Description

Technical Field

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

[0002] Hydraulic engineering is a comprehensive discipline centered on water resource regulation, using engineering techniques to achieve goals such as flood control, water supply, irrigation, power generation, and ecological protection. Traditional technologies include hydraulic structures (such as dams, canals, and spillways), hydrological analysis (flood forecasting, runoff calculation), and irrigation and drainage systems (canal irrigation, drip irrigation, etc.). With technological advancements, modern hydraulic engineering integrates digital technologies, new materials, and optimization algorithms. Currently, hydraulic engineering is transforming towards green and sustainable development, emphasizing ecological protection (such as fishway design and sponge cities) and efficient resource utilization (reclaimed water and rainwater harvesting). In the future, the integration of artificial intelligence, climate change response, and new energy sources (such as pumped storage) will become key development directions, propelling hydraulic engineering towards a smarter and more environmentally friendly direction.

[0003] Drainage equipment is indispensable during the construction of water conservancy projects. Most water conservancy construction involves the drainage of rivers, lakes, and groundwater. These water bodies have complex environments with many impurities such as silt and aquatic plants. Water pumps are prone to clogging of the pump inlet during drainage, and impurities can be sucked into the pump, causing damage and affecting drainage efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is that existing equipment is difficult to handle in water conservancy construction in complex water environments with many impurities such as silt, aquatic plants and so on. During the drainage process, the water pump is prone to blockage of the water inlet, and the impurities are sucked into the water pump, which can easily damage the water pump and affect the drainage efficiency.

[0005] The technical solution adopted to solve the above-mentioned technical problems is to provide a drainage device for water conservancy construction.

[0006] Furthermore, the system includes a water pump, with a filter pipe fixedly connected to the front end of the water pump. A first fixed frame is provided on the front side of the filter pipe, and a first filter screen is fixedly connected inside the first fixed frame. A drive rod is rotatably connected to the middle of the first fixed frame, with a cutting disc fixedly connected to the front end of the drive rod. Several stirring blades are fixedly connected to the middle of the drive rod, and a second fixed frame is fixedly and rotatably connected to the rear end of the drive rod. A second filter screen is fixedly connected inside the second fixed frame.

[0007] Furthermore, a number of sliders are fixedly connected to the outer side of the second fixing frame, and a number of reserved slots are provided on the inner side of the filter tube. The sliders and reserved slots are correspondingly arranged. Reserved holes are provided on the upper and lower sides of the front part of the filter tube. The first filter screen and the cutting disc are correspondingly arranged. The drive rod, stirring blade, second fixing frame, and second filter screen are all located inside the filter tube.

[0008] The above technical solution filters out larger impurities in the water through the first and second filter screens, removes aquatic plants and other impurities from the first filter screen by the cutting disc, and uses stirring blades to break up larger mud and soil particles in the filter tube. This function can prevent impurities in the water from entering the water pump and causing damage to the water pump, and can also effectively prevent the water pump inlet from being blocked by impurities, thus affecting drainage efficiency.

[0009] Furthermore, a water pipe is fixedly connected to the top of the water pump, a drive device is provided inside the filter tube, and snap-fit ​​devices are provided on both the upper and lower sides of the front of the filter tube.

[0010] Furthermore, the driving device includes a drive motor located inside the filter tube. A drive gear is fixedly connected to the output end of the drive motor. A transmission gear meshes with the outside of the drive gear. The middle part of the transmission gear is fixedly connected to a drive rod, and the drive rod passes through the transmission gear. A protective shell is provided outside the drive gear and the transmission gear. The protective shell is rotatably connected to the drive rod.

[0011] The above technical solution uses a drive motor to drive a drive gear to rotate, which in turn meshes with a transmission gear to rotate, and the transmission gear drives a drive rod to rotate, thus providing power to the drive rod.

[0012] Furthermore, the snap-fit ​​device includes a snap-fit ​​block located on the rear side of the first fixed frame and fixedly connected to the first fixed frame. A movable block is snapped onto the top of the snap-fit ​​block, located inside the reserved hole. A connecting rod is fixedly connected to the center of the top surface of the movable block. A spring is fixedly connected to the top of the movable block, located on the outside of the connecting rod. The top of the spring is fixedly connected to the filter tube. A pull ring is rotatably connected to the top of the connecting rod.

[0013] With the above technical solution, the snap-fit ​​block is inserted into the reserved hole on the filter tube, so that the snap-fit ​​block abuts against the moving block and moves it upward. The snap-fit ​​block is fixed by the cooperation of the spring. When disassembling, the pull ring is pulled, and the moving block is moved upward through the connecting rod, so as to release the snap-fit ​​fixation between the moving block and the snap-fit ​​block.

[0014] The beneficial effects of this utility model are as follows:

[0015] This invention utilizes a water filter pipe at the front end of a water pump, with stirring blades, a first filter screen, a second filter screen, and a cutting disc inside the filter pipe. The first and second filter screens filter out larger impurities in the water, while the cutting disc scrapes away aquatic plants and other impurities from the first filter screen. The stirring blades break up larger clumps of mud and soil in the filter pipe. This function prevents impurities in the water from entering the water pump and causing damage, and also effectively prevents the water pump inlet from being blocked by impurities, thus affecting drainage efficiency.
