Description

Technical Field

[0001] This utility model relates to the field of municipal drainage technology, and more specifically, to a rainwater interception device. Background Technology

[0002] Existing stormwater interception devices, including grates and interception boxes, are the front-end collection facilities of urban stormwater pipe network systems. They are widely distributed in stormwater inlets in areas such as roads, squares, and residential areas. Stormwater interception devices are the first line of defense in the stormwater interception system, and their main function is to coarsely filter surface stormwater runoff and introduce it into the underground pipe network.

[0003] However, after prolonged use, existing rainwater interception devices tend to accumulate debris such as leaves, branches, and gravel at the bottom of the interception box, which can easily clog the filter holes, affecting the device's drainage efficiency and potentially causing rainwater to overflow in reverse. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides a rainwater interception device to solve the problem that after long-term use, the existing rainwater interception devices are prone to clogging of the filter holes due to the even distribution of garbage such as leaves, branches, and gravel at the bottom of the interception box, which affects their drainage efficiency.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a rainwater interception device, including an interception well, a bracket wall at the top of the interception well, a rainwater grate on the bracket wall, an interception box at the bottom of the bracket wall, and a collection box fixedly installed on both sides of the bottom of the interception box. First filter holes are provided on the surfaces of both the interception box and the collection box. The collection box has a U-shaped cross-section with its opening facing upwards. Several arc-shaped frames are evenly spaced between the tops of two collection boxes, with the openings of the arc-shaped frames facing downwards.

[0006] Preferably, the bottom of the intercepting well is provided with two drainage outlets.

[0007] Preferably, the distance between two adjacent arc-shaped frames is equal to the diameter of the first filter hole and smaller than the diameter of the rain grate, and the bracket wall is aligned with the inner cavity of the intercepting tank.

[0008] Preferably, the intercepting tank is provided with a sludge-dispensing component, which includes a cylindrical shaft frame rotatably mounted on the intercepting tank. A water filter cylinder is fixedly mounted on the cylindrical shaft frame, and the surface of the water filter cylinder is evenly provided with second water filter holes. Two actuating rods are fixedly connected to both ends of the cylindrical shaft frame, and a water-dispensing groove is fixedly mounted at the bottom end of the actuating rods. A sludge-dispensing frame is provided on the water filter cylinder.

[0009] Preferably, the axis of the cylindrical frame, the filter cylinder and the arc frame are aligned, the diameter of the second filter hole is equal to the diameter of the first filter hole, and the second filter hole and the arc frame are staggered.

[0010] Preferably, there are two water-dispensing troughs, located below the two sludge collection boxes respectively, and the opening of the water-dispensing trough is larger than the horizontal cross-section of the sludge collection box. The sludge-dispensing frame is arranged in a comb-like structure, and the sludge-dispensing frame is staggered with the arc-shaped frame.

[0011] Preferably, it also includes an emergency drainage component, which includes a limiting slide groove, a first frame, a second frame, and a debris-blocking rod. The limiting slide groove is formed inside the bracket wall. The upper and lower ends of the debris-blocking rod are fixedly connected to the first frame and the second frame, respectively. Both the first frame and the second frame can slide up and down along the limiting slide groove. A vertical return spring is provided in the limiting slide groove. The upper and lower ends of the return spring are fixed to the limiting slide groove and the first frame, respectively.

[0012] Preferably, there are several of each of the debris-blocking rods and the return spring, which are evenly distributed, and the distance between two adjacent debris-blocking rods is greater than the diameter of the first filter hole.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This invention, through the design of the first filter hole and the arc-shaped frame, allows garbage to flow directly into the collection box with rainwater, or fall onto the arc-shaped frame and slide down along the arc of the frame to be collected into the collection box. This concentrates the garbage and avoids large areas of garbage blockage, which would affect the overall drainage effect of the device.

[0014] This invention utilizes a debris-discharging component. When there is a large amount of rainwater in one side of the water-discharging trough, it causes the debris-discharging frame on the filter cylinder to deflect, pushing the debris on the arc-shaped frame into the debris collection box on the same side, reducing the rainwater flow. Furthermore, because the water-discharging trough is tilted and rainwater is poured out, the rainwater flow on the other side increases. Similarly, the debris on the arc-shaped frame is pushed towards the debris collection box on the other side, thus preventing debris from accumulating on the arc-shaped frame and ensuring good drainage performance of the device.

[0015] This utility model, through the setting of an emergency drainage component, uses the accumulation of rainwater in the intercepting box and the collection box to make it heavier, which can drive the first frame, the second frame, and the debris barrier to slide down. Rainwater will overflow from the intercepting box and be discharged through the gaps in the debris barrier, retaining a certain degree of interception of large-volume garbage. At the same time, it prioritizes the overall drainage effect of the device and prevents rainwater from overflowing from the rain grate. Attached Figure Description

[0018] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0019] As attached Figure 1 To be continued Figure 2 This utility model provides a rainwater interception device, including an interception well 1. A bracket wall 2 is provided at the top of the interception well 1, and a rainwater grate 3 is provided on the bracket wall 2. An interception box 4 is provided below the bracket wall 2. Rainwater is intercepted for the first time by the rainwater grate 3 and then flows into the interception box 4 through the bracket wall 2. Sewage collection boxes 5 are fixedly installed on both sides of the bottom of the interception box 4. First filter holes 6 are provided on the surface of both the interception box 4 and the sewage collection boxes 5. The sewage collection boxes 5 have a U-shaped cross-section. The opening of the sludge collection box 5 faces upward. Several arc-shaped frames 7 are evenly spaced between the tops of the two sludge collection boxes 5. The openings of the arc-shaped frames 7 face downward. Two drain outlets 8 are provided at the bottom of the intercepting well 1. The drain outlets 8 are connected to the underground drainage pipe. The distance between two adjacent arc-shaped frames 7 is equal to the diameter of the first filter hole 6 and smaller than the diameter of the rain grate 3. The first filter hole 6 and the arc-shaped frames 7 can intercept rainwater for the second time and can intercept and collect smaller garbage. The bracket wall 2 is aligned with the inner cavity of the intercepting box 4.

[0020] Specifically, when the rainfall is light, the garbage passes through the rain grate 3, the first filter hole 6, and the arc-shaped frame 7 in sequence with the rainwater for two filtrations. After the garbage falls onto the arc-shaped frame 7, it will slide down along the arc of the frame 7 and be collected in the sludge collection box 5, so that the garbage is relatively concentrated and avoids a large area of ​​garbage blockage, which would affect the overall drainage effect of the device.

[0021] Further embodiments, such as Figure 2As shown, a sludge-discharging assembly 9 is provided on the sludge interception box 4. The sludge-discharging assembly 9 includes a cylindrical shaft frame 91, which is rotatably mounted on the sludge interception box 4. A water filter cylinder 92 is fixedly mounted on the cylindrical shaft frame 91. Second water filter holes 93 are evenly opened on the surface of the water filter cylinder 92. Two actuating rods 94 are fixedly connected to both ends of the cylindrical shaft frame 91. A water-discharging groove 95 is fixedly installed at the bottom end of the actuating rod 94. A sludge-discharging frame 96 is provided on the water filter cylinder 92. The axis of the cylindrical shaft frame 91, the water filter cylinder 92 and the arc frame 7 are aligned. The diameter of the second water filter hole 93 is equal to the diameter of the first water filter hole 6, and the second water filter hole 93 and the arc frame 7 are staggered. There are two water-discharging grooves 95, which are located below the two sludge collection boxes 5 respectively. The opening of the water-discharging groove 95 is larger than the horizontal cross section of the sludge collection box 5. The sludge-discharging frame 96 is arranged in a comb-like structure and is staggered with the arc frame 7.

[0022] Specifically, with prolonged use, a certain amount of debris may accumulate on the arc-shaped frame 7. At this time, due to the different degrees of blockage of the first filter holes 6 on both sides by the debris, the flow rate of rainwater discharged from the two collection boxes 5 will change. When there is more rainwater in one side of the water channel 95, it will cause the debris-discharging frame 96 on the filter cylinder 92 to deflect, pushing the debris on the arc-shaped frame 7 into the collection box 5 on the same side, reducing the rainwater flow. Furthermore, since the water channel 95 is tilted and rainwater is poured out, the rainwater flow on the other side increases. Similarly, the debris on the arc-shaped frame 7 is pushed towards the collection box 5 on the other side, thereby preventing the debris from accumulating on the arc-shaped frame 7 and ensuring good drainage of the device. In the above process, the debris-discharging frame 96 does not need to swing back and forth frequently to push the debris. It is sufficient if the two water channels 95 become unbalanced a few times during long-term use.

[0023] Further embodiments, such as Figures 3 to 4 As shown, it also includes an emergency drainage component 10, which includes a limiting slide 101, a first frame 102, a second frame 103, and a debris-blocking bar 104. The limiting slide 101 is opened in the bracket wall 2. The upper and lower ends of the debris-blocking bar 104 are fixedly connected to the first frame 102 and the second frame 103, respectively. The first frame 102 and the second frame 103 can slide up and down along the limiting slide 101. A vertical return spring 105 is provided in the limiting slide 101. The upper and lower ends of the return spring 105 are fixed to the limiting slide 101 and the first frame 102, respectively. There are several debris-blocking bars 104 and return springs 105, which are evenly distributed. The distance between two adjacent debris-blocking bars 104 is greater than the diameter of the first filter hole 6.

[0024] Specifically, when there is heavy rainfall, the amount of rainwater discharged from the intercepting tank 4 and the collection box 5 is less than the amount of rainwater flowing in. As a result, the rainwater in the intercepting tank 4 and the collection box 5 accumulates and becomes heavy, which causes the first frame 102, the second frame 103, and the baffle bar 104 to slide down. The return spring 105 is stretched, and then the rainwater overflows from the intercepting tank 4 and is discharged through the gaps in the baffle bar 104. This retains a certain degree of interception of large-volume garbage, while prioritizing the overall drainage effect of the device and preventing rainwater from overflowing from the rain grate 3.
