TECHNICAL FIELD

[0001] The present application relates to the technical field of urban road drainage, in particular to a button type adjustable overflow type rainwater bucket. BACKGROUND

[0002] At present, the design measures of the sponge city usually arrange the sunken green land around the road, and the sunken green land refers to a public green land with a lower elevation than the surrounding road surface, also known as low-lying green land. The concept is to use open space to collect and store rainwater, which has the functions of supplementing groundwater, regulating runoff, retarding flood and reducing runoff pollutants, and is helpful for urban road drainage.

[0003] During heavy rain, the rainwater storage speed of the sunken green land will be greater than the rainwater penetration speed, which will cause the rainwater to flow to the road surface, so an overflow type rainwater well is usually installed at the sunken green land, and the rainwater that cannot be timely penetrated in the sunken green land will flow into the pipeline for rainwater collection through the overflow type rainwater well. The space in the sunken green land lower than the overflow type rainwater well is the water storage space of the sunken green land.

[0004] However, the traditional overflow type rainwater well has the following disadvantages: 1. The actual water storage capacity of the sunken green land is prone to have a large deviation due to construction deviation and later adjustment; 2. The overflow type rainwater well is difficult to adjust the water storage capacity of the sunken green land by adjusting the height thereof due to the concrete masonry, and the workload of the later rework adjustment is large; 3. The well surface diameter of the overflow type rainwater well is large, which occupies a large area for the small area of the sunken green land, and affects the appearance. SUMMARY

[0018] By adopting the above technical scheme, when the amount of rainwater in the water storage groove exceeds the maximum water storage capacity of the water storage space, the rainwater will flow into the overflow space from the spacing between the overflow pipe and the groove bottom of the water storage groove, and then be discharged to the water collecting pipe through the drain hopper; at the same time of the rainwater gathering in the water storage groove, the garbage in the sunken green land will float in the rainwater and mainly float at the top of the rainwater, during the drainage process, the rainwater at the bottom is preferentially discharged, and the rainwater at the top is difficult to enter the overflow space above the overflow pipe, so that the probability of the garbage floating in the rainwater blocking the drain hopper can be reduced.

[0023] Optionally, the top of the overflow pipe has an intercepting portion, the intercepting portion is arranged obliquely, and the intercepting portion is an obliquely downward end close to one end of the first drain pipe.

[0024] By adopting the technical scheme, the intercepting portion can intercept rainwater at the top, and prevent the rainwater from passing over the overflow pipe and entering the overflow space. Meanwhile, when the rainwater washes the intercepting portion, the intercepting portion can guide the rainwater to flow downward, so that the rainwater is more likely to enter the overflow space from below the overflow pipe.

[0025] Optionally, the outer side of the overflow pipe is provided with an intercepting assembly for intercepting garbage, and the intercepting assembly comprises a plurality of intercepting pieces.

[0026] By adopting the technical scheme, during the drainage process, the rainwater flows towards the overflow-type rainwater head, and moves together with the garbage. After the garbage contacts the overflow pipe, the intercepting pieces can intercept and retain the garbage. After the rainwater penetrates, the garbage can still be retained on the intercepting pieces, so that the staff can clean up the garbage conveniently.

[0027] In summary, the present application has at least one of the following beneficial effects:

[0028] 1. The size of the water storage space can be adjusted by the adjusting assembly according to the water penetration capacity of the sunken green land, so that the sunken green land can penetrate rainwater into the ground in time, and the excess water can be discharged to the water collecting pipe through the drain pipe in time, thereby reducing the probability of rainwater overflowing onto the road surface.

[0038] The application discloses a button type adjustable overflow rainwater bucket.

[0039] Example 1:

[0040] With reference to Figure 1 , the overflow rainwater bucket is installed on the sunken green land 1, the sunken green land 1 has a water storage groove 11 for storing rainwater, and both sides of the sunken green land 1 are urban roads 2. The water storage groove 11 can store rainwater when it rains, reduce the water accumulation on the road surface, and the rainwater in the water storage groove 11 can penetrate into the ground. The overflow rainwater bucket comprises a drainage bucket 3, a drainage pipe fitting 4 and a water collecting pipe 5, the water collecting pipe 5 is buried in the ground, and the water collecting pipe 5 is distributed in a network shape in the ground.

When it rains, rainwater is stored in the water storage groove 11, and under the penetration of the sunken green land 1, the rainwater penetrates into the ground; rainwater exceeding the penetration capacity of the sunken green land 1 can be discharged into the water collecting pipe 5 through the drainage bucket 3 and the drainage pipe fitting 4, effectively reducing the probability of rainwater flowing out to the road surface, and also allowing the water accumulation on the road surface to flow in, reducing the runoff on the road surface.

[0041] With reference to Figure 1 and Figure 2The drain pipe 4 comprises a first drain pipe 41 and a second drain pipe 42.

[0042] The part of the drain hopper 3 below the drain holes 31 is the water storage space 12 of the sunken green land 1. The rainwater exceeding the water storage space 12 is drained through the drain holes 31.

[0043] Referring to Figure 1 and Figure 2 , the first drain pipe 41 and the second drain pipe 42 are also provided with an adjusting assembly 7 for adjusting the relative position relationship between the first drain pipe 41 and the second drain pipe 42. The adjusting assembly 7 can change the distance between the drain hopper 3 and the bottom of the water storage groove 11, so as to change the size of the water storage space 12.

[0044] Referring to Figure 2 and Figure 3 , the adjusting assembly 7 comprises a connecting belt 71. The connecting belt 71 can be stretched and contracted along the length direction.

The first drain pipe 41 is communicated with the second drain pipe 42 through the connecting belt 71. In the embodiment, the connecting belt 71 is synchronously stretched and contracted. After the same degree of stretching and contraction occurs at each position of the connecting belt 71, the overall length of the connecting belt 71 changes. The connecting belt 71 is preferably a toothed stretchable stainless steel belt.

[0045] The adjusting assembly 7 further comprises a main body 74, a positioning member 72 for fixing the stretching and contraction state of the connecting belt 71, and a button 73 for controlling the working of the positioning member 72.

The length direction of the positioning member 72 is consistent with the sliding direction thereof, one end of the length direction of the positioning member 72 is fixedly connected with the button 73, and the other end of the length direction of the positioning member 72 is in wedge-shaped structure. After the button 73 is pressed to slide towards the direction close to the connecting belt 71, the button 73 drives the positioning member 72 to slide so that one end of the wedge-shaped structure abuts against the connecting belt 71, and the cooperation between the wedge-shaped structure and the connecting belt 71 improves the friction therebetween, thereby limiting the expansion and contraction of the connecting belt 71.

[0048] The main body is further provided with a plurality of glass beads screws 75, and a plurality of clamping grooves 731 matched with the glass beads screws are formed in the button 73. When the positioning member 72 positions the connecting belt 71, the position of the button 73 in the second sliding groove 742 is also fixed by the plurality of glass beads screws.
