The utility model relates to the technical field of raw material mixing equipment, and discloses raw material mixing equipment for producing a wear-resistant shock pad, which comprises a bearing frame, a sealed sealing groove is arranged at the upper part of the bearing frame, a conical mixing barrel for mixing is arranged in the sealing groove, and an inner cavity of the conical mixing barrel is in a conical shape with a wide upper part and a narrow lower part. According to the utility model, the inner cavity is in the shape of the inverted cone, the first driving motor drives the mixing frame to rotate, raw materials move towards the periphery under the action of centrifugal force, the diameter of the conical mixing barrel is gradually reduced from top to bottom, a gradient type constraint space is formed, and the raw materials at the inner bottom of the conical mixing barrel are pushed upwards; circumferential flow driven by centrifugal force is coupled with reaction force of the wall surface, so that a spiral ascending flow state is formed, the mixing efficiency of the raw materials is improved, unmixed raw materials are not left at the bottom in the conical mixing barrel, and the mixing efficiency of the raw materials is improved.

The utility model discloses a kind of high-temperature-resistant conductive foam, including foam body, its foam body outer wall is equipped with heat insulation sleeve, the heat insulation sleeve outer wall is equipped with fire-retardant sleeve, the fire-retardant sleeve outer wall is equipped with conductive cloth, the utility model relates to conductive foam technical field;The high-temperature-resistant conductive foam, by tearing off release film and movable foam body is adhered to the position on the top of workpiece by the adhesion of adhesive layer, and by the mutual cooperation of fire-retardant sleeve and heat insulation sleeve under work, so that foam body has good high temperature resistance and avoids the occurrence of spontaneous combustion, under the cooperation of heat dissipation bar and heat dissipation port, heat inside foam body can be emitted outward, with good heat dissipation effect, by the mutual cooperation of reinforcing rib and connecting seat under work, so that foam body has good strength, when being pressed or receiving external impact, can prevent the problem of deformation damage of whole.

The utility model relates to the technical field of cold-contraction cable joints, in particular to a power cable cold-contraction intermediate joint, which comprises a joint pipe, a shielding net is mounted in the pipe wall of the joint pipe, an insulating layer is mounted in the middle of the inner wall of the joint pipe, and a plurality of high-temperature-resistant sleeves which are uniformly arrayed are mounted on the inner wall of the insulating layer. Shielding contact sleeves are installed on the inner sides of the two ends of the inner wall of the connector pipe, sealing sleeves are installed on the outer sides of the two ends of the inner wall of the connector pipe, and the outer surface of the connector pipe is coated with a shielding coating. The cable joint has the advantages that the shielding net is filled in the joint pipe, and the shielding contact sleeves are arranged on the inner sides of the two ends in the joint pipe and are connected with the shielding net, so that after two cables extend into the joint pipe, the shielding contact sleeves are in contact with the cables to form a loop and play a role in shielding electric signals; the insulating layer is installed in the middle of the interior of the joint pipe, and the insulating layer can block electrical conduction of the cable, so that the cold contraction joint is not conductive.
