Description

Technical Field

[0001] This invention relates to the field of water purification tanks, and in particular to a novel lightweight water purification tank. Background Technology

[0002] As people's living standards continue to improve, they also have higher requirements for drinking water quality. Water purification tanks are water storage structures equipped with filtration devices, commonly used in transportation vehicles such as trains, high-speed trains, and airplanes to provide healthy and clean drinking water for passengers.

[0003] A related technology discloses a water purification tank for high-speed rail, comprising a hollow tank body with multiple partitions inside to divide its interior into several zones. Each partition has multiple through holes. The partitions impede and intercept the flow of drinking water within the tank, reducing the likelihood of the drinking water impacting the tank's side walls due to the start and stop of the high-speed train, thus preventing tank deformation.

[0004] When the water tank is full, the impact of the drinking water inside on the tank is relatively small. However, as the drinking water is used, the impact of the remaining drinking water on the tank increases, indicating a significant drawback. Summary of the Invention

[0005] To address the issue of drinking water impacting the tank, this application provides a novel lightweight water purification tank.

[0006] The novel lightweight water purification tank provided in this application adopts the following technical solution:

[0007] A novel lightweight water purification tank includes a hollow tank body. One side of the tank body is connected to a water injection pipe and a water supply pipe. A sliding plate is provided inside the tank body. The sliding plate is in close contact with and slidably engaged with the inner wall of the tank body. A vent is provided on the side of the tank body opposite the sliding plate and facing away from the water injection pipe.

[0008] By adopting the above technical solution, when water is supplied from the water supply pipe, the drinking water in the tank gradually decreases, and outside air enters the tank through the vent, thereby pushing the slide plate to move closer to the water supply pipe. In this way, the remaining drinking water in the tank is concentrated in the cavity enclosed by the slide plate and the tank. Since the drinking water always fills the cavity, the impact of drinking water on the space is less when it is fully loaded, thus extending the service life of the tank.

[0009] Optionally, the slide plate is slidably provided with multiple partitions on one side relative to the water injection pipe. Multiple through holes are provided on the partitions. Magnetic strips with magnetic repulsion are respectively provided on the slide plate and the nearest partition, two adjacent partitions, and the side of the box body connected to the water injection pipe and the nearest partition.

[0010] By adopting the above technical solution, as the drinking water in the tank gradually decreases, under the action of external atmospheric pressure, multiple partitions and sliding plates overcome the magnetic repulsion force of the magnetic strips and move towards the water supply pipe, and the distance between two adjacent partitions gradually decreases. When water is injected into the tank through the water injection pipe, multiple partitions and sliding plates gradually move away from the water supply pipe under the action of magnetic repulsion force to achieve resetting.

[0011] Optionally, except for the partition closest to the skateboard, the other partitions are all hinged with top rods near both ends on the side opposite the skateboard. The top rods are hinged with sliders at the other end of the partitions they are on. Except for the partition farthest from the skateboard, the other partitions have grooves parallel to the partitions on the side facing away from the skateboard. The sliders are located in the grooves on the adjacent partitions and slide with them. The top rods and the sliding direction of the skateboard have an angle between them.

[0012] By adopting the above technical solution, as multiple partitions approach the water supply pipe, the distance between adjacent partitions gradually decreases, allowing the push rod to rotate relative to its respective partition, while the slider slides within its corresponding groove. The push rod and slider design integrate multiple partitions and sliding plates into a single unit, thereby reducing the possibility of the partitions and sliding plates tipping over during sliding.

[0013] Optionally, the box is provided with an internally hollow elastic airbag, the open end of which is located at the vent, and the cavity between the elastic airbag and the slide plate inside the box is in a vacuum state.

[0014] By employing the above technical solution, the elastic airbag inflates when air enters through the vent and contracts when air exits through the vent. The elastic airbag reduces the likelihood of impurities from the outside air remaining inside the tank, thus minimizing the possibility of contaminating the drinking water.

[0015] Optionally, each baffle is fixedly provided with multiple turbulence cones, the axis of the inlet end of the turbulence cone is perpendicular to the length direction of the baffle, the axis of the outlet end of the turbulence cone is parallel to the length direction of the baffle, and the inner diameter of the turbulence cone gradually decreases along the direction from its inlet end to its outlet end.

[0016] By adopting the above technical solution, when drinking water causes an impact, the drinking water in the tank body flows in from the inlet end of the turbulence cone and flows out from the outlet end of the turbulence cone, causing a lateral impact on the remaining drinking water. This disrupts the impact direction of the drinking water on the tank body, thereby distributing the impact force of the drinking water to the side walls of the tank body that are not impacted, thus improving the impact resistance of the tank body.

[0017] Optionally, two water injection pipes are connected on the box body, and two splash guards with bottom openings are provided on the top wall of the box body. Each splash guard corresponds to one water injection pipe and the splash guard is sleeved on the end of the corresponding water injection pipe located inside the box body.

[0018] By adopting the above technical solution, the splash-proof shell reduces the possibility that drinking water in the tank will splash into another water injection pipe when any one water injection pipe is used for single water injection.

[0019] Optionally, each turbulence cone has a bearing ring coaxially arranged at its water inlet end. An arc support is provided between the bearing ring and the water inlet end of the turbulence cone. An elastic bladder tube is connected between the bearing ring and the water inlet end of the turbulence cone. Multiple elastic plates are arranged circumferentially inside the bearing ring. Two adjacent elastic plates are in close contact. The multiple elastic plates are joined together to form a cone shape with the cone tip pointing towards the corresponding turbulence cone.

[0020] By adopting the above technical solution, the laterally turbulent drinking water pushes open the elastic sheet and flows into the elastic capsule through the gap between multiple elastic sheets, which quickly expands it. The deformation force of the elastic capsule can apply a thrust when the drinking water is sprayed out from the outlet of the turbulence cone, thereby further enhancing the disturbance effect of the turbulence cone on the drinking water.

[0021] Optionally, both the partition and the slide plate are coated with polytetrafluoroethylene.

[0022] By adopting the above technical solution, polytetrafluoroethylene has a low coefficient of friction, so the partitions and slides can move relatively smoothly inside the box.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. When water is supplied from the water supply pipe, the drinking water in the tank gradually decreases. Outside air enters the tank through the vent, which pushes the slide plate towards the water supply pipe. In this way, the remaining drinking water in the tank is concentrated in the cavity enclosed by the slide plate and the tank. Since the drinking water always fills the cavity, the impact of drinking water on the space is less when the space is fully loaded, thus extending the service life of the tank.

[0025] 2. When drinking water impacts the tank, the drinking water inside the tank flows in from the inlet end of the baffle cone and flows out from the outlet end of the baffle cone, causing a lateral impact on the remaining drinking water. This disrupts the impact direction of the drinking water on the tank and distributes the impact force of the drinking water to the side walls of the tank that are not impacted, thereby improving the impact resistance of the tank.

[0032] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0033] This application discloses a novel lightweight water purification tank.

[0034] Reference Figure 1 The new lightweight water purification tank includes a hollow, rectangular tank body 1, which is made of titanium alloy and has high structural strength. The tank body 1 is wrapped with an insulation layer (not shown in the figure), which can reduce the heat loss of the drinking water inside the tank body 1, thereby meeting the needs of passengers for hot water.

[0035] Reference Figure 1 One end of the tank 1 along its length is connected to a water supply pipe 3 and two water injection pipes 2. The water injection pipes 2 are used to replenish drinking water into the tank 1, and are also equipped with filter valves (not shown in the figure) for filtering the drinking water. When passengers need to drink water, they can draw drinking water from the tank 1 through the water supply pipe 3.

[0036] Reference Figure 2 Two splash guards 11 with bottom openings are welded to the top wall of the inner box 1. Each splash guard 11 corresponds to a water injection pipe 2 and the splash guard 11 is sleeved on the end of the corresponding water injection pipe 2 located inside the box 1.

[0037] The splash guard 11 is used to reduce the possibility that drinking water in the tank 1 will splash into the other water pipe 2 when either water pipe 2 is being filled.

[0038] Reference Figure 2 A continuous level gauge 16 is bolted inside the tank 1 near the water supply pipe 3. The continuous level gauge 16 is electrically connected to the control system. The continuous level gauge 16 can detect the water level in the tank. When the water level reaches the set threshold, the continuous level gauge 16 will send a signal to stop water injection.

[0039] Reference Figure 1 and Figure 2 The tank 1 is also connected to an overflow pipe 17. When the water level in the tank 1 exceeds the set threshold, the excess drinking water can be discharged in time through the overflow pipe 17.

[0040] An emptying pipe 18 is connected to the outside of the tank 1, and an overflow pipe 17 is connected to the emptying pipe 18. A solenoid valve 19 electrically connected to the control system is installed on the emptying pipe 18. When the vehicle stops operating, the control system opens the solenoid valve 19 to empty the remaining drinking water in the tank 1.

[0041] Reference Figure 1 and Figure 2 The bottom of the tank 1 is open and a bottom cover 20 is bolted to the opening. When the solenoid valve 19 is damaged, the worker can manually open the bottom cover 20 to drain the drinking water in the tank 1.

[0042] Reference Figure 1 and Figure 3 The box 1 is equipped with a slide plate 4, which is parallel to the width direction of the box 1. The slide plate 4 is in close contact with the inner wall of the box 1 and slides in fit. The box 1 has a vent hole 101 on the side of the box 1 opposite to the slide plate and facing away from the water injection pipe 2.

[0043] Reference Figure 1 and Figure 3 When the drinking water in the tank 1 is discharged through the water supply pipe 3, the outside air will not enter between the slide plate 4 and the water supply pipe 3. Under the action of atmospheric pressure, the slide plate 4 moves towards the water supply pipe 3, and at the same time, the outside air enters the tank 1 through the vent 101.

[0044] Conversely, when the water inlet pipe 2 fills the tank 1 with water, the drinking water pushes the slide plate 4 to move away from the water supply pipe 3, and the air on the side of the slide plate 4 facing away from the water supply pipe 3 inside the tank 1 is discharged through the vent 101.

[0045] Reference Figure 1 and Figure 3 With the above structure, as drinking water is used, the drinking water in the tank 1 is concentrated in the gradually decreasing space formed by the slide plate 4 and the tank 1. The drinking water always fills this space, thereby reducing the impact of drinking water on the tank 1 and extending the service life of the tank 1.

[0046] In addition, when drinking water impacts the slide plate 4, the slide plate 4 can overcome atmospheric pressure and move slightly away from the water supply pipe 3. After the impact ends, the slide plate 4 moves back under the action of atmospheric pressure. In this way, the slide plate 4 can eliminate the impact of drinking water in a flexible way.

[0047] Reference Figure 1 , Figure 3 and Figure 4 Multiple baffles 5 are slidably disposed on one side of the slide plate 4 relative to the water supply pipe 2. The multiple baffles 5 are arranged along the direction from the slide plate 4 to the water supply pipe 3 and are parallel to the slide plate 4.

[0048] Each slide plate 4 has multiple through holes 51. Magnetic strips 6 that repel each other are fixedly installed on one side of the slide plate 4, the nearest partition plate 5, the two adjacent partition plates 5, the water injection pipe 2 of the connecting pipe of the box body 1, and the nearest partition plate 5, respectively.

[0049] Reference Figure 1 , Figure 3 and Figure 4 As the slide plate 4 gradually approaches the water supply pipe 3, the force on each partition 5 gradually approaches the water supply pipe 3, and the distance between two adjacent partitions 5 gradually decreases.

[0050] The partition 5 can obstruct and intercept the flow of drinking water in the space formed by the slide plate 4 and the box 1, thereby reducing the possibility of drinking water impacting the slide plate 4 and the box 1.

[0051] As the slide plate 4 moves away from the water supply pipe 3, the repulsive force between the magnetic strips 6 will push each partition 5 away from the water supply pipe 3, and the distance between two adjacent partitions 5 will gradually increase.

[0052] As the slide plate 4 moves away from and towards the water supply pipe 3, multiple baffles 5 can be relatively evenly distributed in the space formed by the slide plate 4 and the box 1, thereby ensuring the obstruction effect on the flow of drinking water.

[0053] Reference Figure 1 , Figure 3 and Figure 4 Both the partition 5 and the slide plate 4 are coated with polytetrafluoroethylene (PTFE). PTFE has a low coefficient of friction, so the partition 5 and the slide plate 4 can slide smoothly within the box 1.

[0054] Reference Figure 1 , Figure 3 and Figure 4 The box 1 is also equipped with an internally hollow elastic airbag 9. The open end of the elastic airbag 9 is attached to the vent 101. The cavity between the elastic airbag 9 and the slide plate 4 inside the box 1 is in a vacuum state.

[0055] When the slide plate 4 approaches the water supply pipe 3, outside air enters the elastic airbag 9 and inflates it. When the slide plate 4 moves away from the water supply pipe 3, the air in the elastic airbag 9 is expelled again. The elastic airbag 9 can reduce the possibility of impurities in the outside air remaining in the tank 1, thus improving the drinking water quality.

[0056] Reference Figure 1 , Figure 3 and Figure 4 Except for the partition 5 closest to the skateboard 4, the other partitions 5 are all hinged with top rods 7 on the side of the skateboard 4 near both ends. The top rods 7 are hinged with sliders 8 on the other end of the partition 5 they are on.

[0057] Except for the partition 5 furthest from the slide plate 4, the other partitions 5 have grooves 52 parallel to the partition 5 on the side facing away from the slide plate 4. The slider 8 is located in the groove 52 on the adjacent partition 5 and slides with it. The longitudinal section of the slider 8 and the groove 52 are both dovetail shaped. There is an angle between the sliding direction of the top rod 7 and the sliding direction of the slide plate 4.

[0058] Reference Figure 1 , Figure 3 and Figure 4 When the partition 5 and the slide plate 4 move, they move within the corresponding groove 52. The push rod 7 and the slider 8 connect the multiple partitions 5 and the slide plate 4 into a single unit, thereby reducing the possibility of the partitions 5 and the slide plate 4 tipping over during movement.

[0059] Reference Figure 1 , Figure 4 and Figure 5 Each baffle 5 is fixedly provided with multiple turbulence cone tubes 10. The axis of the water inlet end of the turbulence cone tube 10 is perpendicular to the length direction of the baffle 5, and the axis of the water outlet end of the turbulence cone tube 10 is parallel to the length direction of the baffle 5. The inner diameter of the turbulence cone tube 10 gradually decreases along the direction from its water inlet end to its water outlet end.

[0060] Reference Figure 1 , Figure 4 and Figure 5 When drinking water impacts due to inertia, the drinking water inside the tank 1 flows in from the inlet end of the turbulence cone 10 and flows out from the outlet end of the turbulence cone 10.

[0061] The drinking water flowing out from the outlet can cause a lateral impact on the remaining drinking water, thereby disrupting the impact direction of the drinking water on the tank 1. This distributes the impact received by the slide plate 4 and the side wall of the tank 1 in the length direction to the side wall in the width direction, thereby improving the impact resistance of the tank 1.

[0062] The gradually changing inner diameter of the turbulence cone 10 also increases the lateral turbulence intensity of drinking water, thereby further enhancing the disturbance effect on drinking water.

[0063] Reference Figure 1 , Figure 4 and Figure 5 Each turbulence cone 10 has a bearing ring 12 coaxially arranged at its water inlet end. Two arc supports 13 are circumferentially welded between the bearing ring 12 and the water inlet end of the turbulence cone 10. An elastic bladder tube 14 connects the bearing ring 12 and the water inlet end of the turbulence cone 10.

[0064] Multiple elastic sheets 15 are bonded to the inner circumference of the bearing ring 12. Two adjacent elastic sheets 15 are tightly attached to each other in the circumferential direction. The multiple elastic sheets 15 are assembled into a cone shape with the cone tip pointing towards the corresponding turbulence cone tube 10.

[0065] Reference Figure 1 , Figure 4 and Figure 5 The lateral turbulence of drinking water pushes open the elastic sheet 15 and flows into the elastic bladder tube 14 through the gap between the multiple elastic sheets 15, which quickly expands it. The deformation force of the elastic bladder tube 14 can apply a thrust when the drinking water is sprayed out from the outlet end of the turbulence cone tube 10, thereby further enhancing the turbulence effect of the turbulence cone tube 10 on the drinking water.

[0066] The implementation principle of a novel lightweight water purification tank in this application embodiment is as follows:

[0067] When the drinking water in the tank 1 is discharged through the water supply pipe 3, the slide plate 4 moves towards the water supply pipe 3 under the action of atmospheric pressure. Each partition 5 is gradually brought closer to the water supply pipe 3, and the distance between two adjacent partitions 5 gradually decreases. At the same time, outside air enters the elastic airbag 9 through the vent 101.

[0068] When drinking water impacts the tank 1, the laterally turbulent drinking water pushes open the elastic sheet 15 and flows into the elastic bladder tube 14 through the gap between multiple elastic sheets 15, which quickly expands it. The deformation force of the elastic bladder tube 14 pushes the drinking water out of the outlet end of the turbulence cone tube 10, thereby causing a lateral impact on the remaining drinking water. This disrupts the impact direction of the drinking water on the tank 1, and thus distributes the impact of the slide plate 4 and the side wall of the tank 1 in the length direction to the side wall in the width direction.

[0069] When the water inlet pipe 2 fills the tank 1 with water, the drinking water pushes the slide plate 4 and the partition 5 to move away from the water supply pipe 3. The distance between two adjacent partitions 5 gradually increases, and the air in the elastic airbag 9 is squeezed out of the tank 1 again.

[0070] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
