Technical Field

[0001] The present application relates to the field of rainwater collection, and in particular, to a rainwater collection and reuse system. Background Art

[0002] With the acceleration of urbanization, the use of rainwater as a key element in the water cycle system plays an important role in building a sustainable urban water cycle system;

[0003] For example, patent number (CN205935040) discloses a rainwater collection system, which includes a rainwater collection trough, a rainwater collection trough cover, a filter, and a rainwater collection well. There are several rainwater collection wells evenly arranged on the roadside, and a well cover is provided on the rainwater collection well. The rainwater collection wells are connected through the rainwater collection trough, and a rainwater collection trough cover is provided at the upper end of the rainwater collection trough. A filter is provided at the connection between the rainwater collection trough and the rainwater collection well. Rainwater falls into the rainwater collection trough, is filtered by the filter, and is stored in the rainwater collection well, so as to achieve rapid collection of rainwater.

[0004] However, in the disclosed solution, a large amount of debris will inevitably adhere to the filter during long-term use, thereby affecting the filtration and collection efficiency of rainwater;

[0005] There is currently no rainwater harvesting and reuse system on the market that can fully utilize filters. Summary of the Invention

[0006] The content of this application is used to briefly introduce concepts that will be described in detail in the detailed description section below. The content of this application is not intended to identify key features or essential features of the technical solution for which protection is sought, nor is it intended to limit the scope of the technical solution for which protection is sought.

[0007] In order to solve the technical problems mentioned in the above background technology section, some embodiments of the present application provide a rainwater collection and reuse system, wherein the housing forms a collection chamber for collecting rainwater;

[0008] The sealing shell is fixed inside the collecting chamber to form a sealed chamber for filtering rainwater;

[0009] A connecting pipe connecting the collecting chamber and the sealing chamber;

[0010] A water pipe, connecting the sealed cavity and the outside, for draining water from the sealed cavity;

[0011] The water pump is installed at the bottom of the collection chamber to provide power for the rainwater to flow in the connecting pipe to the sealed chamber;

[0012] A disinfector is arranged at the inner top of the sealed cavity;

[0013] A plurality of filter screens are arranged in the sealed cavity;

[0014] A support member is provided at the bottom of the sealing cavity and is used to support a plurality of filter screens;

[0015] The connecting pipe passes through the support member to the top of the support member, and the connecting pipe located above the support member forms a water outlet;

[0016] The support member is composed of a plurality of support surfaces for installing the filter screen and side surfaces connecting two adjacent support surfaces; the support surfaces are distributed in a stepped manner from bottom to top, so that the support member is in a tower shape; and a cavity is formed inside the support member;

[0017] Among them, a rotating ring is arranged on the side, which is used to install and drive the filter to rotate;

[0018] Through the above scheme, rainwater can be filtered through the rotating filter net, so that the rainwater can contact the filter net evenly, making full use of every part of the filter net; improving the filtering effect; and at the same time increasing the use time of the filter net; through the setting of the support, the contact area between rainwater and the disinfectant can be increased, thereby improving the disinfection effect.

[0019] In some embodiments, each side surface is formed with a rotation groove corresponding to the rotation ring along the circumference of the side surface;

[0020] The rotating ring is located on one side close to the inner wall of the rotating groove and forms a gear ring along the circumferential direction;

[0021] The inner portion of the rotating groove radially penetrates into the interior of the support member to form a slot;

[0022] The number of teeth of two adjacent gear rings is set differently;

[0023] The above solution achieves the separation of the power component that can drive the filter to rotate from the filter itself, which makes it easier to handle consumable parts such as the filter; and eliminates the need for any maintenance of the support parts.

[0024] In some embodiments, the side wall of the rotating ring away from the gear ring forms a snap;

[0025] A clamping rod is fixed on a portion of the surface of the support surface away from the rotating ring;

[0026] The end of the clamping rod and the clamping buckle both form a clamping groove;

[0027] The filter screen is partially embedded in the two card slots and is clearance-matched with the card slots, so that the filter screen can be rotatably arranged on the buckle and the card rod;

[0028] The above solution facilitates the disassembly and assembly of the filter.

[0029] In some embodiments, a portion of the surface of the end of the clamping rod excluding the clamping groove is concave to form a rotation hole;

[0030] A scraper is provided for rotation in the rotating hole;

[0031] The scraper has a boss corresponding to the rotating hole so that the scraper can rotate in the rotating hole;

[0032] The scraper side at least contacts the surface of the filter screen, and the length is consistent with the width of the filter screen.

[0033] The above solution can achieve the goal of uniformly collecting impurities on the surface of the filter to one side, thereby improving the use effect of the filter.

[0034] In some embodiments, a driving structure for driving the gear ring to rotate is further provided in the cavity;

[0035] The drive structure includes:

[0036] a gear, meshing with the ring gear;

[0037] A support rod is rotatably disposed at the bottom of the cavity and supports the gear;

[0038] A rotating sleeve is arranged on the outer wall of the connecting pipe;

[0039] The turbine is rotatably arranged in the connecting sleeve and is partially connected to the rotating sleeve;

[0040] The rotating sleeve and the support rod transmit the rotating power through the chain;

[0041] By setting up the above scheme, it is achieved that the turbine is driven to rotate by the water flow, thereby driving the gear to rotate; and thus the rotation speed of the filter can be changed according to the flow rate of the water flow.

[0042] In some embodiments, a rotating tube fixedly connected to the turbine is further provided at the end of the connecting tube;

[0043] The rotating tube is rotatably arranged at the end of the supporting member;

[0044] A sealing cover is provided on the top of the rotating tube, and the sealing cover is dome-shaped;

[0045] Several flow guide tubes are provided on the side wall of the rotating tube;

[0046] The diversion pipe is L-shaped and is used to divert rainwater in the rotating pipe to flow vertically toward the support surface farthest from the bottom of the sealing chamber;

[0047] The above solution allows water to fall evenly in the circumferential direction above the support member, thereby improving uniformity.

[0048] In some embodiments, the extending direction of the side surface intersects the bottom surface of the sealed cavity to form a right angle;

[0049] The support surface and the side surface intersect in the same plane and form an angle α;

[0050] The value of the angle α is between 90° and 120°;

[0051] The above arrangement enables water to contact the supporting surface evenly.

[0052] In some embodiments, the bottom of the collection chamber forms a water reservoir for mounting a water pump;

[0053] The ground of the collection chamber is formed into a water storage tank with an inclined setting;

[0054] The water pump is powered by an external power supply;

[0055] A resistor assembly for controlling the water pump power is also installed in the cavity;

[0056] The above solution enables the power of the water pump to be adjusted through the resistor component.

[0057] In some embodiments, the resistor assembly is composed of a bracket, a porcelain cylinder, a coil, and a slider;

[0058] The support is fixed to the bottom of the cavity by screws;

[0059] The bracket is fixed with a porcelain cylinder wound with a coil;

[0060] The sliding plate is arranged on the bracket so as to move along the axial direction of the magnetic cylinder;

[0061] Among them, the position of the slider is moved to change the size of the resistance connected to the circuit;

[0062] The above solution realizes that the resistance can be changed by sliding the slider, and the power of the water pump can be changed by changing the size of the resistance.

[0063] In some embodiments, a slide bar is provided on the bracket for guiding the slide to move along the axial direction of the magnetic cylinder;

[0064] A screw rod rotatably arranged on the bracket and threadedly engaged with the sliding plate portion;

[0065] A gear disc is fixed at the end of the screw rod;

[0066] The bottom of the cavity is movably provided with a rack which engages with a toothed disc;

[0067] The rack part is located in the water storage tank, and a floating block is provided on the rack in the water storage tank;

[0068] Through the above solution, the greater the rainfall, the fuller the water tank is, so that the float can drive the rack to move, and then the size of the resistance can be adjusted. BRIEF DESCRIPTION OF THE DRAWINGS

[0091] Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although certain embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be construed as being limited to the embodiments described herein. On the contrary, these embodiments are provided to provide a more thorough and complete understanding of the present disclosure. It should be understood that the drawings and embodiments of the present disclosure are for illustrative purposes only and are not intended to limit the scope of protection of the present disclosure.

[0092] It should also be noted that, for ease of description, only the parts related to the invention are shown in the drawings. In the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0093] It should be noted that the concepts of "first" and "second" mentioned in this disclosure are only used to distinguish different devices, modules or units, and are not used to limit the order or interdependence of the functions performed by these devices, modules or units.

[0094] It should be noted that the modifications of "one" and "plurality" mentioned in the present disclosure are illustrative rather than restrictive, and those skilled in the art should understand that unless otherwise clearly indicated in the context, they should be understood as "one or more".

[0095] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0096] Reference Figure 1-9 , a rainwater collection and reuse system, comprising: a shell 1, a sealing shell 2, a connecting pipe 4, a water pipe 11, a water pump 5, a disinfection device 3, a filter 8, and a support member 7;

[0097] The housing 1 is cylindrical and forms a collection chamber a1 for collecting rainwater. A collection port a11 is formed at either end of the housing 1 to enter the collection chamber a1. Specifically, the collection port a11 is trumpet-shaped, which is conducive to receiving more rainwater.

[0098] Specifically, the side wall portion of the sealed shell 2 is fixedly connected to the inner wall of the collection chamber a1, and the sealed shell 2 forms a sealed chamber a2 for filtering rainwater; more specifically, a disinfectant 3 is installed at the inner top of the sealed chamber a2, and the disinfectant 3 is an ultraviolet disinfection device; a water pipe 11 is connected to the bottom of the sealed chamber a2, and the water pipe 11 is connected to an external water tank for storing water.

[0099] Specifically, the bottom of the sealed chamber a2 passes through the collecting chamber a1 to form a connecting pipe 4, and the bottom of the connecting pipe 4 is connected to the water pump 5, which is powered by an external power supply to give rainwater power to flow in the connecting pipe 4 to the sealed chamber a2; when rainwater enters the collecting chamber a1, water is pumped by the water pump 5 to divert the water from the connecting pipe 4 to the sealed chamber a2; then the water is disinfected and purified by the disinfector 3 in the sealed chamber a2; the sealed state of the seal a2 can make the disinfection effect more comprehensive and better; since the sealed shell 2 is located in the collecting chamber a1, the position for water purification is also in the shell 1; therefore, there is no need to connect an additional pipe to connect to another disinfection device; in this way, there is no need to set up a site for disinfection for disinfection, which improves space utilization.

[0100] Through the above scheme, when open to the open air, impurities will exist in the collection chamber a1. The suction from bottom to top by the water pump 5 replaces the traditional top-down method of collecting water, which can prevent the pipeline from being blocked by impurities and achieve a preliminary filtering effect.

[0101] In some embodiments, the bottom of the collection chamber a1 forms a water storage tank a12 for installing the water pump 5, and the floor of the collection chamber a1 forms a water storage tank a12 arranged at an angle; a resistor assembly 6 for controlling the power of the water pump 5 is also provided in the sealed chamber a2; the resistor assembly 6 is electrically connected to the water pump 5 and an external power supply;

[0102] More specifically, the resistor assembly 6 consists of a support 61, a ceramic tube 62, a coil 63, and a slider 64. The support is fixed to the bottom of the cavity a72 by screws. The support 61 is fixed with the ceramic tube 62 wound with the coil 63. The slider 64 is arranged on the support 61 and moves along the axial direction of the magnetic tube. The position of the slider 64 is moved to change the resistance of the circuit.

[0103] In some embodiments, a slide rod 65 is provided on the bracket 61 for guiding the slide 64 to move along the axial direction of the magnetic cylinder; a screw rod 66 is rotatably provided on the bracket 61 and is partially threadedly engaged with the slide 64; a toothed disc 67 is fixed at the end of the screw rod 66; a rack 69 is movably provided at the bottom of the cavity a72 and is engaged with the toothed disc 67; wherein the rack 69 is partially located in the water storage tank a12 and is provided with a float 68;

[0104] If the rainfall increases, the water level in the water storage tank a12 increases, and the float 68 floats up, driving the rack 69 to move, causing the toothed disc 67 to rotate, thereby driving the slide 64 to move, and the resistance decreases during the movement. It can be understood that when the rainfall is heavy, the water accumulation speed in the water storage tank a12 is greater than the pumping speed of the water pump 5, and the float 68 floats up, then causes the rack to move, and then drives the rotating disc to rotate, thereby driving the slide 64 to move. Therefore, the heavy rainfall and low resistance achieve a high power of the water pump 5, thereby improving adaptability.

[0105] In some embodiments, a support member 7 is fixed at the bottom of the sealed cavity a2, and the support member 7 is composed of several support surfaces a7 and side surfaces a71 connecting two adjacent support surfaces a7, and the support surfaces a7 are distributed in a stepped manner from bottom to top and form a cavity a72 inside the support member 7, so that the support member 7 as a whole is tower-shaped; more specifically, the part of the support member 7 in contact with the bottom of the sealed cavity a2 is defined as the tower bottom A1, and the part of the support member 7 away from the bottom of the sealed cavity a2 is defined as the tower top B1; wherein, the connecting pipe 4 passes through the support member 7 to the top of the tower B1, and the connecting pipe 4 located above the support member 7 forms a water outlet; preferably, the extension direction of the side surface a71 intersects with the bottom surface of the sealed cavity a2 to form a right angle; the support surface a7 and the side surface a71 intersect in the same plane and form an angle αa73; the value of the angle αa73 is between 90° and 120°; through this arrangement, water can flow naturally from the tower top B1 to the tower bottom A1.

[0106] The above solution allows water to flow naturally from the tower top B1 to the tower bottom A1. This arrangement enables the ultraviolet disinfection device to disinfect the water evenly, thereby improving the disinfection effect.

[0107] In some embodiments, an annular filter screen 8 is rotatably mounted on each support surface a7. Specifically, a rotating groove a8 is formed along the circumference of each side surface a71, and a rotating ring 80 is rotatably mounted within the rotating groove a8. The rotating ring 80 is located on a side adjacent to the inner wall of the rotating groove a8 and forms a toothed ring 81 along the circumference. The inner portion of the rotating groove a8 radially extends into the cavity a72 to form a slot a81. The number of teeth on two adjacent toothed rings 81 is different.

[0108] Specifically, the side wall of the rotating ring away from the gear ring 81 forms a buckle 82, and a clamping rod 83 is fixed on the surface of the support surface a7 away from the rotating ring, and the end of the clamping rod 83 and the clamping rod 82 both form a clamping groove a82; the filter screen 8 is partially embedded in the two clamping grooves a82, and is clearance-matched with the clamping groove a82, so that the filter screen 8 can be rotatably set on the buckle 82 and the clamping rod 83; the above scheme realizes that the rotating ring can be easily installed and disassembled; by setting up a rotating filter screen 8, the water will be evenly in contact with the filter screen 8 when filtering water, so that the filter screen 8 can be fully utilized and the filtering effect is improved; it can also be understood that the centrifugal force generated by the filter screen 8 during the rotation process can throw impurities to the outer ring of the filter screen 8.

[0109] More specifically, the surface of the end of the clamping rod 83 excluding the clamping groove a82 is concave to form a rotating hole, and a scraper 84 is rotatably arranged in the rotating hole; the scraper 84 has a boss 841 corresponding to the rotating hole so that the scraper 84 can rotate in the rotating hole, and the side of the scraper 84 at least contacts the surface of the filter 8, and the length is consistent with the width of the filter 8; with this arrangement, when the filter 8 starts to rotate, the impurities can be thrown to the outermost circle of the filter 8 due to the action of centrifugal force, and then collected by the scraper 84; on the one hand, this can prevent the impurities from being thrown into the water by the action of centrifugal force; on the other hand, the impurities on the filter 8 can be collected in one place, thereby increasing the utilization area of the filter 8 and improving the filtering effect.

[0110] In some embodiments, a driving structure 9 for driving the gear ring 81 to rotate is further provided in the cavity a72; the driving structure 9 includes: a gear 92, a support rod 91, a rotating sleeve 93, and a turbine 94;

[0111] Specifically, a support rod 91 is rotatably set at the bottom of the cavity a72, and a gear 92 meshing with the gear ring 81 is fixed at the end of the support rod 91; a rotating sleeve 93 is rotatably sleeved on the outer wall of the connecting pipe 4, and a turbine 94 is set on the rotating sleeve 93, and the turbine 94 is rotatably set in the connecting sleeve; when water passes through the turbine 94, it drives the turbine 94 to rotate, thereby driving the rotating sleeve 93 to rotate; further, the rotating sleeve 93 and the support rod 91 transmit rotational power through the chain 95; since the number of teeth of the two adjacent gear rings 81 are set differently, the transmission ratio of each rotating ring is also different; it can be understood that the rotation speed of the rotating rings arranged in sequence from the top of the tower B1 to the bottom of the tower A1 is set from fast to slow; since the water flow rate of the top of the tower B1 is greater than that of the bottom of the tower A1, the fast-rotating filter screen 8 can improve the filtering effect.

[0112] Specifically, a rotating tube 96 fixedly connected to the turbine 94 is further provided at the end of the connecting tube 4. The rotating tube 96 is rotatably mounted on the end of the support member 7. A dome-shaped sealing cover 97 is provided on the top of the rotating tube 96. A plurality of guide tubes 98 are provided on the sidewalls of the rotating tube 96. The guide tubes 98 are L-shaped and are used to guide rainwater in the rotating tube 96 vertically toward the support surface a7 farthest from the bottom of the sealed cavity a2.

[0113] Through the above scheme, firstly, the rotation of the turbine 94 drives the rotating tube 96, so that water can fall evenly in the circumferential direction of the tower top B1; the sealing cover 97 can concentrate water around the guide tube 98, so that the water outflow of the guide tube 98 is stable.

[0114] The above description is only an illustration of some preferred embodiments of the present disclosure and the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalent features without departing from the above-mentioned inventive concept. For example, the above-mentioned features are replaced with (but not limited to) technical features with similar functions disclosed in the embodiments of the present disclosure.
