This invention proposes a method for assembling a lightweight derrick, comprising the following steps: preparing an assembly site and configuring embedded ground bells; disassembling the derrick body into four components: upper, upper right, lower left, and lower right, respectively labeled a, b, c, and d; horizontally assembling components c and d, pre-tightening structural bolts; vertically assembling components b, c, and d together; horizontally assembling component a, installing outfitting parts, and erecting the assembly; hoisting component a onto components b, c, and d; and installing and laying pipelines, cables, and equipment between the components to complete the derrick assembly. This invention provides clear visibility of the straightness, verticality, and overall dimensions of the main structure in a horizontal configuration, allowing for more precise and clear control; it grounds high-altitude operations, greatly reducing construction difficulty and improving efficiency; it is applicable to the assembly of all lightweight derricks, has wide applicability, and improves the safety and efficiency of the entire construction process.

The application relates to the technical field of radio frequency antennas and electromagnetic super surface, and particularly discloses an orbital angular momentum super surface based on an ITO conductive layer and an implementation method, wherein the super surface is composed of a plurality of transmission type super surface units arranged in a two-dimensional array, each transmission type super surface unit comprises a horizontal parallel rectangular grating, four layers of transparent glass substrates and a vertical parallel rectangular grating which are sequentially and layerwisely arranged, the upper surfaces of the second and fourth layers of transparent glass substrates are provided with square frame structures, the upper surface of the third layer of transparent glass substrates is provided with a square frame and a modified I-shaped resonance unit; the rotation angle of the modified I-shaped resonance unit in each unit is adjusted according to the phase compensation value required by each transmission type super surface unit, so that a composite phase distribution is formed on the aperture surface of the two-dimensional array. The application has the advantages of optical transparency, wideband phase control capability, polarization conversion capability and multi-beam orbital angular momentum beam generation capability, and is suitable for intelligent glass, transparent window communication and multi-dimensional multiplexing wireless communication scenes.

The application discloses a kind of based on computer vision's intelligent playing card dispensing device and method.The device includes computer vision identification module, mechanical card turning mechanism, automatic shuffling mechanism, intelligent dispensing mechanism and man-machine interaction module.The computer vision identification module is automatically judged playing card front and back by camera and image processing algorithm;The mechanical card turning mechanism is turned into back up with face up playing card;The automatic shuffling mechanism adopts cut card type shuffling, supports fixed or random shuffling times;The intelligent dispensing mechanism is equipped with rotatable card outlet, and can be sequentially distributed to 2-6 players from the specified player in clockwise / anticlockwise direction;The device supports three sets of 162 playing cards at most.The application solves the problems of uncontrollable card face direction, insufficient shuffling randomness and inaccurate dispensing rule execution in manual dispensing, and realizes the full-process automation of playing card processing.

This invention discloses a hole protector retrieval tool, comprising a tool body with a sealing buckle at the upper internal end and an anti-rotation block at the lower part. A first hydraulic channel, a second hydraulic channel, a third hydraulic channel, and a fourth hydraulic channel pass through the tool body. A first sealing cavity, a second sealing cavity, a third sealing cavity, and a fourth sealing cavity are provided on the outer periphery of the tool body. An upper cylinder is threadedly connected to the upper external end of the tool body. The upper cylinder has a hollow structure with a concave lower end. A lower cylinder is located within the lower hollow structure of the upper cylinder. The outer wall of the lower end of the lower cylinder has a concave surface, and several clamps are evenly fixed to the concave surface by screws. This invention also discloses a hole protector retrieval method. The hole protector retrieval tool and method of this invention solve the problem that the existing hole protector retrieval tools are prone to uneven loading or jamming during the C-ring connection process, making it difficult to detach underwater. This simplifies the operation steps and enables rapid connection and retrieval of the hole protector.
