The cover plate 1 is located on a side of the support plate 2 close to the cover plate 5. A top column 24 is fixedly installed between the cover plate 1 and the support plate 2. The support plate 2 and the cover plate 1 are connected by the top column 24. An annular sinking groove 11 is opened on the cover plate 1. The annular sinking groove 11 is coaxially arranged with the cover plate 5. A sliding plate 53 is slidably installed in the annular sinking groove 11. Side plates 53 are fixedly installed on both sides of the sliding plate 53. The cover plate 5 is provided with a rotating seat 55, and a fixed shaft 51 is fixedly installed on the rotating seat 55. The two ends of the fixed shaft 51 are rotatably connected with the side plate 52. The cover plate 5 is provided with a plurality of threaded holes on the side away from the sliding plate 53. The cover plate 1 is also provided with threaded holes. The threaded holes are provided with screws 57. The end of the screw 57 close to the cover plate 5 is fixedly provided with a bolt head 54. The bolt head 54 is provided with a countersunk hole 56. The countersunk hole 56 is a positive hole. Deformation, a rotating ring 8 is rotatably installed between the cover plate 1 and the support plate 2, a plurality of notches 91 are opened on the circumference of the rotating ring 8, a plurality of driving grooves 25 are opened on the circumference of the support plate 2, a plurality of sliding columns 103 are slidably installed on the driving groove 25, one end of the sliding column 103 is located in the notch 91, and the other end of the sliding column 103 is located in the driving groove 25, a mounting plate 102 is fixedly installed at the middle end of the sliding column 103, and a sealing plate 10 is fixedly installed at one end of the mounting plate 102, the A third spring 104 is installed in the horizontal direction between the support plate 2 and the sliding column 103, a push rod 6 is slidably installed on the support plate 2, one end of the push rod 6 is in contact with the rotating ring 8, and a third wedge block 61 is installed on the other end of the push rod 6, a second sliding rod 4 is provided on one side of the third wedge block 61, a second sliding rod 4 is fixedly installed with a second wedge block 41 corresponding to the third wedge block 61, the second sliding rod 4 is slidably connected to the support plate 2, and a monitoring camera 12 is fixedly installed on the support plate 2.

[0024] In this embodiment, a third spring 104 is installed between the top column 24 and the mounting plate 102. The countersunk hole 56 can adopt different patterns as the structure of the countersunk hole 56 for manhole covers of different uses, thereby avoiding accidental opening of the manhole cover. At the same time, the complex shape can also increase the difficulty of opening by external force.

[0025] When normally maintaining the power and gas pipelines installed in the pipeline, the worker first holds a wrench with the same shape as the countersunk hole 56, inserts the wrench into the countersunk hole 56, and then rotates it. After the rotation, the screw rod 57 gradually separates from the cover plate 1, and then the cover plate 5 is rotated. After a certain angle, the sliding plate 53 and the cover plate 5 are driven to move toward the annular sinking groove 11 until they move to the end point, and then the cover plate 5 is turned over so that the cover plate 5 is completely placed on the ground. At this time, since the bolt head 54 is not separated from the cover plate 5, it is only separated from the cover plate 5. The cover plate 1 is detached, so one end of the bolt head 54 is completely extended out of the cover plate 5. When the cover plate 5 contacts the ground, the bolt head 54 extending out of the cover plate 5 will squeeze the second sliding rod 4. The second sliding rod 4 pushes the push rod 6 to move under the action of the second wedge block 41. One end of the push rod 6 abuts against the rotating ring 8, thereby pushing the rotating ring 8 to rotate. The rotation of the rotating ring 8 drives the sliding column 103 to move, so that a plurality of sealing plates 10 can be moved outward, thereby presenting a state of opening the channel. At this time, the staff can be secured by a safety rope The rope is lowered, and a receiving hole for the rope to pass through is left at the intersection of the several sealing plates 10. During the work, the staff needs to ventilate but avoid the situation where foreign objects fall or uninformed personnel step on and fall when the manhole cover is opened. At this time, when the staff has fully entered, lift the cover plate 5, and then rotate it in the opposite direction at a small angle, so that the bolt head 54 is disengaged from the first sliding rod 3. At this time, the first sliding rod 3 returns to its original position under the action of the third spring 104, and the sealing plates 10 will also gather together at the same time, thereby closing the passage opening. Therefore, it can avoid the situation where people or foreign objects fall during the maintenance process, thereby improving the safety of external personnel and also improving the safety of personnel working under the pipeline; in addition, by providing a monitoring camera 12, several monitoring cameras 12 can be connected to the monitoring room through the Internet of Things technology, so that the underground pipeline situation can be monitored, and timely rescue can be provided in case of personnel falling. Secondly, the working situation of the staff in the underground pipeline can be supervised, including personnel situation and working time.

[0026] In the present embodiment, screws 57 and the like are provided on the manhole cover to fix the manhole cover to prevent the manhole cover from shifting when a car passes by, etc. Secondly, a countersunk hole 56 of a specific shape is provided to break the conventional shape of the countersunk hole 56, thereby preventing non-maintenance personnel from opening the manhole cover. Secondly, the sealing plate 10 can be opened by pre-burying a second sliding rod 4 in the ground, and the state of the sealing plate 10 can be switched by the slidingly connected sliding plate 53, thereby preventing people from falling while the staff are working.

[0027] See also Figure 4 , Figure 5 In one embodiment, it also includes a sliding frame 7 and a first sliding rod 3. The sliding frame 7 is open and slidably connected to the support plate 2. The support plate 2 and the sliding frame 7 are horizontally installed with a second spring 72. A fourth wedge block 71 is fixedly installed at one end of the sliding frame 7 away from the support plate 2. The first sliding rod 3 is slidably connected to the support plate 2. A first wedge block 31 corresponding to the fourth wedge block 71 is installed on the first sliding rod 3.

[0028] In this embodiment, a second spring 72 is installed between the top column 24 and the sliding frame 7 , a first connecting plate 21 is fixedly installed on the support rod, and the first sliding rod 3 is slidably connected to the first connecting plate 21 .

[0029] When non-maintenance personnel open the manhole cover, they only flip the manhole cover to the ground. At this time, the cover plate 5 is completely placed on the ground, and the bolt head 54 extending out of the cover plate 5 will squeeze the first sliding rod 3. The first sliding rod 3 pushes the sliding frame 7 to move under the action of the first wedge block 31 until the sliding frame 7 pushes the mounting plate 102. By pressurizing the mounting plate 102, it is equivalent to applying additional pressure between several sealing plates 10. The additional pressure brings greater friction, thereby preventing the sealing plate 10 from breaking due to the falling of foreign objects. At the same time, it can also provide greater supporting force when people step on it. Secondly, when the manhole cover is opened by non-maintenance personnel, the sealing plate 10 can be kept closed, which can prevent the sealing plate 10 from being opened under the action of external force, thereby avoiding serious safety accidents. When non-maintenance personnel need to close the manhole cover, they rotate the manhole cover to disengage the bolt head 54 from the first sliding rod 3. At this time, the sliding frame 7 returns to its original position under the action of the second spring 72.

[0030] See also Figure 4 , Figure 5 In one embodiment, a second connecting plate 22 is fixedly mounted on the support plate 2, a first spring 42 is connected between the second connecting plate 22 and the second sliding rod 4, a fixing plate 23 is fixedly mounted on the second connecting plate 22, and the second sliding rod 4 passes through the fixing plate 23 and is slidably connected to the fixing plate 23.

[0031] In this embodiment, by providing a fixing plate 23, the sliding of the second sliding rod 4 can be made more stable. In addition, by providing a first spring 42, when the bolt head 54 is detached from the second sliding rod 4, it can be restored to its original position in time to prevent the push rod 6 from blocking the rotation of the rotating ring 8.

[0032] See also Figure 4In one embodiment, a plurality of swing rods 9 are fixedly mounted on the rotating ring 8 , and a slot 91 is formed on the swing rods 9 .

[0033] In this embodiment, the swing rod 9 is arc-shaped.

[0034] See also Figures 4 to 7 In one embodiment, a plurality of through grooves 101 are formed on the sealing plate 10 .

[0035] In this embodiment, by opening a plurality of through grooves 101 on the sealing plate 10, foreign objects can be blocked and filtered when the manhole cover is opened, and secondly, a ventilation passage can be provided when the staff is working.

[0036] See also Figure 6 In one embodiment, the sealing plate 10 is in the shape of an equilateral triangle.

[0037] In this embodiment, the regular triangle structure can provide better stability to the structure after the sealing plate 10 is closed.

[0038] See also Figure 6 In one embodiment, a first inclined surface 105 and a second inclined surface 106 are provided on the sealing plate 10 at both sides of the sliding column 103 , and the first inclined surface 105 and the second inclined surface 106 have opposite inclination directions.

[0039] In this embodiment, by setting the two sides of the sealing plate 10 to have a slope effect, a stacked support effect is formed on the plurality of sealing plates 10, that is, the slope on one side of a single sealing plate 10 forms a slope support effect for the adjacent sealing plate 10, and the slope on the other side of the single sealing plate 10 is in contact with the adjacent sealing plate 10, and the slopes of the adjacent sealing plates 10 provide support.

[0040] Through the support of the two inclined surfaces, firstly, the contact area between the side surfaces of the sealing plate 10 is increased, and secondly, lateral friction and vertical friction can be formed, thereby increasing the friction, and at the same time, a mutually supporting stacking effect can be formed, thereby providing greater supporting force.
