[0016] The specific content of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0017] like Figure 1 , Figure 2 and Figure 3As shown, this utility model provides a protective device for a steam pipe connection, including a first connecting pipe 1, a second connecting pipe 2, a first bolt 5, and a fixing plate 7. A first flange 11 and a second flange 21 are respectively fixed to the first connecting pipe 1 and the second connecting pipe 2. A sealing ring 3 is provided between the first flange 11 and the second flange 21. The first flange 11 and the second flange 21 are connected by the first bolt 5. Two first clamping blocks 71 are fixed on the fixing plate 7. A second clamping block 8 is provided at the bottom of the first clamping block 71. A second bolt is provided on the first clamping block 71 to connect with the second clamping block 8. 74. A protective sleeve 4 is fixed to the outer ring surface of the first flange 11. A fixing ring 22 that contacts the protective sleeve 4 is fixed to the side of the second flange 21 away from the first flange 11. The end of the first bolt 5 passes through the fixing ring 22. A cover 23 that covers the first bolt 5 is fixed to the fixing ring 22. A sliding ring 6 is fitted on the first connecting pipe 1. A connecting sleeve 61 that covers the large head of the first bolt 5 is fixed on the sliding ring 6. A fixing block 10 that abuts against the sliding ring 6 is fixed to the side of the first clamping block 71 and the second clamping block 8 on the first connecting pipe 1 that is close to the first flange 11. After inserting the second connecting pipe 2 into the first connecting pipe 1, the sealing ring 3 is placed between the first flange 11 and the second flange 21. Then, the first bolt is used to fix the first flange 11, the sealing ring 3, and the second flange 21 together. At this time, one end of the protective sleeve 4 abuts against the fixing ring 22, forming a sealed space. The sealing ring 3 is located in the sealed space, which can effectively prevent the sealing ring 3 from aging rapidly due to long-term exposure, thus avoiding the problem of decreased sealing performance. At the same time, the sealed space can also improve the sealing effect between the first flange 11 and the second flange 21. Even if the sealing ring 3 is damaged, the protective sleeve 4, together with the fixing ring 22, can still seal the gap between the first flange 11 and the second flange 21. The function of the first bolt 5 is as follows: the end of the first bolt 5 is located inside the cover 23. After the moving ring 6 is moved, the connecting tube 61 covers the large head of the first bolt 5. The cover 23 and the connecting tube 61 can effectively prevent the first bolt 5 from being exposed and prevent the first bolt 5 from rusting due to external factors. Then, after the first clamping block 71 and the second clamping block 8 are fixed together by the second bolt 74, the fixing block 10 can hold the moving ring 6 and fix the moving ring 6, preventing the moving ring 6 from moving at will. The side of the fixing block 10 that contacts the moving ring 6 is inclined. The inclined surfaces of the two fixing blocks 10 on the first clamping block 71 and the second clamping block 8 are opposite each other, so as to smoothly fix the first clamping block 71 and the second clamping block 8 on the first connecting tube 1 and hold the moving ring 6.

[0018] like Figure 1 , Figure 4 , Figure 5 and Figure 6As shown, the first clamping block 71 has a first connecting block 72 fixed on both sides, and the second clamping block 8 has a second connecting block 81 fixed on both sides. The second connecting block 81 is L-shaped. The first connecting block 72 is connected to the second connecting block 81 by a second bolt 74. A limit frame 73 is fixed on the top of the first connecting block 72. The second bolt 74 is located inside the limit frame 73. A cover 9 with its inner wall in contact with the outer wall of the limit frame 73 is provided above the first connecting block 72. A telescopic cylinder 91 with its telescopic end in contact with the top of the first connecting block 72 is fixed inside the cover 9. A movable plate 92 is fixed on one side of the cover 9. An opening for the movable plate 92 to pass through is provided on the horizontal surface inside the second connecting block 81. An insert plate 82 passes through the second connecting block 81. A through hole for the insert plate 82 to be inserted is provided on the movable plate 92. Both the first connecting block 72 and the second connecting block 81 have screw holes adapted to the second bolt 74, which can be used to fix the first connecting block 72 and the second connecting block 81 together. The side of the first connecting block 72 away from the first clamping block 71 is flush with the vertical surface of the inner side of the second connecting block 81. After the cover 9 is moved downward by the moving plate 92, the cover 9 can cover the limiting frame 73 and form a sealed space with the limiting frame 73, protecting the second bolt 74 and preventing it from being exposed and corroded. After the cover 9 moves downward, when the telescopic cylinder 91 contacts the top surface of the first connecting block 72, the telescopic cylinder 91 can be compressed as the cover 9 continues to move downward (the telescopic cylinder includes a cylinder body fixed to the top of the inner side of the cover 9, and a telescopic spring fixed inside the cylinder body, the other side of the telescopic spring...). The end is fixed to the rod body, and the rod body is slidably connected inside the cylinder. When the bottom end of the moving plate 92 passes through the opening and continues to move downward, the perforation on the moving plate 92 corresponds to the insertion plate 82, so that the insertion plate 82 can be inserted into the perforation, thus limiting the moving plate 92 and preventing it from moving arbitrarily. After the telescopic cylinder 91 is compressed, it will generate an upward thrust on the cover 9, so that the moving plate 92 can hold the insertion plate 82 upward and fix the insertion plate 82. The distance from the top to the bottom of the perforation on the moving plate 92 is slightly greater than the distance from the top to the bottom of the insertion plate 82, so that when the insertion plate 82 needs to be removed later, the staff can easily remove the insertion plate 82 by pulling the moving plate 92 downward. The moving plate 92 is provided with a pull-down opening for the staff to pass through, so that the staff can easily pull the moving plate 92 downward.

[0019] like Figure 6As shown, a spring 93 is fixed to the top inside the cover 9, and a protective frame 94 covering the second bolt 74 is fixed to the bottom end of the spring 93. The bottom of the protective frame 94 contacts the top of the first connecting block 72, and a rubber block 95, which contacts the second bolt 74, is fixed to the top inside the protective frame 94. When the cover 9 moves downward, causing the bottom of the protective frame 94 to contact the top of the first connecting block 72, the spring 93 is compressed as the cover 9 continues to move downward, making the contact between the protective frame 94 and the first connecting block 72 tighter, further sealing and protecting the second bolt 74. At the same time, the rubber block 95, after contacting the top of the second bolt 74, can press down on the second bolt 74, protecting and fixing it.

[0020] like Figure 1 , Figure 4 and Figure 6 As shown, a ring-shaped magnet 83 is embedded in the bottom surface of the inner side of the second connecting block 81. A rod 84 is connected to the second connecting block 81 via a connecting rope. Both the second connecting block 81 and the insert plate 82 have insertion holes for the rod 84. The insert plate 82 consists of a thicker plate and a thinner plate (e.g., ...). Figure 6 As shown in the diagram, the plate is inserted into the through hole on the insertable plate 92 and into the groove opened inside the opening of the second connecting block 81. The plate contacts the side of the second connecting block 81 away from the first clamping block 71. The insertion holes on the second connecting block 81 and the insert plate 82 correspond to each other, so the insertion rod 84 can be inserted into the insertion holes on the second connecting block 81 and the insert plate 82. The magnet 83 attracts the insertion rod 84. The insertion rod 84 is made of steel, which further increases the firmness of the connection between the insert plate 82 and the movable plate 92.

[0021] like Figure 1 and Figure 3 As shown, a rubber ring 41 is fixed to the side of the protective cylinder 4 near the fixing ring 22, and this rubber ring 41 contacts the fixing ring 22. The rubber ring 41 can increase the sealing of the contact area between the protective cylinder 4 and the fixing ring 22.

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, a rubber ring 62 is fixed to the end of the connecting cylinder 61 away from the moving ring 6, which contacts the first flange 11. The rubber ring 62 can increase the sealing of the contact area between the connecting cylinder 61 and the first flange 11.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
