摘要： The present invention relates to a system for thawing frozen pipes utilizing electricity. Specifically, the present invention relates to electrically charging a section of frozen pipe such that heat is generated and causes the ice therein to thaw. Even more specifically, the present invention relates to one or more ports disposed above specific portions of pipe that extend upwards towards a surface thereabove and provide electrical access to the specific portions of pipe from the surface.

摘要： According to an example, a system for managing a fluid condition in a pipe includes a controller to receive temperatures of the pipe detected by the temperature sensor over a period of time. The controller may determine, based upon the temperatures of the pipe over the period of time, a temperature profile of the pipe and may determine that the temperature profile of the pipe indicates that a freezing onset event has occurred. The freezing onset event may include a transition from a drop in temperature to an increase in temperature, in which the temperature during the transition is below a freezing point temperature of a fluid contained in the pipe. The controller may further trigger at least one of an alarm and an activation of a first freezing prevention device in response to the determination that the freezing onset event has occurred.

摘要： A system for providing access to a fire hydrant. The system includes an actuator extension having a first end and a second end spaced from the first end. The first end is configured to be mounted on an exterior location on the fire hydrant, so that the first end is operatively engaged with a valve actuator of the fire hydrant, the valve actuator being selectively rotatable to cause a valve of the fire hydrant to open and close. The second end is spaced from the first end and is configured to facilitate application of an externally-applied force and transmission of such force to the first end of the actuator extension.

摘要： An apparatus for heating liquid in a pipe to prevent freezing of the liquid and for de-icing of frozen pipes includes an elongated housing constructed of plastic material and having a central bore and fittings for detachably coupling each end of the housing to the open end of a liquid pipe so that the central bore connects a first liquid pipe to a second liquid pipe. The fittings each comprise a sleeve attachable to the pipe end, a sealing gasket between the end of the housing and an annular flange on the sleeve, and a threaded coupling nut cooperating with external threads on the housing and having a flange engaging the sleeve flange. The housing includes a lateral passageway intermediate its end communicating with the central bore and closed by a sealer valve having an opening with a normally closed penetrable seal of elastomeric material. An elongated electric resistance heating cable, including a probe containing an electric heating core at the free end thereof, is slidably insertable through the penetrable seal into the housing bore and then into one of the pipes through the open end thereof. An electric control means including a switch and rheostat is mounted on the housing and connected to the heating cable for controlling the operation and temperature of the heating cable. The cable is sufficiently rigid to allow the cable to be pushed through the sealer valve into the bore and flexible enough to follow the contour of the pipe bends as the cable is pushed into the pipe.

摘要： An apparatus and method for thawing frozen lines. Water is heated and supplied under pressure to the inside of a frozen line such as a frozen plastic or metal pipe. In one non-limiting embodiment the invention comprises an air compressor, a plurality of tanks, a water heater element located in one tank, and a reel of flexible tubing. In a preferred embodiment the complete kit is mounted on a carrying device, which can be maneuvered manually through standard size doorways. In one embodiment a water delivery nozzle made of heat conducting metal is fitted to one end of the tubing. The compressor can be an electrically powered air compressor thus allowing the invention to be used inside buildings. In another embodiment deicing agent is directed into a frozen pipe in controlled pulses to further aid thawing of frozen lines.
