[0030] In order to improve the sealing performance of the storage device, Figures 1 to 8 As shown, the present application adopts the following structure. Through the arrangement of the protective shell 12, the exhaust pipe 15, the piston plate 20 and the connecting rod 23, the sample storage device for sludge detection has the effect of facilitating the improvement of sealing performance. In actual use, after the sludge sample is stored in the storage chamber 2, the upper cover 13 is covered on the upper surface of the storage box 1, and the card slot 14 is stuck on the outer side of the upper surface of the storage box 1.
