Description

Technical Field

[0001] This utility model relates to the field of ductile iron manhole cover technology, specifically an adjustable-opening ductile iron manhole cover. Background Technology

[0002] Manhole covers are used to cover deep wells in roads or homes to prevent people or objects from falling in. They can be classified by material, such as metal manhole covers, high-strength fiber cement concrete manhole covers, and resin manhole covers, and are generally round or square. They can be used in green belts, sidewalks, motor vehicle lanes, docks, alleys, etc. Ductile iron manhole covers are made of ductile iron, but current ductile iron manhole covers have fixed opening sizes. In seasons or regions with varying rainfall, fixed openings are difficult to flexibly adapt to drainage needs, potentially leading to poor drainage or resource waste. Therefore, we propose an adjustable-opening ductile iron manhole cover. Utility Model Content

[0003] The purpose of this utility model is to provide an adjustable opening ductile iron manhole cover, which has the advantage of adjustable opening size. This solves the problem that the opening size of current ductile iron manhole covers is fixed, and the fixed opening is difficult to flexibly adapt to drainage needs in different seasons or regions with different rainfall, which may lead to poor drainage or waste of resources.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an adjustable-opening ductile iron manhole cover, comprising a manhole cover body, a first groove being provided at the middle of the top of the manhole cover body, a receiving groove being provided at the bottom of the inner cavity of the first groove, a rotating rod being rotatably connected to the bottom of the inner cavity of the receiving groove via a bearing, the bottom of the rotating rod extending to the lower end of the bottom of the manhole cover body, a baffle being fixedly connected to the bottom of the rotating rod, and openings being provided at both the left and right ends of the top of the manhole cover body, with a guide port being provided at the bottom of the opening.

[0005] Preferably, slots are provided on both the left and right sides of the inner cavity of the first groove, a cover plate is movably connected to the inner cavity of the first groove, and mounting grooves are provided on both the left and right sides of the cover plate. A telescopic rod is fixedly connected to the side of the inner cavity of the mounting groove, a spring is sleeved on the outer surface of the telescopic rod, and a plug is fixedly connected to the other end of the telescopic rod. The plug is movably connected to the inner cavity of the slot.

[0006] Preferably, a second groove is provided at both the left and right ends of the top of the cover plate, and an opening is provided between the second groove and the mounting groove.

[0007] Preferably, a movable plate is fixedly connected to the top of the insert block, and the top of the movable plate extends into the inner cavity of the second groove.

[0008] Preferably, a handle is fixedly connected to the top of the rotating rod, and a slot is formed on the handle.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. This utility model uses a handle to drive the rotating rod to rotate, which in turn drives the baffle to rotate. The size of the drainage opening at the bottom of the manhole cover can be adjusted according to actual needs. For example, the drainage opening can be reduced when the rainfall is small or when traffic needs to be restricted, and the drainage opening can be enlarged when the rainfall is large, thereby improving drainage efficiency and flexibility of use.

[0011] 2. This utility model can move the insert block by pushing the movable plate. When it is necessary to remove the cover plate, push the movable plate to compress the spring and telescopic rod of the insert block, and the cover plate can be easily removed. Attached Figure Description

[0016] 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.

[0017] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. Example 1

[0018] Please see Figs. 1-3As shown, this utility model provides an adjustable opening ductile iron manhole cover, including a manhole cover body 1. A first groove 2 is provided at the middle of the top of the manhole cover body 1. A receiving groove 6 is provided at the bottom of the inner cavity of the first groove 2. A rotating rod 8 is rotatably connected to the bottom of the inner cavity of the receiving groove 6 via a bearing. The bottom of the rotating rod 8 extends to the lower end of the bottom of the manhole cover body 1. A baffle 9 is fixedly connected to the bottom of the rotating rod 8. A first through-hole 3 is provided at both the left and right ends of the top of the manhole cover body 1. A guide port 18 is provided at the bottom of the first through-hole 3. A handle 7 is fixedly connected to the top of the rotating rod 8. A slot 10 is provided on the handle 7.

[0019] This technical solution uses a throttle 7 to drive the rotating rod 8 to rotate, which in turn drives the baffle 9 to rotate. The size of the drainage port 18 at the bottom of the manhole cover body 1 can be adjusted according to actual needs. For example, when the rainfall is small or traffic needs to be restricted, the drainage port 18 can be reduced, and when the rainfall is large, the drainage port 18 can be enlarged, thereby improving drainage efficiency and flexibility of use. Example 2

[0020] Based on Embodiment 1, this utility model is as follows: Figs. 1-3 As shown, slots 13 are provided on both the left and right sides of the inner cavity of the first groove 2. A cover plate 4 is movably connected to the inner cavity of the first groove 2. Mounting grooves 15 are provided on both the left and right sides of the cover plate 4. A telescopic rod 17 is fixedly connected to the side of the inner cavity of the mounting groove 15. A spring 16 is sleeved on the outer surface of the telescopic rod 17. A plug 14 is fixedly connected to the other end of the telescopic rod 17. The plug 14 is movably connected to the inner cavity of the slot 13. A second groove 5 is provided on both the left and right ends of the top of the cover plate 4. A second opening 11 is provided between the second groove 5 and the mounting groove 15. A movable plate 12 is fixedly connected to the top of the plug 14. The top of the movable plate 12 extends into the inner cavity of the second groove 5.

[0021] This technical solution allows the insertion block 14 to move by pushing the movable plate 12. When it is necessary to remove the cover plate 4, pushing the movable plate 12 causes the insertion block 14 to compress the spring 16 and the telescopic rod 17, making it easy to remove the cover plate 4.

[0022] The working principle of this utility model is as follows: the handle 7 can drive the rotating rod 8 to rotate, which in turn drives the baffle 9 to rotate. The size of the drainage port 18 at the bottom of the manhole cover body 1 can be adjusted according to actual needs. For example, when the rainfall is small or passage needs to be restricted, the drainage port 18 can be reduced, and when the rainfall is large, the drainage port 18 can be enlarged to improve drainage efficiency and flexibility of use. By pushing the movable plate 12, the insertion block 14 can be moved. When it is necessary to remove the cover plate 4, push the movable plate 12 so that the insertion block 14 compresses the spring 16 and the telescopic rod 17, and the cover plate 4 can be easily removed.
