Description

Technical Field

[0001] This utility model relates to the technical field, specifically to a robot for preventing blockages and clearing silt from drainage pipes of highway bridges. Background Technology

[0002] Drainage pipes of highway bridges (such as drain pipes and transverse drainage pipes) are exposed to the natural environment for a long time and are easily blocked by the accumulation of debris such as mud, fallen leaves, and garbage, resulting in poor drainage. This can lead to bridge structural corrosion, road surface icing, and even affect bridge safety. Traditional manual dredging methods are inefficient, costly, and pose safety hazards. Therefore, developing an automated, efficient, and adaptable drainage pipe dredging robot has significant engineering application value.

[0003] A pipeline dredging robot, disclosed in CN109372095A, comprises a shell, rollers, a drive shaft, a motor, and a connecting flange. The motor is fixedly connected to the outer wall of the shell, and the connecting flange is embedded in the side wall of the shell. The output end of the motor is connected to the drive shaft, and the two ends of the drive shaft are connected to rollers. One end of the casing is fixedly connected to one end of the connecting column, and the first stepper motor is installed at the other end of the casing. A lighting flashlight parallel to the casing is fixedly connected to the mounting base. A camera is installed below one end of the lighting flashlight. The other end of the connecting column is fixedly connected to the dredging box, and a sewage pump is installed inside the dredging chamber. This invention breaks up and discharges blockages, preventing secondary blockages, while maintaining the stability of the robot body during dredging. It achieves good dredging effect, high efficiency, and strong practicality.

[0004] The device uses a motor to drive a churning paddle to break up blockages. While this method can achieve the desired breaking effect, it requires a large amount of electricity due to its motor drive, and the motor is placed inside the pipe where it is susceptible to moisture and water ingress, which may damage the motor.

[0005] To address the aforementioned issues, we have made innovative designs based on the existing structure of the anti-clogging and dredging robot for highway bridge drainage pipes. Utility Model Content

[0006] The purpose of this utility model is to provide a dredging robot for preventing blockages in drainage pipes of highway bridges, in order to solve the problems mentioned in the background art. Although the existing devices can achieve the breaking effect, they rely on motor drive and require a lot of electricity. Moreover, the motor is placed inside the pipe and is prone to moisture and water ingress, which may cause damage to the motor.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a dredging robot for preventing blockages in drainage pipes of highway bridges, comprising a body, guide wheels, a dredging plate, a rear push plate, an air pipe connector, a rotating shaft, a breaker, and a piercing head. Guide wheels are installed at equal angles on the outer side of the body, and a dredging plate is provided at the front end of the body. A rear push plate is provided at the rear end of the body, and an air pipe connector is fixedly connected to the outer side of the rear push plate. A rotating shaft is rotatably connected to the inner side of the body, and breaker is installed at equal intervals on the outer side of the rotating shaft. A piercing head is fixedly connected to the top of the rotating shaft.

[0008] Preferably, the puncture head has a cone-shaped structure when viewed from the front.

[0009] Preferably, a sliding rod is fixedly connected to the tail end of the machine body, and a rear push plate is slidably connected to the outer side of the sliding rod, and a first telescopic spring is connected between the rear push plate and the machine body.

[0010] Preferably, a first inclined plate is fixedly connected to the outer side of the rear push plate.

[0011] Preferably, a connecting plate is fixedly connected to the tail end of the machine body, and a guide rod is slidably connected to the inner side of the connecting plate, and a second telescopic spring is connected between the end of the guide rod and the connecting plate.

[0012] Preferably, a rack is fixedly connected to the outer side of the guide rod, and a second inclined plate is fixedly connected to the side end of the rack.

[0013] Preferably, the second bevel plate and the first bevel plate are in a front-to-back fit.

[0014] Preferably, a gear is fixedly connected to the tail end of the rotating shaft, and the gear meshes with the outer rack.

[0015] Compared with the prior art, the beneficial effect of this utility model is that the anti-clogging and dredging robot for highway bridge drainage pipes is equipped with:

[0016] 1. Dredging Structure: When dredging the inside of a pipe is required, the machine body is first placed inside the pipe, and the guide wheels evenly distributed on the outside are attached to the inner wall of the pipe. Then, the output end of the air pump is connected to the air pipe connector through the air pipe to drive the air pump. The air pressure generated will push the rear push plate forward along the inside of the pipe, thereby pushing the dredging plate at the front of the machine body to push the sludge accumulated inside the pipe to the end of the pipe, thus achieving the effect of dredging the pipe.

[0017] Furthermore, a piercing head is provided at the front end of the rotating shaft. The piercing head can pierce the blockage sludge, thereby allowing easily discharged objects such as sewage to be discharged from the piercing point, reducing the pressure on the sludge removal plate.

[0018] 2. Crushing Structure: When the sludge removal plate encounters a blockage point while being pushed forward, the machine body experiences forward resistance. At this time, the rear push plate, under air pressure, compresses the first telescopic spring and moves towards the machine body. As the rear push plate moves towards the machine body, its outer first inclined plate engages with its outer second inclined plate, thereby pushing the second inclined plate to the left. The leftward movement of the second inclined plate causes the rack to move along with it and compresses the second telescopic spring. As the rack moves, the gear meshing with the rack rotates, thereby driving the rotating shaft to rotate inside the machine body. This causes the crusher at the top of the rotating shaft to crush the sludge blocking the inside of the pipe, clearing the blockage point and facilitating the cleaning of the sludge in the pipe.

[0019] Furthermore, once the blockage is cleared, the machine body loses forward resistance and moves forward. The first telescopic spring loses its compressive force and resets, causing the crusher to rotate in the opposite direction, making it easier to clear the blockage next time.

[0026] 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.

[0027] Please see Figures 1-5 This utility model provides a technical solution: a robot for preventing blockage and clearing silt from drainage pipes of highway bridges, comprising:

[0028] Example 1: As Figures 1-4 The present invention provides a technical solution: a dredging robot for preventing blockages in drainage pipes of highway bridges, comprising: a body 1, guide wheels 2, dredging plates 3, a rear push plate 4, an air pipe connector 5, a rotating shaft 6, a breaker 7, and a piercing head 8. Guide wheels 2 are installed at equal angles on the outer side of the body 1, and a dredging plate 3 is provided at the front end of the body 1. A rear push plate 4 is provided at the rear end of the body 1, and an air pipe connector 5 is fixedly connected to the outer side of the rear push plate 4. A rotating shaft 6 is rotatably connected to the inner side of the body 1, and breaker 7 is installed at equal intervals on the outer side of the rotating shaft 6. A piercing head 8 is fixedly connected to the top of the rotating shaft 6.

[0029] The puncture head 8 has a cone-shaped structure when viewed from the front.

[0030] This device is suitable for pipelines with short travel distances;

[0031] When this structure needs to clean the inside of the pipe, the machine body 1 is first placed inside the pipe, and the guide wheels 2, which are evenly distributed on the outside, are attached to the inner wall of the pipe. Then, the output end of the air pump is connected to the air pipe connector 5 through the air pipe to drive the air pump. The air pressure generated will push the rear push plate 4 forward along the inside of the pipe, so that the cleaning plate 3 at the front end of the machine body 1 pushes the sludge accumulated inside the pipe to the end of the pipe, thereby achieving the effect of cleaning the pipe. The front end of the rotating shaft 6 is equipped with a piercing head 8, which can pierce the blocked sludge, so that sewage and other easily discharged objects can be discharged from the piercing point, reducing the pressure of the cleaning plate 3 pushing.

[0032] Example 2: Figures 1-4 The present invention provides a technical solution: a dredging robot for preventing blockages in drainage pipes of highway bridges, comprising: a sliding rod 9 fixedly connected to the tail end of the body 1, and a rear push plate 4 slidably connected to the outer side of the sliding rod 9, and a first telescopic spring 10 connected between the rear push plate 4 and the body 1; a first inclined plate 11 fixedly connected to the outer side of the rear push plate 4; a connecting plate 12 fixedly connected to the tail end of the body 1, and a guide rod 13 slidably connected to the inner side of the connecting plate 12, and a second telescopic spring 14 connected between the end of the guide rod 13 and the connecting plate 12; a rack 15 fixedly connected to the outer side of the guide rod 13, and a second inclined plate 16 fixedly connected to the side end of the rack 15; the second inclined plate 16 and the first inclined plate 11 are in a front-to-back engagement state; a gear 17 fixedly connected to the tail end of the rotating shaft 6, and the gear 17 meshes with the outer rack 15;

[0033] When the sludge removal plate 3 is pushed forward and encounters a blockage, the machine body 1 will experience forward resistance. At this time, the rear push plate 4 will compress the first telescopic spring 10 under air pressure and move towards the machine body 1. When the rear push plate 4 moves towards the machine body 1, its outer first inclined plate 11 will engage with the outer second inclined plate 16, thereby pushing the second inclined plate 16 to the left. The leftward movement of the second inclined plate 16 will drive the rack 15 to move along with it and compress the second telescopic spring 14. As the rack 15 moves, the gear 17 meshing with the rack 15 will rotate, thereby driving the rotating shaft 6 to rotate inside the machine body 1. This causes the crusher 7 at the top of the rotating shaft 6 to crush the sludge blocking the inside of the pipe, clearing the blockage and facilitating the cleaning of the pipe sludge. Once the blockage is cleared, the machine body 1 loses forward resistance and moves forward. The first telescopic spring 10 loses its squeezing force and resets, causing the crusher 7 to rotate in the opposite direction, facilitating the next cleaning of the blockage.
