Description

Technical Field

[0001] The utility model relates to the technical field of bridge road drainage channels, in particular to an anti-blocking structure for a municipal bridge road drainage channel. Background Technique

[0002] Bridge drainage is an important part of bridge engineering, which is directly related to the safety and service life of the bridge. The main purpose of the bridge drainage system is to quickly drain the water on the bridge surface, prevent rainwater from accumulating on the bridge surface and seeping into the beam body, thereby affecting the durability of the bridge. When designing a bridge, longitudinal and transverse slopes need to be set on the bridge surface, and a certain number of drainage pipes need to be set to form a complete drainage system. With the continuous development of bridge drainage, various anti-blocking devices for drainage channels have emerged, such as an anti-blocking structure for a municipal bridge road drainage channel.

[0003] After retrieval, an anti-blocking external device for a municipal bridge road drainage channel in a Chinese utility model patent with the patent number CN202122343963.X includes a first connecting pipe. One side of the first connecting pipe is fixedly connected with a connecting elbow. One side of the connecting elbow is fixedly connected with a second connecting pipe. A filtering mechanism is movably connected inside the second connecting pipe. One side of the first connecting pipe away from the connecting elbow is fixedly connected with a cleaning mechanism. The advantages of the utility model are as follows: by setting the filtering mechanism, when in use, the water inlet filter plate is retained on the surface of the road surface, so as to avoid the filter mesh cover affecting the normal passage of vehicles or pedestrians, and it is also convenient for the staff to quickly install and disassemble the filter mesh cover, so as to facilitate its cleaning. By setting the cleaning mechanism, the purpose of facilitating the user to clean the filter cylinder is achieved, and the sundries can be filtered again through the water permeable holes and convex blocks. The structure is simple and easy to use. Although this device can filter the sundries of flowers and plants, since the filter mesh cover is arranged inside the installation cylinder, the filtered sundries are stuck between the water inlet filter plate and the filter mesh cover. After heavy rain, if the filter mesh cover is not cleaned in time, the pipeline will be blocked. Therefore, an anti-blocking structure for a municipal bridge road drainage channel that can collect the sundries after filtration and effectively avoid the pipeline being blocked by sundries is proposed.

Specific implementation manners

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-4 , a blockage prevention structure for a municipal bridge road drainage channel in this embodiment, includes a main drain pipe 1, a water inlet pipe 2 is arranged at the top of the main drain pipe 1: a cleaning mechanism 3 is arranged outside the main drain pipe 1;

[0021] The cleaning mechanism 3 includes a main filter screen 301, a collection pipe 302, a collection box 303, a collection frame 304, an auxiliary filter screen 305, an auxiliary drain pipe 306, a three-way connecting pipe 307 and an elbow pipe 308. The main filter screen 301 is arranged inside the main drain pipe 1, the collection pipe 302 is fixedly installed on the left side of the main drain pipe 1, the collection box 303 is fixedly installed at the bottom of the collection pipe 302, the collection frame 304 is arranged inside the collection box 303, the auxiliary filter screen 305 is fixedly installed at the bottom of the collection frame 304, the auxiliary drain pipe 306 is fixedly installed at the bottom of the collection box 303, the right side of the auxiliary drain pipe 306 is fixedly connected to the three-way connecting pipe 307, and the bottom of the three-way connecting pipe 307 is fixedly connected to the elbow pipe 308.

[0022] In the case implementation, a clockwork spring 5 is arranged inside the collection pipe 302, and a baffle 501 is fixedly connected to the outside of the clockwork spring 5. By arranging the clockwork spring 5 and the baffle 501, when there is no debris in the rainwater, most of the rainwater can fall from the baffle 501 through the main filter screen 301. By arranging the clockwork spring 5, when debris accumulates on the upper end of the main filter screen 301, through the inclined main filter screen 301, the debris can be pressed against the baffle 501 to the left and enter the collection pipe 302, so as to collect the debris and prevent the main drain pipe 1 from being blocked.

[0023] In the case implementation, a block 6 is fixedly installed on the right side of the collection frame 304, and a card slot 601 adapted to the block 6 is opened inside the collection box 303. By arranging the block 6 and the card slot 601, the position of the collection frame 304 can be restricted, so that the connection port 8 is aligned with the collection pipe 302.

[0024] In the case implementation, a movable door 7 is hinged on the left side of the collection box 303, and a key lock 701 is arranged outside the movable door 7. By arranging the movable door 7 and the key lock 701, the movable door 7 can be opened regularly to take out the collection frame 304 to clean the debris. The main drain pipe 1 is relatively long and is fixedly installed on the side of the bridge, so that the movable door 7 outside the collection box 303 can be opened for processing, and the elbow pipe 308 is connected to the urban drainage system.

[0025] In the case implementation, a connection port 8 is opened at the top of the collection frame 304, and the collection pipe 302 is connected to the collection frame 304 through the connection port 8. By arranging the connection port 8, the debris inside the collection pipe 302 can fall into the collection frame 304 through the connection port 8.

[0026] During implementation, the following steps are carried out for operation:

[0027] 1) First, when the bridge needs to drain water, the rainwater enters the main drain pipe 1 from the manhole cover 4, and large debris is isolated outside.

[0028] 2) Then, the rainwater with grass and debris is filtered through the main filter screen 301, and the rainwater continues to fall in the pipeline. After the debris accumulates, it presses the baffle 501 installed with the clockwork spring 5 and rushes into the collection pipe 302 to fall into the inside of the collection frame 304.

[0029] 3) Then, the rainwater is filtered through the auxiliary filter screen 305 and merged into the main drain pipe 1 through the three-way connecting pipe 307.

[0030] 4) Finally, it is discharged from the elbow pipe 308, and the movable door 7 is opened regularly to take out the collection frame 304 to clean the impurities.

[0031] In summary, for the anti-blocking structure of the drainage channel of the municipal bridge road, by setting up the cleaning mechanism 3, when the bridge needs to drain water, rainwater enters the main drain pipe 1 from the manhole cover 4, and large sundries are isolated outside. Then, the rainwater, plants and sundries pass through the main filter screen 301 for filtration. The rainwater continues to fall in the pipeline. After the sundries accumulate, the baffle 501 installed with the spring 5 is pressed to rush leftward into the collection pipe 302 and fall into the interior of the collection frame 304. The rainwater is filtered again through the auxiliary filter screen 305 and then incorporated into the main drain pipe 1 through the tee connection pipe 307 and discharged from the elbow pipe 308. Then, the movable door 7 is opened regularly to take out the collection frame 304 to clean the impurities. The cleaning mechanism 3 can collect the sundries after filtration and effectively avoid the blockage of the pipeline by sundries.
