[0030] 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.

[0031] Example 1

[0032] refer to Figures 1-6 A modular rainwater inlet includes a base 1, a base block 2, a grate assembly 3, a drain pipe 4, and at least one connecting block 5, wherein the base block 2 is connected above the base 1.

[0033] The top of the connecting block 5 is provided with a first step 51, the bottom of the connecting block 5 is provided with a second step 52, and the top of the base block 2 is provided with a third step 21. The connecting block 5 is erected on top of the base block 2 through the cooperation of the second step 52 and the third step 21. Multiple connecting blocks 5 can be erected layer by layer through the cooperation of the first step 51 and the second step 52.

[0034] The connecting block 5 and the base block 2 cooperate on the base 1 to form a well wall; the grate assembly 3 is connected to the top of the well wall; the drain pipe 4 passes through the well wall, with one end extending into the well wall and the other end located outside the well wall.

[0035] In this design, the base 1 is generally a concrete structure. Using the base 1 as a foundation, the base block 2 is placed on top of it. When the depth of the rainwater inlet is shallow, a connecting block 5 is installed on the base block 2 through the cooperation of the second step 52 and the third step 21. The cooperation between the connecting block 5 and the base block 2 forms a well wall on the base 1. Then, the grate assembly 3 is installed on top of the well wall. When the depth of the rainwater inlet is deeper, workers can assemble and splice multiple connecting blocks 5. The upper connecting block 5 cooperates with the lower connecting block 5's first step 51 through the cooperation of the second step 52 at the bottom, allowing multiple connecting blocks 5 to be stacked layer by layer upwards to increase the height of the well wall. This method reduces the difficulty of construction for workers when splicing the well wall, speeds up the entire construction process, improves work efficiency, and allows for flexible adjustment of the well wall height.

[0036] It should also be noted that base block 2 and connecting block 5 can be prefabricated in the factory, transported directly, and installed in a modular manner.

[0037] In this embodiment, a trap basket 6 is also included. The first step 51 has a first step surface 511 and a second step surface 512. The first step surface 511 is located above the second step surface 512, and the second step surface 512 is located on the inner side of the first step surface 511.

[0038] The grate assembly 3 is disposed on the first step surface 511 of the top connecting block 5, and the sewage intercepting basket 6 is disposed on the second step surface 512 of the top connecting block 5.

[0039] The structure of the intercepting basket 62 has been disclosed in Chinese patent CN216586917U, so the structure of the intercepting basket 62 will not be described in detail in this embodiment.

[0040] Generally speaking, the grate assembly 3 can prevent leaves, branches, plastic bags, garbage, etc. from entering the drain pipe 4 to avoid blockage. The intercepting basket 6 is used for further filtration to reduce the accumulation of garbage. Moreover, the intercepting basket 6 is set on the second step surface 512, which makes it easier for workers to clean.

[0041] The second surface 512 is located on the inner side of the first surface 511, so that the connecting blocks 5 are limited when multiple connecting blocks 5 are assembled.

[0042] Preferably, the base 1 includes a base plate 11 and a permeable concrete seat 12 disposed on the base plate 11, the side of the permeable concrete seat 12 is in contact with the soil, and the base block 2 is disposed on the top of the permeable concrete seat 12.

[0043] Specifically, since the drainage pipe 4 itself has a certain height, water located on the well wall and below the drainage pipe 4 cannot enter the drainage pipe 4 and thus accumulates at the bottom of the well wall, which can easily breed mosquitoes. Therefore, a permeable concrete seat 12 is set on the base plate 11, and the side of the permeable concrete seat 12 is in contact with the soil. The accumulated water seeps into the permeable concrete seat 12 and then into the soil. In this way, the accumulated water in the well wall is drained.

[0044] More preferably, the grate assembly 3 includes a grate seat 31 and a grate 32, wherein the grate seat 31 is connected to the top of the well wall through a first adhesive layer 7, and the grate 32 is disposed inside the grate seat 31.

[0045] The structure of the comb base 31 and the comb 32 has been disclosed in Chinese patent CN209941854U, so the structure of the comb base 31 and the comb 32 will not be described in detail in this embodiment.

[0046] Generally, the first bonding layer 7 can be made of cement mortar. The cement mortar is applied to the bottom of the grate seat 31 and then connected to the top of the well wall with cement mortar.

[0047] In this embodiment, when multiple connecting blocks 5 are layered together, the first step 51 and the second step 52 are connected by a second adhesive layer 8. The second adhesive layer 8 can be cement mortar or waterproof materials such as waterproof membrane. When multiple connecting blocks 5 are laid together, cement mortar is used to connect the multiple connecting blocks 5 on the surface of the first step 51 or the second step 52. In addition, in a preferred embodiment, the drainage pipe 4 and the base block 2 are sealed using a method well known to those skilled in the art; in other embodiments, it is only necessary to ensure the stability of the drainage pipe 4 connected to the base 2, and cement mortar can be used to fill the gaps to collect rainwater as much as possible.

[0048] Preferably, the bottom of the base block 2 and the base 1 are connected by a third adhesive layer 9. The third adhesive layer 9 can be cement mortar, which is used to connect the bottom of the base block 2 and the base 1.

[0049] Preferably, the bottom of the base block 2 is provided with a groove 22, the lower end of the groove 22 is open, and the third adhesive layer 9 fills the groove 22. The bottom of the base block 2 has a groove 22. When connecting the base block 2 to the base 1, cement mortar is applied to the bottom surface of the base block 2 and the cement mortar is filled into the groove 22. Then the base block 2 is placed on the base 1, and the base block 2 and the base 1 are connected by applying cement mortar.

[0050] Preferably, the drain pipe 4 is located at the bottom of the well wall, and the top surface of the permeable concrete seat 12 slopes from the well wall toward the inlet end of the drain pipe 4. Placing the drain pipe 4 at the bottom of the well wall can reduce water accumulation inside the well wall, and the sloping arrangement can better guide rainwater into the drain pipe 4.

[0051] In this embodiment, the second step 52 has a third step surface 521 and a fourth step surface 522, the third step surface 521 is located above the fourth step surface 522, and the fourth step surface 522 is located on the inner side of the third step surface 521.

[0052] The third step 21 has a fifth surface 211 and a sixth surface 212. The fifth surface 211 is located above the sixth surface 212, and the sixth surface 212 is located on the inner side of the fifth surface 211.

[0053] Specifically, the second step 52 is located at the bottom of the connecting block 5, and the third step 21 is located at the top of the base block 2. In this way, the second step 52 and the third step 21 can work together to limit the connection block 5.

[0054] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements or modifications can be made without departing from the principle of the present utility model, and these improvements or modifications should also be considered within the protection scope of the present utility model.
