Embodiment 1
[0030] A kind of anti-wind and rain excitation Haval sheath with continuous linear grooves 21 scattered on the surface of the Haval sheath, such as figure 1 , Figure 6-1 to Figure 6-5 As shown, there are 5 grooves on the outer surface of the Haval sheath resistant to wind and rain excitation, distributed in a continuous straight line on the Haval sheath, and the cross-sectional shape of the grooves is rectangular (see Figure 6-1 ) or trapezoidal (see Figure 6-2 ) or semicircle (see Figure 6-3 ) or semi-elliptical (see Figure 6-4 ) or triangle (see Figure 6-5 ) or other arbitrary polygons; the width K of the groove is 1-45mm, the depth S is 5-50% of the wall thickness d of the outer layer of the Haval sheath, and the distance between the grooves can be equal or not; There may be an outer boss on both sides of the groove, and the height H of the outer boss above the outer surface of the Haval sheath is 0.1-3 mm.

Embodiment 3
[0036] A kind of anti-wind and rain-excited vibration-resistant Haval sheath with dimples 3 scattered on the surface of the Haval sheath, such as image 3 , Figure 4 As shown, the outer surface of the anti-wind and rain-induced vibration Haval sheath is geometrically distributed with a number of pits, and the cross-sectional shape of the pits is rectangular (see Figure 7-1 ) or trapezoidal (see Figure 7-2 ) or semicircle (see Figure 7-3 ) or semi-elliptical (see Figure 7-4 ) or triangle (see Figure 7-5 ) or other arbitrary polygons; the width K of the pit is 1-45mm, the depth S is 5-50% of the wall thickness d of the outer layer of the Harvard sheath, and the spacing between the pits can be equal or not; There is an outer boss on both sides of the pit, and the height H of the outer boss above the outer surface of the Harvard sheath is 0.1-3mm.
[0037] As a change in the embodiment of the present invention, there may be no outer bosses on both sides of the pit (see ...
