Description

TECHNICAL FIELD

[0001] The application discloses the technical field of anchor throwing equipment, and particularly relates to an anchor throwing speed limiting device for a ship anchor machine. BACKGROUND

[0002] The ship anchor machine is a core equipment for controlling the releasing and winding of the anchor chain in the ship berthing operation, and the anchor throwing function is realized by releasing the anchor chain to make the ship anchor sink to the seabed by gravity to position the ship. In the free anchor throwing process, the gravity acceleration of the anchor and the anchor chain can cause the falling speed to be out of control. The traditional anchor machine applies the acceleration limitation to the anchor chain through the mechanical brake device or the hydraulic damping system, and the modern intelligent speed limiting technology realizes the precise speed regulation through the cooperative action of the speed sensor, the PLC controller and the electro-hydraulic proportional valve, thereby effectively avoiding the safety hazards such as the accumulation of the anchor chain, the overload of the anchor machine and the impact of the anchor head on the seabed. However, the existing technology generally focuses on the stability and response speed of the speed control itself, and lacks effective treatment schemes for the huge gravity potential energy conversion problem in the anchor throwing process. When the several-ton anchor chain falls at the controlled speed, the gravity potential energy and kinetic energy are completely converted into friction heat energy dissipation through the brake system, which not only causes the substantial waste of the ship energy, but also aggravates the thermal degradation effect of the brake parts, forcing the system to be equipped with an additional heat dissipation device. Under the background of the rapid development of the ship energy saving and emission reduction technology, this one-way energy loss mode has been difficult to meet the design requirements of the green ship, and it is urgent to develop an anchor throwing speed limiting system with the energy regeneration function to realize the kinetic energy recovery and recycling.

[0013] Compared with the prior art, the present application has the following beneficial effects:

[0014] (1) The present application realizes dynamic speed regulation and energy recycling in the anchor throwing process through the innovative mechanical energy storage system, and the core lies in that the anchor chain drives the matching chuck to rotate when the anchor chain is lowered, and the two groups of energy storage assemblies are synchronously actuated. When the anchor chain is accelerated to fall under the action of gravity, the gear and rack transmission of the chuck converts the rotary motion into the vertical displacement of the energy storage assembly, wherein the adjustable counterweight box is lifted along the guide column to stretch the high-stiffness spring, and the mass of the counterweight block and the spring stiffness are coupled to form a nonlinear damping characteristic. Under the double superposition of the spring elastic potential energy and the gravitational potential energy of the adjustable counterweight box, a gradual resistance torque opposite to the movement direction of the anchor chain is generated, so that the rotating speed of the chuck is stabilized within the preset threshold, and the free-fall trend of the anchor chain is effectively inhibited. In this process, the kinetic energy of the falling anchor chain is converted into the stored mechanical potential energy in real time, which not only avoids the heat energy loss generated by the traditional braking, but also forms a closed-loop speed regulation mechanism through the real-time feedback of the spring deformation and the displacement of the adjustable counterweight box, so that the adaptive and accurate control of the anchor throwing speed is realized. After the anchor throwing is completed, the energy storage assembly is reset under the driving of the spring rebound force and the self-weight of the adjustable counterweight box, and the released potential energy is converted into electric energy by the bidirectional hydraulic pump or the rotary generator, and is fed back to the ship power grid, or is stored in the flywheel system for reuse in the anchor lifting operation. The passive speed regulation is realized through the inherent characteristics of the mechanical structure, and the redundant braking protection is formed in cooperation with the electric control system, so that the reliability and energy efficiency ratio of the anchor windlass in complex sea conditions are significantly improved, and the present application is especially suitable for the precise speed control requirement of the large-mass lowering of the long anchor chain in deep-sea anchoring operation.

[0015] (2) Through the technical scheme of the present application, the short slot rotation drives the first pinion and the second pinion to drive the rack to move upward, the speed reducer reduces the speed, and the rotating direction is controlled, finally driving the rack and the adjustable counterweight box to rise and store energy, and in this process, the spring assembly is stretched to store energy, which can provide power when the anchor chain is recovered, and save a certain amount of energy.

[0016] (3) Through the technical scheme of the present application, when the matching chuck rotates, it drives the inner disc, and the inner disc drives the transmission disc, and then drives the water pump to pump water. The resistance generated by pumping water will also limit the rotating speed of the matching chuck.

[0017] (4) Through the technical scheme of the application, the faster the speed of the cooperating chuck, the more water pumps are driven, more seawater can be pumped, the falling of the pumped water can provide power when the anchor chain is recovered, and the centrifugal springs with different elastic forces can increase the resistance according to the speed, the faster the speed, the greater the resistance, and the more the energy storage.

Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort belong to the scope of the present application.

The bottom mounting plate 1 is fixedly provided with a first support plate 13, a second support plate 33 and a third support plate 34. The first support plate 13 is provided with an energy storage assembly one, and the second support plate 33 is provided with an energy storage assembly two. Different energy storage assemblies are provided on both sides of a cooperating chuck 3. The energy storage assembly one stores energy through a spring and a lifting weight, so as to control the force and further control the rotating speed of the cooperating chuck 3. The energy storage assembly two stores energy through pumped storage. The resistance of the pumped storage is fixed, so that the main function of the energy storage assembly two is to store energy. The energy storage assembly two has an influence on the rotating speed but is not convenient to control. The rotating speed is mainly controlled by the energy storage assembly one. The cooperating chuck 3 is provided between the first support plate 13 and the second support plate 33. The cooperating chuck 3 is provided with a groove. An anchor chain cooperates with the groove to drive the cooperating chuck 3 to rotate.

Through the above technical solution, when the anchor is thrown, the chain drives the cooperating chuck 3 to rotate, the cooperating chuck 3 drives the two energy storage assemblies to store energy, and the rotating speed of the cooperating chuck 3 is controlled through the energy storage assemblies, so as to prevent the anchor chain from sinking too fast and losing control, thereby causing damage.

[0030] In the present embodiment, the energy storage assembly one includes a counterweight sleeve 8, and an adjustable counterweight box 6 is slidably provided on the counterweight sleeve 8. A plurality of springs are fixedly provided between the adjustable counterweight box 6 and the bottom mounting plate 1. The cooperating chuck 3 drives the adjustable counterweight box 6 to rise, and the spring is pulled to store energy.

The lower end hook of the tension spring is fixed by a locking pin shaft in each mounting ring. The pin shaft and the mounting ring are prevented from loosening by a split pin.

This design enables the tension spring to be lengthened and stored when the anchor is thrown, and to rely on the elastic contraction force to assist energy recovery when it is reset, while the guide rod and the linear bearing ensure the movement accuracy and durability.
