Description

Technical Field

[0001] This invention relates to the field of pipeline dredging equipment technology, and specifically to a novel dredging device suitable for underground sewage pipelines. Background Technology

[0002] Urban underground sewage pipes are prone to blockage due to the accumulation of silt and debris during long-term operation. Traditional dredging methods suffer from low efficiency, high operational difficulty, and significant damage to the pipes. Existing dredging equipment is mostly designed for vertical pipes and is difficult to adapt to the working environment of horizontal underground pipes. It also has drawbacks such as easy loss of control of the cutting tools, insufficient operational safety, and a limited range of compatible pipe diameters. Therefore, there is an urgent need for an efficient, safe, and highly adaptable underground sewage pipe dredging device. Summary of the Invention

[0003] The purpose of this invention is to provide a novel dredging device suitable for underground sewage pipes.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A novel drain cleaner includes a blade assembly, a power transmission assembly, and a protection and guiding assembly. The blade assembly includes 3-4 curved blades with a thickness of 2-4 mm, and the blades are fixedly mounted on a flexible steel wire shaft and a clamp. The power transmission assembly includes a central shaft, a flexible steel wire shaft, and a rubber tube sleeved on the outside of the flexible steel wire shaft. The protection and guiding assembly includes a protective disc that does not rotate with the shaft.

[0005] Specifically, the cutter head has a hollowed-out design on the front.

[0006] Specifically, a water seal ring, an oil seal ring, and a spiral steel strip sealing structure are sequentially provided at the connection between the central shaft and the flexible shaft, and a bearing is provided after the oil seal ring.

[0007] Specifically, the drain cleaner is also equipped with auxiliary wheels and a support for easy passage.

[0008] Specifically, the tail end of the drain cleaner is also equipped with a plug for charging.

[0009] The beneficial effects of this invention are as follows: This invention is adaptable to underground sewage pipes of different diameters and has excellent unblocking effects on both soft and hard blockages. The 25 cm diameter cutter head can maximize pipe unblocking. The circular structure effectively avoids cutter head runaway, pipe wall damage, and personnel injury accidents. The sealing components and flexible shaft design ensure stable power transmission, extend equipment service life, and adapt to complex underground working environments.

[0013] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0014] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0015] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0016] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0017] like Figures 1-2 As shown, a new type of sewer drain cleaner mainly consists of a cutter head assembly, a power transmission assembly, a protection and guiding assembly, and a clamp. The overall structure is compact and can be adapted to underground sewage pipes of different diameters.

[0018] Cutter head assembly The wire cutter head is designed with 3 blades 1. The blade 1 is 4mm thick and the curvature matches the forward rotation direction of the motor. The cutter head is divided by the central ring 2. The front cutter head is fixed on the flexible wire shaft 8 and the rear cutter head is fixed on the chuck.

[0019] Power transmission components Power unit: A 1kW motor is used. The motor should not be too large to avoid sudden jamming of the cutter head during operation, which could cause the machine body to flip violently. The motor is equipped with a gearbox to adjust the motor speed. A plug 13 is provided at the motor for temporary use as a connector.

[0020] Drive shaft: A flexible steel wire shaft 8 is selected, and the length can be customized according to the operation requirements. A rubber tube 14 is sleeved on the outside of the flexible steel wire shaft 8 to ensure that the cutter head is parallel to the tube wall and achieve stable forward cutting and unblocking.

[0021] Sealing structure: A water seal ring 4, a bearing 6 and an oil seal ring 5 are sequentially installed at the connection between the central shaft 7 and the flexible steel shaft 8, and the seal is reinforced by a spiral steel belt 9 to prevent sewage from seeping into the power unit.

[0022] Protection and guidance components Protective structure: It is connected to the chuck by fixing nut 10. During operation, it advances synchronously with the cutter head but does not rotate with the shaft, forming a physical barrier to prevent the cutter head from accidentally contacting the inner wall of the pipe or causing personal injury.

[0023] Working principle During operation, the cutter head assembly is installed on the front end of the flexible steel shaft 11 using the fixing nut 10, and the entire device is then inserted into the underground sewage pipe. After starting the motor, the flexible steel shaft 8 drives the cutter head to rotate clockwise, using the blade 1 to cut and break up the blockage. If the cutter head encounters severe jamming, the power should be cut off immediately to prevent the machine from tipping over and causing a safety accident. When the sewer pipe is too long, a temporary support 11 and auxiliary wheels 12 can be added to the bottom of the drain cleaner to facilitate its movement within the pipe. The operator can adjust the cutter head angle using the hook at the manhole opening to precisely handle blockages at different locations, achieving efficient and safe pipe dredging.

[0024] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0025] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
