[0002] Vertical axial flow pump station is a type of pump widely used at home and abroad. The pump station is generally installed below the ground. To facilitate repair and maintenance, maintenance ports are left around the pump station. The upper end of the maintenance port is equipped with a cover that can withstand a certain pressure and facilitate the passage of pedestrians and small vehicles.

[0003] The existing maintenance opening and closing process has a low degree of automation. In addition, there is no safety guardrail around the cover after it is opened, which poses a certain safety hazard. To this end, we propose an automatic opening and closing maintenance opening cover device. Utility Model Content

[0004] In view of the shortcomings and defects in the existing technology, the purpose of the present invention is to provide an automatic opening and closing maintenance port cover device, which solves the problem that the opening and closing process of the maintenance port cover device in the existing technology has a relatively low degree of automation.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions: an automatic opening and closing maintenance port cover device, comprising a basic frame, a movable cover and a hinge mechanism, the basic frame comprising an annular upper fixed plate, an annular lower skirting board and an annular fence, the fence is fixedly connected between the upper fixed plate and the lower skirting board, there are multiple movable covers, and the shape of the movable cover is a fan ring, each movable cover is hingedly connected to the inner side of the upper end of the upper fixed plate by a hinge mechanism, after unfolding, multiple movable covers are formed around to form a circular ring, and each movable cover is connected to the basic frame by a first electric cylinder that can drive it to flip, and the basic frame is supported on the maintenance port equipment by a second electric cylinder that can drive it to rise and fall.

[0006] As a further improvement of the present invention, the fence includes a plurality of annular round rods and a plurality of vertical round rods, the plurality of annular round rods are coaxially arranged up and down, and the vertical round rods are welded to the plurality of annular round rods.

[0007] As a further improvement of the present invention, one end of the first electric cylinder is hingedly connected to the basic frame through an hinge seat, and the other end is hingedly connected to the movable cover through an hinge seat.

[0008] As a further improvement of the present invention, a guide mechanism is further provided between the basic frame and the maintenance opening equipment.

[0009] As a further improvement of the present invention, the guide mechanism includes a vertically arranged guide rail, a guide slider is slidably connected to the guide rail, and the guide slider is connected to the base frame.

[0010] Compared with the prior art, the present invention has the following advantages:

[0011] When the maintenance port needs to be opened for maintenance, the switch of the second electric cylinder is operated, and the second electric cylinder drives the base frame to move upward a certain distance. Then, the first electric cylinder is operated, and the first electric cylinder drives the movable cover to flip downward to the inside of the base frame. At this time, the maintenance port is opened, and the pump station at the maintenance port can be maintained. After the maintenance is completed, the first electric cylinder is operated, and the first electric cylinder drives the movable cover to flip outward and open, and then the second electric cylinder is operated again, and the second electric cylinder drives the base frame to move downward to return to its original position. The degree of automation is high, and the maintenance port can be closed, reducing the trouble of manual opening. The setting of the base frame is not only used to support and connect the movable cover, but also the base frame and the movable cover form a whole, which improves stability and has a simple structure. In addition, the fence on the base frame can protect the safety of maintenance personnel at the maintenance port, reduce the risk of falling, and improve safety.

[0012] 2. By setting a guide mechanism between the basic frame and the maintenance port equipment, a certain guide can be provided for the up and down movement direction of the basic frame, thereby improving the lifting stability of the basic frame. BRIEF DESCRIPTION OF THE DRAWINGS
