Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0030] Reference Figures 1-5 A safety cover for chemical pipelines includes a pipeline 1, a bottom shell 2 and a top shell 3. A flange and bolts are installed at one end of the pipeline 1. The bottom shell 2 is located at the bottom of the pipeline 1. The top shell 3 is installed at the top of the bottom shell 2. A protective shell is installed on the top of the top shell 3. A clamping assembly 4 is installed inside the top shell 3. An auxiliary assembly 5 is installed inside the bottom shell 2.
[0031] The clamping assembly 4 includes a movable plate 401, a movable block 402, a groove 403, a rack 404, a gear 405, a telescopic rod 406, an outer plate 407, and an arc plate 408. The movable plate 401 is installed inside the top of the top shell 3, and its outer wall is slidably connected to the inner wall of the top shell 3. The movable block 402 is fixedly connected to the outer wall of the movable plate 401. The groove 403 is formed inside the top shell 3, and its outer wall is slidably connected to the inner wall of the groove 403. The movable plate 401 can drive the movable block 402 to slide inside the groove 403. The movable block 402 and the groove 403 cooperate to ensure the stability of the movable plate 401 during movement. The rack 404 is fixedly connected to the outer wall of the movable plate 401, penetrating the movable plate 401 and extending to its exterior. The outer wall of the rack 404 is slidably connected to the inner wall of the movable plate 401 through which it is penetrated. When the movable plate 401 moves, the rack 404 can move inside the movable plate 401. A gear 405 is disposed outside the rack 404 and meshes with it. A telescopic rod 406 is fixedly connected to the gear 405. At the top, the tip of the telescopic rod 406 penetrates the top of the inner wall of the top shell 3 and extends to the top of the top shell 3. The outer wall of the telescopic rod 406 is rotatably connected to the inner wall of the top shell 3 through which it is penetrated. The telescopic rod 406 can be moved by rotation, causing the telescopic rod 406 to drive the gear 405 to rotate. When the gear 405 rotates, the rack 404 will pull the moving plate 401 to move under the action of the gear 405. The outer plate 407 is fixedly connected to the outer wall of the output end of the telescopic rod 406. The arc plate 408 is installed on the top of the top shell 3, and the bottom of the arc plate 408 penetrates the top shell 3 and extends to the inner wall of the top shell 3. The outer plate 407 extends into the arc plate 408 from the side away from the telescopic rod 406 and is rotatably connected to the inner wall of the arc plate 408. The output end of the telescopic rod 406 can be moved so that the output end of the telescopic rod 406 drives the arc plate 408 to rise and fall through the outer plate 407. The telescopic rod 406 can drive the outer plate 407 to rotate inside the arc plate 408. The bottom of the arc plate 408 is provided with a toothed groove, and the gear 405 is engaged with the toothed groove. During the movement of the arc plate 408, the gear 405 can be limited by the toothed groove.
[0032] By installing a movable plate 401 and an arc plate 408 inside the top shell 3, and by rotating the telescopic rod 406, the telescopic rod 406 drives the gear 405 to rotate. At this time, the rack 404 will pull the movable plate 401 to move under the action of the gear 405 until the outer wall of the movable plate 401 contacts the outer wall of the bolt on the flange surface. Then, by pressing down the telescopic rod 406, the arc plate 408 will descend and engage with the gear 405 through the tooth groove, thus completing the limiting of the gear 405. At this time, the movable plate 401 will strengthen the connection strength between the pipes 1, preventing gaps from appearing at the connection during long-term use of the pipes 1, which could lead to leakage of chemicals inside the pipes 1. This solves the problem that the existing protective cover cannot improve the sealing effect of the pipe 1 joint connection.
[0033] Auxiliary component 5 includes a second movable plate 501, a spring 502, a second movable block 503, a second groove 504, and a slot 505. The second movable plate 501 is installed inside the bottom shell 2, and its outer wall is slidably connected to the inner wall of the bottom shell 2, allowing it to move inside the bottom shell 2. The spring 502 is fixedly connected to the inner wall of the bottom shell 2, and the side of the spring 502 away from the bottom shell 2 is fixedly connected to the outer wall of the second movable plate 501. The presence of the spring 502 allows the second movable plate 501 to be pulled back to its original position. The second movable block 503 is fixedly connected to the outer wall of the second movable plate 501. The second groove 504 is formed inside the bottom shell 2. The outer wall of the second movable block 503 is slidably connected to the inner wall of the second groove 504. The second movable plate 501 can drive the second movable block 503 to move inside the second groove 504. The cooperation between the second movable block 503 and the second groove 504 can ensure the stability of the second movable plate 501 during movement. The slot 505 is formed on the outer wall of the second movable plate 501. The slot 505 is engaged with the outer wall of the first movable plate 401. When the first movable plate 401 moves, it will be engaged inside the slot 505 and push the second movable plate 501 to move through the slot 505.
[0034] By setting up a second movable plate 501 and a slot 505, when the first movable plate 401 moves, it will be inserted into the slot 505. At the same time, the slot 505 will drive the second movable plate 501 to move until the outer walls of both the second movable plate 501 and the first movable plate 401 are in contact with the bolts on the outer wall of the flange. The presence of the second movable plate 501 can assist the first movable plate 401 and further enhance the sealing strength at the connection of the pipe 1.
[0035] The working principle of this safety cover for chemical pipelines is as follows: Two pipelines 1 are connected by bolts and flanges. Then, by moving the bottom shell 2, the pipeline 1 is secured to the top of the bottom shell 2. The top shell 3 is then installed by sliding. Bolts are then used to fix the bottom shell 2 and the top shell 3 together. At this point, the first moving plate 401 and the second moving plate 501 are located at the top and bottom of the pipeline 1, respectively. The protective cover is then removed, and the telescopic rod 406 is pulled up, causing the telescopic rod 406 to move the arc plate 408 and separate it from the gear 405. The telescopic rod 406 is then rotated, causing it to drive the gear. Rotation 405 drives the first movable plate 401 to move via rack 404, causing the bottom of the outer wall of the first movable plate 401 to engage with the inside of the slot 505. The slot 505 then pushes the second movable plate 501 to move until the outer walls of both the first and second movable plates 401 are in contact with the bolts on the outside of the flange. Then, the telescopic rod 406 is pressed down, causing the telescopic rod 406 to drive the arc plate 408 to descend. The telescopic rod 406 engages with the gear 405 via the tooth groove, thus limiting the position of the gear 405 and ensuring the clamping effect of the first movable plate 401 and the second movable plate 501 at the connection of pipe 1.
[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
