Description

Technical Field

[0001] This utility model relates to a gas safety monitoring device for chemical enterprises, belonging to the field of gas safety monitoring technology. Background Technology

[0002] Currently, chemical plants typically equip their premises with gas monitoring devices to monitor gas leaks in real time and prevent gas leaks from affecting safe production.

[0003] The gas monitoring device mainly consists of an alarm controller and a gas detector. The gas detector is installed at locations in the chemical gas production process where gas is prone to leakage. The gas detector converts the gas concentration detected by the sensor into an electrical signal, which is transmitted to the alarm controller via cable. The higher the gas concentration, the stronger the electrical signal. When the gas concentration reaches or exceeds the alarm point set by the alarm controller, the alarm will issue an alarm signal.

[0004] Traditional gas monitoring equipment typically suffers from the following technical problems: The monitoring range is fixed, resulting in dead zones and blind spots: Once installed, traditional equipment has a fixed monitoring direction and density. For complex chemical sites (such as multi-level platforms, dense pipelines and tanks), monitoring blind spots can easily form, making it impossible to effectively cover all potential leak points.

[0005] Response delay and insufficient sensitivity: Traditional gas monitoring equipment mostly relies on the natural diffusion of gases for detection. For gases at long distances or in the early stages of a leak with low concentrations, the diffusion process is slow, leading to alarm delays and making it easy to miss the best time for response.

[0006] Poor flexibility and insufficient adaptability: When the production process changes, the equipment layout is adjusted, or a certain area needs to be monitored temporarily, traditional fixed equipment is difficult to redeploy quickly and requires complex reinstallation, which is time-consuming and labor-intensive.

[0007] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0008] This invention addresses the shortcomings of the prior art by providing a gas safety monitoring device for chemical enterprises. It enables flexible, three-dimensional, multi-degree-of-freedom monitoring, greatly eliminating monitoring blind spots. It adopts active guided sampling, resulting in faster response speed and higher monitoring sensitivity.

[0009] To solve the above technical problems, the present invention adopts the following technical solution: A gas safety monitoring device for chemical enterprises includes a gas monitoring base, which is fixed to the side of a slider, and the slider is slidably mounted on a linear guide rail. Inside the gas monitoring base is a fixing plate, on one side of which a PID sensor is installed, and on the other side a turbine fan is installed. A straight suction pipe is installed on the side of the gas monitoring base away from the slider, and a swing seat is hinged to the end of the straight suction pipe away from the gas monitoring base. A gas collection hood is provided at the bottom of the swing seat, and a flexible tube for connecting the straight suction pipe and the gas collection hood is provided inside the swing seat.

[0010] Furthermore, the turbine fan is located between the fixed plate and the slider.

[0011] Furthermore, the periphery of the fixing plate is provided with multiple air intake holes, which are connected to the air intake end of the turbine fan.

[0012] Furthermore, the bottom of the gas monitoring base is provided with an exhaust port for connecting to the exhaust end of the turbine fan.

[0013] Furthermore, the intake straight tube is fixedly connected to the gas monitoring seat via a conical seat, and the center line of the intake straight tube is set directly opposite the PID sensor.

[0014] Furthermore, the top of the swing base is hinged to one end of the electric telescopic rod, and the other end of the electric telescopic rod is hinged to the support.

[0015] Furthermore, the support is fixed to the gas monitoring base.

[0016] Furthermore, an alarm is fixedly installed on the gas monitoring base, and both the PID sensor and the alarm are connected to the control unit.

[0017] Furthermore, the intake straight pipe is arranged in a horizontal direction.

[0018] Furthermore, the linear slide rail is arranged in the vertical direction.

[0019] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages: Through the design of sliders and linear guide rails, the entire monitoring equipment can be raised and lowered vertically and self-locked, which can cope with leakage sources at different heights. By driving the swing seat with an electric telescopic rod to change the pitch angle of the gas collection hood, it can achieve monitoring of specific areas. Through the combination of height and angle adjustment, a monitoring point can cover a three-dimensional fan-shaped area, eliminating monitoring blind spots.

[0020] The built-in turbine fan provides powerful and stable suction, which can actively and quickly capture the gas in the target area through the gas collection hood and blow it directly to the sensor's sensitive element in the form of a concentrated airflow. This precise gas delivery mode greatly shortens the transmission path and time of the gas sample, making the monitoring process more flexible, more adaptable, and improving the response speed.

[0021] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description

[0025] like Figure 1 and Figure 2 As shown in the diagram, this utility model provides a gas safety monitoring device for chemical enterprises, including a gas monitoring base 3, which is fixedly connected to the side of a slider 1. The slider 1 is slidably mounted on a vertically arranged linear slide rail 2. The slider 1 has a self-locking function, and the height of the gas monitoring base 3 can be adjusted by moving the slider 1 along the linear slide rail 2.

[0026] The gas monitoring base 3 has a fixed plate 4 inside. A PID sensor 6 is installed on one side of the fixed plate 4, and a turbine fan 7 is installed on the other side of the fixed plate 4. The turbine fan 7 is located between the fixed plate 4 and the slider 1.

[0027] The periphery of the fixed plate 4 is provided with a plurality of air intake holes 5, which are connected to the air intake end of the turbine fan 7. The bottom of the gas monitoring seat 3 is provided with an exhaust hole 8 for connecting to the air outlet end of the turbine fan 7.

[0028] The gas monitoring seat 3 is equipped with a horizontally arranged straight suction pipe 10 on the side away from the slider 1. The straight suction pipe 10 is fixedly connected to the gas monitoring seat 3 through a conical seat 9, and the center line of the straight suction pipe 10 is set directly opposite the PID sensor 6.

[0029] A swing base 11 is hinged to the end of the straight intake pipe 10 away from the gas monitoring seat 3. A gas collection hood 12 is provided at the bottom of the swing base 11. A flexible tube 13 for connecting the straight intake pipe 10 and the gas collection hood 12 is provided inside the swing base 11.

[0030] The turbine fan 7 provides power for the airflow, causing the air to pass sequentially through the air collection shroud 12, the flexible tube 13, and the intake straight tube 10 before being blown to the PID sensor 6.

[0031] The PID sensor 6 is a high-sensitivity sensor for detecting volatile organic compounds (VOCs) and other toxic gases, and its specific structure belongs to the prior art.

[0032] The top of the swing base 11 is hinged to one end of the electric telescopic rod 14, and the other end of the electric telescopic rod 14 is hinged to the support 15, which is fixed to the gas monitoring base 3. The electric telescopic rod 14 can drive the swing base 11 and the gas collecting hood 12 to rotate at a certain angle along the hinge, thereby adjusting the gas collecting hood 12's suction angle.

[0033] An alarm 16 is fixedly installed on the gas monitoring base 3. Both the PID sensor 6 and the alarm 16 are connected to the control unit. The alarm 16 will be triggered when the PID sensor 6 detects that the gas exceeds the standard.

[0034] The specific working principle of this utility model is as follows: According to the monitoring requirements, the operator adjusts the height of the equipment by using slider 1 and adjusts the angle of the gas collection hood 12 by using electric telescopic rod 14 to align it with the area to be monitored; the turbine fan 7 is started, and external air is actively drawn in from the gas collection hood 12, forming a concentrated airflow through flexible tube 13 and intake straight pipe 10. The airflow is precisely blown to the detection unit of PID sensor 6. PID sensor 6 analyzes the gas composition and concentration in real time, and the detected gas is discharged from the exhaust port at the bottom of gas monitoring base 3; the control unit continuously reads the data from PID sensor 6, and once the concentration exceeds the standard, the alarm 16 is immediately activated to issue an audible and visual alarm.
