Description

Technical Field

[0001] This application relates to the field of underground pipelines, and in particular to an underground pipeline protection and monitoring device. Background Technology

[0002] Underground pipelines are pipes laid underground to transport liquids, gases or loose solids. In cities, underground pipelines are often used to discharge domestic sewage, rainwater and other liquid waste as well as small particulate solid waste.

[0003] Underground pipelines are very long, and it would be too costly to install detectors at every point. Therefore, it is difficult to monitor the entire underground pipeline. Underground pipelines are difficult to monitor. If cracks appear in the underground pipeline, sewage inside the pipeline will seep out and pollute the external underground environment. Summary of the Invention

[0004] To address the challenges and high costs associated with monitoring underground pipelines, this application provides an underground pipeline protection and monitoring device.

[0005] This application provides a protective monitoring device for underground pipelines, which adopts the following technical solution:

[0006] An underground pipeline protection and monitoring device includes a pipeline. A primary screening module and a secondary screening module are installed inside the pipeline. The primary screening module includes flow detectors installed on the inner walls of both ends of the pipeline, a processor, and a database. The flow detectors detect the water flow at the open surfaces at both ends of the pipeline and output corresponding water flow data to the processor. The processor calculates the difference in water flow data and compares it with threshold data stored in the database. If the difference in water flow data exceeds the threshold data, it outputs a start signal to the secondary screening module. The secondary screening module includes a detection ring slidably installed inside the pipeline. The detection ring is equipped with a scanner for scanning and identifying whether there are cracks in the inner wall of the pipeline. The detection ring is also equipped with a drive component for driving the detection ring to slide. The drive component and the scanner are activated upon receiving the start signal.

[0007] By adopting the above technical solution, the two flow detectors of the primary screening module are used to detect whether there is a leak in the pipeline. If the outflow detected by the flow detector at the pipeline outlet is less than the inflow detected by the flow detector at the pipeline inlet, it indicates that there is a leak in the pipeline. At this time, the processor determines that there is a crack in the inner wall of the pipeline, and then causes the detection ring of the fine screening module to slide, thereby driving the scanner to scan and identify the inner wall of the pipeline. By performing primary screening first and then fine screening, the probability of frequent start-up of the fine screening module is reduced. Frequent start-up of the fine screening module not only reduces its own lifespan and increases energy consumption, but also affects the normal drainage of the pipeline. However, by first judging whether there is a problem in the pipeline by the outflow and inflow, the energy consumption of the fine screening module is greatly reduced, the service life of the fine screening module is extended, and the probability of the fine screening module affecting the normal drainage of the pipeline is reduced, thereby improving the effectiveness of pipeline monitoring and reducing the difficulty of pipeline monitoring.

[0008] Optionally, a clearance annular groove is formed on the inner wall of the pipe. The fine screening module includes an electron-generating module disposed in the pipe. The electron-generating module is used to generate electricity for the drive component and the primary screening module. The electron-generating module includes a ring body, which is circumferentially arranged around the clearance annular groove. A rotating fan core is disposed at the circumferential center of the ring body. Parallel power-generating rings and magnetic rings are disposed on the inner ring sidewall of the ring body. Fan blades are disposed between the power-generating rings and the rotating fan core. The fan blades are inclined. The power-generating rings slide to cut the magnetic field lines of the magnetic rings to generate electricity.

[0009] By adopting the above technical solution, the generator module generates electricity to power the electrical components of the primary screening module and the fine screening module, achieving energy self-sufficiency and reducing the probability of the fine screening module not starting for extended periods while the external cable is continuously powered, thus achieving the goals of environmental protection and energy conservation. By installing the ring body within the clearance groove, the area of ​​the ring body directly impacted by the water flow is reduced, further minimizing the impact on the normal drainage function of the pipeline and reducing the probability of damage to the ring body from impact, thus protecting the ring body. The fan blades convert the impact of the water flow into rotational mechanical energy, and then into electrical energy, thereby reducing the impact force of the water, reducing the damage of water flow impact to pipelines and equipment, and extending service life.

[0010] Optionally, the power generation module further includes a wireless power transmission coil disposed within the ring body. The power generation ring is used to power the wireless power transmission coil and the primary screening module. The detection ring is provided with a battery for powering the drive assembly, and the wireless power transmission coil is used to charge the battery.

[0011] By adopting the above technical solution, wireless charging is achieved through a wireless power transmission coil. Since the frequency of pipe cracking is low under normal circumstances and the frequency of use of the fine screening module is low, the low power of wireless charging can also meet the charging needs of the battery. Furthermore, the use of wireless charging reduces the probability of live wires coming into contact with water flow, greatly enhances the waterproof and insulation performance, and reduces the probability of leakage causing impact on the environment or people.

[0012] Optionally, the inner sidewall of the ring is flush with the inner wall of the pipe, and a guide slope is provided on the inner wall of the pipe. The guide slope is inclined and connected between the inner wall of the clearance ring groove and the inner wall of the pipe. The detection ring includes a plurality of detection ring blocks, which are spliced ​​together in a ring shape. A connecting groove is provided at the end of each detection ring block. A connecting ring block is slidably disposed in the connecting groove. The connecting ring block is also inserted and slidably inserted into an adjacent connecting groove. The diameter of the opening section of the connecting groove is smaller than the diameter of the end section of the connecting ring block. An elastic element is provided between the bottom wall of the connecting groove and the side wall of the connecting ring block. The elastic element extends and retracts along the direction of the end of the connecting ring block near the opening of the corresponding connecting groove.

[0013] By adopting the above technical solution, the inner ring sidewall of the ring body is flush with the inner wall of the pipe, which further reduces the impact of water flow on the ring body. Through the guiding slope, the detection ring block can slide into the relief ring groove or slide into the inner wall of the pipe under the action of the driving component. Moreover, under the action of the connecting ring block, elastic element and connecting groove, the size of the detection ring block can be adapted to the size of the relief ring groove and the size of the inner wall of the pipe, which greatly increases the stability of the detection ring block when resting and working.

[0014] Optionally, a limiting groove is formed on the ring body, a limiting block is provided on the detection ring for insertion into the limiting groove, an electromagnet is provided on the inner wall of the limiting groove, and a magnet is provided on the limiting block for interaction with the electromagnet.

[0015] By adopting the above technical solution, when the detection ring rests and charges against the ring body, the limiting block is inserted into the limiting groove. When the detection ring rotates due to the external force of the water flow, the limiting block abuts against the inner wall of the limiting groove, limiting the rotation of the detection ring and thus improving the stability of the detection ring. By attracting the electromagnet and the magnet, the detection ring is attracted to the ring body, further enhancing the stability of the detection ring and reducing the probability of the detection ring slipping under the action of external environmental forces. Moreover, when the detection ring needs to work, the direction of the current flowing through the electromagnet can be changed to change the magnetism of the electromagnet, causing the electromagnet to repel the magnet, thereby giving the detection ring an initial speed for starting and accelerating the starting speed of the detection ring.

[0016] Optionally, the drive assembly includes a drive element and a rotating wheel. The rotating wheel is rotatably mounted on the detection ring. The output shaft of the drive element is connected to the rotating shaft of the rotating wheel. The rotation direction of the rotating wheel is inclined to the extension direction of the pipeline.

[0017] By adopting the above technical solution, the detection ring is controlled to slide by driving the rotating wheel to rotate through the driving component. The rotating wheel is set at an angle to the extension direction of the pipeline, so that the rotating wheel drives the detection ring to rotate and move forward in the pipeline. This causes the scanning and recognition range of the scanner to overlap, so that the scanner can completely cover the inner wall of the pipeline, reducing the probability of scanning and recognition errors and improving the accuracy and range of scanning and recognition.

[0018] Optionally, the pipe opening is provided with a plurality of filter screens, and the filter holes of the plurality of filter screens are arranged in an alternating manner.

[0019] By adopting the above technical solution, the filter screen with staggered filter holes can effectively block and filter filamentous impurities such as hair and grass, improve filtration efficiency, reduce the probability of pipe blockage, protect the normal operation of the pipe, and also protect the primary screening module and the fine screening module.

[0020] Optionally, a plurality of ball bearings are rotatably disposed on the side wall of the power generation ring, the ball bearings being used to make rolling contact with the side wall of the magnetic ring.

[0021] By adopting the above technical solution, the friction between the generator ring and the magnetic ring is transformed into rolling friction through ball bearings, which greatly reduces the friction between the generator ring and the magnetic ring and extends the service life of the generator ring and the magnetic ring.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. It greatly reduces the energy consumption of the fine screening module, extends the service life of the fine screening module, and also reduces the probability that the fine screening module will affect the normal drainage of the pipeline, thereby improving the effect of pipeline monitoring and reducing the difficulty of pipeline monitoring.

[0024] 2. Achieve environmental protection and energy conservation goals; reduce the impact on the normal drainage function of the pipeline, and also reduce the probability of the ring body being damaged by impact, thus protecting the ring body; reduce the impact force of water, reduce the damage of water flow impact to pipelines and equipment, and extend service life.

[0031] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0032] This application discloses an underground pipeline protection and monitoring device. (Refer to...)

In this embodiment, the flow detectors 12 can be water flow sensors, the processor can be an MCU, the processor is used to perform data signal calculation and processing, and the database is used to store water flow difference threshold data.

[0033] Reference Figure 2 and Figure 3The flow detector 12 is used to detect the water flow at both ends of the pipe 1 and output the corresponding water flow data to the processor. The processor can delay for a certain period of time based on the distance between the two flow detectors 12, that is, calculate the water flow data of the flow detector 12 at the outlet end with the water flow data of the flow detector 12 at the inlet end a certain period of time ago. This indicates that the water entering at the inlet end will only come out from the outlet end after a certain period of time. After calculating the difference between the two water flow data, it is compared with the water flow difference threshold data stored in the database. If the difference in water flow data exceeds the threshold data, it indicates that water is seeping out in the pipe 1, resulting in less water output than water input. The processor outputs a start signal to the fine screening module 2.

The three detection ring blocks 5 can be spliced ​​end to end to form a complete ring. The diameter of the spliced ​​detection ring block 5 is smaller than the cross-sectional diameter of the inner wall of pipe 1.
