Waterproof and fireproof inspection well
The invention relates to a waterproof and fireproof inspection well and belongs to the technical field of electric power wells. The waterproof and fireproof inspection well comprises a well seat, a shaft, an inlet pipe and an outlet pipe. The shaft, the inlet pipe and the outlet pipe are joined at the well seat, the shaft is vertically arranged, and the inlet pipe and the outlet pipe are coaxially arranged. The shaft comprises a first cylinder shaft body, a first circular truncated cone shaft body and a second cylindrical shaft body, a concave clamping ring is arranged at the bottom end of the inner wall of the first cylindrical shaft body, a gas appliance is embedded at the clamping ring, the first circular truncated cone shaft body is in an inverted circular truncated cone shape, the first cylindrical shaft body is connected with the upper end of the first circular truncated cone shaft body, and the second cylindrical shaft body is connected with the lower end of the first circular truncated cone shaft body. An upper protection tool is clamped to the inner wall of the first circular truncated cone shaft body in a contact mode, and a middle pipe is erected between the inlet pipe and the outlet pipe. When a fire disaster occurs, the internal space is sealed by the inspection well, so that the inspection well and the peripheral space are effectively isolated, and thus spreading of the fire behaviors and the diffusion of smog are prevented.
