Description

Technical Field

[0001] This utility model relates to the field of gas detection and alarm technology, specifically a flame-retardant and explosion-proof combustible gas detector and alarm. Background Technology

[0002] Combustible gas refers to substances that can be ignited and exist in a gaseous state at normal temperature and pressure. The detection principle of combustible gas detectors is mainly based on the sensor's sensitive response to specific gases, converting the gas concentration into an electrical signal to trigger an alarm.

[0003] Due to the instability of combustible gases, combustible gas detectors are prone to explosion during the detection process. Common combustible gas detectors are inconvenient to adjust after installation, and if the installation location is close to the gas impact zone, explosion is likely to occur, affecting the safety of use.

[0004] There is an urgent need for a flame-retardant and explosion-proof combustible gas detector and alarm to address the technical deficiencies mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a flame-retardant and explosion-proof combustible gas detector and alarm to solve the problem of easy combustion and explosion caused by airflow impact mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a flame-retardant and explosion-proof combustible gas detector and alarm, comprising a support slide rail and a gas detection sensor. An adjusting screw is movably connected inside the support slide rail, and a screw sleeve is installed outside the adjusting screw. A mounting base is fixedly connected to the right side of the screw sleeve, and an explosion-proof box is installed on the right side of the mounting base. The gas detection sensor is installed inside the explosion-proof box. A mounting plate is fixedly connected to the left side of the support slide rail. A drive motor is installed at the bottom end of the support slide rail, and a motor controller is installed on the right side of the drive motor. A detection controller is installed inside the explosion-proof box. A remote alarm and an alarm light are respectively installed on the top of the explosion-proof box. A detection port is provided at the bottom end of the explosion-proof box. A connecting wire is fixedly connected to the motor controller, and the connecting wire is connected to the detection controller.

[0007] As a further technical solution of this utility model, the motor controller is electrically connected to the drive motor, and the gas detection sensor is electrically connected to the detection controller.

[0008] As a further technical solution of this utility model, the detection controller includes a detection module, a control module and an alarm module.

[0009] As a further technical solution of this utility model, both the remote alarm and the alarm light are connected to the detection controller.

[0010] As a further technical solution of this utility model, the explosion-proof box is made of aluminum alloy, and an explosion-proof surface is installed on the inner wall of the explosion-proof box.

[0011] As a further technical solution of this utility model, a limit stop bar is movably connected to the left side of the front end of the mounting base, a mounting slot is provided inside the mounting base, and a mounting block is fixedly connected to the left side of the explosion-proof box.

[0012] As a further technical solution of this utility model, the mounting block is embedded inside the mounting slot and limited by a limiting stop bar.

[0013] As a further technical solution of this utility model, the mounting plate is provided in three sets, and the mounting plate is provided with threaded holes inside.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the flame-retardant and explosion-proof combustible gas detector and alarm not only realizes the function of explosion-proof by adjusting the position and the function of easy and quick disassembly and assembly, but also realizes the function of preventing flame leakage.

[0015] (1) The detection equipment is installed in the area to be detected by setting up a support slide rail, adjusting screw, screw sleeve, drive motor, motor controller, gas detection sensor and detection controller. During the detection process, once the gas detection sensor detects that the gas concentration exceeds the standard, the remote alarm and alarm light can be alarmed in time. The controller controls the alarm to be alarmed, which is existing technology, so it will not be described in detail. In order to avoid the gas detection sensor being impacted by the gas, once the gas detection sensor detects that the concentration exceeds the standard, the detection controller can control the drive motor through the motor controller. The drive motor drives the adjusting screw to rotate, which can move the gas detection sensor upward and away from the gas. This structure adjusts the detection position by detecting the gas density to avoid the occurrence of combustion and explosion.

[0016] (2) By setting up an explosion-proof box, mounting base, mounting block, limit bar and mounting slot, the explosion-proof box can be quickly disassembled from the mounting base. When installing the explosion-proof box, align the mounting block with the mounting slot and insert it. Then rotate the limit bar to press it against the front end of the mounting block to limit it. When disassembling, rotate the limit bar to move it away and then move the mounting block out from the inside of the mounting slot. This structure realizes the function of easy and quick disassembly and assembly.

[0017] (3) By setting up an explosion-proof box, alarm light, remote alarm and explosion-proof surface, the explosion-proof box is made of high-strength aluminum alloy. In the event of an explosion of the gas detection sensor, the explosion-proof box can withstand the internal explosion pressure and prevent the flame from leaking out. The explosion-proof surface inside the explosion-proof box enhances the explosion-proof effect. The alarm light and remote alarm on the explosion-proof box can enhance the alarm effect. This structure realizes the function of preventing flame leakage and facilitating timely alarm, and improves the safety of the device. Attached Figure Description

A mounting base 14 is fixedly connected to the right side of the screw sleeve 3. An explosion-proof box 9 is installed on the right side of the mounting base 14. The gas detection sensor 10 is installed inside the explosion-proof box 9. A mounting plate 4 is fixedly connected to the left side of the support slide rail 1. A drive motor 5 is installed at the bottom of the support slide rail 1. A motor controller 6 is installed on the right side of the drive motor 5. A detection controller 11 is installed inside the explosion-proof box 9. A remote alarm 12 and an alarm light 13 are respectively installed on the top of the explosion-proof box 9. A detection port 8 is provided at the bottom of the explosion-proof box 9. A connecting wire 7 is fixedly connected to the motor controller 6 and connected to the detection controller 11.

[0025] The motor controller 6 is electrically connected to the drive motor 5, the gas detection sensor 10 is electrically connected to the detection controller 11, and the detection controller 11 includes a detection module, a control module and an alarm module. The remote alarm 12 and the alarm light 13 are both connected to the detection controller 11.

[0026] Specifically, such as Figure 1 and Figure 4 As shown, during the detection process, once the gas detection sensor 10 detects that the gas concentration exceeds the standard, the remote alarm 12 and the alarm light 13 can sound an alarm in time. The controller controlling the alarm is existing technology, so it will not be described in detail. In order to avoid the gas detection sensor 10 being impacted by the gas, once the gas detection sensor 10 detects that the concentration exceeds the standard, the detection controller 11 can control the drive motor 5 through the motor controller 6. The drive motor 5 drives the adjusting screw 2 to rotate, which can move the gas detection sensor 10 upward and away from the gas.

[0027] A limit stop bar 17 is movably connected to the left side of the front end of the mounting base 14. The mounting base 14 is provided with a mounting slot 18. The left side of the explosion-proof box 9 is fixedly connected with a mounting block 15. The mounting block 15 is embedded in the mounting slot 18 and is limited by the limit stop bar 17. The mounting plate 4 is provided with three sets. The mounting plate 4 is provided with threaded holes.

[0028] Specifically, such as Figure 1 and Figure 3 As shown, the explosion-proof box 9 can be quickly installed and removed from the mounting base 14. When installing the explosion-proof box 9, align the mounting block 15 with the mounting slot 18 and insert it. Then rotate the limiting rod 17 to press it against the front end of the mounting block 15 to limit its movement. When disassembling, rotate the limiting rod 17 to move it away and then remove the mounting block 15 from the mounting slot 18.

[0029] The explosion-proof box 9 is made of aluminum alloy, and the inner wall of the explosion-proof box 9 is equipped with an explosion-proof surface 16.

[0030] Specifically, such as Figure 1 and Figure 2 As shown, the explosion-proof box 9 is made of high-strength aluminum alloy. In the event of an explosion of the gas detection sensor 10, the explosion-proof box 9 can withstand the internal explosion pressure and prevent the flame from leaking out. The explosion-proof surface 16 inside the explosion-proof box 9 enhances the explosion-proof effect. The alarm light 13 and remote alarm 12 on the explosion-proof box 9 can enhance the alarm effect.

[0031] Working principle: The detection equipment needs to be installed in the detection area first. The mounting plate 4 on the support slide rail 1 can be used to fix the equipment with bolts. During the detection process, once the gas detection sensor 10 detects that the gas concentration exceeds the standard, the remote alarm 12 and alarm light 13 can sound an alarm in time. The controller controlling the alarm is existing technology, so it will not be described in detail. In order to prevent the gas detection sensor 10 from being impacted by the gas, once the gas detection sensor 10 detects that the concentration exceeds the standard, the detection controller 11 can control the drive motor 5 through the motor controller 6. The drive motor 5 drives the adjusting screw 2 to rotate, which moves the gas detection sensor 10 upward and away from it. The explosion-proof enclosure 9 is made of high-strength aluminum alloy. In the event of an explosion of the gas detection sensor 10, the enclosure 9 is strong enough to withstand the internal explosion pressure and prevent the flame from escaping. The explosion-proof surface 16 inside the enclosure 9 enhances the explosion-proof effect. The enclosure 9 can be quickly installed and removed from the mounting base 14. When installing the enclosure 9, align the mounting block 15 with the mounting slot 18 and insert it. Then rotate the limiting rod 17 to press it against the front end of the mounting block 15 to limit its movement. When disassembling, rotate the limiting rod 17 to move it away and then remove the mounting block 15 from the mounting slot 18. This structure enables quick and easy installation and disassembly.
