Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering pipeline dredging technology, specifically a water conservancy engineering pipeline dredging device. Background Technology

[0002] In water conservancy engineering systems, pipelines play a crucial role in the transportation, distribution, and discharge of water resources, serving as vital infrastructure for the normal operation of the water system. However, due to their long-term exposure to complex working environments, pipelines accumulate silt, sand, debris, and scale formed by chemical reactions. These deposits gradually reduce the flow cross-section of the pipeline, leading to partial or even complete blockages. Once a pipeline is blocked, it not only reduces the water conveyance capacity of the water conservancy project, causing water resource waste and imbalance in allocation, but in severe cases, it can also trigger pipeline ruptures, floods, and other safety accidents, posing a significant threat to water conservancy facilities, the surrounding environment, and the safety of people's lives and property.

[0003] A search revealed Chinese patent application number 202022439244.3, which discloses a pipe dredging device for water conservancy projects. This patent relates to the field of water conservancy engineering technology. The patent includes a base plate with casters fixedly connected to the four corners of its lower surface. A movable push rod is fixedly connected to the left side of the upper surface of the base plate. A counterweight is located on the left side of the upper surface of the base plate, and a housing is located on the right side of the upper surface of the base plate. A cooling fan is located in the middle of the left side of the housing. This patent utilizes the rotation of a second drive motor to rotate a threaded drill rod, which breaks up clumps of impurities inside the pipe, facilitating cleaning. The retraction of the second push rod motor's output drives a scraper to move the broken-up impurities from the pipe, thus speeding up pipe dredging and improving work efficiency.

[0004] Although the aforementioned patent breaks down impurities inside pipes, making it easier for users to clean them, in actual use, the patented unblocking mechanism can only perform a single rotation operation. When faced with hard blockages inside pipes, such as scale layers and large sand and gravel deposits, it is difficult to remove them by relying solely on the rotation of the threaded drill rod and the cleaning of the scraper, resulting in poor unblocking effect and thus reducing the practicality of the patent to some extent.

[0005] Therefore, the pipe unblocking device in the above patent needs to be modified to effectively prevent the problem that it can only achieve a single rotation operation, and that it is difficult to remove hard blockages in the pipe by relying on the rotation of the threaded drill rod and the cleaning of the scraper, resulting in poor unblocking effect.

[0033] The working principle and usage process of this utility model are as follows: When using this pipe dredging device to dredge water conservancy pipelines, firstly, the mobile vehicle 1 is moved to the inlet of the pipeline to be dredged. Then, the height of the rotating head 18 is adjusted according to the specific location of the pipeline. The electric lifting rod 2 is activated through the control terminal to extend or shorten it, adjusting the support shell 3 and the components above it to a suitable working height. Then, the stepper motor 4 inside the support shell 3 is activated to drive the support plate 5 to rotate, causing the rotating head 18 fixed on the support plate 5 to rotate horizontally, thereby aligning it with the inlet of the pipeline to be dredged. Then, the electric push rod 7 is activated to push the push plate 8 outward along the limiting strip 21 at the top of the support plate 5, thereby driving the extension strip 9, the connecting shell, and the rotating head 18 to move into the pipeline, allowing the rotating head 18 to contact the debris inside the pipeline for dredging. The output shaft of the starting geared motor 13 drives the crank 14 to rotate in the transmission groove 10 on the limit block 23. The crank 14 drives the slider 16 to slide in the sliding port 12 through the connecting rod 15, thereby converting the rotational motion of the geared motor 13 into the linear reciprocating motion of the slider 16. The slider 16 then drives the connecting shell and the rotating head 18 to reciprocate. At the same time, the rotating motor 17 in the connecting shell is started to drive the rotating head 18 to rotate at high speed. The spiral blades 19 on the surface of the rotating head 18 push the debris in the pipe to the pipe outlet. The crushing head 20 at the outer end of the rotating head 18 crushes the large pieces of debris encountered, thus achieving the purpose of pipe unblocking. During the unblocking process, the debris pushed out by the spiral blades 19 can be collected by the collection hopper 25. After the unblocking operation is completed, the debris in the collection hopper 25 can be disposed of in a unified manner.
