The movable seat 61 moves backwards, and can drive the turnover connecting structure 65, so that the well lid 2 is turned outwards relative to the well frame 1, and the well lid 2 is opened. When the well lid 2 needs to be closed, the rotation driving device 3 is started to rotate reversely, so that the transmission shaft 4 is driven to rotate reversely. The reverse rotation of the transmission shaft 4 drives the moving seat 61 to move forward, so that the well lid 2 is turned inwards relative to the well frame 1, until the moving seat 61 and the clutch triggering structure are triggered, the well lid 2 is completely closed, and the clutch triggering structure enables the transmission shaft 4 and the moving seat 61 to be separated in a transmission manner, so that the moving seat 61 stops moving; meanwhile, the transmission shaft 4 is in transmission connection with the connection seat 51 after the moving seat 61 is separated, so as to drive the connection seat 51 to move forward. The connecting block 51 is moved forward so that the locking device 5 is in locking connection with the well frame 1, thereby entering a locked state. It should be noted that, in this embodiment, the forward rotation of the transmission shaft 4 drives the movable seat 61 and the connecting seat 51 to move backward, and the reverse rotation of the transmission shaft 4 drives the movable seat 61 and the connecting seat 51 to move forward, in other embodiments, the forward rotation and the reverse rotation of the transmission shaft 4 can drive the movable seat 61 and the connecting seat 51 to move in other directions. Therefore, the invention controls the transmission shaft 4 to be in transmission connection with the movable seat 61 or the connecting seat 51 through the clutch triggering structure, so that the locking or unlocking and the opening or closing of the well lid 2 are sequentially carried out, the locking device 5 and the well lid 2 overturning device 6 are continuous in operation, and the operation is simple, convenient, safe and reliable.
Further, the clutch triggering structure includes a sliding clutch, a flexible clutch 42 and a first triggering assembly 43; the sliding clutch comprises a threaded sleeve 411, and the sliding clutch is in transmission connection with the connecting seat 51 through the threaded sleeve 411; the locking end of the transmission shaft 4 is provided with a thread part 40 corresponding to the thread sleeve 411; the threaded sleeve 411 is matched and connected with the threaded part 40 and sleeved on the transmission shaft 4; the connecting seat 51 is provided with a second triggering assembly 510, and the second triggering assembly 510 is used for fixing the threaded sleeve 411 and the connecting seat 51 into a whole or enabling the threaded sleeve 411 to rotate relative to the connecting seat 51; the well lid 2 overturning device 6 comprises a connecting shaft 62, the moving seat 61 is in transmission connection with the connecting shaft 62, and the well lid 2 overturning device 6 drives the moving seat 61 to move through the rotation of the connecting shaft 62; the elastic clutch 42 comprises a first clutch seat 421, a second clutch seat 422, a push rod 424 and an elastic member 423, the elastic member 423 is installed between the first clutch seat 421 and the second clutch seat 422, and the elastic member 423 separates the first clutch seat 421 from the second clutch seat 422 through elastic force; one end of the push rod 424 is fixedly connected with the first clutch seat 421, the other end of the push rod extends along the direction of the locking end, and when the push rod 424 is acted by external force, the first clutch seat 421 is connected with the second clutch seat 422; the first clutch seat 421 is installed on the turning end of the transmission shaft 4, and the second clutch seat 422 is installed on the connecting shaft 62; the first trigger assembly 43 comprises a trigger baffle 431 and a catch 432; when the transmission shaft 4 rotates forward to drive the connecting seat 51 to move, and when the second trigger assembly 510 and the trigger baffle 431 trigger, the connecting seat 51 is pressed on the push rod, and the threaded sleeve 411 is separated from the second trigger assembly 510, so that the threaded sleeve 411 rotates relative to the connecting seat 51; when the transmission shaft 4 reversely drives the movable base 61 to move, when the movable base 61 is clamped and connected by the clamping piece 432, the second trigger piece is separated from the trigger baffle 431, the connecting base 51 is separated from the push rod, and meanwhile, the threaded sleeve 411 is connected with the second trigger assembly 510, so that the threaded sleeve 411 and the connecting base 51 are fixedly positioned into a whole.
Specifically, in this embodiment, as shown in fig. 2 to 5, when the well lid 2 is locked, the connecting seat 51 is inserted into the slot through the inserting element 512, and is fixed to the threaded sleeve 411. When the well lid 2 needs to be opened, the rotation driving device 3 drives the transmission shaft 4 to rotate forward, so that the threaded sleeve 411 moves backward, and the threaded sleeve 411 and the connecting seat 51 are fixed into a whole at the moment, so that the movement of the threaded sleeve 411 can drive the connecting seat 51 to move in the same direction, and the locking device 5 is enabled to unlock the movable seat. When the threaded sleeve 411 drives the connecting seat 51 to move backward until the triggering positioning element 511 and the triggering baffle 431 trigger, the locking device 5 is in a complete unlocking state. When the triggering positioning element 511 and the triggering baffle 431 are triggered, an acting force exists, and the acting force pushes the triggering positioning element 511 to slide forwards on the connecting seat 51. The connecting seat 51 slides forward, which in turn causes the protruding sliding portion 5121 clamped in the sliding groove 5111 to slide upward, thereby causing the inserting element 512 to move upward. The upward movement of the inserting element 512 causes the inserting end to be pulled out from the engaging slot and clamped in the inserting gap 41110, so that the connecting seat 51 is separated from the threaded sleeve 411, and the sliding of the connecting seat 51 is stopped. Because the threaded sleeve 411 is sleeved on the transmission shaft 4, the threaded sleeve tends to move backwards when the transmission shaft rotates forwards. However, the insertion element 512 is limited to the insertion gap 41110, so that the threaded sleeve 411 cannot move and can only idle in the connecting seat 51. It should be noted that the triggering positioning member 511 is disposed parallel to the transmission shaft 4 for precisely triggering the triggering baffle 431.
After the trigger positioning element 511 and the trigger baffle 431 are triggered, the hook portion 4321 of the engaging element 432 hooks the locking surface of the connecting seat 51, that is, the front side surface of the connecting seat 51 in this embodiment, such an arrangement is that there is always an action between the trigger positioning element 511 and the trigger baffle 431, so that the inserting element 512 is connected in the inserting gap 41110 in a limiting manner, thereby ensuring that the threaded sleeve 411 and the connecting seat 51 are in a separated state. After the hook portion 4321 hooks the locking surface of the connecting seat 51, the inserting portion 4322 is disengaged from the connecting hole 610. In addition, during the triggering process of the triggering positioning element 511 and the triggering baffle 431, the connecting seat 51 pushes the push rod 424 to move backwards. The push rod 424 moves backwards, and pushes the first clutch seat 421 to move backwards, so that the first clutch seat 421 is connected with the second clutch seat 422, and the transmission shaft 4 is in transmission connection with the connection shaft 62 through the elastic clutch 42 and drives the connection shaft 62 to rotate forwards. The connecting shaft 62 rotates forward to drive the moving seat 61 to slide backward, so that the well lid 2 is turned over outwards relative to the well frame 1 to be opened.
When the well lid 2 is closed, the rotation driving device 3 drives the transmission shaft 4 to rotate reversely, and the connecting shaft 62 also rotates reversely, so that the moving seat 61 moves forwards. When the moving seat 61 moves forward to the connection hole 610 to connect with the insertion part 4322, the manhole cover 2 is in a completely closed state. When the connection hole 610 is connected to the insertion portion 4322, the hook portion 4321 is disengaged from the locking surface, and the transmission shaft 4 rotates reversely to drive the threaded sleeve 411 to move forward, so that the force between the trigger positioning member 511 and the trigger baffle 431 disappears.
