Description

Technical Field

[0001] The utility model relates to the technical field of rainwater collection and reuse, in particular to a rainwater collection and reuse system suitable for a basement. Background Art

[0002] In order to effectively utilize rainwater resources, many places will collect and store rainwater by building underground reservoirs or rooftop reservoirs. For reservoirs specially dug underground, special construction is required, and the amount of work is large, resulting in high rainwater collection costs. Although rooftop reservoirs are cheaper, they are not suitable for small buildings. Because the rooftop reservoir in the water storage state puts a lot of pressure on the building, it will cause the collapse of small buildings, and the external water storage is easy to enter the impurities in the environment, affecting the water storage effect.

[0003] At present, a Chinese patent with the announcement number CN218027818U discloses a basement for building rainwater collection, including a basement body, a water storage tank is arranged in the basement body, a rainwater collection pipe is connected to the water storage tank, and a filtering mechanism is also arranged between the rainwater collection pipe and the water storage tank. The rainwater can be directly discharged through the first drain pipe for use after being filtered by the filtering mechanism, or stored in the water storage tank through the connection port. Specifically, the water in the water storage tank can be pumped out to the outside for use by a power device such as a water pump, for example, it can be used for fire fighting or green irrigation in the community. However, with the long-term use of the above-mentioned rainwater collection system, the filtering mechanism will gradually adhere to too many impurities and reduce the filtering effect. Although in the prior art, there is a filtering mechanism that cleans the filtering component through an internal cleaning component, the impurities cleaned out will enter the water storage tank with the water flow and pollute the water quality. Utility Model Content

[0004] The utility model aims to overcome the deficiencies of the prior art and provide a rainwater collection and reuse system suitable for basements.

[0005] The purpose of this utility model is achieved through the following technical solutions:

A filter component and a cleaning component are arranged in the filter box. A sewage outlet is also provided on the filter box. The sewage outlet is connected to a sewage collection box. When the cleaning component cleans the filter component, the water outlet of the filter box is closed and the sewage outlet is opened.

[0007] The cleaning component comprises an ultrasonic generator. When the ultrasonic generator is in operation, the water outlet and the sewage outlet of the filter box are both in a closed state.

[0008] The cleaning component includes a water pump pipe connected to the water storage tank, the water pump pipe is connected to the water inlet of the filter box, and the water pump pipe is adapted to pump the water in the water storage tank into the filter box under the action of a water pumping device to drive the water flow to impact the filter component.

[0009] The filter component includes a plurality of filter screens arranged side by side, and the filter screens are adapted to be movable under the drive of a driving member. When water flows into the filter box, the plurality of filter screens move in sequence along the direction of the water flow to drive the water flow to impact different filter screens.

[0018] The following will be combined with the embodiments to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0019] A rainwater collection and reuse system suitable for a basement includes a rainwater collection pipe 1, a filter box 2, and a water storage tank 3 which are arranged in the basement and connected in sequence. The rainwater collection pipe 1 can collect rainwater from the ground or the roof of a building and introduce it into the filter box 2, and the filter box 2 filters the water flow through the filter component 4. The filtered water will be introduced into the water storage tank 3 through the water outlet 14 of the filter box 2 for storage. When water is needed, the water in the filter box 2 can be pumped out to the outside for use through a pumping device (not shown), for example, it can be used for fire fighting or green irrigation in a community.

[0020] A cleaning member 5 is also provided in the filter box 2. After the filter box 2 is used for a long time, too many impurities will gradually adhere to the filter member 4, thereby reducing the filtering effect. At this time, the filter member 4 can be cleaned by the cleaning member 5, without disassembling the filter box 2 as a whole to clean the filter member 4. However, the impurities cleaned out will flow into the water storage tank 3 with the water flow and pollute the water quality.

[0021] In view of the above technical problems, in the present disclosure, a sewage outlet 6 is also provided on the filter box 2, and the sewage outlet 6 is connected to a sewage collecting box 7. For example, electromagnetic opening and closing valves are provided in the water outlet 14 and the sewage outlet 6 of the filter box 2. When the filter element 4 needs to be cleaned, the water outlet 14 of the filter box 2 can be controlled to be in a closed state, while the sewage outlet 6 is in an open state, so that impurities will be collected in the sewage collecting box 7 along with the water flow through the sewage outlet 6, and it is not easy for impurities to enter the water storage tank 3 and cause pollution.

[0022] In some embodiments, the cleaning member 5 may include an ultrasonic generator 8 disposed in the filter box 2. Furthermore, it is also preferred that when the ultrasonic generator 8 is in operation, the water outlet 14 and the sewage outlet 6 of the filter box 2 are controlled to be in a closed state. For example, when rainwater enters the filter box 2, since the water outlet 14 and the sewage outlet 6 are both in a closed state, the ultrasonic generator 8 is more likely to cause the vibration of microbubbles in the water, and the impurities adhering to the filter member 4 are removed by the principle of ultrasonic cleaning. After the ultrasonic cleaning is completed, the sewage outlet 6 is controlled to be opened, and the water outlet 14 is kept closed, and then the impurities will flow into the sewage collection box 7 to complete the entire cleaning operation.

[0023] As another solution, the cleaning component 5 may also preferably include a water pump pipe 9 connected to the water storage tank 3. For example, the water pump device may also be adapted to pump the water in the water storage tank 3 into the filter box 2 through the water pump pipe 9, and the water pump pipe 9 may generate an impact water flow to the filter component 4, thereby removing impurities adhering to the filter component 4 by impact.

[0024] In the process of the water flow impacting and removing the filter element 4, the water outlet 14 can be controlled to be in a closed state and the sewage outlet 6 can be controlled to be in an open state, and the water flow will directly carry the impurities impacted and collect them in the sewage collection box 7, thereby simplifying the opening and closing control actions of the water outlet 14 and the sewage outlet 6, and improving the efficiency of the cleaning operation. In addition, after the filter element 4 is cleaned, the water in the water storage tank 3 can continue to be pumped into the filter box 2 through the pump pipe 9 to achieve secondary filtration, for example, to prevent the water quality of the water in the water storage tank 3 from being deteriorated after being left for too long.

[0025] In a preferred example, the filter member 4 includes a plurality of filter screens 10 arranged side by side. For example, the plurality of filter screens 10 are all rotatably arranged in the filter box 2. In addition, a driving member is also provided on the filter box 2, through which the plurality of filter screens 10 can be driven to rotate in sequence along the impact direction of the water flow, thereby driving the water flow to impact different filter screens 10. It can be understood that due to the rotation avoidance of the previous filter screen 10, the water flow can impact the next filter screen 10 in a state of greater kinetic energy, and at this time, impurities adhering to it are more easily removed by impact.

[0026] For example, the rotating shafts of the plurality of filter screens 10 are arranged on the same side and opposite to each other, and racks 12 are arranged on the plurality of rotating shafts. The driving member may include the rack 12 which is ejected by the electric cylinder 13 arranged on the filter box 2. As the rack 12 is ejected, the plurality of gears 11 will mesh with the rack 12 one by one, thereby driving the plurality of filter screens 10 to rotate in sequence.

[0027] As another solution, a plurality of filter screens 10 can also be slidably fitted in the filter box 2 in a manner similar to a drawer (not shown), and the driving member can achieve the above-mentioned technical effect of water flow impacting different filter screens 10 in turn by pushing the plurality of filter screens 10 one by one, so that impurities can be more easily removed by the impact.

[0028] The above is only a preferred embodiment of the utility model. It should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not deviate from the spirit and scope of the utility model, and should be within the scope of protection of the claims attached to the utility model.
