Description

Technical Field

[0001] The present invention relates to the technical field of municipal engineering, and particularly to a multi-functional self-powered intelligent municipal pipeline well system and an adaptive charging and discharging method. Background Art

[0002] In the prior art, the following problems exist in municipal pipeline wells:

[0003] Single function: Traditional manhole covers only serve to seal pipeline wells and cannot monitor the concentration of harmful gases (such as hydrogen sulfide, methane) and the change of liquid level in the wells in real time. This results in the need for manual opening of the covers for inspection, which is not only inefficient but also poses safety hazards.

[0004] Power supply difficulty: Detection and monitoring instruments (such as flow meters, pipeline pneumatic valves, etc.) in wells in remote areas often cannot work properly due to lack of stable power supply; although the method of relying on external wiring can solve the power supply problem, it is costly, and it is difficult to supply power to multiple devices in the confined space of pipeline wells for a long period.

[0005] Easy to block: Debris (such as leaves, waste paper, etc.) in the pipeline is easy to accumulate, resulting in poor flow of water or other fluids (such as gases), and manual cleaning needs to be carried out frequently.

[0006] Data island: Lack of real-time data transmission function, it is difficult to give early warnings in a timely manner and link with the urban Internet of Things system, and the intelligent operation of infrastructure cannot be realized.

[0007] The Chinese patent document with the publication number CN213390245U provides a manhole cover with a detection function. Although it can detect the data in the well, it relies on single solar power supply and is prone to failure on rainy days, and fails to realize the data transmission function.

[0008] The Chinese patent document with the publication number CN112523915A provides a device for generating electricity by using the liquid pressure in the pipeline. It only provides a way to generate electricity on the liquid pipeline, does not provide a data transmission function, and is prone to form equipment failures or pipeline blockages by winding with debris in the pipeline.

[0009] In summary, there is an urgent need for a multi-functional self-powered intelligent municipal pipeline well system and an adaptive charging and discharging method to solve the problems of incomplete monitoring, unstable power supply, easy blockage and data island existing in traditional municipal pipeline wells.

[0029] 3. Intelligent anti-clogging: The impeller combines power generation and cutting functions, reducing the frequency of manual maintenance; the anti-clogging power generation module can achieve a three-level anti-clogging mechanism of "cutting - crushing - flushing": The two ends of the anti-clogging pipeline are open, and the middle part has a reduced diameter structure. According to Bernoulli's principle and the continuity equation in fluid mechanics, the flow velocity of the fluid in this section of the pipeline can be further increased, enabling the impeller to obtain a higher rotational speed, more energy conversion, and easier cutting of debris in the pipeline. For example, the size of the cut debris is ≤5mm, and the debris is more likely to be washed away naturally by the fluid in the pipeline to avoid residue. The natural flushing rate can reach over 95%, forming an anti-secondary clogging mechanism. Thus, for the multi-functional self-powered intelligent municipal pipeline well system provided by the present invention, its impeller combines the functions of cutting debris and power generation. Combined with the reduced diameter pipeline structure, the reduced diameter pipeline design not only increases the flow velocity (improving power generation efficiency) but also enhances the cutting ability (anti-clogging effect), and can prevent secondary clogging while improving power generation efficiency.

Its hydraulic impeller combines the function of cutting debris. The communication module is built-in with a chip to achieve data transmission to the cloud. The system has a reasonable structure and integrates functions of real-time monitoring, self-power supply, anti-clogging, and data transmission.

In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance. Among them, the terms "first position" and "second position" are two different positions.

[0041] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "installed", "connected", "connected" should be understood in a broad sense. For example, it can be a fixed connection or a detachable connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0042] As Figures 1 to 6 shown, the present invention provides a multifunctional self-powered intelligent municipal pipeline well system, including a pipeline well 1 and an intelligent manhole cover module 2 covering the pipeline well 1. External pipelines 5 communicating with the inside thereof are arranged on both sides of the pipeline well 1. A blockage prevention power generation module 3 and an Internet of Things pipeline device 4 are connected between the two external pipelines 5. The blockage prevention power generation module 3 and the Internet of Things pipeline device 4 are located inside the pipeline well 1. The intelligent manhole cover module 2, the blockage prevention power generation module 3, and the Internet of Things pipeline device 4 are connected through a communication cable 7 to form a power supply / communication loop.

[0043] In some embodiments, a display window 21, a solar panel 22, and an information code 23 are embedded in the top of the intelligent manhole cover module 2, and the display window 21, the solar panel 22, and the information code 23 are covered and protected by a protective layer 211. The protective layer 211 can be made of a high-strength transparent material such as a tempered glass protective film, and its protection level is IP68; the information code 23 can obtain the pipeline well system information, such as the pipeline well number, equipment maintenance records, equipment configuration, etc. after being scanned by the device.

[0044] Furthermore, a first equipment compartment 29 is provided at the lower part of the intelligent manhole cover module 2. The first equipment compartment 29 is embedded with a first battery 24, a first charge and discharge controller 25, a communication module 26, a measurement module 27, and a positioning module 28, and a card slot 294 is provided at the bottom. The card slot 294 is used to install a plurality of sensors 271 and a plurality of power transmission / information ports 318; one side of the first equipment compartment 29 is rotatably connected with a hatch door 291. One end of the hatch door 291 can rotate around the first equipment compartment 29, and the other end is provided with a sliding lock 293; the sliding lock 293 is V-shaped, and a semicircular groove is provided on the inner side, which is matched with a protruding semicircular sliding buckle 292 arranged on the outer side of the end of the first equipment compartment 29. The hatch door 291 can be quickly opened and closed by pressing the V-shaped sliding lock 293.

[0045] In this embodiment, the sensor 271 can be a methane sensor, a hydrogen sulfide sensor, a liquid level sensor, etc.; there are a plurality of power transmission / information ports 318. Thus, the intelligent manhole cover module 2 provided by the present invention integrates a methane / hydrogen sulfide sensor, a liquid level sensor, and a communication module (NB-IoT encrypted transmission) to realize real-time uploading of environmental data to the cloud, breaking through the traditional manual inspection mode.

[0046] Furthermore, the intelligent manhole cover module 2 has a self-cleaning function: one is to coat a hydrophobic nano-coating on the surface of the solar panel 22 to reduce the influence of dust accumulation on the power generation efficiency; the other is that the top of the intelligent manhole cover module 2 is a conical structure with a raised middle and slightly lower around, so that liquids such as rainwater can be diverted faster and take away dust and other stains, improving the self-cleaning effect.

[0047] Furthermore, the intelligent manhole cover module 2 has anti-overturning and anti-theft functions: one is that the sensor 271 includes a gas sensor, a liquid level sensor, and a horizontal gyroscope. The gas sensor is used to monitor the gas in the pipeline well, the liquid level sensor is used to monitor the liquid level in the pipeline well, and the horizontal gyroscope is used to monitor the displacement and tilt data of the manhole cover. When the deviation threshold is reached, an early warning is given to improve the safety of the manhole cover use; the other is that the positioning module 28 is data-connected to the horizontal gyroscope of the sensor 271. The positioning module 28 and the horizontal gyroscope of the sensor 271 are used together to comprehensively judge multiple data of the tilt degree, displacement amount, and trajectory, realize real-time alarm for abnormal opening, prevent the manhole cover from being stolen (when the manhole cover is stolen, there will be situations such as displacement, turning, and inclination), and the false alarm rate is lower.

[0048] Furthermore, the intelligent manhole cover module 2 has a risk warning function for the pipe network system. Upper and lower limit thresholds of relevant measurement data in the pipeline well are set in the communication module 26 to construct a pipeline health assessment model. Through cross-validation of the feedback data of the sensor 271 and the Internet of Things pipeline equipment 4, when the threshold range is exceeded, a risk warning level is output.

[0049] Furthermore, the communication module 26 adopts NB-IOT communication, which overcomes the disadvantages of traditional wireless communication modules such as LORA and Zigbee with too short transmission distance and the need to set up too many base station nodes. It realizes the connection between the on-line monitoring device and the remote monitoring center by setting only a few communication base stations within the small watershed range, and can effectively reduce the networking cost of the monitoring device.

[0050] In some embodiments, the anti-blocking power generation module 3 includes an anti-blocking pipeline 32 and a hydraulic power generation unit 31 installed above the anti-blocking pipeline 32; a second equipment cabin 311 is arranged outside the hydraulic power generation unit 31, and an equipment base 316 is arranged at the lower part of the second equipment cabin 311. The equipment base 316 is installed on the anti-blocking pipeline 32; a second battery 312, a second charge and discharge controller 313, a generator 314, and a planetary gear speed increaser 315 are arranged in the second equipment cabin 311. An impeller 317 is arranged in the anti-blocking pipeline 32, and the generator 314 and the planetary gear speed increaser 315 are connected to the impeller 317 at the lower part through a rotating shaft; the impeller 317 is used for power generation and cutting, and sharp cutting edges are arranged on its edge for cutting sundries entering the pipeline to prevent accumulation.

[0051] Optionally, the edge of the impeller 317 adopts a serrated cutting edge type using bionics principles, such as a shark tooth-like bifurcated structure, which can improve the cutting efficiency, and the material is high-strength stainless steel.

[0052] Optionally, the planetary gear speed increaser 315 is a commercially available high-efficiency transmission device, which includes a two-shaft gearbox. Through the coordinated action of multiple gears, it realizes power transmission and speed change, and is mainly used to convert low-speed input into high-speed output while maintaining a high transmission efficiency. The planetary gear speed increaser 315 is used for the transmission of the impeller 317 to increase the speed, thereby increasing the moment of inertia and further improving the power conversion efficiency of the generator 314.

[0053] Furthermore, both ends of the anti-blocking pipeline 32 are open, the middle part is reduced in diameter, and flanges 6 are arranged at both ends; the flanges 6 are used for the connection between the anti-blocking power generation module 3, the Internet of Things pipeline device 4 and the external pipeline 5, and can adapt to various pipe diameters according to actual needs.

[0054] In this embodiment, the anti-blocking pipeline 32 can realize a three-level anti-blocking mechanism of "cutting - crushing - flushing": its structure type with open ends and reduced diameter in the middle. According to Bernoulli's principle and the continuity equation in fluid mechanics, the flow velocity of the fluid in this section of the pipeline can be further increased, so that the impeller 317 obtains a higher rotation speed and more energy conversion, and it is easier to cut sundries in the pipeline. For example, the size of the cut fragments ≤ 5mm, and the fragments are more likely to be washed away by the fluid in the pipeline naturally to avoid residue, and the natural flushing rate can reach more than 95%, forming an anti-secondary blockage mechanism.

[0055] Therefore, in the multi-functional self-powered intelligent municipal pipeline well system provided by the present invention, the impeller 317 has both the functions of cutting debris and generating electricity. Combined with the reduced-diameter pipeline structure, the reduced-diameter pipeline design not only increases the flow rate (improving the power generation efficiency) but also enhances the cutting ability (preventing blockage effect), and can prevent secondary blockage while improving the power generation efficiency.

[0056] Further, the first storage battery 24, the second storage battery 312, and the communication module 26 are each provided with a plurality of power / information sending ports 318 at one end, which are matched with the power / information receiving heads 71 provided on the connecting cable 7; the power / information receiving heads 71 are of a cylindrical structure, and an annular groove is provided on the curved surface thereof; the power / information sending ports 318 are also provided with waterproof sealing rings 319.

[0065] Optionally, the positioning module 28 is used to accurately position the pipe well to improve the emergency response or equipment maintenance speed.

[0066] Optionally, all parts of the electronic components of the pipe well system are sprayed with nano protective materials to ensure the antistatic ability of the product, greatly reduce the adsorption of dust and the overall heat generation, extend the service life of the product, and reduce the maintenance cost.

[0067] In addition, the present invention also provides an adaptive charge and discharge method for a multi-functional self-powered intelligent municipal pipe well system, which uses the multi-functional self-powered intelligent municipal pipe well system described above. This method can be self-optimized and adjusted based on environmental data according to the pipe well monitoring data, via the charge and discharge controller and in combination with the communication module 26. The method includes:

[0068] 1. Obtain the weather forecast through the communication module 26 and dynamically adjust the priority of using the batteries of solar energy and hydroelectric power respectively; give priority to using the battery at the solar energy end on sunny days, and give priority to using the battery at the hydroelectric power end on rainy days;

[0069] 2. According to the day-night alternation and pipeline flow changes, the dual batteries adopt a "peak-valley complementary" mechanism. During the day, when the pipeline flow is low, the solar power end is preferentially used for power storage. At night, when the flow is high, the hydroelectric power generation end is preferentially used for power storage.

[0070] 3. An AI prediction model is introduced by the superior platform of the system. According to historical flow data, the charging and discharging process of the hydroelectric power generation end is optimized to better complement and adapt to the charging and discharging process of the solar power end during the day.

[0071] Among them, when there is sufficient sunlight during the day, the solar panel 22 on the top surface of the intelligent manhole cover module 2 is stored in the first battery 24 via the first charge and discharge controller 25, and then powers the corresponding communication module 26, measurement module 27, positioning module 28, and display window 21 to display the concentration of toxic and harmful gases and the possible water accumulation level height in the pipeline well 1 in real time. At the same time, relevant environmental information and equipment information are encrypted and transmitted to the cloud platform in real time via the communication module 26.

[0072] When the fluid enters the anti-blocking power generation module 3 through the external pipeline 5 and drives the impeller 317 to rotate, after being accelerated by the planetary gear speed increaser 315 and increasing the moment of inertia, it further accelerates the rotation, converts the mechanical energy into electrical energy through the generator 314, and stores it in the second battery 312 via the second charge and discharge controller 313. At the same time, the high-speed rotating impeller 317 uses its blades to cut debris such as leaves and waste paper in the pipeline. The size of the cut debris can be ≤ 5 mm, which is more easily washed away by the fluid naturally.

[0073] The entire system is powered by DC 12 / 24V, which is suitable for mainstream Internet of Things devices and uses a low-voltage DC circuit, effectively reducing the occurrence of electric shock accidents and improving the system stability and the safety of maintenance personnel.

[0074] Both ends of the anti-blocking pipeline 32 are open and the middle is reduced in diameter. According to Bernoulli's principle and the continuity equation in fluid mechanics, the flow velocity of the fluid in this section of the pipeline can be further increased, so that the impeller 317 can obtain a higher rotation speed, more energy conversion, and it is easier to cut debris in the pipeline. The debris is more easily washed away by the fluid in the pipeline naturally to avoid residue, forming an anti-secondary blockage mechanism. At the same time, it can also obtain a higher power generation efficiency at a lower pipeline fluid flow velocity.

[0075] The effective connection between the first battery 24 and the second battery 312 enables the solar energy and hydroelectric power to achieve complementary power supply, ensuring the all-weather stable power supply of the system.

[0076] The effective implementation of this system is fully applicable to new smart city construction or pipe network renovation projects, reducing the manpower input for municipal operation and maintenance. The cost of a single set of the system is 30% lower than that of traditional manhole covers + manual inspections.

[0077] In summary, the multifunctional self-powered intelligent municipal pipeline well system and the adaptive charging and discharging method provided by the present invention have an intelligent manhole cover module integrated with energy storage, communication, positioning, and (gas or liquid level, etc.) sensors, and are powered by dual energy sources through the top solar energy and pipeline hydraulic power generation units. The hydraulic impeller has the function of cutting debris, and the communication module is built with a chip to realize data transmission to the cloud. The system has a reasonable structure, integrating functions of real-time monitoring, self-power supply, anti-blocking, and data transmission.
