Description

Technical Field

[0001] The utility model belongs to the technical field of coating stirring, and in particular relates to a polyurea mixing device applied to an offshore photovoltaic bracket. Background Art

[0002] With the development of society, the demand for energy is increasing. With the consumption of non-renewable energy such as oil and natural gas and the enhancement of people's environmental awareness, clean energy has developed rapidly in countries around the world. Wind power, as a clean energy, has also received more and more attention. The sea surface is wide and the wind is strong, so there will be greater benefits in installing wind power equipment on the sea surface. However, since seawater contains more chloride ions with strong permeability and strong corrosive destructiveness, and the contact area between seawater and air is large and the convection is sufficient, the seawater will evaporate in large quantities under the constant stirring of waves and exposure to the sun, which will cause serious corrosion to offshore wind power equipment and affect the safety and service life of offshore wind power equipment.

[0003] In the prior art, during the construction of offshore wind turbines, anti-corrosion coatings are sprayed on the surface of the equipment to reduce the impact of seawater corrosion. Currently, offshore power equipment uses polyurea as an anti-corrosion coating. Polyurea coatings use a one-time coating process. No matter how large the area is, there are no joints. In addition, polyurea coatings are a dust-free material with the characteristics of strong adhesion, friction resistance, and high hardness. However, before use, two different components of polyurea coatings need to be mixed in a 1:1 ratio. Uneven mixing will affect the effect of polyurea coatings. Existing polyurea mixing and stirring equipment generally mixes by rotating a stirring rod, and there is no mixing measure along the axial direction. The mixing method is single and the mixing effect is poor.

[0004] Therefore, we need to design a polyurea mixing device for offshore photovoltaic brackets to solve these problems. Summary of the invention

[0039] like Figure 1 As shown, a cover plate 12 is hingedly provided on the top of the outer tank body 1, which makes it easy to add raw materials into the inner tank body 2, and can also seal the inner tank body 2 during stirring to prevent debris from falling into the inner tank body 2.

[0040] The working process of this embodiment is as follows: during operation, the cover plate 12 on the top of the outer tank body 1 is opened, and then the raw materials required for the polyurea mixing are added into the inner tank body 2, and then the cover plate 12 is closed and the driving motor 11 is started. After the driving motor 11 is started, the driving pulley 29 is driven to rotate, and after the driving pulley 29 rotates, the driven pulley 28 is driven to rotate through the transmission belt 30, and after the driven pulley 28 rotates, the driving shaft 27 is driven to rotate, and after the driving shaft 27 rotates, the driving gear 16 drives the meshing driven gear 15 to rotate, and after the driven gear 15 rotates, the spline shaft 17 matched with the spline is driven to rotate, and after the spline shaft 17 rotates, it is rotated through the connected rotating shaft 6, and after the rotating shaft 6 rotates, it drives the stirring blade 7 to rotate the polyurea in the inner tank body 2 The mixed raw materials are stirred and mixed, and at the same time, when the driving shaft 27 rotates, the worm 26 is driven to rotate, and when the worm 26 rotates, the meshing worm wheel 20 is driven to rotate.

When the second push rod 24 rotates around the second installation axis 22, the lifting wheel 19 is driven to rotate. After the lifting wheel 19 rotates, the spline shaft 17 is driven to move axially along the support tube 14 through the lifting rod 18.

After the polyurea mixing is completed, the mixed polyurea can be discharged from the inner tank body 2 through the discharge pipe 8.
