10results about How to "Improve wind stability" patented technology

The application discloses a windproof device and method for improving the safety of a unit curtain wall, which comprises a base, an adsorption assembly, a winch, a cable, a counterweight assembly, a buffer tire assembly and a handrail. The adsorption assembly adsorbs and fixes the base to the surface of the unit curtain wall, the winch tightens the cable, so that the unit curtain wall is in tension constraint with the hook, the temporary anchor point or the adsorption fulcrum, thereby inhibiting the rotation and swing in the hoisting process; the counterweight assembly lowers the gravity center, the buffer tire assembly absorbs the in-place impact, and the handrail facilitates manual fine adjustment and positioning. The application can reduce the traditional cable wind rope layout, and improve the hoisting safety and efficiency of the unit curtain wall.

The application belongs to the technical field of coil assembly, and discloses a double-cake coil winding device and a winding method. The device comprises a back plate, a first spool, a second spool, a first winding disc and a second winding disc. A framework is arranged on the back plate, and the outer wall of the framework forms a winding area. An insulating plate separates the winding area into a first winding area and a second winding area, and the insulating plate is provided with a crack. The first spool passes through the back plate and the framework. The second spool is arranged outside the back plate and can rotate. The first winding disc has a first state and a second state. The second winding disc is sleeved on the second spool. When the first winding disc is in the first state, the second winding disc is removed, and the first winding disc is in the second state. The first spool drives the back plate, the framework and the first winding disc to rotate synchronously. Part of the wire is wound on the first winding disc, and the other part is wound on the second winding disc through the crack. Through the application, a single wire can be wound into a double-cake coil, the shape stability of the coil winding is improved, and wire disconnection is avoided.

The application provides a straight rod stabilizing device based on a spiral structure blade, which comprises a straight rod, a spiral blade structure, a ball bearing and a thrust bearing; the outer layer of the straight rod is connected with the spiral blade structure; the upper and lower ends of the spiral blade structure are movably connected with the ball bearing and the thrust bearing; the application can improve the wind stability; the device can effectively improve the wind stability of objects (such as buildings, bridges, telegraph poles, billboards and the like) exposed in a high wind speed environment, reduce the possibility of being affected by wind force, and reduce the production and maintenance costs; through the detachable design, the spiral blade structure is independently installed, the cost increase caused by integral molding can be avoided in the production process, the maintenance and replacement can be more convenient, the maintenance cost is reduced, meanwhile, through the 3D printing technology and the like, the material cost can be reduced in the manufacturing process, and the structure weight is reduced.

This utility model discloses a portable outdoor tent, including a tent body with cover plates connected to both sides of the tent body. When using this utility model, the user can take out the deflated and rolled-up nylon support columns from the support frame storage bag, then open the manual air valve and sealing plug on the air hose, inflate the support nylon support columns with an air pump, and then insert the formed support nylon support columns into the corresponding assembly fabric sleeves on the outer wall of the tent body. Using the connecting action of fixing hooks and fixing rings, the top of the initially assembled support nylon support columns is connected and fixed to the top of the tent body. Furthermore, by using support nylon support columns with a TPU wear-resistant coating to replace the commonly used metal poles, the tent can be deflated and rolled up for storage. It is lighter than traditional external support frame structures, reduces space requirements, and is easy to carry.

This application discloses a photovoltaic-driven soil moisture feedback irrigation device, comprising: a main body, a water storage tank, an electrical box, a photovoltaic module, and a sprinkler assembly. The photovoltaic module is installed on the top of the main body. The electrical box and the water storage tank are sequentially arranged on the main body and located below the photovoltaic module. The sprinkler assembly is disposed on the outer peripheral wall of the water storage tank and connected to the interior of the water storage tank. The electrical box contains a control component for the photovoltaic module. The bottom of the main body is conical and is equipped with a humidity sensor for detecting soil moisture. The humidity sensor is electrically connected to the control component, and the control component is electrically connected to the sprinkler assembly to control the sprinkler assembly to start spraying water. This device can adaptively adjust the spray volume according to the soil moisture conditions to achieve a reasonable irrigation effect.

This invention discloses the structure and construction method of an arch bridge viewing platform. The specific structure includes a main beam, with prefabricated platform sections symmetrically arranged on both sides of the main beam along the bridge's centerline. The outer walls of the prefabricated platform sections are connected to cantilevered splicing sections. The ends of the two cantilevered splicing sections furthest from the bridge's centerline coincide with the ends of the main beam. End caps are provided at the ends of the main beam. The inner walls of the prefabricated platform sections are connected to main arch ribs. This invention's arch bridge viewing platform structure solves the problem of poor overall structural integrity in existing arch bridge viewing platforms. The construction method of this invention is simple to operate and allows for rapid construction.
