2. The power drum type ice guiding rope has the characteristics of standardized production and reliable quality, adopts mature technology and is simple in structure and wide in application range. This lead ice cable structure is less to the influence of rivers, but the icicle along with the rivers motion will be at this drum-type effective change direction of motion under leading the ice cable effect, simultaneously because the electronic roll design of cylinder, can effectively avoid the icicle to take place to pile up before this leads the ice cable, can realize effectively reducing the defeated ice pressure in low reaches, reduces the low reaches and takes place the possibility of extreme ice damage such as ice plug, ice dam, effectively ensures the safety and stability of ice period water delivery.

Detailed Description

The present invention will be described in further detail with reference to the following drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

A dynamic drum-type ice guiding rope for a canal in a cold region is obliquely arranged on the downstream side of an ice discharge canal and forms a certain included angle with a main canal as shown in figure 1. As shown in fig. 2 and 3, the ice guiding rope is composed of a roller floating body 1, a roller main body 2, a roller weight 3, a roller rotating shaft 4, a steel wire rope 5, a motor 6, an upper anchoring pile 7, a fixing bayonet 8 and a lower anchoring pile 9. The roller floating body 1, the roller main body 2 and the roller ballast 3 form a roller structure, and the motor 6 is embedded in the roller main body 2. The drum structure can rotate around the drum shaft 4 under the action of the motor 6. To further reduce the friction when the drum structure is rotating, bearings may be added between the drum structure and the drum shaft 4. Two wire ropes 5 are respectively fixedly connected with the top and the bottom of the rotary shaft 4 of the roller, and a plurality of roller structures are connected in series in the mode. The number of the roller structures is determined by the required ice guide rope length and the canal slope coefficient. Two ends of the upper and lower steel wire ropes 5 are respectively and fixedly connected to the upper anchoring pile 7 and the lower anchoring pile 9 through fixing buckles 8.

The working principle of the dynamic drum type ice guiding rope for the canal in the cold region is as follows:

when the ice amount is small and severe ice conditions such as ice plugs and ice dams do not occur, the motor can not be started, and because the power roller type ice guiding rope structure forms an included angle with the water flow direction, the ice impact force and the continuous extrusion force are decomposed into a force (vertical force) vertical to the roller surface and a force (tangential force) tangential to the roller surface. The tangential force will make the roller roll, and the static friction acting force or sliding friction acting force between the ice and the roller will be converted into rolling friction acting force, thereby improving the ice guiding effect.

Great when the icicle volume, perhaps take place the icicle and pile up, block up the condition of crossing the water section, then can the starter motor, the motor drives the cylinder initiative rotation, utilizes the uneven surface of cylinder, and the direction effort of increase cylinder to the icicle makes the icicle to the predetermined direction motion, effectively avoids a large amount of accumulations of icicle.

Meanwhile, the roller is composed of a roller floating body with the density of the upper part smaller than that of water, a roller weight with the density of the lower part larger and a roller main body with the middle part having better anti-friction capability, so that the stability of the roller type ice guiding rope is better, and the self anti-torsion properties of the upper ice guiding rope and the lower ice guiding rope also increase the stability of the roller type ice guiding rope under the vertical force action. Therefore, the power drum type ice guiding structure is strong in self stability, good in ice guiding effect and wide in application range.

In the embodiment, the included angle between the ice guide rope and the main channel is 60 degrees, the diameter of the roller floating body 1 is 30cm, and the height of the roller floating body is 10 cm; the diameter of the roller body 2 is 30cm, and the height is 20 cm; the roller is pressed to weigh 3 cm, the diameter is 30cm, and the height is 10 cm; the length of each of the two steel wire ropes is 25m, and 2.5m of allowance is reserved at each of two ends of each steel wire rope so as to correspond to water level change; the roller spacing is 10cm, and the total number of roller structures is 50.

The present invention is not limited to the above-described embodiments. The above description of the embodiments is intended to describe and illustrate the technical solutions of the present invention, and the above embodiments are merely illustrative and not restrictive. Without departing from the spirit of the invention and the scope of the appended claims, the person skilled in the art can make many changes in form and detail within the teaching of the invention.
