Description

Technical Field

[0001] This invention belongs to the field of cleaning equipment technology, specifically relating to an environmentally friendly and energy-saving cleaning device for water conservancy projects. 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 a precious resource that is indispensable for human production and life, but its natural state does not fully meet human needs. Only by constructing water conservancy projects can water flow be controlled, floods prevented, and water volume regulated and distributed to meet the needs of people's lives and production for water resources. Water conservancy projects require the construction of different types of hydraulic structures such as dams, dikes, spillways, sluice gates, intakes, canals, ferries, raft channels, and fishways to achieve their goals.

[0003] In water conservancy projects, inlets and outlets are typically installed, with gates at both locations to block the flow of water on either side. However, in some current aquatic environments, due to excessive human interference, the aquatic environment is gradually changing, and various floating objects are frequently seen on the water surface. During flood discharge or drainage, these floating objects accumulate at the outlet. Over time, various foreign objects accumulate on the water surface, in the water, and at the bottom. Foreign objects at the bottom or in the water, unlike those on the surface, cannot be contained and accumulate; they simply flow into the next aquatic environment, causing pollution transfer.

[0004] To address the aforementioned problems in the current aquatic environment, regular cleaning and salvage operations are necessary to maintain its cleanliness. However, current methods are relatively limited, relying on manual labor or boats for salvage. This approach increases costs and cannot be implemented in real-time, especially in flowing water where floating debris can move. While interception mechanisms at the outlet can filter floating debris, this technology can only intercept a small amount, and excessive interception can affect water flow and the discharge rate. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies and provide an environmentally friendly and energy-saving cleaning device for water conservancy projects. The device includes a filtration unit and a disinfection unit. The filtration unit comprises a filter plate, a filter cylinder, and a rotating cleaning mechanism. The filter cylinder is mounted on the filter plate and has a receiving cavity inside. The rotating cleaning mechanism includes a rotating drive unit, a membrane filtration unit, and an ultrasonic unit. Both the membrane filtration unit and the ultrasonic unit are located within the receiving cavity. The rotating drive unit is located on the lower outer side of the filter cylinder and suspended from the filter plate. The ultrasonic unit is fixedly mounted on the inner wall of the filter cylinder. The rotating drive unit drives the membrane filtration unit to rotate relative to the ultrasonic unit within the filter cylinder. During rotation, the membrane filtration unit causes disordered turbulence in the filtering fluid within the receiving cavity. The ultrasonic unit increases the disorder of this turbulence, thereby increasing fluid flow and turbulent disturbance.

[0006] The membrane filtration unit includes a hollow rotating shaft and multiple filter membranes. The upper part of the hollow rotating shaft is disposed inside the filter cartridge, and the lower part of the hollow rotating shaft extends out of the filter cartridge. The hollow rotating shaft and the filter cartridge are sealed together by a mechanical seal assembly, which is a standard accessory in this field and will not be described in detail here. The rotary drive unit includes a drive motor and a reducer. The drive motor is preferably an asynchronous motor. The drive shaft of the drive motor is connected to the reducer, which is a parallel shaft reducer. The reducer is connected to the lower part of the hollow rotating shaft through a hollow shaft locking device. The hollow rotating shaft has a permeate channel inside, and a permeate outlet is provided at the end of the hollow rotating shaft that extends out of the filter cartridge. The permeate outlet communicates with the permeate channel.

[0007] Multiple filter membranes are divided into two or three equal groups, with each group evenly spaced on a hollow rotating shaft. Taking two groups of six filter membranes each as an example, the extension direction of the filter membranes is perpendicular to the axial direction of the hollow rotating shaft. The six filter membranes in the same group are evenly spaced vertically and fixed by a stacking plate. The bottom and top filter membranes are fastened by a lower limit plate and an upper limit plate, respectively. The filter membranes are sealed to the lower limit plate, the upper limit plate, and the stacking plate. The membrane filtration unit in this embodiment adopts a modular design, allowing for individual replacement of the filter membranes, thus offering high flexibility.

[0008] All filter membranes are arranged in parallel, with cross-flow channels formed between adjacent membranes. These channels connect to the receiving cavity of the filter cartridge, facilitating the entry and exit of the filtered fluid. Filter pores are provided on the surface of the membranes, and permeate channels are located within the membranes. The filter pores are connected to the permeate outlet via the permeate and permeate channels. The membrane filtration unit rotates under the drive of a rotary drive unit, creating a disordered turbulent flow that is not aligned with the filtration direction. This prevents the deposition of particulate matter on the membrane surface, thus reducing membrane fouling.

[0009] The beneficial effects of this invention include: This invention provides an environmentally friendly and energy-saving cleaning device for water conservancy projects, comprising: a filtration device and a disinfection device. The filtration device includes a filter plate, a filter cylinder, and a rotating cleaning mechanism. The filter cylinder is mounted on the filter plate and has a receiving cavity inside. The rotating cleaning mechanism includes a rotating drive unit, a membrane filtration unit, and an ultrasonic unit. Both the membrane filtration unit and the ultrasonic unit are located within the receiving cavity. The rotating drive unit is located on the lower outer side of the filter cylinder and suspended from the filter plate. The ultrasonic unit is fixedly mounted on the inner wall of the filter cylinder. The rotating drive unit drives the membrane filtration unit to rotate relative to the ultrasonic unit within the filter cylinder. During the rotation of the membrane filtration unit, disordered turbulence is generated in the filtration fluid within the receiving cavity. The ultrasonic unit increases the disorder of this turbulence, thereby increasing fluid flow and turbulent disturbance, purifying and filtering aquatic plants and decaying pollutants, and improving the water purification rate.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0013] Example 1 This invention discloses an environmentally friendly and energy-saving cleaning device for water conservancy projects, comprising: a filtration device 1 and a disinfection device 2. The filtration device 1 includes a filter plate 11, a filter cylinder 12, and a rotating cleaning mechanism 13. The filter cylinder 12 is mounted on the filter plate 11 and has a receiving cavity inside. The rotating cleaning mechanism 13 includes a rotating drive unit, a membrane filtration unit, and an ultrasonic unit. Both the membrane filtration unit and the ultrasonic unit are located within the receiving cavity. The rotating drive unit is located on the lower outer side of the filter cylinder 12 and suspended from the filter plate 11. The ultrasonic unit is fixedly mounted on the inner wall of the filter cylinder 12. The rotating drive unit drives the membrane filtration unit to rotate relative to the ultrasonic unit within the filter cylinder 12. During the rotation of the membrane filtration unit, disordered turbulence is generated in the filtered fluid within the receiving cavity. The ultrasonic unit increases the disorder of the turbulence, thereby increasing fluid flow and turbulent disturbance.

[0014] The membrane filtration unit includes a hollow rotating shaft and multiple filter membranes. The upper part of the hollow rotating shaft is disposed inside the filter cartridge 12, and the lower part of the hollow rotating shaft extends out of the filter cartridge 12. The hollow rotating shaft and the filter cartridge 12 are sealed together by a mechanical seal assembly, which is a standard accessory in this field and will not be described in detail here. The rotary drive unit includes a drive motor and a reducer. The drive motor is preferably an asynchronous motor. The drive shaft of the drive motor is connected to the reducer, which is a parallel shaft reducer. The reducer is connected to the lower part of the hollow rotating shaft by a hollow shaft locking device. The hollow rotating shaft has a permeate channel inside, and a permeate outlet is provided at the end of the hollow rotating shaft that extends out of the filter cartridge 12. The permeate outlet communicates with the permeate channel.

[0015] Multiple filter membranes are divided into two or three equal groups, with each group evenly spaced on a hollow rotating shaft. Taking two groups of six filter membranes each as an example, the extension direction of the filter membranes is perpendicular to the axial direction of the hollow rotating shaft. The six filter membranes in the same group are evenly spaced vertically and fixed by a stacking plate. The bottom and top filter membranes are fastened by a lower limit plate and an upper limit plate, respectively. The filter membranes are sealed to the lower limit plate, the upper limit plate, and the stacking plate. The membrane filtration unit in this embodiment adopts a modular design, allowing for individual replacement of the filter membranes, thus offering high flexibility.

[0016] All filter membranes are arranged in parallel, with cross-flow channels formed between adjacent membranes. These channels communicate with the receiving cavity of the filter cartridge 12, facilitating the entry of the filtered fluid. Filter pores are provided on the surface of the filter membranes, and permeate channels are provided within the membranes. The filter pores are connected to the permeate outlet via the permeate and permeate channels. The membrane filtration unit rotates under the drive of the rotary drive unit, creating a disordered turbulent flow that is not in the filtration direction. This prevents the deposition of particulate matter on the membrane surface, thus reducing membrane fouling.

[0017] The disinfection device 2 includes a disinfection cylinder 21, a disinfection cover 22, a disinfection light emitter, and a fan. The disinfection cover 22 is disposed inside the disinfection cylinder 21 and has a first disinfection channel. The disinfection cylinder 21 is provided with an air inlet and an air outlet that are respectively connected to the outside. The air inlet, the first disinfection channel, and the air outlet are connected in sequence. The fan is disposed between the air inlet and the air outlet to draw airflow from the air inlet into the first disinfection channel and discharge it from the air outlet.

[0018] The disinfection hood 22 has a reflective surface constructed in the shape of a ring-shaped paraboloid. The disinfection hood 22 has a disinfection inlet and a disinfection outlet spaced apart along the central axis Y of the ring-shaped paraboloid. The space between the disinfection inlet and the disinfection outlet is a first disinfection channel. The ring-shaped paraboloid has a first focal point F1 and a second focal point F2. The disinfection light emitter is positioned on the line connecting the first focal point F1 and the second focal point F2 and is configured to emit light towards the reflective surface to reduce the number of reflections of the light emitted by the disinfection light emitter through the reflective surface, thereby allowing the emitted light to illuminate the reflective surface and be emitted through reflection.

[0019] Due to the optical properties of a parabola, light rays emitted from its focal point are reflected by the parabola and emitted in a direction parallel to the axis of symmetry. Therefore, by positioning the light rays along the line connecting the first focal point F1 and the second focal point F2, as many disinfection rays as possible can be emitted from the focal point and its vicinity, thus ensuring that as many disinfection rays as possible are emitted in a direction parallel to the axis of symmetry. Since the disinfection light emitter has a certain length and width, it is impossible to emit light only from two focal points. When the disinfection light rays are emitted from near the focal point onto the reflective surface at one end of the disinfection hood 22, they are reflected in a direction slightly inclined to the axis of symmetry of the parabola, causing the disinfection light rays to be emitted as far as possible towards the other end of the disinfection hood 22, thereby minimizing the number of times the disinfection light rays are reflected by the reflective surface. Therefore, the number of times the same disinfection light ray is reflected by the reflective surface can be minimized, and the path taken by the disinfection light rays can be shortened, thereby reducing the attenuation of the disinfection light rays when passing through the first disinfection channel and increasing its disinfection and sterilization effect on the airflow. Throughout the entire disinfection and sterilization process of disinfection device 2, the disinfection light will not leak to the outside, allowing for sterilization at the site of personnel activity, thus enhancing its applicability. Furthermore, the flowing airflow can carry away the heat generated by the disinfection light emitter during operation, extending its lifespan and reducing light decay.

[0020] During the rotation of the filter sleeve, the L-shaped plate at the bottom of the filter sleeve rotates synchronously. During this rotation, the combined track within the L-shaped plate moves, and the inner groove and outer protrusion of the combined track continuously contact the guide wheel at the bottom. The guide wheel acts as a guide. The inner groove and outer protrusion are at different heights, which allows the arched plate, equipped with the guide wheel, to move vertically up and down. The bristles in the arched plate continuously contact the inner wall of the filter sleeve. Since the bristles are soft, they can better insert into the filter holes, effectively cleaning clogged impurities. Furthermore, because the filter sleeve rotates while the arched plate moves vertically, the bristles in the arched plate can effectively clean the inner wall of the filter sleeve.

[0021] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments that can be applied to other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
