Description

An automatic electric melting ice pick device for urban viaducts suitable for severe cold areas

technical field

The utility model relates to the technical field of ice pick treatment for urban viaducts, which is an automatic electric melting ice pick device for the seepage of urban viaducts based on severe cold regions.

Background technique

According to the survey, the span structures of urban viaducts in severe cold areas in my country are mostly simply supported beams or continuous beams, and the average temperature of the coldest month in severe cold areas is ≤-10℃. Due to improper construction and management, urban viaducts built in the early days will have various disease problems. Even if they are maintained and treated, it is difficult to avoid problems from the root cause. The formation of dripping ice cones of viaducts in severe cold areas mostly occurs in the wet joints of fabricated slab girder with inferior concrete seepage, and the cracks under the bridge span structure. In view of the poor quality and construction quality of the expansion joints, the poor working environment, the frequent jamming of falling debris, and the untimely cleaning, etc., the leakage of bridge expansion joints is a common phenomenon, and it is hopeless to overcome in a short time. Easy to form ice cones. Once ice picks exist, relevant departments need to remove them in time.

At present, there are many ways to deal with ice picks for urban viaducts in severe cold areas, which are to use manual cooperating tools or mechanical deicing. This de-icing method has problems such as temporary occupation of roads, clearing and falling of broken ice, low de-icing efficiency, loud de-icing noise, incomplete de-icing, and certain risks in de-icing operations.

SUMMARY OF THE INVENTION

The purpose of the utility model is to provide an automatic electric melting ice pick device suitable for urban viaducts in severe cold areas.

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 mechanical costs, and can avoid problems such as noise and temporary occupation of roads when handling ice picks. The maintenance efficiency is improved, the deficiencies of the prior art are overcome, and the purpose is to effectively solve the problems of smashing and injuring passing vehicles or pedestrians due to the falling of the ice cone at the water seepage place of the urban viaduct.

The technical scheme of the utility model is realized by the following measures: an automatic ice pick prevention device for an urban viaduct, comprising a water collecting tank, a temperature controller, a wire, an upper line hole, a lower line hole, a connecting pipe, a wing plate, and a carbon fiber heating wire .

The outer shape of the water collecting tank is a hollow aluminum alloy structure with an open top and a semi-cylindrical cross section. It has certain strength, stiffness and thermal insulation properties, and the inner wall is smooth, sensitive to temperature changes, and has little resistance to fluids. The upper and lower line holes for burying the thermostat, carbon fiber heating wires and wires are reserved at the bottom of the sump. A reasonable one-way gradient of 1%-2% is set at the bottom of the water collection tank, which is conducive to draining the water to the bridge discharge pipe. Considering the purpose of the whole device, the water collecting tank is mainly installed at the water seepage point of the viaduct under the vertical and horizontal bridges and pedestrians crossing the street, so as to avoid accidents caused by falling ice picks. The device can be designed with corresponding dimensions on the basis of the existing model according to the water flow size, flow rate and flow rate at the seepage place.

The temperature controller is embedded in the lower line hole at the bottom of the water collecting tank, and is connected with the 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 inner wall of the sump through the connecting pipe. It is necessary to sense whether the temperature inside the sump is lower than the starting temperature set by the thermostat. The thermostat will immediately start the carbon fiber heating wire to work to keep the temperature of the inner wall of the sump within the set temperature. When the temperature reaches the set stop temperature, the thermostat will control the carbon fiber heating wire to stop working. The start temperature is zero degrees Celsius, and the set stop temperature is five degrees Celsius.

The carbon fiber heating wire is a new type of heating material, which is arranged in the lower circuit hole at the bottom of the water collecting tank, and is connected with the thermostat through a wire. Compared with ordinary heating cables, it has 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 inner wall of the sump to maintain the temperature through heat exchange.

The upper line hole is arranged at the bottom of the water collecting tank, and the carbon fiber heating line and the temperature sensing probe are embedded in the inside thereof.

The lower line hole is arranged below the upper line hole at the bottom of the water collecting tank, and the inner diameter is larger than that of the upper line hole, and the temperature controller, the wire and the temperature sensing probe are embedded in the inside thereof.

The connecting pipe is arranged between the upper and lower circuit holes, and a wire and a temperature-sensing probe are embedded in the connecting pipe, which is used to connect the temperature controller and the carbon fiber heating wire.

The wing plates are rectangular aluminum alloy sheets, welded on both sides of the top of the water collecting tank, and provided with holes. Use the fixing device expansion bolts to pass through the holes of the wing plate to fix it at the seepage point under the bridge span structure of the viaduct.

The beneficial effects of the utility model are as follows: on the one hand, the problem of slippery road under the bridge caused by the water seepage of the viaduct is solved by installing an automatic ice pick prevention device at the water seepage place of the viaduct and using a heating system composed of a thermostat, a wire and a carbon fiber heating wire. On the other hand, the continuous expansion of the ice-covered volume at the seepage of the viaduct has solved the problem of its falling. The electrical 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 device. The utility model has reasonable structure and high utilization rate, and greatly reduces the risk factor of the ice pick falling. In severe winter areas, it can ensure the safety of pedestrians and passing vehicles under the urban viaduct to a certain extent.
