When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0016] The present invention provides the following embodiments Embodiment 1 The embodiment of the present invention provides a detection device for energy storage batteries, asFigures 1-6 As shown in the figure, it includes: a detection cabinet 1, weight detection components 2 are provided at the four corners of the bottom of the detection cabinet 1, a detection port 11 is provided on the detection cabinet 1, an appearance detection component 4 is provided at the detection port 11, and the appearance detection component follows the surface of the energy storage battery to undulate and roll through a roller 45. The roller 45 drives the displacement of a detection plate 43 and converts the displacement into an electrical signal. A connection component 6 is provided in the detection port 11, and a fire prevention component 8 is provided on the side of the detection cabinet.

[0017] The working principle and beneficial effects of the above technical solution are as follows: When the detection cabinet 1 detects the energy storage battery, it is inserted into the detection port 11. The weight detection components 2 at the four corners of the bottom of the detection cabinet 1 adopt pressure sensor technology to convert the weight of an object into an electrical signal, and evaluate the state of the battery by detecting the weight change of the energy storage battery. The appearance detection component 4 at the detection port 11 follows the surface of the energy storage battery to undulate and roll through the roller 45, drives the displacement of the detection plate 43 and converts the displacement into an electrical signal, establishes a volume model of the energy storage battery based on the electrical signal to judge the relative change in the volume of the energy storage battery, and captures images of the surface of the energy storage battery to be detected. These images are converted into digital signals and analyzed by an image processing system to identify the appearance defects of the object. After the energy storage battery is inserted into the detection port 11, through the linkage of the mechanical structure, the connection component 6 extends and is electrically connected to the energy storage battery. When a fire occurs in the detection cabinet 1, the fire prevention component 8 can quickly respond and extinguish the fire by spraying carbon dioxide gas on the energy storage battery, controlling the spread of the fire and protecting the detection cabinet 1 from the threat of fire; In the present invention, the weight detection component 2 judges the state of the energy storage battery according to the change in the weight of the energy storage battery. This design can preliminarily judge the power situation inside the energy storage battery before conducting a power-on test on the energy storage battery. The appearance detection component 4 can not only convert the displacement generated by the volume expansion of the energy storage battery into an electrical signal, but also analyze the surface data of the energy storage battery. This design can timely understand the quality and safety of the energy storage battery. The connection component 6 can automatically match whether an energy storage battery is inserted into the detection port 11 through the linkage of the mechanical structure, ensuring the electrical safety of the detection cabinet 1. The design of the fire prevention component 8 can quickly respond when a fire occurs in the detection cabinet 1, extinguish the fire by spraying carbon dioxide gas, effectively control the spread of the fire, protect the detection cabinet 1 and the energy storage battery from the threat of fire, and improve the overall safety. The combination of the weight detection component 2 and the appearance detection component 4 can comprehensively detect the weight, volume change and appearance defects of the energy storage battery, ensure that the state and safety of the battery are fully evaluated, and improve the accuracy and reliability of the detection.

[0018] Embodiment 2 On the basis of Embodiment 1, the weight detection component 2 includes a weighing base 21. A weighing base hole 22 is provided on the weighing base 21. A hydraulic strut 23 is provided in the weighing base hole 22. The top of the hydraulic strut 23 is nested in the weighing top hole 24. The weighing top hole 24 is provided in the weighing top seat 25. A balance card 26 is fixedly connected to the bottom of the weighing top seat 25. The balance card 26 is sleeved on the weighing base 21. Limit columns 27 are symmetrically sleeved on both sides of the balance card 26. The limit columns 27 are threadedly connected to the weighing base 21. Tensile rods 28 are bolted to the front and back sides of the weighing base 21 and the balance card 26. An adjusting structure 3 is provided on the weighing top seat 25.

[0019] The adjusting structure 3 includes an adjusting knob 31. The adjusting knob 31 is rotatably connected to the weighing top seat 25. An ascending screw column 32 is bolted to the top of the adjusting knob 31. The ascending screw column 32 is fixedly connected to the detection cabinet 1.

[0020] The working principle and beneficial effects of the above technical solution are as follows: Before the energy storage battery is inserted into the detection cabinet 1, the hydraulic strut 23 is in a compressed state. The hydraulic strut 23 undergoes a certain amount of compressive deformation according to the weight of the detection cabinet 1. The weighing top seat 25 is stably sleeved on the weighing base 21 through the balance card 26 and the limit columns 27. The tensile rods 28 further enhance the structural stability and prevent unnecessary displacement during the measurement process. Since the amount of compressive deformation of the hydraulic strut 23 is proportional to the pressure it receives (i.e., the weight of the item), after the energy storage battery is inserted into the detection cabinet 1, the weight above the weighing top seat 25 changes. The sensor on the hydraulic strut 23 will convert the pressure change into an electrical signal for output. The adjusting structure 3 is mainly used to adjust the height of the four corners of the detection cabinet 1 to ensure that the detection cabinet 1 can remain level. By rotating the adjusting knob 31, the ascending screw column 32 can be screwed into or out of the adjusting knob, realizing the lifting and lowering of the positions of the four corners of the detection cabinet 1, thereby adjusting the level of the detection cabinet 1. In the present invention, the weight detection component 2 uses the hydraulic strut 23 as a weighing element, which has high precision and stability, can accurately measure the weight of the items placed in the detection cabinet 1. Moreover, the combined use of the balance card 26, the limit columns 27 and the tensile rods 28 enhances the overall stability of the weight detection component 2, ensuring the accuracy and safety of the measurement process. The design of the adjusting structure 3 enables the height of the four corners of the detection cabinet 1 to be flexibly adjusted. By rotating the adjusting knob 31 to drive the ascending screw column 32 to be screwed into or out, the lifting and lowering of the positions of the four corners of the detection cabinet 1 can be realized, thereby ensuring that the detection cabinet 1 always remains in a horizontal state and avoiding measurement errors caused by uneven ground.

[0021] Embodiment 3 On the basis of Embodiment 1, the appearance detection component 4 includes four groups of sliding grooves 41, the four groups of sliding grooves 41 are bolted to the detection cabinet 1, the four groups of sliding grooves 41 are respectively arranged around the detection port 11, cover plates 42 are bolted to the four groups of sliding grooves 41, detection plates 43 are slidably connected in the four groups of sliding grooves 41, a first compression elastic member 44 is provided between the detection plate 43 and the sliding groove 41, a roller 45 is rotatably connected to one end of the detection plate 43 close to the detection port 11, a coil 46 is sleeved on the other end of the detection plate 43, two ends of the coil 46 are connected to a detector, and permanent magnets 47 are nested and installed on the side walls of the four groups of sliding grooves 41 and the cover plates 42, and a video observation structure 5 is provided on one side of the detection port 11 close to the roller 45.

[0022] The video observation structure 5 includes four groups of light source lamps 51, the four groups of light source lamps 51 are respectively arranged on the inner walls around the detection port 11, and a micro scanning camera 52 is provided on one side of each of the four groups of light source lamps 51.

[0023] The working principle and beneficial effects of the above technical solution are as follows: The energy storage battery is inserted into the detection cabinet 1 from the detection port 11, the surface of the energy storage battery contacts the roller 45, the roller 45 rolls along with the undulation of the battery surface, the rolling of the roller 45 drives the detection plate 43 to slide in the sliding groove 41, and the first compression elastic member 44 generates elastic deformation when the detection plate 43 slides, so that the detection plate 43 can adapt to the undulation of the battery surface. A coil 46 is sleeved on the other end of the detection plate 43. The coil 46 cuts the magnetic field of the permanent magnet 47 during the sliding process to generate an induced current. The magnitude of the induced current is proportional to the displacement of the detection plate 43. The displacement signal is converted into an electrical signal by the detector, so as to judge the volume change of the energy storage battery. The design of the four groups of sliding grooves 41 and the cover plates 42 ensures the stable sliding of the detection plate 43. At the same time, when the energy storage battery is inserted into the detection port 11, the four groups of light source lamps 51 provide uniform illumination for the micro scanning camera 52, ensuring that the micro scanning camera 52 can clearly capture the image of the surface of the energy storage battery. The micro scanning camera 52 scans the surface of the battery, converts the captured image into a digital signal, and analyzes it through an image processing system to identify the appearance defects on the surface of the battery. Through the electrical signal generated by the coil 46 and the image data captured by the micro scanning camera 52, the system can comprehensively judge the volume change and appearance state of the energy storage battery and feedback the detection result in real time; Through the combination of the roller 45, the detection plate 43, the coil 46 and the permanent magnet 47, the present invention can convert the undulations on the surface of the battery into electrical signals, achieving high-precision volume change detection. At the same time, the combination of the micro scanning camera 52 and the light source lamp 51 can clearly capture the details on the surface of the battery, improving the accuracy of appearance defect detection. Moreover, the design of the coil 46 and the permanent magnet 47 realizes non-contact displacement detection, avoiding mechanical wear, extending the service life of the equipment, and improving the stability and reliability of detection. The sliding of the detection plate 43 and the rolling of the roller 45 are completely driven by the undulations on the surface of the battery, without external power, realizing an automated detection process, reducing manual intervention, and improving the detection efficiency.

[0024] Embodiment 4 On the basis of Embodiment 1, the connection component 6 includes a connection plug 61 which is slidably connected in the telescopic hole 62. The telescopic hole 62 is provided on the inner wall of the detection port 11. The input end of the connection plug 61 is connected to the electrical detection structure, and linkage structures 7 are provided on both sides of the connection plug 61.

[0025] The linkage structure 7 includes linkage grooves 71 which are provided on the left and right side walls of the detection port 11. Linkage pressure rods 72 are rotatably connected in the linkage grooves 71. The other ends of the linkage pressure rods 72 are hinged to pull rods 73. The bottom of the pull rod 73 is hinged to a bearing plate 74. A second compression elastic member 75 is provided between the bearing plate 74 and the cabinet body of the detection cabinet 1, and the bearing plate 74 is fixedly connected to the connection plug 61.

[0026] The working principle and beneficial effects of the above technical solution are as follows: When the energy storage battery is inserted into the detection port 11, the side surface of the energy storage battery contacts the linkage pressure rod 72 and applies an outward pressure. The linkage pressure rod 72 rotates outward, thereby driving the pull rod 73 to lift upward. The bearing plate 74 moves toward the energy storage battery under the pull of the pull rod 73, and the second compression elastic member 75 undergoes elastic deformation. The movement of the bearing plate 74 toward the energy storage battery drives the connection plug 61 to extend out of the telescopic hole 62 and slide toward the center of the detection port 11 to dock with the interface of the energy storage battery, realizing electrical connection. After the connection plug 61 is docked with the energy storage battery, the electrical detection structure detects the electrical performance of the energy storage battery through the connection plug 61. After the detection is completed, the energy storage battery is taken out from the detection port 11, and the second compression elastic member 75 returns to its original state, driving the bearing plate 74 and the connection plug 61 to reset, and the connection plug 61 retracts into the telescopic hole 62. Through the design of the linkage structure 7, the connection plug 61 can automatically dock with the energy storage battery without manual intervention, simplifying the operation process and improving the detection efficiency. The combined design of the linkage lever 72, the pull rod 73 and the bearing plate 74 ensures the stable sliding of the connection plug 61. At the same time, the design of the compression elastic member II 75 ensures the self-resetting property of the structure. When the energy storage battery is not inserted, the connection plug 61 retracts into the telescopic hole 62, avoiding the exposure of the plug to the external environment, preventing damage to the plug caused by dust, moisture, etc., and avoiding potential safety hazards (such as short circuits, electric shocks, etc.) that may be caused by the exposure of the plug to the external environment, improving the safety of the device and extending the service life of the connection plug 61.

[0027] Embodiment 5 On the basis of Embodiment 1, the fire prevention component 8 includes a fire sprinkler 81, which is nested and installed on the detection cabinet 1 in the detection port 11. A fire detection system is provided on the fire sprinkler 81. The fire sprinkler 81 is connected to a delivery pipe 82, and the delivery pipe 82 is built into the detection cabinet 1. The input end of the delivery pipe 82 is connected to a rotary joint 83, and the rotary joint 83 is fixedly connected to the side of the detection cabinet 1. A fixing bracket 84 is provided below the rotary joint 83, and the fixing bracket 84 is bolted to the detection cabinet 1. A carbon dioxide fire extinguisher 85 is provided inside the fixing bracket 84, and the output end of the carbon dioxide fire extinguisher 85 is connected to the rotary joint 83 through a connecting hose 86.

[0028] The working principle and beneficial effects of the above technical solution are as follows: When a fire occurs in the detection cabinet 1, the fire detection system will trigger an alarm and activate the fire prevention component 8. The carbon dioxide fire extinguisher 85 is connected to the rotary joint 83 through the connecting hose 86. The rotary joint 83 delivers carbon dioxide gas to the delivery pipe 82, and the delivery pipe 82 delivers the carbon dioxide gas to the fire sprinkler 81. The fire sprinkler 81 sprays carbon dioxide gas into the energy storage battery in the detection port 11. The carbon dioxide gas is evenly sprayed into the fire area through the fire sprinkler 81, rapidly reducing the oxygen concentration and suppressing the flame combustion. After the fire extinguishing is completed, the carbon dioxide fire extinguisher 85 can be replaced or refilled. The design of the rotary joint 83 and the connecting hose 86 facilitates disassembly and maintenance; The fire prevention component 8 can be quickly activated during a fire. It sprays carbon dioxide gas into the fire area through the fire sprinkler 81 to achieve rapid fire extinguishing and effectively control the spread of the fire. The carbon dioxide gas can quickly reduce the oxygen concentration in the fire area and inhibit the flame combustion. At the same time, it will not cause secondary damage to the detection cabinet 1 and the energy storage battery. The fire extinguishing effect is remarkable. Moreover, the fire prevention component 8 is integrated inside the detection cabinet 1. The designs of the fire sprinkler 81, the delivery pipe 82, the rotary joint 83 and the carbon dioxide fire extinguisher 85 are compact, saving space and not affecting other functions of the detection cabinet. The designs of the rotary joint 83 and the connecting hose 86 make the carbon dioxide fire extinguisher 85 easy to disassemble, replace or refill, reducing the maintenance cost and time.
