[0002] It can monitor the gas concentration in the environment in real time and send alarm information to users or management platforms through wireless communication technology when a leak is detected, thereby realizing remote monitoring and timely response.

[0003] Existing gas leak alarm equipment is fixedly installed, which means that monitoring can only be completed when the gas leak spreads to the gas leak alarm equipment. When the gas leak alarm equipment is far away from the leakage point, a large amount of gas will leak before an early warning will be issued, which will lead to huge safety hazards. Summary of the Invention

[0004] The problem solved by the present invention is to provide a remote monitoring gas leak alarm device, which solves the technical problem that the existing gas leak alarm device is fixedly installed, that is, monitoring can only be completed when the gas leak spreads to the gas leak alarm device. When the gas leak alarm device is far away from the leakage point, a large amount of gas will leak before an early warning will be issued, which will lead to huge safety hazards.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A remote monitoring gas leak alarm device includes an electric slide rail, an electric slider and a monitoring mechanism, wherein the electric slide rail is slidably mounted with an electric slider, the electric slider is detachably mounted with a monitoring mechanism, the monitoring mechanism is wirelessly connected to the alarm, the monitoring mechanism includes a semicircular gear ring, and quarter-circular gear rings are rotatably mounted at both ends of the semicircular gear ring, the side walls of the semicircular gear ring and the quarter-circular gear ring are provided with annular rails, a slider is slidably mounted on the annular rail, a mounting plate is mounted on the slider, and the mounting plate is connected to a support seat, a slide is slidably mounted on the support seat, and a gas leak detector is mounted on the slide.

[0007] Preferably, a support arm is installed on the electric slider, and a mounting arm is installed on the semicircular gear ring.

[0008] Preferably, both the support arm and the mounting arm are provided with mounting grooves, and the bolts pass through the mounting grooves of the support arm and the mounting arm and are connected with nuts.

[0009] Preferably, both ends of the semicircular gear ring are provided with embedding grooves, the ends of the quarter-circular gear ring are provided with rotating blocks installed in the embedding grooves, and the first motors are embedded and installed at both ends of the semicircular gear ring, and the output end of the first motor is connected to the rotating block.

[0010] Preferably, a second motor is mounted on the mounting plate, and a rotating gear is mounted on the output end of the second motor, and the rotating gear is engaged with the semicircular gear ring and the quartercircular gear ring.

[0012] Preferably, a third motor is installed at the end of the support seat, and the output end of the third motor is located in the slide groove and connected to the threaded rod.

[0013] Preferably, the specific operating steps of the device are as follows:

[0014] Step 1: Set the electric slide rail flush with the gas pipeline, and use the first motor to drive the rotating block to rotate, thereby driving the quarter-circular gear ring to rotate on the semi-circular gear ring. Rotate the quarter-circular gear ring until the semi-circular gear ring is in an open state. At this time, cover the outside of the gas pipeline. Use the first motor to rotate the two quarter-circular gear rings to form a circular shape with the semi-circular gear ring. Fix the support arm and the mounting arm with bolts and nuts.

[0015] Step 2: The electric slider moves along the electric slide rail. At this time, the monitoring mechanism moves along the gas pipeline. The third motor drives the threaded rod to rotate, and then drives the threaded block connected by the thread to move in the slide groove to realize the translation of the slide. The position of the gas leak detector relative to the gas pipeline is adjusted first. During the movement, the second motor drives the rotating gear to rotate, and then drives the slider to rotate along the annular rail. That is, the gas leak detector rotates around the gas pipeline, and performs 360° rotation monitoring of the gas pipeline without dead angles. The monitoring results are transmitted to the alarm. Once a leak occurs, the alarm starts to alarm.

[0016] The beneficial effects of the present invention are as follows: the electric slider and the monitoring mechanism are detachably mounted, which facilitates the disassembly of the monitoring mechanism; at the same time, the first motor drives the rotating block to rotate, thereby driving the quarter-circular gear ring to rotate on the semi-circular gear ring; the quarter-circular gear ring is rotated until the semi-circular gear ring is in an open state, at which time the semi-circular gear ring is covered on the outside of gas pipelines of different specifications; at the same time, the third motor drives the threaded rod to rotate, thereby driving the threaded block connected by the thread to move in the slide groove, realizing the translation of the slide, adjusting the position of the gas leak detector relative to the gas pipeline, and facilitating the installation of the monitoring mechanism on the outside of different gas pipelines for use;

[0017] The second motor drives the rotating gear to rotate, and then drives the slider to rotate along the annular track. That is, the gas leak detector rotates around the gas pipeline, performing 360° rotation monitoring of the gas pipeline without blind spots to ensure comprehensive monitoring.
