Description

Technical Field

[0001] The utility model relates to the technical field of municipal sewage discharge, in particular to a sundries-proof rainwater grate. Background Art

[0002] In order to ensure smooth drainage of municipal roads, rainwater grates are usually installed at the sewer outlets on the road, so that the rainwater grates can serve as covers and filters, intercepting some large solid substances and debris outside the drainage system to prevent clogging of the drainage system. For rainwater grates with relatively large drainage holes, they can ensure the flow of rainwater while achieving a certain filtering effect, but this type of rainwater grate has a poor interception effect on silt and relatively small debris. When a large amount of debris accumulates, it may affect sewer drainage and cause poor drainage on the road surface to cause water accumulation. In order to ensure the filtering effect, the drainage holes of some existing rainwater grates are designed to be relatively small, which can also have a good interception effect on smaller debris, but in daily use, due to the small aperture, debris such as leaves may be intercepted on the surface of the rainwater grate, covering part of the drainage holes, affecting the discharge and collection of rainwater.

[0003] In view of this, it is necessary to design a kind of anti-debris rainwater grate to solve the above problems. Utility Model Content

[0004] The utility model aims to provide a debris-proof rainwater grate which can prevent road debris and silt from flowing into the rainwater pipe and causing the rainwater pipe to be blocked, and prevents leaves and other debris from adhering to the surface of the rainwater grate and blocking the drainage holes to affect the rainwater discharge and collection.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A debris-proof rainwater grate, comprising:

[0007] A filter box, wherein the top of the filter box is open and a plurality of water-permeable holes are provided on the filter box;

[0008] A cover plate is detachably arranged on the top of the filter box, and a plurality of drainage holes are arranged on the cover plate;

[0009] A vertical pole is arranged inside the filter box;

[0010] The balance plate is connected to the vertical pole in the middle part, and water buckets are connected to both ends of the balance plate, so that the vertical pole, the balance plate and the water bucket together form a flushing structure for flushing the cover plate.

[0011] As a further improvement of the present invention, the diameter of the water permeable hole is smaller than the diameter of the drainage hole.

[0012] As a further improvement of the utility model, the side walls and the bottom of the filter box are both provided with water permeable holes.

[0013] As a further improvement of the present invention, the filter box includes a first frame, a second frame that can move up and down relative to the first frame, and a fixing member for fixing the relative position of the first frame and the second frame. The first frame and the second frame together form a box structure with a top opening.

[0014] As a further improvement of the utility model, the vertical rod includes a fixed part arranged at the bottom of the filter box and a movable part that can move up and down relative to the fixed part.

[0015] As a further improvement of the present invention, the balancing plate is arranged on the moving part.

[0016] As a further improvement of the present invention, the cover plate is snap-connected with the filter box.

[0017] As a further improvement of the utility model, the cover plate is provided with a plurality of mounting holes penetrating from top to bottom.

[0018] As a further improvement of the utility model, an elastic limiter is arranged at the top of the filter box corresponding to the mounting hole, so that in the contracted state, the size of the elastic limiter is smaller than the diameter of the mounting hole, and in the freely extended state, the size of the elastic limiter is larger than the diameter of the mounting hole.

[0019] As a further improvement of the utility model, the elastic limiting member is connected to the top of the filter box via a vertical rod.

[0020] The beneficial effects of the utility model are:

[0021] 1. The utility model arranges a filter box under the cover plate so that rainwater is filtered by the cover plate and the filter box in turn before flowing into the rainwater pipe, which can prevent road debris and silt from flowing into the rainwater pipe and causing blockage of the rainwater pipe; at the same time, a flushing structure is arranged inside the filter box so that part of the rainwater flowing into the filter box is accumulated in the water accumulation barrel, and the lever principle is used to make the water accumulation barrels on both sides move up and down in turn with the accumulation of rainwater. When the water accumulation barrel moves upward to the cover plate, the rainwater in the barrel is sprinkled onto the back of the cover plate, and the cover plate can be reversely flushed with rainwater, which prevents leaves and other debris from sticking to the surface of the cover plate to block the drainage holes and affect the discharge and collection of rainwater.

[0022] 2. The anti-debris rainwater grate of the utility model has a simple structure, can effectively prevent debris, mud and sand from entering the rainwater pipe, extend the service life of the underground drainage system, and reduce the later maintenance cost of the underground pipe network.

[0032] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] It should also be noted that, in order to avoid obscuring the present invention due to unnecessary details, only structures and / or processing steps closely related to the scheme of the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0034] In addition, it should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0035] See also Figure 1-Figure 2 As shown, the utility model provides a debris-proof rainwater grate, comprising:

[0036] A filter box, the top of which is open and has a plurality of water-permeable holes 24;

[0037] A cover plate 10 is detachably arranged on the top of the filter box, and a plurality of drainage holes 11 are arranged on the cover plate 10;

[0038] A vertical pole is arranged inside the filter box;

[0039] The balance plate 41 has a middle portion connected to the vertical pole, and two ends of the balance plate 41 are respectively connected to water buckets 42 , so that the vertical pole, the balance plate 41 and the water bucket 42 together form a flushing structure for flushing the cover plate 10 .

[0040] Specifically, the diameter of the water-permeable hole 24 is smaller than the diameter of the drainage hole 11, and the side wall and the bottom of the filter box are both provided with water-permeable holes 24, so that rainwater flows into the filter box after the initial filtration by the cover plate 10, and flows into the rainwater pipe after the secondary filtration by the filter box. The initial filtration by the cover plate 10 can intercept large solid matter and debris outside the drainage system, and the secondary filtration by the filter box can intercept relatively small debris and silt in the filter box, avoiding the flow of road debris and silt into the rainwater pipe and causing the rainwater pipe to be blocked. The double filtration structure design of the cover plate 10 and the filter box can ensure the rainwater circulation efficiency while avoiding the blockage of the rainwater pipe caused by debris and silt, effectively extending the service life of the underground drainage system and reducing the later maintenance cost of the underground pipe network.

[0041] Specifically, the cover plate 10 is connected with the filter box by snapping. For example, a plurality of mounting holes 12 are provided around the cover plate 10 and penetrate from top to bottom; an elastic stopper 50 is provided at the top of the filter box corresponding to the mounting hole 12, so that in the contracted state, the size of the elastic stopper 50 is smaller than the diameter of the mounting hole 12, and in the freely extended state, the size of the elastic stopper 50 is larger than the diameter of the mounting hole 12. The elastic stopper 50 is connected to the top of the filter box through a vertical rod 60 ( Figure 3 ), the height of the vertical rod 60 is greater than the thickness of the cover plate 10, so that under the action of external force, the elastic limit member 50 passes through the mounting hole 12 in a contracted state. When the external force is removed, the elastic limit member 50 is in a freely extended state and is engaged above the mounting hole 12, so that the cover plate 10 and the filter box remain relatively fixed.

[0042] For example, Figure 4As shown, the elastic stopper 50 includes a horizontal rod 51 with a hollow interior, a vertical plate 52 is provided in the middle of the horizontal rod 51, and horizontal telescopic rods 54 are connected to both sides of the vertical plate 52 through springs 53; under the action of external force, the two horizontal telescopic rods 54 are retracted into the interior of the horizontal rod 51, so that the elastic stopper 50 can pass through the mounting hole 12, and the external force is removed. Under the restoring force of the spring 53, the two horizontal telescopic rods 54 partially move to the outside of the horizontal rod 51, so that the elastic stopper 50 can be engaged above the mounting hole 12, so as to fix the cover plate 10 and the filter box. Through the detachable design of the cover plate 10 and the filter box, it is convenient to disassemble the cover plate 10 and the filter box as needed to clean the intercepted objects inside the filter box.

[0043] For example, Figure 1 , Figure 5 and Figure 6 As shown, the filter box includes a first frame 21, a second frame 22 that can move up and down relative to the first frame 21, and a fixing member 23 for fixing the relative position of the first frame 21 and the second frame 22. The first frame 21 and the second frame 22 together form a box structure with an open top. The side wall of the first frame 21 is provided with a groove 212 that opens upward, and the second frame 22 is located in the groove 212 and can move up and down in the vertical direction; the side wall of the first frame 21 is provided with a plurality of first through holes 211 at intervals along the vertical direction, and the bottom of the second frame 22 is provided with a second through hole 221. After adjusting the height of the second frame 22 relative to the first frame 21 as needed, the fixing member 23 is passed through the first through hole 211 and the second through hole 221 in sequence to achieve the fixing of the first frame 21 and the second frame 22. In this embodiment, the fixing member 23 is a bolt. By adjusting the height of the first frame 21 relative to the second frame 22, the capacity of the filter box can be adjusted to meet the filtering needs of different rainfalls, that is, in seasons with large rainfall, the rainwater filtering effect can be ensured by increasing the capacity of the filter box.

[0044] The bottom and side walls of the first frame 21 and the side walls of the second frame 22 are provided with a plurality of water holes 24, so that when debris or silt accumulates at the bottom of the first frame 21 and affects the efficiency of rainwater passing through the bottom, the rainwater can flow along the water holes 24 on the side walls to the rainwater pipe, thereby ensuring the circulation effect of rainwater.

[0045] Specifically, Figure 7As shown, the vertical pole includes a fixed portion arranged at the bottom of the first frame 21 and a movable portion that can move up and down relative to the fixed portion. Exemplarily, the fixed portion is a support tube 31 with an opening at the top, and the movable portion is an adjustment rod 32 that penetrates into the support tube 31 from the top opening of the support tube 31. The adjustment rod 32 is provided with a plurality of adjustment holes 321 spaced apart in the vertical direction, and the upper part of the support tube 31 is correspondingly provided with an insertion hole 311. After adjusting the height of the adjustment rod 32 relative to the support tube 31 as needed, the bolt is inserted into the adjustment hole 321 through the insertion hole 311, so that the adjustment rod 32 can be kept fixed relative to the support tube 31.

[0046] The balance plate 41 is arranged on the adjustment rod 32. When the capacity of the filter box increases, by increasing the height of the adjustment rod 32 relative to the support tube 31, the vertical spacing between the balance plate 41 and the cover plate 10 can always be kept relatively stable, so that the water bucket 42 can be quickly moved upward to the back of the cover plate 10 through the lever principle, and the rainwater in the bucket can be sprinkled on the back of the cover plate 10, and the cover plate 10 can be reversely flushed by the rainwater, so as to avoid leaves and other debris attached to the surface of the cover plate 10 to block the drainage hole 11 and affect the discharge and collection of rainwater. The synchronous adjustment of the filter box capacity and the height of the vertical pole can avoid the vertical spacing between the water bucket 42 and the cover plate 10 is too large when the filter box capacity increases, which affects the flushing effect of the rainwater in the water bucket 42 on the cover plate 10. The size of the water bucket 42 can be adjusted according to the actual situation, so that when the water bucket 42 on one side moves quickly upward to the cover plate 10, the rainwater in the bucket can be sprinkled on the cover plate 10 to flush the cover plate 10.

[0047] The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model.
