Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment, and particularly relates to a detection equipment for a gas leakage monitoring probe. Background Technique

[0002] A gas leakage monitoring probe is a device specifically used to detect gas leakage. It can detect gas leakage and send out an alarm in time to avoid potential dangers. Such a probe usually consists of a sensitive element, a signal processing module, and an alarm system. The sensitive element is the core part for detecting gas leakage, and common types include semiconductors, electrochemistry, and infrared rays, etc. When gas leaks, the sensitive element can sense the change in gas concentration and send a signal to the signal processing module. The signal processing module receives the signal from the sensitive element and processes and analyzes it. The alarm system can use an audible and visual alarm, mobile phone text message notification, etc. to timely remind users of the gas leakage situation.

[0003] In the prior art, a test device for a gas leakage monitoring probe (publication number: CN215678371U) is provided. The device includes a detection rod, a connecting pipe, a gas storage mechanism, and a closing mechanism; one end of the connecting pipe is fixedly connected to one end of the detection rod, and the other end of the connecting pipe communicates with the gas storage mechanism; the closing mechanism can be closed between the connecting pipe and the gas storage mechanism. The advantages of the utility model are as follows: This test device for the gas leakage monitoring probe avoids high-altitude operations, saves manpower and material resources, and improves the safety of operation.

[0004] However, this device still has the following defects:

[0005] When this device is in use, the gas directly discharges to the lower end of the detection probe through the connecting pipe. When the gas discharges from the connecting pipe, it will diffuse around, affecting the detection accuracy. At the same time, external interfering substances will also interfere with gas detection. Therefore, we need to propose a detection equipment for a gas leakage monitoring probe. Content of the Utility Model

Both rotating shafts 53 are rotatably connected to the U-shaped frame 51. A plurality of annularly distributed limiting holes 54 are opened inside the rotating block 52. A limiting frame 55 is slidably connected inside the limiting holes 54. The limiting frame 55 is slidably connected to the U-shaped frame 51. A spring 56 is sleeved outside the limiting frame 55. An installation shell 57 is slidably connected to the outside of the limiting frame 55. The installation shell 57 is fixedly connected to the U-shaped frame 51.

[0025] The upper end of the rotating block 52 is fixedly connected to a connecting rod 6, and the upper end of the connecting rod 6 is fixedly connected to an air hood 7.

[0026] A spherical bladder 2 is arranged outside the telescopic rod 1. A connecting pipe 3 is fixedly connected to the outside of the spherical bladder 2. The connecting pipe 3 is fixedly connected to the air hood 7.

[0027] Exemplarily, gas is stored inside the spherical bladder 2, which is convenient for discharging the gas to the position of the detection probe during detection.

[0033] Exemplarily, the sealing shell 91 and the sealing cover 92 cooperate to seal the outer side of the photographic probe 8, avoiding the problem that when gas enters the inside of the air hood 7, the photographic probe 8 is an electrical appliance and has a certain danger during use.

The sealing shell 91 and the sealing cover 92 cooperate to seal the outside of the photographic probe 8, avoiding the problem that when gas enters the inside of the gas hood 7, the photographic probe 8 is an electrical appliance and has certain dangers during use.
