Description

Technical Field

[0001] This utility model belongs to the field of bridge drainage technology, specifically a bridge drainage outlet dredging and anti-clogging device. Background Technology

[0002] The bridge deck is blocked by guardrails on both sides. Currently, the guardrails are made of cast concrete, which increases the overall impact resistance and can effectively protect vehicles from breaking through the guardrails in the event of a collision. However, this type of cast concrete guardrail structure also brings about rainwater drainage problems. Dust and foreign objects on the bridge deck enter the drainage channels with rainwater, which can easily cause blockages, reduce drainage efficiency, make it difficult to remove residues, increase the difficulty of cleaning for workers, and allow bacteria to grow in the drainage pipes, producing odors.

[0003] Currently, most bridge drainage holes are still cleared manually. However, the current clearing tools are often just a simple long pole with an inverted cone structure on its surface. This can effectively clear the silt by pushing it in one direction, but its diameter is fixed, making it difficult to clean silt holes of different diameters. Moreover, because the diameter is fixed, it is difficult to insert into the silt when there is high resistance, which greatly reduces the clearing effect. Furthermore, because the inverted cone is fixed, the resistance is high when pulling in the opposite direction, which is extremely physically demanding. Therefore, it is necessary to develop a bridge drainage hole clearing and anti-clogging device to solve the shortcomings of the existing technology. Utility Model Content

[0006] The dredging rod has several evenly distributed adapter slots on its side, with the lower end of each adapter slot extending to the bottom of the dredging rod. Several evenly distributed dredging claws are movably installed inside each adapter slot. A positioning component is fixedly connected to the upper end of each dredging claw, and both ends of the positioning component are rotatably connected to the adapter slot. A linkage component is movably sleeved inside the dredging rod, with its side connected to the positioning component. The upper end of the linkage component extends to the top of the dredging rod and is fixedly connected to a control handle. The linkage component moves along the axis of the dredging rod and drives the dredging claws to swing through the positioning component.

[0007] Preferably, the outer surface of the sludge removal claw is smooth, the outer circumferential diameter of the upper end of the sludge removal claw is larger than the outer circumferential diameter of its lower end, the sludge removal claw has a curved structure, and the upper end of the sludge removal claw is movably connected to the interior of the adapter groove through a positioning component.

[0008] Preferably, the lower end of the curved dredging claw is fitted to the side of the adapter groove cavity near the axis of the dredging rod, and the middle part of the curved dredging claw is fitted to the side of the adapter groove cavity away from the axis of the dredging rod.

The outer surface of the positioning shaft extends into the interior of the sludge removal rod on the side closest to the axis of the sludge removal rod.

[0010] Preferably, the linkage assembly includes a linkage rod that is movably inserted inside the sludge removal rod. The outer surface of the linkage rod is integrally formed with a plurality of evenly distributed transmission toothed rings. A gap is left between the outer surface of the transmission toothed rings and the inner wall of the sludge removal rod. The transmission toothed rings mesh with the positioning shaft.

[0011] Preferably, an adjusting connecting rod is fixedly connected to the top of the linkage rod, and the upper end of the adjusting connecting rod passes through the linkage rod and is fixedly connected to the bottom of the control handle.

[0012] Preferably, the outer surface of the adjusting connecting rod is threaded with an adjusting ring located between the sludge removal rod and the control handle. The adjusting ring moves with the adjusting connecting rod and contacts the top of the sludge removal rod.

Due to the setting of the adjusting connecting rod, this utility model can ensure that the linkage rod can move smoothly back and forth when the control handle is moved, under the restriction of the sludge removal rod.

Since the adjusting ring will abut against the sludge removal rod when it moves with the adjusting connecting rod, the relative movement range of the linkage assembly and the sludge removal rod can be realized by adjusting the position of the adjusting ring, thereby adjusting the expansion range of the sludge removal claw and ensuring that it can move back and forth within the sludge removal port.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1 to 4 As shown, this utility model provides a bridge drainage outlet dredging and anti-clogging device, comprising,

[0026] The dredging rod 1 has several evenly distributed adapter grooves 2 on its side. The lower end of the adapter grooves 2 extends to the bottom of the dredging rod 1. Several evenly distributed dredging claws 3 are movably installed inside the adapter grooves 2. The upper end of the dredging claws 3 is fixedly connected to a positioning component 4. The two ends of the positioning component 4 are rotatably connected to the adapter grooves 2. The dredging rod 1 has a linkage component 5 movably sleeved inside. The side of the linkage component 5 is connected to the positioning component 4. The upper end of the linkage component 5 extends above the dredging rod 1 and is fixedly connected to a control handle 6. The linkage component 5 moves along the axis of the dredging rod 1 and drives the dredging claws 3 to swing through the positioning component 4. Due to the setting of the dredging claws 3, under the restriction of the positioning component 4, the dredging claws 3 can swing and follow the dredging rod 1 to move back and forth through the linkage component 5 and the dredging rod 1, thereby achieving the purpose of unidirectional pushing of silt. Thus, under continuous operation, the effect of quickly and effectively clearing silt can be achieved.

[0027] The outer surface of the dredging claw 3 is smooth, and the outer diameter of the upper end of the dredging claw 3 is larger than that of the lower end. The dredging claw 3 has a curved structure. The upper end of the dredging claw 3 is movably connected to the inside of the adapter groove 2 through the positioning component 4. The lower end of the curved dredging claw 3 fits against the side of the inner cavity of the adapter groove 2 near the axis of the dredging rod 1, and the middle part of the curved dredging claw 3 fits against the side of the inner cavity of the adapter groove 2 away from the axis of the dredging rod 1. Due to the curved structure of the dredging claw 3, the pushing stability can be increased, and the situation of the pushed foreign objects slipping outward during the pushing process can be avoided. Due to the conical structure of the dredging claw 3, its insertion efficiency in removing sludge can be improved.

[0028] The positioning component 4 includes a transmission gear 41 fixedly sleeved on the upper end of the dredging claw 3. A positioning shaft 42 is fixedly sleeved on the outer surface of the transmission gear 41. The outer surface of the positioning shaft 42 extends into the interior of the dredging rod 1 on the side closest to the axis of the dredging rod 1.

[0029] The linkage component 5 includes a linkage rod 51 that is movably inserted inside the sludge removal rod 1. The outer surface of the linkage rod 51 is integrally formed with several evenly distributed transmission toothed rings 55. There is a gap between the outer surface of the transmission toothed rings 55 and the inner wall of the sludge removal rod 1. The transmission toothed rings 55 mesh with the positioning shafts 42. Due to the setting of the transmission toothed rings 55, when they move back and forth with the linkage rod 51, they can simultaneously drive several positioning shafts 42 to rotate, thereby causing several sludge removal claws 3 to swing under the restriction of the transmission gears 41.

[0030] The top of the linkage rod 51 is fixedly connected to an adjusting connecting rod 52. The upper end of the adjusting connecting rod 52 passes through the linkage rod 51 and is fixedly connected to the bottom of the control handle 6. The outer surface of the adjusting connecting rod 52 is threaded with an adjusting ring 7 located between the sludge removal rod 1 and the control handle 6. The adjusting ring 7 moves with the adjusting connecting rod 52 and contacts the top of the sludge removal rod 1. Due to the setting of the adjusting connecting rod 52, under the restriction of the sludge removal rod 1, it can be ensured that the linkage rod 51 can move smoothly back and forth when the control handle 6 is moved. It also facilitates the movement of the adjusting ring 7. Since the adjusting ring 7 will abut against the sludge removal rod 1 when it moves with the adjusting connecting rod 52, the relative movement range of the linkage assembly 5 and the sludge removal rod 1 can be realized by adjusting the position of the adjusting ring 7, thereby adjusting the expansion range of the sludge removal claw 3 and ensuring that it can move back and forth within the sludge removal port.

[0031] Among them, the bottom of the linkage rod 51 is fixedly connected to the limiting connecting rod 53. The lower end of the limiting connecting rod 53 passes through the sludge removal rod 1 and is fixedly connected to the drag-reducing cone 54. The drag-reducing cone 54 moves with the limiting connecting rod 53 and contacts the bottom of the sludge removal rod 1. The drag-reducing cone 54 is inverted cone-shaped and fits tightly with the sludge removal rod 1. Due to the setting of the drag-reducing cone 54, it can be ensured that it can fit with the bottom of the sludge removal rod 1 when it moves upward with the limiting connecting rod 53, avoiding the situation where the drag-reducing cone 54 significantly increases the resistance when the sludge removal rod 1 and the sludge removal claw 3 move upward as a whole. When moving downward, the drag-reducing cone 54 can also effectively reduce the pushing resistance.

[0032] Among them, the outer diameter of the linkage rod 51 is larger than the outer diameter of the adjusting connecting rod 52 and the limiting connecting rod 53. The adjusting connecting rod 52 and the limiting connecting rod 53 are movably sleeved on the upper and lower ends of the dredging rod 1. The outer diameter of the upper end of the resistance reducing cone 54 is the same as the outer diameter of the dredging rod 1.

[0033] Working principle and usage process of this utility model:

[0034] Adjust the maximum range of the lower end of the dredging claw 3 after it is extended, according to the inner diameter of the dredging opening, so that the distance between the lower end of the claw and the axis of the dredging rod 1 is less than the radius of the dredging opening;

[0035] Specifically, by rotating the adjusting ring 7 to move it up and down along the surface of the adjusting connecting rod 52, the distance that the control handle 6 drives the adjusting connecting rod 52 to reciprocate within the sludge removal rod 1 can be changed, thereby changing the reciprocating range of the linkage rod 51, so that the range of reciprocating swing of the sludge removal claw 3 is smaller than the inner diameter of the sludge removal port.

[0036] Then, grasp the control handle 6 and insert the lower end of the dredging rod 1 and the resistance-reducing cone 54 into the dredging port. Pulling the control handle 6 back and forth will restrict the movement of the dredging rod 1 under the resistance of the blockage, thereby causing the control handle 6 to move back and forth relative to the dredging rod 1. This allows the control handle 6 to drive the linkage rod 51, the limit connecting rod 53, the resistance-reducing cone 54, and the transmission gear ring 55 to move back and forth along the axis of the dredging rod 1 through the adjusting connecting rod 52. During this process, the transmission gear 41 restricts the movement of the transmission gear 41. The toothed ring 55 drives the sludge removal claw 3 through the positioning shaft 42, causing the lower end of the sludge removal claw 3 to swing back and forth around its upper end. Under the restriction of the sludge removal rod 1, when the upper and lower ends of the linkage rod 51 abut against the two ends of the inner cavity of the sludge removal rod 1, the sludge removal rod 1 can move a small distance with the control handle 6, so that the sludge removal claw 3, after swinging and unfolding, can move along the sludge removal opening with the sludge removal rod 1. Due to the reciprocating swing of the sludge removal claw 3, the sludge can be pushed out in one line to achieve the purpose of rapid sludge removal and unblocking.
