[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example: Figures 1-5 As shown, this utility model provides a safety cover for chemical pipelines, including a lower cover body 1. Two symmetrically distributed first fixing plates 11 are fixedly installed on one side of the lower cover body 1. A guide rod 12 is fixedly installed on one side of the first fixing plate 11. A second fixing plate 13 is rotatably sleeved on the outside of the guide rod 12. An upper cover body 14 is fixedly installed on the side of the second fixing plate 13 near the lower cover body 1. A first fixing block 15 is fixedly installed on the side of the upper cover body 14 away from the second fixing plate 13. An insertion rod 16 is provided at the bottom end of the first fixing block 15. A second fixing block 2 is fixedly installed on the side of the lower cover body 1 near the first fixing block 15. The interior of the fixed block 2 is a cavity. The top of the second fixed block 2 has a slot 21 that works with the insertion rod 16. A movable block 22 is slidably attached to one side of the second fixed block 2. A movable rod 23 is fixedly installed on one side of the movable block 22. The bottom of the insertion rod 16 has a fixed groove 24 that works with the movable rod 23. Connecting plates 25 are fixedly installed on both sides of the movable block 22. A first spring 26 is fixedly installed on the side of the connecting plate 25 away from the movable rod 23. The first spring 26 is fixedly connected to the inner wall of the second fixed block 2. The movable block 22 is pulled by a U-shaped block (not labeled in the figure).

[0019] The interior of the first fixing block 15 is a cavity. A connecting rod 3 is slidably mounted in the middle of the first fixing block 15. A disc 31 is fixedly installed at the bottom end of the connecting rod 3. The diameter of the disc 31 is larger than the diameter of the insertion rod 16. A second spring 32 is fixedly installed at the top end of the disc 31. The second spring 32 is fixedly connected to the lower surface of the inner wall of the first fixing block 15. A handle 33 is rotatably connected to the top of the connecting rod 3. The insertion rod 16 is fixedly connected to the disc 31 and slidably connected to the first fixing block 15.

[0020] Two symmetrically distributed vertical plates 4 are fixedly installed on the side of the second fixed block 2 away from the moving rod 23. A locking block 41 is slidably engaged on the inner side of the vertical plate 4. An L-shaped plate 42 is fixedly installed on the side of the locking block 41 away from the vertical plate 4. A slot 40 for cooperating with the L-shaped plate 42 is opened through the top of the moving block 22. By setting the L-shaped plate 42, when the insertion rod 16 is inserted into the slot 21 on the second fixed block 2, the moving block 22 is pulled outward by the U-shaped block. The movement of the moving block 22 drives the connecting plate 25 and the moving rod 23 to move, so that the moving rod 23 moves away from the fixing slot 24 on the insertion rod 16. As the connecting plate 25 moves, the first spring 26 contracts. When the slot 40 on the moving block 22 corresponds to the L-shaped plate 42, the L-shaped plate 42 moves downward and is locked into the corresponding slot 40. As the L-shaped plate 42 moves downward, the locking block 41 moves downward in the vertical plate 4, thereby preventing the first spring 26 from driving the moving rod 23 to rebound back, affecting the insertion rod 16 into the slot 21. After the insertion rod 16 is inserted into the slot 21, the L-shaped plate 42 is pulled upward, and the first spring 26 loses resistance, causing the moving rod 23 to be locked into the fixing slot 24, thereby realizing the installation of the upper cover 14 and the lower cover 1 together.

[0021] A liquid drain trough 5 is provided through the bottom of the lower cover 1. A liquid hopper 51 is fixedly installed on the lower surface of the lower cover 1. The bottom of the liquid hopper 51 is trapezoidal. A liquid drain pipe 52 is fixedly installed at the bottom of the liquid hopper 51. A capacitive liquid level sensor 53 is provided on the outside of the liquid drain pipe 52. The capacitive liquid level sensor 53 is wirelessly connected to the alarm of the monitoring terminal. A liquid collection tank 54 is threadedly connected to the bottom of the liquid drain pipe 52. By setting up the liquid drain trough 5, if a liquid leak occurs at the connection of the chemical pipeline, the liquid will be directly... The liquid flows from the lower trough 5 on the lower cover 1 into the lower hopper 51. Under the action of the slope of the lower hopper 51, the liquid flows from the lower pipe 52 into the collection tank 54, thus collecting the liquid and preventing the liquid from corroding the outside of the pipe. When the capacitive liquid level sensor 53 reaches the set value, it transmits a signal to the alarm. The trapezoidal operator needs to process the liquid in the collection tank 54 to prevent too much liquid from being collected in the collection tank 54 and coming into contact with the outer wall of the pipe.

[0022] The first spring 26 has a telescopic rod 6 inside. One end of the telescopic rod 6 is fixedly connected to the connecting plate 25, and the other end of the telescopic rod 6 is fixedly connected to the inner wall of the second fixing block 2. By setting the telescopic rod 6, the first spring 26 is more stable when it contracts.

[0023] Contact plates 7 are fixedly installed on both sides of the liquid collection pipe 52. By setting the contact plates 7, when the processed liquid collection tank 54 is installed on the liquid collection pipe 52, the liquid collection tank 54 contacts the contact plate 7, indicating that the liquid collection tank 54 is completely installed on the liquid collection pipe 52. This makes it clearer where the liquid collection tank 54 needs to be rotated, and no further rotation is required.

[0024] The movable rod 23 is externally fixed with several evenly distributed ring-shaped stabilizing plates 8. The bottom of the insertion rod 16 is provided with a through groove 81 that works with the stabilizing plates 8. By setting the stabilizing plates 8 and the through groove 81, the movable rod 23, which is stuck in the fixed groove 24, is more tightly and stably secured.

[0025] The liquid receiving tank 54 is made of polytetrafluoroethylene plastic, which has good corrosion resistance and can withstand corrosive components that may be present in chemical liquids or gases. In actual use, the liquid receiving tank 54 can also be made of other materials, such as polypropylene (PP).

[0026] Working principle: In actual use, when installing the safety cover at the connection of the chemical pipeline, first open the upper cover 14 and the lower cover 1, then make the semi-circular groove on the lower cover 1 fit against the outer wall of the pipeline, rotate the upper cover 14 so that the first fixing block 15 on the upper cover 14 fits against the second fixing block 2 on the lower cover 1, and insert the rod 16 into the slot 21. Before inserting the rod 16 into the slot 21, turn the handle 33. During the rotation of the handle 33, the connecting rod 3 is slowly pulled upward. The movement of the connecting rod 3 causes the disc 31 and the rod 16 to move upward. The second spring 32 contracts. When the handle 33 changes from horizontal to vertical, it means that the rod 16 has completely retracted into the first fixing block 15. At the same time, the moving rod 23 is prevented from rebounding by the L-shaped plate 42.

[0027] When the first fixing block 15 and the second fixing block 2 are in contact, it also means that the upper cover 14 and the lower cover 1 are in contact. Then, the handle 33 is rotated in the opposite direction. Under the action of the second spring 32, the disc 31 and the insertion rod 16 rebound. When the vertical handle 33 becomes the horizontal handle 33, it means that the insertion rod 16 is completely inserted into the slot 21. Then, the L-shaped plate 42 is pulled upward. The first spring 26 loses its resistance and causes the moving block 22 and the moving rod 23 to rebound, so that the moving rod 23 is inserted into the fixing groove 24, thereby realizing the installation between the upper cover 14 and the lower cover 1.

[0028] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
