Description

Technical Field

[0001] This utility model belongs to the field of bridge drainage technology, specifically an anti-clogging device for bridge drainage channels. Background Technology

[0002] The bridge deck is blocked by guardrails on both sides. Currently, the guardrails are made of cast concrete, which increases the overall impact resistance and can effectively protect vehicles from breaking through the guardrails in the event of a collision. However, this type of cast concrete guardrail structure also brings about rainwater drainage problems. Dust and foreign objects on the bridge deck enter the drainage channels with rainwater, which can easily cause blockages, reduce drainage efficiency, make it difficult to remove residues, increase the difficulty of cleaning for workers, and allow bacteria to grow in the drainage pipes, producing odors.

[0003] Existing bridge drainage anti-clogging devices are mostly simple filter plate structures. However, as foreign objects such as mud and sand accumulate, the filter holes inevitably become clogged, leading to blockage and water accumulation in the drainage channel. Therefore, it is necessary to develop an anti-clogging device for bridge drainage channels to address the shortcomings of existing technologies. Utility Model Content

[0006] The drainage duct liner has a limiting cavity in the middle and drainage duct chambers at both ends. The two ends of the limiting cavity are connected to the opposite ends of the two drainage duct chambers. A limiting filter plate is slidably engaged inside the limiting cavity.

[0024] 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.

[0025] like Figures 1 to 4 As shown, this utility model provides an anti-clogging device for bridge drainage channels, comprising,

[0026] The drainage duct liner 1 has a limiting cavity 2 in the middle and drainage duct liner 1 has drainage ducts 3 at both ends. The two ends of the limiting cavity 2 are respectively connected to the opposite ends of the two drainage ducts 3. A limiting filter plate 4 is slidably engaged inside the limiting cavity 2. A connecting sleeve 7 is fixedly connected to the outer surface of the limiting filter plate 4 near the center of the drainage duct liner 1. The other end of the connecting sleeve 7 passes through the limiting cavity 2 and the drainage duct 3 and extends to the outside of the drainage duct liner 1, and is fixedly connected to a flow guide filter plate 5. The flow guide filter plate 5 and the limiting filter plate are fixedly connected. The interior of the filter plate 4 is evenly distributed with anti-clogging filter holes 6. Due to the setting of the connecting sleeve 7, the limiting filter plate 4 can move with the flow guiding filter plate 5. Under the action of the buoyancy of the accumulated water, the flow guiding filter plate 5 rises, and the water accumulated at the front end of the drain liner pipe 1 can be filtered through the connecting sleeve 7 and then discharged through the anti-clogging filter holes 6 in the limiting filter plate 4, thus achieving the effect of preventing clogging. After the accumulated water is discharged, the flow guiding filter plate 5 can be slowly reset through the connecting sleeve 7 and the limiting filter plate 4 under the action of water flow, so as to prepare for the next anti-clogging.

[0027] The outer surfaces of the limiting filter plate 4 and the connecting sleeve 7 are both smooth. The connecting sleeve 7 is a flexible filter screen structure. The connecting sleeve 7 is sealed inside the drain cavity 3, and the limiting filter plate 4 is sealed inside the limiting cavity 2. Due to the setting of the connecting sleeve 7, the flow guiding filter plate 5 and the limiting filter plate 4 can be connected to each other, ensuring that the limiting filter plate 4 moves with the flow guiding filter plate 5 under the action of buoyancy. At the same time, it ensures that the flow guiding filter plate 5 moves in the opposite direction with the limiting filter plate 4 under the action of water flow impact, thereby achieving the effect of automatic anti-clogging. At the same time, it ensures that after resetting, it is ready for the next automatic anti-clogging.

[0028] When the side of the limiting filter plate 4 away from the flow guide filter plate 5 is attached to the side of the limiting cavity 2 away from the flow guide filter plate 5, the flow guide filter plate 5 moves with the connecting sleeve 7 and is attached to the outer surface of the drain liner 1 near the flow guide filter plate 5.

[0029] Among them, the flow guide filter plate 5 is a hollow structure and a lightweight floating structure. The side of the outer surface of the flow guide filter plate 5 closest to the inner liner pipe 1 of the drainage channel is attached to the end of the inner liner pipe 1 of the drainage channel, and the side of the outer surface of the flow guide filter plate 5 away from the inner liner pipe 1 of the drainage channel is a smooth arc protrusion structure. Due to the setting of the flow guide filter plate 5, its front end is a smooth protrusion, which can reduce the accumulation of foreign objects, greatly reduce the probability of blockage, and extend its drainage life. Moreover, due to its hollow and lightweight nature, it can float upward with the accumulated water, thereby moving away from the inner liner pipe 1 of the drainage channel and promoting the detachment of foreign objects accumulated at its front end, while achieving the effect of automatic anti-blockage.

[0030] The anti-clogging filter hole 6 has a smooth inner wall and a cross-section of a horizontally placed frustum structure. The inner diameter of the anti-clogging filter hole 6 gradually increases along the direction from the guide filter plate 5 to the limiting filter plate 4. Because the inner cavity of the anti-clogging filter hole 6 is smooth and the inner diameter gradually increases at one end along the drainage direction, it ensures that the impurity particles entering can pass smoothly through the anti-clogging filter hole 6 without getting blocked inside.

[0031] Among them, the inner diameter of the limiting cavity 2 is larger than the inner diameter of the drain cavity 3, the outer diameter of the limiting filter plate 4 is adapted to the inner diameter of the limiting cavity 2, and the outer diameter of the connecting sleeve 7 is adapted to the inner diameter of the drain cavity 3.

[0032] Among them, a positioning guide ring 12 is fixedly sleeved on the outer surface of the drainage channel liner 1 near the flow guide filter plate 5. The cross-section of the positioning guide ring 12 is a right triangle, and the outer surface of the positioning guide ring 12 near the flow guide filter plate 5 is a smooth inclined surface. Due to the setting of the positioning guide ring 12, after the drainage channel liner 1 is installed into the drainage channel as a whole through two wear-resistant sealing airbags 9, the positioning guide ring 12 can be tightly attached to the front end of the drainage channel, ensuring that the water flow is completely discharged through the flow guide filter plate 5, the connecting sleeve 7 and the limiting filter plate 4, achieving a good filtration effect.

[0033] Among them, the outer side of the drainage channel liner pipe 1 is equipped with two wear-resistant sealing airbags 9, and the inside of the wear-resistant sealing airbags 9 is provided with a pressure-resistant air storage chamber 10, which is filled with compressed gas.

[0034] An adjusting ring 8 is provided between the wear-resistant sealing airbag 9 and the drainage channel liner 1, and the adjusting ring 8 is fixedly sleeved inside the wear-resistant sealing airbag 9.

[0035] The inner liner of the drainage channel 1 and the adjusting ring 8 are provided with an adjusting adapter thread 11. The adjusting ring 8 is movably connected to the outer surface of the inner liner of the drainage channel 1 through the adjusting adapter thread 11. Due to the setting of the adjusting ring 8 and the adjusting adapter thread 11, it is ensured that the operator can adjust the position of the two wear-resistant sealing airbags 9 along the outer surface of the inner liner of the drainage channel 1, ensuring that the two wear-resistant sealing airbags 9 can be tightly clamped and fitted inside the drainage channel after adjustment, and at the same time ensuring that the positioning guide ring 12 can be tightly attached to the front end of the drainage channel.

[0036] Working principle and usage process of this utility model:

[0037] Adjust the position of the two wear-resistant sealing airbags 9 outside the inner liner tube 1 according to the length of the inner cavity of the drainage channel. By rotating the adjusting ring 8, the two wear-resistant sealing airbags 9 can be moved to the required position with the help of the adjusting adapter thread 11. Then, with the help of compressed air in the pressure-resistant air storage chamber 10, insert the entire inner liner tube 1 into the drainage pipe, and ensure that the two wear-resistant sealing airbags 9 are tightly clamped between the drainage pipe and the inner liner tube 1. At the same time, ensure that the positioning guide ring 12 is attached to the front end of the drainage pipe to complete the installation.

[0038] In daily use, the anti-clogging filter holes 6 in the flow guide filter plate 5 and the limiting filter plate 4 ensure that the water is filtered and discharged, preventing foreign objects from entering the drainage pipe.

[0039] If the flow guide filter plate 5 becomes clogged, water will accumulate at the air front end. Once the water comes into contact with the flow guide filter plate 5, it will slowly float upward under the buoyancy of the air inside, promoting the removal of foreign objects accumulated on its surface. The water will then drive the limiting filter plate 4 to slide along the inside of the limiting cavity 2 through the connecting sleeve 7. When the flow guide filter plate 5 moves away from the drain liner pipe 1, the water around the front end of the drain liner pipe 1 will enter the connecting sleeve 7 after being filtered by the connecting sleeve 7, and finally be discharged through the anti-clogging filter hole 6 inside the limiting filter plate 4. When the water level is lower than the flow guide filter plate 5, the impact of the water flow on the limiting filter plate 4 will cause it to move in the opposite direction along the inside of the limiting cavity 2. The connecting sleeve 7 will pull the flow guide filter plate 5 to reset it, and finally it will stick to the front end of the drain liner pipe 1 again.
