[0023] Now, in combination with the attached drawings and preferred embodiments, the present utility model will be further described in detail. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.
[0024] Referring to Figure 1 - Figure 4 As shown, the present utility model provides a technical solution: a cell quality detection device based on thermogravimetric analysis technology, including a thermogravimetric analyzer 1. The bottom end of the thermogravimetric analyzer 1 is fixedly connected with a support base 2. The top end of the thermogravimetric analyzer 1 is equipped with a display board 3. The top end of the display board 3 is fixedly connected with a base 4 by bolts. The top end of the base 4 is fixedly connected with a placing board 5 by bolts. The top end of the placing board 5 is provided with a sealing cover 6. The inner cavity of the placing board 5 is equipped with a detection cylinder 7. The inner cavity of the detection cylinder 7 is rotationally connected with a rotating rod 8. The surface of the rotating rod 8 is fixedly connected with a ring 9. Both sides of the ring 9 are fixedly connected with L-shaped columns 10. The inner cavity of the L-shaped column 10 is slidably connected with a sliding column 11. The bottom end of the sliding column 11 is fixedly connected with a scraper 12. When the staff needs to clean the bottom end of the inner cavity of the detection cylinder 7, the staff rotates the rotating rod 8, so that the bottom end of the rotating rod 8 rotates through the rotating column 16, and the rotating rod 8 drives the ring 9 and the L-shaped columns 10 to rotate. The sliding column 11 and the first spring 13 are continuously pushed downward by the rebounding force of the first spring 13, so that the surface of the first spring 13 fits more closely to the bottom end of the detection cylinder 7. As the rotating rod 8 rotates, the rotating rod 8 drives the surface of the scraper 12 to clean the bottom end of the inner cavity of the detection cylinder 7. At this time, the staff pulls the rotating rod 8 upward to drive the detection cylinder 7 to move upward, and at the same time drives the surface of the orientation rod 18 to slide in the inner cavity of the orientation groove 17, so that the detection cylinder 7 is separated from the inner cavity of the placing board 5, and the residues are uniformly processed. Through the setting of the above structure, it is convenient for the staff to clean the dirt at the bottom end of the inner cavity of the detection cylinder 7, prevent some residues from adsorbing inside the detection cylinder 7 when the cell is subjected to thermogravimetric treatment, and thus affect the accuracy of subsequent detection.
[0025] Referring to Figure 4As shown in the figure, in this embodiment: a first spring 13 is fixedly connected to the inner cavity of the L-shaped column 10, and the bottom end of the first spring 13 is fixedly connected to the sliding column 11. Through the arrangement of the first spring 13, the rebounding force of the first spring 13 continuously pushes the sliding column 11 to displace downward, and at the same time, the bottom end of the scraper 12 fits more closely to the inner cavity of the detection cylinder 7, thereby improving the cleaning effect.
[0026] Referring to Figure 4 As shown in the figure, in this embodiment: a guiding groove 14 is formed inside the L-shaped column 10, a guiding rod 15 is slidably connected to the inner cavity of the guiding groove 14, and one end of the guiding rod 15 close to the sliding column 11 is fixedly connected to the sliding column 11. Through the rebounding force of the first spring 13 continuously pushing the sliding column 11 to displace downward, the surface of the guiding rod 15 is driven to slide in the inner cavity of the guiding groove 14 at the same time. Through the arrangement of the above structure, the sliding column 11 maintains a directional displacement when displacing.
[0027] Referring to Figure 4 As shown in the figure, in this embodiment: a rotating column 16 is rotatably connected to the inner cavity of the detection cylinder 7, and the surface of the rotating column 16 contacts the bottom end of the rotating rod 8. Through the arrangement of the rotating column 16, when the rotating rod 8 rotates, the rotating rod 8 rotates uniformly with the sealing cover 6, further improving the smooth effect of the rotating rod 8.
[0028] Referring to Figure 3 As shown in the figure, in this embodiment: a directional groove 17 is formed inside the placement plate 5, a directional rod 18 is slidably connected to the inner cavity of the directional groove 17, and one end of the directional rod 18 close to the detection cylinder 7 is fixedly connected to the detection cylinder 7. When the staff pulls the rotating rod 8, the detection cylinder 7 is driven to gradually disengage from the inner cavity of the placement plate 5, and at the same time, the detection cylinder 7 drives the surface of the directional rod 18 to slide in the inner cavity of the directional groove 17. Through the arrangement of the above structure, the detection cylinder 7 maintains a directional displacement when disengaging from the placement plate 5.
[0029] Referring to Figure 5 and Figure 6 As shown in the figure, in this embodiment: a heat conduction tube 19 is fixedly connected to the surface of the placement plate 5, a sealing rod 20 is slidably connected to the inner cavity of the heat conduction tube 19, a gasket 21 is installed on the surface of the sealing rod 20, and a fixing bolt 22 is threadedly connected to the inner cavity of the sealing rod 20. When the staff needs to dissipate heat from the detection device, the staff rotates the fixing bolt 22, so that the fixing bolt 22 gradually disengages from the inner cavity of the sealing rod 20 through threaded connection. Subsequently, the staff pulls the sealing rod 20 outward, so that the sealing rod 20 drives the gasket 21 and the sealing block 25 to displace. As the sealing rod 20 displaces, the sealing rod 20 drives the surface of the square rod 24 to slide in the inner cavity of the square rod 24. Through the arrangement of the above structure, it is convenient for the staff to open the heat conduction tube 19 and facilitate the subsequent heat dissipation treatment of the detection device.
[0030] Referring to Figure 5 andFigure 6 As shown in the figure, in this embodiment: a chute 23 is provided inside the heat conduction tube 19, and a square rod 24 is slidably connected to the inner cavity of the chute 23. One end of the square rod 24 close to the sealing rod 20 is fixedly connected to the sealing rod 20. When the staff pulls the sealing rod 20, it drives the surface of the square rod 24 to slide in the inner cavity of the chute 23. Through the setting of the above structure, the sealing rod 20 maintains a directional displacement during displacement, preventing the sealing rod 20 from shifting and affecting the sealing effect.
[0031] Refer to Figure 5 and Figure 6 As shown in the figure, in this embodiment: one end of the sealing rod 20 is fixedly connected with a sealing block 25, and the surface of the sealing block 25 fits with the inner cavity of the heat conduction tube 19. Through the setting of the sealing block 25, the surface of the sealing block 25 can effectively fit and seal with the inner cavity of the heat conduction tube 19, further improving the sealing effect.
[0032] Working principle: When the staff needs to clean the bottom end of the inner cavity of the detection cylinder 7, the staff rotates the rotating rod 8, so that the bottom end of the rotating rod 8 rotates through the rotating column 16, and the rotating rod 8 drives the circular ring 9 and the L-shaped column 10 to rotate. The rebound force of the first spring 13 continuously pushes the sliding column 11 and the first spring 13 downward, making the surface of the first spring 13 fit more closely to the bottom end of the detection cylinder 7. As the rotating rod 8 rotates, the rotating rod 8 drives the surface of the scraper 12 to clean the bottom end of the inner cavity of the detection cylinder 7. At this time, the staff pulls the rotating rod 8 upward to drive the detection cylinder 7 to move upward, and at the same time drives the surface of the guiding rod 18 to slide in the inner cavity of the guiding groove 17, so that the detection cylinder 7 is separated from the inner cavity of the placing plate 5, and the residues are uniformly processed. Through the setting of the above structure, it is convenient for the staff to clean the dirt at the bottom end of the inner cavity of the detection cylinder 7, preventing some residues from adsorbing inside the detection cylinder 7 during the thermogravimetric treatment of the battery cell, thereby affecting the accuracy of subsequent detection. When the staff needs to dissipate heat from the detection device, the staff rotates the fixing bolt 22, so that the fixing bolt 22 gradually disengages from the inner cavity of the sealing rod 20 through threaded connection. Then the staff pulls the sealing rod 20 outward, so that the sealing rod 20 drives the gasket 21 and the sealing block 25 to displace. As the sealing rod 20 displaces, the sealing rod 20 drives the surface of the square rod 24 to slide in the inner cavity of the square rod 24. Through the setting of the above structure, it is convenient for the staff to open the heat conduction tube 19, facilitating the subsequent heat dissipation treatment of the detection device.
