Description

Technical Field

[0001] The utility model relates to the technical field of rainwater collection devices, and specifically relates to a rainwater collection and reuse device for houses. Background Technique

[0002] At present, in some parts of our country, there is a shortage of water resources, and the collection and utilization of rainwater can appropriately alleviate the water shortage situation. Rainwater can be collected on the roof. Compared with ground rainwater, roof rainwater has the advantages of better water quality and being convenient for collection.

[0003] The Chinese utility model patent, with the authorization announcement number CN219909675U, discloses a rainwater collection and reuse device for houses, belonging to the technical field of rainwater collection. This device realizes the automatic cleaning of the filter screen and improves the cleaning quality.

[0004] The above solution solves the technical problems it proposed. However, in actual application, the above solution still has certain defects. First, after the rainwater gathers on the roof and enters the rainwater collection tank through the pipeline, if the rainfall is concentrated and the amount of water entering the pipeline is large, under the action of its potential energy, the rainwater will impact the rainwater collection tank, resulting in a large noise generated by the vibration of the rainwater collection tank. Second, although the rainwater passes through a primary filtration, there are still some sand and stones entering the rainwater collection tank along with the water flow. After a long time, the sand and stones will precipitate in the rainwater collection tank, reducing the rainwater collection capacity of the rainwater collection tank, and it is necessary to frequently clean the rainwater collection capacity manually. Content of the Utility Model

[0020] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0021] The rainwater collection and reuse device for houses is provided with a vertical pipe, a water inlet elbow, a middle elbow, a vertical rod and a spiral blade.

[0024] In addition, a first filter element and a driving element are also provided. The controller controls the telescopic rod at the top of the double-headed hydraulic cylinder to expand and contract, drives the filter plate to move up and down through the cam, makes the filter plate vibrate, and the impurities such as leaves, tiles or stones attached to the top of the filter plate are separated from the filter plate and finally discharged from the through slot at the top of the filter plate into the water receiving tank, thus eliminating the need for manual cleaning of the filter plate and saving labor.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0031] As Figures 1 - 4 shown, the present utility model provides a technical solution: a device for collecting and reusing rainwater in a house, which includes a water receiving tank 1 and a collection tank 5. The water receiving tank 1 is fixed on the side of the wall and is located at the bottom of the roof discharge groove for receiving the rainwater discharged through the roof discharge groove. A first filter element 2 is provided on the top of the water receiving tank 1 to filter large impurities in the roof rainwater. The collection tank 5 is located at the bottom of the water receiving tank 1, and the collected rainwater is finally stored in the collection tank 5. The user can open the valve of the water outlet pipe at the bottom of the collection tank 5, and the rainwater flows out through the water outlet pipe to realize the reuse of rainwater.

[0032] A vertical pipe 6 is fixedly communicated at the bottom of the water receiving tank 1. A connecting pipe is fixedly communicated at the top of the collection tank 5. The connecting pipe is fixedly communicated with the vertical pipe 6, and a U-shaped pipe is formed at the connection. An impurity collection pipe 801 is fixedly communicated at the bottom of the U-shaped pipe. In addition, a vertical rod 901 is arranged inside the vertical pipe 6. A spiral blade 902 is fixed between the vertical rod 901 and the side wall of the vertical pipe 6, and the spiral blade 902 and the vertical rod 901 extend into the U-shaped pipe. In a specific embodiment of this solution, as Figure 1 and Figure 3 shown, the connecting pipe includes an inlet elbow 7 and a middle elbow 8. The middle elbow 8 is detachably fixed between the vertical pipe 6 and the inlet elbow 7 through a flange, and the impurity collection pipe 801 is fixedly communicated with the bottom of the middle elbow 8.

[0033] When a large amount of rainwater flows down through the water receiving tank 1, when the water flow passes through the spiral blade 902, the water flow is affected by the shape and friction of the spiral blade 902, so that the speed and energy of the water flow are lost, and the kinetic energy of the outlet water is lower than that in the case of direct falling. Moreover, the spiral blade 902 can make the energy distribution of the water flow more uniform, thereby reducing the impact force on the middle elbow 8, the inlet elbow 7 and the collection tank 5, improving the service life of the device and reducing noise at the same time.

[0034] In addition, after the water flow flows out through the spiral blade 902, a rotational movement will be generated, which will roll up the sediment deposited on one side of the middle elbow 8, thus preventing the blockage of the middle elbow 8 caused by a large amount of sediment deposition, reducing the frequency of manual cleaning, and the sediment flowing at the bottom enters the impurity collection pipe 801 under the action of its gravity for sedimentation. When the device is not in use, opening the lid at the bottom of the impurity collection pipe 801 can clean the sediment deposited in the impurity collection pipe 801, without the need to clean the entire pipeline, further reducing the labor consumption.

[0035] As Figure 3 shown, in order to reduce the sediment in the rainwater entering the collection box 5 and facilitate the reuse of rainwater, a second filter element 10 is provided at the top of the collection box 5. Among them, the second filter element 10 includes a mounting frame 101 that is movably inserted into the collection box 5, and a filter screen 102 is fixed inside the mounting frame 101. Some small-particle sediment enters the collection box 5 along with the water flow, and the sediment is filtered through the filter screen 102. During cleaning, the mounting frame 101 is pulled out to clean the filter screen 102. This device improves the cleanliness of rainwater through multi-stage filtration of rainwater.

[0036] As Figure 3 and Figure 4 shown, a plugging member 3 is provided at the bottom of the first filter element 2, and a driving member is provided between the first filter element 2 and the plugging member 3.

[0037] Among them, the first filter element 2 includes a first connecting shaft 201 that is movably connected to the top of the water receiving tank 1. A downwardly inclined through groove is provided on the side surface of the water receiving tank 1. A downwardly inclined filter plate 202 is fixed on the shaft body of the first connecting shaft 201. The bottom plate body of the filter plate 202 movably penetrates through the through groove, that is, the filter plate 202 can move up and down within a small range around the first connecting shaft 201 in the through groove. A rotating shaft 203 is movably connected to the side surface of the water receiving tank 1, and a cam 204 is fixed on the shaft body of the rotating shaft 203, and the surface of the cam 204 is in contact with the bottom plate body of the filter plate 202. The plugging member 3 includes a third connecting shaft fixed to the bottom of the water receiving tank 1, and a plugging plate 301 is movably connected to the shaft body of the third connecting shaft. When the water receiving tank 1 is in the water storage state, the plugging plate 301 plugs the water outlet of the water receiving tank 1. In order to improve the stability of the plugging plate 301 in plugging the water outlet, a counterweight is fixed at the bottom end of the plugging plate 301. In the plugged state, the counterweight is located inside the water outlet of the water receiving tank 1.

[0038] A rectangular groove is provided on the side surface of the water receiving tank 1, a second connecting shaft 302 is fixed between the side walls of the rectangular groove, and a movable plate 303 is movably connected to the shaft body of the second connecting shaft 302. A pull rope 304 made of a steel wire material is connected between the plate body of the movable plate 303 extending into the water receiving tank 1 and the plugging plate 301.

[0039] In addition, the driving member includes a double-headed hydraulic cylinder 401 fixed to the side wall of the water receiving tank 1 and a controller. The bottom telescopic rod of the double-headed hydraulic cylinder 401 contacts the top plate body of the movable plate 303. A toothed plate 402 is fixed to the top telescopic rod thereof. A gear is fixed to the shaft body of the rotating shaft 203 extending out of the water receiving tank 1, and the gear meshes with the toothed plate 402. A water level detector 11 for real-time monitoring of the water level in the water receiving tank 1 is fixed to the inner wall of the water receiving tank 1. The controller is electrically connected to the water level detector 11 and the double-headed hydraulic cylinder 401 respectively.

[0040] The purposes of setting the first filter member 2, the blocking member 3 and the driving member are as follows: Firstly, to vibrate the filter plate 202, so as to separate impurities such as leaves, tiles or stones attached to the top of the filter plate 202 from the filter plate 202, and finally discharge them from the through slot at the top of the filter plate 202 out of the water receiving tank 1, eliminating the need for manual cleaning of the filter plate and saving manpower. Secondly, to achieve centralized water inlet, and the water flow performs spiral flushing on the U-shaped pipe at the connection of the vertical pipe 6 and the water inlet elbow 7, preventing sediment from depositing in the pipeline and reducing the difficulty of later pipeline cleaning.

[0041] Specifically, during operation, the controller controls the telescopic rod at the top of the double-headed hydraulic cylinder 401 to extend and retract. When the toothed plate 402 moves up and down, it drives the gear to rotate clockwise and counterclockwise alternately, thereby driving the filter plate 202 to move up and down through the cam 204, causing the filter plate 202 to vibrate, and separating impurities such as leaves, tiles or stones attached to the top of the filter plate 202 from the filter plate 202, and finally discharging them from the through slot at the top of the filter plate 202 out of the water receiving tank 1. When the water level detector 11 detects that the water volume in the water receiving tank 1 reaches the set value, the controller controls the telescopic rod at the bottom of the double-headed hydraulic cylinder 401 to extend. The telescopic rod squeezes the movable plate 303 downward, and the movable plate 303 rotates clockwise around the second connecting shaft 302. The movable plate 303 pulls the blocking plate 301 to remove the blockage of the water outlet of the water receiving tank 1, and the water flow enters the vertical pipe 6 through the water outlet.

[0042] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended embodiments and their equivalents.
