Description

Technical Field

[0001] The invention relates to the field of ship side thrust, and in particular to a side thrust cover energy-saving device. Background Art

[0002] At present, the side thrust capping energy-saving device is mainly used in special-purpose ships such as scientific research ships. For ships equipped with side thrusters, if the side thruster drag and noise reduction capping device is not installed, the original hull linearity is easily affected. During the navigation process, it will generate additional resistance and bubbles due to the incomplete hull linearity, affecting the speed and interfering with the sonar equipment. The existing side thrust capping energy-saving devices include grid plate type, door type, and rotary vane cylinder type, among which the grid plate type is more widely used in engineering. The grating type mainly uses a mechanism to push multiple gratings to complete synchronous opening and closing. Its advantages are easy disassembly and maintenance. The cover itself has a simple structure and has little impact on the thruster. The disadvantages are that the overall structure is complex, there are many parts, and the probability of failure during use is high. The grating structure is prone to foreign matter entanglement during use; the door-type cover mainly completes opening and closing by pushing the cover to move along the hull cross-section. Its advantages are simple structure and stable function. The disadvantage is that the structure is relatively large, requires a larger installation space, and requires a larger force to complete the opening and closing action; the rotary vane cylinder type mainly completes the opening and closing action by driving a circular single plate to rotate through a transmission shaft. Its advantages are simple structure and relatively stable performance. The disadvantage is that the cover is designed to be circular and cannot adapt to the complex shape of the ship. Therefore, it is urgent to design a new side thruster cover energy-saving device. Summary of the invention

[0024] In the attached drawings: a side thrust capping energy-saving device, comprising a hull plate 4, a cap 7, and a cylinder 1; characterized in that: the hull plate 4 is arranged as an arc-shaped surface, a through hole 4-1 is arranged on the hull plate 4, the cylinder 1 is connected and fixed to the hull plate 4 by welding, and the cylinder 1 is arranged on the concave side of the hull plate 4 and communicates with the through hole 4-1; a first rib plate 8 and a second rib plate 9 perpendicular to each other are also arranged between the cylinder 1 and the hull plate 4; so that the connection between the cylinder and the hull plate is more stable and the structural stability is better; a cylinder bracket 6 is arranged outside the cylinder 1, one end of the cylinder a5 is connected to the cylinder bracket 6, and the other end is connected to the connecting rod 3; the cylinder a5 and the cylinder bracket 6, and the cylinder a5 and the connecting rod 3 are all arranged to be hinged; The cover 7 is connected to the connecting rod 3 through a pin mechanism, and the position of the cover 7 corresponds to the position of the through hole of the cylinder 1; so that when the cover is closed, the through hole of the hull plate is just blocked; the effect of reducing energy consumption and noise is achieved; the inner surface of the cover 7 is provided with a lining plate 7-1 to effectively prevent the cover plate from deforming; the lining plate 7-1 is symmetrically provided with ear seats 7-2 on both sides; the pin mechanism includes a first pin 13 and a second pin 12, the first pin 13 and the second pin 12 are symmetrically arranged on the cylinder 1, one end of the first pin 13 is arranged in the hole of the ear seat 7-2, and the other end passes through the cylinder wall and is arranged outside the cylinder 1; one end of the second pin 12 is arranged in the hole of another ear seat 7-2, and the other end is connected to the connecting rod 3; the setting of the ear seat facilitates the cover plate to be turned over. The cover 7 is set as an arc surface, and the curvature matches the curvature of the hull plate 4. It ensures that the original line of the hull can be completely maintained when the sealing plate is closed, reduces the extra resistance and foaming caused by the incomplete line of the hull, and achieves the effect of energy saving, emission reduction and noise reduction. The cylinder 1 is also provided with a locking seat 10, and the limit plate 10-1 of the locking seat 10 is set in a fan shape, and the limit plate 10-1 is provided with two limit holes 10-2; the connecting rod 3 is provided with a locking mechanism 2, the locking mechanism 2 includes a locking pin 2-1 and a cylinder b2-2 for locking the pin, and the locking pin 2-2 of the locking mechanism 2 cooperates with the limit hole 10-2; it is used to position the rotation angle of the shaft pin and limit the opening or closing of the sealing plate.

[0025] The first pin shaft 13 and the second pin shaft 12 are both provided with sleeves 11 outside, bushings 14 are provided between the first pin shaft 13 and the sleeve 11 and between the second pin shaft 12 and the sleeve 11, and a skeleton oil seal 15 is provided at one end of the bushing 14.

[0027] In specific implementation, the device door and connecting cylinder are installed at the entrance and exit of the ship's thruster channel. They can be electrically controlled, controlled by an accumulator, or manually controlled. The action of the cylinder a that rotates the connecting rod and the cylinder b that locks the latch is actuated by high-pressure oil provided by the hydraulic pump station, and the extension and retraction of the cylinder are remotely controlled by controlling the solenoid valve. When the pump station fails to work, the sealing plate is opened by manually controlling the accumulator to ensure the normal operation of the thruster. The end stroke of the cylinder a that rotates the connecting rod is equipped with an induction switch, which can determine whether the sealing cover is open or closed. The oil cylinder b for locking the latch is provided with an inductive switch at the end stroke, by which it can be determined whether the latch is inserted; when the cover plate is opened or closed in place, the sensor will give a signal to the locking oil cylinder b, and the locking latch will be inserted or pulled out; the cylinder body acts as a support in the entire device; the oil cylinder bracket is fixed on the mounting cylinder body and acts as a fixed hinge, supporting the pin shaft and the oil cylinder a to rotate around their rotation center; the oil cylinder a is connected to the transmission arm, pushing the transmission arm to rotate around its rotation center; when the oil cylinder is started, the oil cylinder will push the transmission arm to rotate, thereby driving the pin shaft and the cover plate fixed on the pin shaft to rotate.

[0028] When manufacturing the device, the cover line shape must be consistent with the hull plate line shape; at the same time, ensure that the gap between the cover and the cylinder can enable the cover to be turned over smoothly.

[0029] The device is designed to have a service life of more than 20 years and can withstand long-term immersion in seawater and erosion by marine organisms without being damaged. The entire cover device does not affect the normal operation of the ship's thruster when it is opened, and can basically maintain the original linearity of the hull when it is closed, ensuring that the ship is not affected when sailing at full speed.

For those skilled in the art, other different forms of changes or modifications may be made based on the above descriptions.
