[0033] [First Embodiment]

[0034] As Figures 1-11 shown, a non-powered vertical rain grate for adjusting the flow rate according to the precipitation provided by the first embodiment of the present utility model is shown. As Figures 1-2 shown, it includes a frame 1. A sewage interception component 2 is arranged on the front side of the frame 1, and a rainwater determination device 3 is arranged inside the frame 1. The sewage interception component 2 is connected to the rainwater determination device 3, and the rainwater determination device 3 can correspondingly adjust the flow rate of the sewage interception component 2 according to the precipitation, so as to correspondingly adjust the flow rate of the rain grate according to the precipitation to meet the drainage requirements of urban roads under different rainfall conditions.

[0035] As Figure 3 shown, the sewage interception component 2 in this embodiment includes a plurality of sewage interception frames 21 fixed on the front side of the frame 1. The plurality of sewage interception frames 21 can be arranged at equal intervals and evenly spaced. There is a gap between adjacent sewage interception frames 21, and rainwater can enter the inside of the frame 1 through this gap. Inside the sewage interception frame 21, there is a connecting rod 22 that can move up and down relative to the sewage interception frame 21. The first sewage interception piece 23 and the second sewage interception piece 24 are respectively hinged on the connecting rod 22, so as to drive the first sewage interception pieces 23 and the second sewage interception pieces 24 on both sides to rotate correspondingly through the up and down movement of the connecting rod 22.

[0036] As Figure 3As shown in the figure, sewage interception grooves 211 are respectively formed on both sides of the sewage interception frame 21. The first sewage interception piece 23 and the second sewage interception piece 24 can extend out from both sides of the sewage interception frame 21 or retract towards both sides of the sewage interception frame 21 through the sewage interception grooves 211. Preferably, the sewage interception frame 21 is inclined along both sides of the sewage interception frame 21, and the aperture of the sewage interception frame 21 is such that the first sewage interception piece 23 and the second sewage interception piece 24 can be entirely located inside the sewage interception frame 21. An articulated hole 221 connected to the rainwater determination device 3 is formed at the top of the connecting rod 22 so as to drive the connecting rod 22 to achieve synchronous lifting and lowering movement through the rainwater determination device 3. A plurality of connecting shafts 222 are fixed to the front side of the connecting rod 22, and the first sewage interception piece 23 and the second sewage interception piece 24 on it are movably connected through the plurality of connecting shafts 222.

[0037] As Figure 3 shown, in this embodiment, the first sewage interception piece 23 includes a first connecting portion 231 movably sleeved on the outer periphery of the connecting shaft 222 and a first sewage interception end 232 connected to the first connecting portion 231. The first connecting portion 231 is arranged on the front side of the first sewage interception end 232; the second sewage interception piece 24 includes a second connecting portion 241 movably sleeved on the outer periphery of the connecting shaft 222 and a second sewage interception end 242 connected to the second connecting portion 241. The second connecting portion 241 is arranged on the rear side of the second sewage interception end 242. The first sewage interception end 232 can extend or retract relative to the sewage interception groove 211 through the movable connection between the first connecting portion 231 and the connecting shaft 222, and the second sewage interception end 242 can extend or retract relative to the sewage interception groove 211 through the movable connection between the second connecting portion 232 and the connecting shaft 222. The first connecting portion 231 is arranged on the front side of the first sewage interception end 232, and the second connecting portion 241 is arranged on the rear side of the second sewage interception end 242. Such an arrangement can enable the first sewage interception piece 23 and the second sewage interception piece 24 to be movably installed on the outer periphery of the same connecting shaft 222 at the same time and there will be no relative interference during the movement process.

[0038] Through the above settings, it is achieved that:

[0039] When the connecting rod 22 moves downward inside the sewage interception frame 21 due to its own gravity, through the limiting effect of the sewage interception grooves 211 on both sides of the sewage interception frame 21, the connecting rod 22 drops to the bottom of the corresponding sewage interception groove 211 of the corresponding sewage interception frame 21 and stops. At this time, the first sewage interception piece 23 and the second sewage interception piece 24 movably connected to the connecting rod 22 will extend out from the inside of the corresponding sewage interception groove 211 as the connecting rod drops until the first sewage interception pieces 23 and the second sewage interception pieces 24 on both sides are horizontally and parallel in the opposite direction. At this time, as Figure 4 shown;

[0040] When an upward force pulls the connecting rod to move upward inside the sewage intercepting frame 21, due to the limiting effect of the sewage intercepting grooves 211 on both sides of the sewage intercepting frame 21, the connecting rod 22 rises to the top of the corresponding sewage intercepting groove 211 of the corresponding sewage intercepting frame 21 and stops. At this time, the first sewage intercepting piece 23 and the second sewage intercepting piece 24 movably connected to the connecting rod 22 will retract into the corresponding sewage intercepting groove 211 as the connecting rod rises, until both the first sewage intercepting piece 23 and the second sewage intercepting piece 24 on both sides are completely retracted into the sewage intercepting frame 21. At this time, as Figure 5 shown.

[0041] As Figure 2 shown, the rainwater determination device 3 in this embodiment includes a first shaft 31 and a second shaft 32 movably arranged inside the frame 1 and a rotating shaft (not shown, Figure 2 there is a rotating shaft hole in the middle of the transmission member 34 for cooperation) fixed inside the frame 1. The bottom of the first shaft 31 is hinged with a water tank 33. One end of the transmission member 34 is hinged with the first shaft 31, and the other end is hinged with the second shaft 32. The middle of the transmission member 34 is hinged with the rotating shaft. The second shaft 32 is hinged with the top of the connecting rod 22. Thus, the water tank 33 drives the transmission member 34 to rotate around the middle rotating shaft, and further realizes the lifting action of the connecting rod 22 at the other end.

[0042] As a preference of this embodiment, the mass of the connecting rod 22 is greater than the mass of the water tank 33, so that when there is no rainwater in the water tank 33, the connecting rod 22 can descend inside the sewage intercepting frame 21 due to its own gravity being greater than that of the water tank 33; while the mass of the connecting rod 22 is less than the mass of the water tank 33 and the rainwater at the preset liquid level inside it, so that when the rainwater in the water tank 33 reaches the preset liquid level, the connecting rod 22 can be pulled to rise inside the sewage intercepting frame 21 due to the mass of the water tank and the rainwater at the preset liquid level inside it.

[0043] The bottom of the water tank 33 is provided with an outflow hole 331, so that the rainwater inside the water tank 33 can slowly flow out through the outflow hole 331 after the rainfall ends.

[0044] The specific working process of this embodiment is as follows:

[0045] As Figures 6-7 shown, in sunny or light rain weather, the road rainwater flows into the inside of the frame 1 through the gap between the sewage intercepting components 2. Because the water level inside the frame 1 does not rise to the position of the water tank 33, the water tank 33 only has its own downward gravity. And since the mass of the water tank 33 is less than the mass of the connecting rod 22, at this time, the connecting rod 22 is at the bottom of the corresponding sewage intercepting groove 211 inside the sewage intercepting frame 21 due to its own gravity. At this time, the first sewage intercepting piece 23 and the second sewage intercepting piece 24 movably connected to the connecting rod 22 will extend out of the corresponding sewage intercepting groove 211 as the connecting rod falls, so as to intercept fine pollutants in the gap;

[0046] As Figures 8-9As shown in the figure, during heavy rain or rainstorm weather, road rainwater flows into the interior of the frame 1 through the gaps between the sewage interception components 2. Since the water level inside the frame 1 gradually rises until it enters the interior of the water tank 33, under the combined downward gravity of the water tank 33 itself and the preset liquid level rainwater inside the water tank 33, the first shaft 31 is driven to move downward. At the same time, the first shaft 31 drives the transmission member 34 to rotate counterclockwise, and the other end of the transmission member 34 drives the second shaft 32 to pull the connecting rod 22 to rise, thereby realizing the upward movement of the connecting rod 22 inside the sewage interception frame 21 until it moves to the top of the corresponding sewage interception groove 211. At this time, the first sewage interception piece 23 and the second sewage interception piece 24 movably connected to the connecting rod 22 will completely retract into the corresponding sewage interception groove 211 as the connecting rod rises, thereby increasing the gap between the sewage interception components 2 to increase the flow rate and obtain higher drainage capacity;

[0047] As Figures 10-11 As shown in the figure, after the rainfall ends, the rainwater inside the water tank 33 slowly flows out through the bottom outflow hole 331, so that the rainwater inside the water tank 33 slowly flows out until it is completely drained. At this time, the water tank 33 cannot drive the connecting rod 22 to move downward through the transmission member 34 under its own gravity, and the connecting rod 22 moves downward inside the sewage interception frame 21 under its own gravity until it is located at the bottom of the corresponding sewage interception groove 211. During this process, the first sewage interception piece 23 and the second sewage interception piece 24 movably connected to the connecting rod 22 will gradually extend out of the corresponding sewage interception groove 211 as the connecting rod falls.

[0048] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.
