Description

Technical Field

[0001] The invention relates to the technical field of water supply equipment, in particular to an internal and external exchange device of an underground integrated pressure regulating pump station for municipal water supply. Background Art

[0002] Water supply equipment is mainly used in areas where the pressure of the municipal pipeline network cannot meet the water supply capacity. Water supply refers to the storage and pressurization of urban public water supply or self-built facility water supply by units or individuals. It is necessary to build a water supply tank to complete the storage of municipal water, so as to achieve active water replenishment and pressure regulation during the peak period of municipal pipeline water use. The internal and external exchange of water supply to the water supply tank during the low-peak period of municipal pipeline water use ensures the stability of the water pressure of the municipal pipeline network and avoids the interference of unstable water pressure on water use.

[0003] A secondary water supply device is disclosed in the patent application with reference publication number CN112049195A. The water supply device utilizes the water level changes in the stabilizing tank at different time periods to generate an air source. No external air supply device is required. When there is insufficient air in the stabilizing tank, the air supply can be automatically turned on. When the air is sufficient, the air supply can be automatically turned off. No manual monitoring is required, and the degree of automation is high.

[0004] The above-mentioned water supply equipment can ensure the stability of water use by actively pressurizing municipal water through a flow stabilization tank. Such water supply equipment needs to be equipped with a water supply tank to actively regulate the pressure of municipal water. However, the water supply tank of the water supply equipment is not managed in a partitioned manner, so that the water sources that enter the water supply tank successively will mix with each other and cannot be accurately controlled. Therefore, the storage time of municipal water in the water supply tank is uncontrollable. The long water storage time and the long water age also affect the water quality.

[0005] At the same time, the water supply tank of the water supply equipment cannot complete the active pressurization action according to the weight of the municipal water itself, and the weight of the municipal water cannot be divided into zones for reasonable distribution and use. It is necessary to rely on the water pump group to complete the pressure regulation work, which increases the load of the water pump group, shortens the service life of the water pump group, and increases the cost investment in municipal water pressure regulation.

[0038] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0039] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0040] Embodiment 1: The present invention provides a technical solution: Figures 1 to 14As shown, the internal and external exchange device of the municipal water supply underground integrated pressure regulating pump station includes a water supply tank 1, the top of which is open in design, a municipal pipe network 2 is set up on one side of the water supply tank 1, a water pump group 3 is installed between the municipal pipe network 2 and the water supply tank 1, an inlet pipe 4 and an outlet pipe 5 are symmetrically installed on one side of the municipal pipe network 2, the inlet pipe 4 is connected with the output end of the water pump group 3, and an inlet pipe 6 and an outlet pipe 7 are respectively installed on both sides of the water supply tank 1, the inlet pipe 6 is located at the top of one side of the water supply tank 1, and the outlet pipe 7 is located at the bottom of one side of the water supply tank 1, the internal and external exchange action is completed through the cooperation of the water supply tank 1, the inlet pipe 6, the outlet pipe 7 and the municipal pipe network 2, and the inlet pipe 6 is connected with the outlet pipe 5 through a flange, the outlet pipe 7 is connected with the input end of the water pump group 3, and is installed at the ends of the inlet pipe 4 and the outlet pipe 5. There is a flow controller 8, through which the flow control of the inlet pipe 4 and the outlet pipe 5 is completed. A plurality of partition plates 9 are installed at intervals in the water supply tank 1. The plurality of partition plates 9 divide the water supply tank 1 into a plurality of partition spaces 10. A top cover 11 is removably and sealably installed on the top of the plurality of partition spaces 10. The top of the water supply tank 1 is sealed by the plurality of top covers 11. A pressure regulating mechanism is installed in the plurality of partition spaces 10. The pressure regulating mechanism is used to actively regulate the water source in each partition space 10. The pressure regulating mechanism is composed of an opening and closing component and a reset component. The opening and closing component can complete dynamic upper and lower stratification work in each partition space 10, and reasonably distributes the water source in each partition space 10 through the opening and closing component. The reset component is used to drive the opening and closing component to complete the reset work;

[0041] It is worth noting that when the water source in the partition space 10 is pressure-regulated, a pressure-regulating mechanism is provided to first adjust the support plate 15 to the middle position in the partition space 10. This position can be freely adjusted by technicians according to usage requirements. Since the buoyancy member 18 is in an open state in the diversion area 16 due to gravity at this time, the water source that subsequently enters the partition space 10 is sent to the bottom of the partition space 10 through the diversion area 16. When the liquid level in the partition space 10 rises, the water source contacts the buoyancy member 18. The buoyancy member 18 senses the buoyancy of the water source and moves up synchronously until the buoyancy member 18 is reset to the diversion area 16 to complete the blockage. At this time, the locking component locks the support plate 15. The water source that is subsequently introduced enters the partition space 10 and is located above the support plate 15, which plays a role of separation. The water outlet pipe 7 delivers the water source at the bottom of the partition space 10. As the water source at the bottom of the partition space 10 decreases, the support plate 15 gradually moves downward under the gravity pressure of the water source at the top of the partition space 10. Therefore, the active pressurization operation of the water source at the top on the water source at the bottom is completed in the partition space 10, so that the water source at the bottom continues to gain pressure, which is conducive to the rapid discharge of the water source. At the same time, the load of the water pump group 3 is reduced, and the life of the equipment is extended. After the support plate 15 moves down to the predetermined position, the locking component is automatically unlocked, so that the buoyancy member 18 is opened again. At this time, the liquid above the support plate 15 is again introduced into the bottom of the support plate 15 through the guide area 16. At the same time, the support plate 15 is synchronously moved up and pulled to the predetermined position by the reset component. Repeating the above actions can complete the active pressurization work in the partition space 10.

[0042] In the embodiment of the present invention, a plurality of branch pipes 12 are connected to the water inlet pipe 6 and the water outlet pipe 7 on the side facing the water supply tank 1, and the plurality of branch pipes 12 are connected to the water supply tank 1. The plurality of branch pipes 12 on the water inlet pipe 6 and the water outlet pipe 7 are respectively connected to the plurality of partitioned spaces 10, and control valves for controlling the opening and closing thereof are installed on the plurality of branch pipes 12. An air supply pipe 13 is provided on the plurality of partitioned spaces 10, and the air supply pipe 13 passes through the top cover 11 and the opening and closing assembly. The air supply pipe 13 slides through the support plate 15 correspondingly, and a plurality of air holes are evenly opened on one side of the air supply pipe 13, and the balance control of the air pressure in the partitioned space 10 is completed through the plurality of air holes, and the air supply pipe 13 is connected to the external air pressure control device;

[0043] It should be noted that: when performing internal and external exchange: when water consumption is low, the flow controller 8 of the outlet pipe 5 is turned on, and the water source in the municipal pipe network 2 is stored in the water supply tank 1. When water consumption is peak, the flow controller 8 of the inlet pipe 4 is turned on, and the water pump group 3 is turned on, and the water source stored in the partition space 10 is sent to the municipal pipe network 2 through the outlet pipe 7 to complete the pressure regulation operation, so that the water consumption of the municipal pipe network 2 remains stable, the pressure of the municipal pipe network 2 is relieved, the water consumption is balanced, and the water pressure during peak periods is guaranteed;

[0044] When performing zoned water inlet and outlet: the water supply tank 1 is divided into multiple zoned spaces 10 through the zone plate 9, and the multiple branches 12 on the water inlet pipe 6 and the water outlet pipe 7 are respectively connected to the top and the bottom of each zoned space 10, so that the water source can be quickly and accurately delivered to and delivered to each zoned space 10, and the water sources stored in the water supply tank 1 at different periods can be actively zoned to avoid the problem of mixing of water sources in different periods in the water supply tank 1. Subsequently, the water sources in the corresponding zoned spaces 10 will be discharged in the order of storage according to the pressure regulation requirements. Through the cooperation of the zoned spaces 10, the problems of long water storage time, high water age and affecting water quality can be avoided.

[0045] Among them, electrical components such as the water pump group 3, flow controller 8, waterproof cylinder 27, electromagnet 28 and reduction motor 24 are all connected to switches through wires, and the switches are electrically connected to the controller. The specific structure of the controller is not limited, thereby completing the overall control of the equipment.

[0046] Embodiment 2: Based on the opening and closing assembly provided in Embodiment 1, this embodiment provides a further technical solution for the opening and closing assembly.

[0047] like Fig. 9 and Fig.10 As shown, the opening and closing component includes a slide 14 symmetrically opened on both sides of the inner wall of the partition space 10, a support plate 15 is slidably installed in the partition space 10, and a stopper is detachably installed in the partition space 10. The position of the stopper can be fine-tuned up and down. The stopper is used to limit the extreme position of the support plate 15, so that the support plate 15 can stably rise to a predetermined height in the partition space 10. The two ends of the support plate 15 are correspondingly slidably engaged in the slide 14, a guide area 16 is opened through the middle position of the support plate 15, and a guide area 17 is recessed in the middle position of the lower surface of the support plate 15. The guide area 17 is arranged in coordination with the guide area 16, and the size of the guide area 17 is larger than the guide area 16. A sliding seal is installed at the bottom of the guide area 16 A buoyancy member 18 is installed, which is normally hidden in the guide area 17 to block the guide area 16, and limit rods 19 are installed at the four corners of the buoyancy member 18. The top of the limit rod 19 slides through the support plate 15 accordingly, and a limit head is installed on the top of multiple limit rods 19. The limit head is used to actively limit the buoyancy member 18. The buoyancy member 18 includes a buoyancy frame 181. The buoyancy frame 181 completes the opening and closing operation of the guide area 16 under the guidance of the limit rod 19. The buoyancy frame 181 is connected to the bottom of multiple limit rods 19 on all sides, and a floating plate 182 is hidden at the bottom of the buoyancy frame 181. The blocking of the guide area 16 is completed by the cooperation of the floating plate 182 and the buoyancy frame 181;

[0048] In the embodiment of the present invention, the reset assembly includes a fixed seat 20 installed on the top cover 11, an electromagnetic clutch 21 is installed on one side of the fixed seat 20, a reel 22 is rotatably installed on the other side of the fixed seat 20, a steel rope 23 is wound around the outside of the reel 22, the reel 22 is transmission-connected with the electromagnetic clutch 21, and a reduction motor 24 is installed on one side of the fixed seat 20, the reduction motor 24 is transmission-connected with the electromagnetic clutch 21, and the power connection and disconnection operation between the reduction motor 24 and the reel 22 is completed through the electromagnetic clutch 21, and a lifting frame 25 is installed on the upper surface of the support plate 15, the bottom of the steel rope 23 is detachably fixedly connected to the lifting frame 25, and a through hole matching the steel rope 23 is opened on the top cover 11, and an adsorption iron plate 26 is installed at the middle position of the top of the buoyancy frame 181, a waterproof cylinder 27 is installed on the lifting frame 25, and an electromagnet 28 is installed at the output end of the waterproof cylinder 27, and the electromagnet 28 is arranged in cooperation with the adsorption iron plate 26;

[0049] It is worth noting that: when resetting the opening and closing component, a reset component is provided. When the water source liquid level below the partition space 10 reaches a predetermined height, the electromagnetic clutch 21 is disconnected. At this time, the steel rope 23 can be released freely. At this time, the weight of the water source above the support plate 15 is applied to the water source below through the support plate 15. After the subsequent water pump group 3 is turned on, the support plate 15 gradually moves down to complete the pressurization. When resetting, it is only necessary to turn on the electromagnetic clutch 21, and the reduction motor 24 acts on the reel 22 to wind the steel rope 23, and pull the support plate 15 up to the predetermined height, and then complete the resetting work.

[0050] Embodiment 3: Based on the locking assembly provided in Embodiment 1, this embodiment provides a further technical solution of the locking assembly.

[0051] like Figures 11 to 14 As shown, locking components are provided at the four corners of the guide area 16 on the support plate 15, and the four locking components all include a locking arm 29 installed on one side of the limit rod 19. The height of the locking arm 29 is higher than the limit position of the limit rod 19, so that when the buoyancy member 18 is opened to the maximum opening and closing degree, the locking arm 29 is still in contact with the sliding member 31. The locking arm 29 slides through the support plate 15, and a locking seat 30 is installed on the upper surface of the support plate 15 on one side of the locking arm 29. The two sides of the locking seat 30 are through-opening design. A slide 31 is slidably provided on the locking seat 30, and a first inclined surface is provided on the side of the slide 31 facing the locking arm 29, and a slide 32 is installed on the side of the locking arm 29 away from the locking arm 29, and the tail of the slide 31 is correspondingly slidably engaged with the slide 32, and a return spring 33 is installed between the slide 32 and the tail of the slide 31, and a locking groove 34 is concavely provided on the side of the locking arm 29 facing the locking seat 30, when the buoyancy member 18 blocks the guide area 16, the slide 31 is correspondingly inserted into the locking groove 34 to complete the locking;

[0052] It is worth mentioning that when the buoyancy member 18 is locked, a locking assembly is provided. When the liquid level below the support plate 15 gradually rises, the buoyancy member 18 drives the locking arm 29 to follow and move upward, and is guided by the limit rod 19. Since the locking arm 29 is in contact with the side wall of the slide 31 for a long time, when the buoyancy member 18 rises, the slide 31 gradually approaches the locking groove 34 on the locking arm 29 until the buoyancy member 18 blocks the diversion area 16. At this time, the slide 31 is inserted into the locking groove 34 to complete the locking, so that the support plate 15 forms a whole. After the subsequent support plate 15 moves down to a predetermined position in the partition space 10, the weight of the support plate 15 itself and the weight of the water source make the sensing plate contact with the bottom of the partition space 10, push the trigger arm 37 to move upward and compress the trigger spring 38. When the arm 37 moves upward, the second inclined surface 39 on it cooperates with the first wedge block 36 to contact and squeeze, driving the slide 31 to shrink and move out of the locking groove 34 to complete unlocking. At this time, the buoyancy member 18 is subjected to the pressure of the water source and the weight of the buoyancy member 18 itself, so that the diversion area 16 is still in an open state. Until the support plate 15 is reset to a predetermined height, the water source liquid level under the support plate 15 rises, and the buoyancy member 18 is pushed up again to complete the locking. In order to ensure the stable operation of the locking component, the waterproof cylinder 27 is started to push the electromagnet 28 to contact the adsorption iron plate 26. Subsequently, the adsorption iron plate 26 is adsorbed and fixed by the electromagnet 28, and the buoyancy member 18 is pulled up and reset by the waterproof cylinder 27 to block the diversion area 16, thereby providing different control methods and enriching the operation space of technicians.

[0053] Among them, an open area 35 is opened through the slide 31, and a wedge block 36 is installed on the side of the open area 35 away from the locking arm 29. A trigger arm 37 is slidably penetrated on the locking seat 30. The moving length of the trigger arm 37 is greater than the moving length of the locking arm 29. After the trigger arm 37 touches the bottom, the slide 31 is moved out of the locking groove 34 in advance through the trigger arm 37, and the locking arm 29 of the subsequent buoyancy member 18 can be smoothly separated from the slide 31 to prevent the slide 31 from being inserted into the locking groove 34 again to affect the opening of the buoyancy member 18. The top of the trigger arm 37 slides correspondingly to extend into the open area 35, and the bottom of the trigger arm 37 slides The support plate 15 is provided, a sensing plate is installed at the bottom of the trigger arm 37, a trigger spring 38 is installed between the lower surface of the support plate 15 and the sensing plate, and the trigger spring 38 is correspondingly sleeved on the outside of the trigger arm 37, and a second inclined surface 39 is provided on the top of the trigger arm 37, and the second inclined surface 39 is provided in cooperation with the first wedge block 36, and a through hole is provided on the top of the locking seat 30 to cooperate with the trigger arm 37, and a baffle is installed on one side of the trigger arm 37 in the locking seat 30, and the baffle is used to limit the position of the trigger arm 37, and the baffle can slide into the open area 35, and a through hole is provided on the locking seat 30 to cooperate with the baffle;

[0054] In the embodiment of the present invention, two friction components are symmetrically arranged on both sides of the guide area 16 at the bottom of the support plate 15, and the two friction components include a vertical arm 40 installed in the middle position of one side of the guide area 17, and a cross bar 41 is slidably penetrated on the vertical arm 40, and a third inclined surface 42 is arranged at the tail of the cross bar 41, and a second wedge block 43 is installed in the middle position of one side of the buoyancy frame 181, and the second wedge block 43 is arranged in cooperation with the third inclined surface 42, and a concave seat 44 is installed on the side of the cross bar 41 away from the second wedge block 43, and a friction member 45 is installed in the concave seat 44, and a pulling member is installed between the concave seat 44 and the vertical arm 40. Spring 46, the pulling spring 46 is correspondingly sleeved on the outside of the cross bar 41, and the concave seat 44 is pulled toward the second wedge block 43 to reset by the pulling spring 46. Under normal conditions, the friction member 45 is separated from the inner wall of the partition space 10 and does not contact. When the buoyancy member 18 is separated from the guide area 16, the friction member 45 is driven to frictionally contact with the inner wall of the partition space 10, so that the buoyancy member 18 obtains a stable open state. The friction member 45 includes a mounting plate 451 that is slidably engaged in the concave seat 44, and a friction plate 452 is detachably mounted on the mounting plate 451, and two push springs 453 are installed between the mounting plate 451 and the concave seat 44;

[0055] It is worth noting that: when providing friction to the buoyancy member 18, by providing a friction assembly, when the support plate 15 moves downward, the friction member 45 is separated from the inner wall of the partition space 10. When the buoyancy member 18 is separated from the support plate 15, the buoyancy member 18 moves downward and is guided by the No. 2 wedge block 43 and the No. 3 inclined surface 42, pushing the cross bar 41 and the friction member 45 forward to frictionally contact with the inner wall of the partition space 10, so that the buoyancy member 18 remains stable. At the same time, in the subsequent upward reset of the support plate 15 and the buoyancy member 18, the friction force provided by the friction member 45 keeps the buoyancy member 18 in a stable open state, and the water source can be smoothly sent to the bottom of the support plate 15 through the diversion area 16 for recycling. The friction plate 452 on the friction member 45 is actively pressurized by pushing the spring 453, so that the friction plate 452 carries pressure and contacts with the inner wall of the partition space 10, thereby enhancing the friction effect. At the same time, it can actively compensate for the wear of the friction plate 452, thereby improving the smooth operation of the equipment.

[0056] The present invention provides an internal and external exchange device of an underground integrated pressure regulating pump station for municipal water supply, and the specific working principle is as follows: first, the water supply tank 1 and other equipment are concealed and installed underground, and the greening that is planted and coordinated with the environment is covered on the surface, which is beautiful as a whole, does not affect the municipal greening area, and reduces the occupied area. In subsequent operation, under the peak water use condition of the municipal pipe network 2, the water source stored in the partition space 10 is sent to the municipal pipe network 2 through the water pump group 3 to complete the pressure regulation work. Under the low-peak water use condition of the municipal pipe network 2, the water source in the municipal pipe network 2 is transported to the partition space 10 for storage, so as to complete the internal and external exchange work under the cooperation of the water supply tank 1, the water inlet pipe 6, the water outlet pipe 7 and the municipal pipe network 2, relieve the pressure of the municipal pipe network 2, meet the water use balance, complete the peak water replenishment and low-peak water storage work, ensure the peak water pressure, and complete the pressure regulation of the municipal pipe network 2;

[0057] By dividing the water supply tank 1 into a plurality of partition spaces 10, during the low-peak water storage process, the water sources stored in the water supply tank 1 at different periods can be actively partitioned to avoid the problem of water sources of different periods mixing in the water supply tank 1. Subsequently, the water sources in the corresponding partition spaces 10 are discharged in the order of storage according to the pressure regulation requirements. Through the cooperation of the partition spaces 10, the water sources in the water supply tank 1 are introduced into and led out of the water supply tank 1 in the order of priority, thereby avoiding the problem of long water storage time, high water age, and affecting water quality.

[0058] In addition, a pressure regulating mechanism is added in each partition space 10. Through the dynamic opening and closing of the opening and closing component in the partition space 10, the partition space 10 is divided into two upper and lower spaces by the opening and closing component. When the partition space 10 is subsequently continuously stored with water, the weight of the water source is used to act on the opening and closing component to complete active pressurization, so that the water source below the partition space 10 obtains a pressurized effect, which is beneficial to the subsequent pressure regulation work in the subsequent partition space 10. At the same time, the load of the water pump group 3 is reduced, the difficulty of pressure regulation is reduced, and the life of the equipment is extended. In addition, the pressure regulating mechanism can complete active resetting and repeat the pressurization action, so that the water supply equipment runs smoothly as a whole, with a simple structure and stable operation.
