Description

Technical Field

[0001] This utility model relates to the technical field of rainwater harvesting devices, specifically a rainwater resource collection and water-saving device. Background Technology

[0002] Rainwater harvesting is the process of collecting rainwater, treating it, and then reusing it to obtain water that meets certain water quality standards.

[0003] The existing manhole covers on road rainwater collection inlets have large gaps, allowing rainwater to quickly drain into the collection inlets and eventually collect through underground pipes for subsequent treatment and use. This structure also allows some impurities such as leaves and pebbles to enter the rainwater collection inlets. If these impurities are not filtered, they will enter the underground pipes and cause blockages. Therefore, in order to filter impurities entering the rainwater collection inlets, a rainwater resource collection and water-saving device is proposed. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rainwater resource collection and water-saving device, comprising a rainwater collection assembly consisting of a well cover, a collection port, and a downpipe, wherein the downpipe is fixed to the bottom of the collection port, the collection port and the downpipe are pre-buried underground and the downpipe is inserted into the rainwater well, the well cover is closed on the top of the collection port, and a filter assembly is provided inside the collection port for filtering and intercepting impurities entering the collection port;

[0006] The filter assembly includes an n-shaped fold plate and a horizontal folded edge;

[0007] Multiple n-shaped folding plates are evenly arranged horizontally. The horizontal folding edge is fixed to one end of the side of the n-shaped folding plate. Adjacent n-shaped folding plates are connected and fixed by the horizontal folding edge. Filter holes are provided on the top, sides and upper surface of the horizontal folding edge of the n-shaped folding plate. The n-shaped folding plate and the horizontal folding edge form a filter structure for filtering impurities.

[0008] As a further embodiment of this utility model: the filter assembly also includes a guide plate, which is fixed to the side of the n-shaped folded plate and is inclined as a whole. The bottom end of the guide plate is fixedly connected to one end of the horizontal folded edge. The inclined slope of the guide plate is used to make the water flow towards the horizontal folded edge to impact.

[0009] As a further improvement of this utility model, the filter assembly also includes a rectangular outer frame;

[0010] The rectangular outer frame is distributed on the outside of the n-shaped fold plate, the horizontal fold edge, and the guide plate, and is welded and fixed to the inner wall of the rectangular outer frame on the outermost two sides of the guide plate, the top of the guide plate, both ends of the n-shaped fold plate, and the end of the horizontal fold edge away from the guide plate.

[0011] As a further embodiment of this utility model: the outer wall size of the rectangular outer frame matches the inner wall size of the collection port, a supporting grid is fixed on the inner side of the collection port, and the bottom ends of the rectangular outer frame, the n-shaped fold plate, and the horizontal fold edge are attached to the upper surface of the supporting grid.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figs. 1-4 In this embodiment of the utility model, a rainwater resource collection and water-saving device includes a rainwater collection component 1 consisting of a well cover 101, a collection port 102, and a drain pipe 103. The drain pipe 103 is fixed to the bottom of the collection port 102. The collection port 102 and the drain pipe 103 are pre-buried underground and the drain pipe 103 is inserted into the rainwater well. The well cover 101 covers the top of the collection port 102. A filter component 2 is provided inside the collection port 102. The filter component 2 is used to filter and intercept impurities that enter the collection port 102.

[0022] Filter assembly 2 includes an n-shaped fold plate 202 and a horizontal folded edge 203;

[0023] Multiple n-shaped folding plates 202 are evenly arranged horizontally. A horizontal folding edge 203 is fixed to one end of the side of the n-shaped folding plate 202. Two adjacent n-shaped folding plates 202 are connected and fixed through the horizontal folding edge 203. Filter holes 204 are provided on the top and sides of the n-shaped folding plate 202 and the upper surface of the horizontal folding edge 203. The n-shaped folding plate 202 and the horizontal folding edge 203 form a filter structure for filtering impurities.

[0024] The filter assembly 2 also includes a guide plate 205, which is fixed to the side of the n-shaped fold plate 202 and is inclined as a whole. The bottom end of the guide plate 205 is fixedly connected to one end of the horizontal fold 203. The inclined slope of the guide plate 205 is used to make the water flow towards the horizontal fold 203.

[0025] In this embodiment: When this device is in use, rainwater from the road surface flows into the rainwater well through the grid holes, filter holes 204, collection port 102, and drain pipe 103 on the manhole cover 101, and is collected through underground pipelines, thus achieving rainwater collection;

[0026] In this process, the corrugated structure composed of the n-shaped fold plate 202 and the horizontal folded edge 203 makes the distribution area of ​​the filter holes 204 larger than that of the horizontal plate structure, thereby achieving a high-efficiency filtration effect.

[0027] Meanwhile, the filtered impurities are collected in the middle area of ​​the two n-shaped baffles 202, while the impurities falling on the guide plate 205 are impacted by the water flow and converge towards the horizontal fold 203 area. In other words, the impurities will eventually be concentrated at the top of the horizontal fold 203. This makes it difficult for the filter holes 204 on the top and sides of the n-shaped baffles 202 to be blocked, thus maintaining a stable filtration effect for a long time. The concentration of impurities at the top of the horizontal fold 203 also facilitates subsequent cleaning operations.

[0028] Please refer to this carefully. Figs. 1-4 The filter component 2 also includes a rectangular outer frame 201;

[0029] The rectangular outer frame 201 is distributed on the outside of the n-shaped fold plate 202, the horizontal fold 203, and the guide plate 205, and is welded and fixed to the inner wall of the rectangular outer frame 201 on the sides of the outermost two guide plates 205, the top of the guide plate 205, both ends of the n-shaped fold plate 202, and the end of the horizontal fold 203 away from the guide plate 205.

[0030] The outer wall dimensions of the rectangular outer frame 201 match the inner wall dimensions of the collection port 102. A support grid 104 is fixed to the inner side of the collection port 102. The bottom ends of the rectangular outer frame 201, the n-shaped fold plate 202, and the horizontal folded edge 203 are attached to the upper surface of the support grid 104.

[0031] The upper surfaces of the rectangular outer frame 201 and the n-shaped folding plate 202 are flush with each other and with the upper surface of the collection port 102. The lower surface of the manhole cover 101 is in contact with the upper surfaces of the collection port 102, the rectangular outer frame 201, and the n-shaped folding plate 202.

[0032] In this embodiment: the rectangular outer frame 201 can shield the n-shaped fold plate 202, the horizontal fold edge 203, and the periphery of the guide plate 205, so that impurities will not scatter when the filter component 2 is removed;

[0033] In addition, the support grid 104 provides support for the filter assembly 2, which in turn provides support for the central area of ​​the manhole cover 101, thereby further improving the pressure-bearing performance of the manhole cover 101.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
