Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipeline alarm technology, specifically to a gas pipeline audible and visual alarm device. Background Technology
[0002] Gas pipelines are tubular facilities used to transport various gases. They play a crucial role in industrial production, energy supply, construction, and daily life. Gas pipelines transport gases from gas sources to users through closed pipes. They are characterized by high transmission efficiency, low cost, and relatively controllable safety, and are the lifeblood system for energy and industrial gas transmission.
[0003] For some flammable and polluting gases, audible and visual alarm devices are generally used for monitoring. Pipeline leaks are usually concentrated at pipe joints, and audible and visual alarm devices are generally installed above the pipes for detection. When a gas leaks, the gas rises, and the audible and visual alarm device detects the gas leak and alerts workers to carry out maintenance through flashing lights and sounds. However, in environments with minor leaks and good ventilation, the gas will quickly dilute, thus failing to trigger the alarm. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] The technical problem this invention aims to solve is that in a well-ventilated environment with a small amount of leakage, the gas will be rapidly diluted, thus preventing the alarm from being triggered.
[0006] (II) Technical Solution
[0007] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a gas pipeline audible and visual alarm device, comprising two pipelines, a fixed plate at one end of each pipeline, the two fixed plates being fixedly connected by a bolt, an arc-shaped baffle plate 1 located above the fixed plate of each pipeline, and an arc-shaped baffle plate 2 located below the fixed plate of each pipeline, the arc-shaped baffle plate 1 and the arc-shaped baffle plate 2 being fixedly connected by a bolt, an audible and visual alarm device being provided on the arc-shaped baffle plate 1, the detection end of the audible and visual alarm device extending into the arc-shaped baffle plate 1.
[0008] As an improvement, both the first and second arc-shaped baffles are provided with arc-shaped sealing gaskets that fit into the pipe.
[0009] As an improvement, both the first and second arc-shaped shields are provided with extension plates arranged on both sides, and the second bolt fixes the first and second arc-shaped shields by fixing the two extension plates.
[0010] As an improvement, a sealing gasket is provided on the extension plate.
[0011] As an improvement, the radii of the first and second arc-shaped baffles are greater than the radius of the pipe.
[0012] As an improvement, the arc-shaped shield is provided with a support column that cooperates with the audible and visual alarm, and the audible and visual alarm is fixedly mounted on the support column.
[0013] (III) Beneficial Effects
[0014] The advantages of this utility model compared with the prior art are as follows:
[0015] (1) By setting up an arc-shaped baffle plate 1, an arc-shaped baffle plate 2 and an arc-shaped sealing gasket, the pipe connection can be sealed and the pipe connection can be kept sealed. By setting up an audible and visual alarm extending into the arc-shaped baffle plate 1, when a slight leak occurs at the connection, it can be detected immediately. The structure is simple, convenient and quick.
[0016] (2) When the gas density is greater than that of air, the gas will move downwards when a leak occurs. During installation, the arc-shaped baffle is installed at the bottom so that the sound and light alarm is also at the bottom, which can quickly detect whether a gas leak has occurred. It can adapt to gases of different densities and is highly practical. Attached Figure Description

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0023] As per the instructions Figures 1 to 3 As shown, a gas pipeline audible and visual alarm device includes two pipelines 1. One end of each pipeline 1 is provided with a fixed plate 2. The two fixed plates 2 are fixedly connected by bolts 1-3. An arc-shaped baffle 4 is provided above the pipeline 1 at the fixed plate 2, and an arc-shaped baffle 5 is provided below the pipeline 1 at the fixed plate 2. The arc-shaped baffle 4 and the arc-shaped baffle 5 are fixedly connected by bolts 2-6. An audible and visual alarm 7 is provided on the arc-shaped baffle 4. The detection end of the audible and visual alarm 7 extends into the arc-shaped baffle 4. The radii of the arc-shaped baffle 4 and the arc-shaped baffle 5 are larger than the radius of the pipeline 1.
[0024] As per the instructions Figures 2 to 4 As shown, both the first arc-shaped shielding plate 4 and the second arc-shaped shielding plate 5 are provided with arc-shaped sealing gaskets 8 that fit against the pipe 1. Both the first arc-shaped shielding plate 4 and the second arc-shaped shielding plate 5 are provided with extension plates 9 arranged on both sides. The second bolt 6 fixes the first arc-shaped shielding plate 4 and the second arc-shaped shielding plate 5 by fixing the two extension plates 9. The extension plates 9 are provided with sealing gaskets 10. The first arc-shaped shielding plate 4 is provided with a support column 11 that cooperates with the audible and visual alarm 7. The audible and visual alarm 7 is fixedly mounted on the support column 11.
[0025] In practical use, when the gas density is less than that of air, the arc-shaped baffle plate 14 is placed above the pipe 1, and the arc-shaped baffle plate 25 is placed below the pipe 1. The arc-shaped baffle plate 14 and the arc-shaped baffle plate 25 are then fixed with bolts 26. By setting the arc-shaped sealing gasket 8, firstly, air can be prevented from entering the sealed space formed by the arc-shaped baffle plate 14 and the arc-shaped baffle plate 25. At the same time, the arc-shaped sealing gasket 8 has a certain resistance, which can prevent the arc-shaped baffle plate 14 and the arc-shaped baffle plate 25 from rotating. When the pipe 1 leaks, the gas enters the sealed space formed by the arc-shaped baffle plate 14 and the arc-shaped baffle plate 25 from the pipe connection, and then floats up and is detected by the audible and visual alarm 7. The audible and visual alarm 7 sounds an alarm and notifies the workers to carry out maintenance.
[0026] When the gas density is greater than that of air, the arc-shaped baffle 4 is placed below the pipe and the arc-shaped baffle 5 is placed above the pipe. When the gas leaks, the gas enters the sealed space formed by the arc-shaped baffle 4 and the arc-shaped baffle 5 from the pipe connection. Then the gas sinks and is detected by the audible and visual alarm 7, which then alarms and notifies the workers to carry out maintenance.
