The invention relates to a telescopic support type multi-eye wireless pipeline detection robot. The telescopic support type multi-eye wireless pipeline detection robot comprises a bearing machine body, walking mechanisms, telescopic drive mechanisms, pipeline detection sets and a control system. The bearing machine body is of a cavity structure with the rectangular cross section. The totally fourwalking mechanisms are arranged, evenly distributed around the axis of the bearing machine body and are connected with the side surfaces of the bearing machine body through the telescopic drive mechanisms. At least four pipeline detection sets are arranged and evenly distributed on the upper end face and the lower end face of the bearing machine body around the axis of the bearing machine body. The control system is embedded in the bearing machine body and electrically connected with the walking mechanisms, the telescopic drive mechanisms and the pipeline detection sets. According to the telescopic support type multi-eye wireless pipeline detection robot, on one hand, the requirement for automatic detection work on the interiors of pipelines with the circular cross sections and the regularpolygons can be effectively met, detection data are comprehensive, and the data communication capability is high; and on the other hand, during detection running operation, the situation of pipelineinner wall scratching due to the too high contact face pressure is effectively prevented, and the detection work reliability is greatly improved.

The invention provides a multilayer metal coupling deformation rolling combined method and device. The device comprises a compound blank heating furnace, a high-pressure water descaling machine, a four-roller reversible rolling mill, a front reeling holding furnace, a rear reeling holding furnace, a front board criss cross bending deformation unit, a rear board criss cross bending deformation unit, a laminar cooling unit and a finished product reeling machine. According to the method, the reeling heating furnaces are equipped in front of and in rear of the single-frame four-roller reversible rolling mill, and the tension bending units are arranged between the front reeling furnace and the rear reeling furnace, the tension bending rollers are flower rollers of which the surfaces are of a convex and concave structure, three flower rollers form a reverse bending deformation unit, and a convex-concave structure of a front roller surface and a convex-concave structure of a rear roller surface are arranged in a staggered mode, so that a temperature controlling reeling coupling deformation rolling combined mechanism used for applying tension and achieving board criss cross bending deformation is formed, residual stress of a compound interface is remarkably reduced, and board shape quality is ensured; and meanwhile, the bonding strength and binding rate of the compound interfaces are greatly improved, the structure performance and comprehensive mechanical performance of composite boards are improved, and the production efficiency and yield are remarkably improved.

The invention discloses a micro bacteria cracking reactor based on surface acoustic waves and a bacteria cracking method. The reactor comprises a lower bottom plate and an upper cover plate which arealigned and bonded together; a group of surface acoustic wave generation structures are arranged on the lower bottom plate; a groove is formed in one side of the upper cover plate, and a micro-channelstructure allowing liquid to flow through is arranged in the middle of the upper cover plate; a signal control system is used for controlling the surface acoustic wave generation structures; the micro-channel structure comprises a sample introduction hole, a reaction area and a product outflow hole. The method is suitable for cracking different types of bacteria, does not need any chemical reagent, and avoids the pollution of the chemical reagent to a cracked product.

The present invention relates to an injection pump for internal combustion engine which has at least one piston (10), wherein, a pump chamber (11) and a high pressure chamber (12) connected via two suction holes (13) work together with the piston or each piston (10) in order to make the piston or each piston (10) close the suction hole or each suction hole (13) at a first position and to restrain the fuel flow from the pump chamber (11) to the high pressure chamber (12), and the piston or each piston (10) will release the suction hole or each suction hole (13) at a second position in order to fill the high pressure chamber (12) with fuel from the pump chamber (11). The suction hole or each suction hole (13) has a cylinder type section (17) adjacent to the high pressure chamber (12), wherein, the cylinder type section (17) is connected with at least two truncated cone shape sections (19, 20), the axes (21) of which rotates or declines relative to the axes (18) of the cylinder type section (17) in horizontal direction or vertical direction.
