Description

Technical Field

[0001] The present application relates to the field of municipal engineering technology, and in particular to a rainwater collection device for municipal gardens. Background Art

[0002] Rainwater collection equipment for municipal gardens is a device used to collect and utilize rainwater to make full use of natural resources and save water resources.

[0003] Rainwater collection equipment collects rainwater from rainwater collection surfaces (hardened ground in gardens, green spaces, etc.); and filters, precipitates, and purifies the rainwater; the treated rainwater is stored in water storage facilities (such as water tanks, water towers, etc.); the stored rainwater can be used through the water distribution system to irrigate flowers, trees, replenish landscape water, flush toilets, etc.

[0004] Since rainwater in municipal gardens flows through a large area of ​​green space, and rainwater filtering devices such as rainwater grates can only filter impurities such as leaves with a larger area, the rainwater collected in the rainwater pipes contains other solid impurities such as leaves with a smaller area, mud and sand.

[0005] In the prior art, a filter is often installed in the rainwater collection equipment to filter out solid impurities in the rainwater. However, when the sand content of the municipal garden soil is high and the rainwater washes the ground to a large extent, the rainwater will contain more solid impurities, so that the small particles of solid impurities block the holes of the filter, thus affecting the collection of rainwater. Summary of the invention

[0006] In order to reduce the occurrence of impurities in rainwater clogging rainwater collection equipment and improve the ability of rainwater collection equipment to continuously collect rainwater, the present application provides a rainwater collection equipment for municipal gardens.

[0007] The present application provides a rainwater collection device for municipal gardens, which adopts the following technical solution: A rainwater collection device for municipal gardens, rainwater from municipal gardens is collected through a rainwater surface and flows into a primary rainwater pipe; The rainwater collection device comprises a filter pipe, a water storage tank and a filter mechanism, wherein the filter mechanism is fixedly arranged on the inner wall of the water storage tank, the filter pipe is connected with the primary rainwater pipe, and the filter pipe transports rainwater to the filter mechanism; The filtering mechanism comprises a filtering assembly, a first driving assembly and a drainage cylinder; the filtering assembly is fixed on the inner side wall of the water storage tank, the filtering assembly comprises a telescopic cylinder and a movable plate, two telescopic cylinders are provided, the two telescopic cylinders are arranged on both sides of the movable plate, the filtering pipe extends into the telescopic cylinder, the diameter of the telescopic cylinder increases along the direction away from the movable plate, a plurality of water-permeable holes are provided on the side wall of the telescopic cylinder, the telescopic cylinder is provided with a first drop opening, the first drop opening is arranged on the side of the telescopic cylinder away from the movable plate, and the movable plate is used to drive the telescopic cylinder to compress or extend; the first driving assembly is fixed on the water storage tank, the first driving assembly is used to drive the movable plate to move horizontally, when the movable plate moves horizontally, one telescopic cylinder is compressed and the other telescopic cylinder is extended; the drainage cylinder is fixed in the water storage tank, the drainage cylinder is arranged directly below the first drop opening, the drainage cylinder is used to receive rainwater falling from the first drop opening, and the drainage cylinder is externally connected to a secondary rainwater pipe.

[0008] By adopting the above technical solution, rainwater is transported to the extended telescopic cylinder through the primary rainwater pipe and the filter pipe, and the rainwater will pass through the water-permeable holes on the telescopic cylinder, and fall into the water storage tank for storage, while solids such as leaves and mud in the rainwater stay inside the telescopic cylinder. When the first driving component drives the telescopic cylinder to move toward the first drop-out port, the length of the side wall of the telescopic cylinder decreases gradually to push the solid impurities on the side wall of the cylinder toward the first drop-out port. After the rainwater flows out of the filter pipe, it will collide with the movable plate, and the rainwater after the collision will move along the side wall of the cylinder toward the first drop-out port, thereby pushing the solid impurities on the side wall of the cylinder into the first drop-out port, reducing the occurrence of solid impurities blocking the water-permeable holes.

[0009] During the process of filtering and collecting rainwater, the filtering mechanism drives one telescopic cylinder to be compressed and the other telescopic cylinder to be stretched through the reciprocating motion of the moving plate; the stretched telescopic cylinder has a longer cylinder side wall, and the stretched telescopic cylinder plays a role in filtering rainwater; while the other telescopic cylinder is compressed, so that the compressed telescopic cylinder will automatically clean the solid impurities remaining inside.

[0010] In the rainwater collection device of the present technical solution, while filtering and collecting rainwater, the rainwater collection device will self-clean the telescopic cylinder that performs a filtering function, thereby reducing the situation where solid impurities clog the water-permeable holes on the telescopic cylinder, thereby ensuring the continuous operation of the rainwater collection device and increasing the amount of rainwater collected by the rainwater collection device.

[0011] Optionally, the telescopic cylinder includes a single-section ring, a limit plate, a first limit ring and a second limit ring; there are several single-section rings, and the diameter of the single-section ring increases along the direction away from the movable plate, and several single-section rings are slidingly spliced; the first limit ring is fixedly arranged on the outer side of the single-section ring, and the first limit ring is arranged on the side of the single-section ring away from the movable plate, the second limit ring is fixedly arranged on the inner side of the single-section ring, and the first limit ring is arranged on the side of the single-section ring close to the movable plate, and the first limit ring is used to abut against the second limit ring; the limit plate is arranged on the side of the telescopic cylinder away from the movable plate, and the limit plate is fixedly connected to the single-section ring, and the limit ring is used to abut against several single-section rings.

[0012] By adopting the above technical solution, adjacent single-section rings are slidably spliced, and the adjacent single-section rings are sealed and connected through the first limiting ring and the second limiting ring; thereby facilitating the compression deformation and tension deformation of the telescopic cylinder.

[0013] Optionally, a fracture line is provided on the single-section ring along the generatrix direction of the single-section ring, and the fracture lines of several of the single-section rings are located on the same plane; a notch is provided on the single-section ring, and the notch is arranged on the side of the single-section ring away from the movable plate, and the notch is connected with the fracture line; a pushing convex strip is provided on the side of the limiting plate close to the movable plate, and the pushing convex strip and the fracture line are located on the same plane; when the single-section ring moves toward the limiting plate, the pushing convex strip is inserted into the notch, and the pushing convex strip forces the single-section ring to open a second drop opening along the fracture line, and the drain tube is used to receive rainwater falling from the second drop opening; the first limiting ring and the second limiting ring are made of flexible material, and the first limiting ring and the second limiting ring are compressed and deformed when the single-section ring expands outward.

[0014] By adopting the above technical solution, when the telescopic cylinder is in the state of filtering solid impurities, the side wall of the telescopic cylinder is a continuous surface to ensure the filtering function of the telescopic cylinder. When the telescopic cylinder is in the self-cleaning state, the push convex strip passes through the notch of the telescopic cylinder, and can force the side wall of the cylinder to open a second drop opening along the fracture line. Therefore, when rainwater is reflected to the telescopic cylinder by the moving plate, the rainwater will carry solid impurities and fall from the second drop opening into the drainage cylinder, so as to improve the self-cleaning effect of the telescopic cylinder.

[0015] Optionally, the telescopic cylinder also includes an elastic sealing strip, wherein two elastic sealing strips are provided, the elastic sealing strips are arranged on both sides of the fracture line, and the elastic sealing strip is fixedly connected to the single-section ring; when the telescopic cylinder is in a working state of filtering rainwater, the two elastic sealing strips are tightly abutted.

[0016] By adopting the above technical solution, the two elastic sealing strips are tightly abutted to ensure the sealing of the telescopic cylinder at the fracture line.

[0017] Optionally, the filtering assembly also includes a reflective plate, which is arranged in the telescopic cylinder. There are two reflective plates, which are fixed on both sides of the movable plate. The reflective plate is arranged opposite to the first-level rainwater pipe, and a plurality of irregular protrusions are provided on the surface of the reflective plate. The rainwater in the first-level rainwater pipe is jetted onto the reflective plate, and the rainwater is reflected onto the single-section ring by the reflective plate.

[0018] By adopting the above technical solution, when rainwater flows out of the filter pipe and hits the irregular protrusions on the reflective plate, the reflected water flow will be ejected in different directions, so that the water flow can hit most areas on the side wall of the cylinder to clean out the mud and sand in the water permeable holes, thereby further improving the self-cleaning effect of the filter mechanism.

[0019] Optionally, the rainwater collection device also includes a cleaning mechanism, which includes a cleaning cover, a connecting seat, a water supply steel pipe and a water supply hose; when the telescopic cylinder is compressed to one of the single-section rings, the cleaning cover is arranged on the outer periphery of the telescopic cylinder, and the cleaning cover is abutted against the movable plate; the connecting seat is arranged on the side of the cleaning cover close to the telescopic cylinder, the water supply steel pipe is connected to the connecting seat, one end of the water supply hose is connected to the water supply steel pipe, and the other end of the water supply hose is externally connected to a water supply pipe; after the water is output through the water supply steel pipe, the rainwater is jetted to the cleaning cover and the telescopic cylinder.

[0020] By adopting the above technical solution, when the telescopic cylinder is compressed to a single-section ring length and is in a self-cleaning state, the water will directly hit the telescopic cylinder after being ejected through the conveying steel pipe, or hit the telescopic cylinder after being reflected by the cleaning cover. The water with a large flow rate can hit the telescopic cylinder from the outside of the telescopic cylinder and the solid impurities in the water permeable hole, thereby causing the telescopic cylinder to vibrate to shake off the solid impurities on the side wall of the cylinder, thereby facilitating the solid impurities on the side wall of the cylinder to fall from the first drop port.

[0021] Optionally, an annular groove is provided on the reflecting plate, and when the telescopic cylinder is compressed to a single-section ring, the filter pipe is inserted into the annular groove, and the reflecting plate blocks the filter pipe; the water supply hose is connected to the filter pipe, and the diameter of the filter pipe is smaller than the diameter of the water hose.

[0022] By adopting the above technical solution, when the movable plate moves toward the first drop opening, the filter pipe is inserted into the annular groove, so that the reflector blocks the filter pipe; thus, there is no water flow inside the filter pipe. When the cleaning mechanism ejects water flow from the outer periphery of the telescopic cylinder, the water flow collides with the outer wall of the telescopic cylinder, which increases the degree of vibration of the telescopic cylinder, so that solid impurities on the telescopic cylinder fall off, further improving the self-cleaning effect of the telescopic cylinder.

[0023] At the same time, the reflective plate blocks the filter pipe, so that the water in the middle of the filter pipe is ejected through the water hose and the delivery steel pipe, thereby utilizing the rainwater jet expansion pipe in the filter pipe to reduce the installation of external water supply equipment and save water resources.

[0024] Optionally, the cleaning mechanism further comprises a spring member, one end of the elastic member is fixedly connected to the water delivery steel pipe, the other end of the elastic member is fixedly connected to the cleaning cover, and the water delivery steel pipe is spherically hinged to the connecting seat.

[0025] By adopting the above technical solution, the delivery steel pipe is spherically hinged with the connecting seat, so that when water jets out from the delivery steel pipe, the delivery steel pipe will rotate with the connecting seat, so that the delivery steel pipe can jet water in different directions, thereby improving the cleaning effect of the cleaning mechanism on the telescopic cylinder.

[0026] Optionally, the filtering mechanism further comprises a second driving assembly, which is used to drive the telescopic cylinder to rotate; a spherical protrusion is provided on the outer periphery of the telescopic cylinder, and the spherical protrusion is used to force the water delivery steel pipe to rotate around the hinge point of the water delivery steel pipe.

[0027] By adopting the above technical solution, when the telescopic cylinder drives the spherical protrusion to rotate, the spherical protrusion forces the water delivery steel pipe to rotate around the connecting seat, so that the water delivery steel pipe can spray water in different directions, thereby improving the cleaning effect of the cleaning mechanism on the telescopic cylinder.

[0028] Optionally, the filtering mechanism further includes a second driving assembly, and the second driving assembly is used to drive the telescopic cylinder to rotate.

[0029] By adopting the above technical solution, the second drive assembly drives the telescopic cylinder to rotate, and the rotating telescopic cylinder forces the solid impurities in the rainwater to move toward the first drop-out port, thereby improving the self-cleaning effect of the filtering mechanism. When the telescopic cylinder is in the self-cleaning state, the second drive assembly drives the telescopic cylinder to rotate, so that the water jetted by the cleaning mechanism can cover more surface area of ​​the telescopic cylinder, thereby improving the cleaning effect of the cleaning mechanism on the telescopic cylinder.

[0030] In summary, the present application includes at least one of the following beneficial technical effects: 1. While the rainwater collection device is filtering and collecting rainwater, it will self-clean the telescopic cylinder that plays a filtering role, thereby reducing the situation where solid impurities block the water-permeable holes on the telescopic cylinder, so as to ensure the continuous operation of the rainwater collection device and increase the amount of rainwater collected by the rainwater collection device; 2. When the telescopic cylinder is in the state of filtering solid impurities, the side wall of the telescopic cylinder is a continuous surface to ensure the filtering function of the telescopic cylinder. When the telescopic cylinder is in the self-cleaning state, the push convex strip passes through the notch of the telescopic cylinder, which can force the side wall of the cylinder to open a second drop opening along the fracture line. Therefore, when rainwater is reflected to the telescopic cylinder by the moving plate, the rainwater will carry solid impurities and fall from the second drop opening into the drainage cylinder, so as to improve the self-cleaning effect of the telescopic cylinder; 3. When the telescopic cylinder is compressed to a single-section ring length and is in a self-cleaning state, the water will directly hit the telescopic cylinder after being ejected through the conveying steel pipe, or hit the telescopic cylinder after being reflected by the cleaning cover. The water with a large flow rate may hit the telescopic cylinder from the outside of the telescopic cylinder and hit the solid impurities in the water permeable hole, thereby causing the telescopic cylinder to vibrate to shake off the solid impurities on the side wall of the cylinder, thereby facilitating the solid impurities on the side wall of the cylinder to fall from the first drop port.

Rainwater from municipal gardens is collected through rainwater surfaces (hardened ground, green space, etc. in the gardens) and flows into a primary rainwater pipe 91. Since rainwater from municipal gardens flows through a large area of ​​green space, rainwater filtering devices such as rainwater grates can only filter impurities such as leaves with a larger area; the rainwater collected by the primary rainwater pipe 91 contains other small solid impurities such as leaves with a smaller area, mud and sand.

In the vertical upward direction, the step groove includes a first step groove 21 and a second step groove 22. The cross-sectional area of ​​the first step groove 21 is smaller than the cross-sectional area of ​​the second step groove 22. A mounting seat for the filter mechanism 3 is provided on the bottom wall of the second step groove 22. The first step groove 21 is used to store filtered rainwater. The water storage tank 2 can also be connected to a pool body or a water storage tank with a larger storage space to collect more rainwater.

[0055] Reference Figure 1 and Figure 2 The filter mechanism 3 is fixed on the inner side wall of the water storage tank 2, and the filter mechanism 3 is arranged on the mounting seat of the bottom wall of the second step groove 22. The filter pipe 1 is connected with the primary rainwater pipe 91, and a through hole for the filter pipe 1 to pass through is arranged on the side wall of the water storage tank 2. The filter pipe 1 transports rainwater collected by the primary rainwater pipe 91 to the filter mechanism 3.

[0056] Reference Figure 2 and Figure 3 The filtering mechanism 3 includes a filtering component 4, a first driving component 5 and a drainage cylinder 6.

[0057] Reference Figure 2 and Figure 3The filter assembly 4 is fixed on the inner wall of the water tank 2, and the filter assembly 4 includes a telescopic cylinder 41 and a movable plate 42. Two telescopic cylinders 41 are provided, and the two telescopic cylinders 41 are fixed on both sides of the movable plate 42, and the central axis of the telescopic cylinder 41 is arranged horizontally. The movable plate 42 is used to compress or stretch the telescopic cylinder 41 to change the length of the telescopic cylinder 41. The filter pipe 1 is passed through the telescopic cylinder 41, and the filter pipe 1 extends into the inner chamber of the telescopic cylinder 41.

[0058] Reference Figure 3 and Figure 4 , the first driving assembly 5 is fixed on the water tank 2, the driving direction of the first driving assembly 5 is horizontal, and the driving direction of the first driving assembly 5 is consistent with the central axis of the telescopic cylinder 41, and the first driving assembly 5 is used to drive the movable plate 42 to move horizontally. When the movable plate 42 moves horizontally, one telescopic cylinder 41 is compressed and the other telescopic cylinder 41 is extended. In this embodiment, the telescopic cylinder 41 on the left side of the movable plate 42 is in a compressed state, and the telescopic cylinder 41 on the right side of the movable plate 42 is in a stretched state. When the movable plate 42 moves to the right, the telescopic cylinder 41 on the left side of the movable plate 42 stretches toward the middle area of ​​the water tank 2, and the length of the telescopic cylinder 41 on the left side of the movable plate 42 becomes longer; while the telescopic cylinder 41 on the right side of the movable plate 42 moves toward the side wall of the water tank 2, and the length of the telescopic cylinder 41 on the right side of the movable plate 42 becomes shorter.

[0059] The first driving assembly 5 can be a linear reciprocating driving member such as a cylinder, an electric push rod, or an oil cylinder. In this embodiment, the first driving assembly 5 is a cylinder. The number of the first driving assembly 5 can be one, two, or three. In this embodiment, one first driving assembly 5 is provided. In other embodiments, two first driving assemblies 5 can be symmetrically provided along the moving plate 42.

[0060] Reference Figure 3 and Figure 4 The telescopic cylinder 41 includes a single-section ring 411 , a limiting plate 412 , a first limiting ring 413 and a second limiting ring 414 .

[0061] Reference Figure 3 and Figure 4 , a plurality of single-section rings 411 are provided, and the diameter of the single-section rings 411 increases gradually along the direction away from the moving plate 42, and a plurality of single-section rings 411 are slidably spliced; thereby, the compression and extension of the telescopic cylinder 41 are realized through the horizontal movement of the moving plate 42. A plurality of water-permeable holes 4111 are provided on the side wall of the single-section ring 411 to filter solid impurities in rainwater. It is worth noting that in order to reflect the water-permeable holes 4111 in the single-section ring 411; the drawings of the specification of this application adopt an exaggerated drawing method to reflect the water-permeable holes 4111 in the single-section ring 411.

[0062] Reference Figure 4The limit plate 412 is arranged on the side of the telescopic cylinder 41 away from the moving plate 42, and the limit plate 412 is fixedly connected to the single-section ring 411, and the limit ring is used to abut against a plurality of single-section rings 411. Therefore, when the moving plate 42 and the limit plate 412 are close to each other, the moving plate 42 and the limit plate 412 will squeeze the telescopic cylinder 41, so that the plurality of single-section rings 411 are stacked and the telescopic cylinder 41 is compressed.

[0063] Reference Figure 3 and Figure 4 In this embodiment, the single-section ring 411 fixed to the limiting plate 412 is provided with a first drop opening 4112, and the first drop opening 4112 is used for rainwater containing solid impurities to drop. The drainage cylinder 6 is fixedly arranged directly below the first drop opening 4112, and the drainage cylinder 6 is used to receive rainwater containing solid impurities. The drainage cylinder 6 is externally connected to the secondary rainwater pipe 92 to discharge rainwater containing more solid impurities out of the rainwater collection device.

[0064] Reference Figure 5 and Figure 6 The telescopic cylinder 41 is bent away from the moving plate 42 to form a fixed groove 416, and a support member 23 is fixed on the inner wall of the water tank 2, and the support member 23 is inserted into the fixed groove 416; thereby, the filter assembly 4 is fixed horizontally on the inner wall of the water tank 2, and the displacement of the telescopic cylinder 41 away from the moving plate 42 is limited. The support member 23 can be a metal block, a roller or other component with a supporting function. In this embodiment, the support member 23 is a metal block, and the metal block is fixed on the side wall of the water tank 2. The connection method between the telescopic cylinder 41 and the moving plate 42 can be welding fixation or rotation connection; this embodiment does not limit the specific connection method between the telescopic cylinder 41 and the moving plate 42.

[0065] Reference Figure 3 and Figure 4 The first limiting ring 413 and the second limiting ring 414 are arranged between adjacent single-section rings 411 to limit the sliding connection between adjacent single-section rings 411 .

[0066] Reference Figure 7 In this embodiment, for the convenience of description, among the adjacent single-section rings 411, the single-section ring 411 with a smaller diameter is named as the inner ring single-section ring 4116, and the single-section ring 411 with a larger diameter is named as the outer ring single-section ring 4117. The first limiting ring 413 is fixedly arranged on the side of the outer ring single-section ring 4117 away from the limiting plate 412, and the first limiting ring 413 is fixedly arranged on the inner side wall of the outer ring single-section ring 4117. The second limiting ring 414 is fixedly arranged on the side of the inner ring single-section ring 4116 away from the moving plate 42, and the second limiting ring 414 is arranged on the outer peripheral wall of the inner ring single-section ring 4116.

[0067] The first limiting ring 413 and the second limiting ring 414 may be made of a rigid material or a flexible material. The present embodiment does not limit the specific materials of the first limiting ring 413 and the second limiting ring 414 .

[0068] The implementation principle of a rainwater collection device for municipal gardens in the embodiment of the present application is as follows: Reference Figure 1 and Figure 3 , rainwater is transported to the telescopic cylinder 41 through the primary rainwater pipe 91 and the filter pipe 1. When the telescopic cylinder 41 is in a stretched state, that is, the telescopic cylinder 41 extends out of the outer periphery of the drainage cylinder 6, rainwater will pass through the water-permeable holes 4111 on the telescopic cylinder 41, and the rainwater will fall into the first step groove 21 of the water storage tank 2 for storage, while solids such as leaves, mud and sand in the rainwater will stay inside the telescopic cylinder 41.

[0069] When the first driving assembly 5 drives the telescopic cylinder 41 to move toward the first drop opening 4112, the length of the cylinder side wall of the telescopic cylinder 41 decreases gradually, so as to push the solid impurities on the cylinder side wall toward the first drop opening. After the rainwater flows out of the filter pipe 1, it will collide with the movable plate 42, and the rainwater after the collision will move along the cylinder side wall toward the first drop opening 4112, thereby pushing the solid impurities on the cylinder side wall into the first drop opening 4112, so as to reduce the occurrence of solid impurities blocking the water permeable hole 4111.

[0070] Reference Figure 3 In the process of filtering and collecting rainwater, the filtering mechanism 3 drives one telescopic cylinder 41 to be compressed and the other telescopic cylinder 41 to be stretched through the reciprocating motion of the moving plate 42; the stretched telescopic cylinder 41 has a longer cylinder side wall, and the stretched telescopic cylinder 41 plays a role in filtering rainwater; and the other telescopic cylinder 41 is compressed, so that the compressed telescopic cylinder 41 will automatically clean the solid impurities remaining inside.

[0071] To sum up: in the present technical solution, there is a matching relationship between the drainage cylinder 6, the movable plate 42 and the telescopic cylinder 41, so that while the rainwater collection device filters and collects rainwater, the telescopic cylinder 41 that performs a filtering function will be self-cleaned; to reduce the situation where solid impurities clog the water-permeable holes 4111 on the telescopic cylinder 41, to ensure the continuous operation of the rainwater collection device, and to increase the amount of rainwater collected by the rainwater collection device.

[0072] That is, the shapes, positions and connection relationships of the above-mentioned components are all set to satisfy the above-mentioned matching relationship, and the role of each component in the entire technical solution is also related to the above-mentioned matching relationship; the rainwater collection device can simultaneously perform rainwater filtering and collection work and self-cleaning work, so as to improve the performance of the rainwater collection device in long-term continuous operation.

[0073] Example 2 The difference between this embodiment 2 and embodiment 1 is that: Reference Figure 8 and Fig. 9 The filter assembly 4 also includes a reflecting plate 43, which is arranged in the telescopic cylinder 41. There are two reflecting plates 43, which are fixed on both sides of the movable plate 42. The reflecting plate 43 is arranged opposite to the first-level rainwater pipe 91, and a plurality of irregular protrusions 431 are provided on the surface of the reflecting plate 43; the rainwater in the first-level rainwater pipe 91 is jetted onto the reflecting plate 43, and the rainwater is reflected onto the single-section ring 411 by the reflecting plate 43.

[0074] The implementation principle of a rainwater collection device for municipal gardens in the embodiment of the present application is as follows: Reference Figure 8 and Fig. 9 When the movable plate 42 approaches the stop plate 412, the distance between the water outlet of the filter pipe 1 and the movable plate 42 decreases. Rainwater flows out of the filter pipe 1 and hits the irregular protrusions 431 on the reflective plate 43, so that the reflected water flow is ejected in different directions, so that the water flow can hit most areas on the side wall of the cylinder to clean out the sediment in the water permeable holes 4111, further improving the self-cleaning effect of the filter mechanism 3.

[0075] That is, the self-cleaning effect of the rainwater collection device is improved through the coordination of the movable plate 42, the telescopic cylinder 41 and the reflecting plate 43.

[0076] Example 3 The difference between this embodiment 3 and embodiment 1 is that: Reference Fig.10 and Fig.11 The single-section ring 411 is provided with a fracture line 4113 along the generatrix direction of the single-section ring 411. The fracture line 4113 runs through the single-section ring 411, the first limiting ring 413 and the second limiting ring 414. The fracture lines 4113 of several single-section rings 411 are located on the same plane. Under normal conditions, the fracture line 4113 of the single-section ring 411 is located at the lower edge of the single-section ring 411.

[0077] Reference Fig.12The single-section ring 411 is provided with a notch 4114, which is arranged on the side of the single-section ring 411 away from the moving plate 42, and the notch 4114 is connected with the fracture line 4113; the limiting plate 412 is provided with a push convex strip 415 on the side close to the moving plate 42, and the push convex strip 415 and the fracture line 4113 are located on the same plane; when the single-section ring 411 moves toward the limiting plate 412, the push convex strip 415 is inserted into the notch 4114, and the push convex strip 415 forces the single-section ring 411 to open a second drop opening 4115 along the fracture line 4113, and the drainage tube 6 is used to receive rainwater falling from the second drop opening 4115. It is worth noting that in this embodiment, there are limit stops between adjacent single-section rings 411, so that adjacent single-section rings 411 can slide relative to each other in the horizontal direction, and adjacent single-section rings 411 cannot rotate relative to each other, so as to ensure the alignment between the push convex strip 415 and the fracture line 4113. The limiting effect between the single-section rings 411 can be achieved by the cooperation of limiting convex strips and limiting grooves, or by setting limiting blocks on adjacent single-section rings 411; the present application does not limit the specific limiting method between the single-section rings 411.

[0078] Reference Fig.11 and Fig.12 In this embodiment, the first limiting ring 413 and the second limiting ring 414 are made of flexible materials, thereby reserving deformation space for the outward expansion deformation of the single-section ring 411. When the single-section ring 411 expands outward, the first limiting ring 413 and the second limiting ring 414 are compressed and deformed. The material of the first limiting ring 413 and the second limiting ring 414 can be a material with compression deformation performance such as foam rubber-plastic board, pearl cotton, rubber, corrugated board, etc., and the material also has a certain supporting effect. In this embodiment, the first limiting ring 413 and the second limiting ring 414 are made of foam rubber plate material; and the outside of the foam rubber plate is covered with a protective film.

[0079] The implementation principle of a rainwater collection device for municipal gardens in the embodiment of the present application is as follows: Reference Fig.11 and Fig.12 When the telescopic cylinder 41 is in the state of filtering solid impurities, the side wall of the telescopic cylinder 41 is a continuous surface to ensure the filtering function of the telescopic cylinder 41. When the telescopic cylinder 41 is in the self-cleaning state, the push convex strip 415 passes through the notch 4114 of the telescopic cylinder 41, and can force the side wall of the cylinder to open a second drop opening 4115 along the fracture line 4113. Therefore, when rainwater is reflected to the telescopic cylinder 41 by the moving plate 42, the rainwater will carry solid impurities and fall from the second drop opening 4115 to the drainage cylinder 6, so as to further improve the self-cleaning effect of the telescopic cylinder 41.

[0080] That is, through the coordination relationship among the pushing convex strip 415, the telescopic cylinder 41 and the movable plate 42; when the rainwater collection device cleans the telescopic cylinder 41, multiple single-section rings 411 can simultaneously open the second drop opening 4115 to facilitate the drop of solid impurities remaining on each single-section ring 411, so as to further improve the self-cleaning effect of the telescopic cylinder 41.

[0081] Example 4 The difference between this embodiment 4 and embodiment 3 is that: Reference Fig.13 When the telescopic cylinder 41 is in the working state of filtering rainwater, in order to ensure the sealing performance of the telescopic cylinder 41 at the fracture line 4113, the telescopic cylinder 41 further includes an elastic sealing strip 417, two of which are arranged on both sides of the fracture line 4113, and the elastic sealing strip 417 is fixedly connected to the single-section ring 411. When the telescopic cylinder 41 is in the working state of filtering rainwater, the two elastic sealing strips 417 are closely abutted to improve the sealing performance of the single-section ring 411 in the fracture line 4113 area.

[0082] The elastic sealing strip 417 can be made of elastic materials such as rubber and silicone. In the present embodiment, the elastic sealing strip 417 is made of rubber material. After the elastic sealing strip 417 is plugged and fixed to the single-section ring 411, the elastic sealing strip 417 and the single-section ring 411 are fixedly connected by hot melt adhesive.

[0083] Example 5 The difference between this embodiment 5 and embodiment 3 is that: Reference Fig.14 and Fig.15 The filtering mechanism 3 further includes a second driving assembly 7, which is fixed on the side wall of the water storage tank 2. In this embodiment, the telescopic cylinder 41 is rotatably connected to the moving plate 42, and the second driving assembly 7 is used to drive the telescopic cylinder 41 to rotate. When the telescopic cylinder 41 of the second driving assembly 7 rotates, a plurality of single-section rings 411 rotate synchronously.

[0084] Reference Fig.14 and Fig.15 In this embodiment, the second drive assembly 7 is arranged just above the telescopic cylinder 41, and the second drive assembly 7 includes a motor 71, a gear 72 and a ring gear 73; the motor 71 is fixedly arranged on the outer peripheral wall of the water storage tank 2, and the side wall of the water storage tank 2 is provided with a mounting hole for the rotating shaft to pass through, the rotating shaft is fixedly connected to the motor 71, and the gear 72 is fixedly arranged on the side of the rotating shaft away from the motor 71. The ring gear 73 is fixedly arranged on the outer peripheral wall of the telescopic cylinder 41, and the ring gear 73 is meshed with the gear 72; so as to achieve the purpose of the second drive assembly 7 driving the telescopic cylinder 41 to rotate.

[0085] In this embodiment, the motor 71 is a reversible motor 71 (also called a forward and reverse motor 71), which can change the direction of rotation from forward to reverse or from reverse to forward in an instant. The second drive assembly 7 can drive the telescopic cylinder 41 to reciprocate clockwise and counterclockwise. For example, the telescopic cylinder 41 first rotates 10° clockwise, then rotates 20° counterclockwise, and then rotates 20° clockwise, etc. to drive the telescopic cylinder 41 to swing back and forth in a small amplitude. The second drive assembly 7 drives the telescopic cylinder 41 to rotate, and the rotating telescopic cylinder 41 forces the solid impurities in the rainwater to move toward the first drop port 4112 and the second drop port 4115.

[0086] That is, by alternately operating the first drive assembly 5 and the second drive assembly 7 , the filtered solid impurities can be caused to fall into the drainage tube 6 through the first drop port 4112 and the second drop port 4115 , so as to further improve the self-cleaning effect of the filter mechanism 3 .

[0087] Reference Figures 15 to 17 The rainwater collection device also includes a cleaning mechanism 8, which includes a cleaning cover 81, a connecting seat 82, a water pipe 83, a water hose 84 and a spring member 85. When the telescopic cylinder 41 is compressed to the length of a single-section ring 411, the cleaning cover 81 is arranged on the outer periphery of the telescopic cylinder 41, and the cleaning cover 81 abuts against the movable plate 42. The connecting seat 82 is arranged on the side of the cleaning cover 81 close to the telescopic cylinder 41, and the water pipe 83 is spherically hinged to the connecting seat 82. One end of the water hose 84 is connected to the water pipe 83, and the other end of the water hose 84 is externally connected to the water supply pipeline; after the water is output through the water pipe 83, the rainwater is jetted to the cleaning cover 81 and the telescopic cylinder 41. One end of the elastic member is fixedly connected to the water pipe 83, and the other end of the elastic member is fixedly connected to the cleaning cover 81. A spherical protrusion 86 is provided on the outer periphery of the telescopic cylinder 41 , and the spherical protrusion 86 is used to force the water delivery steel pipe 83 to rotate around the hinge point of the water delivery steel pipe 83 .

[0088] Reference Fig.18 In this embodiment, an annular groove 432 is provided on the reflector 43. When the telescopic cylinder 41 is compressed to the length of a single ring 411, the filter pipe 1 is inserted into the annular groove 432, and the reflector 43 blocks the filter pipe 1. The water hose 84 is connected to the filter pipe 1, and the diameter of the filter pipe 1 is smaller than the diameter of the water hose 84, so as to increase the flow rate of the water in the water hose 84 and the water steel pipe 83, and increase the degree of collision between the water flow and the telescopic cylinder 41. The filter pipe 1 is inserted into the annular groove 432, so that the reflector 43 blocks the filter pipe 1; the water in the middle of the filter pipe 1 is ejected through the water hose 84 and the delivery steel pipe, thereby utilizing the rainwater ejection telescopic pipe in the filter pipe 1, reducing the installation of external water supply equipment, and saving water resources.

[0089] Reference Fig.17 In this embodiment, the diameter of the water-permeable holes 4111 on the single-section ring 411 increases gradually along the vertical upward direction, so that high-speed water flows through the single-section ring 411 arranged on the outside and jets to the single-section ring 411 inside.

[0090] The implementation principle of a rainwater collection device for municipal gardens in the embodiment of the present application is as follows: Reference Fig.16 and Fig.17 When the telescopic cylinder 41 is compressed to the length of a single-section ring 411, the telescopic cylinder 41 is in a self-cleaning state; after the water is ejected through the delivery steel pipe, it will directly hit the telescopic cylinder 41, or hit the telescopic cylinder 41 after being reflected by the cleaning cover 81. The water with a large flow rate can hit the telescopic cylinder 41 from the outside of the telescopic cylinder 41, and hit the solid impurities in the water permeable hole 4111; and make the telescopic cylinder 41 vibrate to shake off the solid impurities on the side wall of the cylinder, so that the solid impurities on the side wall of the cylinder can fall from the first drop opening 4112 and the second drop opening 4115.

[0091] At the same time, when the telescopic cylinder 41 drives the spherical protrusion 86 to rotate, the spherical protrusion 86 forces the water delivery steel pipe 83 to rotate around the connecting seat 82, so that the water delivery steel pipe 83 can spray water in different directions, thereby improving the cleaning effect of the cleaning mechanism 8 on the telescopic cylinder 41.

[0092] When the telescopic cylinder 41 is in the self-cleaning state, the second driving assembly 7 drives the telescopic cylinder 41 to rotate, so that the water flow ejected by the cleaning mechanism 8 can cover more surface area of ​​the telescopic cylinder 41, thereby improving the cleaning effect of the cleaning mechanism 8 on the telescopic cylinder 41.

[0093] It is worth noting that in order to improve the simplicity of the drawings in the specification, in the present embodiment, there is only one conveying steel pipe; while in other embodiments, multiple conveying steel pipes may be provided, and the multiple conveying steel pipes face different directions.

[0094] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
