Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0034] Example 1
[0035] A filtering and anti-blocking mechanism of a bridge drainage device, comprising: an outer cylinder 1, an inner cylinder 2, a down-pressing pile 4, an elastic linkage rod, and a vibration structure;
[0036] like Figure 1 , an inner cylinder 2 is arranged inside the outer cylinder 1, and the inner cylinder 2 and the outer cylinder 1 are arranged concentrically; a drainage channel 3 is formed between the outer wall of the inner cylinder 2 and the inner wall of the outer cylinder 1; the accumulated water flows through the drainage channel 3 and is discharged; in the drainage channel 3, and between the lower bottom edge of the inner cylinder 2 and the lower bottom edge of the outer cylinder 1, the attached rods 102 are arranged equidistantly in a circle, and the inner and outer cylinders are connected by the attached rods 102; a filter screen 103 is arranged between the upper end edge of the inner cylinder 2 and the upper end edge of the outer cylinder 1, and the filter screen 103 can filter out large impurities before the accumulated water enters the drainage channel 3 to prevent it from entering the drainage channel 3;
[0037] The lower end of the inner cylinder 2 is closed, and a down-pressing pile 4 is movably arranged at the upper end opening. A protrusion is arranged on the outer wall of the down-pressing pile 4, and the protrusion is arranged around the outer wall of the down-pressing pile 4; an elastic linkage rod is arranged below the down-pressing pile 4, and the elastic linkage rod includes: a damping rod 5 and an elastic member 6; the piston telescopic end of the damping rod 5 is arranged on the bottom surface of the down-pressing pile 4, and the lower end of the damping rod 5 is arranged on the bottom surface of the inner cylinder 2; an elastic member 6 is sleeved on the outer periphery of the damping rod 5, and the elastic member 6 here can be a spring; the upper end of the spring is arranged on the bottom surface of the down-pressing pile 4, and the lower end is arranged on the bottom surface of the inner cylinder 2;
[0038] The pressing pile 4 is pressed, and the damping rod 5 moves downward together with the spring; the pressing pile 4 is released, and the damping rod 5 together with the spring drives the pressing pile 4 to return to its original position.
[0039] like Figure 3 , a concave-convex ridge 201 structure is arranged on the inner wall of the inner cylinder 2, and the concave-convex ridge 201 structure is all over the inner wall of the inner cylinder 2; the concave-convex ridge 201 structure is the main vibration structure for generating vibration of the inner cylinder wall; specifically: the vehicle rolls over the down-pressed pile 4, the down-pressed pile 4 moves downward, and at the same time, the protrusion on the outer wall of the down-pressed pile 4 slides over the concave-convex ridge 201, generating vibration for the entire inner cylinder 2, and through the effect of vibration, the mud and sand attached to the outer wall of the inner cylinder 2 falls off;
[0040] The outer wall of the inner cylinder, the inner wall of the outer cylinder, and the down-pressing pile 4 are all made of smooth stainless steel, which reduces the friction of the mud and sand and makes it easy to fall off; the concave-convex ribs 201 and the protrusions are made of rubber, and the protrusions of the rubber material are in direct contact with the concave-convex ribs 201, which will not cause deformation of the two and affect the later use effect; prolong the service life;
[0041] As a preferred embodiment, the raised portion on the above-mentioned push-down pile 4 is arranged at the lower bottom edge of the push-down pile 4. The purpose of being arranged at the lower bottom edge is to make the sliding distance of the raised portion on the concave-convex ridge 201 the longest and generate the longest vibration during the downward movement of the push-down pile 4; if the push-down pile 4 is rolled until the upper surface is flush with the upper end opening of the inner cylinder 2, then the contact sliding distance between the raised portion and the concave-convex ridge 201 is almost equal to the height of the push-down pile 4, and the same is true when the push-down pile 4 is released and reset;
[0042] like Figure 5 In addition to being directly set on the lower bottom edge of the lower pressure pile 4, a pressure plate 401 can also be set on the bottom surface of the lower pressure pile 4, and the pressure plate 401 is also made of rubber as a whole; the outer diameter of the pressure plate 401 is larger than the lower pressure pile 4, and the edge of the pressure plate 401 is set to a circular arc convex structure, then the part of the pressure plate 401 protruding from the lower pressure pile 4 is equivalent to the above-mentioned protrusion; and the circular arc convex part of the edge of the pressure plate 401 can be just located in the concave part of the concave-convex rib 201; the bottom surface of the pressure plate 401 is equivalent to the bottom surface of the lower pressure pile 4.
[0043] As a preferred embodiment, in addition to the protrusions provided at the lower bottom edge of the lower pressure pile 4 or the protrusions formed by the protruding part of the pressure plate, several circles of protrusions can also be provided at equal intervals on the outer wall of the lower pressure pile 4; in this way, multiple circles of protrusions can contact the concave and convex ridges 201 at the same time, which can enhance the vibration effect.
[0044] like Figure 6 The filtering and anti-blocking mechanism of the bridge drainage device in this embodiment is arranged in the drainage holes arranged on the bridge deck; a plurality of holes are arranged side by side on the bridge deck, and a filtering and anti-blocking mechanism is arranged in each hole; a main drainage pipe is arranged under these filtering and anti-blocking mechanisms, and the accumulated water enters from the drainage channels of each filtering and anti-blocking mechanism and finally converges into the main drainage pipe for discharge.
[0045] Example 2
[0046] Based on the embodiment 1, the filtering anti-blocking mechanism provided in the embodiment 1 has the inner cylinder 2 as the main area where vibration is generated, and the outer wall of the inner cylinder 2 has the best effect of sediment vibration shedding; and although the outer cylinder 1 can also have a vibration effect through the conduction of the attachment rod 102 and the filter screen 103, the vibration effect is inferior to that of the inner cylinder 2;
[0047] Therefore, a roller brush mounting rod is provided on the cylinder wall in the drainage channel 3, and a roller brush 8 is movably provided on the roller brush mounting rod; the installation position of the roller brush 8 needs to enable the bristles to contact the outer wall of the inner cylinder 2 and the inner wall of the outer cylinder 1 at the same time;
[0048] The above-mentioned roller brush mounting rod can be a straight rod. In order to meet the installation position requirements of the roller brush 8, it is necessary to select two points on the inner wall of the outer cylinder 1 as fulcrums for installing a roller brush mounting rod; such straight mounting rods need to be staggered in the vertical direction of the outer cylinder 1 to avoid mutual interference, and in order to meet the installation position requirements of the roller brush, there are very few roller brush positions on such a straight rod that meet the installation position requirements.
[0049] Therefore, in order to arrange as many roller brushes 8 as possible in the same horizontal plane in the vertical direction of the outer cylinder 1 so that it can cover the cylinder wall, and no matter where the roller brush is arranged on the roller brush mounting rod, the bristles can contact the outer wall of the inner cylinder 2 and the inner wall of the outer cylinder 1 at the same time; Figure 1 and Figure 4 The roller brush mounting rod is set as a circular ring rod 7, the ring rod 7 is set on the outer periphery of the inner cylinder 2, and a support rod 701 is set between the ring rod 7 and the outer wall of the inner cylinder 2, and the ring rod 7 is fixed by the support rod 701; the roller brush 8 is rotatably mounted on the ring rod 701, and rainwater enters from the drainage channel 3 and washes onto the roller brush 8, and the roller brush 8 can rotate on the ring rod 701. During the rotation process, the bristles brush and clean the inner and outer cylinder walls to remove the attached mud and sand. Multiple sets of ring rods 7 and roller brushes 8 can be installed as needed.
[0050] The above-mentioned roller brush 8 is installed on the ring rod 7 at fixed points and equal intervals. Its position relative to the ring rod 7 is fixed, and it can rotate at a fixed point to brush the inner and outer cylinder walls; however, such a roller brush installation position may not be able to clean the position that the roller brush 8 cannot cover;
[0051] As a more preferred embodiment, the above-mentioned roller brush 8 is not set at a fixed point on the circle rod 7, and the roller brush 8 can slide freely relative to the circle rod 7; in this way, when the roller brush 8 is flushed by the water flow, the roller brush 8 rotates on the circle rod 7 to brush the inner and outer cylinder walls. On the other hand, the roller brush 8 can slide freely on the circle rod 7, so that a circle of the inner and outer cylinder walls can be fully covered.
[0052] Example 3
[0053] Based on the first or second embodiment, when the pressure pile 4 is in the original position, its height above the road surface does not form an obstacle for the motor vehicles traveling on the bridge deck; however, there can still be a smooth transition between the pressure pile 4 and the wheel; Figure 2 or Figure 3 A curved rubber pad 402 made of rubber is arranged on the upper end surface of the down-pressing pile 4; the curved rubber pad 402 plays a role of smooth transition when the vehicle rolls over the down-pressing pile 4.
[0054] The upper surface of the arc-shaped rubber pad 402 is covered with a reflective film, which can serve as a reminder on some complex roads during driving.
[0055] Example 4
[0056] Based on any one of Embodiments 1 to 3, Figure 1 , attachment ears 101 are symmetrically arranged on the outer wall of the upper end of the outer cylinder 1, and screw holes are arranged on the attachment ears 101; the device can be fixed on the bridge deck as a whole by using screws or expansion screws.
