Abstract
The utility model discloses a protective device for preventing a water pipe from being cracked by frosting, and relates to a frost-heave preventing device for a water conservancy project. The frost-heave preventing device comprises a heat preservation pipe sleeve with a notch. A heating wire is arranged on the inner wall of the heat preservation pipe sleeve. A connecting pipe is arranged at the upper end of the heat preservation pipe sleeve. A temperature sensor is arranged on the connecting pipe. A heating device communicated with the connecting pipe is fixedly connected to the top end of the connecting pipe. A circuit controller and a power source are arranged inside the heating device. A solar cell for charging the power source is arranged at the top end of the heating device. The heating wire is controlled by the heating device. An asbestos heat preservation layer is arranged on the inner wall of the heat preservation pipe sleeve. The temperature sensor is installed in the frost-heave preventing device for the water conservancy project, the heating wire can be powered on to emit heat, the temperature inside the pipe rises to prevent frosting in advance, convenience is brought to dredging through electric current heating even though the pipe is frosted, and meanwhile the frosted pipe can be prevented from being cracked by heaving of ice through the placement of the frost-heave preventing device.
Description
Technical field
The utility model relates to hydraulic engineering technical field, and especially a kind of anti-antipriming pipe freezes and causes the protective device being split up.
Background technology
In winter, the aqueduct in the north meets with and easily freezes when strange cold and make water pipe freeze the serious frost crack pipe that even can make, and relevant device was lost efficacy, and causes damage and bothers.Because pipeline is generally all arranged on undergroundly, investigation difficulty is not said, repairs also quite effort, whenever northern cold current one is to seeing that service worker excavates ground and toasts the pipeline being frozen in or change by the pipe of bursting by freezing in the world of ice and snow, very difficult.
Summary of the invention
The technical problems to be solved in the utility model is: for the problem that the prior art solving in above-mentioned background technology exists, provide a kind of improved anti-antipriming pipe to freeze and cause the protective device being split up.
The utility model solves the technical scheme that its technical problem adopts: a kind of for the anti-icing expansion device of hydraulic engineering, comprise the heat-insulating cover with gap, described heat-insulating cover inwall is provided with heater strip, described heater strip is shape of threads and is fixed on heat-insulating cover inwall, described heat-insulating cover upper end is provided with tube connector, on described tube connector, be provided with temperature pick up, tube connector top is fixedly connected with the heating apparatus being connected with tube connector, described heating apparatus inside is provided with circuit controller and power supply, the signal output part of described temperature pick up and the electrical connection of the signal input part of circuit controller, the signal output part of described circuit controller and heater strip electrical connection, described heating apparatus top is provided with for the solar cell to power supply charging, described heater strip and circuit controller are powered by power supply, described heater strip is by heating apparatus control, described temperature pick up is connected with circuit controller by power lead, described power supply is connected with circuit controller by power lead, described heat-insulating cover inwall is provided with asbestos insulation layer, make heat-insulating cover in the effect that finishes also can play after power supply insulation, energy conservation.
Further, described heat-insulating cover adopts polyurethane thermal pipe.
Further, described heat-insulating cover outer wall is provided with polyvinyl chloride anticorrosive coat, can play effective anticorrosion ability, strengthens application life.
Further, described heating wire adopts insulated heating wire, plays effective insulation effect, has promoted safe class.
The beneficial effects of the utility model are, of the present utility model for mounting temperature sensor in the anti-icing expansion device of hydraulic engineering, not only can switch on and make electrothermal wire heating, make temperature in pipeline raise antifreeze in advance, even if freeze and be also convenient to dredging by current flow heats afterwards, risen brokenly by ice because inserting of this device can prevent the pipeline freezing simultaneously.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
