Description

Technical Field

[0001] This invention relates to the field of marine batteries, and more particularly to an installation device for a marine vanadium redox flow battery system. Background Technology

[0002] A vanadium redox flow battery system is an energy storage system that stores and releases electrical energy through changes in the valence state of vanadium ions. Its core consists of an electrolyte tank, a fuel cell stack, a circulation pump, and piping. Charging and discharging are achieved through the circulation of the electrolyte between the tank and the stack. In marine applications, tilting (0°-15°) and turbulence are inevitable during ship movement. Existing vanadium redox flow battery systems typically use rubber pads or rigid supports for fixation. Rubber pads have limited deformation and cannot be actively adjusted, while rigid supports completely follow the ship's tilt.

[0003] When the ship tilts, the electrolyte level in the tank shifts with the tilt direction, increasing the level difference between the two sides (when it exceeds 20mm), which can easily cause cavitation at the suction end of the circulation pump. Therefore, there is an urgent need for a fixing device that can actively adjust the angle of the electrolyte tank to ensure the stable operation of the marine vanadium redox flow battery system. Summary of the Invention

[0004] (a) Technical problems to be solved This invention provides an installation device for a marine vanadium redox flow battery system, which aims to solve the technical problem in the prior art that the angle of the electrolyte storage tank cannot be actively adjusted on ships.

[0005] (II) Technical Solution To address the above problems, the present invention provides an installation device for a marine vanadium redox flow battery system, the installation device comprising: a mounting frame, an electrolyte storage tank, and a hydraulic cylinder; The mounting frame includes a mounting base plate disposed on the ship, and the mounting base plate is provided with a hemispherical groove; The first end of the electrolyte storage tank is disposed within the hemispherical groove, and the shape of the first end of the electrolyte storage tank matches that of the hemispherical groove. The electrolyte storage tank can swing within the hemispherical groove. An adjustment plate is also fixedly disposed on the outer wall of the electrolyte storage tank, and the adjustment plate is disposed near the first end of the electrolyte storage tank. The hydraulic cylinder is mounted on the mounting base plate and is located between the mounting base plate and the adjusting plate. The hydraulic cylinder is used to adjust the posture of the electrolyte storage tank.

[0006] Preferably, the adjusting plate is rectangular in shape, and a hydraulic cylinder is provided at each corner of the adjusting plate.

[0007] Preferably, each of the four corners of the adjustment plate is provided with an adjustment groove, and a pulley corresponding to a hydraulic cylinder is slidably disposed in the adjustment groove, and the length direction of the adjustment groove is consistent with the diagonal direction of the adjustment plate; The adjustment plate is equipped with a position sensor for detecting the position of the pulley and a controller for controlling the extension and retraction of the piston rod in the hydraulic cylinder. The position sensor is electrically connected to the controller. The controller is used to control the extension and retraction of the corresponding piston rod in the hydraulic cylinder based on the position information of the pulley in the adjustment groove detected by the position sensor.

[0008] Preferably, the adjustment groove includes an extension section, a balancing section, and a retractable section connected in sequence; The balancing section is located between the extended section and the retracted section, and the balancing section is located at the midpoint of the adjustment groove. The retracted section is located close to the outer wall of the electrolyte storage tank. Multiple position sensors are provided at both the extended section and the retracted section. At both the extended section and the retracted section, the distance between any two adjacent position sensors is less than the diameter of the pulley. When the position sensor detects that the pulley is in the extended section of the adjustment groove, the controller controls the piston rod in the hydraulic cylinder corresponding to the adjustment groove to extend. When the position sensor detects that the pulley is in the retracted section of the adjustment groove, the controller controls the piston rod in the hydraulic cylinder corresponding to the adjustment groove to retract. When the position sensor detects that the pulley is in the balance section of the adjustment groove, the controller controls the piston rod in the hydraulic cylinder corresponding to the adjustment groove to stop moving.

[0009] Preferably, the bottom of the adjustment groove at the balance section is provided with an arc-shaped recess, the shape of which matches the shape of the pulley.

[0010] Preferably, a spring is further provided between the adjusting plate and the mounting base plate, with one end of the spring fixedly connected to the adjusting plate and the other end of the spring fixedly connected to the mounting base plate.

[0011] Preferably, a flexible pad is provided on the bottom surface of the mounting base plate.

[0012] Preferably, the mounting bracket further includes a limiting ring and a plurality of limiting posts. The limiting posts are disposed on the mounting base plate, and the limiting ring is used to connect the plurality of limiting posts. The electrolyte storage tank is located inside the limiting ring, and the limiting ring is disposed near the second end of the electrolyte storage tank.

[0013] (III) Beneficial Effects This invention involves fixing a mounting base plate to a ship, hinged an electrolyte storage tank to the mounting base plate, and installing an adjustment plate on the outer wall of the electrolyte storage tank. Multiple hydraulic cylinders are installed between the adjustment plate and the mounting base plate. The extension and retraction of piston rods within these hydraulic cylinders causes the electrolyte storage tank to oscillate. When the ship is sailing and the electrolyte storage tank tilts on the mounting base plate due to wind and waves, the piston rod in the hydraulic cylinder on the tilted side extends, thereby actively adjusting the angle of the electrolyte storage tank.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0019] In this invention, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0020] This invention provides an installation device for a marine vanadium redox flow battery system. The installation device includes a mounting frame 1, an electrolyte storage tank 2, and a hydraulic cylinder 3. The mounting frame 1 includes a mounting base plate 11 mounted on the ship, and a hemispherical groove 12 is provided on the mounting base plate 11. The first end of the electrolyte storage tank 2 is located within the hemispherical groove 12, and the shape of the first end of the electrolyte storage tank 2 matches that of the hemispherical groove 12, allowing the electrolyte storage tank 2 to swing within the hemispherical groove 12. An adjustment plate 21 is also fixedly mounted on the outer wall of the electrolyte storage tank 2, and the adjustment plate 21 is located near the first end of the electrolyte storage tank 2. The hydraulic cylinder 3 is mounted on the mounting base plate 11, and the hydraulic cylinder 3 is located between the mounting base plate 11 and the adjustment plate 21. The hydraulic cylinder 3 is used to adjust the posture of the electrolyte storage tank 2.

[0021] In the technical solution of this invention, the mounting base plate 11 is fixedly installed on the ship, the electrolyte storage tank 2 is hinged to the mounting base plate 11, and an adjustment plate 21 is provided on the outer wall of the electrolyte storage tank 2. Multiple hydraulic cylinders 3 are arranged between the adjustment plate 21 and the mounting base plate 11. The extension and retraction of the piston rods in the hydraulic cylinders 3 causes the electrolyte storage tank 2 to swing. When the ship tilts on the mounting base plate 11 due to wind and waves during navigation, the piston rod in the hydraulic cylinder 3 on the tilted side extends, thereby leveling the electrolyte storage tank 2. Through the adjustment device driven by the hydraulic cylinders 3, the angle of the electrolyte storage tank 2 can be actively adjusted within the 0°-15° tilt range of the ship, controlling the liquid level difference in the electrolyte storage tank 2 to within 6mm.

[0022] Furthermore, the adjustment plate 21 is rectangular in shape, and a hydraulic cylinder 3 is provided at each corner of the adjustment plate 21. The four hydraulic cylinders 3 can better adjust the posture of the electrolyte storage tank 2.

[0023] Furthermore, each of the four corners of the adjusting plate 21 is provided with an adjusting groove 22, and a pulley 23 corresponding to a hydraulic cylinder 3 is slidably disposed in the adjusting groove 22. The length direction of the adjusting groove 22 is consistent with the diagonal direction of the adjusting plate 21. The adjusting plate 21 is provided with a position sensor for detecting the position of the pulley 23 and a controller for controlling the extension and retraction of the piston rod in the hydraulic cylinder 3. The position sensor and the controller are electrically connected. The controller is used to control the extension and retraction of the piston rod in the corresponding hydraulic cylinder 3 based on the position information of the pulley 23 detected by the position sensor in the adjusting groove 22.

[0024] In the above scheme, by setting adjustment grooves 22 on the adjustment plate 21 and installing sliding pulleys 23 within the adjustment grooves 22, when the electrolyte tank 2 is not tilted, the adjustment plate 21 is in a horizontal state, and the pulleys 23 are stationary within the adjustment grooves 22. At this time, the piston rod in the hydraulic cylinder 3 does not move. When the electrolyte tank 2 tilts, the adjustment plate 21 will be in a tilted state, and the pulleys 23 will slide along the adjustment grooves 22. The position sensor detects the position of the pulleys 23 in the four adjustment grooves 22, and the controller determines which direction the electrolyte tank 2 is tilted. It then controls the corresponding hydraulic cylinder 3 to move, leveling the electrolyte tank 2, making the adjustment plate 21 horizontal, and causing the pulleys 23 to move to the corresponding positions. As described above, this application determines the posture of the electrolyte tank 2 by detecting the positions of the pulleys 23 at the four corners of the adjustment plate 21, and then controls the movement of the corresponding hydraulic cylinders 3, thus achieving leveling of the electrolyte tank 2. The detection method is simple and reliable.

[0025] In a specific implementation, the adjusting groove 22 includes an extended section 221, a balancing section 222, and a retractable section 223 connected in sequence. The balancing section 222 is located between the extended section 221 and the retractable section 223, and is situated at the midpoint of the adjusting groove 22. The retractable section 223 is located near the outer wall of the electrolyte storage tank 2. Multiple position sensors are installed at both the extended section 221 and the retractable section 223. The distance between any two adjacent position sensors at either end of the extended section 221 or the retractable section 223 is less than the diameter of the pulley 23. This ensures that the pulley 23 can be detected by the position sensors regardless of its position within the extended section 221 and the retractable section 223.

[0026] When the position sensor detects that the pulley 23 is in the extended section 221 of the adjustment groove 22, the controller controls the piston rod in the hydraulic cylinder 3 corresponding to the adjustment groove 22 to extend; when the position sensor detects that the pulley 23 is in the retracted section 223 of the adjustment groove 22, the controller controls the piston rod in the hydraulic cylinder 3 corresponding to the adjustment groove 22 to retract; when the position sensor detects that the pulley 23 is in the balanced section 222 of the adjustment groove 22, the controller controls the piston rod in the hydraulic cylinder 3 corresponding to the adjustment groove 22 to stop moving.

[0027] Furthermore, the bottom of the trough at the balance section 222 of the adjusting groove 22 is provided with an arc-shaped recess 24, the shape of which matches the shape of the pulley 23. By providing an arc-shaped recess 24 that matches the shape of the pulley 23, when the ship experiences minor bumps, the pulley 23 will not slip out of the arc-shaped recess 24 and enter the extension section 221 or retraction section 223, thus avoiding frequent operation of the hydraulic cylinder 3 due to minor bumps.

[0028] Finally, a spring 4 is also provided between the adjusting plate 21 and the mounting base plate 11. One end of the spring 4 is fixedly connected to the adjusting plate 21, and the other end of the spring 4 is fixedly connected to the mounting base plate 11. A flexible pad is provided on the bottom surface of the mounting base plate 11. The mounting frame 1 also includes a limiting ring 14 and multiple limiting posts 13. The limiting posts 13 are provided on the mounting base plate 11, and the limiting ring 14 is used to connect the multiple limiting posts 13. The electrolyte storage tank 2 is located inside the limiting ring 14, and the limiting ring 14 is located near the second end of the electrolyte storage tank 2.
