[0002] Freshwater resources are one of the most important natural resources for human survival. For my country, although the total amount of freshwater resources ranks sixth in the world, the per capita water volume is only 1 / 4 of the world's per capita water volume. Therefore, freshwater resources are very precious natural resources in my country.

[0003] Collecting rainwater and utilizing it is a popular way to save water. A rainwater collection device is required for rainwater collection. Currently, some rainwater collection devices include drainage ditches and water storage tanks. During the rainwater collection process, the rainwater collected in the drainage ditch flows directly into the water storage tank through a pipe. However, the rainwater carries a lot of impurities as it flows into the drainage ditch, causing a lot of impurities to enter the water storage tank, which in turn causes the impurities to accumulate rapidly in the water storage tank. In order not to affect the normal use of the water storage tank, the impurities in the water storage tank need to be cleaned regularly. Summary of the Invention

[0037] Please refer to Figure 1-6 The present application provides a technical solution: a rainwater collecting device, comprising a drainage ditch (not shown in the figure), a water bucket 1, a filter cover 2, a support, a first pipeline 3, a water storage pool (not shown in the figure) and a second pipeline 4, the upper end of the water bucket 1 is open, the filter cover 2 is a conical cover body with a large end upward, that is, the filter cover 2 is a conical cover body with an open upper end, a plurality of filter holes 5 are arranged on the filter cover 2, the filter cover 2 can be turned over at its small end to form a conical cover body with an open downward, the diameter of the large end of the filter cover 2 is greater than the diameter of the water bucket 1, the support is used to support the filter cover 2 directly above the water bucket 1, the first pipeline 3 is used to guide the water in the drainage ditch into the filter cover 2, and the second pipeline 4 is used to guide the water in the water bucket 1 into the water storage pool.

[0038] When installing the rainwater collecting device described in the present application, the height position of the upper end of the filter cover 2 is lower than the bottom of the drainage ditch, and the water storage pool is lower than the bottom of the water bucket 1. One end of the first pipeline 3 is connected to the drainage ditch, and the other end is located directly above the middle of the filter cover 2, and the first pipeline 3 is in a downward inclined state from the end connected to the drainage ditch to the end located directly above the filter cover 2. One end of the second pipeline 4 is connected to the bottom of the water bucket 1, and the other end is connected to the water storage pool, and the second pipeline 4 is in a downward inclined state from the end connected to the water bucket 1 to the end connected to the water storage pool.

[0039] When the rainwater collecting device described in the present application is in the initial state, the large end of the filter cover 2 is upward, and the small end is downward, and the upper end of the filter cover 2 is open.

[0040] In rainy weather, rainwater can be collected by the rainwater collecting device described in the present application. When the rainwater collecting device described in the present application is used to collect rainwater, the rainwater will collect in the drainage ditch, the rainwater collected in the drainage ditch will flow into the filter cover 2 through the first pipeline 3, the water entering the filter cover 2 will fall downward through the filter holes 5 on the filter cover 2 and enter the water bucket 1, and the water entering the water bucket 1 will be guided into the water storage pool by the second pipeline 4. The rainwater collecting device described in the present application can collect rainwater in this way.

[0041] During the process of collecting rainwater, the large end of the filter cover 2 faces upward and the small end faces downward, so that the rainwater can be contained in the filter cover 2 and fall downward into the water bucket 1 through the filter holes 5 on the filter cover 2. The rainwater is not easy to spill out of the water bucket 1 from the edge of the filter cover 2, thereby improving the efficiency of collecting rainwater.

[0042] After the rainwater enters the filter cover 2 through the first pipe 3, the rainwater can be discharged through the filter holes 5 on the filter cover 2. Most of the impurities in the rainwater can be blocked by the filter cover 2 and retained in the filter cover 2, which can greatly reduce the impurities in the rainwater discharged into the water tank, reduce the accumulation rate of impurities in the water tank, and reduce the frequency of cleaning the water tank.

[0043] After a certain amount of impurities have accumulated within the filter cover 2, the small end of the filter cover 2 is tilted upward to above the large end of the filter cover 2, forming a tapered structure with the small end facing upward. At this point, the impurities within the filter cover 2 can move downward on the tapered surface of the filter cover 2 and fall from the edge of the large end of the filter cover 2. That is, after the filter cover 2 has formed a tapered structure with the small end facing upward, the impurities accumulated within the filter cover 2 can automatically fall from the edge of the large end of the filter cover 2, making it easier to clean the impurities within the filter cover 2. After the impurities within the filter cover 2 have been cleaned, clogged filter holes 5 can be reduced, allowing the rainwater collection device of the present invention to collect rainwater more smoothly.

[0044] After the filter cover 2 forms a conical cover body with the small end facing upward, the water discharged from the first pipe 3 can continuously flush the conical surface of the filter cover 2, making it easier for impurities on the conical surface of the filter cover 2 to fall off from the filter cover 2, so that the impurities in the filter cover 2 can be cleaned more cleanly.

[0045] Since the large end diameter of the filter cover 2 is larger than the diameter of the water bucket 1, the bracket is used to support the filter cover 2 directly above the water bucket 1, so that the large end edge of the filter cover 2 can be located outside the edge of the water bucket 1, so that impurities falling from the large end edge of the filter cover 2 are not easy to fall into the water bucket 1, which can reduce the impurities entering the water bucket 1 and further reduce the impurities entering the water storage tank.

[0046] After completing the cleaning of the impurities in the filter cover 2, the small end of the filter cover 2 can be turned down again to the bottom of the large end of the filter cover 2, so that the filter cover 2 is restored to a conical cover body with the large end facing upward. At this time, the filter cover 2 can continue to filter rainwater.

[0047] In this embodiment, the filter cover 2 can be made of a rubber material, which is soft and easily deformable. The small end of the filter cover 2 can be flipped up to above the large end of the filter cover 2.

[0048] In this embodiment, the projections of the plurality of filter holes 5 on a horizontal plane are all located within the projection of the opening at the upper end of the water bucket 1 on the horizontal plane. With this structure, after rainwater leaks out of the plurality of filter holes 5, the amount of rainwater leaking out of the water bucket 1 can be reduced, further improving the efficiency of rainwater collection.

[0049] In this embodiment, the bracket includes a support cover 6 and a support portion. The support cover 6 is a conical cover with the large end facing upward, that is, the support cover 6 is a conical cover with an upper end open. A plurality of leakage holes 7 are formed on the cover wall of the support cover 6. The support portion is used to support the support cover 6 directly above the bucket 1.

[0050] The filter cover 2 is located inside the support cover 6 and cooperates with the inner cavity of the support cover 6. The outer side surface of the filter cover 2 is supported on the inner side surface of the support cover 6, and the edge of the filter cover 2 is fixedly connected to the edge of the support cover 6.

[0051] After the first pipe 3 discharges the rainwater into the filter cover 2 , the rainwater contained in the filter cover 2 can sequentially pass through the filter holes 5 and the leakage holes 7 and fall downward into the water bucket 1 .

[0052] With this structure, the bracket can support the filter cover 2 directly above the water bucket 1. When the small end of the filter cover 2 needs to be flipped up to above the large end of the filter cover 2, it is only necessary to move the small end of the filter cover 2 upward relative to the support cover 6 to flip the small end of the filter cover 2 up to above the large end of the filter cover 2.

[0053] When the small end of the filter cover 2 is facing downward and filtering rainwater normally, the inner side surface of the support cover 6 can support the outer surface of the filter cover 2. The support cover 6 can form a more comprehensive support for the filter cover 2, which can reduce the deformation of the filter cover 2 under the impact of water discharged from the first pipe 3 and improve the service life of the filter cover 2.

[0054] In this embodiment, the bracket further includes a fixing portion for fixing the height of the small end of the filter cover 2;

[0055] The support portion includes a first frame and a first support assembly. The support cover 6 can be slidably connected to the first frame up and down. The first support assembly is arranged on the first frame. The first support assembly is used to support the support cover 6 on the first frame so that the support cover 6 is located directly above the bucket 1. The first support assembly can also release the support for the support cover 6.

[0056] When it is necessary to flip the small end of the filter cover 2 up to above the large end of the filter cover 2, release the support of the support cover 6 by the first support component and make the support cover 6 slide downward on the first frame, and the support cover 6 drives the large end of the filter cover 2 to slide downward. At this time, the fixing part fixes the height of the small end of the filter cover 2, and the small end of the filter cover 2 will not move downward with the support cover 6. At this time, the small end of the filter cover 2 can move upward relative to the support cover 6. After the support cover 6 slides downward for a certain distance, specifically, after the total distance the support cover 6 descends reaches twice the distance between the upper and lower ends of the filter cover 2, the small end of the filter cover 2 can be flipped up to above the large end of the filter cover 2 and form a conical cover body with the opening facing downward.

[0057] In this embodiment, the first supporting assembly includes a first base plate 8, a first slider (not shown in the figure), a first sliding rod 9, a first vertical plate 10, a second vertical plate 11 and a first coil spring 12. The first base plate 8 is fixed on the first frame, and the upper side surface of the first base plate 8 is recessed downward to form a first sliding groove 13 with an inner end closed. The first slider slides in the first sliding groove 13, and the first slider abuts against the inner end wall of the first sliding groove 13. The first sliding rod 9 is fixed on the first slider, and the inner end of the first sliding rod 9 is formed with a first inclined surface 14. The inner end of the first inclined surface 14 is inclined downward, and the inner end of the first inclined surface 14 is connected to the inner end surface of the first sliding rod 9. The outer end of the first inclined surface 14 is connected to the upper side surface of the first sliding rod 9. The first vertical plate 10 is fixed on the first base plate 8 and is located on the outer side of the first sliding rod 9. The second vertical plate 11 is fixed on the outer end of the first sliding rod 9. The first coil spring 12 is in a compressed state, and its outer end abuts the first vertical plate 10, and its inner end abuts the second vertical plate 11.

[0058] The support portion further includes a first connecting rod 15 , the inner end of the first connecting rod 15 is fixedly connected to the support cover 6 , and the lower side surface of the outer end is supported on the first inclined surface 14 .

[0059] In this solution, "inside" refers to the direction close to the middle of the support cover 6. In the subsequent description, "inside" has this meaning. "Outside" refers to the direction away from the middle of the support cover 6. In the subsequent description, "outside" has this meaning.

[0060] When the small end of the filter cover 2 is facing downward and filtering rainwater normally, the first inclined surface 14 supports the first connecting rod 15, and the first connecting rod 15 and the support cover 6 remain stationary. The first support assembly can thereby support the support cover 6 on the first frame.

[0061] A downward force is applied to the support cover 6, causing the support cover 6 and the first connecting rod 15 to move downward. During the downward movement of the first connecting rod 15, the first connecting rod 15 can push the first sliding rod 9 outward under the action of the first inclined surface 14. The first sliding block slides outward in the first sliding groove 13 along with the first sliding rod 9. The first coil spring 12 is further compressed, and the first connecting rod 15 slides downward relative to the first inclined surface 14. After the first connecting rod 15 moves downward a certain distance, the first connecting rod 15 disengages from the inner end of the first inclined surface 14. The first connecting rod 15 continues to move downward, and the first connecting rod 15 can disengage from the first sliding rod 9 downward. At this time, the support of the support cover 6 by the first support assembly can be released, and the support cover 6 and the first connecting rod 15 can continue to slide downward. It is relatively convenient to release the support of the support cover 6 by the first support assembly.

[0062] After the first connecting rod 15 moves to the bottom of the first sliding rod 9, the first coil spring 12 elastically resets and pushes the first sliding rod 9 inward, so that the first sliding rod 9 and the first slider move inward and reset.

[0063] In this embodiment, the bracket further includes a seat plate 16; a first guide hole is defined in the first connecting rod 15. The first guide hole is non-circular, specifically, square. The first frame includes a first guide rod 17 and a first vertical plate 18. The first guide rod 17 is fixed to the seat plate 16 and is disposed vertically. The first guide rod 17 slides within the first guide hole. The first vertical plate 18 is fixed to the seat plate 16, and the first bottom plate 8 is fixed to the first vertical plate 18. The bucket 1 is supported in the middle of the seat plate 16. With this structure, the first connecting rod 15 can be slidably connected to the first guide rod 17, and the support cover 6 can be slidably connected to the first frame, and the first bottom plate 8 can be fixed to the first frame.

[0064] In this embodiment, the rainwater collection device described in the present invention also includes a water tank 19 and a connecting pipe 20. The water tank 19 is fixed on the support cover 6 and is located below the support cover 6. The upper end of the water tank 19 is closed. One end of the connecting pipe 20 is fixedly connected to the upper part of the filter cover 2 and connected to the inner cavity of the filter cover 2, and the other end is fixedly connected to the water tank 19 and connected to the inner cavity of the water tank 19.

[0065] The upper end of the water tank 19 is closed, and the rainwater discharged from the filter holes 5 cannot fall into the water tank 19 .

[0066] When the small end of the filter cover 2 is facing downward and filtering rainwater normally, when there are fewer impurities in the filter cover 2, only a small part of the filter holes 5 on the filter cover 2 are blocked by impurities, and the water entering the filter cover 2 from the first pipe 3 can be quickly discharged from the multiple filter holes 5, and water will not accumulate in the filter cover 2.

[0067] As the amount of impurities in the filter housing 2 increases, most of the filter holes 5 of the filter housing 2 become clogged. At this point, the drainage rate of the unobstructed filter holes 5 on the filter housing 2 is slower than the drainage rate of the first pipe 3 into the filter housing 2. The water in the filter housing 2 gradually increases, and the water level in the filter housing 2 gradually rises. After the water level in the filter housing 2 rises to the upper end of the connecting pipe 20, the water in the filter housing 2 is discharged into the water tank 19 through the connecting pipe 20. As the water level in the water tank 19 gradually increases, the combined weight of the water tank 19 and its contents gradually increases. When the combined weight of the water tank 19 and its contents reaches a certain level, the support housing 6 and the first connecting rod 15 can move downward. The first connecting rod 15 can then push the first sliding rod 9 outward under the action of the first inclined surface 14. With this structure, the water tank 19 can exert a downward force on the support housing 6, causing the support housing 6 and the first connecting rod 15 to move downward.

[0068] When the amount of impurities in the filter cover 2 increases to a certain level, water can automatically flow into the water tank 19, automatically exerting a downward force on the support cover 6 and causing the support cover 6 and the first connecting rod 15 to move downward, automatically releasing the support of the support cover 6 by the first supporting assembly, and allowing the support cover 6 to automatically slide downward on the first frame, automatically causing the small end of the filter cover 2 to flip up to above the large end of the filter cover 2 and form a conical cover body with the opening facing downward, thereby automatically cleaning the impurities in the filter cover 2. This makes cleaning the impurities in the filter cover 2 more convenient.

[0069] In this embodiment, the water tank 19 is fixedly connected to the support cover 6 via a plurality of fixing rods 21 .

[0070] In this embodiment, the inner end of the first connecting rod 15 is fixedly connected to the water tank 19 , that is, the inner end of the first connecting rod 15 is indirectly fixedly connected to the support cover 6 through the water tank 19 .

[0071] In this embodiment, the water tank 19 is annular in shape, with its inner cavity coaxially disposed with the water tank 19. The diameter of the water tank 19 is smaller than the diameter of the opening at the upper end of the bucket 1. The water tank 19, the filter housing 2, and the bucket 1 are coaxially disposed. This structure prevents water that falls onto the upper side of the water tank 19 from easily draining out of the bucket 1, allowing rainwater discharged from the filter holes 5 to flow smoothly downward into the bucket 1.

[0072] In this embodiment, the fixing portion includes a second frame and a second support assembly. The small end of the filter cover 2 can be slidably connected to the second frame. The second support assembly is provided on the second frame. The second support assembly is used to support the small end of the filter cover 2 on the second frame. The second support assembly can also release the support for the small end of the filter cover 2.

[0073] The water tank 1 further includes a third support assembly, which is disposed on the first frame and is used to statically support the support cover 6 above the water bucket 1 after the filter cover 2 forms a conical cover with an opening facing downward. Specifically, the third support assembly is used to statically support the support cover 6 above the water bucket 1 after the total distance the support cover 6 descends reaches twice the distance between the upper and lower ends of the filter cover 2.

[0074] After the small end of the filter cover 2 is flipped up to above the large end of the filter cover 2 and a conical cover body with the opening facing downward is formed, the support of the small end of the filter cover 2 by the second support assembly is released and the small end of the filter cover 2 is allowed to slide downward on the second frame. The third support assembly statically supports the support cover 6 above the water bucket 1. At this time, the support cover 6 cannot move further downward. The small end of the filter cover 2 can continue to move downward for a certain distance under the action of its own gravity and the impact of water discharged from the first pipe 3. Then, the small end of the filter cover 2 can flip down to below the large end of the filter cover 2. The filter cover 2 can then be restored to the conical cover body with the large end facing upward. The outer side surface of the filter cover 2 can then be supported on the inner side surface of the support cover 6 again. At this time, the filter cover 2 can continue to filter rainwater.

[0075] When the support cover 6 is stationary supported on the third support assembly, the support cover 6 is specifically supported on the third support assembly through the water tank 19 and the first connecting rod 15 .

[0076] In this embodiment, the second supporting assembly includes a second bottom plate 22, a second slider (not shown in the figure), a second sliding rod 23, a third vertical plate 24, a fourth vertical plate 25 and a second coil spring 26. The second bottom plate 22 is fixed on the second frame. The upper side surface of the second bottom plate 22 is recessed downward to form a second sliding groove 27 with an inner end closed. The second slider slides in the second sliding groove 27. The second slider abuts against the inner end wall of the second sliding groove 27. The second sliding rod 23 is fixed on the second slider. A second inclined surface 28 is formed at the inner end of the second bottom plate 8, and the inner end of the second inclined surface 28 is inclined downward. The inner end of the second inclined surface 28 is in contact with the inner end surface of the second sliding rod 23, and the outer end of the second inclined surface 28 is in contact with the upper side surface of the second sliding rod 23. The third vertical plate 24 is fixed to the first bottom plate 8 and is located on the outer side of the second sliding rod 23. The fourth vertical plate 25 is fixed to the outer end of the second sliding rod 23. The second coil spring 26 is in a compressed state, with the outer end abutting against the third vertical plate 24 and the inner end abutting against the fourth vertical plate 25.

[0077] The support portion further includes a second connecting rod 29 , the inner end of the second connecting rod 29 being fixedly connected to the small end of the filter cover 2 , and the lower side surface of the outer end thereof being supported on the second inclined surface 28 .

[0078] The third supporting assembly specifically supports the supporting cover 6 statically above the water bucket 1 after the second connecting rod 29 is separated from the inner end of the second inclined surface 28 .

[0079] Before the small end of the filter cover 2 is flipped over to the top of the large end of the filter cover 2 and forms a conical cover body with the opening facing downward, the second inclined surface 28 supports the second connecting rod 29, and the second connecting rod 29 and the support cover 6 remain stationary. The second support assembly can thereby support the support cover 6 on the second frame.

[0080] After the small end of the filter cover 2 is flipped over to the top of the large end of the filter cover 2 and forms a conical cover body with the opening facing downward, as the support cover 6, the water tank 19 and the first connecting rod 15 continue to slide downward, the support cover 6, the water tank 19 and the first connecting rod 15 will provide a downward pulling force on the small end of the filter cover 2, and the small end of the filter cover 2 can pull the second connecting rod 29 downward. During the downward movement of the second connecting rod 29, the second connecting rod 29 can push the second sliding rod 23 outward under the action of the second inclined surface 28, and the second slider slides outward in the second slide groove 27 with the second sliding rod 23, the second coil spring 26 is further compressed, and the second connecting rod 29 slides downward relative to the second inclined surface 28. After the second connecting rod 29 moves downward a certain distance, the second connecting rod 29 disengages from the inner end of the second inclined surface 28, and the second connecting rod 29 continues to move downward, and the second connecting rod 29 can disengage from the second sliding rod 23 downward. At this time, the support of the support cover 6 by the second support assembly can be released, and the support cover 6 and the second connecting rod 29 can continue to slide downward.

[0081] After the second connecting rod 29 moves to the bottom of the second sliding rod 23, the second coil spring 26 elastically resets and pushes the second sliding rod 23 inward, so that the second sliding rod 23 and the second slider move inward and reset.

[0082] After the small end of the filter cover 2 is flipped over to the top of the large end of the filter cover 2 and forms a conical cover body with the opening facing downward, the support of the small end of the filter cover 2 by the second support assembly can be automatically released during the process of the support cover 6, the water tank 19 and the first connecting rod 15 continuing to slide downward.

[0083] After the second connecting rod 29 disengages from the inner end of the second inclined surface 28, the third support assembly statically supports the support cover 6 above the water bucket 1. Without the support of the second inclined surface, the small end of the filter cover 2 can continue to move downward a certain distance under its own weight and the impact of the water discharged from the first pipe 3, and flip down to below the large end of the filter cover 2. This can automatically cause the small end of the filter cover 2 to flip down below the large end of the filter cover 2, automatically restoring the filter cover 2 to its conical shape with the large end facing upward, and automatically causing the outer side of the filter cover 2 to be re-supported on the inner side of the support cover 6, thereby automatically allowing the filter cover 2 to continue filtering rainwater. This makes it more convenient for the filter cover 2 to continue filtering rainwater.

[0084] After the impurities in the filter cover 2 increase to a certain amount, the rainwater collection device described in the present invention can automatically clean the impurities in the filter cover 2 once, and can continue to filter the rainwater after completing the cleaning of the impurities in the filter cover, making the rainwater collection device described in the present invention more convenient to use.

[0085] In this embodiment, a second guide hole is provided on the second connecting rod 29. The second guide hole is non-circular; specifically, the second guide hole is square. The second frame includes a second guide rod 30 and a second vertical plate 31. The second guide rod 30 is fixed to the base plate 16. The second guide rod 30 is arranged vertically and slides into the second guide hole. The second vertical plate 31 is fixed to the base plate 16, and the second bottom plate 22 is fixed to the second vertical plate 31. With this structure, the second connecting rod 29 can be slidably connected to the second guide rod 30, and the small end of the filter cover 2 can be slidably connected to the second frame, and the second bottom plate 22 can be fixed to the second frame.

[0086] In this embodiment, the fixing portion further includes a circular ring 32, a transverse rod 33, and a longitudinal rod 34. The circular ring 32 is fixedly connected to the inner end of the second connecting rod 29. The circular ring 32 is arranged coaxially with the filter housing 2. The transverse rod 33 is fixedly disposed within the circular ring 32 and arranged radially along the circular ring 32. The upper end of the longitudinal rod 34 is fixedly connected to the middle portion of the transverse rod 33, and the lower end is fixedly connected to the small end of the filter housing 2. The nozzle of the end of the first pipe 3 located directly above the filter housing 2 faces the circular ring 32. With this structure, the inner end of the second connecting rod 29 can be fixedly connected to the small end of the filter housing 2, and water discharged from the first pipe 3 can be smoothly discharged to the middle portion of the filter housing 2.

[0087] In this embodiment, the rainwater collection device of the present invention further includes a drawstring 35. The upper end of the drawstring 35 is fixedly connected to the small end of the filter cover 2, and the lower end of the drawstring 35 is fixedly connected to the support cover 6. The drawstring 35 is in a straightened state when the filter cover 2 forms a tapered cover with the opening facing downward. Specifically, the drawstring 35 is in a straightened state when the total distance the support cover 6 descends reaches twice the distance between the upper and lower ends of the filter cover 2.

[0088] After the small end of the filter cover 2 is flipped over to the top of the large end of the filter cover 2 and forms a conical cover body with the opening facing downward, as the support cover 6, the water tank 19 and the first connecting rod 15 continue to slide downward, the downward pulling force provided by the support cover 6, the water tank 19 and the first connecting rod 15 to the small end of the filter cover 2 can act on the small end of the filter cover 2 through the pull rope 35, which can reduce the pulling force on the cover wall of the filter cover 2 and reduce the possibility of the cover wall of the filter cover 2 being damaged due to tension, thereby improving the service life of the rainwater collection device described in the present invention.

[0089] In this embodiment, the third supporting assembly includes a container 36, a mounting plate 37, a vertical rod 38, a bearing plate 39 and a third coil spring 40. The container 36 is fixed to the first frame. Specifically, the container 36 is fixed to the first vertical plate 18. The interior of the container 36 is hollow and the upper end is open. The container 36 contains a non-Newtonian fluid. The mounting plate 37 is fixed to the first frame and is located above the container 36. Specifically, the mounting plate 37 is fixed to the first vertical plate 18. A through hole is provided on the mounting plate 37. The vertical rod 38 slidably fits into the through hole. The lower end of the vertical rod 38 is located in the container 36 and abuts the upper side of the non-Newtonian fluid. The bearing plate 39 is fixed to the upper end of the vertical rod 38 and is located directly below the outer end of the first connecting rod 15. The upper end of the third coil spring 40 abuts the bearing plate 39, and the lower end abuts the mounting plate 37.

[0090] When the filter cover 2 forms a conical cover body with the opening facing downward, the first connecting rod 15 contacts the supporting plate 39 downward.

[0091] Non-Newtonian fluids are made of starch and water in a mass ratio of 1:2 to 2.5. Non-Newtonian fluids have the characteristic of increasing viscosity and becoming unable to flow when impacted. When an external force is slowly applied to the non-Newtonian fluid, the non-Newtonian fluid has the fluidity of a liquid.

[0092] Before the filter cover 2 forms a conical cover body with the opening facing downward, the support cover 6, the water tank 19 and the first connecting rod 15 slide downward and accelerate under the action of gravity. When the filter cover 2 forms a conical cover body with the opening facing downward, the first connecting rod 15 contacts and impacts the supporting plate 39 downward at a relatively fast speed, forming a rapid and downward impact force on the supporting plate 39 and the vertical rod 38. The lower end of the vertical rod 38 suddenly squeezes the non-Newtonian fluid. At this time, the non-Newtonian fluid shows a sudden increase in viscosity and has the characteristics of solid rigidity and cannot flow. At this time, the vertical rod 38 and the supporting plate 39 slow down to a state close to a stop, and the first connecting rod 15, the water tank 19 and the support cover 6 slow down to a state close to a stop.

[0093] Then, under the action of the gravity of the first connecting rod 15, the water tank 19 and the support cover 6, the first connecting rod 15, the water tank 19, the support cover 6, the movable plate and the vertical rod 38 will slowly move down and compress the spring. At this time, the vertical rod 38 slowly squeezes the non-Newtonian fluid instead of producing a rapid extrusion impact on the non-Newtonian fluid. At this time, the non-Newtonian fluid has the same fluidity as a conventional liquid, and the vertical rod 38 can slowly sink into the non-Newtonian fluid. After the first connecting rod 15, the water tank 19, the support cover 6, the movable plate and the vertical rod 38 slowly move down a certain distance, that is, after the coil spring is compressed a certain distance, the elastic force of the coil spring and the pressure of the support plate 39 on the coil spring reach equilibrium, and the first connecting rod 15, the water tank 19, the support cover 6, the movable plate and the vertical rod 38 stop moving down. At this time, the third support assembly can statically support the support cover 6 so that the support cover 6 cannot continue to move downward.

[0094] After the small end of the filter cover 2 is flipped over to the top of the large end of the filter cover 2 and a conical cover body with an opening facing downward is formed, as the support cover 6, water tank 19 and first connecting rod 15 continue to slide downward, the support cover 6, water tank 19 and first connecting rod 15 move slowly downward, and the small end of the filter cover 2 and the second connecting rod 29 can be slowly pulled downward, so that the second connecting rod 29 can more slowly disengage from the second inclined surface 28, so that the second connecting rod 29 can more slowly disengage from the second sliding rod 23 downward, and thus the support of the support cover 6 by the second support assembly can be more slowly released, so that the filter cover 2 can be maintained in the state of a conical cover body with an opening facing downward for a longer time, so that the rainwater discharged from the first pipe 3 can wash away the impurities on the conical surface of the filter cover 2 more cleanly, and thus the impurities on the filter cover 2 can be cleaned more cleanly.

[0095] In this embodiment, a third inclined surface 41 is formed at the inner end of the first sliding rod 9. The inner end of the third inclined surface 41 is inclined upward and is in contact with the inner end surface of the first sliding rod 9. The outer end of the second inclined surface 28 is in contact with the lower side surface of the second sliding rod 23. The third inclined surface 41 and the first inclined surface 14 are symmetrically arranged on the upper and lower sides of the center line of the first sliding rod 9.

[0096] A fourth inclined surface 42 is formed at the inner end of the second sliding rod 23, and the inner end of the fourth inclined surface 42 is inclined upward. The inner end of the fourth inclined surface 42 is connected to the inner end surface of the second sliding rod 23, and the outer end of the fourth inclined surface 42 is connected to the lower side surface of the second sliding rod 23; the fourth inclined surface 42 and the second inclined surface 28 are symmetrically arranged on the upper and lower sides of the center line of the second sliding rod 23.

[0097] After the rain stops, the staff checks the rainwater collection device described in the present invention. If it is found that the first connecting rod 15 has moved down to support on the supporting plate 39, and the second connecting rod 29 has moved down to below the second sliding rod 23, it is necessary to move the second connecting rod 29 back up to support on the second inclined surface 28, and move the first connecting rod 15 back up to support on the first inclined surface 14.

[0098] When the second connecting rod 29 is moved upward again until it is supported on the second inclined surface 28, the second connecting rod 29 is moved upward so that the upper side surface of the outer end of the second connecting rod 29 abuts the fourth inclined surface 42. The second connecting rod 29 is then further moved upward. Under the action of the fourth inclined surface 42, the second connecting rod 29 can push the second sliding rod 23 outward. The second slider slides outward in the second sliding groove 27 along with the second sliding rod 23. The second coil spring 26 is further compressed, and the second connecting rod 29 slides upward relative to the fourth inclined surface 42. After the second connecting rod 29 moves upward a certain distance, the second connecting rod 29 disengages from the inner end of the fourth inclined surface 42. The second connecting rod 29 is then further moved upward, and the second connecting rod 29 can be upwardly disengaged from the second sliding rod 23.

[0099] After the second connecting rod 29 moves to above the second sliding rod 23, the second coil spring 26 elastically returns to its original position and pushes the second sliding rod 23 inward, causing the second sliding rod 23 and the second slider to move inward and return to their original position. The second connecting rod 29 is then moved downward so that it can be supported on the second inclined surface 28 again.

[0100] When the first connecting rod 15 is moved upward again until it is supported on the first inclined surface 14, the first connecting rod 15 is moved upward so that the upper side surface of the outer end of the first connecting rod 15 abuts against the third inclined surface 41. Then, the first connecting rod 15 is further moved upward. Under the action of the third inclined surface 41, the first connecting rod 15 is able to push the first sliding rod 9 outward. The first sliding block slides outward in the first sliding groove 13 along with the first sliding rod 9. The first coil spring 12 is further compressed, and the first connecting rod 15 slides upward relative to the third inclined surface 41. After the first connecting rod 15 moves upward a certain distance, the first connecting rod 15 disengages from the inner end of the third inclined surface 41. Then, the first connecting rod 15 is further moved upward, and the first connecting rod 15 is able to disengage from the first sliding rod 9 upward.

[0101] After the first connecting rod 15 moves to above the first sliding rod 9, the first coil spring 12 elastically returns to its original position and pushes the first sliding rod 9 inward, causing the first sliding rod 9 and the first slider to move inward and return to their original position. The first connecting rod 15 is then moved downward so that it can be supported on the first inclined surface 14 again.

[0102] In this embodiment, a drainage hole 43 is provided on the lower end wall of the water tank 19, and the aperture of the drainage hole 43 is smaller than the inner diameter of the connecting pipe 20, so that the drainage speed of the drainage hole 43 is lower than the speed at which the connecting pipe 20 guides water into the water tank 19.

[0103] During the process of the water in the connecting cover entering the water tank 19 through the connecting pipe 20, the speed at which the connecting pipe 20 supplies water to the water tank 19 is greater than the speed at which the drain hole 43 discharges the water in the water tank 19, so that the amount of water in the water tank 19 gradually increases.

[0104] After the impurities on the filter cover 2 are cleaned, the filter cover 2 continues to filter the rainwater. Before most of the filter holes 5 of the filter cover 2 are blocked, the rainwater in the filter cover 2 can fall into the water bucket 1 through the leakage hole 7, and the rainwater in the filter cover 2 will not enter the water tank 19 through the connecting pipe 20. The drainage hole 43 can continuously discharge the water in the water tank 19 and can drain the water in the water tank 19 to a state close to being drained, making it easier for the staff to move up the first connecting rod 15, the water tank 19 and the support cover 6.

[0105] In this embodiment, air holes 44 are provided on the sidewall of the water tank 19, connecting the inner cavity of the water tank 19 with the outer surface of the water tank 19. The air holes 44 connect the inner cavity of the water tank 19 to the outside environment, preventing the air pressure in the water tank 19 from increasing or decreasing. This allows water to flow smoothly through the connecting pipe 20 into the inner cavity of the water tank 19 and to be discharged smoothly from the drain hole 43.

[0106] In this embodiment, a guide plate 45 is further included. The guide plate 45 is in a circular ring shape and is arranged in a ring around the upper part of the support cover 6. The edge of the inner hole of the guide plate 45 is fixedly connected to the outer side surface of the support cover 6. The upper side surface of the guide plate 45 is a conical surface that gradually tilts downward from the middle to the edge. The outer edge of the guide plate 45 is located outside the edge of the support cover 6.

[0107] The impurities in the filter housing 2 move downward on the conical surface of the filter housing 2 and fall from the large end edge of the filter housing 2. The impurities can then fall onto the upper side of the guide plate 45 and fall at the lower end edge of the upper side of the guide plate 45. The guide plate 45 can guide the impurities to a position farther away from the water bucket 1, thereby reducing the possibility of the impurities falling into the water bucket 1.

[0108] The present invention also provides another technical solution: a spray maintenance equipment for construction, comprising the above-mentioned rainwater collection device, a first water pipe (not shown in the figure), a water pump (not shown in the figure), a second water pipe (not shown in the figure) and a nozzle (not shown in the figure), one end of the first water pipe is located in the water storage tank, the water inlet of the water pump is fixedly connected to the other end of the first water pipe, one end of the second water pipe is fixedly connected to the water outlet of the water pump, and the nozzle is fixedly connected to the other end of the second water pipe.

[0109] During construction, when the concrete structure needs to be watered and maintained, the water pump is started. Under the pumping action of the water pump, the water in the water tank can enter the sprinkler head through the first water pipe, the water pump, and the second water pipe in sequence, and then be sprayed from the sprinkler head onto the concrete to achieve spray maintenance of the concrete.

[0110] By collecting rainwater for concrete spray curing, we can make rational use of rainwater, reduce the use of tap water, and save construction costs.

[0111] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
