Description

Technical Field

[0001] This utility model relates to the field of safety cover technology, specifically to a triggering alarm mechanism and a safety cover for chemical pipelines. Background Technology

[0002] Chemical pipelines are used to transport toxic, harmful, and corrosive media. They are mainly used in industries such as pharmaceuticals, metallurgy, environmental protection, water supply and drainage, and petroleum. When transporting gases, chemical pipelines use gaskets to seal and protect the connections. However, after a period of use, the gaskets age and are prone to gas leakage. The gaskets are not effective in protecting the leaked harmful gases, which can easily spread and pollute the environment.

[0003] Currently, patent CN222209979U discloses a safety cover for chemical pipelines, including a chemical pipeline body, an upper protective cover, and a lower protective cover. The upper and lower protective covers are fitted onto the outer surface of the chemical pipeline body. A warning mechanism is provided on the top of the upper protective cover, and a sealing mechanism is provided on the inner side of the upper and lower protective covers. The warning mechanism includes a support cylinder, a fixing plate, a connecting rod, a rubber sheet, a spring, and a protrusion. The support cylinder is welded to the top of the upper protective cover, and the fixing plate is welded to the inner surface of the support cylinder. When excessive harmful gas leaks between the upper and lower protective covers, the air pressure between them increases. This air pressure pushes the rubber sheet, which, through the connecting rod, pushes the protrusion upwards, allowing the protrusion to pop out. This facilitates observation of the harmful gas leak by workers, enabling timely maintenance of the chemical pipeline body and making the safety cover more convenient to use.

[0004] However, in the aforementioned patent, the rubber sheet and the support cylinder are slidably connected, which makes the seal between the rubber sheet and the support cylinder a dynamic seal. Long-term use will make the sealing performance of the device insufficient, thus making it possible for harmful gases to leak. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model proposes a triggering alarm mechanism that has high sealing performance and is not prone to leakage.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a triggering alarm mechanism, comprising a sealing tube, wherein a triggering mechanism is disposed inside the sealing tube, and an alarm is threadedly connected to one end of the sealing tube;

[0007] The alarm includes a rotating block that is threadedly connected to a sealing pipe, and a clearance groove is provided on the upper surface of the rotating block. A battery is installed in the clearance groove. A fixing cover is threadedly connected to the upper surface of the rotating block. A buzzer is fixedly connected to the upper surface of the fixing cover. A cavity is provided on the lower surface of the rotating block, and a touch switch is installed in the cavity.

[0008] The triggering mechanism includes a threaded cover, and a bellows is fixedly connected to one side wall of the threaded cover. A baffle is fixedly connected to one end of the bellows, and a protrusion is fixedly connected to one side wall of the baffle. The protrusion is located below the touch switch. A connection hole connecting the bellows and the protective cover is opened on one side wall of the threaded cover.

[0009] Preferably, a spring is provided inside the bellows, with one end of the spring fixedly connected to the threaded cap and the other end of the spring fixedly connected to the baffle.

[0010] Preferably, a second soft pad is provided between the rotating block and the sealing tube.

[0011] Preferably, a second soft pad is provided between the rotating block and the sealing tube.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figures 1 to 4 An alarm triggering mechanism includes a sealing tube 2, a triggering mechanism is provided inside the sealing tube 2, and an alarm is threadedly connected to one end of the sealing tube 2;

[0023] The alarm includes a rotating block 3 that is threadedly connected to a sealing tube 2. The upper surface of the rotating block 3 has a clearance groove, in which a battery 4 is installed. A fixing cover 5 is threadedly connected to the upper surface of the rotating block 3. A buzzer 6 is fixedly connected to the upper surface of the fixing cover 5. The battery 4 can power the buzzer 6. The lower surface of the rotating block 3 has a cavity, in which a touch switch 7 is installed. The touch switch 7 can control the buzzer 6 to start. When the touch switch 7 is touched, the touch switch 7 can activate the buzzer 6, causing the buzzer 6 to emit an alarm sound.

[0024] The triggering mechanism includes a threaded cap 8, with a bellows 9 fixedly connected to one side wall of the threaded cap 8. A baffle 10 is fixedly connected to one end of the bellows 9, and a protrusion 11 is fixedly connected to one side wall of the baffle 10. The protrusion 11 is located below the touch switch 7. A connecting hole 12 is provided on one side wall of the threaded cap 8, connecting the bellows 9 and the protective cover 1. By setting up the triggering mechanism composed of the bellows 9 and the protrusion 11, when the pipeline leaks, the leaked gas enters the protective cover 1. The gas entering the protective cover 1 can increase the gas pressure inside the protective cover 1, which in turn causes the gas inside the protective cover 1 to enter the bellows 9 through the connecting hole 12. This increases the gas in the bellows 9, causing the bellows 9 to collide. The collided bellows 9 can drive the baffle 10 and the protrusion 11 to move, causing the protrusion 11 to push the touch switch 7, which in turn turns on the buzzer 6. This triggering mechanism has good sealing performance. As long as the bellows 9 is not damaged, the triggering mechanism will generally not leak.

[0025] As can be seen from the above structure, by setting an alarm, one end of the sealing tube 2 can be sealed, and a triggering mechanism is set inside the sealing tube 2. The triggering mechanism can trigger the alarm to provide an alert. The device is designed to seal the sealing tube 2 with the alarm. Even if the triggering mechanism leaks, the sealing tube 2 and the alarm can be sealed again, thereby improving the sealing performance of the device and reducing the possibility of harmful gas leakage.

[0026] See Figure 3 and Figure 4 A spring 13 is installed inside the bellows 9, and one end of the spring 13 is fixedly connected to the threaded cover 8, while the other end of the spring 13 is fixedly connected to the baffle 10. By installing the spring 13, the bellows 9 can be pulled so that the bellows 9 will not expand when the air pressure inside the bellows 9 is not at a certain level.

[0027] See Figure 3 and Figure 4 A second soft pad 15 is provided between the rotating block 3 and the sealing tube 2; by providing the second soft pad 15, the airtightness between the rotating block 3 and the sealing tube 2 can be improved.

[0028] See Figure 3 and Figure 4 An elastic membrane 16 is fixedly connected to the inner wall of the cavity; by setting the elastic membrane 16, the touch switch 7 can be sealed.

[0029] See Figures 1 to 4 A safety cover for a chemical pipeline includes a protective cover 1, a triggering alarm mechanism as described above is provided on one side of the protective cover 1, and the sealing tube 2 of the triggering alarm mechanism is connected to the protective cover 1, and the threaded cover 8 is threadedly connected to the protective cover 1.

[0030] See Figure 3 and Figure 4 A first soft pad 14 is provided between the threaded cover 8 and the protective cover 1; by providing the first soft pad 14, the airtightness between the threaded cover 8 and the protective cover 1 can be improved.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
