Description

Technical Field

[0001] This invention is a water supply network pump group scheduling device, belonging to the field of water supply network technology. Background Technology

[0002] As the "blood vessels" of urban water supply, the water supply network bears the core mission of delivering tap water to various users, and its water delivery stability is directly related to the normal operation of the city. To ensure the water delivery capacity of the water supply network, the industry generally uses pump groups composed of multiple pumps connected in parallel as the core power source for water supply. However, the water consumption of the water supply network fluctuates significantly with peaks and troughs over time. To reduce equipment wear and energy waste caused by ineffective operation of pump groups, it is necessary to implement dynamic management and control through multi-objective coordinated scheduling of pump groups. That is, by adjusting the number and combination of pumps operating at different times, precise matching of water supply and demand can be achieved.

[0003] Currently, most pump group scheduling equipment still relies on either manual experience or simple optimization models, both of which have significant shortcomings: In manual scheduling, if a pump malfunctions and causes a water outage, staff may not be able to detect it in time, easily leading to a disconnect between scheduling instructions and actual water supply capacity, significantly increasing the risk of scheduling errors; while automatic scheduling can avoid the problem of delayed manual response, when a pump experiences hidden internal faults such as impeller wear, although the pump may not stop, the water supply may have decreased. The scheduling equipment may mistakenly interpret insufficient water supply as increased water demand, thus starting the backup pump, causing additional equipment wear and energy waste, as well as scheduling deviations, seriously affecting scheduling effectiveness and water supply quality. Summary of the Invention

[0004] To address the problems in the prior art, the present invention provides a water supply network pump group scheduling device.

[0005] The technical solution adopted by this invention to solve its technical problem is: A water supply network pump group scheduling device, comprising: The main body of the scheduler has a rectangular structure. A cylinder is connected to the left end of the main body of the dispatcher; The tube is connected to the left end of the cylinder; The mounting components are provided in two parts, which are symmetrically installed on the outer end of the cylinder, with the cylinder located between the two mounting components. A rotating shaft is rotatably connected to the right end of the tube, the rotating shaft passes through the tube, and the rotating shaft is located inside the cylinder; A limiting component is connected to the left end of the tube, and the left end of the rotating shaft is connected to the limiting component; A stop component is connected to the right end of the rotating shaft. The right end of the stop component is connected to the left end of the main body of the dispatcher, and the stop component is located inside the cylinder. A semi-circular plate is installed on the annular end of the rotating shaft, and the semi-circular plate is located inside the tube. The load-bearing block is connected to the rear end of the semi-circular plate, and the cross-section of the load-bearing block is triangular.

[0006] Furthermore, the stopping component includes a turntable, which is mounted on the right end of the rotating shaft and located inside the cylinder. A rectangular tube is provided at the lower end of the turntable, and a switch is installed inside the rectangular tube. The lower end of the rectangular tube protrudes upward to form a notch, and the notch extends to the front and rear ends of the rectangular tube, respectively. The lower end of the switch extends into the notch and is electrically connected to the main body of the dispatcher. A stabilizing component is rotatably mounted on the right end of the turntable and is located on the left side of the main body of the dispatcher. A driving component is installed on the inner wall of the cylinder and works in conjunction with the switch.

[0007] Furthermore, the stabilizing component includes a hollow tube, which is rotatably connected to the middle of the right end of the turntable. Multiple fixing rods are equidistantly installed on the outer end of the hollow tube, and the outer ends of the multiple fixing rods are all connected to the inner wall of the cylinder.

[0008] Furthermore, the driving component includes an arc-shaped box, which is installed on the inner wall of the cylinder and located on the lower rear side of the turntable. Multiple straight plates are equidistantly connected to the upper end of the arc-shaped box, and the straight plates extend into the arc-shaped box. The multiple straight plates are arranged in an arc-shaped structure, and each of the multiple straight plates has an arc-shaped head at its inward end. The arc-shaped head is used in conjunction with a notch or groove. An auxiliary device is installed inside the arc-shaped box.

[0009] Furthermore, the auxiliary device includes an electromagnet, which is installed on the bottom of the inside of the arc-shaped box, and the cross-section of the electromagnet is arc-shaped. Multiple partitions are installed at equal intervals on the upper end of the electromagnet, and the other end of the multiple partitions is connected to the top of the inside of the arc-shaped box. Rectangular plates are provided on the lower end of the multiple straight plates, and the rectangular plates and partitions are arranged alternately. Magnetic plates are installed on the lower end of the multiple rectangular plates, and the magnetic plates are located on the upper side of the electromagnet. The electromagnet and the magnetic plates are arranged to attract each other. Two first elastic elements are symmetrically installed on the upper end of the multiple rectangular plates, and the two first elastic elements are located on both sides of the corresponding straight plates. The other end of the first elastic elements is connected to the top of the inside of the arc-shaped box.

[0010] Furthermore, the limiting component includes a circular box, which is installed at the left end of the tube. The left end of the rotating shaft is rotatably connected to the circular box, and the rotating shaft extends into the circular box.

A transparent plate is provided inside the frame plate, and the transparent plate is located on the right side of the display part of the scheduler body.

[0013] The beneficial effects of this invention are as follows: When the water pump is running, the water flow velocity inside the pipe is stable. At this time, the semi-circular plate is in a stable, tilted position. When a water pump in the pump group malfunctions, causing the water flow velocity inside the pipe to decrease, the semi-circular plate, the load-bearing block, and the rotating shaft cause the turntable, the rectangular cylinder, and the switch to rotate downwards. This causes the adjacent arc-shaped head to enter the notch and make squeezing contact with the switch, thereby activating the switch. Under the control of the main body of the dispatcher, the corresponding water pump is shut down. This invention enables timely and precise mechanical dispatching of independent water pumps in the pump group, effectively reducing the probability of errors in pump group dispatching and ensuring dispatching effect and quality. This invention can obtain the optimal pump group start-up, shutdown, and speed regulation strategy to simultaneously optimize multiple conflicting objectives such as energy consumption, water supply pressure stability, and equipment wear.

[0016] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0017] Example 1: like Figures 1-9 As shown, this embodiment provides a water supply network pump group dispatching device, including: a dispatcher body 4 with a rectangular structure, a frame plate 41 attached to the right end of the dispatcher body 4 with its upper end hinged to the upper end of the dispatcher body 4, and the lower end of the frame plate 41 is detachably connected to the lower end of the dispatcher body 4. The frame plate 41 provides a mounting carrier for the transparent plate 42, and the transparent plate 42 located on the right side of the display part of the dispatcher body 4 is placed inside the frame plate 41. The transparent plate 42 protects the display part of the dispatcher body 4. Then, a cylinder 2 located between two annular plates 11 is installed on the left end of the dispatcher body 4. The cylinder 2 provides a mounting carrier for components such as the arc-shaped box 7. The tube 1 is placed on the left end of the cylinder 2. The tube 1 provides a mounting carrier for components such as the annular plate 11. The two annular plates 11 are symmetrically installed on the outer end of the tube 1, and the outer end face of the annular plate 11 coincides with the outer end face of the tube 1. The annular plates 11 are used to assist in the installation of the tube 1. Multiple grooves 12 are formed by inward indentation on the outer annular end face of both annular plates 11. The grooves 12 provide space for cutting the installation bolts when they cannot be disassembled normally. Multiple mounting holes 13 are formed by backward indentation on the front end face of both annular plates 11. The multiple mounting holes 13 pass through the multiple grooves 12 respectively. The mounting holes 13 provide a channel for the installation bolts to pass through the annular plates 11. A rotating shaft 5, which passes through the tube 1 and is located inside the cylinder 2, is rotatably connected to the right end of the tube 1. The rotating shaft 5 provides a mounting carrier for components such as the turntable 8. A semi-circular plate 6 located inside the tube 1 is installed on the annular end of the rotating shaft 5. The rotating shaft 5 is rotated by the semi-circular plate 6. A load-bearing block 61 with a triangular cross-section is placed on the lower rear end of the semi-circular plate 6. The semi-circular plate 6 is effectively rotated by the load-bearing block 61. The turntable 8 located inside the cylinder 2 is installed on the right end of the rotating shaft 5. The turntable 8 provides a mounting carrier for components such as the rectangular tube 81. A rectangular tube 81 is placed on the lower end of the turntable 8. The rectangular tube 81 provides installation space for the switch 82. The switch 82, whose lower end extends into the notch 83, is installed inside the rectangular tube 81. The switch 82 is electrically connected to the controller body 4. The switch 82 is used to shut off the corresponding water pump. The notch 83 is formed by protruding upward on the lower end of the rectangular tube 81. The notch 83 extends to the front and rear ends of the rectangular tube 81, respectively. The arc-shaped head 74 enters the rectangular tube 81 through the notch 83. The hollow tube 43 located on the left side of the main body 4 of the dispatcher is rotatably connected to the middle of the right end of the turntable 8. The hollow tube 43 protects the wires connecting the main body 4 of the dispatcher and the switch 82. Multiple fixing rods 44 with their outward ends connected to the inner wall of the cylinder 2 are equidistantly installed on the outer end of the hollow tube 43. The multiple fixing rods 44 and the hollow tube 43 work together to stably install the turntable 8. Then, the arc-shaped box 7 located on the lower rear side of the turntable 8 is installed on the inner wall of the cylinder 2. The arc-shaped box 7 provides an installation carrier for components such as the straight plate 73. Multiple straight plates 73, arranged in an arc shape and extending into the arc-shaped box 7, are equidistantly slidably connected to the upper end of the arc-shaped box 7. The straight plates 73 provide mounting carriers for components such as arc-shaped heads 74. Multiple arc-shaped heads 74, which cooperate with notches 83, are respectively set on the inner ends of multiple straight plates 73. The arc-shaped heads 74 cooperate with switches 82 and press the switches 82. Multiple rectangular plates 76, which are alternately arranged with partitions 72, are respectively set on the lower ends of multiple straight plates 73. The rectangular plates 76 provide mounting carriers for components such as magnetic plates 77. An electromagnet 71 with an arc-shaped cross-section is installed on the bottom of the inside of the arc-shaped box 7. Multiple magnetic plates 77 located on the upper side of the electromagnet 71 are respectively installed on the lower ends of multiple rectangular plates 76. The electromagnet 71 and the magnetic plates 77 are arranged to attract each other. The magnetic plates 77 and the electromagnet 71 work together to move the straight plate 73 and other components downward. Multiple partitions 72, whose other ends are connected to the top of the inside of the arc-shaped box 7, are installed at equal intervals on the upper end of the electromagnet 71. The multiple partitions 72 work together to divide the internal space of the arc-shaped box 7 into multiple protective cavities. Two first elastic members 75 located on both sides of the corresponding straight plate 73 are symmetrically installed on the upper end of the rectangular plates 76. The other end of the first elastic member 75 is connected to the top of the inside of the arc-shaped box 7. The two first elastic members 75 work together to return the straight plate 73 and other components to their original position. The first elastic member 75 can be a spring.

[0018] During construction, multiple water pumps are first installed in the pumping station to form a pump group, which is used to deliver water to the water supply network. Then, the front end of a pipe 1 is fitted together with the rear end of the outlet of a water pump. Then, multiple mounting bolts are sequentially passed through multiple mounting holes 13 on annular plate 11 and threaded with corresponding nuts, thereby connecting the pipe 1 to the outlet of the water pump. Then, the inlet of the water supply network is fitted together with the rear end of the pipe 1. Then, multiple mounting bolts are sequentially passed through mounting holes 13 on another annular plate 11 and threaded with corresponding nuts, thereby connecting the pipe 1 to the water supply network. Thus, the pipe 1 is used to connect the water pump to the water supply network. The same steps as above are followed to connect the pump group to the water supply network, thereby allowing the pumped water to flow and be used within the water supply network. When maintenance work such as replacement requires disassembling the pipe 1, if the threaded connection between the mounting bolt and the corresponding nut is stripped, making it impossible to disassemble the mounting bolt and the corresponding nut, the shank of the mounting bolt located in the groove 12 can be cut off to ensure the normal disassembly of the pipe 1.

[0019] Before use, sensors and other instruments installed on the water supply network are used to collect information data from the network. This data is then used to simulate an intelligent agent, which can be a water supply network management system commonly used in waterworks. The agent then interacts with the hydraulic simulation environment using conventional water supply system simulation methods, and autonomously analyzes the optimal pump start-up and shutdown procedures and speed control strategies. The relevant signals are then transmitted to the dispatcher main body 4 installed on each pump in the pump group, thereby completing the multi-objective collaborative operation of the pump group to optimize multiple conflicting objectives such as energy consumption, water supply pressure stability, and equipment wear. The dispatcher main body 4 integrates electronic components such as controllers, and conventional dispatching and control components in existing technologies can be used.

[0020] According to the relevant procedures, the dispatcher bodies 4 of the corresponding positions and quantities are operated, and the circuits of the corresponding electromagnets 71 are connected. Since the electromagnets 71 and magnetic plates 77 are arranged to attract each other, an attraction force is formed between the electromagnets 71 with the circuit connected and the corresponding magnetic plates 77. Under the action of the attraction force, the magnetic plates 77 move downward, thereby causing the corresponding rectangular plates 76, straight plates 73 and arc-shaped heads 74 to move downward to their limit positions. At the same time, the corresponding first elastic members 75 are stretched, thereby generating elastic force in the first elastic members 75, realizing the temporary contraction of components such as straight plates 73. This effectively reduces the probability of the corresponding water pumps in the pump group stopping due to factors such as contact between the switch 82 and the arc-shaped head 74 when the pump group starts to operate or the frequency is adjusted. It effectively reduces the probability of interference in the multi-target collaborative operation of the pump group and ensures that the pump group can move normally, effectively ensuring the dispatching effect and quality. Then the main body 4 of the dispatcher will start the corresponding water pumps in the pump group to transport water into the water supply network. At this time, the water pumped by the water pump will first enter the pipe cylinder 1, and then the water will be transported into the water supply network through the pipe cylinder 1. When the water flows in the pipe cylinder 1, the water flow will hit the semi-circular plate 6, causing the semi-circular plate 6 and the rotating shaft 5 to rotate, thereby causing the turntable 8, the rectangular cylinder 81 and the switch 82 to rotate. After the water pump has been running for a period of time, the water flow velocity in the pipe cylinder 1 will be stable. At this time, the semi-circular plate 6 will be in a stable position and will no longer rotate. Then the circuit of the electromagnet 71 will be disconnected by the control of the main body 4 of the dispatcher, thereby causing the attraction between the electromagnet 71 and the magnetic plate 77 to disappear. Under the action of the elastic force of the first elastic element 75, the rectangular plate 76, the straight plate 73 and the arc head 74 will return to their original positions inward. A pump group consists of multiple water pumps, all of which are connected to the water supply network. Before construction, the water plant will calculate the actual conditions of the water supply network and install the appropriate number of pumps based on the premise that the pump group can meet the water demand of the water supply network during peak water usage. Therefore, when the water supply network is in normal use, the water plant's management system will optimize the scheduling to ensure that an appropriate number of pumps in the pump group are in operation, while other pumps are not in operation.

[0021] When a pump in the pump group malfunctions, reducing the water flow velocity in the pipe cylinder 1 (e.g., a broken fan blade), but the pump motor is still running, this invention allows the rotating shaft 5 to rotate downwards under the weight of the semi-circular plate 6 and the load-bearing block 61. This causes the turntable 8, rectangular cylinder 81, and switch 82 to rotate downwards, resulting in the adjacent arc-shaped head 74 entering the notch 83 and making a squeezing contact with the switch 82. This activates the switch 82, causing the corresponding pump to stop under the control of the dispatcher body 4. Simultaneously, the dispatcher body 4 analyzes and compares the shutdown information with the optimal pump group start-up and shutdown procedure it has autonomously analyzed, and transmits the relevant information to the corresponding dispatcher body 4 on the non-operating pump. Then, the corresponding dispatcher body 4 initiates the start-up operation, ensuring the normal operation of the water supply network. This allows for timely dispatching of the pump group when a pump malfunctions. At the same time, the dispatcher body 4 on the malfunctioning pump issues a warning message to promptly repair the malfunctioning pump, ensuring the normal operation of the subsequent pump group. Furthermore, there is a predetermined distance between two adjacent arc-shaped heads 74, which ensures that when the water flow velocity in the pipe 1 changes within a normal range, the rotation angle of the turntable 8 is small, thus preventing the arc-shaped head 74 from making a squeezing contact with the switch 82. This allows the corresponding water pump to operate normally, enabling timely and precise mechanical scheduling of the independent water pumps in the pump group. This effectively reduces the probability of errors in the scheduling of the pump group and effectively ensures the scheduling effect and quality.

[0022] Example 2: like Figures 1-3 As shown, a circular box 3 rotatably connected to the left end of the rotating shaft 5 is installed on the left end of the tube 1, and the rotating shaft 5 extends into the circular box 3. The circular box 3 provides installation space for the limiting block 31, and the limiting block 31 located outside the rotating shaft 5 is installed on the top of the inside of the circular box 3. The cross-section of the limiting block 31 is arc-shaped. The movable plate 51 located inside the circular box 3 and below the limiting block 31 is set on the lower end of the rotating shaft 5.

[0023] First, using electromagnet 71 and multiple magnetic plates 77, the corresponding rectangular plate 76, straight plate 73, and arc head 74 are all moved downwards to their limit positions. Then, the main body 4 of the dispatcher will start the corresponding water pumps in the pump group to transport water into the water supply network. At the same time, the water pumped by the water pump will first enter the pipe cylinder 1, and then the water will be transported into the water supply network through the pipe cylinder 1. When the water flows in the pipe cylinder 1, the water flow will impact the semi-circular plate 6, causing the semi-circular plate 6 and the rotating shaft 5 to rotate, thereby causing the turntable 8, rectangular cylinder 81, and switch 82 to rotate. After the water pump has been running for a period of time, the water flow velocity in the pipe cylinder 1 is stable. At this time, the semi-circular plate 6 will be in a stable position and will no longer rotate. Then, the circuit of electromagnet 71 is disconnected, so that the attraction between electromagnet 71 and magnetic plate 77 disappears. Under the action of the elastic force of the first elastic element 75, the rectangular plate 76, straight plate 73, and arc head 74 return to their original positions inward. Furthermore, during the rotation of the rotating shaft 5, the movable plate 51 will rotate. At this time, the limiting block 31 will restrict the rotation angle of the movable plate 51, so that the semi-circular plate 6 is tilted when it is not rotating. This restricts the rotation angle of the semi-circular plate 6, effectively reducing the probability of reverse rotation of the semi-circular plate 6 due to factors such as water flow fluctuations, effectively reducing the probability of errors in the scheduling of the pump group, and effectively ensuring the scheduling effect and quality.

[0024] When a pump in the pump group malfunctions, reducing the water flow velocity in the pipe 1, the semi-circular plate 6, the load-bearing block 61, and the rotating shaft 5 cause the turntable 8, the rectangular cylinder 81, and the switch 82 to rotate downwards. This causes the adjacent arc-shaped head 74 to enter the notch 83 and make squeezing contact with the switch 82, thereby activating the switch 82. Under the control of the dispatcher body 4, the corresponding pump is shut down. At the same time, the dispatcher body 4 analyzes and compares the shutdown information with the multi-target collaborative program and transmits the relevant information to the corresponding dispatcher body 4 on the non-operating pump. Then, the corresponding dispatcher body 4 is started, thus ensuring the normal operation of the water supply network. This allows for timely dispatching of the pump group when a pump malfunctions. Simultaneously, the dispatcher body 4 on the malfunctioning pump issues a warning message to promptly repair the malfunctioning pump, ensuring the normal operation of the subsequent pump group.

[0025] Example 3: like Figure 10 and Figure 11 As shown, a screw 45 extending into a straight cylinder 46 is installed in the middle of the lower end of the dispatcher body 4, and the straight cylinder 46 is threaded to the lower end of the screw 45. The straight cylinder 46 and the screw 45 work together to adjust the distance between the dispatcher body 4 and the base plate 47 on the one hand, and to support the dispatcher body 4 on the other hand. The base plate 47 is then placed on the lower end of the straight cylinder 46, providing a mounting carrier for the straight cylinder 46. An annular rubber pad 431 located on the left side of the dispatcher body 4 is installed on the right end of the hollow tube 43. The annular rubber pad 431 protects the wire connecting the dispatcher body 4 and the switch 82. The mounting ring 48 located on the left side of the dispatcher body 4 and the right side of the fixing rod 44 is threaded onto the inner wall of the cylinder 2. The cylinder 2 provides a mounting carrier for components such as the light rod 485. The inner ring 482 located inside the mounting ring 48 is installed on the left end of the dispatcher body 4. The mounting ring 48 and the inner ring 482 are used together to make the cylinder 2 and the dispatcher body 4 detachably connected. Multiple smooth rods 485 passing through the inner ring 482 are equidistantly arranged on the inner wall of the mounting ring 48, and the smooth rods 485 are slidably connected to the inner ring 482. The smooth rods 485 guide the movement of the inner ring 482. Multiple circular plates 483 located inside the inner ring 482 are respectively installed on the inward ends of the multiple smooth rods 485. The circular plates 483 can compress or stretch the third elastic element 484. Multiple second elastic elements 481 located outside the multiple smooth rods 485 are equidistantly installed between the inner wall of the mounting ring 48 and the outer end of the inner ring 482. Multiple third elastic elements 484 located outside the multiple smooth rods 485 are equidistantly installed on the inner wall of the inner ring 482, and the inward ends of the multiple third elastic elements 484 are respectively set on the outward ends of the multiple circular plates 483. The second elastic elements 481 and the third elastic elements 484 are used together for vibration damping. Both the second elastic elements 481 and the third elastic elements 484 can be springs.

[0026] First, the mounting ring 48 is threaded into the cylinder 2, thereby installing the dispatcher body 4 onto the right end of the cylinder 2. Then, using the two annular plates 11, mounting holes 13, mounting bolts, and nuts, the pipe cylinder 1 is installed between the outlet of the corresponding water pump and the water supply network. Then, the straight cylinder 46 is manually rotated. Because the straight cylinder 46 is threaded to the screw 45, and both the outer end of the screw 45 and the inner wall of the straight cylinder 46 have threads, and the two threads are meshed with each other, the threads on the straight cylinder 46 will move downwards along the threads on the screw 45 during the rotation of the straight cylinder 46. Therefore, the straight cylinder 46 rotates and moves downwards at the same time, thereby causing the base plate 47 to move down and contact the ground, thereby supporting the dispatcher body 4 and increasing the installation stability of the dispatcher body 4. According to the relevant procedures, the dispatcher body 4 at the corresponding position and number will start the corresponding water pumps in the pump group, thereby pumping water into the water supply network. At the same time, the water pumped by the water pump will first enter the pipe cylinder 1, and then the water will be transported into the water supply network through the pipe cylinder 1. When the water flows in the pipe cylinder 1, the water flow will impact the semi-circular plate 6, thereby causing the semi-circular plate 6, the rotating shaft 5, the turntable 8, the rectangular cylinder 81 and the switch 82 to rotate. After the water pump has been running for a period of time, the water flow velocity in the pipe cylinder 1 will be stable. At this time, the semi-circular plate 6 will be in a stable position and will no longer rotate. When the water pumps in the pump group are working, they will generate vibrations. These vibrations will be transmitted through the pipe 1 to the cylinder 2 and the mounting ring 48. At this time, multiple smooth rods 485 will decompose and guide the vibration of the mounting ring 48 in multiple directions. With the assistance of the circular plate 483, the corresponding second elastic element 481 and third elastic element 484 will be compressed or stretched, thereby generating elastic force in the second elastic element 481 and third elastic element 484. The elastic force is used to cancel the vibration, thereby achieving vibration reduction protection for the dispatcher body 4. This effectively reduces the probability of damage to the dispatcher body 4 due to vibration when the pump group is working, and effectively ensures the dispatching effect and quality.
