[0002] As the core component of fuel cells, bipolar plates need to maintain a very high degree of cleanliness. The dyne pen must reach No. 42 or above to ensure the quality of the plate coating. The quality of the coating directly affects the conductivity and durability of the bipolar plates, and thus affects the quality of fuel cell products.

[0003] At present, the cleaning process of bipolar plates mostly involves multiple cleanings using cleaning agents such as hydrocarbons, and most of them are manual operations. In order to maintain the cleanliness of the bipolar plates, they are usually cleaned repeatedly multiple times in order to achieve the required cleanliness level.

[0004] However, first of all, manual cleaning is labor-intensive, which will increase a lot of additional labor costs and is inefficient.

This not only makes the operation cumbersome, but also due to manual operation, the flushing force of the detergent is limited, resulting in a very limited cleaning effect.

[0033] Reference Figure 4 As shown, due to the existence of a horizontal channel inside the bipolar plate 4, the device can conveniently tilt the bipolar plate 4 through the arrangement of the first card block 102, the second card block 103 and the third card block 104, so that the horizontal channel inside the bipolar plate 4 is tilted, which is not only conducive to the detergent entering the interior of the bipolar plate 4 to clean the horizontal channel during the up and down movement of the device, but also conducive to the smooth discharge of the detergent placed in the horizontal channel inside the bipolar plate 4 after cleaning, which is conducive to the subsequent drying operation, facilitates the rapid use of the bipolar plate, and greatly improves the cleaning efficiency of the bipolar plate.

The rotating shaft 204 is rotatably connected to the arc gear block 205, and the top of the arc gear block 205 is fixedly connected to a transmission frame. A through-hole 301 is inserted into a through-hole 5, and a plurality of side openings 501 are opened on the through-hole 5. An inner column 502 is provided inside the through-hole 5, and one end of the inner column 502 close to the L-shaped limit plate 3 is fixedly connected to a rotating block 504, and one end of the inner column 502 close to the transmission column 207 is fixedly connected to a clamping block 503, and a clamping mechanism is provided on the inner column 502 for clamping each bipolar plate 4 inserted into the bayonet 105.

[0036] By setting up and cooperating with the self-locking mechanism and the oscillation mechanism, the clamping mechanism set on the inner column 502 and the self-locking of the rotating block 504 screwed into the L-shaped limit plate 3 are utilized, which not only successfully realizes the successful locking of the bipolar plate 4 in the bayonet 105, but also successfully realizes the left and right swinging of the bipolar plate 4 during the cleaning process, thereby greatly improving the cleaning efficiency of the device. The structure is sophisticated and efficient, and has great application prospects.

[0037] Among them, it should be supplemented that the control shaft 203 slides up and down against the inner wall of the transmission frame, the arc tooth block 205 is engaged with the bottom tooth block 208, the inner column 502 can pass through the second card block 103 or the third card block 104, and the end of the inner column 502 close to the card block 503 can be rotated to engage with the card interface 209, and the four corner edges of the bipolar plate 4 are provided with fixing holes 401, and the through column 5 can pass through the fixing hole 401, and the triangular parts of the bipolar plate 4 are respectively placed on the first card block 102 , in the bayonet slots 105 opened on the second clamping block 103 and the third clamping block 104, the distance between the two limiting protrusions 602 in the side opening 501 is greater than the thickness of the bipolar plate 4, and the distance between the two limiting protrusions 602 in the side opening 501 is less than the length of the side opening 501. When the rotating block 504 is placed in the L-shaped limiting plate 3, the limiting protrusion 602 extends from the side opening 501, and the clamping block 503 is screwed into the clamping interface 209 so that the inner column 502 is connected to the transmission column 207.

[0038] Example 2

[0039] The clamping mechanism includes a plurality of spring recesses 6 provided on the inner column 502, the inner bottom surface of the spring recess 6 being fixedly connected to a spring 601, and one end of the spring 601 away from the inner bottom surface of the spring recess 6 being fixedly connected to a limiting protrusion 602, which can pass through the side opening 501. The number of spring recesses 6 is twice the number of side openings 501, and each side opening 501 corresponds to two spring recesses 6. Through such an arrangement, the bipolar plate 4 placed in the bayonet 105 can be clamped, so that the bipolar plate 4 swings left and right in the bayonet 105 following the left and right movement of the inner column 502, thereby improving the cleaning efficiency of the bipolar plate 4.

[0040] The functional principle of the present invention can be explained through the following operation mode:

[0041] When using the device, first insert the bipolar plate 4 into the slots 105 provided on the first card block 102, the second card block 103 and the third card block 104, and then Figure 5As shown, one end of the bipolar plate 4 is placed in the first card block 102 and the third card block 104 respectively, and the lower side of the other end of the bipolar plate 4 is placed in the second card block 103. At this time, the fixing holes 401 opened on the bipolar plate 4 are aligned with the corresponding through-holes 301 respectively. The user then inserts the through-hole 301 into the second card block 103 and the third card block 104. During this process, the through-hole 5 will pass through the fixing hole 401 to limit the bipolar plate 4 in the bayonet 105. At this time, the side opening 501 opened on the through-hole 5 will be placed in the bayonet 105. The user then inserts the inner column 502 into the interior of the through-hole 5. It should be noted that during insertion, the limiting protrusion 602 provided on the inner column 502 needs to avoid the side opening 501 opened on the through-hole 5. When the inner column 502 passes through the through-hole 5, When the side wall of the second clamping block 103 or the third clamping block 104 is docked with the transmission column 207, the clamping block 503 is inserted into the transmission column 207, and then the rotating block 504 is pulled into the L-shaped limit plate 3. At the same time, the clamping mechanism will extend out of the interior of the through column 5 through the side opening 501, and the clamping block 503 rotates so that the inner column 502 is clamped with the transmission column 207. It should be noted that the spring 601 in the clamping mechanism is in a compressed state when the limiting protrusion 602 does not extend out of the through column 5 through the side opening 501, and the limiting protrusion 602 slides against the inner wall of the through column 5. When the clamping mechanism extends out of the through column 5 through the side opening 501, two limiting protrusions 602 in a group of clamping mechanisms will be placed on both sides of a bipolar plate 4.

[0042] After the above operations are completed, the waterproof motor 2 can be started. The rotation of the output end of the waterproof motor 2 will drive the turntable 202 to start rotating, and the control shaft 203 will rotate with the turntable 202. Through the setting of the transmission frame and the arc tooth block 205, the arc tooth block 205 will swing left and right on the rotating shaft 204. Since the arc tooth block 205 and the bottom tooth block 208 are engaged with each other, the transmission column 207 will slide left and right in the limiting ring block 206, and the inner column 502 will slide left and right in the through column 5, thereby driving the bipolar plate 4 to swing left and right in the bayonet 105. Not only is the bipolar plate 4 successfully locked in the bayonet 105, but the bipolar plate 4 is also successfully swung left and right during the cleaning process, thereby greatly improving the cleaning efficiency of the device. The structure is sophisticated and efficient, and has great application prospects.

[0043] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
