[0018] Reference Figure 1 , Figure 2The pipe gallery cover includes an electric control device (not shown in the figure), a base 1, and a cover 2. A rotating shaft 3 is arranged between the cover 2 and the base 1. A cover driving device 5 is arranged between the base 1 and the cover 2. The cover 2 can be rotated around the rotating shaft 3 by the cover driving device 5 to open or close the base 1. A lock catch 21 is movably connected to the lower side of the cover 2. A bracket 11 is fixedly arranged below the lock catch 21. A lock driving device 6 is arranged on the bracket 11. The lock driving device 6 is connected to a lock pin 61. The lock pin 61 can be moved upward to form a first state or moved downward to form a second state by the lock driving device 6.

[0019] When the cover 2 is closed with the base 1, the lock pin 61 in the first state is connected and matched with the lock catch 21 to fix and position the cover 2 and the base 1. This state is suitable for the daily state of non-maintenance. The cover 2 can be prevented from being accidentally opened in daily use. When the cover 2 needs to be opened, the worker needs to first separate the lock catch 21 from the lock pin 61, then open the cover 2 by hand or the cover driving device 5, and then adjust the lock pin 61 to the second state by the lock driving device 6.

[0020] The lock pin 61 in the second state is separated from the lock catch 21 to allow the cover 2 to freely open the base 1. The lock pin 61 in the second state does not affect the lock catch 21. Therefore, after the lock pin 61 enters the second state, the cover 2 can be continuously opened relatively quickly by hand or the cover driving device 5, which facilitates the worker to enter and exit the pipe gallery for maintenance multiple times.

[0021] The electric control device is electrically connected with the cover driving device 5 and the lock driving device 6.

[0023] The reset member can push the lock catch 21 to maintain the connection and matching with the lock pin 61, so that the lock catch 21 can be automatically locked and fixed with the lock pin 61 when the cover 2 is closed in the first state.

[0024] Further, the face cover 2 is provided with a lock head 4 capable of being connected and matched with an external key, a connecting rod assembly is arranged between the lock head 4 and the lock catch 21, the connecting rod assembly comprises a first connecting rod 41, a second connecting rod 42 and a third connecting rod 43, the first end of the first connecting rod 41 is fixedly connected with the lock head 4, the tail end of the first connecting rod 41 is fixedly connected with the first end of the second connecting rod 42, the tail end of the second connecting rod 42 is fixedly connected with the first end of the third connecting rod 43, and the tail end of the third connecting rod 43 is connected and matched with the lock catch 21, the lock head 4 can drive the first connecting rod 41, the second connecting rod 42 and the third connecting rod 43 to swing in sequence when being rotated in the positive direction, so that the tail end of the third connecting rod 43 pushes the lock catch 21 to be separated from the lock pin 61, and the user can drive the lock catch 21 to be separated from the lock pin 61 by the key corresponding to the lock head 4 from the outside of the face cover 2, so that the face cover 2 can be opened from the outside.

[0025] Further, the cover driving device 5 comprises a cylinder body 51 and a piston rod 52, the cylinder body 51 is movably connected with the base 1, the first end of the piston rod 52 is movably connected with the face cover 2, the cylinder body 51 can drive the piston rod 52 to extend outward to open the base 1 or the cylinder body 51 can drive the piston rod 52 to be accommodated inward to close the base 1, when the piston rod 52 extends outward, the cylinder body 51 will be rotated upward around the position connected with the base 1 under the action of the reverse thrust, so as to realize the lifting of the face cover 2, and the effect of opening the base 1 by the face cover 2.

[0026] Further, the position adjacent to the face cover 2 of the base 1 is provided with an infrared photoelectric detection device (not marked in the figure), the infrared photoelectric detection device is electrically connected with an electric control device, the electric control device is further electrically connected with an alarm device, the condition of the entry of personnel or foreign matters can be monitored, the electric control device feeds back the monitoring condition to a monitoring background, so as to facilitate the monitoring of the well cover by the staff. The monitoring condition can be fed back to the monitoring background through the electric control device by different ways such as storage collection or wireless transmission.

[0027] Further, the cover driving device 5 is connected with a pressure sensing device (not marked in the figure), the pressure sensing device is electrically connected with the electric control device, when the pressure sensing device detects that the pressure value is greater than the preset range when the face cover 2 is closed, the electric control device judges that it is abnormal, and the cover driving device 5 can be controlled to stop working to avoid the injury of the worker. At the same time, the alarm device can also send an alarm to the outside.
