Example 2

As larger sundries such as soil blocks, stones and the like enter the comb tooth gaps 23 and are gathered in the comb tooth gaps 23, the comb tooth gaps 23 can be blocked due to the long-time and large-amount gathered sundries such as soil blocks, stones and the like; in case broach clearance 23 blocks up, can cause the ponding on the bridge board 1 to be unable to get rid of, also can cause parts such as water conservancy diversion area 3 to lose effect, and in heavy rain weather, more ponding influences the vehicle safety and goes on the bridge. Further improvements to the present device are therefore needed to address the problem of comb gap 23 clogging.

Specifically, as shown in fig. 2, two sides of the comb plate 20 are staggered with each other to form comb teeth 22, and a comb tooth gap 23 is formed between two adjacent comb teeth 22 on one side and the comb teeth 22 on the other side; on one hand, the comb tooth gap 23 is used for discharging rainwater, soil dust, small stones and other impurities onto the lower flow guide belt 3 and then discharging the impurities from the flow guide belt 3; on the other hand, the comb tooth gap 23 is used for matching with the expansion and contraction of the bridge, so that a sufficient gap is reserved for the expansion and contraction of the bridge, and the safety of the bridge is ensured.

Therefore, on one hand, the cleaning heads 29 arranged in a staggered mode on two sides can be ensured to correspond to the comb tooth gaps 23 arranged in a staggered mode on two sides, and in the process that the cleaning heads 29 on two sides move, the cleaning heads can enter and exit the comb tooth gaps 23 simultaneously and clean the comb tooth gaps 23 on two sides; on the other hand, when the cleaning heads 29 are not used, the cleaning heads are driven to the initial positions through related parts, at the moment, the two cleaning heads 29 are respectively extruded on the lower surfaces of the two comb teeth 22 adjacent to each other at two sides, and the comb tooth gaps 23 are prevented from being blocked to influence the normal drainage of the comb tooth gaps 23.

Specifically, the shape of the cleaning head 29 is matched with the shape of the comb tooth gap 23; the size of the cleaning head 29 is smaller than that of the comb tooth gap 23, so that the cleaning head 29 can smoothly enter and exit the comb tooth gap 23 when cleaning the comb tooth gap 23, and the blockage in the comb tooth gap 23 can be cleaned; meanwhile, the shape of the cleaning head 29 is matched with that of the comb tooth gap 23, so that the cleaning area and the cleaning effect of the cleaning head 29 on the comb tooth gap 23 are improved to the maximum extent. As shown in fig. 9, when the cleaning head 29 extends into the comb gap 23 and the elastic portion 28 extends naturally, the height of the cleaning head 28 is equal to that of the comb teeth 22, so that it can be ensured that the elastic portion 28 drives the cleaning head 29 to enter the comb gap 23, and the elastic portion 28 recovers the elastic deformation of the compressed state, pushes the cleaning head 28 to move upwards, so as to extrude the blockage from the comb gap 23, thereby ensuring the cleaning effect on the blockage in the comb gap 23.

Specifically, as shown in fig. 8 and 9, the elastic portion 28 is an elastic telescopic sleeve, and the elastic portion 28 is screwed to the upper end of the cleaning rod 27. In the process that the elastic part 28 drives the cleaning head 29 to move, when the elastic part 28 drives the cleaning head to move to the position right below the comb teeth 22, the elastic part 28 is compressed due to the extrusion of the lower surface of the comb teeth 22 on the cleaning head 29; when the elastic part 28 drives the cleaning head 29 to move into the comb tooth gap 23, due to the effect of the elastic compression recovery of the compressed elastic part 28, the cleaning head 29 moves upwards and extrudes the blockage in the comb tooth gap 23, so that the blockage is loosened and falls off, and after the elastic part 28 drives the cleaning head 29 to leave the comb tooth gap 23, the loosened and fallen blockage falls on the flow guide belt 3 and is further removed by the flow guide belt 3. By controlling the elastic coefficient of the elastic part 28 and according to the degree that the blockage blocks the comb tooth gap 23, the cleaning head 29 can knock the comb tooth 23 to vibrate the comb tooth 23, so that the effect of dropping the blockage from the comb tooth gap 23 is improved, and the cleaning effect of the blockage is further improved; specifically, as shown in fig. 11 (a), (b), and (c), when the blockage is at the height of the blockage part from top to bottom in the comb gap 23, the elastic part 28 drives the cleaning head 29 to move from the current comb gap 23 to the next comb gap 23, and due to the elastic action of the elastic part 28, when the cleaning rod 27 drives the elastic part 28 to move, because the cleaning head 29 is still clamped in the comb gap 23, the movement of the cleaning head 29 lags behind the movement of the elastic part 28, at this time, the elastic part 28 bends and pulls out the cleaning head 29 from the current comb gap 23, and when the cleaning head 29 is pulled out from the current comb gap 23, the cleaning head is pressed on the lower surface of the comb 22, and because the cleaning rod 27 drives the advance movement of the elastic part 28, the elastic part 28 is still in a bent state and continuously drives the cleaning head 29 above the cleaning head to press against the lower surface of the comb 22, when the cleaning head 29 is completely separated from the lower surface of the comb teeth 22, as no obstacle exists above the cleaning head 29, the bent elastic part 28 recovers bending deformation and drives the cleaning head 29 to swing, so that the cleaning head 29 is knocked on the next comb tooth 22, the knocked comb tooth 22 vibrates, and the blockage blocked in the comb tooth gap 23 is loosened, scattered and dropped, thereby improving the cleaning effect of the blockage; simultaneously, when the bending deformation is recovered to elastic part 28, because cleaning head 29 no longer receives the extrusion of broach 22 lower surface, elastic part 28 no longer is compressed and upwards extends, at the in-process that elastic part 28 extends, upwards extrude the jam in broach clearance 23 through cleaning head 29 of its top, make the jam in broach clearance 23 become flexible, scatter, drop, leave this broach clearance 23 at cleaning head 29 after, become flexible, scatter, the jam that drops transfers water conservancy diversion area 3, and then clear away by water conservancy diversion area 3. Thus, under the mutual cooperation of the elastic portion 28 and the cleaning head 29: on one hand, the elastic part 28 generates bending deformation and enables the cleaning head 29 to knock the comb teeth 22 in the process of recovering the bending deformation, so that the comb teeth 22 generate vibration, and the loosening, scattering and falling-off of sundries stuck on the comb teeth 22 and blocking objects in the corresponding comb tooth gaps 23 are promoted; on the other hand, the elastic part 28 is extruded to generate shrinkage deformation due to the extrusion of the lower surface of the comb teeth 22 to the cleaning head 29, after the cleaning head 29 enters the comb tooth gap 23 and the extrusion is released, the extrusion shrinkage deformation of the elastic part 28 is recovered to drive the cleaning head 29 to move upwards, and upward extrusion force is generated on the blockage in the comb tooth gap 23 to promote the blockage to loosen and fall off; the two parts are matched with each other, and the cleaning effect of the high blockage is improved in the process of common movement. The screw rod 8 rotates forwards and backwards repeatedly to drive the cleaning mechanism to move in and out repeatedly through the connecting rod 24 and the cleaning rod 27, so that the elastic part 28 and the cleaning head 29 on the cleaning mechanism clean the comb tooth gaps 23 for multiple times until the required cleaning effect is achieved.

Because the elastic part 28 is in threaded connection with the upper end part of the cleaning rod 27, after the cleaning mechanism is repeatedly used for a long time, the elastic part 28 is deformed and loses efficacy or the cleaning head 29 is damaged, the elastic part 28 can be unscrewed from the cleaning rod 27, and the new elastic part 28 and the new cleaning head 29 are replaced, so that the cleaning effect of the cleaning mechanism on the comb tooth gap 23 is ensured.

In summary, the rotating disc is rotated to drive the screw rod 8 to rotate, so that the moving block 9 moves on the surface of the screw rod 8, on one hand, the moving block 9 drives the three rollers 12 to move below the diversion belt 3, so as to clean up rainwater, soil, stones and other impurities collected on the diversion belt 3, and discharge the rainwater, soil, stones and other impurities collected on the diversion belt 3; on the other hand, the moving block 9 simultaneously drives the connecting rods 24 at the two sides to slide in the sliding grooves 25, the connecting rods 24 drive the cleaning rods 27 to synchronously move in the sliding cavities 26, and the cleaning rods 27 drive the cleaning mechanisms above the cleaning rods 27 to move; the elastic part 28 of the cleaning mechanism drives the cleaning head 29 above the cleaning mechanism to move, so that the cleaning head 29 enters the comb tooth gap 23 and cleans impurities such as soil, stones and the like blocked by the cleaning head. Through the mutual cooperation of above-mentioned parts, can in time clear away the debris on broach clearance 23 and water conservancy diversion area 3 in time, guarantee broach plate 20 normal work, provide the powerful guarantee for passing safely on bridge plate 1.
