Description

Technical Field

[0001] This invention belongs to the field of water conservancy facilities technology, specifically a drainage device for water conservancy construction and its usage method. Background Technology

[0002] During the construction of water conservancy projects, large amounts of water can easily accumulate in areas such as foundation pits, river channels, and construction work surfaces. If the water cannot be drained in time, it will directly affect the progress of water conservancy construction, reduce construction efficiency, and may even soak the construction foundation, erode the construction structure, and cause safety hazards such as foundation settlement and slope collapse. Therefore, drainage is an indispensable core process in water conservancy construction, and the performance of drainage devices directly determines the safety and efficiency of water conservancy construction.

[0003] Currently, the drainage pipes used in water conservancy construction still have some shortcomings in use: First, the water accumulation environment at water conservancy construction sites is complex, with a large amount of impurities such as leaves, weeds, silt, and gravel mixed in with the water flow. Conventional drainage pipes only have a simple water flow function and lack impurity treatment structures. Impurities are very easy to accumulate and block at pipe bends and inside the pipes, which will not only greatly reduce drainage efficiency, but also corrode the pipes and shorten the service life of drainage devices over a long period of time. Secondly, traditional drainage devices have fixed drainage power, relying solely on natural water flow drop or fixed-power water pumps for drainage. When the water volume at the construction site is small and the water flow rate is slow, the water transport power inside the pipe is insufficient, the water drainage efficiency is greatly reduced, and water retention is likely to occur. This cannot meet the construction requirements for rapid drainage and seriously restricts the progress of subsequent construction procedures.

[0004] Third, the existing drainage pipe installation structure is relatively simple, mostly relying on simple brackets for fixed-point support. The height and angle of the support structure cannot be adjusted, resulting in extremely poor adaptability. It cannot adapt to the uneven ground surface and the differences in construction and installation distances and heights at the construction site. Summary of the Invention

[0005] The purpose of this invention is to address the above-mentioned problems. This invention provides a drainage device for water conservancy construction and its usage method, which solves the problems of conventional drainage pipes having only a simple water flow function and lacking a structure for handling impurities. Impurities are easily accumulated and blocked at pipe bends and inside the pipes, and when the water flow in the drainage pipes is insufficient, the efficiency of draining water is greatly reduced, and water stagnation is likely to occur.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a drainage device for water conservancy construction and its method of use, including a connecting bend; The main body of the connecting bend is an L-shaped structure. Connecting flanges are welded to the outside of the two ends of the connecting bend. A through pipe is fixedly installed on the upper end face of the middle bent part of the connecting bend. The inner end face of the tube is threaded, and a cover plate is provided inside the tube. The outer end face of the lower part of the cover plate is threaded, and the lower part of the cover plate is threadedly connected to the inside of the tube. A first motor is fixedly installed on the upper end face of the cover plate, and a first drive shaft is connected to the lower end face of the first motor. The first drive shaft is located inside the connecting bend. Two cutters are mounted on the surface of the first drive shaft, and blades are also mounted on the surface of the first drive shaft, with the blades located between the two cutters; A second motor is fixedly installed on the outer end face of the connecting bend. A second drive shaft is connected to the front end face of the second motor. The second drive shaft is located inside the connecting bend. A fan blade is installed on the outer end face of the second drive shaft. The outer end face of the fan blade has an arc-shaped structure.

[0007] Furthermore, two sets of connecting screws are symmetrically installed on the outer end face of the connecting bend, and a semi-circular collar is sleeved on the outside of the connecting bend, with the inner end face of the collar fitting against the outer end face of the connecting bend.

[0008] Furthermore, a connecting plate is installed on the upper and lower end faces of the collar, and the surface of the connecting plate is evenly provided with connecting holes. The two connecting plates are connected by bolts.

[0009] Furthermore, two through holes are formed in the middle of the surface of the collar, and the connecting screw connecting the outer end of the bent pipe is engaged in the through holes on the surface of the collar, and a nut is connected to the surface of the connecting screw.

[0010] Furthermore, an inclined fixing post is welded to the outer end face of the collar, the fixing post has a device groove inside, and two locking holes are opened on the surface of the fixing post.

[0011] Furthermore, a sliding plate is slidably connected inside the device groove. The surface of the sliding plate is evenly provided with through holes. The pins are inserted into the locking holes and the through holes in sequence to fix the sliding plate in the device groove inside the fixing column.

[0012] Furthermore, the blade body has a spiral structure, and the cutter and blade are located at the bend of the connecting pipe.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The surface of the first drive shaft is equipped with spiral blades and two cutters. When the water flows through the connecting bend, the first motor drives the cutters and blades on the surface of the first drive shaft to rotate. When the two cutters rotate, they can cut and crush the leaves and other impurities in the water flow. There are spiral blades between the two cutters. When the blades rotate, they can rotate the impurities at the bottom of the connecting bend to the upper position, so that the cutters at the upper position can also cut the leaves in the water flow again.

[0014] 2. The second motor is fixedly installed on the outer end face of the connecting bend. When the water flow inside the drain pipe is slow, the second motor can be turned on. The second motor can drive the fan blades on the surface of the second drive shaft to rotate. When rotating, it will generate a strong water flow thrust, which will quickly push the water flow that has been pulverized by the cutter to the pipe outlet to complete the drainage operation.

[0015] 3. The fixed column has a device groove inside, and a sliding plate is slidably connected inside the device groove. The sliding plate can slide up and down inside the device groove to adjust the extension length according to the installation height and support distance requirements of the construction site. After adjustment, the pin is inserted through the locking hole on the surface of the fixed column and the through hole on the surface of the sliding plate to lock the position of the sliding plate inside the device groove, so as to realize the flexible adjustment of the device support height and support angle, allowing the device to adapt to uneven construction sites.

[0026] The specific usage and function of this embodiment: In this invention, the main body of the connecting bend 1 is an L-shaped structure. Each of the two ends of the connecting bend 1 is provided with a connecting flange 101, which can be used to connect with other drain pipes to change the drainage direction.

A connecting screw 102 is fixedly installed on the outside of the connecting bend 1, and the connecting screw 102 engages with the through holes 502. 2. Inside, after the worker tightens the nut on the surface of the connecting screw 102, the stability of the collar 5 outside the connecting bend 1 is improved, preventing the collar 5 from loosening and shifting during operation. The fixed column 6 has a device groove 601 inside, and a sliding plate 7 is slidably connected inside the device groove 601.
