[ detailed description ] of the invention
Referring to fig. 1, 2, 3 and 4, the composite anti-theft manhole cover of the present invention comprises a cover base 1, a cover body 2 and a pressing device 3, wherein the cover base 1 is a cylinder with a through hole 15 in the center, a plurality of ring grooves 11 parallel to the top surface are arranged on the inner wall of the through hole 15, vertical connecting grooves 12 are arranged between the ring grooves 11, a notch 14 communicated with the ring grooves 11 or the connecting grooves 12 is arranged on the side wall of the cover base 1, the cover body 2 comprises a circular cover body 21 and a plurality of protrusions 22 positioned at the edge of the cover body 21, the cover body 2 is positioned in the ring groove 11 at the uppermost layer of the cover base 1 when the manhole cover is closed, the pressing device 3 is positioned below the well cover base 1 and provides upward pressure for the cover body 2, the top surface of the cover body 21 is provided with an inward concave handle 211, the center of lid body 21 is equipped with pointer 212, the top surface of lid 1 is equipped with angle mark 13, the aperture of through-hole 15 is unanimous with the diameter of lid body 21, the inside diameter of annular 11 is unanimous with the centre of a circle of lid body 21 to the distance at protruding 22 edge, the height of annular 11 is unanimous with the height of lid body 21, the shape of spread groove 12 cross section is unanimous with protruding 22 cross section shape, roof pressure device 3 includes cylinder 31, controlling means 32, information receiver 33, telescopic link 34 and backup pad 35, controlling means 32 is connected with cylinder 31 and information receiver 33 electricity, the both ends of telescopic link 34 are connected with cylinder 31 and backup pad 35 respectively, the opposite side roof of backup pad 35 pushes down the bottom surface of lid body 21.
The working process of the invention comprises the following steps:
firstly, the cover 1 is installed in a well, and a notch corresponding to the notch 14 is arranged on the well wall for plugging the cover 2. When the well lid needs to be opened, firstly, the information of the cover opening is transmitted to the control device 32 through the information receiver 33, so that the control cylinder 31 drives the telescopic rod 34 to retract, and the supporting plate 35 does not press against the bottom surface of the cover body 21. The handle 211 is then held, and the cover 2 is rotated in the ring groove 11 of the first layer by a certain angle, so that the protrusions 22 are aligned with the connection grooves 12, thereby allowing the cover 2 to drop into the ring groove 11 of the next layer. This is repeated until the cover 2 falls down onto the ring groove 11 or the connecting groove 12 at the same level as the notch 14, and the cover 2 is horizontally moved so that the cover 2 is separated from the base 1 from the notch 14 and enters a preset notch in the well. When the well lid needs to be closed, the cover body 2 is translated back into the cover base 1 from the notch and is put back into the annular groove 11 of the first layer by layer. In the process, the pointer 212 and the angle mark 13 can assist personnel in knowing the rotating angle of the cover body 2 in the cover base 1, so that the cover body 2 can be moved out of the labyrinth groove channel in the cover base 1 more quickly. After the well cover is closed, the supporting plate 35 is pushed upwards by the air cylinder 31 to press the cover body 2.
According to the invention, the labyrinth groove channel is formed by arranging the plurality of parallel ring grooves and the vertical connecting grooves in the cover base, so that people can quickly move the cover body into the notch of the well wall from the notch of the cover base according to the designated route according to the pointer and the angle mark, and the well cover is opened; the cover body cannot be taken out from the upper opening and the lower opening of the cover base, so that the cover body is prevented from being stolen; the cover body is provided with an upward acting force through the jacking device, so that a thief cannot directly rotate or press down the cover body to leave the labyrinth groove channel, and meanwhile, the edge of the annular groove is abutted against the bulge, so that the device is prevented from being damaged due to the fact that the force pressed down by the thief directly acts on the jacking device.
The above embodiments are illustrative of the present invention, and not limiting, and any simple modifications of the present invention fall within the scope of the present invention.
