Description

Technical Field

[0001] The present application relates to the field of manhole covers, and in particular, to an anti-blocking structure for drainage holes of manhole covers. Background Art

[0002] There will be many underground pipelines in urban construction, such as sewers, underground gas pipelines, water pipelines, power pipelines, communication pipelines, national defense pipelines, etc. These pipelines must have an outlet to the ground at intervals. The section from the pipeline to the ground is called a manhole. The manhole opening is usually flush with the ground, so a cover is needed. The cover used to cover the manhole is called a manhole cover. The manhole cover includes a manhole cover base and a manhole cover body, and the manhole cover body has a drainage hole. The existing drainage holes can generally meet the needs of drainage, but when debris flows in with the water flow, it is easy to block the drainage holes, and some debris will flow into the underground passage with the drainage outlet.

[0003] The patent with application number 202120360666.3 discloses a manhole cover that prevents debris from passing through and prevents blockage. It includes a manhole cover base and a manhole cover body, and the manhole cover body is provided with drainage holes arranged at intervals. It is characterized in that it also includes a debris baffle arranged in the manhole cover base, and the debris baffle is provided with water holes corresponding to the drainage holes and arranged at intervals. The debris baffle is also provided with a baffle mounting port, and a square well hole is provided inside the manhole cover base. The manhole cover base is provided with a base surrounding edge, and a cover body receiving edge is provided inside the base surrounding edge. A baffle receiving edge is provided below the cover body receiving edge, and a baffle positioning protrusion is provided on the baffle receiving edge. The debris entering the manhole cover is effectively blocked on the debris baffle.

[0004] Although the baffle can block and collect debris in the above structure, since the size of the water hole is much smaller than the drainage groove on the manhole cover, the collected debris will block the water hole, and after blockage, the excess debris will block the drainage groove on the surface of the manhole cover, thereby seriously affecting the normal drainage of the manhole cover. Utility Model Content

[0005] The content of this application is used to introduce concepts in a brief form, which will be described in detail in the detailed implementation section below. The content of this application is not intended to identify the key features or essential features of the technical solution claimed for protection, nor is it intended to limit the scope of the technical solution claimed for protection.

[0006] In order to solve the technical problems mentioned in the above background technology section, some embodiments of the present application provide a manhole cover drainage hole anti-blocking structure.

[0007] A manhole cover drainage hole anti-blocking structure comprises: a manhole drainage frame and a manhole cover plate embedded in the top of the manhole drainage frame; the top of the side wall of the manhole drainage frame is symmetrically provided with expansion grooves, and a storage box is fixed to the bottom end of the manhole drainage frame, the hollow cavity of the storage box is configured as a accommodating bin, and the top of the side wall of the storage box is symmetrically provided with drainage grooves, wherein a filter plate is installed at the bottom end of the storage box, and the side wall of the expansion groove is elastically plugged with an anti-blocking plate.

[0008] By opening an expansion groove on the side wall of the manhole drainage frame, an anti-blocking plate is elastically arranged on the side wall of the expansion groove, and a fixed mesh plate is embedded in the anti-blocking plate to assist drainage. During the drainage process, the water inlet groove on the top of the manhole cover is blocked by debris and causes the water level to rise. The rising water level causes the pressure on the side wall of the anti-blocking plate to increase, thereby squeezing the anti-blocking plate and the spring in the positioning groove, causing the anti-blocking plate to slide into the manhole drainage frame, and during the sliding process, the blockage and water flow on the side wall of the anti-blocking plate enter the storage box. The blockage is at the bottom of the storage box, and the water flow is discharged along the drainage groove on the top of the storage box, which is convenient for the instantaneous discharge of blocked debris and water flow, thereby improving the anti-blocking effect of the manhole drainage frame.

[0009] Furthermore, the manhole cover is fitted and plugged into the top of the manhole drainage frame, and a plurality of water inlet grooves are provided in a rectangular array at the top of the manhole cover.

[0010] Furthermore, the side walls of the manhole drainage frame are fixed with reinforcing ribs in a rectangular array, and the top of the manhole drainage frame is provided with a plurality of mounting holes arranged alternately with the reinforcing ribs.

[0011] Furthermore, bolts are embedded in the plurality of mounting holes, and the bolt threads are inserted at the center of the inner wall of the mounting hole.

[0012] Furthermore, the filter plate is inserted into the storage box and fixedly connected to the inner wall of the containing chamber, and a filter element is fixedly installed in the filter plate.

[0013] Furthermore, a mesh plate is fixed in the anti-blocking plate, and protrusions are provided at both ends of the anti-blocking plate.

[0014] Furthermore, positioning grooves communicating with the telescopic grooves are provided on both sides of the inner wall of the manhole drainage frame, and the protrusions are fitted and inserted in the positioning grooves.

[0015] Furthermore, a spring is embedded in the positioning groove, and two ends of the spring are fixedly connected to the protruding portion and the inner wall of the positioning groove respectively.

[0016] The beneficial effect of the present application is that it provides an anti-blocking structure for drainage holes of manhole covers.

[0017] By opening an expansion groove on the side wall of the manhole drainage frame, an anti-blocking plate is elastically arranged on the side wall of the expansion groove, and a fixed mesh plate is embedded in the anti-blocking plate to assist drainage. During the drainage process, the water inlet groove on the top of the manhole cover is blocked by debris and causes the water level to rise. The rising water level causes the pressure on the side wall of the anti-blocking plate to increase, thereby squeezing the anti-blocking plate and the spring in the positioning groove, causing the anti-blocking plate to slide into the manhole drainage frame, and during the sliding process, the blockage and water flow on the side wall of the anti-blocking plate enter the storage box. The blockage is at the bottom of the storage box, and the water flow is discharged along the drainage groove on the top of the storage box, which is convenient for the instantaneous discharge of blocked debris and water flow, thereby improving the anti-blocking effect of the manhole drainage frame.

[0031] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0032] A manhole cover drainage hole anti-blocking structure, comprising a manhole drainage frame 1 and a manhole cover plate 3 embedded in the top of the manhole drainage frame 1; a telescopic groove 15 is symmetrically opened at the top of the side wall of the manhole drainage frame 1, and a storage box 8 is fixed to the bottom of the manhole drainage frame 1, the hollow cavity of the storage box 8 is set as a storage bin 13, and a drainage groove 7 is symmetrically opened at the top of the side wall of the storage box 8, wherein a filter plate 14 is installed at the bottom of the storage box 8, and an anti-blocking plate 9 is elastically inserted into the side wall of the telescopic groove 15, and a fixed filter plate 14 is embedded in the anti-blocking plate 9. The fixed mesh plate 11 is used to assist in drainage. During the drainage process, the water inlet groove 2 on the top of the manhole cover 3 is blocked by debris and causes the water level to rise. The rising water level causes the pressure on the side wall of the anti-blocking plate 9 to increase, thereby squeezing the anti-blocking plate 9 and the spring 16 in the positioning groove 17, causing the anti-blocking plate 9 to slide into the manhole drainage frame 1, and during the sliding process, the blockage on the side wall of the anti-blocking plate 9 and the water flow enter the storage box 8. The blockage is at the bottom of the storage box 8, and the water flows out along the drainage groove 7 at the top of the storage box 8.

[0033] The manhole cover 3 is fitted and plugged into the top of the manhole drainage frame 1, and the top of the manhole cover 3 is provided with multiple water inlet grooves 2 in a rectangular array. The water inlet grooves 2 are responsible for most of the water discharge. When the water flow is too large, the top of the water inlet groove 2 will be blocked. During the emergency dredging of the telescopic groove 15, the debris on the top of the water inlet groove 2 is affected by the water flow and falls off from the top of the manhole cover 3, so that the water inlet groove 2 can be drained again. The side wall of the manhole drainage frame 1 is fixed with reinforcing ribs 4 in a rectangular array, and the top of the manhole drainage frame 1 is provided with multiple mounting holes 6 staggered with the reinforcing ribs 4, and bolts 5 are embedded in the multiple mounting holes 6, and the bolts 5 are threadedly inserted at the center of the inner wall of the mounting hole 6.

[0034] The filter plate 14 is inserted into the storage box 8 and fixedly connected to the inner wall of the storage bin 13, and a filter element 10 is fixedly installed in the filter plate 14. The filter element 10 is responsible for discharging the residual water in the debris and cleaning the debris by opening the manhole cover 3 after the discharge.

[0035] A mesh plate 11 is fixed in the anti-blocking plate 9, and protrusions 12 are provided at both ends of the anti-blocking plate 9. Positioning grooves 17 connected with the telescopic groove 15 are provided on both sides of the inner wall of the manhole drainage frame 1. The protrusion 12 is fitted and inserted in the positioning groove 17. A spring 16 is embedded in the positioning groove 17. The two ends of the spring 16 are respectively fixedly connected to the protrusion 12 and the inner wall of the positioning groove 17. The spring 16 is squeezed during the instantaneous discharge process, and after the discharge, the elastic force of the spring 16 pushes the protrusion 12 to reset the anti-blocking plate 9. At the same time, the two ends of the spring 16 are fixedly connected to prevent the anti-blocking plate 9 from falling off from the telescopic groove 15.

[0036] Working principle: A fixed mesh plate 11 is embedded in the anti-blocking plate 9 to assist in drainage. During the drainage process, the water inlet groove 2 on the top of the manhole cover 3 is blocked by debris and causes the water level to rise. The rising water level causes the pressure on the side wall of the anti-blocking plate 9 to increase, thereby squeezing the anti-blocking plate 9 and the spring 16 in the positioning groove 17, causing the anti-blocking plate 9 to slide into the manhole drainage frame 1, and during the sliding process, the blockage on the side wall of the anti-blocking plate 9 and the water flow enter the storage box 8. The blockage is at the bottom of the storage box 8, and the water flows out along the drainage groove 7 at the top of the storage box 8.

[0037] The above descriptions are only some preferred embodiments of the present disclosure and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by a specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalent features without departing from the above-mentioned inventive concept. For example, the above-mentioned features are replaced with the technical features with similar functions disclosed in the embodiments of the present disclosure (but not limited to) and the technical solutions formed.
