Description

Technical Field

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

[0002] In the field of water conservancy engineering, maintaining the smooth flow and health of water bodies is crucial for ensuring the rational use of water resources, flood control and drainage, and ecological balance. Over time, natural factors (such as siltation and water erosion) and human activities (such as industrial discharge and domestic sewage) can lead to varying degrees of siltation in water pipelines. Severe siltation significantly affects the normal operation of water conservancy facilities, reduces flood discharge capacity, and causes serious damage to aquatic ecosystems, leading to water quality deterioration and reduced biodiversity. Therefore, regular dredging has become an important task in the maintenance and management of water conservancy projects.

[0003] Dredging equipment used in water conservancy projects plays an indispensable role as a crucial tool for solving the problem of siltation in water pipelines. Currently, the most commonly used dredging equipment is the cutter suction dredging system. In actual pipeline environments, silt often adheres firmly to the inner wall of the pipe, especially long-term accumulated silt, which may undergo chemical reactions with the pipe wall or become tightly bonded due to water penetration. Currently, there is inevitably a certain gap between the cutter suction dredging equipment and the inner wall of the pipe. During the dredging process, the cutter suction dredging equipment can only work on the area reached by its blades. Areas closer to the pipe wall, especially the gaps between the auger blades and the pipe wall, cannot be effectively covered by the auger, making it difficult to remove silt and dirt from these areas. Utility Model Content

[0004] In order to overcome the shortcomings of existing technologies where silt and dirt in the pipe wall area are difficult to clean, this utility model provides a dredging device for water conservancy engineering construction.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a dredging device for water conservancy engineering construction, including a rotating shaft, on which auger blades are installed, a pipe wall dredging component is provided at the front end of the rotating shaft, and a drive motor is connected to the rear end of the rotating shaft. The pipe wall dredging component includes a round shaft, one end of which is provided with several front hinge seats, each front hinge seat is hinged with a first connecting rod, the top of the first connecting rod is connected with a scraper, the middle of the first connecting rod is hinged with a second connecting rod, a ring sleeve is sleeved on the round shaft, the ring sleeve is provided with several rear hinge seats corresponding to the front hinge seats, the second connecting rod is hinged on the rear hinge seats, the ring sleeve is provided with several screw holes, and each screw hole is provided with a fastening bolt.

[0006] As a further improvement of this utility model, a sludge removal transition pipe is provided on the drive motor.

[0007] As a further improvement of this utility model, a telescopic sleeve is provided on the dredging transition pipe.

[0008] As a further improvement of this utility model, the round shaft is inserted into the rotating shaft and fastened by fixing bolts.

[0009] As a further improvement of this utility model, the scraping surface of the scraper is provided with a removable wear-resistant layer.

[0010] As a further improvement of this utility model, the drive motor is a waterproof motor.

[0011] As can be seen from the above technical solutions, the beneficial effects of this utility model are as follows: In this solution, by using the auger blades to transport the sludge at the bottom of the pipe and the pipe wall cleaning component to scrape the sludge from the inner wall of the pipe, a comprehensive and three-dimensional cleaning of the inside of the pipe is achieved, which effectively solves the problem that traditional cleaning equipment is difficult to clean the inner wall of the pipe, greatly improves the thoroughness of the cleaning, can significantly restore the water flow capacity of the pipe, and ensure the normal water conveyance function of the water conservancy pipeline.

[0017] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0018] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model discloses a dredging device for water conservancy engineering construction, including a rotating shaft 1, with auger blades 2 installed on the rotating shaft 1, a pipe wall dredging component 3 at the front end of the rotating shaft 1, and a drive motor 4 connected to the rear end of the rotating shaft 1. The pipe wall dredging component 3 includes a round shaft 7, with a plurality of front hinge seats 8 at one end of the round shaft 7. Each front hinge seat 8 is hinged with a first connecting rod 9, with a scraper 10 connected to the top of the first connecting rod 9, and a second connecting rod 11 hinged to the middle of the first connecting rod 9. A ring sleeve 12 is sleeved on the round shaft 7, and a rear hinge seat 13 corresponding to the front hinge seat 8 is provided on the ring sleeve 12. The second connecting rod 11 is hinged to the rear hinge seat 13. A plurality of screw holes 14 are provided on the ring sleeve 12, and a fastening bolt 15 is provided on each screw hole 14.

[0019] When dredging is required on the water pipeline, the operator starts the drive motor 4, which in turn drives the connected shaft 1 to rotate. Since the shaft 1 is equipped with auger blades 2, the rotation of the shaft 1 causes the auger blades 2 to rotate synchronously. During rotation, the auger blades 2 utilize their spiral structure to continuously push the silt accumulated at the bottom of the pipeline forward. Similar to the working principle of a screw conveyor, as the auger blades 2 continue to rotate, the silt is gradually transported along the bottom of the pipeline to the designated discharge location, thus cleaning the silt at the bottom of the pipeline. Simultaneously, the pipe wall dredging assembly 3, located at the front end of the shaft 1, also begins to operate. The scraper 10 of the pipe wall dredging assembly 3, under the action of the linkage mechanism, makes close contact with the inner wall of the pipeline. Specifically, when the fastening bolts 15 on the ring sleeve 12 are loosened and the position of the ring sleeve 12 on the round shaft 7 is moved, the rear hinge seat 13 moves accordingly, driving the first linkage 9 to rotate via the second linkage 11, thereby changing the radial position of the scraper 10 to adapt to the inner walls of pipelines with different diameters. When the shaft 1 rotates, the scraper 10 will rotate around the shaft together, scraping the inner wall of the pipe and removing the sludge attached to the inner wall of the pipe. The scraped sludge will also be discharged from the pipe together with the sludge transported by the auger blades 2 at the bottom under the action of gravity or subsequent water flow.

[0020] The drive motor 4 is equipped with a dredging transition pipe 5, and the dredging transition pipe 5 is equipped with a telescopic sleeve 6. The dredging transition pipe 5 can be easily connected to other types of pipes or equipment according to different dredging project needs, such as connecting to a sludge storage device or directly connecting to an external transport pipeline. It provides a standardized connection interface, enhancing the compatibility and adaptability of the dredging equipment with other related facilities, making the construction of the entire dredging system more flexible and convenient. The telescopic sleeve 6 acts as an isolation barrier, allowing the sludge to flow in a relatively independent channel, reducing the erosion and wear of the drive motor 4 and surrounding structures by the sludge, extending the service life of the drive motor 4 and related equipment, and reducing equipment maintenance costs and replacement frequency.

[0021] The round shaft 7 is inserted into the rotating shaft 1 and secured with fixing bolts 16. This connection method is simple and reliable, ensuring the coaxiality between the round shaft 7 and the rotating shaft 1, enabling stable power transmission and ensuring that the pipe wall sludge removal component 3 and the auger blade 2 work synchronously and efficiently; it also facilitates disassembly and installation, making it convenient for equipment transportation, maintenance and replacement of parts, reducing the difficulty and cost of equipment maintenance.

[0022] The scraping surface of the scraper 10 is provided with a removable wear-resistant layer. The wear-resistant layer is made of high-strength wear-resistant rubber or hard alloy material and is fixedly connected to the scraper by bolts. When the wear-resistant layer is worn, it can be easily replaced.

[0023] The drive motor 4 is a waterproof motor, which improves its service life in underwater or humid environments. The shaft 1 is connected to the output shaft of the drive motor 4 by a coupling. The coupling is a flexible coupling, which can buffer the vibration generated during the start-up and operation of the drive motor and protect the equipment components.

[0024] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
