Description

An automatic electric heating bridge drainage pipe device suitable for severe cold areas

technical field

The utility model relates to the technical field of anti-icing of bridge drainage pipes, which is an automatic electric ice melting device for bridge drainage pipes based on severe cold regions.

Background technique

The average temperature of the coldest month in severe cold areas in my country is ≤-10℃. According to the survey, the bridge drainage pipes in severe cold areas are generally made of PVC material or cast iron material. Due to improper construction and quality defects, the drainage pipes used in the early days will have various disease problems. Even if they are replaced, it is difficult to avoid problems from the root cause. The icing of bridge drainage pipes in severe cold areas mostly occurs in: the nozzles of the drainage pipes, the connection parts of pipe joints and the water outlet of the drainage pipes. It is easy to freeze in the drain pipe in winter in severe cold regions. Once there is the phenomenon of freezing and blocking the pipeline, relevant units need to deal with it in time.

At present, the deicing methods of bridges in severe cold areas are mostly the use of snow melting agents, manual cooperation tools or machinery. This deicing method has problems such as low deicing efficiency, loud deicing noise, incomplete deicing, and certain risks in deicing operations.

SUMMARY OF THE INVENTION

The purpose of the utility model is to provide an anti-icing device suitable for automatic electric heating of drainage pipes in severe cold areas. The device has low energy consumption, simple structure, low cost, convenient operation and strong practicability. The materials used have the characteristics of low price, high efficiency and long life. The whole device is easy to manufacture and install, does not consume too much manpower, material resources and financial resources, and can save corresponding labor, and can avoid problems such as freezing in the pipe and blocking the drain pipe. The maintenance efficiency is improved to a certain extent, the deficiencies of the prior art are overcome, and the purpose is to effectively solve the problem of pipe blockage caused by the freezing of the bridge drainage pipe.

The technical scheme of the utility model is realized by the following measures: an automatic electric heating bridge drainage pipe device suitable for severe cold areas, including an outer pipe, a temperature controller, an inner lining pipe, a wire, a thermal insulation material, a wire clip, a carbon fiber Heating wire, temperature probe, grid cover, water inlet.

The cross section of the inner lining pipe of the drain pipe is a semi-cylindrical hollow aluminum alloy structure. It has certain strength, stiffness and thermal insulation performance, and the inner wall is smooth, sensitive to temperature changes, small resistance to fluid, not easy to corrode, and can meet the requirements of later service life.

The cross section of the outer pipe of the drain pipe is a semi-cylindrical hollow polyvinyl chloride structure. It has the advantages of odorless, anti-corrosion, anti-aging, good weather resistance, high impact strength, high mechanical properties, good toughness, strong bending resistance and wear resistance.

The temperature controller is arranged on both sides of the inner lining pipe and is connected with the conducting wire and the carbon fiber heating wire. It is used to receive the temperature signal of the temperature sensor to control the carbon fiber heating wire. The temperature sensing probe adopts a magnetic suction head, which is connected with the thermostat and is adsorbed on the lining pipe. It is necessary to sense whether the temperature inside the drain pipe is lower than the starting temperature set by the thermostat. Start the carbon fiber heating wire immediately to keep the temperature in the drain pipe within the set temperature. When the temperature in the pipe reaches the set stop temperature, the thermostat will control the carbon fiber heating wire to stop working. The set start temperature of the thermostat is Zero degrees Celsius, set the stop temperature to five degrees Celsius.

The carbon fiber heating wire is a new type of heating material, which is connected with the thermostat through wires. The wire clip is used to fix the ring on the inner lining tube, and the longitudinal carbon fiber heating wire is symmetrically arranged near the inner lining tube on both sides, and the wire clip is used to fix the work horizontally. Compared with ordinary heating cables, carbon fiber heating wires have the advantages of low price, rapid heating and high conversion rate. The carbon fiber heating wire converts electrical energy into heat energy, and transfers the heat to the lining tube to maintain the temperature through heat exchange.

The grid cover is made of organic material, and water inlet holes are symmetrically arranged on the grid cover.

The wire clip is a semi-cylindrical metal structure with circuit holes, welded on the inner lining tube, and used to fix the carbon fiber heating wire and the wire.

The insulation material adopts cotton and linen fabric, which is filled between the carbon fiber heating wire and the outer tube.

The beneficial effects of the utility model are as follows: by installing an electric heating automatic anti-icing device on the water discharge pipe of the bridge, and using a heating system composed of a temperature controller, a wire and a carbon fiber heating wire, on the one hand, the blockage of the water discharge pipe caused by the freezing in the pipe is solved. On the other hand, it solves the problem of damage to the drain pipe due to freezing in the pipe. The electric energy of the device is provided by the lighting system in the auxiliary facilities of the bridge, which can ensure the normal operation of the whole system. The utility model has reasonable structure and high utilization rate.
