[0019] The technical solution of this utility model will be further described below through embodiments and in conjunction with the accompanying drawings.

[0020] Example:

[0021] This embodiment describes a modular power pole, such as... Figure 1 and Figure 2 As shown, it includes a base 1 and several towers 2. The base 1 is buried underground. The towers 2 are connected to the base 1 and to each other via flanges 3. The edge of the flange 3 end face is provided with several grooves. The grooves on two adjacent flanges 3 form an insertion hole. An upper protective cover 4 and a lower protective cover 5 are provided on the flange 3. The upper protective cover 4 and the lower protective cover 5 are fixed together by bolts 6. The end of the bolts 6 extends into the insertion hole.

[0022] like Figure 3 and Figure 4 As shown, the upper protective cover is annular and is composed of two first cover bodies spliced ​​together. Each first cover body includes a first arc-shaped top plate and a first arc-shaped side plate 43. The first arc-shaped side plate 43 is vertically positioned on the outer side of the lower end face of the first arc-shaped top plate. A protective layer 41 is provided on the lower end face of the first arc-shaped top plate. Several bolt grooves 42 are provided on the protective layer 41 corresponding to the bolt hole area of ​​the flange. Several fixing grooves 44 are provided on the lower end face of the first arc-shaped side plate 43. Several first bolt holes 45 penetrate the first arc-shaped side plate and connect to the fixing grooves. The first cover body is fitted onto the upper flange through the bolt grooves 42. The bolt grooves 42 serve both for positioning and for protecting the bolts, isolating them from the outside environment and preventing loosening and corrosion.

[0023] like Figure 5 and Figure 6 As shown, the lower protective cover is annular and is composed of two second covers joined together. Each second cover includes a first arc-shaped base plate 51 and a second arc-shaped side plate 52. The second arc-shaped side plate 52 is vertically positioned on the outer side of the upper surface of the first arc-shaped base plate 51. The upper surface of the second arc-shaped side plate 52 is provided with several fixing plates 53 that match the fixing grooves. The fixing plates 53 have through holes 54 corresponding to the first screw holes. The lower protective cover is inserted into the fixing groove of the upper protective cover via the fixing plates and then fixed with fixing bolts. After fixing, the upper and lower protective covers work together to isolate the flange and its bolts from the outside environment, thereby extending the lifespan of the flange and its bolts. In this embodiment, the two first covers and the two second covers are fixed together using clamps.

[0024] In addition, in this embodiment, a wire groove for guiding and embedding can be provided on the flange end face. The wire groove connects the groove and the detection component inside the tower, and hollow bolts are used as fixing bolts. In this way, the wires of the detection component inside the tower can be led out of the tower outside through the hollow inside the tower, the wire groove, the socket and the hollow bolt in sequence, which is convenient for debugging the detection component inside the tower or connecting an external power supply and communication module.

[0025] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
