If not thoroughly cleaned, this will seriously affect the accuracy of the next round of test data.

[0003] Currently, cleaning is mostly done manually by sweeping or vacuuming, which is not only inefficient but also makes it difficult to completely remove impurities adhering to the bottom and walls of the tank, especially at the corners and junctions, where cleaning dead spots are obvious. In addition, existing cleaning devices are mostly handheld or lack a stable support structure. After the device is placed inside the tank, operators must continuously lift the device to the corresponding height when cleaning at different heights. This is physically demanding, easily leads to fatigue and even operational errors, seriously affecting cleaning effectiveness and safety, and lacks a convenient height adjustment and positioning structure.

[0004] Therefore, there is an urgent need for a tank internal cleaning device with a stable structure, adjustable height, and cleaning synergy function to improve efficiency and reliability. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0027] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0028] like Figures 1-2As shown in the figure, the present invention provides a battery cell gas collection tank cleaning device, including a hollow main rod 1, a bearing cylinder 2 sleeved on the outer side of the hollow main rod 1, and a support block 5 connected to the surface of the bearing cylinder 2. An electromagnet block 8 is installed on the surface of the support block 5. The bearing cylinder 2 is slidably connected to the inner wall of the support block 5, and the outer shell of the bearing cylinder 2 is made of iron.

[0029] A positioning component is provided on the surface of the support block 5. The positioning component includes a plurality of first support cylinders 7, and the first support cylinders 7 are connected to the surface of the support block 5. A first adjusting rod 6 is slidably connected inside the first support cylinder 7, and a first external clamping spiral locking chuck 18 is provided on the surface of the first support cylinder 7 and the first adjusting rod 6. A positioning block 23 is provided at the end of the first adjusting rod 6 away from the first support cylinder 7.

[0030] A first cleaning component is provided at one end of the hollow main rod 1, and a second cleaning component is provided on the surface of the hollow main rod 1. The first cleaning component is used to clean the bottom wall of the tank, and the second cleaning component is used to clean the inner side wall of the tank.

[0031] In one embodiment of this utility model, to reliably install the entire cleaning device inside the battery cell gas collection tank, the positions of the first and second cleaning components are first adjusted according to the tank size so that they can fit against the bottom and side walls of the tank, respectively. After adjustment, the operator vertically places the entire cleaning device into the collection tank, positioning it in the cleaning position. Subsequently, by manually pulling the first adjusting rod 6 located inside the multiple first support cylinders 7, the multiple positioning blocks 23 at their distal ends extend outward until each positioning block 23 reliably abuts against the inner wall of the collection tank. At this time, the operator tightens the first external clamping spiral locking chuck 18 to lock the first adjusting rod 6 and the first support cylinder 7. The stable friction generated between the multiple positioning blocks 23 and the inner wall of the tank achieves rapid positioning and stable fixation of the cleaning device inside the tank, effectively solving the problem of inconvenient installation of cleaning equipment inside tanks of different sizes. It is highly adaptable and easy to operate.

[0032] In this invention, the hollow main rod 1 is rotatably connected to the bearing cylinder 2 via a rotating fit structure, allowing the hollow main rod 1 to rotate flexibly relative to the bearing cylinder 2 during operation. With this rotating structure, the operator can manually or power-drivenly rotate the hollow main rod 1, thereby achieving 360° uniform cleaning of the inner wall of the collection tank by the first and second cleaning components, greatly improving the cleaning effect and efficiency.

[0033] When cleaning areas at different heights are required, simply disconnect the power to the electromagnet block 8 to release the electromagnetic attraction, allowing the bearing cylinder 2 to slide smoothly within the support block 5. The operator can then push the hollow main rod 1 up and down, causing the bearing cylinder 2 to rise and fall as a whole, adjusting the height of the cleaning assembly. After adjustment, power is restored to the electromagnet block 8, which uses magnetic attraction to fix the iron bearing cylinder 2 within the support block 5, achieving rapid and stable height locking. This structure eliminates the need for complex mechanical limits or external fastening components, improving operational efficiency while reducing manual intervention, making the operation safer and more convenient.

[0034] The aforementioned structural design of this cleaning device not only solves the problems of difficult fixing of cleaning equipment, low positioning efficiency, and high manual burden in existing technologies, but also improves the accuracy and consistency of cleaning operations. Furthermore, the device can be reused in collection tanks of different models or sizes, demonstrating strong adaptability and high potential for widespread application. It shows promising application prospects in lithium battery thermal runaway testing platforms, power battery safety verification laboratories, and related testing institutions, helping to improve the cleanliness of the testing environment, shorten testing intervals, and effectively ensure the accuracy and reliability of subsequent test data.

[0035] In this embodiment, the surface of the positioning block 23 is provided with an anti-slip pad layer. The anti-slip pad layer can form a higher coefficient of friction between the positioning block 23 and the inner wall of the collection tank, thereby effectively enhancing the overall stability after the device completes radial support, avoiding slippage or displacement of the positioning block due to rotational torque, vibration or water pressure fluctuations during the cleaning process, and improving the fixed reliability of the entire device in the tank.

[0036] Anti-slip pads are typically made of flexible or elastic materials, adapting to minor bumps or unevenness on the inner wall of the tank, thus providing cushioning. This flexible fit further increases the contact area between the positioning block and the tank, thereby improving support stability and preventing scratches or abrasions to the tank wall caused by direct hard contact. This helps protect the tank structure and extend the equipment's service life.

[0037] In this embodiment, the first cleaning component includes a threaded sleeve 13, and the threaded sleeve 13 is internally threaded with a third adjusting rod 22. One end of the third adjusting rod 22 is movably connected to a first mounting panel 11, and the surface of the first mounting panel 11 is provided with a first cleaning element 12.

[0038] The threaded sleeve 13 serves as a fixed mounting base and has an internal threaded structure for threaded connection with the third adjusting rod 22. By rotating the third adjusting rod 22, fine adjustment in the axial direction can be achieved, thereby moving the first mounting panel 11 connected to its end along the radial or vertical direction of the hollow main rod 1, thus flexibly changing the contact position and cleaning range of the first cleaning component 12 at the bottom of the tank.

[0039] One end of the third adjusting rod 22 is movably connected to the first mounting panel 11, giving the first mounting panel 11 a certain degree of freedom to rotate or swing, adapting to local unevenness or structural changes at the bottom of the tank, and achieving a close-fitting cleaning. The surface of the first mounting panel 11 is provided with multiple first cleaning components 12, which can be in the form of brush bristles, scrapers, or soft cleaning materials, to facilitate the effective removal of contaminants such as dust, electrolyte, or debris remaining at the bottom of the tank.

[0040] The advantage of this structural design lies in its combination of high precision thread adjustment and flexible installation components. This not only improves the cleaning coverage and efficiency but also ensures the stability and ease of operation of the cleaning components. It is particularly suitable for cleaning the bottoms of different types of collection tanks, enhancing the versatility and practicality of the entire cleaning system.

[0041] In this embodiment, a damping shaft 10 is provided at one end of the third adjusting rod 22, and the first mounting panel 11 is mounted on the outside of the damping shaft 10. The key to this structural design is that the introduction of the damping shaft 10 enables the first mounting panel 11 to have a certain rotational buffering capacity during the rotation of the hollow main rod 1. Specifically, the damping shaft 10 can provide controlled rotational resistance between the first mounting panel 11 and the third adjusting rod 22, thereby preventing the first cleaning component 12 from swinging violently or colliding due to inertia during rotation, ensuring that it maintains a stable and uniform contact state when cleaning close to the bottom of the tank, and significantly improving cleaning efficiency and cleaning effect.

[0042] Meanwhile, the damping structure can also absorb the vibration and instantaneous load caused by the impact of water flow or airflow during rotation, reducing wear between components and extending the service life of the entire cleaning assembly. In addition, the damping characteristics allow the first mounting panel 11 to automatically and slowly adjust its angle and conform to the surface when it encounters local protrusions, deposits, or deformed areas on the bottom of the tank, further enhancing the fit and safety of the cleaning process and preventing damage to the tank or device from hard impacts.

[0043] In summary, the damping shaft 10 not only optimizes the smoothness and gentleness of the cleaning action, but also improves the operational reliability of the device in complex environments. It is one of the key technical points in the structure of this utility model that enhances cleaning quality and protection.

[0044] In this embodiment, the second cleaning component includes a plurality of second support cylinders 14, and the second support cylinders 14 are disposed on the surface of the hollow main rod 1. The second adjustment rod 9 is slidably connected inside the second support cylinder 14, and a second mounting panel 16 is provided at one end of the second adjustment rod 9. A second cleaning component 17 is mounted on the surface of the second mounting panel 16. A second external clamping spiral locking chuck 15 is provided on the surfaces of the second adjustment rod 9 and the second support cylinder 14.

[0045] The second support cylinder 14 is fixedly installed on the outer surface of the hollow main rod 1 and serves as a support and guide mechanism. A second adjusting rod 9 is slidably connected inside the cylinder. Through the reciprocating adjustment of the second adjusting rod 9, the second mounting panel 16 can be freely extended and retracted radially, thereby adjusting the contact distance between the second cleaning component 17 and the tank wall. This structure facilitates flexible adaptation to collection tanks of different sizes or shapes, improving the versatility and cleaning coverage of the device.

[0046] The second mounting panel 16 is located at the end of the second adjusting rod 9 and serves as a platform for supporting the cleaning elements. Several second cleaning components 17 are evenly distributed on its surface. These cleaning components can take the form of brush bristles, flexible scrapers, or cleaning pads, which can effectively remove carbon powder, electrolyte residue, or other solid-liquid mixed contaminants adhering to the inner wall surface of the tank, achieving comprehensive decontamination.

[0047] To ensure that the second adjusting rod 9 remains stable and does not slip after adjustment, a second external clamping spiral locking chuck 15 is provided on both the second support cylinder 14 and the exterior of the second adjusting rod 9. This locking chuck adopts a clamping and tightening structure, which is convenient for manual operation and can quickly lock the adjusting rod axially, preventing positional displacement caused by vibration or water pressure during cleaning, and improving the accuracy and consistency of the cleaning action.

[0048] In this embodiment, a rotating handle 3 is provided on the surface of the hollow main rod 1. The rotating handle 3 is fixedly installed on the outside of the hollow main rod 1. When using the device, the operator can directly hold and rotate the rotating handle 3 manually, thereby driving the hollow main rod 1 to rotate freely within the bearing cylinder 2. Since a first cleaning component is provided at one end of the hollow main rod 1, and several second cleaning components are distributed around its outer periphery, this rotation action can simultaneously drive the cleaning brush to rotate around the center of the tank, realizing dynamic cleaning of the bottom and side walls of the collection tank.

[0049] like Figures 1-4 As shown, in one embodiment of the present invention, a multi-connected hose 4 is provided inside the hollow main rod 1, a water injection hole 20 is provided on one side of the second mounting panel 16, and a plurality of side water injection holes 19 are provided on the other side. The side water injection holes 19 and the second cleaning component 17 are alternately distributed on the side surface of the second mounting panel 16, and the water outlet end of the multi-connected hose 4 is provided inside the water injection hole 20.

[0050] In this embodiment, to further improve cleaning efficiency and decontamination ability, a multi-port hose 4 is installed inside the hollow main rod 1 to provide water to the cleaning components. The multi-port hose 4 can be connected to an external high-pressure water source to accurately deliver cleaning water to the second cleaning component, forming a linked water spray cleaning system.

[0051] Specifically, a water injection hole 20 is provided on one side of the second mounting panel 16. The outlet end of the multi-way hose 4 is connected inside the water injection hole 20 to achieve a closed connection of the water supply path, thereby effectively controlling the water flow direction and preventing leakage or spray deviation. In conjunction with this, multiple side water jet holes 19 are evenly distributed on the other side of the second mounting panel 16, and are arranged alternately with the second cleaning component 17. This structural arrangement ensures that while the cleaning component 17 cleans the inner wall surface of the tank, the side water jet holes 19 can simultaneously spray water onto the target area, thus forming a synergistic effect of "brushing + rinsing".

[0052] This design significantly enhances cleaning effectiveness, not only breaking down particles, dried electrolyte residue, or oil stains adhering to the tank walls, but also rapidly flushing contaminants off the surface during the rotating cleaning process, avoiding repeated dragging and secondary contamination. It exhibits a clear advantage in removing contaminants, especially from the inner walls of the tank containing sticky impurities or significant amounts of residual liquid or powder.

[0053] Meanwhile, the structure effectively reduces the complexity of external piping by using a built-in water supply channel instead of external pipe routing, avoids unstable factors such as hose tangling and detachment, improves structural compactness and operational safety, and facilitates daily maintenance and cleaning.

[0054] In summary, this embodiment combines the multi-channel hose 4, the water flow guiding structure, and the cleaning components to construct a highly efficient, stable, and structurally sound sidewall flushing system. This not only improves the overall cleaning performance but also expands the adaptability and practical value of this invention in complex working environments.

[0055] In this embodiment, to achieve a more comprehensive cleaning effect inside the collection tank, several bottom water jet holes 21 are provided on the lower surface of the second mounting panel 16. This structure further expands the spray direction and coverage area based on the original side water jet function, enhancing the cleaning ability of the area where the inner wall of the tank meets the bottom edge.

[0056] The bottom water jet holes 21 are arranged facing downwards from the mounting panel. When high-pressure water flows into the second mounting panel 16 through the multi-way hose 4, it can be sprayed out simultaneously from the side water jet holes 19 and the bottom water jet holes 21. The bottom water jet holes 21 are mainly used to spray water into the area below, which can effectively flush out stubborn contaminants at the junction of the tank side wall and bottom wall, corners, or sediment grooves, and fill in cleaning blind spots that traditional brush bristles cannot reach.

[0057] This staggered perforation design, with its omnidirectional water spray, enables the second cleaning component to achieve a synergistic cleaning effect of "surrounding + downward flushing." During the device's rotation and movement, it forms a continuous and uniform covering water curtain, significantly improving the speed of dirt removal and rinsing efficiency. It is particularly suitable for scenarios involving collection tanks containing carbon powder, adhesive, or viscous electrolyte residues after battery cell thermal runaway testing.

[0058] In addition, the addition of the bottom water jet hole 21 makes the spray system more compact and centralized in structure, eliminating the need for additional nozzles or water pipe paths, reducing the overall complexity of the equipment, and avoiding the increased wear and failure risks of exposed components.

[0059] In summary, the design of the bottom water jet holes 21 not only improves the comprehensiveness and uniformity of cleaning coverage, but also effectively solves the problems of difficulty in reaching the bottom edge and the presence of cleaning dead corners in traditional tank cleaning. It is an important technical aspect for achieving efficient and all-round cleaning.

[0060] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
