The utility model provides a torsional spring device for resisting eccentric torque of tracking photovoltaic support, including support subassembly and resilience subassembly. Support subassembly is installed in non -driven stand one side and parallel interval in photovoltaic main beam below, and resilience subassembly is sleeved on photovoltaic main beam, and one end is connected purlin, and the other end is installed in support subassembly. Photovoltaic main beam rotates and makes resilience subassembly deformation, and resilience subassembly applies reverse force to purlin, and the balance purlin and photovoltaic module gravity influence. Resilience subassembly is equipped with two and is symmetrical, and torsional spring one positive one negative assembly, ensure that purlin always presses torsional spring when main beam rotates plus or minus 60 degrees. The device can solve the problem that the support angle is pressed down by gravity, and the structure is simple and practical.

The utility model discloses a floor type warmer, include: at least three heating components of interval arrangement along the circumferential direction and the support plate of being connected with at least three heating components simultaneously, and the lampshade shell for covering and setting above at least three heating components be connected with the support plate, and the panel be connected with the lampshade shell, wherein the panel is hollow and is formed with the hole of giving place suitable for one -to -one embedding of at least three heating components, the panel still is connected with the floor support column, and every heating component all includes the reflection cover of forming heat reflection cavity and the heating device of being located in the reflection cover.

The utility model discloses an atomization assembly and an atomization device, the atomization assembly comprises an outer support, an inner support, an atomization core, an oil control piece and a compression ring, both the outer support and the inner support are of hollow structures, the atomization core is installed in the inner support, the inner support is installed in the outer support, the oil control piece is sleeved on the periphery of the inner support, and the oil control piece is located in the outer support; the outer support is provided with a first liquid guide hole, the inner support is provided with a second liquid guide hole, the atomizing core is arranged opposite to the second liquid guide hole, and the oil control piece is arranged opposite to the second liquid guide hole and the first liquid guide hole; the pressing ring is used for being arranged on the periphery of the end of the inner support in a sleeving mode and matched with the end of the outer support. The part structure of the atomization assembly is relatively simple, the overall structure is convenient to assemble, automatic production can be achieved, and the production efficiency can be effectively improved.

The invention belongs to the technical field of constructional engineering construction machinery, and particularly relates to an oblique traction in-place tool and a using method. Comprising a plurality of first connecting lugs arranged on the surface of a steel ball body, a plurality of second connecting lugs fixed to the spherical exhibition hall and traction assemblies arranged between the first connecting lugs and the second connecting lugs, guide wheel sets are arranged on the two sides of the second connecting lugs at intervals, and traction cables are arranged on the guide wheel sets; one end of each traction cable is connected with a winch installed on the spherical exhibition hall, the other ends of the traction cables are jointly connected with the corresponding traction assemblies, and each traction assembly comprises a fixed lock head corresponding to the first connecting lug, an adjustable lock head corresponding to the second connecting lug and a steel inhaul cable arranged between the adjustable lock head and the fixed lock head. By the adoption of the technical scheme, the problem that a worker needs to continuously adjust stress balance of a steel ball due to the fact that an existing steel inhaul cable deforms after traction is completed can be effectively solved.
