the utility model provides a ward off glass manhole, includes the manhole body, install the protective sheath in the manhole body, the protective sheath includes fixed connection's the upper cover and the cover body, the upper cover sets up in manhole body upper end, the cover body sets up inside the manhole body and extends to manhole body lower extreme.

As a further technical solution of the present invention: the cover cap and the cover body are integrally formed, and the outer diameter of the cover body is larger than the inner diameter of the manhole body.

As a further technical solution of the present invention: a through hole is formed in the protective sleeve.

As the utility model discloses a further technical scheme again: the protective sleeve is made of polytetrafluoroethylene.

As the utility model discloses a further technical scheme again: the outer surface of the sleeve body is provided with threads.

As the utility model discloses a further technical scheme again: the manhole body upper end is fixed with the flange still, the flange sets up between manhole body and protective sheath.

As the utility model discloses a further technical scheme again: and a glass lining layer is fixedly arranged on the surface of the flange.

Compared with the prior art, the beneficial effects of the utility model are that: 1. the reliability is obviously improved, and the damaged part is protected doubly; 2. the cost is low when the device is used for repairing the device, and the device is only one tenth of the whole compound enamel; 3. the device is particularly suitable for large-scale equipment, and when the equipment is installed at a position which is not easy to dismantle, the equipment can be repaired on site.
