DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0030] The following describes an embodiment of the utility model based on its overall structure.

[0031] A wind power tower rain cover, such as Figure 1-Figure 5As shown, it includes a rain cover body, a ground base 3, bolts 4, nuts 5 and a tower body 6, wherein the tower body 6 is fixedly mounted on the ground base 3 by bolts 4 and nuts 5, and the rain cover body is mounted on the outer wall of the tower body 6;

[0032] Specifically, the rain shield body is composed of a first shield 1 and a second shield 2;

[0033] Among them, the first protective cover 1 and the second protective cover 2 are sleeved on the outer wall of the tower body 6, and the first protective cover 1 and the second protective cover 2 are both provided with a first connecting groove 7 corresponding to the bolt 4 at the bottom, so that the first protective cover 1 and the second protective cover 2 can be connected to the bolt 4 through the first connecting groove 7, so that the bolt 4 will limit the position of the first protective cover 1 and the second protective cover 2, and ensure the fixity of the lateral position of the first protective cover 1 and the second protective cover 2 after installation. At the same time, the first protective cover 1 and the second protective cover 2 are both provided with a second connecting groove 8 corresponding to the nut 5 at the bottom, so that the first protective cover 1 and the second protective cover 2 can be sleeved on the outside of the nut 5 through the second connecting groove 8, so that after the first protective cover 1 and the second protective cover 2 are installed, the bolt 4 and the nut 5 will be shielded, and the bolt 4 and the nut 5 will be protected, thereby preventing a large amount of rainwater from directly contacting the bolt 4 and the nut 5 during the rainy season, causing serious corrosion to the bolt 4 and the nut 5;

[0034] The first protective cover 1 and the second protective cover 2 are both equipped with a plurality of upper handles 12. The upper handles 12 are arranged to facilitate hoisting the first protective cover 1 and the second protective cover 2 or moving the first protective cover 1 and the second protective cover 2 by manpower.

[0035] Furthermore, a first connecting plate 9 is installed at the end of the first shield 1, and a corresponding first connecting groove 7 and a second connecting groove 8 are opened at the bottom of the first connecting plate 9, so that the first connecting plate 9 is also slidably connected with the bolt 4 and the nut 5, and at the same time, a second connecting plate 10 is installed at the end of the second shield 2, which is in contact with the first connecting plate 9, and the end of the second connecting plate 10 is in contact with the end of the first shield 1. Because the second connecting plate 10 is located above the first connecting plate 9, after the first shield 1 and the second shield 2 are installed, the first connecting plate 9 will be squeezed by the second connecting plate 10, thereby reducing the gap between the first shield 1 and the second shield 2, and increasing the probability of rainwater passing through between the first shield 1 and the second shield 2 during rainfall;

[0036] Furthermore, a second connecting groove 8 is provided at the bottom of the second connecting plate 10, so that the bolt 4 can enter the second connecting plate 10 through the second connecting groove 8, so that the installation positions of the first connecting plate 9 and the second connecting plate 10 are restricted, thereby ensuring the fixity of the installation positions of the first connecting plate 9 and the second connecting plate 10;

[0037] It should be noted that sealing strips 11 that are in contact with the outer wall of the tower body 6 are installed on the inner walls of the first protective cover 1 and the second protective cover 2, so that after the first protective cover 1 and the second protective cover 2 are installed, the sealing strips 11 will increase the sealing between the first protective cover 1 and the second protective cover 2 and the tower body 6, and effectively reduce the probability of rainwater passing through between the first protective cover 1 and the second protective cover 2 and the tower body 6.

[0038] See also Figure 1 one Figure 3 The first protective cover 1 and the second protective cover 2 are both designed in a semicircular ring shape, so that the first protective cover 1 and the second protective cover 2 are in a circular ring shape after being assembled, and the bottom of the first protective cover 1 and the second protective cover 2 are in contact with the top of the bottom end of the tower body 6. Since the diameter of the first protective cover 1 and the second protective cover 2 is larger than the diameter of the bottom of the tower body 6, it is ensured that the first protective cover 1 and the second protective cover 2 will protect all the bolts 4 and nuts 5;

[0039] Furthermore, the thickness and length of the first connecting plate 9 installed at the end of the first shield 1 and the second connecting plate 10 installed at the end of the second shield 2 are the same, and the thickness of the first connecting plate 9 is half of the thickness of the first shield 1, so that after the first connecting plate 9 and the second connecting plate 10 are attached to each other, the thickness of the first connecting plate 9 and the second connecting plate 10 together is the same as the thickness of the first shield 1 and the second shield 2, so that the setting of the first connecting plate 9 and the second connecting plate 10 will not have too much influence on the appearance of the first shield 1 and the second shield 2.

[0040] See also Figure 2 The diameter of the first connecting groove 7 is larger than the diameter of the bolt 4, and the diameter of the second connecting groove 8 is larger than the diameter of the nut 5, ensuring that the bolt 4 can smoothly enter the first connecting groove 7 and the nut 5 can smoothly enter the second connecting groove 8. Because the top surface of the second connecting groove 8 is in contact with the top surface of the nut 5, the top of the nut 5 will be restricted by the second connecting groove 8, thereby reducing the probability of the nut 5 loosening and improving the fixity of the position of the nut 5 after installation.

[0041] See also Figure 2 and Figure 3 A plurality of sealing strips 11 are installed at equal intervals on the inner walls of the first protective cover 1 and the second protective cover 2. The plurality of sealing strips 11 will further improve the sealing between the first protective cover 1 and the second protective cover 2 and the tower body 6. At the same time, because the top of the topmost sealing strip 11 among the plurality of sealing strips 11 is located at a higher level than the top of the first protective cover 1 and the second protective cover 2, the topmost sealing strip 11 will block and guide rainwater, further preventing rainwater from entering between the first protective cover 1 and the second protective cover 2 and the tower body 6.

[0042] See also Figure 1 , Figure 3 and Figure 4The outer walls of the first protective cover 1 and the second protective cover 2 are both rotatably mounted with a connecting block 13, and the outer wall of the connecting block 13 is also mounted with a side handle 16. The side handle 16 is arranged to make it easier for the user to pull the connecting block 13. At the same time, a protrusion 14 is mounted on the outer wall of the end of the connecting block 13, and a positioning block 15 corresponding to the protrusion 14 is mounted on the outer wall of the ground base 3, so that the positioning block 15 can limit the connecting block 13 through the protrusion 14, so that the longitudinal position of the first protective cover 1 and the second protective cover 2 is restricted and fixed, further ensuring the fixed position of the first protective cover 1 and the second protective cover 2 after installation;

[0043] Furthermore, because the bottom corners of the positioning block 15 are designed with arc-shaped rounded corners, the connecting block 13 can smoothly bring the protrusion 14 to the bottom of the positioning block 15 when it rotates, and the bottom of the positioning block 15 and the top of the protrusion 14 are only in contact with each other. Moreover, because magnetically attractive magnets are provided in the bottom of the positioning block 15 and the top of the protrusion 14, the fitting stability between the bottom of the positioning block 15 and the top of the protrusion 14 is further increased.

[0044] See also Figure 5 A water diversion groove 17 is provided at the top of the connection position between the first connecting plate 9 and the first protective cover 1. When rainwater enters the gap between the first connecting plate 9 and the first protective cover 1, it will fall into the water diversion groove 17. At the same time, because the water diversion groove 17 is inclined downward from the first protective cover 1, the water diversion groove 17 will guide the rainwater out from between the first connecting plate 9 and the first protective cover 1, further reducing the probability of rainwater corroding the bolts 4 and the nuts 5.

[0045] The working principle of the utility model is as follows: when the rain cover needs to be installed, the first protective cover 1 is first moved to a state where it fits the tower body 6, and then the first protective cover 1 is pushed downward until its bottom is in contact with the top of the ground base 3. At this time, the bolts 4 and nuts 5 enter the first connecting grooves 7 and the second connecting grooves 8 at the bottom of the first protective cover 1, so that the first protective cover 1 at this time is restricted by the bolts 4 and the nuts 5. Then, the second protective cover 2 is installed in the same way as above. When the bottom of the second protective cover 2 is in contact with the top of the ground base 3, the bottom end of the second connecting plate 10 at the end of the second protective cover 2 is in contact with the top of the first connecting plate 9. At the same time, the outer wall of the second shield 2 will be in contact with the outer wall of the end of the first shield 1, and finally the connecting block 13 is rotated to make the protrusion 14 rotate to the bottom of the positioning block 15. At this time, the top surface of the protrusion 14 will be in contact with the bottom surface of the positioning block 15, so that the connection between the first shield 1 and the second shield 2 and the ground base 3 is fixed. Because the top of the second connecting groove 8 will be in contact with the top of the nut 5, when the height of the first shield 1 and the second shield 2 is fixed, the position of the nut 5 will also be restricted, so that the nut 5 cannot move upward, thereby reducing the probability of the accident of the nut 5 moving upward and causing the connection to be loose;

[0046] When it rains, the first protective cover 1 and the second protective cover 2 will block the rain, thereby reducing the corrosion of the bolts 4 and the nuts 5 by the rain.
