Description

Technical Field

[0001] The present invention relates to the technical field of non-negative pressure water supply equipment, and in particular to a pipe network stacked non-negative pressure water supply equipment. Background Art

[0002] The municipal pipe network is interconnected with the user pipe network. Pumps on the user pipe network draw water from the municipal pipe network for user use. The pressure within the municipal pipe network remains constant. During low-peak water usage, when only a small number of users use water, the municipal pipe network provides a stable supply of water to users. During peak water usage, when a large number of users use water, the municipal pipe network's water supply to the user pipe network becomes insufficient. At this time, non-negative pressure water supply equipment is required to maintain stable water pressure.

[0003] The non-negative pressure water supply equipment consists of a simmer tank, a vacuum suppressor, a variable frequency speed regulating water pump unit, a pressure sensor, a variable frequency control cabinet, a backflow preventer, a disinfection device, a small flow pressure maintaining tank, etc. The water inlet pipe from the municipal pipeline is directly connected to the water inlet of the simmer tank. The water outlet of the simmer tank is connected to the pressure pump unit through the outlet pipe. The pressure pump unit is connected to the user's water pipe through a pipeline, thereby directly supplying water to the user's pipeline network. After a long time, the simmer tank is prone to scale accumulation, which affects the water quality. Therefore, the interior of the simmer tank needs to be cleaned regularly. After cleaning, the scale falls into the simmer tank. When the user uses water, the scale is discharged through the user's faucet along with the water in the simmer tank. Although this method can achieve the cleaning of scale in the simmer tank, the scale flowing in the outlet pipe can easily cause pollution to the outlet pipe. At the same time, the user needs to discharge a large amount of water to release clean water, which wastes water resources. Summary of the Invention

[0036] See also Figure 10-14 The blocking assembly shown in the figure includes a blocking plate 14 provided on one side of the feed port 12 and located inside the receiving chamber 9. A groove 15 is provided on one side of the blocking plate 14. A plurality of springs 16 are fixedly provided at equal distances inside the groove 15. The other end of the spring 16 is fixedly connected to the inner wall of the receiving chamber 9. Connecting rods 17 are fixed on both sides of the blocking plate 14. A sealing plug 18 matching the discharge port 11 is fixed on one side of the connecting rod 17.

[0037] See also Figure 10-14 The sealing assembly shown in the figure also includes sealing end plates 19 fixedly arranged at both ends of the arc plate 8, and sealing gaskets 20 are fixedly arranged on both sides of the sealing end plates and on both sides of the arc plate 8.

[0038] See also Figure 3-Figure 8 The unfolding assembly shown in the figure includes screw threads 21 fixedly arranged at both ends of the side walls of the shaft tube 3. The screw threads 21 are arranged at both ends of the shaft tube 3, and a moving block 22 is threadedly sleeved on the screw threads 21. Two movable rods 23 are provided between one side of the moving block 22 and the concave surface of the arc-shaped plate 8. Both ends of the movable rods 23 are connected to the moving block 22 and the arc-shaped plate 8 respectively through hinge shafts 24. A limit assembly is provided on one side of the arc-shaped plate 8.

[0039] When cleaning the scale inside the turbulence tank 1 in the pipe network superimposed non-negative pressure water supply equipment: first stop supplying water to the turbulence tank 1, and drain the water in the turbulence tank 1, collect it through the container when draining, and then fix the rotating rod 27 and the support block 2 through the fixing assembly, and the rotating shaft 28 and the rotating rod 27 are rotatably connected, so that the limiting assembly plays a limiting role on the arc plate 8. At this time, start the driving assembly to drive the water pipe 5 to rotate. Since the outer wall of the water pipe 5 and the inner wall of the shaft tube 3 are connected by the fixing block 39, the water pipe 5 can be rotated while driving the shaft tube 3 to rotate. The rotation of the shaft tube 3 can drive the moving block 22 to move. Since the arc plate 8 is limited by the limiting assembly, At this time, the rotation of the shaft tube 3 can drive the moving blocks 22 on the screw teeth 21 arranged in the positive and negative directions on the shaft tube 3 to move toward or in the opposite direction; when the moving blocks 22 move toward each other, the movable rod 23 is driven to move toward each other. Since both ends of the movable rod 23 are connected to the moving block 22 and the curved plate 8 through the hinge shaft 24, the flexibility of the rotation of the movable rod 23 can be achieved. When the movable rods 23 move toward each other, the curved plate 8 at the other end of the movable rod 23 can be pushed to expand the curved plate 8 along the radial direction of the shaft tube 3 to realize the expansion of the curved plate 8. After the curved plate 8 is expanded to the point where the scraper 13 on one side contacts the inner wall of the swirl pot 1, the start of the driving member is stopped at this time;

[0040] Then, the fixed position of the fixing assembly is changed so that the rotating rod 27 is not fixedly connected to the support block 2, and the rotating rod 27 is fixedly connected to the rotating shaft 28 in the driving assembly, so that the fixed connection between the rotating rod 27 and the rotating shaft 28 is realized. Then, the driving assembly is started to drive the rotating shaft 28 to rotate. The rotating shaft 28 rotates and the rotating rod 27 is driven to rotate at the same time, so that the limiting assembly can be driven to rotate synchronously. Since one end of the rotating shaft 28 is fixedly connected to the water pipe 5, the water pipe 5 can be driven to rotate, and the rotation of the water pipe 5 drives the shaft pipe 3 to rotate. At this time, the limiting assembly no longer limits the arc plate 8, and the arc plate 8 is driven to rotate synchronously while the shaft pipe 3 rotates.

[0041] When the curved plate 8 rotates, the scraper 13 on one side contacts the inner wall of the swirl pot 1, so that the scraper 13 can scrape off the scale on the inner wall of the swirl pot 1, and the scraped water pipe 5 will slide into the storage chamber 9 inside the curved plate 8 through the feed port 12 on the curved plate 8 on one side of the scraper 13, so as to collect the scale scraped off from the inside of the swirl pot 1, and the scale falling into the storage chamber 9 slides into the two sides of the storage chamber 9 through one end of the baffle 42 inside the storage chamber 9, so as to collect the scale, and prevent the scale inside the storage chamber 9 from flowing out in the opposite direction through the feed port 12 when the curved plate 8 is rotated to an inclined position or a vertical position. By fixing a baffle 42 on one side of the inner wall of the storage chamber 9, the reverse flow of the scale can be effectively reduced, thereby increasing the safety of scale collection.

[0042] After the scale on the inner wall of the turbulence tank 1 is scraped and cleaned, the driving assembly is stopped at this time, and the shaft tube 3 stops rotating. Then, the rotating rod 27 in the fixed assembly is fixedly connected to the supporting block 2. At this time, the rotating rod 27 and the rotating shaft 28 become a rotating connection again, and the limiting assembly plays a limiting role for the curved plate 8 again, and the shaft tube 3 is rotated in the opposite direction, driving the moving block 22 on the screw thread 21 to move in the opposite direction, and the moving block 22 pulls the curved plate 8 in the direction close to the shaft tube 3 through the movable rod 23, so that the sealing end plates 19 at both ends of the curved plate 8 are squeezed and extruded between the outer wall of the shaft tube 3. At this time, the rotation of the shaft tube 3 is stopped, and after the sealing end plates 19 are squeezed out from the outer wall of the shaft tube 3, the sealing gaskets 20 on both sides of the curved plate 8 are squeezed out from the sealing gaskets 20 on the adjacent curved plates 8, realizing the sealing between the ends of the two connected curved plates 8, realizing the formation of a hollow cylinder sleeve on the outer side of the shaft tube 3 between the multiple curved plates 8, realizing the protection and sealing of the shaft tube 3;

[0043] When the arc plate 8 is formed into a hollow cylinder and is sleeved on the shaft tube 3, the discharge pipe 4 on the shaft tube 3 is inserted into the discharge port 11 on the concave side of the arc plate 8, thereby realizing the communication between the receiving chamber 9 and the shaft tube 3. At the same time, the top pipe 6 is inserted into the insertion hole 10 on the concave side of the arc plate 8, and the top pipe 6 is inserted into the insertion hole 10 and extends toward the inside of the receiving chamber 9 to push the blocking plate 14. The blocking plate 14 is pushed to move the blocking plate 14 toward the side of the feed port 12, thereby realizing the blocking of the feed port 12 by the blocking plate 14. At this time, the spring 16 in the groove 15 on one side of the blocking plate 14 is in a stretched state, so that the spring 16 reserves elastic potential energy. When the arc plate 8 is unfolded, the blocking plate 14 is pulled back to its original position to make the feed port 12 When it is opened again, the top pipe 6 is inserted into the socket 10, so that the water outlet 7 at the end of the top pipe 6 can be connected to the receiving chamber 9. At this time, one end of the water pipe 5 is connected to one end of the water supply pump, and the other end of the water supply pump is placed in a container connected to the stabilizing tank 1 to discharge water. The water supply pump is started to transport the water in the receiving container to the water pipe 5, and then the water flows into the top pipe 6 from the water pipe 5, and then the water outlet 7 is opened on the side wall of the end of the top pipe 6 to be discharged into the receiving chamber 9, so as to flush the inside of the receiving chamber 9. When installing the top pipe 6, the top pipe 6 is located in the middle of the arc plate 8, and the discharge port 11 is located on both sides of the arc plate 8. At this time, when water is injected into the receiving chamber 9, the flushing can be achieved. The storage chamber 9 plays a role of flushing. At the same time, the scale and water inside the storage chamber 9 will flow into the inside of the discharge pipe 4 into the shaft tube 3 through the discharge port 11, and then be discharged through the discharge pipe 41 at one end of the shaft tube 3, so as to achieve the effect of flushing and discharging the scale in the swirl tank 1, and realize the convenience of cleaning the scale on the inner wall of the swirl tank 1. When the scale inside the storage chamber 9 is flushed, water can be injected into the swirl tank 1 from the municipal pipe network for the use of the user, avoiding the influence of water outage on the use of the user, and effectively shortening the time for cleaning the scale on the inner wall of the swirl tank 1. The operation is simple and can realize the convenience of cleaning the scale on the inner wall of the swirl tank 1, and can realize the convenience of cleaning the curved plate 8. The scraper 13 on one side can be used repeatedly to avoid repeated disassembly and assembly, which effectively reduces the labor intensity of the staff. When scraping off the scale on the inner wall of the turbulence tank 1, the scale can be collected to reduce the scale falling into the turbulence tank 1 and causing pollution to the water injected again. The contaminated water is provided to the user and the user needs to discharge the contaminated water before it can be used. It can effectively reduce the user's discharge of water contaminated by scale and reduce the waste of water resources. At the same time, it avoids scale entering the user's water supply pipe and causing pollution to the user's water supply pipe, effectively improving the safety of the user's water supply pipe. This operation can effectively reduce the pollution of water re-injected into the turbulence tank 1, while reducing the waste of water resources and improving the safety of the user's water use.

[0046] See also Figure 3-Figure 5 and Figure 9 The limiting assembly shown in the figure includes a limiting block 25 fixed to one end of the arc plate 8 and located on one side of the sealing end plate 19. The limiting block 25 is slidably arranged inside the guide rail 26. The guide rail 26 is fixed to the side wall of one end of the rotating rod 27. One end of the rotating rod 27 is rotatably connected to one end of the shaft tube 3. One end of the rotating rod 27 passes through the swirl pot 1 and extends outward through the fixed assembly to be connected to the support block 2.

[0047] See also Figure 1-Figure 5 and Figure 7-Figure 9 The driving assembly shown in the figure includes a rotating shaft 28 fixed to one end of the water pipe 5, and one end of the rotating shaft 28 passes through the shaft tube 3 and the rotating rod 27 in sequence and extends to the outside of the swirl pot 1 to be connected to the output end of the motor 29.

A third threaded hole 33 matching the second threaded hole 32 is provided on the side wall of the end block 31 at equal distances, and a locking bolt 34 is provided on the internal thread of the second threaded hole 32.

[0049] In this embodiment, a limiting component is provided on one side of the arc-shaped plate 8, which can limit the arc-shaped plate 8 when the expansion component is expanded. When the expansion component needs to be expanded, the fixing component at one end of the rotating rod 27 is first fixedly connected to the support block, and the second threaded hole 32 on the end block 31 is connected to the support block 2 through a locking bolt 34 to achieve a fixing effect between the rotating rod 27 and the swirl pot 1;

[0050] Then rotate the shaft tube 3 in the expansion assembly. Since the shaft tube 3 and the water pipe 5 are connected by a fixed block 39, rotating the water pipe 5 can drive the shaft tube 3 to rotate. Since the shaft tube 3 is provided with positive and negative screw teeth 21, and the positive and negative screw teeth 21 are threadedly connected to the moving block 22, it can be achieved that when the shaft tube 3 rotates, the arc plate 8 is driven to rotate. A limit block 25 is provided at one end of the arc plate 8, and the limit block 25 is slidably arranged in the guide rail 26, and the guide rail 26 is fixedly arranged on the rotating rod 27. At this time, the guide rail 26 can be fixed. The fixed function is to prevent the shaft tube 3 from driving the synchronous rotation of the curved plate 8 through the moving block 22 and the movable rod 23 when the shaft tube 3 rotates, so that the curved plate 8 is limited, so that the moving block 22 threadedly connected to the screw thread 21 on the shaft tube 3 moves. Due to the positive and negative settings of the screw threads 21 at both ends of the shaft tube 3, the moving blocks 22 can be driven to move toward or in the opposite direction when the shaft tube 3 rotates, so that the curved plate 8 can be expanded and retracted, and the addition of the limiting component is realized, which increases the stability of the expansion and retraction of the curved plate 8.

[0051] A driving assembly is provided at one end of the water pipe 5, which can realize the rotation of the water pipe 5 by the motor 29, thereby driving the shaft tube 3 to rotate, realizing the convenience of expanding and retracting the curved plate 8 for the rotation of the shaft tube 3.
