AI Technical Summary
The existing manhole covers cannot effectively precipitate silt and sand when rainwater passes, resulting in blockage of sewers, increasing the labor intensity of cleaning personnel and a risk of carbon dioxide poisoning.
A manhole cover with a sediment sedimentation structure is designed, including an upper cover and a lower cover of the manhole. A silt sedimentation area composed of a conical boss and an outer wall is provided in the middle of the lower cover. A multiple water pipe is set up in the middle of the conical boss. After rainwater enters the lower cover through the water hole, silt sediment is first settled in the sedimentation area, and then enters the manhole through the water pipe.
It effectively shortens the time for cleaning silt and silt in the human well, reduces the labor intensity of cleaning personnel, avoids safety hazards in the work in the human well, and saves the construction costs of the human well.

Description
Technical Field
[0001] The utility model relates to the technical field of vehicle wheel manufacturing, in particular to a manhole cover with a sediment sedimentation structure. Background Art
[0002] I believe everyone is familiar with all kinds of manhole covers. The application fields of invisible manhole covers are almost everywhere in our industry and cities. They are commonly seen in factories, airports, community landscape roads, urban sidewalks, motor vehicle lanes, squares, lawns and other fields. Since the advent of manhole covers and their widespread use, most of the manhole covers are made of cement, cast iron, silicon plastic, polymer molded and other materials. The design is divided into round or square manhole covers, and the mud and sand are directly discharged into the sewer manhole through the drainage holes of the manhole covers when it rains. Over time, the underground manhole mud and sand block the sewer, resulting in poor drainage effect, and even blockage of the sewer. People are forced to use manual entry into the sewer for mud and sand cleaning operations, or use simple shovels for dredging on the ground for cleaning. Regardless of the current method of cleaning mud and sand, the labor intensity of manual labor increases, and when the sewer is deep, manual entry into the underground for cleaning is required. In addition to the high labor intensity, there is also the risk of carbon dioxide poisoning. Summary of the invention
[0003] The purpose of the utility model is to provide a manhole cover with a sediment sedimentation structure to solve the problems existing in the above-mentioned background technology.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a manhole cover with a silt sedimentation structure, comprising a manhole upper cover 2, the manhole upper cover 2 is provided with evenly distributed water holes 3, and is characterized in that: a manhole lower cover 6 is provided below the manhole upper cover 2, and a conical boss 4 is provided in the middle of the manhole lower cover 6, which together with the outer wall of the manhole lower cover 6 forms a silt sedimentation area 1; and more than four water pipes 5 are provided in the middle of the conical boss 4.
[0005] Preferably, the pit bottom cover 6 is arranged on a support platform 7 , and the support platform 7 is embedded in the side wall 7 .
[0006] Preferably, the height of the furnace lower cover 6 is greater than 200 mm, and the conical tip of the conical boss 4 fits with the bottom surface of the furnace upper cover 2 .
[0007] Preferably, the upper end surface of the water pipe 5 is 20-30 mm lower than the cone tip of the conical boss 4 .
[0008] Preferably, no water hole 3 is provided above the water pipe 5 .
[0009] Preferably, the bottom diameter of the conical boss 4 is equal to the diameter of the furnace 9 .
[0010] Compared with the prior art, the beneficial effects of the utility model are: first, it shortens the time for cleaning mud and silt in the current pit, and reduces the labor intensity of the pit cleaning personnel; second, it can be modified on the basis of the original ordinary pit cover, adding a mud sedimentation cover, and then using the original ordinary pit cover in conjunction with it, which not only saves the pit construction cost, but also utilizes the existing pit cover, avoiding the waste of the existing pit cover, and can be widely used in industrial enterprises and municipal road rainwater sewage pit systems; third, when cleaning, the upper pit cover is opened, and the personnel can carry out the cleaning operation on the ground without entering the pit for cleaning, avoiding nitrogen asphyxiation accidents in the pit and ensuring the safety of the construction personnel. BRIEF DESCRIPTION OF THE DRAWINGS
[0011] Figure 1 It is a schematic diagram of the structure of the utility model.
[0012] In the figure: 1. Sediment sedimentation area; 2. Kiln cover; 3. Water hole; 4. Conical boss; 5. Water pipe; 6. Kiln cover; 7. Support platform; 8. Side wall; 9. Kiln. DETAILED DESCRIPTION
[0013] The following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the described embodiments are only part of the utility model embodiments, 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.
[0014] See also Figure 1 The utility model provides a technical solution: a manhole cover with a sediment sedimentation structure, comprising a manhole cover 2, and the manhole cover 2 is provided with evenly distributed water holes 3.
[0015] A kiln lower cover 6 is provided below the kiln upper cover 2, and a conical boss 4 is provided in the middle of the kiln lower cover 6, which forms a silt sedimentation area 1 together with the outer wall of the kiln lower cover 6; the height of the kiln lower cover 6 is greater than 200 mm, and the cone tip of the conical boss 4 is in contact with the bottom surface of the kiln upper cover 2; at the same time, more than four water pipes 5 are provided in the middle of the conical boss 4, and the upper end surface of the water pipe 5 is 20-30 mm lower than the cone tip of the conical boss 4, and no water hole 3 is provided above the water pipe 5.
[0016] The furnace bottom cover 6 is arranged on the support platform 7, and the support platform 7 is embedded in the side wall 8; and the bottom diameter of the conical boss 4 is equal to the diameter of the furnace 9.
[0017] When rainwater enters the kiln cover 6 from the water hole 3, it will slide down from the conical boss 4 or directly fall into the silt sedimentation area 1. At the same time, the depth is deep, and the rainwater mixed with silt will not directly enter the kiln 9, but will continue to accumulate and settle at the bottom of the sedimentation area 1. When there is a lot of rainwater, the rainwater will enter the kiln 9 from the water pipe 5, avoiding more than 70% of the silt from falling into the kiln 9 with the rainwater.
[0018] Although embodiments of the utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
