摘要： The invention relates to the technical field of 3D printing, in particular to a multi-functional concrete 3D printing device and a use method. The multi-functional concrete 3D printing device includes: a control structure including a control chamber and an arm lever, wherein a controller of the control chamber is in transmission connection with the arm lever to control the action of the arm lever; a printing structure, being disposed at an end of the arm lever away from the control chamber, being connected to the arm lever, and including a print carriage, a nozzle disposed on the print carriage, and at least one adjustable leg disposed on the print carriage, wherein an angle adjusting member and a nozzle yaw power member are disposed between the print carriage and the arm lever, the nozzle is provided with an angle rotating member, the controller controls the extension length of the leg to cause the angle adjusting member to drive the print carriage to rotate, and the nozzle sprays from different angles by rotation of the print carriage, and rotation of the nozzle yaw power member and the angle rotating member. The multi-functional concrete 3D printing device solves the problem that the 3D printing devices cannot efficiently perform non-horizontal plane printing such as ramp protection.

摘要： The present invention relates to the technical field of engineering machines, in particular to a gantry crane (1) lightning protection device, a machine and a use method thereof. The gantry crane (1) lightning protection device includes:a rotatable rod (2) structure, including a rotatable rod (2), wherein the rotatable rod (2) is fitted inside an insulating sleeve (13) of a gantry crane (1); an umbrella net structure (11), including a guide sleeve (3) threadedly and rotatably connected with the rotatable rod (2) in a sleeving manner, wherein the guide sleeve (3) is arranged on an outer circumference of the rotatable rod (2), conductive longitudinal rods (4) are arranged at intervals on the guide sleeve (3), and conductive cross-rings are arranged at intervals and around the conductive longitudinal rods (4);the radii of the conductive cross-rings are different from each other so that the heights of positions are also different from each other when the umbrella net structure (11) is unfolded;and a conductive structure, including a conductive wire (14) and a grounding carbon rod (15), wherein one end of the conductive wire (14) is fixedly connected with the rotatable rod (2), the other end thereof is connected with the grounding carbon rod (15), and in a lightning protection state, the conductive longitudinal rods (4) extend out of the insulating sleeve (13), the conductive cross-rings unfold along the circumferential direction of the conductive longitudinal rods (4) into an umbrella shape, and the conductive cross-rings and the conductive longitudinal rods (4) together form an umbrella-shaped structure, so that the gantry crane (1) is shielded from lightning, wherein lightning is transmitted to the conductive wire (14) by the rotatable rod (2), and finally transmitted to the ground by the conductive wire (14) via the grounding carbon rod (15). The invention solves the problem that the gantry crane (1) can not be covered by the lightning rod, and as a result, the protection effect is affected.

摘要： The present invention discloses a self-maintaining anti-scouring device for an offshore wind farm pile foundation, which relates to the technical field of pile foundation anti-scouring. The self-maintaining anti-scouring device comprises a fixing portion which is fixedly arranged on the seabed; a mounting portion which is arranged above the fixing portion and is used for mounting wind power equipment; and a sand screening portion which comprises a sand screening ring and an impeller arranged below the mounting portion. The sand screening ring is sequentially provided with a water inlet, a stirring cavity and a sand outlet from top to bottom. A drainage hole in communication with the stirring cavity is formed in the side face of the sand screening ring. The impeller is rotatably arranged in the stirring cavity. In the present invention, the impeller rotates horizontally in the sand screening ring such that silt and seawater are separated under the action of centrifugal force and are respectively discharged from the sand outlet and the drainage hole. At the same time, seawater enters the stirring cavity from the water inlet, and the separated silt falls to the periphery of the fixing portion, so as to prevent the foundation layer on the periphery of the fixing portion from falling off and being pitted due to wave scouring, thereby achieving anti-scouring purposes.
