[0024] The specific implementation of the embodiment of the utility model is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the embodiment of the utility model, and is not used to limit the embodiment of the utility model.

[0025] The utility model provides a maintenance manhole cover system for a water conservancy project. The maintenance manhole cover system may include: a manhole cover plate 1, a lifting device 2, and a controller 3.

[0026] The manhole cover 1 is used to cover the manhole seat, and the manhole seat is fixed to the wellhead to provide stable support for the manhole cover 1.

[0027] One end of the lifting device 2 is mounted on the panel of the manhole cover 1, and the other end is fixed. In one embodiment, one end of the lifting device 2 is detachably mounted on the panel of the manhole cover 1, and the other end of the lifting device 2 is fixed on a wall, a ceiling or a fixing pile.

[0028] The controller 3 is used to issue a lifting command in the first setting scenario and a lowering command in the second setting scenario. At the same time, the lifting device 2 lifts the manhole cover 1 in response to the lifting command to open the wellhead, and drops the manhole cover 1 to the well seat in response to the lowering command to close the wellhead. Thus, the wellhead is automatically opened and closed by the controller 3, which is convenient for operation and meets the needs of daily operation personnel for maintenance and access.

[0029] In one embodiment, the first set scenario may include: detecting a voice command to open the wellhead, detecting that an indicator appears within a set distance, etc. The second set scenario may include: detecting a voice command to close the wellhead, detecting that an indicator disappears within a set distance, etc.

[0030] That is to say, in addition to being able to directly use buttons to start and close the lifting device 2 in a regular manner, the utility model can also intelligently identify the opening and closing scenes. That is, it automatically sends control signals according to different scenes, and can realize the function of voice control or indicator remote control opening, without having to manually open the lifting device 2. This brings convenience in some occasions where manual operation is inconvenient.

[0031] In one embodiment, the lifting device 2 may be a turning mechanism or a lifting device.

[0032] The flipping mechanism can make the manhole cover 1 rotate along a set side to a set angle. In one embodiment, when the lifting device 2 is a flipping mechanism, the manhole cover 1 can be a flip-type manhole cover, such as Figure 2As shown. The characteristic of the flip-type manhole cover is that the manhole cover can be flipped around a certain axis to open or close the wellhead. This design makes inspection and maintenance work more convenient. For example, the flip-type manhole cover can be connected to the well seat fixed to the wellhead through a flip mechanism. In addition, the set side of the flip-type manhole cover and the well seat can be connected through a hinge 12, so that the flip-type manhole cover can be smoothly rotated when opened or closed. In addition, the traditional flip-type manhole cover has no support, so there is a risk of the manhole cover falling down. In this regard, the flip mechanism can also limit the displacement of the manhole cover after the flip-type manhole cover is opened to a set angle to avoid the danger caused by the sudden fall of the manhole cover.

[0033] In one embodiment, the manhole cover 1 may include a support rod 11 and at least one handle 13. Preferably, two handles 13 are installed on the manhole cover 1. Figure 2 As shown, the manhole cover 1 can be manually opened in an emergency. In this case, since one end of the lifting device 2 mounted on the panel of the manhole cover 1 is detachable, the lifting device 2 can be disassembled from the manhole cover 1 in the event of a failure, and then the manhole cover handle 13 can be manually pulled up to open and close it, and finally the support rod 14 can be used to support the manually opened manhole cover 1 to prevent the manhole cover 1 from suddenly falling down and causing danger.

[0034] Among them, the lifting mechanism can make the manhole cover 1 translate as a whole in the vertical direction. In one embodiment, when the lifting device 2 is a lifting mechanism, the manhole cover 1 is a detachable manhole cover. The main feature of the detachable manhole cover is that the manhole cover can be separated from the well seat, but this method will take up space when opened and placed in daily use. Therefore, the lifting device can be used to control the up and down movement of the detachable manhole cover, and the detachable manhole cover can be raised away from the well seat to open the detachable manhole cover, and lowered to the well seat to close the detachable manhole cover. Since the detachable manhole cover is lifted to a high place, it does not affect the occupation of space, and is particularly suitable for crowded and enclosed occasions such as pump rooms.

[0035] In one embodiment, the lifting device 2 may be a hydraulic structure or a telescopic structure.

[0036] For example, when the lifting device 2 is a telescopic structure, refer to Figure 3 , Figure 4 and Figure 5 As shown in the schematic diagram, one end of the lifting device 2 can be installed on the roof of the water pump layer through the upper fixing frame, and the fixing frame and the inspection manhole cover plate 1 are connected through a cross telescopic structure and controlled by an electric telescopic device to ensure the stability of the lifting and opening and closing of the manhole cover plate 1. In addition, an electric lifting hoisting rope 21 can also be used to realize the electric lifting and opening and closing of the manhole cover. Among them, the cross telescopic structure can include a plurality of interconnected telescopic components, and the telescopic components can include four groups of movable arms cross-connected to each other in turn to realize the above functions.

[0037] In one embodiment, the manhole covers can be divided into multiple types according to different manufacturing processes and uses. For example, the material of the manhole cover can be cast iron, steel, fiberglass or concrete, and manhole covers made of different materials can be used in different scenarios. Specifically, the cast iron manhole cover made of gray cast iron or ductile iron has the advantages of high strength, light weight, corrosion resistance, and not easy to deform, and can be used in cost-insensitive occasions. The steel plate manhole cover made of steel has the advantages of being strong and durable, moderate weight, and low price, and is suitable for a relatively dry and rust-resistant environment. The fiberglass manhole cover made of materials such as glass fiber and resin has the advantages of corrosion resistance, insulation, and light weight, and is suitable for a relatively clean environment. The concrete manhole cover made of concrete has the characteristics of strong load-bearing capacity and good durability, and is suitable for an environment with a lifting mechanism and is not often opened.

[0038] It should also be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, commodity or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, commodity or device. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the process, method, commodity or device including the elements.

[0039] The above are only embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included within the scope of the claims of the present application.
