Description

Technical Field

[0001] This utility model belongs to the field of highway drainage technology, and in particular relates to a highway drainage ditch filter assembly. Background Technology

[0002] During rainy weather, water accumulates on highways. If it cannot be drained in time, it will affect the normal driving of vehicles, reduce road surface friction, increase vehicle braking distance, and even lead to dangerous situations such as vehicle skidding and loss of control. Drainage channels can quickly collect and guide rainwater from the road surface to drain away smoothly, ensuring that the road surface is in a relatively dry and safe driving condition.

[0003] During the process of collecting and discharging rainwater, a large amount of mud, leaves, plastic waste and other debris will flow along with the water in the road drainage ditch. The filter screen can effectively block these debris from entering the drainage outlet and prevent them from further clogging the drainage pipes, culverts and other downstream drainage facilities. In order to facilitate the cleaning of the filter screen, we have designed a road drainage ditch filter screen assembly, which adopts a combination of troughs and elastic structure to make the filter screen quick to replace. Utility Model Content

[0004] The purpose of this invention is to provide a highway drainage ditch filter assembly, which has the advantage of using a combined ditch with an elastic structure, allowing for quick replacement of the filter, thereby solving the aforementioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A highway drainage ditch filter screen assembly includes a fixed pipe welded to the inner cavity of a drainage pipe below the drainage ditch. An installation ring is installed in the inner cavity of the fixed pipe. A cylindrical filter screen extending into the inner cavity of the drainage ditch is fixedly connected to the top of the installation ring. Two symmetrical locking pins are fixedly connected to the surface of the installation ring. Two slots for the locking pins to be inserted are opened at the top of the fixed pipe. A horizontal groove is opened at the bottom of the inner cavity of the slot. A locking groove is opened at the top of the inner cavity of the horizontal groove.

[0006] Preferably, the drain pipe has an annular groove inside, and a movable ring that abuts against the bottom of the locking pin is slidably connected to the inner cavity of the annular groove.

[0007] Preferably, the inner cavity of the annular groove is provided with a spring, and the top of the spring is fixedly connected to the movable ring.

[0008] Preferably, the top of the drainage channel is provided with a placement cavity, and a rain grate is installed in the inner cavity of the placement cavity.

[0009] Preferably, the surface of the cylindrical filter screen is fixedly connected with multiple reinforcing frames, and the bottom of the reinforcing frames is fixedly connected to the mounting ring.

[0010] The beneficial effects of this utility model are:

[0011] 1. This utility model presses the cylindrical filter screen downwards, causing the mounting ring and locking pin to move downwards. The locking pin then drives the movable ring to move downwards and compresses the spring, causing the cylindrical filter screen to rotate. This allows the locking pin to enter the inner cavity of the slot, enabling the cylindrical filter screen and mounting ring to be removed from the fixed tube for replacement. This achieves the purpose of quick filter screen replacement by using a combination slot with an elastic structure.

[0012] 2. This utility model uses the placement cavity and the rain grate together. The rain grate is placed in the inner cavity of the placement cavity, which makes it easy to replace and maintain the rain grate after it is damaged. Attached Figure Description

[0020] In the following description, embodiments of the highway drainage ditch filter assembly of the present invention will be described with reference to the accompanying drawings.

[0021] Figure 1-4This invention illustrates a highway drainage ditch filter assembly according to an embodiment of the present invention. It includes a fixing pipe 3 welded to the inner cavity of a drainage pipe 2 below the drainage ditch 1. A placement cavity 13 is provided at the top of the drainage ditch 1, and a rain grate 14 is installed inside the placement cavity 13. Through the cooperation of the placement cavity 13 and the rain grate 14, the rain grate 14 is placed inside the placement cavity 13, facilitating replacement and maintenance of the rain grate 14 after damage. An installation ring 4 is installed inside the fixing pipe 3, and a cylindrical filter 5 extending into the inner cavity of the drainage ditch 1 is fixedly connected to the top of the installation ring 4. The surface of the mesh 5 is fixedly connected with multiple reinforcing frames. The bottom of the reinforcing frames is fixedly connected to the mounting ring 4. The surface of the mounting ring 4 is fixedly connected with two symmetrical locking pins 6. The top of the fixing tube 3 has two slots 7 for the locking pins 6 to be inserted. The bottom of the inner cavity of the slot 7 is provided with a horizontal groove 8. The top of the inner cavity of the horizontal groove 8 is provided with a locking groove 9. The inside of the drain pipe 2 is provided with an annular groove 10. The inner cavity of the annular groove 10 is slidably connected with a movable ring 12 that abuts against the bottom of the locking pin 6. The inner cavity of the annular groove 10 is provided with a spring 11. The top of the spring 11 is fixedly connected to the movable ring 12.

[0022] Working principle: When using this utility model, pressing down on the cylindrical filter screen 5 causes the mounting ring 4 to move the locking pin 6 downwards, disengaging the locking pin 6 from the inner cavity of the locking groove 9 and entering the inner cavity of the horizontal groove 8. The locking pin 6 presses against the movable ring 12, causing the movable ring 12 to move downwards and putting the spring 11 in a compressed state. Then, rotating the cylindrical filter screen 5 causes it to rotate from the inner cavity of the horizontal groove 8 to the inner cavity of the slot 7. Then, pulling the cylindrical filter screen 5 upwards allows the cylindrical filter screen 5 and the mounting ring 4 to be removed and disassembled from the inner cavity of the fixing tube 3. During installation, the above steps are reversed. When the locking pin 6 is aligned with the locking groove 9, the restoring force of the spring 11 causes the movable ring 12 to drive the locking pin 6 into the inner cavity of the locking groove 9, thus achieving replacement.

[0023] In summary, this highway drainage ditch filter assembly, by pressing down on the cylindrical filter 5, causes the mounting ring 4 and locking pin 6 to move downwards. The locking pin 6 then drives the movable ring 12 to move downwards and compress the spring 11, causing the cylindrical filter 5 to rotate. This allows the locking pin 6 to enter the inner cavity of the slot 7, enabling the cylindrical filter 5 and mounting ring 4 to be removed from the fixed pipe 3 for replacement. This achieves the purpose of using a combined slot and elastic structure to quickly replace the filter.
