Description

Technical Field

[0001] The utility model relates to the technical field of boiler detection, in particular to a boiler pressure vessel leakage detection device. Background Art

[0002] Boiler pressure vessels are important equipment in industrial production, and their safety has a significant impact on the production process and personnel safety. Existing boiler pressure vessels often have poor sealing performance that affects their quality. Leakage detection is an important means to ensure the safe operation of boiler pressure vessels. Among them, the "A boiler pressure vessel leakage detection device" disclosed by the authorization announcement number "CN207662576U" has solved the problem that the helium leak detector and the helium cylinder are both heavy. At the same time, the helium leak detector has a rectangular shape, while the helium cylinder has a cylindrical shape. The different shapes of the two bring inconvenience to their joint transportation. In addition, the vibration generated during transportation and movement often has a certain impact on the internal components of the helium leak detector. Moreover, the helium cylinder lacks a shock absorbing device. Once a violent collision occurs during transportation, it is easy to explode, threatening the personal safety of the staff. After further searching, it was found that the "A boiler pressure vessel leakage detection device" disclosed by the authorization announcement number "CN213779429U" has a variety of disadvantages. Through the specific technical structure setting, the problem that traditional pressure detection methods are all interventional is effectively solved, that is, it is necessary to open a hole in the pressure vessel to draw pressure so as to guide the pressure to the pressure sensor. At the same time, the temperature of a general boiler is relatively high, and a general sensor is easily damaged. However, in actual use, boiler pressure vessel leakage detection devices with similar structures still have many defects, such as: the commonly used boiler leakage detection device is not convenient to adjust itself according to the size of the boiler, which makes it inconvenient for personnel to operate and use, and may cause missed detection. The boiler leakage detection device generally needs to contact with the boiler, and the detection accuracy is not high. It is impossible to accurately locate the leakage position, which is not convenient for subsequent maintenance work. Therefore, it is necessary to design a boiler pressure vessel leakage detection device. Utility Model Content

[0003] The purpose of the utility model is to provide a boiler pressure vessel leakage detection device to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a boiler pressure vessel leakage detection device, comprising a base plate, a guide rail is fixedly installed on the top of the base plate, a servo motor is fixedly connected to one end of the guide rail, a lead screw is fixedly installed on the output end of the servo motor, a slide plate is movably installed on the periphery of the lead screw, an electric push rod is fixedly connected to the top of the slide plate, a support plate is bolted to the top of the electric push rod, a detection device is fixedly connected to the top of the support plate, a laser emitter is fixedly installed inside the detection device, an interferometer is fixedly connected inside the detection device at the bottom of the laser emitter, and a probe is fixedly installed on the other end of the detection device.

[0005] When in use, the mobile device is moved to the side of the boiler, and the servo motor drives the lead screw to rotate, so that the slide plate moves horizontally to adjust the horizontal position of the detection equipment. The electric push rod drives the support plate to move upward to adjust the height of the detection equipment, thereby enabling the user to adjust the position of the detection equipment according to the size of the boiler, avoiding the phenomenon of missed detection during the detection of the detection equipment, which may cause errors in the boiler detection results. The detection equipment is powered on and the laser transmitter emits laser through the probe to illuminate the boiler surface, which is then reflected to the probe and enters the interferometer. The interferometer analyzes and processes the received laser and generates an interference pattern, thereby meeting the needs of boiler surface leakage detection and being able to accurately locate the leakage position, which is convenient for subsequent maintenance personnel to maintain the boiler, improves the accuracy of boiler leakage detection, and avoids the harm that may be caused by boiler leakage.

[0006] Preferably, an operation panel is fixedly mounted on one end of the detection device, and a display screen is fixedly connected to one end of the detection device on the top of the operation panel. The user can output command information to the control module through the operation panel, thereby meeting the user's needs for device adjustment.

[0009] Preferably, filter windows are fixedly installed inside the two sides of the detection device, and a fan is fixedly installed inside the detection device on the laser transmitter side. The filter windows can filter the air entering the detection device, reduce the accumulation of dust inside the detection device, and avoid excessive dust accumulation causing damage to the inside of the detection device.

[0010] Preferably, support feet are fixedly installed at the bottom of the base plate, and rollers are fixedly connected to the bottom of the base plate between the support feet. The support feet increase the contact area between the base plate and the ground, enhance the stability of the device, and avoid shaking during the operation of the device to affect the detection of the boiler. The rollers facilitate the user to move the device, save the working time of the device movement, and improve the working efficiency of the device movement.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. Through the combination of servo motor, slide plate and electric push rod, the servo motor can move the slide plate horizontally to adjust the horizontal position of the detection equipment, and the electric push rod can adjust the height of the detection equipment, thereby enabling the user to adjust the position of the detection equipment according to the size of the boiler, avoiding the phenomenon of missed detection during the detection process of the detection equipment, which may lead to errors in the boiler detection results.

Through the combination of laser transmitter, probe and interferometer, the laser transmitter emits laser through the probe to illuminate the boiler surface, and then reflects to the probe and enters the interferometer. The interferometer will analyze and process the received laser and generate an interference pattern, thereby meeting the needs of boiler surface leakage detection and being able to accurately locate the leakage position, which is convenient for subsequent maintenance personnel to maintain the boiler, improves the accuracy of boiler leakage detection, and avoids the harm that may be caused by boiler leakage.
