Description

Technical Field

[0001] The present invention relates to the technical field of battery detection, and in particular to a simulation detection method for a new energy whole ship power distribution battery system. Background Art

[0002] With the continuous innovation and development of new energy technologies, battery-driven electric propulsion systems have many advantages. The energy utilization efficiency of electric drive is relatively high, which can reduce energy consumption costs in long-term operation and reduce potential safety hazards such as fuel leakage and fire in diesel engine systems.

[0003] At present, new energy ships mostly adopt the battery replacement mode of ship-battery separation. The power batteries on board are usually made into container-mode battery packs, which are convenient for ships to dock at the dock and use the on-site container loading and unloading equipment for direct battery replacement. When the ship encounters bad weather or needs to avoid other ships, the speed can be quickly changed by adjusting the state of the propeller and thruster to ensure safety. Since the mass of the container-mode battery pack used in the ship is large, it is subject to large inertia when the ship speed changes, and the battery pack shell is easily squeezed with the fixed part. In addition, the battery pack is usually installed in the battery compartment of the ship. The waterproof treatment of the compartment can avoid direct contact between the battery pack and water. However, when the ship sails on the water for a long time, the humidity of the air will be high, and there will be more salt spray in the air. If the protection strength of the battery pack is not enough, it is easy to cause water mist and erosion inside the battery pack, affecting the normal use of the battery pack. Therefore, a simulation detection method for the power battery system of the whole new energy ship distribution is proposed. Summary of the invention

[0036] It should be noted that: the battery pack 4 to be tested is placed on the placement plate 7 of the slide 6 by using a lifting mechanical arm. During the slow placement process, the outer shell edge of the battery pack 4 is limited by using the two positioning plates 8 on the placement plate 7.

After the battery pack 4 moves to the set position, the movement of the slide 6 is stopped, and then the propulsion motor 13 is started to drive the main gear 14 to rotate, and the main gear 14 rotates The movement will drive the auxiliary gear rings 15 on both sides to rotate respectively, and the rotation of the auxiliary gear rings 15 will drive the push threaded rod 16 to rotate together, and the push threaded rod 16 will rotate in the threaded sleeve 17, so that the threaded sleeve 17 moves on the threaded rod 16, and the movement of the threaded sleeve 17 will drive the triangular plate 18 and the docking cover 19 fixed to it to move. Since the external threads on both ends of the push threaded rod 16 are in opposite directions, the two docking covers 19 on both sides will move toward each other, and then the docking grooves on the docking covers 19 will be adapted to dock with the docking columns 9 on the placement plate 7, so that the two docking covers 19 can limit and connect the power supply end of the battery pack 4;

[0037] The above advantages are: the rotation of the advancing threaded rod 16 can be used to drive the two docking covers 19 to move toward each other, thereby realizing the limit and power-on test of the battery pack 4, thereby simulating the power-on state of the battery pack 4 when it is fixedly installed, and testing whether it will be affected by subsequent tests in the power-on state;

[0038] The top of the simulated top seat 2 is fixedly connected to a clean water tank 22 through a plurality of fixing rods, the bottom of the clean water tank 22 is connected to two opposite spray covers 41 through a pressurized pipe 23, the bottom of the clean water tank 22 is fixedly connected to a salt water tank 24, the bottom of the salt water tank 24 is connected to a delivery cylinder 25 through a pipeline, the inner end of the delivery cylinder 25 is provided with a sealing cover 28, a one-way flow component is provided on the bottom of the sealing cover 28, and an impeller 34 is provided below the one-way flow component;

[0039] Furthermore, the top ends of the two opposing spray hoods 41 are fixedly connected to the bottom ends of the simulated top seat 2, the bottom ends of the brine tank 24 are connected to the outer ends of the conveying cylinder 25 through pipelines, the top ends of the simulated top seat 2 are fixedly connected to the conveying motor 26, the output ends of the conveying motor 26 are fixedly connected to the spiral blades 27 through the conveying shaft, the spiral blades 27 are rotatably connected to the inner side walls of the conveying cylinder 25, a hydraulic pump is arranged in the clean water tank 22, high-concentration brine is arranged in the brine tank 24, the one-way flow assembly is composed of a filter plate 29, a reset spring 30 and a one-way bead 32, the end of the filter plate 29 is fixedly connected to the side wall of the one-way bead 32 through the reset spring 30, the bottom end of the sealing cover 28 is fixedly connected to the one-way bucket 31, and the inside of the sealing cover 28 and the one-way bucket 31 are connected to each other, the diameter of the one-way bead 32 is slightly larger than the inner diameter of the small mouth end of the one-way bucket 31, the side wall of the sealing cover 28 is fixedly connected to the inner side wall of the pressurized pipe 23, and the inner side wall of the bottom end of the pressurized pipe 23 is rotatably connected to the impeller member 34 through the leak plate 33;

[0040] It should be noted that: the battery pack 4 is then moved to the bottom of the two opposing spray hoods 41 by using the slide 6, and then the hydraulic pump system in the clean water tank 22 is started, and the water flow is passed into the two opposing spray hoods 41 through the pressure pipe 23, and the water flow is sprayed out in a mist-like high pressure, so that the air humidity in the sealing frame 3 increases, simulating the high-humidity use environment of the battery pack 4 on the ship on the river. Under this simulation state, after continuous detection for a period of time, the conveying motor 26 is started to drive the spiral blade 27 to rotate, and the rotation of the spiral blade 27 will spin the high-concentration brine in the brine tank 24 into the sealing cover 28 through the conveying cylinder 25. The space inside the sealing cover 28 causes the hydraulic pressure inside the one-way bucket 31 to continue to increase, so that the hydraulic pressure inside the one-way bucket 31 is greater than the hydraulic pressure outside, and then the one-way ball 32 is pressed, so that there is a gap between the one-way ball 32 and the one-way bucket 31, so that the high-pressure and high-concentration salt water inside the one-way bucket 31 is depressurized and enters the pressurized pipe 23, wherein the impeller 34 at the bottom end of the pressurized pipe 23 continuously rotates under the impact of the flowing liquid, stirring the liquid, so as to facilitate the stirring and mixing of the high-concentration salt water and the fresh water, and form a low-concentration salt water to be sprayed through the counter-spray cover 41, simulating the use environment of the battery pack 4 on the ship in the presence of salt fog on the sea surface;

[0041] The above advantages are as follows: in this way, the opening and closing of the one-way bucket 31 can be used to allow the opposite spray hood 41 to spray water mist and salt mist respectively, simulating the use environment of the battery pack 4 on the river and the sea surface on the ship, respectively, so as to facilitate observation of whether the power supply of the battery pack 4 is affected in this state (i.e., whether the circuit between the battery pack 4 and the docking cover 19 is affected, and whether the output current and voltage of the circuit fluctuate), and to detect the overall corrosion resistance of the battery pack 4;

[0042] A plurality of hydraulic cylinders 35 are arranged above the end of the electric control guide rail 5, and the output end of the hydraulic cylinder 35 is connected to an impact column head 37 through a propulsion seat 36, and both sides of the impact column head 37 are provided with an intrusion detection component;

[0043] Furthermore, the inner end surface of the sealing frame 3 is fixedly connected to the side wall of the hydraulic cylinder 35, the output end of the hydraulic cylinder 35 is fixedly connected to the plane end of the impact column head 37 through the propulsion seat 36, the intrusion detection assembly is composed of a detection sensing plate 39 and a corresponding photoelectric sensor 40, the side wall of the plane end of the impact column head 37 is fixedly connected to the end surface of the detection sensing plate 39 through a telescopic rod 38, and the corresponding photoelectric sensor 40 is fixedly connected to the side wall of the plane end of the impact column head 37;

[0044] It should be noted that: after the above detection is completed, the slide 6 drives the battery pack 4 to continue to move inward, and stops and locks the limit after moving to the end of the electric control guide rail 5. At this time, multiple hydraulic cylinders 35 are synchronously started to push the impact column head 37 on the propulsion seat 36. The hydraulic cylinder 35 is slowly pushed and quickly pushed to simulate the extrusion and impact of the battery pack 4. The change of the propulsion speed of the hydraulic cylinder 35 is the existing technology and will not be described in detail here. During the extrusion and impact process, the detection sensing plate 39 and the impact column head 37 will contact the outer shell of the battery pack 4 synchronously. The detection sensing plate 39 will press the telescopic rod 38 during this process, and the contraction displacement change of the telescopic rod 38 is synchronously consistent with the displacement change of the instantaneous invasion of the impact column head 37. The change in the spacing between the corresponding photoelectric sensor 40 and the detection sensing plate 39 is the displacement change of the telescopic rod 38.

[0045] The above advantages are: in this way, the displacement change detection of the telescopic rod 38 can be used to measure the instantaneous penetration distance of the impact column head 37 during the destructive test, thereby avoiding the situation where the deformation recovery of the material after the destructive test leads to inaccurate measurement of the penetration distance;

[0046] When the present invention is in use, the battery pack 4 to be tested is placed on the placement plate 7 of the slide 6 by using a lifting mechanical arm. During the slow placement process, the outer shell edge of the battery pack 4 is limited by using two positioning plates 8 on the placement plate 7. After the battery pack 4 is initially positioned and placed, the slide 6 on the electric control guide rail 5 is started to drive the battery pack 4 to move into the sealing frame 3, and then the electric push rod 20 is used to drive the sealing plate 21 to move downward to achieve the overall sealing of the sealing frame 3. After the battery pack 4 moves to the set position, the movement of the slide 6 is stopped, and then the propulsion motor 13 is started to drive the main gear 14 to rotate. The rotation of the main gear 14 will respectively drive the auxiliary gear rings 15 on both sides to rotate, and the rotation of the auxiliary gear rings 15 will drive the propulsion threaded rod 16 to rotate together, and the propulsion threaded rod 1 6 rotates in the threaded sleeve 17, so that the threaded sleeve 17 moves on the threaded rod 16. The movement of the threaded sleeve 17 will drive the triangular plate 18 and the docking cover 19 to which it is fixed to move. Since the external threads on the two ends of the advancing threaded rod 16 are in opposite directions, the two docking covers 19 on both sides will move toward each other, and then the docking grooves on the docking covers 19 will be adapted to dock with the docking columns 9 on the placement plate 7, so that the two docking covers 19 can limit and connect the power supply end of the battery pack 4. In this way, the rotation of the advancing threaded rod 16 can be used to drive the two docking covers 19 to move toward each other, so as to realize the limit and power-on test of the battery pack 4, thereby simulating the power-on state of the battery pack 4 when it is fixedly installed, and testing whether it will be affected by subsequent tests in the power-on state;

[0047] Subsequently, the battery pack 4 is moved to the bottom of the two opposing spray hoods 41 by means of the slide 6, and then the hydraulic pump system in the clean water tank 22 is started, and the water flow is passed into the two opposing spray hoods 41 through the pressurized pipe 23, and the water flow is sprayed out in a mist-like high pressure, so that the air humidity in the sealing frame 3 increases, simulating the high-humidity use environment of the battery pack 4 on the ship on the river. Under this simulation state, after continuous detection for a period of time, the conveying motor 26 is started to drive the spiral blade 27 to rotate. The rotation of the spiral blade 27 will spin the high-concentration brine in the brine tank 24 into the space in the sealing cover 28 through the conveying cylinder 25, so that the hydraulic pressure in the sealing cover 28 continues to increase, so that the hydraulic pressure inside the one-way bucket 31 is greater than the external hydraulic pressure, and then the one-way ball 32 is pressed, so that there is a gap between the one-way ball 32 and the one-way bucket 31, so that the one-way The high-pressure and high-concentration salt water inside the bucket 31 is depressurized and enters the pressurized pipe 23, wherein the impeller 34 at the bottom end of the pressurized pipe 23 rotates continuously under the impact of the flowing liquid to stir the liquid, so as to facilitate the stirring and mixing of the high-concentration salt water and the fresh water, and form a low-concentration salt water to be sprayed out through the opposite spray hood 41, simulating the use environment of the battery pack 4 on the ship in the presence of salt fog on the sea surface. In this way, the opening and closing of the one-way bucket 31 can be used to allow the opposite spray hood 41 to spray water mist and salt fog respectively, respectively simulating the use environment of the battery pack 4 on the ship in the river and on the sea surface, so as to facilitate the observation of whether the power-on condition of the battery pack 4 in this state is affected (i.e., whether the circuit between the battery pack 4 and the docking cover 19 is affected, and whether the output current and voltage of this circuit fluctuate), and to detect the overall corrosion resistance of the battery pack 4;

[0048] After the above-mentioned detection is completed, the slide 6 drives the battery pack 4 to continue to move inward, and stops and locks the limit after moving to the end of the electric control guide rail 5. At this time, multiple hydraulic cylinders 35 are synchronously started to push the impact column head 37 on the propulsion seat 36. The hydraulic cylinder 35 is slowly pushed and quickly pushed to simulate the extrusion and impact of the battery pack 4. During the extrusion and impact process, the detection sensing plate 39 and the impact column head 37 will be in contact with the outer shell of the battery pack 4 synchronously. The detection sensing plate 39 will press the telescopic rod 38 during this process. The contraction displacement change of the telescopic rod 38 is synchronized with the displacement change of the instantaneous invasion of the impact column head 37. The change in the spacing between the corresponding photoelectric sensor 40 and the detection sensing plate 39 is the displacement change of the telescopic rod 38. In this way, the displacement change of the telescopic rod 38 can be used to detect the instantaneous invasion distance of the impact column head 37 during the destructive test, so as to avoid the deformation recovery of the material after the destructive test, resulting in inaccurate measurement of the invasion distance.
