Abstract
Description
Technical Field

[0002] Urban drainage systems, gas, and power facilities, etc. are all laid using underground pipelines. Among them, for the urban underground drainage system, it is mainly to avoid waterlogging in the city during the rainy season. Therefore, whether the process of surface water entering the underground drainage pipeline is smooth is a crucial point.
[0003] As one of the entrances to the sewer pipeline, the traditional manhole cover also takes into account the function of introducing road surface water into the sewer. The traditional manhole cover is provided with arc-shaped through holes at the edge, and the arc-shaped through holes can be used to drain water. However, during the drainage process, there are some waste items such as garbage and sundries in the water flow. As a result, during the process of the manhole cover guiding drainage, the water flow carries the sundries through the arc-shaped through holes into the sewer together. However, during this process, the sundries easily cover the arc-shaped through holes, causing the arc-shaped through holes to be blocked, reducing the water flow discharge speed, and eventually being completely blocked, resulting in serious water accumulation on the road surface.

DETAILED DESCRIPTION
[0028] The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which presently preferred embodiments of the invention are shown. However, the invention can be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness, and will fully convey the scope of the invention to those skilled in the art.
[0029] Example 1: A drainage manhole cover for gardening projects, such as Figures 1-4As shown, it includes an annular groove frame 1, a support ring frame 2, a ring cover 3, a cover body 4, an intermediate ring 5 and an airbag ring 6. A drainage port 1a is opened at the bottom of the annular groove frame 1. The drainage port 1a can be located at the bottom of the annular groove frame 1 or on the lower side wall of the annular groove frame 1. The annular groove frame 1 is divided into an inner ring and an outer ring. The ring cover 3 is placed on the groove of the annular groove frame 1. The ring cover 3 has a drainage port 1a. The drainage port 1a at the bottom of the annular groove frame 1 is smaller than the drainage port 1a on the ring cover 3. The support ring frame is welded to the inner ring side wall of the annular groove frame 1. 2. A cover body 4 is placed on the support ring frame 2. The cover body 4 is located in the inner ring of the annular groove frame 1. An intermediate collar 5 is slidably placed between the cover body 4 and the ring cover 3. An airbag ring 6 is slidably placed in the groove of the annular groove frame 1. The airbag ring 6 is fixedly connected to the intermediate collar 5. When the drain port 1a of the annular groove frame 1 is blocked or the drainage volume cannot keep up with the water intake, the water level in the annular groove frame 1 rises and lifts the airbag ring 6, thereby lifting the intermediate collar 5. When the intermediate collar 5 is lifted, the annular through-slit formed between the cover body 4 and the ring cover 3 is exposed.
[0030] like Figure 5 As shown, it also includes a net frame 7. The inner ring of the annular groove frame 1 is slidably placed on the net frame 7. If road water carries leaves and waste paper into the sewer through the annular gap, it will be blocked by the net frame 7 to prevent it from entering the sewer. Workers can open the cover 4 to clean these leaves, waste paper and impurities regularly.
[0031] like Figure 6 and Figure 7 As shown, it also includes a debris removal component 8, and the debris removal component 8 is set at the bottom of the annular trough frame 1; the debris removal component 8 includes a covering ring 81, an inclined plate 82, a compression spring 83 and a push rod 85. The bottom of the annular trough frame 1 is rotatably connected to the covering ring 81. When the drain outlet 1a of the annular trough frame 1 is opened at the bottom, the covering ring 81 needs to open a through opening that fits with the drain outlet 1a of the annular trough frame 1 to avoid blocking the drain outlet 1a of the annular trough frame 1. The inclined plate 82 is fixed to the covering ring 81 by bolts, and the push rod 85 is fixed to the net frame 7. The push rod 85 is in sliding contact with the inclined plate 82, and the covering ring 81 and the annular trough frame 1 are fixed together. The compression spring 83, the covering ring 81 and the annular groove frame 1 are both provided with a debris discharge opening 84, and the compression spring 83 is used to keep the debris discharge openings 84 at the covering ring 81 and the annular groove frame 1 rotated and staggered, and when the net frame 7 is pressed downward, the top rod 85 will apply a downward force along the inclined plate 82, thereby pushing the inclined plate 82 to displace, and finally prompting the covering ring 81 to rotate, thereby making the debris discharge openings 84 at the covering ring 81 and the annular groove frame 1 overlap with each other. This operation can leave a larger discharge opening when it is necessary to clean the residual mud and impurities inside the annular groove frame 1, so as to facilitate the cleaning of the debris inside the annular groove frame 1.
[0032] like Figure 8As shown, it also includes a stirring component 9, and the stirring component 9 is arranged on the net frame 7; the stirring component 9 includes a support frame 91, a spiral fan 92 and a toggle plate 93. The support frame 91 is welded on the net frame 7, and the spiral fan 92 is rotatably connected to the support frame 91. The number of blades of the spiral fan 92 needs to be controlled according to actual conditions. The smaller the distance between the blades, the easier it is for the incoming debris to get stuck in the blades. The toggle plate 93 is fixed at the center of the spiral fan 92, and the toggle plate 93 is located at the lower part of the net frame 7. As the spiral fan 92 rotates, the toggle plate 93 can be rotated together.
[0033] like Figure 9 As shown, it also includes a limiting member 10, and the limiting member 10 is slidably connected on the middle ring sleeve. The limiting member 10 is in contact with the cover body 4. The limiting member 10 is composed of a limiting plate and a cylindrical spring. The cylindrical spring is used to keep the limiting plate horizontally above the cover body 4, so as to prevent the water in the sewer from overflowing and washing away the cover body 4. The limiting member 10 is used to limit the cover body 4.
[0034] like Figure 10 and Figure 11 As shown, a partition assembly 11 is also included. The partition assembly 11 is set on the annular trough frame 1; the partition assembly 11 includes an outer ring frame 111, a blocking frame 112 and a pull column 113. The outer ring of the annular trough frame 1 is fixed to the outer ring frame 111. Road water first needs to pass through the groove between the outer ring frame 111 and the outer ring of the annular trough frame 1, and then flow from the groove to the drainage port 1a of the ring cover 3. The annular trough frame 1 is longitudinally slidably connected to the blocking frame 112. 19 flexible rods are evenly distributed on the blocking frame 112. While the flexible rods can play a blocking role, they can also prevent accidental stepping or In case of accidental touch causing damage to objects, the blocking frame 112 is located in the groove between the annular groove frame 1 and the outer ring frame 111. When road water passes through the groove, some debris will be blocked by the blocking frame 112. The water flow after the debris is blocked enters the drain outlet 1a, which can further reduce the occurrence of blockage. A pull column 113 is fixed to the blocking frame 112, and a pull ring is fixed to the top of the pull column 113. When a lot of debris accumulates in the groove, the pull ring can be pulled to pull up the blocking frame 112 to clean up the debris on the blocking frame 112, thereby avoiding long-term accumulation and loss of the blocking effect.
[0035] like Figure 12 As shown, a pull handle 12 is further included. The pull handle 12 is hinged on the cover body 4. When the cover body 4 needs to be pulled out, the pull handle 12 can be pulled up, and the pull handle 12 can be used to facilitate the disassembly of the cover body 4.
[0036] Under normal road drainage conditions, water flows along the drainage port 1a of the ring cover 3 into the annular trough frame 1 and is discharged from the drainage port 1a at the bottom of the annular trough frame 1. When the road water flow accumulates and becomes larger, the drainage volume of the drainage port 1a is difficult to effectively drain the water, which will cause water accumulation in the annular trough frame 1, or the drainage port 1a in the annular trough frame 1 will be blocked to a certain extent. At this time, the airbag ring 6 is in contact with the water surface, and as the water level in the annular trough frame 1 rises, the middle sleeve 5 is lifted up. After the middle sleeve 5 is lifted up, an annular gap will be exposed. The water accumulated on the road will quickly flow from the inner ring of the annular trough frame 1 into the sewer pipe through the annular gap, thereby increasing the drainage flow of the drainage port 1a, avoiding the accumulation of road water, and the impact of the water flow drives the propeller fan 92 to rotate together with the toggle plate 93. After the leaves and other impurities contained in the water fall into the mesh frame 7, the toggle plate 93 can be used to push away the impurities accumulated in one place, avoiding concentrated accumulation and blockage.
