Description

A highway drainage filtering and anti-blocking device

Technical Field

The invention relates to the technical field of highway drainage facilities, and in particular to a highway drainage filtering and anti-blocking device.

Background technique

In order to ensure driving safety and road safety, highway projects need to set up drainage systems on the edge of the highway to drain the accumulated water into sewage pools or rivers, lakes, seas and other water bodies through drainage ditches. In order to improve drainage efficiency and drainage quality, existing drainage systems will add filtering devices to the drainage system. The filtered sewage can not only avoid pipe blockage, but also reduce the difficulty of subsequent sewage treatment. However, when the current filtering devices are in use, it is easy for too much debris to accumulate in the filtering devices, resulting in poor drainage of the drainage system, or even blockage, affecting the normal discharge of rainwater, and the slag removal of the filtering devices is very troublesome, and each device needs to be opened for manual cleaning.

Summary of the invention

In view of the deficiencies in the prior art, the present invention proposes a highway drainage filtering and anti-blocking device, which can prevent the drainage pipe from being blocked.

In order to achieve the above-mentioned purpose, the present invention is implemented through the following technical scheme: a highway drainage filtering and anti-blocking device, comprising a drainage pipe one, a drainage pipe two, a filter part and a collecting part; the drainage pipe one is arranged in the vertical direction, and the top is connected to the drainage ditch, the filter part is arranged in the drainage pipe one, including a filter net, the edge of the filter net is circumferentially provided with a mounting frame, the inner wall of the drainage pipe one is provided with a spring sheet, the outer wall of the mounting frame is provided with a pressing sheet, and the pressing sheet is mounted on the spring sheet; the collecting part includes a collecting trough, the collecting trough is arranged at the bottom of the drainage pipe one, the drainage pipe two is connected to the drainage pipe one, and the connection is located between the collecting trough and the filtering part.

After the accumulated water in the drainage ditch enters the drainage pipe one, the debris can be intercepted and filtered through the internal filter net, and the filtered sewage is discharged into the drainage pipe two. When the internal debris accumulates to a certain weight, the spring sheet cannot support the mounting frame and rotates downward, and the mounting frame and the filter net fall into the collection tank.

The beneficial effect of the above-mentioned highway drainage filtering and anti-blocking device is that during the drainage process, the filter part can filter and intercept the debris in the sewage, and automatically fall into the collection part after collecting a certain amount, thereby achieving the effect of filtering the accumulated water and maintaining smooth drainage to avoid blockage.

Furthermore, the filter unit further comprises a driving gear, a driven gear, a sector-shaped tooth and a storage tube, wherein the driving gear, the driven gear and the sector-shaped tooth are all rotatably arranged on the outside of the first drain pipe, one side of the driving gear penetrates into the inner wall of the first drain pipe, the driven gear meshes with the driving gear, and the two sector-shaped teeth are respectively arranged on both sides of the driven gear, and both are provided with a transmission gear meshing with the driven gear;

The storage tube is arranged along the axial direction of drain pipe one, and one side of the bottom is connected to drain pipe one, and a push rod is inserted on the other side. The end of the push rod away from drain pipe one is connected to a double-sided rack, and the two fan-shaped teeth can alternately engage with the double-sided rack. A plurality of filter screens are axially arranged in the storage tube, and the outer wall of the mounting frame of the filter screen is provided with an active rack that can engage with the active gear.

When the filter screen and the mounting frame move axially along the drain pipe 1, the active rack on the outer wall of the mounting frame drives the active gear to rotate, and drives the driven gear to rotate, and the driven gear drives the two sector teeth on both sides to rotate, and the two sector teeth alternately mesh with the double-sided racks, driving the double-sided racks to move axially, first pushing the filter screen at the bottom of the storage tube into the drain pipe 1, and then moving back in the axial direction, and the multiple filter screens in the storage tube fall down, which is convenient for pushing out next time.

Furthermore, a groove is provided on the outer wall of the mounting frame, and the push rod can be plugged into the groove. Two rotatably connected limit rods are symmetrically provided on the inner wall of the drain pipe. Both sides of the mounting frame are provided with protrusions, and the protrusions can push the limit rod to rotate. The limit rod has a limit point when rotating toward the storage tube.

After the push rod is plugged into the mounting frame, the mounting frame and the filter screen can be pushed into the drain pipe. During the pushing process, the protrusion pushes the limit rod upward. When the push rod is retracted, the protrusion contacts the limit rod again. After the limit rod reaches the limit point, the mounting frame cannot move, thereby causing the push rod and the mounting frame to separate.

Furthermore, the inner wall of the drain pipe 1 is provided with symmetrically arranged limit blocks along the axial direction, the limit blocks are T-shaped blocks, and the outer wall of the mounting frame is provided with limit grooves slidably connected to the limit blocks.

When the filter screen slides down, the limit block and the limit groove can limit the movement trajectory of the filter screen and the mounting frame, ensuring the axial movement along the drain pipe, avoiding overturning and causing jamming in the pipe.

Furthermore, a counterweight block is provided in the storage tube, and the counterweight block is located above the topmost filter mesh.

The weight of the filter screen in the storage tube can be increased by the counterweight block, thereby ensuring the plug-in fit between the push rod and the groove of the mounting frame.

Furthermore, the collecting part also includes a drain plate, which is arranged above the collecting trough and located at the connection between drain pipe one and drain pipe two, and one end of the drain plate is rotatably connected to the inner wall of drain pipe one through a spring hinge.

During drainage, the sewage is filtered through drain pipe one and enters drain pipe two through the drainage plate. When the filter falls, the accumulated debris has a certain weight and falls on the drainage plate, which can drive the drainage plate to rotate and fall into the collection tank below.

Furthermore, a drainage pipe three connected to the drainage pipe two is provided at the bottom of the collecting tank.

The sewage entering the collection tank can be discharged through the drainage pipe three to prevent the drainage plate from floating up due to excessive water accumulation and causing blockage in the pipe.

Furthermore, a slot is circumferentially provided on the inner wall of the mounting frame, the filter is inserted into the slot, a plurality of slide grooves are provided at the bottom of the slot, a plurality of slide columns are provided on the edge of the filter, the slide columns correspond to the slide grooves one by one and are slidably connected, and the diameter of the slide groove gradually decreases toward the filter.

The edge of the filter is inserted in the mounting frame, so that when the filter is piled with debris, as the weight increases, the middle of the filter gradually falls down, and at the same time drives the slide column to slide in the slide groove, thereby increasing the accommodation space in the filter.

Detailed ways

The following embodiments of the technical solution of the present invention are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

Please refer to Figures 1 to 4. The present invention provides a highway drainage filtering and anti-blocking device, including a drainage pipe 11, a drainage pipe 2, a filter part 20 and a collection part 30. The highway water is discharged through the drainage pipe 11 and the drainage pipe 2 12. During the drainage process, the filter part 20 can filter the debris in the sewage and automatically collect the debris into the collection part 30 after it accumulates to a certain amount, thereby achieving the filtering effect and maintaining smooth drainage.

Specifically, as shown in FIG. 1 and FIG. 2 , the drain pipe 11 is arranged in the vertical direction, the top is connected to the drainage system such as the drainage ditch on the road surface, and the bottom is connected to the drain pipe 2 12. The filter unit 20 includes a filter screen 21 and a mounting frame 22. The edge of the filter screen 21 is arranged on the inner wall of the mounting frame 22 around the circumference. The outer wall of the mounting frame 22 is symmetrically provided with a pressing sheet. The inner wall of the drain pipe 11 is symmetrically provided with a spring sheet 111. Two pressing sheets can be respectively mounted on two spring sheets 111. After the accumulated water on the road enters the drain pipe 11 through the drainage system, the filter screen 21 can intercept and filter the debris in the sewage. When the debris on the filter screen 21 accumulates to a certain weight, the spring sheet 111 cannot bear the weight of the mounting frame 22 and rotates downward, so that the mounting frame 22 and the filter screen 21 can move downward along the axial direction of the drain pipe 11.

The collecting part 30 includes a collecting trough 31 and a drainage plate 32. The collecting trough 31 is arranged at the bottom of the drainage pipe 1 11, and the drainage plate 32 is arranged above the collecting trough 31 and is rotatably connected to the connection between the drainage pipe 1 11 and the drainage pipe 2 12 through a spring hinge. Under normal conditions, the drainage plate 32 can drain the sewage falling from the drainage pipe 1 11 into the drainage pipe 2 12. When the filter screen 21 filled with debris falls onto the drainage plate 32, it drives the drainage plate 32 to rotate downward, so that it can enter the collecting trough 31, and then the drainage plate 32 is reset under the action of elastic force. In this embodiment, a drainage pipe 3 13 connected to the drainage pipe 2 12 is provided at the bottom of the collecting trough 31, so as to facilitate the discharge of sewage in the collecting trough 31 and avoid clogging caused by stagnant water and the drainage plate 32 floating up.

Specifically, the filter unit 20 further includes a driving gear 23, a driven gear 24, a sector gear 25 and a storage tube 26. The driving gear 23, the driven gear 24 and the sector gear 25 are all rotatably arranged on the outside of the drain pipe 11. One side of the driving gear 23 extends into the inner wall of the drain pipe 11. The outer wall of the mounting frame 22 is provided with a driving rack that can mesh with the driving gear 23. When the mounting frame 22 falls, the driving rack can drive the driving gear 23 to rotate. The driven gear 24 meshes with the driving gear 23. In this embodiment, the driving gear 23 and the driven gear 24 mesh through gear transmission. Both sides of the driven gear 24 are provided with sector gears 25, and the sector gears 25 are connected to transmission gears 251 that mesh with the driven gear 24. The storage tube 26 is arranged along the axial direction of the drain pipe 11, and one side of the bottom is connected to the drain pipe 11. A plurality of filter screens 21 are axially arranged inside the storage tube 26. A push rod 27 is inserted on the other side of the bottom of the storage tube 26. A double-sided rack 271 is provided on the push rod 27 and is located between the two sector teeth 25. The two sector teeth 25 can alternately engage with the double-sided rack 271.

When the filter screen 21 is filled with debris and starts to fall, the active gear 23 is driven to rotate by the active rack, thereby driving the driven gear 24 and the fan-shaped gear 25 to rotate together, and the fan-shaped gear 25 can alternately drive the double-sided rack 271 to move axially, so that the push rod 27 first pushes the filter screen 21 at the bottom of the storage tube 26 into the drain pipe 11, and then retreats to allow the remaining filter screens 21 to fall, so that a new filter screen 21 can be put into the pipe after each filter screen 21 is filled with debris. In this embodiment, the inner wall of the drain pipe 11 is provided with a symmetrically arranged limit block 113 along the axial direction, and the limit block 113 is a T-shaped block. The outer wall of the mounting frame 22 is provided with a limit groove that is slidably connected to the limit block 113. When the filter screen 21 and the mounting frame 22 are pushed into the drain pipe 11, the position of the limit groove and the limit block 113 corresponds, and they can be slidably connected when falling, so as to limit the moving track of the filter screen 21 and avoid tipping in the pipe to cause blockage.

Furthermore, a groove is provided on the outer wall of the mounting frame 22, and the end of the push rod 27 can be plugged into the groove. Two rotationally connected limit rods 112 are symmetrically provided on the inner wall of the drain pipe 11, and protrusions 221 are provided on both ends of the mounting frame 22. The limit rod 112 has a limit point when rotating toward the receiving tube 26, and is in a vertical state when located at the limit point. After the push rod 27 is plugged into the mounting frame 22, it is pushed into the drain pipe 11. During the pushing process, the protrusion 221 rotates the limit rod 112 to the right and lifts it upward, so that it can enter smoothly. When the push rod 27 is retracted, it drives the mounting frame 22 to move together. At this time, the limit rod 112 rotates to a vertical state under the action of gravity, and the protrusion 221 cannot push the limit rod 112, so that the push rod 27 is separated from the mounting frame 22, and the mounting frame 22 can be placed on the spring sheet 111.

In this embodiment, there is a large friction between the push rod 27 and the groove, which can drive the mounting frame 22 to move. Therefore, a counterweight block 261 is provided in the storage tube 26, located on the top mounting frame 22, to increase the downward pressure and ensure that the push rod 27 can be inserted into the groove.

Specifically, as shown in Fig. 3 and Fig. 4, the inner wall of the mounting frame 22 is provided with a slot 222 around the circumference, and the edges of the filter 21 are inserted into the slot 222. A plurality of slide grooves 223 are provided around the circumference of the slot 222, and a plurality of slide posts 211 are provided at the edge of the filter 21. The slide posts 211 correspond to the slide grooves 223 one by one and are slidably connected, and the slide grooves 223 gradually decrease in diameter toward the filter 21. After the debris falls on the filter 21, as the weight increases, the middle part of the filter 21 can be gradually dropped, and the edge can be gradually pulled out of the slot 222, and the slide post 211 can be driven to slide in the slide groove 223. The slide groove 223 gradually decreases in diameter, so that the friction force on the slide post 211 increases, and the filter 21 can be driven to slowly drop as the weight increases, thereby increasing the accommodation space of the filter 21.

The working principle of the above-mentioned highway drainage filtering and blocking prevention device is as follows: the accumulated water on the highway road surface is discharged into the drainage pipe 11 through the drainage system, and the filter net 21 can intercept and filter the debris and impurities in the drainage. When the debris is large and heavy, the spring sheet 111 cannot carry the mounting frame 22, and the mounting frame 22 and the filter net 21 slide down, driving the driving gear 23 to rotate during the sliding process, and through the transmission of the driven gear 24 and the fan-shaped gear 25, the push rod 27 can be driven to plug and match with the mounting frame 22 in the receiving tube 26, and pushed into the drainage pipe 11, and then retracted. During the retraction process, with the cooperation of the protrusion 221 and the limit rod 112, the new mounting frame 22 and the filter net 21 are set in the drainage pipe 11. The mounting frame 22 and the filter net 21 filled with debris drive the drainage plate 32 to rotate and fall into the collection tank 31 for subsequent unified processing.

The above-mentioned highway drainage filtering and anti-blocking device can not only filter the accumulated water discharged from the highway and intercept sundries and impurities, but also automatically replace the filter net in time to keep the drainage pipe unobstructed and avoid blockage.

The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents.
