Description

Technical Field

[0001] This application relates to the field of water supply equipment technology, and in particular to a dynamic pipeline superimposed pressure water supply system. Background Technology

[0002] Pressure boosting is a secondary water supply method that utilizes the residual pressure of the outdoor water supply network to directly pump water and then pressurize it. It mainly consists of the municipal water supply network, vacuum suppressors and pressure stabilizing tanks, water pump units, automatic control cabinets, water supply tanks, and user water supply networks.

[0003] The main feature of the superimposed pressure water supply system is that it can make full use of the municipal water supply network pressure. During the off-peak water consumption period, the municipal water supply network is under high pressure, and a portion of the water flows into the water supply tank for storage. During the peak water supply period, the municipal water supply network is under low pressure, and the pressure is insufficient to supply water to the user end. At this time, the municipal water supply network and the water supply tank supply water to the user end simultaneously. The water flows into the user side after being pressurized by the pressure stabilizing tank 2.

[0004] However, in actual operation, it was found that the water in the water supply tank needs to be disinfected, otherwise the water quality will decline. If the water in the water supply tank is supplied to the user, it will harm the user's physical and mental health. Summary of the Invention

[0005] The purpose of this application is to provide a booster water supply system capable of disinfecting the water flow in a water supply tank.

[0006] The dynamic pipeline superimposed pressure water supply system provided in this application adopts the following technical solution:

[0007] A dynamic pipeline superimposed pressure water supply system includes a water supply tank, a pressure stabilizing tank, an inlet pipe for connecting to the municipal pipeline network, and a water delivery pipe for supplying water to users. It also includes a partition plate, which is placed inside the water supply tank and isolates the water supply tank, forming a first inner cavity and a second inner cavity arranged sequentially in the vertical direction.

[0008] The second inner cavity, the pressure stabilizing tank, and the water supply pipeline are connected in sequence. The water inlet pipeline is connected to the first inner cavity and the pressure stabilizing tank respectively. An adjusting component for detecting the liquid level is provided in the first inner cavity. A receiving cavity is opened in the partition plate and the receiving cavity stores disinfectant. The adjusting component is partially inserted into the receiving cavity. When the liquid level in the first inner cavity rises, the adjusting component squeezes the disinfectant into the second inner cavity.

[0009] By adopting the above technical solution, when the municipal water supply pipeline is under high pressure, a portion of the water flows into the water supply tank for storage. When the water flows into the water supply tank, it enters the first inner cavity. When the water in the first inner cavity accumulates to a certain height, the regulating component also rises with the change in liquid level, causing the disinfectant in the receiving cavity to be squeezed into the water in the second inner cavity, which has been stored for a long time. This disinfection ensures the cleanliness of the water when it is supplied to the user.

[0010] Optionally, the adjusting component includes a pusher plate, a float plate, and a retractable pusher rod. The two ends of the pusher rod are respectively connected to the pusher plate and the float plate. The receiving cavity includes a storage cavity for storing disinfectant and an arc-shaped discharge channel. The receiving cavity is connected to the discharge channel. The pusher plate is placed in the storage cavity and can move vertically.

[0011] By adopting the above technical solution, when water flows into the first inner cavity, the regulating component rises with the change of liquid level. At this time, the pusher plate rises and moves vertically in the receiving cavity, pushing the disinfectant in the receiving cavity to move. Some disinfectant is squeezed from the receiving cavity into the discharge channel and finally falls into the second inner cavity to disinfect the water in the second inner cavity. The discharge channel is arc-shaped to prevent water from entering the receiving cavity.

[0012] Optionally, the partition plate also has an injection chamber for injecting material into the receiving cavity. The injection chamber is higher than the receiving cavity. An injection channel is connected between the injection chamber and the receiving cavity. A one-way valve is connected to both the injection channel and the discharge channel.

[0013] By adopting the above technical solution, after the pusher plate squeezes part of the disinfectant into the second inner cavity, the injection cavity can replenish the disinfectant into the receiving cavity. The one-way valve is set at the injection channel and the discharge channel to prevent the disinfectant in the receiving cavity from flowing back into the injection cavity, and also to prevent the water in the second inner cavity from flowing back into the receiving cavity, thus ensuring the stable operation of the equipment.

[0014] Optionally, the push rod includes a first push rod and a second push rod. The first push rod is connected to the push plate. The other end of the first push rod is provided with an insertion groove for the second push rod to be inserted. One end of the second push rod is connected to the float plate, and the other end of the second push rod is inserted into the insertion groove.

[0015] The second push rod has a mating groove and a mating component that drives the first push rod to move. The mating component includes a ramp block and a limiting rod. The limiting rod is inserted into the mating groove and has an elastic element sleeved on its outer end. The two ends of the elastic element act on the ramp block and the bottom wall of the mating groove, respectively. The first push rod has a serrated groove that mates with the ramp block.

[0016] By adopting the above technical solution, when the liquid level in the first inner cavity rises, the second push rod rises along with the liquid level due to buoyancy. At this time, the ramp block abuts against the side wall of the sawtooth groove, and the ramp block drives the first push rod to rise. At this time, the push plate connected to the first push rod squeezes out the disinfectant. When the liquid level in the first inner cavity drops, the second push rod extends into the first push rod. In this way, the length of the push rod can be adjusted to accommodate the rise and fall of the liquid level with a small space occupation, and the space arrangement is more reasonable.

[0017] Optionally, the float is connected to a counterweight that drives the second push rod to penetrate deeper into the first push rod.

[0018] By adopting the above technical solution, the counterweight allows the adjusting component to respond more quickly to changes in liquid level, which helps to ensure adjustment accuracy.

[0019] Optionally, a sealing plate is slidably connected to the partition plate, and water passage holes are provided on both the partition plate and the sealing plate. The top of the counterweight is cone-shaped, and two opposing movable plates are connected to the first inner cavity. The movable plates are connected to the sealing plate, and the counterweight can push the movable plates to move as the liquid level rises.

[0020] By adopting the above technical solution, when the liquid level in the second inner cavity rises to a significant height, there is very little space left in the second inner cavity. At this time, the top of the counterweight is inserted into the movable plate, and the arc-shaped surface of the counterweight pushes the movable plate to move. The movable plate then drives the sealing plate to move, causing the originally misaligned water passages to overlap to a certain extent. At this time, the first inner cavity and the second inner cavity are connected, and some water in the first inner cavity enters the second inner cavity through the water passages to replenish the second inner cavity, which mainly supplies water to the user. At this time, the liquid level in the second inner cavity also begins to drop, and the counterweight drops along with the liquid level, causing the counterweight to disengage from the movable plate. The water passages opened on the sealing plate and the partition plate are then re-altered, and the channel between the first inner cavity and the second inner cavity is blocked. This arrangement ensures the stable operation of the water supply.

[0021] Optionally, a groove is provided on the inner wall of the water supply tank in the vertical direction, and guide plates extend from both sides of the partition plate. The guide plates are inserted into the groove and slide along the opening direction of the groove.

[0022] By adopting the above technical solution, the guide plate can constrain the movement of the partition plate, ensure the stable vertical movement of the partition plate, and improve the stability of the partition plate's movement.

[0023] Optionally, a wedge block is connected to the bottom side of the sealing plate, and a limiting groove matching the wedge block is provided on the partition plate. The wedge block is slidably connected in the limiting groove. An inclined push plate is connected to the side wall of the second inner cavity. The inclined push plate can support the partition plate and push the wedge block to move.

[0024] By adopting the above technical solution, when water in the second inner cavity is continuously supplied to the user side, the water level in the second inner cavity continuously drops, causing the position of the partition plate in the water supply tank to also continuously decrease. This causes the partition plate to move closer to the inclined push plate, and the inclined surface of the inclined push plate contacts the inclined wedge block. The two inclined surfaces interact, causing the sealing plate to be pushed. The sealing plate coincides with the water passage hole on the movable plate, so that the first inner cavity and the second inner cavity are connected and water is supplied to the second inner cavity, which helps to ensure that the water supply in the second inner cavity remains stable.

[0025] Optionally, it also includes a control cabinet and a valve assembly connected to the water inlet pipe and the water delivery pipe. The control cabinet can control the opening and closing of the valve assembly. A control element is embedded in the bottom wall of the insertion slot. The control element is electrically connected to the control cabinet. When the second push rod contacts the control element, the water inlet pipe supplies water to the first inner cavity.

[0026] By adopting the above technical solution, the control cabinet macroscopically regulates the flow direction of water by controlling the opening and closing of the control valve group. When the second push rod contacts the control element, the liquid level in the first inner cavity is at a low level, indicating that the water in the water supply tank is insufficient. The control element sends a signal to the control cabinet, and the control cabinet further opens the valve group on the water inlet pipe connected to the first inner cavity, so that the water inlet pipe supplies a certain amount of water to the water supply tank, ensuring that the water supply tank can function stably when the water supply demand is high.

[0027] Optionally, the pressure stabilizing tank is connected to a negative pressure vacuum suppressor and a pressure sensor, both of which are electrically connected to the control cabinet.

[0028] By adopting the above technical solutions, the pressure sensor and the pressure-covering vacuum suppressor can provide timely feedback on the real-time working status inside the pressure-stabilizing pipe, ensuring the stable operation of the water supply system.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] 1. This application is equipped with a water supply tank. When the municipal water supply pipeline is under high pressure, a portion of the water flows into the water supply tank for storage. When the water flows into the water supply tank, it enters the first inner cavity. When the water in the first inner cavity accumulates to a certain height, the regulating element also rises with the change of liquid level, so that the disinfectant in the receiving cavity is squeezed into the water in the second inner cavity, which has been stored for a long time, and then disinfected. When water is supplied to the user, the cleanliness of the water quality is ensured.

[0031] 2. The push rod in this application is telescopic. When the liquid level in the first inner cavity rises, the second push rod rises along with the liquid level due to buoyancy. At this time, the ramp block abuts against the side wall of the sawtooth groove, and the ramp block drives the first push rod to rise. At this time, the push plate connected to the first push rod squeezes out the disinfectant. When the liquid level in the first inner cavity drops, the second push rod extends into the first push rod. In this way, the length of the push rod is adjustable, so as to cope with the rise and fall of the liquid level with a small space occupation, and the space arrangement is more reasonable.

[0032] 3. This application achieves the connection or closure between the first and second cavities by moving the sealing plate. When the liquid level in the second inner cavity rises to a significant height, there is little remaining space in the second inner cavity. At this time, the top of the counterweight is inserted into the movable plate, and the arc-shaped surface of the counterweight pushes the movable plate to move. The movable plate then further drives the sealing plate to move, causing the originally misaligned water passages to overlap to a certain extent. At this time, the first and second inner cavities are connected, and some water in the first inner cavity enters the second inner cavity through the water passages to replenish the second inner cavity, which mainly supplies water to the user. At this time, the liquid level in the second inner cavity also begins to drop, and the counterweight drops along with the liquid level, causing the counterweight to disengage from the movable plate. The water passages opened on the sealing plate and the partition plate are re-altered, and the channel between the first and second inner cavities is blocked. This arrangement ensures the stable operation of the water supply. Attached Figure Description

Detailed Implementation

[0039] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.

[0040] A dynamic pipe network booster water supply system, referring to Figure 1 and Figure 2 It includes a water supply tank 1, a pressure stabilizing tank 2, an inlet pipe 3 for connecting to the municipal pipe network, and a water delivery pipe 4 for supplying water to users. The water supply tank 1 is equipped with a partition plate 5 to separate the water supply tank 1, forming a first inner cavity 11 and a second inner cavity 12 arranged in sequence along the vertical direction. The second inner cavity 12, the pressure stabilizing tank 2 and the water delivery pipe 4 are connected in sequence, and the inlet pipe 3 is connected to the first inner cavity 11 and the pressure stabilizing tank 2 respectively.

[0041] The water inlet pipeline 3 includes a first pipeline 31 and a second pipeline 32 that are interconnected. The first pipeline 31 is connected to the pressure stabilizing tank 2, and the second pipeline 32 is connected to the first inner cavity 11 inside the water supply tank 1. The water delivery pipeline 4 includes a main pipeline 41 and several branch pipelines 42 connected to the main pipeline 41. The main pipeline 41 is connected to the pressure stabilizing tank 2 and is used to supply water to the user side. The several branch pipelines 42 respectively deliver water to each user side.

[0042] Reference Figure 1The booster water supply system also includes a control cabinet 20 and a valve group 9 connected to the inlet pipe 3 and the delivery pipe 4. The control cabinet 20 can control the opening and closing of the valve group 9, which mainly includes solenoid valves connected to the first pipe 31 and the second pipe 32, and pump groups connected to several branch pipes 42. In addition, the pressure tank 2 and the second inner cavity 12 are also connected by a pipe, which is also connected to a solenoid valve. All these valves and pump groups are controlled by the control cabinet 20.

[0043] When the water inlet pipe 3 is under high pressure, the solenoid valve on the second pipe 32 is opened under the control of the control cabinet 20, and the water supply tank 1 stores water. When the water inlet pipe 3 is under normal pressure or low pressure, the solenoid valves on the second pipe are closed. The difference is that when the pressure is low, the solenoid valve on the pipe between the pressure stabilizing tank 2 and the second inner cavity 12 is opened to supply water to the user side.

[0044] Furthermore, the inlet pipe 3, the delivery pipe 4, and the pipes between the pressure tank 2 and the second inner cavity 12 are also connected to electromagnetic flow meters 60. These electromagnetic flow meters 60 are also electrically connected to the control cabinet 20 and transmit the real-time flow status in the pipes to the control cabinet 20. The control cabinet 20 then sends control signals to the corresponding valves based on the information transmitted by the electromagnetic flow meters 60.

[0045] In addition, a negative pressure vacuum suppressor 40 and a pressure sensor 50 are connected to the pressure stabilizing tank 2. Both the negative pressure vacuum suppressor 40 and the pressure sensor 50 are electrically connected to the control cabinet 20. The pressure sensor 50 is connected to the main pipeline to monitor the pressure of the water flow when the pressure stabilizing tank 2 supplies water to the user side, while the negative pressure vacuum suppressor 40 regulates the pressure inside the pressure stabilizing tank 2 to prevent backflow of water or failure to drain due to negative pressure.

[0046] Reference Figure 1 and Figure 2 The first inner cavity 11 is set higher than the second inner cavity 12. The first inner cavity 11 has a water inlet for connecting to the water inlet pipe 3, and the second inner cavity 12 has a water outlet for connecting to the pressure stabilizing tank 2. In addition, the inner wall of the water supply tank 1 has a vertical groove 13, and guide plates 54 extend from both sides of the partition plate 5. The guide plates 54 are inserted into the groove 13 and slide along the opening direction of the groove 13.

[0047] When the water inlet pipe 3 supplies water to the first inner cavity 11, or the second inner cavity 12 supplies water to the pressure stabilizing tank 2, the liquid level in the water supply tank 1 will change. The position of the partition plate 5 will move along with the change in the liquid level in the first inner cavity 11 and the second inner cavity 12. Constrained by the guide plate 54, the partition plate 5 moves stably in the vertical direction, ensuring the partition plate 5 isolates the first inner cavity 11 and the second inner cavity 12.

[0048] Reference Figure 2 and Figure 3 The first inner cavity 11 is provided with an adjusting member 6 for detecting the liquid level. The partition plate 5 has a receiving cavity 51 which contains disinfectant. The adjusting member 6 is partially inserted into the receiving cavity 51. When the liquid level in the first inner cavity 11 rises, the adjusting member 6 squeezes the disinfectant into the second inner cavity 12.

[0049] Specifically, the adjusting component 6 includes a pusher plate 62, a float plate 63, and a telescopic pusher rod 61. The two ends of the pusher rod 61 are connected to the pusher plate 62 and the float plate 63, respectively. The receiving cavity 51 includes a storage cavity 511 for storing disinfectant and an arc-shaped discharge channel 512. The receiving cavity 51 is connected to the discharge channel 512. The pusher plate 62 is placed in the storage cavity 511 and can move vertically.

[0050] In this embodiment, the relative movement process between the adjusting member 6 and the partition plate 5 is as follows: the float plate 63 is generally hemispherical and located above the liquid surface. When the liquid level in the first inner cavity 11 rises, the push rod 61 moves upward, driving the push plate 62 placed in the storage cavity 511 to move. During the movement, the push plate 62 squeezes the disinfectant placed in the storage cavity 511 into the discharge channel 512 and finally into the second inner cavity 12 to deal with the situation where the water in the second inner cavity 12 is stored for a long time.

[0051] Reference Figure 2 and Figure 3 The partition plate 5 also has an injection cavity 52 for injecting material into the storage cavity 511. The injection cavity 52 is annular in shape to supply material to the storage cavity 511. The injection cavity 52 is higher than the receiving cavity 51. In addition, an injection channel 53 is connected between the injection cavity 52 and the receiving cavity 51. Multiple injection channels 53 can be provided. In this embodiment, there are two injection channels 53 and they are arranged opposite to the storage cavity 511.

[0052] When the liquid level in the first inner cavity 11 drops, the push rod 61 retracts to the initial position, and the push plate 62 abuts against the bottom wall of the storage cavity 511. Since the injection cavity 52 is higher than the receiving cavity 51, the disinfectant in the injection cavity 52 will flow into the storage cavity 511 for replenishment. The disinfectant is liquid and can be any one of hypochlorous acid, chlorine dioxide, or sodium hypochlorite. In this embodiment, sodium hypochlorite is used as the disinfectant.

[0053] Reference Figure 3 In order to prevent some disinfectant from entering the injection chamber 52 or water from the second inner chamber 12 from entering the storage chamber 511 during the process of the pusher plate 62 squeezing the disinfectant in the storage chamber 511 into the second inner chamber 12, one-way valves 70 are connected in both the injection channel 53 and the discharge channel.

[0054] Reference Figure 2 and Figure 4 The push rod 61 is telescopic and includes a first push rod 611 and a second push rod 612. The first push rod 611 is connected to the push plate 62. The other end of the first push rod 611 is provided with an insertion groove 6111 for the second push rod 612 to be inserted. One end of the second push rod 612 is connected to the float plate 63, and the other end of the second push rod 612 is inserted into the insertion groove 6111.

[0055] The second push rod 612 has a mating groove 6121 and a mating component 64 that drives the first push rod 611 to move. The mating component 64 includes a ramp block 641 and a limiting rod 642. The limiting rod 642 is inserted into the mating groove 6121 and an elastic element 643 is sleeved on its outer end. The two ends of the elastic element 643 act on the ramp block 641 and the bottom wall of the mating groove 6121, respectively. The first push rod 611 has a serrated groove 6112 that mates with the ramp block 641.

[0056] A control element 30 is embedded in the bottom wall of the insertion slot 6111. The control element 30 is electrically connected to the control cabinet 20. When the second push rod 612 contacts the control element 30, if the water inlet pipe 3 returns from low pressure to normal pressure, the control box still controls the solenoid valve on the second pipe 32 to open, so as to supply water to the first inner cavity 11 at the expense of a certain pressure. When the second push rod 612 rises and no longer contacts the control element 30, the solenoid valve closes.

[0057] Reference Figure 2 and Figure 5 The float plate 63 is connected to a counterweight block 65 that drives the second push rod 612 to penetrate deeper into the first push rod 611, so as to respond more quickly to changes in liquid level. The partition plate 5 is slidably connected to a sealing plate 7. Both the partition plate 5 and the sealing plate 7 have water passage holes 8. The top of the counterweight block 65 is cone-shaped. The first inner cavity 11 is provided with two opposing movable plates 80. The two movable plates 80 are long plates and can move laterally along their own length.

[0058] It should be noted that the movable plate 80 is moved laterally by the counterweight 65 as the liquid level rises.

[0059] Specifically, the top of the movable plate 80 abuts against the top wall of the first inner cavity 11, the sides of the movable plates 80 that are far apart from each other are in clearance fit with the side wall of the first inner cavity 11, and the sides of the movable plates 80 that are close to each other are also in clearance fit and have a slope to allow the counterweight 65 with a conical top to be inserted. The movable plate 80 and the sealing plate 7 are connected by a vertical rod, wherein one end of the vertical rod is detachably connected to the movable plate 80 by a bolt, and the other end of the vertical rod is detachably connected to the sealing plate 7 by a bolt.

[0060] Furthermore, in this embodiment, the vertical rod is telescopic, mainly comprising two connecting rods and a spring located between the two connecting rods. The two ends of the spring respectively abut against the ends of the two connecting rods that are close to each other. The extension and contraction of the spring realizes the extension and contraction of the vertical rod. It should be noted that telescopic vertical rods are a relatively mature technology, and will not be described in detail here.

[0061] When the liquid level in the first inner cavity 11 rises, the float 63 drives the counterweight 65 to move vertically upward as the liquid level rises. As the counterweight 65 gradually moves upward, it gradually cooperates with the slope, pushing the two movable plates 80 to move laterally and move away from each other. The movable plates 80 further drive the sealing plate to move, so that the originally staggered water passage holes 8 on the movable plates 80 and the sealing plate 7 overlap. The first inner cavity 11 is connected to the second inner cavity 12 and water is supplied to the second inner cavity 12.

[0062] In this embodiment, a spring is provided in the gap between the movable plate 80 and the side wall of the first inner cavity 11. The two ends of the spring are fixedly connected to the movable plate 80 and the side wall of the first inner cavity 11, respectively. When the water level of the second inner cavity 12 drops and the counterweight 65 disengages from the movable plate 80, the originally contracted spring rebounds, causing the movable plate 80 to reset. It should be noted that the spring is not specifically drawn.

[0063] Furthermore, a wedge block 71 is connected to the bottom side of the sealing plate 7, and a limiting groove 55 matching the wedge block 71 is provided on the partition plate 5. The wedge block 71 is slidably connected in the limiting groove 55. An inclined push plate 10 is connected to the side wall of the second inner cavity 12. The inclined push plate 10 can support the partition plate 5 and push the wedge block 71 to move.

[0064] Specifically, when the second inner cavity 12 continuously supplies water to the user side, the water level in the second inner cavity 12 drops. The partition plate 5 and the sealing plate 7 move vertically downward in sync with the drop in the water level in the second inner cavity 12. During the movement, the wedge block 71 gradually approaches the inclined push plate 10. When the wedge block 71 contacts the inclined push plate 10, if the wedge block 71 is still moving downward, the inclined surface on the inclined push plate 10 will cooperate with the slope of the wedge block 71, pushing the sealing plate 7 to move laterally towards the center of the partition plate 5, so that the movable plate 80 and the originally intersecting water passage holes 8 on the sealing plate 7 overlap, and the first inner cavity 11 connects with the second inner cavity 12 and supplies water to the second inner cavity 12.

[0065] The implementation principle of this application embodiment is as follows:

[0066] When the municipal water supply pipe 3 is under high pressure, a portion of the water flows into the water supply tank 1 for storage. When the water flows into the water supply tank 1, it enters the first inner cavity 11. When the water in the first inner cavity 11 accumulates to a certain height, the regulating component 6 also rises with the change in liquid level, causing the disinfectant in the receiving cavity 51 to be squeezed into the water in the second inner cavity 12, which has been stored for a long time, so that the water is disinfected. When water is supplied to the user, the cleanliness of the water quality is ensured.

[0067] When the municipal water supply pipe 3 is under low pressure, the second inner cavity 12 begins to supply water to the user side, causing the height of the partition plate 5 to decrease. If the partition plate 5 contacts the inclined push plate 10, the sealing plate 7 is pushed, and the first inner cavity 11 and the second inner cavity 12 are connected and water is supplied to the first inner cavity 11. At this time, the liquid level in the second inner cavity 12 also begins to decrease significantly, and the second push rod 612 begins to move relative to the first push rod 611. When the second push rod 612 contacts the control element 30, the control cabinet 20 begins to control the valve group 9. When the low pressure returns to normal pressure, the solenoid valve on the second pipe 32 opens to replenish water to the water supply tank 1, ensuring a stable water supply to the user under low pressure.

[0068] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be included within the scope of protection of this application.
