[0002] Petrochemical refers to the processing industry that uses petroleum and natural gas as raw materials to produce petroleum products and petrochemical products. The transportation of raw materials in the petrochemical processing and production process is mainly carried out through complex pipelines, and the sealing performance of the pipeline joints or valve joints is crucial and directly related to safe production. Therefore, the inspection and maintenance of pipeline joints or valves cannot be missed. In the prior art, the inspection and maintenance of sealing parts is mainly carried out by manually holding oil and gas detectors to detect suspected leaks. For points where there is an obvious leak, the staff can find it through observation. If it is rainy or the pipeline is in a wet and humid environment, it is impossible to make a direct judgment manually. When using the detector for detection, it is necessary to ensure that no detection points are missed. However, in actual operation, on the one hand, the operator will ignore some detection points, and for the pipeline connection flange, omissions will occur during the bypass detection. In addition, due to the limitations of the layout position of the pipeline, the manual detection operation space is small, which is inconvenient to complete the detection. Utility Model Content

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0021] Please refer to Figure 1-5 , the present utility model provides a technical solution for a portable electrical alarm device for inspection and maintenance:

[0022] A portable electrical alarm device for inspection and maintenance includes an arc-shaped frame 3, the arc-shaped frame 3 is erected on the periphery of the pipeline 1, the arc-shaped frame 3 can rotate along the periphery of the pipeline 1, the arc-shaped frame 3 is made of stainless steel square pipe, the cross-section of the arc-shaped frame 3 is in a "U" shape, in order to reduce the storage space and facilitate carrying, the arc-shaped frame 3 is composed of at least two arc-shaped rods 6, as Figure 1 , Figure 2 shown, in this embodiment, two arc-shaped rods 6 are provided, and the two arc-shaped rods 6 are rotatably connected. When in the storage state, the two arc-shaped rods 6 are folded and arranged side by side to save storage space.

[0023] In order to adapt to pipelines 1 with different diameters, telescopic positioning rods 11 are arranged on the inner side of the arc-shaped frame 3. In this embodiment, four positioning rods are provided, and the four positioning rods are distributed at intervals along the arc-shaped frame 3. The telescopic positioning rod 11 includes a rotating rod 12, a telescopic rod 13, and a wheel frame 14. The rotating rod 12 is rotatably arranged on the arc-shaped frame 3, the telescopic rod 13 is slidably arranged along the rotating rod 12, a spring is arranged in the rotating rod 12, the wheel frame 14 is fixed at one end of the telescopic rod 13 away from the rotating rod 12, and the roller 15 is rotatably arranged on the wheel frame 14. When the two arc-shaped rods 6 are in the folded state, the telescopic positioning rod 11 is in the storage state, and the rotating rod 12 rotates along the arc-shaped frame 3 to as Figure 1When the arc frame 3 is positioned and arranged on the side of the pipeline 1 by the telescopic positioning rod 11, the telescopic positioning rod 11 rotates along the arc frame 3 to the position as shown in FIG. Figure 3 The arc frame 3 is shown in a radial state and fixed.

[0024] A fixed seat 7 is also provided on the arc frame 3. The fixed seat 7 is slidably arranged along the arc frame 3. The fixed seat 7 is used to fix the oil and gas detector 2. Two clamps 10 are symmetrically arranged on the fixed seat 7. The clamps 10 are rotatably arranged on the fixed seat 7. A torsion spring is arranged at the rotation axis of the clamp 10. A rubber layer is arranged on the surface of the clamp 10. The two clamps 10 clamp the oil and gas detector 2 and fix it on the fixed seat 7.

[0025] The specific sliding mode of the fixed seat 7 along the arc seat is that the outer periphery of the arc frame 3 is embedded with an arc friction plate 4, the front and rear sides of the arc frame 3 are provided with a limited guide groove 5, the fixed seat 7 is adapted and clamped on the arc frame 3, and a positioning guide bolt 9 is provided on the fixed seat 7, and the positioning guide bolt 9 is adapted to the limited guide groove 5, and friction wheels are rotatably provided at both ends of the fixed seat 7, and a coil spring is provided at the rotating shaft of the friction wheel, and the friction wheel contacts the arc friction plate 4. In the process of the fixed seat 7 moving from one end to the other end, under the contact between the friction plate and the friction wheel, the friction wheel rotates and causes the coil spring to store force, so after the coil spring on the fixed seat 7 stores force, after the constraint on the fixed seat 7 is released, the fixed seat 7 will drive the oil and gas detector 2 to slide along the arc frame 3. Therefore, in order to have a constraint between the arc frame 3 and the fixed seat 7, a limit buckle 8 is provided at the end of the fixed seat 7, and the limit buckle 8 is rotatably provided on the fixed seat 7. A torsion spring is provided at the rotation axis of the limit buckle 8. When the fixed seat 7 slides to one end of the arc frame 3, the limit buckle 8 contacts the end of the arc frame 3, and the fixed seat 7 cannot slide along the arc frame 3. After pressing the limit buckle 8 to make the limit buckle 8 break away from the contact with the end of the arc frame 3, the fixed seat 7 slides along the arc frame 3 under the action of the coil spring.

[0026] Working principle: The portable inspection and maintenance electrical alarm device of the present application is mainly based on the alarm detection function of the oil and gas detector 2, and the auxiliary oil and gas detector 2 can accurately and without omission detect the flange connection seal of the pipeline 1.

[0027] When performing a seal inspection on the connection of the oil and gas transport pipeline 1, especially in rainy weather when the surface of the pipeline 1 is wet, in order not to miss the inspection, the arc frame 3 is first unfolded as a whole, and the telescopic positioning rod 11 is rotated to a radial state along the arc frame 3 and fixed. The arc frame 3 is sleeved on the pipeline 1 as a whole through the opening of the arc frame 3, and the arc frame 3 is sleeved on the side of the pipeline 1 under the action of multiple telescopic positioning rods 11. Then, the fixed seat 7 is moved from one end of the arc frame 3 to the other end by sliding the fixed seat 7, and in this process, the friction wheel on the fixed seat 7 rotates and drives the coil spring to store force, and at the same time, the limit buckle 8 is clamped with the end of the arc frame 3. Finally, the oil and gas detector 2 is installed between the two clamps 10 and fixed by the clamps 10, and then the position of the oil and gas detector 2 is adjusted so that the probe position of the oil and gas detector 2 corresponds to the position to be detected. Finally, by releasing the limit of the fixed seat 7 by the limit buckle 8, under the action of the coil spring, the fixed seat 7 drives the oil and gas detector 2 to detect the connection ring seam to be detected. Since it is impossible to complete the one-week annular detection of the pipeline 1 through one detection, it can generally be completed through two operations. If a leak point occurs during the detection process, the corresponding oil and gas detector 2 will generate an alarm.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
