[0014] By adopting the above technical solution, a filter part is set up to collect garbage and impurities entering the drain trough, thereby reducing the situation where garbage and impurities block the drainage pipe. Secondly, when valuables fall into the drain trough, it is also easy to retrieve them from the filter part.

[0015] Optionally, the drainage hole wall is provided with a give way groove, the bottom of the give way groove is provided with an adjustment groove, the bottom of the adjustment groove is provided with an adjustment spring, the adjustment spring is connected with an adjustment block, the adjustment block is located at the end of the adjustment spring away from the bottom of the adjustment groove, and the end of the adjustment block away from the bottom of the adjustment groove is flush with the drainage hole wall.

[0016] By adopting the above technical solution and setting an adjustment block, when the drain board needs to be removed temporarily, the hand can be inserted into the drain hole and the drain board can be pulled close to the bottom of the drain trough. When the fingers are bent, they will contact the adjustment block and move, so as to provide bending space for the fingers, making it easy for people to take out the drain board without carrying tools.

[0017] In summary, the present application includes at least one of the following beneficial technical effects:

[0018] 1. Floating blocks are set. When the drainage holes are blocked or the drainage is poor due to heavy rain, water accumulates on the surface of the roof body, so the floating blocks move away from the bottom of the installation groove. The movement of the floating blocks connects the drainage channel to the connecting channel, thereby assisting the drainage of the accumulated water and reducing the accumulation of water on the roof body.

[0019] 2. Sliding convex strips and sliding grooves are provided, and the sliding convex strips are embedded in the sliding grooves to control the sliding direction of the floating block, thereby facilitating the connection between the drainage channel and the connecting channel, and reducing the situation of water accumulation on the roof body;

[0020] 3. Set up an adjustment block. When the drain board needs to be removed temporarily, put your hand into the drain hole and pull the drain board to the side close to the bottom of the drain trough. When your fingers are bent, they will contact the adjustment block and move, so as to provide bending space for your fingers and facilitate the removal of the drain board without carrying tools.
