The filter structure includes: a protective cover adapted to be fixed to the cabinet, which has a first opening facing downwards, forming an air inlet channel adapted to connect the first opening and the air inlet; the air inlet channel has a slot extending from the side near the cabinet to the side away from the cabinet, and the protective cover has an insertion port communicating with the slot at the corresponding position; and a filter element adapted to be inserted into or removed from the slot through the insertion port, and covering the air passage section in the corresponding air inlet channel after being inserted into place. This filter structure allows for convenient installation and removal of the filter element.

A kind of aerodynamic resistance device for floating wind turbine and floating wind turbine, including left wing and right wing, left wing and right wing are symmetrically fixed on the left and right sides of the cabin of wind turbine, left wing and right wing all include upper shell plate, lower shell plate, internal support beam, leading edge baffle and wing tip winglet, upper shell plate and lower shell plate are buckled into wing body with cavity, internal support beam is arranged in wing body, two ends of wing body are connected with the side of cabin and wing tip winglet respectively, leading edge baffle is rotatably installed on upper shell plate, its rotating shaft is parallel to the extension direction of left wing or right wing, leading edge baffle is connected with the driving mechanism for rotating it around its rotating shaft, to adjust the windward angle of leading edge baffle.The application can increase the wind area of the structure on both sides of cabin, increase aerodynamic resistance, and can adjust wind area according to actual wind condition, to adjust aerodynamic thrust, so as to inhibit the bow movement of wind turbine, realize the purpose of reducing angular displacement and improving power generation, and can ensure the stability of overall structure.

This utility model belongs to the field of new material manufacturing technology, and specifically relates to a coating uniform spraying device. The device is a housing, inside which is housed a pneumatic spray gun for spraying coating. The housing also contains a clamping assembly for holding the honeycomb panel, and a blowing device for blowing air. The blowing direction of the blowing device is opposite to the direction of the coating sprayed by the pneumatic spray gun. The housing has exhaust holes. Compared to existing technologies, this utility model, by incorporating a blowing device, solves the technical problem in existing technologies where, even with sufficient air pressure in the pneumatic spray gun, the coating easily passes through the honeycomb holes of the aramid honeycomb panel, leading to uneven spraying.

The utility model discloses a hair restraint structure of two -way air -out curling iron, aims at providing a hair restraint structure of two -way air -out curling iron can carry out flexible constraint to hair and avoid its sliding, it includes the air nozzle main part, its shape is cylindrical, and it is equipped with several air -out areas that are evenly distributed along the circumference of air nozzle main part on its lateral wall, several pieces of guide vane are detachably connected on several air -out areas and are located outside air nozzle main part, and the left and right side edges of guide vane and the lateral wall of air nozzle main part form the air outlet that blows to left and the air outlet that blows to right respectively, and the length direction of air outlet and the axial direction of air nozzle main part are parallel to each other, the outer surface of guide vane is the arc surface that left and right side edges are all inward buckling and the middle part is outward arched, and the outer surface of guide vane forms the wave shape structure of high and low undulation from one end to the other end. The utility model has the beneficial effect that can carry out flexible constraint to hair and avoid its sliding.

The utility model discloses an air duct assembly and an electrical cabinet. The air duct assembly comprises a first housing and a second housing. The first shell is provided with a first air duct; the second shell and the first shell are arranged in the first direction, and the second shell is provided with a second air duct; the second shell is suitable for being matched with the first shell so that the first air channel can communicate with the second air channel. The second shell at least protrudes relative to one surface of the first shell so as to guarantee the heat dissipation effect or be conveniently connected with other elements, the second shell is further suitable for being separated relative to the first shell, so that the elements are allowed to be mounted or dismounted in the first direction, only the second shell needs to be separated from the first shell, the first shell does not need to be dismounted, and the mounting and dismounting efficiency is improved. Therefore, the maintenance is more convenient.

This invention provides a dynamic mechanical structure wind vane ground-mounted landscape tower, relating to the field of communication landscape towers. It includes a landscape column, a flipping guide rod, a marker head, a marker tail, and an extension plate. The landscape column has two annular sub-tower structures on its upper and lower sides of its outer end face, symmetrically positioned. The landscape column's outer end face has four outward-facing adjustment cavities. This design uses a threaded connection to move a telescopic connecting cylinder outward, which in turn moves the connecting guide plate, and then, through transmission, moves the directional marker outward. As the directional marker moves outward, it makes it easier for pedestrians to understand the wind direction, providing a direct visual representation of the wind's direction. This design also deforms the extension plate, increasing the wind-receiving area of ​​the marker tail, thereby expanding the wind-sensing area and improving the wind vane's sensing accuracy. This facilitates adjustment and sensing of the wind direction angle, and the change in the dynamic mechanical structure enhances the wind vane's sensing effect.
