Description

Technical Field

[0001] The utility model belongs to the technical field of drainage systems, and specifically refers to a downpipe filter which automatically diverts falling water and roof garbage. Background Art

[0002] When it rains, garbage on the roof, such as leaves, will flow into the downpipes along with the rainwater. Downpipe filters are used to filter out the garbage that may accumulate in the pipes, thereby preventing the downpipes from clogging. Traditional downpipe filters require manual cleaning of the filter screen. If not maintained in time, the filter screen will become clogged, resulting in poor drainage. This also requires the drainage system to maintain a short maintenance cycle, and the manual maintenance cost is high. Summary of the invention

The filter can realize automatic diversion of falling water and roof garbage. After being diverted, the roof garbage will accumulate outside the filter, which greatly reduces the risk of filter clogging, prolongs the filter maintenance cycle, and reduces labor maintenance costs.

[0011] One side of the L-shaped water baffle is against the top of the square box and is hinged inside the square box;

[0012] The included angle between the two surfaces of the L-shaped water retaining plate is greater than 90° and less than 180°.

[0013] Furthermore, the filter screen is a structure of several first thin rods with hook-shaped ends arranged side by side at equal intervals, a second thin rod is connected to each head and tail of the filter screen, and the hook-shaped end of the filter screen abuts against the lower baffle.

[0014] Furthermore, two sides of the square box adjacent to the inspection door protrude outward to form a flow limiting plate.

[0015] Furthermore, the upper tube and the lower tube are both socket-type structures.

[0016] Furthermore, the square box, the upper tube and the lower tube are made of metal.

[0028] like Figures 1 to 6 As shown, a downpipe filter for automatically diverting falling water and roof garbage comprises: a square box 1, an upper pipe 2 and a lower pipe 3;

[0029] The top of the square box 1 is connected to the lower end of the upper tube 2, and the bottom is connected to the upper end of the lower tube 3. The square box 1, the upper tube 2 and the lower tube 3 are interconnected;

[0030] An inspection door 11 is provided on one side of the square box 1, and an upper baffle 12 and a lower baffle 13 are provided above and below the inspection door 11. The inspection door 11 is hinged on the square box 1 against the upper baffle 12 and can be turned upside down;

[0031] A filter screen 4 is placed in the square box 1;

[0032] The filter screen 4 is placed obliquely in the square box 1 against the lower baffle 13 .

[0033] Furthermore, an L-shaped water retaining plate 5 is provided on the top of the square box 1;

[0034] One side of the L-shaped water baffle 5 is against the top of the square box 1 and is hinged inside the square box 1;

[0035] The included angle between the two sides of the L-shaped water retaining plate 5 is greater than 90° and less than 180°.

[0036] Furthermore, the filter screen 4 is a structure of a plurality of first thin rods 41 with hook-shaped ends arranged side by side at equal intervals, a second thin rod 42 is connected to the head and tail of each of the filter screens 4 , and the hook-shaped ends of the filter screens 4 abut against the lower baffle 13 .

[0037] Furthermore, two sides of the square box 1 adjacent to the inspection door 11 protrude outward to form a flow limiting plate 14.

[0038] Furthermore, the upper tube 2 and the lower tube 3 are both socket-and-spigot structures.

[0039] Furthermore, the square box 1, the upper tube 2 and the lower tube 3 are made of copper.

[0040] Furthermore, the L-shaped water guide plate 5 is made of copper.

[0041] Furthermore, the filter screen 4 is made of stainless steel or copper.

[0042] When draining, Figure 7 As shown, the falling water passes through the upper pipe 2, the filter screen 4 and the lower pipe 3 in sequence. Roof garbage such as fallen leaves are blocked by the filter screen 4, and slide down along the filter screen 4 with the help of the impact of falling water, and accumulate on the inside of the inspection door 11. When the accumulation reaches a certain level, the roof garbage will push the inspection door 11 to flip up and down, and then the roof garbage will be separated from the filter and accumulated outside the filter, achieving the effect of automatically separating the falling water and the roof garbage.

[0043] When falling water falls, it will be guided to the inside of the filter by the L-shaped water guide plate 5 to prevent overflow. The flow limiting plate 14 can limit the flow of water overflowing from the inspection door 11 in extreme cases to prevent overflow to the surroundings. The filter screen 4 can also be taken out of the square box 1 for maintenance at any time.

[0044] The utility model has the advantages of realizing automatic diversion of falling water and roof garbage, and the roof garbage will be accumulated outside the filter after being diverted, which greatly reduces the risk of filter clogging, prolongs the filter maintenance cycle, and reduces manual maintenance costs.

[0045] The above embodiments and drawings do not limit the product form and style of the present utility model. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present utility model.
