Abstract

The utility model discloses a combined device for preventing weeds from being wound on a cable, which is characterized by comprising at least two turning floats which are connected. Each turning float comprise an inner tube and an outer tube, the inner tube are sleeved in the outer tube, the outer tube is internally provided with a buoyancy cavity, the outer tube and the inner tube are connected through a bearing, and the inner tube is sleeved on a fixing cable of a ship; the upper end and the lower end of the inner tube extend out of the outer tube, and the diameter of the upper end of the inner tube is larger than the diameter of the lower end of the inner tube; and the inner wall of the upper end of the inner tube is provided with a annular slot for a clamping ring, and the outer wall of the lower ends of the inner tube are respectively provided with the clamping ring. By adopting the device, floating debris and weeds can be prevented from being wound on the fixing cable of the ship, and the floating debris and weeds is needed to be mutually cleaned. By adopting the multi-section combined structure, the mold opening cost in manufacturing can be reduced, and adaptive layout can be achieved easily according to characteristics of different waters.

Description

The compound type hawser is prevented careless wrapping head

Technical field

The utility model relates to the anti-careless wrapping head of a kind of compound type hawser.

Background technology

During the fixedly hawser of river crafts such as beacon vessel is everlasting and is risen by windings such as upstream floating debris, weeds, after hawser is wound, need clear up, in order to avoid pull ship after twining more and more, cause the inclination of ship, shipwreck also might take place in the beacon vessel that weight is lighter, influences the normal use of beacon vessel.At present, relevant departments can only send someone to go by ship with a chainsaw or manpower is cleared up one by one, not only waste of manpower, material resources, but also bring life danger might for the cleaning personnel.

The defective of prior art is: river crafts such as the beacon vessel fixedly floating debris on the hawser can only cause the waste of human and material resources by manually clearing up, and the personal safety of clearing up personnel simultaneously also can not get ensureing fully.

The utility model content

The purpose of this utility model is to provide a kind of compound type hawser to prevent careless wrapping head, can clear up floating debris voluntarily, prevent ship fixedly hawser twined by upstream floating debris, weeds.

The technical solution of the utility model is as follows: a kind of compound type hawser is prevented careless wrapping head, its key is: connected to form by at least two upset floating drums, described upset floating drum is made up of the inner core and the urceolus that are sleeved on together, have buoyancy cavity in the described urceolus, be connected by bearing between this urceolus and the inner core, described inner core is sleeved on the fixedly hawser of ship;

Anti-careless wrapping head can slide up and down or rotate along hawser, and its position on hawser is by buoyancy adjustment, can adapt to the fluctuation of water level automatically and remains on the water surface.Upstream floating debris, weeds etc. can only be attached on the anti-careless wrapping heads, and do not contact with fixing hawser.When point in the horizontal surfaces at river such as floating debris, weeds lower reaches of river make a concerted effort with ship to be offset about fixedly the hawser center has slightly the time, the balance of preventing careless wrapping head is broken and is rotated, and floating debris, weeds etc. is drained.

Described urceolus is all stretched out in the top and bottom of described inner core, and the diameter of the upper end of inner core is greater than the diameter of inner core lower end;

And the upper end inwall of inner core has the collar annular groove, and the lower end outer wall of inner core is provided with collar.

Described bearing is positioned at the two ends of described urceolus.

Connection bearing between inner core and the urceolus can improve the rotate effect of preventing careless wrapping head, foreign material occur between inner core and hawser, when resistance relates to the inner core rotation, can also rotate relatively between inner core and the urceolus, has guaranteed the work effect of anti-careless wrapping head.

Remarkable result of the present utility model is: the fixedly hawser that can prevent ship is twined by upstream floating debris, weeds, and does not need labor cleaning's floating debris, weeds.The multistage unitized construction can reduce the die sinking cost of manufacturing, is easy to carry out comformability according to the characteristic in different waters and arranges.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the scheme of installation of bearing;

Fig. 3 is running condition figure of the present utility model.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples:

Shown in Fig. 1,3, a kind of compound type hawser is prevented careless wrapping head, connect to form by at least two upset floating drums, described upset floating drum is made up of the inner core 1 and the urceolus 2 that are sleeved on together, have buoyancy cavity 3 in the described urceolus 2, be connected by bearing 6 between this urceolus 2 and the inner core 1, described inner core 1 is sleeved on the fixedly hawser 4 of ship 5;

Described urceolus 2 is all stretched out in the top and bottom of described inner core 1, and the diameter of the upper end of inner core 1 is greater than the diameter of inner core 1 lower end;

And the upper end inwall of inner core 1 has collar annular groove a, and the lower end outer wall of inner core 1 is provided with collar b.

The design of collar annular groove a and collar b has realized that multistage upset floating drum bonded assembly connects successively.In the more waters of weeds, can adopt the combination of multi-segment structure, in the less waters of weeds, can be only with one section upset floating drum.

As shown in Figure 2, described bearing 6 is positioned at the two ends of described urceolus 2.

Bearing 6 is the corrosion-resistant steel water-sealed bearing, can waterproof grommet 8 be installed in the both sides of bearing 6, and waterproof grommet 8 is embedded between urceolus 2 and the inner core 1, and assurance bearing 6 can not be intake and impurity.

Its service condition is as follows:

As shown in Figure 2, anti-careless wrapping head can slide up and down or rotate along hawser, and its position on hawser 4 is by buoyancy adjustment, can adapt to the fluctuation of water level automatically and remains on the water surface 6.Prevent the part of careless wrapping head this moment in water, a part is on the water surface 6.Upstream floating debris, weeds etc. can only be attached on the anti-careless wrapping heads, and do not contact with fixing hawser.When point in the horizontal surfaces at river such as floating debris, weeds lower reaches of river make a concerted effort with ship to be offset about fixedly the hawser center of gravity has slightly the time, the balance of preventing careless wrapping head is broken and is rotated, and floating debris, weeds etc. is drained.

Although above structure is described preferred embodiment of the present utility model in conjunction with the accompanying drawings; but the utility model is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment only is schematic rather than determinate; those of ordinary skill in the art is under enlightenment of the present utility model; under the prerequisite of the utility model aim and claim; can make multiple similar expression; as change the material of anti-careless wrapping head; the quantity of change upset floating drum; if material is lighter than water; can consider to reduce buoyancy cavity 3, even not want modes such as buoyancy cavity 3, as timber; light plastic; the length of preventing careless wrapping head can also be strengthened, overstriking, such conversion all falls within the protection domain of the present utility model.
