It is the hub of heat exchange, heat distribution and system monitoring. The primary network refers to the pipe network connected between the first heat exchange station (or large regional boiler room) of the thermal power plant and the heat exchange station. The secondary network refers to the pipe network connected between the heat exchange station and the heat user.

[0003] During the process of hot water transportation by the circulating pump in the thermal power station, when the sealing ring between the circulating pump and the pipeline is aged and damaged, the pipeline leaks. However, since the surface of the hot water pipeline transports hot water, its surface temperature is higher than the dew point temperature of the surrounding air. The water vapor in the air condenses into water droplets and adheres to the pipe wall, affecting the judgment of the patrol personnel, resulting in the pipeline leakage cannot be discovered and dealt with in time; and during the long-term operation of the circulating pump, sometimes the motor is overloaded and heats up, causing the circulating pump to make loud noises and vibrations.

[0015] Compared with the related art, the heat exchange station early warning system based on big data provided by the present invention has the following beneficial effects: The present invention provides a heat exchange station early warning system based on big data. When the connection between the circulation pump and the water delivery pipeline leaks, water leaks to the surface of the water diversion pad under the action of gravity. The water diversion core is installed at the lowest point of the water diversion pad, and the top of the water diversion core is spherical, which increases the contact area between the water diversion core and the water diversion pad, and facilitates the water inside the water diversion pad to flow downward into the inside of the water diversion pad. The water diversion pad and the water diversion core are both composed of cotton yarn or sponge. The water diversion pad and the water diversion core have good water absorption. The water diversion core guides water into the water-expandable rubber strip. The water-expandable rubber strip is wound into a spherical shape, and water directly enters the center of the sphere through the water diversion core. The water-expandable rubber strip It starts to expand outward from the inside, so that the water-swellable rubber strip is quickly expanded, so as to facilitate the pushing of the metal spring sheet on one side of the water-swellable rubber strip to deform, so that the metal spring sheet slides from the side wall of the protrusion and contacts the metal block. The metal block and the metal spring sheet are electrically connected to the alarm light. The alarm light immediately alarms to remind the patrol personnel that there is a water leak here, and the alarm light uploads the information to the big data early warning platform. The big data early warning platform understands the pressure, water temperature and flow rate inside the water pipeline through the pressure sensor, temperature sensor and flow sensor inside the water pipeline. The data analysis module inside the big data platform analyzes and calculates the data to determine whether there is a water leak in this water pipeline. The severity of the water leakage in the water supply pipeline is detected, and the central processing unit inside the big data platform operates to open the driving mechanism, and the driving mechanism operates to open the regulating mechanism. The regulating mechanism rotates to reduce the flow rate of water inside the water supply pipeline. At the same time, the central processing unit operates to reduce the load of the circulating pump corresponding to this water supply pipeline, reduce the flow rate and pressure of hot water inside the water supply pipeline, and open the driving mechanism. The driving mechanism allows gas to enter the interior of the cylinder, push the piston rod and the rubber pad to move, so that the rubber pad is tightly pressed against the connection of the mounting flange, thereby increasing the sealing between the mounting flanges, slowing down the leakage rate of the water supply pipeline, and facilitating workers to repair it in time; similarly, when the When the circulation pump vibrates after generating load, the vibration sensor uploads the vibration information of the circulation pump to the big data early warning platform. The big data early warning platform obtains information such as the pressure, water temperature and flow rate inside the water pipeline through the pressure sensors, temperature sensors and flow sensors inside the water pipeline on both sides of the circulation pump. The central processing unit operates to open the regulating mechanism, and the regulating mechanism rotates to reduce the flow rate of water inside the water pipeline, while reducing the load of the circulation pump. The gas enters the cylinder to push the rubber pad tightly against the side wall of the mounting flange, thereby increasing the stability and firmness of the connection between the water pipeline and the water pipe, and avoiding water leakage at the connection between the water pipeline and the water pipe due to the vibration of the circulation pump.

When the internal data of a certain section of the water pipeline 22 deviates greatly from the internal data of other water pipelines 22, the data analysis module analyzes the past information stored in the information storage module. When the information deviation is too large, the data analysis module operates to turn on the alarm light 31 corresponding to this section of the water pipeline 22. The alarm light 31 alarms to remind workers to conduct inspections and eliminate risks. Step 2: When the connection between the water pipe 22 and the water pipe 1 leaks, water enters the water-expandable rubber strip 36 through the water diversion pad 32 and the water diversion core 35, and the water-expandable rubber strip 36 expands outward from the inside, pushing the metal spring 39 to move and contact the metal block 38. The metal block 38 and the metal spring 39 are both electrically connected to the alarm light 31. The contact between the metal block 38 and the metal spring 39 turns on the power of the alarm light 31 and immediately alarms to remind the patrol personnel that there is a water leak; and the alarm light 31 uploads the information to the big data warning platform, and the big data warning platform reads this water pipe 22. The data analysis module inside the big data platform analyzes and calculates the data to determine the severity of the leakage of the water pipe 22. The greater the difference between the pressure and flow inside the water pipe 22 and the pressure and flow inside other corresponding water pipes 22, the more serious the leakage of the water pipe 22; and the central processing unit inside the big data platform operates to open the electromagnet 71 to free the fixed shaft 52 from the restraint, and the central processing unit operates to open the air pump 61, one of the air inlet pipes 65 and the electromagnetic valve 67 on the side wall of the exhaust hose 41, and the air pump 61 flushes the gas into the interior of the fixed cylinder 62. , pushing the piston 63 and the slide bar 64 to move in the direction of the box body 53, the piston 63 pushes the internal gas of the fixed cylinder 62 into the interior of the exhaust hose 41, and the slide bar 64 drives the tooth plate 56 to move, and the tooth plate 56 drives the fixed shaft 52 and the adjusting plate 51 to rotate, and the circular adjusting plate 51 rotates to block the flow of hot water inside the water pipe 22, thereby slowing down the flow rate and flow rate of hot water inside the water pipe 22, and when the gas flows inside the exhaust hose 41, it enters the interior of the cylinder 43 through the connecting pipe 42, and the gas pushes the piston rod 45 and the rubber pad 44 to move, so that the The rubber pad 44 moves to press against the connection of the mounting flange 23, thereby increasing the sealing and stability between the mounting flanges 23 and slowing down the water leakage rate of the mounting flange 23; and according to the judgment of the data analysis module on the severity of the water leakage of the water delivery pipe 22, the rotation angle of the adjustment plate 51 inside the water delivery pipe 22 is appropriately adjusted. The greater the water leakage, the closer the rotation angle of the water delivery pipe 22 is to 90°, and the smaller the water volume inside the water delivery pipe 22 is, and the central processing unit operates to reduce the speed of the motor inside the circulating pump 1, reduce the load of the circulating pump 1, and reduce the flow rate and flow rate of the hot water inside the water delivery pipe 22; Step 3: When the circulating pump 1 vibrates after generating load, the vibration sensor 12 uploads the vibration information of the circulating pump 1 to the big data early warning platform. The big data early warning platform reads the pressure, water temperature, flow rate and other information inside the water pipe 22 on both sides of the circulating pump 1. The data analysis module inside the big data platform analyzes and calculates the data to determine the magnitude of the fault of the circulating pump 1. The larger the data transmitted by the vibration sensor 12, the greater the deviation between the pressure, water temperature and flow rate and other information on both sides of the circulating pump 1 and the data on both sides of other circulating pumps 1, indicating that the fault of the circulating pump 1 is greater; according to the magnitude of the fault, it is determined whether the circulating pump 1 continues to run. When it is determined that the circulating pump 1 cannot run, the central processing unit starts to operate. The driving mechanism 6 and the regulating mechanism 5 cause the regulating plate 51 to rotate 90°, close the water pipe 22, and at the same time close the circulating pump 1, allowing workers to perform maintenance; when it is determined that the operation can continue, the central processing unit operates to open the driving mechanism 6 and the regulating mechanism 5, and the regulating mechanism 5 rotates to reduce the flow of water inside the water pipe 22. At the same time, the central processing unit operates to reduce the speed of the motor inside the circulating pump 1 here, reducing the load of the circulating pump 1, and the gas inside the driving mechanism pushes the rubber pad 44 to fit tightly against the side wall of the mounting flange 23, increasing the stability and firmness of the connection between the water pipe 22 and the water pipe 11, and avoiding leakage at the connection between the water pipe 22 and the water pipe 1 due to the vibration of the circulating pump 1.
