Water and fire prevention communication inspection well
The invention discloses a water and fire prevention communication inspection well and belongs to the technical field of electric power wells. The water and fire prevention communication 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 converged to the well seat. The well seat is vertically arranged. The inlet pipe and the outlet pipe are coaxially arranged. The shaft comprises a first cylinder, a first circular truncated cone drum and a second cylinder. A concave clamping ring is arranged at the bottom end of the inner wall of the first cylinder. A gas appliance is embedded in the clamping ring. The first circular truncated cone drum is in an inverted circular truncated cone shape, the upper end of the first circular truncated cone drum is connected with the first cylinder, and the lower end of the first circular truncated cone drum is connected with the second cylinder. An upper protection tool is in contact with the inner wall of the first circular truncated cone drum in a clamping mode. A right protection tool is embedded in an inlet of the inlet pipe. A left protection tool is embedded in an inlet of the outlet pipe. When a fire happens, the internal space of the inspection well is sealed, and therefore the inspection well is effectively isolated from the peripheral space, and spreading of the fire behavior and smoke is prevented.
