The invention discloses a combined cable bridge flexible compensation device, which comprises a first panel and a compensation plate; one side of the first panel is provided with a second panel; an embedded mesh layer is respectively fixed inside the first panel and the second panel; the respective surface connection end of the first panel and the second panel is welded with a connection hinge; afastening bolt is arranged through the interior of the connection hinge; the left and right side walls of the first panel and the second panel are respectively welded with a side plate; the inner sideof the compensation plate is provided with a screw in a penetration manner; and the compensation plate is located below the second panel. In the combined cable bridge flexible compensation device, the bottom sealing plate itself has good compression and extension capability, carries out corresponding deformation matched with the telescopic expansion of the bridge body, and has the same function as the arc structure of the first panel and the second panel, both of which weaken the direct stretching action of the bridge body to the cable, and separate the cable from the bridge body so as to avoid excessive friction between the cable and the bridge body, resulting in cable damage.

The invention discloses a preparation method of a topological elastomer with a highly branched structure and low modulus and high elasticity. The topological elastomer contains dendritic branched macromolecules, and the preparation method comprises the following steps: mixing a plurality of monomers by a direct cross-linking method, reacting, and simultaneously carrying out cross-linking reactionand highly branched structure forming reaction to directly obtain the topological elastomer; or a post-crosslinking method: firstly synthesizing dendritic branched macromolecules with a highly branched structure, and then crosslinking the dendritic branched macromolecules by using a crosslinking agent to obtain the topological elastomer; or a grafting method: grafting unreacted monomers or dendritic branched macromolecules into the polymer network to form the topological elastomer; or a copolymerizing method: copolymerizing unreacted monomers or dendritic branched macromolecules and a polymernetwork to form a network or double-network / interpenetrating network elastomer. The topological elastomer prepared by the preparation method can realize low modulus on the premise of keeping high elasticity.

The intelligent pressure reducing valve can spontaneously generate power, is stable in power generating performance and has the data acquisition, processing and display functions.

The invention relates to an elastic supporting anti-slip splash-proof shoe sole which comprises an insole, a bottom piece and front and rear supporting parts assembled on the side walls of the insole. Each supporting part is composed of a plurality of elastic supporting bodies, each supporting body is composed of a vertical portion extending in the height direction of the shoe sole and a horizontal portion extending in the width direction of the shoe sole, and the lower ends of the vertical portions are integrally connected with the outer ends of the horizontal portions to form an L shape. The upper ends of all the vertical portions are integrally connected through connecting strips, and the connecting strips are fixedly connected with the side walls of the insole. Anti-slip protrusions are further arranged on the bottom edge of the outer side wall of the vertical portion of the rear supporting part. The inner ends of all the horizontal portions are integrally connected and are clamped between the insole and the bottom piece. The configured front and rear supporting bodies enable the shoe sole to have conformable, shock-absorbing, supporting and side turn preventing functions, the bottom piece, the front supporting bodies and the rear supporting bodies can respectively provide a good assistance effect on the foot, and the exercise efficiency can be improved. The arranged bottom piece structure enables the shoe sole to have good water drainage property and road holding capacity.
