[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0028] Example 1: As Figures 1-6 The technical solution shown is provided by the present utility model as follows: A compensator with good corrosion resistance and drainage is disclosed, which includes a water guide plate 5. The water guide plate 5 can guide and limit the discharged water flow. The compensator body 1 has fixed plates 2 at both ends and a fixed plate 2 between the two sets of fixed plates 2. The inside of the compensator body 1 is coated with a waterproof coating. The water guide plate 5 is fixedly connected to the outside of the compensator body 1. The upper surface of the water guide plate 5 is provided with water guide holes 6. The water guide plate 5 is located below the drain hole 4. The drain hole 4 is arranged around the center point of the compensator body 1. The position of the water guide hole 6 corresponds one-to-one with the position of the drain hole 4.

[0029] The threaded connection of the fixing screw 3 allows the fixing plate 2 to be stably assembled on the outside of the compensator body 1, making the assembly of the compensator body 1 more stable. Meanwhile, the inner side of the compensator body 1 is coated with an anti-corrosion coating, which protects the compensator body 1 from corrosion and extends its service life. A water guide plate 5 is provided on the outer side of the compensator body 1, positioned below the drain hole 4. When water flows out from the drain hole 4, the water guide plate 5 provides initial guidance, reducing the possibility of the discharged water adhering to the outer wall of the compensator body 1. Water guide holes 6 are formed on the upper surface of the water guide plate 5, their positions corresponding to the drain holes 4. The water guide holes 6 further limit the water flow position from the drain holes 4. The water guide holes 6 are recessed and have a small diameter; under the guidance of the water guide holes 6, the flow velocity increases, further reducing the possibility of water adhering to the outer wall of the compensator body 1 during discharge.

[0030] Example 2: Figures 1-6 The technical solution shown is provided by the present utility model as follows: A compensator with good corrosion resistance and drainage is disclosed, which has a drainage hole 4 through which water can flow outward: The lower side of the compensator body 1 is provided with a drainage hole 4, and the outer side of the compensator body 1 is provided with a sealing mechanism that can block the drainage hole 4. The sealing mechanism includes a baffle 7, which is nested on the outer side of the compensator body 1. A sealing ring 8 is fixedly connected to the inner side of the baffle 7, and a linkage block 10 is fixedly connected to the outer side of the baffle 7. The width of the baffle 7 is greater than the maximum value of the diameter of the drainage hole 4. The inner side of the sealing ring 8 is in contact with the outer wall of the compensator body 1, and the sealing ring 8 is made of elastic rubber.

[0031] The compensator body 1 has a drain hole 4 on its lower side. When there is water inside the compensator body 1, the water can flow out through the drain hole 4, thereby preventing water from being stored inside the compensator body 1 for a long time, which could lead to the growth of bacteria inside the compensator body 1. When it is necessary to drain the compensator body 1, the baffle 7 can be manually pulled upward. At this time, the baffle 7 does not block the drain hole 4, and the water can be discharged out through the drain hole 4.

[0032] Example 3: Figures 1-6 The technical solution shown is provided by the present invention as follows: a compensator with good corrosion resistance and drainage, which discloses a spring 11, which can drive the baffle 7 to reset, thereby improving the sealing performance of the compensator body 1; a limiting rod 9 is fixedly connected to the upper surface of the water guide plate 5, and a linkage block 10 is nested on the outer side of the limiting rod 9; a spring 11 is fixedly connected between the upper surface of the linkage block 10 and the upper end of the limiting rod 9; the linkage block 10 forms a sliding structure with the limiting rod 9 through the water guide plate 5; and the linkage block 10 forms an elastic structure with the limiting rod 9 through the spring 11; and the limiting rod 9 and the water guide hole 6 are misaligned on the water guide plate 5.

[0033] In the drainage state, the baffle 7 will drive the linkage block 10 to compress the spring 11, causing the spring 11 to undergo elastic deformation. When drainage is not required, the baffle 7 can be released. At this time, the spring 11 is not compressed. Driven by the elastic force of the spring 11, the linkage block 10 can move down along the limit rod 9 to reset, thereby further driving the baffle 7 to reset and block the drainage hole 4. At the same time, the sealing ring 8 can further improve the sealing performance of the baffle 7 in blocking the drainage hole 4, reducing the possibility of leakage in the compensator body 1.

[0034] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
