The utility model provides a paper thickness detection device for paper mill workshop, its characterized in being including support structure, pretreatment structure, detection structure, the one side of support structure is provided with pretreatment structure, detection structure, support structure and pretreatment structure, detection structure are connected through bolt, nut, the utility model of improvement pretreatment structure, the pretreatment structure that is composed of telescopic cylinder B, pressing plate, rubber protection sleeve, paper dust dust catcher, collection box, telescopic cylinder B can drive pressing plate and realize accurate up and down movement, through the stable pressure of exerting is even to paper and carries out the even processing, can effectively eliminate paper because of transport, the wrinkle, curling etc. of stacking generation, even after the paper thickness distribution is more even, can pressing plate one side through the rubber protection sleeve connected of adhesive way, avoid the hard pressing plate direct contact and lead to paper edge breakage, indentation or tear, especially suitable for processing thinner, easily broken paper, reduce production cost.

The application discloses a gas diffusion module of a fuel cell, a fuel cell and a preparation method. The gas diffusion module comprises a substrate layer and a microporous layer which are arranged in sequence. The substrate layer is provided with a first hole group and a second hole group. The first hole group and the second hole group are both provided with micro-perforations. The hydrophobicity of the micro-perforations on the first surface is greater than that on the second surface. The pore diameter of the micro-perforations located in front of the air flow direction in the first hole group and the second hole group is greater than that of the micro-perforations located behind the air flow direction. Alternatively, the opening density of the micro-perforations located in front of the air flow direction in the first hole group and the second hole group is greater than that of the micro-perforations located behind the air flow direction. On any homologous line perpendicular to the air flow direction, the opening density of the micro-perforations of the first hole group is greater than that of the micro-perforations of the second hole group, and the pore diameter of the micro-perforations of the first hole group is smaller than that of the micro-perforations of the second hole group. The water in different positions of the cathode surface is kept relatively balanced, and water accumulation and excessive water loss are prevented.

The utility model discloses an automatic closed soft soil sampler, including outer sleeve, inner sleeve, guide cone, mud inlet hole and outer cone cover, the bottom fixedly connected with guide cone of outer sleeve, the bottom lateral wall of outer sleeve is equipped with mud inlet hole, and the outer cone cover of mud inlet hole and guide cone outside is covered in the bottom of outer sleeve, and the bottom fixedly connected of outer cone cover and outer sleeve, the inner sleeve is movably connected in the inside of outer sleeve, and the inner sleeve top is installed with the push handle mechanism extending to the outside of outer sleeve, and the inner sleeve has two position attitudes under the cooperation of first stop groove, second stop groove and limit pin, thereby can be in sampling, make the inner sleeve be in high position, thereby convenient soft soil passes through the clearance fit of outer cone cover and guide cone and enters the mud inlet hole into the inner sleeve and is collected, can make the inner sleeve be in low position state simultaneously after sampling, thereby through the guide cone and seal the bottom opening of inner sleeve, avoid the soft soil falling when sampler and take out.
