Description

Technical Field

[0001] This utility model relates to the field of filtration device technology, and in particular to a filtration device for water conservancy and hydropower. Background Technology

[0002] Water conservancy and hydropower engineering focuses on the planning, design, construction, management, and scientific research of large and medium-sized water conservancy and hydropower hubs and their structures, as well as industrial water-using structures. Research directions include hydrology and water resources, water environment, hydraulic structures, hydraulics and fluid dynamics, and engineering management. The development trend is the intersection and integration with emerging disciplines such as information technology, reliability theory, and management science. Floating debris in large dams can affect the operation of water turbines. In existing technologies, filter screens are usually used to filter floating debris on the water surface. The filter screens block the debris on the water intake side, reducing the impact on the water turbines.

[0003] Existing filtration devices tend to become clogged after a period of use, affecting filtration efficiency. Furthermore, existing filtration devices are not convenient for automatically cleaning debris from the filter screen surface. Therefore, we propose a filtration device for water conservancy and hydropower projects that can avoid filter screen clogging and facilitate debris cleaning. Utility Model Content

[0004] The purpose of this utility model is to solve the problems in the prior art by proposing a filtration device for water conservancy and hydropower.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A filtration device for water conservancy and hydropower includes a water conveying channel and a filtration assembly disposed within the water conveying channel. The water conveying channel includes a first channel and a second channel. The filtration assembly includes a filter cylinder that rotates within the first channel. The filter cylinder is used to filter the water flowing in the second channel. The filter cylinder is equipped with a spiral pusher plate for discharging waste inside. A high-pressure spray pipe for rinsing the filter cylinder is disposed on the upper side of the filter cylinder.

[0007] In some embodiments, the first flow channel and the second flow channel form a stepped shape, and the second flow channel is provided with an extension plate flush with the first flow channel at one end.

[0008] In some embodiments, the filter cartridge is rotatably mounted on the upper surface of the first flow channel via a support frame. The end of the filter cartridge away from the second flow channel is funnel-shaped, and the end of the filter cartridge near the second flow channel is fixedly fitted with an annular track. The filter cartridge rotates on the surfaces of two support wheels via the annular track.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-5 A filtration device for water conservancy and hydropower includes a water conveying channel 1 and a filter assembly 2 disposed within the water conveying channel 1. The water conveying channel 1 includes a first channel 101 and a second channel 102, which are stepped and arc-shaped. The first channel 101 and the second channel 102 are concentrically arranged. The diameter of the first channel 101 is larger than the diameter of the second channel 102. An extension plate 103, flush with the first channel 102, is disposed at one end of the second channel 102 near the first channel 101. The filter assembly 2 includes a filter cylinder 201 that rotates within the first channel 101. Two support wheels 202 are symmetrically fixed on the upper surface of the first channel 101. A filter is fixedly mounted at one end of the filter cylinder 201 near the second channel 102. The filter cylinder 201 rotates on the surface of two support wheels 202 via the annular track 203. Both support wheels 202 are located below the central axis of the filter cylinder 201. The central axes of the first flow channel 101 and the second flow channel 102 are located below the central axis of the filter cylinder 201. A support frame 3 is rotatably attached to the end of the filter cylinder 201 away from the second flow channel 102. The support frame 3 is fixedly connected to the upper surface of the first flow channel 101. The filter cylinder 201 is driven to rotate by the drive assembly 4. The end of the filter cylinder 201 away from the second flow channel 102 is funnel-shaped. Both ends of the filter cylinder 201 are open. A retaining ring is provided at the inner end of the filter cylinder 201 near the second flow channel 102. The extension plate 103 extends into the interior of the filter cylinder 201 at the end near the filter cylinder 201.

[0025] It is understandable that the filter cylinder 201 is driven to rotate on the surface of the support frame 3 by the drive component 4. At the same time, the filter cylinder 201 rolls on the surface of the two support wheels 202 via the track 203, so that the water in the second flow channel 102 flows into the filter cylinder 201 through the extension plate 103. The water is filtered by the rotation of the filter cylinder 201, and the filtered water flows to the water turbine through the first flow channel 101. By setting the baffle ring, the garbage in the filter cylinder 201 is prevented from flowing out.

[0026] Specifically, the drive assembly 4 includes a dual-head motor 401 fixed on the surface of the support frame 3, a gear ring 403 fixedly mounted on the surface of the filter cartridge 201, and a gear 402 fixedly connected to the output end of the dual-head motor 401 near the gear ring 403, with the gear 402 meshing with the gear ring 403.

[0027] It is understandable that the dual-head motor 401 operates, thereby driving the gear 402 to rotate. Under the meshing relationship between the gear 402 and the gear ring 403, the filter cartridge 201 is driven to rotate, thus performing the filtration work.

[0028] Specifically, a spiral pusher plate 5 is rotatably installed inside the filter cylinder 201. The spiral pusher plate 5 is located at the end of the filter cylinder 201 away from the second flow channel 102. The spiral pusher plate 5 rotates on the surface of the support frame 3 via a connecting shaft. The spiral pusher plate 5 cooperates with the filter cylinder 201. A synchronous wheel 6 is fixedly connected to the outer end of the connecting shaft. Another synchronous wheel 6 is fixedly connected to the output end of the dual-head motor 401 away from the gear 402. Both synchronous wheels 6 are connected by a synchronous belt 7. A guide plate 11 is fixedly connected to the upper surface of the first flow channel 101. One end of the guide plate 11 is located below the outlet end of the filter cylinder 201, and the other end of the guide plate 11 is located outside the first flow channel 101. The end of the guide plate 11 near the filter cylinder 201 is higher than the outer end of the guide plate 11.

[0029] Understandably, the dual-head motor 401 operates, driving the connecting shaft and the spiral pusher plate 5 to rotate under the action of the two synchronous pulleys 6 and the synchronous belt 7. Since the spiral pusher plate 5 is driven by the synchronous belt 7 and the synchronous pulleys 6, its rotation direction is the same as that of the dual-head motor 401. However, the filter cartridge 201 is driven by the engagement of the gear 402 and the gear ring 403, resulting in its rotation direction being opposite to that of the dual-head motor 401. Therefore, the rotation direction of the filter cartridge 201 is opposite to that of the spiral pusher plate 401. The pusher plate 5 rotates in the opposite direction. Through the rotation of the spiral pusher plate 5, the garbage in the filter cylinder 201 can be driven to the outlet of the filter cylinder 201 for discharge, thus preventing the accumulation of garbage in the filter cylinder 201. At the same time, when the water flows into the filter cylinder 201 through the second flow channel 102 and the extension plate 103, the impact of the water flow can flush the garbage towards the spiral pusher plate 5, making it easier to clean the garbage. By setting the guide plate 11, it is easy to collect the garbage discharged from the outlet of the filter cylinder 201 and discharge it into the range of the first flow channel 101.

[0030] Specifically, a high-pressure spray pipe 8 for rinsing the outer surface of the filter cartridge 201 is fixedly connected to the surface of the support frame 3. A water pump 9 is fixedly connected to the surface of the support frame 3. One end of the water pump 9 is connected to one end of the high-pressure spray pipe 8. One end of the water pump 9 is connected to a flexible hose. The lower end of the flexible hose hangs down into the first flow channel 101. A baffle plate 10 is fixedly connected to the upper surface of the first flow channel 101. The baffle plate 10 is located on the side close to the high-pressure spray pipe 8.

[0031] Understandably, the water pump 9 operates, and the water filtered in the first flow channel 101 is transported to the high-pressure spray pipe 8 through the hose. The high-pressure spray pipe 8 backwashes the surface of the filter cylinder 201. At the same time, the filter cylinder 201 rotates continuously to prevent it from clogging. The baffle plate 10 is set to prevent water sprayed on the surface of the filter cylinder 201 from splashing.

[0032] In this invention, water flows into the filter cylinder 201 through the second flow channel 102 and the extension plate 103. Simultaneously, the dual-head motor 401 operates, driving the filter cylinder 201 and the spiral pusher plate 5 to rotate in opposite directions. The dual-head motor 401 drives the filter cylinder 201 to rotate via gears 402 and gear rings 403. The filter cylinder 201 rolls on the surfaces of two support wheels 202 via the track 203, filtering the water. The filtered water then flows through the first flow channel 101 to the water turbine. The dual-head motor 401 drives the connecting shaft and the spiral pusher plate 5 to rotate via two synchronous pulleys 6 and a synchronous belt 7, carrying debris from the filter cylinder 201 to the outlet of the filter cylinder 201 for discharge, thus preventing debris accumulation inside the filter cylinder 201. Meanwhile, when water flows into the filter cylinder 201 through the second flow channel 102 and the extension plate 103, the impact of the water flow can flush the garbage towards the spiral push plate 5, making it easier to clean the garbage. Under the action of the guide plate 11, the garbage discharged from the outlet of the filter cylinder 201 is collected and discharged from the range of the first flow channel 101. Then, the water pump 9 is activated, and under the action of the hose, the filtered water in the first flow channel 101 is transported to the high-pressure spray pipe 8. The surface of the filter cylinder 201 is backwashed through the high-pressure spray pipe 8. At the same time, the filter cylinder 201 continues to rotate, which can prevent the filter cylinder 201 from clogging. Under the action of the baffle plate 10, the water sprayed on the surface of the filter cylinder 201 is prevented from splashing.
