Description

Technical Field

[0001] The present invention relates to the technical field of leakage emergency rescue, and particularly relates to an emergency rescue device for water pipeline leakage. Background Art

[0002] In the modern water conservancy infrastructure system, as the core carrier of the urban water supply network and cross-regional water diversion projects, the safe operation efficiency of water pipelines directly determines the regional water resource allocation efficiency and the reliability of the public water supply system. During the long-term service of such underground engineering facilities, they are faced with complex and changeable mechanical and environmental coupling effects, including but not limited to the continuous action of high-pressure hydraulic loads, the dynamic migration of formation media, the progressive erosion of chemical corrosion, and the sudden impacts of geological disasters such as seismic activities and freeze-thaw cycles. The combined action of these factors is extremely likely to induce the expansion of microcracks in the pipeline structure, ultimately leading to leakage accidents.

[0003] The fissure leakage of water pipelines has a significant chain-breaking effect: First, the abnormal fluid pressure at the leakage point will trigger the redistribution of the pipeline stress field, accelerating the material fatigue damage in the adjacent area, forming a vicious cycle of "damage-leakage-re-damage"; Second, continuous leakage will lead to a significant loss of annual runoff. According to the statistical data of the Ministry of Water Resources, the annual leakage rate of urban water supply networks in China generally exceeds 12%, and structural leakage of pipelines is the main inducement; More seriously, the seepage field disturbance caused by leakage will induce the seepage failure of the soil around the pipeline, forming cavitation and liquefaction areas, which will further lead to secondary disasters such as roadbed settlement and underground cavity expansion. The pipeline leakage accident that occurred along the subway line in a municipality in 2018 caused a ground collapse of up to 300 cubic meters, directly threatening the settlement safety of surrounding buildings. In addition, the diffusion of groundwater pollution caused by leakage will also disrupt the regional hydrogeological balance, forming a persistent ecological environment risk.

[0004] The current leakage disposal mode commonly adopted in the industry still mainly relies on passive response, relying on traditional means such as manual inspection and acoustic detection for post-event positioning. Its technical limitations have shown multiple defects: First, the detection accuracy is insufficient, resulting in a leakage point positioning error often exceeding 10 meters, making it difficult to achieve precise repair; Second, the response timeliness is poor. On average, it takes more than 72 hours from the discovery of leakage to the implementation of plugging. During this period, continuous leakage exacerbates the risk of secondary disasters; Third, it is difficult to avoid the secondary damage to urban traffic and underground pipe networks caused by traditional excavation and repair methods; Fourth, there is a lack of preventive maintenance strategies based on the whole life cycle, and the initiation and expansion of microcracks cannot be effectively curbed. These technical shortcomings make the existing disposal system difficult to meet the high timeliness and high precision requirements of modern intelligent water service systems for leakage prevention and control. It is urgent to break through the technical bottlenecks of pipeline health monitoring and intelligent early warning and establish an active defense leakage prevention and control system. Summary of the Invention

[0005] In view of the problem of emergency treatment for leaks occurring during the operation of long-distance water conveyance pipelines, the present invention provides an emergency rescue device for solving leaks in long-distance water conveyance pipelines, aiming to quickly respond to and effectively handle pipeline leakage incidents, slow down the damage risk caused by leakage through a series of measures, gain time for subsequent repairs, reduce the economic losses and potential safety hazards caused by pipeline leakage, ensure the stable operation of the water conveyance system, and reduce water resource losses.

[0006] The solution adopted by the present invention to solve its technical problems is as follows: An emergency rescue device for water conveyance pipeline leakage includes a plurality of annular stabilizers sleeved on the pipeline. The stabilizer includes an elastic inner lining, a fixed-configuration modular water bag, a fixed ring, a first snap ring, a second snap ring, and a housing. The elastic inner lining is sleeved on the pipeline, and the fixed-configuration modular water bag is sleeved on the elastic inner lining. An inlet valve and an outlet valve are respectively installed on both sides of the fixed-configuration modular water bag. The fixed ring is sleeved on the fixed-configuration modular water bag. The fixed ring is provided with an annular surface transition piece extending laterally outward. The first snap ring and the second snap ring are fixedly arranged at equal distances on the side surface of the annular surface transition piece. The first snap ring and the second snap ring are coaxial with the fixed ring, thereby dividing the side surface of the annular surface transition piece into three circular ring empty slots. The housing is sleeved on the outside of the annular surface transition piece. A sensor and a positioning component are installed on the inner circumferential surface of the housing. A folding protective film is installed in the circular ring empty slots. Limiting guide grooves are provided on the inner sides of the housing, the first snap ring, and the second snap ring. A group of motors are symmetrically fixed on the outer circumferential surface of the housing. Wire holes passing through the housing, the first snap ring, and the second snap ring at the same time are provided on the housing on both sides of each motor. A winding roller is installed on the output shaft of the motor. A bidirectional steel cable is wound around the winding roller. Both ends of the bidirectional steel cable pass through the wire holes and pass out from one of the circular empty slots. Both ends of the bidirectional steel cable extend and are connected to the folding protective films installed on adjacent annular stabilizers. By driving the winding roller to rotate with the motor, both ends of the bidirectional steel cable can be synchronously wound up, so that the steel cable pulls the folding protective film to unfold. The unfolded protective film is sleeved on the outside of the pipeline to form a water storage bag, providing temporary protection for the pipeline leakage position.

[0007] Preferably, the sensor includes a vibration sensor, an acoustic wave sensor, and a pressure sensor. An even number of vibration sensors, acoustic wave sensors, and pressure sensors are evenly distributed circumferentially on the inner side of the housing. The sensor signals are compared by a logic circuit and then a control instruction is output.

[0008] Preferably, the housing is a circular ring composed of two symmetric semi-circular rings spliced together. The two ends of the semi-circular ring are provided with laterally extending ear plates on the outside. Opposite pin holes are provided on the ear plates. The two semi-circular rings are formed into a circular ring-shaped housing by pins or bolts. The inner side surface of the housing presses against the fixed ring to fix the device.

[0009] Preferably, four stabilizers form a group, and the four stabilizers in each group are equidistantly distributed along the pipeline. The adjacent stabilizers are linked by steel cables to achieve emergency treatment of water pipeline leakage.

[0010] Preferably, magnetic strips are embedded at the edges of the folded protective film. One end of the folded protective film contacts the annular transition part of the fixed ring part and is fixed by a clamp, and the other end is sleeved in the limit guiding groove by the magnetic strip and connected to the steel cable.

[0011] Preferably, the fixed configuration modular water bag is a semi-circular hollow water bag. Water inlet valves and water outlet valves are installed at both ends of the fixed configuration modular water bag. Two semi-circular fixed configuration modular water bags are installed up and down outside the elastic inner lining and are sealed and fixed by buckles or zippers, which is convenient for installation and disassembly.

[0012] Preferably, there are two groups of symmetrically distributed wire holes along the circumference on the outside of each semi-circular ring shell. One group of wire holes forms a 45° angle with the plane where the semi-circular ring is located, and the other group of wire holes forms a 135° angle with the plane where the semi-circular ring is located, which is convenient for the steel cable to pass through and connect to the motor.

[0013] The beneficial effects of the present invention: The water pipeline leakage emergency rescue device provided by the present invention has the elastic inner lining of the stabilizer fitting the pipeline to provide a firm connection. The modular water bag is locked outside the elastic inner lining by bolts, which can block the leaked water body. The internal water pressure change is monitored in real time through the pressure sensor. When the water pressure reaches the preset threshold, its water inlet and outlet valves can flexibly control the water flow in the water bag, solving the problem that the traditional device cannot flexibly assist in the rescue.

[0014] The fixed ring part, the buckle ring and the outer shell cooperate to enable the device to resist external force impacts and water pressure changes; the pre-folded protective film is folded in a "Z" shape and is unfolded by cable drive after the motor is triggered. The magnetic strip cooperates with the clamp and the limit guiding groove to ensure that the protective film accurately fits the device and prevents the leakage from spreading. The motor provides stable power for it. The sensor assembly collects data through circumferentially distributed sensors and analyzes it through algorithms and pattern recognition technologies to quickly judge the leakage and initiate emergency measures. Multiple stabilizers are equidistantly distributed along the pipeline and work together to provide all-round protection for the water pipeline, reducing resource waste and environmental pollution, reducing the risk of pipeline damage, improving the reliability and operation efficiency of the water delivery system, and maximizing the emergency rescue efficiency.

Detailed implementation mode

[0017] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below.

[0018] Embodiment 1: The present invention provides an emergency repair device for water pipeline leakage, which is used for emergency treatment of water pipeline leakage, such as Figure 1 shown, a plurality of annular stabilizers 1 are sleeved side by side on the water pipeline. A sealed protective film is formed by the linkage and stretching between the annular stabilizers 1. The protective film is sleeved at the pipeline leakage position to prevent the expansion of the accident range. At the same time, it can quickly respond to positioning, facilitating subsequent maintenance and treatment.

[0019] Specifically, as Figures 2 - 5 shown, the annular stabilizer 1 includes an elastic inner lining 100, a fixed-configuration modular water bag 110, a fixed ring 120, a first snap ring 130, a second snap ring 140 and an outer shell 150. The elastic inner lining 100 is sleeved on the pipeline, the fixed-configuration modular water bag 110 is sleeved on the elastic inner lining 100, and the fixed ring 120 is sleeved on the fixed-configuration modular water bag 110.

[0020] Among them, the elastic inner lining 100 is tightly sleeved on the water pipeline and fits the pipeline. Its advantage is to absorb the harmful energy generated by pipeline vibration and enhance the stability of the device.

[0021] The fixed-configuration modular water bag 110 is a semi-circular hollow water bag. An inlet valve and an outlet valve are installed at both ends of the fixed-configuration modular water bag 110. Two semi-circular fixed-configuration modular water bags 110 are installed on the outside of the elastic inner lining 100 in an up-and-down distribution and are sealed and fixed by snaps or zippers, which is convenient for installation and disassembly.

[0022] The water bag is equipped with a pressure sensor, which can accurately monitor the internal water pressure changes in real time. When the water pressure reaches the preset threshold, the water inlet and outlet valve connected to the annular side cover 160 can flexibly control the water flow of the water bag according to actual needs, dynamically adjust the working state of the water bag, and effectively prevent water leakage.

[0023] The fixing ring 120 extends laterally outward to form an annular surface transition piece. The annular surface transition piece serves as the lateral support frame of the entire device, which helps to evenly disperse the load and improves the stability of the overall structure. The first snap ring 130 and the second snap ring 140 are two semi-circular rings with different ring diameters, having an inner circumferential surface, an outer circumferential surface, and two parallel side surfaces, and are equidistantly installed on both sides of the annular surface transition piece.

[0024] On each semi-circular ring, holes are drilled through the inner circumferential surface and the outer circumferential surface of the semi-circular ring in a direction perpendicular to the plane of the semi-circular ring and forming angles of 45 degrees and 135 degrees with one of the side surfaces. The advantage is that it is convenient for the steel cable 240 to pass through the device and connect to the motor 210. Machine screw holes 131 and machine screw holes 141 are respectively provided on the first snap ring 130 and the second snap ring 140, and are fixed to the fixing ring 120 by machine screws, significantly improving the strength and rigidity of the overall structure and facilitating disassembly and maintenance.

[0025] The first snap ring 130 and the second snap ring 140 divide the device into circular ring slots with three gears: low, medium, and high. When in use, different gears can be selected according to pipes with different conditions. The advantage is that the circular ring slots with different gears enable the device to adapt to water conveyance pipes with different pipe diameters and water pressures, enhancing the versatility and flexibility of the system; pre-selecting the appropriate gear ensures the safety and stability of the device during operation, preventing the water pressure from being too large to break through the protective film and damage the device.

[0026] The outer shell 150 is a circular ring composed of two symmetric semi-circular rings spliced together. The end of the semi-circular outer shell 150 extends laterally outward to form an ear plate with a pin hole 121. The design of using a pin or bolt to cooperate with the pin hole 121 fixes the two semi-circular outer shells 150 into one body. The advantage is that the installation and disassembly of the outer shell 150 are convenient, and the ear plate structure can withstand large radial and axial forces, ensuring the stability of the spliced circular ring outer shell 150. The inner side surface of the outer shell 150 presses against the fixing ring 120, so that the entire stabilizer 1 is firmly sleeved on the water conveyance pipe.

[0027] As Figure 7As shown, there are two sets of symmetrically distributed holes along the circumference on the outer side of each semi-circular ring housing 150: one set forms a 45° angle with the plane of the semi-circular ring, and the other set forms a 135° angle, facilitating the passing of the steel cable 240 through to connect the motor 210. The symmetry centers of these two sets of holes are both located on the straight line passing through the center of the semi-circular ring and perpendicular to the plane of the semi-circular ring, and the two sets of holes are symmetric with respect to this straight line as the axis of symmetry. The advantage is that the holes are symmetrically distributed along the circumference, making full use of the space, which is beneficial for the force exerted by the steel cable 240 to be evenly distributed on the circumference, reducing vibration and imbalance, and enhancing the stability of the system.

[0028] The sensors are circumferentially distributed on the inner side of the housing 150. The sensors provided are vibration sensors, acoustic wave sensors, and pressure sensors. The sensor signals are compared by a logic circuit and then control instructions are output. The advantage is that an even number of vibration sensors, acoustic wave sensors, and pressure sensors are evenly distributed, ensuring the reliability of data monitoring. Through in-depth comparison and intelligent analysis, control instructions are accurately and efficiently output, effectively improving the control efficiency and decision-making quality.

[0029] The annular side covers 160 are installed on both sides of the fixed ring member 120. The fixed ring member 120 is provided with opposite pin holes 121. The annular side covers 160 are connected by pins or bolts, and the fixed configuration modular water bag 110 is fixed within the fixed ring member 120 and the annular side covers 160. The advantage is that the fixed configuration modular water bag 110 can be fixed inside the device to prevent it from loosening and slipping; the pin or bolt connection method makes the annular side cover 160 easy to disassemble, facilitating the replacement and repair of the internal fixed configuration modular water bag 110. The annular side cover 160 is also connected to the water inlet and outlet valves of the fixed configuration modular water bag 110, facilitating the control of the water inlet and outlet of the fixed configuration modular water bag 110.

[0030] The pre-folded protective film 220 is stacked in a "Z" shape in three equally spaced circular empty grooves on the left and right of the first snap ring 130 and the second snap ring 140 on both sides. The advantage is that the "Z" shape has strong stability. When the protective film is stacked, it is neat and orderly, not easy to loosen and deform, and the arrangement is more compact, greatly reducing the storage space and facilitating storage; the edge of the pre-folded protective film 220 is embedded with a magnetic strip. One end contacts the ring surface transition part of the fixed ring member 120 and is fixed by a clamp. The other end is fixed through the limit guide groove 230 and is connected to the steel cable 240, facilitating the subsequent unfolding of the protective film by pulling with the steel cable 240.

[0031] The bottom of the motor 210 is fixed above and below the outer shell 150 by bolts. During operation, it is tightly connected and well-fixed to the steel cable 240. The advantage is that the motor 210 can always be in a dry position, ensuring stable power transmission while the motor 210 operates safely. The bolt fixation above and below can evenly disperse the force generated by the operation of the motor 210 onto the outer shell 150, preventing excessive local stress, reducing the risk of damage to the outer shell 150 and the motor 210, and extending the service life.

[0032] The limit guiding groove 230 is adapted to the magnetic strip, and a magnetic component that attracts the magnetic strip is arranged inside. The advantage is that the magnetic attraction helps the protective film to be quickly and accurately centered, and the connection is strengthened through the adsorption force, effectively preventing the protective film from falling off; when the pipeline leaks, the motor 210 is triggered to pull the steel cable 240. After the magnetic strip slides and separates along the limit guiding groove 230, the steel cable 240 pulls the protective film to cover the surface of the pipeline, so that the protective film unfolds to form a capsule-shaped water storage cavity. The advantage is that the capsule-shaped water storage cavity has a high water storage efficiency and can improve the water storage efficiency.

[0033] During the process of the steel cable 240 pulling the protective film, one end of the steel cable 240 is connected to one end of the protective film through a fixed buckle, and the other end passes through the first buckle ring 130, the second buckle ring 140 of the adjacent device, and the 45-degree and 135-degree holes on the annular surface of the outer shell 150 to connect the motor 210. After the motor 210 is triggered, the protective film is driven to unfold through the steel cable 240.

[0034] Four devices are grouped together and are evenly distributed along the water conveyance pipeline during operation. The advantage is that they can work together, comprehensively cover the water conveyance pipeline, and rely on the collaborative induction within the group to obtain leakage information from different angles, quickly integrate and analyze it, greatly improving the emergency response speed, quickly containing the expansion of the leakage, and realizing the emergency treatment of the leakage of the water conveyance pipeline.

[0035] The specific usage method is as follows: During operation, four identical devices are grouped together and work together. The pre-folded protective film 220 is folded in a Z shape and fixed in the circular ring empty groove. One end of the steel cable 240 is fixedly connected to the protective film in a suitable circular ring empty groove in advance according to the size of the water conveyance pipe diameter, the flow velocity and water pressure in the pipe, etc., and the other end is connected to the motor 210 of the adjacent device. For example, one end of the steel cable 240 is connected to the protective film in the corresponding circular ring cavity in Device 1, and the other end passes through the 45° / 135° hole 132 to connect the motor 210 of Device 2. Devices 2 and 3, and Devices 3 and 4 are connected in the same way, and the connection path is generally high in the middle and low on both sides. When the pipeline in the area leaks, different types of sensors circumferentially distributed on the inner side of the outer shell 150 detect the signal emitted by the leakage of the water conveyance pipeline, send an alarm to the cloud through the positioning component and send the GPS positioning signal in real time, which is convenient for the staff to quickly locate the problem area and complete the subsequent processing.

[0036] After signal comparison by the sensor, the motors 210 above and below the housing 150 start to drive and pull the steel cable 240. The pre-folded protective film 220 is driven by the steel cable 240 to unfold to form a capsule-shaped sealed cavity. When the steel cable 240 is pulled to the end, it is adsorbed and fixed through the limit guiding groove 230 and the magnetic strip embedded in the port of the protective film.

[0037] The internal water pressure change is monitored in real time by the pressure sensor. When the water storage volume in the cavity reaches the threshold, the pressure sensor monitors the signal and issues an instruction, and the water inlet valve of the water bag opens to receive the leaked water in the cavity to ensure the normal operation of the protective film. When the water storage volume in the water bag reaches the threshold, the pressure sensor controls the opening of the water outlet valve of the water bag, and controls the internal water pressure stability by draining water to the outside to prevent the protective film from bursting and damaging the device. After receiving the instruction, the staff drains the water in the water bag and the cavity during the water cut-off period for secondary utilization or supplies it to the water-requiring unit, etc., reinstalls this device for subsequent operations, and thus the emergency rescue work is completed.

[0038] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other implementation manners obtained by those of ordinary skill in the art without creative efforts belong to the scope protected by the present invention.
