31. If the flow rate of the sewage in the sewage pipe network is too fast or unstable, the collected sewage sample is not accurate enough, which may interfere with the test results. By detecting the sewage flow rate with the flow rate sensor 4, when the detected water flow rate tends to be stable, the controller 31 receives the data detected by the flow rate sensor 4, and controls its instruction to make the lifting drive mechanism 23 control the push plate 222 to separate. Then the controller 31 instructs the rotation drive mechanism 24 to work, controlling the push plate 222 to rotate to block the continuously approaching floating objects. Finally, the controller 31 instructs the collection pump 11 to work to sample the sewage. In this way, the collection result is more accurate.

[0044] Further, it further includes an indicator light 5. The indicator light 5 is arranged at the top of the collection box 100, and the indicator light 5 is electrically connected to the controller 31. In this embodiment, after the flow rate sensor 4 comes into contact with the sewage, the controller 31 receives the signal from the flow rate sensor 4 and activates the indicator light 5. At this time, the indicator light 5 is constantly on. After the collection is completed, the indicator light 5 turns into a flashing state. At this time, the staff can take out the device to complete the sampling work.

[0045] Furthermore, a mounting member 6 is fixedly connected to the top of the collection box 100. The mounting member 6 is used to mount a suspension rope or a telescopic rod. The mounting member 6 can be a bolt sleeve or a lifting ring or other structures for connecting the telescopic rod or the suspension rope. The staff can put the device into the sewage pipe network through the telescopic rod or the suspension rope for sampling work.

[0046] The working principle of the present invention: The staff puts the device into the sewage pipe network through the suspension rope or the telescopic rod. During the descending process, the flow velocity sensor 4 penetrates into the sewage. After detecting the data, the controller 31 instructs the indicator light 5 to be constantly on. At this time, when the staff sees the indicator light 5 on, they can stop lowering the device. After the flow velocity sensor 4 detects that the sewage flow velocity tends to be stable, the controller 31 receives the signal and sends an instruction to the lifting drive mechanism 23. The driving electric cylinder 231 drives the connecting member 232 to move downward, driving the driving pipe 226 to descend, pushing the three push plates 222 away from each other, and pushing away the floating objects around the collection pipe 13. At the same time, the controller 31 instructs the rotation drive mechanism 24 to work. The driving motor 241 controls the driving gear 242 to rotate, driving the turntable 221 to rotate, thereby driving the three push plates 222 to rotate, continuously preventing the floating objects from approaching the collection pipe 13. Then, the collection pump 11 is started to collect sewage samples. At this time, the solenoid valve 124 is in an open state. After the sewage samples continuously flush the collection bottle 12 for a period of time, the solenoid valve 124 is closed. After the collection bottle 12 is filled, the collection pump 11 stops working. The controller 31 instructs the driving motor 241 to stop working. The driving plate drives the connecting member 232 to move upward to lift the driving pipe 226, pulling the push plates 222 closer to re-seal the collection pipe 13. Finally, the controller 31 instructs the indicator light 5 to change to a flashing state. After the staff sees the indicator light 5 flashing, they pull up the device to complete the sampling operation.

[0047] Before collection, the present invention uses the push plate assembly 22 in the anti-interference part 200 to wrap the collection end of the collection pipe 13, isolating it from the outside world, so that it will not be affected by external factors before collection. And before collection, the flow velocity sensor 4 is used to detect the sewage flow velocity, and the collection starts when the flow velocity tends to be stable. And during the collection process, the lifting drive mechanism 23 is used to drive the push plate assembly 22 to separate and push away the floating objects outside the collection assembly. Then, the rotation drive mechanism 24 is used to drive the push plate assembly 22 to rotate to further prevent the floating objects from approaching the input end of the collection assembly, making the entire collection process not affected by the floating objects. And during the collection process, the collection bottle 12 is continuously flushed to ensure the accuracy of the sample. Finally, after the device is taken out, the collection bottle 12 is sealed in the collection box 100 to avoid the influence of air and sunlight. Different interference factors are considered before, during and after collection to ensure the accuracy of the collected sample and the final test result.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure, rather than to limit them; although the present disclosure has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present disclosure.
