Description

Technical Field

[0001] The present invention relates to the technical field of municipal drainage purification, and in particular to a drainage purification treatment device for a municipal sewage pipe network. Background Art

[0002] Rainwater drainage is a crucial component of urban municipal drainage systems, primarily achieved through rainwater purification and drainage systems. These systems are responsible for transporting collected rainwater to urban or natural water bodies, such as rivers, lakes, or oceans, to prevent urban waterlogging and flooding.

[0003] Application No. 202411697426.7 discloses a municipal sewage network drainage purification and treatment device, which is used to control the movement of the interception grid frame to the outside or inside of the drainage pipe according to the amount of rainfall, so that the drainage outlets of urban roads are not easily blocked in heavy rain weather, thereby improving the purification, interception and drainage efficiency of garbage at the drainage outlets and reducing the adverse effects on urban drainage and traffic.

[0004] However, in order to achieve the anti-blocking effect, this solution requires moving the intercepting grille outward, and people may not pay attention to the road conditions while walking, especially in heavy rain, which may cause collisions and falls. Summary of the Invention

[0005] The present invention discloses a drainage purification treatment device for a municipal sewage pipe network, which aims to solve the technical problem that in order to achieve an anti-blocking effect, the interception grid frame needs to be moved outward, and people may not pay attention to the road conditions under their feet when walking, especially in a heavy rain environment, which may cause collisions and falls.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: A municipal sewage pipe network drainage purification treatment device includes a support silo and a sealing plate movably connected to the top of the support silo, wherein the support silo is buried underground, and further includes: a primary filtering mechanism fixedly connected to an inner wall of one side of the support silo; a flow meter fixedly mounted on an outer wall of one side of the primary filtering mechanism; a secondary filtering mechanism located between the support silo and the sealing plate; and an algae inhibition mechanism connected to the sealing plate. The primary filtering mechanism includes: a support frame, which is fixedly connected to the inner wall of one side of the support bin body, and the flow meter is fixedly installed on the outer wall of one side of the support frame; a plurality of railings 1, which are equidistantly fixedly connected to the inner walls of the opposite sides of the support frame; a plurality of waist-shaped grooves, which are equidistantly set through the inner walls of the opposite sides of the support frame; a railing 2, which is movably inserted into the plurality of waist-shaped grooves, and the plurality of railings 2 are staggered with the plurality of railings 1, and the outer walls of the same side of each railing 2 and railing 1 are respectively fixedly connected with a plurality of needles 1; two side support plates 1, which are movably fitted to the inner walls of the two sides of the support frame and fixedly connected to the two ends of the plurality of railings 2; a side support plate 2, which is fixedly connected to the outer wall of one side of one of the side support plates 1; an electric telescopic rod, which is fixedly connected to the inner wall of the bottom end of the support frame, and its output end is fixedly connected to the outer wall of the bottom end of the side support plate 2; The secondary filtering mechanism includes a grid plate, which is obliquely arranged in the supporting chamber; The inner wall of the support bin is fixedly connected to the limiting frame, and the bottom end of the sealing plate is movably fitted to the top end of the limiting frame; The first-level filtering mechanism also includes: multiple sliders, which are fixedly connected to the outer wall of one side of the other side support plate; multiple sliding rods, which are fixedly connected to the top and bottom inner walls of the support frame, and the multiple sliders are movably connected to the sliding rods at the same time; multiple water leakage holes are set through the inner wall of one side of the support frame.

[0007] By providing a primary filtering mechanism and a secondary filtering mechanism, when the flow meter detects that the sewage flow rate increases, the electric telescopic rod drives the second railing to move horizontally, thereby expanding the cross-section of the water supply flow, so that the garbage can smoothly pass through the support frame and enter the interior of the support bin, and then the garbage is filtered by the obliquely arranged grid plate, which can effectively avoid blockage caused by garbage accumulation. At the same time, the structure does not need to extend outward and will not hinder road traffic. At the same time, based on the setting of the needle one and its repeated movement, the adhered plastic bag and the unfolded garbage can be separated from the second railing and the first railing, further reducing the possibility of blockage.

[0008] In a preferred embodiment, the algae inhibition mechanism includes: a special-shaped groove provided on the inner wall of the bottom end of the sealing plate, and the inner wall of the special-shaped groove is respectively provided with a plurality of connection holes; a second horizontal plate provided in the special-shaped groove, and the outer wall of one side of the second horizontal plate is fixedly connected to two inclined plates; The algae suppression mechanism further includes: a plurality of support shafts fixedly connected to the connection between the second horizontal plate and the inclined plate, and the plurality of support shafts are correspondingly located in the plurality of connection holes; a plurality of torsion springs respectively sleeved on the outside of the plurality of support shafts, with one end of each torsion spring fixedly connected to the outer wall of the support shaft and the other end fixedly connected to the inner wall of the connection hole; The algae inhibition mechanism further comprises: two glass frames respectively fixedly embedded in the two inclined plates; two ultraviolet lamps respectively fixedly installed in the two glass frames, and the ultraviolet light can pass through the glass frames.

[0009] By providing an algae inhibition mechanism, intermittent irradiation of the ultraviolet lamp can be achieved through manual timing, and the ultraviolet light can cover the surface of the first and second railings and the grating, thereby effectively inhibiting the formation of algae, avoiding the blockage caused by algae and the difficulty in cleaning, and ensuring the filtering effect under long-term use. In addition, when the closing plate is lifted, the inclined plate is immersed in the special-shaped groove, which can provide protection for the glass frame and the ultraviolet lamp. When the closing plate is covered, the inclined plate extends obliquely into the supporting chamber to ensure complete coverage of the ultraviolet light.

[0010] In a preferred embodiment, the secondary filtering mechanism further comprises: two chutes, symmetrically and obliquely fixedly connected to the inner walls of the supporting chamber on opposite sides, and the two sides of the grid plate are movably connected to the chutes; a second needle, fixedly connected to the outer wall of one side of the grid plate and close to the bottom thereof; a first horizontal plate, fixedly connected to the top outer wall of the grid plate, and a first handle fixedly connected to the outer wall of one side of the horizontal plate; The secondary filtering mechanism further includes: a square through-groove, which is provided through the horizontal plate; a hinge hole, which is symmetrically provided on the inner walls of the supporting chamber on opposite sides, and the two sides of the sealing plate are hingedly connected to the hinge hole by a hinge rod; the top of the supporting chamber is provided with an opening, and the sealing plate covers the top of the opening; a square groove, which is provided on the inner wall of the bottom end of the sealing plate; The secondary filtering mechanism also includes: two hinge holes, symmetrically arranged on the inner walls of the opposite sides of the square groove; a hanging plate, passing through the square through groove, and the two sides of the hanging plate are respectively hinged to the hinge hole two by two hinge rods, and a handle two is fixedly connected to the outer wall of one side of the hanging plate; an oblique angle one, arranged on the inner wall of the top end of the supporting bin body, and one side of the sealing plate is movably fitted on the oblique angle one.

[0011] By setting up a two-level filtering mechanism, the grating is set at an angle. In order to ensure sufficient filtering surface, the depth of the grating must also be sufficient, which makes it difficult to clean up the garbage on the surface of the grating after heavy rain. The grating can be lifted by pulling the handle one, which is convenient for cleaners to clean up the garbage accumulated on the surface of the grating. At the same time, the sealing plate is supported at an angle. After opening the hanging plate by the handle two, the hanging plate can be passed through the square groove to support the grating, which is more convenient for cleaners to deal with the accumulated garbage.

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] The municipal sewage network drainage purification treatment device disclosed in the present invention is mainly used in the scenario of municipal sewage network drainage purification.

[0021] Reference Figure 1 and Figure 2 A municipal sewage pipe network drainage purification treatment device includes a support silo 4 and a sealing plate 3 movably connected to the top of the support silo 4, the support silo 4 is buried underground, and further includes: The primary filtering mechanism 2 is fixedly connected to the inner wall of one side of the supporting bin body 4; The flow meter 1 is fixedly mounted on one side outer wall of the first-stage filtering mechanism 2; The secondary filtering mechanism 6 is located on the supporting chamber 4 and the sealing plate 3; Algae inhibition mechanism 7, connected to the sealing plate 3; The first-level filtering mechanism 2 includes: The support frame 201 is fixedly connected to the inner wall of the support chamber 4, and the flow meter 1 is fixedly installed on the outer wall of the support frame 201; A plurality of railings 202 are fixedly connected to the inner walls of the supporting frame 201 at equal intervals; A plurality of waist-shaped through grooves 207 are equidistantly provided through the inner walls of the support frame 201 on opposite sides; The second railing 205 is movably inserted into the plurality of waist-shaped slots 207, and the plurality of second railings 205 are staggered with the plurality of first railings 202. The outer wall of each second railing 205 and the same side of the first railing 202 is fixedly connected to a plurality of first needles 211. The two side support plates 204 are movably attached to the inner walls of the support frame 201 and fixedly connected to the two ends of the plurality of railings 205; The second side support plate 209 is fixedly connected to one outer wall of one side support plate 1 204; The electric telescopic rod 210 is fixedly connected to the inner wall of the bottom end of the support frame 201, and its output end is fixedly connected to the outer wall of the bottom end of the second side support plate 209. When the flow meter 1 detects that the sewage flow rate increases, the electric telescopic rod 210 drives the multiple second railings 205 to move horizontally in the waist-shaped groove 207, so that the second railings 205 fit on one side of the first railing 202, thereby expanding the cross-section of the water supply flow, allowing the garbage to smoothly pass through the support frame 201 and enter the interior of the support bin 4; The secondary filtering mechanism 6 includes a grating 606, which is obliquely arranged in the supporting bin body 4. The garbage entering the interior is then filtered by the obliquely arranged grating 606. Based on the setting of the grating 606, the oblique setting and the expansion of the filtering area can effectively avoid blockage caused by garbage accumulation. At the same time, the structure does not need to extend outward and will not hinder road traffic. At the same time, based on the setting of the needle 1 211, when it is detected that the sewage flow becomes larger and lasts for a long time, while changing the filtering spacing, the electric telescopic rod 210 is also intermittently controlled to reciprocate to avoid large garbage such as plastic bags from covering the outside of the railing 2 205 and the railing 1 202 after the spacing is expanded. The needle 1 211 passes through the plastic bag, and through the reciprocating motion of the railing 205, the plastic bag can be punctured and separated from the railing 2 205 and the railing 1 202, further reducing the possibility of blockage.

[0022] Reference Figure 2 In a preferred embodiment, the inner wall of the support silo 4 is fixedly connected to the limiting frame 5, and the bottom end of the sealing plate 3 is movably attached to the top end of the limiting frame 5; The first-level filtering mechanism 2 also includes: Multiple sliders 203 are fixedly connected to one side outer wall of the other side support plate 1 204; Multiple sliding rods 206 are fixedly connected to the top and bottom inner walls of the support frame 201, and multiple sliders 203 are simultaneously movably connected to the sliding rods 206. The sliders 203 move on the sliding rods 206 to assist the multiple railings 205 in stable translation up and down, ensuring that the side support plate 204 can be movably fitted to the inner wall of the support frame 201 during movement; A plurality of leakage holes 208 are provided through the inner wall of one side of the support frame 201. The provision of the leakage holes 208 allows the sewage entering the support frame 201 to be discharged smoothly, thereby preventing the sewage from continuously accumulating in the support frame 201 and causing corrosion.

[0023] Reference Figure 3 and Figure 4 In a preferred embodiment, the secondary filtering mechanism 6 further comprises: Two chute grooves 601 are symmetrically and obliquely fixedly connected to the inner walls of the support chamber 4 on opposite sides, and the two sides of the grid plate 606 are movably connected to the chute grooves 601 respectively; The second needle 608 is fixedly connected to the outer wall of one side of the grid plate 606 and is close to its bottom position. The grid plate 606 is set obliquely. In order to ensure sufficient filtering surface, the depth of the grid plate 606 must also be sufficient. As a result, garbage on the surface of the grid plate 606 is not easy to clean after heavy rain. The setting of the second needle 608 can limit the garbage at a low position to prevent it from sliding, and use the low-lying garbage as a bottom blockage to keep the upper garbage on the grid plate 606. Based on the setting of the chute 601, the grid plate 606 can be pulled obliquely by the handle 1 607 to lift the grid plate 606, making it easier for cleaners to clean garbage accumulated on the surface of the grid plate 606. The horizontal plate 1 604 is fixedly connected to the top outer wall of the grid plate 606 , and a handle 1 607 is fixedly connected to one side outer wall of the horizontal plate 1 604 .

[0024] Reference Figure 3 and Figure 4 In a preferred embodiment, the secondary filtering mechanism 6 further comprises: A square through slot 605 is provided through the horizontal plate 1 604; Hinge holes 602 are symmetrically arranged on opposite inner walls of the support chamber 4, and both sides of the sealing plate 3 are hingedly connected to the hinge holes 602 via hinge rods 613. The top of the support chamber 4 is provided with an opening, and the sealing plate 3 covers the top of the opening. The square groove 610 is provided on the inner wall of the bottom end of the sealing plate 3 .

[0025] Reference Figure 3 and Figure 4 In a preferred embodiment, the secondary filtering mechanism 6 further comprises: Hinge holes 609 are symmetrically arranged on the inner walls of the square groove 610 on two opposite sides; The hanging plate 612 passes through the square through-slot 605, and both sides of the hanging plate 612 are hinged to the hinge hole 609 via the hinge rod 611, and the outer wall of one side of the hanging plate 612 is fixedly connected to the handle 614; Bevel 1 603 is arranged on the inner wall of the top end of the support bin body 4, and one side of the sealing plate 3 is movably fitted on bevel 1 603. At the same time, the sealing plate 3 can ensure support at a certain angle under the limiting action of bevel 1 603. After opening the hanging plate 612 through handle 2 614, the hanging plate 612 can pass through the square through-groove 605 to support the grid plate 606, which is more convenient for cleaners to handle accumulated garbage.

[0026] Reference Figure 5 In a preferred embodiment, the algae suppression mechanism 7 comprises: The special-shaped groove 701 is provided on the inner wall of the bottom end of the sealing plate 3, and the inner wall of the special-shaped groove 701 is provided with a plurality of connecting holes 702; The second transverse plate 703 is disposed in the special-shaped groove 701 , and two inclined plates 704 are fixedly connected to an outer wall of one side of the second transverse plate 703 .

[0027] Reference Figure 5 In a preferred embodiment, the algae inhibition mechanism 7 further comprises: A plurality of support shafts 708 are fixedly connected to the connection between the second horizontal plate 703 and the inclined plate 704, and the plurality of support shafts 708 are correspondingly located in the plurality of connection holes 702; The plurality of torsion springs 707 are respectively sleeved on the outside of the plurality of support shafts 708 , with one end of the torsion springs being fixedly connected to the outer wall of the support shaft 708 and the other end being fixedly connected to the inner wall of the connection hole 702 .

[0028] Reference Figure 5 In a preferred embodiment, the algae inhibition mechanism 7 further comprises: Two glass frames 705 are fixedly embedded in the two inclined plates 704 respectively; Two ultraviolet lamps 706 are fixedly installed in two glass frames 705 respectively, and the ultraviolet light can pass through the glass frames 705. Intermittent irradiation of the ultraviolet lamp 706 can be achieved through manual timing, so that the ultraviolet light can cover the surface of the railing 202, the railing 205 and the grid 606, thereby effectively inhibiting the formation of algae, preventing algae in sewage in a humid environment from adhering to the railing 202, the railing 205 and the grid 606, causing algae to grow everywhere, causing blockage and difficulty in cleaning, thereby ensuring the filtering effect under long-term use. In addition, under the action of the torsion spring 707, When the closing plate 3 is lifted, the inclined plate 704 rotates about the support shaft 708 and sinks into the special-shaped groove 701, providing protection for the glass frame 705 and the ultraviolet lamp 706 to avoid damage to the ultraviolet lamp 706 caused by accidental touching when cleaning the grid 606. When the closing plate 3 is covered, one end of the second horizontal plate 703 is squeezed on the limit frame 5, so that the second horizontal plate 703 moves to a horizontal state. At this time, the inclined plate 704 is separated from the special-shaped groove 701 and extends obliquely into the supporting bin body 4, which can ensure that the two sides of the ultraviolet lamp 706 are respectively facing the railing 1 202, the railing 205 and the grid 606, thereby ensuring complete coverage of the ultraviolet light.

[0029] Working principle: When the flow meter 1 detects that the sewage flow rate becomes larger, the electric telescopic rod 210 drives the multiple railings 205 to move horizontally in the waist-shaped groove 207, so that the railings 205 fit on one side of the railing 1 202, thereby expanding the cross-section of the water supply flow, so that the garbage can smoothly pass through the support frame 201 and enter the support bin 4, and then the obliquely arranged grid plate 606 filters the garbage. Based on the setting of the grid plate 606, the oblique setting and the expansion of the filtering area can effectively avoid the blockage caused by garbage accumulation. At the same time, the structure does not need to be outward. At the same time, based on the setting of the needle 1 211, when it is detected that the sewage flow becomes larger and lasts for a long time, while changing the filter spacing, the electric telescopic rod 210 is also intermittently controlled to reciprocate, so as to prevent large garbage such as plastic bags from covering the outside of the railing 2 205 and the railing 1 202 after the spacing is expanded. The needle 1 211 passes through the plastic bag, and the reciprocating motion of the railing 205 can puncture the plastic bag and make the plastic bag separate from the railing 2 205 and the railing 1 202, thereby further reducing the possibility of blockage.

[0030] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
