Description

Technical Field

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

[0002] Water conservancy projects are engineering projects constructed to control and regulate surface water and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits. They generally require the construction of different types of hydraulic structures such as dams, dikes, spillways, sluice gates, intakes, canals, ferries, raft channels, and fishways to achieve their objectives. When constructing hydraulic structures, it is generally necessary to guide the water flow through diversion devices to ensure that the construction area remains dry, thereby facilitating the smooth progress of water conservancy construction.

[0003] Based on the above, the inventors have discovered that existing diversion devices are generally laid directly below the riverbed to guide water flow through the construction area. Filter screens are installed at the inlet and outlet of the diversion device to filter debris and reduce clogging of the diversion pipe. However, debris accumulates on the outside of the filter screen, requiring frequent cleaning by construction workers; otherwise, blockages will occur, reducing water flow and hindering the diversion work. Frequent cleaning also increases the workload of construction workers. Therefore, in view of this, the inventors have researched and improved the existing structure to provide a diversion device for water conservancy projects, aiming to achieve a more practical purpose.

This solution is equipped with a self-cleaning cleaning component that uses the impact force of water flow as power to clean impurities filtered on the outside of the pipe, reducing the occurrence of blockage problems and ensuring the smooth operation of the flow guiding work. In addition, a filter component that is easy to install and remove is provided, which can perform secondary filtration inside the pipe to further reduce blockage problems. At the same time, it is convenient to centrally clean the filtered impurities. It is easy to use. A guide component is provided to limit and guide the movement of the cleaning component, ensuring the rotational stability of the cleaning component and extending the service life of the cleaning component.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A diversion device for water conservancy projects includes a guide tube, with an inlet head and an outlet head fixedly connected to both ends of the guide tube, a sealing cap threaded to the top of the inlet head, a rotating shaft movably connected to the middle of the sealing cap, an impeller movably connected to the bottom of the rotating shaft, a filter mechanism disposed below the impeller, a pair of first limiting rings fixedly connected to the outer side of the rotating shaft, and a set of cleaning plates fixedly connected to the top of the rotating shaft.

[0009] The filtration mechanism includes a support ring, a filter screen is snapped onto the top of the support ring, and a second limiting ring is fixedly connected to the top surface of the filter screen.

[0010] Furthermore, the inlet head and the outlet head are symmetrically arranged, and a number of filter holes are opened on the side of the inlet head and the side of the outlet head.

[0016] 3. Beneficial Effects

[0017] Compared with existing technologies, the advantages of this utility model are:

[0018] (1) In this scheme, after the water flows into the inlet head, it impacts the impeller and generates rotational power, which drives the rotating shaft to rotate. The cleaning plate rotates synchronously with the rotating shaft to clean the debris that is filtered and adhered to the outer surface of the inlet head. Compared with the existing technology, the self-cleaning cleaning component is set up, which uses the impact force of the water flow as power to clean the impurities filtered on the outside of the pipe, reducing the occurrence of blockage problems and ensuring the smooth progress of the flow diversion work.

[0019] (2) By setting up a filtration mechanism, the filter screen can perform secondary filtration of impurities that have penetrated into the pipe. By rotating the sealing cover to separate from the water inlet head, the impeller and filter screen can be removed from the water inlet head, and the components can be replaced and cleaned. Compared with the existing technology, the filter components are set up to be easy to install and remove, and secondary filtration can be performed inside the pipe, further reducing the clogging problem. At the same time, it is convenient to clean the filtered impurities in a concentrated manner, making it easy to use.

[0020] (3) By setting a first limiting ring in conjunction with a ball bearing to limit and guide the rotating shaft, and a second limiting ring in conjunction with a ball bearing to limit and guide the impeller, the rotational stability of the rotating shaft and the impeller is guaranteed. Compared with the prior art, the setting of the guiding component plays the role of limiting and guiding, ensuring the rotational stability of the cleaning component and extending the service life of the cleaning component.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0027] Example:

[0028] Please see Figure 1-4A diversion device for water conservancy projects includes a conduit 1, with an inlet head 2 and an outlet head 3 fixedly connected to both ends of the conduit 1, a sealing cap 4 threadedly connected to the top of the inlet head 2, a rotating shaft 5 movably connected to the middle of the sealing cap 4, an impeller 6 movably connected to the bottom of the rotating shaft 5, a filter mechanism 7 provided below the impeller 6, a pair of first limiting rings 8 fixedly connected to the outer side of the rotating shaft 5, and a set of cleaning plates 9 fixedly connected to the top of the rotating shaft 5.

[0029] The filter mechanism 7 includes a support ring 12, a filter screen 11 is snapped onto the top of the support ring 12, and a second limiting ring 13 is fixedly connected to the top surface of the filter screen 11. The filter mechanism 7 is provided to improve the filtration effect of the pipeline.

[0030] See Figure 1 The inlet head 2 and outlet head 3 are symmetrically arranged, and several filter holes are opened on the side of both the inlet head 2 and the side of the outlet head 3. The guide pipe 1 is laid below the riverbed of the river channel, so that the inlet head 2 and outlet head 3 are located at the two ends of the river channel, and both the inlet head 2 and outlet head 3 are located above the riverbed. The water flows into the inside of the guide pipe 1 through the inlet head 2 and then flows out through the outlet head 3, completing the diversion work and keeping the construction area dry.

[0031] See Figure 2 The top of the rotating shaft 5 passes through the top of the sealing cover 4, and the impeller 6 faces the top of the water inlet head 2. After the water flows into the water inlet head 2, it impacts the impeller 6, generating a rotational driving force that drives the rotating shaft 5 to rotate.

[0032] See Figure 3 The first limiting ring 8 is located below the sealing cover 4 and is movably connected to the sealing cover 4. The first limiting ring 8 ensures the rotational stability of the rotating shaft 5.

[0033] See Figure 3 The cleaning plate 9 is located outside the water inlet head 2. The lower end of the cleaning plate 9 is tapered and is in contact with the outer surface of the water inlet head 2. The cleaning plate 9 rotates synchronously with the rotating shaft 5 to clean the debris that is filtered and adhered to the outer surface of the water inlet head 2.

[0034] See Figure 4 The support ring 12 is located inside the inlet head 2 and is fixedly connected to the inlet head 2. The second limiting ring 13 is located inside the impeller 6 and is movably connected to the impeller 6. The impeller 6 is limited by the second limiting ring 13 to ensure the rotational stability of the impeller 6.

[0035] See Figure 4A set of balls 10 are movably connected to both sides of the first limiting ring 8 and both sides of the second limiting ring 13. The balls 10 on both sides of the first limiting ring 8 are in contact with the inner surface of the sealing cover 4, and the balls 10 on both sides of the second limiting ring 13 are in contact with the inner surface of the impeller 6. The rotational resistance of the limiting ring is reduced by the balls 10.

[0036] In use: The guide pipe 1 is laid below the riverbed, with the inlet 2 and outlet 3 located at opposite ends of the river, both above the riverbed. Water flows into the guide pipe 1 through the inlet 2 and then exits through the outlet 3, completing the flow guidance and keeping the construction area dry. Impurities that penetrate into the guide pipe 1 are filtered a second time by the filter screen 11. After the water flows into the inlet 2, it impacts the impeller 6, generating rotational power that drives the rotating shaft 5 to rotate, and the cleaning plate 9... As the rotating shaft 5 rotates synchronously, it cleans the debris adhering to the outer surface of the inlet head 2. The first limiting ring 8, in conjunction with the ball bearing 10, limits and guides the rotating shaft 5. At the same time, the second limiting ring 13, in conjunction with the ball bearing 10, limits and guides the impeller 6, thereby ensuring the rotational stability of the rotating shaft 5 and the impeller 6 and enabling the cleaning work to proceed smoothly. When cleaning is required, the sealing cover 4 is rotated to separate from the inlet head 2, allowing the impeller 6 and the filter screen 11 to be removed from the inside of the inlet head 2, thus facilitating the replacement of the cleaning components.
