Description

Technical Field

[0001] The utility model relates to the technical field of municipal drainage, in particular to a municipal water supply and drainage anti-blocking device. Background Art

[0002] Municipal water supply and drainage anti-clogging devices usually refer to facilities or technologies used in urban water supply and drainage systems to prevent debris accumulation and blockage in pipes. This device can effectively reduce maintenance costs and ensure the normal operation of water supply and drainage systems.

[0003] The patent with announcement number CN218454458U discloses a municipal water supply and drainage anti-blocking device. By setting up a hanging basket, garbage such as leaves can be blocked to prevent them from flowing into the drainage pipe. At the same time, by extending the push handle into the through hole of the manhole cover, the push plate can be pushed to push the garbage to both sides to prevent the accumulation of garbage from affecting the drainage of the hanging basket. This makes it convenient to clean up the garbage at the obstruction and improve the drainage efficiency. Usually, the hanging basket at the rainwater grate adopts a rectangular shape, which has a limited contact range with rainwater and has the defect of a small filtering area.

[0004] The patent with announcement number CN219508761U discloses a municipal water supply and drainage anti-blocking device. Rainwater and other water flows into the material guide filter bucket through the manhole cover. After being filtered by the material guide filter bucket, debris and the like are retained in the material guide filter bucket and fall into the collection bucket under the action of gravity. The debris is filtered by the material guide filter bucket and collected by the collection bucket, which can prevent the debris from clogging the material guide filter bucket. At the same time, the structure is simple and easy to disassemble and assemble, which is convenient for subsequent collection and processing of debris. If the hanging basket in the rainwater grate is set into a funnel shape based on the shape of the filter bucket, the filtering area of ​​the hanging basket and rainwater can be effectively increased, and the filtering efficiency can be improved. However, when the hanging basket is set into a funnel shape, the height of the hanging basket should take into account the depth of the rainwater collection well.

[0005] In addition, in the above two patents, the drainage holes are set as circular holes, and leaves and the like are easy to adhere to the surface of the drainage holes, which can easily cause the drainage holes to be blocked, resulting in a significant reduction in the filtration efficiency.

[0006] In view of this, designing a municipal water supply and drainage anti-blocking device, which contains a filtering structure with freely adjustable height to be suitable for water collection wells of different depths, and to reduce the blockage of drainage holes and improve filtration efficiency has become a technical problem that technical personnel in this field urgently need to solve. Utility Model Content

[0007] The utility model aims to provide a municipal water supply and drainage anti-blocking device to overcome the above-mentioned shortcomings.

[0008] In order to achieve the above purpose, the technical solution of the utility model is:

[0009] A municipal water supply and drainage anti-blocking device, comprising:

[0010] A well frame, wherein a plurality of stepped holes are arranged on the inner side of the well frame, and a mounting frame is integrally formed on the outer side of the well frame; and

[0012] Furthermore, a sliding hole is arranged on the bottom plate of the upper filter basket monomer, and the outer side wall of the lower filter basket monomer is slidably connected with the sliding hole of the adjacent upper filter basket monomer.

[0013] Furthermore, the upper edge of the side wall of the filter basket monomer extends toward the circumference to form a first stop edge, the topmost first stop edge is detachably connected to the stepped hole, and the first stop edge of the lower filter basket monomer abuts against the upper surface of the bottom plate of the adjacent upper filter basket monomer.

[0014] Furthermore, the bottom plate of the lower filter basket monomer extends toward the circumference to form a second stop edge, and the second stop edge of the lower filter basket monomer selectively abuts against the lower surface of the bottom plate of the adjacent upper filter basket monomer.

[0015] Furthermore, a first connecting ring and a second connecting ring are respectively installed in the uppermost filter basket monomer and the lowermost filter basket monomer, and a connecting rope is connected between the first connecting ring and the second connecting ring.

[0016] Furthermore, the drainage hole comprises:

[0017] a first drainage hole disposed on the side wall of the filter basket unit; and

[0018] A second drainage hole is arranged on the bottom plate of the filter basket unit.

[0019] Furthermore, a support frame is installed in the second drainage hole, a shielding cover is fixedly connected above the support frame, and the shielding cover is located above the second drainage hole and is gap-matched with the second drainage hole.

[0020] Furthermore, the support frame comprises:

[0021] a cross brace fixedly connected to the second drain hole; and

[0022] A support rod with a lower end fixedly connected to the cross brace, and an upper end of the support rod fixedly connected to the shielding cover.

[0023] Furthermore, the shielding cover is a spherical body, the concave surface of the shielding cover faces the second drainage hole, and the shielding cover is arranged above the second drainage hole, and the lower edge of the shielding cover is larger than the diameter of the second drainage hole.

[0024] Furthermore, filtering holes are arranged on the rainwater grate.

[0025] Compared with the prior art, the utility model has at least the following advantages:

[0026] The filter basket in the utility model comprises a plurality of filter basket monomers, and the filter basket monomers are slidably connected to each other. The filter basket monomers naturally droop in the water collection well to form a larger contact area with rainwater, thereby effectively increasing the filter area of ​​the filter basket and improving the filtering efficiency.

[0027] Since the filter basket unit can droop naturally, the total height of the filter basket unit is adjustable, so that it can be applied to water collection wells of different depths and has a wider range of applications.

[0028] In the process of filtering rainwater, the utility model provides drainage holes on the side walls and the bottom plate of the filter basket, and garbage such as fallen leaves gradually accumulates on the bottom plate of the filter basket unit. Due to gravity and rainwater scouring, the drainage holes on the side walls of the filter basket unit are usually difficult to be blocked, and due to the connection method between the filter basket units, more garbage such as fallen leaves can be collected, thereby effectively preventing the occurrence of blockage.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0038] Reference Figure 1-2 The utility model provides a municipal water supply and drainage anti-blocking device, including a well frame 3, a filter basket and a rainwater grate 1. A multi-step hole is designed on the inner side of the well frame 3, and a mounting frame is integrally formed on the outer side. The filter basket and the rainwater grate 1 are detachably connected to the step hole, the filter basket is located below the rainwater grate 1, and the mounting frame is used to be buried in the road structure layer. Among them, the filter basket is composed of a plurality of filter basket monomers 4 arranged in sequence along the vertical direction, and a sliding connection is adopted between adjacent filter basket monomers 4. Observing from top to bottom, the projection size of the plurality of filter basket monomers 4 along the vertical direction gradually decreases. At the same time, each filter basket monomer 4 is provided with a drainage hole, and the drainage hole is arranged on the side wall and the bottom plate of the filter basket monomer 4, which can achieve a filtering effect on garbage such as fallen leaves.

[0039] In order to further optimize the drainage effect, filtering holes 2 are arranged on the rainwater grate 1 to achieve primary filtering of garbage such as fallen leaves.

[0040] In a further optimized design, a sliding hole 5 is arranged on the bottom plate of the upper filter basket monomer 4, so that the outer side wall of the lower filter basket monomer 4 can be slidably connected with the sliding hole 5 of the adjacent upper filter basket monomer 4. The upper edge of the side wall of the filter basket monomer 4 extends to the circumferential side to form a first stop edge 6, and the uppermost first stop edge 6 is detachably connected to the stepped hole, while the first stop edge 6 of the lower filter basket monomer 4 abuts against the upper surface of the bottom plate of the adjacent upper filter basket monomer 4.

[0041] In order to improve the connection stability, the bottom plate of the lower filter basket monomer 4 extends to the circumferential side to form a second stop edge 7, and the second stop edge 7 can selectively abut against the lower surface of the bottom plate of the adjacent upper filter basket monomer 4. In addition, the first connecting ring 8 and the second connecting ring 9 are respectively installed in the uppermost and lowermost filter basket monomers 4, and the two are connected by a connecting rope 10. In a specific embodiment of the utility model, the connecting rope 10 is a steel wire rope.

[0042] When in use, garbage such as fallen leaves enters the filter basket monomer 4 after being filtered through the filter hole 2, and then flows into the rainwater collection well after being filtered by the filter basket monomer 4. The filter basket monomers 4 are connected by sliding, and can naturally droop in the rainwater collection well by their own gravity, and can be applied to collection wells of different depths. The naturally drooping filter basket monomer 4 can increase the contact area with rainwater, increase the filtration area of ​​the filter basket monomer 4, and improve the filtration efficiency. In addition, during storage or transportation, the filter basket monomers 4 can be nested with each other, reducing the storage space.

[0043] After a period of use, fallen leaves and other garbage accumulate above the bottom plate of the filter basket monomer 4. The bottom filter basket monomer 4 is lifted up in turn by the connecting rope 10, and the garbage in the filter basket monomer 4 is cleaned by a cleaning or dust suction device. The filter basket cleaning process can be achieved without removing the entire filter basket. In addition, when a single filter basket monomer 4 is damaged and disconnected from other filter basket monomers 4, the connecting rope 10 can also ensure that the filter basket monomer 4 falls to the bottom of the water collection well, thereby avoiding the phenomenon of clogging the water collection well outlet.

[0044] Reference Figure 3-5 In terms of the drainage system, the drainage holes include a first drainage hole 11 arranged on the side wall of the filter basket unit 4 and a second drainage hole 12 arranged on the bottom plate of the filter basket unit 4. A support frame is installed in the second drainage hole 12, and a shielding cover 15 is fixedly connected above the support frame to achieve clearance fit with the second drainage hole 12.

[0045] The support frame mainly consists of two parts: one is a cross brace 13 fixedly connected to the second drain hole 12; the other is a support rod 14 fixedly connected to the cross brace 13 at the lower end, and fixedly connected to the shielding cover 15 at the upper end. The shielding cover 15 is designed as a spherical body, with its concave surface facing the second drain hole 12 and covering it. The diameter of the lower edge of the shielding cover 15 is larger than the second drain hole 12. Usually, the size of the shielding cover 15 is larger than the area of ​​the fallen leaves. When the fallen leaves fall on the shielding cover, the shielding cover 15 can achieve the effect of lifting the fallen leaves, thereby preventing them from sticking to the second drain hole 12. Since the shielding cover 15 and the second drain hole 12 are clearance-matched, there is a gap between the two, and rainwater can pass through the gap between the two. Pass through the second drain hole 12.

[0046] In the present invention, since the cross brace 13 is disposed in the second drainage hole 12 , the aperture of the second drainage hole 12 is usually larger than the aperture of the first drainage hole 11 , so as to improve the drainage efficiency of the second drainage hole 12 .

[0047] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0048] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
