Description

Technical Field

[0001] This utility model relates to the field of energy storage technology, and in particular to a universal liquid-cooled battery pack installation device for the energy storage industry. Background Technology

[0002] An energy storage cabinet is the basic unit of energy storage equipment. A single energy storage cabinet can store up to 5,500 kilowatt-hours of electricity per day, much like a large power bank, equivalent to the daily electricity consumption of over 500 households. The working principle of an energy storage cabinet is that within a power system, it releases the stored energy when needed to balance the voltage and frequency of the power grid. An energy storage cabinet typically consists of an energy storage device, a converter, and a control system, possessing the ability to absorb and release energy. The main function of an energy storage cabinet is to convert electrical energy into another form of energy through the energy storage device and store it. Then, when needed, the converter converts it back into electrical energy and transmits it to the required electrical equipment through the power grid.

[0003] Energy storage cabinets are integrated energy storage systems developed to meet the needs of the mobile energy storage market. They feature simplified infrastructure construction costs, short construction cycles, high modularity, and ease of transportation and installation. They are suitable for applications such as thermal power, wind power, solar power, and other power plants, as well as islands, residential areas, schools, research institutions, factories, and large load centers.

[0004] The relatively compact spacing of energy storage cabinets on project sites results in limited space for battery pack maintenance and disassembly. Most existing energy storage cabinets cannot be used in confined spaces. Therefore, it is necessary to develop a universal liquid-cooled battery pack installation device for the energy storage industry that can cope with use in confined spaces. Summary of the Invention

[0005] The purpose of this utility model is to solve the technical problem that the current energy storage cabinets are arranged in a relatively compact manner on the project site, resulting in limited space for battery packs during maintenance and disassembly of the energy storage cabinets, and that most existing energy storage cabinets cannot be used in confined spaces. The present invention provides a universal liquid-cooled battery pack installation device for the energy storage industry to solve the above-mentioned technical problems.

[0006] A general-purpose liquid-cooled battery pack installation device for the energy storage industry is characterized by comprising a PLC control cabinet, a battery pack support fixture, a support mechanism, a drive device, mechanical grippers, limit sensors, heavy-duty feet, a forklift hole device, and guide rails. The PLC control cabinet is located at one end of the battery pack support fixture. The drive device consists of a lead screw module, a driver, a servo motor, and a cable chain. The battery pack support fixture consists of a guide wheel assembly, universal balls, and a support base. The lead screw module is assembled inside the upper part of the support base. The guide rail is assembled inside the upper part of the support base. The universal balls are assembled on both sides of the inner wall of the support base. The guide wheel assembly is assembled on both outer walls of the support base. The mechanical grippers are slidably assembled on the guide rails and the lead screw module. Limit sensors are assembled at both ends of the support base. The heavy-duty feet are assembled at the bottom of the support base. The forklift hole device is assembled at the bottom of the support base and consists of fork tooth fixing bolts and a fork tooth frame.

[0007] Furthermore, in order to reduce the overall weight of the liquid-cooled battery pack installation equipment, the PLC control cabinet adopts an overhead design. On the one hand, this can reduce the overall weight of the liquid-cooled battery pack installation equipment, and on the other hand, it does not affect the reciprocating motion of the lead screw module.

[0008] Furthermore, the omnidirectional balls and guide wheel assemblies are arranged in a staggered manner, with the number of omnidirectional balls being 2.5-3 times the number of guide wheel assemblies.

[0009] Furthermore, the length of the battery pack support fixture is 1000-2400 mm, the width is 500-1400 mm, and the height is 150-500 mm.

[0010] Furthermore, the fork tooth fixing bolt is an adjusting bolt, and the fork tooth fixing bolt is distributed at the bottom and one side of the fork tooth frame. The fork tooth fixing bolt is an adjustable fixing bolt.

[0011] Furthermore, the number of heavy-duty foot cups is 6-8, and the number of forklift hole devices is 2.

[0012] Furthermore, to ensure the accuracy of battery pack disassembly and installation, the guide rails are arranged in four columns, the lead screw modules are arranged in two sets, and the mechanical grippers are arranged in two sets. One set of mechanical grippers, two columns of guide rails and one set of lead screw modules are matched and correspond to each other. The guide rails precisely restrict the bottom movement of the mechanical grippers, and the lead screw modules precisely restrict the upper part of the mechanical grippers to ensure the accuracy of battery pack disassembly and installation.

[0013] Compared with existing technologies, the advantages of this utility model include: the PLC control cabinet adopts an overhead design, which does not affect the reciprocating stroke of the lead screw module and plays a role in counterweight balance, ensuring balance during battery pack installation and removal. The installation and removal of the battery pack are safe and reliable. A forklift hole device is provided, allowing the forklift to block and position the battery pack. By adjusting the fork position, the installation and removal of the battery pack can be adjusted, ensuring accurate insertion and removal of the battery pack from the compartment. The staggered arrangement of the omnidirectional ball and guide wheel assemblies does not interfere with each other, ensuring smooth operation of the installation equipment and enabling the battery pack to be pulled out.

Detailed Implementation

[0019] In view of the shortcomings of the prior art, this invention, through long-term research and extensive practice, has yielded the technical solution of this utility model. The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments.

[0020] Please see Figure 1 , Figure 2 and Figure 3 , Figure 1 This is a three-dimensional structural view of a universal liquid-cooled battery pack installation device for the energy storage industry provided in this embodiment of the utility model; Figure 2 This is a top view of the structure of a universal liquid-cooled battery pack installation device for the energy storage industry provided in this embodiment of the utility model; Figure 3This is a structural front view of a universal liquid-cooled battery pack installation device for the energy storage industry provided in this embodiment of the utility model. The universal liquid-cooled battery pack installation device for the energy storage industry is characterized by comprising a PLC control cabinet 1, a battery pack support fixture 2, a drive device 4, mechanical grippers 5, limit sensors 6, heavy-duty feet 7, forklift hole devices 8, and guide rails 9. The PLC control cabinet 1 is located at one end of the battery pack support fixture 2. The drive device 4 consists of a lead screw module 401, a driver 402, a servo motor 403, and a drag chain 4013. The battery pack support fixture 2 consists of a guide wheel assembly 201, a universal ball joint 202, and a support base 203. The lead screw module 401 is assembled inside the upper part of the support base 203. The guide rail 9 is assembled inside the upper part of the support base 203. Balls 202 are assembled on both sides of the inner wall of the support base 203. The guide wheel assembly 201 is assembled on both outer walls of the support base 203. The mechanical gripper 5 is slidably assembled on the guide rail 9 and the lead screw module 401. Limit sensors 6 are assembled at both ends of the support base 203. The heavy-duty foot cup 7 is assembled at the bottom of the support base 203. The forklift hole device 8 is assembled at the bottom of the support base 203. The forklift hole device 8 consists of fork tooth fixing bolts 801 and fork tooth frame 802. The PLC control cabinet 1 is designed to be suspended. The suspended design can reduce the overall weight and play the role of counterweight to maintain balance. Moreover, it will not affect the reciprocating motion and retraction stroke of the lead screw module 401. The universal balls 202 and the guide wheel assembly 201 are staggered. The number of universal balls 202 is twice the number of guide wheel assemblies 201.The omnidirectional ball 202 and guide wheel assembly 201 are staggered and do not affect each other. The omnidirectional ball further limits the running trajectory of the battery pack on the battery pack installation fixture, and the guide wheel assembly limits the running trajectory of the battery pack into the storage position. The two work together to ensure the accuracy of battery pack installation and disassembly. The number of heavy-duty feet 8 is 6-8. To ensure the stability and safety of placement, the number of heavy-duty feet can be selected according to the length and width of the battery pack support fixture. The number of forklift hole devices 8 is 2. The fork tooth fixing bolts 801 are adjustment bolts. The fork tooth fixing bolts 801 are distributed at the bottom and one side of the fork tooth frame 802. According to the disassembly and installation position of the battery pack, the position of the forklift fork is adjusted by the fork tooth fixing bolts 801, thereby completing the position adjustment of the battery pack, and thus enabling the battery pack to be accurately assembled in the container storage position. In actual use, the position of the battery pack can be adjusted according to the battery pack installation and disassembly position. The battery pack is designed to match the forklift mounting holes in its installation direction, allowing for both forward and side mounting. To ensure precision in battery pack installation and removal, four rows of guide rails, two sets of lead screw modules, and two sets of mechanical grippers are used. One set of mechanical grippers, two rows of guide rails, and one set of lead screw modules are matched and correspond to each other. The guide rails precisely restrict the bottom movement of the mechanical grippers, while the lead screw modules precisely restrict the top movement of the mechanical grippers, ensuring precision in battery pack installation and removal. The two sets of mechanical grippers provide stable clamping of the battery pack.

[0021] In actual use, the battery pack is gripped by mechanical grippers, and the mechanical grippers are driven to move back and forth by a drive device, thereby pulling the battery pack and completing the function of pushing the battery pack into the compartment or taking the battery pack out of the compartment.

[0022] Example 1: A general liquid-cooled battery pack installation device for the energy storage industry, the difference being that the dimensions of the battery pack support fixture include, but are not limited to, a length of 1000-2400MM, a width of 500-1400MM, and a height of 150-500MM, and the corresponding battery pack support fixture is matched according to the actual size of the battery pack.
