Description

Technical Field

[0001] This utility model relates to the field of water conservancy pipeline component technology, specifically a water conservancy pipeline designed to prevent silt blockage. Background Technology

[0002] As the core carrier of water resource allocation, water conservancy pipelines are widely used in fields such as farmland irrigation, urban water supply and flood control and drainage. In the process of transporting water with high sediment content, the deposition of silt on the inner wall of the pipeline has been a common problem that has long plagued the industry. According to statistics, the average annual dredging frequency of pipelines in irrigation areas in northern my country is 4-6 times, and each dredging takes 8-12 hours, resulting in a loss of about 20% of water conveyance efficiency.

[0003] Traditional water conservancy pipelines mostly adopt straight or right-angle bend structures. Their inner walls are not smooth enough and lack flow guidance design, which makes it easy for silt particles to accumulate at bends and diameter changes when the water flow velocity decreases. Existing anti-clogging measures mainly rely on manual periodic cleaning or mechanical sludge scraping devices. However, the former is labor-intensive and poses safety hazards, while the latter is prone to secondary blockage due to its complex structure, making it difficult to meet the intelligent and efficient operation requirements of modern water conservancy projects. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a water conservancy pipeline designed to prevent silt blockage. Through the coordinated design of an annular anti-blockage connecting cavity and a flat bottom groove, combined with a bidirectional stirring paddle and a three-dimensional oblique spray nozzle, a three-dimensional anti-blockage system is formed, which effectively prevents silt blockage. The cleaning process integrates high-temperature pre-rinsing, chemical dissolution, and clean water finishing modes, effectively achieving cleaning-based anti-blockage and achieving efficient anti-blockage and long-term operation and maintenance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a water conservancy pipeline for preventing silt blockage, comprising an anti-blockage frame box, a first water conservancy pipe, and a second water conservancy pipe. An anti-blockage connection cavity is provided around the inner wall of the anti-blockage frame box. A flat bottom groove is provided at the bottom of the anti-blockage connection cavity. A first setting groove is provided near the left side of the inner wall of the anti-blockage connection cavity. A second setting groove is provided near the right side of the inner wall of the anti-blockage connection cavity. A third setting groove is provided at the top of the inner wall of the anti-blockage connection cavity. A booster pump box is provided at the middle of the top outer wall of the anti-blockage frame box and connected by bolts. A diversion supply pipe is provided on the inner wall of the third setting groove. The top of the diversion supply pipe is connected to the booster pump box via a flange.

[0006] Preferably, a first oblique nozzle is provided on the left side of the bottom of the diversion supply pipe, a second oblique nozzle is provided at the middle of the bottom of the diversion supply pipe, and a third oblique nozzle is provided on the right side of the bottom of the diversion supply pipe.

[0007] Preferably, a drive motor is connected to the bottom of the left outer wall of the anti-blocking frame box via a bracket, a rotating shaft is provided on the inner wall of the setting groove, a left-side agitator is keyed to the right end of the rotating shaft, and the left end of the rotating shaft is connected to the drive motor via a coupling.

[0008] Preferably, a second drive motor is connected to the outer right side of the anti-blocking frame box near the bottom via a bracket. A second rotating shaft is provided on the inner wall of the second setting groove. A right-side agitator is keyed to the left end of the second rotating shaft, and the right end of the second rotating shaft is connected to the second drive motor via a coupling.

[0009] Preferably, a cleaning water heater is provided at the left end of the top outer wall of the anti-clogging frame box, and a dissolving cleaning solution mixing tank is provided at the right end of the top outer wall of the anti-clogging frame box. The right end of the cleaning water heater and the left end of the dissolving cleaning solution mixing tank are both connected to a booster pump box through pipelines.

[0010] Preferably, a first water pipe is connected around the front outer wall of the anti-blocking connection cavity, and a second water pipe is connected around the rear outer wall of the anti-blocking connection cavity. A reinforcing ring frame is provided at the rear end of the first water pipe and the front end of the second water pipe. The reinforcing ring frames are all connected to the anti-blocking frame box by bolts.

[0011] This utility model provides a water conservancy pipeline that prevents silt blockage. It has the following beneficial effects:

[0012] This type of anti-siltation water conservancy pipeline utilizes multiple mechanical anti-clogging structures to improve pipeline operation efficiency. Through a unique mechanical structure design, it achieves three-dimensional control of silt deposition. The anti-clogging connection cavity inside the anti-clogging frame adopts a ring structure design, combined with a flat bottom groove, effectively avoiding the silt retention problem caused by the right-angle structure of traditional pipelines. The slope design of the flat bottom groove allows the silt particles carried by the water flow to naturally flow to both sides under gravity, reducing the probability of deposition. Left and right agitators installed in groove one and groove two respectively, driven by drive motor one and drive motor two, form a bidirectional rotating agitation flow field. The symmetrical agitation structure not only breaks up existing silt clumps, but also... The spiral water flow can push the sediment towards the pipe outlet, significantly reducing the risk of siltation. The diversion supply pipe in the third channel is equipped with three angled nozzles: angled nozzle one, angled nozzle two, and angled nozzle three. The nozzles are distributed at an inclined angle, which can generate a directional high-pressure water jet. When the water flow velocity in the pipe decreases, the booster pump box starts and distributes high-pressure water to each nozzle through the diversion supply pipe. The water flow direction of the left nozzle is at a counterclockwise angle to the pipe axis, while the right nozzle is at a clockwise angle. The middle nozzle sprays vertically downward. This three-dimensional flushing mode can form a spiral upward water flow in the anti-clogging connection cavity, which not only flushes the mud and scale attached to the inner wall of the pipe, but also suspends the silt deposited at the bottom and carries it out of the pipe through the water flow, thus achieving anti-clogging.

[0013] This type of anti-sludge-clogging water pipe creatively combines thermal cleaning with chemical cleaning. It constructs a cleaning mode through a cleaning water heater and a dissolving cleaning solution mixing tank. The cleaning water heater can raise the water temperature, and the high-temperature water flow can effectively soften stubborn scale and biological slime. The dissolving cleaning solution mixing tank can store acidic or alkaline cleaning solutions, which, after mixing with hot water, form a highly efficient descaling solution. First, high-temperature hot water is injected for pre-rinsing, then chemical cleaning solution is injected for circulation and dissolution, and finally, it is rinsed with clean water. This composite cleaning process significantly improves the anti-sludge and anti-clogging effect compared to traditional mechanical cleaning. Attached Figure Description

[0020] Please see Figure 1-4This utility model provides a technical solution: a water conservancy pipeline for preventing silt blockage, including an anti-blockage frame box 1, a first water conservancy pipe 21, and a second water conservancy pipe 22. An anti-blockage connecting cavity 2 is provided around the inner wall of the anti-blockage frame box 1, and a flat bottom groove 3 is provided at the bottom of the anti-blockage connecting cavity 2. Through multiple innovative structures, efficient anti-blockage and cleaning-based anti-blockage operations are achieved synergistically. The anti-blockage connecting cavity 2 and the flat bottom groove 3 inside the anti-blockage frame box 1 form a unique silt interception design. When water flows through, the flat bottom groove 3 can effectively... To control the flow rate and prevent silt particles from forming blockages, a first groove 4 is provided on the inner wall of the anti-blocking connecting cavity 2 near the left side, a second groove 5 is provided on the inner wall of the anti-blocking connecting cavity 2 near the right side, and a third groove 6 is provided at the top of the inner wall of the anti-blocking connecting cavity 2. The first groove 4, the second groove 5, and the third groove 6 on the inner wall of the anti-blocking connecting cavity 2 respectively accommodate the drive motor, the rotating shaft, and the agitator. Through the synchronous rotation of the left agitator 14 and the right agitator 17, a spiral disturbance can be generated in the water flow, breaking up the silt. The stability of the sediment is ensured, allowing it to remain suspended and be discharged with the water flow. A booster pump box 7 is installed at the middle of the top outer wall of the anti-clogging frame box 1 and connected by bolts. A diversion supply pipe 8 is installed on the inner wall of the three-stage trough 6. The top of the diversion supply pipe 8 is connected to the booster pump box 7 via a flange. An oblique jet nozzle 1 9 is located on the left side of the bottom of the diversion supply pipe 8, an oblique jet nozzle 2 10 is located at the middle of the bottom of the diversion supply pipe 8, and an oblique jet nozzle 3 11 is located on the right side of the bottom of the diversion supply pipe 8. The diversion supply... The combination design of pipe 8 and angled nozzles enables directional flushing. The booster pump box 7 mixes the high-temperature water heated by the cleaning water heater 18 with the chemical solution in the dissolving cleaning solution box 19. The mixture is then sprayed at different angles to the bottom of the anti-clogging connection cavity 2 through the angled nozzles 19, 10, and 11 at the bottom of the pipe 8. The high-temperature water reduces the viscosity of the sludge, while the chemical solution further decomposes organic matter. The combination of the two significantly improves the cleaning efficiency, ensuring that even the sludge deposited in corners can be effectively removed.

[0021] A drive motor 12 is connected to the bottom of the left outer wall of the anti-clogging box 1 via a bracket. A rotating shaft 13 is installed on the inner wall of the setting slot 4. A left-position agitator 14 is keyed to the right end of the rotating shaft 13. The left end of the rotating shaft 13 is connected to the drive motor 12 via a coupling. A drive motor 15 is connected to the bottom of the right outer wall of the anti-clogging box 1 via a bracket. A rotating shaft 16 is installed on the inner wall of the setting slot 5. A right-position agitator 17 is keyed to the left end of the rotating shaft 16. The right end of the rotating shaft 16 is connected to the drive motor 15 via a coupling. The left-position agitator 14 and the right-position agitator 17 installed in the setting slot 4 and setting slot 5 respectively form a bidirectional rotating agitation flow field under the drive of the drive motor 12 and the drive motor 15. The symmetrical agitation structure can not only break up the formed silt clumps, but also push the silt towards the pipe outlet through the spiral water flow, significantly reducing the risk of siltation.

[0022] A cleaning water heater 18 is installed on the left end of the top outer wall of the anti-clogging frame box 1, and a dissolving cleaning solution mixing tank 19 is installed on the right end of the top outer wall of the anti-clogging frame box 1. The right end of the cleaning water heater 18 and the left end of the dissolving cleaning solution mixing tank 19 are both connected to the booster pump box 7 through pipelines. The cleaning water heater 18 can raise the water temperature, and the high-temperature water flow can effectively soften stubborn scale and biological slime. The dissolving cleaning solution mixing tank 19 can store acidic or alkaline cleaning solutions, which, after being mixed with hot water, form a highly efficient descaling solution.

[0023] A hydraulic pipe 21 is connected around the front outer wall of the anti-blocking connection cavity 2, and a hydraulic pipe 22 is connected around the rear outer wall of the anti-blocking connection cavity 2. A reinforcing ring frame 20 is provided at the rear end of the hydraulic pipe 21 and the front end of the hydraulic pipe 22. The reinforcing ring frame 20 is connected to the anti-blocking frame box 1 by bolts. The anti-blocking frame box 1 is connected to the hydraulic pipe 21 and the hydraulic pipe 22 by the reinforcing ring frame 20 and bolts, which not only improves the sealing performance and compressive strength of the overall structure, but also facilitates quick disassembly and assembly.

[0024] Working Principle: Through multiple innovative structures, efficient anti-clogging and cleaning-based anti-clogging operations are achieved synergistically. The anti-clogging connecting cavity 2 and the flat bottom trough 3 inside the anti-clogging frame 1 form a unique sludge interception design. When water flows through, the flat bottom trough 3 effectively controls the flow rate, preventing sludge particles from forming blockages. The grooves 4, 5, and 6 on the inner wall of the anti-clogging connecting cavity 2 respectively accommodate the drive motor, rotating shaft, and agitator. The synchronous rotation of the left agitator 14 and the right agitator 17 generates a spiral disturbance in the water flow, breaking the stability of sludge deposition, keeping it suspended, and allowing it to be discharged with the water flow. The combination design of the diversion supply pipe 8 and the angled spray nozzle achieves directional flushing. The booster pump box 7 supplies cleaning water to the heater 18. After the heated high-temperature water and the chemical solution in the dissolving cleaning solution are mixed in the tank 19, they are sprayed at different angles to the bottom of the anti-clogging connection cavity 2 through the angled spray nozzles 19, 10, and 11 at the bottom of the distribution supply pipe 8. The high-temperature water can reduce the viscosity of the sludge, while the chemical solution further decomposes organic matter. The combination of the two significantly improves the cleaning efficiency, ensuring that the sludge deposited in the corners can also be effectively removed. The anti-clogging frame box 1 is connected to the water pipe 21 and 22 by a reinforced ring frame 20 and bolts, which not only improves the sealing and compressive strength of the overall structure, but also facilitates quick disassembly and assembly. The independent configuration of the cleaning water heater 18 and the dissolving cleaning solution mixing tank 19 allows for flexible adjustment of the cleaning plan according to the degree of water pollution.
