Description

Technical Field

[0001] This utility model relates to the field of water conservancy pipeline technology, specifically to a water conservancy pipeline with automatic filter cleaning. Background Technology

[0002] Existing water pipes typically have filters at their inlets to prevent debris from entering. However, these filters easily become clogged with accumulated debris, affecting drainage efficiency. Therefore, a pipe system capable of automatically cleaning the inlet filters is needed.

[0003] In the prior art, to solve the above-mentioned technical problems, patent document CN215585674U discloses a water conservancy pipe for automatically cleaning filter screens. In this water conservancy pipe, one side of the drive gear is keyed to a connecting rod. The rotating connecting rod drives the drive gear to rotate, which in turn drives a large gear ring to rotate. The rotating large gear ring drives the cleaning rod and cleaning brush inside to clean the surface of the filter screen and pushes debris into a storage hopper for easy collection. However, in this technical solution, the connecting rod is installed inside the secondary pipe. This technical solution changes the transmission pipe structure, requiring significant adjustments to the existing pipe structure when installing it on an existing pipeline, resulting in poor adaptability. Furthermore, when fan blade maintenance is needed, the fan blades are inconvenient to remove from the secondary pipe. Utility Model Content

[0004] The main purpose of this utility model is to provide a water conservancy pipeline that can be easily maintained and has strong applicability for automatic cleaning of filter screens.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows: An automatic filter cleaning water pipe includes a main pipe, a branch pipe fixedly connected to the upper end of the main pipe, the branch pipe being perpendicular to the main pipe, a filter screen installed inside the upper end of the branch pipe, a splined rod rotatably connected to the center of the filter screen, a splined sleeve slidably fitted on the lower outer side of the splined rod, multiple fan blades evenly distributed and fixed on the lower outer circumference of the splined sleeve, a float concentrically fixed at the lower end of the splined sleeve, the lower end of the fan blades being fixedly connected to the upper end of the float, the splined rod penetrating the filter screen, a rotating rod fixed on the splined rod above the filter screen, the rotating rod being perpendicular to the splined rod, multiple brushes fixed at the lower end of the rotating rod, the brushes contacting the upper end of the filter screen.

[0006] Specifically, a retaining ring is concentrically fixed inside the upper end of the branch pipe, the lower end of the filter screen is blocked by the retaining ring, and multiple insert rods are fixed at the upper end of the retaining ring, which are inserted into the insertion holes of the filter screen.

[0007] Specifically, the upper end of the branch pipe is detachably and fixedly connected to a cover plate, the upper end of which has multiple elongated holes, and the lower end of the cover plate is concentrically fixed with a pressure ring, the lower end of which contacts the upper end of the filter screen.

[0008] Specifically, the upper end of the branch pipe is fixedly connected to the upper end of the cover plate by multiple connecting screws.

[0009] Specifically, the cover plate has a stepped hole in the center, which is concentric with the spline rod. The larger hole of the stepped hole is located at the top, and the smaller hole is located at the bottom. The upper end of the spline rod is located in the smaller hole of the stepped hole. A hexagonal prism is installed in the larger hole of the stepped hole, and the hexagonal prism is concentrically and fixedly connected to the upper end of the spline rod.

[0010] Specifically, the splined rod and the filter screen are rotatably connected via a waterproof bearing.

[0011] Specifically, the filter screen has slots on both sides, and two filter cylinders are fixed at the lower end of the filter screen, with the upper ends of the two filter cylinders communicating with the two slots respectively.

[0012] Specifically, the end face of the filter cartridge facing away from the filter screen axis is an arc surface, and the arc surface of the filter cartridge is in close contact with the inner edge surface of the retaining ring.

[0013] Specifically, the outer edge of the spline rod is provided with a long groove, the length direction of which is parallel to the axial direction of the spline rod. A positioning screw is threaded onto the spline sleeve, with one end of the positioning screw located inside the long groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The fan blades are driven to rotate by the water flow from the main pipeline, and the spline rod drives the brush to clean the surface of the filter screen in real time, effectively preventing impurities from clogging the filter holes. At the same time, the impurities are swept into the filter cartridges on both sides of the filter screen for centralized collection, which significantly reduces the frequency of filter screen maintenance and the risk of clogging.

[0015] 2. Through the floating plate design, the spline sleeve and fan blades can automatically rise and fall with the water level of the main pipeline, ensuring that the fan blades are always located in the upper layer of the water flow. This maintains the stability of water flow-driven cleaning and avoids the negative impact of deep water flow on the pipeline flow velocity.

[0016] 3. The cover plate is removable by connecting screws, allowing the filter screen, spline rod, filter cartridge and other components to be easily removed as a whole, facilitating deep cleaning, impurity removal or component inspection, reducing maintenance time and operational complexity.

[0017] 4. An additional long groove is added to cooperate with the positioning screw to prevent the spline sleeve from accidentally separating from the spline rod when removing the filter screen, ensuring the integrity of the parts and operational safety during disassembly.

[0027] 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.

[0028] Example 1: Refer to Figures 1-7 As shown, an automatic filter cleaning water pipe includes a main pipe 1, with a branch pipe 2 fixedly connected to the upper end of the main pipe 1. The branch pipe 2 is perpendicular to the main pipe 1, and a filter screen 5 is installed inside the upper end of the branch pipe 2. Specifically, a retaining ring 4 is concentrically fixed inside the upper end of the branch pipe 2, blocking the lower end of the filter screen 5. Multiple insert rods 9 are fixed to the upper end of the retaining ring 4, and the insert rods 9 are inserted into the insertion holes of the filter screen 5.

[0029] The filter screen 5 has slots on both sides, and two filter cylinders 8 are fixed at the lower end of the filter screen 5. The upper ends of the two filter cylinders 8 are connected to the two slots respectively. The end face of the filter cylinder 8 away from the axis of the filter screen 5 is an arc surface, and the arc surface of the filter cylinder 8 is in contact with the inner edge of the retaining ring 4.

[0030] By making the arc surface of the filter cartridge 8 fit and contact the inner edge of the retaining ring 4, the stability of the filter screen 5 can be further improved after installation.

[0031] A cover plate 3 is detachably and fixedly connected to the upper end of the branch pipe 2. Specifically, the upper end of the branch pipe 2 is fixedly connected to the upper end of the cover plate 3 by multiple connecting screws. The upper end of the cover plate 3 has multiple elongated holes 15, and a pressure ring 10 is concentrically fixed to the lower end of the cover plate 3, with the lower end of the pressure ring 10 contacting the upper end of the filter screen 5.

[0032] A splined rod 7 is rotatably connected to the center of the filter screen 5. Specifically, the splined rod 7 is rotatably connected to the filter screen 5 via a waterproof bearing 6.

[0033] A spline sleeve 16 is slidably sleeved on the lower outer side of the spline rod 7. Multiple fan blades 17 are evenly distributed and fixed on the lower outer circumference of the spline sleeve 16. A floating plate 18 is concentrically fixed on the lower end of the spline sleeve 16. The lower end of the fan blades 17 is fixedly connected to the upper end of the floating plate 18.

[0034] Spline rod 7 passes through filter screen 5. A rotating rod 13 is fixed on spline rod 7 above filter screen 5. The rotating rod 13 is perpendicular to spline rod 7. Multiple brushes 14 are fixed at the lower end of rotating rod 13. The brushes 14 are in contact with the upper end of filter screen 5.

[0035] A stepped hole 11 is provided in the center of the cover plate 3. The stepped hole 11 is concentric with the spline rod 7. The larger hole of the stepped hole 11 is located at the top, and the smaller hole of the stepped hole 11 is located at the bottom. The upper end of the spline rod 7 is located in the smaller hole of the stepped hole 11. A hexagonal prism 12 is provided in the larger hole of the stepped hole 11. The hexagonal prism 12 is concentrically and fixedly connected to the upper end of the spline rod 7.

[0036] This allows the hexagonal prism 12 to engage with the sleeve of the electric wrench. When the electric wrench is started, the spline rod 7, the rotating rod 13, and the brush 14 can rotate, enabling manual cleaning of the filter screen 5.

[0037] Drainage water enters branch pipe 2 through the elongated hole 15 at the upper end of cover plate 3. The water entering branch pipe 2 is filtered by filter screen 5 and filter cartridge 8 before entering main pipe 1. Filter screen 5 can filter the water entering branch pipe 2.

[0038] The flowing water in the main pipe 1 can impact the fan blade 17. During the rotation of the fan blade 17, the spline rod 7 and the spline sleeve 16 rotate. During the rotation of the spline rod 7, the rotating rod 13 drives the brush 14 to rotate. As the brush 14 rotates with the rotating rod 13, it can brush away the impurities intercepted by the filter screen 5, thus preventing the impurities from clogging the filter holes of the filter screen 5.

[0039] As the impurities intercepted by the filter screen 5 rotate with the brush 14, they can enter the filter cartridge 8 and be collected once they reach the top of the slot. The rotating rod 13 and brush 14 are driven by the power of the water flow in the main pipe 1 to sweep away the impurities intercepted by the filter screen 5, thus achieving automatic cleaning of the filter screen 5. Simultaneously, the filter cartridge 8 can collect impurities at the top of the filter screen 5, reducing the maintenance cycle of the filter screen 5.

[0040] When the water level in the main pipe 1 rises, the float 18 is fixed at the lower end of the spline sleeve 16. Under the buoyancy of the float 18, the height of the float 18, the fan blade 17, and the spline sleeve 16 can change with the water level in the main pipe 1. This ensures that the fan blade 17 is always in the upper layer of the flowing water in the main pipe 1. While ensuring that the flowing water in the main pipe 1 can drive the spline sleeve 16 and the spline rod 7 to rotate through the fan blade 17, it avoids the fan blade 17 and the spline sleeve 16 being always in the deep layer of the flowing water in the main pipe 1, which would affect the flow rate of the flowing water.

[0041] When it is necessary to remove the filter screen 5 for deep cleaning or to remove impurities from the filter cartridge 8, open the cover plate 3 and then pull the filter screen 5 upwards in the branch pipe 2. At this time, the filter screen 5, spline rod 7, spline sleeve 16, fan blade 17, float 18, filter cartridge 8, rotating rod 13, and brush 14 can be removed together from the branch pipe 2, facilitating the inspection and maintenance of the above components.

[0042] Example 2: Based on Example 1, referring to... Figure 8 As shown, a long groove 20 is provided on the outer edge of the spline rod 7. The length direction of the long groove 20 is parallel to the axial direction of the spline rod 7. A positioning screw 19 is threaded onto the spline sleeve 16, and one end of the positioning screw 19 is located in the long groove 20.

[0043] When the filter screen 5 is pulled out from the branch pipe 2, after the positioning screw 19 contacts the lower groove wall of the long groove 20, the spline sleeve 16 can move upward with the spline rod 7, which can prevent the spline sleeve 16 from separating from the spline rod 7.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
