Embodiment 1

[0036] see Figure 1-5 , a magnetic levitation buffer shock-absorbing manhole cover based on the cooperative energy dissipation of elastic force and electromagnetic repulsion, characterized in that it includes a U-shaped manhole cover 1, a support plate 17 is fixed at the bottom end of the U-shaped manhole cover 1, and the support plate 17 and The installation groove 18 that is arranged on the inside of the installation foundation matches and enables it to be raised and lowered inside the installation groove 18; An electromagnetic buffer and shock absorbing mechanism and a spring buffer and shock absorbing mechanism are arranged at intervals. By adopting the shock-absorbing manhole cover of the present invention, it uses the principle of magnetic levitation combined with spring shock absorption and energy dissipation to solve the problems of untimely drainage of common manhole covers, poor seismic performance, easy settlement and shear damage of pavement concrete around the ma...

Embodiment 2

[0047] How to use the magnetic levitation cushioning and shock absorbing manhole cover:

[0048] When the load of a small vehicle is applied on the inverted U-shaped well cover 1, the conductive pulley 7 is located in the non-conductive area 16-1, the electromagnet 2 is in a power-off state, and only the first spring 4 of the spring buffer shock absorbing mechanism is stressed;

[0049] When a large vehicle load is applied to the well cover, the elastic force of the spring within the length of the non-conductive area 16-1 is not enough to resist the external impact load, the conductive pulley 7 slides into the area of ​​the effective adjustment area 16-2, and the electromagnet 2 generates a magnetic force, When the load continues to increase, the pulley slides downward, and the magnetic force of the electromagnet increases to resist the external impact load. At the same time, the external load is dynamically converted into magnetic field energy, reducing the force of the extern...

Abstract

The invention provides a magnetic suspension buffering and damping well lid based on cooperative energy dissipation of elastic force and electromagnetic repulsive force and a using method. The magnetic suspension buffering and damping well lid comprises a U-shaped well lid, a supporting plate is fixed to the bottom end of the U-shaped well lid, and the supporting plate is matched with a mounting groove formed in a mounting foundation and can ascend and descend in the mounting groove; a bottom cushion plate is arranged at the bottom end of the mounting groove, and an electromagnetic buffering and damping mechanism and a spring buffering and damping mechanism are arranged between the supporting plate and the bottom cushion plate at intervals. According to the magnetic suspension buffering and damping well lid based on cooperative energy dissipation of the elastic force and the electromagnetic repulsive force and the using method, a magnetic suspension principle is combined with spring damping and energy dissipation, and the problems that a common well lid is not timely in drainage and poor in anti-seismic performance, and concrete on the periphery of the well lid is prone to sedimentation shear damage are solved. The magnitude of electromagnetic force can be adjusted according to received pressure.

Description

technical field [0001] The invention relates to the technical field of municipal manhole covers, in particular to a magnetic suspension cushioning shock absorbing manhole cover based on elastic force and electromagnetic repulsion for energy dissipation and a method for using it. Background technique [0002] Existing sewer manhole covers are mostly round or square, and the material is mostly cast iron or cement. The manhole cover is exposed on the ground and is located in the pavement structure layer. Under the action of impact loads such as human disturbance and vehicle rolling, it is prone to problems such as damage, collapse, and rollover. If the manhole cover disease cannot be detected and dealt with in time, it will not only bring inconvenience to underground pipeline management, public life and traffic travel, but may also endanger the safety of people's lives and properties. In addition, the noise caused by cars rolling over them can cause the car to vibrate and dama...
