[0028] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments. Example 1

[0029] like Figures 1 to 3As shown in the embodiment of the present invention, a novel environmentally friendly drainage device for highway engineering includes a highway body 1; water-blocking plates 11 are fixedly connected to both sides of the highway body 1; a filter plate 12 is fixedly connected between the water-blocking plate 11 and the side wall of the highway body 1; multiple sets of support columns 13 are provided at the top of the filter plate 12; filter holes 14 are opened between a pair of support columns 13 at the top of the filter plate 12; during operation, the multiple sets of support columns 13 installed on the top of the filter plate 12 can create a certain gap when debris blocks the filter holes 14, facilitating the smooth passage of water. At the same time, the gap between the bottom of the filter plate 12 and the water-blocking plate 11 can facilitate the discharge of water. The protrusion of the support columns 13 can reduce the blockage of the filter holes 14 by impurities in the water flow, preventing water accumulation and posing a safety hazard to passing vehicles. In addition, the distance between the bottom of the filter plate 12 and the water-blocking plate 11 can facilitate water infiltration, further reducing water accumulation.

[0030] like Figure 3 As shown, the filter plate 12 has multiple sets of first-level sliding grooves 2 at its top; the support column 13 is slidably connected inside the first-level sliding groove 2; the first-level sliding groove 2 and the support column 13 are connected by a first-level spring 21; a filter screen 22 is provided in the middle of the filter hole 14; the two ends of the filter screen 22 are respectively fixed to the side wall of the support column 13; a first-level roller 23 is fixed to the side wall of the filter plate 12; the filter screen 22 slides on the side wall of the first-level roller 23; during operation, when the support column 13 is impacted by debris, it will move inside the first-level sliding groove 2. At the same time, the downward movement of the support column 13 will cause the filter screen 22 to be flattened inside the filter hole 14, causing the impurities accumulated on the filter screen 22 to bounce upward. The elasticity of the first-level spring 21 can assist the support column 13 in moving, producing an up-and-down movement effect, loosening the blocked debris, leaving gaps to facilitate water flow, further reducing water flow blockage, and increasing vehicle driving safety.

[0031] like Figure 3 As shown, multiple sets of support plates 3 are fixed to the side wall of the filter hole 14; a first magnet 31 is fixed to the top of the support plate 3; a second magnet 32 ​​is fixed to the middle of the filter screen 22; the second magnet 32 ​​and the first magnet 31 are attracted by magnetic force; during operation, the first magnet 31 is supported by the multiple sets of support plates 3, and the second magnet 32 ​​installed on the middle of the filter screen 22 can be attracted by magnetic force with the first magnet 31, so that the filter screen 22 is in a bent state, which makes it convenient for the support column 13 to move and flatten the filter screen 22. By using the magnetic attraction between the second magnet 32 ​​and the first magnet 31, the support column 13 can generate a certain vibration effect after flattening the filter screen 22, which loosens the impurity particles attached to the filter screen 22, reduces accumulation, and facilitates subsequent cleaning by cleaning personnel.

[0032] like Figure 3As shown, multiple sets of second slides 4 are symmetrically opened on the side wall of the first slide 2; each set of second slides 4 is slidably connected to an impact plate 41; the second slides 4 and the impact plates 41 are connected by a second spring 42; during operation, when the support column 13 is impacted and moved by debris, it will squeeze the impact plate 41 to move inside the second slide 4, causing the support column 13 to have a jerking sensation during its downward movement. Subsequently, it is reset by the second spring 42. The jerking sensation caused by the impact plate 41 obstructing the support column 13 can vibrate the debris accumulated above, guide the water flow through the gap, and reduce the spread of water blockage to the road, thus affecting the normal passage of vehicles.

[0033] like Figures 2 to 4 As shown, a diversion plate 5 is provided at the bottom of the filter plate 12 between the water blocking plate 11 and the side wall of the road body 1; the top of the diversion plate 5 is a sloping surface that is concave towards the middle; a water leakage hole 51 is provided in the middle of the diversion plate 5; a fifth sliding groove 53 is provided on the side wall of the water leakage hole 51; a fan 52 is rotatably connected to the side wall of the fifth sliding groove 53; during operation, the diversion plate 5 installed below the bottom of the filter plate 12 can guide the liquid filtered by the filter hole 14 through the water leakage hole 51, so that it can be discharged through the water blocking plate 11. When the fan 52 is impacted by the water flow and rotates inside the fifth sliding groove 53, it will generate a certain vibration effect. The vibration generated by the fan 52 being impacted by the water flow will loosen the sand and gravel particles remaining on the diversion plate 5, reducing the possibility of blockage.

[0034] like Figure 5 As shown, both the road body 1 and the water-blocking plate 11 have three grooves 6 on their side walls; the two ends of the diversion plate 5 slide inside a pair of three grooves 6 respectively; three magnets 62 are fixed to both sides of the pair of diversion plates 5; the three magnets 62 and the three grooves 6 are connected by a connecting rope 61; a fourth magnet 63 is fixed to the bottom of the three grooves 6; the three magnets 62 and the fourth magnet 63 repel each other magnetically; during operation, after the diversion plate 5 is impacted by the water flow, it is suspended in a suspended state by the connection of the connecting rope 61. At the same time, the magnetic repulsion between the three magnets 62 and the fourth magnet 63 can generate vibration in conjunction with the impact of the water flow. The pulling of the diversion plate 5 by the connecting rope 61, combined with the magnetic repulsion between the three magnets 62 and the fourth magnet 63, can increase the vibration effect and loosen the sand and gravel remaining on the top of the diversion plate 5 through the filter hole 14, reducing the accumulation of sand and gravel on the diversion plate 5.

[0035] like Figure 4As shown, the side wall of the fifth chute 53 has a rotating shaft 7; the rotating shaft 7 and the side wall of the fifth chute 53 are connected by a torsion spring; a connecting rod 71 is fixedly connected to the side wall of the rotating shaft 7; a pair of second rollers 72 are rotatably connected to the end of the connecting rod 71 away from the rotating shaft 7; during operation, when the fan 52 is impacted by the water flow and rotates, it will impact the connecting rod 71, causing the connecting rod 71 to impact the side wall of the fifth chute 53 under the rotation of the rotating shaft 7, generating a vibration effect. At the same time, the rotatability of the second rollers 72 can reduce the jamming between the connecting rod 71 and the fan 52. By using the rotation of the rotating shaft 7, the connecting rod 71 can drive the second rollers 72 to impact the side wall of the fifth chute 53. The vibration effect loosens the sand and gravel particles attached to the diversion plate 5, causing them to fall to the bottom, reducing the accumulation on the diversion plate 5 and ultimately affecting the water leakage effect of the filter hole 14.

[0036] like Figure 4 As shown, a fourth groove 8 is provided on the side wall of the fifth chute 53 at the impact position of the second roller 72; a vibrating plate 81 is slidably connected inside the fourth groove 8; the fourth groove 8 and the vibrating plate 81 are connected by a third spring 82; during operation, as the connecting rod 71 rotates, the second roller 72 impacts the vibrating plate 81, causing the vibrating plate 81 to impact inside the third spring 82, and then move elastically through the third spring 82, producing a multiple impact effect. Utilizing the elasticity of the third spring 82, it can cooperate with the vibrating plate 81 to make multiple impacts inside the fourth groove 8, producing a multiple impact effect, further strengthening the loosening of the gravel attached to the diversion plate 5 and reducing accumulation.

[0037] like Figure 6 As shown, the filter screen 22 has multiple sets of six sliding grooves 9 inside; impact balls 91 are rolled inside the six sliding grooves 9; during operation, when the filter screen 22 is pulled by the support column 13, the impact balls 91 will move inside the six sliding grooves 9, generating multiple impacts according to the pulling amplitude. The impact effect generated by the impact balls 91 further loosens the sand and gravel particles accumulated on the filter screen 22, and at the same time causes the water droplets attached to the filter screen 22 to fall off, reducing the residue of water droplets. Example 2

[0038] like Figure 6 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: multiple sets of rubber plates 101 are fixedly connected inside the sixth slide groove 9; the rubber plates 101 are staggered; during operation, as the impact ball 91 moves, the staggered rubber plates 101 can cause the impact ball 91 to bounce multiple times, increasing the number of impacts. Utilizing the elasticity of the rubber plates 101 themselves, the impact effect of the impact ball 91 can be increased, further reducing the residue of water droplets on the filter screen 22 and reducing the erosion of the filter screen 22 by water droplets remaining for a long time.

[0039] During operation, the multiple sets of support columns 13 installed on the top of the filter plate 12 can create a certain gap when debris is blocked above the filter holes 14, facilitating the smooth flow of water. Simultaneously, the gap between the bottom of the filter plate 12 and the water-blocking plate 11 allows for easy water discharge. When the support columns 13 are impacted by debris, they will move within the first sliding groove 2. This downward movement of the support columns 13 will flatten the filter screen 22 within the filter holes 14, causing the accumulated impurities on the filter screen 22 to bounce upwards. Iron 31 is supported by multiple sets of support plates 3. The second magnet 32 ​​installed in the middle of the filter screen 22 can be magnetically attracted to the first magnet 31, causing the filter screen 22 to be in a bent state. This facilitates the movement of the support column 13, which can then flatten the filter screen 22. When the support column 13 is impacted by debris, it will compress the impact plate 41, causing it to move inside the second slide groove 4. This creates a jerky feeling as the support column 13 moves downwards. Subsequently, it is reset by the second spring 42. The guide plate 5 installed below the bottom of the filter plate 12 can guide the filter holes... The filtered liquid is guided through the drain hole 51 for easy discharge through the water baffle 11. When the fan 52 rotates inside the fifth slide 53 under the impact of water flow, it will generate a certain vibration effect. After the guide plate 5 is impacted by water flow, it is suspended under the connection of the connecting rope 61. At the same time, the magnetic repulsion between the third magnet 62 and the fourth magnet 63 can cooperate with the water flow impact to generate vibration. When the fan 52 rotates under the impact of water flow, it will hit the connecting rod 71, causing the connecting rod 71 to rotate on the first shaft 7. The rotating roller 72 impacts the side wall of the fifth slide 53, generating a vibration effect. At the same time, the rotatability of the second roller 72 can reduce the jamming between the connecting rod 71 and the fan 52. During the rotation of the connecting rod 71, the second roller 72 will impact the vibrating plate 81, causing the vibrating plate 81 to impact inside the third spring 82. Through the elastic movement of the third spring 82, multiple impact effects are generated. When the filter screen 22 is pulled by the support column 13, the impact ball 91 will move inside the sixth slide 9, generating multiple sets of impacts according to the pulling amplitude.
