Description

Technical Field

[0001] This invention relates to the field of hydropower technology, and specifically discloses an integrated device for generating and storing residual pressure in a water purification system. Background Technology

[0002] Traditional reverse osmosis (RO) water purification systems, as an important part of the water treatment field, are a membrane separation technology developed in the 1960s. The principle is that raw water passes through a reverse osmosis membrane under high pressure, and the solvent in the water diffuses from high concentration to low concentration, thereby achieving separation, purification, and concentration. Because it is the opposite of the osmosis direction in nature, it is called reverse osmosis. With the improvement of membrane materials, its application fields have expanded to the deep treatment of urban sewage, heavy metal recovery, and oily wastewater purification, with a treatment capacity of millions of tons per day. This system relies on the powerful driving force of high-pressure pumps to ensure the smooth operation of the water purification process. However, in this process, the residual pressure carried by the discharged concentrated water is often wasted and not effectively utilized.

[0003] For example, patent CN221423336U, published on July 26, 2024, discloses a residual pressure power generation device for an industrial water circulation system, belonging to the field of residual pressure power generation technology. It includes a water storage tank, a connecting pipe at the bottom right end of the tank, and a diversion pipe at the bottom of the tank. The other ends of the connecting pipe and the diversion pipe are connected to the same water turbine. A generator is mounted on the right end of the water turbine via a rotating shaft. A water outlet is located at the front end of the water turbine. A first solenoid valve is located at the bottom of the connecting pipe, and a second solenoid valve is located at the right end of the diversion pipe. The diversion pipe is inclined downwards from left to right, and the connecting pipe is L-shaped. The connecting pipe and the diversion pipe are configured in conjunction. The water turbine and the generator are located on the same horizontal plane. A water inlet is located at the top of the water storage tank. This device not only enables water diversion and regulation, ensuring efficient utilization of water pressure, but also improves the performance of the water turbine and increases the efficiency of residual pressure power generation.

[0004] Depending on the composition of the raw water, the concentrate often contains high concentrations of inorganic salts, complex organic matter, microorganisms, and biological substances. When existing power generation equipment is used to convert the residual pressure in the concentrate discharge pipeline into electrical energy, the inorganic salts in the concentrate are prone to scale formation on the surface of the turbine blades, which leads to an increase in the weight of the blades and an disruption of the turbine's rotational balance, resulting in a decrease in power generation efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide an integrated device for waste pressure power generation and energy storage in a water purification system.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An integrated device for residual pressure power generation and energy storage in a water purification system includes a delivery pipe and a power generation unit connected in series on the delivery pipe. The output end of the power generation unit is connected to an energy storage unit. The power generation unit includes a water turbine and a generator. The water turbine includes a housing and a runner rotatably installed in the housing. The runner is driven by the generator. A vibration component is provided on the runner. The vibration component is used to generate vibration to remove the deposits on the surface of the runner blades.

[0007] The aforementioned integrated device has a branch pipe connected in parallel to the position of the power generation unit on the transmission pipe, and valves are installed at the connection positions of the corresponding branch pipes on the transmission pipe.

[0008] The aforementioned integrated device includes a wheel body and several blades. Each blade is arranged in a circumferential array on the outer wall of the wheel body. Each blade is rotatably connected to the wheel body through a rotating arm. The wheel body is equipped with a drive mechanism that drives each rotating arm to rotate. The vibration component is installed in each rotating arm. When the rotating arm is driven to rotate, the vibration component generates vibration.

[0009] The aforementioned integrated device includes a vibration component comprising a first end face tooth fixed to the inner wall of the wheel body, with each first end face tooth corresponding to a rotating arm. A second end face tooth is slidably mounted on each rotating arm, with the first end face tooth and the corresponding second end face tooth meshing with each other. A spring is also provided inside each rotating arm to maintain the relative position of the second end face tooth and the rotating arm.

[0010] The aforementioned integrated device includes a drive mechanism comprising a first bevel gear rotatably mounted in the wheel body, each rotating arm being connected to the first bevel gear via a second bevel gear, and a drive shaft rotatably mounted on the housing, the drive shaft passing through the wheel body and being connected to the first bevel gear, the drive shaft being driven to rotate to drive the first bevel gear to rotate.

[0011] In the aforementioned integrated device, the drive shaft is a telescopic shaft, and a locking element is provided on the drive shaft to lock the wheel body so that it cannot rotate. The drive shaft has a first state and a second state. In the first state, the drive shaft is disconnected from the first bevel gear and the locking element is in the unlocked state. In the second state, the drive shaft is connected to the first bevel gear and the locking element locks the wheel body.

[0012] The aforementioned integrated device includes a locking component consisting of a telescopic rod fixed to one end of the wheel body. The telescopic rod has a hollow structure, and a friction block is fixed to one end of the telescopic rod. The end of the drive shaft passes through the first bevel gear and is rotatably connected to a Z-shaped rod. The end of the Z-shaped rod away from the drive shaft extends into the telescopic rod and is rotatably connected to the friction block. When the drive shaft extends, the friction block is pushed to contact the fixed seat through the Z-shaped rod.

[0013] The aforementioned integrated device has several cleaning nozzles installed on the inner wall of the housing corresponding to the positions of the blades, and a drain outlet is provided at the bottom of the housing.

[0014] The aforementioned integrated device has a shielding sleeve installed on the inner wall of the housing corresponding to the position of the cleaning nozzle. The shielding sleeve has a first position and a second position along the axial direction of the housing. When it is in the first position, the shielding sleeve blocks the drain outlet and each cleaning nozzle. When it is in the second position, the drain outlet and each cleaning nozzle are exposed.

[0015] In the aforementioned integrated device, the shielding sleeve is fixedly connected to the drive shaft via a connector. When the drive shaft is in the first state, the shielding sleeve is in the first position, and when the drive shaft is in the second state, the shielding sleeve is in the second position.

[0016] In the above technical solution, the integrated power generation and energy storage device provided in the embodiments of the present invention cleans the deposits on the blades by installing a vibration component inside the rotor and using the high-frequency mechanical vibration generated by the vibration component to transmit continuous inertial shear force and alternating stress to the blades of the rotor, thereby physically destroying the interface between the deposits and the blade surface. The deposits are then washed away by water flow, ensuring the power generation efficiency of the device. Attached Figure Description

Detailed Implementation

[0020] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0021] In the description of this invention, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," and "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed or operated in a specific orientation, and therefore should not be construed as a limitation of this invention. In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0022] like Figures 1 to 10As shown in the figure, an integrated device for residual pressure power generation and energy storage for a water purification system is provided in this embodiment of the invention. It includes a delivery pipe and a power generation unit connected in series on the delivery pipe. The output end of the power generation unit is connected to an energy storage unit 1. The power generation unit includes a water turbine 2 and a generator 3. The water turbine 2 includes a housing 21 and a rotor 22 rotatably installed in the housing 21. The rotor 22 is connected to the generator 3 in a transmission manner. A vibration component is provided on the rotor 22. The vibration component is used to generate vibration to remove the adhering substances on the surface of the blades 222 of the rotor 22.

[0023] Specifically, the conveying channel is used to discharge the concentrated water produced by the reverse osmosis water purification system. For ease of description, the end near the concentrated water discharge port in the reverse osmosis water purification system is the first pipe 4, and the end connected to the discharge point is the second pipe 5. The power generation unit is installed between the first pipe 4 and the second pipe 5. The power generation unit includes a water turbine 2 and a generator 3. The water turbine 2 includes a casing 21 and a runner 22. The casing 21 is cylindrical. Figure 3 As shown, a fixed base 211 is fixedly installed in the middle of the housing 21. The rotating wheel 22 is rotatably connected to the fixed base 211. The first pipe 4 connects to the interior of the housing 21 from one end of the outer wall of the housing 21, and the second pipe 5 connects to the interior of the housing 21 from the other end of the outer wall of the housing 21. This allows the concentrated water in the first pipe 4 to flow along the axial direction of the housing 21 and drive the rotating wheel 22 to rotate when it enters the housing 21, before entering the second pipe 5. The generator 3 is installed on the housing 21 at one end of the second pipe 5. A main shaft 31 is fixedly connected to the wheel 22. The main shaft 31 extends through the outside of the housing 21 and is connected to the shaft of the generator 3. The main shaft 31 is dynamically sealed to the housing 21. A vibration assembly is provided on the wheel 22. In this embodiment, the vibration assembly can be an existing vibration motor, which is prior art and can be directly applied without further explanation. The generator 3 is electrically connected to the energy storage unit 1 to ensure that the electricity generated by the generator 3 can be delivered to the energy storage unit 1 for storage. The energy storage unit 1 can be an existing battery, which is prior art and can be directly applied without further explanation.

[0024] The integrated power generation and energy storage device provided in this embodiment of the invention uses a vibration component installed inside the rotor 22 to generate high-frequency mechanical vibrations. By transmitting continuous inertial shear force and alternating stress to the blades 222 of the rotor 22, the bonding interface between the deposits and the surface of the blades 222 is physically destroyed, thereby cleaning the deposits on the blades 222 and using water flow to wash them away, ensuring the power generation efficiency of the device.

[0025] Furthermore, a branch pipe 6 is connected in parallel to the position of the power generation unit on the transmission pipe, and a valve is installed at each connection position of the branch pipe 6 on the transmission pipe.

[0026] Specifically, to facilitate the maintenance of the water turbine 2, in this embodiment, a branch pipe 6 is also connected in series on the delivery pipe, such as... Figure 1 and Figure 2 As shown, one end of branch pipe 6 is connected to the first pipe 4, and the other end of branch pipe 6 is connected to the second pipe 5. A first valve 41 is installed on the first pipe 4 at the connection position of branch pipe 6, and a second valve 51 is installed on the second pipe 5 at the position of branch pipe 6. Both the first valve 41 and the second valve 51 are three-way valves. When the turbine 2 needs to be maintained, the water flow path is switched by the first valve 41 and the second valve 51 so that all the concentrated water is discharged through branch pipe 6.

[0027] In another embodiment of the present invention, the wheel 22 includes a wheel body 221 and a plurality of blades 222. Each blade 222 is arranged in a circumferential array on the outer wall of the wheel body 221. Each blade 222 is rotatably connected to the wheel body 221 through a rotating arm 223. The wheel body 221 is provided with a drive mechanism that drives each rotating arm 223 to rotate. A vibration component is installed in each rotating arm 223. When the rotating arm 223 is driven to rotate, the vibration component generates vibration.

[0028] Furthermore, the vibration assembly includes a first end face tooth 2211 fixed to the inner wall of the wheel body 221. The first end face tooth 2211 is correspondingly arranged with the rotating arm 223. A second end face tooth 2231 is slidably installed on each rotating arm 223. The first end face tooth 2211 and the corresponding second end face tooth 2231 mesh with each other. A spring 2232 is also provided in each rotating arm 223 to maintain the relative position of the second end face tooth 2231 and the rotating arm 223.

[0029] Specifically, in the above embodiment, a vibratory motor is used as the power source. Since it needs to be installed inside the wheel body 221 to protect it from concentrated water, the vibration generated by the vibratory motor cannot be effectively transmitted to the location of the blades 222, resulting in poor impurity removal and significant impact on the various structures within the wheel body 221. In this embodiment, the main structure of the impeller 22 is the wheel body 221, such as... Figure 3 and Figure 4As shown, the wheel body 221 has a hollow structure, and its outer wall is provided with a number of blades 222. There are four groups of blades 222, and each blade 222 is arranged in a circular array around the central axis of the wheel body 221. Each blade 222 is fixedly connected to a rotating arm 223, and the rotating arm 223 is rotatably connected to the wheel body 221. The vibration component includes a first end face tooth 2211 fixed to the inner wall of the wheel body 221. The first end face tooth 2211 is arranged opposite to the end of the rotating arm 223 away from the blades 222. Each rotating arm 223 has... Each arm 223 has a cylindrical hole, and a second end face tooth 2231 is slidably installed on the inner wall of each arm 223. The second end face tooth 2231 slides along the axial direction of the arm 223 it is located in. A spring 2232 is installed in the cylindrical hole on each arm 223. One end of the spring 2232 is fixedly connected to the arm 223, and the other end of the spring 2232 abuts against the surface of its corresponding second end face tooth 2231 to ensure that the second end face tooth 2231 maintains engagement with its corresponding first end face tooth 2211.

[0030] When the rotating arm 223 is driven to rotate, the second end face tooth 2231 can slide along the axial direction of the rotating arm 223, meaning the distance between the second end face tooth 2231 and the first end face tooth 2211 is adjustable. Since the first end face tooth 2211 cannot rotate, the rotating arm 223 will forcefully drive the second end face tooth 2231 to rotate synchronously with it. During this process, as the second end face tooth 2231 rotates relative to the first end face tooth 2211, their tooth surfaces slide relative to each other. The first end face tooth 2211 will forcefully push the second end face tooth 2231 away to ensure that the second end face tooth 2231 can rotate synchronously with the rotating arm 223. The spring 2232 will then push the second end face tooth 2231 to re-engage with the first end face tooth 2211. This results in the rotating arm 223 driving the second end face tooth... During the continuous rotation of 2231, the second end face tooth 2231 will reciprocate at a high frequency within a certain range, thereby generating vibration. The vibration is transmitted directly from the rotating arm 223 to the blade 222, which has a high impurity removal effect and has little impact on the various structures inside the wheel body 221. During normal power generation, the second end face tooth 2231, under the push of the spring 2232, remains engaged with the first end face tooth 2211, which can ensure that the rotating arm 223 will not rotate on its own, thereby avoiding the blade 222 from driving the rotating arm 223 to rotate under the impact of the water flow, which would affect the power generation efficiency. In this embodiment, the cooperation between the first end face tooth 2211 and the second end face tooth 2231 can be used to generate vibration for impurity removal on the one hand, and to limit the rotation of the rotating arm 223 on the other hand.

[0031] In another embodiment of the present invention, the driving mechanism includes a first bevel gear 2212 rotatably mounted in the wheel body 221, each rotating arm 223 being connected to the first bevel gear 2212 via a second bevel gear 2233, and a drive shaft 23 being rotatably mounted on the housing 21. The drive shaft 23 passes through the wheel body 221 and is connected to the first bevel gear 2212. The drive shaft 23 is driven to rotate to drive the first bevel gear 2212 to rotate.

[0032] Specifically, such as Figure 3 , Figure 4 and Figure 7 As shown, the drive mechanism includes a first bevel gear 2212 rotatably mounted inside the wheel body 221. The first bevel gear 2212 is coaxially arranged with the wheel body 221. Second bevel gears 2233 are rotatably mounted inside the wheel body 221 at positions corresponding to the rotating arm 223. Each second bevel gear 2233 meshes with the first bevel gear 2212. The second bevel gears 2233 are coaxially arranged with the rotating arm 223 and the first end face tooth 2211. A rotating shaft 2234 is fixedly connected to the second bevel gear 2233. The end of the rotating shaft 2234 away from the second bevel gear 2233 passes through the first end face tooth 2211 and the second end face tooth 2231 in sequence and is fixedly connected to the inner wall of the rotating arm 223. This achieves the transmission connection between each rotating arm 223 and the first bevel gear 2212. A transmission shaft 23 is rotatably mounted on the housing 21. The transmission shaft 23 is coaxially arranged with the wheel body 221, and one end of the transmission shaft 23 passes through the interior of the wheel body 221 and is connected to the first bevel gear 2212. In this embodiment, a drive motor 24 is installed outside the housing 21 at the position corresponding to the other end of the transmission shaft 23. The output end of the drive motor 24 is fixedly connected to the end of the transmission shaft 23 away from the first bevel gear 2212. This allows the drive motor 24 to drive the first bevel gear 2212 to rotate through the transmission shaft 23, thereby synchronously driving each rotating arm 223 to rotate.

[0033] Furthermore, the transmission shaft 23 is a telescopic shaft, and a locking member 7 is provided on the transmission shaft 23 to lock the wheel body 221 so that it cannot rotate. The transmission shaft 23 has a first state and a second state. When it is in the first state, the transmission between the transmission shaft 23 and the first bevel gear 2212 is disconnected, and the locking member 7 is in the unlocked state. When it is in the second state, the transmission shaft 23 is connected to the first bevel gear 2212, and the locking member 7 locks the wheel body 221.

[0034] Optionally, the transmission shaft 23 includes a first shaft 231 and a second shaft 232. The second shaft 232 is fitted outside the first shaft 231. The first shaft 231 slides along the axial direction of the second shaft 232. A third end face tooth 2311 is fitted on the first shaft 231. The third end face tooth 2311 is fixedly connected to the first shaft 231. A fourth end face tooth 2213 is fixedly connected to the middle of the first bevel gear 2212. The first shaft 231 is driven to move along the axial direction of the second shaft 232 and drives the third end face tooth 2311 to mesh with the fourth end face tooth 2213.

[0035] Furthermore, the locking component 7 includes a telescopic rod 71 fixed to one end of the wheel body 221. The telescopic rod 71 has a hollow structure, and a friction block 72 is fixed to one end of the telescopic rod 71. The end of the drive shaft 23 passes through the first bevel gear 2212 and is rotatably connected to a Z-shaped rod 73. The end of the Z-shaped rod 73 away from the drive shaft 23 extends into the telescopic rod 71 and is rotatably connected to the friction block 72. When the drive shaft 23 extends, the Z-shaped rod 73 pushes the friction block 72 to contact the fixed seat 211.

[0036] Specifically, to avoid affecting the rotation of the rotor 22, the transmission relationship between the drive shaft 23 and the first bevel gear 2212 needs to be completely disconnected during normal power generation, such as... Figure 6 As shown, the transmission shaft 23 is a telescopic shaft, which includes a first shaft 231 and a second shaft 232. The second shaft 232 is fitted outside the first shaft 231 and is rotatably mounted outside the housing 21. The drive motor 24 is connected to the second shaft 232 through a bevel gear set. The end of the first shaft 231 away from the second shaft 232 extends into the wheel body 221. The first shaft 231 can slide along the axial direction of the second shaft 232 and can rotate synchronously with it under the drive of the second shaft 232. A third end face tooth 2311 is fitted on the outer wall of the first shaft 231 at the position corresponding to the first bevel gear 2212, and a fourth end face tooth 2213 is coaxially fixed on the first bevel gear 2212. This allows the drive shaft 23 to have a first state and a second state: In the first state, the transmission shaft 23 is in a retracted state. At this time, the third end face tooth 2311 and the fourth end face tooth 2213 are separated, and the transmission relationship between the transmission shaft 23 and the first bevel gear 2212 is broken. In the second state, the transmission shaft 23 is in an extended state. At this time, the third end face tooth 2311 meshes with the fourth end face tooth 2213, and the transmission relationship between the transmission shaft 23 and the first bevel gear 2212 is established.

[0037] When the first shaft 231 is driven to move along the axial direction of the second shaft 232 toward the side where the first bevel gear 2212 is located (this is forward movement), that is, when the first shaft 231 is... Figure 4In the view, moving horizontally to the left is the forward movement. The transmission shaft 23 switches from the first state to the second state. At this time, the first shaft 231 drives the third end face tooth 2311 to move towards the fourth end face tooth 2213 until the third end face tooth 2311 and the fourth end face tooth 2213 mesh. At this time, the transmission shaft 23 is in the second state. When the drive motor 24 drives the second shaft 232 to rotate, the second shaft 232 drives the first shaft 231 to rotate synchronously, and drives the first bevel gear 2212 to rotate through the engagement of the third end face tooth 2311 and the fourth end face tooth 2213. When the first shaft 231 is driven to move in the opposite direction, the transmission shaft 23 switches from the second state to the first state until the first shaft 231 drives the third end face tooth 2311 to separate from the fourth end face tooth 2213. At this time, the transmission shaft 23 is in the first state.

[0038] Furthermore, to prevent the first bevel gear 2212 from driving the wheel body 221 to rotate synchronously when rotating, thus failing to drive the rotating arms 223 to rotate, a locking element 7 is also provided at the end of the first shaft 231 away from the second shaft 232. The locking element 7 includes a friction block 72 rotatably mounted on the end of the first shaft 231 away from the second shaft 232, such as... Figure 4 and Figure 7 As shown, the first shaft 231 passes through one end of the wheel body 221 and is rotatably connected to the Z-shaped rod 73 through the middle of the first bevel gear 2212. When the first shaft 231 rotates, it does not drive the Z-shaped rod 73 to move. The first shaft 231 and the wheel body 221 are dynamically sealed (the position where the first shaft 231 enters the wheel body 221). The friction block 72 is connected to one end of the corresponding fixed seat 211 of the wheel body 221 through the telescopic rod 71. The telescopic rod 71 has a hollow structure, and its two sections are sleeved together as one piece. The two sections of the telescopic rod 71 cannot rotate relative to each other, but can only extend and retract axially. One end of the telescopic rod 71 is fixedly connected to the friction block 72, and the other end of the telescopic rod 71 is fixedly connected to one end of the corresponding fixed seat 211 of the wheel body 221. Figure 7 As shown, one end of the Z-shaped rod 73 away from the first shaft 231 extends through to the outside of the wheel body 221, and the other end of the Z-shaped rod 73 away from the first shaft 231 extends into the telescopic rod 71 and is fixedly connected to the friction block 72. The wheel body 221 and the fixed seat 211 are dynamically sealed together, and the side of the fixed seat 211 near the wheel body 221 is a hollow structure. When the drive shaft 23 switches from the first state to the second state, the first shaft 231 can also push the friction block 72 towards the inner wall of the fixed seat 211 via the Z-shaped rod 73. When the drive shaft 23 is adjusted to the second state, the friction block 72 is tightly fitted with the inner wall of the fixed seat 211 to prevent the wheel 221 from rotating relative to the fixed seat 211. When the drive shaft 23 is in the first state, the friction block 72 separates from the inner wall of the fixed seat 211, at which time the wheel 221 can rotate relative to the fixed seat 211. For driving the first shaft 231, an existing linear drive mechanism such as an electric actuator can be used. Figure 6 As shown, the electric actuator is set parallel to the first shaft 231, and the output end of the electric actuator is connected to the end of the first shaft 231 through a rod. In order to avoid affecting the rotation of the first shaft 231, the rod needs to be rotatably connected to the first shaft 231.

[0039] In this embodiment, by mounting a third end face tooth 2311 on the first shaft 231 of the transmission rod and fixing a fourth end face tooth 2213 to the middle of the first bevel gear 2212, the relative positions of the third end face tooth 2311 and the fourth end face tooth 2213 are adjusted by moving the first shaft 231, thereby realizing the transmission connection or disconnection between the transmission shaft 23 and the first bevel gear 2212. At the same time, while the first shaft 231 and the first bevel gear 2212 are connected, the wheel body 221 is locked, thereby preventing the wheel body 221 from rotating under the drive of the first bevel gear 2212 and affecting the rotation drive of the rotating arm 223.

[0040] In another embodiment of the present invention, a plurality of cleaning nozzles 212 are provided on the inner wall of the housing 21 at the position corresponding to the blade 222, and a drain outlet 213 is provided at the lower part of the housing 21.

[0041] Specifically, in actual use, vibration alone cannot completely clean the deposits on the blades 222, and it is still necessary to periodically disassemble the rotor 22 to rinse the blades 222. In this embodiment, cleaning nozzles 212 are provided on the inner wall of the housing 21 at positions corresponding to the blades 222. Figure 9 As shown, a distribution cover 214 is provided on the outer wall of the housing 21 corresponding to the position of each cleaning nozzle 212. The distribution cover 214 and the outer wall of the housing 21 form an annular chamber. The annular chamber is connected to each cleaning nozzle 212. Water is supplied to the annular chamber by a water pump, and water can be sprayed from the cleaning nozzle 212 to the blade 222 to achieve rinsing of the blade 222. A drain outlet 213 is provided at the lower part of the housing 21. Optionally, a solenoid valve is provided at the drain outlet 213. When it is necessary to clean the blade 222, the water flow path is switched to the branch pipe 6 by the first valve 41 and the second valve 51, and the solenoid valve is opened to release the concentrated water near the housing 21 of the first pipe 4 and the second pipe 5, as well as the concentrated water in the housing 21. Then, water is supplied to the cleaning nozzle 212 by a water pump. The water flow is ejected at high speed from the cleaning nozzle 212 and washes the deposits on the blade 222. This avoids the complicated operation of disassembling the rotor 22 for cleaning.

[0042] Furthermore, a shielding sleeve 215 is provided on the inner wall of the housing 21 at the position corresponding to the cleaning nozzle 212. The shielding sleeve 215 has a first position and a second position along the axial direction of the housing 21. When it is in the first position, the shielding sleeve 215 shields the drain outlet 213 and each cleaning nozzle 212. When it is in the second position, the drain outlet 213 and each cleaning nozzle 212 are exposed.

[0043] Furthermore, the shielding sleeve 215 is fixedly connected to the drive shaft 23 via a connector. When the drive shaft 23 is in the first state, the shielding sleeve 215 is in the first position. When the drive shaft 23 is in the second state, the shielding sleeve 215 is in the second position.

[0044] Specifically, to prevent impurities in the concentrated water from adhering to the location of the cleaning nozzles 212 and causing blockage, in this embodiment, a shielding sleeve 215 is installed on the inner wall of the housing 21. The outer diameter of the shielding sleeve 215 is equal to the inner diameter of the housing 21, and the shielding sleeve 215 is dynamically sealed to the housing 21. The shielding sleeve 215 has a first position and a second position during its axial movement along the housing 21. When in the first position, the shielding sleeve 215 simultaneously shields the drain outlet 213 and each cleaning nozzle 212. When in the second position, the drain outlet 213 and the cleaning nozzles 212 are fully exposed. At this time, the water inside the housing 21 can be discharged outward from the drain outlet 213 and can also be rinsed by the cleaning nozzles 212. 222; Preferably, the shielding sleeve 215 is fixedly connected to the first shaft 231 of the drive shaft 23 via a connecting member such as a rod. When the drive shaft 23 is in the first state, the shielding sleeve 215 is in the first position, and when the drive shaft 23 is in the second state, the shielding sleeve 215 is in the second position. With this arrangement, the extension and retraction of the drive shaft 23 also drives the movement of the shielding sleeve 215, thereby exposing the drain outlet 213 and each cleaning nozzle 212. The high-pressure water jet from the cleaning nozzle 212 washes the blade 222, and the vibration of the blade 222 achieves cleaning of the blade 222. Since the blade 222 rotates and vibrates at the same time, the blade 222 can be thoroughly washed.

[0045] Furthermore, the first shaft 231 is an elastic telescopic shaft, the third end face tooth 2311 and the Z-shaped rod 73 are both connected to the telescopic section of the first shaft 231, and the shielding sleeve 215 is connected to the fixed section of the first shaft 231.

[0046] Specifically, in the above embodiment, once the transmission relationship between the drive shaft 23 and the first bevel gear 2212 is established, that is, when the third end face tooth 2311 and the fourth end face tooth 2213 mesh, the shielding sleeve 215 no longer blocks the drain outlet 213. This results in the concentrated water in the housing 21 being released each time the blades 222 are cleaned by vibration. In this embodiment, the first shaft 231 is an elastic telescopic shaft, such as... Figure 9As shown, the section of the first shaft 231 connected to the aforementioned electric push rod is a fixed section, while the section on the first shaft 231 where the third end face tooth 2311 and the Z-shaped rod 73 are mounted is a telescopic section. The shielding sleeve 215 is connected to the fixed section of the first shaft 231. During the stroke of the first shaft 231 being driven to move axially along the second shaft 232, the first shaft 231 first drives the third end face tooth 2311 to mesh with the fourth end face tooth 2213, and at the same time, drives the Z-shaped rod 73 to push the friction block 72 to contact the inner wall of the fixed seat 211. During this process... In the middle, the displacement of the shielding sleeve 215 is insufficient to expose the drain outlet 213 and the cleaning nozzle 212; when it is necessary to use the cleaning nozzle 212 to rinse the blades 222, the first shaft 231 will be driven to continue moving on the basis of the above. At this time, the third end face tooth 2311 remains engaged with the fourth end face tooth 2213, and the friction block 72 also remains in contact with the fixed seat 211. Through the contraction of the first shaft 231, the shielding sleeve 215 is further pushed to move, so that the cleaning nozzle 212 and the drain outlet 213 are exposed.

[0047] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
