In all the examples shown and discussed here, any specific value should be construed as merely exemplary, rather than as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that: similar reference numerals and letters indicate similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0018] It should be noted that in the description of the present application, terms such as "first" and "second" in the specification and claims are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein. Moreover, the objects distinguished by "first", "second", etc. are usually of the same type, and the number of objects is not limited. For example, the first object can be one or multiple. In addition, "and / or" in the specification and claims indicates at least one of the connected objects. The character " / ", generally represents an "or" relationship between the associated objects before and after.

[0019] It should be noted that in the description of the present application, the orientation or positional relationships indicated by orientation terms such as "front, back, up, down, left, right", "horizontal, vertical, perpendicular, horizontal" and "top, bottom", etc. are usually based on the orientation or positional relationship shown in the drawings. This is only for the convenience of describing the present application and simplifying the description. Without contrary explanations, these orientation terms do not indicate or imply that the devices or elements referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the protection scope of the present application; the orientation terms "inside and outside" refer to the inside and outside relative to the contour of each component itself.

[0020] It should be noted that in the present application, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. Without further limitations, the element defined by the statement "comprising one..." does not exclude the existence of additional identical elements in the process, method, article or device comprising such element. In addition, it should be pointed out that the scope of the methods and devices in the embodiments of the present application is not limited to performing functions in the order shown or discussed. It may also include performing functions in a substantially simultaneous manner or in a reverse order according to the functions involved.

[0021] As shown in the figure Figure 1 and Figure 2 , the present utility model provides a water supply and drainage manhole cover, which includes a manhole ring 1, a first manhole cover plate 2 and a second manhole cover plate 3 rotatably arranged on the manhole ring 1.

[0022] Wherein, the first manhole cover plate 2 and the second manhole cover plate 3 are connected by a transmission mechanism.

[0023] The driving mechanism drives the first well cover plate 2 and the second well cover plate 3 to rotate and then cooperate to seal and cover the opening of the well ring 1 or open the opening of the well ring 1. The driving mechanism controls the opening and closing of the first well cover plate 2 and the second well cover plate 3 in an automatic manner, without the need for manual turning, thus simplifying the labor force.

[0024] Preferably, the well ring 1 is of a ring structure. Of course, a square or polygonal well ring 1 is also an optional solution, and no specific limitation is made in this embodiment.

[0025] Both the first well cover plate 2 and the second well cover plate 3 are rotatably installed in the well ring 1 through a rotating shaft 4. A baffle 5 and a limiting plate 6 are further provided on the inner wall of the well ring 1. The baffle 5 is arranged between the first well cover plate 2 and the second well cover plate 3, and the limiting plate 6 is arranged outside the first well cover plate 2 and the second well cover plate 3. When the first well cover plate 2 and the second well cover plate 3 are spliced in parallel, the first well cover plate 2 abuts against the upper part of the baffle 5 and the lower part of the limiting plate 6, and the second well cover plate 3 abuts against the lower part of the baffle 5 and the upper part of the limiting plate 6. When the first well cover plate 2 and the second well cover plate 3 rotate to cover the opening of the well ring 1 in parallel, the positioning part 20 formed on the first well cover plate 2 abuts against the upper surface of the side edge of the second well cover plate 3. A sealed connection is formed between the first well cover plate 2 and the well ring 1, between the second well cover plate 3 and the well ring 1, and between the first well cover plate 2 and the second well cover plate 3, which preferably plays a role in water isolation. Reinforcing plates 21 are provided at the lower parts of the first well cover plate 2 and the second well cover plate 3 to improve the structural strength of the first well cover plate 2 and the second well cover plate 3.

[0026] In addition, more specifically, the driving mechanism includes a motor 7, a first crank 8, a second crank 9 and a connecting rod 10. An installation seat 11 is provided outside the well ring 1. The motor 7 is arranged in the installation seat 11. The rotating shaft 4 on the second well cover plate 3 passes through the installation seat 11 and is drivingly connected to the motor 7. One ends of the first crank 8 and the second crank 9 are respectively fixed on the rotating shafts 4 on the first well cover plate 2 and the second well cover plate 3. The two ends of the connecting rod 10 are hingedly connected between the other ends of the first crank 8 and the second crank 9. Therefore, for this water supply and drainage well cover, the well ring 1 is installed on the water supply and drainage well. The motor 7 drives the rotating shaft 4, and the first well cover plate 2 and the second well cover plate 3 are synchronously driven by the first crank 8, the second crank 9 and the connecting rod 10 to turn, without the need for manual opening and closing, realizing automatic opening and closing. When the first well cover plate 2 and the second well cover plate 3 turn to be in parallel and fit together, they seal and cover the opening of the well ring 1 to achieve closing, and turn to other positions to achieve opening.

[0027] The embodiments of the present application have been described above in conjunction with the accompanying drawings. Without conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application is not limited to the above specific implementation manners. The above specific implementation manners are merely illustrative rather than restrictive. Those of ordinary skill in the art, under the inspiration of the present application and without departing from the purpose of the present application and the scope protected by the claims, can also make many forms, all of which fall within the protection scope of the present application.
