This invention discloses the application of ZmDOF36 in regulating plasmodesmata development and sucrose transport in seeds, belonging to the field of plant genetic engineering technology. The technical problem solved by this invention is how to regulate the absorption and / or transport capacity of sucrose in plant seeds and the development of plasmodesmata. The ZmDOF36 disclosed in this invention is a protein with the amino acid sequence SEQ ID No. 2. ZmDOF36 After gene knockout, plasmodesmata morphology changed significantly, the number of branches decreased, the efficiency of sucrose transport to the endosperm tip decreased, and seed weight decreased; ZmDOF36 After the gene was introduced into plants, the number of plasmodesmata branches increased, the transport efficiency of sucrose to the endosperm tip was significantly improved, and the seed weight increased. This demonstrates the core application potential of ZmDOF36 in regulating plasmodesmata morphology in plant seeds, optimizing sucrose transport efficiency, and increasing seed yield.

This utility model discloses a lifting device for PT connecting sleeves, relating to the field of installation equipment technology. The lifting device for PT connecting sleeves includes a base and a hanger located in the middle of the top surface of the base. It also includes a slider slidably connected to the top left side of the hanger, with a fixing mechanism fixedly connected to the bottom of the slider. Through the fixing mechanism, when the device is to be used, the external PT connecting sleeve is first passed through a suspension rope, and then secured using the rope loops and fixing buckles inside the suspension rope. Next, the lifting hydraulic rod is raised, allowing the sleeve to rise with the fixing plate for further transportation. This facilitates the securing and lifting of the connecting sleeve during transportation, preventing tilting and detachment during transport due to inadequate or insufficient securing, which reduces transportation efficiency and increases the damage rate of the connecting sleeve.

This invention relates to the field of natural gas pipeline cleaning technology, specifically disclosing a vortex jet-type pipeline cleaning device for natural gas pipelines. The device includes an outer cylinder, an inner cylinder housed within the outer cylinder and coaxially aligned with it, several sets of jet pipes disposed at one end of the inner cylinder and communicating with it, and an impeller assembly housed on the outside of the inner cylinder. The ends of the jet pipes away from the inner cylinder face the natural gas pipeline. The inner cylinder and outer cylinder are rotatably coupled. This invention controls the rotation of the inner cylinder under the drive of natural gas through the impeller assembly, causing some of the natural gas to pass through the jet pipes and form a vortex jet of gas, which is directly sprayed onto the inner wall of the natural gas pipeline, thereby purging dirt and impurities inside the pipeline. This prevents the accumulation of dirt and impurities from causing blockages in the natural gas pipeline and reducing the efficiency of natural gas pipeline transportation.

This utility model relates to a gas cylinder transport vehicle, belonging to the field of fire protection engineering technology. Specifically, it is a multi-functional gas cylinder transport vehicle, including a flatbed frame, a fixing rod, a connecting frame, and a placement rack assembly. The fixing rod is fixedly installed on one side of the surface of the flatbed frame, and a sleeve is fixedly installed at one end of the fixing rod. The connecting frame is disposed inside the sleeve, and a steering wheel is provided at the bottom of the connecting frame. The placement rack assembly includes a support rod fixedly installed on the flatbed frame. This utility model achieves the effect of improving operating efficiency while meeting green environmental protection requirements. It solves the problems of the patented adjustment component relying on locking parts and movable connecting adjustment rods, which requires manual adjustment and locking of the position, is cumbersome, relies on manual pushing, and has low transportation efficiency. In addition, it only targets the transportation of gas cylinders and does not consider the transfer needs of other materials. The adjustment component occupies space and cannot be stored.
