A real-time monitoring and early warning anti-sinking manhole cover

Abstract

The utility model discloses an anti-sinking manhole cover with real-time monitoring and early warning, comprising a manhole cover and a manhole seat, wherein a mounting hole for placing the manhole cover is opened at the top of the manhole seat, and an extrusion block for transmitting the pressure of the manhole cover is installed at the bottom of the manhole cover, and the extrusion block is arranged in close contact with the inner wall of the manhole seat. When a car or other large gravity presses down the manhole cover, four extrusion blocks are driven to squeeze the inner wall of the manhole seat through the connection of a transmission rod, and the downward pressure of the manhole cover is transmitted to the extrusion force of the extrusion blocks on the manhole seat, thereby reducing the squeezing of the manhole cover on the top of the manhole seat, preventing damage to the top of the manhole seat, and further preventing the well seat from being damaged and causing the manhole cover to sink. When the manhole cover is pressed down, the extrusion rod at the bottom of the manhole cover will slide inside the storage hole, and the downward pressure of the manhole cover will be buffered by the action of the spring, further preventing the manhole cover from squeezing the top of the well seat and damaging it to cause the manhole cover to sink. At the same time, the downward movement of the manhole cover can be buffered to reduce the noise of the manhole cover movement.

Description

Technical Field

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] The utility model provides a technical solution: Figures 1 to 4 As shown, in the present embodiment, a real-time monitoring and early warning anti-subsidence manhole cover comprises a manhole cover 1 and a manhole seat 2, the top of the manhole seat 2 is provided with a mounting hole 3 for placing the manhole cover 1, the bottom of the manhole cover 1 is provided with an extrusion block 4 for transmitting the pressure of the manhole cover 1, the extrusion block 4 is arranged in contact with the inner wall of the manhole seat 2, and the extrusion block 4 is extruded with the manhole seat 2, a spring 5 for alleviating the downward pressure of the manhole cover 1 is installed on the top of the manhole seat 2, the spring 5 is arranged in a ring array with the central axis of the manhole seat 2 as the axis, a water inlet hole 6 is provided in the middle of the manhole cover 1, and a water level monitor 7 for detecting the water level is installed below the manhole cover 1, the water level monitor 7 transmits signals with the water conservancy department through lines, and can detect the water level of the water body or sewage inside the manhole seat 2 to prevent the accumulation of water inside the manhole seat 2 from causing blockage of the sewer.

[0022] like Figures 1 to 4 As shown, a first mounting block 8 is fixedly installed at the bottom of the manhole cover 1 in a ring array with the central axis of the manhole cover 1 as the axis, a transfer rod 9 is rotatably installed at the middle of the first mounting block 8 through an axle pin, and a second mounting block 10 is fixedly installed on the inner side of the extrusion block 4, and the end of the transfer rod 9 away from the first mounting block 8 is rotatably connected to the second mounting block 10 by an axle pin.

[0023] The downward pressure of the manhole cover 1 will drive the transfer rod 9 to move downward, and through the connection of the transfer rod 9, the four extrusion blocks 4 will be driven to squeeze the inner wall of the well seat 2, and the downward pressure of the manhole cover 1 will be transmitted to the extrusion force of the extrusion blocks 4 on the well seat 2, thereby reducing the extrusion of the manhole cover 1 on the top of the well seat 2, preventing damage to the top of the well seat 2, and further preventing the destruction of the well seat 2 from causing the manhole cover 1 to sink.

[0024] like Figures 1 to 4 As shown, a limiting hole 11 is symmetrically provided in the middle of the extrusion block 4 , and a limiting rod 12 is fixedly installed on the inner wall of the well seat 2 corresponding to the position of the limiting hole 11 , and the limiting rod 12 is slidably connected to the limiting hole 11 .

[0025] When the extrusion block 4 is extruding the well seat 2 , the movement of the extrusion block 4 is controlled by the limit rod 12 to ensure stable extrusion of the well seat 2 by the extrusion block 4 .

[0026] like Figures 1 to 4 As shown, the top of the well seat 2 is provided with a receiving hole 13 in a circular array with the central axis of the well seat 2 as the axis, the bottom end of the spring 5 is fixedly installed at the bottom of the receiving hole 13, and an extrusion rod 14 is fixedly installed at the bottom of the well cover 1 corresponding to the position of the receiving hole 13, the extrusion rod 14 is slidably connected to the receiving hole 13, and the top of the spring 5 is fixedly installed at the bottom of the extrusion rod 14.

[0027] When the manhole cover 1 is pressed down, the squeezing rod 14 at the bottom of the manhole cover 1 will slide inside the receiving hole 13, and the spring 5 will buffer the downward pressure of the manhole cover 1, further preventing the manhole cover 1 from squeezing the top of the well seat 2 and damaging it to cause the manhole cover 1 to sink. At the same time, the downward movement of the manhole cover 1 can be buffered to reduce the noise of the movement of the manhole cover 1.

[0028] like Figures 1 to 4 As shown, an anti-dropout rod 15 is fixedly installed at the inside of the mounting hole 3 corresponding to the top of the well seat 2 by fastening bolts, and a through hole 16 is opened at a position corresponding to the anti-dropout rod 15 on the well cover 1, and the anti-dropout rod 15 is slidably connected to the through hole 16.

[0029] When the manhole cover 1 rebounds due to the action of the spring 5 , the manhole cover 1 is restricted by the anti-falling rod 15 to prevent the manhole cover 1 from falling off the top of the manhole seat 2 .

[0030] like Figures 1 to 4 As shown, a rotating groove 17 is provided on the inner wall of the well seat 2 at a position corresponding to the bottom of the extrusion block 4, a rotating ring 18 is rotatably installed inside the rotating groove 17, and a triangular block 19 is fixedly installed in a ring array on the top of the rotating ring 18 with the central axis of the rotating ring 18 as the axis, and extrusion slopes 20 are provided on both sides of the extrusion block 4, and the extrusion slopes 20 and the triangular block 19 are extruded.

[0031] When removing the manhole cover 1, a stick is passed through the water inlet hole 6 to control the rotation of the swivel 18. The triangular block 19 on the swivel 18 will squeeze the extrusion slope 20 of the extrusion block 4, which will drive the extrusion block 4 to slide out of the limit rod 12, so that the manhole cover 1 can be lifted and removed.

[0032] like Figures 1 to 4 As shown, a protective cover 21 is fixedly installed at the bottom of the manhole cover 1 , and a water level monitor 7 is fixedly installed inside the protective cover 21 .

[0033] The water level monitor 7 can be protected by the protective cover 21 to prevent the water level monitor 7 from getting wet.

[0034] The utility model provides an anti-sinking manhole cover with real-time monitoring and early warning, and the specific working principle is as follows:

[0035] When the device is in use, when a car or other heavy weight presses down the manhole cover 1, the pressing down of the manhole cover 1 will drive the transmission rod 9 to move downward. Since the extrusion block 4 slides between the two limit rods 12, it will drive the extrusion block 4 to move between the two limit rods 12, and thus will also drive the transmission rod 9 to rotate. At this time, the four extrusion blocks 4 will squeeze the inner wall of the well seat 2, and transmit the downward pressure of the manhole cover 1 to the extrusion force of the extrusion blocks 4 on the well seat 2, thereby reducing the extrusion of the manhole cover 1 on the top of the well seat 2, preventing damage to the top of the well seat 2, and further preventing the well seat 2 from being damaged and causing the manhole cover 1 to sink;

[0036] When the manhole cover 1 is pressed down, the squeezing rod 14 at the bottom of the manhole cover 1 will slide inside the receiving hole 13, and the spring 5 will buffer the downward pressure of the manhole cover 1, further preventing the manhole cover 1 from squeezing the top of the well seat 2 and damaging it to cause the manhole cover 1 to sink. At the same time, the downward movement of the manhole cover 1 can be buffered to reduce the noise of the movement of the manhole cover 1.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
