Description

Technical Field

[0001] This utility model relates to the technical field of marine pump devices, specifically to a marine pump shock absorption and anti-tilting device. Background Technology

[0002] Marine pumps refer to various pumps used on ships that meet the requirements of ship specifications and technical specifications. On board, they are frequently used to transport various liquids such as seawater, fresh water, sewage, lubricating oil, and fuel oil, making them indispensable key equipment in ship operation. During navigation, ships are subjected to various external forces such as waves, currents, and wind, causing the hull to frequently tilt at different angles. Since marine pumps are usually fixed to the hull, the tilting of the hull will cause the pumps to also tilt. When a marine pump is tilted, the relative position between its internal rotating components, such as the impeller, and the pump casing will shift, easily leading to friction and collision, and consequently, damage to the components.

[0003] Currently, traditional marine pump anti-roll devices have certain limitations. These devices generally require gyroscopes to monitor the ship's tilt state, and then rely on position correction equipment such as electric push rods to power the marine pump mounting platform for adjustment to restore it to a level position. This method not only requires an additional power unit to provide energy, increasing the ship's energy consumption, but also depends on the coordinated operation of electronic monitoring and the power drive system. If any link in this chain fails, the entire anti-roll device may fail, and its operational reliability needs to be improved. Utility Model Content

[0004] (I) Technical Issues

[0005] This invention provides a marine pump shock absorption and anti-tilting device that requires no power unit, relies on mechanical principles to automatically adjust the marine pump to a horizontal state according to the tilt of the hull, and has a shock absorption function, so as to solve the problems of high energy consumption and low reliability of traditional anti-tilting devices.

[0006] (II) Technical Content

[0007] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: a marine pump shock absorption and anti-tilting device, including a base, which is fixed to the ship deck by bolts. A bearing platform is connected to the upper end face of the base through a shock absorption component. Anti-tilting brackets are fixed on both the front and rear sides of the upper end face of the bearing platform. The upper end of the anti-tilting bracket is concave arc-shaped, and a swing trolley is slidably connected between the two anti-tilting brackets. An installation platform for installing the marine pump is fixed on the upper end of the swing trolley. An arc-shaped groove plate is fixed inside the arc surface of the upper end of the anti-tilting bracket. The arc groove plate has a slot for the roller shaft of the swing trolley to pass through and fit with clearance. The roller of the swing trolley rolls along the arc surface of the upper end of the anti-tilting bracket.

[0008] Furthermore, the damping assembly includes dampers fixedly installed on the upper end face of the base and at the four corners of the bottom of the support platform, and springs are sleeved on the outside of the dampers.

[0009] Furthermore, a damping rod is hinged at the center of the upper end of the support platform, and the piston end of the upper end of the damping rod is hinged to the bottom of the swing trolley.

[0010] Furthermore, the base has mounting holes on both the left and right sides for fixing to the ship's deck, and the mounting platform has fixing holes at the top for installing a marine pump.

[0011] Furthermore, two roller shafts are fixedly provided at both the front and rear ends of the swing trolley, and a roller is rotatably provided at the other end of each roller shaft.

[0012] (III) Technical Effects

[0013] Compared with existing technologies, this invention has the following advantages: This device eliminates the need for electronic monitoring components such as gyroscopes and power drive units such as electric push rods. It relies entirely on mechanical structures to automatically adjust the horizontal state of the installation platform according to the ship's tilt, requiring no additional energy consumption and significantly reducing the ship's energy consumption, aligning with the trend of energy conservation and emission reduction. Since the anti-tilting function is achieved entirely through mechanical principles, it avoids the potential failure risks that may arise from the coordinated operation of electronic monitoring and power drive systems, greatly improving the stability and reliability of the device's operation. By installing a shock-absorbing component consisting of dampers and springs between the base and the support platform, vibrations generated during ship navigation can be effectively buffered, reducing the impact of vibrations on the marine pump. The arc-shaped design at the upper end of the anti-tilting bracket, in conjunction with the rollers of the swing trolley, allows the swing trolley to slide smoothly along the arc surface, achieving automatic horizontal adjustment of the installation platform, making it suitable for widespread application on various types of ships.

[0024] Combined with appendix Figure 1 To be continued Figure 6 A marine pump shock absorption and anti-tilting device includes a base 1, which is fixed to the ship's deck by bolts. A support platform 3 is connected to the upper surface of the base 1 through a shock absorption component 2. Anti-tilting brackets 4 are fixed on both the front and rear sides of the upper surface of the support platform 3. The upper end of the anti-tilting bracket 4 is concave arc-shaped, and a swing trolley 5 is slidably connected between the two anti-tilting brackets 4. An installation platform 6 for installing the marine pump is fixed on the upper end of the swing trolley 5. An arc-shaped groove plate 7 is fixed inside the arc surface of the upper end of the anti-tilting bracket 4. The arc-shaped groove plate 7 has a slot 8 for the roller shaft 14 of the swing trolley 5 to pass through and be clearance-fitted. The roller 15 of the swing trolley 5 rolls along the arc surface of the upper end of the anti-tilting bracket 4. Two roller shafts 14 are fixed at both the front and rear ends of the swing trolley 5, and the other end of each roller shaft 14 is rotatably equipped with the roller 15.

[0025] In this embodiment, as a preferred technical solution, the shock absorption component includes dampers 9 fixedly disposed on the upper end face of the base 1 and at the four corners of the bottom of the support platform 3, and springs 10 are sleeved on the outside of the dampers 9.

[0026] In this embodiment, as a preferred technical solution, a damping rod 11 is hinged at the center of the upper end of the support platform 3, and the piston end of the upper end of the damping rod 11 is hinged to the bottom of the swing trolley 5.

[0027] In this embodiment, as a preferred technical solution, the base 1 is provided with mounting holes 12 on both the left and right sides for fixing to the ship deck, and the mounting platform 6 is provided with fixing holes 13 on the upper end for installing a marine pump.

[0028] The working principle of this utility model is as follows: First, the base 1 is fixed to the ship's deck by bolts and mounting holes 12 on both sides, providing a stable installation foundation for the entire device. The marine pump is installed on the installation platform 6, which is fixedly connected to the marine pump through the fixing hole 13 at the upper end and moves together with the swing trolley 5. When the ship tilts during navigation, the anti-tilt bracket 4 tilts synchronously with the support platform 3. Since the swing trolley 5 rolls along the arc-shaped surface at the upper end of the anti-tilt bracket 4 through the rollers 15 at both ends, and the roller shaft 14 of the swing trolley 5 passes through the slot hole 8 on the arc-shaped groove plate 7 with clearance fit, the swing trolley 5 will slide relative to the anti-tilt bracket 4 under the action of gravity. This sliding allows the installation platform 6 to automatically adjust its position and always maintain a horizontal state, thereby ensuring that the marine pump installed on it is in a horizontal working state and realizing the anti-tilt function. At the same time, during the sliding process of the swing trolley 5, the damping rod 11 can play a buffering and damping role, preventing the swing trolley 5 from excessively swinging due to inertia and enhancing the stability of the device. When vibrations occur during ship navigation, the damping components 2 at the four corners between the base 1 and the support platform 3 play a role in effectively reducing the transmission of vibration to the support platform 3 and the components above it, reducing the impact of vibration on the marine pump, and achieving the damping function.

[0029] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
