Description

Technical Field

[0001] This utility model belongs to the field of water supply buffer technology, specifically relating to a negative pressure-free water supply buffer structure. Background Technology

[0002] The negative pressure-free water supply equipment we usually refer to is generally a negative pressure-free variable frequency water supply equipment, also called a variable frequency negative pressure-free water supply equipment. It is a booster device that is directly connected to the water supply network. Negative pressure-free water supply is a highly efficient and energy-saving water supply method. It utilizes the original pressure of the municipal water supply network to achieve a closed-loop continuous booster water supply, avoiding secondary pollution of water quality. The inlet pipe of the negative pressure-free water supply equipment is directly connected to the tap water network. Water is forced into the inlet pipe of the equipment under the residual pressure of the tap water network. The booster pump of the equipment continues to pressurize on the basis of the residual pressure of the inlet water, and then supplies water to the outlet network after raising the water supply pressure to the pressure required by the user. High pressure water flow directly entering the water supply tank can easily cause violent impact force and damage to the inside of the tank. Therefore, a buffer structure is required. A search revealed Chinese patent CN215630403U, which discloses a negative pressure-free water supply device for residential communities. This device includes a movable base with a negative pressure suppressor on its upper part. A tank is fixed above the top of the movable base, and a drive motor is fixed to the top of the tank. This invention can extend the service life of the tank to a certain extent. Furthermore, it allows for cleaning of the inner wall of the tank when needed, offering good performance, flexibility, and convenience. The entire device has a simple structure and low manufacturing cost. However, it still has the following drawbacks: traditional buffer structures use a fixed end and a buffer spring on the other end, with a vertical baffle fixed on the other side. These two components work together to buffer the incoming water flow. However, when the inclined plate is subjected to impact, because one end of the inclined plate is fixed, the large impact force causes the inclined plate to rotate excessively, failing to block the subsequent water flow. Furthermore, the fixed vertical baffle is easily damaged under long-term rigid contact. Therefore, a negative pressure-free water supply buffer structure is proposed. Utility Model Content

[0003] The purpose of this invention is to provide a negative pressure-free water supply buffer structure to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a negative pressure-free water supply buffer structure, including an installation plate fixed to the top of the inner cavity of a negative pressure-free water supply tank, a corresponding hole in the middle of the installation plate, a support frame fixedly connected to one side of the bottom of the installation plate, a plurality of first stabilizing rods fixedly connected to the middle of the support frame, a buffer plate sleeved on the top of the first stabilizing rod, a pressure plate fixedly connected to one side of the bottom of the buffer plate, and a first spring sleeved on the bottom end of the first stabilizing rod; Two limiting strips are fixedly connected to the bottom of the mounting plate on the side away from the support frame. Multiple second stabilizing rods are fixedly connected between the two limiting strips. A second spring and a baffle are sleeved in the middle of the second stabilizing rod.

[0005] Preferably, the mounting plate has mounting holes around its perimeter, and the corresponding holes correspond to the water inlet pipe of the negative pressure-free water supply tank.

[0006] Preferably, the cross-sectional shape of the support frame is set to "U" shape, the first stabilizing rod passes through the middle of the pressure plate, and the pressure plate is set on the top of the first spring.

[0007] Preferably, one end of the buffer plate extends directly below the corresponding hole, the end of the buffer plate near the baffle is lower than the other side, and the size of the buffer plate is larger than the diameter of the corresponding hole.

[0008] Preferably, the bottom length of the baffle is greater than the top length of the baffle, and the bottom of the baffle is lower than the bottom of the support frame.

[0009] Preferably, the second spring is disposed on the side of the baffle away from the buffer plate.

[0010] Preferably, the surface array of the baffle has multiple dispersive holes, and both the baffle and the buffer plate are hard plastic plates.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, when the buffer plate drives the pressure plate to squeeze the first spring, the buffer plate moves up and down as a whole. This can improve the buffering effect by not affecting the subsequent water flow during the process of blocking and buffering the water flow. Furthermore, by using the baffle to squeeze and buffer the second spring in an impact manner, the baffle can be prevented from being damaged by direct hard contact with the water flow, thus improving the buffering effect.

[0012] 2. This utility model also uses a dispersion hole to divide the water flow into multiple fine streams, reducing the water flow rate and allowing the water to flow smoothly into the water supply tank, thus achieving a buffering effect. Furthermore, the support frame and the first stabilizing rod improve the stability of the buffer plate's lifting and moving motion, further enhancing the buffering effect.

[0013] In summary, through the interaction of the above-mentioned multiple functions, the buffering effect on subsequent water flow can be maintained during the process of blocking and buffering the impact of water flow. At the same time, the vertical baffle is prevented from being damaged by direct hard contact with the water flow, which can reduce the water flow rate and improve the buffering effect.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-3 This utility model provides a negative pressure water supply buffer structure, including an installation plate 1 fixed to the top of the inner cavity of the negative pressure water supply tank, a corresponding hole 2 opened in the middle of the installation plate 1, a support frame 3 fixedly connected to the bottom side of the installation plate 1, a plurality of first stabilizing rods 4 fixedly connected to the middle of the support frame 3, a buffer plate 5 sleeved on the top of the first stabilizing rod 4, a pressure plate 6 fixedly connected to the bottom side of the buffer plate 5, and a first spring 7 sleeved on the bottom end of the first stabilizing rod 4. The cross-sectional shape of the support frame 3 is set as "U" shape. The first stabilizing rod 4 passes through the middle of the pressure plate 6. The pressure plate 6 is set on the top of the first spring 7. One end of the buffer plate 5 extends directly below the corresponding hole 2. The end of the buffer plate 5 near the baffle 11 is lower than the other side. The size of the buffer plate 5 is larger than the diameter of the corresponding hole 2. In this embodiment, the water flow directly impacts the buffer plate 5, which can convert the vertically impacting water flow into an oblique flow, avoiding the water flow from directly impacting the tank wall. At the same time, it guides the water flow towards the baffle 11, forming an orderly flow pattern and expanding the water flow range. When the buffer plate 5 is impacted, it will cause the pressure plate 6 to squeeze the first spring 7. The spring deformation absorbs the impact force, reduces the impact pressure of the water flow, and improves the stability of the buffer plate 5's lifting and moving through the first stabilizing rod 4.

[0018] Two limiting strips 8 are fixedly connected to the bottom of the mounting plate 1 on the side away from the support frame 3. Multiple second stabilizing rods 9 are fixedly connected between the two limiting strips 8. A second spring 10 and a baffle 11 are sleeved in the middle of the second stabilizing rod 9. The bottom length of the baffle 11 is greater than the top length of the baffle 11. The bottom of the baffle 11 is lower than the bottom of the support frame 3. The second spring 10 is set on the side of the baffle 11 away from the buffer plate 5. Multiple dispersion holes 12 are arrayed on the surface of the baffle 11. Both the baffle 11 and the buffer plate 5 are hard plastic plates. In this embodiment, the water flow guided by the buffer plate 5 impacts the baffle 11, which can buffer the impacting water flow for a second time. The liquid can be diverted through the dispersion hole 12 to reduce the local pressure. At the same time, it can eliminate the eddies caused by the turbulent water flow. When the baffle 11 is impacted, it will squeeze the second spring 10. The stability of the top of the baffle 11 is improved by the second stabilizing rod 9. When the water flow pushes the baffle 11 to compress the second spring 10, the elastic force of the second spring 10 acts in the opposite direction on the baffle 11, further absorbing some of the impact energy of the water flow. At the same time, the second spring 10 rebounds to reset the baffle 11, adapting to the continuous fluctuation of the water flow impact. The water flow state changes from "concentrated impact" to "uniform diffusion," flowing smoothly into the water supply tank. Mounting plate 1 has mounting holes around its perimeter, and the corresponding holes 2 correspond to the water inlet pipe of the negative pressure water supply tank. In this embodiment, the mounting plate 1 can be easily fixed to the top of the inner cavity of the negative pressure water supply tank through the mounting hole, and the liquid entering through the corresponding hole 2 can directly impact the buffer plate 5 through the middle of the corresponding hole 2 to buffer and improve the buffering effect. It is worth noting that both the second spring 10 and the first spring 7 have anti-corrosion coatings on their surfaces, which can prevent the second spring 10 and the first spring 7 from being affected by rust and thus their cushioning effect. As this is existing technology, it will not be elaborated further.

[0019] The working principle of this utility model is as follows: When in use, select an appropriate size mounting plate 1 according to the diameter of the negative pressure water supply tank, and align the corresponding hole 2 with the water inlet pipe of the tank so that the mounting plate 1 is fixed on the top of the inner cavity of the negative pressure water supply tank. When water flows into the inside of the negative pressure-free water supply tank, it will automatically impact the buffer plate 5 through the corresponding hole 2. The deformation of the buffer plate 5 and the compression of the first spring 7 by the pressure plate 6 driven by the buffer plate 5 can convert the impact kinetic energy of the water flow into the elastic potential energy of the spring, absorb most of the impact energy, reduce the water flow pressure, and the inclined buffer plate 5 can guide the water flow to one side of the baffle 11. Then the water flow impacts the baffle 11 and pushes the baffle 11 to squeeze the second spring 10, further absorbing the impact energy and reducing the impact force of the water flow. At the same time, the water flow is divided into multiple small water flows through the dispersion hole 12, reducing the water flow rate and allowing the water flow to flow smoothly into the water supply tank, thus achieving the buffering effect.
