| Zusammenfassung: | The utility model relates to a technology for protecting a dam observation pillar, in particular to a protection device for the dam observation pillar, which comprises a shell, a shielding device and a connecting device, the protection device is fixed to the dam observation pillar through the shell, and the shielding device and the connecting device are arranged on the shell. The shielding device can be unfolded or stacked on the surface of the connecting device; the connecting device is used for sleeving the observation pillar. The protection device is arranged on the observation pillar in a sleeving mode through the connecting device, the shielding device can be unfolded or stacked on the surface of the connecting device, and when the shielding device is unfolded, the shielding device covers the surface of the connecting device, so that a forced centering hole of the dam observation pillar is shielded, and the situation that the forced centering hole is blocked by impurities such as leaves is prevented; whe |
