Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of rainwater collection building components, and in particular relates to a rainwater collection PP module with a backwash flow channel. Background Art
[0002] The PP modular system collects rainwater runoff generated by different underlying surfaces and reuses it after proper treatment. This can not only replace the use of part of the tap water, but also reduce the pressure on the urban drainage system.
[0003] PP modular rainwater storage tanks are typically composed of multiple PP modules, each designed to specific standards for size and pressure-bearing capacity. Modules are securely connected using connectors and sockets. Conventional PP modules are stacked and connected layer by layer using intermittent components. When collected rainwater contains significant sediment, the sediment will gradually settle at the bottom of the tank, burying it and making it difficult to clean. Utility Model Content
[0004] In order to solve the above technical problems, the purpose of the present utility model is to provide a rainwater collection PP module with a backwash flow channel, which can precipitate the sediment in the rainwater through the backwash flow channel to avoid burying the PP module at the bottom of the module pool.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0006] A rainwater collection PP module with a backwash flow channel includes a module body, wherein the edges of the upper end face of the module body are provided with cavities, and the upper end face of the module body enclosed by the cavities is arrayed with seepage pipes passing through the module body, and the lower end face of the module body is provided with a socket that passes through the seepage pipe and is used to insert the seepage pipe; a connecting hole is provided in the center of the module body, and the connecting hole is used to plug in the connecting column to vertically stack the PP modules.
[0007] Furthermore, the cavity passes through the module body, both ends of the cavity intersect and penetrate, and detachable baffles are provided on both end edges of the cavity.
[0008] Furthermore, the cross section of the cavity is U-shaped.
[0009] Furthermore, trapezoidal connecting grooves are provided around the upper end surface of the module body, and the trapezoidal connecting grooves are used to insert connecting blocks to connect adjacent PP modules horizontally.
[0010] Furthermore, both ends of the cavity bottom are provided with a card slot, and the baffle is inserted into the card slot.
[0011] Furthermore, the circumferential array of the seepage pipes is arranged around the center of the module body, and the seepage pipes pass through the module body.
[0012] Furthermore, the connecting hole is a blind hole, and the closed end of the blind hole is located at the lower end surface of the module body.
[0013] Furthermore, the connecting hole is a through hole.
[0014] Furthermore, the lower end surface of the module body is grid-shaped.
[0015] Due to the adoption of the above technical solution, the utility model has the following advantages and effects:
[0016] The utility model provides a rainwater collection PP module with a backwash flow channel. By arranging an enclosed cavity at the outer peripheral edge of the module body, the silt in the rainwater flowing into the module pool can be precipitated through the cavity to prevent the silt from entering the bottom of the module pool. At the same time, the silt settled in the cavity can be flushed and reused after the module is disassembled, avoiding the time-consuming and labor-intensive problem of excavating and cleaning the module pool.

[0023] The following will be combined with the accompanying drawings to describe the embodiments of the present invention in detail so that the purpose, features and advantages of the present invention can be more clearly understood. It should be understood that the embodiments shown in the accompanying drawings are not intended to limit the scope of the present invention, but are only intended to illustrate the essential spirit of the technical solution of the present invention.
[0024] like Figure 1-Figure 5The utility model provides a rainwater collection PP module with a backwash trough, comprising a module body, wherein the upper end surface of the module body is provided with a cavity 1 around the edges thereof, the lower end surface of the module body is provided with a socket which is connected to a seepage pipe 2 and is used to insert the seepage pipe 2; and the center of the module body is provided with a connection hole 5 which is used to insert a connection column to connect the PP modules vertically stacked.
[0025] Specifically, the module bodies are square plate-like structures. When stacked vertically, the upper and lower modules are connected by connecting posts inserted into connection holes 5, and seepage pipes 2 are simultaneously inserted into sockets. Cavities 1 are located along the edges of the module bodies to collect sediment from rainwater, and seepage pipes 2 allow water to seep between the stacked PP modules.
[0026] In order to prevent the connection column from rotating, the cross section of the connection hole 5 is a polygonal structure or a plum blossom structure, and the shape of the connection column matches the shape of the connection hole 5 .
[0027] Furthermore, the cavity 1 passes through the module body, and both ends of the cavity 1 intersect and penetrate each other. Removable baffles are provided on the edges of both ends of the cavity 1.
[0028] Specifically, in order to facilitate one-piece molding processing, both ends of the cavity 1 pass through the outer peripheral surface of the module body, and the tail ends of the cavity 1 intersect and connect with each other. Baffles are set at both ends of the cavity 1 to close the cavity 1 to facilitate the collection of mud and sand in the cavity 1, and when the cavity 1 needs to be cleaned, the baffle can be removed to flush the cavity 1.
[0029] Furthermore, the cross section of the cavity 1 is U-shaped. The U-shaped cross section is not only convenient for rainwater to flow through, but also convenient for cleaning and forming the cavity 1.
[0030] Furthermore, trapezoidal connecting grooves 3 are provided around the upper end surfaces of the module bodies. These grooves are used to insert connecting blocks, connecting adjacent PP modules horizontally. One end of the groove 3 extends through the perimeter of the module body, and the opening of the groove 3 on one side is larger than the opening on the other side. This facilitates the connection of two modules when they are horizontally connected. Once the pair of grooves 3 are interpenetrating, the connecting blocks can be inserted into the grooves to connect the two opposing modules. The shape of the connecting blocks matches the groove cavities of the pair of interpenetrating grooves 3.
[0031] Furthermore, the bottom of both ends of the cavity 1 is provided with a slot 4, and the baffle is inserted into the slot 4. The shape of the slot 4 is consistent with the cross-sectional shape of the cavity 1, and the shape of the baffle is consistent with the cross-sectional shape of the cavity 1. The baffle is inserted into the slot 4 to seal the two ends of the cavity 1, so that the cavity 1 on all sides is connected to form a zigzag channel to effectively block mud and sand.
[0032] Furthermore, a circular array of seepage pipes 2 is arranged around the center of the module body, and the seepage pipes 2 pass through the module body. In the present invention, four seepage pipes 2 are arranged, the upper ends of the seepage pipes 2 extend out of the upper end surface of the module body, and the lower ends of the seepage pipes 2 do not exceed the lower end surface of the module body.
[0033] Furthermore, the connection hole 5 is a blind hole, the closed end of which is located at the lower end surface of the module body. When the PP module is located at the bottom of the module pool, the blind hole can be used as a socket to support one end of the bottom connection column.
[0034] As a preferred embodiment, when the PP module is not arranged at the bottom layer of the module pool, the connection hole 5 is a through hole, which facilitates the insertion of the connection column from top to bottom into the upper and lower adjacent PP modules to realize the vertical connection of the PP modules.
[0035] Furthermore, in order to increase the strength of the module body, the lower end surface of the module body is in a grid shape. The grid is a square grid, and one of the grids can be used as a socket for the seepage pipe 2 to facilitate the insertion of the seepage pipe 2.
[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
