[0033] Example:

[0034] A bridge pier anti-pollution covering device, please refer to Figure 1-Figure 7, arranged on the pier a of the bridge, the above-mentioned bridge pier anti-pollution covering device includes a positioning structure 1, a connecting structure 2 and several protective components 3, wherein the positioning structure 1 is mainly used to be fixedly connected with the pier a, the positioning structure 1 includes a positioning plate 11 and a counterweight plate 12, the positioning plate 11 is fixed on the top of the pier a, and the weight of the positioning plate 11 is increased by the counterweight plate 12, thereby enhancing the stability of the positioning plate 11, and a positioning hole is provided on the positioning plate 11, and the inner wall of the positioning hole is provided with a threaded groove, and the inner wall of the threaded groove is threadedly connected with a self-positioning bolt, and the positioning plate 11 can be more stably fixed to the top of the pier a by inserting the self-positioning bolt into the inner wall of the positioning hole, thereby enhancing the stability of the protective device; in this patent, the connecting structure 2 is composed of several evenly distributed connecting pillars 21, preferably four connecting pillars 21, and the above-mentioned counterweight plate 1 2 is arranged inside the area surrounded by the four connecting pillars 21. In this way, even if the counterweight plate 12 and the positioning plate 11 become loose and separated, the counterweight plate 12 will not fall out of the restricted area surrounded by the four connecting pillars 21. The number of protective components 3 of the present patent is preferably four, and each protective component 3 includes a power mechanism 31 and a protective part 32. The protective part 32 is connected to the power mechanism 31, and the power mechanism 31 provides power to control the protective part 32 to retract or unfold. The above-mentioned bridge pier anti-pollution covering device also includes a control box 4. The power mechanism 31 is arranged in the control box 4, and an opening 41 is opened below the control box 4. The number of openings 41 is the same as the number of protective components 3.

[0035] In this embodiment, the protective portion 32 has two states: expanded and folded. In the expanded state, the protective portion 32 is released. When the protective portion 32 is maximally expanded, its lower end is flush with or exceeds the lower end of the pier a. In this way, the protective portions 31 of the four protective components 3 are fully expanded to form a protective area that wraps the entire side of the pier a. The above-mentioned protective area can prevent the erosion of the side of the pier during rainy days and when the river (or sea water) rises, and the protective effect is outstanding. In the folded state, the protective portion 32 is folded, and when the protective portion 32 is folded, the opening 41 is closed (each protective portion 32 closes the corresponding opening 41). The protective portion 32 is usually folded in non-rainy weather, and some insects or other small animals will also seek shelter in non-rainy weather. The control box 4 of the present patent is a very good shelter. Once it is selected as a shelter by animals, the animals will make certain modifications to the interior (such as piling up food for the winter), and the internal power machinery may be damaged (such as being stuck by food). The retracted protective part 32 of the present patent can effectively block the opening 41 connecting the control box 4 with the outside world, avoiding the occurrence of the above situation. In addition, it can also prevent dust and water vapor from entering the control box 4 through the opening 41 and causing adverse effects on the parts. In summary, the protective part 32 of the present patent has different functions on rainy days and non-rainy days. On rainy days, it can prevent water from eroding the pier a, and on non-rainy days, it can prevent small animals, dust or water vapor from entering the control box 4 and damaging the mechanical transmission structure, thereby extending the life of the structure.
