Description

Technical Field

[0001] This invention relates to the field of energy storage equipment technology, specifically to a pulley-type battery unit and energy storage box with quick assembly and disassembly function. Background Technology

[0002] In fields such as new energy storage, emergency power supply, and electric vehicle refueling, energy storage warehouses, as core energy storage carriers, require frequent installation, maintenance, and replacement of internal battery units (energy storage modules). Their disassembly and assembly efficiency and ease of operation directly affect the operation and maintenance costs and response speed of the energy storage system.

[0003] However, energy storage modules in energy storage warehouses are mostly installed by bolt fixing or sliding rail pulling. Disassembly requires manual unscrewing of bolts one by one or overcoming the friction of the sliding rail to pull out the module. The bolt fixing method takes 30-60 minutes for a single disassembly and assembly, and the bolts are prone to loosening due to vibration or corrosion, making disassembly difficult. Although sliding rail pulling is relatively convenient, the module's own weight (usually 50-100kg) can easily cause the sliding rail to wear. After long-term use, the pulling resistance increases, requiring multiple people to operate together. It is difficult to adapt to the needs of automated disassembly and assembly by robotic arms, and the efficiency is extremely low in high-frequency operation and maintenance scenarios such as large-scale energy storage power stations. Summary of the Invention

Two sets of sliding columns a are fixedly connected to the rear end of the side support plate, and both sets of sliding columns a are elastically connected to the inner sidewall of the energy storage shell via a return spring a. A movable plate is hinged to the end of the connecting rod away from the side support plate, and two sets of sliding columns b are fixedly connected to the rear end of the movable plate. Both sets of sliding columns b are elastically connected to the inner sidewall of the rear end of the energy storage shell via a return spring b.

[0008] Preferably, multiple sets of the built-in bracket a are provided, and the multiple sets of built-in bracket a are fixedly connected to the inner side wall of the energy storage shell.

[0014] Preferably, a handwheel is rotatably connected to the rear end of the fixed base.

[0015] This invention provides a pulley-type battery unit and energy storage box with quick assembly and disassembly. It offers the following advantages: 1. This invention solves the pain points of traditional disassembly and assembly relying on manual labor and being inefficient by using a motor, a bidirectional threaded rod, and a hinged lifting structure: During disassembly, the motor drives the bidirectional threaded rod to rotate, causing two sets of threaded blocks to come together. The hinged rod pushes the connecting plate and pulley to lift synchronously, easily lifting the energy storage module and causing the positioning pin to disengage from the through hole of the built-in bracket. The robotic arm can quickly grip and pull it out without manual force. During installation, the motor drives in the opposite direction, and the pulley moves down to disengage from the module, ensuring that the energy storage bracket is stably in contact with the fixed seat.

[0016] 2. This invention solves the installation positioning deviation problem through bidirectional correction and secondary clamping design: During energy storage module installation, the rear end pushes the moving plate, which is pulled together by the connecting rod to bring the side support plates closer together. The contact between the side support plates and the module sidewalls achieves lateral correction; at the same time, the positioning pin is inserted into the through hole of the built-in bracket to limit front-to-back offset. Bidirectional positioning ensures that the module is accurately aligned with the interface; the L-shaped structure formed by the L-block at the front end of the side support plate and the side support plate wraps around the front end of the module to achieve secondary clamping. Combined with the contact support between the energy storage bracket and the fixed seat, it avoids module displacement caused by vibration, reduces the risk of poor electrode contact by more than 90%, and significantly improves the operational stability of the energy storage system. 3. This invention breaks through the customization limitations of traditional energy storage compartments by using standardized built-in brackets and positioning structures: the adaptable design of built-in brackets a / b and energy storage brackets a / b can be compatible with energy storage modules of different brands and specifications, and modules can be replaced without modifying the energy storage compartment, improving the equipment versatility by 80%; at the same time, the rolling contact design of the pulleys and energy storage brackets reduces hard collision damage between the module and the energy storage compartment during disassembly and assembly, and reduces the maintenance frequency of the module shell and the inner wall of the energy storage compartment by 60%.

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0020] Please see the appendix Figure 1 -Appendix Figure 7 This invention provides a pulley-type battery unit and energy storage box with quick disassembly and assembly function, including an energy storage shell 1. An external connector 2 is provided on the side wall at the bottom of the energy storage shell 1. An integral opening and closing door 7 is hinged to the front end of the energy storage shell 1. By opening the integral opening and closing door 7, it is convenient to observe the internal energy storage module 4. A front rotating door 3 is rotatably connected to the front surface of the energy storage shell 1. By opening the front rotating door 3, it is convenient to disassemble, replace and repair the multiple sets of energy storage modules 4 installed inside the energy storage shell 1. The energy storage module 4 can be detachably installed on the inner side wall of the energy storage shell 1 through a lifting disassembly module 5 and an auxiliary positioning module 6. The lifting and disassembly module 5 is used to facilitate the lifting of the energy storage module 4 from the inside of the energy storage housing 1 so that the robotic arm can grip and pull it out. The auxiliary positioning module 6 is used to correct the installation position of the energy storage module 4 when it is installed inside the energy storage housing 1, and to press its front end.

[0021] Furthermore, the lifting and disassembly module 5 includes an internal support a501. An internal support b502 is fixedly connected to the inner sidewall of the energy storage housing 1. Multiple sets of internal supports a501 are provided, and these sets are fixedly connected to the inner sidewall of the energy storage housing 1. The number of internal supports b502 is equal to that of internal supports a501, and they are spaced vertically. Internal supports a501 and b502 are provided on both the left and right sides of the inner side of the energy storage housing 1. Four sets can support and place the energy storage module 4 as a whole. Energy storage supports a504 are fixedly connected to the upper ends of both sidewalls of the energy storage module 4. The lower surface of the energy storage support a504 is in contact with the upper surface of the internal support a501. This contact allows the energy storage module 4 to be placed by its own weight when it is installed into the energy storage housing 1 by the robotic arm. Specifically, the surface of the energy storage bracket a504 has through holes corresponding to the positioning pins 505. The outer wall of the positioning pins 505 is inserted into the inner wall of the through holes of the energy storage bracket a504. This insertion allows the energy storage bracket a504 to move when the energy storage module 4 is inserted into the energy storage housing 1 by the robotic arm. During placement, the positioning pins 505 are inserted into the through holes of the energy storage bracket a504, thus placing the energy storage module 4 stably and preventing lateral displacement. The outer side of the positioning pins 505 has internal thread grooves, which can be tightened with nuts to prevent vertical shaking during transportation. The upper surface of the internal bracket a501... Multiple sets of positioning pins 505 are fixedly connected to the surface. Energy storage brackets b506 are fixedly connected to the lower ends of both side walls of the energy storage module 4. A fixed seat 503 is fixedly connected to the upper surface of the built-in bracket b502. A motor 507 is fixedly connected to the side wall of the fixed seat 503. A bidirectional threaded rod 508 is fixedly connected to the output shaft of the motor 507. The bidirectional threaded rod 508 is existing technology, and its surface is provided with two sets of threads with opposite directions of rotation. Driven by the motor 507, the bidirectional threaded rod 508 can be rotated, so that the two sets of threaded blocks 509 move closer or further apart on its surface. The bidirectional threaded rod 508 is rotatably connected to the inner side wall of the fixed seat 503, and the threaded blocks 509 slide. Connected to the inner sidewall of the fixed base 503, the pulley 512 contacts the lower surface of the energy storage bracket b506. This contact allows the energy storage module 4 to be disassembled during the process. The movement of the threaded block 509 causes the hinge rod 510 to push the connecting plate 511 and the pulley 512 upwards simultaneously. At this time, the energy storage bracket a504 and the positioning pin 505 disengage from the surface and through hole of the inner bracket a501, facilitating the removal of the energy storage module 4 by the robotic arm. Furthermore, when the energy storage module 4 is installed inside the energy storage housing 1, the reverse movement of the threaded block 509 causes the hinge rod 510 to push the connecting plate 511, which in turn moves the pulley 512 outwards. This allows the release pulley 512 to disengage from the energy storage bracket b506, allowing the lower surface of the energy storage bracket b506 to contact the surface of the fixed base 503, thereby increasing overall stability. Simultaneously, the lower surface of the energy storage bracket b506 has a guide groove that engages with the pulley 512, guiding the pulley 512. The upper surface of the fixed base 503 contacts the lower surface of the energy storage bracket b506. A threaded block 509 is threadedly connected to the surface of the bidirectional threaded rod 508. A hinge rod 510 is hinged to the upper surface of the threaded block 509. A connecting plate 511 is hinged to the end of the hinge rod 510 away from the threaded block 509. The pulley 512 is rotatably connected to the inner sidewall of the connecting plate 511.

[0022] Furthermore, the auxiliary positioning module 6 includes a side support plate 601. One end of the side support plate 601 is hinged to a connecting rod 605, and the other end of the side support plate 601 is fixedly connected to an L-block 602. The L-block 602 and the front end of the side support plate 601 form an L-shape, which can clamp the front end of the energy storage module 4, increasing secondary stability during installation. The rear end of the side support plate 601 is fixedly connected to two sets of sliding columns a603. Both sets of sliding columns a603 are elastically connected to the inner side wall of the energy storage shell 1 through a return spring a604. One end of the return spring a604 is fixedly connected to the sliding column. On the rear surface of a603, the other end of the return spring a604 is fixedly connected to the inner sidewall of the energy storage housing 1. The function of the return spring a604 is to automatically reset the position of the sliding column a603 after it moves with the side support plate 601. The sliding column a603 is slidably connected to the inner sidewall of the energy storage housing 1, and the outer wall of the side support plate 601 is in contact with the outer sidewall of the energy storage module 4. The contact between the two allows the energy storage module 4 to be uprighted by the two sets of side support plates 601 when it is grasped and installed into the energy storage housing 1 by the robotic arm, thus avoiding installation errors. When the mounting position shifts, the outer wall of block L602 contacts the front surface of energy storage module 4. A movable plate 606 is hinged to the end of connecting rod 605 away from side support plate 601. Two sets of sliding posts b607 are fixedly connected to the rear end of movable plate 606. Both sets of sliding posts b607 are elastically connected to the inner side wall of the rear end of energy storage housing 1 via return springs b608. One end of the return spring b608 is fixedly connected to the rear end of sliding post b607, and the other end is fixedly connected to the inner wall of the rear end of energy storage housing 1. The function of the return spring b608 is to control the sliding post b607. 07. The position is automatically reset after the moving plate 606 moves. The sliding column b607 is slidably connected to the inner wall of the rear end of the energy storage housing 1. The front surface of the moving plate 606 is in contact with the rear surface of the energy storage module 4. The contact between the two makes the rear end of the energy storage module 4 contact the moving plate 606 when the robot arm grabs it, and pushes the moving plate 606 to move. This allows the moving plate 606 to pull the corresponding side support plates 601 closer together through two sets of inclined hinged connecting rods 605, thereby straightening the installation position of the energy storage module 4.

[0023] Working principle: When the energy storage module 4 is installed into the energy storage housing 1 by the robotic arm, the rear end of the energy storage module 4 first contacts the front surface of the moving plate 606. As the installation progresses, it pushes the moving plate 606 backward, causing the two sets of sliding columns b607 to slide synchronously and compress the return spring b608. The moving plate 606 pulls the side support plate 601 through the connecting rod 605 hinged at both ends, causing the side support plate 601 to move closer to the energy storage module 4. At this time, the sliding column a603 at the rear end of the side support plate 601 compresses the return spring a604, and the two sets of side supports... Plate 601 achieves installation position correction by contacting the outer sidewall of the energy storage module 4; at the same time, the energy storage brackets a504 on both sides of the energy storage module 4 move with the module, and the positioning pins 505 on their lower surfaces are inserted into the corresponding through holes on the surface of the built-in bracket a501 to ensure that the module does not shift left or right, and the lower surface of the energy storage bracket b506 finally contacts the upper surface of the fixing seat 503; and the L-shaped block 602 at the front end of the side support plate 601 forms an L-shaped structure with the side support plate 601, which surrounds the front end of the energy storage module 4 to complete secondary fixation and ensure installation stability.

[0024] When it is necessary to disassemble the energy storage module 4, first open the overall opening and closing door 7, and then, depending on the actual need, disassemble which energy storage module 4. Then, rotate and open the front rotating door 3 at the front end of the energy storage housing 1, start the motor 507 on the side wall of the fixed base 503, and the output shaft of the motor 507 drives the bidirectional threaded rod 508 to rotate. Because the surface of the bidirectional threaded rod 508 has two sets of threads with opposite directions, the two sets of threaded blocks 509 connected by the threads on their surfaces approach each other along the inner side wall of the fixed base 503. Through the hinge rod 510 hinged on the upper surface, the connecting plate 511 is pushed upward, and the pulley 512 on the inner side of the connecting plate 511 moves upward. The energy storage module 4 moves upward and contacts the lower surface of the energy storage bracket b506; the continuous lifting causes the lower surface of the energy storage bracket a504 to detach from the upper surface of the built-in bracket a501, and the positioning pin 505 is pulled out from the inside of the energy storage bracket a504. At this time, the energy storage module 4 is lifted up as a whole, making it easy for the robot arm to reach in, grip, and pull out; during the installation process, the motor 507 drives the bidirectional threaded rod 508 to rotate in the opposite direction, the threaded blocks 509 move away from each other, the hinge rod 510 pulls the connecting plate 511 and the pulley 512 to move downward, and the pulley 512 disengages from the energy storage bracket b506, ensuring that the energy storage bracket b506 is stably in contact with the fixed seat 503. Example

[0025] Reference Figure 8 The rear end of the fixed base 503 is also rotatably connected to a hand crank 513. By setting the hand crank 513, the overall structure can reduce electrical interference according to different transportation conditions.

[0026] Working principle: The hand crank 513 drives the bidirectional threaded rod 508 to rotate. Since the surface of the bidirectional threaded rod 508 has two sets of threads with opposite directions, the two sets of threaded blocks 509 connected by the threads on their surfaces approach each other along the inner side wall of the fixed seat 503. The hinge rod 510 hinged to the upper surface pushes the connecting plate 511 to move upward. The pulley 512 on the inner side of the connecting plate 511 moves upward synchronously and contacts the lower surface of the energy storage bracket b506, thereby lifting the energy storage module 4.
