Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, specifically to a pipeline water supply filtration device. Background Technology

[0002] Urban water supply mainly draws surface water, reservoirs, rivers, lakes, and groundwater from water plants' intake pumping stations. After treatment processes such as sedimentation, disinfection, and filtration, the water is distributed to users through distribution pumping stations and pipeline networks. However, impurities often accumulate in the water supply pipelines during circulation. These impurities primarily originate from: long-term sedimentation of small amounts of impurities in tap water; corrosion and flaking from aging water pipes; and water deterioration in poorly circulating pipelines.

[0003] Patent CN 111167212 A discloses a filtration system for a drainage pipe, including a filtration mechanism disposed within the pipe body. A first water pressure sensor and a second water pressure sensor are respectively disposed on both sides of the filtration mechanism on the pipe body. Both the first and second water pressure sensors are connected to a detection and analysis control mechanism via data cables. The detection and analysis control mechanism determines whether the filtration mechanism is blocked by comparing the water pressure of the first and second water pressure sensors.

[0004] However, the device still has the following problems: although it can detect the blockage of the filter mechanism, the above structure cannot effectively clean the filter screen. When the filter screen is blocked, the drain pipe needs to be removed before the filter mechanism can be cleaned, which is not conducive to rapid water supply. Utility Model Content

[0005] To address the problems existing in the prior art, a pipeline water supply filtration device is provided. This device is easy to operate; by rotating the filter screen and simultaneously opening the slag outlet, backwashing of the filter screen can be achieved, effectively reducing filter screen clogging and cleaning up debris trapped in the water supply pipe. It does not require disassembling the water supply pipe, and offers excellent filtration effect and high filtration efficiency.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] This utility model proposes a pipeline water supply filtration device, including a water supply pipe, a filter screen rotatably connected to the water supply pipe, a water stop plate for sealing the water supply pipe inside the water supply pipe, and a slag outlet located between the filter screen and the water stop plate in the water supply pipe; after the water stop plate seals the water supply pipe, it can release the restriction of the filter screen, at which time the filter screen can rotate freely.

[0008] Preferably, the water supply pipe is rotatably connected to a rotating shaft, one end of which extends into the water supply pipe and is fixedly connected to the filter screen, and a sealing ring is provided at the connection between the rotating shaft and the water supply pipe.

[0009] Preferably, the rotating shaft has a locking hole, and a locking rod that can slide into the locking hole is slidably connected inside the water supply pipe.

[0010] Preferably, the inner wall of the water supply pipe is slidably connected to an inclined block, the inclined block is connected to the inner wall of the water supply pipe via a spring, and a magnet that attracts the inclined block is connected to the clamp rod.

[0011] Preferably, a baffle is slidably connected inside the slag outlet, and the waterstop plate has an insertion hole for the baffle to slide into.

[0012] Preferably, when the baffle slides into the slag outlet to block the slag outlet, the baffle abuts against the surface of the waterstop plate.

[0013] Preferably, when the waterstop plate blocks the water supply pipe, the baffle slides into the insertion hole to open the slag outlet and simultaneously limit the position of the waterstop plate.

[0014] Preferably, the waterstop plate and the water supply pipe are rotatably connected, and a handwheel is fixedly connected to one end of the waterstop plate after it extends out of the water supply pipe. The waterstop plate is also fixedly connected to a pusher block that can push the inclined block to move.

[0015] Preferably, the waterstop plate and the water supply pipe are slidably connected. The waterstop plate has a horizontal groove and a vertical groove that are interconnected. A slider is slidably connected to the outer wall of the water supply pipe. The slider is rotatably connected to a limiting rod that can slide into the horizontal groove. The limiting rod is fixedly connected to a vertical rod that can slide into the vertical groove.

[0016] Preferably, the slag outlet is also threadedly connected to a sealing cap.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model features a rotatable filter screen. The spring force drives the inclined block to move, and the inclined block, through a magnet, drives the locking rod to slide into the locking hole of the rotating shaft, thereby locking the filter screen. Only when the water stop plate blocks the water supply pipe will the water stop plate drive the inclined block to move, and the inclined block will drive the locking rod to release the limit on the filter screen. The operation is convenient. By rotating the filter screen and opening the slag outlet at the same time, the filter screen can be backwashed, thereby effectively reducing the clogging of the filter screen and cleaning the debris intercepted in the water supply pipe. There is no need to disassemble the water supply pipe, resulting in excellent filtration effect and high filtration efficiency.

[0019] 2. This utility model is equipped with a baffle. When the water-stop plate does not block the water supply pipe, the baffle and the surface of the water-stop plate are in contact, and the baffle cannot move. Therefore, the slag outlet will not be opened. Only when the water-stop plate blocks the water supply pipe can the baffle move into the insertion hole of the water-stop plate. The baffle can block or open the slag outlet on the one hand, and support and limit the water-stop plate on the other hand. Thus, when the slag outlet is open, the water supply pipe is always blocked, improving the overall reliability of the device and preventing the mechanism from being accidentally opened due to accidental contact or other reasons.

[0029] The embodiments of this utility model are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary.

[0030] like Figures 1-2As shown, this embodiment proposes a pipeline water supply filtration device, including a water supply pipe 1, which can be connected to a water tank or other equipment that needs to transport water. A filter screen 3 is rotatably connected to the water supply pipe 1, and a water stop plate 12 for sealing the water supply pipe 1 is provided inside the water supply pipe 1. The water supply pipe 1 has a slag outlet 9 located between the filter screen 3 and the water stop plate 12.

[0031] The water supply pipe 1 includes a water passage, a filter screen 3 located in the water passage to intercept debris in the water flow, the filter screen 3 is set at the water inlet end of the water supply pipe 1, and the water stop plate 12 is located at the water outlet end of the water supply pipe 1. The water supply pipe 1 is also connected to a flange 2, which facilitates the connection between the water supply pipe 1 and the water tank or water demand pipeline. The water stop plate 12 is used to seal the water supply pipe 1.

[0032] Since the slag outlet 9 is located between the filter screen 3 and the water stop plate 12, when the slag outlet 9 is opened, the filter screen 3 rotates, which can cause the garbage on the water-facing side of the filter screen 3 to be flipped between the filter screen 3 and the water stop plate 12. When water is supplied at this time, the filter screen 3 can be backwashed, and the cleaned garbage flows out through the slag outlet 9.

[0033] After the water stop plate 12 blocks the water supply pipe 1, it can release the limit of the filter screen 3. At this time, the filter screen 3 can rotate freely. When the water stop plate 12 does not block the water supply pipe 1, the filter screen 3 cannot rotate. Therefore, the filter screen 3 will not rotate due to accidental contact or other reasons, effectively preventing the garbage intercepted by the filter screen 3 from flowing into the water tank or water supply pipeline.

[0034] A rotating shaft 20 is rotatably connected to the water supply pipe 1. One end of the rotating shaft 20 extends into the water supply pipe 1 and is fixedly connected to the filter screen 3. The upper end of the rotating shaft 20 extends out of the water supply pipe 1 and is fixedly connected to a handle. The handle allows the rotating shaft 20 to be easily rotated, which in turn drives the filter screen 3 to rotate. A sealing ring is provided at the connection between the rotating shaft 20 and the water supply pipe 1. The sealing ring serves to seal and reduce the possibility of water leakage at the connection of the rotating shaft 20.

[0035] The rotating shaft 20 has a locking hole 4. A locking rod 5 that can slide into the locking hole 4 is slidably connected inside the water supply pipe 1. The locking rod 5 can only slide in the horizontal direction. The locking rod 5 is set inside the pipe wall of the water supply pipe 1. The locking rod 5 does not contact the water passage inside the water supply pipe. When the locking rod 5 slides into the locking hole 4, it can limit the rotating shaft 20. At this time, the rotating shaft 20 cannot rotate.

[0036] An inclined block 7 is slidably connected to the inner wall of the water supply pipe 1. The inclined block 7 is connected to the inner wall of the water supply pipe 1 by a spring 8. A magnet 6 that attracts the inclined block 7 is connected to the lever 5.

[0037] The left end of spring 8 is connected to the inclined block 7, and the right end of spring 8 is connected to the inner wall of water supply pipe 1. The elastic force of spring 8 is appropriate. In the initial state, under the action of the elastic force of spring 8, spring 8 drives the locking rod 5 to move through magnet 6. The locking rod 5 is inserted into the locking hole 4 to limit the rotation shaft 20. In order to reduce the impact of water flow on the inclined block 7, a water blocking block can also be provided on the inner wall of water supply pipe 1. The water blocking block is located between filter screen 4 and inclined block 7.

[0038] A baffle 11 is slidably connected inside the slag outlet 9. The water stop plate 12 has an insertion hole 14 for the baffle 11 to slide into. The baffle 11 can only slide in the horizontal direction. The baffle 11 is slidably connected to the outer wall of the water supply pipe 1. One end of the baffle 11 can slide into the slag outlet 9 to block the slag outlet 9.

[0039] A push rod is fixedly connected to one end of the baffle 11 located on one side of the slag outlet 9. The push rod is designed to facilitate the horizontal movement of the baffle 11, thereby pushing the baffle 11 into the slag outlet 9 to block the slag outlet 9. The baffle 11 is pushed outward and slides into the insertion hole 14 of the water stop plate 12, which can open the slag outlet 9. At the same time, the baffle 11 limits and supports the water stop plate 12.

[0040] When the baffle 11 slides into the slag outlet 9 to block the slag outlet 9, the baffle 11 abuts against the surface of the waterstop plate 12. At this time, the baffle 11 cannot move horizontally, so the slag outlet 9 cannot be opened. When the waterstop plate 12 blocks the water supply pipe 1, the baffle 11 slides into the insertion hole 14 to open the slag outlet 9 and simultaneously limit the waterstop plate 12. At this time, the waterstop plate 12 cannot move vertically, so the water supply pipe 1 is always in a blocked state.

[0041] When the water stop plate 12 does not block the water supply pipe 1, the baffle 11 and the surface of the water stop plate 12 are in contact, and the baffle 11 cannot move. Therefore, the slag outlet 9 will not be opened. Only when the water stop plate 12 blocks the water supply pipe 1 can the baffle 11 move into the insertion hole 14 of the water stop plate 12. The baffle 11 can block or open the slag outlet 9 on the one hand, and support and limit the water stop plate 12 on the other hand. This ensures that when the slag outlet 9 is open, the water supply pipe 1 is always blocked, improving the overall reliability of the device and preventing accidental opening of the mechanism due to accidental contact or other reasons.

[0042] The waterstop plate 12 and the water supply pipe 1 are rotatably connected. One end of the waterstop plate 12 extends out of the water supply pipe 1 and is fixedly connected to a handwheel. The waterstop plate 12 is fixedly connected to a push block 19 that can push the inclined block 7 to move. The waterstop plate 12 has two states. When it is in state one, the waterstop plate 12 is parallel to the water flow direction. At this time, the water supply pipe 1 is open, and the baffle 11 abuts against the surface of the waterstop plate 12. When it is in state two, the waterstop plate 12 is perpendicular to the water flow direction, thus blocking the water supply pipe 1. At this time, the insertion hole 14 moves to one side of the baffle 11, and the baffle 11 can slide into the insertion hole 14 to limit the waterstop plate 12. At this time, the waterstop plate 12 cannot rotate. At the same time, during this process, the waterstop plate 12 pushes the inclined block 7 to move through the push block 19, thus releasing the limitation on the rotating shaft 20.

[0043] The slag outlet 9 is also threadedly connected to a sealing cap 10. The slag outlet 9 can be opened by unscrewing the sealing cap 10. The sealing sleeve 10 serves to protect the slag outlet 9.

[0044] Example 2

[0045] Reference Appendix Figures 3-6 The other structures are the same as in Embodiment 1. The difference is that in this embodiment, the water-stopping problem of water supply pipes of different shapes is taken into account.

[0046] The waterstop plate 12 and the water supply pipe 1 are slidably connected. The water supply pipe 1 can slide downward from the lower end of the waterstop plate 12. The waterstop plate 12 has a horizontal groove 16 and a vertical groove 17 that are interconnected. A slider is slidably connected to the outer wall of the water supply pipe 1. The slider is rotatably connected to a limiting rod 18 that can slide into the horizontal groove 16. The limiting rod 18 is fixedly connected to a vertical rod that can slide into the vertical groove 17.

[0047] The waterstop plate 12 is fixedly connected to the limiting block 15, which is located inside the water supply pipe 1. The setting of the limiting block 15 prevents the waterstop plate 12 from completely moving out of the water supply pipe 1, thereby limiting the movement of the water supply pipe 1. In the initial state, the limiting rod 18 first drives the vertical rod to slide into the horizontal groove 16. Then, by rotating the limiting rod 18, the vertical rod can slide into the vertical groove 17, thereby limiting the waterstop plate 12 when it is not sealed.

[0048] The specific working process is as follows: When using the method described in Embodiment 1, by rotating the waterstop plate 12, the waterstop plate 12 is made perpendicular to the water flow direction, thereby blocking the water supply pipe 1. At this time, the insertion hole 14 moves to the side of the baffle 11. When using the method described in Embodiment 2, by rotating the limiting rod 18, the vertical rod is rotated upward out of the vertical groove 17. At this time, the limiting rod 18 is pulled outward, so that the limiting rod 18 moves out of the horizontal groove 16 and pushes the waterstop plate 12 upward, thereby blocking the water supply pipe 1.

[0049] By moving the baffle 11, the baffle 11 slides into the insertion hole 14, opening the slag outlet 9 and limiting the water stop plate 12. At this time, the water stop plate 12 cannot rotate. Simultaneously, during this process, the water stop plate 12 pushes the inclined block 7 through the push block 19, releasing the limitation on the rotating shaft 20. The rotating shaft 20 drives the filter screen 3 to rotate, causing the garbage on the water-facing side of the filter screen 3 to be flipped between the filter screen 3 and the water stop plate 12. Then, the sealing cap 10 is unscrewed. When water is supplied again, the filter screen 3 can be backwashed, and the cleaned garbage flows out through the slag outlet 9.
