Description

Fixed buoy

Technical Field

The utility model relates to a buoy especially relates to a fixed buoy.

Background

The buoy is a navigation mark floating on the water surface, and is marked through an anchor chain and an anchor fixed at the water bottom. Buoys are widely used and function to indicate range of the channel, indicate shoals or obstacles that compromise navigation safety. The buoys can be divided into sea buoys and inland river buoys according to the water areas in which the buoys are arranged. The basic shapes of the offshore buoy are tank shape, cone shape, column shape, rod shape, etc. The buoy is influenced by wind, wave and tide, so that the buoy body has a certain floating range and cannot be used as a mark for measuring the position of the ship.

As the technology is continuously improved, the buoy technology is mature, but the fixing method is extremely limited. If the slipknot type rod-shaped buoy is adopted, the position is accurate, the buoy can reset after being collided, but the flexibility of the slipknot device is limited to a certain extent, and the service cycle is limited. The existing deep sea buoy generally adopts an inverted S-shaped fixing method, the method effectively solves the problem of rope search when the plane rises and falls, but cannot solve the problem of buoy offset, and the buoy is easy to offset in actual use.

SUMMERY OF THE UTILITY MODEL

Utility model purpose: the utility model aims at providing a little, the fixed buoy that fixed strength is high of skew degree that receives external influence.

The technical scheme is as follows: the utility model discloses a fixed buoy, including first body, second body, first haulage rope, second haulage rope and heavy object.

The second floating body is arranged below the first floating body and connected with the first floating body through a first traction rope, and at least two second floating bodies are arranged.

The sinking and dropping object is arranged at the bottom of the water and is connected with the second floating body through a second traction rope.

The buoy is provided with a third traction rope connected with adjacent second floating bodies, and the number of the sinking objects is smaller than that of the second floating bodies.

When the number of the second floating bodies exceeds 4, the buoy is provided with third pull ropes which are connected with all the second floating bodies in pairs, and the number of the second pull ropes and the number of the sinking objects are smaller than that of the second floating bodies.

The second floating bodies are positioned at the same horizontal height.

The second float may be spherical.

The volume of the second floating body is determined according to the depth of the water body.

Has the advantages that: compared with the prior art, the utility model has the advantages of it is as follows showing: the utility model discloses a haulage rope is in the state of straightening all the time through the natural buoyancy of second body and the thing pulling force that sinks, has reduced the degree that the buoy takes place the skew, is applicable to the water of multiple topography and the degree of depth.

Fig. 1 is a schematic structural diagram of the present invention.

Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1, the fixed buoy of the present invention comprises a first floating body 1, a second floating body 2, a first pulling rope 3, a second pulling rope 4 and a sinking object 5.

The first floating body 1 floats on the water surface, a first traction rope 3 is connected below the first floating body 1, and the tail end of the first traction rope is connected with a second floating body 2. The first hauling ropes 3 are the same as the second floating bodies 2 in quantity, the adjacent first hauling ropes are in a certain angle, and the number of the second floating bodies is at least two. The second body 2 can be located at the same horizontal plane position, namely, the lengths and included angle degrees of the adjacent first hauling rope 3 and the second hauling rope 4 are the same, and the structure is suitable for the condition that the water bottom is gentle. All the second floating bodies can be positioned at different horizontal heights, and the device is suitable for the conditions that the bottom of the water body is uneven or has a slope and the like.

When the water depth is shallow (the water depth is less than 60m), the second floating body 2 is located within 10m below the water level. When the depth of the body of water is deep, the second floating body 2 is located within 50m below the water level.

A second traction rope 4 is connected below the second floating body 2, and the tail end of the second traction rope is provided with a sinking object 5 which sinks at the bottom of the water body. The number of the second traction ropes 4 and the sinker 5 is the same as that of the second floating body 2. The second hauling cable 4 is vertical to the bottom of the water body or forms a certain angle with the bottom of the water body.

In this embodiment, the buoyancy of the water body applied to the second floating body 2 is F1, the pulling force applied to the sinker 5 and the second hauling rope is denoted as F2, and F1 and F2 generate an outward resultant force of F3. The F3 on different second floats are respectively outward, so that the pull rope is in a stretched state at any time, and the buoy is prevented from deviating.

A third hauling rope can be arranged between the second floating bodies 2 and is connected with the adjacent second floating bodies. When the number of the second floating bodies exceeds 4, all the second floating bodies are connected in pairs to form a second floating body network, so that the positioning accuracy of the buoy is improved, and the offset of the buoy is reduced. With this structure, the number of the falling objects 5 can be smaller than the number of the second floating bodies, and the weight of the falling objects can be increased appropriately.
