The extension surface of the left half sleeve 41 toward the right half sleeve 42 is in contact with the extension surface of the right half sleeve 42 toward the left half sleeve 41. A fixing block 5 is arranged on the extension surface of the left half sleeve 41 toward the right half sleeve 42, and a groove 6 is arranged on the extension surface of the right half sleeve 42 toward the fixing block 5. A compression spring 7 is vertically arranged in the groove 6, and a stopper 8 is arranged on the upper end of the compression spring 7. When the fixing block 5 is inserted into the groove 6, the lower surface of the fixing block 5 is in contact with the upper surface of the stopper, so that the protective sleeve 4 is installed outside the fixing tube 2.

[0032] Preferably, the protective cover 4 is divided into an upper cover and a lower cover in the vertical direction, the bottom end of the upper cover is fixedly connected to the top end of the lower cover, the bottom end of the lower cover is connected to the upper surface of the base 1, and the fixing tube is located in the lower cover, and the inner wall of the upper cover is in contact with the tower foot 3.

[0033] Preferably, the cross section of the tower foot 3 in the horizontal direction is circular, and the inner wall of the lower half sleeve is a vertically arranged cylinder, and the bottom radius of the cylinder is equal to the radius of the circle, so that the inner wall of the upper half sleeve fits the outer wall of the tower foot 3. The purpose is to make the inner wall of the protective cover 4 fit the outer wall of the tower foot 3, so as to avoid that after the protective cover 4 is installed on the tower base 1, there is a gap between the protective cover 4 and the tower foot 3, causing rainwater or other chemical media to fall into the protective cover 4 through the gap, and affect the bolts on the fixing cover inside the protective cover 4.

[0034] Preferably, the inner wall of the lower half sleeve is a vertically arranged truncated cone, and the upper bottom radius of the truncated cone is equal to the bottom radius of the cylinder, and the lower bottom radius of the truncated cone is equal to or greater than the outer diameter of the fixed cylinder 2. Among them, since the iron tower foot 3 is provided with a fixed sleeve, when the protective sleeve 4 is installed outside the fixed sleeve and the iron tower foot 3, the protective sleeve 4 is a protective sleeve 4 with a small upper part and a large lower part, so that the inner wall of the protective sleeve 4 can fit the outer wall of the iron tower foot 3 while surrounding the fixed sleeve and the iron tower foot 3.

[0035] In one embodiment, the cross-section of the outer wall of the protective cover 4 in the horizontal direction may include a square, a circle, a rectangle, etc., which are not limited here. In this embodiment, the cross-section of the outer wall of the protective cover 4 in the horizontal direction is a circle.

[0036] Preferably, a slide groove is provided on the outer wall of the right half sleeve 42, and the slide groove is vertically arranged and connected to the side of the groove 6. A slider 9 is provided on the stop block 8, and the lower surface of the fixed block 5 is in contact with the upper surface of the slider 9.

[0038] In this embodiment, the specific working principle is:

[0039] After the power tower base 1 is set, bolts are used to fix the tower foot 3 in the fixing tube 2, and then the protective cover 4 corresponding to the tower foot 3 is taken out, and the right half cover 42 and the left half cover 41 are respectively located on both sides of the tower foot 3. At this time, the slider 9 and the compression spring 7 of the right half cover 42 are in the initial position, and the slider 9 on the right half cover 42 is moved downward along the slide groove. When the slider 9 moves downward, the slider 9 applies pressure to the compression spring 7 through the stopper 8 to press the compression spring 7 downward, and then the corresponding fixing block 5 on the left half cover 41 is inserted into the groove 6. When the fixing block 5 is located in the groove 6, the slider 9 is moved upward, and the fixing block 5 is fixed to the groove 6. The limiting portion 51 on the upper surface of the block 5 is inserted into the slot 61, so that the fixed block 5 is completely embedded in the groove 6, so that the left half sleeve 41 and the right half sleeve 42 are in close contact, that is, there is no gap between the corresponding extended surfaces of the left half sleeve 41 and the right half sleeve 42. At the same time, since the fixed block 5 is located above the compression spring 7, the slider 9 and the compression spring 7 are located below the initial position at this time, the compression spring 7 will apply upward pressure to the fixed block 5, so that the fixed block 5 is fixed in the groove 6, and the fixed block 5 is embedded in the groove 6 through the limiting portion 51 and the slot 61, so that the fixed block 5 will not shake left and right, resulting in a gap between the corresponding extended surfaces of the left half sleeve 41 and the right half sleeve 42.

[0040] When the protective cover 4 needs to be removed, it is only necessary to move the slider 9 on the right half cover 42 downward along the slide groove, and move the fixing block 5 downward so that the limiting portion 51 on the upper surface of the fixing block 5 is removed from the slot 61, and then the fixing block 5 is removed from the groove 6, so that the left half cover 41 and the right half cover 42 can be separated. This operation is relatively simple and convenient for staff to use.
