Description

Technical Field

[0001] The present application relates to the field of garden water circulation, and in particular to a garden water circulation system. Background Art

[0002] Gardens occupy an important position in urban architecture and have become an important criterion for measuring whether a city is livable. Therefore, at this stage, most cities are stepping up the construction of gardens to enhance the image of the city. Gardening is an important part of garden construction. When it rains outside and the green belt is irrigated, a water circulation structure is generally set up to purify and recycle the liquid. By circulating the liquid, water resources can be saved and the utilization rate of water resources can be improved.

[0003] With respect to the above-mentioned related technologies, the inventors believe that the water circulation equipment in the prior art generally has a water collection pool for storing rainwater, and then the collected liquid is stored inside the water collection pool through a pipe, and the liquid inside the water collection pool is pumped back to the greening location by a pump body. However, when the amount of liquid is small and the overall greening pipeline is long, the liquid inside the pipeline is not easy to flow to the greening location. Summary of the invention

[0004] In order to facilitate the diversion of liquid at the greening location, increase the flow distance of the liquid inside the pipeline, reduce the amount of small flow liquid inside the pipeline and thus reduce the irrigation effect, the present application provides a garden water circulation system.

[0005] The present application provides a garden water circulation system, which adopts the following technical solutions:

[0006] A garden water circulation system includes a water storage tank, a water outlet is provided at the bottom end of the water storage tank, a sealing plate is provided to block the position of the water storage tank relative to the water outlet, an air bag is arranged inside the water storage tank, a first elastic member is fixedly connected to the bottom end of the air bag, the first elastic member is fixedly connected to the water storage tank, a draw rope is fixedly connected to the bottom end of the water storage tank, the draw rope is fixedly connected to the sealing plate, and a fixing structure for fixing the air bag is arranged at the top end of the water storage tank.

[0007] By adopting the above technical solution, when external liquid enters the interior of the water storage tank, the liquid inside the water storage tank drives the airbag to move upward, the airbag drives the pull rope to move upward, and then the pull rope drives the sealing plate to detach from the water outlet, so that the liquid inside the water storage tank is discharged from the water outlet, and the airbag can be fixed by the set fixing structure, and then the liquid inside the water storage tank is discharged at one time, which is convenient for guiding the liquid at the greening position, and increasing the flow distance of the liquid inside the pipeline, reducing the amount of small flow liquid inside the pipeline, thereby reducing the irrigation effect.

[0008] Optionally, the card fixing structure includes a vertically arranged water guide pipe. A spring hole is horizontally formed in the side wall of the water guide pipe. A ball is slidably connected inside the spring hole. A second elastic member is horizontally arranged at one end of the ball close to the spring hole. A jack is concavely arranged at the position of the top end of the airbag relative to the water guide pipe. A limiting hole is horizontally concavely arranged inside the jack at the position relative to the spring hole. When the water guide pipe is located inside the jack, the ball extends into the limiting hole.

[0009] By adopting the above technical solution, when the liquid inside the water storage tank drives the airbag to move upward, the water guide pipe then extends into the jack, and then the ball is aligned with the limiting hole, so that the ball extends into the limiting hole, relatively fixing the airbag and the water guide pipe. And when the liquid located inside the water storage tank is drained, the airbag moves downward under the action of gravity and the pulling force of the first elastic member, and then the ball and the limiting hole are relatively disengaged.

[0010] Optionally, an overflow port is horizontally formed in the side wall of the water guide pipe. An overflow plate is vertically arranged at the position of the water guide pipe relative to the overflow port. The overflow plate can completely cover the overflow port. A third elastic member is fixedly connected to one end of the overflow plate close to the water guide pipe. A detector is fixedly connected to the bottom wall of the water storage tank at the position relative to the water outlet. The detector can detect whether the sealing plate is located inside the water outlet. A lifting structure is arranged below the airbag. The lifting structure can push the airbag upward.

[0011] By adopting the above technical solution, after the water guide pipe extends into the jack, the liquid located inside the purification part cannot enter the water accumulation part from the position of the water guide pipe. And when the liquid inside the purification part is too much, by pushing the overflow plate to the side away from the water guide pipe, the liquid located inside the water guide pipe is discharged into the water accumulation part from the position of the overflow port. And the airbag is moved upward by the lifting structure. Then the airbag drives the sealing plate to move upward through the pull rope, thereby increasing the gap between the sealing plate and the water outlet and accelerating the discharge of the liquid located inside the water accumulation part.

[0012] Optionally, the lifting structure includes relatively arranged lifting blocks. The top wall of the lifting block is inclined and gradually inclines upward from the relatively close side to the relatively far side. A bidirectional lead screw is horizontally arranged below the lifting block. Both ends of the bidirectional lead screw are threadedly connected to the two lifting blocks respectively. A first driving member for driving the bidirectional lead screw to rotate is arranged at one end of the bidirectional lead screw. The first driving member is signal-connected to the detector. An adjustment hole is vertically concavely arranged at the position of the airbag relative to the jack. An adjustment plate is horizontally arranged inside the adjustment hole. The adjustment plate is slidably connected to the airbag. A fourth elastic member is vertically arranged below the adjustment plate.

[0013] By adopting the above technical solution, when the time that the detector detects that the sealing block is not located at the water outlet position exceeds the predetermined time, the detector controls the first driving member to drive the bidirectional lead screw to rotate. Then, the bidirectional lead screw drives the two opposite lifting blocks to move towards or away from each other. Further, the inclined top wall of the lifting block drives the airbag to move upward.

[0014] Optionally, a flexible net is fixedly connected to the sealing plate, and the flexible net is fixedly connected to the water storage tank.

[0015] By adopting the above technical solution, the fixedly arranged flexible net can reduce the backflow of external liquid into the interior of the water storage tank from the position of the water outlet.

[0016] Optionally, a partition plate is horizontally and fixedly connected inside the water storage tank. The partition plate is located above the airbag. A dynamic membrane is fixedly connected to the partition plate. The top end of the water guide pipe extends into the interior of the dynamic membrane and is fixedly connected relatively. A cleaning structure for cleaning the dynamic membrane is arranged on the dynamic membrane.

[0017] By adopting the above technical solution, the arranged dynamic membrane can purify the liquid located inside the purification part, and the purified liquid enters the interior of the water accumulation part through the position of the guide pipe. The cleaning structure can clean the impurities on the surface of the dynamic membrane.

[0018] Optionally, the cleaning structure includes an inner cleaning rod that abuts and slides against the inner side wall of the dynamic membrane and an outer cleaning rod that abuts and slides against the outer side wall of the dynamic membrane. A connecting rod is horizontally arranged at the top ends of the inner cleaning rod and the outer cleaning rod. The connecting rod is fixedly connected to the inner cleaning rod, and the connecting rod is fixedly connected to the outer cleaning rod. One end of the connecting rod is provided with a second driving member for driving the connecting rod to rotate. A drain hole is formed in the side wall of the water storage tank. A baffle is slidably connected to the position of the water storage tank relative to the drain hole. The baffle is connected to the second driving member through a linkage structure. A sedimentation tank is arranged outside the water storage tank.

[0019] By adopting the above technical solution, the second driving member drives the connecting rod to rotate. Then, the connecting rod drives the inner cleaning rod and the outer cleaning rod to rotate. Thus, the inner cleaning rod can clean the inner side wall of the dynamic membrane, and the outer cleaning rod can clean the outer side wall of the dynamic membrane. The cleaned impurities are discharged into the interior of the sedimentation tank through the drain hole for sedimentation and filtration.

[0020] Optionally, the linkage structure includes a vertically arranged linkage rod, the second driving member can drive the linkage rod to rotate, the outer side of the linkage rod is fixedly connected to a limiting block, the outer sliding sleeve of the linkage rod is provided with a linkage sleeve, the inner side wall of the linkage sleeve is provided with a limiting groove, the limiting groove includes a spiral groove, the bottom end of the spiral groove is horizontally provided with a ring groove, the spiral groove is relatively connected to the ring groove, the limiting block is located inside the limiting groove and is relatively slidably connected, the outer side of the linkage sleeve is fixedly connected to a linkage rope, the end of the linkage rope facing away from the linkage sleeve is fixedly connected to the baffle, the linkage rope is provided with a hinged sleeve, and the hinged sleeve is fixedly connected to the water storage tank.

[0021] By adopting the above technical solution, the second driving member drives the linkage rod to rotate, and the linkage rod drives the limit block to slide relatively inside the limit groove, and the limit block slides relatively inside the spiral groove, and the linkage sleeve is moved upward through the limit block, thereby driving the pull rope to move toward the side close to the linkage sleeve, and moving the baffle upward. When the limit block is located inside the annular groove and rotates relatively, the position of the pull rope does not change, and the liquid inside the water storage tank can be continuously discharged into the sedimentation tank.

[0022] Optionally, a return pipe is fixedly connected to the side wall of the sedimentation tank, and the return pipe is relatively connected to the water storage tank. A filter mesh is horizontally arranged inside the sedimentation tank, and a third driving member for driving the filter mesh to move up and down is vertically arranged at the top of the sedimentation tank. An auger is horizontally arranged at the bottom end of the sedimentation tank, and a fourth driving member for driving the auger to rotate is fixedly connected to the position of the sedimentation tank relative to the auger, and a sewage outlet is opened on the side of the sedimentation tank relative to the auger away from the fourth driving member.

[0023] By adopting the above technical solution, the third driving member drives the filter mesh to move downward, thereby separating the precipitated liquid and impurities, and the filtered liquid is returned to the interior of the water storage tank through the return pipe, and the impurities are discharged from the sewage outlet by driving the auger to rotate through the third driving member.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. When the external liquid enters the interior of the water storage tank, the liquid inside the water storage tank drives the airbag to move upward, the airbag drives the pull rope to move upward, and then the pull rope drives the sealing plate to detach from the water outlet, so that the liquid inside the water storage tank is discharged from the water outlet, and the airbag can be fixed by the provided fixing structure, so that the liquid inside the water storage tank can be discharged at one time, which is convenient for guiding the liquid at the greening position, and increasing the flow distance of the liquid inside the pipeline, reducing the amount of small flow liquid inside the pipeline, thereby reducing the irrigation effect.

[0026] 2. After the water conduit extends into the interior of the jack, the liquid inside the purification part cannot enter the interior of the water accumulation part from the position of the water conduit. And when there is too much liquid inside the purification part, by pushing the overflow plate towards the side away from the water conduit, the liquid inside the water conduit is discharged into the interior of the water accumulation part from the position of the overflow port. And through the lifting structure, the airbag is moved upward, and then the airbag drives the sealing plate to move upward through the pull rope, thereby increasing the gap between the sealing plate and the water outlet and accelerating the discharge of the liquid inside the water accumulation part.

[0027] 3. The second driving part drives the linkage rod to rotate. The linkage rod drives the limiting block to slide relatively inside the limiting groove, and the limiting block slides relatively inside the spiral groove. The limiting block moves the linkage sleeve upward, and then drives the pull rope to move towards the side close to the linkage sleeve, moving the baffle upward. When the limiting block rotates relatively inside the annular groove, the position of the pull rope remains unchanged, and then the liquid inside the water storage tank can continue to be discharged into the sedimentation tank.

[0037] The following further describes the present application in detail with reference to the Figures 1-8 accompanying drawings.

[0038] An embodiment of the present application discloses a garden water circulation system. Referring to Figure 1 、 Figure 2 , a garden water circulation system includes a water storage tank 1 vertically arranged inside the ground. The water storage tank 1 is a hollow rectangular structure, and the top of the water storage tank 1 is open. A grate 11 is horizontally and fixedly connected to the top of the water storage tank 1. Through the grate 11, rainwater from the outside can be collected into the interior of the water storage tank 1. A partition 2 is horizontally arranged inside the water storage tank 1. The partition 2 is fixedly connected to the water storage tank 1. The water storage tank 1 is divided into a purification part 3 located above and a water accumulation part 4 located below by the partition 2.

[0039] Referring to Figure 2 、 Figure 3 , the purification part 3 includes a dynamic membrane 31 fixed on the partition 2. The dynamic membrane 31 is a hollow cylindrical structure, and a water guide pipe 32 is fixedly connected to the bottom end of the dynamic membrane 31. The top end of the water guide pipe 32 extends into the interior of the dynamic membrane 31, and the bottom end of the water guide pipe 32 extends out from the position of the partition 2 and extends into the interior of the water accumulation part 4, thereby relatively connecting the interior of the dynamic membrane 31 with the interior of the water accumulation part 4.

[0040] The liquid inside the purification section 3 can enter the inside of the dynamic membrane 31 through the filtration of the dynamic membrane 31 and flow into the inside of the water accumulation section 4 through the water guide pipe 32. The impurities in the liquid inside the purification section 3 will remain on the inner side wall and the outer side wall of the dynamic membrane 31, and a cleaning structure 5 is arranged at the position of the dynamic membrane 31 to clean the surface of the dynamic membrane 31 through the cleaning structure 5.

[0041] The cleaning structure 5 includes an inner cleaning rod 51 vertically arranged on the inner side wall and an outer cleaning rod 52 vertically arranged on the outer side wall. The inner cleaning rod 51 is in contact with and relatively slidably connected to the inner side wall, and the outer cleaning rod 52 is in contact with and relatively slidably connected to the outer side wall. A connecting rod 53 is horizontally arranged at the top of the inner cleaning rod 51 and the outer cleaning rod 52. The connecting rod 53 is fixedly connected to the inner cleaning rod 51 and is fixedly connected to the outer cleaning rod 52.

[0042] A linkage rod 54 is vertically arranged above the dynamic membrane 31. The linkage rod 54 is coaxially arranged with the dynamic membrane 31. A first rotating motor 541 is fixedly connected to the grille 11 relative to the position of the linkage rod 54. The motor shaft of the first rotating motor 541 is coaxially and fixedly connected to the linkage rod 54. The linkage rod 54 is driven to rotate by the first rotating motor 541, and the linkage rod 54 drives the inner cleaning rod 51 and the outer cleaning rod 52 to rotate around the motor shaft of the first rotating motor 541 to clean the surface of the dynamic membrane 31 through the inner cleaning rod 51 and the outer cleaning rod 52.

[0043] An air supply pipe 55 is fixedly connected to the upper surface of the partition plate 2 relative to the inside of the dynamic membrane 31. A plurality of air supply holes 551 are opened on the upper surface of the air supply pipe 55. The air supply holes 551 communicate the inside of the air supply pipe 55 with the inside of the purification section 3. An air supply structure is connected to the outside of the air supply pipe 55 to perform aeration cleaning on the inner side of the dynamic membrane 31 through the air supply pipe 55.

[0044] Refer to Figure 2 、 Figure 4 A drain hole 12 is horizontally opened on the side wall of the purification section 3 where the water storage tank 1 is located, and a baffle 121 is vertically slidably connected to the water storage tank 1 relative to the position of the drain hole 12. When the baffle 121 and the drain hole 12 are opposite, the baffle 121 can completely seal the drain hole 12, and a linkage rope 122 is fixedly connected above the baffle 121. A linkage sleeve 542 is coaxially sleeved on the outside of the linkage rod 54, and the linkage sleeve 542 is vertically slidably connected to the linkage rod 54. A vertical rod 543 is fixedly connected below the first rotating motor 541, and the vertical rod 543 penetrates through and is relatively slidably connected to the position of the linkage sleeve 542.

[0045] Refer to Figure 4 、 Figure 5, a limiting block 544 is fixedly connected to the outer side wall of the linkage rod 54, and a limiting groove 5422 is formed in the inner side wall of the linkage sleeve 542. The limiting groove 5422 includes a spiral groove 54221. A ring groove 54222 is horizontally formed in the inner side wall of the linkage sleeve 542 relative to the bottom end of the spiral groove 54221. The spiral groove 54221 is relatively communicated with the ring groove 54222, and the spiral direction of the spiral groove 54221 is the same as the rotation direction of the first rotation motor 541.

[0046] The limiting block 544 is located inside the limiting groove 5422 and slides relatively. When the limiting block 544 is located at the top end of the spiral groove 54221, when the first rotation motor 541 drives the limiting block 544 to rotate, the limiting block 544 slides relatively inside the spiral groove 54221, pushing the linkage sleeve 542 to move upward. When the limiting block 544 extends from the inside of the spiral groove 54221 into the inside of the ring groove 54222, the limiting block 544 is located inside the ring groove 54222 and is connected by relative sliding, and thus the height of the linkage sleeve 542 does not change.

[0047] One end of the linkage rope 122 departing from the baffle 121 is fixedly connected to the linkage sleeve 542. A hinge sleeve 13 is fixedly connected to the side of the water storage tank 1 close to the linkage sleeve 542 relative to the linkage rope 122. The hinge sleeve 13 is sleeved on the outer side of the linkage rope 122 and is connected by relative sliding. When the linkage sleeve 542 moves upward driven by the limiting block 544, the linkage sleeve 542 drives the linkage rope 122 to move toward the side close to the linkage sleeve 542, thereby driving the baffle 121 to move upward, exposing the drain hole 12, and thus discharging the sewage located inside the purification part 3 into the sedimentation tank 56.

[0048] Refer to Figure 2 、 Figure 6 , a sedimentation tank 56 is arranged on one side of the water storage tank 1 at the drain hole 12. A filter mesh 561 is horizontally arranged inside the sedimentation tank 56, and a hydraulic cylinder 562 is vertically and fixedly connected to the top end of the sedimentation tank 56. The hydraulic rod of the hydraulic cylinder 562 is fixedly connected to the filter mesh 561.

[0049] By pushing the filter mesh 561 downward through the hydraulic cylinder 562, the impurities located inside the sedimentation tank 56 are filtered, and the impurities are pressed below the filter mesh 561. A sewage outlet 563 is horizontally formed at the lower end of the side wall of the sedimentation tank 56, and a screw conveyor 564 is horizontally arranged at the bottom of the sedimentation tank 56. The screw conveyor 564 is rotatably connected to the sedimentation tank 56. A second rotation motor 565 is fixedly connected to the position of the sedimentation tank 56 relative to the screw conveyor 564. The second rotation motor 565 can drive the screw conveyor 564 to rotate, and thus discharge the impurities located inside the sedimentation tank 56 from the position of the sewage outlet 563.

[0050] The side wall of the sedimentation tank 56 is also fixedly connected with a return water pipe 566, and the return water pipe 566 is relatively communicated with the purification part 3, so as to circulate the liquid after sedimentation and purification back to the purification part 3.

[0051] Refer to Figure 7 , Figure 8 , inside the water accumulation part 4, an air bag 41 is vertically arranged. The air bag 41 is of a hollow structure, and a jack 411 is formed by concave pressing at the position of the top end of the air bag 41 relative to the water guide pipe 32. The bottom end of the water guide pipe 32 can be inserted into the inside of the jack 411. A water outlet 14 is vertically opened at the bottom end of the water storage tank 1 relative to the lower side of the air bag 41. A sealing plate 141 is horizontally arranged at the position of the water storage tank 1 relative to the water outlet 14. The sealing plate 141 can completely block the water outlet 14, and a first spring 42 is fixedly connected to the bottom end of the water storage tank 1 relative to the position of the air bag 41. The top end of the first spring 42 is fixedly connected to the air bag 41. The bottom end of the air bag 41 is fixedly connected with a pull rope 412, and the bottom end of the pull rope 412 is fixedly connected with the sealing plate 141.

[0052] Refer to Figure 3 , Figure 8 , a spring hole 321 is horizontally opened on the side wall of the water guide pipe 32, and a ball 322 is slidably connected inside the spring hole 321. A second spring 323 is horizontally arranged on one side of the ball 322 close to the bottom of the spring hole 321. One end of the second spring 323 is fixedly connected to the ball 322, and the other end of the second spring 323 is fixedly connected to the water guide pipe 32. A limiting hole 413 is formed by concave pressing on the side wall of the air bag 41 relative to the position of the ball 322. When the water guide pipe 32 extends into the inside of the jack 411, the ball 322 extends into the inside of the limiting hole 413.

[0053] When the liquid inside the purification part 3 enters the inside of the water accumulation part 4 from the water guide pipe 32, as the amount of water increases, the air bag 41 is driven to move upward. The air bag 41 drives the pull rope 412 to move upward, and the pull rope 412 drives the sealing plate 141 to move upward. The sealing plate 141 exposes the water outlet 14, so that the liquid inside the water accumulation part 4 is discharged from the water outlet 14.

[0054] When the buoyancy force received by the air bag 41 and the fixing force generated by the ball 322 located in the limiting hole 413 are greater than the pulling force of the first spring 42 and the gravity of the air bag 41 itself, the liquid can be discharged from the position of the water outlet 14. And when the buoyancy force received by the air bag 41 and the fixing force generated by the ball 322 located in the limiting hole 413 are greater than the pulling force of the first spring 42 and the gravity of the air bag 41 itself, the ball 322 disengages from the inside of the limiting hole 413, and then the sealing plate 141 completely shields the water outlet 14.

[0055] The side wall of the water conduit 32 is horizontally provided with an overflow port 324, and an overflow plate 325 is vertically arranged outside the side wall of the water conduit 32. The overflow plate 325 can completely cover the overflow port 324, and a third spring 326 is horizontally arranged on the side of the overflow plate 325 close to the water conduit 32. An avoidance hole 327 is provided at the position of the water conduit 32 relative to the third spring 326, and the third spring 326 is located inside the avoidance hole 327 and fixedly connected to the water conduit 32. The third spring 326 is fixedly connected to the overflow plate 325.

[0056] When the water conduit 32 extends into the inside of the insertion hole 411, at this time, the airbag 41 completely seals the bottom end of the water conduit 32, and the liquid located inside the purification part 3 cannot enter the water accumulation part 4 from the water conduit 32. And when the liquid inside the water accumulation part 4 is gradually discharged, the airbag 41 descends, and the liquid located in the purification part 3 can enter the inside of the water accumulation part 4 from the water conduit 32. When there is more external liquid, and the water pressure inside the purification part 3 pushes the overflow plate 325 to move towards the side away from the water conduit 32, then the liquid inside the water conduit 32 can flow into the inside of the water accumulation part 4 from the position of the overflow port 324, which is convenient for the liquid inside the purification part 3 to be quickly discharged.

[0057] Refer to Figure 7 、 Figure 8 A detector 15 is arranged at the position of the bottom wall of the water storage tank 1 relative to the water outlet 14. The detector 15 can detect whether the sealing plate 141 is located at the position of the water outlet 14. When the time that the detector 15 detects that the sealing plate 141 is not located at the position of the water outlet 14 exceeds the predetermined time, it means that there is more liquid inside the water storage tank 1.

[0058] A support plate 43 is fixedly connected to the outside of the bottom wall of the airbag 41, and an adjustment hole 414 is concavely arranged below the airbag 41 relative to the insertion hole 411. The adjustment hole 414 is relatively communicated with the insertion hole 411, and an adjustment plate 415 is horizontally arranged inside the adjustment hole 414. The adjustment plate 415 is slidably connected to the airbag 41. A fourth spring 416 is vertically arranged below the adjustment plate 415. The top end of the fourth spring 416 is fixedly connected to the adjustment plate 415, and the bottom end of the fourth spring 416 is fixedly connected to the airbag 41.

[0059] A bidirectional lead screw 44 is horizontally arranged below the airbag 41. The bidirectional lead screw 44 is rotatably connected to the water storage tank 1, and a third rotating motor 441 is fixedly connected to one end of the water storage tank 1 relative to the bidirectional lead screw 44. The motor shaft of the third rotating motor 441 is coaxially and fixedly connected to the bidirectional lead screw 44. The third rotating motor 441 is in signal connection with the detector 15.

[0060] At both ends of the bidirectional lead screw 44, there are threadedly connected lifting blocks 442 respectively. The lifting blocks 442 are triangular structures, and the upper surfaces of the lifting blocks 442 are inclined. And the two lifting blocks 442 are gradually inclined upward along the side from relatively close to the side from relatively far away. When the time that the detector 15 detects that the sealing plate 141 is not at the position of the water outlet 14 exceeds the preset time, the detector 15 controls the third rotating motor 441 to rotate. Then, the third rotating motor 441 drives the bidirectional lead screw 44 to rotate, and the bidirectional lead screw 44 drives the two opposite lifting blocks 442 to move towards the relatively close direction. Then, the lifting blocks 442 push the support plate 43 to drive the airbag 41 to move upward, push the adjusting plate 415 downward. Then, through the upward movement of the airbag 41, drive the sealing plate 141 to move upward, increasing the gap between the sealing plate 141 and the bottom wall of the water outlet 14 of the water storage tank 1, facilitating the rapid outflow of the liquid.

[0061] A flexible net 142 is fixedly connected to the bottom ends of the sealing plate 141 and the water storage tank 1. Through the flexible net 142, it is possible to reduce the backflow of external sand and other impurities into the interior of the water storage tank 1 through the water outlet 14.

[0062] The implementation principle of a garden water circulation system in an embodiment of the present application is as follows: The liquid located outside enters the interior of the purification part 3 from the grating 11, and the liquid located inside the purification part 3 is filtered by the dynamic membrane 31, and then enters the interior of the water accumulation part 4 through the water guide pipe 32. As the liquid in the water accumulation part 4 gradually increases, it drives the airbag 41 to move upward, and the airbag 41 drives the sealing plate 141 to expose the water outlet 14 through the pull rope 412. The liquid in the water accumulation part 4 can be discharged from the position of the water outlet 14.

[0063] When there is more liquid outside, the third rotating motor 441 drives the bidirectional lead screw 44 to rotate. Then, the bidirectional lead screw 44 drives the two opposite lifting blocks 442 to move towards the relatively close direction. Then, the lifting blocks 442 push the support plate 43 to drive the airbag 41 to move upward, increasing the gap between the sealing plate 141 and the water outlet 14, facilitating the rapid discharge of the liquid in the water accumulation part 4.

[0064] The above are all the preferred embodiments of the present application. It does not limit the protection scope of the present application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
