Description

Technical Field

[0001] This utility model relates to the field of rainwater harvesting technology, specifically a device for rainwater diversion from elevated bridges. Background Technology

[0002] An elevated bridge, also known as an overpass, is a type of bridge. It specifically refers to a bridge supported by high-rise towers or pillars, spanning valleys, rivers, roads, or other low-lying obstacles, resting on a series of narrow reinforced concrete or masonry arches. With urban development, traffic congestion and dense building density, coupled with the difficulty of widening streets, have led to the use of elevated bridges to alleviate traffic density and improve transportation efficiency. Furthermore, elevated bridges are used on intercity highways or railways to avoid at-grade intersections with other lines, save land, and reduce roadbed settlement.

[0003] In the construction of rail transit, rainwater collection and utilization at elevated stations can effectively limit rainwater discharge and loss from the bridge surface and control rainwater runoff pollution around the elevated line. However, as rainwater falls to the ground, dust in the air and debris on the ground can pollute the rainwater. Therefore, without filtration or other treatment, the collected rainwater has poor water quality. Utility Model Content

[0004] This invention provides a device for diverting rainwater from elevated bridges to solve the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for rainwater diversion from elevated bridges, comprising a housing, a rainwater inlet pipe on one side of the housing, a rainwater overflow pipe on the other side of the housing, a fixed frame fixedly connected to the inner cavity of the housing, the end of the rainwater inlet pipe extending into the inner cavity of the fixed frame, a through groove at the bottom of the fixed frame, a filter frame detachably provided at the through groove, filter holes evenly provided on the four outer walls of the filter frame, a float box installed in the inner cavity of the housing below the fixed frame, a guide rod fixedly connected to one inner wall of the float box, a large float inside the float box, a U-shaped lifting rod with an arm movable through the guide rod fixedly connected to the top of the large float, a diversion pipe at the bottom of the housing, a blocking float connected to one end of the lifting rod in the inner cavity of the diversion pipe, and an annular stop block cooperating with the blocking float at the top of the inner wall of the diversion pipe.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4This utility model discloses a device for rainwater diversion from elevated bridges, comprising a housing 1, a rainwater inlet pipe 2 on one side of the housing 1, and a rainwater overflow pipe 14 on the other side of the housing 1. A fixing frame 3 is fixedly connected to the inner cavity of the housing 1. The end of the rainwater inlet pipe 2 extends into the inner cavity of the fixing frame 3. A through groove 16 is formed at the bottom of the fixing frame 3. A filter frame 4 is detachably provided at the through groove 16. Filter holes are evenly formed on the four outer walls of the filter frame 4. A float box 5 is installed in the inner cavity of the box 1 below the fixed frame 3. A guide rod 7 is fixedly connected to one side of the inner wall of the float box 5. A large float 8 is provided in the float box 5. A U-shaped lifting rod 10 with one arm movable through the guide rod 7 is fixedly connected to the top of the large float 8. A diversion pipe 6 is provided at the bottom of the box 1. A blocking float 11 connected to one end of the lifting rod 10 is provided in the inner cavity of the diversion pipe 6. An annular stop block 9 that cooperates with the blocking float 11 is provided at the top of the inner wall of the diversion pipe 6.

[0019] The overflow pipe 6 is connected to the corresponding sewage pipe, and the rainwater overflow pipe 14 is connected to the corresponding rainwater collection facilities.

[0020] The top height of the fixed frame 3 is higher than the top height of the rainwater overflow pipe 14.

[0021] Specifically, the bottom side of the float box 5 is provided with a seepage hole 12 that communicates with the diversion pipe 6.

[0022] In this implementation scheme, rainwater enters the fixed frame 3 through the rainwater inlet pipe 2. After being filtered by the filter frame 4, part of the rainwater falls into the float box 5 and part falls on the bottom inner wall of the box body 1. It is discharged through the diversion pipe 6. The water in the float box 5 can be discharged to the diversion pipe 6 through the seepage hole 12.

[0023] When the flow rate of water entering the float box 5 is equal to the flow rate of water discharged from the seepage hole 12, the water level in the float box 5 rises, and the large float 8 rises accordingly. It also drives the sealing float 11 above the lifting rod 10. The sealing float 11, together with the baffle 9, blocks the diversion pipe 6. At this time, the water in the tank 1 cannot be discharged from the diversion pipe 6. The water level in the float box 5 and the tank 1 continues to rise. When the water level in the tank 1 rises to the level of the rainwater overflow pipe 14, the rainwater is discharged through the rainwater overflow pipe 14 and collected. The rainwater collected by the rainwater overflow pipe 14 is relatively clean.

[0024] The height of the seepage hole 12 is lower than the height of the bottom of the baffle 9. That is, when the diversion pipe 6 is blocked, the seepage hole 12 can still complete the drainage operation. When the water flow rate entering the float box 5 is less than the water flow rate discharged from the seepage hole 12, the water level in the float box 5 drops, the large float 8 drops accordingly, and drives the blocking float 11 to no longer block the diversion pipe 6. At this time, the water in the box 1 located below the rainwater overflow pipe 14 can be discharged.

[0025] Specifically, the filter frame 4 is located above the float box 5, and the float box 5 is located on one side of the bottom of the filter frame 4.

[0026] In this embodiment, the float box 5 is located on the left side of the bottom of the filter frame 4. That is, some of the rainwater falling through the filter frame 4 falls into the float box 5 and some falls outside the float box 5.

[0027] Specifically, the inner cavity of the housing 1 is equipped with a filter screen 15 to block the rainwater overflow pipe 14.

[0028] In this embodiment, rainwater passing through the rainwater overflow pipe 14 can be filtered by the filter screen 15.

[0029] Specifically, the top of the filter frame 4 has a protruding edge 13, the filter frame 4 passes through the through groove 16, and the protruding edge 13 of the filter frame 4 rests on the bottom inner wall of the fixed frame 3.

[0030] A handle 17 is fixedly connected to the raised edge 13.

[0031] In this embodiment, the top of the fixed frame 3 is open, and the filter frame 4 can be removed from the fixed frame 3 by means of the handle 17.

[0032] In summary, this device for rainwater diversion from elevated bridges can filter out large debris in rainwater during the rainwater collection and utilization process, and divert the initial rainwater. When the rainwater volume increases, the diversion pipe 6 is blocked, the water level in the tank 1 rises, and the relatively clean rainwater above can be collected and utilized through the rainwater overflow pipe 14.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
