Problems solved by technology

In the actual application process of this kind of system, there are many complex problems
First of all, in order to ensure that the positioning system has a certain impact resistance, heavy metal anchor chains are mostly used for ropes, and the length is greater than the water depth, which is prone to the phenomenon of anchor chain dragging the ground, resulting in wear and tear of the anchor chain. The longer the time, the greater the wear rate. Or the metal anchor chain is easy to rust and break
Secondly, due to the movement of sea waves, the floating body is in a state of motion, moving around the bottom anchor point, the longer the rope, the larger the range of motion, the positioning is not accurate enough, and the accuracy is low

Embodiment 1

[0021] like figure 1 As shown, it is a traditional floating body, the water depth is 15m, the positioning rope is a metal anchor chain, the length needs to be 45m, and the maximum displacement diameter of the floating body is 85m. like figure 2 As shown, the application of a floating body positioning system of the present invention on a floating body includes a floating body 1, a positioning rope 2 and an anchor point 3. One end of the floating body 1 is connected to the positioning rope 2, and the other end of the positioning rope 2 is fixed on the anchor point. On point 3, the positioning rope 2 is a fiber cable, which is strong and durable, and is resistant to corrosion by seawater. The positioning rope 2 includes a suspension rope 21 and a traction rope 22. One end of the suspension rope 21 is connected to the floating body 1, and the other end of the suspension rope 21 is connected to the traction rope 22. At the same time, the connection between the suspension rope 21 ...

Embodiment 2

[0025] like Figure 4 As shown, it is another embodiment of the present invention. The difference from Embodiment 1 is that this embodiment adopts two anchor points 3 and two traction ropes 22. The traction ropes 22 are respectively connected to the anchor points 3, and the suspension ropes One end is connected to the floating body 1, the other end is connected to two traction ropes 22, a counterweight system 23 is provided at the connection, a floating ball 24 is provided at the lower end of the two traction ropes 22, and the distance between the two anchor points 3 is E, The water depth P, L is the length of the traction rope 22, wherein, L is equal to 1 times the parameter E, E=P, P is 20m, and the length of the suspension rope is 1 / 2P=10m. Figure 5 The movement range of the floating body 1 is shown in Fig. 1. The movement range of the floating body is in a fusiform shape, and the movement diameter is 25m.

Embodiment 3

[0027] like Image 6 As shown, it is another embodiment of the present invention. The difference from Embodiment 2 is that this embodiment adopts three anchor points 3 and three traction ropes 22. The traction ropes 22 are respectively connected to the anchor points 3, and the suspension ropes One end is connected to the floating body 1, the other end is connected to three traction ropes 22, a counterweight system 23 is provided at the connection, and a floating ball 24 is provided at the lower end of the three traction ropes 22, wherein the distance between the two anchor points 3 is ΦD , the water depth P, L is the length of the traction rope 22, where L is equal to 0.8 times the parameter ΦD, ΦD=P, P is 20m, the length of the suspension rope is 1 / 2P=10m, and the length of the traction rope 22 L is 16m. Figure 7 The moving range of the floating body 1 is shown in Fig. 1. The moving range of the floating body is smaller than that in Example 2. The rotation radius of the floa...

Abstract

The invention relates to a positioning system and in particular relates to a floating body positioning system. The floating body positioning system comprises a floating body, a positioning rope and an anchor point, wherein one end of the floating body is connected with the positioning rope; the other end of the positioning rope is fixedly arranged on the anchor point; the positioning rope comprises a suspension rope and a traction rope; a counterweight system is arranged at the joint of the suspension rope and the traction rope; a floating ball is arranged on the traction rope; the length of the traction rope from the floating ball to the anchor point is smaller than the length of the traction rope from the counterweight system to the anchor point; at least one anchor point is formed; and at least one traction rope is arranged. According to the floating ball and the counterweight system, the motion range of the floating body is narrowed and the accuracy is improved; with increase of the number of the anchor points, the motion range of the floating body is gradually narrowed and the positioning accuracy is greatly improved; and moreover, according to the floating body, the problem that the traction rope falls on the ground is solved. According to the system disclosed by the invention, fiber cables serve as the traction ropes and the suspension ropes, and the system is solid, durable, corrosion-resistant and long in service period.

Description

technical field [0001] The invention relates to a positioning system, in particular to a floating body positioning system. Background technique [0002] In the traditional floating body positioning system, a simple combination of the floating body, the rope and the anchor point is used, and the floating body always moves around the anchor point through the traction of the rope. In the actual application process of this system, there are many complex problems. First of all, in order to ensure that the positioning system has a certain impact resistance, the ropes are mostly made of heavy metal anchor chains, and the length is longer than the water depth. The metal anchor chain is easy to rust and break easily. Secondly, due to the movement of seawater waves, the floating body is in motion and moves around the bottom anchor point. The longer the rope, the larger the movement range, and the positioning is not accurate enough and the accuracy is low. SUMMARY OF THE INVENTION ...
