[0032] Reference Figure 1 , 2 As shown, the automatic opening and closing manhole device according to an embodiment of the present invention includes a cylindrical cover 100, a rotating arm 200, a manhole cover 300, a first driving device 400, and a second driving device 500. The cylindrical cover 100 has a manhole neck ring 110, which is provided with a first rotating latching portion 120. One end of the rotating arm 200 is hinged to the cylindrical cover 100. The manhole cover 300 has a second rotating latching portion 310 and is rotatably mounted on the other end of the rotating arm 200. The first driving device 400 is used to drive the rotating arm 200 to rotate between a first position and a second position. Figure 2 As shown, in the first position, the manhole cover 300 can be mounted on the manhole collar 110; as Figure 1 As shown, in the second position, the manhole cover 300 is away from the manhole neck ring 110; the second drive device 500 is mounted on the rotating arm 200 and is used to drive the manhole cover 300 to rotate, so as to control the second rotating latching part 310 to latch or dislatch with the first rotating latching part 120.

[0033] One end of the rotating arm 200 is hinged to the cylinder cover 100, and the other end is connected to a rotatable manhole cover 300. The rotating arm 200 is also connected to a second driving device 500 for driving the manhole cover 300 to rotate. The manhole cover 300 can be rotatably engaged with the first rotating engagement part 120 of the manhole collar 110 via the second rotating engagement part 310, and the first driving device 500 can drive the rotating arm 200 to rotate. When it is necessary to open the manhole collar 110, the second driving device 500 drives the manhole cover 300 to rotate, causing the second rotating engagement part 310 to disengage from the first rotating engagement part 120, and then the first driving device 500... The first drive device 400 drives the rotating arm 200 to rotate from the first position to the second position, causing the manhole cover 300 to move away from the manhole neck ring 110. Conversely, the first drive device 400 drives the rotating arm 200 to rotate from the second position to the first position, so that the manhole cover 300 covers the manhole neck ring 110. Then, the second drive device 500 drives the manhole cover 300 to rotate, so that the second rotating locking part 310 engages with the first rotating locking part 120, thereby fixing the manhole cover 300 to the manhole neck ring 110. That is, the present invention only requires controlling the first drive device 400 and the second drive device 500 to open or close the manhole neck ring 110, which is labor-saving and time-saving.

[0034] In some embodiments of this utility model, such as Figure 2 As shown, the rotating arm 200 includes a vertical section 210 and a horizontal section 220. The vertical section 210 is located on one side of the manhole neck ring 110. The lower end of the vertical section 210 is hinged to the cylinder cover 100. One end of the horizontal section 220 is connected to the upper end of the vertical section 210. The manhole cover 300 is rotatably mounted on the other end of the horizontal section 220, so that the rotating arm 200 is L-shaped, so that the rotating arm 200 can better drive the manhole cover 300 to cover the manhole neck ring 110 or remove it from the manhole neck ring 110.

[0035] Specifically, the top of the manhole cover 300 is rotatably mounted to the bottom of the other end of the horizontal section 220.

[0036] In a further embodiment of this utility model, such as Figure 2 As shown, the first driving device 400 is a cylinder. The two ends of the first driving device 400 are respectively hinged to the lower side of the horizontal section 220 and the cylinder cover 100, and facilitate the rotation of the rotating arm 200. Specifically, a part of the cylinder can be located outside the rotating arm 200, or the first driving device 400 can be located between the vertical section 210 and the horizontal section 220 to utilize the space between the vertical section 210 and the horizontal section 220.

[0037] In a further embodiment of this utility model, such as Figure 1As shown, the manhole collar 110 has an outwardly extending support portion 130 on one side. One end of the first drive device 400 and one end of the rotating arm 200 are rotatably mounted on the support portion 130. By providing a straight support portion 130, the first drive device 400 can drive the rotating arm 200 to rotate more smoothly and make the rotating arm 200 rotate more smoothly.

[0038] Specifically, the fixed end of the cylinder is hinged to the support 130, and the extended end of the cylinder is hinged to the lower side of the horizontal section 220.

[0039] In a further embodiment of this utility model, such as Figure 2 As shown, the rotating arm 200 also includes a downwardly inclined section 230. One end of the inclined section 230 is fixedly connected to the other end of the horizontal section 220. The manhole cover 300 is rotatably mounted on the inclined section 230 to ensure that the manhole cover 300 can be opened smoothly.

[0040] In a further embodiment of this utility model, such as Figure 2 As shown, the other end of the rotating arm 200 is connected to a rotating shaft 240, and the manhole cover 300 is rotatably mounted on the rotating shaft 240 via a bearing, so that the rotation of the manhole cover 300 is smoother.

[0041] Specifically, the inclined section 230 is provided with a rotating shaft 240.

[0042] In a further embodiment of this utility model, such as Figure 2 As shown, the rotating shaft 240 is mounted on the other end of the rotating arm 200 by screws, which facilitates the installation and removal of the manhole cover 300.

[0043] In some embodiments of this utility model, such as Figure 1 As shown, the second driving device 500 is a cylinder. The two ends of the second driving device 500 are respectively hinged to the side wall of the rotating arm 200 and the manhole cover 300. This arrangement allows the second driving device 500 to drive the manhole cover 300 to rotate more smoothly.

[0044] Specifically, the fixed end of the cylinder is hinged to the rotating arm 200, and the extended end of the cylinder is hinged to the side wall of the manhole cover 300.

[0045] In some embodiments of this utility model, such as Figure 3 , 4 As shown, there are multiple first rotating latching parts 120 and multiple second rotating latching parts 310. Multiple first rotating latching parts 120 are spaced apart along the outer side wall of the manhole neck ring 110 and are disposed on the outer side wall of the manhole neck ring 110. The positions of multiple second rotating latching parts 310 correspond to the positions of multiple first rotating latching parts 120. Multiple second rotating latching parts 310 are disposed on the inner wall of the manhole cover 300.

[0046] The second drive unit 500 drives the manhole cover 300 to rotate between the third and fourth positions;

[0047] like Figure 5 As shown, when in the third position, the second rotating latching part 310 moves to the bottom of the first rotating latching part 120 and abuts against it, so that the second rotating latching part 310 and the first rotating latching part 120 are latched together, thereby preventing the manhole cover 300 from moving upward and fixing it to the manhole neck ring 110.

[0048] like Figure 6 As shown, when in the fourth position, the second rotating latching part 310 is located between two adjacent first rotating latching parts 120, so that the second rotating latching part 310 and the first rotating latching part 120 are disengaged from each other, and the first rotating latching part 120 does not block the second rotating latching part 310 from moving upward, so that the manhole cover 300 can be disengaged from the manhole neck ring 110.

[0049] Specifically, both the first rotating snap-fit ​​portion 120 and the second rotating snap-fit ​​portion 310 are wedges.

[0050] In some embodiments of this utility model, such as Figure 7 As shown, a sealing ring 111 is installed on the top of the manhole neck ring 110, and the manhole cover 300 can abut against the upper end face of the sealing ring 111 to ensure the sealing effect of the cylinder cover 100.
