Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a water conservancy project drainage device that prevents clogging. Background Art

[0002] The construction of water conservancy project channels is an inevitable requirement for the development of water conservancy projects. Water conservancy projects built to high standards can meet the basic needs of agricultural production and ensure the water required for crop growth, thereby improving agricultural production efficiency and quality. The construction of water conservancy project channels will be affected by many factors. During the construction of water conservancy project channels, every process link should be strictly controlled to ensure that the project quality meets the construction standards and prevent quality problems in the use of water conservancy project channels. Since the drainage channels of water conservancy projects inevitably have bends during the water delivery process, some difficult-to-construct sections should be avoided. Or the water is diverted in a directional manner. At the bend of the drainage channel of the water conservancy project, the water flow collides with the drainage channel and decelerates, causing the silt in the water body to accumulate inside the bend of the drainage channel. The silt needs to be scraped off regularly to prevent the bend of the drainage channel from being blocked. However, this requires first picking up the cover plate at the bend and resetting it after cleaning. The accumulated silt during the cleaning process is at the lower end of the drainage channel, so it needs to be scraped off with the help of an extended tool during cleaning. However, if the tool is too long, the force arm will increase, making it very difficult to scrape off the silt. Therefore, a water conservancy project drainage device is proposed.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-4 The utility model provides a technical solution: a water conservancy engineering drainage device for preventing clogging, comprising: a waterway 1, an inspection cover 2 is installed on the upper surface of the waterway 1, and a scraping mechanism is fixedly arranged inside the waterway 1, which is used to scrape the silt inside the waterway 1 and reduce the resistance encountered during scraping;

[0028] The scraping mechanism includes: a central column 3, the central column 3 is fixedly installed inside the waterway 1, and a functional column 4 is arranged at the upper end of the central column 3, and a mounting ring 5 is fixedly arranged on the lower surface of the functional column 4, and a limiting groove 6 is provided on the lower surface of the mounting ring 5, a buoyancy plate 7 is arranged on the lower end side surface of the central column 3, and a limiting rod 8 is fixedly arranged on the upper surface of the buoyancy plate 7, a rotating outer ring 9 is installed on the side surface of the functional column 4, and a scraper 10 is fixedly arranged on the side surface of the outer ring 9, and a scraper tooth 11 is fixedly arranged on the lower surface of the scraper 10;

[0029] The functional column 4 is threadedly connected to the central column 3 through the mounting ring 5, the limiting groove 6 is designed as a right-angle trapezoid, the buoyancy plate 7 is slidably connected to the central column 3 through the limiting rod 8, and the upper end of the limiting rod 8 is located inside the limiting groove 6, the scraping teeth 11 on the lower surface of the adjacent scraper 10 are staggered, and the lower end of the scraping teeth 11 is in contact with the inner bottom surface of the waterway 1;

[0030] When the outer ring 9 is driven to rotate, the outer ring 9 drives the scraper 10 to rotate to scrape the silt on the bottom surface of the waterway 1 through the scraper teeth 11. When water flows through the waterway 1, the water drives the buoyancy plate 7 and the limit rod 8 to move upward through buoyancy until the limit rod 8 moves to the inside of the limit groove 6. At this time, when the inspection cover 2 is opened and the functional column 4 is rotated, the inner surface of the right-angled side of the limit groove 6 fits with the upper end side surface of the limit rod 8 to prevent the rotation of the mounting ring 5, so that the functional column 4 cannot be separated from the installation with the center column 3.

[0031] A non-disassembly driving mechanism is provided inside the functional column 4 to facilitate pushing the scraper 10;

[0032] The non-disassembly driving mechanism includes: a static magnet 12, which is fixedly arranged on the inner surface of the outer ring 9, a sliding spiral rod 13 is arranged inside the functional column 4, and a moving magnet 14 is fixedly arranged on the upper end of the spiral rod 13, and a rotating pressure plate 15 is installed on the upper end of the moving magnet 14;

[0034] The moving magnet 14 and the static magnet 12 are arranged in a one-to-one correspondence, and the magnetic poles of the ends of the moving magnet 14 and the static magnet 12 facing each other are opposite;

[0035] When it is necessary to scrape off the sludge, the pressure plate 15 is first pressed downward by a tool. The pressure plate 15 is pressed to drive the screw rod 13 and the moving magnet 14 to slide downward. At this time, the screw rod 13 realizes self-rotation by engaging with the protrusion on the inner surface of the center column 3. During the rotation of the screw rod 13, the outer ring 9 is driven to rotate by the mutual attraction between the static magnet 12 and the moving magnet 14.
