[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The present invention has a secondary water pipe, a tertiary water pipe and a steady flow water tank, which can directly use the pressure in the municipal tap water network to supply water to high-rise users, thereby saving energy. At the same time, by arranging a high-efficiency energy-saving submersible pump, when the water consumption of users in the surrounding area is large, the pressure in the municipal tap water network is relatively small. When the water pressure is not enough to support the water level in the output water pipe to the height of the user's floor, the high-efficiency energy-saving submersible pump will be started to increase the water pressure in the output water pipe to supply water to high-rise residents.

When the water pressure in the municipal tap water network further decreases with the increase of water consumption, resulting in the water intake into the steady flow water tank in the tertiary water pipe being less than the water output discharged into the output water pipe through the high-efficiency and energy-saving submersible pump, the water pressure sensor will detect the negative pressure generated in the steady flow water tank. At this time, the water in the water storage tank will be used as a supplement to the water source in the tertiary water pipe to meet the water demand of high-level users, thereby improving the water use stability of high-level users. In addition, by using the water source inside the water storage tank in time, the storage time of the tap water inside the water storage tank can be reduced, thereby reducing the degradation of water quality caused by long-term storage.

[0020] 3. The present invention has a first cleaning rack and a second cleaning rack that can be raised and lowered, and the first cleaning rack and the second cleaning rack can be used to clean the attachments on the inner wall of the steady flow water tank, thereby improving the cleanliness of the water storage equipment.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] The following is combined with Figure 1 - Figure 8 The specific implementation modes of the present invention are described in further detail.

[0032] Depend on Figure 1 - Figure 8 In order to achieve the purpose of utilizing the water pressure in the municipal water pipe for high-rise water supply, the present invention comprises: a main water network 1, which is used to connect to the municipal tap water network to supply water to the system, and the ends of the main water network 1 are connected in sequence with a secondary water pipe 2 and a tertiary water pipe 3;

[0033] The output water pipe 37 is used to connect the user's household water pipe. The water inlet end of the output water pipe 37 is connected to the high-efficiency energy-saving pump group 4 and the steady flow water tank 5 through a tee. The input end of the steady flow water tank 5 is connected to the end of the tertiary water pipe 3. The middle of the tertiary water pipe 3 is connected to a connecting pipe 6, and a one-way valve 7 is provided in the middle of the connecting pipe 6. An electric valve 40 is provided in the middle of the secondary water pipe 2.

[0034] The middle of the secondary water pipe 2 is connected to a water storage tank 8, and the output end of the water storage tank 8 is connected to the water inlet end of the connecting pipe 6 and the water inlet end of the high-efficiency energy-saving pump group 4 through a tee.

[0035] A high-efficiency energy-saving submersible pump 9 is provided inside the steady-flow water tank 5, and a water pressure sensor 10 is provided on the top of the inner side of the steady-flow water tank 5, and the water pressure sensor 10 is communicatively connected with the electric valve 40;

[0036] A first cleaning frame 11 and a second cleaning frame 12 that can move up and down are provided inside the steady flow water tank 5;

[0037] It should be noted that there is water pressure in the municipal water pipe network, and the water level in the output water pipe 37 can be sent to a height of 30-40m by the water pressure. The high-efficiency energy-saving submersible pump 9 is a prior art. When there is water pressure in the steady flow water tank 5, water can be delivered to the output water pipe 37 by the water pressure even when the high-efficiency energy-saving submersible pump 9 is not started. The water pressure sensor 10 and the electric valve 40 are both prior art and will not be described in detail here.

[0038] When in use, the high-efficiency energy-saving pump group 4 is used as a pressurizing device for the original user's household water pipe. It lifts the water in the water tank 8 to a suitable height to meet the water needs of high-rise users. On the basis of keeping the original water supply line of the high-efficiency energy-saving pump group 4 unchanged, the connecting pipe 6, the tertiary water pipe 3, and the steady flow water tank 5 are connected at the end of the secondary water pipe 2, that is, the high-efficiency energy-saving pump group 4 is connected in parallel through the connecting pipe 6, the tertiary water pipe 3 and the steady flow water tank 5, and then the output water pipe 37 is supplied with water through the steady flow water tank 5. The high-efficiency energy-saving pump group 4 is used as a standby water supply equipment. It should be noted that under the action of the one-way valve 7, the water in the water tank 8 can only flow out of the water tank 8 in one direction through the one-way valve 7, and cannot enter the water tank 8 through the one-way valve 7 under the action of the water pressure of the municipal tap water network;

[0039] When the steady flow water tank 5 is used to supply water to the user's household water pipe, the electric valve 40 is in an open state, and the one-way valve 7 is in a closed state due to the water pressure in the municipal tap water network. The water in the municipal tap water network passes through the secondary water pipe 2 and the tertiary water pipe 3 in turn and enters the steady flow water tank 5. When the water consumption of the surrounding users is small, the pressure in the municipal tap water network is relatively large. Under the pressure in the municipal tap water network, the water flows directly through the high-efficiency energy-saving submersible pump 9 in the steady flow water tank 5 into the output water pipe 37, and the pressure in the municipal tap water network is directly used to supply water to high-rise users, thereby saving energy. When the water consumption of the surrounding users is large, the pressure in the municipal tap water network is relatively small. When the water pressure is not enough to support the water level in the output water pipe 37 to the height of the user's floor, the water pressure sensor 10 detects When the water pressure drops to a preset value, the high-efficiency energy-saving submersible pump 9 will be started to increase the water pressure in the output water pipe 37 to supply water to high-rise residents. In addition, when the water pressure in the municipal tap water network is further reduced, resulting in the amount of water entering the steady flow water tank 5 from the tertiary water pipe 3 being less than the amount of water discharged to the output water pipe 37 through the high-efficiency energy-saving submersible pump 9, the water pressure sensor 10 will detect the negative pressure generated in the steady flow water tank 5, and the electric valve 40 will be closed at this time. Under the action of the one-way valve 7, the water in the water storage tank 8 will flow into the tertiary water pipe 3 through the one-way valve 7 and the secondary water pipe 2, and the water in the water storage tank 8 will be used as a supplement to the water source in the tertiary water pipe 3 to meet the water demand of high-rise users. During the use of the steady flow water tank 5, the attachments on the inner wall of the steady flow water tank 5 can be cleaned by the first cleaning rack 11 and the second cleaning rack 12.

[0040] Further, by Figure 2 - Figure 6 It is given that, in order to facilitate the cleaning of attachments in the steady-flow water tank 5, the steady-flow water tank 5 includes an upper tank body 13 and a lower tank body 14, the upper tank body 13 and the lower tank body 14 are sealed and connected by a flange, the high-efficiency and energy-saving submersible pump 9 is fixedly connected to the interior of the lower tank body 14, a sealing plate 15 is provided on the top of the lower tank body 14, a plurality of fixing plates 16 are fixedly connected to the upper side of the sealing plate 15, each fixing plate 16 is provided with a thread on the outer side, each fixing plate 16 is threadedly connected to the first cleaning frame 11 through a thread on the outer side, a first cleaning brush 17 is provided on the outer side of the first cleaning frame 11, and the first cleaning brush 17 moves up and down with the first cleaning frame 11 to form a structure for cleaning the interior of the upper tank body 13;

[0041] It should be noted that the sealing plate 15 can seal the top of the lower tank body 14. When the steady flow water tank 5 is in use, water is transported only through the upper tank body 13. The area between the lower tank body 14 and the sealing plate 15 is in a closed state, and water will not enter the lower tank body 14.

[0042] Further, by Figure 2 - Figure 6 It is given that in order to increase the cleaning area of ​​the lower tank body 14, a sliding groove 18 is provided on the outer periphery of the sealing plate 15, and a sliding ring 19 is slidably connected inside the sliding groove 18, and a gear ring 20 is fixedly connected to the upper side of the sliding ring 19, and a motor 21 is fixedly connected to the inside of the lower tank body 14. The motor 21 is a prior art and will not be described in detail here. The output end of the motor 21 passes through the sealing plate 15 and is fixedly connected to a gear 22, and the gear 22 is meshed with the inner side of the gear ring 20. A transmission rod 23 is fixedly connected to the upper side of the gear ring 20, and a transmission ring 24 is fixedly connected to the upper side of the transmission rod 23. The transmission ring 24 is slidably connected to the top of the upper tank body 13, and a sliding hole is provided at the position corresponding to each transmission rod 23 on the first cleaning frame 11, and each sliding hole is slidably connected to the corresponding transmission rod 23;

[0043] When in use, after starting the motor 21, the motor 21 drives the gear 22 to rotate, and then drives the gear ring 20 to rotate. When the gear ring 20 rotates, the first cleaning frame 11 is driven to rotate through each transmission rod 23. Since the first cleaning frame 11 is connected to each fixed plate 16 by a threaded connection, when the first cleaning frame 11 rotates, the first cleaning frame 11 will be lifted and lowered relative to the transmission rod 23 under the action of the sliding hole, and then the side wall of the upper tank body 13 and the side wall of each transmission rod 23 can be cleaned through the first cleaning frame 11.

[0044] Further, by Figure 2 - Figure 8 It is given that, in order to be able to clean the interior of the upper tank body 13 more thoroughly, an annular slide rail 25 is fixedly connected to the upper side of the first cleaning frame 11, and a plurality of first sliders 26 are slidably connected to the upper side of the annular slide rail 25, and fourth cleaning brushes 27 are fixedly connected to both sides of each first slider 26, and the lower side of each fourth cleaning brush 27 is in contact with the upper side of the first cleaning frame 11, and a side of each first slider 26 close to the second cleaning frame 12 is fixedly connected to the second cleaning frame 12, and a second cleaning brush 28 is provided on the outer side of the second cleaning frame 12;

[0045] Further, by Figure 5 - Figure 8 It is shown that a plurality of vertical rods 29 are fixedly connected to the upper side of the sealing plate 15, and a second slider 30 is slidably mounted on the outer side of each vertical rod 29, and each second slider 30 is fixedly connected to the second cleaning frame 12;

[0046] Further, by Figure 5 - Figure 8It is given that a third cleaning frame 31 is fixedly connected to the inner side of the second cleaning frame 12, and a third cleaning brush 32 is fixedly connected to the middle of the third cleaning frame 31. The middle part of the third cleaning brush 32 is elastic and can fit toward the direction of the high-efficiency energy-saving submersible pump 9 without being subjected to force;

[0047] When in use, since each vertical rod 29 is fixedly connected to the sealing plate 15, under the action of the second slider 30, each second cleaning frame 12 can only move up and down along the vertical rod 29, and then in the process of the first cleaning frame 11 rotating and lifting, the first slider 26 will be driven by the annular slide rail 25 to lift and lower, thereby driving the second cleaning frame 12 to lift and lower relative to each fixed plate 16, so that each second cleaning brush 28 can clean the inner side of the fixed plate 16, and at the same time, the second cleaning frame 12 will drive the third cleaning frame 31 to lift and lower, and then the surface of the high-efficiency and energy-saving submersible pump 9 is cleaned by the third cleaning brush 32, and since each first slider 26 is always rotating relative to the second cleaning frame 12, the fourth cleaning brush 27 can clean the upper surface of the second cleaning frame 12;

[0048] It should be noted that a cleaning pipe is connected to the side of the upper tank body 13. When the steady flow water tank 5 needs to be cleaned, the cleaned water in the steady flow water tank 5 can be emptied through the cleaning pipe.

[0049] Further, by Figure 1 - Figure 4 It is given that, in order to achieve a better water delivery effect, the water inlet end of the upper tank body 13 is connected to a soft water pipe 33, the output end of the high-efficiency energy-saving submersible pump 9 is connected to a water pump pipe 34, and the water pump pipe 34 is connected to the input end of the output water pipe 37;

[0050] When in use, the soft water pipe 33 can absorb vibration, compensate for the displacement of the steady flow water tank 5 and reduce water delivery noise.

[0051] Further, by Figure 1 It is shown that a float valve 35 is provided at the input end of the water storage tank 8; the float valve 35 is a prior art and is used to automatically add water to the water storage tank 8;

[0052] It should be noted that valves 36 are provided between the municipal tap water network and the secondary water pipe 2, between the secondary water pipe 2 and the tertiary water pipe 3, at the input and output ends of the steady flow water tank 5, and at the input and output ends of the high-efficiency energy-saving pump group 4. The valve 36 can be a gate valve, a butterfly valve, a stop valve, or a ball valve, and no excessive restrictions are made here. In addition, a soft water pipe 33 is also provided at the output end of the steady flow water tank 5 to reduce the vibration and noise of water transportation.

[0053] When the present invention is used, the high-efficiency energy-saving pump group 4 is used as a pressurizing device for the original user's household water pipe, and the water in the water storage tank 8 is lifted to a suitable height to meet the water needs of high-rise users. On the basis of keeping the original water supply line of the high-efficiency energy-saving pump group 4 unchanged, the connecting pipe 6, the tertiary water pipe 3, and the steady flow water tank 5 are connected at the end of the secondary water pipe 2, that is, the high-efficiency energy-saving pump group 4 is connected in parallel through the connecting pipe 6, the tertiary water pipe 3 and the steady flow water tank 5, and then the output water pipe 37 is supplied with water through the steady flow water tank 5, and the high-efficiency energy-saving pump group 4 is used as a standby water supply device;

[0054] When the steady flow water tank 5 is used to supply water to the user's household water pipe, the water in the municipal tap water network passes through the secondary water pipe 2 and the tertiary water pipe 3 in turn and enters the steady flow water tank 5. When the water consumption of the surrounding users is small, the pressure in the municipal tap water network is relatively large. Under the action of the pressure in the municipal tap water network, the water flows directly into the output water pipe 37 through the high-efficiency and energy-saving submersible pump 9 in the steady flow water tank 5, and the pressure in the municipal tap water network is directly used to supply water to high-rise users, thereby saving energy. When the water consumption of the surrounding users is large, the pressure in the municipal tap water network is relatively small. When the water pressure is not enough to support the water level in the output water pipe 37 to the height of the user's floor, the water pressure sensor 10 detects that the water pressure has dropped to a preset value, and then starts the high-efficiency and energy-saving submersible pump 9 to increase the water in the output water pipe 37. pressure to supply water to high-rise residents. In addition, when the water pressure in the municipal water network is further reduced, resulting in the water inflow from the tertiary water pipe 3 to the steady flow water tank 5 being less than the water outflow from the high-efficiency energy-saving submersible pump 9 to the output water pipe 37, the water pressure sensor 10 will detect the negative pressure in the steady flow water tank 5. At this time, the electric valve 40 will be closed, and the water in the water storage tank 8 will be used as a supplement to the water source in the tertiary water pipe 3 to meet the water demand of high-rise users. When it is detected that the water pressure in the municipal water network is greater than the preset value, the solenoid valve 40 can be started to open it, and water can be directly supplied through the municipal water network. At this time, the water in the water storage tank 8 will be fully replenished. During the use of the steady flow water tank 5, the attachments on the inner wall of the steady flow water tank 5 can be cleaned by the first cleaning rack 11 and the second cleaning rack 12;

[0055] It should be noted that, in general, when the water storage tank 8 is used as a backup water source, the water in the water storage tank 8 will be stored for a long time, thereby causing the water quality to deteriorate after the water is stored for a long time. After the steady flow water tank 5 is provided, the water in the water storage tank 8 will be used for water supply when the water pressure in the municipal tap water network decreases every day. Therefore, the water in the water storage tank 8 can be renewed and replaced every day, thereby ensuring the freshness and stability of the water quality in the water storage tank 8.

[0056] Furthermore, the system also includes a controller that can control the electric valve 40, thereby timely controlling the discharge and use time of the water source in the water storage tank 8, and renewing the water in the water storage tank 8;

[0057] When it is necessary to clean the inside of the steady flow water tank 5, the motor 21 can be started, and the motor 21 drives the gear 22 to rotate, thereby driving the gear ring 20 to rotate. When the gear ring 20 rotates, each transmission rod 23 drives the first cleaning frame 11 to rotate. Since the first cleaning frame 11 and each fixed plate 16 are connected by threads, when the first cleaning frame 11 rotates, the first cleaning frame 11 will be lifted and lowered relative to the transmission rod 23 under the action of the sliding hole, so that the side wall of the upper tank body 13 and the side wall of each transmission rod 23 can be cleaned through the first cleaning frame 11. In addition, since each vertical rod 29 is fixedly connected to the sealing plate 15, each vertical rod 29 is fixedly connected to the sealing plate 15 under the action of the second slider 30. The second cleaning frame 12 can only move up and down along the vertical rod 29, and then when the first cleaning frame 11 is lifted and lowered while rotating, the first slider 26 will be lifted and lowered driven by the annular slide rail 25, thereby driving the second cleaning frame 12 to lift and lower relative to each fixed plate 16, so that each second cleaning brush 28 can clean the inner side of the fixed plate 16. At the same time, the second cleaning frame 12 will drive the third cleaning frame 31 to lift and lower, and then the surface of the high-efficiency and energy-saving submersible pump 9 will be cleaned by the third cleaning brush 32. Since each first slider 26 is always rotating relative to the second cleaning frame 12, the fourth cleaning brush 27 can clean the upper surface of the second cleaning frame 12.

[0058] The present invention has a novel structure, an ingenious conception, and is simple and convenient to operate. Through this design, the purpose of utilizing the water pressure in the municipal water pipe for high-rise water supply is effectively achieved. Through the secondary water pipe 2, the tertiary water pipe 3 and the steady flow water tank 5, the energy loss of the system is reduced. The water tank 8 can be used as a water source to supplement the water, thereby improving the water use stability of high-rise users. By using the water in the water tank 8 in a timely manner, the storage time of the water in the water tank 8 can be reduced, the stability of the water quality is improved, and the overall energy consumption of the system is reduced. The impurities in the steady flow water tank 5 can be easily cleaned, and the cleaning area inside the steady flow water tank 5 is increased. The inside of the steady flow water tank 5 can be cleaned more thoroughly, achieving a better water delivery effect. The displacement of the steady flow water tank 5 can be compensated when the staff is installing it, and the absorption vibration and water delivery noise can be reduced.

[0059] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
