Description

Technical Field

[0001] This invention relates to the field of water conservancy engineering technology, specifically to a water diversion mechanism for water conservancy projects. Background Technology

[0002] Hydraulic engineering primarily studies the fundamental knowledge and skills in engineering hydrology, hydraulic engineering surveying, hydraulic reinforced concrete, hydraulic structures, and engineering drawing. Within the field of hydraulic engineering, it involves engineering planning and design, on-site construction, project budgeting, and maintenance and repair of hydraulic equipment. Examples include the construction of various types of hydraulic structures such as dams, dikes, spillways, sluices, canals, ferries, rafts, and fishways.

[0003] Chinese Patent CN223386599U discloses a water diversion mechanism for a water conservancy project, including a control base, a drainage base, a diversion enhancement component disposed on the surface of the drainage base, and a diversion control component disposed inside the drainage base. When diverting water, the control base is installed near the water source. Multiple pumps are connected to the power output terminals via an external power source. The pumps draw water from the source through an inlet pipe connected to one end. The inlet pipe connects to the pump body via a connector, increasing overall ease of connection. After drawing water through the inlet pipe, the water flow is introduced into a drainage ditch through an outlet pipe connected to one end of the pump body for enhanced diversion. Therefore, the water diversion mechanism exhibits high overall enhanced diversion capacity, facilitating auxiliary diversion and improving overall ease of use.

[0004] However, there are some problems in the use of existing water diversion mechanisms: when the water diversion mechanisms currently on the market are in use, silt and sand are deposited at the filter screen to form a stable sand bed, which is difficult to be moved by the water flow. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a diversion mechanism for water conservancy projects, which solves the problem of sediment deposition at the filter screen forming a stable sand bed.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a water diversion mechanism for a water conservancy project, comprising a drainage base, an outlet pipe and a connecting frame 1 installed at one end of the drainage base, a transmission assembly at the bottom end of the connecting frame 1, multiple connecting rods 2, a transmission shaft 1 and a transmission shaft 2 rotatably connected to the inner wall of the drainage base, gear 1 and gear 2 fixedly connected to the upper and lower ends of the connecting rods 2 respectively, an external gear ring fixedly connected to the outer wall of one end of the transmission shaft 1, gear 1 and a synchronous pulley 1 fixedly connected to the top end of the transmission shaft 2, a synchronous belt 1 meshing with the tooth end of the synchronous pulley 1, multiple connecting frames 2 fixedly connected to the outer wall of the drainage base, a collection box placed at the bottom end of the connecting frame 2, a transmission shaft 3 and a bevel gear 5 rotatably connected to the inner wall of the connecting frame 2, a bevel gear 4 fixedly connected to the other end of the transmission shaft 3, two rotating rods 1 rotatably connected to the top end of the drainage base, multiple worm gears fixedly connected to the outer wall of the rotating rods 1, and a speed reduction assembly provided on the outer wall of the drainage base.

[0007] By adopting the above technical solution: the water flow impacts the transmission component, indirectly driving the two rotating rods to rotate. One of the rotating rods drives the transmission shaft to rotate through the worm, gear one, connecting rod two, gear two, and external gear ring. The other drives the transmission shaft two and transmission shaft three to rotate through the worm, gear one, synchronous pulley one, synchronous belt one, bevel gear five, and bevel gear four. This allows the mud and sand at one point of the transmission shaft to be discharged into the collection box through the transmission shaft one, transmission shaft two, and transmission shaft three, achieving the effect of convenient mud and sand cleaning.

[0008] Preferably, the deceleration assembly includes a fixing frame that is slidably connected to the outer wall of the drainage base. Multiple filter screens (one and two) are installed at the bottom of the fixing frame, and a cleaning assembly is provided at the top of the fixing frame.

[0009] Preferably, the cleaning assembly includes a connecting frame three, which is rotatably connected to the top of the fixed frame. Multiple synchronous pulleys two are fixedly connected to the outer wall of the connecting frame three. The teeth of the synchronous pulleys two are meshed with synchronous belts two. Connecting blocks are rotatably connected to both ends of the connecting frame three. A cleaning frame is rotatably connected to the bottom ends of the two connecting blocks.

[0010] Preferably, the transmission assembly includes a fan blade, which is rotatably connected to the bottom end of the connecting frame one. Both ends of the fan blade are fixedly connected to a bevel gear one. The inner wall of the connecting frame one is rotatably connected to two connecting rods one and a bevel gear three. Both the upper and lower ends of the connecting rods one are fixedly connected to bevel gear two.

[0011] Preferably, one of the bevel gears is meshed with the tooth end of bevel gear one, and the other bevel gear is meshed with the tooth end of bevel gear three. The rotating rod one is fixedly connected to the outer wall of bevel gear three. The fan blade is located at the water outlet of the water outlet pipe. Both the drive shaft one and the drive shaft two are provided with filter holes.

[0012] Preferably, the worm gear is meshed with the tooth end of gear one, and gear two is meshed with the tooth end of the external gear ring.

[0013] Preferably, the first synchronous pulley is fixedly connected to the top of the fifth bevel gear, and the fifth bevel gear is meshed with the tooth end of the fourth bevel gear.

[0014] Preferably, the outer wall of the drainage base is provided with a fixing groove, the fixing frame is slidably connected to the inner wall of the fixing groove, the plurality of filter screens are slidably connected to the outer wall of the drainage base, the outer wall of the drainage base is equipped with a filter frame, and the cleaning frame is slidably connected to the outer wall of the filter frame.

[0015] Preferably, the multiple synchronous belts are fixedly connected to the outer wall of one of the rotating rods.

[0016] Preferably, the bottom end of the cleaning rack is slidably connected to the outer walls of filter screen one and filter screen two.

[0017] Working principle: The fan blade 4 rotates due to the impact of water flow. The fan blade 4 indirectly drives multiple drive shafts 14, 26, and 37 to rotate together through the transmission structure such as bevel gear 16, bevel gear 27, and connecting rod 15. Drive shaft 14 at the bottom of the inner wall of the drainage base 1 transports the mud and sand to the bottom of drive shaft 26. The water in the mud and sand is filtered by drive shaft 14 and drive shaft 26, and the mud and sand are discharged into the collection box 22 through drive shaft 26, drive shaft 317, and connecting frame 23, thus achieving the effect of convenient mud and sand cleaning.

[0018] By fixing multiple filter screens 2402 and 2403 to the bottom of the mounting bracket 2401, and mounting the mounting bracket 2401 on the inner wall of the drainage base 1, the filter screen 2403 contacts the bottom of the inner wall of the drainage base 1, thereby slowing down the water flow and improving the water filtration effect of the filter screen 2403 and the filter bracket.

[0019] During the rotation of the rotating rod 8, one of the rotating rods 8 drives the cleaning frame 2505 to move up and down on the outer wall of the filter screen 2402, the filter screen 2403 and the filter frame through the transmission structure such as the synchronous pulley 2501, the synchronous belt 2502 and the connecting frame 2503, so as to prevent mud and sand from clogging the filter screen.

[0020] This invention provides a diversion mechanism for water conservancy projects. It has the following beneficial effects: This invention uses water flow to drive the fan blades to rotate. The fan blades are then driven by a transmission structure consisting of bevel gear one, bevel gear two, connecting rod one, and bevel gear three. This causes transmission shaft one, transmission shaft two, and transmission shaft three to rotate together, allowing mud and sand to be discharged into the collection box through transmission shaft two, transmission shaft three, and connecting frame two, thus achieving the effect of convenient mud and sand cleaning.

[0021] This invention uses multiple filter screens (first and second) that are alternately installed at the bottom of a fixed frame and located at the bottom of the inner wall of a drainage base. This allows the multiple filter screens to slow down the water flow and achieve the effect of convenient water filtration.

[0022] This invention uses one of the rotating rods to drive the cleaning frame up and down through a transmission structure consisting of a timing pulley, a timing belt, and a connecting frame. This allows the cleaning frame to clean the filter screen, the filter screen, and the outer wall of the filter frame, thus preventing mud and sand from clogging the filter screen.

[0025] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described are only some embodiments of the present invention. Equivalent substitutions and technical improvements made based on the embodiments of the present invention are all within the scope of protection of the present invention.

[0026] like Figures 1-6 This invention provides a water diversion mechanism for a water conservancy project, including a drainage base 1. One end of the drainage base 1 is equipped with a water outlet pipe 2 and a connecting frame 3. A transmission assembly is located at the bottom of the connecting frame 3. Multiple connecting rods 11, a transmission shaft 14, and a transmission shaft 16 are rotatably connected to the inner wall of the drainage base 1. Gears 12 and 13 are fixedly connected to the upper and lower ends of the connecting rods 11, respectively. An external gear ring 15 is fixedly connected to the outer wall of one end of the transmission shaft 14. Gears 12 and a synchronous pulley 20 are fixedly connected to the top end of the transmission shaft 16. A synchronous belt 21 is meshed with the teeth of the synchronous pulley 20. Multiple connecting frames 23 are fixedly connected to the outer wall of the drainage base 1. A collection box 22 is placed at the bottom of the connecting frame 23. A transmission shaft 17 and a bevel gear 19 are rotatably connected to the inner wall of the connecting frame 23. A bevel gear 18 is fixedly connected to the other end of the transmission shaft 17. Two rotating rods are rotatably connected to the top end of the drainage base 1. 8. Multiple worm gears 10 are fixedly connected to the outer wall of the rotating rod 1. A speed reduction assembly 24 is provided on the outer wall of the drainage base 1. The transmission assembly includes a fan blade 4, which is rotatably connected to the bottom end of the connecting frame 3. Both ends of the fan blade 4 are fixedly connected to bevel gears 6. Two connecting rods 5 and bevel gears 9 are rotatably connected to the inner wall of the connecting frame 3. Both the upper and lower ends of the connecting rods 5 are fixedly connected to bevel gears 7, one of which meshes with the teeth of bevel gear 6. At one end, another bevel gear 2 7 is meshed with the tooth end of bevel gear 3 9, rotating rod 1 8 is fixedly connected to the outer wall of bevel gear 3 9, fan blade 4 is located at the water outlet of water outlet pipe 2, transmission shaft 1 14 and transmission shaft 2 16 are both provided with filter holes, worm gear 10 is meshed with the tooth end of gear 1 12, gear 2 13 is meshed with the tooth end of external gear ring 15, synchronous pulley 1 20 is fixedly connected to the top of bevel gear 5 19, bevel gear 5 19 is meshed with the tooth end of bevel gear 4 18.

[0027] Specifically, the water flow impacts the fan blade 4, causing it to rotate. This rotation is achieved by the bevel gear 1 6 at both ends, which in turn drives the bevel gear 2 7, connecting rod 1 5, and bevel gear 3 9. The rotating rod 1 8, via bevel gear 3 9, drives the three worm gears 10 to rotate. The two rotating rods 1 8 mesh with gear 1 12 via the worm gears 10, causing the connecting rod 2 11 and drive shaft 2 16 on the inner walls of both sides of the drainage base 1 to rotate. Simultaneously, the connecting rod 2 11, via gear 2 13 and external gear ring 15, drives the drive shaft 1 14 to rotate. The drive shaft 2 16, via synchronous pulley 1 20, synchronous belt 1 21, bevel gear 5 19, and bevel gear 4 18, drives the drive shaft 3 17 to rotate. This allows the drive shafts 1 14 and 2 16 to filter out the water from the mud and sand, and the drive shafts 1 14, 2 16, and 3 17 to clean the mud and sand inside the drainage base 1, thus facilitating mud and sand removal.

[0028] like Figures 1-3 , Figure 5 and Figure 7 The deceleration assembly 24 includes a fixing frame 2401, which is slidably connected to the outer wall of the drainage base 1. Multiple filter screens 2402 and 2403 are installed at the bottom of the fixing frame 2401. A cleaning assembly 25 is provided at the top of the fixing frame 2401. A fixing groove is provided on the outer wall of the drainage base 1. The fixing frame 2401 is slidably connected to the inner wall of the fixing groove. Multiple filter screens 2403 are slidably connected to the outer wall of the drainage base 1. A filter frame is installed on the outer wall of the drainage base 1. A cleaning frame 2505 is slidably connected to the outer wall of the filter frame.

[0029] Specifically, by contacting the bottom of the inner wall of the drainage base 1 with multiple filter screens 2403 and fixing them to the fixing frame 2401, and fixing multiple filter screens 2402 to the outer wall of the fixing frame 2401 and located above one side of the filter screens 2403, the multiple filter screens 2402 and the filter screens 2403 can limit the water flow speed, thereby facilitating the filtration of sediment in the water.

[0030] like Figure 5 , Figure 7 and Figure 8 The cleaning component 25 includes a connecting frame 2503, which is rotatably connected to the top of the fixed frame 2401. Multiple synchronous pulleys 2501 are fixedly connected to the outer wall of the connecting frame 2503. The teeth of the synchronous pulleys 2501 are meshed with synchronous belts 2502. Connecting blocks 2504 are rotatably connected to both ends of the connecting frame 2503. The bottom ends of the two connecting blocks 2504 are rotatably connected to the cleaning frame 2505. Multiple synchronous belts 2502 are fixedly connected to the outer wall of one of the rotating rods 8. The bottom end of the cleaning frame 2505 is slidably connected to the outer walls of the filter screen 2402 and the filter screen 2403.

[0031] Specifically, by engaging two synchronous pulleys 2501 and synchronous belt 2502, one of the rotating rods 8 at the top of the drainage base 1 drives the connecting frame 2503 to rotate via the synchronous pulleys 2501 and synchronous belt 2502. The connecting frame 2503 then drives the cleaning frame 2505 to move up and down via two connecting blocks 2504, so that the cleaning frame 2505 can clean the filter screen 2402, the filter screen 2403 and the outer wall of the filter frame, preventing mud and sand from clogging the filter screen.
