Description

Technical Field

[0001] The utility model relates to the technical field of concealed culverts, in particular to a concealed culvert sewage interception device. Background Art

[0002] At present, the following problems exist in culverts: 1. Sewage is secretly discharged into culverts by buildings above ground; 2. Culverts are in a dark, enclosed space for a long time, which is very easy to produce anaerobic odor and silt deposition. Regarding the situation where sewage is secretly discharged into culverts by buildings above ground, the sewage above ground contains various impurities, such as silt, masonry, foam, etc. After being discharged into the culvert, it will be directly discharged into the river, causing river pollution or accumulation in the culvert. The accumulation of various impurities will cause anaerobic odor and block the sewage outlet.

[0003] There are currently two ways to deal with the accumulation of impurities in the culvert:

[0004] 1. Manual cleaning is labor-intensive and time-consuming due to the harsh environment in the culvert and the scattered impurities;

[0005] 2. Automatic cleaning by robots is costly and burdensome. Summary of the invention

[0006] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by this patent application is how to provide a culvert sewage interception device that can filter and separate impurities and collect impurities for later treatment.

[0007] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0008] A culvert sewage interception device, wherein the culvert side wall has a plurality of drainage pipes arranged at intervals, and the end of the drainage pipe located in the culvert is the drainage end;

[0009] A filtering structure is provided between the drainage end of the drainage pipe and the extension pipe;

[0010] The drainage end of the drainage pipe is connected downwardly to a sewage pipe, and an electric butterfly valve is installed on the sewage pipe;

[0011] A collecting frame is fixedly installed in the culvert, and the collecting frame is arranged below the sewage pipe. The lower parts of both ends of the collecting frame penetrate through, and a scraper assembly is installed in the collecting frame; the end of the extension pipe is located outside the collecting frame.

[0012] In this way, sewage enters the culvert through the drainage pipe, reaches the extension pipe after being filtered by the filter structure, and is discharged from the extension pipe. Since the end of the extension pipe is located outside the collection frame, the sewage is discharged to the outside of the collection frame and then flows out through the culvert. The impurities intercepted by the filter structure reach the sewage pipe, and the electric butterfly valve is opened. The impurities fall into the collection frame under their own gravity. The reciprocating movement of the scraper assembly scrapes the impurities to both sides of the collection frame. When cleaning, the operator only needs to clean the impurities on both sides of the collection frame without entering the culvert, which saves time and effort and is easy to operate.

[0013] Among them, the scraper assembly includes a scraper, two screws are installed in the collection frame through bearings, nut blocks are threadedly connected to the screws, the nut blocks are fixedly connected to the scraper, the ends of the screws pass through the collection frame and are fixedly connected to the output shaft of the servo motor, and the servo motor is fixedly installed on the collection frame.

[0014] Wherein, the filtering structure comprises a filtering bracket, on which a filtering net is fixedly mounted, and the filtering bracket is connected to the drainage end and the extension pipe of the drainage pipe via a flange.

[0015] Wherein, sealing pads are arranged between the two sides of the filter bracket and the drainage end and the extension pipe of the drainage pipe.

[0016] Wherein, both sides of the scraper are inclined surfaces inclined outwards.

[0017] In summary, the culvert sewage interception device has the advantages of being able to filter and separate impurities and collect impurities for later processing. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present invention is further described in detail below in conjunction with the accompanying drawings. In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional words such as "upper, lower" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description. Unless otherwise stated, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0023] like Figure 1-4 As shown, a culvert sewage interception device, the side wall of the culvert 1 has a plurality of drainage pipes 2 arranged at intervals, and the end of the drainage pipe located in the culvert is the drainage end;

[0024] A filtering structure is provided between the drainage end of the drainage pipe and the extension pipe 3;

[0025] The drainage end of the drainage pipe is connected downward to a sewage pipe 6, and an electric butterfly valve 4 is installed on the sewage pipe;

[0026] A collecting frame 5 is fixedly installed in the culvert. The collecting frame is arranged below the sewage pipe. The lower parts of both ends of the collecting frame penetrate through. A scraper assembly is installed in the collecting frame. The end of the extension pipe is located outside the collecting frame.

[0027] In this way, sewage enters the culvert through the drainage pipe, reaches the extension pipe after being filtered by the filter structure, and is discharged from the extension pipe. Since the end of the extension pipe is located outside the collection frame, the sewage is discharged to the outside of the collection frame and then flows out through the culvert. The impurities intercepted by the filter structure reach the sewage pipe, and the electric butterfly valve is opened. The impurities fall into the collection frame under their own gravity. The reciprocating movement of the scraper assembly scrapes the impurities to both sides of the collection frame. When cleaning, the operator only needs to clean the impurities on both sides of the collection frame without entering the culvert, which saves time and effort and is easy to operate.

[0028] Specifically, the filtering structure is arranged on one side above the sewage pipe, and the filtered impurities directly fall into the sewage pipe for easy discharge.

[0029] During implementation, the scraper assembly includes a scraper 7, two screws 8 are installed in the collection frame through bearings, and a nut block is threadedly connected to the screw. The nut block is fixedly connected to the scraper, and the end of the screw passes through the collection frame and is fixedly connected to the output shaft of the servo motor 9, and the servo motor is fixedly installed on the collection frame. The servo motor drives the screw to rotate, and drives the scraper to move through the nut block, and the scraper scrapes the impurities.

[0030] During implementation, the filtering structure includes a filtering support 10, on which a filtering screen 11 is fixedly mounted, and the filtering support is connected to the drainage end and the extension pipe of the drainage pipe via a flange. The filtering screen blocks impurities and separates the impurities from water.

[0031] During implementation, sealing pads are arranged between the two sides of the filter bracket and the drainage end and the extension pipe of the drainage pipe to avoid water leakage.

[0032] During implementation, both sides of the scraper are inclined surfaces arranged outwardly, thereby improving the strength of the scraper.

[0033] Finally, it should be noted that those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include these modifications and variations.
