Description

Technical Field

[0001] This utility model relates to the field of municipal engineering technology, specifically to a ductile iron storm drain cover with protective load-bearing components. Background Technology

[0002] Manhole covers are used to cover deep wells in roads or homes, primarily to prevent people or objects from falling in, while also serving a drainage function. They are typically made of materials such as ductile iron, stainless steel, and resin, and come in different specifications and sizes to suit various application scenarios and needs.

[0003] Besides ductile iron, there are also cast steel manhole covers available. Different locations, such as municipal roads, parking lots, and factories, will have different design and specification requirements. In terms of manufacturing processes, ductile iron is widely used in the production of manhole covers due to its high strength, toughness, and corrosion resistance.

[0004] Ductile iron manhole covers undergo special surface treatment, resulting in excellent wear resistance and the ability to withstand friction and abrasion from passing vehicles. Compared to traditional cast iron manhole covers, ductile iron covers are lighter, making them easier to transport, install, and maintain.

[0005] Although ductile iron manhole covers have certain advantages due to their material properties, traditional ductile iron manhole covers have relatively simple structural designs, low load-bearing capacity, and low stability. Therefore, a ductile iron manhole cover with protective load-bearing components is proposed. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a ductile iron rainwater and sewage manhole cover with protective load-bearing components, which has advantages such as high load-bearing capacity and good stability. It solves the problems of relatively low load-bearing capacity and low stability of traditional ductile iron rainwater and sewage manhole covers due to their simple structural design.

[0007] To achieve the aforementioned objectives of high load-bearing capacity and good stability, this utility model provides the following technical solution: a ductile iron rainwater and sewage manhole cover with a protective load-bearing component, comprising a chassis, a load-bearing plate movably connected to the top of the chassis, a load-bearing component on the outer side of the load-bearing plate, and a top cover component on the top of the load-bearing plate;

[0008] The load-bearing component includes a stabilizing rubber ring disposed on the outside of the chassis, several connecting plates fixed to the inner side wall of the load-bearing plate, a stabilizing plate fixedly installed on the side of the connecting plates, a limiting slot opened on the top of the stabilizing plate, several limiting blocks fixedly installed on the inner bottom wall of the load-bearing plate, and a stabilizing seat inserted into the limiting slot.

[0009] The top cover component includes a top cover plate movably connected to the top of the support plate, several drainage grooves on the top of the top cover plate, a water guide groove on the top of the top cover plate, drainage holes on the bottom wall of the water guide groove, an annular groove inside the top cover plate, and several water outlet holes at the bottom of the annular groove.

[0010] Furthermore, the chassis is an L-shaped annular disk with a chamfered surface on the top side of the chassis. The stabilizing rubber ring is an annular structure that wraps around the bottom surface of the outer side of the bearing disk and is slidably connected to both the bearing disk and the chassis.

[0011] Furthermore, the bearing plate is a Z-shaped annular plate, with its bottom embedded inside the chassis and slidably connected to the inner sidewall of the chassis.

[0012] Furthermore, the top of the stabilizing plate is provided with a buffer pad, the limiting slot is a cross-shaped slot, and the bottom of the stabilizing base is provided with a cross-shaped locking block that works in conjunction with the limiting slot.

[0013] Furthermore, the top of the top cover plate has an insertion slot, and the stabilizing seat is embedded in the insertion slot so that the cross-shaped locking block is embedded in the limiting slot. The bottom of the top cover plate has several locking slots for use with the limiting block.

[0014] Furthermore, the number of drainage holes is greater than that of water outlet holes, the size of the drainage holes is smaller than that of the water outlet holes, the drainage holes vertically penetrate the top wall of the annular groove, and the water outlet holes vertically penetrate the bottom wall of the annular groove.

[0015] Furthermore, the hydrophobic holes and water outlet holes are evenly and alternately distributed on the upper and lower walls of the annular groove.

[0016] Compared with the prior art, this utility model provides a ductile iron storm drain cover with a protective load-bearing component, which has the following beneficial effects:

[0017] 1. This ductile iron storm drain cover with protective load-bearing components is installed by placing the chassis into the hole where the cover needs to be installed, and then putting the stabilizing rubber ring on the top side of the chassis. After the top cover plate is embedded in the chassis, the top cover plate squeezes the stabilizing rubber ring. The stabilizing rubber ring deforms and stretches after being squeezed, tightly wrapping the chassis. At the same time, the outer side of the stabilizing rubber ring squeezes the inner wall of the hole. The reaction force generated presses the chassis into the hole, so that the chassis can be stably arranged on the inner wall of the hole.

[0018] 2. This ductile iron storm drain cover with protective load-bearing components works by inserting a stabilizing seat and a cross-shaped locking block into the insertion slot. The cross-shaped locking block smoothly embeds into the limiting slot, thus limiting the center position of the top cover plate to prevent rotation. Water flows through the drainage groove and into the guide groove, then through the drainage hole and into the annular groove. After flowing along the annular groove, the water flows smoothly out through the outlet hole. When a vehicle presses on the top cover plate, the limiting block inside the load-bearing plate limits the locking slot, preventing the top cover plate from moving. This solves the problem of traditional ductile iron storm drain covers having relatively simple structural design, low load-bearing capacity, and low stability. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1 to 5 In this embodiment, a ductile iron rainwater and sewage manhole cover with a protective bearing component includes a chassis 1, a bearing plate 2 movably connected to the top of the chassis 1, a bearing component 3 on the outside of the bearing plate 2, and a top cover component 4 on the top of the bearing plate 2.

[0027] The load-bearing component 3 includes a stabilizing rubber ring 31 disposed on the outside of the chassis 1, several connecting plates 32 fixed to the inner side wall of the load-bearing plate 2, a stabilizing plate 33 fixedly installed on the side of the connecting plate 32, a limiting slot 34 opened on the top of the stabilizing plate 33, several limiting blocks 35 fixedly installed on the inner bottom wall of the load-bearing plate 2, and a stabilizing seat 36 inserted into the limiting slot 34.

[0028] The top cover component 4 includes a top cover plate 41 movably connected to the top of the support plate 2, a plurality of drainage grooves 42 formed on the top of the top cover plate 41, a water guide groove 43 formed on the top of the top cover plate 41, drainage holes 44 formed on the bottom wall of the water guide groove 43, an annular groove 45 formed inside the top cover plate 41, and a plurality of water outlet holes 46 formed at the bottom of the annular groove 45.

[0029] In this embodiment, the chassis 1 is an L-shaped annular disk, and the top side of the chassis 1 is provided with a chamfered surface. The stabilizing rubber ring 31 is an annular structure that wraps around the bottom surface of the outer side of the bearing disk 2 and is slidably connected to both the bearing disk 2 and the chassis 1.

[0030] A stabilizing rubber ring 31 is provided on the outside of the chassis 1. When the bearing plate 2 is pressed down, the top of the chassis 1 will simultaneously press the stabilizing rubber ring 31 to expand, thereby wrapping around the outside of the chassis 1. This allows the outer surface of the chassis 1 to press against the borehole wall, thereby improving the stability of the chassis 1 in the borehole.

[0031] In this embodiment, the support plate 2 is a Z-shaped annular plate, and the bottom of the support plate 2 is embedded inside the chassis 1 and slidably connected to the inner sidewall of the chassis 1.

[0032] The support plate 2 is embedded inside the chassis 1 to form a preliminary combination of chassis 1 and support plate 2.

[0033] It should be noted that the sewer hole has a T-shaped structure, which provides support for the bottom of the support plate 2.

[0034] In this embodiment, a buffer pad is provided on the top of the stabilizing disk 33, the limiting slot 34 is a cross-shaped slot, and a cross-shaped locking block 37 is provided at the bottom of the stabilizing base 36 to cooperate with the limiting slot 34.

[0035] In this embodiment, the top of the top cover plate 41 is provided with a plug-in slot 47, and the stabilizing seat 36 is embedded in the plug-in slot 47 so that the cross-shaped locking block 37 is embedded in the limiting slot 34. The bottom of the top cover plate 41 is provided with a number of locking slots 48 that are used in conjunction with the limiting block 35.

[0036] In this embodiment, the number of drainage holes 44 is greater than that of water outlet holes 46, the size of drainage holes 44 is smaller than that of water outlet holes 46, the drainage holes 44 vertically penetrate the top wall of the annular groove 45, and the water outlet holes 46 vertically penetrate the bottom wall of the annular groove 45.

[0037] In this embodiment, the hydrophobic holes 44 and the water outlet holes 46 are evenly and alternately distributed on the upper and lower walls of the annular groove 45.

[0038] The working principle of the above embodiments is as follows:

[0039] By placing the chassis 1 into the hole where the manhole cover needs to be installed, and then putting the stabilizing rubber ring 31 on the top side of the chassis 1, the top cover plate 41 is embedded inside the chassis 1. The top cover plate 41 squeezes the stabilizing rubber ring 31. After being squeezed, the stabilizing rubber ring 31 deforms and stretches to tightly wrap the chassis 1. At the same time, the outer side of the stabilizing rubber ring 31 squeezes the inner wall of the hole. The resulting reaction force presses the chassis 1 into the hole, so that the chassis 1 can be stably arranged on the inner wall of the hole.

[0040] In addition, by inserting the stabilizing seat 36 and the cross-shaped locking block 37 into the insertion slot 47, the cross-shaped locking block 37 is smoothly embedded into the interior of the limiting slot 34. After passing through the drainage groove 42, the water flows into the interior of the water guide groove 43, passes through the drainage hole 44, and enters the interior of the annular groove 45. After flowing along the annular groove 45, the water flows smoothly out through the outlet hole 46. When the vehicle presses on the top cover plate 41, the limiting block 35 inside the bearing plate 2 limits the locking slot 48, preventing the top cover plate 41 from moving. At the same time, the stabilizing seat 36 limits the center position of the top cover plate 41, preventing the top cover plate 41 from rotating. This solves the problem that traditional ductile iron rainwater and sewage manhole covers have relatively simple structural design, relatively low load-bearing capacity, and low stability.

[0041] All electrical components mentioned in the text are electrically connected to the main controller and power supply. The main controller can be a conventional and known device such as a computer, and the existing publicly available power connection technology will not be elaborated in the text.
