Abstract: The present invention discloses a bionic high holding power anchor, which includes an anchor rod, a suspension clasp coupled with one end of the anchor rod and an anchor fluke hinged with the other end of the anchor rod, wherein a plurality of fluke heads arranged at equal intervals are extended from a front end of the anchor fluke, fin-like streamlined balance wings are arranged at two sides of the anchor fluke; the fluke head is in a shape of triangle-like taper containing a plane side wall and two curved side walls, the plane side wall is an isosceles triangle, the two curved side walls are smooth curved surfaces, and the two smooth curved surfaces are symmetrical around a normal plane of the plane side wall.

Abstract: A device and method for adjusting a fuel supply advance angle of a multi-cylinder diesel engine includes a gear chamber, a connecting disc and a fuel pump, wherein the gear chamber and the connecting disc are in the diesel engine, and the fuel pump is at a left end surface outside the gear chamber. A main shaft end of the fuel pump extends into the gear chamber. A right end surface of the connecting disc connects to a timing gear. A right end surface of the timing gear has three penetrating circular-arc waist-shaped holes. Annular sizing blocks are arranged on the waist-shaped holes. A penetrating circular hole is at a tail end of the waist-shaped holes. The circular hole is provided with a T-shaped nut. A support screw is arranged in the T-shaped nut, and the screw head of the support screw is jacked against the annular sizing block.

Abstract: An infrared vision sensing detection method and device for narrow-gap weld seam deviation are provided. The device includes a shaking (or rotating) arc narrow-gap welding torch, an arc current sensor, a computer image processing system, and an infrared photographing system. The infrared photographing system includes an infrared camera which acquires an infrared image of a welding region in an external triggering manner when an arc shakes (or rotates) to a position closest to the left side wall or right side wall of a groove. After computer image processing, a welding wire position and a groove edge information is extracted in real time, and a weld seam deviation is calculated according to position changes of a welding wire relative to the left side wall and the right side wall of the groove, and the weld seam deviation is output.

Abstract: Disclosed is a crosshead component of a large diesel engine. The crosshead component consists of a crosshead pin (1), slide blocks (2), wear-resisting plates (3), sealing covers (4), and a sleeve (5), and has a structure with H-shaped cross and longitudinal sections. The crosshead pin (1) is a cylinder provided with petal-shaped through holes. The slide blocks (2) are respectively fitted on and connected to outer circles of left and right ends of the crosshead pin (1). The sleeve (5) is inserted in and connected to the petal-shaped through holes (112) of the crosshead pin (1) to form oil inlet/return way cavities. Left and right end surfaces of the crosshead pin (1) are respectively connected to the sealing covers (4) for sealing the oil way cavities. Front and back ends of the slide blocks (2) are respectively connected to the wear-resisting plates (3). The crosshead component has excellent interchangeability, economy and convenience.

Abstract: Disclosed are an infrared vision sensing detection method and device for narrow-gap weld seam deviation. The device includes a shaking (or rotating) arc narrow-gap welding torch, an arc current sensor (3), a computer image processing system (15), and an infrared photographing system. An infrared camera (11) acquires an infrared image of a welding region in an external triggering manner when an arc (1) shakes (or rotates) to a position closest to the left side wall or right side wall of a groove (9). After computer image processing, welding wire position and groove edge information is extracted in real time, and weld seam deviation is calculated according to position changes of a welding wire relative to the left side wall and the right side wall of the groove, and the weld seam deviation is output.

Abstract: A bionic pectoral fin propelling device based on a planetary gear train, including a frame, a power source (1), a propelling part (2), left and right maneuvering parts (3), a fixed support plate (4), a movable support plate (5), a left pectoral fin (6), a right pectoral fin (7), a fish body (8), and a tail fin (9). The fixed support plate (4) and the movable support plate (5) are installed on the frame parallel to each other; the fixed support plate (4) is located in front of the movable support plate (5); and the left and right maneuvering parts (3) are located between the fixed support plate (4) and the movable support plate (5). The present invention solves the problem that the two pectoral fins are not synchronized, realizes variable speed propelling and left/right maneuvering, facilitates increasing the bearing capacity of the propelling device, and is particularly suitable in limited space applications.
