Description
Technical Field
[0001] This invention relates to the field of drainage equipment technology, specifically to a drainage device for water conservancy construction. 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 are also called water engineering projects. Water is an essential and precious resource for human production and life, but its natural state does not fully meet human needs. Only by constructing water conservancy projects can we control water flow, prevent floods, and regulate and distribute water to meet the needs of people's lives and production for water resources. The purpose of water conservancy project construction is to ensure the utilization and management of water resources, provide functions such as water supply, irrigation, flood control, power generation, and water supply, and at the same time maintain the stability and sustainability of the water environment.
[0003] In the construction of water conservancy projects, drainage devices are one of the core pieces of equipment. Their main function is to promptly drain accumulated water, surface water, or groundwater from the construction area to ensure the smooth progress of construction and the normal operation of subsequent water conservancy facilities. As the power core of the drainage device, the working stability of the water pump directly affects the efficiency and reliability of the entire drainage system. However, the water flow involved in water conservancy projects often contains a large number of impurities, including silt, gravel, branches, weeds, and various suspended particulate matter from the natural environment. If these impurities are not removed in a timely and effective manner, they can easily enter the water pump, causing impeller blockage, wear, or even pump burnout. This not only affects the drainage progress but also increases equipment maintenance costs and downtime, and in severe cases, may delay the entire construction cycle of the water conservancy project.
[0004] Traditional impurity removal methods mainly rely on the grid sleeve at the pipe inlet, which is easily clogged by impurities such as plastic. To address the problems of incomplete impurity removal and easy clogging and damage of water pumps in existing water conservancy construction drainage devices, there is an urgent need for a water conservancy construction drainage device that can integrate impurity removal and power transmission, simplify the structure, improve energy utilization, and use low-friction, high-reliability bearings to ensure stable pump operation, improve drainage efficiency, reduce construction costs, and meet the actual needs of water conservancy construction. Summary of the Invention

[0010] In one possible implementation, the impurity removal assembly further includes a secondary gear sleeved on the outside of the conveying cylinder, the secondary gear rotatingly engaging with the conveying cylinder and meshing with a rack, the secondary gear being fixedly connected to the driving gear via multiple connecting rods arranged in a ring around the center line of the conveying cylinder; it also includes a driven gear, which is located on the outside of the frame and meshes with the secondary gear.
[0011] In one possible implementation, the impurity removal component further includes a flipping bump with an elliptical or elliptical fan-shaped cross-section. The flipping bump is connected to the driven gear pin via a rotating shaft and is connected to the frame via a return spring on the lower end face of the carrier plate.
[0012] In one possible implementation, the water storage tank includes a shell, an inlet connected to a water conveyance channel on the outside of the shell, an outlet connected to a water conveyance pipe on the bottom of the shell, the shell is spherical, a vortex-shaped water guide plate is provided on the inner side of the shell, the angle between the water guide plate and the horizontal plane is 1-10 degrees, and the tank also includes a water storage tank cover.
[0013] In one possible implementation, the hydrocyclone diverter includes a diverter housing, an inlet pipe on the outside of the diverter housing, the diverter housing being inverted conical in shape, a mud outlet at the bottom of the diverter housing, and an outlet pipe at the top of the diverter housing.
[0014] In one possible implementation, the hydraulic turbine includes a water inlet pipe with a diameter that gradually decreases along a vortex, and a rotating wheel surrounded by the water inlet pipe. The water inlet pipe has an outlet near the rotating wheel, and a drain pipe is provided at the lower end of the hydraulic turbine. The rotating wheel is fixed to the drive shaft by a pin, and the drive shaft is coaxial with the hydraulic turbine air compressor.
[0015] In one possible implementation, the bearing includes a pair of coaxial and parallel top covers. Symmetrically arranged on opposite sides of the top covers are a drive ring, a pressure cover, a sealing seat, a stationary ring seat, a push ring, a stationary ring, a moving ring seat, and a bushing, arranged coaxially along the axis.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. Large impurities are intercepted by the baffle plate of the impurity removal component, the impurity is carried by the carrier plate and moves with the conveyor belt, and the flipping protrusion pushes the carrier plate to flip so that the impurities are automatically dumped. The impurities are quickly transported by the screw conveyor, which avoids the impurities from entering the water pump and causing impeller blockage. At the same time, the drive gear meshes with the rack and pinion, which drives the conveyor belt and the screw conveyor to work together. The auxiliary gear and the drive gear cooperate to form a bidirectional drive, so that the power for impurity removal and transportation is provided by a single power source. This simplifies the device structure, reduces equipment downtime due to failure, and achieves efficient impurity removal for drainage in water conservancy construction, thereby reducing the risk of construction delays.
[0017] 2. The rotating wheel of the hydraulic turbine assembly is impacted and rotated by the high-speed water flow. It works coaxially with the hydraulic turbine air compressor to recover the energy of the water flow to drive the air compressor to generate compressed air. The compressed air is then sent in reverse to the impurity removal component to blow away fine impurities. This enhances the impurity removal effect without the need for additional energy and significantly improves energy utilization. At the same time, another part of the gas is sent into the bearing and compressed air is introduced through the air hole to form an air film, realizing non-contact support for the rotating parts and reducing friction loss.

[0022] like Figure 1 The above describes a drainage device for hydraulic construction. In one implementation, such as Figure 1-10 The water conservancy construction drainage device shown includes a water conveyance channel 1, a reservoir 5, a hydraulic vortex diverter 6, a water pump 7, and a hydraulic turbine assembly 8, which are connected in sequence by pipelines. Each component forms a closed water flow channel through the pipelines. A debris removal assembly 2 is provided at the top of the water conveyance channel 1. The debris removal assembly 2 includes a conveyor belt 202 supported by a support frame 201 at the top of the water conveyance channel 1. The support frame 201 provides a stable support foundation for the entire debris removal assembly 2, preventing the assembly from shifting or shaking due to water flow impact. It also includes a debris removal drive motor 3. The output end of the debris removal drive motor 3 is fixedly connected to a screw conveyor 4 by a pin. The hydraulic turbine assembly 8 includes a hydraulic turbine 805 and a hydraulic turbine air compressor 807 arranged coaxially. The hydraulic turbine air compressor 807 is connected to the debris removal assembly 2 through an air supply pipe.
[0023] In this embodiment, water flows in from the inlet of the water conveyance channel 1 and first undergoes preliminary impurity removal by the impurity removal component 2. After the impurity removal drive motor 3 starts, it drives the screw conveyor 4 to rotate via a pin shaft. At the same time, the conveyor belt 202 operates synchronously. Large particles of impurities such as leaves, branches, and plastic bags in the water flow are intercepted on the surface by the conveyor belt 202. As the conveyor belt 202 is transported to the feed end of the screw conveyor 4, the screw conveyor 4 quickly transports these impurities to the collection device outside the water conveyance channel 1 to prevent impurities from accumulating and causing blockages in the water conveyance channel 1. The water flow, after preliminary impurity removal, continues to flow along the water conveyance channel 1 and enters the storage tank. The water in pool 5 is used for buffering and sedimentation, and then flows through the hydrocyclone divider 6 for deep purification. Under the power of the water pump 7, the water is transported to the hydraulic wheel assembly 8. The water flow impacts the hydraulic wheel 805 and drives it to rotate. Since the hydraulic wheel 805 is coaxial with the hydraulic turbine air compressor 807, the rotation of the hydraulic wheel 805 directly drives the hydraulic turbine air compressor 807 to work. The generated compressed air is transported to the impurity removal assembly 2 through the air supply pipe. The compressed air is sprayed out from the end of the air supply pipe to blow away the fine impurities attached to the surface of the conveyor belt 202, ensuring that the interception surface of the conveyor belt 202 remains clean and preventing impurities from sticking together and affecting the impurity removal effect.
[0024] The impurity removal component 2 achieves efficient interception and transport of large particles of impurities, removing impurities that may damage subsequent equipment in advance, protecting precision components such as water pump 7 and hydraulic turbine assembly 8, and extending the overall service life of the equipment. At the same time, the coaxial arrangement of hydraulic turbine assembly 8 and hydraulic turbine air compressor 807 enables the recovery and utilization of water flow energy, eliminating the need to provide additional power for the purging function of impurity removal component 2, and significantly reducing energy consumption. In addition, the purging function of compressed air effectively solves the problem of impurity adhesion, ensuring the long-term stable operation of impurity removal component 2 and improving the impurity removal efficiency and reliability of the device.
[0025] In one possible implementation, the conveyor belt 202 wraps around the screw conveyor 4, and the impurity removal assembly 2 includes a driven wheel 203 wrapped by the conveyor belt 202, and also includes a set of parallel frames 204. The opposing surfaces of the two frames 204 form the running track of the conveyor belt 202, ensuring that the conveyor belt 202 moves stably within the range defined by the frames 204. The inner surface of the frames 204 is provided with a rack 206.
[0026] In one possible implementation, the conveyor belt 202 is arranged between opposite faces of the frame 204. A barrier plate 205 is provided on the outer side of the conveyor belt 202. The barrier plate 205 is arranged along the width direction of the conveyor belt 202 and evenly distributed along the length direction of the conveyor belt 202. The barrier plate 205 is perpendicularly fixed to the outer surface of the conveyor belt 202. The conveyor belt 202 includes multiple load plates 208. The load plates 208 are rotatably engaged with the frame 204 through a rotating shaft. The load plates 208 are rectangular plate structures. Multiple load plates 208 are arranged sequentially along the length direction of the conveyor belt 202. A small gap is left between adjacent load plates 208 to avoid mutual interference during movement.
[0027] In this embodiment, when water flows through the conveyor belt 202, impurities in the water are blocked on the outer side of the conveyor belt 202 by the barrier plate 205. Then, as the carrying plate 208 moves synchronously under the drive of the conveyor belt 202, the impurities are lifted to the screw conveyor 4. The impurities are then poured into the screw conveyor 4, realizing the automatic transfer of impurities. The barrier plate 205 enhances the impurity interception capability and improves the impurity removal efficiency. The sequential arrangement of multiple carrying plates 208 enables the impurity conveying to form a continuous operation without manual intervention, improving the automation level and working efficiency of the device and reducing the labor intensity of operators. At the same time, the rotational cooperation structure between the carrying plate 208 and the frame 204 is simple, reliable in operation, and low in maintenance cost, ensuring the long-term stable operation of the device.
[0028] In one possible embodiment, the screw conveyor 4 includes a conveying cylinder 402, which has a cylindrical structure and a feed inlet partially opened below the impurity removal component 2. It also includes a rotating shaft 401 arranged coaxially with the conveying cylinder 402. Spiral blades 403 are provided on the outer side of the rotating shaft 401, and the outer diameter of the spiral blades 403 is adapted to the inner diameter of the conveying cylinder 402 to ensure that impurities can be pushed forward by the spiral blades 403 and will not accumulate in the gaps. The rotating shaft 401 is connected to a motor via a reducer 301. The input end of the reducer 301 is fixedly connected to the output shaft of the motor, and the output end is fixedly connected to one end of the rotating shaft 401. The speed reducer 301 can adjust the rotation speed of the rotating shaft 401. A bearing 9 is provided on the outside of the rotating shaft 401. The bearing 9 is sleeved on the rotating shaft 401 and located between the speed reducer 301 and the conveying cylinder 402. A drive gear 10 is provided on the outside of the rotating shaft 401 near the bearing 9 via a pin. The drive gear 10 meshes with the rack 206. A sealing baffle 207 is provided on the outside of the rotating shaft 401 at the end of the drive gear 10 away from the bearing 9. The sealing baffle 207 is sleeved on the outside of the rotating shaft 401. One side of the sealing baffle 207 is spaced 3-5mm away from the drive gear 10, and a sealing gasket is provided on the outside of the sealing baffle 207 to prevent water from contacting the drive gear 10.
[0029] In this embodiment, after the motor of the impurity removal drive motor 3 is started, its output power is transmitted to the rotating shaft 401 through the reducer 301. The reducer 301 adjusts the output speed according to the actual impurity removal requirements, so that the rotating shaft 401 rotates at a suitable speed. The rotating shaft 401 drives the spiral blades 403 to rotate inside the conveying cylinder 402. The impurities conveyed from the conveyor belt 202 enter the feed end of the conveying cylinder 402. Under the push of the spiral blades 403, they move along the length of the conveying cylinder 402 towards the discharge end, and are finally discharged from the discharge end to the collection device.
[0030] As the rotating shaft 401 rotates, the drive gear 10 rotates synchronously with it. Since the drive gear 10 meshes with the rack 206 on the inner side of the frame 204, the rotation of the drive gear 10 drives the frame 204 to move relative to each other, thereby driving the conveyor belt 202 to operate synchronously. This realizes the linkage control between the screw conveyor 4 and the conveyor belt 202, ensuring that the speeds of the two are matched and the impurity conveying is smooth.
[0031] The sealing baffle 207 forms a sealing barrier between the drive gear 10 and the conveyor cylinder 402, preventing impurities, powder, or moisture in the conveyor cylinder 402 from entering the bearing 9 and the reducer 301, thus avoiding wear or corrosion of the components. The meshing of the drive gear 10 and the rack 206 enables the synchronous operation of the conveyor belt 202 and the screw conveyor 4, reducing control links and lowering equipment complexity and failure rate. The sealing and protective function of the sealing baffle 207 effectively protects key transmission components such as the bearing 9 and the reducer 301, extending their service life, reducing maintenance costs, and improving the operational reliability of the device.
[0032] In one possible implementation, the impurity removal assembly 2 further includes a secondary gear 209 sleeved on the outside of the conveying cylinder 402. The secondary gear 209 is sleeved on the outside of the conveying cylinder 402, and its central hole diameter is larger than the outer diameter of the conveying cylinder 402, so that the secondary gear 209 can rotate freely relative to the conveying cylinder 402. The secondary gear 209 rotates with the conveying cylinder 402 and meshes with the rack 206. The secondary gear 209 is fixedly connected to the driving gear 10 through multiple connecting rods 213. The connecting rods 213 are cylindrical rod-shaped structures and there are at least 12 of them. The connecting rods 213 are arranged in a ring around the center line of the conveying cylinder 402. It also includes a driven gear 210, which is located on the outside of the frame 204 and meshes with the secondary gear 209.
[0033] In this embodiment, when the rotating shaft 401 drives the driving gear 10 to rotate, the driving gear 10 drives the secondary gear 209 to rotate synchronously through at least 12 annularly arranged connecting rods 213. Since the secondary gear 209 meshes with the rack 206, its rotation direction is consistent with that of the driving gear 10, forming a bidirectional drive for the rack 206. This ensures that the driving force on the rack 206 is balanced, avoiding the problem of uneven force and increased wear on the rack 206 caused by unilateral drive. It also enhances the stability of the conveyor belt 202 movement and prevents it from deviating or shaking during operation. The annular and uniform arrangement of the connecting rods 213 ensures balanced power transmission between the driving gear 10 and the secondary gear 209, avoiding the breakage or deformation of the connecting rods 213 caused by local stress concentration, and improving the reliability and service life of the connection structure. When the secondary gear 209 rotates, it transmits power to the driven gear 210, causing the driven gear 210 to rotate synchronously, providing a power source for the subsequent operation of the flipping protrusion 212. The dual-gear linkage between the auxiliary gear 209 and the driving gear 10 optimizes the distribution of driving force, reduces the wear of the rack 206 and gears, and extends the service life of the transmission components. The annular arrangement of the connecting rod 213 enhances the stability of the connection structure and the balance of power transmission, improving the mechanical strength of the device. The driven gear 210 provides a stable power source for the subsequent impurity overturning and dumping function, further improving the smoothness and accuracy of the conveyor belt 202 movement, ensuring continuous and efficient impurity interception and transportation.
[0034] In one possible implementation, the impurity removal component 2 further includes a flipping protrusion 212. The flipping protrusion 212 has an elliptical or elliptical fan-shaped cross-section, which allows the flipping protrusion 212 to generate a gradual thrust when rotating, avoiding impact on the carrying plate 208. The flipping protrusion 212 is connected to the driven gear 210 pin through a rotating shaft. The rotating shaft passes through the center of the flipping protrusion 212 and is fixedly connected to the driven gear 210, ensuring that the flipping protrusion 212 and the driven gear 210 rotate synchronously. The lower end face of the carrying plate 208 is connected to the frame 204 through a return spring 211. One end of the return spring 211 is fixedly connected to the lower end face of the carrying plate 208, and the other end is fixedly connected to the inner side wall of the frame 204. When the return spring 211 is in its natural state, the carrying plate 208 remains in a horizontal state.
[0035] In this embodiment, the driven gear 210 rotates under the drive of the secondary gear 209, which drives the flipping protrusion 212 to rotate synchronously. When the carrying plate 208 moves to the flipping area, the elliptical or elliptical fan-shaped cross section of the flipping protrusion 212 gradually contacts the lower end surface of the carrying plate 208. As the flipping protrusion 212 continues to rotate, its thrust on the carrying plate 208 gradually increases, pushing the carrying plate 208 to flip upward around the rotation axis. The impurities carried on the carrying plate 208 slide off the surface of the carrying plate 208 into the screw conveyor 4 under the combined action of the flipping force and gravity. When the flipping protrusion 212 rotates to disengage from the carrier plate 208, the return spring 211 on the lower end face of the carrier plate 208, under its own elastic restoring force, pulls the carrier plate 208 downward to rotate back to a horizontal state, waiting for the next impurity carrying and flipping operation. The return spring 211 realizes the automatic reset of the carrier plate 208 without the need for additional power drive, simplifying the device structure and reducing energy consumption. The automatic flipping of the carrier plate 208 is realized through the linkage design of the flipping protrusion 212 and the driven gear 210, ensuring that impurities can be quickly and thoroughly transferred to the screw conveyor 4, avoiding impurities being thrown into the water conveying channel 1 by the carrier plate 208. The elliptical structure of the flipping protrusion 212 reduces mechanical impact, improves the stability of the device operation, is simple and reliable, has low maintenance costs, is suitable for long-term high-intensity impurity removal work, and ensures that the device can operate stably under complex working conditions.
[0036] In one possible implementation, the water storage tank 5 includes a shell 502, with an inlet on the outside of the shell 502 communicating with a water conveyance channel, and an outlet 504 at the bottom of the shell 502 communicating with a water conveyance pipe. The shell 502 is spherical, and a vortex-shaped water guide plate 503 is provided on the inner side of the shell 502. The angle between the water guide plate 503 and the horizontal plane is 1-10 degrees, which can guide the water flow to generate vortex motion without excessively hindering the water flow speed. It also includes a water storage tank cover 501, which covers the top opening of the shell 502 and is sealed to the shell 502 to prevent external dust, debris and other pollutants from entering the interior of the shell 502.
[0037] In this embodiment, the water, after being initially impurity removed by the impurity removal component 2, enters the interior of the shell 502 of the water storage tank 5 through the inlet. The water first comes into contact with the vortex-shaped water guide plate 503 on the inner side of the shell 502. Under the guidance of the water guide plate 503, the water flows along the vortex path inside the shell 502. Since the water guide plate 503 is at an angle of 1-10 degrees to the horizontal plane, the water generates vortex motion during the flow, thereby accelerating the water flow speed. The sealing effect of the water storage tank cover 501 prevents external pollutants from entering the water flow and prevents secondary pollution of the water quality. After the water guide plate 503 accelerates the flow speed, the water is guided through the water pipe into the subsequent hydraulic vortex diverter 6, providing the necessary flow velocity conditions for the hydraulic vortex diverter 6 to form high-speed vortex motion.
[0038] In one possible implementation, the hydrocyclone divider 6 includes a divider housing 601, with an inlet pipe 602 on the outside of the divider housing 601. The inlet pipe 602 is tangentially connected to the side wall of the divider housing 601, so that the water flow entering the divider housing 601 has an initial tangential velocity and can quickly form a vortex motion. The divider housing 601 is inverted cone-shaped, with a mud outlet 603 at the bottom end and a water outlet pipe 604 at the top end.
[0039] In this embodiment, the water flowing out of the water storage tank 5 enters the interior of the distributor housing 601 through the water inlet pipe 602. Since the water inlet pipe 602 is tangentially connected to the distributor housing 601, the water flows along the tangential direction of the housing when it enters, and quickly forms a high-speed vortex motion.
[0040] During the vortex motion, fine silt, suspended particles and other impurities in the water flow gather towards the inner wall of the distributor housing 601 under the action of centrifugal force. At the same time, the distributor housing 601 is inverted cone shape, and its inner diameter gradually decreases from top to bottom. The vortex speed of the water flow gradually increases from top to bottom, and the centrifugal force also increases accordingly, further pushing the impurities towards the inner wall.
[0041] Impurities settle downwards along the inner wall of the distributor housing 601 and eventually accumulate at the bottom of the housing. By periodically opening the valve of the mud outlet 603, the impurities can be discharged, achieving centralized treatment of the impurities. The clean water after centrifugal separation forms an upward flow in the center of the vortex, flows upwards and flows out through the water outlet pipe 604 at the top, and enters the water pump 7 for pressurized transportation.
[0042] The inverted conical splitter housing 601 and the tangentially arranged inlet pipe 602 jointly enhance the vortex motion of the water flow, improve the centrifugal separation efficiency, effectively remove fine silt and suspended particles from the water flow, and significantly improve water quality. The outlet pipe 604, located at the top, ensures the smooth flow of clean water, achieving efficient separation of silt and clean water. The deep purification effect of the hydrocyclone splitter 6 further reduces the pollution risk of the water supply system, provides clean water flow conditions for the stable operation of the subsequent water pump 7, reduces equipment wear, and extends the service life of the equipment.
[0043] In one possible implementation, the hydraulic turbine 805 includes a water inlet pipe 801 with a diameter that gradually decreases along a vortex, and a rotating wheel 803 surrounded by the water inlet pipe 801. The water inlet pipe 801 has an outlet near the rotating wheel 803, and a drain pipe 802 is provided at the lower end of the hydraulic turbine. The rotating wheel 803 is fixed to the drive shaft by a pin, and the drive shaft is coaxial with the hydraulic turbine air compressor 807.
[0044] In this embodiment, the purified water after passing through the hydrocyclone divider 6 enters the water pump 7. The water pump 7 pressurizes the water flow, increasing its pressure and speed. The pressurized water flow is then transported through a pipeline to the water inlet pipe 801 of the hydraulic turbine assembly 8. As the diameter of the water inlet pipe 801 gradually decreases along a vortex shape, the kinetic energy of the water flow gradually increases and its speed continuously increases as it flows within the water inlet pipe 801. The water is then ejected at high speed from the outlet near the rotating wheel 803 of the water inlet pipe 801, uniformly impacting the blades of the rotating wheel 803 and driving the rotating wheel 803 to rotate at high speed. The rotating wheel 803 drives the active rotating shaft to rotate synchronously via a pin. Since the active rotating shaft is coaxial with the hydraulic turbine air compressor 807, the rotation of the active rotating shaft directly drives the hydraulic turbine air compressor 807 to work. After the hydraulic turbine air compressor 807 compresses the air, it is transported to the impurity removal assembly 2 through an air delivery pipe, providing power for the impurity purging function of the impurity removal assembly 2.
[0045] The compressed air generated by the hydraulic turbine air compressor 807 provides auxiliary power for the impurity removal component 2, improving the impurity removal effect and increasing energy utilization efficiency. At the same time, the coordinated operation of the high-speed rotating wheel 803 and the hydraulic turbine air compressor 807 ensures the stable operation of the device and provides a guarantee for the safety and reliability of the water supply system.
[0046] In one possible implementation, the bearing 9 includes a pair of coaxial and parallel top covers 903. Symmetrically arranged on opposite sides of the top covers 903 are a drive ring 914, a pressure cover 913, a sealing seat 910, a stationary ring seat 909, a push ring 908, a stationary ring 907, a moving ring seat 906, and a bushing 904, arranged sequentially along the axis and coaxially. A sealing O-ring 905 is provided between the moving ring seat 906 and the bushing 904. A flow guide sleeve 912 is provided between the pressure cover 913 and the sealing seat 910. A sealing gasket 911 is provided between the 12 and the pressure cap 913 and the sealing seat 910 respectively. A sealing sleeve 915 is provided between the opposite surfaces of the sealing seat 910. The sealing sleeve 915 is clearance-fitted with the bushing 904. An air hole communicating between the inside and outside is provided on the outer side of the bushing 904. The cavity between the guide sleeve 912 and the bushing 904 forms an air inlet and outlet cavity. The cavity between the bosses at both ends of the bushing 904 and the sealing sleeve 915 forms a buffer chamber. An air inlet pipe 901 and an air outlet pipe 902 communicating between the inside and outside are provided on the sealing seat 910.
[0047] In this embodiment, the air holes on the outer side of the bushing 904 are concentrated on one side of the bearing 9 and are marked on the outer surface. During installation, the side with concentrated air holes is at the lower position. When the bearing 9 is running, the gas from the external air source enters through the air inlet pipe 901 on the sealing seat 910. It first flows into the air inlet / outlet chamber between the guide sleeve 912 and the bushing 904, and then enters the interior of the bearing 9 through the air holes on the outer side of the bushing 904. The compressed air flowing out of the air holes enters the tiny gap between the bushing 904 and the rotating shaft 401. In this gap, the airflow forms a stable air film. This air film separates the rotating shaft 401 from the stationary bushing 904, thereby achieving non-contact support and reducing frictional losses between components. When the airflow passes through the buffer chamber, the buffer chamber regulates the flow rate and pressure of the airflow to avoid excessive airflow impact that could cause the air film to become unstable. After completing the support function, the gas flows back to the air inlet / outlet chamber through the air holes of the bushing 904, and finally exits the bearing 9 through the air outlet pipe 902, forming a complete airflow cycle.
[0048] The working process of the hydraulic construction drainage device provided in this embodiment is as follows: The general working principle is as follows: Water first flows in from the water conveyance channel 1. At the same time, the impurity removal drive motor 3 starts and drives the screw conveyor 4 to rotate through the pin shaft. Simultaneously, the drive gear 10 rotates with the rotating shaft 401 and meshes with the rack 206 on the inner side of the frame 204, driving the conveyor belt 202 to operate synchronously. The barrier plate 205 of the carrying plate 208 intercepts large particles of impurities in the water flow. The carrying plate 208 carries the impurities and moves with the conveyor belt 202. When the carrying plate 208 moves to the flipping area, the driven gear 210 drives the flipping protrusion 212 to rotate under the drive of the auxiliary gear 209, pushing the carrying plate 208 to flip and dump the impurities onto the screw conveyor 4. The screw conveyor 4 transports the impurities to the collection device, completing the initial impurity removal.
[0049] The water that has undergone preliminary impurity removal enters the water storage tank 5 and generates vortex motion under the guidance of the vortex-shaped guide plate 503, which realizes efficient acceleration of the water flow and avoids the attenuation of the water flow velocity in the water storage tank. This provides a suitable flow velocity basis for the subsequent operation of the hydraulic vortex diverter 6. The water storage tank cover 501 prevents secondary pollution. The accelerated water flow flows out from the outlet 504 and enters the hydraulic vortex diverter 6.
[0050] Water flows through the inlet pipe 602 into the inverted cone-shaped distributor housing 601, forming a high-speed vortex motion along the tangential direction. Fine silt and suspended particles gather and settle towards the inner wall under the action of centrifugal force and are discharged from the sludge outlet 603. The purified water flows out from the top outlet pipe 604 and enters the water pump 7.
[0051] After pressurizing the clean water, the water pump 7 delivers it to the water inlet pipe 801 of the hydraulic turbine assembly 8. The gradually changing diameter of the water inlet pipe 801 accelerates the water flow, which is then ejected at high speed from the outlet to impact the rotating wheel 803, causing the rotating wheel 803 to rotate. The rotating wheel 803 drives the coaxial hydraulic turbine air compressor 807 through the active rotating shaft. The generated compressed air is delivered to the impurity removal assembly 2 through the air supply pipe to blow away the fine impurities on the surface of the conveyor belt 202, assisting in impurity removal. The water flow after impacting the rotating wheel 803 is discharged from the drain pipe 802. At the same time, some gas is introduced into the compressed air through the air holes on the outer side of the bushing 904, forming a stable air film between the rotating shaft 401 and the bushing 904, achieving non-contact support. Meanwhile, the concentrated side of the air holes is located at a low position, which can minimize the air pressure requirements and ensure low friction and stable rotation of the rotating shaft 401.
[0052] Meanwhile, the entire device adopts a modular design, with all functional components being independent modules that are assembled through detachable connectors. This facilitates individual transportation, on-site disassembly and assembly, and flexible layout according to terrain, significantly improving the device's transportation convenience, maintenance ease, and terrain adaptability.
