Description

TECHNICAL FIELD

[0001] The application relates to the technical field of municipal engineering, in particular to rainwater collecting equipment for municipal gardens. BACKGROUND

[0002] The rainwater collecting equipment for municipal gardens is a device for collecting and utilizing rainwater to make full use of natural resources and save water resources.

[0003] The rainwater collecting equipment collects rainwater from a rainwater collecting surface (hardened ground, green land and the like in gardens), filters, deposits and purifies the rainwater, stores the treated rainwater in a water storage facility (for example, a water storage pool, a water tower and the like), and uses the stored rainwater to irrigate flowers, plants and trees, replenish landscape water and flush toilets through a water distribution system.

[0004] Since rainwater in municipal gardens flows through a large area of green land, rainwater filtering devices such as rainwater grates can only filter large-area leaves and other impurities, so that rainwater collected by rainwater pipelines contains small-area leaves, silt and other solid impurities.

[0005] In the prior art, a filter screen is usually arranged in the rainwater collecting equipment to filter out solid impurities in rainwater. However, when the soil in municipal gardens has a large sand content and rainwater washes the ground to a large extent, rainwater contains a large amount of solid impurities, so that small-particle solid impurities block the holes of the filter screen, thereby affecting the collection of rainwater. SUMMARY

[0006] In order to reduce the occurrence of the condition that impurities in rainwater block the rainwater collecting equipment and improve the continuous rainwater collecting capacity of the rainwater collecting equipment, the application provides rainwater collecting equipment for municipal gardens.

[0007] The rainwater collecting equipment for municipal gardens provided by the application adopts the following technical scheme:

[0008] The rainwater collecting equipment for municipal gardens is characterized in that rainwater in municipal gardens is collected by a rainwater surface and flows into a primary rainwater pipeline;

[0009] The rainwater collecting equipment comprises a filter pipeline, a water storage pool and a filter mechanism, the filter mechanism is fixed to the inner side wall of the water storage pool, the filter pipeline is in communication with the primary rainwater pipeline, and the filter pipeline delivers rainwater to the filter mechanism;

[0010] The filtering mechanism comprises a filtering assembly, a first driving assembly and a drainage cylinder; the filtering assembly is fixed to the inner side wall of the water storage pool, the filtering assembly comprises telescopic cylinders and a moving plate, the two telescopic cylinders are arranged on the two sides of the moving plate, the filtering pipeline extends into the telescopic cylinders and is away from the moving plate, the diameter of the telescopic cylinder increases along the direction away from the moving plate, the cylinder side wall of the telescopic cylinder is provided with a plurality of water permeable holes, 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 moving plate, and the moving plate is used to drive the telescopic cylinder to compress or elongate; the first driving assembly is fixed to the water storage pool, and the first driving assembly is used to drive the moving plate to move horizontally, when the moving plate moves horizontally, one telescopic cylinder is compressed and the other telescopic cylinder is elongated; the drainage cylinder is fixed in the water storage pool, the drainage cylinder is arranged directly below the first drop opening, the drainage cylinder is used to receive the rainwater falling from the first drop opening, and the drainage cylinder circumscribes a secondary rainwater pipeline.

[0011] By adopting the above technical scheme, rainwater is transported to the telescopic cylinder in the elongated state through the primary rainwater pipeline and the filtering pipeline, the rainwater penetrates the water permeable holes arranged on the telescopic cylinder, the rainwater falls into the water storage pool for storage, and the solid in the rainwater, such as leaves and silt, stays in the telescopic cylinder. When the first driving assembly drives the telescopic cylinder to move towards the first drop opening, the length of the cylinder side wall of the telescopic cylinder decreases, so as to push the solid impurities on the cylinder side wall towards the first drop hole. After the rainwater flows out of the filtering pipeline, the rainwater collides with the moving plate, the rainwater after the collision moves along the cylinder side wall towards the first drop opening, so as to push the solid impurities on the cylinder side wall into the first drop opening, thereby reducing the situation that the solid impurities block the water permeable holes.

[0012] During the filtering and collecting of rainwater by the filtering mechanism, the reciprocating movement of the moving plate drives one telescopic cylinder to compress and the other telescopic cylinder to stretch; the telescopic cylinder in the stretched state has a longer cylinder side wall, and the telescopic cylinder in the stretched state plays a role in filtering rainwater; and the other telescopic cylinder is compressed, so that the telescopic cylinder in the compressed state automatically cleans the solid impurities remaining in the inside.

[0013] In the rainwater collecting equipment in the technical scheme, the telescopic cylinder for filtering rainwater is self-cleaned while the rainwater collecting equipment filters and collects rainwater, so as to reduce the situation that the solid impurities block the water permeable holes on the telescopic cylinder, to ensure the continuous operation of the rainwater collecting equipment and improve the rainwater collecting capacity of the rainwater collecting equipment.

[0014] Optionally, the telescopic cylinder comprises single joint rings, a limiting plate, a first limiting ring and a second limiting ring; the single joint rings are provided in plurality, and the diameters of the single joint rings increase in the direction away from the moving plate; the plurality of single joint rings are slidably connected; the first limiting ring is fixedly arranged on the outer side of the single joint ring, and the first limiting ring is arranged on the side of the single joint ring away from the moving plate; the second limiting ring is fixedly arranged on the inner side of the single joint ring, and the second limiting ring is arranged on the side of the single joint ring close to the moving plate; the first limiting ring is used for abutting against the second limiting ring; the limiting plate is arranged on the side of the telescopic cylinder away from the moving plate, and the limiting plate is fixedly connected with the single joint ring; and the limiting ring is used for abutting against the plurality of single joint rings.

[0015] By adopting the above technical scheme, the plurality of single joint rings are slidably connected, and the adjacent single joint rings are connected in a sealed manner through the first limiting ring and the second limiting ring; thus, the compression deformation and the tensile deformation of the telescopic cylinder are facilitated.

[0016] Optionally, the single joint ring is provided with a fracture line along the generatrix direction of the single joint ring; the fracture lines of the plurality of single joint rings are located on the same plane; the single joint ring is provided with a notch, the notch is arranged on the side of the single joint ring away from the moving plate, and the notch is in communication with the fracture line; the side of the limiting plate close to the moving plate is provided with a pushing protrusion, and the pushing protrusion is located on the same plane as the fracture line; when the single joint ring moves towards the limiting plate, the pushing protrusion is inserted into the notch, the pushing protrusion forces the single joint ring to open along the fracture line to form a second falling opening, and the drain pipe is used for receiving the rainwater falling from the second falling 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 when the single joint ring expands.

[0017] By adopting the above technical scheme, when the telescopic cylinder is in a filtering solid impurity state, 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 a self-cleaning state, the pushing protrusion can force the side wall to open along the fracture line to form a second falling opening through the notch of the telescopic cylinder; thus, when the rainwater is reflected by the moving plate to the telescopic cylinder, the rainwater carrying the solid impurities falls from the second falling opening to the drain pipe, so as to improve the self-cleaning effect of the telescopic cylinder.

[0018] Optionally, the telescopic cylinder further comprises elastic sealing strips, the elastic sealing strips are provided in two, the elastic sealing strips are arranged on the two sides of the fracture line, and the elastic sealing strips are fixedly connected with the single joint ring; when the telescopic cylinder is in a working state of filtering rainwater, the two elastic sealing strips are in close abutment.

[0019] By adopting the technical scheme, the two elastic sealing strips are tightly abutted, and the sealing performance of the telescopic cylinder at the breaking line is ensured.

[0020] Optionally, the filtering assembly further comprises a reflecting plate, the reflecting plate is arranged in the telescopic cylinder, the reflecting plate is provided with two, the two reflecting plates are fixedly arranged on the two sides of the moving plate, the reflecting plate is arranged opposite to the primary rainwater pipeline, and the surface of the reflecting plate is provided with a plurality of irregular protrusions; rainwater in the primary rainwater pipeline is jetted onto the reflecting plate, and the rainwater is reflected to the single-link ring by the reflecting plate.

[0021] By adopting the technical scheme, when the rainwater flows out of the filtering pipeline and impacts the irregular protrusions on the reflecting plate, the reflected water flow is jetted in different directions, so that the water flow can impact most of the areas on the cylinder side wall to clean the silt in the water-permeable holes, and the self-cleaning effect of the filtering mechanism is further improved.

[0022] Optionally, the rainwater collecting device further comprises a cleaning mechanism, the cleaning mechanism comprises a cleaning cover, a connecting seat, a water conveying steel pipe and a water conveying hose; when the telescopic cylinder is compressed to one single-link ring, the cleaning cover is arranged on the outer periphery of the telescopic cylinder and abuts against the moving plate; the connecting seat is arranged on the side of the cleaning cover close to the telescopic cylinder, the water conveying steel pipe is connected to the connecting seat, one end of the water conveying hose is connected to the water conveying steel pipe in communication, and the other end of the water conveying hose is connected to a water body supply pipeline; after the water body is output through the water conveying steel pipe, the rainwater body is jetted to the cleaning cover and the telescopic cylinder.

[0023] By adopting the technical scheme, when the telescopic cylinder is compressed to the length of one single-link ring and is in the self-cleaning state, after the water body is jetted out through the conveying steel pipe, the water body directly impacts the telescopic cylinder or impacts the telescopic cylinder after being reflected by the cleaning cover. The water body with a large flow rate can impact the telescopic cylinder from the outside of the telescopic cylinder and impact the solid impurities in the water-permeable holes; so that the telescopic cylinder vibrates to shake off the solid impurities on the cylinder side wall, so that the solid impurities on the cylinder side wall can fall from the first falling opening.

[0024] Optionally, the reflecting plate is provided with a ring groove, the filtering pipeline is inserted into the ring groove when the telescopic cylinder is compressed to one single-link ring, and the reflecting plate blocks the filtering pipeline; the water conveying hose is connected to the filtering pipeline in communication, and the diameter of the filtering pipeline is smaller than the diameter of the water hose.

[0025] By adopting the technical scheme, when the moving plate moves towards the first drop opening direction, the filter pipe is inserted into the annular groove, so that the reflecting plate blocks the filter pipe; thus, no water flow acts on the inside of the filter pipe. When the cleaning mechanism sprays water flow from the outer periphery of the telescopic cylinder, the water flow collides with the outer sidewall of the telescopic cylinder, so as to increase the vibration degree of the telescopic cylinder, so that the solid impurities on the telescopic cylinder fall off, and the self-cleaning effect of the telescopic cylinder is further improved.

[0026] Meanwhile, the reflecting plate blocks the filter pipe, so that the water in the middle of the filter pipe is jetted through the water supply hose and the conveying steel pipe, so as to utilize the rainwater jet telescopic pipe in the filter pipe to reduce the installation of external water body supply equipment and save water resources.

[0027] Optionally, the cleaning mechanism further comprises a spring member, one end of the spring member is fixedly connected with the water conveying steel pipe, and the other end of the spring member is fixedly connected with the cleaning cover; and the water conveying steel pipe is spherically connected with the connecting seat.

[0028] By adopting the technical scheme, the water conveying steel pipe is spherically connected with the connecting seat, so that when the water body is jetted out from the water conveying steel pipe, the water conveying steel pipe rotates with the connecting seat, so that the water conveying steel pipe can spray water flow towards different directions, and the cleaning effect of the cleaning mechanism on the telescopic cylinder is improved.

[0029] Optionally, the filter mechanism further comprises a second driving assembly, the second driving assembly is used for driving the telescopic cylinder to rotate; and a spherical protrusion is arranged on the outer periphery of the telescopic cylinder, and the spherical protrusion is used for forcing the water conveying steel pipe to rotate around the hinge point of the water conveying steel pipe.

[0030] By adopting the technical scheme, when the telescopic cylinder drives the spherical protrusion to rotate, the spherical protrusion forces the water conveying steel pipe to rotate around the connecting seat, so that the water conveying steel pipe can spray water flow towards different directions, and the cleaning effect of the cleaning mechanism on the telescopic cylinder is improved.

[0031] Optionally, the filter mechanism further comprises a second driving assembly, the second driving assembly is used for driving the telescopic cylinder to rotate.

[0032] By adopting the technical scheme, the second driving assembly drives the telescopic cylinder to rotate, and the rotating telescopic cylinder forces the solid impurities in the rainwater to move towards the first drop opening direction, so as to improve the self-cleaning effect of the filter mechanism. When the telescopic cylinder is in the self-cleaning state, the second driving assembly drives the telescopic cylinder to rotate, so that the water flow sprayed by the cleaning mechanism can cover more surface area of the telescopic cylinder, so as to improve the cleaning effect of the cleaning mechanism on the telescopic cylinder.

[0033] In summary, the present application has at least one of the following beneficial technical effects:

[0034] 1. While filtering and collecting rainwater, the rainwater harvesting equipment will self-clean the telescopic cylinder that plays a filtering role, thereby reducing the situation where solid impurities clog the water permeable holes on the telescopic cylinder, ensuring the continuous operation of the rainwater harvesting equipment and increasing the amount of rainwater collected by the rainwater harvesting equipment.

[0035] 2. When the telescopic cylinder is in the state of filtering solid impurities, the side wall of the cylinder is a continuous surface to ensure its filtration function. When the telescopic cylinder is in the self-cleaning state, the pushing protrusion, through the notch in the cylinder, forces the side wall to open along the fracture line to create a second drop outlet. Thus, when rainwater is reflected onto the telescopic cylinder by the moving plate, the rainwater carrying solid impurities will fall from the second drop outlet into the drainage cylinder, improving the self-cleaning effect of the telescopic cylinder.

[0036] 3. When the telescopic cylinder is compressed to the length of a single ring and is in a self-cleaning state, the water ejected through the conveying steel pipe will directly impact the telescopic cylinder, or be reflected by the cleaning hood before impacting the telescopic cylinder. Water with a higher flow velocity may impact the telescopic cylinder from the outside, as well as impact solid impurities in the permeable holes; this will cause the telescopic cylinder to vibrate, shaking off solid impurities on the cylinder sidewall, thus facilitating the falling of solid impurities from the first drop outlet.

[0057] Example 1

[0058] The embodiment of the present application discloses a rainwater collecting device for municipal gardens. Rainwater in the municipal gardens is collected by a rainwater surface (hardened ground, green land and the like in the gardens) and flows into a first rainwater pipeline 91. Since the rainwater in the municipal gardens flows through a large area of green land, and a rainwater filter device such as a rainwater grate can only filter large-area leaves and other impurities, the rainwater collected by the first rainwater pipeline 91 contains small-area leaves, silt and other small-particle solid impurities.

[0059] Referring to Figure 1 and Figure 2 , the first rainwater pipeline 91 is connected with the rainwater collecting device of the embodiment of the present application, and the rainwater collecting device is used for filtering solid impurities in the rainwater; the rainwater collecting device is further connected with a second rainwater pipeline 92, and the second rainwater pipeline 92 is connected with a municipal rainwater pipeline; the rainwater collecting device is used for collecting part of clean rainwater, and the excess rainwater, impurities and the like are discharged into the municipal rainwater pipeline through the second rainwater pipeline 92. In the drawings of the present application, the arrow direction represents the flowing direction of the water flow.

[0060] Referring to Figure 1 and Figure 2 , the rainwater collecting device for the municipal gardens comprises a filter pipeline 1, a water storage pool 2 and a filter mechanism 3.

[0061] Referring to Figure 1 and Figure 2 , the water storage pool 2 is internally provided with a stepped groove, which comprises a first stepped groove 21 and a second stepped groove 22 along the vertical upward direction, and the cross-sectional area of the first stepped groove 21 is smaller than that of the second stepped groove 22; the second stepped groove 22 is provided with a mounting seat on the groove bottom wall for mounting the filter mechanism 3, and the first stepped groove 21 is used for storing filtered rainwater. The water storage pool 2 can also be connected with a pool body or a water storage tank with a larger storage space, so as to collect more rainwater.

[0062] Referring to Figure 1 and Figure 2 , the filter mechanism 3 is fixedly arranged on the inner side wall of the water storage pool 2, and the filter mechanism 3 is arranged on the mounting seat of the groove bottom wall of the second stepped groove 22. The filter pipeline 1 is connected with the first rainwater pipeline 91, the pool side wall of the water storage pool 2 is provided with a through hole for penetrating the filter pipeline 1, and the filter pipeline 1 conveys the rainwater collected by the first rainwater pipeline 91 to the filter mechanism 3.

[0063] Referring to Figure 2 and Figure 3 , the filter mechanism 3 comprises a filter assembly 4, a first driving assembly 5 and a drain barrel 6.

[0064] Referring to Figure 2 and Figure 3The filtering assembly 4 is fixed to the inner side wall of the water storage pool 2, and the filtering assembly 4 comprises telescopic cylinders 41 and a moving plate 42. The telescopic cylinders 41 are fixed to the two sides of the moving plate 42, and the central axes of the telescopic cylinders 41 are horizontally arranged. The moving plate 42 is used for compressing or stretching the telescopic cylinders 41 to change the length of the telescopic cylinders 41. The filtering pipeline 1 is arranged in the telescopic cylinders 41, and the filtering pipeline 1 extends into the inner chambers of the telescopic cylinders 41.

[0065] With reference to Figure 3 and Figure 4 , the first driving assembly 5 is fixed to the water storage pool 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 axes of the telescopic cylinders 41. The first driving assembly 5 is used for driving the moving plate 42 to move horizontally. When the moving plate 42 moves horizontally, one telescopic cylinder 41 is compressed, and the other telescopic cylinder 41 is stretched. In the embodiment, the telescopic cylinder 41 on the left side of the moving plate 42 is in a compressed state, and the telescopic cylinder 41 on the right side of the moving plate 42 is in a stretched state. When the moving plate 42 moves to the right, the telescopic cylinder 41 on the left side of the moving plate 42 is stretched to the middle area of the water storage pool 2, and the length of the telescopic cylinder 41 on the left side of the moving plate 42 becomes longer. The telescopic cylinder 41 on the right side of the moving plate 42 moves to the side wall of the water storage pool 2, and the length of the telescopic cylinder 41 on the right side of the moving plate 42 becomes shorter.

[0066] The first driving assembly 5 can be a gas cylinder, an electric push rod, an oil cylinder or the like linear reciprocating driving member. In the embodiment, the first driving assembly 5 is a gas cylinder. The number of the first driving assembly 5 can be one, two or three, etc. In the embodiment, the first driving assembly 5 is provided with one, and in other embodiments, the first driving assembly 5 can be provided with two symmetrically along the moving plate 42.

[0067] With reference to Figure 3 and Figure 4 , the telescopic cylinder 41 comprises single-joint rings 411, limiting plates 412, first limiting rings 413 and second limiting rings 414.

[0068] With reference to Figure 3 and Figure 4 , the single-joint rings 411 are provided with a plurality of single-joint rings 411, and the diameters of the single-joint rings 411 increase in the direction away from the moving plate 42. The plurality of single-joint rings 411 are slidably connected. Thus, the compression and stretching of the telescopic cylinders 41 can be realized by the horizontal movement of the moving plate 42. The side wall of the single-joint ring 411 is provided with a plurality of water-permeable holes 4111 for filtering solid impurities in the rainwater. It is worth noting that, in order to reflect the water-permeable holes 4111 in the single-joint ring 411, the drawings of the present application are exaggerated to reflect the water-permeable holes 4111 in the single-joint ring 411.

[0069] With reference to Figure 4The limiting plate 412 is arranged on the side of the telescopic cylinder 41 away from the moving plate 42, and the limiting plate 412 is fixedly connected with the single-link ring 411, and the limiting ring is used for abutting with the plurality of single-link rings 411. Therefore, when the moving plate 42 and the limiting plate 412 are close to each other, the moving plate 42 and the limiting plate 412 will extrude the telescopic cylinder 41, so that the plurality of single-link rings 411 are stacked to compress the telescopic cylinder 41.

[0070] With reference to Figure 3 and Figure 4 In the embodiment, the single-link ring 411 fixed with the limiting plate 412 is provided with a first drop opening 4112 for dropping the rainwater containing solid impurities. The drainage cylinder 6 is fixedly arranged below the first drop opening 4112, and the drainage cylinder 6 is used for receiving the rainwater containing solid impurities. The drainage cylinder 6 is connected with the secondary rainwater pipeline 92 to drain the rainwater containing more solid impurities out of the rainwater collecting device.

[0071] With reference to Figure 5 and Figure 6 The telescopic cylinder 41 is bent on the side away from the moving plate 42 to form a fixed groove 416, and the inner side wall of the water storage pool 2 is fixedly provided with a support 23 which is inserted into the fixed groove 416, so that the filtering assembly 4 is horizontally fixed on the inner side wall of the water storage pool 2 and the displacement of the side of the telescopic cylinder 41 away from the moving plate 42 is limited. The support 23 can be a metal block, a roller or other components with supporting function. In the embodiment, the support 23 is a metal block which is fixed on the side wall of the water storage pool 2. The connection mode of the telescopic cylinder 41 and the moving plate 42 can be welding, rotating connection, and the embodiment does not limit the specific connection mode of the telescopic cylinder 41 and the moving plate 42.

[0072] With reference to Figure 3 and Figure 4 The first limiting ring 413 and the second limiting ring 414 are arranged between the adjacent single-link rings 411 to limit the sliding connection between the adjacent single-link rings 411.

[0073] With reference to Figure 7 In the embodiment, for the convenience of description, the single-link ring 411 with smaller diameter among the adjacent single-link rings 411 is named as the inner single-link ring 4116, and the single-link ring 411 with larger diameter is named as the outer single-link ring 4117. The first limiting ring 413 is fixedly arranged on the side of the outer single-link 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 single-link ring 4117. The second limiting ring 414 is fixedly arranged on the side of the inner single-link ring 4116 away from the moving plate 42, and the second limiting ring 414 is arranged on the outer peripheral wall of the inner single-link ring 4116.

[0074] The first limiting ring 413 and the second limiting ring 414 can be made of rigid materials or flexible materials, and the embodiment does not limit the specific material of the first limiting ring 413 and the second limiting ring 414.

[0075] The implementation principle of the rainwater collecting equipment for municipal gardens in the embodiment of the application is as follows:

[0076] Referring to Figure 1 and Figure 3 , the rainwater is transported to the telescopic cylinder 41 through the first rainwater pipeline 91 and the filter pipeline 1. When the telescopic cylinder 41 is in the stretched state, that is, the telescopic cylinder 41 extends out of the outer periphery of the drainage cylinder 6, the rainwater will pass through the water-permeable hole 4111 arranged on the telescopic cylinder 41, and the rainwater will fall into the first step groove 21 of the water storage pool 2 for storage, while the leaves, sand and other solids in the rainwater will stay inside the telescopic cylinder 41.

[0077] When the first driving assembly 5 drives the telescopic cylinder 41 to move towards the first drop opening 4112, the length of the cylinder side wall of the telescopic cylinder 41 decreases, so as to push the solid impurities on the cylinder side wall towards the first drop hole. After the rainwater flows out of the filter pipeline 1, the rainwater will collide with the moving plate 42, and the rainwater after the collision will move along the cylinder side wall towards the first drop opening 4112, so as to push the solid impurities on the cylinder side wall into the first drop opening 4112, so as to reduce the situation that the solid impurities block the water-permeable hole 4111.

[0078] Referring to Figure 3 , during the filtering and collecting of the rainwater, the filter mechanism 3 drives one telescopic cylinder 41 to compress and another telescopic cylinder 41 to stretch through the reciprocating movement of the moving plate 42; the telescopic cylinder 41 after stretching has a longer cylinder side wall, and the telescopic cylinder 41 after stretching plays a role in filtering the rainwater; and the other telescopic cylinder 41 is compressed, so that the telescopic cylinder 41 after compression will automatically clean the solid impurities remaining inside.

[0079] In summary: in the technical solution, there is a matching relationship between the drainage cylinder 6, the moving plate 42 and the telescopic cylinder 41, so that the telescopic cylinder 41 playing a filtering role is self-cleaned while the rainwater collecting equipment is filtering and collecting the rainwater, so as to reduce the situation that the solid impurities block the water-permeable hole 4111 of the telescopic cylinder 41, so as to ensure the continuous work of the rainwater collecting equipment and improve the rainwater collecting amount of the rainwater collecting equipment.

[0080] That is, the shape, position and connection relationship of each component are all set to meet the above matching relationship, and the role of each component in the entire technical solution is also related to the above matching relationship; so that the rainwater collecting equipment synchronously performs the rainwater filtering and collecting work and the self-cleaning work, so as to improve the performance of the rainwater collecting equipment for long-time continuous work.

[0081] Embodiment 2

[0082] The difference between this embodiment 2 and embodiment 1 is that:

[0083] With reference to Figure 8 and Figure 9 , the filtering assembly 4 further comprises a reflecting plate 43, the reflecting plate 43 is arranged in the telescopic cylinder 41, the reflecting plate 43 is provided with two, the two reflecting plates 43 are fixedly arranged on the two sides of the moving plate 42, the reflecting plate 43 is arranged opposite to the first rainwater pipeline 91, and the reflecting plate 43 is provided with a plurality of irregular protrusions 431 on the surface; the rainwater jet in the first rainwater pipeline 91 is reflected to the single-joint ring 411 on the reflecting plate 43.

[0084] The implementation principle of the rainwater collecting equipment for municipal gardens in the embodiment of the application is:

[0085] With reference to Figure 8 and Figure 9 , when the moving plate 42 is close to the limiting plate 412, the distance between the water outlet of the filtering pipeline 1 and the moving plate 42 decreases. The rainwater flows out of the filtering pipeline 1 and impacts the irregular protrusions 431 on the reflecting plate 43, so that the reflected water flow is shot in different directions, so that the water flow can impact most of the areas on the side wall of the cylinder to clean the silt in the water-permeable holes 4111, and the self-cleaning effect of the filtering mechanism 3 is further improved.

[0086] That is, through the cooperation of the moving plate 42, the telescopic cylinder 41 and the reflecting plate 43, the self-cleaning effect of the rainwater collecting equipment is improved.

[0087] Embodiment 3

[0088] The difference between this embodiment 3 and embodiment 1 is that:

[0089] With reference to Figure 10 and Figure 11 , the single-joint ring 411 is provided with a fracture line 4113 along the generatrix direction of the single-joint ring 411, the fracture line 4113 penetrates the single-joint ring 411, the first limiting ring 413 and the second limiting ring 414, and the fracture lines 4113 of the plurality of single-joint rings 411 are located on the same plane. Under normal circumstances, the fracture line 4113 of the single-joint ring 411 is located at the lower edge of the single-joint ring 411.

[0090] With reference to Figure 12, the single-link ring 411 is provided with a notch 4114 arranged on the side of the single-link ring 411 away from the moving plate 42, and the notch 4114 is in communication with the fracture line 4113; the limiting plate 412 is provided with a pushing protrusion 415 on the side close to the moving plate 42, and the pushing protrusion 415 is located in the same plane as the fracture line 4113; when the single-link ring 411 moves towards the limiting plate 412, the pushing protrusion 415 is inserted into the notch 4114, and the pushing protrusion 415 forces the single-link ring 411 to open along the fracture line 4113 to form a second drop opening 4115, and the drain barrel 6 is used to receive the rainwater dropped from the second drop opening 4115. It is worth noting that in the embodiment, the adjacent single-link rings 411 are provided with a limiting function, so that the adjacent single-link rings 411 can move relatively along the horizontal direction, and the adjacent single-link rings 411 cannot rotate relatively, so as to ensure the alignment between the pushing protrusion 415 and the fracture line 4113. The limiting effect between the single-link rings 411 can be realized by the cooperation of the limiting protrusions and the limiting grooves, or the limiting blocks can be arranged on the adjacent single-link rings 411; the specific limiting mode between the single-link rings 411 is not limited in the application.

[0091] With reference to Figure 11 and Figure 12 In the embodiment, the first limiting ring 413 and the second limiting ring 414 are made of flexible materials, thereby reserving a deformation space for the outward expansion deformation of the single-link ring 411. When the single-link ring 411 expands outward, the first limiting ring 413 and the second limiting ring 414 are compressed and deformed. The materials of the first limiting ring 413 and the second limiting ring 414 can be foamed rubber plates, pearl wool, rubber, corrugated plates and other materials with compression deformation performance, and the materials also have a certain supporting effect. In the embodiment, the first limiting ring 413 and the second limiting ring 414 are made of foamed rubber plate materials, and the foamed rubber plates are covered with protective films.

[0092] The implementation principle of the rainwater collecting equipment for municipal gardens in the embodiment of the application is as follows:

[0093] With reference to Figure 11 and Figure 12 When the telescopic cylinder 41 is in the state of filtering solid impurities, the cylinder side wall of the telescopic cylinder 41 is a continuous surface, so as to ensure the filtering function of the telescopic cylinder 41. When the telescopic cylinder 41 is in the self-cleaning state, the pushing protrusion 415 can force the cylinder side wall to open along the fracture line 4113 to form a second drop opening 4115 through the notch 4114 of the telescopic cylinder 41. Therefore, when the rainwater is reflected to the telescopic cylinder 41 by the moving plate 42, the rainwater will carry the solid impurities to drop from the second drop opening 4115 to the drain barrel 6, so as to further improve the self-cleaning effect of the telescopic cylinder 41.

[0094] That is, through the cooperation of the pushing convex strip 415, the telescopic cylinder 41 and the moving plate 42; when the rainwater collecting device cleans the telescopic cylinder 41, the plurality of single-link rings 411 can be opened at the same time to facilitate the solid impurities remaining on each single-link ring 411 to fall off, so as to further improve the self-cleaning effect of the telescopic cylinder 41.

[0095] Embodiment 4

[0096] The difference between this embodiment 4 and embodiment 3 is that:

[0097] With reference to Figure 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 breaking line 4113, the telescopic cylinder 41 further comprises two elastic sealing strips 417, which are arranged on both sides of the breaking line 4113 and are fixedly connected with the single-link ring 411. When the telescopic cylinder 41 is in the working state of filtering rainwater, the two elastic sealing strips 417 are tightly abutted to improve the sealing performance of the single-link ring 411 at the area of the breaking line 4113.

[0098] The elastic sealing strip 417 can be made of elastic materials such as rubber and silica gel. In this embodiment, the elastic sealing strip 417 is made of rubber material, and after the elastic sealing strip 417 is inserted and fixed with the single-link ring 411, the elastic sealing strip 417 and the single-link ring 411 are fixedly connected through hot melt glue.

[0099] Embodiment 5

[0100] The difference between this embodiment 5 and embodiment 3 is that:

[0101] With reference to Figure 14 And Figure 15 The filtering mechanism 3 further comprises a second driving assembly 7, which is fixedly arranged on the side wall of the water storage tank 2. In this embodiment, the telescopic cylinder 41 is rotatably connected with 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 is rotated by the second driving assembly 7, the plurality of single-link rings 411 are synchronously rotated.

[0102] With reference to Figure 14 And Figure 15In the embodiment, the second driving assembly 7 is arranged above the telescopic cylinder 41, and the second driving assembly 7 comprises a motor 71, a gear 72 and a gear ring 73. The motor 71 is fixed to the outer 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. The rotating shaft is fixedly connected with the motor 71, and the gear 72 is fixed to the side of the rotating shaft away from the motor 71. The gear ring 73 is fixed to the outer wall of the telescopic cylinder 41, and the gear ring 73 is engaged with the gear 72, so as to drive the telescopic cylinder 41 to rotate.

[0103] In the embodiment, the motor 71 is a reversible motor 71 (also referred to as a forward and reverse motor 71), which can change the rotating direction instantaneously, from forward rotation to reverse rotation or from reverse rotation to forward rotation. Thus, the second driving assembly 7 can drive the telescopic cylinder 41 to rotate clockwise and counterclockwise reciprocally. For example, the telescopic cylinder 41 rotates clockwise by 10° first, then rotates counterclockwise by 20°, and then rotates clockwise by 20° again, and so on. Thus, the telescopic cylinder 41 is driven to reciprocally swing with small amplitude. When the telescopic cylinder 41 rotates, the solid impurities in the rainwater are forced to move towards the first drop opening 4112 and the second drop opening 4115.

[0104] That is, by alternately operating the first driving assembly 5 and the second driving assembly 7, the filtered solid impurities can be caused to drop into the drainpipe 6 through the first drop opening 4112 and the second drop opening 4115, so as to further improve the self-cleaning effect of the filtering mechanism 3.

[0105] Referring to Figures 15 to 17 The rainwater collecting device further comprises a cleaning mechanism 8, which comprises a cleaning cover 81, a connecting seat 82, a water conveying steel pipe 83, a water conveying hose 84 and a spring member 85. When the telescopic cylinder 41 is compressed to the length of one single 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 moving 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 conveying steel pipe 83 is spherically hinged with the connecting seat 82. One end of the water conveying hose 84 is connected with the water conveying steel pipe 83, and the other end of the water conveying hose 84 is externally connected with a water supply pipeline. After the water is output through the water conveying steel pipe 83, the rainwater jet is to the cleaning cover 81 and the telescopic cylinder 41. One end of the spring member is fixedly connected with the water conveying steel pipe 83, and the other end of the spring member is fixedly connected with the cleaning cover 81. The telescopic cylinder 41 is provided with a spherical protrusion 86, which is used to force the water conveying steel pipe 83 to rotate around the hinge point of the water conveying steel pipe 83.

[0106] Referring to Figure 18In the embodiment, the reflecting plate 43 is provided with a ring groove 432, when the telescopic cylinder 41 is compressed to the length of a single-section ring 411, the filter pipe 1 is inserted into the ring groove 432, and the reflecting plate 43 blocks the filter pipe 1. The water supply hose 84 is connected to the filter pipe 1, and the diameter of the filter pipe 1 is smaller than that of the water supply hose 84, so as to increase the flow rate of the water in the water supply hose 84 and the water supply steel pipe 83, and increase the degree of water flow impacting the telescopic cylinder 41. The filter pipe 1 is inserted into the ring groove 432, so that the reflecting plate 43 blocks the filter pipe 1, and the water in the middle of the filter pipe 1 is jetted through the water supply hose 84 and the water supply steel pipe, so as to use the rainwater jetting telescopic pipe in the filter pipe 1, reduce the installation of external water supply equipment, and save water resources.

[0107] Referring to Figure 17 In the embodiment, along the vertical upward direction, the water-permeable hole 4111 in the single-section ring 411 increases in diameter, so that the high-speed water flow is arranged outside the single-section ring 411 and jetted to the inside of the single-section ring 411.

[0108] The implementation principle of the rainwater collecting equipment for municipal gardens in the embodiment is as follows:

[0109] Referring to Figure 16 and Figure 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, and after the water is jetted through the water supply steel pipe, the water directly impacts the telescopic cylinder 41 or impacts the telescopic cylinder 41 after being reflected by the cleaning cover 81. The water with a large flow rate can impact the telescopic cylinder 41 from the outside of the telescopic cylinder 41 and impact the solid impurities in the water-permeable hole 4111, and the telescopic cylinder 41 is vibrated to shake off the solid impurities on the side wall of the telescopic cylinder 41, so that the solid impurities on the side wall of the telescopic cylinder 41 fall from the first falling port 4112 and the second falling port 4115.

[0110] Meanwhile, when the telescopic cylinder 41 drives the spherical protrusion 86 to rotate, the spherical protrusion 86 forces the water supply steel pipe 83 to rotate around the connecting seat 82, so that the water supply steel pipe 83 can jet water flow in different directions, and the cleaning effect of the cleaning mechanism 8 on the telescopic cylinder 41 is improved.

[0111] When the telescopic cylinder 41 is in a self-cleaning state, the second driving assembly 7 drives the telescopic cylinder 41 to rotate, so that the water flow jetted by the cleaning mechanism 8 can cover more surface area of the telescopic cylinder 41, and the cleaning effect of the cleaning mechanism 8 on the telescopic cylinder 41 is improved.

[0112] It is worth noting that, in order to improve the simplicity of the drawings of the specification, in the embodiment, the water supply steel pipe is provided with one, and in other embodiments, the water supply steel pipe can be provided with multiple, and the multiple water supply steel pipes are directed in different directions.

[0113] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: all equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
