Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings in conjunction with the following detailed description. It should be understood that the description is intended to be exemplary only, and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.
Example 1: when the submerged buoy 3 is stable, the cable 5 rises under the action of the buoyancy of the floating ball 4, and because the length of the cable 5 between the weight 7 and the submerged buoy 3 is fixed, after the floating ball 4 rises to a certain height, the floating ball 4 tends to be stable under the action of the buoyancy of the floating body 6 with the sliding block and the submerged buoy 3, and the cable 5 between the floating ball 4 and the submerged buoy 3 is in a tensioned state.
Example 2: when the submerged buoy 3 releases the steel cable 2, the submerged buoy 3 rises due to self buoyancy, the cable 5 is driven at the same time, the cable 5 at the right end of the floating body 6 with the pulley moves towards the left end through the pulley, after the cable reaches the specified depth, the cable 5 and the steel cable 2 cannot be wound due to the fact that the cable 5 at the rising process is in a tensioning state under the buoyancy effect of the submerged buoy 3 and the floating ball 4.
Example 3: when the work of the submerged buoy 3 is finished, the steel cable 2 is recovered, because the submerged buoy 3 is in a tensioned state when the cable 5 works, after the submerged buoy descends, the buoyancy of the submerged buoy 3 temporarily cannot exert a powerful effect on the cable 5, the cable 5 is loosened, meanwhile, under the action of the buoyancy of the floating ball 4, the left cable 5 with the pulley floating body 6 is pulled to the right side through the pulley, the redundancy of the left cable 5 is reduced, in the process, the length of the cable 5 with one end of the steel cable 2 can be always met under the action of the fluid force, the left cable 5 is always not wound with the steel cable 2, and after the descending depth is reached, under the action of the buoyancy of the submerged buoy 3 and the floating ball 4, the cable 5 is tensioned again.
Example 4: referring to fig. 3, the floating body 6 with the pulley consists of a pulley block 6-1, a floating body 6-2, a connecting steel cable 6-3 and a counterweight body 6-4. The upper end of the floating body 6-2 is provided with a pulley block 6-1, and the lower end is connected with the counterweight body 6-4 through a steel cable 6-3. Because the underwater silt is accumulated and has larger depth, if rigid connection is adopted, equipment for installing the pulley block 6-1 has to be prepared to a certain height to ensure that the pulley is not buried in the silt, meanwhile, the weight of the equipment is larger, the recovery is inconvenient for a submerged buoy, the height of the pulley block 6-1 can meet the condition of the deep silt by connecting the counterweight body 6-4 with the floating body 6-2, the weight is lighter, and the recovery is convenient.
It is to be understood that the above-described embodiments of the present invention are merely illustrative of or explaining the principles of the invention and are not to be construed as limiting the invention. Therefore, any modification, equivalent replacement, improvement and the like made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention. Further, it is intended that the appended claims cover all such variations and modifications as fall within the scope and boundaries of the appended claims or the equivalents of such scope and boundaries.
