[0015] In the present application, during specific use, the buried seat is buried underground, and the top of the cover body and the base are flush with the ground. When the cover body needs to be opened, the protective plate is first pried up and taken out by a tool such as a crowbar, and then the handle is pulled to rotate the rotating plate. Then the sliding plate can be pulled to one side through the rotating plate, and the sliding plate drives the card plate to move it out of the bottom of the cover plate. At this time, since the rectangular part of the cover plate is heavier than the arc-shaped part, and the rotation point is located at the center of the cover plate, the cover plate will rotate to one side of the card plate and tilt to a vertical state. Then, a crowbar or other tool is used to hook the through hole to move the cover body along the slide groove, so that the cover body is moved to one side to open it for easy entry for staff. The roller connected to the outer wall of the shaft can reduce friction and reduce the force used.
[0016] In the utility model, the light-weight and convenient-to-open and -maintenance electric manhole cover can achieve the effect of opening the manhole cover by rotating it and pulling it aside when it is needed to be opened for maintenance and other operations, thereby avoiding the traditional phenomenon of manually prying up the entire manhole cover and then moving it, and thus opening it in a lighter way;
[0017] In the utility model, the light-weight and convenient-to-open and -maintenance electric manhole cover can achieve that under normal circumstances, the cover body can be stably arranged inside the frame body through the locking assembly, thereby ensuring normal use. When it is necessary to open the cover, the cover plate can be released from its fixed state and turned over by simply pulling the card plate to one side through the handle, and then it can be pulled aside to achieve the opening effect.
[0018] In the utility model, when in use, the buried seat is buried underground so that the top of the base and the cover plate are flush with the ground to complete the installation. When it is necessary to open for maintenance and other operations, it is only necessary to pull the handle to release the locking and limiting effect of the locking component on the cover plate, and then the cover plate will rotate and move to one side to complete the opening;
[0019] This avoids the traditional operation of lifting and moving the entire manhole cover, thereby achieving a lighter and more labor-saving effect. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0025] Example 1
[0026] Reference Figure 1-3 A light-weight electric manhole cover which is convenient to open and repair is used in the field of electric manhole covers and comprises: a frame 1, a cover 2 and a locking assembly.
[0027] Reference Figure 2 The frame 1 includes a base 4 and a buried seat 3. The base 4 is designed to have an arc-shaped inner side and a rectangular structure on the other side. A pair of slide grooves 6 are provided on both sides of the rectangular inner wall of the base 4 for sliding connection of the cover 2. In addition, an arc-shaped bottom plate 5 is fixedly provided at the bottom of the inner wall of the base 4 on one side of the arc. The arc-shaped bottom plate 5 is located below the cover plate 10 and is used to support the cover 2 when it is closed.
[0028] The cover body 2 includes a cover plate 10 and a through hole 12 formed on the surface of the cover plate 10 for ventilation. Connecting shafts 9 are fixedly disposed on both sides of the cover plate 10. The two connecting shafts 9 extend to the inside of the slide groove 6 of the base 4, respectively, so that the cover body 2 can slide smoothly along the slide groove 6. The outer wall of the connecting shaft 9 is also rotatably sleeved with a roller 11 to reduce sliding friction and improve the smoothness of opening and closing.
[0029] Reference Figure 3 The locking assembly is arranged inside the base 4, and is used to limit and lock the cover body 2. The assembly includes a card plate 7, a sliding plate 13, a rotating plate 16 and a vertical plate 15. A cavity 14 is provided on the top of the base 4 near the rectangular side, and the sliding plate 13 is slidably arranged inside the cavity 14. The card plate 7 is fixed to the bottom of the sliding plate 13 near the cover plate 10, and one end thereof slides through the bottom of the cover plate 10 to achieve the locking function. The rotating plate 16 is rotatably arranged on the top of the sliding plate 13, and the vertical plate 15 is fixedly arranged on the inner wall of the cavity 14 away from the sliding plate 13, and is located below the rotating plate 16 to support the rotating plate 16 and prevent it from excessive rotation. A groove 18 is provided on the top of the rotating plate 16, and a handle 17 is fixedly arranged inside the groove 18 to facilitate the operation of the operator.
[0030] Specifically, the buried seat 3 is buried underground, and the tops of the cover body 2 and the base 4 are flush with the ground. When the cover body 2 needs to be opened, the handle 17 is pulled to rotate the rotating plate 16, and then the sliding plate 13 can be pulled to one side through the rotating plate 16, and the sliding plate 13 drives the card plate 7 to move and make it detach from the bottom of the cover plate 10. At this time, since the rectangular part of the cover plate 10 is heavier than the arc-shaped part, and the rotation point is located at the center of the cover plate 10, the cover plate 10 will rotate to one side of the card plate 7 and tilt to a vertical state. Then, a crowbar or other tool is used to hook the through hole 12 to move the cover body 2 along the slide groove 6, so that the cover body 2 is moved to one side to open it for the staff to enter. The roller 11 connected to the outer wall of the shaft 9 can reduce friction and the force used, thereby avoiding the traditional operation of prying up the entire manhole cover and moving it away, so as to achieve a lighter and more labor-saving effect.
