Description

Technical Field

[0001] This application relates to river pollution interception, and more particularly to a sewage interception device for pumping stations. Background Technology

[0002] With socio-economic development and rapid urban expansion and population growth, various problems have arisen, including mixed connections between municipal and commercial facilities, businesses, residential areas, and other sources of stormwater and sewage. Some urban sewage is connected to stormwater drainage networks and discharged centrally through municipal pumping stations during rainy days, causing significant pollution to urban rivers. This results in large amounts of nitrogen, phosphorus, and organic matter being discharged into rivers without interception or treatment, leading to widespread blackening and foul odors in waterways. This causes rapid deterioration of urban river water quality and aquatic ecosystems, a sharp drop in dissolved oxygen, and the death of aquatic animals such as fish and shrimp. Simultaneously, the large-scale discharge of pollutants into rivers causes a sharp drop in dissolved oxygen and a rapid increase in pollutants such as ammonia nitrogen and total phosphorus, resulting in turbidity, reduced water transparency, and loss of water body function. Furthermore, due to the complex and interconnected nature of municipal drainage systems, a complete overhaul of these systems is impossible in the short term. Moreover, the dynamic nature of urban stormwater and sewage connections means that water pollution from municipal pumping stations remains a major cause of urban river pollution.

[0003] The primary function of municipal pumping stations is to centrally discharge rainwater collected from stormwater pipes. Therefore, municipal discharges into rivers are characterized by irregular discharges, with large-scale discharges occurring in short periods during heavy rain. Previous river water management methods, such as dredging, interception and pipe laying, and ecological restoration, are ineffective against discharges from municipal pumping stations when the river water quality is good and the ecosystem is healthy during clear weather. Without interception and treatment of the discharged wastewater, large areas of water will become polluted, leading to deterioration of water quality and appearance, impacting aquatic life, and damaging the aquatic ecosystem and environment.

[0018] Figure 2 The diagram shown is a schematic representation of the interior of the channel steel in an embodiment of this utility model. Detailed Implementation

[0019] The technical solutions of the present utility model will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Combination Figure 1-2 As shown, the sewage interception device 100 of the pumping station includes channel steel 101 with openings facing each other on both sides of the river channel. An isolation canvas 102 is provided between the two channel steels 101. Both ends of the isolation canvas 102 extend into the interior of the channel steel 101. A floating sewage interception belt 103 is provided on the top of the isolation canvas 102, and a counterweight block 104 is hung on the bottom of the isolation canvas 102.

[0021] In this embodiment, a floating debris barrier can effectively intercept surface debris. This barrier automatically rises and falls according to water level, and can automatically adjust for tidal influences in waterways, making it highly efficient and reliable. A seeding block at the bottom effectively prevents the barrier from shifting.

[0022] Furthermore, multiple counterweights 104 are provided and arranged and suspended at the bottom of the isolation canvas 102.

[0023] In this embodiment, multiple layers are evenly arranged to ensure the unfolded state of the isolation canvas and to ensure uniform force distribution.

[0024] Furthermore, a plurality of one-way windows 105 are provided in the middle of the isolation canvas 102, and a partition curtain 113 is formed at the top of the one-way window 105, which closes the one-way window 105.

[0025] In this embodiment, the partition curtain, also known as the soft-pump door, allows water to flow in one direction without affecting the free raising, lowering, and folding of the isolation fabric. It achieves unidirectional water flow, similar to the principle of an air pump; water can only flow in one direction, and the reverse flow is blocked by the partition curtain. The unidirectional window ensures water flow and reduces its impact on the overall fabric. Furthermore, the unidirectional flow helps intercept sewage. This device is mainly installed at the point where a tributary and the main river are about to connect. Water can only flow from the tributary to the main river. When the main river is polluted, the sewage can be effectively blocked outside the interception device because the water can only flow from the tributary to the main river, effectively intercepting sewage discharged from the pumping station. The frame of the unidirectional window 105 is wrapped with magnetic stainless steel strips, and the frame of the partition curtain 113 is also wrapped with magnetic stainless steel strips. When the water level in the main river is high, the unidirectional soft-pump door (partition curtain 113) automatically closes due to water pressure and magnetic action, ensuring the water-blocking effect and preventing excessive deformation that could lead to a loss of water-blocking capability.

[0026] Furthermore, floating pulleys 106 are provided at both ends of the floating debris barrier 103, and the floating pulleys 106 are located inside the channel steel 101.

[0027] In this embodiment, the floating pulley improves the efficiency of floating. Initially, it is only necessary to loosen the steel wire rope and loosen the isolation canvas to a soft fold state to achieve automatic floating.

[0028] Furthermore, the bottom of the isolation canvas 102 is provided with two first fixed pulleys 107, and also includes an electric lift 108 set on the top of the two channel steels 101 and a second fixed pulley 109 set inside the channel steels 101, and a wire rope 110 that connects the electric lift 108, the first fixed pulleys 107, the second fixed pulleys 109 and the floating debris barrier 103 in sequence.

[0029] In this embodiment, when the water flow is large or the water level is high and affects the release of the flow, the floating debris barrier is pulled down below the water level by starting the elevator. Due to the heavy counterweight underneath, when the elevator is in operation, it will pull the floating debris barrier down as a whole to a position below the water level, thus releasing the river flow.

[0030] Furthermore, a vertical steel pipe 111 is connected below the first fixed pulley 107.

[0031] In this embodiment, the vertical steel pipe serves a fixing function, being inserted into the riverbed to improve the overall stability of the structure.

[0032] Furthermore, the channel steel 101 is galvanized channel steel 101. The isolation canvas 102 is ultra-high molecular weight polyethylene fiber cloth.

[0033] In this embodiment, corrosion resistance is improved. Furthermore, due to its high specific strength and high specific modulus, the ultra-high molecular weight polyethylene fiber cloth exhibits outstanding impact and cut resistance, can withstand water flow impact, is waterproof, effectively blocks sewage, has low density, floats on water, and is easy to lift and lower. It is also resistant to chemical corrosion and ultraviolet radiation, making it suitable for long-term use in river water bodies.

[0034] Furthermore, the floating debris barrier 103 floats 20-40 centimeters above the water surface.

[0035] In this embodiment, since it is necessary to effectively intercept garbage on the water surface, the floating debris barrier floats above the water surface, thus enabling effective interception.

[0036] Furthermore, multiple fasteners 112 are provided on the steel wire rope 110 and the isolation canvas 102.

[0037] In this embodiment, a stable connection is ensured between the steel wire rope and the insulating canvas, making it secure when pulled down.
