All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Referring to fig. 1, fig. 1 is a schematic perspective view of a collection system of the present application, which may be used to collect rainwater, and may include a collection tank 100 and a filter assembly 200. The filtering assembly 200 is disposed inside the collecting tank 100, and is used for filtering rainwater and conveying the filtered rainwater to the collecting tank 100 for rainwater collection.

The collection tank 100 may have a variety of shapes and may be configured or adjusted according to specific circumstances and conditions. For example, the collecting tank 100 may be configured as a cylindrical cavity, such as a cylinder or a square column, or may be further configured as a polygonal arch structure. The filter assembly 200 may also be installed as a separate unit in the collection tank 100. Such as filter assembly 200, may be positioned within collection tank 100 by lifting or by being placed in a push-in manner.

Referring to fig. 2 and 3, fig. 2 is a schematic top view of the collection system of the present application, and fig. 3 is a schematic cross-sectional view of the collection tank of fig. 2 taken along line a-a. The collecting tank 100 is in a square column shape, and may specifically include a top wall 101, a bottom wall 102, and a side wall 103 connected between the top wall 101 and the bottom wall 102. The top wall 101 is, for example, a side close to the ground when buried underground, and the bottom wall 102 is a side far from the ground when buried underground. The top wall 101, bottom wall 102 and side walls 103 together enclose a collection chamber 104. At least the top wall 101 is arranged in the form of a curved surface among the top wall 101, the bottom wall 102 and the side walls 103, and is arched away from the collecting chamber 104.

Specifically, the top wall 101 is disposed in an arc shape and is arched in a direction away from the collecting chamber 104, and the top wall 101 is arched outward as a whole, and may be formed in an arched structure. Of course, the bottom wall 102 may also be arranged in an arcuate shape, arched away from the collection chamber 104.

In this embodiment, the number of the side walls 103 may be multiple, and at least one of the side walls 103 is also disposed in an arc-surface shape and is arched in a direction away from the collecting cavity 104.

In other embodiments, only the top wall 101 may maintain an arch-shaped configuration, while the side walls 103 and the bottom wall 102 may be planar, concave, or other configurations. In still other embodiments, the top wall 101, the bottom wall 102 and the side wall 103 may be arch-shaped structures, so that the collecting tank 100 can effectively disperse the stress from all directions of the collecting tank 100, thereby enhancing the load-resisting capability thereof, effectively improving the structural stability of the collecting tank 100, and facilitating the industrial production and the forming.

The types of collecting basins 100 may include three types, and the number of the side walls 103 of the collecting basin 100 of the first type may be two, and the two side walls 103 are oppositely arranged, so that the collecting cavity 104 has two openings (not labeled). The number of the side walls 103 of the collecting chamber 100 of the second type may be three, wherein two side walls 103 are oppositely arranged, the other side wall 103 is connected between the two side walls 103, and the collecting chamber 104 has an opening at one side. In order to increase the capacity of the collecting tank 100, a plurality of the first type collecting tanks 100 may be connected in series by abutting the openings. After a plurality of collecting pools 100 of the first type are connected in a butt joint manner, collecting pools 100 of the second type can be connected at two ends respectively to form a complete collecting pool 100. Of course, the open butt joint of two second-type collection pools 100 may also form a complete collection pool 100. The collecting basin 100 of the third type may have four side walls 103, four side walls 103 being connected end to end, and forming a collecting chamber 104 together with the bottom wall 102 and the top wall 101, forming a single collecting basin 100.

The top wall 101, the bottom wall 102 and the side wall 103 of the collecting tank 100 can be detachably connected through assembled flanges and bolts, and the connection stability of the walls can be enhanced. Of course, the walls may be fixed relative to each other by means of snap-fit connection or the like, and for example, in the case of a small-sized collecting tank 100, the side wall 103, the top wall 101, and the bottom wall 102 may be formed by one-shot molding.

The collecting tank 100 arranged in an arch structure improves the bearing capacity of the collecting tank 100, and the risk of collapse of the collecting tank 100 can be greatly reduced.

Referring to fig. 4, fig. 4 is a schematic cross-sectional view of the collecting tank of fig. 2 taken along the section line B-B. The collection tank 100 is made of a steel structure. An inner surface and/or an outer surface of at least one of the top wall 101, the bottom wall 102 and the side wall 103 is provided with a corrugation 1001. For example, the inner and outer surfaces of the top wall 101, side wall 103 and bottom wall 102, respectively, may each be provided with corrugations 1001.

As shown in fig. 4, the corrugated structure 1001 includes a plurality of protrusions 10011 spaced apart along the length of the collection tank 100. The spaced protrusions 10011 may exhibit a wave-like structure. The extending direction of each protrusion 10011 is perpendicular to the length direction.

The corrugated structure 1001 is arranged on the inner surface and/or the outer surface of at least one of the top wall 101, the bottom wall 102 and the side wall 103, so that the structural strength of at least one of the top wall 101, the bottom wall 102 and the side wall 103 can be enhanced, the structural strength of the collecting tank 100 can be further enhanced, stress can be effectively dispersed, and the bearing resistance can be improved.

As for the side walls 103, the extending direction of the protrusions 10011 of the inner surface and the outer surface thereof extends from the top wall 101 to the bottom wall 102, and the protrusions 10011 are spaced apart from each other in the length direction of the collecting tank 100. The protrusions 10011 on the inner surface and the outer surface may be disposed in a staggered manner, and do not overlap, thereby further improving the structural strength of the sidewall 103. Of course, the positions of the protrusions 10011 of the inner and outer surfaces thereof may also be overlapped correspondingly.

As for the top wall 101 or the bottom wall 102, the extending direction of the protrusions 10011 on the inner surface and the outer surface extends from one side wall 103 to the other opposite side wall 103, and the protrusions 10011 are spaced apart from each other in the length direction of the collecting tank 100. The protrusions 10011 on the inner surface and the outer surface thereof may be disposed in a staggered manner without overlapping, thereby further improving the structural strength of the top wall 101 or the bottom wall 102. Of course, the positions of the protrusions 10011 of the inner and outer surfaces thereof may also be overlapped correspondingly.

Specifically, the collection tank 100 may be made of a corrugated steel structure having a corrugated structure 1001. In order to prolong the service life of the corrugated steel structure, the corrugated steel structure can be galvanized steel, and the effects of corrosion prevention and prevention can be achieved. On the basis, the inner surface and/or the inner surface of the collecting tank 100 may be further provided with a protective layer (not shown), such as an epoxy resin ceramic layer, to further improve the acid-base resistance and corrosion resistance.

Of course, at least one of the top wall 101, the side wall 103 and the bottom wall 102 of the collecting tank 100 may be arranged in a wave shape as a whole or in a continuous broken line. The material of the collecting tank 100 is not limited to steel, and may be other materials.

The collecting tank 100 may comprise a service pipe 105, the service pipe 105 is arranged outside the top wall 101, the service pipe 105 communicates with the collecting chamber 104, and the service pipe 105 is capable of guiding rainwater into the collecting chamber 104. The service tube 105 may have water lines, cables, and other related components disposed therein.

Referring to fig. 5 and 6 in combination, the filter assembly 200 includes a water inlet pipe 201, a filter chamber 202, a dirt retention basket 203, and a filter element 204.

The inlet pipe 201 may be fixedly or detachably connected to the top of the filtering chamber 202. I.e. the filtering chamber 202 and the inlet conduit 201, may be integral or separate. The filtering cavity 202 and the water inlet pipe 201 are communicated through a communication port 2023. The dirt-intercepting lifting basket 203 is arranged at the communication port 2023 and is positioned between the water inlet pipe 201 and the filtering cavity 202. Rainwater flows into the water inlet pipe 201, is primarily filtered and intercepted by the sewage intercepting baskets 203, flows into the filtering cavity 202 to be filtered again, and finally flows into the collecting cavity 104 of the collecting tank 100.

The inlet pipe 201 is disposed in the service pipe 105 for receiving external rainwater. For example, one end of the inlet pipe 201 may penetrate out of the service pipe 105 to communicate with an external inlet pipe for receiving rainwater flowing in from the external inlet pipe, or the external inlet pipe may extend into the service pipe 105 to communicate with the inlet pipe 201. The outer inlet pipe may receive rainwater from the ground and direct the rainwater into the inlet pipe 201.

When the collecting tank 100 is in use, the water inlet pipe 201 is generally horizontally placed. A flow discarding port 2011 can be formed in the water inlet pipe 201, and the flow discarding port 2011 is used for discarding rainwater which flows in from the outside and does not meet corresponding conditions. For example, in the case of a small amount of rain, the surface pollutants carried by the rainwater are large, and the water quality is poor, so that the rainwater can be subjected to the flow discarding treatment by using the flow discarding port 2011 without entering the collection chamber 104.

The intake pipe 201 may also include a buoyant ball 2012, a connecting rod 2013, and a shroud 2014. Sunshade 2014 and suspension ball 2012 are connected respectively in the both ends of connecting rod 2013, and the predetermined position of connecting rod 2013 rotatably supports in inlet tube 201 to make it form the thick stick structure, thereby make sunshade 2014 and suspension ball 2012 on the connecting rod 2013 rotate around predetermined position, and then can adjust according to the rainfall in the inlet tube 201 the position of suspension ball 2012 drives sunshade 2014 and shields or open abandon a mouth 2011 that flows.

Specifically, the shape of the shutter 2014 is not limited, and may be any shape as long as the surface thereof is sized to completely block the disposal port 2011. In order to ensure that the floating ball 2012 can be located at different positions when different water amounts are provided, the distance between the preset position and the floating ball 2012 is longer than the distance between the preset position and the shutter 2014, so that the shutter 2014 and the drainage port 2011 can control the storage or drainage of rainwater. For example, when there is no or little rain, the float 2012 touches the bottom of the inlet pipe 201 or floats slightly, and the shutter 2014 is above the discharge opening 2011, so that the discharge opening 2011 is in communication with the inlet pipe 201.

The filter assembly 200 further includes a baffle 2015 disposed downstream of the reject flow port 2011, i.e., between the reject flow port 2011 and the communication port 2023, to space the reject flow port 2011 from the communication port 2023, thereby allowing rainwater to pass between the baffle 2015 and the top of the inlet pipe 201. Because the effect of blockking of baffle 2015 for when the rainwater volume is less, the rainwater is blockked by baffle 2015 and can't continue to flow in and filter cavity 202, and the rainwater volume is less makes suspension ball 2012 effectively float, and then makes abandon a mouthful 2011 and open, and the rainwater is through abandoning a mouthful 2011 outflow. Because the effect of blockking of baffle 2015, when the rainfall amount slowly increases, can make the rainwater of the corresponding volume of long-pending accumulation in inlet tube 201 before filtering cavity 202 to make suspension ball 2012 effectively float, and then make sunshade 2014 can shield abandon and flow mouth 2011, the rainwater passes through between the top of baffle 2015 and the top of inlet tube 201, flows to the pollutant-intercepting hand-basket 203, so can improve quality of water. In this embodiment, the height of the stopper 2015 is not lower than the height of the reject port 2011. For example, the waste outlet 2011 may be square or circular, and the shape of the portion of the baffle 2015 connected to the water inlet pipe 201 may be adapted to the water inlet pipe 201, and the height of the baffle 2015 is greater than or equal to the diameter of the waste outlet 2011, so as to ensure that rainwater can be effectively collected.

Through setting up the suspension ball 2012, sunshade 2014 and connecting rod 2013 constitute lever structure, make the suspension ball 2012 keep the sunshade 2014 not to shelter from abandoning and flow the mouth 2011 when the rainfall volume that gets into inlet tube 201 is less, and then make the relatively poor water of quality flow out and do not collect in collecting the chamber 104 through abandoning to flow the mouth 2011, when getting into inlet tube 201 rainfall volume great, suspension ball 2012 floats, connecting rod 2013 rotates and drives sunshade 2014 and hides shelves and abandons a mouth 2011, and then make water not flow from abandoning a mouth 2011, and then enter into and filter the cavity 202, so can rely on the rainfall volume of rainwater in the inlet tube 201 automatically to adjust the opening or closing of abandoning a mouth 2011, and then can improve the quality of water that gets into and filter cavity 202, carry out further processing, storage collection etc. with the better rainwater of quality effectively, be convenient for recycle.

The filtration chamber 202 is supported between the top wall 101 and the bottom wall 102 of the collection tank 100. When the filter assembly 200 is installed in the collection chamber 104, the inlet pipe 201 extends into the service pipe 105 and the filter chamber body 202 may be supported between the top wall 101 and the bottom wall 102 of the collection tank 100. The filtering cavity 202 may be formed with a mud settling bin 2021 and a filtering bin 2022 which are spaced from each other, and the top of the mud settling bin 2021 in the filtering cavity 202 and the water inlet pipe 201 pass through the communication port 2023. The dirt intercepting basket 203 is disposed at the communication port 2023 to intercept the rainwater flowing into the mud settling bin 2021 through the communication port 2023, wherein the dirt intercepting basket 203 may be a stainless steel basket or another basket, and may be placed and stabilized on the communication port 2023. The dirt-intercepting basket 203 may also be integrally formed to simply filter rainwater flowing from the external inlet pipe and flowing through the communication port 2023.

The bottom of the filter bin 2022 and the bottom of the sludge settling bin 2021 are not isolated and shielded, but are communicated through holes. The top of the filter bin 2022 and the collection chamber 104 are not isolated and shielded, and are communicated through another through hole, so that rainwater flowing in through the bottom of the mud settling bin 2021 flows into the collection chamber 104 from the top of the filter bin 2022.

The filtering member 204 is disposed in the filtering bin 2022 to filter the rainwater filtered by the sludge deposited in the sludge depositing bin 2021 again, so that the filtered rainwater flows into the collecting chamber 104 from the top of the filtering bin 2022. The filter element 204 may include activated carbon, a biocide, or the like.

In some embodiments, one end of the filtering chamber 202 may be fixedly connected to the inner surface side of the top wall 101 of the collecting tank 100, and the other end of the filtering chamber 202 may not directly abut against the bottom wall 102. Of course, the inlet pipe 201 extends into the service pipe 105, and the filtering chamber 202 may not directly contact the top wall 101 of the collecting tank 100.

In some embodiments, the filter assembly 200 may further include a sludge pump 205, and the sludge pump 205 is located at the bottom of the sludge settling bin 2021 and is configured to discharge some substances, such as the sludge filtered by the dirt-intercepting basket 203 and flowing into the sludge settling bin 2021 for settling. Rainwater enters the mud settling bin 2021 from the water inlet pipe 201 and the dirt intercepting and lifting basket 203, soil and other substances can be deposited at the bottom of the mud settling bin 2021 due to the gravity, and the rainwater can flow from the bottom of the filter bin 2022 to the top of the filter bin 2022 through the filter element 204 for further filtering. In some embodiments, the rainwater can be preliminarily filtered in the external water inlet pipe, for example, the sewage interception grating is arranged at the pipe orifice of the external water inlet pipe, and large impurities are filtered.

Through the filtering treatment of the filtering assembly 200, relatively clean rainwater obtained after the filtering assembly 200 is treated is collected and recycled.

This application sets up the collecting pit 100 that has strong anti bearing capacity's domes and has filtration treatment's filter assembly 200 layer upon layer, under the effect that can improve compressive capacity and water purification treatment, improves compressive capacity, extension practical life.

Specifically, the workflow of the collection system of the present application may be as follows:

at the beginning, the rainwater is less, and the water level is lower, and the rainwater flows into outside inlet tube from the rainwater mouth, gets into inlet tube 201, and collecting system directly abandons this rainwater from abandoning class mouth 2011 and flows, washes away surperficial spot, does not get into collecting pit 100 this moment.

Along with the rainfall increases, the water level is higher, the buoyancy of rainwater impels suspension ball 2012 to float, it is corresponding, sunshade 2014 will abandon downwards and flow mouth 2011 seals, so that the water yield accumulation increases, when the rainwater surpasses the height of baffle 2015, will bypass baffle 2015 and get into and cut dirty hand-basket 203, cut dirty the filtration through cutting dirty hand-basket 203 to the rainwater, later get into heavy mud storehouse 2021 in, utilize the effect of gravity, deposit some heavy mud grit, utilize the principle of gravity flow and adverse current to change into the water flow direction simultaneously, make later rainwater get into filtration piece 204 in the filter silo 2022 from heavy mud storehouse 2021 bottom and carry out filtration processing, along with it, get into collecting pit 100 from the through-hole at its top, collect the rainwater after filtering at regular intervals, mud pump 205 or the automatic mud discharging of response are in order to be used many times.

At the in-process that the rainwater constantly increases, the rainwater in the collecting pit 100 stores up fully, therefore unnecessary rainwater will not get into collection system, and can get into municipal pipe network through reposition of redundant personnel well etc. and discharge water from municipal pipe network, guarantee drainage safety.

The above description is only for the purpose of illustrating embodiments of the present application and is not intended to limit the scope of the present application, and all modifications of equivalent structures and equivalent processes, which are made by the contents of the specification and the drawings of the present application or are directly or indirectly applied to other related technical fields, are also included in the scope of the present application.
