Abstract
Description
Technical Field
[0001] This utility model relates to the field of safety covers for chemical pipelines, and more specifically, to a safety cover for chemical pipelines. Background Technology
[0002] Chemical pipelines, as crucial and indispensable facilities in chemical production, bear the important mission of transporting various fluid materials. Their role extends throughout the entire complex production process, from raw material input, through intermediate product flow, to the final product output. Chemical pipelines are primarily circular. This is because circular pipelines have unique advantages in terms of mechanical properties; they can evenly distribute the pressure generated by the internal fluid, resulting in relatively balanced stress throughout the pipeline and effectively reducing the risk of pipeline rupture due to localized stress concentration.
[0003] Existing chemical pipeline connections are more prone to leakage than other locations. Structurally, these connections are where two or more pipes meet, making them far more complex than the pipes themselves. They have numerous sealing surfaces, making sealing difficult. Once the sealing material ages, wears out, or is improperly installed, gaps easily form, creating a breeding ground for leaks. The consequences of leaks are significant. First, they lead to material loss. Whether it's expensive raw materials or valuable finished products, leaks cause direct economic losses and increase production costs. Furthermore, if the leaked material is corrosive, it can damage surrounding equipment and buildings, shortening their lifespan and increasing maintenance costs and replacement frequency.
[0004] How to design a safety cover for chemical pipelines to improve these problems has become an urgent issue for those skilled in the art. Utility Model Content
[0005] To overcome the above deficiencies, this utility model provides a safety cover for chemical pipelines, which aims to improve the problems mentioned in the background.
[0006] This utility model is implemented as follows:
[0007] This utility model provides a safety cover for a chemical pipeline, including an upper protective cover, a lower protective cover, and a pipeline. The upper and lower protective covers are fitted onto the outer side wall of the pipeline. An alarm component is provided on the top of the upper protective cover. The alarm component includes a housing fixedly connected to the top of the upper protective cover, a cover plate fixedly connected to the top of the housing, a circuit box and a battery on the inner side of the housing, and a buzzer fixedly connected to the inner side wall of the housing. The battery and the buzzer are located on both sides of the circuit box. A protrusion is provided on the inner side wall of the upper protective cover. Two conductive rods are fixedly connected inside the protrusion. A trigger diaphragm is fixedly connected to the bottom of the protrusion, and a contact plate is fixedly connected to the top of the trigger diaphragm. The contact plate is located between the trigger diaphragm and the protrusion.
[0008] Preferably, the top end of the conductive rod is located inside the housing.
[0009] Preferably, the bottom end of the conductive rod is located between the trigger diaphragm and the protrusion, and the contact piece is disposed in a non-contact manner with the conductive rod.
[0010] Preferably, one of the conductive rods is electrically connected to the battery, and the other conductive rod is electrically connected to the buzzer.
[0011] Preferably, the upper protective cover is provided with a sealing plate, the sealing plate is arc-shaped, the upper protective cover is provided with a mounting plate, the mounting plate has mounting holes, the inner side wall of the upper protective cover is provided with a pressure plate, and the inner side of the upper protective cover is provided with a sealing component.
[0012] Preferably, the sealing assembly includes a sealing ring and a sealing sheet. The sealing ring is semi-annular and integrally formed with the sealing sheet. A sealing sleeve is provided on the sealing ring and fits snugly against the sealing plate. The sealing sheet is located below the pressure plate.
[0013] Preferably, the mounting plate is provided with bolts, the upper protective cover and the lower protective cover are fixedly connected by bolts, and a set of sealing components is provided between the upper protective cover and the lower protective cover.
[0014] The beneficial effects of this utility model are: by bolting the upper and lower protective covers onto the outside of the sealing assembly to wrap the connection of the pipe, when the chemical liquid leaks from the connection, the chemical liquid cannot leak into the external environment due to the presence of this chemical pipeline safety cover, thus preventing environmental pollution.
[0015] The pressure from a continuous leak of chemical liquid acts on a trigger diaphragm, causing the contact plate to come into contact with two conductive rods, which in turn triggers a buzzer to sound an alarm, alerting staff that a liquid leak has occurred at the pipe connection point. This allows staff to detect the leak promptly and prevent more serious safety accidents. Attached Figure Description

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.
[0024] Example, refer to Figures 1-5A safety cover for a chemical pipeline includes an upper protective cover 1, a lower protective cover 2, and a pipeline 3. The upper protective cover 1 and the lower protective cover 2 are fitted onto the outer side wall of the pipeline 3. An alarm component is provided on the top of the upper protective cover 1. The alarm component includes a housing 11 fixedly connected to the top of the upper protective cover 1. A cover plate is fixedly connected to the top of the housing 11. A circuit box 12 and a battery 13 are provided on the inner side of the housing 11. A buzzer 14 is fixedly connected to the inner side wall of the housing 11. The battery 13 and the buzzer 14 are located on both sides of the circuit box 12. A protrusion 15 is provided on the inner side wall of the upper protective cover 1. Two conductive rods 16 are fixedly connected inside the protrusion 15. A trigger diaphragm 17 is fixedly connected to the bottom of the protrusion 15. A contact piece 18 is fixedly connected to the top of the trigger diaphragm 17. The contact piece 18 is located between the trigger diaphragm 17 and the protrusion 15. The top of the conductive rod 16 is located inside the housing 11.
[0025] The bottom end of the conductive rod 16 is located between the trigger diaphragm 17 and the protrusion 15. The contact piece 18 is non-contact with the conductive rod 16. One of the conductive rods 16 is electrically connected to the battery 13, and the other conductive rod 16 is electrically connected to the buzzer 14. A sealing plate 21 is provided on the upper protective cover 1. The sealing plate 21 is arc-shaped. A mounting plate 22 is provided on the upper protective cover 1. The mounting plate 22 has mounting holes. A pressure plate 23 is provided on the inner wall of the upper protective cover 1. A sealing assembly is provided, which includes a sealing ring 24 and a sealing sheet 25. The sealing ring 24 is semi-circular and the sealing ring 24 and the sealing sheet 25 are integrally formed.

A set of sealing assemblies is provided between the upper protective cover 1 and the lower protective cover 2.
[0026] The working principle of this chemical pipeline safety cover is as follows: A set of sealing components is fitted onto the outer wall of the pipeline 3, and then the upper protective cover 1 and the lower protective cover 2 are fitted onto the outside of the sealing components by bolts 27 to wrap the connection of the pipeline 3, thus completing the installation of the chemical pipeline safety cover. Through the compression of the sealing components by the upper protective cover 1 and the lower protective cover 2, the connection of the pipeline 3 is isolated from the external environment. When chemical liquid leaks from the connection, the chemical liquid cannot leak into the external environment due to the installation of the chemical pipeline safety cover, thus preventing environmental pollution.
[0027] When the chemical liquid continues to leak, the chemical liquid exerts a squeezing force on the trigger diaphragm 17. The trigger diaphragm 17 deforms under the squeezing force, causing the contact piece 18 to move towards the conductive rod 16. When the contact piece 18 contacts the two conductive rods 16, the battery 13 and the buzzer 14 are connected in a circuit, which supplies power to the buzzer 14 and causes the buzzer 14 to sound an alarm, reminding the staff that there is a liquid leak at the pipeline connection point. This allows the staff to detect the leak in time and prevent more serious safety accidents.
