Description

Technical Field

[0001] The utility model relates to the technical field of detectors, in particular to a gas leakage detector. Background Technique

[0002] The gas leakage alarm is a very important gas safety device. In industrial production, the gas pipelines in industrial plants need to be repaired and inspected every year, mainly to detect whether there is a leakage phenomenon. When encountering a gas leakage situation, gas maintenance personnel need to rush to the scene immediately to find the leakage point and then carry out emergency repairs. The Chinese authorized utility model patent (publication number: CN221004754U) discloses a gas leakage detector. When in use, the catheter can be limited and stored according to needs, and the catheter and the probe are limited and stored on one side of the detector, avoiding the problem that during the detection process, due to the catheter driving the connecting hoses and the probe at both ends to swing randomly, it is easy to cause damage to the instrument and reduce the service life of the instrument.

[0003] However, the above device still has some deficiencies when in use. Specifically, since the probe is installed on the detector through a hose, its detection range mainly depends on the distance and direction of the operator holding the detector and moving. However, in some areas with narrow space and complex structure, it is difficult for the operator to insert the detector and the probe deep into the target position, resulting in certain errors in the gas leakage detection in these areas and increasing potential safety hazards. Therefore, a gas leakage detector is proposed for the above situation. Content of the Utility Model

One end of the catheter away from the detector housing is provided with a probe. A rotating shaft is provided on one side of the outer wall of the detector housing.

[0007] An assembly hole is penetrated through the base. The assembly hole cooperates with the rotating shaft. A telescopic member is provided on the top of the base. The end of the telescopic member away from the base is provided with a mounting seat.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0024] Refer to Figures 1-4 , a gas leakage detector, including a detector housing 1 and a base 3. The cross-sectional projection of the base 3 is in a "T" shape. A duct 101 is provided on the detector housing 1. The duct 101 is a rubber hose. A probe 102 is provided at one end of the duct 101 away from the detector housing 1. A rotating shaft 2 is provided on one side of the outer wall of the detector housing 1.

[0025] An assembly hole 301 is penetrated through the base 3. The assembly hole 301 cooperates with the rotating shaft 2. A telescopic member 4 is provided on the top of the base 3. An end of the telescopic member 4 away from the base 3 is provided with a mounting seat 5.

[0026] The mounting seat 5 includes a cylinder 501. An arc-shaped block 502 is provided on the cylinder 501. The number of the arc-shaped blocks 502 is two. Arc-shaped grooves are provided on both of the two arc-shaped blocks 502. Three springs 503 are fixedly connected to the surfaces of the two arc-shaped grooves. One end of the three springs 503 away from the arc-shaped block 502 is fixedly connected to an arc-shaped clamping plate 504. The probe 102 is clamped by the two arc-shaped clamping plates 504. A groove 505 is opened at the top of the cylinder 501.

[0027] In this implementation mode, during use, the telescopic member 4 is rotated to the position as shown in Figure 1 . Then, hold the probe 102 and clamp the probe 102 between the two arc-shaped clamping plates 504. Under the self-adaptation of the spring 503, the two arc-shaped clamping plates 504 clamp the probe 102. Then, adjust the elongation length of the probe 102 through the telescopic member 4, so that the probe 102 can flexibly extend to a space-limited position that was originally difficult to reach, thereby broadening the detection range of the detector, ensuring the comprehensiveness and accuracy of gas leakage detection, enabling the detector to be flexibly adjusted according to different detection requirements, and enhancing its applicability and flexibility.

[0028] After the detection operation is completed, remove the probe 102, rotate the telescopic member 4 so that the telescopic member 4 rotates 180°, and at the same time insert the probe 102 into the groove 505, and clamp the conduit 101 through the arc-shaped clamping plate 504 to achieve the protection treatment of the groove 505 and prevent the groove 505 from being contaminated and affecting subsequent detection use.

[0029] In this embodiment, as Figure 1 shown, a detector body and a processor are provided inside the detector housing 1. A display screen and control keys are provided on the detector housing 1. The detector and the processor are electrically connected to the display screen and the control keys.

[0030] In this embodiment, when the device performs detection work, the control keys and the probe 102 can be used to detect the air. The detector and the processor process the data and display it through the display screen.

[0031] In this embodiment, as Figure 1 shown, an alarm flashing light and a voice prompt are respectively provided on the top of the detector housing 1. The alarm flashing light and the voice prompt are both electrically connected to the processor inside the detector housing 1.

[0032] In this embodiment, when the gas detection is abnormal, the processor gives signals corresponding to the alarm flashing light and the voice prompt, so that the alarm flashing light and the voice prompt generate light flashing and voice alarms.

[0033] In this embodiment, as Figure 1 shown, a handle is fixedly connected to one side of the detector housing 1 away from the base 3.

[0034] In this embodiment, the staff can hold the detector housing 1 by using the handle, and the user's palm can pass through the handle for use, which increases the stability of holding.

[0035] In this embodiment, as Figure 3 shown, a rubber pad is provided on the surface of the arc-shaped clamping plate 504 away from the spring 503, and the rubber pad has anti-slip lines.

[0036] In this embodiment, the use of the rubber pad and the anti-slip lines increases the friction with the surface of the probe 102 and also avoids abrasion of the surface of the probe 102.

[0037] In this embodiment, as Figure 1 and Figure 2 shown, the telescopic member 4 is a telescopic rod. The telescopic rod includes a first rod body. An activity cavity is provided at the top of the first rod body. A second rod body is fitted in the activity cavity with a clearance. A friction surface is provided on the surface of the second rod body. The top of the second rod body is fixedly connected to the mounting seat 5.

[0038] In this embodiment, the provision of the friction surface increases the frictional force between the second rod body and the movable cavity, such that the second rod body will not easily slide within the movable cavity, ensuring stability after elongation. The friction surface may be in the form of anti-slip patterns provided.

[0039] In this embodiment, as Figure 1 and Figure 2 shown, the telescopic member 4 is an electric push rod, and the movable end of the electric push rod is fixedly connected to the mounting seat 5.

[0040] In this embodiment, a small electric push rod is adopted for the electric push rod, and the electric push rod is externally connected to a power source.

[0041] As described above, the above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
