Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rainwater well drainage, in particular to a rainwater grate for preventing waterlogging. Background Art
[0002] Many cities often experience varying degrees of waterlogging after heavy rainfall, which seriously affects citizens' travel and the city's image, and also creates certain safety hazards. One of the main reasons for waterlogging is that the rainwater grate has limited water-passing capacity or the rainwater grate is blocked by debris such as leaves.
[0003] At present, in order to solve the problem of rainwater grate blockage and clean up debris such as leaves, operating units either spend a lot of manpower to repeatedly clean up on site; or use rainwater grates with sensors and power devices to achieve automatic lifting and opening to reduce the workload of manpower. However, there are problems such as time-consuming, labor-intensive or high cost, and easy damage. Therefore, a cheap and reliable structure is needed that can automatically open the rainwater grate and increase the flow area in the case of waterlogging. Utility Model Content
[0004] In view of the deficiencies in the prior art, the utility model provides a rainwater grate for preventing waterlogging. In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0005] A rainwater grate for preventing waterlogging comprises a rainwater well and a grate covering a water inlet of the rainwater well, wherein the rainwater well is provided with a water outlet, a box body and a bracket, wherein the box body is arranged on a side of the rainwater well on a sidewalk, the bottom of the box body is communicated with the rainwater well, a plurality of vertical grooves are provided on the side walls of the box body adjacent to the rainwater well, a floating block which moves vertically in the box body is arranged in the box body, the bracket is horizontally slidably connected in the groove, one end of the bracket is fixedly connected to the grate, and the other end is fixedly connected to the floating block.
[0006] Furthermore, grilles are fixedly connected around the grate, and the grilles are arranged downward and slidably connected to the wall of the rainwater well.
[0007] Furthermore, the box body is configured to be square, and the floating block is configured to be in a shape corresponding to the box body and is slidably connected to the box body.
[0008] Furthermore, a plurality of water holes are provided on the floating block.
[0009] Furthermore, a plurality of drainage holes are provided on the side of the box body that is higher than the grate.
[0010] Furthermore, the bracket is arranged in a "J" shape.
[0011] Compared with the prior art, the utility model has the following beneficial effects:
[0012] According to the principle of buoyancy and connectivity, the water accumulated in the waterlogging is introduced into a box with a floating block. The buoyancy of the water is used to automatically lift the rainwater grate by moving the floating block upward, increasing the side flow area and accelerating the discharge of the accumulated water. After the accumulated water is discharged, the water in the box is automatically discharged into the rainwater well, and the float moves downward to automatically restore the rainwater grate. This structure is a simple and practical rainwater grate for preventing waterlogging that does not require external power, greatly reducing the operating labor cost and reducing the urban inner river.

[0016] In the above drawings: rainwater well 1, grate 2, water outlet 3, box body 4, bracket 5, groove 6, floating block 7, grille 8, water hole 9, drainage hole 10. DETAILED DESCRIPTION
[0017] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0018] Please refer to Figure 1 , Figure 2 As shown, a rainwater grate for preventing waterlogging includes a rainwater well 1 and a grate 2 covering the water inlet of the rainwater well 1, wherein the rainwater well 1 is provided with a water outlet 3, and further includes a box 4 and a bracket 5. The box 4 is arranged on the side of the rainwater well 1 located on the sidewalk, and the bottom of the box 4 is communicated with the rainwater well 1. A plurality of vertical grooves 6 are provided on the side walls adjacent to the rainwater well 1. A floating block 7 that moves vertically in the box 4 is provided in the box 4. The bracket 5 is horizontally slidably connected in the groove 6, and one end of the bracket 5 is fixedly connected to the grate 2, and the other end is fixedly connected to the floating block 7.
[0019] Working principle: A rainwater well 1 connected to the sewer is installed at the rainwater inlet, and a box 4 is set closely to it, and the box 4 is connected to the rainwater well 1. A rainwater grate 2 is covered on the rainwater well 1, which can move up and down within a certain range. A floating block 7 is placed in the box 4, which can move up and down under the buoyancy of water according to the water level in the box 4. The bracket 5 passes through the side of the box 4, and connects and fixes the float and the rainwater grate 2 respectively to achieve synchronous up and down movement. When the water accumulation in this part exceeds a certain height, the accumulated water flows into the box 4 through the groove 6 set on the side of the box 4 or enters the box 4 from the channel connected to the rainwater well 1. When the inflow water exceeds the outflow water from the outlet 3, the water level in the box 4 rises, and the buoyancy drives the floating block 7 to move upward, and then drives the rainwater grate 2 to move upward through the bracket 5, increasing the flow area and accelerating the discharge of the accumulated water. After the accumulated water is discharged, the accumulated water in the box body 4 flows into the rainwater well 1 and is discharged. The water level in the box body 4 drops, and the buoy moves downward to drive the rainwater grate 2 downward until it returns to its original state.
[0020] In this embodiment, please refer to Figure 1 As shown, a grille 8 is fixedly connected around the grate 2, and the grille 8 is arranged downward and slidably connected to the wall of the rainwater well 1. By arranging the grille 8, after the grate 2 rises, the grille 8 can prevent debris from entering the sewer to avoid clogging.
[0021] In this embodiment, please refer to Figure 2 As shown, the box body 4 is arranged in a square shape, and the floating block 7 is arranged in a shape corresponding to the box body 4 and is slidably connected with the box body 4. The box body 4 is used to limit the floating block 7, so that the floating block 7 can be lifted and lowered more smoothly.
[0022] In this embodiment, please refer to Figure 2 As shown, a plurality of water holes 9 are provided on the floating block 7, so that the water entering the box body 4 from above the floating block 7 can flow into the bottom of the floating block 7, thereby ensuring the normal lifting of the floating block 7.
[0023] In this embodiment, please refer to Figure 1 As shown, a plurality of drainage holes 10 are provided on the side of the box body 4 which is higher than the grate 2. It is convenient for water to enter the box body 4 from the side of the box body 4.
[0024] In this embodiment, please refer to Figure 2 As shown, the bracket 5 is arranged in a "X" shape. The bracket 5 surrounds the two sides of the side plates of the box body 4, so that the bracket 5 can be moved in a tight straight direction and is easy to use.
[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
