Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of ice breaking device, concretely relates to an ice breaking device for flexible application to ice flood. BACKGROUND

[0002] Ice flood usually occurs in high latitude and high cold area. The rivers in the north can have ice flood in the river closing period of winter and the river opening period of spring. It can cause embankment to collapse, flood to spread, affect water power generation, navigation, water supply and the like, and bring threat to production and life. Therefore, it is necessary to break the ice surface of the river in the river closing period and the river opening period to prevent ice flood.

[0003] The Chinese application with publication number CN103485317A discloses a crank connecting rod impact type ice breaking device. In the device, the ice breaking device is installed on a tractor, the tractor moves on the ice surface, and the ice breaking device breaks ice at the back. The relative distance between the ice breaking device and the ice surface is always unchanged, so the ice breaking device can break ice.

[0004] However, the above ice breaking device cannot be installed on a truss for use. Because when the ice breaking device is installed on the truss, the height of the ice breaking device relative to the truss is unchanged, but the water surface changes every year due to the change of water level, that is, the height of the water surface relative to the truss is uncertain. This leads to the following consequences:

[0005] If the installation position of the ice breaking device is low, the hydraulic pick of the ice breaking device can be below the water surface, which can easily cause the hydraulic pick and the ice surface to freeze together after freezing, resulting in the ice breaking device being unable to break ice. Conversely, if the installation position of the ice breaking device is high, the ice surface is far away from the ice breaking device, and only the height of the ice breaking device itself cannot ensure that the ice breaking device can contact the ice surface.

[0006] Therefore, it is necessary to design an ice breaking device that can change the installation height, so that the ice breaking device can be installed on the truss and adapt to different heights of the ice surface in different years. CONTENT OF THE UTILITY MODEL

[0046] Scissor type connecting rod, belongs to prior art. Scissor type connecting rod comprises multiple high-low arranged cross assemblies, in the embodiment, the cross assemblies are two, recorded as cross assembly one and cross assembly two from top to bottom. The cross assembly comprises the same connecting rod A and connecting rod B, the connecting rod A and the connecting rod B are rotatably connected through a center shaft, the axis of the center shaft is along the Y direction, in the top view, the Y direction is perpendicular to the X direction.

[0047] ​The upper end of the connecting rod A of the cross assembly one is rotatably connected to the first fixed base 2 through shaft one 6, and the upper end of the connecting rod B of the cross assembly one is rotatably connected to the first sliding base 3 through shaft two 7; the upper end of the connecting rod A of the cross assembly two is rotatably connected to the lower end of the connecting rod B of the cross assembly one through shaft three 8, and the upper end of the connecting rod B of the cross assembly two is rotatably connected to the lower end of the connecting rod A of the cross assembly one through shaft four 9; the lower end of the connecting rod A of the cross assembly two is rotatably connected to the second sliding base 5 through shaft five 10, and the connecting rod B of the cross assembly two is rotatably connected to the second fixed base 4 through shaft six 11.

[0052] The eccentric shaft 15 is welded and fixed to the driving disc 14 at a position other than the center of the driving disc 14, and the axis of the eccentric shaft 15 is parallel to the rotating shaft axis of the motor 13.

[0053] The linkage plate 16 is sleeved on the eccentric shaft 15 and can rotate relative to the eccentric shaft 15 around the axis thereof. A vertical plane passing through the axis of the eccentric shaft 15 is plane P, and a plurality of planes P are provided with two groups of linkage assemblies, which include:

It is noted that the rotation shaft of the first connecting rod 17 is not connected to the driving disc 14 but only connected to the linkage plate 16, so that the linkage plate 16 can rotate around the axis of the eccentric shaft 15 during rotation of the driving disc 14.

[0055] The second connecting rod 18 is rotatably connected to the lower end of the first connecting rod 17 at the upper end thereof. The rotation shafts of the upper and lower ends of the first connecting rod 17 are both in the Y direction.

[0056] The ice breaking assembly further includes:

[0058] The spring 20 is fixed at both ends thereof to the two first connecting rods 17 by welding. The spring 20 is in a natural state.

[0059] The ice pick 21 is fixed to the lower surface of the cross rod 19 by welding, and the axis of the ice pick 21 is vertically arranged. The ice pick 21 is movably clamped on the truss 22 and can move vertically. The truss 22 is provided with a sleeve ring for sleeving the ice pick 21, and the ice pick 21 is movably clamped on the sleeve ring.

[0060] Use process of the ice breaking device

[0061] The second fixed base 4 and the second sliding base 5 of the device are connected to the truss in the above-mentioned connection manner. The number of the device on one truss is not one but several, and is arranged at intervals along the length of the truss. The truss is arranged on the mounting frame arranged at the ice flood occurrence position, and the number is not limited to one. One truss is arranged every 5-10 meters on the water surface where ice flood is prone to occur, and a plurality of trusses are arranged to cover the ice flood occurrence position as much as possible.

[0062] During the period when no ice flood occurs, a person will subjectively supply oil to the hydraulic cylinder to elongate, so that the lifting assembly is raised to the highest position, the other connecting rods are correspondingly moved, the hydraulic cylinder 12 finally drives the mounting plate 1 to be raised, and the ice breaking assembly on the mounting plate 1 is correspondingly raised, so that the lower end of the ice pick 21 can be separated from the water surface. During the cold period, the water surface begins to freeze, and because the ice pick 21 is separated from the water surface, the ice pick 21 will not be frozen together with the water surface.

[0063] Before the occurrence period of ice flood, generally when the upstream starts to melt, the ice surface at the position where the ice flood is prone to occur needs to be chipped. First, the lifting assembly needs to be lowered by a certain distance (manually control the hydraulic cylinder to return oil to shorten), to ensure that the ice chopper 21 reaches the distance that can hit the ice surface, and then the motor 13 is started, the motor 13 drives the eccentric shaft 15 and the driving disc 14 as a whole to rotate around the rotating shaft of the motor 13. In this process, the linkage plate 16 will deflect around the axis of the eccentric shaft 15, and at the same time, the linkage plate 16 will also produce vertical lifting movement. Then the linkage plate 16 constantly lifts and lowers the ice chopper 21 through the linkage assembly to chip the ice surface. After the ice choppers on the trusses work simultaneously, most of the ice surface in the area where the ice flood is prone to occur can be chipped, and during the occurrence of the ice flood, there are no large ice blocks to hinder the flow of the water body from the upstream melting, so the ice flood cannot naturally cause harm.

[0064] Based on the above ideal embodiments of the present application, through the above description, relevant personnel can make various changes and modifications without deviating from the technical idea of the present application. The technical scope of the present application is not limited to the content in the specification, and must be determined according to the scope of the claims.
