Description

Technical Field

[0001] The utility model relates to the field of instrument detection devices, in particular to an instrument detection alarm device. Background Art

[0002] When conducting pipeline gas detection, instrument detection devices are required. These devices can accurately determine whether there is a gas leak in the pipeline through the information displayed on the instrument. Once a gas leak is detected, the detection device will immediately send a clear alarm to the inspectors, informing them that there is a gas leak and that immediate maintenance is required.

[0003] Currently, in the process of pipeline gas leak detection, a common method is to use a handheld gas sensor probe to directly approach the pipeline for detailed inspection. However, this method is limited by the small detection range of a single probe, resulting in low efficiency in leak detection and difficulty in quickly and accurately locating the leak point.

[0004] Therefore, in view of the situation that a single probe is used for detection during the above-mentioned pipeline gas leakage detection process, resulting in low detection efficiency, an instrument detection alarm device can be designed. Through the gear set transmission structure and the threaded transmission structure, the device can be automatically moved to conduct a comprehensive detection of the pipeline. Utility Model Content

[0005] In order to overcome the problem of low detection efficiency caused by using a single probe for detection during pipeline gas leakage detection.

[0006] The technical solution of the utility model is: an instrument detection alarm device, including a base plate, an axle, a wheel, an electric lifting rod, a power component, an adjustment component, and a detection alarm component; two sets of axles are installed at the lower end of the base plate, wheels are installed at the left and right ends of the axles, a box warehouse for protecting the electric lifting rod is provided at the upper end of the base plate, an electric lifting rod for adjusting the height is installed in the box warehouse, a power component that is rotated by a motor-driven gear set is installed at the upper end of the axle and is located at the lower end of the base plate, an adjustment component that is driven by a thread is installed at the left end of the electric lifting rod, a detection structure in the detection alarm component is installed at the lower end of the adjustment component, and an alarm structure in the detection alarm component is installed at the right end of the box warehouse on the base plate.

[0007] Preferably, the box bin on the upper end of the bottom plate is used to protect the electric lifting rod to prevent interference and damage from the external environment.

The electric lifting rod is driven by a motor to achieve the function of up and down lifting to meet the detection needs of pipelines of different heights. The power component drives the gear set to rotate through the motor, which provides power support for the entire device so that the device can move. The adjustment component achieves fine-tuning of the detection structure through threaded transmission to meet the detection needs of pipelines of different sizes. The detection alarm component includes a detection structure and an alarm structure. The detection structure is installed at the lower end of the adjustment component to detect whether there is a gas leak in the pipeline.

When the rotating shaft rotates, gear No. 1 will also rotate accordingly, and it meshes with gear No. 2 to transmit the rotational motion of the rotating shaft to the axle through gear transmission. The tooth ratio of gear No. 1 and gear No. 2 determines the relationship between the rotational speed of the axle and the rotational speed of the rotating shaft. By adjusting the gear ratio, the rotational speed of the axle can be changed, thereby adjusting the moving speed of the device.

When the bidirectional threaded rod rotates, the movable seat threadedly connected to it will move in opposite directions respectively to realize the adjustment function, thereby meeting the detection requirements of pipes of different sizes.

[0012] Preferably, the detection alarm component includes a No. 1 semicircular rod and a No. 2 semicircular rod; the lower end of the movable seat is respectively equipped with a No. 1 semicircular rod and a No. 2 semicircular rod for detecting gas. The No. 1 semicircular rod and the No. 2 semicircular rod are the main structures of the detection alarm component, and gas detection can be performed along the outer wall of the pipeline. The semicircular rods can be made of corrosion-resistant and aging-resistant materials to meet long-term usage requirements.

[0013] Preferably, the detection alarm component also includes a gas sensing probe and a gas detector; the gas sensing probe for absorbing gas is installed on the inner wall of the No. 1 semicircular rod and the No. 2 semicircular rod, and a warning light for alarm is provided on the upper end of the gas detector.

[0028] See also Figure 6 In this embodiment, the detection alarm component includes a semicircular rod 701 No. 1 and a semicircular rod 702 No. 2; the lower end of the movable seat 604 is respectively installed with a semicircular rod 701 No. 1 and a semicircular rod 702 for detecting gas, and the detection alarm component also includes a gas sensing probe 703 and a gas detector 704; the gas sensing probe 703 for absorbing gas is installed on the inner wall of the semicircular rod 701 No. 1 and the semicircular rod 702 No. 2, and a warning light for alarm is arranged on the upper end of the gas detector 704, and the gas detector 704 is installed at the front end of the bin on the bottom plate 1, and the semicircular rod 701 No. 1 and the semicircular rod 702 No. 2 are the main structures of the detection alarm component, and gas detection can be performed along the outer wall of the pipeline, and the semicircular rods can be made of corrosion-resistant and anti-aging materials. The gas sensing probe 703 is a component used to absorb and detect gas.

When an abnormal gas concentration is detected, the warning light will light up to alert the detection personnel.

[0029] During the operation, the inspector first starts the electric lifting rod 4 to smoothly lift the adjustment assembly above the pipe, and then starts the second rotating motor 602, which drives the bidirectional threaded rod 603 to rotate. When the bidirectional threaded rod 603 rotates, the moving seat 604 tightly connected to its thread will move in opposite directions respectively.

[0030] Next, start the No. 1 rotating motor 501, which will drive the rotating shaft 502 to start rotating, and the No. 1 gear 504 connected to the rotating shaft 502 will also rotate accordingly. Since the No. 1 gear 504 and the No. 2 gear 505 are meshed with each other, through the principle of gear transmission, the rotational motion of the rotating shaft 502 is effectively transmitted to the axle 2, so that the whole device can move above the pipeline;

[0031] While the device is moving, the gas sensing probes 703 on the inner walls of the first semicircular rod 701 and the second semicircular rod 702 start to work to detect whether there is a gas leak on the outer wall of the pipeline. Once the gas is sensed, these probes will quickly convert this information into electrical signals and transmit these signals to the gas detector 704;

[0032] After receiving the electrical signal from the gas sensing probe 703, the gas detector 704 will immediately perform analysis and processing. Once an abnormal gas concentration is detected, such as a leak or excessive harmful gas, the warning light will immediately light up, alerting the detection personnel in a conspicuous manner and allowing them to take necessary safety measures.

[0033] Through the above steps, through the close cooperation of the power component and the adjustment component, not only can stable and continuous power output be provided to ensure that the entire device can move smoothly during the detection process, but it can also be accurately adjusted according to the actual pipeline size to meet diverse detection needs. At the same time, the detection alarm component continuously monitors the gas status. Once an abnormal situation such as a gas leak is detected, the alarm mechanism will be immediately activated to notify the detection personnel in time, prompting them to quickly take corresponding safety measures, thereby solving the problem of low detection efficiency caused by using a single probe for detection during pipeline gas leakage detection.
