Description

Technical Field

[0001] This utility model relates to the field of pipe and channel cleaning, and in particular to a pipe and channel cleaning tool with an adjustable opening angle. Background Technology

[0002] Pipelines and channels, including pipes and canals, are an important component of urban and various types of infrastructure. Their core significance lies in enabling the orderly transportation and management of fluids (mainly water, including rainwater, sewage, and industrial wastewater). Pipelines are like "underground blood vessels," allowing various water flows in a regular manner, and are an indispensable infrastructure for maintaining the normal operation of cities and society.

[0003] Over time, pipe systems accumulate debris such as silt, fallen leaves, and plant roots. If not cleaned promptly, this reduces drainage capacity, leading to flooding during rainy weather and disrupting traffic and residents' lives. Furthermore, this debris contains large amounts of organic matter and pathogens; if blockages cause sewage overflows, it can pollute the soil, groundwater, and surrounding environment, breed mosquitoes, spread diseases, and endanger public health. Therefore, regular cleaning of pipe systems to ensure unobstructed drainage is crucial for maintaining their normal function and environmental safety, and also extends their lifespan.

[0004] There are many pipe cleaning tools on the market, which are relatively complex in structure and relatively expensive, and are not suitable for pipes of various sizes. Utility Model Content

[0005] This utility model proposes an adjustable-angle pipe and channel cleaning tool, which has a simple structure, low cost, and can be used for cleaning work in pipes and channels of different sizes.

[0006] To solve the above problems, this utility model relates to an adjustable-angle pipe cleaning tool, characterized in that it includes a main shaft, an extension arm, a screw, and a spring; the top end of the main shaft is provided with a traction hole, one end of the extension arm is movably connected to the main shaft; the extension arm is provided with at least two adjustment holes, the screw passes through the adjustment holes, and the two ends of the spring are respectively connected to the main shaft and the extension arm, the spring being mainly used to adjust the opening angle of the extension arm relative to the main shaft.

[0007] The adjustable-angle pipe cleaning tool is characterized in that two connecting blocks are provided at the top of the extension arm, and a protrusion is provided on the main shaft wall. The protrusion is placed inside the two connecting blocks and is hinged by a pin.

[0008] The adjustable-angle pipe cleaning tool is characterized in that a main shaft traction block is provided between the traction hole of the main shaft and the protrusion, and an extension arm traction block is provided at the upper end of the extension arm, with the two ends of the spring respectively connected to the main shaft traction block and the extension arm traction block.

[0009] The adjustable-angle pipe cleaning tool is characterized in that it has three extension arms, which are evenly distributed along the circumference of the main axis.

[0010] The adjustable-angle pipe cleaning tool is characterized in that it has four extension arms, which are evenly distributed along the circumference of the main axis.

[0011] The adjustable-angle pipe cleaning tool is characterized in that the screw is fixed to the extension arm by a nut.

[0012] The adjustable-angle pipe cleaning tool is characterized in that a roller is provided at the end of the extended arm away from the main shaft, and the roller is movably connected to the extended arm.

[0013] The aforementioned structure utilizes the tension of a spring, allowing the extension arm to self-adaptively open inside the pipe channel. Once open, different sized screws can be installed on the arm to support plant roots and fallen leaves, depending on site requirements. After connecting the rope to the traction hole at the top of the device, the device can be pulled within the pipe channel using various power sources such as manpower, vehicles, or geared motors, enabling cleaning of the entire pipe channel. Its structure is simple, low-cost, and adaptable to cleaning pipe channels of varying sizes. Attached Figure Description

[0014] Figure 1 : A schematic diagram of the structure of the adjustable-angle pipe cleaning tool of this utility model. Detailed Implementation

[0015] The adjustable-angle pipe cleaning tool of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0016] like Figure 1 As shown, an adjustable-angle pipe cleaning tool is characterized by comprising a main shaft 1, an extension arm 2, a screw 3, and a spring 4. The main shaft 1 has a traction hole 11 at its top end, and one end of the extension arm 2 is movably connected to the main shaft 1. Three or four extension arms 2 are evenly distributed along the circumference of the main shaft. If the main shaft is relatively thick, multiple extension arms 2 can be provided. The extension arm 2 has at least two adjustment holes 21, through which the screw 3 passes. When the pipe cleaning tool moves forward within the pipe, the screw 3 is mainly used for supporting plant roots and fallen leaves. Screws of different sizes can be installed on the extension arm 2 according to actual site requirements for supporting plant roots and fallen leaves. The two ends of the spring 4 are respectively connected to the main shaft 1 and the extension arm 2. The spring 4 can adaptively open inside the pipe, mainly used to adjust the opening angle of the extension arm 2 relative to the main shaft 1.

[0017] The top of the extender arm 2 is provided with two connecting blocks 22, and the shaft wall of the main shaft 1 is provided with a protrusion 12. The protrusion 12 is placed inside the two connecting blocks 22 and is hinged by a pin. This achieves the movable connection between the extender arm 2 and the main shaft 2.

[0018] A main shaft traction block 13 is provided between the traction hole 11 of the main shaft 1 and the protrusion 12. An extension arm traction block 23 is provided at the upper end of the extension arm 2. The two ends of the spring 4 are respectively connected to the main shaft traction block 13 and the extension arm traction block 23. The tensioning force of the spring 4 is used to realize the adaptive opening of the extension arm 2 inside the pipe channel, thereby adapting to pipe channels of different sizes.

[0019] The screw 3 is fixed to the extension arm 2 by a nut.

[0020] A roller 5 is provided at the end of the arm 2 away from the main shaft, and the roller 5 is movably connected to the arm 2. When the pipe cleaning tool is cleaning leaves or plant roots in the pipe, the roller 5 helps the pipe cleaning tool to move forward and adapts to the uneven inner wall of the pipe.

[0021] When pipe cleaning tools are needed, after connecting a rope to the traction hole 11 at the top of the main shaft 1, the cleaning tool can be pulled within the pipe using different power sources such as manpower, vehicles, or geared motors. The extension arm 2, utilizing the tensioning force of the spring 4, can adaptively open within the pipe to accommodate pipes of different sizes. After the extension arm 2 is opened, different sizes and numbers of screws 3 can be installed on it according to actual site needs for hanging plant roots and fallen leaves, enabling cleaning of the entire pipe section, especially difficult-to-remove foreign objects such as plant roots. Machine cleaning improves cleaning efficiency and reduces labor costs.

[0022] The preferred embodiments or specific implementations of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above-described embodiments and implementations. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the concept of the present invention.
