Description

Technical Field

[0001] This utility model relates to the field of floating debris filtration technology in water conservancy pumping stations, specifically a filtration device for floating debris in water conservancy pumping stations. Background Technology

[0002] Water pumping stations are primarily used for irrigation, water supply, and drainage. By pumping water from lower to higher elevations, they meet the needs of farmland irrigation, urban water supply, flood control, and drainage, ensuring the stability of agricultural production, residents' lives, and the ecological environment. Floating debris filters in water pumping stations are used to intercept, collect, and filter floating debris in the pumping station's water area, preventing it from flowing into the station and clogging components such as pump impellers, thus affecting the station's normal operation.

[0003] Traditional water pumping stations typically use a large intercepting net to filter floating debris and garbage at the pumping station's inlet. This method keeps the floating garbage out of reach. However, to prevent the accumulation of floating garbage, manual cleaning is often necessary, which is labor-intensive and dangerous.

[0004] To address the aforementioned problems, we propose a filtration device for floating debris in water conservancy pumping stations. Utility Model Content

[0005] To address the problems in the background art, this utility model provides a filtration device for floating garbage in water conservancy pumping stations.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A filtration device for floating debris in a water pumping station includes a filter support. Filter screens are located at the center of both ends of the filter support. A water inlet is located at the bottom of the inner cavity of the filter support. Multiple sets of perforated plates are arranged on the outer side of the filter screens, surrounding the filter support and close to the outer surface of the filter screens. A drive assembly is located at the top of the filter support, driving the multiple sets of perforated plates to rotate cyclically around the filter support. The drive assembly includes a track frame, which is installed in a ring on the top of the filter support. Sliding members are located on the top of each set of perforated plates, and these sliding members are slidably installed in the middle of the inner cavity of the track frame, all synchronously driven to rotate cyclically by a traction chain.

[0007] Preferably, the top of the inner cavity of the track frame is provided with a limiting track, and the bottom of the inner cavity of the track frame is provided with a sliding groove.

[0008] Preferably, the top of the sliding member is provided with two sets of limiting pulleys, and the bottom of the sliding member is provided with two sets of rolling pulleys. The limiting pulleys are slidably installed in the limiting track, and the rolling pulleys are slidably installed in the slide groove.

[0009] Preferably, the traction chain is movably installed in the middle of the inner cavity of the track frame. The traction chain is driven by a motor and gears. Multiple sets of sliding members are distributed at equal intervals, and the inner walls of the sliding members are all fixedly connected to the traction chain.

[0010] Preferably, a connecting post is provided at the center of the bottom end of the sliding member, and the hollow plate is fixedly installed at the bottom of the connecting post.

[0011] Preferably, the top of the filter bracket is provided with a support frame, and the track frame is circumferentially fixedly installed on the outer ring of the support frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are: In this solution, multiple sets of perforated plates are set around the filter screen. Then, the drive component drives the multiple sets of perforated plates to rotate around the filter screen in a circular motion. This pushes away the floating garbage accumulated at the filter screen, allowing the floating garbage to float or be collected from both sides of the filter support. This effectively avoids the situation where a large amount of floating garbage accumulates at the filter screen, causing blockage and damage to the filter screen. Attached Figure Description

[0015] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows: Example: Refer to Figure 1 - Figure 5As shown in the figure, a filter device for floating garbage in a water conservancy pumping station according to this embodiment includes a filter support 1. Filter screens 2 are provided at the middle of both ends of the filter support 1. A water inlet 3 is provided at the bottom of the inner cavity of the filter support 1. By setting the water inlet of the water pump at the bottom of the inner cavity of the filter support 1, and by installing filter screens 2 at both ends of the filter support 1, the floating garbage can be effectively intercepted, preventing the floating garbage from entering the water pump and causing blockage.

[0016] Furthermore, by setting multiple sets of perforated plates 4 on the outside of the filter screen 2, the multiple sets of perforated plates 4 surround the outer perimeter of the filter support 1 and are close to the outer surface of the filter screen 2, avoiding direct contact with the filter screen 2 and preventing damage to the filter screen 2 during rotation, while keeping as close as possible to the filter screen 2, so that the accumulated floating garbage can be pushed and moved to the maximum extent during rotation.

[0017] A drive assembly is provided on the top of the filter support 1. The drive assembly is used to drive multiple sets of perforated plates 4 to rotate cyclically around the filter support 1. The drive assembly includes a track frame 6, which is installed in a ring on the top of the filter support 1. Each set of perforated plates 4 is provided with a sliding member 9 on its top. The sliding members 9 are all slidably installed in the middle of the inner cavity of the track frame 6 and are all driven synchronously to rotate cyclically by the traction chain 12. When the perforated plates 4 rotate around the periphery of the filter support 1, they can push and move the floating garbage on the outside of the filter screen 2 to avoid accumulation.

[0018] The track frame 6 has a limiting track 7 at the top of its inner cavity and a sliding groove 11 at the bottom of its inner cavity. The sliding member 9 has two sets of limiting pulleys 8 at its top and two sets of rolling pulleys 10 at its bottom. The limiting pulleys 8 are slidably installed in the limiting track 7, and the rolling pulleys 10 are slidably installed in the sliding groove 11. The limiting track 7 and the sliding groove 11 are mainly used to limit the sliding member 9, enhance the stability of the sliding member 9 during horizontal sliding, and prevent deviation.

[0019] During operation, the traction chain 12 will rotate in a cycle, thereby driving the sliding part 9 to slide in the track frame 6, which in turn drives the bottom hollow plate 4 to rotate around the periphery of the filter support 1, thereby pushing the floating garbage accumulated on the outside of the filter screen 2. When the floating garbage is pushed to the end position on both sides of the filter support 1, it will be carried away by the water flow from the upstream.

[0020] In actual use, collection nets can be installed at both ends of the filter bracket 1 to collect and recycle the floating garbage that is pushed over.

[0021] In some examples, the traction chain 12 is movably installed in the middle of the inner cavity of the track frame 6. The traction chain 12 is driven by a motor and gears. The connection method of the motor, gears and traction chain 12 is a mature existing technology and will not be described in detail. It is mainly used to drive the traction chain 12 to perform cyclic rotation in the track frame 6.

[0022] In some examples, multiple sets of sliders 9 are equidistantly distributed, and the inner walls of the sliders 9 are all fixedly connected to the traction chain 12.

[0023] In some examples, a connecting post 13 is provided at the bottom center of the slider 9, and the hollow plate 4 is fixedly installed at the bottom of the connecting post 13.

[0024] In some examples, a support frame 5 is provided on the top of the filter bracket 1, and a track frame 6 is circumferentially fixed on the outside of the support frame 5. The support frame 5 mainly serves to support the track frame 6, so that it can be stably installed on the top of the filter bracket 1.

[0025] In some examples, the perforated plate 4 is designed with a perforated structure, which can reduce resistance when moving in water.

[0026] The working principle of this utility model is as follows: Firstly, by installing filter screens 2 at both ends of the filter bracket 1, floating debris in the water can be filtered out, preventing it from flowing into the inlet 3 and causing damage to the water pump impeller.

[0027] In addition, the drive component drives multiple sets of perforated plates 4 to rotate around the periphery of the filter screen 2. Under the action of water buoyancy, the floating garbage accumulated on the filter screen 2 is pushed away, so that the floating garbage floats or is collected from both sides of the filter support 1, avoiding the accumulation of a large amount of floating garbage on the filter screen 2, which would cause blockage or other damage to the filter screen 2.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
