[0003] However, existing safety covers for chemical pipelines are often installed and fixed with bolts, which is time-consuming and laborious, increases installation time, reduces the convenience of installation, and makes them inconvenient to use. In addition, existing safety covers for chemical pipelines often do not have a tight sealing structure, and when they are not tightly closed, they can easily cause gas leakage, which can endanger human health. Therefore, there is an urgent need for a new type of safety cover for chemical pipelines to solve the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide a safety cover for chemical pipelines, so as to solve the problem that the existing safety covers for chemical pipelines mentioned in the background art are often installed and fixed by fixing bolts, which is time-consuming and laborious to install, and the existing safety covers for chemical pipelines often do not have a tight sealing structure, which can easily cause gas leakage when they are not tightly closed.

Detailed Implementation

[0022] 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.

[0023] Please see Figure 1-6 This utility model provides an embodiment of a safety cover for chemical pipelines, comprising a cover body 1, protrusions 2, a second cover body 3, protrusions 4, a hinge 5, and a fixing structure 6. Sealing rings 12 are fixedly connected to the inner walls of the left and right ends of the cover body 1, and sealing rings 32 are fixedly connected to the inner walls of the left and right ends of the cover body 3. The cover body 1 is rotatably connected to the cover body 3 via the hinge 5. Two protrusions 2 are fixedly connected to the bottom of the cover body 1, and the protrusions 2 engage with the cover body 3. Two protrusions 4 are fixedly connected to the top of the cover body 3, and the protrusions 4 engage with the cover body 1. The fixing structure 6 includes a fixing plate 61, and two fixing plates 61 are fixedly connected to the front side of the cover body 1. Plate 1 61 and two fixing plates 2 62 are fixedly connected to the front side of the cover 2 3. The fixing plates 2 62 are rotatably connected to the rotating rod 63. The top of the rotating rod 63 is fixedly connected to the threaded rod 64. The threaded rod 64 is threadedly connected to the handle 65. The bottom of the handle 65 is fixedly connected to the limiting seat 66. The bottom of the limiting seat 66 is snapped into the fixing plate 1 61. The top of the cover 1 is fixedly connected to the gas leak detector 7. The device can be quickly installed on the pipeline through the fixing structure 6. The installation is convenient and quick, without the need for fixing bolts, and is easy to use. The gas leak detector 7 detects the inside of the cover 1 and the cover 2 3. When there is a gas leak, an alarm is sounded.

[0024] Furthermore, the first protrusion 2 includes a sealing ring 21, and the second protrusion 4 includes a sealing ring 41. Both the first sealing ring 21 and the second sealing ring 41 are composed of two C-shaped rubber rings, and the surfaces of the two C-shaped rubber rings are provided with serrated patterns. The two C-shaped rubber rings mesh with each other. When the two sealing rings 21 and 41 mesh with each other, the joint between the first protrusion 2 and the second protrusion 4 is sealed, and the sealing performance is improved by the serrated patterns.

[0025] Furthermore, both protrusion 1 2 and protrusion 2 4 are C-shaped. A sealing ring 1 21 is fixedly connected to the outer wall of protrusion 1 2, and a sealing ring 2 41 is fixedly connected to the outer wall of protrusion 2 4. The joint between cover 1 1 and cover 2 3 is reinforced by protrusion 1 2 and protrusion 2 4, so that cover 1 1 and cover 2 3 fit together more tightly.

[0026] Furthermore, the bottom of the cover 1 has two slots 11, and the inner wall of the slot 11 is fixedly connected to a sealing ring 41. The slot 11 engages with the protrusion 4. When the cover 1 is placed on the cover 3, the protrusion 4 engages in the slot 11. The top of the cover 3 has two slots 31, and the inner wall of the slot 31 is fixedly connected to a sealing ring 21. The slot 31 engages with the protrusion 2. When the cover 1 is placed on the cover 3, the protrusion 2 engages in the slot 31.

[0027] Furthermore, the grip 65 is a hexagonal grip with an anti-slip coating on its surface. The anti-slip coating prevents slippage when rotating the grip 65, and the hexagonal grip is easier to hold. Rotating the grip 65 causes the grip 65 to move the limit seat 66 downward.

[0028] Furthermore, the limiting seat 66 is T-shaped, with a round hole in the middle, and the diameter of the round hole is larger than the diameter of the threaded rod 64. The handle 65 drives the limiting seat 66 to move downward, so that the limiting seat 66 abuts against the top of the fixing plate 61, thereby fixing the position of the cover 1.

[0029] Working principle:

[0030] In use, when the device needs to be installed at a pipe connection, place cover 23 at the bottom of the pipe, and rotate cover 1 through hinge 5 so that cover 1 covers cover 23. The sealing rings 12 and 32 at both ends seal the joints between cover 1 and cover 23 and the pipe. Simultaneously, protrusion 2 engages with slot 31, and protrusion 4 engages with slot 11. The two sealing rings 21 and 41 mesh with each other, thus sealing the joint between protrusions 2 and 4. The placement of protrusions 2 and 4 ensures a tighter fit between cover 1 and cover 23, improving the sealing performance of the device. The airtight seal prevents gas leakage and improves safety during use. When it is necessary to fix the position of the cover 1, rotate the rotating rod 63 from the horizontal direction to the vertical direction, so that the threaded rod 64 rotates into the fixing plate 61. Rotate the handle 65 so that the handle 65 drives the limiting seat 66 to move downward, so that the limiting seat 66 abuts against the top of the fixing plate 61, thereby fixing the position of the cover 1. The device can be quickly installed on the pipeline through the fixing structure 6, and the installation is convenient and quick without fixing bolts, making it easy to use. The gas leak detector 7 detects the inside of the cover 1 and the cover 3, and an alarm is sounded when there is a gas leak.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
