[0033] Embodiments of the present application will be described in greater detail below with reference to the accompanying drawings. While only preferred embodiments of the application are shown and described, it should be understood that the scope of the disclosure is not limited to the details of construction and arrangement of the components set forth in the following description or illustrated in the drawings. The disclosure is capable of other embodiments and of being practiced or carried out in various ways.

[0034] The terminology used in the present disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the present application. As used herein, the terms "including", "comprising", "having" and the like are meant to be inclusive and are intended to indicate that there are no exclusive features. However, it is also intended that individual characteristics can be added and that not every implementation will include every characteristic.

[0035] It should be understood that, although the term "first", "second", "third" and the like can be employed in this disclosure to describe various information, the information should not be limited to such terms. These terms are only used to distinguish one category of information from another category of information. For example, the first information can also be referred to as the second information, and similarly, the second information can also be referred to as the first information without departing from the scope of the present application. Therefore, the features defined with "first", "second" can explicitly or implicitly contain one or more of the features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise specifically limited.

[0036] All terms used herein, including technical and scientific terms, have meanings commonly understood by one of ordinary skill in the art, unless otherwise defined. It should be noted that the terms used herein should be interpreted as having meanings consistent with the context of the present specification, and should not be interpreted in an idealized or overly formal manner.

[0037] The relevant pipe network system is composed of pipes and shafts, and the pipes and shafts are mostly connected by socket connection. Based on years of experience and observation and thinking in the development process, the inventors have summarized the following problems existing in the related technology.

[0038] On the one hand, the butt joint angle adaptability is poor, and the construction is difficult. Specifically, the socket port position and direction of the existing shaft are fixed, and the pipe laying needs to be adjusted according to the actual terrain, which leads to the difficulty in matching due to angle deviation during installation. For example, the socket connection requires the socket and the socket to be strictly aligned, but the flexible socket connection can adapt to a certain angle adjustment (such as well seat access method or gradual joint), which still relies on the accuracy of manual operation, and the construction efficiency is low and misalignment is easy to occur. In addition, the structure of pipe stiffening ribs and the like can further limit the angle adjustment.

[0039] On the one hand, the sealing reliability of the socket is insufficient, and leakage is easy. Specifically, the sealing of the existing socket connection mainly depends on the rubber ring or the packing, which belongs to the detachable structure, and is easy to slip and leak due to material aging, shaft settlement or pipe stress deformation in long-term use. For example, if the rubber ring is not uniformly pressed into the ring groove or is squeezed and twisted by external force, the sealing property will be directly damaged; the shaft is prone to settlement, and the settlement is also easy to cause sealing failure.

[0040] On the one hand, the dry pipe deposits accumulate, and there is a lack of active cleaning mechanism. The rainwater pipe network after rainwater and sewage diversion is in a long-term waterless state, which leads to the solidification of sediments such as silt and leaves in the pipe, and passive cleaning methods may not be able to completely remove them, eventually causing blockage, flooding and other accidents. Although the related technology proposes the design of smooth inner wall of the pipe or the gradual joint to reduce retention, it lacks intelligent monitoring and active flushing means, and cannot realize real-time early warning and multi-modal cleaning of sediments.

[0041] In summary, the relevant pipe network connection technology has problems such as poor angle adaptability, short sealing life, and difficult operation and maintenance, and there is an urgent need to provide a solution to improve the above problems.

[0042] The present application provides a pipe network with monitoring and maintenance functions. The pipe network with monitoring and maintenance functions can include the following technical features. The pipe network composition includes a high molecular material integrated shaft, a self-cleaning pipe material, a fusion joint adapted to the self-cleaning pipe material and the shaft, a high molecular material composite heating strip, a fusion joint between self-cleaning pipe materials, a fusion joint adapted to the self-cleaning pipe material, a fusion joint for installing a lead pipe, a CCD camera or other sensors (water level ultrasonic sensor, gas concentration sensor) installed in the lead pipe, a rainwater collection branch pipe, a high molecular material water collection tank, a water screen, a fusion joint adapted to the fusion joint, and a fusion joint adapted to the high molecular material water collection tank. An active cleaning nozzle system is installed in the pipe network.

[0043] In addition, the integrated connection of the pipe network uses hot melt connection to design the heater as a strip, and a high molecular material composite hot melt strip that can be spliced according to the shape of the connected pipe material. The hot melt strip can enter the radial gap between the pipe material and the fusion joint, and after being connected to the electric hot melt, it fills the gap, so that the pipe material, the hot melt strip, and the fusion joint are fused together in the axial direction, forming a high-strength integrated connection.

[0044] Figure 1 A structural diagram of a pipe network with monitoring and maintenance functions is shown. Referring to Figure 1 The main pipeline 1 includes a liquid conveying space. The main pipeline can be a single-walled pipe, a double-walled pipe, a corrugated pipe, a winding pipe, or a Kra pipe, etc., which is not limited here. The pipe wall can be a single raw material high molecular pipe or a composite pipe, etc.

[0045] The multi-pipe joint 3 is used to connect the pipes. The multi-pipe joint 3 can have at least two interfaces, each of which is used to connect one pipe. For example, the multi-pipe joint 3 can be a hot melt type joint, which melts the surface of the connection part by heating, then quickly butts the two melted parts and applies a certain pressure, and after cooling, forms an integrated and sealed joint. For example, this joint method is used in pipeline systems with high sealing performance requirements. The hot melt type joint has the advantages of high connection strength, good sealing performance, permanent connection, and can withstand high pressure. In addition, hot melt sheet material can also be used to realize hot melt integrated connection, further improving the connection reliability.

[0046] The multi-pipe joint 3 can be made of plastic, rubber, etc., such as polyethylene, polypropylene, etc., which has the advantages of light weight, corrosion resistance, and low price. In addition, the inner wall of the plastic joint is smooth, which can reduce the fluid resistance. It can be applied in the fields of municipal water supply and drainage, building water supply and drainage, agricultural irrigation, etc.

[0047] The liquid collection pipe 2 is connected to the main pipe through the ports of the multi-tube joint, and the liquid collection pipe 2 transports the collected liquid to the liquid transport space. In addition, the plurality of liquid collection pipes 2 can be connected through the joint 4.

[0048] The liquid collection pipe 2 is connected to the main pipe through the multi-tube joint. For example, a hot melt sheet can be used to realize hot melt integrated connection. At the connection between the main pipe and the liquid collection pipe, the main pipe extends in a first direction, the liquid collection pipe extends in a second direction, two ports of the multi-tube joint extending in the first direction are respectively sleeved with the ports of the two main pipes, and the port of the multi-tube joint extending in the second direction is sleeved with the liquid collection pipe. The first direction and the second direction are different, and the multi-tube joint is a prefabricated part.

[0049] In addition, the integrated connection mode can realize the integration of the pipe and the well, and intelligently detect the deposits in the pipe. The pipe material is a self-cleaning pipe material, and the inner wall of the pipe material is provided with an active cleaning system. The multi-modal active flushing and disinfection pipe network.

[0050] Referring to Figure 2 The pipe network with monitoring and maintenance functions described above can further include: a double pipe joint 6 for pipe communication; a vertical well 5 (such as an inspection well) connected to the main pipe through a double pipe joint passing through the opening of the vertical well 5; wherein the opening of the vertical well is opened on site according to the main pipe to be connected when the main pipe is laid; at the connection between the vertical well and the main pipe, the vertical well extends in a third direction, and the third direction is different from the first direction.

[0051] Referring to Figure 3 and Figure 4 The vertical well base is integrally welded after the depth of the vertical well 5 is adjusted on site. The side surface of the vertical well 5 is integrally welded with the double pipe joint, and the inner bottom surface and the inner side surface of the vertical well 5 base are provided with heating wires. When welding, the connecting pins are powered on to realize welding.

[0052] In some embodiments, the heating sheet and the joint can be used in combination to improve the connection firmness of the pipe. For example, a strip-shaped hot melt sheet (such as a polymer material composite hot melt strip) is wrapped around the head of the polymer material pipe and buckled into a ring. Then the polymer material pipe is inserted into the straight sleeve joint from both ends of the joint (hereinafter the straight sleeve joint is taken as an example for illustration), the end faces of the inserted pipes are in close contact, and the relative position of the straight sleeve joint and the connected pipes is fixed by the butt joint clamp. The electrical connection pins of the hot melt sheet (hereinafter the hot melt strip is taken as an example for illustration) are connected respectively, and the two hot melt strips are heated. At the same time, the butt joint clamp axial extension mechanism pushes the hot melt strips at both ends. The melted polymer material on the hot melt strip gradually fills the gap between the polymer material pipe and the straight sleeve joint, and the hot melt strip is continuously heated for a certain time and continuously pushed in. The inner surface of the joint and the outer surface of the pipe are melted and fused together with the melted polymer material on the hot melt strip. Stop heating the hot melt strip, and continue to keep the clamp axial extension mechanism pushing the hot melt strip. The fused material cools down under the continuous pushing of the clamp extension mechanism, realizing seamless belt pressing welding between the joint axial direction and the pipe axial direction at a certain distance, and forming an integrated connection.

[0053] Specifically, referring to Figure 2 and Figure 3 , the sleeve joint pipe 62 of the double pipe joint 6 is provided with a hot melt sheet in the sleeve joint gap of the main pipe 1, and / or the sleeve joint gap of the multi-pipe joint and the main pipe and / or the liquid collection pipe. Wherein, when the hot melt sheet is heated and pressurized, the space occupied by the hot melt sheet in the sleeve joint gap becomes larger.

[0054] For example, the joint includes: a multi-pipe joint, each port of the multi-pipe joint is respectively sleeved with a port of a polymer material pipe; a hot melt sheet, including a polymer material sheet and a heating element, the heating element is arranged in at least part of the polymer material sheet; wherein the hot melt sheet is arranged in the port of the polymer material pipe and the sleeve joint gap of the multi-pipe joint, so that after the polymer material sheet is hot-melted by the heating element, it is filled with the sleeve joint gap by external pressure (such as axial pressure of the pipe).

[0055] Wherein, the heating element can be an electric heating element embedded in the polymer material sheet; the two electrical connection ends of the electric heating element are located on the same side of the polymer material sheet, and there is no electric heating element in the set area of the end of the polymer material sheet on one side of the electrical connection end and the opposite side. The hot melt sheet includes but is not limited to: low-density polyethylene (LDPE), polyamide (PA), polyether sulfone (PES), thermoplastic polyurethane elastomer rubber (TPU), ethylene-vinyl acetate copolymer (EVA), high-density polyethylene (HDPE), etc. Optionally, the material of the hot melt sheet is the same as or at least partially the same as the material of the polymer material pipe, to improve the connection firmness.

[0056] For example, the electric heating element comprises a perforated metal structure or a mesh metal structure, which is arranged in the middle of the polymer material sheet. For example, the electric heating element comprises a resistance wire, the density of the resistance wire in the middle of the polymer material sheet is the highest, or the density of the resistance wire on one side of the polymer material sheet is less than that on the other side.

[0057] In some embodiments, at least one port of the multi-tube joint comprises a sleeving area for accommodating the polymer material tube, the thickness of the tube wall of the sleeving area is less than that of the non-sleeving area, the width of the polymer material sheet is greater than that of the sleeving area of the tube joint; and / or, the inner surface of the sleeving area of the multi-tube joint is in the same plane as the inner surface of the non-sleeving area; and / or, a stop component is arranged on the inner wall of the multi-tube joint for positioning the sleeved polymer material tube.

[0058] In some embodiments, the double-tube joint comprises an electric heating element arranged in the stop component; and / or, the electric heating element is arranged in the part area of the sleeved tube adjacent to the shaft; wherein, when the electric heating element is powered on, an external pressure is applied to the double-tube joint. The external pressure can make as much molten sheet as possible enter the gap between the joint and the tube, increase the contact area of the joint and the tube, and enhance the adhesion.

[0059] In some embodiments, the electric heating element comprises a perforated metal structure or a mesh metal structure, a first protruding edge is arranged on the side opposite to the side of the polymer material sheet where the electric connection end is arranged, so that the first protruding edge abuts against the stop component of the sleeved multi-tube joint or the inner end of the sleeving area of the multi-tube joint. Alternatively, the electric heating element comprises a perforated metal structure or a mesh metal structure, a second protruding edge is arranged on the side of the polymer material sheet where the electric connection end is arranged, so that the second protruding edge abuts against the port end surface of the sleeved multi-tube joint.

[0060] Specifically, the heating element is an electric heating element, and the two electric connection ends of the electric heating element are located on the same side of the polymer material sheet. Correspondingly, the polymer material sheet comprises a polymer material sheet body, and a first protruding edge structure is arranged on the side opposite to the side of the polymer material sheet body where the electric connection end is arranged, and the electric heating element is arranged in the first protruding edge structure.

[0061] In some embodiments, the polymer material sheet can comprise a polymer material sheet body and a second protruding edge structure; wherein, the second protruding edge structure is arranged on at least one surface of the polymer material sheet body, the material of the second protruding edge structure is the same as that of the polymer material sheet body, or the material of the second protruding edge structure is an elastic material. Alternatively, the electric heating element is arranged in the second protruding edge structure.

[0062] The polymer material of the polymer material composite hot melt band is an elastic polymer material, which is beneficial to fill the radial gap between the heating band and the pipe, and can ensure that a closed space is established during the welding process, realize pressure welding during the welding process, and exclude air to ensure the reliability and strength of the welding. The heating band is designed with a slope on the joint surface, which is beneficial to assembly and filling the gap between the joint and the heating band; the heater is made of a metal conductive material, and a hole type sheet heater is preferably used, which is beneficial to prevent the heating band from being squeezed together when subjected to axial force, thereby avoiding resistance changes and causing welding failure. The heater is located at the middle position of the heating band, and the width of the heater is smaller than that of the heating band, so as to ensure that the two ends of the assembled heating band have areas that cannot be melted in the axial direction, which is beneficial to establish a closed space and realize pressure welding.

[0063] In some embodiments, the double pipe joint 6 includes a sleeve pipe 62 and a stop component 61, and the other end of the sleeve pipe 62 for connecting the main pipeline is provided with the stop component. After the sleeve pipe 62 passes through the opening of the shaft, at least part of the surface of the stop component abuts against the inner surface of the shaft 5, and the double pipe joint is a prefabricated part.

[0064] For reference Figures 5 to 8 , the shape of the double pipe joint can be various, and the opening mode of the shaft 5 can be: according to the projection of the sleeve pipe 62 of the double pipe joint matched with the main pipeline 1 on the shaft 5, the sleeve pipe 62 of the double pipe joint is passed through the opening. Then the stop component 61 is fixedly connected with the side wall of the shaft.

[0065] It should be noted that the shape of the stop component 61 needs to be adjusted according to the shape and size of the connected pipe (shaft) to increase the fit of the stop component 61 with the surface of the pipe (shaft). Specifically, the stop component 61 and the sleeve pipe 62 can be integrally formed, or can be prefabricated parts, which are not limited here.

[0066] In addition, the stop component 61 and / or the sleeve pipe 62 can be provided with an electric heating element. By applying current to the two exposed electric connection terminals (see Figure 6 the two electric wires on the left side), the electric heating element generates heat to melt the surface of the stop component 61 and the sleeve pipe, and realizes welding.

[0067] For example, a welding head welded on a shaft, a welding head welded on a self-cleaning pipe, a welding head welded on a pipe welding head, and a welding head welded on a polymer material water collecting tank; the welding head has a surface matched with the inner surface of the corresponding welding product, the welding head has a heating wire integrated below the matched surface, and the matched surface of the welding head extends to form a convex edge of the welding head.

[0068] In some embodiments, the pipe network with monitoring and maintenance functions can further comprise a monitoring system. The monitoring system comprises a sensor and a data processing system connected by a line. The sensor is detachably arranged in a collection end of the lead pipe, which is connected to the main pipe and / or the liquid collection pipe. The information collected by the sensor is transmitted to the data processing system through the line via the main pipe and / or the liquid collection pipe. The sensor comprises at least one of the following: an image sensor, a toxic gas sensor, a temperature sensor, a flow sensor, and a flow rate sensor; and / or

[0069] A functional facility interface is arranged on the main pipe and / or the liquid collection pipe, and is used to connect the functional facility. The cable and / or pipe of the functional facility are arranged in the functional facility space of the main pipe through the functional facility interface.

[0070] Referring to Figures 9 to 12 The support rod of the functional facility can be fixedly connected to the main pipe 1 through a fusion joint. For example, the sleeve pipe 62 of the double pipe joint is used to connect and fix the support rod. The functional facility includes, but is not limited to, a street lamp, a traffic light, a camera, a wind speed collection device, an illumination collection device, a rainfall collection device, a signal station, a solar panel, and the like, which are not limited herein.

[0071] One end of the double pipe joint can be closed, such as by a transparent cover 12, to isolate the main pipe and the branch pipe. For example, a double pipe joint is provided with a sleeve pipe 62 at a location where information in the main pipe 1 needs to be collected, and a sensor is provided at the port to collect the information, and the transparent cover 12 can prevent the sensor 11 from being contaminated or damaged by liquid or gas in the main pipe 1. The signal collected by the sensor 11 can be transmitted to a server or host through a cable to achieve information processing. The cable can be guided and physically protected by the guide pipe 13. For example, the sensor includes but is not limited to: a temperature sensor (Temperature Sensor) for measuring temperature, such as a thermostat and a thermometer.

The maintenance system comprises a gas storage device 8 and a branch pipe connected to the main pipe 10. The main pipe 10 can be connected to the maintenance device 14. In this way, the maintenance medium from the gas storage device 8 and / or the liquid storage device 9 can be sprayed into the main pipe 1 through the maintenance device 14, so as to achieve active cleaning of the main pipe, reduce the risk of pipe blockage, and reduce maintenance costs. In addition, the stop component 61 of the double pipe joint is fixed on the inner wall of the main pipe 1, so as to fix the components such as the sensor 11 and the transparent cover 12.

[0075] For example, the lead pipe is a straight pipe with smooth inner and outer walls, which is integrated with the fusion joint by a high molecular material composite hot melt belt or is connected with the fusion joint by threads. The sensor is built-in and detachable in the lead pipe. The head of the sensor is sized to fit the inner diameter of the lead pipe, and the head is provided with a sealing ring for installation and sealing of the sensor. The tail of the sensor is connected with a hollow pipe material, and the tail of the hollow pipe material is connected with the lead pipe. The connection can adjust the position of the sensor installed in the lead pipe, and the inside of the hollow pipe material can pass the power supply line and the signal line of the sensor. The power supply mode of the sensor has various types, including solar energy, wind energy, and municipal power grid.

[0076] In some embodiments, the pipe network with monitoring and maintenance functions can also have a passive cleaning function. For example, the main pipe has a special structure and material composition, which can effectively reduce the probability of object attachment in a specific area, especially in an area prone to object deposition.

[0077] Specifically, the first cross-sectional area of the main pipeline is larger than the second cross-sectional area, the first cross-sectional area is the area of the half cross-section of the main pipeline away from the center of the earth in the post-laying state, and the second cross-sectional area is the area of the half cross-section of the main pipeline close to the center of the earth in the post-laying state.

[0078] For example, the cross-section of the main pipeline can be a special-shaped structure instead of a common circular pipe. The cross-section of one layer of the pipe wall of the special-shaped pipe includes: a first opening structure, which is located on the side of the special-shaped pipe away from the center of the earth in the post-laying state; a second opening structure, which is located on the side of the special-shaped pipe close to the center of the earth in the post-laying state; and a connecting structure, which connects the first opening structure and the second opening structure and forms a closed shape. The first projected area is larger than the second projected area, the first projected area is the projected area of the closed region of the first opening structure on the cross-section, and the second projected area is the projected area of the closed region of the second opening structure on the cross-section.

[0079] For example, the first opening structure is a horizontally symmetric structure; the second opening structure is a horizontally symmetric structure; and the connecting structure includes two horizontally symmetric and separately arranged sub-connecting structures, and the two ends of each sub-connecting structure are connected to one end of the first opening structure and the corresponding end of the second opening structure, respectively.

[0080] In addition, the first opening structure is any one of a circular arc structure, an elliptical arc structure, a polygonal structure, or a combination thereof; and the second opening structure is any one of a circular arc structure, an elliptical arc structure, a polygonal structure, or a combination thereof. See Figure 2 The main pipeline 1 is a fan-shaped or melon-shaped structure.

[0081] In some embodiments, the pipe wall of the main pipeline can include: a pipe wall outer layer; and a low-friction layer located on the side of the pipe wall outer layer close to the pipe axis. The friction coefficient of the low-friction layer is smaller than that of the pipe wall outer layer. The low-friction layer is formed by sintering low-friction material powder attached to the side of the auxiliary forming layer close to the pipe axis, and the low-friction material powder and the auxiliary forming layer in a hot melt state are co-extruded.

[0082] The pipeline is made of a material with a low friction coefficient on the inner surface of the pipe wall, which reduces the friction coefficient of the inner surface of the pipe and further reduces the possibility of blockage caused by precipitation and accumulation in the pipe. In addition, the price of some low-friction coefficient materials is much higher than that of ordinary pipe materials. Through the structure of the multi-layer composite pipe, the consumption of low-friction coefficient materials with high prices can be effectively reduced, and the cost of the pipe can be effectively reduced. In addition, the outer layer of the pipe wall can be selected from different materials according to the application environment to achieve the purposes of improving mechanical strength, oxidation resistance, and protecting the low-friction layer.

[0083] According to the embodiment of the present application, the low friction layer is formed by sintering the low friction material powder attached to the side of the auxiliary forming layer close to the axis of the pipe, so that the manufacturing efficiency of the low friction layer can be improved with the help of the auxiliary forming layer. Taking ultra-high molecular weight polyethylene (UHMWPE) as an example, because the molecular chain of UHMWPE is extremely long, and there are many random entanglements between the chains, the melt viscosity is extremely high, and the forming efficiency is only about 1% of that of ordinary plastic pipe products. The embodiment drags the low friction layer powder through the auxiliary forming layer, and then forms a multi-layer composite pipe through heating, thereby greatly improving the forming efficiency of materials with extremely high viscosity such as UHMWPE by several to several dozen times, and greatly reducing the time cost of production and manufacturing.

[0084] For example, the low friction layer is formed by sintering the low friction material powder attached to the side of the auxiliary forming layer close to the axis of the pipe, wherein the low friction material powder and the auxiliary forming layer in a hot melt state are co-extruded, or the low friction material powder and the auxiliary forming layer are formed by pressing and sintering, the molecular weight of the high molecular polymer is 1 million, such as 1.1 million, 3 million or 4 million, and the thickness of the low friction layer is less than 30 mm, 0.03≤M≤0.15, and M is the friction coefficient of the low friction layer.

[0085] In a specific embodiment, the self-cleaning function of the pipe network with monitoring and maintenance function includes active and passive cleaning. The passive self-cleaning pipe network uses self-cleaning pipe connection for self-flow acceleration cleaning. The active cleaning is realized by a pipe network active cleaning nozzle system. The system composition includes a spraying pipe system installed in the self-cleaning pipe, and a plurality of multi-angle spray heads are arranged on the spraying pipe. The active cleaning nozzle system has multiple cleaning media, preferably water and air. The two media are connected to the main pipe through corresponding branch pipes, and water or air is supplied through the water pump or air pump on the branch pipe. The spraying pipe corresponding to the sensor position is provided with at least one cleaning sensor spray head. The air supply branch pipe is sequentially connected with a one-way valve, an air pump, an ozone generator and a gas storage device. The water supply branch pipe is sequentially connected with a one-way valve, a water pump and a water storage tank.

[0086] The cleaning process can be shown as follows: the CCD video monitor installed in the guide pipe transmits the state in the pipe in real time; when the self-cleaning pipe is cleaned to a certain degree, a warning signal is sent to the rear-end monitoring platform; the rear-end monitoring platform sends a signal to the active cleaning nozzle system, the nozzle system starts the medium conveying pump, the cleaning medium is guided into the pipe by the nozzle, and the pipe wall is cleaned by the nozzle head distributed on the nozzle; the CCD monitoring cleans the cleaning degree, transmits the cleaning data in real time, and stops cleaning after reaching the standard. According to the cleaning effect, the CCD monitoring sends a signal, and the rear-end monitoring platform determines the medium type of the active cleaning nozzle system.

[0087] The disinfection process can be shown as follows: the toxic and harmful gas sensor installed in the guide pipe transmits the content of toxic and harmful gas in the pipe in real time; when the self-cleaning pipe is cleaned to a certain degree, a warning signal is sent to the rear-end monitoring platform; the rear-end monitoring platform sends a signal to the active cleaning nozzle system, the nozzle system starts the gas conveying pump and the ozone generating device, the gas containing ozone is guided into the pipe by the nozzle, and the pipe is disinfected by the nozzle head distributed on the nozzle; after the sensor monitors the concentration of toxic and harmful gas in the pipe, the rear-end monitoring platform sends a signal to stop the internal disinfection. (Toxic and harmful gases include methane, hydrogen sulfide, etc. which can be disinfected by ozone)

[0088] In addition, the liquid level in the pipe can also be monitored by the CCD, and the function monitoring can be realized.

[0089] The integrated connection proposed in the embodiment of the application adopts hot melting connection, the hot melting belt can be spliced according to the shape of the pipe, and is suitable for connecting pipes of various specifications. The hot melting belt enters the radial gap between the pipe and the joint, and fills the gap after being heated, so that the pipe, the hot melting belt and the joint are fused together under pressure in the axial direction. The requirements for the size of the pipe, the size of the joint and the installation angle precision can be greatly reduced, and the connection can be reliably realized.

[0090] The high molecular material of the high molecular material composite hot melting belt is an elastic high molecular material, which is beneficial to filling the axial gap between the joint and the pipe, can ensure that a closed space is established during the melting process, realizes pressure melting during the melting process, excludes air and ensures the reliability and strength of the melting.

[0091] In addition, by using a special melting clamp, the construction connection can be standardized, the connection qualification rate can be improved, and the elastic annular insert of the stretching mechanism head of the clamp can block the gap in the axial direction after entering the gap, establish a closed space and further ensure the melting under pressure. The gas and molten material can flow out under a certain pressure in the established closed space, so as to exclude the gas in the melting process and improve the melting quality.

[0092] In addition, the self-cleaning with the monitoring and maintenance function adopts active and passive cleaning. The passive self-cleaning pipe network adopts self-cleaning pipe connection to accelerate self-flow cleaning. The active cleaning is achieved by the spraying pipe system installed in the self-cleaning pipe and the monitoring system to realize active multi-angle, multi-medium spraying and disinfection cleaning, thereby solving the blockage and toxic and harmful substances in the existing pipe network.

When the amount of foreign matter such as soil, branches and leaves accumulated in the self-cleaning pipe reaches a certain standard, it will send a warning signal to the back-end monitoring platform.

[0110] Then, the back-end monitoring platform sends a signal to the active cleaning nozzle system, and the nozzle system starts the medium conveying pump immediately, and the cleaning medium is introduced into the pipe through the nozzle, and then the nozzle on the nozzle is used to clean the inner wall of the pipe.

[0111] In this way, the CCD can monitor the cleaning degree of the whole cleaning process and transmit the related cleaning data in real time. Once the cleaning standard is reached, the back-end monitoring platform will send a signal to stop the cleaning work.

[0112] Moreover, according to the specific requirements of the cleaning effect, the CCD monitoring sends a signal, and the back-end monitoring platform determines the type of medium used by the active cleaning nozzle system.

[0113] In addition, the disinfection process can include a toxic and harmful gas sensor installed in the guide pipe, which can transmit the content of toxic and harmful gases in the pipe to the back-end monitoring platform in real time.

[0114] When the concentration of toxic and harmful gases in the self-cleaning pipe reaches a certain threshold, a warning signal will be sent to the back-end monitoring platform.

[0115] At this time, the back-end monitoring platform sends a signal to the active cleaning nozzle system, and the nozzle system starts the gas delivery pump and the ozone generating device.
