Description

[0001] This is a divisional application. The invention name of the original application is: A monitoring device and monitoring system for intelligently monitoring the situation of rain and sewage underground pipelines. The application date of the original application is: July 13, 2022, and the application number of the original application is: 202210824149.6. Technical Field

[0002] The present invention relates to the technical field of pipeline monitoring, and particularly relates to a monitoring system for intelligently monitoring the situation of rain and sewage underground pipelines. Background Art

[0003] Generally, rural sewage projects belong to the county-wide governance, but the governance scope is mostly scattered, small and miscellaneous, causing a lot of economic and human pressure on the existing operation and maintenance teams. Under the restriction of the untimely information feedback of the existing operation and maintenance teams, the infrastructure of a certain rural sewage project is severely damaged and can no longer meet the requirements of normal domestic sewage treatment. For pipeline monitoring, it is currently common to manually check whether the pipe network is damaged. This monitoring method is not conducive to large-area operation and maintenance, and at the same time, it is difficult to unify the manual judgment criteria, bringing data chaos to the monitoring process.

[0004] How to solve the above technical problems is the subject faced by the present invention. Summary of the Invention

[0005] In order to solve the problems in the above-mentioned prior art, the present invention provides a monitoring device for intelligently monitoring the situation of rain and sewage underground pipelines, which has a simple structure, ingenious design, real-time monitoring and low operation and maintenance costs, and a monitoring system with effective monitoring, high supervision efficiency, reduced operation and maintenance costs of treatment facilities, and high reliability of monitoring data.

[0006] To achieve the above invention purpose, the present invention provides a monitoring device for intelligently monitoring the situation of rain and sewage underground pipelines, which includes a hollow column-shaped slide rail arranged on the top wall of the pipeline and communicating with the pipeline at the bottom end, a reflection-absorbing infrared hollow column with the top end cooperating with the hollow column-shaped slide rail and a high-transparency hollow floating body arranged at the bottom end, a long-wave infrared emission strip and a second long-wave infrared receiving strip which are vertically arranged on one inner wall of the pipeline and respectively cooperate with the reflection-absorbing infrared hollow column, and a first long-wave infrared receiving strip arranged on the opposite inner wall of the pipeline and cooperating with the long-wave infrared emission strip. The long-wave infrared emission strip, the first long-wave infrared receiving strip, and the second long-wave infrared receiving strip are at the same height and flush.

[0007] The highly transparent hollow floating body serves to support and lift the infrared-reflecting and -absorbing hollow column, keeping the bottom of the infrared-reflecting and -absorbing hollow column always flush with the water surface. Meanwhile, it does not block the passage of long-wave infrared rays through the water layer. The principle of keeping the bottom of the infrared-reflecting and -absorbing hollow column always flush with the water surface is as follows: gravitational force mg = buoyant force ρgv. The flowing substance in the pipeline is relatively stable, and the density ρ is known. That is, the mass m of the infrared-reflecting and -absorbing hollow column and the highly transparent hollow floating body is proportional to the drainage volume v of the highly transparent hollow floating body. Thus, the critical volume for keeping the bottom of the infrared-reflecting and -absorbing hollow column always flush with the water surface can be calculated. The critical volume will not be elaborated here. In actual production, a proportional calculation is carried out. When the infrared-reflecting and -absorbing hollow column rises and falls with the change in the water layer height, the bottom of the infrared-reflecting and -absorbing hollow column can always be kept flush with the water surface.

[0008] During use, when rain and sewage flow through the pipeline, an air layer and a water layer are formed from top to bottom inside the pipeline. The highly transparent hollow floating body floats at the junction of the water layer and the air layer, rising and falling with the change in the water layer height, driving the infrared-reflecting and -absorbing hollow column to slide along the hollow column body slide rail. Furthermore, the material of the highly transparent hollow floating body is set as ultra-thin resin. The long-wave infrared rays emitted by the long-wave infrared emission strip are divided into two parts: The part located in the water layer is received by the first long-wave infrared receiving strip through the water layer or the highly transparent hollow floating body. That is, the height at which the first long-wave infrared receiving strip receives the long-wave infrared rays is a. The part located in the air layer is received by the second long-wave infrared receiving strip after being reflected by the infrared-reflecting and -absorbing hollow column. That is, the height at which the second long-wave infrared receiving strip receives the long-wave infrared rays is b. The preset height of the long-wave infrared emission strip is c. When c = a + b, the pipeline operates normally; when c ≠ a + b, the pipeline operates abnormally. At this time, sludge may accumulate at the bottom of the water layer, and the sum of the height of the accumulation, height a, and height b is equal to height c.

[0009] Another specific feature of the present invention is that the cross-sectional shape of the pipeline is set as a rectangle with a horizontal bottom surface. The height of the long-wave infrared emission strip is equal to the height of the pipeline side wall. The long-wave infrared emission strip, the first long-wave infrared receiving strip, and the second long-wave infrared receiving strip are arranged on the pipeline side wall from bottom to top. That is, the height of the pipeline side wall is c, the height of the water layer is a, and the height of the air layer is b. When the pipeline operates normally, the height of the pipeline side wall is the sum of the height of the water layer and the height of the air layer, which is convenient for monitoring.

[0010] Specific features of the present invention further include that the emitting end of the long-wave infrared emitting strip is set as a converging type, and the converging opening performs infrared filtering to make the emitted long-wave infrared rays parallel to the cross-section of the pipeline, reducing the diffuse reflection of the long-wave infrared rays and improving the effectiveness of the measurement results. The receiving ends of the first long-wave infrared receiving strip and the second long-wave infrared receiving strip are set as a diverging type, and the diverging opening performs long-wave infrared ray reception to receive as much as possible the long-wave infrared rays that are not parallel to the cross-section of the pipeline due to diffuse reflection, improving the effectiveness of the measurement results, and ensuring that the long-wave infrared rays emitted by the long-wave infrared emitting strip are received by the first long-wave infrared receiving strip and / or the second long-wave infrared receiving strip.

[0011] Specific features of the present invention further include that the reflection-absorbing infrared hollow column includes a hollow column body and carbon dioxide gas filled in the hollow column body. The side wall of the hollow column body close to the long-wave infrared emitting strip is made of quartz glass or the outer side wall is fully pasted with quartz glass. Since long-wave infrared rays are difficult to penetrate quartz glass, the long-wave infrared rays emitted by the long-wave infrared emitting strip are reflected when encountering the quartz glass, and after entering the hollow column body through diffuse reflection, they are absorbed by the filled carbon dioxide gas.

[0012] Specific features of the present invention further include that a first infrared-reflecting coating is provided on the outer side surface of the quartz glass to further reflect the long-wave infrared rays emitted by the long-wave infrared emitting strip. A second infrared-reflecting coating is provided on the inner side surface of the side wall of the hollow column body opposite to the quartz glass to reflect the long-wave infrared rays entering the hollow column body and prevent them from passing through the hollow column body and being received by the first long-wave infrared receiving strip, ensuring the effectiveness of the monitoring. Preferably, the materials of the first infrared-reflecting coating and the second infrared-reflecting coating are set as a combination of vacuum infrared coating and metal coating to ensure a high reflectivity of long-wave infrared rays.

[0013] Furthermore, except for the side surface provided with quartz glass of the hollow column body, the remaining side surfaces are all made of high-transparency thin-wall resin or the outer side wall is fully pasted with high-transparency thin-wall resin. Using the principle that long-wave infrared rays can penetrate resin, the long-wave infrared rays with diffuse reflection in the water layer enter the reflection-absorbing infrared hollow column and are absorbed by the filled carbon dioxide gas. Preferably, the high-transparency thin-wall resin is set as hard resin.

[0014] Furthermore, a non-damping pulley is installed on the inner wall of the slide rail of the hollow column body to ensure that there is no obstruction when the reflection-absorbing infrared hollow column makes a reciprocating motion inside it. Preferably, the slide rail of the hollow column body is integrally injection-molded with the pipeline.

The monitoring device for intelligently monitoring the situation of the rainwater and sewage underground pipeline is installed on the measuring pipe section. Preferably, the material of the pipeline is set to fiberglass reinforced plastic with a smooth inner wall, and the inner wall of the pipeline is coated with an antibacterial and anti-fouling bonding material coating; further, a pipeline socket is provided at the output end of the outlet pipe section, and a pipeline spigot matching the pipeline socket is provided at the input end of the inlet pipe section.

[0016] The laminar flow and stable flow grit chamber section and the inlet pipe section are completed by integral injection molding.

A waistline is formed in the middle when the water storage pipe section transitions from the measuring pipe section to the outlet pipe section, and the bottom wall of the water storage pipe section close to the outlet pipe section is raised upward, and both side walls are inwardly converging.

[0017] Specific features of the present invention further include that a sinking part is provided in the laminar flow steady flow grit chamber section, and the bottom wall of the sinking part is lower than the bottom wall of the measuring pipe section. When rainwater and sewage flow through this place, the water flow is slowed down to form a laminar steady state, and at the same time, sediment and other pollutants are precipitated in the sinking part, making the measurement data of the measuring pipe section by the monitoring device for intelligently monitoring the underground pipeline situation of rainwater and sewage more accurate. Further, the cross-sectional shape of the output end of the water inlet pipe section is set to be circular, the shape of the input end of the measuring pipe section is set to be rectangular, and the cross-section of the output end of the water inlet pipe section is larger than the cross-section of the input end of the measuring pipe section.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] To clearly illustrate the technical features of this solution, the following elaborates on this solution through specific embodiments.

[0025] Embodiment 1 See Figures 1 to 6, an embodiment of the present invention provides a monitoring device for intelligently monitoring the situation of rain and sewage underground pipelines. Among them, it includes a hollow cylindrical slide rail 7 arranged on the top wall of the pipeline and communicating with the pipeline at the bottom end, a reflection-absorbing infrared hollow column 5 with the top end cooperating with the hollow cylindrical slide rail 7 and a high-transparency hollow floating body 8 arranged at the bottom end, a long-wave infrared emission strip 3 and a second long-wave infrared receiving strip 6 vertically arranged on one inner wall of the pipeline and respectively cooperating with the reflection-absorbing infrared hollow column 5, and a first long-wave infrared receiving strip 4 arranged on the opposite inner wall of the pipeline and cooperating with the long-wave infrared emission strip 3. The long-wave infrared emission strip 3, the first long-wave infrared receiving strip 4, and the second long-wave infrared receiving strip 6 are at the same height and flush.

[0026] The high-transparency hollow floating body 8 serves to support the reflection-absorbing infrared hollow column 5 and keeps the bottom of the reflection-absorbing infrared hollow column 5 always flush with the water surface. At the same time, it does not block the long-wave infrared rays 14 from passing through the water layer 31. The principle of keeping the bottom of the reflection-absorbing infrared hollow column 5 always flush with the water surface is: gravitational force mg = buoyant force ρgv. The flowing substance in the pipeline is relatively stable, and the density ρ is known. That is, the mass m of the reflection-absorbing infrared hollow column 5 and the high-transparency hollow floating body 8 is proportional to the drainage volume v of the high-transparency hollow floating body 8. The critical volume for keeping the bottom of the reflection-absorbing infrared hollow column 5 always flush with the water surface can be calculated. The critical volume is not elaborated here and is calculated proportionally in actual production. When the reflection-absorbing infrared hollow column 5 fluctuates up and down with the change of the water layer height, the bottom of the reflection-absorbing infrared hollow column 5 can always be flush with the water surface.

[0027] When in use, when rain and sewage flow through the pipeline, an air layer 30 and a water layer 31 are formed from top to bottom in the pipeline. The high-transparency hollow floating body 8 floats at the junction of the water layer 31 and the air layer 30 and fluctuates up and down with the change of the water layer 31 height, driving the reflection-absorbing infrared hollow column 5 to slide along the hollow cylindrical slide rail 7; Further, the material of the high-transparency hollow floating body 8 is set as ultra-thin resin. The long-wave infrared rays 14 emitted by the long-wave infrared emission strip 3 are divided into two parts: The part located in the water layer 31 is received by the first long-wave infrared receiving strip 4 through the water layer or the high-transparency hollow floating body 8. That is, the height at which the first long-wave infrared receiving strip 4 receives the long-wave infrared rays 14 is a; The part located in the air layer 30 is reflected by the reflection-absorbing infrared hollow column 5 and then received by the second long-wave infrared receiving strip 6. That is, the height at which the second long-wave infrared receiving strip 6 receives the long-wave infrared rays 14 is b; The preset height of the long-wave infrared emission strip 3 is c. When c = a + b, the pipeline operates normally; when c ≠ a + b, the pipeline operates abnormally. At this time, sludge may accumulate at the bottom of the water layer 31, and the sum of the height of the accumulation, height a, and height b is equal to height c.

[0028] Another specific feature of the present invention is that the cross-sectional shape of the pipeline is set as a rectangle with a horizontal bottom surface. The height of the long-wave infrared emission strip 3 is equal to the height of the pipeline side wall. The long-wave infrared emission strip 3, the first long-wave infrared reception strip 4, and the second long-wave infrared reception strip 6 are arranged on the pipeline side wall from bottom to top. That is, the height of the pipeline side wall is c, the height of the water layer 31 is a, and the height of the air layer 30 is b. When the pipeline operates normally, the height of the pipeline side wall is the sum of the height of the water layer 31 and the height of the air layer 30, which is convenient for monitoring.

[0029] Another specific feature of the present invention is that the emission end of the long-wave infrared emission strip 3 is set as a converging type. The converging type is provided with an infrared filter at the opening to make the emitted long-wave infrared rays 14 parallel to the cross-section of the pipeline, reducing the diffuse reflection of the long-wave infrared rays 14 and improving the effectiveness of the measurement results. The receiving ends of the first long-wave infrared reception strip 4 and the second long-wave infrared reception strip 6 are set as a diverging type. The diverging type is provided with a flare at the opening for receiving the long-wave infrared rays 14, and as much as possible, the long-wave infrared rays 14 that are not parallel to the cross-section of the pipeline due to diffuse reflection are received, improving the effectiveness of the measurement results and ensuring that the long-wave infrared rays 14 emitted by the long-wave infrared emission strip 3 are received by the first long-wave infrared reception strip 4 and / or the second long-wave infrared reception strip 6.

[0030] Another specific feature of the present invention is that the reflection-absorption infrared hollow column 5 includes a hollow column body and carbon dioxide gas 11 filled in the hollow column body. The side wall of the hollow column body close to the long-wave infrared emission strip 3 is set as quartz glass 10 or the outer side wall is fully pasted with quartz glass 10. Since the long-wave infrared rays 14 are difficult to penetrate quartz glass 10, the long-wave infrared rays 14 emitted by the long-wave infrared emission strip 3 are reflected when encountering quartz glass 10, and the long-wave infrared rays 14 that enter the hollow column body through diffuse reflection are absorbed by the filled carbon dioxide gas 11.

[0031] Another specific feature of the present invention is that the outer side surface of the quartz glass 10 is provided with a first infrared reflection coating 9 to further reflect the long-wave infrared rays 14 emitted by the long-wave infrared emission strip 3. The inner side surface of the side wall of the hollow column body opposite to the quartz glass 10 is provided with a second infrared reflection coating 13 to reflect the long-wave infrared rays 14 that enter the hollow column body and prevent them from passing through the hollow column body and being received by the first long-wave infrared reception strip 4, ensuring the effectiveness of the monitoring. Preferably, the materials of the first infrared reflection coating 9 and the second infrared reflection coating 13 are set as a combination of vacuum infrared coating and metal coating to ensure a high reflectivity of the long-wave infrared rays 14.

[0032] Furthermore, except for the side made of quartz glass, the other sides of the hollow column body are all provided with high-transparency thin-wall resin 12 or the outer side wall is fully pasted with high-transparency thin-wall resin 12. Utilizing the principle that long-wave infrared rays 14 can penetrate the resin, the long-wave infrared rays 14 with diffuse reflection in the water layer 31 enter the reflection-absorption infrared hollow column 5 and are absorbed by the filled carbon dioxide gas 11. Preferably, the high-transparency thin-wall resin 12 is set as hard resin.

[0033] Furthermore, a non-damping pulley is installed on the inner wall of the hollow column body slide rail 7 to ensure that there is no obstruction when the reflection-absorption infrared hollow column 5 makes a reciprocating motion inside it. Preferably, the hollow column body slide rail 7 is integrally injection-molded with the pipeline.

The purpose is to raise the measuring water level for the measuring pipe section 27, slow down the water flow to form a laminar steady state, and make the measurement data more accurate; The diameter of the water outlet pipe section 25 is the same as that of the drainage pipe during normal construction and installation. The diameter of the pipe socket 1 should be adapted to the diameter of the socket of the existing national standard drainage pipe to meet the installation requirements.

[0036] Another specific feature of the present invention is that the laminar flow and stable flow sedimentation section 28 is provided with a sunken part, and the bottom wall of the sunken part is lower than the bottom wall of the measuring pipe section 27. When rain and sewage flow through this place, the water flow is slowed down to form a laminar steady state. At the same time, sediment and other pollutants are precipitated in the sunken part, making the measurement data of the measuring pipe section 27 by the monitoring device for intelligently monitoring the situation of the underground rain and sewage pipeline more accurate. Further, the cross-section shape of the output end of the water inlet pipe section 29 is circular, the shape of the input end of the measuring pipe section 27 is rectangular, and the cross-section of the output end of the water inlet pipe section 29 is larger than the cross-section of the input end of the measuring pipe section 27.
