Description

Technical Field

[0001] The invention relates to the field of rainwater circulation, and more specifically to a rainwater circulation structure for a city park. Background Art

[0002] With the acceleration of urbanization, a large amount of hardened ground (such as cement and asphalt pavement) increases the runoff of rainwater and reduces the natural infiltration of rainwater, resulting in a large amount of rainwater runoff during heavy rains, causing urban waterlogging. Therefore, in order to improve the sustainable development of cities, reduce urban waterlogging during heavy rains, and reduce excessive exploitation of groundwater, rainwater recycling equipment is usually added to urban parks to collect, store and reuse rainwater. However, in existing rainwater circulation equipment, the diameter of the pipes used to collect and transport rainwater is mostly constant, and the diameter of the pipe cannot be adjusted according to the amount of rainfall. When using such pipes with a constant diameter, the following problems will occur: if the pipe diameter is large and the rainfall is small, the rainwater will flow slowly in the pipe, increasing the probability of impurities in the rainwater settling at the bottom of the pipe, which easily increases the risk of pipe blockage; if the pipe diameter is small and the rainfall is large, the pipe cannot transport and collect rainwater in time, reducing the timeliness of the equipment's rainwater collection.

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0021] See also Figures 1 to 18 A rainwater circulation structure for an urban park includes a road 1, a waste flow pool 2, a filter box 3, and a water storage tank 5. A pipe body 4 is fixedly connected between the waste flow pool 2 and the filter box 3. A filter component 7 is arranged in the waste flow pool 2. A rotating shaft 8 is sealed and rotatably installed on the waste flow pool 2. A driving component 9 is arranged on the rotating shaft 8. An adjusting component 10 is arranged in the pipe body 4. A speed-up component 12 is commonly arranged between the filter box 3 and the pipe body 4.

[0022] Before the waste flow pool 2, the filter box 3, the water storage tank 5 including the overflow pool 131 need to be buried inside the road 1, firstly, a suitable pit is dug on the road 1 by using the existing excavation facilities, and then the excavated pit is reinforced and fixed by using concrete or sand and gravel, and then the waste flow pool 2, the filter box 3, the water storage tank 5 including the overflow pool 131 are placed as needed, and the waste flow pool 2, the filter box 3, the water storage tank 5 and the overflow pool 131 are fixed in position by means of anchor bolts, etc., so as to effectively prevent them from being displaced during the placement process.

[0023] like Figure 1 - Figure 8 As shown, the filter assembly 7 includes a rainwater grate 71 snap-fitted and installed on the upper end of the waste flow pool 2, a drain outlet 714 is provided on the waste flow pool 2, two drain outlets 714 are provided, and linearly evenly distributed rotating rods 710 are rotatably installed on the two drain outlets 714, and filter plates 711 are fixedly installed on the rotating rods 710, and a pushing mechanism is installed in the waste flow pool 2.

[0024] The pushing mechanism includes a placement cavity 715 opened on the discarded flow pool 2, and there are two placement cavities 715. The upper end of the rotating rod 710 is sealed and passes through the discarded flow pool 2 and extends into the corresponding placement cavity 715. A slide groove 716 is opened in the discarded flow pool 2. There are two slide grooves 716, and the two slide grooves 716 are connected to the corresponding placement cavity 715. A push plate 712 is fixedly installed on the rotating rod 710. Threaded rods 78 are rotatably installed in the two placement cavities 715. Linearly evenly distributed pushing members 713 are threadedly installed on the two threaded rods 78. A lifting component is installed between the two threaded rods 78 and the discarded flow pool 2.

[0025] The lifting component includes a plurality of limit rods 73 fixedly mounted on the inner wall of the abandoned flow pool 2, a floating plate 1 74 is fixedly mounted between the two lower limit rods 73, and a floating plate 2 75 is fixedly mounted between the two upper limit rods 73 (the upper and lower parts are referred to as the upper and lower parts). Figure 5 , Figure 5 The position of the limit rod 73 marked on the middle kettle body is at the bottom, and the position of the floating plate 2 75 is at the top), and one end of the floating plate 1 74 and the floating plate 2 75 are slidably installed on the corresponding slide groove 716, and the floating plate 1 74 and the floating plate 2 75 are fixedly installed with a rack rod 77, and the two threaded rods 78 are fixedly installed with an incomplete gear 79 that matches the corresponding rack rod 77, and a limit plate 76 is fixedly installed on the inner wall of the abandoned flow pool 2, and two limit plates 76 are provided.

[0026] The driving assembly 9 includes a sewage intercepting basket 72 fixedly installed in the waste flow pool 2, a spring member 94 is fixedly installed on the bottom wall of the waste flow pool 2, a spring member 95 is fixedly installed on the lower end of the sewage intercepting basket 72, a cleaning scraper 96 is fixedly installed on both the spring member 1 94 and the spring member 2 95, an eccentric wheel 93 is fixedly installed on the rotating shaft 8, a water wheel 92 is fixedly installed on the rotating shaft 8, and a drainage plate 91 is fixedly installed between the sewage intercepting basket 72 and the waste flow pool 2.

[0027] from Figure 4 It can be seen in the figure that the left end of the tube body 4 is directly opposite to the lower drain port 714 , and the left end of the connecting tube 132 is directly opposite to the upper drain port 714 .

[0028] like Figure 5 In the direction shown, in the initial state, the upper and lower multiple water filter plates 711 are in a state of contact with each other. At this time, through the cooperation of the lower multiple water filter plates 711, the lower drain outlet 714 of the abandoned flow pool 2, that is, the left end of the pipe body 4, can be blocked. At the same time, through the cooperation of the upper multiple water filter plates 711, the upper drain outlet 714, that is, the left end of the connecting pipe 132 can be blocked (as shown in FIG. Figure 4In the direction shown), this can help prevent dust, leaves, garbage and other impurities in the air, as well as animals such as mice and snakes from entering the pipe body 4 or the connecting pipe 132 when the pipe body 4 and the connecting pipe 132 are not needed for collecting and transporting rainwater, causing blockage and corrosion inside the pipe body 4 or the connecting pipe 132, thereby reducing the speed and effect of the subsequent pipe body 4 or the connecting pipe 132 for collecting and transporting rainwater.

[0029] When the rainwater collected on the road 1 flows into the waste flow pool 2, the rainwater grate 71 can intercept larger impurities such as branches and plastic bags in the rainwater, and the sewage interception basket 72 can further intercept smaller impurities such as stones and fallen leaves in the rainwater, thereby achieving the effect of preliminary filtration of the rainwater.

[0030] If impurities such as stones and fallen leaves enter the pipe body 4, that is, the annular channel formed by multiple positioning plates 102 and elastic plates 103, or the connecting pipe 132 under the influence of water flow, these impurities may easily clog the inside or wear the inner wall, which not only easily reduces the subsequent rainwater collection speed of the equipment, but also reduces the service life of the annular channel and the connecting pipe 132.

[0031] The purpose of disposing the drain outlet 714 at the lower middle end of the abandoned flow pool 2 is (as Figure 4 In the direction shown), since in the initial stage of rainfall, rainwater will wash the roof, road surface, etc., and bring pollutants (such as dust, mud, oil, heavy metals, etc.) on the surface of the roof, road surface, etc. into the waste flow pool 2, these pollutants are easy to wear and corrode the annular channel and the inside of the connecting pipe 132. Therefore, the lower drain outlet 714 is set at the middle and lower end of the waste flow pool 2, which can facilitate the rainwater that initially enters the waste flow pool 2 to be collected at the lower end of the waste flow pool 2, so as to achieve the effect of the equipment discarding the initial rainwater. This not only improves the water quality of the rainwater collected by the equipment, but also further realizes the protection of the annular channel and the connecting pipe 132.

[0032] After the equipment collects rainwater, people can remove the rainwater grate 71 above the waste flow pool 2 and regularly clean the impurities filtered and collected on the sewage interception basket 72 to ensure the subsequent filtering speed and effect of the rainwater by the sewage interception basket 72. At the same time, a detachable connection method is adopted between the rainwater grate 71 and the waste flow pool 2. The purpose is to facilitate people to regularly clean the impurities above the sewage interception basket 72 and then remove it. Then, use the existing sewage pumping equipment to clean the impurities collected on the bottom of the waste flow pool 2, which helps to ensure the subsequent waste flow effect of the waste flow pool 2 on the initial rainfall.

[0033] When the amount of rainwater collected in the wastewater pool 2 increases continuously, the buoyancy of the rainwater on the floating plate 74 pushes the floating plate 74 and the rack rod 77 corresponding to the floating plate 74 to continuously move upward (such as Figure 5In the direction shown), at this time, the rack rod 77 and the corresponding incomplete gear 79 cooperate to drive the lower threaded rod 78 to rotate (as shown in FIG. Figure 5 direction shown).

[0034] At this time, the rotation of the lower threaded rod 78 will drive the corresponding plurality of pushers 713 to move to the left (such as Figure 6 When the plurality of push members 713 move to the left, the thrust generated on the corresponding push plate 712 will drive the corresponding rotating rod 710 to drive the corresponding water filter plate 711 to rotate clockwise (as shown in FIG. Figure 6 As shown in the direction), until the upper end of the floating plate 74 contacts the lower end of the corresponding limit plate 76, the plurality of water filter plates 711 rotate to a vertical state (combined with Figure 5 and Figure 6 In the direction shown), the rainwater collected in the waste flow pool 2 will flow into the annular channel through the gap between two adjacent water filter plates 711.

[0035] from Figure 6 It can be seen that after rotating vertically, the distance between two adjacent water filter plates 711 is shorter. Therefore, through the gap between the two adjacent water filter plates 711, smaller particulate impurities in the rainwater can be filtered, thereby further improving the cleanliness of rainwater entering the annular channel or the connecting pipe 132, further reducing the blockage and wear of the annular channel or the connecting pipe 132 by rainwater, and helping to further improve the quality of rainwater collected by the equipment.

[0036] Similarly, when the amount of rainwater in the abandoned flow pool 2 increases, the buoyancy of the rainwater on the floating plate 2 75 pushes it upward (such as Figure 5 As shown in the direction, the cooperation of the second floating plate 75 with the corresponding rack rod 77, the incomplete gear 79 and the threaded rod 78 can cause the multiple water filter plates 711 above to rotate under force, and the gap between two adjacent water filter plates 711 is continuously increased, thereby achieving the filtering effect of smaller impurities in the rainwater entering the connecting pipe 132, and improving the cleanliness of the rainwater entering the connecting pipe 132.

[0037] Combination Figure 5 and Figure 6 It can be seen that in the initial state, the two cleaning scrapers 96 are located at the lower end of the corresponding water filter plate 711, and the scraping teeth on the cleaning scraper 96 are adapted to the gap between the corresponding two water filter plates 711 after rotating to the vertical state. The purpose is to facilitate the subsequent scraping and cleaning of impurities intercepted and filtered in the gap between the corresponding two water filter plates 711 when the cleaning scraper 96 is forced to move up and down.

[0038] After the rainwater is initially filtered by the sewage interception hanging basket 72, the rainwater moves downward under its own gravity, and part of the rainwater is drained by the drainage plate 91 and collected above the water wheel 92 (such as Figure 8 As shown in the direction, the impact force generated by the rain in the falling process will prompt the water wheel 92 to drive the rotating shaft 8 and the eccentric wheel 93 to rotate together. Since the spring member 94 is in a compressed state in the initial state, when the eccentric wheel 93 rotates upward intermittently, the pressure on the spring member 94 gradually disappears. At this time, the spring member 94 will drive the corresponding cleaning scraper 96 to move upward under the action of its own elastic force (as shown in the direction shown in the direction). Figure 8 As shown in the direction, when the eccentric wheel 93 rotates downward intermittently, it presses the spring member 94 to drive the corresponding cleaning scraper 96 to move downward continuously, so that the cleaning scraper 96 can intermittently move up and down, and the impurities intercepted in the gaps between the corresponding multiple water filter plates 711 can be scraped and cleaned, thereby ensuring the speed and effect of the multiple water filter plates 711 to continuously intercept impurities in rainwater.

[0039] Similarly, when the amount of rainwater collected in the wastewater pool 2 is large, the multiple water filter plates 711 above also rotate to a vertical state (such as Figure 5 In the direction shown), the eccentric wheel 93 rotates up and down intermittently, and the intermittent compression and release of the spring member 95 drive the upper cleaning scraper 96 to move up and down intermittently, scraping off the impurities intercepted by the corresponding multiple water filter plates 711, ensuring the cleanliness of the rainwater entering the connecting pipe 132 when the amount of rainwater in the waste flow pool 2 is large.

[0040] At the same time, since the rotation speed of the water wheel 92 driving the rotating shaft 8 and the eccentric wheel 93 is related to the amount of rainfall, when the rainfall is small, the impact force of rainwater on the water wheel 92 is small, and the eccentric wheel 93 drives the two cleaning scrapers 96 to move intermittently up and down at a relatively slow speed (such as Figure 8 In the direction shown), on the contrary, when the rainfall is heavy, the rain drives the water wheel 92 to drive the rotating shaft 8 to rotate quickly, which can effectively speed up the intermittent up and down reciprocating movement of the two cleaning scrapers 96, thereby improving the speed at which the two cooperate with the corresponding multiple water filter plates 711 to scrape and clean the impurities.

[0041] like Figure 5 , Fig. 9 - Fig.12 , Fig.18 As shown, the adjustment component 10 includes an elastic sealing plate 101 fixedly installed in the tube body 4, two elastic sealing plates 101 are provided, and a positioning plate 102 evenly distributed in a ring shape is fixedly installed between the two elastic sealing plates 101, and an elastic plate 103 evenly distributed in a ring shape is fixedly installed between the two elastic sealing plates 101, and the elastic plates 103 are fixedly connected to the corresponding positioning plates 102, and a driving cylinder 106 is slidably installed on the tube body 4, two driving cylinders 106 are provided, a limiting component is installed between the two driving cylinders 106, and a knocking component is installed between the two driving cylinders 106.

[0042] The limiting components include annular grooves 108 respectively opened in the two driving cylinders 106, and sliding rods are slidably installed on the two annular grooves 108, and there are two sliding rods. A fixed cylinder 107 is fixedly installed between the corresponding two sliding rods, and limiting blocks 109 evenly distributed in an annular shape are fixedly installed in the two fixed cylinders 107. A plurality of return springs 105 are fixedly installed on the tube body 4, and blocks 104 are fixedly installed on the positioning plate 102, and there are two blocks 104, and the blocks 104 are fixedly connected to the corresponding return springs 105.

[0043] When the multiple water filter plates 711 below cooperate to filter the rainwater (such as Figure 5 As shown in the direction, rainwater flows into the right end of the pipe body 4 (as shown in the direction shown in the figure) along the annular channel formed by the cooperation of multiple positioning plates 102 and multiple elastic plates 103. Fig. 9 The water flows in the filter box 3 and finally collects in the filter box 3. The filter (from Figure 3 It can be seen that a filter is provided inside the filter box 3 for further filtering rainwater, which will further filter the rainwater. After the treatment, the rainwater will be collected in the water storage tank 5 along the one-way water supply pipe 134.

[0044] like Fig.10 As shown, in the initial state, the plurality of limit blocks 109 limit the position of the corresponding block 104. At this time, the plurality of return springs 105 are in a compressed state, and the diameter of the annular channel formed by the plurality of positioning plates 102 and the plurality of elastic plates 103 is relatively small.

[0045] When the rainfall is small, using two adjacent water filter plates 711 to filter smaller impurities in the rainwater can not only improve the cleanliness of the rainwater entering the annular channel, but also because the diameter of the annular channel is smaller at this time, it can effectively speed up the flow rate of the rainwater after entering the annular channel, thereby effectively reducing the possibility of impurities in the rainwater being precipitated inside the annular channel.

[0046] When the rainfall is small, the flow speed of rainwater in the annular channel under the low flow rate state is relatively slow, so the particulate impurities in the rainwater have enough time to settle inside the annular channel, and when the rainwater flow speed is relatively slow, the scouring force of rainwater on the impurities that have been settled is relatively small, so the impurities settled inside the annular channel will continue to increase, and with the increase of impurities settled at the bottom of the annular channel, the effective water flow area of ​​the annular channel will gradually decrease, so the slower water flow speed can easily cause blockage inside the annular channel, reducing the speed of the annular channel for collecting and transporting rainwater, and because the annular channel is arranged inside the pipe body 4, and the pipe body 4 is located inside the road 1, it is difficult to manually clean the inside of the pipe body 4, and the impurities settled inside the annular channel can easily corrode the inside of the annular channel for a long time, reducing its service life.

[0047] like Fig. 9 - Fig.15 As shown, the knocking component includes a plurality of spring telescopic rods 1012 fixedly mounted on the tube body 4, each of which is fixedly mounted with a knocking rod 1013, and each of the knocking rods 1013 penetrates and is slidably mounted on the tube body 4, and each of the upper ends of the knocking rods 1013 is rotatably mounted with a roller 1014, and each of the two driving cylinders 106 is fixedly mounted with a protrusion 1010 evenly distributed in a ring shape, and each of the two driving cylinders 106 is fixedly mounted with a protrusion 2 1011 evenly distributed in a ring shape.

[0048] A transmission assembly 11 is provided on the rotating shaft 8, and the transmission assembly 11 includes a round roller 1101 fixedly mounted on the rotating shaft 8. There are two round rollers 1101, and the two round rollers 1101 are fixedly mounted with fixed rods 1102 evenly distributed in a ring shape. Round rods 1103 are penetrated and slidably mounted on the fixed rods 1102, and roller 2 1108 is rotatably mounted on one end of the round rods 1103. A driving wheel 1104 is slidably mounted on the rotating shaft 8. There are two driving wheels 1104, and the two driving wheels 1104 are fixedly connected to the corresponding round rods 1103, and a sliding component is commonly installed between the two round rollers 1101.

[0049] The sliding component includes fixed grooves 1105 which are evenly arranged in annular shapes on two round rollers 1101, and spring telescopic rods 1106 are fixedly installed on the fixed grooves 1105. A push block 1107 that matches the corresponding roller 1108 is fixedly installed on one end of the spring telescopic rods 1106.

[0050] Friction rings (such as Fig.14 The purpose is to increase the friction between the two driving wheels 1104 and the corresponding driving cylinders 106 through the cooperation of two adjacent friction rings, so as to ensure that when the driving wheel 1104 is rotated under force, the corresponding driving cylinder 106 is driven to rotate together.

[0051] When the rain drives the rotating shaft 8 to rotate, the two round rollers 1101 cooperate with the multiple fixed rods 1102 and the multiple round rods 1103 to drive the two driving wheels 1104 to rotate together with the rotating shaft 8. When the two driving wheels 1104 rotate, the friction between the middle position of the two driving wheels 1104 and the corresponding driving cylinders 106 will drive the two driving cylinders 106 to drive the multiple protrusions 1010 and the multiple protrusions 1011 inside thereof to rotate together with the corresponding driving wheels 1104. When the multiple protrusions 1010 intermittently rotate to the top of the roller 1014 (combined with Fig.12 and Fig.13 It can be seen that in the initial state, the plurality of rollers 1014 are directly opposite to the corresponding protrusions 1010. The extrusion force exerted by the protrusions 1010 on the rollers 1014 will drive the corresponding knocking rods 1013 of the rollers 1014 to approach the outer wall of the corresponding elastic plate 103 (such as Fig.12 In the direction shown), tapping the surface of the corresponding elastic plate 103; The vibration force generated by hitting the outer wall of the elastic plate 103 will be transmitted to the rainwater inside the annular channel through the elastic plate 103, causing the water surface to fluctuate. This fluctuation will change the interaction force between water molecules, breaking the original equilibrium state and reducing the friction resistance of the elastic plate 103 and the inner wall of the positioning plate 102 to the flow of rainwater (such as Fig.12 The continuous vibration can overcome the viscous resistance of the water body to a certain extent, thereby further accelerating the flow speed of rainwater inside the annular channel. It can not only further reduce the probability of impurities in the rainwater settling inside the annular channel, but also, to a certain extent, speed up the equipment's collection of rainwater.

[0052] When the driving cylinder 106 drives the multiple protrusions 1010 to rotate away from the corresponding rollers 1014 and the extrusion force applied to the multiple knocking rods 1013 disappears, the knocking rods 1013 will drive the corresponding rollers 1014 to move and reset under the action of the elastic force of the spring telescopic rod 1012 until the rollers 1014 fit against the inner walls of the corresponding driving cylinder 106. Through the above operation, the effect of the multiple knocking rods 1013 intermittently knocking on the corresponding elastic plates 103 can be achieved.

[0053] If the rainfall is heavy (such as heavy rain), the amount of rainwater entering the waste flow pool 2 and the flow speed of the rainwater increase significantly. The rotation speed of the rainwater-driven shaft 8 will also increase accordingly. When the shaft 8 rotates rapidly and generates centrifugal force, the multiple spring telescopic rods 1106 will overcome their own elastic force, so that the push blocks 1107 on the multiple spring telescopic rods 1106 will expand to the surroundings under the action of centrifugal force.

[0054] When the plurality of push blocks 1107 are displaced in all directions, a pushing force to the right is generated on the corresponding roller 1014 (eg Fig.14 As shown in the direction, the plurality of rollers 1014 and the plurality of round rods 1103 will cooperate to push the corresponding driving wheel 1104 to move to the right side. When the driving wheel 1104 moves to the right side, the thrust generated by the left end of the driving wheel 1104 on the corresponding driving cylinder 106 will cause the driving cylinder 106 to drive the corresponding fixed cylinder 107 to move to the right side together with the driving wheel 1104. When the fixed cylinder 107 drives the plurality of limit blocks 109 inside thereof to move to the right (eg Fig.11 In the direction shown), when the pressing force on the corresponding block 104 gradually weakens, under the action of the corresponding two reset springs 105's own elastic force, the multiple blocks 104 will cooperate to drive the multiple positioning plates 102 to move away from each other. In the process of the multiple positioning plates 102 moving away from each other, the corresponding elastic plates 103 will be stretched, and the two elastic sealing plates 101 will be compressed, so as to increase the diameter of the annular channel formed by the multiple positioning plates 102 and the multiple elastic plates 103, which helps to increase the rainwater holding capacity of the annular channel, increase the rainwater collection capacity of the annular channel, and ensure the rainwater collection speed of the equipment when the rainfall is heavy.

[0055] At the same time, when the driving cylinder 106 is forced to move to the right (such as Fig.11 In the direction shown), the multiple protrusions 1010 will gradually move away from the corresponding roller 1014 until the multiple protrusions 1011 move to be opposite to the corresponding roller 1014, thereby ensuring that the compressed moving distance of the multiple knocking rods 1013 is adapted to the elastic plate 103 after unfolding. When the driving cylinder 106 rotates, the multiple protrusions 1011 cooperate with the multiple rollers 1014 to drive the multiple knocking rods 1013 to intermittently knock on the outer wall of the corresponding elastic plate 103. Since the rotation speed of the two driving cylinders 106 of the rotating shaft 8 is faster at this time, the cooperation between the multiple protrusions 1011 and the multiple knocking rods 1013 will speed up the knocking speed on the outer wall of the multiple elastic plates 103, thereby ensuring the collection speed of rainwater in the annular channel when the diameter of the annular channel is increased and the amount of rainwater collected is increased.

[0056] like Fig.16 - Fig.18 As shown, the speed-up assembly 12 includes a drainage box 121 fixedly mounted on the side wall of the filter box 3, and a cavity (drawn but not marked in the figure) is opened on the drainage box 121. Fig.17 As can be seen in the figure, the tube body 4 is fixedly connected with a suction pipe 123, and one end of the suction pipe 123 is sealed and penetrates the drainage box 121 and extends into the cavity, and the filter box 3 is fixedly connected with a water pipe 127, and one end of the water pipe 127 is sealed and penetrates the drainage box 121 and extends into the cavity; A transmission rod 124 is rotatably mounted on the cavity, and one end of the transmission rod 124 is sealed and penetrates and is rotatably mounted on the drainage box 121. A sprocket is fixedly mounted on the transmission rod 124 and the rotating shaft 8 (the figure is drawn but not marked, from Fig.16 As can be seen in the figure, a chain 122 is installed between the two sprockets, a rotating gear 125 is fixedly installed on the transmission rod 124, and a gear rod 126 meshing with the rotating gear 125 is rotatably installed on the cavity.

[0057] When the rainfall is heavy and the shaft 8 rotates quickly, the two sprockets and the chain 122 cooperate to make the transmission rod 124 drive the rotating gear 125 to rotate counterclockwise around the transmission rod 124. Since the teeth on the rotating gear 125 and the gear rod 126 are opposite, the gear rod 126 rotates clockwise (e.g. Fig.17 direction shown).

[0058] When the rotating gear 125 rotates counterclockwise (such as Fig.17 The gear rod 126 is driven to rotate in the opposite direction, and the gear 125 is gradually disengaged from the tooth block at the right end of the gear rod 126. When the volume between the teeth continues to increase, a local vacuum is formed between the tooth blocks. At this time, according to Pascal's law, the liquid flowing into the tube body 4 can be continuously sucked into the cavity through the straw 123. This process is like a miniature "vacuum pump" at work, which continuously sucks rainwater from the tube body 4 into the cavity.

[0059] At the same time, the rotating gear 125 and the gear rod 126 continue to rotate in coordination, and the gear blocks at the left ends of the two gradually mesh (such as Fig.17 In the direction shown), the volume between the teeth will gradually decrease, and the liquid between the teeth will eventually be compressed and discharged into the water pipe 127, and enter the filter box 3 along the water pipe 127. At the same time, when the adjacent tooth blocks are constantly meshing and approaching, the liquid between the teeth is strongly squeezed. This continuous squeezing will exert a continuous forward thrust on the liquid, thereby pushing the liquid inside the cavity and accelerating it into the water pipe 127. In this way, the speed at which the liquid inside the tube body 4 enters the filter box 3 can be accelerated, and the flow speed of rainwater in the annular channel can be further increased, thereby improving the rainwater collection speed of the equipment when the rainfall is large.

[0060] like Fig.18As shown, an overflow assembly 13 is provided between the waste pool 2 and the filter box 3, and the overflow assembly 13 includes a connecting pipe 132 fixedly connected to the waste pool 2, a drainage pipe 133 fixedly connected to the filter box 3, an overflow pool 131 fixedly connected between the connecting pipe 132 and the drainage pipe 133, a one-way water supply pipe 1 134 fixedly connected between the filter box 3 and the water storage tank 5, a one-way water supply pipe 2 135 fixedly connected between the filter box 3 and the water storage tank 5, and a suction pipe 6 is sealed, penetrated and fixedly installed on the water storage tank 5 (the rainwater collected in the water storage tank 5 can eventually be discharged through the suction pipe 6 in cooperation with the existing pumping equipment).

[0061] When the rainfall is large, if the speed of rainwater transported by the annular channel formed by the plurality of positioning plates 102 and the plurality of elastic plates 103 is lower than the speed of rainwater entering the waste pool 2, the amount of rainwater inside the waste pool 2 increases, and the water level inside the waste pool 2 exceeds the lower end of the upper drain outlet 714 (such as Figure 4 In the direction shown), part of the rainwater in the waste pool 2 will flow along the connecting pipe 132 into the overflow pool 131 for buffering, which can help reduce the risk of overflow of the rainwater collected in the waste pool 2 during heavy rainfall, causing waterlogging in the park road 1.

[0062] At the same time, if the rainfall is heavy, the amount and speed of rainwater entering the filter box 3 will continue to increase. When the amount of rainwater inside the filter box 3 continues to increase, the one-way water supply pipe 135 can be used to accelerate the speed at which the rainwater inside the filter box 3 enters the water storage tank 5, thereby effectively ensuring the collection speed of the rainwater transported by the filter box 3 to the annular channel.

[0063] Usage: When it rains, rainwater on the road 1 in the park will be initially filtered by the rainwater grate 71 and the sewage interception hanging basket 72, and then enter the waste flow pool 2. When the rainwater in the waste flow pool 2 increases, the rainwater will push the floating plate 74 upward (such as Figure 5 In the direction shown), during the upward movement of the floating plate 74, through cooperation with the lifting component, the multiple water filter plates 711 below the displacement waste flow pool 2 can be driven to rotate and unfold. At this time, through the cooperation of the multiple unfolded water filter plates 711, smaller particle impurities in the rainwater can be filtered, thereby effectively improving the cleanliness of the rainwater entering the pipe body 4.

[0064] At the same time, as the drainage plate 91 drains the rainwater, part of the rainwater will drive the water wheel 92 to rotate. When the water wheel 92 rotates, through the cooperation of the rotating shaft 8, the eccentric wheel 93 and the spring member 94, it will drive the cleaning scraper 96 below to move up and down intermittently, so as to scrape and clean the impurities stuck in the gap between the corresponding two water filter plates 711.

[0065] When the amount of rainwater is small and the rotation speed of the rotating shaft 8 is slow, the rainwater will directly enter the annular channel formed by the cooperation of multiple positioning plates 102 and multiple elastic plates 103, and enter the filter box 3 along the annular channel and the tube body 4. At the same time, in this process, through the cooperation of the knocking component of the rotating shaft 8, the multiple knocking rods 1013 can intermittently knock on the corresponding elastic plates 103. The vibration force generated during the knocking process helps to accelerate the flow speed of rainwater inside the multiple positioning plates 102 and the multiple elastic plates 103, thereby effectively reducing the occurrence of rainwater precipitation inside the annular channel.

[0066] If the rainfall is heavy and the rotation speed of the shaft 8 is fast, the cooperation between the shaft 8, the transmission component 11 and the limit component can drive the multiple positioning plates 102 to move away from each other and expand, thereby increasing the capacity of the annular channel for rainwater. At the same time, in this process, through the cooperation between the shaft 8 and the speed-up component 12, the water delivery speed of the pipe body 4 and the annular channel to the inside of the filter box 3 can be accelerated, thereby effectively improving the speed of the equipment to collect rainwater, and when the rainfall increases, the overflow component 13 can be used to cache the excess rainwater entering the waste flow pool 2.

[0067] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
