Description

Technical Field

[0001] The utility model relates to the technical field of pipeline cleaning, in particular to a municipal pipeline dredging device. Background Art

[0002] Pipeline dredging refers to dredging the pipeline, cleaning the sludge and other wastes inside the pipeline, and keeping it unblocked for a long time to prevent urban waterlogging. If the pipeline is not dredged regularly, it will cause sewage overflow, pollute the environment and bring trouble to people's lives. Generally, the inner wall of the pipeline of water conservancy projects is dredged.

[0003] The existing pipeline cleaning methods often use cleaning robots, which walk by the side legs fitting on the inner wall of the pipeline. However, for the existing cleaning robots in pipelines with different diameters, the walking wheels of the cleaning robots are not convenient to fit the inner walls of pipelines of various sizes, so it has a great impact on the work of the cleaning robots. Although the pipeline dredging devices proposed in the prior art can adapt to pipelines with different diameters for dredging when in use.

[0004] Therefore, based on the above problems, the utility model proposes a municipal pipeline dredging device. Content of the Utility Model

[0005] The purpose of the utility model is to solve the problem that the walking wheels of the existing cleaning robots are not convenient to fit the inner walls of pipelines of various sizes in pipelines with different diameters.

[0006] Therefore, according to the above problems, the utility model proposes a municipal pipeline dredging device, which includes a housing. A cleaning blade is provided at the front end of the housing, and a driving motor for starting the cleaning blade is fixedly installed inside the front end of the housing. The power output end of the driving motor is fixed with the cleaning blade. An adaptive mechanism for adapting to the internal diameter of the municipal pipeline is provided in the middle of the housing, and the adaptive mechanism makes the walking wheels of the dredging device fit the inner walls of municipal pipelines with different diameters.

[0007] Preferably, the adaptive mechanism includes: a connecting rod, a turntable, and a housing. A motor is fixedly installed inside the housing. The output shaft of the motor is fixedly connected with the connecting rod. The connecting rod is fixedly connected with two turntables, and the connection position is located at the center of the turntable. The inner wall of a bearing is nested outside the turntable, and the outer wall of the bearing is nested on the inner wall of the housing. A plurality of arc-shaped grooves are also provided in the middle of the turntable. The shape feature of the arc-shaped grooves is spiral outward. A limiting rod is placed inside the arc-shaped grooves. The limiting rod is rotatably connected with a supporting foot. A plurality of side grooves are provided on the outer side of the housing, and the supporting feet slide inside the side grooves.

[0008] Preferably, a bottom foot slides inside the supporting foot. The end of the bottom foot is connected with a walking wheel, and the walking wheel is driven to walk by a corresponding control motor. A spring is also provided at the connection between the bottom foot and the supporting foot. Advantageous Effects

[0009] When encountering pipes with different diameters, the motor can be controlled. The motor drives the connecting rod 201 and the turntable to rotate, so that its supporting feet expand outwards, making the supporting feet connect the bottom feet and the walking wheels fit against the inner wall of the pipe, realizing an adaptive mechanism for the internal diameter of the pipe.

[0010] At the same time, since a spring is also provided at the connection between the bottom feet and the supporting feet, when the pipe deforms into an ellipse, the spring elasticity can also be used to allow a certain height compensation of the bottom feet in the supporting feet, so that the bottom feet fit against the inner wall of the pipe.

[0015] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0016] Referring to Figures 1 to 3 , a municipal pipeline dredging device includes a housing 1. A cleaning blade 101 is provided at the front end of the housing 1. A driving motor for starting the cleaning blade 101 is fixedly installed inside the front end of the housing 1. An adaptive mechanism for adapting to the internal diameter of the municipal pipeline is provided in the middle of the housing 1. The adaptive mechanism makes the walking wheels of the dredging device fit against the inner walls of municipal pipelines with different diameters.

[0017] Preferably, the adaptive mechanism includes: a connecting rod 201, a turntable 202, a housing 1, a motor 2 fixedly installed inside. The output shaft of the motor 2 is fixedly connected to the connecting rod 201. The connecting rod 201 is fixedly connected to two turntables 202, and the connection position is located at the center of the turntable 202. The outer side of the turntable 202 is nested with the inner wall of a bearing 4, and the outer side of the bearing 4 is nested with the inner wall of the housing 1. Multiple arc-shaped grooves 203 are also provided in the middle of the turntable 202. The shape feature of the arc-shaped groove 203 is spirally outward. A limiting rod 3 is placed inside the arc-shaped groove 203. The limiting rod 3 is rotatably connected to a supporting foot 301. Multiple side grooves 102 are provided on the outer side of the housing 1. The supporting foot 301 slides inside the side groove 102. When encountering pipes with different diameters, the motor 2 can be controlled to drive the connecting rod 201 and the turntable 202 to rotate. When the turntable 202 rotates, it will drive the arc-shaped groove 203 of the turntable 202 to rotate. Since the limiting rod 3 is placed inside the arc-shaped groove 203, the limiting rod 3 will be driven to rotate. However, since the supporting foot 301 is slidably installed on the housing 1 and the supporting foot 301 is rotatably connected to the limiting rod 3, when the turntable 202 rotates, it will drive the supporting foot 301 and the limiting rod 3 connected to the supporting foot 301 to move outward.

[0018] Preferably, a bottom foot 302 slides inside the supporting foot 301. The end of the bottom foot 302 is connected to a walking wheel, and the walking wheel is driven to move by a corresponding control motor. A spring 303 is also provided at the connection between the bottom foot 302 and the supporting foot 301. Since the spring 303 is also provided at the connection between the bottom foot 302 and the supporting foot 301, when the pipe deforms into an oval shape, a certain height compensation can also be achieved for the bottom foot 301 in the supporting foot 301 through the elasticity of the spring 303, so that the bottom foot 302 fits the inner wall of the pipe.

[0019] Working principle:

[0020] When encountering pipes with different diameters, the motor 2 can be controlled to drive the connecting rod 201 and the turntable 202 to rotate. When the turntable 202 rotates, it will drive the arc-shaped groove 203 of the turntable 202 to rotate. Since the limiting rod 3 is placed inside the arc-shaped groove 203, the limiting rod 3 will be driven to rotate. However, since the supporting foot 301 is slidably installed on the housing 1 and the supporting foot 301 is rotatably connected to the limiting rod 3, when the turntable 202 rotates, it will drive the supporting foot 301 and the limiting rod 3 connected to the supporting foot 301 to move outward, thereby expanding the supporting foot 301 outward and making the supporting foot 301 connected to the bottom foot 302 and the walking wheel fit the inner wall of the pipe, realizing the adaptive mechanism for the internal diameter of the pipe;

[0021] Meanwhile, since a spring 303 is also provided at the connection between the bottom feet 302 and the support feet 301, when the pipeline deforms into an ellipse, the elasticity of the spring 303 can also be used to provide a certain height compensation for the bottom feet 301 in the support feet 301, so that the bottom feet 302 can fit against the inner wall of the pipeline.

[0022] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, shall be covered by the protection scope of the present invention.
