The manhole cover 1 and the manhole frame 2 are sealed together. A hinge 3 is symmetrically and movably connected between one side of the manhole cover 1 and the manhole frame 2. A support frame 11 is fixedly installed on the bottom surface of the manhole cover 1 to increase the overall strength of the manhole cover 1. A high-transparency glass 12 is fixedly installed in the middle of the support frame 11. A slot 13 is opened on the surface of the manhole cover 1. The slot 13 is perpendicular to the high-transparency glass 12. A groove 14 is opened on both sides of the slot 13. A support strip 15 is slidably installed inside the slot 13. A cover plate 4 is engaged inside the slot 13. The bottom surface of the cover plate 4 is in contact with the top surface of the support strip 15. A lock seat 5 is fixedly installed on one side of the manhole frame 2 between the hinges 3.

[0023] The device can facilitate observation and self-locking of the cover plate in actual application. The cover plate 4 is arranged on the top of the manhole cover 1 in normal state. The cover plate 4 can be taken out by twisting the vertical column 41 to make the lock bar 42 disengage from the strip groove 14. Then, the support strip 15 is taken out, and the inside of the pipe gallery is observed through the high-transparency glass 12. When the manhole cover 1 is opened, the buckle 16 is rotated together. When the buckle 16 rotates, the lock block 53 is pressed into the lock groove 51. Then, the position of the buckle 16 is limited by the lock block 53, so that the self-locking effect is achieved, and the cover plate cannot be suddenly covered due to falling off and the like.

[0024] Please refer to Figs. 1-3 The inside of the cover plate 4 is symmetrically rotatably provided with the vertical column 41. A slit is formed at the top of the vertical column 41. A flathead screwdriver can be used to twist the direction of the vertical column 41. The inside of the cover plate 4 is provided with a receiving groove. The bottom of the vertical column 41 is fixedly connected with the lock bar 42 in the receiving groove. The position of the receiving groove corresponds to the position of the strip groove 14. The end of the lock bar 42 is matched with the shape of the inside of the strip groove 14.

[0025] The flathead screwdriver can be used to twist the rotating position of the vertical column 41. When observation is needed, the flathead screwdriver is used to twist the vertical column 41, so that the lock bar 42 disengages from the shape limitation of the strip groove 14. Then, the cover plate 4 is taken out, and the support strip 15 is taken out, so that the top of the high-transparency glass 12 is not interfered by objects. The worker looks into the inside of the pipe gallery through the high-transparency glass 12, and can observe the inside of the pipe gallery. If the inside needs to be maintained, the manhole cover 1 is opened for maintenance. If the maintenance is not needed, the cover plate 4 is covered, which facilitates the worker to observe whether the inside of the pipe gallery needs to be maintained.

[0026] Please refer to Figs. 1-4 One side of the manhole cover 1 is fixedly provided with the buckle 16 between the hinges 3. The inside of the buckle 16 is provided with a cross bar.

The size between the lock groove 51 and the buckle 16 is matched.

[0027] When the manhole cover 1 is opened, the buckle 16 rotates together. The buckle 16 is clamped into the inside of the lock groove 51. When the cross bar is in contact with the top inclined surface of the lock block 53, the lock block 53 is pushed outward. After the manhole cover 1 is completely opened, the buckle 16 is rotated by 90°, so that the cross bar is completely clamped into the inside of the lock groove 51. The lock block 53 returns to the original position due to the pulling force of the spring 55, and limits the position of the buckle 16, so that the position of the manhole cover 1 cannot be rotated, and the limiting operation is achieved.

[0028] Please refer to Figs. 1-4The inside of the lock seat 5 is rotatably installed with a rotating column 52, the outer ring of the rotating column 52 is fixedly installed with a lock block 53, the top surface of the lock block 53 is inclined, the lock block 53 completely covers the cross section of the lock slot 51 at the top, the back of the lock block 53 is fixedly installed with an unlocking plate 54 at one side of the lock seat 5, and the unlocking plate 54 is fixedly connected with springs 55 between the two sides and the lock seat 5.

[0029] After the position of the buckle 16 is limited by the lock seat 5, the lock block 53 is driven to rotate outward by pulling the unlocking plate 54, so that the lock slot 51 is unblocked, then when the manhole cover 1 is closed, the position of the buckle 16 is no longer limited by the lock block 53 and can be moved, the unlocking plate 54 needs to be manually operated by the worker after climbing out of the pipe gallery after entering the pipe gallery for maintenance, so as to avoid injury caused by the sudden sliding of the manhole cover 1 when the worker is working inside the pipe gallery.

[0030] Working principle: When the device is used, the worker first needs to check the inside of the pipe gallery, twists the vertical column 41 by using a screwdriver to make the lock bar 42 disengage from the shape limitation of the strip slot 14, then takes out the cover plate 4, and then takes out the supporting strip 15, so that the top of the high-transparency glass 12 is not disturbed by objects, the worker looks into the pipe gallery through the high-transparency glass 12, can observe the inside of the pipe gallery, and after observation, if maintenance is needed, the manhole cover 1 is opened, the buckle 16 is driven to rotate together when the manhole cover 1 is opened, the buckle 16 is rotated and clamped into the inside of the lock slot 51, because the shape of the horizontal rod contacts the inclined top of the lock block 53, the lock block 53 is pushed outward, after the manhole cover 1 is completely opened, the buckle 16 is rotated by 90°, so that the horizontal rod is completely clamped into the inside of the lock slot 51, the lock block 53 returns to the original position due to the pulling force of the spring 55, and the position of the buckle 16 is limited, at this time the worker can enter the pipe gallery for maintenance, and after maintenance is completed, the worker climbs out of the pipe gallery, pulls the unlocking plate 54 to drive the lock block 53 to rotate outward, so that the buckle 16 is no longer limited by the lock block 53, the lock slot 51 is unblocked, then the manhole cover 1 is closed, the buckle 16 is slid out of the inside of the lock slot 51, and the self-locking effect of the manhole cover 1 is realized.
