[0019] The utility model provides a series connection facility for a flat grid type rainwater inlet as shown in Figures 1-4 Figure 4, which includes a rainwater branch pipe 1. A rainwater inspection well 101 is arranged at the input end of the rainwater branch pipe 1. A connecting pipe 2 is arranged at the water inlet end of the rainwater inspection well 101. A primary water inlet member is arranged at the water inlet end of the connecting pipe 2. A secondary water inlet member is arranged at the side of the primary water inlet member;

[0020] Specifically, the primary water inlet member includes a water inlet cylinder 3. A primary rainwater grate 301 is arranged at the top of the water inlet cylinder 3. The primary rainwater grate 301 is made of resin material;

[0021] The secondary water inlet member includes an extension pipe 4. A well seat 5 is arranged at the water inlet end of the extension pipe 4. A connecting frame 6 is arranged at the top of the well seat 5. A secondary rainwater grate 7 is inserted and connected to the top of the connecting frame 6. A closing cover 8 is arranged at the top of the connecting frame 6 and on the top of the secondary rainwater grate 7;

[0022] It should be noted that the well seat 5 is built with bricks and cement. A water inlet for the extension pipe 4 to penetrate is opened on its side. The diameter of the extension pipe 4 is 200 mm and the slope is 0.01. The connecting frame 6 and the well seat 5 are fixed with concrete. A placement groove 601 for the secondary rainwater grate 7 and the closing cover 8 to penetrate is opened at the top of the connecting frame 6. The placement groove 601 is a rectangular groove;

[0023] Specifically, locking hooks 701 are symmetrically arranged at the bottom side of the bottom of the secondary rainwater grate 7. The bottom of the locking hooks 701 is inserted and connected to the top of the connecting frame 6. A locking groove 602 for the locking hooks 701 to penetrate is opened at the bottom of the placement groove 601. Both the secondary rainwater grate 7 and the locking hooks 701 are made of ductile iron. The locking hooks 701 are L-shaped. The locking hooks 701 are L-shaped grooves. The user inserts the locking hooks 701 of the secondary rainwater grate 7 into the locking groove 602 and further pushes the secondary rainwater grate 7, so that the locking hooks 701 move in the locking groove 602, thereby locking the secondary rainwater grate 7 and the connecting frame 6;

[0024] A locking part for locking the position of the closing cover 8 is arranged at the top of the closing cover 8;

[0025] Specifically, the locking part includes a bolt 9. The bottom end of the bolt 9 is inserted and connected to the top of the closing cover 8.
