[0010] Furthermore, one end of the torsion spring is fixedly connected to the rotating shaft, and the other end of the torsion spring is fixedly connected to the fixing block.

[0011] Furthermore, mounting ears are fixedly connected to both sides of the support, and mounting ears are provided with mounting grooves for fixing the gas alarm to the support.

[0012] Furthermore, a first rubber pad is fixedly connected to the inner surface of the arc-shaped plate.

[0013] Furthermore, a lever plate extends outward from the top of the outer surface of the fastener.

[0014] Furthermore, a second rubber pad is fixedly connected to the inner surface of the gripper.

[0015] Furthermore, the gas alarm includes a sensor module and an alarm module. The sensor module is used to detect the gas concentration, and the alarm module is used to issue an audible and visual alarm signal when the gas concentration exceeds a preset threshold.

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0030] The installation process of existing gas pipeline safety detection devices is cumbersome, requires certain operating experience, increases the difficulty and time cost of installation, and is also prone to problems such as poor sealing effect or reduced detection sensitivity due to improper installation.

[0031] Furthermore, existing devices are difficult to adapt to situations where installation space is limited, such as narrow pipe spacing or the presence of other obstacles, leading to difficulties in installation and operation, or even making it impossible to proceed smoothly.

[0032] To address this, a safety testing device for gas pipelines was designed, which can be quickly and securely installed on gas pipelines, greatly simplifying the installation process and reducing installation difficulty and time costs.

[0033] like Figures 1-5 As shown, a safety detection device for gas pipelines includes an installation component 100, two fixing components 200 and a gas alarm 300. The installation component 100 includes a support 110, and an arc-shaped plate 120 is fixedly connected to the bottom of the support 110. Both ends of the arc-shaped plate 120 are provided with support blocks 130.

[0034] like Figure 3 , Figure 4 and Figure 6 As shown, two fasteners 200 are used to clamp onto the gas pipe. Each fastener 200 includes a gripper 210. Fixing blocks 220 are provided on both sides of the top of the gripper 210. The fixing blocks 220 are rotatably connected between two support blocks 130 via a rotating shaft 150. A torsion spring 160 is sleeved on the outer surface of the rotating shaft 150. One end of the torsion spring 160 is fixedly connected to the rotating shaft 150, and the other end is fixedly connected to the fixing block 220, providing the elastic force for closing the gripper 210. Under the action of the torsion spring 160, the two grippers 210 approach each other and can clamp onto the gas pipe. When disassembling the device, moving the two grippers 210 overcomes the elastic force of the torsion spring 160, allowing the two grippers 210 to open. Compared with existing technologies, this method is simpler to install, saves time and costs, and improves work efficiency.

[0035] like Figure 1 and Figure 2 As shown, the gas alarm 300 is fixedly connected to the top of the mounting bracket 100 and is used to detect gas leaks and issue alarm signals. The gas alarm 300 can be installed at the connection of the gas pipeline. The gas alarm 300 can monitor the gas concentration around the gas pipeline in real time and accurately. Once a gas leak is detected, the gas alarm 300 can immediately issue an audible and visual alarm signal to remind relevant personnel to take timely measures to prevent the accident from escalating.

[0036] like Figure 3 and Figure 4 As shown, a receiving groove 140 is formed between the two support blocks 130, and the fixing block 220 is located inside the receiving groove 140. The receiving groove 140 provides stable support and positioning for the fixing block 220, so that the fixing block 220 can rotate under the drive of the rotating shaft 150.

[0037] like Figure 3 As shown, mounting ears 170 are fixedly connected to both sides of the support 110. Mounting ears 170 are provided with mounting grooves 180 for fixing the gas alarm 300 to the support 110, which facilitates the installation and fixation of the gas alarm 300.

[0038] like Figure 5 As shown, a first rubber pad 190 is fixedly connected to the inner surface of the arc-shaped plate 120. The soft material of the first rubber pad 190 can fit tightly against the outer surface of the gas pipeline.

[0039] like Figure 6 As shown, a lever 230 extends outward from the top of the outer surface of the fixing member 200. This allows the operator to control the opening and closing of the gripper 210 by moving the lever 230 with their fingers or tools, facilitating the installation and fixation of the device.

[0040] like Figure 6 As shown, a second rubber pad 240 is fixedly connected to the inner surface of the gripper 210. The soft material of the second rubber pad 240 can prevent the gripper 210 from causing damage or scratches to its surface when clamping the gas pipeline.

[0041] The gas alarm 300 includes a sensor module and an alarm module. The sensor module detects the gas concentration, and the alarm module issues an audible and visual alarm signal when the gas concentration exceeds a preset threshold. The sensor module is a combustible gas sensor, which detects gas concentration by detecting changes in semiconductor resistance caused by gas adsorption. When the gas concentration exceeds the preset threshold, the alarm module immediately issues an audible and visual alarm signal to alert relevant personnel to take timely measures.

[0042] The device also includes a power module, which is electrically connected to the gas alarm 300 and is used to provide working power to the gas alarm 300. The power module can be powered by a battery or an external power source.

[0043] In use, the two jaws 210 are separated from each other and placed near the connection of the gas pipeline. Under the action of the torsion spring 160, the two jaws 210 come together and can be clamped onto the gas pipeline.

[0044] When disassembling the device, press the lever 230 inward, the fixing block 220 rotates on the outer surface of the rotating shaft 150, the two grippers 210 overcome the elastic force of the torsion spring 160, the two grippers 210 move away from each other and open, and the device can be removed from the gas pipeline.

[0045] It should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0046] 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.
