The application discloses a digital twin system construction method and device, electronic equipment and a storage medium, and relates to the technical field of electronic information. The method comprises the following steps: acquiring system description data corresponding to a target system; the target system comprises a plurality of nodes which are connected to each other in communication; performing analysis and processing on the node behaviors based on the system description data by using a twin system analysis model to obtain a node behavior model of each node; the node behavior model is used for indicating the node configuration and the node behavior of the corresponding node; instantiating a virtual node corresponding to each node in a virtual digital system; and configuring the virtual node corresponding to each node based on the node behavior model of each node to obtain a target digital twin system corresponding to the target system. According to the method, the cost and difficulty of constructing the target digital twin system are reduced.

The present application provides a flue gas purification device and method in asphalt mixture production, an electrostatic precipitator body and conduit, a pouring trough, an anode plate body, a mounting baffle and a filter bag. The present application operates the output shaft of a drive motor to rotate and drive the threaded rod to rotate, so that the threaded rod can thread the moving plate to move linearly. At this time, the moving plate can drive the scraper to scrape the dust on the surface of the anode plate body, and the two scrapers are distributed in an eight-shaped pattern, which can guide the dust on the surface of the anode plate body while scraping it to avoid dust accumulation on the surface of the scraper. At the same time, when the anode plate body is damaged and needs to be replaced, the fixed plate can be started to generate a pulling force to drive the second connecting plate to expand at a smaller angle, so that the fixed block is pulled to flip inward. At this time, the anode plate body can be moved out of the electrostatic precipitator body by moving the moving plate upward, so that the anode plate body can be replaced, achieving the effect of scraping and cleaning the anode plate body.

The waste gas treatment device comprises a box body, the front surface of the box body is communicated with a gas inlet pipe, the gas inlet pipe is provided with a first fan, the inner wall of the box body is fixedly connected with a dehumidification layer and an activated carbon layer, the top of the box body is communicated with an exhaust pipe, and the exhaust pipe is provided with a second fan. A second fan and a gas sensor are installed on the exhaust pipe, the exhaust pipe is communicated with two return pipes, the other ends of the two return pipes are communicated with the box body, and electromagnetic valves are installed on the two return pipes and the exhaust pipe. According to the waste gas treatment device, unqualified waste gas can be subjected to secondary treatment, the situation that waste gas treatment is difficult when the waste gas treatment is unqualified is effectively avoided, moisture in the waste gas can be filtered, the situation that the service life of activated carbon is affected by the moisture in the waste gas is avoided, and then the practicability of the device is improved.

This invention discloses a method and mold for cryogenic pressure forming of a large, high-strength cylindrical ring structure, relating to the field of metal sheet forming technology. The forming method includes: Step 1, determining the initial dimensions of the cylindrical ring blank and the required forming temperature based on the shape, size, and performance indicators of the target cylindrical ring structure; Step 2, cutting the flat plate, rolling and welding it into a straight-walled cylindrical ring blank; Step 3, placing the cylindrical ring blank in a mold, filling the space between the cylindrical ring blank wall and the mold with a cryogenic medium and applying pressure, causing the cylindrical ring blank to undergo plastic deformation under cryogenic conditions until it adheres to the mold surface, thus obtaining a cylindrical ring structure with weld seam reinforcement consistent with the base material. The solution provided by this invention can improve the performance and manufacturing efficiency of large cylindrical ring structures and reduce manufacturing costs.

The utility model discloses a drilling device for constructional engineering, which comprises a workbench, and four corners of the bottom of the workbench are fixedly connected with supporting legs. When building materials are drilled, the materials to be drilled are placed on the top of the adsorption assembly, after the movable block is pushed to the corresponding position, the fastening bolt is screwed, the movable block can be fixed, the first small electric cylinder is started, the first small electric cylinder drives the fixed block to move downwards, the second small electric cylinder is started while the fixed block moves downwards, and then the building materials are drilled. And a second small electric cylinder drives a connecting plate, a connecting column, a fixing plate, an atomizing spray head and a drilling assembly to move rightwards, and after the drilling assembly moves to a proper position, the building material can be drilled, so that the building material drilling device has the advantage of being convenient to drill, and when the building material is drilled, after the to-be-drilled material is placed at the corresponding position, the drilling efficiency is improved. And the building materials can be automatically drilled without manually adjusting the positions of the building materials by workers, so that the drilling time of the building materials is shortened.

The utility model discloses a bending-adjustable microcatheter handle and a bending-adjustable microcatheter, and belongs to the technical field of medical instruments, the bending-adjustable microcatheter handle comprises a traction wire and a Y-shaped seat, the Y-shaped seat comprises a main branch tube and a side branch tube intersecting with the axis of the main branch tube, one end of the traction wire sequentially penetrates through the main branch tube and is fixedly connected with the end part of the side branch tube, and the other end of the traction wire is fixedly connected with the handle. The other end is fixedly connected with a component connected with the far end of the main branch pipe; a rotating handle rotating cap and a push-pull device are arranged on a bottom pipe of a side branch pipe to be matched with a traction wire, so that the push-pull device moves back and forth in the axial direction of the bottom pipe, and then a fixing buckle connected with the traction wire in a push-pull shell is pushed backwards to complete the bending adjustment action of the traction wire.
