Description

Technical Field

[0001] The present invention belongs to the technical field of construction engineering, and particularly relates to a rainwater inlet garbage grading protection device and a construction method therefor. Background Art

[0002] When installing the rainwater grate at the rainwater inlet synchronously during the last process of improving the municipal road, a prefabricated iron rainwater grate from the manufacturer is used to protect the garbage at the rainwater inlet, ensuring that leaves, stones, solid plastic garbage, etc. at the drainage outlet of the municipal road can be effectively intercepted during the rainy season, thereby ensuring smooth drainage at the rainwater inlet. The current rainwater inlet garbage protection has the following technical problems: The traditional rainwater grate mainly uses a single grid structure, which can only block large-volume garbage (such as beverage bottles), and lacks effective interception of small-particle garbage such as fine sand and leaves, resulting in frequent pipeline blockages; The space of the rainwater well chamber is narrow, and it is difficult to clean up the accumulated garbage. It is necessary to frequently manually open the rainwater grate, which causes the bolts of the grate to loosen and be damaged, and the cleaning efficiency is low. The above problems urgently require a rainwater inlet garbage grading protection device and a construction method therefor. Summary of the Invention

[0003] To solve the above technical problems, the present invention provides a rainwater inlet garbage grading protection device and a construction method therefor, which are particularly suitable for blocking small-volume garbage in the protection of garbage at the rainwater inlet.

[0004] The technical solution adopted by the present invention is as follows: In the first aspect, a rainwater inlet garbage grading protection device is provided, including:

[0005] A bottom storage member;

[0006] A bottom filter member, disposed at the bottom of the bottom storage member;

[0007] A filtering unit for filtering rainwater and garbage, and the filtering unit is connected to the bottom filter member.

[0008] Further, the filtering unit includes a top support frame, at least two first-stage filtering members, and at least two lateral auxiliary filtering members. The top support frame adapts to the shape of the top of the bottom storage member. One end of one first-stage filtering member is connected to one end of another first-stage filtering member, and the other ends of all the first-stage filtering members are connected to the lower end of the top support frame. The lateral auxiliary filtering members cover the voids formed by the top support frame and the first-stage filtering members.

[0009] Further, the filtering gap of the bottom filter member is smaller than the filtering gap of the first-stage filtering member, and the filtering gaps of the first-stage filtering member and the lateral auxiliary filtering member are the same.

[0010] Further, the filtering unit further includes at least two secondary filtering members. One end of each secondary filtering member is connected to one end of the primary filtering member, and the other end is connected to the end of the bottom filtering member. The filtering gaps of the primary filtering member, the secondary filtering members, and the bottom filtering member decrease in sequence.

[0011] Further, hydrophobic coatings are covered on the surfaces of the primary filtering member, the secondary filtering members, the lateral auxiliary filtering member, and the bottom filtering member.

[0012] Further, handles are provided at both ends of the top support frame.

[0013] In a second aspect, a construction method of a rainwater inlet garbage grading protection device is provided, including:

[0014] Lift the handle and place the assembled filtering unit into the bottom storage member;

[0015] Connect the secondary filtering member to the bottom filtering member;

[0016] Lift the handle and place the entire rainwater inlet garbage grading protection device into the rainwater inlet well chamber.

[0017] The advantages and positive effects of the present invention are as follows: Due to the adoption of the above technical solutions, by combining the primary filtering member and the lateral auxiliary filtering member into a three-dimensional filtering space, the filtering area is expanded, and the garbage accumulation efficiency is improved in cooperation with gravity; through the combination of the primary filtering member, the secondary filtering members, and the bottom filtering member, hierarchical multi-stage interception is realized, further improving the garbage interception efficiency and the possibility of preventing garbage blockage; by covering hydrophobic coatings on each filtering member, since the hydrophobic coatings have extremely low surface energy, the intermolecular force between the garbage particles and the mesh plate is significantly weakened.

[0029] The present disclosure will be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the present disclosure are illustrated. The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure. It is obvious that the described embodiments are only a part of the embodiments of the present disclosure, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present disclosure without creative efforts shall fall within the protection scope of the present disclosure.

[0030] As Figure 1-2 shown, the present invention provides a rainwater inlet garbage grading protection device, including a bottom storage member 10, a bottom filter member 20 and a filter unit 30. The bottom filter member 20 is arranged at the bottom of the bottom storage member 10. The filter unit 30 is used for filtering rainwater and garbage, and the filter unit 30 is connected to the bottom filter member 20.

[0031] With the above device, the rainwater and garbage flowing into the rainwater inlet are filtered by the filter unit, and the garbage is stored in the bottom storage member while the rainwater passes through smoothly, preventing the rainwater inlet from being blocked.

[0032] In order to solve the problem that traditional rainwater filtering devices are mainly planar grille structures, and the drainage capacity is lost when the surface of the grille structure is covered with garbage, an implementation method is provided in this embodiment.

[0033] As Figure 3 shown, in one embodiment, the filter unit 30 includes a top support frame 31, at least two primary filter members 32, and at least two lateral auxiliary filter members 33. The top support frame 31 is adapted to the shape of the top of the bottom storage member 10. One end of one primary filter member 32 is connected to one end of another primary filter member 32, and the other ends of all the primary filter members 32 are connected to the lower end of the top support frame 31. The lateral auxiliary filter members 33 cover the gaps formed by the top support frame 31 and the primary filter members 32.

[0034] Using the above device, the primary filter element and the lateral auxiliary filter element are combined into a three-dimensional filtering space, expanding the filtering area and improving the garbage stacking efficiency in cooperation with gravity.

[0035] In order to solve the problem that traditional rainwater filtering devices mainly use a single grille structure, which can only block large-volume garbage and lack effective interception of small-particle garbage such as fine sand and leaves, resulting in frequent pipeline blockages, an implementation method is provided in this embodiment.

[0036] In one embodiment, the filtering gap of the bottom filter element 20 is smaller than that of the primary filter element 32, and the filtering gaps of the primary filter element 32 and the lateral auxiliary filter element 33 are the same.

[0037] Using the above device, by setting the filtering gaps of different filtering components, the purpose of hierarchical filtering is achieved, and the garbage interception efficiency is improved.

[0038] In order to solve the problem of further improving the filtering efficiency and the loading capacity of solid garbage, an implementation method is provided in this embodiment.

[0039] As Figure 4 shown, in one embodiment, the filtering unit 30 further includes at least two secondary filter elements 34. One end of the secondary filter element 34 is connected to one end of the primary filter element 32, and the other end is connected to the end of the bottom filter element 20. The filtering gaps of the primary filter element 32, the secondary filter element 34, and the bottom filter element 20 decrease in sequence.

[0040] Using the above device, through the combination of the primary filter element, the secondary filter element, and the bottom filter element, coarse-medium-fine three-stage interception is achieved. Moreover, by setting the secondary filter element to isolate a new garbage storage space, the garbage interception efficiency and the possibility of preventing garbage blockage are improved again.

[0041] In order to solve the problem that the filter mesh surface is prone to adhering garbage during the use of the filtering device, an implementation method is provided in this embodiment.

[0042] In one embodiment, the surfaces of the primary filter element 32, the secondary filter element 34, the lateral auxiliary filter element 33, and the bottom filter element 20 are covered with a hydrophobic coating.

[0043] Using the above device, since the hydrophobic coating has an extremely low surface energy, the intermolecular force between the garbage particles and the mesh plate is significantly weakened, making it difficult to form a firm adhesion. When rainwater flows through the hydrophobic surface, because it cannot wet the coating, it will quickly aggregate into large water droplets and carry the garbage to roll down, avoiding the garbage from sticking into blocks due to long-term immersion in water.

[0044] In order to solve the problem that it is rather troublesome to move the filtering device, an implementation method is provided in this embodiment.

[0045] As Figure 5 shown, in one embodiment, handles 40 are provided at both ends of the top support frame 31.

[0046] By using the above device, handles are provided at both ends of the top support frame, which improves the efficiency of transporting the filtering device and saves labor costs.

[0047] Next, a preferred embodiment will be combined to illustrate the content involved in the above embodiment.

[0048] As Figure 6 shown, the bottom storage member 10 is a rectangular frame welded by 304 stainless steel with dimensions of 600 mm × 400 mm × 200 mm to fit the standard municipal rain grate wellhead size. The frame is welded and formed, and a 10 mm flange is reserved at the edge of the bottom plate. The bottom filter member 20 is a 316L stainless steel woven mesh with a mesh hole diameter of 3 mm and a porosity of 50%. It is suspended 50 mm below the bottom plate by an M8 stainless steel nut-adjustable bolt, and the filtering gap is adjustable, forming an adjustable garbage storage space. The filtering unit 30 is composed of a top support frame 31, a primary filtering member 32, a lateral auxiliary filtering member 33, and a secondary filtering member 34. The top support frame 31 is made of 6061 aluminum alloy frame, and lifting handles 40 with rubber anti-slip sleeves are welded at both ends. Two primary filtering members 32 made of PP polypropylene, nylon, or stainless steel, with a pore diameter of 15 mm, are symmetrically welded at a 45° inclination angle below the top support frame 31 to form an inverted V structure. The secondary filtering member 34 is a corrugated filter screen made of PP polypropylene, nylon, or stainless steel, with a pore diameter of 8 mm. The primary filtering member 32 and the secondary filtering member 34 are connected by an oblong rod with a bolt and a matching nut at one end. The lateral auxiliary filtering member 33 is a PP polypropylene, nylon, or stainless steel punched triangular plate with a pore diameter of 15 mm, which is riveted to the side of the primary filtering member 32 to fill the gap. The secondary filtering member 34 is connected to the bottom filter member 20 by bolts. The surfaces of all filtering members are sprayed with a 50 μm polytetrafluoroethylene hydrophobic coating after degreasing and cleaning. When it rains, rainwater carrying garbage passes through the primary filtering member 32 and the lateral auxiliary filtering member 33 (mainly used to intercept large-volume garbage such as leaves and plastic bags), the secondary filtering member 34 (mainly used to intercept medium-volume garbage such as stones and debris), and the bottom filter member 20 (mainly used to intercept small-volume garbage such as sand grains) in sequence. The hydrophobic coating on the surface of each filtering member promotes the rapid passage of water flow, and the attached garbage falls off to the bottom storage member with the flushing. After each rainfall, the device is taken out by pulling the handle 40, and the bottom storage member 10 is rinsed. If there are bad weather conditions such as heavy rain, the device is cleaned according to the real-time monitoring of the well chamber water level.

[0049] As Figure 7As shown, in order to facilitate the use of a rainwater inlet garbage classification protection device provided by the present disclosure, the present disclosure also provides a construction method for the rainwater inlet garbage classification protection device, including:

[0050] S100. Lift the handle 40 and place the assembled filtering unit 30 into the bottom storage member 10;

[0051] S200. Connect the secondary filtering member 34 to the bottom filtering member 20;

[0052] S300. Lift the handle 40 and place the entire rainwater inlet garbage classification protection device into the rainwater inlet well chamber.

[0053] Clean the sludge at the bottom of the rainwater inlet well chamber, open grooves on both sides of the top wall of the well chamber, vertically hoist the device into the well chamber through the lifting handle 40 of the top support frame 31, release the lifting handle 40, and use gravity to make the device integrally embed into the top groove of the well. Tighten the bolts of the primary filtering member 32 to ensure seamless connection with the secondary filtering member 34. Finally, connect the secondary filtering member 34 to the bottom filtering member 20 through bolts.

[0054] The above has described the embodiments of the present invention in detail, but the content described is only the preferred embodiments of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
