[0001] This utility model belongs to the field of pressure gauge monitoring technology, and specifically relates to a pressure gauge monitoring device. Background Technology
[0002] Pressure gauges are widely used in pressure-bearing special equipment such as pressure pipelines, pressure vessels, and boilers. Their display accuracy and reliability play a crucial role throughout the lifecycle of such equipment, especially in pressure tests during the manufacturing, installation, modification, and repair of this equipment. These tests directly impact the success of the pressure tests and the safety of personnel involved. Pressure tests on pressure-bearing special equipment are vital for verifying design specifications and ensuring product quality, and they also serve as a point of contention in the inspection process.
[0003] According to the requirements of construction acceptance standards and supervision rules, personnel involved in pressure testing and inspection need to regularly observe and record the pressure gauges during the testing process. During pressure testing, the testing equipment often has to withstand 1.0 to 2.0 times the design pressure, and the test pressure ranges from 0.1 MPa to 501 MPa. Frequent personnel approaching the testing equipment poses a significant safety risk, especially in the manufacture, installation, modification, and repair of pressure-bearing special equipment, where accidents such as weld cracking, nozzle or end cap ejection may occur during pressure testing. Therefore, a pressure gauge monitoring device is needed to address this issue. Utility Model Content

[0008] Furthermore, the clamping block includes an L-shaped first clamping block and an I-shaped second clamping block;
[0009] The short rod portion of the first clamping block is located on the left side of the pressure gauge, and the connecting rod is hinged to the short rod portion.

[0012] The advantages of this utility model are: This utility model provides a pressure gauge monitoring device, which enables accurate, safe and real-time monitoring and recording of pressure gauges through a remote pressure gauge monitoring device. It not only meets the requirements of construction acceptance standards and inspection rules for pressure gauge accuracy and timed recording, but also avoids the problem of safety hazards caused by frequent close-range observation and recording of instruments by personnel.

[0024] Example 1
[0025] This embodiment provides, for example Figures 1-3The pressure gauge monitoring device shown includes a pressure gauge 1 with its scale facing left. A monitoring device 2 is located on the left side of the pressure gauge 1. The monitoring device 2 includes a waterproof and dustproof housing 21, with a camera 22 located in the center of the housing 21. The camera 22 is a standard camera, employing a high-definition standard camera 22 with night vision and autofocus functions. The standard lens provides an image closer to human vision, ensuring the accuracy of the detected pointer readings. Because the pressure test environment is complex and diverse, the pressurization and holding processes are conducted continuously at night, making it impossible to guarantee sufficient lighting during these processes. Therefore, a certain level of night vision capability is required. The lens image is clear enough, and the lens used should have a certain autofocus function. The camera 22 is facing the scale of the pressure gauge 1. In addition to the standard camera 22 and waterproof and dustproof housing 21, the monitoring also includes a temperature sensor. The temperature sensor is a thermistor type temperature sensor, which has high sensitivity and low cost. The temperature range is generally -50℃ to 150℃, which meets the requirements for detecting the ambient temperature during the pressure test. The housing 21 is made of plastic. The hinge interface between the back of the housing 21 and the connecting rod 32 is arranged in an equilateral triangle. The waterproof and dustproof housing 21 has the camera 22 and temperature sensor data interface on the side. The data interface has a waterproof and dustproof protective cover.
[0026] A fixing component 3 for securing the monitoring device 2 is provided between the pressure gauge 1 and the monitoring device 2. The fixing component 3 includes several U-shaped clamps 31, which are fixed to the pressure gauge 1 and arranged circumferentially around the pressure gauge 1. Since the surface of the scale of the pressure gauge 1 is mostly made of glass, while the opposite side of the scale (i.e., the back side of the pressure gauge 1) is a metal shell, a padding layer is laid on the inner wall of the clamps 31 that are fixed to the pressure gauge 1 to prevent damage to the scale of the pressure gauge 1 during clamping. A connecting rod 32 is provided between the clamps 31 and the outer shell 21. The connecting rod 32 is made of hollow, lightweight metal rod. One end of the connecting rod 32 is hinged to the right side of the outer shell 21, and the other end of the connecting rod 32 is hinged to the clamps 31. Considering the change in the diameter of the pressure gauge 1 dial, the camera lens angle, and the clarity of the image, the connecting rod 32 is equipped with 15mm diameter... One set each of the 0mm and 250mm specifications is provided. The clamping block 31 includes an L-shaped first clamping block 311 and an I-shaped second clamping block 312. The short rod of the first clamping block 311 is located on the left side of the pressure gauge 1, and the connecting rod 32 is hinged to the short rod. The long rod of the first clamping block 311 is vertically fixed with a screw 33 on the end face away from the connecting rod 32. The second clamping block 312 is slidably sleeved on the screw 33. A nut 34 is provided on the side of the second clamping block 312 away from the first clamping block 311. The nut 34 is threaded onto the screw 33. By setting the camera 22 directly in front of the pressure gauge 1, it is ensured that the image of the pressure gauge 1 captured by the camera 22 does not show pointer deviation and the accuracy of the data analysis module identification. The nut 34 is a wing nut, so that the staff can manually tighten it without the need for wrenches or other tools during on-site use.
[0027] The pressure gauge 1 has a vertically installed pressure tap 4 at its bottom, with a valve 8 on the pressure tap 4. The lower end of the pressure tap 4 is fixedly connected to a pressure-bearing device 5, which is a pressure pipeline, pressure vessel, boiler, or other pressurized equipment that needs to be pressure tested. It also includes an integrated module 6, which is an integrated unit of a data analysis and processing module, a data storage module, a remote data transmission module, an abnormal alarm module, and a power supply module. It is equipped with a protective housing, and the side of the protective housing has a camera 22 data interface, a data storage module data export interface, a power supply module switch, a power supply module power display, a power supply module charging interface, an external power interface, and a heat dissipation window (the protective housing is a split type that can be inspected and repaired, and has waterproof, dustproof, and certain resistance to external impact). The integrated module 6 is connected to the monitoring device 2 through a wiring harness 7, which is a data transmission cable between the camera 22, the temperature sensor, and other integrated modules 6.
[0028] In summary, this utility model provides a pressure gauge monitoring device that enables accurate, safe, and real-time monitoring and recording of pressure gauge 1 through a remote pressure gauge 1 monitoring device. This not only meets the requirements of construction acceptance standards and inspection rules for the accuracy and timed recording of pressure gauge 1, but also avoids the problem of safety hazards caused by frequent close-range observation and recording of instruments by personnel.
[0029] Furthermore, if the inspection rules allow in the future, inspectors can witness the inspection process through remote on-site instrument monitoring terminals, which reduces the time and economic costs for inspectors to travel to and from the inspection site, reduces the manual cost of pressure test recording and the waiting time cost for inspection by the inspected unit, improves the production efficiency of the inspected unit, and also realizes the digitalization, visualization, traceability and standardized recording of pressure tests.
[0030] Meanwhile, through wireless network technology, real-time video recording module, real-time data recognition module, data analysis module, and abnormal data alarm module, test personnel and inspection personnel can monitor the status of local instruments and receive alarm information in real time at the receiving terminal, and respond to sudden abnormal situations that occur on site immediately.
[0031] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
